The Civil War Of African Americans - 1010 Words

One can only begin to imagine the life for a slave during the mid-late nineteenth century. For an African American, the word â€Å"life† evolved from a word that meant absolutely nothing, to a word that stood for an individual’s highest commodity. After the civil war, emancipation for slaves transformed from a dream to a reality. Although the civil war finally ended in 1865 after four years of fighting, certain citizens and groups across the nation still remained in a state if disagreement with the freedom granted to African Americans. The years after the civil war revolutionized many principles that are the basis of regulations constituted in today’s society. The lives of African Americans began to change forever throughout the years after the civil war, a period otherwise known as the Reconstruction era that stretched from 1865 to 1877. Life for newly emancipated slaves during the Reconstruction era consisted of living with the fear of confrontation with hate -groups, as well as opposing unconstitutional laws, and challenging equality in the United States. If you were to take a walk down a random road in the south in the early 1860’s, you might see plantations with fields of cotton or some other agricultural commodity being grown there. Furthermore, in those fields you would more than likely see African American slaves tending to the crops and performing assigned tasks. Before the civil war, the life of an American slave consisted of living day to day under theseShow MoreRelatedAfrican Americans And The Civil War1076 Words   |  5 Pages Throughout history African Americans have had is bad in the United States.

Nigeria Is A Country In The Western Part Of Africa. It

Nigeria is a country in the Western part of Africa. It is one of the earliest countries to be exposed to European influence. There are three major tribes, Igbos, Yorubas and Hausas. Social status in the world in very important, It is portrayed in different forms. However, it is crucially used in Africa, the Igbos exhibit their social status with titles. In Chinua Achebe’s novel â€Å"Things fall apart†, he beautifully describes the tragic fall of the Umuofia people of the Igbo tribe in the southern part of Nigeria along the Niger. He talks about his protagonist Okonkwo, a man of strength and weakness, of caliber and pain and of perseverance and shame as he sees his world crumble before his eyes.

He even had to fend for himself, his mother, sister and father. He was given the opportunity to name a name for himself when he realized he could be hardworking by farming. It was how he got and used the opportunity that mattered to him. Okonkwo understanding the pattern of success, and trying to emulate it went to Nwakibie. Nwakibie is a man described of enormous wealth, Achebe states, â€Å"There was a wealthy man in Okonkwo’s village who had three huge barns, nine wives and thirty children. His name was Nwakibie and he had taken the highest but one title which a man could take in the clan.† (pg. 18 – 19) Okonkwo had a model to emulate that was different from his father.

During the recent old ages the application of MP3 sound codec has exploded. Typically MP3 files are played back utilizing package ( CPU or DSP ) , but recent tendencies have since informant the outgrowth of portable device, such as nomadic phones and MP3 participants. While DSP architecture is the most efficient for running MP3 participant, the challenges of FPGA execution of MP3 decrypting are less understood. Field Programmable Gate Array, merely known as FPGA, is one type of incorporate circuit that is consumer-programmable, therefore it is called â€Å"field programmable† . This incorporate circuit uses hardware descriptive linguistic communication ( HDL ) to configure. Nowadays, FPGA has since advanced into a high degree of efficiency during the past decennary. It has since become the major HP in different types of application, since it can be employed as standalone System on Chip ( SoC ) or powerful gas pedals in multi-chip system. The mark of the undertaking is to implement the MP3 decrypting nucleus by using the FPGA belongingss. While utilizing the bing package codification to run the decipherer in package, efforts has been done to run the decipherer in hardware, which will go the chief way in this undertaking. Then, comparing the public presentation of these two methods will besides be the focal point of the undertaking. Aim The aim of this undertakings are: To plan the MP3 decipherer hardware based and can be implemented in portable based design To measure the efficiency of the hardware based decipherer comparison to the common package based decipherer Problem Statement Most of the MP3 decryption designs are of in package. However, the hardware importance of the decryption design has since taken the popularity today. Therefore, several efforts have been taken to make the to the full hardware architecture of the decryption nucleus. This paper will measure the efficiency of the hardware decipherer as per package decipherer and to look into the advantages of both methods. Scope of the Undertaking The range of the undertaking includes combination of several elements such as hardware, package and electronic parts. Below are the Scopess for the undertaking. Uses Verilog HDL linguistic communication as its chief footing for programming Explore the application of Verilog utilizing Altera DE2 Board Include package programming such as C and C++ Implement the application ( partial ) utilizing downloaded package for package execution ( Quartus II 9.1, Nios II 9.1 ) Chapter 2 LITERATURE REVIEW In 1988, Hiroshi Yasuda ( Nippon Telegraph and Telephone ) and Leonardo Chiariglione had initiated the working group Traveling Pictures Experts Group ( MPEG ) to put the criterions for audio and video compaction and transmittal. The group, formed by International Organisation for Standardisation ( ISO ) and International Electrotechnical Commission ( IEC ) , has since developed into an organisation joined by members from assorted industries, universities and research establishments. One of the criterions that have created is the MPEG-1 Layer 3, or good known as MP3. MP3 is the standard format used for digital audio compaction, in which the design have 12:1 compaction ratio, from 1.4Mbps 128kbps bitrate for compact phonograph record ( Cadmium ) music. Related Studies and Previous Work It is known that MP3 decrypting procedure is a hard procedure, but several research workers and industrialist have attempted to plan the decipherer for this specific format. You read "RTL Implementation of MP3 Decoder IP Core" in category "Essay examples" For case, Faltmanet Al.( 2003 ) have stated that the designing of MP3 decrypting in portable and stand-alone participants have gained in popularity. In the study, Faltmanet Al.( 2003 ) besides stated the importance in the public presentation of these hardware MP3 decrypting based on the clock rhythms and power use. It besides includes an effort to to make an MP3 decipherer in hardware, by utilizing Xilinx FPGA board. Thuonget Al.( 2005 ) have proposed the architecture of the MP3 decryption nucleus, in which the subcores of the architecture can be separately designed, coded and tested easy. However, the design of the nucleus is coded utilizing VHDL, the older version of RTL linguistic communication. Ko and Nicolici ( 2007 ) have tested the execution of the nucleus utilizing Altera DE2 board and Xilinx multimedia board. It besides has consequences including the figure of logic elements, reversals, memories and multipliers involved. Bhargav and Yang ( 2008 ) have introduced the use of Linux-run interface on the decryption nucleus. Their research has besides opened the possibilities of animating the popular piece of consumer engineering utilizing bing hardware available in the lab. Still, the design utilizes both hardware and package constituent in their design architecture. It has few general lags due to system clock and debugging procedure. Singhet Al.( 2008 ) have proposed that the demand of hand-held participants and multimedia in nomadic phone have raised a demand for a dedicated hardware to decrypt the file formats with low power ingestion and faster acceleration. Papakonstantinouet Al.( 2008 ) have researched instance survey on the execution of drifting point math in decipherer execution to accomplish existent clip and faster decrypting procedure. In the instance survey, the writers introduce floating-point ( FP ) unit in their architecture to measure the operation velocity ; therefore naming it the FP execution of MP3 decryption. In the latest research by Moslehpouret Al.( 2013 ) , the undertaking uses NIOS II system, which is a portion of package device, to read files and produces end product from the decrypting procedure. By utilizing unafraid digital ( SD ) card as input devices, the system uses Altera DE2 board but synthesize different file format: moving ridge files, or.wav extension files. Even so, the exposure of the study have shown that running the decipherer is possible, peculiarly because of package characteristics use Altera SOPC builder in Altera Quartus 9.1 environment, in which the platform is largely used in third instruction degree. Some of the old work did even make the architectural design of MP3 decipherer, utilizing a VLSI cell-based attack. Tsaiet Al.( 2004 ) have proposed the specific architectural construction of MP3 decipherer in which it achieves a high throughput with a decreased memory demand and hardware complexness. Meanwhile, Kalpanaet Al.( 2012 ) have tried to implement the algorithm on the decreased direction set computer science ( RISC ) based ARM processor, which is far more advanced, proficient wised. All of the old work did hold its important characteristics in edifice MP3 decryption nucleus, either in hardware or package. However, the execution of MP3 decrypting IP nucleus, which uses Verilog HDL as its hardware linguistic communication, as implementing it to the full hardware based is non good discovered. Therefore, the focal point is the study is to undertake the design of MP3 decrypting nucleus, on the surface at least. Introduction to the MP3 Decoding Core Harmonizing to Kalpanaet Al.( 2012 ) , all MP3 files are divided into fragments called frames. Each frames shops 1152 samples, enduring for 26ms, which the frame rate is about 38 frame per second ( Federal Protective Service ) . The first measure to decrypt MP3 file format is by happening the start of the frame, which is called synchronism procedure, or else called initial reading. Synchroscope Before decryption, the start of the frame must be found. If the frame is interrupted, we can non happen the exact place of the following frame ( Thuonget Al., 2007 ) . The construction of the frame consists of 5 parts ; heading, cyclic redundancy cheque ( CRC ) , side information, chief informations and accessory informations. Heading CRC Side Information Main informations Ancillary Data img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/0958919.004.png"img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/0958919.003.png"img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/0958919.002.png"img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/0958919.001.png"/ Figure 2.1The MP3 bitstream format The inside informations about the frame heading is as follows: Frame Header It is a 32-bit long and has description of the frame, together with the synchronism word to separate the get downing portion of the bitstream CRC Use to look into if there is any transmittal mistake for the most sensitive informations. The CRC will merely exists when the protection spot in the heading is set. Side Information Includes the of import information needed to decrypt the chief information. This depends on the channel manner. For individual channel, 136 spots are allocated, while for double channel, 256 spot allocated ( this is tantamount to 17 bytes in individual channel, 32 bytes in dual-channel ) Main Data The chief informations portion consists of the frames that includes scalefactors, Huffman coded spots and accessory informations Ancillary Data This information can keep user-defined information. This frame country can keep optional informations such as vocal name or song information. Huffman Decoding This subdivision contains one of the most of import undertaking in MP3 decryption. The undertaking of Huffman decrypting is to transform and mapping the information into scalefactors and symbols stand foring the 576 original frequence lines for each granule. These frequence line is divided into three divider ;Big-values,Count1andRzero. img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/0958919.005.png" img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/0958919.006.png" Big-values Count1 Rzero img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/0958919.008.png"img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/0958919.007.png"/ img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/0958919.010.png"img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/0958919.009.png"/ Figure 2.2The three parts of frequence line Detailss on the Huffman codification divider are as follows: Big-values Represents the lowest frequence lines and are coded with the highest preciseness, scaled from values between -15 to 15. When the decipherer finds the value 15, it assumes that the higher preciseness is needed. This can be done by utilizing the value 15 as an flight codification, so reads extra spots from the imput watercourse. The figure specified in the Huffman tabular array are called linbits. Count1 Represent the higher frequence lines ; non necessitate the higher preciseness scaled value. Ranging from -1 to 1. Rzero Represent the highest frequence lines, and non portion of the bitstream. It contains the the frequence lines that are removed by the encoder. These values are filled with nothing by the decipherer. Requantiser The symbols generated from Huffman decrypting is so reconstructed into the original frequence line by utilizing the scalefactors provided in the side information of the frame. The low frequence scalefactor set contains less values than the high frequence. The descaling equation for both short blocks and long blocks are defined as Short blocks: img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/0958919.011.png"/ Long blocks: img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/0958919.012.png"/ The denoted scalefactorsscalefactor_sandscalefactor_lused by requantiser are provided by Huffman decipherer.

Reordering This block merely has one undertaking: it reorders the frequence lines within a granule. When the short block is decoded, a short window will be used. The end product is so sorted into subbands, so on frequences and at last by Windowss to increase the efficiency of Huffman coding. img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/0958919.015.png"/ Figure 2.3The reordering procedure ( the darker coloring material represents higher frequences ) Antialiasing Antialiasing is the procedure where its map is to cut down the inevitable assumed name effects because of the use of non-ideal bandpass filtering. The alias Reconstruction is based on the butterfly computation, dwelling of eight butterfly computation for each subband. img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/0958919.016.png"/ Figure 2.4The antialias butterfly Inverse Modified Discrete Cosine Transform Inverse Modified Discrete Cosine Transform, known as IMDCT, reproduce clip samples from the frequence lines, together with synthesis polyphase filterbank. The clip samples can be obtained from the frequence lines by utilizing the undermentioned equation. img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/0958919.017.png"/ The IMDCT operation flow begins by taking 18 input frequence lines and generates 36 polyphase filter subband samples. The samples so multiplied with with a 36-point window before passed into following decryption procedure. Windowing is the procedure of multiplying and overlapping add-on operation of IMDCT’s end product with the sine window coefficient. Based on the length of each window, four types of block is used ; they arestart,halt,shortandlong. The determination of block type is based on the analysis of the psychoacoustic theoretical account. img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/0958919.018.png"/ Figure 2.5Types of window sequences in a subband However, bring forthing 36 samples from 18 input means that there are merely 18 samples are alone, therefore the IMDCT method uses a 50 % convergence. In this instance, the 36 end product samples is so divided into 2 groups, low group and high group, which has 18 samples each. The overlapping procedure is so carried out by adding values from the higher group, old frame with the lower group, matching frame. Then, the frequence inversion is so taken topographic point to accomplish right stage difference. This was done by multiplying every uneven subband with ( -1 ) . img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/0958919.019.png"/ Figure 2.6The IMDCT operation flow Synthesis Polyphase Filterbank This block is the last measure in decrypting procedure.

Contribution Of Ethic Education To Ethical - Myassignmenthelp.Com

Question: Discuss about the Contribution Of Ethic Education To Ethical. Answer: Introduction: Resuscitation, endotracheal intubation (ETI) is an important technique utilized for securing proper passage of airway under pre-hospital emergency settings (Eich et al. 2009). However, lack of regular practise of ETI hampers the competence of the medical nurse to carry-out the ETI process (Kim et al. 2014). Moreover, lack of proper exposure to the ETI process results in high rate of failure. ETI under paediatric set-up is a difficult skill to learn and execute. This is because the anatomy of the pulmonary airway of the children is different from those of the adults and standard adult Macintosh laryngoscope is not suitable for the children (Kim et al. 2014). For children Millers laryngoscope blade is commonly used and these also demands high-end skill. Moreover, through this direct laryngoscopy, it is impossible to visualise the glottis of the child. In order to overcome the limitations video or optical laryngoscopes can be used (Kim et al. 2014). This assignment is important because it aims to provide a detailed critique of a research paper that is based on the intubation under paediatric set-up. The required findings of the study will help in the refinement of the laryngoscope procedure undertaken before ETI for pulmonary airway management. The results will also help to reduce the risks or the chances of failure associated with the process of laryngoscopy among the children. Moreover, the study will help to project a laryngoscopy technique in such a way that it can be easily to conducted by a medical staff without facing much hassle or in-depth requirement of laryngoscope instruments handling skills. Search strategy The review of literature was conducted on the basis of the relevant, authentic and recently published articles. The articles were selected from the electronically from the databases like PubMed and Medline. The main keywords that are employed for the Boolean search of the research articles from the electronic databases include intubation AND laryngoscope, optical laryngoscope AND video laryngoscope, children OR child, paediatric, resuscitation, laryngoscope AND randomized control trial, laryngoscope AND miller laryngoscope, child AND cardiopulmonary resuscitation. Only studies, which are centred on the effect of laryngoscope over the human children during the last 15 years, were chosen for the study. According to the reports published by Parahoo et al. (2006) the selection of the keywords should be done in such a way that it highlights the topic of interest. The research articles which are chosen on the basis of the keyword search are scrutinized on the basis of their abstract in ord er to ascertain the relevancy of the topic discussed in the main body. The detailed inclusion and exclusion criteria, which considered while studying the abstracts, are discussed below. Inclusion criteria Exclusion criteria Studies based on paediatric set-up Studies carried on non-human primates Studies carried on cardiopulmonary resuscitation Studies carried on only human palliative resuscitation Trainee para-medicine health care professionals Experienced healthcare professionals The paper was selected for critical analysis because it compared four commonly used yet popular intubation devices namely McGrath, AirTraq, GlideScope and Miller under a stimulated scenario of paediatric cardiovascular resuscitation. This study thus can effectively be considered as a unique randomized control research in the field of paediatriclaparoscopy. Novel approach and comparative analysis undertaken in this research design further made it unique as no one before conducted this similar kind of study in this field. Moreover, this comparative study helped in the elucidation of the success rate, time requirement and the efficacy of optical or video laparoscope in comparison to the commonly used Millers laryngoscope blade. The results of the study will help in the refinement of the intubation under paediatric set-up. Moreover, the study also aims to decrease the rate of failure or fatal threats associated with laparoscopy before intubation in paediatric conditions thereby helping t o provide quality care to the children. Critique of research rigor The aim of the study undertaken by Szarpak et al. (2015) is to perform a comparative analysis in order to ascertain the efficacy of different available video laryngoscopes with Miller laryngoscope during the emergency intubation required atthe time of paediatric cardiopulmonary resuscitation. The aim of the study is clearly discussed as is extremely relevant in present day scenario. According to Eichet al. (2009), paediatric intubation is a complex skill to learn and demands continuous exposure to the said practise in order to maintain the competence. Leone, Rich and Finer (2005)further opined that lack of practise or exposure results in high rate of failure and this failure rate is independent of the professional background of the intubator. Moreover, paediatric intubation done via using traditional process, Miller's laryngoscope blade, does not enable the intubator to view the glottis of the child clearly (Menges and Crown 2005). On the other hand advanced video laryngoscopes enabl e complete visual coverage of the glottis and thereby aiding to avoid the associated complications of intubation (Kim et al. 2014) Thus the aim of the study conducted by Szarpak et al. (2015) will help to evaluate the efficacy of two techniques underthe parameter of ease of access and efficacy and the subsequent results will help to generate a refined approach for paediatric intubation during cardiovascular resuscitation. The title of the study conducted by Szarpak et al. (2015) says, Comparison of intubation through the McGrath MAC, GlideScope, AirTraq, and Miller laryngoscope by paramedics during child CPR: a randomized crossover manikin trial. Thus the study title of Szarpak et al. (2015) succinctly describes the purpose of the study, methodology undertaken to conduct the study and the chosen group over which the study was designed to be conducted. This kind of formulation of the title by Szarpak et al. (2015) goes in accordance with the concept of research paper published by Parahoo et al. (2006). According to Parahoo et al. (2006), the title of the study must be designed in such a way that it at once gives the important highlights of the study to the readers. An ideal study title must clearly highlights the target group of the study, the aim of the study and the methodological approach (Parahoo et al. 2006). Apart from the study title, the abstract framed by Szarpak et al. (2015) also provide the readers a rough overview of the entire study without any miss of the crucial points. Szarpak et al. (2015) divided the abstract in to four parts including background, methods, results and conclusion. Each part of the abstract is written in a consisted manner, however, not missing any important detail of the study. The framing of the abstract further satisfies the concept opined by Parahoo et al. (2006) in the domain of abstract writing. Determination of the sample size is a crucial part of any research study because sample size helps in determining the significance of the statistical analysis (Suresh and Chandrashekara 2012). The participants of the randomized crossover trial conducted by Szarpak et al. (2015) included the resuscitation trainees of the International Institute of Rescue Research and Education (Warsaw, Poland) who have no known prior experience in the process of paediatric intubation with video laryngoscopes but have previous exposure ro conventional Miller laryngoscope. Szarpak et al. (2015) included total of 102 paramedic trainees.Parahoo et al. (2006) is of the opinion that it is the duty of the researcher to clearly state that number and the nature of the focus group or the sample that has been selected for the study. According to Parahoo et al. it helps in the refinement of the external accuracy of the experiment while retaining the universality of the study. Szarpak et al. (2015) have also docum ented the age, gender, level of education and experience under workplace settings of each of the participants of the focus group separately and have represented the process of sample recruitment via a flow-chart based on CONSORT statement. According to Ross (2012) differential classification of the focus group or the respondents on the basis of their gender and age further helps in the refinement of the data analysis and the obtained results and this in turn help to increase the quality of the study. According to research report published by Parahoo et al. (2006), blinding is acrucial part of randomizedcontrol trial. It is undertaken in order to prevent unconscious and conscious bias. LoBindo-Wood and Haber (2014) further stated that selection of randomization as the main process for conducting a research study is beneficial because randomization helps in the reducing the selection and the confounding bias such that the participants of the study become the true representatives of the selected group of population. Study conducted by Szarpak et al. (2015) selected the candidates for the focus group under strict inclusion and exclusion criteria. This helped to reduce the outcome reporting bias arising out of incomplete reporting while ensuring both representativeness and homogeneity of the sample (Greenhalgh 2014). Selected participants of the study conducted by Szarpak et al. (2015) who have prior experience with Miller laryngoscope were given 45-minute training on anatomy of the p aediatric respiratory system and techniques employed in video laryngoscopes. After training with each device of the video laryngoscopes, participants were allowed to take a 20-minute rest followed by intubation test. In order to avoid observation based learning effect, participants were not allowed to view each other during the time of the test.According to Greenhalgh (2014), this approach furnishes two different meaning of ascertaining the outcomes that arecapable of reducing the chance of bias while increasing the accuracy of the findings.The demographic of the participants were kept identical in terms of experience and this gain helps in the improvement of the overall accuracy of the outcomes (Parahoo 2006). Ross (2012) further opined that accuracy and dependability of tests could be increased via proper handling of the participating individuals in an identical manner. This helps in decreasing the influence of confounding variables. However, Szarpak et al. (2015) did not mentione d that whether the participants were completely blinded about the aim of the study while they are asked to filled a questionnaire about their experience while taking the test. According to Greenhalgh (2014), blinding of the participants of the focus group help in the reducing the bias effect of the study. The exclusion-inclusion criteria of prospective focus group selection were clearly stated in the study. The study here excluded women who are suffering from diabetes, preeclampsia, obesity, hypertension and multiple pregnancies. According to Ross (2012), the criteria of inclusion and exclusion must be stated clearly. Greenhalgh (2014) further opined that determination of these guidelines helps to increase the accuracy of the study. The study of Szarpak et al. (2015) observed proper ethical regulations that are required to carry out randomize control study (Thompson et al. 2006). Szarpak et al. (2015) haveincluded the participants of the study only after taking a written consent from all the 102 participants. Required approval from the concerned authority was taken over the randomised crossover trail design of the study before initiation. The aim of the research satisfies the ethical principal of non- malfeasance which states that the healthcare professionals must not provide ineffective treatment that has chances to harm the patients (Parahoo 2006). Szarpak et al. (2015) used R statistical package for Windows and the obtained results were represented via mean standard deviation or absolute percentage or numbers. Wilcoxon signed rank test was again used to verify the results. McNemar test was employed to analyse the possible difference in the success rate of the study and multivariate regression analysis models were employed to analyse the impact of age, sex, work-experience and education level over the efficacy of the blind intubation. P value of less than 0.5 was considered to be statistically significant.Ross (2012) stated that use of more than one statistical tests is helpful to comparison the results in order to evaluate the significance. According to Parahoo (2006), it is the duty of the researcher to discuss the limitations of their own study. Szarpak et al. (2015) highlighted Manikin approach as the main limitations of their study this is because Manikin studies can never fully substitute the studies carried over the human models. Moreover Szarpak et al. (2015) stated that the intubation devices used have not been compared under the situation of randomized, crossover and controlled trial. Study Findings and Physiological Implications of the Study The results of the statistical analysisperformed by Szarpak et al. (2015) showed that the success rate of the endotracheal intubation (ETI) video laryngoscopes was higher than direct laryngoscope done via using Miller Laryngoscope. The statistical significance of AirTraq, GlideScope and McGrath in comparison to Miller Laryngoscope include P The guidelines of the European Resuscitation Council (2010) emphasizes the delivery of continuous compression of chest within a few interruptions as possible encompassing frequent break for airway management efforts. An airway management effort is considered to be an essential factor in both pre-hospital and in-hospital paediatric intubation. However, intubation is a technically challenging skill to learn and demands continuous exposure to the process in order to prevent the deterioration of the skill Hubble et al. (2010). Here lies the main physiological implication of the study as it helps in the elucidation of a new yet innovative technique for paediatric intubation. Video (McGraph or GlideScope) or optical laryngoscopes (AirTraq) is easy to operate under paediatric set-upand does not demands regular practise to prevent skill deterioration and is quick to execute (Szarpak et al. 2015).According to Manica et al. (2013) prolong length of the intubation done via the use of the tradit ional laryngoscopes results in the development of the laryngeal lesions along with the increase in the incidence of subglottic stenosis. Thus application of the video or optical laryngoscopes will help to reduce the chance of developing paediatric complications during intubation. Moreover, according to Fiadjoe et al. (2016), direct yet prolong laryngoscope procedures in paediatric set-up is associated with numerous complication and thus proper assessment of the larynx via video laryngoscope and then triggering the intubation will help to avoid complications under paediatric set-up. According to European Resuscitation Council (2010), team of nurse who are under the resuscitation team should be concerned in ensuring the safety of the patient. The ground of patient safety and subsequent comfort falls under the principal duty of the nurse operating the patient. According to Hazinski (2012), it is the duty of the nurse to assure the comfort and the safety of a child during any form of treatment as children are unable to express their sense of discomfort clearly. Hence forming intubation via video or optical laryngoscope will help to reduce the discomfort of the children. Moreover, according to the reports published by Szarpak et al. 2015, video laryngoscope is fact and accurate technique and thereby further helping to reduce the children level of discomfort. The use of the optical or video laryngoscope goes in favour of the ethical principle of beneficence and non-malfeasance (Cannaerts, Gastmans and Casterl 2014). According to the ethical principle of beneficence, it is the duty of the healthcare professionals to provide maximum benefits to their clients and thereby contributing health and well-being (Cannaerts, Gastmans and Casterl 2014). The reports published by Szarpak et al. 2015 revealed that video or optical laryngoscopic technique is more superior to the Millers laryngoscope blade as it is fast and helps in the proper view of the glottis and hence reducing the complications of intubation and thus providing comfort and benefit to the child. The use of optical or video laryngoscope technique also goes in accordance to the ethical principle of non-malfeasance, which promotes obligations towards intentional harm (Cannaerts, Gastmans and Casterl 2014). Conclusion Thus from the above critical analysis of the research paper published by Szarpak et al. 2015 it can be concluded that optical or video laparoscopy is one of the best suited methodsduring the emergency situation in hospitals. It can be considered as a safe and alternative for other conventional method used for paediatric endotracheal intubation (ETI). Thestudy further stated McGrath, GlideScope, and AirTraq intubation devices are fast, safe, and easy to use. The use of the optical or video laryngoscope technique does not cast any intentional harm to the child on contrary it helps to undertake refinement of the intubation technique, reducing the childs harm from the long-term therapy. Thus the study eliminates the requirement of expertise skills and regular practise of laryngoscopy by the medical staffs in order to avoid unsuccessful cases of ETI. Moreover, different laryngoscope approach is required for children because of the different anatomical of the childrens throat in comparison to that of the adults. Millers laryngoscope fails to view the glottis of the children clearly. The use of video laryngoscope will promote clear view of the glottis of the child and thus eradicating the complications arising out of prolong intubation. Within the stated limitations of a randomized manikin study, this researchproposes that inexperienced healthcare professionals might earn certain benefit from using video laryngoscope devices during emergency airway management of a child. However, it must be taken into consideration that endotracheal intubation (ETI) must be preferably done under the controlled supervision of the experienced physicians and paramedics. The study is unique in the domain of paediatric intubation and proposed advancement in this domain. The study scores high in the grounds of title formation, compact abstract framework, selection and elaboration of sampling methods, statistical analysis and elimination of the confounding bias. However, study could not high light that whether the participants were aware about the aim of the study as this may also impose a bias effect on the end results.
