Purpose: This study performed the descriptive analysis of commercial seasonings and the correlation between electronic nose analysis and electronic tongue analysis. Methods: This study was performed to analyze descriptive analysis by principal component analysis (PCA). Further, the relationship between characteristics determined by electronic nose analysis and sensory characteristics, as well as the relationship between characteristics determined by electronic tongue analysis and sensory characteristics were by Pearson"s correlation analysis and partial least square regression (PLSR) analysis. The study was conducted with 10 trained panelists, and eight kinds of seasoning samples were used. Results: During the descriptive analysis period, a total of 40 descriptive attributes were developed. Descriptive expressions of the commercial seasonings include six appearance characteristics, 12 odor / flavor characteristics, 13 taste characteristics, four after-taste characteristics, and five mouth feeling characteristics. Descriptive analysis characteristics of commercial seasonings were clearly distinguished based on the main characteristics, product type, and additives, and samples of meat, seafood, and fermented soybeans. The electronic nose scent pattern was largely divided into liquid product and powder product. Based on the descriptive analysis, electronic tongue analysis was distinguished from bitter taste and sour taste. Conclusion: Some of the correlations between human senses, electronic nose and electronic tongue sensors were confirmed. In the correlation analysis between descriptive characteristics, electronic nose analysis, and electronic tongue analysis, the tendency between samples, sensory characteristics, and sensors was classified. This study can be used not only as useful data on sensory quality of domestic seasonings but also in future seasoning development.

문헌정보학분야에서 메타분석 연구에 관한 고찰

노정순 한국문헌정보학회 2008 한국문헌정보학회지 Vol.42 No.1

Meta-analysis refers to the analysis of analysis. It is the statistical analysis of a large collection of analysis results from individual studies for the purpose of summarizing, integrating and interpreting the inconsistent findings. However, no meta-analysis study has been conducted in Library and Information Science in Korea. This Study introduced the charactersistics, basic principles, analysis procesure, and major models of meta-analysis, reviewed meta-analysis studies in Library and Information Science, and discussed major problems in conducting meta-analysis in Library and Information Science especially in Korea. 메타분석(Meta-Analysis)이란 분석에 대한 분석(analysis of analysis)이란 의미로, 특정 연구문제에 대해 독립적으로 수행된 선행연구들의 일치하지 않은 결과들을 통합하여 결론을 내리기 위해 개개 연구의 분석결과들을 수학적으로 합성하여 통계적으로 결론을 내리는 방법이다. 본 연구는 메타분석의 특성과 기본 원리, 분석 절차, 대표적인 분석모델을 소개하고, 문헌정보학분야에서의 메타분석연구를 고찰하였다. 다른 학문에 비해 문헌정보학에서 메타분석연구는 매우 소량 수행되었고 국내 문헌정보학분야에서는 전무한 상태이다. 문헌정보학에서 메타분석을 수행하는데 문제점과 메타분석연구를 활성화하기 위해 연구자가 보고서 작성시 유의해야 할 내용을 논의하였다.

Analysis of Research Trends in South Korean ODA for Ethiopia (2000-2015)

Kim HyunJae,Shon Mi,Kim YoungHwan,Park MinKyoung APEC국제교육협력원 2015 Asia-Pacific Cybereducation Journal Vol.11 No.2

The purpose of this study is to analyze the research trends in the South Korean Official Development Assistance (ODA), by examining the papers of degree thesis papers, project reports, and academic journals published from 2000 to 2015, as well as investigating and proposing the themes for future studies. According to the rubrics of analysis, from numerous papers, twelve thesis, twelve reports and eight academic journals were selected and considered following five analysis criteria; namely, published year, stakeholder of study, project procedure, methodology, and relevance to MDGs, the Millennium Development Goals. The results of the analysis are as follows: first, the papers associated with South Korean ODA for Ethiopia were published in 2008 for the first time. With steadily increasing numbers of thesis, reports, and journals, following after 2008, researches have conducted studies vigorously since 2011. However, investigations on the South Korean ODA for Ethiopia are noticeably insufficient, in comparison to the grant aids and concessional loans paid thus far. Secondly, the analysis appeared in twelve papers published by universities, eleven by government authorities, and eight by specialty magazines. Upon closer inspection, the government authority indicated Korea International Cooperation Agency (KOICA), and eight other specialty magazines, as well as the following: Korea Water Resources Association2), Korean Association of African Studies3), Korea Society of Agricultural Extension4), Korean Journal of Health Education and Promotion5), Journal of International Collaboration in Education6), Korea Research Society for Customs7),Perspectives in Nursing Science, The Women’s Studies8). Third, project procedure utilized as the criteria for the analysis. As a result, one feasibility study conducted in 2012 and 2013, one planning study in 2008 and 2010, two planning studies in 2013, one evaluation study in 2011 were identified. However, each project procedure paper for the 25 projects launched thus far were difficult to find. Papers for those have no relevance with ODA projects, and were considered as other studies. Fourth, papers relevant to the MDGs stand as such; 11 papers were linked with MDG 2, ‘Achieve universal primary education’. Three papers had relevance to MDG 1, ‘Eradicate extreme poverty and hunger’, one to MDG 3, ‘Promote gender equality’, three to MDG 5, ‘Improve maternal health’, four to MDG 6, ‘Combat HIV/AIDS malaria, and other diseases’, two to MDG 7, ‘Ensure environmental sustainability’, seven to MDG 8, ‘Develop a global partnership for development’. There were no papers connected with MDG 4, ‘Reduce child mortality’. Therefore, based on this trend analysis, broader spectrums and diverse methods of study should be implemented for the future studies with regard to the South Korean ODA for Ethiopia.

Independent Component Analysis를 이용한 fMRI신호 분석

문찬홍,나동규,박현욱,유재욱,이은정,변홍식 대한자기공명의과학회 1999 Investigative Magnetic Resonance Imaging Vol.3 No.2

fMRI의 신호는 매우 다양한 종류의 선호들이 혼합된 상태이며 , 비록 몇 가지의 요소에 대해 모델링하여 그 선호 형태를 추측할 수 있으나 모든 신호를 정확하게 분리하여 뇌신경의 활성화를 반영하는 신호만을 선택적으로 알아 내기는 어려운 일이다. 또한 뇌와 신체의 생리적 현상으로 발생하는 잡음뿐아니라 움직임이나 계기의 잡음은 fMRl의 데이터 분석을더욱 어렵게 한다. 따라서 실제 뇌신경의 활성화를 정확히 나타내는 참고데이터(reference data)를 선택하는 것은 힘든 일이며, 뇌신경의 활성화를 반영하는 의미 있는 여러 신호 형태에 대한 분석은 현재 fMRl의 후처리 (post-processing) 분석 방법에서 하나의 연구 과제라 할 수 있다. 본 연구에서는 prioriknow­-ledge 혹은 참고 데이터가 필요 없는 분석 방법인 Independent Component Analysis (lCA) 를 이용하여 fMRI선호를 분석하였다. ICA는 현재 많이 사용되고 있는 상관 분석 방법에 비해 신호의 형태를 분석하는 데에 보다 효과적일 수 있으며, 지연된 반응 형태를 갖는 신호나 움직임에 의한 신호의 패턴을 분리하여 분석할 수 있다. 한편, ICA만으후 fMRl의 신호에 따라 분석이 효과적이지 못한 경우 Principal Component Analysis(PCA) threshold, wavelet spatial f filtering, 부분적 영상 분석 방법들을 ICA전에 수행 함으로써 보다 효과적인 분석을 수행할 수 있다. ICA는 fMRl 신호의 형태 분석에 효과적인 방법이라고 생각하며, 데이터의 자유도를 감소 하기 위해서는 선 필터링 (pre-filtering) 방법들이 적용될 수 있다. The fMRI signals are composed of many various signals. It is very difficult to find the accurate parameter for the model of fMRI signal containing only neural activity, though we may estimating the signal patterns by the modeling of several signal components. Besides the nose by the physiologic motion, the motion of object and noise of MR instruments make it more difficult to analyze signals of fMRI. Therefore, it is not easy to select an accurate reference data that can accurately reflect neural activity, and the method of an analysis of various signal patterns containing the information of neural activity is an issue of the post-processing methods for fMRI. In the present study, fMRI data was analyzed with the Independent Component Analysis(ICA) method that doesn't need a priori-knowledge or reference data. ICA can be more effective over the analytic method using cross-correlation analysis and can separate the signal patterns of the signals with delayed response or motion related components. The Principal component Analysis (PCA) threshold, wavelet spatial filtering and analysis of a part of whole images can be used for the reduction of the freedom of data before ICA analysis, and these preceding analyses may be useful for a more effective analysis. As a result, ICA method will be effective for the degree of freedom of the data.

한국 미술계 위작(僞作)·대작(代作)에 대한미디어 담론 분석- 프레임 네트워크 분석 접근법

양희수,현은정 한국예술경영학회 2018 예술경영연구 Vol.0 No.45

Prior research suggests that media discourse affects the behavior and outcomes of relevant actors. In particular, media discourse analysis using text network analysis has been increasingly used to capture the structural properties of contentious social issues across various fields. The use of this method, however, has not been very active among researchers of arts and culture. In this paper, we present an analysis of media discourse related to art forgery in the Korean visual art sector as a test case to depict the topography of media discourse through text network analysis. We focus on three major art forgery scandals (e.g., Lee Woo Hwan, Chun Kyung ja, Jo Young Nam) and identify 8 major frames (conflict, blame attribution, context description, sensation, government intervention / institutional measures, market economy, power, morality) used in 83 opinion columns in the Korean daily newspapers as well as arts magazines about those instances from 1991 to 2017. We examine how theses frames that reflect the perspectives on art forgery are connected to one another so as to better make sense of how media discourses about art forgery in the Korean visual art sector are constituted. 미디어 담론(media discourse)은 행위자들의 행동과 결과에 영향을 미친다는 점에서 중요한 의의를 가진다. 특히, 네트워크 분석(network analysis)을 이용한 미디어 담론 분석은 다양한 분야에서 논쟁이 되고 있는 사회적인 이슈의 구조적 특성을나타내기 위해 사용되어 왔다. 하지만, 문화예술연구에서 네트워크 분석(network analysis)은 비교적 새로운 분석 방법으로, 최근 들어 문화예술분야의 연구 동향을나타내기 위한 분석 방법으로 사용되고 있다. 본 논문은 네트워크 분석(network analysis)을 통해 미디어 담론(media discourse)의 지형을 나타내기 위한 사례로서, 한국 미술계의 위작(僞作), 대작(代作)사건과 관련된 미디어 담론(meida discourse) 을 ‘프레임(frame)’을 중심으로 분석한다. 구체적으로는 한국 미술계의 위작(僞作), 대작(代作)논란을 다룬 사설·칼럼 83개를 대상으로 11개의 프레임(frame)을 부여하고, 11개의 프레임(frame)들을 대상으로 네트워크 분석(network analysis) – 1) 11개 프레임(frame)간의 관계를 파악하기 위한 중심성(degree centrality, eigenvector centrality), 등위성 분석(cluster) 2) 미디어 매체(media)의 이데올로기적 성향(ideological tendency)별로 11개 프레임(frame)에 대한 연결 중심성 분석(degree centrality analysis) –을 실시하였다. 이를 통해 미디어 매체(media)가 미술계의 위작(僞作), 대작(代作)에 대해 전체적으로 각 사건들에 대한 사실·갈등 양상을 나열하거나, 각 사건의 행위 주체의 책임을 묻는 등의 프레임(frame)을 중점으로 담론(discourse)을 형성하였음을 알 수 있었다. 이와 더불어 미디어 매체(media)의 이데올로기적 성향(ideological tendency)에 따라 한국 미술계의 위작(僞作), 대작(代作)논란을 바라보는 시각에 차이가 존재함을 알 수 있었다. 이와 같은 분석결과를 통해, 본 연구는 문화예술분야에서 비교적 새로운 분석 방법인 프레임 분석(frame analysis)을 통해 국내 미술계의 위작(僞作)·대작(代作)논란에 대한 미디어 담론(media discourse)을 파악하고, 이를 네트워크 지도(network map)를 통해 시각화하였다는 시사점을 가진다. 또한, 11개의 프레임(frame)을 대상으로 실시한 네트워크 분석(network analysis)을 통해 미술품 위작(僞作)·대작(代作)을 둘러싼 미술계 외부와 내부의 견해차를 확인함으로써, 향후 정부 부처가 이와 관련한 정책을 도출하는 과정에서 본 논문이 실증적 자료를 제공하는 것에 그 의의가 있다.

As a network analysis tool, ‘UCINET’ was used the most, and the most studies that visualized the results through a network map were the most. In all 28 papers to be analyzed, the centrality scale was used as an analysis index, and methods such as clustering and ego network analysis were also used. Conclusions These results have significance in providing a direction for conducting language network research in the field of special education in the future, and the need for continuous expansion of qualitatively more diverse topics, as well as network analysis tools, visualization presentation methods, and analysis suitable for research purposes and topics. The necessity of presenting the research results abundantly using indicators was suggested.

뉴스 빅 데이터에 나타난 ‘독서’ 담론 분석 : 11개 중앙 일간지를 중심으로

신선주 ( Shin¸ Seonju ) 한국독서학회 2020 독서연구 Vol.0 No.57

본 연구는 뉴스 빅 데이터 분석시스템 ‘빅카인즈(BigKinds)’에 나타난 ‘독서’ 담론이 무엇인지 알아보기 위해 정부가 추진하고 있는 ‘독서문화정책’시행 원년인 2009년을 분기점으로 이전 10년(1999년~2008년)과 이후 10년(2009년~2018년)으로 나누어 독서담론이 어떻게 나타나고 있는지 분석하고자 하였다. 또한 빅카인즈를 활용한 4가지 분석기법(키워드 검색, 연도별키워드 트렌드, 관계도 분석, 연관어 분석)을 통해 시기별 독서담론에서 어떤 지배적 담론이 들어가 있는지를 알아보기 위해 각 단계별 분석과정에서 나타나는 특징들을 대상으로 ‘독서’와 관련된 사회적 현상과 지배적인 독서담론을 들여다보고자 하였다. 연구 결과 다음과 같은 분석결과를 나타냈다. 첫째, 1999년부터 2018년까지 11개 중앙 일간지에 나타난 ‘독서’ 키워드의 기사가 갖는 독서담론의 비중을 확인한 결과 1차시기(1999~2008)에 비해 2차시기(2009~2018)의 키워드 추출 건수는 증가하였으나, 전체 기사 게재율 대비‘독서’키워드 추출건수 비율은 1,2차시기 모두 0.4%로 동일하게 나타났다. 이는 일간지에서 다루는 ‘독서’ 담론이 아주 미비함을 뜻하며, 뉴스기사에서 다루는 비율도 정부가 적극적으로 추진하는 ‘독서문화진흥정책’에 비해 지난 20년간큰 변화가 없음을 보여주었다. 둘째, 11개 중앙 일간지에 나타난 ‘독서’ 키워드 트렌드 분석 결과 ‘독서’가 다른 사회적 이슈들에 밀려 다뤄지지 않는 키워드에 속했으며, 일부 트렌드 추이가 올라가는 부분의 독서분야 이슈들을 살펴보면 정부가 추진하는 정책과 뉴스기사에서 다뤄지는 토픽과 밀접한 관련이 있음을 알 수 있다. 이는 ‘독서’가 개인의 담론으로는 한계점을 가지고 있으며, 정부가 적극적으로 정책적 이슈를 이끄는 것이 사회적인 독서담론에도 영향을 미치는 것으로 나타났다. 셋째, ‘독서’ 관계도 분석과 연관어 분석은 1,2차 시기별로 큰 차이를 보이지 않았다. 다만 정부나 민간이 추진하는 독서관련 사업에 따라 관계도와 연관어 분석에서는 키워드 빈도에서 약간의 변화가 있을 뿐이었다. 마지막으로 본 연구에서 제한점은 주제별 토픽분석기법인 ‘LDA’를 활용해서 토픽구조분석을 실시해야 했으나 실행하지 못함으로써 키워드 분석 중심으로 ‘독서’담론을 들여다보는 데 그쳤다. 또한 뉴스기사의 담론분석은 사회적 이슈가 큰 분야에서 보다 유용하게 분석을 이끌어낼 수 있다는 점과 ‘독서’와 같이 사회적 이슈가 적은 분야에서는 이슈분석보다 정부의 독서정책과 방향에 대한분석에 초점을 맞추는 것이 독서현장의 실행력을 높이는 데 더 주요한 연구가 될 것으로 생각된다. In 2009, the “Reading Culture Policy” was implemented in X, promoted by the Government. This study addresses the ten years before (1999-2008) and after (2009-2018) and analyzes how the reading discourses in each period appear to investigate the “reading” discourses in “Bigkinds,” a news-based big data analysis system. Further, the study investigates, by stage, the social phenomena related to “reading” for the characteristics in the analysis process. It also identifies the dominant reading discourses by period, through four analysis techniques (Keyword search, keyword trend by year, relationship analysis, and related word analysis), utilizing “Bigkinds.” Through this analysis, the following results were obtained. The importance of the reading discourses was examined by identifying articles containing the keyword “reading” in 11 major daily newspapers from 1999 through 2018. More articles were identified in Period 2 (2009- 2018) than in Period 1 (1999-2008), but, as a percentage of the total number of articles, the occurrence of the keyword “reading” remained the same (0.4%). This means that “reading” discourses infrequently feature in daily newspapers. Despite the “Reading Culture Promotion Policy” being actively promoted by the Government, their frequency of occurrence in news articles has remained largely unchanged for the past20 years. Second, analysis of the trend of the keyword “reading” in these 11 major daily newspapers revealed that it was not dealt with behind other social issues. Examining the issues in the field of reading during the period in which there was an increase in the trend revealed that they had close relationships with policies promoted by the Government and with the topics dealt with in the news articles. This shows that “reading” has a limitation as an individual’s discourse and that the Government’s active leading of policy issues affects social reading discourses. Third, relationship analysis (and related word analysis) concerning “reading” revealed that there was no significant difference between Periods 1 and 2. However, there was a slight change in the frequency of the keyword in the relationship and related word analysis, according to whether the reading-related projects were promoted by the government or the private sector. One limitation of this study is that topic structure analysis was not conducted utilizing “LDA,” a topic analysis technique. Rather, this study solely examined “reading” discourses, focusing on keyword analysis. Furthermore, analysis of the discourses of news articles could draw a more useful analysis in the areas that have more social issues. Additionally, focusing on the analysis of the Government’s reading policies and directions in areas that have fewer social issues would be more important regarding increasing executive ability in the field of reading.

On the Relationship between ??-sensitivity Analysis and Sensitivity Analysis using an Optimal Basis

Park, Chan-Kyoo,Kim, Woo-Je,Park, Soondal 한국경영과학회 2004 Management Science and Financial Engineering Vol.10 No.2

e-sensitivity analysis is a kind of methods for performing sensitivity analysis for linear programming. Its main advantage is that it can be directly applied for interior-point methods with a little computation. Although e-sensitivity analysis was proposed several years ago, there have been no studies on its relationship with other sensitivity analysis methods. In this paper, we discuss the relationship between e-sensitivity analysis and sensitivity analysis using an optimal basis. First, we present a property of e-sensitivity analysis, from which we derive a simplified formula for finding the characteristic region of e-sensitivity analysis. Next, using the simplified formula, we examine the relationship between e-sensitivity analysis and sensitivity analysis using optimal basis when an e-optimal solution is sufficiently close to an optimal extreme solution. We show that under primal nondegeneracy or dual nondegeneracy of an optimal extreme solution, the characteristic region of e-sensitivity analysis converges to that of sensitivity analysis using an optimal basis. However, for the case of both primal and dual degeneracy, we present an example in which the characteristic region of e-sensitivity analysis is different from that of sensitivity analysis using an optimal basis.

이인모,안대진 사단법인 한국터널지하공간학회 2001 한국터널지하공간학회논문집 Vol.3 No.4

Generally, it has been noted that underground structures have a consistent record of suffering much less damage thansurface facilities during earthquakes; but it is still necessar subject to earthquake loadings and to provide the appropriate m ethod for the seismic analysis of underground tunnelstructures since many types of underground structures have been and will be constructed in countries situated withinground tunnel structures are performed by using quasi-static analysis method and dynamic analysis method. Second, se ismic analyses in tunnel portals are performed by usingabove methods. The results of seismic analyses for the tunnel s tructure show that the tunnel structure conforms toground deformation and that seismic design by using the quasi-s tatic analysis method is more conservative than that byusing the dynamic analysis. The results of the dynamic FEM anal ysis for the tunnel structure show that the simplified 2-is can be adopted for seismic analysis. Finally, theresults of the dynamic FEM analysis in tunnel portals show that the force acting on the lining is largest near to thetunnel portal when an earthquake wave propagates parallel to tu nnel axis.

법조인 선발제도별 비용분석과 진입유인 분석

천도정 ( Do Jeong Cheon ),황인태 ( In Tae Hwang ) 한국회계학회 2016 회계저널 Vol.25 No.4

본 연구의 목적은 기존 사법시험이 갖는 소위 ‘고시낭인’이 되어 역기능으로서 사회가 부담하고 있는 사회적비용을 감소시키고 법조인의 다양성과 전문적 지식을 법에 도입하기 위한 제도로서 법학전문대학원(law school; 로스쿨: 이하 ‘법전원’)이 갖는 장점에도불구하고 법전원의 고비용구조가 우리 국민 모두가 진입할 수 있는 법조영역에 대한 진입장벽이 되어 특정 소득계층이 진입하지 못하는 문제가 과연 존재할 수 있는지의 여부를 분석하고자 하는데 있다. 법전원이 출범했음에도 불구하고 지금까지 구체적인 분석이 이루어지지 않고 막연한 추측과 여론에 의하여 고비용구조이기 때문에 법조인이 되는데 진입장벽이 되고, 오히려 기존의 사법시험을 존치하여 문제를 해결하여야 한다는 주장이 많이 제기되고 있는 실정이다. 현재 국회에는 김용남 의원 등이 발의한 사시 존치 관련 법안 4건이 계류되어있다. 여기에 오신환 의원이 대표발의한 사시 존치 법안이 지난 6월 제출되어 법안소위 회부를 기다리고있는 상태다. 그러나 기존의 사법시험과 비교하여 얼마나 많은 비용차이가 발생하는지 구체적인 분석은 이루어진 적이 없다. 본 분석의 목적은 기존 사법시험제도와 법전원체제에 대한 가치판단의 문제에 대한 접근은 제외하고, 순수한 비용분석에 의하여 국민소득계층에서 법조계에 진입하지 못하는 소득계층이 존재하는지 여부를 비교분석하는데 있으며, 만일 존재한다면 어떠한 계층이 진입할가능성이 적은지를 분석하였다. 이러한 분석은 국민의 교육과 직업기회에 대한 형평성과 법조분야의 발전에 매우 중요한 의미를 갖는다고 할 수 있다. 따라서 본 비용분석은 법전원 출신의 변호사시험과 기존 사법시험과의 분석에서 측정 불가능한 요인은 배제하고, 측정 가능한 범위 내에서 비용의 총액과 차액분석을 통하여 비교하고, 법조인이 되기 위한 기회비용을 이용하여 비용의 차이를 비교 분석하여 소득계층의 진입가능여부의 판단기준을 제시한다는 것은 원가(비용)분석의 사례로서 큰 의미가 있다고 생각한다. The goal of this cost analysis is to explore and analyze, despite the advantages the new ``law school`` system, which reduces the social costs of the ‘entrance exam vagabond’ problem by solving this social issue the previous judicial bar entrance exam had, and allows the for the diversification of the pool of applicants and encourages professional knowledge in the law industry, if in fact there is a possibility that the cost structure of law school serving as an entrance barrier for certain socio-economic groups to apply to be a Judicial Officer is a problem that exists. Even though the law school system was established, there has not yet been a detailed analysis, and the reality is that through vague guesswork and media spin, the system is blamed as being of high cost and therefore the cause for being a high barrier of entry to certain socioeconomic classes to become a Judicial Officer, and that it also retains the problems of the previous judicial bar examination, so there are many opinions that these problems of the new law school system need to be solved. However, there has yet to have been a detailed cost comparison analysis to explore how much the cost difference is with the old judicial bar examination system. The goal of this analysis is in the case where the previous judicial bar examination has been abolished and the law school system goes into full effect, excluding the qualitative comparison of which selection process is more practical in turning out Judicial Officers, to evaluate from a strictly cost analysis point of view whether the law school system serves as a barrier of entry to any socioeconomic group. And if in fact this barrier exists, to analyze which socioeconomic group has the least chance of being able to enter. Such analysis can be seen as having significant meaning in supporting the fairness of Korea’s education system and job opportunity system and also the advancement of the Judicial Officer selection and law industry. Therefore, this study excludes any elements in the current law school entrance exam system and the previous judicial bar examination system that cannot be accurately quantified, and compares the two systems within the bounds of quantifiable ranges, such as the analysis of the total and differential costs, and also the opportunity cost of becoming a Judicial Officer. All these factors are used for comparative analysis, and to present an official set of criterion that can be used to predict the chance of a certain socioeconomic group being successfully selected as a Judicial Officer has significant meaning as a case study of cost analysis. If the law school system continues, a phenomenon in which the entry of individuals into legal circles is determined according to their economic income quantiles will set in. Therefore, various reviews on the lawyers training system should be performed. In relation to the costs of training lawyers, critics about the national judicial examination point out the seriousness of the problem of social opportunity costs due to numerous “unemployed individuals produced after failing in the examination” because the acceptance ratio remains at 3%. The costs borne by examinees who prepare for the existing national judicial examination are explicit costs that are borne by the examinees themselves. As they are willing to pay the costs, these costs can be viewed as avoidable costs. However, the costs borne by examinees for law schools are imputed costs under a system, and therefore, are more of unavoidable costs. Operating costs borne by universities to operate law schools, and scholarships and other costs borne by universities to meet the conditions required to operate law schools are indirect costs, and thus, these may be categorized as indirect opportunity costs borne by society. In addition, we should be aware that if the bar examination following the law school system continues to be operated for a long time, opportunity costs incurred by declines in the acceptance ratio should be borne. This study conducted an analysis that is limited to the analysis of costs that will actually be incurred or are projected to be incurred while excluding overall axiological judgements on the lawyers training system or discussions on the appropriateness of the system. Therefore, it should be noted that there can be a number of variations according to circumstantial changes. However, there was a limitation in the cost analysis. For example, the operating costs of law schools borne by universities and implicit social indirect costs were excluded from the analysis because it was actually impossible to obtain data on these costs or measure them.
