The classification systems generally used in library are for the external information such as books and periodicals, so it is difficult to apply them to the internal information of specific organization such as documents and records. Therefore, it is necessary for the information centers of any enterprise or specific organization to found the Record Management System (RMS), and to develop and use the specific classification system which is called the coding system for internal information. Documents and components of nuclear power plant are controlled by coding (numbering) system, but they are different each other greatly. So the coordination of work and the cross reference between components and documents are difficult. In this paper, the unified Record Management Coding System is developed for Nuclear Power Plant unit 7 & 8 in Korea on the basis of the existing document and component coding system. The expected effects are the easy cross reference between components and documents, the effective coordination of work and the consistence of central file.

The purpose of this study was to explore and better understand special education music teachers' perceptions of their music curriculum. For this purpose, we conducted a focus group interview with seven special education music teachers. During the interview, four major themes and 14 sub-themes were identified. The main themes were the following: (a) types of applied activities and the goals of music classes (e.g., activities to be applied in various ways depending on the characteristics of the disability and intended outcome), (b) difficulty in implementing the music curriculum (e.g., lack of fit between textbook and students' chronological ages, lack of time and focus, self-evaluation of performance as a music teacher, (c) therapeutic experiences during music classes (e.g., expectation for positive effects through music therapy, joy of witnessing changes in students, and sense of togetherness), and (d) obstacles to the therapeutic approach of music classes and need for support (e.g., lack of professional knowledge regarding therapeutic approaches and problems with administrators and school environment). Based on these results, problems in implementing the music therapy approach as part of the music curriculum in special education schools are discussed and practical solutions for educators are offered.

New education methodologies exploiting new media technologies are emerging with the development of digital technology. There also have been researches on efficient methods to apply new technologies on special education. In this paper, we analyze 32 researches associated with application of new media technology on special education for research theme, media, and teaching types. The analysis results show that there is few research on intervention contents which consider special education environment and the roll of teacher. This motivates us to develop a social storytelling contents to improve sociality of the children with developmental disability which can be easily useable in special education environment. The basic structure of the contents is designed for a child to make a choice in the meantime of storytelling and experience the different results depending on the choice. The pilot test with a child with mild autism verifies that it draws attention from the child and it is easy to use in a special education environment, which lays down the possibility as an intervention content.

The purpose of this study is to confirm the definition and the scopes of the implementation of Korean education for missionary purposes which is an area of ones for specific purposes and to suggest the teaching methods for each type by examining the subtypes of it. For this, a body of research and the related textbooks were analyzed: as a result, the definition of Korean education for missionary purposes was confirmed by examining the scope of implementation of it. Based on the definition, this study categorized the learners into four patterns such as non-Christian, the learners for listening gospel, the learners for nurturing, overseas Korean children and missionary kids according to the levels of Christianity literacy and briefly proposed the goals and teaching methods for each category. Finally, this study expected the development of the related textbooks and the activation of more segmented research in this area.

The aim of this study is to reveal errors in the estimations on the nonstandard workers scale which have resulted from little consideration for bogus self-employment. Bogus self-employment means disguised employment relationships that are considered to be self-employed workers even though they have inherent subordination. The methods of previous studies estimate that the bogus self-employed workers are excluded from estimations because they are not workers in principle. We analyze the scale of the bogus self-employments using the empirical data [the Korean Welfare Panel of 2008-2013(six wave panel)] to re-estimate the scale of non-standard workers. In 2013, the year of the last wave, the percentage of the bogus self-employment was high, the proportion of them is 28.5% among self-employment without owning a place of business. Our results expect the number of contract workers from re-analysis would be over 740 thousand when reflecting on the predictive value in the actual number of paid workers. In conclusion, it is necessary to apply reasonable methods of analysis concerning the scope and scale of the nonstandard workers for the sake of coping with measures against the problem of nonstandard workers. The aim of this study is to reveal the estimation error on nonstandard workers' scale which are resulted from having no consideration for bogus self-employment. Bogus self-employment means disguised employment relationship that is considered as self-employment workers even though they have inherent subordination. The methods of previous researches' estimation on nonstandard workers have the problem that the bogus self-employment workers are excluded from estimation because they are not workers in principle.

The purpose of this study is to analyze regional clusters and discrimination on size and sector of private security in national 16 areas in 2015. The results of the study using hierarchical cluster analysis and discriminant analysis are as follows. First, we can classify national 16 areas into 3 clusters, such as Large Area(1), Medium Area(2), and Small Area(3) according to the size of private security. The discriminant functions D for each cluster is as follows: (1) Large Area(1) = -383.981 + (.108 ${\times}$ number of security companies) + (.016 ${\times}$ number of guards), (2) Medium Area(2) = -35.570 + (.029 ${\times}$ number of security companies) + (.005 ${\times}$ number of guards), and (3) Small Area(3) = -5.381 + (.012 ${\times}$ number of security companies) + (.002 ${\times}$ number of guards). Second, we can classify national 16 areas into 3 clusters, such as Large Area(1), Medium Area(2), and Small Area(3) according to the sector of private security. The discriminant function D for each cluster is as follows: (1) Large Area(1) = -2224.402 + (-.562 ${\times}$ facilities security) + (1.245 ${\times}$ protection security) + (171.142 ${\times}$ convoy security) + (-2.722 ${\times}$ electronic security) + (2.020 ${\times}$ special security), (2) Medium Area(2) = -4.762 + (.052 ${\times}$ facilities security) + (.063 ${\times}$ protection security) + (-3.819 ${\times}$ convoy security) + (.110 ${\times}$ electronic security) + (-.165 ${\times}$ special security), and (3) Small Area(3) = -125.742 + (-.009 ${\times}$ facilities security) + (.432 ${\times}$ protection security) + (5.748 ${\times}$ convoy security) + (5.530 ${\times}$ electronic security) + (-.901 ${\times}$ special security).

OCR(Optical Character Recognition)의 오류를 줄이기 위해 본 논문에서는 교정 어휘 쌍의 혼동 행렬(confusion matrix)과 나이브 베이즈 분류기($na{\ddot{i}}ve$ Bayes classifier)를 이용한 철자 교정 시스템을 제안한다. 본 시스템에서는 철자 오류 중 한글에 대한 철자 오류만을 교정하였다. 실험에 사용된 말뭉치는 한국어 원시 말뭉치와 OCR 출력 말뭉치, OCR 정답 말뭉치이다. 한국어 원시 말뭉치로부터 자소 단위의 언어모델(language model)과 교정 후보 검색을 위한 접두사 말뭉치를 구축했고, OCR 출력 말뭉치와 OCR 정답 말뭉치로부터 교정 어휘 쌍을 추출하고, 자소 단위로 분해하여 혼동 행렬을 만들고, 이를 이용하여 오류 모델(error model)을 구축했다. 접두사 말뭉치를 이용해서 교정 후보를 찾고 나이브 베이즈 분류기를 통해 확률이 높은 교정 후보 n개를 제시하였다. 후보 n개 내에 정답 어절이 있다면 교정을 성공하였다고 판단했고, 그 결과 약 97.73%의 인식률을 가지는 OCR에서, 3개의 교정 후보를 제시하였을 때, 약 0.28% 향상된 98.01%의 인식률을 보였다. 이는 한글에 대한 오류를 교정했을 때이며, 향후 특수 문자와 숫자 등을 복합적으로 처리하여 교정을 시도한다면 더 나은 결과를 보여줄 것이라 기대한다.

계절변동조정방법인 X-12-ARIMA방법을 이용할 때에는 우리 실정에 적합한 옵션을 선택하고, 우리만에 특수한 명절과 조업일수영향을 사전에 조정해야한다. 본고에서는 명절과 조업일수영향을 측정하는 모형을 설정하고, 이것으로 추정된 사전조정요인을 원계열에서 제거했을 때 계절변동 및 계절변동조정계열의 안정성이 향상되었는가를 진단하고, 분류별로 적합한 X-12-ARIMA방법의 옵션을 제안하였다.
