진보된 수리적 통계이론의 발전과 이의 실용을 위한 통계적 처리방법의 개발이 신속히 이루어지고 있는 것이 현대통계학의 추세이다. 이에 부합되는 통계학 교육을 위하여는 우리의 통계학 교육의 현황을 분석하여 이를 토대로 체계적인 교육을 추구하여야 할 것이다. 국내대학에 통계학과가 설립된 이래 교수의 부족, 통계학에 대한 인식의 부족 등에도 불구하고 통계학 교육은 꾸준한 발전을 계속하고 있다고 할 수 있다. 그러나 대다수의 통계학과가 설립된지 오래지 않아 교육과정에 대한 검토와 연구가 부족했던 것이 사실이다. 한편, 국내 통계학과들은 경상계 대학과 자연계 대학에 소속된 학과들로 대별될 수 있다. 이러한 점과 함께 교수의 부족, 교육시설의 빈곤으로 인하여 전체적으로 교육과정의 공통성이 결여되어 있으며 실용적인 면의 교육에 소홀한 경향이 있다. 따라서 통계학 교육의 체계적인 확립과 발전을 위하여 교육과정의 모형이 절실히 요구된다고 할 수 있다. 본 보고서에서는 (1) 대학원 통계학 교육의 예비단계로서의 학부교육과 (2) 사회에서 요구하는 통계전문가의 양성을 위한 교육으로 구분하여 각 경우에 적합한 교육과정의 모형을 제안함으로써 각 대학에서의 교육과정 편성에 도움을 주고자 한다.

효과적이고 체계적인 소프트웨어의 재사용을 위해서는 해당 도메인에 대한 공통된 자산을 먼저 개발해야 한다. 재사용을 위한 컴포넌트 집합은 복잡한 소프트웨어를 컴포넌트 단위의 구조로 분해하고 이를 다시 조립할 수 있도록 하여 생산성을 향상시키지만 광범위한 분석으로 인해 컴포넌트를 개발하는데 필요한 비용과 기간을 증가시키기도 한다. 이러한 문제점을 극복하기 위해 소프트웨어 제품 라인 공학을 적용하여 해당 도메인의 수요나 업무 수행을 만족하는 일련의 공통된 기능들을 이용하여 재사용할 단위인 핵심 자산을 구축하고 요구사항에 따라 목표 시스템을 단기간에 저비용으로 개발할 수 있다. 본 논문에서는 소프트웨어 제품 라인 공학을 통해 정의된 M&S프레임워크의 핵심 자산을 제시하고 이를 재사용해 기록장치 소프트웨어를 개발한 사례에 대하여 설명한다.

CC (Common Criteria) requires collecting vulnerability information and analyzing them by using penetration testing for evaluating IT security products. Under the time limited circumstance, developers cannot help but apply vulnerability analysis at random to the products. Without the systematic vulnerability analysis, it is inevitable to get the diverse vulnerability analysis results depending on competence in vulnerability analysis of developers. It causes that the security quality of the products are different despite of the same level of security assurance. It is even worse for the other IT products that are not obliged to get the CC evaluation to be applied the vulnerability analysis. This study describes not only how to apply vulnerability taxonomy to IT security vulnerability but also how to manage security quality of IT security products practically.

The NCO effectiveness analysis related elements and their relationship are more complicated than the PCW. However, Effectiveness analysis models provide single effectiveness element centric effective analysis method so far. Therefore, A model to provide unified view and common language about NCO effectiveness is required. EA use reference model as a common language to control complexity and change. The objective of this study is presenting a methodology to develop NCO effectiveness analysis model based on reference model and implementation model concept. To do this, First, the concept of EA based reference and implementation model is studied, Second, we study related effectiveness analysis method and model component and their relationship identification methodology, third, we propose methodology to develop NCO effectiveness analysis model. Finally, we prove the effectiveness of the methodology using case study.

현재까지 많은 기업들이 정보화를 대세로 인정하고 IT 투자에 막대한 기업 자원을 투입하였다. 특히 닷컴 버블까지 발생했던 지난 몇 년 간 대다수 기업들은 경쟁에서 뒤처지지 않기 위해서 정보화 투자에 대한 효익을 간과한 채 투자에 힘써온 것이 사실이다. 미국의 조사 기관 중 하나인 메타 그룹이 발표한 자료에 따르면 2001년 한 해 동안 전 세계의 대다수 기업들이 IT 투자에 쏟은 투자액만 총 2조 2000억 달러에 달하지만 ROI 등을 고려하여 투자한 기업은 드물었다고 한다. 그러나 세계적인 경기 침체에 따라서 기업 가치에 특별한 효익을 가져다주지 못하다고 판단한 기업들은 IT 투자를 축소하고 있거나 투자 효익에 대한 검증을 원하고 있다. 따라서 본 연구에서는 이러한 평가 방법론 중 대표적인 방법론으로 성과 중심의 BSC(Balanced Scorecard) 방법론, 프로세스 관점에서의 CMM(Capability Maturity Model) 방법론, 운영 관점의 6 시그마 방법론에 대해서 서로 비교 분석해보고 특히 6 시그마 방법론이 두 방법론들 사이에서 제시해 줄 수 있는 공통 관계 및 인과 관계를 분석함으로써 성과 관리 및 프로세스 관리에 대한 관점을 제시하고자 한다.

This study is to investigate the level and connection of learning concepts related to metabolism presented in life science textbooks developed according to the national common basic curriculum. One kind of elementary school, and three kinds of middle school and high school science textbooks were analysed. The gross number of concepts related to metabolism was 42 in elementary, 149 in middle and 126 in high school science textbooks. The number of concepts was much more different by school than by publisher. Ratio of the number of concrete versus formal concepts decreased gradationally by grade, but the number of learning concepts increased radically by grade. Thus, it is implied that science learning concepts are presented considering the number of concepts as well as cognitive level of learner, and unit and content are constructed on the connection among them in developing science curriculum and textbooks.

The purpose of this study is to provide basic data onto preparing soft landing plan of future education policy by exploring direction of future education for the common good using big data and keyword network analysis. Based on the big data provided by Textom, data was collected under the keyword 'future education + common Good' and then keyword network analysis was performed. As a result of the research, it was found that 'common good', 'social', 'KAIST future warning', 'measures', 'research', 'future education', 'politics' were common keywords in the social awareness of future education for the common good. The results of this study suggest that the social awareness of future education for the common good is related to factors related to human, physical environment, social response, academic interest, education policy, education plan, and related variables, It was closely related. Based on these results, we suggested implications for the support for the preparation of a soft landing plan of future education for the common good.

The data were collected from 171 physiologic malodor patients diagnosed in KUMC halitosis control clinic between 2008 and 2016. We selected 11 independent variables and 3 dependent variables, then planned to extract some convergent common factors affecting their physiologic malodor. We thought that those extracted convergent common factors could be utilized when preparing the contents of oral malodor preventive program. We used multiple regression analysis and path analysis method, for the analysis of influence of 11 independent factors to three salivary dependent factors(resting salivary flow rate, salivary buffering capacity, salivary precipitation rate). We have presented the physiologic malodor patients' chracteristics by descriptive statistical analysis, and also statistically analysed convergent common factors influencing directly or indirectly to their three dependent factors. We could reason that the sex, the character, the intake habit of breakfast, and the regular food intake habit could affect resting salivary flow rate, salivary buffering capacity and salivary precipitation rate.

Soil risk assessment models were used to determine the goals of soil remediation and to establish the soil quality standards in developed countries. Recently, Korean Ministry of Environment prepared the guideline for soil risk assessment. Soil risk assessment model applicable to Korean situation will be needed in the near future. In this study, three models for soil risk assessment were extensively compared to suggest the fundamental components that required for the soil risk assessment in Korea. The models considered in this study were CalTOX in the United States, CLEA (Contaminated Land Exposure Assessment) in the United Kingdom, and CSOIL in the Netherlands. The major exposure routes and the intake estimation equations suitable for Korean situation were suggested. The exposure routes suggested were intake of the crops, underground water, indoor outdoor soil ingestion, dust inhalation and a volatile matter inhalation. The equations for intake estimation used in CalTOX and CSOIL seem to be applicable for the calculation of the human intake in Korea.

This study is to clarify the effect of security majoring students' loyalty on department to future direction and job choice to suggest basic data for supporting student to prepare more active school life and future. The research object is security majoring male/female students among Y university in Gyeonggi-do Y city, K university in Gyeongsangbuk-do G city, k university in Gyeonggi-do S city between 1 Fab 2012 to 20 Aug 2012 and we randomly extracted the sample. In this research, we performed exploratory factor analysis and used principal components analysis and selected varimax direct rotation method to prove the reasonability of the contents. We then use the Cronbach's ${\alpha}$ value to measure the trust coefficient and during the process, the repeated or questions lack of correlation were deleted with judgment of researcher to improve trusty and reasonability.
