Korea has enacted the Performance Evaluation law on the R&D Programs since 2006. This study categorizes program size, program history, sustainability, self-evaluation result as antecedents, and analyze the relationship between the antecedents and Meta-evaluation result, the change rate of appropriations. The result shows that program size, program history, self-evaluation result have significant effect to the Meta-evaluation result. And Meta-evaluation result has significant effect to the change rate of appropriations. This study has implication that the performance evaluation system shows significant effect to the appropriations.

This study introduces a threat level assessment model adapting Fuzzy theories in order to help make decisions for better covering quantitative factors and qualitative ones together. The threat is classified into three major categories - one resulting from navigational condition, another from target vessel specification and the other from external decision environment. The threat levels by each category are examined by a fuzzy inference, and its corresponding weights are assigned via fuzzy measures. Finally the high level threat measures become integrated via a Choquet Fuzzy Integral method into ultimate threat level indicators.

As Korean national R&D projects have steadily grown in size, the needs of enhancing the efficiency and effectiveness of the national R&D budge spending has been also discussed. Therefore, many efforts have been made to establish performance assessment system to improve the efficiency and effectiveness of the national R&D project. One example of such efforts is the stipulation of connecting the results of performance evaluation ranking of the national R&D projects with the budge allocation of for the coming fiscal year. Unlike the stipulated article in the law/regulation that 'more budge shall be allocated to a project rated over excellent grade and vice versa', however, precedent studies have been casting mixed opinions over to the effectiveness of the connection between assessment results and budge allocation. In this respect, the present study attempted to empirically examine if the laws and institutions related to the results of performance evaluation ranking of the national R&D projects with the budge allocation work properly, using panel regression analysis and quantitative data. In addition, this study investigated into the deterrent factors to the connectivity between the performance results of the national R&D projects and budge allocation and sought for a way to improve the system of performance assessment and enhance the reliability of the results by minimizing the hindrance factors.

The purpose of this paper is to assess the financial strength of general insurers by using A.M. Best's rating technique focusing on quantitative standards. A quantitative evaluation of fifteen larger general insurers' financial strength and operating performance relative to the Best's top group is carried out. The quantitative evaluation is done in 5 key areas; growth, efficiency, profitability, safety and liquidity. The results show that there is a big gap between domestic large insurers and American insures in all areas except stable growth of operations. Therefore, domestic insurers have to strive to strengthen financial soundness through profitability and should increase the capacity to retain more commercial business and reinsurance in order to become global players.

배터리를 주 전력원으로 사용하는 MANET(Mobile Ad hoc NETwork)에서 전력 소비를 줄이는 방법에 대한 연구가 활발히 진행되고 있지만, 이의 실험을 지원하는 시뮬레이션 도구를 찾아보기는 어렵다. 본 논문에서는 IEEE 802.11의 DCF-PSM 시뮬레이션 환경을 제공하기 위해 ns-2에 PSM 모듈을 구현하였고, 특히 전력 소비와 관련된 결과 자료를 쉴게 생성하기 위해 여러 가지 편의성을 제공하는 에너지 모델을 제안하였다. 이러한 모들의 개발로 PSM 환경에서의 상위 계층 프로토콜의 성능 평가나 PSM에 적합한 새로운 상위 계층 프로토콜의 개발이 가능해졌고, PSM을 개선하는 알고리즘의 구현과 그의 성능 평가도 훨씬 쉽게 이루어질 수 있게 되었다.

Collaborative filtering is a technique that effectively recommends unrated items for users. Collaborative filtering is based on the similarity of the items evaluated by users. The existing top-N recommendation methods are based on pair-wise and list-wise preference models. However, these methods do not effectively represent the relative preference of items that are evaluated by users, and can not reflect the importance of each item. In this paper, we propose a new method to represent user's latent preference by combining an existing preference model and the notion of inverse user frequency. The proposed method improves the accuracy of existing methods by up to two times.

In this paper, we investigated the affective components of facial beauty. In study 1, we did factor analysis of affective evaluations of the faces, and about 65% of the variances are explained by only two factors. Two factors were named 'sharp' and 'soft', respectively. In study 2, the correlation between facial beauty and affective evaluations was analyzed, and the correlation between facial beauty and sharp factor was significant. In study 3, we made the new images by morphing and warping the faces: 'average', 'high-ranked', and 'exaggerated'. The participants evaluated the 'high-ranked' face more beautiful than the 'average' face, and the 'exaggerated' face more beautiful than the 'high-ranked' face. The rating of affective words on the faces showed that the 'average' face was related to 'soft' impression, the 'high-ranked' image to 'sharp' impression, and the 'exaggerated' face might have double impression. These results might support the directional hypothesis for the facial beauty.

본 연구는 우리나라 대학의 창업교육센터(Entrepreneurship Education Center)에 대한 조사를 수행하여 선행 조사DB와 비교 분석하였다. 창업교육센터 실태조사를 바탕으로 대학별 정량적 정성적 지표를 측정하여 상위그룹과 하위그룹의 구분하고 두 집단의 차이점과 성공운영 요인을 분석하였다. 창업교육센터의 일반 현황과 특성, 교직원(교수자수, 교원창업자수), 교과목(과목, 수강인 원수), 학내외 프로그램(창업동아리, 창업경진대회, 창업캠프), 재정운영(예산, 전담인력) 등의 계량 지표는 대학정보공시(대학 알리미)와 중앙일보 대학평가 DB를 기초하여 조사하였다. 그리고 운영상의 문제점, 센터의 성과측정 항목 등 정성지표는 창업교육센터장을 대상으로 설문 조사하였다. 또한, 국내 창업교육센터의 표본특성을 살펴본 후 상위그룹과 하위그룹의 차이를 규명하여 상위그룹이 보유하고 있는 인적 물적 역량과 프로그램의 분석하여 창업교육센터의 활성화 방안을 제시하였다. 본 연구는 교육부의 "산학협력 선도대학(LINC) 육성사업 (2012년~2106년)"에서 창업교육을 총괄 지원하기 위해 2012년 대학에 설치된 전담조직인 61개 창업교육센터의 성과를 분석하고 대학평가에서 상위 순위에 있는 대학 그룹들의 차이점을 도출하는데 의미가 있다. 또한 2017년에 새롭게 지정된 LINC+ 사업 ('17년~) 창업교육 분야의 정책적 시사점을 제시한다. 본 연구의 목적을 달성하기 위해 문헌연구와 창업교육센터 운영에 대한 구조적 설문지를 개발하여 실태를 분석하였다. 이 결과는 창업교육센터의 효율적 운영을 위해 대학교직원 연구자 공무원 학생 및 창업교육센터를 포함한 창업지원 기관의 이해 관계자에게 향후의 발전을 위한 자료로써 의미가 있을 것이다.

The purpose of this study is to analyze Korean students' mathematics achievement characteristics and draw implications for better math education in schools through comparing the results of three east Asian top level countries, Korea, Singapore, and Japan in PISA 2012 results. As a results, the rate of correct answers of Korea students was relatively low compared with those of Singapore, but relatively higher than Japan. From the results of effect size, similar results from t-test was discovered. As shown in analysis according to sub-elements in math assessment framework, the Korean students had low effect size in every sub-elements than Singapore. and they had high effect size at most of sub-elements than Japan, except "personal" context. In top performing level(above level 5), the Korean students had high effect size at "quantities" in mathematical contents, and "employ" in mathematical processes compared with Singapore. And they had row effect size at 6 sub-elements compared with Japan.
