특정 제품이 가진 "감성 이미지"란 그 제품의기능과 함께 제품의 감각적 요소 그리고 사용자가 제품에 대해 가진 개념적인 사고 과정의 산물이다. 감성이미지의 국제 비교 연구는 사용자가 특정 제품에 대해 가지고 있는 이미지를 국가나 문화의 맥락 속에서 상호 비교 평가하여, 각 국가나 사회집단을 특팅지울 수 있는 문화적 감성 요소를 추출하고자 하는 것이다. 즉, 각 국가의 생활문화 속에서 사용자들이 제품에 대해 가지는 감성이미지를 계량적으로 규명하고 비교 평가하며, 이 정보를 기초로 각국의 문화와 정서에 적합한 제품 디자인의 모형을 제시하는데 본 연구의 목적이 있다. 구체적인 연구방법은 우선, 자동차 제품을 중심으로 '제품 이미지'를 나타내는 '언어 이미지'스케일을 각 문화 집단 별로 구성한다. 이 제품 이미지에 대비하여, 감성적 요소로 선정된 표준 색채 스케일을 중심으로 나타난 집단의 '이미지'를 상호 비교 평가한다. 이 경우, 각 국가별 집단에서 특징적으로 나타나는 제품의 주요 특성이 감성 이미지로 표현되는 색채 이미지에 어떻게 반영되는가를 상호 비교한다. 이 연구에서는 특정 지역의 사람들이 제품에 적용하는 감성이미지는 색채나 기타 감성 요소에 대한 선호의 문제가 아니라 그 집단의 사람들이 그 제품을 통해 표현하고자 하는 사회적 표상의 반영이라는 것을 보여준다. 따라서, 제품의 이미지가 각 국가별로 공유되는 감성 이미지로 변환되기 위해서는 동일한 의미나 상징성을 지닌 감성 요소를 활용하여 그 제품의 이미지를 포장할 수 있는 방법을 적용하는것이다. 본 연구에서는 각 문화 집단들이 특정 제품에 대해 가지고 있는 사회적 표상(social representation) 체계를 색채스케일에서 나타난 감성 이미지를 통해 구체화하는 것이다.로서는 방전효율의 저하가 없는 양호한 성능을 보였으며, SC의 시범 작동시험을 실차(소나타 1800cc)에 장착하여 수행한 결과 20회 이상의 연속시동에서도 아무런 문제점 없이 잘 동작하였다.되는 데이타를 입력한후 마우스로 원하는 작업의 메뉴를 선택하면 된다. 방법을 타액과 혈청내 testosterone 농도 측정에 응용하여 RIA의 결과와 비교하여 본 바 상관관계가 타액에서 r=0.969, 혈청에서 r=0.990으로 두 결과가 잘 일치하였다. 본 실험에서 측정된 한국인 여성의 타액내 testosterone농도는 107.7$\pm$12.0 pmol／l이었고, 남성의 타액내 농도는 274.2$\pm$22.1 pmol／l이었다. 이상의 결과로 보아 본 연구에서 정립된 EIA 방법은 RIA를 대신하여 소규모의 실험실에서도 활용할 수 있을 것으로 사려된다.또한 상실기 이후 배아에서 합성되며, 발생시기에 따라 그 영향이 다르고 팽창과 부화에 관여하는 것으로 사료된다. 더욱이, 조선의 ${\ulcorner}$구성교육${\lrcorner}$이 조선총독부의 관리하에서 실행되었다는 것을, 당시의 사범학교를 중심으로 한 교육조직을 기술한 문헌에 의해 규명시켰다.nd of letter design which represents -natural objects and was popular at the time of Yukjo Dynasty, and there are some documents of that period left both in Japan and Korea.

Special security guards working at nuclear power plants, one of the country's major facilities, serve as human protection to safeguard from threats to nuclear facilities and nuclear materials. The purpose of this study was to develop a physical fitness program for fitness management that is essential for the completion of missions of special guards. This program was designed to prepare the physical fitness test proposed by Jeong et al. (2019). Researchers conducted literature analysis, research meetings, expert meetings and pretests, and developed a 90-minute physical fitness program for 6 weeks, 3 times a week. In order to verify the effectiveness of the developed physical fitness program, the experiment was conducted on 29 subjects(control group: 15, exercise group:14). Specifically, a six-week physical fitness program was conducted for exercise groups, and the fitness test for a special security guard was conducted for all subjects before and after the experiment. As a result, it was found that the physical fitness program was effective in improving the performance of 20m shuttle run, leg tuck, 20m sprint & carry, and medicine ball back throw. Until recently, problems of neglecting fitness management of security guards have been pointed out. It is expected that the physical fitness program proposed by this study will be a practical alternative for security guards' fitness management.

Although fairly descent amount of research outcomes has been generated on problem-based learning(PBL) with regard to science and medical subjects, relatively less outcome has been generated on social science and management subjects. Therefore this study attempts to exam effect of problem-based learning in food service entrepreneurship subject on improving problem solving skills. After literature review, for constructing for this research frame, each class schedules were formed by hybrid-PEL and traditional lecture style respectively then problems, solution, and evaluation process were generated for hybrid-PBL. Through the result, there was hardly any differences occurred before and after traditional lecture approach on students' problem solving skills. There was, however, certain differences appeared on students' skills after hybrid-PBL approach. Through the study, hybrid-PBL learning can be an effective teaching method in social science and management subject for improving students' problem solving skill.

This paper presents a semantic vector space retrieval model incorporating a word sense disambiguation algorithm in an attempt to improve retrieval effectiveness. Nine Korean homonyms are selected for the sense disambiguation and retrieval experiments. The total of approximately 120,000 news articles comprise the raw test collection and 18 queries including homonyms as query words are used for the retrieval experiments. A Naive Bayes classifier and EM algorithm representing supervised and unsupervised learning algorithms respectively are used for the disambiguation process. The Naive Bayes classifier achieved $92\%$ disambiguation accuracy. while the clustering performance of the EM algorithm is $67\%$ on the average. The retrieval effectiveness of the semantic vector space model incorporating the Naive Bayes classifier showed $39.6\%$ precision achieving about $7.4\%$ improvement. However, the retrieval effectiveness of the EM algorithm-based semantic retrieval is $3\%$ lower than the baseline retrieval without disambiguation. It is worth noting that the performances of disambiguation and retrieval depend on the distribution patterns of homonyms to be disambiguated as well as the characteristics of queries.

This study aims to identify the most effective statistical feature selecting method and context window size for word sense disambiguation using supervised methods. In this study, features were selected by four different methods: information gain, document frequency, chi-square, and relevancy. The result of weight comparison showed that identifying the most appropriate features could improve word sense disambiguation performance. Information gain was the highest. SVM classifier was not affected by feature selection and showed better performance in a larger feature set and context size. Naive Bayes classifier was the best performance on 10 percent of feature set size. kNN classifier on under 10 percent of feature set size. When feature selection methods are applied to word sense disambiguation, combinations of a small set of features and larger context window size, or a large set of features and small context windows size can make best performance improvements.

This study analyzed the effects influencing the elderly's knowledge on fire safety and practices of fire safety accident prevention after developing a Fire Safety Education Program for the elderly. The program was developed through verification using some experts and a pilot study after selecting the objective, goals, contents, and teaching & learning methods of the program based on the basic survey and literature review. The effects of the program were verified by conducting some non-equivalent control group pre- and post-tests after dividing the targets into the experimental group (the Fire Safety Education Program for the elderly was implemented) and control group (only printed hand-outs were given) among 48 elderly people no younger than 65 years of age. A paired t-test revealed some statistically significant differences between the scores of the pre- and post-tests of the experimental and control groups. ANCOVA found that the effects of the program were significantly higher than those of the printed hand-outs because the post-test scores of the experimental group were higher than those of the control group.

웹사이트를 어떻게 디자인했을 때 지식을 보다 효율적으로 전달할 수 있는가에 많은 관심이 쏠리고 있다. 최근의 몇몇 커뮤니케이션 연구들은 인터넷의 독특한 정보 전달 구조인 하이퍼텍스트 구조가 정보 전달에 있어서 핵심적인 영향을 끼치고 있으며, 따라서 하이퍼텍스트를 어떤 방식으로 구조화하는지에 따라 지식의 전달 내용도 바뀔 수 있다고 주장하고 있다. 이 연구는 이러한 학자들의 의견과 궤를 같이 하여, 이용자의 사전 지식의 차이에 따라 비선형적 웹사이트 구조가 구조적인 지식과 선언적인 지식을 전달하는 데, 어떠한 차이점을 가지는지를 시험적으로 검증한 예비 조사적 연구이다. 관련된 기존 문헌 연구를 통해, 사전 지식이 높은 이용자는 선형 구조보다는 비선형 웹 구조를 통해서 구조적인 지식을 습득하는 데, 유리할 것이고 사전 지식이 낮은 이용자는 선형 구조보다는 비선형 웹구조를 통해서 학습할 때, 선언적인 지식을 습득할 확률이 높을 것이라고 예상되었다. 이를 소규모 집단 실험으로 검증한 결과, 통계적으로 유의한 수준은 아니었지만 비선형적 웹구조는 구조적인 지식을 증가시키는 경향성이 발견되었다. 또한 사전 지식이 높은 이용자 역시 비선형 구조에서 높은 구조적 지식을 습득하는 경향성이 있었다. 그러나 선언적인 지식의 경우에는 웹 구조의 영향이 크게 상관이 없는 것으로 나타났다.

In this paper, classification feature is selected with focus of musical content, note sequences pattern, and measures similarity between note sequences followed by constructing clusters by similar note sequences, which is easier for users to search by showing the similar note sequences with the search result in the CBMR system. Experimental document was $\ulcorner$A Dictionary of Musical Themes$\lrcorner$, the index of theme bar focused on classical music and obtained kern-type file. Humdrum Toolkit version 1.0 was used as note sequences treat tool. The hierarchical clustering method is by stages focused on four-type similarity matrices by whether the note sequences segmentation or not and where the starting point is. For the measurement of the result, WACS standard is used in the case of being manual classification and in the case of the note sequences starling from any point in the note sequences, there is used common feature pattern distribution in the cluster obtained from the clustering result. According to the result, clustering with segmented feature unconnected with the starting point Is higher with distinct difference compared with clustering with non-segmented feature.
