The purpose of this study was to make an analysis of the conceptual diagrams of early childhood teachers about education for happiness in an effort to suggest the possibility and guidelines of this education. The subjects in this study were 100 teachers at kindergartens and daycare centers located in the city of Busan and South Gyeongsang Province. Out of them, 50 teachers each were selected from the kindergartens and the daycare centers. The conceptual diagrams drawn up by the early childhood teachers were analyzed to find out the numbers of superordinate concept, the number of content element, characteristics, hierarchy and density. The findings of the study were as follows: First, as for the content of education for happiness, superordinate concepts appeared 364 times in the conceptual diagrams of the kindergarten teachers, and there were 21 superordinate concepts overall in their diagrams. Second, concerning the content of education for happiness, superordinate concepts appeared 296 times in the conceptual diagrams of the daycare center teachers, and there were 18 superordinate concepts in total. The findings of the study showed that the kindergarten teachers had a better knowledge on the concept of education for happiness than the daycare center teachers, and that there was a difference between the two groups in what they considered valuable in relation to the content of education for happiness.

In previous study, visual representation competence taxonomy (VRC-T), which is composed of two dimensions, was developed for the purpose of promoting effective visual representation use and research in science education. In this study, elementary school students' visual representation competence for shadow phenomenon was investigated using VRC-T. In terms of visual representation competence, 'interpretation' was the highest score, followed by 'construction' and 'integration'. It also showed that students' visual representation competence was not high even after learning shadow-related units in the regular curriculum. On the other hand, text-based scientific knowledge was not correlated with all categories of visual representation competence. This indicates that there is a need to emphasize visual representation more in science class. Finally, hierarchical relationship among cognitive processes of VRC-T was explored according to ordering theory. If the tolerance level is somewhat loosened, a linear hierarchical relationship was found between the six cognitive processes. This suggests that VRC-T is an analytical framework that can be useful when designing assessment tools, tasks, and science class activities to enhance visual representation competence.

본 연구에서는 침출수를 비롯한 매립지의 각종 오염물질 배출로 수자원이 오염되어 피폭체의 피해가 빈발하는 문제를 해결하기 위해서, 매립지의 상대적 유해성을 평가하여 한정된 환경관리 예산의 합리적 배분을 위한 우선순위를 결정할 수 있는 의사결정 지원도구로서 LHR(Landfill Site Hazard Ranking)모형을 개발했다. LHR모형은 다요소의사결정(多要素意思決) 기법에 정성적 위해성(危害性) 평가기법을 접맥시켜 주관적 가중치를 모형에 반영한 가치내재화(價値內在化) 모형이다. LHR모형은 피폭체의 주요 피폭경로를 지하수 이동경로와 지표수 이동경로로 보았으며, 각 이동경로별로 누출 가능성, 폐기물 특성 및 피폭체 특성으로 요소범주를 3종류로 구분하여 폐기물의 독성이나 매립량같은 특성이 매립지의 수리지질학적 요소 및 자연지리적 요소에 의해 결정되는 오염물질의 누출 가능성을 통해 매립지 주변의 지역주민과 취약한 수생태계 같은 피폭체에 끼치는 매립지의 유해성을 상대적으로 평가했다. 그리고 LHR모형에서는 매립지 유해성을 공기 이동경로 및 사회경제적 측면에서도 평가하기 위해 매립지 이격거리별 토지이용 형태의 유해성을 평가했다. 그리고 각 평가요소별 가중치는 위계분석과정(位階分析過程)의 쌍대비교법(雙對比較法)에 의하여 할당했으며, 민감도 분석으로 LHR모형을 검증했다.

McCarthy(1960) 이후 오랫동안 4P 스키마타에 대한 논의가 없다시피하다가 Waterschoot and Van den Bulte(1992)가 특히 촉진믹스에 문제가 많음을 지적함으로써 마케팅믹스 분류체계에 대한 논의가 다시 시작되었다. 하지만 이들 논의 내용 또한 '4P 스키마타'를 재해석하는 정도이지 이를 넘어서지는 못하고 있다. 필자들은 4P 스키마타의 한계점을 Hunt(1983, 1991)의 스키마타 평가기준에 따라 크게 네 가지로 지적한다. 먼저 분류대상의 속성이나 특징이 명확하지 않고, 다음으로 실무의 흐름을 제대로 반영하지 못하여 유용성에 문제가 있으며, 세 번째로 분류된 범주간에 배타성과 포괄성이 부족하다. 끝으로 4P 간에 순서나 위계가 없어 문제의 진단이나 투자의 효율성을 논의하기가 어렵다. 이런 점들을 고려하여 연구자들은 4P를 원점활동과 접점활동으로 나누고 Parasuraman, Zeithaml, and Berry(1985; 1988 a,b; 1994)의 갭 모델을 원용하여 마케팅믹스의 새로운 분류체계인 '갭 스키마타'를 제안한다. 접 스키마타는 고객 갭과 마케터 갭 1, 2, 3, 4로 구성된다. 고객 갭이란 고객의 기대와 지각간의 차이 즉, 고객만족을 뜻하고 갭 1이란 마케팅조사를, 갭 2, 3은 원점활동을, 갭 4는 접점활동을 지칭하다. 원점활동인 갭 2란 상품기획, 브랜딩, 가격책정으로 구성되며; 갭 3은 광고 및 판촉으로 구성되고; 집 4는 유통 및 물류, 인적판매내지는 영업, 고객서비스로 구성된다.

The purpose of this study was to examine the effectiveness of utilizing a concept map as an instructional strategy to promote student achievement through semantical learning in elementary school on volcanoes. To analyze student achievement in understanding the concept of volcano, quantitative and qualitative analyses were performed through a written test for two different groups that were composed of 80 sixth-grade students: a control group that attended class using the conventional strategy and an experimental group that attended class using concept maps. The results of this study were as follows: First, the use of concept maps in class is effective in learning because of the higher understanding of the group that was using concept maps in the achievement assessment. Second, in their post-instructional understandings, no significant differences are shown between middle- and low-ranking students statistically, but a significant difference is shown between high- and low-ranking students or between high- and middle-ranking students. This indicates that the use of concepts maps in a class is more effective for the middle- and low-ranking students than for the high-ranking students. Third, in the repetitions of classes, the students learning with an aid of concept maps became accustomed to structuring the concepts of their learning subject in categories of relationships, hierarchies, cross-links, and examples easily.

Applying perceptual hierarchy of facial feature points, a neural network model for recognizing facial expressions was designed. Input data were convolution values of 150 facial expression pictures by Gabor-filters of 5 different sizes and 8 different orientations for each of 39 mesh points defined by MPEG-4 SNHC (Synthetic/Natural Hybrid Coding). A set of multiple regression analyses was performed with the rating value of the affective states for each facial expression and the Gabor-filtered values of 39 feature points. The results show that the pleasure-displeasure dimension of affective states is mainly related to the feature points around the mouth and the eyebrows, while a arousal-sleep dimension is closely related to the feature points around eyes. For the filter sizes. the affective states were found to be mostly related to the low spatial frequency. and for the filter orientations. the oblique orientations. An optimized neural network model was designed on the basis of these results by reducing original 1560(39x5x8) input elements to 400(25x2x8) The optimized model could predict human affective rating values. up to the correlation value of 0.886 for the pleasure-displeasure, and 0.631 for the arousal-sleep. Mapping the results of the optimized model to the six basic emotional categories (happy, sad, fear, angry, surprised, disgusted) fit 74% of human responses. Results of this study imply that, using human principles of recognizing facial expressions, a system for recognizing facial expressions can be optimized even with a a relatively little amount of information.

Child sexual crimes have increased, but there has been no effective plan to combat this. Films reporting problems, amplify the attentions and propose countermeasures, which leads to changes. The current study examined the audiences' reactions to child sexual crime faction films using text-mining. The analysis of Naver's 2,727 blogs showed realistic words while 3,000 review comments' analysis demonstrated emotional responses. The positive and negative emotional category and degree were also different. In , the higher degree of negative emotions, such as 'angry' and 'unpleasant' appeared frequently. In , only negative emotional worlds were used. On the other hand, 'sad' was the highest ranked word, and the negative level was weak. In , 'good' a positive emotional word solely emerged. The audiences perceived the accidents objectively before release while they expressed their emotions and feelings after watching the movies. caused explosive anger and organized the participating citizens for changes. This movie provided an opportunity to enforce a legislative bill intensifying heavy punishments. The present study is significant in scrutinizing the audiences' diverse emotional reactions and discusses the future direction of society prosecution movies. Based on the text analysis of the audiences' linguistic expressions, a future study will be needed to hierarchically classify the diverse emotional expressions.

This study distinguishes the aging population as young-old and old-old women. It examines the difference of each variable between young-old and old-old women. Also, it examines the effect of physical, psychological, social, economic and environmental factors on the quality of life for older adults in both groups and compares the effects on the quality of life between both groups. The sample of this study is collected from Daegu and Kyungbuk province and the sample size of this study is 310. As statistical method, t-test, $X^2$ and hierarchical multiple regressions are used. As demographic factors, age, marital status, income and education are controlled. The research results show that marriage, perceived health, self-esteem and social support are important factors of affecting on the quality of life for both groups. However, for young-old group, the perceived economic hardship and the receipt of social welfare affect negatively and social participation affects positively on the quality of life. On the other hand, for old-old group, informative social role affects positively and social participation affects on the quality of life negatively.

Concept mapping is a device for representing the conceptual structure of a subject discipline in a two dimensional form which is analogous to a road map. In the teaching and learning of earth science, each concept depends on its relationships to many others for meaning. Using concept mapping in teaching helps teachers and students to be more aware of the key concepts and relationships among them. The purpose of this study is to investigate the effect of the use of concept mapping on science achievement and the scientific attitude in ocean units of earth science. The results of this study are as follows; first, the science achievement of a group of concept mapping teaching is significantly higher than that of the group of traditional teaching. Also, when the achievement levels are compared among different cognitive ability groups, the effect is more significant in mid or lower level student groups than in high level groups. The use of concept mapping is more effective when the concepts have a distinct concept hierarchy. Second, the scores of the test of ‘attitude toward scientific inquiry’ and ‘application of scientific attitude’ of the group of concept mapping teaching are significantly higher than those of the group of traditional teaching, whereas the scores of the test of ‘interest in science learning’ of concept mapping teaching is not different from those of group of traditional teaching. Third, the survey on the use of concept mapping shows a positive response across the tested groups. The use of concept mapping is more beneficial in fostering the comprehension of the topic. A concept map of student's own construction facilitates the assessment of learning, thus promising the usefulness of concept mapping as a means of evaluation. In regard to retention aspect, concept mapping is considered to be more effective in confirming and remembering the topic, while less effective in the aspects of activity and interest. In conclusion, the use of concept maps makes learning an active meaningful process and improves student's academic achievement and scientific attitude. If the concept mapping is more effectively as an active teaching strategy, more meaningful learning will be attained.

Pedestrians not only walk along pedestrian pathways, but also choose unusual routes such as passing through buildings or crossing large scale open spaces. This study defines these unusual paths as social path, and includes them into one of the pedestrian road categories. Previous pedestrian accessibility and route choice studies could not evaluate correctly the space connectivity or optimal route because the social path was not considered properly. Therefore, this study analyzes the effectiveness of the social path in view of space connectivity focused on Coex and Seoul stations in Seoul, which are representative transit oriented development(TOD) areas. Global integration, which is widely used in network analysis, is selected (as performance index) to identify the space hierarchy and define new pedestrian links. The study results show that the network connectivity is improved especially in the main streets and social paths. This study demonstrated that the social path should be considered in finding the pedestrian optimal route from the practical perspective.
