This study investigated the differences in time use patterns and psychological states across daily activity contexts and interpersonal contexts, depending on the levels of school maladjustment among elementary school students. Using the Experience Sampling Method (ESM), 107 elementary school 6th grade students' daily time use patterns and psychological states across daily contexts were measured six times a day over a period of 4 days. Using the school maladjustment scale, an internal problem based school maladjusted group and an external problem based school maladjusted group were identified and selected. The daily time use patterns and psychological states of both school maladjusted groups were compared to those of the adjusted groups. The principle findings are as follows: first, the school maladjusted group students' daily time use patterns across daily activity contexts or interpersonal contexts did not differ from those of the students from the school adjusted group. Second, the school maladjusted group students experienced more negative emotions, lower concentration levels, and lower motivation levels across daily contexts than the school adjusted group students. These differences in motivation between the external problem school maladjusted group and adjusted group, however, were greater in the schoolwork context compared to the other daily activity contexts. The findings were discussed in the contexts of the daily experiences of child school maladjustment.

The purpose of this study was to identify 1) the effect of two contexts (job interview, Informal outing) and clothing cues (type, style, color) on male impresssions 2) the effect of perceiver's age on male impressions created by the clothing cues and contexts. The subjects consisted of 256 male undergraduate students and 256 middle-aged men. The experimental materials developed for this study were a set of stimuli and response scales. The stimuli were 8 color photographs of drawings of a male figure in clothing which were manipulated in two levels, each of three clothing cues including type, style and color. The experimental design was full factorial design of $(2^4contex^2{\times}clothing type^2{times}clthing color^2$. Each of the 16 sub-samples includes 16 subjects from the two perceiver group. Questionnaires used to measure perceivers responses to the stimuli were 7-point semantic differential scales composed of 37 bipolar adjectives representing personal traits. The data was processed by factor analysis, ANOVA, multiple classification analysis, Duncan's multiple range test. The major findings drawn from this study were as follows: 1. Three factors emerged to account for the dimensional structure of the impressions of the male figure in clothing in two social situations. These factors involved evaluation, activity and uniqueness. 2. The contexts, clothing types and clothing styles had significant effects on evaluation, activity and uniqueness. The clothing styles had a considerable effect on both evaluation and uniqueness while the clothing types affected activity. The clothing color had least effect on the impression and had only moderate effect on evaluation. 3. Perceiver's age influenced impressions formed by the social contexts and clothing cues. Male college students were least affected by contexts and clothing cues, while middle-aged men wert affected most.

실제 환경에서 사람의 일상적인 활동을 학습하는 기술은 스마트 비서나 자율지능 로봇과 같은 인지 지능 시스템 개발을 위해 필요한 핵심 기술이다. 일상을 예측하는 대다수의 연구들은 센서 데이터의 패턴과 일상 활동 사이의 직접적인 상관관계를 탐색하는 것에 집중하였다. 하지만 일상에서의 인간 활동은 하나의 레이블로 표현하기 어려운 다수의 사건 집합이고 또한 서술 가능한 특성을 지니고 있다. 본고에서는 일상을 구성하는 사건 요소들을 우선 인식하고, 이후 일상 활동을 학습 및 예측하는 방법을 제안한다. 제안하는 방법은 개인의 일상에서 웨어러블 장치와 스마트폰으로부터 수집된 일인칭 시점의 멀티 센서 데이터로부터 위치 좌표, 장면 영상, 그리고 신체적 움직임에 기인한 사건 요소들을 각각 인식한 뒤, 이 정보들이 특정 활동 내역에 따라 조합되는 규칙을 학습하여 최종적으로 사용자의 일상 활동을 예측한다. 두 명의 실험 참가자가 각각 2주간 수집한 센서 데이터를 이용하여 실험한 결과는 제안한 방법이 센서 데이터로부터 추출된 특징을 일차적으로 사용하여 분류하는 기존의 방법과 비교하여 향상된 성능을 보였다.

The purpose of this study is to consider 1990s fashion design involving the utility of function which is the essence of modernism. First, documentary studies about the aesthetic value of the utility of function throughout the 20th century sociocultural contexts has been done. Second, content analysis of articles in American "Vogue" from 1990 to 2002 has been accomplished to hold the actual proof for the utility of function in postmodernism fashion. As a result, the utility of function has been defined the utility of body activity, the utility of practical use, and the utility of mechanical product. According to contents analysis, new aspects has been introduced in use of high-tech fabrics, ornaments, and mass customization in 1990s. In conclusion, the utility of function in fashion has been improved in accordance with the change of sociocultural contexts and women's wants.

학생의 선개념은 일상적 상황의 경험을 바탕으로 형성된 반면, 과학적 개념은 이상화된 상황을 전제로 하여 형성된 것이므로, 개념변화에 필요한 학생의 인지갈등을 유발하려면 이러한 상황의 불일치를 고려할 펼요가 있다. 또한, 학생들은 자신의 생각과 불일치한 현상을 대면하였을 때, 적당한 보조가설을 도입하여 이를 설명하려 함으로 개념변화가 이루어지지 않을 수 있다. 오히려, 과학적 개념이 일상적 상황에서 잘 맞지 않는다고 학생들이 생각할 수 있으므로, 과학적 개념에 따른 보조 가설을 도입하여 일상적 상황의 현상을 설명할 필요가 있다. 본 연구에서는 이러한 점들을 고려한 개념변화 모형을 구안하고, 이에 따라서 보조 가설의 대비를 통한 인지갈등의 명료화, 이상적 상황의 관찰을 통한 과학적 개념의 개념적 지위 상승, 교량적 실험활동을 통한 학생의 선개념의 지위 하강을 통하여 개념변화가 이루어지게 하는 세 단계로 구성된 학습지도 모형인 '구조화된 대비활동'을 제안하였다.

A commitment to physical activity is necessary for personal health, and is a primary goal of physical activity practitioners. Effective practitioners rely on theory and research as a guide to best practices. Thus, sound theory, which is both practical and parsimonious, is a key to effective practice. The purpose of this paper is to review the literature in search of such a theory - one that applies to and explains commitment to physical activity in the form of sport and exercise for youths and adults. The Sport Commitment Model has been commonly used to study commitment to sport and has more recently been applied to the exercise context. In this paper, research using the Sport Commitment Model is reviewed relative to its utility in both the sport and exercise contexts. Through this process, the relevance of the Investment Model for study of physical activity commitment emerged, and a more parsimonious framework for studying of commitment to physical activity is suggested. Lastly, links between the models of commitment and individuals' participation motives in physical activity are suggested and practical implications forwarded.

This paper proposed the context awareness reasoning system to provide the personalized services dynamically in a ubiquitous mobile environments. The proposed system is designed to provide the personalized services to mobile users and consists of the context aggregator and the knowledge manager. The context aggregator can collect information from networks through Open API Gateway as well as sensors in a various ubiquitous environment. And it can also extract the place types through the geocoding and the social address domain ontology. The knowledge manager is the core component to provide the personalized services, and consists of activity reasoner, user pattern learner and service recommender to provide the services predict by extracting the optimized service from user situations. Activity reasoner uses the ontology reasoning and user pattern learner learns with previous service usage history and contexts. And to design service recommender easy to flexibly apply in dynamic environments, service recommender recommends service in the only use of current accessible contexts. Finally, we evaluate the learner and recommender of proposed system by simulation.

모바일 환경이 보편화됨에 따라 사용자의 상황을 인식하고 관련된 각종 컨텍스트를 공유하는 기술에 대한 관심이 높아지고 있다. 컨텍스트 공유는 사용자의 의사소통을 보다 풍부하게 할 뿐만 아니라 사회적 관계를 원만하게 유지하도록 도와준다. 최근 각종 메신저나 모바일 어플리케이션에는 간단한 수준의 사용자 컨텍스트 공유가 적용되고 있으나 사용자 환경이 복잡해짐에 따라 더욱 다양한 컨텍스트의 인식과 공유가 요구된다. 본 논문에서는 다양한 센서 정보를 수집하여 사용자의 대표적 컨텍스트인 감정, 스트레스, 행동을 동적 확률 모델을 이용하여 인식하고 메신저에 연동하여 컨텍스트 정보를 공유하는 상황인지 메신저를 개발한다. 다양한 컨텍스트를 인식하기 위한 다중모델을 효과적으로 구성하고 아이콘 방식으로 컨텍스트를 표시한다. 개발한 시스템을 사용자 시나리오를 바탕으로 평가하여 유용성을 검증하였다.

This study analyzes the epistemological meaning of‘social construction’in mathematical instruction. The perspective that consider the cognition of mathematical concept as a social construction is explained by a cyclic scheme of an academic context and a school context. Both of the contexts require a public procedure, social conversation. However, there is a considerable difference that in the academic context it is Lakatos' ‘logic of mathematical discovery’In the school context, it is Vygotsky's‘instructional and learning interaction’. In the situation of mathematics education, the‘society’which has an influence on learner's cognition does not only mean‘collective members’, but‘form of life’which is constituted by the activity with purposes, language, discourse, etc. Teachers have to play a central role that guide and coordinate the educational process involving interactions with learners in this context. We can get useful suggestions to mathematics education through this consideration of the social contexts and levels to form didactical situations of mathematics.
