The objective of the study is to identify the relationship among dominant design determinant factors, product core elements and digital TV. For that, this study uses structural equation modeling through a questionnaire. As a result, dominant design determinant factors effect on product core element such as display, design, characters while display and design influence on dominant digital TV. The study is expected for our TV firms to utilize our research as basic data to build their strategy so as to keep as first movers forever.

This study explores the health behaviors and related situations of Korean low-income breast cancer survivors using in-depth interview. The study derives 95 concepts, 23 sub-categories and 12 categories in open coding. Illness experiences were categorized by behavioral, psychological, and social domains, cognitive were categorized by causal and destiny thought, emotions were categorized by negative, positive emotion, reserve capacity were categorized by internal and external domains and health behaviors were categorized by behavioral, psychological, and social domains. Understanding illness experience, cognitive, emotion, reserve capacity and health behaviors for Korean low-income breast cancer survivors will be useful in developing social welfare interventions and for enhancing health promotion.

This study describes the semantic theoretic interpretation through the extensive use of semantic metaphors for intensive web interface with information and the metaphoric value of metaphors for interface design. Common factors that influence web design are empirical establishment and verification for generating web symbols and these are have important elemental perspectives that are used to assess the usefulness and key elements of the site. In addition, the structure of the screen has begun to change dynamically from the application of web technological functions, and the media functions have become important to make web standards when implementing visual structuring from the perspective of semiotic. Instead of using a technical expression approach to examine semiotic, a semiotic approach is applied to create aesthetic codes through the human-computer interface in terms of semiotic in a variety of natural and universal fields. Based on this, it is used as means of communication to convey the intended meaning to users so as to highlight the importance of the usability issues and metaphors user interface.

Catalogue raisonne is a holistic work record of artist which describes academically significant record information related to works by cataloging major works of an artist. Such catalogue raisonne is used as research material for exhibition planner and researchers and even used as fundamental material for winnowing out authenticity of work. Compilation of domestic catalogue raisonne is at an opening step, but in foreign countries, the art related institutions and artist foundations play key role in compiling catalogue raisonne of artists. Cataloge raisonne is an essential element of record about the art work and relevant information. However, as the description of catalogue raisonne can vary in accordance with characteristics of artist and art work. Therefore, this study has analyzed catalogue raisonnes of artists published in foreign countries, examined the characteristics and description element of catalogue raisonne in details and aims to contribute to compilation of catalogue raisonne of authoritative domestic artists.

'지속가능화학'에서는 사회 구성원이 심리적이고 주관적으로 느끼게 되는 '위험성 인식'(risk perception)이 주요하다. 위험 인식은 단순한 기술적 평가가 아니라 개인의 심리적 요소와 함께 자신이 화학물질의 영향을 어느 정도까지 통제할 수 있는가의 정도에 따라서 달라질 수 있다.

Relevance judgment is important in terms of improving the effectiveness of information retrieval systems, and it has been dominant for users to search and use images utilizing internet and digital technologies. However, in the field of image retrieval, there have been only a few studies in terms of identifying relevance criteria. The purpose of this study aims to identify and characterize the non-relevance criteria from the failed image searches. In order to achieve the purpose of this study, a total of 135 participants were recruited and a total of 1,452 criteria items were collected for this study. Analyses and identification on the data set found thirteen criteria such as 'topicality', 'visual content', 'accuracy', 'visual feature', 'completeness', 'appeal to user', 'focal point', 'bibliographic information', 'impression', 'posture', 'face feature', 'novelty', and 'time frame'. Among these criteria, 'visual content' and 'focal point' were introduced in this current study, while 'action' criterion identified in previous studies was not shown in this current study. When image needs and image uses are analyzed with these criteria, there are distinctive differences depending on different image needs and uses.

National and international regulations on the exhaust gases of diesel engines are being strengthened, and a study of the combutsion engine and the post-porcessing system are in progress as a variety of ways. There are many techniques for the removal of nitrogen oxide like HC-SCR, LNT, Urea-SCR. And the technical development on the Urea-SCR owing to high conversion efficiency and fuel economy characteristics has being processed. This study investigated the physical/chemical properties of urea according to the change of the urea content, and were analysed the characteristic of exhaust gas. According to the increase of urea content, the contests of biuret aldehyde, phosphate content was increased and the changes of emission quantity of carbon monoxide, hydrocarbons and particulate matter in the exhaust gas was very slight. The emission quantity of NOx was decreased in accordance with increasing the urea content and it was shown to be more than 80 % in the urea solution having more than 30 wt%.

This study aims to clarify the concept of 'Low-carbon urban regeneration', to extract planning elements according to it, and to establish the planning system. In order to extract the elements, matrix analysis was conducted between planning elements of urban regeneration and Low-carbon cities, and the focus group interview(FGI) was used. Derived elements from this process were restructured for the new planning system. In addition, in-depth case analysis was performed to verify the suitability and effects of planning elements and system. The result showed that planning element of Low-carbon urban regeneration can be sorted in 37 elements in 5 categories. In-depth analysis indicated that established planning elements were importantly dealt in cases and played a significant role in urban regeneration and carbon reduction. Also, it showed that those elements had a significant relationship with adaptation and mitigation, the two responding strategies to the climate change. Elements highly contributing to urban regeneration were Urban Structure, Transportation, Policy while elements affecting carbon reduction were Transportation, Green & Blue space, Energy & Material field.
