Closely connecting Well-Being culture with our traditional eating culture. we can predict next generation Kimchi refrigerator trend with this research. In the highly developing industrial society, design has been playing the central role in the managerial strategy of a company and has been one of the central agendas in determining the economical competence of a country, and has also been regarded as a means to acquire sustainable superior competence. Thus, these trends suggest that the aesthetic value of product has become more important than its technological function. In this study we reviewed theoretically esthetic factors influencing the preference and the evaluation of a product and made a list of eight esthetic factors based on various referential studies which include simplicity, balance, unity, rhythm, style, novelty, typicality, and proportion. Also on the point of view of design, it is necessary to find out definitely the consumer preference frame the relationship among design preference design image design attribute. Will give you guidelines on which designers can select and design some more objective and reliable design factors, finding out the relation of cause and effect by which they can know what kind of product designs their consumers like and how the popular image which that product offer is composed of. We investigated the esthetic factors affecting consumers preferences and the basis for evaluating a product. Aimed at providing materials for developing product design by presenting an ,esthetic guideline product design by presenting an esthetic guideline and to put these materials to practical use. Investigated other considered elements classified by manufactures and importance of esthetic factors and its influence on consumer tastes . All of these result, It could not conclude all of the adjective design image and design factors of every consumer, but through consumer reaction framework consumer are response and prefer the products which design image have. and then understand prefered design image are influenced to design factor's and could be apply to new design development.

Objectives : The purpose of this study was to evaluate community mental health professionals and hospital workers attitude and awareness towards suicide. Methods : This study investigated 264 community mental health professionals and 228 hospital workers. SOQs (Suicidal Opinion Questionnaires) were used from July 2007 to September 2007. After a factor analysis for the attitude towards suicide, the items on ethics, mental illness, religion, risk, and motivation were included in the subsequent analysis. Results : There were significant differences in the attitude towards suicide according to religion, age, educational background, the marriage status, the economic position, and different professional licenses. Hospital workers' view was different from the community workers'. The hospital workers judged that suicide was due to mental illness, and suicide was high for the people in a special environment and who lacked motivation, which caused them to fall in a dangerous situation. For the lower educational group, they thought that suicide was attributable to mental illness. The awareness for suicide was significantly higher in the group with a postgraduate education, unmarried people, mental health professionals and the persons who had concern and experience with suicide. The factors that had an influence on the awareness of suicide were the items of mental illness, religion, risk and motivational factors. Conclusions : This study suggested that the factors to increase the awareness and attitude for suicide were the experience of increased education and case management of suicide. Therefore, education dealing with suicide and reinforcement of crisis management programs should be developed.

The $St{\ddot{o}}ckigt$ sizing test of the most-commonly used sizing tests is easily influenced by the individual testers' bias in recognizing red coloration. Therefore the test had to be modified to improve its reliability and reproducibility by automated recognition of a coloration procedure during testing. In order to achieve this, all measured variables occurring during the $St{\ddot{o}}ckigt$ test was first be analyzed and then reflected in the new automatic system. Secondly, the most important principle applied was to transform the RGB values of the droplet image to hue (H), saturation (S) and value (V) respectively. This is because RGB cannot be used as a color standard, owing to RGB's peculiarity of being seriously affected by the observer's point of view. Therefore, the droplet color had to be separated into three distinct factors, namely the HSV values, in order to allow linear analysis of the droplet color. When the average values of the vectors calculated during color variation from yellow to brown were plotted against time, it was possible to determine the vector value of hue, the most sensitive factor among HSV, at the specific time by differentiation of a function when it exceeds the critical point. Then, the specific time consumed up to the critical point was regarded as the $St{\ddot{o}}ckigt$ sizing degree. The conventional method took more time to recognize an ending point of coloration than the automatic method, and in addition the error ranges of the conventional sizing degrees on the specific addition points of AKD were wider than those of the automatic method.

The spiral form, which comes from the organic form of natural phenomenon such as growth of creatures, has been used as a factor of formative shape in various fields of art until now. In conjunction herewith, this study intends to discover and express the life force and the formative beauty of natural substances with the organic spiral forms into clothing design, using various creating methods and materials such as Korean traditional paper. The natural substances with the spiral structure, such as seashells, land snails, passion flower, curled flower, growing chart of plants, Impatiens textori was used as subjects of the designs. The seven pieces of work were completed with attempts to develop aesthetic forms through the presentation techniques and methods via restructuring process of simplification, partial transformation and consolidation. Through such process the conclusion of this study is as follows: First, the nature, with unlimited possibilities, could be subject of human formative activities, leading to the creative world of formative art for designers. Second, adaptation of the spiral organic forms of nature into the contemporary clothing designs proved the motif as a source of inspiration of diverse subject, in recognition with its innate formative beauty as well as external shape. Third, design expressions via restructuring process of simplification, partial transformation and consolidation with designer's subjective point of view were adequate for the creations of contemporary fashion designs. Fourth, the Korean traditional paper, as a fine material for various shape according to the handling method, could be used appropriately in the contemporary clothing designs, expressing our aesthetic senses. Fifth and finally, expansion of the realm of formative expression of clothing through the development of possibilities of expression in contemporary clothing would enhance the creative possibilities of clothing design as formative art. In conclusion, the expression of clothing design as formative art was developed on the emphasis of re-creation of natural objects of the organic spiral form. For the future study, the applications of spiral form into everyday clothing designs, consolidating artistic senses and practical senses, are expected as opportunity of proposing developmental possibilities of the contemporary clothing designs.

The second-stage near surface disposal facility for low and very low level radioactive waste's permanent disposal is to be built. During the institutional control period, the inadvertent intrusion of the general public is limited. But after the institutional control period, the access to the general public is not restricted. Therefore human who has purpose of residence and resource exploration can intrude the disposal facility. In this case, radioactive effects to the intruder should be limited within regulatory dose limits. This study conducted the safety assessment of human intrusion on the second-stage surface disposal facility through drilling and post drilling scenario. Results of drilling and post drilling scenario were satisfied with regulatory dose limits. The result showed that post-drilling scenario was more significant than drilling scenario. According to the human intrusion time and behavior after the closure of the facility, dominant radionuclide contributing to the intruder was different. Sensitivity analyses on the parameters about the human behavior were also satisfied with regulatory dose limits. Especially, manual redistribution factor was the most sensitive parameter on exposure dose. A loading plan of spent filter waste and dry active waste was more effective than a loading plan of spent filter waste and other wastes for the radiological point of view. These results can be expected to provide both robustness and defense in depth for the development of safety case further.

Data integration is techniques to combine heterogeneous data from different sources, and to allow users to transparently access all data from multiple sources via a single view. The difficulty with data integration is data heterogeneity (i.e. schema heterogeneity, semantic heterogeneity). Richer semantics of data is a major factor in resolving conflicts among heterogeneous data sources. As UML class model represents only schema-based semantics of data, alternative methods such as ontology is useful for representing additional semantics. This paper proposes a method for integrating two data sources with UML class models by using an analysis of their ontologies. In our framework, ontology will be applied to describe semantics of data in each source. Then the ontologies are analysed and compared to determine their similarities and differences. The result of the comparison is used to devise an integrated ontology that will enable querying on the integrated information.

This study deals with the traffic accident of the Cheongju arterial link sections. The purpose of the study is to develop the traffic accident model. In pursuing the above, this study gives particular attentions to developing the ZAM(zero-altered model) model using the accident data of arterial roads devided by 322 small link sections. The main results analyzed by ZIP(zero inflated Poisson model) and ZINB(zero inflated negative binomial model) which are the methods of ZAM, are as follows. First, the evaluation of various developed models by the Vuong statistic and t statistic for overdispersion parameter ${\alpha}$ shows that ZINB is analyzed to be optimal among Poisson, NB, ZIP(zero-inflated Poisson) and ZINB regression models. Second, ZINB is evaluated to be statistically significant in view of t, ${\rho}$ and ${\rho}^2$ (0.63) values compared to other models. Finally, the accident factors of ZINB models are developed to be the traffic volume(ADT), number of entry/exit and length of median. The traffic volume(ADT) and the number of entry/exit are evaluated to be the '+' factors and the length of median to be '-' factor of the accident.

This study was carried out for analyzing pathological and epidemiological factors of osteoporosis and doing pilot test using trial compounds of tuna bone and oriental herbs based on the factors. Osteoporosis is originated from osteoblast, osteoclast, organic and inorganic factors etc. Therefore the pathology of osteoporosis is not simple because the cytokine, growth factors and hormones of the components are various a lot. Taking a view of epidemiological factors of type I osteoporosis, ageㆍmenarcheㆍcholesterolㆍBMI etc. have definite relation to them. So we can approach to aging or consumptive disease in oriental medicine, specifically differential diagnosis of blood depletion with deficiency of qi, deficiency of kidney, deficiency of yin, bony weakness etc. And it should be considered together with rules for maintaining good health or habit concomitantly. Therefore IL1ㆍ6 or TNF αㆍβ are generally used as molecular biological index for osteoblast and osteoclast because the most important index is bone mineral density and strength, but the factors like collagen and noncollagen protein must be accounted as biomarkers. Trial compounds generally showed favorable effects on accompanying subjective symptoms of osteoporosis in the pilot test for menopausal woman. But if she didn't have specific symptoms of osteoporosis there wasn't any specific change. And osteocalcin was increased in case of being under standard level, but wasn't changed in case of normal level. Therefore these trial compounds can be used as a funcdonal diet for type I osteoporotic patients or preventive measures.

첨단 공정이 필요한 반도체와 LCD, PDP, LED 등의 디스플레이 및 IT 부품을 제조하는데 필요한 장비의 고성능화와 작업환경의 고청정화에 따른 초고진공펌프의 수요 확대와 앞으로 전개될 한-미 FTA에 따른 시장 확대로 인해 크라이오펌프의 국산화가 시급한 실정이다. 고성능 크라이오펌프를 만들기 위해서는 냉각판을 극저온으로 냉각하기 위한 극저온 냉동기 개발도 중요하지만 냉각판(cryoarray)에 최대한 많은 분자를 포획시키는 것 또한 최우선적으로 고려되어야 할 사항 중 하나이다. 이에 본 논문은 크라이오펌프용 냉각판의 기체분자 포획능력에 대하여 연구하였다. 냉각판의 분자포획능력의 해석은 형상계수법(view factor method)을 이용해 수행하였다. 해석에 이용한 냉각판은 현재 상용화된 모델들 중 원형 중앙판에 45$^{\circ}$ 하향 skirt가 달린 형태이며 8장의 냉각판이 일정한 간격을 두고 아래쪽으로 적층되어있고 이를 기본 모델로 하여 skirt의 형상이 다른 3장의 냉각판을 가진 네 가지 모델을 해석하였다. 해석에 이용한 냉각판의 기체분자 포획능력이 구속된 형상에서 얼마나 우수한가를 알아보기 위해 크라이오펌프의 입구 직경과 냉각판 중앙 원판의 직경비, 냉각판 사이의 거리, 그리고 skirt의 길이를 변화시켜가며 극저온 냉각판에 직접 응축되는 typeII가스와 흡착제가 도포된 부분에 의해 흡착되는 typeIII가스로 분류하여 해석을 수행하고 그 결과를 비교, 분석하였다. 크라이오펌프의 입구 직경과 냉각판 중앙 원판의 직경비가 증가함에 따라 typeII가스와 typeIII가스 모두 기체분자 포획능력이 증가하며 극저온 냉각판 사이 거리의 변화에 따른 기체분자 포획능력은 typeII가스의 경우 극저온 냉각판 사이의 거리가 증가할수록 증가한다. 하지만 typeIII가스는 모델 A, C의 경우 증가하고 모델 B, D의 경우 증가하다가 다시 약간 감소한다. skirt 길이 변화에 따른 기체분자 포획능력은 두 가스 모두 skirt 길이가 증가함에 따라 점점 급격하게 증가하고 모델 B, D는 나머지 두 모델에 비해 큰 값을 갖는다. 기체분자 포획능력을 해석한 결과를 실제 배기속도와 비교할 경우 절대적 수치로써의 비교는 어려우나 각 모델의 형상의 차이에 의한 상대적인 비교는 가능하다.

The purposes of this study are to review the status of dress material in the contemporary fashion design by examining the intertextuality of many materials other than textiles used in the contemporary fashion and to show that the development of new fashion materials is a factor for designing competitiveness. The results of this study are summarized as follows: First, foods and natural objects are used as fashion materials to reveal natural beauty, and at the same time new formative elements are expressed in combinations of life and fashion. Second, common paper and luxurious jewelry are presented as a formative element symbolic of an aspect of the contemporary society or embodied in elaborate handicraft techniques. Those materials boost the luxuriousness of costume and create a strong futuristic image according to how they are expressed. Third, plastics available for a variety of objects in different shapes and colors offer such formative features that could be shaped with textiles, as high-end technology is introduced to fashion. Fourth, metallic materials have added freedom to design formality due to their qualities of convergence and displacement and by the introduction of brand-new technology, suggesting a new future for the fashion industry. Fifth, using a variety of anti-fashion materials including semiconductor chips, mirrors, vinyl, wires, and rubber makes a change in the existing points of view regarding the formality of things and helps create a special aesthetic effect in a visual respect to develop a strong intertextuality of materials.
