최근 자동차에서 위치$\cdot$지리정보를 제공하는 CNS(Car Navigation System)분야로 많은 개발이 되고 있으며, 이를 휴대용 단말기에 적용해 개인화하여 서비스를 제공하고 있는 추세이다. 휴대 단말기에 적용해 개인화 서비스를 제공하는 것을 PNS(Personal Navigation System)라 하며, 이 시스템은 이동 중인 사용자가 휴대용 기기에 공간 데이터를 저장하고 사용자의 위치를 기반으로 목적지까지의 경로를 안내하는 서비스 유형으로 사용자가 휴대하는 기기에 의해 정보가 제공되기 때문에 개인화 정보 제공이라는 특징을 가지고 있다. 또한 위치기반 PNS 서비스는 단순 위치 정보의 활용만이 아니라 위치 정보를 근간으로 POI(Poin of Interest)가 제공되어야 한다. 이를 위해서는 위치에 부가되는 다양한 POI의 정보와 함께 개인의 성향 정보가 적용되어야 한다. 그러나 아직까지 개인의 성향이나 특성에 따른 정보를 포함하지 않고 있다. 본 논문에서는 사용자가 선 입력한 성향정보와 History 정보로부터 추출되는 사용자 선호 특성 정보를 데이터베이스로 구축하고, 개인 선호 특성 정보를 반영하여 웹 또는 모바일 기기를 통해 POI 서비스를 제공 받을 수 있는 PNS시스템을 제안하였다.

The study is based on the serious environmental problems occurring these days to acknowledge the consumers awareness and preference according with the coordination using recycled materials in the dining space. As the result, considered the consumers had lack in recognition of using recycled materials when they tried to use them in their normal daily life. Also the females were far more interested than the males with the usage of the recycled materials inside the restaurant and its interior image along with married persons had more positive attitude towards it than the unmarried ones. With education back ground, highly educated peoples really quite didn't prefer the usage of the recycled materials. According with the income, the high earnings and with the occupation, the professionals with specialized jobs considered the practical use of aspects more important than above. Therefore the needs to educate and promote the consumers to use recycled materials in their every day lives, it is required to build social responsibility and finding the essential meanings to save resources so that they can utilize them with converted recognitions.

유비쿼터스 상거래의 도래에 따라 개인화 된 서비스를 위한 상황과 환경 정보 즉, 컨텍스트 정보에 기반한 정보 제공의 중요성이 높아지고 있는데, 기존의 연구는 물리적 환경에 국한하여 컨텍스트를 적용하고 있으며. 개인의 선호를 고려하지 않는 타켓 마케팅 개념적 서비스에 기반을 두기 때문에 유비쿼터스 상거래 환경의 컨텍스트 도메인 관점에 부 적합하고, 개인화된 서비스 지원이 어렵다. 따라서 이 연구에서는 유비쿼터스 환경에서의 컨텍스트 개체에 대해 정의하고, 전자공간과 물리공간의 연계를 바탕으로 실세계의 일반화 된 공간 개념과 전자 공간의 카테고리 형태의 구조를 통합한 개념 계층 구조로 컨텍스트 정보 모델링을 제안하고, XML 데이터베이스를 이용하여 설계한다. 아울러 이렇게 확장된 컨텍스트 개념을 기반으로 적용 가능한 개인 상거래 서비스를 설명한다.

The purpose of this study is to analyze the current status of space use in university library and draw up considerations for enhancing space utilization based on the analysis results. For this purpose, the utilization rate of each space was analyzed by categorizing the user's space of the university library, and secondly, the preferences of the major user groups were analyzed according to the characteristics of the users' space. For empirical analysis, we collected and refined users' space usage data (98,282 people's data 433,769 cases) accumulated for one year for the central library of "J" National University. Then we analyzed the usage pattern according to space and period(monthly, hourly). In addition, preferences for each major group of users (undergraduates, graduate students and graduates) in the library were analyzed through the library visitors' data (2,426,553 cases) over the same period. The results of this study can be used as preliminary research for the composition and arrangement of users' space in future university libraries.

This study analyzed the differences of tableware and garnish decoration in color and material by conducting a content analysis of 1,357 pictures from food-styling magazines and a survey of 84 restaurants in Seoul. The data used for the study were collected from Cookand and Best Home Magazine and the survey results of the restaurants. Results of the study were as follows: First, both food coordinators and upscale restaurants preferred porcelain while low-priced restaurants tended to use plastic as materials. Second, the preferred color of tableware was white as it is believed to represent the image of neatness and purity. Therefore, food coordinators prepared food in magazines for food-styling and upscale restaurants using white porcelain tableware, and low-priced restaurants also did using white plastic tableware. Finally, the preferred color of garnish decoration was green. Most professional food coordinators tended to use red and green colors to emphasize the combination of complement colors, and some expensive restaurants used five garnish decoration colors.

To find out characteristics of TV home shopping's virtual space deepness styling, this study had analysis characteristics of space deepness which is showed on flat TV screen with actually aired 6 dinnerware sales case, at $C^*$ home shopping, March.2005~November.2010, and survey consumer's emotional verbal image according to space styling character to get space deepness, which were shown on flat TV screen with camera angle, and research mutual relation with consumer preference. Also consumer's typical emotional verbal images for each space styling images for brand dinner ware sales had been extracted with reliability analysis, factor analysis, and multi dimensional scaling MDS using SPSS. Styling characteristics of space deepness were contrast of size, layering, vertical arrangement, and perspective arrangement, and used camera angles were bird's eye view, hi angle, and eye level. Result from the research is, highly marked consumer preferred styling material had a deep corelation to material's main factor and perceived emotional verbal images. Therefore this research could bring forward to new consumer preferred styling characteristics according to camera angle. Furthermore, it will be possible to make a study of preferred styling material through evaluation of quantitative spectators of in this area.

Currently, urban regeneration is carried out mostly in a permanent and fixed way of planning, and due to the nature of the master plan, it is limited to immediately accepting the opinions of residents. In this study, the factors of idle space were derived based on a temporary use strategy, and the direction of idle space was presented by comparing the importance of experts with the survey of residents' perceptions and preferences. As a result, residents preferred to improve the aging physical environment first because of the target location characteristics, while experts ranked it in line to reflect the importance of the use of temporary uses that can quickly improve the urban environment. Therefore, it is desirable to recognize the importance of the temporary use strategy and to refine the priorities of the two groups and conduct a temporary test to derive the optimal utilization measures and reflect them in the master plan. In order to implement a temporary use strategy in the future, it is necessary to present a space utilization plan that reflects detailed prior investigation through analysis of target location characteristics and usage patterns.

The purpose of this study is to suggest the objective basic data for applying to development and conservation management of the national park through the quantitative analysis of the visual quality included in the and physical environment of the Tokyusan National Park. For this, spatial images and structures, of natural elements have been analyzed by factor analysis algorithm, and degree of visual quality has been measured mainly through questionnaries. Result of this study can be summarized as follows. Factors covering the spatial image of the Tokyusan National Park landscape have been found to be the overall synthetic evaluation, appeal, spatial, natural quality and dignity factors such as the overall synthetic evaluation, spatial and appeal yield high factor scores. The main factors determining the degree of visual quality are the clearness valley, peculiarity of configuration, natural of trail, harmony of suitable artificial planting and temple.
