외부 환경에서의 영상처리 기술은 환경에 매우 민감하여 외부환경이 급격하게 변화할 때마다 정확도가 많이 떨어지는 경향이 있다. 본 논문에서는 다양한 변화가 일어나는 실외환경에서 영상처리 기술을 이용한 방범용 차량 검지 및 추적 시스템을 제안한다. 방범용 카메라검지기는 하나의 차선내에서 차량을 검지하고 추적하기 때문에 차량의 윤곽보다는 차량의 특징 영역을 분리하는 것이 중요하다. 제안한 시스템은 차량 진입의 판단을 광류를 통하여 검지하며, 차량의 전조등, 본넷, 전면창, 루프 등으로 영역을 분류하여 차량을 추적한다. 실험을 통하여 제안한 시스템이 차량의 종류, 속도 및 시간 의 환경 변화에도 강인함을 확인하였다.

The purpose of this study was to investigate the preference determinants of buddhist temple food(BTF) and leaded to its activation based on these results. 354 subjects were participated in the survey using questionnaires. 66.9% of subjects had over the normal interest. The taste of BTF was light(34.7%) and it would be helpful in their health(72.9%), subjects answered. Lightness and not strong taste was the main reason of preferring BTF(50.8%), but lack of nutrients was dislike reason of BTF generally. According to factor analysis, the factors of preference determinants deduced as the external form, social environment, health, essential quality and information of food. There were not significantly different between factors by sex and family form. External form, health and essential quality of food had the significant difference by generation and education level. The factors of external form and the essential quality of food showed the significant difference by job. According to the monthly income, the factor of social environment, health and information of food had the significant difference.

This study examines the differences in the various characteristics of the firms along their growth stage based on the survey data of 2,515 Korean ventures. Venture characteristics include KSFs(Key Success Factors), environment attributes of their product markets, CEO roles, the use of OPR(Other Peoples Resource). Growth stage of the ventures are classified by their dominant management problems: foundation, the market launch of the first proprietary product or service, The Outset of second generation product or service, and the Initial Public Offering (IPO) and stabilization. The results of this study show substantial differences in many aspects among firms at different growth stages. Although common KSFs exist, KSFs are changing as the venture evolves. Differences in KSFs and environmental attributes along growth stage require CEO to do different role in business process. Different kinds and amounts of external resources are needed according to their growth stage. However, almost all of external resources are offered to ventures in later stage. Entrepreneurs need to change their role, as their firms grow, from visioning and strategic role to marketing and production emphasized role. Based on the results, this study suggests a number of new government policies and future research ideas. Other implications and limitations of this study are also noted.

The uptake of $^{14}C$-2, 4, 6-trinitrotoluene (TNT) in hydroponics was studied using onion plants. Of the total TNT mass (5 $\mu\textrm{M}$ concentration), 75% was in the roots, 4.4% in the leaves, and 21% in the external solution at 2 days, The percent distribution in roots was lower with higher concentration in the external solution, but in leaves it was comparable at all concentrations (5-500 $\mu\textrm{M}$). Root concentration factor (RCF) in hydroponics was more than 85 in constant hydroponic experiment (CHE) at 5 $\mu\textrm{M}$ and 150 in non-constant hydroponic experiment (NHE) at 5 $\mu\textrm{M}$. The maximum RCF values in the hydroponic system were greater with lower solution concentration. Transpiration stream concentration factor (TSCF) values in the present study (NHE only: 0.31-0.56) were relatively similar to the values with predicted values (0.43-0.78), increasing with higher external TNT concentration. For phytotoxicity tested in hydroponics and wet paper method, 500 $\mu\textrm{M}$ was toxic to onion plant, 50 $\mu\textrm{M}$ was non-toxic for plant growth but limited the transpiration rate, and 5 $\mu\textrm{M}$ was non-toxic as control.

Purpose: Recently, Housing area plan has tried to reflect a public space of various forms. However, most of cases are indiscriminately developments, which don't reflect the diverse needs of residents. In addition, a subject of the public space is not clear and consistently stable of the management, so the residents don't have an interest enough to take advantage of it. Method: In order to make a plan of the public space of a residential complex, an architect designer needs to take a few things into consideration. One is a physical facility in needs. And other one is a management of keeping a social place stably and consistently, which allows residents to be able to interact with each other. It should be regarded for residents to form a sense of belonging, while minimizing the interface friction. When all these problems are fulfilled, an interaction will be made to improve the quality of the living environment. Result: Therefore, in this study, it is necessary to define the meaning of territoriality of the external public space of housing complex. This study makes it possible to improve the relationship of neighborhood and the quality of the life for the residents, depending on the time. This is the first step as 'the research for the territoriality of the external public space of housing complex', in order to define about the concept, function, characteristic of territory(the base of territoriality) and to establish the territoriality that can form the physical or psychological boundary in public space.

The purpose of this study is to investigate residents subjective opinion of the noise on the low-rise multifamily house in U.S.A. The results of this study can be applied for the prevention of noise when planning cities, roads, and multifamily houses in Korea. The subjects of this study are three kinds of multifamily houses and their 109 residents in Athens, U.S.A. The results of this study are as follows. The residents felt the noise from lawn mowers and the sound from filter fans of air conditioners were higher than in the other external noise. The residents daily activities were disturbed a little by the external noise. Of the internal noise, the air home sound was recognized a little by residents. They only felt a moderate sound level from the building services of the solid borne sound. They suffered worse from noise in the summer and they felt worse from 16∼20 o'clock due to noise. The residents who were living in town houses felt better than those in the other multifamily houses. (Korean J Human Ecology 1(2):61∼74. 1998)

This study comparatively analyzes the cases of CDMA (Code Division Multiple Access) and WIPI (Wireless Internet Platform for Interoperability) to find out the success and failure factors of technology policies in the field of mobile communication industry. For this purpose, the two cases are analyzed through a new analysis framework, which is made by combining System of Innovation with a range of variables derived from precedent studies, such as external environment, institutions, technological system, governance structure, and interactions of actors. The results of analysis show that in the CDMA case, the following factors led to success ; Korea made good use of the external opportunities in the early stage of digital communication technology and adopted a suitable governance structure for the technological system. Main actors in Innovation System had strong will for success and engaged in cooperative interaction. For the WIPI, however, the timing of technology policy was inappropriate and a unsuitable governance structure for technological system was chosen because of path dependence. The Innovation System failded to respond efficiently to the situation where conflicts among actors had intensified, US trade pressure had increased and innovative smartphones emerged. The results of this study provide the practical implications for the success of technology policy; namely it is important to choose a governance structure that suits the external environment and characteristics of technology and to activate cooperative interactions among actors in Innovation System.
