Recently the demand for civil security and security guards shows rapid growth. However the supply and training system have some limitations. Educational and training systems for civil body and security guards are in the basic level and private organizations trained the professional work force. So this paper is showing what a social dominant factor and a divice of development of the private security. Capitalism is based on a material desire of the human being. the social control of capital value and the management of capital ability reflects the actual condition of the capitalism well. The unconstrained growing and the expansion of capitalism, it finally lost social meaning and an importance of human being element and the safety of the civilian life, began to threat the security of citizen by forming over the material center structure of society. Improving human life quality and material richness on their life leads positive factor of capitalism whereas is causing several crimes through the society which is being threatened around a human being life for a negative factor of the capitalism. Therefore capitalistic social system has offered both a positive factor 'growing' and 'richness' and that of a negative 'structural poverty' and 'lack of security' and they have been remaining the assignment of capitalism 'poverty' and 'security' by settlement in the society for a extremely phenomenon of both sides. In Korea because their recognition of the study approach and the social safety for social security control function is still staying first step and our daily life is annoying from various threat of the society. many studies and the realistic necessity of experience related with social security is being studied. In addition. The development possibility of the civil guard and defense at the civil field which will be keep the social security has a wide position but its study approach and realistic comprehension is still in insufficient condition.

In regard to indoor air quality patterns, the government introduced various polices that were about managing and monitoring quality of indoor air as a major assignment, and also executed 'Indoor Air Quality Management Act' which was presented in the May, 2004. However, among the multi-usage facilities controlled by the Act, the school was not included yet. This study goal was to investigate PM 10 pollution patterns of the high school classrooms using a pattern recognition method based on cluster analysis and disjoint principal component analysis, and further to survey levels of inorganic elements in May, June, and September, 2004. A hierarchical clustering method was examined to obtain possible objects in pseudo homogeneous sample classes by transformation raw data and by applying various distance. Following the analysis, the disjoint principal component analysis was used to define homogeneous sample class after deleting outliers. Then three homogeneous Patterns were obtained as follows: the first class had been separated and objects in the class were considered to be sampled under semi-open condition. This class had high concentration of Ca, Fe, Mg, K, Al, and Na which are related with a soil and a chalk compounds. The second class was obtained in which objects were sampled while working air-conditioners and was identified low concentration of PM 10 and elements. Objects in the last class were assigned during rainy day. A chalk, soil element and various types of anthropogenic sources including combustions and industrial influenced the third class. This methodology was thought to be helpful enough to classify indoor air quality patterns and indoor environmental categories when controlling an indoor air quality.

The current study aims to analyze the process of fabric production planning in Dongdaemun Market, which is a successful model case industrial integration in South Korea. We followed the changes in perception among fabric experts, regarding their recognition of fashion trends, and the following planning and process of fabric production. We used the purpose sampling method to select participants for interview in the Dongdaemun Market, then we carried out one-to-one interviews. Our analysis reveals 4 points of importance. First, the fabric planning stage either employed the trend book swatch, or simply reused the model fabrics already available. Even though the experts felt the need to accept the latest fashion trends, very few considered the trends as positive influences in fabric planning. Whereas trend was a key element in identifying the flow of the fashion industry, there were obstacles in carrying out the study. Second, experts frequently participated in domestic fabric seminars, but not in textile exhibitions. Third, domestic and overseas market research has been performed typically at department stores, and typically at Japan. Fourth, the influx of Chinese fabrics has both positive and negative influences, such as low price, and low reliability. In conclusion, experts were less amenable to accepting the latest fashion trends. pre-requisites in real life to meet the use of the current trend of each company. More studies on the Dongdaemun Market from perspectives of practitioners are warranted.

Background: Alzheimer's disease (AD) is caused by various factors, such as cholinergic dysfunction, regulation of neurotrophic factor expression, and accumulation of amyloid-beta. We investigated whether or not a combination of Carthamus tinctorius L. seed and Taraxacum coreanum (CT) has a protective effect on scopolamine-induced memory impairment in a mouse model. Methods and Results: Mice were orally pretreated with CT (50, 100 and 200 mg/kg/day) for 14 days, and scopolamine (1 mg/kg/day) was injected intraperitoneally before subjecting them to behavior tests. CT-administered mice showed better novel object recognition and working memory ability than scopolamine-treated control mice. In T-maze and Morris water maze tests, CT (100 and 200 mg/kg/day) significantly increased space perceptive ability and occupancy to the target quadrant, respectively. In addition, 100 and 200 mg/kg/day of CT attenuated cholinergic dysfunction through inhibition of butyryl cholinesterase in brain tissue. Furthermore, CT-administered mice showed higher cyclic adenosine monophosphate-response element-binding protein (CREB) levels and lower amyloid precursor protein (APP) levels compared to scopolamine-treated control mice. Conclusions: CT improved scopolamine-induced memory impairment through inhibition of cholinergic dysfunction, up-regulation of CREB, and down-regulation of APP. Therefore, CT could be a useful therapeutic agent for AD with protective effects on cognitive impairment.

디지털 영상은 전송 중에 잡음과 시스템의 다른 요소에 의해 입력 요소가 왜곡된다. 이는 영상객체의 분할시 경계면의 모호함이 발생시키고, 특히 입력 영상 경계 부분은 패턴인식의 분할 및 검출 요소를 결정하기 때문에 매우 중요하다. 따라서 그 경계 부분을 정확하게 분할ㆍ검출하는 최적의 에지 검출 방법을 제안하였다. 본 논문에서는 입력 영상의 임계값에 따른 적응적 형상학을 이용하여 영상의 경계면을 부각시킨 후, 이 영상을 Meyer 웨이브렛-CNN 알고리즘에 적용한 후 최적의 에지를 검출하였다. 제안된 알고리즘이 기존의 영상 에지 검출 알고리즘인 Sobel 에지 검출과 기존의 다른 에지 검출보다 우수함을 확인하였다. 특히 에지와 에지의 부분이 가까운 곳과 완만한 곡선을 가지고 있는 부분에서 더 우수한 결과 에지를 얻을 수 있음을 시뮬레이션에 의해 확인하였다.

This study examined the awareness of the middle aged about the digital home system and well-being apartment design elements in order to suggest the design guidelines for planning of the elderly housing environment. By literature review, the concept and characteristics of the digital home system and well-being Apartment design elements were summarized the degree of satisfaction and preference of middle aged for these characteristics were investigated and analyzed. For this study, a questionnaire survey of 156 housewives living in apartment complex of Busan was carried out. The results of this study are as follows: The middle aged were generally short of recognition for digital skill and service, and also they showed positive evaluations to a few useful items of digital home system. These items belong under safety security system and interior environment control system and provided for convenient & comfortable life. Accordingly, satisfied digital home system can apply basic design element for housing for elderly. Whereas, the middle-aged were not satisfied with housework help system and cultural life system because items of these systems were not various and complicate to us. So, for the improvement of not satisfied digital home system, we needed development of digital contents and marketing & management for high accessibility and easy useability. The middle aged will concern about health & environment friendly continuously and become to stay long in their housing as the characteristics of elderly. So, It is necessary to be considered well-being apartment design elements of health & environment friendly very actively and lastingly in elderly housing environment design. Also, the awareness of middle aged for digital home system and well-being apartment design elements varied according to the background characteristics.

We have attached importance to the values of spirit and immateriality. As the age of modernism of rationality ended, human being began to emphasize spiritual and immaterial while accepting multiplicity and diversification in the whole areas of society and culture. Hence interests have increased in another side of human spirit that was oppressed by rational, analytic, reasonable and scientific thinking, which has expanded the inner world of human being to the world of the unconscious. According to these paradigm changes, steady efforts to improve our lives better both materially and spiritually have been made in the areas of art and design. Therefore, the current study aims to examine the meaning of object expressed in space from the viewpoint of the unconscious, focusing on works of designer Philippe Starck after 2000 in which unique, preferential and liking characteristics are expressed well. Philippe Starck is a designer who connects design with our daily lives and formalizes it with creative ideas. Also the study theoretically explored the theory of the unconscious, a concept of Freudianism, based on 'Meaning of Dreams' of Freud, and explained the expressional characteristics and meaning of unconscious desire through his works by putting object in Philippe Starck's space. It aims to grope for the meaning of object as another possibility that can function as a spatial ruling element by analyzing object through expanding the extent of correlation and interpretation between human containing spiritual things and object which is the recognition subject in space of the present time, not a mere concept as substance like in the past, and expression of Starck's unconscious desire based on unconscious theory.
