This study investigated the perceptions toward the elderly of elementary school children in Incheon area. The subject of this study were 264 elementary school children in grade 2, 4, 6 and their mothers. Instruments included the inventory of the perceptions toward the elderly. The main results obtained from this study were as follows The degree of children's perceptions toward the elderly differed according to children's sex, age, birth order, mother and father's education, income of the family, religion and the attitudes of parents toward the elderly. Also the degree of children's perceptions toward the elderly differed according to whether grand parents are alive or not, whether they live together in the same household or not, the age of grand parents, their financial ability, health of grand parents.

Turning into the 21st century, there are great demands for the diversification of housing style and amenity of housing, which include enhancing community life through proper collective environment. To solve these problems, cohousing has been introduced in Scandinavian countries. A primary goal of cohousing is the desire of residents to live in a socially supportive setting. People can do housework together and also can promote active mutual relationship among residents in the community. Physical feature of cohousing, in combination with social organization factors, nay serve to enhance or support the sense of community sought by residents. In this point of view, the purpose of this study is to consider the characteristics of planning factors applied to the community concept in cohousing. First consideration is to figure out the planning skills on community concept in housing community. Then, by making clear the planning factors on community concept in cohousing through case study, this paper could suggest a possibility of application of cohousing in Korea.

Periodontitis is a multi-microbial disease and the comparison of a series of periodontopathogenic and non-periodontopathogenic bacteria in terms of microbe-host interaction may provide clues to understand the microbial etiology of the disease better. When we deal with twenty different bacterial species in a study, the first technical issue is how to measure the accurate concentration and use the same number of bacterial cells. We measured bacterial concentration by enumerating bacteria stained with SYTOX green for constant time using a flow cytometer and compared the results with those obtained by plate counting. Concentrations calculated by two different methods were very close. Therefore, flow cytometric counting allowed the rapid analysis of live/dead bacteria, offering the advantage of turbidity measurement and that of colony counting together.

The purpose of this research was to test multiplex polymerase chain reaction in investigating the microbiological quality of the risky surfaces in social living places of a military base where over 15 thousand people live together. In 22 samples of 99, there were no bacteria. Only four of the samples contained Shigella, and one of them contained Salmonella, but 77 of the samples contained thermotolerant coliform organisms. There was no statistically significant difference among the microbiological quality of different sites and different equipment surfaces (p>0.05).

The biotin-attached G8 molecular transporter (5) was synthesized and used together with quantum dots in preparing the complexes (QD-MT). The QD-MT complexes were studied in terms of the cellular uptake and the internalization mechanism in live HeLa cells with the aid of various known endocytosis inhibitors. It has been concluded that the QD-MT complex is internalized largely by macropinocytosis. The mouse tissue distribution of the QD-MT complex by i.p. and i.v. routes showed some organ selectivity and a good ability to cross the BBB.

Modernity which is superficial phenomenon set off the mass scale for mass consumption and provide uniformly artificial environment. But natural destruction, environment pollution, resources exhaustion and so on has been caused by this and now ecology is threatened by destruction and damage beyond the limitation and human beings survival is even threatened. Accordingly furniture development for environment preservation considered environment problem is the urgent real situation. Recent paradigm is the concept of Eco-design which is the green design possible to live together in symbiosis, and new types of alternative furniture are needed in Korea as well. 'Furniture for disassembly' is presented as new method for alternative furniture.

Aging society appears immediate social problem in Korea. Housing for aging is required independent and comfortable housing life to live considering about feature of elderly. It is necessary field to prepare. Aged person who suffers the aging process several stages gets changing weak, so living environment is important aging person aspect of social, psychological and physical point. Finally, aged person living together requires facilities for the naturally communicating and active things. Community of aged person required organization of space for keeping independence and connection with each other. According to space of community, housing for aging should have a different access route. In conclusion, congregate housing of the elderly should be planed organization of space to be solved anxiety and tension and to be aware of joining the community.

The proliferation of the House Dust Mite(HDM) is affected by temperature, humidity, ventilation, etc. Measuring temperature and humidity was performed at the very location where dust samplings take place and where they live in reality together with temperature and humidity of the ambient of the room. There has been discussion over the key environment factor of HDM survival; absolute humidity or relative humidity. It seems that relative humidity is the more important determinant for the mite's survival through the analysis of previous studies. Temperature, humidity, ventilation rate and Der P1 were measured in 4 flats in London. Mite allergen was detected in every house. Levels of Der P1 varied between <100ng/g and 22,778ng/g. Flats with high relative humidity(>50%) and poor ventilation(<0.5ach) showed higher levels of mite allergen than flats with lower humidity and adequate air change rate. Questionnaire survey was conducted and the result helped to confirm the findings from monitoring of environmental factors and the dust sampling.

The purpose of this study is to offer and analysis the stage of elderly in order to improve the quality of living environment of elderly in Korea. The results are as follows: Stage 1 of the early elderly appear to live with the elderly and their children, but stage2 and stage3 show the increase of the elderly couple. In case of elderly household, It showed reasons of living together, relationship between the elderly and their children for taking care of grandchildren and being dependent children. Also, residents currently had lived for a long time, especially get older, and ageing in a place has definitely. The Stage of elderly can be applied to understand the living environment for elderly in the future when housing for elderly solve a problem.

A number of previous researches in evolutionary algorithm are based on the study of facets we observe in natural evolution. The individuals of species in natural evolution occupy their own niche that is a subdivision of the habitat. This means that two species with the similar requirements cannot live together in the same niche. This is known as the competitive exclusion principle, i.e., complete competitors cannot coexist. In this paper, a new evolutionary programming algorithm adopting this concept is presented. Similarly in the case of natural evolution , the algorithm Includes the concept of niche obtained by partitioning a search space and the competitive exclusion principle performed by migrating individuals. Cell partition and individual migration strategies are used to preserve search diversity as well as to speed up convergence of an ...
