The way of the life of urban poor including their health behavior can be well explained by structuring how they maintain reciprocal relationship in their intimate social network. In this paper two hypotheses are proposed: 1. Social networks duly exert influence on the health behavior of the urban poor. 2. Through the study of how existing social networks influence health behaviors, a peripheral network model can be utilzed to improve the unequal state of health problems within their socio-cultural context. In a network each inhabitant's dyadic relationship may be described by its intensity of reciprocal exchange. This intensity of reciprocal exchange depends on four factors: 1) formal social distance 2) physical distance 3) economic distance 4) psychosocial distance 5) psychosocial distance (Lomnitz, 1977) In the research area kinship networks exert strong influences on the inhabitant's life defining formal social distance, and neighborhood networks also have strong reciprocal relationship as do physical distances. This is because factor 1 and factor 2 overlap in many cases (See Figures 2 and 4). In other words, those who migrated to the urban area with the help of their precedently settled-down relatives, naturally live near those relatives(See Table 2.) In economic distance kinship networks also exert a strong influence. For example, in case of B3(Figure 3), who is running a subcontracting factory of hand knitting, all ten girl employees are his relatives or girls, from his own local area. Psychosocial distance is subordinate to the above mentioned three distances. Relationships for sharing joy or sorrow when relatives, neigbors or friends, having wedding ceremonies, birthdays, funerals and other rituals, are dependent on formal social distances, physical distances and economic distances. The stronger the psychosocial distance becomes, the closer a network becomes. In the research area the above mentioned networks exert influences when health problems occur (See Fig. 5 and Table 6). There are several formal networks in the reseach area, Tongjang-Banjang, Saemaeul Women's club, School Mother's club, Minjeong-dang Political Member Committee and etc. After reviewing these networks using the four factors, the researcher proposes that the Tongjang's family and Banjang's family can be the nodes of the peripheral network which can be utilized to improve health problems in the area of urban poor. The theoretical backgrounds are as follows: 1. As formal social distance the inhabitants and Banjangs are very close because of monthly "Bansanghoe" meetings, chennels of much registration work and information between the dong office and inhaitants, and recommendation for a medicaid card by Tongjang and Banjang. 2. As physical distance, a Banjang who is covering only 23 households or 8 houses on the average has many physical contacts with the inhabitants. 3. As economic distance the distribution of Banjangs' job shows that he/she may have many chances to contact inhabitants by their daily economic needs(refer to Table 7). 4. As psychosocial distance there is a good example in 1st Redevelopment Area. Some residents manage a charcoal briquet shop and give a small portion of the profits to any resident who has good or sad affairs, with Tongjangs and Banjangs as the central figures. (Table 8 shows familiarity of Banjangs). 5. Tongjang and Banjang are usually men, Consequently there-may be some problems in the communication of the M.C.H. programme. However, as their families can also work as the nodes of network, their wives or daughters can be used to support the programme. To approach P.H.C.(Primary Health Care) for the urban poor effectively, cooperation with the community is an essential factor. Therefore, it is suggested that the Tongjangs' and Banjangs' family be used as nodes of network as a mechanism to utilize the principles of P.H.C. in Guro 6 Dong.

Ultra high molecular weight polyethylene (UHMWPE) containing benzophenone (BP) is photocrosslinked under continuous UV irradiation. BP addition as low as 0.77 mol% per repeating unit of UHMWPE is enough to increase the gel fraction up to 99.8 %. The crosslinks are formed through the recombination of methine radicals generated from the hydrogen abstraction of UHMWPE by the excited BP. The heat of fusion of UHMWPE reduces substantially and the peak decomposition temperature increases as much as $15.8^{\circ}C$ due to the crosslinked network, coupled with slight decrease in crystallinity. The tensile strength, modulus and toughness of the crosslinked UHMWPE film are significantly improved with increasing crosslinking density. The wear rate of the UHMWPE also remarkably decreases from 10.2 mg/million cycles to 1.9 mg/million cycles, which can minimize the wear of total hip joint anthroplasty bearings.

Urban regeneration projects are in the spotlight as new urban countermeasures that go beyond the existing era of urban development, redevelopment and reconstruction. Urban regeneration, which made full use of regional context, past heritage and history, and local resources, has a clear distinction from urban development and redevelopment strategies that have created uniform landscapes. The Seoul-type urban regeneration project, which used to be centered on Seoul City, was implemented, and the Ministry of Land, Infrastructure and Transport also spread to nationwide projects through the urban renewal New Deal project. Urban regeneration projects are carried out in several types. It refers to the classification of neighborhood units, central urban units, and economic-based units, which can be called an attempt to reflect the key characteristics, spatial hierarchy and uses as much as possible. In particular, in the case of metropolitan and provincial governments, basic and strategic plans are needed to ensure that urban regeneration projects within local governments have interconnection and organic cooperation systems, which is the urban regeneration strategy plan. In this study, Uijeongbu City, which is connected with Seoul Metropolitan Government and is being revitalized, will be selected as a research site to reconstruct urban renewal planning elements based on relatively important planning elements and to use them as a practice model for strategic planning. Through this, the research will be conducted to reflect the narrow process so that urban regeneration in Uijeongbu can be a practical plan considering the importance of policy. I would like to propose a basic urban regeneration model that reflects the demand for urban regeneration by various entities that make up Uijeongbu City, including citizens, government officials, experts and politicians.
