This study was to analyze characteristics of fish compositions and longitudinal distribution, based on trophic and tolerance guild at 22 sampling sites of Yeongsan River watershed during 2003$\sim$2006, and also to compare before and after the estuary dam construction. The collected fishes, based on catch per unit effort (CPUE), were 44 species in the watershed and dominant fishes were Zacco platypus, Acheilognathus macropeterus, Zacco temminckii and Carassius auratus. According to comparative analysis of fish in the non polluted sites (NPS) vs. polluted sites (PS), the number of species and individuals was lower by 70% in the PS than the NPS, indicating ecological degradations by chemical pollutions or/and habitat modifications. The relative abundance of sensitive and insectivore species decreased as the stream order increases, while tolerant and omnivore species increased with the stream order. In this survey, largemouth bass (Micropterus salmoides), which is a top-carnivore and exotic species, may influence trophic guild system throughout active predations on endemic species, resulting in modifications of ecological functions. The construction of estuary dam on Yeongsan River in 1981 resulted in wider lacustrine zone and desalinated through limitation of seawater input. These physical changes have caused increases of lentic dwelling species and limited fish migrations (i.e., eel). Overall, fish fauna and composition analyses showed that the number of species and individuals in this water body may be reduced due to inputs of pollutants from the watershed, habitat modifications, and increases of exotic species (largemouth bass). For these reasons, effective lake management strategies are required for the ecosystem conservation.

Purpose: The goal of this research is to create a numerical analytic database that may assist fire prevention managers and building officials in prioritizing items that need to be addressed in order to improve evacuation safety performance while working within a constrained budget and time frame. Method: It was carried out utilizing the CFD Tool, a quantitative evaluation approach, to assess evacuation safety. One direct staircase-type apartment houses and one corridor-type apartment were chosen to make it. Result: In the fire compartment category, Apartment A's evacuation time was around 130 percent longer than that of sprinkler facilities. Conclusion: Fire prevention managers and building officials feel that starting with a single level and implementing "dwelling unit separations" will increase evacuation safety, and that maintaining fire compartments and sprinkler systems at all times will be effective. Because of the limited characteristics of smoke propagation in corridor-type apartments compared to direct staircase-type flats, it is thought that fire extinguishing equipment should be addressed.

What is the meaning of home to older people? How much is home significant for older people? How do they express self-identity through decorating their own homes? These are the new subjects that scholars in the West are involved in lately in terms of micro-perspective (George, 1998; Kellett, Gilroy & Jason, 2005; Gilroy & Kellett, 2006). It is evident that home has more significant meaning to older people than other age groups, since the older are more likely to spend greater time within the home through lower income, lessening mobility or loss of companions (Gilroy, 2005). Also the older tend to cling to their homes and attach to possessions than the younger. Older people's possessions are the things that memories of their lives were absorbed. Therefore, possession display can role as a mean of showing their past lives and memories. Gilroy and her colleagues (2005, 2006) found that there was a certain pattern of possession display in English older people's households, and that older people would like to express self-identity through decorating their own homes with their precious possessions. Then, isn't it interesting to find out if there is any pattern of possession display or decoration items in Korean older people's households as well? Thus, the aim of this study is to describe pattern of possession display as a mean of expressing self-identity in Korean older people's households. Interview with older people was used to find out the way and reason of display possessions. Observation method including taking photos and hand-drawings was also added in order to demonstrate detail condition of display items in the house. Possessions display and furniture arrangement in the living room and bedroom were investigated to find out a certain pattern of display and meaning. Research objects were healthy older people aged over 60, who are living independently from their adult children, and who can manage housekeeping by themselves. 32 households were investigated in the area of Seoul, Kyunggi, Chungchungnam, and Kangwon provinces. The findings demonstrate that most precious possession for Korean older people is photo of themselves; especially one taken in their younger age. The reason of it is because the photo reminds them of their heydays when they were vital. Photo of the most beloved one is displayed more frequently in the bedroom than in the living room indicating consistence with English case. As symmetrical display pattern was dominant in case of English older people's households, no dominant display pattern is found in Korean case. Korean older people also cling to their homes and possessions and want to keep their dwelling space as large as what they use now. It is notable that even after they become older and frail, they want sufficient space to display possessions as a mean of self-identity expression. Attachment to possessions and decoration can give older people significant meaning of identity, and it is the reason why architects or interior designers have to meet older people's needs. It needs consideration that residents are allowed to bring their old furniture and precious possessions when they move in elderly housing unit in order to minimize environmental shock, as well as feeling at home. This subject could suggest a clue to designers or architects who have to meet residents' needs in space design of elderly housing or facilities in the future. Psychological well-being of older people can be met by making them feel at home wherever they live. They need space where they can express their own identity and personality even in case when they have to live in a limited small space like elderly housing unit or nursing home.

Purpose : The system to refer terminally ill patients to palliative or hospice care which ultimately give them emotional, psychological, and social support hasn't been fully developed and organized yet in Korea. The controversies concerning the current referral system are being analyzed to present the improvements. Methods : The questionnaires were asked to be filled out by family members of the 76 patients by phone interview, who were referred from the Seoul National University Hospital between April, 2001 to March, 2002. They were referred to the 35 palliative and hospice care-giving institutes and hospitals which were given questionnaires by mail. Results : Of the 76 patient's family members, 47 family members accepted to answer the questionnaire. The first thing that influence to family to determine the referral of patient was solicitation of doctors or nurses (44%). And they were influenced by allowance for the other things such as convenience of patients (32%), convenience of caring family members (24%). In the course of determining of referred institutes, responders had considered at first their dwelling area, and then fame of institutes, the place which patent had wanted to spend last hours or which is suitable for patient's funeral service, and their financial condition. Thirty-eight the 47 responders answered that they had experienced difficulties in referral procedure. The worst among difficulties was unwanted discharge, and followings were lack of information about the referred institutes, concern about patient's suffering, resistance of patient and opposition of other family members, etc. Although they expressed dissatisfaction in referral procedure, most of them answered they had been satisfied with hospice care at referred institute after referral. Merits of referral which responders counted were patient's peace, caring family's comfort and reduced cost in order. Of the 35 referred institutes, 24 institutes' staffs responded mail questionnaires and sent to us in return. Except one responder, the rest approved the referral system and thought that referred patients had been satisfied with their hospice care. And they claimed that systemic support of the government is definitely necessary. The most difficult thing which responders experienced in care of referred patients was lack of information about patients. Besides, there were patient's financial problems, lack of understanding about their institutes of patients or family, and inconvenience of terminal cancer patient's pain control. Conclusion : The development and support of the organized referral system is needed to alleviate the troubles which patients, family members, and palliative or hospice institutes and hospitals have to face through the procedure of the referral.
