The increase of impervious cover (IC) in a watershed is known as an important factor causing alteration of water cycle, deterioration of water quality and biological communities of urban streams. The study objective was to assess the impact of IC changes on the surface runoff characteristics of Kap Stream basin located in Geum river basin (Korea) using the Storm Water Management Model (SWMM). SWMM was calibrated and verified using the flow data observed at outlet of the watershed with 8 days interval in 2007 and 2008. According to the analysis of Landsat satellite imagery data every 5 years from 1975 to 2000, the IC of the watershed has linearly increased from 4.9% to 10.5% during last 25 years. The validated model was applied to simulate the runoff flow rates from the watershed with different IC rates every five years using the climate forcing data of 2007 and 2008. The simulation results indicated that the increase of IC area in the watershed has resulted in the increase of peak runoff and reduction of travel time during flood events. The flood flow ($Q_{95}$) and normal flow ($Q_{180}$) rates of Kap Stream increased with the IC rate. However, the low flow ($Q_{275}$) and drought flow ($Q_{355}$) rates showed no significant difference. Thus the subsurface flow simulation algorithm of the model needs to be revisited for better assessment of the impact of impervious cover on the long-term runoff process.

This study was a survey done for the purpose of constructing a nursing theory according to Korean culture and to identify the traditional Korean view of humans and the expectations of the sick role, and to confirm changes from the traditional view of humans and expectations of the sick role according to general characteristics of the population. The subjects were all adults over 18 years old. 517 who lived in six large cities and 191 who lived in five rural communities. Data collection was done from November 19th, 1994 to January 19th, 1995 using a tool to measure the traditional view of humans and expectations of the sick role which was developed by the investigator through a literature review. Collected data were analyzed using frequency, percent, Cronbach alpha, 1-test, F-test and Scheffe post hoc contrasts, with the SAS program. The results of this study are summerized as follows : 1. The Traditional view of human score for all subject was 49.92, which shows that Korean traditional view of human is moderate. High scored items were "human need to live by making harmony with nature, not by overcoming the nature" (3.44), "Filial duty to parents and elders is important" (3.31), "Think of family more than a individual" (2.96). 2. The differences in the traditional view of humans between residential districts showed that the residents of Chungbuk(56.00), Kyungbuk(55.26), Chonbuk(51.32), Taegu(50.59) had a more traditional view of humans than those in Pusan(45.42) and Seoul (47.27). 3. The differences in the traditional view of humans according to general characteristics showed that rural community residents, males, older people, people with lower levels of education, married and house-resident groups had a significantly higher traditional view of humans than urban residents, females, younger people, people with a higher levels of education, single and apartment-resident groups. There were differences according to religion and job. Buddhism had a higher traditional view of humans than those of atheism, Christianity and Catholicism and physical workers, a significantly highers score, than technicians and professional workers. 4. Daily expected task performance during illnesses was lowest for patients with stroke (2.16) and psychosis(2.40), in which case almost no daily general tasks were expected, followed by arthritis 4.06, peptic ulcer 4.79, headache 4.99 and cough 5.58. The amount of expected role exemption during illnesses was also highest for stroke(2.25), followed by psychosis(2.08), arthritis(1.64), peptic ulcer(1.29), headache(1.16) and cough(1.09). The amount of daily task performance in the acute stage(3.05) was significantly lower than that of convalescent stage(4.95). 5. Total expectation of role exemption according to general characteristics showed that there was no significant differences in urban /rural community, marriage, level of education and religion. By sex, women showed higher expectation of role exemption during illnesses than men. By age, the 31-40 year old group showed lower expectation of role exemption than the 41-50 year old group or over the 61 year old group.or over the 61 year old group.

This is a study for the construction of nursing care based upon the Korean attitude toward medicine. Factors which were investigated include the source of nursing care, the reason for choosing care, the type of heath care chosen, the accessability of caregivers, and the desired location of death. The population examined in this study consisted of 517 adults distributed in six large cities and 191 adults from five rural communities. Data was analyzed using frequency, percent, Cronbach alpha, $X^2$ - test, t - test, F - test and scheffe post hoc contrast with an SAS program. The results of this study are summarized as follows: 1. Among sources of nursing care used, first rank rated-pharmacy(54.4), private hospital(18.2), general hospital(8.4), folk remedies in house (5.0), chinese hospital(2.8), prayer(2.8) and others(8.4), and the reasons for choosing nursing care rated 'the easiest method' (63.6), 'the best method'(15.7), 'reliable'(10.8) and 'lower cost burden'(4.6) in order of preference. 2. The type of nursing care chosen rated western medicine(6.80), chinese medicine(6.15), folk remedies(5.46), faith remedies(3.51) and divination remedies (1.41). There were significant differences in the effect recognition degree to various kinds of medicine. 3. The difference of the type of nursing care chosen according to general characteristics showed that urban residents were higher than rural community residents(t=2.15, p=0.0320) in western medicine, and urban residents, women, and singles were higher than rural community residents(t=2.04, p=0.0414), men (t= -2.89, p=0.0039), and married(t=2.50, p= 0.0126) on folk remedies. With repect to age and education those 21-30, under 20 and 31-40, graduated from college and graduate school were higher than above 51, above 61 (F = 7.76, p = 0.0001), graduated from elementary school(F=4.39, p=0.0006) on folk remedies. In other categories, rural community residents, women, younger people. Christians were higher than urban residents ( t = -2.73, p=0.0305), men(t= -4.15, p=0.0001), older people (F=2.48, p=0.0307), Catholic, Buddhist, or atheist (F= 70.18, p=0.0001) on faith remedies. Those graduated from high school and Buddhist were higher than unschooled, graduated from middle school(F=3.18, p= 0.0075), atheist, Catholic or Christian(F=18.32, p=0.0001) on divination redemies. There were significant differences concerning age and education level. 4. The accessibility of caregivers rated 'caregivers should be nearby if the patients need them' (50.0), 'caregivers must be there all day (24 hours)' (39.6), 'caregivers must be there at night only'(5.0), 'caregivers must be there during the day only'(2.6), 'caregivers always should visit during visiting hours' 0.4), 'caregivers don't need to be there at all' (1.2). The frist rank of suitable caregivers were rated as spouse(66.6), mother(24.2), daughter (3.6), daughter-in-law(1.9), and the reasons of thinking thus were rated as 'the most comfortable' (81.5), 'people should correctly with regards to family they'(7.1), 'the easiest' (5.4), 'take good care of the patient' (5.1) and 'lower cost burden' (0.4). 5. The desired location of death rated as the following: his/her house (91. 6) to the hospital(8. 4). A person going to encounter death in the hospital wanted his house(78.5) over the hospital(21.5), and a person dieing in the hospital prefered his house(52.9) over the hospital(47.1) as a funeral ceremony place. The following suggestions are made based on the above results. 1. A sampling method that enhances the re presentativeness should be used in regional and/or national related research and replicated to confirm the result of this study. 2. This study should be used to understand the Korean view of medical centers and to meet the expectations of patients in Korean nursing. 3. Research on the Korean traditional view of humans and expectations of the sick, health and illness, and health behavior, the perception of dying, the decision to heal, and the view of general medicine should continue to be conducted continuosly so that Korean nursing theory can be advanced on these concepts.

This study was conducted to examine the inhabitation of wild birds at the World Cup Park and to offer the Park ecological management data. Land use md actual vegetation were examined to analyze the inhabitation of wild birds. Characteristics of bird communities were analyzed by dominance, density, diversity index and guild concept. You compare inhabitation before and after the Park was built. We classified the land use and actual vegetation into twenty-six types. Robinia pseudoacacia dominated the study area. Pyeonghwa Park and Nanji-cheon Park were simple-layer structures composed of alien woody species. The observed birds after the World Cup Park included 33 families 77 species, and 9,751 individuals. Among Wild Life types, the shrub and bush type was dominant. There were 26 species of resident birds, 20 species of summer visitors, 18 species of winter visitors, and 12 species of passage migrants. The following numbers of species and individuals were observed: in Hanul park, 38 species, 3,151 individuals; in Noul park, 45 species, 2,061 individuals; in Nanji-cheon park, 42 species, 2,742 individuals; in Pyeonghwa park, 29 species, 875 individuals; and in Maebongsan(Mt.) area, 35 species, 922 individuals. Species diversities for each area were as follows: Noul park, 2.613; Hanul park, 2,301; Nanji-cheon, 2.228; and Pyeonghwa park, 2,019; and each season: summer, 2.652; spring, 2.650: winter, 2.561; and autumn 2.176. The diversity of species increased from 1.135 in 1994 to 2.324 in 2001. We recommended that the park be differented into different ecological areas in order to encourage the appearance of wild birds at the World Cup Park. The management area was divided into three districts(conservation area, preservation and restoration area, use area). The conservation area was established to the west of a waste landfill and in the downstream area of NanJi-cheon, the preservation and restoration area was established in the midstream area of Nanji-cheon, and the use area was established in the buffer zone of Pyeonghwa Park and the Nanji pond greenspace.

The purpose of this study was a biota research and analysis for Close-to-nature stream restoration planning of Shinchun. The summary of this study is as follows; 1) The vascular plants in research area recorded of 45 species and insect fauna recorded of 34 species of 8 orders. As a result of table of community classification, the communities were two group; Quercus variabilis community(I), Pinus densiflora-Quercus variabilis-Quercus dentata community(II). 2) As a result of analysis on correlation of tree species, the level of significance in positive correlation between Quercus dentata and Corylus heterophyll aindicated 1% and between Pinus densiflora and Lespedeza bicolor also indicated 1%. 3) As a result of DBH analysis, it is expected that Quercus variabilis and Quercus dentata will dominateover other species in competition and its succession continuously maintains from now on in community I. In community II, it is assumed that there is a high possibility of changing into community of Quercus such as Quercus mongolica, Quercus dentata, and Quercus variabilis. 4) As a result of analysis on insect fauna, insect fauna consists of 94% of whole species as 32 species, 23 families, 8 orders. And 7 species, 7 families 4 orders was found in highly urbanized area, the vicinity of Sang-Dong bridge. 5) As mentioned above, Based on A biota fundamental research, Close-to-nature stream restoration planning were full of suggestions: i) Designating ecosystem preservation area, ii) Making Close-to-nature stream revetments, iii) Making pool-and-riffle, vi) Making decks for observation and walks for nature experience, v) Creating wetland biotope. Through these methods, it is necessary to promote bio-diversity and lead people to the space for eco-learning.

The ecological background of a restoration project is complex and difficult to betermine without experimentation. A useful context for experiments is the well-studied process of natural succession, because the factors that drive or inhibit succession are also at work during reclamation (a form of primary succession) and restoration (which often resembles secondary succession). Using experimental studies on urban wasteland reclamation, we have tested for factors that stimulate or inhibit succession during early phases of woodland development in the Northeastern United states. The emphasis has been on mutualisms (seed dispersal, pollination, and mycorrhizae) and microsite limitations in the recruitment, growth, and reproduction of woody plants. Using plantings of seeds, seedlings, and clusters of reproductively mature plants on abandoned landfills, we have observed that (1) soil microsite deficiencies lead to very poor germination (<0.1$\%$) and seedling survival (<0.01$\%$) of most native species; (2) seed dispersal by birds is a significant and reliable source of woody plant recruitment; however (3) proximity effects are strong, with most (up to 95$\%$) of seed rain falling in the vicinity of planted clusters that are closest to putative seed sources; and (4) remnant natural woodlands are critical components of the recruitment process. To emphasize the last point, in one case, we found that the destruction of approximately 50$\%$ of nearby natural woodland vegetation led to a commensurate decline in seed rain. In another case, we found that the species richness of recruits was strictly limited by the species composition of nearby source plant communities, with no evidence of community enrichment by long distance dispersal over 5 years. We conclude from these results that the size and proximity of remnant natural populations are critical considerations when planning reclamation and restoration programs that rely on natural successional processes.

Purpose: The purpose of this study was to examine the effects of an aging management program on the resilience and successful aging of middle-aged women. Methods: A quasi-experimental study with a non-equivalent control and pre-post test design was used. The participants were 39 middle-aged women living in urban areas in Korea. The experimental group (n=22) received the aging management program for a total of 10 weeks, 90 minutes to 120 minutes per week. The aging management program consisted of strategies to enhance the behavior, promotion conditions, and habits of the program, including various activities for middle-aged women. The data were analyzed using χ² tests, independent t-tests, and repeated measures analysis of variance with the SPSS/WIN 21.0 program. Results: The resilience score of the experimental group was significantly higher level than the score of the control group in the time-to-group interactions (F=3.70, p=0.029). The successful aging score of the experimental group was significantly higher than the score of the control group in the time-to-group interactions (F=5.86, p=0.004). However, the sub-hypotheses of resilience (self-regulation and interpersonal relationships) and successful aging (physical aging adaptation and psychological age adaptation) were partially accepted. Conclusions: The aging management program for middle-aged women was identified as an effective intervention for promoting resilience and successful aging in middle-aged women. Therefore, this suggests that the aging care program could be a useful intervention program to improve the mental health of middle-aged women living in communities.
