This study aims at providing more qualitative care in family nursing practice. It is designed to analyze the degree of quality of life(QL) among families of the patients. The subjects consisted of 79 families of hospital hospice patients and 74 families of home-based hospice patients. The ages of the subjects were 17-74 years, at five university hospitals in Seoul, Inchon, and Kyung Gi Province, and one clinic in Chunchon. The data were collected from September, 1996 to August, 1997. The instrument used for the study was the Quality of Life Scale (QLS), which was composed of six factors, developed by Ro, You Ja. The analysis was done using t-test, ANOVA Scheff test, and Stepwise multiple regression. The results were as follows : 1. There were no statistically significant differences between the families of hospital hospice patients and the families of home-based hospice patients ; however, the mean score of the families of hospital hospice patients was higher than that of the families of home-based hospice patients. The scores on QLS ranged from 75 to 224 with a mean score of 140.58 in the families of hospital hospice patients. In the families of home-based hospice patients, the scores ranged from 79 to 214, showing a mean score of 135.25. Among six factors of QLS, family relationships showed the highest score in both groups, but economic life showed the lowest score in the families of hospital hospice patients, and emotional state showed the lowest score in those of home-based hospital patients. Self-esteem and relationship with the neighborhood were significantly higher in the families of hospital hospice patients than the families of home-based hospice patients (t=2.69, P= 0.008 ; 1=2.04, p=0.043). 2. In the families of hospital hospice patients, QL had significant relationship with family member's age(F=2.52, p =0.029), marital status (F=3.57, P=0.018), economic state(F=6.07, P=0.004), and education level(F=3.77, P=0.014). In the families of home-based hospice patients, QL had significant relationship with marital status (F=2.53, P=0.049), education level(F=4.35, P=0.007), occupation(F=3.93, P=0.002), and patient's age(F=2.73, P=0.020) 3. Economic status accounted for 17% of QL, and diagnosis accounted for an additional 7% of QL in the families of hospital hospice patients by means of stepwise multiple regression analysis. In the families of home-based hospice patients, relationships with patient accounted for 12% of QL. The findings showed that self-esteem and relationship with the neighborhood were significantly higher in the families of hospital hospice patients than the families of homed-based hospice patients and family relationships showed the highest value in QL. These findings should be considered in nursing practice.

In this paper, we consider two issues in collaborative filtering, which are closely related with the number of ratings of a user. First issue is the relationship between the number of ratings of a user and the performance of collaborative filtering. The relationship is investigated with two datasets, EachMovie and Movielens datasets. The number of ratings of a user is critical when the number of ratings is small, but after the number is over a certain threshold, its influence on recommendation performance becomes smaller. We also provide an explanation on the relationship between the number of ratings of a user and the performance in terms of neighborhood formations in collaborative filtering. The second issue is how to select an initial product list for new users for gaining user responses. We suggest and analyze 14 selection strategies which include popularity, favorite, clustering, genre, and entropy methods. Popularity methods are adequate for getting higher number of ratings from users, and favorite methods are good for higher average preference ratings of users.

Clustering is an useful method to classify objects into subsets that have some meaning in the context of a particular problem and has been applied in variety of fields, customer relationship management, data mining, pattern recognition, and biotechnology etc. This paper addresses the unknown K clustering problems and presents a new approach based on a coevolutionary algorithm to solve it. Coevolutionary algorithms are known as very efficient tools to solve the integrated optimization problems with high degree of complexity compared to classical ones. The problem considered in this paper can be divided into two sub-problems; finding the number of clusters and classifying the data into these clusters. To apply to coevolutionary algorithm, the framework of algorithm and genetic elements suitable for the sub-problems are proposed. Also, a neighborhood-based evolutionary strategy is employed to maintain the population diversity. To analyze the proposed algorithm, the experiments are performed with various test-bed problems which are grouped into several classes. The experimental results confirm the effectiveness of the proposed algorithm.

본 연구는 영국의 남동잉글랜드지역을 대상으로 사회적으로 박탈된 지역과 학업성취도의 관계를 살펴보고자 하였다. 이 지역은 영국에서 상대적으로 사회경제적 지위가 높은 지역임에도 불구하고 학업성취도의 공간적 편차가 심하게 나타난다. 학업성취도의 공간적 불평등은 거주지역의 박탈여부와 관련하여 설명할 수 있다. 다양한 박탈지표를 사용하여 박탈공간의 패턴을 알아보고 학업성취도와의 관계를 살펴본 결과 남동잉글랜드에서 학업성취도는 사회적으로 박탈된 지역과 매우 밀접한 관련성을 나타냈다. 박탈현상이 심한 지역이 그렇지 않은 지역과 비교하여 상대적으로 낮은 학업성취도를 나타냈다. 남동잉글랜드에서 낮은 학업성취도를 나타내는 박탈지역은 일반적으로 남동해안가에 밀집되어 있으며 내륙으로 들어갈수록 박탈현상이 약해지면서 학업성취도가 높게 나타났다. 그리고 높은 학업성취도에 비해 학업성취도가 낮을수록 거주지역의 박탈요소와 깊은 연관성을 지니는 것으로 설명되었다.

한국 사회의 민주화와 소선거구제로의 변화로 또한 지역기반 정당의 출현으로 13대 총선 이후 전국적인 투표 행태가 종래 여촌야도에서 지역주의적인 양상으로 바뀌었다. 충북 전북 경북의 접경지역인 영동군, 무주군, 김천시를 대상으로 지역적 정당정체성의 변화를 검토하고, 각 후보자 선택 기준의 중요도를 비교하여 투표 행태를 규명해 보고자 하였다. 시군 단위로 볼 때, 타도와의 문화적 친화성으로 인해 영동군은 전면적으로 무주군은 부분적으로 지역당에 대한 지지가 약화되는 반면, 김천시는 지역당에 대한 지지가 확고한 것으로 나타났다. 읍면 단위로 본 이웃효과는 3 시군 모두에서 부분적으로만 확인되었다. 후보자의 정치적, 사회적 특성이 유권자의 투표행위라 할 수 있는 득표율에 어느 정도 영향을 미치는지를 선형근사식을 통해 살펴 본 결과, 여러 설문조사와는 다르게 후보자의 소속 정당이나 출신지역 등 지역적인 선택 기준을 중시하고 있다. 지난 17대 총선을 기점으로 지역정당이 쇠퇴하고 있어 향후 정치적 지역주의에 어떠한 변화가 초래될지 주목된다.

Townhouse have been developed as alternative housing types for combining the characteristics of detached houses and high-rise apartments, Much research on townhouse have investigated physical environments of townhouse and provide a number of planning factors to be considered. However, these factors do not reflect the residents' experiences of the environments sufficiently. The aim of this research is to investigate residents' satisfactions in townhouse as an exploratory study which can be a basis for the improvement of residential environments in townhouse. First of all, we selected a target townhouse and conducted a field study to examine the existing state of the townhouse. Then a customized questionnaire was developed and distributed to residents in the townhouse for investigating their satisfactions on the residential environment. The questions included are divided into four categories; site environment, unit space, community area and housing management. Through the statistic analyses of the residents' responses, the residents' satisfactions of the residential environment were identified. Especially the residents' satisfaction on the community area, which revitalizes neighborhood relationships, is very high. They were also satisfied with the conditions of the sub-categories, 'a distinctive exterior' 'a private planning', 'outdoors' and 'landscapes', in townhouse. In conclusion, we suggested considerations for the improvement of the residential environments and the quality of life in townhouse.

본 연구는 도시지역의 사회구조적 특성이 범죄에 미치는 영향을 생태학적 범죄이론에 근거하여 검증하고자 했다. 이를 위해 서울시의 424개 행정동을 대상으로 살인범죄에 대한 음이항 회귀분석을 실시했다. 그 결과, 기초수급자비율이 높을수록, 세대당인구수가 적을수록, 숙박 음식업비율이 높을수록 살인범죄가 증가하는 것으로 드러났다. 이는 온전한 가족의 중요성을 다시 한 번 증명해보임과 동시에, 도시지역에서는 숙박 음식업비율과 기초수급자비율이 범죄유발요인으로 작용할 수 있음을 보여준 결과였다. 과거의 시군구 대상 연구들과 더불어 유추하면 지역 특성에 맞는 맞춤형 범죄예방책이 필요함을 알 수 있었다. 살인범죄에 국한되고 횡단적 연구설계가 이루어지는 등의 몇 가지 한계점들이 있었지만, 서울시의 전체 행정동을 분석단위로 한 최초의 범죄연구로서 향후 동 단위 연구의 활성화와 효과적인 범죄예방책 마련에 기여한 의미가 있다.

In contemporary Korean society, urban community environment is often associated with high-density and high-rise residences that make people's relationships superficial, instrumental and impersonal. Furthermore, urban community consistently interplays with neighboring residents and childhood emotional experience are influential on their unconscious images and attitude about their current neighborhood environment, while affecting the environmental attitude and the formation of community sense. Previous research found evidences that increased level of community sense is fostering more feeling of living in so-called "real neighborhood environment." This study aimed to cross-culturally examine what the respondents' emotional perception and their attitude were about the community environment in their childhood through environmental autobiography method and to examine the effects of the results on adults' formation of sense of community for their current community environment. Extensive literature review explored a few important theoretical framework which are closely related to sense of community (SOC) as a result of emotional experience: membership, influence, integration and fulfillment of needs, shared emotional connection and community satisfaction. Chi-square and GLM analysis revealed that there were no demographic, and socio-economic differences between two groups of Korean and US residents. Correlation analysis indicated that childhood emotional experience of Koreans and US citizens was statistically significant on sense of community for their current living community. Multi-regression analysis also found that the degree of influence were the main predictors for building strong sense of current community throughout a cross-cultural group. Furthermore, the relationship between various emotional experience of each factor in previous and current community environment were statistically significantly related. It is concluded that as the positive childhood experience of influence in their past community was going up, the level of sense of community for their current community was strengthened across their cross-cultural background.
