The purpose of this study is to establish fundamental knowledge on the experience for building resource system using the social networks within the community. This study used a social capital perspective and the grounded theory method based on Strauss and Corbin(1998) and Corbin(2004). Interviews were conducted with 14 Korean social workers (general managers and assistant managers) at community welfare centers who have developed resources by using the social networks or social relations for more than 3 years. In creating autonomy and sustainability of community, there are four types of social worker's efforts in building resource system within the community: 'restoring norms of reciprocity', 'developing citizen's capabilities', 'mobilizing resources through community organizations', and 'utilizing external resource-networks'. These results are contribute to developing theory on social welfare resources using community networks according to characteristics of a community.

Start after striking space key 2 times. Lately, a lot of researches have been done on the resource allocation for multiuser OFDM(Orthogonal Frequency Division Multiplexing) systems due to its spectral efficiency for high-rate multimedia data services. For multimedia services in which every user is guaranteed to have minimum required bit rate and bit error probability, it is critical to utilize the limited resources efficiently to improve the performance of the system. The introduced allocation method improves spectral efficiency to use the left subcarriers in Zhang's algorithm. By using this method, the system can provide services to more users constantly, except for a bit increasing complexity and memory for deciding the left subcarriers and reallocating the subcarriers.

The purpose of this study was to verify the reliability and validity of the Rosenbaum self-control schedule (SCS) for assessing resourcefulness in Korea and to explore the simplified scale. The study subjects consisted of 787 adults in a community. The data was collected during the period from Oct. to Dec., 1995 and analyzed as Cronbach α, item correlation with total, Pearson correlation and factor analysis with varimax rotation using SAS. Results were as follows : The mean SCS score for this sample was 17.2 and there were statistical differences for gender(men, 13.1 ; women, 20.0) on the SCS scores. The cronbachα of SCS with 36 items was .74 and when simplified with 30 items, it's coefficient alpha was .78. The translated content of the SCS was validated by two nursing faculty members and one professor of psychology. Factor analysis revealed the most parsimonious structure was obtained when six factors were extracted and subsequently rotated via the varimax criterion. There was 40.2% of total communality variance in the SCS with 36 items. The total communality variance was slightly increased to 43.4% with 30 items of the SCS. In order to reduce from 36 items to 30 items, the process excepted 6 items having low item correlation with total and low MSA(means of sampling adequacy) of factor analysis. According to factor analysis, there are six factors such as emotion control, impulse control, self-efficacy, coping with problems, pain control and satisfaction control, The SCS was found to have low, but statistically significant, correlations with social desirability and helplessness. From the above results, it can be concluded that the reliability of the SCS(inherent and simplified) was a acceptable level and its validity was reasonable when comparing it with other validity studies. To determine the usefulness the simplified scale, further study is necessary to simultaneously compare and analyze both scales for stability.

The purpose of this study was to investigate the relationship between college women's resourcefulness and health promoting behaviors. The subjects were 215 college women students who were non-married and ranged in grade from 1 to 4. Data was collected from Nov. 1 to Nov. 30, 2001 by a structured questionnaires. The instruments, which were modified by researcher and used for this study, were the revised Health Promotion Lifestyle Profile (HPLP) developed by Walker, Sechrist and Pender(1987), the Resourcefulness developed by Rosenbaum(1980) and the general characteristic scale developed by the researcher. The data were analyzed by the SPSS/PC+ program using t-test, ANOVA, Pearson Correlation Coefficient and stepwise multiple regression. The results were as follows : 1. The mean score of resourcefulness was 109.29(range:$36\sim180$). 2.There were statistically significant difference in the score of resourcefulness according to the grade(F=2.889, P=.037) and drinking(t=-3.264, P=.002). 3.The mean score of health promoting behaviors was 107.21(range: 44~176). 4.There were statistically significant difference in the score of the health promoting behaviors according to the grade(F=.141, P=.039), smoking(t=-3.314, P=.008) and drinking (t=-4.091, P=.000). 5. College women's degree of resourcefulness showed a positive correlation with the degree of health promoting behavior (r=.573, P=.000). 6. By means of multiple regression analysis, the resourcefulness provided explained 32.9% of health promoting behavior. In conclusion, the resourcefulness should be considered when developing nursing strategies for college women, especially when dealing with the health promoting behaviors. The recommendations from this study necessitate of further studies to investigate how smoking and drinking have an effect on the health promoting behaviors.

The purpose of this study was to define the degree of the resourcefulness and the health-promoting behavior of cancer patients, to identify the relationship between the resourcefulness and the health promoting behaviors and to provide the basis for strategic nursing intervention. This study was conducted by an exploratory survey. Data were collected by self-reported questionnaires from 97 cancer patients in a university hospital in Tae-Gu from September to December of 1998. The sample data were collected by using a convenient sampling method. The following instruments were used in the study after some adaptation : Park Chai Soon's Health Promoting Lifestyle Profile, Oh Pok Ja's instrument for health promotion behavior and the Rosenbaum self-control schedule(SCS). The reliability of instruments was tested with Chronbach'alph(.79-.89). Data was analyzed by using the SAS program. T-test, ANOVA, and Pearson's coefficients of correlation. The results of this study were as follows: First, the average score of the resourcefulness variable was 22.20; the range of the score was from -30 to +81 The average score of the performance in the health promoting behavior variable was 96.13; the range of the score was from 39 to 137 Second, the resourcefulness variable was significantly different from such demographic factors as gender and perceived health status, but there was no statistically significant difference between the demographic factors and the health promoting behavior variable, except that of perceived health status. Third, the performance in health promoting behavior of cancer patients was significantly correlated with the resourcefulness of cancer patients(r= .50) In conclusion, resourcefulness was identified to be an important variable that could contribute to promote health-promoting behavior.

The purpose of this study was to identify how internal and external coping resources influenced active coping in the process of stress-coping. The model was established theoretically by comparing and integrating the following theories : Stress-Coping, Self-Care, and Resourcefulness. The subjects consisted of sixty eight patients undergoing chemotherapy(experimental group 34, control group 34) at two general hospitals from January to July, 1995. The results were as follows : After self-care education, the active coping score of the experimental group was significantly higher than that of the control group. The active coping score of the high resourcefulness group was significantly higher than that of the low resourcefulness group. The interaction effect between self-care education and resourcfulness was not significant statistically. Specifically as to such scores of seeking social support, problem-oriented strategy and self care behavior, there were significantly higher in the experimental group and high resourcefulness group than in each of the other groups. Considering them both, self-care education and resourcefulness are effective nursing strategies to promote active coping including self-care. Consequently, the synthesis and testing of theories of stress-coping, self-care, and resourcefulness in this study are mostly proven to enhance the explanation and prediction of the change of active coping including self-care. Therefore the result of this study will contribute in the development of practice theory of nursing. A further study is necessary to reevaluate the interaction effect between self-care education and resourcefulness and to identify the difference between resourcefulness and self-efficacy.
