Purpose: This paper was attempted to focused on the analysis of job stress and job satisfaction according to the moderating effects of social support. Method: Data collected from 302 staff nurses in 2 general hospitals, with self-reporting questionnaires(Wolfgang's HPSI, modified Hagihara's social support, and MSQ). Descriptive statistics, Cronbach's alpha, Pearson correlation, ANOVA, and moderated regression analysis were used. Result: The subjects exhibited significantly highest level of 'the work and patients' conditions'. The perceived job stress was negatively correlated with supervisor and co-workers' support, and job satisfactions. Also supervisor and coworkers' support were positively correlated with job satisfactions. The main factor that affected the job satisfactions was 'work and patient conditions' and it was explained 35.5% out of the total variance of the job satisfactions with 'the work load and disturbing factor', 'supervisor support' and 'co-workers' support'. Supervisor support moderated the relationships between 'the patient care responsibilities and career development factor' and satisfaction. Conclusion: For developing the stress management program for hospital nurses, 'the work and patients' conditions', and the strategies of strengthening 'supervisor and co-workers' support' should be considered. In addition to, it may be considered to examine the effects of social support on the other criterion variables.

감성에 대한 기존 연구들은 감성 요인들을 추출하는 데에 치중하여 왔으며, 감성의 내적 구조에 큰 관심을 보이지 않았다. 본 연구는 감성에 감각적 측면과 정서적 측면이 있으며, 이들이 대상의 속성을 묘사하는 객관형용사와 경험자의 심리를 묘사는 주관형용사에 각각 상응한다고 보았다. 국어학적 분류와 경험적 평정을 통해 최종 선별된 43 개의 객관형용사 군과 21 개의 주관형용사 군에 대해 요인분석을 하여, 감각적 측면(객관형용사)의 다섯 요인과 정서적 측면(주관형용사)의 세 요인을 추출하였다. 두 측면의 요인점수들에 대한 다중회귀분석을 통해, 감각적 측면과 정서적 측면 간의 위계 구조를 도출하였다. 그 결과 감성의 정서적 측면은 여러 감각적 요인의 결합으로 파악될 수 있었다. 본 연구의 제한점과 의의를 논의하였다.

The purpose of this study was to develop a "Korean Childcare Teacher's Job Satisfaction Scale"(KCTJSS) and to evaluate its reliability and validity. KCTJSS was 72 items and 6 point Likert scale. Participants consisted of 211 childcare teachers by purposive sampling. Results were as follows: First, Exploratory factor analysis resulted in 40 items composed of 6 factors : The principal's childcare center operation system, working environments and welfare, social recognition, amount of work and time management, relationships with co-workers, relationships with parents. Second, the confirmatory factor analysis supported a 6 factor structure. Third, Criterion-related validity was confirmed by significant correlations of the present scale with Early Childhood Job Satisfaction Survey(Jorde-Bloom, 1989). Fourth, the reliability of factors using Cronbach's ${\alpha}$ appeared high, ranging from .83 to .93.

In this study, we propose a three-dimensional simplified slope stability analysis using a hybrid-type penalty method (HPM). In this method, a solid element obtained by the HPM is applied to a column that divides the slope into a lattice. Therefore, it can obtain a safety factor in the same way as simplified methods on the slip surface. Furthermore, it can obtain results (displacement and strain) that cannot be obtained by conventional limit equilibrium methods such as the Hovland method. The continuity condition of displacement between adjacent columns and between elements for each depth is considered to incorporate a penalty function and the relative displacement. For a slip surface between the bottom surface and the boundary condition to express the slip of slope, we introduce a penalty function based on the Mohr-Coulomb failure criterion. To compute the state of the slip surface, an r-min method is used in the load incremental method. Using the result of the simple three-dimensional slope stability analysis, we obtain a safety factor that is the same as the conventional method. Furthermore, the movement of the slope was calculated quantitatively and qualitatively because the displacement and strain of each element are obtained.

The objective of this study is to examine fracture characteristics of concrete at early ages, i.g. critical stress intensity factor, critical crack-tip opening displacement, fracture energy, and bilinear softening curve based on the concepts of effective-elastic crack model and cohesive crack model. A wedge splitting test for Mode I was performed on cubic wedge specimens with a notch at the edge. By experimenting with various strengths and ages, load-crack mouth opening curves were obtained, and the results were analyzed by linear elastic fracture mechanics and FEM(finite element method). The results from the test and analysis showed that critical stress intensity factor and facture energy increased while critical crack-tip opening displacement decreased with concrete aging from 1 day to 28 days. Four parameters of bilinear softening curve from 1 day to 28 days were obtained from a numerical analysis. The obtained fracture parameters and bilinear softening curves at early ages from this study are to be used as a fracture criterion and an input data for the finite element analysis of concrete at early ages.

Purpose: To develop and test the validity and reliability of the Korean version of outcome expectations-2 for exercise. Methods: The Korean version of outcome expectations for exercise-2 was developed through forward-backward translation techniques. Content, criterion, and construct validity using confirmatory factor analysis and an internal consistency reliability were conducted. Survey data were collected from 200 older adults living in a community. Results: The Korean version of outcome expectations for exercise-2 had factor loadings of the 13 items ranged from .20 to .76, and was validated by confirmatory factor analysis (CFI=.829, NFI=.754, RMSEA=.086). Also there was a reliable internal consistency with a Cronbach's ${\alpha}$ for the positive domain of outcome expectations for exercise scale-2 of .73. Negative domain, however, reported slightly low Cronbach's ${\alpha}$ of .63. Conclusion: The findings of this study demonstrated that the Korean version of outcome expectations for exercise-2 had satisfactory validity to measure expectations regarding exercise among older adults in Korea. Negative domain, however, should be retested to verify reliability for the further study.

The purpose of this study was to develop a checklist of risk factors for quantitative assessment of musculoskeletal complaints in shipbuilding workers. A key point was to develop comprehensive a checklist including the worker's physical ability, as ergonomic and workload factors. ln the first, through correlation analysis between musculoskeletal complaints and physical abilities in shipbuilding workers, risk factors related to physical abilities were selected. In the second, after the development of a checklist was composed of physical, ergonomic and workload factors, factor analysis was used to test the validity of the developed checklist. Each factors selected finally showed that physical factors were hand grip strength, spinal curvature, and flexibility (sit to reach), ergonomic factors were posture, total exposed time, duration, and force of working, and workload factors were physical and psychological workload perceived by worker. The results showed that musculoskeletal complaints was associated with physical abilities (p<.05). The developed checklist had a reliability of .761 (Cronbach=.761) and a validity and explanation of 54.9%. The criterion of management was classified in 4 stages by relative weights of each factor. It is suggested that active intervention is needed to reduce musculoskeletal complaints in workers with more than a 14.31 score.

Purpose: The purpose of this study was to develop a scale to assess the transition shock experienced by newly graduated nurses, and test the validity and reliability of the scale. Methods: The initial items were identified through a review of literature and in-depth interviews with nine newly graduated nurses. Content validation of the items was evaluated by five nurse professors and three nurses. Participants were 269 newly graduated nurses who worked at six acute care hospitals in Busan, Ulsan, and Yangsan, South Korea. Data were analyzed using item analysis, exploratory and confirmatory factor analysis, criterion related validity, and internal consistency. Results: The final scale consisted of 18 items and six factors (conflict between theory and practice, overwhelming workload, loss of social support, shrinking relationship with co-workers, confusion in professional nursing values, and incongruity in work and personal life), which explained 71.3% of the total variance. The six subscale model was validated by confirmatory factor analysis. Cronbach's alpha for the total items was. 89. Convergent validity was evaluated by analyzing total correlation with burnout (r=.71, p<.001) and turnover intention (t=5.84, p<.001). Conclusion: This scale can be used in the development of nursing interventions to reduce the transition shock experienced by newly graduated nurses.

Purpose: The purpose of this study was to develop a new version of Spirituality Assessment Scale (N-SAS) and verify its reliability and validity. Methods: The total of 59 preliminary items for the N-SAS were selected through a literature review, two rounds of experts' content validation, cognitive interviews, and pre-tests. Verification of its reliability and validity was divided into two phases. In Phase I, questionnaires were collected from 219 adults. Reliability was tested using Cronbach's alpha, validity with item analysis, and exploratory factor analysis. In Phase II, questionnaires developed based on the results of Phase I were collected from 225 adults. Reliability was tested using Cronbach's alpha, validity with confirmatory factor analysis, and criterion validity. Results: The final version of the N-SAS comprised two dimensions (vertical and horizontal), four domains (relationship with God; meaning of life and self-integration; self-transcendence; and relationship with others, neighborhoods, and nature), and 44 items were identified. Total Cronbach's α was .97; those of each subscale ranged from .79 to .98. N-SAS scores were positively correlated with the scores of Howden's Spiritual Assessment Scale (r=.81, p<.001). Conclusion: Findings suggest that the N-SAS can be used to measure spirituality in adults. The use of N-SAS is expected to facilitate perceiving patient's spiritual needs and providing spiritual care.

Biobank Impact Factor (BIF), which is a very effective criterion to evaluate the activity of biobanks, can be estimated by the citation information of biobanks from scientific papers. We have developed a program, ManBIF, to investigate the citation information from PDF files in the literature. The program manages a dictionary for expressions to represent biobanks and their resources, mines the citation information by converting PDF files to text files and searching with a dictionary, and produces a statistical report file. It can be used as an important tool by biobanks.
