  • The three-dimensional structure of an inorganic crystal, $SmZn_{0.67}Sb_2$ (space group $P4/nmm,\;a=4.30(3){\AA}\;and\;c= 10.27(1){\AA}$), was refined by electron crystallography utilizing high voltage electron microscopy (HVEM). Effects of instrumental resolution, image quality, beam damage and specimen tilting on the structure refinement have been evaluated. The instrumental resolution and image quality were the most important factors on the final results in the structure refinement, while the beam damage and specimen tilting effects could be experimentally minimized or controlled. The average phase errors $({\Phi}_{res})$ for the [001], [100] and [110] HVEM images of $SmZn_{0.67}Sb_2$ were $10.1^{\circ},\;9.6^{\circ}\;and\;6.8^{\circ}$, respectively. The atomic coordinates of $SmZn_{0.67}Sb_2$ were consistent within $0.0013{\AA}{\sim}0.0088{\AA}$, compared to the X-ray crystallography data for the same sample.

  • Purpose: The purpose of this study was to investigate the current state and trends of factors influencing the quality of life in low- income elders living at home. Methods: To carry out this study we established the patient, intervention, comparison, outcomes (PICO) strategy, reviewed 241 published documents from both national and international electronic databases, and finally selected 9 references based on inclusion and exclusion criteria alone. The quality of selected references was assessed using 15 questions. Two reviewers independently examined titles and abstracts and assessed whether each met the predefined inclusion and exclusion criteria. Results: The following factors were significantly associated with quality of life in low- income elders: (1) demographic factors such as number of children, income, and age; (2) health - related factors such as joint exercise capacity, activities of daily living/instrumental activities of daily living, health perception, health promotion behavior, and depression; and (3) socio environmental factors such as family support, community-based service program, leisure activity, and the number of neighborhoods involved. Conclusion: The results of our study provide a definite basis for the development of a policy strategy to improve the quality of life in elders with low income and we hence strongly recommend that any strategy to improve the quality of life in low-income elders be based on the results of our study.

  • PURPOSE: This study examined the differences between male and female workers by investigating the various factors that affected the workers' abilities to return to work according to the International Classification of Functioning standards. METHODS: We analyzed the personal factor, environmental factor, work performance and participation factor related to ICF according to worker's gender. For this purpose data from the third Worker's Compensation Insurance panel survey conducted by the Korea Workers' Compensation & Welfare Service were analyzed. In order to verify the research model, we used frequency analysis, cross analysis to compare the differences between male and female workers according to personal, environmental, work performance, and participation factors and hierarchical regression analysis to identify significant factors affecting job performance. RESULTS: The results, indicate that the level of education, license status, working period, socioeconomic status and employment type of female workers were lower than those of male workers. Factors that have the greatest influence on job performance are grade of disability, status of disability, economic activity status, and instrumental activities of daily living (p<.05). CONCLUSION: It is necessary to provide socially stable employment support and social policy support without discrimination to allow disabled female workers to return to work and maintain their jobs and to study factors influencing job performance further.

  • The purpose of this study was 1) to find effects of private Guanxi and organizational relationship on quality of organizational relationship, 2) to find effects of private Guanxi and organizational relationship on performance of distribution channel, and 3) to also find effects of quality of organizational relationship on performance of distribution channel. Apparel manufacturers and distributors in China participated in the study. Random sampling method was used to collect the data. Data from 173 questionnaires were used for the statistical analysis. Factor analysis, Cronbach's alpha coefficient, and regression analysis was conducted. Two factors of private Guanxi were classified(i.e., affective Guanxi, instrumental Guanxi). Three factors of organizational relationship type were identified(i.e., opportunistic relationship, cooperative relationship, vertical relationship). The result indicated that affective Guanxi in terms of private Guanxi positively affected on quality of organizational relationship. Cooperative relationship and vertical relationship in terms of organizational relationship positively affected on quality of organizational relationship. Affective Guanxi positively affected on non-financial performance and financial performance in terms of performance of distribution channel. Instrumental Guanxi in terms of private Guanxi positively affected on financial performance only. Cooperative relationship in terms of organizational relationship positively affected on non-financial performance and vertical relationship positively affected on financial performance. Quality of organizational relationship positively affected on non-financial performance and vertical relationship positively affected on financial performance.

  • 본 연구에서는 기업간 거래 관계의 품질과 강도를 결정함에 있어서 제공조건이 중요한지, 아니면 상대하는 사람이 중요한지 혹은 관계적 특징이 중요한지 여부를 검토하고자 하였다. 이를 위해 주요 선행 특성요인을 제공특성(제공조건), 대인적 특성(상대업체 경영자의 유사성, 전문성), 관계 특성(관계기간, 협력, 의존성)으로 분류하고, 이들 특성이 관계품질과 강도에 어떤 영향을 미치는지를 로칼수출업체-섬유염색나염업체 거래관계 상황에서 실증적으로 분석하였다. 실증분석 결과, 관계기간을 제외한 모든 특성변수는 관계품질 변수(신뢰와 몰입)에 대해 직접적인 영향을 줄 뿐 아니라 관계강도에 대해서도 간접적인 영향을 주고 있음을 확인할 수 있었다. 특히 상대업체 경영자로부터 인식하는 유사성은 관계품질 형성에 강력한 영향을 미치는 것으로 나타났다. 그리고 기업간 의존성은 관계품질이나 관계강도에 대해 유의한 영향을 미치고 있어 기업간 거래에서 자원의존이 중요한 역할을 하고 있음을 확인할 수 있었다. 또한 관계강도에 대해서는 관계품질과 같은 정서적 판단이 유의하게 작용하며, 특히 신뢰변수는 제공특성과 같은 수단적·경제적인 변수에 비해 훨씬 강력한 영향을 미치고 있음을 발견하였다.

  • The aim of this study was to understand the factors related to depression according to gender in vulnerable elderly. We conducted a cross-sectional study with 1,709 elderly beneficiaries of the visiting health care program in Seoul. Depression was measured using the Geriatric Depression Scale Short Form Korea Version(GDSSF-K) questionnaire. Depression score was mild level in vulnerable elderly. There was no gender difference in depression level. Factors related to depression differ by gender. In the elderly men, higher depression showed significant correlation with a lower level of health-related quality of life(HRQOL) and self-rated health(SRH). In addition, higher depression was observed for elderly men living alone than for those living with family. These factors explained depression by 23.1%. In the elderly women, higher depression showed significant correlation with a lower level of HRQOL, SRH and a higher dependence of instrumental activities of daily living. In addition, higher depression was observed for elderly women who has fall experience. These factors explained depression by 22.8%. Gender-specific nursing strategies may be required for prevention of depression in vulnerable elderly.

  • Over the last few years Total Quality Management (TQM) programs have hem widely adapted by Korean manufacturing firms to improve their productivity, competitive edge and product quality levels. The purpose of this study is to evaluate the level of importance placed on four key TQM factors (customer satisfaction, strong management leadership, continuous improvement, imployee involvement and participation) used during the implementation of korean manufacturing TQM programs and to assess the effectiveness of those key factors in improving the performance of the firms. A Questionaire was developed and sent to senior managers in manufacturing organizations throughout korea. This survey asked qustions regarding 1) the firm's business environment and TQM program development 2) subcomponents of the key factors and 3) the effectiveness of the TQM program at improving the performance of the organization. The survey data were analyzed to determine the degree of correlation between each of the factors and the effectiveness of the TQM programs. This study demonstrated that the TQM programs were instrumental at improving the performance of the firms studied, and that the improvement was positively correlated with the length of time that the program had been implemented and the planned duration of the TQM program implementation. It was found that the person-oriented elements of management leadership and employee involvement were positively correlated and predictive of the success of the TQM Program, while the process-oriented components of customer satisfaction and employee involvement were not useful predictors of the effectiveness of the TQM program implementation.
