  • Many types of disasters are related to environmental problems. Today, frequently occurring disasters and global environmental problems have begun to threaten human life and welfare. Consequently, building sustainable communities requires assessing relationships between environmental problems and disasters using a broad, open approach and with a long-term perspective. This paper attempts to identify the need for conceptualizing disasters and environmental problems together by comparing mechanisms of both disasters and environmental problems, and attempts to integrate both of these seemingly different types of phenomena as similar types of risk threatening human existence. Based on this work, a chart is proposed for qualitatively organizing disasters, environmental problems and their mutual influences, as well as providing a framework for potential quantitative analysis. It is hoped this research serves to contribute to effective mitigation to both disasters and environmental problems in today's age of global environmental issues.

  • This study aimed to examine factors and the correlations of burnout and job satisfaction in hospital dietitians. Burnout was classified into three sub-concepts: emotional exhaustion, depersonalization, and reduced personal accomplishment. Job satisfaction was also classified into three sub-concepts, including relationships, self-realization, and advancement opportunities. A survey was conducted with dietitians working in general hospitals of over 400 beds, in the Seoul metropolitan area. The factors that significantly influenced emotional exhaustion were health, work hours, number of intern dietitians, self-esteem, level of responsibility, while the factors that influenced depersonalization were relationships with coworkers, and role ambiguity. Personal accomplishment was influenced by age, the number of staff dietitians, the general number of managed workers, and self-esteem. In terms of job satisfaction, relationship was affected by age and relationships with supervisors, while self-realization was influenced by work hours, health, the number of patient meals, and role ambiguity. Age, job regularity, business management, role ambiguity, and relationships with supervisors also affected advancement opportunities. Emotional exhaustion, depersonalization, and reduced personal accomplishments, which represented burnout, had negative relationships with satisfaction with relationships, self-realization and advancement opportunities. Dietitians with low job satisfaction were likely to experience burnout. These results suggest that burnout and job satisfaction are influenced by internal and external factors that are individual or organizational problems encountered by hospital dietitians. Therefore, managers as well as dietitians need to understand these factors and overcome them through communication and mutual support.

  • This study attempts to understand perceived switching barriers of customers and fashion stores service quality as a core of store loyalty. Medium variations of switching barriers are interpersonal relationships, attractiveness of alternatives and switching costs. Date were collected from 485 subjects who finished their shopping with a self-administered questionnaire. The results were as follows: 1. Classified service quality of clothing stores into 4 ways: VMD of stores or atmosphere, store policy which are involved in store service, sales persons respond and sales persons conviction which are involved in sales service. 2. Service quality of fashion stores is related with switching barrier medium variations. 3. Service quality have an influence on switching barrier medium variations. Its mutual influences increase switching barriers and it gets to be related to the store loyalty. 4. Compared influences of variations to store loyalty between the H department store and the L department store which are research objects. The main difference is that the H department store evaluated personal relationships among service quality, customers and sales persons high compared with the L department store. As the results showed, service quality consists of store service of nonpersonal service area and sales service of personal service. Service quality is related with interpersonal relationships, attractiveness of alternatives and switching costs. It also affects switching barriers and store loyalty.

  • Gyeongsang Basin in the southeastern part of the Korean peninsular is characterized by many fault systems. To decipher the geotectonical evolution of the Korean peninsular and marginal basins in her adjacent areas it is prerequisite to understand the spatial distribution pattern and mutual relationships of these fault systems. Because of difficulties in finding any criterion to recognize the faults in field, their extension and mutual relationships in ages are not very clear yet. As an attempt to find geophysical criteria to recognize the fault, geoelectrical resistivity survey was carried out in this study. With the Wenner configuration four resistivity soundings and twenty seven resistivity profilings were done. The electrode distance used was up to 50m. From the results of the resistivity soundings and boring data of earlier groundwater investigations the depth of alluvial and weathered zone was established to be at most 20m in the study area. In the resistivity profiling low resistivity anomaly zones are detected on every traverse, which are interpreted as caused by fractures, fault clays and mylonites in the fault zone. The width of the fault zone amounts to 0.3-1km. By correlating and connecting the negative anomaly zones from traverse to traverse one can determine the trend of th of the faultzone and therefore that of fault itself. The recognized fault trend in this way was $N15^{\circ}-20^{\circ}E$ and this coincides with the direction of the inferred fault line from earlier geological surface mapping. With the help of this characteristical negative anomaly the existance of another $N80^{\circ}W$ trending fault was estabished. This study has shown that geoelectrical resistivity survey can be applied successfully to the problem of tracing fault line insofar as a fault zone has been developed along fault line.
