In this paper, the vibration diagnosis system of a rotating machinery is introduced, in which the vibration signals of multiple accelerometers and displacement sensors are used combinedly as input parameters and their characteristics of the vibration response and mutual relationships between each sensor signal are considered to improve the reliability of the diagnosis system. The fuzzy logic is utilized for inferencing the fault from the vibration signal patterns.

Pythagorean thoerem exists in several equivalent forms in the Euclidean plane, that is, the Hilbert plane which in addition satisfies the parallel axiom. In this article, we investigate the truthness and mutual relationships of those propositions in various non-Hilbert planes which satisfy the parallel axiom and all the Hilbert axioms except the SAS axiom.

The goal of this study is to develop a program which can improve couples' communication skills that serve to enhance their relationships and to evaluate the effectiveness of the program. The summary of major result of the research were as follows; 1 The content of communication program for couples in the early marriage focused on improvement of communication skills, on enhancement of couples' intimacy and on coping ability for marriage life. 2. The developed program served to communication improvement for couples in the early marriage. Analyzing specifically the results of test before and after, the average scores of sub-areas such as listening, speaking and solving problems were all increased after the program than before the program. Significant differences of sub-areas appeared, either. 3. The developed program contributed to enhancement of couples' mutual understanding and their relationships.

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.

본 연구에서는 자유선택활동 시간에 일어나는 만4세반 유아의 다양한 모습을 관찰하고 분석해 봄으로써 또래문화의 특성을 이해하고 유아의 내면에 한걸음 더 다가갈 수 있는 장을 마련해 보고자 하였다. 이를 위해 서울에 위치한 S 어린이집 만4세 하늘반의 자유선택활동을 참여관찰하고 교사와 유아와의 면담을 통해 질적연구를 실시하였다. 연구 결과, 상호 존중하는 또래관계와 순응하는 또래관계를 통해 형성되는 '평화적 또래문화,' 그리고 수직적 또래관계, 배타적 또래관계, 무시형 또래관계를 통해 형성되는 '갈등적 또래문화'가 나타났다. 본 연구에서는 유아들의 관계형성 분석을 통해 만4세 유아의 또래문화를 밝혀 봄으로써 유아의 내면세계를 이해하고 유아의 교실문화를 폭넓게 바라 볼 수 있는 기초자료를 제공했다는 것에 의의가 있다.

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.

SCM은 기업의 성과를 향상시키기 위해 공급사슬 전체를 유기적으로 통합한 전략적 협업체이다. SCM의 활동을 효율적으로 달성하기 위해서는 상호 장기적 관계수립을 위한 변화관리가 강조되고 있다. SCM 시스템의 구현은 공급사슬 내의 기업 및 구성원들의 광범위한 변화를 가져오고, 이러한 변화는 기업 및 구성원의 저항에 부딪칠 수 있기 때문이다. 따라서, 효과적인 변화관리 없이는 SCM 시스템의 성공을 보장 할 수 없다. 또한 본 연구에서는 정보특성 (정보품질, 정보공유)를 통한 SCM 시스템성과를 측정하기 위해 정보역량을 개념을 채택하였다. 따라서, 본 연구는 변화관리가 정보품질과 정보공유를 통해 정보역량에 미치는 상호호혜적인 인과관계를 밝히고자 하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 변화관리는 정보품질, 정보공유, 정보역량에 모두 유의한 영향을 보였다. 둘째, 정보품질 역시 정보공유 및 정보역량에 유의한 영향을 보였다. 마지막으로, 정보공유 또한 정보역량에 유의한 영향을 보였다.
