For the purpose of monitoring by ultrasonic test of the ball bearing conditions in rotating machinery, a system for their diagnosis was developed. ultrasonic technique is used to detect abnormal conditions in the bearing system. And various data such as frequency spectrum, energy and amplitude of ultrasonic signals, and ultrasonic parameters were acquired during experiments with the simulated ball bearing system. Based on the above results and practical application for power plant, algorithms and judgement criteria for diagnosis system was established. Bearing diagnosis system is composed of four parts as follows : sensing part for ultrasonic sensor and preamplifier, signal processing part for measuring frequency spectrum, energy and amplitude, interface part for connecting ultrasonic signal to PC using A/D converter, graphic display and software part for display of bearing condition and for managing of diagnosis program.

Korea Shipping Act admits shipping conferences' joint actions like rate agreement, sailing agreement in some degree for development of shipping transport industries for decades. Meanwhile, EU has prohibited all kinds of shipping conferences' joint actions since October 2008, and many advanced countries also have similar position on shipping conference. The balance development between shippers and ship owners is very important in terms of national economic growth. So it is appropriate time to revise related laws such as Shipping Act and Monopoly Regulation and Fair Trade Act. First, It is direction for revision of Korean Shipping Act. The act has to define precisely the criteria of "unfairness" in case of admitting of shipping conferences' joint actions. Shipping conferences have a conference with shipper or shipper's delegation substantially on freight and transport conditions and so on. Second, It is direction for revision of Monopoly Regulation and Fair Trade Act. The fair trade commission has to perform fair roles between shippers and ship owners. The judgement of fairness has to confirm according to the spirit of not Korea Shipping Act but Korea Monopoly Regulation and Fair Trade Act itself.

Objectives: The purpose of this study was to examine the correlation between oral malodor and related factors in visitors to preventive dentistry practice lab. Methods: The subjects were selected from 71 visitors to preventive dentistry practice lab in a department of dental hygiene. The subjects were from twenty to twenty nine years old and had no systemic diseases or symptoms. The questionnaire consisted of general characteristics, oral malodor concentration, oral health status, oral health behavior, and self-rated oral malodor. Results: The mean concentration of the oral cavity gas was 50.80. The score of 50.80 was a weak smell by the selected judgement criteria. The oral malodor prevalence rate accounted for 39.1 percent and a weak smell was detected in 40 points. Those having higher oral malodor concentration tended to have lower self-rated oral health status(p<0.05). Conclusions: The results can not be generalized to determine the cause of oral malodor, but self-rated oral health status can be linked to systemic disease control. More investigation should be taken in order to analyzed the correlation between oral malodor and systemic diseases.

The relaxation of the regulation in selection of medical institution allows patients to use their own judgement in choosing proper institution for their diseases. Since the change of the regulation, there should have been many changes in medical institution selection behavior. The analysis of the change in disease specific selection pattern is critical because there be an optimal selection criteria that ensure the efficient and effective utilization of medical resources. This study analysis the institution selection factors by comparing the choice among the cases of acute diseases, the cases of chronic diseases, inpatient services, outpatient services, and emergency medical service. The comparisons performed in terms of size, class and other characteristics of medical institutions. For the study the nationally surveyed database was used and the data were analyzed using logistic regression procedure. The results indicates that the primary care facilities were not properly utilized. This study speculates that the reason for the undesirable pattern of utilization is that the roles of primary care facilities in the healthcare delivery system was not clearly defined. Based on the results, the medical policy implications are discussed.

문화는 그 사회를 구성하는 구성원의 행동과 판단의 준거가 되기 때문에 전략적 제휴에도 많은 영향을 미친다. 정기선사간의 전략적 제휴의 실패는 재무적인 요인이나 영업적인 요인들보다도 문화적인 요인의 영향을 더 많이 받는다. 문화적인 요인에 영향에 의한 전략적 제휴의 실패는 파트너에 대한 문화적인 차이를 간과한 결과이므로 다른 요인들보다도 문화적인 요인에 대한 우선적으로 고려해야 한다. 문화에 대한 개방성을 통해 파트너를 이해하고, 전략적 제휴를 수행하는 구성원들의 만족을 고려해야 전략적 제휴를 성공적으로 이끌 수 있다.

The purposes of this study were to find the difference of clothing life-style and to examine clothing buying behaviors on personality types. Personality types were identified using Myers-Briggs Type indicator(MBTI). The data were collected from 360 female adults using a questionnaire to clothing lifestyle and clothing buying behavior. The data were analysed with factor analysis, one- way ANOVA and Duncan＇s multiple range test. Results are summarized as follows: First, ＇Fashion-oriented＇, ＇self-regulate-oriented＇, ＇activity-oriented＇, ＇economic-oriented＇, ＇social-oriented＇, ＇leisure-oriented＇ and ＇conservationoriented＇ clothing life-style had a significant difference of psychological types. Second, Extroverted(E) or Sensation(S) or Feeling(F) types regarded significantly higher in ＇VMD＇, ＇store atmosphere＇, ＇famous brand name and store name＇ as criteria for store selection than combination types(IN, IT, NT) of Introverted(Ⅰ), iNtuition(N), Thinking(T). Third, Sensation Judgement types(SJs) of a patron temperament preferred a ＇plan-oriented＇ life-style and considered ＇famous brand name and store name＇ important. Sensation Perceiving types(SPs) of an artist temperament had an ＇unplanned＇ clothing life-style and a significantly higher impulsive buying orientation than SJs.

Recently, applications of integrated large composite structures have been attempted to many structures of vehicles. To improve the cost performance and reliability of the integrated composite structures, it is necessary to judge structural integrity of the composite structures. For the judgement, we need fracture simulation techniques for composite structures. Many researches oil the fracture simulation method using FEM have been reported by now. Most of the researches carried out simulations considering only matrix cracking and fiber breaking as fracture modes, and did not consider delamination. Several papers have reported the delamination simulation, but all these reports require three-dimensional elements or quasi three- dimensional elements for FEM analysis. Among fracture mechanisms of composite laminates, delamination is the most important factor because it causes stiffness degradation in composite structures. It is known that onset and propagation of delamination are dominated by the strain energy release rate and interfacial moment. In this study, laminated composite has been described by using 3 dimensional finite elements. Then impact behavior of the laminated composite is simulated using FEM(ABAQUS/Explicit) with progressive failure mechanism. These results are compared with experimental results.

본 연구는 신용장 서류심사의 일치성 판단기준에 대해 우리나라 대법원의 실무적 판례를 중심으로 고찰하고자 한다. 대법원의 서류심사의 일치성 판단기준은 엄격일치의 원칙이 지지되고 있다. 그리고 대법원이 서류심사에서 그 판단이 구체적인 경우는 신용장과의 차이가 국제적 표준은행관행에 비추어 용인될 수 있는가의 여부를 따른다. 이 경우 대법원은 국제표준은행관행으로 국제상업회의소(ICC)의견이나 결정을 참고하기도 하고, ICC의 의견이나 결정이 없는 경우는 국제표준은행관행을 탐구하여 인정하기도 할 것이다. 그러나 은행 서류심사자들이 서류심사를 할 경우 고도의 높은 식견과 지식이 없으므로 짧은 시간에 이를 찾아 판단하는 것이 지극히 어려운 일이 될 것이다. 본 연구의 사례에서 보듯이 신용장의 엄격일치의 원칙은 계속 완화되어 가고, 최근의 판례는 거의 대부분 엄격일치의 예외로 판시하고 있다. 그러므로 은행 서류심사자들은 이와 같은 일치성판단이 어렵기 때문에 자의적 서류심사행위를 하는 것이 불가피하게 될 것이다. 그 결과 은행과 개설의뢰인은 서류상의 엄격성을 확보하는 것이 어렵게 되고, 국제거래에서 신용장의 자유로운 사용을 기피하게 될 것이다. 따라서 은행실무자의 신용장 서류심사의 일치성 판단기준에 대한 다양한 실무적 적용에 본 연구가 활용되기를 기대한다.
