  • Since the scale of vessels is growing up recently, some troubles between the shaft and after bush bearing are frequently reported. Generally, mean pressure on bush bearing is used as a design criterion. However, in some case of the long bearing such as after bush bearing of the propulsion shaft, it might be liable to be locally under high pressure. As for the main engine bearings and the intermediate shaft bearing, it is reasonable to take the mean pressure as a design criterion. But, in case of after bush bearing, it is not sufficient because of the possibility of high pressure caused by local contact. In this study, Hertzian contact condition was applied to evaluation of the local pressure for after bush bearing. To reduce the local maximum pressure, the height of the after bush bearing was controlled. It was found that local maximum pressure could be reduced effectively by taking a partial slope on the white metal of the aft bush bearing.

  • Surgery is a very hands-on area of medical care, in that surgeons identify problems in patients' bodies and directly change them through operations. Therefore, it is not only necessary for surgeons to have a high level of expertise, but also to take considerable responsibility for the outcomes of each operation. However, surgery, which was once an object of envy, has long been a process to avoid, due to various circumstances, such as abnormal medical expenses in the medical field and social phenomena that avoids difficult work. It is unfortunate that medical professionals do not receive sympathy from others within the same medical field because of the general difficulties of the profession. The fundamental problem in this situation is the abnormal profit structure of the Korean medical system. Efforts by various related organizations will be needed to objectively evaluate the problems of the current medical insurance system and to make reasonable adjustments considering the difficulty, frequency, and resource-intensiveness of medical care.

  • It has been the paradigm of game theory that more than two utilities compete and determine the price and amount of dispatch. In order for this theory to be available on real power system, it is necessary to consider the transmission costs as well as the generation costs. In addition Independent System Operator(ISO) should be able to mitigate the congestion, recover the transmission costs and provide information for long-term capacity investment by devising reasonable pricing schemes for the transmission services. Generators also have to take the transmission costs into account when building the bidding strategies. This paper proposes an approach to analyzing the profit maximizing game considering the transmission cost in a competitive electricity market.

  • Dr. Corley had various experiences as an outstanding structural engineer. His experience as the chief investigator for the collapse of World Trade Center and Oklahoma city building was so much useful to the lecture. His presentation had covered 3 different collapsed buildings like Oklahoma city, Pentagon and World Trade Center. He had shown to the audiences 2 videos and 76 slides by power point. The learned lessons from his presentation were: 1. The appropriate Building Code is very important. 2. The sound details are very important for the structure to resist the extreme outer force. 3. The continuous diagnosis and maintenance of the structure is important. 4. The reasonable attitude of the government against the accident is important. 5. The professional engineer must take a main role as a guard for the safety of the people.

  • A survey was conducted to get information on the utilization of irrigation systems for greenhoyses farming. Three regions were selected which represent geographical chatacteristics such as neighboring urban area, flat-field area, and mountainous area. The number of greenhouses farms interviewed was 432 in total. The contents of the survey consisted of general characteristics of greenhouse farmers, the size and location of greenhouses, cultuvated crops, irrigation method, irrigation scheduling, and irrigation automation. The analysis of the surveyed data showed that greenhouse farmers did not take technical assistances. Proper criteria or guidelines for selection and operation of irrigation systems were not available. Irrigation systems were operated by hand. Irrigation scheduling were executed by farmer's experience. Maintenance of irrigation systems in general were poor. Development of economically reasonable irrigation system is of importance.

  • It is rare that the dwelling buildings designated as cultural assets owing to the demands of the rapid-changing times and their residences are conserved as their original shapes, though the extent varies. Meanwhile, there has been a continuous effort to preserve and take over our traditional dwelling culture. Yet, the effects were not tangible because the viewpoints are different between the conservation promoters and related residents-officials-experts and because the conservation method is not decided in advance. Thus, in conserving the traditional dwelling culture containing the history of human life, this study tries to find out the reasonable ways for conserving traditional residence based on the consciousness research of citizens on conserving and utilizing the cultural assets. Furthermore this study also tries to suggest to contemporaries - who should live side by side with the historic cultural assets - what attitude they should have. On the basis of above survey, the objective of this study is said to consist in presenting the directions - what efforts are needed - for the more active and participant conservation.

  • Automatic license plate recognition (LPR) is one of the critical techniques of the intelligent transportation system (ITS), in which license plate location plays an important role. In this paper, through surveying the international existing techniques, a new method for locating license plate is proposed: utilize row scan method to locate up and down boundary of the plate; and based on the location of up and down boundary, take advantage of the feature of plate area to locate left and right boundary of the plate. The tests of using the proposed algorithms have been conducted. The experimental results show that the proposed approaches are reasonable and accurate.

An Arbitrator's Duty of Disclosure and Reasonable Investigation: A Case Comment on the Supreme Court of Japan's Decision on December 12, 2017, 2016 (Kyo) 43 (중재인의 고지의무와 합리적 조사의무 - 일본 최고재판소 2017년 12월 12일 결정을 중심으로 -)

  • This paper reviews the Supreme Court of Japan in Decision of December 12, 2017, 2016 (Kyo) 43 (2011) concerning arbitrator's duty of disclosure and reasonable investigation under the Japan Arbitration Act (Arbitration Act). The Supreme Court of Japan recently issued a precedential decision interpreting, for the first time, the arbitrator disclosure requirements of the Arbitration Act. Under Article 18(4) of the Arbitration Act, arbitrators have an ongoing obligation to disclose circumstances which may give rise to justifiable doubts as to their impartiality or independence. The Supreme Court held that Article 18(4) of the Arbitration Act - requiring arbitrators to disclose all "facts likely to give rise to doubts as to his/her impartiality or independence" - (1) is not satisfied by blanket disclosures or advance waivers of potential future conflicts, and (2) requires disclosure of facts both known to an arbitrator or "that can be normally ascertained by an investigation that is reasonably possible${\cdots}$" This new standard presents opportunities and challenges for enforcing arbitration awards in Japan, and suggests measures that both arbitrators and parties can use to protect their awards. Also, the Supreme Court's new standards for evaluating arbitrator conflict disclosures suggest some measures that both arbitrators and parties to arbitration in Japan can take to protect the enforceability of their awards. The key factual question posed by the Supreme Court's ruling was whether an arbitrator's conflicts check was reasonable. Maintaining records regarding a review of potential conflicts or any investigation provides a ready source of proof in case of a future challenge. The Supreme Court has spoken clearly that so-called advance waivers of potential conflicts are not effective under Japanese law. Instead, to the extent that potential conflicts arise during the course of arbitration, they should be specifically disclosed.
