In this paper, we consider the train-fleet assignment problem to determine fleet assignment and seat allocation synchronously. An integer programming model of the problem and a decomposition-based solution approach are developed to handle short-term period deterministic orgin-destination demands. The primary objective used in the developed model is to maximize the total number of passengers transported during peak load periods, such as Chuseok national holiday period. Thus, in developing the model we choose to profit-pursuing system. We also show how the proposed model can be readily modified to incorporate profit-maximization. Using the empirical data sets provided by a Korean railroad company, we have tested the proposed solution approach and carried out various comparison analyses by varying traffic demand patterns and train schedules. The computational experiments reveal that the proposed solutions approach produces high quality solutions in reasonable computation time.

Today the design is recognized as indispensible part in business activities and it is demanded as one of the management strategies. since the ultimate goal of a hotel lines in the pursuit of profit, it is important that the design of a hotel faithfuly reflects the demands of management at the time of its construction planning. Furthermore, hotel planning undergoes a complicated design phases on a large scale, thus, utilization of a design process that accomodates retional approaches scientific and structural design activities, which will further reduce errors in design steps and pave a way for effective attainment of the target. Especially the management and designers review and confirm the design in relation to the strategic manegiable objective sat the early basic stage. The baseline set here will serve as a direction for the detailed design. In this context, this thesis formulates a reference baseline in dividing the space in view of the overall profitability and is based upon a survey conducted on the correlation between the operation of food and beverage section and the space. First, downtown hotels now take on the role of a public facility to a great extent and the number of Koreans who visit the autxiliary facilities of hotel increases. Second, recently revenue from a food and beverage section is in downtown and the trend is especially obrious at western restaurant, buffet and bar. This necessitates the reevaluation of the business space allocation. Third, sales promotion plan includes diversification, dessection and scaling down of the food and beverage section areas, Fourth, a proper number of seats must be determined in regard to the average area of one seat shown in the survey. Fifth, dense seat arrangement would entail a curtailment rather than a hike in revenue. Sixth, the installation of private dining room is on the rise and in particular, in Japanese and Chinese restaurants. Seventh, business space with declined revenue tends to induce the integration of similar businesses.

휠체어에 대한 균형을 맞추지 못하는 체중 배분으로 인해 기존의 휠체어 시스템은 휠체어가 언덕으로 올라갈 때 뒤집히거나 떨어질 위험에 직면합니다. 이 논문에서는 휠체어를 타는 동안보다 안전하기 위해 통합 된 자이로 센서와 틸트 센서를 사용하여 균형을 제어하는 실시간 새 솔루션을 제안했습니다. 휠체어의 전형적인 특성은 발을 움직이는 데 어려움을 겪는 특수 사용자를위한 것이기 때문에 휠체어 시스템의 균형을 유지하는 것이 중요하고 도움이되었습니다. 우리의 방법에서는 경사 센서의 정보를 이용하여 시트 각을 계산한다. 그러나 휠체어가 움직이는 관성의 법칙으로 인해 틸트 센서의 출력 값에 편차가 있습니다. 따라서 자이로 센서의 출력 인 가속도를 이용하여 각도 값을 최적화해야합니다. Gyro 센서와 Tilt 센서의 조합을 사용하여 이점을 얻었습니다. 또한 전체 시스템의 소비 문제도 해결했습니다. ZigBee 센서 모듈을 사용하여 다양한 실험을 통해 밸런싱 시스템의 전력 소비가 크게 줄어 들었습니다.

For many years commentators have requested more active regulation of attorney ethics in international arbitration. Gradual deterioration of ethical standards in international arbitration will bring disrepute and, once its reputation is lost, it could take decades to rebuild confidence. The first reason for increasing unethical behavior is that there is no ethical code generally applied to all lawyers participating in international arbitration. A second reason might be that nobody is actively regulating attorneys in international arbitration. The first step to solve this problem is that major arbitration institutions should cooperate to enact a uniform code of conduct to be generally applied to all attorneys representing parties in international arbitration. Recently, IBA and LCIA prepared guidelines on party representation in international arbitration, and the guidelines will help attorneys follow uniform standardsof ethics. However, this will not be sufficient. There should be a regulating body to monitor attorney ethics and take sanctions against unethical attorneys accordingly. Arbitrators, who can see unethical behavior by attorneys from the closest distance, are the most appropriate regulating force rather than courts of arbitration seat or an attorney's licensing country. Of course, arbitrators don't have powers to withdraw or suspend an attorney's license, but they have powers to control attorneys'behavior within arbitration proceedings such as an allocation of fees and costs, barring the assertion of claims or defenses, drawing adverse inferences, or precluding the submission of evidence or testimony. Furthermore, arbitrators should be provided with such obligation as active control of attorney ethics. Even arbitration institutions should participate by imposing on an attorney who is a repeat offender a suspension from appearing in future arbitrations. Unethical behavior will decrease through concerted actions among arbitrational institutions to introduce a uniform code of conduct and to empower arbitrators for more efficient regulation of attorney ethics.
