  • Since the mid-1990s, the corporate social responsibility(adhere CSR) has risen as an important issue in Korean company. We have classified 3 effects of CSR activities on corporate performance. That is, this study investigates the relationship between CSR and corporate performance, which are financial performance, marketing performance, human resource and organization performance. Previous literatures discuss how CSR activities influence on corporate performance. But they have not reached at a clear conclusion and the issue is still debate. The relationship between CSR and corporate performance is actually more complicated, so this study is to review literature of various perspective. In this study, CSR management tool proposed for effective and efficiency CSR management by literature review. A right measure is fundamental factor for effective and efficiency CSR management. This study provide fundamental tip for CSR measure using of principles of ISO 26000.

  • Many studies have reported that a lot of nursing colleges do not have good facilities for the nursing practice in hospitals, so many students do not have the good ability which is needed to be a competent nurse. The purpose of this study was to develop a program in which students could improve their ability in fundamental nursing skills before the graduation. This study was primarily designed to identify items of the fundamental nursing practice in which nursing college students have perceived deficiencies. According to previous studies, a total 75 items were presented. In Identifying them, a modified Porter format was used. The questionnaire contained three sections. A. How well do you think you can/could perform the item when you graduate/graduated the college? B. How well do you think you should perform/should be able to perform the item when you graduate/graduated the college? C. How important do you think the item is? For each of the 75 items, the respondents were instructed to answer the above three questions, by circling a number on a rating scale extending from 1 to 5, where low numbers represented a low degree of performance or minimum amount, and high numbers represented a high degree of performance or maximum amount. The perceived degree of deficiency in performance on each questionnaire item was obtained by subtracting the answer to Part A of an item from that to of Part B. The larger difference means a larger perceived degree of deficiency in performance. This method of measuring the perceived degree of deficiency in performance is an indirect measure derived from two direct answers by the respondent for each item. From this result Part C of each item was used to rank the items, and the items were prioritized. The items which had the highest priority were IV injection, simple catheterization, indwelling catheterization, CPR, and nurse recording. By this method, through these results from a nursing college, and the items which will be used first in developing the supplementation program for nursing college students can be identified.

  • In recent years, along with the advances made in performance-based design optimization, the need for fast calculation of response parameters in dynamic analysis procedures has become an important issue. The main problem in this field is the extremely high computational demand of time-history analyses which may convert the solution algorithm to illogical ones. Two simplifying strategies have shown to be very effective in tackling this problem; first, simplified nonlinear modeling investigating minimum level of structural modeling sophistication, second, wavelet analysis of earthquake records decreasing the number of acceleration points involved in time-history loading. In this paper, we try to develop an efficient framework, using both strategies, to solve the performance-based multi-objective optimal design problem considering the initial cost and the seismic damage cost of steel moment-frame structures. The non-dominated sorting genetic algorithm (NSGA-II) is employed as the optimization algorithm to search the Pareto optimal solutions. The constraints of the optimization problem are considered in accordance with Federal Emergency Management Agency (FEMA) recommended design specifications. The results from numerical application of the proposed framework demonstrate the capabilities of the framework in solving the present multi-objective optimization problem.

  • This study was conducted in order to find an ideal working fluid kind and a proper filling amount in the heat pipe as well as an inclined angle of heat pipe when they are placed to recover exhaust gas heat in the hot air heater. Followings are the findings of this research. 1. Of the four different working fluids-gasoline kerosene distilled water and acetone-acetone filled heat pipe showed the best performance giving out more homogeneous temperature profile on the radiating part than the kerosene and gasoline heat pipe an carrying out heat transmitting function better than the distilled water heat pipe by 10~2$0^{\circ}C$ higher on the radiating part. Acetone would be a good choice for recycling of exhaust gas heat in the hot air heater. 2. Of the filling amount of working fluid inside the heat pipes dry-out situations possible caused by insufficient filling were found in the filling amount of 5, 7.5 and 10% heat pipes as heat supply rate increases gradually in the range of 50 to 15kJ/sec. but no dry-out and stabilized heat transmitting performance occurred in the heat pipes of 12.5 and 15% filling at the same heat supply rate. It recommends that filling amount shall exceed 12.5% at least with the working fluids of this experiment. 3. The test revealed that the heat transmitting performance of heat pipe was more affected by filling amount rather than inclined angle.

  • CISG provides the Convention's default provisions on anticipatory breach. Article 71 permits the aggrieved party to suspend the performance of his obligations if it becomes apparent that the other party will not perform a substantial part of his obligations after the conclusion of the contract. The aggrieved party must give notice of the suspension to the other party and if he provides adequate assurance of his performance, the party must continue with performance. Article 72 authorizes the aggrieved party to avoid the contract to the date of performance when it is clear that the other party will commit a fundamental breach. The aggrieved party is also required to give the other party notice of his intent to avoid the contract if time allows. The requirements for avoidance under Article 72 are more stringent than those for suspension under Article 71. Article 72 requires reasonable prior notice only if time allows, while article 71 requires immediate notice with no exceptions.

  • We have analized the inverse class-F and class-F amplifiers using their waveforms. From the analytic equations derived from the analysis, we have calculated tole efficiencies, output powers, DC power dissipations, and optimum fundamental load impedances of the inverse class-F and class-F amplifiers. We also have compared them for various operation conditions, which include the same peak current, saute DC power dissipation, same fundamental RF output power, and same fundamental load impedance with different Ron(on-resistance). These analyses have clearly shown the performance limitations, advantages, and guide to the optimized design of the inverse class-F amplifiers.

  • Contract design plays a key role in the life cycle of BOT project. All project management activities and operation processes are arranged in consistence with the document of BOT contract which the public sector ensures that the respective roles and responsibilities set out in the contract are fully understood and fulfilled to the contracted performance criteria. With limited theories to deal with some fundamental issues of BOT contract design, we try to collect data from case studies and formulate several practical principles. The conclusions presented in this paper are analyzed from two cases, one is based on an early case in the United Kingdom, and the other based on the Taiwan High Speed Railway case. The purpose of this paper is not about covering all legal issues about BOT contract design, but rather, our work provides common considerations applicable to the contract parties of a broad range of BOT contracts. The results in this paper shall propose some fundamental principles of the BOT contract design.
