At the result of data analysis with sample survey, oriental medicine clinics which treat particular kinds of illness with specialization make the profit of 1.6 times and the expense of 0.74 times more than those which treat general diseases, namely, the former gain the profit of about 2.9 times more than the latter. After excluding other variables which affect in the profit of oriental medicine clinics with multiple regression model, when considering only advantage of treatment for particular kinds of illness, specialized oriental medicine clinics win the more profit of 18.3 percent than general oriental medicine clinics. The specialization of oriental medicine clinics can become one of the positive measures in the situation of enlargement of medical of oriental medicine, falling of oriental medicine price and conflict of western and oriental medicine, etc. The specialization can help western medicine replace with oriental medicine, and level and scientific system of oriental medicine improve. Medical service for particular diseases, one of the better devices for improving profit of oriental medicine clinics, can theoretically make more advantage of oriental medicine clinics through measure of price discrimination than general medicine clinics.

With the limited frequency spectrum and an increasing demand for cellular communication services, the problem of channel assignment becomes increasingly important. However, finding a conflict free channel assignment with the minimum channel span is NP hard. As demand for services has expanded in the cellular segment, sever innovations have been made in order to increase the utilization of bandwidth. The innovations are cellular concept, dynamic channel assignment and hierarchical network design. Hierarchical network design holds the public eye because of increasing demand and quality of service to mobile users. We consider the frequency assignment problem and the base station placement simultaneously. Our model takes the candidate locations emanating from this process and the cost of assigning a frequency, operating and maintaining equipment as an input. In addition, we know the avenue and demand as an assumption. We propose the network about the profit maximization. This study can apply to GSM(Global System for Mobile Communication) which has 70% portion in the world. Hierarchical network design using GA(Genetic Algorithm) is the first three-tier (Macro, Micro, Pico) model, We increase the reality through applying to EMC (Electromagnetic Compatibility Constraints). Computational experiments on 72 problem instances which have 15${\sim}$40 candidate locations demonstrate the computational viability of our procedure. The result of experiments increases the reality and covers more than 90% of the demand.

According to the changing of user and service environment, one of countermeasures that introduction of team-based organization is increasing gradually in the university library. This study was conducted to suggest the efficient ways of assessing team effectiveness which is increasing gradually in the university library. The finding indicated that assessment of team effectiveness was shown large differences according to the working level and individual's working duration. In addition, activated communication and capacity of team-based organization were the most effectible factors on the team effectiveness. So that, for maximizing the team effectiveness, this study might be applicable to any strategy which seek to activate communication methods(within - and between team) those are directly effecting on purpose setting, conflict resolution and suggest suitable team-based organization model for University library's characteristic and purpose through improving on the capacity of team system.

Along with the increase of demand of radio communications and with the rapid progress of communication systems, the radio frequency interference of neighbor nations is a matter of argue. This problem is a delicate matter which must be dealt diplomatically with by having a distinct technical back ground. After the radio interference has been experienced in the Korean TRS service on the south seashore due to the base stations including the Fukuoka station in Japan, the radio interference problem between neighbor nations has become the matter of conflict. For the purpose to solve this problem, we has measured the radio waves that come from Fukuoka in Japan mainly to Pusan in Korea and also collected data in real-time.

The purposes of this study were to identify leadership competences of rural leaders and to analyze leadership competency of leaders. The study carried out by questionnaire and focus group interview on expert panels. To analyze leadership competency, the data was collected from 273 rural leaders by stratified random sampling. SPSSWIN/ver10 program was used for analyzing data with t-test and IPA method. The study suggests twenty low types of leadership competences which were information, vision, decision making, motivation communication, education residents, managing residents, loaming, flexibility, problem solving, presentation program management, customer orientation service knowledge, making relationship, creative idea, business understanding, brand development, conflict resolution negotiation, assessment, business management, coaching and feed back. Whereas leaders with middle school educational career required developing program management, maintaining achievement and benchmarking, leaders with high school were morel likely to develope self-learning, to benchmark their knowhow and brand development competency. Whereas leader with less low years experiences as leader have been considered as developing coaching/feedback brand development and program development, leaders with more five years as leader should consider developing benchmarking, resident education, and brand development. The study suggests that the extension agents on public should develop leadership program according to the competency differences of leaders.

The supplier selection problem is perhaps the most important component of the purchasing function. Some of the common and influential criteria in the selection of a supplier include quality, price, delivery, and service. These evaluation criteria often conflict, however, and it is frequently impossible to find a supplier that excels in all areas. In addition, some of the criteria are quantitative and some are qualitative. Thus, a methodology is needed that can capture both subjective and objective evaluation measures. The Analytic Hierarchy Process(AHP) is a decision-making method for ranking alternative courses of action when multiple criteria must be considered. This paper proposes the AHP-based approach which can structure the supplier selection process and the achievements-based procedure which can allocate order quantities for the selected suppliers In automotive part manufacturers. Also, through the practical case of 'D' automotive part manufacturing company, we shows that the proposed AHP based supplier selection approach and the achievements-based allocation procedure of order quantity can be successfully applied for supplier selection and order quantity allocation problems.

This study investigated preservice teachers' perceived constraints in implementing their ideal pedagogies and the influence of the teacher education program on their pedagogical beliefs changes. Unique features that the university-based coursework and field experiences had on preservice teachers' learning to teach were also explored. This preservice teacher education program employs constructivist aspects of teacher education and generates applications of constructivism to the practice of teaching. Major findings include: preservice teachers' having traditional pedagogy as the default, recovery of prior beliefs, constraints on implementing constructivist pedagogy, and being overly confident in themselves as teachers. With the influence of constructivist epistemology, these preservice teachers' pedagogical beliefs evolved and were refined over time as they incorporated various constructivist ideas. The benefits and influences of the M.Ed. program's theoretical coursework and the field experiences on these teachers' learning-to-teach experiences are addressed with rich data. The implications for teacher educators as well as for the instructional practices of preservice teacher education programs are discussed. Recommendations for future research are also presented.
