TSR (Trans-Siberian Railway) route is losing price competitiveness versus Deep Sea route in the transportation from East Asia to Europe, including Moscow. To further attracting the containers to the TSR route, it will be necessary (1) to keep competitive through rate, linked to fluctuating Deep Sea rate; (2) to strengthen speed advantage; (3) to enforce seamless transportation system, including simplified customs clearance procedures. In transportation to Central Asia from East Asia (Korea and Japan), TSR is competitive versus TCR (Trans-China Railway), depending on destinations. Korea has been the leader in revitalizing the TSR route since 2000. Key contributors were affluent export containers to Russia and Central Asia, port of Busan, efficient maritime transport network to Far East Russia, and Korean forwarders' persistent efforts for activating the market. Korea and Japan have a possibility of cooperation in using the TSR route efficiently, such as organizing a joint block train to a same destination.

This paper presents a methodology to find the profit maximized Nash Equilibriums of each generator(or GenCo), which considers the Ramp-rate of each generator under a competitive market environment. The ramp-rate of a generator is one of the physical or technical constraints of a generator and means the ability to increase or decrease the output instantaneously. In this paper, we found several Nash Equilibriums of the generation allocation problem through Dynamic Programming in a competitive market. Individual generators participate in a game to maximize its profit through competitions and play a game with bidding strategies of its generation quantities in a spot market.

The purpose of this study is to investigate the relationship between organizational culture types and organizational effectiveness in the hospitals and to identify the cultural and organizational characteristics of the hospitals with high organizational effectiveness. Data were collected from May 12 to June 14. 1997 through questionnaire taken by 1.118 nurses working in 10 hospitals with more than 800 beds and from annual reports published by the hospitals. The instruments were used for collecting the data: Organizational Culture Questionnatire and Organizational Characteristics Questionnatire developed by the researcher. Mowday's Organizational Commitment Questionnaire. Taylor & Bovver's General Satisfaction Scale. The Results were as follows: 1. The meta culture of the hospital organizations was the conservative culture. 2. There were significant differences of the four organizational cultural types - affiliative culture. innovative culture. conservative culture. task culture among the hospitals(p=.00). 3. The hospital organizations were classified in to three cultural patterns. each of which had similar cultural composition. on the basis of the scores indicating the similarity and difference of the foul' organizational cultural types among the hospitals. The organization of each group represents conservative- dominant culture. innovative-dominant culture and competitive culture. 4. Nurses' organizational commitment and job satisfaction were significantly different among the cultural patterns(p=.00). In other words. the hospitals with innovative-dominant culture showed higher organizational commitment and job satisfaction than ones with conservative-dominant culture and competitive culture. And also. the growth rate of outpatients and inpatients were significantly different among the cultural patterns(p<.05). The hospitals with innovative -dominant culture showed higher growth rate of outpatients and inpatients than ones with conservative-dominant culture and competitive culture. 5. The hospitals with conservative-dominant culture and competitive culture showed higher level of centralization than ones with innovative -dominant culture(p=.00) And the hospitals with competitive and innovative-dominant culture showed higher level of communication than those with conservative-dominant culture(p=.00) Finally. the hospitals with innovative-dominant culture showed higher level of managerial strategy than those with conservative-dominant and competitive culture. among which the latter showed higher level of managerial strategy than the former(p=.00).

This paper studies a novel method to find the profit-maximizing Nash Equilibriums in allocating generation quantities with consideration of ramp-rates under competitive market environment. Each GenCo in a market participates in a game to maximize its profit through competitions and play a game with bidding strategies. In order to find the Nash equilibriums it is necessary to search the feasible combinations of GenCos' strategies which satisfy every participant's profit and no one wants various constraints. During the procedure to find Nash equilibriums, the payoff matrix can be simplified as eliminating the dominated strategies. in each time interval. Because of the ramp-rate, generator's physically or technically limits to increase or decrease outputs in its range, it can restrict the number of bidding strategies of each generator at the next stage. So in this paper, we found the Nash Equilibriums for multi-stage generation allocation game considering the ramp-rate limits of generators. In the case studies, we analyzed the generation allocation game for a 12-hour multi-stage and compared it with the results of dynamic economic dispatch. Both of the two cases were considered generator's ramp-rate effects.

In recent years, electric industries in many countries confront with a structural change in business and socio-economic environments. Since 1984, PUC and utilities in U.S.A. have adopted or developing competitive bidding systems, and this new procurement programs prevailing and restructuring the power markets. In Korea, government and the Korea Electric Power Corporation (KEPCO) invited the private sector to build and operate two 500 MW coal plants and two 400 MW LNG plants during 2001 - 2004. The plan also specifies basic concepts and conditions for the IPP projects such that new IPPs are selected through competitive bidding system with the purchased power price based on the avoided cost. In this study, the direction, guideline and scoring methods to Korean IPP bidding system are presented. Also, as a benchmark price and rates for purchased power, the avoided cost calculation models are developed, this study may contribute for the development of private power in Korea, and improve overall economic efficiencies of whole electric power sector.

The development of Korean shipping industry is maybe defined into three development stages-industry fixing stage, industry coordinating stage, industry development stage-. The development of shipping industry has been depended on the geovernment/authority role such as shipping policy, system, law, rules and regulations. In 1983, Korean shipping industry reorganization and coordination by shipping authority have made our shipping industry on the stable condition together with each company's efforts. Today's world economic environment such WTO/UR negotiation results get this government role limited. According to the being reduced government role, each company's competitive advantage power becomes more important. Besides, korean shipping industry is exposed into the entire and bitter world competition. In order to win and prevent the world shipping competition, it is necessary to look out the competitive advantage power of Korean shipping industry. The first purpose of this study is the situation analysis for competitive advantage power of Korean shipping industry. The second is to compare with our shipping policies with foreign ones concerned with ship, cargo, crew, tax and others. But in order to compare with foreign shipping, this study need their shipping statistics data, this study has some limit of the foreign data. This study has been carried on the basis of the following items. 1. Shipping environment, 2. Ships and ship acquirement(shipbuilding/purchasing), 3. Oceangoing cargo and ship's stowage rate, 4. Human factor in shipping-crew, 5. The incomes and costs in finacial statements. We have some conclusions as following through the this study. First, Korean shipping industry environment-competitive disadvantage situation- has changed rapidly due to the shipping market opening, free market entering of foreign shipping. Second, Korean shipping is disadvantageous due to the high tax rate and financing conditions in connection with ship acquirement. In order to improve the competitive advantage power, the shipping tax system and ship financing conditions should be reviewed to profitable for owners. Third, but both world and Korean oceangoing cargoes quantity have been increased annualy, Korean ship's cargo stowage rate is being decreased. This is serious situation but Korean shipping take well use of foreign vessel with hire. It is recommended to take use of owner's vessel and hired ones in the long range view, considering the world shipping management. But the number of crew has been decreased by 2, 000~3, 000 annualy, it is desirable that the long sea-experienced crew have been increased. Almost of owners usauly complain the crew cost is the main obstacles to competitive advantage power. Human factor is the most important firm's asset. All owners should pay attention to this though, and invest the proper budget to training, education, welfare as much as possible. In the long run this effects could be feedback to owners. Fifth, We must improve the financial statements structure, that is, the first step is to increase income, the second is to decrease cost, the third is to increase income on the same cost, the fourth is to decrease cost on the same income. It is essential to find out what the urgent investment is and what unnecessary cost is. At last, in order to competite world shipping race, each shipping firm must try for himself to retain the power. The government/authority is no longer dependable. I believe that each firm's power will be the industry's power, the industry's power will be the nations's power.

In acquiring and transferring a superior knowledge assesing the intermediate result value of a competitive R&D project is very important for a firm engaging in R&D. Most existing literatures on R&D evaluation are concerned with project selection and resource allocation. In this paper the stage of an R&D project is classified into research, exploratory development, and development. And a model is suggested which evaluates the intermediate result value before completion of development stage under duopoly and oligopolistic competition. Assessed value of the intermediate result transferred to the next tier company can be used as a minimum acceptable price to the inventor when more advanced knowledge acquired through R&D is transferred to the next tier one. The model suggested is composed of structural variables including research cost, success rates, potential profits, discount rate degree of competition. By using exponential distribution for invertion process time in each stage, we derive a formula that can assess the value of the intermediate result, and we demonstrate how the model can be applied to a competitive R&D situation through an example.

At the moment, Korea has faced a big challenge to an economic crisis due to higher exchange rate against foreign currency. In order to escape from this type of economic crisis quickly, our professional engineers have to do every endeavor to develop the basic material industries so that we could produce our product with a competitive price. If we were not victorious in this of borderless game, we would be hungry again very shortly.

Objectives: This study tried to use information from the university information disclosure system as basic data to understand dental hygiene departments and search for development directions by analyzing major indicators through information disclosure data collection. Methods: Based on the information released from 2019 to 2021, 53 three-year universities with dental hygiene departments nationwide were analyzed based on data from the last three years of university alerts. Results: The indicators that the colleges with dental hygiene departments had higher averages than the overall junior colleges were: rate of levy with enrolled students within the quota, rate of faculty in full service, rate of lectures conducted by faculty in full service, employment rate, and annual scholarships per person. In the dental hygiene departments, acceptance rates of new students were 1.46-30.53 (average 10.24), admission quota was 27-160 (average 70), the number of continuing students was 39-515 (average 209), number of scholarships was 1,368,348.50 won-4,581,073.13 won (average 3,515,647.32 won) and the employment rate ranged from 57.6% to 98.9% (average 82.8%). Conclusions: In order for the departments of dental hygiene to be competitive, it is necessary for colleges to find ways to increase pride in, and satisfaction with their departments. After graduation, if the professional dental hygienist system is established and the legal role as a dental hygienist is expanded, it will be possible to move forward as a competitive department.

This article aims to validate empirically and verify theoretically, the applicability of the spa town life cycle model to Bath Spa located in United Kingdom. In order to test the model, the indicators of the model that associated with the rate of transportation infrastructure, the length of stay, tourist facilities, competitive resorts, advertising, tourism policy, environmental problem and the attitude of residents were examined through a comparative analysis. According to the result of this research, the indicators of 7 items excepting competitive resorts applied to Bath Spa. The competitive resorts of Bath Spa emerge at the maturity stage differing from the model that appeared at the stagnation stage. In conclusion if the new hypothesis of competitive resorts is added to the model, the model will be applied to western spa town, which has a small scale and a long history.
