The domestic medical device industry compared by advanced nations continues a quick growth, also the level of technique is gradually improving. However, the high import percentage, low investment, shortage of professional manpower and etc. are remained as weaknesses in the competitive circumstance. In this paper I researched world medical device market and industry, and tried to find the development plan of the domestic medical device. The approach could be in mid-long term rather than short-term, The institutional improvement and support of the government, the production complex, the market segmentation and overseas marketing reinforcement and etc. are necessary for export expansion plan.

In order to improve the traffic enviroments in the urban streets of Seoul, the computer controlled traffic signal system was installed on 45 intersections at 1980. Afterward, yearly expansion was done to the numbers of 132 intersections and 232 loop detectors. The problems of timing plans were discussed, mainly pedestrian crossing timing as well as the generations of split and offset. The broad urban streets more than 30m require long phasing time of pedestrians, even though the equivalent or correspondent traffic volume is rare. The configuration of computer system for traffic control was disscussed in terms of control strategy. An overview also given. The improvements were measured at every quater. The travel speed improved to 42%, delay time reduced to 41% and number of stops to 43% respectively.

세계의 방송 통신환경은 글로벌화 되고 있으며 주요 기업간 M&A로 업계 재편이 본격화 되고 있다. 통신산업 환경이 개방화 글로벌화 되어 가는 과정에서 국내 통신산업도 경쟁력을 가지기 위해서는 해외시장 확보와 규모의 경제 달성이 필요하다. 국내 통신산업은 국제적 경쟁력을 갖추고 있음에도 이를 활용한 해외진출은 미흡한 실정이다. 국내 통신사업자가 글로벌 통신시장에 진출하여 해외 통신사업자들과 본격적으로 경쟁하기 위해서는 자본 확충과 다양한 정부 지원이 필요하나 이를 확보하기에 많은 애로점이 있다. 본 고에서는 이러한 문제를 해결하기 위한 하나의 대안으로서 정부의 주요 국정 과제 중 하나인 자원외교와 연계한 통신서비스 산업의 패키지형 해외진출 전략을 제안한다. 본 고에서 제안하는 패키지형 진출 전략의 핵심은 우리나라와 자원부국간의 상생과 자원 IT 금융의 산업간 시너지를 도출하는 데 의의가 있다.

The rapid expansion of regionalism has resulted in the creation of blocs of the global economy, so that those countries not belonging to one or more blocs can be discriminated. The purpose of this paper is to examine the competition policy theoretically, international background with issues, and discussion trend of global enterprise. By doing them, this paper suggests the responsive plan, future prospects, and policy directions for the competition policy by distribution service. There is not a statistically significant relationship between international diversification strategy and firm performance. However, we observed some tendency that the larger the firm size, the higher the firm performance, assuming the degree of international diversification or multinationality to be constant. However, the export productivity increase after 1~2 years, and there exits a clear evidence that the innovation investment increases a firm's export competitiveness as time goes on.

Today the mobile devices including smart phones have influenced on the users' daily activities in the mobile internet society, and the expansion of social media has also affected on the purchasing behavior of consumers. This study examines whether the quality of corporate twitter, a typical social network service for call centers influences on the customer satisfaction, and brand loyalty. In order to achieve the research goal, the quality of twitter has been divided into four variables; information quality, service quality, system quality, and social quality. The results of our empirical analysis show that the three variables except service quality have significantly influenced on the customer satisfaction and the customer satisfaction also significantly has a casual effect on the brand loyalty. The empirical results are expected as a guideline to contribute on the practical improvement of customer service, satisfaction, and brand loyalty through corporate social network services such as corporate twitters in the future.

Spread of internet service had a huge effect on usage and spread of SNS world widely. Variety of the service has increased from human network managing to commerce, education, payment method and so on. Also, it is expanding its service territory to not only PC area but also that of mobile equipment with development of information technology. Spread of use on SNS provides existing corporations the expansion of service area. Late SNS starter companies are advancing in diverse way for attracting users by serving shopping, games and other services with association with SNS. Therefore, analysis on consumers' thought and pattern which analyze users' demand, service's function and contents and other factors in order to reflect on plans and operations of SNS is needed. On this perspective, this research is suggesting properties that are crucially related to sustained usage of SNS and study factors of SNS's characteristics that influence trust and satisfaction on SNS and continuous usage intent of SNS.

Recently, Super-Super-Market(SSM) is facing more and more difficult situation due to the expansion of hypermarket and target marketing of specialized shop. In this situation, Customer Satisfaction Management(CSM) is emerging as a core business factor to make continuous growth without competitive exclusion. Especially, the first factor in CSM in distribution industry is a Service Quality Satisfaction. In this paper, with a selection of 3-markets as a sample for the research, I have tried to look for necessary Service Quality(SQ) factors in SSM and deduced Service Quality Index(SQI), loyalty and Index of detail factor in SQ through survey. Based on these results, strategic factors required to improve SQ was found and strategic directions for SQ were proposed through matrix portfolio analysis.

With increase in oil demand owing to economic growth in Northeast Asia, the establishment of an oil hub in Korea is recently considered by policy and academic circles. This paper aims to suggest strategic schemes on the establishment of Korea's oil hub in Northeast Asia by comparing Korea's conditions as an oil logistics hub with Singapore which has been an oil hub in East Asia until recent year. Quantitative and qualitative analysis methods were employed in order to examine the competitiveness of Korea's oil hub. This research concludes that Korea is very competitive as an oil logistics hub in Northeast Asia, but so much improvements for realizing the project are necessary such as expansion of storage facilities for oil, institutional instruments for facilitating oil logistics and trading and preparation for incentive schemes on foreign investments in oil and its related industries.

This paper proposes IIKBAG(Intelligent Interlocking Knowledge Base Generator) which can build automatically the interlocking knowledge base utilized as the real-time interlocking strategy of the electronic interlocking system in order to enhance it's reliability and expansion. The IIKBAG consists of the inference engine and the knowledge base. The former has an auto-learning function which searches all the train routes for the given station model based on heuristic search technique while dynamically searching the model, and then generates automatically the interlocking patterns obtained from the interlocking relations of signal facilities on the routes. The latter is designed as the structure which the real-time expert system embedded on IS(Interlocking System) can use directly in order to enhances the reliability and accuracy. The IIKBAG is implemented in C computer language for the purpose of the build and interface of the station structure database. And, a typical station model is simulated to prove the validity of the proposed IIKBAG.
