  • DSR(Dedicated Short Communications)는 ITS 서비스를 지원하기 위한 이동 통신 방식으로서 교통 정보 서비스에 적합하다. 그러나 ITS에서 일반적인 데이터 서비스를 지원할 경우에는 기존의WAC (Wide Area wireless Communications) 방식을 고려할 필요가 있다. 특히 이동통신 망에서의 무선 인터넷 서비스 지원을 위한 활발한 연구를 고려할 때, ITS에서의 인터넷 서비스 지원은 고려할 가치가 있다. DSRC의 무선 구간 에러 및 흐름 제어를 담당하는 LLC(Logical Link Control) 프로토콜은 교통 정보 서비스를 지원하기에는 적합하나, 영상, 지리정보, 인터넷과 같은 서비스에는 효율적이지 못하다. 그 이유는 서비스에 따라 데이터의 트래픽 특성이 달라지기 때문이다. 따라서 본 논문에서는 DSRC에서 교통 정보 서비스뿐만 아니라 인터넷 웹 서비스까지 효율적으로 지원할 수 있는 LLC 프로토콜을 제안하고 그 성능을 분석한다. 성능 분석의 결과, 제안된 알고리즘이 교통 정보 서비스에 대해서는 일본과 유럽에서 제안된 DSRC LLC 프로토콜과 동일한 성능을, 인터넷 웹 서비스에 대해서는 우월한 성능을 나타냄을 확인하였다.

  • Consumer needs becomes various in a mature mobile telecommunication market, while service differentiation is hard to achieve. The competition among telecommunication service providers is getting fierce in order to maintain and obtain customers. Moreover, HSDPA caused the intense marketing activity for the move to the next generation customers. Under these circumstances, brand equity can be a key to a long-term competitive edge for mobile phone service providers. In this study, we identified the factors influencing mobile telecommunication brand equity, and its influence on the HSDPA service subscription behavior.

  • The Internet banking service, through which customers process their banking-related works, was introduced in July 1997. The service has since spread quickly, and as of the end of June 2000, just one year after its introduction into Korea, its subscribers numbered 1.23 million people. This figure is ten times larger than the 120,000 subscribers recorded over the six months period up to the end of 1999. In addition, since the end of June 2000, subscriptions on average increase by more than 10,000 a day, and by the end of December 2000, it is expected to pass the 3 million mark. There has been no empirical study conducted on the invigorated Internet banking's status and its services. Therefore, this research is designed to conduct a survey on the Internet banking service status, to conduct actual transactions from the viewpoint of customers and then make a empirical evaluation of it. This will indicate directions for improvement and development of the domestic Internet banking service. We have evaluated ten areas of the Internet banking service including financial service, customers service, users'convenience, and system safety. As of the end of June 2000, 18 out of 20 commercial domestic banks are providing an Internet banking service, and we have conducted evaluations of all these banks. The evaluation is divided into ten categories with 100 points as a maximum score. These are then classified into six grades AAA, AA, A, BBB, BB and B. The outcome of this evaluation was featured in the major domestic journals, and the banks, acknowledging the value of the report, declared that they would adopt it as their criteria for evaluation.

  • Quality has long been considered as an important factor in creating competitive advantage, and researches on quality have not been limited to off-line products but actively extended to e-services and information goods. However, given the nature of multi-dimensional aspect of quality, the systematic study on the quality of online service is still in its early stage. Especially, studies on the quality of ASP services have been rare in academic and professional journals despite the growth of ASP industry in its size and the rapid expansion in the range of application. In this paper we clarified the multi-dimensional quality aspects of the ASP service using a Garvin's framework (1984) which encompasses the service aspects of Products, and developed a measurement model for ASP service qualify. Then we empirically tested the effects of ASP service quality on user satisfaction and perceived firm performance using the data from 240 Korean small firms with less than 50 employees that had experienced the ASP service. Our results show that there are positive relationships among ASP service quality and personal performance, user satisfaction and perceived firm performance, and that product and service-related aspects of ASP service exert differential effects on performance measures so that the product-related aspects of the ASP service such as performance, features, reliability and conformance are considered to be more important in evaluating benefits from ASP services. Contrary to the approaches In literature where only the quality of online services is evaluated, our results emphasize the importance of differentiating Product and service-related aspects of ASP service and provide a basis for more comprehensive evaluation of ASP service quality.

  • To solve the traffic problems of small cities like Chung Ju City, electronic communications equipment and the introduction of advanced technologies are being used or promoted. Other local areas with developed systems in place are being investigated for applicability. Systems like these will be introduced. This system will embody an organized, efficient transportation and safety system within this study At the moment, to solve the problem of reoccurring traffic in small towns in our country, we must develop an ITS service. We are now in the process of selecting and establishing the most adaptable ITS service to a small city For this purpose, we have studied existing records; taken a poll of the citizens of Chung Ju; examined present traffic conditions, examined road capacities; and reviewed available means of transportation. To accomplish the purpose of a thesis like this, we will research and analyze developed nations' and domestic cities' existing systems, construction and operation. We are in the process of building an ITS System which is the most adaptable to a small city like Chung Ju.

  • The rapid growth of investments in mobile service to reach a large and growing body of customers, coupled with low communication costs, has made user acceptance an increasingly critical management issue. The study draws upon the task-technology fit (TTF) model as its theoretical basis and its empirical findings to pragmatically explain the key factors that affect the performance and user acceptance of mobile service in medical field. A total of 110 usable responses were obtained. The findings indicate that the task, technology, and individual user characteristics positively affect task-technology fit and mobile service usage. The task-technology fit and mobile service usage are the dominant factors that affect mobile service performance. The result points out the importance of the fit between technologies and users' tasks in achieving individual performance impact from mobile service in medical arena.

  • This is an empirical study on Korean traditional restaurant service providers and customers who get direct service from them. This study focuses on the service performance determiners; customer satisfaction, service quality, service providers' satisfaction and loyalty. In order to meet its purpose, we survey 1,000 customers who have visited Korean traditional restaurants. This survey uses the SERVPERF service quality measuring theory. The results are as follows: First, the service providers' satisfaction have an effect on service quality, so the supervisor of a Korean traditional restaurant should construct a HRM (Human Resources Management) system for increasing employees' satisfaction. Second, employees' loyalty is significant, but its effect is lower than their satisfaction. Third, service quality affects customers' satisfaction and loyalty significantly. Fourth, employees' satisfaction and loyalty considerably influences customers' satisfaction and loyalty. Consequently, restaurant managers put their effort into increasing employees' satisfaction, loyalty, and service quality.

  • 본 연구의 목적은 금융기관 서비스품질의 만족도를 높이고 충성도 있는 고객을 확보하여 지속성장 가능한 수협은행 관련 연구가 현실적으로 부족하였다는 문제의식에서 출발하였다. 본 연구결과에서 수협은행의 서비스품질을 위한 제고방안은 결정요인 결과를 토대로 유용성 흥미성 신뢰성 안전성의 고객만족과 고객관계관리 관계성을 정립하여 고객의 니즈에 맞는 새로운 욕구를 고려하는 제고방안이 수립되어야 하며 유의수준이 높은 내적품질 요인을 높일 수 있는 서비스 품질의 제고방안을 맞춤형 서비스로 확대 시킬 필요가 있다. 급변하는 금융환경의 변화에 맞게 전문경영인 체제와 능력위주의 인사정책 도입으로 수협은행에 사회적, 경제적, 가족적, 문화적 변화 특성을 정확히 이해하고, 그러한 변화에 대응할 수 있는 프로그램 개발 운영이 필요하다.
