다수의 사람과 파일을 공유할 수 있는 웹하드 서비스의 이점을 이용하여 각종 불법복제물 등의 업로드를 유도하고 다운로드를 통해 이득을 취하는 특수유형의 OSP(Online Service Provider, 온라인 서비스 제공자)들이 출현하게 되었다. 이런 범죄가 일어나는 업체의 데이터베이스에는 모든 이용자들의 관련 기록을 담고 있어 헤비업로더의 활동내역뿐만 아니라 업체측의 방조혐의 등의 증거를 추출할 수 있다. 본 논문에서는 특수유행 OSP들의 대용량 데이터베이스를 신속하고 정확하게 무결성을 유지하며 데이터베이스의 데이터를 수집할 수 있는 방법에 대해 연구해보고, 수집한 데이터 또한 신속하게 분석하는 방법을 제안하였다.

Purpose: This research aims to analyze the service process of corporate courier services in order to offer service providers possible directions for adaptation of new technologies and assurance of better quality services. Methods: Through the analysis on the parcel service process of company Y by applying service blueprinting method, the overall process and failure service points of corporate courier services can be recognized and investigated. Next, the several newer technologies, augmented reality glasses, exoskeleton, and drone are applied to the service process of company Y as they are suggested by the literature review and referenced to DHL's report on the Fourth Industrial Revolution. Then, service options to overcome the service failure points to improve the service process can be produced. Results: The parcel service process of the company Y is utilized as a hub-and-spoke structure by having distribution and delivery centers which separates customers into two types, ones using the total services and the others only using the delivery service. In addition, the main cause of the service failures is determined that it is due to the limited working hours of delivery centers compared to the workload. Conclusion: This research contributes in better understanding of corporate courier services and providing information for benchmarking. An empirical research on the costs and the efficiencies of applying the new technologies is suggested for the further improvement in the processes of corporate courier services.

Recently, the number of available cloud services are increasing dramatically because many IT companies have entered into cloud service market. Due to the reason, cloud service brokers are emerging as agents to solve cloud service selection problems and to support cloud service initialization and maintenance of unskilled cloud service users. In this study, NCloud24 case in South Korea and Right Scale case in the USA are analyzed as representative examples of the collaboration between original cloud service providers and cloud service brokers. The business models of two companies are analyzed using Business Model Canvas. The emergence of cloud service brokers are interpreted as unbundling process of IaaS (Infrastructure-as-a-service) cloud service companies. Based on the comparison with the two companies, we prospect future directions of cloud service brokerage.

As the research and development(R&D) has become a necessary motive in social development, the importance on the evaluation of the technical information service is also emphasized. Among others, the economical evaluation and the productivity of the technical information service are very complex and complicated as of the information value. Also the technical information service is influenced by its infrastructure. Therefore, the economical evaluation on the productivity of the technical information service requires a more systematic and complex approaches simply to be more objective and rationalized.

The main objective of this research is to develop a model to select the optimal input service level for a distribution center - multi branch inventory distribution system. With the continuous review policy, the distribution center places an order for specific order quantity to an outside supplier, and the order quantity is replenished after a certain lead time. Also, each branch places an order for particular order quantity to the distribution center to satisfy the customer demands, and receives the replenishment after a lead time. When an out of stock condition occurs during an order cycle, a backorder is placed to the upper level to fill the unfilled demands. With these situation, variable demand and variable lead time are used for better industrial practice. Further, actual lead times with a generic lead time distribution are used in developing the control model. Under the actual lead time model, the customer service measures actually attained for the distribution center and each branch are explained as the effective customer service measures. Thus, throughout the optimal control (using computer search procedures), we can select the optimal input service levels for the distribution center and each branch to attain the effective service level for each branch which is consistent with the goal level of service for each branch. At the same time, the entire distribution system keeps minimum inventories.

Recently, DMB service markets experience a rapid change with terrestrial DMB test-broadcasting for the nation-wide coverage and paid interactive data broadcasting being offered utilizing TPEG and BIFS technologies. This warrants a reexamination of a consumers' adoption intentions for DMB service. This paper uses a survey data set to analyze DMB adoption intentions and the choice between terrestrial DMB and satellite DMB services according to preferred contents and other media usage characteristics. Empirical results show that consumer who prefer TV, music, and movie contents are more likely to adopt DMB service, whereas consumers with high intentions for HSDPA subscription are less likely to adopt DMB service. This implies that continuing development of killer application and the analysis of substitutes or complements of other media are crucial for the increase of DMB adoption intentions. It is found that the more consumers prefer sports, movies and entertainment/game and put higher values in the quality of the contents, the more likely they adopt satellite DMB service. Meanwhile, the more consumers prefer TV, drama and news contents, and are sensitive to the subscription fees, they are more likely to adopt terrestrial DMB service. Therefore, it seem that consumers' DMB adoption between terrestrial and satellite services is crucially related with types and characteristics of contents offered.

This study aims to analyze what is necessary for realization of convergence smart city service, and what is the priority order for it. First, the concept is set up through the theoretical review about convergence smart city service. Second, conduct in-depth interviews with smart-city related experts and derive the necessary elements to implement convergence smart city service. Third, derive priorities by subdividing the derived elements and utilizing the AHP method. The result of this study is expected to contribute to the development of convergence smart city service by deriving what should be considered for implementation of convergence smart city service.

The purpose of this research is to study the effect of service qualify improvement strategy and its practices on firms' competitive advantage, and identify their influence on customer satisfaction and loyalty. According to this purpose. this paper hypothesized that high service qualify will satisfy customers' needs and result in improved customers' loyalty. Thus, empirical study was conducted to identify the relationships among factors which were identified through literature review. Data were collected from the customers of 3 luxurious japanese restaurants in Seoul. The result of data analyses shows (1) Serve quality factors such as customer service, qualify of meal, location and facility, and types of restaurants make significant difference among three restaurants in terms of customers' perception about service quality; (2) There is statistically significant difference among three restaurants in terms of customers' satisfaction, but there is no significant difference among them in terms of customers' loyalty; and (3) Not only the result from analysis on japanese restaurants inside hotels but also that on the independent japanese restaurant in Kangnam area, shows that service quality factors have significant effect on both customers' satisfaction and loyalty.
