After social service voucher schemes were introduced in Korea, many controversies have been concentrated on market-based approach, which encourage competition and choice while amount of funding, number of providers, and types of services have been rapidly expanded. This also could mean that transform of social service paradigm from provider-centered approach to user-cantered approach, one of the trends found internationally. Therefore, this is the study to reveal development of social service discourses in Britain where various models of social services have been attempted in their modern history. Then, through the historical analysis, the trends toward more user-cantered approach were found to be distinguished based on the division of individualism and collectivism. This could provide theocratical implication to the current discussion on social services in Korea.

As express courier market expands rapidly, companies are exposed to fierce competition. To cope with struggle for their survival, they are continuously making efforts to improve their service system. Even if most of service centers are directly linked to a consolidation terminal in courier service network, some of them with regional disadvantages are operated in milk run type from/to the consolidation terminal, which is a traditional PDP (Pick-up and Delivery Problem). This study suggests an approach to solve the PDP with the objective of maximizing the incremental profit, which belongs to PTP (Profitable Tour Problem) class. After the PTP is converted to TSP (Traveling Salesman Problem) with the same objective, a heuristic algorithm based on GA (Genetic Algorithm) is developed and examined through an example problem in practice of a courier service company in Korea.

The advanced computer network technology enables connectivity of computers through an open network environment. There has been growing numbers of security threat to the networks. Therefore, it requires intrusion detection and prevention technologies. In this paper, we propose a network based intrusion detection model using FCM(Fuzzy Cognitive Maps) that can detect intrusion by the DoS attack detection method adopting the packet analyses. A DoS attack appears in the form of the Probe and Syn Flooding attack which is a typical example. The SPuF(Syn flooding Preventer using Fussy cognitive maps) model captures and analyzes the packet informations to detect Syn flooding attack. Using the result of analysis of decision module, which utilized FCM, the decision module measures the degree of danger of the DoS and trains the response module to deal with attacks. For the performance comparison, the "KDD′99 Competition Data Set" made by MIT Lincoln Labs was used. The result of simulating the "KDD′99 Competition Data Set" in the SPuF model shows that the probe detection rates were over 97 percentages.

As competition for better service between corporations is getting fierce, many efforts to improve service quality are being made endlessly. The quality of service is directly associated with customer satisfaction and the employee performance of emotional labor is a key factor to attain a high level of customer review and better corporation image. This study examines an influence of emotional labor on job stress and customer orientation in the context of a service franchise firm. The results are as follow. First, deep acting of emotional labor has a negative influence on job stress, and surface acting of emotional labor has a negative influence on customer orientation. Also, job stress has a negative influence on customer orientation. Second, deep acting of emotional labor does not have a positive influence on customer orientation. Third, surface acting of emotional labor does not have a positive influence on job stress. The findings of this study show that deep acting of service based on an employee emotion can produce the employee's better service attitude by decreasing employees' job stress, but standardized surface acting of service cannot. Therefore, franchisor needs to use employees' deep acting to improve the franchisee service quality.

The introduction of reseller In Australian Fixed Telecommunication Market resulted in the reduction of Telstra's local call market share by 13 percent and average fall rate was reduced. Thus, Telstra increased basic rate at 14.5 percent to compensate loss revenue in the local call market. With the deployment of carrier pre-selection of long distance and international calls, it reduced long distance rate at 23.5 percent and international tall rate at 53 percent, and increased the Churn rate. Therefore, the deployment of service-based competition brought efficient results for long distance and international call market. However, LM market created 13.4 percent reduction in call rates, complications in charge system, technical barriers and the preference of one-bill by customers.

As the high-speed internet access market steadily nears its maturity phase, growth is quickly tapering off and competition, intensifying. As a result telecommunications companies are at present faced with the urgent need to evolve away from a growth model based on continuous acquisition of new subscribers. The recent convergence of telecommunication and broadcasting has come about precisely at this transitional period in the telecommunications market, and is perceived by the industry both as a new business opportunity and as a threat. TV-based VOD(Video on Demand), for one, is able to attract new customers desiring multimedia services of superior quality and to lock-in existing customers. Meanwhile, the latest evolution in network development is brightening the market prospect for TV-based VOD. The service has now hit the market, deployed over VDSL networks - a next-generation high-speed internet - and advanced cable modem networks, delivering high-definition DVD-quality videos. TV-based VOD is a service whose deployment is closely linked to the evolution of subscriber networks. According to the forecast produced by the present study, based on the forecast on the post-ADSL market and a survey conducted on VOD, as post-ADSL subscribers increase from 1.53 million in 2003 to 4.44 million in 2004, and 9.87 million in 2006, the percentage of post-ADSL subscribers with intention to also subscribe to a VOD service is expected to rise from 16% to 34% in 2006. Accordingly, VOD subscribers are estimated to increase from 0.24 million in 2003 to 0.98 million in 2004 and to 3.35 million in 2006.

We consider a consumer self-selection model in which a regulated firm faces two market segments with differing valuation of quality of telecommunication services and examine some economic implications from the behaviors of the firm. In the context of a regulated monopolist, even though the results depend on the degree of privatization, the firm could lower the quality of the low-end model and reduce the price of the high-end in order to alleviate cannibalization. This justifies the provision of universal service policy in the telecommunications market. Based on this self-selection model, we also analyze an extended model of product introduction and show that the monopolist will introduce new product with the same introduction time of social planner. However, when we consider competition among firms, the market equilibrium may not guarantee the efficient time of product introduction.

The competition between hospitals has become an issue for many hospitals because of the sudden increased number of health providers. As the marketing or customer management have become important factors as means of competition, a number of hospital have been considered or already adopted the coordination system. A system dynamics model is developed to see the effect of the hospital coordination system. This paper after briefly explaining the structure of the system dynamics model, discusses the roles of the hospital coordination system with examples. The system dynamics model quantifies through simulations the process of effects of coordination system on the number of customers, productivities of employees (nurses and doctors), and finally the financial status. As a conclusions of the simulations and their analysis, it is concluded that coordination system could be more effective than the investment to the facilities. Since the study is based on only one hospital case, it is limited. However, it explains the mechanism of the coordination system quantitatively as well as qualitatively.
