It is expected that the next generation mobile communication system will be a service-driven developed system capable to realize the human-centric mobile convergence services. and it is different from the technology-driven development approach of the second and the third generation mobile communication systems. As a preliminary research work on such service-driven system development approach for the next generation mobile communication system. we developed the scenario based service analysis process (2SAP) framework to derive core service technologies and functionalities. In this paper. we propose the next generation mobile convergence service business model creation methodology based on research results of the 2SAP framework. To achieve this goal, we first establish a service model contains several components such as infrastructures. operations. and provision of services that are indispensible for providing next generation mobile services. Then, the next generation mobile services and its corresponding business models can be created by adding service and value flows to the developed service model after defining necessary components of business model including actors, their relationships, and roles.

A notable recent change in Korean social service delivery is adopting voucher system. A significant portion of foreign literature suggests that the structure of service provision is critical to enhance consumer choice in voucher-based social service delivery system. As domestic research on voucher operation system is very limited, little is known about voucher-based social service provision structure and operating system. Given these limitations in the domestic literature, this study aims to examine the status and effectiveness of voucher-based system with specific focuses on the provision structure of early intervention service for children at the risk of ADHD. Data were collected from 194 service providers across the nation. Based on Cave's analytic paradigm on voucher operating system, data analyses were done to examine (1) the influence of adopting voucher system on service provision system and (2) whether consumer choice has been increased or not. The results indicated that (1) adopting voucher have brought into diversification of service providers, but (2) consumer choice is still limited. Based on these results, future directions for voucher-related policy were discussed.

The aim of this study was to understand the management level of pathogenic bacteria in HACCP system implemented animal farms. Microbial samples were collected from manure, floor, compost depot, manure on belt, low milk tank, dust in laying house and egg collector in HACCP system implemented Korean beef cattle, dairy cattle, swine, and laying Hens farms. O157, O111 and O26 strains of E. coli were not detected in HACCP system implemented Korean beef cattle farm. The detection rate of E. coli from manure and floor in HACCP system implemented cattle farms (Korean beef cattle and dairy farm) was lower than those of non-HACCP system implemented cattle farm. Salmonella spp. was detected in HACCP system implemented cattle farms (Korean beef cattle and dairy farm). Compared with pervious studies, lower detection rate of Salmonella spp. at floor and compost depot in HACCP system implemented swine and commercial layer farms were indicated. In conclusion, implementation of HACCP system in animal farms would enhance the management level of biological hazard compare to normal animal farms.

The purpose of this study is to find determinants for service mind and skills of hospital employees to seek ways to improve the service level of hospitals. The past studies focused on the perspectives of customers in finding the solutions for service improvement. However, the existing approach failed in delving into the whole picture of service system. The behind operation of service system(e.g., selection and training of employees, support system) needs to be examined to have a balanced solution of service improvement. The personal characteristics, organizational characteristics, and customer experience were considered as the independent variables in predicting service mind and skills. The data collected in this study was gathered through questionnaire survey with 291 employees in five hospitals - from Sept. 10 to Oct. 16 in 2004. The results are as follows. 1. The regression analysis showed that job satisfaction and service commitment of organization were statistically significant in predicting service mind and skills. 2. The hierarchical regression analysis showed that the effect of hospital type on service mind was explained by service commitment of organization.

The present report aims to examine the assistive technology(AT) service operating system for the Disabled in Sweden, and will give it to NHIS(National Health Insurance Service) to manage of policy for AT service operating system. The user of AT is around 10% of the Disabled in Sweden which is introduced the AT service system to support the independence for the Disabled. To provide AT service, the role of the Ministry of Health(planning and regulation, controling Handisam and Hi as a subsidiary), County councils(providing and follow up medical AT service, operating AT service center) and Municipalities(providing general AT service) in Sweden is decentralized strictly. Specially, all the AT device is lent freely and recycled suitably for persons with Disabilities, moreover nurses, physical therapist and occupational therapist has a qualification for prescription of AT device . This finding will be the basis to improve Assistive Technology Operating System in Korea.

Recently, new financial services related to FinTech has gained attention more and more. Online P2P financial services transactions such as FinTech require careful examination of the constituents of information systems as an investment is made based on the information presented on the online platform without direct face-to-face contact. The purpose of this study is to find out the success factors of online P2P Lending service among FinTech. To serve the purpose, we build IS (information system) success model, and then use Kano model and fuzzy analytic hierarchy process (Fuzzy-AHP) to find out factors for the success of online P2P Lending service. In particular, this study uses Kano model to classify information system satisfaction factors and to calculate the satisfaction coefficient. The Kano model, however, has a drawback of evaluating single criterion. Therefore, we use multi-criteria decision-making technique such as Fuzzy-AHP to derive the relative importance of the factors. The analysis results show different results depending on the analysis technique. In the Kano model, most of the information system factors are a one-dimensional quality attribute. The satisfaction coefficient is highest for personalized service, followed by the responsiveness of service, ease of using a system, understanding of information, usefulness of information' reliability. The service reliability is the highest in dissatisfaction coefficient, followed by system security, service responsiveness, system stability, and personalized service. The results of the Fuzzy-AHP analysis shows that the usefulness of information quality, the personalization of service quality, and the security of system quality are the significant factors and the stability of system quality was a secondary factor.

In this paper, We develop performance evaluation model for Twin fork Automated Storage/Retrieval systems. The system is modeled as a modified bulk service queueing system consisting of one exponential server with limited system capacity. The differance between this model and general bulk service queueing model is the inequality of transition service rate of each stage. The ejective of this model is to provide system characteristics for Twin fork AS/R system design problems, which are the number of customers in system, wait time in system and queue, the system queue size.
