Recently, foreign utilities emphasize the importance of the value-added services based on Information Technology(IT) as one of the strategic technologies for establishing a new power system in the future digital society. They develop many different types of the value-added services and apply the systems for customer. In domestic case, the data from the Automatic Meter Reading (AMR) System is used only for calculating the tariffs. Data from the AMR system can be strategic assets for utilities to provide the value-added services for customer. Development of the value-added services for utilities and customer needs processing and managing the AMR data. In this paper, the energy consulting service, which is adequate to new power system environment, is suggested for development of the value-added services. The application of the suggested service will bring the effect of reducing the monthly bill for customer. Also the service will give not only the effective demand side management(DSM) and load control, but also reduction of the investment for utilities.

Demand for new information services is ever increasing as information technology advances in an unprecedented pace. Capabilities of information technology to overcome the time and space limitations enables efficient storage and processing of a large volume of data shared by many users in geographically dispersed areas. As the users ask for more useful information services, it is necessary to develop information services tp meet the needs of users. Enhancing information services is also necessary to cope actively with the pressures to open the information service is also necessary to cope actively with the pressures to open the information and telecommunications market as the level of Korean information services industry is still in its infancy. Value Added Network(VAN) services have a tremendous growth potential and its economic and social impact would be great as the information society matures. This study suggests a direction for the development of value added and new-media services based on the survey of individual and business users of information services.

This study was carried out to investigate the development and oviposition characteristics of Protaetia brevitarsis fed mulberry fermented sawdust added with mulberry cake. The results of rearing of P. brevitarsis larvae on oak fermented sawdust and mulberry fermented sawdust added with different ratio of mulberry cake, the development periods of larvae feed sawdust with mulberry cake were about 41.6~48.5 days and shortened by 117 or more than that without treatment. The development periods were shorter as the ratio of mulberry cake added increased and there was no difference according to the kind of sawdust. But the weight of the larvae raised in mulberry fermented sawdust added with mulberry cake was heavier than that of the larvae raised in oak fermented sawdust added with mulberry cake. When mass rearing P. brevitarsis larvae in oak fermented sawdust, the addition of 5% mulberry cake was appropriate. Also, the average number of laying eggs of female who fed diet with mulberry cake was 12.3% higher than that of untreated.

One field that the information society has recently taken much interest in and has continuously implemented is medical services. Health tourism services which emphasize today's patient-oriented management rather than the past hospital-oriented management are highly value-added. As interest in physical fitness increases in keeping with such trends of the society at large as the declining birth rate and increasing life expectancy, and the medical market is opened, the added value of medical services that attract and manage domestic and foreign patients from the global market and satisfy their diverse desires with domestic medical competitiveness such as excellent medical staff and technology is on the spotlight. Hereupon, this study intends to suggest the possibility of developing competitive domestic medical services into a highly value-added industry in keeping with changing environment.

This study is to examine the effects of high commitment HRM on service performance in the service industry, and to examine the mediating effect of the organizational internal innovation direction. Specifically, the direction of internal innovation consists of high-value-added HR and service and cost-reduction downsizing. We assumed that the high-value-added direction of HR and service will have a positive mediating effect. And assumed that cost-reduction downsizing direction has negative mediating effect. The data were collected from 2013 workplace panel survey(WPS) of the Korea Labor Institute(KLI). Among the 1,775 companies, 896 companies classified as wholesale and retail, transportation, professional scientific services, education services, health social services, financial services, and other services (such as information society support services) were extracted and used. In summary, high-commitment HRM has a positively significant effect on the direction of high value-added innovation of HR and services, and has a negatively significant effect on the cost-reduction downsizing direction. In addition, the direction of high value-added innovation of HR and service was positive effect on service performance, and cost-reduction downsizing innovation direction has a negative effect on service performance. And the direct effect of high commitment HRM on service performance has not been confirmed. However, we confirmed the positive mediating effect of high value-added innovation direction of HR and services, and confirmed that the negative mediating effect of cost-reduction downsizing. Therefore, it is confirmed that the two variables have a full mediating effect on the relationship between high commitment HRM and service performance.

In the third generation mobile telecommunication systems such as UMTS, one of the important problems for value-added services is to check the recoverability of costs used by a mobile user. Previous authentication and payment schemes for value-added services by a mobile user across multiple service domains, rely on the concept of the on-line TTP, which serves as the users certification authority. In the third generation systems with many service providers, a wide range of services, and a diverse user population, authentication mechanisms with the on-line TTP provide a far from ideal solution. In this paper we present an efficient public-key protocol for mutual authentication and key exchange designed for value-added services in the third generation mobile telecommunications systems. The proposed ticket based authentication and payment protocol provides an efficient way for VASP to check the recoverability of costs without communication with the on-line TTP Furthermore, the proposed ticket based protocol can provide anonymous service usage for a mobile user.
