The purpose of this study is to introduce ubiquitous home services for the aged. In comparison with general ubiquitous homes, ubiquitous homes for the aged have two major characteristics. First, the service contents should be expanded and strengthened. Second, the services should be customized to each individuals. The primary objective of a ubiquitous home for the aged is health care. The three affordances for this objective are 1)prevention of sickness and reducing the speed of aging process, 2)technical assistance for disability, 3)recovering and enhancing the physical and cognitive function. For this purpose this paper analyses the characteristics of the aged and current ubiquitous technology and ubiquitous home service, thus providing an outline for ubiquitous services necessary for aged people.

As education environment is changing rapidly and competition of education industry is more intensive, the importance of service view about education is increasing as a differential competitive advantage. This study attempted to investigate the impact of service convenience as a different competitive advantage on e-learning acceptance by using TAM. The purpose of this study is to examine how five-dimensional service convenience constructs(decision convenience, access convenience, transaction convenience, benefit convenience, post-benefit convenience) affect consumers' perceived usefulness, attitude and usage intention. For this study, data were gathered from respondents who bought or used e-learning services and analyzed by structural equation model. Among the five-dimensional service convenience constructs, two constructs(benefit convenience, post-benefit convenience) affected consumers' positive perceived usefulness, attitude and usage intention about e-learning service. The results show that management and investment to improve benefit and post-benefit service convenience make consumers' positive attitude and usage intention about e-learning service.

Since Amazon announced plans to deliver goods to customers using drones, many countries and companies have become interested in drone logistics delivery services and have begun testing drone delivery for various goods based on service scenarios. Whenever there is news of a successful drone delivery anywhere in the world, people increasingly expect the delivery of goods through drones. Although delivery services using drones are currently in a trial-and-error stage, given technical limitations and institutional and social constraints, a complete shift to drone logistics delivery is not yet possible. In anticipation of the drone logistics delivery service, recent drone delivery tests, current service trends, and requirements for drone delivery service will be examined.

Artificial intelligence-based services are expanding into a new industrial revolution. There is artificial intelligence technology applied in real life due to the development of big data and deep learning related technology. And data analysis and intelligent assistant services that integrate information from various fields have also been commercialized. Chatbot with interactive artificial intelligence provide shopping, news or information. Chatbot service, which has begun to be adopted by some public institutions, is now just a first step in the steps. This study summarizes the services and technical analysis of chatbot. and the direction of public administration service chatbot was presented.

Recently, the need for LBS (Location Based Services) is increasing with the rapid growth of the location measurement units, mobile devices, and communication technologies. Especially, wireless carriers are concentrating on LBS since it is regarded as so-called 'killer application' among wireless data services. Although LBS give us convenience and useful information, its use also raises privacy issues. There are quite possibilities that the people's locations are tracked by location measurement units while people do not recognize the existence of the units. To protect a person's location information, lawful and technical aspects should be considered. In this paper, we explain issues, regulations, standards, and platforms related to the protection of the location information. Finally, we suggest the architecture of a platform complying with the regulations and standards. It considers various issues not covered in other studies.

This paper develops a model of customer satisfaction in the mobile telecommunication services. We examine the relationships among customers'overall satisfaction and underlying dimensions； perceived service quality, service value, and brand image. Variables related to customer satisfaction and dissatisfaction are derived from customer critical incidence survey. The model is estimated with multi-variate data analysis. Results indicate that the (1) technical service quality is the main driver of customer overall satisfaction, (2) some peripheral services are rapidly evolving into the core services of mobile telecommunications, and (3) the current policy of service providers does not focus on customer satisfaction but on establishing churning barrier by increasing switching costs.

Objectives: The purpose of this study was to identify resources put into clinical. activities and identify a new RBRVS for oriental medical services in the Korean National Health Insurance. Methods: Based on a survey of physician's time, physical effort & technical skill, mental effort & judgment, and stress that were used for patient treatments, relative input values for the relevant clinical activities were estimated and rearranged in a way to be compared. with the current values in health insurance. Results: We found the actual resource-based relative values for oriental medical services statistically different from the current values, with a narrower variation in value distribution. Conclusions: The findings suggest the C\lrrent RBRVS should be revised to reflect the actual input resources into physicians activities and to avoid a distortion of physicians behavior.

Special Libraries are not the organizations established and administered by the Library and Reading Promotion Law, but the ones organized to provide necessary knowledge and information required in the works performed by the staff of organizations. The goal of special libraries is to provide the information and materials required by the parent organizations, preferably, at the right time and in the right form. In accordance with the specialization of social structure, the number of special library has been increasing. Especially, industries need industrial information in their introduction of new management techniques and in the processes of technical development, so special libraries attached to industries have remarkably been increased. Special libraries, along with academic libraries, are the organizations providing necessary materials for the specialists who are producing knowledge of every field in the society. However, apart from academic libraries, the organizations, manpower, works, collections and services of special libraries have not been properly investigated and known. This research has tried to identify if those factors are provided for propose services. The result shows which factors are fulfilled enough or which ones need enforcement.

The recent cyber attacks paralyzed several major banking services, broadcasters, and affected the services of a telecommunications provider. Media outlets classified the attack as cyber terror and named it an Advanced Persistant Threat. Although the attack significantly disrupted these services for at least one day, various components used in the attack were not new. Previous major cyber attacks towards targets in South Korea employed more advanced techniques thus causing greater damage. This paper studies the anatomy of the recent 2013.3.20 attack, studies the technical sophistication of the malware and attack vectors used compared with previous attacks.
