This study introduces trends on silver care implemented with the fourth industrial revolution technology, and discusses the use of digital technology for elderly health and rehabilitation by reviewing relevant literature to examine and present directions for future digital-based silver care commercialization. First, health smart home, which is a smart residential service available through digital technology or IT technology that supports independent living in your home, is available. Second, there are technical services using artificial intelligence(AI) and robots. Robots based on advanced intelligence can serve as an assistant for the health and rehabilitation of senior citizens by supporting services that enable the daily lives of senior, checking their health conditions, and high-quality medical care. For the commercialization of these silver care systems, information and services appropriate to the current situation, such as the physical ability and health status of the elderly, should be provided, and it would be desirable to gradually expand the use of essential technology to reflect the needs of the elderly in use so that the digital alienated.

This study aimed to develop an operating manual on the voluntary activity to the library services with disabled people in the public libraries. Various domestic and overseas manuals on the voluntary activity to the library services with disabled people were analyzed. From the survey and expert interviews, five types of most frequently asked library services with disabled people, face-to-face reading, word input services, services to off-library users, mobility aids services and assistance of engineering devices were extraced. Five specific areas on the voluntary activity were chosen in terms of activity area, barrier type, specific activity field, activity purpose and checklist. Finally, contents of the operating manual was applied to the area of face-to-face reading.

This study aims to analyse the ripple effect of Physical distribution service industry on national economy using input-output tables and present the results as data for political plans in this field. For the analysis, it uses input-output tables developed and published by Sank of Korea in 1998, 2000, and 2003. To sum up the results, production inducement effects are 1757 for railroad transport, 1688 for road transport and 1617 for loading. Import inducement effects of assistant services, loading, storage, warehouse and other transport-related services are low while the effects of water and air transport are high as follows: 0.679 and 0.558 respectively. Then, added-value inducement effects are presented as follows: 0.841 for railway transport, 0.828 for road transport, 0.962 for transport assistant service, 0.939 for loading, 0.938 for storage and warehouse, and 0.942 for other transport-related services. Sensitivity dispersion index of road transport is high while that of water transport, storage and warehouse is low. And influence coefficient of railway and road transport is high while that of water and air transport is low. In respect to the employment structure of Physical distribution service industry, 744,000 are employed for road transport industry, which is the largest number, 19,000 for air transport and 20,000 for assistant services, which is the least number.

This study is about current operating system and development process of remote island route. 14 companies are providing safe transportation service for remote island residents with total 30 boots on 27 routes. Each route transit analysis shows that the number of passenger tends to increase every year. In order to enhance customer satisfaction, more constructive improvement is demanded, such as implementing operation evaluation on each charter service provider.1he result obtained from this study is to be utilized as basic document for remote island route development process in semi-long run basis.

A range of problems have risen as the results of the obligated charter service. Constant lack of operation improvement compared to regular routes and lower quality service are results of business practice by the service providers. Therefore, this study executed an empirical research using AHP to present a method for improvement by investigating remote island charter service providers. Result shows that the desirable method is to implement operation evaluation system to induce service providers to consistently put efforts on the operating system development.

VoIP(Voice over IP)는 저렴한 비용과 다양한 응용서비스 기능으로 기존의 전화서비스를 보조 또는 대체할 서비스로 인식되고 있다. 특히 SIP(Session Initiation Protocol)는 텍스트 기반으로 다양한 애플리케이션과 쉽게 연동될 수 있다는 장점 때문에 차세대 VoIP프로토콜로 급성장하고 있으며 이를 이용한 VoIP 망 구성 및 부가서비스에 대한 관심이 증대되고 있다. 부가서비스는 콜의 발생 여부에 따라 사용자의 콜을 처리하여 서비스를 제공하는 형태와 서버가 직접 콜을 발생시켜 서비스를 제공하는 형태의 두 가지 유형으로 나눌 수 있다. 현재 SIP기반 VoIP에서는 사용자의 콜을 처리하는 서비스를 위한 CPL(Call Processing Language)이 표준화 중이며 이를 기반으로 여러 서비스도 구현되어 있다. 그러나 특정시간에 콜을 발생시켜 사용자에게 서비스를 제공하는 형태의 서비스는 논의되지 않고 있으며 구현된 사례도 아직 없는 상황이다. 따라서 본 논문에서는 이러한 유형의 새로운 서비스의 하나로 예약통화 시스템을 제안한다. 예약통화 시스템은 예약된 시간에 콜을 발생시켜 두 사용자간의 통화를 연결해 주는 예약 시간 기반의 서비스를 개발하는데 이용될 수 있다.

This study was aimed to examine effects of the assistive technology program that has purpose to maintain and promote employment of persons with disabilities. An administrative data constructed by the Korea Employment Agency for the Disabled(KEAD) was utilized. Propensity score matching were used as analysis methods to minish sample selection bias caused by nonrandom sampling. As a result, turnover rate of people with disabilities who used assistive technology device was lower compared to persons with disabilities did not use assistive technology device. Also, in terms of company, for employment promotion effect on the persons with disabilities, company that provided assistive technology device was higher than that of company did not provide assistive technology device. Finally, assistive technology devices were effective in the employment area was confirmed.
