The smart tourism service provides services such as travel planning and tour guides to tourists using key technologies of the 4th industrial revolution, such as the Internet of Things, communication infrastructure, big data, artificial intelligence, AR/VR, and drones. We are developing smart tourism services such as recommended travel products, my travel itinerary, tourism information, and chatbots for tourists through the smart tourism app. In this paper, we develop a smart tourism service system that provides real-time location-based tourism information and weather information to tourists. The smart tourism service system consists of a smart tourism app, a smart tourism information system, and an IoT data collection device. The smart tourism information system receives weather information from the IoT data collection device installed in the tourist destination. The location-based smart tourism service is provided as a smart tourism app in the smart tourism information system according to the Beacon's UUID in the IoT data collection device. The smart tourism information system stores the Beacon's UUIDs received from tourists and provides a safe hiking service for tourists.

The school food service system has been an important national policy in Korea. To find out the reference data of the school food service system, we surveyed four primary schools, one middle school, and one food service center in Nara, Japan. The results are as follows; 1. The school food service was carried out in 99.4% of primary school children and in 82.5% of middle school students. 2. The central commissary school food service system was utilized at 49.0% of primary schools and 68.5% of middle schools. 3. The expense of the system is supported partially by the student's parents and partially by the government, of which the support rate was noticed by the law of school food service. 4. The dietary content of school food service was laid down by 'The rule of the operation basis of school food service'. The menu was chosen by the 7 kinds of stepwise meetings. 5. The teachers emphasized on the food etiquette, the appreciation to the food and the personal relationship during meal, as well as on the nutritional balance. 6. We found other problems in Japanese food service system, such as the sanitary problems, the problems of the new tableware, and whether the central kitchen had less advantage than the individual school kitchen. We can conclude that the school food service system is becoming the essential part in school education, and hope to design not only economical but also educational system in Korea, with the consideration of Japanese system.

건강의 질을 높이고 효율적인 건강전달체계를 마련하기 위해서, 전자건강기록시스템은 건강서비스를 제공하는 의료기관에서 중요하다. 그러나 국내 의료기관에서 현재 운용되는 시스템은 데이터 검색 및 처리를 위해서 분산 환경의 독립적인 소프트웨어 인터페이스를 사용하고 있다. 이로 인해, 새로운 시스템과의 연계시 각각의 인터페이스 모듈을 구입하거나 개발하는데 추가적인 비용 및 복잡성이 증가되고 있다. 이러한 문제를 해결하기 위해서 본 연구에서는 가정간호서비스를 서비스지향아키텍처기반으로 구현 한 후 평가를 수행하였다. 서비스 시나리오를 근간으로 프로세스 모델링과 비즈니스 요구사항을 정의하였으며, 서비스 설계를 위해서 다섯 가지의 검증 항목을 기준으로 17개의 후보 서비스를 도출하였다. 최종 서비스 도출을 위해 서비스리트머스테스트(service litmus test) 기법을 사용하여 7개의 서비스를 선정하였다. SOA 기반의 정보시스템은 비즈니스 프로세스 개선으로 환자 대기시간을 단축하는 효과가 있었다. 결론적으로, 병원정보 시스템이 소비자의 다양한 요구사항에 유연하게 대응하기 위해서는 상호운용성, 재사용성, 유지보수 등이 탁월한 SOA 기술적용을 고려하여야 한다.

In Korea, the government has developed SEUMTER, an administration system for building related public service, to facilitate and promote the electronic submission and permission activities. SEUMTER is progressing legality system based on 2D drawing for building administration permission service. However, there are a lot of problems related to legality system owing to complexity of Korea regulation relation and structure, inefficiency of legality system based on 2D drawing, duplication examination of document (soliciting forms for civil affairs) and drawing. Therefore, the purpose of this study is to develop legality system for building administration permission service based on BIM in Korea. To achieve this purpose, the authors have investigated permission procedure and regulation structure that is used in current building administration permission and suggested permission procedure and regulation structure for legality system based on BIM. In addition, the authors have investigated element technologies (for examples, method of structured regulation, BIM model checker, Viewer, etc) for legality system based on BIM. Finally, the authors have suggested strategy and hereafter direction for application of legality system based on BIM.

This paper presents a novel method to design and implement mobile u-health system by defining the essential elements of mobile healthcare services. We choose common service elements for the proposed u-healthcare scheme and design the service platform. Especially we focus on automatic feces or urine sensing u-care scheme to prove the effectiveness of our platform. We construct the system with sensing part with a manikin and a diaper, wireless communication part with feces or urine sensing data, and coordinator system based on the u-health platform defined in this paper. Experimental results show that our scheme is useful in the area of u-care service for the handicapped, the elderly, and patients who can hardly move by themselves. In addition the designed scheme offers a realized u-care scheme with the purpose of advanced developing tools for application or service developers.

전통적인 시스템 차원에서의 신뢰도 분석 모형에서 탈피하여 사용자가 인지하는 서비스 가용도에 대한 필요성이 대두되고 있다. 본 논문에서는 우선 서비스 가용도 모형에 대해 살펴보고 이의 근간을 이루는 UBG에 대하여 논하였다. 그리고 사용자 모델, 시스템 모델 및 서비스 모델을 복합적으로 고려하여 서비스 가용도를 산출하는 시뮬레이션 모델을 제안하였다. 아울러 예제를 통하여 사용자 모델의 UBG와 시스템 모델을 작성하고 이를 토대로 서비스 모델을 정의하는 일련의 과정을 보여 주었다. 그리고 시스템 모델과 UBG의 여러 파라메타들이 서비스 가용도에 미치는 영향에 대해 살펴보았다.

This study aims to comprehensively understand the dynamics between the factors related to service quality, satisfaction and reuse intention. The contents of the study are as follows. First, it draws the limitations of the existing studies by reviewing the literature related to the relationships between service quality, satisfaction and reuse intention. Second, it highlights the characteristics of System Dynamics as a means of overcoming their shortcomings as well as examining the dynamic mechanism of the relevant factors. Third, it explores the feedback loops of the relevant key variables and the feedback structure of the system. Lastly, it concludes with the suggestions and implications of the key research findings. This study is expected to emphasize the importance of the feedback mechanism operating around the service quality, satisfaction, and reuse intention. Further, the causal loop diagram developed can be a basic material for the diverse levels of governments as well as service providers to refer to for improving the service quality of Community Social Service Investment Program.

Through numerous mobile device technology advances, various multimedia contents is moving towards mobile devices from existing personal computer (PC). These paradigm has emerged taking into account these idea, the so-called N-Screen, N-Screen is user-centric service to provide running and sharing on everywhere via advanced smart system in C-P-N-T (Content, Platform, Network, Terminal). Therefore we must provide securing of various contents, openended platform, and user-centric service for efficient N-Screen service. For These characteristic of N-Screen, this paper propose design and implementation of user location-based N-Screen service system. The proposed system realize user location through user's smart phone and offer automatic streaming service to user. And also, we provide web service-based extended N-Screen service. Thus, user can access various device, such as laptop, tablet, and mobile device.

Along with the evolution of wireless internet environment, information services in mobile internet are being explosively increased. However, due to the high expense for the use of those services, it is not easy to collect the devoted customers. In order to overcome the adverse conditions, the service should be supported by a strategic application system which facilitates easier and fast service for customer's information needs than that of traditional on-line internet. In this paper, we investigate the strategy how to provide the information service under the customer satisfaction, and also consider some ways of personalization of information service and information provision in real-time. As a result of the works, we develop a system, MoSA-CRM(Mobile Service Application based on CRM) to support customer-oriented information service. We believe that the MoSA-CRM system can provide some benefits for information providers in mobile e-commerce market such as flexibility in business strategy, systematic customer relationship management, and growth in financial ability.
