The tourism motivations of the senior tourists were used to analyze the effect on the tourism satisfaction. As result of the analysis, the rest motivation and knowledge expansion motivation bring positive effect except the social connectedness motivation. The senior tourist wanted to have their own time and preferred the tourism program focused on the leisure. They also seemed to have comparably high self-esteem. The self-development programs should be made and good relationship through the tourism satisfaction must be developed. The result of the study shows that the senior tourists are exhausted mentally and physically, and this fact affected a lot on the rest motivation which is one of the tourism motivations.

In this study, the electrokinetic remediation test for the kaolin contaminated by lead was performed and voltage, zeta potential, pH distribution, current, contamination transport in soil sample were studied and finite differential numerical analysis program(HERP) for a contaminated soil were compared with those of test. From the result of HERP, in the anode it was represented that the rest concentration was decreased with the voltage. Hence, if treatment time was continued for a long in the constant voltage, comparing with sample having no change in the rest concentration, it is considered that the voltage gradient is the control factor of the rest concentration.

German working hour law of 1994(Arbeitszeitgesetz) provides maximum working hour as 8 hours a day and 48 hours per week. The law provides that minimum 11 hours rest-time is required between the end of a day's work and the beginning of the next day's work. Namely, the hour that the workers are put under commanding of the user is restricted within 13 hours per day. In the meantime, article 5, 7, 14, and 15 of the law have some letting the exceptional provisions regarding the working hour and rest-time of flight crew, and 2nd administrative order for the aviation transportation business owner, which is established based on such exceptional provisions(2.DV LuftBO), provides the working hour and rest-time of flight crew quite in detail. The administrative order is detailed quite regarding block time, flight working hour, and rest-time. So, it does not need to interpret additionally. Airlines in Korea should observe the both Labor Standard Act applying to general workers and Aviation Act focused on flight crew, so it is difficult that airlines manages working hour and rest-time of the flight crew efficiently. Therefore, it is desirable that our country refers to and considers adopting this legislation method of Germany which regulates working hour and rest-time of flight crew in detail in the 2.DV LuftBO.

Recently, various studies have been attempted to provide a biological information monitoring service through integrating with the web service. The medical information transmission standard ISO/IEEE 11073 PHD defines the optimized exchange protocol ISO/IEEE 11073-20601 based on the No-IP to exchange the biometric information between the ISO/IEEE 11073 agent and the manager. It's system structure based on the No-IP using ISO/IEEE 11073-20601 is not suitable for providing a remote biological information monitoring services. That is because it is difficult to provide to control and manage the biological information measurement devices, which have installed IP protocol stack at the remote. Furthermore, ACSE and CMDISE in ISO/IEEE 11073-20601 are not suitable to provide U-healthcare services based on IoT because they are complicated and difficult to implement it caused by the structural complexity. In order to solve the problems, in this paper, we propose the biological information monitoring architecture based on ISO/IEEE 11073 DIM/REST of IoT environment to provide the biological information monitoring service based on IoT. To do this, we designed biological information monitoring system architecture based on IoT and the message exchange protocol of ISO/IEEE 11073 DIM/REST between the ISO/IEEE 11073 agent and the ISO/IEEE 11073 manager. In order to verify the realistic possibility of the proposed system architecture, we developed the service prototype.

This study analyzes the risks of explosions of small LPG storage tanks installed at highway rest areas. For this purpose, the ranges of the effect of thermal radiation and overpressure caused by the BLEVE(Boiling Liquid Expansion Vapor Explosion)and VCE(Vapor Cloud Explosion) of a 2900-kg small LPG storage tank installed at highway rest areas were quantitatively evaluated by applying the Areal Location of Hazardous Atmospheres program. The ranges of influence of the derived explosion overpressure and thermal radiation were found to have a maximum radii of 336 m and 423 m, respectively. The study determined that those within 269 m could be severely injured by an explosion overpressure of 3.5 psi, and fatalities from thermal radiation of 10 kw/m² could occur within 192 m of the exploded storage tank. The safety management plan for the LPG storage tank was discussed while considering the auxiliary facilities of highway rest areas and the extent of the damage impact. These research results will help improve safety accident prevention regulations considering the environment and facilities of the rest areas as well as the safety management of small LPG storage tanks installed at highway rest areas.

최근 인터넷의 발달과 함께 웹을 기반으로 하는 클라이언트-서버 분산 구조의 웹서비스 시스템 구조가 점차 확산되고 있다. 게다가, 최근에는 스마트폰을 이용한 스마트폰 애플리케이션이 대중화 되면서, 웹 서비스의 활용이 점차 확대되는 추세이다. 웹을 기반으로 클라이언트와 서버 사이에 통신을 하기 위해서는 원격 프로시저를 정의한 인터페이스가 규정되어야 하며, 기존에는 W3C에서 정의한 WSDL를 사용하여 웹서비스를 기술하곤 하였다. 그러나, 이와 같은 기존의 웹서비스 기술 및 사용방법은 그 구성이 복잡하고 오버헤드가 큰 이유로 널리 활용되지 못하였다. 최근에는 스마트폰이 대중화 되면서 REST 웹서비스의 활용이 확산되는 추세다. SOAP 기반 웹서비스에 대해서는 서비스 조합에 대해서 충분히 다루어 졌으며, 어느정도 정리된 연구분야이다. SOAP 웹서비스는 기계가 인식하기 쉽도록 엄격한 규약과 인터페이스를 정의한 것이기 때문이다. 반면, REST 웹서비스는 최근 이기종(heterogeneous) 시스템 통합 및 스마트폰에서 서버 측 데이터를 접근하는 가장 유리하고 편리한 방법이다. 따라서, 그 활용방법에 대하여 많은 수요가 발생하고 있으나, 일반적으로 잘 소개되어 있지 않으므로 본 논문에서 REST Web Service Open API의 스마트폰 애플리케이션 개발의 활용방법을 소개한다.
