As energy-saving techniques based on human behavior patterns have recently become an issue, the occupant-centered control system is adopted for estimating personal preference of indoor environment and optimizing environmental comfort and energy consumption. Accordingly, IoT devices have been used to collect indoor environmental quality (IEQ) data and personal data. However, the need to safely collect and manage data has been emerged due to cybersecurity issues. Therefore, this paper aims to present a framework that can safely transmit occupant-centered data collected from IoT to a private blockchain server using Hyperledger fabric. In the case study, the minimum value product of the mobile application and smartwatch application was developed to evaluate the usability of the proposed blockchain-based occupant-centered data collection framework. The results showed that the proposed framework could collect data safely and hassle-free in the daily life of occupants. In addition, the performance of the blockchain server was evaluated in terms of latency and throughput when ten people in a single office participated in the proposed data collection framework. Future works will further apply the proposed data collection framework to the building management system to automatically collect occupant data and be used in the HVAC system to reduce building energy consumption without security issues.

Recently as return farmers has been increased rapidly, the introduction of a system of rental housing is being considerated in order to induce regional fixation. It was examined organizational management, business scope of rural type rental housing, management role, through the analysis about the management realities of the business of similar form Rural-Fishing New Town project. Jangseonggun and Hwasungun have maneged rental housing 280ho in Rural-Fishing New Town project. It is large village among Rural Rental Housing. And these counties have organized the complex on a large scale among the rental housing. Local governments have managed and operated directly, also these governments have two different methods for the co-management, and the way of making payment. Rental housing management services are divided into rental management, housing management, tenant management. Rental management services such as residents of recruitment, tenants and retreat, rent collection and the storage, management and leasing promotion of the cantilever, surveys of residents. Housing management services such as check of various facilities, maintenance and maintenance work, security and cleaning and daily facility management. Tenant management is life management in connection with housing welfare. In the rural type of rental housing, there are few cases to operate a management office. It is often supplied by rental housing to buy a house or vacant land within the existing village. In this case, by utilizing community facilities within the existing village instead of establishment of extra facilities,It doesn't need to make payment for maintenance fee. In the smaller complex than No. 20, it is self-managed by the tenants in order to reduce the administrative costs and specify the necessary municipal manager. Organization form can be maneged directly from local governments and part of for the management of the building can be employed a mixed management system to delegate management to private organizations such as non-profit organizations or neighborhood association. Tenant management helps people who move in a rental house live on stable circumstance in there area by connection with the program of life support.

플랜트 프로젝트의 배관공사는 플랜트 설비의 중요한 공종(工種)이다. 종래에는 시공 현장에서 작업자가 수백장의 배관스풀 도면과 문서를 가지고 다니면서 설치 확인 내용을 기록하고, 현장사무실에서 기록한 사항을 다시 시스템에 입력 혹은 문서작성을 해야 하기 때문에 중복 업무가 발생하여 배관 공사의 효율성 저하 및 공기지연을 초래한다. 또한, 각각 다른 장소에서 각 다른 작업자가 설치 이력 관리 업무를 수행하기 때문에 통합적인 공정관리를 하려면 전체적인 공기가 많이 소요된다는 문제점이 있다. 따라서 본 논문에서는 배관스풀마다 서로 다른 QR Code를 부착하고 배관공사중에 배관스풀의 이력을 유무선망과 연계하여 QR Code로 통합 관리하는 안드로이드 어플리케이션을 구현하고자 한다.

This paper is part of the dissertation for an MSc in Project Management and Innovation of Strathclyde Business School The research aims at understanding how IT-SMEs (Small and Medium-sized Enterprises in Information Technology Business) implement and use Flexible Work Arrangements and Flexible Working Hours (FWH/FWA) in their organisations. In-depth interview data was collected from managers and business owners of 31 companies whose needs for Work-Life Balance varied. Results show that many factors positively influence IT-SMEs to use FWH/FWA. For example, customers and partners working at different work-hours, traffic congestions between home and office, and the general stereotype of IT personnel. However, the results also found several concerning factors that may hamper the success of FWH/FWA implementation. They include the inadequacy of management skills in tracking, monitoring, and assessing employee's real performance, contextual factors for Thai IT-SMEs, i.e. conflict resolution culture, IT people's protocol of communication exchanges, and shortcoming of technology infrastructure. The findings also show that many companies that had used FWA eventually stopped. Thus, a four-phase cyclical framework called PLIC (Purpose-Limitation-Implementation-Consequence) has been developed as an approach to FWH/FWA implementation.

This study aimed to explore influencing factors on the establishment of the network system between public hospitals and to make a process evaluation of it. we analyzed the case of a strategic alliance contracted by a National University Hospital(NUH) and a Community Hospital(CH). Main points of the project were regular dispatch of clinical specialists in the NUH such as gastroenterologist and running teleradiology program. The NUH considered the improvement of it's image as a public hospital as a successful element of the network program. The provincial office which have to manage the CH satisfied with these program in terms of helping CH in need of clinical specialists. Staffs in the CH pointed out the problem of discontinuity for patients who visited the CH. Three institutes argued that continuous support of central government in the relevant institution and budget could play the most important role in the advance of the network system between public hospitals.

The purpose of this study is to suggest a actual conditions and expert's role on the green tourism in rural community. There are four types of green tourism in rural villages. It is an alternative tourism that has naturalism and sustainability, not mass tourism. I can find it is a one of the new rural development method in a point of view of rural people's income. Green tourism requires a participation of village peoples. So, management hang on not government office, but village people themselves. By surveying green tourism villages in the case of this study, I propose a few results as follow; firstly, green tourism of Korea will give an innovation to stagnant rural society. Secondly, rural people themselves must participate directly in development and guidance, when every programs are advanced. Thirdly, through this project of green tourism, we expect that urban and rural symbiosisically have a network.

Soil loss is a serious problem frequently caused by local torrential rainfalls due to climate change. In particular, soil loss is occurring in agricultural areas rather than urban areas, and many pollutants are introduced into rivers, causing environmental problems. To reduce soil loss, the Ministry of Environment has designated and managed non-point source management areas. The Jaun-district in Hongcheon-gun, which was designed as a non-point pollution source management area in Gangwon-do, is located in the upper stream of Soyang Lake. Most of the agricultural fields are composed of highland agriculture fields. The highland agricultural fields in the Jaun-district are also composed of large-scale farming areas, and the ditches located near the agricultural fields have been illegally used for farmland. Therefore, the local government in Hongcheon-gun is conducting a project to restore the ditches occupied by agricultural fields. However, an analysis of the amount of soil loss that can be reduced by the restoration of the ditches has not been conducted yet. Thus, the purpose of this study was to analyze the effect of reducing the soil loss from the restoration of the ditches used as agricultural fields in the Jaun-district. The SATEEC L Module was used to analyze the reduction in soil loss by ditch restoration. The SATEEC L Module was constructed to estimate the LS factor using Moore and Burch's method after calculating the slope length using the digital elevation model and the maximum allowable slope length. The LS factor and the USLE formula were used to estimate the amount of soil loss that could be reduced by ditch restoration. The analysis showed that the ditch restoration could reduce about 16.6% of the soil loss in the Jaun-district. The results of this study will contribute to the study of methods to reduce soil loss in non-point pollution management areas.
