New construction for public transport in congested urban areas will involve tunnel construction adjacent to existing building or bridge foundations and services due to the lack of surface space. Therefore, careful assessment of the important underground structure-soil-tunnelling interaction is relatively new, currently only limited information is available. In this study, the authors carried out FE analysis and the laboratory model test using the photogrammetric technique and suggested the influence zones associated with the normalised pile tip settlement during new tunnel construction.

More than 76% of occupational accidents occur in small and medium sized enterprises(SME) employing less than 50 workers, due to the lack of safety and health systems, and carelessness of workers and owners. Timely Technical Guidance(TTG) project of Korea Occupational Safety & Heath Agency(KOSHA) for SME was initiated to analyze and inform accident causes just after accidents occur. Improvement direction of TTG project is suggested through situation and performance analysis on TTG services conducted in 2012. KOSHA provided TTS services on 15,571 SMEs(suffering at least one accident in 2012), through which the working day losses from recurrence resulted in 19.0%p, 14.5%p and 31.3%p decreases in manufacturing, services and construction businesses, respectively.

Due to the development of technology and medical care following the 4th industrial revolution, the medical paradigm is shifting towards patient-centered medical services. Based on the development of smart home technology, the residential environment is changing into a residential space that cares for and heals the lifestyles and the healthcare of families. As lifestyle changes, the concept of supporting smart home care based on the residential environment is making it possible to build a smart home IoT service design with enhanced accessibility and convenience for medical appointments and well-being lifestyle care. This paper is a study on user-centered health care smart home IoT service design suitable for family members based on the health care, beauty care, exercise care, and customized diet care beyond the conventional concept of health care monitoring. Based on the analysis, this paper proposes a personal care coordinate smart home service design in a human-centered wellness clinic care smart home service design environment. Human-centered wellness clinic smart home IoT service design is meaningful in presenting a vision for research on smart home service design that links hospital-linked and care-linked service industries, which should be considered from the smart home construction planning stage.

While science and technology information service portals and heterogeneous databases produced in Korea and other countries are integrated, methods of connecting the unique classification systems applied to each database have been studied. Results of technologists' research, such as, journal articles, patent specifications, and research reports, are organically related to each other. In this case, if the most basic and meaningful classification systems are not connected, it is difficult to achieve interoperability of the information and thus not easy to implement meaningful science technology information services through information convergence. This study aims to address the aforementioned issue by analyzing mapping systems between classification systems in order to design a structure to connect a variety of classification systems used in the academic information database of the Korea Institute of Science and Technology Information, which provides science and technology information portal service. This study also aims to design a mapping system for the classification systems to be applied to actual science and technology information services and information management systems.

Recently, it is easy to find cases of 3D printing product, equipment, and materials in the architecture field. However, there is a lack of distribution environment where 3D printing products can be traded on an online platform or to access on-demand services in the architecture field. Therefore, in this study, a distribution platform development plan was proposed in consideration of the maturity level of the 3D printing distribution market in the domestic architecture field. For this purpose, the research was carried out as follows. First, by analyzing the case of the 3D printing distribution platform, the development stage of the distribution platform was set as three stages from the perspective of market maturity, platform development level, and sales/purchase experience level of suppliers and consumers. Second, the market maturity of the current domestic architecture field was evaluated as the first stage, and a distribution platform that could be implemented in the first stage was presented as a pilot. Third, we presented the first stage pilot, collected practical opinions on future construction plans through in-depth interviews, and presented detailed implementation plans for each stage necessary to achieve the second and third stage market maturity goals. Based on the roadmap derived from this study, it is expected that the domestic distribution platform market will grow step by step in the future and be utilized for business model development.

The greenhouse control system for educational purpose is designed by personal computer. This system should observe and control the growth conditions for crops in both plastic film and glass greenhouses. In this contribution puts emphasis on construction of greenhouse control system by personal computer under the aim of creating safer, more effective and more economical services. This system is developed for the requirements of the intelligent greenhouse control system and is powered by solar energy. A photovoltaic system with sun tracking module is used for the greenhouse control system.

건설공사 표준품셈 기계경비 부분은 1960년대 초 일본 및 미국의 자료를 근간으로 하여 제정된 이후, 극히 부분적으로만 제 개정되었을 뿐 그 동안의 건설기계와 공법의 발전을 반영하지 못하고 있다. 본 연구에서는 합리적인 기계경비 산출을 위해 불도우저와 로우더를 중심으로 국내 외 문헌조사, 건설현장 16개소 실사, 그리고 건설기계장비 임대업체 20개사를 대상으로 설문조사 및 인터뷰를 실시하였다. 수집한 자료와 현행 표준품셈의 기계경비 산출에 적용되는 수치들을 비교 분석한 결과, 관리비는 금리와 보험료를 고려하여 6종건설기계와 일반기계를 구분하여 현실적인 수치를 제시하였으며; 운전경비는 조수를 삭제하는 것이 현실적인 것으로 나타났다. 또한 주연료 및 잡재료는 현행수준이 적정하지만 장비가격은 상향조정할 필요가 있는 것으로 분석되었다. 논문에서 제시하고 있는 각종 자료 및 수치들은 건설기계와 기술의 급속한 발전을 예정가격산정의 기준에 적용할 수 있는 기초가 될 수 있을 뿐 아니라, 관련 연구의 토대가 될 수 있으리라 기대한다.
