산업이 발전해 가며 공장 자동화를 하는 회사는 나날이 늘어가고 있으며 현재 산업 전반에 걸쳐 자동화 시스템을 채택하지 않는 곳을 찾아보기 어렵고 이 시스템의 시험 및 운영자 교육용으로 시뮬레이터에 대한 관심은 높아 가고 있는 실정이다. 여기에서는 한국전력에서 사용하고 있는 터빈 제어 삼중화 시스템이 어떠한 보팅 기법들을 적용하여 설계되었으며 그 기능이 어떻게 구현되었는지를 실제 제품의 사례분석을 통해 검토해 보고자 한다. 검토 대상은 삼중화 제어기에 대해서만 시행할 예정이다. 이는 실제 현장이 경제성을 수반한 제어기의 신뢰, 이용, 안정, 수행, 지속, 시험, 확실성 등을 원하고 있으며 또한 시뮬레이터를 설계하는 사람들에게 삼중화 주제어기에 대한 비교(MARK-V, Triconex-TMR, GE-Fanuc, Woodward-Micronet) 소개함으로서 더욱더 현장과 가까운 시뮬레이터를 설계할 수 있도록 하기 위함이다.

Electronic detonators are widely used in various construction sites due to accurate delay time. Including the cases with exceeded noise and vibration from site using electric/non-electric detonator, electronic detonators are used to improve blast fragmentation or to reduce the cost of secondary partial blasting. Furthermore, the number of cases using electronic detonators are increased for reduction of the cost and construction period by maximizing operations efficiency. This case study is about applying electronic detonators on large section station, tunnel construction site which is the part of urban area GTX A project. Although it was initially planned to utilize non-electric detonators, damage was inflicted on safety-thing. We have considered blasting method using electronic detonators as solution of this problem. By applying electronic detonators, we not only satisfied environmental regulations but also prevented nearby safety-thing from getting damaged. In addition, we were able to shorten the construction period than the initial plan by conducting single simultaneous blasting on large section station, in order to ensure safe and efficient construction.

Effectiveness of Just in time managing system can be obtained by removing unexpected lead-time and maintaining consistency on the physical transportation of construction resource. Construction resource management is essential on checking on load data from production of shop to field, and it is based on building resource life cycle information. In this study, production, transportation, and assembly disciplines of concrete construction should real time communications exchanging information related to shop-field with each other, Establishing information support system is an important initial step for promoting active cooperations among these resource life cycle on data flow. To achieve this, on suitable using management point, we suggest a concrete construction control model.

This study is about the case applied of a shallow foundation reinforcement method for a low/mid-rise building where a relatively small load is applied by using a soil stabilized material that utilizes recycled resources. First, laboratory mixing test was conducted for four mixing ratios in order to derive the optimal mixing ratio in the field. Using the derived optimal mixing ratio, it was applied as a shallow foundation for the building in the field. The field application method used a simple process of compaction by the soil mixedure with the original soil and the soil stabilized material in the field. After field application, a plate bearing test was performed on one original ground and two improved ground to confirm the allowable bearing capacity. As a result of checking the bearing capacity, it was found that sufficient bearing capacity was exhibited.Therefore, it was confirmed that it can be used as a shallow foundation for the building.
