Current improvements on the standard of living reduced working hours and increased leisure time. Therefore, people's ideas on life style changed and different demands on residential environment are being made. Residents of apartment want a community facility that enables constant exchange with other residents and supports living. Ideas on how to use physical space to strengthen a community is becoming an issue these days. Community facility plays a crucial role in giving a certain characteristic to the whole apartment and improving the image as a community. It also provides a physical environment and induces active participation of community life from apartment residents. The community facility in an important environment for children, which helps them develop in growth and in society as well. Community facility is a space where children fulfill their curiosity and amusement. Since children are greatly influenced by the physical surroundings, community facility for children should not remain as a space for fun but should change into a space for interaction. This study chose six apartments at Dongtan New Town, located in Hwaseong, Kyunggido. This study focuses on the characteristics of design for children's community facility and would like to make a proposal about future space planning for children's community facility.

The introduction of BIM technology is expanding not only in the field of design and construction, but also in the maintenance and use stage. In particular, researchers are looking to build a smart facility management system that integrates advanced IT technology and BIM. This study proposes the parts to be used and added to the BIM information, focusing on information generated and exchanged in the application case that is an issue during the current facility maintenance work by introducing the smart facility management technology and its use cases. The effectiveness of this proposal is compared with the scenario in which BIM-based facility safety management is applied and the current business scenario. In conclusion, the requirements for smart facility management are analyzed, and linkable parts between facility management tasks and BIM data that should be reflected in the facility management system are presented. In the maintenance phase, through the use case scenario, the facility management phase is subdivided according to the characteristics and contents of the work. In addition, information about the facilities required for each task is specified. Furthermore, it is examined whether BIM data and IT information can be linked with existing facility management systems. It is a process and guideline that can be provided to practitioners who want to introduce BIM and smart technology to facility management. It can define the required data items and levels according to the required information step by step based on the maintenance case.

현재 일반경비산업은 인적자원에 대한 의존도가 높고, 고객과의 접촉 빈도가 높은 직업이어서 무엇보다도 종사자의 직무수행능력을 통한 만족도가 경영성과에 큰 영향을 미친다고 할 수 있다. 그러나 국내 일반경비산업에서 이와 같이 전문교육을 받은 고급인력이 중요시 되고 있음에도 불구하고 일반경비원의 교육과 직무만족에 대한 연구는 사실상 미비한 실정이다. 따라서, 본 연구는 현직에 있는 시설경비원을 대상으로 신임 교육이 직무만족에 미치는 영향을 규명하고자 탐색적 연구를 실시하였다. 일반경비원 신임 교육이 직무만족에 미치는 영향을 보면 다음과 같다. 첫째, 사회인구학적 특성에 따른 개인적 특성, 교육훈련특성, 업무환경, 직무만족의 차이를 검증한 결과 부분적으로 유의한 차이가 있는 것으로 나타났다. 둘째, 개인적 특성인 학습기대, 자기효능성 중에서 학습기대만이 직무만족에 통계적으로 유의미한 정(+)적 영향을 미친 것으로 나타났다. 셋째, 교육훈련특성인 강사의 자질, 교육시설, 교육내용 중에서 교육시설과 교육내용만이 직무만족에 통계적으로 유의미한 정(+)적 영향을 미친 것으로 나타났다. 넷째, 업무환경(상사의 지원, 지속적 학습문화)은 직무만족에 통계적으로 유의미한 정(+) 적 영향을 미친 것으로 나타났다.

KARI is achieving the KSLV program according to National Space Technology Development Program. In this paper, the authors are intended to introduce the Integrated Power Plant (abb. IPP) test facility which will be constructed for the variety of tests on KSLV program. IPP test facility refers to comprehensive testing equipment for liquid rocket launch vehicle. Using this facility, KARl can verify the adaptiveness of parts and subsystems for launch vehicle and finally can qualify the system characteristics of launch vehicle doing kinds of test including hot firing test. Using this facility, KARI can simulate the vehicle launching circumstances and it make to predict the performance of launch vehicle when its flight test.

This paper proposes the circuit of the simple synthetic testing facility using LC resonance circuit. The analyzed results of the circuit which can be useful for the design stage of the testing facility are also shown. EMTP has been used to analyze the circuit. Two cases of short-circuit test results obtained from the simple synthetic testing facility in KERI are shown with the waveforms of current and voltage. The results also indicate that the simple synthetic testing facility using LC resonance circuit can be easily designed and used very usefully for the research and development for the switchgears.

To build environmentally friendly highways, we testes suitability for unique characteristics of pollution mitigation facility around the highways by evaluating optimal selections and implementation methodologies to minimize loan of non-point pollution substances into water-ways. To do this we categorized EIA target highways into three types ; big drainage basin, small drainage basin, and bridge section as to minimize non-point pollution of highway runoff. The terms of selected facility test based on the Natural and Manufactured Treatment Device were removal efficiency of TSS, BOD, COD, T-N, T-P, compatibility of site selection, economic feasibility, maintenance convenience, and the final mitigation facility.

A making a decision of construction cost has important meaning and function for both contractor and owner in construction projects. Especially, it should be premised that estimating the construction cost in efficient and rational way in public construction, which is invested by government funds, for efficient execution of the budget and investment as a side of government. The systematic methodology for estimating construction cost approximately of a river facility construction project has not yet been established because of its unique characteristics including its relatively small project size in terms of cost. On this study, It collect and analyze a river facility construction historical cost data for develop an approximate cost estimating model for river applied by typical embankment section method and rate application of the others activity type. And it verify suitability of model through a that result of application of real river facility construction statement at developed model. By this study, it is expected to reasonable and systematic estimating construction cost through application of developed model.

Objectives: Using atmospheric dispersion representative models (AERMOD and CALPUFF), the emissions characteristics of each model were compared and analyzed in ready-mixed concrete manufacturing facilities that generate a large amount of particulate matter (PM-10, PM-2.5). Methods: The target facilities were the ready-mixed concrete manufacturing facilities (Siheung RMC, Goyang RMC, Ganggin RMC) and modeling for each facility was performed by dividing it into construction and operation times. The predicted points for each target facility were selected as 8-12ea (Siheung RMC 10, Goyang RMC 8, and Gangjin RMC 12ea) based on an area within a two-kilometer radius of each project district. The terrain input data was SRTM-3 (January-December 2019). The meteorological input data was divided into surface weather and upper layer weather data, and weather data near the same facility as the target facility was used. The predicted results were presented as a 24-hour average concentration and an annual average concentration. Results: First, overall, CALPUFF showed a tendency to predict higher concentrations than AERMOD. Second, there was almost no difference in the concentration between the two models in non-complex terrain such as in mountainous areas, but in complex terrain, CALPUFF predicted higher concentrations than AERMOD. This is believed to be because CALPUFF better reflected topographic characteristics. Third, both CALPUFF and AERMOD predicted lower concentrations during operation (85.2-99.7%) than during construction, and annual average concentrations (76.4-99.9%) lower than those at 24 hours. Fourth, in the ready-mixed concrete manufacturing facility, PM-10 concentration (about 40 ㎍/m³) was predicted to be higher than PM-2.5 (about 24 ㎍/m³). Conclusions: In complex terrain such as mountainous areas, CALPUFF predicted higher concentrations than AERMOD, which is thought to be because CALPUFF better reflected topographic characteristics. In the future, it is recommended that CALPUFF be used in complex terrain and AERMOD be used in other areas to save modeling time. In a ready-mixed concrete facility, PM-10, which has a relatively large particle size, is generated more than PM-2.5 due to the raw materials used and manufacturing characteristics.
