  • Construction project is completed through several stages and problems of each stage affect directly not only now but also next. Defect of 2D drawings influence in construction phase, and it make many loss on project. Nowadays we practically use real Mock-up test in construction sites to solve the problems. But it also has many problems which are waste much money and time. Therefore, this study tries to analyze effect that is occurred by appling BIM Mock-up simulation instead of real Mock-up execution. These analysis is conducted by comparing two construction building site. These have same shape but one is made for BIM Mock-up, and another is real Mock-up. Comparison points of view are cost, time and operator's satisfaction. It is expect that BIM Mock-up is more effective at low cost and on shorter time. But our analysis show that each are conducted different part of function. So new Mock-up type is required. Hybrid Mock-up is combine real mock-up with BIM simulation and it can minimize risk of project.

  • Curtain wall (for the outside wall) must be designed and constructed to resist weather condition of nature like rain. wind and surrounding environment. So, Now days, Mock-up test of curtain wall's total capability is generally used for skycraft building. But, Mock-up test specification in korea is so weak that there are lots of disputation. Also, lacking of clearness in specification causes many trouble in adaptation. Therefore, I would like to consider the problem of Mock-up test specification by inspecting and comparing with other country's works. and I will mention the way of approvement in our specification.

  • 하나로를 이용한 재료조사시험용 계장캡슐 개발에 앞서 캡슐 mock-up (96M-01K)을 제작하였으며, 이 캡슐 mock-up의 실제 하나로 조사시험공 장입시를 가정하여 강도 및 열적 건전성 평가를 수행하였다. 평가 결과 하나로 정상출력시 (30MW) 캡슐 mock-up 내 조사시료의 온도는 진공 및 heating system을 사용하여 279~473$^{\circ}C$ 범위로 조절될 수 있었으며, 목표 조사기간 동안 캡슐 mock-up은 강도적으로 허용기준을 충분히 만족함으로써 안전한 것으로 판명되었다. 향후 본 캡슐 mock-up을 이용한 노외 simulation 실험 등을 통하여 기존 캡슐 mock-up의 건전성을 확인한 후 이를 기준으로 하여 표준형 하나로 캡슐을 설계 .제작하고자 한다.

  • An experimental study was carried out with the Mock-up made for the improved water level control of the steam generator in nuclear power plant and for the confirmation of swell/shrink status of the water level by opening and closing the steam dump valve. We can confirmed the possibility of using the Mock-up by introducing the PI controller and the FUZZY controller. Accordingly, we can confirmed that the practical usability of advanced controllers, which will be developed for the improved water level control of the steam generator in nuclear power plant by using the Mock-up.

  • This study aims to know temperature and humidity handling ability of Hwang-To brick and traditional paper window's in mock-up room test. To achieve these goals, mock-up room test was carried out. The results are as follows. 1) There are no significant differences among specimen in temperature handling capacity. 2) Traditional paper windows are very sensitive when compared with glass window in humidity control. 3) Traditional paper windows have a big handling capacity in humidity control when vapors letting out in mock-up room. 4) Hwang-To brick case is more stable than other cases in relative humidity variances because it has more potential to contain humidity.

  • For Mega foundation, concrete must have high strength and high flowability. Especially in marine environment, concrete durability becomes a significant property. In this study, high durable concrete, under marine environment, was developed. And to estimate its performance, the world's biggest Mock Up test, $4m{\times}4m{\times}4m$ size, was performed.

  • This paper describes research results for the measurement and analysis method of magnetic signatures generated from the ship's magnetic mock-up model. In this paper, we present the theoretical and experimental techniques for the separation of the permanent and the induced magnetic field from the measured magnetic signature of the mock-up model. Also, we describe the prediction method of the induced magnetic field generated from mock-up model using the Magnet s/w, one of the FEM analysis tools for the electro-magnetic field and the magnetic dipole modelling method based on the least square techniques. The proposed modelling and analysis methods can be used for the prediction and the analysis of the static magnetic field generated from the real naval ship as well as the mock-up model.

  • The mask-face interface design should consider the face shape to improve the half mask respirator's fit ratio. This study tried to design the mask-face interface using recent Korean face data. By using the data of 1536 men's 3D face scanning (Size Korea data), head clay mock-up was made and mask-face interface line was extracted from this head mock-up. Using this interface line, the half-mask prototype was made. According to the quantitative fitting test, the proposed mask was found to be well fitted (average fit-ratio > 100). The proposed method had two advantages. 1) The method could use massive head-related anthropometric data like Size Korea data. 2) The qualitative fit test (observation) could be conducted very quickly by fitting the prototype to the head mock-up. However, this method also had several limitations. 1) The head clay mock-up could be different according to the mock-up maker. 2) The average values of the head-related anthropometric data were used to make the head mock-up. Small and large size head mock-ups should be made and tested.

  • This paper presents the result of a mock-up test and field application of concrete that is black in color thanks to the application of superplasticizer containing carbon amino silica black (CASB-SP). Mock-up specimen with a size of $3000{\times}1500{\times}40$ mm was fabricated with black concrete applying 0.5% of CSAB-SP with 27 MPa. After dividing the zone in wall mock-up specimen, three different water repelling agents were applied to verify its effect of efflorescence prevention. It was found that the use of CASB-SP with 0.5% made the black concrete develop a highly clear black color, and the epoxy type water repelling agent had better performance in efflorescence prevention. Based on mock-up test, field application was conducted with bridge member. It was also found that the application of CASB-SP showed favorable results in black color development.
