A C-type LNG mock-up tank was constructed to evaluate the durability of the tank and its structural safety. An experimental strain analysis system equipped with strain gages was designed to investigate the structural behavior of the inner tank at a high hydraulic pressure. In addition, the insulation used in the space between the inner tank and outer tank had a compressive strength and the inner tank thickness of the cylindrical shell and hemisphere was 4.0 mm, which was designed to be thinner than the existing rules. The strains on the inner tank were measured with increasing pressure, and these measurements were compared and analyzed at the strain gage attachment points.

본 논문에서는, 이중대역 안테나를 가진, 인체 거치용 단말장치 모사구조의 HAC(보청기 EMC) 지수가 실재환경으로부터 받는 영향에 대한 관찰이 이뤄진다. 첫째, 부착형 이동통신 장치에 필수적인 인접 구조를 고려한 이중대역 내장형 안테나가 설계된다. 이 설계는 모사구조의 제작을 통해 실제의 모습을 갖춘다. 둘째, 이 장치의 HAC 지수는 손에 부착하기 전과 후에 대해 모의시험 및 측정을 통해 얻어진다. 특히, 실재 장치의 전자장 모의시험 결과는 표준 측정법에 의해 타당성이 확인된다. 마지막으로, HAC 기주는 대역, 실장환경, 손(인체) 효과의 관점에서 분석된다.

동절기 콘크리트 공사에서는 무엇보다도 저온환경에서의 콘크리트의 안정적인 품질 확보가 중요하다. 따라서 본 연구에서는 고분말도 발열분체를 적용하여 동절기($0^{\circ}C$이하)에서도 양생 없이 강도발현이 가능한 콘크리트를 개발하였으며, 이를 현장에 적용하기 위해 실 부재 사이즈의 Mock-Up 부재를 제작하여 개발기술의 현장적용 성능평가를 실시하였다.

Mock-up model can be applied to measure accurate performance data but difficult to apply the variables in experiment. There can be a slight experiment errors in Scale model, but various parameters can be applied for a objective experiment. This paper aims to compare the daylighting performance in 1, 1/5, 1/10 scale model of offices and analyze the experiment errors to certificate the influence of model experiment. To analyse daylighting performance, a comparison of a Mock-up model, sized $12.0m(w){\times}7.2m(l){\times}3.7m(h)$, designed for experimentation of daylighting systems and its 1:5, 1:10 scale model. It has an identical configuration of reference room and the test room. For the test room, the lightshelf system was designed as Micro-4 reflective material. To assess work plane illuminance and light factor, photometric sensors of each room were installed at work-plane(6 points) and exterior horizontal illuminance (1 point). And luminance of window, rare of the room was measured under clear sky. It is to be monitored by Agilent data logger, photometric sensor Li-cor and the Radiant Imaging ProMetric 1400. Comparisons with a light factor, increase-decrease ratio and luminance are discussed.

Unit cabin means room, which is installed in the high value-added vessel such as drill ship, offshore platform and FPSO, after pre-assembled. In order to develop the noise control design for a unit cabin, a variety of acoustic tests such as sound absorption, transmission and radiation measurements were carried out by using the deckhouse mock-up. From the tests, it was found out that the sound transmission loss between cabin and corridor was 13 dB below than FPSO standard and the combined noise level of the unit cabin was dominated by the radiated noise from wall panel in low frequency range. Based on the test results, design guidelines for the noise control of the unit cabin were fully established, such as the improvement of sound transmission loss between the cabin and corridor, and radiated cabin noise reduction.

The thesis is a comparative analysis of Infill Technologies between Korea's long-life Mock-up House, a study driven by 'Durability and Flexibility of Long-life Housing Technology Development' of R&D, and Japan's KSI experimental house, the major example of Japan's long-llfe housing. In terms of the domestic Mock-up House, a system of building the floor first was applied. The floor material of each housing unit required a development of dry heating component that is partially substitutable in order to avoid conflict with the finishing. Also, a development of a floor system that can counteract against the construction inaccuracy was required. In the Case of an outer wall, need to make the wall with the chassis. In the case of ceiling, need to develop the double ceiling system which is good for sound insulation. Also, in comparison to KSI experimental house in Japan, it would require to develop a wiring system of the ceiling which can react to the movement of the wall. Especially, to assure the flexible nature of an internal wall, it would desperately require the research and development of the products related to components and flexible system of mechanical/electrical/communication parts as well as supporting institutionalized system for this development. Furthermore, for KSI experimental house in Japan, it would be necessary to formulate a construction manual as well as a systematic and practical planning guide to invent a new interface rule which will secure simplicity of assembling, dismantling, installation and replacement of architectural components for which research development is quite insignificant at the moment. This effort will have to continue to give a solid direction for better application of such reference manual during construction and development of long life span apartment by public sector as well as private corporations.

사용후핵연료와 같은 고준위 방사성물질을 취급하는 핫셀 내에서 원격취급장치인 MSM의 작업영역을 벗어난 지역에 위치한 공정장치부품 유지보수공정을 개발하였다. 이를 위하여 대상 핫셀공정인 사용후핵연료 차세대관리공정에 대한 가상목업을 구축하였으며, 구축된 가상목업을 이용하여 MSM 작업영역 및 작업자 시각영역을 분석하고, 그래픽 가상목업의 충돌감지 기능을 이용한 서보 조종기의 경로계획을 수립하였다. 또한, 분석한 결과를 토대로, 서보조종기에 의한 사각지역 내 부품 유지보수 공정을 설정하였으며, 설정된 공정은 그래픽 전산모사를 통하여 검증하였다. 제안된 유지보수 공정은 실제 핫셀공정 수행시 유용하게 활용될 것이며, 그래픽 가상목업은 다양한 핫셀 공정에 대한 분석 및 작업자 훈련 시스템으로 활용하여, 작업 효율성 및 안전성 향상에 기여할 것으로 기대된다.
