The STELLA program was launched to support the PGSFR development in 2012 and for the 2nd stage, the STELLA-2 facility was designed to investigate the integral effect of safety systems including the comprehensive interaction among PHTS, IHTS and DHRS. In STELLA-2, the long-term transient behavior after accidents can be observed and the overall safety aspect can also be evaluated. In this paper, the basic design concept from engineering basis to specific design is described. The design was aimed to meet similarity criteria and requirements based on various non-dimensional numbers and the result satisfied the key features to explain the reasoning of safety evaluation. The result of this study was used to construct the facility and the experiment is on-going. In general, the final design meets the similarity criteria of the multidimensional physics inside the reactor pool. And also, for the conservation of natural circulation phenomena, the design meets the similarity requirements of geometry and thermo-dynamic behavior.

Color is an important subject of interest for cognitive developmental stages of children and it also correlate to emotional and physical development. Children can acquire concept of color by 'play'. Color play can be experienced to children through diversity activity and theses activities contain creative craft art activity. The color-paly with art activity for kids can be called 'kids color-design play'. Recently, indoor playgrounds are rapidly grow-up because parent's concern degree that about play activity get higher. The indoor playground being enlargement and it contains various paly contents. Color-design play is also enacted animatedly in kids indoor playground. The great part of color-design plays are enacted through program that needs teaching. On the other hand, color-design play facility that children can play spontaneously is not composed sufficiently. Therefore this study aim at design proposal of 'Kids color-design playground apparatus' in indoor playground.

We consider facility layout problems, where mn facility units are assigned into mn cells. These cells are arranged into a rectangular pattern with m rows and n columns. In order to solve this cell type facility layout problem, many approximation algorithms with improved local search methods were studied because it was quite difficult to find exact optimum of such problem in case of large size problem. In this paper, new algorithms based on Simulated Annealing (SA) method with two neighborhood generation methods are proposed. The new neighborhood generation method adopts the exchanging operation of facility units in accordance with adjacent preference. For evaluating the performance of the neighborhood generation method, three algorithms, previous SA algorithm with random 2-opt neighborhood generation method, the SA-based algorithm with the new neighborhood generation method (SA1) and the SA-based algorithm with probabilistic selection of random 2-opt and the new neighborhood generation method (SA2), are developed and compared by experiment of solving same example problem. In case of numeric examples with problem type 1 (the optimum layout is given), SA1 algorithm could find excellent layout than other algorithms. However, in case of problem type 2 (random-prepared and optimum-unknown problem), SA2 was excellent more than other algorithms.

유독성 물질로 인한 환경오염사고 방지 및 수환경 보호를 위해 정부에서는 완충저류시설의 설치를 제도적으로 추진하고 있다. 완충저류시설은 사고유출수 및 초기우수를 저류하여 수질오염을 방지하는 긍정적인 역할에도 불구하고 관련연구 및 시설의 설계를 위한 구체적인 가이드 라인은 부족한 실정이다. 본 연구에서는 완충저류시설 설계 도서를 분석하여 어떠한 항목을 설계에 반영하였는지 분석하였다. 분석결과를 바탕으로 설계항목을 도출하고, 완충저류시설 관계자의 의견을 반영하여 완충저류시설의 설계에 필요한 항목을 제안하였다.

For prevention of the school violence, many researchers have been conducted the studies based on crime prevention through environment design(CPTED) in the architecture planning phase. However, besides of architecture planning, the study considering the aspect of the facility management is needed during life cycle of educational facilities. In this study, the objective is to propose the effective school facility management for violence prevention based on CPTED method during life cycle of the facilities.

학교시설은 근린주거지역의 핵심시설로서 물리적, 사회적으로 중요한 위치를 차지한다. 이러한 학교시설용지가 활용되지 못하는 경우, 규모와 입지의 특성상 지역주민들의 환경을 저해하는 요인으로 작용하게 되며, 지역의 토지자원에 막대한 낭비를 초래한다. 따라서 학교시설용지의 미매각화 현상에 대한 원인을 규명하고, 이를 미연에 방지하기 위한 제도의 마련이 필요한 실정이다. 한편, 발생한 미매각 학교용지에 대해서는 용도의 전환 등을 통하여 빠른 활용이 가능하도록 유도 할 필요가 있다.

환경오염이 심각해지면서 자연재해가 빈번해지고 그 피해도 증가하고 있다. 또한 인구 과밀화로 사회적 재난도 빈번해지며 지역과 범위, 피해가 다양해서 예측이 어렵다. 재해가 다양해지고 피해규모도 커지면서 재해 시 이재민의 규모와 대피기간이 다양해졌다. 주거를 상실한 이재민에게 2차 피해로부터 보호받을 시설을 신속하게 제공해야 한다. 이에 조립식 주택을 지원하고 있지만 보급이 어렵다는 단점이 있다. 본 연구에서는 대피시설의 수용능력이 부족하거나 대피시설이 미비할 때 신속한 보급이 가능한 실외용 임시주거시설을 계획하는 것이 최종 목표이다.

This study was conducted to develop proper model for cold storage facility that could of for uniform heat movement and air movement f3r green grocery and improve improper design of the existing container-type cold storage facility. For that reason, new model(dome-type) cold storage facility was developed using 3-D CFD(computational fluid dynamics) simulation. The size was 6m${\times}$6m${\times}$5m. Its size and configuration were same to simulation model. Unit cooler was designed to send cold air in 4 side ways. A dome-type cold storage facility showed uniform distributions of air temperature and velocity because cold air was forced to move down along the ceiling and the wall and then circulated to the unit cooler from the central part of the floor. Dome-type cold storage facility also showed by low wind velocity, below 1 m/s that could minimized cold damage and quality deterioration.

The purpose of this study is the examination of the possibility as grasping the circumstance which is the time required from programming to design process in schools which are established newly and investigating the consciousness of the user's participation, because we need a user participation process in the programming to design process to improve the level of design. The above-mentioned purpose is the reason that this study composes the second grade. This study shows the entirely necessary time to work each step as collecting the data of programming-design process to 33 schools which are established for 4 years between 2002 and 2005 by Busan metropolitan city office of education, and the reason why they need a time each step. As the result of this study, the school established by the purpose of land development business takes more time than the school of learning environment improvement and of reconstruction & transfer case. Because of the change of land for school, we have to take a cautious approach to select the land for school in the future when developing the land. The time required from programming to design process in reconstruction & transfer case is the shortest even though it is different a little according to the kind of schools.
