  • Sport has no age limit and can be done anywhere and in any condition with minimal equipment. The existence of sports spaces in all parts of the world is considered a citizen's right. One of the activities carried out in this field is installing sports equipment and structures in parks and encouraging citizens to use this equipment for physical health with the least cost and facilities. Installing sports structures in open spaces such as parks is a practical step for developing citizens' sports. Although using devices in parks is acceptable, it is more critical to meet scientific and technical standards. The components of these structures must have high strength and endurance against changes in environmental conditions such as humidity, temperature difference, and corrosion. Among the various causes of material degradation, corrosion has always been one of several fundamental causes of metal equipment failure. Sports structures in open spaces are not safe from corrosion. Uniform corrosion is the most common type of corrosion. This corrosion usually occurs uniformly through a chemical or electrochemical reaction across the surface exposed to the corrosive environment. Rust and corrosion of outdoor sports structures are examples of this corrosion. For this reason, in this research, with the green synthesis of silica nanoparticles and its application in outdoor sports structures, the life span of these structures can be increased for the use of physical exercises as well as their quality.

  • The purpose of this study is to form a night-view at a university to satisfy users through case studies of four representative university campuses with analyzing the lighting conditions and facility satisfaction. The result of this study is following. From the present lighting status, there are 664(l9types) lightings at Kyunghee University, 350(17types) at Sungkyunkwan University and 437(l9types) at Ajou University. Main materials of the lightings are metal, iron and stainless. Moreover, most illuminants are white-colored metal-halide lamp. There is no specially designed lighting facility because ready-made goods were used. Furthermore, the locations of lightings are not suitable so some are useless. Most main spatial illuminations are not satisfying outdoor standard, so it can be concluded that the designs of present campuses are not carrying on with-out plans. From the result, present campus lighting does not satisfy the desire of users in aesthetic and functional point of view but consider the luminosity. However, even though the luminosity does not standardize the law. It is because the design does not reflect a suitable standard with desire of users and it does not have a long term plan. Moreover, the campus design has no study about development plan even though it has enough green area which has a potential possibility to overcome the lack of green areas in a city. Therefore, it is needed to design a comprehensive campus plan which satisfies the desire of students and residents with considering promotion of excitement and harmony through adjusting luminosity of the lighting facilities and supplying various lighting resources.

  • The physical environment can dramatically affect students' feeling and their behavior, educational attainment, and the way in which we do school activities. Unlimited access to campus areas without appropriate securities have reported an increase of crime in school area and safety issues has encouraged school facility planners to install securities devices at every corner of buildings. However, it is still questionable whether this approach is enough to protect students and staffs from the victimization of crime, including thefts, burglaries and sexual offences. There has been continued doubt about the safety of educational facilities where individual college students are studying and enjoying extra-curricular activities. Therefore, the purpose of this study is intended to investigate the effects of perception of safety by students on the level of academic performance at public outdoor environment of university campus. An extensive literature noted that the central element of modern school design principle mainly holds the theory of crime prevention through environmental design (CPTED) and the concept of defensible space. The second generation of CPTED also focused on social soft issues as well as situational factors, which extends beyond mere physical design to include social factors. The correlation analysis found that the effect of sense of safety does appear to be statistically significant on the facilitation of academic achievement. However, the analysis of Chi-square concluded that the perception of safety was not related to demographic and socio-economic profiles of the group except for gender. Further, stepwise multiple regression analysis revealed that the most prime predictor for academic achievement were 'safe public outdoor space/paths' at university campus environment, implying careful design of public open space and sidewalks based on the guideline of CPTED. The study also demonstrated that as the level of positive perception of safety rose, the overall academic achievement also responded to the specified rate (${\beta}=.99$). Finally, the findings reinforce an evidence that high-quality school environments are a positive factor in student academic performance.

  • The purpose of this study is to clarify the components for the improvement of outdoor spaces in farmyards and to suggest guidelines for the planning of these spaces. The objects of this study were the general farmyards located around farmhouses which had government support for the construction of on-site gardens. The results were as follows: 1. Although over 50% of the general farmyards did not have gardens, most gardens of farmyards (90% and over) featured trees and/or flowers. This demonstrated that the residents of the farmyards thought positively about green spaces. 2. With the establishment of a garden, the self-image of the household improved along with the physical environment. Thus, the construction of the garden brought about psychologically and physically positive results. 3. Regarding the degree of satisfaction with green space and shade, the rate of farmyards with gardens was higher than those without. With more government support for developing such green spaces, satisfaction with them could increase. The same result was obtained regarding the degree of satisfaction towards visual harmony with nearby farmyards, indicating that neighboring farm households want to have positive relationships with one another. 4. The frequency of use of living space increased through the construction of gardens in farmyards, in spite of decreased working space. %is aspect could be used as data in the planning of gardens in farmyards. 5. The perceived necessity of gardens in the general farmyards and desire to construct new gardens rose. This preference was high in gardens with abundant greenery and a lot of rest facilities. This study suggests those reasons result from a poor farm economy. With government support, general farmyards without gardens could construct gardens. And we might infer that the residents' desire to construct a garden in general famyards had been influenced by a neighbor with a garden.

  • 본 논문은 현재 유선방송 기술기준에서 CDMA 이동통신서비스 대역의 누설전자파 기준이 적절한지를 검증하고자 하였다. 먼저, CDMA 2000 1X 기지국 장비를 통한 실험결과로부터 CDMA 이동통신 시스템의 최대 허용 간섭 레벨은 -110dBm/1.23MHz인 것으로 분석되었다. 이를 토대로 이동통신기지국에 거의 영향을 주지 않을 케이블 방송 옥외 전송설비의 누설 간섭전력의 임계레벨과 누설전자파 세기를 산출하였다. 일반적으로 옥외에서 측정되는 외부시스템의 배경 간섭레벨인 -100~-80dBm/1.23MHz에 대해서 허용될 수 있는 케이블 방송 설비의 누설전자파 임계치는 현행 유선방송 기술기준을 만족시키지 못하였다. 이것은 현행 기술기준이 지나치게 최악의 경우를 상정하여 설정되었음을 의미하므로 이동통신사업자의 실제적인 기지국 조건을 적용하여 합리적인 기술기준을 마련하여야 할 것이다.

  • 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.

  • 초등학교 옥외공간은 어린이의 가장 가까운 생활공간이자 교육공간이다. 새로운 교육 패러다임의 변화에 의해 초등학교 옥외공간의 새로운 역할과 방향에 대한 필요성이 대두되고 있다. 하지만 어린이의 시선과 요구에 맞춘 공간 조성은 미비한 실정이다. 실제 이용자인 어린이의 구체적이고 다양한 요구를 담아내지 못하는 현실 속에서 이러한 아동참여디자인 과정의 도출과 적용 과정은 의미가 있다고 할 수 있다. 본 연구는 초등학교 옥외공간의 아동참여디자인 과정에 의한 설계가 필요함을 인식하고, 관련 연구 및 관련 법규의 이론적 고찰을 통하여 아동참여디자인 과정 모형을 구축한 후, 서울 돈암초등학교 옥외공간 설계에 적용하였다. 스스로의 의견을 제안하고 표현하는 데에 미숙한 어린이가 쉽게 참여디자인 과정에 참여하고 의견을 표현할 수 있도록 흥미로운 도구와 게임 방법 등을 포함하여 디자인 과정을 구성하였다. 본 연구에서 도출한 아동참여디자인 과정은 흥미유발 및 대상지 인지단계, 기대파악 및 표현단계, 계획요소도출 단계, 공간구상 및 공간배치단계, 의사결정 및 최종계획안 도출단계 등의 5단계로 구성된다. 이러한 과정을 서울 돈암초등학교 옥외공간의 계획 및 설계 과정에 적용하였다. 본 연구는 참여자 중심의 설계와 전문가 중심의 설계는 그 디자인 목표가 다르다는 것을 전제로 하여 결과물보다는 디자인 과정에 의미를 두고 가시적으로 보이는 물리적인 디자인의 개선뿐만 아니라 공간에 내재되어 있는 비물리적인 디자인의 개선을 기대한다. 즉, 참여디자인 과정을 통하여 시설물 개선 및 배치계획 제안이라는 하드웨어뿐만 아니라 어린이의 참여와 관심이라는 소프트웨어를 모두 개선하여 어린이가 바라는 초등학교 만들기의 초석을 만들고자 하였다. 본 연구는 초등학교 옥외공간의 실제 이용자인 어린이의 요구를 효과적으로 반영할 수 있는 아동참여디자인 과정을 도출하여 과정 모델의 형태로 제시하였다는 점과 이 과정을 대상 초등학교 옥외공간에 적용하여 설계에 반영하였으며, 이 설계 경험을 바탕으로 공간에 대한 참여의식과 주체의식, 주인의식과 책임의식을 고양시킴으로써 어린이가 주체가 되는 초등학교 옥외공간을 조성하였다는 점에 의의를 둔다.
