From the research which sees the building which uses a natural control method with ecological architecture, continuity tried to divide the building which uses a physical control method with sustainable architecture. Ecological architecture analyzes the microclimate of the area and applies mining and natural ventilation leads and that the interior environment controls, the condition of the site actively and there is a possibility of seeing. Also sustainable architecture which is possible to lead and recycling and reuse of the resources and energy cyclic process of the construction resources to lead and the interior environment to control. Therefore the case where the facility system and structural system become integrated design organically in natural circulating method is many. Specially the sunshade system and double skin system are combined and structural system of the building and there is a possibility of having the envelope which form is feature. Today the buildings lead and the system integration process where the integral parts are systematic is demanded the interior environment which and an external form and that, they make they are there is a possibility of seeing. the environmental building which hits joins in with natural control method and the structure and facility system are integrated and has the tendency which is developed and there is a possibility of saying that a meaning with the alternative construction will be able to reduce the resources and an energy.

This research focuses primarily on the feasibility of applying bryophyte to man-made structures in modern urban environment. The study is based both on the role of bryophyte known in the process of the naturalization that life has come on the land and the physiological and ecological characteristics of bryophyte. The primary characteristics of this species lie in its desiccation-tolerance and poikilohydry that supports its enduring survival even under the desperate environmental conditions. The monitoring of applying bryophyte to man-made structures has shown us that bryophyte could control microclimate conditions, help to mitigate flood by reducing runoff, and lessen thermal conductivity, etc. The application of bryophyte to man-made structures has just started since 2002. Even though efforts to use bryophyte in greening man-made structures in Japan and Korea have resulted in both successes and failures, it is noticeable that there has been quite much technical progress in using this unique plant species.

Leaf temperature is complicated with the microclimate and the dry matter production in a plant community. But a daily change of leaf temperature varying by the locality in plant body or plant community is not yet clear. To resolve such a question, following experiment was designed; Helianthus tuberosus L., Glycine max L., Zea mays L., Impomoea batatas Lam., and Cucurbita moschata var. toonas Makino were planted in the different sandy loam, $2m{\times}2m-quadrat$, which has a eastern, southern, western and northern edge. In each plot 17-25 plants were planted and the distances between individuals spaced uniformly. And leaf temperature were measured by MR3-C type thermistor from 14th May through 20th August. It is seems that the upper leaf is affected by solar radiation, the lower leaf by released heat from the earth and the middle leaf by the conditions of both zones. Measuring the temperature of a leaf that is on terminal, central, left and right margins and base part, temperature of control plant in a leaf was sloped during about two hours from noon. It is noticeable as a "noon sleeping" phenomenon.henomenon.

Roof greening in a city can contributes to not only providing network opportunities for dispersed greenspace patches but also bringing more greenspaces into a city. In addition, it can help to flooding and microclimate control in the city. Recently, a number of roof greening projects have been introduced, mainly to public buildings and schools. Roof peening need to offers both ecological functions and convenience and satisfaction for urban residents. This study aims to provide directions for improving ecological benefits and visual preference of roof greening. Twelve scene slides were adopted to measure people's visual preference. The survey results show that landscape images can be categorized into naturalness, visual diversity, uniqueness, and spatial flexibility. Physical scenes can be classified into type I mostly greened by plants, type II mixed between convenience facilities and plants, and type III constructed with pond. People show high preferences to type I and type II when visual diversity is high. The results of this study suggest to enhance the visual preference by considering visual diversity when applying the ecological design methods to improve naturalness for roof greening.

The greenhouse is a complex system. It is subject to multiple input disturbances that are highly dependent on meteorological conditions, which are generally nonlinear and have a great influence on the agricultural production. The objective of this paper is to study the fuzzy logic technique as one of the most efficient technologies to control the greenhouse. The fuzzy logic controller (FLC) was developed to activate the actuator based on a ventilator was installed in an experimental greenhouse to obtain a desired temperature of the microclimate despite the externals disturbances.

Effective thermal management in a battery electric vehicle (BEV) is crucial for reducing energy consumption and maximizing driving range in cold climates. Consequently, original equipment manufacturers are actively investing in the development of local heating systems. Visualizing occupant thermal behaviors or comfort can readily provide valuable insights that would substantially impact the design and control strategies of such microclimate systems. This study uses MATLAB for three-dimensional visualization of human thermal psychology. The developed program enables qualitative assessment of occupant comfort in BEVs.

양어 및 수경재배 시설의 효율적 이용가능성을 검사하고 이의 효율적인 결합기술을 확립하기 위한 기초자료를 얻기 위하여 양어ㆍ수경병용온실에서의 미기상 환경 특성과 그 환경에서의 작물의 생육 반응을 검토한 결과는 다음과 같다. 1. 평균체중 428.6g의 틸라피아 성어는 147일간에 1.83배로 성장하였고, 평균 체중 12.9g의 치어는 61일 동안 1.37배의 성장율을 보여 정상적으로 성장하였다. 2. 미나리, 상추, 배추 및 실파 공히 수경재배구에서 보다 양어ㆍ수경병용구에서 초장, 생체중 등의 생육이 양호하였다. 3. 두 처리구에서 양액의 pH및 EC의 차이는 크지 않았으나 양액 온도는 양어ㆍ수경병용구에서 약 2$^{\circ}C$가 높았다. 4. 일중의 온도 및 습도변화양상은 평균온도가 각각 23.8$^{\circ}C$ 및 20.9$^{\circ}C$로서 양어ㆍ수경병용구에서 약 2.9$^{\circ}C$ 더 높았고 상대습도는 약 6%높았다. 3. $CO_2$ 농도는 양어ㆍ수경병용구에서 약 200ppm 정도 높았다. 6. 수경재배구보다 양어ㆍ수경병용구에서 잎의 순동화율이 다소 높았다. 그러므로 동일한 시설공간내에 수경재배와 양어를 병행한다면 난방비의 절감효과 뿐만 아니라 양어와 엽채류의 성장에도 상호보완적인 가중효과를 얻을 수 있을 것이다.

This study investigated physiological and subjective responses to different types of firefighter station uniforms made with various designs and materials. Six healthy males participated in this study that consisted of 20 min of rest, 30 min of treadmill exercise, and 30 min of recovery in a hot and humid environment (34℃ and 65%RH). The experimental clothing conditions were as follows. 1) a fitted T-shirt and trouser made of 100% polyester (FC-Uniform), and 2) flame retardant T-shirts made of acrylic and cotton as well as trousers with aramid and polyester, designed for overfitting (Control). There were no significant differences in the body temperature, and sweat rate between the two conditions; however, the heart rate with the FC-Uniform was significantly lower than Control (p=.025). The clothing microclimate temperature at the chest of the FC-Uniform was significantly lower than the Control (p=.037), and a difference of 1℃ was maintained until the recovery was complete. There were no significant differences in the subjective responses; however, participants experienced a humidity sensation faster with FC-Uniform in the recovery phase. The results indicate that changes in the design and material of firefighter station uniforms may have a positive influence on reducing the thermal stress of firefighters.

본 연구는 토지피복현황과 수림의 층위구조 등이 다양한 도시녹지를 대상으로 미기상 조절에 미치는 영향을 정성 및 정량적으로 파악하기 위해 녹지내의 기온 및 습도를 관측하였다. 그 데이터를 바탕으로 녹지내의 토지피복 현황과 그 비율, 녹적량과 기온 및 습도와의 관련성을 회귀분석 등에 의해 해석하였다. 그 결과 고온역은 포장면과 나지 주변에서, 저온역은 수림지 및 수면 주변에서 형성되었다. 또한, 수림(교목+소교목)으로 둘러싸인 수면, 소하천 주변에도 저온을 나타냈다. 습도는 기온분포에 거의 대응하는 형태로 고온역이 저습역이고, 저온역이 고습역으로 나타났다. 녹지가 미기상조절효과를 갖는 메커니즘은 토지피복비율의 종류,그 비율의 차이에 따라 미기상조절효과의 정도가 서로 달랐다. 더욱이 각 녹적량의 증가는 수고에 관계없이 모두 기온은 떨어뜨리고 습도는 상승시키는 효과를 보였다. 그 효과의 효율은 교목, 소교목, 관목의 순이다. 지금까지의 실증결과로부터 고온완화에는 수림지, 수면,초지의 순으로, 그 비율을 증가해서 배치하면 효과가 커지고, 같은 방법으로 습도의 상승에는 수면, 수림지, 초지의 순으로 그 비율을 증가해서 배치하면 효과가 높아진다. 그 효율성을 고려하면 수면, 소하천을 핵으로 그 주변은 교목 중심의 수림이 좋고, 그 층위구조는 단층림보다는 2∼3층의 혼효림이 미기상조절에 미치는 효과가 크다.
