Purpose: As declines in the quality of residential environments occur, such as urban heat island effect, tropical night phenomenon, and violations of right to light and privacy due to urban densification and high rise building, these problems are emerging as social issues. In order to improve these issues, design factors which consider environmental aspects must be selected when planning apartment complexes, and ways to reflect them in the planning phase must be explored. Method: In this study, the analytical hierarchy process(AHP) was used to deduce design factors that considered environmental elements during the planning of apartment complexes. Furthermore, the priority and weight for each evaluation index were assessed. The objective was to propose a guideline for planning apartment complexes by finding the best solution for each evaluation index using complex weight values. Result: Floor area ratio was selected as the most important evaluation criterion in the environmentally conscious evaluation index for apartment complex planning. The shape and placement of skylights were selected as the most important evaluation criteria in the sunshine environment for a pleasant residential environment. Ground surface cover design was selected as the most important criterion in the outdoor thermal environment index for improving the microclimate within cities and apartment complexes. Thus, the results of this study can serve as an investigation guideline that concerns policy and regulations, and as reference data that can be used in planning apartment complexes.

The actual clothing conditions were surveyed to diagnose clothing condition of collegians in the view point of adaptation to the thermal environment in fall. Then, clothing climate, physiological responses, and subjective sensation were investigated through wearing trials on human subjects in climatic chamber based on the results from the survey. Factors to evaluate validity of clothing condition were clothing weight, clothing climate, physiological responses of human body, and subjective sensation. Adaptability of this research to thermal environment was compared to the results of Toda's and Duno's of Japan, Chung's results of Korea rural area, and Winslow's clo value. The standard values for wearing trials were values at comfortable zone, such as $32{\pm}1^{\circ}C$ of temperature and $50{\pm}10%$ of humidity inside clothing, $36.5{\sim}37.3^{\circ}C$ of ear temperature and $32.2{\sim}34.3^{\circ}C$ of mean skin temperature. Clothing weight per body surface area was 680.9 $g/m^2$ in male and 526.7 $g/m^2$ in women. Cold resistance ability of collegians was superior to Japanese and American, and similar to rural male in Korea. According to the examination of clothing adaptability with clothing weight from the investigation on physiological responses and the actual clothing conditions survey, following were found. Temperature inside clothing ($29.8{\sim}32.3^{\circ}C$) was normal, and humidity inside clothing (32.2~54.8%) was at comfortable zone. Mean skin temperature was at its comfortable zone. Therefore, 615 $g/m^2$ in male and 525 $g/m^2$ in female were a desirable wearing condition.

LID 기술은 다양한 토지이용에서 발생되는 비점오염원(NPS)을 저감하는 기술이다. 점오염과 비점오염원의 증가와는 별도로 불투수지역 내 도심지는 일반적으로 도시기후에 영향을 준다. 본 연구에서는 LID 기술이 도시열섬현상(UHI)을 저감에 대한 영향분석을 공주대학교를 대상으로 수행하였다. 공공부지인 학교는 보행자의 통향량, 차량운행이 특정시기에 증가되기에 일반적인 원단위 부하량보다 낮은것으로 나타났다. LID 시설은 강우유출수 내 오염물질을 여재부 내 흡착, 여과 등을 통해 오염물질이 저감되는 것으로 분석되었다. 또한 LID 시설 내 강우유출수 저감 및 저류를 통해 유역 내 불투수면적보다 최대 7.2 ℃ 낮은것으로 나타났다. 따라서 LID 시설은 비점오염물질 저감 및 도시열섬 현상을 완화시키는 것으로 분석되었다.

본 연구는 온실효과로 인한 기후변화에 대응하고자 산림생물다양성특정지역(풍혈)에 대한 생물학적 가치와 환경요인을 분석하여 풍혈에 대한 기초자료를 작성하고 이를 통해 산림생물다양성 보전 및 관리를 위한 방안을 수립하고자 수행되었다. 국내 분포하는 풍혈 25개소 중 지형학적 유형에 따라 분류한 애추형, 동굴형, 함몰형 풍혈 6개소를 선정하여, 지하에서 바람이 불어나오는 전석지를 경계로 구분하여 풍혈 내·외부로 나누어 2020년부터 2021년까지 계절별로 기상정보와 관속식물상을 조사하였다. 여름철에 6곳의 풍혈 모두 풍혈이 위치하는 지역보다 기온이 낮게 나타났다. 6곳의 풍혈의 관속식물은 101과 350속 621종 18아종 57변종 7품종 703분류군으로 조사되었다. 한반도 특산식물은 29분류군, IUCN 지정 희귀식물은 위급종(CR) 5분류군, 위기종(EN) 3분류군, 취약종(VU) 4분류군 등 총 22분류군이 확인되었다. 식물구계학적 특정식물은 V등급 4분류군, IV등급 27분류군, III등급 48분류군 등 총 168분류군, 북방계식물은 129분류군, 한반도 기후변화 적응 대상 식물 300의 북방계식물 100종 중 총 22분류군이 확인되었다. 침입외래식물은 48분류군, 생태계교란식물은 7분류군이 확인되었으며, 귀화율은 6.8%로 나타났다.
