We measured VOCs and NO2 in the indoor and outdoor air at 125 houses in Jeollanam-do and Gyeongsangnamdo, from March 2007 to January 2008. The concentration of benzene measured in the Gwangyang survey group was higher than in Yeosu and Hadong, and showed a statistically significant difference from Yeosu (p<0.05). The concentration of toluene in outdoor air was highest in the Gwangyang survey group. The concentration of NO2 measured in the Yeosu survey group was higher than in Gwangyang and Hadong, and showed a statistically significant difference from Hadong (p<0.01). According to the results of a correlation analysis, VOCs (benzene, toluene, xylene, ethylbenzene) exposure of individuals showed a significant correlation with the residential indoor air (p<0.01). Also, VOCs of residential indoor and outdoor air showed a significant correlation (p<0.01). The concentration of NO2 exposure of individuals measured in the Yeosu comparison group showed a high correlation with the residential indoor air.

Shelter that communication equipment and on-equipment material are mounted on is transported by airplane, vehicle and has a function such as waterproof and shielding EMI. Maintaining proper inside temperature of shelter is important in order to operate equipment. Accordingly proper cooling capacity of cooling equipment which installed on the shelter is important for equipment and operator. To calculate proper cooling capacity, There are some considerations such as environmental factors and equipment in the shelter. In Korea solar irradiation and outdoor temperature is difference in accordance with geological characteristic. Also electric equipment mounted on the shelter is increased by development of technology. But the capacity of air conditioner is not changed thus there is a problem about operating equipment. In this paper, Compare cooling capacity of shelter when using air conditioner that is not enough cooling capacity and calculate proper cooling capacity to consider geological solar irradiation and outdoor temperature.

The purpose of this study was to investigate the differences in various fashion lifestyle segments’ perceived benefits and design preferences for outdoor clothing to improve the development of outdoor clothing. Data were collected by questionnaire from 600 subjects aged 30 years and over with experience purchasing outdoor clothing in the past year. Frequency analysis, factor analysis, cluster analysis, reliability analysis, ANOVA, and chi-square analysis were used for the data analysis. The results of this study were as follows. Four segments were identified based on fashion lifestyle: manifoldly conscious, sensation conscious, practicality conscious, and brand conscious. Perceived outdoor clothing benefits generated three dimensions, including premium brand, practicality, and functionality, and preferred image produced two factors, tasteful/refined and comfortable/casual. Significant differences were found in the purpose of purchasing outdoor clothing, perceived benefit, and image and t-shirt pattern design preference among the segments. The manifoldly conscious group had a higher tendency to pursue various benefits and images of outdoor clothing and to prefer t-shirt textile designs with foulards and stripes. The sensation conscious group considered fashion and individuality in daily life but not in outdoor clothing. The practicality conscious group showed a preference for simple and casual styles with functionality and foulard patterns for t-shirts. The brand conscious group tended to prefer a striking design to functionality. This study is expected to be used as preliminary data for merchandising planning of outdoor clothing.

최근 강풍으로 인한 옥외광고물의 파손 및 추락으로 인해 불특정 다수에게 인적 및 물적 피해를 야기하고 있다. 옥외광고물은 사유시설과 공공시설물의 성격을 모두 갖기 때문에 옥외광물로 인한 피해를 저감하는 것은 개인의 노력뿐 아니라 제도 및 규정을 통해서도 이루어져야한다. 이러한 피해는 강풍에 취약한 옥외광고물의 내풍설계 기준의 미비가 가장 큰 요인으로 인식되고 있어 본 연구에서는 옥외광고물의 내풍설계 표준을 제시하였다. 이를 위해 풍속에 영향을 주는 옥외광고물 설치위치의 주변 풍환경이나 높이, 설치위치 등 풍속과 관련한 요소를 반영하였으며, 건축구조기준 2015(안)의 기본풍속도와 풍속보정 절차에 의한 풍하중 산정 과정을 제시하였다. 이 과정에서 공학적 판단이 요구되는 옥외광고물 설치위치 주변의 지표조도구분 및 지형계수 평가에 대해 정략적으로 적용할 수 있는 기준을 제시하였다. 또한 비전문가 관점에서 적용하기 용이하도록 가능한 단순화된 정량화 절차를 제시하였다.

This paper analyzes the location, landscape elements, and outdoor space composition in the Korean Sosu seowon and Chinese Bailudong seowon. The Sosu and Bailudong seowons were designed to fit well into similar valleys, and they share the approach of Jwa hak woo myo, which means the sacrificial space is on the right and the educational space is on the left. The two seowons each have unique layout characteristics, which reflect topographical features. In the case of the Sosu seowon, the buildings have different orientations, creating a natural arrangement of structures. By contrast, in Bailudong seowon, buildings have a fixed orientation and a formal serial-parallel arrangement along five abscissa axes and one longitudinal axis. Pedestrian systems were established in both seowons, designed to reflect the hierarchical order of the buildings. The Sosu seowon adopted the pedestrian system that encouraged strolling, while the Bailudong seowon’s orthogonal circulation system was set up lengthwise, in parallel with the transverse. The component buildings used for worshiping ancestors and giving lectures, as well as the supporting spaces, were created at the start of the building process, while various other buildings were built to meet the needs of later periods. The two waterscape facilities are also very different: the Takcheongji (pond) at the Sosu seowon symbolizes clarifying the mind through study, while the Panchi (pond) at the Bailudong seowon merges with the Lishengdian (shrine) to contain and represent Confucian culture. The rock carvings at the two seowons differ in both quantity and content. However both sets of rock carvings incorporate Neo-Confucian meanings designed to encourage students to cultivate themselves. From the perspective of earlier literature, both seowons took the meaning of trees very seriously, although they planted different types of trees in their grounds.

This study attempts to investigate the impact of pollution by VOCs at schools located around Shihwa national industrial complex. Schools around the Shihwa national industrial complex were divided into two categories based on location, with five schools located near the industrial complex and five schools located near housing development. Samples of the indoor air and the outdoor air were collected from each classified school and analyzed to evaluate the impact of the industrial complex on each school through a comparison and to find the correlation between them. In combination with this, this study attempted to conduct comparative evaluations of the schools in which there might be relatively higher indoor air pollution since new construction and extension or remodelling had recently been carried out with other schools. The samples collected from 10 places in total were analyzed, using GC/MS. TVOCs, and individual component of VOCs, were detected in the schools near shihwa national industrial complex at higher levels than in the schools nearby housing development. TVOCs were detected at the schools in the industrial complex st levels of 166.5 μg/m3, that is, about 1.5 times higher than the level detected at the schools outside the industrial complex. TVOCs were found in the indoor air of the schools that had been extended or remodelled less than 3 years ago at levels of 188.8 μg/m3, while in schools where more than 3 years had passed since extention or remodelling they were found at levels of 97.5 μg/m3, meaning they were about 1.9 times higher in schools in the first 3 years.

Despite both domestic and overseas markets are depressed due to the global financial crisis - the apparel industry is no exception, the market for the outdoor wears including the hiking ones has been recording a high growth rate, making the outdoor wear a high growth industry. The purpose of this study was to provide some basic data useful to our outdoor businesses to help them respond to consumers' needs in the rapidly growing outdoor markets. For silhouettes, the point was given primarily to the oblique cutting to have it follow the human body curves and thereby, look natural and slim. Another point was given to the color schemes along the cutting lines, so that an effect of optical illusion could be created to make the wears look slim making use of lines and colors. On the other hand, in consideration of the rapidly changing weather conditions during hiking, the details were designed practically by setting appropriate hip lengths, using attachable/detachable hoods as well as applying the Velcro & rubber band-type set-in sleeves for the tail edges. As discussed above, the researcher analyzed the design elements for the outdoor wears and developed some sensuous designs meeting consumers' needs to help our outdoor wear businesses to expand their target base, while awakening them of the importance of the outdoor fashion.

The concern of fine particle (PM2.5) management of outdoor environments has been increasing due to its exposure and related health effects in Korea. As a result, PM2.5 standard in atmosphere environment was regulated in 2015. On the other hand, indoor PM2.5 standard has been required because most people spent their times in indoor environments. In this study, we measured the PM2.5 and PM10 concentrations both indoor and outdoor environments of public-use facilities such as underground stations, underground shopping centers, and nurseries for 24 hour with filter-weighing method in Seoul and Daegu. Measurement duration was from March to April in 2014 during the Asian dust period. At all measurements, indoor to outdoor (I/O) concentration ratios exceeded 1 except 1 day nursery in Daegu in spite of Asian dust period. The ratios of PM2.5 to PM10 concentrations ranged from 0.63 to 0.75 in indoor environments, and from 0.63 to 0.82 in outdoor, indicating that PM2.5 should be carefully managed in indoor environments as well as outdoor atmosphere.

This study analyzed the effects of consumers’sense of community regarding outdoor brands on behavioral commitment, purchasing satisfaction, and repurchasing intention and analyzed the effects of behavioral commitment and purchasing satisfaction on repurchasing intention. Additionally, this study analyzed the differences in sense of community, behavioral commitment, purchasing satisfaction, and repurchasing intention according to the types of outdoor consumers’consumption values. A survey was conducted from July 20th to 30th, 2015, and 527 responses were used for the analysis. The results of this study are as follows. First, consumers’sense of community regarding outdoor brands was classified into mutual influences, sufficiency necessity, emotional connectedness, and sense of belonging. Second, outdoor consumers’sense of community had positive impacts on behavioral commitment, purchasing satisfaction and repurchasing intention. Third, outdoor consumers’behavioral commitment and purchasing satisfaction had positive impacts on repurchasing intention. Fourth, there were differences in the outdoor consumers’sense of community, behavioral commitment, purchasing satisfaction, and repurchasing intention according to the types of consumption values. Therefore, outdoor brands can strengthen the relationship with customers considering values and behavior, suggesting the need for a strategy that promotes consumers’sense of community with sustainable management activities that save the environment and local community.

Introduction 5 working days a week and wellness trends, that allows more consumers to actively enjoy outdoor activities, has led to a rapid growth in the outdoor clothing market. Buyers of outdoor clothing perceive them as causal and functional clothes that they can wear comfortably in daily life as well as for outdoor activities such as hiking and fishing (Park et al., 2002). There is an increased interest in outdoor activities by seniors who engage in various hobbies for health. Active seniors are energetic retirees who actively enjoy their retirement. They have emerged as a new consumer group in the inactive culture market (such as travel and the performing arts) due to their enjoyment of activities (such as language study, computer education, cosmetic/beauty treatments and sports) that is different from previous generations of older people (Korean Economic glossary, 2014). The most striking characteristic of active seniors is their generous investment in self-development based on secure assets and retirement income. Many studies have been done on senior citizens based on age that have examined body types (Ahn, 2003; Kim, 1995; Lee & Kim, 2007) and original clothing forms (Lee, 2003; Nam & Choi, 2002; Moon, 2008). However, these studies did not fully reflect the needs of active seniors interested in clothing. Additionally, most studies were conducted on female seniors with few studies on male seniors. It is necessary to accept and understand changes in the body types and physical functions of seniors body types and physical functions that accompany age and changing aesthetic sense with styles that are differentiated from existing elderly groups in regards to clothing for active seniors. A study on older men's body classification (Kim & Lee, 2003) indicated that the characteristics of older men's body types were not fully considered because a clothing sizing system was not separately established for older people. Most outdoor clothing companies produced patterns for a young generation. This study was conducted on the outdoor jacket wearing pattern of active male seniors. The results of this study can be used to design outdoor jackets that are produced at a reasonable price with a wearable function useful for outdoor activities and daily life.

This study understood what effect was produced on the purchasing decision making of outdoor wear by a shopping orientation, fashion involvement and demographic characteristics offered practical suggestions as to what effect was produced on the store selection criteria, product selection criteria for purchasing decision making in purchasing outdoor wear. This research was conducted through a questionnaire survey, and 397 males in were collected for analysis. The results were as follows. First, shopping orientation group was classified into hedonic shopping orientation group and utilitarian shopping orientation group. And it was classified into high fashion involvement group and low fashion involvement group according to fashion involvement. Product selection criteria were classified into 2 factors such as intrinsic attributes and extrinsic attributes. And store selection criteria were classified into 4 factors such as store atmosphere, store environment, promotion and salesmen. Second, there was partly significant difference in product selection criteria, and store selection criteria between utilitarian shopping group and hedonic shopping group. Third, there was significant difference in product selection criteria and store selection criteria between high fashion involvement group and low fashion involvement group. Finally, there was significant difference in the and according to age, job, and income among demographic characteristics.

The consistency of the outdoor benzene, toluene, ethylbenzene, xylene and TVOC appeared respectively with 0.512 μg/m3, 0.474 μg/m3, 1.177 μg/m3, 0.862 μg/m3 and 22.306 μg/m3. Personal exposure, the residential interior, interrelationship analytical result Benzene of outdoor consistency and Ethyl benzene, Xylene and TVOC personal exposures with the interior and outdoor consistency showed the interrelationship which considers(p < 0.01). VOCs consistency which it follows in residential type the detached home > the multi generation house > the consistency price came out with the apartment order, VOCs consistency which it follows construction year possibility the year valence which is built 4 years at once rises the consistency appeared more highly the case where the case is above 4 years than.

Residential thermal conditions are important because people spend the majority of their time in the home environment. Indoor temperature and relative humidity(RH) were measured continuously over 1 year in 14 residences in Seoul, Korea. The relationship between residential indoor and outdoor conditions were determined by four meteorological parameters-temperature, apparent temperature(AT), RH, and absolute humidity(AH). Outdoor and indoor temperature, AT and AH were closely correlated, but RH was not. While indoor temperatures, AT, and AH were significantly higher than the corresponding outdoor levels, indoor RH was significantly lower than outdoor RH. Regression models between indoor and outdoor temperature detected a heating threshold at 15.0oC of outdoor temperature. The indoor thermal conditions were significantly different by the two residence types. Indoor temperatures in apartments were lower in summer and higher in winter than those in detached houses. However, indoor RHs in apartments were lower than in detached houses. During tropical nights, the daily temperature range was higher in residences with air-conditioning than in naturally ventilated residences.

The objectives of this study were to characterize the factors affecting exposure to the VOCs and NO2 in the vicinity of Gwangyang industrial complex. The VOCs and NO2 levels were measured for residents of an exposure group (industrial area within 5 km) and a control group (15 km farther), respectively using the VOCs and NO2 filter badge as a passive sampler from August to September 2006. The means of indoor, outdoor, workplace and personal exposure levels of benzene were 1.10 ppb, 0.94 ppb, 1.85 ppb and 2.35 ppb respectively in the exposure group. The means regarding toluene for the exposure group were 9.29 ppb indoor, 8.09 ppb outdoor, 14.5 ppb workplace, 14.2 ppb personal exposure. The means regarding ethylbenzene were 4.96 ppb(indoor), 4.45 ppb(outdoor), 6.84 ppb (workplace), 6.10 ppb(personal exposure), and the means regarding xylene were 0.10 ppb(indoor, outdoor), 0.18 ppb(workplace) 0.17 ppb(personal exposure). The means for the indoor, outdoor, workplace and personal exposure level of NO2 were 18.40 ppb, 18.51 ppb, 18.59 ppb, 18.80 ppb respectively in the exposure group. Correlations between personal exposures and workplace concentrations of individual VOCs and NO2 exposures, and each of the microenvironment was statistically significant.

팥나방 (Matsumuraeses phaseoli) (나비목: 잎말이나방과)은 한국에서 팥 (Vigna angularis)과 녹두 (Vigna radiata)의 꽃과 꼬투리를 가해하는 주요 해충의 하나인데, 수원지방에서 이 곤충의 발육 특성과 월동태를 추정할 목적으로 야외 (37°16′N 126°59′E 35ASL) 조건에서 인공사육을 통해 발육과정이 관찰되었다. 갓 부화한 유충 집단들은 약 14일 간격으로 인공사료를 이용하여 1년 이상 야외에서 사육되었는데, 봄에서 고온인 여름철로 감에 따라 발육기간이 짧아지고, 가을철로 감에 따라 다시 길어지는 경향이었다. 유충 혹은 번데기 발육에서 여름철 하면 현상은 발견되지 않았다. 2008년 10월 8일 사육이 시작된 집단은 번데기 상태로 월동하였는데, 6%의 생존율을 보이며 이듬해 4월말 우화하였다. 10월 23일에 사육이 시작된 집단은 노숙유충태로 월동하였는데, 이듬해 4월말 용화하여, 5월 초중순에 2%의 최종 생존율을 보이며 우화하였다. 한편 실내에서 사육되어 5령까지 발육된 유충들을 11월과 2월 사이에 야외로 옮겨 사육하였을 때, 생존하는 개체들은 발견하지 못하였다. 항온조건 (25℃, 15L:9D)에서 갓 산란된 알을 11월과 12월 중에 야외로 옮겨 유지하였을 때, 월동하여 부화하는 알은 발견되지 않았다. 또 항온조건에서 갓 우화한 성충들을 11월과 12월 중 야외로 옮겨 사육하였을 때, 모두 사망하였다. 이 결과로 팥나방은 한국의 수원지방에서 10월 중 부화한 유충들이 유충과 번데기로 월동할 수 있는 것으로 추정되었다.

본 연구는 빛공해의 유형인 야간 천명현상의 변화를 분석하고 결과를 제시하는 것을 주된 목적으로 한다. 이를 위해 1992년과 2012년 지표에서 방출된 야외 인공조명을 촬영한 Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) 영상과 읍·면·동 행정경계 지도를 활용하였다. 본 연구에 따르면 지난 20여 년 동안 전체 국토의 약 82% 지역에서 야간 천명현상 수준이 증가했고, 약 10% 지역에서 야외 인공조명도가 감소한 것으로 밝혀졌다. DMSP OLS 영상의 최대 화소값으로 대표되는 심각한 수준의 빛공해를 경험하는 것으로 추정된 읍·면·동은 1992년에 전체의 약 6%에 불과했으나, 2012년에는 약 38%로 증가했다. 이와 같이 야간 천명현상의 증가로 인해 발생할 수 있는 부정적 영향을 최소화하기 위해 빛공해 저감대책마련이 시급하고, 이와 함께 공간역학 측면에서 인간 질병 또는 건강과의 상관성에 관한 연구도 필요할 것이다. 이러한 연구를 위해 DMSP OLS와 같은 인공위성 영상은 지역 또는 국가 전체의 야간 천명현상 수준으로 대변되는 빛공해 수준에 대한 기초자료로서 유용하게 활용될 것으로 기대된다.

본 연구는 전라북도에 위치한 박물관 중 대지면적 10,000㎡이상, 연 관람인원 50,000명 이상인 국·공·사립 박물관 6개관을 대상으로 옥외공간 조경시설의 현황을 현지 조사하여 옥외공간의 조경시설 특성을 파악하고 실제 이용자들에게 설문조사를 통하여 선호도 및 만족도를 통해 문제점을 분석하고자 한다. 이는 향후 박물관의 옥외공간 조경시설을 계획 및 설계하고자 하는데 필요한 기초자료로 활용하는 데에 목적이 있다. 본 연구에서 도출된 조경시설 선호도 분석 결과, 휴게시설은 벤치를, 조경식물은 유실수·조경수를, 수경시설은 분수형을, 편익시설은 옥외화장실을 선호하였다. 전체 만족도에 영향을 준 조경시설은 조경식물, 수경시설, 안내시설, 조명시설, 편익시설의 순서로 나타났다. 옥외 조경시설의 이용활성화를 위해서 지속적이고 체계적인 유지관리 대책이 요구된다. 옥외공간 프로그램 중 체험 프로그램의 이용만족도가 높았으며 프로그램 참여시기는 봄을 선호하였다. 옥외공간 프로그램의 전체적인 만족도는 보통수준이었다. 옥외공간 프로그램 활성화를 위해서는 구체적이고 다양한 프로그램이 요구되며 이를 시행하기 위해서는 지역 자원봉사자 및 해설가를 배치해야 한다고 사료된다.

환경오염 및 자원고갈과 더불어 유기화합물에 의한 신종 질환 발생 등 사회 ․ 환경적 문제 해결을 위해 우리나라를 비롯한 해외 선진국들은 자국의 실정에 적합한 환경 친화적 건축의 기준을 제시하고 있다. 최근 전국적인 주택보급사업 등의 영향으로 인한 신축학교의 증가 및 민간투자사업 (BTL)선정 시, 각 시 ․ 도교육청이 녹색건축물 인증 획득을 의무화한 영향으로 인증제도는 빠른 보급 및 정착을 보여 주고 있다. 학교시설의 환경 친화적 계획은 미래 사회의 원 동력이 될 학생들을 위한 실제적인 실외 건강환경 개선뿐 아니라, 환경 및 에너지 절약의 중요성을 학생들에게 자연 스럽게 노출시킴으로써 교육적 효과를 유발할 수 있는 특성 을 가지고 있다. 이에 따라 학교시설은 학생들의 실질적 체 험을 통해 친환경 개념의 중요성을 전달하는 매개체로서의 역할을 수행하게 되므로, 단순히 인증 획득을 목적으로 하 는 최소조건의 친환경 계획은 이를 접하는 학생들에게 오히 려 '녹색 건축'에 대한 그릇된 인식을 심어줄 수 있다. 녹색 건축 인증 평가항목 중 생태환경 부분에서 외부를 평가하는 항목은 존재하였지만 평가항목 중 학생들의 실외 건강환경 개선에 대한 인증평가 기준이 없는 실정이다. 이에 본 연구 는 국내 · 외 녹색건축 인증 기준을 비교 분석하고, 이론적 고찰을 통해 새로운 평가지표인 실외 건강지표에 대한 항목 을 도출하여 국내에 인증 / 비인증 학교시설를 대상으로 조 사분석 및 평가하여 녹색건축 인증기준의 기초자료로 제시 하고자 하였다. 실외 건강지표는 크게 열적 쾌적성 지표, 음이온, 녹지의 양을 각각 선정하였다. 이중 평균복사온도, 착의량, 대사량, 기류 등을 고려하여 열적 쾌적성 지표 중 UTCI, PMV, WBGT를 측정하였다. 녹지의 양은 녹피율과 녹지용적계수 를 각각 고려하였다. 연구대상지는 인천광역시 남구 및 남동구의 학교시설 중 녹색건축 인증을 받은 학교와 인천광역시 녹지보전 및 녹화 추진사업에서 선정된 학교시설을 대상으로 토지피복현황 이 같은 학교들을 선정하였다. 선정된 연구대상지를 녹색건 축 인증기준의 생태환경부문 평가를 실시하여 점수분포에 따라 유형Ⅰ, 유형Ⅱ, 유형Ⅲ으로 분류하였다. 조사기간은 열섬현상과 열적 스트레스가 가장 심한 여름으로 선정하였 으며, 장마기간이 지난 후인 7월 29일 ~ 8월 18일까지 실시 하였다. 측정지점은 토지피복현황에 따라 녹지, 수면, 건폐 지, 포장지, 운동장으로 나누었으며, 본 연구에서 선정된 학 교는 학교측의 요구로 인해 실제 학교명을 명시하지 않고 기호로 설정하였다. 학교별 기상특성의 경우 모든 학교에서 큰 유의차를 보이 지 않았으며, 유형Ⅰ C학교 운동장의 경우 에폭시 포장으 로, G학교 운동장의 경우 인조잔디로 조성되어있었다. C학 교 건폐지의 경우 벽면녹화 조성에 따라 다른 학교의 건폐 지 보다 쾌적할 것으로 예상되었다. 유형Ⅰ의 녹지면적 및 녹지량은 유형Ⅰ > 유형Ⅱ > 유형Ⅲ 순으로 높게 나타났다. 토지피복현황별 열적 쾌적성 특성은 다음과 같다. 첫째, 녹지의 경우 UTCI 지표는 유형Ⅰ > 유형Ⅱ > 유형Ⅲ 순으 로 쾌적하였으며, PMV 지표도 UTCI 지표와 유사한 수준 이었다. WBGT 지표의 경우 유형Ⅲ에서 10시 이후 부터 옥외활동이 제한되는 결과가 나타났으며, 학교간 비교분석 결과도 유형Ⅲ에서 유의차가 나타나 가장 불쾌적할 것으로 예상되었다. 둘째, 수면의 경우 UTCI 지표는 유형Ⅰ의 C학 교가 가장 일반적인 열 스트레스의 수치로 나타나 다소 쾌 적한 수준이었으며, 유형Ⅲ에서 매우 강한 열스트레스 이상 의 수치로 분석되어 다소 불쾌적한 것으로 사료되었다. PMV 지표의 경우도 유형Ⅲ에서 9시부터 불만족율 100% 의 수치가 나타나 매우 불쾌적한 상태이었다. WBGT 지표 결과 유형Ⅰ의 G학교와 유형Ⅲ에서 9시 이후 부터 옥외활 동이 제한되는 수치가 나타났으며, 학교간 비교 분석 결과 유형Ⅲ에서 유의차가 나타나 수면에서도 유형Ⅲ이 불쾌적 한 것으로 판단되었다. 셋째, 건폐지에서 UTCI, PMV, WBGT 지표 결과 유형Ⅰ의 C학교가 벽면녹화 조성으로 인해 다른 학교들과 유의차가 나타나 매우 쾌적한 것으로 판단되었다. 넷째, 포장지의 경우 UTCI, PMV 지표에서 모 든 유형의 학교간 유의차가 나타나지 않아 매우 불쾌적할 것으로 예상되었다. 다섯째, 운동장은 포장지와 유의한 수 준이었으며, 학교간 비교 분석 결과 유형Ⅱ의 M학교에서 유의차가 나타나 매우 쾌적할 것으로 예상되었다. 토지피복현황별 음이온 분포 특성은 다음과 같다. 첫째, 녹지의 경우 유형Ⅲ에서 음이온 농도가 낮게 분포되는 결과 가 나타났으며, 학교간 비교 분석 결과 유형Ⅰ > 유형Ⅱ > 유형Ⅲ 순이었다. 둘째, 수면의 경우 학교간 비교분석 결 과 녹지와 일치하는 결과가 나타났다. 셋째, 건폐지의 경우 유형Ⅰ C학교의 음이온 농도가 높게 분포되는 결과가 나타 났으며, 학교간 비교분석 결과 유형Ⅰ C학교에서 유의차가 나타났다. 넷째, 포장지의 경우 학교간 비교 분석 결과 유의 차가 없었다. 다섯째, 운동장의 경우 유형Ⅲ 의 음이온 농도 가 낮게 분포되는 결과가 나타났으며, 학교간 비교 분석 결 과 유형Ⅲ에서 유의차가 나타났다. 기상 및 녹지, 열적 쾌적성, 음이온 분포 상관분석 결과 열쾌적 지표인 UTCI, PMV, WBGT 모두 일사, 흑구온도와 정의 상관관계를, 음이온, 녹피율, 녹지용적계수와는 부의 상관성이 나타나 음이온 및 녹피율, 녹지용적계수가 감소할 수록 열쾌적 지표의 수치가 높아져 불쾌적할 것으로 판단되 었다.

Personal or population exposure to hazardous air pollutants has often been assessed by time-weighted average model with combining concentrations of indoor environments and time-activity pattern, which were mainly a single measurement. However, daily levels of air pollutants in indoor environments may greatly be changed because of source emission, ventilation, decay rate and so on. Subsequently exposure by a single measurement in indoor environments could not be assessed properly. In this study, we measured the consecutive 21 daily indoor and outdoor measurements of nitrogen dioxide (NO₂) with 37 houses and 19 shops such as restaurants and coffee shops beside street by using of passive samplers. Considering that average concentration during 21 days was true value, paired t-test was conducted. Daily variations of NO₂ in houses with constant or low emission source were different from those in restaurants with irregular or high emission source. These results can be explained that the NO₂ emission of indoor sources could affect the validity of measurement periods.
