This research examines the historic preservation of Korean modern architecture by applying Kenneth Frampton(1930-)'s concept of critical regionalism. It explores the representative Korean modern architect Gil-ryong Park (1898-1943) and two of his buildings: the Hwashin Department Store (1935) and the No-soo Park house (1937-1938). The former was in the hot spot on the preservation. There were plans to preserve this building but that it ended up being demolished in 1987. The latter building, however, has been preserved and is currently being used as a museum. These two Korean modern buildings are explored through the frame of Kenneth Frampton's critical regionalism, in particular focusing on three important concepts: "dialectical expression," "place-form," and "sustainability." In this sense, this research will provide pioneering research in understanding the preservation of Korean modern architecture through a representative Western modern theory. In the early $20^{th}$ century, Korean modern architecture, which was built during the Japanese colonial period (1910-1945), could be interpreted as critical regionalism because it represented a dialog between the West and the East, in particular between Western modernism, Japanese modernity, and Korean tradition in the East Asian context. Understanding Korean modernism in this context of a cross-cultural perspective enables scholars to define both the origins and uniqueness of Korean modern architecture.

The purpose of this study is to provide information needed to the construction of the co-housing in the urban area. This study focused on the characteristics of co-housing in its planning process of private house & common space; 'economy', 'creativity' & 'sociality'. The object of this study is co-housing in 'Seongmi-san Village' in Seoul, which was built by a coordination company with residents' participation. The methods are investigating interview materials, floor plans of 9 households, & common space plans produced in the coordination process from the basic plan of private house & common space to the final plan. The results are as follows. 1) The size and plan of private house differed from each other. The water pipe location differed from each floor, so that there were difficulties in construction. In conclusion, these made no 'economy', but brought high 'creativity'. 2) The 'sociality' would be estimated as high because there were various types of resident participation; resident interviews on the planning, workshops for private housing plan, and workshops for common space.

Purpose: House dust mite (HDM) has been suggested to be the most important aeroallergen responsible for atopic asthma in Korea. We aimed to investigate that specific IgE antibodies to HDM and other common indoor aeroallergens contribute differently to total serum IgE and show different relationships with longitudinal fractional exhaled nitric oxide (FeNO) measurements in Korean atopic asthmatic patients. Methods: A total of 193 children aged 8 to 16 years with intermittent or mild persistent atopic asthma were recruited. Sera were assayed for total IgE and specific IgE antibodies to HDM and other common indoor allergens. FeNO was serially measured 10 times or more over 2 years when subjects were not receiving controller medications. Results: In 152 children who completed the study, IgE antibodies to specific HDM were more prevalent than those to other common indoor aeroallergens. In addition, IgE antibody titers to HDM were the strongest contributor to total IgE increases. Furthermore, only HDM-specific IgE antibody titer significantly correlated with maximum FeNO (r=0.21, P=0.029) and the rate of FeNO higher than 21 parts per billion (ppb) (r=0.30, P=0.002). Eight patients (5%) were found to have maximum FeNO of 21 ppb or less, suggesting the presence of a low FeNO phenotype among atopic asthmatic patients. Conclusion: The quantity of HDM-specific IgE antibody provides a possible explanation for increases of total IgE and significantly correlates with the amount and frequency of FeNO increases in Korean atopic asthmatic patients.

Farmers are generally expressed to pesticides through mixing loding, application activity and harvesting of crop after application of pesticides. The present work investigated the exposure and risk of furathiocarb to workers when harvesting of cucumber was carried out in green house after application of furathiocarb EC. Glove was used for the hand exposure assessment, socks for foot and dermal patches for the other parts of body. Personal air monitor equipped with a XAD-2 resin was used for the respiratory exposure assessment. During the harvest of cucumber in green house, the initial rate of potential dermal exposure (Day 1) for methidathion was 1.3 mg/hr. The major exposure parts were hand $(78\~83\%),\;thigh\;(5\~7\%)$ and arms $(6\~9\%)$ during 3 days' harvest. No exposure was detected from the respiratory monitoring. For risk assessment, the potential dermal exposure (PDE), the absorbable quantity of exposure (AQE) and the margin of safety (MOS) and margin of exposure (MOE) were calculated. In risk assessment of harvester exposure for 7days, all MOS was > 1 and MOE was > 100 indicating that possibility of risk was little.

For the comfortable housing life, an urban environment should give comfort and pleasantness to people living in house and in city. There are lots of environmental conditions in city affecting house and life and most of all the noise pollution have been become factor that makes people's life hard without need to say. Recently researches have been performed to create comfortable urban environment and a study on the evaluation of urban environmental sounds is now undergoing. This study aimed to analyse the subjective characteristics through the subjective evaluation to the sounds measured with physical parameters and eventually to find out evaluation method for urban environmental sounds. Vocabularies applied to previous studies were used for the subjective evaluation and sound sources recorded in specific places were presented with picture at the same time.

Korea is facing various social problems including single elderly household, increase in the number of disabled people and poverty rate and a difference in the proportion of males to females between urban areas and rural areas along with the advent of rapid aging society. Especially, the ratio of poor households in rural areas residing in housing which falls below the minimum housing level and most of them are in the dead zone of housing welfare. In addition, if it is impossible for them to move (relocate) to new housing, the house remodeling is the only measure for improving their housing welfare. However, we don't have enough prior relevant academic and practical experience, and house remodeling requires a series of process including prior planning construction and post-occupancy evaluation, but almost no fundamental research that provides relevant insight has been carried out. Therefore, the purpose of this study is to describe all field situations that occur in the whole customized house remodeling process for disabled female senior citizens living alone in a rural area. The remodeling process was classified into initial planning stage, field verification and adjustment stage and construction stage as the method to participate in the field directly, and any change in the remodeling plan and its causes at each stage were analyzed. As a result, some remodeling items were changed from the main viewpoint of participating parties before the beginning of construction and for reasons such as the deterioration level of housing site, limitation in building equipment and rearrangement of housing, etc., and the remodeling method and its details were developed. It was identified that constant change that occurred in the remodeling process resulted from 1) unique poor characteristics of existing housing and 2) physical condition of residents and their unique lifestyle characteristics that were two aspects required to be emphasized by customized remodeling.

In swine house, dust generation comes from various sources and is known to be harmful both for the animals and the farmers because the dust contains biological and gaseous matters. When farmers are constantly exposed to the dusts, they can suffer chronic or acute respiratory symptoms and have high probability of manifesting various diseases. To address this problem, understanding of the mechanism of dust generation is very important. In this paper, the dust concentration of inhalable, respirable, TSP and $PM_{10}$ were monitored and analyzed according to the pig-activity level, ventilation quantity and feeding method in fattening pig house. From the measured results, in case of the concentration of TSP, an inverse-linear relation with ventilation rate ($R^2=0.88$) and linear relation with the installation height of feed supply pipe ($R^2=0.73$) were determined. However in case of the concentration of $PM_{10}$, no particular relationship with the variables was observed. Using the concentration of inhalable and respirable dust based on the pig-activity level, multi-variate regression analysis was conducted and results have shown that the movement of pigs can contribute to the dust generation (p＜0.05, $R^2=0.71$, 0.61). The relationship determined between dust generation and environmental variables investigated in this study is very significant and useful in conducting dust-reduction researches.

SULEV (Super Ultra Low Emission Vehicle) which is one of the emission standards in Fleet Average System introduced to Korea from 2009 is known as the most severe standard to achieve with internal combustion engine. Considering low sales volume of hybrid vehicles in Korea, vehicle manufacturers are required to develop SULEV technologies for conventional gasoline and LPG vehicles to meet the future Fleet Average standard. In this study, the comparison of emissions has been made between SULEV developed and ULEV LPG vehicles mainly produced in this time. To estimate the emission reduction of SULEV vehicles, CVS-75 and NIER test modes have been used. CVS-75 has been used for emission certification of gasoline and LPG vehicles. NIER modes cover various average vehicle speed and reflect Korean real driving patterns better than CVS-75. The test results show that SULEV LPG vehicles have very high potential to reduce $NO_x$ in regulated emissions, $N_2O$ in green house gases and toluene in VOCs. However, SULEV LPG vehicles don't affect much on the reduction of CO and total green house gases.

질산태 질소 수준이 $55{\sim}306mg\;kg^{-1}$인 6개 시설재배 토양에 대하여 시비수준을 무비구와 표준시비구로 구분하여 토마토의 생산력과 엽록소 측정치(SPAD, Minolta 502)의 상호관계를 조사하고 덧거름 시용량 결정을 위한 식물체 검정법의 활용 가능성을 비교 검토하였다. 토마토 잎의 엽록소 측정치는 단위 엽면적 당 질소 흡수량과 유의성 있는 정의 상관관계를 보여 식물체의 질소 영양진단의 지표로 활용 가능한 것으로 확인되었다. 토마토 재배기간 동안 엽록소 측정치는 정식후 45일째 15매엽에서 최대를 보인후 감소되는 경향을 보였으며 시비수준과 질산태 질소 함량에 관계없이 동일한 경향이었다. 이러한 결과로부터 토마토의 질소 영양진단을 위한 기준시기와 기준엽위는 정식후 45일 이전과 15매엽 이하가 효율적일 것으로 생각되었다. 정식후 40일째 14매엽의 엽록소 측정치는 토양의 질산태 질소 함량및 무비구 토마토의 건물중 그리고 무비구 토마토에 의한 질소흡수량과 유의성 있는 정의 상관을 보이며 2차함수의 곡선적 관계를 나타냈다. 무비구 토마토의 최대 건물중과 최대 질소 흡수량으로 추정한 엽록소 측정치는 57.1로 동일하게 평가되었다. 따라서 토마토 정식후 40일째 엽록소 측정치는 질소 웃거름 시비량을 결정하기 위한 식물체 검정법으로 활용 가능한 것으로 생각되었다.
