12세로 추정된 시설아동의 2년간 지속된 구토행위를 행동치료 방법을 사용하여 치료하였다. 이 아동의 구토행위 형태는 바닥에 음식을 토해 낸 후 $2{\sim}3$ 차례에 걸쳐 토한 음식을 다시 먹는 것이었다. 치료 방법으로 일단 토해 낸 음식을 다시 먹지 못하도록 하기 위해 음식을 토할 때마다 즉시 토한 음식을 치웠다. 일단 위에 들어간 음식을 역류시켜 바닥에 토하지는 않았지만 입안에서 씹을때는 입을 강제로 벌려 입안의 음식물을 제거하였다. 치료는 약 3주간 지속되었는데 식사 후 2시간 30분동안 치료전에는 평균 46회($범위=30{\sim}62회$)토했고 치료 후에는 평균 1.12회($범위=0{\sim}10회$)로 감소하였다. 치료 종료 후 10개월이 지난 뒤에도 아동의 구토행위는 재발되지 않았다. 따라서 토하는 행위를 강화시키는 요인인 '토해낸 음식을 다시 먹는 기회'를 박탈한 본 연구의 치료방법은 구토행위의 치료에 매우 효과가 높은 것으로 나타났다.

personal nitrogen dioxide(NO$_2$) exposures for 31 professional drivers were measured using passive sampler and time activity diary in Asan and Chunan area, and were estimated using time-weighted average model. Mean concentrations of driver’s indoor and outdoor were 24.7$\pm$10.7 ppb and 23.3$\pm$8.3 ppb, respectively with indoor/outdoor of 1.1. Mean personal NO$_2$ exposure was 30.3$\pm$9.7 ppb. Personal NO$_2$ exposures were strongly correlated with indoor car NO$_2$ levels ($R^2$=0.80) rather than residential indoor NO$_2$ level ($R^2$=0.55). and outdoor NO$_2$ level ($R^2$=0.50). The driver’s NO$_2$ exposure using LP-gas with 24.4$\pm$8.0 ppb were statistically different from those using diesel with 36.3$\pm$14.1 ppb(p<0.01). The effect of driver’s smoking for personal NO$_2$ exposure was not found. It was considered that the main NO$_2$in driver is transportation. Since drivers mostly spent their times in indoor and inside car, time-weighted average model could be used to estimated personal NO$_2$ exposure using time activity diary, Though we did not measure all microenvironments, the estimated personal NO$_2$ exposures with 26.9$\pm$10.2 ppb were statistically correlated with measured personal NO $_2$ exposures30.3$\pm$9.7 ppb ($R^2$=0.89). The mean and standard deviation of personal NO$_2$ exposure using Mote-Carlo simulation were 26.6$\pm$7.2 ppb.

In this research, the connectivity status between natural environment (forests and rivers) and urban parks in view of ecological networks in a city is evaluated and on the basis of these evaluation results, a future connectivity enhancing recommendations are suggested. As a result, the 96.8% of the connectivity role of the neighborhood parks were core or connected parks and as in terms of the ecological pattern on the outer park, 84.1% of the case neighborhood parks were connected to the ecological element at least one side. Therefore, it can be expected to play a role as corridor that enables the direct connection with the natural environment if the connection plan is well established. As a result of connectivity evaluation of the parks, inside of the parks had low ecological element overall and had low connectivity, outside of the parks had 1.5 times more of low connectivity parks than high connectivity parks, and had similar disconnections such as facilities(fence, soundproof walls, breast walls, etc.), developments(roads, apartment complexes, industrial complexes, etc.), or poor greens regardless of the neighborhood with the ecological elements. To increase the connectivity of ecological network, the cities already built shall secure primarily green territory where can connect with the isolated park due to the surrounding with the developing areas and when planning for new cities or residential complexes, it shall establish a connection plan with the nearby at the beginning.

The purpose of this study is on identifying the function of ground temperature arrangement of village grove. Case study was accomplished at Hacho village grove in Jinan-gun, Jeonbuk province. Hacho village grove was the largest grove of all and most formal grove in Jinan region. So ground temperature of outside and inside of Hacho village grove were measured from March to October in 2001. And comparative review about difference between outside and inside of village grove was accomplished. Our ancestors, in spite of orient and occident, have made a settlement in consideration of climatic conditions. We have to team from past pattern and add modern scientific technology. So traditional wisdom and wise planning process must be considered in order to create qualitative residential environment in present through natural elements. It is identified that in winter, the inner side ground temperature is higher than outside one of that and in summer, in contrary, the inner side one of that is lower than outside one of that. So it is identified that Macho village grove breaks winds and reduce the heating energy in winter, it reduces ground temperature and reduces cooling energy very well in summer. It is identified that village grove reduce ground temperature in summer better than any other season. It is identified that in summer, the effect of maintaining constant temperature is also better than my other season. So it is identified that village grove stabilize most changeable outside temperature in inside of that.

To analyze the space features of small-sized detached houses, this study has compared the floor plan types of detached houses and apartments. Currently small-sized detached houses are popular in Korea. The comparative analysis was focused on common residential patterns and the apartment plan. The results of space syntax were summarized as follows: four types of apartments and twelve types of small-sized detached houses were deduced by the relative spatial depth analysis. Among the sixty-seven house samples, only two of them showed the same pattern as those of apartments, which showed that each room of detached houses had distinct difference with those of apartments. According to the integration and control analysis, each space of apartments showed difference within narrow range, while the space of detached housed showed difference within wide range. In addition, the detached houses showed distinct relations between the center of space and the surroundings, and there are distinct differences between the easier layouts for access rooms and difficult ones. Moreover, the living rooms of detached houses somewhat exist under the low integration condition, and they cannot be standardized in the center of house, which are different with those of apartments. The master bedrooms of detached houses exit at the surrounding space same as those of apartments. Nevertheless the toilet is in the master bedroom which made its control lower than those of apartments.

The spatial air pollution distribution of the Ulsan metropolitan region (UMR) was analyzed using monitoring data and high-resolution numerical simulations. A three-year (2011~2014) analysis for the average concentrations from the 13 air quality monitoring sites in the UMR showed that $SO_2$ and $PM_{10}$ levels in industrial regions were much higher than those in other regions, whereas spatial differences of $NO_2$ and CO concentrations were not significant. In particular, elevated $O_3$ concentrations were clearly found at urban sites near petrochemical complex area. Results from high-resolution simulations by CMAQ model performed for four months of 2012 showed large spatial variations in grid-average pollutant concentrations between industrial areas and other areas in the UMR, which displayed significant changes with wind pattern by season. It was noted that the increases of $SO_2$ and $PM_{10}$ levels were limited in costal industrial areas or over the area nearby the sea in all seasons. Modeled $O_3$ concentrations were quite low in industrial areas and main urban roads with large $NO_x$ emissions. However, the model presented that all pollutant concentrations were significantly increased in the urban residential areas near the industrial complexes in summer season with increase of southerly wind.

본 연구에서는 시계열 항공영상을 이용하여 갑천의 토지이용 패턴을 제내지와 제외지로 구분하여 분석하였다. 먼저 제내지에서는 주거지, 도로, 공업지, 공공시설이 도시화 증가항목으로 선정된 반면, 농경지, 산림 그리고 하천은 도시화 감소항목으로 분류되었다. 또한 이러한 증가와 감소항목들이 1988년도를 기점으로 역전되는 경향을 나타내었으며 이를 통해 갑천의 토지이용이 1988년을 기점으로 도시화로 전환되었음을 추정 할 수 있다. 제외지에서는 시간이 경과함에 따라 현하천의 면적이 감소하는 것으로 나타났으며 이는 고수부지, 교량 그리고 보와 같은 도시화를 반영하는 토지이용 항목의 면적이 증가된 것을 의미한다. 또한 수문자료를 고려한 현하천에 대한 수계의 비율은 시간이 경과함에 따라 증가하였다. 전반적으로 볼 때, 항공영상은 하천관리 및 계획에 필요한 토지이용 정보를 구축하는데 유용하게 활용될 수 있으리라 판단된다.
