Thin films of SnO₂, SnO₂-Sb₂O₃ were fabricated by the use of DC sputtering system and electron beam etaporation system. The films were analyzed by means of scanning electron microscopy and Auger electron spectroscopy. The results showed the films to be polycrystalline with an average grain size of 0.6 μ and the relative ratio of Sn and O₂ peaks to be 1.5/1. The investigation of characteristics-of electrical conductivity versus thin film surface temperature showed the oxygen gas to be adsorbed in the temperature range of 230-400℃. Thin films had good sensitivity to acetone, alcohol, SO₂ and propane gas. The optimum thin film surface temperature was found to be about 450℃.

Little research has been done regarding the issues of Ecotourists' behaviour on visiting Eco-tourism sites. Thus, this study investigated how tourist' motivation and expectation of visiting Upo wetland influence their satisfaction and behaviour. The key variables of this study are 1) motivation, satisfaction, expectation, behaviour intention of tourist before/after traveling.the analysis of this study, SPSS 12.0 was used which included was used factor analysis, descriptive analysis and multiple regression analysis.findings of this study suggest as follows. Firstly, although tourists showed their visit expectations for preservation of natural environment and value of high living. They had low intention participation of environmental education programmes. Secondly, tourists' motivation influenced tourists' satisfaction and intention of behaviour in general by visit. Particularly, posttravel survey showed that motivation of learning and enjoying natural environmenthad an impactsatisfaction.Finally, those tourists who had experience of environmental education, and environment tour before the survey showed more satisfaction of tourism. Furthermore, the post survey showed that their experience environmental tour affected their value of benefits of environmental tour as well as environmental preservation and rest.

This study’s purpose lies in investigating the consciousness of the residents in Yangdong Folk Village, Gyeongju City, in accordance with its designation as a world cultural heritage by the United Nations Educational, Scientific and Cultural Organization (UNESCO) and coming up with a direction to reduce negative factors affecting their lives. The result of this study showed that the village had undergone a lot of changes. In particular, tourists’ flurry of visits exceeding the admission capacity of the village, which was not yet prepared to welcome them, was negatively influencing the residents’ lives and the environment. The problem in copper wiring, high concentrations of people in certain locations, and gathering of visitors exceeding its admission capacity in certain time zones brought out serious outcomes including infringement on some residents’ private lives, environmental pollution, and noise. Therefore, a more stable adjustment regarding the village’s transformation into a tourist destination, tourists’ improper behaviors, and the authority’s administration ignorant of its admission capacity is necessary.

음식물의 조리과정에서 발생하는 황화합물의 배출특성연구

조상희,김기현 한국냄새환경학회 2011 실내환경 및 냄새 학회지 Vol.10 No.2

In this study, the emission characteristics of reduced sulfur compounds (RSC) including H2S, CH3SH, DMS and DMDS released via cooking were investigated. Cooking smoke samples were produced by two different cooking methods (fry and steam) and analyzed for direct comparison between three types of food (cabbage, clam and coffee bean). In general, a large quantity of RSC came out from fried foods relative to steamed foods. The conversion of RSC concentration to odor intensity (OI) showed OI values in the range of 2.54∼6.41 for fried foods and 1.23∼3.68 for steamed foods. The results of this study suggest that we need to develop and establish environmentally friendly cooking methods. 본 연구에서는 음식물의 조리 과정에서 발생하는 환원황화합물(Reduced Sulfur Compounds; RSC) 중 지정악취물질에 해당하는 H2S, CH3SH, DMS, DMDS의 배출특성을 조사하였다. 이를 위하여 3가지 식재료(양배추, 조개, 커피)를 분석대상 음식물로 선정하고, 두 가지 방식(구이 및 찜방식)으로 조리하여 조리과정의 매연시료를 채취하였다. 채취한 시료는 TD를 연계한 GC-PFPD로 분석하였다. 검출한계 이하를 보인 성분들을 제외하면, 구이방식으로 조리할 때 찜방식보다 더 많은 황화합물을 배출했다. 이들 농도자료를 악취강도로 환산하면, 구이방식은 2.54∼6.41도, 찜방식은 1.23∼3.68도의 분포를 나타냈다. 이처럼 같은 음식물이라 하더라도 조리방법을 다르게 할 경우, 황화합물의 배출량에 큰 차이를 보였다. 선행연구에서 환원황화합물은 농도대에 따라 독성을 갖고 있음을 확인하였다. 따라서 음식물의 조리와 같은 활동은 생활환경에서 광범위하게 이들 물질에 노출되는 위험이 따르므로, 친환경적인 조리방식에 대한 연구가 필요할 것으로 사료된다.

The objective of the research is to examine level of perceived stress among residents of Daeheung-myeon, Yesan-gun, which is a designated Slow City. For this purpose, the research compares level of stress between residents of the Slow City and urban residents in Daejeon metro city. The research is expected to contribute to justifying designation and management of Slow City and promoting Slow City movement based on widespread understanding of its residents. SPSS 14.0 was used to perform and calculate factor analysis, t-test and two-way ANOVA for statistical analysis. According to the analysis result, residents of a metro city showed higher stress level than Slow City residents. The discrepancy in level of stress varied according to demographic characteristics, which suggests that such properties need to be taken into consideration in providing support and service for Slow City residents.

Little research has been done regarding the issues of Korean nationalisms influence on choosing oversea travel destinations. Thus this study investigated the decision making and effects of oversea travel that was influenced by Korean nationalism. The key variables of this study were 1) Nationalism, 2) Oversea Destinations, 3) Preference, 4) Nation.For the analysis of this study, SPSS 12.0 was conducted, which also included Factor analysis, Descriptive analysis, ANOVA, Cluster analysis, Discriminant analysis, Multidimensional analysis and Regression analysis. The research focused on travel to the United States, Japan, China, Thailand and Vietnam.The findings of study suggests the following. Firstly, there are differences in the perceived feelings and of the nations that were researched. Secondly, there were significant differences among Koreans attitude about nationalism and travel preference in nations as a destination. Finally, the found differences in the level of nationalism and travel preference for selecting a travel destination. This study suggests that research on nationalism and tourism should continued for the development of the tourism industry.

전자선 처리공정 중 첨가제 운전 조건에 따른 질소/황산화물 처리효율 비교 연구

조상희,오용환,손지은,김태훈,김탁현,유승호,서서희,손윤석 한국대기환경학회 2021 한국대기환경학회 학술대회논문집 Vol.2021 No.10

산업시설 배가스 중 고농도의 질소/황산화물을 처리하기 위해서는 대용량의 처리가 가능한 고에너지 분해기술이 필요하다. 가속된 높은 에너지를 지닌 전자들을 이용해 환경오염물질을 처리할 수 있는 전자선 기술은 전자선을 조사하면서 동시에 첨가제 분사 공정을 보조적으로 활용할 경우 오염물질의 처리효율을 향상시키면서 경제성도 확보할 수 있다. 전자선 처리과정 중 수용액 상태의 첨가제 분사는 OH 라디칼을 추가로 생성할 수 있는 공급원이면서 동시에 습식세정 효과를 유도한다. 본 연구에서는 모사 배가스(NO: 250ppm, NO₂: 30 ppm, SO₂: 500 ppm)를 이용한 연속식(20 m³/hr) 전자선 처리과정 중 첨가제 운전 조건(농도, 기액비)에 따른 NOx, SO₂의 처리효율을 비교분석하였다. 이를 위해, 전자선 조사 반응기에 첨가제(NaOH 수용액)를 분사할 수 있는 미세분사 노즐을 설치하고 전자선의 흡수선량, 첨가제의 분사 유량(312, 870, 1,260 mL/min) 및 농도(0.02, 0.2 M)에 따라 NOx, SO₂의 처리효율을 측정하였다. 그 결과, 전자선만 조사하거나 또는 첨가제만 분사하는 공정보다는 전자선+첨가제 동시처리 공정에서 처리효율이 크게 증가하는 양상을 보였다. 또한 첨가제의 유량이 증가하면 SO₂의 처리효율은 최대 25%, NOx의 처리효율은 최대 33%까지 증가하였다. 첨가제의 농도에 따른 처리효율 차이는 분사 유량의 차이에 비해 상대적으로 적은 효과를 나타냈다.
