The purpose of this study is to examine the environment friendliness through the analysis on passive environmental control methods of Korean traditional architecture especially the residences of Joseon Dynasty. As the industrialization progressed, the importance of study in environment issues has increased. This study redefines environmentally friendly architecture and the definition results from the study of the environmental control methods of the traditional architecture formed over the long periods of time. The research focused on the Joseon Dynasty since the existing architecture was mostly formed after the mid Joseon Dynasty. The preliminary method of study was literature analyses of the environmental friendliness and environmental control methods of the korean traditional architecture. The study explores the supplementary passive environmental methods to control the environment. In addition, the supplemental analysis is set up with a basic model of traditional architecture and analyzed the light and heat environment side of passive environmental control methods through simulation and proved the environment friendliness of passive environmental control method of traditional architecture through scientific verification. When using the supplemented eave, the inflow of direct sunlight decreased from 14.15% to 10.05%, so that it was possible to maintain a comfortable environment in thermal environment and it showed a uniform illuminance distribution of approximately 150lux in the indoor illumination analysis and proved to create a pleasant light environment. This study could be the practical reference data for environmentally friendly architecture with using passive environmental control methods which may be built in the future.

( Yu-chi Tsai ),( Chen-yu Cheng ),( Jih-tay Hsu ),( Shih-torng Dnig ),( Ta-te Lin ) 한국농업기계학회 2018 한국농업기계학회 학술발표논문집 Vol.23 No.1

In tropical and subtropical regions with high temperature and humidity conditions, one of the problems in dairy farm management is the effect of heat stress on animal productivity. Due to this problem, the utilization of an automatic environmental monitoring system for cooling, labor-saving and heat stress reduction is necessary. In this study, an environmental monitoring and automatic cooling system based on an embedded system for dairy farms was designed. The system aims to regulate the environmental condition by means of direct feedback depending on the monitoring of heat stress index (HSI) augmented by dairy cow drinking behavior. The system is composed of two sub-systems: data acquisition and environmental control. The data acquisition module collects images, temperature and humidity data. The cooling system is controlled based on the real-time environmental data, and the historical data are recorded and uploaded to the server for display and analysis. The data are analyzed on the environmental monitoring panel on the farm and on the website, which can be remotely accessed. The control parameters are adjusted using the image results from the dairy cow drinking behavior with a fixed time interval. The results of the conducted experiments show that there is labor saving improvement and an increment in milk production compared to the same period in the previous year when the system was not installed. The automatic environmental monitoring cooling system exhibits high efficiency and can perform real-time control and self-adjustment. The system can be used for fully automated dairy cow system application, as well as dairy cow behavior analysis through both environmental and image information.

최종민(Jong-min Choe) 한국경영과학회 2018 經營 科學 Vol.35 No.2

The concrete relationships among external environmental factors, environmental strategy, the usage patterns of environmental management control systems (EMCSs), the types of corporate environmental innovations, and innovation openness have not been empirically examined in prior research. This study empirically investigated these relationships to identify and suggest the ways for increasing the degrees of environmental innovations through the use of EMCSs under adopted environmental strategy. The empirical data in this study were collected through the post-survey. 96 valid survey data were finally collected. The results of this study showed that ecological uncertainty and stake-holders’ pressures have a positive impact on the adoptions of ecological efficiency strategy and proactive environmental strategy. It was also observed that a proactive environmental strategy only positively influences the diagnostic and interactive usage of EMCSs. In the results of the effects of usage patterns of EMCSs on the types of innovation, it was showed that the EMCSs’ diagnostic use positively influences the levels of environmental-friendly product innovation, and interactive usage has a positive effect on the degrees of process innovation. According to the results, it was indicated that innovation openness has a moderating impact on the relationship between EMCSs’ diagnostic usage and environmental-friendly product innovation. Thus, it was demonstrated that under high levels of innovation openness, a high degree of environmental-friendly innovation can be achieved through the use of EMCSs. Based on these results, it is concluded that different usage types of EMCSs activate different forms of an environmental-friendly innovation in manufacturing firms. It is also broadly proposed that there exist influence relationships among the kinds of environmental strategy of a firm, the usage forms of EMCSs, and the different types of environmental-friendly innovations.

Lee, Jong-Suk The Society of Air-Conditioning and Refrigerating 2000 International Journal Of Air-Conditioning and Refr Vol.8 No.1

Environmental control facilities are used to simulate an environment or combination of environments under which many kinds of research and tests can be performed. The design of the control system to maintain desired environmental conditions is essential to proper operation of the facility. A simulation model of the facility has been developed by analyzing each component of the system thermodynamically. with necessary properties and heat transfer relations. Using the system simulation model, the required characteristics of the control system has been investigated. PI controller is considered as the most probable controller for this kind of the facility, and electric heater power is shown as the proper manipulated variable for temperature control.

일본(日本)에서 계류변(溪流邊)의 환경복원(環境復元) 발전전략(發展戰略)(V) -한국적(韓國的) 적용(適用)을 중심(中心)으로-

박재현,우보명,권태호,이헌호,Park, Jae-Hyeon,Woo, Bo-Myeong,Kwon, Tae-Ho,Lee, Heon-Ho 한국환경복원기술학회 2001 한국환경복원기술학회지 Vol.4 No.1

The objective of this study was to introduce the current status and development strategy for the environmental restoration of stream side in Japan, and to consider the methodology which could be effectively applied to the environmental restoration of stream side in Korea. 1. We should establish a new paradigm of forest conservation and erosion control which can emphasize the restoration of the stream side ecosystem and reduce soil movement in the areas. Also, in the past, the objective of forest conservation and erosion control was to fix soil by constructing permanent structures. The direction of future forest conservation and erosion control needs to be new forest conservation and erosion control technology to prevent large scale soil movement but allow small scale soil movement to conserve sound ecosystem and biotic habitats. 2. In the past, the goal of forest conservation and erosion control planning was to fix the amount of soil movement by constructing permanent facilities. Forest conservation and erosion control planning in the future needs to change the techniques which could prevent soil movement from large scale of soil disasters, but allow soil movement effectively to a small and middle scale's soil movement. Also, it is considered to change erosion control dams from non passing type to passing type. 3. In the point of ecological conservation aspects, we should evaluate the effects of new forest conservation and erosion control methods which are emphasized on the restoration of the stream side ecosystem. Also, forest conservation and erosion control construction projects for restoring stream and river ecosystem should be planned for perfectly restorating their ecosystems by the way of sustainable maintenance and management. 4. The restoration direction of stream and river ecosystems needs to be restoring the diversity of small geographies such as waterway, shoal and puddles rather than flattening stream bed. And the restoration of the stream side ecosystem should provide continuity of the stream side environment which allows desirable biological habitats, and environmentally sound facilities to harmonize with the environment.

김용찬(Yong-Chan Kim),손해영(Haeyoung Shon),심홍진(Hongjin Shim),임지영(Ji Young Lim) 사이버커뮤니케이션학회 2012 사이버 커뮤니케이션 학보 Vol.29 No.2

본 연구의 목적은 스마트폰과 SNS이용이 개인들의 ‘지각된 환경통제감’에 어떤 영향을 미치는지를 살펴보는 것이다. 즉, 스마트폰과 SNS 이용이 세 가지 환경(사회환경, 미디어 환경, 공간환경)에 어떤 영향을 주고 있는지를 살펴보고, 스마트폰/SNS 이용과 환경에 대한 개인 통제감 사이의 관계에서 환경에 대한 적극적 개입 성향 변인들(혁신성, 행동활성화체계, 내적통제신념)의 조절효과를 검증하는 것이다. 본 연구를 위해 서울시와 수도권에 거주하는 18세에서 49세까지의 성인 1502명을 대상으로 하는 면접 설문 조사 데이터를 사용하였다. 본 연구의 주요결과는 다음과 같다. 첫째, 스마트폰과 SNS의 이용 여부 자체는 세 가지 종류의 환경 통제감(사회환경, 미디어 환경, 공간환경)에 거의 영향을 끼치지 않거나, 영향이 있더라도 그 정도가 매우 미미한 것으로 드러났다. 둘째, 스마트폰과 SNS 이용이 환경 통제감에 미치는 영향은 개인들이 기존에 가지고 있던 환경 개입 성향(개혁성, 행동활성화체계, 내적통제신념)에 의해 조절되는 것으로 나타났다. 스마트폰의 경우 환경 개입 성향이 낮은 사람들일수록 스마트폰 이용과 환경 통제감 사이에 정적인 결과가 나타난 반면, 환경 개입 성향이 높은 사람들 사이에서는 스마트폰 이용자와 비이용자들간 환경통제감 인식 정도에 통계적 차이가 나타나지 않았다. 또한 SNS 이용의 경우엔 환경 개입 성향이 높을수록 SNS 이용이 환경 통제감과 정적 관계를 보인 반면, 환경 개입 성향이 낮은 사람들 사이에선 SNS 이용과 환경 통제감 사이에 부적인 관계가 나타났다. The purpose of the current study was to assess the effects of SNS use and smartphpne use on individuals’ perceived controllability over three aspects of their environments (‘environmental controllability’) ?social, media, and spatial environments. We also aimed to test whether there is a moderating effect of what we define as individual’s ‘active intervention in environments’ (behavioral approach system, innovativeness, and internal locus of control) on the relationships between smartphone use (and SNS use) and perceived environmental controllability. We collected survey data by in-person survey from about 1500 individuals who lived in the Greater Seoul area between October and November, 2010. We found that the relationships between smartphone use (and SNS use) and perceived environmental controllability were negligible. However, the relationships between smartphone use and SNS use were moderated by the variables of environmental intervention (especially innovativeness and BAS). The relationship between smartphone use and environmental controllability was stronger among individuals with low level innovativeness and high BAS. On the other hand, the relationship between SNS use and environmental controllability was stronger among individuals with high level innovativeness and high BAS. Our interpretations of these results and discussions about limitations and future study topics were provided.

소매상황에서 지각된 통제가 소비자의 감정적 반응 및 재방문의도에 미치는 영향

차태훈(Tai Hoon Cha),이상현(Sang Hyun Lee),전승우(Seung Woo Chun) 한국마케팅학회 2008 마케팅연구 Vol.23 No.2

이 연구의 목적은 소매상황에서 고객이 느끼는 지각된 통제(perceived control)가 그 고객의 소매점에서의 소매행위와 관련된 여러 가지 반응들(감정적 반응, 재방문의도, 구전의도, 자신감)에 미치는 영향을 조사하는 것이다. 이 주제는 소비자/소매연구에서 활발히 연구되었으나, 대부분 서양인의 시각에서 서양 소비자들을 중심으로 이루어졌다. 그 결과, 고객들의 지각된 통제의 수준이 높으면 높을수록(고통제), 고객들이 느끼는 긍정적 반응의 크기가 커지고, 통제수준이 낮으면 낮을수록(저통제), 고객들의 반응은 부정적이 된다고 알려졌다. 이 연구에서는 동양인들의 통제에 대한 기존 연구결과들을 바탕으로 소매점에서 한국인들은 고통제 상황보다 저통제 상황에서 더 긍정적인 반응들을 보일 것이라는, 기존의 마케팅 연구결과들과는 상반된 가설들을 수립하고 실증하였다. 이 실험은 두 가지 다른 형태들로 이루어 졌는데, 하나는 MP3 매장에서 점원의 고객응대 과정에서 적극적인 정도를 다르게 하여 인지적 통제수준을 조작하는 방식이었고, 다른 하나는 중식당에서 선택메뉴를 일품요리와 세트메뉴로 구분하여 의사결정 통제수준을 조작하는 방식이었다. 이 두 실험 결과, 모두 예상과 같이, 한국인들은 저통제 상황에서 고통제 상황보다 감정적 반응, 재방문의도, 구전의도, 자신감에 모두 긍정적인 반응을 보였다. The purpose of this study is to investigate the influences of perceived control on customers` emotional response, re-patronage intention, positive word-of-mouth intention, and confidence level. This issue has been investigated extensively in consumer research. However, most of the research has been done by using only Westerners as research subjects. The results have been interpreted based on the Westerner`s point of view. The studies have continuously acknowledged that consumers who feel higher perceived control in a retail setting show more positive responses than do those who feel lower perceived control. Being different from the previous research on this issue, we employed Koreans as our research subjects. Based on the previous research on perceived control for Easterners, this study proposes that Koreans who feel lower perceived control will show more positive responses than do those who feel higher perceived control in a retail environment. In this study, along with the previous research, we define control as "an individual`s beliefs, at a given point in time, in his or her ability to effect a change, in a desired direction, on the environment" (Greenberger et al. 1989, p. 31). This study attempts to apply the concept to a retail environment by using Averill(1973)`s conceptualization of control that is able to be operationalized in three different dimensions: behavioral control, cognitive control, and decisional control. Then, this study conceptualizes high and low control in a retail setting. Based on the previous research on primary and secondary control, the study explains the high control as the situation in which an individual perceives that he or she acts as an agent explicitly to produce desired outcomes in a retail setting. This concept is similar to that of primary direct personal control. In this condition, an individual attempts to change the world so that it fits the self`s needs. Instead, the low control refers to an individual`s perceived belief that he or she does not act as an agent explicitly to produce desired outcomes in a retail setting. This concept is consistent with those of secondary, indirect, collective control. In this condition, an individual attempts to align oneself with existing realities leaving them changed but exerting control over their personal psychological impact. In the other cases, he or she tries to let other(s) to produce desired outcomes or to control the environment as a member of a group or collective, which serve as an agent of control. The previous research on this issue has evidenced that Westerners who put an emphasis on autonomy prefer high control over low control. Instead, Easterners prefer low control to high control because they value maintenance of harmony with others more than autonomy. Based on this previous research`s results, we propose several hypotheses that Koreans who feel lower perceived control will show more positive responses than do those who feel higher perceived control. Then, this study tested the hypotheses using two different experiments. The first experiment employed two purchase scenarios in a MP3 retail store and manipulated the level of perceived cognitive control by using the two different types of a salesperson`s interactions with a customer in the store. The second experiment, for manipulating the perceived decision-making control level, used two chinese restaurant scenarios that contain two different types of assortments which are item-by-item and set menus. For both of the experiments, we employed Korean college students as research subjects. For experiment 1, the ANOVA results indicated that the research subjects showed the higher level of emotional response, re-patronage intention, positive word-of-mouth intention, and confidence in the high control condition than in the low control condition. The results are consistent with our expectations before the experiment. In addition, the results are the exactly opposite direction of those of Sode

허미란,이상원 한국실과교육연구학회 2013 實科敎育硏究 Vol.19 No.4

본 연구는 바람직한 환경행동과 밀접한 관계가 있을 것으로 예상되는 요인으로 자아존중감과 통제소재를 제시한 선행연구 고찰을 바탕으로, 초등학교 5, 6학년을 학생들의 자아존중감과 통제소재를 측정, 분석하여 두 요인과 환경행동과의 관계를 규명함으로써 환경행동을 강화하는데 있어 통제소재와 자아존중감의 중요성을 재조명하고, 환경행동 증진을 위한 참고자료를 제공하는데 목적이 있다. 본 연구의 검사도구는 선행연구를 기초로 수정, 보완된 자아존중감, 통제소재, 환경행동에 관한 자기보고식 설문지이며, 측정된 결과를 분석하기 위해서 i-STATistics 통계 프로그램을 사용하였다. 초등학교 5, 6학년 학생들을 대상으로 측정된 자아존중감 및 통제소재와 환경행동의 상관관계를 분석한 연구 결과는 다음과 같다. 첫째, 초등학교 5, 6학년 학생들의 자아존중감과 통제소재에 있어 성별, 학년별로 유의한 차이는 없었다. 그러나 환경행동의 모든 하위 영역에서 여학생의 환경행동이 남학생보다 높게 나타났으며, 특히 육체적 행동 영역에서 통계적으로 유의한 차이를 나타냈다. 둘째, 통제소재 상집단과 하집단의 자아존중감 차이를 검증한 결과, 통계적으로 유의한 차이가 있었다. 따라서 통제소재가 높은 학생의 자아존중감이 통제소재가 낮은 학생의 자아존중감보다 긍정적으로 형성되어 있음을 알 수 있었다. 셋째, 자아존중감과 환경행동 및 통제소재와 환경행동의 상관관계를 분석한 결과, 각각의 요인과 환경행동의 상관관계 및 각 요인의 하위 영역과 환경행동의 상관관계에서 모두 통계적으로 유의한 상관성을 보였다. 이와 같은 결과를 토대로, 초등학교 5, 6학년 학생들의 자아존중감, 통제소재가 환경행동과 유의한 상관을 가지고 있다는 결론을 얻을 수 있었다. 따라서 환경교육의 궁극적인 목표인 환경행동을 증진시키기 위해서 자아존중감과 통제소재를 강화시킬 수 있는 프로그램의 개발이 요구되며, 후속연구로서 환경행동을 강화를 위한 초등학생용 자아존중감 및 통제소재 개발을 위한 연구도 필요할 것으로 보인다. The purpose of this study was to investigate the level and correlation of self-esteem, locus of control and environmental behavior of elementary school students. The objects of this study were 300 elementary school students selected from four elementary schools located in Seoul. The used questionnaire for students were made on the basis of pre-studies and the collected data was statistically processed and analyzed by mean frequency, standard deviation and t-test and correlation. i-STATistics was used in order to analyze the data. The finding of this study were as follows. First, there were no significant differences of self-esteem and locus of control between 5th and 6th graders in terms of the gender and grade. However, the girls were higher than the boys in subscale of environmental behavior and its all subcategories. In particular, there were statistically meaningful differences in the physical activity area. Second, after the investigation of the locus of control, it was found that there were statistically significant differences between the higher and the lower group. Therefore, the students with high locus of control have more positive self-esteem than the students with low locus of control. Third, on the investigation of correlation between self-esteem and environmental behavior, between locus of control and environmental behavior, it is found that there was statistically significant correlation not only between each factor and environmental behavior but also between each factor's subcategories and environmental behavior. Based on the findings of this study, it is necessary to develop the self-esteem and the internal-locus of control in order to improve environmental behavior.

화학물질관리법 내 화학사고 정책의 개선방안 및 산업계 지원방안 연구(Ⅱ)

서양원 ( Yang-won Suh ),박정규 ( Jeonggue Park ),간순영,조상기,한선영 한국환경정책평가연구원 2017 기본연구보고서 Vol.2017 No.-

본 연구는 「화학물질관리법」 내 화학사고 정책의 개선방안을 도출하고, 동 정책의 시행으로 어려움을 겪는 산업계에 대한 지원방안을 마련하는 데 목적이 있다. 2차년도 연구에서는 1차년도에 제시한 화학사고의 사전 환경피해평가 방법론을 중심으로 추가 분석 및 시범적용을 실시하여, 국내 도입 및 적용 가능성을 검토하고 향후 추진방향을 제안하였다. 또한 「화학물질관리법」 내 화학사고 정책이행에 대한 중소규모 사업장 및 관련 작성 전문기관의 애로사항을 조사하여, 「화학물질관리법」에 대한 개선 및 지원방안을 추가로 제시하였다. 우선 화학사고 발생을 사전에 예방하고 이에 대비하기 위해, 사전에 피해를 평가하는 방법론을 분석하였다. 현재 장외영향평가에서는 인체에 대한 위험도는 평가하나, 환경에 대한 정량적 평가요인은 반영되어 있지 않은 상황이다. 따라서 환경피해에 대한 방법론 검토 및 적용방안 마련이 필요하다. 인체 위험도 측면에서는 향후 관련 연구에 참고할 수 있도록 간략히 국외 방법론을 살펴보았으며, 환경피해 중심으로 화학사고의 사전 피해평가방법론을 분석하고 시범적용을 위한 관련 내용을 정리하였다. 이와 함께 국외 화학사고 사전환경피해평가의 활용 방안과 국내 적용 시 참고사항을 검토하였다. 국내 적용성 검토 및 보완사항 도출을 위해 일부 국내 사업장을 대상으로 사전 환경피해평가 방법론을 시범적용한 결과, 최악의 경우를 가정하면 모든 방법론에서 높은 등급(화학사고 발생 시 심각한 영향을 줄 것)의 피해가 있는 것으로 평가되었다. 다만, 현재로서는 이와 같은 국외의 사전 환경피해평가 방법론을 국내에 바로 적용하기에는 분명한 한계점이 존재하며, 적용을 위해서는 추가로 검토 및 보완이 필요한 것으로 나타났다. 또한 국외에서 개발·적용 중인 사전 환경피해평가는 특성에 따라 서로 다른 활용성을 갖지만 화학사고로 인한 환경피해를 사전에 스크리닝하는 것이 공통적인 목적으로 파악되었다. 정책 이행 지원 측면에서는 중소기업의 애로사항을 파악하기 위해 중소규모 사업장을 대상으로 의견수렴을 실시하였으며, 추가적인 현황 파악을 위하여 장외영향평가서 작성 전문기관의 의견도 수렴하였다. 수렴한 의견은 1차년도 연구에서부터 지속적으로 제기되는 애로사항과 이번 조사에서 새로 제시된 애로사항으로 구분하여 정리하고 이에 대한 시사점을 도출하였다. 이와 같은 화학사고 사전 환경피해평가의 시범적용과 활용성, 「화학물질관리법」 이행에 대한 애로사항 검토를 토대로 장외영향평가 제도 등 화학사고 예방제도의 보완을 위한 기술적·정책적 개선방안을 제시하였다. 첫째, 기술적 개선방안으로 장외영향평가 제도에서 보완이 가능한 ‘화학사고 사전 환경피해평가 방법론’을 제안하였다. 시범적용 결과를 토대로 실제 활용사례가 존재하고, 상대적으로 관련 자료 확보가 쉬우며, 다양한 환경 매체로의 확장성이 높은 체코 환경피해평가 방법론을 중심으로 국내에서 우선 적용할 수 있는 방법론을 도출하였다. 또한 이와 같은 방법론을 실제 장외영향평가의 보완방안으로 적용할 때 검토가 필요한 세부 기법 및 등급 기준 등의 항목들을 고려하여 국내 화학사고 사전 환경피해평가 적용을 위한 향후 과제를 함께 제시하였다. 둘째, 정책적 개선방안으로 2차년도에 새롭게 제기된 애로사항의 해결을 위하여 KORA 프로그램 보완사항 개선을 위한 헬프데스크운영, 장외영향평가서 및 위해관리계획서 관련 교육 확대, 위해관리계획서 주민고지 개선, 장외영향평가서 및 위해관리계획서 통합운영방안, 작성 전문기관 인력기준 개선 등을 제안하였다. 1차년도에 이어 지속적으로 제기된 애로사항의 해결 방안으로는 장외영향평가 작성대상의 정확한 파악 및 대상 업체 인식 제고를 위한 전수조사 시행을 제시하였고, 이를 위해 경제총조사에 화학물질 취급 사업장에 대한 항목을 추가하는 것을 제안하였다. 향후 「화관법」을 토대로 한 화학사고 예방제도가 원활히 이행되기 위해서는 직간접적으로 제도의 영향을 받는 산업계 및 지역 주민 등 광범위한 이해관계자들의 의견을 주기적으로 수렴하고, 이를 통하여 도출된 기술적·정책적 문제점을 지속적으로 보완해 나가야 할 것이다. The purpose of this study is to find ways to improve the chemical accident policy in the Chemicals Control Act and to provide support to industries that have difficulties in implementing the policy. Further analysis and pilot application of the pre-environmental assessment methodologies for chemical accident in the first year of the study is conducted to review the applicability of the methodologies and propose their future direction. In addition, the study investigates the difficulties of SMEs and related writing agencies implementing the chemical accident policy in the Chemicals Control Act, and proposes improvements and support measures for the Chemicals Control Act. First, the study analyzes the method of evaluating the damage in advance for prevention and preparation before the chemical accident. Currently, off-site consequence analysis evaluates the risk to humans, but it does not reflect the quantitative evaluation factors of the environment. Therefore, it is necessary to review the methodology for pre-environmental assessment and to formulate an application method. In terms of the human risk, the study has briefly discussed the methodology of foreign countries for future reference. The study focuses on analyzing the pre-environmental assessment methodologies for chemical accident and sorting out related contents for pilot application. The study has examined how pre-environmental assessment of the chemical accident is used in foreign countries, and reviewed what can be referenced in this study. Based on this, the study pilots the pre-environmental assessment methodologies for chemical accident under the domestic condition. As a result of the pilot study, it is shown that there is no methodology directly applicable to the domestic places of business, and additional review and supplementation work is required for the application. On the other hand, in order to grasp the difficulties in SMEs, opinions of institutions specialized in preparing the off-site consequence analysis are also identified. The difficulties that have been continuously raised from the first year's survey and the new difficulties presented in this survey are summarized and implications are drawn. Based on the pilot application of the methodologies for pre-environmental assessment of chemical accident and the difficulties in implementing the Chemicals Control Act, the study proposes a technological improvement plan and a policy improvement plan for the chemical accident prevention system to complement the off-site consequence analysis system. First, as a technical improvement method of chemical accident prevention system, the study proposes a pre-environmental assessment methodology for chemical accident that can technically complement the off-site consequence analysis system. Based on the results of the pilot application, there are some cases that have practical use cases and relatively easy to acquire related data. The Czech methodology with high scalability to various media was selected as the pre-environmental assessment of chemical accident. However, as a complementary measure for the off-site consequence analysis, it is necessary to carefully examine and apply the methodology in practical application considering the technical aspects and the availability of data at present. Therefore, future work for the domestic application of pre-environmental assessment of chemical accident is suggested. Second, based on the analysis of the results of the opinions of the workplace and the implementation status, the policy improvements for resolving the new difficulties and the current status of the difficulties raised in the first year and additional proposals for the lack of solutions were drawn. As a policy improvement plan for the chemical accident prevention system, KORA program support items, off-site consequence analysis, risk management plan system, improvement of related education support and improvement of awareness are proposed.

제어방법에 따른 실내온열환경 및 에너지 성능 분석

김수연(Su Yeon Kim),송두삼(Doo Sam Song) 대한설비공학회 2017 대한설비공학회 학술발표대회논문집 Vol.2017 No.6

Indoor thermal comfort is influenced by environment factors(temperature, humidity, air velocity, radiant temperature, etc) and personal factors(genders, age, clothing, metabolic rate). Set-point temperature control which is widely applied in indoor thermal environmental control uses dry-bulb temperature as a control variable because of its simple and convenience. But this simple method which is not consider other environment factors like humidity, radiant temperature and air velocity can arouse thermal discomfort and energy over-usage. Many researchers proposed the thermal comfort index such as PMV, ET*, SET*, Adaptive model, ASHRAE Comfort Chart and so on. However, these indices are rarely used as a control logic of indoor thermal environment. In this paper, the thermal environment and energy performance of the control logic in school building will be analyzed by simulation method. The results showed that the energy saving effect of Operative temperature control mode is the most effective, while Wet-bulb temperature mode is the best control method in terms of thermal comfort among the analyzed control logic in school buildings.
