  • 최근 기후변화에 따라 식품안전에 대한 위험성도 증가되고 있다. 따라서 식품안전과 기후가 어떤 관련성을 가지고 있는지 살펴보기 위하여, 1999년부터 2009년까지 수집된 식품안전 사건사고 보도자료와 60개 지점 평균한 월별 기후자료(평균기온, 최고기온, 최저기온, 강수량, 상대습도)를 사용하여 식품안전과 기후요소와의 관련성을 분석하였다. 11년간 국내 각종 언론매체로부터 조사한 729건의 식품안전사건사고 자료를 추출한 후 식품안전 사건사고 자료를 위해요인에 따라 화학적, 생물학적, 물리적 위해요인의 3가지로 구분하여, 월별 자료를 평균한 연도별 자료(Annual data)에 대하여 각각 기후요소와 식품안전 사건 사고 자료에 대한 피어슨곱적률 상관계수(Pearson product-moment correlation coefficient)를 산출하였다. 분석 결과, 식품안전 사건사고와 강수량은 음의 상관 관계(-0.48)를 보였고, 최저기온과는 양의 상관 관계(0.45)를 보였다. 강수량은 생물학적 위해인자와 물리적 위해인자에 대해 가장 높은 상관 관계를 보였으며, 기온은 화학적 위해인자와 가장 높은 상관 관계를 보였다. 특이할 점은 식품안전 사건사고 자료에는 식품을 제조, 가공하고, 소비를 결정하는 인간 행동과 관련된 인문적인 요소가 포함되어 있으므로, 가시적인 위험이 나타나는 경우, 위해를 방지하는 선택을 통해 식품안전 사건사고가 감소할 개연성이 있다는 것이다. 따라서 가시적인 현상인 강수량과는 부적인 상관 관계를 보였고, 기온의 경우에도 극단적인 경우에는 소비자의 행동요소가 포함되므로 최고기온보다는 평균기온과 최저기온에서 더 높은 관련성을 나타냈다. 즉, 식품안전 사건사고 자료는 직접적인 병원체에 대한 연구와 달리 인간의 행동과 관련된 요소가 포함되어 있는 것으로 분석되었다. 이 연구가 향후 기후변화에 따른 식품안전 영향 평가에 있어서 기본 정보를 제공할 수 있기를 기대한다.

  • The cement industry is one of the rapidly growing industry in Ethiopia. The average per capita cement consumption of the country has increased from 39kg to 62kg. However, this is still way below than the global average per capita consumption of 500kg. The Ethiopian government is planning to expand its cement industry by upgrading the current cement plants and also opening of new cement plants in order to meet the future demand of the country. Currently, the number of cement plants in Ethiopia has reached to 20. By the year 2025, per capita cement consumption is expected to increase to 179kg. Recently, Ethiopia has become one of Africa's largest market for the cement industry. In addition, Ethiopia has become the major exporter of cement in the Sub-Saharan African region. The Ethiopian cement industry is highly dependent on the use of imported energy sources for its production. This situation has a significant amount of impact on the high production costs of the industry. This paper will try to review the history, production, available resources, the technologies and energy use of the Ethiopian cement industry.

  • The need fur higher grid resolution in climate models is often discussed (e.g. McAvaney et al.,2001) because a number of important oceanic processes are not resolved by the current generation of coupled models, e.g., boundary currents, mesoscale eddy fluxes, sill through flows. McClean et al., (1997) and Bryan and Smith (1998) have compared simulated mesoscale variability in simulations at several eddy-resolving resolutions to TOPEX/Poseidon and similar data. (omitted)

  • Climate change causes changes in rainfall patterns, temperature and drought frequency. Climate change impact influences on water management and crop production. It is critical issue in agricultural industry. Rice is a staple cereal crop in South Korea and Korea uses a ponding system for its paddy fields which requires a significant amount of water. In addition, water supply has inter-relationship with crop production which indicates water productivity. Therefore, it is important to assess overall impacts of climate change on water resource and crop production. A water footprint concept is an indicator which shows relationship between water use and crop yield. In addition, it generally composed of three components depending on water resources: green, blue, grey water. This study analyzed the change trend of water footprint of paddy rice under the climate change. The downscaled climate data from HadGEM3-RA based on RCP 8.5 scenario was applied as future periods (2020s, 2050s, 2080s), and historical climate data was set to base line (1990s). Depending on agro-climatic zones, Suwon and Jeonju were selected for study area. A yield of paddy rice was simulated by using FAO-AquaCrop 5.0, which is a water-driven crop model. Model was calibrated by adjusting parameters and was validated by Mann-Whitney U test statistically. The means of water footprint were projected increase by 55 % (2020s), 51 % (2050s) and 48 % (2080s), respectively, from the baseline value of $767m^2/ton$ in Suwon. In case of Jeonju, total water footprint was projected to increase by 46 % (2020s), 45 % (2050s), 12 % (2080s), respectively, from the baseline value of $765m^2/ton$. The results are expected to be useful for paddy water management and operation of water supply system and apply in establishing long-term policies for agricultural water resources.

  • 우리나라 정부는 국가 온실가스 감축 목표를 설정하고, 부문별, 업종별 온실가스 감축 대책을 추진하고 있으며, 이에 맞추어 경기도 등 광역시 도와 기초지자체들도 지역 특성에 적합한 기후변화대응 대책을 수립 추진하고 있다. 하지만 지자체의 경우 저감목표 수립을 위한 정책 단위별 온실가스 배출현황 및 장래 배출량 전망치가 명확하지 않아 많은 어려움이 있다. 올바른 기후변화 적응정책을 수립하기 위해서는 정책적 방향과 검증된 온실가스 발생량 평가가 바탕이 되어야 하고, 국가 차원의 기후변화 영향 및 취약성 평가와 함께 지역의 특성과 여건을 고려한 방법론을 개발할 필요가 있다. 이에 본 연구는 기초지자체인 경기도 시흥시를 대상으로 국립환경과학원에서 지자체에서 쉽게 BAU(Business As Usual) 배출량을 산출할 수 있도록 제작한 GEBT(Greenhouse gas Emission Business as usual Tool) 모형을 사용하여 시흥시의 온실가스 발생량을 산정하였다.

  • Nowadays meteorological information is systemized as a useful knowledge which has a significant effect on the overall industrial domains over the simple data. The distribution industry, which has the short life cycle, depends on the meteorological information at the strategic level. However, it is necessary to pay attention to the continuous investment in meteorological information because there is a hostility to paying for a service, particularly it does not provide accurate and reliable information. Therefore, the purpose of this study is to increase the usefulness of meteorological information in the distribution industry for its economic effectiveness from the core meteorological factors. We found significant meteorological factors (temperature, precipitation, disaster) that have a critical influence on the distribution industry through the hierarchical analysis process, and their importance according to the type of distribution channels, such as department store, large-scale discount store, convenience store, and home shopping. We performed the AHP analysis with 103 survey samples by middle managers from the various distribution channels. We found that precipitation is the critical meteorological factor across the distribution industry. Based on this result, we stress the difference in the level of the meteorological information in order for the effectiveness of each type of distribution channels.

  • This study focus on the analysis of the energy performance in accordance with apartment houses arrangement type by using Ecotect Analysis. Korea, energy-poor country, the rate of dependence on imports amount to 94%, have to reduce energy consumption part of building except in industry and transport which affect the economic. Apartment houses are built in various forms in order to reduce energy, are modelled in each window area ratio, shape, orientation, climate through simulation. Through this study, we can analyze energy performance by form, window area ratio, orientation, climate change and know the optimal elements by the form. In particular, although there have been studied research on the window area ratio and research related to the arrangement form, determined that the information on the regional climate characteristics and the direction of placement is less than existing research. To supplement those problem, adding to seven direction(West, S-60-W, S-30-W, South, S-30-E, S-60-E, East) and climatic element(southern region) is characteristic of this study. The form of apartment houses was modelled for apartment houses built in the 10 years since. And each modeling were analyzed by Ecotect Analysis.

  • The purpose of this study was to investigate physiological responses such as rectal temperature, skin temperature, micro climate, sweat rate and subjective sensations using cold protective clothing with five different clo value. The clo value was measured by thermal manikin in windless condition. Healthy five 20's males volunteered as subjects for wearing trial experiment. The climate chamber was controlled at $50^{\circ}C$, 65% RH. The experiment consisted of repeated exercise and recovery periods. We found that the higher clo value has, the higher mean skin temperature, micro climate and sweat rate show. They felt warm and wet with higher insulation clothing. Thermal comfort increased in the last recovery period after exercise. There was significant difference between five cold protective clothing. In correlation analysis of clo value, it showed that correlation coefficient(r) values were more than 0.8. Therefore, in terms of clothing insulation, we found that correlation between thermal manikin experiment and wearing trial experiment was high. Clothing insulation could be variable according to many factors such as body movement, covering area, clothing gap, layering and design. Considering the body movement, we thought that insulation measurement need to carry out both thermal manikin experiment and wearing trial experiment.
