  • The negative fishery factors from an environmental perspective are greenhouse gas emissions due to high fossil fuel use, destruction of underwater ecosystems by bottom trawls, a reduction in resources by fishing, and damage to ecosystem diversity. In particular, the greenhouse gas emissions from fisheries is an important issue based on the Cancun meeting in Mexico in 1992 and the Kyoto protocol in 2005. However, no investigations on the GHG emissions from Korean fisheries have been conducted. Therefore, a quantitative analysis of GHG emissions from the Korean fishery industry is needed as a first step to identify a method to reduce GHG emissions from fisheries. The purpose of this study was to investigate the degree of GHG emitted from fisheries. Here, we calculated the GHG emissions from four main Korean fisheries(i.e., large trawls, large purse seines, Danish seines, and bottom pair trawls) using the life cycle assessment(LCA) method. The system boundary and input parameters for each process level were defined for LCA analysis. The fuel use coefficient of each fishery was also calculated. The GHG emissions from edible seafood were calculated considering different consuming areas. The results will be helpful to understand GHG emissions from Korean fisheries.

  • 최근 환경오염과 생태학적 환경문제가 사회적 중요한 관심사로 인식되고 있다. 포장디자인에 있어서도 재활용과 재사용에 대한 요구와 함께 스티로폼이나 플라스틱을 대체하는 친환경 포장용기와 생분해성 필름 등의 포장재의 개발과 생산이 점차 증가하고 있다. 이러한 사회적 배경에서 본 연구에서는 환경친화적 포장디자인의 개발을 위한 가이드라인 설정을 목적으로 하고 있다. 연구내용은 환경친화적 디자인의 개념과 에코 포장디자인 적용범주, 국내외 에코패키지의 동향 및 포장재 현황을 살펴보고, 각종 정책과 규정 및 관련지침 등의 이론적 자료들을 근거로 일반적으로 고려되고 있는 에코패키지의 기본 방향과 체크리스트를 분석하였으며 이에 따른 가이드 라인 및 수행 절차를 고찰하였다. 에코 패키지의 기본방향은 첫째, 포장디자인의 제작, 사용, 폐기에 이르는 전과정에서 환경측면을 고려해야 하며 둘째, 비용과 품질, 시장성, 디자인 등 다중요소를 고려해야 한다. 셋째, 디자인 부서와 제품설계부서, 생산부서, 환경팀 등 조직 내의 다른 시스템과 기능적으로 협력하여야 하며 넷째, 기업의 다른 여러 가지 환경 활동을 통해 잠재적인 소비자와 시장을 확대할 수 있다는 것이다. 가이드라인의 내용은 자원 절감과 물질 사용량 절감, 재활용성 확대, 에너지 효율 향상, 유해 물질 저감과 안전성 확보, 폐기 효율성을 중심으로 하고 있다. 환경 친화적 포장디자인의 실천을 통해 환경영향성을 개선하고 비용을 감소시키며 소비자의 이미지 개선에도 기여할 것으로 기대된다.

  • The objective of the study is to develop life cycle inventory (LCI) database of dam, a major facility for irrigation water supply. The types of database developed are three out of nine dams according to the size of the wate r storage capacity: two kinds larger than 500,000 $m^3$ depending on gate for discharging (Type 1) and the other dam smaller than 500,000 $m^3$ (Type 2). According to the LCI analysis, type 1 larger than 500,000 $m^3$ storage capacity with gate has the lowest environment impact in the 6 impact categories. The impact of the type 1 accounts for 7~35 % of the type 2 for supplying irrigation water. Comparing with the environment impacts of water for other uses such as drinking and industrial water, the impacts of 1 $m^3$ irrigation water supply is 4~45 % of the one for industrial water supply and 1~16 % of the drinking water's. The three types of LCI DB on the irrigation water by dams will be useful in the application of Life Cycle Assessment in agricultural products and environmental labelling including carbon footprint since it is complied to the guidelines of LCI DB constr uction issued by Ministry of Environment and Ministry of Knowledge Economy.

  • 부대기동 및 실사격을 적용한 군사훈련이 가장 사실적이며 현실감이 있지만, 부대기동에 따른 교통체증 유발과 실사격 훈련에 대한 민원 증가로 인하여 실기동에 의한 군사훈련을 실시하기에는 많은 어려움이 있다. 그러므로 실사격 훈련의 제한 및 통제형 선형훈련으로 인하여 현장감이 저하되고 학습효과가 상대적으로 떨어지게 되는 단점을 극복하기 위하여, 미국, 영국, 독일, 프랑스 등 군사선진국들은 실전적 훈련묘사 및 정밀 훈련분석이 가능한 과학화 전투훈련장을 구축하여 군사훈련의 성과를 높이고 있다. 국내에서도 육군 과학화 전투훈련장(KCTC) 구축사업이 현재 진행중에 있다. 과학화 전투훈련은 일반적으로 마일즈 장비와 시뮬레이션을 사용하여, 지휘/통제/통신 및 기동, 전투근무 지원에 이르는 군사훈련 전과정을 모의하며, 직/곡사화기 교전, 화학 및 지뢰지대 운용, 항공지원 등 전투과정을 재현함으로써 훈련에 참여하는 지휘관과 병사로 하여금 현장감 있는 전투훈련을 유도한다. 이러한 과학화 전투훈련이 실제 훈련과 동일한 훈련효과를 창출하기 위해서는, 신뢰성 있는 교전 피해평가가 필요하다. 예를 들어, 곡사화기에 의한 살상범위, 피해정도 등이 실무부대 전투결과들과 큰 차이가 발생하면 소기의 훈련목적을 달성할 수 없다. 본 고는 과학화 전투훈련장의 전투피해평가 자료체계에 대한 객관적이고 신뢰성 있는 자료검증방법을 제시하여, 향후 과학화 전투훈련의 신뢰성 제고에 기여하고자 한다.

  • For the purpose of evaluating the eco-efficiency(EE) on surplus heat generated from industrial process, techniques of life cycle assessment are adopted in this study. Because it can be indicated both environmental impacts and economic benefits, EE is well known as a useful tool for symbiosis network on the sustainable development of new projects and businesses. To evaluate environmental impacts, the categories were divided into two areas of resource depletion and global warming potential. It can be seen that environmental impact increased a little but much higher economic benefit on the company, environmental performance and economic value were improved on the apartment by the district heating, respectively. In result, eco-industrial park(EIP) project on surplus heat should be found sustainable new business because the EE was in the area of fully positively eco-efficiency and, moreover resource depletion was taken place than the reduction of greenhouse gas.

  • The fishing industry has a negative effect on the environment due to greenhouse gas (GHG) emissions with the high use of fossil fuels, the destruction of underwater ecosystems by bottom trawls, reduction in resources by fishing, and altered ecosystem diversity. GHG emissions from fisheries were discussed at the Canc$\acute{u}$n meeting in Mexico in 1992 and are part of the Kyoto protocol in 2005. However, few studies have investigated the GHG emissions from Korean fisheries. To find a way to reduce GHG emissions from fisheries, quantitative analysis of GHG emissions from the Korean fishery industry is needed. Therefore, this study investigated the GHG emissions from the Korean Danish seine fishery using the life cycle assessment (LCA) method. The system boundary and input parameters for each process level are defined for the LCA analysis. The fuel-use coefficient of the fishery is also calculated. The GHG emissions from the representative fish caught by the Danish seine fishery are considered and the GHG emissions for the edible weight of fishes are calculated, considering consumption in different areas and different slaughtering processes. The results will help to understand the GHG emissions from Korean fisheries.

  • Rockmass properties have great influence on blasting performance so that it cannot be overemphasized to analyze rockmass properties and to perform blast design based on them. Up to the present, however blast design is performed either considering only uniaxial compressive strength of intact rock or using RMR classification as a blast ability classification scheme. In this paper Ashby's approach is adopted to evaluate blast index. In addition. rockmass classification for the blast design based on joint survey results and pattern design procedure are added to Ashby's original approach. With this extended approach, blastability can be classified considering joint properties and objectiveness of evaluated blast index can be confirmed. This approach is anticipated to enhance the tunnel blast design by considering joint properties and classifying the rockmass for blast design.

  • The purpose of this research is to evaluate patient's satisfaction and clinician' knowledge level about pain, nausea, vomiting, and temperature management of patients after operation by develop an web-based evidence-based practice guideline about pain, nausea, vomiting, and temperature control after operation in order to apply the guideline operation patients. The collected data was analyzed through real number, average, standard deviation, t-test and repeated ANOVA by using SPSS/WIN 17.0 program. The study subjects showed a significant difference in the level of knowledge about pain, nausea/vomiting, and temperature control after operation and patient's satisfaction, before and after applying the web-based evidence-based practice guideline.

  • This study tries to present a new perspective for the coding and coding education. Therefore, this study analyzes coding game as performative writing. First, coding as writing process has the mechanism of serial expansion and circulation by utilizing basic code blocks. And coding as writing process produces a meaning as unit operation that generate an emergent game play. Second, coding as performative writing displays the speaking and writing at the same time and is embodied in game play. Also, absence of failure and correction makes possible users to explore the problem area and to strengthen the problem-solving ability.
