The Sixteenth Meeting of the Conferences of Parties of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which was held in March 2013 in Bangkok, Thailand, listed five shark species and one genus, and uplisted one sawfish species. All new species listings will be come into force of the eighteen months delay, on the fourteenth of September, 2014. The purpose of the delay is to support the preparation of the domestic measures on shark trade by the parties, as there has been no previous experience in trading the commercially exploited aquatic species in the CITES. The CITES Secretary-General has visited several potential shark trade countries to encourage and facilitate the implementation of the new CITES listings. The newly listed sharks have been caught as a target or non-target species by Korean distant water fisheries and introduced into Korea. So the establishment or change of the domestic laws, regulations, and measures for the implementation of the new CITES species must be prepared before the effective entry date. This paper is prepared to assess the effects of the trade of the CITES listed shark species, and to suggest effective government service measures for the management of Korean distant water fisheries. The Ministry of Environment (MOE) is the general Management Authority of the CITES, and the Ministry of Food and Drug Safety (MFDS) is in charge of the medical trade of CITES listed species in Korea. By law, all imported medicines and medical materials must be inspected by the MFDS during the customs examination; this kind of authority sharing is reasonable and effective way of providing government service. Similarly, the designation of new CITES Management Authority for the trade of commercially exploited aquatic CITES species is critical and the Ministry of Oceans and Fisheries (MOF), which is now in charge of the trade of fisheries products, is the most appropriate governing body for this purpose in Korea. The revision of the National Plan of Action for Conservation and Management of Sharks, initially submitted to the Food and Agriculture Organization (FAO) of the United Nations in 2011 as a practical guideline for shark conservation in all Korean fisheries, could be a effective measure to achieve unification of conservation of endangered species and sustainable use of fisheries stocks. The proper CITES measures for the trade of listed species, such as the establishment of the documenting system for Non-detriment Findings, domestic measures suitable for the "Introduction from the Sea" clause, species specific Harmonized System Codes for the customs service, and an effective shark catch data reporting system should be in place prior to the fourteenth of September 2014.

가상수(假想水, Virtual Water)란 일정량의 농산물, 축산물, 공산품과 같은 생산품 혹은 서비스 제공에 필요한 물의양을 뜻하는 것으로 1990년대 초반 Tony Allan 교수가 처음 제시하였다. 본 연구는 Chapagain and Hoekstra (2004)이 제시한 농축산물 및 공산품의 단위 가상수량 산정방법을 분석 및 적용하여 1998년부터 2007년까지 우리나라의 가상수 수출입량을 산정하였다. 또한 가상수 수출입을 국가간 정량화하는 방법론으로 물발자국(Water Footprint) 이론을 이용하였다. 그리고 2006년 우리나라 농작물 생산량에 단위 가상수량을 적용하여 수자원장기종합계획(건설교통부, 2006)의 농업용수 수요량과 비교함으로써 단위 가상수 사용의 적절성을 검토하였다. 연구결과 현재 우리나라는 연평균 320억 $m^3$의 가상수를 농축산물 및 공산품의 무역을 통하여 순수입하고 있으며 그 양은 지속적으로 증가추세를 보이고 있다. 생산되는 농작물의 가상수량과 농업용수 수요량의 차이는 약 6억 $m^3$으로서 전체 수요량이 약 160억 $m^3$인 점을 감안한다면 상대적으로 근소한 차이로서 본 연구에서 적용한 단위 가상수량 산정방법이 타당함을 입증하였다.

Information and communication technology (ICT) is one of the primary zones that stimulates economic development in today's globalized world. It promotes technological developments in worldwide communication and manufacturing systems, as well as economic growth and development. Many economic activities, such as international trade and foreign direct investment, rely heavily on contemporary information and communications technologies (FDI). The goal of this study is to look at the dynamic relationship between FDI, ICT, trade openness, and economic growth in the context of BRICS countries from 2000 to 2018, with Gross Domestic Product as the dependent variable and Telephone subscriptions, Mobile subscriptions, Broadband subscriptions, Internet subscribers, Secure internet servers, Trade, and Foreign direct investment as the independent variables.Two variables are used as proxies to manage the macroeconomic environment, while five variables are used as proxies for ICT infrastructures. The outcomes of this study are analyzed using Generalized Methods of Movements (GMM). According to this study, ICT has a positive impact on the economic growth of a few countries. Trade openness and foreign direct investment, on the other hand, have a negative impact on economic growth. As growing countries, the BRICS must participate in economic reform and liberalization measures. This report suggests policy proposals for improving ICT standards, focusing especially on economic growth, trade openness, and increasing foreign investment in the BRICS countries.

해상운송은 개별 국가만이 아니라 세계 경제에 높은 영향력을 미치며, 글로벌가치사슬(GVSc)을 통한 분업 실현에 이바지 하고 있으며 이러한 국제분업 활동은 일상화되어 있다. 해상운송업 사이에도 국제분업을 통한 글로벌 가치사슬(GVSs)이 존재하며 국가 간 해상운송업 사이 혹은 관련 산업 사이에도 거래관계가 발생해 상호 연관구조가 긴밀한 국가들이 있다. 이에 본 연구에서는 아시아개발은행(ADB)에서 1년 단위로 발표하는 국제산업연관표(WIOT)을 이용하여 63개 국가 중에서 세계 30대 선박 보유국 안에 포함되면서 수상운송업의 총 산출액이 높은 14개 국가를 대상으로 수상운송업 간의 상호 연관구조를 분석하였다. 분석을 통해서 우리나라 수상운송업과 높은 연관구조를 가진 국가와 우리나라 수상운송업의 특징을 확인하였다. 분석 결과 우리나라는 투입구조에서 국산 중간재비중이 약 70%로 유럽의 주요 해운 국가 대비 국내산 이용 비율이 높았다. 하지만 2000년 이후로 꾸준히 국외 중간투입이 증가하면서 국외 산업과 연관구조가 높아졌으며, 발생하는 부가가치는 하락하였다. 줄어드는 부가가치에 비해 국내 산업으로 생산유발계수는 크게 변화가 없어 같은 금액 투자에도 국내에 미치는 경제적 영향은 줄어든 것으로 평가되어 해운산업의 부가가치를 높이기 위한 정책적인 방안이 필요한 것으로 생각된다. 우리나라 수상운송업과 높은 연관구조를 가진 국가는 투입구조 상에서는 미국(USA), 배분구조에서는 싱가포르(SIN), 일본(JPN) 순으로 해당 국가의 생산활동에 높은 영향을 받는 것을 확인하였다. 생산유발계수를 통한 연관구조를 보면 우리나라 수상운송업과 높은 연관구조를 가진 국가의 수상운송업은 싱가포르(SIN)이다. 싱가포르(SIN)는 유럽 항로의 중간지역으로 우리나라 수상운송업과 상호 간에 높은 생산유발효과를 주고받는 것을 확인할 수 있었다.

Purpose: This preliminary study investigated a potential of the water wall systems that provide heat storage and natural lighting control simultaneously. Method: In order for transparency of the water wall to be controlled, the study first proposed two measures: to adjust transparency of the water wall; to control transparency of water wall surface. The performance of two measures then was verified and compared by experiments. In addition, a trade-off between heat collect and heat storage resulting from using additive for adjusting transparency was investigated. Result: The experiment showed that the two measures are similar in performance. The investigation of trade-off relation showed the additive should have the same heat storage as the water to prevent decrease in thermal performance of the water wall. As an economical measure to control transparency of the water wall, this study suggested a measure of secondary heat transfer systems using shading device that first absorbs solar radiation and then transfers heat to the water wall. The experiment show that performance of the proposed measure is similar to controlling transparency of water wall surface. In conclusion, it is expected that the performance of the water wall can be economically maximized by using the proposed mean in terms of heating, cooling and lighting energy saving.

This study aims to reveal the influence of price increase in gasoline on household expenditure trade-off. The subjects were 651 households, acquired the first quarter of 1996 and 1997. This study shows the change of the auto fuel budget share in the same household and they were analyzed with the paired t-test, independent t-test. The results are as follows; 1) the price increase of auto gasoline resulted in the increase of its budget share, regardless of a household's true increase or decrease of income. 2) according to price increase in gasoline, the auto fuel budget share has been changed, therefore I divided these changes into three group on the base of it's degree of change. 3) In the group that had a decrease in auto fuel budget share compared to the degree of change, there was a trade-off between the increase in food and light & light water and the decrease of education and auto fuel budget share. Auto fuel in this group was used as discretionary good. 4) In the group that had a similar change in auto fuel budget share compared to the degree of change, there were no trade-off between expenditure items except auto fuel budget share and miscellaneous decrease. This group is the highest income group among the three groups. 5) In the group that had and increase of change in auto fuel budget share compared to the degree of change, there was a trade-off between the increase of eating-out and auto fuel, and the decrease of education and miscellaneous budget share. Auto fuel in this group was used as a discretionary good. 6) trade-off expenditure budget share showed a mixed effect between the influence of increase in gasoline price and influence of increase in true income.

The aim of this study is to apply the Water-Energy-Food-Land Nexus approach which can analyze the trade-offs among resources, and assess the holistic impacts of food security. First, we applied rice as a study crop and analyzed the trend of consumption of rice and the area of paddy fields. Second, the portfolios of water, energy, and land for rice production were constructed using data of footprints and productivity. Finally, the self-sufficiency ratio (SSR) of rice in target year was set as food security scenario and assessed the impacts of food security on water, energy, and land availability. In 2030, the SSR of rice decreased to 87 %, and water use for producing rice decreased from 4,728 to $3,350million\;m^3$, and the water availability index increased from 0.33 to 0.53. However, food security is essential issue and we set the 50 % and 100 % SSR of rice as high and low food security scenarios. For 100% SSR in 2030, about $3,508million\;m^3$ water was required and water availability index reached to 0.5. In other words, there is the trade-off between food security and water-energy-lands availability. Therefore, it is difficult to make a decision whether a high level of SSR is better or worse. However, this study showed the both positive and negative impacts by change of food security and it can be useful for setting the policy decision considering both food security and sustainable resource management at the same time.

The wetlands are facing environmental changes such as desiccation that occurs with the passage of time and reduced ecosystem services from wetlands in the city. In order to maintain the ecosystem services provided by wetlands in urban areas, a system thinking about the trade-off phenomenon of ecosystem services occurring as the wetlands undergo environmental changes is needed. Therefore, the purpose of this study is to develop strategies for wetland design using system thinking approach to enhance the resilience of ecosystem services degraded by the desiccation of wetlands and other disturbances. The objectives of this study include the system boundary and variables. Second, analyzing the dynamics of wetland design strategy. Third, it analyzes the trade-off phenomenon of ecosystem services in terms of the hydrology, hydric soil, and plants strategies to mitigate these effects. Fourth, wetland basic design to improve the resilience of ecosystem services. A wetland in Abuk-Mountain Neighborhood Park, Miryang-si, Gyeongsangnam-do, has been selected as a case study. Causal loop diagrams(CLDs) are used to analyze feedback in the wetland regime. In summary, hydrology, hydric soil, and plants is suggested as system boundaries to design plan. Design strategies for the wetland focused on robustness, redundancy, rapidity, and resourcefulness as a result of CLD analysis are first proposed in order to effectively maintain the wetland regime over the long term. Secondly, in a section related to hydrology, the CLD results show the trade-offs between provisioning-cultural services and regulating services. In order to control these services, a "water cycling system" has been implemented due to its strength in terms of robustness. The CLDs for hydric soil showed the trade-offs between regulating services and supporting services. An "installation of storm drainage for maintaining water levels" was selected due to the strength offered in terms of redundancy and rapidity. The CLDs for plants showed the trade-offs between provisioning - cultural services and regulating services. In order to control the strategic points, the "planting of indigenous vegetation" was suggested given the strength in terms of redundancy. In this study, a wetland design method is proposed that can improve the resilience of wetland ecosystem services by analyzing the dynamics overtime. The results of this research can theoretically be applied to help restore ecosystem services in wetlands using ecological landscape design. In addition, this study will contribute to reducing maintenance costs by improving wetland resilience.

Over the past several years, sea trade have increased traffic by ships which highlighted a problem of unwanted species invading the surrounding seas through ship's ballast water discharge. Maritime trade volume has continuously increased worldwide and the problem still exists. The respective countries are spending billions of dollars in an effort to clean up the contamination and prevent pollution. As part of an effort to solve marine environmental problem, BWM(Ballast Water Management) convention was adopted at a diplomatic conference on Feb. 13 2004. In order to comply harmoniously this convention by each country. This convention will be effective after 12 months from the date which 30 countries ratified accounting for more than 35% of the world merchant shipping volume. On Sep. 8 2016, Finland ratified this convention and effective condition was satisfied as 52 states and world merchant vessel fleet 35.1441%. Thus, after Sep. 8 2017, all existing vessels shall be equipped with BWTS(Ballast Water Treatment System) in accordance with D-2 Regulation, which physically handles ballast water from ballast water exchange system(D-1 Regulation). In this study, we analyzed in detail the optimal design method using the Risk Analysis and Evaluation technique which is mainly used in the manufacturing factory or the risky work site comparing with the traditional design concept method applying various criteria. The Risk Assessment Method is a series of processes for finding the Risk Factors in the design process, analyzing a probility of the accident and size of the accident and then quantifying the Risk Incidence and finally taking measures. In this study, this method was carried out for Electrolysis treatment type on DWT 180K Bulk Carrier using "HAZOP Study" method among various methods. In the Electrolysis type, 63 hazardous elements were identified.
