최근 국제적으로 수산부문에 대한 현안문제 중의 하나는 어업에 있어 어획능력 (fishing capacity)을 감축시키고자 하는 것이다. 이는 어획능력이 크게 증강되어 어업자원에 대한 어획압력이 증가하여 자원남획을 초래하고 있을 뿐만 아니라 추가적인 비용이 소모되므로 지속 가능하고 경영안정적인 어업발전을 위해서는 과잉된 어획능력의 감축이 시급하기 때문이다. 더욱이 1999년에는 세계식량농업기구(FAO)가 '어획능력 관리를 위한 국제적 행동계획'을 채택하고, 각국으로 하여금 어업별 어획능력 측정과 과잉 어획 능력 감축을 위한 관리방안 마련을 촉구하였다. 본 연구에서는 1978년~2003년간의 어획량과 어획노력량(어선척수, 톤수, 마력수, 그리고 조업일수) 자료를 이용한 자료포락분석(DEA) 기법으로 우리나라 대형선망어업의 연도별 어획능력 변화를 측정해 보았다. 분석 결과, 2003년도의 경우 대형선망어업의 어획능력 활용도가 약 50% 수준으로 나타나 유휴 어획능력이 존재하는 것으로 평가되었다. 그리고 과잉 어획능력 감축 수준을 파악하기 위한 민감도 분석 결과 2003년도 어획량을 유지하기 위해서는 어선척수(마력수와 톤수 포함)를 50% 정도 삭감하든가 아님 조업일수를 약 63% 정도 줄여야 하는 것으로 나타났다. 또한 대형선망어업의 최대 지속적 어획량(MSY) 수준을 유지하기 위해서는 어선척수(톤수와 마력수 포함)에 대한 30% 삭감이나 조업일수의 약 60% 감소가 필요한 것으로 분석되었다.

The safe management of radioactive waste is a national task required for sustainable generation of nuclear power and for energy self-reliance in Korea. Since the initial introduction of nuclear power to Korea in 1978, rapid growth in nuclear power has been achieved. This large nuclear power generation program has produced a significant amount of radioactive waste, both low- and intermediate-level waste (LILW) and spent nuclear fuel (SNF); and the amount of waste is steadily growing. For the management of LILW, the Wolsong LILW Disposal Center, which has a final waste disposal capacity of 800,000 drums, is under construction, and is expected to be completed by June 2014. Korean policy about how to manage the SNF has not yet been decided. In 2004, the Atomic Energy Commission decided that a national policy for SNF management should be established considering both technological development and public consensus. Currently, SNF is being stored at reactor sites under the responsibility of plant operator. The at-reactor SNF storage capacity will run out starting in 2024. In this paper, the fundamental principles and steps for implementation of a Korean policy for national radioactive waste management are introduced. Korean practices and prospects regarding radioactive waste management are also summarized, with a focus on strategy for policy-making on SNF management.

This study analyzed the CEO New Year's addresses of major Korean companies, extracting key topics for employees via text mining techniques. An intended contribution of this study is to assist reporters, analysts, and researchers in gaining a better understanding of the New Year's addresses by elucidating the implicit and implicative features of messages within. To this end, this study collected and analyzed 545 New Year's addresses published between 2012 and 2021 by the top 66 Korean companies in terms of market capitalization. Research methodologies applied include text clustering, word embedding of keywords, frequency analysis, and topic modeling. Our main findings suggest that the messages in the New Year's addresses were categorized into nine topics-organizational culture, global advancement, substantial management, business reorganization, capacity building, market leadership, management innovation, sustainable management, and technology development. Next, this study further analyzed the managerial significance of each topic and discussed their characteristics from the perspectives of time, industry, and corporate groups. Companies were typically found to emphasize sound management, market leadership, and business reorganization during economic downturns while stressing capacity building and organizational culture during market transition periods. Also, companies belonging to corporate groups tended to emphasize founding philosophy and corporate culture.

최근 서울시는 TOD 기법을 활용하여 도심을 재활성화하기 위한 대규모 사업을 추진하고 있다. 그런데 TOD형 개발은 고밀개발을 전제로 하기 때문에 교통혼잡이나 환경의 질에 영향을 끼친다. 본 논문의 목적은 도로 뿐 아니라 버스, 지하철 등의 용량을 함께 고려한 통합교통서비스지표를 개발하여 TOD 개발을 촉진하는데 있다. 이를 위해 외국사례를 검토하고, 새로운 통합교통서비스 지표를 개발하고 이를 활용하여 서울시 도심에서 TOD형 고밀개발이 일어났을 때 교통부분의 기대효과를 분석하였다. 본 연구에서 개발한 통합교통서비스지표는 승용차, 택시, 버스로 구성된 도로서비스환경지표와, 지하철서비스환경 지표로 구성되며, 두 개의 지표를 통합하는 방법은 각 교통죤별 서비스환경에 각 죤별 수단분담률로 가중평균해서 계산하되, 각 수단분담률의 합은 1로 하였다. 이러한 통합교통서비스환경(ITLOS: Integrated Transportation Level Of Service)의 수치는 0에서 1사이의 값을 가지게 되며, 0에 가까울수록 개발에 필요한 교통여건이 좋은 것으로 해석된다. 본 연구에서 도심고밀개발에 따른 기대효과를 분석하기 위해 대중교통과 도로교통을 동시에 고려한 통합교통서비스지표와 도로교통서비스 수준만을 고려하는 통행속도 지표를 활용했다. 두 지표 모두 도심 고밀 개발 시 교통서비스 수준은 악화되는 것으로 나타났고 서울시 전체의 교통서비스 수준은 개선되는 것으로 분석되었다. 하지만 통합교통서비스 지표를 사용할 경우 비율적으로 도심교통상황의 악화 정도는 평균속도지표의 경우에 비해 낮게 나타났고, 반면 서울시 전체적인 개선폭은 비율적으로 상당히 높게 분석되었다.

In early 90s the worldwide awareness about the energy crisis and global warming had been increased and emission reduction (by improving energy efficiency), as well as increasing the capacity of clean and renewable energies, showed themselves as the most important steps towards the sustainable development approach. However, investigations on Iran's environmental situation show huge decline in recent decades and apparently there is no sense of urgency about these issues through the vision of Iranian politicians. In this article the idea of replacing the old gas turbines of Polkalleh natural gas compressor station - as one of the main compressor stations of Iran - with newer and more efficient gas turbines is evaluated, emphatically for reducing greenhouse gases emissions and their environmental costs and decreasing natural gas consumption as well. Clearly such idea is costly, but analyzing its economic impacts, huge declines in annual costs and greenhouse gases emissions can be seen as well. So an investment about $95 million can decrease 40% of Polkalleh compressor station annual costs, 25% of natural consumption and 30% of $CO_2$ and $NO_x$ emissions. Besides the simple payback period of this investment is about 2.5 years from the cut-expenses of annual costs.

'Health in All Policies' is a new strategy for governance for health in 21st century. The evolution of health promotion has affected the creation of the strategy through the efforts to tackle health inequalities by addressing social determinants of health. More concern about health inequalities, involving wider policy areas, and higher level of institutionalization distinguish the strategy from the old intersectoral collaboration such as intersectoral action for health and healthy public policy. Making intersectoral collaboration the mainstream of policy making is important to address integrated policy agendas such as 'Health in All Policies' and 'Sustainable Development Goals.' Political leadership and interpersonal skills are also required to strengthen the capacity of public health sector for implementing 'Health in All Policies' in local, national, and international circumstances.

A sediments are Integral called as gravel, sand, clay, mineral materials which are settling in bottom layer of reservoir, stream, and oceans from land. In practical problems relations of sediments are flood by decreed of flow capacity and down of water quality. Dredged sediments are composed with constructed material and variety of pollutant compounds. Therefore, it is very much of cost effects in nationally, if development for use of constructed material separated only constructed material within sediments. And it will be continue to the dredge operation of stream sediment for retrofit of water environment and sustainable's after the years. The following results could be obtained : In case of high concentration sediments, sample for design of CDF was shown property of flocculent settling. Assuming that average inflow rate is 1, 000㎥/hr, mean residence time( $T_{d}$), average ponding depth( $H_{pd}$ ), and design surface area for flocculent settling( $A_{df}$ ) were 5 hr, 0.6m, and 15, 750 $m^2$ respectivelyrespectivelyy
