폐플라스틱으로 인한 지구환경 오염 문제의 해결책으로 분해성 플라스틱 개발이 유력한 대안으로 제시돼, 지난 1980년대 중반 이후 이러한 분해성 플라스틱 개발이 활발히 진행되어 왔다. 그 결과 현재 많은 제품이 개발되어 이용되고 있지만, 그러나 아직까지 분해성 플라스틱에 대한 정의가 명확하지 않고 평가방법도 정립되어 있지 않은 실정이다. 그밖에 경제성이라든가 물성, 분해속도 등 여러 조건을 충족시켜 범용화 할 수 있는 분해성 플라스틱을 보기까지는 앞으로도

As a reinforcement material for RC members, the modified epoxy mortar has been reported one of the superior materials since the material can improve the load capacity and the seismic performance of the RC members. However, there were few experimental studies and analytical research for improving seismic performance with the material. This study is to propose an effective reinforcement plan for RC Ordinary Moment Resisting Frame (OMRF) with the evaluation of seismic performance and economic analysis. For the objective, first, the load-deflection curve of a simple beam specimen was compared with the analytical results. Second, a 5-story RC OMRF structure was designed only for gravity load and the alternatives for seismic reinforcement were suggested. Third, pushover analysis was executed for evaluation of design coefficients and seismic performance of the structures. Finally, an effective reinforcement plan was suggested based on the results of quantity take-off and economic analysis. The findings of this study can be utilized as the basic data when the modified epoxy mortar is applied to practice for improving the seismic performance of RC members.

This study estimated and analyzed the incremental profits to compare the imported buff-tailed bumblebees, Bombus terrestris, and their pollination alternatives. A result of the analysis showed that the incremental profit, which is defined as the sales revenue minus the common production cost, was higher when using pollinator insects than when using the artificial pollination and that the incremental costs were lower when using domestic bumblebees or artificial pollination than when using imported bumblebees or honeybees. The incremental profits of each alternative were 46,801 million won for imported bumblebees, 47,170 million won for domestic bumblebees, 46,975 million won for honeybees, and 29,839 million won for artificial pollination. The incremental profit means the accounting profit that can be realized from each alternative. However, not all of the accounting profits can be attributed to pollen-mediated alternatives since they include potential costs such as imputed rent or normal profits. Considering the opportunity costs, which are the potential costs, it appears that the alternative of using imported bumblebees can lead to an economic loss. It means that fruit and vegetable farmers can expect additional economic profits if they choose other alternatives instead of using imported bumblebees.

This study aims to assess an effectiveness of the revitalization policy of traditional market which has been put in force since the late 1990's through a case study of Gyeongbuk province in Korea. According to a qualitative assessment of the improvement project of market facilities and the modernization project of marketing technique, each project has little effect. This seems to be caused by the existing revitalization policy without full considerations of reinforcing the spatial competitiveness of traditional markets. This study suggests an alternative of the revitalization policy of traditional markets concentrating on the spatial competitiveness of them.

This paper includes consideration for construction of Sejong City and seeking its alternative. Korean government has gone ahead with the relocation of 35 ministries of central government from Seoul metropolitan area to Sejong city for balanced regional development. But many specialists are worried about the spatial division of government function because such a spatial division would bring down the functional efficiency of central government. This paper proposes to make Sejong city the administrative capital city instead of the relocation of some ministries to Sejong city, and discusses the necessity and appropriateness to develop Sejong city as an administrative capital city.

Recently, the frequency of extreme rainfall event has increased due to climate change and impermeable area also has increased due to rapid urbanization. Therefore, we ought to prepare countermeasures for flood reduction to reduce the damage. To consider climate change, the frequency based rainfall was calculated according to the aimed period(reference : 1971~2010, Target period I : 2011~2040, Target period II : 2041~2070, Target period III : 2071~2100) and the flood discharge was also calculated by climate change using HEC-HMS model. Also, the flood elevation was calculated by each alternative through HEC-RAS model, setting 5 sizes of drainage pumps and reservoirs respectively. The flood map was constructed using topographical data and flood elevation, and the economic analysis was conducted for reduction of flood damage using Multi dimension - Flood Damage Analysis, MD-FDA. As a result of the analysis on the flood control effect, a head of drainage pump was reduced by 0.06m up to 0.44m while it was reduced by 0.01m up to 1.86m in the case of a detention pond. The flooded area shrunk by up to 32.64% from 0.3% and inundation depth also dropped. As a result of a comparison of the Benefit/Cost index estimated by the economic analysis, detention pond E in period I and pump D in period II and III were deemed appropriate as an alternative for climate change. The results are expected to be used as good practices when implementing the flood control works considering climate change.

Since the mid-to-late 1990s, there have obviously been many changes in the North Korean economy. Since the change has been more pronounced since Kim Jong Un took power in 2012, the purpose of the paper is to track the trend of economic policy by timing. In this paper, I use LDA Topic Modeling, a text-mining analyzer method, to analyze the economics journal "Economic Research," which is a representative literature in the economic field published in North Korea. An in-depth analysis of the "economic research," which has an unrivaled position as an economic journal produced in North Korea, can be said to be an essential task in tracking the reality, limitations facing the economy and alternatives that North Korean authorities are aware of. Through the "Economic Research," where various topics of debate on the North Korean economy are hidden, the North Korean leader's economic policy flow is examined and the contents of the "change" intended by the current Kim Jong-un regime are analyzed.

This study analyzes the regional industrial policies of Daegu based on previous discussions on the concepts and characteristics of regional industrial policies in Korea. Because of the institutional limitations of regional industrial policies in Korea, the industrial policies of Daegu are more government-led in planning and promoting industrial development. In addition, regional industrial policies have been established and executed not as regional policies but as part of sectional policies, and are not properly connected to other regional development policies. What is more, the step-by-step objectives of industrial policies are not defined clearly and, as a result, the means of the policies are not specific. In order to overcome these problems, there should be a paradigmatic transition in making regional industrial policies, which reflects not only economic factors but also the social and cultural factors of the region. Moreover, place-based policies should be planned and promoted that categorize areas subject to the policies through comprehended analysis of regional industrial environment and combine means by section.

The development paradigm based on modernization theory and economic growth since the WWII reached an impasse in the 1980s. As an alternative, the new perspective on development as a whole social development beyond economic growth has emerged, and culture as an important method for as well as a approach to development has been emphasized. Post-development theories destruct the European development concept and suggest alternative developments emphasizing culture restoration, endogenous growth, diversity, and neopopulist developments movement emphasize community, gender, ownership, and participation. International Organizations such as UNESCO have also examined and developed the relations between culture and development. Although different from that of the past development paradigm, acknowledging other cultures, however, this elaborated concept of culture has some limitations and need to be reconceptualized through applying the geographical concept of 'relational place.' The concept of relational place can help recognize internal diversity within culture and community and link them to a broader economic and political contexts.

무한경쟁시대를 맞이하여 세계는 고 부가가치 경제구조로 전환이 빨라지고 있는 이 시점에서, 대기업을 중심으로 한 성장프라이드 정책에 의해 진행되어온 우리 경제구조가 IMF구제 금융을 받아들임으로써 그 한계를 들어내고 이에 대한 대안으로 떠 오른 것이 벤처기업이다. 벤처기업은 정보동신, 소프트웨어, 첨단산업분야를 주요 사업 영역으로 삼고 있으면, 첨단 고 부가가치 기술을 보유하고 있기 때문에 이에 정보통신부는 정보통신분야의 벤처기업에 대한 투자자금 공급기반을 확충하기 위해 2002년까지 총 4,000억원 정도의 정보통신 벤처기업 투자펀드를 조성할 계획이다. 이처럼 벤처기업의 중요성이 부각되고 있는 이 시점에서 이에 대한 공정하고 엄격한 성과측정이 중요시되고 있다. 경제성 평가모형과 관련한 연구는 재무적인 측면과 비재무적인 측면으로 구분하여 진행되어 왔으며, 본 연구에서는 비재무적 측면의 BSC(Balanced Score Card)를 가지고 경제성을 평가하려 한다. BSC는 기존의 재무적 실과지표 뿐만 아니라 고객관점, 내부 경영프로세스관점, 학습과 성장관점의 4가지 차원에서 통합적인 성과평가가 가능한 모형이다. 이를 위해 국내정보통신 벤처기업들을 대상으로 FGI(Focus Group Interview)를 실시하여 경제성 평가모형 구축에 필요한 항목들을 찾아내고 이를 바탕으로 경제성 분석 모형을 개발하였다.
