Most old apartment housing have been replaced with new ones by means of the reconstruction. But with the change of the construction environment, remodeling is introduced as a new alternative for the replacement. Remodeling is expected to reduce national loss owing to the early reconstruction of old apartments resulted from economical and functional deterioration. But there still remains a lot of problems to be first solved for Remodeling. One of those is to figure out how to perform an economic feasibility analysis effectively. The researches of remodeling done under the rally stage are not sufficient in economic feasibility for apartment housing. Therefore, this paper suggests an effective method for the economic evaluation of remodeling projects focusing on a rental high-rise apartment.

The aim of this study is to examine the relative economic benefits between the septic tank and exclusive sewage pipe line in designing the large building at combined sewer districts. With the case study of Lotte World Tower Building, we analyze a cost-benefit between two alternatives. The research results showed 2 years of payback period, about ￦6.17 billion of NPV, and 1.93 of B/C ratio for installing the exclusive sewage pipe line in comparison with septic tank. This results provide useful guidelines for policy establishment of the septic tank closure and for plausibility of installing exclusive sewage pipe line when constructing a large building. In the future, it will be necessary to consider additional cost-benefit analysis including burden charge borne by causers, the burden of management responsibility with a exclusive sewage pipe line, and the economic benefits of reducing odor.

This study reviews articles published in the Review of Social & Economics Studies and presented at many research conferences organized by Korean Association for Political Economy(KAPE). The purpose of this review is to retrospect such research activities of KAPE and to make a step forward to relevant research on Korean Economy. Considering current economic depressions and the crisis of academic science in general, the responsibilities of researchers as a economist are heavier than ever. To break through these difficulties, we have to inspire and organize research activities at KAPE level above all things. At the individual level, we should attend objective analysis and propose alternatives to Korean economy in the lights of reform and progress viewpoint.

지난 3월에 발효된 기후변화협약의 목적은 이산화탄소 등의 온실가스 배출을 억제하여 지구온난화를 방지하자는데 있다. 그런데 이산화탄소의 배출을/억제하기 위해서는 화석연료의 사용을 줄일 수 밖에 없고 나아가서는 경제성장목표를 수정하지 않을 수 없을 것이다. 이산화탄소 배출저감을 위한 여러 정책대안들 중에 탄소세가 가장 효과적이며 시행가능성이 높은 것으로 알려져 있으며 EU를 비롯한 선진국들을 중심으로 범선진국 차원에서 이를 도입하자는 움직임이 있다. 특히 우리나라는 OECD가입을 목전에 두고 있어 다른 선진국들과 마찬가지로 탄소세의 도입을 적극 검토하지 않을 수 없다. 이에 본 고는 원유환산배럴당 10달러의 탄소세를 부과할 때 우리나라 각 산업부문에 미치는 영향을 산업연관모형 및 정태적 무역모형을 이용하여 추정하였다. 그 결과 우리나라 산업전반에 걸쳐 탄소세의 영향이 상당히 크게 나타났으며 특히 시멘트, 철강, 화학 등의 에너지 다소비 업종을 중심으로 심각한 대외경쟁력 약화 및 수출감소가 추정되었다.

지난 몇 십년동안 전 세계적으로 제조기술 분야의 급속한 성장으로 대부분의 제조업에서 눈부실만한 품질향상과 생산성 극대화를 이루어 왔다. 하지만 현재 제조기술 분야는 새로운 문제에 직면하고 있다. 실제 현장에서 관리하고자하는 품질특성은 정규분포를 따르지 않는 경우가 많은데, 대부분의 통계적 공정관리기술체계가 정규분포를 기반으로 하고 있다는 것이다. 이러한 이유로 비정규 공정에서 극소불량관리, 미세변동관리에 대한 연구가 시급한 실정이다. 하지만 비정규 분포를 통계적으로만 해석하고 설계하기 위해서는 현실적으로 한계가 있으며, 경제적 설계의 접근방법이 또 하나의 좋은 대안이 될 수 있다. 본 논문에서는 비정규 공정에서 관리도의 경제적 설계를 위한 연구동향을 살펴보고 추후 연구방향에 대해 제시하고자 한다.

수도권 부하의 집중과 원거리 발전단지 위치는 우리나라 전력전송의 문제점이며, 전압형 HVDC 적용이 전력전송 문제의 대안이 되고 있다. 초기투자비가 높은 전압형 HVDC 사업의 경제적 타당성 확보의 방법은 기존 시장접근법의 부가가치 편익반영 외에 다른 각도의 다양한 편익산정법의 제안이 필요하다. 본 논문에서는 전압형 HVDC 사업 타당성 확보를 위한 피해비용저감방식의 다양한 편익을 도출하고 경제적 타당성을 제시하였다.

2012년 12월 사회적 경제 촉진 방안으로서 협동조합 기본법 제정 이래 3차에 걸린 개정을 해왔으며, 협동조합 중 소상공인협동조합의 경쟁력 강화와 자생력 제고를 위해 정부 및 지자체의 지속적인 경제적, 교육적 지원 노력에도 불구하고 현실은 소상공인협동조합의 영세성과 최근의 COVID-19사태 등 소상공인협동조합의 경제적 활로 개척 등이 쉽지는 않은 실정이다. 본 연구는 기존의 소상공인협동조합 관련 문헌 연구를 기반으로 하여 소상공인 관련 전문가 집단의 FGI를 통해서 소상공인협동조합의 현실적 어려움에 대한 대안적인 정책들을 수립하고자 한다.

The paper suggests risk management methodology for alleviating casuality accidents at urban railway stations. Risk management deals with countermeasures for reducing accident probability or consequences to reach at the certain level of risk. First of all, Economic evaluations using cost and benefit for all the alternatives are performed. The alternatives exceeding B/C ratio greater than 1, each alternative is applied in the order of higher B/C ratio. this process is repeated when the level of risk is reduced as low as reasonably practical (ALARP). In order to determine the level of ALARP, Level of Service (LOS) for casuality risk at urban railway stations is proposed. The ALARP level is set to the LOS "C". Finally, a case study is applied to the Jongno 3-ga station, which is a highest risky station among all the stations operated by Seoul Metro and Seoul Metropolitan Rapid Transit Cooperation (SMRT).

The Korean government establishes a strategy to develop the Busan New Port as a world ranking two transit-oriented port. This paper aims at presenting an efficient inter-terminal transport (ITT) system in the Busan New Port as a method of achieving the government strategy. First, it presents results of long term forecast for the inter-terminal transportation volume in the port. Second, it proposes two systems to treat ITT in the port; Double stack Multiple Trailer System (DMTS) and Rail-based transportation system. The implementation methods in the port are introduced in detail for the both systems, and the required number of the systems and costs are calculated for implementation of both the systems. B/C for DMTS is analyzed to 3.7, moreover unit-fare per [$ton{\cdot}km$] can is lowered to 67% against current fare. DMTS is shown to highly potential for efficient ITT in the port.

Because of the recession of the world economy, small businesses face with many problems in securing their required labor force, capital, technology, among others. As an alternative to address those difficulties, there is a research to introduce the "sharing economy", which shares and changes resources. However SMEs have difficulties in actually introducing the sharing economy and the introduction of inter-company because sharing economy business models do not exist. This research has presented the business model for the sharing economy that is necessary in the introduction and operation of the said economy among SMEs. In order to design the business model for the B2B sharing economy, this research has drawn the components needed to design the business model through a preceding study on existing business models. Based on this and the preceding study, this research has presented the business model, which can be introduced to the sharing economy among SMEs. In addition Business model presented in this study will be a guideline for introducing shared economic conditions for each SMEs.
