Recently, in the space market, there has been a rapid reduction of the launch price. The major reason is that a few commercial companies, especially SpaceX, began to enter into the space market about ten years ago, which has changed the space market from monopolization to competition, and accelerated the adoption of commercial efficiency in the technology and management. Also, the successful landing and recovery of a first stage in 2016 by SpaceX proved to be a prelude to opening a new era of reusable launch vehicles, and SpaceX declared the groundbreaking launch price through using the reusable launch vehicle. This study calculates the total launch cost required to put a certain satellite into the LEO, compares the launch cost in three cases with different payload weights, and reviews the impacts of the payload on the cost effectiveness of a reusable vehicle. The total launch cost is divided into 6 subsections cost, namely development cost, production cost, refurbishment cost, operation cost, fixed-cost of factory and launch site, and insurance cost. The cost estimation relationships used in the calculation are taken from the commonly proven cost models such as TRANSCOST.

When assessing environmental or other regulatory programs, economists and other policy analysts have traditionally used the approach that consists of comparing the benefits from regulation with the costs that must be borne to capture these benefits. The vast majority of economic analysis of regulation was based upon the assumption that regulations increase production costs. Porter had disputed this seemingly straightforward claim. In his view, economists had failed to incorporate the capacity of stringent regulations to induce innovation into their analysis. However, at the same time, the hypothesis had been criticized by economists. This study analyzed the determinants of innovation performances as well as activities of small and medium manufacturers, based on a recently held survey among mainly manufacturing SMEs in Korea. In particular, this study took the level of innovation activities, the strength of environmental regulations, and moreover the impediment that the company went through as factors. In addition, the characteristics of innovative SMEs were compared with the other counterparts. The empirical analysis revealed that the level of environmental awareness, existence of innovative activities, characteristics of firms, and moreover the innovation types are the most important determinants of SMEs’ innovation performance both in technology as well as in economic perspective.

The MBR technology has evolved rapidly over the past two decades with significant gains in performance and reliability, and reductions in costs. Membrane bioreactors (MBR) technology is widely recognised as offering a key option for enhanced wastewater treatment or reuse. The objective of this paper is then to critically review the remarkable achievement on the research and commercial applications of membrane bioreactor (MBR) technology and to present current and potential MBR markets on a global scope. This brief review of the technology incorporates five key aspects : 1) evolution of MBR practice, 2) the commercial technologies of MBRs, 3) the largest MBR installations globally (e.g. > $10,000m^3/day$), 4) MBR market growth, and 5) directions for future research. Finally, the development directions of economical, environmental and technical aspects in MBRs; 1) investment costs; 2) effluent water quality; 3) membrane materials and modules; 4) MBR equipment and treatment process; 5) operating costs (higher energy & chemical consumption); and 6) sustainability such as anaerobic MBRs in the coming years were addressed.

The primary purpose of ITQ (individually transferable quota) is to reduce the overcapitalization problem in the open-access fishery. It has been argued that the least cost-efficient vessels under ITQ may exit first from the fishing by selling their quotas, thereby also reducing the excess capital. The purpose of this paper is to provide a case when ITQ may prompt the exit of less cost-inefficient vessels in the presence of irreversible exit cost which is proportional to the cost-inefficiency. Real option model is adopted in order to analyze the source of hysteresis associated with fishery exit decision. By linking the interaction between vessels' adjustment costs, cost-efficiency of harvest and uncertainty of fishery return, we show that cost-inefficient vessels will not exit always first from the fishery in contrast to the conventional wisdom. Relevant policy implications is discussed.

Heavy oil residue upgrading process was being used in conventional refinery process. Recently, as the importance of non conventional energy development is growing up, the commercial projects of heavy oil upgrading are getting more active than before. For having competitive business model in the resource competition, non conventional energy development should be considered as an important business strategy. In developing oil sands, extra heavy oil, and shale gas, canadian oil sands and extra heavy oil have great importance in substitution of conventional oil consumption. In oil sands development, the bitumen, which is extracted from oil sands, has great value after upgrading or refining process. Similar process is being used current conventional refinery process. The bitumen is highly viscous hydrocarbon. This bitumen includes impurities which can not be treated in conventional refinery process. As this reason, specified process is needed in bitumen or extra heavy oil upgrading process. Moreover, there will be additional specified facilities in the process of production, transportation and marketing. In oil sands, there are various kinds of commercial upgrading process. Extraction, dilution, coking and cracking method were being used commercially.

국제경쟁력 향상을 위한 주요채택전략으로 유연자동화제조시스템의 보급이 급격히 확대되고 있다. 그러나 시스템의 개발.제작과 운영을 담당할 기술자,기술관리자 및 고급기능인의 확보가 전제되지 않는한 성공적인 투자를 기대할 수가 없다. 본 논문에서는 이러한 담당자 양성시 필수과정인 연구개발실험 및 운영실습에 사용될 적정한 유연자동화제조시스템의 개발과정중 일부인 개념설계 및 Layout내용을 정리하여 보고한다. 기본적으로 적정비용으로 일반산업용과 동일한 기능 (Hardware는 경절삭산업용, 소프트웨어는 일반산업용)을 갖춘 시스템으로서 실험 침 실습에 들어가는 비용도 최소화할 수 있도록 설계한다. 또한 System Controller는 시스템 성능향상과 무인가동시간확장에 필요한 소프트웨어 (공구상태감시, 자동측정 및 보정,Dynamic Scheduling등) 의 개발과 실험이 용이하도록 구성하고,산학연 공동연구체제를 구축하여 지속적인 개발이 가능케 한다. 필요시 모든 Source Program도 공개할 예정이다.

물 분쟁은 더 이상 다른 나라의 이야기가 아니다. 우리나라 역시 산업구조의 변화와 인구의 증가로 물의 수요가 증가함에 따라 많은 물 분쟁이 발생하고 있다. 물 분쟁은 많은 원인과 다양한 차원의 분쟁주체들이 관계하고 있어 복잡한 네트워크구조로 나타나는 특징이 있다. 이러한 다양한 종류의 물 분쟁을 해결하기 위해서는 그 대책 또한 법률적, 기술적, 사회적으로 다양하게 접근 하여야 할 것이다. 그러나 과거 우리나라의 경우 분쟁이 발생하였을 때 그 분쟁의 최후 결정은 주로 사법기관에 의하여 처리되곤 하였다. 이러한 사법적 분쟁해결은 많은 시간과 비용을 필요로 하며 분쟁당사자 모두 만족할 수 없는 결과를 야기 할 수 있는 큰 단점을 안고 있다. 본 연구에서는 이러한 단점을 보완하고 물 분쟁을 해결하기 위한 방안으로 대안적분쟁해결방안(ADR: Alternative Dispute Resolution)을 소개하고, 적용가능성에 대하여 검토하였다. 물 분쟁의 해결을 위해 ADR을 활용한다면 시간과 비용의 절약, 원만한 분쟁해결, 사후에도 당사자들의 좋은 관계 유지 등의 이점을 기대 해볼 수 있다.
