While promoting a variety of projects by using sea space, there has been a lot of social controversy among the stakeholders based on the results of the analysis. In particular, the benefits of fisheries sector were over-estimated and occurred a lot of opposition from fishermen and environment groups. In order to this solve, we have been studied focussed such as excavation of new projects, the method and result of the estimated benefits for fisheries sector. With regard to the tidal power plant of Garolim, we came up with five kinds of problems such as doing not reflect of the cost of the initial investment, over unit production, over unit price, excessive selection of breed, issues of cost of production in benefits study of fisheries sector derived previously. In order to these problems, we have derived new profitable projects based on the initial materials such as improvement of raising breed, discharge project of fingerlings and a small sea ranch project. As a result, previous study was analyzed in 30.2 billion won(1993), 54.8billion won(2009), but this study was estimated to 26.4 billion won and differences of benefits amount were occurred. In a previous study was calculated benefits by simple method, but this study came up with new projects for fisheries sector and because we estimated benefits considering new project. The method for benefits calculations for fisheries sector was not attempted in previous studies and in this study, we approached for the first time Also, in this study suggested new method to increase incomes fishermen such as development of suitable ranch breeding for the marine environment, ranch license(limited license), development of fisheries resources and the operation of fisheries facility. In the future, we hope to be helpful for the same field of study.

Construction contactors must continuously seek to improve their cash flows, which reside at the heart of their financial success. They require careful planning, analysis, and optimization to avoid the risk of bankruptcy, remain profitable, and secure long-term growth. Sources of cash include bank loans and retained earnings, which are conceptually similar in that they both incur a cost of capital. Financial management therefore requires accurate yet customizable modeling capabilities that can quantify all expenses, including said cost of capital. However, currently existing cash flow models in construction engineering and management have strongly simplified the manner in which interest is assessed, which may even lead to overstating it at a disadvantage to contractors. The variable nature of cash balances, especially in the early phases of construction projects, contribute to this challenging issue. This research therefore extends a new cash flow model with an accurate interest calculation. It utilizes singularity functions, so called because of their ability to flexibly model changes across any number of different ranges. The interest function is continuous for activity costs of any duration and allows the realistic case that activities may begin between integer time periods, which are often calendar months. Such fractional interest calculation has hitherto been lacking from the literature. It also provides insights into the self-referential behavior of compound interest for variable cash balances. The contribution of this study is twofold; augmenting the corpus of financial analysis theory with a new interest formula, whose strengths include its generic nature and that it can be evaluated at any fractional value of time, and providing construction managers with a tool to help improve and fine-tune the financial performance of their projects.

Selection of profitable research and development (R&D) projects is one of the major factors affecting sustained growth of firms and countries. This paper analyze what influences the knowledge on the business model exerted on selection of a R&D project. A business model converts the technology value to the customer value, and comprehensively describes the target customers for commercializing a new technology, core values, behaviors within organizations, resources, and external partners. Thus, understanding a business model would make R&D project evaluators place the feasibility and profitability of the business above the merits of the proposed technology in evaluating the technology development. To verify this hypothesis, we had 78 R&D project evaluators acquire the knowledge on the business model and measured how their criteria for R&D project selection have changed using the AHP method. The results shows that feasibility and profitability are more important than the merit of proposed technology, especially capability of company and business development are more important than the levels of technology innovation.

This paper explores what we call 'the problem of undone social science' by examining the lack of interests in the social, ethical, and legal issues of synthetic biology among social scientists in Korea. This new field of science, which has emerged in the twenty-first century with the promise of solving future problems of energy, food, and disease in the world, has also created a considerable degree of anxiety over the issues of bioethics, biosafety, and biosecurity. From its beginning, therefore, researchers of synthetic biology in Europe and the U.S. have sought to engage social scientists in their projects. Yet scientists and social scientists in Korea have shown no sign of working together to deal with both potential benefits and risks of synthetic biology. Why this silence? What strategic moves would be needed to overcome the structural barrier for their collaboration? Surveying the diverse methodologies developed during and after ELSI (ethical, legal, social implications) experiments, this paper aims to provide three suggestions that might make possible mutually profitable and continuously stimulating dialogues between the two worlds of science and social science: first, institutionalize the ELSI studies on any newly emerging science and technology of concern; second, explore diverse post-ELSI methodologies experimented elsewhere and develop ones that might be applicable best to the Korean situation; and third and perhaps most important, create an intellectual space and a lawful protection for social scientists to exercise their research freedom at the reasonable level and receive a fair review by their peers, not solely by funding agencies and scientific organizations.
