  • This paper presents the framework for analysis of small-signal stability. In this framework the equilibrium points of system DAE model are traced using continuation method and instability points are determined on the solution path. Especially Implicit shift QR-modified Arnoldi method is utilized to calculated the rightmost eigenvalues. Small-signal stability is becoming one of the major factors that affect the ATC in the environment of deregulation. Stability limited ATC is easily evaluated in this stability analysis process.

  • Historically shipping conference has enjoyed antitrust immunity in consideration of the importance of liner service in international trade in that it is essential to ensure stable movement of international freight. However, shipping deregulation which has been carried out for last decades in the US and EU has caused significant changes to the liner shipping market. In fact, most of shipping conferences have broken up or transformed as discussion agreement since shipping regulatory reform. However, on the other hands, it is also true that it has contributed to developmore efficient and responsive negotiating process that are better tailored to the needs of individual shippers.

  • Creeping bentgrass (Agrostis stolonifera L.) is economically important as the principal turfgrass species for golf course greens and fairways in temperate climates around the world. As the utilization area of the turfgrass species increases recently, the demand for new and improved cultivars increases. Thus, substantial progress has been made in applying modern biotechnology to develop genetically engineered (i.e., biotech) creeping bentgrass with new traits that eluded the breeders. This review article addresses the advances made in developing biotech creeping bentgrass, which are categorized in the following topics: (i) genetic transformation of creeping bentgrass, (ii) development of various biotech creeping bentgrasses by genetic engineering, and (iii) progresses in the deregulation of herbicideresistant creeping bentgrass.

  • In Korea large scale land development projects have been initiated, in general, by public sector. Due to the on-going liberalization and deregulation trends, however, the need for the land development by private enterprizes is growing very fast. Nontheless, the present situation including institutional setting is not favorable enough for the private participation. The purpose of this study is to provide necessary strategies for vitalizing private participation in the land development. The main contents of this study are devided into four parts. First, the background logic of the private participation in land development is investigated theoretically through reference review. Second, the present situation especially in terms of institutional aspects in analysed and criticized. Third, similar experiences of foreign countries, such as Japan, Germany, France, England, are reviewed in short. Finally, some measures and strategies for improving the present institutional settings are provided and recommended. These include the simplification of the complicated planning system, alleviation of the restraints against private land development, diversification of land development methods and etc.

  • In the aftermath of the financial crisis of 2008, while numerous members of the general public lost their homes and jobs, many of the largest banks held responsible for the crisis have been successfully rescued by bailouts. In this paper, through the analysis of income inequality, unemployment, tax cuts, and bailouts, we show that the interests of the general public are different from the interests of politicians and bankers. While the small elite group of politicians and bankers could set the deregulation policies with inordinate power based on full information, most people were ignorant and unconcerned about the policies, and hence did not oppose them. Specifically, we model the credit change in the financial markets of the United States by a finite state machine, and design three local supervisors representing three groups with different interests. It is then shown that the deregulation policies were adopted according to the difference of the supervisors' powers.

  • In terms of deregulation requests from business, incidents at construction sites are rapidly increasing after reducing the regular safety training hours. Especially, to prevent incidents through safety trainings for construction site workers, who have lots of hazardous tasks than general manufacturing, is not only to protect property of both the companies and the country but also to increase their profits. That is why there are loud voices regarding that the safety training is a core mandatory to prevent industrial incidents. But, most companies, as soon as the deregulation for safety training is implemented, mitigated conducting safety trainings to prevent incidents. With this, theincidents are currently to be increased and caught in a vicious circle of many incidents at the smaller companies because of their absentmindedness regarding safety training due to their poorness as subcontractors of major companies, comparing to major companies. This study explains that incident factors are roughly divided into technical factor, managerial factor, and educational factor. And, we confirmed that the educational factor led by deficiency safety awareness and knowledge was the major factor.

  • So many countries, including England & Wales. USA, Australia, New zealand. Canada and Korea. now undergo deregulation process in the power system sector. Therefore. new terminologies in this field are generated more and more. It is the same case in our country. However the meanings and uses of these terminologies are so confused. This paper proposes standardization, refinement and explanation principles of new terminologies in electric power deregulation.

  • The deregulation problem has recently attracted attentions in a competitive electric power market, where the cost must be earmarked fairly and precisely for the customers and the Independent Power Producers (IPPs) as well. Transmission loss is an one of several important factors that determines power transmission cost. Because the cost caused by transmission losses is about $3{\sim}5%$, it is important to allocate transmission losses into each bus in a power system. This paper presents the new algorithm to allocate transmission losses based on an integration method using the loss sensitivity. It provides the buswise incremental transmission losses through the calculation of load ratios considering the transaction strategy of an overall system. The performance of the proposed algorithm is evaluated by the case studies carried out on the WSCC 9-bus and IEEE 14-bus systems.

  • With CB data in South Korea, this study examines whether the credit risk of borrowers changes when the regulation on bank mortgage supply is relaxed. We analyze the effect of deregulation on LTV and DTI limits in the Seoul-metropolitan area in August 2014 with a difference-in-difference approach. We find that the probability of delinquency is lower in the Seoul metropolitan area after the deregulation than in other urban areas. The effect is noticeable among low-income and low-credit borrowers. We also find that borrowers change their debt structure to reduce the interest costs utilizing their improved access to bank mortgages. The findings suggest the necessity to consider the burden of the high interest costs of unsecured loans for debtors with low incomes and low credit ratings in designing housing finance regulations.
