KEPCO has been operating a lightning detection network, KLDNet, to cope with lightning-induced faults. An weather observation for last 40 years shows that heavy rainy days per year and the strength of rain have almost doubled. It could be interpreted as more frequent occurrence of lightning events. In accordance with that, the lightning activities and the mischievous influences, such as transmission faults, have increased. In this paper, the observed data by the network in 2007 is analyzed and compared with ten-years-old-statistics accumulated by the former system, LPATS.

We report for the first time the synthesis of niobium dioxide nanowires on a sapphire substrate by chemical vapor transport method. We identified single crystalline nature of as-synthesized nanowires by scanning electron microscopy and transmission electron microscopy. Niobium dioxide nanowires with their large surface-to-volume ratio and high activities can be employed for electrochemical catalysts and immunosensors. The Raman spectrum of niobium dioxide nanowires also confirmed their identity.

Over the past 10 years, AIDS has grown to become one of the major health problems in Korea. This paper reviews the current status of the prevalence of AIDS, AIDS law and policy in Korea. This paper also suggests some proposals for policy to reduce HIV transmission from the view point of personal rights and welfare. Korea needs more effective national AIDS prevention and control programs applicable to the current situations of health policy in Korea. The activities of NGOs would be as important as those of government.

This paper reviews the theoretical background of the entrepreneurship policy recently prevailing in Korea. First of all, we define the entrepreneurship policy as the one that the government increases the supply of the individual entrepreneurs with entrepreneurship and supports their venture creation activities by intervening the entrepreneurial process. We distinguish the entrepreneurship policy from the small and medium-sized enterprises policy and the venture firm policy. As for the legitimacy of the entrepreneurship policy, we introduce the market for entrepreneur, examine the factors resulting in the market failure, and argue the necessity and the principles of government intervention to the market. Based on the entrepreneurial process, we establish the framework of entrepreneurship policy and examine the transmission channels by the policy area. The channels are (1) demand side, (2) supply side, (3) decision-making of establishing a new firm, (4) resources obtaining. Lastly, according to the transmission channels, we classify various entrepreneurship policy tools being presently implemented by the Korean government. However, since this study is a exploratory economic analysis of entrepreneurship policy, the approach and contents of entrepreneurship policy can be varied according to the research agenda and policy intension.

This article reviews the recent activities of field testing and application of superconducting fault current limiters (SFCL) based on high-temperature superconductors (HTS). The review particularly focuses on the trends in the field tests in terms of the technical aspects and commercial activities of the SFCLs. Stimulated by the discovery of HTS, numerous research and development activities have been conducted worldwide for SFCLs operating from distribution voltages to transmission voltages. Different types of SFCLs have been developed and field-tested. Consequently, more than 20 field tests and applications have been performed on real grids worldwide while supplying electric power to the customers. These field tests have not only provided the track records of the operation experiences including the problems and maintenance during operation, but also proved their current limiting capabilities against real faults, rendering this new technology highly viable. Through these activities, the following trends in the status of field testing and application are observed. Resistive-type SFCLs with HTS-coated conductors were dominantly used in the most recent field tests. This implies that the resistive type is technically more mature than the other types. Bus-bar coupling and transformer feeders were the major application locations. It is of importance that most of the field applications were conducted as R&D projects. A relevant change from the R&D stage to the application stage is shown as recently deployed SFCLs are expected to be under long-term operation and commercial service. Here, we review the installation of these SFCLs by substation. This review also discusses the recent activities for their commercial applications.

This study was designed to investigate the effect of silkworm (Bombyx mori L.) powder on lipofuscin, acetylcholine (ACh) and its related enzyme activities in brain of rats. Sprague-Dawley (SD) male rats ($160{\pm}10g$) were fed basic diet (control group), and experimental diets (SWP-200 and SWP-400 groups) added 200 and 400 mg/kg BW/day for 6 weeks. In case of liver membranes, lipofuscin (LF) levels resulted in a slight decreases (4.6% and 11.5%, respectively) in SWP-200 and SWP-400 groups compared with control group. But in case of barin as the most sensitive organ, LF levels were remarkably inhibited about 16.7% and 20.0% in SWP-200 and SWP-400 groups compared with control group. There were no significant differences in acetylcholine (ACh) syntheses as a very important neurotransmitter, and choline acetyltransferase (ChAT) activities as a synthesis enzyme of ACh, and acetylcholinesterase (AChE) activities as a hydrolysis enzyme, which were concerned in transmission of neuron through synapses in brain of SWP-200 and SWP-400 groups compared with control group. Monoamine oxidase-B (MAO-B) activities were significantly inhibited (about 10.2%) in brain of SWP-400 groups compared with control group. These results suggest that inhibiting effects of LF accumulation and MAO-B activity of silkworm powder (SWP) may play a pivotal role in attenuating a various age-related changes for improvement of brain function.

In this study, analysis of disaster relief-related laws and regulations, analysis of disaster relief system, and investigate the inter-governmental relations in disaster relief system through analysis of major disaster relief case. As a result of the analysis, the central government has adjust and coordinate disaster relief activities of the local government, it has been found that you are managing director through the support of the administrative and financial. However, it was found that by weighting the administrative and financial burden on local government in disaster relief activities. In addition, the division of roles between the relief agencies and relief aid agencies of relief supplies transmission on disaster-related laws and regulations have not been specifically explicitly. It was found that has brought the waste of non-efficiency and resources by the duplication provision there is no mutual exchange of information relief supplies transmission situation.

CALS/EC is about doing business electronically. It is based on the electronic processing and transmission of data, including text, sound and video. It encompasses many diverse activities including electronic trading of goods and services, online delivery of digital content, electronic fund transfers, electronic share trading, electronic bills of lading, commercial auctions, collaborative design and engineering, online sourcing, public procuremet, direct consumer marketing, and after-sales service. It involves both products(e.g. consumer goods, specialised medical equipment) and services(e.g. information services, financial and legal services); traditional activities(e.g. healthcare, education) and new activities (e.g. virtual malls). CALS/EC will be emerging to replace and substitute the role of the conventional market. By changing and eliminating some processes of the transactions, the electronic market and the electronic commerce will redistribute the power and hence the benefits of the market activities. Traditional way of doing business may enter into the new electronic market because the role and function of trust and established reputation will be reinforced in the electronic market. The CALS/EC through the Internet has been in the spotlight in the shopping behavior of the consumers. Accordingly Corporates are trying to adapt themselves to those rapidly changing environments being affected by the Internet. Among others, particularly to be noted is the CALS/EC between corporations and consumers whose potential growth can be considered very substantial. This report, focusing on the introduction of CALS/EC for the logistics of SMEs, will allow us to prepare more efficiently for the coming 21st Century. It is obvious that CALS/EC is fast becoming the useful way of exchanging not only information but products in business between firm-to-firm and firm-to-customer.
