Since many accidents have occurred in Korea in these days, many people have lost their health and have been damaged. The damages caused by fires which occur to many buildings where many people always reside takes a substantial share of the total damages. And since the proportions of the domestic fire protection designing/supervising industries are relatively much disregarded compared to other kinds of work, it is in the situation that there are many cases of serious damages because the fire protection equipment didn't exert the proper functions on fire after a building is constructed since the supervision against the poor construction along with the inadequate design. In order to improve such situations, in case of the design industry, the criteria on registration and workforce placement, the scope of operation, the design documents required when requesting the agreement to the construction permits, the responsibilities and authorities about the jobs of the fire protection facility designers must be improved and, in case of supervising industry, the registration criteria, the operation scope and the kinds, methods, targets and criteria of supervision, the criteria on the additional placement of assistant supervisors, the contents and scope of work must be improved, the PQ system and Public Supervision System must be reviewed and the systems for preventing any poor supervision must be improved in order to pursue the security of the people and their properties at the same level as the other kinds of work by preparing for the firm position and foundation of the fire protection design and supervision.

We explore how stock returns and volatility have been impacted by securities market stimulating and controlling plans during the 1980-2004 period, using return analysis, event study, and BFL tests. First, we examine effectiveness of the stimulating plans for a depressed market and the controlling plans for an overheated market with respect to different firm sizes and industries as well as the whole market. KOSPI, large-sized, finance, and manufacturing company stock prices significantly rise following stimulating plans, implying that the plans are quite effective. Controlling plans also seem effective as stock prices stop rising and tend to decline following the plans. Second, we test whether securities market plans have any further impact with respect to fun sizes and industries in addition to the impact on the entire market. Only large-sized stocks show additional response to stimulating plans, while small-sized, electrical-electronic equipment, distribution, and manufacturing industries are further impacted by controlling plans. Third, the results of BFL tests show that volatility does not change around the announcement dates of stimulating and controlling plans. It appears that securities market plans have no impact on volatility. Only stock returns respond to the plans.

Generally, electricity market has monopoly market structure because of need of enormous investment for infrastructure. However, the introduction of competition in network industry as electricity is a tendency of the world with decreasing the effects of economy of scale due to the advancement of technology. Now, electricity industry restructuring is in progress but the competition in electricity retail market is not in force yet in Korea. Whether a effective competition exist or not is very important to policy decision maker who drive restructuring, but there are small numbers of quantitative researches on that. In this study, we estimated the effectiveness of competition in the electricity retail market through switching costs. If switching costs are high, consumers actually can be locked in incumbent firm in spite of introduction of competition. Therefore switching is a critical factor to determine effectiveness of competition and to estimate the size of switching costs quantitatively can proffer the information about whether the competition in the electricity retail market is effective or not in the future. We estimated switching costs using consumer' stated-preference data by conjoint analysis. In according to estimation results, the cost of switching process is not so high, but the relative brand loyalty of an incumbent company is significantly high. And the price is considered as the most important factor choosing an electric service commodity. Based on the empirical results, it is possible to analyze the relationship between suppliers' competitiveness resulted from management efficiency and customers' switching possibilities. The paper therefore provides guidance for suppliers in deciding to enter into retail competition and for policy makers in introducing retail competition. And it has a significance of estimating the switching costs directly.

The purpose of this study is to investigate the effects of public R&D subsidies on private R&D. We have analyzed rationales for the public R&D subsidy from different perspectives. On the basis of literature review, a two step research model is constructed: participation phase (when firms benefit from public subsidies) and decision phase (when firms make decision on additional R&D investments). Using propensity score matching(PSM) method, we compare the potential outcome of the treated group to a matched controlled group of non-subsidized firms. The data used in this paper was collected from various sources. The Korean Innovation Survey 2008(manufacturing sector) is a main source of data. Financial data such as revenue, asset and capital stock, and number of employees were supplemented from the Nice Information Service KIS Value database. The R&D survey, conducted by MEST(Ministry of Education, Science and Technology) each year, was also used for the R&D expenditures of the manufacturing firms. This study comes up with the following empirical results. First, a firm's innovation capability, financial constraints, and sector appear to influence the selection of firms who were benefited from government's financial supports for R&D. Second, empirical results show that public R&D funding complements private investment on average and appear to have perpetual effects on the following year. Finally, sectoral difference in the effect of public subsidies on firms' R&D investment was confirmed. In addition, SMEs show more positive effects than large firms.

Internet was first designed only for sending data, but as the time passed, internet started to evolve into a broadband multi-media web that is capable of transmitting sound, video, high-capacity data and more due to the demands of internet users and the rapid changing internet-communication technology. Domestically, in January, 2000 Saerom C&T, launched a free VoIP, but due to limited ways of conversation(PC to PC) and absence of a revenue model, and bad speech quality, it had hit it's growth limit. This research studied VoIP based on technological enhancement in super-speed internet. According to IDC, domestic internet market's size was 80,800 million in 2008, and it formed a percentage of 12.5% out of the whole sound-communication market. in case of VoIP, it is able to maximize it's profit by connecting cable and wireless network, also it has a chance of becoming firm-concentrated monopoly market by fusing with IPTV. Considering the fact that our country is insignificant in MVNO revitalization, regulating organizations will play a significant roll on regulating profit between large and small businesses. Further research should be done to give VoIP a secure footing to prosper and become popularized.
