The Fukushima Nuclear Disaster in 2011 and California Power Failure in 2001 are examples of the importance of the power plant safety management that caused huge national loss with a power-related mass casualty incident. In a situation where humans cannot live without electricity, efforts to strengthen the systematic firefighting safety management in power plants that produce electricity with large amounts of hazardous materials as fuel, such as nuclear energy, coal and gas, are essential to protect life and prevent property loss and stable economic growth from fire explosion accident or radiation leak due to the negligence of safety management and natural disasters such as earthquakes, which has recently become an issue. This study examined the operating situation of firefighting safety management in power plants with firefighting officials employed by five power generation companies including Korea Southern Power Co., Ltd. and Korea Hydro & Nuclear Power Co. Ltd., which are in charge of the domestic power supply. As a result, for the systematic firefighting safety management of power plants, improvement plans were drawn, including the development of an effective business manual and a comprehensive management system, the substantiality of firefighting safety education, and the strengthening of seismic designs to prepare for earthquakes.

인터넷기업들은 불과 몇 달 전만 해도 수수께끼로 가득 찬 요지경이었다. 매출액은 늘어났지만 더 많은 손실이 발생했고, 엄청난 적자와는 정반대로 주가는 연일 상승곡선을 그리고 있었다. 오히려 손실을 줄이는 방안을 발표하면 주가가 떨어지는 기현상마저 보여 구경제의 질서에 익숙해 있던 투자자들이나 경영자들을 혼란스럽게 만들고 있다. 그런데 이처럼 높게 평가되던 인터넷 기업들의 주가가 최근에 들어 폭락하고 있다. eToys의 경우 주가가 최고치 였던 ＄86에서 94% 폭락한 ＄4.75에 거래되었고, CDNow는 83%, Buy.com은 81% 등 주요 온라인 업체들의 주가가 80% 이상 하락하였으며 그 외의 적지 않은 인터넷 기업들의 주가 역시 전성기에 비해 90-95%까지 폭락하였다. 이러한 이유로 최근 인터넷기업들의 정확한 가치평가를 하기 위한 연구들이 시도되고 있으며, 이러한 시도 중 비교적 객관적인 정보인 재무정보들을 이용하기 위한 연구들도 있다. 하지만 아직까지는 우리나라의 재무제표들이 제공하는 정보들이 부족하고 IMF이후 비정상적인 주가 등으로 인하여 실증하는데 어려움이 따르고 있다. 또한 인터넷 기업들은 전술한 바와 같이 기존 오프라인상의 제조업형태의 기업들처럼 일반적인 재무제표분석을 통한 가치평가에 어려움을 겪고 있다. 하지만 인터넷을 기반으로 한 디지털 경제에서도 오프라인기업에서와 똑같은 현상이 발생한다는 사실을 간과해서는 안 된다. 현금지출이 도달 가능한 현금유입의 수준을 넘어선다면 결국 도산하는 것은 인터넷기업들도 마찬가지이다. 현재 어떤 기업에 투자하는 것은 그 기업의 미래 현금흐름을 구매하고자 하는 것이다. 따라서 미래의 현금흐름이 커질수록 그 기업의 가치는 상승하게 된다. 현금흐름 분석이 특히 중요한 이유는 기업의 미래 현금흐름을 기업의 타인자본비용과 자기자본비용의 조합인 기회자본비용으로 할인함으로써 현재의 기업가치를 구할 수 있기 때문이다. 이처럼 기업이 영업활동이나 투자활동을 통해 현금을 창출하고 소비하는 경향은 해당 비즈니스 모델의 성격을 규정하는 자료도로 이용될 수 있다. 또한 최근 인터넷기업들의 부도가 발생하고 있는데, 기업의 부실원인이 어떤 것이든 사회전체의 생산력의 감소, 실업의 증가, 채권자 및 주주의 부의 감소, 심리적 불안으로 인한 경제활동의 위축, 기업 노하우의 소멸, 대외적 신용도의 하락 등과 같은 사회적·경제적 파급효과는 대단히 크다. 이상과 같은 기업부실의 효과를 고려할 때 부실기업을 미리 예측하는 일종의 조기경보장치를 갖는다는 것은 중요한 일이다. 현금흐름정보를 이용하여 기업의 부실을 예측하면 기업의 부실징후를 파악하는데 그치지 않고 부실의 원인을 파악하고 이에 대한 대응 전략을 수립하며 그 결과를 측정하는데 활용될 수도 있다. 따라서 본 연구에서는 기업의 부도예측 정보 중 현금흐름정보를 통하여 '인터넷기업의 미래 현금흐름측정, 부도예측신호효과, 부실원인파악, 비즈니스 모델의 성격규정 등을 할 수 있는가'를 검증하려고 한다.

In this paper, we present a literature review of the mechanisms and methodology for technology spillover, in order to provide a theoretical and practical foundation for estimating the technology spillover effect of public funded R&D programs. Our research consists of four parts. First, we investigate what technology spillover is and how it works. Second, we review the methodology used to empirically measure technology spillover, with a view to understanding the advantages and disadvantages of each method. Third, we identify the gap between the spillover phenomenon and its estimated results, caused by the limitations of the methodology, and discuss the challenges in measuring technology spillover. Finally, we present several considerations to improve the measurement of technology spillover in the context of public funded R&D programs. Our paper provides policy makers and researchers with basic knowledge about technology spillover and helps them suitably evaluate the results obtained from the literature review. In addition, it contributes towards improving the existing methodology by recognizing the gap between the spillover phenomenon and the methodology.

In spite of the increasing importance of service sector, most previous studies on schumpeterian hypotheses originated from manufacturing firms that have the needs to invest heavily in research and development (R&D). Conversely, we investigated the relationship between technological innovation activity and size of firms using panel data. Results of the analysis, the following results were obtained. First, the details depending on the industry sector was divided into active and vigorous industry technology innovation activities did not. Second, the relationship between firm size and technological innovation activity may not be, depending on the industry, some of the U-shaped model, may be. Third, showed fewer intangible assets, more debt, larger exports which further promote the technological innovation activities in industry. Finally, the relationship is responsive depend on the firm size variable.

This study provides a effective approach to the construction management problem with the limited number or amount of available resources using the analytic hierarchy process. Construction management is a series of decision making processes for planning and controling of cost, time and quality as main objectives in construction works. When several activities need the limited same resource at the same time, it is very hard to decide the priority of the activities in the real situations. For that the scientific decision making method and procedure for resource allocation are required. This study solves the resource allocation problem by dealing with the decision making problem which the activities are distributed to multiple projects and under multiple criteria. The analytic hierarchy process is a method devised to solve complex multi-criteria decision problems. The result shows that this study can be effectively used to make decisions in situations involving multiple objectives by evaluating the prioritized ranking and degree of the activity alternatives based on the overall preferences.

Tipping takes significant part in hospitality industry, especially in hotels and restaurants. According to the recent studies, over US$26.4B were given to the service personnel in the restaurant industry from the customers as tips in 2003 in the US alone. As a result of these developments, tipping has been a legitimate area of academic inquiry in many foreign countries but here in Korea this custom has not drawn much attention due to service charge being placed by the government since 1979. The purpose of this study is to analyse the perception and attitude of tip recipients and compare it with the results of previous studies carried out by Shamir and Parrett. Statistical analyses were carried out to compare the differences of perception between tip recipients and non recipients on the staff role conflict, job satisfaction, pay satisfaction and attitude toward the guests. It is suggested from the finding that the current service charge system needs to be taken into consideration for possible revision or alteration as the management environment and customer needs in the hospitality industry in Korea are changing at an enormous pace. As this study focused on the perception of employees, further study on the perception of customers to tipping is highly recommended.

This study aims to identify early retirement and the subsequent career ending patterns and explain the phenomena in terms of social security policies and labor market perspectives. Although many older workers retire early, there are very few studies to examine how the retirees end their careers after quitting the long-time jobs. The paper investigates individual work experiences 55 through 61, identifies the career ending patterns, constitutes the micro and macro analytical models to estimate the impacts of labor market and work-related variables. The findings show that many older workers have diverse career ending patterns after long-time career jobs, that is, still working at age-55 job, exiting and reentering, sporadic work, retired permanently from age-55 job, a repeat of labor force entry. Also the estimation results indicate that pension, social security, labor market condition, work structure variables better explain the career ending behaviors than social psychological factors of health, education, attitudes toward retirement and job, ethnicity. Finally, this paper discusses theoretical importances of labor market perspectives and policy implications at the end of thesis.

In 1988, the government provided to the low income people 34.1% of the stocks of Pohang Iron & Steel Company through the People's Share Program of Privatization for the first time, and then in 1989 21% of the share of the Korea Electric Power Corporation were also provided to the low income classes through the same way. The purpose of the People's Share Program was known to be to support the low income classes through participating the profit of public enterprises, and also to expand the capital market through the diversification of stock holding structure. Initially, the government planned that the government share of enterprises such as the Citizens National Bank, the Korea Telecommunication Authority would be sold to the low income classes through the People's Share Program step by step. The income support policy, however, was no longer driven after 1989 when the overall stock prices started to decline. In this paper we tried to measure the effect of the privatization scheme of the public enterprises through the People's Share Program. The problems of the People's Share Program of the Pohang Iron & Steel Commpany and the Korea Electric Power Corperation were also identified. Several implications of the privatization scheme of the public enterprise through the People's Share Program by stages were found. The People's Share Program was found to be a non-stable policy measure for the income support of low income classes. The efficiency impact of the privatization through the People's Share Program was found to be non-significant.

The purpose of this study is to analyze subjective and objective factors for the successful operation of One-Person Creative Firms and find significant variables in accordance with the sales and net profit that are representing business performances. Additionally, we were trying to find that what One-Person Creative Firms have had a government assistance need the supports in order to achieving a good performance in sales and net profit. In the result of this study, the sales volume is related that two(2) subjective(Judgment, Planning) and four(4) objective factors(Patent Application, Patent Registration, Business Duration, Initial Capital). The net profit is related that Challenging Spirits in subjective factors and Run-up to the Business, Business Duration, Initial Capital in objective factors. Ultimately, these factors are important variables for the sales and net profit in relationship both the positive(+) and negative(-). This is an exploratory nature of the study rather than the rigorous hypothesis testing. Therefore, a rigorous hypothesis test study model to derive a more detailed study is needed based on the results of this study in the future.
