70년대 유럽의 선진 복지국가의 위기로부터 확산되기 시작한 신자유주의의 이념적 공세는 베를린 장벽이 붕괴되면서 그 정점에 이른 것으로 보인다. 신자유주의는 국제적으로는 국경의 상호 침투를 통한 범세계적 단일 시장의 형성을, 그리고 국내적으로는 시장의 효율성의 극대화를 주창하였다. 공익산업의 민영화는 정부의 시장에 대한 탈규제 조치의 중심적인 정책이었다. 공기업 민영화의 저변에는 경제 환경의 변화에 따라 초기공기업 설립 당시의 필요성이 소멸되었다는 점과 "정부의 실패"라는 말처럼 공기업 경영상의 비효율성이 놓여 있다. 한국이 직면한 공기업 민영화의 과제를 염두에 두고 공익산업의 민영화에 대한 구체적인 사례를 영국과 미국, 칠레의 경험에서 살펴보면 다음과 같은 시사점을 발견할 수 있다. 첫째, 민영화라고 하는 소유구조의 변경이 경쟁의 도입을 위해 반드시 필요한 요건인지에 대한 의문이다 공기업 민영화가 시장에서의 민간 기업 사이의 경쟁체제를 도모하는 것이지만 공기업 위주의 경쟁체제도 가능하기 때문이다. 둘째, 공기업의 경영비효율성의 원인으로 지적되는 대리인 문제는 민간기업 부문에서도 여전히 발생하는 문제이다. 따라서 민영화라고 하는 소유구조의 개편이 문제 해결의 열쇠가 아니라 효율적기업 감시체제를 도입하고, 경영성과에 대한 규율 및 유인체제를 도입함으로써 책임 경영을 실현하는 것이 관건이라고 할 수 있다.

Preventive maintenance can avail the generation utilities to reduce cost and gain more profit in a competitive supply-side power market. So, it is necessary to perform reliability analysis on the systems in which reliability is essential. In this paper, RCM (Reliability -Centered Maintenance) analytical method is adopted using real historical failure data in Korean power plants. Therefore, the reliability -based Probability model for predicting the failures of components in the power plant is also established, and application to FMECA(Failure Mode Effects and Critical Analysis) consideration of failure probability, Based on the weighting ranking of generating equipments which status to be probability estimation by FMECA. The FMECA is an engineering analysis and a core activity performed by reliability engineers to review the effects of probable failure modes of generating equipments and assemblies of the power system on system performance. The results of this paper show that application of FMECA with stochastic approach to the preventive maintenance can efficiently avail decreasing the cost on maintenance and hence improve the total benefit.

Because the difference between products and services are getting less and less, service and manufacturing companies' efforts are increasingly focused on utilizing services to satisfy customers' needs under today's competitive market environment. The value of services depends on service reliability that is identified by satisfaction derived from the relationship between customer needs and service providers. In this paper, we extend concepts from the fault tree analysis for reliability analysis of tangible systems to services. We use an event-based process model to facilitate service design and represent the relationships between functions and failures in a service. The objective of this research is to propose a method for evaluating service reliability based on service processes using service blueprint and FTA. We can identify the failure mode of service in a service delivery process with a service blueprint. The fuzzy membership function is used to characterize the probability of failure based on linguistic terms. FTA is employed to estimate the reliability of service delivery processes with risk factors that are represented as potential failure causes. To demonstrate implementation of the proposed method, we use a case study involving a typical automotive service operation.

With the advent of industrialization, consumers and end-users demand more reliable products. Meeting these demands requires a comprehensive approach, involving tasks such as market information collection, planning, reliable raw material procurement, accurate reliability design, and prediction, including various reliability tests. Moreover, this encompasses aspects like reliability management during manufacturing, operational maintenance, and systematic failure information collection, interpretation, and feedback. Improving product reliability requires prioritizing it from the initial development stage. Failure mode and effect analysis (FMEA) is a widely used method to increase product reliability. In this study, we reanalyzed using the FMEA method and proposed an improved method. Domestic railways lack an accurate measurement method or system for maintenance, so maintenance decisions rely on the opinions of experienced personnel, based on their experience with past faults. However, the current selection method is flawed as it relies on human experience and memory capacity, which are limited and ineffective. Therefore, in this study, we further specify qualitative contents to systematically accumulate failure modes based on the Failure Modes Table and create a standardized form based on the Master FMEA form to newly systematize it.

This study first attempted to point out fundamental reasons behind the failure to have WiBro services off the saddle, investigating the previous studies, and second to screen the WiBro promotion policies after reviewing the major steps conducted thus far by the government. In order to put the screened policies in order by the importance, an AHP analysis was conducted targeting WiBro professionals in various fields such as government offices, universities, research institutes, and industry. One step further, causal loop diagramming on the system dynamics methodology was conducted to examine the dynamic structure of the WiBro market in holistic standpoint of view. Finally, a simulation model was developed based on the causal loop diagrams and the results of the AHP analysis in order to examine how various policy scenarios influence the growth of the WiBro market over time, and to compare the mix of policy options. Finally, the study attempted to draw some implications for WiBro vitalization.

The present waste problems require a change of thinking with regard to conventional economics. It has been generally believed that competitive markets maximize social welfare. But, the other hand, a few economists argue that "the competitive markets cannot always be relied on to provide all goods in the efficient amount." One of the best examples of the latter contention is the environmental problem. What is the basic thinking of the conventional economics that causes this problems \ulcorner What is the present problem that requires the change of conventional economic thinking \ulcorner The environmental problem result from the conventional economic thinking such as pursuing the limitless of the Gross National Product(GNP), believing the increasing returns in economics of scale and the efficiency of competitive market. This economic principles, howe- ver, does not apply currently to public goods, especially environmental amenity and natural resource because the price of markets does not reflect the natural goods of services. We call this eternality. Externalizes are no considered by either buyers or sellers of goods of which production or use results in an eternality. This leads to market failure are causes an waste problem in the economic activities. Today, it is almost impossible to say in a word what the solution for waste problems is because they are by-products complicated and entangled human activities. In this paper, I have introduced the causes of environmental problems only from the economic point of view. I have also described the needs of conversion of conventional economic thinking. Firstly, sustainable development, maintaining the natural resources, should be the basis of the economic growth rather that pursuing the limitless growth of GNP. Secondly, an appropriate scale of human's production activity should be taken into account to reduce the impact to the natural environment. Thirdly, internalization of eternality is asked to correct the market failure. This requires the public policy such as imposing a talsubsidy, assigning a property right or implement a more detailed environmental quality standard through, because use of the natural resources can be. allocated optimally by the intervention of government or social associations.

문화산업은 인간의 창작성을 활용하여 고부가가치를 창출할 수 있다는 점에서 매우 중요한 분야로 인식되어 왔다. 그럼에도 불구하고 지금까지 문화산업에서는 기업가의 역할보다는 개인 창작자의 영감과 아이디어 등에 주로 초점을 맞추어 왔다. 하지만 최근 "한류(韓流)" 등의 영향으로 인해 문화산업에서 기업가의 역할이 중요해지고 있다. 이에 본 연구에서는 리더의 혁신지향성, 위험감수성, 선발자우위, 종업원에 대한 보상, 재도전용이성이 마켓리더십에 미치는 영향에 대해 분석하였다. 그 결과, 위험감수성, 선발자우위, 종업원에 대한 보상, 재도전용이성의 경우에는 모두 마켓리더십에 긍정적인 영향을 미치고 있었으나, 리더의 혁신 지향성에서는 유의미한 결과가 도출되지 못하였다. 이는 문화산업에서 마켓리더십을 가지기 위해서는 리더의 직관보다 구성원들의 창의성이 발휘될 수 있는 환경 조성이 더 효과적임을 보여준다. 본 연구의 결과는 문화산업에 속하는 기업들이 전략을 수립하거나 정부에서 정책을 결정할 때, 기업가정신이 강조되어야 함을 시사한다.

During the past 100 years, Korean fisheries management policies have enforced the license system, it is the most typical regulation system in Korean fisheries. Even now, it has caused resource management failure, it has also invited economic inefficiency and inequity. Accordingly, the Korean government has recently introduced the self-regulatory management system for fishermen with the TAC system. These systems are one of the most market-oriented regulation systems in fisheries management systems. It is defined as regulatory policy tools other than regulations with command and control approach. It is also called “alternatives” which is composed of regulatory alternatives and non-regulatory alternatives. The self-regulatory management system and the ITQ system are cooperative-based co-management between government and fishermen as an alternative management strategy ; it is gaining the increasing attention to improve the effectiveness of fisheries management in Korea. It is expected not only to positively improve function in fisheries regulation, but also to decrease inefficiency in fisheries policies. However, these systems have many problems. The monopolization of rent is one of the typical examples. As solutions for the problem in the aspect of fishery management, fisheries policy is need of approach to industrial organization. For instance, Contestable market theory is one of the good theoretical background, it mean that market is able to free entry and free exit. Thus, fisheries management carry out policies such as revitalization of the used market of capital goods in fisheries, organize of the self-regulatory management group. Conclusively, as the exploiters and managers, fishers and the government should put emphasis on improving economic efficiency so that fishery would grow as an industry that contributes to the increase of social welfare, and the change to that direction will be the only way for our fisheries to preserve its importance.

By explaining the essence of corporate governance as well as disclosure and transparency, the study examined the guarantees of applying disclosure and transparency to firms listed on the Saudi stock exchange. The research also addressed the disclosure and transparency duties of firms listed on the Saudi stock exchange. Finance to prepare a prospectus, as the Capital Market Authority's regulations required that the prospectus includes information that enables the investor in securities to make his investment decision based on real foundations based on the issuing company's financial position and to ensure that companies fulfill that disclosure in the prospectus. Firms who fail to disclose are required by law to do so, and the Capital Market Authority's laws mandate companies listed on the financial market to regularly report fundamental events linked to the issuer or the securities issued by it. The Capital Market Authority must make it available to the public dealing with the business issuing the securities, and The Capital Market Authority's Law and Regulations have imposed fines on corporations that do not comply with disclosure and make the Board of Director's report available. The research focused on activities that the legislator deemed to be a breach of the obligation of openness, such as the danger of many measures aimed at ensuring the impartiality and transparency of trading in the Saudi financial market, as well as the absence of conflicts of interest. The research also addressed the sanctions imposed on The source for failing to meet the obligation of disclosure and openness, as well as the mechanisms of compensating persons harmed by the failure to meet that responsibility.
