This paper strives to examine the acquisition process in public libraries. It specifically attempts to survey the budget allocation, duties and organizational structures of acquisition departments in public libraries, and the overall process of book selection and acquisition. Data was drawn from a survey of 545 public libraries in the country. Specific statistics were gathered through literature and interviews to be analyzed, even though they were not very detailed in nature. In looking at the actual acquisition process, a thorough comparison on the backgrounds, outlines and characteristics of current projects and an analysis on the specifics of each project was also conducted.

미 법무부의 독점금지국(the Antitrust of the U.S. Department of Justice)은, 지난달 제일제당과 두 일본기업이 미 독점금지법 위반을 인정하는데 동의했다고 발표하였다. 미 법무부 독점금지국은 미국 상거래에 영향을 주는 호전적 카르텔에 있어서는, 연루된 기업의 국적에 상관없이, 또한 그 기업이 미국 역내에 있느냐 역외에 있느냐를 불문하고 자국의 독점금지법을 일괄적으로 적용해 오고 있다. 따라서 이런 기업들은 미국 독점금지법하에서 벌금이나 심지어는 금고형으로부터 자유로울 수가 없는 것이 현실이다. 미 법무부의 독점금지국은 판사의 형 선고 재량권을 현저하게 약화시킨 형 선고에 관한 지침(United States Sentencing Guidelines), 그리고 카르텔 공동협력에 있어 공모에 대한 증거제공 및 공동행위를 신고한 기업에 대해 형량감경제도(Corporate Leniency policy)를 효율적으로 운영함으로써 지난 몇 년간 미국 역외에서 발생한 공동행위에 대해 수많은 형사적 유죄판결을 받아내었다. 지난 수십년간 독점금지국은 가격고정, 입찰담합, 시장할당 그리고 셔먼법에 의해 당연위법으로 인정되는 경쟁자간의 합의에 관련된 기업들과 개인들에 대해 조사하고 형사적으로 소추해왔다. 이 모두는 불합리하게 거래를 제한하는 합의로 독점금지법에 의해 금지되는 행위들이다. 연방법은 현재 셔먼법 위반에 대한 벌칙으로 거래를 제한하는 공모에 합의함으로써 셔먼법을 위반한 기업에게는 최고 1,000만 달러, 개인에게는 최고 35만 달러의 벌금을 부과할 수 있으며 최장 3년간의 징역에 처해 질 수 있다고 규정하고 있다. 그러나 벌금액은 1987년의 형사벌금개선법(The Criminal Fines Improvements Act: 법원이 개인 및 기업에 대한 범죄에 의해 야기된 이익이나 손실의 두 배에 해당하는 금액 중 더 큰 금액을 선택적으로 부과할 수 있다는 규정)에 의해 극적으로 늘어나고 있다. 이 논고에서는 미 법무부 독점금지국이 글로벌 카르텔과의 전쟁을 성공적으로 수행하게 된 과정을 간략하게 검토하고, 그 과정에서 다루어진 중요한 사건 중 두 사례를 선정해서 고찰해 보기로 하겠다.

This research aims to provide a solution for the improvement of private security according to the change in criminal environment. The main cause of crime can be found in the anti-functional dimensions including value set disorder, social phenomenon variation, information-based, globalization and urbanization. In this environment, the private security sector has dramatically increased in a quantitative viewpoint, but it is insufficient in a qualitative viewpoint. This paper recognized this problem and demonstrates a solution for improvement through classifying elements of private security into relevant legislation, education institutions, security companies and security associations. The analysis result is a follows: First, motivation and satisfaction rate of escort and security related major has shown to be high. However, respondents evaluated the guard educational institution negatively. Second, the motivation of entering into the private security sector for internal staffs has shown to be positive and sound. However, the job satisfaction rate has shown to be low due to excessive competition, negative perception of occupation and low earning. Third, respondents gave an average mark to the Security Association's management and operation. In addition, the mutual-aid project received the same mark. Negative feedbacks were given to the protection of member's interest and to association operation and policy, while positive feedbacks were given to the degree of member's cooperation towards association policies.

Construction companies have been interested in the construction duration which importantly affects the performance and the success of the construction projects in accordance with the systemic changes such as five days per week system, introduction of construction duration reduction bidding system and post sale system nowadays. It is also very important to estimate and forecast properly the construction duration as the construction companies compete for the projects in the situation of construction market reduction and the lowest bidding system. Recognizing the importance about the construction duration, the researches about comparing and analyzing or estiamting the construction duration have been performed. However, comparing studies about the construction duraion have been limited to the apartment and office building in domestic area. Many studies about forecasting construction duration have been performed through stochastic analysis and simulations. Little research has been addressed the comparison analysis of the real construction duration about the mix-use building and officetel building which occured according to the changes of the building requirements. Therefore, the objective of this study is to compare and analyze the real construction duration and the hypothetical construction duration about the mix-use building and officetel building of the domestic companies. Moreover, we select the most competitve construction company to get the strengths and analyze the competitive advatages of the construction companies about construction duration.

Korean engineering firms need to improve their performance in order to stay competitive in the globalize environments which has been led by some international movements including World Trade Organization (WTO) and Free Trade Agreements (FTA). There have been various activities and researches focusing on how to improve competitiveness of Korean engineering firms and the out-of-fashion Engineering Project Delivery System (EPDS) has repetitively identified as one of main barriers to deter advancements of Korean engineering industry. Therefore, this research attempted to investigate global standards of EPDS such as International Federation of Consulting Engineers (FIDIC), American Federal Acquisition Regulations (FAR), Brooks Act, and so on. The procedures of international EPDSs along with a few case studies were comprehensively analyzed and compared with Korean EPDS in order to propose recommendations of improving Korean EPDS. Some major differences between international and Korean EPDS were identified and they includes emphasis on qualifications of engineers and/or firms rather than their proposed cost, extensive use of long and short-list, common use of negotiation process, etc. Research findings are envisioned to guide the Korean public engineering sector to innovate Korean EPDS.

Despite the government's constant exertions on making a win-win environment through positive discrimination for small and medium-sized companies and local companies, they are suffering from order polarization, weak competitiveness to win a project, and low profitability in highly competitive market situations resulting from the contraction of the construction market. This study examined the U.S. policy and regulations on protecting the relatively weak entities in the construction industry, focused on a goaling program, setting aside the bid preference for small and middle-sized companies and local companies. From benchmarking, some implications were drawn to reconsider the goal of policy and regulations for small and medium-sized companies and local companies. In conclusion, unlike domestic positive discrimination regulations, which are based on the concept of market sharing that can allow a paper company to survive, those of the U.S. are based on the principle of fair competitiveness, and also provide a certain degree of advantage for small and medium-sized companies and local companies. Therefore, the domestic positive discrimination policy and regulations for small and medium-sized companies and local companies need to be reconsidered toward the direction of not only protecting them but also to strengthen their competitiveness in the market.

Using bidding data collected from the World Bank's open database, this research performed a series of competitive analyses of the major countries that have participated in the Bank's engineering consulting services contracts in Vietnam. The goal of the analysis was to evaluate the performance of Korean engineering firms to date, and provide strategic recommendations for future projects. Results showed that Korean firms had a high bid acceptance rate, comparable to major developed countries. The success was attributed to the high technical scores in the selection process. Comparatively, financial scores were not competitive and inferior to developing countries such as China and India. Results of a 'Skitmore' analysis revealed that Korea was competitive in medium size projects and were situated between developed and developing countries. Korea thus needs to increase participation in basic and detailed design services, 2) improve labor costs through 'localization' and latest technologies, and 3) and venture into larger sized projects.

This paper proposes a Cournot model that can be used to analyze the strategic behaviors of generation companies which try to maximize their profits in an imperfectly competitive electricity and carbon markets. The proposed model consists of two parts. First, the strategic behaviors of generation companies are modeled based on the Cournot theory. Second, the market operation is modeled based on the assumption that the market operator tries to maximize the total social welfare in consideration of environmental welfare. To find the Nash equilibrium of the proposed model, the two-level optimization technique is used. The proposed method has been applied to an illustrative example of oligopolistic markets. We found that the proposed method has strong potential to analyze the influence of the strategic biddings of the generation companies and the impact of renewable generator on markets where the competitiveness of the markets is not fully developed.
