In the delivery systems for public construction works, design-build methods such as turn-key and alternative have contributed to improving the quality of structures and developing the construction technology. However, it is pointed out that construction based on a design-build method is likely to waste a budget due to its higher contract price than construction based on a design-bid-build method. Other issues such as contract monopoly, bid rigging and deliberation irregularity in design-build. Since there are not much works have been accomplished to comparatively analyze the actual performance and effect based on delivery methods, discussing and judging the performance and effect of each deliver method with limited information could lead to an error. Thus, this study by extensively investigates the actual project cost data, ranging from contract price to the construction cost of the public construction works and comparatively analyzed the characteristics of each delivery method about cost structure and fluctuation trend. This work is expected to assist stake-holders in properly understanding delivery systems for public construction works and promoting their efficient management.

As the social responsibility of corporations becomes more important, recently, many corporations have made constant efforts to preserve natural environment. Environmental investments had been traditionally thought as cost factors and sources of negative effects on a firm's financial performances. In this study, we explore the relation of financial and environmental performances of Korean corporations. We use default probability as well as ROE as indicators of financial performances. We find that there is positive correlation between ROE and environmental performance, and negative correlation between default probability and environmental performance. This implies that Korean corporations should recognize environmental investment as means of improving corporate value.

The purpose of this study is to estimate the effectiveness of vocational training for the unemployed. The results show that the unemployed who received vocational training commended better performances than those unemployed without any vocational training in respect to the duration of job-seeking period and the success rate of obtaining a job, however no significant change can be found in their wage level after holding a job between the two groups. It can be seen from the cost-benefit analysis, although the trained unemployed show better performance than the untrained unemployed, those that were trained by the Korea Chamber of Commerce and Industry(KCCI) do not show better performance than those that were trained through a private vocational train school since the training cost is much higher in the KCCI.

Securing publicness and efficiencies are the two core goals for implementing quasi-public bus system. However, researches for evaluating the quasi-public bus system with respect to the two goals have been very limited. This study represents an attempt to evaluate the system performance in these two aspects. To achieve this, a framework for performance evaluation is developed. Utilizing the framework, the 5-year performances of the quasi-public bus system in Busan are evaluated. Acess, agency and public interests are employed as criteria for publicness evaluation. Financial aspects of operators, labor, vehicle utilization, productivity and operational costs are selected as indicators for efficiency evaluation. The results show that the publicness of bus services has been vastly improved, while the efficiency has been also improved in most areas except in cost and vehicle utilization aspects. The results of this study will be of use for planners and policy-makers developing strategies for system improvement. It is hoped that this study can be further refined by adding and adjusting indicators which this study may neglect or ignore.

Quality system of construction industry in Korea was a means to prevent unqualified construction work. But lately, it has became an essential requirement. So, lots of construction companies acquire ISO quality management system which provides fundamental management criteria. Now, most of the Korean construction companies have got IS0 quality management system. So, getting ISO quality management system doesn't mean advantage in public competition of construction bidding and that causes increase in the maintenance cost. That's why some construction companies abandon the 150 certificate. Therefore, the authors need to check the effect of ISO quality management system. For this, the authors provide the performance measurement index of ISO quality management system.

지난 2008년 12월말 정보보호 시스템에 대한 보안성 평가의 소요시간과 비용을 절감하기 위한 정책이 등장하면서 이에 대한 기사들이 등장했다. 보안성 평가과정에 있어 비용과 시간 절감은 정보보호 업계로서는 반가울 수밖에 없는 일. 그렇다면 실제 그 과정과 성과는 어떠했을까.

기업활동으로 인해 수반되는 산업재해를 완전히 제거할 수는 없다하더라도 사고의 발생빈도를 저감시킬 수 있다. 즉, 해당 기업이 안전관리에 얼마만큼 투자를 하느냐에 따라 산업재해예방에 괄목할 만한 성과를 이루어낼 수 있다. 안전경영의 성과는 단지 기업윤리차원의 문제뿐만 아니라 비즈니스의 성공을 보장하는 것으로 기업의 가치창조에 역점을 두어야 할 것이다. 생산성과 높은 안전경영 성과간의 상관관계는 매우 포지티브(positive)한 것임은 여러 사례에서 이미 증명되어졌다. 따라서 안전경영은 품질확보, 이윤창출과 비용절감, 비즈니스기회의 선점에 필수적임을 인식해야 한다.

This study examines whether there is agency cost in a public R&D subsidy program by applying agency theory. If there is agency cost, the composition ratio of the government subsidy and the firm's own R&D fund would have a significant (-) effect on technological performance. Companies that received a public R&D subsidy in Korea from 2000 to 2009 were selected as a sample. Frequency analysis and multiple regression analysis were used. The independent variables was the ratio of public R&D subsidy cost to the Firm's own R&D cost, and the dependent variables were the number of patent applications and the number of patents registered. The control variables were firm size and R&D cost. The results show that there are agency problems in the government-sponsored R&D system. A future study is needed to examine how much agency problems deteriorate the efficiency of the system.

It is common that the analysis of VE/LCC is performed in design phase of quay wall structures. The analysis is mainly executed based on experience and engineering sense of expert considering the selection of construction method, construction and maintenance cost. Recently there are increasing demands on the analysis that includes uncertainty and vulnerability of input parameters, for this purpose, fuzzy reliability based probabilistic VE/LCC analysis model for quay wall structures is suggested. In VE/LCC analysis for quay wall structures, the application of probabilistic analysis method give very similar results compare with those of deterministic analysis method. It is anticipated that the methodology proposed in this paper can also be utilized in the design and maintenance phase of other facilities where decision making is made for the probabilistic life cycle cost and value analysis.
