This study examined the impact of team characteristics(introduction of the team approach team empowerment, leadership of team leaders, open communication director's commitment) on team effectiveness (adaptability to the environments, job satisfaction the positive team culture, cost efficiency) in university libraries. The study used a survey design with a questionnaire to staffs who worked at f academic libraries in South Korea. The major findings from the empirical analysis are as follows. The well-prepared introduction of team approach and director's strong commitment were positively related to the team effectiveness variables such as adaptability to environment, job satisfaction, and cost efficiency.

In this study, discharged nylon fibers were added to asphalt concretes to be compared with fatigue life and analyzed in economic point of view. A four point bending fatigue test was conducted, and as a result, nylon fiber reinforced asphalt concretes that showed a 10percent increase in fatigue life compared to ordinary asphalt concrete. The economic analysis confirmed that the maintenance cost was decreased by 540 million won throughout the analyzing period. It is thought discharged nylon fiber reinforced asphalt will cause more economic and social effects than was shown by life cycle cost analysis.

Environmental impact is getting more attention in many feasibility studies for railroad-related projects and research items. For sustainable growth and green transportation, the benefits typically used for feasibility studies in railway-related projects, are composed mostly of economic criterions which is not considering growing attention on changing paradigm. Based on the analysis of current methodologies, improvements in estimating environmental impact especially on noise and pollution are suggested. Active steering bogie has been proposed to satisfy stabilizing and steering performance of railroad. This paper describes the feasibility study of the active steering bogie for a urban railway vehicle based on environment-related criteria.

'Low Carbon, Green Growth' may be the achievable target in industry section, depending on whether less reliance on fossil-fuels use can bring higher productivity growth in the long run. This paper tests for the short-run and long-run effects of investment on energy-saving equipments on productivity growth in the Korean manufacturing industries. The investment in energy efficiency causes an increase in costs (measurement effect) in the short-run, but in the long-run likely improve energy intensity and reduce costs (positive real effect) despite the delay in new other investment for technical innovation (negative real effect). A 2SLS regression was attempted to deal with endogeneity of energy-saving investment. The productivity effects were tested for five manufacturing sub-industries showing relatively high energy intensity with annual time series data from 1982 through 2006. No productivity effects were accepted for all five sub-industries except Chemical products. Positive real effect was considered to be exceeded by negative real effect, resulting in decreased productivity growth for Chemical products.

A coastal marine ranching project in Uleungdo had been conducted for 5 years from 2013 to 2017 with investment costs of 5 billion won, for the special purpose of the deployment of artificial reefs, the release of young fishes. The paper focuses on an ex-post analysis of the economic feasibility for the project after completing the project, which is apart from a preliminary viability. For economic analysis, the economic benefits are derived from direct benefits including increasing effects of fisheries income and saving effects of harvesting costs, and indirect benefits including increasing effects of recreational fishing and preservation effects of coastal marine ecosystems while economic costs include releasing and purchasing costs of artificial reef and juvenile fish, R&D costs, maintenance costs and harvesting costs. The result shows that the project should not be accepted according to NPV=-0.125 billion won, IRR=4.5% and B/C ratio=0.98 under Scenario 1 which considers direct benefits and indirect benefits excluding the preservation values, while the project should be accepted under Scenario 2 indicating NPV=30.9 billion won, IRR=11.3% and B/C ratio=1.49 which considers the direct benefits as well as the indirect ones including the preservation values, based on 4.5% of the social rate of discount.

In this paper, we build server consolidate virtualization focusing on NT server dilapidated and through analysis of the effect of this, has been presented the following results. First, it was possible to obtain an increase in the constant temperature constant humidity chamber efficiency by securing the upper surface space for computing data center mounted virtualization integration server servers multiple physical. Second, by the deployment of virtualization of a large server dilapidated, the introduction of new resources and the cost of maintaining computerized data center and reduce power consumption, the reduction of hardware introduction of additional due to the new server deployment it was possible to derive a cost reduction effect. We obtain the reduction of 89% and 79% compared with conventional consumption of cooling and power savings of the top surface, respectively. Integration of NT servers are virtualized can be expected to change in the Green-IT to contribute to providing the maintenance costs of computing centers in the future as well as current. Building a virtualization server integration applied in this paper can be similarly applied to the UNIX system and to integrate the server group other.

조달청은 지난 8월 24일 이에스콘트롤스(주)의 "자동제어시스템(ES-2000)"등 43개의 제품을'우수조달물품'으로 선정했다. 이번에 지정된 우수조달물품은 변리사 대학교수 등 외부 전문가의 기술심사를 통해 지식경제부장관 등이 인증한 신기술제품 4개와 특허제품 39개 품목이다. 이에스콘트롤스가 개발한 ES-2000은 그동안 해외제품에 의지하던 것에서 벗어나 수입대체효과를 거둬 평균에너지의 45% 절감 및 비용절감에도 기여할 것으로 기대된다.

6시그마''를 도입, 추진해온 LG전자 정보통신 구미사업장은 에너지절감활동 역시 ''6시그마 Tool''에 따라 진행된다. 6시그마는 생산활동에 있어서 1백만개의 제품이나 서비스 가운데 단 3.4개의 불량만을 허용하는 전사적 경영혁신 활동이다. 현재 품질경영 운동의 주류인 ''1백PPM(parts per million)''이 1백만개중 1백개의 불량을 허용하고 있으니 얼마나 높은 수준인지 알 수 있다. ''완벽 경영''에 도전하는 경영혁신활동인 셈이다. 이곳에서 지난 5월부터 약 4개월에 걸쳐 실시한 ESCO 조명교체사업은 에너지절감과 동시에 개체비용에 따른 경제적인 부담을 덜어줌으로써 매우 효과적인 6시그마 활동으로 주목받고 있다.

6시그마는 기업의 경영성과를 극대화를 위해 개발된 경영전략 방법론으로 알려져 있다. 기업이 경영성과의 극대화를 위해서 추구하는 것은 "이윤 추구"가 목표이다. 그래서 기업은 시장 점유율 확대를 위해 매출향상과 이익확대 및 원가절감을 위해 지속적으로 경영혁신활동을 추진하고 있다. 6시그마를 추진하는데 있어서 3P(Project, People, Process)가 6시그마 성공에 있어서 가장 핵심적인 요소다. 이는 능력 있는 조직구성원으로 하여금 문제해결을 통해 기업이 달성하고자 하는 목표를 달성하기 위해 프로젝트를 수행한다. 하지만 모든 프로젝트의 효과가 원가절감 또는 이윤 추구에 영향을 주는 것은 아니다. 경영성과를 극대화하기 위한 프로젝트는 재무성과 중심의 과제가 선정이 되어야 하고 그 재무성과는 품질비용(COPQ) 분석을 통해 도출될 수 있다. 본 연구는 K사에서 수행했던 프로젝트의 재무성과를 분석하여 품질비용(COPQ)이 프로젝트 효과에 미치는 영향을 조사고 향후 수행되는 프로젝트의 재무성과를 극대화하기 위한 프로젝트 선정의 효과적인 방향을 제시하고자 한다.

The expense Our country's land logistics system is becoming backlog day by day. The greenhouse gas which it discharges specially from the vehicle causes a ecocide and traffic expense to make. The traffic energy curtailment which the government enforces during that time and environment-friendly green goods policy lost the effect. Therefore, This research propose the car-ferri network which is the most effective logistics system substitutes the land logistics system. This research will contribute improving the north and south logistics network of Pusan and Seoul region and will be able to reduce a various goods expense.
