This paper is an exploratory study to investigate the influence of characteristics of local government web-sites on user satisfaction and trust. The objective of this research is to identify the characteristics of local government web-sites influencing on user satisfaction and trust, and determine how they affect user satisfaction and trust. From the literature review, we identify four characteristics which are expected to influence on user satisfaction: technical, information, customer-oriented, and work-performing characteristics. In addition, we develop research model that the four characteristics are expected to affect user satisfaction and trust via users' perceived values. The results of the research are as follows. The technical, customer-oriented, and work-performing characteristics significantly affects perceived values, which significantly affected user satisfaction and trust. Perceived value is partially mediated by user satisfaction in affecting user trust. The characteristics of local government web-sites affecting perceived values differed partially by the purpose of visitor. As for the personal goal, the technical, customer-oriented, and work-performing characteristics significantly affect perceived values, with the technical and customer-oriented characteristics having more significant effects. As for the business goal, the technical, information, work-performing characteristics significantly affected perceived values, with information characteristics having more significant effects.

The International Atomic Energy Agency (IAEA) entails independent decision-making for the safety supervision of civil nuclear facilities. To evaluate and review the safety of nuclear facilities, the national regulatory body usually consults independent institutions or external committees. Technical Support Organizations (TSOs) include national laboratories, research institutions, and consulting organizations. Support from professional organizations in other countries may also be required occasionally. Most of the world's major nuclear power countries adopt an independent nuclear safety supervision model. Accordingly, China has continuously improved upon the construction of such a system by establishing the National Nuclear Safety Administration (NNSA) as the decision-making department for nuclear and radiation safety supervision, six regional safety supervision stations, the Nuclear and Radiation Safety Center (NSC), a nuclear safety expert committee, and the National Nuclear and Radiation Safety Supervision Technology R&D Base, which serves as the test, verification, and R&D platform for providing consultation and technical support. An R&D system, however, remains to be formed. Future endeavors must focus on improving the technical support capacity of these systems. As an enhancement from institutional independence to capability independence is necessary for ensuring the independence of China's nuclear safety regulatory institution, its regulatory capacity must be improved in the future.

The development of accelerator science and technology has been accommodating ever increasing demand from scientific community of the beam energy and intensity of proton beams. The use of high-powered proton beams has extended from the traditional application of nuclear and high-energy physics to other applications, including spallation neutron source replacing nuclear reactor, nuclear actinide transmutation, energy amplification reactors. This article attempts to review development of proton accelerator, both linear and circular, and issues related to the proton beam energy, intensity as well as its output power. For related accelerator physics and technical review, one should refer to the recent article in the Reviews of Modem Physics [1]

This study presents the review of technical requirements of safety and security for the developed high-speed freight train which will be serviced on the existing route of the high-speed line. There is no any experience to make a system design of high-speed freight train in Korea until now. We need to make a new regulations of commercial service.

본 연구의 목적은 투입물 효율함수를 이용하여 한국농가의 소득계층을 대상으로 기술효율, 환경효율, 규모효율을 측정하고, Tobit 모형으로 그 결정요인을 분석하는 것이다. 본 연구는 비모수적(nonparametric) 방법에 의존하여 재화의 가격이나 최적화 행동에 관한 가정없이 투입요소와 산출량에 의존하여 기술효율을 계측한다. 생산기술은 바람직한 재화와 바람직하지 못한 오염물의 결합생산을 모형화한다. 규모불변과 강처분 하에서 평균 기술효율 수준은 0.437 이었다. 기술비효율의 원인은 순수기술비효율이 47.7%, 규모비효율은 11.3%, 환경비효율 3.2%의 순이다. 규모체증 상태에서 생산농가는 전체농가의 70%를 점유하고 규모체감 상태에서 생산농기는 전체농가의 27%에 이른다. 효율성을 결정하는 요인으로 소득계층이 높을수록 중장기 부채가 높을수록 단위면적당 질소배출량이 높을수록 기술효율은 높았고, 경지면적당 농업경영비가 높을수록 기술효율은 저하되었다. 환경효율에서는 BOD 배출량, 단위면적당 기계도입, 자본의 생산성 유의적이고 음(-)으로 나타나, 청정기술이 아닌 단순한 기계화의 확대는 환경효율을 악화시키는데 영향을 주고 있음을 시사한다.

본 연구는 NCS 기반으로 개편된 미용사(피부) 검정형 자격과 과정평가형의 자격시험에 관한 선행연구의 체계적 문헌 고찰을 통해 국가기술자격 미용사(피부) 종목 과제 및 평가방법에 대해 비교·분석 하였다. 검정형 자격은 암기 위주의 이론시험과 단순 기능 반복을 통한 작업능력을 기반으로 평가가 이루어져 자격과 일이 상호 연계되지 않고 있고, 과정평가형 자격은 상대적으로 시험 집행을 시작한 기간이 짧은 상태로 시행기관에서의 자체 내부평가의 신뢰성 저하 문제가 지속적으로 나타나고 있다. 향후 현재 평가에 반영되고 있지 못하는 다양한 능력 단위를 적용하여 실기시험 평가 항목에 포함할 수 있는 상위자격의 신설 및 실기시험 평가방법 개선 등을 통해 현장과의 연계성을 제고시키고 관련 분야의 현장 적응 및 재교육 시간 단축 등의 자격제도 혁신이 필요한 것으로 사료된다.

On the job training is useful : a part of on the job training has increased the marginal productivity of future and rate of wage. Investment in a human capital depends on character of investment and market conditions. The innovation role of small and medium firms has recently received increasing attention in newly industrializing countries as they attempt to transform their industries from labor intensive to technology intensive. It also suggests some implications to the small and medium firms' strategies and public policies accelerating research and development. Lack of qualified scientists and engineers often inhibits the small and medium firms' ability to access and assimilate external technical information. Such technical personnel are particularly scarce in NICs. Therefore, how to employ these technical staff should be an important issue for small and medium firms seeking to acquire distinctive competences. Small and medium firms must invest further education and training to its labor.

Technology measurement is related with how to construct indicators of technological change and relative ranking of technological sophistication. Many attempts have been made to understand the measurement of technology. However, technology measurement still remains little understood problem in spite of its importance. This article is concerned with improving the measurement of technology by introducing market factors into the model. It illustrate a simple approach to the measurement of technology. This approach is based on the characteristic-space paradigm of technology. A relative ranking of technological sophistication for a product is measurable as a set of characteristics. The main feature of the proposed approach is the combination of technical factors and market factors. Technical factors are reflected in the definition of technological sophistication. Market factors are embraced in the determination of the relative importance assigned to each technology defining characteristics. Thus, the weight is determined by technical factors and market factors, which differentiates the study from the past based on judgmental technique such as experts' opinion.

This paper provides an overview of the use of different Distributed Optical Fiber Sensor systems (DOFSs) to perform Structural Health Monitoring (SHM) in the specific case of civil engineering structures. Nowadays, there are several methods available for extracting distributed measurements from optical fiber, and their use have to be according with the aims of the SHM performance. The continuous-in-space data is the common advantage of the different DOFSs over other conventional health monitoring systems and, depending on the particular characteristics of each DOFS, a global and/or local health structural evaluation is possible with different accuracy. Firstly, the fundamentals of different DOFSs and their principal advantages and disadvantages are presented. Then, laboratory and field tests using different DOFSs systems to measure strain in structural elements and civil structures are presented and discussed. Finally, based on the current applications, conclusions and future trends of DOFSs in SHM in civil structures are proposed.
