We have developed a position-sensitive proton recoil telescope (PSPRT) which employs a position-sensitive photomultiplier (PS-PMT) and a scintillator for both a radiator and a proton-detector. This system is expected to achieve high energy resolution under a large solid angle, because it enables to obtain the information not only on the proton energy but also the recoil angle from the position data for both detectors. The response of the PSPRT for 14.1 MeV mono-energetic neutrons was measured, and the PSPRT proved to be operating as expected.

Seoul Metro is celebrating 32 anniversary this year and through developments over the years it is being evaluated as the 3rd in the world in operational sizes, the 4th in the world in facility sizes, it transports about 4 million passengers per day and it is now a vital public transportation means. However, the track maintenance organization and manpower structures along with technology cooperative office were led by unions that do not like changes and overshadows the trends of changes by expanding organizations and recruiting personnels and it is going against the current of times. Thus, it is time when a break point is required for breaking away from labor-intensive methods of the past that rely on hand works and vertical organizational structures. Therefore, this study investigates the states of national.international track maintenance operations and examines and analyzes the problems so that it can be utilized as base data for efficiently operating the organizations and maintenance works on track fields.

According to the dynamic changes in the business environment, the structural transformation of firms has had an observable trend. An increasingly large number of firms have been transforming into either project-based organizations or project expert groups. This study aims to investigate the antecedents required for the optimal level of empowerment with consideration of the project-based team environmental nature and job characteristic. Three factors are applied to measure the significant effects on psychological empowerment as the result variables. To determine the antecedents and consequent factors of psychological empowerment, employees' interviews and precedent studies are used. For the empirical study, four determinants of empowerment variables are modeled into a second-order reflective construct. This study finds that psychological empowerment significantly affects performance. Therefore, this study can serve as a guideline for development and operating methods for project success.

The aim of this study is actual conditions to analyse of community center in Cheongweon-gun and propose operation method. In this study, I deduced some problems and proposed improvement planing corresponded to new needs through such as external appearance, inner space analysis, operating actual conditions analysis and etc., of existing community center in Cheongweon-gun. And I wish to present more efficient architectural space organization and operation method with these surveying results. The result of this study are as follows; Community center as representative community facilities is necessary to reflect of village characteristics on the exterior of buildings, and decision of scale and usage considered number of residents, visitors, and ages. For management of the community center, it is necessary of sustainable obtain of management cost, and provision against rebuilding and enlargement of building.

Organizations worldwide have implemented quality management system, ISO 9001:2000 and environmental management system, ISO 14001:2004. Researches have been conducted regarding occupational health and safety management system, integration of these management systems, and extension to corporate social responsibility and sustain ability management system, ISO 26000. This paper examines quality and environment management systems for machinery and metal companies using audit results. We perform statistical tests to see if there are any significant differences of minor nonconformities for requirements of ISO 9001:2000 and ISO 14001:2004 based on implementation motive, operating periods, and organization's size. We also present causes and reasons for statistical differences and minor nonconformities to use as references for implementing efficiently quality management system and environment management system.

Many organizations are operating knowledge management(KM) for their competitive advantage in dynamically changeable markets. To support KM successfully, they are considerably investing in knowledge management systems(KMS) development. By using KMS, organizations can lead to the improvement of their employees' knowledge level and the removal of inefficient tasks, consequently resulting in their competitive edge. On the basis of the power process perspective, this study investigates the CEO leadership and its organization's performance for successful development of KMS.

Since the accuracy of precipitable/integrated water vapor estimates from GNSS measurements is proportional to the accuracy of water vapor Weighted Mean Temperature Model (WMTM), the WMTM is a significant formulation in the retrieval of precipitable water vapor from zenith wet delay of GNSS signal. The purpose of this paper is to develop available the WMTM to apply for GNSS meteorology in the region of Algeria, by using the Algerian radiosonde network in the World Meteorological Organization (WMO). It can be concluded that the available GNSS precipitable water vapor which is retrieved by the developed Algerian Weighted Mean Temperature Equation (AWMTE) can be useful technique for sensing of water vapor in the Algeria, after Algerian Continuously Operating Reference System (CORS) will be constructed.

This paper defines the Safety Management System(SMS) based on the rail safety act and surveys the status of the English rail SMS and International Civil Aviation Organization (ICAO) SMS and OHSAS18001 SMS. Through the investigation of establishment and implementation status of domestic rail operators' SMS, the improvement directions of the current rail SMS are developed. First, to establish the continual improvement system for SMS, the guide which describe detailed continual improvement method for each steps of SMS including management review by CEO shall be established and implemented. Second, to settle the SMS based on the risk management, it is necessary to endeavor for converting the rail operators mind and to establish the supply system of operating model and basic data and to define the requirement precisely and to include in the related guide for the risk management.

The problems and the limits of outsourcing strategies are disclosure of the knowhow to someone and rapid confrontation of difficulties by a outsourcing-supply company, limitations of quality control and hold-up of quality. From the result of this study, we found that development of outsourcing strategies will be not vertical relationship between a outsourcing-supply company and a outsourcing-demand company but horizontal relationship (co-sourcing) between those supply and demand company. Especially, core-affairs, control of operating costs and costs reduction must have the precise purpose and carry out capacity and affairs of organization.

This study focuses on the case of FIRA(Korea Fisheries Resources Agency) and analysis the introduction effect of BSC(Balanced Score card) implementation. So it will set forth the improvement method and the implications for Quasi-governmental organizations which are trying to introduce or are operating the BSC system. This study suggests how to improve the problems of BSC as below : (1) Building of reasonable and balanced evaluation index system (2) Acquiring of comparability and equality through adjustments of group evaluated (3) Enhancing of competence and professionalism of evaluating group (4) Alleviating of difference gap of performance incentives and promoting of non-money incentives (5) Enhancing of positive acceptance and recognition for BSC.
