PLS(Pohang Light Source) is 2.5 Gev synchrotron radiation source in Pohang, Korea, which is under operation since 1995. The hardware and software of the old BPM(Beam Position Monitor) data acquisition system for the PLS storage ring was completely upgraded to increase its performance and stability. The new BPM data acquisition system is based on VME-based EPICS (Experimental Physics and Instrument Control System) IOC system. We used 16-bit resolution analog-to-digital conversion board to digitize analog BPM signals. We developed a data average software to average raw BPM data using reflective memory board. We also developed device drivers for VME I/O boards used, IOC database for PV's(Process Variables). The new BPM data acquisition system is currently running for routine operation with good performance and stability. In this paper, we present the hardware and software of the new BPM data acquisition system DTL water skid cooling system and Resonant Control Cooling.

International Olympic Committee (IOC) prohibits the use of cyclofenil for male. To prove whether cyclofenil product was taken or not, the analytical method in urine using GC/MS was established. The extraction recoveries of cyclofenil and its metabolites were higher in the range of pH 5-9. Because the parent drug (cyclofenil) was not excreted in urine, metabolites were detected and theses were used as a criteria of cyclofenil dose. Therefore the metabolites were hydrolyzed, extracted at pH 9.6, derivatized with MSTFA and analyzed by GC/MS.

International Olympic Committee (IOC) prohibits the use of carteolol which is one of ${\beta}$-blockers. To prove whether carteolol product was taken or not, the analytical method in urine using GC/MS was established, and metabolism and excretion study were evaluated. As compared with acid hydrolysis, enzyme hydrolysis method was more efficiency. Coefficients of variation for intra-assay precision was around 10%. Error was less than 5% except the concentration of $0.05{\mu}g/m{\ell}$. Recovery was 78.5% at $2{\mu}g/m{\ell}$. Free carteolol, conjugated carteolol, and small amount of p-OH carteolol were found in dosed human urine samples. The conjugated form was being 59.4% of the total carteolol in human urine. The amount of carteolol renal excreted for 72 h after oral dose of 10 mg of carteolol was 49% of the administred dose.

Goals, research direction, and operational structure of the Global Ocean Ecosystem Dynamics (GLOBEC), which is co-sponsored by the Scientific Committee on Oceanic Research (SCOR) and the Intergovemmental Oceanographic Commission (IOC), are described. Following the Joint Global Ocean Flux Study (JGOFS) activities on the lower trophic level in ecosystem during 1980s-90s, scientists have considered the responses of the mid and higher trophic levels to the environmental or climate change. The scientific steering committee of the GLOBEC published the implementation plan in 1999, and the IGBP will support the GLOBEC as one of its core projects for 10 years. The GLOBEC programme has four major components: the research foci, framework activities, regional programmes, and integrating activity. The core of GLOBEC research is the four research foci: retrospective analyses, process studies, predictive and modelling capabilities, and feedbacks. Currently, four regional programmes have been undergoing in the world ocean: Southern Ocean GLOBEC (SO-GLOBEC), Small Pelagic Fishes and Climate Changes (SPACC), Cod and Climate Change (CCC), and Climate Change and Carrying Capacity (CCCC). Also, national GLOBEC programmes were already established in 9 nations.

Special attention has been paid to human chorionic gonadotropin (hCG) for athlete doping control because it stimulates the endogenous production of testosterone and epitestosterone without increasing the T/E ratio which is a doping indicator for the exogenous administration of testosterone. Even though the IOC banned the use of hCG, a detection method has not been decided upon since there are a variety of immunoassay kits available on the market. We evaluated three kits in terms of their performance characteristics. The assay value of the control sample varied depending on the kit, resulting in 198 mIU/ml for the MAIA kit, 172mIU/ml for the IRMA kit, and 143 mIU/ml for the MEIA kit. Considering the IOC inter-lab distribution of results(55-312 mIU/ml) using 27 different kits and the mean value (178$\pm$56 mIU/ml), all three kits are within the range of －15.8% - ＋5.6% of the mean value, which proves them useful for the hCG assay. The MEIA kit resulted in lower hCG values because it detects only intact hCG molecules, in contrast to the other two kits which detect intact hCG and -hCG together. However, it is suitable for screening purposes because of its advantage of being an automated system. When 123 urine samples of athletes were analyzed in 22 batches using this system, the variation of control values fell within $\pm$ 10% of the mean values, and an specimens tested negative with hCG values less than the detection limit of 2 mIU/ml.

This study aimed to examine the coping, self-disclosure, rumination, organizational culture and degree of Posttraumatic Growth(PTG) of firefighters who experienced trauma, and to identify the factors that influence PTG. Data collection was conducted for 103 firefighters working at three fire departments located in Gyeongsang-do. As a result of the study, 46(44.7%) PTGs of medium to high level averaged 58.07 points, and the total PTG average was 44.56 points. The influenced factors affecting PTG in firefighters were emotional-focused coping(EFC), self-disclosure(SD), deliberate rumination(DR) and innovative-oriented culture(IOC).The explanatory power of these factors PTG was 45.9%. In order to promote the firefighters 'PTG, it is necessary to approach of EFC, SE, and DR but also an organizational aspect as well as IOC construction, and these results can be used as an arbitration plan to improve the firefighters' PTG.

The Project of Jordan Research and Training Reactor (JRTR) officially launched in Aug. 2010. JRTR is the first made-in-Korea nuclear system to be built abroad by year 2015, and Korea Atomic Energy Research Institute (KAERI) is responsible for the design of major systems including the reactor core. While the PDCS (Project Document Control System) being operated by EPC company controls all the documents of the whole Project, KAERI is supposed to have its own system for KAERI documents. Meeting such a need; KAERI has implemented a document control for the JRTR Project into already existing ANSIM (KAERI Advanced Nuclear Safety Information Management) system. The documents of JRTR project to be controlled are defined in the PPM (Project Procedures Manual), QAP (Quality Assurance Procedure) and PEP (Project Execution Program). The ANSIM consists of the document management holder, document container holder and organization management holder. The document management holder, which is the most important part of ANSIM-JRTR, consists of the DDA (Document Distribution for Agreement), IOC (Inter-office Correspondence), PM Memo. (Project Manager Memorandum) and cover sheets of design documents. Other materials such as meeting minutes, sub-department materials and design information materials are stored in an independent COP (Community of Practice). This established computerized document control system, ANSIM, could lessen a burden for project management team and enhance the productivity as well.

PM(Preventive Maintenance) can avail the generating unit to reduce cost and gain more profit in a competitive supply-side power market. So, it is necessary to perform reliability analysis on the power systems in which reliability is essential. Thus, to schedule optimal PM planning based on reliability that is defined RCM(Reliability-Centered Maintenance), FMECA(Failure Mode Effects and Criticality Analysis) assessment is very important. Therefore, in this paper, the procedure of FMECA assessment for optimal RCM is proposed by probabilistic approach using real historical failure data of combustion-turbine generators in Korean power systems. The stochastic FMECA is performed based on the effects of probable failure modes of combustion-turbine generating unit.

고유가 시대에 접어들면서 해양석유 가스 산업에 대한 관심이 그 어느 때보다 뜨겁다. 해양석유 가스 시추를 위한 지출은 2011년 650억 달러 규모에서 2020년에는 1,250억 달러로 2배 늘어날 것으로 전망되고 있다. 이러한 해양석유 가스 개발 확대로 해양플랜트 시장은 2010~2015년 최소 4,970억 달러로 전망되고 있다. 이와 더불어 해양작업지원선(OSV) 시장 역시 향후 수요가 지속적으로 늘어날 것으로 전망된다. 이렇게 해양 석유가스 및 연관 산업이 지속적으로 성장할 것으로 전망되면서 브라질, 나이지리아, 앙골라 등 중남미, 아프리카 등 신흥 시장이 각광을 받고 있다. 그리고 글로벌 석유기업(IOC)을 비롯한 관련 업체들이 이 지역에서 탐사 및 개발(E&P)를 통해 시장진출을 위해 경쟁하고 있다. 이에 대해 신흥 국가들은 자국 내 석유가스 산업의 경쟁력을 제고 시키기 위한 일종의 보호조치로서 '로컬 콘텐츠' 정책을 실시하고 있다. 다음은 한국해양수산개발원에서 발표한 "오프쇼어(Offshore)산업 로컬 콘텐츠 정책의 현대적 의의"의 주요 내용을 요약 정리한 것이다.
