Price fluctuation contract is imperative and of paramount essence in the construction industry as it provides adequate relief and cushioning for changes in the prices of input resources during construction. As a result, several methods have been devised to better help in arriving at fair recompense in the event of price chang es. However, stakeholders often appear not to be satisfied with the existing methods of fluctuation evaluation, ostensibly because of the challenges associated with them. The aim of this study was to identify the challenges to usage of building construction cost indices in Ghana. Data was gathered from contractors and quantity surveying firms. The study utilized survey questionnaire approach to elicit responses from the contractors and the consultants. Data gathered was analyzed scientifically, using the Relative Importance Index (RII) to rank the problems associated with the existing methods. The findings revealed the following among others; late release of data; inadequate recovery of costs; and work items of interest not included in the published indices as the main challenges of the existing methods. This study will provide useful lessons for policy makers and practitioners in decision making towards the usage and improvement of available indices.

현대 과학기술연구개발에서 데이터의 수집, 큐레이션, 분석, 시각화의 효율화는 과학기술발전의 중요한 요소이다. 데이터 집중연구에서 이러한 과학데이터의 가치는 절대적으로 필요하다고 할 수 있다. 과학데이터의 생산량은 기하급수적으로 증가했지만 데이터를 수집하고 배포할 수 있는 수단을 마련하는 측면에서 보면, 현재 분야별로 과학데이터의 개별적인 활용 체제만 운영되고 있어 걸음마 단계이다. 이에 본 논문에서는 국가차원의 국가 과학데이터센터 구축의 경제적 파급효과를 한국은행(2009)의 산업 연관분석을 이용하여 생산유발효과, 부가가치유발효과, 취업자유발효과 및 전 후방연쇄효과로 나누어 분석하여 국가 과학데이터센터 구축에 대한 경제적 타당성을 검증하고자 한다.

A safety assessment code, called SAGE (Safety Assessment Groundwater Evaluation), has been developed to describe post-closure radionuclide releases and potential radiological doses for low- and intermediate-level radioactive waste (LILW) disposal in an engineered vault facility in Korea. The conceptual model implemented in the code is focused on the release of radionuclide from a gradually degrading engineered barrier system to an underlying unsaturated zone, thence to a saturated groundwater zone. The radionuclide transport equations are solved by spatially discretizing the disposal system into a series of compartments. Mass transfer between compartments is by diffusion/dispersion and advection. In all compartments, radionuclides ate decayed either as a single-member chain or as multi-member chains. The biosphere is represented as a set of steady-state, radionuclide-specific pathway dose conversion factors that are multiplied by the appropriate release rate from the far field for each pathway. The code has the capability to treat input parameters either deterministically or probabilistically. Parameter input is achieved through a user-friendly Graphical User Interface. An application is presented, which is compared against safety assessment results from the other computer codes, to benchmark the reliability of system-level conceptual modeling of the code.

One of the limitations of conventional ASCI for high-power induction motor drives is the high voltage that is produced in the commutation capacitors during the current commutation from one phase to another. Since the capacitor voltage appears directly on the semiconductor components, it increases their required voltage ratings. Also, the high-voltage spikes generated at the motor terminals may cause damage to the motor insulation. And we investigated how de input power is increased or decreased according to size of de link inductor. In this paper, de link inductor and clamping capacitor in GTO inverter suitable for induction motor drives are propose through experiment.

A quality assurance safety assessment database, called QUARK (QUality Assurance Program for Radioactive Waste Management in Korea), has been developed to manage both analysis information and parameter database for safety assessment of low- and intermediate-level radioactive waste (LILW) disposal facility in Korea. QUARK is such a tool that serves QA purposes for managing safety assessment information properly and securely. In QUARK, the information is organized and linked to maximize the integrity of information and traceability. QUARK provides guidance to conduct safety assessment analysis, from scenario generation to result analysis, and provides a window to inspect and trace previous safety assessment analysis and parameter values. QUARK also provides default database for safety assessment staff who construct input data files using SAGE(Safety Assessment Groundwater Evaluation), a safety assessment computer code.

Norwegian technology related to preinvestigations, planning, design and construction of large underground caverns is wellknown worldwide. However, so far this technology is only slightly verified through scientiffic reports and documentation. The "Rock cavern stadium" research program is an interdisciplinary program related to the ongoing building and future use of Gjovik Olympic Subsite which is the largest cavern in the world for public purposes with a span of 61 meters and a height of 25 meters. The estimated budget for this program is about USD 4 million which is made possible through grants from The Royal Norwegian Council for Scientific and Industrial Research as well as through contributions from Norwegian and Swedish companies that are participating. The program is carried out in collaboration with The Foundation for Scientific and Industrial Research at the Norwegian Institute of Technology. The Norwegian Geotechnical Institute and The Eastern Norway Research Center. The research program will continue until the end of 1994 to ensure that input comes from a full period of use in this stadium with different activities like exhibitions, conferences, concerts etc being included as verification through full-scale measurements and observations. The research program has five subtasks. Three of these are related to subjects like Energy consumption. HVAC installations. Fire safety design, Engineering geology and Rock mechanics, Environmental aspects. The fourth subtask is concerned with the collection of basic data, results and experience from these three subtasks to provide a basis for national Norwegian guidelines related to this interdisciplinary subject area. The guidelines will first be presented as a manual for planning and engineering purposes. The realization of this research program is a unique opportunity to enhance the expertise that has been acquired from this cavern stadium. By involving research in this extraordinary project from the excavation and building phase to its subsequent use. this will give the participants know-how and expertise which is very much in demand internationally. The coordination of the international activities between the participants as well as preparation of participations and presentations in international conferences and symposium are included in the fifth task of this national research program.

The purpose of this paper is to survey the definition and scope of English Education as an academic discipline or science, relating to English linguistics, linguistics and applied linguistics. English Education has come to be regarded as fulfilling its true function when it is based on the solid scientific principles and methods of such related sciences as linguistics, English linguistics, psycholinguistics, sociolinguistics, sociology, psychology and pedagogy. English Education is, therefore, an independent and specialized applied science, interrelated with the sciences mentioned above. Thus, English Education is defined as an academic discipline which is concerned with the concrete teaching and learning of English, and which is based on the scientific methods, applications and evaluations of English. As a science, English Education has three elements: content, process and methods. Content, which concerns input, consists of the fundamental interrelated sciences and English language skills. Process refers to research methodology and analysis. Methods are the application of the theories and the processes.
