It is very important to manage the risk in building construction because construction process has too many internal risk compared with others. So construction managers need more developed risk management system than the Present. While the study for the solution and management of generated risk is comparatively enough, the effort to confirm the risk of construction phase on pre-construction phase haying an major effect on total duration, is insufficient. For supporting the schedule risk management of pre-construction, this study suggests the reclassified risk breakdown structure and the investigation form for advance preparations on pre-construction Phase, which help the Poorly experienced construction manager to make more correct decisions and efficiently to execute risk management.

Objective: This study aims to analyze occupational accidents of parking lot attendants by parking lot type. Background: Recently, efforts are made to analyze accident characteristics by occupation type targeting the workers engaged in the same work. Method: This study analyzes 303 occupational accidents of parking lot attendants occurring from 2010 to 2012. Parking lots are grouped into two groups according to the work environment. One is public/ground type which comprises road side or open area parking lots and the other is building/mechanical type which comprises a multi-story parking building with connecting ramps and/or mechanical parking system. The characteristics of occupational accidents by parking lot type are analyzed. Results: Accident characteristics showed the difference between public/ground type and building/mechanical type on the size of enterprise, age, gender and work experience of the injured. Also the accident type, source of accident and parts of body affected are different between the two parking lot types. Conclusion and Application: The findings of accident characteristics according to parking lot types can be used as baseline data for establishing systemized preventative policies for occupational accidents of parking lot attendants.

The visualization of three dimensional geophysical data is forcing a revolution in the way of working, and allowing the discovery and production of hydrocarbons at much lower costs than previously thought possible. There are many aspects of this revolution that are behind the scenes, such as the database structure, the storage and retrieval of data, and the exchange of data among programs. Also the user had changes where the interpreter (or manager, or processor) actually looks at and somehow interacts with the data. The use of opacity in volume rendering, and how its judicious application can assist in imaging geologic features in three dimensional seismic data. This revolutionary development of new technology is based on the philosophy of synergy of inter-disciplines of the oil industry. Group interaction fostered by large room visualization environments enables the integration of disciplines we strive for, by putting the petrophysicist, geologist, geophysicist, and reservoir engineer in one place, looking at one image together, without jargon or geography separating them. All these tools developed in the oil industry can be applied into the civil engineering industry also such as the prior geological and geophysical survey of the constructions. Many examples will show how three dimensional geophysical technology might make a revolution in the oil business industry now and in future. This change can be considered as a fusion process at data, information, and knowledge levels.

Purpose: The purpose of this study was to explain the role transition process to nurse case managers (NCMs) for Medical-aid beneficiaries in Korea. Methods: Fourteen NCMs were interviewed regarding their experiences of becoming proficient in the new role of case manger. Data were analyzed through the application of grounded theory. Results: 'Taking root in a barren land' was the core category explaining the role transition process of NCMs. They engaged in four stages: launching, trial and error, proficiency, and wait-and-see stages. NCMs showed not only fear but also passion for case management practice. Despite their passion and effort, NCMs went through a period of trial and error. After becoming skilled, NCMs went through a stage of wait-and-see often because of job insecurity related to temporary position or few opportunities for promotion. Factors influencing NCMs' role transition process included their understanding of client characteristics, belief in case management, and support from their colleagues and families. Conclusion: NCMs experience many challenges in the process of becoming proficient NCMs. To help with their role transition, there is a need for education programs, preceptorship programs, research on their roles and functions, and regulation for securing NCMs' employment and career stability.

The importance of selecting the strategic research field is increasingly emphasized by research manager and technology policy-maker in perspective of the strategic allocation of R&D resources, employing the R&D personnel, and formulating technology policy. Among various methods for selecting the strategic research field, it is, however, very difficult to find the method that involves the path-dependant trend, and interdisciplinary nature of technology development. This study suggests modified technology cluster analysis (TCA) as a method for selecting strategic research field in order to include the recent technology trend in quantitative approach. TCA is the method that groups the near technologies of which the innovation pattern is similar. TCA model can be a very necessary method for multidisciplinary government research institutes (GRIs) which conduct multi research field with forward oriented positioning. It is more difficult for them to select the strategic research field mainly due to their diversity and intangibility of research scope. In this study, we applied this method to Korea Institute of Science and Technology (KIST) which represents the most adequate research institute in terms of research diversity and forwardness. As a result of the application, we found that seven main technology groups come from TCA analysis, coincide with the technology topics of KIST's recent R&D planning. Even though this method designed for multidisciplinary research institutes, but it also can be used for establishing the research strategy of other (private or public) Research Institute which have the similar mission and scope of research.

The potential risks, involved with the management of a library, may cause a tremendous economic loss, so require a systematic management. The rist management process, consisting of risk identification, risk measurement selection of risk treatment methods, implementation, and monitoring and evaluation, suggests the use of insurance to deal with property risks, liability risks and personnel risks. For the systematic risk management of a library, risk manager should be appointed to be responsible for program development and insurance purchase. The limited coverage of library risks, provided by the school cooperative society, should be supplemented through development of insurance products. Further study is required to improve the library risk management and the application of insurance in a systematic and realistic way.

Success of the construction companies is based on the successful completion of projects within the agreed cost and time limits. Artificial neural networks (ANN) have recently attracted much attention because of their ability to solve the qualitative and quantitative problems faced in the construction industry. For the estimation of cost and duration different ANN models were developed. The database consists of data collected from completed projects. The same data is normalised and used as inputs and targets for developing ANN models. The models are trained, tested and validated using MATLAB R2013a Software. The results obtained are the ANN predicted outputs which are compared with the actual data, from which deviation is calculated. For this purpose, two successfully completed highway road projects are considered. The Nftool (Neural network fitting tool) and Nntool (Neural network/ Data Manager) approaches are used in this study. Using Nftool with trainlm as training function and Nntool with trainbr as the training function, both the Projects A and B have been carried out. Statistical analysis is carried out for the developed models. The application of neural networks when forming a preliminary estimate, would reduce the time and cost of data processing. It helps the contractor to take the decision much easier.

무선 인터넷 환경에서 무선 인터넷 브라우징을 지원하는 휴대폰 단말기는 각 단말기 종류별로 표시 가능한 줄 수, 화면 넓이, 칼라 지원 여부 등과 같이 다양한 표현 능력을 갖고 있음에 따라, 휴대폰 단말기를 통해 클라이언트에 의해 요청된 해당 컨텐츠는 각 단말기의 표현 능력에 따라 응용 서버에 의해 적절하게 변환되어 클라이언트에게 제공되어야 한다. 그러나 변환 작업은 처리 시간이 매우 많이 소모되는 작업이므로 캐쉬를 이용하는 방법이 효율적이다. 그러나, 무선 인터넷 환경에서는 다양한 종류의 휴대폰 단말기가 존재하므로 변환된 컨텐츠는 오직 그 컨텐츠를 요청한 단말기에만 유효하도록 캐쉬에 저장되기 때문에 캐쉬에 대한 적중률이 매우 떨어질 수 있는 문제점이 있다. 본 논문에서는 무선 인터넷 환경에서의 이러한 캐쉬의 약점을 극복하기 위해, 모바일 환경의 응용 서버에서 다양한 단말기를 위한 컨텐츠 변환을 지원하면서도 캐쉬의 적중률을 높일 수 있는 방법을 제안하며 이에 대한 설계를 논한다.
