This paper describes the importance of incorporating the titre-dependent deformation behaviour in the design and construction of tunnels in swelling rocks. Two tunnel projects, in which authors got involved in Canada, are chosen to demonstrate the importance. In diversion tunnels for Oldman River Dan Projects time-dependent deformation characteristics of the mudrocks obtained from teat tunnel program were neglected in the design and construction of the tunnels and several sectional of concrete lining in tunnels were cracked extensively. In SABNGS No.3 Projects an extensive experimental program was carried out to study time-dependent deformation behaviour of highly swelling Queenston shale, with the air of establishing the constitutional relationship for the rock-structure time interaction analysis.

This paper examines the correlations between user characteristics and their perferences for two selected features of Web-based OPAC systems. User characteristics identified in this study were age, gender, educational status, computer skills and OPAC experience. Usability features included interaction styles, character and image on screen, browsing and navigating style, screen layout, and ease of learning, whereas availability features attended to availability of information, quality of information and up-to-date information. Individual variables and features are described, and the correlation between the variables and the features are explored using Pearson's correlation coefficient(r). Although based on a small-scale sample survey, a considerably large number of statistically significant correlations were found between the users' characteristics and the selected evaluation features of interactive Web-based OPACs. From these observations, it seems to be suitable to recommend that system designers should make a more considered appraisal of the users' demographic characteristics in the design of the new generation of OPAC such as in user-tailored interactive Web-based OPAC systems.

The Burj Dubai Project will be the tallest structure ever built by man; when completed the tower will be more than 700 meter tall and more than 160 floors. The early integration of aerodynamic shaping and wind engineering considerations played a major role in the architectural massing and design of this residential tower, where mitigating and taming the dynamic wind effects was one of the most important design criteria. This paper presents a brief overview of the structural system development and considerations of the tower and discusses the construction planning of the key structural components of the tower.

This paper presents a study on risk analysis in terms of contractor's costs in construction phase in which Crystal ball (software of Decisioneering, UK) has been utilized as a main tool. To realize it, a questionnaire survey has been carried out to identify the dominant factors that strongly influence contractor costs in Vietnam. Based on results of questionnaire investigation, the survey identified three factors which were duration of each construction task, costs of reinforcing steel, and cement. Then a spreadsheet model was created in order to analyze risks. The study also indicates that the cost of reinforcing steel and cement are the cause of risks for contractors. According to the suggested model, contractors may foresee the probability of completion within the approved budget, and the possibility of earning in accordance with owner's payment conditions.

In the meantime hospital system of Korea has institutionally performed its errand in stable circumstance, however the system now faces with new environment of change of customer's satisfaction, of regime, deepening of competition, and opening market. Under the rapidly and complicatedly changing circumstance, the hospital system is required to promote getting a dominant position in the competition, enhancing outcome, creating value added, and customer satisfaction in both internally and externally likewise other organizations, as they continuously introduce a knowledge management and originate, accumulate, and put the knowledge to practical use. This organization capacity of knowledge management involves a process of management that requires great change of all organizations and individuals and it is brought up through four steps which are Initiation, Propagation, Integration, and Networking. The main factors of successful knowledge management are intension of the chief executive officer(CEO), organizational culture, appraisal and compensation of work, knowledge controlling system, and organizational structure, and each of these five stage has got different characteristic. To be successful by introducing knowledge management, hospital organization should be based on these premises. Not only CEO or the director of a hospital, but also the constituent members should be fully aware of knowledge, the characteristic of knowledge management, and successful factors of this operation. Should understand step-by-step characteristic of knowledge management, therefore able to analyse a situation of specific hospital and see which step corresponds to that hospital. By analysing, constituents should make up for the weak points and ready to move on to next step. CEO or the director of a hospital should be aware of knowledge management as a strategic factor which is able to get a dominant position in the rapidly changing environment, and also it should be firm in the director's intention to introduce the knowledge management into the hospital. By continuously carrying out education and training constituent members, the director of a hospital should promote their interest and participation in knowledge management, and build an organization culture that ultimately creates, accumulates, shares, and put the knowledge to practical use. The hospital organization needs to systematize an institution of objective compensation that corresponds to objective appraisal of knowledge management outcome. The hospital ought to build knowledge controlling system in stages, in order to take the initiative in rapidly changing environment. By considering the characteristic of hospital system, it is required to change the organizational structure into self-managing team which is a sort of horizontal structure that allows members to make decisions and take the responsibility by themselves. The limitation of this study is experimental study. Positive investigation about successful factors of hospital knowledge management and characteristic of each steps is expected with following study.

이 논문은 지역방송 내부 식민지화의 중심에 사장선임을 위시한 지배구조가 자리하고 있다는 데 주목했다. 그 실체를 파악하기 위해 1990년대 중반에서 2015년 사이 MBC 지역계열사 17개사와 지역민방 9개사, 총 26개 지역방송사의 사장과 주주 이사 구성을 취합 분석했다. 이와 함께 지역방송 인력과 운영현황, 그리고 그 문제점을 검토 논의했다. 이를 통해 지역방송의 내부 식민지화가 작동하는 방식을 규명했다. 지역MBC는 서울본사의 필요를 우선순위에 둔 지배구조가, 지역민방은 소유와 경영 분리 미흡에 따른 대주주의 전횡이 제작과 인력 부문의 투자 제약요소로 작용하면서 내부 식민지화가 가동되고 있었다. 이어 이 논문은 지역방송 사장선임을 비롯한 지배구조 개선방향을 법 제도와 방송사 자율규제 차원에서 제안했다. 법 제도적으로는 방송법상의 지역방송 편성규약 단서조항 신설을 비롯해 관련법령인 지역방송발전지원특별법, 방송광고판매대행 등에 관한 법률, 방송통신위원회의 설치 및 운영에 관한 법률 개정안을 구체적으로 제시했다. 자율규제로는 지역MBC의 경우 사장선임추천위원회 운용과 방송문화진흥회 이사의 3분의 1을 지역인사로 구성하는 방안, 지역민방은 소유와 경영의 분리를 출발점으로 한 공공성 회복과 사장 사외이사추천위원회 도입 등을 제안했다.

새로운 정보기술이 등장하고 교류가 늘어나면서 과거 간명해 보였던 개념과 현실의 관계가 다변화되고 모호하게 변하고 있다. 가상공간(cyberspace)의 출현은 가상장소(cyberplaces)가 존재함을 뜻하며, 또한 현실 세계의 공간과 장소 간의 관계에 못지 않게 가상공간과 가상장소의 관계도 복잡할 것임을 암시한다. 정보기술을 활용하여 만들어 낸 세상의 여러 장소나 과정의 복제품, 즉 가상현실(virtual reality)은 이러한 관계들을 탐색하는 실마리를 제공하낟. 그러나, 실제가상(real virtuality), 즉 정보기술을 이용하여 현실세계의 장소에 대한 경험을 강화하면 공간과 장소의 관계에 대하여 더 깊은 통찰을 얻을 수 있다. 실제가상은 지리학자로 하여금 그가 하는 일의 효율성을 높이고 영역을 넓히는 데 여러 가지 참신하고 강력한 도구를 마련해 준다. 실제가상이 널리 쓰이게 되면 지리학자들의 연구와 교육, 응용 분야에서 자료, 분석기법, 이론을 다루는 양식이 달라질 것이다.

Lifting plan in conjunction with the overall construction plan will be established. It is being created by executive director of the Corporation and other such as an experienced site manager. But, written lifting plan based on the limited information and experience is causing some problems such as decreasing productivity, workability loss, delay. The reasons for the problems are lack of prediction of construction execution, inappropriate materials on the past performance, individual experience, limits of knowledge, lack of technical materials, shortage of advisor. Therefore, to solve the problems, we have to overcome the situation in which we depends on lifting planner's experience and intuition, limited information by accumulating objective and reliable materials. Because unorganized lifting plan will lower efficiency of lifting equipment and make reducing construction period difficult. In this study, influence factors on lifting plans will be derived through reviewing literatures and lifting plan cases. Derived influence factors will be classified as components and classes, classified influence factors are assessed suitability. Also, Decision making items are derived from the factors. Finally, tower crane lifting plan process will be suggested from the result.

This paper presents a study on the impact of variation of construction material prices on the feasibility of building projects in Vietnam. The paper makes use of Monte-Carlo simulation for financial risk analysis of net present Value (NPV) and internal rate of return (IRR). To well illustrate the influencing, a case study is presented. The research results show that there is a strong correlation between steel prices, gold prices, and $US exchange rate. Outputs of statistics also reveal that the concurrent variation of prices of cement, steel, sand, brick, formwork and stone has strongly negative impact on NPV and IRR of building projects. The results also indicate that the proportion of steel cost to total construction cost is 17.95% which is the cause of risks for the feasibility of building project in Vietnam. The paper stresses that feasibility study of building project must integrate the impact of construction materials prices in order to mitigate risks in developing countries as Vietnam.
