  • Recently domestic building market in the face of 3D, in addition to construction cost increase, materials lack problems and opening a building market to foreign countries, is trying to find out the efficient ways of overcoming these problems. So the necessity to study the permanent form is urgent to escape the problems of constructing human power economy, cost down, noises problem, environmental prevention and efficacy of form work to technical improvement will contribute a practical permanent form in field through economic evaluation of permanent form. In this paper, we compared wood form cost with permanent form cost(made form polymer or fly ash) for frame work

  • Korea Train eXpress(KTX), opened in april 2004 as well as the KOREA RAILROAD sailed in 2005 is on the second take-off stage. In 2004, on the basis of the technical stabilization, management planning centering around business was established, and to attain the object, now there is a increasing necessity for market-information which is necessary for establishment, execution and result analysis of strategies. Therefore, by performing periodical market surveying, getting out of old market strategy making ways of viewing in manager's shoes, we can quickly elaborate market strategies in consumer's shoes on the basis of the market information. And as a necessary consequence, we can expect not only to make efficient use of resources but also to maximize profits of the KTX.

  • Fire accidents in tunnels and underground installations have resulted in significant loss in terms of life and costs. Several large research projects are launched in Europe to find cost effective ways to upgrade and make such installation more robust against accidents from fires and explosions. For one single tunnel, severe fire accidents are rare and operators and users will have very limit experience, when they do occur. There is a trend to solve the problem with high tech instrumentation and monitoring techniques and to rely on the fire brigade to play a major role in the rescue operation. These precautionary measures are very difficult to validate for the severe fires. For protection against the most critical fires, the safety has to be considered in the design of the tunnel and the technical installation validated so that it operates as indented.

  • The interest in environmental issues and the awareness of the importance of environmental education have been increasing. This research was carried out in part to respond to such a change, and it aims to search for and suggest ways to strengthen subject-based environmental education in Korea, the most significant part of the formal environmental education. One of the most important of this research was understanding the present status of environmental education of elementary, middle, and high schools in Korea, which was conducted by the questionnaire survey targeted to teachers on the subject-based environmental education. The survey was carried out comprehensively to include respondents from technical and home economics course as well as from vocational high schools. Through this survey, we gained information on the awareness of teachers and students on the objective, learning-teaching strategies and evaluation of environmental education as well as an understanding of the present status of environmental education in schools of Korea.

  • The skill that meets the intellectual and technical requirements in workplace is called hard skill. The counter part of it is 'softskills' which enhances an individual's interactions, job performance and career prospects. It becomes more necessary skill as society changes. In this paper we first show the demand for the softskill improvement education for engineering major students. Then we introduce a 'softskill improvement education' program developed by the "Center for innovative engineering education" in a University. The contents of the program are chosen by the needs of society, companies that hire our students, ABEEK educational objectives and consulting from professors. To improve the skills we used various activities as tools which are mentioned and introduced. The evaluation of the program results are discussed. We suggest some ways to improve the program.

  • This paper discusses the potential to upgrade the Thai innovation system by university-industry linkages. Our results are structured into three parts. First, the identification of potentials for university-industry linkages (UIL) within the Thai innovation system shows that the re is a wide gap between absorptive capacities of private companies and knowledge production of universities. Second, we present survey results for individual departments at Thai universities showing that UIL are mostly limited to consulting and technical services, hampered by mutual distrust, and maintained to receive an extra personal income. Third, case studies on four typical modes of UIL allow us to discuss various ways to upgrade the Thai IS by UIL in future.

  • The present problem of this country building market in the face of 3D, in addition to a rise in construction cost, materials problems and opening a building market to foreign countries, is finding the efficient ways of overcoming these problems. So the efficacy of form work in technical improvement becomes important through scientific methods of the design and construction as advancement in th study of strength for Permanent form mortar is possible. According to the increment of polymer-cement ration, the degree of bending strength and compressive strength and impact strength increases. The optimum volume content of glass fiber seemed to be about 2.5% considering the distribution of glass fiber, workability and economy.

  • The recent introduction of BIM technology has raised the interest on the BIM quality assurance and management more than ever. This study aims to consider the ways of BIM quality improvement by analyzing the most frequent issues rising from multiple BIM projects. For this purpose, the 12 test models from BIM education program hosted by buildingSMART Korea are investigated based on the requirements in the public BIM guidelines. All the BIM issues generated are categorized by the criteria applied and analyzed for each kind of building element. The results showed that more than half of the issued at least could be cleared out by improving modeling habits and technical guides.

  • Of all the ways that energy is consumed within textile industry, few are as high energy-expending as dyeing process. The energy consumption in dyeing process amounts to 77% of total fuel consumption, 54% of total electricity use. A technical development in terms of efficient saving energy and time as well is required in the process of dyeing textiles. Recently, dyeing experts are investigating new technologies can conserve energy grafting into microwaves, radio waves, infrared lights, etc. Dyeing industry in Korea, however, the research related to energy conservation has been rarely conducted. Accordingly, this study aims to examine the possibility where especially microwaves could be applied to reduce the energy use and enhance dyeing process skill. This study performs the experiment in which microwave is employed as heating condition in dyeing and figures out as color yield being promoted, bathochromic effect would be achieved. Applying microwaves in dyeing process is expected to lower the carbon emission, energy and time wasted, ultimately exalt economic efficiency.

  • Currently, the world has experienced a mass exodus of workforce from the manufacturing industry to service related industry. In addition, the changes of industry structure toward service industry have been gradually accelerated. We have felt that it is time to conduct researches about IT service systematizing and discovering the essence of service itself with scientific and synthetic ways based on Service Science. For Service Science researchers, service identification is regarded as a difficult activity when they contact it for the first time and they want to apply it real environment. In reality, there exist mismatches between business and IT service to identify service since service is identified from the business point of view in Service Science area and it is identified from the technical point of view in IT service area. In this paper, we have conducted researches about service identification placed on the first priority and regarded as difficult area in service-oriented business area. To lessen aforementioned difficulties, we propose procedures and methods for extracting and identifying service in the viewpoint of business process. We conducted case study and comparison with existing researches to verify the applicability and the excellence of our proposal.
