  • The purpose of this study is to provide the fundamental data to improve a school building through comparing and analyzing facilities of high schools located in Gyeonggi - do Province on the basis of the Design Indicator for the Korean Educational Buildings. Two types of high schools were examined for this study. Some of them are high schools selected by Korean Ministry of Education as a school equipped with superior facilities and the others are high schools equipped with general facilities. 8 items such as safety, comfort, the function of education, utilization, the public, eco-friendliness, technology performance, economical efficiency were examined by 5 point Likert scale. Findings showed that all facilities of both types of high schools received high ratings in terms of safety, utilization, and technology performance. However, the evaluation index on 'various used outdoor space' and 'public buildings harmonized with surroundings' of the education function of both types of high schools was low, which implies that the facility related to the education function needs to be improved. It infers that facilities are simplified and harmony with surroundings disappears when altering the design of the school building due to the convenience of building and the problem of the budget. Therefore, these need to be primarily controlled. Additionally, in high schools with general facilities, the evaluation index on 'aesthetic interior and exterior design of comfort', 'the responsive space to the demand for teaching and learning of the function of education', and eco-friendless were so low that these factors need to be considered when designing the school building.

  • Microvibration of high technology facilities, such as semiconductor plants and facilities with high precision equipments, due to nearby road and rail traffic has attracted considerable attention recently. In this paper, a preliminary study is conducted for the possible use of various protective systems and their performance for the reduction of microvibration. Simulation results indicate that passive base isolation systems, hybrid base isolation systems, passive floor isolation systems, and hybrid floor isolation systems are quite effective and practical. In particular, the performances of hybrid floor isolation systems are remarkable. Further, passive energy dissipation systems are not effective for the reduction of microvibration. Finally, the protections against both microvibration and earthquake are also investigated and presented.

  • The AC power lines and signal lines of info-communication networks are routed on overhead poles and are highly exposed to lightning strikes. Due to the potential difference between grounding points of AC power lines and signal lines, the electronic equipments connected to the signal lines can easily be damaged by lightning surges. In this work, in order to develop reliable methods of protecting information and communication facilities from lightning surges, the reliability and performance of SPDs (surge protective devices) were experimentally investigated in an actual-sized test circuit. The behaviors of SPDs against lightning surges from AC power lines and signal lines and the coordinated effects of SPD installation methods were evaluated. As a consequence, it was confirmed that the bypass arrester methods and common grounding system are both highly effective.

  • The purpose of this study is to construct the evaluation model for the major science research facilities and equipments to enhance the competitiveness of the science and technology and also to test the reliability and validity of the model. To achieve the purposes, this study theoretically reviews the concept of the major science research facilities and equipments and their characteristics. Through a review of literature, this study draws 11 criteria for evaluating the priorities of the major science research facilities and equipments. These criteria are categorized as two dimensions - 'science & technology' and 'national policy'. The dimension of science & technology includes scientific importance, technological readiness, utilization rate, common utilization rate, and ability of management and operation. The national policy dimension contains degree of correspondence with national science development, imperativeness of national policy, science and technical effectiveness, economic and industrial effectiveness, responsiveness of research demand, and equity among the related institutions. The competitiveness of the science and technology consists of these two dimensions. The evaluation model is established on the framework of criteria. The 18 major science research facilities and equipments are selected through a series of Delphi. The survey of experts (BT, ET, IT, NT and ST) is also implemented to evaluate the 18 major science research facilities and equipments by 11 criteria. The overall results indicate that the reliability and validity of the model are good. The reliability tests show that the five indicators of science & technology and the six indicators of national policy have high internal consistencies. The confirmatory factor analyses reveal that the two constructs - 'science & technology' and 'national policy' - have high convergent and discriminant validity. The correlational analyses also show that the criteria-related validity between them is high. Furthermore, the results of higher order factor analysis indicate that the fit indices of the model are high and suggest a good fit to the data. Based on these findings, the policy implications of the model are discussed.

  • Because the effort to solve space shortage in academic libraries has never been successful, the rapid development of digital technology is being considered as a panacea to revolutionize analog libraries and to open a new era for digital libraries. However, this technology is yet to be perfected. Even with the use of digital technology, we are currently still looking for more space to accommodate newly printed materials and at the same time store valuable resources that are seldomly used. In 1985, Harvard adopted the industrial high-density shelving system into their library. No other retrieving system has proven to be more successful as the Harvard model. Presently, more than 50 colleges have built over 70 high-density library storage facilities. Rice University Library Service Center (RLSC) can be examined as an example of the Harvard-model. This paper will focus on assessing the operating system and architectural requirements of the RLSC which may allow for a more efficient, economical, and fundamental resolution to the library space shortage problem.
