The purposes of this study were to investigate the impacts of interactivity, site stickiness, and switching barrier on intention to use. For this purpose, the study tested covariance structural model which set relationships among independent variable(interactivity), meditated variables(site stickiness and switching barrier), and dependent variable(intention to use). The data were collected from a sample of 239 internet shopper of college female students. The covariance structural model and research hypothesis analyzed by using SPSS 16.0 and AMOS 5.0 program. The results are as follows: First, the structural model is accepted significantly. Second, interactivity had a positive influence on site stickiness, switching barrier, and intention to use. And it was found to have a indirect effect on intention to use through site stickiness and switching barrier. Third, site stickiness had a positive influence on switching barrier. Forth, site stickiness and switching barrier had a positive impact on intention to use.

The insertion loss of a noise barrier comes from the effects of diffraction, transmission loss, absorption coefficient and attenuation by direct propagation. The noise level after the noise barrier, differs reatly from the diffraction on the upper part of the barrier. Maekawa, furze and Anderson presented a empirical formula for calculating the diffraction of a semi infinte screen shaped noise barrier. In this syudy, Noise reduction performance software was developed for the proper design and assessment of new plastic barrier . Predicted sound pressure level from using the software is compared with the site-measurement results to verify the noise reduction performance and feasibility of prediction software for insertion loss of noise barrier.

This study is to understand fallible point on the step of design, construction and management, and suggest an improvement measure for the convenience of elderly through the field survey. The field survey on convenience facilities for the disabled of Senior Welfare Center in Chung-Buk Area was performed on approach to main entrance, parking lot, main entrance area, entrance door, passage, stair, elevator and toilet. It was discussed that barrier free design should be considered of main user's group and use pattern. Consequently, important points requiring circumspection at the step of design and construction was suggested.

Purpose: The concept of the Barrier-Free Design has steadily expanded into a basic principle of design, which can provide safe and convenient lives not only limited to the disables, elders, and pregnant women, but also to all members of the society. This is what we now know as the Universal Design. In other words, Barrier-Free Design for all is Architectural Approach of Universal Design. Thus, as a future-oriented alternative to school facilities according to social change, this study suggests basic direction of school building planning and concept of universal design considering school facilities characteristics. Methods: The characteristics of school facilities are understood from the perspective of Universal Design. In addition, a survey is conducted to identify the current state of school facilities. Result: Findings from this study are as follows. First, Universal Design of School Building is an integrated characteristic. Integration is intended to create and manage an integrated environment instead of an individual and one-time approach to installation and maintenance of convenience facilities. Second, It is a flexible characteristic to be sustainable. In other words, they aim to be selectable to respond to change. Third, It is a characteristic of accumulation of outstanding cases. This means that not only individual schools but also entire school spaces will be applied to Universal Design to form a virtuous circle of environment improvement. Implications: The results of this study may serve as a basic concept in the design of school buildings.

Noise barriers are being used more often to solve problems of noise pollution from traffic noise. Several types of noise barriers are being installed to increase the cost-effectiveness of noise barrier installation. In this study, the insertion loss is analyzed to evaluate the effectiveness of the noise barrier by using the BEM. In order to check the validity of the BEM, the BEM and Lam's theoretical analysis are compared with measurement, which is performed in the anechoic chamber for the 1/10 scale-down model, and good agreements are obtained. By using the two dimensional boundary element method, the insertion loss is calculated and analyzed for several typical noise barriers such as the vertical barrier, the barrier with an oblique edge on top, the T-shaped barrier and the barrier with interference device on top. With these analyses, it is possible to design more cost-effective noise barriers appropriate for a particular area.

For the foundational study on automatic review of the barrier free Environment certification for the socially disadvantaged using BIM modeling information, we first confirm the need of the automatic review by analyzing the barrier free Environment certification an by investigating the existing studies on barrier free Environment certification. After that, we select a primary approach for our research by investigating the related works such as automatic review of the building code. As a next step, we generate the BIM modeling information, extract the classification system, analyze and extract items in the barrier free Environment certification according the extracted system, compares the items with the BIM generation information, and allocate them. And, we showed the potential usability of automatic review by deriving a process to prepare the ruleset structure for the automatic review and to prepare a criteria for BIM modeling guide.

Insulation systems in Liquefied Natural Gas Carriers (LNGC) are vulnerable to sloshing impact and fatigue loads because of waves. If gas leaks into the primary barrier, the Flexible Secondary Barrier (FSB) prevents the leakage of gas in this system. Fatigue strength of the FSB largely depends on the behavior of composite materials. In this study, a new system is applied to the FSB using aramid fiber to improve the fatigue strength of the secondary barrier, with the intention of replacing conventional E-glass fibers. The manufacturing method involved varying the ratio of the aramid fiber to the E-glass fiber for optimum design of the FSB. The fatigue tests results of the secondary barrier using aramid fiber were superior to that using E-glass fiber. The statistical analysis is performed to obtain the fatigue test results and estimate the probability of failure as well as the design guideline of LNGC secondary barriers.

This paper investigates the insertion loss of nosie barrier with a interference device. The efficiency of the conventional interference-type noise barrier depends on specific frequency. Thus this study is performed to improve the efficiency of the nosie barrier in the range of broadband frequency, by changing the shape of interference device and adding the channel with various depths. The boundary element method (BEM) is used to predict the insertion loss of noise barrier. Two-dimensional boundary element model is created to simulate the performance of long barrier with a line source.

Noise barrier is used for noise reduction method of traffic noise. The length and the total cost of that are increased in this national area. But, a maintenance management of noise barrier is not systematic, and the guideline of that is not prepared for maintenance mannual. The situations of existed installation and management of noise barriers installed at 3,619 positions were investigated by questionnarie and direct field survey. And comparisons with foreign management guideline of noise barrier were carried out. The results show that the improvement methods of maintenance management system such as practical checklist and required items for management of noise barrier were suggested.
