This study was conducted to investigate the effects of a participatory rehabilitation program on sit-rise and rise-to-walk test performances, and perception and motor skills in adults with medically vulnerable individuals and, adults with developmental disabilities in particular. Seventeen adults with developmental disabilities participated in a participatory rehabilitation program using resistance bands and exercise balls, for 60 minutes once weekly over 13 weeks. Their performances were measured before and immediately after the intervention, and 12 weeks after. The findings were as follows. In the sit-rise test, the number of times rising from sitting posture increased after the intervention versus before, but the difference was not statistically significant. In the rise-to-walk test, the performance showed statistically significant difference over time, and the post-hoc test showed a significant effect after the intervention versus before. There was no significant difference in perception and motor skills. In sum, the participatory rehabilitation program positively influenced dynamic balancing related to functional activities but had no significant effect on perception and motor skills, which is related to motor control and motor learning. It is suggested that to increase the participation in community activities, reduce fall risk, and improve dynamic balancing abilities in adults with developmental disabilities, participatory rehabilitation programs should be utilized to promote the physical wellbeing.

Purpose: This study was conducted in order to closely examine the effects on bone mineral density and health promotion behaviors following the intervention of a 20-week Thera band exercise program targeting elderly women. Methods: This study is a pseudo-experimental research with a pre-and-post design in a single group that examined the effects after the intervention of Thera Band Exercise for 20 weeks targeting 31 elderly women over 60 years of age who visit a Senior Welfare Center located in K city. It analyzed subjects' general characteristics using error and percentage, health promotion behavior, and a bone density aspect using the mean and standard deviation, as well as a change in the health promotion behavior and bone density, before and after exercise with Paired t-test by using the SPSS 18.0 program. Results: The effect of the Thera band exercise program on bone mineral density was reduced (t=8.140, p<.001) gradually after 20 weeks of exercise compared to the pre-exercise period. The health promotion behavior before and after exercise showed the significantly increasing outcomes (t=3.26, p=.003). Conclusion: There is a limitation to a direct rise in bone mineral density with the use of Thera band exercise intervention in the elderly. A change in health promotion behavior before and after exercise increased significantly. Thus, it was confirmed that taking exercise leads to a gradual rise in health promotion behavior. Hence, it understood that continuous exercise is useful and brings about a positive change in promoting health maintenance in elderly women.

The purpose of this study was to examine the effect of a program geared toward improving elderly people's oral function. After a program was provided to the selected elderly people free of charge for three months, they were asked to rate their own oral function to see whether they underwent any changes after their participation in the program, and their oral function was tested to obtain objective data. The collected data were analyzed by the statistical package SPSS WIN 18.0. The findings of the study were as follows: As for changes in their self-rated indicators of oral function, they faced less troubles in most of the oral function items after they participated in the program, and there were statistically significant differences in some of the items. As a result of making an objective evaluation of their oral function, they underwent a little change in salivary flow rate from 1.19 to 1.30, though the change was not statistically significant. In terms of opening, they showed a statistically significant rise of scores from 4.22 to 4.53, and they also showed a statistically significant rise of scores in pronunciation from 30.52 to 38.88. Regarding satisfaction with the program, they gave 4.48 to the program, which implied that they were greatly satisfied with the program. The abovementioned findings suggest that oral health experts and program providers should try to encourage elderly people to keep on taking oral health programs with interest. Currently, oral exercise programs are conducted in some public health centers and in the field of clinical dentistry, and it's required to offer more oral exercise programs as community exercise programs for the elderly.

Increasingly, mixed-use, multi-program complexes are emerging as the standard development model around the world. As their prominence grows, these projects are becoming increasingly complex. Program adjacencies are ever more intertwined as developers (and the architects who support them) are becoming more comfortable blurring the traditional boundaries between office, retail, residential and hospitality. This article discusses a second generation of mixed-use projects that embrace this hybridization, honing in on supertall architecture, their hybrid program offerings, and innovative sky lobbies. It concludes that programmatic advancements will continue to expand and find integration within single structures, both repositioned and built from the ground up.

Recently, the demand for Building Information Modeling (BIM) construction drawings and specifications has increased rapidly. Many countries have also started to implement BIM. The BIM implementation can change the design flow of buildings including high-rise buildings. Against this background, many companies are focusing on the development of BIM software. BIM involves a three-dimensional CAD program that can examine the placement of ductwork and machinery. It significantly increases the efficiency of a mechanical design through data unification using standard Industry Foundation Classes (IFC). In addition, BIM functions as a database to simplify the use of simulation technology for designing air-conditioning systems. To further develop BIM, it is important to know the expectations of mechanical engineers who will become frequent users of BIM in the future. A survey was conducted among Japanese mechanical engineers using a questionnaire to analyze the expectations of mechanical design using BIM. The results show that many respondents strongly recognize BIM as a three-dimensional CAD program. However they also expect that BIM can help the optimization of their design works and enhance design functionality by running simulations utilizing BIM.

This paper describes analysis of risk voltage for grounding electrode where earth leakage current is injected. To assess risk voltage of grounding electrode, the grounding simulator and CDEGS program were used to obtain measured data and theoretical results of this study. The grounding simulator was composed of a hemispherical water tank, AC power supply, a movable potentiometer, and test grounding electrodes. The shapes of grounding electrode model was ground rod. The potential rise was measured by grounding simulator, and the touch and step voltages were computed by CDEGS program. As a consequence, the potential rise of ground rod abruptly decreases with increasing the distance from the grounding electrode to the point to be tested. The touch voltage above the ground rod was low, but the step voltage was high. The measured results were compared with the computer calculated data and were known in good agreement.

When the lightning current is injected to the ground system of information and communication facilities, analysis of the transient potential rise in the ground system is one of main factors to effectively design the ground system. The performance of grounding systems is normally estimated with the grounding impedance and the transient potential rise which represents the electrical characteristics of the grounding system. The method for calculating the grounding impedance depending on the injection point of the lightning current was proposed. The delta-gap source model was proposed to calculate the grounding impedance in the case that the lightning current is injected to the center of the horizontal ground electrode. A new program which is possible to apply the frequency-dependent soil parameters using the Debye model was developed, because a commercial program for analyzing the performance of the grounding system can not apply to the frequency-dependent soil parameters. The experiment was carried out to confirm the availability of the simulation results with the same condition. Finally, the transient potential rises of a horizontal ground electrode depending on the lightning current waveforms were analyzed by using the results of the grounding impedance which is associated with the frequency-dependent soil parameters.

The purpose of this study was to design a development frame for multicultural science program and develop a corresponding program using the frame. This study organized a development frame to design a multicultural science education program based on the culturally responsive teaching theory. This development frame consisted of the elements of purpose, teaching examples, teaching and learning methods, and assessment. This program consisted of the guideline for class teaching courses, reading materials, student worksheet, and teachers' reference materials. Based on this development frame, a multicultural science education program was developed, which was comprised of seven activities for elementary and middle school students. Each activity of the program included the concept and inquiry related to science education. In particular, by connecting the concept of science with the cultural characteristics of various countries, the activity made students aware of cultural diversity and the commonness of science principles. Compared to other subjects, the science education field has not actively undertaken studies on multicultural education. In term of dealing with universal principles, science education is suitable for making students aware of commonness. Accordingly, this gives rise to the need to draw cultural characteristics based on basic studies such as the analysis of science textbooks in various countries and develop culturally responsive programs utilizing the outcomes.

The paper proposes alternatives for fire safety in architectural planning through heat-smoke distribution related to openings so that we decrease casualty and property loss by fire and lay a great emphasis on building high-rise apartments with consideration of fire safety in Korea. An analysis program(HFA-Heat Fluid Analysis) is built to perform simultaneously numerical analysis and experimental analysis on rooms, units and buildings. In consequence, on the first, fire prevention methods are required to be set up related to openings for design rooms since the flow of heat and smoke is influenced by the type of openings in high-rise apartments. Second, the numerical analysis showed that different planning types cause to show differences in the spreading time of heat and smoke to design the units of high-rise apartments. On the third, each unit building showed different fire behavior depending on openings by numerical analysis and small scaled experiment on heat and smoke flow.
