With the recent diversification and complication of buildings, the functions of building are also developing. As much as the development of buildings, the machine or equipment used for them is also developing. Thus, all sorts of domestic/foreign industrial facilities and fire stations in the whole nation are using the electric shutter that could meet the insulation just like the exterior wall of general buildings, for bringing-in/storage and crime prevention/fire prevention. Currently, various types of electric shutters are used. Such wrong operation and poor management are causing many panel-falling accidents. This study researched the reduction of electric shutter panel-falling risk by reviewing the domestic/foreign laws and standards, and researching the new safety equipment. First, the causes for falling and accident types were drawn by analyzing the cases of electric shutter accidents. After that, a checklist as the measures for reducing the falling of electric shutter in building was suggested by analyzing the items for the inspection of electric shutter.

Purpose : The purpose of this study was conducted to compare the fear of falling, self-efficacy and fall prevention behavior according to the fall experience of the elderly. Methods : The subjects of this study were 162 elderly in B metropolitan city. The data collection period was from September 10th to November 30th of 2018. The collected data was processed using SPSS 21.0 and was analyzed using descriptive statistics, t-test, ANOVA, Scheffe's test. Results : The mean scores for fear of falling according to the fall experience and no fall experience of the elderly were 2.28±0.63 and 1.84±0.64 respectively and the results showed that fear of falling (t=4.26, p<.001) and self-efficacy of falling (t=3.88, p<.001) were significantly different between the two groups, but the mean scores for fall prevention behavior according to the fall experience and no fall experience of the elderly were 1.63±0.20 and 1.67±0.17 respectively and there was no significantly different in fall prevention behavior (t=-1.16, p=.25). Fear of falling according to the fall experience was significantly different by age (F=3.25, p<.05) and physical activity related to daily life (F=13.22, p<.001). Self-efficacy according to the fall experience was significantly different by age (F=3.03, p<.05), income per month (F=3.74, p<.05) and physical activity related to daily life (F=11.99, p<.001). But fall prevention behavior was no significantly different of general characteristics. Fear of falling according to the no fall experience was significantly different by age (F=3.37, p<.05), marriage status (F=3.37, p<.05), education level (F=5.15, p<.01), income per month (F=3.58, p<.05) and physical activity related to daily life (F=15.71, p<.001). Self-efficacy according to the no fall experience was significantly different by sex (t=2.32, p<.05), age (F=5.20, p<.01), marriage status (F=5.04, p<.01), education level (F=6.55, p<.001), income per month (F=5.99, p<.001) and physical activity related to daily life (F=18.86, p<.001). Fall prevention behavior was significantly different by marriage status (F=3.51, p<.05). Conclusion : The results of this study suggest the following : it is necessary to develop a program that can lower the fear of falling in the elderly and to increase the self-efficacy of falling, and to develop an education program that can improve the elderly's practice of fall prevention behavior regardless of the fall experience and to verify its effectiveness.

The two-dimensional motion of a freely falling circular cylinder in an infinite fluid is investigated numerically using combined formulation. The effect of vortex shedding on the motion of a freely falling cylinder is clearly seen: as the streamwise velocity of the cylinder increases due to gravity, the periodic vortex shedding induces a periodic motion of the cylinder. This motion in turn affects the flow field, which is manifested by the generation of the angular velocity vector of the cylinder parallel to the cross product of the gravitational acceleration vector and the transverse velocity vector of the cylinder. A correlation of St-Re relationship for a freely falling circular cylinder is drawn from the present results. The Strouhal number for a freely falling circular cylinder is found to be smaller than that for a fixed circular cylinder when the two Reynolds numbers based on the streamwise terminal velocity of a freely failing circular cylinder and the free stream velocity of a fixed one are the same. From "thought experiments", it is shown that the transverse motion of the cylinder plays a crucial role in reducing the Strouhal number and has an effect of reducing the Reynolds number from the viewpoint of the pressure coefficient. The mechanism of this reduction in the Strouhal number is revealed by the fact that the freely falling cylinder experiences a smaller lift force than the fixed one due to the transverse motion resulting in the retardation of the vortex shedding.

The purpose of this cross-sectional study was to explore fear of falling in relation to activity restriction of in the community dwelling elderly. Two hundred ninety-nine community dwelling elderly residing in Seoul and Kyonggi-do were interviewed using a structured questionnaire. The results were as follows : 1. Subjects were predominantly women$(70.6\%)$, an average 72.5 years old; the incidence of falls in last one year was $45.5\%$. 2. The highest level of fear found for activity in those who say they do engage and those who do not engage in the activity was 'going out when it is slippery '(m=2.53, 2.81) and 'reach for something over your head'(m=1.66, 2.60). Fear of falling scores were significant lower for those who say they do engage in eight kinds of activities (excluded activities of given were 'go to the store', 'take a tub bath', 'get out of bed') than for those who do not engage in the activities. 3. Among those who did not perform the activity, the three activities, when it is slippy(n=80), reaching overhead(n=70), and walk outside(n=59),were most often avoided because fear alone as well as for reasons in addition to fear. 4. The significant variables associated with fear of falling were female(p=0.0000), 1 educational status(p=0.000l), poor economic condition(p=0.0007), and experience of falls in last one year(p=0.0007). Fear of falling is common in the community dwelling elderly in Korea and is associated with several demographical variables. Therefore, to prevent falls and to reduce fear of falling, further study for development of education program for the elderly is needed.

Purpose: This study was designed to examine fear of falling, depression, physical fitness, and physical activity and further to identify the factors that predict physical activity among community dwelling elders. Methods: This study was a cross-sectional descriptive survey. Participants were 153 community dwelling elders from G city. Data were collected using structured questionnaires and were analyzed using descriptive statistics, ${\chi}^2$-test, t-test, ANOVA, and multinominal logistic regression analysis. Results: Activity levers were coded as inactive, minimal activity and enhancing physical active. Thirty-three point three percent reported inactivity, forty-seven point seven percent reported minimal activity and nineteen percent reported health enhancing physical activity. There were significant differences in physical activity relative to gender, age, falling experience, perceived health, and living situation. Further, there was significant difference in fear of falling, depression, and physical fitness by physical activity. For instance, Fear of falling (OR=1.04, p=.014) was a significant predicting factor for physical activity, In contrast for the enhancing physical active the variables of gender (OR=0.28, p=.046), age (OR=0.86, p=.021), perceived health (fair: OR=13.61, p=.006), fear of falling (OR=1.04, p=.026), and two-minute step (OR=1.04, p=.049) were significant. Conclusion: The results of this study indicate that physical activity intervention programs are needed to increase physical activity for community dwelling elders. Physical activity intervention programs should be developed and evaluated.
