The purpose of this study is to examine how the floor heating system is affecting to users in childeren's libraries. This study included the method that extracts the affordance of the floor heating system, after surveyed using behavior in children's libraries and referred to J. J. Gibson's affordance and surface concepts. As the positive affordance, it was grasped that the floor heating system promotes social relationships and affords various surfaces for library using, but also as the negative affordance, that hinders users in the public usings and the behaviors for reference and using. The behaviors of these various characters can be regarded as life behaviors resulted from the sitting life style and the natural using behavior can give to children emotional rest and autonomous reading experience. For the function as the children's library, the learning of sociality in the public building and the various reading space, the space planning of children's library should be done after the positive and negative affordances extracted from this study are reflected. The guidelines for space planning are summarized as the followings: the layout of book furniture, the shoe chest and the space around that, the furniture hight and children's eye level, and the practical using of the table for sitting life style.

In order to flatter the figures of average middle aged women by determining harmonious proportions for their costume forms, this study evaluates effects of varying design details of jackets(coats) with blouses and slacks using a ranking test and paired comparisons test. The result from clothing design C-2 which has the best design effect were as follows; 1. In order to look taller, the jacket(coats) is divided vertical long line and it has the emphasis point close to the face. 2. In order to make shoulder width look wider, armhole seam line attached 1-2 cm from the shoulder point. 3. In order to make chest width look slimmer, division was made up of a tailored collar with a deep V-neckline. 4. In order to make waist circumference look slimmer, the jacket has more fitted waist line than loosed it and tailored collar with a deep V-neckline. 5. In the case of the division of upper and lower garments, when the division was closer to the golden section, i.e., when the jacket hemline is hipline and slacks length is the heel excluded length of shoe heels, the overall appearance was better. 6. The V-neckline looked better, when it was cut along a long acute angle to the waist line. Because of dividing along above factors 1-6 i.e., clothing design C-2 was overall harmonious. Appropriate division of costume forms made for an aesthetic composition, which flattered the body types of middle aged women and presented harmonious, beautiful costume design effects. It made the women look taller, slim and balanced, and highlighted middle aged women's sense of beauty.

The damage caused by lateral movement occurs frequently on site where abutment or retaining wall was built on soft ground along with embankment behind and the study on stability of abutment against lateral movement has been mostly focused on soft ground. However lateral movement occurs not only on soft ground but also on embankment slope which causes the impact on structure. The bridges built in Korea are mostly on mountainous area than soft ground. This study is intended to analyze the ground behavior resulting from lateral movement using finite element analysis method to the section as well as propose the basic data for abutment design on embankment slope through the analysis of the outcome of reinforcement method. As a result, when it comes to the reinforcement with soil surcharge and stabilized pile in slope, lateral movement was reduced by 4~30% and displacement on bearing shoe on abutment was reduced by 2~13%. On the contrary, when reinforced with EPS, lateral float was reduced by 97% and maximum horizontal displacement of bearing shoe on abutment was reduced by 95%. Thus, it's necessary to identify the design technique which is applicable to domestic condition through additional tests and more reliable study using numerical analysis and comparing the measured values shall follow.

Objective: The aim of this study was to analyze effects of the toe-spring angle of bobsleigh shoes on start speed lap time to develop Korean-specific bobsled shoes suitable for winter environments and for domestic players on the basis of sports science and optimized biomechanical performance. Method: Seven Korean bobsleigh athletes participated in this study, with three pairs of sprint spikes from three companies (Type A, Type B, Type C). To analyze sprint lap time and forefoot bending angle for each shoe, participants were instructed to drag a sled 15 meters from the start line at a maximum sprint. forefoot bending angle was collected by a high speed camera, and lap time speed was measured. Results: Lap time for type B shoes was $3.52{\pm}0.17sec$, type A was $3.55{\pm}0.19sec$, and type C was $3.56{\pm}0.18sec$. Forefoot bending angles were: angle 1, $6.88{\pm}5.55^{\circ}$; angle 2, $9.23{\pm}6.38^{\circ}$; angle 3, $15.56{\pm}5.39^{\circ}$; angle 4, $9.54{\pm}3.85^{\circ}$; angle 5, $9.22{\pm}5.08^{\circ}$; angle 6, $7.66{\pm}6.44^{\circ}$; and angle 7, $4.30{\pm}6.24^{\circ}$ (p<.001). Forefoot bending in angle 3 was as follows: type A, $16.47{\pm}6.01^{\circ}$; type B, $14.30{\pm}4.96^{\circ}$; and type C, $15.90{\pm}5.17^{\circ}$. Conclusion: Hard outsoles and midsoles are better than soft type for reduced start lap time when developing a prototype Korean bobsled shoe.

In this paper, we propose a stress analysis on foot by lifting task attitudes. Maximum force and peak pressure were measured on 8 body regions by Pedar system in order to analysis the stress which is affected by task style and angle on foot when Manual Materials Handling task. As for the peak pressure of the whole foot as to the task height during the lifting task, the height from Knuckle to Shoulder was the least in the peak pressure. Also, as for the maximum force and the peak pressure of the whole foot as to the task angle during the lifting task, it could be seen that the more an angle increases, the stress influencing on a foot jumps. As for the maximum force and the peak pressure by foot region as to the task height in case of the lifting task, the height from Knuckle to Shoulder is indicated the smallest value in the maximum force and the peak pressure, thus there is necessary to attain the work design that considered this. Also, as for the maximum force by foot region as to the task angle in case of the lifting task, 0° tasking is indicated to be least, thus there is necessity to be attained the tasking design in a bid to prevent the existence of an angle. The results of this paper are thought to be helpful to the suitable work design, to the prevention of musculoskeletal disorders related to the lower limbs, and to the design of ergonomic safety shoes.

This research is about shared living facilities for the solitary elderly in Gyeonggi province (so called "Carnation House"), which was opened after 2013. These facilities aim to help solving the social problems of the growing number of the solitary elderly. The research was conducted from April 2014 to October 2014 by using observation, measurement, photography, and interview methods. This research reviewed floor plan, area, accessibility, visual openness, and furniture and equipments. The results are as follows: First, considering the need for rest area and the protection of privacy, livingroom should at least be equipped with a variable wall or have a separate room. Secondly, for the kitchen plan, considering the fact that large number of people move simultaneously, kitchen entrance should be widened or LDK type is preferable. Thirdly, the bathroom entrance should be widened to at least 800mm and should have barrier free design. Fourthly, porch entrance should be planned to secure enough space and shoe cabinets for multiple users. Fifthly, to allow the users to enjoy outside view, the windows of living spaces should be placed no higher than 800mm from the floor level. Finally, for the location of the facility, people prefer the location be at the center of the village or near home. In addition, location with easy accessibility for the elderly is advisable. Therefore, establishing local guidelines for shared living facilities for the solitary elderly is advisable. When establishing local guidelines, local characters, culture and usage patterns should be considered.

Senior centers in apartment complex have been provided since 1980 according to the Housing Act in Korea. Nowadays these senior centers are model leisure facility for the elderly. However there are no specific guidelines for space composition and usage in a senior center. This study examines the space composition and usage patterns of 16 senior centers in apartment complex, Jangyou New Town. The data were collected by means of an observation, measuring, and interviews. The results are ; 1) A senior center consisted of one living room and two rooms for men and women would be appropriate; A living room is for common activities and two rooms for casual resting of each gender. 2) A kitchen is mainly used for setting the table or making tea. Thus, the living-dining-kitchen type would be appropriate. 3) Many rest rooms are located outside of a senior center and unisex one. The restroom should be separated by gender and located within the senior center. Also, the width of all doors should be more than 80cm and the floor be flat. The grab bars should be installed near the fixtures in a restroom. 4) Design and location of the shoe shelf are not convenient for the elderly to use. It should be designed and arranged for the elderly to use conveniently. Also, space for canes, walkers or wheelchairs should be considered in entrance area.

One of the most important design concerns for undersea tunnels is to establish design water load and flow rate. These are greatly dependent on the hydraulic factors such as water head, cover depth, hydraulic boundary conditions. In this paper, the influence of the hydraulic design factors on the ground loading and the inflow rate was investigated using the coupled finite element method. A horse shoe-shaped tunnel constructed 30 m below sea bottom was adopted to evaluate the water head effect considering various water depth for varying hydraulic conditions and relative permeability between lining and ground. The effect of cover depth was analysed for varying cover depth with the water depth of 60 m. The results were considered in terms of pore water pressure, ground loading and flow rate. Ground loading increases with an increase in water head and cover depth without depending on hydraulic boundary conditions. This points out that in leaking tunnels an increase in water depth increases seepage force which consequently increases ground loading. Furthermore, it is identified that an increase in water head and cover depth increases the rate of inflow and a decrease in the permeability ratio reduces the rate of inflow considerably.

This study aims to compare the beauty of costume in the Gothic with that of Renaissance periods. By analyzing the beauty of costume which reflects the ideal of the age, this study attempts to provide the insight which can predict the beauty of future costume The characteristics of Gothic costume is the from of the loose enveloping of the body, which can be accounted for from the influence the Christian religion, and the emphasis on the vertical line influenced by the steeple in the Gothic architecture expressing the enthusiasm of the religion. The emphasis on height in the Gothic cathedrals was reflected in the hennin, pointed shoes, and lengthy sleeves of Gothic dress. The beauty of Gothic costume lies in the from of slender, the emphases on the vertical line, the we of heraldry and parti-color, and pointed hat and shoe. The Renaissance architecture shows a broad horizontal appearance. There is the similarity between the Renaissance costume and Renaissance architecture. The beauty of Renaissance costume lies in the form of the exposing body, the exaggerated silhouette, the emphasis on the horizontal line, the use of ruff and slash in order to display the beauty of human body and the beauty of cubic. The ideal beauty of Gothic and Renaissance costume was influenced by the spirit the age and was in contrast.

The objectives of this study were to investigate whether heel height changes in the U.S. market occur in a cyclical pattern and heel heights show greater within-year variability over time. Heel height data from U.S. Vogue's spring and fall editions were analyzed over the time period 1950~2014. A total of 1581 pieces of data were measured in millimeter units using Adobe Illustrator and standardized by dividing the height of the heel by the shoe length through the curved sole line. To analyze the cycle pattern of heel heights, the yearly averages were standardized by using three-year moving average technique to average out the irregular components of time series data and give a better indication of the long-term fluctuation of heel height. To identify the degree of within-year variability of heel height, the standard deviation of the average measurements for a year was calculated, and then decade averages were drawn from the yearly averaged standard deviation. One-way ANOVA was conducted to compare the within-year variability of data in heel height over the time period studied by decade. The results showed: First, there was a trend toward higher heels from the early 1950s to 2011. Second, four cyclical movements of heel height were observed from 1950 to 2007, and heel heights gradually decreased after 2008. Third, the within-year variability significantly increased over time, especially after the 1980s.
