In the current residential building, hot water supply system consumes the second largest energy in order to make the thermal comport condition of residential space. The more residential environment improves the more the demand for hot water and water consumption is increasing gradually. So this study examines the possibility of applying the recirculation for individual hot water supply system compared with the existing method for waiting time for hot water, wasted water and energy consumption. The results are as follows. (1) In case of recirculation system method the waiting time for hot water can be reduced up to $69\sim85%$ in spring and fall period and so dose up to $77\sim85%$ in winter period. (2) The total wasted water has a little change compared with the existing method which can make the total wasted water reduced about $77\sim86%$. (3) The efficiency of hot water supply system can be improved, if the method which blocks the inflow of cold water is applied, when return pump is operated to recirculate hot water in recirculation system.

In general, deflection limit criteria of bridge design specifications have been considered based on static serviceability and structural stability. Dynamic serviceability induced from bridge vibration actually has not been included in the criteria. Thus, it is necessary for comfort limit to be considered in order to check dynamic serviceability on bridge vibration. In this study, the comfort limit of bridge structures based on the RMQ and VDV considering the signal fluctuation effectively and the time duration exposed has been constructed. The comfort limit developed in time domain was verified by using vibration signals directly measured from the existing bridges. Comparing the developed comfort limit with the conventional ones defined in frequency domain, it is shown that the comfort limit developed in time domain would be more feasible for evaluating quantitatively the serviceability due to bridge vibration. Using the Bridge-train interaction analysis program, dynamic response of the bridge by the stiffness change were obtained for several railway bridges. And, a stiffness limit satisfying the bridge vibration serviceability was estimated by compared with comport limit. From the results, a new deflection limit on bridge structures satisfying the vibration serviceability could be proposed by comparing with the conventional deflection limit criteria.

The purposes of this study were to segment male university students on the basis of benefit sought in clothing, and to investigate knitwear image preference and purchasing behaviors of each segmented market. The research method was a survey and subjects were 249 male university students in Daejeon and Chungnam province. The questionnaire consisted of measurement items for benefit sought in clothing, knitwear image preference, knitwear purchasing behaviors, and subject's demographic attributions. The data were analyzed by Cronbach's ${\alpha}$, factor analysis, cluster analysis, ${\chi}^2$ test, ANOVA and Scheffe test. The results were as follows. First, male university students were segmented into 6 consumer types (practicality pursuit, individuality pursuit, comport pursuit, brand pursuit, social status pursuit, and unconcern type) by benefit sought in clothing. Second, male university students generally preferred dandy image and causal image, however, brand pursuit type more preferred trendy image, and practicality pursuit type more preferred active image than other consumer types. Third, the segmented markets showed many differences on knitwear purchasing behaviors. On clothing selection criteria, practicality pursuit type considered resonable price as important, whereas brand pursuit type considered brand reputation. On fashion information source, individuality pursuit type considered store display and other people's clothing, while unconcern type considered advice from friend and family. On main purchasing place, individuality pursuit type more used speciality store with no brand, whereas brand pursuit type more used department store and brand store than other consumer types. The results of this study supported that benefit sought in clothing can be useful as an effective variable for market segmentation.

Recently, the spatial design of resting spaces in department stores has been changed. The design elements such as colors, materials, lighting, natural elements, furniture arrangement, and VMD are not only providing a pleasant and natural indoor atmosphere in resting spaces but also providing various services to customers. In this study, it aims to analyze how the spatial design characteristics of resting spaces in department stores are appeared. The results are as follows. First, the spatial characteristics of the resting spaces in department sores came up as five factors; accessibility, recognition, comfort, convenience, and esthetics. As the result, the accessibility is the most important factor in resting spaces. Second, the resting spaces was well located near by the elevators and escalators providing easy accessibility to customers to floor. Third, the resting spaces need to improve the spatial design for emphasizing the recognitions by using colors, materials and lighting. Fourth, the resting spaces were provided different atmosphere by their location. Fifth, the various forms of furniture, curved, zigzagged, and cubed, were placed in the resting spaces for comport use. Sixth, the aesthetic was the least important factor of all. To improve this problem, the resting spaces need to provide cultural contents by installing art pieces, moving picture facilities, and VMD. Seven, most of the resting spaces had similar floor plan type that they did not perform their role successfully. The resting spaces need to provide both individual rooms and unique open spaces for giving a choice to use when customers visit them.

한일 위안부 합의 이후 관객들의 관심 속에 소개된 두 편의 영화 <귀향>과 <눈길>은 모두 '위안부' 소녀들의 우정을 다루면서 살아 돌아 온자가 살아 돌아오지 못한 자를 고향과 저승으로 보내는 해원의 이야기를 다루었다. 기존의 '위안부' 서사들과는 다르게, 이 두 영화는 '위안부' 여성의 전장에서의 로맨스 플롯을 가지고 있지 않으며, 일종의 여성공간을 구축하고 있다. 현실에서의 새로운 젊은 여성의 존재는 개인적 우정의 이야기를 자매애의 공동체 차원으로 확장시킨다. 특히 <눈길>은 '위안부' 할머니가 새로운 후속 세대 여성에게 증언을 전수하는 증언작업의 가능성을 제시하고 있다. 영화적 현재에서는, 이렇듯 일본군 '위안부' 서사를 여성주의적으로 사고할 수 있는 가능성을 보여주고 있지만, 과거 식민지 시절의 재현은 많은 부분 기존의 가부장제적인 민족주의적 관점을 벗어나고 있지 못하다. 주인공들이 여전히 '순수하고 순결한' 조선소녀들로 설정되어 있다는 것이 대표적이다.

In this study the physiological significance of the upper and lower body on thermoregulation and sensation are examined. Experiments were carried out on 4 females in a climatic chamber conditioned at $25\pm1^{circ}C, 50\pm5%$ R.H.. Before the measurements, subjects were exposed to 3 types of enviromental temperature: 1) $25\pm1^{\circ}C$ for 60 min.(ST), 2) $25^{\circ}C$\rightarrow35^{circ}C\rightarrow25^{\circ}C$ for about 40 min.(HT), 3) $25^{\circ}C$\rightarrow15^{circ}C\rightarrow25^{\circ}C$ for about 40 min.(LT) covering the upper body (U) or lower body (L) with garments. 1) $T_{re}$ was significantly higher in L than in U only in 57 condition. $T_{sk}$ and Temp. under the clothing were higher in U than in L in all three conditions. Thermal sensation was warmer in U than in L, and comport sensation was most comfortable in HT condition. 2) When the upper or lower body was covered or exposed, the mean skin temperature of the upper body was higher than that of the lower body. Following covering and uncovering the same area, the changes in skin temperature were greater in the upper body than in lower body, and covering the upper body produced a greater difference of skin temperature between body and lower body than covering the lower body. 3) In all environmental conditions, when the upper body was uncovered, the skin temperatures of the chest, upper arms and forearms dropped to a considerable degree, and when the lower body was uncovered, skin temperatures of the legs showed the same pattern. On the other hand, skin temperature of the thinghs showed only little change in all cases except forehead and back uncovered or covered in two clothing types.

In this paper, the results of evaluating the passenger comfort due to the standard deviation of acceleration in vertical and lateral direction regarding the ship response in irregular wave by ordinary strip method in regular wave and energy spectrum using linear superposition theory in order to evaluate the motion of experimental ship are as follows. According to the results of ship response, it was possible to find that, in order to reduce the motion of ship, a ship operating in bow sea was more stable than in quartering sea. In the results of analyzing the standard deviation of acceleration in vertical direction according to each component wave pattern, when there was a wave length of 56m and an average wave period of 6 sec, most of cases showed the peak value. And among them, the standard deviation was 0.35 which was the highest in head sea. And in case of lateral direction, the maximum value was shown in a wave length of 100m and an average wave period of 8 sec. And it was 0.16 in beam sea and ${\chi}=150^{\circ}$. In the evaluation of passenger comfort due to standard acceleration in vertical and lateral direction, it was 80% in head and bow sea. On the other hand, it was shown to be 15% in follow sea. Accordingly, when the expected wave height in a sea area where a training ship was intended to operate was known, it was possible to predict the routing of ship. And altering her course could reduce the passenger comfort by approximately 50%.

The purpose of this study was to compare the comfort sensation depending on four different kinds of denim blue jeans: cotton, cotton/tencel, tencel, cotton/pp. The objective and subjective experiments were conducted to measure the comfort of blue jeans. To investigate the objective comfort, physical properties related to thermal insulation, moisture properties and hand were measured. For subjective comfort measurement, 5 healthy female college students were taken as subjects. The outcomes of the experiments are as follows: The higher the air permeability and bulk density of the denim, the lower the thermal insulation, the thicker the denim, the higher the thermal insulation. Tencel blending denim showed the higher bulk density, the lower air contents, and consequently the lower thermal insulation than the other denims. Tencel showed the highest moisture regain, and cotton/tencel blend showed the highest water vapor permeability. Tencel denim had relatively better flexibility, shape stability and elastic recovery than the other denims. The total hand values of the denims by KES-FB system were not significantly different. Cotton and cotton/pp denims raised the subjects body temperature after excercise more than tencel or cotton/tencel denims. Average skin temperature was found to have a correlation with micro climate temperature and micro climate humidity. The correlation coefficients were 0.749 and 0.767, respectively. However, average skin temperatures were not significantly different among the materials. Pulse rate was found to be the highest when wearing cotton/pp and the lowest in case of cotton/tencel denim. The energy was consumed in order of cotton>cotton/pp>tencel>cotton/tencel. There was no significant difference in preference before excercise, but, after the excercise, the order of preference changed as the following; cotton/tencel>tencel>cotton/pp>cotton.
