Purpose : The solar shading device carries out roles in a reduction of the cooling load and an improvement of the thermal comfort of occupants by adjusting incident solar radiation. In addition, The shading device enhances the visual sensation comfort by controlling the optical properties. In order to improve building performance and comfort of occupancy, interests in application of the shading devices are getting increasing. This study investigated the application and effectiveness of the external shading device design using statistical analysis. The outcome of this paper could be utilized for the realization of status quo and for an estimation of effectiveness of the shading device Method : The period of data gathering was between 2003 and 2014 and total 459 cases of practical building project were investigated. Firstly, this study defined qualification of the shading devices; the shading device should have minimum protruding lengths of 150mm to outside and have the function of shading control. This paper investigated application rate of the shading device in real project, regional rate of application, annual change of application, materials and types. Result : The statistical analysis showed that the application rate of shading devices was 25.7% in total 459 building design projects. The application rate in central and southern region was 25.3% and 27.0% respectively. Meanwhile, Jeju region showed 22.2%, which was the lowest rate although this area needs more shading devices. The application number of the shading device was the smallest in 2007, but the rate gradually increased after that. The applications was the largest in 2014 due to growing interest of the shading devices in the building.
The purpose of this study is to analyze the expression method according to the planning of townhouse and the healing method that affects residents for communicating with natural environment, in order to propose resident-focused communication with nature for healing. The results are as follows. First, the expression of nature elements can be divided into 'direct' and 'indirect' and healing effects through nature can be divided into 'body' and 'psychology'. The healing method of residents through nature was classified into physical and psychological healing through openness, familiarity, comfort, and stability. Second, as an expression method according to townhouse planning, the arrangement plan induced active communication with nature through the arrangement according to topography and a common garden. In terms of construction plan, a bigger window or door than that of other residential spaces was installed on a wall, ceiling or opening to directly bring the nature of outside visually for more communication. Third, with regard to healing methods of townhouse, 'openness' which reduces depression and increases self-esteem, expands the view of residents. 'Familiarity', the healing method that can relieve the fatigue of eyes and bring psychological warmth and comfort, makes us feel familiar through the pattern and texture of woods and stones that are natural materials. 'Comfort' which heals residents by creating an outside space and bringing the nature elements through a huge window can provide psychological healing such as eased tension in daily life as well as physical healing such as vitamin D synthesis and the recovery of physiological function. Also, 'Stability' gives a comfortable feeling by applying the colors of finishing materials inside or seeing the colors of surrounding nature as it is through big windows. Finally, in order to support the results of this study more objectively, a follow-up study conducting a survey on the residents of townhouse is needed.

The assessment of wind-induced motion plays an important role in the development and design of the majority of today's structures that push the limits of engineering knowledge. A vital part of the design is the prediction of wind-induced tall building motion and the assessment of its effects on occupant comfort. Little of the research that has led to the development of the various international standards for occupant comfort criteria have considered the effects of the low-frequency motion on task performance and interference with building occupants' daily activities. It has only recently become more widely recognized that it is no longer reasonable to assume that the level of motion that a tall building undergoes in a windstorm will fall below an occupants' level of perception and little is known about how this motion perception could also impact on task performance. Experimental research was conducted to evaluate the performance of individuals engaged in a manual tracking task while subjected to low level vibration in the frequency range of 0.125 Hz-0.50 Hz. The investigations were carried out under narrow-band random vibration with accelerations ranging from 2 milli-g to 30 milli-g (where 1 milli-g = 0.0098 $m/s^2$) and included a control condition. The frequencies and accelerations simulated are representative of the level of motion expected to occur in a tall building (heights in the range of 100 m -350 m) once every few months to once every few years. Performance of the test subjects with and without vibration was determined for 15 separate test conditions and evaluated in terms of time taken to complete a task and accuracy per trial. Overall, the performance under the vibration conditions did not vary significantly from that of the control condition, nor was there a statistically significant degradation or improvement trend in performance ability as a function of increasing frequency or acceleration.
This study identified design elements of the functions required for children's ski pants. Data for this study were collected through questionnaire surveys conducted among children's ski instructors and children's sportswear developers. Five functionalities of children's skiwear were evaluated: mobility, stability, comfort, protection, and convenience. A total of 25 functional design elements related to the patterns, design details, and physical characteristics of fabrics for ski garments, were evaluated. The results of this study are as follows. First, children's sportswear developers evaluated that the pattern elements were important. Most of the pattern design elements highly related to mobility. Children's ski instructors' appraisal was that the height of the back waist was the important feature. Second, regarding the design details, children's ski instructors evaluated the size adjustment function and ventilation system as important elements. Many design detail elements were highly related in respect of stability, comfort, protection, and convenience. Third, the physical characteristics of fabric were strongly associated with mobility, comfort, and protection. As regards the physical characteristics of fabric, children's ski instructors valued anti-fouling highly, but children's sportswear developers attached more importance to the weight of the fabric. The results of this study will be useful in designing functional ski pants for children of elementary and intermediate ski levels. Since there may be limitations related to the ski level and age of children wearing ski pants, it is suggested that follow-up studies according to various groups of the ski pant wearers should be done.
The objective of this study was to determine the optimal angle of a wind louver that would induce the optimal wind speed for indoor. Being controlled to have an optimized angle depending on the direction from which wind is blowing and the wind speed, the wind louver to be installed on the building envelop comes to create indoor comfort through a constant wind speed using the function that reduces the indoor wind speed by changing the angle when the wind speed is not lower than a certain level and makes wind flow into the room to the maximum when the wind direction is adverse to catching the wind or the wind speed is not higher than a certain level. To determine the optimal wind louver angle, a core-centered office building with cross-ventilation problems in the climate of Seoul, Korea, which experiences four distinct seasons, was considered for analysis in this study. A module 1 office space model was used for the CFD simulation to analyze the average indoor wind speed with respect to the outdoor wind speed (varied between 1 and 8 m/s), the wind louver angle, and the outdoor wind direction (varied between $0^{\circ}$ and $180^{\circ}$ in steps of $10^{\circ}$).
This study was performed to find ways to improve the wearing comfort of high school boys' summer uniforms. The subjects were 640 boy students of high schools in Cheongju and Ansung city. The data was collected self-administered questionnaires to measure the actual wearing condition and the wearing satisfaction. Factor analysis, t-test, and F-test were used for data analysis. The results were as fellows: 1) Most students were wearing shirts made of polyester/rayon blended fabrics and pants made of wool/polyester blended fabrics. 2) Most students were wearing round neckline T-shirts or running shirts as underwears of the shirts, and trunks as pants. 3) About a half of respondents had altered their summer uniforms, and main alteration of their uniforms was focused on making their pants narrow. 4) The wearing satisfaction of uniforms were classifies into three factors: aesthetic, moving function, thermal comfort wearing sensation. 5) They evaluated the wearing sensation of school uniforms of shirts and pants with low satisfaction. 6) There were partially significant differences in three factors of the wearing satisfaction according to the uniform's fabrics, the wearing of underwear and the alteration of uniform.

This study aims to find equivalent comfort contours, reciprocal of frequency weighting curves, for vertical steering wheel vibration. Psychophysical responses were measured from twelve male subjects by using magnitude estimation of relative discomfort due to vertical steering wheel vibrations of magnitude of 0.1 to 1.58 $m/s^2$ in the frequency range of 4 to 250 Hz. Relative discomfort were estimated with a reference vibration of 0.4 $m/s^2$ at 31.5 Hz. Equivalent comfort contours were produced from the median of sensation magnitudes judged by twelve subjects, which showed variation in the shapes with increase of vibration magnitude. A shape of the contour came close to the perception threshold curve with decrease of vibration magnitude. When the vibration magnitude increases, the shape changed close to those in the references of Hong and et al (2003). It is also recommended frequency weighting curves for vertical steering wheel vibration must be expressed as a function of vibration magnitude as well as frequency.
To develop the work clothes for the employees in the mechatronics industry in South Korea, a questionnaire survey on many aspects of the work clothes such as type, color, detailed design and function preference of the subject employees has been carried out in the study. The results throughout the survey highlighted certain functions such as extensibility, thermal and air permeability of importance for the work clothing performance. To improve the discomfort caused by some work motions (i.e. squatting down, ascending/descending the stairs, raising arms), more allowances were given to the measurements (i.e. body rise + 2cm and crotch depth + 1cm for squatting down pose; thigh circumference + 1cm and knee circumference + 1cm for ascending/ descending the stairs pose; chest circumference + 5~6cm and jumper length to the level of hip circumference line for raising arms pose) for work clothes patternmaking. The evaluation of the two types of spring/summer and winter work clothes' clothing comfort and wearer mobility suggested certain points to improve the clothing performance (e.g. ventilation slits on the back pleats, arm pits and collar band of the spring/summer suit using net material and lining for the winter suit using quilted thermal materials) and wearer mobility (e.g. pants hem buckles for the easy work motion), which also enabled to fulfill the workers' work clothes design preference.
The purpose of this study is to investigate the actual conditions of clothing of disabled adult men using wheelchair, to understand dissatisfactions and problems in wearing garment, and to construct basic data to development of the formal wear for wheelchair user. This study conducted survey of 162 men using wheelchair who regularly enjoy the sports for disabled people or who work in society. The results of this study are follows. The majority of wheelchair user tend to wear garment lying or seating. Therefore, they prefer garments that can be easily put on and off. They were dissatisfied mostly with the size of ready-made garment. More than 75% of the subjects tend to repair the purchased formal wear. Shoulder width and bust circumference are too small, jacket length, sleeve length, and slacks length are too big for disabled men using wheelchair. More than 93% subjects tend to prefer T-shirts, because of comfort and easiness to move. The men using wheelchair consider the function and the hygiene of fabric material for T-shirts as the important end.
This study intended to survey whether or not hotel employees were satisfied with their uniforms. Through this study we hoped that the study will bring about improvement in hotel employees'uniforms. We also hope to offer desirable alternatives if dissatisfaction is shown. The study results are as following: 1. 59.2% of employees indicated that they were comfortable and felt a sense of belonging when wearing their uniforms. 2. 46.1% of employees asked, stated that their uniform identified which hotel they were employed at. 59.2% of employees gave average credit that the uniforms which they were shown the various positions held within at a hotel. 3. Woman believed more strongly than men that their uniforms distinguish them from other hotels. Older people were more positive about it than younger people were. 4. 55.3% of employees felt that improvement in uniforms was necessary. 22.4% of employees were satisfied with the uniform they wear, therefore generally the level of dissatisfaction is quite high. 5. 59.2% of the survey showed that they have to improve the design of uniform they wear and 25% showed the function of the uniform needed improvement also. 6. 50% of employees believed that color and design is mediocre. 46.7% complained of bad sweat absorption. 7. Preference in uniform are follows: 78.9% prefer comfort. 63.2% prefer a more fashionable design and also different colors in uniform in different departments. 8. This study shows that employees in the hotel industry would like to consider in the following order comfort (76.3%), design, color, and cost to be taken into account when uniforms are made.
