This study is about the modeling of comfort feeling structure in indoor environments. To represent the degree of practical comfort feeling level in an environment, we measured elements of human sense and resultant elements of comfort feeling such as coziness, refreshment, and freshness with physical values(temperature, illumination, noise. etc.). The relationships of elements of human sense and elements of comfort feeling were formulated as a fuzzy model. And a hybrid-neural network with three layers were designed where obtained from fuzzy membership function values of the elements of human sense were used as inputs, and given as fuzzy membership function values of resultant elements of comfort feeling were used as outputs. Both kinds of fuzzy membership function values were obtained from physical values. The network was trained by measured data set. The proposed hybrid-neural network were tested and proposed a more realistic model of comfort feeling structure in indoor environments.

In this study, through the roadside interview, drivers'feeling about fatigue has been evaluated synthetically and systematically when they drive a vehicle according to their sex, vehicle type, driving career, etc. Also, with the human sensibility evaluation technique, we grasped the human sensibility structure for the fatigue in a vehicle and as an objective evaluation index for comfort and fatigue in a vehicle, we developed a sensibility database. Through the survey and research, extracting and understanding the importance of factors which have influence on the fatigue in driving can be used as basic data that can suggest more comfort and pleasant driving environment to drivers. Also, human sensibility database regarding to the comfort and fatigue in a vehicle can be used as basic data in ergonomic vehicle design, evaluation for seat , comfort seat development, development of vibration reduction method and so on.

This study surveys the thermal property and air permeability to the weight reduction rate of PET fabrics. For this purpose, 12 kinds of satin and 18 kinds of plain weave fabrics are prepared with change of the physical properties such as weft yarn count, t.p.m. and density. The weight reduction rate was 0%, 12%, 25% and 30%. The warm/cool feeling(Qmax), thermal insulating value(T.I.V.) and thermal conductivity(K) were measured by KES-F7 System and discussed in relation with the weight reduction rate, weft yarn linear density, t.p.m., weft density of fabric and weave structure.

Beauty of balance, can be found in antique furniture of the Joseon Dynasty. Balance, give comfort and peace of mind to people. Even today, the balance in various fields, it is easily viewed, and an important one element indispensable in the design. Various lighting is an essential element of the interior to create an atmosphere of space. It is also useful in a variety of ways for beauty, emotional effect, such as the switching of visual atmosphere. This design was designed with the concept of balanced. In addition, I have applied a simple graphic appearance. To give the fun and tension while giving it a well-balanced when you meet the figure. The design of this study is nothing more than a single direction. It will be in the traveling direction of the future as a designer by using a simple structure and phenomena that appear in life, is given to the design without the feeling of rejection to the user.

This study was conducted to investigate the relation between clothing pressure and subjective sensation exerted by foundation. Nineteen females volunteered as subjects. Experimental foundations were brassiere with 70B, 70C, 75B and 75C size which were widely distributed in pilot test and two types of girdle of which size were 64, 70 and 76. Clothing pressure with an air pack system and subjective sensation were measured at 5 points in brassiere and 7 points in the girdle. As the result of this study, brassiere's band and girdle's waist line, of which clothing pressure are high, is needed to improve. Generally the more pressure makes the more tightness, however, in some regions more or less pressure can give comfort. The tightness rating may not only related to clothing pressure, but also related to factors such as body size, body fat, resilience of muscle and bone structure. Other subjective sensation such as tactile feeling, hot/wet feeling, etc. in addition to the study with consideration of these factors could be used in future research to evaluate the effectiveness of foundation.

For modern people who spend most of their time indoors, the indoor environment is very important. The efficiency of work depends on the amenity level of the occupants who use the office space. Therefore, the experiment was conducted to derive the proper illuminance according to the amenity level of the occupants. The experiment was conducted in an office in Chilgok County for 6 days. The illuminance of the indoor was changed every day, the feeling brightness of the occupants was measured every 10 minutes, the eye fatigue was measured every 30 minutes, and the overall illuminance and the work surface illuminance were measured every hour. Experimental results show that the feeling brightness is different depending on the position of the occupants. Also, it was found that the brightness survey preferred by the occupants required more proper illuminance than the brightness. In addition, it is considered that there is a correlation with indoor temperature and humidity as the eye fatigue of occupants. Brightness preference by time of day was analysis from feeling brightness of occupants and preference brightness of occupants, and then it was analyzed like eye fatigue to derive proper illuminance per hour. Based on these results, it can be utilized for improvement of eye amenity existing office space.

The falling accidents have increased in the structure and heavy industries. Therefore, a various falling prevention systems with safety block and lanyard have been supplied in order to prevent falling accidents and acquire the long life and cost down for the maintenance. However, there are not the reliable and domestic the falling prevention system until now. Almost systems were imported from U.S.A, Japan, U.K and Germany. The structural safety of the imported safety block is satisfied sufficiently, but it has heavy weight due to the cover with the aluminum and thickness. So, many workers are not feeling themselves. Thus, the aim of this work is to develop a commercial safety block that has a light weight and strength. And the cost efficiency of the system and safety for workers also will be improved remarkably.

인간이 쾌적하다고 느끼게 되는 것에는 인간과 환경간의 상호작용이 포함되어 있다. 쾌적한 환경을 만든다고 할 때에는 인간과 환경을 하나의 시스템으로 두고 관련되는 여러 요소들이 계속적으로 피이드백 되는 것으로 생각하여야 한다. 쾌적감이란 여러 가지 감성 요소가 복합적으로 조합되어 하나의 이미지와 합치되는 것으로 표현되는 고도의 심리적인 체험감이다. 그러므로 쾌적환경에 대하여 인간의 특성을 중심으로 설계하려고 하면 인간이 쾌적환경을 인지하는 과정이 어떤 과정을 거치게 되는가를 알고 그 특성을 고려하여야 한다. 본 연구는 쾌적감을 구성하고 있는 요소이미지가 어떻게 구성되어 있으며, 환경요소에 대한 감각이미지와는 어떤 구조로서 이루어져 있는 지를 실험적으로 알아보고 퍼지 추론을 이용하여 표현하였다.

This study conducted a survey to find out atopic dermatitis patients' required performance and preference in design factors to develop spring/summer(S/S) knitwears preferred by atopic patients. On the platform of achieved information from statistical analysis, S/S knitwear samples for atopic patients were designed and constructed with cotton/Seacell(R) blended yarn, And subjective wearing sensation were evaluated comparing the samples and the commercial products made with cotton/chitosan blended yarn, trying to help producing more comfortable S/S knitwears for atopic patients. SPSS 12.0 program was used for frequency analysis, Chi-square analysis, ANOVA, and Duncan test. The result was as follows; For comfort of S/S knitwears, atopic patients most considered skin care property. Atopic patients preferred simple and basic knitwear in light color with thin and soft fabric such as plain knit. The preferred style was that 'appropriately fit with suitable ease'. They also preferred 'closed front'; 'boat neckline' and 'V neckline'; 'raglan sleeve' and 'set-in sleeve'. For hem trim, they preferred 'rib' structure. Male preferred simple and plain style with 'round collar' and 'tubular or rib trim", while female preferred sophisticated and characteristic style with 'set-in sleeve' with 'rib trim'. Under the circumstances with insufficient functional knitwears developed, this study tried to develop comfort S/S knitwears for atopic dermatitis patients and the developed knitwears showed as good as or better performance in wearing feeling, fitting, and appearance than the previously developed functional goods.
