This study aims to develop workwear prototypes by applying a systematic approach considering the characteristics of workwear. A case study was conducted before this study to derive workwear's four characteristics: 'Ergonomic Pattern-Making, Certified Fabric, Specialized Color, and Customized Details.' a prior study proposed the integrated framework combining these characteristics with the FEA model. The new framework identified that these characteristics are considered in terms of functionality, expression, and aesthetics; it can increase workers' satisfaction and meet the market demand without concentrating on only particular aspects. Before prototype production, the requirements for each characteristic of workwear were analyzed through theoretical research of previously published related papers. The study primarily gathered workwear requirements data and sources from consumer satisfaction surveys and investigations into the wearing conditions of work clothes. When considering all aspects of pattern-making, fabric, color, and detail in functionality, 'comfort movement, body protection, improved work efficiency' were identified as necessary. Expressive requirements were fundamental, including 'reflecting the wearer's preferences, expressing a sense of belonging and identity. It was clear that incorporating design elements and applying current trends to the aesthetic requirements of work clothes was necessary. Four prototypes comprised two top and bottom sets and two overalls using these requirements. The framework was used throughout the entire process of planning, producing, and evaluating prototypes, and through this, the results fulfilled the requirements. This study is significant because it produced workwear prototypes using an integrated approach that considered functional, expressive, and aesthetic aspects.

This study investigates thermoregulatory behaviors of obese children for their thermal comfort. Nine normal-weight children (NWC) and nine obese children (OC) participated in the study. All subjects were fourth-graders and sixth-graders in elementary school. An informed consent form was obtained from each child and his or her mother. The questionnaire method was used, and the experiment was conducted to determine the preferred amount of clothing at $17^{\circ}C$ and the preferred temperature at $33^{\circ}C$. According to the results, OC were more susceptible to heat than NWC, whereas there was no significant difference in their susceptibility to cold. There were no significant differences of the oral temperature and the mean skin temperature between the two groups, but changes in forearm blood flow were less in OC than in NWC. There was no significant difference in the preferred amount of clothing between OC and NWC, and the preferred temperature was higher in NWC than in OC. The results based on the questionnaire are consistent with those based on the experiment. A compositive study of physical exercise, eating behavior, and wearing behavior should be useful for developing programs for preventing and treating obese children.

In creating an avatar, consumers can find out for themselves their own sizes to be entered. Also, putting in a face creation main-page menu option enables clients to make up their faces and match them to their bodies. Through this process when purchasing clothes through the internet consumers can enter their own body sizes and create avatars that are identical to their body shape. The uniqueness of developed prototype is that it creates an avatar similar to one's body shape according to body size inputs and demonstrates visually to customers the on-line comfort test which was only available off-line traditionally. The avatar follows the movement of mouse from left to right which enables 3 dimensional visualization. Through maximizing the visual effect this research focuses on enabling consumers to feel subjective parts as if they are off-line. This study seeks to provide a type of prototype of an online shopping mall that meets the demand of the consumers using the 3D avatar.

This article is a continuing report about a development of disposable diapers for the elderly in need. In previous report, the first prototypes of disposable diapers in two different categories have been developed. One was a panty type and the other was a pad type. These prototypes were results of property test and wear test of existing disposable diapers in each categories. Yet, in order to develop useable products, the second property and wear tests using the first prototype diapers were carried out. Considering the resets of the second tests, enhancements to the first prototypes were made to refine the second prototypes. The panty type diaper were altered to be longer to prevent evacuation from leaking and fit better. The pad type diapers were altered to reduce thickness for comfort and wearing appearance when get dressed. Ultimately a lot more disposable diapers will be required in future. Resulting suggestions are as follows. Anthropometric data around hip area of elderly in both sexes have to be collected to give meaningful information to diaper manufacturers, so that they can manufacture for different sizes and different sexes. Also we suggests that diapers for specific disease such as diabetics have to be designed accordingly.

The objective of the study is was investigate the condition of the battle dress uniform worn by male members of the Korean Police Special Weapons Attack Team(KP-SWAT), identify problems, and provide basic raw materials for developing improved design of BDU. For this purpose, the researcher conducted a questionnaire survey on 92 male members of SWAT (Special Weapon Attack Team) units in Seoul using a questionnaire developed through observation and interview. Also, the body sizes of male SWAT members were measured. According to the results of body size measurements, male SWAT members generally require uniforms with a target bust girth, armhole, biceps circumference, thigh and calf circumference, longer jacket length, sleeve length, and trouser length to the knee. According to the results of the questionnaire survey, they reported dissatisfaction with the fit. In addition, they said that the Pockets are positioned too low for convenient use. Many subjects reported that their trousers were too short because of the rubber rings at the bottom of the legs. In addition, many subjects requested the alteration of the inconveniences caused by the designs finished with velcro on the bottom collar of the upper uniform, the marks and ensigns of the upper uniform, the bottom of the upper and lower uniform, and several pockets. Furthermore, there were many complaints concerning how they had to wear their uniform. The most frequently worn out and the body parts most often injured in field training and operations, they were reported, on the upper uniform, as the elbow, collar, neck, armpit, shoulder, and sleeve hem in that order, and on the lower uniform, the knee, interior calf, waist (belt rings), buttocks (rear pockets), and the bottom of the trousers (ankle) in that order As for questions concerning priorities in the improvements of the operational uniform and preferred design, the subjects recommended improvement in safety (protectiveness), workability (motional flexibility), design (shape), fit (size), comfort, ease in terms of putting on and taking off, etc., and the majority preferred two-piece designs ($67.4\%$), followed by one-piece ($30.4\%$), or both ($2.2\%$).

Purpose : The purpose of this study was to investigate subjective symptoms according to the wearing, purchase and fitting status of soft contact lens wearers, and consumer perception of base curve. Methods : A survey was conducted for those who visited optical shops and lens shops in Seoul from June to August 2018. A total of 98 answer sheets they submitted were used for the analysis. The chi-square test and Fisher's exact test were used to compare subjective symptoms (dryness, glare, uncomfortable fitting, and decreased vision) according to whether fitting condition is screened (case history and push-up test, ect relevant to wearing sensation), and the odds ratio (OR) was obtained by the logistic regression analysis. Results : When the contact lenses were purchased, the rate of which the visual acuity test was performed was 86.6% at optical shop and 64.7% at lens shop. When purchasing contact lens and the contact lens was not tested for fitting, they more experienced dryness (OR 4.41, 95% CI 1.25-15.62) and uncomfortable fitting (OR 2.68, 95% CI 1.08-6.64) than testing for fitting. In addition, it was investigated that 87.8% of contact lens wearers did not know about the term base curve, 92.9% did not listen to an explanation related to the base curve when purchasing contact lenses, and 96.9% did not experience with base curve test. Conclusion : It would be thought that satisfaction of the contact lens fitting of existing consumers should be improved by changing a proper base curve by confirming the fitting condition when prescribing soft contact lens.

The purpose of this study is to test the performance of the recommended summer dressing for office man through the analysis of skin temperature changes by air-conditioning temperature. We tested two clothing combinations; formal wear with necktie and casual shirts without necktie as for Cool mapsi. 4 male subjects sat to stabilize for thirty minutes after entering artificial-climate chamber with both temperature of $25^{\circ}C$, $27^{\circ}C$ and $50{\pm}10%$ R.H. And during 60 minute experiments of simulating office work, the subjective feelings including thermal, humidity and comfort sensation, skin temperature, clothing humidity and sweat amount were measured at the equal intervals. The result is that formal wear of $25^{\circ}C$ and Cool mapsi of $27^{\circ}C$ show good values such as low skin temperature, low clothing humidity and neutral thermal sensation. And Cool mapsi of $25^{\circ}C$ shows the risk of low rectal temperature for long and static energy level of office work. Formal wear of $27^{\circ}C$ shows high values of mean skin temperature, clothing humidity and thermal sensation. Second experiment was to find the ambient temperature when the subject wearing formal wear shows the skin temperature corresponding to which he shows on Cool mapsi of $27^{\circ}C$. The air-conditioning temperature on wearing formal wear has to be $2^{\circ}C$ lower to produce the corresponding skin temperature to which shows on wearing Cool mapsi of $27^{\circ}C$. Therefore it is possible to increase room temperature to $27^{\circ}C$, when wear Cool mapsi for summer office, for skin temperature and thermal sensation are produced the same.
