This study identifies the relationships among demographic variables, well-being health consciousness, sports/leisure activity, and the perceived premium price for high functional sports/leisure wear. An empirical study was conducted with the data collected by questionnaires distributed to male and female respondents aged 15 and over. Descriptive statistics, factor analysis, MANOVA, two-way ANOVA, and regressions were used to analyze 244 answers. As a result, 3 factors were determined for well-being health consciousness: nature-friendly life, premium consumption for health, and health care. The older group pursued a nature-friendly life more than the younger group, the female group pursued premium consumption for health more than male group, and older women and younger men pursued health care more than their counterparts. Sports/leisure activity was relatively intensive in the male group and in the younger group. Sports/leisure activity was explained by male characteristic and health care factors. Sports/leisure activity was the only element for predicting the perceived premium price ratio for high functional sports/leisure wear.

This research developed maternity wear designed with a focus on the essential functions necessary for working women and adaptable to their body changes during pregnancy. Through Martin's anthropometry for 201 pregnant women, the size specifications for maternity wear was determined and a dress form was proposed, in order to provide the manufacturer with reference data and a prototype to verify their products' fit and suitability. From a monthly analysis on the body measurements of pregnant women, significant monthly differences and after pregnancy were found in weight, chest girth, bust girth, under bust girth, waist girth, and hip girth. Dress form was designed based on the average body measurements of women in their 6th to 10th month of pregnancy. The standard dimensions in the 8th month were 90cm (chest), 94cm (bust), 86cm (under bust), 97cm(waist: most protruding part on the side), and 99cm (hip). Compared with Japan's MAT-9 (for nine months), chest girth was the same, while the Korean waist girth and hip girth were larger by 2cm and 3cm, respectively. The woven fabric blouse was evaluated as having the best appearance, while the knitted fabric one was judged as being more comfortable it terms of functionality. For the pants, the design details of the lowered waist and curved waist belt were more functional. The tailored jacket was the best design for working women in terms of both looks and functionality. To summarize, maternity wear for working women, unlike general maternity clothes, should be designed with consideration for the wearer's somatotype and activity. Elastic materials were appropriate for functionality and dealing with physical changes. With the increasing of working pregnant women, such trials are expected to continue in this research area in order to develop functional maternity wear with multi-purposes such as breast-feeding, wearability after delivery and shielding from microwave.

The purpose of this study was to propose a product planning and design direction for smart fitness wear that will improve the impact of personal training based on researching the requirements of smart fitness wear and its acceptance level, as well as the functional demand. The study conducted in-depth interviews with professional fitness trainers and derived five categories and thirteen keywords by analyzing the categorical data analysis using the interview data. In addition, we surveyed general consumers to measure the acceptance level of smart fitness wear and the functional demand for product development. The results revealed that the difference in the acceptance level of smart fitness wear generally depended on the characteristics related to exercise involvement and exercise-related culture rather than on the demographic characteristics. With regard to the difference in the functional demand of smart fitness wear, the results showed that professional trainers focused on the scientific improvement of the effect of exercise while general consumers focused on the function that considers the sustainability of exercise. Based on the results, we proposed product planning and design directions such as 'mounting of heart rate sensing, muscle activity sensing, motion angle or posture sensing, and motion sensing', 'development of concepts and contents for expert line, ordinary line', 'compression wear design', and 'differentiation of product development according to exercise areas'.

At present. about 0.3 million and more THRs (Total Hip Replacement) in a rear are being done worldwide. The increase in mechanical failure with the increase in THR, required more revisions. Revisions compensate mainly the wear of the artificial joint frictional surface and the loosening of the cup and stem. According to recent researches, loosening is mainly due to wear debris UHMWPE (Ultra High Molecular Weight Polyethylene) from frictional surfaces . To overcome the wear problems associated with artificial joint materials , new surface structures with regular Patterns were designed and fabricated The lubrication Properties were examined to evaluate the wear of the frictional surfaces. The surface structure manifested a Pattern of "dents" with a 0.2-1.0 mm of diameter and 0.6-2.0 mm of Pitch. From the friction test of the SUS316L vs UHMWPE using the frictional tester, we found that the lubrication Performance was improved due to of drastically reduced amount of abrasion. There were optimum sizes for the diameter and the pitch of the Pattern. The results demonstrated that the lubrication properties could be improved by Patterning of the frictional surfaces. The surface Patterning was effective in preventing wear of the frictional surfaces, and the life of an artificial joint could be extended with such Patterning.

Sports climbing requires more maximum body motion range than any other sport. This study examined what element affects the actions of sports climbers and suggest an ideal pattern archetype to maximize function based on motion. The theoretical background included abstracted elements influencing clothing design by researching the body type of sports climbers and the motion of sports climbing. Along with the characteristic of climbing wear, this study also conducted a comparative analysis of sleeve patterns for sports climbing wear and general sports jackets, abstracting comparative parts that influence sports climbing wear design. To develop the final research archetype, research was done on 107 sports climbers in their 20s-30s that selected the top 3 brands and collected patterns as well. A research archetype was selected based on 3-D virtual clothing and developed into 4 different patterns with different sleeve cap heights. Appearance evaluation and a motion functionality evaluation were then conducted in order to select a final research archetype adequate for sports climbing based on evaluation findings. In addition, this study identified aesthetical problems of the final research archetype produced based on functionality that could suggest an archetype for a climbing jacket that could be visually satisfying through appearance evaluations and motion functionality evaluations.

Modern fashion manifests in forms that mirror the diverse lifestyles and personalities of consumers. It transcends mere aesthetic designs and embodyies practicality. There is a preference for comfortable, highly functional attire, leaning towards easy wear. Casual wear, in particular, embraces a sense of freedom not found in standard business attire. It seeks a comfortable, natural silhouette through tactile fabrics rather than sportswear. Loose, drop shoulder sleeves enhance comfort and mobility and often become key elements in casual wear designs. Given that clothing must balance aesthetics with functionality, especially across various activities, it is natural to prioritize functional design. Research on patterns suited for dynamic conditions is imperative. The rise of drop shoulder styles necessitates the development of corresponding sleeve patterns. It is crucial to differentiate pattern drafting methods due to the resulting silhouette variations. This study aims to categorize drop shoulder pattern drafting techniques based on shoulder extension and angle dimensions. Each method will be examined, and drop shoulder sleeve patterns and wear forms will be studied using a 3D virtual system. This research holds significance in providing valuable insights and foundational data for designing diverse drop shoulder sleeve patterns, contributing to their practical development and advancement.

The objectives of this study mere 1) to investigate whether the different nonwoven fabric types influenced on the objective and subjective wear performances of the experimental pesticide protective pants, 2) to detect whether the different finishes treated to the nonwoven fabrics influenced on the objective and subjective wear performances of the experimental pants, and 3) to detect the relationships between objective wear performances and subjective wear sensation. Three types of nonwoven fabrics (T (Tyvek$\textregistered$), 5 (Sontara$\textregistered$) and K (Kimlon$\textregistered$)) were used as test specimens. By pad-dry.cure method, each of the specimen was treated with fluorocarbon compound for water-oil repellent finish (Tw, Sw, Kw). And each of specimen was treated with organic silicon quarternary ammonium salts and then treated with fluorocabon compound for dual functional finish (76, 50, Kd). Using the three water-oil repellent finished fabrics and the three dual functional finished fabrics, six experimental protective pants (Cl (Tw), C2 (Sw), C3 (Kw), C4 (76), C5 (56), C6 (Kd)) were made according to the same pattern suggested by the Rual Guidance Office. The wear trials of experimental pesticide protective pants were performed in a conditioned vinyl plastic hothouse ($30\pm1^{\circ}C$, $70\pm5%$R.H., 0.25m/sec air velocity). The measurements of skin temperature, microclimate temperature and humidity on the subjects were obtained by the themohygromenter. The subjective wear sensations were measured using previously developed thermal, humidity and overall comfort scales. The results obtained from this study were as follows: 1) There were siginificant differences among nonwoven fabric types on the objective and subjective wear performances, therefore, the skin temperature, microclimate temperature and humidity of subjects who wore the experimental pants made with Sontara were siginificantly lower than those who wore the others. And, the experimental pants made with Sontara were assessed as more comfortable than the others in terms of the subjective thermal, humidity and overall wear sensations. 2) There were no significant differences between two finish types on the objective and subjective wear Performances. 3) The microclimate humidity on the thigh was highly correlated with the overall subjective comfort sensations and the next highly correlated one was the mean skin temperature. That is, the higher the microclimate humidity and the mean skin temperature, the higher the overall subjective comfort sensation ratings which mean the overall subjective sensation was very uncomfortable.
