  • Suitability for the human body, freedom to move and thermal insulation are important design considerations in military clothing. This study investigates the performance and wearer-satisfaction of the functional inner winter uniform currently used in Korea; it is hoped that our data can inform the development of a future version. Interviews were conducted, in which the participants suggested various improvements. The uniforms were mainly worn for guard duty or as daily attire in cold weather. The participants chose how many layers to wear according to the current situation, rather than sticking to the layering recommended in the manual. Layering choices did not significantly affect combat efficiency but were found to affect wearers' comfort. Wearers' satisfaction was found to depend on the convenience of the clothing, whether it was in the appropriate size, freedom to move and thermal insulation. Also, this study suggests a problem with the current size system, as the analysis of size distribution, across all sizes, the range of current production is insufficient to cover the demand.

  • The purpose of this study is to investigate consumers' knowledge and preference towards functional cosmetics. Through the beauty advisors' surveys, their own selling styles and consumer behaviors recognized by beauty advisors were analyzed. It was intended to help extend and strengthen the functional cosmetic market which has continued to grow rapidly since the approved goods under cosmetic law in 2001. For this study, the data was collected through questionnaires the professional consumer counselors confirmed from Korean women over the age. of twenty old living in the Seoul and Kyoungki areas. After pre-research was implemented on 45 women, 328 samples were analyzed as final samples. In addition,46 samples, which were collected through the questionnaires from beauty advisors were analyzed. Samples were analyzed by frequency, percentage, T-test, ANOVA using the SPSS program. The results of study were as follows: First consumers recognized whether functional cosmetics or not. According to the beauty advisor's surveys, consumers regard the functional cosmetic boundary as being wider than real functional cosmetic boundary according to cosmetic law. So, there is a gap between consumers' opinions and real law. Second, regarding the purchasing channels, the largest channel is the cosmetic store. As far as consumers are concerned the most important factor when buying cosmetics, is the suitability of their own skin types. The second factor is product quality and the third factor is price. Functional cosmetics non-experienced group are more concerned with price compared to experienced group. Related to purchasing products, functional cosmetics experienced group buy set products compared to non-experienced group buy one product. Third, the ultraviolet filter cosmetics portion is the largest in the functional cosmetics market the second largest portion is bleaching cosmetics and the third largest portion is the anti-senility cosmetics. However, Most preferred by consumers is the anti-senility cosmetics. Moreover, preference for ultraviolet filter cosmetics is the least. Finally, the level of satisfaction for functional cosmetics is high and dissatisfaction is low. Consumers feel that beauty advisors are simply pushing high priced products without recognizing the consumers' real needs. In conclusion, to develop the functional cosmetic market continually in the future, it needs to extend various products and advertise them until consumers are more aware.

  • Large and complex structures are being built now-a-days and, they are required to be functional even under extreme loading and environmental conditions. In order to meet the safety and maintenance demands, there is a need to build sensors integrated structural system, which can sense and provide necessary information about the structural response to complex loading and environment. Sophisticated tools have been developed for the design and construction of civil engineering structures. However, very little has been accomplished in the area of monitoring and rehabilitation. The employment of appropriate sensor is therefore crucial, and efforts must be directed towards non-destructive testing techniques that remain functional throughout the life of the structure. Fiber optic sensors are emerging as a superior non-destructive tool for evaluating the health of civil engineering structures. Flexibility, small in size and corrosion resistance of optical fibers allow them to be directly embedded in concrete structures. The inherent advantages of fiber optic sensors over conventional sensors include high resolution, ability to work in difficult environment, immunity from electromagnetic interference, large band width of signal, low noise and high sensitivity. This paper brings out the potential and current status of technology of fiber optic sensors for civil engineering applications. The importance of employing fiber optic sensors for health monitoring of civil engineering structures has been highlighted. Details of laboratory studies carried out on fiber optic strain sensors to assess their suitability for civil engineering applications are also covered.

  • The market share of conglomerates is increasing in the Korean school uniform market these days. Functional fit problems occurred. Girls choose slim silhouette often experienced fit problems. The purpose of this study is to probe for functional design elements of high school girls' uniforms. A questionnaire survey was carried out. 202 high school girls took part in the survey. The questionnaire measured school uniform brand preference and size of school uniform jackets. The results of the survey show that over half of participants(56.6%) wore their jackets over nine hours per day. They considered the aesthetics of the design as the most important factor when purchasing school uniforms. That element affected their brand preference. In analyses of the fit suitability, there were no significant differences between brands. The jacket lengths were significantly different among brands, but all were evaluated as being short. About 60% of students had difficulty raising their arms while wearing their school uniform jackets. The results of this study revealed that high school girls' uniform jackets are too short and tight. Ergonomic design elements should be applied to high school girls' uniform jackets.

  • The purpose of the study was to investigate the effects of sea cucumber extract on skin as a natural cosmetics functional material. Subjective evaluation of cosmetics before and after were conducted with questionnaires regarding moisture content, sebum content, melanin index, and erythema index. Experiments were conducted on improvement efficacy using skin clinical trials and questionnaires to evaluate changes in perception of skin condition and efficiency of products. With the aim of minimizing skin irritation, the efficiency of the solvent used for extraction was an important factor, and the sea cucumber extract was harvested with efficient extraction conditions at a ratio of 1:10 of 50% ethanol. The study aimed to identify the suitability of sea cucumber extract as a functional cosmetics material to improve the moisturizing ability of skin and its effect on the skin by adding marine natural animal sea cucumber extract. Clinical studies on cosmetics skin containing sea cucumber extract, excellent skin improvement effect from all items of clinical experiment in experimental and control groups. Sea cucumber extract was proved to be a stable, non-adverse physiologically active substance against abnormal symptoms or side effects of skin reactions and skin problems. In addition, the study found excellent results that can lead to its use as a cosmetics material. This is expected to contribute to the development of various cosmetics industries.
