In this study, we aimed to apply 3D digital printing to basic clothing production and to propose futuristic fashion design and production methods that correspond to contemporary trends. Literature on future trends, dynamism, mechanical aesthetics, and experimentalism were used to define the characteristics of "futurism." Based on theoretical considerations about futurism, we created fashion designs using 3D digital printing methods. These designs were produced using the aesthetic characteristics of futurism; the 3D digital clothing program; and application of digital printing technologies to futuristic silhouettes, colors, and materials. The results were as follows: First, with the application of futurism as a fashion motif, we pursued collaboration between artistic work and fashion, and we then explored the possibility of creative expression. Second, harmony between achromatic and chromatic colors revealed even better dynamism and activeness, and the potential to express dynamism was observed. Third, with the development of fashion design processes based on 3D digital printing methodologies, it was found to be possible to eliminate the limitations of time and space, solve problems related to limited budget or communication, and positively influence the fashion industry by enhancing convenience and diversity. Fourth, with the development of fashion design that utilizes digital printing, it was found that problems related to time, space, or limited budget were able to be solved, as compared to the use of traditional printing and image reproduction.

Background: N-nitrosamines are carcinogenic substances often found in rubber products. They are produced when certain additives of rubber products react with nitrite in saliva or air. Exposure assessment for the proper management and communication of N-nitrosamines in rubber balloons should be carried out. Objectives: This study was conducted to determine the concentrations of N-nitrosamines in rubber balloons in the South Korean market and assess exposure among Korean children. Methods: Forty eight rubber balloon products in the domestic market were purchased and a total of 68 balloons were analyzed for N-nitrosamines and N-nitrosatable substances. Chemical analysis was conducted by HPLC-MS/MS according to the method EN 71-12. For exposure assessment, an exposure algorithm and coefficients were obtained from previous studies. Results: Among the 68 rubber balloons, N-nitrosamines were detected in 18 (26.5%) with an average level of 60.77 ㎍/kg. N-Nitrosatable substances were detected in 44 products (64.7%) with an average level of 1353.33 ㎍/kg. As a result of the exposure evaluation, the exposure dose differed according to how exposure coefficients were applied. The median exposure (50th percentile) was higher in the age group of 6~12 years, and high exposure (95th percentile) was higher in the age group of 13~18. Conclusions: We evaluated the N-nitrosamines contained in rubber balloons purchased in the domestic market and assessed oral exposure among South Korean children. For integrated risk management of N-nitrosamines, further studies and discussion regarding exposure and risk assessment are required.

Background: As the public interest in chemical substances found in daily life has increased, environmental health education content has been developed and related studies have been conducted. However, there is still insufficient research on methodologies for environmental health education. Objectives: This study aimed to explore risk communication strategies by focusing on N-nitrosamines in rubber balloons. Methods: In this study, two different health messages were composed: a gain-framed message emphasizing the advantages of practicing the health behavior and a loss-framed message emphasizing the negative consequences of not practicing the health behavior. The effect of the message containing risk information was evaluated by measuring the health beliefs and health behavior potential for female caregivers. As the Environmental Health Act defines a child as "a person under the age of 13," a total of 131 women with children under the age of 13 were studied. Results: The age, awareness, and interest of the participants in the gain frame group and these in the loss frame group were similar. In terms of message framing effect, the gain-framed message was more effective in terms of health belief and potential health behavior than was the loss-framed message. As a result of an independent t-test, among the six variables of health belief model the message effect was statistically significant at the level of p<0.05 in three variables: perceived severity (t=2.287, df=129, p=0.024), self-efficacy (t=2.123, df=129, p=0.036), and health behavior potential (t=2.094, df=129, p=0.038). Conclusions: This study presented a direction for effective environmental health education by studying the effects of risk communication messages based on scientific evidence. It is necessary to extend the scope of environmental health education research by expanding research into various household products.

The purpose of this study was to propose the direction of veganism-based fashion design in environmental and animal protection through the theoretical consideration of vegan fashion and the analysis of the practical design characteristics of veganism in Stella McCartney's fashion. The research was conducted through literature research and case studies. After investigating the concept and characteristics of vegan fashion, focusing on previous studies and various fashion-related Internet data, Stella McCartney's fashion was examined with particular attention on vegan characteristics. The results of the study are as follows: First, imitative nature pursues animal and environmental protection, but the motif or appearance is a characteristic of pursuing a multi-purpose design that imitates animals and nature. Second, expression of value is based on slow fashion, simplicity, and sustainable minimal design. It is expressed indirectly by pursuing permanence, simplicity, and long-wearable design, or directly expressing vegan values through phrases expressed in performances or costumes in the collection. Third, alternative eco-friendliness is characterized by using cruelties-free materials such as faux fur, recycling materials, new bio-materials, and regenerated materials. These vegan characteristics are comprehensively and organically expressed in the works of the collection, and through this, sustainable and eco-friendly vegan fashion is pursued. It is anticipated that by deriving the vegan fashion characteristics of Stella McCartney, who represents vegan fashion, it will be possible to provide the basis for practical direction and design methods for fashion brands aiming for vegan fashion styles.

The realistic plan to establish a silver market in the clothing industries has not taken concrete shape, although the interest in the establishment of a silver market targeting the aged as a new custom group Is gradually Increasing because the rapid development of science and medical technology in the 20th century has led to an extension of lift and improvement of living conditions. The specialized business which produces and sells the clothing for the elderly is of small number and most of the clothes for the elderly are manufactured and sold by the companies for women's clothing in which change the size or length of the original works rather than reflect the bodily features of the elderly. The findings indicated that domestic brands showed the coordinated concept of a suit of jacket and slacks or skirts while the clothes were formed with a variety of coordinations centering around single article in the U.S brands. But, there was no difference in the use of natural materials centering around cotton and silk etc. and in the use of embroidery, lace and decorative details between the two countries. The knit brands of knit suit style in Korea were formed with the items focused on pull over and cardigan twin set, while the U.S brands were mainly formed with the design of knit suit style. The domestic knit brands were mostly developed with complicated patterns and gorgeous colors, while most of the U.S. brands were presenting a single or two tone color suit style and evening one-piece dress with a simple and modern style. The sporty casual brands of sporty casual style in Korea had a variety of colors and patterns focused on function and comfort for diverse leisure activities and daily life, while the U.S brands were established to present a variety of styles with the items of single article because they had a separate brand for casual even though it was not a exclusive brand for the elderly This study has a meaning in the presentation of the design idea considering the bodily shape of the elderly compared to the ready-to-wear considering the size alone, by examining the characteristics of bodice according to the physical change of the elderly women, analyzing the design of madam brand and the style of the ready-to-wear, researching the general circumstances of the brand for the elderly women, and highlighting the necessity of the elderly clothing market.

본 연구에서는 직/편물 8종을 대상으로 이들 수직방향과 수평방향 수분이동특성 측정방법에 따른 소재들의 수분이동 특성을 분석하였다. 또한, 8종의 시편의 MMT에 의한 건조특성을 수직 건조 측정 결과와 비교하여 논의하였다. 수평수분이동 방법인 MMT 시험 결과는 수직법인 바이렉 방법의 결과와 유사한 거동을 나타내었다. 대나무, 린넨 및 면/나일론 복합 소재는 드롭법의 흡수시간은 짧았으며, 표면의 낮은 접촉각 및 직물의 높은 다공성에 기인한 것으로 판단되며, 친수성 스테이플 섬유의 구조와 상관이 있을 것으로 보인다. MMT에 의한 건조특성은 니트 및 대나무 직물의 최대 흡수반경이 가장 우수했으며, 수식 건조법에 비해 차이를 나타내었다. MMT 방법의 건조속도는 직물의 두께와 포화수분 흡수율과 높은 상관성을 가졌으며, 회귀계수는 각각 0.9와 0.88이었다. 이는 직물의 두께가 얇을수록 위킹 및 건조특성이 우수하며, 기능성 소재기획시 착용 내구성을 판단하는데 중요함을 의미한다. 또한 상이한 섬유소재, 실 및 구조의 소재에 대한 수분이동특성(위킹, 건조)는 측정 방법에 따라 다른 결과를 나타내었다.
