The aim of this study is to develop Casual Hanbok design made of Hanji yarn textiles for New Silver generation women. The New silver generation is a coined word which has meaning of a newly silver generation and it is distinguished from pre-silver generation. New silver generation is a generation that is independent and given active role by their age groups and generational characteristic. The concept of silver generation was introduced from maturity market in Japan. This study was based on analysis about their preference of forms, colors, and materials of Casual Hanbok. The survey target were 270 female over age 50 living in Daejeon City. The analysis methods used frequency and percentage. The results were summarized as following. Although almost of them haven't worn Casual Hanbok, they had the positive recognition on wearing one. They preferred longer length jacket to traditional Korean style, shorter length of skirt. They also preferred the traditional sleeve shape and knotted buttons. On the foundation of this fact, 2 styles consist of 5 Casual Hanbok design items made of functional material - Hanji yarn textiles that have antimicrobial, deodorant, quick drying, far infrared radiation which are not harmful to health - for New silver women were suggested. One style was 3 items - blouse, vest, skirt - which are the sense of Korean tradition with activity by patch. The other was 2 items - jacket and skirt - which are the sense of Korean tradition with modern way by quilting. Lastly, these garments were evaluated by 13 experts, they were satisfied with 2 styles and all items. As this study were based on the Elderly women living in Daejeon city, it had the limitation on applying of preference styles to all the New silver generation.

This study was conducted for silver generation women, age 60 and more. Questionnaire was answered by the total 291 of women. Frequency analysis, t-test, ANOVA and Duncon-Test have been completed by using SPSS 12.0 tool. The conclusion of the study is below. First, silver generation women live in Seoul and South Gyeongsang Province. The data shows huge academic background gab among regions. Second, the following is the preferences found by 15 stimulants which expert groups identified based on demography. People in South Gyeongsang Province like default, tailored, three-button jacket more. People in South Gyeongsang Province prefer to Chanel jackets and people in their 70s prefer to it than in 60s, stand collar casual jacket for color and material, and the less they are educated, the more they like the jackets. And those who have less personal expenses tend to prefer to it. South Gyeongsang Province shows preference for semi polo-neck sweater. Highly educated did not show any preference for it. Women in their 70s tend to like blouses with round neckline. The data shows there is significant difference of preference for design, color and material for coloration vest between education levels. The less educated tends to like it. People in South Gyeongsang Province and those who live with their children are in favor with half sleeve jackets for colors and materials. All in Seoul and South Gyeongsang Province do not like three-quarter-length sleeve jackets because those jacket have wide and deep plunging neckline. The study showed people living in Seoul, in their 60s, highly-educated tend to favor polo shirts significantly. Seoul favor basic straight pants and people with any level of education excluding elementary prefer to it. The highly-educated and those who have a bigger allowance tend not to prefer to baggy trousers. In conclusion, Fifteen incentives (clothing design) for semi polo-neck sweaters, polo t-shirts, basic straight pants are more proper to silver generation women in their 60s, living in Seoul. Other designs are desirably applicable to customers on a national scale at middle prices.

Nanomaterials have been used to create unique devices at the nanoscale level. However, the toxicities of nanomaterials have not been fully tested and the risk of nanomaterials has been raised as an emerging issue in these days. In this study, the cytotoxicity of silver nanoparticles was tested using cultured mouse leydig cells. As results, silver nanoparticles showed cytotoxicity with the generation of reactive oxygen species (ROS). With the increased level of ROS, intracellular glutathione level was decreased. DNA fragmentation and caspase-3 activation suggested the apoptotic mechanism of cell death in leydig cells treated with silver nanoparticles.

Silver nanoparticles (AgNPs) are widely used nanoparticles and they are mainly used in antibacterial and personal care products. In this study, we evaluated the effect of AgNPs on cell death induction in the murine dendritic cell line DC2.4. DC2.4 cells exposed to AgNPs showed a marked decrease in cell viability and an induction of lactate dehydrogenase (LDH) leakage in a time- and dose-dependent manner. In addition, AgNPs promoted reactive oxygen species (ROS)-dependent apoptosis and AgNP-induced ROS triggered a decrease in mitochondrial membrane potential. The activation of the intracellular signal transduction pathway was also observed in cells cultured with AgNPs. Taken together, our data demonstrate that AgNPs are able to induce a cytotoxic effect in DCs through ROS generation. This study provides important information about the safety of AgNPs that may help in guiding the development of nanotechnology applications.

우리나라는 세계에서 유례를 찾아보기 어려운 빠른 속도로 저출산과 더불어 고령화가 진행되어 가고 있다. 인구구조도 피라미드형 구조였으나, 최근에는 역피라미드형 구조가 되어감에 따라 생산인구 문제를 열악하게 만드는 요인으로 작용하고 있다. 노인 일자리사업은 이러한 산업구조 역행의 일부를 대체하는 측면도 있지만, 노인의 경제적 측면과 신체적 측면 그리고 사회통합의 측면에서도 효과적인 지원체계가 마련되어져야 한다.
