Recently, human's life is more longer and the birth rate continually decrease by the development of medical technology. In 2026 the ratio of the elderly will come up to 20.8% and be a 'post-aged society'. Development of economy and industrialization not only accelerate the urbanization and formation of nuclear family, but also change the changing of traditional society and one's value. So the issue of society and value's changing in the elderly increase the centralizing in the silver industry, and by the recent research about the elderly, they not want to live with their children, but want to live independently. This study is meaningful at the next generation of Ubiquitous society and post-aged society, proposing the smart silver town in urban type and let the elderly keeping the existing life in city. It realize the concept of 'Aging in Place' and propose the smart silver town in urban type which appropriate to behavior of the elderly, and being satisfy with various requirements of the elderly. This study point up the combination of physical elements and electronic elements through the smart technology, and making an smart environment to compose the smart silver town in urban type which react the behavior of the elderly.

Synthesis of silver nanoparticles by the supersonic nozzle expansion method with corona discharge ions was investigated. Corona discharge ions functioned as seeds for heterogeneous nucleation in the silver nanoparticles formation process and provided silver nanoparticles with electronic repulsive force that prevents aggregation of the particles. For ion ejecting, we used sonic-jet corona discharger. Upon application of the corona discharge ions, the mean diameter of the produced particles was decreased from 12.54 to 6.22nm and the standard deviation was decreased from 5.02 to 3.34nm. In addition, the agglomeration of silver nanoparticles was reduced.

The purpose of this study is to analyze the relationship of information literacy, life satisfaction, and life happiness of the silver generation, and to suggest the direction for their happy life. We conducted a questionnaire survey targeted at the Internet users of over 60 years old adults living in Daegu/Gyongbuk areas. Data were analyzed using 238 valid samples. With the results, it revealed that the silver generations' life satisfaction fully mediates the relationship between their information literacy and their life happiness. Future studies are also discussed in this paper.

The purpose of this study was to investigate the effect of self-efficacy and appearance interest on appearance management and clothing purchase behavior of new silver generation. The research method was a survey method using a questionnaire. The subjects were 300 new silver woman(aged from 50 to 64) living in the large city. Statistical analysis methods were factor analysis, Cronbach's ${\alpha}$ and multiple regression analysis. The results of this study were as follows. The self-efficacy factor divided into three categories including self-control efficacy, social self-efficacy and physical self-efficacy. And appearance interests were divided into four categories including weight control interest, outfit management interest, interest in clothing and disinterest in appearance. Self-efficacy had significant effect on various appearance interests. Especially physical self-efficacy was the important factor which could describe the appearance interests more effectively. Self-efficacy and appearance interests had significant effect on appearance management and clothing purchase behavior. Social self-efficacy could describe more appearance management behavior, while on the other side self-control efficacy could describe the clothing purchase behavior more effectively.

The purpose of this study was to examine new-silver women's fiber and material property preferences and purchasing behaviors. The survey subjects were 115 new-silver women ranging in age from 50 to 60 years old. This study utilized a questionnaire as a measurement tool. The results of this study were as follows: First, the home ownership rate of the participants in this was 81.4%, and 54.9% of them had a bachelor's degree or higher. Therefore, they turned out to be a new silver generation with higher education and stable income and assets. Second, regarding their purchasing behaviors, it was shown that they purchased the largest amount of clothing for themselves and their spouses, children, and grandchildren at the change of seasons. Third, with regard to their average spending on clothing, when they purchased clothing for themselves, it was shown that they purchased clothing at the price of KRW 500,000 or above for themselves but not for their family members. Fourth, their favorite type of fiber was synthetic fiber, and their favorite material property was heaviness, followed by roughness, stiffness, bulkiness, and glossiness. Moreover, with regard to their favorite functional textile, it was shown that the highest percentage of them preferred vitamin textiles, followed by ocher and scented textiles.

한국은 이미 2000년 7월 1일을 기준으로 65세 이상의 인구가 전체 인구의 7.1%를 차지해 고령화사회로 진입했다. 본 연구는 이들 고령인구(이하 실버세대)의 선행연구 되어있는 컬러선호도와 제품/상품의 관여도에 따른 실제 구입컬러의 차이를 요인과 함께 분석함으로써 실버산업의 가능성과 컬러마케팅의 효용성에 관하여 연구하였다. 본 연구는 향후 맞이 할 고령화 사회에서 소비의 주체로 떠오르게 될 실버세대와 기업과의 커뮤니케이션에 있어 중요한 데이터로 활용 될 수 있을 것이다.

The polynuclear hydrocarbons (PAHs) emitted from coke oven standpipe were sampled using three sampling systems, including glass fiber filter+silver membrane filter, glass fiber filter+silver membrane filter+XAD-2 adsorbent tube, PTFE membrane filter+XAD-2 adsorbent tube, extracted by methylene chloride and analysed by gas chromathography using flame ionization detector. The results of this study were as follows. 1. Because the amounts of coke oven emissions(COE) were large, the analyses of PAHs were simple and possible without evaporation and concentration. Although the generation of COE was high during early stage of coking, the airborne concentration of PAHs was low and increased during late coking. 2. The contents of PAHs in COE were 1.35-2.81%. 3. The index components of PAHs were fluoranthene and pyrene. Their correlation coefficient to total PAHs were 0.96, 0.95, respectively. 4. The particulate PAHs were sampled by filter and gaseous PAHs by adsorbent tube. The collection efficiency of glass fiber filter+silver membrane filter was 20% of total amount sampled by filters+adsorbent and PTFE membrane filter 50%. Adsorbent tube must be attached to the filter to collect light and small PAH components. 5. The generation of acenaphthene and indeno (1,2,3-cd) pyrene were low and concentrations of fluorene and anthracene were $20-40ug/m^3$ throughout coking time. Other PAH eoncentrations were sometimes high. The generation of PAHs was low at 4-6 hours of coking time. The gaseous PAHs were generated earlier than particulate PAHs.

A two-photon induced photoreduction process suggests a possibility for fabricating complicated metallic microstructures which can be applied to 3-D micro-circuits and optical devices, etc. The process employs the photoreduction of silver ions in a metallic solution which is composed of metallic salt ($AgNO_3$) and watersoluble polymer ((poly(4-styrenesulfonique acid) 18wt. % in $H_2O$, $(C_8H_8O_3S)_n$)). In this process, the improvement of the resolution and the uniformity of fabricated metallic structures are important issues. To address these problems, continuous forming window (CFW) is obtained from a parametric study on the conditions of laser power and scanning velocity and the direct seed generation (DSG) method is proposed. Silver nano particles are uniformly generated in a metallic solution through the DSG method, which enables the decrease of a laser power to trigger the photoreduction of silver ions as well as the increase of metal contents in a metallic solution. So the two-photon induced photoreduction property of a metallic solution is improved. Through this work, precise silver patterns are fabricated with a minimum line width of 400 nm.
