The increased average life expectancy and an aging society mean a lot of change socially and economically. With the increased population of the new elderly generation, holding a desire to pursue high quality life, plans and marketing strategies towards this group have progressed in the clothing industry. Purchases of clothing will lead the silver clothing industry to a huge consumer market and silver clothing brands are expected to have a lot of potential to grow, especially in department stores in Korea. From now on, there is a need for attacking the market with distinct tactics and characteristics that will satisfy the elderly consumers emotionally. Psychological views towards the elderly generation must be changed and our unique environment state must be considered.

Silica hybrid silver nanoparticles showing the strong antimicrobial activity, in which nano-silver is bound to silica molecules, has been synthesized using ${\gamma}-irradiation$ at room temperature. The present study relates to an antimicrobial composition for coating fiber products comprising silica hybrid silver nanoparticles. In this study, we describe antimicrobial fiber products coated with the silica hybrid silver nanoparticles and a method of antimicrobially treating fiber products by coating the fiber products with the silica hybrid silver nanoparticles. The antimicrobial fiber products exhibited excellent antimicrobial effects. In detailed practice, when the present composition comprising nanosized silica-silver was applied to a cloth (fabric) in a concentration of $6.4mg\;yard^{-1}$, the viable cell number decreased to less than 10 cells before and after laundering, resulting in a reduction of 99.9% or greater in the viable cell number. The present composition displays long-lasting potent disinfecting effects on bacteria. Also, we investigated the toxicity of silica hybrid silver nanoparticles in rats. The skin of rats was treated with a 30 ppm nanoparticles solution ($2ml\;Kg^{-1}$) for 8 days. No toxicity was detected in the treatment. These results suggest that the fiber products coated with the silica hybrid silver nanoparticles can be used to inhibit the growth of various microorganisms.

The purpose of this study was to develop an understanding of older consumers' lifestyle, and to provide the basic information for developing silver commodities and, in turn, to stimulate the silver industry which has received attention as a next-generation industry. The study divided elderly consumers into four lifestyle categories and analyzed the difference in demographic characteristics among these categories as well as differences in demand for silver products. Data were collected with questionnaire and analyzed with frequency analysis, factor analysis, K-means cluster analysis, one-way ANOVA, and a $x^2$ test using SPSS 15.0. Four different lifestyles categories were identified among elderly consumers : conservative and stability oriented (22 persons, 33.3% of the sample), progressive and relation oriented (22 persons, 15.0%), reality adapted (52 persons, 35.4%), and traditional (24 persons, 16.4%). The demand for silver products demands was significantly different among elderly consumers in the four different lifestyle groups.

As the population of the silver generation is increasing, the importance and effects of the market for the silver generation are also growing. We segments the categories of the silver generation into six sub-segments using based on the factors like life style, life stage, or performing role from the point of view in communication industry. After segmenting those categories, we observed the experience of each segmented group in detail. Likewise, we executed both FGD(Focused Group Discussion) and participants' observations together to effectively collect the expressed and/or potential needs. Customer's experience was collected along the touch points and customer corridors after dividing the customer's experience world into two groups; communication styles in usual life (life log) and direct contact channels. The effects of delivering an affirmative customer's experience would be empowered by eliminating negative experiences or complementing affirmative experiences. For this purpose, this paper presents the improvement points for the better customer's experience based on the observed customer's experience. This paper presented a sample way of customer-centric approach to design the services or products in the communication industry. In addition to that, the analyzed results of this paper will be useful to find out an effective approach to the market of silver generation.

The phenomenon of increasing aging population is one of the crucial social and economic issues in these day. In this paper, drawn from the industrial application cases and relevant literatures, we present the typology of ICT convergent applications targeted for silver generation, referred as silver ICT. Subsequently, the contributional value of ICT as the enabling technology is estimated. We firstly conduct keyword search to collect currently used silver ICT applications. Secondly, drawn from the social welfare literature, we organize distinctive needs of the silver generations. Then, on the basis of task technology fit framework, typology of ICT enabled silver applications is organized through the fit of ICT in the sense of fulfilling those silver needs. Finally, using the industry input-output table figures, potential ICT contributions for silver ICT are estimated. The proposed silver ICT typology and ICT contributions provides useful insights for further research in the area of ICT convergence and silver market research.

Out of the OECD countries, Korea is showing the fastest growth of elderly population. Taking into account the rate of increase of the elderly and average lifespan, we can deduct that the future society will be an elderly society . Therefore, the market in Korea targeted to this group will quickly increase into a large market. Leading nations already into the elderly society , have actively pursued studies into silver generation product design and compared to these countries, Korea is far behind them. There is an immediate need for a detailed overall study on the design of products used daily by the elderly, This study has based its focused on the elderly society and silver generation products and was accompanied by thorough interview research method through questionnaires. The result showed that the Korean elderly were very aware about silver generation industry. However, they Pointed out that there are many Problems regarding silver generation products. Therefore, a need for a new design reflecting more of the lifestyle of the elderly is required.
