As the aging population has increased, the silver generation is getting to account for the considerable percent of economic activities and becomes the main body of production and consumption. Although the economic activity of silver generation is increased, the development of silver contents for the leisure activities is still not revitalized. The serious silver contents and the easy-to-use interface are very important because the silver generation is relatively weaker than young people in perception, studying, and exercise, and is fragile in mobility and vitality. This paper suggests methods to develop sensory bicycle, gate ball, and mole game contents haying lower body exercise effects for the silver generation to utilize leisure and maintain health. Along with fun as games, functional design factors suitable to the cognitive ability and bodily activity ability of the silver generation were considered and through sensory intefaces that are easy for the silver generation to use and customized progressing methods complying with individual characteristics, it was attempted to induce continued interests and lower body exercise effects.

Unlike the past, the elderly who are growing rapidly in Korea are called 'active seniors'. They prefer to live in urban silver towns despite high living cost and make their own new urban contents. The new urban contents that reflect the living characteristics of active seniors have an important impact on their choice of residential location. Therefore, the purpose of this study is to identify the location characteristics of urban silver towns, which are preferred as the main residence of active seniors, based on the urban living contents of active seniors. The location characteristics of urban silver towns considering the urban living contents of active seniors can be classified 1) public transportation, 2) nearby arterial roads, 3) culture shopping facilities, 4) medical facilities, 5) apartment complexes, and 6) natural environments. Especially, the accessibilities of medical facilities, apartment complexes, and culture shopping facilities were the main characteristics of urban silver towns. The results of this study are expected to be helpful not only the location of urban silver towns, which is the urban new content of active senior, but also for the policy on housing for the elderly.

This study defines the silver portal as a specialized internet portal that will be probably popular with the pre-senior/senior internet users who are over 40, sooner or later. The purpose of the study is to analyze what types of online contents on the silver portal are mostly preferred by the pre-senior/senior, and does the preference of those content types vary according to the demographic and the internet usage characteristics of the pre-senior. The study also is to suggest some research propositions, based on the analysis results, that could be applied to empirical studies in the future which deal with various research questions on the silver portal. To accomplish these research purposes, the study performed a survey for the prospective silver portal users who are living in the areas of Seoul and Kyeonggi, South Korea, and did various statistical analyses. This study found that the preference of content types of the silver portal vary according to some personal characteristics of the prospective silver portal users, and moreover proposed a few of research propositions on the relationships between personal characteristics and preferred content types.

The purpose of this study is to suggest design characteristics of picture books for silver generation empirically through academic consideration of necessity and characteristics of picture books targeting silver generation. Through an analytical result of literature materials such as library and information science, pedagogy, and literature therapeutics, and aging phenomenon, picture books help mental and physical health of silver generation, but picture books for silver generation are insufficient in comparison with demand. Therefore, a theoretical basis of study and development of fairy tale books for silver generation is acutely needed. This study suggested that close attention for characteristics of silver generation is needed to solve a problem about dyslexia of silver generation in story, picture(expression, size, layout, structure, and color), and typography of characteristic factors of picture on designing fairy tale books for silver generation, suggesting needs to develop picture books reflecting characteristics such as visual organ, body function, and psychological factor of silver generation. In addition, design characteristics for composition of picture books for silver generation will be used as part of advanced data in a study on solid analytical data through an actual analysis on silver generation in the future.

The purpose of this research is to suggest improvement of web environment to supplement dependency of silver generation as we have aged super aged society ahead. In order to improve web environment for silver generation which has more various obstacles than common people, I examined methods to increase accessibility and usability through expansion of web interface by reinforcing contents structure and function. As a result, the try to increase web usability of web sites related to silver generation was positive, but interface designs are not unified which requires users to learn new skills, and developer produce designs that are not standardized. Therefore, I suggest web environment improvement methods to guide silver generation to be adapted to information society by suggesting solutions such as support for module of operation system and establishment of standardized design.

Effects of nano-silver contents(15~50wt%) on screen printed-etched gate electrodes and electrical characteristics of OTFTs were investigated. As Ag contents increased, the screen-printed film was transferred exactly without spreading and obtained the densely-packed layer with a stable and excellent conductivity but, its thickness was increased and surface became rougher. It was found that the leakage current of MIM devices and off-state currents of OTFTs became larger due to poor step coverage of PVP dielectric layer on the thick and rough gate electrodes for nano-Ag inks with Ag contents more than 30wt%.

Silver conducting films were formed from nano-sized silver powders and glass frits prepared by flame spray pyrolysis. The mean sizes of the silver powders and glass frits were 73 and 63 nm, respectively. Nano-sized glass frits improved the adhesion strength of the silver conducting film to the glass substrate. The densities of the silver conducting films increased by increasing the glass contents of the films at firing temperatures of 400 and $500{^{\circ}C}$. The specific resistances of the silver conducting films with 5 wt.% glass of silver component were 7.8, 4.2 and 2.4 cm at firing temperatures of 400, 450 and $500{^{\circ}C}$.

Holography technology which was developed by Dennis Gabor (1900~1979) in 1948 is a technology to record wave planes of actual 3D objects. It is known as the only technology which can express 3D information most perfectly close to human-friendly. Holography technology is widely used in advertisement, architecture and arts as well as science technology areas. Especially, digital holographic print which is an applied area is greatly used in military map, architecture map and cultural asset restoration by printing and reproducing 3D information. Holography is realized by recording and reproducing the amplitude and phase information on high resolution film using coherent light like laser. Recording materials for digital holographic printer are silver halide, photoresist and photopolymer. Because the materials have different diffraction efficiency according to film characteristics of each manufacturer, appropriate guide lines should be suggested through efficiency analysis of each film. This paper suggests appropriate guide lines through the diffraction efficiency measurement of silver halide which is a holographic printer recording medium. And the objective of this study is to suggest appropriate guide lines through diffraction efficiency analysis of Ultimate 08-C and PFG-03C which are commercially used. The experiment was prepared by self-diffraction efficiency system which measures the strength with the defector by penetrating RGB recording medium and concentrating diffracted beams through collimating lens. The experiment showed Geola's PFG-03C which is a silver halide for full color has price/performance advantage in optical hologram recording, but recording angles and reproduction angles are irregular for digital holographic printer recording. Ultimate's Ultimate08-C for full color shows its diffraction efficiency is relatively stable and high according to recording angles and laser wavelength.
