The effects of additive ions on the generation of metallic nanoparticles were evaluated using a corona induced supersonic nozzle. Applying the corona discharge to the nanoparticle generator, a tungsten needle and the supersonic nozzle are used as an anode electrode and a cathode electrode respectively. The corona ions act as nuclei for the silver vapor condensation. The ion density was controlled precisely as varying the applied voltage between electrode and nozzle. The mean diameter of the silver particle decreases as the ion density increases. However, the number concentration of the silver particle tended to increase with the ion density. The size distribution is more uniform as the ion density increases.

Older generations may want a life review, a dynamic process of recall, evaluation, and aggregation, to fulfill their developmental task of "ego-integrity." Writing an autobiography is a tool for a life review based on narrative as "mode of consciousness." This study intends to find out what should be considered so that digital autobiography can fulfill its original role as a tool to achieve ego-integrity for the New Silver Generation. For this purpose, we will first examine theories about the process of ego-integrity through a life review. Then we will analyze different aspects of writing an autobiography including three characteristics of being narrative and the compositional qualities of autobiographical writing. Next, we will review the characteristics of digital narratives autobiography, and highlight some ideas to consider in the study of digital autobiographies for the New Silver Generation.

Gold and/or silver mineralization in the southeast province, Korea, occurred in hydrothermal quartz vein that fills fracture zones in Cretaceous volcanic and sedimentary rocks of the Gyeongsang basin or granites and Precambrian gneiss. Most of the gold-silver-bearing veins in the province occur in Hapcheon, Suncheon and Haman-Gunbuk area where they are associated with Cretaceous Bulgugsa granites. On the basis of the Ag/Au ratio on amounts produced and ore grades, mode of occurrence, and associated mineral assemblages, hydrothermal Au-Ag deposits in southeast province, Korea, can be classified as follows: pyrite-type gold deposit (Group IIB, Samjeong and Sangchon deposits), antimony-type gold-silver deposit (Group IV, Gisan and Geochang deposits), and antimony-type silver deposit (Group V, Sanggo, Seweon, Seongju and Gahoe deposits). All of the gold-silver deposits in the province are generally characteristics of the gold-silver or silver-dominant type deposit which contains more silver-bearing minerals than those deposits in central Korea. The gold-silver mineralization in the deposits consist of two generation; the early characterized by gold precipitation and the late represented by silver-rich (as silver-bearing sulfosalts minerals) mineralization. All but one deposit (Samjeong deposit) having relatively lower Au content in electrum values between ${\approx}20$ and ${\approx}50$ atomic %. The mineralogical data on electrum-sphalerite and/or arsenopyrite geothermometry and fluid inclusion data indicate that the gold and silver mineralizations were occurred at temperatures of $190{\sim}280^{\circ}C$ and $150{\sim}180^{\circ}C$, respectively. These suggest that the gold-silver mineralization in the province occurred in the lower temperature and pressure conditions as epithermal-type hydrothermal vein deposit.

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.

This paper reviews about synthesis of nanoparticles by spark discharge and applications. A method of catalytic activation with Pd and Pt aerosol nanoparticles produced by spark discharge was introduced. After annealing, the catalytically activated substrate placed into a solution for electroless silver deposition. The silver was then formed only on the activated regions of the substrate. Silver line patterns having a width of $18{\mu}m$ and a height of $1{\mu}m$ were created with the ability to be effectively reproduced. Antimicrobial nanoparticles such as silver were used for removal of bioaerosols. Silver nanoparticles deposited air filters such as ACF filters were evaluated by antimicrobial test.

Silver nanowire-based transparent electrodes are very attractive as a next-generation flexible and transparent electrode that can replace ITO-based flexible electrodes because they have excellent conductivity, transmittance and mechanical flexibility. However, weak understanding of the silver nanowire solution for the fabrication of silver nanowire-based transparent electrodes often cause abnormal operation of the electrical device or peeling problem of the electrode films when applied to electronic devices. Here, we studied a Hydroxypropyl Methylcellulose (HPMC) adhesion promoter, which is one of the additives for silver nanowire solution, to improve the understanding of silver nanowire solution. In detail, it is characterized how the HPMC changes the properties of silver nanowire solution and silver nanowire film, which is fabricated with silver nanowire solution including the HPMC adhesion promoter. As the characteristics of solution, polar surface tension and dispersive surface tension were measured. As the film characteristics, surface energy, surface morphology, silver nanowire density, and sheet resistance were analyzed.

This study develops a new brassiere for new silver women. A new brassiere design was developed for the silver generation based on apreliminary survey; subsequently, a wire and no-wire type of brassier were developed after a second fitting evaluation. The results were as follows. First, in terms of brassiere design, the cup shape was designed as mold type full cup, shoulder straps were designed as camisole type with cups, bias tape was designed for body correction in the side line and mash tape was designed for easy movement below the cups. On the other side ofthe cup shape was a pocketdesigned on a support pad forthe wire type and a support panel to serve as a wire in the no-wire type brassiere. Second, brassiere patterns were designed by referencing the educational H pattern. Thetotal length was elongated by 5cmto reduce pressure when wearing a brassiere and the height of the front center increased by 8cm for the stability of the front center of the brassiere. In addition, the side line was moved back by 3cm and the width of the brassiere wings was designed widely at 10.5cm. Third, a wearing test was conducted for the wire type and the no-wire type brassiere with comparison products, using a 7-point Likert scale. Appearance results and movement tests for the wire and no-wire type showed a higher score than comparison products.

The purpose of this study was to investigate the need for a nutritional care service in silver town and identify awareness of the role of a dietitian in silver town using a structured questionnaire. The subjects consisted of 466 adults (216 males, 250 females), aged 20~59 years, in the Gyeongnam area. Although most of the subjects were aware of silver town and felt a necessity for it, only 24.9% of the subjects intended to live in silver town, whereas 55.6% of the respondents replied that they did not know whether they lived in silver town. Results on the importance of services offered in silver town indicated that medical service facilities, the interior and mood of silver town, the reliability of management, and meal service prepared by a dietitian were prioritized. Healthy food was the most valuable part of the meal service followed by taste. In total, 88.3% of the subjects answered that the meal service in silver town should be supervised by a dietitian. Clinical nutrition management was chosen as the most important job of the dietitian followed by sanitation management. These results could provide a better understanding of the personal needs of silver town, focusing on the meal service and the role of a dietitian.
