Effects of citrate-capped silver nanoparticles (AgNPs) on the blood coagulation and platelet aggregation were investigated using whole blood, platelet rich plasma (PRP) and washed platelet obtained from SD male rats. To confirm the stability of AgNPs in the test, size distribution of the nanoparticles was measured in the vehicles including distilled water, serum, and platelet buffers. The average size of AgNPs was 20 nm in the vehicles, which means that the stability was maintained during the whole experimental period. When blood coagulation was monitored by using whole blood impedance aggregometer, coagulation was not observed at the concentration of 1, 10 and 50 ppm. Platelets in plasma or in buffer were not aggregated by AgNPs at the concentration of 1, 2 and 4 ppm, respectively. The test concentration of AgNPs could not be increased because the dark color of the nanoparticles impeded the transmission of light, which is an indicator of aggregation. Although the blood or platelets were pre-activated by collagen, thrombin, or ADP with sub-threshold level, aggregation was not observed at the test concentration. Microscopic observation also supported the result obtained by the aggregometer.

This study was conducted to evaluate food service satisfaction of senior citizens in three charged silver towns in Gyeonggido. Food satisfaction factors influencing the satisfaction of silver town residents' included satisfaction and word of mouth. For this study, 210 silver town residents were surveyed; however, 16 of these resident did not complete the survey. Therefore, the results of 194 survey questionnaires were analyzed. All results were conducted using the frequency, factor analysis, and regression procedure of SPSS 12.0. The determinant factors of the silver town feeding service included food service, food feeding, emotional, physical, and sensory characteristics of the senior citizens. Among these, food service, food feeding, emotional, and sensory characteristics of the respondents had a significant effect on their level of satisfaction. In addition, satisfaction of the residents was affected by word of mouth. Thus, the results of this study suggests that if the food service is well-arranged by hiring professional workers in the food service industry while considering the needs of senior citizens, feeding service can be improved. In addition, if the feeding service is focused on providing better service with more trained and educated staff members so that the clients perceive that they receive more personalized care and differentiated concern, it would be possible to enhance the relationship with customers continuously and to induce potential customers' residence in the silver town.

이 연구는 노인의료복지서비스의 질적 제고를 위해 노인의료복지시설 소속 종사자들을 대상으로 관리의 변수들 간의 구조적인 관계를 살펴보기 이전에 시설유형에 따른 자기효능감과 직무만족에 대한 요양보호사들의 주관적 인식의 차이를 분석해 보고자 하였다. 실증분석결과 요양보호사들이 근무하는 노인의료복지시설 유형에 따른 인식의 차이는 없었지만 전체적으로 요양보호사들의 자기효능감과 직무만족의 충족이 노인의료서비스 제공에 있어서 중요하다는 것을 강조하였다. 따라서 이 연구는 노인의료복지시설 종사자 관리의 효율화 방안을 위한 이론적 기초를 제공하였다는데 그 의의가 있다.

Alginate-chitosan (anion-cationic polymeric complex) was prepared to control the release rate of silver sulfadiazine (AgSD). Na-alginate (2%) solution containing AgSD was gelled in $CaCl_2$ solution. The gel beads formed were immediately encapsulated with chitosan (CS). The gel matrix and membrane were then reinforced with chondroitin-6-sulfate (Ch6S). Release rate of AgSD from the gel matrix was investigated by placing alginate beads in the sac of cellulose membrane simmered in HEPES-buffer solution. The concentration of AgSD released was analyzed by UV at 264 nm. Incorporation capacity of AgSD in Ca-alginate gel was more than 90%. Alginate-Ch6S-CS could control the release rate of AgSD. The amount of AgSD release was dependent on the AgSD loading dose. Incorporation of tripolyphosphate (polyanionic crosslinker) onto the alginate-Ch6S-CS bead increased the release rate of AgSD. Collagen-coating had no influence on the AgSD release rate. Alginate-Ch6S-CS beads with a sufficiently high AgSD encapsulation were capable of controlling the release of the drug over 10 days. In summary, alginate-Ch6S-CS beads could be used as a sustained delivery for AgSD and provide local targeting with low silver toxicity and patient discomfort.

The purpose of this study is to research on the actual condition of production and selling in silver apparel market. For the questionnaire, 19 women's wear brands which were in higher ranking of sales in boutiques and madame-zone of department stores were selected. Pattern makers of each brand were questioned about 40 items for this research. The results of the questionnaire were as follows: 1) According to the result of the survey on the made-to-wear production of 19 ready-to-wear manufacturers, there was the gap was in ages between the target and the real consumer. Consumers of these brands were older and aged more broadly than their target ages. 2) Most of the consumers of silver-zone has thick waists, common heights, fat shapes. Custom-made clothes are ordered in many cases because of the big abdomen(50.0%) and H-shape(58.3%) of a somatotype. The body size variation of user population is needed for a good fit. 3) All brands(100%) of this research are using KS standards in the label of clothing, but they don't use these data in their production by reason of unawareness and distrust about these data. These inconsistency between the label and the real size of products may cause a confusion when consumers buy ready-to-wear. 4) Silver apparel manufacturers have need of anthropometry information and dummy(78.6%) suitable for their target consumers to increase their satisfaction about their apparel fit.
