Winter outerwear includes various clothes such as classical jackets/coats, padded jackets/coats, wind breakers, leather and fur jackets/coats. This research surveyed care-label instructions attached to 100 jackets/coats dropped off at five drycleaners in the Gyungin area. University students' perception and attitudes towards care labels and management of winter outerwear were examined using a questionnaire. Data collected from 230 respondents were analyzed by frequency analyses, t-tests, ANOVAs and Duncan tests with PASW 20.0. Half of the padding jackets/coats were labelled to be dry cleaned and dry cleaning was more excessively labelled than necessary. University students confirmed more care symbols than fiber compositions such as more at time of cleaning than at purchasing. Clothing-related major students understood care label symbols better than non-clothing major students. Consumers laundered some winter outerwear at home, even though they thought dry cleaning was a proper cleaning method. The appropriate cleaning method for padded jackets/coats is laundering; however, consumers who answered dry cleaning as an appropriate method were three times as those who answered washing, and those performed dry cleaning were two times as those who performed washing. Winter outerwear manufacturers should provide adequate and more specified care-information to consumers in order to maintain initial appearance and performance over longer periods.

The common causes of organic mitral regurgitation (MR) include mitral valve prolapse (MVP) syndrome, rheumatic heart disease, and endocarditis. MR also occurs secondary to dilated cardiomyopathy and coronary artery disease. In acute severe MR, the hemodynamic overload often cannot be tolerated, and mitral valve repair or replacement must be performed immediately. We report herein a case of severe MR due to coronary vasospasm that was confirmed via ergonovine echocardiography in a 70-year-old man. He was scheduled to undergo mitral valve surgery, but it did not push through and he was put on medical therapy.

This study evaluate the effect of laundering on the deformation of knitted spandex/cotton fabrics compared with that of knitted cotton fabrics. Commercial knitted spandex/cotton and knitted cotton fabrics for T-shits were laundered in a drum-type washing machine and dried in a tumble dryer. Wale spirality, shrinkage, elastic recovery and surface contour of knitted fabrics were investigated under different laundering conditions: washing temperature, presoaking time and washing cycles. Knitted spandex/cotton fabrics had a lower angle of spirality than knitted cotton fabrics. After the first washing cycle, the angles of spirality of all the fabrics had decreased greatly. Knitted cotton fabric of low density deformed more than that of higher density. Knitted spandex/cotton. fabric of low density shrank less, because of the greater extension given during heat-set. Permanent elongation length at the 80$\%$ extension was longer than at the 50$\%$ extension, and the knitted spandex/cotton fabric which was expanded greatly during heat-set had a lower elastic recovery rate. The surface appearance of the knitted spandex/cotton fabrics was worsl~ than that of the knitted cotton fabrics before laundering and after repeated laundering, because of the much protruded cotton fibers from the yarns.

In recent years, greatly increased incidences of diseases made people more concerned about their hygienic environment. Since clothes are the closest environment to man, many methods have beef proposed to impart antimicrobial properties to the textiles. Benefits associated with incorporating antimicrobial properties in textiles include protection to the wearer from microbiological attack, and prevention of odor from perspiration. Silver has been known to kill 650 different disease organisms, however, nano-sized silver particles are known as skin friendly and does not cause skin irritation. In this study, we have examined the antimicrobial effects of cotton or polyester fabric, on which nano-sized silver particles were treated. Colloidal silver solution made by electrolysis of $99.9\%$ silver stick was more effective than that by reduction of $AgNO_3.\;0.7\%$ concentration of colloidal silver solution by electrolysis is helpful to give reduction of $99.9\%$ S. aureus and K. pneumoniae on a cotton fabric without the decrease of whiteness. Since the structures of fiber and fabric effect on their antimicrobial property, PET filament fabric didn't have sufficient antimicrobial properly. The fabrics treated with up to $5\%$ colloidal silver solution didn't have the properly of antistatic and electromagnetic shield.

We examined dyeing properties using cotton, Tencel, general nylon 66 and hollow nylon 66 treated with aqueous and ethanol extracts without mordant. The antimicrobial properties of fabrics treated with Artemisia extracts against gram positive Staphylococcus aureus (S. aureus) and gram negative Klebsiella pneumonia (K. pneumonia) were also examined. The dying solution concentrations were determined from a calibration curve of the concentration and absorbance of Artemisia extracts. FTIR spectra confirmed that antimicrobial components and colorants (such as 1,8-cineol, thujone, caffeoylquinic acid and chlorophyll) were more present in ethanol extract than in aqueous extract. Nylons had higher $a^*$ and $b^*$, and lower $L^*$ values than cellulose fabrics dyed with aqueous solutions of Artemisia extracts; however, the dyed nylon fabrics were brown. Fabrics dyed with ethanol-extract added solutions were greener and had higher antimicrobial properties than those dyed with aqueous solutions; however, they faded and lost their antimicrobial properties after laundering. Fabrics regained their antimicrobial properties (especially against S. aureus) by the spraying of Artemisia ethanol extract; therefore, the application of Artemisia ethanol extract onto underwear is expected to relieve atopic dermatitis.

Both in Korea and internationally, many know and appreciate Daesoon Jinrihoe for its social work in the three main areas of education, social welfare and health care, and charity aid. The article surveys Daesoon Jinrihoe's activities in these three areas and proposes a comparison with the charitable and ecological work performed by the Taiwanese Buddhist charity (and new religious movement) Tzu Chi, the peace activities of Soka Gakkai, and the projects developed in Bhutan to implement the policy of Gross National Happiness. Tzu Chi is mostly known for its massive recycling activities, but in fact its view of charity and ecology is based on a specific Buddhist theology. Soka Gakkai's vision of peace relates to its interpretation of Nichiren Buddhism. Gross National Happiness in Bhutan is a project promoted by the government, but scholars who have studied it have concluded that it is deeply rooted in Drukpa Kagyu, the dominant school in Bhutanese Buddhism. Similarities are noted, as well as differences with the Western Christian and post-Christian approach to charity, which is largely based on an affirmation of the self. Daesoon Jinrihoe's social work shares with the Buddhist cases studied in the article the idea that the self may deceive (self-deception) but appears to be inspired by the unique principle of Sangsaeng, and by the idea that the root causes of social problems are grievances accumulated through thousands of years and in need of being resolved.

Existing reinforced concrete (RC) frame buildings have seismic vulnerabilities because of seismically deficient details. In particular, since cumulative damage caused by successive earthquakes causes serious damage, repair/retrofit rehabilitation studies for successive earthquakes are needed. This study investigates the repair effect of fiber-reinforced polymer jacketing system for the seismically-vulnerable building structures under successive earthquakes. The repair modeling method developed and validated from the previous study was implemented to the building models. Additionally, the main parameters of the FRP jacketing system were selected as the number of FRP layers associated with the confinement effects and the installation location. To define the repair effects of the FRP jacketing system with the main parameters, this study conducted nonlinear time-history analyses for the building structural models with the various repairing scenarios. Based on this investigation, the repair effects of the damaged building structures were significantly affected by the damage levels induced from the mainshocks regardless of the retrofit scenarios.

Using green tea(GT), oolong tea(OT), black tea(BT) and green tea bag(GTB) out of tea products in market, this study quantified polyphenol and catechins as anti-oxidant substances and analyzed their respective anti-oxidant capacities. As a result, more epigallocathechin(EGC) was found in GT and GTB as well as caffein(CAF) in GT and BT. GT contained more epigallocathechin gallate(EGCG) than other tea types. Both FRAP and ORAC, as two methods of analyzing anti-oxidant capacities, showed that GTB had highest anti-oxidant capacities, while OT had lowest of all. By brand, it was found that all the 3 brands of GT had similarly high anti-oxidant capacities, but there were differences in the anti-oxidant activities of GTB and BT depending on brand. Out of catechin components, it was found that epicatechin(EC), epicathechin gallate(ECG) and EGCG were major components affecting anti-oxidant capacities.
