The purpose of this study is to investigate the effects of supplementation of mulberry powder, mulberry extract and silkworm powder during the 8 weeks of resistance exercise on Androgen receptor(AR) mRNA and Myogenic regulatory factors(MRFs) expression of rats muscle. Fifty males, Sprague-Dawley rat, were randomly divided into 5 groups: CON(control group, n = 10), REG(resistance exercise group, n = 10), MP REG(mulberry powder intake and resistance exercise group, n = 10), ME REG(mulberry extract intake and resistance exercise group, n = 10) and SP REG(silkworm powder intake and resistance exercise group, n = 10). After climbing the ladder without weights during the 1 week of adaptation period, the rats in the resistance exercise group were trained to climb a 0.98-m vertical(80 degree incline) ladder with weights in their tail during 7 weeks(10 times each day, 2 days per week). After exercise, the skeletal muscle was extracted from the flexor hallucis longus. After separating the total ribonucleic acid (RNA) of each group, quantitative polymerase chain reaction was used to analyze RNA quantitatively. AR mRNA and MRFs expression revealed that all of the treated groups had significantly difference. AR mRNA expression increased in ME REG $6.24{\pm}1.85$ and SP REG $9.68{\pm}0.28$ fold compared to CON. Myod mRNA expression increased in MP REG $6.04{\pm}0.47$, ME REG $4.31{\pm}1.58$ and SP REG $8.11{\pm}0.57$ fold compared to CON. And myogenin mRNA expression increased in MP REG $4.11{\pm}0.42$, ME REG $4.12{\pm}0.45$ and SP REG $6.50{\pm}0.61$ fold compared to CON. In conclusion, during the resistance exercise, providing mulberry and silkworm gives positive effect on AR mRNA and MRFs expression increase.

We investigated the anti-wrinkle activity of an 80% ethanol extract of Curdrania tricuspidata leaves (CTL80) on ultraviolet-induced photoaging in hairless mice. Skin wrinkles were induced by 10 weeks of UVB-irradiation on the back of Skh-1 hairless mice three times a week. Mice were divided into ten groups; normal control (-UVB), UVB irradiated control group (+UVB), dietary groups (UVB+ascorbic acid 0.1%, UVB+CTL80 0.1%, UVB+CTL80 0.25%) and topical application groups (-UVB+base lotion (BL), UVB+BL, UVB+ascorbic acid 1%+BL, UVB+CTL80 1%+BL, UVB+CTL80 2%+BL). Wrinkle formation, histological changes, superoxide dismutase (SOD) activities, glutathione peroxidase (GSH-Px), and the expression of matrix metalloproteinases (MMP-1, MMP-3 and MMP-9) were analyzed. Wrinkles for the +UVB groups formed as a pattern of deep furrows and thick crests. Wrinkles with CTL80 treatment formed as a pattern of shallow furrows and thin crests, with wrinkle areas were lower than the +UVB group. In an antioxidant analysis of mouse blood, SOD and GSH-Px activities were significantly higher in the CTL80 topical application group compared to the +UVB group. The mRNA expression of MMPs in the +UVB group was significantly higher than the normal control group, and significantly lower in the CTL80-treated group. In conclusion, CTL80 exerted anti-wrinkle activity on ultraviolet-induced photoaging by regulating antioxidative defense systems and MMPs expression.

The antioxidant activities and antibacterial activities of grape pomace fermented using a variety of useful microorganisms were analyzed. There were several experimental groups: the control, with non-fermented grape pomace; the BS group, fermented by Bacillus subtilis; the LP group, fermented by Lactobacillus plantarum; the LC group, fermented by L. casei; the CU group, fermented by Candida utilis; the Y1 group, fermented by Saccharomyces cerevisiae strain CHY1011; the Y2 group, fermented by S. cerevisiae strain ZP 541; and the M group, fermented by a mixed strain culture of LP, LC, and CU. The yield of freeze-dried powder of fermented grape pomace by BS, LP, LC, CU, Y1, Y2, and M was 10.74%, 9.36%, 8.68%, 9.55%, 7.49%, 9.60%, and 9.71% w/w, respectively. The total polyphenol content of grape pomace showed the highest value in the control, but the fermented LP had higher total polyphenol content than those of other fermented grape pomace. The control and fermented LP had 0.16 mg/mL and 0.28 mg/mL as $IC_{50}$ values on DPPH radical scavenging, and 0.22 mg/mL and 0.53 mg/mL of ABTS radical scavenging activity, respectively. The FRAP value (5 mg/mL) showed the highest value on fermented LP (2.44 mM) but did not show a significant difference in the control group (12.27 mM). The fermented LC showed the antimicrobial activities against B. cereus (11 mm), B. subtilis (11 mm), Staphylococcus aureus (12 mm), Escherichia coli (12 mm), Enterobacter cloacae (10.5 mm), Salmonella enterica (11.5 mm), and Pseudomonas aerugionsa (11 mm) at 5 mg/disc, but the control and other fermented grape pomace did not show antimicrobial activities. Thus, fermented grape pomace by LC is shown to be producing a material that has antibacterial activity. In conclusion, grape pomace fermentation using various lactic acid bacteria strains showed excellent effects in promoting the production of functional materials. Especially, using L. casei exhibited an increase in antibacterial activity, and using L. plantarum exhibited antioxidant activity.

This study was performed to develop menu satisfaction index in Business & Industry (B&I) food service and to survey customer's menu satisfaction using the index. The menu satisfaction index included 16 items with Likert 5 point. Cronbach's alpha to assess the internal reliability of the developed scales was 0.8917, which indicated highly reliable. Construct validity was assessed by principal components analysis and then four factors explaining 65.964% of the total variance were found. Among the 15 items of menu satisfaction, the average scores of all items were above 3.0 out of 5. As a result of analysis on menu satisfaction factors, 'propriety of food temperature' (3.52 out of 5) was the highest consideration followed by 'sufficiency of format' (3.46), 'excellence in food' (3.35) and 'well-being orientation' (3.31). It could be said that customer's perception on the menu quality was very positive. Four factors were correlated with overall menu satisfaction positively. Especially, 'excellence in food', and 'well-being orientation' and 'sufficiency of format' affected significantly on overall menu satisfaction. It concluded that customers were satisfied with portion size, temperature, price but their needs for taste and health/nutrition-related service would be increased. The menu satisfaction developed in this study should be applied to other B & I food service operation by type.

It is generally regarded a design system in post-industrial society, which products designed by in-house designers or design consultancy are manufactured in factory and distributed in market for the consumer. Although it is treated an old design system in traditional society, the traces of vernacular design has been remaining in the state of adopted to the periodical needs in these days, also proving the attribute of design culture to constitute human's material environment as well as existing design systems. There were discovered various design artifacts in daily surroundings vary from the established design in several manners, user modifications or manufactures in everyday lives formalized them. It was approached a case study that analyze the changes of artifact configuration and designer/user context and creation process of the non-professional design artifacts, Creativity Template Theory and ACM(Artifact Context Model) have been utilized for the analysis model. From the analysis result, It assume that the everyday artifacts may be ordinary but extra-ordinary including particular ideas and identity represented by everyday designers or users. Beside these characteristics induce the potentiality that reflect on creative motives for the designers or a complementary artifact generator filling up with drawbacks in established design system. The everyday design domain, various explorations and alternatives are made, is seems to be another design practice domain dissimilar to the one in the industry-based design. Moreover it provides an more easily accessability for the approaching user-friendly design, user customization because they conduct the reliable modeling of consumer and end-user. Finally, based on the exploratory study regarding interpretation of context and configuration in the everyday artifacts, new approach for the design process and design education through more detailed cognitive modeling of everyday designers will be a further study.

Low molecular peptides were isolated from Asterias amurensis via SDS-PAGE. The peptides were separated via consecutive gel filtration as five fractions (F1-F5) according to molecular weights, based on the results of MALDI-TOF MS analysis. The molecular weight of the most active peptide was estimated as 15,000 daltons. The peptide showed cytotoxicity on normal human fibroblast cells at levels as low as 20% when 1.0 mg/mL of the samples was added. The peptide also exhibited higher levels of nitric oxide production from macrophages than the lipopolysaccaharides. It was determined that prostaglendin $E_2$ production was significantly inhibited, up to 127.8% as compared to the control. The low molecular peptide inhibited hyaluronidase activity as 535.7 ${\mu}g/mL$ of $IC_{50}$. It can be concluded that the relatively low molecular weight peptide, fucoidan, from A. amurensis has excellent cosmetic and immunomodulatory activities, which can be considered as a possible resource of new cosmetic agents for skin immunomodulation.

This study was conducted with the aim of opening a new horizon in understanding the church, which is a community of faith, in the context of losing social credibility with selfishness and closedness, and spreading social distance due to the epidemic. First, the concept and meaning of 'Ecclesia', a representative term for the church, was studied historically, biblically, and theologically, and Paul's intention was frequently used. Second, we explored the new horizons of the community of faith through a discussion of Roberto Esposito's Communitas and Immunitas, which unraveled the relationship between community and individual with an immunological concept. Not only dis lose social trust for a variety of reasons, but it has been pointed out as a target of social distancing due to the spread of the epidemic virus and is facing a crisis of weakening or loss of the faith community of the "church". Since the second epidemic has been predicted since Covid-19, the partial loss of daily life and the weakening and loss of meeting worship and fellowship in the church are inevitable. The church in the future needs to transform and build a true community of faith that understands the concept of immunity and can lead the transformation of society while revealing the spirit and life scent of Jesus Christ. To this end, innovation and practice of the paradigm of the community of faith appropriate to the rapidly changing times and situations is required. In Chapter 1 of this paper, we propose innovation by pointing out the problems of the church and the faith community, which have lost social credibility, and which are the objects of social distance, with selfishness and closedness. Chapter 2 studies and analyzes the 'Ecclesia' used in ancient Greek to transform the paradigm of the faith community, and identifies the intention of the apostle Paul to apply the 'Ecclesia' to the church's faith community. Chapter 3-4 discusses the concept of immunity, summarizes the reinterpretation of Esposito, who looked at the relationship between the individual and the community through the concept of positive immunity beyond negative immunity. And It draws application points for transforming the faith community of various communities, individuals, and churches. In conclusion, Chapter 5 restores precious gatherings and participation that are weakened and lost through the meaning of 'Ecclesia' and suggests expansion to higher level public gatherings and democratic participation. In addition, based on the reinterpretation of the concept of immunity, we present unity in diversity and diversity in unity as alternatives to the church and community of faith.
