This study explored the relationship between Generation MZ female consumers' participation in sports activity, consumption of body-exposing sportswear, body-esteem, and appearance management behavior. In-depth interviews were conducted with twenty Generation MZ female consumers who regularly participate in sports activity and consume body-exposing sportswear. Based on transcriptions of in-depth interviews conducted with research subjects, the researcher and two assistant researchers collectively categorized and compared common characteristics found in their responses, categorized according to themes using units of words/terms and paragraphs. The main finding were as follows. Firstly, Generation MZ female consumers participated in various sports activities for an average of approximately one hour, three times per week. The effects of such participation were improvements in physical and psychological health. Secondly, Generation MZ female consumers considered aesthetical, functional, and economical factors when they consumed body-exposing sportswear, regardless of the activity in which they participated. This sportswear served to increase the efficiency of exercise and also played a motivational role. Thirdly, the overall body-esteem of Generation MZ female consumers who participated in sports activity regularly and consumed body-exposing sportswear was high. Fourthly, Generation MZ female consumers who regularly participated in sports activity and consumed body-exposing sportswear were practicing active appearance management behavior in order to show how their body had been shaped by sports activity. In addition, they were pursuing four self-images: "polished image pursue", "self-care image pursue", "natural image pursue", and "trustworthy image pursue".

The purpose of this study is to find out the tendency of the new generation’s consumer roles and green consumption behavior for the environmental conservation. This study is also to reveal some fundamental information for an environmental education program which si able to support the new generation consumers to participate voluntarily in an environmental activity. The 500 subjects of this study were selected from the new generation consumers who wre residing in Seoul, 1998. The 414 data wre finally analyzed by Mean, t-Test, ANOVA, and Multiple Regression Analysis. The major findings were as follows: 1) the purchasing roles of the new generation consumer tended to be higher than the citizen participation’s roles. The variables with the higher score for the new generation’s green consumption behavior were in the rank of the isolation of environmental waste, the purchasing behavior of green product, the recycling environmental resource, and citizen’s participating roles in environmental activity. 2) the new generation’s consumer roles showed a significant differences, according to variables for the environmental value, environmental education, and participation of the environmental and societal activity 3) the green consumption behavior for the new generation consumers showed a significant differences, according to sex, environmental value, participation of the environmental and societal activity. 4) the most influential variables for the green consumption behavior of the new generation consumers were in the rank of consumer roles, educational values, and the participation of the environmental activity. As we see above, the consumer education for the new generations needs to focus on consumer’s roles that let them participate voluntarily in environmental and societal activity, as well as practice positively to use green environmental products whenever they select some items in the markets.

Baicalin is a flavonoid purified from the medicinal plant Scutellaria baicalensis. It has been reported that baicalin exhibits antibacterial, anti-inflammatory and analgesic effects. The present study was undertaken to determine the underlying cellular mechanisms of baicalin action in preosteoclasts. The effects of this flavonoid on preosteoclasts were determined by measuring osteoclast generation and osteoclast activity in macrophage-colony stimulating factor (M-CSF)-dependent bone marrow cells (MDBMCs) and in co-cultures of MDBMCs and osteoblasts. Osteoclast generation was assayed by measuring the number of tartrateresistant acid phosphatase (TRAP) (+) multinucleated cells after culture. Osteoclast activity was assayed by measuring the area of the resorption pit after culture. We found that osteoclast generation was induced by M-CSF and receptor activator of NF-kB ligand (RANKL), and by the 1.25-dihydroxycholecalciferol in our cultures. Baicalin decreased both osteoclast generation and activity in MDBM cultures and co-cultures indicating that it may inhibit bone resorption.

Since reactive oxygen species (ROS) and hydroxyl radicals ($^-OH$) play an important role in the pathogenesis of many human degenerative diseases, much attention has focused on the development of safe and effective antioxidants. Preliminary experiments have revealed that the methanol (MeOH) extract of the stem of Prunus davidiana exerts inhibitory/scavenging activities on 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radicals, total ROS and peroxynitrites ($ONOO^-$). In the present study, the antioxidant activities of this MeOH extract and the organic solvent-soluble fractions, dichloromethane (CH$_2$Cl$_2$), ethyl acetate (EtOAc), and n-butanol (n-BuOH), and the water layer of P. davidiana stem were evaluated for the potential to inhibit $^-OH$ and total ROS generation in kidney homogenates using 2',7'-dichlorodihydrofluorescein diacetate (DCHF-DA), and for the potential to scavenge authentic $ONOO^-$. We also evaluated the inhibitory activity of seven flavonoids isolated from P. davidiana stem, kaempferol, kaempferol 7-Ο-$\beta$-D-glucoside, (+)-catechin, dihydrokaempferol, hesperetin 5-Ο-$\beta$-D-glucoside, naringenin and its 7-Ο-$\beta$-D-glucoside, on the total ROS, $^-OH$ and $ONOO^-$ systems. For the further elucidation of the structure-inhibitory activity relationship of flavonoids on total ROS and 'OH generation, we measured the antioxidant activity of sixteen flavonoids available, including three active flavonoids isolated from P. davidiana, on the total ROS and 'OH systems. We found that the inhibitory activity on total ROS generation increases in strength with more numerous hydroxyl groups on their structures. Also, the presence of an ortho-hydroxyl group, whether on the Aring or S-ring, and a 3-hydroxyl group on the C-ring increased the inhibitory activity on both total ROS and $^-OH$ generation.

It has been known that quercetin, a bioflavonoid widely distributed in fruits and vegetables as dietary-derived flavonoid and exert significant multiple biological effects such as antioxidant and anti-inflammatory, anti-tumor effects. In addition, it has been shown to have a chemoprotective role in cancer, though complex effects on signal transduction involved in cell proliferation and angiogenesis. The present study investigated whether quercetin can enhance antioxidant enzyme activity (glutathione peroxidase: GPx, superoxide dismutase: SOD, catalase: CAT) and regulate the reactive oxygen species (ROS) generation in the presence of vitamin E, L-ascorbic acid, reduced glutathione (GSH) on B16F10 murine melanoma cells. After 48h treatment of cells with quercetin in the presence of vitamin E, L-ascorbic acid, GSH, we measured the cytotoxicities by MTT assay. The cells exhibited a dose-dependent inhibition in their proliferation in the presence of vitamin E, L-ascorbic acid, GSH respectively. We also investigated the effects of antioxidant enzyme activity and ROS generation. The antioxidant enzyme activity of quercetin in the presence of vitamin E was stronger than GSH, L-ascorbic acid, the same treatments decreased ROS generation in B16F10 murine melanoma cells. Taken together, these result demonstrate that the antioxidant effect of quercetin can enhanced in the presence of vitamin E and it might plays an important role in anti-oxidative effects.

The importance of phytoestrogens to human health is currently being actively investigated. Hesperidin, abundantly found in citrus fruits, is known to possess antioxidant, anticancer, and anti-inflammatory effects. Recently, it has been reported that hesperidin inhibits bone loss and decreases serum and hepatic lipids in ovariectomized mice. In our study, to determine the possible role of hesperidin in the regulation of bone metabolism, we observed the effects of hesperidin on the proliferation and activity of osteoblasts, as well as the effects of hesperidin on osteoclast generation and activity. We observed that, when treated with hesperidin, the number and viability of osteoblastic cells increased, alkaline phosphatase (ALP) activity of osteoblastic cells increased, and osteoprotegerin (OPG) secretion from MG63 cells decreased. Hesperidin treatment had no effect on the osteoclast generation and activity in the bone marrow cell culture, but decreased the number and resorptive activity of osteoclasts generated from RAW/264.7 cells. Taken together, these results indicate that hesperidin increases the proliferation and activity of osteoblasts, while inhibiting generation and activity of osteoclasts. Although the precise role of hesperidin remains to be elucidated, our study suggests that it is one of the important modulators of bone metabolism.
