The purpose of this study is to understand factors of risk perception and purchase obstruction by consumer characteristics and purchase experience of clothing in online. The collection of the research materials was progressed by online and offline. Out of 374 usable questionnaires used for examining this study, 278 questionnaires were collected from offline and 107 questionnaires were collected from online. Frequency analysis, factor analysis, reliability analysis, t-test, One-way ANOVA and multiple regression analysis using SPSS WIN 12.0 were conducted. Three factors of perceived risk were extracted: harmonic/image, quality/shopping process, payments. Based on these dimensions, ANOVA was conducted. The results indicated that the more purchasing experience people had, the less the extent of perceived risk they got, and quality/shopping process risk mostly among them. As the factors which obstruct purchasing decision, a security obstruction, a reliability obstruction, a convenient obstruction and an information insufficient obstruction are extracted. Also, the factors have got the result of same aspects as the perceived risk recognized by the Internet shopping experience. Meaningful differences between groups appear at security obstruction, reliability obstruction, and convenient obstruction. Perceived risk almost influenced on purchase obstruction when purchasing clothes in Internet shopping mall. When consumers perceiving harmony/image risk highly make decisions, they usually hesitate or abandon due to reliability obstruction, convenient obstruction. All the factors: including security obstruction, reliability obstruction, convenient obstruction and information insufficient obstruction made consumers perceiving quality/shopping process risk highly obstruct purchase decision.

Mushrooms have been widely cultivated and consumed as foods and herbal medicines owing to their various biological properties. However, few studies have evaluated the anti-inflammatory effects of mushrooms. Here, we investigated the effects of mushroom extracts (MEs) on lipopolysaccharide (LPS)-induced inflammation in macrophages (RAW264.7 cells). First, we extracted MEs with either water or ethanol. Using LPS-treated RAW264.7 cells, we measured cell proliferation and NO production. Gene expression of tumor necrosis factor-α (TNF-α), interleukin (IL)-6 (IL-6), and IL-1β was assessed by RT-PCR, and protein abundance of inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) and phosphorylation of p65 were determined by immunoblotting. MEs prepared using both water and ethanol inhibited LPS-induced inflammation in RAW264.7 cells. Nitric oxide (NO) levels induced by LPS were reduced by treatment with MEs. Isaria japonica Yasuda water extracts and Umbilicaria esculenta (Miyoshi) Minks ethanol extracts significantly decreased the mRNA expression of inflammation-related cytokine genes including TNF-α, IL-6, and IL-1β. Similarly, the protein abundance of iNOS and COX-2 was also decreased. The phosphorylation of p65, a subunit of nuclear factor-κB was at least partly suppressed by MEs. This study suggests that mushrooms could be included in the diet to prevent and treat macrophage-related chronic immune diseases.

Background : Obesity is a type of metabolic diseases caused by unbalanced in take and consumption of calories. 3T3-L1 is differentiated into adipocytes by various hormones and transcription factors and accumulates intracellular lipid. Therefore, it is important to inhibit the adipocyte differentiation precess for effective obesity inhibition. Aster yomena and Aster glehui are medicinal plant of Compositea family that grows widely in Korea. Aster genus plants have been used to treat snakebite wound or bruises in oriental. The aim of this study was comparison of inhibitory effect oxidation and adipocyte differentiation with Arial parts of A. yomena (AY) and A. glehni (AG). Methods and Results : AY and AG were cultivated from Pyeongchang in Korea, 2018. AY and AG were extracted by 70% ethanol (-E) and water (-W) at room temperature. AG-W has higher phenolic content (6.92 ± 0.23) and AG-E has higher flavonoid content (8.22 ± 0.19) than other extracts. AG-E has higher radical scavenging activity on DPPH and ABTS assay (IC50 value; 104.88 ± 10.50 and 30.06 ± 0.27). In cytotoxity assay, all extracts concentrations of lower 100 ㎍/㎖ were nontoxic to the cells and can be applied for the next assay. The anti-adipogenic effect of extracts were determined in 3T3-L1 cell by Oli Red-O (ORO) staining. The lipid diplot stained with Oil red O was dissolved to determine by microplate-reader. AG-W significantly reduced the adipocyte differentiation of 3T3-L1 cells (70.49%) compared with other extracts (AG-E, AY-W and AY-E). Conclusion : Theses results reveal that the water extract of AG has utility as a functional food material for preventing obesity.

We investigated traditional knowledge about ethnobotanical uses around national parks in the northern areas of Province Gyeongsangbuk-do, with the focus on the Sobeaksan National Park area. Interviews were carried out to 138 residents at 42 places from 7 counties and/or cities, and verified species and usage information were categorized by taxonomic groups, usage, and used parts. The ethnobotanical species of the regions consisted of a total of 277 taxa: 244 species, 3 subspecies, 28 varieties, and 2 forma in 213 genera of 79 families. The significant native plants included one Endangered Species (Paeonia obovata Max.) and four endemic species (Salix hallaisanensis H. Lev., Aconitum pseudolaeve Nakai, Paulownia coreana Uyeki, and Cirsium setidens (Dunn) Nakai, Sasa coreana Nakai). About 17 Approved Species for Delivering Overseas designated by Korea Ministry of Environment have been also traditionally valuable in the regions. The main usage of the plants were edible (185 taxa) and medicinal (175 taxa). Leaves were most commonly used parts (109 taxa), followed by stems (73 taxa), fruits (69 taxa), roots (67 taxa), and wholes (57 taxa). The traditional usage of plants were diverse as those useful parts. Leaves, fruits and seeds were used as edible and medicinal; sprouts (young shoots) were mainly used as edible; but roots and flowers were used as medicinal. The study does not only provides examples of traditional uses of native plants, but also facilitates sustainable managements and developments of ethnobotanical knowledge for the contemporary society.
