Resveratrol (trans-3,5,4'-trihydroxystilbene), a phenolic substance present in both grapes and wines, has been reported to have certain pharmacological effects. Using an ethylacetate-phase extraction followed by a high performance liquid chromatographic analysis, the concentration of trans-resveratrol was measured in 9 red wines commercially available in Korea, including the Korean red wine (Noul). Noul red wine with a 1998 vintage had a trans-resveratrol concentration of 3.3 ㎎/l, which was rather higher than the concentrations found in other wines (0.19-2.45 ㎎/l) with the exception of the French wine, J. P. Chenet (3.39 ㎎/l). In addition, the grapes of Vitis labrusca cv. Sheridan cultivated in the Kyungsan area showed a trans-resveratrol content of 6.4 ㎎/㎏.

Purpose - This study aims to investigate domestic wine consumption behavior and make future sales strategies and marketing plans. Research design, data, and methodology - To achieve the purpose of the study, the surveys were conducted targeting 350 wine customers in Jeju and Seoul. 331 responses were collected, and out of them, 21 responses were deleted because they lacked the proper information fill in. A descriptive statistical analysis was applied to the remaining 310 responses. The statistical techniques used for carrying out hypothesis-testing are EFA_(exploratory factor analysis), multiple-regression analysis, and moderating effect in SPSS 18.0. Results - The results indicate that fashion oriented, sociality aspiration and rationality seeking lifestyles had significant influence upon internal attributes. However, well-being oriented and having enjoyment oriented lifestyle had no significant influence upon internal attributes. Furthermore, all the types of lifestyles except social aspiration lifestyles had a positive influence upon external attributes, whereas internal or external attributes had positive influence on customer satisfaction. Conclusions - The consumers who experienced wine purchases think wine selection attributes differ before and after experiencing wine drinking, and it shows that the circumstantial variables as purchase situations prove to be important predicted variables in the behavior field of wine consumers. It implies appropriate wine education according to the consuming trend about wine for wine consumers are needed.

The purpose of this study was to analyze the effects of quality factors on value, satisfaction and loyalty in a wine training program. The results of this study can be summarized as follows: Structural verification of the wine training program loyalty model showed that the quality of the wine training program positively affected both value (p<0.001) and satisfaction (p<0.001). Further, the value of the wine training program positively affected satisfaction (p<0.01), which in turn positively influenced loyalty (p<0.001). The quality of the wine training program was presented as solicitude for students, textbook and curriculum, qualification and confidence of lecturer and staff, and training quality, whereas the value of the program was composed of sense of belonging, promotion of self-esteem, good impression on others, and improvement of social status. Therefore, the wine training institute's intensive management of the quality and value of the program could induce students' loyalty by enhancing satisfaction for the wine training program.

이 연구는 세계와 한국의 포도 생산 및 와인 산업을 살펴본 후, 강원도 영월 지역을 대상으로 하여 와인테마마을조성의 가능성을 알아보고자 한다. 한국은 1988년 수입와인시장이 형성되고 2011년 후에는 국산와인의 시장점유율이 소멸하는 것으로 전망된다. 한국의 와인시장이 외국산 와인의 수입국으로 전락하지 않고 와인 시장이 균형적으로 발전하기 위해서는 수입와인과 경쟁할 수 있는 전략이 요구된다. 이러한 전략의 하나가 그린튜어리즘인 와인 테마마을의 조성이다. 강원도 영월군 거운리 일대는 동강 지류를 따라 펜션과 래프팅 사업체가 집중하고 있어 관광객의 왕래가 빈번하다. 이들이 거운리 일대에 생산된 포도 품종으로 와인을 생산하여 음용하는 와인테마마을 성공가능성은 포도의 계절별 특수성을 고려한 다양한 체험 프로그램에 달여 있다. 포도의 출하 시기인 8월 하순$\sim$9월 하순에는 포도 따기를 비롯한 와인담기 체험프로그램을 운영하고, 포도 관련 직접체험을 할 수 없는 시기에는 영월 지역의 상징인 천문대와 동강의 이미지를 접목시킨 '와인과 시낭송', '와인과 별과 음악회', '영월 와인 영화제', '와인 박물관' 등 도시민들에게 언급될 수 있는 문화적 차원에서의 와인프로그램을 운영하도록 한다. 또한 생식용 캠벨 이외에 머루, 복분자 등 재배작물을 다원화하고 이들 품종으로 만든 와인으로 프랑스 등의 와인 맛에 길들여진 소비자의 입맛을 바꾸게 되면 4계절 와인테마마을의 조성이 가하다고 본다. 한국의 포도주산지인 충청북도 영동군과 경상북도 김천시도 연중 방문객을 모을 수 있는 프로그램을 운영하여 테마마을 조성이 성공을 거두게 되면 이들은 영월군과 함께 한국의 와인산업을 이끌어 갈 수 있게 된다.

Background: AD-2 (20(R)-dammarane-3b, 12b, 20, 25-tetrol; 25-OH-PPD) is a ginsenoside and isolated from Panax ginseng, showing anticancer activity against extensive human cancer cell lines. In this study, effects and mechanisms of 1C ((20R)-3b-O-(L-alanyl)-dammarane-12b, 20, 25-triol), a modified version of AD-2, were evaluated for its development as a novel anticancer drug. Methods: MTT assay was performed to evaluate cell cytotoxic activity. Cell cycle and levels of reactive oxygen species (ROS) were determined using flow cytometry analysis. Western blotting was employed to analyze signaling pathways. Results: 1C concentration-dependently reduces prostate cancer cell viability without affecting normal human gastric epithelial cell line-1 viability. In LNCaP prostate cancer cells, 1C triggered apoptosis via Bcl-2 family-mediated mitochondria pathway, downregulated expression of mouse double minute 2, upregulated expression of p53 and stimulated ROS production. ROS scavenger, N-acetylcysteine, can attenuate 1C-induced apoptosis. 1C also inhibited the proliferation of LNCaP cells through inhibition on $Wnt/{\beta}-catenin$ signaling pathway. Conclusion: 1C shows obvious anticancer activity based on inducing cell apoptosis by Bcl-2 family-mediated mitochondria pathway and ROS production, inhibiting $Wnt/{\beta}-catenin$ signaling pathway. These findings demonstrate that 1C may provide leads as a potential agent for cancer therapy.

Over the last few years, rural areas in northeastern Mexico have present significant changes in social, economic, and territorial aspects linked to the New Rurality. In this context, winemaking has become one of the most dynamic and growing activities in the regional economy. This emerging development has prompted different forms of appropriation and use of this space, but it also highlights the lack of access to knowledge for wine production due to the lack of formal educational centers. As a result, learning communities enable the development of skills and competencies through non-formal educational practices. The objective of this paper is to analyze the role of learning communities in non-formal educational environments, taking as a case study: a collective of small-scale wine producers in Parras de la Fuente, Coahuila. This research focuses on two perspectives of learning: appropriation and technology transfer, and promotion of Mexican wine culture. The main finding was to demonstrate the importance of including educational processes that respond to the context and needs of the community.

This study aimed to elucidate the relationship between the selection attributes and visit motivations of Ningxia wineries and tourist satisfaction and intention to revisit. Utilizing multiple linear regression and simple linear regression models, the study quantitatively analyzed tourists' selection attributes and visit motivations for Ningxia wineries. Factor analysis categorized 12 visit motivation variables into four factors: 'Sensation', 'Educational', 'Companion-Friendly', and 'Experiential'. Additionally, 17 selection attribute variables were classified into four factors: 'Service Quality', 'Environmental', 'Facility', and 'Economic'. Through analyzing the impact of visit motivations on satisfaction and revisit intentions, we have identified the pivotal factors as 'Wine Cultural Education', 'Enhanced Companion-Friendliness', and 'Wine Cultural Experience'. In the analysis of the relationship between selection attributes and revisit intentions, crucial elements involve 'Service Quality provided by the winery"'and 'Environmental of the winery'. Conversely, key influencing revisit intentions include 'Environmental of the winery' and 'Costs and Pricing associated with winery visits'. To ensure the sustainable development of the Ningxia winery industry and promote the enduring growth of rural economies, wineries should place greater emphasis on cultivating wine cultural experiences, artisanal activities, and other project endeavors.
