  • Background: Multiple Chemical Sensitivity (MCS) is an acquired disease which etiology remains unknown. It is characterized by the development of sensitivity to certain chemical products. Most of the hypotheses formulated to explain the syndrome associate it to a previous exposition to some kind of volatile chemical. University researchers in chemical laboratories suffer a phenomenon of multi-exposition to chemical agents at low concentration during long periods of time although in an irregular form. Many of these chemical agents have similar properties to those suspicious of causing MCS. This article studies the prevalence of MCS in laboratory researchers. Methods: The study group is university researchers in chemical laboratories. The control group was obtained from administrative personnel who work in the same universities and therefore, are not exposed to chemical products from the laboratories, but have the same exposition to the rest of environmental polluting agents from the area and from the buildings of the university. In this study, it is used the Quick Environmental Exposure and Sensitivity Inventory (QEESI) (sensitivity of 92%/specificity of 95%). Results: The results showed that the prevalence of MCS for the university researchers is not related to exposition by inhalation to multiple chemical agents, at low concentration. Conclusions: The results disagree with one of the main etiological hypotheses of MCS, which is based on the existence of hypersensitive people, who presents a response after prolonged expositions to very low concentrations during a long period of time.

  • Neural stem cells (NSCs) can proliferate and differentiate into multiple cell types that constitute the nervous system. NSCs can be derived from developing fetuses, embryonic stem cells, or induced pluripotent stem cells. NSCs provide a good platform to screen drugs for neurodegenerative diseases and also have potential applications in regenerative medicine. Natural products have long been used as compounds to develop new drugs. In this review, natural products that control NSC fate and induce their differentiation into neurons or glia are discussed. These phytochemicals enable promising advances to be made in the treatment of neurodegenerative diseases.

  • This study examines how consumer value and conspicuous consumption tendency influence attitudes and purchase intention toward fashion cause-related marketing products. Survey questionnaires were distributed to 326 women in their 20's to 50's living in Seoul January 2012. The instruments included measurements of consumer value, conspicuous consumption tendency, attitude toward fashion cause-related marketing products, intention to purchase fashion cause-related marketing products, and demographics. Factor analysis, correlations, and multiple regressions were conducted using SPSS 12.0. The results of this research are as follows. Consumer value affected attitude toward fashion cause-related marketing products as well as intention to purchase products. Those with a higher conspicuous consumption tendency showed a higher intention to purchase fashion cause-related marketing products, regardless of attitude toward fashion CRM products. This indicates that and association with famous prestige brands will increase the possibility of success of cause-related marketing products. The research helps establish a marketing strategy to launch new fashion cause-related marketing products by discovering the relationships between consumer consumption patterns and attitudes toward fashion cause-related marketing products.

  • The DISCOVER Project (${\underline{D}}istributed$ ${\underline{I}}nformation$ ${\underline{S}}ervices$ for ${\underline{C}}limate$ and ${\underline{O}}cean$ products and ${\underline{V}}isualizations$ for ${\underline{E}}arth$ ${\underline{R}}esearch$) is a NASA funded Earth Science REASoN project that strives to provide highly accurate, carefully calibrated, long-term climate data records and near-real-time ocean products suitable for the most demanding Earth research applications via easy-to-use display and data access tools. A key element of DISCOVER is the merging of data from the multiple sensors on multiple platforms into geophysical data sets consistent in both time and space. The project is a follow-on to the SSM/I Pathfinder and Passive Microwave ESIP projects which pioneered the simultaneous retrieval of sea surface temperature, surface wind speed, columnar water vapor, cloud liquid water content, and rain rate from SSM/I and TMI observations. The ocean products available through DISCOVER are derived from multi-sensor observations combined into daily products and a consistent multi-decadal climate time series. The DISCOVER team has a strong track record in identifying and removing unexpected sources of systematic error in radiometric measurements, including misspecification of SSM/I pointing geometry, the slightly emissive TMI antenna, and problems with the hot calibration source on AMSR-E. This in-depth experience with inter-calibration is absolutely essential for achieving our objective of merging multi-sensor observations into consistent data sets. Extreme care in satellite inter-calibration and commonality of geophysical algorithms is applied to all sensors. This presentation will introduce the DISCOVER products currently available from the web site, http://www.discover-earth.org and provide examples of the scientific application of both the diurnally corrected optimally interpolated global sea surface temperature product and the 4x-daily global microwave water vapor product.

  • The objectives of this study were to perform a descriptive analysis to characterize and compare the sensory properties of commercial Makgeolli products as well as a cross-cultural comparison of the sensory descriptions of these products between two sensory panels (Korean and Japanese). The samples used in this study were seven different types of Makgeolli, which were commercial products. A total of 10 Korean and 7 Japanese panelists were selected in Korea. Each group was trained, and they identified product attributes and performed descriptive analyses independently. The Korean and Japanese panelists generated 34 and 28 sensory attributes, respectively, to describe appearance, odor/aroma, taste/flavor, texture, and after flavor of the products. There were significant differences among the samples for 24 attributes by Korean and 23 attributes by Japanese panelists. Although there was not a large difference in the number of descriptors between Korean and Japanese panels, the Korean panelists generated more various attributes associated with flavor than the Japanese panelists, and the attributes of Japanese panelists included references to non-food products such as rotten grass. Multiple factor analysis (MFA) was applied to the descriptive analysis data from the Korean and Japanese panels to delineate the associations between Makgeolli samples and their sensory characteristics. Both the Korean and Japanese panels clustered the JRM, JSM, KRM and KSM samples into one group and the CRM and BSM samples into another group. The ESM sample was distinguished from the other six samples. These results of the cross-cultural comparison suggest that comparative analyses of sensory profiles between cultures should be conducted regularly in future studies, and further research such as consumer acceptance tests should be conducted to determine the sensory characteristics that drive consumer acceptance of Makgeolli products in the context of increasing food product exports to other countries.

  • The purpose of this study was to investigate the adolescents' images and preference on cultural products based on Baekje traditional culture focused on adolescents. The subjects were 421 adolescents in Daejeon and Chungnam province. The measuring instruments was stimuli of cultural products and a questionnaire with semantic differential scales of image of cultural products, preference, product evaluation criteria, and subjects' demographics characteristics. The data were analyzed by Cronbach's ${\alpha}$, factor analysis, t-test, ANOVA, Duncan's multiple range test, and regression analysis using SPSS program. The results were as follows. First, 3 factors(attractiveness, interest, gentleness) were emerged on images of cultural products based on Baekje tradition culture, however, the current products could not convey affectively the attractive and gentle image of baekje traditional culture. Second, the preference of the Baekje cultural products was evaluated low, and especially design and price was rated low in the evaluation criteria. Third, preference was related with the 3 image factors, and attractiveness factor was showed highly positive effects on preference of cultural products. The implication of this study was to provide the useful cultural product development plan for adolescents, and the research results suggested that modern and individual design, unique traditional pattern, resonable price, and practicality have to be considered to develop successful cultural products for adolescents.

  • This study aims to identify factors affecting the purchase of Korean IT products in overseas markets. The empirical investigation on Chinese and Japanese, which are major overseas markets of Korean IT products and within Korean wave of influence, ascertains that they have had experiences in purchasing Korean IT products such as MP3, hand held phone, and digital camera. In addition, it was revealed that the country image of Korea and valuation of Korean IT products have been enhanced by Korean wave. The result of multiple regression analysis shows that the purchase of Korean IT products is dependent upon social influence, country image, product attributes, preference on Korean wave, and cultural influence. In the separated hypotheses test of China and Japan, the same factors are found to be significant variables affecting the purchase of Korean IT products but practicality, innovativeness, and norms of consumers are found to be significant only in Chinese market. These results imply what should be considered to expedite the export of Korean IT products. In particular, this study finds different factors affecting the purchase of Korean IT products in different countries.

  • The purpose of this study was to analyze consumer recognition, perceived importance, and satisfaction to create a new apple processed product and to promote its consumption. Data were collected from 527 men and women living throughout Korea through a self-administrated questionnaire. Frequencies, one-way analysis of variance, and Duncan's multiple range were conducted using SPSS v. 17.0 software. Recognition of juice and drinks, milk and dairy products, apple jam, and seasoning was high, while that of the other products was low. Consumer perceived importance of products was higher than consumer satisfaction of products. Quality preservation attributes were sanitation, taste, flavor, place of origin, and convenience of purchase. Attributes for improved consumer post-purchase satisfaction after purchasing were content of apple, quality of apple, price, and certificate of quality. The attributes of content of apple and certificate of quality were statistically different by consumer age.
