The purpose of this study was to investigate dining-out behavior at ethnic restaurants and its relationship with ethnic restaurant satisfaction based on the food-related lifestyle (FRL) of undergraduate students. A total 306 of questionnaires were analyzed using SPSS ver. 12.0 package. The data were analysed using frequency, chi-square, one-way ANOVA, factor analysis and multiple regression analysis. According to the results of factor analysis, the FRL of undergraduate students categorized into health factor, taste factor, convenience factor and ethnic restaurant satisfaction was influenced by four elements: service & hygiene, food quality & convenience, atmosphere & image and unique culture. In addition, visiting frequency and visiting motivation of all dining-out behaviors at ethnic restaurants were significantly different and the FRL groups had differences in the influence of food quality & convenience, atmosphere & image and unique culture. Futhermore, the health factor of FRL was influenced by all elements of ethnic restaurant satisfaction. The findings indicate that ethnic restaurant owners should provide food with healthy ingredients in addition to unique culture and atmosphere to customers.

Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a multifunctional cytokine that has been implicated in the regulation of pre-implantation embryo development across several species. The aim of this study was to determine the effects of mouse granulocyte-macrophage colony-stimulating factor (mGM-CSF) on development of porcine parthenotes and nuclear transferred embryos, and on their expression of implantation-related genes. In the presence of bovine serum albumin, mGM-CSF did not increase the percentage of oocytes that developed to the blastocyst stage and at day 7 did not increase oocyte cell number. Addition of 10 mM GM-CSF to protein-free culture medium significantly increased the compaction and blastocoel formation of 1- to 2-cell parthenotes and cloned embryos developing in vitro. However, cell number was not increased when they were cultured in the presence of GM-CSF. Semi-quantitative reverse transcripts polymerase chain reaction (RT-PCR) revealed that mGM-CSF enhances mRNA expression of the leukemia inhibitory factor receptor, but does not influence interleukin-6 or sodium/glucose co-transporter protein gene expression in blastocyst stage parthenotes. These results suggest that mGM-CSF may enhance viability of porcine embryos developing in vitro in a defined culture medium.

This study utilized importance and performance analysis (IPA) in order to improve and plan tangible (menu) and intangible (service) products at dumpling shops. Menu attributes for tangible products were classified into sensory factor, health factor, hygiene factor, and external factor. Attributes for intangible products were classified into response factor, visual factor, spatial factor, package factor, and promotion factor. In IPA analysis of tangible products, sensory factor and hygiene factor were located in Quadrant I (Keep up the good work). Health factor was located in Quadrant III (Low priority for management) and the external factor was located in Quadrant II (Possible overkill). In IPA analysis of intangible products, response factor and visual factor were located in Quadrant I, whereas promotion factor was located in Quadrant III. The attributes related to kindness of staff and space for customers in the store were more important, but due to their low performance level, they were located in Quadrant IV (Concentrate management here). Thus, the product planner should improve attributes of the related product immediately. As a result, the development of competitive products within the market is possible.

The purposes of this study was to examine the college students'value and the status of their clothing purchasing behavior, and to compare the correlation between both of them. The questions were centered on 511 students who are attending the universities in Seoul. The results of this study were as follows. First, most students have higher value on politics, economy, and theory in the order listed. Male-students were interested in theory, while female-students were more interested in politics. Second, when they purchase their clothes, the factor of decision was based on design and their observation was another important factor. As for selecting shops, they considered the product as the most important factor and then the service & transportation. Third, I inspected the correlation between their value & the status of their clothing purchasing behavior. The students with lower theoretical value considered the quality as a purchasing factor, and the service as a purchasing factor, common shop as a purchasing shop, adn the convenient transportation system as a factor of selecting a shop.

Objectives : This study examined the effects of Bee venom on apoptosis in NCI-H157 human lung cancer cells and for promoting the apoptosis effects of Natural killer cell. Methods : Bee venom and Natural killer-92 cells were cultured either separately from or together with NCI-H157 cells for 24 hours. To figure out whether Bee venom enhances the cytotoxic effect of Natural Killer-92 cells, a cell viability assay was conducted. To observe the changes in Death receptors, apoptotic regulatory proteins and Nuclear $Factor-{\kappa}B$, western blot analysis was conducted. To observe the effect of Bee venom through an extrinsic mechanism, a transfection assay was conducted. Results : 1. Natural killer-92 cells and Bee venom significantly inhibited the growth of NCI-H157 cells and co-culture had more inhibitory effect than the separate culture. 2. Expressions of Fas, DR3, DR6, Bax, caspase-3, caspase-8, cleaved caspase-3, cleaved caspase-8 were increased, and expressions of Bcl-2 and cIAP were decreased. More efficacy was observed in co-culture than in separate culture. 3. Nuclear $Factor-{\kappa}B$ activation was clearly decreased. And co-culture showed much less activation than separate culture. 4. As a result of treatment for DR-siRNA, the reduced cell viability of NCI-H157 cells and the activity of Nuclear $Factor-{\kappa}B$ were increased. With this, it can be seen that Bee venom and Natural killer-92 cells have an effect on the cancer cells through the extrinsic mechanism. Conclusion : Bee venom is effective in inhibiting the growth of human lung cancer cells. Furthermore Bee venom effectively enhances the functions of Natural killer cells.
