  • The dielectric properties, dielectric constant (${\varepsilon}‘$) and loss factor (${\varepsilon}’$), of skin and pulp of fresh ginseng were measured from $25^{\circ}C$ to $67^{\circ}C$ using an open-ended coaxial probe technique for 915 MHz and 2450 MHz. Pulp and skin had dielectric constant of $30{\sim}64$ and loss factor between 10 and 20, each variable having a respective frequency dependence typical of materials with high water content. Although the loss factor was nearly constant, the dielectric constant increased as moisture content increased. The dielectric constant of ginseng pulp increased as temperature increased (temperature ${\leq}56^{\circ}C$), but any significant differences were not found in skin dielectric properties. Penetration depth for fresh ginseng were about 2 cm at 91.5 MHz and 1cm at 2450 MHz.

  • Fetal bovine serum (FBS), which contains various nutrients, comprises 20% of the growth medium for cell-cultivated meat. However, ethical, cost, and scientific issues, necesitates identification of alternatives. In this study, we investigated commercially manufactured serum-free media capable of culturing Hanwoo satellite cells (HWSCs) to identify constituent proliferation enhancing factors. Six different serum-free media were selected, and the HWSC proliferation rates in these serum-free media were compared with that of control medium supplemented with 20% FBS. Among the six media, cell proliferation rates were higher only in StemFlexTM Medium (SF) and Mesenchymal Stem Cell Growth Medium DXF (MS) than in the control medium. SF and MS contain high fibroblast growth factor 2 (FGF2) concentrations, and we found upregulated FGF2 protein expression in cells cultured in SF or MS. Activation of the fibroblast growth factor receptor 1 (FGFR1)-mediated signaling pathway and stimulation of muscle satellite cell proliferation-related factors were confirmed by the presence of related biomarkers (FGFR1, FRS2, Raf1, ERK, p38, Pax7, and MyoD) as indicated by quantitative polymerase chain reaction, western blotting, and immunocytochemistry. Moreover, PD173074, an FGFR1 inhibitor suppressed cell proliferation in SF and MS and downregulated related biomarkers (FGFR1, FRS2, Raf1, and ERK). The promotion of cell proliferation in SF and MS was therefore attributed to FGF2, which indicates that FGFR1 activation in muscle satellite cells may be a target for improving the efficiency of cell-cultivated meat production.

  • This study investigated the effect of a coaching system(CS) on the employee's job satisfaction(JS) between the food service industry conducting and not conducting CS. A total of 342 employees were enrolled and the results were as follow. Firstly, relationship and willingness factors directly affected JS. Indirectly, work and relationship factors affected JS through the willingness factors. Secondly, when JS was compared at the service company conducting CS with that not conducting CS, work and relationship factors directly affected JS in the industry conducting CS, but only the relationship factor indirectly affected JS in the company not conducting CS. In addition, at the food service industry conducting CS, work factor affected willingness and competence factors, and therefore JS was affected indirectly, but relationship factor did not affect the willingness and competence factors. However, in the company not conducting CS, willingness only affected JS indirectly. Work factors directly affected JS, but through competence and willingness factors, work factor indirectly affected JS in the industry conducting CS. In the company not conducting CS, the relationship factor between employees affected the JS. In summary, CS increased JS through its direct effect on the work factor and indirect effect on the willingness and competence factors. Studies about CS are insufficient and CS remains in the introductory stage now, so further studies are necessary.

  • This study examined the possible causes of nutritional inadequacy in Vietnamese immigrant women married to Korean husbands. Qualitative in-depth interviews were conducted with a sample of 34 Vietnamese marriage immigrant women and 17 Korean spouses participating in or having experienced Nutrition Plus from four Community Health Centers in Seoul, Korea. The study results showed that the nutritional staus of the Vietnamese marriage immigrant women was affected by the unfamiliar Korean food (cultural factor), low household income (economical factor), difficulty in purchasing Vietnamese food (environmental factor), and low accessibility to nutrition support systems (social factor). The Korean husbands' nutritional status was affected by the unfamiliar Vietnamese food (cultural factor), low household income (economic factor), and irregular working conditions (social factors). Nutritional interventions as a public service to the community needs to be developed and applied. Suggestions are presented regarding the future efforts to better understand and meet the nutrition needs of intermarried couples to respond to their heterogeneous needs and deliver adequate nutrition service to ever increasing intermarried families.

  • The purpose of this study was to determine the relationship between conspicuous consumption tendency, brand attitudes, and purchase intentions of college students regarding eating out by limiting conspicuous consumption tendency among several psychological variables to acquire a more precise and concrete influence factor on consumption behavior to eat out. First, as for sensing other people, pursuing individuality and brand orientation among conspicuous consumption tendency of restaurant costumers had significant effects on brand attitudes, whereas the influence of status symbols and pursuing trend factor on brand attitudes was not verified. Second, as for sensing other people, pursing individuality, pursuing trends, and brand orientation factor among conspicuous consumption tendency had significant effects on purchasing intention. Otherwise, the significant effect relationship between status symbols factor and purchasing intentions was not confirmed. Third, as purchase intentions increased, brand attitudes of consumers increased according to existing research. Thus, this study suggests a more departmentalized marketing strategy method to create profits and enhance competitiveness of food service enterprises, and academic implications suggest fundamental data of relevant studies on conspicuous consumption tendency and purchasing behavior of consumers to eat out.

  • The purpose of this study was to investigate purchasing variables in the organic food consumption level in Busan. To achieve this purpose, 240 residential women who are organic food consumers were chosen. Among them, 149 women took part in the study. The questionnaire was composed of three parts: 8 demographic characteristics, 9 organic food purchasing conditions, and 22 purchasing variables. The research was continued from August 20th until September 10th, 2007. To derive the results, descriptive analysis, factor analysis, and ANOVA were used by spss 14.0. To sum up the results, three organic food consumption groups were classified into high, middle, and low consumption levels depending on buying condition for organic material. For the factor analysis, 5 factors were named as confidence, quality, safety, appearance, and economy. On the high consumption level, economy factor was highly important than other groups. In general, price would be a more sensitive factor, so they answered the adjusted price range; 52 participants said under 10%, 22 between 11% and 20%, and 17 over 40%.
