  • This research was conducted to investigate changes in quality characteristics of gamma-irradiated porks during storage at different temperature and periods. In The proximate composition of pork was not significantly changed by irradiation dose and storage period. The SDS electrophoresis patterns were not significantly different between nonirradiated and irradiated samples. All samples stored in at 5$^{\circ}C$ showed a prominent breakdown of molecular weights ranging from 97,000 to 116,000 Daltons after 8 weeks' storage. In heme pigment(myoglobin) content, metmyoglobin content of chicken stored at 5$^{\circ}C$ was not affected by gamma irradiation but slightly increased with the increase in storage period. All samples stored at -2$0^{\circ}C$ were not different in heme pigment content between nonirradiated and irradiated samples and slightly decreased as the freezing storage period increased. About textural property, hardness of all samples appears to be increased slightly by gamma irradiation. However, the extent of increase was so little that it could be ignored.

  • The purpose of this study was to determine the desirable mixture ratio of Cirsium setidens Nakai powder to rice flour for the preparation of Sulgidduk. The moisture of samples raged from 36.51% to 40.67%. The addition of Cirsium setidens Nakai powder in the Sulgidduk tended to decrease the lightness (L) in Hunter color value, but to increase the redness (a) and yellowness (b). With increasing Cirsium setidens Nakai powder level, the hardness, springness and chewiness of the samples increased and their cohesiveness decreased. In sensory evaluation, the addition of 5% Cirsium setidens Nakai powder showed the best score in taste and overall preference. Over 3 days of storage, Sulgidduk showed a slightly high total bacterial count compared to control. Therefore, these results suggested that the addition of 5% Cirsium setidens Nakai powder could be applied for making Cirsium setidens Nakai powder Sulgidduk.

  • We desperately recognize from the economic situation in IMF crisis that only competive goods and serviced. It is anticipated that this difficult situation will probably be continued till 1999. Therefore, it is necessary to think over real aspects of eating=outdoors in IMF period and to provide an opportunity to confront with this crisis. Analysis a recent tendency of domestic eating-outdoors business, there appears, first of all, dual types of eating-outdoors; the one is a sort of 'Cost Sale', which provides some special menu with lowest prices, and the other is a type of 'Family Restaurant', which regards the atmosphere of the place as one of the most essential elements. Both types are getting more popular today. As the result, neither of the alternative cannot recover the current Depression. It is natural that no other conditions can compete with good tastes, fancy atmosphere, and good prices. As a matter of fact, however, it is quite difficult to run this type of bussiness adjusted the above whole conditions. Therefore owners of eating-house must decide to run either ' Cost Sale' or 'Family Restaurant' first and investigate some problems and conditions accordingly. In ane way, the owner intensively visits to some eating houses which is similar style in size and management to that of his style in size and management to that of his and look over what is good and what is bad Right after this investigation, it is efficient for he or she to improve his or her business style in size and management in a short period. It is helpful to check some complements; improvement of signboards, cleaning up of the interior, selecting suitable menu, adjusted prices, tastes, and service quality etc. Although eating-outdoors business is hard hit by IMF, We hope that it would rapidly be brisk in 2000, becaused by that time the basis of each industry would be high qualified, and rich technology would be accumulated.

  • This study aims to investigate the effect of core-self evaluation on work-family facilitation(work to family facilitation, family to work facilitation), job satisfaction and turnover intention among non-regular workers in Korean food service industry. In order to examine the hypothesized relationships, frequency analysis, confirmatory factor analysis, reliability analysis, correlation analysis and covariance structure analysis were performed using SPSS(10.0) and AMOS(4.0). The results showed that core-self evaluation had a significantly positive effect on both of work to family facilitation and family to work facilitation. In the case of relationship between work-family facilitation and job satisfaction, only family to work facilitation had a positive effect on job satisfaction while there was no evidence of a significant relationship from work to family facilitation to job satisfaction. Additionally, job satisfaction had a significantly negative effect on turnover intention. The article concluded with managerial implications for managerial and future research directions.

  • The effects of soaking and steaming time on the quality characteristics of Korean rice cake (karedduk) were investigated. As the soaking time increased, the water-binding capacity and rice floor solid content also increased. After 8 to 10 hr soaking, 75.2 to $76.8\%$ of particles were smaller than $40\;{\mu}m$, and 23.2 to $24.8\%$ within the range of 40 to $100\;{\mu}m$. Therefore, an extended soaking time reduced the particle size. Texture is an important characteristic used to differentiate karedduk varieties, and is considered by the consumer as a determinant of the overall quality and preference. The hardness, cohesiveness, gumminess and chewiness of the karedduk structure decreased with increasing steaming time, but the springiness was highest after a 40 min steaming time. The overall texture properties were also more acceptable with 8 and 10 hrs soaking times. The L value of the karedduk decreased with increasing steaming time, but the b value increased. Also, the results of the sensory evaluation showed that an 8 hr soaking time and 40 min steaming time produced more acceptable karedduk in terms of whiteness, texture, springiness, chewiness and overall acceptability.

  • The properties of various grains used for the solid-state cultivation of basidiomycetes were examined. The hydration time with cold water was 10 hours for malt soybean. The required hydration time for Job's tears, barley and wheat was 4, 6 and 12 hours, respectively, but the final moisture content ranged from 30 to 48 %, which was much less than the optimum moisture content for mycelial growth. For the mass cultivation of mycelia, the hydrated grains with cold water were placed in plastic bottles. The mycelial growth ra in e bottled grains was high in the early stage with inoculation of homogenized mycelium. The mycelium activity was maintained by adding sterilized water in the middle of the cultivation period. Jupjang underwent sensory evaluation to examine the possibility of utilizing basidiomycetes in functional foods. The grains fermented with Ganoderma lucidum was the best for Jupjang. The combination of malt soybean and Job's tears was the best for Jupjang. The acceptability of Jupjang was improved during the period of aging time.

  • The principal objective of this study was to determine the effects of service quality in a Korean restaurant in a Five Star Hotel in Metropolitan city causes on customers satisfaction, revisiting intentions and word of mouth communication. As a component of the study, 344 customers who had visited restaurants at 4 hotels were selected for our Q&A research, Our investigation was conducted largely frequency analysis, reliability analysis, factor analysis, and multiple regression analysis. First, as one of our study results, factors causing effects in service quality can be categorized into human service factors, physical service factors, and menu service factors. Second, the service quality of Korean restaurants has been found to exert effects on customer satisfaction, revisiting intentions, and word-of-mouth communication. Third, customer satisfaction has been determined to exert significant effects on revisiting intentions and word of mouth communication. Fourth, customer revisiting intentions has been found have been shown to exert significant effects on word-of-mouth communication. As one of the limits of this study, some difficulties did occur when attempting to implement Q&A research on customers who enjoyed restaurant services, as there was not sufficient space to interview them. As another limit, this study was conducted only with test subjects who had visited Korean restaurants in Five Star Hotels the results of our study cannot, then, be considered represent active of all Korean restaurants. Consistent with this future studies will need to be conducted not only with Korean restaurants, but also with Japanese, Chinese, and Western restaurants.

  • The purpose of this study was to look into how alliance discount cards affect customers using family restaurants by analyzing and identifying the difference in brand equity and satisfaction according to the propensity of using alliance discount cards. For this purpose, 407 customers who have used family restaurants completed a questionnaire survey. The study findings indicated that (1) there were significant differences in brand equity and satisfaction according to the propensity to use alliance discount cards. Moreover, it was found that groups with a strong propensity to use alliance discount cards had higher brand equity and satisfaction than groups that did not; also, (2) it was found that there were significant differences in brand equity and satisfaction according to the intensity of dependency on alliance discount cards. The group with strong loyalty to alliance discount cards went beyond the level of strong propensity to use alliance discount cards, of preference, and of use, which were previously proposed. This study implied that from mid-to long-term perspectives, it was necessary to operate a policy for more active alliance discounts as well as to ensure sufficient options for partnership benefits. Furthermore, it was essential to maintain the menu and service quality of restaurants, which were intrinsic factors for elevating brand equity and satisfaction in restaurants among dining customers.

  • This study is conducted to investigate to the consumption pattern of Kimchi and perception about the functional Kimchi of consumer. The survey was done between October 1 to October 15, 2011 among 294 male and female adults aged 19 and over in Seoul and Gyeonggi-do areas. The gender distribution of subjects was 33.3% males and 66.7% females. 64.3% of subjects prepared Kimchi by themselves, 23.5% of subjects received Kimchi from relatives and 12.2% of subjects purchased Kimchi from the market. In addition, the rate of preparing Kimchi at home is highest in those aged fifty or over. Only 41.8% of subjects knew how to make Kimchi. 72.1% of subjects responded that they ate Kimchi one or more a day. 46.6% of subjects have purchased commercial Chinese cabbage Kimchi. The amount of one-time purchase of commercial Kimchi were investigated; 45.2% of subjects have been buying 500-1 kg, 34.4% of the subjects bought less than 500 g, and 11.2% of subjects bought 1-3 kg. 28.2% of subjects buy Kimchi at the supermarket and warehouse market. With regard to the evaluation of Kimchi taste, most consumers were not satisfied with the sweetness of Kimchi. In this result, the perception about functional Kimchi was very low. Consumer's demands were as follows: nutrient enhancement, strengthening of biologically active substances, lactic acid bacteria enhancement in order. Small sales units were preferred by the consumers, and complementation of sweetness of kimchi was required. Various Kimchi including functional Kimchi must be developed to meet the needs of consumers.

  • This study was conducted to evaluate the neuroprotective effects of Cheonggukjang extract in in-vitro and in-vivo models. T98G-human glioblastoma cells were pretreated with various concentrations (1~10 mg/mL) of Cheonggukjang extract for 24 h and then exposed to $H_2O_2$ (1 mM) for 3 h. The neuroprotective effects of Cheonggukjang extract were measured using a CCK-8 kit assay, total antioxidant capacity (TAC) assay, reactive oxygen species (ROS) assay, and lactate dehydrogenase (LDH) release assay. The early stage focal ischemia rodent model was used as the in-vivo neurotoxicity model. Various concentrations (10~200 mg) of Cheonggukjang extract were administered to the animal models for 1 week. Peripheral blood was analyzed for glutathione peroxidase (GPx) expression by ELISA, and infarct volume reduction was analyzed by TTC staining. Cheonggukjang extract significantly (p<0.05) increased cell viability in T98G cells against $H_2O_2$ as well as against the induced neurotoxicity. Indeed, treatment with the Cheonggukjang extract induced a decrease in ROS and LDH expression and increased TAC significantly (p<0.05). However, Cheonggukjang extract did not induce a decrease in infarct volume or an increase in GPx expression in the in-vivo model. Despite the limitation in neuroprotection, Cheonggukjang extract may be useful for treating ROS injury.
