This study is conducted to explore the cooks' recognition of culinary environment of school feeding among the cooks working for elementary schools, middle schools, and high schools in the Ulsan district. A total of 200 samples were distributed and 185 samples were collected; among them, 182 valid samples were selected for research. Answers were processed by SPSS 12.0. after data coding. As for factor analysis of culinary environment, three factors were extracted, which are general environment, human environment, and facilities equipment environment. It was found that general environment included ventilation(31.5%), temperature (29.0%), humidity(22.1%) in the order of importance; human environment covered cooperation among cooks (28.1%), the number of cooks(25.7%), and professionalism of cooks in the order of importance; facility equipment environment contained the design and layout of facilities and equipment(29.3%), various safety facilities, and safety device(23.3%) in the order of importance. However, a measure for improving work environment, number of cooks, deterioration of equipment, etc. should be considered.

The purpose of this study was to measure the causal relationships among affective belief, ambivalence, subjective norm, attitude, intention to consume and meat consumption. A total of 318 questionnaires were completed. The structural equation model was used to measure the causal effects among constructs. The results demonstrated that the confirmatory factor analysis model provided excellent model fit. The proposed model yielded a significantly better fit to the data than the baseline model. The effects of affective belief, ambivalence and subjective norm on attitude were statistically significant. The effect of subjective norm on intention was statistically significant. As expected, subjective norm and attitude had significant effects on meat consumption. Moreover, affective belief, ambivalence and subjective norm had indirect influences on meat consumption. Subjective norm also had an indirect influence on intention. The overall findings offered strong empirical support for the intuitive notion that improving the level of attitude toward eating meat can increase favorable intentions and decrease unfavorable intentions to reduce future meat consumption.

The purpose of this study was to measure the estimated coefficient and marginal willingness to pay of attribute level: origin logo, origin description, traditional food, fusion food, service guarantee, and price, which influence tourist preference for restaurants. Also, the study identified the attribute which confers the highest importance to tourists. Conjoint experiment and the ordinal probit model were used for this study. A total of 210 surveys were conducted by tourists. The findings from this study were as follows. First, the effects of all attributes on tourist preference for restaurants were statistically significant. Second, tourists regarded an origin logo as the very important attribute, and were more willing to pay for the case where the menu contained origin logo. These findings suggested new marketing opportunities for restaurant managers. Although this study provides some evidence on the value of the local product brand to tourists, a similar measure has not been developed for local residents. This is an area in need of future research.

The effects of vitamin E supplement on 15%(w/w diet) perilla or corn oils were studied in rat hepatocellular chemical carcinogenesis induced by modified Solt & Farber model, which consists of 20mg/kg body weight diethylintrosamine(DEN) injection, 3 weeks feeding of 0.02%2-acetylaminofluorene(2-AAF) and partial hepatectomy. The area of placental glutathione S-transferase(GST-P) positive foci tended to be smaller in perilla oil group had lower thiobarbituric acid reactive substances(TBARS) CONTENT. Fatty acid compositions in microsomal membrane were reflected by dietary fatty acid compositions, and not affected by carcinogen treatment or vitamin E supplement. By vitamin E supplement, linolenic acid contents of perilla oil group were much increased. By carcinogen treatment, membrane stability decreased significantly in corn oil, but maintained in perilla oil groups Vitamin E supplemental effect was noticed only in the corn-carcinogen group. Perilla oil may prevent hepatocarcinogenesis by maintaining membrane stability and by reducing cytochrome P-450 content. Vitamin E supplement did not seem to have the effect on hepatocarcinogenesis, but prevented lipid peroxidation, reduced cytochrome P-450 content and maintained membrane stability.

This study examines the changes in the physicochemical property and antioxidant activity of six types of vegetables (carrots, crown daisy, mugwort, cabbages, onions, and garlic) based on heat-treated cooking. According to the results, proximate contents (crude protein, fat, and ash) were lower in blanched samples than in untreated samples. Untreated cabbages showed the highest level of total dietary fiber content, which decreased by blanching and increased by high-temperature/high-pressure (HTHP) treatment. Noteworthy is that, in the case of soluble dietary fiber, blanched crown daisy and mugwort showed significantly high levels of 12.0 g and 7.3 g per 100 g(dry basis). There was no significant change in tocopherol content in heat-treated samples. The highest levels of total polyphenol and flavonoid content were 6.73 g and 5.51 g per 100 g, respectively, in the mugwort sample with HTHP treatment at $130^{\circ}C$ for 2 h. The water extract of mugwort with HTHP treatment had the strongest antioxidant effect based on three bioassays (SOD, DPPH, and ABTS). These results indicate the relative correlation between the level of physiologically active content and antioxidant activity and suggest new insights into ingredients for developing functional foods.

For development of food of Jong-ga (Jeonju Hakindang) and its commercialization, this study investigated physico-chemical properties and quality characteristics of Mannaji (boiled beef down in Korean soy sauce) prepared with conventional or pre-heating methods during storage period (0, 4, 8, 12, 16, and 20 weeks) at $4^{\circ}C$. As storage period passed, pH decreased in both conventional and pre-heating methods. Forchromaticity, brightness ($L^*$) significantly decreasedwhile redness ($a^*$) and yellowness ($b^*$) significantly increased during storage period. After 4 weeks of storage, hardness of Mannaji with conventional methods was higher compared to before storage. Thiobarbituric acid reactive substances (TBARS) of both conventional and pre-heating methods increased above 1.2 MDA mg/km, which is the acceptable criteria for intake. Although volatile basic nitrogen (VBN) values slightly increased in 4 weeks of storage, there were no significant differences in VBN and maintained food acceptable level until 20 weeks of storage. Sensory panelists showed preference for Mannaji with pre-heating methods compared to conventional methods.

The carcass size performances and the meat quality of Gannan and Sibu yak were determined using M. supraspinatus (SU), M. longissimus thoracis (LT) and M.quadriceps femoris (QF). It is found that Sibu yak had significantly higher carcass weight (CW) than Gannan yak with difference of nearly 40 kg, as well as significantly higher eye muscle area (EMA), carcass thorax depth (CTD), round perimeter (RP), etc. The carcass performances of steer yak were significantly higher than heifer yak except meat thickness at round (MTR) (p<0.05). The results show that both yak breed and gender had significant effects on carcass performances. It could be seen that the variation of carcass size performances from breeds is as large as from gender (50.22% and 46.25% of total variation, respectively) through principal component analysis (PCA). Sibu yak had significantly higher L*, b*, WBSF, cooking loss and Fat content, while Gannan yak had significantly higher a*, press loss, protein content and moisture (p<0.05). Yak gender and muscle had insignificant effects on meat colour and water holding capacity (p>0.05). The variation of meat quality of yak from breed is up to 59.46% of total variation according to PCA. It is shown that the difference between breeds, for Gannan yak and Sibu yak, plays an important role in carcass size performance and meat quality.

This study tried to develop Siraegi by boiling it down in soy seasoning sauce with excellent sensory attributes and evaluate the quality characteristics in order to enhance the value of traditional agricultural products, dried radish leaves. Sugar content of the seasoning sauce were finally established at 30% (w/v) compared with the starch syrup, which was added to the sauce through sensory evaluation among four groups, 0%, 30%, 60% and 100%. The texture (breaking strength) of Siraegi which was boiled for 30 minutes in water with baking powder was reduced by showing softening effect ranging from 7.6% to 42.1% as the amount of added baking powder was increased. The color of braised Siraegi produced with prepared a seasoning sauce and different content of baking powder, the brightness significantly decreased with an increase of baking powder. The reduction effects of breaking strength ranged from 25.6% to 43.9%, resulting a significant difference. The pH of braised Siraegi with a seasoning sauce significantly increased from 5.71 to 6.04 as the amount of added baking powder was increased, while its acidity was decreased. Sensory evaluation showed significant values for hardness and toughness as the values dropped when compared with the control (p<0.001), and overall acceptability of the group with adding 0.2% baking powder was best (p<0.001). In conclusion, baking powder could be considered as softening agent shorting the cooking time and improvement of the acceptability. Furthermore, it was expected that the newly developed soy sauce barised Siraegi using the dried radish leaves would be successfully utilized by side dishes in the food preparation industry.
