  • Korean foods sold restrant and hotel accompaines so many kinds of side dishes. The menues never considered on the nutritional standpoint nor the volume that can be eaten by customers. The purpose of this study is to simplify and improve the menu of Korean foods sold in restrant. To find out the problem and the method of the betterment Korean food sold in restrant. The survey study was made for 100 restrants in Seoul city. Ther average number of side dish of the restrant food was 23. The average amount number of the side dish was 31 and smallest number was 4. The average amount of food served was 979 grams and the average number of food taken by people was 698 grams. The average percentage of intake of food was 62%. Protein Content of the foods sold restrant was from 54% to 240% over the recommended dietary allowances. Protein intake also exceeded from 19% to 147% of recommended dietary allowances. Age of the customers were surveyed to set up the standard amount of the nutrients. About 68% of the customers were from 30 to 40 years of age in the day time (lunch), whereas about 72% were from 20 to 30 years of age in the evening (supper). From the results of the survey study, two nutritional standard were decided to be used. One is the recommended dietary allowences of 25 years of man (reference man), and the other is that of 45 years of man. The actual standards are as follows : Standard 1 (25 years of man) Calories-900~1000Cal Protein-25-30g Vegetables-200~250g (include yellow, green vegetable), Amount of food-about 800g Standard 2 (45 years of man) Calories-700~800Cal Protein-25~30g Vegetables-150~200g (include yellow, green vegetable) Amount of food-700g The kinds of food recommended to be sold in the restrant are as follows : 1. Pansang-is a formal method of korean table setting 3 types, 7 chup, 5 chup, and 3 chup were studied and made, 2.

  • In order to improve the quality of sikhe, Korean traditional sweat rice drink, wheat malt, covered barley malt and naked barley malt were used to prepare sikhe. The optimum temperature of amylase was $60^{\circ}C$ in malt extract. After heat treatment of amylase for 2 hr at $70^{\circ}C$, residual activity of amylase was less than 20% in malt extract. Amylase activity during sikhe preparation was decreased gradually. The sikhe saccharifyed for 6 hr had $6250{\sim}25029$ units of amylase acitivity. The contents of glucose, maltose and maltotriose were increased with increasing time. Maltose content was the highest, followed by glucose and maltotriose. The pH and titrable acidity were slightly changed. The sweetness of sikhe prepared with wheat was 11.3%, and others were 11.1% and 10.4%. The sikhe prepared with naked barley was evaluated the most palatable sikhe.

  • The purpose of this study was to examine the relationship between bone density and dietary intake for college women in their twenties. This study was performed on 160 female college students residing in Gangwon-do. It was conducted using ultrasound measurement of calcaneus bone density, anthropometric checkup and food-frequency questionnaires (FFQ) comprising 94 kinds of commonly consumed foods. Subjects were divided into two groups according to the T-score of bone density: a normal group (n = 113 persons, T-score ${\geq}1$) and a risk group (n = 47, T-score < 1.0). The average age of the subjects was 20.17 years and there was no significant difference between the two groups. Body weight and body fat percentage of the normal group were significantly higher than those of the risk group. The mean daily energy intake of the normal group was significantly higher than that of the risk group. Also, protein, fat, vitamin A, niacin, vitamin B6, folate, calcium, phosphorus, sodium, potassium, iron and zinc intake for the normal group were significantly higher than for the risk group. For the intake of the commonly consumed foods (or dishes) listed in FFQ, the mean daily intake amount of loaf bread, rice cake, potatoes, spicy beef soup, cucumber, seasoned spinach perilla leaves, crown daisy, stir-fried mushroom, sea mustard, beef rib, ham, chicken, mackerel, common squid, drink type curd yogurt, oriental melon and chocolate in the normal group was significantly higher than in the risk group. While, the mean daily intake of ramyun (instant noodle) and carbonated beverage by the normal group was significantly lower than that of the risk group. In conclusion, 20 something female college students showed a higher rate (26.9%) of the bone mineral density risk group (osteopenia or osteoporosis). For the risk group, the levels of nutrient and food intake were lower than in the normal group. Therefore, the bone density risk group needs to increase their nutrient intake and diet quality by increasing the intake of various foods. In addition, they should decrease the intake of foods, which are negative for skeletal health such as instant noodles and carbonated beverages.

  • Barley is a main food source, along with rice, in our dietary life that is easy to buy and process. It is required to develop a beverage base and barley syrup for desserts in order to raise utilization of barley beyond its present use in Sikhye (sweet fermented rice drink) and Jocheong (grain syrup) production. In pursuit of the goal to increase the usability of barley as an ingredient of processed food, this study examined the optimal preparation conditions of barley mash for barley syrup. In addition, the study prepared a barley syrup using saccharified barley liquid, analyzed quality characteristics, and conducted a sensory evaluation. Saccharified barley liquid(barley mash) was prepared with ratios of adding malt of unhulled barley germinated as 0 g(CON), 10 g(BM10), 20 g(BM20), and 30 g(BM30). The results of measuring pH under the varied conditions of saccharification temperatures from $50^{\circ}C$, $60^{\circ}C$, and $70^{\circ}C$, as well as time from 1 to 8 hours, treveal that the optimum condition for malt saccharification is $60^{\circ}C$ for 5 hours. By adding oligosaccharides and lemon juice to the saccharified barley liquid at the different ratios of added malt, this study measured quality characteristics(color value, viscosity, pH, sweetness) of barley syrup warmed up for 1 hour. As the result of measuring color in the barley syrup prepared by saccharified barley liquid, higher levels of added malt saw L-value decreased while a-value and b-value both increased. BMs30 showed the highest viscosity of $1,202.67{\pm}3.06$. As for pH, BMs30 was the highest at pH $3.57{\pm}0.02$. The result of the sensory evaluation of barley syrup showed the superior sensory characteristics of BMs20 in terms of color, flavor, sweetness, viscosity and overall quality.

  • This study described the status of snack intake and personality of middle school students, determined the differences in snack intake and personality according to gender and grade levels, and examined the effect of snack intake on personality. Data were collected from a self-reported survey from students of a middle school in Gwangju city and 717 questionnaires used for the analyses. The data were analyzed for frequency, percentage, mean, standard deviation, Cronbach's α, t-test, ANOVA, Duncan test, and multiple regression analysis using SPSS/PC 18.0 program. The results obtained were as follows. First, as for the snack intake frequency, '1~2 times per a day' had the largest number of responses(42.3%), followed by 'sometimes'(37.6%), '2~3 times per a day'(12.6%), 'never'(7.5%). As for the reason of snack intake, 'habitually'(27.3%) had the largest number of responses, followed by 'insufficient amount of meal'(21.0%), 'skipping meals'(13.6%), and 'stress relief'(8.2%). Mean score of agreeableness was the highest(3.64) among the personality components followed by Openness/intellect(3.42), Extraversion(3.36), Conscientiousness(3.15), and Emotional Stability(3.09) on the 5-point scale. Second, there were statistically significant differences in Emotional Stability depending on the gender. There were statistically significant differences in Extraversion, Agreeableness, and Openness/intellect by the grade level. Third, fruit intake frequency had statistically significant influence on Extraversion(β=.134). Intake frequency of bread(β=-.099), fruit(β=.142), ice cream(β=.092), and rice cake(β=.090) had statistically significant influence on Agreeableness. Intake frequency of bread(β=.105), drink(β=-.113), fruit(β=.113), and flour-based food(β=-.126) had statistically significant influence on Emotional Stability. Intake frequency of fruit(β=.106) and milk(β=.110) had statistically significant influence on Openness/intellect. Intake frequency of fruit had statistically positive influence on all the personality components. Intake frequency of rice cake had statistically positive influence on two personality components. Intake frequency of drinks had statistically negative influence on Emotional Stability. The outcomes indicate that snack intake affects the personality of adolescents.

  • This study has been carried out to measure the amount of the daily intake by Korean on preservatives (Dehydroacetic acid, Benzoic acid and ρ-Hydroxybenzoic acid asters) in foods. The amounts of preservatives were determined by HPLC in foods such as butter, cheese, margarine, aloe gel, carbonated beverages, mixed beverage, ginseng beverage, red ginseng drink, soy sauce, fruit and vegetable juices (except unheated fruit-vegetable juice), vineger, seasonings, fruit and vegetables only on the peel, fruit wine, rice wine and unrefined rice wine. The recovery ranges were found to be 99.2% for dehydroacetic Acid, 95.8% for benzoic acid and $94.2{\sim}97.2%$ for ${\rho}-hydroxybenzoic$ acid in foods, respectively. The data of average food intake for each food items per capita per day were obtained from the report of national nutrition survey carried by the Ministry of Health and Welfare in 1997. The detected number of samples and average intake range of preservatives have been figured cut to $ND{\sim}290.0{\;}ppm$ for dehydroacetic acid, $ND{\sim}400.0{\;}ppm$ for benzoic acid and $ND{\sim}93.9{\;}ppm$ for ${\rho}-hydroxybenzoic$ acid esters, respectively. Estimated daily intake (EDI) of each additives per capita per day were shown as follows; 1.56 mg for dehydroacetic acid, 2.25 mg for benzoic acid and 0.44 mg for ${\rho}-hydroxybenzoic$ acid esters in total respectively and these values were evaluated to be much lower than that of FAO/WHO's acceptable daily intake (ADI) $0{\sim}5{\;}mg/kg$ b.w./day for benzoic acid and $0{\sim}10{\;}mg/kg$ b.w./day for ${\rho}-hydroxybenzoic$ acid esters.

  • The purpose of this study was to categorize the gap between coffee shop 'importance' (as perceived by customers before patronizing the coffee shop) and 'satisfaction' (perception of customers after patronizing the coffee shop) as positive or negative and to analyze the effect of these gaps on purchasing behavior. To do this, I used the gap between importance and satisfaction regarding the choice of a coffee shop as the explanatory variable and performed an empirical analysis of the direction and size of the effect of the gap on purchasing behavior (overall satisfaction, willingness-to-revisit) by applying the Ordered Probit Model (OPM). A previous study that used IPA to evaluate the effects of gaps estimated the direction and size of a quadrant but failed to analyze the effect of gaps on customers. In this study, I evaluated the effects of positive and negative gaps on customer satisfaction and willingness-to-revisit. Using OPM, I quantified the effect of positive and negative gaps on overall customer satisfaction and willingness-to-revisit. Per-head expenditure, frequency of visits, and coffee-purchasing place had the most positive effects on overall customer satisfaction. Frequency of visits, followed by per-head expenditure and then coffee-purchasing place, had the most positive impact on willingness-to-visit. Thus per-head expenditure and frequency of visits had the greatest positive effects on overall satisfaction and willingness-to-revisit. This finding implies that the higher the actual satisfaction (gap) of customers who spend KRW5,000 or more once or more per week at coffee shops is, the higher their overall satisfaction and willingness-to-revisit are. Despite the fact that economical efficiency had a significant effect on overall satisfaction and willingness-to-revisit, college and university students still use coffee shops and are willing to spend KRW5,000 because they do not only purchase coffee as a product itself, but use the coffee shop for other activities, such as working, meeting friends, or relaxing. College and university students also access the Internet in coffee shops via personal laptops, watch movies, and study; thus, coffee shops should provide their customers with the appropriate facilities and services. The fact that a positive gap for coffee shop brand had a positive effect on willingness-to-revisit implies that the higher the level of customer satisfaction, the greater the willingness-to-revisit. A negative gap for this factor, on the other hand, implies that the lower the level of customer satisfaction, the lower the willingness-to-revisit. Thus, the brand factor has a comparatively greater effect on satisfaction than the other factors evaluated in this study. Given that the domestic coffee culture is becoming more upscale and college/university students are sensitive to this trend, students are attentive to brands. In most upscale coffee shops in Korea, the outer wall is built out of glass that can be opened, the interiors are exotic with an open kitchen. These upscale coffee shops function as landmarks and match the taste of college/university students. Coffee shops in Korea have become a cultural brand. To make customers feel that coffee shops are upscale, good quality establishments and measures to provide better services in terms of brand factor should be instituted. The intensified competition among coffee shop brands in Korea as a result of the booming industry indicates that provision of additional services is needed to differentiate competitors. These customers can also use a scanner free of charge. Another strategy that can be used to boost brands could be to provide and operate a seminar room for seminars and group study. If coffee shops adopt these types of strategies, college/university students would be more likely to consider the expenses they incur worthwhile and, subsequently, they would be more likely to be satisfied with the brands of these coffee shops, with an associated increase in their willingness-to-revisit. Gender and study year had the most negative effects on overall satisfaction and willingness-to-revisit. Female students were more likely to be satisfied and be willing to return than male students, and third and fourth-year students were more likely to be satisfied and willing-to-return than first or second-year students. Students who drink coffee, read books, and use laptops alone at coffee shops are easily noticeable. High-grade students tend to visit coffee shops alone in order to use their time efficiently for self-development and to find jobs. The economical efficiency factor had the greatest effect on overall satisfaction and willingness-to-revisit in terms of a positive gap. The higher the actual satisfaction (gap) of students with the price of the coffee, the greater their overall satisfaction and willingness-to-revisit. Economical efficiency with a negative gap had a negative effect on willingness-to-revisit, which implies that a less negative gap will result in a greater willingness-to-revisit. Amid worsening market conditions, coffee shops located around colleges/universities are using strategies, such as a point or membership card, strategic alliances with credit-card companies, development of a set menu or seasonal menu, and free coffee-shot services to increase their competitive edge. Product power also had a negative effect in terms of a negative gap, which indicates that a higher negative gap will result in a lower willingness-to-revisit. Because there are many more customers that enjoy coffee in this decade, as compared to previous decades, the new generation of customers, namely college/university students, want various menu items in addition to coffee, and coffee shops should, therefore, add side menu items, such as waffles, rice cakes, cakes, sandwiches, and salads. For example, Starbucks Korea is making efforts to enhance product power by selling rice cakes flavored in strawberry, wormwood, and pumpkin, and providing coffee or cream free of charge. In summary, coffee shops should focus on increasing their economical efficiency, brand, and product power to enhance the satisfaction of college/university students. Because shops adjacent to colleges or universities enjoy a locational advantage, providing differentiated services in terms of economical efficiency, brand, and product power, is likely to increase customer satisfaction and return visits. Coffee shop brands should, therefore, be innovative and embrace change to meet their customers' desires. Because this study only targeted college/university students in Seoul, comparative studies targeting diverse regions and age groups are required to generalize the findings and recommendations of this study.

  • This study was carried out to investigate the self-reported health and eating habit of the elite female adolescent athletes in Incheon. The subjects were 102 elite female athletes of middle and high schools located in Inchon. A self-administered Questionnaire was used for this cross-sectional survey. Statistical analysis by two-way ANOVA was performed to discriminate between the main effects of age (as middle and high school athletes) and sports type, and their interaction. As use of nutritional supplements, 35.8% of the total subjects took vitamin and iron supplements and 62.5% of field and track athletes took vitamin and iron supplements. While mental stress related to exercise was much in fencing &gt; shooting &gt; field and track &gt; swimming athletes, physical burden during training was higher in swimming &gt; field and track &gt; fencing &gt; shooting athletes. More than half of the subjects showed irregular menstrual cycle. As the most severe problem of eating habit, they reported skipping meal &gt; overeating &gt; prejudiced meal &gt; preference to salty and spicy foods. More than half of the subjects skipped meal over three times per week. Fencing and shooting athletes showed very significantly higher frequency of skipping meal and more irregular breakfast time compared to those of other sport types. As for snack, they ate cookies, carbonated drink, chocolate, candy &gt; milk, yogurt, ice cream &gt; cake, bread, rice cake &gt; fried noodle &gt; hamburger, pizza. Therefore, nutritional counseling and education by sport type are necessary for health and good eating habit of these elite female adolescent athletes.
