The main purpose of this study is to investigate the factors affecting customer satisfactions toward the italic restaurants of hotels. Especially, the role of menu-related factors is elaborated. Based on the previous research findings, the following hypotheses were proposed and tested. First, customer evaluations of the factors related to the service of italic hotel restaurants wi11 show differences, depending upon demographics. The results found are as follows. Concerning the seasonality and variety of menu, customer evaluations differed by gender. Depending on age groups, customer evaluations differed for the communicative quality of menu, the restaurant atmosphere, the employee service level, and the food taste. By the type of occupations, there were differences in customer evaluations of the communicative quality of menu, the employee service level, and tie food taste. By the education levels, there were differences in the evaluations toward the seasonality and variety of menu, the restaurant atmosphere, the employee service level, and the food taste, Finally. concerning the restaurant atmosphere and the food taste, customer evaluations differed by their income levels. Second, the employee service level, the seasonality and variety of menu, the communicative quality of menu, the restaurant atmosphere, and the food taste are predicted to significantly affect customer satisfactions, My results were consistent with this prediction except for that the communicative quality of menu did not significantly affect customer satisfactions. Regarding the role of menu-related factors in customer satisfactions, my finding implies the importance of updating the menu, providing the variety and reflecting the seasonality. The more studies, however, should be needed to explore the various roles of menu-related factors in restaurant customer satisfactions.

국내산 머스크멜론의 품종(Thankyou, Beauty, Picnic과 Sympony) 차이에 따른 $7^{\circ}C$ 저장 중 품질 변화를 조사하였다. Thankyou, Beauty, Sympony 품종은 28일, Picnic 품종은 21일까지 저장 실험이 가능하였다. 저장 초기 무기질 함량이 308.6 mg%이었던 Thankyou 품종의 경우에는 저장중 함량이 약 2.36%만 감소하였던 반면, Sympony와 Picnic 품종은 각각 28.53, 26.35%의 큰 감소를 보였다. 또한 초기 유리당 함량이 높았던 품종은 Thankyou와 Picnic 품종으로 13.3%이었으며, 다음으로 Sympony(9.8%), Beauty(8.0%)순이었으며, Thankyou 품종은 저장 28일후에도 12.8%의 가장 높은 유리당 함량을 유지하였다. Vitamin C 함량은 Sympony 품종이 26.0 mg/100 g으로 가장 높았으며, Picnic (21.36 mg), Beauty(20.53 mg), Thankyou(16.89 mg) 품종 순이었지만, 저장 14일 이후에는 11.5~12.5 mg%으로 품종간의 차이를 보이지 않았다. 호흡률은 저장 중 변화가 가장 크게 나타났던 Picnic 품종이 다른 품종들에 비하여 저장성이 떨어졌다. 관능검사에서도 Thankyou 품종의 기호도가 가장 뛰어났지만 꼭지의 수분손실은 저장 중 다른 품종들에 비하여 큰 것으로 나타남에 따라, Thankyou 품종의 머스크멜론 유통 시 꼭지 수분손실을 최소화할 수 있는 추가 연구가 필요하다.

This study was intended to investigate the relation between nutrient status and food diversity of elementary school students in Daegu-Kyungpook area. The subjects were 164 elementary school students (82 boys, 82 girls) who participated in "Dietary Intake Survey of Infants, Children and Adolescents" conducted by Korea Food & Drug Administration and Korea Health Industry Development Institute. We analyzed the nutritional status for two non-consecutive days by 24 hour recall method. Adequacy of dietary intake was evaluated by the proportion of subjects consuming nutrients less than Estimated Average Requirements (EAR). Food diversity was compared by using Dietary Diversity Score (DDS) and Dietary Variety Score (DVS). Nutrients intake was significantly higher in boys than girls. Subjects who consumed all food groups showed higher intake of energy and other nutrients. Boys maintained better diet quality than girls, measured by Dietary Diversity Score (DDS) as well as Dietary Variety Score (DVS). Based on these results, nutrition education for elementary school students should focus on the importance of consuming all food groups with more attention for girls.

This study was conducted to examine the correlation among meals variety, obesity index, blood pressure, and lipid profiles of Korean adults. A total of 308 adults(men 124, women 184) measured the anthropometric characteristics, blood pressure, dietary intake using 24-hour recall method, and serum lipid profile. The average ages of the study subjects were 50.9 yrs in men and 51.4 yrs in women. The average height, weight and BMI were 166.3 cm, 68.4 kg, $24.7\;kg/cm^2$ in men and 154.3 cm, 59.8 kg, $25.0\;kg/cm^2$ in women, respectively. The numbers of food items in meal of men and women were 14.1, 15.9 for breakfast, 15.7, 15.9 for lunch, 14.7, 14.1 for dinner, respectively. The numbers of dish items in meal of men and women were 4.0, 4.3 for breakfast, 4.3, 4.3 for lunch, 4.2, 3.9 for dinner, respectively. The average blood pressure, total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol and atherogenic index were 126.6/76.0 mmHg, 181.0 mg/dL, 157.7 mg/dL, 40.9 mg/dL, 108.6 mg/dL, 3.5 in men and 123.2/73.6 mmHg, 185.0 mg/dL, 137.3 mg/dL, 44.8 mg/dL, 112.7 mg/dL, 3.2 in women, respectively. The total cholesterol was negatively correlated to the number of food item for lunch(p<0.05). Therefore, more systematic studies to investigate the meal variety roles of blood lipids in meals of adults were required.

The purpose of this study was to evaluate the relationship between the diversity of food intake and nutrient intake among Korean college students participating in a nutrition education class via the internet. The subjects were 796 college students throughout South Korea (278 males, 518 females). A 3 days dietary recall survey was conducted and results were analyzed using the Computer-aided Nutritional Analysis Program. Dietary variety was assessed by DDS (dietary diversity score), MBS (meal balance score), and DVS (dietary variety score). Dietary quality was assessed by NAR (nutrient adequacy ratio), and MAR (mean adequacy ratio). As the DDS, MBS and DVS increased, the NAR and MAR improved. The subjects with a DDS of above 4 or a MBS of above 10 or a DVS of above 11 met two-thirds of the Korean recommended dietary allowance for most nutrients. The DDS, MBS and DVS correlated positively and significantly with the NAR and MAR. Associations between the NAR and high levels of DVS were more positive than those between the NAR and the DDS. Based on these results, the food intake of these subjects was not adequate. Specially, the dietary intake of calcium and iron were not adequate. Therefore, dietary guidelines should be made considering nutritional characteristics so as to improve the intake from all of the major food groups and provide a variety of foods in their diets.

The consumption of a wide variety of food groups is considered one of the key components of nutritional adequacy. The 2005 Dietary Guidelines for Koreans includes the consumption of a variety of foods from diverse food groups as a component of a normal diet. A survey was conducted to evaluate the relationship between the dietary diversity of food groups and nutrient intake in elderly patients (age 65 and above) at a rural area in Korea (Inje). 296 subjects (111 male and 185 female) were probed in a 3 day 24-recall dietary survey. Subjects were grouped according to food group intake frequency, based on six food groups (grain, meat/fish/legume/egg, vegetable, fat/oil, dairy, fruit). Nutritional quality was evaluated according to the numbers of nutrients under EAR (Estimated Average Requirements), and MAR (mean adequacy ratios). The frequency of elderly subjects consuming a meat/fish/legumes/egg food group less than once per day was 29.4%. The frequency of elderly subjects consuming fat/oil food group less than once per day was 65.8%. The percentage of subjects who did not eat dairy food was 88.8%, and that of subjects who did not eat fruit was 57.5%. A stepwise multiple regression analysis was used to develop models relating nutritional quality to possible food group intake frequency factors. Using the number of nutrients under EAR as a dependent variable, the meat/fish/legume/egg food group intake frequency explained 9.9% of variance, followed by the grain group, fat/oil group, dairy group, and vegetable and fruit group (Model $R^2$=0.260). For mean nutrient adequacy ratio as a dependent variable, the model $R^2$ was 0.326. The results of this study suggest that a highly varied diet in elderly might be associated with better nutritional quality, as assessed by nutrient intake. Accordingly, dietary guidelines should take into consideration nutritional characteristics in order to improve intake from all major food groups and to provide a variety of foods in the diet.
