Previous studies have shown that sodium excretion is positively related to calcium excretion in the urine. As excessive sodium intake is a common nutritional problem in Korea, we intended to investigate associations among sodium intake levels and calcium status, evaluated by 24 hour recall method and urinary excretion, and bone status. We collected dietary information for non-consecutive three days from 139 young adult women 19~29 years. After classifying the subjects into 4 groups based on the dietary sodium levels by daily total sodium intake (mg) and sodium density (sodium intake per 1000 kcal energy intake), we compared the bone status, nutrient intakes, urinary calcium and sodium excretions. The results showed a positive association between total daily sodium intake and intake of other nutrients. However, no significant differences in nutrients intakes were observed among subject groups classified by sodium density levels. There were no significant differences of bone density among groups by total daily sodium intake as well as by sodium density. While total daily sodium intake showed significantly positive relationship with urinary sodium (p < 0.05) and calcium (p < 0.05), sodium density was not related to urinary excretion of calcium and sodium. Our results suggested that promoting balanced meals providing appropriate amounts of energy intake is the essential component of nutrition education for improving calcium status of young Korean women with excessive sodium intake.

This study analyzed the dietary status of Southeast Asian workers living in South Korea in order to provide basic data to develop a program that allows workers to map desirable eating habits while living in Korea. Questionnaires were completed by 251 Southeast East Asian workers living in South Korea. From our study, we found that respondents ate three meals a day, and Vietnamese had less regular meal times than others. Thai, Cambodian, and Myanmar workers ate snacks several times a day, as they did in their own countries. For adapting Korean food, Vietnamese and Cambodian workers had difficulties due to spicy and salty flavors while Thai and Myanmar works had difficulties due to unfamiliar ingredients and cooking method. Thai workers were the fastest to adapt to Korean food, and the Thai ratio of eating homeland food daily was highest. Male respondents ate more often than women. Workers had access to cooking facilities in their house and usually ate more homeland food than workers that did not have access to cooking facilities. By providing understanding of dietary patterns of Southeast Asian workers, these results can be used as basic data to develop a program for Korean food adaptation.

This study was undertaken to test to fit forms of the Engel curves to data. The comparisons were confined to the linear, semi-logarithmic and double-logarithmic forms. Data from the 1970-1987 Urban Household Economy Survey were used to estimate the Engel curves. The twelve categories of consumption expenditure were considered for investigation. Parameters of the Engel curves were derived from OLS and TSLS. In this paper the size of the family was used as the deflater. The results could be summarized as follows: 1. Comparing with the R2 of three foms, it could be concluded that, the linear form generally gave a better fit to data than the other forms did. Only for housing and clothing and foot wear, did the semi-logarithmic form give a better fit. Only for meals outside the home, fuel, light and water charges, and miscellaneous, did the double-logarithmic form give a better fit. 2. Comping with the income elasticities based on the alternative forms, it could be concluded that the differences between the estimates were since each form made different assumption as to the way in which elasticity varied. In general, the semi-logarithmic form gave the highest estimate and double-logarithmic form did the lowest estimate. The difference between semi-logarithmic and the other forms were greater than the those of linear and double-logarithmic form. 3. It was found that the income elasticity varied with the difinition of income used as an explanatory variable in Engel curves.

This study was conducted to examine the needs of nutrition education based on analysis of the eating habits and nutrition knowledge among middle school students. The survey was conducted on 536 students (boys=216, girls=320) using a questionnaire. The average number of meals consumed was three (67.5%) and 58.0% of students reported having breakfast. Concerning the nutritional knowledge, students showed the highest score (girls, 0.90${\pm}$0.03 and boys 0.82${\pm}$0.04) for items describing the proper diet plan for obesity. Additionally, nutritional knowledge was found to have a significant effect on dietary habits. Regarding the necessity for nutrition education, high response rates for "For normal growth of students (44.8%)" and "Help to select proper food and choose safe food (24.0%)" were observed. Taken together, these findings indicate that consistent and systematic management is required under the institutional support by the school to improve students' perception regarding nutrition and to develop effective nutrition education.

The purposes of this study were to identify the attributes of food and service quality, to examine the levels of satisfaction and plate wastes leftover in school meals and to determine the relationship between student satisfaction and plate wastes. A questionnaire was administrated to 1000 elementary students. The respondents comprised of 505 boys and 494 girls. The satisfaction score with the food service quality was rated as 'average', with a score of 3.06 out of 5. The quality attributes of the food service were categorized into three aspects, which included food, service and hygiene. The satisfaction scores for the food- and hygiene-related factors were 3.20 and 3.24, respectively. However, the aspect of service was rated at 2.74, indicating a low level of satisfaction. The intake rates of soup, kimchi, fish and vegetables were lower than those of other types of foods. Two groups, a no-leftovers group and a leftovers group, were classified based on whether students ate all or left foods. The satisfaction scores for the school food service attributes between the two groups revealed that the no-leftovers group was more highly satisfied with the food service quality than the leftovers group (p＜0.001).

Studies on time-use have generally concentrated on the amount of time used by each member of a household in Korea. The quality of family relationships could be associated with the amount and types of interactions between family members. This study examined the time that adults spend with their family members on various activities. The purpose of this study is to explore a typology of family time and investigate the characteristics of each type. The data source was the 2009 Time-Use Survey conducted by the Korean National Statistics Office. The people involved in each activity were surveyed for the first time in the 2009 survey in Korea. The data from this study included 10,902 diaries that were filled on weekdays by married adults from ages 20 to 59 years. Data from rural households were excluded. Time use was divided into three categories: family meals, household work and family leisure time. These activities were analyzed using t-test, chi-square analysis and cluster analysis. Family time was classified into four types based on three categories. The four types were named "leisure sharing", "household work sharing", "overall sharing" and "non-sharing". The most common type was non-sharing. The characteristics of each type depended on gender and paid work time. Based on these results, family and labor policies should be developed to increase the work-life balance. Policies that focus on men over 40 years are especially recommended.

The Purposes of this study were to assess high school students' nutrient consumption at the ordinary time and to analyze nutrient contents and nutrition consumption of lunch. The questionnaires for self-reported food consumption were distributed to 210 students enrolled in a boy's high school and a girl's high school located in Seoul area. A final response rate was 87.1%, excluding responses that had significant missing data. Data of self-reported food consumption and BMI(Body Mass Index) were analyzed with descriptive analysis and t-test using SPSS Win(ver. 12.0). To measure the serving size and the waste amount, data were collected for three meals in a three day period at each school. A weighed plate method was employed to measure plate wastes and consumption of the menus served. Nutrient analyses for the served and consumed menus were performed using CAN-PRO. The result of nutrient intake determined by self-reported food consumption demonstrated 74.2% of boys and 70.0% of the girls did not meet EAR(Estimated Average Requirement) for calcium. In addition, the data collection showed that 60.2% boys and 26.7% girls did not consume EAR for Vitamin B$_1$. Nutrient analyses of the served and consumed menus at school lunch were compared with 1/3 of the Dietary Reference Intakes(DRIs) for this age group. The served menus did not meet 1/3 of the Recommended Intake(RI) for calcium, iron, and vitamin B$_2$. In contrast, the menu provided to students exceeded almost five times(490%) more than the sodium needed for 1/3 of the Adequate Intake(AI). Considering the amount of the students' plate waste, intake of vitamin A and vitamin C were below 1/3 of the RI, and calcium, iron, and vitamin B$_2$ intake were also reduced. Students' sodium consumption still exceeded 1/3 of the AI at 340.0%.
