Purpose: The purpose of this study was to assess the diet intake status and quality of adults from North Korea who had lived in Seoul and Gyeonggi-do, using the nutrition quotient (NQ) for Korean adults. Methods: A number of 166 adults aged from 20 to 64 years were enrolled as study subjects. A structured questionnaire was used to collect information on their demographic characteristics, food consumption frequency, eating behaviors, and NQ. The NQ score was then used to measure the overall diet quality. The NQ score was composed of four major age-based categories. 'Balance', 'Diversity', 'Moderation', and 'Dietary behavior' were utilized as scores for measurements within each of the four categories. The scores for all four categories were summed up, resulting in the total NQ score. Participants' age groups were stratified by 20's, 30's, 40', and over 50's. A χ² test and generalized linear regression (GLM) model were used to assess a significance for difference of subject distribution in categorical and continuous variables in the food consumption frequency, eating behaviors, and NQ scores. Results: Participants in younger age groups were more likely to report consumption of ramyeon, fast food, sweet and greasy baked products, processed beverage, delivery food, and night snacks than the older age groups. Most importantly, participants in 20's age group were less likely to report the total NQ and moderation score than the 50's age group. Conclusion: In this study, the 20's age group displayed a lower NQ characteristic for an unbalanced diet. Therefore, it is imperative for adults from North Korea to be given individualized diet instructions along with nutritional education programs.

A population-based study of people aged above 20 years showed that 32% had emmetropia and 68% had ammetropia(myopia 56.6%. hyperopia 11.4%) city in Korea. The percentage of ammetropia in population based study is higher than that of clinic(O.P.D.) based. A 83.3% of the ammetropia had myopia. which is higher than 76.3% of 1968 and 76.9% of 1975 years. A 16.7% of the ammetropia had hyperopia. which is lower than 19.4% of 1968 and 17.3% of 1975 years. In the kind of refractive error. 32.1% of 985 eyes examined had compound myopic astigmatism. 18.2% had simple myopic astigmatism. 14.2% had simple myopia. 6.8% had simple hyperopic astigmatism, 5.0% had mixed astigmatism, 4.7% had compound hyperopic astigmatism and 3.6% had simple hyperopia. In the difference of binocular refractive error, 29% had 0.50~2.00 Dptr difference and 3.6% had difference above 2.00 Dptr. In age related myopic refractive error, 76.7% of people aged 20~29 years and 74.0% of 30~39 years had myopia. It is due to overstudy for entrance into a university that the percentage of myopia is higher than that of abroad. In age related hyperopic refractive error, 2.9% of people aged 20~29 years, 0.6% of 30~39 years. 6.3% of 40~49 years, 16.0% of 50~59 years and 63.9% of 60~69 years had hyperopia. It shows that the age related hyperopic refractive error was significantly increased at aged 40~49 years. The right eye had more myopic refractive error than left eye.

The purpose of the current study was to identify expectations regarding aging and health-promoting behaviors and to examine whether expectation regarding aging was associated with health-promoting behaviors among community-residing Korean adults. Data were collected from 233 adults dwelling in the community of Daegu and Kyungpook province. The influence of expectations regarding on health-promoting behaviors was analyzed through hierarchical multiple regression controlling for sociodemographic variables. As a result, the mean score of expectations regarding aging was significantly lower in 40s and 50s than 20s and 30s. The participants had the lowest expectations regarding aging in terms of physical health domain and the highest expectations in terms of mental health domain. No significant differences were found in health-promoting behaviors among different age groups. After controlling for sociodemographic variables, expectations regarding aging were independently associated with health-promoting behaviors in adults in 20s~30s but not in those in 40s~50s. The findings suggest the need for encouraging Korean adults to strive for having positive and active perspective on aging and for getting higher expectations regarding aging, in particular, for 20s and 30s, as a health-promoting strategy.

This study was performed to develop yut(Korean Traditional Candy), products using dried-persimmon, with the ratio of 5, 10, 15, 20 and $25\%$, and the quality characteristics were investigated. The proximate compositions of dried-persimmon were $29.67\%$ moisture, $1.76\%$ crude protein, $0.18\%$ crude lipids, $1.31\%$ crude ash and $3.92\%$ crude fiber, respectively. Brix of yut products were ranged from $81.5\%$ to $83.0\%$. With increasing the amount of dried-persimmon, hunter's color values of Land b were reduced. In the texture property, the addition of dried-persimmon increased hardness, fracturability, gumminess and chewiness, while decreased adhesiveness. Judging from texture, taste and overall acceptability of the yut product, the recommended substitution level of dried-persimmons was $10\%$. In consumer sensory score, the $twenties\~sixties$ gave high score of color, while the $thirties\~fifties$ gave high score of sweetness. Overall acceptance of yut products of $dried-persimmon$ were good in old-age consumers.

There is likely to be a fit problem when women aged in their 30s-40s purchase down-age clothing from brands that target women in their 20s. To identify the part of the lower body that causes the fit problem, the sizes and types of lower body of women in their 30s-40s were compared with those of women in their 20s. The data for this study was from the 2010 Size Korea survey of body measurements of 1675 female adults in their 20s-40s. To examine differences in the average sizes of the lower body between women in their 20s and 30s-40s, descriptive statistics and t-tests were conducted. Factor and cluster analysis were used to classify body types by age groups. On the whole, compared to women in their 30s-40s, women in their 20s were found to be higher for all height items and smaller for size, thickness and width items. The result of the Glycemic index analysis showed that the body type of women in their 20s was generally larger than that of women in their 30s-40s. In addition, women in their 20s had a large drop value compared to those in their 30s-40s, whereas flatness of body cross section was bigger in the group of women in their 30s-40s. Four factors related to the lower body type of female adults in their 20s-40s were identified in the factor analysis, and three categories of body type were identified by cluster analysis. A Type 1 individual had abdominal obesity and chubby lower limbs, Type 2 had short legs and slightly chubby lower limbs, and Type 3 had long legs and a skinny lower body. A significant number of women in their 30s-40s were included in the Type 1 group, which was the least common category for women in their 20s.

This study investigated the post-divorce adjustment level, by focusing on life satisfaction, health, stress and resource factors, for divorced men and women in their 20s and 30s. Also, it examined how these factors affect life satisfaction and health. For this empirical analysis, data were collected from 114 divorced men and 112 divorced women, living in the Seoul metropolitan area, from 23rd Sep. to 20th Oct., 2002. The questionnaire for the survey dealt with demographic information, life satisfaction, health, stress and resource factor scales. The major findings of the research project were as follows.: first, the life satisfaction and health levels of the divorced men and women were low. Especially, divorced women had more physical and psychological problems than men. Second, the divorced men's satisfaction was affected by pre-divorce life events and education level, whereas the divorced women's satisfaction was affected by subjective economic dissatisfaction, pre-divorce tfe events, everyday life level when they were divorced, and social support. Finally, the attitude toward divorce of significant others and pre-divorce life events were important variables for the divorced men's health, whereas attachment toward ex-spouse, pre-divorce life events, pre-divorce marital conflict and social support were affectable variables for the divorced women's health. The results of current research are expected to contribute to the divorce adjustment programs according to gender.
