The purposes of this research are to explore factors that affect re-employment revitalization of the semi-aged workers and to seek practical and specific improvement plans to activate the semi-aged worker's re-employment. For the purposes of this research, face to face interviews were conducted between March 18th and April 10th, 2016 among 375 semi-aged who are currently searching for a job or re-employed among the semi-aged between 50 and 64 years old and reside in Daegu Metropolitan City. According to logistic regression analysis, sex, subjective health condition, working period, and information supply have statistically significant positive impacts on re-employment of the semi-aged workers. On the other hand, simple labor work and seeking job period have statistically significant negative impacts on re-employment of the semi-aged workers. Finally, policy implications for the improvement of re-employment of the semi-aged workers were introduced and discussed.

This study analyzed the characteristics and meaning of care labor by examining the experience of semi-aged caregivers. To that end, in-depth interviews were conducted for a qualitative study of 15 semi-aged caregivers working at elderly care facilities located in the Kyunggi-do region. The interview was conducted with a major focus on three categories: perception of care labor by semi-aged caregivers; stress experienced in the course of care labor; and insights earned through care labor. The analysis showed that semi-aged caregivers have a positive experience through care labor. This finding will contribute to understanding the characteristics and meaning of semi-aged care labor from a different perspective.

The aim of this study was to assess the nutrient intakes of the elderly subjects in Korea. Dietary assessment was carried out using a semi-quantitative food frequency questionnaire (SQFFQ) developed by our laboratory, which included 98 commonly consumed food items selected from 1998 National Health and Nutritional Survey for Korean population. Subjects (n = 2,660) aged 50yr and over were recruited in Seoul, 6 metropolitan cities, and 8 mid-size cities. Calcium and riboflavin intakes of the elderly subjects aged 65 yr and over (n = 1,974) were much lower compared with Korean RDA. Nutrient intakes of the three age group (50-64 yr, 65-74 yr, 75 yr and over) were decreased as age increased in male and female elderly. Nutrient intakes of male elderly, 75 yr and over, were significantly decreased while in female elderly nutrient intakes were gradually decreased as age increased. Over 30% of the elderly subjects did not meet 75% RDA for calcium, iron, vitamin A, and riboflavin. The proportion of the elderly subjects whose intakes were below 75% RDA was much higher than the elderly whose intakes were above 125% RDA, especially among the elderly aged 75 yr and over. This study revealed that the Korean elderly had inadequate intakes for many nutrients. This will cause a serious nutritional problem for the elderly.

This study investigated the casual jacket design preferences of women aged 50s and 60s and suggested a prototype design for functional clothing. All age groups liked the casual jacket with a length between the waist and hip, a convertible collar, and a single-breasted design. Those in their 50s preferred fitted or semi-fitted casual jackets while those in their 60s preferred semi-fitted casual jackets. Although, there were significant differences between the preferred jacket designs and ready-made brand jacket designs, most brand jacket designs were casual, semi-fitted, middle-hip length, single-breasted, and with stand-rolled or convertible collars. The analysis of the sleeve styles in brand jackets showed that consumers needed designs that are more decorative. Fashion designers for senior citizens need to design elderly clothing that is comfortable, fashionable, functional, and considers a universal design for ease of clothing function. It will also make the senior citizen fashion market more appealing to consumers. To provide jacket designs for senior citizens, we suggested casual jacket designs for embedding a functional device as well as a new jacket design library for women in their 50s and 60s.

The purpose of this study was to develop a semi-quantitative food frequency questionnaire (SQ-FFQ) for subjects aged 50yr and over and to evaluate the validity of this SQ-FFQ. Dietary intake was assessed using SQ-FFQ that included 98 commonly consumed flood items selected from the results of the Korean Health and Nutritional Survey, 1998. Subjects (n = 2,660) aged 50yr and over were recruited from 7 metropolitan cities and 8 small cities. Each subject was interviewed using this SQ-FFQ developed in our laboratory and 24hr-recall method. Excluding incomplete data, Data from 1,149 subjects were used in this validity study. The nutrient intakes assessed by this SQ-FFQ were validated by comparing with the results from 1 day 24-hour recalls. Pearson's correlation coefficients between two methods were 0.71, 0.64, 0.53, and 0.43 for energy, carbohydrate, protein, and fat, respectively for all subjects. Spearman's correlation coefficients were higher than those of Pearson's correlation coefficients. Kappa values for energy, carbohydrate, protein, and fat were 0.79, 0.72, 0.70, and 0.64, respectively. The percentage for misclassification of the lowest quartile into the highest quartile or vice versa was 1.25-1.39% for all nutrients. Therefore, this SQ-FFQ seems to be useful in assessing the nutritional status of the middle-aged and elderly subjects in Korea.

This study aims to look at the factors affecting later-life expectation of semi-older adults. Total of 323 participants aged from 50 to 64 was used for analysis from the data of 'Korean's Perception on Aging Society', which was conducted on behalf of Initiative for Humanities' Research and Education, funded by National Research Foundation of Korea. Multiple regression analysis was used for analysis, and the results are as follows. First, later-life expectation of semi-older adults appeared to be high. Second, the significant factors were prejudice towards the elderly and social solidarity. That is, participants with lower prejudice towards the elderly and higher trust and solidarity with society showed greater later-life expectation. Based on the results of this study, future research directions and implications for policy and practice were suggested.

The principal objective of this study was to develop a processed food using aged garlic. Pound cake samples were prepared with semi-solid aged garlic at levels of 0, 5, 10 and 15% ($25^{\circ}C$, 7 days). The pH of the batter prepared with the aged garlic ranged between 6.79 and 7.01 and the control pH was 7.21. The specific loaf volume of the pound cake prepared with the addition of 5~15% aged garlic decreased, from 2.78 to 2.51 cm3/g. The baking loss rate of the pound cake prepared with 0~15% added aged garlic also decreased by 6.91~6.42%. The lightness, redness, and yellowness values of the pound cake decreased with increases in the percentage of aged garlic. The adhesiveness, gumminess, and chewiness of the samples did not differ significantly with differing amounts of added aged garlic. DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity, however, was improved significantly via the addition of aged garlic. In the sensory evaluations, the pound cake prepared with 10% added aged garlic received higher acceptance scores for the properties of smell, taste, softness, moistness, adhesiveness and overall acceptability. Consequently, the optimal quality achieved in this set of experiments was with a pound cake to which 10% aged garlic had been added.

BACKGROUND/OBJECTIVES: In Korea, studies of diet in elementary school children are hindered by the need for a comprehensive dietary assessment tool. Thus, the aim of this study was to develop a semi-quantitative food frequency questionnaire (FFQ) for Korean elementary school children. SUBJECTS/METHODS: The 24-h recall data for 1,624 subjects aged 6-11 yrs from the seventh Korea National Health and Nutrition Examination Survey were used to extract the items included in the questionnaire. The FFQ items were developed by selecting major dishes based on the results of nutritional contribution and between-person variability for energy and 14 nutrients (carbohydrate, protein, fat, crude fiber, calcium, phosphorous, iron, sodium, potassium, vitamin A, thiamin, riboflavin, niacin, and vitamin C). We selected the major dishes with over 90% of the total contribution to each nutrient and with over 90% of the accumulated R² for each nutrient. Among the 452 dishes, we selected 248 dishes contributing more than 1% of the total consumption. RESULTS: Finally, the FFQ included 107 items combined from 248 dishes based on nutrient profile and recipe. The FFQ items accounted for an average of 88.6% of the energy, 14 nutrient intakes, and 91.4% of the between-person variability. Quantities of dietary intake were assessed by 9 categories of frequency and 3 categories of portion size. Percentages of coverage for energy, protein, fat, carbohydrate, and calcium were 90.2%, 87.8%, 89.9%, 90.8%, and 88.7%, respectively. CONCLUSIONS: We developed a dish-based, semi-quantitative FFQ comprising 107 items for Korean elementary school children aged 6 to 11. Further studies are needed to evaluate the reproducibility and validity of this FFQ for elementary school children.

This study conducted an analysis of the middle aged women whose ages are from 35 to 59 years old in order to give those ladies much external satisfaction and covered body lines. I have come to present a few characters of body types as silhouettes which resulted in the factors of the upper bodies of middle aged women. I have adopted SAS(statistical analysis system) as a data process method of this survey. The followings are the results analysis. 1. The item of height have decreased, but increased in the items of thickness among the late middle aged women. 2. The body componant factor of middle aged women are extracted as 10 items, and the rate of their cumulative contribution is 78.9%. The first is the thickness of upper body, the second is the thickness of side upper body, the third is the height of upper body, the fourth is the length of upper body the fifth is width of upper body, the sixth is the projected rate of back, the seventh is the projected rate of breast, the eighth is the squared rate of shoulder, the ninth is the crooked rate of neck, and the tenth is the upper from of breast. 3. The body types of middle aged women can be classified into 4 types, and the followings are their characters. Type 1 is a standard type as the most common body character of the middle aged women, showing the appearing rate of 42.4%. Type 2 is a semi-curved body type like the curved figure of side body, showing the appearing rate of 34.5%. Type 3 is a reverse body type with the projected breast feature of front body, showing the appearing rate of 20.9%. Type 4 is a crooked body type with a tall height and crooked neck, showing the appearing rate of 2.2%.

Undernutrition could be a significant deterrent to healthy aging and could negatively affect health outcomes in elderly. This study aimed to assess health-related factors which are associated with nutritional risks in middle-aged and elderly individuals by a cross-sectional study. Interviews were conducted with 2660 subjects (847 males, 1813 females), aged 50 years and over, in 15 cities in Korea. Data on food intake were obtained through a validated semi-quantitative food frequency questionnaires. Nutritional status were analyzed according to health-related factors including cigarette smoking, alcohol drinking, exercise, stress and depression level. Less regular exercise was associated with a higher likelihood of a poor nutrition [odds ratio (OR) 1.94; 95% confidence intervals (CI) 1.43-2.65] of middle-aged and elderly male subjects. Cigarette smoking (OR 1.84; 95% CI 1.24-2.71), less exercise (OR 2.58; 95% CI 2.07-3.21), stress (OR 1.73; 95% CI 1.36-2.22), and depression (OR 1.34, 95% CI 1.08-1.67) of middle-aged and elderly female subjects was associated with a higher likelihood of a poor nutrition. The results of the multiple regression analysis showed that less exercise proved to be the strongest predictors for the poor nutrition, followed by stress, smoking, and depression (model $R^2= 9.0%$). It suggests that guidance to promote regular exercise, to quit smoking, to minimize stress and depression level might help to improve nutritional status of middle-aged and elderly in Korea. These findings also suggest that having recommendable health behaviors are beneficial to the good nutrition of subjects aged 50 years and over.
