The purpose of this study was the discrimination of different tobacco types by the E-Nose/tongue and the analysis of what human sensory attributes are correlated with e-instrument's sensors. Samples were made from five groups of Korean domestic tobacco leaves, aged burley and not aged, aged flue-cured and not aged and blending types of the four. Instrumental tests were conducted to discriminate characteristics among different tobacco samples by the E-Nose and the E-Tongue. Sensory attributes of tobacco tastes were impact, irritation, bitterness, hay-like, tobacco taste, smoke volume, smoke pungent and mouth cleanness. STATISTICA software was used to analyze correlation between the human sensory data and the raw data of e-instruments. Discrimination analysis can be achieved using principal components analysis (PCA) and discriminant factorial analysis(DFA). As a result, impact, bitterness, irritation, smoke volume and smoke pungent of human sensory attributes were correlated with data from the several clustered E-Nose sensors(p < 0.10). And bitterness, irritation, and smoke pungent of human sensory attributes were correlated with data from the E-Tongue sensors(p < 0.10). PCA plot by the E-Nose shows that aged tobacco and not aged were discriminated and DFA plot shows that three groups(aged burley, not aged burley and flue-cured) were discriminated. PCA plot by the E- Tongue shows that flue-cured tobacco was separated from burley. Our results indicated that the e-instruments are sensitive enough to distinguish among tobacco types and their several sensors are reacted to the human sensory attributes.

The purposes of this study were to identify the household's financial status by life cycle stage and no analyze contributing factors to financial planning for retirement preparation among Korean marred couples. For these purpose, 2074 married couples those being under 55 and having either single earner or dual earners were selected, and total sample was divided into three stages; young-aged(＜35), middle-aged(35-44) & old-aged(45-54). Statistics were frequencies, means, percentile, and logistic analysis. The results were as follows. First, old-aged had higher level of total income, total expenditure and total assets than either young-aged or middle-aged. In addition, households those holding private pensions were likely to have higher total income, total expenditure and total assets than those owning no private pension. while middle-aged had a highest total debts. Second, gini coefficients of total income and total expenditure between three aged groups were similar, but old-aged had the highest gini coefficient of total assets and total debts. In particular, gini coefficients of total assets and total debts of households those having no private pension were greater than those holding private pensions. third, contributing factors to private pension ownership of young-aged were family & household-related factor and financial factor, middle-aged's factors were household head's characteristics and financial factor. Also, old-aged's factors were household head's characteristics, family & household-related factor and financial factor.

Though the growth rate of the population of aged people in Korea is rapidly rising, research about this age group is relatively scarce compared to those about younger groups. This paper aimed to survey the clothing purchasing behaviors and clothing dissatisfaction of the aged women in Korea. A questionnaire concerning demographic status, clothing purchasing behaviors and clothing dissatisfactions was administered to 430 aged women residing in Seoul. Results showed that the aged women are as much well-planning, logical, and consumer-right-conscious purchasers as they are aesthetically demanding. 9 factors including product quality, design, sales service qualities revealed to be important factors explaining their dissatisfaction. But the strongest clothing dissatisfactions of the aged women were found to be those factors related to high price, lack of exclusive merchandising practices for the aged, and difficulty in the handling of clothing items. Their age and income status had partial influence on their purchasing behaviors and clothing dissatisfaction.

The purpose of this research was to identify arid to compare stereotypes toward the elderly held by adolescents and middle-aged adults. Stereotypes toward the elderly were examined at two levels: to assess students′and middle-aged adults′beliefs about the traits of the elderly and to categorize the traits into stereotypes. Traits groupings were analyzed with hierarchical cluster analysis. The main results of this study were as follows: First, both adolescents and middle-aged adults believed the negative stereotypes were more characteristic of the elderly than the positive ones. Second, middle-aged adults reported more complex negative stereotype sets of the elderly than adolescents. Third, Adolescents reported even more negative physical appearance trails of elderly persons than the middle-aged. Fourth, the traits endorsed as characteristics of elderly persons were often contradictory within two age groups. For example, adolescents perceived "sacrifice" as a positive trait of the elderly, while middle-aged adults perceived it as a negative one.

This study was performed to investigate the influence of dietary fibers on the serum lipid level and bowel function in aged rats. Fiber sources of experimental diets were made from mugwort(M), butterbur(B), apple(A), sea mustard(S) by drying and milling. Each of fiber sources was mixed into the diet at the level of 5, 15% of diet. Sprague-Dawley strain, 13 month old male rats were divided into 9 groups by randomized complete block design : C, M5, B5, A5, S5, M15, B15, A15, S15. The animals were fed ad libitum each of experimental diets for 4 weeks. Control group showed lower food intake compare to the other groups. There were no significant difference between 5% groups and 15% groups in food intake. Fecal weight, dry fecal weight and fecal water content of control group were significantly lower than those of experimental groups, and fecal water content was increased by increasing level of dietary fibber. Apple group showed the lowest values, sea mustard group showed the highest. The shorter transit time was observed in the group of higher intake of dietary fiber. At the same level of dietary fiber, transit time of sea mustard group was shorter than the other groups. With increasing age, serum triglycerides, total cholesterol were increased and HDL-cholesterol was decreased. Fiber fed groups showed lower serum TG, TC and higher HDL-c level compare to the control group. Absorption rates of calcium, magnesium and phosphorus was tend to be lower in the group fed dietary fiber sources than control group. Mucosa weight and maltase activity in the small intestine were decreased by increasing age. As intake of dietary fiber increaed, mucosa weight in the small intestine was not different but maltase activity was decreased.

This study analysed the income-related health inequality of the aged in Korea applied to EQ-5D. Two decompositions were used in analysis. One was the decomposition of income-related health inequality into six different dimensions of EQ-5D, and the other was to decompose it by sub-group such as sex, region, existence of spouse. The results are summarized as follows. First, the health concentration index(CI) of the aged was .0254, which meant that there were pro-rich inequality in elderly people's health levels. The same patterns were also seen in the analysis of different dimensions of EQ-5D such as mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Second, mobility accounted for 35.8% of total EQ-5D score, most contributing to CI of the dimensions of EQ-5D. The CIs by the dimensions ranged from .0091 for mobility to .0013 for self-care. Third, The decompositions by sub-groups showed that the contributions of sex, region, and existence of spouse to health inequality was similar to each other, all of three sub-groups accounted for 10 % of inequality respectively. Fourth, the inequality within group was higher in female group, rural area, and the aged without spouse. The average health level of these groups was lower than that of the other ones, too. These facts indicated that old women, the aged without spouse, and the elderly in rural area were the most vulnerable groups in health problems. Therefore, it is necessary to pay more attention to health problems of these groups in the policy making of health security and social welfare services.

Background: The purpose of this study was to identify the association between participation in social activities and mortality rates for those aged 45 aged and older in Korea. Methods: In this study, the 1st to 6th Korea Longitude Study of Aging was used to analyze 10,217 people excluding missing values among middle and old age groups aged 45 or older. The scope of social activities was classified into "religious gatherings," "religious gatherings," "leisure/cultural/sports-related organizations," and "clubs/hometowns/religious associations," and analyzed using a chi-square test and Cox proportional risk model. Results: In the case of non-participating groups in religious activities, the mortality rate was 1.24 times higher (hazard ratio [HR], 1.24; p=0.000) than those of the participating group. The non-participating group of social gatherings had a 1.27 times higher mortality rate (HR, 1.27; p<0.0001) than the participating group. In addition, the mortality rate of non-participating groups related to leisure/cultural/sports was 1.79 times higher (HR, 1.79; p=0.000). The mortality rate of the group that did not participate in the alumni association/festival/folklore society was 1.51 times higher than that of the participating group (HR, 1.51; p<0.0001). As a result of correcting the control variable to analyze the relationship between the number of participants in social activities and the mortality rate, the mortality rate of the group participating in one or less social activities was 2.26 times higher (HR, 2.26; p<0.0001) compared to the four or more social activity participating groups, and the mortality rate of the 1-3 social activities was 1.64 times higher (HR, 1.64; p<0.0001). Conclusion: As a result of the study, it was found that participation in social activities of the middle-aged and elderly groups was effective in reducing mortality, and in particular, it was found that there was a strong relationship with mortality in less than one social activity group. Therefore, it is intended to provide an academic basis for lowering the mortality rate of the group in line with the continuous improvement of domestic social activity participation conditions, and through this, this study can be expected to serve as a policy and institutional basis for lowering the mortality rate of the group.

Purpose: This study aimed to examine factors influencing health-related quality of life (HRQOL) and compare them between young-aged and old-aged patients with cancer. Methods: Data of 291 patients (young-aged: 168, old-aged: 123) were obtained from the 10th wave of the 2015 Korea Health Panel Survey. The HRQOL was measured using the Korean version of Euro-QoL-5D. Independent t-test, analysis of variance, and multiple regression analysis were performed to identify factors influencing HRQOL. Results: The average HRQOL score was 0.87±0.10 and 0.82±0.15 among young-aged and old-aged, respectively. The factors differed partially between the two groups. For young-aged, the influencing factors were activity restriction, subjectively perceived health status, and smoking. For old-aged, the influencing factors were activity restriction, subjective health status, and unmet healthcare needs. Conclusion: Strategies to improve the HRQOL of elderly adults need to be developed considering the age group. Additionally, studies that include clinical factors such as symptoms are required to prepare need-based practical approaches for better quality of life of such patients.

Working towards the compression of morbidity, we attempted to find the way to contribute to desirable aging and/or healthy old age. By looking into the factors affecting nutrient intake in middle-aged adults, we sought to find ways to improve their health status, Two hundred and fifty middle-aged adults from 40 to 60 years of age residing in Seoul and its vicinity were recruited for the survey. Subjects were interviewed for general characteristics, dietary habits lifestyle, status and food intake by a trained interviewer. Two -day food record was included in addition to the 1 -day 24 hr recall. Date were analyzed for the relationship among nutrient intake, health status, socio-economic status dietary habits and lifestyle using a statistical program (SAS) Although the mean energy intake of the subjects did not reach the recommenced dietary allowances(RDA), mean protein intake was well above the RAD for both sex groups(111.2% and 129.1% for men and women, respectively) The caloric contribution of fat was 15 to 20 % of total energy intake among different groups. Riboflavin was the most deficient nutrient and its mean intake reached only 71.0% of RDA for mean This seemed to be due to the lower intake of milk and dairy products among middle-aged Koreans who are more accustomed to traditional meals. Income and exercise habit were the most important factors influencing the nutrient intake of middle-age adults. Also, BMI, smoking habit, level of education regularity of meal, and hours of sleeping influenced the nutrient intake, In conclusion, middle-age adults appeared to have similar problems with the elderly in terms of nutrient intake and this age group should to included when considering nutritionally vulnerable groups in addition to the elderly and young children. The improvement in the nutrition status of middle-age adults is even more important because that could lead into the better health the elderly.
