1. Objectives Sasang constitutional medicine is unique in Korean traditional medicine. It diagnoses and treats patients based on his/her Sasang constitution (SC). Skin properties have been used as an effective diagnostic component in the classification of SC types in clinics. In this paper, we investigated the SC-based health relevance of skin elasticity and wrinkle properties. 2. Methods The skin elasticity and wrinkle of forearm and dorsal hand were measured in 299 elderly female subjects. To determine the subject's Sasang constitution, we adopted the classification results from a newly developed SC diagnostic tool. The health states of the subjects were scored by two Korean traditional medical doctors, by whom each subject was categorized either into the healthy state or the unhealthy state. 3. Results As a result, the elasticity hysteresis of forearm (E_HYS), the visco-elasticity (VE_MEAN), and the wrinkle frequency energy of backhand (W_HAND) showed significant differences between Taeum-in group and Soeum-in group. In case of the Soeum-in on unhealthy state, VE_MEAN was decreased significantly (p<.05). W_HAND and W_ARM_H of the healthy Taeum-in were less than those of the unhealthy Taem-in. 4. Conclusions In this study we showed that, for an elderly female population, skin elasticity and viscosity were significantly different not only between each SC type but also between healthy group and unhealthy group in each constitution. In particular, Soeum-in subjects were inferred to be superior in retaining skin softness when they were healthy, and Taeum-in subjects were easy to lose their firmness of skin surface when they became unhealthy.

The objective of this study is to develop a sizing system of fitness clothing that can properly accommodate various body sizes of Korean senior women. The sizing system of upper and lower fitness clothing was developed in the present study by selection of key variables, identification of size category candidates, and determination of an optimal sizing system. First, key anthropometric dimensions (stature and bust circumference for upper clothing and stature; waist circumference for lower clothing) were identified by factor analysis on the direct body measurements (n = 272) and 3D whole-body scan data (n = 271) of Korean senior women in Size Korea. Second, sizing system candidates based on the key dimensions of upper and lower clothing were explored using a grid method and an optimization method. Lastly, among the sizing system candidates, optimal sizing systems of upper and lower clothing were selected in terms of accommodation rate. Five size categories (short/small, short/medium, tall/small, tall/medium, and tall/large) were selected as the optimal sizing systems of upper and lower clothing with 89% and 78% of accommodation rate, respectively, for the Korean senior women. The anthropometric characteristics of the representative humans of the optimal size categories would be of use in the design of fitness compressive wear for the better fit and effectiveness of exercise and health of Korean senior women.

This study was carried out to determine the quality characteristics of grape jellies made with various gelling agents such as agar, $\kappa$-carrageenan, and gellan gum for consumption by elderly women. The concentrations of agar were 0.25, 0.35, and 0.45%, and those of the $\kappa$-carrageenan and gellan gum were 0.15, 0.3, and 0.4%, respectively. The color values, gelling temperatures, melting temperatures, break down rates, textural properties, and consumer acceptance of the grape jellies were measured. The average age of the subjects participating in the acceptance test was 82. The lightness of the grape jelly made with agar was the highest, and its redness was the lowest among the jellies. The gelling and melting temperatures for the grape jelly made with gellan gum were higher than those of the other jellies, and the melting temperatures were 37, 43, and $47^{\circ}C$ based on 0.15, 0.3, and 0.4% gellan gum content, respectively. The break down rate of the grape jelly made with gellan gum was the lowest among the jellies. These results indicate that the stability of the grape jelly made with gellan gum was superior among the jellies. The hardness, adhesiveness, and springiness of the grape jelly made with agar were lowest among the jellies, and the grape jellies made with agar(0.25% and 0.35%) and gellan gum(0.15% and 0.3%) had the highest consumer acceptance among the jellies. However, the gellan gum was deemed an inappropriate gelling agent with regard to the acceptability due to its sour and moldy taste as perceived by the participants.

The share of self-employment shows a downward trend until 1990 and then an upward trend since then. The upward trend is mainly due to more employers and more male self-employed, which implies that self-employment plays a significant role as an alternative form of employment. This paper examines whether self-employment can be a bridge between no work and wage work in the processes entering into or exiting labor market, and if so, what determines the choice of self-employment as a bridge, using the data from the Korea Labor and Income Panel Survey(Wave 1 to Wave 5). Empirical analysis employing the probit model shows that the older, female, the less educated, and persons with bad health are more likely to choose self-employment as a bridge in the exit process and that they are less likely to choose it as a bridge in the entry process. Business cycle has a statistically significant negative effect on its role of bridge employment in the exit process but not in the entry process. The result implies that, in the ageing society, labor market policy should consider self-employment as a better alternative than wage work for the aged.

Objectives Sasang Constitution (SC) is determined by various physical and psychological attributes. Recently, skin properties have been used effectively to describe SC types in clinics. In this paper, we investigated the constitution dependence of skin elasticity and skin perspiration by using quantitative measurement devices. Methods The skin elasticity of forearm and the skin perspiration of forehead and philtrum were measured in 223 elderly female subjects. To determine the subject's constitution, we adopted the classification results from a newly developed diagnostic tool. For the clarity of constitution, we excluded low-scored subjects in their SC classification. Results & Conclusions As a result, the elasticity hysteresis of forearm (EHFa) of Taeum-in group was significantly less than the EHFa of Soeum-in group. Soeum-in group has high perspiration difference between philtrum and forehead (Diff.PhFh) compared to Taeum-in group in a significance level of .05. Taeum-in and Soeum-in group were significantly classified by EHFa and Diff.PhFh using a Support Vector Machine.

Universal designs begins from observing things. This paper understands contradiction and irrationality about drink bottle used unintentionally in our common life. Those have not found out until now. So an example observation about problem derivation and a practice method of Universal design is presented. People of various classes, such as a child, an old person and a woman, a male, the man in the street, and a disabled person, have been using drink bottle recently. However, the design of drink bottle has become on the basis of the fine and common man, so the other people, for example, children or handicapped persons experience many situations which cannot open cap or cannot be drunk without external help. This research posed questions from the children to the elders about drink bottle by the viewpoint of universal design paying attention to such problems. In the research result, the fixed quantity and qualitative quantity about problem are commented. And the fixed quantity utilized frequency analysis and chi-square verification ($X^2$) for the questionnaire result on the basis, and the qualitative quantity pointed out result in the universal design principle through the data of a precedence research result. An alternative plan for drink bottle's design is presented through case observation of conceptual approach to method of Universal design.

In modern society, developing and utilizing safety service and system environments is a very important and great interest. In particular, the provision of safety services to socially vulnerable groups such as children, the elderly, women, the disabled and foreigners has become a social issue. However, since most safety services and systems are applied to the general public, it is necessary to develop systems for socially vulnerable groups. Therefore, in this paper, we developed a system module that processes and transmits data to recognize the situation in real time and respond quickly. To this end, various sensors for real-time situation recognition were designed as integrated modules, and a safety system module was developed to analyze the collected data and transmit the processing results.

The aim of this study was to investigate the association between self-rated oral health, self-rated health, and quality of life (QOL) among older population from the 7th Korea National Health and Nutrition Examination Survey (KNHANES VII-1, 2016). Data of 1,866 older adults (Mean age 69.5 years) were analyzed with hierarchical logistic regression analyses with IBM SPSS 23.0. Over 87.7% of the subjects rated their oral health as fair or poor. Women and less educated participants more likely to report their perceived oral health as poor (p<.05). Older participants who rated their general health positively were more likely to rate their oral health as good (F=19.04, p<.001). Elders who had bad perceived health (OR: 2.86, 95% CI: 1.5~5.5), had carries in permanent teeth (OR: 2.68, 95% CI: 1.67~4.32) and anxiety or depression (OR: 1.45, 95% CI: 1.42~2.57) had negative oral health perception after controlling for covariates. In conclusion, perceived oral health and QOL were associated with each other in Korean older adults. Therefore, it is recommended to approach holistic strategy for improve health and quality of life in the elderly population.

The aim of this study were to evaluate the effect of kinesio taping on isokinetic muscular function and pain of knee joint. The subjects for this study were twelve elderly women($65{\sim}70$years) suffered by knee joint pain over more than three years. The taping methods performed on 3 times a week for 8 weeks for improvement of isokinetic muscular function. Also, the change of visual analogue scale(VSA) and varval rating scale(VRA) has been measured before and post taping 8 weeks. Paired t-test was performed for data analysis at the 0.05 level of significance. After 8 weeks, the results of the study are as follow; First, peak torque, peak torque % BW, total work and ipsilateral balance ratio were significantly improved. And, work fatigue, visual analogue scale and verval rating scale were decreased significantly after 8 weeks taping. The results suggest that applying kinesio taping on knee joint may improve isokinetic muscular function of elderly women. Therefore kinesio taping method was effective for pain relief and prevention of knee joint pain in the elderly women.
