With increasing elderly living with diabetes, health professionals have focused on the relations between behaviors improving health status and life satisfaction. This research attempts to explain the influence of the health promotion behaviors on the life satisfaction of the elderly with diabetes. Also, we are focusing whether there is a mediating effect of depression between health promotion behaviors and life satisfaction of the elderly with diabetes. 685 persons with diabetes over 60 years of age were selected from the data of KLoSA (Korean Longitudinal Study of Ageing), administered by The National Institute of Labor in 2006. Life satisfaction was measured by 5 items: health status, economic status, relationship with a spouse, relationship with children, and the quality of life. Health promotion behaviors were measured by 4 items: regular diet, exercise, smoking, and drinking. The mediating variable is the depression measured by CES-D10. As the method of analysis, the multiple regressions were used with SPSS 12.0. The result of the study shows that the health promotion behaviors have a positive influence on life satisfaction and a negative influence on depression. It was also verified that the depression variable has a partial mediating effect between health promotion behaviors and life satisfaction. These results present the importance of integrated (physical, psychological, and social) approach for the health promotion experts intervening with the elderly with diabetes.

The objectives of this study were to examine how social networks of old retirees impact on their retirement satisfaction, and through this, to suggest ways of improving their retirement satisfaction. Data used in this study were from 2006 KLoSA(Korean Longitudinal Study of Ageing), which were collected from 1,009 elderly people aged 65 and over who resided metropolis and smaller medium cities and answered regarding their retirement satisfaction. Data were analyzed by Binary Logistic Regression method. As a result, the frequency of contact with children, the number of participation in their social activities, and the satisfaction of relationship with children were the significant variables to predict retirement satisfaction. In addition, other variables such as gender, subjective health status, type of retirement, and duration of past retirement have been found as significant variables to explain retirement satisfaction. Implications for designing effective retirement plan and service systems have been discussed.

The goal of this study was to examine the association between employment and depressive symptoms among older adults in Korea, including analysis of potential gender differences. Using a sample of Korean adults aged 60 years or older from the 2008(Time 2) and 2010(Time 3) national longitudinal survey data from the Korean Longitudinal Study of Ageing, we regressed measures of depressive symptoms at Time 3 on employment at Time 2 (and employment both at Time 2 and Time 3), controlling for Time 2 depressive symptoms, subjective physical health, and sociodemographic variables as well. First, there was no evidence that older adults with a job at Time 2 had significantly lower levels of depressive symptoms at Time 3 compared to their counterparts. However, multi-group analyses showed that the effect of employment at Time 2 on depression at Time 3 differed by gender. For older men, employment predicted better mental health over time. However, this was not the case for older women. As such work role provided benefits only for older men. Second, older adults with a job at both Time 2 and Time 3 reported significantly lower levels of depressive symptoms at Time 3 than older adults who did not have a job either at Time 2 or Time 3. However, only older men who were employed at both Time 2 and Time 3 reported significantly less depression than their counterparts. These findings suggest that the mental health effects of employment are contingent on gender.

In the situation providing the aged society, the contents of the symptoms of senility centering around the aged-pulse condition were arranged. The results were as follows. In the questions about the aged symptoms, the results of indicating the gradual physical-age following the aged symptoms with the real age(from 40 to 100, 7 grade) and the gradual physical-age following the ageing grade of male and female (the 3 grade of the female / the 4 grade of the male) could have the differentiations. And the distinction of the aged pulse condition was observed two pulse condition ; the one is the minute pulse condition(Mi, Sei ;微細) as lowering function and the other is the Hyun, Ghin(弦, 緊) pulse condition as the blood's tention and contration.

Objective:The objective of this study is to apply the principals and policies of universal design to offer a safe and efficient workplace for older workers. Background: The concept of universal design has rapidly developed under the paradigm that tasks should be easy and comfortable for all people with diverse features. The concept is also fitting when designing a workplace. Method: Legislations, policies and precedents of workplaces with older workers have been studied and analyzed. The compilation has been used to project the present and future of employing universal design at workplace devisal. Results: Every country has its own legislations/policies regarding universal design, flexible working, and age-friendly workplaces to increase hire of older workers. The basic concept of UD and its application is explained. This study provides guidelines for employing universal design at workplaces and preventing accidents for older workers. Conclusion: Following the principals of universal design is expected to furnish a comfortable and safe workplace and lengthen the period of workers participating in the labor force in an ageing society. Application: This study offers the principles for universal design, serving as fundamental research for its application to the workplace.

A rapid decrease of total fertility rate to 1.08 in 2005 prompted the Korean government to plan and implement a '5-year plan for ageing society and population policy' starting from 2006. The 1st and 2nd 5-year plans had not shown any discernible impact on the fertility and the 3rd 5-year plan was launched in 2016. However, the fertility rate is going down further. The author reviewed the contents and assessment reports of the fertility promotion plan to suggest ideas for complementing the shortcomings of it. Author defined the major determinants of marriage and child birth as philosophy, politics, sense of value, social norm, culture, healthcare, and education. The plan was examined in view of these determinants. Transformation of Korea from an agricultural society to an industrialized society in a short period of time had brought about changes in most of the determinants of marriage and child birth; in particular philosophy and sense of value. These aspects were not put into consideration in the plan. Author suggested to launch a social education program for the general public to establish a sound philosophy of life, reform the sense of value on family, child birth and education, and cultivate the skill to draw a consensus through discussions on the social issues. A special program to promote marriage of women at the optimum age for child birth was proposed. The government should implement well balanced policy for economic development and labor. Multidisciplinary approach was recommended for these tasks.

Skin ageing is associated with compromised performance of its fundamental barrier functions, with undesirable changes in appearance. Since this may introduce a detrimental impact on the quality of life, significant effort to discover effective ingredients against ageing is being invested. Recently, collagen hydrolysates containing tripeptides such as GlyPro-Hyp (GPH) have been developed with anticipation of improved effects compared to that of existing collagen hydrolysate-products. To evaluate the cutaneous hydration effect of collagen tripeptides (CTP), meaningful biomarkers in human dermal fibroblasts (HDF) and NC/Nga Tnd mice were analyzed in this study. Increased levels of ceramide kinase, hyaluronic acid, collagen 1A, and hyaluronan synthase-2 (HAS2), and decreased levels of hyaluronidase-1 (HYAL1) and CD44 in HDF cells were demonstrated. Furthermore, significant reduction of transepidermal water loss (TEWL), scratching behavior, HYAL1, $TNF-{\alpha}$ and IL-6 and increased water content and HAS2 were verified by in vivo tests. These results strongly suggest the potential of CTP as a skin hydration agent.

The study was conducted to investigate the effects of practical variations in feed restriction, pre-slaughter handing and chilling regime on pork quality during ageing. A total of twenty male landraces were allocated into three treatments(i.e., pre-slaughter feeding, stress and chilling regime) in a factorial arrangement. pH, temperature, free calcium ions, WB-shear force, sarcomere length, cooking loss, drip loss and objective color were determined during rigor development and/or 1, 3, 7 d postmortem. Pre-slaughter chasing stress for approximately 15 min had no effects on pH/temperature profile and objective meat quality. There was an interaction(P < 0.05) between the fasting treatment and chi1ling regime for muscle temperature at pH 6.2. Sarcomere length indicated that the current experiment conditions did not induce muscle shortening, with 1.7 to 1.8 ${\mu}m$, in spite of a significant effect of the fasting treatment (P<0.01). Pigs fed until the morning of slaughter showed a low WB-shear force(P < 0.05) until 3 d at I "C. The treatment also resulted in a higher Hunter L* and a*(P < 0.05) at 24 h and 7 d. Fasted pigs showed a significantly(P < 0.05) reduced cooking loss. The current results indicated that feeding upon the morning of slaughter became detrimental on meat color and the negative effect on cooking loss were linearly elevated with increased ageing time. On the other hand, WB-shear force did not distinguishable after 3 d. Collectively, it appeared that feed restriction from a day before slaughter could produce more a desirable meat quality at the time of consuming. However, the limited effect of animal handling and chilling rate on meat quality is not necessarily to extend to that these do not affect pork quality, as that largely depends on experimental design.

The purpose of this study was to investigate the clinical results of the 10 male climateric syndrome cases while treated with Singi-hwan. All patients were treated with Singi-hwan two times a days for 5 weeks. We checked testosterone, PSA in blood, HRV and AMS questionnaire score. The questionnaire score was improved after taking Singi-hwan. Stress resistance and autonomic nervous system activity is increased, but there was no statistical significance except for ApEn. Taking Singi-hwan did not affect the serum concentration of testosterone, PSA and blood biochemical tests. The next placebo-controlled studies about late onset hypogonadism treated with Singi-hwan are needed.

This study was carried out to investigate the effects of high temperature and humidity on the ageing of processed leaf tobacco. Four(1993) or six(1994) grades (Both flued-cured and burley) of processed leaf packed in carton box were stored under the natural and artificial conditions. When the Processed leaf was stored in the controlled mom at 40℃ with 75% R.H.(1993) for 40 days, the leaf pH was decreased. The decreasing rate of leaf pH was similar to that of leaf stored under the natural warehouse condition for 15 months. The degree of lightness and yellowness of leaf also decreased, while the decaying or darkening of the leaf was observed. When the processed leaf was stored in the controlled room at 35℃ with 65% R.H.(1994) for 90 days, the pH of flue-cured was decreased 0.22, which was similar to that of the leaf stored under the natural warehouse condition for 15 months, and the lightness, and redness of the leaf were higher than those of the control. As compared with the leaf stored under the natural condition for 2 years, the smoking quality of leaf stored under this condition was similar or somewhat better. The pH of burley tobacco changed little compared to that of flue-cured during storage in this study.
