The purpose of this study is to examine whether middle-aged people's anxiety about economic well-being in old age affects problem drinking and to verify whether there is relationship between anxiety about economic well-being in old age and to examine the problem drinking could be mitigated by social supports. We used the 2015 Korean Adults' Psycho-Social Anxiety Survey data. To detect the moderating effect of social supports, we employed a method of hierarchical multiple regression analysis. The result of the study showed that the higher the anxiety about economic well-being in old age among middle-aged adults, the higher was the likelihood of problem drinking. Moreover, the relationship between anxiety about economic well-being in old age and problem drinking could be moderated by social supports. Based on the empirical findings, this study suggests that education to deal with middle-aged people's anxiety about economic well-being in old age should be developed and recommends that counseling and community programs for social supports to be implemented as a preventive approach.

This study was conducted to offer basic data that can be used in a clothing industry for active senior males that are emerging as a new consumer bracket in a rapid aging age. To this end, this study conducted an analysis of 'younger' older male body types based on data from the 6th Size Korea. As a result of the body type analysis of 'younger' older males who are considered active seniors in comparison to 'middle' aged males, the former's height items became shorter compared to 'middle' aged males, but circumference items were bigger. Males aged 35-69, who are 'middle' aged males and 'younger' old males were divided into three body types in this study: Type1- small body type with protruded belly, compared to weight. Type 2- body type of slim torso with wide shoulder-back widths. Type3- big body type overall with tall height and heavy weight. According to body type distribution by age group, the middle-aged males had Type2 body type the most. The younger-old males showed type1 the most. There is a need to reflect the body types of active senior male characteristics in apparel pattern design because the current fits are not appropriate if active senior males wear clothing targeted for males aged 30-50.

The aging of society is not only Korea's challenge but also a global issue. This leads to an increase in the number of elderly drivers who are much more prone to major traffic accidents. Therefore, we need a system to test aged drivers' driving abilities. As part of efforts to establish such a system, researchers of KoROAD. have conducted a study on the correlation between aging and driving abilities by analyzing old drivers' reaction time. The study shows that there was a sharp increase in reaction time for drivers aged 65 and over. The current reaction time of 2.5 secs for the 85 percent of eligible drivers needs to be revised upward in aging societies. From now on, we need to come up with the traffic safety measures that can deal with the issue of drivers of old age.

The purpose of this study is to explain. It also examines and compares factors influencing life satisfaction among the middle-aged at various income levels. The data source for this study was the third additional wave and the fourth wave of the Korean Retirement and Income The study sample consisted of 1,723 middle-aged (age 50-64) individuals. The data analysis methods included the chi-square test, ANOVA, and multiple regression analysis. The results were as follows. First, there was a positive relationship between old age preparation and life satisfaction. Second, it was found that old age preparations (physical, emotional, social, financial) and life satisfaction show meaningful relationships among the income levels. Third, old age preparation was found to have different meaningful impacts on life satisfaction among the income levels. The results of this study verify the degree of the relationship between old age preparation and life satisfaction and the different impact factors relating to old age preparation for life satisfaction among the income levels.

The purpose of this study was to develop a nursing model for the aged. This study was conducted to measure the physical, psychological and mental health status of the aged and to identify relationships between these health levels and various variables. The data were collected from 172 aged(over 60 years old) by interviews. The tools used for this study was a structured questionnaire which was developed and revised by the researchers. The tool consisted of 22 items on physical health assessment, 7 items on psychological health assessment, 9 items on mental health assessment and 10 items on an ADL evaluation. The major results of the study were as follows ; 1. In physical health, the aged complained of visual disturbance(60.5%), incontinence of urine (55.2%), back or muscle pain(73.3%), dizziness(70.3%) and diarrhea or constipation(44.2%). In psychological health, most aged people felt anger when they got some order from an other person(80.2%). Also, they had depression (69.8%) and felt like dying(64.0%). The ADL level was mostly normal for daily life. 2. The aged man was more healthy than the aged woman in physical and mental health especially the 60-64 year old group. The physical, mental health and ADL level had a positive correlation with age(p>.004), but psychological health had a negative correlation with age. 3. The physical, psychological, mental health and ADL level was positively interrelated with each other. 4. The physical, mental health, & ADL level lowered with inceasing age. Physical & psychological health worsened rapidly from 65-69 years, but for 10-15 years, their health level was preserved. Psychological health level was high in 80-84. 5. The physical health was affected by edu cational level, sex and pocket money (R=.4029, 16.24%). The psychological health was affected by the supportive style and pocket money (R=.5128, 26.30%). And the mental health was affected by education level, age, support ive style, sex and job(R=.4377, 19.16%). As seen above, we suggest the intervention of the young for the old to cope with their life and to maintain their healthy late adulthood. Also, if they have received psychological support in the institution, they will maintain healthy life condition. For further studies should be a search for variables that affect aged health, and should contribut to a nursing program better suited for the aged.

Objective: The objective of this study was to compare the quality of dry-aged beef from cull Hanwoo cows slaughtered at 60 or 80 months old. Methods: A total of eight cull Hanwoo carcasses with a quality grade of 3 (low-grade) were selected and divided into two age groups: 63.5±2.5 months old (n = 4) and 87.8±4.5 months old (n = 4). Whole longissimus thoracis et lumborum from the 11th rib to the last lumbar vertebrae, including the back fat, was removed from the carcass at 24 h postmortem and aged for 50 days in darkness at a temperature of 2℃±1℃, a relative humidity of 85% and an air flow of 2 m/s. The sampling was performed aseptically after 0, 20, 24, 40, and 50 days of aging. Results: Regardless of the aging period, aging increased the lightness (p<0.05), redness (p<0.05) and yellowness (p<0.05) at initial blooming (90 min after slicing) and the overall acceptance (p<0.05). No further tenderization effect was found after 20 days of aging, but aging for 50 days significantly increased the lipid oxidation (p<0.05). The generation of aroma volatiles in the roast steak from aged samples was higher (p<0.05) than that of non-aged samples. No significant effect of age at slaughter was found on the color, pH, water-holding capacity, cooking loss, shear force value, bacterial counts, volatile basic nitrogen, consumer acceptance, lipid oxidation, fatty acid composition or aroma volatiles. Conclusion: The quality of dry-aged beef obtained from cull Hanwoo cows slaughtered at either 60 or 80 months old with similar quality grade was comparable and extending dry aging for more than 40 days is not recommended considering the costs and further lipid oxidation.

The number of reporting the effects on ginseng's physiological, pharmacological, and behavioral effects has been increased every year. Major active components of Panax ginseng, are the ginsenosides, which are mainly triterpenoid dammarane derivatives. 3-Nitropropionic acid (3-NP) is blown to induce cellular energy deficit and oxidative stress related neurotoxicity via an irreversible inhibition of the mitochondrial enzyme succinate dehydrogenase (SDH). Intraperitoneal injection of 3-NP produces striatal degeneration. Aged animals was more vulnerable to 3-NP than young animal. We used three different ages of 5-, 8-, and 26-week-old rats. 3-NP alone treatment induced striatal lesion and increased lesion volume with age-dependent manner in 5-, 8-, and 26-week-old rats by $30.2{\pm}5.8$, $v$, and $51.3{\pm}8.4mm^3$, respectively. However, pretreatment of GTS (100 mg/kg/day) before 3-NP reduced striatal lesion in 5-,8-, and 26-week-old rats by $3.15{\pm}6.1$, $8.89{\pm}1.9$, and $27.3{\pm}5.6mm^3$, respectively. Pretreatment of GTS also significantly increased survival rate in 5-week-old rats (3-NP alone: GTS +3-NP = $40.4{\pm}6.3$: $72.5{\pm}9.5\%$) than 8-week-old rats (3-NP alone: GTS + 3-NP : $13.5{\pm}5.2\%$ : $45.1{\pm}3.1\%$). In 26-week-old rats, 3-NP alone treated group died on day 18, whereas GTS +3-NP-treated group prolonged lifespan to 30 days. Thus, pretreatment of GTS before administration of 3-NP extended lifespan in all ages. The present results indicate that aged animals are more vulnerable to 3-NP and GTS pretreatment protected 3-NP-induced striatal damage in different ages of animals.

Objective As aging progresses, clinical characteristics of elderly patients in the emergency department (ED) vary by age. We aimed to study differences among elderly patients in the ED by age group. Methods For 2 years, patients aged 65 and older were enrolled in the study and classified into three groups: youngest-old, ages 65 to 74 years; middle-old, 75 to 84 years; and oldest-old, ${\geq}85years$. Participants' sex, reason for ED visit, transfer from another hospital, results of treatment, type of admission, admission department and length of stay were recorded. Results During the study period, a total 64,287 patients visited the ED; 11,236 (17.5%) were aged 65 and older, of whom 14.4% were 85 and older. With increased age, the female ratio (51.5% vs. 54.9% vs. 69.1%, P<0.001), medical causes (79.5% vs. 81.3% vs. 81.7%, P=0.045), and admission rate (35.3% vs. 42.8% vs. 48.5%, P<0.001) increased. Admissions to internal medicine (57.5% vs. 59.3% vs. 64.7%, P<0.001) and orthopedic surgery (8.5% vs. 11.6% vs. 13.8%, P<0.001) also increased. The ratio of admission to intensive care unit showed no statistical significance (P=0.545). Patients over age 85 years had longer stays in the ED (330.9 vs. 378.9 vs. 407.2 minutes, P<0.001), were discharged home less (84.4% vs. 78.9% vs. 71.5%, P<0.001), and died more frequently (6.3% vs. 10.4% vs. 13.0%, P<0.001). Conclusion With increased age, the proportion of female patients and medical causes increased. Rates of admission and death increased with age and older patients had longer ED and hospital stays.

Purpose: This study is to verify and analyze the influencing factors of successful aging with social support, self-efficacy, community environment and subjective health status on middle and old aged men. Methods: The survey was performed to the men between the ages of 50 and 79 in Seoul and Kyunggi province, Korea. 144 questionnaires were collected and analyzed by SPSS 18.0 program. Stepwise multiple regression was used to identify significant predictors of successful aging. Results: The most influencing factor for successful aging was social support, the second was self-efficacy, the third and the fourth was community environment and subjective health status. This regression model explained 56.7% of the variance in successful aging. Conclusion: The result shows that these variables should be considered in intervention and program of successful aging for middle and old aged men. It can be an important consideration in enhancing promoting care and welfare for the successful aging.
