Purpose: Construction sites are currently facing a socialization problem as the incidence of thermal disease-related disasters increases due to summer heat waves, exacerbated by factors like the concentration of middle-aged and older workers and global warming. The reason why construction sites are particularly vulnerable to heat waves is that there are many outdoor work, which is the peculiarity of the construction industry, and most of the construction workers are elderly. This study analyzes disaster statistics of workers at construction sites for five years to investigate the occurrence of thermal diseases and analyze factors through disaster cases to provide basic data for future disasters to be reduced. Research design, data, and methodology: According to the Construction Workers' Mutual Aid Association, as of June, more than 60% of the construction workers working in the field were in their 50s and 60s. More than 24% are in their 60s and older. Thermal diseases caused by heat waves occur when exposed to high heat or strong sunlight for a long time, accompanied by headaches and dizziness. The problem is that many elderly people have underlying diseases, so if they lose consciousness, they cannot easily recover and are likely to die. Results: According to industrial accident statistics, 182 people were injured by heat-related diseases in the summer from 2016 to 2021, of which 29 died. In particular, in the construction industry, which has a lot of outdoor work, 87 people were injured and 20 people died. Conclusions: In order to prevent heat diseases caused by outdoor work, it is emphasized that exposure time is controlled, and sufficient rest and hydration are essential. Rest, water, and shade are in line with the three principles.

PURPOSE: This study compared the effects of indoor and outdoor environmental changes on the activity of the major lower limb muscles and walking factors in people 40-50 years and those aged older than 70 years. METHODS: Ten middle-aged people in their forties (age:$44.2{\pm}2.7$, BMI:$21.8{\pm}1.8$) and 10 elderly aged more than 70 years (age:$76.4{\pm}5.9$, BMI:$22.2{\pm}1.9$) with a normal walking ability were included. The participants walked 100 m both indoors and outdoors at their own speed. Using a 3D motion analyzer and EMG, the walking speed, angle of the ankle and activity changes of the lower limb muscles were compared. RESULTS: Significant differences in walking speed and peak-plantar flexion angle were observed between the two groups (p<.05). The muscular activity of the gastrocnemius muscle (GCM) was significantly different outdoors in the swing phase between the two groups (p<.05). In the people aged in their forties, the muscular activity of the rectus femoris (RF) was significantly higher outdoors than indoors (p<.05). In the elderly, however, the muscular activity of the RF was lower outdoors than indoors (p<.05). When compared to those in there forties, the muscular activity of the outdoor RF significantly decreased in the elderly group (P<.05). The muscular activity of the biceps femoris (BF) in the elderly decreased significantly outdoors compared to indoors (p<.05). CONCLUSION: For the elderly, increasing the exposure to the new environments or focusing on the performance of repeated movements for gradual speed control and precise movements is required to maintain normal gaits and movements that are less affected by environmental changes.

This research was investigated how self-esteem and social support influenced depression for middle-aged and elderly male homeless people in Young-Deung-Po area. By using the sample of 150 male homeless people in Young-Deung-Po area, a multiple regression analysis was conducted for examining the impact of self-esteem and social support on depression. The findings of this study were following. First, self-esteem was a statistically significant indicator for depression. Specifically, the lower level of self-esteem was likely to increase the level of depression. However, social support as another key variable turned out not to be a significant predictor for depression. Second, age significantly impacted on depression for middle-aged and elderly homeless people. The older homeless was, the higher level of depression was indicated. The implication of these results was discussed.

This study was conducted on 878 retired women in their 50s and 60s across the country using the 7th data from the National Pension Service's KReiS. We used SPSS WIN 18.0, and the analysis results are as follows. First, there were many highly educated people in their 50s or older and those in their 60s and undereducated. Second, families in their 50s had the largest number of members with more than three, while households in their 60s had the largest number of two. Third, both age groups chose themselves and their spouses as responsibilities for preparing for retirement. In addition, more people in their 60s chose the government as their responsibility for preparing for retirement than in their 50s. Both people in their 50s and 60s say they are "not prepared" to prepare for retirement expenses, raising concerns about elderly poverty. Fourth, economic strength, health, and medical care were important for retirement in both age groups as part of their preparations for retirement, and they chose economic strength, health, medical care and job as the things to do in society. Fifth, both people in their 50s and 60s have very low public and private pension subscription rates, requiring special attention from the government and society to their old age. Judging from the above results, both women in their 50s and 60s have retired, but preparations for retirement are very insufficient. Therefore, the government and society need to strengthen the public pension system and create jobs for the elderly.

In our increasingly aged society, the term centenarian, meaning people 100 years old or older, is used more and more frequently. Indeed, anticipating long life, middle-aged to advanced-age people have changed their lifestyles to purchase goods for themselves. In addition, as the social trend of careful grooming for positive appearance spreads within the Korean society, the demand for senior male cosmetic products is likely to grow as the society ages further. However, previous large studies on the market for senior male cosmetics are limited. Since information is lacking about senior male consumers' awareness of cosmetics, this study examined their use of cosmetic products, purchase behaviors, and demand for cosmetics in order to explore correlations among interest levels in appearance, cosmetic purchase behavior, and cosmetic demand levels through diverse factors related to multiple variables. The results of this study were as follows : First, the more senior men managed their practical appearance, the more frequent their functional and psychological purchase behaviors. Second, the higher their practical purchase behavior, the stronger their demand for reasonable cosmetic prices. Third, the higher their value-oriented purchase behavior, the stronger the demand for greater product diversity. This study investigated men aged 50 or older residing in Seoul. Therefore, generalizing the findings of this study will be limited. Relevant subsequent studies should examine men aged 50 or older in each Korean region and more clearly identify the correlations among interest in appearance, cosmetic product purchase behavior, and cosmetic product demand using various factors related to multiple variables.

The purpose of this study is to investigate the differences of the factors affecting the entry of depression by generations and to present a practical strategy for preventing of depression by life-cycle. For this purpose, we analyzed the factors influencing the depression of adults, middle-aged and elderly people through the discrete-time hazard model. The results of this study are as follows: First, the lower the self-esteem, the lower the income satisfaction and the family satisfaction people have, the higher the likelihood of entering the depression they have. In addition, age, educational level, health status, presence of chronic diseases, employment status, regional area, and leisure life satisfaction were variables that showed difference by generation. In the case of adulthood(aged 20 ~ 39), unemployed persons are more likely to enter the depression than younger workers. On the other hand, the middle-aged(40 ~ 64 year olds) are more likely to enter the depression if they are older, have poor health status, have no chronic disease, and have low leisure satisfaction. Finally, older people(aged 65 and over) are more likely to enter the depression when the education level is higher, the health condition is worse, and the leisure satisfaction is lower. If they lived in an urban and rural complex, they are more likely to enter the depression. Based on these results, it is necessary to establish a support plan reflecting the characteristics revealed by generations in order to prevent the entry of depression.

Digital accessibility of the middle-aged and elderly has been increasing at a faster pace than other groups such as the handicapped and adolescents. However, studies related to the digital accessibility of middle and older adults are scarce. In order to examine variables affecting accessibility to digital information of the middle-aged and elderly people, this study researches the impacts of sociodemographic, physical and mental health and social activity variables on the accessibility of digital information. We analyzed data of 1,661 people between the ages of 55 and 84 from the 2018 Status Survey on Digital Divide conducted by the National Information Society Agency. The hierarchical multiple regression analysis shows the higher education, economic, and life satisfaction levels are, the higher digital accessibility levels of both male and female are. The result of the analysis also shows that the aged male has a higher accessibility level when he does not live alone; meanwhile, the aged female has higher digital capability as her age is lower, which describes that there are differences between gender. We expect the result of this study to be used as an important reference to understand factors related to digital accessibility level and active intervention for improving digital accessibility of the middle-aged and elderly male and female.

Objectives : The aim of this study was to examine attitudes of middle-school students toward happiness, suicide, and factors associated with suicide. Methods : A self-administered questionnaire was used in a cluster sample of 1,319 middle-school students (male 793, female 526). Data were obtained on a wide range of constructs regarding their attitude towards happiness, suicidal ideation and attempts, and factors associated with suicide. Results : Middle-school students choose 'love within family' as most important factor for their happiness. Subjective mental health status was mostly associated with happiness. Subjects in lower socioeconomic status tended to respond their mental health status was not good and have more suicidal idea. 48.7% of subjects had permissive attitudes toward suicide, especially, girls. However, 65.0% responded that suicide was preventable problem. Compared to older people, middle-school students perceived that environmental factors were more important than innate and personal factors for suicide. Conclusion : Results of the study indicate that middle-school students have permissive attitudes toward suicide, but positive attitudes for the prevention of suicide. This suggest that education in these age group could be effective for the prevention of suicide. Also, approaches to suicide prevention programs should be developed based on the family intervention. Especially, we should care about girls and adolescents in lower socioeconomic status.

This paper empirically estimates the decision of aged workers related to the retirement decision. Using the supplemental survey for aged people of the Korean panel data set, the paper analyses the correlation between the retirement decision of middle-aged people (aged 50 years or older) and personal characteristics and job characteristics of main jobs that aged people had worked, particularly focusing on the mandatory job retirement regulation and its regulation of retirement ages. The empirical results show that the regulated retirement age is more important than the existence of mandatory retirement system in related to the workers' retirement decision.

The purpose of this study was to investigate food intake, dietary diversity and dietary pattern during the summer in middle aged and older adults living in Gugoksundam (Gurye, Goksung, Sunchang and Damyang counties), Jeonla Province located in southern part of Korea and known as one of the representative Korean longevity areas. Food intake and dietary diversity were assessed by using the data from 2 day-24 hour recall of 1,051 subjects (394 males and 711 females) aged 45 years and older (45-93 years in male, 45-105 years in female). The average ages of males and females were 70.7 years and 71.1 years, respectively. Average total daily food intake was significantly decreased with aging in both genders, and the average animal food intake ratio to total food intake was ranged 10~14% in 3 different age groups, 45~64 years, 65~74 years and 75 years and older. The contribution of each food group, in weight, to total food intake showed the descending order of grains, fruits, vegetables and alcohols in males, and grains, fruits, potatoes and meats in females. On daily intake amount of each food item, rice, watermelon, soju, kimchi, and potato were ranked on top 5 in descending order in males, and rice, watermelon, potato, kimchi and ylmukimchi in females. On intake frequency, rice, kimchi, onion, green pepper and potato were ranked on top 5 in descending order in both genders. Dietary variety score (DVS) and dietary diversity score (DDS) for the assessment of dietary diversity and balance were significantly decreased with aging in both genders. In food group intake pattern (DMGFV), 01101 type without consumption of dairy and fruits was the most prevalent, and only 3.6% of male and 3.9% of female subjects showed 11111 type, consumed all the 5 food groups a day. Dietary pattern of subjects was analyzed by cluster analysis with 18 food groups intake. Overall dietary pattern was classified into two clusters, one was more desirable and the other was less desirable. The percentage of subjects with more desirable dietary pattern was about 15% in male and 32% in female. In conclusion, most of our subjects living in Gugoksundam area were taking very simple diet with low amount of dairy products and fruits. These results indicate that nutrition intervention and education for older people living in rural areas should be focused on various food intake including dairy products and fruits.
