The purpose of this study was to examine and compare factors affecting the subjective life expectancy among the elderly, and to suggest health practice and social welfare service implications for later life. A total of 4,483 seniors from the 6th wave(2016) of the Korean Longitudinal Study on Aging (KLoSA) were used for analysis. The subjects were divided into three age groups: the young-old (n=2,106, 65~74 years), middle-old (n=1,803, 75~84 years), and oldest-old (n=574, 85 years and older). Control variables were sociodemographic factors and health status factors. Independent variables were health promotion behavior, cognition of public care, participating social activity, economic activity, and receiving basic pension. The data were analyzed using hierarchical multiple regression. The main results were as follows. Health promotion behavior was associated with the young-old. Social activities and economic activity were associated with the young-old and middle-old. Receiving basic pension had a significant impact on all age groups. In the middle-old, significant results were focused on socio-demographic and health status factors compared to other groups. The results of this study will provide basic data for the elderly policy and welfare service and will help to find and improve the important factors for the life of the elderly.

Due to the aging of a building, 38.8% (about 2.82 million buildings) of the total buildings are old for more than 30 years after completion and are located in a blind spot for an inspection, except for buildings subject to regular legal inspection (about 3%). Such existing buildings require users to self-inspect themselves and make efforts to take preemptive risks. The scope of this study was defined as the general public's visual self-inspection of buildings and was limited to structural members that affect the structural stability of old buildings. This study categorized possible damage to reinforced concrete to check the structural safety of buildings and proposed a checklist to prevent the damage. A damage assessment methodology was presented during the inspection, and a self-inspection scenario was tested through a chatbot connection. It is believed that it can increase the accessibility and convenience of non-experts and induce equalized results when performing inspections, according to the chatbot guide.

The proportion of elderly people over 50 years old in the total population of Korea increased from 29.2% in 2010 to 34.8% in 2015. As a result, the proportion of construction workers over 50 years old compared to the total construction workers increased from 20.1% in 2010 to 27.0% in 2015. In this aging society, the construction industry has faithfully carried out the business objectives and budget execution of measures to prevent disasters against elderly workers, but there was a limit to the fundamental prevention of disasters. Because the countermeasures for the prevention of construction disaster are considered on all ages rather than elderly workers. This study investigates the safety and health status of elderly workers at construction sites and suggests the plans to reduce disaster. In particular, to reduce disasters of rapidly growing elderly workers, the authors reviewed the related literature and safety regulations, statistics on the causes of industrial accidents, statistics on the status of industrial accidents, and applied to 3,549 workers who participated directly in the construction activities. The authors surveyed the actual situation of safety and health, presented the comprehensive disaster reduction measures by analyzing the current status and problems of disaster prevention projects. If the countermeasures proposed in this paper can be reflected in the actual policy, it is expected that the countermeasures will be possible to reduce the disaster of the elderly workers at the construction site, which is gradually increasing.
1. Objectives Purpose of this study is to prove anti-aging and anti-oxidative effects of Gongjinhugwon-dan decoction. 2. Methods The SD rats used in this experiment were 6, 18, and 36 weeks old. Each age group was again divided into three groups. These nine groups consisted of 8 rats each. One group was given no treatment, another group was dosed $200{\mu}l$ of normal saline daily, and the last group was dosed $200{\mu}l$ of 1 % Gongjinhugwon-dan and saline mixture. At the conclusion of the experiment, the age groups were relabelled accordingly (10 weeks, 22 weeks, and 40 weeks). After 4 weeks, change of weight and liver markers were measured. Serum LDL cholesterol, total bilirubin, albumin, glucose, GOT and GPT levels were observed in order to check the hematological modification. Also, each organ tissue was biopsied in order to measure the SOD activity and the glutathione content change. 3. Results & Conclusions Aging did not cause any significant change in GOT and LDH, but GPT and albumin levels showed increase after GHD intake. Serum GPT was lower in the experimental group. Serum total bilirubin of the 40 w GHD group was significantly increased. The populations of dendritic cells in the spleens of the GHD groups were significantly increased. The levels of GSH in the liver of the 40 w GHD group and in the kidney of 22w-GSD were significantly increased in comparison with those of the normal groups. The degenerative change of brain tissue was decreased in the 40 w GHD group compared with those of the 40w normal group and the 40 w saline group. These results suggest that anti-oxidative GSH concentration of liver and kidney in rats treated with GHD showed significant increase in the 40 w GHD group. GHD was effective on increasing anti-oxidative substance in liver and dendritic cells in spleen, thus helping immune system and preventing cell mutation and degenerative change of brain tissues. Further studies and clinical investigation with GHD is needed.
Qualitative properties- polyphenol compounds(total phenolics, anthocyanin, flavonoids, tannins), color parameters and antioxidant activities- of wild grape wine having different aging periods were studied. The contents of total phenolics and anthocyanin decreased significantly in accordance with aging terms(p<0.05). The total phenolics and anthocyanin of the oldest wine(WG3) represented only 43% and 45% of it's related compound in the wine aged for one year(WG1), respectively. The contents and the degree of polymerization of tannins, including condensed tannins, also decreased but not showed statistically significant. However, The contents of flavonoids of the 2 year old wine(WG2) decreased significantly related to that of WG1, remaining, then, almost constant at that levels during aging. The L* values, b(yellow) values and the hue (hab) values were increased in long aged wines(WG2, WG3), while the intensity of color(CI) and, the a(red) parameter value decreased. The antiradical activity of wild grape wines was shown to be high(87 EDA%) in WG1. The corresponding coefficient of tannin concentrations with antiradical activity($r^2$=0.9189) suggests that the tannin content may be strongly related to the antioxidant properties of wild grape wines.
The current study aimed to examine the gender differences in trajectories of nine successful aging indicators (chronic disease, depression, activities of daily living, instrumental activities of daily living, mini mental state examination, social activity, personal contact, health satisfaction, and general life satisfaction) with age, controlling the effect of education. The data were from the Korean Longitudinal Study of Aging, which had been conducted biennially from 2006 to 2016. The sample included 822 men and 1,236 women who responded to all of the panel surveys and were 65 years old or above in 2006. Multilevel modeling analyses showed that older men had fewer chronic diseases; lower levels of depression; higher levels of activities of daily living, cognitive function, and social activity; and better perceived health satisfaction and general life satisfaction at age 65 years compared to women. However, both men and women showed increase in the number of chronic diseases and depression level, and decrease in physical, cognitive, and social functions with age. In addition, perceived health and life satisfaction also decreased after the age of 65. The trajectories of most of the indicators were non-linear, and markedly increased or decreased around mid-70s. Study limitations and implications were further discussed.

Driving behaviors are reported to be vulnerable to safe driving in unexpected situations or driving in the city due to deterioration of physical and cognitive functions in elderly drivers. The purpose of this study was to investigate the difference in driving behaviors according to age of self-drivers and to identify changes in physical function related to driving caused by normal aging. The subjects of the study included 75 healthy adults (21 persons aged 20-39 years, 40 persons 40-64 years, 14 persons 65 years old) who were self-driving and possessed a driver's license. Data included sex, dominant hand, medication, exercise, age, and driving time obtained by a self-reported questionnaire. In addition, this study measured steering, acceleration and braking using a Driver Test Station. Results of the study showed there was no significant difference in power test according to age group, but the total time of the timer test and the emergency brake test significantly differed according to age. The timer test and emergency brake test were completed fastest in young adults between 20 and 39 years old and completed slowest in elderly people 65 years old or over. Based on our study results, it is suggested that normal aging affects the perceptual-cognitive processes associated with driving behaviors.
Purpose. To analysis the refractive error in 7-9 year-old Korea children. Methods. From July 2013 to June 2014, two hundred eighty two subjects were performed in refraction test using the Auto-Refractometry. Results. The refractive error by spherical equivalent among all subjects was myopia 47.58%, emmetropia 42.35%, astigmatism 32.33%, and hyperopia 8.76%. Myopia was more common in female than males although the difference was not statically significant. The axis of astigmatism was with the rule in 65%, against the rule in 31.5%, and oblique in 3.5% There was a statistical significance between 7 year and 9 year of male in the spherical equivalent power(p=0.010). Also there was a statistical significance between 7 years and 9 years of female in the spherical equivalent power(p=0.036). However, there was not a statistical significance between male and female in spherical equivalent power(p>0.5). Conclusions. In this study, myopia was the most common refractive error. On the other hand, The prevalence of the axis of astigmatism was the with- the- rule. The spherical equivalent of refractive error was similar results between male and female. However The refractive error was different style with aging. these data suggested that the analysis of the refractive error at young children can provide the information of useful diagnosis for the correction of visual acuity.
The purpose of the present study was to investigate the relationship between nutrient status, and bone mineral state which influenced by aging process. The subjects were 196 people over 65 years old(male 72, female124). The present dietary intake was estimated by the 24-hr, recall method, and individual dietary history concerning consumption of meat, fish and dairy products was obtained by questionaires. The syndrome of senility including seniliy was evaluated according to "Cornell Medical Index". The five subjects who showed 'Good' grade in bone senility, and five subjects who showed 'Risk' and 'Danger' grade were selected and their spine and femur bone density was measured by "Dual Photon Absorptiometry". The bone density measurement showed that the subjects with 'Good' grade in bone senility had bone density above that of normal person, and their nutrient status were satisfactory, whereas the subjects with 'Risk' and 'Danger' grade in bone senility had severe osteoporotic pattern, and their nutrient status were very poor. The food consumption score showed that the subject with higher intake of meat rather than milk had good grade in bone senility (p<0.05). Therefore, past meats consumption can be considered to be a significant factor in the present bone status. The nutrient intakes appeared to be significant factors in bone status in male, whereas there was little effect of nutrients intakes in female. Therefore, the risk of osteoporosis can increase as syndrome of bone senility and nutrient intakes were worse, and its is possible to evaluate bone status and predict osteoporosis simply from informations concerning syndrome of bone senility and nutrient intakes in old population over 65.
