The population of Korea is ageing as the number of elderly people increases due to improvements in health care and diet. Accordingly, it is expected that interest in how to live actively during the years after retirement and how to communicate effectively will increase the demand for voice improvement methods and technology. However, the criteria to evaluate the voice strength and characteristics of the elderly are lacking. In this study, we analyzed the acoustic characteristics of elderly women living in the community according to residential status and mental health status (e.g. depressive mood). Accordingly, we selected women (n=63) above the age of 65 age who were living in the Seoul metropolitan area and Daegu Gyeongbuk. The selected subjects were divided into two groups: a normal speaker group (n=40) and a speaker group comprised of those suffering from depressive mood (n=23). This study analyzed the voice characteristics of subjects based on collected data through the sustained phonation of the vowel /a/. It was shown that there were differences among MPT, F0, Jitter, Shimmer and NHR depending on location of residence but no difference with regard to depressive mood. Therefore, we must consider location of residence in elderly as the key factor in demonstrating the voice norms of seniors.

This study examined whether structural (coresidence, proximity) and associational (frequency of face-to-face contact, frequency of contact via phone, email or letter) solidarity between adult children and older parents may influence older parents' cognitive functioning. Adult children may help delay older parents' cognitive decline by promoting healthier lifestyle, engaging parents in complex everyday problem solving, and providing emotional support. The data consisted of men and women 65+ at Wave 1 who had at least one child 20+ and participated in at least two waves of the Korean Longitudinal Study of Ageing (KLoSA, N=3,961). Cognitive functioning was measured with the Korean version of the Mini Mental State Examination. Fixed effects models were estimated using the xtreg procedure in STATA. Findings suggest that increases in proximity with at least one adult child may lead to enhanced cognitive functioning among older parents. Neither transitioning to coresidence with at least one adult child nor increases in frequency of contact with at least one non-resident adult child was associated with changes in older parents' cognitive functioning. With older parents' increasing preference for living close by, but not necessarily living with adult children, greater proximity may provide more opportunities for reciprocal support exchanges between the two generations, leading to better cognitive functioning of older parents.

Guided by the exchange model, altruistic model, intergenerational solidarity theory, and cultural contexts, this study explored the determinants of financial intergenerational transfers between older parents and adult children in South Korea. We examined 18,820 parent-child dyads by using random-effects models on the first wave of the Korean Longitudinal Study of Ageing (KLoSA) data. Findings showed that downward financial intergenerational transfers were consistent with the self-interest exchange model but upward transfers did not support microeconomic theories. Family solidarity theory was generally supported by downward transfers but geographical proximity was not positively associated with upward transfers. Lastly, cultural contextual variables such as marital status, birth order, and sex of a child were found to be significant. Parents tended to both provide and receive more financial support from unmarried children than from married children. Within the same marital status, the hierarchy existed in order of the first-born son, the second or later sons, and daughters when it came to downward financial transfers. Regarding upward financial transfers, the preference in order was more complicated. The findings of this study help in understanding the intergenerational financial transfers in the Korean context.

The authors, to collect some necessary data to promote correcting the toothbrushing method, the most basic home dental care, and to arrest the attention to the dentifrices in Korea, observed and evaluated the cervical abrasion experience rate in 8,000 Korean male and female adults from 19 to 52 years in the age, which had been extracted by the stratified random sampling method. The obtained results were as follows; 1. Cervical abrasion experience rate was 18.6% in Korean adults. 2. Cervical abrasion experience rate in male adults was higher than that in female adults. 3. Cervical abrasion experience rate was gradually increased by ageing. 4. It seemed the cervical abrasion experience rates in the adults in Honam and Youngnam district to be higher than those in the other districts. 5. In Korean adults, the further detail inveatigations into the cervical abrasion were required.

The purpose of this study was to explain the influence of depression on the life satisfaction of the elderly with hypertension. Also, we were focusing whether there is a mediating effect of subjective health status between depression and life satisfaction of the elderly with hypertension. 2,198 persons with hypertension over 65 years of age were selected from the data of KLoSA(Korean Longitudinal Study of Ageing), administered by The Korea Employment Information Service in 2014. Life satisfaction was measured by 10-Likert. The depression measured by CES-D10. The mediating variable is subjective health status measured by 5-Likert. As the method of analysis, the multiple regressions were used with SPSS 19.0. The result of the study shows that depression has a negative influence on life satisfaction and a negative influence on subjective health status. It was also verified that the subjective health status variable has a mediating effect between depression and life satisfaction. These results present the importance of psychological approach for the health promotion experts intervening with the elderly with hypertension.

Purpose: This study aimed to identify the health behaviors of working elderly Koreans aged 65 over and examined the socio-demographic and disease-related factors by health behaviors. Methods: This study used data obtained from the 2nd basic survey of the 2008 Korean Longitudinal Study of Ageing. We selected 381 working elderly having one or more of the diseases hypertension, diabetes, heart disease or cerebrovascular disease. Results: 78.9% out of the subjects have hypertension, 31.2% have diabetes, 12.3% have heart disease, and 6.3% have cerebrovascular disease. Compared to the health behaviors of the general elderly, the rate of the practice of regular exercise among the subjects was lower, but the smoking and drinking rate were higher. The significant variables associated with health behavior practice rates were gender, type of work, subjective health status and chronic diseases. Conclusion: The type of work of the elderly with chronic diseases was significantly associated with health behaviors. Consequently, this study found that continuous care programs for the working elderly with chronic diseases should be developed and provided as an occupational health service when the jobs are offered to them.

According to the Korea National Statistical Office data in 2010, the population over ages of 65 years would possess to 11.3% whole population of Korea in 2011 denoting Korea is already in the aging society. Old age is associated with inevitable time-dependent losses in physical capabilities. However the maintenance of physical capabilities is essential for continuing independence in old age. The work ability index(WAI) was constructed to reveal how well a worker is able to perform his work. This study focused on the discovery of an industrial and age-related influences on the work ability and job stress of workers in the shipbuilding, house managing, apartment construction industry. For this, the study conducted a job stress test using the Korean Occupational Stress Questionnaire Short Form, and employee performance evaluations using the Work Ability Index (WAI) of the Finnish Institute of Occupational Health (FIOH) on 3,228 workers in the shipbuilding, house managing and apartment construction industry. SPSS 12.0 K statistics program was used for statistics analysis and significance was verified with the Kruskal-Wallis test, a corporate body of nonparametric statistical analysis. As a result, employee performance had significant differences, depending on age, an industrial and years of service. The mean WAI score of the shipbuilding industry was lower than that of the other industry. Additionally, it was found that employee work ability decreased more as job stress increased.

Industrial cooling towers are often ageing infrastructure that is expensive to maintain and operate. A novel approach is introduced in which a heat pump circuit is incorporated to reduce the load upon the towers by extracting low-grade energy from the stream sent to the towers and repurposing in on-site processing operations. To demonstrate the concept, a model was constructed, which uses industrial data on cooling towers linked to a smelter's sulphuric acid plant, to allow direct economic and environmental impact comparison between different heat recovery and repurposing scenarios. The model's results showed that implementing a heat pump system would significantly decrease annual operating costs and achieve a payback period of 3 years. In addition, overall CO₂ emissions could be reduced by 42% (430,000 kg/year) and a 5% heat load reduction on the cooling towers achieved. The concept is significant as the outcomes introduce a new way for energy intensive industrial sectors, such as mineral processing, to reduce energy consumption and improve long-term sustainable performance.

Purpose : This study was assessed muscle activity and onset time in trunk and upper extremity on functional reaching. Methods : The participant was 18 female(young 10, old 8). As functional reaching, we collection data by using EMG(MP150) on transverse abdominis, external oblique, erector spinae, deltoid middle and serratus anterior. Results : 1) In functional reaching, transverse abdominis, external oblique, erector spinae and deltoid middle muscle activity was augmented on old female(p>.05). Serratus anterior was augmented on young female(p>.05). 2) In functional reaching, transverse abdominis and erector spinae muscle onset time is significantly faster old female than young female(p<.05). External oblique and serratus anterior muscle onset time is faster old female than young female(p>.05). 3) As increase of age muscle activity of external oblique was more increased that we found .511 a coefficient correlation and onset time more faster on transverse abdominis and erector spinae were each -.492 and -.554 coefficient correlation. Conclusion : The muscle activity and onset time was difference in functional reaching according to ageing and task context. It is necessary concentration and attention to old female than young female. Therefore, these results suggest that importance of anticipatory postural control and selective strategy of postural control.
