The purpose of this study was to investigate whether there is a relationship between pulmonary function, serum lipid and pulse pressure, which is a risk factor of cardiovascular disease, in subjects with 109 office workers(51 males and 58 females) be at Seoul, Korea. The mean age of the subjects was $43.44{\pm}7.23$ years old (male $43.44{\pm}7.27$, fenale $49.1{\pm}11.5$). The subjects' height, weight, BMI, systolic and diastolic blood pressures were measured and there was statistical difference between men and women.The mean pulse pressure of the subjects was $47.82{\pm}9.02mmHg$, and the mean of FVC was $84.26{\pm}9.91%$. There was no difference between men and women in both. There was a positive correlation between pulse pressure and systolic blood pressure in males (p<0.01) and females (p<0.01), and FVC and HDL in males were positively correlated (p<0.05). Pulse pressure and %FVC were negatively correlated (r =-0.267, P<0.01). Pulse pressure and %FVC were negatively correlated (r =-0.267, P<0.01). Regression analysis showed that PP was the independent affected %FVC. Therefore, pulse pressure and %FVC may be useful as a predictor of cardiovascular disease in middle-aged subjects with normal, suggest a long-term convergence follow-up is warranted to elucidate the incidence of cardiovascular disease.

This study was performed to test the socioemotional selectivity theory (SST) with Korean adults. According to SST, perceiving their life as limited, people are motivated to enhance their mood by regulating their mood in such a way to maximize the positive emotions and weaken the negative ones. Being founded on the dialectical constructs which assume the positive and negative sides of emotional experience coexist, Korean adults were supposed to be less motivated to maximize positive emotions and weaken negative emotions. Thus the elderly koreans might regulate emotions not in the direction of maximizing the positive emotions and weakening the negative ones, but in the direction of not being highly aroused. 166 youth, middle-aged, and elderly were asked to rate the frequencies of 31 positive and negative emotions they had experienced during the last month. In addition, they were asked to judge whether they weaken / adapt / maximize their emotions after experiencing positive and negative events. The elderly experienced less positive emotions as well as negative emotions than youth. Youth experienced emotions of high arousal more often than those of low arousal, but the elderly experienced emotions of high arousal less often. The responses of weakening their negative emotions and their positive emotions were largest in the elderly group. On the other hand, the response of maximizing their positive emotions were largest in the youth group. These results show that the elderly maintains emotional stability by weakening both positive and negative emotions of high arousal.

Recently, the nation has been suffering from a variety of problems, such as the rapid aging of the population and the weakening of the family's role due to rapid industrialization, such as the problem of supporting the elderly or the decline in the quality of supporting them. Among them, the issue of supporting the sentiment of the elderly is a major issue in terms of the quality of the stimulus. The best solution would be to resolve this issue of emotional support through various physical and human support. However, due to various limitations, access to efficient utilization of resources is being sought, among which support efforts through the convergence of digital technologies need to be noted. In this study, we took note of the problems of aging population shortage due to aging phenomenon and the problems of the emotional side of the problem of declining quality of the service, and analyzed the types of digital technology applied to support the emotional side through the convergence of digital technology. Among them, the Commission proposed emotional support through smart speakers, confirming the possibility of supporting the elderly through smart speakers. In addition, the Commission proposed guidelines for smart speaker communication systems to support the sentiment of older adults by conducting an in-depth interview with the In-Depth interview with the evaluation of the usability of smart speakers for older people. Based on the results of this study, it is expected that it will be the basic data for designing a communication system when developing smart speakers to support the emotions of the elderly.

This study explored how retirement satisfaction or dissatisfaction influences on retirees' life satisfaction, comparing to workers and the gender differences were examined. The study sample was 2,609 persons (1,886 workers, 723 retirees) aged 45 or older who participated in the 1-2 waves of the Korean Longitudinal Study of Ageing (KLoSA), and the retirees were classified into continuously dissatisfied retirees and satisfied retirees during wave 1 and 2. Using SPSS 21.0, the multiple regression models were examined, and in order to clarify the gender difference, the multi-group analysis and the wald-test were conducted to test the difference of the regression coefficients according to gender using Mplus 7.3. According to the results, the life satisfaction of dissatisfied retirees was lower than that of the employed, but when satisfied with retirement, the life satisfaction was higher than that of the employed. In addition, the dissatisfied retirees in both gender were less satisfied with life than the employed, and this effect was greater in female group. However, the life satisfaction of female satisfied with retirement was higher than that of the employed, whereas the evidence of the male influence was not found to be significant. Based on the results of this study, discussion about heterogeneity of retirees and gender differences in life span were presented.

The purpose of this study is to investigate what kind of research fields are preferred by the researcher of the Korean Physical Education Society using the Mecab-ko morpheme analysis and whether there are differences in the interests of researchers between the humanities and social sciences and natural sciences. A total of the data collected for this study are 5,014 papers published online from March 2002 to March 2017 in the Korean Journal of Physical Education was collected. In this study, we used Mecab-ko morpheme analyzer to extract the keyword from the collected documents. As a result, the study found that the number of papers published in KAHPERD appeared to be decreasing. It was also that the main concern of researchers in KAHPERD toward was leisure, live sports and health were relatively higher than the improvement of performance. The research subjects that were interested in the research were women, middle-aged and elderly. The study found that researchers in the humanities and social sciences have shown interest in both traditional research and social interests, while researchers in the natural sciences have shown an interest in a deeper study of traditional research. In conclusion, in order to realize the revitalization of sports convergence research, it is necessary to establish standards for the field of study which should focus on the depth and breadth of research.

The transition into a digital society has been accelerated in many aspects of our everyday social activities, and thereby, the unmanned order and payment system via kiosk has already has been seen commonly throughout the social community. Yet, the majority of the mid-to-elderly population have been experiencing difficulties utilizing this newly emerged unmanned system, resulting in the emergence of digital alienation among those age groups. In regard to this phenomenon, this study is intended to explore ways to improve the digital divide concerning the issues related to the unmanned order payment kiosks. In this process, the study involved close examination of various research perspectives on improving the digital divide and proceeded with the focus on both empirical and literature research on providing education on kiosk utilization. In addition, the study identified the limitations to the current kiosk education and proposed improved kiosk-education software UX that may help curtail the limitations. Through this, one was able to identify areas in which the efficacy of the education applied in kiosk usage and derived new measures that could improve the system. One anticipates having the results of this study put to use as research materials on educational service development to expand the opportunities of kiosk education for those mid-to-elderly age groups who experience a day-to-day digital alienation.

This study identified effect size of cognition improvement programs developed for normal elderly in Korea. By searching four databases, 9,624 studies published from 2000 to 2016 were identified. Finally, 14 studies which satisfied the inclusion criteria were selected for meta-analysis. Quality assessment of included studies was conducted using controlled trial checklist of Scottish Intercollegiate Guidelines Network. R version 3.3.2 (2016-10-31) with "meta" and "metafor" package was used to calculate effect sizes, identify the reasons of heterogeneity, and check publication bias. Total effect size of cognition improvement program was middle (SMD=0.759, p<.001, $I^2=34%$). For heterogeneity, moderator analysis was executed and combined program with exercise had the largest effect size (SMD=1.231, p<.001, $I^2=40.8%$). Publication bias was exist by funnel plot and Egger 's regression test, but trim and fill analysis showed that there was no serious error to reverse study results. Therefore, Combined program with exercise for the normal elderly was expected to improve the cognitive function of the normal elderly.

This article is an exploratory study on the recent growth of short-hours part-time work in Korea. The short-hours part-time work has been rapidly growing among low-educated women over sixty, particularly among bereaved or divorced women, contrary to the expectation of the government that encouraged the part-time work by means of work-family balance for working mothers or middle-aged women who experienced career interruption. The short-hours part-time jobs are concentrated in social service industry, mostly elderly care service jobs, and their working conditions are extremely poor, mostly low-wage jobs with no social insurances except for health insurance. In this study, we discuss why the short-hours part-time work has grown so fast in Korea since the mid 2000s. Using various governmental statistics, we examine the effects of the labor demand and supply situations during the time period, the legal context that is related with the exempt clause of the labor law, and the institutional context related with the government's public job creation projects for the elderly. We suggest some public policies needed to slow down the growth of the short-hours part-time jobs and to elevate their working conditions.

This study examines whether formal home care has led to a reduction in family member's allocation of time to care of elderly and changing the allocation of other time: informal care, market work, leisure, etc. Long-term care for the elderly is not the entire burden of elderly families anymore due to the increasing of the formal home care service for elderly since mid-2000's. This study uses triple difference(DDD) methods for evaluating policy reforms when reforms are equally and nation-wide accessible and analyzes data from the 2004 and 2009 Time Use Survey Data of the National Statistical Office in Korea. The treatment group is composed of the families of the elderly who need care and low- and middle- income family. Controlling for demographic characters, the three-way interaction term has statically significant and negative impact on care time of family members in treatment group statistically significant. The results reveal that the policy changes in elderly home care service affect time allocation of family members with old adults, which decreases caregiving time in a daily life. This result becomes apparent when we limit the case of women. But the level of reduction is not enough to change other kinds of time-informal care, market work, leisure, etc. The results indicate that formal home care for the elderly can reduce the burden of caregiving in families, but only minimally.
