This study was conducted on 1,174 retirees in their 50s and 60s nationwide using the 7th data of the National Pension Service's National Elderly Security Panel Survey. We were able to confirm the following results through the SPSS WIN 18.0 program.. First, men showed a higher level of education than women. From these results, it is expected that men will be better prepared for retirement. Second, men had spouses and two or more household members than women. According to previous studies showing that men are better prepared for retirement if they have a spouse, it is expected that men are better prepared for retirement. Second, 38% of men and 62% of women were voluntary retirees. Third, both men and women responded that their own and spouses should play the main role in preparing for retirement. Fourth, both men and women had very low rates of preparation for old age, economic independence, and public and private pensions. Among them, women were lower than men. Fifth, economic problem solving, health, and medical care were the priority as parts to be done for retirement in oneself and society. Based on these results, the directions for preparing retirees for retirement are as follows. First, education on wage peak system, retirement age extension and financial management for involuntary retirees is required, and guidance and management methods on health care and disease should be provided to address needs for health and health care. Women had more voluntary retirees than men, and they need to know why. Second, when both men and women are very poor at preparing for retirement, there should be job creation measures to ensure that they and their spouses are fully prepared for retirement.
Objectives: In most countries around the world, sex work is an illegal activity. Female sex workers (FSWs) in Iran hide their identities, and they are known to be a hard-to-reach population. Despite free access to HIV testing, fewer than half of FSWs receive HIV testing. The purpose of this study was to characterize the reasons for which FSWs do not seek testing at drop-in centers (DICs) and voluntary counseling and testing (VCT) centers in Iran. Methods: A qualitative study was conducted in 2016. The participants were 24 FSWs who received services at VCT centers and DICs for vulnerable females in the north of Iran and 9 males who were the clients of FSWs. In this study, we made use of purposive sampling and carried out a thematic analysis. Results: We found 4 major and 6 minor themes. The major themes were: fear of being infected (with HIV), stigma, indifference, and knowledge. Conclusions: Despite the significant efforts made by the government of Iran to establish and expand DICs for vulnerable females, the number of FSWs receiving services at these centers has not been very considerable. Consequently, by introducing and implementing training programs for peer groups, it may be possible to take steps toward establishing strategic programs for the control and prevention of HIV/AIDS.

Objectives: Thirdhand smoke (THS) refers to residual tobacco smoke pollutants that remain after cigarette smoking. The purpose of this study was to determine predictors of the belief among adults in Korea that THS is harmful to children. Methods: A population-based sample of 3,000 adults (${\geq}19$ years) among a web-based panel in Korea was obtained in November 2016. The respondents filled out questionnaires, including THS beliefs, smoking status, presence of voluntary smoke-free rules at home, and support for the implementation of smoke-free regulations at home. THS beliefs were assessed with a statement that staying in a room today where people smoked yesterday can harm the health of children. Results: Overall, 92.2 % of adults believed that THS exposure could harm the health of children. Respondents who were nonsmokers, believed that SHS exposure were associated with pneumonia of children, lived in home with complete smoke-free rule at home, and supported the implementation of smoke-free regulation at home were more likely to believe that THS could harm for health of children. Conclusions: The majority of Korean adults believed that THS exposure could harm the health of children. Predictors identified in the study can be useful to address the risk of THS beliefs and promote implementation of tobacco control policies.
This study examined the effects of hold-relax with agonist contraction (HR-AC) on the symptoms of delayed onset muscle soreness (DOMS) induced by intensive eccentric exercise of the non-dominant biceps brachii. Ten men (mean age=26.7 yrs, mean height=172.1 cm, mean weight=66.2 kg) and ten women (mean age=27.4 yrs, mean height=165.9 cm, mean weight=60.7 kg) who had not participated in a regular exercise program for the upper extremities in the previous six months were randomly assigned to one of two experimental groups: the HR-AC group, or the control group. We measured joint range of motion (ROM), maximal voluntary isometric contraction (MVIC), and muscle soreness before eccentric exercise, and 24, 48, and 72 hours after eccentric exercise. The subjects in the HR-AC group received the HR-AC technique in the non-dominant biceps brachii. The HR-AC technique was applied 24 and 48 hours after eccentric exercise. There was no significant difference between the HR-AC and the control group. However, the HR-AC group, compared to the control group, had a significant difference between the time points of the various parameters. Increased ROM (p<.05), decreased muscle soreness (p<.05), and reduced MVIC (p<.05) were found in the HR-AC group after 72 hours. Decreased ROM (p<.05) and MVIC (p<.05), and increased muscle soreness (p<.05) were observed in the control group. These findings suggest that the HR-AC technique effectively reduces muscle soreness and increases ROM 72 hours after eccentric exercise.
Purpose: This study was conducted to examine the effects of osteoporosis prevention education on Korean breast cancer patients' knowledge and health promoting behavior. Methods: The participants in this study included breast cancer patients who were registered at a self-help group organized by the Breast Cancer Center of a university hospital in Seoul, Korea. The intervention group received 60 minutes' didactic instruction followed by 30 minutes' interactive session, and reinforcement education with leaflets was given three weeks after the group intervention. In order to measure the effects of the intervention, this study used valid and reliable scales on the knowledge of osteoporosis and health promoting behavior for preventing osteoporosis. A post-test was conducted 12 weeks after the intervention. Results: The results showed significant improvement in three of the five factors of osteoporosis knowledge including bone physiology, the characteristics of osteoporosis, and preventive behaviors in the intervention group. Overall health promoting behavior for preventing osteoporosis had significantly increased in the intervention group compared to the control group. Conclusion: Osteoporosis preventive education improved breast cancer patients' knowledge of osteoporosis and health promoting behavior for preventing osteoporosis by inducing their voluntary participation in self-care activities.
Objective and Background: The objective of this study was to evaluate the association of individual characteristics, work-related factors, lifestyle factors, and health problems with work ability among aging workers in Korea. Method: In this cross-sectional survey, the study population consisted of 1,594 workers who had participated in a voluntary health promotion center and private workplace. Participants completed the work ability index. Results: The mean WAI score was 37.4, while the mean age of the sample was 43.25. In the age group over 50 showed 36.26. The majority of participants rated their work ability as 'good' to 'excellent', one-third moderate and about 7.5% poor. Work ability decreased significantly with age among the men. The younger group had higher scores on the work ability index than the age group over 50, except for mental resources. By work characteristics, work ability was analyzed to be the lowest in the case of work handling heavy stuff. Lastly, as a result of health factors analysis, the good management and retention of current health status can be the measure helpful to the improvement of work ability. Conclusion and Application: According to the results, it can be a basic principle to devise and enforce preventive measures on the factors for which improvement or action is possible, together with workplace-level systematic approach, in order to improve work ability. For such measures to be realized, it is necessary to check trends in change for several years.
Purpose: This concept analysis was conducted to clarify 'parents' treatment adherence for an epileptic child or adolescent'. Methods: The analysis used a hybrid model comprising three phases: theoretical phase, fieldwork phase, and integration phase. In the theoretical phase, fifty studies were reviewed. Interviews with four parents of epileptic children or adolescents were conducted during the fieldwork phase. In the integration phase, the results derived from prior phases were synthesized and clarified. All phases were performed cyclically. Results: The concept, 'parents' treatment adherence for an epileptic child or adolescent' was defined as parents' voluntary and goal-directed behavior towards the epilepsy treatment for their children: a collaborative decision-making process with health-care providers, establishing a support system, adaptability to the treatment plans, and appraisals of the child's health condition. Conclusion: This achievement is thought to contribute to improving the accuracy and validity of the concept measurement. It has implications for additional research on how the concept 'treatment adherence' differs in diverse health problems and other population groups than parents of children and adolescents with epilepsy.

Purpose : We studied the correlation between reference voluntary contraction (% RVC) of vastus lateralis (VL) and vastus medialis (VM), Berg balance scale (BBS), and timed-up & go (TUG) test. Methods : We recruited 30 stroke patients from a rehabilitation center at a hospital.? All subjects could walk with or without an assisting device. Subjects were evaluated with % RVC of VL and VM, BBS, and TUG. The data were analyzed using a Pearson correlation coefficient. Results : The % RVC of VL and VM and BBS (p<0.01) showed a significant positive correlation. TUG negatively correlated with % RVC of VL and VM and BBS (p<0.01). Conclusion : Lower extremity muscle activity increases balance and walking ability. We recommend the implementation of lower extremity strength exercises in the rehabilitation of stroke patient.
Background: Firefighters are required to use self-contained breathing apparatus (SCBA), which impairs ventilatory mechanics. We hypothesized that firefighters have elevated arterial $CO_2$ when using SCBA. Methods: Firefighters and controls performed a maximal exercise test on a cycle ergometer and two graded exercise tests (GXTs) at 25%, 50%, and 70% of their maximal aerobic power, once with a SCBA facemask and once with protective clothing and full SCBA. Results: Respiratory rate increased more in controls than firefighters. Heart rate increased as a function of oxygen consumption ($V_{O_2}$) more in controls than firefighters. End-tidal $CO_2$ ($ETCO_2$) during the GXTs was not affected by work rate in either group for either condition but was higher in firefighters at all work rates in both GXTs. SCBA increased $ETCO_2$ in controls but not firefighters. Conclusions: The present study showed that when compared to controls, firefighters' hypoventilate during a maximal test and GXT. The hypoventilation resulted in increased $ETCO_2$, and presumably increased arterial $CO_2$, during exertion. It is proposed that firefighters have altered $CO_2$ sensitivity due to voluntary hypoventilation during training and work. Confirmation of low $CO_2$ sensitivity and the consequence of this on performance and long-term health remain to be determined.
The social activities of the elderly have been increasing as our society progresses toward an aging society. As their activities are increased, the occurrence of falls that could lead to fractures are increased. Falls are serious health hazards to the elderly and we need more thorough understanding of falls including the progress of falls and the impact area in various fall directions. Many of the traditional methods of falls research dealt with voluntary falls by younger subject since older subject can easily get fracture from voluntary falls. So, it has been difficult to get exact data about falls of the elderly. Here, we tried to capture the characteristics of the movements of major joints using three dimensional motion capture system during falls experiments using a moving mattress that can safely induce unexpected falls. Healthy younger subjects participated in the actual falls experiment and the moving mattress was actuated by a pneumatic system. The kinematic parameters such as velocities of major segments were imported to a computer simulation environment and falls to hard surfaces were simulated in a computational environment using a realistic human model of aged persons. The simulation was able to give approximations to contact forces which can occur during actual falls. And we designed impact absorption system to reduce the impact during falls. We can adapt this system to fracture prevention system that we are going to study.
