This study examined the effects of sling-complex exercise on depression, function, and quality of life in the elderly. As a study method, 40 elderly people aged 65 years or older among nursing homes in M Hospital located in D city were compared randomly with the Suspended Combined Exercise Program group (n=20) and control group (n=20). This was measured using the GDS for depression before and after the intervention for 60 minutes, two days a week for 12 weeks for the combined exercise program with a sling and the same program without a sling. In addition, the quality of life was measured using self-efficacy. For comparison within the group, a paired t-test was applied, and a two-sample t-test was used for the comparison. After the intervention, the experimental group showed a significantly greater change in all evaluations (GDS, FIM, and self-efficacy) compared to the control group (p<0.05). Moreover, there was no significant change in the general self-efficacy of the control group (p>0.05). Overall, the sling complex exercise program is effective in improving the quality of life of the elderly.

The Interest in disease prevention and rehabilitation is increasing depending on increase of patients with spinal. This is being developed using the spine stabilization device is being studied. So far studies have only evaluated the effect on trunk stabilization exercises but analysis of human movement patterns for active movement and passive movement did not. We assessed the muscle activity of trunk and leg muscle during passive and active tilt mode on eight tilt directions at tilt angle of $30^{\circ}$ using 3-D dynamic postural balance training system. We performed experimental study on the muscular activities of trunk muscle about rectus abdominis, external obliques, latissimus dorsi, erector spinae, and leg muscle about rectus femoris, Biceps femoris, Tibialis Anterior, gastrocnemius. As a result, muscle activation was different depending on the direction of movement and pattern. The results indicate that various patterns of spinal stabilization exercise system could be applied to an effective training of chronic low back pain patients.

This study examines the interplay between the reactions of YouTube users and North Korean propaganda. Interesting enough, the study has noticed changes in the strict media environment under young leader Kim. Messages delivered by the communist regime to the outside world appeared to resemble those of 'normal' countries. Although North Korean YouTube was led mainly by the account operator, visitors from different nations do comment on the channel, which suggests the possibility of building international communities for propaganda purposes. Overall, the study observed a sparsely connected social network among ordinary commenters. However, the operator did not exercise tight control over peer-to-peer communication but merely answered questions and tried to facilitate mass participation. In contrast to the many news clips, the documentary content on North Korea's YouTube channel did not explicitly advocate for North Korea's current political positions.

To solve the addition word problems provides young children the chance to learn about and exercise in problem solving. This paper focuses on two aspects to be considered in addition word problems: the homogeneity of objects and the variety of contexts. The homogeneity of objects involved in addition word problems has to be kept in the following reasons: concept of unit, effectiveness of information, prevention of inappropriate variety, inconsistency of mathematics with real world, continuity between elementary and secondary mathematics. And for the variety of contexts, the additive structure proposed by G. Vergnaud, can be considered: composition, transformation, relation of comparison, composition of two transformations, composition of two relations, transformation of a relation. According to this structure, some examples, which contain homogeneous objects, were extracted from the elementary school mathematics textbooks.

This study was undertaken to develop a bed-type cycling system of lower limbs for rehabilitation. This system consists of two modes of cycling: active and passive. Different velocity and loads are provided for improving the muscle function recovery and increasing the muscular strength. To analyze the muscle activity pattern, we measured muscular activity of lower limbs in the rectus femoris (RF), biceps femoris (BF), tibialis anterior (TA), medial gastrocnemius (MG), and soleus (SOL), while cycling in the supine position, and based on the pedaling direction. A total of 18 young and 23 elderly, healthy subjects participated in this study. Muscle activity of MG muscles was significantly different in the two age groups. This study could provide the reference data to develop cycling exercises for lower limbs during rehabilitation of the elderly patients.

The purpose of this study is to examine how Korean dance affects middle-aged women by acting as a cultural mediator. A qualitative approach was taken in order to best achieve the purpose of this study. The data used in this study were collected from Feb 10th to April 1st, 2016, using in-depth interviews. The results are as follows; firstly, on an emotional level, the middle-aged women participating in Korean dance as a cultural mediator, feel a sense of self-achievement and social belonging, as well as experiencing an improvement in their psychological stability by resolving their depression. Those who had lost their sense of autonomy and productivity were able to recover some of their self-esteem through this activity. Secondly, in terms of their activity, the Korean dance enabled the ladies to exercise their poorly used muscles by strengthening their gross and fine motor skills through the movements associated with the Korean traditional music. This allowed them to ease their chronic physical pain and it can be considered that their overall exercise function was increased by expanding their exercise radius. Third, in the cognitive area, it was possible for them to revive their happy memories by listening to the music which was loved by their preceding generations. This is because the melody of familiar Korean music provides them with the chance to remember their former days. Lastly, in the social area, the Korean dance allowed the middle-aged women to accept themselves through music and movement, as well as playing the role of a mediator which enabled them to overcome their isolation and the conflicts they face in their social relations. In addition, they achieved self-realization by reconnecting with the regional community through the Korean dance performances, which they learned as social community members.

This study examined the impact of late-life poverty on self-rated health, focusing on the mediating and moderating effects of health behaviors and social support. Despite the significant associations among poverty, health behaviors, and health outcomes, little studies have tested complex structural pathways among them. Thus, the purpose of this study is to identify multiple causal pathways between poverty and self-rated health, mediated and moderated by health behaviors and social support. To test the structural pathways, the structural equation modeling was utilized using the 2006 Korean Longitudinal Study of Aging data. The results of this study indicated that poverty had the direct negative impact not only on the health behaviors such as smoking and lack of regular exercise but also on the self-rated health. In addition, regular exercise significantly mediated the relationship between poverty and self-rated health. Finally, informal social support from family and friends buffered the negative impact of poverty on the self-rated health. Findings suggested that providing informal social support to the low income elderly is important in addition to the economic support. It is also necessary to develop programs for promoting healthy behaviors, especially regular exercise.

Objectives: This study was attempted to examine the relationship between hand grip strength and dyslipidemia. and it was analyze the effect of hand grip strength on dyslipidemia and discuss the problems that may occur. Methods: The study focused on 'the National Health and Nutrition Survey's 7th Year 1, 2, and 3 (2016-2018)' as their primary data. Among people who measured dyslipidemia and relative hand grip strength, 12,636 people were selected as the final study after excluding missing values. Frequency analysis, mean analysis, and regression analysis was used to determine dyslipidemia and hand grip strength indices according to the subjects' characteristics study and verify the research hypothesis. Results: Outcomes show that 4,542 (35.9%) of the subjects were dyslipidemia, and when the hand grip strength of the subjects increased by 1kg, Dyslipidemia decreased by 0.217 less. The result of subdivided and analyzed dependent variables presented that every time the hand grip strength increased by 1kg, the L-HDL -C decreased by 0.325 less, but it did not affect H-LDL-C and H-TG. Conclusion: In order to reduce dyslipidemia, it is essential to recognize the necessity of muscular exercise and fulfill it. Focus on health care, such as health conditions, health behavior, and make efforts to participate in health education. If so, it is expected to help reduce the economic burden, such as the treatment of dyslipidemia and improve the quality of life free from mechanical circulatory diseases.

Objectives : Hypertension (high blood pressure), one of the world's major chronic diseases, has a high mortality rate due to its high prevalence and complications, but its control rate is low. The proper management and control through appropriate exercise, diet management, and optimal drug choice can reduce the risk of death from hypertension. Although various antihypertensive drugs are used to treat hypertension, they also have numerous adverse effects. Alongside increased interest in the use of Traditional Herbal Formulas (THF) for hypertension treatment, the purpose of this study was to examine the vasodilative effects of 10 THF in the rat thoracic artery pre-contracted by potassiumchloride (KCl). Methods : THF were extracted with distilled water for 2 hours. The rat thoracic artery was suspended and contracted by KCl in the organ bath which contained 10 ml Krebs Henseleit (KH) buffer. THF extracts were added in a dose-dependent increase (10-1,000 ㎍/mL) to examine vasodilative effects. The vasodilative effects produced by THF were expressed as the percentage in response to KCl-induced contraction. Results : Among the 10 THF, Banhasasim-tang, Buhnsimgieum, Sagunja-tang, and Samul-tang showed vasodilative effects. And, Sipjeondaebo-tang, Ssanghwa-tang, Ojeok-san, Onkyung-tang, Yongdamsagan-tang, and Hyangsayukgunja-tang showed no significant vasodilative effects. Also, in co-administration with amlodipine, Banhasasim-tang showed higher vasodilative effects than amlodipine alone, and Buhnsimgieum showed greater vasodilative effects at low concentrations, but inhibited amlodipine's vasodilative effects at high concentrations. Conclusion : As a result of these studies, they will be expected to provide useful data to establish guidelines of combined administration of THF and western antihypertensive drugs for the treatment of hypertension.

The purpose of this study is to explore qualitatively what kind of coping strategy the Korean older adults use when they are depressed and why. Participants were users, older than 60, of an elderly welfare center in Seoul, and answers of 34 respondents who experienced depression were included in the analysis. The collected data were analyzed through content analysis. The results of the analysis showed that strategies to cope with depression used by participants were composed of 6 domains and 11 sub-domains: health behavior (medical approach / exercise and diet), family and social contact (social interaction / going out and going on a trip / communication with family), Religious activities (Religious activities), lifelong education (hobbies / educational activities), productive activities (labor), health risk behaviors (drinking and gambling / resignation). The depression coping strategies of the older adults and their characteristics are as follows. First, older adults used diverse problem-focused coping strategies to cope with depression. Second, older adults considered various coping strategies together and used them simultaneously. Third, the facility space for older adults functions as a shelter. Fourth, although there were cases where medical approach was used, the intention to reuse was very low. Through this study, the following suggestions were made to help older adults cope with depression more successfully. First, access to various coping strategies should be promoted. Second, more places where older adults can spend their time comfortably need to be provided. Third, resistance to mental health care should be resolved.
