The purpose of this study is to identify the link that affects depression, a negative mental health problem for permanent rented apartment tenants, and to provide policy and practical support for reducing depression at the community level. To this end, 1,920 households of permanent rental apartment residents in K Metropolitan City were used in the survey. The results are as follows. First, more than half of the subjects surveyed 51.1% were found to have depressive symptoms. Second, among the demographic variables, the gender, age, single-person households, and social security benefits have a positive effect on depression. On the other hand, age squared and participation in economic activities were identified as factors to reduce depression. Third, among the residential community variables, the consideration for neighbors and their willingness to participate in the community were identified as factors to reduce depression. Fourth, physical health difficulties and mental health difficulties among the health status variables were identified as the determinants of depression. Based on the results of the study, the methods for intervention and follow-up studies to reduce depression in permanent rental apartment residents were discussed.

Background: Korea shows rapid population aging and increase in healthcare service use and expenditure. Also, this would be accelerated because of the baby boomers who will be 65 years old and more in 2020. Chronic disease is another reason that increases the use of healthcare service and expenditure of the middle- and old-aged households. Catastrophic health expenditure (CHE) is the index which can indicate the households' burden of health spending. Despite the importance, there are few studies on CHE of middle- and old-aged households and especially no panel study yet. This is the reason that this study is carried out. Methods: This study used 3-year data from the Korea Welfare Panel Study conducted from 2009 to 2011. We defined CHE if a household's health expenditure is equal or greater than the threshold value if income remaining after subsistence needs has been met. We used 4 different threshold values which are 10%, 20%, 30%, and 40%. In order to look at the households which experienced CHE, we conducted panel logit analysis after correspondence analysis and conditional transition probability analysis. Results: This study showed three notable results. First, there has been a difference among age groups, which implies that the older people are, the more easily they can experience CHE. Second, the households with no private insurance are shown to have a higher CHE occurrence rate. Lastly, there has been a significant difference among the kinds of chronic diseases. The households which have cancer, cerebrovascular disease, and heart disease have a higher CHE occurrence rate. However, the households with diabetes have no significant effects to CHE occurrence. Also, hypertension has a negative effect to the occurrence. Conclusion: With the results, it can be implied that elderly people with chronic disease are more needed in medical coverage and healthcare. Also, private insurance can play its role in protecting households from CHE. Therefore, it needs to conduct studies on CHE especially about different age groups, private insurance, and chronic disease.

In this paper, we propose an algorithm that can recognize the pattern regardless of the sensor position when performing EMG pattern recognition using circular EMG system equipment. Fourteen features were extracted by using the data obtained by measuring the eight channel EMG signals of six motions for 1 second. In addition, 112 features extracted from 8 channels were analyzed to perform principal component analysis, and only the data with high influence was cut out to 8 input signals. All experiments were performed using k-NN classifier and data was verified using 5-fold cross validation. When learning data in machine learning, the results vary greatly depending on what data is learned. EMG Accuracy of 99.3% was confirmed when using the learning data used in the previous studies. However, even if the position of the sensor was changed by only 22.5 degrees, it was clearly dropped to 67.28% accuracy. The accuracy of the proposed method is 98% and the accuracy of the proposed method is about 98% even if the sensor position is changed. Using these results, it is expected that the convenience of the users using the circular EMG system can be greatly increased.

Atherosclerosis and post-angiography restenosis are associated with intimal thickening and concomitant vascular smooth muscle cell (VSMC) proliferation. Obovatol, a major biphenolic component isolated from the Magnolia obovata leaf, is known to have anti-inflammatory and anti-tumor activities. The goal of the present study was to enhance the inhibitory effects of obovatol to improve its potential as a preventive or therapeutic agent in atherosclerosis and restenosis. Platelet-derived growth factor (PDGF)-BB-induced proliferation of rat aortic smooth muscle cells (RASMCs) was examined in the presence or absence of a newly synthesized obovatol derivative, OD78. The observed anti-proliferative effect of OD78 was further investigated by cell counting and [$^3H$]-thymidine incorporation assays. Treatment with 1-4 ${\mu}M$ OD78 dose-dependently inhibited the proliferation and DNA synthesis of 25 ng/ml PDGF-BB-stimulated RASMCs. Accordingly, OD78 blocked PDGF-BB-induced progression from the $G_0/G_1$ to S phase of the cell cycle in synchronized cells. OD78 decreased the expression levels of CDK4, cyclin E, and cyclin D1 proteins, as well as the phosphorylation of retinoblastoma protein and proliferating cell nuclear antigen; however, it did not change the CDK2 expression level. In addition, OD78 inhibited downregulation of the cyclin-dependent kinase inhibitor (CKI) $p27^{kip1}$. However, OD78 did not affect the CKI $p21^{cip1}$ or phosphorylation of early PDGF signaling pathway. These results suggest that OD78 may inhibit PDGF-BB-induced RASMC proliferation by perturbing cell cycle progression, potentially through $p27^{kip1}$ pathway activation. Consequently, OD78 may be developed as a potential anti-proliferative agent for the treatment of atherosclerosis and angioplasty restenosis.

This was a qualitative study on medical aid patients to understand the cause and process of statistical difference of health service utilization between medical aid and health insurance patients. The main results were the following; 1) There was few overuse of health service in medical aid patients. The reason of heavy utilization was mainly due to the complicated disease. Some of them were considered to overuse physical therapy and oriental acupuncture. 2) In case of medical aid patients, medical cost was paid by their welfare benefit of government or by the support of family or neighbors. They usually could not adequately use the services of uninsured benefit or large hospitals due to the cost. Some patients just endured the pain. There was still discrimination for medical aid patients in some medical institutions. 3) The health officials and institutions did not provide sufficient information to medical aid patients about the policy of medical cost support. 4) Health policies, such as selective clinic system, medial aid case management, approval of extended care, were considered to contribute in preventing unnecessary use of health service. However, this might limit adequate use of medical aid service. In conclusion, there is little evidence of overuse of health service for medical aid patients, which is different from the previous studies. A new plan is necessary, because medical aid patients thought that the necessary health service was not accessible to them.
