Purpose: The purpose of this study was finding out the effects of spinal stabilization exercise using Centaur which is a 3D spinal stabilization sports implement on Chronic low back pain patients over 8 weeks. Methods: 30 patients with DDD were observed during the study. Their average age was 66.88years, height was 152.12cm and average weight was 58.91kg, 4 males and 26 females were involved. 8 various investigations were performed and varied values were compared with reinvestigation done after having exercised 8 weeks using 3-D CENTAUR We used VAS(visual analog scale) in order to see the variation of pain intensity, MOI(modified oswestry index) in order to see limitation of daily life. Results: VAS was lessened from 7.57 to 2.63, limitation of routine life(MOS) from 23.48 to 11.30, there were remarkable differences statistically(p<0.05). As a result of muscular investigation for static spinal stabilization by 8 variations of body deflection, muscular strength were all increased and there were signigicant differences statistically(p<0.05). Conclusion: It has turned out that pain and limitation of routine life was lessened, as a result of 8 weeks exercise using CENTAUR, and deep muscular power was increased. Thus it has turned out that 3-D spinal stabilization exercise has an effect on the strengthening spinal muscles and alleviation of their pain for old patients with DDD.

This research was conducted to grasp the present condition of environmental management relating to Korea detector dogs that performed their duties such as detection and lifesaving. We directly conducted a survey throughout visit to five government agencies. In environmental management case, average length and width of kennels were 1.78 m and 3.50 m, respectively. Types of floor were searched as coating cement, tile, ucrete and concrete. Most of government agencies ventilated kennels using ventilation fan systems with natural ventilation. But there were differences between government agencies in frequencies of the sanitary management items. On the other side, major diseases of the German shepherd breed as a major detector dog were in order of arthritis, measles, earache, and dermatosis. And their daily training time was average 4 hours. Finally, it is thought that these results could be used as a basic data of standard breeding management manual of Korea detector dog.

This study was done to examine stressors that middle-aged men experience and how they deal with them. The subjects of this study are married men at the age of thirty five to fifty, the average age is 41.43(SD=5.46),27,580,070 income,1.14 (58= 1.21) children. and married to 13.87 years. The average of every stressor of middle-aged men turned out to be similar, but they are aware of their physical stress at most, stress from family and mentality ranks at second, and stress at job is the lowest. The coping behavior towards stress shows direct-active behavior at most, direct-inactive behavior and indirect-active behavior are in the close level, and indirect-inactive behavior takes the lowest portion. From the analysis, there were differences in stressors and dealing behaviors according to individual character and the family, they use different coping ways depending on stressors. Men became to be highly conscious of the crisis of the middle-aged life in rapidly changing society and family. Therefore, we need to figure out stressors they go through and develop the strategies to cope with stress so that they could support middle-aged men's quality of life.

Purpose: The objective of this study was to develop a multilayer perceptron (MLP) model to estimate solar radiation using a solar module. Methods: Data for the short-circuit current of a solar module and other environmental parameters were collected for a year. For MLP learning, 14,400 combinations of input variables, learning rates, activation functions, numbers of layers, and numbers of neurons were trained. The best MLP model employed the batch backpropagation algorithm with all input variables and two hidden layers. Results: The root-mean-squared error (RMSE) of each learning cycle and its average over three repetitions were calculated. The average RMSE of the best artificial neural network model was $48.13W{\cdot}m^{-2}$. This result was better than that obtained for the regression model, for which the RMSE was $66.67W{\cdot}m^{-2}$. Conclusions: It is possible to utilize a solar module as a power source and a sensor to measure solar radiation for an agricultural sensor node.

Objects: In this study, we analyzed the correlation between stress and depression related to the quality of life of one elderly household, and analyzed the influence of stress and depression on the quality of life. In this study, I tried to make a plan for improving the quality of life for one elderly. Methods: In this study, the frequency and percentage according to the general characteristics of one elderly household were frequency analyzed. And the mean and standard deviation of stress, depression, quality of life were analyzed on average. And continuous analysis of stress, depression, quality of life, etc., conducted a technical analysis. Relationship to stress, depression, quality of life, correlation analysis was done. The effect of stress and depression on the quality of life was linear regression analysis. SPSS Version 23.0 was used for analysis. Result: Increased stress and increased depression in elderly single households was a static (+) correlation. And the results of the regression analysis showed that the higher the stress and depression of one elderly household, the lower the quality of life. Conclusion: For the improvement of the quality of life of one elderly household, the government should support stress and depression prevention programs according to sex, age, number of chronic diseases.
