In this study, an exoskeleton-type robot is developed to assist frozen shoulder rehabilitation in a systematic and efficient manner for humans. The developed robot has two main features. The first is a structural feature: this robot was designed to rehabilitate both shoulders of a patient, and the three axes of the shoulder meet at one point to generate human-like ball joint motions. The second is a functional feature that is divided into two rehabilitation modes: the first mode is a joint rehabilitation mode that helps to recover the shoulder's original range of motion by moving the patient's shoulder according to patterns obtained by motion capture, and the second mode is a muscle rehabilitation mode that strengthens the shoulder muscles by suitably resisting the patient's motion. Through these two modes, frozen shoulder rehabilitation can be performed systematically according to the patient's condition. The development procedure is described in detail.

The purpose of this study was to investigate the main results of the nursing intervention program for reducing depression in menopausal women in Korea and to investigate the effects of systematic review of literature. Research methods were searched for RISS, KMbase, KoreaMed and KISS as domestic databases and limited to domestic papers published in last 10 years from 2006 to 2015. The analysis of 14 articles showed that exercised therapy among the various nursing intervention programs provided significant effects on reducing depression. The intervention methods provided oral education, demonstration training, and practical training, 6 sessions, 60 sessions per session, 5~10 weeks for intervention, and 6~12 weeks for intervention. Depression in menopausal women is not a temporary or short-term emotional state. So it is necessary to provide appropriate exercises that can be applied for their own, regardless of daily life.

Though science and technology can understood as a part of cultural system, the relationship of science/technology with culture is often viewed as contradictory or mutually exclusive by many scholars. Therefore, in the first section of the present paper, the nature of science and technology as a cultural form is examined. Here, science is viewed as a form of symbolic culture, while technology is regarded as a form of instrumental culture. In the second section, the contradictory relationship and/or tensions between science-technological system (instrumental culture) and cultural system (symbolic culture) within a society is discussed. In the final section of this paper, 'science culture' is conceptualized as a dynamic social process in which contradictory science sub-cultures of political system(state), economic system(cooperations), civil society (including academic community of scientists and other social organizations and movements), and cultural system are supposed to be coordinated. In conclusion, establishment of 'humanized science culture' and 'democratic science-culture movement' is proposed as an alternative way of resolving contradictory relationship between cultural system and science-technological system in the modern world.

Objective : The purpose of the study is to propose the treatment methods for problem of handwriting, micrographia in Parkinsons disease. Methods : For this purpose, foreign literatures on the subjects with Parkinsons disease was researched. Results : The results of this review is summarized as follows. The treatment methods for micrographia were applied to external cue and feedback among motor learning strategies in order to improve motor initiation. The external cues included visual, auditory, and verbal stimulations, and feedback strategy was visual stimulation. For writing with external cue or visual feedback, result in expanding the size of the letters in addition, writing task performance is maintained for a short period without those. Conclusion : Further studies are needed to examine the strategy maintained effect for long periods.

In the present study, we aimed to examine the effects of Schroth exercise(three-dimensional convergence exercise) on pulmonary function(vital capacity, and chest expansion), Cobb's angle, scoliometer angle, and erector spinae muscle activity. We examined 40 students with idiopathic scoliosis(Cobb's angle $10^{\circ}$). They were divided into the Schroth and conventional exercise groups, with 20 people in each group. Statistical analysis was performed by using SPSS 18.0 with a paired t-test(pre-post difference) and an independent t-test(between-group differnence). the result of were as follows; 1) After 8 weeks of Schroth exercise, significant improvements were observed in Cobb's angle, rib hump, vital capacity, chest expansion, and right thoracic longissimus muscle activity. 2) After 8 weeks of conventional exercise, a significant improvement was observed only in chest expansion. These findings indicate that the Schroth exercise program improved the Cobb's angle, rib hump, pulmonary function, and sEMG results. Therefore, this study demonstrates the usefulness of the Schroth exercise program for idiopathic scoliosis.

This research was performed to investigate the effects of participation in aqua exercise on blood composition and vascular compliance of mentally retarded persons. The targets of this research consisted of a control group of 12 people and an aqua exercise group of 12 people after selecting 24 mentally retarded males and aqua exercise group carried out an exercise program for 60 minutes per day and five days a week for 9 weeks. Weight, body fat percentage, blood composition and vascular compliance were measured in a preliminary inspection and the same items were measured in a post-inspection. The results of this measurement were as follows. Firstly, aqua exercise group showed a significant decrease in weight and body fat percentage (p<.05). Secondly, for blood composition, aqua exercise group showed a notable decrease in Total-Cholesterol, Triglyceride, and LDL-Cholesterol (p<.05) and a significant increase in HDL-Cholesterol (p<.05). Thirdly, aqua exercise group showed a notable increase in blood composition for both upper limbs and lower limbs (p<.05). Taken these results together, it was considered that a participation of mentally retarded persons in aqua exercise would prevent adult diseases and would have an affirmative influence on improvement of the quality of life.

The purpose of this study was to determine the clinical effects of blood flow regulation exercise for improving patients' health care and its usefulness as a rehabilitation model for various diseases by analyzing and examining the existing literature. A literature review of Korean academic journals published over a 10-year period, from 2010 to 2019, was conducted using words such as "blood flow regulation," "blood flow restriction," "low-intensity exercise," and "Kaatsu." Kaatsu is a blood flow regulation exercise developed in 1966 by Dr. Yoshiaki Sato of Japan. It is an efficient and effective exercise method that uses blood flow regulation bands that increase the secretion of growth hormones to develop muscles within a short time, improves blood circulation and metabolism to prevent and improve adult diseases, shortens the rehabilitation period, and improves cardiovascular function. The study participants consisted of 10 patients, of whom four were elderly, four had obesity, one was a stroke patient, and one was a trauma patient. The results of this study show that the blood flow regulation exercise, which is a low-intensity exercise, has the same effect as high-intensity exercise, which supports the evidence that it is a highly efficient exercise method for muscle development and rehabilitation of the elderly, adolescents, and patients with injuries who have difficulty in general exercising. For future studies, further reviews are necessary to verify the effectiveness of the exercise method according to blood flow regulation site and type of disease.

In this study, we perform the structural analysis of a floating offshore wind turbine tower by considering the dynamic response of the floating platform. A multibody system consisting of three blades, a hub, a nacelle, the platform, and the tower is used to model the floating wind turbine. The blades and the tower are modeled as flexible bodies using three-dimensional beam elements. The aerodynamic force on the blades is calculated by the Blade Element Momentum (BEM) theory with hub rotation. The hydrostatic, hydrodynamic, and mooring forces are considered for the platform. The structural dynamic responses of the tower are simulated by numerically solving the equations of motion. From the simulation results, the time history of the internal forces at the nodes, such as the bending moment and stress, are obtained. In conclusion, the internal forces are compared with those obtained from static analysis to assess the effects of wave loads on the structural stability of the tower.
