The idea I set my thesis upon was to develop a methodology for the visually impaired to perceive an environment through their other senses. Since the Blind perceive spatial relationships by combined association of their other senses, it was essential to create a setting where their senses can be amplified. Thus this garden was designed to accommodate two or more of blind person's senses at once to provide more of '3-D' spatial relationship. The main goals of this thesis are, first, to create a place where the Blind can enjoy and nurture their own specific interests. Second, to reveal the nature in its allowing individual analysis and interpretation of a garden. Third, to move away from the prejudice of gardens for the Blind being made of only touching and smelling. To achieve these goals, the most important task was to establish a sense of space. In order to do so, five principles were used; Perspective, Enclosure, Light/Shade, Form, and Environment. After all, the garden for the Blind does not proclaim its purpose in loud terms nor in obvious manner. It should attempt to provide joy, serenity, and activity; a freedom to choose, recognize and analyze nuances of garden, the rhythm of enclosure and openness to experience variety, also to delight in subtle changes and to just imagine.

Purpose: The purpose of this study was to recognize the importance of balance in order to minimize daily living restrictions and to prevent falls due to aging, and develop an eight-week theraband exercise program to benefit the elderly. Method: A total of 20 elderly participants were divided into two groups. Group A used warm-up and finishing exercises for eight weeks including stretching and rhythm exercises conducted in a theraband exercise. Group B performed no exercises. Both A and B groups at weeks 1, weeks 4, weeks 8 were measured for deltoid and quadriceps femoris strength, balance and proprioception. Result: There was a significant difference in deltoid and quadriceps femoris muscle strength, balance and proprioception between Group A and Group B(p<0.05). Conclusion: The results of this study show that theraband exercises are thought to be able to contribute to the promotion of deltoid and quadriceps femoris muscle strength, balance and proprioception. It also contributes to minimize activity of daily living restrictions and prevent fall down in elderly. However in this study, generalization has been limited because of exercise duration, limited number of experiments and intensity modulated of theraband.

Objectives: The purpose of this systematic review was to investigate the clinical effects of neurofeedback training on reducing anxiety. Methods: Eight databases were used to extract clinical reports on neurofeedback intervention for anxiety reduction published until 2016. We analyzed the characteristics of selected studies and evaluated biases using the Risk of Bias (RoB) assessment. Results: A total of 22 clinical trials were extracted for the analysis. The risk of bias in most studies was high or unclear. The Chinese Classification of Mental Disorders-3 (CCMD-3) was the most frequently used diagnostic criteria, the Hamilton Rating Scale for Anxiety (HAMA) was the most frequently used assessment tool, and the alpha wave activity increase, sensorimotor rhythm (SMR), and theta wave training were the most frequently used intervention methods. All papers showed a statistically significant decrease of anxiety symptoms; however, significant adverse events were not reported. Conclusions: Neurofeedback intervention might be beneficial for reducing anxiety. However, the quality of the studies used in the analysis was low, and the heterogeneity of the population and interventions was revealed. Therefore, more scientifically designed clinical studies regarding neurofeedback training are required.

Human can learn how to shape their brain electrical activity in a desired direction through continuous feedback of the electroencephalogram (EEG), and this technique is known as Neurofeedback (or EEG biofeedback), which has been used since the late 1960s in clinical applications. In this study, a portable wireless EEG (named wEEG) has been designed and implemented, which consists of a mobile station (a wireless two-channel EEG acquisition device) and a base station (a bridge between mobile station and computer). Moreover, a SensoriMotor Rhythm (SMR) training system was also implemented with the wEEG for enhancing attention with virtual environment. Experiment results based on 16 volunteers' (8 females and 8 males, average age is $27{\pm}4$) were reported in this paper. The results show that the SMR ratio of 87.5% subjects increased about 0.7% in training status than that in the stable status. With the proposed system, many training protocol scan be designed easily and can be done at home in our daily life conveniently. Additionally, the proposed system will be useful for disabled and aged people.

The purpose of this study was to examine how musical pieces were presented in music activities on the Teacher's Guidebooks in order for young children to experience the aesthetics of music. For the purposes of this research, the ways to address musical elements and the music activities of 100 musical works in the Teacher's Guidebooks were analyzed. In addition, the aesthetic qualities of the same musical pieces presented by the sound sources were examined. Following this, an analysis of the relationship between the elements used and the aesthetic qualities of the music was carried out by comparing the previous analysis. The results were as follows. First, melody (38.1%), rhythm (29.0%), and timbre (20.5%) were the most utilized elements of musical works in such activities. Secondly, the most utilized method to present music activities was singing. Among 100 musical pieces, 74 pieces used singing activities. Next, the most audible aesthetic quality from sound sources was that of the melody, presented in 69 pieces (46.6%) among 100 musical works. Lastly, among 100 musical works, at least 64 pieces were matched with more than one, whereas 34 did not.

Stroke is a leading cause of death in most developed countries and some developing countries including South Korea. It is well known that stroke has is related in some way with several sleep disorders. At first, the onset time of stroke varies according to circadian rhythm. Early morning is the most prevalent time and late evening the least. The changes of blood pressure, catecholamine level, plasminogen activity and aggregation of platelet during sleep have been suggested as possible mechanisms. Sleep apnea (SA), a representative disorder in the field of sleep medicine, is found in more than 70% of acute stroke patients compared to 2-5% of the general population. Various sleep related breathing disorders occur after stroke and snoring is a distinct risk factor for stroke. So the relationship between stroke and SA is obvious, but the cause and effect are still not clearly known. Also, stroke may cause many sleep related problems such as insomnia, hypersomnia, parasomnia and changes in sleep architecture. Patients, family members and even medical personnel often ignore stroke-related sleep problems, being concerned only about the stroke itself. The clinical impacts of sleep problems in stroke patients may be significant not only in terms of quality of life but also as a risk factor or prognostic factor for stroke. More attention should be paid to the sleep problems of stroke patients.

Purpose: There has been an increase in the number of prehospital cardiac arrests due to increases in both cardiovascular diseases and the average age of the population, We performed this study to identify the proper resuscitation technique and AED to be used to increase the survival rate in prehospital cardiac arrest. Methods: We studied 57 victims with prehospilal cardiac arrest by EMT's Reports form January to December, 2004. Results: Fifty-seven of 92 victims were trasported with ECG in prehospital cardiac arrest. Ventricular fibrillation(VF)/ ventricular tachycardia was 56.2%, asystole was 33,3%, and pulseless electrical activity(PEA.) was 10.5% in initial rhythm analysis, There weren't attempt CPR in 14.0%. Twenty of the 32(62.5%) were shocked by AED for the adequacy method. There were no statistical differences the transportation time. Conclusion: With the increase in cardiovascular disease and old age, the number out-of-hospital cardiac arrests has risen accordingly. However, there were lack of CPR by bystander, defibrillation, advanced cardiac life support(ACLS) in prehospital stage. To improve the adequancy of basic life support and to increase the performance of ACLS, especially AED, we must create challenges to develop new protocols in prehospital care.

This article is an addendum to the authors’ previous article (Kim, J. et al. (2008) Plant Cell 20, 307-319). The instrumentation and software described in this article were used to analyze the circadian leaf movement in the previous article. Here, we provide detailed and practical information on the instrumentation and the software. The source code of the LMA program is freely available from the authors. The circadian clock regulates a wide range of cyclic physiological responses with a 24 hour period in most organisms. Rhythmic leaf movement in plants is a typical robust manifestation of rhythms controlled by the circadian clock and has been used to monitor endogenous circadian clock activity. Here, we introduce a relatively easy, inexpensive, and simple approach for measuring leaf movement circadian rhythms using a USB-based web camera, public domain software and a Leaf Movement Assay (LMA) program. The LMA program is a semi-automated tool that enables the user to measure leaf lengths of individual Arabidopsis seedlings from a set of time-series images and generates a wave-form output for leaf rhythm. This is a useful and convenient tool for monitoring the status of a plant's circadian clock without an expensive commercial instrumentation and software.

Being able to monitor the heart will allow the diagnosis of heart diseases for patients during daily activities, and the detection of burden on the heart during strenuous exercise. Furthermore, with the help of U-health technology, immediate medical action can be taken, in the case of abnormal symptoms of the heart in daily life. Therefore, it appears to be necessary to develop the corresponding technology to monitor the condition of the heart daily. In this study, a novel wearable smart system was proposed, to monitor the activity of the heart in daily life, and to further evaluate the rhythm of arrhythmia. The wearable system includes three modified bipolar conductive fiber electrodes in the chest part, which can resolve the reduction problem of the magnitude of the signal, by magnifying the signal and removing the noise, to obtain high affinity and validity for medical-type usage (<0.903%). The biological signal acquisition and data lines, and the signal processing engine and communication consist of a conductive ink, and the pic18 and ANT protocol nRF24AP2, respectively. The proposed algorithm was able to detect a strong ECG, signal and r-point passing over the noise. The confidence intervals were 96 %, which could satisfy the requirement to detect arrhythmia under the unconstrained conditions.
