Parkinson's disease is a degenerative neurological disease that affects even basic daily life movements due to impairment of body function caused by a lack of dopamine, which is charge of the body movement. Presently, it is hard to cure Parkinson's disease entirely with medical technology, so movement therapy as a solution to delay and prevent disease is getting more attention. Therefore, this study aims at desiging and disseminating a body movement program that concentrates on individual self-care and balacing the state of body and mind by applying the Feldenkrais Method® to patients with Parkinson's disease. The Feldenkrais Method® is a mind-body perceptual learning method using body movements. It is a methodology that re-educates the nervous system by connecting the brain and behavior as a function of neuroplasticity. In this study, the body movement program developed and verified by the researcher was modified and supplemented with a focus on the self-awareness of the Feldenkrais Method®. A 24-session physical exercise program was composed of 5 stages to improve the self-management ability of patients with Parkinson's disease. The stages include self-awareness, self-observation, self-organization, self-control, and self-care. The overall changes recognize one's condition and improve one's ability to detect modifications in the internal sense and external environment. In conclusion, the body movement program improves the body movement program improves mental and physical functions and self-care for Parkinson's disease patients through the Feldenkrais method. The availability of the program's on-site applicability remains a follow-up task. Furthermore, it is necessary to establish a systematic structure to spread it more widely through convergent cooperation with the scientific field applied with metaverse as a reference for the wellness of the elderly.

The study mainly discusses appreciation of interactive art works seen from the perspective of play attributes that make spectators glimpse the truth of things. The general studies of interactivity, as one of remarkable features in contemporary art, are regarding the relation between the effects of digital media and interactivity as well as video games. From the preceding discussion, I analyze the effects of the appreciating interactive art works which are focused on new sensory systems, the methods to intuit the essence of the art works. Based on the concept, as I investigate the play attributes found in the interactive art works, this study gives attention to the possibility that if the spectators can reach the inherent aspects of interactive art works, while interacting them. Thus to discuss the properties of the play, this article studies play concept of Johan Huizinga(1872-1945), psychologist and anthropologist and play theory of Hans Georg Gadamer(1900-2002) who considers play as a metaphor for art. As Huizinga thinks acting is the important attribute of play, Gadamer argues whenever the term 'play' is used, we should think about 'to-and tro movement' and the movement is absence of goal as well as endlessly renews through repetition. Then what we should pay attention to, seeing the essence of art and play as similar? That is, Gadamer claims, we can understand the truth of things through the play. To apply the play concept to the interactive art works, I research the works of Maurice Benayoun(1957 - ), French interactive artist. By employing interactivity, he attempts to extend and affect the experience of his art works to one of social phenomenon. Striving this, spectators can widen and deepen the breadth of their intuition and recognize the essence of art works. It is the interactive art works that can be the apex of the transformation of structure from the play to the art. The endless repetitive process of play, which is free creation-annihilation process, is similar with the interactive experience of spectators that is variable, de-centered, and multi-sensory. The pure action of the play lets us recognize, sense and accept the world and through the system of interactive art experience, we can expand the horizons of perception. Interactive art works with these play attributes are capable of playing the role that the spectators glimpse the truth of things and experience the world around them.

This paper presents the control algorithm of active walking aids estimating external torque of the wheels from user's will. Nowadays, interest of the walking aids is increased according to the increase in population of elder and handicapped person. Although many walking aids are developed, most of walking aids don't have any actuators for its movement. However, general walking aids have weakness for its movement to upward/download direction of slope. To overcome the weakness of the general walking aids, many researches for active type walking aids are being progressed. Unfortunately it is difficult to precision control of walking will during its movement, because it is not easy to recognize user's walking will. Many kinds of methods are proposed to recognize of user's walking will. In this paper, we propose control algorithm of walking aids by using torque estimation from wheels. First, we measure wheel velocity and voltage at the walking aids. From these data, external forces are extracted. And then walking will that is included by walking velocity and direction is estimated. Finally, walking aids are controlled by these data. Here, all the processes are verified by simulation.

This paper presents the study about MGV(Magnetic guidance vehicle) with up-and-down rotating type differential drive unit. Previous MGV needs the landmarks to get the driving information and additional sensor to recognize the landmarks except for localization sensor. Previous MGV requires at least 2 drive units when common fixed differential drive unit is used because it occurs the problems with driving control and localization error from imbalance of the MGV's weight. To solve such problems, we propose the MGV using up-and-down rotating type differential drive unit. Proposed MGV recognizes the driving information from the pattern which is consisted of both pole of magnet without landmarks and additional sensors, and it control the backward movement using up-and-down rotating type differential drive unit instead of common drive units. Proposed MGV considers KF(Kalman filter) to improve the localization accuracy. To verify the performance of proposed method, we designed MGV for the experiment. As the results, we can confirm the performance of propoesed method to recognize the pattern and to control the backward movement. With respect to localization, proposed method has the less RMSE about 5.6904 mm than previous method.

This is a qualitative study conducted to understand and explain the experience of nursing students' exploring historic sites of independence movement overseas. The study's participants were 24 nursing students in the first and second graders who participated in a program to explore the historic sites of independence movement overseas at a college in C County, Gyeongsangbuk-do. The data collection period was from December 23, 2017 to December 25, 2017. The data collection was carried out in an open self-reporting process, and the collected data were analyzed using the qualitative content analysis method of Krippendorff[13]. Based on the analysis of the experience of nursing students' exploring historic sites of independence movement overseas 19 sub-theme, 10 themes, and 4 categories were derived. The four categories are "Our History Represented in the wake of the independence movement", "Footprint projected of an independent activist ", " Rage Boiling But Hope Remaining", "blooming patriotism through reflection". The results of this study provided an understanding of nursing students' experience in exploring the historical sites of independence movement and have shown that nursing students had the opportunity to recognize the history of independence movements, inspire patriotism and reflect on their attitude as nurses. In addition, institutional efforts and resources should be supported to address the lack of policies on the preservation of the historic sites for independence movements overseas, which are dependent on the private sector.

There has been a lot of attention paid recently to analyze dynamic human gestures that vary over time. Most attention to dynamic gestures concerns with spatio-temporal features, as compared to analyzing each frame of gestures separately. For accurate dynamic gesture recognition, motion feature extraction algorithms need to find representative features that uniquely identify time-varying gestures. This paper proposes a new feature-extraction algorithm using temporal self-similarity based on a hierarchical human model. Because a conventional temporal self-similarity method computes a whole movement among the continuous frames, the conventional temporal self-similarity method cannot recognize different gestures with the same amount of movement. The proposed model-based temporal self-similarity method groups body parts of a hierarchical model into several sets and calculates movements for each set. While recognition results can depend on how the sets are made, the best way to find optimal sets is to separate frequently used body parts from less-used body parts. Then, we apply a multiclass support vector machine whose optimization algorithm is based on structural support vector machines. In this paper, the effectiveness of the proposed feature extraction algorithm is demonstrated in an application for taebo gesture recognition. We show that the model-based temporal self-similarity method can overcome the shortcomings of the conventional temporal self-similarity method and the recognition results of the model-based method are superior to that of the conventional method.

The representative study of Patellofemoral Joint Merchant method can show the view for inspection of the sulcus angle, congruence angle and diagnose whether there are the vertical fractures and recognize the degree of dislocation and patella subluxation. However, anatomical correlation about the degree of knee joint curvature changes during position adjustment and distortion of the image reduces reproducibility. In order to resolve these problems, Merchant method needs to use assisting device which reduces the occurrence of repeat projection and effectively to increase unification of examination and the consistency of the image. However, there are disadvantages for patients who take other examinations. For example, they have to change the position for every examination and it might cause the patient's discomfort and increase of examination time. In this study, we newly devised commercial assisting device which improves the reproducibility of the images and reduces inconvenience of patients movement. Further research should be taken to obtain a image without patient's movement and to reduce the time of the examination than existing method.

Throughout the Chinese sphere, that is, in the People's Republic of China and Taiwan, tea houses, tea stores, and tea meditation groups often without a particular religious orientation have appeared in the past decades. Tea lovers groups with various philosophical discussions appear throughout cyberspace, where people show their appreciation for tea as a drinkable delicious product and a spiritual tool. The question to be asked here is whether it should be recognized as a religious or spiritual practice agent in and of itself? Should we then talk about the present-day movement of teaism? If we do recognize this as a spiritual phenomenon, should it then be labeled as a New Religious Movement? The trajectory of tea in China is intrinsically connected to religious traditions. This connection is historical, yet it plays a part in the contemporary religious and spiritual sphere. The article explores the continuation and developments of tea culture in the context of the religious sphere of China, looking at practices connected to tea of communities, religious organizations, and individuals. The author explores how tea drinking, commercializing and tea related practices intersect with politics, materiality, and spirituality in contemporary society. In this context it is then argued that tea is a cultural element, religious self-refinement tool, and an active material agent with social-political capacities. The study includes historical narratives, ethnographic data, and literary sources about tea, making up a genealogy of tea which encompasses ritualistic aspects, economic aspects, and power relations related to tea in Chinese society.

For understanding of anatomy, physiology, and diseases of human TMJ, it is required to evaluate quantitatively the movement of the disc and condyle head of mandible. The histologic section of cadaver TMJ were examined, and the magnification of the MR image and its details of anatomy were evaluated. And then a quantitative analytic method, by comparing the Sectograph and the MR image of vital human TMJ, was proposed. For this study, 15 subjects(Male, 24~35years) were selected from a prosthodontic examination randomly, and each subject’s five interocclusal rubber registration records were made on the ICP, and 5, 10, 15, and 20mmjaw opening positions. All subjects were radiographed with a Denar Quint Sectograph Image System(Denar Corp., USA), and imaged with a MRP-20EX MR Image System(0.2T, Permanent Magnet Type, Hitachi Medical Corp., Japan) using an 100mm diameter bilateral type surface coil. These images were traced on the acetate tracing paper, and analyzed In this study, the findings led to the following conclusions. 1. In comparison of the histologic section of autopsy specimen with the MR image at the same section, the size(dimension) of MR image was 70% of the real one. It was possible to recognize the shape of articular disc, anterior and posterior attachments, and adjacent soft tissues, because of the excellent reproducibility of anatomical structure. 2. When we compared the amount of joint space on MR image with that of joint space on sectograph, the amount of joint space on sectograph was significantly greater than that of joint space on MR image, except at the top of condylar head. 3. The position of minimum joint space on sectograph at intercuspal position didn't coincide with the middle position of articular disc on MR image, and was approximately in the anterior third of posterior band of articular disc. 4. The amount of condylar movement on MR image at opening movement was greater than that of articular disc movement. From Intercuspal position to 5mm jaw-opening movement, the condylar movement showed hinge one, and over the range 5mm jaw-opening it suggested hinge & translatory one. 5. In terms of area variation of articular disc measured on MR image in sagittal plane, the area of posterior band increased with increasing the amount of Jaw opening, but the area of anterior band decreased conversely.

Many studies have examined robot control using human bio signals but complicated signal processing and expensive hardware are necessary. This study proposes a method to recognize a human's hand motion using a low-cost EMG sensor and Flex sensor. The method to classify movement of the hand and finger is determined from the change in output voltage measured through MCU. The analog reference voltage is determined to be 3.3V to increase the resolution of movement identification through experiment. The robotic hand is designed to realize the identified movement. The hand has four fingers and a wrist that are controlled using pneumatic cylinders and a DC servo motor, respectively. The results show that the proposed simple method can realize human hand motion in a remote environment using the fabricated robotic hand.
