Purpose : The purpose of this article was to review the literature on mirror neuron system with reference to its functional diversity in stroke rehabilitation.. Method : This review outlines scientific findings regarding different neurophysiological properties in mirror neurons, and discusses their involvement in process of stroke rehabilitation. Result & Conclusions : Mirror neurons were first discovered in macaque monkey. These neurons, like most neurons in F5 areas in premotor cortex, fired when an individual performs an action, as well as when he/she observes a similar action done by another individual, although originally fired only during action execution. Mirror neurons form a network for motor planning and initiating of motor action. Thus, in stroke rehabilitation based on the mirror neuron-action observation, motor imagery, observation with intent to imitate and imitation-may help activate mirror neuron system for improved outcome of physical therapy. These studies provide a scientific theoretical basis and discuss for the use of mirror neuron system as a complement to clinical physical therapy in stroke rehabilitation.

Natural language processing (NLP) is utilized to understand a natural text. Text analysis systems use natural language algorithms to find the meaning of large amounts of text. Text classification represents a basic task of NLP with a wide range of applications such as topic labeling, sentiment analysis, spam detection, and intent detection. The algorithm can transform user's unstructured thoughts into more structured data. In this work, a text classifier has been developed that uses academic admission and registration texts as input, analyzes its content, and then automatically assigns relevant tags such as admission, graduate school, and registration. In this work, the well-known algorithms support vector machine SVM and K-nearest neighbor (kNN) algorithms are used to develop the above-mentioned classifier. The obtained results showed that the SVM classifier outperformed the kNN classifier with an overall accuracy of 98.9%. in addition, the mean absolute error of SVM was 0.0064 while it was 0.0098 for kNN classifier. Based on the obtained results, the SVM is used to implement the academic text classification in this work.

This study is to propose an acceptance model that explains the use of telemedicine effects for chronic disease. For this purpose, the effect factors and variables for Technology Acceptance Model (TAM) were investigated through a structural equation model by performing a sample survey for 210 senior patients who are under treatment with telemedicine in Kangwon area in 2013. The findings from the results are as follows: 1) perceived usefulness and perceived easy of use influence the intent to use telemedicine; 2) open-minded patients group is more positive to the easy of use and usefulness for the telemedicine; 3) it matches with the previous research that shows the trust in telemedicine system is affected by the experience for practical use of information; 4) it is known that the external control factors for health affect perceived usefulness positively. This study contributes to optimize the TAM by verifying the acceptance of telemedicine system in a rural community.

The use of lightweight aggregate (LWA) instead of ordinary aggregate may make lightweight aggregate concrete, which possesses many advantages such as lightweight, lower thermal conductivity, and better fire and seismic resistance. Recently the developments of LWA have been focused on using industrial wastes as raw materials to reduce the use of limited natural resources. In view of this, the intent of this study was to apply Taguchi optimization technique in determining process condition for producing synthetic LWA by incorporating waste thin film transition liquid crystal displays (TFT-LCD) glass powder with reservoir sediments. In the study the waste TFT-LCD glass cullet was used as an additive. It was incorporated with reservoir sediments to produce LWA. Taguchi method with an orthogonal array L16(45) and five controllable 4-level factors (i.e., cullet content, preheat temperature, preheat time, sintering temperature, and sintering time) was adopted. Then, in order to optimize the selected parameters, the analysis of variance method was used to explore the effects of the experimental factors on the performances (particle density, water absorption, bloating ratio, and loss of ignition) of the produced LWA. The results showed that it is possible to produce high performance LWA by incorporating waste TFT-LCD glass cullet with reservoir sediments. Moreover, Taguchi method is a promising approach for optimizing process condition of synthetic LWA using recycled glass cullet and reservoir sediments and it significantly reduces the number of tests.

Social scientists in North America, especially anthropologists, folklorists and linguists, who focus on the study language use and its connection to society, use a variety of labels to describe what they do. Among the best known are 'anthropological linguistics' , 'linguistic anthropology', and 'sociolinguistics'. All of these labels imply that their focus is on the study of language usage in society and culture for their teaching, research and publications. In this paper I am examining the intellectual issues and history that underlie the differences in the labels. The differences and similarities that characterize them are discussed. The author proposes 'linguistic anthropology' as the most useful disciplinary terminology if the study of language combined with culture is to be 'community-centric' and not only 'profession-centric' . He encourages a renewed focus on working with communities. Also, a need to find ways to engage Indigenous members of minority language communities more actively should be a primary goal in the process of 'academic' language work. This is important due to the loss rapid extinction of the many of the world's languages. The author points out that it does matter what we call the work we do, as a label may carry a message of meaning, intent and focus.

Topology optimization has been widely used for the optimal structure design for weight reduction and high performance. Since the result of three-dimensional topology optimization is represented by the discrete material distribution in finite elements, it is hard to interpret from a design point of view. In this paper, the method for interpreting three-dimensional topology optimization resuIt into a series of cross-sectional curve representation is proposed and interfaced with the existing CAD system for the practical use. The concept of node density and virtual grid is introduced to transform element density values into grid density and material boundaries in each cross section are identified based on the element volume rate to satisfy the amount of material specified in the original design intent. Design exampIes show that three-dimensional topology result can be converted into a form of curve CAD model and the seamless interface with CAD software can be achieved.

In the case of Korea, both of modern medicine and oriental medicine are admitted as medical practices in the system. In other words, healthcare system is dualized. However, medical practice that corresponds to oriental medicine in Korea is substitution of medical practice in cases of foreign countries. For use of medical devices, it is provided only for doctors and medical technician relevant to use. Particularly, although oriental medicine is recognized as orthodox medicine in terms of the features of Korean medical system, superintendency of oriental doctors is not identical with that of doctors for use of medical devices and superintendency toward medical technicians. Recently, Cheongju District Court decided that superintendency of oriental doctor upon physical therapist is not acknowledged. It can be said that the judgement is opposed to the original verdict which judged that oriental doctors' employment and guidance of oriental doctors upon physical therapist is permissible. Hence this study aimed to review on domestic medical law system, which is dualized, roles of medical professionals, intent of the medical license system, provisions related to medical technician law and relevant precedents. Regulations on practices other than licensed practices by medical professionals are made because medical practices may affect on danger toward life and body of human and public health also. Therefore, the nation regulates medical professionals having licenses to perform medical practices within the range of the licenses. It is clearly prescribed that medical technicians may perform medical practices under instructions of doctors or dentists pursuant to the medical technician law. In addition, the court also judges that it is out of the license of oriental doctors if they use CT devices and limits the use of modern medical devices by oriental doctors. That is to say that it limits oriental doctors' employment of medical technicians and pursuant of oriental doctors on medical technicians as well.

Cloud computing technology is expanding its services to individual consumers through storage and applications. This study aims to compare the predisposing factors that affect the perceived value and the intention to use between users who have used or experienced services and those who have never experienced services from the perspective of benefit and sacrifice based on the value-based acceptance model. The results showed that the sacrifice factor (perceived cost) had a significant effect on perceived value and perceived value had a significant effect on intention to use, but showed a difference in perceived benefit. Perceived usefulness, ubiquity, and network effects had significant impact for experienced users' perceived value, but for inexperienced users, ubiquity did not have significant impact. In addition, usefulness was the most significant factor for experienced users while network effect was the same for inexperienced users. The results of this study suggest that consumers' intention to use personal cloud service is evaluated as a benefit and sacrifice point and a new attempt to re-examine the role of previous experience.

The purpose of this study is to investigate the factors that affect the perceived awareness and the intention of continuous use by FinTech users and system characteristics. Data collection was carried out by targeting and surveying 600 people living in Gwangju, and office workers using smartphones. As a result, first, self-efficacy, innovation, and fitness for Fin-Tech services were found to influence the degree of perceptual awareness and intent to use of Fin-tech service users. Second, the system characteristics have a positive effect on perceived awareness and intention of using FinTech service. Third, the hypothesis about the dangers in the user attributes and system properties were dismissed. It seems that the priority concern was regarding the leakage of personal information and security as privacy and the increasing damage cases of financial fraud by electronic financial transactions spill. Therefore, in order to spread FinTech services, it would be effective if a Fin-Tech service strategy could eliminate inconveniences such as the risk of hindering convenience and intention to use by the marketing strategy established by the company.
