This study was conducted to test whether a comprehensive health promotion program for promotion strategies and knowledge about the disease, thus leading to the improvement of health status by using repeated measure of quasi- experiment design. Eighteen RA patients who visited the RA clinic of an university hospital located in Inchon were invited to participate in the CHPPRA. According to the study results, it was shown that the CHPPRA had significant effects on the patients' health status such as pain, depression, and functional disability. Also, that the improvement of health status was achieved by a positive change in the four health promotion strategies, which consisted of goal setting, positive thinking, exercise, and knowledge about the disease. Goal setting, positive thinking, and knowledge about the disease could also affect the patients' depression. Thus it can be interpreted that the improvement of these strategies may result in a remarkable decrease of depression. In addition, alleviation of functional disability may be due to increase of exercise. However although the strategies which were directly associated with pain management were not significantly improved, pain was significantly reduced. On the other hand, the study result showed that the other health promotion strategies included in CHPPRA such as pain management, positive thinking, stress management, asking for assistance and communication were not significantly increased. although the health status such as pain, depression, and functional disability, which are final goals of the program, were significantly improved through the exposition of patients to those health promotion strategies.

It is the most important thing at present for physicians to posses the qualification of medical professionalism. A lot of medical schools have made all-out efforts to develop leaders of medicine, who will be able to meet the needs of medical professionalism in this complex medical environment. The purpose of this study is to review the cognitive base of medical professionalism leading the curriculum development of medical professionalism. The discussion of medical professionalism started in the 20th century. During the 1960s, there were attempts to reshape the concepts and attributes of medical professionalism. The government began to intervene in the autonomy of physician and the self regulation policy of medical society in 1970s. Physician may be asked to play as a healer and professional (what?) during their medical practice. The fundamental role of healer such as care, compassion, honesty, integrity, confidentiality, ethical behaviors, and respect with patients were nothing fresh to tell even though the age was changed. The attributes of professional which are physician's autonomy, self regulation, teamwork, and responsibility to society has been changed dramatically over the past five decades. In general, medical educators agreed that professionalism is demonstrated through a foundation of clinical competence, communication skills, and ethical and legal understanding, upon which is built application of the principles of professionalism: excellence, accountability, altruism, and humanism. If physicians fail to show professionalism in society, they will confront the crisis which can be under the government control. The only way to keep their autonomy is to practice medical professionalism. So far today, medical schools have laid more stress on competence than value standards in educational systems and it was restricted for medical students to learn the value standards for medical practice. To understand and practice the medical professionalism, it is the most realistic way to solve the complicated medical problems.

As information and communication technologies (ICTs) become more advanced, consumers are able to experience retailing activities such as searching for products and services in online retail shops and for Internet-exclusive branded contents. Specifically, fashion retailers are facing the need to develop more novel experiential design than one another to maximize customers' experience in Internet websites and secure sustainable competency. Confirming methods of organic integration of experiential and visual features of both online and mobile channels is an important aspect of the study of extended consumers' interfaces of retail channels. Mehrabian and Russell's stimulus-organism-response (S-O-R) paradigm and Sugiyama and Andree's attention, interest, search, action, and share (AISAS) model were used for this research. Specifically, the present study considered the effect of e-commerce website features on consumers' emotional reactions (pleasure and arousal) and the consequent impact on online consumer behaviors (search, action, and share). Hence, plus the self-reported survey methods, each subject's psychophysiological indicators (i.e., pleasure and arousal) were measured to obtain more objective and reliable data and to redeem the results of the self-reported survey. Findings revealed the implications of the e-commerce website feature by comprehending the S-O-R paradigm and AISAS model and extending the understanding of the role of variables associated with comprehended frameworks based on psychophysiological data.

Communication occurs through verbal elements, which usually involve language, as well as non-verbal elements such as facial expressions, eye contact, and gestures. In particular, among these non-verbal elements, gestures are symbolic representations of physical, vocal, and emotional behaviors. This means that gestures can be signals toward a target or expressions of internal psychological processes, rather than simply movements of the body or hands. Moreover, gestures with such properties have been the focus of much research for a new interface in the NUI/NUX field. In this paper, we propose a method for recognizing the number of fingers and detecting the hand region based on the depth information and geometric features of the hand for application to an NUI/NUX. The hand region is detected by using depth information provided by the Kinect system, and the number of fingers is identified by comparing the distance between the contour and the center of the hand region. The contour is detected using the Suzuki85 algorithm, and the number of fingers is calculated by detecting the finger tips in a location at the maximum distance to compare the distances between three consecutive dots in the contour and the center point of the hand. The average recognition rate for the number of fingers is 98.6%, and the execution time is 0.065 ms for the algorithm used in the proposed method. Although this method is fast and its complexity is low, it shows a higher recognition rate and faster recognition speed than other methods. As an application example of the proposed method, this paper explains a Secret Door that recognizes a password by recognizing the number of fingers held up by a user.

In the companion paper, the composition and structure of the MATDYMO (Multi-Agent for Traffic Simulation with Vehicle Dynamic Model) were proposed. MATDYMO consists of the road management system, the vehicle motion control system, the driver management system, and the integration control system. Among these systems, the road management system and the integration control system were discussed In the companion paper. In this paper, the vehicle motion control system and the driver management system are discussed. The driver management system constructs the driver agent capable of having different driving styles ranging from slow and careful driving to fast and aggressive driving through the yielding index and passing index. According to these indices, the agents pass or yield their lane for other vehicles; the driver management system constructs the vehicle agents capable of representing the physical vehicle itself. A vehicle agent shows its behavior according to its dynamic characteristics. The vehicle agent contains the nonlinear subcomponents of engine, torque converter, automatic transmission, and wheels. The simulation is conducted for an interrupted flow model and its results are verified by comparison with the results from a commercial software, TRANSYT-7F. The interrupted flow model simulation is implemented for three cases. The first case analyzes the agents' behaviors in the interrupted flow model and it confirms that the agent's behavior could characterize the diversity of human behavior and vehicle well through every rule and communication frameworks. The second case analyzes the traffic signals changed at different intervals and as the acceleration rate changed. The third case analyzes the effects of the traffic signals and traffic volume. The results of these analyses showed that the change of the traffic state was closely related with the vehicle acceleration rate, traffic volume, and the traffic signal interval between intersections. These simulations confirmed that MATDYMO can represent the real traffic condition of the interrupted flow model. At the current stage of development, MATDYMO shows great promise and has significant implications on future traffic state forecasting research.
