The degree of relative similarity between 2D patterns is obtained using Open-Ball Scheme. Open-Ball Scheme employs a method of transforming the geometrical information on 3D objects or 2D patterns into the features to measure the relative similarity for object(patten) recognition, with invariance on scale, rotation, and translation. The feature of an object is used to obtain the relative similarity and mapped into [0, 1] the interval of real line. For decades, Moment-Invariant Method has been used as one of the excellent methods for pattern classification and object recognition. Open-Ball Scheme uses the geometrical structure of patterns while Moment Invariant Method uses the statistical characteristics. Open-Ball Scheme is compared to Moment Invariant Method with respect to the way that it interprets two-dimensional patten classification, especially the paradigms are compared by the degree of closeness to human's intuitive understanding. Finally the effectiveness of the proposed Open-Ball Scheme is illustrated through simulations.

Pneumatic cushioning cylinders are commonly employed for vibration and shock control. A mathematical simulation model of a double acting pneumatic cushioning cylinder designed to absorb shock loads is presented which is based on the following assumptions; ideal equation of state isentropic flow through a port conservation of mass polytropic thermodynamics single degree of freedom piston dynamics and energy equivalent linear damping. These differential equation can be solved through numerical integration using the fourth order Runge-Kutta method. An experimental study was conducted to validate the results obtained by the numerical integra-tion technique. Simulated results show good agreement with experimental data. The computer simulation model presented here has been extremely useful not only in understanding the has been extremely useful not only in understanding the basic cushioning but also in evaluating different designs.

Due to the spread of COVID-19, the online lecture has become more prevalent. However, it was found that a lot of students and professors are experiencing lack of communication. This study is therefore designed to improve interactive communication between professors and students in real-time online lectures. To do so, we explore deep learning approaches for automatic recognition of students' facial expressions and classification of their understanding into 3 classes (Understand / Neutral / Not Understand). We use 'BlazeFace' model for face detection and 'ResNet-GRU' model for facial expression recognition (FER). We name this entire process 'Degree of Understanding (DoU)' algorithm. DoU algorithm can analyze a multitude of students collectively and present the result in visualized statistics. To our knowledge, this study has great significance in that this is the first study offers the statistics of understanding in lectures using FER. As a result, the algorithm achieved rapid speed of 0.098sec/frame with high accuracy of 94.3% in CPU environment, demonstrating the potential to be applied to real-time online lectures. DoU Algorithm can be extended to various fields where facial expressions play important roles in communications such as interactions with hearing impaired people.

The purpose of the study is to analyze the impact of storytelling factor, technical factor and exhibition environment factor on the degree of satisfaction, degree of immersion and immersion types in and . Our findings show that the degree of satisfaction not only has a significant correlation with the degree of immersion, but also influences on the holding power and behavioral intention. According to the results of correlation analyses, three factors have an impact on the degree of satisfaction and immersion. Immersion factors influence negatively on Focused Attention and Heightened Enjoyment, however, the factors effect positively on Temporal Dissociation and Curiosity. As the influence of immersiveness on the degree of satisfaction and immersion, and immersion types have been verified, this study offers a fresh understanding of the importance of immersion factors as evaluation criteria for digital exhibitions.

Graduate education in general means nurturing scholars who are capable of research that adds to the 'body of knowledge' and educators in the higher education system. Therefore 'discovering' new knowledge has always been a major role of graduate schools. However, interior design is a special field that 'application' can also produce new knowledge and therefore a wider understanding of scholarship is needed especially in the graduate level education. The purpose of this paper is to understand Interior Design graduate education system in the United States in order to develop issues that need to be discusses and addressed in Korea. Therefore, this paper first examines meanings of graduate degrees in general and current situation of Interior degrees offered in Korea. Then investigates the different types of graduate degrees in the U.S. such as post-professional degrees, first-professional degrees, and differences in general degree(M.A., M.S.) and professional degrees (M.F.A., M.I.D.). The researcher has used websites of each school and information lists of degrees offered by KIID and IDEC that serves as the main educators council in each countries. The characteristics of graduate degrees in America can be described as a structured system based on variety, flexibility, and distinction. For instance, M.F.A means a professional degree that is focused on building theory based project abilities, longer period to study but counted as a terminal in the field. However, in Korea even though the title of the degrees may differ there is not much difference shown in the educational contents. Therefore issues such as developing a more universal and international degree system, flexible and selective educational road-map, mutual understanding and unified system between various organizations for better graduate education system are proposed. Moreover, hope to start a discourse on defining scholarship and professionalism in the field of Interior Design.

The objectives of this study were: a) to measure the satisfaction of who volunteered in the activity, and b) to identify factors related to their satisfaction from the activities, and c) to provide policy implications to improve their satisfaction. This study was based on a literature review and empirical analyses. The empirical analyses have been completed through individual interviews with community residents who volunteer the NGO activities in the Korean Federation for Environmental Movement. The major findings from empirical analysis were as follows: As a result of correlation analysis, nine variables affecting the degree of their satisfaction were "activity time", "sex", "support of family and friends", "understanding of environmental NGO activities and fields of environmental NGO activities", "contact points for the activities", "income and vocation". As a result of multiple regression analysis, the five variables affecting the degree of their satisfaction were "understanding of the NGO activities", "income", "support of family", "marital status", "activity period" and these five variables explained 49.1% of the degree of their satisfaction. Based on the empirical findings, the following suggestions could be offered for the environmental NGO activities. 1) Environmental NGOs should offer resident-friendly programs which may help the residents participate in the NGO activities, so the volunteers can participate in the activities with their family, friends, and neighbors. 2) Environmental NGOs should provide appropriate information and educational supports to community residents, which might facilitate them to have a sound understanding of the NGO activities. And the environmental NGOs should provide diverse activity programs to facilitate participation and to formulate eligible management system for the activities. 3) To enhance the satisfaction of participation, environmental action programs should be organized and conducted through a careful consideration of the status of the community, the characteristics of residents, and so on. To provide better contact points, environmental NGOs should cooperate with religious organizations in communities, social groups, media and so on.

Allopathic medicine has had a lot of limits though it has maintained the status of mainstream medicine, therefore these days there has been a growing interests in traditional medicine of East Asia. According to this trend, the integration between allopathic medicine and traditional medicine has become a hot issue and the need of mutual understanding on their physiology and pathology increases. However, understanding of traditional medical theory based on ying-yang, five phases, viscera and bowels is still difficult to be accepted to allopathic medical fields. Therefore, this research tried to investigate the similarity and differences of the structures between five viscera and organs. As a result, this research found that the investigation and understanding on viscera in traditional medicine or organs in allopathic medicine has in common in some degree. However, the integration and comparison between two medicines should be done cautiously because there still are the basal different points of understanding of human structure and function.
