The mineralogical, physicochemical and thermal properties of the Myogi bentonite occurring in Japan were measured. A adsorption properties of U, Th, Ce and Eu ions on the Myogi bentonite were also investigated in different solution concentrations and pH conditions. The Myogi bentonite showed a strong alkaline character (pH 10.4), very high swelling, viscosity property and CEC, and a slow flocculation behavior due to the strong hydrophilic property. By the thermal analysis, the dehydroxylation of crystal water in bulk and clay fractions of the Myogi bentonite occur at $591^{\circ}C$ and $658^{\circ}C$, respectively, The adsorption experiments of ions such as U, Th, Ce and Eu were conducted for 0.2 g bentonites with 20mL solutions of various concentrations and different pH conditions with pH 3, 5, 7, 9, and 11. As a result, the Myogi bentonite showed excellent adsorption capacities for Ce, Th and Eu ions, whereas U ion showed very low adsorption capacity. Generally, Ce, Th and Eu ions showed the similar adsorption properties for the different concentrated solutions and pH conditions. These adsorption properties seem to be affected by the formation of various forms of chemical species and precipitation as well as ionic exchange reaction and surface adsorptions on smectite. Some associated zeolite minerals perhaps have some effects on the adsorption of U, Th, Ce and Eu on Myogi bentonite.

This thesis will observe and study the acting pattern and subtext of Ahn, Sung-kee who is known to be "The Nation's Actor" in South Korea's movie industry and currently has been on the screen with multiple different characters in about 120 films. He started his career as a child actor in Kim, Ki-young's movie at the age of five. Ahn is exceptional at communicating through solely on screen in terms of delivering characters' characteristics to audience with variety of characters. We provided some of the acting patterns he has shown in different roles of characters that he played such as in comedic, mellow and extraordinary acting. Following will be analysis on subtext of Professor Kim, Kyung-ho the role Ahn played in Jung, Ji-young's movie in terms of what type of factors was prepared and how it has delivered in each important scene. Generally, acting's basic skills and talents are similar between theater and movie. However, in movies, understanding of shots and preparation is needed. To deliver this well, a depth study of those characteristics such as expression method of subtext and continuous practice is necessary. Based on researches, we will talk about how important screen actors need to understand and prepare those characteristics when they act their roles and express the subtext of each character.

In this paper, we propose an optimized fuzzy controller based on Hierarchical Fair Competition-based Genetic Algorithms (HFCGA) for rotary inverted pendulum system. We adopt fuzzy controller to control the rotary inverted pendulum and the fuzzy rules of the fuzzy controller are designed based on the design methodology of Linear Quadratic Regulator (LQR) controller. Simple Genetic Algorithms (SGAs) is well known as optimization algorithms supporting search of a global character. There is a long list of successful usages of GAs reported in different application domains. It should be stressed, however, that GAs could still get trapped in a sub-optimal regions of the search space due to premature convergence. Accordingly the parallel genetic algorithm was developed to eliminate an effect of premature convergence. In particular, as one of diverse types of the PGA, HFCGA has emerged as an effective optimization mechanism for dealing with very large search space. We use HFCGA to optimize the parameter of the fuzzy controller. A comparative analysis between the simulation and the practical experiment demonstrates that the proposed HFCGA based fuzzy controller leads to superb performance in comparison with the conventional LQR controller as well as SGAs based fuzzy controller.

In that this study is a subject and character of risk, emerging security covers non-military areas in addition to traditional military security: environmental security, human security, resource security, and cyber security. The rise of these risks is not only changing the phenomenon of the new expansion of security areas, but also the expansion of the number and scope of security entities and the aspect of security world politics. These risks are transnational security issues at the global level in terms of their nature and extent of the damage, as well as multi-layered ones that affect local and personal security issues at the regional and national levels. In addition to national actors, non-state actors such as international organizations, multinational corporations, and global civil society, and furthermore, technology and social systems themselves are causing risks. Therefore, to solve the new security problem, it is necessary to establish a middle-level and complex governance mechanism that is sought at the regional and global levels beyond the fragmented dimension of the occurrence of new security issues that have been overlooked in the existing frame of perception, and to predict and find ways to respond to new security paradigms that have been identified in a broader sense.

The purpose of this study is about to consider the structure of dualistic recognition between "Gang-Ho"(ideal sanctuary) and real world in the "Songs of Fisherman" written by Lee Hyeon Bo. In order to do this job, I analized the arrangement of the contents and extract the exact in and outward meaning of elements and expressions; usage of them between lines of this Song. Based on these works, I tried to explain the confronted recognitions of the two worlds. At the first, about the arrangement and contents of this poem, It is consisted of 5 independent sub-poems and each of them are describing the value of fisherman's life(at the poem 가), separation from mundane world(나), satisfaction of fisherman's life(다), nature of "Gnag-Ho"(라), domiciliation in the place(마). It looks like that the writer intended to have the arrangement probability and likelihood connecting poems. Secondly, It contrast the nature of the "Gang-Ho" and real world. The sanctuary is a place of 'absence of worldly desire' and 'cordiality' that could afford one's harmonious life. On the other hand, the real world is a troublesome place which always conflicts political confrontations. For those reasons, the writer wants to satisfy with his living in "Gang-Ho" separating himself from the real world. Thirdly, The nature of "Gang-Ho" is 'absence of worldly desire' and 'cordiality' that one could be deserved his diligency becoming a part of the harmonious idealistic living place. Fourthly, on the character of story teller. Originally he is a incomer of "Gang-Ho" from real world. so that reason, he is showing dualism not to deny the loyalty oath to his king, while he intends to satisfy with the life in "Gang- Ho" separating himself from real world. As a gentry, at that time, the loyalty oath is inevitable one and that is found from writer's other works either. Fifthly, Characters of the different world recognition. The main reason of his intention to "Gang-Ho" roots on out of worldly confrontations, his separation from real world is on a joyous peaceful life just like in "Gang-Ho". this study believes the writer imply that 'absence of worldly desire' and 'cordiality' of "Gang-Ho", be a key role to resolve the confrontation of real world. Lee Hyeon Bo himself regards the two elements as a advisable attitude of life. At last, Seeing the writer's other work and literature's educational effect, this study defines that even if the poem outwardly express one's lyricism but inside it warns governors ruling attitude.

In this study, a program was developed and implemented for middle school students in the 'Healthy Family Relations' of the home economics based on design thinking process. The purpose was to investigate whether a significant difference is displayed in terms of empathy ability improvement among middle school students. For this purpose, a "Wise 'stay-at-home' life" program comprised of five class sessions was developed based on design thinking process. The program was implemented to male and female students in the second year of middle school, and students' empathy ability was examined by a pre- and post-test comparison. As a result, the developed program was found to have generated a significant improvement in cognitive empathy among middle school students. In addition, the students' satisfaction with the class was generally positive. In particular, many students mentioned that they were interested in activities such as 'empathizing through Instagram' and 'creating a sub-character'. However, there also was an opinion that the lesson activities were difficult to complete due to the lack of time and restrictions on cooperative activities due to COVID-19. In this research, we developed a program that can be used in both face-to-face and non-face-to-face situations in order to flexibly deal with situations where the learning environment changes due to COVID-19. And this research is significant particularly in that it confirmed that home economics have a positive influence on improving middle school students' empathy ability, particularly the cognitive factor of empathy.

Civil and commercial disputes can be resolved through alternative dispute settlement systems other than court proceedings. Among them, the arbitration procedure is a system that is clearly distinguished from the mediation procedure in which the dispute is terminated by agreement between the parties. The arbitration proceedings shall have the same effect as the result of the final judgment by the decision of a third-party arbitrator, and its essence is a judgment. The Korean Arbitration Association Studies was founded in December 1990 to recognize the importance of arbitration procedures and conduct specialized research on them, with professional research on 'arbitration procedures' continuing until today. Thus, the Korean Arbitration Association Studies is positioned as the only specialized research organization in the field of arbitration. In the case of the Korean Arbitration Association Studies, which is the only society in Korea related to arbitration and alternative dispute resolution, the members are mainly scholars majoring in trade and commerce and ones majoring in law. This situation reflects the distinctive character of the arbitration system because it is a matter of dispute procedures related to trade and commerce and many scholars who research trade and commerce need to prepare for possible disputes. In addition, the arbitration procedure is a dispute settlement procedure that substitutes for litigation because it has research value as a legal system. In particular, the 'Journal of Arbitration Studies' published by the Korean Arbitration Association plays a role in mediation, as well as mediation and presentation of research papers in the ADR field. This study analyzes the trends of mediation and ADR-related papers published in 'Journal of Arbitration Studies', an academic journal of the Korean Arbitration Association Studies, in four dimensions, celebrating the 30th anniversary of the Korean Arbitration Association Studies. First, this study examined which sub-themes are mainly studied among the various viewpoints of mediation through thematic analysis. Second, it looked at what methodology was used to study intervention at the methodological level. Third, it assessed what countries and regions had been mainly studied at the regional level. Fourth, in terms of content, what kind of research had been mainly conducted and what kind of research was relatively insufficient was investigated, analyzing the research results of the last 30 years and presenting a milestone for the research direction of 'Journal of Arbitration Studies' in the future.

This article examines celeactor as cultural contents focused on the multi-persona in a South Korean reality show program . The celeactor is a form of celebrity and part of a celetoid. Celebrity can be categorized by three forms: ascribed form, achieved form and attributed form. In attributed form, the celetoid suddenly becomes popular through the media. The celeactor is a subcategory of the celetoid. The celeactor is defined by a virtual character that exist in temporary or institutionalized traits of popular culture. The Korean celebrity culture presents Korean intellectual factors, spiritual aspects, tastes, moral virtue, power relationships and traditional hierarchy. In order to examine the features of the Korean celeactor in cultural contents, this article focuses on the multi-persona of celebrity in South Korean popular culture through fantasy, challenge and nostalgia. This article examines the multi-persona of celebrity represented in South Korean popular culture as a negotiated response to cultural identity deconstructed and reconstructed in performance. The research methodology is to analyze a South Korean television reality show program on MBC Hangout with Yoo that represents various sub-characters performed by Jae-suk Yoo, a South Korean comedian and host. As for theoretical underpinning, this exploration joins work on Erving Goffman's (1959) notion of self-presentation and Chris Rojek's (2001) celebrity studies.
