  • Flexoelectricity is an interesting materials' property that is more touchable in small scales. This property beside the sandwich structures placed in the center of scientists' attention due to their extraordinary effects on the mechanical properties. Furthermore, in the passage of decades, more elaborated sandwich structures took into consideration results from using honeycomb core. This kind of structure, inspiring from honeycomb core, provides more stiffness to weight ratio, which plays a crucial role in different industries. In this paper, based on the Love-Kirchhoff's hypothesis, Hamilton's principle, modified couple stress theory and Fourier series analytical method, equations of motion for a sandwich plate containing a honeycomb core integrated by two face-sheets have derived and solved analytically. The equations of both face sheets have derived by flexoelectricity consideration. Moreover, it should be noticed that the whole structure rests on the visco-Pasternak foundation. Conducting current research provided an acceptable and throughout study based on flexoelectricity to address the effect of materials' characteristics, length-scale parameter, aspect, and thickness ratios and boundary conditions on the natural frequency of honeycomb sandwich plates. Also, based on the presented figures and tables, there is a close agreement between previous studies and recent work. Due to the high ratio of strength to weight, current model analyzing is capable of taking into account for different vehicles' manufacturing in a high range of industries.

  • The purpose of this study was to find a system and a progression principle in orchestral piece based on the outcome after comparatively analyzing the orchestral operation technique in "Battle for The Glory" out of the background music in the animation "Dragon Quest IV" by Koichi Sugiyama(1931~), who is a leading runner of Japan's animation music, based on functional parts daccord & Instrumentation Pattern, Rhythm Pattern, Voicing Pattern, and harmonic ratio by progression section devised by the writer. As a result, first, five themes in this music have specific instrumentation pattern, respectively. In a passage that is shown exposition, reprise, and representation in theme, the unity was emphasized by maintaining the same instrumentation pattern. On the contrary to this, a passage of being suggested new theme is being used the exchange method and addition & subtraction in musical instrument in order to strengthen diversity. Second, the voicing pattern is forming the vertical contrasting relationship of "thinness-thickness" on the whole. However, the diversity is being intensified that is changed into the structure of "thickness-thinness" in the third theme and of "thinness-thickness" that has two melodies in the fourth theme. Third, the rhythm pattern is forming the vertical contrasting relationship of "big-small" on the whole. However, the fifth theme is being given diversity with being changed into the structure of "small-big." Fourth, the harmony by progression section from the horizontal perspective is shown to be high in the proportion of unity in the section of being repeated and represented the theme and to be high in the proportion of diversity in the section of being suggested new theme. In this study, the balanced orchestral operation technique through the operation technique, which was used in this work, is what extracts the relationship of diverse proportions in the horizontal progression section based on the technique of vertical perspective. In this aspect, this analytical study is desired to be positioned as a new paradigm in establishing a theoretical system and an educational method in orchestration.

  • The Hong Kong issue covered in the study refers to the problems caused by the various measures and policies taken by the Chinese government since Hong Kong's return to China on July 1, 1997, and the resistance and resistance shown by the Hong Kong people. Since Hong Kong's return The Chinese government carried out a policy of strengthening direct control over Hong Kong, and on June 30, 2020, the Standing Committee of the National People's Congress of China passed the Hong Kong National Security Act. This study will focus on the impact of the Hong Kong issue on Cross-Strait Relations. Through this, we will take a look at the application of the "one-country, two-system" policy, Taiwan and China's Unification Issues and the democratization of Hong Kong. This study predicts that after the passage of the "Hong kong National security law," the principle of "one-country, two-system" that China tried to apply to unification with Taiwan will be put into a big test, and that Cross-Strait Relations and U.S.-China relations will deteriorate. Tension will quickly arise around Northeast Asia in the future, and we should also analyze and prepare for it in various ways.

  • The purpose of this study is to develop a new architectural language and design strategies that would anticipate and incorporate new historical situations and new paradigms to understand the world. It consists of four sections as follows: First, it presents a new interpretation of space, human body, and movement that we find in modern art and tries to combine that new artistic insight with environmental design to provide a theoretical basis for performance-event architecture. Second, it conceives of architectural environment as a combination of space, movement, and probabilistic situations rather than a mere conglomeration of material. It also perceives the environment as a stage for performance and the act of designing as a performance. Third, in this context, man is conceived of as an organic system that responds to, interacts with, and adapts himself to his environment through self-regulation. By the same token, architecture should be a dynamic system that undergoes a constant transformation in its attempt to accommodate human actions and behaviors as he copes with the contemporary philosophy characterized by the principle of uncertainty, fast-changing society, and the new developments in technology. Fourth, the relativistic and organic view-point that constitutes the background for all this is radically different from the causalistic and mechanistic view that characterized the forms and functions of modernistic design. The present study places a great emphases on dematerialistic conception of environment and puts forth a disprogramming method that would accommodate interchangeability in the passage of time and the intertextuality of form and function. In the event, performance-event architecture is a strategy based on the systems world-view that would enable the recovery of man's autonomy and the reconception of his environment as an object of art.

  • The script of the Fellowship of Daesoon Truth, 『Jeongyeong』 consists of seven sectors and 17 chapters. The seven sectors include 「Life of Sangje」, 「Reordering of the Universe」, 「Passing on of Teaching」, 「Law of Teaching」, 「Wisdom」, 「Cure of the Sick」, and 「Foreseeing」. The chapter 「Reordering of the Universe」 has the most records about Sangje, while the 「Law of Teaching」 has the most variety of materials in many passages about Sangje. This shows that the chapter 「Reordering of the Universe」 puts emphasis on the unique religious activities of Sangje and 「Law of Teaching」 is important for its edifying elements. "Law of teaching" is 敎法(Gyobeop) in Chinese character. 敎 means "teaching" and 法 "laws". What is law? A law becomes the rules for maintaining order of a society. In the view of religion, the law is ethical rules set by Kang Jeungsan to keep an order in the world. The first and second chapters of 「Law of Teaching」 have writings on 1. What Sangje said in person to the disciples, 2. The teachings Sangje gave to the disciples in certain occasions, 3. Reality of the society in late Joseon Dynasty, 4. Teachings related to the historical figures and old stories, and 5. Literatures. The third chapter has two special types of writing, which is about Taoism myths and statements written only in Chinese characters. In 『Daesoon Jeongyeong Volume 6』, the chapter 「Words of Law」 has more contents on edification for disciples, Cheok and resolving grudges with more detailed expression of woman resolving their piled up grudges. This chapter also has writings about discriminating old evil customs of Confucianism, emphasizing virtue and act of reciprocating for offered graces while training of one's mind and working on one's daily practice (shown in Sangje's saying about certain historical figures, quoting the Song of Suwun, statements in Chinese characters), Sangje's opinion about Japan, China, ancestral beings, eating raw foods, Byeokgok and others. In comparison with 「Words of Law」 in 『Daesoon Jeongyeong Volume 6』, which was issued in 1965 as the previous generation literature, 「Law of Teaching」 in 『Jeongyeong』 has many additional statements made to existing passages. Also, some passages were combined of two previous passages, some words were corrected, and in some passages, additional statements were made about the same person mentioned in another passage. And some passages were dropped. For the contents, 『Jeongyeong』 has additional statements about spiritual training of one's mind and practicing the teaching in daily lives, which indicates that 『Jeongyeong』 is focusing more on actual daily practice and the idea of overcoming hardships during the practice and realizing the principle of Resolution of all grudges.

  • This paper was carried out to bring the researches on Cultivation Practice of Daesoonjinrihoe which have been at a standstill after analyzing the directions of studies on Cultivation Practice and diagnosing its problems, in addition to that, the paper was also conducted in a way of discussing the research directions in the future. This work enables scholars who have interests in Daesoon Thoughts to easily comprehend over the length and breadth of Cultivation Practice of Daesoonjinrihoe as well as help them understand what level of researches regarding Cultivation Practice has been demanded. Furthermore, this paper will be a step-stone for scholars to ponder how and on what perspective they approach a wide variety of studies on Daesoon Thoughts. The problems reflected on the previous researches on Cultivation Practice are summarized as follows: first, except a few researches in general, problem recognition, research target, style, method, and content are not diverged from the frame defined by Jang Byeong-Gil, who set it up in Daesoon Religion and Thought (Daesoon Jonggyo Sasang) in 1989. Proliferating overlapped researches without developing problem awareness is of great concern. And such researching climate has gradually set in. Secondly, there are numerous researches intending to reveal the researcher's forceful attitude implying faith. Thirdly, most of the previous researches neglect to focus on defining the range of researches. Fourthly, when defining concepts, more thorough insight is needed. Lastly, the researches on analysing symbols and attempting signification analysis are relatively few, only to find many errors. To solve these problems, this paper suggests to develop theories which back up Cultivation Practice by researching on the fields of theory of mind-nature(心性), theory of mind-qi(心氣), theory of pain, Religious Ethics, viewpoint of God/gods, and psychology. Secondly, all the symbols and meanings of elements shown in Cultivation Practice need analyzing more elaborately sophisticatedly and more in-depth. In order to fulfil this goal, by adapting the recent trends of historical studies, it is essential to attempt to engraft Cultivation Practice of Daesoonjinrihoe on cultural phenomena, to analyze thick layers of meanings beneath its surface, to interpret differently, utilizing various perspectives such as focusing on the gender problems, and to extract true meanings out of Cultivation Practice by analyzing everyday events which can occur in real cultivation practices. Thirdly, the terms and concepts regarding Cultivation Practice base the principle themselves. Fourthly, by utilizing methodology of comparative studies on religions, the comparative researches on cultivation practice of different religious traditions are also needed. Lastly, the history of aspects on Cultivation Practice such as transition of mantras, processes which have been conducted through proprieties of prayer and training should be collected and classified. In this context, this work is very important since it helps understand the aspects of transition of originality and characteristics in Cultivation Practice of Daesoonjinrihoe according to passage of time.
