For a lack of books on tea ceremony, 'Dongdasong (東茶頌)' by Buddhist priest Choui occupies a prominent position. Along with 'Dabu (茶賦)' by Yi Mok (李穆: 1471~1498) and 'Gida (記茶)' by Yi Deok-ri (李德履: 1728~ ?), Dongdasong forms the three peaks of tea work. These books are all based on Tea Classic (茶經) by Ryukwoo (陸羽). Assuming that Tea Classic serves as introduction (起), Dabu is development (承), Gida for turn (轉) and Dongdasong for conclusion (結). Dongdasong is inextricable from Dasinjeon (茶神傳). Dasinjeon is the abstract of Jangwon's Darok (茶錄). The keyword of Dasinjeon is 'tea deity (茶神).' Extracting key concepts of Darok as his perspective, Choui established his own philosophy on tea ceremony. In the process of making into his philosophy, he reorganized the system by introducing the principle of 'subtle combination (妙合),' one of traditions in Korean thought, which is characterized by not separating spirit and material. It is 'subtle combination' that does not make a division between spirit and material, which are undeniably different things. Subtle combination is a relation of two things' being one and one thing's being two. Choui's philosophy on tea ceremony can be assessed as valuable inheritance from traditions of Korean thought.

This study aimed to make clear the education process, from antenatal training to early childhood education, of Joseon Royal Family. Centered on the successors to the throne and reviewed also the education of other Royal Family members, this study carried out comparative analysis on them. Antenatal training is pregnant woman's essential physical and mental attitude. It is indispensable to the health and good nature of unborn baby. Antenatal training had been based on the theory of Oriental medical science that fetus can sympathize what mother see and feel. Such theory, combined with Confucian self-culture theory, had taken very important position in Confucianism. Not to speak of Royal Family, noble family regarded antenatal training very essential as beginning of education and root of nature formation. For firstborn son and firstborn grandson, Boyangcheong (輔養廳, special nursery agency) was set up before their age became three, but not for other sons and grandsons of Royal Family. When firstborn son or firstborn grandson grew up to read letters, Ganghakcheong (講學廳) was set up for their early education. Other sons of king also learned in their early ages at Ganghakcheong while other grandsons of king learned at Gyohakcheong (敎學廳). Education courses were almost same between successors and non-successors but there were wide difference in the ranks of their tutors; firstborn son's tutor marked 2nd Jeong(正) class, firstborn grandson's tutor marked 2nd Jong(從) class and other royal sons' tutors were just 9th Jong(從) class.

Representation of destitution may be considered as an expression of a social desire toward forging a bond or solidarity with the impoverished. However, political and ethical demands of the solidarity force the formulaic framework structuring the form of representation to its limits. The thesis aims to examine the responses to such demands within the tradition of modernist literature that can be traced from Charles Baudelaire, Knut Hamsun to Franz Kafka and that somehow culminates with Samuel Beckett, and to analyze how the issue of destitution that weaves through Beckett's works criticizes and inherits such a heritage. Whereas destitution in 19th century Realism is structurally fixed and its potential for change is inherently excluded, for these writers, destitution is no longer the state of rigid reality in which any possibility is limited. It is destitution as an imperative that calls for exploitation of possibilities that can be recuperated from the impoverished condition of destitution. What these writers consistently resist against is destitution that leads to compensation and reward. Since occupying a superior position toward the other as the subject of description or sympathy can be seen as one form of profit or reward, they have persistently pursued absolute solitariness and austere conditions rather than prematurely simulating a sense of solidarity and community. The ultimate goal of destitution as an imperative is to pursue destitution in order to worsen it by identifying and then excluding and expending possessions and assets to a state of penury. This is a paradoxical process that opens up the realm of possibilities of destitution and redefines it as abundance and wealth. Destitution for Beckett as seen in the writers above is the objective of literature. But, what he focuses on is to amplify the shreds of economic world that still remain in a state of poverty and to reveal extreme poverty as a state of odd affluence and to transform it into a pursuit of accumulation and profit. One of his famous axioms, "less is more", contains the essence of such a paradoxical strategy. In a sense, such approach is a twist on the strategy that identifies and uses any remaining potential hidden in destitution as was pursued by other writers. It also expands on the imagination of the destitute described by Hamsun. But Hamsun and Beckett are diametrical opposites. Unlike Hamsun, Beckett does not link imagination with a sense of guilt. Imagination is not intended to overcome the destitute reality nor to culminate in artistic martyrdom as in the case of Kafka's hunger artist. The imagination of the impoverished in Beckett is simply a hilarious game and not an escape that ends in a sense of guilt. This game formulates a "rhetorical question" or derision at the ironical situation where the pursuit of hunger and art as the disinterestedness has been turned into symbolic capital. It is inherently a fundamental critique at the aestheticization of destitution that has been pursued by Modernism. Beckett's efforts at divulging falsehood inherent in non-profit acts such as charity, donation and hospitality are dissections of social fictions in which aestheticization of destitution remains a part of the whole.

Recent advances in mobile devices and development of various mobile applications dealing with private information of users made user authentication in mobile devices a very important issue. This paper presents a new user authentication method based on touch screen interfaces. This method uses for authentication the PIN digits as well as the exact locations the user touches to input these digits. Our method is fully compatible with the regular PIN entry method which uses numeric keypads, and it provides better usability than the behavioral biometric schemes because its PIN registration process is much simpler. According to our experiments, our method guarantees EERs of 12.8%, 8.3%, and 9.3% for 4-digit PINs, 6-digit PINs, and 11-digit cell phone numbers, respectively, under the extremely conservative assumption that all users have the same PIN digits and cell phone numbers. Thus we can guarantee much higher performance in identification functionality by applying this result to a more practical situation where every user uses distinct PIN and sell phone number. Finally, our method is far more secure than the regular PIN entry method, which is verified by our experiments where attackers are required to recover a PIN after observing the PIN entry processes of the regular PIN and our method under the same level of security parameters.

Cable-stayed bridges are infrastructure facilities of a highly public nature; therefore, it is essential to ensure operational safety and prompt response in the event of a collapse or damage caused by natural and social disasters. Among social disasters, impact accidents can occur in bridges when a vehicle collides with a pier or when crashes occur due to aircraft defects. In the case of offshore bridges, ship collisions will occur at the bottom of the pylon. In this research, a procedure to evaluate the structural behavior of a cable-stayed bridge for aircraft impact is suggested based on a numerical analysis approach, and the feasibility of the procedure is demonstrated by performing an example assessment. The suggested procedure includes 1) setting up suitable aircraft impact hazard scenarios, 2) structural modeling considering the complex behavior mechanisms of cable-stayed bridges, and 3) structural behavior evaluation of cable-stayed bridges using numerical impact simulation. It was observed that the scenario set in this study did not significantly affect the target bridge. However, if impact analysis is performed through various scenarios in the future, the load position and critical load level to cause serious damage to the bridge could be identified. The scenario-based assessment process employed in this study is expected to facilitate the evaluation of bridge structures under aircraft impact in both existing bridges and future designs.

This study examined the position and the characteristics of Korean writing textbooks in the rationales for writing education. Also, it explored the activities of writing knowledge formation based on the rationales in order to further propose some suggestions for the development of writing textbooks afterward. For this, it chose four Korean writing textbooks and presented the analyzed results through the processes consisting of material gathering, open coding, deep coding, expression and presentation as ones for the text qualitative analysis. First, it researched how the rationales such as formalism, cognitivism, and social constructivism were applied to and manifested in those textbooks. Furthermore, it examined how the language activities in the textbooks were shown from the four dimensions such as the knowledge of language structure, the process knowledge, the context knowledge, and the content knowledge; in particular, it focused on the content knowledge. It found out the results as follows. The rationales in structuring the chapters were not consistent with inner structures and contents. All the four writing knowledges were applied to each textbook; however, the emphasis and the proportion were different in each textbook. Also, it pointed out the textbook which contains diverse activities to be able to help the learners form the content knowledge and this sort of textbook is more effective from the perspective of social constructivism. Based on those results, it discussed several points which can be considered in the development and the selection of Korean writing textbooks later.

Building Ukraine as an independent, sovereign state requires the education of a citizen-patriot, able to live and work in a democracy, ensure the unity of Ukraine, feel constant responsibility for themselves, their people, country, seek to make a real contribution to the reform process. Modern modernization of the education system requires the search for new information and communication technologies that can ensure the formation of a citizen with an active civic position, which involves not only students mastering the rights and responsibilities of citizens, convincing them of the feasibility of democratic transformation of society, patriotic qualities and feelings, but also the identification of motivated civic actions. The pandemic and hostilities have led to significant changes in the field of education around the world, they have caused educational problems in Ukraine. At the beginning of the quarantine in the spring of 2020, all educational institutions in the emergency mode switched to distance learning. Intensive use of information and communication technologies in the life of modern society has led to a rethinking of the content of education and training of future professionals: the main role is played not so much by the information itself as the ability to work with it, critically comprehend and produce new knowledge; the main thing is not the amount of information, but its quality; information is needed for further practical application and transformation into knowledge, and the ability to work with information becomes one of the important competencies of the modern specialist in the new transformation of society: from information to the knowledge society. In this context, one of the main forms of training is distance learning, which is able to respond to the challenges of society. The main methodological positions that are taken into account in the construction of the structure and dynamics of the formation of civic responsibility of the individual during the use of information and communication technologies are highlighted. The structure of civil responsibility as a holistic system of information and communication technologies is outlined, which includes three subsystems that characterize the natural, social and systemic qualities of citizenship, interconnected hierarchically and synergistically.The constituent elements of the structural part of the model of civic culture of the individual are analyzed.

The purpose of this study is an empirical case study that focuses on bring about changes in clients through narrative therapy using scaffolding. Through this, the purpose was to find the preferred values and hopes of the future among the stories that the client's has lived in. As the research method, we proceed through unstructured interview and loose structures in qualitative research. On this premise, the counselor did not diagnose or explain the 'decentralized but influential' attitudes and problem. And there was no order in the conversation, and I didn't decide in advance how to react to it before the client made any expressions. This study has the following significance on a practical and academic level: First of all, counseling through scaffolding further enrich the curiosity, temperament, and wishes of the client. Second, the scaffolding provides a concrete picture of the relationship between a counselor and a client in narrative therapy. Third, the scaffolding made in therapeutic dialogue presents a 'learning tasks'. Fourth, counseling through scaffolding has an active meaning that it can develop the higher mental function of clients in charge. Finally, we presented an application of narrative therapy in Vygotsky's theory through analysis of empirical cases. Based on this information, this study did not simply intend to position the client as a research object in narrative therapy. It is meaningful that they have identified the factors necessary to become the subject of narrative therapy and the role of the counselor in the process. In addition, this study has implications in that it contributed to the expansion and substantialization of the research scope of narrative therapy in that it utilized the concept of scaffolding, which has not received much attention in the domestic research.

The Entry-Descent-Landing process of a lander involves many environmental and technical challenges. To solve these problems, recently, terrestrial relative navigation (TRN) technology has been essential for landers. TRN is a technology for estimating the position and attitude of a lander by comparing Inertial Measurement Unit (IMU) data and image data collected from a descending lander with pre-built reference data. In this paper, we present a method for generating descent dataset and extracting landmarks, which are key elements for developing TRN technologies to be used on Mars. The proposed method generates IMU data of a descending lander using a simulated Mars landing trajectory and generates descent images from high-resolution ortho-map and digital elevation map through a ray tracing technique. Landmark extraction is performed by an area-based extraction method due to the low-textured surfaces on Mars. In addition, search area reduction is carried out to improve matching accuracy and speed. The performance evaluation result for the descent dataset generation method showed that the proposed method can generate images that satisfy the imaging geometry. The performance evaluation result for the landmark extraction method showed that the proposed method ensures several meters of positioning accuracy while ensuring processing speed as fast as the feature-based methods.

In order to replace the sampling tensile test of products produced in the tab welding process, which is one of the automotive battery manufacturing processes, vision inspectors are currently being developed and used. However, the vision inspection has the problem of inspection position error and the cost of improving it. In order to solve these problems, there are recent cases of applying deep learning technology. As one such case, this paper tries to examine the usefulness of applying Faster R-CNN, one of the deep learning technologies, to existing product inspection. The images acquired through the existing vision inspection machine are used as training data and trained using the Faster R-CNN ResNet101 V1 1024x1024 model. The results of the conventional vision test and Faster R-CNN test are compared and analyzed based on the test standards of 0% non-detection and 10% over-detection. The non-detection rate is 34.5% in the conventional vision test and 0% in the Faster R-CNN test. The over-detection rate is 100% in the conventional vision test and 6.9% in Faster R-CNN. From these results, it is confirmed that deep learning technology is very useful for detecting welding error of lead tabs in automobile batteries.
