No one can deny the harsh reality that archival culture has not yet been permeated extensively into all the spheres of our society. Only fragmented records in fixed areas are in the custody of archives. Records to build a living memory for the history of our present are hard to find or remain minimal, if anywhere. Above all, there are few records in archives concerned with the everyday life of common people. No consideration has not been made about the reason for being of archives, not to mention of the strategy for establishing the archival culture. Accordingly, a paradigm shift is required for archives directly connected with the everyday life of common people. Archives of everyday life means one which interprets the behaviour and experiences of individuals(groups) within the context of society through categorizing everyday life of common people into the lesser fields. And archives of everyday life also means an organization or facility/place which documents the everyday life of individuals(groups), and collect, appraise, select and preserve the records from the view point of humanities for the reconstruction of history from the bottom. Archives of everyday life is an attempt to reconstruct memory and records on behaviour by and torment of the common people in the modern history of Korea, on the basis of which we can seek out the oppressive structure in the daily life of capitalism. Archival community should discuss about what is the meaning of records in the age of democracy unlike that of authoritarian era. We also need to have definite direction on the what kinds of records are to be created and appraised from the standpoint of common people. We are to make it possible to create Zeitgeist in the tackle of records and archives' content. on this kind of attempt archival community could make a practical contribution forward a more advanced democracy, resulted in having an opportunity to change the essence of archives.

Purpose: The purpose of this study was to compare the clinical outcomes of lithium disilicate ceramic pressed zirconia prostheses and monolithic zirconia prostheses and to investigate the complications after two years of follow-up in posterior edentulous site. Materials and methods: A total 17 patients (male: 12, female: 5) were treated with 60 posterior fixed implant-supported prostheses (LP. lithium disilicate ceramic pressed zirconia prostheses: n = 30, MZ. monolithic zirconia prostheses: n = 30). After 24-month, clinical examination of Implant survival rate, marginal bone resorption, probing depth, plaque index, bleeding index, calculus and complications were evaluated. Results: There were no failed implants and all implants were normal in function without mobility. Marginal bone resorption was lower in LP group than MZ group at 12-month (P < .05), and 12-month probing depth and calculus deposit in LP group were significantly higher than MZ group (P < .05). Most common complications in MZ were marginal bone resorptions more than 1.5.mm and 2 chipping occurred in LP group. Conclusion: Within the limitations of the present study, lithium disilicate ceramic pressed zirconia is considered as a predictable treatment option as much as monolithic zirconia in posterior fixed implant-supported prostheses.

Purpose: Normal education operation was difficult in the national disaster situation of Coronavirus Infection-19. Non-face-to-face education can be an alternative to face to face education, but it is not easy to provide the same level of education. In this study, the professor of disaster management field will identify problems that can occur in the overall operation and progress of non-face-to-face education and seek ways to improve non-face-to-face education. Method: Non-face-to-face real-time education was largely categorized into pre-class, in-class, post-class, and evaluation, and case studies were conducted through the professor's case studies. Result&Conclusion: The results of the survey are as follows: First, pre-class, it was worth considering providing a non-face-to-face educational place for professors, and the need for prior education on non-face-to-face educational equipment and systems was required. In addition, it seems necessary to make sure that education is operated smoothly by giving enough notice on classes and to make efforts to develop non-face-to-face education programs for practical class. Second, communication between professor and learner, and among learners can be an important factor in non-face-to-face mid classes. To this end, it is necessary to actively utilize debate-type classes to lead learners to participate in education and enhance the educational effect through constant interaction. Third, non-face-to-face post classes, policies on the protection of privacy due to video records should be prepared to protect the privacy of professors in advance, and copyright infringement on educational materials should also be considered. In addition, it is necessary to devise various methods for fair and objective evaluation. According to the results of the interview, in the contents, which are components of non-face-to-face education, non-face-to-face education requires detailed plans on the number of students, contents, and curriculum suitable for non-face-to-face education from the design of the education. In the system, it is necessary to give the professor enough time to fully learn and familiarize with the function of the program through pre-education on the program before the professor gives non-face-to-face classes, and to operate the helpdesk, which can thoroughly check the pre-examination before non-face-to-face education and quickly resolve the problem in case of a problem.

This study was conducted to determine the degree of reduction in the yield of sweetpotato subjected to different shading treatments according to the growing season of the typical viscous sweetpotato 'Hogammi' and the powdery sweetpotato 'Jinyulmi'. Shading was provided using commercially available shading nets (55% and 75% shading level), and the treatments were applied at the following stages of storage root growth: SFS: the storage root formation stage (planting-50^th day), SSS: the storage root swelling stage (50-90^th day), and SAS: the storage root actively swelling Stage (90-120^th day). The growth characteristics according to shading treatments during each growth period, the number of tubers obtained at harvest, and sugar contents were investigated. For both assessed cultivars, there was no significant difference between the control group and the 55% shading treated group with respect to the maximum quantum yield (Fv/Fm) of photosystem II under different shading treatments, whereas the 75% shading group showed slightly higher values than the control group. In both cultivars, the contents of chlorophyll a and b tended to increase in plants subjected to shading treatments compared with the control plants, particularly that of chlorophyll b. Compared with the control group, the chlorophyll b content of 'Hogammi' subjected to 55% and 75% shading increased by 47% and 41%, respectively, whereas that of 'Jinyulmi' increased by 39% and 34%, respectively. We also detected reductions in the dry weights of the above- and belowground parts of the two varieties in response to shading compared with the control, with the reduction in the dry weight of belowground parts being significant. Furthermore, in both varieties, the T/R rate tended to increase in response to shading treatment. Owing to the lack of sunlight, both cultivars tended to suppress the formation and enlargement of tuber roots. Consequently, post-harvest yield analysis revealed that under shading treatments, both cultivars were characterized by poor tuber root growth according to growing season, with the yield of 'Hogammi' showing a greater reduction compared with that of 'Jinyulmi'. In addition, we found that the higher shading level also significantly reduced yields. Compared with the storage root formation and storage root actively swelling stages, shading treatments during the storage root swelling stage significantly affected yield reduction in both varieties.

Purpose : The purpose of this study is to evaluate clinical applicability of Co-60 ViewRay treatment plan to increase the skin dose in case of high skin dose is required such as Malignant Fungating Wound By measuring the presence / absence of Bolus application and skin dose by the treatment device and comparing it Materials and Methods : Nine inner measuring points of 2.5 cm lattice arrangement and all 13 measuring points including upper and lower left and right measuring points touching the chest and skin were marked. After CT was taken, each treatment plan was formulated through Eclipse and ViewRay-TPS, and a Fixed beam-IMRT treatment plan was formulated so that the left chest V2Gy=95 % is delivered. Before measurement QED detector was calibrated and the QED detector was positioned at the 13 measurement points displayed on Phantom and surface dose of each treatment planner was measured using 5 mm Bolus application using True-beam and View-ray before and after, measure three times and compare each before applying 5 mm Bolus. Results : The surface dose of the Co-60 ViewRay and the linear accelerator appeared at $76.8%{\pm}5.2%$ vs. $67.3{\pm}%7.5%$ and the surface dose after application of 5 mm Bolus was $87.6%{\pm}8.9%$ vs. $80.3%{\pm}10.2%$ It was measured at 10.2 % (p<0.001). Conclusion : As a result of the surface dose measurement of each treatment instrument, Co-60 ViewRay confirmed that the surface dose reached 95.6 % of 6 MV Linac with conventional 5 mm bolus, despite not using Bolus (p<0.001). Also, by utilizing magnetic resonance images for each treatment, it is possible to observe the change in the treatment site without the problem of exposure, it is easy to formulate an adaptive treatment plan and it is easy to secure the skin dose, so the size In the case of Malignant Fungating Wound patients who need fast skin changes and need high skin doses, Co-60 ViewRay is considered to be more useful than linear accelerators.

We constructed a stand yield table for Chamaecyparis obtusa based on data from an actual forest. The previous stand yield table had a number of disadvantages because it was based on actual forest information. In the present study we used data from more than 200 sampling plots in a stand of Chamaecyparis obtusa. The analysis included theestimation, recovery and prediction of the distribution of values for diameter at breast height (DBH), and the result is a valuable process for the preparation ofstand yield tables. The DBH distribution model uses a Weibull function, and the site index (base age: 30 years), the standard for assessing forest productivity, was derived using the Chapman-Richards formula. Several estimation formulas for the preparation of the stand yield table were considered for the fitness index, and the optimal formula was chosen. The analysis shows that the site index is in the range of 10 to 18 in the Chamaecyparis obtusa stand. The estimated stand volume of each sample plot was found to have an accuracy of 62%. According to the residuals analysis, the stands showed even distribution around zero, which indicates that the results are useful in the field. Comparing the table constructed in this study to the existing stand yield table, we found that our table yielded comparatively higher values for growth. This is probably because the existing analysis data used a small amount of research data that did not properly reflect. We hope that the stand yield table of Chamaecyparis obtusa, a representative species of southern regions, will be widely used for forest management. As these forests stabilize and growth progresses, we plan to construct an additional yield table applicable to the production of developed stands.

The purpose of this paper is to clarify that the difference between past and present response to the same folktales relates to other cultural contexts. This is part of the research to explore the methodology of folktale education for intergenerational communication. This paper compares the reaction on a storytelling site from the past to with current college students' impressions. On the older site, the storyteller and audience sympathized with the characters of . Additionally, they were pleased with the conclusion that the characters would get a new family. However, university students thought that the characters of was incompetent. University students evaluated their success as depending on other people, accidentally obtained. Such a difference was closely related to the culture of the group intervening when understanding the folktale. In the past culture, empathy, interdependence, and unity were considered important values. Meanwhile, the new-generation culture emphasized the individual's free will and rights, diligence, and honesty. As a result, due to differences in cultural context, university students distorted , and communication with past generations was also broken. In this paper, we study the folktale education methodology that helps communication between generations. this paper proposes that It is more suitable to tile the story instead of for university students. That is because resembles the cultural context of university students. At the same time, it has the same problem as .

Crisis of trust in Korean society, especially south-south conflicts among Korean political circle, civil society and peoples on the issue of the Korean peninsula policy driven by south Korean government, have weakened the sustainable and consistent energy of the policy for peace and unification of Korea peninsula. At the moment of drastic change of south-north relation in Korean peninsula, National agreement as a foundation of sustainable peace and unification policy has very important meaning. Because of this, national contract of unification as a kind of social concertation, has been demanded. National contract for peace and unification is an unprecedented process for making unofficial legal norm because it authorize quasi-legislative binding force on the agreement which is concluded by the Korean political circle, civil society and peoples for the peace and unification of Korean peninsula. National contract for peace and unification includes 'agreed aim and principles' for peace, prosperity and unification as well as process and result. And National contract for peace and unification, also is characterized long duration of aim achievement and openness of participating subjects. In terms of law, it will be legitimate source for comprehensive modification of international and internal law. In addition, The nature of National contract for peace and unification, as a people's law, should be considered as soft law which has the power to realize its contents through the enactment of legislation and policy. In order to guarantee the establishment and effectiveness of National contract for peace and unification, the setting of organization is need to determine the range of representatives, who participate in the process of contract making, procedure of contract and to carry out the contract after the conclusion of National contract for peace and unification. For the reason, the Council of National Contract for Peace and Unification as a independent administrative government committee and 'Act on National Contract for Peace and Unification' is needed.

This study was inspired by the issue that the fundamentals of education have been overlooked, as today's smart education policies established in the knowledge-based information society of the 21st century have only focused on building digital environment and its efficiency. To carry out the study, the media education of Germany, which is equivalent of Korea's smart education, was analyzed to obtain implications for Korea's smart education. In Germany, the media education has been managed by the country ever since the information society has begun. Since 2009, the media education has become a requirement for all schools in every state. Thus, the current media education policy of each state has been analyzed, which revealed the following common characteristics. 1) The media education is closely linked to existing curriculum and education, rather than being conducted separately with different standards. 2) The media education is being conducted in a democratic manner by actively reflecting the exemplary cases of school teachers, rather than following the instructions and guidelines from the government. 3) The media education deals with the character and identity of young students, based on their basic understanding of information society, which are essential for a successful life in the upcoming society. Unlike the first and second implication linked to the method and procedure of media education policy, the third implication is the basic purpose of media education, which is also the key implication of this study. The media education policy of Germany, which is being conducted with its own educational philosophy, offers significant implications for Korea's smart education policy. In Korea, the education only revolves around device-based environment innovation or content development. It should be noted that the purpose of smart education is developing smart individuals who can bring better, happier, and more successful society - rather than establishing a smart environment. Therefore, the focus of discussion on Korea's smart education that revolves around environment, infrastructure, device utilization, and contents development should be changed to the character and identity of students, which are required in the future smart era. That's when 'human-based' educational revolution, instead of 'device-based' classroom revolution can begin.

I. Identity of Yeonsegeuk as total arts. The purpose of the thesis is to arrange the identy of Yeonsegeuk(Kino-Drama) which is theatre or film. The process of study is tried to discuss on the aethetic of Yeonsegeuk. II. Appearance of Yeonsegeuk and negative disputation of yeonsegeuk The first imported Yeonsegeuk from Japanese in Korea is made by the group of Mizuno Ganggetsu(水野觀月) on Oct. 16. 1915 at Pusan and also to run in Seoul at Hwanggeumgwan. The first of Korean Yeonsegeuk is by Kim, Dosan, a leader of Singeukjwa(theare group) on Oct. 27. 1919 at Danseongsa. Before the liberation of Korea from Japan all made korean Yeonsegeuk are 28 works. III. Dramatic form of Yeonsegeuk I study on the relation between Yeonsegeuik and Sinpageuik(new theatre of modern drama in 1920's). I find that Yeonsegeuik admitted the thechnics of the Sinpageuik and the contents. If We think that the theatre is synthetic art which genealize all arts, we can insist that the Yeonsegeuk is valued the total art as new performance to comply with film art to theatre. Conclusionly Yeonsegeuk is called 'Expanded Theatre' as the new performance which must be dicussed in the view of total art. VI. Discussion on the the aethetic of Yeonsegeuk When we compare the structure of film with the structure of theatre, we can't find a diffrent element between the structure of two art in art semiotic. But we find a fact that film art has special elements in mechanics character which are camera working and motage. These technics influence on the audience's mind. It is different point between Japan and Korean's Kino-drama and Germany's that is to admit the aethetic of total art or not. V. Yeonsegeuk as new performance During Korean modern times Kino-drama was first a kind of total art with stage and screen. But it is regretable that Kino-drama didn't have the background of theory which discourse on the comprehension of total art. As the result Kino-drama bring the confusion of argument that Kino-drama is total art or expanded theatre. This confusion will be disputed on film art as performing arts or future art as expanded film and total art.
