The functional requirements standards for electronic records management systems which have been published recently describe the specifications very precisely including not only core functions of records management but also the function of system management and optional modules. The fact that these functional requirements standards seem to be similar to each other in terms of the content of functions described in the standards is linked to the global standardization trends in the practical area of electronic records. In addition, these functional requirements standards which have been built upon with collaboration of archivists from many national archives, IT specialists, consultants and records management applications vendors result in not only obtaining high quality but also establishing the condition that the standards could be the certificate criteria easily. Though there might be a lot of different ways and approaches to benchmark the functional requirements standards developed from advanced electronic records management practice, this paper is showing the possibility and meaningful business cases of gaining useful practical ideas learned from imaging electronic records management practices related to the functional requirements standards. The business cases are explored central functions of records management and the intellectual control of the records such as classification scheme or disposal schedules. The first example is related to the classification scheme. Should the records classification be fixed at same number of level? Should a record item be filed only at the last node of classification scheme? The second example addresses a precise disposition schedule which is able to impose the event-driven chronological retention period to records and which could be operated using a inheritance concept between the parent nodes and child nodes in classification scheme. The third example shows the usage of the function which holds or freeze and release the records required to keep as evidence to comply with compliance like e-Discovery or the risk management of organizations under the premise that the records management should be the basis for the legal compliance. The last case shows some cases for bulk batch operation required if the records manager can use the ERMS as their useful tool. It is needed that the records managers are able to understand and interpret the specifications of functional requirements standards for ERMS in the practical view point, and to review the standards and extract required specifications for upgrading their own ERMS. The National Archives of Korea should provide various stakeholders with a sound basis for them to implement effective and efficient electronic records management practices through expanding the usage scope of the functional requirements standard for ERMS and making the common understanding about its implications.

"Women's Nong-ak (農樂, Traditional Korean music performed by farmers)" was born together with "Maiden group." This study focuses on the reason why women appeared as principal agents of Nong-ak which was almost exclusive to men previously and especially, on the appearance of women Nong-ak Artists who was previously worked in Traditional Drama Troupe. This study empirically deals with details of activities of Maiden's (娘子) Nong-ak troupes and Girls' (少女) Nong-ak troupes through newspaper articles. Women Nong-ak Artists enjoyed popularity with their peculiar attractions. Participating in Nong-ak contests and collecting money for their performances, women Nong-ak Artists learned their skills form masters of Woodo Nong-ak and attracted attention with their colorful costumes. Women of Nong-ak circle especially saw through the trend of the time, expanded their arena of activities and exercised flexibility and ability to react quickly to changing situations while mixing with various genres. In particular, young girls were mobilized to show value and marketability of Korean culture as cultural medium who decorated "Pure Nong-ak art stage." They were no different from "Pretty dolls dancing like angels" who could not purse their interest and economic benefit or incite political cause and their patrons were domestic and overseas political figures. Women artists, who put Nong-ak on the stage in the name of Maiden's (娘子) Nong-ak troupes and Girls' (少女) Nong-ak after the liberation from Japanese colonial rule, contributed to expansion of market base. Women Nong-ak artists, who dominated a century in such troupes as Sadangpae, Hyuprulsa, Maiden's (娘子) Nong-ak troupes, Girls' (少女) Nong-ak troupes and Women Nong-ak troupes, were the very heroines who overturned the conventions of "male predominance (男尊女卑)" which filled Nong-ak arena and cultivated a new tradition of Nong-ak culture.

In this article, the women as the subject of the family management in the 19th century cataclysm, In particular, I tried to reconstruct the specific life course of a woman who has a status as a jongbu(종부) in the Korean language through the Hangul letter. The Haenam Yoon's the 8th jongbu(종부) Gwangju Lee attempted to find her own unique identity, not the male-centered social order she had learned. Because she had to live a life outside the traditional environment of traditional society because her husband died at the beginning of her marriage. She perceived herself as an independent subject that she had to find and maintain. When Gwangju Lee married and came to the family of Haenam Yun, the economic power of jong-ga(종가) was much inclined. This economic difficulty was caused by the conflict with the slaves and the decrease of tallage(地代) to the change of the slavery system which was the social flow at that time. And uncles of her husband's intervention made the economic situation of the family more difficult. She established her position as a jongbu(종부) and used the right of Adoption option(입후권) of the jongbu(종부) to establish the impoverished family. She chose adoption from distant relatives who were not children of her husband's uncles. Therefore, I was free from her husband uncle's interests. She also believed that it was most important to take control of the economic interests of her family in order to secure her authority as a jongbu(종부). She believed that she had to exercise her economic rights in order to bring slave labor, which is the most important means of sustaining the domestic economy at the time, In the absence of her husband, she established her family in the social upheaval of the nineteenth century, and took her place as a master of a family, not just a family name.

Stock market investors are generally split into foreign investors, institutional investors, and individual investors. Compared to individual investor groups, professional investor groups such as foreign investors have an advantage in information and financial power and, as a result, foreign investors are known to show good investment performance among market participants. The purpose of this study is to propose an investment strategy that combines investor-specific transaction information and machine learning, and to analyze the portfolio investment performance of the proposed model using actual stock price and investor-specific transaction data. The Korea Exchange offers daily information on the volume of purchase and sale of each investor to securities firms. We developed a data collection program in C# programming language using an API provided by Daishin Securities Cybosplus, and collected 151 out of 200 KOSPI stocks with daily opening price, closing price and investor-specific net purchase data from January 2, 2007 to July 31, 2017. The self-organizing map model is an artificial neural network that performs clustering by unsupervised learning and has been introduced by Teuvo Kohonen since 1984. We implement competition among intra-surface artificial neurons, and all connections are non-recursive artificial neural networks that go from bottom to top. It can also be expanded to multiple layers, although many fault layers are commonly used. Linear functions are used by active functions of artificial nerve cells, and learning rules use Instar rules as well as general competitive learning. The core of the backpropagation model is the model that performs classification by supervised learning as an artificial neural network. We grouped and transformed investor-specific transaction volume data to learn backpropagation models through the self-organizing map model of artificial neural networks. As a result of the estimation of verification data through training, the portfolios were rebalanced monthly. For performance analysis, a passive portfolio was designated and the KOSPI 200 and KOSPI index returns for proxies on market returns were also obtained. Performance analysis was conducted using the equally-weighted portfolio return, compound interest rate, annual return, Maximum Draw Down, standard deviation, and Sharpe Ratio. Buy and hold returns of the top 10 market capitalization stocks are designated as a benchmark. Buy and hold strategy is the best strategy under the efficient market hypothesis. The prediction rate of learning data using backpropagation model was significantly high at 96.61%, while the prediction rate of verification data was also relatively high in the results of the 57.1% verification data. The performance evaluation of self-organizing map grouping can be determined as a result of a backpropagation model. This is because if the grouping results of the self-organizing map model had been poor, the learning results of the backpropagation model would have been poor. In this way, the performance assessment of machine learning is judged to be better learned than previous studies. Our portfolio doubled the return on the benchmark and performed better than the market returns on the KOSPI and KOSPI 200 indexes. In contrast to the benchmark, the MDD and standard deviation for portfolio risk indicators also showed better results. The Sharpe Ratio performed higher than benchmarks and stock market indexes. Through this, we presented the direction of portfolio composition program using machine learning and investor-specific transaction information and showed that it can be used to develop programs for real stock investment. The return is the result of monthly portfolio composition and asset rebalancing to the same proportion. Better outcomes are predicted when forming a monthly portfolio if the system is enforced by rebalancing the suggested stocks continuously without selling and re-buying it. Therefore, real transactions appear to be relevant.

Education is one of the priority sectors specified in Tanzania, and it has committed to provide 11 years of compulsory free basic education for all from pre-primary to lower secondary level. Despite the Government's efforts to provide free basic education to all children, there are 2.0 million (23.2 per cent) out of 8.5 million children at the primary school age of 7-13, who are out of school in Tanzania. The ICT class should be offered as a regular class in all secondary schools in Tanzania, recommended by the ministry of education. However, many schools are struggling to implement this mandate. Most of schools offer the ICT class with theory without any real hardware. Some schools were given with computers but they were not maintained for operation. There is a huge task to make ICT education universal. Main issues include: remoteness (off-grid area), lack of ICT teachers, lack of resources such as hardware, infrastructure, and lack of practical lessons or projects to be used at schools. An innovative blended ICT/STEM education program is being conducted not only for Tanzanian public and private/international schools, but also for out-of-school adolescents through institutions, NGO centers, home visits and at the E3 Empower academy center. For effective STEM education to take place and remain sustainable, more practical curriculum, and close-up teacher support need to be accompanied concurrently. Practical, project-based simple coding lessons have been developed and employed that students experience true learning. The effectiveness of the curriculum has been demonstrated in various project centers, and it showed that students are showing new interests in exploring new discovery, even though this was a totally new area for them. It has been designed for an easy replication, thus students who learned can repeat the lessons themselves to other students. The ultimate purpose of this project is to have IT education offered as universally as possible throughout the whole Tanzania. Quality education for all children is a key for better future for all. Previously it was hoped that education with discipline will improve the active learning. But now more than ever, we believe that children have the ability to learn on their own with given proper STEM education tools, guidelines and environment. This gives promising hope to all of us, including those in the developing countries.

As interest in private records began to develop in the research of archivists, discussions began about the value of private records and how to collect and manage private records from the standpoint of archivists. After that, the conceptual discussion on community archives, from the point of view of the community, collecting and preserving their own records, and the democratization of records and the sovereignty of records are discussed. As a result of this trend, maeul making projects were started in each region, and citizen archivists appeared who do archives activities. and research on the role and system of public institutions to support them and community archives. Recently, as research on regional record activities has begun, the current status of education and activities in each region is being announced. in addition archives education programs are being actively conducted nationwide to train citizen archivists. The purpose of this thesis is to find out their identity of their, in order to cultivate sustainable citizen archivists and to suggest the direction the citizen archivists training program should pursue. First, we consider that the educational goal of citizen archivists training program is to train citizen archivists who practice the knowledge learned through education, and examine the identity of 'citizen archivist', the goal of training education. In this study, local archivists are regarded as local members who engage in archiving activities based on their locality, and they are judged to be the main actors and core beings in building community archives. Also the activities of citizen archivists are viewed as active and subjective beings that realize 'Archival autonomy' by implementing 'Archival autonomy'. In addition, it analyzes the cases of researchable citizen archivist training programs in Korea that were conducted to foster local archivists and examines the current situation. Finally, the direction of citizen archivists training program for cultivating citizen archivists is presented. In this paper, I think that the citizen archivists training program should be designed as a curriculum to parctice the education goal, not as public program.

Recently, as word embedding has shown excellent performance in various tasks of deep learning-based natural language processing, researches on the advancement and application of word, sentence, and document embedding are being actively conducted. Among them, cross-language transfer, which enables semantic exchange between different languages, is growing simultaneously with the development of embedding models. Academia's interests in vector alignment are growing with the expectation that it can be applied to various embedding-based analysis. In particular, vector alignment is expected to be applied to mapping between specialized domains and generalized domains. In other words, it is expected that it will be possible to map the vocabulary of specialized fields such as R&D, medicine, and law into the space of the pre-trained language model learned with huge volume of general-purpose documents, or provide a clue for mapping vocabulary between mutually different specialized fields. However, since linear-based vector alignment which has been mainly studied in academia basically assumes statistical linearity, it tends to simplify the vector space. This essentially assumes that different types of vector spaces are geometrically similar, which yields a limitation that it causes inevitable distortion in the alignment process. To overcome this limitation, we propose a deep learning-based vector alignment methodology that effectively learns the nonlinearity of data. The proposed methodology consists of sequential learning of a skip-connected autoencoder and a regression model to align the specialized word embedding expressed in each space to the general embedding space. Finally, through the inference of the two trained models, the specialized vocabulary can be aligned in the general space. To verify the performance of the proposed methodology, an experiment was performed on a total of 77,578 documents in the field of 'health care' among national R&D tasks performed from 2011 to 2020. As a result, it was confirmed that the proposed methodology showed superior performance in terms of cosine similarity compared to the existing linear vector alignment.

This study aims to investigate and analyze the perception of communication capability which is one of the sub-competencies of NCS vocational substructure basic competence, and then seek the direction of prospective courses. To do this, the researcher conducts a non-face-to-face survey by creating five questions under the following five categories: The importance and necessity of communicative competence, students and educators of communicative competence classes, contents and methods of curriculum and teaching and learning, communicative competence and writing skills and operation of extracurricular programs. This researcher has been teaching basic education even before the communication skills curriculum was created in college, now, in a situation where communication skills have become selective education, it is intended to grasp the perception of college students about communication skills for first graders. This study attempted to analyze the survey area in more depth through group FGI after conducting an online survey by dividing it into several items. As a result, students felt that communication skills became motktkre important through COVID-19. Among the bottom five communication skills, speaking skills were found to be the most important, reading ability was recognized as the least important. On the other hand, there was a strong hope to know about the level of communication ability, type of communication, and method of communication about oneself. In addition, they recognized that communication skills should be learned in their first year of college, and hoped to be operated at all times as a non-disciplinary program. In particular, in the bottom five areas of communication skills, the expectations and actual hopes for speaking skills were the highest compared to the rest, and in terms of teaching and learning methods, they wanted to improve their skills through feedback and practice rather than theory. These research results have great implications for setting the direction of operation of classes, such as the content and method of classes in communication skills, in the future.

The purpose of this article is to understand the characteristics and meanings of the Hwanghae-do Gutchum, or shamanic ritual dance. First, the characteristics of the Hwanghae-do Gutchum are summarized as follows. The regular dances that appear in all pieces of Gutgeori or the tune of Gut of the Hwanghae-do Gutchum feature Geosangchum, followed by domu and heojeonmu in the sequential order. The accompaniment rhythms are Geosang rhythm, Chum rhythm, and Yeonpung rhythm. The dance featuring mugu, or shaman implements held on shaman's hand as part of the Hwanghae-do Gutchum, which symbolizes the characteristics of deities, is the same as domu aligned with the dance rhythm and the whirling dance aligned with the Yeonpung rhythm. The name of mugu, mubok (shaman clothing) and/or deities may be used as the name of Gutchum but there is no originality of Gutchum. The Beokgu Chum and Samhyeon Chum as part of the Hwanghae-do Gutchum use Beockgu Jangdan and Samhyeon Jangdan, which deserves to have their originality acknowledged. Hwanghae-do Gutchum is closely related to the rhythm. The harmony of janggu player and a female shaman is essential in practicing the Hwanghae-do Gut. If a janggu player fails to perform to properly support the gut practice of a female shaman, the shaman is not able to proceed with a smooth practice and causes confusion. On the other hand, if the gut performance of a female shaman fails to catch up with the performance of janggu, the gut becomes plain and simple at best. Janggu is the single most important element that determines the success or failure of the Hwanghae-do Gutchum. A female shaman takes the harmony and collaboration with a janggu player so seriously that she is willing to reschedule the practice of gut if its schedule does not match that of the janggu player. The Hwanghae-do Gutchum is largely dependent on gyeolrye. However, the difference between the chum and the rhythm caused by gyeolrye has disappeared due to the intangible cultural assets. That is, designating an intangible cultural asset has resulted in eliminating all distinctive characteristics of Hwanghae-do Gutchum. With the distinction of gyeolrye becoming vague, they have lost interest in the genealogy of gut they have learned. It is no longer gyeolrye but the intangible cultural property system that serves as an important factor to distinguish chums.

This thesis examines the play education method shown in the elementary school textbook 'Enjoy Play'. If the educational methods of the curriculum other than plays were presented in the order of 'Understanding play - Appreciation of Works - Creation of Works', the method of drama education is presented sequentially in the order of 'Understanding play - Creation of Works - Appreciation of Works' in the order of 'Understanding play - Artwork - Appreciation' have. Even if such a curriculum considers the study linked to the subject of 'Plays', students may not feel the 'burden' of 'creation', and by simplifying the understanding of 'spoken language', it is rather the characteristic of 'Korean language'. It may also make it difficult for students to feel the attraction. In addition, empathy through the conflict situation of the play or comparison with the actual conflict is mainly presented through the translation of foreign works or the expression of a fairy tale and fantastic world that is far from reality, so the burden of inferring the right life problems can be confirmed. Theatrical expressions and plays and plays learned through textbooks are partially different depending on the educational goals to be achieved. The result of this study is that the course of textbooks for elementary and upper grades may correspond to the problem of expressing 'Plays', but it is regrettable in leading students to think about ways to solve life problems in detail through 'Plays'. It is also necessary to emphasize the importance of expression that makes students realize how to express themselves autonomously in the way of expressing their feelings, but on the other hand, on the other hand, it is necessary to share empathy with feelings first, understand these feelings, Therefore, it was suggested that training to infer expressions and emotions by learning individual expressions through methods of expressing emotions and a process of educating students to voluntarily accept shared emotions are also necessary. Sharing and expressing emotional emotions through 'play', and participation through cooperation and division of labor through the process of performing.
