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.
Recently, distribution of record via web and coefficient of utilization are increase. so, Archival information service using website becomes essential part of record center. The main point of archival information service by website is making record information retrieval easy. It has need of matching user's request and representation of record resources correctly to making archival information retrieval easy. Archivist and record manager have used various information representation tools from taxonomy to recent thesaurus, still, the accuracy of information retrieval has not solved. This study constructed record retrieval system based on Topic Map by modeling record resources which focusing on description metadata of the records to improve this problem. The target user of the system is general web users and its range is limited to the president related sources in the National Archives Portal Service. The procedure is as follows; 1) Design an ontology model for archival information service based on topic map which focusing on description metadata of the records. 2) Buildpractical record retrieval system with topic map that received information source list, which extracted from the National Archives Portal Service, by editor. 3) Check and assess features of record retrieval system based on topic map through user interface. Through the practice, relevance navigation to other record sources by semantic inference of description metadata is confirmed. And also, records could be built up as knowledge with result of scattered archival sources.

This study was performed to predict change of forestland area in future to 2050 based on System Dynamics Model which is based on feedback loop by causal relationship. As forestland area change in the future depends on potential forestland conversion demands, each demand type of forestland conversion such as agricultural, industrial, public and residential/commercial use was modeled using annual GDP, population, number of household, household construction permission area (1981~2019). In results, all of conversion demands would have continuously decreased to 2050 while residential and commercial land would be reduced from 2034. Due to such shortage, eventually, total of forestland in South Korea would have decreased to 6.18 million ha when compared to current 6.29 million ha. Moreover, the forestland conversion to other use types must be occurred continuously in future because most of forestland is owned privately in South Korea. Such steady decrement of forestland area in future can contribute to the shortage of carbon sink and encumber achievement of national carbon-neutral goal to 2050. If forestland conversion would be occurred inevitably in future according to such change trends of all types, improved laws and polices related to forestland should be prepared for planned use and rational conservation in terms of whole territory management. Therefore, it is needed to offer sufficient incentive, such as tax reduction and payment of ecosystem service on excellent forestland protection and maintenance, to private owners for minimizing forestland conversion. Moreover, active afforestation policy and practice have to be implemented on idle land for reaching national goal 'Carbon Neutral to 2050' in South Korea.

BIM models allow building spaces to be instantiated and recognized as unique objects independently of model elements. These instantiated spaces provide the required semantics that can be leveraged for building code checking, energy analysis, and evacuation route analysis. However, theses spaces or rooms need to be designated manually, which in practice, lead to errors and omissions. Thus, most BIM models today does not guarantee the semantic integrity of space designations, limiting their potential applicability. Recent studies have explored ways to automate space allocation in BIM models using artificial intelligence algorithms, but they are limited in their scope and relatively low classification accuracy. This study explored the use of Graph Convolutional Networks, an algorithm exclusively tailored for graph data structures. The goal was to utilize not only geometry information but also the semantic relational data between spaces and elements in the BIM model. Results of the study confirmed that the accuracy was improved by about 8% compared to algorithms that only used geometric distinctions of the individual spaces.

This study was conducted to obtain basic materials to improve the teaching method of Home Economics by theoretically looking into the supplementary teaching materials or implements usable in teaching Costume History area. And based on these data, the types and the applications of the supplementary teaching materials or implements highschool owned were examined. The subjects of this study were 111 Home Economics and Housework curriculum highschool teachers who give a lecture in the country by using self-administered questionnaires. SAS program was used to calculate frequency, percentage, average, standard deviation, and $\chi$(sup)2-test analysis. The results of the study were as follows; 1. Most of the highschool teachers used the school expenses for experiments in preparing the supplementary teaching materials or implements. 2. Of the supplementary teaching materials and implements concerning Costume History, visual implements such as slides and pictures were the mostly owned. CD and audio implements as cassette-tapes were not used. 3. Most of the teachers recognized the importance of the audio-visual teaching materials and implements concerning Costume History. 4. Among the audio-visual materials and implements concerning Costume History by which can be made by school teachers of Home Economics and Housework curriculum, the mostly used one was ‘cutting pictorials from magazines and newspapers’, and the next were ‘orbital materials’, and ‘copy the pictorials’, and the least was ‘recording from the radio’. 5. Most of the annual expenses assigned to the department of Home Economics was used in cooking practice, and the least of the expenses was assigned in buying audio-visual teaching materials and implements. 6. Time assigned to the area of Home Economics was for the most part one or two hours per week, and among this, time assigned to the history of western costume and the history ok korean costume was for the most part five to eight hours. 7. The areas that the highschool teachers felt difficulties mostly during clothing and textiles curriculum were ‘textiles’and the next were ‘knitting’, ‘western costume history’, and ‘korean clothing construction’. 8. The difficulties the highschool teachers faced while teaching Costume History were mostly that ‘the pictorials in the text is not fully explainable’, the next were ‘most of the supplementary teaching materials or implements are not owned’, ‘have to explain very much in a short time’, and ‘the lectural explanation is insufficient’. 9. The solution for the difficulties that the highschool teachers faced while teaching Costume History was mostly ‘the information, on which audio-visual materials and implements are distributed in the market, should be easy to obtain’, the next opinions were ‘the school should provide enough experiment and practice expenses to buy audio-visual materials and implements’, and ‘education facilities of the Home Economics Department should be the main aspects in improving the teaching methods and should give special lectures about it’.

Korean traditional practice that gets a gravesite for burial and reckless grave establishment not only obstructs systematic national land management and reasonable urban development, but also causes a serious factor which has a harmful effect on natural environment and residential space in reality that our country is limited in area and national and social bases for use and establishment of graves are still inadequite. Though government and local governments have tried to cope with these problems by enacting legislation on funeral and others and so forth, they still have a variety of problems due to the shortage of grave management systems and information of accumulated individual graves. This study describes about the development of a GIS-based grave management system for making administrative management for individual cemeteries the prime object. As a result of application to a pilot area, the system developed in this study was able to be applied for supporting the time-limited burial system and managing cemeteries for those who left no relatives behind by constructing the database with grave-related position/attribute information which are collected by administrative system or direct survey. In addition, it is expected that this system will be utilized as a systematic management method that can be handed down the present or the future descendants under the tradition of the family-oriented funeral culture.
In this paper we expanded a existing web based B2B system to support users in low speed network. To guarantee shared dat a consistency between clients and a server, we proposed a method of data change detection by using a time stamp tree and the performance analysis of the proposed method was proved by a simulation. Under the worst condition that leaf nodes of a times tamp tree were changed uniform distribution, the simulation result showed that the proposed method was more efficient than a sequential detection until the percentage of changed nodes were below $15\%$. According to our observation, the monthly average of data change was below $7\%$ on a web-based construction MRO B2B system or a company A from April 2004 to August 2004. Therefore the Proposed method improved performance of data change detection in practice. The proposed method also reduced storage consumption in a server because it didn't require a server to store replicated data for every client.
The trend of the use of open softwares is increasing daily. Despite these increases in the use of open softwares, the importance of the problem of their quality is not considered enough. Also, if we look at the existing evaluation model which is used as the evaluation model of the existing open software, the level of the quantization is insufficient, the evaluator can show some subjectivity and as a clear evaluation method is not published, there are many problems to apply it in practice. Therefore, in this study, we have built an evaluation basis that can show consistent quantization without the influence of the evaluator and that can improve the evaluation speed with the automatization of the evaluation information acquisition. The built quality evaluation model will take an important role to evaluate and to improve the open software.
Regionalization technique using flow duration curve and spatial interpolation algorithm is developed for the purpose of estimating daily flow time series at ungauged station. In this study, we assumed a part of 8 gauging stations of Nakdong River basin as ungauged stations. Then, we generated flow duration curves and daily flow hydrographs by regionalization technique at ungauged stations. And we compared generated and observed hydrographs. The simulation results showed that the observed flows were well simulated by the proposed method and that the general patterns of the observed flows were satisfactorily reproduced by the regionalization technique. From these results, it is possible that we obtain daily flow information without application of labour intensive and time consuming deterministic models, which require complicating quantification of model parameter values. And we compared the regionalization techniques with the specific discharge method which is the most general approach in hydrological practice in Korea. The results showed that the regionalization technique was superior to specific discharge method.method.
