Purpose: Earthquake disasters are frequently occur unpredictable situations due to various variables and unexpected situations. As a result, the work process itself is not uniform, making it difficult for public officials in the disaster safety department to familiarize themselves with the earthquake field manual. This paper is specifically and accurately grasp the current work situation conducted by the Disaster and Safety Countermeasures Headquarters of the Gyeongsangbuk-do Office and present a plan for designing serious game scenarios necessary for field manual learning. Method: In this study, scenarios were designed based on the GBS(Goal Based Scenario) model, and in the process of assigning missions and roles based on the Gyeongsangbuk-do earthquake field manual, public officials related to earthquakes were able to acquire knowledge and skills to solve practical tasks. Result: Scenario data of the proposed technique was implemented as a systematic procedure by processing various earthquake-related information into logical data and simplifying and abstracting it for game expression for earthquake situation training. Conclusion: In the event of an earthquake due to learning through serious games, related public officials of Gyeongsangbuk-do provincial are expected to be able to respond quickly to various earthquake disasters.

Background: In Korea, the population is rapidly aging, and the types of households for the elderly are also diversifying. The self-rated health of the elderly is a valuable health indicator that can comprehensively represent the overall quality of life along with physical, mental, and functional health. On the other hand, studies on the association between household type and self-rated health of the elderly are still insufficient. Thus, this study analyzed the association between household type and self-rated health by gender in Korean older adults. Methods: Using data from the analysis of the National Survey of Older Koreans 2017, 10,299 elderly people aged 65 and over were targeted. For the accuracy of the analysis data, 9,910 people were selected as the study sample by excluding proxy responses, those diagnosed with dementia, and non-response. And technical analysis, univariate analysis using the Rao-Scott chi-square test, and logical regression analysis involving survey characteristics were conducted by gender. Results: According to the adjusted model with all variables, in both men and women, the odds ratio of self-rated health 'bad' in 'couple (with ill spouse)' was significantly higher than 'couple (with spouse)'. It was 2.54 (95% confidence interval [CI], 2.05-3.15) for men and 2.11 (95% CI, 1.70-2.62) for women. In addition, the odds ratio of self-rated health 'bad' in 'living with adult children' was 1.43 (95% CI, 1.09-1.87) for men and 1.42 (95% CI, 1.15-1.75) for women, which was more significant in women than men. Conclusion: This study states that there is an association between gender, household type, and self-rated health of the elderly, and the health of a spouse and cohabitation with children have a significant effect on self-rated health. As a result, in order to improve the health status of the elderly, health promotion and health care policies involving the characteristics of the elderly's gender and household type are needed.

With the activation of OTT and VOD services, the viewing behavior is rapidly changing, but the programming regulation has not escaped the ratio regulation in the same way as in the past. Therefore, this paper aims to examine the policy validity of the current organization ratio regulation and to suggest improvement directions based on this. To this end, the policy objectives and background at the time of the introduction of the domestic organization ratio regulation were considered and compared with the current status of the broadcasting market. As a result, this study found that it is difficult to apply the logical framework of asymmetric regulation at the time of the formation ratio regulation into the current status of broadcasting market, the existing framework was established and hold in the mutual relationship of various stake holders formed based on the asymmetric regulation. It was pointed out that the typical pattern of path dependency repeating only fine adjustment of ratio was shown. Based on this, this study suggests that it needs to be divided into the regulation by the public interest and the regulation by the industrial purpose according to the purpose of regulation, and it is necessary to be limited to the direct regulation corresponding to the public interest of the viewer. Also this study proposes that it is necessary to separate the regulation from promotion policies as well as to resolute asymmetric regulation in broadcasting policies.

The purpose of this study is to present a reflective review of the earth and universe units from the revised elementary curriculum of 2007-2015 and suggest changes in the 2022 revised curriculum. For this purpose, we conducted an FGI with earth science educators and elementary school teachers regarding the content elements and system, the achievement standards and inquiry activity composition, and the vertical and horizontal curriculum connectivity. Free response and weighted hierarchical analysis items were incorporated into the FGI to ensure logical consistency of the inductively derived improvement. This analysis revealed that the composition of units by grade group had been unevenly distributed among each of the "earth systems" until the 2015 revised curriculum was finalized. Furthermore, the basic concept was still insufficient. We suggest that achievement standards centered on the learning content and skills must state specific scientific core competencies, and inquiry activities should include rigorous critical thinking, student written responses, and student inquiry and analysis. In the hierarchical analysis items, FGI emphasized the inclusion of essential content elements rather than reduction of content elements, understanding-oriented concept learning rather than interest-centered phenomenon learning, basic concept division learning before integration between subjects, and expanding vertical-horizontal connectivity rather than repeating and advancing learning. There is a limit to the generalizing the suggestions proposed in this study to the common opinion of elementary earth science experts. However, since the main vision of the 2022 revised curriculum is to gather opinions through educational entities' participation in a variety of educational subjects, it is suggested that our results should be incorporated as one of the opinions proposed for the 2022 curriculum revision.

The book is a footnote of life and memory, a sign of knowledge and intelligence, including divinity and reason, idols and destruction, praise and curse, arrogance and prejudice, truth and falsehood. The past emperors, monarchs, priests, and rulers have been controlled or slaughtered by censorship and prohibition, burning and destruction, etc. In ancient history, archaeology, war history, cultural history, and library and information science, many studies have been conducted on the burning and destruction of books, but the Western perspective is dominant, and there are nationalistic approaches and logical leaps. This study traced the truth about the destruction of the Royal Library of Alexandria in Egypt, destruction of the Baghdad libraries by the Mongol Empire, and burning more than 200,000 volumes of Korean historical documents of Japanese Government-General in Korea among the major bibliocausts with many mysteries and controversial issues in the East and West. As a result, the Royal Library of Alexandria is most likely destroyed under the rule of the Roman Empire. The massacre of the Baghdad library by the Mongolian army is a historical fact, not the manipulation and extreme exaggeration of western society. And Korean historical documents have been stolen and burned by the Government-General of Chōsen for 35 years and should be recognized as '200,000 + α'. Lastly, On the premise of excavating historical materials, research to investigate the truth behind the blibiocaust or libricide should be continued.

Exercise is necessary for a healthy life, but it is recommended that it be conducted in a non-face-to-face environment in the context of an epidemic such as COVID-19. However, in the existing non-face-to-face exercise content, it is possible to recognize exercise movements, but the process of interpreting and providing feedback information is not automated. Therefore, in this paper, to solve this problem, we propose a method of creating a formalized rule to track the contents of exercise and the motions that constitute it. To make such a rule, first make a rule for the overall exercise content, and then create a tracking rule for the motions that make up the exercise. A motion tracking rule can be created by dividing the motion into steps and defining a key frame pose that divides the steps, and creating a transition rule between states and states represented by the key frame poses. The rules created in this way are premised on the use of posture and motion recognition technology using motion capture equipment, and are used for logical development for automation of application of these technologies. By using the rules proposed in this paper, not only recognizing the motions appearing in the exercise process, but also automating the interpretation of the entire motion process, making it possible to produce more advanced contents such as an artificial intelligence training system. Accordingly, the quality of feedback on the exercise process can be improved.

In this study, elementary students' science communication competence was investigated based on the grammatical features expressed in their language-use in classroom discourse and science writings. The classes were designed to integrate the evidence-based reasoning framework and traditional learning cycle and were conducted on fifth graders in an elementary school. Eight elementary students' discourse data and writings were analyzed using lexico-grammatical resource analysis, which examined the discourse text's content and logical relations. The results revealed that the student language used in analyzing data, interpreting evidence, or constructing explanations did not precisely conform to the grammatical features in science language use. However, they provided examples of grammatical metaphors by nominalizing observed events in the classroom discourses and those of causal relations in their writings. Thus, elementary students can use science language grammatically from science language-use experiences through listening to a teacher's instructional discourses or recognizing the grammatical structures of science texts in workbooks. The opportunities in which elementary students experience the language-use model in science learning need to be offered to understand the appropriate language use in the epistemic context of evidence-based reasoning and learn literacy skills in science.

In this paper, research was conducted to solve the problem of reducing the dimming level and flicker that occurs in the visible light communication system. Visible light communication is a convergence technology that provides both communication and lighting, and must satisfy not only communication performance but also lighting performance. However, since the existing data transmission method transmits without considering the transmission data sequence, it reduces the dimming level and causes a flicker phenomenon. To solve this problem, in this paper, the Dimming Improvement and Flicker Reduction Mapping technique was studied. Existing systems simply transmitted data of '0' and '1', but in this system, original data transmission channels and DIFR (Dimming Improvement and Flicker Reduction) transmission channels are assigned to RGB channels. Original data is allocated to the R channel and original data or inverse original data is allocated to the DIFR-G channel, and the DIFR-B channel maintains the maximum dimming level by transmitting through the logical operation of the R channel and the G channel. At the same time, the flicker phenomenon is prevented by preventing continuous occurrence of 'OFF' patterns. Through this, we proposed an adaptive data allocation algorithm that can faithfully play a role as a light as well as a communication function.

The medical information system is an effective medical diagnosis assistance system which offers an environment in which medial images and diagnosis information can be shared. However, this system can only stored and transmitted information without other functions. To resolve this problem and to enhance the efficiency of diagnostic activities, a medical image classification and retrieval system is necessary. The medical image classification and retrieval system can improve efficiency in a medical diagnosis by providing disease-related images and can be useful in various medical practices by checking diverse cases. However, it is difficult to understand the meanings contained in images because the existing image classification and retrieval system has handled superficial information only. Therefore, a medical image classification system which can classify medical images by analyzing the relation among the elements of the image as well as the superficial information has been required. In this paper, we propose the method for learning and classification of brain MRI, in which the superficial information as well as the spatial information extracted from images are used. The superficial information of images, which is color, shape, etc., is called low-level image information and the logical information of the image is called high-level image information. In extracting both low-level and high-level image information in this paper, the anatomical names and structure of the brain have been used. The low-level information is used to give an anatomical name in brain images and the high-level image information is extracted by analyzing the relation among the anatomical parts. Each information is used in learning and classification. In an experiment, the MRI of the brain including disease have been used.

2021, the Supreme Court recognized the foundation of the quasi-indecent act by force by the concept of 'alcohol blackout' although there were multiple situations that it was hard to judge insanity of the victims was evident in the cases with drunken victims. This means the consideration of insanity state due to temporary false memory rather than the total loss of mental capacity from the existing concept of insanity. However, the interpretation of insanity in the criminal law has to be strict and its application could be difficult. In particular, the comparison precedent which is very similar to the subject one was determined not to be the same with the state of the insanity or inability to resist during the sexual relation though the victim had the symptoms of alcohol blackout, denying the quasi-indecent act by force. This argument is determined to be logical remarkably, and insanity and quasi-indecent act by force should be discussed considering the medical review on the alcohol blackout of the victims sufficiently when determining the individual precedents. In addition, the most important point in the sexual crimes is the consent, and there may be possibility of negligence in case that uncertain consent is determined as the consent to continue the following act. Also, in case of uncertain consent or suspicious, universal determination not to follow the act should be able to realized. Therefore, strong evidence is required for criminality, determining that the victim is the state not to be able to do the normal judgment and the minimum willful negligence is existed that the accused uses this. In the subject ruling, the act of the accused has to be clearly punished, however, it is determined to be unreasonable for the punishment with the quasi-indecent act by force under the interpretation of the current regulations.
