"History is a mirror" means that we should be prepared for the threats of enemies through learning from repeating history. Currently South Korea is facing various provocations, including North Korea's nuclear weapons and missile s. For the protection of the life and property of its people, South Korea should regard North Korea as a main enemy and be fully prepared for the threats. The Korean War was a war between well-prepared North Korea and ill-prepa red South Korea. After Liberation, North Korean army incorporated the Chinese Communist army, placed battle equi pment with the support of the Soviet army, and finished corps-level training while South Korea at that time did not finish battalion-level training. In wartime and peacetime, an army should improve military security by concealing its own information and find its enemy's information. North Korea carefully prepared for the war, collecting information about the organization, deployment and operation of the South Korean army. South Korean army failed to cope with it and had hard times in its early battles. In this paper, I will emphasize the importance of military security, focusing on the Battle of Gaeseong, the early part of the Korean War.

The purpose of this study was to examine the experiences of teachers during the development and performance of a nutrition education program based on collaboration between the school organization and local community, as the experiences of teachers who participate in a nutrition education program might be one of major factors to determine the success or failure of their performance. It's basic goal is give some suggestions on school nutrition education and to explore how to assist teachers to ensure their successful performance of a nutrition education program. As a result of analyzing the collected data, the experiences that the teachers had in the program planning stage were subcategorized into two groups: 'finding hope amid complaints' and 'building a learning community'. The experiences that the teachers had in the acting stage were subcategorized ino two groups as well: 'regulating, equalizing and forming a new schema' and 'building stepping stones'. The experiences that they had in the evaluation stage were also subcategorized into two groups: 'finding it rewarding and thankful to teach' and 'new challenge'. The findings of the study are expected to provide essential information on how to assist teachers to offer effective and successful nutrition education.

The objectives of this study were (1) to determine the preferences for three home economics curriculum Models(Concept-based curriculum Model, Competency-based curriculum Model, and Practical Problem-based curriculum Model) of Korean home economics(HE) teachers and HE teacher educators, (2) to determine the difference between HE teachers and HE teacher educators according to purposes of HE, focus of learning, organization of HE subject matter, focus of HE curriculum, focus of HE content, HE knowledge, main questions addressed through HE curriculum, teaching strategies, students’progress, and systems of action, and (3) to determine the relationships between preferences for three curriculum Models and personal and professional characteristics of HE teachers. Respondents in this study were 225 HE teachers and 35 HE teacher educators. The survey method was used in this descriptive study. The survey method was used in this descriptive study. The overall curriculum Model preference of each teacher respondent was determined by counting number of times a given Model among 10 identified variables. The data were analyzed by using Chi-square to compare the differences between the two groups. To determine the relationships between preferences for three curriculum Models and personal and professional characteristics of HE teachers, coefficient of contingency tables was used. Both of HE teacher group(79.4%) and HE teacher educator group(67.6%) preferred the practical problem-based curriculum Model the most. There was a difference between the two groups on preferences for the curriculum Models related to systems of action. No significant difference emerged when Chi-square was applied to determine difference between the two groups on overall preferences for three HE curriculum Model. The chi square values between preferences for three curriculum Model and level of school, type of school were statistically significant. Each contingency coefficient for level of school(middle school and high school) and form of school(private and public school) was 27, which means there is a low association between the preferences and level of school and the preferences and form of school.

This study was executed to verify the effects of individual and environmental characteristics of secondary-school teachers on teacher efficacy and job satisfaction. To do so, a survey of teacher efficacy and job satisfaction was conducted to 696 man and woman teachers from 55 secondary schools in Gwangju and Jeonnam province, and then the results of the survey were analyzed. In this study, teacher efficacy was composed as four factors: sense of calling, teaching-learning, colleague relation and school organization. And job satisfaction was categorized as three factors: job relation, compensation system and working environment. The Multivariate analysis results showed a significant difference in teacher efficacy and job satisfaction according to teachers' individual characteristics and working environment. Conclusively, teacher efficacy and job satisfaction are complicated factors formed by teachers' individual and environmental characteristics. To improve secondary-school teachers' teacher efficacy and job satisfaction, it is necessary to develop training and education programs reflecting individual and environmental characteristics.

Toxoplasma gondii is an intracellular Apicomplexan parasite and a causative agent of toxoplasmosis in human. It causes encephalitis, uveitis, chorioretinitis, and congenital infection. T. gondii invades the host cell by forming a moving junction (MJ) complex. This complex formation is initiated by intermolecular interactions between the two secretory parasitic proteins-namely, apical membrane antigen 1 (AMA1) and rhoptry neck protein 2 (RON2) and is critically essential for the host invasion process. By this study, we propose two potential leads, NSC95522 and NSC179676 that can efficiently target the AMA1 hydrophobic cleft, which is a hotspot for targeting MJ complex formation. The proposed leads are the result of an exhaustive conformational search-based virtual screen with multilevel precision scoring of the docking affinities. These two compounds surpassed all the precision levels of docking and also the stringent post docking and cumulative molecular dynamics evaluations. Moreover, the backbone flexibility of hotspot residues in the hydrophobic cleft, which has been previously reported to be essential for accommodative binding of RON2 to AMA1, was also highly perturbed by these compounds. Furthermore, binding free energy calculations of these two compounds also revealed a significant affinity to AMA1. Machine learning approaches also predicted these two compounds to possess more relevant activities. Hence, these two leads, NSC95522 and NSC179676, may prove to be potential inhibitors targeting AMA1-RON2 complex formation towards combating toxoplasmosis.

With the recent World Health Organization (WHO) Declaration of Pandemic for Coronavirus Disease-19 (COVID-19), COVID-19 is a global concern and many deaths continue. To overcome this, there is an increasing need for sharing information between countries and countermeasures related to COVID-19. However, due to linguistic boundaries, smooth exchange and sharing of information has not been achieved. In this paper, we propose a Neural Machine Translation (NMT) model specialized for the COVID-19 domain. Centering on English, a Transformer based bidirectional model was produced for French, Spanish, German, Italian, Russian, and Chinese. Based on the BLEU score, the experimental results showed significant high performance in all language pairs compared to the commercialization system.

In this study, we had tried to present a plan for improving the actual conditions of practical utilization of teaching material for 6th grade science developed by Ministry of Education & Human Resources Development and distributed to all elementary schools in Korea. Also we presented ways of better utilization of the teaching material after investigating the actual conditions of practical utilization. A survey was made to investigate and collect all data in the major metropolitan cities, the Kangwon, Chungcheong, Honam, and Kyeongsang area, respectively. We surveyed 316 6th grader teachers to investigate the actual conditions of distribution and utilization of teaching material as a general research. In addition, we surveyed 46 teachers to investigate the organization and content of teaching material as a particular research. The results are as follows. First, the teaching material was not approximately transmitted and kept to 6th grader teachers. Second, the utilization guide was not made. Third, it was reported that the thematic divisions of teaching material was a strong point, but the less detailed experiment manual was a weak point. Fourth, the consideration of content difficulties and simplicity was necessary to improve the material. Fifth, additional items should be included in the introductory presentation, convenience of reorganization, activity material causing learning interest, guidance of substitution experiment, and more concrete notice of experiment activity. Finally, there were positive responses of more than 4.0 point of Likert scale (1 to 5 point scale) in detail investigations of thematic items, which could have possibility that the teaching material was helpful to elementary school science field.

Brain gene expression information is closely related to the structural and functional characteristics of the brain. Thus, extensive research has been carried out on the relationship between gene expression patterns and the brain's structural organization. In this study, Principal Component Analysis was used to extract features of gene expression patterns, and genes were automatically classified by spatial distribution. Voxels were then clustered with classified specific region expressed genes. Finally, we visualized the clustering results for mouse hippocampal region gene expression with the Allen Brain Atlas. This experiment allowed us to classify the region-specific gene expression of the mouse hippocampal region and provided visualization of clustering results and a brain atlas in an integrated manner. This study has the potential to allow neuroscientists to search for experimental groups of genes more quickly and design an effective test according to the new form of data. It is also expected that it will enable the discovery of a more specific sub-region beyond the current known anatomical regions of the brain.
