To enhance the credibility of human reliability analysis, various kinds of data have been recently collected and analyzed. Although it is obvious that the quality of data is critical, the practices or considerations for securing data quality have not been sufficiently discussed. In this work, based on the experience of the recent human reliability data extraction projects, which produced more than fifty thousand data-points, we derive a number of issues to be considered for generating meaningful data. As a result, thirteen considerations are presented here as pertaining to the four different data extraction activities: preparation, collection, analysis, and application. Although the lessons were acquired from a single kind of data collection framework, it is believed that these results will guide researchers to consider important issues in the process of extracting data.

Researchers examined elementary school children's experiences and the way that their mothers scolded them. In their writings, the children reported that their mothers under-estimated them, and assumed that they were not able to do anything by themselves. This reflected on the way that the mothers disciplined their children. The mothers were not a good model of proper behavior and did not treat the siblings fairly. The mothers were directive and valued results over effort. The children confessed that they felt suicidal, miserable and wanted to run away from home. They had a love-hate relationship with their mothers. They had to hide their real feelings and show love and respect towards their mothers. They had conflicts in dealing with these feelings. Their inability to show their real feelings and their dependency on their mothers made them return home, much like a boomerang. As a result, the children learned how to respond quickly in avoiding scolding situations. Furthermore, they learned the most important lesson; that it is all right to be abusive as long as it is for their or anybody else's own good.

PMS(Plant Monitoring System) for simulation is the program for training that users such as instructor, operator, and supervisor can operate the plant virtually. Presented in this paper, are some lessons learned from implementation of PMS for simulation. First, this PMS fer simulation is based on LINUX instead of UNIX. These two OS(Operating System) have different platform and compiler version on it, so debugging needs to be done about variable defining part. Second, In LINUX system, the size of shared memory and message queue is already designated as a default value that user has to set up and use the RTAP DB. Third, to decrease the dummy data size, it has to be changed into binary formation. Lastly, PMS software for simulation provides several environments according to the command, so considered should be status monitoring, alarm, system organization, point and group monitoring, history storage and searching function.

Globally, COVID-19 has significantly impacted many different organizations and people. From the banks' perspective, this pandemic has affected banks' corporate and retail customers. Also, banks had to adjust to distributed workforce model. This paper analyses the lessons learned from the COVID-19 pandemic, which can be effectively used to rebuild banks' Operational Risk Management capabilities. The present study used the survey research methodology, which includes structured questionnaires completed by senior banking professionals to analyze the learnings from COVID-19 and understand the distributed workforce model and remote working effectiveness. Findings: The Pandemic accelerated the pace of digital transformation. The lockdown imposed due to the pandemic led to employees working remotely, which has been effective because of enhanced digital capabilities. However, enhanced monitoring is required to prevent data-related issues, and action needs to be taken to address challenges faced in having a remote distributed workforce model, like negative impact on on-the-job learning, data-related risks, and employee wellbeing. COVID-19 is an unprecedented event that could not have been predicted in any scenario analysis. This crisis has highlighted various systemic drawbacks that need to be addressed. Banks can apply the lesson learned from this Pandemic to become more robust in the future.

The study was performed to investigate the dietary behaviors and attitudes toward the lesson of Food and Nutrition in Home Economics course among middle school students in rural area. The participants of the study were 647 second-grade students in a middle school in Geumsan-gun, Chungcheongnam-do. The main nutrition problems of the students were found to be deviated food-intake habits and irregular meal time. Twenty six percent of female students and 14.8% of male students skipped breakfast. Seventy three percent of the total students have a tendency of food aversions. The food groups they dislike most were vegetables and pulses. They answered they got nutrition information mostly from the class at school. Their favorite topic in the lesson of Food and Nutrition was cooking. Some students did not like Food and Nutrition because it requires too much memorization. Teaching methods they liked were lecture, discussion, and audio-visual presentation. Although 81.7% of the students thought that the lesson of Food and Nutrition was useful, only 17.1% of the students practiced what they learned from the lesson. These results confirm that nutrition education in middle school is essential to the students in rural area and that it is needed to find an effective teaching method and materials for them to change positively their food behaviors at daily life.

이 연구는 사회적기업이 소수자 보호정책으로 어떠한 의미를 가지는가에 대해 본질적으로 접근하였다. 특히, 소수자정책에 많은 영향을 미치는 북한이탈주민들과 사회적기업과의 관계를 중심으로 논의하였다. 연구결과를 요약해 보면 다음과 같다. 첫째, 북한이탈주민들이 대한민국 사회에 적응하는데 가장 큰 어려움은 경제활동, 사회적 이질감인데, 사회적기업은 놓은 효과성을 가진 정책이라는 점을 알 수 있었다. 둘째, 기존의 사회적기업이 지나치게 중앙정부 위주로 진행되어져 창의와 발전이 결여된 지원 모형이였다는 점이다. 이러한 문제를 해결하기 위해서는 민관협동형 정책모형으로 변화해야 한다는 교훈을 얻을 수 있었다. 셋째, 사회적기업은 단순한 경제활동 수준을 넘어, 사회, 문화, 생활, 언어 등의 사회교육의 순기능을 가지고 있으므로 북한이탈주민들의 사회적기업 참여를 일정부문 의무화해야 한다는 교훈을 얻을 수 있었다. 이러한 연구결과는 소수자정책으로써 북한이탈주민과 사회적기업의 관계를 설명하는데 이론적으로 기여할 것으로 판단된다.

One of the historical origins of the modern science education was investigated in this paper. From the view point of the pansophistic educational philosophy which emphasized "man should teach completely all things to all mankind(Omnes, Omnia, omnino)", J.A.Comenius proposed in his book "Didactica magna"(1658) that 'physica' should be learned as one of the most important school subjects. He suggested the completion of human being as a wholeness of the universe could be achieved through the physics teaching. His ideas of science education was, however, directed not to the 'rational konwledge' about the natural world, but to the 'divine wisdom'. His main thoughts and influences on science education can be summarized as follows: 1) The human being as a God's image should know the divinely created nature, because the invisible God's existence can be sensorially recognized in the nature. 2) Physics or science should be regarded as more important objects than verbal learning in general school education. 3) The cognitive union between the words('representative' or 'das Dargestellte') and things('presentative' or 'das Dargebotene') can be achieved through the objects lesson ('Anschauungsunterricht') 4) The realistic and sensor-cognitive learning theory of the object lesson is yet very important especially in the science education of elementary school, even though the inquiry learning process has became more important in the last years. 5) The religious aspect of his idea could not satisfy the social needs of industrialization and the development of professonal technics in the 18 to 19th century.

This paper presents a case study in which a lesson was designed and applied to enhance preservice home economics teachers' instructional design competence using the metaverse. For 15 weeks from March 6 to June 14, 14 students enrolled on the course 'Multimedia Home Economics Education' for preservice home economics teachers used the metaverse to engage in problem-based learning to solve instructional design problems in home economics classes. In accordance with the ADDIE design model, in the analysis stage, we assessed preservice home economics teachers' level of knowledge of lessons using the metaverse, and their perceptions of the possibility, necessity, and usefulness of using the metaverse in home economics lessons. In the design and development stage, lesson plans, questions for problem-based learning, assessment tools, and teaching and learning materials were developed. The implementation was conducted in parallel with training on understanding multimedia and the metaverse, and instructional design competence was evaluated through pre- and post-testing and reflection journals. The results revealed that the preservice home economics teachers acquired a good understanding of lessons using the metaverse, learned how to design lessons for self-directed learning by applying the metaverse to their home and classroom, and gained confidence in applying it to their teaching practice or in-service work. It is expected that the results of this study will be used as support materials for prospective and current home economics teachers to design home economics lessons using the metaverse, thereby expanding the horizons of home economics education.
