This study investigated the recognition and difficulty of Christian early childhood education curriculum of Christian early childhood education by analyzing cases of Christian early childhood curriculum experienced by 10 Christian early childhood teachers with more than 4 years of experience in the metropolitan area. From April 4 to June 24, 2018, data were collected by transcribing through a total of 22 interviews: individual interviews (20 times) and group interviews (2 times). In order to categorize the interview data, derive the core categories, and increase the accuracy and validity of data interpretation, it was sent to the study participants for member check and verified by two early childhood education experts. As a result, the perception and difficulty of Christian early childhood teachers' perceptions and difficulties in the Christian curriculum were analyzed as 'Applying Church Education to Nuri Course', 'Applying Nuri Course to Church Education', and 'Learners Understanding for Integration of Church Education and Nuri Course' did. It is hoped that the understanding of the Christian early childhood curriculum will be helped through the recognition and difficulty of the Christian early childhood curriculum experienced by Christian early childhood teachers, and will be provided as basic data for finding a desirable Christian early childhood curriculum.
In January 2020, COVID19 plunged the whole planet into a pandemic. This has caused great economic losses and is causing social confusion. COVID19 has a superior infection rate among people with underlying disease such as heart disease, high blood pressure, diabetes, stroke, depression, and cancer. In addition, it was studied that patients with underlying disease had a higher fatality rate than those without underlying disease. In this study, the presence or absence of underlying disease was classified using EEG data. The data used to classify the presence or absence of underlying disease was EEG data provided by Data Science lab, consisting of 33 features and 69 samples. Z-score was used for data pretreatment. Classification was performed using the neural network NEWFM and ZNN engine. As a result of the classification of the presence or absence of the underlying disease, the experimental results were 77.945 for NEWFM and 76.4% for ZNN. Through this study, it is expected that EEG data can be measured, the presence or absence of an underlying disease is classified, and those with a high infection rate can be prevented from COVID19. Based on this, there is a need for research that can subdivide underlying disease in the future and research on the effects of each underlying disease on infectious disease.

Objectives: This study was conducted to evaluate perceptions of safety and risk among Korean industrial hygienists and the change between before and after the Sewol Ferry Disaster in 2014. Two surveys with questionnaires composed of 51 questions were completed by attendees of the Korea Industrial Hygiene Association(KIHA) conference. Methods: One was conducted at the 2013 KIHA Fall Conference(N=181) and the other was from the 2014 KIHA Summer Conference(N=123). Between these two surveys was the Sewol Ferry Disaster on April 14, 2014, which was believed to seriously affect safety and risk perceptions in Korea. Results: It was revealed that industrial hygienists' awareness of safety rules strengthened after the Sewol Ferry Disaster(p<0.05). It was apparent that people over the age of 30 were more sensitive to social safety. There was no significant difference in the evaluation and attitude regarding governmental safety policy between the years of 2013 and 2014. The credibility of public organizations responsible for the disaster management system decreased. The self-evaluation of respondents' safety level also decreased. This trend shows mainly in the younger generation. It was evaluated that the overall social safety level decreased and the anxiety level increased. The score on social safety on a ±5 Likert scale was 0.68 in the 2013 survey and -0.33 in the 2014 survey(p<0.05). It was reported that the most serious threat factors for accident or disaster were 'building collapse > illegalities and corruption > side effects of radiation therapy >accidents in normal activity > occupational disease,' in order. They picked 'safety ignorance > hurry-up habits and culture > focusing on short-term benefit > easy-going attitude > insufficient safety education' for the causes of low social safety levels in 2013. In 2014, they were 'safety ignorance > easy-going attitude > focusing on short-term benefit > insufficient safety education > hurry-up habits and culture'. Conclusions: This study has some limitations because it was originally not designed to survey attitudes prior to the Sewol Ferry disaster in 2013. In addition, the survey targets are industrial hygienists who are familiar with occupational disease and injury.

Objectives: In order to reduce the burden on employers and increase the reliability of measurement results, improvements to the provisions related to the work environment measurement reporting system, such as the current Occupational Safety and Health Act and its Enforcement Rules, are planned. This study aimed to suggest improvements for the work environment measurement reporting system through a survey and Delphi investigation. Method: This survey included workplaces (health managers), national institutions (the Ministry of Employment and Labor) that use the results of the work environment measurement reporting system for policy and supervision purposes, and work environment measurement institutions that enter the results were included. In addition to the survey, we tried to derive results through meetings with stakeholders and expert advisory meetings. Results: It is difficult to abolish or partially improve the reporting system under the Enforcement Regulations of the Occupational Safety and Health Act at this point because the opinions of workplaces, supervisory agencies, and measuring agencies differ in terms of its intended purpose and use. In the case of high-exposure harmful factors (over 50% on the basis of exposure) in the "comprehensive opinion" described in the work environment measurement results table, it is necessary to insert unit of work with exposed harmful factors, exposure factors, and current conditions in checklists or tables so that they can be reflected in government policies. In the case of workplaces that are feared to be highly exposed to substances subject to measurement, it seems desirable to improve them so that industrial health instructors registered with the Korea Safety and Health Agency or local labor offices can provide technical guidance. As an improvement plan to increase the reliability of data and the use of big data, it is necessary to improve the input method for processes and jobs. Conclusion: The laws and regulations of the work environment measurement reporting system are difficult to revise due to a lack of consensus among current stakeholders, but improvements can be achieved by improving the Ministry of Employment and Labor's notifications and other means. In addition, in order to effectively utilize the data from the K2B system, it is necessary to improve the input method for processes and jobs.

Hoseonmu belongs to the genre of a composite of song, music, and dance. At that time, there was no widely known record of Hoseonmu in Baekje, but it is clear that it was popular enough to be invited to Changan by Emperor Yang of Sui. The musical instruments, songs, and dances were analyzed through the research method of literature and the content of the Hoseonmu version was established. The setting of the stage for the performance of Baekje instrumental music reveals its characteristics through sabangak from Gigaku in the neighboring countries. The stage for Hoseonmu was set up utilizing the creation of the imperial performance stage in the Baekje instrumental music. In particular, Hoseonmu has two types: heavenly and earthly. The heavenly Hoseonmu can be found on the wall of the Cave No. 220 formed in the Chodang (618-707) era. They include Dongbang Pharmacopoeia jingbian and Western Paradise jingbian. Hoseonmu would have chosen to be the fast-paced spinning dance. Motions for Hoseonmu could be set up through them. Meanwhile, Mimaji's instrumental dance is presented. Six dancers appear in two turns of the performance. Four dancers in front row and other two in the back are dressed up as hunters, wearing goblin masks, and holding flowering plum tree branches in their right hands. Through this, the movements and costumes of Hoseonmu are reproduced in more detail. Various sectors of education, theater, dance, and tourism in the Hoseonmu contents of Baekje instrumental music contributed to the Korean Wave.

Objectives: 'Confined space' was only defined in the Safety and Health Regulations as a place where oxygen deficiency and hydrogen sulfide must be dealt with at the time of the initial enactment (1982). The danger of fire and explosion were added in 2003. We will compare and review the regulations related to confined space work under the current safety and health rules alongside regulations in other countries and prepare a plan to improve the system through enhanced clarity and execution. Methods: In a comparison of systems for the prevention of suffocation in confined spaces in major countries (Germany, United States, Japan) different concepts of the definition of confined spaces in different countries apparently due to differences in each country's legal implementation system, accident analysis methods, the status of safety and health implementation in workplaces, the precautions against actual confined space work, and the definition of confined spaces were found to be not much different between Korea and the other foreign countries. Results: In the case of Germany and the United States, a confined space is defined as a contextual concept rather than a place, so more careful attention is needed from operators or enclosed space managers as it is often necessary to judge the actual workplace. In the case of Korea and Japan, the interior of the place is mainly defined as a place, especially in the case of Japan, which concentrates on oxygen deficiency and hydrogen sulfide poisoning. Conclusions: For measures to improve regulations on the prevention of suffocation accidents in Korea, I would like to propose three major measures to improve the system in the rules on domestic industrial safety and health standards. It is necessary to prepare and provide a guide to ensure that the 18 types of confined spaces currently defined as confined spaces are clearly understood by field management supervisors or workers.

Atractylodes japonica has been widely used in a traditional Korean herbal medicine exerting various pharmacological activities such as diauretic action, asriction, anti-allergy, neuroprotective activity, anti-cancer, immunomodulation and gastrointestinal protective effect. This study was to investigate the antioxidant, nitric oxide and inflammatory cytokines production of A. japonica extract by water and 70% ethanol. DPPH and ABTS free radical scavenging activity were increased in a dose-dependent manners with both extracts and there was no difference with extract solvents. 70% ethanol extract of A. japonica showed a very strong inhibitory effect on NO production. Both extracts of A. japonica significantly reduce the expression of iNOS and COX-2 proteins involved in NO prodction. A. japonica extract by water and 70% ethanol inhibited LPS-induced proinflammatory cytokines such as IL-6 and IL-1b. In this study, 70% ethanol extract of A. japonica significantly suppresses LPS-induced NO and inflammatory cytokine production. Therefore it can be widely used to treat and improve inflammatory diseases.
