The contents of high school 'Common science' textbooks was analyzed qualitatively and quantitatively. Seven common science textbooks were selected and its contents, structure, inquiry, activities, appendix and its characteristics were investigated, and analyzed using the Goal Clusters of Project Synthesis and Romey's indices of text evaluation were calculated. The contents of each unit are not much different among textbooks because they are written according to the curriculum ordinance and textbook guidelines of the Ministry of Education. The textbooks was consist of $471{\sim}519$ pages. It was distribute similarly among the chapter of 'materials', 'forces', lives' and 'earth'. The chapter of 'energy' and 'environment' was treat significantly. The contents and structure of common science is a mere physical consolidation. I make an alternative plan that a topic form. Inquiry activities used in the textbooks are 11 type, however most of that is interpretation of data, experiment, survey and discussion. Ninety six percents of the experiment, belong to the 1st level, four percents of that belong to the 2nd level of the Schwab's inquiry level and there are no activities of the 3rd level. Little attention is given to Goal Cluster I, II, IV in the common science textbooks currently employed. Its content should be broadened to include all Goal Clusters of Project Synthesis. Homey's indices representing the degrees of student involvement. are $0.57{\sim}1.14$ for sentence analysis, $0.60{\sim}1.67$ for figure and diagram analysis, $0.67{\sim}1.50$ for analysis of questions at chapter ends, respectively, student activity per page investigated being $0.6{\sim}0.9$. But chapter summaries cease to repeats the conclusions of the chapter also it be rather formally and inattentively written.

Natural products have been used to mitigate the effects of cancer and infectious diseases, as they feature diverse bioactivities, such as antioxidant, antibacterial, anti-inflammatory, and immunomodulatory effects. Here, we chose 10 natural products that are well-known as pulmonary enhancers and investigated their bactericidal effects on Streptococcus pneumoniae. In the disk diffusion assay, the growth of S. pneumoniae was significantly regulated by G. fructus treatment regardless of extraction method used. We first adopted spraying as a novel delivery method for G. fructus. Interestingly, mice exposed to G. fructus three times a day for 2 weeks were resistant to S. pneumoniae intranasal infection (shown both through body weight loss and survival rates compared to the control group). Moreover, we confirmed that exposure to G. fructus regulated the colonization of the bacteria despite the sustained inflammation in the lung after exposure to S. pneumoniae, indicating that migrated inflammatory immune cells may involve a host defense mechanism against pulmonary infectious diseases. While a similar number of granulocytes (CD11b⁺Ly6C⁺Ly6G⁺), neutrophils (CD11b⁺Ly6C^intLy6G⁺), and monocytes (CD11b⁺Ly6C^intLy6G^-) were found between groups, a significantly increased number of alveolar macrophages (CD11b⁺CD11c^hiF4/80⁺) was detected in BAL fluids of mice pre-exposed to G. fructus at 5 days after S. pneumonia infection. Taken together, our data suggest that this usage of G. fructus can induce protective immunity against bacterial infection, indicating that facial spray may be helpful in enhancing the defense mechanism against pulmonary inflammation and in evaluating the efficacy of natural products as immune enhancers against respiratory diseases.

The purpose of this study was to investigate COVID-19 Knowledge, Risk Perception, Anxiety and Preventive Behaviors, and to identify the influencing factors on Preventive Behaviors of nursing students. Data were collected using questionnaires from 342 nursing students in Gwangju, November 2021. The collected data was analyzed by descriptive statistics, pearson's correlation coefficient and stepwise multiple regression using IBM SPSS 21.0 program. The total mean scores were as follows: COVID-19 Knowledge, 13.25±1.38; Risk Perception; 4.57±1.34, Anxiety; 44.55±9.66, Preventive Behaviors; 7.66±1.55. Preventive Behaviors was found to have significant positive correlations with COVID-19 Knowledge and Risk Perception). The most influential factors influencing the Preventive Behaviors of nursing students were Experience in education related COVID-19 prevention, Risk Perception, COVID-19 Knowledge. In conclusion, in order to develop the Preventive Behaviors of nursing students, it is necessary to apply a program that improve the COVID-19 prevention education and Knowledge, and to control Risk Perception according to the individual level.

The purpose of this study was to explore high school teachers' subjective perception on performance-based pay system(PBPS) for teachers using Q-methodology. This study found three types of high school teachers' subjective perception on the system. Type I is named 'the type of negative perception.' The subjects of type I emphasize the PBPS is not appropriate system for motivating teachers' educational behaviors. Type II is named 'the type of neutral perception.' The subjects of type II emphasize the PBPS is a fair job evaluation, strengthening cooperative atmosphere of educational community but the system is not an usefulness for causing educational behavior etc. Type III is named 'the type of acceptive perception.' The subjects of type III emphasize the PBPS is a good policy to reward for the work most people avoid getting into and improve culture of teaching job etc.

Although the life-sustaining treatment decision law is in effect, health care worker have many difficulties in determining life-sustaining treatment. Therefore, the relationship between the awareness of well-dying(WD), the attitude toward withdrawal of life-sustaining treatment(AWLST), and the attitude toward euthanasia(AE) for nursing students who will take care of dying patients in the future will be analyzed and used as basic data for bioethics classes. The study period was from April 1 to May 6, 2018, and a survey was conducted on 288 nursing students in D City. As a result of the study, WD was found to have positive (+) correlations with AWLST and AE, while AWLST was positive (+) with active and passive euthanasia. As nurses are expected to experience many ethical conflicts in the life-sustaining treatment process, it is necessary to receive education related to well-dying awareness, bioethics education, and life-sustaining treatment during the nursing student period.

It is necessary to understand the amount of snowfall and area of snow cover of Mt. Halla to ensure the safety of mountaineers and to protect the ecosystem of Mt. Halla against climate change. However, there are not enough related studies and observation posts for monitoring snow load. Therefore, to supplement the insufficient data, this study proposes an analysis of snow load and snow cover using normalized-difference snow index. Using the images obtained from the Sentinel2 satellite, the normalized-difference snow index image of Mt. Halla could be acquired. This was examined together with the meteorological data obtained from the existing observatory to analyze the change in snow cover for the years 2020 and 2021. The normalized-difference snow index images showed a smaller snow pixel number in 2021 than that in 2020. This study concluded that 2021 may have been warmer than 2020. In the future, it will be necessary to continuously monitor the amount of snow and the snow-covered area of Mt. Halla using the normalized-difference snow index image analysis method.

This study conducted a survey using Google Survey targeting 415 college students over the age of 20 to investigate college students' perceptions of the COVID-19 vaccine. As a result, the average result of 'I think the COVID-19 vaccination is necessary' for herd immunity was 3.90, and 65.8% of the 'necessity of vaccination' recognized the 'necessity of vaccination', but 35.4% negatively evaluated 'the safety of the vaccine'. showed. As for the intention to vaccinate against COVID-19, 34.7% said 'I will vaccinate as soon as the order arrives'. This showed that the current COVID-19 vaccination is not positive. As the reasons for not wanting to be vaccinated, 65.3% answered 'adverse reaction to the vaccine' and 25.8% 'distrust of the vaccine itself'. In addition, they perceived the vaccine supply between developed and underdeveloped countries as unequal, and the average was 3.94, indicating that they were afraid of adverse reactions to the COVID-19 vaccine. Therefore, in order to more effectively acquire information about the COVID-19 vaccine, research, platform development, and education on publicity methods through the media frequently used by college students are required.

This study was conducted to understand the relationship between college students' motivation to choose a major and their intention to acquire a certificate. As a result of the study, only social motivation among the motives for choosing a major influenced the intention to obtain a certificate. Second, only social motivation influenced the perception of the value of using certificates. Third, in the relationship between the motivation for choosing a major and the intention to acquire a certificate, the perception of the value of using a certificate did not affect. Based on these research results, this study confirmed that in the case of departments related to health and medical fields, students with strong social motivation such as employment have a high willingness to obtain certificates.
