The Trends in International Mathematics and Science Study (TIMSS) announced the TIMSS 2015 results at the end of 2016. In this research, we analyzed the relationship between Korean eighth grade students' attitude toward science and science achievement, trends in students' attitude toward science based on common items used in three to four cycles of TIMSS, and trends across grades in students' attitude toward science. According to the results, Korean eighth grade students showed the lowest level of confidence with science, interest in learning science, and valuing science among the 15 top performing countries as well as all the participant countries. In addition, according to the analysis result of common items, Korean students' confidence with science and interest in learning science have decreased, whereas students' valuing science with instrumental values has increased between TIMSS 2011 and TIMSS 2015. According to trends across grades, the cohort of students, assessed at the fourth grade in TIMSS 2011 and moved to the eighth grade four years later in 2015, decreased in their confidence with science and interest in learning science. Discussed in the conclusion are further studies and ways to improve science teaching and learning to improve students' attitude toward science.

This study evaluated the effects of knowledge, attitude, confidence and skills in pre-post and 3months after of CPR education on female nursing students. 49 nursing students were participated. Data were analyzed through descriptive analysis, t-test, repeated measure ANOVA and Bonferroni correction using SPSS/WIN 18.0. The results showed that although scores of knowledge of CPR were significantly increased from 14.47 to 16.71, 3 months after was decreased to 14.96 (F=36.77, p<.001). Scores of attitude were increased from 14.96 to 16.76, but decreased to 15.39 in 3 months (F=27.59, p<.001). There were significantly increased in scores of confidence from 29.39 to 32.55. Otherwise, 3months after was revealed 30.22 (F=19.50, p<.001). Skills were significantly decreased from $10.94{\pm}0.24$ after CPR education to $6.4{\pm}1.62$ in 3 months(t=21.22, p<.001). In conclusion, this research implies the needs of re-education on CPR before 3 months for effects and retention of CPR education.
The purpose of this study was to analyze whether nonemergency, isolated coronary artery bypass graft (CABG) surgery for high- or low-risk patients biases the assessment of the risk-adjusted mortality rates of hospitals. This study used 2002 National Health Insurance claims data for tertiary hospitals in Korea. The study sample consisted of 1,959 patients from 23 tertiary hospitals. The risk-adjustment model used the patients' biological, admission, and comorbidity data identified in the claims. The subjects were classified into high- and low-risk groups based on predicted surgical risk. The crude mortality rates and risk-adjusted mortality rates for low-risk, high-risk, and all patients in a hospital were compared based on the rank and the four intervals defined by quartile. Also, the crude mortality rates of the three groups were compared with their 95% confidence intervals of predicted mortality rates. The C-statistic (0.83) and Hosmer-Lemeshow test ($X^2$=11.47, p=0.18) indicated that the risk-adjustment model performed well. Presenting crude mortality rates with their 95% confidence intervals of predicted rates showed higher agreements among the three groups than using the rank or intervals of mortality rates defined by quartile in the hospital performance assessment. The crude mortality rates for the low-risk patients in 21 of the 23 hospitals were located on the same side of their 95% confidence intervals compared to that for all patients. High-risk patients and all patients differed at only one hospital. In conclusion, the impact of risk selection by hospital on the assessment results was the smallest when comparing the crude inpatient mortality rates of CABG patients with the 95% confidence intervals of predicted mortality rates. Given the increasing importance of quality improvements in Korean health policy, it will be necessary to use the appropriate method of releasing the hospital performance data to the public to minimize any unwanted impact such as risk-based hospital selection.

Objectives : To save the lives of patients with cardiac arrests, CPR must be performed rapidly and precisely. Regarding its critical necessity, there is a growing tendency to encourage whomever witnesses the cardiac arrest to perform basic CPR. However, the attitude toward basic CPR nor its current state of education in Korean Oriental Medical arena, which is one of the dual axes unique to Korean medical system, are not known. This is a kind of pilot study to research attitudes toward and the educative effect of basic CPR among oriental medical doctors in Korea. Methods : We carried out surveys and tests targeting nineteen apprentice doctors working in Dongguk University Ilsan Oriental Hospital, who were receiving training for 'AHA BLS course for healthcare providers', on the attitude toward and educative effect of basic CPR before and after the education. Results : The pre-educational survey showed that most of the participants felt the necessity to be trained in the BLS course, were not confident about performing CPR, and not well-acquainted with the whole process of performing CPR. After education, however, none of them responded with a lack of confidence to perform basic CPR, and the score of the confidence to perform basic CPR was significantly increased, too (from $2.05{\pm}0.71$ to $4.05{\pm}0.40$, n=19, p<0.001). Moreover, all of them answered they were satisfied with this BLS course, and it aroused their sense of responsibility as oriental medical doctors. All the participants passed the exam, and their average score for BLS scheme performance was $28.2{\pm}1.3$. Conclusions : It is necessary, in the future, to set up a management system for intensive, regular and continuous reeducation and expand the research on the perception and attitude targeting larger numbers and more multilevel groups of oriental medical doctors.

Basic nursing core skills are the essential skills required of nurses to effectively care for their patients. This study introduces an on-campus practicum using a mobile-based reflective journal, and attempts identify the challenges faced by students when performing core clinical nursing skills. The on-campus practicum was operated based on Kolb's experiential learning cycle. For each class, students used mobile devices to write an online reflective journal. Analyzing contents of the reflective log helped in identifying difficulties experienced in executing core skills, and classifying them in terms of knowledge, skill, and attitude. The level of difficulty, importance, and confidence in the core clinical nursing skills were also assessed. Students were found to be struggling with various aspects of performing core nursing skills, especially in the skill category. Students also showed a lack of confidence in items they perceived as "high" difficulty, such as IV injection and indwelling catheterization. Moreover, over 50% students considered IV injection and vital sign checking as the most important core clinical nursing skills. Our data suggests the necessity to develop various contents and apply instructional strategies to solve the core skills difficulties faced by nursing students, and to continuously generate evidence for the same.

The Korean Railroad Research Institute (KRRI) has developed the rubber tired AGT system (Model: K-AGT) between 1999 and 2005. The K-AGT is a light rail transit system does not require a driver and generally operates on an elevated railroad for transporting passengers. Accidents caused by driverless vehicles can severely affect social confidence, safety and economy therefore, it is very important to minimize the occurrences of such faults, and to accurately perform detailed maintenance tasks and thoroughly investigate the cause of any repeated failures. This research develops the web-based Preventive Maintenance (PM) system for the KAGT train system. The framework of the PM system is based on performing a reliability analysis and a failure mode effects analyses (FMEA) procedure on all the sub-systems in the K-AGT system. Out of the devices that have a low reliability, the high failure ranked devices are included high in the list for performing the overall maintenance plans. Through registration of historical failure data, the reliability indexes can be updated. Such a process is repeated continuously and can achieve very accurate predictions for device operational life times and failure rates. Therefore, this research describes the development of the overall PM system consists of a reliability analysis module, a failure mode effect analysis module, and maintenance request module.
Ten methods of the total two-phase pressure drop prediction based on five existing models and correlations have been examined for their accuracy and applicability to pressurized water reactor conditions. These methods were tested against 209 experimental data of local and bulk boiling conditions : Each correlations were evaluated for different ranges of pressure, mass velocity and Quality, and best performing models were identified for each data subsets. A computer code entitled 'K-TWOPD' has been developed to calculate the total two-phase pressure drop using the best performing existing correlations for a specific property range and a correction factor to compensate for the predicted error of the selected correlations. Assessment of this code shows that the present method fits all the available data within $\pm$11% at a 95% confidence level compared with $\pm$25%, for the existing correlations.

Purpose: This study was conducted to develop and test the effects of a coronavirus disease 2019 (COVID-19) education program for nursing students. Methods: This study used a non-equivalent control group pretest-posttest design. A total of 71 undergraduate nursing students who had completed a fundamental nursing course and were in their third or fourth year of university participated in this study (experimental group n=38, control group n=33). The COVID-19 education program was developed according to the stages of analysis, design, development, implementation, and evaluation. The program consisted of three weekly sessions that each lasted about two hours. The data were collected from February 26 to March 26, 2022 and were analyzed using the chi-squared, Fisher's exact, and independent t-tests. Results: Knowledge about COVID-19, knowledge about personal protective equipment and attitudes toward COVID-19 were not significantly different between the experimental and control groups. However, significant differences were found between the experimental and control groups regarding their confidence in COVID-19 patient nursing care (t=3.02, p=.004). Conclusion: It was confirmed that the developed program was effective in enhancing the confidence of nursing students in performing nursing for COVID-19. Therefore, it is proposed that the education program developed in this study be used as part of an infection control education program to improve nursing students' abilities to respond to emerging infectious diseases, including COVID-19.

This study is a pilot study to confirm the effectiveness of training after applying emergency simulation training for inactive nurses and to present a new model of simulation training operation method. In this study, the control group is a group that directly participates in the simulation activity, and the experimental group is the group that observes the control group's simulation activity. Experimental group and control group were matched 1:1 to experience all the roles of the resuscitation team. The study participants were 5 inactive nurses in the experimental group and 5 inactive nurses in the control group, and the total training time was 5 hours. The emergency simulation operation composition consists of theory education, skill education, and simulation. The interview was conducted. The educational satisfaction of the participants was 4.65 points for theory education and 4.70 points for practical education based on 5 points. Participants' performance confidence improved from 3.60 points before operation to 7.20 points after operation. Emergency simulation operation consisted of pre-test, theory education, skill education, simulation implementation, debriefing, and post-test. Participants expressed that the choice of group greatly reduced the burden and anxiety about performing the role of the resuscitation team. However, difficulties and inexperience in the operation of the defibrillator were reported in the experimental group. The control group reported that the simulation activity of the experimental group was not significantly different from theirs. Through the results of this study, it was confirmed that emergency simulation education not only reduced the burden and anxiety of inactive nurses, but also had an effect of education. Based on the research results, it is proposed to expand the participants and verify the effectiveness of education through specific variables such as learning commitment, learner confidence, simulation satisfaction, and team effectiveness.
