In order to enhance basic competencies for freshmen at engineering college, whose learning ability is gradually declining, a new course was developed to review basic mathematics and physics through a process of collecting opinions from fellow professors. Tests in six fields of math and physics with the same problems showed the correct answer rate rose from 24.8% at the beginning of the semester to 59.0% at the end of the semester after operating the course developed. According to the survey, the students' self-evaluated confidence on the basic competencies in 16 fields of math and physics showed a significant increase. Students with high confidence in basic competencies also received high actual grades. General high school graduates' confidence point in basic competencies improved from 54.7 at the beginning to 75.3 points at the end of the semester, while specialized high school graduates' enhanced from 38.3 to 64.0 which is higher than that of general high school graduates at the beginning of the semester.

Purpose: Safe sleep practices (SSP) are among the main strategies to reduce sleep-related sudden unexplained infant death (SUID). Daycare personnel must be knowledgeable and trained in SSP related to SUID. This study explored the experience, knowledge, and confidence regarding SSP associated with SUID of daycare personnel. Methods: A cross-sectional survey was conducted with 395 staff members at 61 daycare centers to measure their experience related to SSP (10 items), related to sleep position and location, bedding materials, and other topics; knowledge of SSP (18 items); and confidence in SSP (1 item) related to SUID. Results: A substantial proportion (23.6%) of respondents used the lateral or prone positions for infant sleep. On average, 4.5 bedding materials were used for infant sleep. Participants showed a lack of knowledge about SSP as indicated by a 56.6% knowledge of SSP related to SUID correct answer rate. Personnel who received SUID education were more knowledgeable and had more confidence regarding SSP than those who did not. More knowledge and confidence related to SSP were associated with better adherence to SSP. Conclusion: Standard SSP guidelines should be developed based on South Korea's culture of childcare for educating both childcare professionals and parents at home.

Objectives : The study examined mothers' oral health knowledge and oral health management behavior to their children that affect directly children's oral health to prepare basic aiming at children. Methods : Therefore, a survey of 235 mothers in 10 kindergartens located in Seoul was conducted by self-administered questionnaires. Results : As to mothers' oral health knowledge, the correct-answer rate for questions about tooth-decay was highest, and the level of 'middle (5-7 points)' was the most common with 50.0%. Regarding oral health knowledge according to mothers' general characteristics, the higher academic background and family's monthly earnings were, the higher oral health knowledge was. It showed a statistically significant difference(p<.01). In terms of mothers' oral health management behavior to their children, 79.1% of mothers who had the visiting experience in the dentist's for caries prevention was highest. As to the number of brushing, the twice was highest with 51.2%, and regarding brushing time 2min was highest52.6%. Also, the rate of using the fluoride toothpaste was 68.4%, and the rate of mothers who helped their children's brushing was 83.3%. As to the oral health management behavior to their children by mothers' oral health knowledge, mothers with higher oral health knowledge used the fluoride toothpaste showing that there was a significant difference(p<.01). Also, mothers with higher oral health knowledge helped more children's brushing, so that there was a significant difference(p<.05). Regarding the oral health management behavior to their children according to mothers' visiting experience in the dentist's, mothers who visited the dentist's during the recent one year had higher visiting experience of dentist's for children's caries prevention(p<.01) and longer time of brushing by 3min(p<.05), and helped their children's brushing a lot. The findings showed a significant difference(p<.001). Conclusions : As the results above, as mothers' oral health knowledge and oral health management behaviors to their children affect closely children's oral health, more systematic, specific and active oral health programs should be provided to mothers.

수 세기는 수 개념 및 연산과의 관련성으로 인해 수학 학습에서 기초적이면서도 중요한 위상을 차지한다. 특히 큰 수 세기는 수학 학습 초기의 수 개념 도입시 수 세기가 요구하는 일대일 대응이나 기수의 원리 등은 물론 자릿값의 이해를 포함하는 구조적 세기라는 점에서 핵심 학습 요소라 할 만하다. 본 연구는 현행 교과서 활동으로 구성되어 있지 않아 학생들의 경험이 전무할 것으로 예상되는 큰 수에 대한 수 세기 가능 여부 및 세기 전략을 파악하여 교수학적 시사점을 도출하는 것을 목적으로 한다. 이를 위해 세 자리 수까지 학습하였고 교과서 활동으로서 묶어 세기와 뛰어 세기를 경험한 초등학교 2학년 학생 89명을 대상으로 세 자리 수만큼의 대상이 불규칙적으로 배열된 그림에서 수 세기 및 세기 방법을 묻는 문항으로 구성된 검사지를 제공하였다. 학생 응답을 정오답률과 사용한 세기 전략 및 인지적 특징 측면에서 분석한 결과, 오답률이 매우 높고 십진 원리, 묶어 세기, 1씩 세기, 부분합 전략 등의 사용이 확인되었다. 이와 같은 분석 결과에 기초하여 교과서 활동으로서 큰 수 세기 활동을 포함할 필요성을 비롯한 몇 가지 교수학적 시사점을 도출하였다.

Purpose: As the interest and demand for esthetics grow up with medical development, the number of patients who want to correct dentofacial deformities by orthognathic surgery has increased. And the success of orthognathic surgery is dependent upon satisfaction of patients in great measure. Therefore the purpose of this study is to examine functional disability, sensory disturbance and esthetic satisfaction of the patients after orthognathic surgery. Material and methods: Among 89 patients who orthognathic surgery was performed at Seoul National University Bundang Hospital during the period from July 2003 to July 2008, 46 patients were considered in the study. Patients were surveyed with questionnaires and visual analogue scale(VAS) which author has designed. The analysis and comparison were performed according to gender, follow up span, and type of surgery based on answer of questionnaires. Results and conclusions: Total satisfaction rate was 76%. And there was statistical significant difference between subjective evaluation of facial esthetics before the surgery and that of after surgery(p<0.05). Differences in occurrence of functional disability, sensory disturbance between groups were not observed. In conclusion, the operator should understand the postoperative self-satisfaction of the patients and complications. If we can communicate with the patients before operation. patients' satisfaction rate will increase after operation.

Purpose: The purpose of this study was to survey the Coronavirus Disease 2019 (COVID-19) related knowledge, risk perception, preventive behaviors, depression, and anxiety levels among nursing students, and to identify factors that influence preventive behaviors. Methods: An online survey was conducted among nursing students from October 7, 2020 to October 12, 2020. The data were analyzed using independent t-test, one-way ANOVA, Pearson's correlation coefficients, and multiple regression. Results: A total of 222 nursing students participated in this study. The correct answer rate for COVID-19 knowledge was 90.0%, risk perception was 5.51±1.26, and the rate for preventive behaviors was 92.5%. The depression score was 6.28±4.63; 59.9% of nursing students had depression, and the anxiety score was 5.56±3.98; 59.9% of nursing students had anxiety. COVID-19 preventive behaviors had a positive correlation with COVID-19 knowledge (r= .30, p< .001), COVID-19 risk perception (r= .18, p= .009), and anxiety (r= .21, p= .001). Factors influencing COVID-19 preventive behaviors by multiple regression were identified as COVID-19 knowledge, anxiety, physical health status before and after COVID-19, grade, practical experience after COVID-19, and COVID-19 risk perception (F = 12.46, p< .001, R²= 25.8%). Conclusion: The results of this research on factors influencing COVID-19 prevention behaviors can be used in the future to develop appropriate health policies for individual and community infectious disease prevention behaviors.

The purpose of this study was to identify the level of HIV/AIDS related knowledge and attitudes of Korean childbering women. The subject were 1152 Korean women who were living in the Seoul area and whose age was between 17-50 years. Data was collected by self reporting with a questionnaire of 57 items developed by the researcher. The reliability of the instrument for the HIV/AIDS related knowledge and attitudes were Cronbach's alpha. .6954 and .7987 respectively. The results were as follows: The mean age of the subjects was 26 years and 46.8% of them were married. The mean score for HIV/AIDS related knowledge was 14.7 out of a possible maximum score of 22. The correct answer rate for HIV/AIDS related knowledge was between 87.0-94.1% for the risk factors. and 36.4-54.8% for the transmission mode. Even though 87% of the subjects knew that homosexuals are risk group for HIV/AIDS. only half(55.8%) of the subjects answered that anal sex is the transmission mode. And only 57% of the subjects knew that HIV/AIDS transmission is possible through heterosexual contact. Their agreement level for attitudes was in order of communal coping (95%). pregnant women protection (94%). Problem appraisal (82%). patients isolation(68%). and disclosure of infection(67%). It was shown that the group who had a pregnancy (t=2.07, p=.039), used contraceptives (t=2.57, p=.OO1). and the group of college level graduates(t=3.61, p=.000) had a higher level of HIV/AIDS related knowledge. The agreement level of pregnant women protection. patient isolation. and problem appraisal were higher in the group of having had a pregnancy, having used contraceptives. and the group over 30 years of age. It was concluded that Korean childbearing women were quite knowledgeable about the risk factors but confused about the transmission mode. especially heterosexual contact. and they showed responsive attitudes to the HIV/AIDS issues considering the 339 infected cases in Korea. They preferred isolation of patients and communal coping as behavioral attitudes. Therefore it can be suggested that a HIV/AIDS prevention program should be focused on transmission mode.
