The purpose of this study was to describe elementary school students' health communication needs based on school-based health fairs by students' demographic characteristics and school health education experiences. A self-administered survey was conducted to a total of 851 fifth-grade students in 8 elementary schools in Seoul. For survey participant sampling, Seoul area was divided into four districts: north, south, east, and west, and two elementary schools were selected from each district by the stratified convenient sampling process. Three class 5th-grade students in each selected school finished the survey. Questionnaires and survey instruction letters were delivered to vice-principals in the designated schools and the vice-principals managed the survey process. The survey Questionnaire included demographic characteristics (sex, parent's marital status, parents' educational status, famil financial status, the person whom was with after school, and daily computer hour), health education experiences (health education at school, and school health education satisfaction), and health communication types. The health communication types were reorganized into eight types based on comprehensive literature review on health fairs (or child and adolescence. The health communication types were 'health exam and advice fair,''health promotion advertising and campaign,' 'health-related exhibition and experience fair,' 'profession visit-in-school education,' 'health-related VCR or movie festival,' 'health-related institute visits,' 'internet health counseling,' and 'telephone health counseling.' Regarding demographic characteristics, sex, family financial status, and academic performance were significant factors related to health communication need scores (p <.05). Girl, high level of family financial status, and excellent academic performance score were related to high score of health communication need. In terms of school health education experience, taking regular class for health education and satisfaction with school health education were linked to higher health communication need scores. This result discusses that experience and satisfaction with school health education largely contribute to building participants' health communication concepts and needs.

Purpose: In Korea, the working-hour limitation regulation has been implemented in December 2017. We aimed to define the difference in operative experience of surgical residents before and after implementing this policy in 2 hospitals among 8 affiliated hospitals of the Catholic Medical Center where implemented the 80 working-hour limitation policy since March 2015. Methods: All the operation records were reviewed, and the number of resident-participated surgeries between March and August in 2002 and 2017 were compared. Operations performed or participated in by residents as first assistants were defined as resident participated surgery. Results: After 2 years from the initiation of the resident work-hour limitations, the number of resident participated surgery has slightly decreased in both hospitals (Yeouido St. Mary's Hospital [YSM]: 317 to 302, St. Paul Hospital [SPH]: 635 to 461). For each resident, changes were like followings: $0{\rightarrow}21$ cases for R1, $65{\rightarrow}72$ cases for R2, $83{\rightarrow}192$ cases for R3, and $169{\rightarrow}17$ cases for R4 in YSM. In SPH, number of resident participating surgery was changed like followings: $4{\rightarrow}32$ cases for R1, $222{\rightarrow}100$ cases for R2, $317{\rightarrow}300$ cases for R3, and $92{\rightarrow}29$ cases for R4. In both hospital, while, total number of resident participating oncologic surgery has been decreased, number of resident participating appendectomy has been far increased. Activity of each grade resident is different according to hospital. Conclusion: Although total number of resident participating surgery decreased, variable changes were observed in each grade of resident according to each type of surgery and different hospitals. It is believed that comparisons of experiences from more hospitals in the future would be helpful in establishing the guidelines for surgical experience requirement of residents in Korea.

Background: Injury is the leading cause of death or disability in children and adolescents. Rates of deaths from injuries have recently declined, but studies of the occurrence of nonfatal injuries are lacking. Purpose: This study aimed to investigate nonfatal injuries in children and adolescents younger than 20 years based on data from the Korean National Health and Nutrition Survey, 2007-2018. Methods: A questionnaire survey was conducted to determine whether children and adolescents had experienced an injury requiring a hospital visit in the previous year. We investigated each injury's risk factors and characteristics. Results: Of a total of 21,598 children and adolescents, 1,748 (weighted percentage, 8.1%) experienced one or more injuries in the previous year. There was no yearly difference in the proportion of injuries experienced. Among the male subjects, 10.0% had an injury experience; among the female participants, 6.1% had an injury experience (P<0.001). The highest rate was 9.0% in children aged 1-4 years. In multivariate logistic regression analysis, male sex; having an urban residence; having restricted activity due to visual, hearing, or developmental impairment; and attention deficit/hyperactivity disorder were significant risk factors for injury experience. The characteristics of up to 3 injuries per patient were investigated, and 1,951 injuries were analyzed. Falls and slips accounted for 34.9%, collisions for 34.1%, and motor vehicle accidents for 11.3% of the total injuries. Ninety-six percent of injuries were unintentional, 20% caused school absences, and 10% required hospitalization. Conclusion: Among Korean children and adolescents, 8.1% experienced injuries at least once a year with no significant differences in incidence over the past 12 years. Greater attention and effort to prevent injuries are needed.

The aim of this study was to evaluate the competency of the Easyperio test, a genetic test method based on real time PCR for the detection of bacteria that cause dental caries and periodontal disease. To verify the validity of this text, various dental health evaluations were administered to 33 boys between the ages of 12 to 14, as this age group commonly experiences dental caries. These evaluations included a dental caries experience survey, a first molar health evaluation, the Dentocult Streptococcus mutans (SM) strip mutans, the Dentocult Lactobacillus spp (LB) test, and the Easyperio test. The correlation coefficients between the level of the Dentocult SM strip mutans and the dental caries experience were DT (R=0.570, p=0.001), DMFT (R=0.376, p=0.031), and first molar health (R=-0.395, p=0.023). The correlation coefficients between the amount of SM in the Easyperio test and dental caries experience were DT (R=0.528, p=0.002), DMFT (R=0.369, p=0.035), and first molar health (R=-0.426, p=0.013). The correlation coefficients between the level of the dentocult SM strip mutans and the SM amounts of the Easyperio test were S.mi (R=0.564 p=0.001) and S.mu (R=0.621, p=0.002). The correlation coefficients between the level of the Dentocult LB test and the SM amount of Easyperio test was S.mi (R=0.495, p=0.003). In conclusion, Easyperio test may be an easy and effective method for the differentiation and diagnosis of dental caries through quantitative and qualitative analysis of oral bacteria.

It is important to understand how pre-service teachers perceive e-learning because their prior-experience with e-learning will have a great impact on their teaching after the graduation. Pre-service teachers (401 students) with cyber learning experience, which is a form of e-learning, were selected in 2004 in May and June. Survey was conducted regarding the instructional experience (working hours, tasks and evaluation, satisfaction about cyber learning and its academic achievement, difficulties and suggestions) and instructional methods (instructional activities, frequencies of interaction, strategies of interaction, collaborative activities, behaviors in the group instructional activities for knowledge development). The results are pre-service teachers tent to spend similar v slightly less working hours for cyber learning, similar or slightly less satisfaction level for the instruction and the academic achievement. It was interesting that female students were more negative than males students, considering female students have been more active in online discussion traditionally. Logical presentation of contents and instructional strategies for the cyber learning were the most wanting suggestions. E-mails and BBS for reference materials were the two most used functions in the online learning. The amount and types of tasks were satisfactory. Students did not interact freely during the group activities, they reported they did not learn much through the group activity. During the group work, they consider they do their roles with responsibility while they have slightly negative responses toward other members' contribution in the group activity. Off line meeting is strongly suggested.

The purpose of this study was to investigate beginning earth science teachers' perceptions about Learning in Geologic Field Trip. The hundred and sixteen high school earth science teachers who were in the training for their promotion answered the questionnaire of Learning in Geologic Field Trip. It was divided into five parts: needs and educational values, teachers' experiences and their difficulties, and desirable teaching methods of Learning in Geologic Field Trip. Results indicated that the participants perceived Learning in Geologic Field Trip important in earth science education and responded positively to the educational values of Learning in Geologic Field Trip. Most of the beginning teachers had experience of geologic field trip, but did not learn how to teach it to their students during the geologic field trip in the pre-service training program. It was shown that only a few teachers had experience of geologic field trip and of teaching students in the outdoor of geologic fields after they became a classroom teacher. Most of the participants perceived that teaching students about the geologic field trip is difficult because of lack of their experience. In order to overcome the difficulty, teachers suggested that they need to learn how to teach the geologic field trip to students through their in-service training. leachers suggested that a desirable teaching method of the geologic field trip is to provide teachers with a teacher's manual including geological explanation and information about field trip sites before their visit so that they can scaffold it and facilitate the students' cooperative group activity during the field trip. As a follow up activity, the participants agreed that the presentation and discussion about the results should concur.
