Purpose : This study was conducted to identify the epidemiological characteristics of school accidents in middle school students. Methods : The subjects in this study were the students of a middle school in Gangnung. The study period was one semester, from March 2 to July 15, 1999. Data were collected by one of the authors using a structured questionnaire, and the subjects who had school accidents and visited the school health care office were interviewed. The data was analyzed using the SPSS and SAS programs. Results : The semester incidence rate per 100 students was 31.6 cases. The daily accident rate was 2.8 cases, and the accident incidence density was 2.6 cases per 1,000 students days. The mean of accident incidence was 1.7 per student. The incidence was the highest in June. The most frequent cause of accidents was carelessness, and the accidents were most frequent at recess. Conclusion : It is necessary to conduct the analytic epidemiological study to identify the risk factors of school accidents.

This paper is presented to prepare NGN quality assurance management process under the quality system test methodology. The process should be drawn for NGN quality measurement framework of multimedia traffic. NGN test bed management process model are QoS measurement metrics, measurement interval meter above, and measuring tools, measuring equipment, measurement methods and measurement results from a series of processes for the analysis and methodology. This model, NGN quality assurance activities should be utilized in the future. Quality target level only when themselves constantly measured and managed, does not guarantee the communication quality of service. It is sensitive to the importance of NGN network technology paradigm for research on quality management in the NGN. Key Words : Quality Assurance, Test Bed, Design,Next-generation Network

Impact of the oxygen functional group of nitric acid‑treated activated carbon on KOH activation reaction

Ji‑Hyun Kim,Sang Youp Hwang,Jung Eun Park,Gi Bbum Lee,Ho Kim,Seokhwi Kim,Bum Ui Hong 한국탄소학회 2019 Carbon Letters Vol.29 No.3

To prepare activated carbon with a high specific surface area, oxygen functional groups (OFGs) that can serve as useful electron donors during KOH activation were treated with nitric acid and incorporated into activated carbon. OFGs are incorporated differently according to the surface characteristics of starting materials. Up to 22.46% OFGs are incorporated into wood-based activated carbons (WACs), the C=O, COOH contents was 1.90, 17.05%, respectively. Whereas up to 12.82% OFGs are incorporated into coconut shell-based activated carbons, the C=O, COOH contents was 4.12, 6.15%, respectively. The OFGs used for increasing the specific surface area are the carbonyl group, and as the content of the functional group increases, the carbonyl group spreads to the carboxyl group. The specific surface area of activated carbons increased by 10–68% with an increase in the carbonyl group up to 6% (maximum point of carbonyl group). On the other hand, the specific surface area for WACs increased when the carboxyl group was 10% or below, but decreased by 6–15% when it increased to 10% or excess.

웹 기반 협동학습에서 다중지능이론에 의한 집단편성 방식이 자기주도학습능력과 학습동기에 미치는 효과

지상익,김성완,장윤정 연세대학교 교육연구소 2006 미래교육학연구 Vol.19 No.1

본 연구에서는 웹 기반 협동학습 환경에서 학습집단 편성방식이 학습자의 자기주도적 학습능력과 학습동기 변화에 어떤 영향을 미치는지 알아보고 지금까지 논의가 미흡했던 학습집단 편성 준거로서의 다중지능 이론의 적용 가능성을 탐색하였다. 연구 결과, 학업성취도에 근거하여 편성된 집단 중 동질집단 편성이 이질집단 편성보다 학습자의 자기주도적 학습능력과 학습동기에 더 효과적인 것으로 나타났다. 한편 다중지능에 근거하여 편성한 동질집단과 이질집단 모두 자기주도적 학습능력에 영향을 미치지 않았으나, 학습동기에 있어서는 이질집단 편성이 동일집단 편성보다 더 효과적인 것으로 나타났다. 본 연구를 통해 다중지능 이론의 학습집단 편성 근거로서의 적용 가능성이 직접적으로 확인되지는 않았으나, 기존의 학습집단 편성방식과의 비교 연구를 통해 집단편성의 새로운 준거 탐색을 위한 실험적 근거를 제공하는 기회가 될 수 있을 것이다. 또한 다중지능 이론의 교육적 활용에 대한 인식을 제고할 수 있을 것이다. The purpose of this study is to analyze the effect of group composition on self-directed learning ability and learning motivation in web-based cooperative learning and to search the applicability of multiple intelligence theory as the criteria of group composition. The findings of this research were as follows. In group composition based on the academic achievement, homogeneous group was more effective in self-directed learning ability and learning motivation than heterogeneous group. Group composition based on the multiple intelligence did not influence self-directed learning ability. However, in learning motivation heterogeneous group was more effective than homogeneous group. In conclusion, the applicability of multiple intelligence theory as the criteria of group composition was unconfirmed directly in this study. But this attempt of the applicability of multiple intelligence theory as the criteria of group composition can be considered to have significant meanings in exploring new learning strategies.

In this study, we have investigated potential energies of β-D glucopyranose in vacuum using QM and MM methods. In QM calculation, the local minimum geometries have been optimized in the level of B3LYP/6-311++G**. And we use AMBER package program and GLYCAM_06 force field for MM optimization. As a consequence, we confirm that GLYCAM_06 force field matched QM calculation roughly.

지연상,정상진 광주보건대학 1998 論文集 Vol.23 No.-

Ten of university hospitals in korea were sampled randomly, the average burden of a medical technician per a day is measured, the method which the appropriate number of medical technicians can be secured is sought, hospital scale and the number of patients are selected as variables, correlation to these variables is examined and it is to refer to estimate the appropriate number of medical technicians each hospital needed in future. As a result of this research, first in the number of medical technicians per 100 wards, radiographers are 4.5, clinical pathologists are 5.2 and physical therapists are 1.1. Second, it is examined and analyzed that the number of wards per one medical technician is not significant to the scale of hospital. Third, it is shown that in the number of patients per one medical technician at ten hospitals, radiographers are 30.5, clinical pathologists are 26.0 and physical therapists are 207.7. Fourth, in the average burden of one medical technician a day, radiographers are 23.3, clinical pathologists are 250.4 and physical therapists are 17.5 and in addition, it is analyzed that it has not significant relation to such variables as the average burden of a medical technician a day, the scale of hospital and the number of patients. Fifth, in the average hours of handling a service, it is examined that photographing takes 22.1 min., test 20 min and physical therapy 29.8 min. It is considered that the standard of appropriate number of medical technician which takes account of the number of patients, hours of handing a service and the speciality of hospital should be prepared in each hospital and improvement of quality of medical service should be emphasized.
