  • 본 연구의 목적은 실험 평가를 이용하여 탐구과정 기능을 측정하고, 인지 수준과 탐구과정 기능의 성취도와의 관계를 알아보는 것이다. 연구 대상은 인지 수준과 지역을 유층으로 하여 중학교 2학년 162명을 표집하였다. 실험 평가는 SISS에서 사용한 실험 과정기능검사 문항을 수정 보완한 산 염기, 밀도, 염화코발트의 성질에 관한 3가지 과제를 이용하여 순환 실험 형식으로 수행하였다. 탐구과정 기능은 D(계획), P(수행), R(추론) 등의 하위 기능을 포함한다. 실험 평가의 채점은 학생용 보고서를 이용하였으며, 5명의 평가자가 채점한 결과의 평균값으로 분석을 하였다. 연구의 결과 인지 수준이 발달함에 따라 탐구과정 기능의 전체 점수와 하위 기능인 D(계획), P(수행), R(추론)의 성취도가 모두 통계적으로 유의미하게 높아지는 것으로 나타났다. 그리고 인지 수준을 통제하고 탐구과정 기능의 성취도를 비교한 결과 지역간에 탐구과정 기능의 성취도 차이와 남녀간에 탐구과정 기능의 성취도 차이는 나타나지 않았다. 이러한 결과를 통해, 실험 평가를 통한 탐구과정 기능의 성취도는 인지 수준에 크게 영향을 받으므로 탐구과정 기능을 향상시키기 위해서는 학습자의 인지 수준을 고려하는 것이 매우 중요한 일임을 알 수 있다.

  • 연구의 배경 및 목적: 본 연구에서는 노인구강관리에 대한 산업체 수요기반의 교육과정을 개발하여 운영함으로써 노인치위생학 교육의 효과를 확인해 보고자 진행하였다. 연구방법: 산업체 수요기반 현장중심 실무교육에 따른 전공역량달성도, 노인치위생과정 인식, 수업만족도의 전후차이를 검증하기 위하여 비모수 분석으로 윌콕슨 부호순위 검정(Wilcoxon signed rank test)을 수행하였으며, 각 요인간의 연관성을 확인하기 위해 스피어만 상관분석(Spearman's correlation analysis)을 수행하였다(p<0.05). 결과: 전공역량달성도의 경우 산업체 수요기반 현장중심 실무교육을 수행 후 '노인과의 의사소통 역량'이 유의미하게 향상되었다(p=0.031). 고찰: 노인치위생학 교육과정은 산업체 현장에서 활용가능한 실무중심의 교육과정이 학습자에게 제공되었을 때 노인에 대한 실제적인 이해와 노인구강관리에 대한 현장실무전공역량이 더욱 개발될 수 있을 것으로 판단된다.

  • 본 연구에서는 과학수업의 실질적 개선을 위한 연구자-교사 협력모델(POCoM: Practical On-site Cooperation Model)을 확산시키기 위해 교사 연수 프로그램을 개발하고 적용하여 그 결과를 평가하였다. 연수프로그램은 다음 3가지 특성을 가지고 개발되었다 : (1) 실제 수업녹화 내용을 연수의 주요 소재로 활용한다, (2) 연구자와 교사, 교사와 교사간 활발한 의사소통과 의견교환을 강조한다, (3) 활동중심으로 진행한다. 9시간에 걸친 연수에는 17명의 교사가 자발적으로 참여하였다. 연수과정에서 교사들이 실시한 분석결과에 대해 분석 일치도를 구해 본 결과, KTOP(Korean Teaching Observation Protocol)을 이용하여 과학수업을 분석할 수 있는 교사 전문성이 향상된 것으로 나타났고, 교사들이 과학수업의 개선정도도 판단할 수 있음을 알 수 있었다. 설문지를 통해서는 다양한 측면에서 연수에 대한 긍정적 응답을 얻을 수 있었다. 또 연수 중 교사활동에 대한 관찰을 통해, 교사가 제기한 질문, 교사가 어려워하는 점, 교사가 제안한 개선의견 등을 분석하였고, 이러한 결과를 바탕으로 보다 좋은 연수가 되기 위해 고려할 측면들을 정리한 목록을 제안하였다. 이 목록이 앞으로 보다 효과적이고 의미있는 연수의 계획과 실행에 활용되기를 기대한다.

  • Korean reunification would be one of the greatest heaven-earth works by Gucheon Sangje in terms of the lasting paradise of the Later World. The Oseonwigi-gongsa describes what it will be around the Korean Peninsula. Furthermore, Haewon Sangsaeng is the very practical means in unifying the two Koreas. What are the effectiveness of Haewon Sangsaeng, regarding Korean reunification in dealing with the social science? This researcher has found out three main impacts as follows: (1) it deals deeply with the cause of the social conflicts, and it could provide the solutions towards the Later World, (2) it highlights the great values and the potential abilities of human, and (3) it widens the research areas up to the heave-earth-human Samgye. Dealing with Haewon Sangsaeng in the social science, researchers must consider the limit of the research, which are (1) the tenacity of researcher's goal and the extremity of the research, (2) the possibility of a fallacy in doing the social science, and (3) the paradox of knowledge. In conclusion, Haewon Sangsaeng has many fundamental and practical values when it comes to Korean reunification. First, it should be a very important virtue for the unification leadership and the Korean people. Second, it could heal the serious illness, rooted in the Korean War, and many internal conflicts between the right and the left ideologically. Finally, it also recover North Korean people's severe pain and grief under the long-term dictatorship, and the heterogeneity between the South and North Korean people for 60 years.

  • Optimal allocation of viewers on a terrain in such a wav that the hidden area would be minimized has many practical applications. However, it is impossible in practical sense to evaluate all the possible allocations. In this paper, we propose an optimal allocation of viewers based on genetic algorithm that enables probabilistic search of huge solution space. An experiment for one and three viewers was performed. The algorithm converges to good solutions. Especially, in one viewer case, the algorithm found the best solution.

  • The purpose of this study was to examine the factors related to satisfaction of users for the order communication system (OCS). The subjects of this study were 98 clerks at Chosun university hospital. The instruments used for this study were the conveniency and the practical application of the data developed by Lee, the satisfaction level developed by Sea Seang-mi and Kim in-sook. The data was analyzed by using the t-test, ANOVA, Pearson Correlation, Stepwise Multiple Regression with SPSS 10.0 program. The mean scores of the conveniency, the practical application of the data and the satisfaction level of user for the OCS was 3.28, 3.29 and 3.34, respectively. In general characteristics of the respondents, influencing factors to the perceived the conveniency of user for the OCS were gender, career and department. In general characteristics of the respondents, influencing factors to the perceived the practical application of the data of user for the OCS were department. In general, characteristics of the respondents, influencing factors to the perceived the satisfaction level of user for the OCS were gender, career and department. The correlation between the satisfaction level and the practical application of the data were statistically significant. The main factors influencing to the satisfaction level of user for the OCS were the practical application of the data (90.3%). In conclusion, The main factors influencing to the satisfaction level of user for the OCS were the practical application of the data. Therefore, it is recommended that guidebooks of user for the OCS or various OCS programs to promote the satisfaction level of user for the OCS and to improve the satisfaction level of user for the OCS should be developed.

  • Background: Hepatitis B is an important public health problem as one of the leading causes of morbidity and mortality. The aim of this study was to compare the theoretical and practical knowledge levels of dental assistant students about Hepatitis B Virus. Methods: The 1st and 2nd grade students of the Oral and Dental Health program were invited to participate in the survey. Out of the 68 invited students, 61 completed the questionnaire. The average ages of the male and female students surveyed were 20.27±1.45 and 19.56±1.16, respectively. A total of 34 questions were asked, of which 15 measured basic theoretical knowledge and 19 assessed basic practical knowledge. Results: There was no statistically significant difference between the students' knowledge for each question according to their sex and grade. When the questionnaire was grouped into basic theoretical and basic practical knowledge levels, both were observed to be high. While the lowest correct answer rate was 35.00% for the questions about practical applications, it was 31.14% for the questions measuring the level of theoretical knowledge. There was no statistically significant difference when the levels of knowledge of 1st and 2nd grade students were compared. Students answered the majority of the questions correctly, and ranged between 71% and 100%. Conclusion: Students' high level of basic theoretical knowledge can be a result of their in-class education on the fundamentals. However, their knowledge about the correct approaches in practical applications indicates the beneficial role of having well-defined criteria and prevention protocols that are required in hospitals and the effectiveness of their environmental orientations.
