대한학교 예술-체육 계열 교과 통합 현황에 관한 사례 연구

박창헌,오은주 한국열린교육학회 2009 열린교육연구 Vol.17 No.4

The purpose of this study was to suggest the ways of facilitating curriculum integration among subject matters. This study focused on the analyzing art and physical education in alternative high schools. Fifteen out of 19 alternative registered schools in Korea participated in this study. In order to find out how alternative schools are currently involved in curriculum integration in terms of art and physical education, the school curriculum guide books were collected and analyzed. In addition, surveys and interviews were conducted with teachers in the participating schools. Eight teachers participated in the surveys and two teachers participated in the interviews. The results indicated that the teachers neither had much experiences in curriculum integration nor had the desires to integrate curriculum among the subject matters. Some teacher agreed that curriculum integration was beneficial to students in many ways, providing new experiences to them. Since most of teachers did not know the appropriate ways to integrate curriculum, there should be balance between subjects which they might not know how to handle. It appeared that curriculum integration experiences should be included in the teacher education. Suggestions for facilitating teachers to integrate curriculum in cooperation with other teachers were made 본 연구에서는 예·체능 계열 교육과정을 중심으로 대안학교 교육과정의 편성 및 교과통합의 현황을 분석해 교과통합 교육과정에 대한 여러 가지 가능성을 탐색하고 통합 교육과정 여건 조 성 방안을 탐구해 보고자 하였다. 총 15개 대안학교가 연구에 참여하였고 예·체능 계열 교과통 합 현황을 분석하기 위하여 참여 학교의 학교교육계획서를 분석하고 예·체능 계열 교사를 대 상으로 설문 조사와 개별 면담을 실시하였다. 연구결과 대안학교에서 3년 동안 이수해야할 총 이수학점은 평균 210학점이었고 예체능 과목에 할당된 평균 이수 학점은 30학점으로 총 교과의 14%를 차지하고 있었다. 예․체능 계열 교과목 담당 교원은 대학교나 교육기관으로부터 통합학 습에 대한 전문적인 교육을 받은 경험이 거의 없었다. 그러나 응답자 중 50%의 교사가 대안학 교에 재직하면서 통합 수업을 운영한 경험을 가지고 있었으며, 그 중 50%는 통합교과에 관심이 없거나 반대하는 입장을 보였다. 통합교과의 운영이 어려운 이유는 대부분의 교사들이 통합에 필요한 훈련을 받지 않았고 참고할 만한 통합 모델이 없기 때문에 교사들이 시도하기에는 어려 운 작업이라고 하였다. 아울러 간학문적 통합을 시도할 경우 어떤 학문에 우위를 두어야 할지가 문제로 대두되었고 팀티칭을 할 경우 각자의 영역을 강조할 것이기 때문에 진정한 의미의 통합 이 일어나기는 힘들다고 보고 있었다. 본 연구 결과로 학교 현장에서 통합학습 프로그램을 활성 화시키기 방안이 교사 조직, 학습 환경 및 학교의 지원 측면에 초점을 맞추어 논의되었다.

朴昌憲 제주한라대학 1988 論文集 Vol.12 No.-

Increased incidence of nosocomial opportunistic infections and infections due to antimicrobial resistant bacteria have been reported in recent years. Frequently isolated bacterial species may differ depending on the characteristics of hospital. The pattern of antimicrobial susceptibility may also differ depending on the usage of antimicrobial agents. In this study, pus culture results at the National Police Hospital, during January 1985 to December 1988 were analyzed. Also analyzed were the results of antimicrobial susceptibility tests. The following results were obtained. 1. Among the 761 isolates, 44.3 % were gram-positive bacteria and 55.7 % gram-negative bacilli. S. aureus was the most frequently isolated gram-positive bacteria (30.4 %) and Enterobacter Cloaceae the most frequently isolated gram-negative bacilli (11.4 %). 2. Slightly higher annual rate of isolation was noted for Enterobacter Cloaceae in 1987 and for S. aureus and Proteus mirabillis in 1988. 3. S. aureus showed the lowest isolation rate in September-October, and Enterobacter cloaceae the highest rate in May-Jun. 4. S. aureus was mare frequently isolated from outpatients and of E. cloaceae from inpatients. 5. Most of the S.aureus isolates were susceptible to cephalothin (84.0 %) and methicillin (76 %). 6. Most of the Enterobacteriaceae isolated were susceptible to amikacin, gentamycin, kanamycin, while many of them were resistant to ampicillin and tetracycline. 7. Only 39 % and 47 % of Pseudomonas isolate were susceptible to gentamicin and tobramycin.

Patients with fixed orthodontic appliances frequently have increased levels of plaque accumulation leading to the possibility of gingivitis or enamel decalcification. Although many methods may be helpful in reducing dental plaque formation, optimal mechanical removal of plaque is tile most important factor during orthodontic treatment. The porpose of this study was to evaluate the efficacy of'an electric toothbrush, with a specially designed orthodontic brush head. compared with a manual toothbrush in controlling plaque and gingivitis for patients with fixed orthodontic appliances. Oral hygiene status was measured in thirty four patients, using a plaquc index, a gingival index and a bleeding index. before and four weeks after attachment of fixed orthodontic appliances. Patients were randomly divided into two groups, the electric and the manual toothbrush groups. Oral hygiene instruction was given according to the type of toothbrush used. The Braun Oral-B D9511 with Braun Oral-B Ortho OD 15-1 brush head was used as the electric toothbrush while the Butler G.U. M 124 was given as the manual toothbrush. After 4 weeks and 8 weeks, oral hygiene status was measured again. Through the comparison berween the electric and the manual toothbrush grpups. following results were obtained. 1. All oral hygiene indices showed increasing tendency after 4weeks of fixed orthodontic appliances. 2. All indices presented decreasing tendency four and eight weeks after oral hygiene instruction. 3. In case of gingival index and bleeding index. decreasing tendency did not show a statistically significant difference between the electric and the manual toothbrush groups. 4. The decreasing tendency of plaque index presented statistically significant difference between the two groups. showing that the electric toothbrush was more effective in terms of oral hygiene. These findings suggest that an electric toothbrush is useful to the orthodontic patients with fixed appliances.

The Objectives of this paper were to develop a modified tank model that is capable of simulating daily streamflow from a small watershed using daily watershed evapotranspiration and to test the applicability of the model to different watersheds. Tank model was restructured to consist of three series of tanks, each of which may mathematically reflect watershed runoff mechanisms from different components of surface runoff, interflow, and baseflow. And pan evaporation was correlated to potential evapotranspiration estimated from a combination method, and was multiplied by monthly crop and landuse coefficients, and watershed storage coefficient to estimate the watershed evapotranspiration losses. Ten watersheds were selected to calibrate model parameters that were defined using an optimization scheme, and the results were correlated with watershed parameters. Simulated daily runoff was compared to the observed ones from the tested watersheds. The simulating results were in good agreement with the observed values when optimal and calibrated parameters were used. Ungaged conditions were also applied to compare simulated values to the observed. And the results were in fair conditions for all the tested watersheds which differ considerably in their sizes, landuse types, and physiological features.
