Although there have been many studies in the accident proneness, little attention appears to have been given to the part possibly played by menstruation. In some previous studies of menstrual disorders, it was observed that the reaction time was slow and the judgement impaired during the premenstrual period. As both judgement and reaction time are important factors in the avoidance of accidents, it was felt that a study of women involved in accidents might reveal a correlation between accident and menstruation. The author surveyed menstrual cycle of 90 patients with accidents who visited Han Gang Sacred Heart Hospital from 1st June 1979... to 31st Aug. 1980. In order to determine the phase in which they met the accidents and to explore the correlation between accident and menstruation, the menstruation cycle of 28 days was divided into seven, 4-day periods by Dalton's method. The results were as follows: The accidents of 90 patients were found to have ocurred most frequently during menstrual period(18.9%), followed by the period of the 5th day through the 8th day (16.7%), mid-cycle period (16.7%), and premenstrual period (16.7%). A total of 35.6% of the patients had accidents during menstrual and premenstrual period. The author, therefore, suggested that there was a relationship between the phases of the menstrual cycle and accidents.

This trestise analyzes the deaf student's capacity in use of postposition by comparing with that of normal student. Their issue contents are can be summarized into the following two points. 1.In their frequency of the use of postposition, both deaf-students and normal students have a aqual post position. But in the misuse of those deaf student's postposition is high particulary until the students of middle school, the postposition of misuse does not decrease and aqual to that of students of elelmentary school, but up to the student of high school in minute decrease. Thus we can define that deaf student's composition ability is low in quality when compared with that of normal students. 2.the analysis of deaf student's misuse of postposition shows that the misuse of adjective postposition most frequently arises, and that of subjective postposition, postposition omission, postposition addition, objective postposition are following successively. On the contarary, the misuses of indeclinable adjective postposition, descriptive postposition, subsidiary postposition are more appear in students of milddle and high school.

최석진,남상준,류재명,손용택,이동엽 한국사회과교육연구회 2000 사회과교육 Vol.- No.33

이 연구는 남북한 통일을 대비하여 북한 고등중학교 지리 교육과정 및 교과서를 비교·분석한 것이다. 남북한의 학제와 지리과 영역의 교육과정상의 위치가 다르고 북한의 교육과정을 입수할 수 없었기 때문에, 입수한 북한의 고등중학교 1학년부터 5학년의 지리교과서 5종(1991년도부터 1993년도 발행분)을 대상으로 분석하여, 남한 6차 교육과정의 중학교 사회와 고등학교 공통사회(한국지리) 및 세계지리 내용을 비교 분석하였다. 연구 결과는 다음과 같다. 첫째, 남북한 중등학교 지리교육은 교육과정상의 편제에서 북한은 고등중학교 전학년에 걸쳐서 지리가 독립과목으로 편제되어 있으나, 남한은 중학교 사회과에 통합되어 있고, 고등학교에서는 공통사회에 포함되었으며 세계지리가 선택과목으로 되어있는 등 지리교육 내용계열과 조직체계도 차이가 난다. 둘째, 지리 교육의 이념과 목표에서, 남한은 민주시민 양성을 목표로 하여 개인의 지리교육적 성취가 주된 것이나, 북한은 집단 구성원으로서의 개인 양성에 중점을 두고 있다. 이러한 차이점은 정치체제의 차이에서 비롯된 것이며 지리교육 내용의 구성과 강조점등에서 많은 차이점을 나타내게 하고 있다. 셋째, 지리교육 내용 구성과 서술 등에 차이가 있다. 국토지리와 세계지리 및 계통지리와 지지의 배열과 비중 등이 다르며, 내용의 서술에서도 차이점을 볼 수 있다. 특히, 북한에서는 국토지리와 자연지리의 비중이 높으며, 주요 개념과 용어 설명에서 남한과 다른 점이 보인다. 넷째, 교과서의 구성과 교수-학습 방법 및 자료 사용에서 차이점이 보인다. 북한에서는 실습, 실험 등이 강조되면서 실제적인 기능 향상에 많은 비중을 두고 있으며, 사진에 비해서 그림을 사용하는 삽화의 비중이 높다. 교과서의 외형적 체제와 지질 등에서 차이가 큰데, 이 점은 경제력의 차이에서 비롯된다. 본 연구 결과 남북한은 모두 지리교육을 중등학교에서 중요시하고 있으며, 지리교육을 통하여 소기의 목표 달성에 노력하고 있으나, 서로간에 상당한 차이점도 발견할 수 있었다. The purpose of this study is to understand the similarity and differences of the geography textbook between north and south Korea in preparation for the unification. Five geography textbooks for the first through fifth grade in secondary school were used in the analysis of the geography curriculum for secondary schools in North Korea. The major findings of the study are as follows: First, South Korea takes an integration approach to teach geography as part of the social studies education whereas North Korea treats geography as an independent subject throughout secondary school. Second, South Korea aims at nurturing democratic citizen, emphasizing individual achievement, whereas North Korea puts emphasize nurturing citizenship within community. Third, difference is noted in the organization and content of the geography curriculum between the two Koreas. North Korea puts more emphasis on national geography and natural geography than does South Korea. Forth, North Korean textbook is different from that of South Korea in that the former emphasizes on performance skills through hands-on practice and training. Also North Korean textbook uses more drawings than pictures. Despite differences in various aspects of curriculum and textbooks, there are a great deal of overlap in essential concepts and contents covered in two Koreas' geography textbooks. Both Koreas value geography education in the secondary schools and make efforts to fulfil the educational objectives in geography.

This study is to derive the rainfall intensity formula based on the representative probability distribution of Kumi city in Korea. The 9 probability distributions which have been widely used in hydrologic frequency analysis are applied to the annual maximum rainfall. The parameters of each probability distribution are estimated by method of moments(MOM), maximum likehood method(MLE) and method of probability weighted moments(PWM). The estimated parameters were checked by parameter validity conditions of each assumed probability distribution. Four tests which are χ2-test, Kolmogorov-Smirnov test, Cramer von Mises test and PPCC test are used in this study to determine the goodness of fit of the distributions. The Gumbel distribution was determined as the representative probability distribution in Kumi city. Rainfall intensity formula was determined by linearization technique for the selected return periods.

A successful therapy of community-acquired pneumonia requires appropriate empirical antimicrobial therapy. Etiology and antimicrobial susceptibility of major pathogens of pneumonia can differ by country. Therefore, an ideal treatment guideline of community-acquired pneumonia should be based on the studies performed in each country. We developed a treatment guideline for community-acquired pneumonia in immunocompetent adults in Korea. This guideline was developed by the joint committee of the Korean Society for Chemotherapy, the Korean Society of Infectious Diseases, and the Korean Academy of Tuberculosis and Respiratory diseases.

We imported technology from abroad and studied grid connected type wind power generation owing to the lack of technology, but nowadays we conduct researches in many quarters because of national supporting policy. However, the research speed is delayed by burden for research expense which wind power generation is huge. Therefore, in order to experiment on various kinds of the wind turbine, generator, and converter easily, the development of wind power system is demanded powerfully among research workers. In this paper, in order to satisfy this need, I suppose a new simulation development environment. The electric power generated by wind is changing, so by using the converter, schedule electric power must be provided. Therefore, in this paper, I explained an element of the converter of the wind power generation system by showing two examples. First, Diode rectifier and current controlled voltage source inverter by using IGBT(Insulated Gate Bipolar Transistor) element was used in the wind power generation system. Second, rectifier for control by using IGBT and current controlled voltage source inverter by using IGBT element was connected the grid. Simulation for two examples of grid connected type wind power generation system uses PSCAD/EMTDC and analyzed the result.

In spite of labor saving in rice cultivation, the main factors preventing the enlargement of the direct wet seeding culture are unstable seedling establishment and greater susceptibility to lodging. In order to solve these problems, developed rice-seed pellets were investigated on sowing and early growth characteristics of seed pellet. Seed shifting, flooding seedling, and lodging of seeding percentage of pellet seed were lover than pregerminated or dry seed. Soil thickness covering seed of pellet seed was 2 ㎜ and shifting width of seed of that was 1.5 ㎝. Establishment percentage of pellet seed was the highest in 0 ㎝ of seeding depth. Early plant height, root length, number of leaf and root of pellet seed with seeding time were similar to those of dry seed.
