The purpose of this study was to investigate the teachers' multi-media application ability, their perception on the use of multi-media for story-telling, and actual use in class. The survey, using a questionnaire, was conducted targeting 225 teachers in Seoul, Gyeonggi and Incheon. The results of the study are as follows: Firstly, teachers who were younger, had a higher level of education, were experienced in taking multi-media courses, and took charge of larger classes showed better ability of multi-media application. And teachers who were trained on multi media as well as kindergarten teachers indicated a more positive perception about applying multi-media for story-telling. In addition, teachers who had higher levels of education, were experienced in taking multi-media courses, and teaching larger classes at national/public institutions applied multi-media more frequently. Secondly, the teachers' ability of applying multi-media, their perception on the use of multi-media for story-telling, and their multi-media use in class indicated strong positive correlations. Thirdly, a teacher's perception on the significance of the multi-media application for story-telling, their skills for multi-media use, the size of classes, and the training experiences on multi-media affected their actual application of multi-media for story-telling.

This study analyzed the effect of the inclusion program executed in a social welfare institution for handicapped children of community in order to support inclusive education of elementary school. The statistical analyses adapted in this study were the Frequency Analysis, T-test, One-Way ANOVA, Correlation Analysis, Two-Way ANOVA, and ANCOVA. As the results of the analyses, there was significant difference of the increase in the scores between pre-test attitude and attitude improvement of normal children (nonhandicapped children) by intervention of the inclusion program. Secondly three variables such as the sex, the experience of integrated class, and the school environment gave influence on attitude improvement of normal children, but two variables such as the school year and the religion didn't give influence on attitude improvement of normal children. However, as the results of the ANCOVA, it was appeared that both the school year variable and the religion variable didn't give influence on attitude improvement of normal children. Consequently, as the attitude improvement of normal children was irrelevant to the characteristic variables such as the school year and the religion, it is verified that the inclusion program gives still significant impact in the difference between pre-test attitude and attitude improvement of normal children. In conclusion, As the pure effectiveness of the inclusion program executed in social welfare institutions for handicapped children in order to support inclusive education of elementary school was confirmed, it was suggested in this study that the inclusion program in the field of social work practice based community can be an important tool of social integration through inclusive education between handicapped children and normal children.

Approximately 100 drugs have been reported to affect the lungs adversely. Among these, pulmonary toxicity caused by antieneoplastic agent. is being recognized more frequently. Cyclophosphamide is an immunosuppressive alkylating agent used for the treatment of a wide variety of malignant and nonmalignant diseases. The incidence of pulmonary toxicity is probably less than 1 percent The first case was reported in 1967. Since then, more than 20 well-documented cases of pulmonary toxicity associated with cyclophosphamide have been reported in the literature. In Korea, three patients were identified with cyclophosphamide-induced lung disease. The typical features of toxicity include dyspnea, fever, cough, new parenchymal infiltrates, gas exchangs abnormalities on pulmonary function tests, and pleural thickening on chest roentgenogram. The best approach to management is early diagnosis, discontinuation of the offending drug and administration of corticosteroid therapy. Recently, we experienced a case of diffuse alveolar damage induced by cyclophosphamide. The patient presented with early-onset pulmonary toxicity and died of repiratory failure despite early use of corticosteroid.

Drug resistance of M. tuberculosis has been investigated with isolates from patients screened out of the sample population of the nationwide tuberculosis prevalence surveys or from the routine cultures. The results showed a close inverse relationship between prevalence of drug resistance and efficiency of the past or current treatment regimens of NTP. Individual drug resistance also showed a close relationship with the extent of use of the relevant drugs. Drug resistance was found in 38.0% of M. tuberculosis isolates from patients found in 1965 survey and remained unchanged until it increased upto 48.0% in 1980 survey. The resistance prevalence, however, dropped to 30.8% in 1985 and further to 25.3% in 1990 survey. Such decrease was fairly well coincided with a continuous increase of the treatment efficiency (from 60% in 1984 to 77% in 1989) in 1980s. Initial drug resistance also showed a similar trend, namely 26.2% in 1965, 23.9% in 1970, 20.1% in 1975, 30.6% in 1980, 17.4% in 1985, and 15.0% in 1990. The similar figures were observed in M. tuberculosis isolates from patients diagnosed in the routine services. Higher prevalence of initial drug resistance was observed among urban patients than rural patients and among young patients than old patients. These findings signify that a continuous survey on drug resistance permits to monitor efficiency of treatment programme of the country.

In this case study, we investigated the characteristics of pre-service secondary science teachers' curriculum design for teaching in science museums. Three pre-service secondary science teachers at a college of education in Seoul participated in this study. We have observed and recorded their teaching practices in science museums, collected all of their teaching materials, and conducted semi-structured interviews before and after teaching. All the data collected were analyzed by using the constant comparative method. The analyses of results revealed that the pre-service teachers structured their teaching in a series of pre-visit, during-visit, and post-visit as continuous activities. They attempted to reinforce students' learning experiences during the visit by providing post-visit activities, and also properly considered the principle that activity should be personally meaningful or relevant to students. However, they lacked the perceptions as well as the practical knowledge of reducing student's novelty of the science museum by providing activities prior to the visit, encouraging to engage in joint productive activities, promoting diverse social interactions, and providing students with choices and controls on their learning. On the bases of these results, we made some suggestions in pre-service teacher education for the professional development of teaching in science museum.

The purpose of this study was to apply the microgenetic analysis method for development of information on an individual's change in a certain area during a consistent time period to seek change in scientific questions that elementary school students create. The study subjects were six 6th graders in I elementary school located in Kyunggido with the students conducting 6 sessions of two observational tasks about dry grapes contained in soda pop and candlelight. Information were collected through students' scientific question development paper, record of field observation and interviews. The results of this study are as follows: first, the number of scientific questions that the elementary school students developed showed a tendency for reduction; second, the changes in type of scientific questions bring different results, which depend on a particular characteristic of the tasks; third, By observing pattern changes in scientific questions of each individual, it was found that different results show for each time for the same task, which in other words means that there exists variability within an individual. Also, variability between individuals were shown by confirming that the change pattern for each person were diverse. Thus, the result of this study shows the following implications on education of scientific question development. For students, scientific question development mean more opportunities to increase the process of developing and acquiring knowledge. Therefore, it is important to create situations where one can come up with scientific questions. In addition, analysis in tasks' nature when selecting tasks would be necessary to develop diverse scientific questions.

This study analyzed some of the discrepancies in quantitative and qualitative data focusing on cognitive and affective achievement in science education. Academic and affective achievement score of 308 high school students were collected as quantitative data, and 33 students were interviewed for qualitative data. We examined the causes and types of discrepancies in terms of testing tools. As a result from quantitative data, there were a large number of students with a big difference between subjects in cognitive achievement, and constructs in affective achievement. More than 20% of the students did not match tendency between achievements in two areas. Through interviews, some examples such as intentional control of science learning for future study and careers, different responses by differences in perception between school science and science, appeared. A comparison of quantitative data by testing tool between qualitative ones and interviews showed conflicting result, where most students evaluated themselves differently from their own quantitative data. That is due to the students' interaction with the testing tools. Two types of discrepancy related to testing tool are found. One is 'the concept difference between the item developer and students,' the other is 'the difference between students' exposed response and their real mindset.' These are related to the ambiguity of the terms used in the tool and response bias due to various causes. Based on this study, an effort is required to elaborate the testing item that matches students' actual perception and to apply students' science learning experience to testing items.

The main purposes of this study are to describe the elderly dementia, and to explore characteristics of the elderly dementia among the aged 65 and over in Daegu area. In this study, 1,120 subjects which were 0.6 percent of the population were selected and face-to-face interviews were conducted. The face-to-face interviews were conducted from July 1, 2004 to August 31, 2004. KMMSE was introduced to measure the status of the interviewees' dementia. The findings of this study are as follows: 8.9 percent of respondents turns out to be dementia patients. Among the dementia patients, 52.5 percent are mild dementia patients, 35.0 percent are mid-level symptoms and 12.5 percent are severe symptoms of dementia patients. Cross-tabulation analyses and logistic regression analysis were introduced to explore the demographic, living, and behavioral differentials of the elderly's dementia. According to the logistic regression analysis, it turns out that white educational attainment, participating in the leisure activities for both physical exercise and mental activities, having meals regularly, adequate amount of meals, and high economic status decrease the odds ratio of elder dementia among the elderly who are 65 and above in Daegu area and are statistically significant. On the other hand, age increases the odds ratio of the elder dementia of the elder among Koreans above 65 in Daegu area. Finally, policy implications and some suggestions for the improvement of the elder dementia are introduced and discussed.

Component-based software development is introduced as a new development paradigm in software development method. This approach is different from existing software development approach because it is based on reusable and autonomous unit, component. Therefore, component-based development(CBD)is divided into two stages; component development process and component assembly process; application development process. Component development process is the core of CBD because component has a key for good software. Currently many methodologies or tools have been introduced by various academies or industries. However, those don't suggest systematic and flexible modeling techniques adaptable easily into component development project. Existing approaches have a unique orarbitrary modeling technique or provide heuristic guidelines for component modeling. As a result, many component developers are faced with a difficult problems; how to developcomponent models, when develop which diagrams, and so on. In order to address this problem, we suggest a meta-model driven approach for component development in this paper. We provide meta-models according to both layer and development phase. We expect that suggested meta-models allow component developers to develop appropriate models of the time.

국내에는 약 14,000개의 중 소규모의 저수지들이 있다. 최근에 이상기후로 인한 많은 강우가 발생하여 저수지들의 월류나 파이핑으로 인한 붕괴가 지속적으로 일어나고 있어 많은 인명 및 재산피해가 발생하고 있다. 특히 설계홍수량을 초과하는 월류로 인한 댐 붕괴 발생 시 피해규모가 크기 때문에 전국적으로 본포되어 있는 저수지들의 설계홍수량을 시급히 파악하여 저수지의 수문학적 안전성을 판단하고 설계홍수량이 작은 저수지의 경우 별도로 관리 할 수 있어야 한다. 하지만 기존에 저수지의 안전여부를 판단 할 수 있는 댐 붕괴 모의의 경우 많은 시간과 노력이 요구 되어 저수지의 안전여부를 보다 쉽고 빠르게 판단 할 수 있는 기준 마련이 시급히 필요하다. 본 연구에서는 보다 쉽고 빠르게 소규모저수지의 수문학적 안전성 평가를 할 수 있는 간편법에 대하여 연구 하였다. 연구 방법은 HEC-HMS을 이용한 댐 붕괴와 본 연구에서 제시한 간편법을 통하여 홍수량의 비교 검토 및 저수지의 수문학적 안전성을 평가를 하였다. HEC-HMS의 첨두홍수량은 빈도별 지속시간별 확률강우량을 이용하여 산정하였으며, 가능최대홍수량(PMF)은 실제호우전이법으로 산정한 가능최대강수량(PMP)을 이용하였다. 간편법의 첨두홍수량은 합리식과 통합형 강우강도식을 이용하여 산정하였고, 가능최대홍수량(PMF)은 Creager공식을 이용하여 산1)정하였다. 댐 붕괴의 경우 HEC-HMS에서는 댐 붕괴 모듈을 실행하여 모의를 하였고, 간편법의 댐 붕괴는 여수로의 한계 유출을 파악할 수 있는 위어공식을 이용하여 댐 붕괴 모의를 하였다. 마지막으로 산정된 첨두홍수량과 가능최대홍수량(PMF)을 작성된 수문학적 안전성 평가표에 기입하여 비교 분석하였다. 연구결과 HEC-HMS로 산정한 빈도별 첨두홍수량 가능최대홍수량(PMF)과 간편법으로 구한 빈도별 첨두 홍수량 가능최대홍수량(PMF)의 차이는 약 편차가 50%정도로 간편법으로 구한 첨두홍수량 가능최대홍수량(PMF)이 더 크게 산정되었다. 편차의 발생 이유는 본 연구에서 제시한 간편법의 경우 안전율을 고려한 경험공식을 사용하였기 때문이라고 판단되며, 간편법을 통한 소규모저수지의 수문학적 안전성 평가를 다른 대상지역의 소규모저수지에도 적용하여 보고 수문학적 평가방법이 올바르게 적용 될 수 있는지 확인이 필요하다고 판단된다.
