It has been hypothesized that jobs that have both high psychological demands and low decision latitude("job strain") can lead to musculoskeletal disorder. The objective of this study was to test whether job strain was correlated with the presence of work-related musculoskeletal disorder, especially myofascial pain syndrome(MPS). Information on demographic factors, confounders such as household load and taking care of children or not, and scores for decision latitude, job demand, and social support was obtained by self-administered questionnaire, which had been developed in Korean language, by adopting NIOSH instrument and Extended Karasek Model(16 items). All subjects were also examined by rehabilitation medicine specialists for musculoskeletal disorders. Subjects(n=370) could be categorized into 4 groups, these were, housewives(n=89), shipyard CAD workers(n=89), general female workers(n=79; nurses, insurance counselors, public officials, clerks, etc), and telephone directory assistance operators(n=113). Results from univariate analyses indicated that all demographic factors, all confounders, scores for decision latitude and social support were not associated with the risk of musculoskeletal disorder. However, score for job demand was higher in musculoskeletal disorder cases than others. In subgroup analysis, this association was convinced again, in telephone directory assistance operators. Job strain model showed that the group of telephone directory assistance operators was high-stain group, and OR of musculo skeletal disorder was 2.446(95% C. I. : 1.174, 5.096), when comparing this with the low strain group. In conclusion, job strain is a risk factor for work-related musculoskeletal disorder.

과학탐구능력 향상을 위한 웹 활용 수업의 설계 및 적용

백남영,이희순 인천교육대학교 과학교육연구소 2003 과학교육논총 Vol.15 No.-

웹을 활용한 수업은 웹을 통해 학습자가 정보를 스스로 찾고, 판단하여 학습하게 하는 활동으로 자기주도적인 학습을 할 수 있게 하고, 다른 학생, 교사, 전문가와 상호작용을 할 수 있게 하여 협동학습을 가능하게 한다. 이러한 많은 장점이 있음에도 불구하고, 기존의 웹 활용 수업이나 연구는 단순히 홈페이지 중심으로 한 학습내용의 제시로 그쳐 웹의 효과적인 상호작용적인 측면을 간과한 내용들이 많다. 또 과학과에 그 효용 정도를 살펴보는 연구에서는 과학탐구능력의 향상 정도를 살펴보기보다는 과학관련 태도, 흥미의 변화 정도를 살펴보는 연구로 그쳤다. 이에 본 연구에서는 과학탐구능력을 향상시킬 수 있는 상호작용적인 웹 활용 수업을 설계하고, 본 연구자가 설계한 웹 활용 수업이 과학탐구능력에 미치는 효과를 알아보고자 하였다. 연구자가 웹 활용 수업을 설계하면서 가장 중요시 여긴 것은 두 가지이다. 한 가지는 웹의 상호작용성을 얼마나 잘 활용할 수 있는가, 또 한 가지는 웹에서 학습자들이 길을 잃어버린다는 많은 지적이 있었기에, 과학탐구능력을 향상시키기 위해 어떻게 교사가 안내된 탐구수업을 이끌 수 있는가 이다. 기존의 문헌을 토대로 하여 상호작용적이며, 안내된 웹 활용 수업의 모형은 다음과 같은 특징을 가지고 있다. 첫째, 수업모형은 기본적으로 준비→계획→실행→반성의 단계를 거치는데 이는 반복하여 피드백 되고, 수정될 수 있다. 둘째, 학습자 개인은 웹에서 다양한 자료로 학습을 하며, 그 후에는 반드시 모둠활동에서 동료 상호간의 피드백, 교사의 피드백이 이루어지게 하였다. 셋째, 정보의 바다라 일컫는 웹에서 학습자가 헤매거나 학습의 목표를 잃어버리는 것을 방지하기 위해 교사는 수시로 학습목표를 재상기 시키며, 과학적인 탐구를 할 수 있도록 안내하는 역할을 한다. 넷째, 홈페이지는 학습자가 학습의 길을 벗어나지 않도록 학습을 차례로 안내하는 역할을 한다. 그 날 배울 내용, 할 활동, 선행학습, 후속학습을 제시하고, 웹에서 자료를 찾기 힘들어하는 학습자를 위해 도움이 되는 사이트를 제공한다. 다섯째, 교사는 학습자가 활동을 하면서 탐구적인 사고를 할 수 있도록 질문기법을 제공하는 동시에 기록을 할 수 있는 탐구일지를 제공한다. 연구자가 설계한 수업의 효과를 살펴보기 위해 한국교원대학교 물리교육 연구실에서 개발한 과학탐구능력 검사지를 사용하였으며, SPSSWIN 9.0을 이용하여 t-test로 통계처리하였다. 연구자가 설계한 수업을 실험반에 처치한 결과 실험반은 과학탐구능력 사전 검사에서 16.450, 사후 검사에서 19.825로 유의미한 차이를 보였으며, 이러는 유의미한 향상은 과학탐구능력 수준이 상, 중, 하 모두에게서 보여 지고 있었다. 또 사전검사 결과 유의미한 차이가 보여 지고 있지 않았던 비교반과는 실험처치 후 매우 유의미한 차이의 향상을 보였으며, 과학탐구능력 요소별로 살펴보았을 때 10개 요소 중 7개의 요소에서 유의미한 향상을 보여 연구자가 설계한 웹을 활용한 수업이 과학탐구능력 향상에 긍정적인 영향을 주었다고 할 수 있다. 위와 같은 연구결과의 원인을 분석해 보면 다음과 같다. 첫째, 웹의 다양한 자료와 자신이 직접 웹 상에서 학습하게 하는 기회는 개별학습이 효과적으로 이루어 질 수 있게 하였다. 둘째, 웹의 상호작용적인 특성이 교사와 학습자간의 피드백을 원활하게 이루어 질 수 있게 하였다. 셋째, 웹과 학습자들의 친밀성과 자신의 개별학습으로 인해 학습자들의 학습에 주체적으로 적극적인 참여가 이루어 질 수 있었다. 넷째, 교사의 안내와 웹에서의 안내는 학습자들로 하여금 학습목표에 잘 도달할 수 있도록 하였다. Classes utilizing web enable learners to discover, judge and learn information autonomously through web and to interact with other students, teachers and experts for cooperative learning. Regardless of many advantages, existing web-based instruction or study was limited to the provision of learning content focusing on homepages so that they did not show the interactive aspect of the web effectively. When looking into the efficacy of utilization in science subject, they did not look into the enhancement level of science process skill but they were limited as the studies investigating science related aspects and the change of interest. Therefore in this study, an interactive web-based instruction was developed to enhance science process skill of the learners and what kind of effects the designed web-based instruction made on science process skill was reviewed. When designing a web-based instruction, following two things were emphasized. One was how much could the instruction use interaction of web and the other was how a teacher could perform guided classes to enhance learners' science process skill, as there were comments that learners were easily lost in Web. The interactive and guided web-based instruction developed based on existing literature had following features: First, the class model was basically composed of Preparation-> Planning-> Execution-> Review, during which repetitive feedbacks were allowed to enter in order to modify the models. Second, individual learners learned with various materials on Web and the they would have feedbacks from their fellow students or from teachers in the group activities. Third, to prevent learners from being lost in Web, a sea of information or losing their learning objectives, teachers reminded their learning objectives frequently and guided them to do scientific investigation. Fourth, homepage played the role of a guide not to digress from the learning of the day. It provided content to learn on the day, activities to do, previous studies, further studies and sites that would help learners who found difficulties in discovering learning materials on Web. Fifth, teachers provided questioning techniques to let them have science process skill thought during the learning activities and an 'Inquiry Diary' to record the learning activities. To investigate the efficacy of the classes developed in this study, 'Science Process Skill Questionnaire' developed in Physics Education Lab of Korea National University of Education was used and they were statistically treated by t-test using SPSSWIN 9.0. When the instruction designed by the researcher was given to the 'Experimental Group', they marked 16.450 in pre-test and 19.825 in post-test. This significant enhancement was shown in all the students regardless of levels. Comparing to 'Comparison Group', which did not show any significant difference from 'Experimental Group' before the treatment with the designed instruction, the 'Experimental Group' showed significant enhancement after the treatment. When looking into elements of science process skill, they showed significant enhancement in seven out of ten elements. The results implied that the web-based instruction that the researcher designed gave positive influence on the enhancement of science process skill. The analysis of the causes of results is as follows: First, diverse materials of web and the opportunities to study autonomously enable them to perform individual learning effectively. Second, the interactive characteristics of web allowed active feedbacks between teacher and students. Third, because learners were accustomed to web and the learning was done in individual learning pace, they could participate in the learning process actively. Fourth, the guide of a teacher and web-based guides helped them to arrive at the learning goals.

Author has studied on the 614 cases, amalgam restoration of out patients(in insurance patients) who recieved amalgam restoration at the private dental clinic in Taegu city from Jan, 1. 1985, to Dec, 31. 1985. 1. The most of amalgam filling was permanent teeth, the number of permanent teeth was 568(92.5%), and decidous teeth 46.(7.5%). 2. The filling in mandibular teeth was more numerous than maxillary teeth: mandibular teeth were 396(64.5%) and maxillary teeth were 218(35.5%) 3. The simple cavity filling was more numerous than complex cavity filling: the simple cavity filling were 406(66%), and complex cavity filling were 208(34%). 4. Upper teeth applied to the simple cavity filling were 112(18.24%), lower teeth applied to the simple cavity filling were 294(47.88%), upper teeth applied to the complex cavity filling were 106 (17.26%), lower teeth applied to the complex cavity filling were 102,(l6.61%). Thus both arches of complex cavity filling were similar. 5. The much numerous application to the amalgam filling was the first molar tooth: the number part of which was 237,(38.59%),: secondly, second molar tooth 206, (33.55%), thus the greater of amalgam filling was applied to molar portion of permanent teeth (91.34%).

Coccidioidomycosis is a fungal infection that results from inhaling the airborne arthroconidia of the Coccidioides species. It is an endemic disease in the southwest part of North America and rarely diagnosed in Korea. As tourism to endemic areas and the number of immunocompromised patients have been increasing, the incidence of this infection has increased in non-endemic areas. Treatment is usually successful with antifungal agents; however, recurrence is common. It is difficult to decide when to discontinue the antifungal treatment especially in non-endemic areas where doctors are not familiar with the disease. We report a case of recurrent coccidioidomycosis manifesting as osteomyelitis after the treatment of the patient for disseminated coccidioidal infection. The complement fixation test was a useful tool for the assessment of patient response and to evaluate suspected recurrence.

The history of measurement is as old as that of human beings. They began measuring lengths and weights when agriculture and stockfarming were commenced. Then quantities continuum were measured as well as quantities discontinuum. The beginning of measurement was begun by comparing things each other, and the ways of direct comparing and of indirect comparing were adopted. Thereafter unit systems were socialized, and they were determined on the base of the decimal system, as the societies were gradually progressing, and simultaneously the metric system was created. Studies in details concerning every field of the unit systems follow.

白南郁 건국대학교 1984 論文集 Vol.19 No.1

In order to understand the society of three Hans of old Korea, I've studied on the number of the small and large states of three Hans written on San-Kuo-Chi and Han-Ch'uan, Chinese history books on the basis of the result of an input of their statistical data into a computer. I've also studied on their territory at the rate of their population and arable land. 1. The small and large states of Ma Han are considered to be 50 to 59 states. The large states with about 10,000 houses each come to 1 to 4 states and the small states with thousands of houses each come to 49 to 55 stares The term of thousands of houses is somewhat vague but may he considered to be the meaning of 1,100 to 1,900 houses or so as the case may be. 2. Jin Han and Byun Han states are considered to be 20 to 29 slates. When I put them into separate states I found that large slates with 4,000 to 5,000 houses came to nine states and small states with 600 to 700 houses came to 11 to 23 states

Geometry is one of the subjects which were developed earlier than any other in the field on mathematics, and it has been the object of study of many scholars for thousands of years. Accordingly it has been developed into a wide range, and its logical basis was established lastely in a rigid criticism. As the relation between geometry and numbers is deep, the origin of numbers is described first. The knowledge and technique concerning geometry in ancient times can be supposed through Herodotus(B.C 5th century), the Greek historian's History, and the pyramids which are conjectured to have been built about 3,000 years ago, and geometry was put in order and completed later by the Greek's initiative. The relationship between numbers and geometry follows.
