Acute torsion of the ovary and ovarian mass is a recognized surgical emergency, but rarely has the diagnosis been made preoperatively on the basis of imaging studies. The sonographic findings in 14 cases of surgically proven torsion of the ovary and ovarian mass are described. Mostly cystic ovarian mass, engorged vessel, dilated uterine tube, beak-like echo(torsion site), smooth mass wall thickening an free-fluid collection in cul-de-sac are described. More significant in terms of specificity were the demonstration in 6 cases(42.9%) of the smooth mass wall thickening and in 8 cases(57.1%) of a free fluid in the cul-de-sac. We report the sonographic findings of ovary and ovarian mass torsion that may suggest the preoperative diagnosis of this condition.

Serious problems of the environment protection and resource exhaustion are exhibited, due to the increase of the construction materials and activation of the remodeling, recently. Especially, most of the advanced countries, recycling plan for the waste concrete is vigorously progressing. The recycle of domestic waste concrete is, however, still in an early stage, and it has been only partially being used for the road fillers. As a counter-plan of activating recycled concrete, we have confirmed the hydration possibility of the waste concrete powder from the experiment on recycling the aggregate powder since 2000. Also, we have known that the strength is increasing when the heating time is longer, and baking temperature maintain in 700℃. The purpose of this study is to determine the most suitable production method controlling the duration of baking time for recycled cement from the compressive strength, X -ray diffraction and ingredient analysis test.

감성돔 (Acanthopagrus schlegeli)의 비장에서 주화세포인 BSBS를 확립하고 세포의 특성을 검사하였다. BSBS세포는 60회 이상의 계대배양이 가능하였고 형태학적으로는 상피성 세포였다. 세포는 20℃, 10%의 FBS가 든 L-15배지에서 배양하는 조건에서 잘 자랐다. BSBS세포는 해양버나바이러스 (MABY Y-6), 잉어의 봄바이러스병바이러스 (SVCV), 넙치의 랍도바이스(HIRRV)와 연어바이러스 (CSV)를 접종했을 때 세포변성효과가 나타났다. 새로 확립된 주화세포는 앞으로 많은 바이러스병의 연구에 유용하게 사용할 수 있을 것으로 생각된다. A stable cell line, BSBS (black seabream spleen), was established from the cells in spleen of black seabream, Acanthopagrus schlegeli, and characterized. Subculture maintained more than 60 passages and mophologically, BSBS cell was epithelioid cell. The cells grew optimally at 20℃ in Leibovitz's L-15 medium supplemented with 10% fetal bovine serum with incubation temperature of 20℃. BSBS cells supported the growth of marine birnavirus (MABV Y-6), chum salmon reovirus (CSV), spring viremia of carp virus (SVCV) and hirame rhabdovirus (HIRRV). Thus, the new cell line may be useful for studying wide range of fish viruses.

The relationships between the phenoxyherbicide 4-chloro-2-methylphenoxyacetic acid(MCPA) degradation by soil enrichment culture and several relevant physicochemical environmental parameters were examined. As concentrations of MCPA were increased, the degradation became inhibited. Biodegradation activity was higher at neutral pH or slightly acidic pH, but the activity was showed only partial degradation of MCPA at basic pH. The effect of inoculum size on the MCPA degradation was monitored. An increase in the inoculum reduced the lag period in the growth curve and accelerated the MCPA degradation. Increased concentrations of nitrogen and phosphorus as supplemental nutrients were inhibitory to the degradation of MCPA, respectively. Addition of yeast extract accelerated MCPA degradation, whereas the supplemented glucose inhibited the degradation of MCPA.

초등학교 학생이 바라본 영어교육 실태 분석 : From the students' perspective

오순임,우상도 한국영어어문교육학회 2001 영어어문교육 Vol.7 No.1

English has been taught as a compulsory subject at elementary schools since 1997 starting with third graders, to sixth graders. We have seen active research on teaching methods for elementary English, but little has been done from the learners' perspective. It is very proper time for English educators to review what the elementary students think about their English classes. The purpose of the present study is as following. First, we tried to find out how the students' attitude toward and interest in English have changed over the four-year English education. second we attempted to suggest the ways to promote the students' interests, and to increase understanding and participation in English classes. We also suggest that curriculum developers need to consider the students' lower interests and understanding in English classes as they move to higher grades, and that classroom teachers need to have a better understanding of what their students do and feel in the English classes.

The purpose of this study was to serve as a basis for the establishment and activation of a full-time physical education teacher system a t elementary schools, by grasping the actual condition of the full-time physical education teacher system's operation a t elementary schools of Cheju Do, and by understanding teacher's consciousness of the system and its institutional problems, as there was a need for a teacher to take complete charge of physical education that required, among nine elementary subject matters, more professional quality than any other subject matter did. For achieving the purpose, a questionnaire survey was carried out against class teachers, full-time physical education teachers, physical education head teachers, and managers. who served at 98 elementary schools with more than six classes, which were selected from among 106 elementary schools in city, eup and myon under the control of the Cheju Office of Education. The questionnaire used here was prepared by myself. The result of survey was analyzed by SPSS/PC' program, figuring out percentage of response frequency to each item. And x 'test was conducted to find out the relationship with variables concerned. The following findings were obtained, as a result of analyzing the collected data. First, the full-time physical education teacher system was gradually expanding. A teacher who hoped to be a full-time physical education teacher or who had a special physical education skill was chosen as a teacher who took complete charge of physical education. Skilled teachers avoided assuming complete charge of physical education because of additional special instruction and heavy school affairs assigned to them. However, it's found that the system was being properly established as managers and teachers got to have better understanding of that system. Second, teachers put very high value on the effect of teaching- learning by full-time physical education teacher, and very urgently felt the necessity of that system. But they avoided being a full-time physical education teacher on the ground of the lack of professional guidance ability. Thus, it seemed that the urgent task was to foster professional leader of physical education who can efficiently operate physical education instruction with specialized knowledge and excellent practical skill. Third, the shortage of teacher with expert ability needed to be a full-time physical education teacher counted as a relatively big problem in the operation of that system. The reason of avoiding taking complete charge of it was the lack of expert knowledge and practical guidance ability. In particular. formals teachers showed a marked tendency not to want to be a full-time physical education teacher. Many people showed an opinion that there would be little change in the quality of physical education, if the current method that a full-time physical education teacher served just for a year continued. Fourth, they thought the school year to which the system was applied first must change from the current fourth year the the third years. As a way to foster and supply full-time physical education teachers, they wanted the university of education to adopt a major system in one subject and a minor system in one subject of art or physical education, and they also hoped to receive re-education. What they wanted as institutional reward for a full-time physical education teacher was reduction of weekly lesson hours, improvement of treatment, and additional benefit for promotion or transfer.

To access the effects of some drugs such as piperazine phosphare, azathioprine and allopurinol in the experimental pneumoconiosis, 263 rats weighted 240-320 gm was divided into the control and eight experimental groups. To each group, the turbid solution mixed free silica, talc and natural coal dust of 50 mg in 0.8 ml saline were instilled intratracheally. At the begining and 5th week of experiment, piperazine phosphate(8mg/week orally), aspirin(1.5mg/day intramuscularly), azathioprine(25mg/day orally) and allopurinol(1.5mg/day orally) were administered simultaneously, while the dust turbid solution was only given to the control group. For each group the change of body weight. dry right lung weight, cellularity including total cell, macrophage, lymphocyte and neurtrophil in bronchoalveolar lavage fluid, superoxide ion, hydroxyproline, leukotriene B₄, tumor necrotsis factor, prostaglandin E₂were examined, and observed the pathological chages in lung tissue. The results were as follow : 1. The larger amount of their instilled dust and the longer observation period, the severer pathological findings were found in the lung tissue of each experimental group. 2. The body and dry right lung wight was not significantly changed in the experimental groups compared with the control group. 3. The number of total cell in bronchoalveolar lavage fluid was markedly less in the experimental group than the control one, while no significant difference was found in the percent alveolar macrophages and lymphocytes in both groups. However, the percent of neutrophiles was usually lower than in the control group. 4. The amount of superoxide ion was frequently less in the experimental group compared with the control one. 5. The amount of hydroxyproline was significantly lower in the experimental group than in the control one. 6. The amount of leukotriene B₄was usually less in the drug administered group than in the control one. 7. The amount of tumor necrotic factor was also frequently lower in each experimental group than in the control one. 8. The amount of prostaglandin E₂was usually higher in each experimental group than in the control one.
