Background: Ischemia-reperfusion injury (IRI) is a leading cause of acute kidney injury with high morbidity and mortality due to limited therapy. AKI emerges in various clinical settings and is complex with outcome linking oxidative stress, inflammation, and cell death. Therefore protection of AKI is still an unsolved problem. Indomethacin is generally known that it inhibits the production of prostaglandins through the inhibition both cyclooxygenase (COX) 1 and 2. Prostaglandins have a wide variety of effect such as regulation of vasodilation, inflammation, regeneration, pain, fever. Therefore effect of indomethacin in AKI is different according to injury model. We investigated whether indomethacin which inhibits the production of prostaglandins aggravate the renal injury in AKI mouse model. Methods: Male C57/BL6 mice (8-10 weeks old, weight 20~25 g) were used. Acute kidney injury is induced by bilateral kidneys pedicle clamping which were subjected to 20 min or 30 min at both kidneys. Mice were treated with indomethacin at before and after injury. Blood and kidney samples were collected at 24 hr after IRI. The expression level of creatinine, N-gal & Kim-1 were detected in serum. And the expression level of PGE2, cAMP and adenosine were detected in kidney. Kidney Injury score were measured by HE staining and TUNEL. Results: In bilateral AKI model, Serum NGAL level and creatinine level were significantly highest in indomethacin treated group compared to non-treated group (NGAL, p<0.05; creatinine, p<0.01). Indomethacin treated group showed significantly more necrosis and apoptosis compared to non-treated group. Furthermore, Indomethacine inhibited the production of prostaglandins, cAMP and adenosine. Conclusions: Indomethacin inhibits adenosine-mediated renal protection by inhibition of prostaglandin production in AKI. Therefore Indomethacin worsened renal injury by inhibition of prostaglandin production in AKI. * This research was supported by a grant of the Korea Health Technology R&D Project through the KHIDI, funded by the Ministry of Health & Welfare, Republic of Korea (grant number :H15C2212)

The purpose of the research is to investigate the effects of a portfolio system on students' socio-psychological classroom environments in elementary science class. Two schools were selected from a metropolitan area, a city, and one school from a rural area in central Korea. Two fifth-grade classes were sampled from each school selected, and one class is assigned to experimental group and the other to control group, respectively. The total number of participants of the study is 399. Portfolio system was administered to experimental group, and conventional teaching to control group for two and half month. WIHIC, an inventory to measure socio-psychological classroom environment, was administered as a pre-and post-test. Experimental group gained statistically higher scores on WIHIC after administering portfolio system. They showed more positive perceptions on sub-areas of WIHIC such as teacher support, task orientation, and equity. There is interaction between region and group: the effects of the portfolio system is highest in rural area, lowest in metropolitan area, and the city in between. Portfolio system have positive effects on students' socio-psychological classroom environments. Enhanced socio-psychological classroom environments is expected to contribute to positive self-concept, higher science achievements, and self-directed learning.

A low density microcellular foam was prepared using inverse emulsion polymerization method. First radically polymerizable styrene monomer and water with nonionic surfactants formed inverse emulsion, then this system was polymerized. The microcellular foam was obtained by removing water phase. The morphology of emulsion foams with system variables was examined in terms of pore size, cell structure, bulk density, and specific surface area. The emulsion system variables including monomer feeding methods, oil phase/water phase ratio, surfactant/water ratio, and mechanical stirring conditions were consider in this study. The ratio of surfactant/styrene rather than that of styrene/water shows dominant effect on the pore size of emulsion foams. While the open-cell/closed-cell morphology was mainly determined by the ratio of styrene/water. Mechanical stirring also has an effect on the pore size. Sorbitan monooleate among various nonionic surfactants seems to be the best surface active agent in styrene/water inverse emulsion system.

金善範 울산대학교 1984 연구논문집 Vol.15 No.1

都市史硏究의 目的은 歷史的 틀속의 都市가 現在와 未來의 都市에 示 하는 바를 透視해 보는 데 있다. 東洋의 都市成長은 西洋과는 달리 機能分化나 都市의 內的 成長이 未洽하였다. 本稿에서는 近代化(1400-1800年代)의 東洋3國(韓·中·日)의 代表的 都市(漢陽·北京·江戶)를 都市成長에 따른 都市空間패턴을 硏究하기 위하여 그 都市空間의 形成過程, 形態, 計劃原理등을 比較하여 共通性과 獨自性(傳統性)을 抽出하고자 하였다. 比較方法은 發達要因別 比較 및 物理的形態의 比較에 의한 結果의 比較를 통하여 이루어 졌다. 結果的으로 東洋3國은 相互影響面에서 古代로부터 同一한 思想的 脈絡을 이어왔으나 近世代이후 各己 獨自的 樣相을 띄게 되었다. 따라서 次後의 都市計劃은 西歐的 技法과 함께 獨自的이고 傳統的인 原理를 調和시키는 思想的 原理가 必要하며 使料의 檢討·蒐集·硏究를 통한 都市史硏究의 刮目할 進展이 期待된다. This paper tries to define the generalities and the particularities of the three major cities-Seoul of Korea, Peking of China and Tokyo of Japan-through the comparative study on their urban formation processes, morphologies and planning principles between the fifteenth and the nineteenth century. It may be concluded that the three cities share some cognate context in theirs ancient planning philosophies and they appear to have taken on different paths with the dawn of the Modern Age. The paper proposes that the modern planning techniques which are based on the scientific rationalism to be supplemented with the traditional values, especially in the case of the future urban planning of Korea.

The delivery of the proper care to the emergency dental patients is more important in the aspdect of community dental service. To attain such a purpose requires the sacred duty to the training of oral and maxillofacial surgeons. This is a retrospective study on the characteristics of dental injuries and diseases in emergency patients. Ths study was based on a series of 2,649 patients treated as dental emergency patients at K country hospital of medical college, from Jan. 1, 1993, to Dec. 31, 2000. The obtained results were as follows. The trauma(71.6%) was the most frequent cause in dental emergency patients, odontogenic infection and oral hemorrhage were next in order of frequency. The primary interdental wiring and transpalatal wiring were frequent proper methods with rubber drainage for prevention of hemorrhage and infection in the primary care of jaw fracture. The peak incidence(45.0%) about the infection group was occurred in the pulpitis of advanced dental caries, and common treatments were the medication of antibiotics & anagesics and I&D. In the dentoalveolar hemorrhage group, a major cause was postoperative hemorrhage(57.9%) and hemostasis was obtained by pressure dressing, suture and drainage of infected wound. About TMJ disorder group, the peak incidence was showed in the post-traumatic myofascial pain dysfunction syndrome and its primary care was medications(anagesics & sedatives). In the other groups, various irritable specific pains were complained, such as trigeminal neuralgia-form pain, acute stomatitis, chemical burn, terminal stage neuritis of head & nech cancer and their primary care methods were various individually. For the rapid and correct care of the emergency dental disease above, well-trained education should be presented in the intern and resident curriculum of oral & maxillofacial surgery.

본 연구에서는 우리 나라 초·중·고등학교 학생들의 과학 탐구 능력에 대한 종단적 추이를 분석하였다. 1997년에는 우종옥 등(1998)이 개발한 검사지를 사용하였으며, 1999년에는 이를 일부만 수정하여 사용하였다. 조사 대상은 성별, 지역별 등을 고려하여 표집하였다. 조사된 자료는 각각 횡단적으로 분석하고, 이를 바탕으로 학생들의 과학 탐구능력이 어떻게 변해 가는지 종단적 추이를 분석하였다. 조사 결과 초등학생들의 과학 탐구 능력은 유의미한차이가 없었으나, 중·고등학생들의 과학 탐구 능력은 유의미하게 향상된 것으로 나타났다. 학교 과학 교육의 질을 과학적으로 관리하기 위해서는 교육과정이 추구하는 교육 목표의 달성이 성공적으로 이루어지고 있는지를 국가수준에서 주기적으로 측정하여 부진의 원인을 진단하고, 개선 방안을 계속 연구하여야 할 것이다. The longitudinal trend of elementary and secondary students' science process skills were investigated to monitor the progress of science learning. Science process skill test, developedin an earlier study on developing a national science process skills assessment system, was revised and administered for the study on March, 1999. Subjects were sampled nation wide according to sex and region. The results of this assessments were compared to those administered on February, 1997. The results showed little difference on science process skills among elementary school students. However, secondary students showed marked increase in science process skills. More systematic and long-term research for assessing science process skills should be planned and performed periodically to provide empirical and foundational data for educational policy making.

본 연구는 perlite를 이용한 오이의 양액재배시 적정 배지량과 근권용적을 구명하고자 용기의 크기가 2, 4, 6, 8 및 10ℓ인 플라스틱 포트에 펄라이트를 채워 오이를 양액재배하였다. 근권용적이 증가할수록 초장, 경경, 엽수 및 엽면적이 증가하였고, 과실수와 과실중량에서는 근권용적이 큰 8ℓ와 10ℓ의 처리구에서 가장 양호하였으며 기형과 발생률도 낮은 경향이었다. 근권용적 6ℓ이상으로 하였을 때 경으로의 건물분배가 줄어들고 엽으로의 건물분배가 많았다. NAR과 CGR은 근권용적이 증가함에 따라 증가하는 경향을 보였다. 근권용적에 관계없이 본 실험 범위내에서는 LAI가 증가할수록 NAR과 CGR도 증가하는 경향을 나타내었다. This experiment was carried out to investigate the effect of container size and substrate volume on the growth and fruit yield of hydroponically grown cucumber(Cucumis sativus L.) plant. Seeds were sown in plug tray filled with coir dust on Feb. 13, 1998. Seedlings with 5 to 6 true leaves were transplanted in 2l, 4l, 6l, 8l and 10l plastic pots filled with perlite medium. Cucumber fruits were harvested with 1 to 2 day interval, and fresh weight, number and malform of fruit were recorded. Plant height, stem diameter, number of leaves and leaf area highly depended on the container size. Total fresh weight and the number of fruit were increased as the container size increased. NAR(net assimilation rate) and CGR(crop growth rate) increased with increasing the container size. Optimum container size for hydroponically grown cucumber plant using perlite medium was recommended as 8l per plant.
