본 연구는 학문 목적 한국어 학습자들이 한국어 읽기 수업의 과제 수행 상황에서 다중 텍스트를 활용하는 양상을 분석하였다. 다중 텍스트 활용은 학습자들이 텍스트를 이해하기 위해 관련성이 있는 여러 개의 다른 텍스트를 찾아 내용을 통합하는 활동을 의미한다. 학습자들마다 텍스트 이해 수준이 같지 않고 다중 텍스트를 활용하는 방식이 다르다는 점에서 그 구체적인 양상을 살펴보는 것은 한국어 읽기 교육 현장에 시사하는 바가 클 것이다. 이러한 목적으로 본 연구에서는 텍스트 활용 목적, 텍스트 사용 언어, 텍스트 출처, 그리고 텍스트 유형이라는 4가지 기준을 바탕으로 학습자들이 검색한 총 63개의 다중 텍스트 활용 양상을 분석하였다. 학습자들은 주제 이해를 위해 다중 텍스트를 활용하는 빈도가 가장 높았고, 학습자들의 모국어로 된 텍스트를 찾은 경우도 25%로 비교적 높게 나타났다. 또한, 사적 텍스트의 비율이 68%였으며, 텍스트 양식에 있어 단일양식 텍스트를 찾은 비율이 83%로 상당히 높게 나타났다. 이러한 분석 결과를 토대로 향후 한국어 읽기 교육 현장에서 다중 텍스트 활용의 효율성과 신뢰성을 높일 수 있는 교수 방안을 제안하였다. This study analyzed how Korean language learners for academic purposes use multiple texts when performing tasks in Korean reading classes. Multi-text utilization refers to an activity in which learners find several other related texts and integrate the content in order to understand the text. Considering that the level of text comprehension is not the same for each learner and the way they utilize multiple texts is different, examining the specific aspects will have significant implications for the field of Korean reading education. For this purpose, this study analyzed a total of 63 multiple texts searched by learners based on four criteria: purpose of text use, language used in text, text source, and text type. Learners most frequently used multiple texts to understand topics, and the number of times they found texts in their native language was relatively high at 25%. In addition, the proportion of private texts was 68%, and the proportion of single-style texts was found to be quite high at 83%. Based on these analysis results, the significance of the study can be found in that it proposes a teaching method that can increase the efficiency and reliability of the use of multiple texts in future Korean reading education fields.

N/A Objectives: High proportion of the elderly patients with renal disease were found to have primary glomerular disease and their clinical entities may be modified by treatment, supporting the renal biopsy as a diagnostic aid to institute appropriate therapy. Methods: We have retrospectively reviewed 49 patients of 60 years old or older in whom renal biopsies were performed from September 1985 to July, 1994. We've analyzed the histopathologic distribution, clinical presentations, clinicopathologic correlations, complications related to renal biopsy and treatment, and clinical response to the immunosuppressive therapy. Results: 1) Patients were 34 men and 15 women, 60 to 79 years of age (mean, 64.8±45) 2) The most common clinical presentation was nephrotic syndrome (65%). 3) The pathologic diagnoses of primary renal disease (36.73%) were MGN (13), MPGN (5), IgA nephropathy (5), MCNS (4), FSGS (4), Crescentic GN (2), nephrosclerosis (2) and PSGN (1). 4) The pathologic diagnoses of secondary renal disease (13.27%) were amyloidosis (4), TIN (4), HBsAg associated GN (2), cryoglobulinemia (1) and TMA (1). 5) In the cases of nephrotic syndrome with immunosuppressive therapy (20), 5 (25%) patients showed complete remission and 11 (50%) showed partial remission. 6) No one has recovered in the cases of chronic renal insufficiency and rapidly progressive renal failure. Conclusion: The most common clinical presentation and pathologic finding in the elderly were nephrotic syndrome and membranous GN respectively. The response to immunosuppressive therapy in nephrotic syndrome was good, but the possible complications related to the immunosuppression should be considered prior to the therapy. Renal biopsy is a safe procedure even in the elderly, and essential for the definitive diagnosis and for the appropriate therapy.

In general, low molecular weight water-soluble chitosan (LMWSC) has a weak antibacterial activity against pathogenic bacteria in physiological condition, because its cationicity acquired by amine group is less than high molecular weight chitosan (HMWC) and is reduced in salt condition. In addition, hydrophobic moiety is essential to increase antibacterial activity due to membranolytic action of chitosan. The aim of this study is to prepare the modified LMWSCs with a strong antibacterial activity in physiological condition. In order to hydrophobicity or cationicity, valine which is a hydrophobic amino acid or lysine which is a cationic amino acid, respectively, was conjugated to O-carboxymethyl group of LMWSC by increasing the grafting amount of amino acids. The structure were investigated by fourier transform infrared (FT-IR), 1proton nuclear magnetic resonance (1HNMR). Antibacterial activity of lysine-grafted LMWSC was more enhanced than valine-grafted LMWSC. The results proposed that amino acid-grafted chitosan has a potential as an effective antibiotic material.

N/A Objectives: Acute renal failure continues to be a significant cause of postoperative morbidity and mortality, especially after operations or trauma. Post- operative renal failure carries a mortality rate over 50%. We had two goals-to identify preoperative and intraoperative risk facors for postoperative acute ranal failure in patients groups undergoing various types of surgery, and by the use of multivariate analysis, to assess the relative important of these risk factors to provide a means of estimating the probability of survival in an individual patient. Methods: Data review was carried out for the 68 adult patients with ARF treated at 6 hospitals over a 3-year period(January 1991-December 1993). These patients were surgical patients who developed ARF in the postoperative period and subsequently underwent hemodialysis. Thirty-five factors to be of potential relevance to the outcome in postoperative acute renal failure were tabulated and analyzed. Results: 1) The ratio of male to female was 2:1, and the mean age was 51±17 years. The prevalence reached peak over 60 years. The mean death rate, numbers of hemodialysis, duration of oligura, numbers of organ failed, interval from ARF to recovery and interval from ARF to death were 63%, 9±0.8, 11±1 days, 1.7±0.2, 28±2 days, 19±3 days respectively. 2) The complications which developed during ARF included pulmonary complication(57%), hypotension (51%) and sepsis(32%), etc. 3) In findings related to operation, the mean duration of operation, interval from operation to ARF, numbers of transfusion during operation, frequency of hypatension during operation and duration of hypotension during operation were 211±126 min, 3.5±4 days, 23±3pints, 55%, 39.95±8.84 min respectively. 4) In the univariate analysis, hypotension, pulmonary complication, numbers of organ faild, pH (pH<7.2 or pH>7.55), APACHE II score, sepsis, duration of operation and duration of hypotension during operation were the only factors among 35 risk factors that significantly correlated with post- operative acute renal failure. In the multivariate analysis, the only significant risk factors for postoperative renal failure were hypotension and the presence of underlying disease. Conclusion: From the above results. The physician caring for the postoperative ARF patient may depend on these risk factors to predict morbidity and mortality. Whether or not these factors help to prevent the severe morbidity and mortality associated with postoperative renal failure remains to be studied prospectively.

In this study, thermosensitve hydrogels (ChGPs) were prepared using chitosan and glycerol phosphate disodium salt hydrate (GP) for adhesion inhibitor. The chitosan with various molecular weight (Mw) was studied for biomaterials such as adhesion inhibitor. The chitosan, fractionated by ultrafiltration techniques, showed narrow Mw distributions depending on the applied ultrafiltration membranes. The ChGP hydrogels according to Mw of chitosan showed sol-gel phase transition ranging from 31℃ to 37℃. Also ChGP hydrogels did not show any cytotoxic effect on the L929 cell. The results of scanning electron microscope (SEM) revealed that surface of ChGP hyrogels have a lot of porous. With these results, ChGP hydroges may be considered a potential candidate for various biomaterials such as adhesion inhibitor and drug and /or peptide delivery carriers.
