연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

‘-(으)로’ 조사구에 대하여

이윤하(Lee Yoon-Ha) 국어국문학회 2005 국어국문학 Vol.- No.141

Whether or not the ‘-(eu)ro’ Kasus phrase as a sentence constituent is indispensable is fundamentally related with the argument structure of verb. That is to say, it means whether the ‘-(eu)ro’ Kasus phrase is syntactically required or not. But in spite of such cognition, it is really hard that we judge whether it is true or not. Therefore, I approach the problem through picking out the constituent which has semantically adjunct function. Then, the word order has to be considered.<br/> With the result, the ‘-(eu)ro’ Kasus phrases of the functions such as via, cause or reason, sense or value, instrumental, material, time or space background, norm, spacial background, and the ‘-(eu)ro’ Kasus phrases or the ‘-eseo’ Kasus phrases which express semantically equal meaning with NP of ‘NP+ha-’ construction or with Subject NP of verb ‘byunha-’ construction, and the idiomatic ‘-(eu)ro’ Kasus phrases or ‘-(eu)rosseo’ Kasus phrases, etc. are all estimated as the adjuncts.<br/> But the ‘-(eu)ro’ Kasus phrases of the functions such as goal, result or product, status property, and those related to time in the verb ‘(jeong)ha-’ construction, etc. are all estimated as the arguments.<br/> If such ‘-(eu)ro’ Kasus phrases are adjuncts, then they have a modifier scope individually such as adverb. It is deeply related with the unmarked positions of those. According to such description some adjuncts modify the lexical category, some adjuncts modify the sentence category, some adjuncts modify the mediate category which is larger than the lexical category but is smaller than the sentence category. However, idiomatic ‘-(eu)ro’ Kasus phrases or ‘-(eu)rosseo’ Kasus phrases are always the sentence category adjuncts, but ‘-(eu)roseo’ Kasus phrases in front of the sentence are not only those but also the ‘situation presentive word’ related to topic.

Matched Comparison of Fusion Rates between Hydroxyapatite Demineralized Bone Matrix and Autograft in Lumbar Interbody Fusion

Kim, Dae Hwan,Lee, Nam,Shin, Dong Ah,Yi, Seong,Kim, Keung Nyun,Ha, Yoon The Korean Neurosurgical Society 2016 Journal of Korean neurosurgical society Vol.59 No.4

Objective : To compare the fusion rate of a hydroxyapatite demineralized bone matrix (DBM) with post-laminectomy acquired autograft in lumbar interbody fusion surgery and to evaluate the correlation between fusion rate and clinical outcome. Methods : From January 2013 to April 2014, 98 patients underwent lumbar interbody fusion surgery with hydroxyapatite DBM (HA-DBM group) in our institute. Of those patients, 65 received complete CT scans for 12 months postoperatively in order to evaluate fusion status. For comparison with autograft, we selected another 65 patients who underwent lumbar interbody fusion surgery with post-laminectomy acquired autograft (Autograft group) during the same period. Both fusion material groups were matched in terms of age, sex, body mass index (BMI), and bone mineral density (BMD). To evaluate the clinical outcomes, we analyzed the results of visual analogue scale (VAS), Oswestry Disability Index (ODI), and Short Form Health Survey (SF-36). Results : We reviewed the CT scans of 149 fusion levels in 130 patients (HA-DBM group, 75 levels/65 patients; Autograft group, 74 levels/65 patients). Age, sex, BMI, and BMD were not significantly different between the groups (p=0.528, p=0.848, p=0.527, and p=0.610, respectively). The HA-DBM group showed 39 of 75 fused levels (52%), and the Autograft group showed 46 of 74 fused levels (62.2%). This difference was not statistically significant (p=0.21). In the HA-DBM group, older age and low BMD were significantly associated with non-fusion (61.24 vs. 66.68, p=0.027; -1.63 vs. -2.29, p=0.015, respectively). VAS and ODI showed significant improvement after surgery when fusion was successfully achieved in both groups (p=0.004, p=0.002, HA-DBM group; p=0.012, p=0.03, Autograft group). Conclusion : The fusion rates of the hydroxyapatite DBM and Autograft groups were not significantly different. In addition, clinical outcomes were similar between the groups. However, older age and low BMD are risk factors that might induce non-union after surgery with hydroxyapatite DBM.

This study was performed to investigate the effect of Angelicae gigantis Radix extract on the hepatic detoxifying enzyme activities and lipids. Male sprague-dawley rats were administrated the extracts with benzo(a)pyrene, a hepatotoxic agent, inducing liver damages. Results obtained from this study were as follows: 1. The markedly increased enzyme activities (AST, ALT, LDH, ALP, γ-GTP, GSH -Px) in B(a)P induced groups tended to be decreased by the treatment of the Angelicae gigantis Radix extract. 2. Liver GSH content and lipid peroxide activity were decreased by the administration of the extracts. 3. It tended that the curative effects were better than the protective effects of the extracts.

현대국어 대우법에 대하여(3) : '-시'-와 '-삽'-의 기능을 중심으로 mainly through the function of '-shi-' and '-sap'-

李潤夏 덕성여자대학교 인문과학연구소 1995 인문과학연구 Vol.1 No.-

This paper is planned in order to examine the various phases of the function of '-shi- and '-sap-' debated with the intricate theories and the views in the academic world, and therefore caused even the acute arguments more than the debate on the politeness in modern Korean and revealed in the all sorts of the treatisis and the books collected "An outline of the successive generations Korean grammar". Here, we will not debate any kind of calling what's right, right and what's wrong, wrong on the related theories and views. Because the basic purpose of this paper was posited to make a search for what to be right way for the discussion and comprehension on the problems related '-shi- and '-sap-'. Through the serious investigation, we called confirm that the theories and the views on '-shi- and '-sap-' in the academic world today were concealed many and few in those of the former learned man; '-shi- is the element related to the subject-person and the object-person referred, and '-sap-' is the element to be debated on the relation between the speaker and the hearer. But we also could discover the queer views getting out of the self-evident and firm ideas as this; the form combined '-shi- with '-sap-' has the function which reverse the subject-person and the hearer some more. While we could get the points which many ststements of a certain learned man would not maintain the logical consistency, which the origin of many theories on the function of '-shi- and '-sap-' would be begun with a certain view of a former learned man and therefore it would be possible to infer the one another's influence-relations related to the theories brought up.

금강 수서생태계의 구조와 기능에 관한 연구 : 수질 및 미생물

이규승,김윤석,오덕환,이영하,임항식 忠南大學校 環境問題硏究所 1995 環境硏究 Vol.13 No.-

소백산맥의 주봉인 덕유산에서 발원하여 군산지역에서 황해로 유입되는 금강의 본류는 총 유로연장이 401.4km에 이르는 우리나라 4대강 중의 하나이며, 대전광역시, 충청남북도 및 전라북도 일부지역의 생활용수 및 산업용수의 공급원으로서 대단히 중요한 역할을 담당하고 있다. 1960년대 이후 계속적으로 추진된 경제개발과 공업화 정책에 의해 인구의 도시집중화, 생활수준의 향상등이 이루어지고, 이에 따라 양질의 생활용수 및 산업용수에 대한 수요는 계속적으로 크게 증가하고 있는 실정이다. 그러나 금강의 경우 도시의 생활하수, 공업단지로부터의 공업폐수, 유역의 축산폐수 등에 의해 수질을 비롯한 수환경의 악화가 점차 심화되고 있으며, 이에 따른 수서생태계의 변화도 매우 큰 것으로 보고되고 있다. 특히 최근에 조성된 바 있는 금강 하구둑이 94년 8월부터 가동되고 있고, 또 1995년 이후 금강종합개발이 중류와 하류지역을 중심으로 대대적으로 시행될 예정이어서 금강 본류의 수환경은 장차 많은 변화가 예상된다. 수환경의 변화는 생육하는 생물들의 종조성은 물론 군집의 구조와 기능에 큰 영향을 미치기 때문에 금강 본류의 수서생태계에도 많은 변화가 수반될 것으로 예측되고 있다. 이와 같이 금강본류를 대상으로 하는 사업이 시행된 후 야기되는 수환경의 변화는 장기간에 걸친 조사를 요구하며, 이로부터 얻은 결과를 사업 시행 이전의 조사 결과와 비교함으로써만이 효과적으로 그 경향을 파악할 수 있다. 또한 이러한 비교 분석은 수질관리를 위한 대책 수립과 효율적인 사후 환경관리를 모색하는데 대단히 중요하다. 이에 반하여 지금까지 금강을 대상으로 한 수환경 및 수서생태계의 조사 연구는 단편적인 분야에 대하여 극히 단기간 수행된 것이 대부분이고 정량분석이 아닌 정성분석에만 치중되었기 때문에 금강의 수질 및 생태게보존을 위한 자료로서의 기능을 발휘하지 못하고 있다. 이러한 관점에서 본 환경문제연구소에서는 장기(향후 5년 이상)적인 계획하에 금강본류를 대상으로 수서생태계의 구조와 기능을 조사ㆍ분석하고, 이를 통하여 금강의 수질 및 생태계보존과 수환경관리를 위한 기초자료를 수립하고자 한다. 이와 같이 본 환경문제연구소가 장기적으로 추진하려 하는 금강 수서생태계학술조사는 금강 수서생태계의 현황은 물론 금강을 대상으로 하는 여러가지 형태의 사업에 의한 변화 양상을 정확하게 파악하고, 이에 대한 적절한 대처 방안을 강구하게 할 수 있는 기초자료를 제공하여 줄 것으로 기대된다. 지금까지 금강에 대한 종합적인 생태계 조사가 이루어지지 않고 있음을 고려할 때, 본 학술조사는 장차 금강 수서생태계에 대한 연구의 지침이 될 것으로 기대되며, 이는 본교가 금강 생태계의 보존과 관리를 통하여 지역사회에 기여하는 중추적 학술기관으로서의 위치를 확고히 마련하는 계기가 될 것이다. 본 보고서는 이러한 연구계획의 1차년도 연구결과로서 수질 및 미생물, 수생식물, 어류, 동식물 플랭크톤, 수서곤충을 중심으로 금강 중ㆍ하류 유역 수서생태계를 구성하고 있는 주요 생물군의 구조와 기능을 정량적으로 조사ㆍ분석하는데 그 목적을 두었다. Heterotrophic microbial populations and physicochemical parameters of water samples collected from six stations on the Keum River have been examined from November 1994 to July 1995. The ranges for BOD and COD were 1.5-11.3㎎/L and 2.1-13.7㎎/L, respectively. At the station closest to the estuary, the values of BOD and COD were higher than at other stations, but those of PO₄-P were lower. Metal ions including Cu, Mn, Pb, Cd, and Hg were not detected at all. The population densities of heterotrophic bacteria amounted to 13.7-22.0% of the total bacteria. The densities of coliforms, Salmonella-Shigella, and yeasts were in the range of 49-538 cfu/ml, 16-271 cfu/100ml, and 30-259 cfu/㎖, respectively.

이상훈,윤하나,심봉석,이시내 이화여자대학교 의과대학 2003 EMJ (Ewha medical journal) Vol.26 No.2

Purpose : Ureteral stent is commonly used after ureterscopic stone removal(URS). However, there is no definitive clinical criteria in inserting the ureteral stent after URS. Patients often complain of bladder irritative symptoms, hematuria. flank pain and additive endoscopic prodedure is neces-sary to remove the ureteral stent. Therefore, we studied the clinical epicacy of selective ureteral stenting only when it is required. Materials and Methods : Of the patients who was taken URS, the following patients were exclu-ded from stent insertion ; 1) Patients who have mild hydronephrosis or symptoms less than 1week. 2) Patients who were able to insert the ureteroscope through the ureteral orifice without difficulty. 3) Patients who hardly have ureteral mucosal damage seen through the ureteroscopic field after the removal of ureteral stone. 4) Patients who did not need the additional lithoclast during the remo-val of ureteral stone. Other than the above patients and those with stones above the mid-ureter, a 6Fr. ureteral stent was inserted and kept for 3weeks. There were 29 unstented patients and 38 stented patients. Results : The average age of the non-stenting and stenting group were 37.5years old and 39.7years old and the average stone size were 0.68cm and 0.80cm. The average operation time was 3 minutes in the non-stenting and 8minutes(including ureteral stent insertion time) in the stenting group. Hos-pital stay was 3days in both groups. Intermittent gross hematuria and irritative symptoms of the bladder was shown for 3weeks after operation in most of the patients(32cases, 84.2%) of the sten-ting group while those in the unstenting group, the symptoms were relieved after2days after operation. Although mild flank pain was shown in few patients(4cases, 13.8%) of the non-stenting group, severe pain requiring intravenous analgesics was not seen in both groups. There were no specific findings in the intravenous urography which was done at 6weeks after operation, and no hematuria and pyuria was found in both groups. Conclusion : The selective placement of ureteral stent following the ureteroscopic removal of stone did not bring specfic complications. We believe that ureteral stent insertion will minimize the inconvenience especially in patients who need to return to their everyday living immediately after operation. Thus ureteral stent insertion should be used in limited situations. 요관경하배석술 후 많은 경우에 있어서 요관부목을 유치하고 잇지만 선별적으로 판단하여 설치할 경우 특별한 문제점이 없었으며, 수술 수 바로 일상생활에 복귀하여야 하는 환자들의 불편함을 최소화할 수 잇을 것으로 생각되며, 요관부목 설치는 제한적인 상황하에서 시행되어야 할 것으로 사료된다.

2-Bromoacetylnaphthalene을 螢光誘導體化劑로 利用한 Alclofenac의 HPLC 分析에 관한 硏究

李允中,曺正吉,河仁植,金容熙 成均館大學校 科學技術硏究所 1990 論文集 Vol.41 No.1

A simple, rapid and high sensitive method for determination of alclofenac is described. 2-Bromoacetylnaphthalene was used as the pre-column fluorescent derivatizing reagent for high performance liquid chromatography. Alclofenac was derivatized quantitatively into fluorescent compound by reacting with 2-bromoacetylnaphthalene in the presence of 18-crown-6 ether in acetonitrile. The optimum conditions for the derivatization such as concentration of KOH, 18-crown-6 and 2-bromoacetylnaphthalene, reaction temperature and reaction time were investigated. The structure of alcolofenac derivative was confirmed from IR, NMR and mass spectra. The fluorescence properties of alclofenac derivative were examined. The derivative was separated on a reverse phase column (Lichrosorb RP-8) in isocratid elution mode using the secondary mixture of acetonitrile and water as the mobile phase. The effluent was monitored by fluorometer.(Ex. 303, Em. 418 nm). The calibration plots for the peak area versus concentration of alclofenac observed to be linear(r =0.999).

貧血症과 赤血球過多症에 있어서 血淸 Erythropoietin 活性度에 關한 硏究

尹起英,李夏白,朴鍾茂 한양대학교 의과대학 1985 한양의대 학술지 Vol.5 No.2

Erythropoietin (Ep) is a glycoprotein hormone of mostly renal origin that stimulates red cell production in response to tissue hypoxia. Serum Ep activities provide important clinical clues in making the differential diagnosis of some types of anemia and polycythemia. The study was performed in order to evaluate the diagnostic value of serum Ep activities in 29 normal subjects, 43 anemic patients and 15 secondary polycythemia patients and to find out the relationship between hemoglobin concentration and serum Ep activities in these patients using the Enzyme Immunoassay with Second International Preparation for Ep. The results obtained were as follows: 1. Ep activities in sera from 29 normal subjects among children ranged from 11 to 72 mU/ml, with a mean of 37.10±16.54 mU/ml. There was no significant difference between the serum Ep activities in male and female subjects (p>0.05). 2. Ep activities in sera from 22 patients with iron deficiency anemia ranged from 48 to 400 mU/ml, with a mean of 153.5 mU/ml which was about 4 times higher than normal value. Ep activities in sera from 18 anemic patients with acute infection ranged from 35 to 290 mU/ml, with a mean of 134.05 mU/ml which was about 3.5 times higher than normal value. Ep activities in sera from 3 patients with aplastic anemic ranged from 620 to 840 mU/ml, with a mean of 720 mU/ml which was about 20 times higher than normal value. 3. Ep activities in sera from 15 patients with secondary polycythemia ranged from 12 to 140 mU/ml. In 10 of 15 patients, the mean Ep activities was 87.50 ± 25.60 mU/ml, which was about 2 times higher than normal value. In 5 of 15 patients, Ep activities were within normal range as a mean of 35.80 ± 17.23 mU/ml. In summary, a significant negative correlation was found between the hemoglobin concentration and the logarithm of the serum Ep activities in 43 patients with anemia (r=0.73, Y=3.6766-0.1802x) and Ep activities in patients with aplastic anemia was higher than those in patients with iron deficiency anemia at comparable hemoglobin concentration. From the above results, it was concluded that serum Ep activities in anemic patients are not only inversely related to the hemoglobin concentration but also to the activity of the erythroid bone marrow. While no significant correlation was found between hemoglobin concentration, hematocrit percentages and Ep activities in 15 patients with secondary polycythemia (r=0.18, 0.39 respectively).
