Korean Dative and Locative Cases:

Young Sik Choi 현대문법학회 2015 현대문법연구 Vol.83 No.-

YoungSik, Choi. 2015. Korean Dative and Locative Cases: Postposition or Morphological Case Marker. Studies in Modern Grammar 83, 1-24. I propose that the dative and locative case particles are not postpositions but morphological case markers, quite in contrast to the common view in the literature (Yang 1972, Cho and Sells 1995, and Suh 2013 among many others). I will show the difference between the nominative and the accusative and the dative and the locative in case drop, case stacking, and case spreading is attributed to the fact that the dative case and the locative case are inherent case, as compared with the nominative and the accusative, which are structural case par excellence. The present proposal has a nontrivial implication regarding the other case particles typically argued as postpositions in Korean.

For more effective intraperitoneal chemotherapy, the authers made 5-fluorouracil-polyglycolic acid composite disks(FU-PGA disks) with 5-fluorouracil and polyglycolic acid, a biodegradable polymer. We inserted the FU-PGA disk into the peritoneal cavites of Sprague-Dawley male rats, the control and three experimental groups; one FU-PGA disk insert group(300mg/kg), two FU-PGA disk insert group(600mg/kg), and three FU-PGA disk insert group(900mg/kg). The control group received a similar number of PGA disk inserts. A pharmacokinetic study was performed to measure the 5-fluorouracil concentration in the peritoneal fluid, blood, and tissues(liver, kidney and heart) at 24 hours, 72hours and 168 hours after insertion of the FU-PGA disk. Light and electron microscopic studies were done. The results were as follows: 1) The number of white blood cells and platelets decreased after FU-PGA insertion. The degree was proportional to the duration and amounts inserted. The change in the number of red blood cells varied slightly. 2) Light microscopically, slight changes were noted at 168 hours in the 3 disk insert group (900mg/kg). Mild fatty change and hepatocyte degeneration around the central veins of the liver were noted, with vacuolar degeneration in the proximal convoluted tubules of the kidney. 3) Electron microscopically,the liver showed focal increases of lipid droplets in the hepatocytes, and irregular nuclear membrane with focal nucleolar segregation of the fibrillar and granular elements. Also the double membranous structure of the hepatocytes and Kupffer cells was widened with bleb formation. The kidney showed wide separation of the nuclear double membrane in the proximal convoluted tubular cells and mesangial cells, with vacuolation and myelin figure formation in the mitochondria of the proximal convoluted tubular cells, at 72 hours and 168 hours in the 2 to 3 FU-PGA insert groups. The heart showed focal loss of cristae,vacuolation and myelin figure formation in the mitochondria of the 2 to 3 FU-PGA insert groups. In conclusion, despite the large amont of FU-PGA inserted, the histopathological changes in the liver, kidney and heart were slight, and consonant with the very low amount of 5-fluorouracil concentrations detected in the liver, kidney and heart. The above results suggest that the FU-PGA composite can serve as a new device for releasing drugs in a controlled manner and easily targeted to intraperitoneal organs. This device can improve the efficacy of intraperitoneal chemotherapy for gastric cancer.

Sun-youp Park,Jin Choi1,Jung Hyun Jo,Ju Young Son,Yung-Sik Park,Hong-Suh Yim,Hong-Suh Yim,Hong-Kyu Moon,Young-Ho Bae,Jang-Hyun Park 한국우주과학회 2015 Journal of Astronomy and Space Sciences Vol.32 No.3

An algorithm to automatically extract coordinate and time information from optical observation data of geostationary orbit satellites (GEO satellites) or geosynchronous orbit satellites (GOS satellites) is developed. The optical wide-field patrol system is capable of automatic observation using a pre-arranged schedule. Therefore, if this type of automatic analysis algorithm is available, daily unmanned monitoring of GEO satellites can be possible. For data acquisition for development, the COMS1 satellite was observed with 1-s exposure time and 1-m interval. The images were grouped and processed in terms of “action”, and each action was composed of six or nine successive images. First, a reference image with the best quality in one action was selected. Next, the rest of the images in the action were geometrically transformed to fit in the horizontal coordinate system (expressed in azimuthal angle and elevation) of the reference image. Then, these images were median-combined to retain only the possible non-moving GEO candidates. By reverting the coordinate transformation of the positions of these GEO satellite candidates, the final coordinates could be calculated.

To evaluate the in-vivo effects of mitomycin-C-polyglycolic acid composite(MMC-PGA) the disk: shaped composite were implanted into the peritoneal cavity of the Sprague-Dawley rats. The pathologic changes were examined at various time points up to 12 weeks. Initially the soft tissue around the inserted disks showed capillary congestion at 3 days. Inflammatory infiltrates with foreign body giant cells appeared from the 2nd week and reached peak response at 6-8 weeks. These reaction diminished prominently at 12 weeks. No specific pathologic change was found in the liver, the kidneys, and the heart. The above results suggest that the MMC-PGA composite can serve as a new device for intraperitoneal chemotherapy of various types of cancers.

박영신,남영식,정상영,최재호,장기혁,박원호,Park, Young-Shin,Nam, Young-Sik,Jung, Sang-Young,Choi, Jae-Ho,Jang, Ki-Hyuk,Park, Won-Ho 한국섬유공학회 2012 한국섬유공학회지 Vol.49 No.1

In this work, effects of total draw ratio change on the mechanical properties of polyester fibers were studied. The process parameter was a total draw ratio and the draw ratios that were used ranged from 6.6 to 7.0. Tensile properties are determined from the tensile tester, and crystallite parameters from the density measurement and X-ray diffraction were discussed with the different total draw ratios. The tenacity, young's modulus and crystallinity were increased to 10.6 g/d, 123.2 g/d and 42.1%, respectively, with increase in the total draw ratio. The relations between total draw ratio and mechanical properties of high tenacity polyester fiber were discussed.

최충식,채정호,우동원,최영희,함웅,이규항,장미화 대한신경정신의학회 2001 신경정신의학 Vol.40 No.1

연구목적: 정신분열병 환자에서의 재활치료는 개인의 극복 기술과 능력을 향상시키고 재발을 유발시킬 수 있는 스트레스의 부정적인 영향을 중화시킴으로써 질병의 만성화를 막고 사회기능을 호전시킬 수 있기에 점차 그 중요성이 대두되고 있다. 본 연구는 만성 정신분열병 입원 환자에서 재활치료의 하나인 단축형 증상관리 훈련이 정신장애에 대한 자기 인식에 미치는 효능을 알아보기 위하여 시행되었다. 방법: 정신분열병으로 진단받고 입원 중인 환자들에게 재발경고징후를 규명하는 것, 재발경고징후를 관리하는 것, 지속증상을 극복하는 것, 술과 불법 약물을 피하는 것 등으로 구성된 승인-UCLA 사회기술 및 독립적인 생활기술훈련 단위 중 증상관리단위를 기초로 한국실정에 맞게 축약한 증산관리 훈련을 주 1회, 60분씩, 4∼5주간 실시하였고 실시 전후에 전신장애 비인식 평가 척도(Scale to Assess Unawareness ofMental Disorder; 이하 SUMD)로 자신의 정신장애에 대한 인식을 평가하였으며 임상적 전반적 인상(Clinical Global Impression;이하 CGI)로 임상 상태를 조사하였고 각 인구학적 변인들을 조사하였다. 결과: 환자 30명이 훈련을 완수하였으며 이들의 평균 연령은 36.6±7.6세였고 남자가 14명(46.7%), 여자가16명(53.3%)이었다. SUMD 점수는 훈련 전 16.9±4.0점에서 훈련 후 12.9±4.2점으로 유의하게 줄어 정신장애에 대한 자기 인식 정도가 향상되었으며(p<0.01), CGI도 훈련전의 3.7±0.9점에서 훈련 후 2.8±0.8점으로 유의하게 호전되었다(p<0.01). 환자의 연령, 발병시 연령, 유병 기간, 입원 기간, 항정신병약물 사용 용량, 교육 정도, CGI로 평가한 임상 상태등은 정신장애의 자기 인식 정도와는 관련성이 없었다. 결론: 정신분열병 입원 환자에서 단축형 증상관리 훈련은 정신장애에 대한 자기 인식을 증가시킬 수 있는 방법이 될 가능성을 확인하였으며 이 방법이 정신분열병 재활치료의 중요한 요소가 될 수 있음을 알 수 있었다. Objectives : The purpose of this study was to examine whether Symptom Management Module-Korean Brief Version(SMM-B) is effective as a psychosocial treatment of the inpat-ients with chronic schizophrenia. We also questioned which of demographic and clinical characteristics could be predictors of differential treatment response. Methods : The subjects were composed of 30 inpatients with chronic schizophrenia, who were trained with weekly session of SMM-B for 5 weeks. Before and after the training, the level of psychopathology, knowledge about schizophrenia were assessed as dependent variables by using Clinical Global Impression(CGI) and Scale to Assess Unawareness of Mental Disorder(SUMD). Results : Overall, patients showed improvement over the treatment period on psychopath-ology as well as knowledge about psychosis. Total scores of SUMD were changed from 16.9±4.0 before training to 12.9±4.2 after training(p<0.01) and scores of CGI were improved from 3.7±0.9 to 2.8±0.8<p<0.01). Howver age, gender, years of education, age of onset, duration of illness, duration of admission, numbers of psychiatric admission, and clinical status evaluated by CGI were not correlated with unawareness of psychosis. Conclusion : These results suggest that SMM-B could be a reliable method to improve self-aw-areness of psychosis in patients whth chronic schizophrenia and one of important elements in rehabilitation.

최석민,석종식,권정택,민병국,황성남,김영백,홍현종 대한신경외과학회 1996 Journal of Korean neurosurgical society Vol.25 No.10

To determine the factors affecting development and recovery of symptomatic vasospasm. the author analysed the results of patients with ruptured intracranial aneurysms treated by nimodipine and prophylactic “triple0H” therapy. From January 1991 to December 1995. 199 patients underwent surgery for ruptured intracerebral aneurysms. Combined hypervolemic hemodilution was initiated at the time of admission. Induced hypertension was added immediately after surgery(aneurysmal neck clipping). All patients received nimodipine intravenously or orally until the 14th day of SAH Sixty patients underwent surgery on Day 0 through 2 after attacks of subarachnoid hemorrhage(Goup A) 105 patients on Day 3 through 14(Group B). and 35 patients after Day 14(Group C). Of 199 patients. 76(38%) patients suffered from symtomatic vasospasm. Symptomatic vasospasm occured in 34% of Group A patients. 33% of Group B patients. and 5% of Group C patients. Symtomatic vasospasm occured more frequently in the older age group. the Fisher group 3 and Hunt & Hess grades 3, 4 and 5 groups. Of 76 patients who suffered from symptomatic vasospasm. 47(62%) patients recovered completely. The author analysed the relationship between recovery rate and sex, age. Hunt & Hess agrde and Fisher group among these 76 patients. Recovery rates between these groups were not significantly different. Based on this experience the author believes that Hunt-Hess grade. Fisher group and age are important factors affecting symptomatic vasospasm development.

항암제(Adriamycin, Cyclophosphamide, 5-Fluorouracil)로 유발된 흰쥐의 간독성에 대한 Squalene의 효과

최영복,김종세,윤중식 조선대학교 기초과학연구소 1998 自然科學硏究 Vol.21 No.1

The objective of the present study was to investigate the cytotoxicity of Adriamycin〔ADM〕. Cyclophosphamide〔CP〕, 5-Fluorouracil〔5-FU〕 in mouse liver cells (group A, B, c), and the protective effect of squalene to the hepatocytes to which ADM, CP, and 5-Fu-induced cytotoxicity(group A-1, B-1, C-1) was examined by transmission electron microscope. In the group A, The cisternae of rough endolplasmic reticulum(RER) and smooth endoplasmic reticulum(SER) are dilated/disoriented at 24 hours and 48 hours. The inner and outer membrane of mitochondria are detached or destructed, and attached ribosomes of RER are diminished in number. The cisternae of the SER are dilated, and the cristae of mitochondria are disrupted at 72 hours and 96 hours. In the group A-1, the cisternae of the RER and the SER are dilated at 24 hours. The cisternae of the SER are dilated at 48 hours. The cell organelles of hepatocytes are recovered from cytotoxicity at 72 hours. At 96 hours, hepatocytes were simillar to those of normal hepatocytes. In the group B, the cisternae of RER were partially destructed and attached ribosomes were remarkable decreased at 24 hours. A number of the mitochondria were dilated and increased in number, the filamentous materials also detected at 72 hours. In the group B-1, the difference between the normal and the treated groups were not detected at 24 hours, but the few mitochondria were expanded at the 72 hours. In the group C, the nucleus was destroyed at 24 hours and 48 hours group, however, somewhat repaired at 72 hours group. The dilated inner cavity and the irregular lamellae of the RER were observed continually until 72 hours group. The inner cavity of the SER were dilated in all groups. However, the destroyed and the normal membrane were observed simultaneously at 72 hours group. The inner membrane of the mitochondria were almost repaired at 96 hours group. In the group C-1, the nucleus was a little finfluenced by the toxicity of 5-Fu at 24 hours and 48 hours, RER were observed to keep the typical lamella structure of cisternae from 24 to 72 hours group, but inner cavity kept on dilating. In SER, inner cavity were also observed to flatten from 24 to 72 hours group. Mitochondria were always shown normal. All cell organelles were similar to those of normal at 96 hours. Accordingly, it can be said that the treatment of SQ prevents the cytotoxicity of ADM, CP, 5-FU on cell organelles of liver cell and that is concerned with the formation of membrane system of cell organelles.
