폴리에스테르 섬유 감량시스템의 제어를 위해서는 처리조 내에서 감량되는 섬유가 목표 감량치에 도달했는지를 판단해 주는 장치가 필요하다. 본 연구에서는 가성소다용액의 초농도 및 섬유 감량 정도의 정확한 측정과 감량 종료시간의 산출 및 이에 따른 종료신호를 발생할 수 있는 폴리에스테르 섬유 감량기 전용의 자동적정장치를 개발하였다. To control caustic soda treatment system for the polyester fabric reduction, we need the device to determine that the fabric has been arrived target reduction value. In this study, we develope an automatic process titrator for the caustic soda treatment system. Major functions of the target titrating system are accurate measurements of the caustic soda concentration and then producing the end point signal for caustic soda treatment system.

To investigate the prognostic factors for the survival of transplanted kidney in patients with end-stage renal failure, 59 cases of renal transplantation from September 1986 to Feburary 1997 in Chungnam National University Hospital were analyzed retrospectively. The results were as follows: 1)The mean age of recipients was 33.8 years and that of doners was 38.9 years. The male to female ratio of recipients was 2.5:1, and that of donors was 1.03:1 2) Living related donore(LRD) were 79.6% and living non-related donors were 20.3%. The HLA-identical donors(ID) in LRD were 18.7% and HLA-haploidentical donors(HID) were 61.0%. In living non-related donors(LNRD), mean matched HLA-AB antigens were 1.56 and mean matched HLA-DR antigens were 0.56. 3) The average 5-year patient survival fate was 94%, and average 5-year graft survival rate was 70%. The 5-year graft survival fate of HLA-ID was 100%, and those HLA-HID and LNR were 70% and 36% respectively. 4) Total 33 episodes of acute rejection were found in 45.8% of transplanted patients. The number of acute rejection episode did not show significant difference between LRD and LNRD(P > 0.05). There was no significant difference in MLC between two groups(p > 0.05). 5) In comparison between the 18 patients who lost their graft function in 5 years and 17 patients who are maintaining graft function for more than 5 years, MLC was significantly lower in patients with functioning graft than of patients with non-functioning graft (p < 0.05). The number of rejection episode was also lower in patients with functioning graft than that of the patients with non-functioning graft(p < 0.05). However, there were no significant difference in recepient and donor age and history of pre-transplantation donor specific transfusion between two groups. With the results above, we can speculate that adequate donor selection according to good matched HLA typing and low MLC is very important for graft survival in renal transplantation. Prevention and treatment of acute rejection in renal transplantation is also na important factor for graft survival.

Background and objectives: Many conditions are responsible for the pathophysiology and progressive mechanisms of congestive heart failure. More recently, it has also become evidence that another class of biologycally activated molecules generically reffered to as cytokine these are also over expressed in congestive heart failure. Therefore, the purpose of this study was to measure concentrations of tumor necrosis factor-α(TNF-α), interleukin-6(IL-6) in mild to severe symptoms of heart failure and compare their values with those found in normal control and analysed correlation relationship between cytokine level, clinical findings and hemodynamic indicies. Subjects and Methodology: Levels of TNF-α and IL-6 were measured on pulmonary artery during cardiac catheterization in heart failure patients(n=32) and normal subjects(n=8) as well as physical examination and echocardiogram. Cytokines assay were performed on plasma using commercially available ELISA(Enazyme-Linked Immunosorbent Assay) kits. Results: Although the levels of TNF-α and IL-6 tend to increase in congestive heart failure group, the cytokines level was not made significantly statistical difference between congestive heart failure group and controls. When analyzing the correlation between the levels of PCWP(pulmonary capillary wedge pressure) and cytokines(TNF-α, IL-6), respectively, there were statistically significant correlation coefficient 0.32,(p<0.05), 0.39(p<0.01). The cytokine IL-6 and pressure of pulmonary artery were significant correlation.(correlation coefficient 0.36, p<0.02) More significantly, there was correlated with TNF-α and IL-6.(correlation coefficient 0.57, p<0.001) Conclusions: There was tended toward high concentration of TNF-α & IL-6 in congestive heart failure and significant difference for PCWP between TNF-α & IL-6, thus may be correlated with development and progression in congestive heart failure.

Objectives : This study was designed for the evaluation of relationships between PC-Bang (the place where people surf the internet, play computer games and etc) visit and stress in adolescents. Methods : 66 adolescents in city of Kangnung were interviewed in June, 2000. The independent variables were general characteristics of adolescents, the characteristics related to school activities and the length of time using PC-Bang. The amount of stress was measured by the Korean version BEPSI (Brief Encounter Psychosocial Instrument) scale. Results : The multiple regression analysis shows that the BEPSI score of female was higher than that of male by 0.18 (p<0.05) and the adolescents with more communication with their friends scored lower 4.04 (p<0.001) than others in the BEPSI. As the time used in PC bang increased, the BEPSI score was also increased 0.18 point per hour (p<0.01). Conclusion : This result shows that the time of PC-Bang usage is significantly related with the BEPSI score of adolescents.

"만주 Gurun"의 성립

김구진 弘益大學校 人文科學硏究所 2002 人文科學 Vol.10 No.-

依Shirokogoroff的調査, 滿洲族社會由 「Mukun」與「Hala」組成. 看淸文鑑與淸文總彙等文獻, 女眞族(滿洲族前身)社會一樣以Mukun與Hala構成. 察看滿洲族的氏族分化過程, 氏族逐漸發展成爲部族, 以氏族稱謂 「Mukun」, 以部族(姓)稱謂 「Hala」,「Mukun」與「Hala」成爲"滿洲Gurun"的基楚組織. 在於滿洲族社會, 一箇Gurun(國)的成立, 一定經過幾個階段. 從事農耕生活的兀良哈與斡朶里族, 以Falga(6·7寸以內近親)爲社會的最少基礎單位. 聚集幾個Falga形成一箇Gasan(村落), 又幾個Gasan成爲一箇Golo(邑鄕). 從事狩獵或,遊牧生活的兀狄哈族, 以Urilen(近親)爲生活的最少基礎單位. 聚集幾個Urilen形成一箇Tatan(帳棚), 又幾個Tatan成爲一箇Golo. 因爲一箇Golo之居民是同一血族, 所以居於一箇Golo之民使用同一Hala, 幾個Golo的大酋長聯合成爲一箇Gurun. 察看女眞族的大·小酋長之名稱, Falga的酋長(-da)稱謂Falgada, 以Gasan的酋長(-da)稱之謂化Gasanda, 以Golo的大酋長稱謂"頭頭(Dada)酋長". 聚集幾個"頭頭(Dada)酋長"聯合成一箇Gurun, Gurun的支配者自稱爲"Beile(王)", Golo的大酋長自稱爲"Amban(大臣)". 因此發展到Gurun的階段, "王與大臣"成爲上層支配階級, Gasanda與Falgada的中·下階級統率一般老百姓(Irgen). 從十六世紀末到十七世紀初, 女眞族社會遇到了大變革時期. 建州左衛的Nurhaci(努兒哈赤)開始統一諸種女眞之時, 滿洲各地已經成爲幾個Gurun與Beile(王). 他征討各地Gurun與Beile, 終於建立"滿洲Gurun"之後., 自稱爲Han.. Nurhaci Han指稱爲統率於滿洲各地的 "Beile(王)"之皇帝. 滿洲語之Han與蒙古語之Khan其語意是一樣. Nurhaci Han征討各地Gurun的 "Beile(王)"之時, 願意協助者或戰鬪之前投降的"Beile(王)"卽保存他們的地位, 其Gurun的種族亦編爲 "滿洲 Gurun"的一般老百姓(Irgen), 但是拒絶投降而被捕的人(Olji)淪爲奴隷. Olji(捕虜)構成滿洲族社會的最下層階級. 滿洲Gurun"的形成過程中, Nurhaci Han把Gurun的Beile(王)與Golo的頭頭(Dada)酋長作爲上層支配階級, Gasanda與Falgada編爲下層支配階級, 把Irgen作爲一般平民階級, 把Olji編成賤民階級. 這就是滿洲族上·下支配體系與社會組織. 一六一六年Nurhaci Han建國「後金」, 「後金」的語意就是繼承女眞族建立的「金」國. Nurhaci Han因爲通過"族的結合" 編成"滿洲Gurun"與"滿洲八旗", 所以一六三六年滿洲族(女眞族)可以建設大淸帝國, 可能 一六四四年不僅入關中原. 而且完成統一中國. 朝鮮與明朝如果女眞族統一之前, 用部族之間的離間之計或羈 政策, 可能沮止Nurhaci成立 "滿洲 Gurun".

김진형,최연익,정상구,박찬광,김충기,성만영 亞洲大學校 1987 論文集 Vol.10 No.-

In this paper, the design of the array type power MOSFETs is discussed in terms of on-resistance, breakdown voltage, placement of FLRs(field limiting ring) and threshold voltage. Also, 9-cell(square-on square grid) VDMOSs are fabricated to confirm the feasibility of the design method. Existence of optimum p-well spacing for minimum on-resistance, which is anticipated by the theoretical results is confirmed by the experiment of the fabricated power MOSFETs. Breakdown voltage of power MOSFET is upgraded by using two FLR's and their optimum placement is determined from the experimental results of the diodes with FLRs. The threshold voltage is controlled by the ion implantation within the design specification. Experimental results are in good agreement with the design specification. Experimental results are in good agreement with the design values. Characteristics of the fabricated power MOSFETs are 190Ω in on-resistance, 270V in breakdown voltage and 2.9V in thershold voltage.
