When applying prosthetic gait training to patients with lower limb amputation, monitoring the gait change process is crucial for establishing and modifying rehabilitation training plans. In addition, since human gait involves complex movement of several joints, it is necessary to analyze the organic movement of adjacent joints rather than a single joint in the lower extremities for understanding the process of gait change. Therefore, this study aimed to analyze changes in spatiotemporal parameters and lower limb coordination during prosthetic gait training in unilateral transfemoral amputees (TFAs). This retrospective case–control study included 10 unilateral TFAs and 10 healthy individuals as controls. TFAs received prosthetic gait training for 12 weeks and gait changes were analyzed every 2 weeks using a 3D motion analysis system. The measured variables were spatiotemporal parameters and the continuous relative phase between hip and knee joints. The highest improvement in walking speed was seen at week 4 of training, and the continuous relative phase was most symmetric at week 8. The lower limb coordination pattern was more in-phase in the TFAs than in the controls, and the coordination variability was also lower for the TFAs than for the controls. In addition, the rate of change in lower limb coordination of TFAs was lower than that of spatiotemporal parameters and was significantly different from that of the controls even after training. Considering that the decrease in lower limb coordination is related to gait efficiency, balance, and risk of fall, there is a need to develop therapeutic strategies that can further improve the coordination of TFAs.

This study is designed to assess Relationship between clinical diagnosis of Temporomandibular Joint Disorder and diagnostic finding of Cone Beam Computed Tomography(CBCT) The author performed clinical examination for TMD Patients who visited Orofacial pain clinic, Jin-ju ooo Dental office. CBCT(Cone beam computed tomography) was taken for 190 joints in 95 subjects. A Oral medicine and Oral radiologist evaluated CBCT each other. then we compared with that result, Condyle bony changes were classified by no bone change, flattening, erosion and osteophyte. The obtained results were as follow: 1. The Kappa index of the diagnosis between oral medicine and oral radiogist were high, the index of diagnosis by degenerative joint disease were more higher. 2. The Kappa index of panoramic view and CBCT was low, more condylar bone chages were observed by CBCT diagnosis 3. Condylar bone changes of the 54.2% of non-DJD group clinicaly was observed by CBCT diagnosis and no bone changes of the 15.3% of DJD group.was observed by CBCT 4. TMJ pain was associated with erosion of condyle bone change of TMJ. Crepitation and longest duration of TMD were associated with osteophytic bone change.

Extraction therapy is popular treatment protocol in orthodontics. Generally, symmetric premolar extraction is performed. But, in some cases, asymmetric extraction is required to solve asymmetric dental alignment. But asymmetric extraction treatment has side effects and disadvantages like a) collapse of dental arch form. b) canting of occlusal plane, c) extended treatment duration. For a good treatment result, we applied the orthodontic space closing arch wire with swivel joint to allow rotational movement of arch wire segments during space closure, Now we present a case treated with orthodontic space closing arch wire with swivel joint.

To construct expression vector for the human HPRT gene, pRSVneo plasmid conferring resistance to neomycin-kanamycin(Tn5) antibiotics and pHPT 31 containing human HPRT cDNA were used to subclone human HPRT cDNA. For construction of recombinant pRSVneo carrying human HPRT, pRSVneo-HPRT, the human HPRT cDNA fragment from pHPT31 plasmid was inserted into polyadenylation site (BamHI site) behind the neo gene fragment of pRSVneo plasmid. For the other expression vector, pRSV-HPRT, the neo gene and small portion of the untranslated 5′franking region were removed from the pRSVneo-HPRT. The HPRT gene of the two vectors were constructed in right orientation. Each recombinant vector was introduced into cultured HPRT-deficient mouse cell line, Sp2/0 by calcium mediated DNA transfection and the transfected cells were selected under HAT selection condition. The HPRT activity of the lysates from the selected cell was higher than that of the lysates from spleen cells of mouse. The HPRT activity of pRSVneo-HPRT vector was higher than that of pRSV-HPRT one. To find out whether the HPRT activity of the transfected cells selected under HAT medium was expressed by transfected vectors or by spontaneous mutations, it was cultured to reselect in G418 medium. It showed that the nature of the HPRT activity was resulted from the transfected vectors.

The author studied mainly the hallucinated phenomena of the 15 alcoholic psychotics who were hospitalized in Dept. of Neuro-Psychiatry, of Medical college, Chosun University, from October of 1972 to October of 1975. The following conclusions were obtained from the studies. 1) In general distribution of age, the average of the alcoholic psychotics was 40.5 years, with a range from 35 to 43 years. The range of age is significant, the alcoholic psychotics being a much more homogenous group. The rate of males to females among the alcoholic psychotics was 15 to 0. 2) This report will concern data from a group of 9 patients (60%) who were diagnosed as Delirium tremens and from 4 patients who were diagnosed as having Alcoholic Hallucinosis (25%) without schizophrenia and from 2 Patients (13%) of Korsakoff's psychosis who is less than others. 3) Alcoholic psychosis is the special disease of men in Korean society but not less and it is the most part in the lower class of the educational, socio-cultural level and the lower income class. 4) Their average of drinking capacity of a day is the 2 bottles (which is filled with 2 HOB) of SOJU (spirits) and 2-3 DOI of MAKOULLI, howerever they used not to get some eatables. 5) I found the light tremulousness (80%), insomnia (93%), night-mare or vivid dreams (53%), itching (47%), retching (33%), sweating (13%), seizure (27%) and blurred vision (20%) to be part of the alcoholic withdrawal syndrome. 6) The most frequent incidence was in the formed visual hallucinations (80%), followed by the formed auditory hallucinations (60%) and haptic hallucinations (58%). 7) In the contents of visual hallucinations, the bug, flea and snake are the most part but few seen the case of a rat. The contents of visual hallucinations in western people is the snake and rat which is the most part, such a difference between western and oriental people should be taken into account of the comparative cultural aspects. 8) Alcholic psychotics gave more responses regards as persecutory and every day affairs. 9) Alcoholic psychotics perceived the phenomena externally to any extent. 10) Alcoholic psychotics frequently thought that the hallucination was real at the time of it's appearance but later in the recovery period expressed recgnition of it's unreality and alcoholic psychotics behaved negatively or ambivalently in majority of cases.

동 모더나이트 촉매상에서 NOx의 제거 반응

모용기,이창용,최고열 서울産業大學校 2001 논문집 Vol.52 No.1

구리를 담지시킨 모더나이트를 이용하여 고정층 연속흐름 반응기에서 NO의 환원 및 분해 반응을 실시하였다 전처리로 산화된 CuO/HM의 NO 직접 분해 반응은 구리의 담지량 및 반응 온도의 증가에 따라 전화율이 증가하였다. CuO/HM 촉매상에서 CO를 이용한 NO의 환원 반응에서의 전화율은 공급되는 반응물의 양론비에 따라 달라졌다. NO/CO의 비가 1일때 NO는 거의 100% 가까운 전화율을 나타내었으며, 이 비가 증가할수록 전화율은 감소하였다. CuO/HM 촉매상에서 CO를 이용한 NO 환원 반응과 직접 분해 반응의 결과는 CuO/HM 촉매상에서의 결과와 유사한 경향을 나타내었다. The catalytic reduction and decomposition of NO has been carried out on copper impregnated mordenites in a packed bed flow reactor. The conversion of NO by direct decomposition on CuO/HM increased with the amount of copper loaded and the reaction temperature. In the reduction of NO with CO on CuO/HM, the conversion of NO was influenced by the ratio of NO to CO supplied as reactants The conversion of NO was almost 100% when the ratio of NO to CO was one. However, it decreased with the increase of the reactant mole ratio. The results of direct decomposition of NO as well as the reduction of NO with CO on Cu0/HM showed the same trends as those on CuO/HM
