Introduction: It has been well known that abdominal adiposity is related with insulin resistance and greater risk of metabolic disorder. Skeletal muscle plays central role in insulin mediated glucose disposal of whole body, but we only know a little about the association between skeletal muscle mass and MetS (MetS). The aim of this study is to clarify the clinical role of skeletal muscle mass in developing MetS through using skeletal muscle parameters by body impedance analysis (BIA). Methods: 1,042 healthy adults aged from 20 to 75 years who visited Yeungnam university health promotion center from Jun. 2008 to Jun. 2010 were enrolled. 204 subjects who had prior MetS or chronic disease that can affect to skeletal muscle mass were excluded. After 24 months from baseline, the metabolic parameters were assessed and the development of MetS was diagnosed using modified NCEP-ATP III criteria. From the BIA (Inbody 720), we obtained skeletal muscle mass (SMM, Kg), body fat mass (BFM, Kg), and visceral fat area (VFA, cm2). Then, we had defined as follows; percent of skeletal muscle mass (SMM%, %): SMM (kg)/weight (Kg), skeletal muscle index (SMI, Kg/m2): SMM (Kg)/height (m)2, skeletal muscle to body fat ratio (MFR): SMM (kg)/BFM (Kg) and skeletal muscle to visceral fat ratio (SVR, Kg/cm2): SMM (Kg)/VFA (cm2) Results: Mean follow up periods were 28.7±5.4 months. Among total 838 subjects (46.9±9.9 years, M:F=477:361), 88 (10.5%) were newly diagnosed MetS. 5th quintile of the SMM%, MFR and SVR was associated with decreased risk of development of MetS after adjusting for confounding factors. Conclusion: Decreased skeletal muscle mass may play critical role in development of the MetS and not absolute amount of skeletal muscle mass but relative ratio to body composition may be more important.

A ten months old, female Yorkshire terrier weighing 2.88 kg referred to veterinary teaching hospital of college of veterinary medicine, Konkuk University because of syncope, cough and dyspnea. First hematological and serum chemical test revealed thrombocytopenia, mild anemia, and increase of concentration of ALP (195 U/L). On 57 days later, second hematological and serum chemical test revealed polycythemia, increase of concentration of ALP (211 U/L), and Tchol (387 mg/dl). Right atrium enlargement, main pulmonary artery bulge and cardiomegaly (VHS = 11.5) were observed in radiographic findings. Ultrasonographic images showed both right and left ventricular dilation and turbulent flow between the descending aorta and the main pulmonary artery in color Doppler imaging. ECG showed left ventricular enlargement, SA block, and electrical alternant. Thoracotomy was performed through left fourth intercostal incision under isoflurane anesthesia. Patent ductus arteriosus was double ligated with 1-0 silk. Cough and dyspnea disappeared on 5 days after operation. Turbulent flow was not found in color doppler imaging of ultrasonography on 10 days after operation. Ten months later after the operation, syncope could not exist any more.

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.

The relationships of the isokinetic muscle functions and the flexibility of body trunk to low back pain(LBP) were investigated in 16 female ahtletes aged 21.5 years. Some of them were suffering from LBP syndrome without clinical signs of lumbosacral nerve root irritation or compression. The isokinetic muscle functions of subject's body trunk were evaluated using Cybex770. The peak torques of trunk extensors and flexors were measured at 60˚ /sec, respectively. The powers and the total works of trunk extensors and flexors were measured at 180˚ /sec, respectively. The back strength and the trunk flexibility of the subjects were measured with dynamometer and flexormeter. The frequency scale, the visual analogue scale(VAS), and the verbal rating scale(VRS) of subject's LBP were evaluated by interview. The Pearson' Rs between the variables and their significances were calculated for statistical analysis. The coclusions were as follows. 1.The frequency of LBP in female athletes was once in four months. 2.The VAS(0-10) of LBP in female athletes was 2.62. 3.The VRS(1-7) of LBP in female athletes was 2.81(weak). 4.The significant negative correlations were observed between the frequency of LBP and the muscle mass, the trunk flexibility, and back strength of subject. 5.The weak correlations exist between the VAS of LBP and the age of subject, between the VRS of LBP and the trunk flexibility of subject. 6.There were not any significant correlations between the variables of LBP and the isokinetic muscle functions, and other physical and physiological variables.

가압성형(Pressure Casting)에 의한 조성경사를 갖는 다층 Zr(Y,Ce)O₂TZP/뮬라이트 세라믹복합체의 제조를 위해 현탁액의 분산거동을 살펴보았다. 각 조성에 해당하는 현탁액의 분산안정성을 살펴보기 위하여 분산제(NaHMP) 함량을 각각 0~1 wt.% 첨가시켜 pH 변화와 제타 전위를 측정하였다. 그 결과, Zr(Y)O₂TZP, Zr(Ce)O₂TZP, 그리고 뮬라이트는 분산제의 함량을 각각 0.5wt.%, 0.8wt.%, 그리고 0.8wt.% 첨가하였을 때 최적의 분산 조건이 형성되었으며, 이때의 pH 값은 8(±0.2) 이었다. Zr(Y)O₂TZP/뮬라이트, Zr(Ce)O₂TZP/뮬라이트, 그리고 Zr(Y,Ce)O₂TZP/뮬라이트 현탁액에서 최적의 분산조건은 0.6wt.%(pH 8.2), 0.8wt.%(pH 8.2), 그리고 0.6wt.%(pH 8.2)이었다. The dispersion behavior of the suspensions for the pressure casting were investigated to fabricate mutilayer Zr(Y,Ce)O₂TZP/Mullite. A dispersing agent (NaHMP) was changed from 0 to 1 wt.%, and then pH and zeta potential was measured. As a result, the optimal contents of the dispersing agent for Zr(Y)O₂TZP, Zr(Ce)O₂TZP, and Mullite were 0.5wt.%, 0.8wt.%, and 0.8wt.% respectively, and the pH values were around 8(±0.2). The optimal contents of the dispersing agent for Zr(Y)O₂TZP/Mullite, Zr(Ce)O₂TZP/Mullite, and Zr(Y,Ce)O₂TZP/Mullite were 0.6wt.%(pH 8.2) 0.8wt.%(pH 8.2), and 0.6wt.%(pH 8.2), respectively.

Photo chemical splitting of water as a means of solar energy storage was studied. Hydrogen was evolved from water by visible light irradiation of the system containing a ruthenium complex or chlorophyll-a as sensitizer, several different types of electron carriers and catalyst such as colliodal Pt. Especially in the system including chlorophyll-a, manganese solution and benzylnicotin amide, hydrogen was produced. Hydrogen generation was more effective in the microscopically heterogeneous systems such as vesicle and microemulsion than in the homogeneous systems. In the microemulsion system containing chlorophyll-a and Mn^ⅡTPPCl, irradiation of that system by visible light resulted in the reduction of Mn^ⅡTPPCl to Mn^ⅡTPPCl and the oxidation of chlorophyll-a, but in the dark Mn^ⅡTPPCl was regenerated.

Electrical burns of the lips are most frequently seen in small children, who are apt to chew on electrical cord or plug, the ends of extension cords in their mouth, saliva creates a short circuit across the terminals within the plug, causing an electrical burn. Tissue destruction with electrical burns is sudden and extensive. Extensive, deep coagulation necrosis is instaneously produced by the extreme temparatures of electrical arc. If the child is well grounded, the circuit flow through his body may cause cardiac arrest. The purpose of this report is to document two cases of electrical lip burn and reconstruction of the lip defect with some local flap techniques. For case 1, Z plasty & V - Y plasty and lengthening of the commissure and in case 2, Abbe flap technique was used and scar was revised later. Z - plasty and V- Y plastry were used for scar release and Abbe flap was designed on lower lip to meet the need of upper lip. For short of right lip width, lengthening of the commissure was done. We are to report the improvement with forementioned operation on the patient of electrical burn upon the lip.

This study suggests the new ultraprecision finishing techniques for micro die and mold parts using magnetic field-assisted polishing. Conventional magnetic abrasives have several disadvantages, which are missing of abrasive particle and inequal mixture between magnetic particle and abrasive particle. Therefore, bonded magnetic abrasive particles are fabricated by several method. For example, plasma melting and direct bonding. Carbonyl iron powder is used as magnetic particle where silicon carbide and alumina are abrasive particles. Developed magnetic abrasives are analyzed using SEM. Feasibility of magnetic abrasive and polishing performance of this magnetic abrasive particles also have been investigated. After polishing surface roughness of workpiece is reduced from 85.4 nm Ra to 9 nm Ra.
