Objectives : To establish an effective collaborate medicine treatment of acupuncture and western medicine for treating frozen shoulder patients. Methods : 59 voluntary patients were randomly assigned to Eastern treatment group(E group, n=22), Western treatment group(W group, n=17) and East-West treatment group(EW group, n=20). The E group received acupuncture treatment on LI15, TE14, GB21 and Master Dong's acupuncture points, Shin-gwan and Gyun-joong, twice a week for 4 weeks. The W group received suprascapular nerve block, subacromial injection and trigger point injection, twice a week for 4 weeks. The EW group received acupuncture and injection treatment including nerve block. All groups were instructed to practice self exercise during their daily lives. Evaluations were made before treatment and after treatment based on the change in shoulder Range of Motion(ROM) and the patient's satisfaction concerning the treatment was measured by Visual Analogue Scale(VAS). The obtained data were analyzed and compared. Results : The patient's satisfaction scores were E group 5.67, W group 7.73 and EW group 7.67. The E group and the EW group showed significant improvement in abbduction, adduction and flexion(p<0.05). The W group showed significant improvement in adduction(p<0.05). Abduction significantly improved(p<0.05) in the EW group compared to E group and W group. Flexion also showed improvement in the EW group, but the difference among the 3 groups was statistically insignificant. The three group's difference of change in extension and adduction was insignificant(p>0.05). Conclusion : Acupuncture and nerve block alone significantly improved ROM in frozen shoulder patients. Also collaborate treatment of acupuncture and nerve block significantly improved ROM in frozen shoulder patients. But the difference of the three treatments were significant only for improving abduction(p<0.05).

Lee, Young-Chun,Yang, Hyung-Sub,Kim, Dong-Ho 한국산업식품공학회 2002 산업 식품공학 Vol.6 No.3

Quality of frozen foods is significantly affected by the storage temperature and tie, and the consumers' demand for safe quality frozen foods is increasing. The objective of this research was to estimate the shelf life of frozen cooked meat dumplings, based on the changes in the selected physico-chemical and sensory quality attributes. Precooked frozen meat dumplings sampled from the same lot produced at a frozen food company in Seoul were stored at -10, -15, and -20℃. The meat dumplings sampled at 3- to 4-week intervals were subjected to the determination of volatile basic nitrogen (VBN), thiobarbituric acid (TBA), peroxide value (POV), surface color and shear value after thawing at 5℃ for 15 h. High quality life (HQL) was determined through the triangle test and practical quality life (PQL) through the scoring test. VBN, TBA and POV increased as the storage period was increased. HQL of the frozen meat dumplings were 189 and 252 days at -10 and -15℃, respectively. The estimated PQL were 349, 475, and 491 days at -10, -15, and -20 ℃, respectively. Statistical analysis indicated that there were significant relationships between sensory scores and VBN and POV of the stored meat dumplings. VBN was selected as the most reliable objective quality index for the shelf life determination (PQL) of the precooked frozen meat dumplings.

Portable low-cost Kinect sensor was used to analyze standing balance ability of the elderly. Eighty subjects who can walk alone and have a normal cognitive level participated in this experiment. Based on Berg Balance scale (BBS) test with 52 points, subjects were divided into Healthy older (HO: 46 persons, BBS: 53.80 ± 1.19) and Impaired older (IO: 34 persons, BBS: 49.06 ± 2.03) group. Each subject performed 30 seconds four different standing balance tests (EO: Eyes Open, EC: Eyes Close, EOf: Eyes Open on foam, ECf: Eyes Close on foam). Five variables (Mean distance, Range of distance, Root mean square, Mean velocity, 95% ellipse area) were calculated from the hip joint center movement of Kinect sensor. Results showed that there were significant differences between groups for four different standing tests. Calculated variables from kinect sensor showed significant correlation with BBS score. Especially, mediolateral mean distance, mediolateral root mean square, mediolateral range of distance and 95% ellipse area showed discriminative ability for all tests. Mean values of variables of IO were higher than those of HO, which means the decreased balance ability in IO compared with HO. Therefore, it was possible to estimate simple balance assessment of the elderly using portable low-cost Kinect sensor.

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.

This study was carried out to interpret hydraulic behavior and CO₂gas desorption in countercurrent packing tower which packed 50 mm plastic Hiflow-ring. The results are as follows: 1. To compare with conventional packing, 50mm Hiflow-ring could save energy because of low pressure drop under high load. 2. As relative error between calculated value and investigated value was less than 6% in the loading point and flooding point we found that we can predict results mathematically which occurres in the packing tower. 3. The unique magnituteds of packing which was used are as follows. C_(L) = 2.1×10^(-4), n = 0.787 so we can predict efficency which occurres.

The effects of Paeryungsan and Bojungchiseubtang on rats with nephrosis induced by a single intravenous injection of puromycin aminonucleoside(PAN), 2.5mg/100g of body weight were evaluated in the present study. The effects of Paeryungsan and Bojungchiseubtang on PAN nephrosis were evaluated by measuring ①the concentrations of albumin, total protein, total lipid, cholesterol, triglyceride, creatinine, blood urea nitrogen and uric acid in the serum, ②the amount of volume, protein, glucose and creatinine of the 24hours urine ③the concentration of blood in the urine, intake water, and by observing the changes of microscopic findings of kidney. The results are summerized as follows; 1. In the control group, the concentrations of cholesterol, creatinine, blood urea nitrogen in the serum, the amount of protein and glucose of 24 hours urine, creatinine of 24 hours urine and 24 hours urine volume on the 22th day were significantly increased. On the other hand, the concentration of albumin in the serum, the amount of creatinine of 24 hours urine on the 8th day, the volume of 24 hours urine and the intake water on the 8th, 15th day were decreased significantly. Electron microscopic findings were the segmental obliteration of the foot processes, swelling and villous transformations of the visceral epithelial cells and partial increase of the mesangial matrix. 2. In Paeryungsan group, the decrease of albumin in the serum and intake water were inhibited significantly. But the increase of the concentrations of cholesterol and blood urea nitrogen in the serum were inhibited significantly. And the amount of creatinine of 24 hours urine was increased significantly. There was no significant difference between Paeryungsan group and the control group in electron microscopic findings. 3. In Bojungchiseubtang group, the decrease of albumin in the serum and intake water were inhibited significantly. But the increase of the concentrations of cholesterol, total lipid, creatinine, blood urea nitrogen in the serum and the amount of protein in the 24 hours urine were inhibited significantly. The concentration of protein in the serum was increased significantly. There was no significant difference between Bojungchiseubtang group and the control group in electron microscopic findings. To conclude, PAN nephrosis was induced by a single intravenous injection of PAN 2.5mg/100g of body weight on rats. It can be inferred that Paeryungsan group has the effects of improving hypoalbuminemia in nephrotic syndrome and relieving azotemia when nephrotic syndrome is accompanied by the acute renal failure. It can be inferred that Bojungchiseubtang may improve proteinuria, hypoalbuminenia, hyperlipidemia in nephrotic syndrome. But there was no significant difference between Paeryungsan and the control group, between Bojungchiseubtang group and the control group in electron microscopic findings. So I hope that there will be further studies on the effect on the alterations of glomerular polyanion sites, and on the functioning mechanism of Paeryungsan and Bojungchiseubtang in the future.

알루미늄 캐스팅 타이어 몰드 주조시 트레드 부에 발생하는 열변형 예측에 관한 연구

In this study, the thermal deformation inside the aluminum casting tire mold was analyzed using the numerical analysis method and was investigated using the experimental method. The metal casting device used for manufacturing the tire mold products for automobiles in the actual industrial field was selected as an analysis model, and AI-Mg system alloy (AC7A) widely used for metal casting was selected as the mold material. For the numerical analysis, "COMSOL Multiphysics", the commercial code based on the finite element analysis (FEA), was used in order to predict the thermal deformation of the AC7 A including temperature, displacement and stress distribution. Also, in order to verify the results calculated by the numerical analysis, the experiment for temperature measurement inside the tire mold was performed using the K-type thermocouple under the same condition of numerical analysis method. In detail, the displacement inside the AC7 A tire mold was closely related to the temperature difference. The displacement for 15 minutes in the metal casting device appeared to be larger at the center parts of tire mold (tread part) than on its sides, and the one calculated for the time until it was completely cooled at atmosphere temperature after it was removed from the metal casting device appeared to be larger on the measurement points of 1, 4 and 7 near the atmosphere than on other points. Moreover, the stress inside the AC7A tire mold appeared to be larger at the center parts of tire mold (tread part) because of the shrinkage caused by the cooling speed difference for the initial 15 minutes, and larger on the measurement points 2, 5 and 8 when the mold was removed from the metal casting device because of slow cooling speed. From these numerical analysis conditions and results, when the temperature distribution calculated by the numerical analysis and the one actually measured by the experiment were compared with each other, it appeared that there was a slight temperature difference between them because of the latent heat of the AC7A during the phase change process but th6eir cooling patterns were almost similar results.
