A study was made on enzymes of carbohydrate metabolism in T. concretivorus grown with and without glucose. The present results show that T. concretivorus possesses high activities of pentose shunt pathway and related enzymes, glucokinase, G-6-P dehydrogenase, 6-PG dehydrogenase, and phosphoglucoisomerase, but low activities of enzymes unique to EMP(fructose-1,6-diphosphate aldolase). Although the synthesis of the latter enzymes remains largely unaffected by the growth enviroment, that of the former is stimulated by glucose. And the failure to detect ED pathway enzymes in cells grown in thiosulate or thiosulfate-glucose medium eliminates the ED pathway as a significant route of glucose catabolism in T.concretivorus. These results suggest that pentose shunt pathway performs an energetic role in glucose metabolism by T.concretivorus with EMP as a subway. The absence of ED pathway and the presence of pentose shunt pathway which is the major route of catabolism in T.concretivorus are similar to those of other obligately chemolitho-trophic thiobacilli. The G-6-P and 6-PG dehydrogenase are both NAD and NADP specific, but MAD predominant. However, the 3-PGAL dehydrogenase is only NAD specific. Since the specific activity of 3-PGAL generated from glucose is converted mainly into pyruvate which is channeled into the TCA cycle. All enzymes of the TCA cycle tested and NADH oxidase are detected in the cells of T.concretivorus grown in thiosulfate. The specific activities of fumarase and isocitrate dehydrogenase are high and others are low. The presence of two isocitrate dehydrogenase (NAD-and NADP-linked) may have important regulatory function for this organism. The activity of NAD-oxidase, which is implicated in the energy generating metabolism, was very high in the crude cell-free extract of T.concretivorus, recording 55.11 m.mu. mole/min/mg protein. This well coincides with the fact that activities of NAD-linked G-6-P dehydrogenase, 6-PG dehydrogenase and 3-PGAL dehydrogenase were high.

Purpose: An objective analysis and observations were to be done on hemiplegia patients that are wearing a walking support device, Stroke shoes. Their improvements in walking pace, the reduction of distance between the two knee joint, the increase of curve angle of the knee joint and their steps and the reduction of ankle joint upon swing phase were analyzed using a 20 walking analyzer. Methods: An examination was carried out to see the patients' communication skill and independent walking and then let them walk with the Stroke shoes on to get results before and after wearing it. Simi Reality Motion Systems GmbH (Germany, 2007) was used to analyze the results regarding knee joint and ankle joint angle changes of sagitta plane and coronal plane, stepping distances, distances between the knees and walking pace. Results: 1. The articulation angle of ankle joint during swing phase decreased and knee joint has shown a statistically significant increase in such value(p<0.05). 2. Only knee joint showed a significant increase in articulation angle during heel strike(p<0.05). 3. Knee joint showed a significant increase in articulation angle during toe off(p<0.05). 4. The distance between the two knees as well as their foot steps significantly decreased compared with when Stroke shoes were not worn(p<0.05). 5. Stroke shoes with FES have shown positive effects on the patients in improving their walking styles overall. (p<0.05). Conclusion: There was an improvement in rotation walking pattern by a reduction in the distance between the knees after wearing Stroke shoes with FES. Plantar flexion reduced that occurred in ankle joint during walking and flexion angle increased in knee joint, both of which improved foot drop which was a major problem in hemiplegia patients. Also it is believed that the device will have some positive influences on knee joint stiffening paralysis to aid in improving inefficient walking phases.

The code of the International Classification of Disease(ICD) is seriously questioned on its effectiveness in identifing an independent disease entity from similar conditions at general practitioner's offices. This study has attempted to show individual coding variations in ICD for similar ambulatory care conditions. It has been assumed that a following outpatient visit is regarded as the sane kind of visit owing to the same disease if a visit to the different source of care would be mad within an interval of less than two days. The 'D' health insurance association was selected for this analysis. The 'D' association had 153,298 members and made claims of 642,605 outpatient care in 1990. Out of the total outpatient claims, 8.6%(55,102 claims) were counted as the same disease which could meet the above assumption. Percent of conditions classified as the 10 leading causes of frequent visits which were matched accurately to the subsequent ICD diagnostic code found to be 15.8% on the average. The URI was noted for the highest concurrence rate of 20.4%. This proportion was even decreased to 11.6% on the case of chronic disease. Despite the fact that the assumption underlying the definition of the above same disease is rather rough and inappropriate, this study reveals that the code of ICD currently in use has weaknesses in seperating a certain independent disease from similar conditions at the outpatient setting. Thus, efforts need to be elaborated to meet the need of a new system of classification for conditions and diseases encountering at ambulatory care.

I사의 전기로 제강 슬래그(이하 슬래그)는 상당량의 금속철(metal Fe)과 wustite(FeO), magnetite(Fe$_3$O$_4$), gehlenite(${CaAl}_{2}{SiO}_{7}$) 및 monticellite(CaMgSiO$_4$)등으로 구성된다. 슬래그에 함유된 금속철(Fe 품위: 95%이상)을 회수하기 위해서는 금속철을 단ㄱ체로 분리시키는 것이 바람직하며, 매립으로 활용할 수밖에 없는 슬래그를 단계적으로 파쇄하면 대부분의 금속철은 구상의 단체로 분리된다. 구상의 단체인 금속철의 크기에 따라 흡인되는 자장의 세기를 측정하면 금속철이 흡인되는 최소 자장의 세기는 약 100G로 거의 일정하다. 다단계로 파쇄한 슬래그를 100G의 자장에서 회수한 산물은 95%이상의 철분이 함유된 금속철이었으나, 자장의 세기를 증가시키면 철의 산화물 및 알칼리 토금속류의 화합물등도 함께 회수되므로 품위가 저하된다. 따라서 매립되는 슬래그를 다단계로 파쇠하고, 각 입도에서 100G로 자선하면 파쇄된 슬래그에 함유된 대부분의 금속철을 회수할 수 있다. I사에서 매립하는 35만톤의 슬래그를 다단계로 파쇄하는 경우에, 30~4.7mm의 입도에서는 매립되는 전체 슬래그중의 약 0.73%인 2천 5백톤 정도의 금속철이 100G의 자장에서 회수될 수 있고, 4.7~0.3mm서도 약 1.2%인 4천 2백톤 정도가 회수될 수 있다. 그러므로 자력선별로 회수할 수 있는 금속철은 매립되는 슬래그중의 약 1.9%인 6천 7백톤 정도가 된다.

Background and method : The Cervi cornu parvum for children patients have been widely used nowadays: however, there have been no reports about the children patients' conditions and the parents' responses. To investigate these things, the questionnaires were used for the children patients(the ages between 0 and 15) who took the herbal medication combined with Cervix cornu parvum and their parents from January 1, 2000 to June 31 at the Dong-seo oriental Hospital. The chief complaints such as common cold, dyspepsia of using Cervi cornu parvum were divided into five categories and the changes were observed, scoring each stages. Besides, the quantity of taking herbal medication combined with Cervix cornu parvum, the expectancy, the satisfaction, the continual favor were included in the questionnaires. The result : 1. The trackable sample was 53: male infants 34(64.2%), female infants 19(35.8%). There is no differences between genders in the treating results. The treating results were increased after taking herbal medication combined with Cervi cornu parvum 2. When age is grouped by three categories(0-1, 2-6, 7-14 ages), the statistics shows that the treating results have no differences between each group(P>0.05) Regardless of the ages, the treats have correlated.(P<0.05) 3. When each symptoms made treated one case are analyzed, there have been correlations between the taking herbal medication combined with Cervi cornu parvum and recovery.(P<0.05) 4. The treating result have not affected by the expectancy.(P>0.05) Each group(good, moderate, poor) showed the recovery after the treatment.(P<0.05) 5. When the satisfaction divided into three groups(good, moderate, poor) there existed differences between groups.(P<0.05) Especially, the group with high expectancy increased the treatment. 6. About the recognition of herbal medication combined with Cervi cornu parvum is like this: the health refreshment, ordinary taking whenever turning-point of seasons comes, treatment, disbelieving the overdose of herbal medication combined with Cervi cornu parvum, disbelief about the security of the medicine such as fake medicine, mad cow diseases, the imported medicine, ignorance about the way of taking the medicine.

A three-year-old male jindo with generalized skin lesions (including seborrhea, hyperk- eratosis, alopecia, papules, and ecchymoses), pruritus lymph node enlargement, and fever was brought to Veterinary Teaching Hospital, College of Veterinary Medicine, Chungbuk National Uni- versity. There were no laboratory findings for parasites and fungi in the hair and skin But, the com- plete blood counts (CBC) showed leukocytosis and severe cosinophilia, It was suspected to be an inflammatory and allergic dermatitis. Thus, prednisoIone (0.5 mg/kg PO, BID for 1 week) and ampi- cillin (10 mg/kg PO, BID for 1 week given. One week later, pruritus and ecchymoses were reduced. These treatments were repeated for 7 day again. Three months later, the dog was presented again due to the relapse and exacerbation of the clinical signs. The signs were as follows; severe pru- ritus, vesicobullous skin lesions, anorexia, emaciation, lameness, and welling of carpal joints that showed inflammatory skin lesion and draining of synovia-like fluid. The values of WBC counts were returned to normal ranges. In contrast, eosinophilia was still observed. Coombs test for patient RBC and serum were negative. Hypoalbuminemia (2.5g/dl) was shown by serum chemistry. The uri- nalysis revealed and presence of leukocytes. Luxation finding of right radial carpal joint by polyarthritis was shown in radiography of affected joints.Lupus eryhematosus(LE) cells also appeared in peripheral blood and synovial fluid of affected joints. Definitely, antinuclear antibody (ANA) of patient serum using feline peripheral blood mononuclear cells was detected by all immu- nofluorescence. Based on these findings such as sedum ANA-Positive. major signs (skin disease, non- erosive polyarthritis with soft tissue swelling. and proteinuria), minor signs (fever), and LE cell-pos- itive, a diagnosis of systemic lupus crythematosus (SLE) was mad\ulcorner in this dog. The dog with SLE was administered with Pre(2.0 mg/kg PO, BID for first 4 week and then QOD) to inhibit the production of autoantibodies and with ampicillin (10 mg/kg PO, BID for first 4 weeks and then QOD) to prevent the secondary infection. The condition of this dog was monitored every 2 weeks by physical examinations, radiography, CBC, serum chemistry and urinalyais. At 8th week of treat- ment, the state of SLE evaluated by physical examinations and laboratory findings was markedly improved except for proteinura.
