아연전해조에서 채취한 망간스라임에는 MnO₂가 59.94% 함유되어 있었다. 이 망간스라임을 물로 씻기, 환원배소, 용해추출, 용출액중의 불순물 제거 및 전해석출의 과정을 거쳐서 전해이산화망간을 합성하였다. 또한 X-선 회절분석에 의해 본 실험에서 합성된 MnO₂는 전지활성이 우수한 γ형임을 알았다. Manganese slimes which were formed in the zinc refinery elecarolytic cells contained 59.94% of MnO₂. The recovery process of MnO₂ from the slimes consisted of five steps, i.e., washing the slimes with water, roasting, dissolution of manganese, removal of impurities, and electrolytic synthesis of MnO₂. By X -ray diffraction method it was proved that the recovered MnO₂ had γ-typed crystalline structure.

갑상선 기능 항진증에서의 HbAlc와 Fructosamine 치와의 관계
이만호,김홍배,김향,이상종,정을순,한경학,이병원 대한내분비학회 1992 Endocrinology and metabolism Vol.7 No.1
Thyroid hormone may have various changes of metabolism process but the severity and pathogenesis of metabolism abnormalities in hyperthyroidism are incompletely defined despite vast studies. To evaluate the changes of carbohydrate metabolism in hyperthyroidism, we measured the serum levels of fasting blood sugar (FBS), total protein, albumin, hemoglobin Alc (HbAlc) and fructosamine in 42 normal controls and 60 patients with hyperthyroidism from March 1989 to August 1991. In hyperthyroidism group, those are as follows: FBS 91.9±11.7 ㎎/dl, total protein 7.0±1.1 g/dl, albumin 4.2±0.4 g/dl, HbAlc 5.3±1.0%, and fructosamine 2.1±0.3 ㏖/L. In normal control group, those are as follows: FBS 85.3±8.8 ㎎/dl, total protein 7.8±0.3 g/dl, albumin 4.4±0.2 ㎎/dl, HbAlc 4.9±0.2% and fructosamine 2.6±0.2 ㏖/L. The mean values of FBS and HbAlc in hyperthyroid group are higher than those of normal controls (p$lt;0.01) but those of serum albumin and fructosamine in hyperthyroid group are lower than those of normal contro with correlation each other. The higher level of FBS and HbAlc in hyperthyroid group compared to normal controls appeared as changes of carbohydrate metabolism. And it was revealed that fructosamine was not relable indicator of previous serum glucose concentration in hyperthyroidism. That may be originated from the concomitant decreased level of albumin as the greatest fraction of fructosamine. (J Kor Soc Endocrinol 7:46~51, 1992)

Human Echinococcosis (hydatid disease) is a parasitic disease by an infestation of the larval form of echinococcus species. This disease is commonly seen throughout the world, especially sheep and cattle raising areas, but rare in Korea. We experienced a case of unilocular hepatic echinococcal cyst. The patient was 49 years old male with epigastric discomfort and general weakness. He had had a history of working in the middle east for 7 years from 11 years ago prior to admission. In physical examination, the liver palpabled 2 cm in size and soft, smooth and nontender in character. Ultrasonogram, liver scan and abdominal CT of the liver revealed a large unilocular cyst in the right lobe. Percutaneous transhepatic aspiration confirmed the Echinococcus granulosus. Exploratory laparotomy and thoracotomy were done for him without any difficulties. Complete surgical removal of hepatic cyst was performed successfully. The cyst was measured by 10×9.5×8 cm in the size. The pathologic findings revealed the characteristic protoscolecies of echinococcus in the cyst.

CT Findings of Esophageal Schwannoma: A Case Report
이만호,류대식,엄대운,신동락,최수정,안재홍,박만수,유동곤 대한영상의학회 2015 대한영상의학회지 Vol.72 No.3
Esophageal schwannomas are a relative rare benign neoplasm that usually occurs in the upper esophagus, in the middle aged women. We report a case of a 67-year-old man with a lower esophageal schwannoma. This lesion was composed of homogenous density, iso-attenuating with the chest wall muscle on pre- and post-contrast chest computed tomography (CT). The CT findings of the esophageal schwannoma are similar to those of esophageal leiomyoma. Hense, esophageal schwannoma may be a differential diagnosis with esophageal leiomyoma.

정류소별 영향권 및 접근거리를 반영한 버스 통행배정 신뢰성 향상 방안 연구
이만호,이종훈,윤호선,손의영 서울연구원 2019 서울도시연구 Vol.20 No.3
In order to assess the adequacy of bus route adjustment and service, the demand for each bus stop should be estimated. Accessibility-related characteristics, such as access distance and access time, should be reflected in the regional conditions of the bus stop impact zone to ensure reliability of bus demand. The four-stage model is suitable for macro-analysis, such as traffic planning, since it is based on the O/D of the administrative town and the road network, but there is a limit to micro-analysis, such as demand and access time for each bus stop. In this study, the traffic card data were used to establish O/D for each stop and the bus network was established using BMS data. In addition, access distances reflecting user weights were calculated and reflected in the network properties according to the building's associative area within the zone of influence by station. This measure was applied to the case of Seoul Metropolitan Government's route adjustment to verify the high reliability by comparing and analyzing the error rate between actual and estimated demand. It is expected that this measure will contribute to determining bus route-related plans and evaluations based on quantitative indicators, such as estimating demand for ride-off and service levels for each bus line considering access time for each bus stop, and verifying feasibility of bus route adjustment plans. 버스 노선조정의 적정성 및 서비스 평가를 위해서는 버스 정류소별 수요가 추정되어야 한다. 버스 수요의 신뢰성확보를 위해 버스 정류소 영향권의 지역적 여건과 접근거리 및 접근시간 등 접근성 관련 특성이 반영되어야 한다. 4단계모형은 행정동 O/D와 도로 네트워크를 기반으로 통행배정하기 때문에 교통계획 등 거시적 분석에는 적합하지만 버스정류소별 수요와 접근시간 등 미시적 분석에는 한계가 있다. 본 연구에서는 교통카드 자료를 이용하여 정류소별 O/D를구축하고 BMS 자료를 활용하여 버스 네트워크를 구축하였다. 또한 정류소별 영향권 내 건축물 연상면적에 따라 이용자가중치를 반영한 접근거리를 산정하여 네트워크 속성에 반영하였다. 본 방안은 서울시 노선조정 사례에 적용하여 실제 수요와 추정된 수요의 오차율을 비교·분석하여 높은 신뢰성이 있음을 검증하였다. 본 방안은 정류소별 승‧하차 수요 추 정, 정류소별 접근시간을 고려한 버스 노선별 서비스 수준 평가, 버스 노선조정안의 타당성 검증 등 버스 노선 관련 계획및 평가를 정량적 지표에 근거하여 판단하는데 기여할 것으로 기대된다.

지구내부로부터 올라오는 유해파는 여러 가지가 있으나 특히 수맥과 자기맥(커리맥)이 중요하다. 인체에 피해를 없애려면 피하는게 상책이다. 그러나 주거형편상 곤란한 경우가 많으므로 차폐방법을 강구하게 되었고, 그간 각국에서 연구한 자료를 기초로하여 여러 가지 방식을 연구검토 하였다.

Lymphangiomas are infrequent tumors of the alimentary canal, About ten duodenal lymphangiomas have been reported. An 33-year-old housewife was admitted to this hospital because of epigastric pain associated with nausea and vormiting. She has been in excellent health until a week ago when she has been intermitent epigastric aching pain, nausea, and vormiting after meal. She has pregnant twice. Both family- and past histories are unremarkable. Endoscopic examination of the duodenum was shown two small cauliflower like polypoid lesions on the duodenal bulb. The lesion was sucessfu1ly removed by the surgeon. A case of lympghangiama of the duodenum is presented, the pathologic findings are described, and the literature is reviewed.
