이상규,박동원,장수일,Lee, Sang-Kyu,Park, Dong-Weon,Chang, Soo-Il 대한소아외과학회 1998 소아외과 Vol.4 No.1

신생아 및 영아에서의 횡격막 이완증은 일반적으로 드문 질환으로 인식되어 있지만 이에 대한 정확한 진단과 적절한 원인별 처치의 필요성은 널리 알려진 사실이다. 최근 저자 등은 5 례의 선천성 횡격막 이완증을 경험할 수 있었고, 전 례 모두 수술이 적응되었다. 전 례 모두 생후 2개월 미만의 영아였고 모두 남아였다. 이완 부위는 전 예에서 좌측 횡격막이었다. 증상은 3례에서 호흡기 증상이 있었고 소화기계 증상은 없었으며 나머지 1례에서는 체중 증가불능 이 외는 무증상이었다. 전 예에서 방사선학적 변화가 저명하였고, 횡격막의 절정은 제 3에서 제 5늑간에 달하였다. 수술 술기로 저자 등은 경복부 접근 방법에 의한 횡격막 습벽 봉합술을 선호하였으며 수술 결과는 임상적으로나 방사선학적으로 우수하였다. Although diaphragmatic eventration in newborn infants is generally regarded as a rare condition, the need for accurate diagnosis and appropriate intervention according to the etiological factors is well known. Recently the authors experienced five consecutive cases of diaphragmatic eventration below the age of two months(one to 55 days) requiring surgery. All were in males, and were left sided. Respiratory symptoms were present in 4 patients, and one patient showed inability to gain weight. Diaphragms were elevated to the level of the third to fifth intercostal spaces. Diaphragmatic plication through the abdomen gave excellent results. There was no postoperative mortality.

Mesenteric and omental cysts are rare lesions in childhood. These cysts are morphologically and pathologically similar to lymphangiomas that occur in other parts of the body. From 1980 to 1997, 8 children were diagnosed and treated for mesenteric or omental cysts. Their ages ranged from 18 days to 6 years. There were 5 boys and 3 girls. The main presenting symptom was abdominal pain. Operative procedures were complete cysts excision, complete excision with intestinal resection, or complete excision with intestinal resection and colostomy. Accurate preoperative diagnosis was possible with the current ultrasonographic imaging techniques. Complete excision of the lesion was possible in all patients and results were excellent.

핵 및 방사능전 상황에서 방사선에 의한 인명피해를 줄이기 위한 방안으로서 유개호에 자철석이 포함된 중량 콘크리트의 적용 가능성을 확인해보았다. 이에 본 연구에서는 자철광 콘크리트의 방사선 차폐효과를 분석하기 위하여 감마선원을 사용하여 차폐실험을 진행하였고 실험조건과 동일한 몬테칼로 모델링도 하였다. 그 결과 자철광의 함량이 증가할수록 감마선에 대한 차폐효과가 향상됨을 확인할 수 있었다. 향후 자철광 콘크리트가 군사적 목적의 시설물에 적용될 경우 방사선 차폐 측면에서 효과를 얻을 수 있을 것이라 기대한다. The purpose of this research is to analyze the gamma ray shielding effect of heavy concrete containing magnetic aggregate and to confirm the applicability to the military protective facilities. In general, a military concrete structure protects combatants from bullets, and also it provides some radiation shielding. In this research, experiments were conducted using a Cs-137 source to check the gamma ray shielding effect. In addition, the Monte Carlo N-Particle(MCNP) modeling was applied to evaluate the gamma ray shielding effect of a military structure. As a result, as the concrete thickness increased, the shielding performance improved according th the linear attenuation law. With that, as the ratio of magnetic aggregate was increased, gamma ray shielding performance was also improved. Therefore, this research verified that the application of magnetic aggregate concrete to military facilities for radiation shielding purposes would be useful.

Purpose: We evaluated the short and long-term changes of intraocular pressure (IOP) and studied its risk factors in pseudoexfoliation (PEX). Methods: A total of 40 eyes that had been newly diagnosed with PEX from January 1, 1995 to December 31, 2007 were included in this study. Age, gender and accompanying systemic disease were recorded. In addition, the age, gender, number of antiglaucoma eye drops, history of cataract operation, and history of systemic disease were evaluated as risk factors for IOP elevation during the follow-up periods. Pre and post cataract operation IOP was checked to evaluate the effect of the cataract operation on IOP. Results: The risk factors for IOP elevation in patients newly diagnosed with PEX were old age and female gender. After treatment, a long follow-up period and number of eyedrops were risk factors for IOP elevation. The cataract operation had a one year IOP control effect, especially in cases where the pre operative IOP was greater than 21 mmHg. Over the long term, however, the IOP control effect of cataract surgery could not be determined. Conclusions: IOP increased as result of increased patient age. Phacoemulsification was a protective factor for IOP elevation and may be a good method for short-term IOP control.

H8 조합(組合)에서 질소고정력(窒素固定力)이 가장 높았다. A laboratory experiment was conducted to find out the effect of inoculation with plant growth of associative $N_2$-fixing bacteria on the combination of eight different rice seedling with seven different associative $N_2$-fixing bacteria in which were isolated and identified from grasses and rice in saline and reclaimed saline paddy soil. Those were examined in N-free axenic culture medium. The result of this experiment exemplified the contribution of associative $N_2$-fixing bacteria to their host plant were varied much by the combination of rice cultivars and bacterial strains. Acetylene reduction ($N_2$-fixation) activity seems to be more variable with respect to the combination of rice cultivars and bacterial strains. The relationship between acetylene reduction activity and rice performance such as dry matter weight, plant height, root length, and number of root were statistically insignificant. However, in comparision with the control, the dry matter yield of Annapuruna was increased by inoculation of all the seven bacteria strains. Among the seven rice cultivars, the average acetylene reducing activity was the highest in Annapuruna, and Shingwang, and the lowest in IR-8 inoculated with Pseudomonas sp H8. Among the seven bacterial strains the highest acetylene reducing activity was obtained by the combination of Shingwang with Pseudomonas sp H8.

Associative heterotrophic nitrogen fixing bacteria were identified by immunodiffusion method in the histosphere of Planta-ginaceae, Caryophllaceae, Gramineae, and two types of rice cultivars. Twenty four strains associative heterotrophic bacteria with high ARA (more than 10nmole/tube/hr) were isolated from the histosphere of grasses and rice.* Those strains were related with 8 species of Azospirillum, 11 species of Pseudomonas, 2 species of Klebsiella and 2 species of Agrobacterium. Among them Azospirillum sp. and Pseudomonas sp. were predominant in histosphere of grasses and rice cultivars. From the histosphere of Oryza sativa, and Sagina maxima, the strains of Azospirillum, Pseudomonas, Klebsiella, and Agrobacter were identified while Pseudomonas was identified from Ischaemum anthephoroides, Plantago lanceolata, Miscanthus sacchuriflorum, and only Azospirillum was identified from Zoisia sinica, respectively. Associative nitrogen fixing heterotrophic bacteria were more abundant in the histosphere of Oryza sativa and Sagina maxima than that of other grasses grown in saline and reclaimed saline paddy soil. 우리나라 서남해(西南海) 간사지(干瀉地) 및 간척답토양(干拓沓土壤)에서 자생(自生)하는 벼과(科)(5종(種)), 석죽과(科)(2종(種)), 질경이과(科)(2종(種))식물(植物) 및 수도(水稻)(2품종(品種))의 뿌리에서 협생질소고정균(協生窒素固定菌)의 분리동정(分離同定) 결과(結果)는 다음과 같다. 1. 수답(水沓) 및 자생식물(自生植物)뿌리에서 24종(種)의 질소고정능(窒素固定能)이 높은 협생질소고정균(協生窒素固定菌)을 분리(分離)하였으며 분리(分離)된 세균(細菌)은 8종(種)의 Azospirillum 속(屬), 11종(種)의 Pseudomonas 속(屬), 2종(種)의 Agrobacterium 속(屬) 그리고 2종(種)의 Klebsiella 속(屬)의 세균(細菌)으로서 대체(大體)로 Azospirillum 속(屬)과 Pseudomonas 속(屬)의 세균(細菌)이 많았다. 2. 각종식물별(各種植物別) 협생질소고정균(協生窒素固定菌)의 종류(種類)는 수도(水稻)와 큰 개미자리 뿌리에서 Azospirillum 속(屬), Pseudomonas 속(屬), Agrobacterium 속(屬) 그리고 Klebsiella 속(屬)의 세균(細菌)이 갯쇠보리, 창질경이, 털질경이, 각시미꾸리광이, 및 물억새 뿌리에서 Pseudomonas 속(屬), 그리고 갯잔디에서 Azospirillum 속(屬)의 세균(細菌)이 각각(各各) 분리(分離)되었는데 그중 수도(水稻)와 큰개미자리가 타식물(他植物)뿌리보다 협생질소고정균(協生窒素固定菌)의 종류(種類)가 많았다. 3. 간척지토양수도(干拓地土壤水稻) 및 식물(植物)뿌리에서 분리(分離)된 세균(細菌)의 혈청면역학적동정결과(血淸免疫學的同定結果) 이들 협생질소고정균(協生窒素固定菌은 Azospirillum lipoferum, Pseudomonas sp, Agrobacterium radiobader, 및 Klebsiella planticola 였다.
