Renal papillary necrosis occurs most commonly in association with urinary tract infection, diabetes mellitus, sickle cell disease, vascular disease, and analgesic nephropathy. Clinical presentation may be related to symptoms of pyelonephritis such as flank pain, renal colic, hematuria, Proteinuria, recurrent fever. The necrotic tissue may be sloughed off, and the diagnosis can sometimes be made by finding piece of renal medullary tissue in the urine. Pyelography may demonstrate cavities and sinuses in the resion of papillae. Anuria & oliguria can lead to the acute renal failure, and especially prognosis and progress may be affect influenced by urinary infection. We report a case of renal papillary necrosis with ingestion of bear gallbladder. On pyelography, Persistent contrast is diagnostic clue of renal papillary necrosis. This case is not be related to urinary tract infection, but occurred acute renal failure. Expectant treatment was gone.

This study researches an obesity inde( and the reaiities of physical activity of etementary school childrnl and pvide basic data to instruct correct physical activity for low weight md obese childraL The subject was 813 Elementary School Chiliherl of grade 4-6 in Krimgiu and data were collected with a Physical Activir Questionnaire from fTs, USA The collected data ware an3ly2ed with real number, pnfentagf avErge and standard deviation techniques. The rarlge was by SPSS WIN. Both of them were in the normal range, between -38.3 and 77.7, between low weight and obesity The results are as follows : 1. An Obesity index according to grade and sex: the average obesity index of 423 boys was 7.56 ± 15.7, for girls it was 2.56± 14.3. Both of them were in the nrnmal range, between -38.3 and 77.7. There were low weight(-38.85±0.9) students as well as obese, including extremely low weight children (-38.85 ±0.9) and extremely obese children. 2. On the whole, in the Freouency of the 25 item physical activities breakdown, children reported to watch TV 1.(2.7±0.6), or do homework(2.1 ±0.9), more than three-fourths of the week, male children, however, played more football(2.0 ±0.9). As male obese children do less MET5, MET8(highly active activity) than male normal children, it was also discovered that low weight children do mnre severe activity in MET8(high activity). In female cases, it was revealed that neither do highly intense activity. 3. In physical activitiy, male children received higher points than fonale children with 92.94±37.95 to 74.46 ±29.50. On the whole, male and female obese children had lower score than normal children. 4. As for attitude toward physical activiv, male children(31.9614.37) had a positive attitude than female children (29.57 ±3.89), but obese male children had a negative attitude regarding activity viewed as normal. ThaefgrE in peventing obesity in elementary school childrerl the treating of under-weight childrern. should be included in the obesity Fgram so as to Pevent mal-nutrition or denciency. It is needed to instruct obese childrul to carry out interlsive w[rk-outs at least 3 times a weft through systematic grams. It is also needed that parents and teachers educate elementary school chil(hell from an early age with iDcimation on the frequency and interlsity of work-outs to prevent obesity. It is also desirable that children be eddcated to cauy out physical activities that address thetr specific needs. As a result of this study, obesif management must be started from elementary school and children should be instructed to act in hiRh-interlsity actirities when they spend leisure time.

This paper presents analysis and experimental results for effects of centrifugal force of the SMA-based tool clamping device. First, the corresponding theories of radial deformations resulting from the centrifugal force were described, and based on them, the radial deformations of the contact region between a tool and a tool holder were verified according to rotational speeds. Next, as for 3D-model of the tool holder, analysis of the radial deformations were carried out based on FEM. Finally, the feasibility of the SMA-based tool clamping device at high-rotational speed was experimentally verified by monitoring the clamped tool in mill-machining at 220,000rpm.

상악골 전방견인 장치 사용후 측모 변화 및 안정성에 대한 연구

박영철,신자영,유형석 대한치과교정학회 1997 대한치과교정학회지 Vol.27 No.1

골격성 제III급 부정교합은 성장과 연관되어 나타나는 부정교합의 형태로서 성장이 진행됨에 따라 그 심각성이 더해가는 데에 문제점이 있다. 성장기 골격성 제III급 부정교합의 원인은 크게 세가지로 분류할 수 있는데 하악의 과성장으로 인한 경우, 상악의 열성장으로 인한 경우, 그리고 이 두가지가 복합되어 나타나는 경우가 그것이다. 상악의 열성장을 동반한 골격성 제III급 부정교합 환자에서 성장의 조기에 상악골 전방견인 장치가 많이 사용되고 있는데 이 장치의 효과 및 측모변화에 대한 연구는 많이 시행되어 왔다. 그러나, 국내외 많은 선학들의 다양한 연구에도 불구하고 치료 후 측모 변화 및 치료 효과의 안정성에 대한 연구는 미미한 실정이다. 이에 본 저자는 상악골 열성장으로 인한 성장기 골격성 제III급 부정교합으로 진단받고 상악골 전방견인 장치로 치료받은 환자 중 재진단(follow-up)이 가능한 50명(남:18명, 여:32명)의 환자를 선별하여 성별, 치료개시 나이별, 구강내 장치 종류별로 분류한 뒤, 치료후 나타나는 측모 변화 및 치료의 안정성에 대하여 알아보고, 한국인 정상교합아동 20명(남:10명, 여:10명)과 상악골 전방견인 장치로 치료받은 환자사이에서 성장량에 어떠한 차이가 존재하는지 비교하여 다음과 같은 결론을 얻었다. 1. 상악골 전방견인 장치 사용전과 사용후를 비교한 결과 악안면 골조직과 연조직 및 치아의 계측항목에서 많은 변화량을 관찰할 수 있었다. 2. 상악골 전방견인 장치와 상악골 급속 확장장치(R.P.E.)를 함께 사용한 군에서는 악안면 골조직의 변화량이 크게 나타났으며 순설측 유지장치(La-Li)를 함께 사용 한 군에서는 치아의 변화량이 크게 나타났다. 3. 상악골 전방견인 장치 착용기간동안 치료군에서 나타나는 변화량과 정상군의 성장량을 비교하여 보면 상악골 전방성장량이 치료군에서 더 크게 나타났다. 4. 상악골 전방견인 장치 제거후 치료군에서 나타나는 성장 변화량과 정상군의 성장량을 비교하여 보면 상악골 전방성장량에 있어서 치료군의 성장량이 정상군의 성장량보다 적게 나타났다. 이상의 결과를 종합하여 상악골 전방견인장치를 사용하는 중에는 상악골의 전방성장을 촉진시키는 효과가 있으나 전방견인이 끝난 후에는 상악골 성장의 자극효과가 소멸되어 상악골 열성장의 양상으로 되돌아가는 경향을 관찰하였다. Skeletal Class III malocclusions are growth-related discrepancies, and the problems are more severe until growth is complete. Causes of skeletal Class III malocclusion are classified into mandibular overgrowth, maxillary deficiency, and combination of the two. Face mask has been recommended for treatment of Class III malocclusion with maxillary deficiency in the early time of growth. Numerous experiments were performed and clinical studies have been reported on face mask; nevertheless, studies on profile changes and stability after treatment of face mask are considered to be somewhat insufficient. The author selected 50 patients who can be checked for follow-up. They had been diagnosed as skeletal Class III malocclusion with maxillary deficiency and then treated with face mask; the sample group was divided according to sex, treatment beginning age, palatal suture opening(intraoral appliance). For each group, changing pattern of facial profile and stability of treatment observed, and comparison with 20 Korean normal children(Angle`s Class I). The following results were obtained. 1. Skeletal, dental, and soft tissue measurements indicated more changes in the amounts of maxillary forward movement during face mask treatment. 2. R.P.E. group showed more significant maxillofacial changes and La-Li group showed more dental changes. 3. Growth changes of maxilla induced in the treatment group during wearing face mask were much more than those of normal group. 4. Growth changes of maxilla in the treatment group after treatment of face mask were less than those of normal group. From the obtained data, it can be concluded that there was a stimulative effect on forward growth of maxilla during the use of face mask; however, on removal of face mask, the stimulative effect was eliminated and undergrowth tendency of maxilla resumed.
