Purpose : Acute septic arthritis and acute osteomyelitis are not rare diseases in pediatric population. But when the diagnosis is delayed or inappropriate treatments are given, permanent disabilities of joint or bone can be followed. We analysed clinical manifestations, laboratory findings, X-ray findings, causative microorganisms and antibiotic susceptibility results of the two diseases in children. Methods : During January 1992 and May 2002, we conducted a retrospective study of 103 children who were diagnosed as acute septic arthritis and acute osteomyelitis. We selected out 34 children who had positive culture results in the blood or involved sites. Results : 19 cases were diagnosed as acute septic arthritis and 15 cases were acute osteomyelitis. These diseases were most common in preschool children and next in neonates. Hip joints and tibia were the most common sites in each disease. X-ray findings showed abnormalities in 6 cases(36%) of acute septic arthritis and 7 cases(50%) of acute osteomyelitis on admission. The most common microorganism isolated from the involved sites was Staphylococcus aureus; 12 out of 14 cases in acute septic arthritis and 6 out of 13 cases in acute osteomyelitis. Conclusion : It is difficult to make a clear initial diagnosis of the two diseases. We could not find any differences between these two diseases on clinical manifestations such as fever, swelling, tenderness and limitation of movements in joint and bone. The most common microorganism was Staphylococcus aureus.

최근 들어 국가질병관리체계 현대화가 세계 각국 정부의 중요한 과제가 되고 있다. 캐나다 연방정부는 감염병과 만성질환을 관리하고 생물테러 등 응급상황에 효과적으로 대처하기 위하여 새로운 질병관리조직인 Public Health Agency를 창설하기로 결정하였다. 연방정부는 앞으로 2년간 1,412억원을 투입하여 Agency를 설립하고 사업기반을 확충해 나갈 예정이다(Health Canada, 2004). 또 EU 집행위원회도 지난 3월 European Center for Disease Prevention and Control 설립계획을 최종 승인하고 ECDC가 발족하는 내년 한 해에만 71억원을 투입할 예정이다(Bosch, 2004). 이렇듯 새로운 질병관리조직들이 만들어지고 있는 직접적인 계기는, 중증급성호흡기증후군(이하 SARS) 사태로 대변되는 신종 및 재출현 전염병의 폭발적 발생(outbreak)이다. 전염병의 만연 사태가 일어나면서 각국 정부는 국민건강 보호의 중요성을 재확인하는 한편, 질병으로 인한 경제적 손실을 현실적 문제로 인식하게 되었다. 비전염성질환과 손상으로 인한 질병부담도 세계 각국의 골칫거리다. 서구 여러 나라에서는 비전염성질환과 손상의 질병부담이 이미 매우 큰 상태이며, 저개발 국가들은 전염병과 비전염성질환으로 인한 "이중의 질병부담(double burden of disease)"을 안고 있다고 한다. (중략)고 한다. (중략)

One step thermal potassium ion exchange process was carried out to form optical channel waveguides in an ErNb co-doped phosphate glass. Flowing oxygen gas into KN03 melt during ion exchange was effective to prevent glass surface damage that causes an increase of waveguide propagation loss. Amplification characteristics of the waveguides were evaluated at $1.5{\mu}m$ signal wavelength with 980 om laser diode pump. A 45 mm long waveguide whose processing parameters had been optimized exhibited a small signal net gain of 7.5 dB at the launched pump power of 160 mW.160 mW.

Purpose: We wanted to evaluate the clinical and radiological outcomes and the prognosis of various surgical treatments for the distal clavicle fracture with an acromioclavicular joint injury. Materials and Methods: A retrospective study of 21 patients with a minimum of 12 months follow up was done. We classified acromioclavicular (AC) injury into type I (only intra-articular fracture (IAF), 5 cases), type II (IAF with widening of the AC joint > 7 mm, 9 cases) and type III (IAF with AC joint superior subluxation > 50%, 7 cases). The distal clavicle fractures were fixed using plate (9 cases), mini screws (1 case), K wire and tension band wiring (10 cases) and transarticular pinning (1 case). Acromioclavicular or coracoacromial ligament reconstruction was not done in all the cases. Results: In 20 of 21 cases, bone union was achieved at an average of 8.4 weeks. Traumatic arthritis (5 cases), AC joint widening (4 cases) and AC joint subluxation (2 cases) were noted at the last follow up. The average UCLA score was 32.6 in the type I AC joint injuries, 34 in type II and 34.1 in type III. There was no relationship between the clinical outcomes and the preoperative AC joint injury pattern, postoperative traumatic arthritis, AC joint widening or AC joint subluxation (p>0.05). Conclusion: Satisfactory results were achieved by acute reduction and firm fixation of the distal clavicle fracture with AC joint injury. There was no relationship between the pattern of AC joint injury, the residual radiologic findings and the functional outcome.

후두 및 기관지 협착증은 대개가 기도확보를 목적으로 후두 및 기관내에 삽관을 시행하였을 때 삽관튜브에 부착된 cuff내에 압력이 높게 되면 점막에 혈류장애가 초래되고 궤양등의 점막손상이 뒤따르며 여기에 2차감염이 초래되어 육아종과 반흔이 생기면서 결국은 협착이 초래되는 것으로 알려져 있다. 이와 같이 손상된 후두및 기관의 점막에 산도가 강하고 소화효소가 함유된 위액이 역류되어 접촉될 경우 협착이 더욱 조장되리라고 가정할 수 있다. 따라서 위액이 과연 후두 및 기관지 협착증에 관여 한 것인지를 실험적으로 규명해 보고자 하였다. 실험동물은 가토를 대상으로 하여 Urethan마취를 시행하고, 삽관한 다음 합성위액 pH 1.5, 3, 5 짜리 용액을 기관 내에 1시간정도 관류시킨 다음 후두 및 기관을 적출하여 점막상태의 변화를 현미경으로 관찰하였다. 그 결과 산도가 강하고 펩신이 첨가된 합성위액으로 관류한 군에서는 성모의 파괴점막의 궤양, 부종과 염증소견 등이 심하게 관찰되었다. 그러나 산도가 약할수록, 그리고 펩신이 첨가되지 않은 합성위액으로 관류한 군에서는 섬모 및 점막의 손상이나 염증 및 부종등의 소견이 경미하게 관찰되었다. 이러한 결과로 미루어 강한 산도의 위액이 후두 및 기관으로 역류될 경우 협착증의 발생에 깊이 관여하리라고 추측되었다.

The purpose of this study is to suggest environmental guidelines for the conservation of ceramics excavated from underwater. Accordingly, the conditional change of the soluble salt on surface of the excavated ceramics was examined by changing the relative humidity. Examining the relative ratio [high humidity(RH70%+RH80%)/low humidity(RH20%+ RH40%)] for 24 weeks using accumulated conductivity(${\mu}s/cm$), the result showed that the amount of ion elution increased more in high humidity than in low humidity. In particular, the ion elution increased significantly within the celadon sample. In addition, comparing the accumulated conductivity and physical characteristics of the samples in high humidity, the results indicated that the amount of the ion elution is proportioned to the increased rate of the sample's absorption capacity and porosity. Ceramics excavated from underwater has risks of the secondary physical and chemical attacks from remaining salts. Therefore, it is suggested these ceramics be stored in a storage which maintains proper temperature and low humidity conditions. Also, the collections need to be pre-classified according to the properties of the materials.

The purpose of this paper is whether or not the in-situ restoration of the reverse osmosis (RO) membranes which its membrane function is lost is possible. The damaged RO membranes are double coated through the salting-out method by the poly(styrene sulfonic acid) sodium salt as the cationic exchange polymer and the polyethyleneimine as the anionic exchange polymer and also conducted the opposite order of the coating materials. And according to the concentration, time and ionic strength, the flux and rejection are measured for the coated membranes. Then the best coating condition is to apply for the RO membrane module of the household water purifier to know the possibility of the in-situ restoration for the commercial module. When the condition of the PEI 30,000 ppm (IS = 0.1)/PSSA 20,000 ppm (IS = 0.7) is applied, the rejection was enhance from 69% for the damaged module to 86% (90% for the pristine module).

Purpose: The aim of this study is to investigate anti-arthritis activity using natural eggshell membrane (NEM). Methods: NEM was administered at 52 mg/kg, 200 mg/kg, and 400 mg/kg to SD-Rat, where arthritis was induced by monosodium iodoacetate (MIA) at 3 mg. NO production in serum was measured using Griess reagent. Cytokines including IL-$1{\beta}$, and IL-6 were measured by Luminex and $PGE_2$, MMP-2, MMP-9, TIMP-1, $LTB_4$, and hs-CRP were measured by ELISA. The cartilage of patella volume was examined and 3-D high-resolution reconstructions of the cartilage of patella were obtained using a Micro-CT system. Results: Production of NO, IL-$1{\beta}$, IL-6, $PGE_2$, MMP-2, MMP-9, TIMP-1, $LTB_4$, and hs-CRP in serum was decreased, respectively, in comparison with control. The cartilage of patella volume increased significantly. In addition, the NEM group showed a decrease in the cartilage of patella, synovial membrane, and transformation of fibrous tissue. Conclusion: The results for NEM showed significant anti-arthritis activity. These results may be developed as a raw material for new health food to ease the symptoms mentioned above.

완전히 발육된 하악 제3대구치가 매복되어 있거나 또는 부분적으로 맹출된 상태일때는 임상증상을 일으키기 전에 발치하는 것이 치관주위염이나 이로 인한 합병증 및 치주질환 등을 예방할 수 있느느 가장 좋은 방법이며 이미 임상 증상을 유발한 매복 하악 제 3대구치는 대부분 재발방지를 위하여 발거하게 된다. 성공적인 발치의 기준을 1) 치아의 완전한 발치 2) 인접조직에 대한 최소한의 외과적 손상 3) 술후 합병증의 극소화 4) 가능한한 시술 시간의 단축 등이라 할때 매복 하악제 3대구치의 성공적인 발거를 위하여는 발치의 기본 원칙을 숙지하여야 함은 물론이며 더욱 면밀한 술전 평가와 외과적 발치술 시 필요한 기구의 완비 등이 필수적이라 할 것이다.

견갑하근의 단독 파열은 드물고 또 이에 대한 치료와 관련된 논문도 한정적이었으나 최근 관절경 술식의 발달로 견갑하근 파열의 진단과 치료방식이 발전하고 있다. 이러한 관점에서 견갑하근의 중요성이 더욱 대두되었고 이에 견갑하근의 파열양상, 봉합방법 그리고 후상방회전근 개 파열과의 관련성 등이 여러 저자들에 의해서 연구 되고 있다. 즉, 이전까지 관심의 대상에서 제외 되었던 견갑하근의 부분파열이 점차적으로 회전근 개 파열의 중요한 역할을 하며 상완 이두건초염과 오구상완 인대의 내측활차의 손상이 이러한 부분파열의 원인을 제공할 수 있음을 알 수 있다. 그러나 견갑하근 파열에 대한 정확한 원인 인자는 아직 불투명하다.
