  • Apartment houses, the representative type of urban housing, are becoming an important element in Korea urban landscape. In this regard, this study aims to consider landscape in view of city residents reflecting human's visual perceptual characteristic, and in line with this, the urban landscape of apartment houses viewed from the urban center main intersections has been embodied according to the physical components of the intersections, which was followed by preference survey of the city residents, and then based on this, the visual-perceptual characteristics were examined. The findings are as follows: 1. The findings gained from the average of the landscape types indicate that the city residents are more satisfied when the shielding by surrounding buildings is minimized, view securing is relatively good, the whole complex is clearly observed because of its proximity to the visual point, and the view of the complex is well recognized from the focus point. 2. The examination concerning the preferred factors positively evaluated in terms of architectural planning shows that when the complex view is changeable sophisticated, makes the residents feel comfortable with its stable, open plan, and it's in harmony with surroundings, such housing attracts the city residents. 3. In terms of architectural planning factors, it turned out that the complex is more preferred when the visibility of the complex and the scale of surrounding green space are in good condition, and such elements of the complex as the sky line, the overall shape, the elevation, variation of the shape and height are harmonious with one another.

  • Proximal humerus fracture can be defined as a fracture that occurs in the surgical neck or proximal part of the humerus. Despite the appropriate treatment, however, various complications and sequelae can occur, and the treatment is quite difficult often requiring surgical treatment, such as a shoulder replacement. The classification of sequelae after a proximal humerus fracture is most commonly used by Boileau and can be divided into two categories and four types. Category I is an intracapsular impacted fracture that is not accompanied by important distortions between the tuberosities and humeral head. An anatomic prosthesis can be used without greater tuberosity osteotomy. In category I, there are type 1 with cephalic collapse or necrosis with minimal tuberosity malunion and type 2 related to locked dislocation or fracture-dislocation. Category II is an extracapsular dis-impacted fracture with gross distortion between the tuberosities and the humeral head. To perform an anatomic prosthesis, a tuberosity osteotomy should be performed. In category II, there are type 3 with nonunion of the surgical neck and type 4 with severe tuberosity malunion. In type 1, non-constrained arthroplasty (NCA) without a tuberosity osteotomy should be considered as a treatment. On the other hand, reverse shoulder arthroplasty (RSA) should be considered if types 1C or 1D accompanied by valgus or varus deformity or severe fatty degeneration of the rotator cuff. In general, the results are satisfactory when NCA is performed in type 2 sequelae. On the other hand, RSA can be considered as an option when there is no bony defect of the glenoid and a defect of the rotator cuff is accompanied. In type 3, it would be effective to perform internal fixation with a bone wedge graft rather than shoulder replacement arthroplasty. Recent reports on the results of RSA are also increasing. On the other hand, recent reports suggest that good results are obtained with RSA in type 3. In type 4, RSA should be considered as a first option.

  • Purpose : We performed this study to evaluate the diagnostic usefulness of endoscopic finding of nodular gastritis, CLO and HpKit test for H. pylori infection in children. Methods : Gastroduodenal endoscopy and mucosal biopsy were performed on 212 children who visited our hospital between Jul. 1999 and May 2000 due to abdominal pain. We performed CLO and HpKit test for H. pylori with the time interval of 15, 30 minutes, 1, 2, 3, 24, 48, 72, 96, 120 and 144 hours. Histological examination of H. pylori was made by H-E or Alcian yellow stain with biopsy specimens. Sensitivity, specificity, positive predictive and negative predictive value of nodular gastritis, CLO and HpKit test were calculated from the analysis of above data. Results : Sensitivity and specificity of 3 hour-CLO test was 68.4% and 100% respectively. Sensitivity and specificity of 3 hour-HpKit test was 65.8% and 100% respectively. No significant difference in sensitivity and specificity was found between in 3 hour-CLO and HpKit test(P>0.05). Sensitivity of CLO test increased as time lapsed, but corresponding specificity did not decrease as time lapsed(sensitivity and specificity at 144 hours : 89.5% and 94.8% respectively). However, sensitivity of HpKit test increased as time lapsed, but specificity markedly decreased. Sensitivity and specificity of the nodular gastritis was 78.9% and 93.7% respectively. Conclusion : Both CLO and HpKit test have relatively low sensitivity and specificity for the detection of H. pylori in 3 hours of testing in children. The endoscopic finding of nodular gastritis is another good standard in the diagnosis of H. pylori infection in children.

  • 저수준레에저요법에 대해서는 지난 10여년간 의학계 및 치과계에서 임상적으로 사용하여 좋은 결과가 있다고 많은 보고가 발표되고 있다. 특히 치근의 골결손에 관한 연구에서는 전기요법, 초음파요법, 전자장요법 등 뿐만아니라 저수준레이저를 사용하여 골절부내 Callus형성이 촉진되었음을 보고하고 새로운 치료법의 하나가 될 수 있음을 제안한 바도 있다. 본 연구에서는 칼륨비소를 다이오드로 사용한 저수준레이저조사가 골결손의 치유에 어떠한 영향을 미치는지 확인하고자 골모세포의 알칼리성 인산분해효소의 활성화와 석회화결절의 형성을 평가함으로 골모세포의 기능을 조사코저하였다. 실험은 첫째, 9개군으로 나누어 레이저 조사기간에 따른 알칼리성 인산분해효소의 활성화를 조사하였고, 둘째, 이를 근거로 9일간 계속 매일 1회 1.3 J/cm2의 레이저를 조사한 후 펄스의 종류별 차이를 비교하였으며, 세째,레이저펄스별 석회차 결절의 형성 정도를 광학현미경으로 관찰하여 비교분석하였다. 결과, 7일 계속 레이저를 조사한 경우 다른 군에 비해 서서히 ALP의 활성이 증가하였으나 유의한 차이는 없었으며. 따라서 9일동안 레이저를 계속 조사한 경우에는 전체 에너지량이 5.895 J/cm2 인 펄스13과 15가 뚜렷하게 유의한 증가를 보여주었다. 그러나 석회화결절의 형성은 전체 에너지량이 2.546 J/cm2 인 펄스11에서 가장 많았다. 결론적으로 골형성이나 알칼리성 인산분해효소의 활성을 촉진하는 데에는 적절한 레이저 조사조건이 필요하나, 알칼리성 인산분해효소의 활성을 촉진한 펄스와 석회화결절의 형성을 촉진하는 펄스가 서로 다르게 나타난 것은 골형성을 촉진하는 여러요인 들이 저수준레이저에 자극받았을 가능성이 높음을 보여준다 이러한 결과들로 보아 저수준레이저는 골모세포의 기능을 자극하여 골결손의 치유를 개선하는 데 도움될 것이라 사료된다.다. 각 백서의 양측 창상중 하나는 1,3,5,7일 마다 각 실험의 방법에 따라 레이저를 조사하고 실험동물의 다른 창상은 대조군으로서 사용하였다. 모든 창상의 면적은 실험 1,3,5,7 일째에 일정한 거리에서 사진촬영하여 면적계를 이용, 측정한 후 통계적인 의의를 조사하였다. 본 연구의 결과는 저수준레이저는 특정 조건하에서 S. aureus의 증식을 촉진하였다. 그러나 S. aureus에 감염된 창상을 저수준레이저로 조사시 치유가 촉진되었다. 중앙 조사법고 주변조사법에 의한 창상치유효과는 통계적인 의의가 보이지 않았다. 따라서 결론적으로 S. aureus 에 감염된 창상에 직접 또는 간접적이든 pulse의 종류에 관계없이 조사하는 경우 치유효과가 나타나는 것은 정사주위 조직의 LLLI 자극효과가 염증의 확산을 억제한다고 말할수 있다.4/1$0^{\circ}C$에서는 Shoa-Nan-Tsan과 Lenkwang이 가장 높았으며 백앙벼는 3 온도 조건 모두에서 활성이 낮았다. 발아소요일수와 amylase 활성과는 유의적인 정의 상관관계를 보였다., 다다조, 미국의 건답직파재배 품종 등이었으며 우리 나라 육성종들은 모두 지중에서 신장이 멈추어 제1본엽이 지중에서 추출하였으며, Scm파종심에서 불완전엽이 지면을 뚫고 나오는 품종은 Chinsura Boro뿐이었고 Nato, Labelle, Weld Pally, Italliconaverneco 등도 지면 가까이 까지 신장하였다. 6. 50% 출아일수는 제2절간장을 제외 한 모든 유아 형질의 신장도와 유의한 부의 상관을 보였는데 가장 높은 상관을 보인 것은 중배축장+제1절간장+불완전옆장이었으며, 다음이 불완전엽장이 었다. 7. 출아율은 중배축장+제1절간장+불완전엽장, 중배축장+초엽 장과 모든 파종심에서 높은 정의 상관을 보여 제1본엽의 추출 위치가 높을수록

  • Implant placement in the anterior region is performed in several stages, and harmonization of both hard and soft tissues is essential. In addition, adequate esthetic and functional evaluations are necessary in the process of transitioning from the provisional to the final prosthesis to attain patient satisfaction. Although gingiva can be molded in the anterior region, depression in the occlusal view can yield good results through the augmentation procedure. However, the harvesting of connective tissue from the palate is not suitable for various reasons, such as postoperative discomfort and intraoperative bleeding. Compared to the palatal area, the harvesting of connective tissue from the maxillary tuberosity can easily result in relatively thick tissue and quick healing of the donor site, thus proving to be a good modality for graft procedures. The purpose of this report is to examine the relevant evidence from previous studies and evaluate the process of soft tissue augmentation through a case presentation.

  • 안장은 인체하중이 집중되고, 자전거의 충격과 진동이 직접 전달되는 부위로서 주행 안락도를 높이고 buttock의 discomfort를 감소시킬 수 있도록 설계되어야 한다. 본 연구의 목적은 인체곡면을 본뜬 안장형상 설계를 통하여 buttock의 국부적 discomfort를 감소시키고자 하는 것이다. 인간의 앉은자세에 대한 해부학적 고찰을 통해 좌골결절(Ischial Tuberosity)과 치골결합면(Symphyseal Surface)이 안장과 직접 맞닿는 면으로 파악되었으며, 이들 부위에 대한 집중적 개선이 이루어져야 할 것으로 제안되었다. 문헌조사를 통해 의자설계시 고려해야 할 인체치수 및 지침을 파악하였으며, 안장과 의자의 기능비교를 통해 이를 선별적으로 적용하였다. 인체곡면 측정을 위해 Rod Matrix(3cm 간격, 13*20)방법을 이용하여 10명의 buttock contour를 측정하였으며, 측정된 자료를 분석하여 안장의 곡면형상을 결정하였다. General Comfort Rating, Body Part Discomfort 등의 주관적 안락도 평가방법을 통하여 기존 자전거 안장과 본 연구를 통해 개발된 안장을 비교 평가한 결과, 전반적인 안락도의 향상과 좌골결절 및 치골 결합부의 discomfort 감소효과를 가져온 것으로 파악되었다.

  • Background: Lectins are proteins or glycoproteins of non-immune origin that recognize a specific sequence of sugar residues. The availability of a large number of lectins has provided the capacity to identify selectively glycoconjugates possessing distinctive chemical structure in diverse sites of highly specialized biological activity. The purpose of the present study was to investigate the lectin binding patterns of various components in human pulmonary tubercles. Method: Biopsy specimens of tuberculous lung were obtained from male adult patients who underwent a surgical resection for severe pulmonary tuberculosis. The specimens were processed and stained with 13 kinds of biotinylated lectins according to some modification of Hsu and Raine's methods. Results: 1) In the caseous necrotic lesions, BS $I-B_4$ showed negative reaction and BS I were also negative except some irregularly-shaped cells located in the marginal zone. All other lectins, however, showed a positive reaction with various binding patterns. 2) The epithelioid cells were broadly divided into three groups according to the reaction patterns in the cytoplasms and cell membranes. 3) WGA, ECL, PHA-L, PHA-E and LCA showed strong staining in the lymphocytes. 4) SBA showed a different binding patterns between the endothelial layers located in the region beyond the fibrous layers and those located within the fibrous layers. 5) PNA showed a positive reaction in the outer 1/3 to 1/2 of the fibrous layer, but showed no staining in the inner 1/2 to 2/3 of the fibrous layers. Conclusion: The present lectin histochemical study provided a useful information to assess the characterization and distribution of various glycoconjugates in each constituent of human pulmonary tubercles. The results demonstrate structural differences in the glycoconjugate composition of various components of the tubercles and reveal changes in glycosylation in the components during soft tubercle formation. This study provides a new data useful for the studies on the pathogenesis and pathology of human pulmonary tubercles.
