The purpose of this study is to investigate what character elementary teacher's beliefs and attitudes about mathematics affect mathematics teaching practices in school. For this goal : (1) Designing questionnaire to measure elementary teacher's beliefs and attitudes about mathematics (2) Inquiring into character of elementary teacher's beliefs and attitudes about mathematics after analyzing questionnaire (3) Analyzing two teachers' mathematics teaching practices to understand how teacher's beliefs and attitudes affect mathematics teaching practices As a result of questionnaire analysis, beliefs about mathematical essence is between 'yes and no' and 'generally yes', beliefs about mathematics learning is near 'generally yes', beliefs about mathematics teaching is between 'yes and no' and 'generally yes', and beliefs about mathematics teaching practices inclines to 'generally yes'. The analysis of mathematics teaching practices shows that teacher's beliefs and attitudes about mathematics influence organizing and developing contents of instruction. Teacher L thinks that the important purpose of teaching mathematics is to develop problem solving skill of students and to help students to think mathematically. Teacher L's beliefs about mathematics teaching shows that L gives student-centered lessons and takes a role as a helper. Teacher K thinks that the teacher has to use more ways to teach one concept and to explain in detail. Teacher K's beliefs and attitudes about mathematics teaching show that K uses pictures, concrete materials or examples to explain in detail.

The pluralism of the contemporary architecture is an environment to solve the problems presented the criticism of the Modern Movement and a mechanism to get a new standard of value with the transformation of the Modern Architecture's ethical concept into the problem of meaning. Contextualism, A methodology of architectural conditions, is represented in two ways such as the philosophical and the historical movement in architecture. It's methodology of building solution has been found from the urbanic field. The main problems in architecture are understood as urban structures in which cities have their own inner logics. The asthetic characteristics of the elements in the urban space are considered as physical structures. Contextualists concern the special building, architecture synthetically rather than analytically about modern cities and architecture, and develop the theme of modern cities broadly. European rationalists whose profects the ornamental properties are found from, have synthesized organic architecture with 1920s' rationalism and represented modern rationality.

The crown-root fracture is defined as a fracture of tooth that contains enamel, dentin and cementum with or without pulp exposure. Generally the fracture lines place obliquely from labial surface, between incisal edge of the crown and marginal gingiva, to palatal surface subgingivally. If the fracture line is located supragingivally, the removal of tooth fragment and supragingival restoration can be performed. In subgingival fracture line, the surgical exposure, orthodontic eruption or surgical eruption can be considered. If the fracture line is too deep to restorate, extraction or decoronation can be selected. In children and adolescents, the extraction should be the last option. Another option to select before extraction is the restoration using fiber-reinforced post and the reattachment of tooth fragment. The fiber-rainforced post enhances the retention and the durability of tooth fragment. The reattachment of crown fragment using resin adhesive system is considered minimal invasive treatment biologically. This case reports the treatment of crown-root fracture using the reattachment of crown fragment and the insertion of fiber-reinforced post. 치관-치근 파절은 법랑질, 상아질, 백악질이 모두 포함된 치아의 파절로, 파절선이 대부분 절단연이나 순측의 변연부 치은 에서 구개측 치은열구 하방으로 사선으로 진행된다. 파절선의 위치가 치은 연상이라면 파절편의 제거 및 치은연상 수복을 시 행하고, 치은 연하라면 파절면의 외과적 노출술, 교정적 정출술, 외과적 정출술을 이용한 치아의 수복이 이루어진다. 그 외에 섬유 강화형 포스트를 삽입하여 치관 수복물의 유지력을 높이고, 레진 접착 시스템을 사용하여 치관 파절편을 재부착함으로 써 생물학적으로 최소한으로 침습적인 치료를 하는 방법도 있다. 만약 파절의 정도가 치은 연하로 깊은 경우 발치나 치관절제 술을 이용한 치근의 유지 등을 고려할 수 있다. 본 증례는 치관-치근파절로 내원한 12세 환아로 섬유강화형 포스트를 사용하여 치관 파절편 재부착을 시행하였으며 양호 한 경과를 보여 이를 보고하는 바이다.

In the view of the results investigated the effect of air pollutants that is emitted from a new generator facilities, the total estimated concentration which is the summation of a contributional concentration and observational concentration is much less than that of atmospheric environment criterion for the air pollutants. So we can predict that the operation of the new generator facilities with mitigation equipment don't seriously affect around environment. At the same time, we compared the contributional concentration of before mitigation equipment with that of after it to examine the decreasing amount due to mitigation equipment. The result showed that the concentration of SO2, NO2 and PM-10 is reduced to 25%, 30% and 26% of original value, respectively.

For digitizing Hangul Tripitaka which is a Korean version of the Tripitaka Korean, we can input, store the retranslated archaic documents in database, and search their contents through the Internet. Because the archaic documents of Hangul Tripitaka includes extension characters of Chinese origin, missing characters and special characters, we input and store documents use Unicode and make image fonts that cannot be represented by Unicode. Also, for developing retrieval system in this research, we use MS-SQL 7.0 and IIS(Internet Information Server) on Windows 2000 Server. By developing search engine which provides variety of retrieval methods, people who concern the archaic documents in the whole world can access Hangul Tripitaka saved as Unicode using the Web.

The Role of Thymic Stromal Lymphopoietin (TSLP) in Glomerulonephritis

Lee, Keum Hwa,Yang, Jae Won,Cho, Jin Young,Lee, Joo Yup,Lim, Eun Kyung,Eisenhut, Michael,Jeong, Dong Yeon,Steingroever, Johanna,Shin, Jae Il Korean Society of Pediatric Nephrology 2018 Childhood kidney diseases Vol.22 No.1

Thymic stromal lymphopoietin (TSLP) is an interleukin-7-like cytokine that is an important trigger and initiator of many allergic diseases. TSLP promotes a T-helper type 2 (Th2) cytokine response that can be pathological. A relationship is formed both at the induction phase of the Th2 response through polarization of dendritic cells to drive Th2 cell differentiation and at the effector phase of the response, by promoting the expansion of activated T cells and their secretion of Th2 cytokines and TSLP. In transgenic mice with TSLP overexpression, it has been reported that TSLP leads to the development of mixed cryoglobulinemic membranoproliferative glomerulonephritis. In addition, TSLP can play an important role in the pathogenesis of IgA nephropathy and systemic lupus erythematosus-related nephritis. From our knowledge of the role of TSLP in the kidney, further studies including the discovery of new therapies need to be considered based on the relationship between TSLP and glomerulonephritis.

Purpose: Podocytes are important architectures that maintain the crucial roles of glomerular filtration barrier functions. Despite this structural importance, however, the mechanisms of the changes in podocytes that can be an important pathogenesis of minimal change nephrotic syndrome (MCNS) are not clear yet. The aim of this study was to investigate whether apoptosis is induced by interleukin (IL)-13 in cultured human podocytes. Methods: Human podocytes were treated with different IL-13 doses and apoptotic cells were analyzed using terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL assay) and fluorescence-activated cell sorting (FACS). Results: The IL-13 increased the number of TUNEL-positive cells in a dose-dependent manner at 6 and 18 hours (P<0.05 and P<0.05, respectively). The apoptosis rate was appeared to be increased slightly in the IL-13-stimulated podocytes (8.63%, 13.02%, and 14.46%; 3, 10 and 30 ng/mL, respectively) than in the control cells (7.66%) at 12 hours by FACS assay. Conclusion: Our study revealed that IL-13 expression may increase podocyte apoptosis. Blocking the IL-13 signal pathway can potentially play an important role in regulating the apoptosis of podocytes.

Lee, Keum Hwa,Hong, Sung Hwi,Jun, Jinhae,Jo, Youngheun,Jo, Woogyeong,Choi, Dayeon,Joo, Jeongho,Jung, Guhyun,Ahn, Sunghee,Kronbichler, Andreas,Eisenhut, Michael,Shin, Jae Il The Korean Pediatric Society 2020 Clinical and Experimental Pediatrics (CEP) Vol.63 No.5

IgA vasculitis, formerly known as Henoch-Schönlein purpura, is a systemic IgA-mediated vasculitis of the small vessels commonly seen in children. The natural history of IgA vasculitis is generally self-limiting; however, one-third of patients experience symptom recurrence and a refractory course. This systematic review examined the use of dapsone in refractory IgA vasculitis cases. A literature search of PubMed databases retrieved 13 articles published until June 14, 2018. The most common clinical feature was a palpable rash (100% of patients), followed by joint pain (69.2%). Treatment response within 1-2 days was observed in 6 of 26 patients (23.1%) versus within 3-7 days in 17 patients (65.4%). Relapse after treatment discontinuation was reported in 17 patients (65.4%) but not in 3 patients (11.5 %). Four of the 26 patients (15.4%) reported adverse effects of dapsone including arthralgia (7.7%), rash (7.7%), and dapsone hypersensitivity syndrome (3.8%). Our findings suggest that dapsone may affect refractory IgA vasculitis. Multicenter randomized placebo-controlled trials are necessary to determine the standard dosage of dapsone at initial or tapering of treatment in IgA vasculitis patients and evaluate whether dapsone has a significant benefit versus steroids or other medications.

Background: The purpose of the study is to evaluate the impact of rapid response team (RRT) activity during the post-operative period. Methods: From Mar 2014 to Dec 2014, a total of 1171 patients were electronically screened during the post-operative period for at least 24 hours in departrment of orthopedic surgery, St. Mary`s hospital. Among them, 1129 were discharged without serious adverse events (SAEs), 30 were activated by requests of attending doctors or nurses or the electronic medical alert system and 12 had SAE without RRT activation. We compared the clinical characteristics and progress of 30 activated and 12 non-activated patients by retrospective chart review. Results: The most common SAE was pulmonologic origin in activated patients. Mean modified early warning scores (MEWS) at admission and post-operative day 1 (POD 1) were higher in activated patients (2.3 vs. 1.08, P = 0.009 / 2.4 vs. 0.8, P = 0.000), but APACHE II score at POD 1 were not statistically different (8.4 vs. 10.5, P = 0.146). The percentage of CPR and mortality were higher in non-activated group (13.3% vs. 25%, P = 0.063, 10% vs. 41.7%, P = 0.031). Conclusion: At-risk patients with higher MEWS at admission and POD1 were prone to activate RRT and be undertaken successful intervention during the postoperative period. But the patients who were not detected by electronic medical alert system or attending physician showed higher rate of CPR and mortality. Further development of postoperative screening system would be needed.
