This research was performed to find out the adaptation patterns of maxillary and mandibular posterior teeth to the changes in relationships of vertical skeletal components, which constitute the skeletofacial complex. For this research, 61 adult malocclusion patients were chosen as subjects according to the Hellman's dental age with normally ranged FMN-A-B angle. These subjects were divided into 4 groups in maxilla and 3 groups in mandible according to mesiodistal inclinations of teeth. Following results were obtained after studying the relationships of the vertical skeletal components between each group. 1. Inspite of the fact that the FMN-A-B angle was within a normal range, the degree of mesiodistal inclinations of maxillary and mandibular posterior teeth showed differences in relation to the anteroposterior relationships of maxilla and mandible. In case where the FMN-A-B angle was large, the mesial inclinations of maxillary posterior teeth showed more increase from the posterior to the anterior, whereas in mandible it showed overall decrease. 2. The degrees of mesial inclinations of mandibular posterior teeth were increased when the angulations of lower facial height, occlusal plane angle and mandibular plane angle were greater. 3. The patterns of mesial inclinations of maxillary posterior teeth were varied according to the angulation of lower facial height. If relatively large, it showed more increase from the posterior to the anterior and it was decreased nearly consistent when the angulation was small. 4. The degrees of mesial inclinations of maxillary posterior teeth were decreased as the lower facial height, palatal plane angle, occlusal plane angle and the mandibular plane angle became greater.

본 연구의 목적은 이산화게르마늄을 함유한 게르마늄 용질액을 자돈에 급여하였을 때 성장 및 혈액학적 변화에 미치는 영향을 조사하기 위하여 실시하였다. 3원 교잡종 자돈 60두 (평균체중 11.22±0.10㎏)를 공시하였다. 시험설계는 옥수수-대두박 위주의 대조구(CON)와, 대조구 사료내 게르마늄 용질액을 0.5 ppm 첨가한 구(GC0.5) 및 대조구 사료내 게르마늄 용질액을 1.0 ppm 첨가한 구(GC1.0)로 3개 처리를 하였다. 0-10일간 사양시험기간동안, 일당증체량에 있어서 GC0.5 처리구가 약간 높게 평가되었다(quadratic effect, P<0.02). 그러나 전체 시험기간동안, 일당증체량, 일당사료섭취량 및 사료효율에 있어서 처리구간에 유의적인 차이는 보이지 않았다. 영양소 소화율에 있어서는 GC0.5 처리구가 조회분(linear effect, P<0.01; quadratic effect, P<0.04), 칼슘(linear effect, P<0.01; quadratic effect, P<0.01), 인 (linear effect, P<0.02; quadratic effect, P<0.04) 소화율이 유의적으로 높게 평가되었다. 혈액내 neutrophil 농도에 있어서는 게르마늄 용질액의 첨가 수준이 증가함에 따라 유의적으로 증가하는 경향을 나타내었다(quadratic effect, P<0.02). 결론적으로, 자돈 사료내 게르마늄 용질액의 급여가 성장 및 혈액학적 수치에는 영향을 미치지 못하는 것으로 사료된다. This study was conducted to investigate the effects of dietary germanium colloid on the growth performance and hematological values in nursery pigs. Sixty pigs (11.22(0.10 ㎏ average initial body weight) were used in a 20 d growth assay. Dietary treatments included 1) CON (basal diet), 2) GC0.5 (basal diet+0.5 ppm germanium colloid) and 3) GC1.0 (basal diet+1.0 ppm germanium colloid). For d 0 to 10, pigs fed GC0.5 diet grew faster than pigs fed CON and GC1.0 diets (Quadratic effect, P<0.02). However, through the entire experimental period, no statistical differences were found for aver-age daily gain, average daily feed intake and gain/feed. Apparent digestibilities of crude ash (Linear effect, P<0.01; Quadratic effect, P<0.04), calcium (Linear effect, P<0.01; Quadratic effect, P<0.01) and phosphorus (Linear effect, P<0.02; Quadratic effect, P<0.04) in pigs fed GC0.5 diet were greater than for pigs fed CON and GC1.0. Neutrophil concentration in blood increased as the concentration of germanium colloid in the diets was increased with significant difference (Quadratic effect, P<0.02). In conclusion, growth performance and hematological values were not influenced by dietary germanium colloid.

홍지숙,김대성,오경민,김윤지,이규홍,박양호 대한치과교정학회 2010 대한치과교정학회지 Vol.40 No.3

Objective: The aim of this study was to evaluate the volumes and areas of the upper airways in children with Class II malocclusion, using three dimensional cone-beam computed tomography (CBCT) and to compare the volumetric and cross-sectional measurements and cephalometric variables to investigate possible relationships between the upper airway and facial morphology. Methods: CBCT scans were obtained from 37 subjects (17 boys and 20 girls; average age, 11.02 years). The upper airway volumes and areas were measured, and compared with cephalometric variables. Results: The area of the PNS-posterior plane (SPP) was significantly smaller in the Class II malocclusion group (p < 0.05). Also, the volumetric and cross-sectional measurements were lower in Class II than in Class I malocclusion groups, although the differences were not significant between the two groups (p > 0.05). The Class II malocclusion group showed significantly smaller values of PFH, mandibular body length, pog to N perp and showed larger values of FMA, ANB, and facial convexity than the Class I malocclusion group. The volume of the upper airway in front of PNS point (WN) showed negative correlation with ANB (p < 0.05). Conclusions: The Class II malocclusion group had a narrower upper airway associated with a decreased posterior facial height and a divergent growth pattern than the Class I malocclusion group. 성장기 아동의 상기도 협착은 두개안면 성장에 영향을 미칠 수 있다. 본 연구는 3차원 cone-beam computed tomography (CBCT)를 이용하여 제II급 부정교합 아동의 상기도 부피 및 단면적 계측치와 측모두부계측치를 비교하여 상기도와 안면 형태와의 연관성을 알아보고자 하였다. 37명의 아동(남자 17명, 여자 20명, 평균 연령 11.02세)의 CBCT를 촬영하였다. 연구 결과, 상기도의 PNS-posterior plane에서의 단면적(S_(PP))은 제II급 부정교합군에서 유의하게 작았다 (p < 0.05). 상기도 부피 계측치는 제II급 부정교합군에서 제I급 부정교합군보다 작았으나, 두 군 간 통계적으로 유의한 차이는 없었다. 제II급 부정교합군은 후안모고경(PFH), mandibular body length (p < 0.05), Pog to N perp (p < 0.01)에서 제I급 부정교합군보다 유의하게 작은 값을 보였고, FMA (p < 0.05), ANB, facial convexity (p < 0.01)는 유의하게 큰 값을 보였다. 제II급 부정교합군의 PNS 전방의 상기도 부피(W_(N))는 ANB difference 각도와 음의 상관관계를 보였다 (p < 0.05). 제II급 부정교합 아동은 상대적으로 좁은 상기도 부피를 가지며 이에 따른 감소된 후안모고경(PFH)과 하악골의 divergent한 안면 성장 양상을 보였다.

( Hye Kyung Song ),( Kang-moon Lee ),( Sung-ae Jung ),( Sung Noh Hong ),( Dong Soo Han ),( Suk-kyun Yang ) 대한장연구학회 2016 Intestinal Research Vol.14 No.3

Background/Aims: The quality of care in inflammatory bowel disease (IBD) has not been systematically estimated. The aim of this study was to investigate the current status of quality of IBD care in Asian countries. Methods: A questionnaire-based survey was conducted between March 2014 and May 2014. The questionnaire was adopted from “An adult inflammatory bowel disease physician performance measure set” developed by the American Gastroenterological Association. If the respondent executed the performance measure in more than 70% of patients, the measure was regarded as well performed. Results: A total of 353 medical doctors from Asia completed the survey (116 from Korea, 114 from China, 88 from Japan, 17 from Taiwan, 8 from Hong-Kong, 4 from India, 3 from Singapore, and 1 each from the Philippines, Malaysia and Indonesia). The delivery of performance measures, however, varied among countries. The documentation of IBD and tuberculosis screening before anti-tumor necrosis factor therapy were consistently performed well, while pneumococcal immunization and prophylaxis of venous thromboembolisms in hospitalized patients were performed less frequently in all countries. Physician awareness was positively associated with the delivery of performance measures. Variations were also noted in reasons for non-performance or low performance of quality measures, and the two primary reasons cited were consideration of the measure to be unimportant and lack of time. Conclusions: The delivery of performance measures varies among physicians in Asian countries, and reflects variations in the quality of care among the countries. This variation should be recognized to improve the quality of care in Asian countries.
