구치부 지지의 상실로 인해 과도한 치아 마모와 수직 고경 상실을 보이는 환자에서 수직 고경 거상을 동반한 전악 수복 증례

정지아,방주혁,이용상,김성용,Jung, Ji-Ah,Bang, Joo-Hyuk,Lee, Yong-Sang,Kim, Sung-Yong 대한치과보철학회 2020 대한치과보철학회지 Vol.58 No.2

증령에 따라 진행되는 치아의 마모는 자연스러운 현상이지만 생리적인 범위를 초과하여 나타나는 병적 마모는 기능 및 심미 문제를 야기하게 된다. 특히, 구치부 지지가 상실되면 전치부의 병적 마모로 인해 수직 고경의 감소와 교합평면의 부조화가 일어날 수 있다. 이러한 문제를 해결하려면 중심위를 고려한 적절한 수직 고경 설정이 필요하다. 본 증례의 환자는 상악 구치부 상실에 의한 하악 전치부의 심한 마모를 보이는 71세 남환으로 보철 수복 공간을 위해 수직 고경을 거상하여 전악 수복을 시행하였다. 8개월간의 평가 결과 안정적인 교합을 확인하였고 기능적, 심미적으로 만족할만한 결과를 보였기에 이를 보고하고자 한다. Gradual tooth wear is a natural process of aging, but pathological wear over physiologic ranges leads to functional and esthetic problems. The loss of posterior support may cause pathological wear of anterior teeth, which results in reduction of vertical dimension and disharmony of occlusal plane. To solve this problem, determination of proper vertical dimension considering centric relation is necessary. This case report presented 71-year-old male, who had the severe wear of lower anterior teeth due to loss of posterior support. By meticulous evaluation, a full mouth rehabilitation with elevation of vertical dimension was planned. After 8 months of follow-up, stable occlusal scheme is maintained and patient was satisfied with clinical outcome functionally and esthetically.

Because Moyers' method is developed for Caucasians. use of Moyers' method in korea is not suitable for estimating and gaining the space of unerupted permanent canine and premolars. The purpose of the present study was to determine which sum or combination of sums of permanent tooth widths presented the best prediction capability for the canine and premolar sums in a Korean sample. The dental casts of 71 koreans children with permanent dentition was measured to the nearest 0.05 mm with a three-dimensional computerized system. the two-way univariate analysis of variance (ANOVA) test and pearson correlation coefficient were used for the statical analysis. As for female. the combination of the sums of permanent lower lateral incisors and upper first molars showed the highest correlation with the sums of unerupted canine and premolar widths. Correlation varied according to dental arch and sex. If predictors with higher correlation value for each gender are used ‘ results will be more precise. In addition. mesiodistal tooth size measurement using the new virtual method is more simple and reliable.

가와사끼병과 특발성 혈소판 감소성 자반증 환아에서 고용량 정주용 면역글로불린의 신독성 유무

정지아,김혜순,서정완,이승주,Jung Ji Ah,Kim Hye Soon,Seo Jeong Wan,Lee Seung Joo 대한소아신장학회 1998 Childhood kidney diseases Vol.2 No.2

목 적 : 1987년 정주용 면역글로불린(Intravenous immunoglobulin: IVIG)에 의한 급성신부전의 첫 증례가 보고된 이후 성인에서는 고용량의 IVIG와 관련된 신손상의 보고들이 다수 있었다. 이에 저자들은 고용량 IVIG의 사용이 보편화되어 있는 가와사끼병과 특발성 혈소판 감소성 자반증 환아에서 IVIG의 신독성 여부를 관찰하고자 하였다. 방 법 : 1996년 1월에서 8월까지 이대 부속 목동 병원에 입원하여 가와사끼병(23례)과 특발성 혈소판 감소성 자반증(7례)으로 고용량의 정주용 면역글로불린(2 g/kg)을 투여받은 환아를 대상으로 하였다. IVIG투여후 1일, 3일에 요량, BUN, 혈청 creatinine, Ccr, FENa, TRP, 24 시간뇨 ${\beta}_2$-microglobulin/cr 비 및 microalbumin/cr 비의 변화를 관찰하였다. 통계는 repeated measurement ANOVA test와 t-test를 사용하여 검정하였다. 결 과 : 고용량의 IVIG 투여후에 요량, BUN, 혈청 creatinine, Ccr, TRP, 24 시간뇨 ${\beta}_2$-microglobulin/cr 비 및 microalbumin/cr비의 유의한 변화는 없었다. IVIG투여후 1일에 일시적으로 증가한 FENa만이 유의한 변화였다. 결 론 : 소아에서 흔히 사용되는 고용량 IVIG는 정상 신기능 상태에서는 유의한 신손상을 일으키지 않았다. Purpose : To investigate renal toxicity of high-dose intravenous immunoglobulin(IVIG) in children with Kawasaki disease and idiopathic thrombocytopenic purpura. Methods : 23 children with Kawasaki disease and 7 children with idiopathic thrombocytopenic purpura who were treated with high-dose IVIG(2 g/kg) were evaluated for the change of urine output, blood urea nitrogen(BUN), serum creatinine(Scr), creatinine clearance(Ccr), tubular reabsorption of phosphorus(TRP), fractional excretion of sodium(FENa), 24hour urine ${\beta}_2$-microglobulin/creatinine(${\beta}_{2}MG/cr$) ratio and urine microalbumin/creatinine(MA/cr) ratio at post-IVIG 1 and 3 day. Results : There was no significant change of urine output, BUN, Scr, Ccr, TRP, 24hour urine ${\beta}_{2}MG/cr$ and MA/cr ratio after high-dose IVIG treatment. Transient increase of FENa at post-IVIG 1 day was the only significant change. Conclusion : There was no significant renal toxicity of high-dose IVIG in children with Kawasaki disease and idiopathic thrombocytopenic purpura who had normal renal function.

Inequality of Human Capital Development in the Korean Labour Market, and its Effects on Korean workers’ Occupational Achievements

정지아,최석현,조창현 연세대학교(미래캠퍼스) 빈곤문제국제개발연구원 2013 地域發展硏究 Vol.22 No.1

The paper deals with institutions involved with workers’ human capital development and their influences on the Korean labour market. It reveals that Korea’s human capital development systems generate two human capital development paths for workers. The first path is for large-firm workers who maintain their career through continuous on-the-job training and renewing of their human capital. Another path is for small-firm workers, who do not have opportunities for human capital development because of their precarious working situations. The reasons for these segregated human capital development paths are: 1) the state’s neglect of its duties as regards to human capital development; 2) discrepancy in financial ability depending on firm sizes; 3)discriminative service from social protection; and 4) mismatch between the education and employment systems. All of these have important implications for policy makers as they strive to facilitate labour market integration.

Customer satisfaction is an ever-growing concern of management throughout the world. To find the way to increase customer satisfaction, we must understand customer requirements. Kano distinguishes between five types of customer requirements which influence customer satisfaction in different way when met. The objectives of this paper are to divide the quality of education service through the Kano Model. The concept was applied to A Airlines. In so doing, several satisfying and dissatisfying quality factors in education service were identified. Further, several academic and practical implication for education service were proposed.

Purpose : The purpose of this study was to determine the utility of serum prealbumin as a biochemical marker for nutritional adequacy in neonates. Methods : From March 1998 to May 1999, 71 fullterm(54 AGA, 9 LGA, 8 SGA) and 46 preterm neonates were enrolled. The correlations among prealbumin, albumin, birth weight and gestational age were obtained. Serum concentrations of albumin and prealbumin according to calory and protein intake were also serially measured in 30 fullterm and 29 preterm neonates on days 0, 3 and 7 of life. Results : Serum prealbumin concentrations at birth were 10.2±2.6mg/dL in fullterm AGA, 12.1±3.3mg/dL in fullterm LGA, 8.3±1.2mg/dL in fullterm SGA and 8.8±2.4mg/dL in preterm neonates. Serum prealbumin concentration was significantly correlated with birth weight, gestational age and serum albumin level(P<0.01). In the neonates, prealbumin concentrations on day 3 of life were significantly lower than initial concentrations, and then they rised on the day 7 of life(P< 0.05). Serial serum prealbumin level was significantly correlated with body weight, calory intake and protein intake(P<0.01). When caloric and protein intakes were higher than 100kcal/kg/d and 2g/kg/d, respectively, there were significant differences in the changes of prealbumin concentrations on days 0, 3, and 7 of life, compared with those in neonates with lower intake. Conclusion : Serum prealbumin concentration could be used in the early recognition of changes in nutritional state in neonates.
