홍용신,박은진,김성균,곽재영,허성주,박지만 大韓齒科保存學會 2011 Restorative Dentistry & Endodontics Vol.36 No.6

구강 스캐너와 CAD/CAM 기술로 인해 컴퓨터로 제작하는 방식이 활발히 보급된 고정식 보철 증례와는 달리, 의치를 디지털 방식으로 제작하는 데에는 아직 한계가 많다. 촉각을 느낄 수 있는 입력 장비와 전자 서베잉의 개념, 그리고 쾌속 조형법의 적용으로 인해 국소의치를 디지털로 제작할 수 있는 솔루션이 최근 소개되고 있다. 본 증례보고에서는 이러한 국소의치의 디지털 솔루션을 이용하여 총 다섯 명의 환자에서 서베이드 금관 및 국소의치를 제작하였다. 인상 과정상의 문제로 모형과 실제 치아 사이의 형태적 차이가 있었던 경우를 제외하고는 국소의치의 적합도는 우수했으며, 장착 후 안정성과 착탈 시의 유지력 또한 임상에서 적용하는 데에 문제가 없었다. There are still many limitations on fabricating dentures using digital method while computerized production of fixed prostheses utilizing intraoral scanner and CAD/CAM technology has propagated rapidly. Recently the digital solution of fabricating removable partial denture by applying haptic input device, electronic surveying, and rapid prototyping was introduced. In this case presentation, five patients were treated with surveyed crown and removable partial dentures by this digital solution. Fit of dentures was excellent except for one case which showed morphological difference between the actual teeth and that of master cast by the erroneous impression process. There also was not any problem of stability and retention after adaptation in the clinical setting.

홍용신,박은진,김선종,김명래,허성주,박지만 대한치과보철학회 2012 대한치과보철학회지 Vol.50 No.1

최근 디지털 인상채득 시스템이 개발되면서 이를 기존의 CAD/CAM 시스템과 접목한 인레이, 온레이, 크라운이나 간단한 계속가공의치 등의 고정성 보철물의 제작이 활발히 소개되고 있다. 그러나 임플란트 보철에서는 주로 기존의 아날로그식 인상채득 후 이를 스캔하여 제작하는 방법이 사용되어 왔으나, 구강 내 디지털 스캔한 데이터를 이용하여 나사형 보철물을 제작하는 술식은 아직 활발히 이루어지지 않았다. 이에 본 증례보고에서는 6명의 환자를 대상으로 구강 내 스캐너인 iTero를 사용하여 디지털 스캔을 시행한 후 그중 다섯명은 맞춤형 지대주와 시멘트 합착 후 나사형 임플란트 보철물(screw-retained implant prosthesis after cementation, or SCRP)을 제작하였고, 임상적으로 기능과 심미적인 측면으로 만족할 만한 결과를 얻었기에 이를 보고하고자 한다. Fixed dental prostheses such as inlay, onlay, crown, and bridge fabricated by CAD/CAM technique combined with digital impressions is getting popular due to the recent rapid progress of digital impression taking system. For the scope of implant prosthesis, however, digital intra-oral scan hasn’t been actively utilized for the fabrication of superstructures. In this case report, 6 cases of titanium-milled custom abutment based on the iTero intra-oral scan data were introduced, five of them were restored with screw-type prosthesis after cementation (SCRP) and the clinical results were satisfactory on restoring the function and esthetics.

Effect of Harvesting Season on the β - Cryptoxanthin in Shiranuhi Mandarin Fruit Cultivated in Jeju Island

Ji-Man Heo,Do-Hyun Kim,In-Jung Kim,Sam-Pin Lee,Chan-Shick Kim 한국식품영양과학회 2005 Preventive Nutrition and Food Science Vol.10 No.3

β-Cryptoxanthin content was determined in Shiranuhi mandarin fruits harvested at monthly intervals from October to February in Jeju Island. Crude carotenoids were extracted from both peel and flesh of Shiranuhi mandarin fruits and analyzed using TLC and HPLC; β-cryptoxanthin was indicated the Rf value of 3.2 and retention time of 23 min, respectively. β-Cryptoxanthin contents in both peel and flesh were increased gradually as the citrus fruits ripened fully until harvesting season (February). According to the harvesting time, β-cryptoxanthin contents in the peel were 0.15 mg% (October), 0.28 mg% (November), 0.38 mg% (December), 1.23 mg% (January), and 1.71 mg% (February). In the flesh, β-cryptoxanthin contents were lower than those of peels, having 0.06 mg% (October), 0.08 mg% (November), 0.19 mg% (December), 0.26 mg% (January), and 0.65 mg% (February). These results demonstrate that β-cryptoxanthin in Shiranuhi mandarin fruits accumulated during ripening of the citrus fruits. In particular, the peels had much higher concentrations of β-cryptoxanthin and have potential for use as a functional ingredient.

Bud germination rates of four gamma ray-irradiated Citrus species

Ji-Man Heo,In-Jung Kim 한국육종학회 2014 한국육종학회 심포지엄 Vol.2014 No.07

we analyzed the survival rate through the measurement of germinability of the gamma-ray irradiated buds of 4 Citrus species, C. hybrid ‘Kiomi’, C. hybrid ‘Setoka’, C. hybrid ‘Kanpei’, and C. junos, in greenhouse. To induce mutation, spring buds of Citrus with 0, 10, 20, 40, 60, 80 and 100 Gy of gamma radiation were irradiated and then were vgrafted onto trifoliate orange rootstock. The rootstock number per gamma ray dosage was two hundreds. After after 6 months growth, the shoot germination rate from gamma ray-irradiated buds presented lower viability than those of non-irradiated buds. Higher dossage of irradiation more inhibited bud germination at all experimental groups of citrus. The viability of unirradiated citrus plants was C. junos > ‘Setoka’ > ‘Kiomi’ > ‘Kanpei’. We have determined LD50 of gamma ray-irradiation.

Objective Appropriate gestational weight gain (GWG) is important in diabetic women. Current GWG guideline is for US general population, but not specific for diabetic women. We compared the effect of GWG on perinatal outcomes between diabetic and non-diabetic women. Methods Fifty two hundred and twelve women who delivered live singleton infants at Korea University Medical Center from January 2009 to December 2013 were included. One hundred twenty-nine overt diabetes women and 322 gestational diabetes women were categorized as diabetic women, and the others were categorized as none-diabetic women. 5,212 women were categorized by GWG (low 1,081; adequate 2,102; or high 2,029; according to the 2009 Institute of Medicine guidelines), and each of the 3 GWG groups was categorized into 2 groups; diabetic or non-diabetic women. And then, we compared perinatal outcomes between diabetic and non-diabetic groups. Results In each 3 GWG groups, primary cesarean section delivery, high birth weight, and large for gestational age rates were significantly higher in diabetic women than non-diabetic women. Only in adequate GWG group, preterm birth rate was significantly higher in diabetic women than non-diabetic women. Conclusion Our study shows that diabetic women had higher rates of adverse perinatal outcomes than non-diabetic women, although they achieved same GWG. It suggests that current GWG guideline may not be adequate for diabetic women, and that diabetic women may need more strict GWG control than normal population.

( Ji Man Heo ),( Hye Jin Jeon ),( Ji Youn Kim ),( Myeong Hi Hahn ),( Hai Joong Kim ) 대한산부인과학회 2012 대한산부인과학회 학술대회 Vol.99 No.-

Cystic hygroma (CH) is a congenital malformation of the lymphatic system characterized by single or multiple cystic masses that are mostly located around the neck. The prognosis depends upon the time of detection, associated chromosomal anomaly, and size of the mass. We present a case report of the CH that was detected at 25 week`s gestation on second-trimester sonography. A 31-year-old primigravida was referred to our hospital at 25 weeks plus 2 days` gestation for a fetal neck mass. 2D USG showed 3.0 cm × 2.0 cm sized CH located anterolaterally on left side of fetal neck. No other congenital anomaly was seen sonographically. During serial flow up, the size of the CH was increased to 4.9 cm ⅹ 3.9 cm at 37 weeks plus 4 days` gestation. At 39 weeks plus 1 day gestation, the patient was admitted due to rupture of membranes, and spontaneous labor began. However, an emergency cesarean section was performed due to non reassuring fetal heart rate, at 39 weeks plus 2 day gestation. The baby was male, and his weight was 2968g. The Apgar scores were 7/8. The baby was admitted to the neonatal intensive care unit. Postnatal neck USG and MRI scan showed 6 × 6.3 × 5.8 cm, huge cystic mass in the left submandibular space extending to masseter and parapharyngeal spaces. In addition, airway was deviated to the right, from oropharynx to subglottic level. After two treatments of sclerotherapy, the size of the CH was decreased, and only some residual fluid collection was remained. The baby was discharge 29 days after admission without serious complications and other congenital anomalies

Heo, Ji Hoe,Kim, Young Dae,Nam, Hyo Suk,Hong, Keun-sik,Ahn, Seong Hwan,Cho, Hyun Ji,Choi, Hye-Yeon,Han, Sang Won,Cha, Myoung-Jin,Hong, Ji Man,Kim, Gyeong-Moon,Kim, Gyu Sik,Kim, Hye Jin,Kim, Seo Hyun,K Ovid Technologies Wolters Kluwer -American Heart A 2010 Stroke Vol.41 No.9

<P>Background and Purpose-An effective stroke code system that can expedite rapid thrombolytic treatment requires effective notification/communication and an organized team approach. We developed a stroke code program based on the computerized physician order entry (CPOE) system and investigated whether implementation of this CPOE-based program is useful for reducing the time from arrival at emergency departments (ED) to evaluation steps and the initiation of thrombolytic treatment in various hospital settings. Methods-The CPOE-based program was implemented by 10 hospitals. Time intervals from arrival at the ED to blood tests, computed tomography scanning, and thrombolytic treatment during the 1-year period before and the 1-year period after the program implementation were compared. Results-Time intervals from ED arrival to evaluation steps were significantly reduced after implementation of the CPOE-based program. Times from ED arrival to CT scan, complete blood counts, and prothrombin time testing were reduced by 7.7 minutes, 5.6 minutes, and 26.8 minutes, respectively (P<0.001). The time from ED arrival to intravenous thrombolysis was reduced from 71.7 +/- 33.6 minutes to 56.6 +/- 26.9 minutes (P<0.001). The number of patients who were treated with thrombolysis increased from 3.4% (199/5798 patients) before the CPOE-based program to 5.8% (312/5405 patients) afterward (P<0.001). The CPOE implementation also improved the inverse relationship between onset-to-door time and door-to-needle time. Conclusions-The CPOE-based stroke code could be successfully implemented to reduce in-hospital time delay in thrombolytic therapy in various hospital settings. CPOE may be used as an efficient tool to facilitate in-hospital notification/communication and an organized team approach. (Stroke. 2010; 41:1978-1983.)</P>

( Ji Man Heo ),( Min Ji Choo ),( Hye Sook Im ),( Geum Joon Cho ),( Soon Cheol Hong ),( Min Jeong Oh ),( Hai Joong Kim ) 대한산부인과학회 2012 대한산부인과학회 학술대회 Vol.99 No.-

The aim of this study was to investigate the impact of excessive gestational weight gain (GWG) and insulin therapy on perinatal outcomes in women with gestational (GDM) and pregestational diabetes mellitus (DM). A study was conducted among 92 GDM, 45 DM women who delivered a live singleton infant at korea university ansan hospital, Korea, from January 2010 to January 2013. 137 women was categorized by GWG (inadequate, adequate, or excessive, according to the 2009 Institute of Medicine guidelines), by pregestational BMI (underweight, normal weight, overweight, or obese), and by insulin use. Perinatal outcomes were compared among those groups. There was a weak positive correlation between GWG and fetal birthweight (p<0.001, r=0.379). Excessive GWG associated with an increased rate of high birthweight (>4000g, p=0.006), and inadequate GWG associated with an increased rate of low birthweight (<2500g, p<0.001), Preterm birth (birth before 37 weeks` gestation, p=0.004), and neonatal intensive care unit (NICU) admission (p=0.007). There was a weak positive correlation between pregestational BMI and birthweight (p=0.04, r=0.176), but birthweight was no significantly difference among those 4 BMI groups. perinatal outcomes are not significantly different among the BMI groups. Insulin use associated with decreased rate of LBW, Preterm birth, and NICU admission (odds ratio=3.68, 3.99, and 3.08, respectively). Our study shows that GWG is more associated with adverse perinatal outcomes than pregestational BMI, and that insulin use associated with decreased rate of adverse perinatal outcomes in GDM and DM women. These results suggest that adequate weight control is important in GDM and DM women.
