Background: Non-variceal upper GI bleeding (NVUGIB) is a common medical problem that has signifi cant association with morbidity and mortality. Angiographic detection and subsequent transarterial embolization (TAE) is a primary treatment option when medical and endoscopic treatments fail. We investigated clinical factors that could affect the success of the angiographic detection and prognosis after TAE in patients with NVUGIB refractory to endoscopic therapy. Methods: A retrospective analysis of the clinical data was done in patients with failed endoscopic treatment who underwent angiography for the treatment of acute NVUGIB between May 2002 and May 2013. Patients were divided into detection or non-detection groups according to the presence of bleeding stigmata in angiographic fi nding. Rebleeding defi ned as subsequent bleeding event within 7 days and mortality within 30days were analyzed as outcome parameters after TAE following detection in angiography. Results: A total 45 patients 37 (male, mean age, 65.9±14.9 years) were analyzed and classifi ed as a detection group (n=25, 55.5%) and non-detection group (n=20, 44.6%). Peptic ulcers were the most common cause of refractory NVUGIB. Larger transfusion amount (5.7±3.9 unit vs. 3.5±2.8 unit; P=0.03), prolonged aPTT level (34.2±17.3 sec vs. 21.8±13.8 sec; P=0.01) and short time interval between last endoscopy and angiography (17.5±25.9 hours vs. 34.3±59.5 hours; P=0.04) were found to be signifi cant factors for predicting angiographic detection. TAE was performed in all patients detected in angiography. Rebleeding (44%) was significantly associated with higher Rockall score (8.3±1.5 vs. 6.6±2.4; P=0.046) and mortality (12%) was signifi cantly associated with higher Rockall score (9.3±0.6 vs. 7.1±2.2; P=0.002) and higher level of BUN (55.3±47.4 vs. 27.6±17.4; P=0.01). Conclusions: Clinical characteristics associated with angiographic detection in patients with NVUGIB refractory to endoscopic therapy were severe bleeding, bleeding tendency and early angiographic intervention. The Rockall score is useful parameter for predicting rebleeding and mortality after TAE.

영아 급성 출혈성 부종 (acute hemorrhagic edema of infancy, AHEI)은 4개월에서 2세 사시의 소아에서 주로 얼굴과 사지에 국한된 염증성 부종과 특징적인 자반성 피부 병변을 보이는 백혈구 파쇄성 혈관염으로, 내부 장기의 침범 없이 급성의 피부 병변을 보이며 대게 1-3주 내에 자연 치유되는 양성질환이다. 이 질환은 비슷한 임상양상이나 조직소견을 보이는 다양한 질환들과의 감별이 필요한데, 특히 소아에서는 Henoch-Schonlein 자반증과의 감별이 특히 중요하다. 이에 저자들은 자반성 피부병변과 얼굴과 사지의 부종 등의 특징적 피부증상과 피부 병리소견을 통하여 AHEI로 진단한 17개월 남아 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Acute hemorrhagic edema of infancy (AHEI) is a variant of leukocytoclastic vasculitis which is characterized by edema and pupuric skin lesions involving mainly the face and extremities. However, there is usually no visceral involvement. The onset of the disease is acute but self-limited, bearing a benign clinical course within 1 to 3 weeks. The main differential diagnosis of AHEI is Henoch-Schonlein purpura. We report a 17-month old boy with AHEI presenting purpuric skin lesions, edema on face and extremities, and leukocytoclastic vasculitis on skin pathology.

Objectives:Since the order for medical treatment as outpatient has begun in Korea, there have been no requests due to the absence of specific details relating to its enforcement and lack of understanding of related specialists. We reviewed current guidelines and administrative conditions for order for medical treatment as outpatient in Korea, and examined examples of operation and related regulations of developed countries. Methods:Korean studies concerning development of the order for medical treatment as outpatient were inquired. We investigated the guidelines of other countries including U.S.A., Australia, United Kingdom and Canada. The survey of related specialists for the improvement of order for medical treatment as outpatient was performed. Results:Related specialists agreed that current order for medical treatment as outpatient needed more detailed guidelines for candidate patients, processes and management for noncompliance. Additionally, majority of the specialists suggested that candidates for order for medical treatment as outpatient should be extended for not only hospitalized patients but also patients in community. Conclusions:We reviewed detailed considerations regarding candidate recipients within current legislation, complemented post-enforcement report, management procedures, and stipulated actions for noncompliance, to be used as practical guidelines for application. More fundamental measures than complementation of guidelines, such as modification of related legislature will be needed to increase usage, and further details with reference to confidentiality of recipients and safety measures and financial support of treatment personnel will be needed.

Objectives : This study is to investigate the hypothesis that schizophrenic patients have difficulty in inferring mental state of others. Methods : Twenty schizophrenic patients and twenty normal subjects were administered to the Cartoon Task required inferring the character's intention in a given context. Results : The schizophrenic patients showed a statistically significant impairment in the Cartoon Task. Both groups chose the card depicting a frequent everyday action significantly more rather than the similar card to the last picture in each story for wrong answers. Conclusion : These preliminary results suggest that schizophrenia is associated with a specific deficit of the cognitive ability referred to as social cognition, and this deficit can be detected not only in the acute phase as found in previous research studies, but also in remission. Also when subjects fail to appreciate what is going on in the minds of other people, they seem to rely on a socially familiar experience.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Na, Young-Soon,Kim, Seung-Mi,Jung, Kyung-Ah,Yang, Soo-Jin,Hong, Yong Sang,Ryu, Min-Hee,Ro, Seonggu,Cho, Dong-Hyung,Kim, Jin Cheon,Jin, Dong-Hoon,Lee, Jung Shin,Kim, Tae Won Spandidos Publications 2010 ONCOLOGY REPORTS Vol.24 No.6

<P>Chemotherapies for colon cancer have recently advanced. However, there is still a need to develop agents and identify effective regimens for better treatments of colon cancer. Histone deacetylase inhibitors (HDACIs) have shown potential as anti-cancer agents. We investigated the anti-tumor effects of CG2 (an HDACI) in combination with irinotecan, 5-FU, or oxaliplatin. Combinations of CG2 with SN38 (the active form of irinotecan), 5FU, or oxaliplatin were more effective than the agents alone when used to inhibit the growth of HCT116 cells. The protein expressions of acetyl-H3, p21, caspase-3, -8, and -9, PARP, and XIAP were affected in a time- and dose-dependent manner in HCT116 cells treated with the CG2 alone or combined CG2 and SN-38. In HCT116 xenografts, the HDACI CG2 in combination with irinotecan dramatically inhibited tumor growth without showing additive toxicity. These data indicate that CG2 together with irinotecan is a promising combination novel treatment for colon cancer.</P>

Jin Bae Na,Hyoungku Kang,Young Jin Hwang,Seong Eun Yang,Dong Keun Park,Duck Kweon Bae,Tae Kuk Ko IEEE 2010 IEEE transactions on applied superconductivity Vol.20 No.3

<P>The electrical breakdown characteristics of liquid nitrogen should be investigated for developing of a high voltage superconducting machine. This paper deals with the experimental study for the verification of dielectric characteristics of sub-cooled in accordance with utilization factors. AC dielectric experiments were carried out by using sphere-plane electrode systems. The utilization factors of simulated electrode systems were controlled by gap distance between two electrodes and diameter of a sphere electrode. Also, dielectric experiments according to various pressures, 1.25, 1.5 and 2 bar, by gaseous nitrogen were carried out. In this paper, the electrical breakdown criteria of sub-cooled conditions are derived with various sphere diameters. In addition, the sub-cooled condition and saturated condition were compared with AC dielectric characteristics. Research results could be applicable to designing of high voltage superconducting applications such as superconducting fault limiters (SFCLs), cables and large-capacity transformers.</P>

A Study on the Normal Zone Propagation Velocity of the Racetrack Type Coil With Difference Shapes of Coil Bobbin

Jin Bae Na,Young Jin Hwang,Tae Kuk Ko IEEE 2013 IEEE transactions on applied superconductivity Vol.23 No.3

<P>The high-temperature superconductors (HTS) have large stability compared with to temperature superconductors. However, normal zone propagation velocity (NZPV) of HTS should be slowed due to its high stability. To make high stable superconducting magnet with HTS, one of the beneficial methods is to increase the NZPV of superconducting magnet by adjusting the winding strength in the racetrack coil. The racetrack type coil (RC) is widely used to make the superconducting field coil of wind turbine generators. The conventional RC consists of two parts, which are the round section and straight section. Suitable deformation configuration of the straight part can be suggested and calculated by finite element method simulation. The central magnetic field and total magnetic flux were calculated to investigate the deformation effect of RC. Two RCs with GdBCO were fabricated to measure NZPV. One of the RCs was a deformed straight section such as the D-shape. NZPV was compared with each RC. It was found that NZPV of deformation RC was increased to lower internal overheating. Finally, these results can be applied for developing large-scale wind turbine generation.</P>
