연구목적 : 강박증의 동반인격장애에 관한 연구들은 기존의 개념과 달리 강박성 인격장애와 강박증 간에는 특이적인 관계가 없으며, 강박증 환자들은 다양한 인격장애를 동반한다는 결과를 보여주었다. 그러나 이러한 연구들은 동반 인격장애에 관한 기술적인 분석에 그쳤고, 강박증 환자군의 임상 증상과 동반 인격장애 양상간의 연관성에 관한 분석을 시행하지 않았다. 본 연구의 목적은 강박증 환자군에서의 동반 인격장애를 평가하고 강박증 환자의 다양한 증상과 동반 인격특성 간의 연관성에 대해 연구하는 것이다. 방 법 : DSM-IV의 강박증의 진단기준을 만족하는 59명의 환자군과 32명의 정상대조군을 대상으로 인격장애 질문지를 적용한 후 4∼6점의 절단점을 기준으로 인격장애의 진단이 내려졌다. 먼저 환자군과 정상대조군 간의 특정 인격장애 빈도의 차이를 알아보기 위하여 Fisher's exact test를 시행한 후, 두집단 간에 유의한 차이가 있는 것으로 밝혀진 인격장애 척도 점수에 미치는 Y-BOCS,BDI,BAI점수의 영향을 알아보기 위하여 다중선형회귀 분석을 시행하였다. 결 과 : 1) Fisher's exact test 결과 강박증 환자군은 정상 대조군에 비해 경계성 인격장애(18.6%vs 0%, p=0.007). 회피성 인격장애(55.9% vs 18.8%, p=0.001), 우울성 인격장애(40.7% vs 0%, p=0.000)의 비율이 유의하게 높았다. 2) 다중선형회귀분석 결과 Y-BOCS 점수 (t=2.10, p=0.043)와 BAI점수(t=2.60, p=0.014)는 경계성 인격장애 점수에 유의한 영향을 주는 것으로 나타났다. 또한 BAI점수(t=3.23, p<0.003)는 회피성 인격장애 저수에, BDI점수 (t=3.08, p=0.004)는 우울성 인격장애 점수에 유의한 영향을 주는 것으로 나타났다. 결 론 : 강박증 환자군은 정상 대조군에 비해 회피성 인격장애, 우울성 인격장애, 경계성 인격장애의 동반율이 높고, 강박증이 경계성 인격장애의 심각도에 유의한 영향을 미치는 것으로 사료된다. The purpose of this study was to assess the comorbid axis-Ⅱ disorders of obsessive compulsive disorder(OCD) patients and to investigate the relationship between symptoms of OCD and the comorbid personality traits. The subjects were 59 patients who met DSM-IV criteria for obsessive-compulsive disorder and 32 normal controls. All subjects completed personality Disorder Questionnaire-IV(PDQ-IV). The patients completed Beck Depression Inventory(BDI) and Beck Anxiety Inventory(BAI), and were rated with Yale-Brown Obsessive Compulsive Scale(YBOCS). The results were as follows. 1) The OCD patients showed significantly higher prevalence of avoidant, depresssive and borderline personality disorder(p<0.01) compared to controls. 2) The BAI score had significant effect on the avoidant personality score(t=3,23, p<0.003). The BDI score had significant effect on the depressive personality score(t=3.08, p=0.004). The YBOCS(t=2.10, p=0.043) and BAI(t=2.60, p=0.014) scores had significant effects on the borderline personality score. We found that OCD patients had higher prevalence of avoidant, depressive, and borderline personality disorders. We also found that obsessive-compulsive symptoms have significant effect on the severity of borderline personalty traits. We suggest that it would be very helpful to consider Axis-Ⅱ disorders for managing patients with obsessive-compulsive disorder.

Kim Sang-Jun,Yun Ung-Hui,Lee Heon-Gyeong,Kim Jin-Gyu 대한전기학회 2022 Journal of Electrical Engineering & Technology Vol.17 No.2

The kinetic energy transfer of ions in non-uniform electric fi eld causes the fl ow of fl uids called an ionic wind. This study investigates ionic wind velocity by the multi-stage confi guration of corona discharge electrodes and installation of accelerating electrodes. Ionic wind velocity can be improved, independent of the increase in the applied voltage being limited by the breakdown voltage. The amount of ion generation is increased and overlapped by the multi-stage confi guration that considers reverse ionization and the movement distance of ions. This study shows the shape of accelerating electrodes that minimize traps occurred during ion movement. Ultimately, the ionic wind velocity was improved by 142.3% and the energy effi ciency was improved by 5.1 times compared to the single-stage ionic wind generator

Kim, Hyun-Ho,Kim, Do-Hyung,Kim, Jong-Bin,Kim, Hee-Jin,Ahn, Jae-Ung,Kang, In-Soo,Lee, Jun-Kyu,Ahn, Hyo-Sok,Kim, Sung-Dong 한국마이크로전자및패키징학회 2010 마이크로전자 및 패키징학회지 Vol.17 No.3

In this study, we investigated the effects of UBM(Under Bump Metallization) and solder composition on the drop impact reliability of wafer level packaging. Fan-in type WLP chips were prepared with different solder ball composition (Sn3.0Ag0.5Cu, and Sn1.0Ag0.5Cu) and UBM (Cu 10 ${\mu}m$, Cu 5 ${\mu}m$\Ni 3 ${\mu}m$). Drop test was performed up to 200 cycles with 1500G acceleration according to JESD22-B111. Cu\Ni UBM showed better drop performance than Cu UBM, which could be attributed to suppression of IMC formation by Ni diffusion barrier. SAC105 was slightly better than SAC305 in terms of MTTF. Drop failure occurred at board side for Cu UBM and chip side for Cu\Ni UBM, independent of solder composition. Corner and center chip position on the board were found to have the shortest drop lifetime due to stress waves generated from impact.

Kim, Hyung-Ung,Park, Chang-Sik,Jun, Moo-Hyung,Jeong, Seong-Mok,Kim, Myung-Cheol 충남대학교 형질전환복제돼지연구센터 2007 논문집 Vol. No.10

연구의 목적은 고양이에서 zoletil^(?)과 medetomidine 약물 마취 시 atipamezole의 임상적 길항 효과를 보기 위함이다. 마취를 하고 다시 회복 되는 동안에 체온, 심박수, 호흡수를 측정하였다. 이 연구에서는 12 마리의 건강한 한국 잡종 고양이를 사용하였다. 각 6마리씩 무작위로 선별하여 대조군(zoletil^(?)과 medetomidine, ZM)과 실험군(zoletil^(?), medetomidine과 길항제인 atipamezole, ZMA) 두 군으로 나누었다. 모든 고양이들은 투여 전 15분, 주사후 5분, 25분, 105분에 평가하였으며, 길항제인 atipamezole은 마취 주사 후 20분에 근육 주사 하였다. 회복 시간, 심박수, 호흡수는 두 군간 유의성이 있는 결과를 보였고 체온은 유의성을 나타내지 않았다. 두 군 모두 zoletil^(?)과 medetomidine 마취 주사 후 4분 내에 횡와 되는 결과를 보였고 마취 시간도 3시간 가까이 지속해 고양이에 있어서 이들 약물이 좋은 마취 효과가 있음을 보여 주었다. 회복 시 마취 부작용은 거의 보이지 않았다. 고양이가 마취에서 회복되어 기립 자세를 하기까지 걸리는 시간이 ZM 군에서는 210.8±45.6 시간으로 나타났고, ZMA 군에서는 154.2±21.1 시간으로 나타났다. 길항제를 투여한 ZMA 군에서 회복시간이 거의 한 시간 가까이 단축되어 ZMA군이 ZM군보다 회복이 빠르다는 결과를 보였다. 본 연구에서 atipamezole은 medetomidine-tiletamine/zolazepam으로 병용 마취된 고양이에서 유용한 회복효과를 발휘하였다. The purpose of the study is to evaluate the clinical antagonistic effect of atipamezole(0.25 mg/kg,IM) in cats anesthetized with tiletamine-zolazepam (zoletil^(?), 10 mg/kg, IM) and medetomidine (0.05 mg/kg, IM). Twelve healthy 1 year old Korean mixed breed cats were used for this study. They were 4 males and 8 females. These cats were randomly assigned to two groups. One was control group (Zoletil^(?) + medetomidine, ZM), and the other was treatment group (Zoletil^(?)+medetomidine and antagonism by atiparnezole, ZMA). All cats were examined 15 minutes before,5, 25, 65 and 105 minutes after administration of tiletarnine-zolazepam and medetomidine. Atipamezole was injected intramuscularly 20 minutes after ZM administation. Recovery time, heart rate, respiratory rate, total plasma protein and blood glucose were significantly different between ZM group and ZMA group (P < 0.05). However, rectal temperature was not significantly different between ZM group and ZMA group. Two groups were able to induce sternal recumbency within 2 minutes and lateral recumbency within 4 minutes after the anesthetics injection. Mean sternal position time (mean ± SD) was 174.0± 44.6 and 116.2 ± 27.3 minutes, and mean standing position time was 210.8 ± 45.6 and 154.2 ± 21.1 minutes in ZM and ZMA group, respectively. In these two groups, adverse effects during recovery time from anesthesia were not seen. As a result, the ZMA group had a faster recovery than the ZM group. Thus it was concluded that atipamezole could exert a useful reversal effect in cats anesthetized with rnedetornidine-tiletamine/zolazepam combination.

ERCP was performed in 34 cases of obstructive janndice at Busan National University Hospital between June 1981 and October 1982, and those findings were compared with the final surgical operative diagnoses. The results were as follows: 1) The ratio of male to female was about l. 6: 1 and most of them were in the 5th decade to 7th decade. 2) Upper abdominal pain and tenderness were the cardinal symptom and sign. 3) Successful ERCP was obtained in 32 cases among the total of 34 cases(94.1%)Selective success rates by indications were 77.8%(21/27) in suspected biliary lesions and 85.7%(6/7) in suspected panceatic lesions. 4) ERCP diagnoses were biliary stone(11 cases), eholangiocarcinoma(6 cases), pancreatic head ca. (4 cases), Ampulla of Vater ca. (2 cases), normal cholangiogram(2 cases), and normal parcreatogram(2 cases). 5) Eighteen cases out of 24 surgical operative cases were diagnosed by ERCP alone, The diagnostic rates of ERCP by surgical operation in obstructive jaundce was 75%. Complications of ERCP were not clinically significant. It suggests that ERCP is a very useful diagnostic method in the differential diagnosis of obstructive jaundice.

The Superficial Inferior Epigastric Artery Flap and its Relevant Vascular Anatomy in Korean Women

Kim, Byung Jun,Choi, Jun Ho,Kim, Tae Hoon,Jin, Ung Sik,Minn, Kyung Won,Chang, Hak Korean Society of Plastic and Reconstructive Surge 2014 Archives of Plastic Surgery Vol.41 No.6

Background Lower abdominal soft tissue transfer is the standard procedure for breast reconstruction. However, abdominal wall weakness and herniation commonly occur postoperatively at the donor site. To reduce the morbidities of the donor site, the superficial inferior epigastric artery (SIEA) flap was introduced, but inconsistent anatomy of the SIEA has reduced its utility. In the present study, the anatomy of the superficial inferior epigastric vessels in Korean women was determined with regards to breast reconstructive surgery. Methods The vascular anatomies of the SIEA and superficial inferior epigastric vein (SIEV) were evaluated on 32 breast cancer patients receiving free transverse rectus abdominis musculocutaneous flap reconstruction after mastectomy. The existence, pulsation, location, external diameter, and depth of the SIEA and SIEV were measured at the lower abdominal incision level. Results SIEA and SIEV were present in 48/64 (75.00%) and 63/64 (98.44%) hemi-abdomens, respectively. Pulsation of the SIEA was found in 44/48 (91.67%) cases. The mean locations of SIEA and SIEV were +5.79 (${\pm}12.87$) mm, and -8.14 (${\pm}15.24$) mm from the midpoint between the anterior superior iliac spine and symphysis pubis, respectively. The mean external diameters of SIEA and SIEV were 1.20 (${\pm}0.39$) mm and 1.37 (${\pm}0.33$) mm, and they were found at a mean depth of 9.75 (${\pm}2.67$) mm and 8.33 (${\pm}2.65$) mm, respectively. Conclusions The SIEA was absent in 25% of Korean women and had a relatively small caliber. Therefore, careful preoperative assessment of the lower abdominal vasculature is required to achieve successful breast reconstruction using SIEA flaps.

Jun, Jong-Won,Kim, Tae-Wan,Il Hong, Seok,Kim, Joo-Wan,Jhung, Sung Hwa,Kim, Chul-Ung Elsevier 2018 CATALYSIS TODAY - Vol.303 No.-

<P><B>Abstract</B></P> <P>This study is the first to examine the selective production of ethylene from propylene (propylene-to-ethylene, PTE) with using various structural types of zeolites. The catalytic performances of these zeolite catalysts were tested in a continuous fixed-bed reactor system with respect to ethylene selectivity and catalyst stability during the overall reaction period. Among these zeolite catalysts, ten-membered ring zeolites with three-dimensional pore structures (ZSM-5 and ZSM-11) exhibited stable catalytic performances with considerable ethylene selectivity compared to other zeolite catalysts. The ZSM-5 zeolite, thus selected, was further studied in the PTE reaction with different silica-alumina ratios (Si/Al<SUB>2</SUB>, SARs), a surface modification with phosphorus, and under different reaction conditions in order to investigate the effect of acidity, surface properties, and process variables on the catalytic activity as well as to additional improve the ethylene selectivity. From these studies, the PTE reaction was found to depend strongly on the reaction condition, SAR and surface P modification in the ZSM-5 zeolite. The phosphorous-modified ZSM-5 catalyst exhibited the highest ethylene selectivity of more than 70% with moderate propylene conversion of 36.3% at a low propylene space velocity and a low partial pressure condition.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Stable & high selective propylene-to-ethylene (PTE) over zeolites was first reported. </LI> <LI> 10-MR zeolites with 3-D structure showed high catalytic activity for the PTE reaction. </LI> <LI> Catalytic results of P-ZSM-5 were relative to acid sites from Si/Al<SUB>2</SUB> and P loading. </LI> <LI> Propylene partial pressure is one of the key parameters to the ethylene selectivity. </LI> <LI> The maximum ethylene selectivity could be expected around 71–75% over P-ZSM-5. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
