본 연구는 밤나무 교잡종 과실의 조합별 및 개체별 질적특성을 조사함으로써 신품종 육성의 기초 자료뿐만 아니라 품종검정 기준설정의 기초자료로 활용하는데 그 목적이 있다. 과실모양은 11 조합의 많은 개체에서 타원형(85.30%)을 나타냈으며 K×R 등 5조합에서 삼각형(3.78%), R×K 등 8조합에서 원형(5.46%), R×O 등 3조합에서 장타원형(5.46%)으로 각각 관찰되었다. 과피색은 모든 조합에서 암갈색과 적갈색이 각각 49.16%와 38.24%로 관찰되었으며 과피털은 K×R과 R×K만이 과피 전체에서 각각 1개체씩 관찰되었다. 과피털의 밀도는 대부분의 조합에서 92.86%가 중 이상이었으며 좌면의 크기는 E×O, E×R, K×O에서만 중 이상인 것으로 조사되었다. 과실의 광택은 K×O조합에서만 약인 개체가 출현하였으며 열과형태는 모든 조합에서 3가지 형태중 2가지 이상의 형태가 각각 혼재되어 있었다. 양적형질이 우수한 8개체 중 RO-22, RO-25 등 2개체만이 과실모양과 과피색이 각각 장타원형과 암갈색을 나타내었으며 OK-2 제외한 나머지 5개체는 각각 타원형과 적갈색으로 관찰되었다. 과피털의 위치는 OK-2 제외한 모든 개체는 과정부였으며 과피털의 밀도는 IO-15 제외한 모든 개체에서 밀하게 분포하였다. 좌면의 크기는 JO-7과 RO-25 개체가 가장 작았으며 광택은 K×O의 1개체를 제외한 모든 개체에서 중 이상으로 우수하였다. 열과형태는 JO-7과 JO-12, IO-15, OK-15 개체에서 각각 과정부 열과와 주두부 열과 등 각각 단일 형태를 나타낸 반면, OK-2 등 4개체는 과정부 열과와 측면부 열과가 혼재하고 있음을 알 수 있었다. 내피박피성을 조사한 결과, OK-2, OK- 4, OK-15 등 3개체는 내피박피율이 20% 내외로 불량한 반면 RO-25, JO-12 등 2개체의 내피박 피율이 각각 78.6%, 72.4%로 매우 우수한 것으로 나타났다. This study was aimed to applicate as the basic data for the presentation of International Union for the Protection of New Varieties of Plants (UPOV) guideline and for breeding new cultivars through qualitative characteristics of nut in chestnut hybrids. In nut shape, oval type, 85.30%, could be observed in all combinations, and triangle type, 3.78%, in K×R, K×O, E×R, I×R, J×O, and oblong type, 5.46%, in R×O, I×O, E×O, I×R, respectively. Both dark and reddish brown, 49.16% and 38.24%, in nut color were observed in all combinations, and nut pericarp hairs in only K×R, R×K could be observed in whole part. The density of its hair showed above middle rank (92.86%) in most of combinations, and the size of hilum area showed above middle rank in only E×O, K×O and E×R. Ten combinations except K×O showed a good condition in nut luster, and two or three types of three split type could be observed in all combinations, simultaneously. Superior individuals, RO-22 and RO-25, showed oblong and dark brown, but others except OK-2 showed oval and reddish brown in nut shape and nut color, respectively. In position of nut pericarp hair, only OK-2 showed stigma part, but all of superior individuals except IO-15 showed thickness in its density. Only JO-7 and RO-25 were smaller than others in size of hilum area, and JO-7, OK-4, OK-15, RO-22 and RO-25 had nuts with excellent luster. Most of individuals had nuts with two or three types in type of nut split, and JO-7, JO-12, IO-15 and OK-15 showed only single type. In peeling rate, OK-2, OK-4 and OK-15 showed around 20% while RO-25 and JO-12 showed 78.6% and 72.4% being considered as superior individuals for roasted chestnuts.

연구목적: 본 연구는 공동의존성에 영향을 미치는 아동기 가정내 스트레스 요인과 공동의존성과 다른 병리와의 연관성을 규명하고자 하였다. 더불어 특정한 질환에서의 공동의존성의 평가가 가지는 의의를 탐색해 보고자 하였다. 방 법: 연구 대상은 정상 일반인 남성집단 88명과 알코올리즘 남성 집단 76명으로 구성되어 있다. 평가도구는 본 저자가 직접 작성한 '아동기 가정내 스트레스 요인 측정용 설문'과 공동의존 척도(RPS), 간이증상 진단검사(SCL-90-R)를 사용하였다. 통계적 분석은 Mann-Whitmey test, Kruskall- Wallis test, Multiple linear regression analysis, Spearman correlation analysis를 이용하였다. 결 과: 1) 정상 일반인 군과 알코올리즘 군의 공동의존성 평균값은 각각 49.12점(표준편차=15.41)과 88.31점(표준편차=17.48)이었다. 2) 정상 일반인 군에서는 '아동기 부모 사별'(p<0.01) '부모의 알코올리즘'(p<0.01) '부모의 상습적 구타'(p<0.01)의 3가지 요인에서, 알코올리즘 군에서는 '어린시절 부모 사별'(p<0.01) '부모의 알코올리즘'(p<0.01) '부모의 상습적 구타'(p<0.01) '부도의 도박'(p<0.01) '사회 병질자 부모의 존재'(p<0.05)의 5가지 요인에서 스트레스 유무에 따라 공동의존성에 유의한 차이를 보였다. 3) 두 집단 동시에 SCR-90-R의 8개 소척도 중 '대인관계 예민성'이 공동의존성과 가장 높은 연관성(rs>0.06, p<0.01)을 보였다. 이외에도 '우울증' '불안증'등이 두 집단 모두에서 통계적으로 유의한 연관성을 보였다. 결 론: 본 연구는 부모의 알코올리즘뿐만 아니라 여러 가정 내 스트레스 요인이 공동의존성의 발생에 영향을 미칠 수 있음과 공동의존성이 높은 집단이 다른 정신과 질환을 동반할 가능성이 높음을 증명한다고 할 수 있다. Objectives : The aim of this study was to examine the relationships of codependency with family stressors in childhood and psychopathology. Methods : Subjects were a group of 88 normal adult males and a group of 76 alcoholic males. The degree of codependency was assessed with the Korean version of Recovery Potential Survey(RPS). All subjects filled out questionnaires regarding demographic information and family stressors. The psychopathology was measured by self-administred questionnaires using Symptom Check List-90-Revision(SCL-90-R). Results : 1) There were no significant differences in codependency levels by sociodemographic characteristics in two groups, but obvious difference in mean of codependency scores(normal group : 49.12±15.41, alcoholism group : 88.31±17.48). 2) There were significant differences in codependency levels between the presence and absence of parental physical abuse, parental death, and parental alcoholism(p<0.01) in both groups. 3) Among family stressors, parental physical abuse had the largest contribution to codependency level in multiple linear regression. 4) There were significant correlations between the codependency levels and the scores of SCL-90-R's subscales of interpersonal sensitivity, depression, and anxiety in both groups. Conclusion : The codependency levels were related to some family stressors such as parental physical abuse, parental death, and parental alcoholism and the high-level codependency was correlated with higher level of psychopathology in both normal and alcoholism group. These results suggested that various family stressors, as well as parental alcoholism may be predictors of codependency, and codependency also may be a predictor of other psychiatric disorders.

Fabrication of Highly Conductive and Transparent Thin Films from Single-Walled Carbon Nanotubes Using a New Non-ionic Surfactant <i>via</i> Spin Coating

Jo, Jea Woong,Jung, Jae Woong,Lee, Jea Uk,Jo, Won Ho American Chemical Society 2010 ACS NANO Vol.4 No.9

<P>Oligothiophene-terminated poly(ethylene glycol) was synthesized and used as a non-ionic and amphiphilic surfactant for fabricating high-quality single-walled carbon nanotube (SWCNT) films by a simple spin coating method. The absence of charge repulsion between SWCNT/surfactant complexes successfully leads to formation of a dense network of SWCNTs on the substrate through a single deposition of spin coating. When the SWCNT film was treated with nitric acid and thionyl chloride after washed with dichloromethane and water, a high-performance SWCNT film with the sheet resistance of 59 ohm/sq and the transparency of 71% at 550 nm was successfully obtained. Since the SWCNT film exhibits a high value of σ<SUB>dc</SUB>/σ<SUB>ac</SUB> (∼17) and excellent dimensional stability after releasing from the substrate, the film can be used as a transparent electrode in flexible optoelectronic devices.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/ancac3/2010/ancac3.2010.4.issue-9/nn1009837/production/images/medium/nn-2010-009837_0007.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nn1009837'>ACS Electronic Supporting Info</A></P>

A case of extra-adrenal malignant pheochromocytoma with lung, bone and liver metastasis simulating hepatoma or focal nodular hyperplasia in liver

( Uk Jo ),( Hyun Soo Kim ),( Yong Duck Cho ),( Young Woon Chang ) 대한내과학회 2011 대한내과학회 추계학술대회 Vol.2011 No.1

A 51-year old female was referred to our hospital for the evaluation of huge hepatic mass on routine abdominal sonogram. She was also presenting uncontrolled hypertension. An enhanced abdominal CT and liver MRI showed a 94mm sized large hepatic mass favoring hepatoma or focal nodular hyperplasia and metastatic lesion in right iliac bone. On liver biopsy, histology and immunohistochemistry revealed an extra-adrenal malignant pheochromocytoma. On chest CT, which was performed to identify another metastatic lesion, we could find two metastatic nodules on left lower lung. In fact, She had a history of an extra-adrenal pheochromocytoma in retroperitoneum, which had been completely removed surgically about 6 years ago. Unfortunately, after liver biopsy, she underwent disastrous post-biopsy bleeding and hypovolemic shock. We performed arterial embolization to control hemorrhage and it succeeded. Finally, she was diagnosed with a malignant extra-adrenal pheochromocytoma which was primarily originated in retroperitoneum and developed multiple metastases after several years. An extra-adrenal malignant pheochromocytoma is an exrtremely rare disease and, to the best of our knowledge, this is the first reported case of extra-adrenal pheochromocytoma with liver, lung and bone metastasis in Korea. This case suggest that when a huge hepatic mass resembling nodular hyperplasia is discovered, an extra-adrenal pheochromocytoma shuld be included in differential diagnosis.

Methylation of AKAP12{alpha} Promoter in Lung Cancer.

Jo, Uk Hyun,Whang, Young Mi,Sung, Jae Sook,Kim, Yeul Hong Potamitis Press 2010 Anticancer research Vol.30 No.11

<P>AKAP12관 plays an important role in tumour growth suppression by inducing apoptosis. This study investigated whether the promoter methylation of AKAP12관 is associated with lung cancer. AKAP12관 was down-regulated in lung cancer cells and the reduced protein expression was restored by DNA methyl-transferase inhibitor. AKAP12관 promoter was more frequently methylated in tumours than in normal tissues. Furthermore, AKAP12관 methylation was found more frequently in the cells of non-relapse patients after surgery than in those of early relapse patients. In conclusion, this study demonstrated that AKAP12관 expression is regulated by DNA methylation and that AKAP12관 promoter methylation is associated with lung cancer prognosis.</P>

Uncomplicated Superior Vena Cava Perforation during Pacing Lead Insertion

( Uk Jo ),( Hyun Soo Kim ),( Chang Bum Park ),( Hui Jeong Hwang ),( Eun Sun Jin ) 대한내과학회 2011 대한내과학회 추계학술대회 Vol.2011 No.1

Background: Permanent pacemaker implantation can cause serious complication like vascular perforation during lead insertion procedure. Perforation of the great vessels can cause pericardial effusion and cardiac tamponade and it is usually known to be caused by a screw type active-fixation lead. We present a unique case of great vessel perforation by a tined passive-fixation lead during transvenous pacemaker lead implantation. Case report: A 82-year-old female presenting dizziness was admitted to our hospital with a diagnosis of complete AV block. We performed permanent pacemaker implantation. During a tined atrial lead positioning, the lead was extended outside the SVC wall for a while, with no known-cause. We thought that the lead was introduced inside the minor branch of SVC. However, CT scan which was performed after successful pacemaker implantation, revealed that the tined lead penetrated the SVC wall and it caused focal hematoma in mediastinum. The patient`s condition was good throughout the whole procedure and discharged home without any complication on the 7th hospital day. On follow-up CT scan, decrease in focal hematoma was noted. Although it has been known that only a screw type active-fixation lead cause vascular perforation, we experienced SVC perforation by a tined passive-fixation lead which has blunt end. Thus, we suggests that special concern is also needed when a tined lead is inserted. We report this case because, to the best of our knowledge, it is the first report of great vessel perforation by a tined pacing lead.

A case of takotsubo cardiomyopathy caused by severe hyponatremia with underlying coronary artery-left ventricular fistulae

( Uk Jo ),( Hyun Su Kim ),( Byung Hyun Joe ),( Hui Jeong Hwang ),( Chang Bum Park ),( Eun Sun Jin ),( Il Suk Sohn ) 대한내과학회 2011 대한내과학회 추계학술대회 Vol.2011 No.1

Background: Takotsubo cardiomyopathy is characterized by transient LV wall motion abnormality without coronary artery disease. It can be triggered by medical illness. Meanwhile, coronary fistulae are anomalous connection between coronary arteries and cardiac chambers or other vessels and are known to be generally asymptomatic, but rarely manifested by myocardial ischemia due to coronary steal syndrome. We report a unique case of takotsubo cardiomyopathy due to severe hyponatremia with coronary-LV fistulae. Case report: A 65-year-old female was referred to our hospital with the impression of AMI. Severe hyponatremia and elevated troponin-I with ST elevation on ECG was noted. Coronary angiography revealed multiple coronary fistulae originating from the diagonal branch of LAD and draining into LV cavity without any other coronary lesion. Echocardiography showed multiple linear flow signals from epicardium to endocardium at apical lateral wall, suggesting multiple coronary-LV fistulae. Her condition was recovered after conservative management. The follow-up echocardiography showed normal LV wall motion and systolic function. Doppler echocardiography revealed the decreased CFR in both coronary artery and fistula. Those suggest that the myocardium is susceptible to ischemia due to decrease in CFR, which may be associated with coronary fistula. Though we cannot conclude that coronary fistula contribute to the development of takotsubo cardiomyopathy, to the best of our knowledge, this is the first case of takotsubo cardiomyopathy with coronary-LV fistula.
