Eight monitoring stations in the Yeosu National Industrial Complex will determine the concentration of air pollutants measured every hour in 2019, analyze what factors affect them, and how they correlate with the air pollutant measurements. Six air pollutants (SO2, NO2, O3, CO, PM-10 and PM-2.5) measured at eight monitoring stations around Yeosu National Industrial Complex (Seogang-dong, Wolnae-dong, Munsu-dong, Yeocheon-dong, Deokchung-dong, Hwayang-myeon, Yulchon-myeon, Samil-dong) the measurement data for each hour of the year were downloaded to analyze the concentration by weather condition, time zone, season, separation distance from Yeosu Industrial Complex, and separation distance from Gwangyang Industrial Complex. SO2, NO2, and CO concentrations were significantly higher in winter, significantly lower in summer, and O3, PM-10, and PM-2.5 concentrations were significantly higher in spring. SO2, CO, PM-10, and PM-2.5 concentrations were significantly higher between 10 a.m. and 12 p.m., NO2 concentrations were significantly higher between 7 a.m. and 9 a.m., and O3 concentrations were significantly higher between 13 p.m. and 15 p.m.(p<0.001). The concentration of air pollutants (SO2, NO2, CO, PM-10, PM-2.5) excluding O3 was found to have a negative (-) correlation with weather condition, and in the case of O3, it was found to have a positive (+) correlation with PM-10, PM-2.5, temperature and wind speed. It was confirmed that the concentration of air pollutants emitted from the Yeosu National Industrial Complex differs depending on the season, time and distance to the industrial complex. This study aims to establish measures to minimize health damage to residents living relatively close to the industrial complex and contribute to the establishment of management and response measures according to the properties of substances to reduce the concentration of air pollutants in the future.

김철권,조현기,장정희,강동호,조진석,김명정,변원탄 大韓神經精神醫學會 1998 신경정신의학 Vol.37 No.1

본 연구의 목적은 정신분열병 환자의 자녀들과 알코올 의존증 환자의 자녀, 그리고 정신과학적으로 건강한 부모의 자녀들을 대상으로 연속 작업수행력 검사를 이용한 정보처리 과정에서의 지속적 주의력에 관한 사항과 정보 감지능력 검사를 이용한 정보 처리과정에서의 감각등록에 관한 사항을 측정하고 세 군간에 그 결과를 서로 비교하여 차이 유무를 검증하기 위함이다. 연구 대상은 정신분열병 환자의 자녀 28명을 대상군으로 그리고 알코올 의존증 환자의 자녀 18명과 정신과학적으로 건강한 부모를 둔 중고등학생 41명을 대조군으로 하였다. 연구 방법은 대상군 및 두 대조군 모두에게 연속 작업수행력 검사와 정보 감지능력 검사를 순차적으로 시행한 후 그 결과를 서로 비교하였다. 그 결과는 다음과 같다. 1) 연속 작업수행력 검사에서는 대상군이 두 대조군에 비해 맞춘 횟수와 비율이 유의하게 낮았고 놓친 횟수는 반대로 유의하게 높았다. 가장 중요한 변인인 민감도는 대상군이 두 대조군에 비해 유의하게 낮았다. 2) 연속 작업수행력 검사에서 시간 경과에 따른 각 변인의 변화를 보면 맞춘 횟수와 비율에서 대상군이 두 대조군에 비해 시간이 경과할수록 유의하게 감소하였다. 민감도 역시 시간이 경과할수록 대상군이 두 대조군에 비해 유의하게 감소하였다. 3) 연속 작업수행력 검사의 민감도, 정보 감지능력 검사에서의 정답반응 횟수에서 정상 대조군의 분포 곡선중 하위 10% 수치를 절단점으로 잡아 그 수치 이하를 보이는 대상 숫자를 비교해 보면 연속 작업수행력 검사에서만 정신분열병 환자의 자녀군과 정상 대조군 사이에 유의한 차이를 보였다. 4) 대상군, 정상 대조군, 대상군중 연속 작업수행력 검사의 민감도가 하위 10% 이하에 속하는 군의 MMPI를 서로 비교한 결과 세 군간에 MMPI의 모든 변인에서 유의한 차이를 발견할 수 없었다. 5) 정보 감지능력 검사에서는 대상군이 두 대조군에 비해 정답반응과 오답반응을 보이기까지 걸린 평균 시간이 유의하게 길었다. 이상의 연구결과를 통해 저자들은 정신분열병의 발병 위험성이 높은 정신분열병 환자의 자녀군이 알코올 의존증 환자의 자녀군이나 정신과학적으로 건강한 부모를 둔 대조군보다 지속적 주의력에서 결손이 있음을 발견하였고 나아가 이와 같은 지속적 주의력에서의 결손이 정신분열병의 한 가능한 취약지표가 될 수 있을 것으로 사료된다. In order to study the possible vulnerability in the markers of schizophrenia, offsprings of the schizophrenic parents(n=28), offsprings of the alcohol dependent parents(n=18), and offsprings of the psychiatrically normal persons(n=41) were examined for their sustained attention and sensory register by means of Continuous performance test(CPT) and Span apprehension task(SPAN) respectively. The results were as follows : 1) The offsprings of the schizophrenic parents showed a significant deficit in the sustained attention as manifested in the data of CPT by significantly lower hit rate and sensitivity, compared with the offsprings of the alcohol dependent parents and those of the psychiatrically normal persons. No difference was evident in the false alarm rate and response bias among three groups. There was no difference in all variables of the CPT between the offsprings of the alcohol dependent parents and those of the psychiatrically normal persons. 2) The deficit in the sustained attention as revealed by lower hit rate and sensitivity was not apparent in the first part of the CPT. However it emerged and aggravated itself as the test continued in the offsprings of the schizophrenic parents only. 3) Proportion of subjects falling in the extreme low sensitivity of lower 10% of the normal controls was significantly higher in the offsprings of the schizophrenic parent group as compared with the offsprings of the alcohol dependent parents and those of the psychiatrically normal persons with a rate of 29%, 17%, and 10% respectively. 4) No significant difference was noted in all variables of MMPI among normal controls, index group, and the extreme low CPT sensitivity subgroup of index group. 5) The offsprings of the schizophrenic parents showed a significantly delayed response in the time to correct and incorrect response in SPAN compared to the offsprings of the alcohol dependent parents and those of the psychiatrically normal persons. No difference was evident in the number of correct response, number of incorrect response, and number of no response among three groups. There was no difference in all variables of the SPAN between the offsprings of the alcohol dependent parents and those of the psychiatrically normal persons. These results suggest that a subgroup of the offsprings of schizophrenic parents may suffer from the deficit in the sustained attention which may be a vulnerability marker of schizophrenia.

W as a BIT Line Interconnection in COB Structured DRAM and Feasible Diffusion Barrier Layer

Byun, Jeong-Soo,Kim, Jun-Ki,Park, Jin-Won,Kim, Jae-Jeong 한국재료학회 1995 Fabrication and Characterization of Advanced Mater Vol.2 No.e2

Formation of TiN/$TiSi_2$ bilayer from TiX and its utilization as a diffusion barrier for the W bit-line process in capacitor on bit-line (COB) structured dynamic random access memory (DRAM) device have been discussed in this paper. Since the thickness of $TiSi_2$ formed on Si substrate is very thin and uniform, the $TiN_{X}$ contacted $n^{-}$ and $n^{+}$ junction revealed good lectrical properties. The compact structure of the overlying TiN without any grain boundary voiding enabled the $TiN_X$ to be used as a diffusion barier for the W process.

SUPINE POSITION ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY IN A PATIENT WITH SITUS AMBIGUOUS WITH POLYSPLENIA

Byun, Jeong Rae,Jahng, Jae Hoon,Song, Jae Chun,Yu, Jeong Sik,Lee, Dong Ki Blackwell Publishing Asia 2010 Digestive endoscopy Vol.22 No.4

<P>A 58-year-old woman complained of painless jaundice. The serology showed total bilirubin 10.6 mg/dL with direct bilirubin of 7.0 mg/dL. Abdominal computed tomography (CT) scan disclosed an abnormal arrangement of the abdominal viscera and dilation of the biliary tree. A nearly 1.4 cm-sized periampullary mass was seen. These findings are compatible with situs ambiguous with polysplenia and were suggestive of a periampullary tumor. Due to her unusual anatomical features, the patient underwent an endoscopic retrograde cholangiopancreatography (ERCP) in the supine position instead of in the conventional prone position. ERCP showed that the common bile duct (CBD) diameter was increased to 20 mm. Microscopic findings of the biopsy specimen of papillary mass were compatible with an adenocarcinoma of the ampulla of Vater. The clinical stage was stage IA (T1N0M0). Eight days later, a papillectomy was carried out by endoscopic snare resection. Six months later, follow-up studies, including ERCP, abdominal CT and 18-fluorodeoxyglucose positron emission tomography (<SUP>18</SUP>-FDG PET)-CT scan, showed no evidence of recurrence. Although the success rate of supine position ERCP may be influenced by the extent of the intestinal malrotation and the position of the duodenum, we conclude that supine position ERCP can be carried out effectively in a patient with situs anomaly.</P>

Multifocal kaposiform hemangioendothelioma: a rare cause of isolated massive fetal ascites

( Eun Jeong Jeong ),( Jung Mi Byun ),( Dae Hoon Jeong ),( Kyung Bok Lee ),( Moon Su Sung ),( Ki Tae Kim ),( Hyo Jung Ahn ),( Mi Seon Kang ),( Young Nam Kim ) 대한산부인과학회 2016 대한산부인과학회 학술대회 Vol.102 No.-

Kaposiform hemangioendothelioma (KHE) is a locally aggressive vascular tumor that occurs usually in soft tissues of the extremity and rarely in the retroperitoneum. We report a case of isolated massive fetal ascites, which was finally diagnosed as KHE, involving the retroperitoneum and multiple visceral organs with Kasabach-Merritt phenomenon. A 32-year-old woman was referred to our fetal-maternal division at 24 weeks’ gestation due to fetal ascites. During ultrasonographic examination, we observed a single fetus with massive ascites without any other signs of abnormalities or hydrops. Fetal ascites was aggravated on subsequent ultrasound examination at 26 weeks’ gestation, and we performed paracentesis of fetal ascites. Fetal ascites was rapidly reaccumulated at 1-week follow-up after paracentesis. As the fetus developed polyhydramnios, labor was induced at 35 weeks’ gestation, and a male neonate weighing 2840 g was delivered vaginally. The neonatal ascites was diagnosed as chylous ascites and neonatal CT revealed an irregularly contoured retroperitoneal mass with calcification, 35 mm in diameter. On day 73, emergency exploratory laparotomy was performed for suspected intra-abdominal bleeding complicated with severe thrombocytopenia and coagulopathy. During the operation, dark purpuric plaques with ill-defined margin were found in the retroperitoneum, extending to the mesentery, rectosigmoid colon, and left kidney. Hartmann’s rectosigmoidectomy, wedge resection of the kidney, and loop ileostomy were performed. This resection specimen was sent for histological examination and confirmed as KHE. We suspected retroperitoneal KHE might be cause the massive fetal ascites and chylous ascites because it has a high potential to invade the lymphatic vessels aggressively in the retroperitoneal space, which possibly permits intestinal lymph leakage into the pertitoneal cavities.

Antenatal magnesium sulfate for both short-term tocolysis and fetal neuroprotection in premature rupture of the membranes remote from term

( Eun Jeong Jeong ),( Yong Hee Park ),( Moon Hyeong Cho ),( Jung Mi Byun ),( Young Nam Kim ),( Kyung Bok Lee ),( Moon Su Sung ),( Ki Tae Kim ),( Jong Beom Shin ),( Dae Hoon Jeong ) 대한산부인과학회 2016 대한산부인과학회 학술대회 Vol.102 No.-

목적: We aimed to assess whether antenatal magnesium sulfate (MgSO4) therapy given to women with premature rupture of membranes (PROM) remote from term could prolong pregnancy and improve maternal outcomes, perinatal outcomes, and neurodevelopmental outcomes. 방법: We included 184 singleton pregnancies with PROM remote from term (23-31 weeks) between 2005 and 2013. These women were divided into two groups: one group that received MgSO4 therapy for tocolysis (MgSO4 group) and the second group that received no tocolytic therapy (No MgSO4 group). 결과: The latency period was significantly longer in the MgSO4 group (p=0.0017). Antenatal MgSO4 therapy was significantly associated with decreased stillbirth (p=0.0012) and perinatal mortality (p=0.0375). In the subgroup analysis by gestational age at diagnosis of PROM, the subgroup of PROM at 23-27 weeks’ gestation showed significantly reduced the risk of intraventricular hemorrhage (IVH: 20.4% vs 58.3%; RR, 0.35; 95% CI, 0.17 to 0.71) and periventricular leukomalacia (PVL: 27.8% vs 58.3%; RR, 0.48; 95% CI, 0.25 to 0.91) in the MgSO4 group compared with no MgSO4 group. And the incidence of developmental delay in the subgroup of 23-27 weeks’ gestation was significantly lower in the MgSO4 group (6.5% vs 36.4%; RR, 0.18; 95% CI, 0.05 to 0.69). A similar trend was observed for cerebral palsy, with 22.2% of unexposed children affected compared with only 7.7% of exposed children. However, there were no significant differences in the development of IVH, PVL, developmental delay, and cerebral palsy between the two groups for patients in the subgroup of 28-31 weeks’ gestation. 결론: Antenatal MgSO4 in women with PROM remote from term could prolong pregnancy, allowing for corticosteroid benefit without significant increase in the risk of neonatal morbidities and chorioamnionitis. Moreover, MgSO4 therapy had fetal neuroprotective effects for neonatal IVH and PVL, and for developmental delay in infancy and cerebral palsy in early childhood, especially in women with PROM at 23-27 weeks’ gestation.

Labial Adhesions Caused by Stevens-Johnson Syndrome

( Eun Jeong Jeong ),( Dae Hoon Jeong ),( Young Nam Kim ),( Su Sun Kim ),( Moon Su Sung ),( Kyung Bok Lee ),( Ki Tae Kim ),( Jung Mi Byun ) 대한산부인과학회 2012 대한산부인과학회 학술대회 Vol.99 No.-

Stevens-Johnson syndrome is a rare, life-threatening condition characterized by epidermal necrosis and involvement of the mucosal surfaces. Stevens-Johnson syndrome (SJS) is caused by abnormal immunologic reactions, normally after exposure to drugs or infections. The condition is characterized by the rapid development of widespread epidermal necrosis. The primary lesions are usually irregular target lesions or flat purpuric macules involving the trunk, face, and proximal limbs. The cutaneous necrosis is associated with involvement of the mucosal surfaces and severe constitutional disturbance. Extensive labial sinechiae in such patients can cause dysuria, urinary tract infection, and sexual dysfunction. Treatment is symptomatic, apart from treating the causing infection and elimination the causative drugs. The use of corticosteroids and immunoglobulins is controversial. Genital sequelae of SJS in females has been recognized but have not been well studied. We report a case of Stevens-Johnson syndrome with labial involvement in an 25-yr-old woman. We recommend that all patients with Stevens-Johnson syndrome with vaginal involvement undergo routine follow-up to evaluate possible adhesions.

The patient was a 22-year-old woman, who presented with abdominal pain and palpable huge mass. The initial investigation by ultrasound examination showed a huge size heterogenous soild mass and then magnetic resonance imaging presented multilobulated, huge solid mass (16×13 cm) with heterogenous enhancement in left ovary. Serum calcium level was slightly elevated (10.6 mg/dL, normal less than 10.4 mg/dL) and cancer antigen 125 level was normal. She underwent a laparotomy and left salpingo-oophorectomy. Grossly, ovary consists of yellowish solid portion but not cystic portion and outer capsule was ruptured focally. The pathologic finding, including immunohistochemical finding, confirmed small cell carcinoma, hypercalcemic type from ovary. Now, She has been treated with adjuvant chemotherapy (cisplatin, adriamycin, etoposide, cyclophophamide). We report this case with brief review of literature.
