Soo In Kim,Kyoung Ae Kong 대한신경정신의학회 2020 PSYCHIATRY INVESTIGATION Vol.17 No.4

Objective We examined the performance of attention tests related to suicidal ideation in mood disorder patients and to explain the difference of attention test performance in relation to suicidal ideation after controlling clinical and psychological variables of mood disorder patients. Methods Seventy-three in- and outpatients with major depressive disorder (n=41) or bipolar disorder (n=32) completed a self-rating questionnaire assessing socio-demographic characteristics, and clinical and psychological variables. Comprehensive Attention Test (CAT) also was conducted. Results Thirty-three patients were the high-suicidal ideation (SI) group, and forty patients were the low-SI group. The errors of commission (CEs) of visual sustained attention in the high-SI group was 6.3 times higher on average than that of the low-SI group. After controlling for sex, age, and diagnosis, a higher number of CEs on visual sustained attention tasks predicted higher SI score. However, after controlling for sex, age, diagnosis, and depressive mood, this predictive ability was no longer observed. Conclusion This study showed that CE on the visual sustained attention task seems to influence suicidal ideation as a result of interaction with depressive symptoms.

I analyzed how the case law theory on three steps has been formed and changed along with historical background and dependance path main causes. The first case law theory is the discrimination and separate step on unfair relation between white majority and black minority(1890-1940), and the second case law theory is further advanced but weak remedy against discrimination(1940-1964) step, and the third case law theory is positive remedy against discrimination (1964-1989) step with the result equality, Affirmative Action. I analyzed the dependance path main causes on Lock in-Effect in which the case law theory controls the actors and minority and majority, so it effects on the delayed and retard speed for equality. In Conclusion, Judicial judgment is the same as for minority promotion for human rights, and then main majority is available to access the political socialization and make political culture to the completed democracy value. Also, I drew the proper implication on the Korean muticultural policy from the American history and evidence.

이 연구는 스텐트 내 재협착 병변에서 약물용출 풍선 확장술을 시행한 환자를 대상으로 주요 심장사건에 영향을 미치는 예측 인자가 무엇인지 알아보고자 하였다. 2012년 10월부터 2017년 1월까지 전남대학교병원 심혈관센터에서 경피적 관상동맥 삽입술 후 스텐트 내 재협착이 발생한 환자 중에서 약물용출 풍선 확장술을 시행 받은 환자 257명 (평균연령 66.1±10.1세, 남자 172명)을 대상으로 그룹 I (주요 심장사건 발생군, n=35명), 그룹 II (주요 심장사건 발생하지 않은 군, n=222명)로 나누어 분류 하였다. 약물용출 풍선 성형술 후 주요 심장사건의 독립적인 예측 인자를 보기 위한 다변량 분석에서 완전 폐쇄병변 형태의 재협착 형태 (HR=4.179, 95% C.I.=1.851-9.437 p= 0.001), 25 mm이상의 긴 병변 (HR=8.773, 95% C.I.=1.898-40.546 p= 0.005), 반복되는 스텐트 내 재협착 (HR=4.693, 95% C.I.=1.259-17.490 p= 0.021)이 독립적인 예측 인자로 판명되었다. The aim of this study was to investigate the predictors of major adverse cardiac events (MACE) in patients with drug-eluting balloon (DEB) for in-stent restenosis (ISR) lesion. Total of 257 patients who developed ISR on follow-up coronary angiography (66.1 ± 10.1years, 172 males) in Chonnam National University Hospital between October 2012 and January 2017 were enrolled. We divided the patients into two groups; group I (MACE group; n= 35) and group II (No MACE group; n= 222). A multivariate logistic regression analysis revealed that type IV ISR (HR=4.179, 95% C.I.=1.851-9.437 p= 0.001), lesion length > 25 mm (HR=8.773, 95% C.I.=1.898-40.546 p= 0.005), number of ISR recurrence > 2 (HR=4.693, 95% C.I.=1.259-17.490 p= 0.021) were independent factors for MACE after DEB in ISR lesions.

The reimaging optics of the KASINICS (KASI Near Infrared Camera System) includes many transparent components like an entrance window, band-pass filters, and blocking filters. As observational targets or in-field background objects, bright stars may cause optical ghosts that can significantly degrade the system performance of the KASINICS. We estimated analytically the relative brightness of ghost components with respect to a point source and examined the effects of tilting optical components as a method of suppressing ghosts. We also performed numerical ray tracings including all the optical components and found the results are consistent with those of the analytic estimations. We conclude that the KASINICS will not suffer from significant ghost effects with appropriate anti-reflection coatings and fittings for the optical components.

Effect of Temperature Shock on Cultured Olive Flounder(Paralichthys olivaceus) and Black Rockfish(Sebastes schlegeli)

KONG, IN SOO,LEE, SANG JUN,Lee, Jeong Ho,Kim, Yoon,Lee, Jong Hee,Min, Kwang Sik,Kang, Jeong Ha,Myung, Jeong In 한국수산학회 2001 Fisheries and Aquatic Sciences Vol.4 No.3

Aim of this research is to investigate the effect of temperature shocks on the physiological responses of cultured olive flounder (Paralichthys olivaceus) and black rockfish (Sebastes schlegeli). Olive flounder and black rockfish were suffered with high and low temperature shocks for 4 and 8 h, respectively, in laboratory conditions and then the changes in glucose, lactate, total protein, uric acid, and triglycerides-glycerol in blood plasma were analyzed. We observed that lactate and uric acid increased for up to 4 h and then decreased for up to 8 h by the high and low temperature shocks, and total protein decreased for up to 4 h and then recovered for up to 8 h by the high temperature shock in both fishes. Glucose by the high and low temperature shocks and triglycerides-glycerol by the low temperature shock increased for up to 4 h, and then decreased in olive flounder, but increased for up to 8 h in black rockfish. From the result, we speculated that the two fishes have an interspecific variation in the regulatory systems of glucose and triglycerides-glycerol. Glucose would play important role as an energy source during the temperature shocks and for an intermediate substance for low temperature tolerance, and glycerol of triglycerides-glycerol would play an important role for low temperature tolerance. In olive flounder, the turnover of chemical change by temperature shock took more than 4 h, all chemicals returned almost to the initial level for up to 8 h, but fish death followed only in 8 h with the high temperature shocked group within two days. Therefore, we suggested that fish would be damaged severely by the longer time exposure of high temperature and mortality would occur after a certain time later than the shocked time as a post-effect.

Seismic stratigraphy and structural characteristics of the northeastern continental margin of Korea in the East Sea (Sea of Japan)

Cukur, Deniz,Um, In-Kwon,Bahk, Jang-Jung,Chun, Jong-Hwa,Horozal, Senay,Kim, So-Ra,Kong, Gee-Soo,Kim, Kyong-O.,Kim, Seong-Pil Elsevier 2018 Marine and petroleum geology Vol.98 No.-

<P><B>Abstract</B></P> <P>The northeastern continental margin of Korea in the East Sea (Japan Sea) is a narrow sedimentary apron 20–30 km wide, 50–1300 m below sea level, with an average gradient of less than 2°. The present study focuses on seismic stratigraphy of the sedimentary section and the underlying basement structure of the margin based primarily on multi-channel seismic reflection profiles. Major accumulation of sediment is centred in a graben depocenter in the northern part of study area, where more than 2 km of sediments have been deposited. This graben widens towards north and is flanked by two major basement bounding faults. The sedimentary succession of the margin can be divided into six seismic stratigraphic units based on reflection character, onlapping, and erosional truncation. The lowermost seismic unit (SU1) is characterized by parallel-to subparallel-reflections with varying amplitudes and is interpreted to be representing shallow-to non-marine sediments that were deposited during the active extensional phase of margin development. The presence of erosional channels in the uppermost section of SU1 further suggests a lowstand period after the deposition of SU1. Unconformably overlying the SU1 is a few hundred metres of SU2 that is characterized by continuous, high-amplitude reflections. Continuous seismic reflections within SU2 are indicative of sea level rise immediately following the lowstand period. The overlying seismic unit sets include SU3, SU4, and SU5 with well-stratified seismic reflections. The consistent reflection pattern and high continuity of the reflections within these units are indicative of relatively stable depositional environments within the margin. Hemipelagic sediments and turbidites are probably the main components of these units. The youngest seismic unit SU6 comprises well-stratified seismic reflections in the upper slope and chaotic-to transparent-seismic reflections in the lower slope. The sedimentary units characterized by well-stratified seismic reflections are typical for hemipelagic slope sediments while chaotic seismic reflections are diagnostic features for mass-transport sediments (MTDs; i.e., slides/slumps, debris-flow deposits). The preferential occurrence of MTDs adjacent to the major faults suggests that they may be due to earthquakes associated with tectonic activity.</P> <P>Seismic reflection data from the margin reveal the coexistence of four structural styles including the basement-involved normal faults, reverse faults, reactivated normal faults, and anticline folds. The basement-bounding normal faults are associated with the initial extension of the continental margin while the others are postulated as resulting from contractional tectonism of the eastward movement of the Amur Plate that began in the early Pliocene. The prominent seafloor erosion over the folded/inverted blocks further suggests that inversion continues today.</P> <P><B>Highlights</B></P> <P> <UL> <LI> A tectonostratigraphic framework for the northeastern margin of Korea is developed. </LI> <LI> Six seismic units have been defined in analysis of the seismic reflection profiles. </LI> <LI> Primary deposits consist chiefly of hemipelagites interbedded with turbidites. </LI> <LI> Basement structure and seismic stratigraphy suggest a rift origin for the margin. </LI> <LI> Regional compression in the Pliocene reactivated the earlier extensional faults. </LI> </UL> </P>

<P> Decreased cardiac contractility occurs in endotoxicosis, but little is known about the ionic mechanism responsible for myocardial dysfunction. In this study, we examined the changes in Ca<SUP>2⁢</SUP> and K<SUP>⁢</SUP> currents in cardiac myocytes from endotoxin-treated rat. Ventricular myocytes were isolated from normal and endotoxemic rats (<I>ex vivo</I>), that were treated for 10 hours with <I>Salmonella enteritidis</I> lipopolysaccharides (LPS; 1.5 mg/kg) intravenously. Normal cardiac myocytes were also incubated for 6 hours with 200 ng/ml LPS (<I>in vitro</I>). L-type Ca<SUP>2⁢</SUP> current (I<SUB>Ca,L</SUB>) and transient outward K<SUP>⁢</SUP> current (I<SUB>to</SUB>) were measured using whole cell patch clamp techniques. Peak I<SUB>Ca,L</SUB> was reduced in endotoxemic myocytes (<I>ex vivo</I>; 6.00.4 pA/pF, P<0.01) compared to normal myocytes (control; 10.90.6 pA/pF). Exposure to endotoxin <I>in vitro</I> also attenuated I<SUB>Ca,L</SUB> (8.40.4 pA/pF, P<0.01). The amplitude of I<SUB>to</SUB> on depolarization to 60 mV was reduced in endotoxin treated myocytes (16.51.5 pA/pF, P<0.01, <I>ex vivo</I>; 20.00.9 pA/pF, P<0.01 , <I>in vitro</I>) compared to normal myocytes (control; 24.71.0 pA/pF). There was no voltage shift in steady-state inactivation of I<SUB>Ca,L</SUB> and I<SUB>to</SUB> between groups. These results suggest that endotoxin reduces Ca<SUP>2⁢</SUP> and K<SUP>⁢</SUP> currents of rat cardiac myocytes, which may lead to cardiac dysfunction.

목적: 제대동맥 도플러혈류속도파형이 저체중태아를 동반한 만기임신의 주산기 예후예측에 유용한가를 살펴보고자 한다. 연구 방법: 임신 37주부터 41주 사이에 단태의 저체중태아를 분만한 산모와 신생아의 의무기록을 후향적으로 검토하였다. 총 381명의 단태임신 환자의 최고 수축기혈류속도 (S)에 대한 이완기 말 혈류속도 (D)의 비를 측정하여 S/D치 3.0 이하인 정상군(n=307)과 3.0 초과인 비정상군(n=74)으로 구분하여 산모의 임상적 특징 및 신생아 예후를 비교하였다. 결과: 두 군 모두에서 산모 연령, 분만 시 재태연령, 태아곤란증에 의한 제왕절개분만 빈도 등에서 차이를 보이지 않았다. 제대동맥 도플러지수가 비정상인군에서 산모의 고혈압성 질환의 빈도(12.3% vs. 25.0%, P=0.005)가 통계학적으로 유의하게 높았다. 신생아 출생체중(2,415.2±258.9 g vs. 2,296.7±325.0 g, P=0.003), 신생아의 중환자실 입원 빈도(27.0 vs. 51.3%, P<0.001) 및 중환자실 입원기간(2.7±5.9 vs. 5.7±8.8 days, P=0.005) 등은 유의한 차이를 보였으나, 7 미만의 낮은 5분 Apgar치, 기계적 호흡빈도, 주산기사망 및 신생아 합병증 등은 차이를 보이지 않았다. 선형회귀분석을 시행한 결과 고혈압성 질환의 빈도를 보정한 후에도 비정상 제대동맥 도플러지수와 작은 출생 시 신생아체중은 유의한 관계가 있었다(P<0.001). 결론: 제대동맥 도플러 혈류 파형이 만삭 임신에 동반된 저체중태아의 신생아 체중, 신생아 중환자실 입원빈도 및 입원기간 등을 예측하는데 유용한 독립인자로 작용하지만 그 외의 신생아 예후 예측에는 한계가 있으므로 자궁동맥혈류파형이나 정맥관, 중뇌혈관 등과 같은 다른 혈관의 도플러혈류파형 측정이나 생물리학적계수 등을 종합하여 주산기 합병증을 낮추도록 해야 할 것이다. Objective: To investigate whether umbilical artery Doppler blood flow velocity waveform is effective in predicting perinatal outcome of term pregnancies with small for gestational age (SGA). Methods: A total of 381 patients at 37~41 weeks of gestational age (GA) who received antenatal umbilical artery Doppler blood flow test and delivered singleton SGA infants. The ratio of peak-systolic to end-diastolic (S/D) blood flow velocities in the umbilical artery was measured in each patient. The patients were divided into a normal group (n=307) with a S/D ratio equal to or less than 3.0, and an abnormal group with a S/D ratio of greater than 3.0 (n=74). These groups were comparatively analysed with respect to maternal characteristics and neonatal outcomes. Results: There were no significant differences between the two groups in mean maternal age, gestational age at the time of delivery, and cesarean section rate due to fetal distress. There was significantly increased incidence of hypertensive disorders in pregnancy in the abnormal S/D ratio group. And the abnormal S/D ratio group showed lower neonatal birthweight, higher incidence of admission to neonatal intensive care unit (NICU), and longer stay in neonatal intensive care unit. According to linear regression, in pregnancies complicated by SGA, abnormal S/D ratio was still a risk factor for low birthweight even after controlling for the incidence of hypertension. Conclusion: In term pregnancies accompanied by SGA, abnormal umbilical artery S/D ratio is an independent predictor of neonatal birth weight, incidence of admission to NICU, and NICU stay.

목적: The aim of present study was to evaluate the perinatal outcomes of selective intrauterine growth restriction (sIUGR) and non-selective IUGR (non-sIUGR) in twin pregnancy. 방법: This was a retrospective study of twin pregnancies from 2007 to 2014. A total number of 385 pairs of twin born between 2007 and 2014 at Ajou University Hospital were enrolled in the study. According to the birth weight, the 385 pairs of twins were divided into sIUGR, non-sIUGR, and normal growth groups. Maternal characteristics and perinatal outcomes were compared among three groups. 결과: Among 385 twin pregnancies, 80 (20.8%) were sIUGR, 15 (3.9%) were non-sIUGR, and 290 (75.3%) were normal growth group. There was no significant difference between IUGR and sIUGR groups according to chorionicity (p=0.417). Vaginal delivery was significantly higher in non-sIUGR group compared to sIUGR and normal growth groups (46.7% vs. 16.2% vs. 14.5%, p=0.014). The incidence of fetal distress and chorioamnionitis were higher in the non-sIUGR group than in sIUGR and normal growth groups (fetal distress: 20.0% vs. 2.5% vs. 1.4% , p<0.001, chorioamnionitis: 53.0% vs. 30.0% vs. 21.7%, p=0.004). Maternal preeclampsia was higher in IUGR group (sIUGR and non-sIUGR) than in normal growth group (18.8% vs. 26.7% vs. 9.3%, p=0.004). With respect to perinatal outcomes, perinatal death was higher in sIUGR group than in normal growth group (10.6% vs. 4.8%, p=0.006). The incidence of poor perinatal outcome (any of the followings: NEC, BPD, RDS, and brain hemorrhage) was higher in both s-IUGR and non-sIUGR groups than in normal growth group (17.6% vs. 23.3% vs. 11.3%, p=0.007). 결론: There was significant difference between sIUGR and non-sIUGR groups in terms of vaginal delivery, fetal distress, and chorioamnionitis. Poor perinatal outcome was higher in both non-sIUGR and sIUGR groups compared to normal growth group.

The immobilization of a microorganism has been rapidly progressed with the development of biotechnology in recent years. Although it has been used as a tool to isolate products from biological media in various areas, it has not yet been practiced in the treatment of waste water. In this paper, we suggest a possibility to apply the immobilization technique in the recirculating aquaculture system. We examined the ability of NH₄^+ removal by nitrifier consortium immobilized in Ba^(++)-alginate, κ-carrageenan and agar bead at the concentration of 50g/L, respectively. In order to use the immobilized nitrifier consortium as media in the fludized bed reactor, the strength of bead was measured. Ba^(++)-alginate as a support material showed higher strength of bead. Also, the nitrifier consortium immobilized in Ba^(++)-alginate showed higher nitrification activity that could remove 20㎎/L ammonium ion than those immobilized in other two support materials, carrageenan and agar. The immobilized nitrifier consortium showed better nitrification activity than free nitrifier consortium.
