오승용 한국수산과학회 2023 한국수산과학회지 Vol.56 No.5

The effect of bio-logger tagging location on blood characteristics and bio-logger attachment efficiency in spotted sea bass (mean body weight 2356.7 g) was investigated. The fish were tagged at four different tagging locations: no-tag (control), operculum attachment (OA), dorsal muscle attachment (DA), and cauda peduncle muscle attachment (CA). The blood properties and bio-logger attachment efficiencies were examined on days 1, 7, 14, and 35 after tagging the bio-logger at each tagging location. During the experimental periods, the concentrations of hematocrit and hemoglobin in whole blood, and GOT (glutamic oxaloacetic transaminase), GPT (glutamic pyruvic transaminase), total protein (TP), glucose, total cholesterol, cortisol, and superoxide dismutase in plasma were not affected by the attachment location of the bio-logger, however, the TP concentration was significantly lower in OA than in the control group on day 7. After tagging for 35 days, the efficiencies of bio-logger attachment in the OA, DA, and CA after tagging for 35 days were 33.3%, 100.0%, and 33.3%, respectively. These results indicate that, in our experimental condition, the most appropriate bio-logger attachment location is DA, providing basic information on bio-logger utilization methods for ecological and biological biotelemetry surveys of the spotted sea bass.

호남 정치의 변화: 제19대 대통령선거를 중심으로

오승용,조정관 한국NGO학회 2017 NGO연구 Vol.12 No.3

This study describes both the background and the process in Honam(Southwestregion of South Korea) of the 19th presidential election in 2017, and analyzes itsresults by utilizing various survey data. This study wonders why the high popularsupport in Honam of Kukmin Party(People’s Party) shown in the preceding 20thNational Assembly elections faded away so drastically. It finds that the 2016“Rebate” corruption case and the presidential impeachment process in turn havecontributed to the change a lot. The presidential election was heavily affected by the impeachment process anda series of candle-light mobilizations. Ideological inclination is found to be adecisive factor in choosing presidential candidates. The progressive civil society,having been negative to the opposition party’s split, was invigorated by themobilizations and became strongly supportive to the Democratic Party whichpromised a clear transfer of government between political powers. In ballots,Honam voters turned out to be less homogeneous than before. There seems to bechances of realigning political parties. The existing regional party system may bereplaced by a more ideological party competition if Ahn Cheol Soo’s attempt toset up a party with centrism is successful.

오승용,장요순,박흥식,최영웅,김종관 한국해양과학기술원 2012 Ocean and Polar Research Vol.34 No.1

The effect of water temperature and body weight on oxygen consumption by the fasted olive flounder Paralichthys olivaceus was investigated in order to assess the metabolic rate of this species under different conditions. The oxygen consumption rate (OCR) was measured at three different water temperatures (15, 20 and 25oC) and two different body weights [9.1±1.2 g (mean±SD) for the juvenile group and 266.4±29.3 g for the immature group] at an interval of 5 minutes for 24 hours using a closed flow-through respirometer. For each treatment condition, three replicates were set up and 135 fish in the juvenile group and 18 fish in the immature group were used. The OCRs exhibited a linear increase described by OCR=−82.06+28.30T (r2=0.96, p<0.001) in the juvenile group and OCR=−52.52+14.73T (r2=0.97, p<0.001) in the immature group. The OCRs decreased with increasing body weights at a given water temperature (p<0.001). The metabolic rate was related to the body weight of the fish as a power function with a weight exponent of between 0.77 and 0.82. Q10 values ranged 1.67~2.28 when the temperature was between 15 and 20oC, 1.57~1.93 when the temperature was between 20 and 25oC, and 1.79~1.89 when the temperature was between 15 and 25oC. The energy expenditure by respiration increased with increasing water temperature and decreasing body weight (p<0.001). The mean energy loss rates at 15,20 and 25oC were 115.9, 149.8 and 208.2 kJ kg−1d−1in the juvenile groups and 53.8, 81.2 and 101.9 kJ kg−1d−1 in the immature groups.

종교 코드를 통해 읽는 5·18항쟁

오승용 광주가톨릭대학교 신학연구소 2014 神學展望 Vol.- No.185

종교 스펙트럼을 통해 읽는 5·18항쟁은 매우 흥미로운 주제지만 연구가 충분하진 않다. 종교와 국가와의 관계만큼 종교와 민중항쟁의 관계가 평범하진 않다. 본질적으로 국가와 종교의 관계는 대립적이라기보다는 균형 지향적일 수밖에 없다. 국가 혹은 체제에 반하는 종교가 존립하기 위해서는 상상할 수 없는 탄압과 박해, 고통을 감내해야 한다. 국가와 종교가 충돌하는 지점은 신앙의 자유 영역이 아닌 ‘신앙 실행의 자유’ 영역이다. 신앙 실행의 자유는 종교 활동이나 행사를 통해 신앙을 실천하는 자유 곧 종교적인 확신에 따라 행동하고 교리에 따라 생활할 수 있는 자유를 말한다. 종교는 신앙 실행의 자유를 통해 국가와 국가의 정책, 국가의 담지자인 정권과 긴장관계를 형성해 왔다. 5·18항쟁과 종교가 만나는 지점, 5·18항쟁과 가톨릭이 만나는 지점이 정확히 이 부분이다. 국가에 저항하는 광주 시민과 가톨릭의 만남을 연결시켜주는 접착제가 신앙 실행의 자유였다. 5·18 당시 가톨릭교회는 계엄군의 강경진압에 항의하고, 이를 광주 이외 지역에 알리는 활동을 담당했다. 그리고 시민들과 함께 직접 투쟁에 참여하기보다는 그들을 간접적으로 지원하는 ‘구호’ 활동을 주로 담당했다. 그러나 오월 진상규명 운동을 가장 주도적으로 해나가며, 한국의 민주화운동에 있어 큰 역할을 해왔다. 가톨릭교회의 이와 같은 활동과 역할이 ‘부끄러움’과 ‘산 자의 의무’에서 이루어진 것인지, 종교적 신념과 신앙 실행의 자유에서 이루어진 것인지를 정확하게 구분할 수는 없지만, 5·18항쟁과 오월진상규명 활동에 있어 가톨릭교회의 활동을 드러내는 데는 전혀 문제가 없다. 5·18항쟁을 계기로 가톨릭교회는 군사정권의 국가안보 이데올로기와 정면충돌하고 독재정권 또는 군사정권의 지배방식을 거부하면서도 교회운동의 반공주의적 성격을 분명히 하였다. 부산미문화원방화사건을 계기로 권위주의 정권의 교회 일부에 대한 이데올로기적 공세는 가톨릭교회와 정부가 정면충돌하는 계기가 되었고, 가톨릭교회의 상대적 급진화를 초래하는 원인이 되었다.

조피볼락 Sebastes schlegelii의 생존율, 산소 소비율과 혈액 성상에 미치는 염분의 영향

오승용,김종관,장요순,최희정,명정구 한국해양과학기술원 2014 Ocean and Polar Research Vol.36 No.2

The effect of salinity on the survival, oxygen consumption and blood physiology of Korean rockfish Sebastes schlegelii (body weight 97.4 ± 1.7 g, mean ± SD) was investigated at nine different salinities of 33.4 (control), 33.1, 32.8, 32.2, 31.0, 28.7, 23.9, 14.5 and 3.8 psu, respectively. Survival and blood physiology were measured at each salinity in two separate trials of 96 and 24 hr duration, respectively. Oxygen consumption rate (OCR) was determined at stepwise salinity exposure (33.4→33.1→ 32.8→32.2→31.0→28.7→23.9→14.5→3.8 psu) with an interval of 24 hr for each salinity. No death of fishes were observed in the range of 33.4 to 14.5 psu, but the survival rate was reduced to 26.7% at 3.8 psu after 96 hr. The OCRs were not significantly different in the range 33.4 to 28.7 psu (p > 0.05), but significantly increased until 14.5 psu and then drastically decreased at 3.8 psu compared to the control (p < 0.05). The concentrations of plasma Na+ and Cl− were significantly lower in fish exposed at 3.8 psu compared to the control (p < 0.05). The results of this study provide evidence that S. schlegelii exposed to concentrations below 23.9 psu show significant physiological responses to tolerate salinity changes under the experimental conditions we established.

오승용,지익성,이영호 대한신경정신의학회 2001 신경정신의학 Vol.40 No.1

연구목적: 최근 5-HT□수용체 유전자 promoter의 -1438A/G 다형성이 보고되었고, 이러한 -1438A/G 다형성이 기분장애와 연관이 있는지 알아보려는 연구가 시도되고 있다. 저자 등은 -1438A/G 다형성이 한국인 양극성 장애의 발병에 있어서 유전적 요인으로 작용하는지 알아보기 위하여 본 연구를 시행하였다. 방법: 양극성 장애 환자 120명과 정상 대조군 120명을 대상으로 중합효소 연쇄반응을 이용하여, 5-HT□ 수용체 유전자 promoter -1438A/G 다형성의 유전자형과 대립유전자의 빈도를 비교하였다. 결과: 1) 양극성 장애 환자군의 5-HT□수용체 유전자 promoter -1438A/G 다형성의 유전자형은 A/A 14(12%), A/G 66(55%), G/G 40(33%), 정상 대조군의 유전자형 A/A 30(25%), A/G 59(49%), G/G 31(26%)로 양군간에 유의한 차이가 있었다. 2) 대립유전자의 빈도는 양극성 장애 환자군에서 A 0.39, G 0.61, 정상대조군에서 A 0.49, G 0.51로 양군간에 유의한 차이가 있었다. 결론: 5-HT□ 수용체 유전자 promoter -1438A/G 다형성이 한국인 양극성 장애의 발병과 연관이 있을 수 있다는 가능성을 제시한다. Objectives : This study was designed to investigate the association between 5-HT□ receptor gene promoter -1438A/G polymorphism and bipolar disorder in a Korean population. Methods : 5-HT□ receptor gene promoter -1438A/G polymorphism were typed with Po-lymerase Chain Reaction in 120 patients with bipolar disorder and 120 normal controls. Results : The distributions of the genotype in the bipolar disorder with A/A, A/G, G/G were 14(12%), 66(55%), 40(33%), and in the controls were 30(25%), 59(49%), and 31(26%). The allele frequencies of the bipolar disorders with A and G were 94(39.2%), 146(60.8%), and in the controls were 119(49.6), and 121(50.4), respectively. There were significant differences in genotype distributions and allele frequencies of -1438A/G between patients with bipolar disorder and normal controls. Conclusion : These results suggest that 5-HT□ receptor gene promoter -1438A/G poly-morphism may be related to the development of bipolar disorder in a Korean population.

대구 Gadus macrocephalus 치어의 산소 소비율에 미치는 수온과 광주기의 영향

오승용,박흥식,김종관 한국해양과학기술원 2010 Ocean and Polar Research Vol.32 No.3

A study was conducted to investigate the effect of water temperature and photoperiod on the oxygen consumption of the fasting juvenile Pacific cod Gadus macrocephalus (mean body weight 79.9± 2.0 g) in order to quantify metabolic response of the species under given conditions. The oxygen consumption rate (OCR) of G. macrocephalus was measured under a combination of four different water temperatures (7, 10, 13 and 16℃) and three different photoperiods (24L:0D, 12L:12D and 0L:24D) with an interval of 5 minutes over a 24-hour period using a closed recirculating respirometer. Three replicates were set up in each treatment. OCRs increased with increased water temperatures under all photoperiod conditions (P<0.001). Mean OCRs at 7, 10, 13 and 16℃ ranged from 793.7~1108.4, 1145.7~1570.3,1352.8~1742.5 and 1458.2~1818.6 mg O2 kg−1 h−1, respectively. Under all water temperature conditions except 7oC (P<0.001), mean OCRs of G. macrocephalus were the highest in continuous light (24L:0D) followed by 12L:12D and 0L:24D photoperiods. Mean OCRs of fish exposed to the 12L:12D photoperiod were significantly higher during the light phase than during the dark phase under all temperature conditions (P<0.001). Q10 values ranged from 3.19~5.13 between 7 and 10oC, 1.41~1.74 between 10 and 13℃ and 1.15~1.35 between 13 and 16℃, respectively. Based on overall results, water temperature, photoperiod and their combinations exerted a significant influence on the metabolic rate of juvenile cod. This study provides empirical data for estimating the amount of oxygen demand and managing the culture of cod under the given water temperatures and photoperiods.
