본 연구에서는 1985년부터 2001년까지 17년간의 황아귀 어획량 및 노력량 자료와 어획물 체장조사 자료를 이용하여 한국 연근해 황아귀 자원에 대한 자원생물학적특정치를 추정하였다. 어획물곡선을 이용하여 추전된 한국 연근해 황아귀의 순간전 사망계수 (Z)는 0.91/년이며, 어구가입연령 (t_(c))은 1.3세였다. 또한, 자연사망계수 (M)는 0.27/년으로, 순간어획사망계수 (F)는 0.64/년으로, 어장가입연렁(t_(r))은 0.3세로 추정되었다. 황아귀 자원을 가입당생산량 모델에 적용시킨 결과, 가능한 최대 가입당생산량이 948g 임에 비하여 현재의 t_(c) = 1.3세, F = 0.64/년에서의 가입당생산량은 559g 정도로 나타났다. 여기서 t_(c)를 현재 상태로 고정시킨 후, 가입당생산량을 높이는 방안을 생각해 보면, 현재의 F 값 0.64/년에서 증가할수록 가입당생산량은 감소하는 경향을 보이고 있지만, 현재의 어획강도 (F)를 고정시키는 경우에는 t_(c)를 현재의 1.3세에서 4세 부근으로 조정하면 최대의 가입당생산량(948g)을 얻을 수있고, 이 t_(c)값은 역시 F_(0.1)방법에서 추정된 적정 어획체장음 연력으로 환산한 결과와 거의 일치하였다. 또한, 가입당생산량 및 가입당산란자원량 모델을 이용하여 생물학적 관리기준점이 되는 F_(0.1)과 F_(35%) 및 F_(40%)을 각각 0.14/년, 0.26/년, 0.22/년으로 설정하였다. 지난 17년간 어획자료를 사용하여 잉여생산모델에 의해 추정된 MSY는 Schaefer와 Fox 모델에 의하여 각각 7.740톤과 7.720톤으로 유사한 결과를 나타냈다. 또한, CPUE/CPUE_(M8Y) 비는 1보다 큰 값을 보여 황아귀의 자원상태는 한국 TAC 산정을 위한 ABC 추정시스템의 4a 단계에 해당되었다. 따라서, MSY 및 자원상태를 고려하여 한국 연근해 황아귀 자원의 2002년도 관리시점의 생물학적허용어획량은 7,730톤이 적정한 것으로 판단되었다. The purpose of this study is to estimate population ecological parameters, including instantaneous coefficients of natural and fishing mortalities, and age at first capture, as well as to carry out stock assessment of yellow goosefish Lophius litulon (Jordan) in Korean wafers. Using the catch curve, the instantaneous coefficient of total mortality (Z) of yellow goosefish was estimated at 0.91/year and the age at first capture. 1.3 years. The instantaneous coefficients of natural and fishing mortalities (M and F) were estimated to be 0.27/year and 0.64/year, respectively. A yield-per-recruit (YPR) analysis showed that the current yield per recruit of about 559 g with F of 0.64/year at t_(c) of 1.3 years. was lower than the possible maximum yield per recruit of 948 g. With to fixed at the current level, the yield per recruit tended to decrease as the current F (0.64/year) value increased. Thus, it is suggested that the maximum yield per recruit can be attained with a fixed F value at the current level by increasing t_(c) from 1.3 rears to 4.0 years. Based on YPR and spawning biomass per recruit (SPR) models, the biolegical reference points, such as F_(0.1), F_(35%), F_(40%), were suggested as 0.14, 0.26, 0.22 per year at current age 1 of recruitment. Employing surplus production model (SPM) with catch per unit effort of the Korean large stow net fishery during the periods of 1985-2001, the estimated MBYs were similar between the Schaefer and Fox models, ranged from 7,74D to 7,720 mt. Finally, we suggested that acceptable biological catch (ABC) of yellow goosefish in 2002 should be 7,730 mt, based on the MSY and the current status of the stock in Korean waters.

Doo Chull Shin(申斗澈),Moon Kap Joo(朱門甲) 한국육종학회 1986 한국육종학회지 Vol.18 No.4

This study was conducted to confirm the germinability of unripened seeds for rapid generation advancement of soybean in field and greenhouse. Seed development and germinability were faster in greenhouse than in field, and in the early variety than in the late variety. The first germinabilities were found on the 20 days after flowering(DAF) in greenhouse materials, and on the 20 to 25 DAF in field materials. It was found that over 90 percentage of germination on 10 to 20 days before maturity of soybean in field and greenhouse, and this ripening stage was corresponded with the time when the fresh pod weight reached at the highest level. The germination ratio of the seeds dried with pod shell was the almost same level with that of the fresh seeds ripened for 10 to 15 days more. The germination ratios of the dried seeds which were harvested on 20 to 25 days before maturity in each cultivar were over 80 percentage.

Doo Chull Shin,Arnold T. Tschanz 韓國作物學會 1986 한국작물학회지 Vol.31 No.4

열대 및 아열대지역의 대두재배에서 수량을 격감시키고 있는 콩녹병에 대한 내병성품종과 이병성품종을 공시하여, 본 병해의 진전과정과 생리적 및 수량관련형질에 미치는 영향을 검토한바 그 결과를 요약하면 마음과 같다. 1. 이병성품종은 내병성품종에 비하여 병의 조기감염 및 진전이 빨랐으며, 녹병에 의한 낙엽은 콩 꼬투리가 반정도 등숙된 후부터 급격히 증가하였다. 2. LAI의 감소는 이병성품종이 내병성품종에 비하여 빨랐으며, 건전개체와 녹병 이병개체간의 엽녹소함양의 차리는 내병성품종에서 2.04%, 이병성품종에서 16.43%의 차이가 있었다. 3. 지상부 건물중은 녹병무발병구(살균제 처리구)에서는 계속 증가하였으나, 녹병발병구에서는 R6 생육단계 이후부터 감소하였고, 감소정도는 이병성품종이 내병성품종에 비하여 더 컸다. 4. 협과 종실의 건물중은 이병성품종의 녹병무발병구에서는 R6생육단계 이후에 급격히 증가하였으나, 녹병발병구에서는 아주 완만하게 증가하였고, 내병성품종에서는 녹병의 영향을 적게 받아 녹병발병구에서 계속 큰 폭으로 증가하였다. 5. 녹병은 불완전립과 빈 꼬투리 수를 증가시키고, 종실의 Oil 함양 및 길이, 폭, 두께를 감소시키며, 협수, 입수, 백립중을 감소시켜 수량을 격감시키지만 단백질 함양에는 영향을 미치지 않았다. 6.수량에 대한 녹병의 영향은 내병성품종에서 22.3%, 이병성품종에서 68.7%의 수양감소가 있었다. The physiological reaction of two soybean (Glycine max (L.) Merrill) cultivars tolerant and susceptible to rust (Phakopsora pachyrhizi Syd.) was studied at the AVRDC in Taiwan, ROC. The rust epidemic on the susceptible cultivar began earlier and progressed more rapidly than on the tolerant cultivar. The defoliation by rust infection increased rapidly after the latter half of pod filling. The reduction of LA! by rust in the susceptible cultivar occurred earlier than in the tolerant cultivar. The differences in the chlorophyll content between the rust-free and rust-infected plants was 2.04% in the tolerant, and 16.43% in the susceptible cultivar. The shoot dry weight increased at each growth stage in the fungicide protected plots, but decreased in the non-fungicide protected plots after the R6 growth stage onward and the tendency to decrease was more severe in the susceptible than in the tolerant cultivar. The pod and seed dry weight of the suscep-tible cultivar in the fungicide-protected plot increased dramatically from the R6 growth stage, but in the non-fungicide plot, there was almost no increase in pod and seed dry weight from R6 growth stage, due to rust. The number of empty pods and imperfect grains were increased by rust infection, but the protein content was not afftected. There were reductions of oil content, seed length, seed width, seed thickness, pod thickness, number of pods and seeds, 100 seed weight, and yield due to rust infection. The yield losses by rust infection were 22.3%in the tolerant and 68.7% in the susceptible cultivar.

For the four times of rapid generation advancement(RGA) of soybean in a year including two times of RGA in the greenhouse during winter, this experiment was conducted to investigate the method of two times of RGA for six months from May to October under different day lengths with natural temperature condition. For this experiment four soybean cultivars, H-25(maturity group, Ⅱ), Ishiharadaizu(Ⅱ), Milyangkong(Ⅲ-Ⅳ), Essex(Ⅴ) were planted on May 1 and August 1 in 1987 in 1/2,000a pots at the Yeongnam Crop Experiment Station(35° 29’ N, 128° 45’ E). And four different day lengths(natural, 12 hour, 10 hour and 8 hour photoperiods) were applied from unifoliate stage to flowering of soybean. The days from planting to flowering(DPF), flowering to maturity(DFM) and planting to maturity(DPM) were shortened effectively at the 10 hours day length at planting on May 1. DFM of Ishiharadaizu was the shortest by 84 days, and it of Essex was the longest by 97 days under 10 hours photoperiod among four cultivars planted on May 1. Also at planting on August 1, DFM of Ishiharadaizu was the shortest by 79 days and it of Milyangkong was the longest by 90 days under 10 hours photoperiod. Under 10 hours day length, the number of grains per plant of four cultivars were ranged from 33 to 59 at planting on May 1, and from 20 to 30 at planting on August 1. These results suggested that two times of generation could be advanced for six months from May 1 to October 31 by applying 10 hours day length from unifoliate to flowering, by harvesting immature soybean seeds before 15 to 20 days of maturity which have germinability over 80 percent.

Background and Objectives: There is a paucity of data regarding the benefit of clopidogrel monotherapy after dual antiplatelet therapy (DAPT) in patients treated with drug-eluting stents (DES). This study compared outcome between clopidogrel versus aspirin as monotherapy after DES for acute myocardial infarction (MI). Methods: From Korea Acute Myocardial Infarction Registry-National Institute of Health database, 1,819 patients treated with DES who were switched to monotherapy with clopidogrel (n=534) or aspirin (n=1,285) after uneventful 12-month DAPT were analyzed. The primary endpoint was net adverse clinical events (NACE), defined as a composite of death from any cause, MI, repeat percutaneous coronary intervention (PCI), stent thrombosis, ischemic stroke, or major bleeding during the period from 12 to 24 months. Results: After adjustment using inverse probability of treatment weighting, patients who received clopidogrel, compared with those treated with aspirin, had a similar incidence of NACE (0.7% and 0.7%; hazard ratio, 1.06; 95% confidence interval, 0.31–3.60; p=0.923). The 2 groups had similar rates of death from any cause (0.1% in each group, p=0.789), MI (0.3% and 0.1%, respectively; p=0.226), repeat PCI (0.1% and 0.3%, respectively; p=0.548), stent thrombosis (0.1% and 0%, respectively; p=0.121), major bleeding (0.2% in each group, p=0.974), and major adverse cardiovascular and cerebrovascular events (0.5% in each group, p=0.924). Conclusions: Monotherapy with clopidogrel, compared to aspirin, after DAPT showed similar clinical outcomes in patients with acute MI treated with DES.

Background: Prognostic implications of BBB in diabetic patients with acute MI have yet to be clarifi ed. Methods: We analyzed 23,724 patients with acute MI from the Korea Acute Myocardial Infarction Registry and the Korea Working Group on Myocardial Infarction Registry. Twelve-month clinical outcome was compared between patients with BBB and those without BBB according to the presence of DM. Results: Patients with left BBB (n = 181) were older, more likely to be men, have hypertension, DM, multi-vessel disease, left ventricular dysfunction, less likely to have chest pain at presentation and receive percutaneous coronary intervention (PCI) and beta blockers. Allcause mortality and the rate of major adverse cardiac events (MACE: all-cause mortality, MI, and repeat revascularization) were higher in patients with left BBB at 1 month and 12 months. Patients with right BBB (n = 494) were older, more likely to be men, have prior stroke, less likely to have chest pain at presentation and PCI. All-cause mortality and MACE were similar at 1 month, but higher in patients with right BBB at 12 months. Diabetics with left BBB, compared to diabetics without left BBB, had higher prevalence of multi-vessel disease (80% vs. 65%, p = 0.024), which was similar in non-diabetics regardless of the presence of left BBB. On multivariate analysis, left BBB was associated with 12-month allcause mortality in diabetics (hazard ratio: 2.6; 95% confi dence interval: 1.25 to 5.25; p = 0.010), but not in non-diabetics, while right BBB was not an independent predictor of death regardless of diabetic status. Conclusions: In patients with acute MI, BBB was associated with worse 12-month clinical outcome. Particularly in diabetics, left BBB was associated with more extensive coronary artery disease and higher mortality.
