통발 구멍의 直徑을 4단계로 만들어 1988年 10月 중에 南部海域에서 釜山水産大學 實習船 402호와 403호로 操業을 하여 어획한 붕장어 Astroconger Myriaster의 全長을 측정하여 붕장어에 대한 張(1987)의 어체제원간 관계식 妥堂性과 플라스틱 통발 구멍의 適正直徑을 알아본 結果를 要約하면 다음과 같다. 1. 魚體諸元間의 關係式 D=0.07L-0.59 은, 통발 구멍의 直徑 D값에 대한 全長 L값 이상으로의 漁獲率이 Pl, P2, P3와 P4 각각 97.4, 94.9, 100.0 96.0%로 매우 妥堂性이 있다. 2. 붕장어 플라스틱 통발 구멍의 適正直徑은 적어도 1.5cm 이상은 되어야 한다. The authors carried out an experimental fishing of Sea eel (Astroconger Myriaster) Pots to find the accuracy of the relationship formula between body dimensions and the optimum diameter of pot hole. The diameter of pot hole was used by an experimental fishing were 0.7, 0.9, 1.0, 1.5, 2.0 cm. The number of pot were 271, 278, 283, 296 respectively. An experimental fishing was performed during october, 1988 in the Southern Sea of Korea. The results obtained can be summarized as follows; 1. The relationship formula between body dimensions was very accurate. 2. Optimum diameter of pot hole must be made 1.5 cm at least.

멸치 總漁獲量의 60%정도를 차지하는 權現網漁業의 漁況과 資源의 適正利用을 위한 방안으로 멸치의 體長, 禁漁期와 자루그물의 코크기 사이의 關係, 最大特積的生産量을 올리기 위한 漁獲努力量의 決定등을 分析·檢討한 結果를 要約하면 다음과 같다. 1. 權現網漁業의 漁獲量은 7-15만톤으로 멸치 생산량의 60% 정도를 차지하며, 97, 98, 99해구에서 權現網漁獲量의 90%를 어획하고 있다. 2. 멸치 산란철의 평균수온분포는 10-20℃였고, 平均?分分布는 33.0-34.4‰였다. 3. 權現網漁業 主魚期의 平均水溫分布는 15-26℃였고, 平均?分分布는 32.0-34.0‰였다. 4. 흉어년과 풍어년의 산란철 주어기 동안의 수온분포는 뚜렷한 차이는 없었다. 5. 權現網으로 漁獲되는 멸치의 加入體長은 1-lOcm인데, 2-6cm가 主를 이루므로 禁魚期를 연장하던지 자루 그물의 코크기를 크게하는 것이 유리 하다. 6. 漁獲努力量과 漁獲量과의 關係式은 Yt=3.07·Xt-1.78×10^-5ㆍXt^2이 되므로, 漁獲努力量 Xt=86,236HP일 때 最大特적積生産量 Yt=132,373M/T를 올릴 수 있다. The authors studied to analyse between fishing conditions and the proper exploitage of resource in Anchovy boat seine. The results obtained can be summarized as follows; 1. The annual catch of Anchovy boat seine varied from 70,000M/T to 150,000M/T, the main fishing grounds of the Anchovy boat seine was in 97,98, 99 marine zone. 2. Distributions of yearly mean sea temperature and salinity in'the spawhing season of Anchovy were respectivly 10-20℃,33.0-33.4‰. during 1961-83. 3. Distributions of yearly mean sea temperature and salinity in the main fishing season of Anchovy boat seine were respectively 15-26℃, 32.0-34.0‰. during 1961-83. 4. The distribution tendency of sea temperature of the spawning season and main fishing season in the year of poor and rich catch was nearly same. 5. The relationship between fishing effort and catch may be expressed as; Yt=3.07Xt-1.78×10^-5Xt^2(r=-0.81) Xt = fishing effort Yt = catch

최충식,채정호,우동원,최영희,함웅,이규항,장미화 대한신경정신의학회 2001 신경정신의학 Vol.40 No.1

연구목적: 정신분열병 환자에서의 재활치료는 개인의 극복 기술과 능력을 향상시키고 재발을 유발시킬 수 있는 스트레스의 부정적인 영향을 중화시킴으로써 질병의 만성화를 막고 사회기능을 호전시킬 수 있기에 점차 그 중요성이 대두되고 있다. 본 연구는 만성 정신분열병 입원 환자에서 재활치료의 하나인 단축형 증상관리 훈련이 정신장애에 대한 자기 인식에 미치는 효능을 알아보기 위하여 시행되었다. 방법: 정신분열병으로 진단받고 입원 중인 환자들에게 재발경고징후를 규명하는 것, 재발경고징후를 관리하는 것, 지속증상을 극복하는 것, 술과 불법 약물을 피하는 것 등으로 구성된 승인-UCLA 사회기술 및 독립적인 생활기술훈련 단위 중 증상관리단위를 기초로 한국실정에 맞게 축약한 증산관리 훈련을 주 1회, 60분씩, 4∼5주간 실시하였고 실시 전후에 전신장애 비인식 평가 척도(Scale to Assess Unawareness ofMental Disorder; 이하 SUMD)로 자신의 정신장애에 대한 인식을 평가하였으며 임상적 전반적 인상(Clinical Global Impression;이하 CGI)로 임상 상태를 조사하였고 각 인구학적 변인들을 조사하였다. 결과: 환자 30명이 훈련을 완수하였으며 이들의 평균 연령은 36.6±7.6세였고 남자가 14명(46.7%), 여자가16명(53.3%)이었다. SUMD 점수는 훈련 전 16.9±4.0점에서 훈련 후 12.9±4.2점으로 유의하게 줄어 정신장애에 대한 자기 인식 정도가 향상되었으며(p<0.01), CGI도 훈련전의 3.7±0.9점에서 훈련 후 2.8±0.8점으로 유의하게 호전되었다(p<0.01). 환자의 연령, 발병시 연령, 유병 기간, 입원 기간, 항정신병약물 사용 용량, 교육 정도, CGI로 평가한 임상 상태등은 정신장애의 자기 인식 정도와는 관련성이 없었다. 결론: 정신분열병 입원 환자에서 단축형 증상관리 훈련은 정신장애에 대한 자기 인식을 증가시킬 수 있는 방법이 될 가능성을 확인하였으며 이 방법이 정신분열병 재활치료의 중요한 요소가 될 수 있음을 알 수 있었다. Objectives : The purpose of this study was to examine whether Symptom Management Module-Korean Brief Version(SMM-B) is effective as a psychosocial treatment of the inpat-ients with chronic schizophrenia. We also questioned which of demographic and clinical characteristics could be predictors of differential treatment response. Methods : The subjects were composed of 30 inpatients with chronic schizophrenia, who were trained with weekly session of SMM-B for 5 weeks. Before and after the training, the level of psychopathology, knowledge about schizophrenia were assessed as dependent variables by using Clinical Global Impression(CGI) and Scale to Assess Unawareness of Mental Disorder(SUMD). Results : Overall, patients showed improvement over the treatment period on psychopath-ology as well as knowledge about psychosis. Total scores of SUMD were changed from 16.9±4.0 before training to 12.9±4.2 after training(p<0.01) and scores of CGI were improved from 3.7±0.9 to 2.8±0.8<p<0.01). Howver age, gender, years of education, age of onset, duration of illness, duration of admission, numbers of psychiatric admission, and clinical status evaluated by CGI were not correlated with unawareness of psychosis. Conclusion : These results suggest that SMM-B could be a reliable method to improve self-aw-areness of psychosis in patients whth chronic schizophrenia and one of important elements in rehabilitation.

거대첨규 콘딜로마로부터 속발된 음경암 1치험예 : A Case Report

김수현,정충식,노준,박도영,장대수 조선대학교 1994 The Medical Journal of Chosun University Vol.19 No.2

The giant condyloma or carcinoma-like condylima is relatively rare. Although the disease is considered clinically mailgant. the possiblity of maligant changes from them are controversial even among the investigators but cannot be entirely overlooked. Most authorists consider that they get the possibility of malignant change. A case of malignancy of the penis which have apparently been transformed from giant condyloma acuminatum of the penis is herein presented with review of literature.

Effect of Tapered Nozzle Hole on Spray Characteristics of High Pressure Diesel Injection

( Jang Sik Kong ),( Choong Sik Bae ) 한국액체미립화학회 2010 한국액체미립화학회 학술강연회 논문집 Vol.2010 No.-

Tapered nozzle hole increases the discharge coefficient and reduces the cavitation in the hole. Non-evaporating diesel sprays from common-rail systems were characterized to investigate the effect of tapered nozzle-hole in diesel injector. Macroscopic spray parameters including penetration and spray angle were analyzed from spray images at constant volume chamber using high speed camera and spark light. Microscopic images of initial spray and spray angle oscillation at near nozzle hole exit were obtained with a long distance microscopic lens. Injection rate shape was measured using the injection rate meter with Bosch tube method. The velocity and particle size of droplets were measured using a phase Doppler anemometer system. It was found from the result of injection rate shape that initial increasing slope of injection velocity from tapered nozzle hole was higher than that of straight nozzle under the same injection pressure. The peak flow velocity from tapered nozzle hole was also higher. At initial stage, spray penetration increased according to injection rate change. As enough time elapsed from start of injection, spray penetration increased according to the square root of time. Spray tip penetration in-creased with tapered nozzle hole because of higher initial injection velocity. And at the vicinity of nozzle hole exit, spray angle decreased with tapered nozzle hole because of strong spray axial momentum. Sauter mean diameter (SMD) at the downstream value with tapered nozzle hole was smaller than that of straight nozzle hole due to higher initial injection and increased air/fuel momentum exchange.

The experiments were carried out to decide the selective fishing gear of the shrimp beam trawl fishery. The model nets were made of General type, Double-level type and Grid type. The model experiments were carried out to test opening efficiency and towing tension. The experimental tanks were the flume tank〔8.0L×2.8W×1.4H (m)〕and the towing tank〔85L×10W×3.5H (m)〕in National Fisheries Research and Development Institute. The full scale experiments were carried out to compare the selectivity of General type net, Double-level type net and Grid type net in the southern sea of korea. The vertical opening (net height) of the model nets can be expressed as a function of the towing velocity as the straight line. The towing tension of the model nets can be expressed as a function of the towing velocity as the parabola. The shrimp catching rates of upper cod end in Boryeong and tongyeong were 78%, 9% respectively, but the rates of lower cod end were 23%, 91% respectively. The number bycatch rates of General type and Grid type were 23%, 11% respectively, and the weight bycatch rates were 34%, 31% respectively. A selective shrimp beam trawl net is Grid type in korea coastal sea.
