For resonable curriculum modification and development corresponding with training to competent high-level, engineering as educational object of industrial university this research was carried out as following process ; 1. Collection and analysis of present curriculum in civil engineering department of domestic industrial university including the curriculum of foreign industrial university. 2. Organization of advisory committee for insustry school cooperation and visiting insustry and interview. 3. Organization of all Korea Civil Engineering Department chief committe. 4. Result of research through the questionnaire for all Korea representative industry and academic could be summarized as follows : 1) Wide contact between college education and industry field should be strengthened, and field experiment education was strengthened to consider of ability, and construction management was edited compulsory major. 2) For the adapting trend of variety and subdivision of construction skill EDPS education was edited compulsory 3) The curriculum was endeavoured to fundamental science. 4) The curriculum enlarged the range of the optional subject which is able to manage the flexible curriculum for characterization of each local industrial university and endeavoured consideration of field adapting ability by classifing the civil design into Construction design and integration, Hydraulic design and integration, Earth design and integration. 5) The curriculum of academic theories and experiments were unificated into single subject for the purpose of flexible management 6) The curriculum was edited in the ration which is 20 to 80 between liberal and majoring arts in presentation on the basis of all accounts of opinion from the academic and field worker, and emphasized the importance of language education editing industrial English conversation because of demand of much ability along with foreign advance of construction technique. 7) The curriculum was emphasized in the necessity of the field experimental trained based on the information by all opinion. By operationg this curriculum, it is expected that the relationship between industry and academic will be efficiently considered.

상호활성화모형과 다중해상도경로에 기반한 문자인식 시스템

김상기,방승양,김대진 한국뇌학회 2001 한국뇌학회지 Vol.1 No.2

한국어의 글자를 인식하기 위한 새로운 계산모형을 제시한다. 제안된 모형은 상호활성화모형에 기반을 두고 있으나 모든 입력이 규격화된 형태라는 가정을 배제시켜 실제적인 문자인식에 적용할 수 있도록 하였다. 또한 성능향상을 위하여 계산모형에 다중해상도경로 학설을 적용하였다. 제안된 모형을 구현하고 이를 실제 자료에 적용하여 그 결과를 살펴보았다. 모의실험의 결과는 모형이 실용적인 목적으로도 가치가 있음을 보여주며 또한 상호활성화모형과 다중해상도경로가 계산모형의 성능 향상에 큰 역할을 함을 보여주었다. A computational model to recognize Korean characters is presneted. The model is based on IAM but improves the input processing part. We excluded the assumption that all the characters are of a standard templete. Also we incorporated the multi-resolution channel theory so that we can improve the performance. We simulated the model and tried it to real data. The simulation results show that the model has a practical significance and that IAM and the multi-resolution channels actually improve the performance.

The present study investigates the effect of injection angle of water mist on fire suppression characteristics by numerical simulation. In order to validate the temperature field by numerical simulation, the predicted results are compared with experimental data. It shows that the temperature difference between measurements and predictions are within 10℃. Numerical simulations of fire suppression are performed for 4 different injection angle(60°, 90°, 120° and 180°). The global mean temperature over the fire compartment decrease with increasing of spray angle. The result shows that the heat transfer between droplets and gas phase are enhanced with the increasing of spray angle. Near the fire source, temperature field by the wide spray angle is slightly higher than that of narrow injection angle because of direct cooling of fire source.

울산지역 췌담관질환 환자의 간흡충 감염 실태 : 담즙검사를 기준으로 based on bile examination

이기영,주광로,김현수,신수진,이효섭,윤태권,추연익,박종호,신정우,방성조,김도하,박능화 대한내과학회 2004 대한내과학회지 Vol.66 No.5

목적 : 간흡충증의 진단은 분변 또는 담즙에서 간흡충의 성충 또는 충란을 발견하는 것이다. 담즙을 통한 간흡충 진단은 간흡충이 존재하는 담관에서 검체를 직접 채취한다는 장점과 이 검체가 분변이나 체액에 의해 희석되지 않으며, 특히 담관 폐색이 있을 경우 담즙배설 장애로 인한 분변검사의 위음성을 줄일 수 있는 가장 정확한 간흡충의 기생충학적 검사로 생각된다. 이에 저자들은 울산지역 췌담관 질환 환자에서 담즙검사를 기준으로 한 간흡충의 감염 실태를 알아보고자 하였다. 방법 : 내시경적 또는 경피경간 담관배액술을 통해 담즙을 채취하여 간흡충 충란 유무를 확인한 309명의 췌담과 질환 환자에서 간흡충 감염 실태를 조사하였다. 결과 : 대상 환자 전체의 충란 양성률은 27.5%였고, 남녀의 충란 양성률은 각각 35.%와 17.6%로 남자에서 더 높았다. 연령별 충란 양성률은 30대 20.0%, 40대 26.7%, 50대 24.2%, 60대 29.9%, 70대 36.2% 그리고 80대 이상이 16.7%로 연량에 따른 통계적 차이는 없었다. 질병별 충란 양성률은 담관암 32.65, 담낭암 38.5%, 파터팽대부암 11.1%, 췌장암 24.0%, 담석질환 26.4%,간흡충담관염 61.5% 그리고 이외 질환이 12.5%로 간흡충 담관염ㅇ르 제외한 질병간 의미있는 차이는 없었으며 결석의 위치, 간흡충 연관질환인지 아닌지가 충란 양성률에 영향을 미치지 못했다. 담관 조영술을 포함한 방사선 검사에서 정상 담관을 보인 환자에서 충란 양성률은 17.0%였다. 결론 : 본 연구 결과 울산지역 췌담관 질환 환자에서 간흡충 감염률은 연령, 성별, 질병의 종류에 관계없이 전반적으로 매우 높았다. 따라서 이러한 자료를 근거로 생각해 볼 때 우리 나라가 아직도 심각한 간흡충 감염의 유행지임을 추론할 수 있겠다. Background : Bile examination is believed to be the most precise method for detecting Clonorchis sinesis (CS) eggs. We carried out bile examination to evaluate infestation state of CS in patients with pancreatobiliary diseases in Ulsan, known as an endemic area of CS infestation. Methods : We examined CS eggs in bile in three hundreds and nine patients with pancreatobiliary diseases. The bile was obtained from endoscopic nasobiliary or percutaneous transhepatic biliary drainage tubes. Results : The overall egg positive rate was 27.5% (35.3% in male,17.6% in female). The egg positive rate was not significantly different according to the age group: 20.0% in thirties, 26.7% in forties, 24.2% in fifties, 29.9% in sixties, 36.2% in seventies and 16.7% in eighties or more. The egg positive rate according to the disease, except CS cholangitis, was not also statistically different: 32.6% in bile duct cancer, 38.5% in gallbladder cancer, 11.1% in ampulla of Vater cancer, 24.0% in pancreatic cancer, 26.4% in gallstone diseases and 12.5% in the reminder. The location of gallstone and whether CS related diseases or CS unrelated diseases did not affect the egg positive rates. The egg positive rate in patients with normal radiological findings including cholangiography was 17.0%. Conclusion : This result shows that regardless of age, sex and sorts of diseases, the infestation rate of CS was very high. On the basis of our results, it if therefore presumes that clonorchiasis is still endemic disease in Korea.

The present study investigates the spray characteristics of water mist nozzle with mid-low pressure for fire suppression. The examined nozzle types are swirl nozzle. The result shows that K factor of water mist nozzle is much smaller than those of general sprinkler. Spray angle of spiral nozzle is largest and more than 150˚. SND(Sauter Mean Diameter) of water mist nozzles is ranged between 100 and 200㎛ through measuring by image processing method. The spray pattern of spiral nozzle represent that water flux of first stream is 2 times larger than that of second stream. This study will contribute better understandings of the water-mist spray characteristics and useful data for developing the water-mist nozzles.
