In this paper, handwritten basic Hangout recognized by using the modified hough transform (MHT) and neural network, in order to reduce misrecognition due to the variation of input patterns according to writers. In order to recognize basic hangout which is consisted of tile 14 single consonants and the 10single vowels, input data of neural network is extracted by coding the location of each stroke which is detected by the MHT. Real time recognition of basic Hangeul can be realized in personal computer by using input data which is compressed to 8 feature value by MHT.

Eisenmenger's syndrome includes any condition in which communication between the pulmonary and systemic circulation gives rise to pulmonary vascular disease causing a right to left shunt with peripheral cyanosis, It can occur with complex congenital cardiac malformations, such as septal defect and patent ductus arteriosus. We report a case of a 58-year-old woman with an emergency operation for peritonitis due to appendiceal perforation and Eisenmenger's syndrome secondary to large ventricular septal defect. We carefully performed balanced anesthesia with air-O₂-desflurane-remifentanil. She was transferred to the intensive care unit in intubated state postoperatively and discharged two weeks later without any complications.

This purpose of the study was to examine the effect of internal-external control and sex-role identities on their career maturity of elementary school children. The subjects in this study were 200 selected six graders who included 100 children from an elementary school in the city of Geoje and 100 from an elementary school in Goseong-gun, South Kyongsang province. The findings of this study could be described as below: First, In regard to the gender-based career maturity discrepancies, gender made no difference to their career choice and career attitude. Second, as a result of investigating whether the career maturity was affected by the internal-external control, the internal-control group was better at total career capability and total career maturity as well. Third, as a result of examining whether the career maturity was influenced by the sex-role identities, the children whose sex-role identities were undifferentiated or androgynous were more dependent than the others. The findings of this study suggest that in order to enhance the career maturity of elementary school children, gender characteristics should be taken into account in developing career-education programs. In addition, there should be a variety of efforts to help children cultivate internal control and androgynous identities.

본 연구에서 한국 토양에서 분리된 lovastatin 생산 균주인 Aspergillus sp. ISR 균주를 이용하여 여러 배지 조성 성분이 lovastatin의 생산에 미치는 영향을 관찰하였다. 탄소원으로는 lactose보다 glycerol 5%가 가장 효과적이었으며 질소원과 인산염의 경우는 기본 RPM배지 조성과 농도에서 보다 효과적인 것을 발견하지 못하였다. 복합영양원으로 rapeseed meal 보다는 대두박이 보다 효과적이어서 저렴한 배지원으로 사용이 가능할 것으로 사료된다. 최종적으로 최적화된 배지를 사용하여 52 mg·L^(-1)의 lovastatin을 생산할 수 있었고 이는 기존의 RPM 배지보다 수율이 4.5배 증가한 것이다. 좀 더 효과적인 lovastatin의 생산을 위하여 회분식 발효에 대한 연구와 분자유전학적인 연구를 통한 고생산 균주의 제조에 대한 연구가 진행중이다. Effects of various nutritional components on the production of lovastatin were investigated in the Aspergillus sp. ISR. Among various carbon (C) sources, glycerol was determined to be the most effective C source at the concentration of 5% (v/v). In case of nitrogen sources, 0.2% (w/v) KNO_(3) efficiently induced the lovastatin production in Aspergillus sp. ISR. Interestingly, the addition of soybean meal into the production medium enhanced the lovastatin production compared to the rapeseed meal. Conclusively, Aspergillus sp. ISR produced 52 mg·L^(-1) of lovastatin in the optimized medium containing 5% (v/v) glycerol, 0.2% (w/v) KNO_(3), 0.3% (w/v) KH_(2)PO_(4), and 0.3% (w/v) soybean meal, which was 4.5 times higher than the amount produced using the standard RPM (rapeseedmeal production medium).

This paper is on the study of strength evaluation for the frame joint made from reinforced concrete column and steel beam(RCS system joints). Especially for those categorized as through beam type, the accuracy of the existing design equations proposed in the inside and outside of the country was studied in detail with shear key such as face bearing plate(FBP), Extended FBP, vertical joint reinforcement. It was shown that strength evaluation equations proposed in James K. Wight provided the most accurate and consistent strength estimates. Some design equations proposed by Japanese often underrated the joint strength for specific joint details.

통신망이 다양화되고 이질화됨에 따라 망을 효과적으로 관리하기 위한 TMN(Telecommunication Management Network)개념이 등장하게 되었고, 관리 대상이 실자원이나 시스템, 소프트웨어 등에 국한 된게 아니라 서비스 영역으로 확대됨에 따라 이 서비스 영역의 관리가 필요하게 되었다. 따라서 본 논문에서는 통합망의 성능과 서비스 관리를 위한 정보 모델을 설계 하기위해 기본적인 TMN 구조와 성능관리, QoS관리를 분석하였다. 그리고 객체지향적인 개념이 적용된 TMN 정보구조 중 관리자/대행자 구조에서 관리정보의 전달 수단인 MO(Managed Object)를 정의하고, MO 클래스들을 GDMO에 따라 표현하였으며, 정의된 MO에 따라 상속트리 및 포함트리를 설계 하였고, E-R 도표를 통해 정의된 객체 클래스들의 관계를 명시하였다.
Determination of failure initiation stress and failure grade using Acoustic emission

The excavation of rock structures in hard rock involves three safety issues: structural failure such as wedge-type failures, brittle failures such as slabbing and spalling, and a combination of these two. Especially at highly stressed levels, the failure process of rock structures are mainly affected and eventually dominated by stress-induced fractures growing preferentially parallel to the excavation boundary. This brittle failure is usually occurred within very small displacement or strain, and thus it is not easy to determine the precursor and initiation stress level of failure in displacement detection method. To overcome this problem, some researchers have tried to adopt the acoustic emission (AE) detection. This study carried out physical model experiments and determined brittle failure initiation stress and failure grade, which are the two important characteristics of brittle failure. Failure initiation stress and failure grade are determined using AE detection as well as visual observation. And the locations of failure were detected in real time by the AE source location. This study showed that AE detection method could be usefully applied to determine the brittle failure initiation.
