Intestinal duplication is a rare congenital anomaly. The diagnostic approach is difficult because of the differences in its location and clinical presentation. To evaluate the diagnostic as well as the therapeutic approaches in children, the medical records of 20 patients with intestinal duplications which had been operated upon from July 1980 to October 2002 were analyzed, retrospectively. The range of age was from 1 day to 11 years. The variables, such as age, sex, clinical presentation, diagnostic method, localization, anatomic type, treatment, complication, and combined anomalies were analyzed. Most of the cases were presented as incidental finding. The majority of the duplications except hindgut were cystic type. Treatment included segmental intestinal resection, excision of the lesion without intestinal resection, and septotomy. Seventy-five percent of the patients were detected before 1 year of age. The anatomic type of the lesion was closely related with its location. The cases of hindgut were almost always tubular type except 1 case. Clinical presentation was related to age, location, and anatomic type. There were no specific diagnostic methods. Perfect localization and application of appropriate operation are the most important requirements for successful treatment.

This study investigates interior and exterior environments and arrangement forms of school buildings from elementary to high school which were recently built in Daegu since the 7th Educational Curriculum. In addition, this study analyses how outside noise affects inside environment of schools. This study found that the noise level criteria of school facilities(such as exterior learning sites and outer walls of school buildings) adjacent to street of one side satisfiedly corresponded to the level and criteria, 65dB(A), of school health law. However, the noise level and vibration criteria of school facilities adjacent to street of two sides did not satisfiedly corresponded to the level or criteria, 65dB(A). In case of classrooms, the inner noise of educational facilities with windows closed and also close to both the street of one side and of two sides satisfiedly corresponded to the level or criteria. 55dB(A), of school health law. In spring and tall, the windows are more open them usual for ventilation, and leaving windows open can lead to noise from outside. Thus, it is urgent to prepare for this situation.

김태우,Kim, Tae-Woo 한국정보처리학회 2000 정보처리논문지 Vol.7 No.2
본 논문에서는 MR 영상의 3차원 가시화 및 분석을 위한 단일 채널 MR 영상의 자동 뇌영역 분할 방법을 제안한다. 이 방법은 4단계의 2차원 및 3차원 처리에 의하여 뇌윤곽을 찾아낸다. 1,2단계에서는 곡선 적합을 이용한 자동 문턱치화에 의하여 머리마스크와 초기 뇌마스크를 생성한다. 3단계에서 입방보간으로 초기 뇌마스크의 3차원 볼륨을 생성하여 형태학적 연산, 연결부위 레이블링에 의하여 중기 뇌마스크를 생성한다. 최종적으로 곡선 적합에 의한 자동 문턱치화를 이용하여 뇌마스크를 정련한다. 제안한 알고리즘은 영상의 슬라이스 방향을 고려할 필요가 없고 영상이 뇌 전체를 포함하지 않아도 되며, T1, T2, PD, SPGR등 다양한 종류의 MR 영상의 자동적인 뇌영역의 분할에 유용하다. 실험에서 20세트 MR 영상에 대하여 수동분할을 기준으로 0.97 이상의 유지도를 보였다. In this paper, a novel technique is presented for automatic brain region segmentation in single channel MR image data sets for 3D visualization and analysis. The method detects brain contours in 2D and 3D processing of four steps. The first and the second make a head mask and an initial brain mask by automatic thresholding using a curve fitting technique. The stage 3 reconstructs 3D volume of the initial brain mask by cubic interpolation and generates an intermediate brain mask using morphological operation and labeling of connected components. In the final step, the brain mask is refined by automatic thresholding using curve fitting. This algorithm is useful for fully automatic brain region segmentation of T1-weighted, T2-weighted, PD-weighted, SPGR MRI data sets without considering slice direction and covering a whole volume of a brain. In the experiments, the algorithm was applied to 20 sets of MR images and showed over 0.97 in comparison with manual drawing in similarity index.

In case of school buildings, energy consumption has been noticeably on the increase, along with the changes in outdoor temperature triggered by the improvement in national economic development and educational environments. Research on the characteristics of energy consumption in school buildings influenced by the changes in outdoor temperature is considered very significant in social aspects in that it will be fundamental to the suggestion of the alternatives, such as saving energy consumption in construction buildings and control of emitting carbon dioxide. In this regard, this study examined sensitivity to temperature of power consumption in school buildings, based on the changes of outdoor temperature for the past five years in the target buildings of elementary, middle and high schools and the amount of energy consumption. From the results, it has been believed that this study was very significant in terms of figuring out a quantitative, optimum level of energy consumption, maintenance of pleasant environments and functions, and the necessity of effective energy use and management in school buildings.

Signals in an underwater channel get distorted by multipath propagation. In this paper, pre-coding method is suggested which helps comprehending the signals with minimum equalization. The signals are transformed based on the knowledge of the impulse response of the channel. Proposed pre-coding method is tested by simulations based on the ray theory and through water tank experiments. In weak multipath environment, in case of an SNR of about 20 dB, BER is $10^{-3}{\sim}10^{-4}$, while in strong multipath environment, similar BER is achieved with SNR of about 30 dB. In order for the pre-coding method to be used for underwater vehicles, channel prediction method utilizing the waveguide invariant is suggested and tested. 수중 채널에서의 음파를 사용한 신호는 다중 전달 경로 현상에 의해 왜곡된다. 본 논문에서는 채널의 임펄스 응답을 바탕으로 신호를 미리 왜곡시켜 수신기에 도착했을 때 최소한의 등화만으로 신호를 받을 수 있는 선 처리 기법을 제안하였다. 그리고 음선 이론 기반 시뮬레이션과 수조 실험을 통해 제안한 기법의 성능을 검토하였다. 다중 전달 경로 현상이 약할 경우, SNR이 약 20 dB 일 때 BER이 $10^{-3}{\sim}10^{-4}$의 성능을 보였고 다중 전달 경로 현상이 심한 환경에서 SNR이 약 30 dB 일때 유사한 BER 성능을 보였다. 제안한 기법을 수중 운동체의 통신에 사용가능하도록 송수신기의 위치 변화에 따른 채널예측 기법을 제안하였고 그 성능을 검토하였다.

Vascular dementia is a very frequent form of dementia. Debates over classification and diagnostic criteria, and controversy over identifiable treatment targets will continue until distinct pathophysiological mechanism of vascular dementia is found. Clinical diagnostic criteria are sufficiently strong to be useful for clinical trials, but need further refinement. Cognitive changes in vascular dementia are more variable than other disorders, and are dependent on the vascular pathology. Accurate diagnosis of vascular dementia is known to need the presence of reliable cerebrovascular disease on brain imaging. Although it seems obvious that cerebrovascular disease causes pathological damage and impaired cognition, it is very difficult to find the accurate contribution of cerebrovascular pathology to cognitive decline. Most studies have shown a small but significant benefit of cholinesterase inhibitors on cognition, the significance of this effect has been slight and benefits on global functioning, activities of daily living, and behaviour have not been consistently reported. Management of vascular dementia should focus on identifying and managing vascular risk factors.
