본 연구에서는 보다 일반적이고 실제 이동 통신시 통신로 상에서 항상 나타나게 되는 건물과 건물사이에서 생기는 공간 및 그 밖의 건물과 수목 사이에서 발생하는 공간을 aperture로 간주, 구형 및 원형 aperture로 인한 신호 감쇠에 대한 이론식을 유도한다. 현재 우리나라의 차량 이동 통신 시스템에서 사용하고 있는 주파수대(820Hz-880Hz)의 한 주파수인 820MHz를 선정송수신기를 제작하여 실험 데이타를 얻었다. 이러한 결과는 이론치와 잘 일치함을 볼 수 있었다. In this paper a theoretical formula for the signal attenuation by rectangular and circular apertures was drived by assuming that the space between buildings or branches of a tree is a aperture. To obtain experimental data the frequency 820MHz has been selected which is a frequency in the frequency band of mobile communication in our country. The results agreed well with the theoretical values.

In this paper, we classify criticality prediction models into four types according to the input metric forms and the necessity of the past project data. Many prediction models for identifying fault-prone modules using complexity metrics have been suggested. But most of them are VI-SL models that need training data set. Unfortunately very few organizations have their own training data. To solve this problem, we build a new VI-UL model, KSM, based on Kohonen SOM neural networks. We compare and evaluate KSM and a well-known VI-SL model, BPM, considering internal characteristics, utilization cost and accuracy of prediction. As a result, we show that KSM has similar performance with the VI-SL model.

The gu-chang is oriental medical disease name. This study has been carried out to investigate pathogenic factor, pathogenesis, treatment method and medicine of the gu chang by referring to literatures. The results were obtained as follows; 1. Pathogenic factors are pungent taste, stir frying, rich and fatty diet, alchol, disorder of emotion, exogenous pathogen, excessive fatigue and indulgence in sexual activities. 2. Pathogenesis of the gu chang is that the fire heat go up to the mouse. 3. The symptoms are divided into two syndrome. one is sthenia syndrome(實證) - red color and swelling, unendurable pain, strong pulse(脈實), the other is asthenia syndrome(虛症) - pink color, a slight pain, relapse, loose stool, feeble pulse(脈虛). 4. The treatment method is divided into two parts. one is a sthenic syndrome (實證) - clearing strong heat (淸實熱), the other is a asthenic syndrome(虛症) - nourishing yin(滋陰) and clearing deficient heat (淸虛熱), reinforcing the spleen and strengthening middle - JIAO(健脾 補中). 5. The prescription were liang ge san(凉膈散), Ij jhong tang(理中湯) ,xie xim tang(瀉心湯), bu ja li jhong tang, (附子理中湯),liuwei wan(六味元), ba wei wan(八味元), zhuye shigao tang(竹葉石膏湯), si wu tang(四物湯), bu zhong yi gi tang(補中益氣湯) etc.

소프트웨어 개발 초기 단계의 문제점이 개발 후반부 산물의 품질에 심각한 영향을 미치기 때문에 설계 명세를 이용하여 결함경향성이 많은 부분을 예측하는 위험도 예측 모델은 전체 시스템 개발비용을 낮추는 데 중요한 역할을 하고 있으며, 이러한 예측 모델은 결과 산물이 매우 크고 실행 정확성이 요구되는 통신 소프트웨어 같은 실시간 시스템 설계에 더욱 필요하다. 판별분석, 인공신경망, 분류트리 등의 기법들을 이용한 모델들이 제안되었으나 이들은 결과에 대한 원인 분석의 어려움, 낮은 확장성 등의 문제점들을 지니고 있었다. 본 논문에서는 유전자 알고리즘을 이용한 위험도 예측 모델을 제안한다. 여러 내부 특성들 비교와 모의 실험을 통한 예측 정확도 비교를 통해 제안 모델을 타 모델들과 비교하였다. Criticality prediction models that determine whether a design entity is fault-prone or non fault-prone play an important role in reducing system development costs because the problems in early phases largely affect the quality of the late products. Real-time systems such as telecommunication systems are so large that criticality prediction is more important in real-time system design. The current models are based on the technique such as discriminant analysis, neural net and classification trees. These models have some problems with analyzing causes of the prediction results and low extendability. This paper proposes a criticality prediction model with genetic algorithm. This model is implemented and compared by a simulation with the backpropagation neural net model.

1, 3-Di(2-dodecanoylaminoethl)-2, 7-dioxy-1, 3, 6, 8-tetraazacyclodecane[DDTD] and sorbitan monostearate(SMS) were synthesized as a main component for softner. O/W type softner(DSA) was prepared by blending of DSA, SMS, polyoxyethylene(10) castor oil, glyceryl monooleate, and polyoxyethylene(7) stearyl ether. After treatment of DSA to all cotton fabrics, the physical properties such as tear strength, crease recovery, and flexing abrasion resistance were measured. As a result of the measurement, DSA was found to be durable softner with good softness.
