최근 과학기술의 발달로 인공위성을 이용한 정밀 위치 측정과 정밀 시각 측정에 대한 수용이 날로 증가하고 있다. 특히 정밀 시각 측정은 차세대 이동통신 기술인 CDMA의 핵심 기술로 매우 중요하게 인식되어 왔다. 현재 정밀 시각을 측정하기 위해서는 GPS위성 수신기 개발이 시급한 실정이다. 본 논문은 GPS 동기 신호 수신기를 개발하기 위한 TIC 및 A/R 회로를 개발하는 것으로서 GPS 위성의 1pps와 수신신호에 의한 1pps의 차를 ±1㎲이내로 좁히는 알고리즘 및 Hardware를 개발한 것이다.

The purpose of this study was to investigate multiple body-image and clothing-benefit sought according to body-cathexis. The questionnaire was administered to 458 female college students in Daegu and Kyungpook. The results were obtained as follows. Most respondents were dissatisfied with their body, especially with lower parts and weight. Among three factors of multiple body-image, degree of appearance-conscious was high, but degree of weight control and physical attractiveness were evaluated low. According to body-cathexis, differences were found in degree of weight control and physical attractiveness between groups. Respondents sought practical use of one's clothing most and comfort, figure flaws compensation, in turn. According to body-cathexis, differences were found in 4 factors of clothing-benefit sought, those were figure flaws compensation, sex appeal, individuality, practical use between groups. Between the factors of multiple body-image and the factors of clothing-benefit sought, positive or negative correlations were found, so it indicated that one's body-image was effected on clothing-benefit sought.

In this paper, a theoretical optimization approach is presented in order to consider natural frequencies for vibration transmitted to the fuselage. Also, this paper describes methods for reduction of structural vibration by the optimal placement of masses for formal mathematical optomization techniques. An optimization procedure is developed which employs the tuning masses and corresponding locations as design valiables which are systematically changed to achieve low values of shear without a large mass penalty. Three optimazation strategies are developed and tested. The first is based on minimizing the modal shaping parameter which indirectly reduce the modal shear amplitudes corresponding to each harmonic of airload. The second strategy reduces these amplitudes directly and the third strategy reduces the shear as a function of time during a revolution of the blade.

1. 금호강물에 대한 상대독성과 수온, 전기전도도의 경우 달서천 내부, 금호강과 달서천의 합류점 하부, 합류점 상부 순으로 값의 크기를 보였고 pH의 경우 역순을 보이므로 달서천이 금호강과 달서천 합류점 하부에 영향을 주는 것으로 사료된다. 2. 금호강 하천수에 대한 Microtox 독성값과 온도, pH, 전기전도도의 상관성은 없었으므로 기존의 일반적인 몇 가지 수질 인자로는 독성변화 및 수준을 판단할 수 없다고 사료된다. 3. 36시간 연속 모니터링을 통해 짧은 시간에도 독성값이 달라지는 것으로 보아 수질의 독성 수준이나 오염 수준을 판단하기 위해서는 연속적인 독성 조사 및 분석이 필요하다고 사료된다. 4. 하천수에 대한 연속 모니터링만으로는 하천 생태 위해도를 평가하기는 어렵다. 따라서, 하천 퇴적물에 대한 특성을 병행하여 조사 분석하는 것이 유해화학물질에 의한 하천 오염을 평가하는 방법이 된다고 사료된다. The main point source of pollution of the Keumho river in Taegu, Korea, stems from waste from the areas of industrial complexes. Although it is widely accepted that pollutants in waste water negatively effects general water quality, it is difficult to evaluate the effluent effect because of varying conditions in ambient water and inconclusive knowledge of causative pollutants. To analyze the water in relation to the industrial effluent in the area, pH, temperature, conductivity, and Microtox toxicity of various river samples were measured. Water samples were collected every 2 hours for 36 hours from Keumho river and Dalseo stream. Data from continuous monitoring for 36 hours showed that effluent in Keumho river originated from Dalseo stream, which is near adjacent to industrial complexes. Change in toxicity and other factors tested during the 36 hours indicated that continuous monitoring was necessary for a satisfactory effluent toxicity test. Furthermore, in addition to water quality monitoring, it was concluded that sediment toxicity also needed to evaluate effluent effects.

家族性 정신분열병과 非家族性 정신분열병과의 比較硏究

Since Kraerelin described dementia preaecox, Schizophrenia has been widely considered to be a heterogenous syndrome. Various approaches have been taken in attempting to subdivide this disorder into more homogenous groups. In addition, it also has considered that genetic factor may contribute to schizophrenia predisposition and schizophrenia may be genetically heterogenous. The existence of a characteristic that expresses a genetic predisposition to schizophrenia would be helpful in defining a genetically more homogenous group. So, this study was performed to evaluate assumptions that schizophrenia could be differentiated on the basis of family history. We compared two groups of patients distinguished by the presence or absence of family history. each groups included 34 schizophrenic patients matched by age and sex. these two groups of patients were evaluated on the aspect of psychopathology, neruomotor function abnormality and pathologic reflex. The results are as follows : 1) There was no significant difference in age of onset, duration of illness, frequency of hospitalization and dosage of drug detween two groups. 2) At the time of admission, there was no significant difference in the psychopathology between two groups. 3) As for the present psychopathology, most patients had remitted from active psychotic symptoms, patiens with family history had significantly more negative symptoms than those without family history. and patients with family history showed singificantly more increasement in negative symptoms from the time of admission to the present than those without family history. 4) We divided the schizophrenia into three subtypes : postive, negative and mixed schizophrenia. At the time of admission there was no significant difference in the rate of these three subtypes between two groups but at present, the proportion of negative schizophrenic patients were increased in the group of patients with family history and that of mixed schizophrenic patients were increased in the guoup of patients without family history. 5) The total score of neuromotor function test were not significantly different between two groups. In the individual test the group of patients with family history showed significantly more abnormal patients in the heel to tap test, and significantly slower speed in the successive finger opposition and heel to tap test. 6) There was no significant difference in the pathologic reflex between two groups. 7) Among patients without family history, there was signiticant correlation berween negative symptoms and neuromotor function abnormality.
