저자들은 1994년 1월 1일부터 1995년 6월 31일까지 가톨릭대학교 의과대학 의정부성모병원 정신과에 입원했던 환자들 중세서 공격행동을 보인 환자(공격군) 72명과 공격행동이 없었던 환자(비공격군) 215명의 임상적 특성에 관한 조사를 하여 다음과 같은 결과를 얻었다. 1) 공격행동을 보인 환자는 72명으로 전체 조사 환자의 25.1%이었다. 2) 성별, 연령, 종교, 결혼 상태와 정신과 질환의 가족력 등에 따른 공격행동의 발생비율의 차이는 유의하지 않았다. 3) 교육 정도와 직업에 따른 공격군의 비육에 유의한 차이가 있었다(p<.05). 4) 진단별로는 공격군에서 조증, 기질성 정신장애, 정신분열증의 빈도가 높았으나 진단에 따른 의미 있는 차이는 없었다. 5) 공격행동의 기왕력은 공격군에서 더 많았고 비공격군과 비교시 의미 있는 차이를 보였으며(p<.001), 입원 형태는 공격군에서 타의 입원의 빈도가 유의하게 높았다(p<.005). 7) 입원시 정신병리는 초조-흥분과 적대감-의심에서 공격군의 빈도가 높았으며 정신병리에 따른 의미 있는 차이를 보였다(p<.001). 8) 총 재원 일수는 공격군에서 평균 59.3일이었고 비공격군이 평균 38.4일로 유의한 차이를 보였다(p<.001). 9) 공격행동의 유형은 말로한 경우가 가장 많았고 물건을 대상으로한 행동, 타인을 대상으로 하는 행동의 순으로 나타났다. 10) 공격행동 직전 행동 특징은 활동증가, 시끄러움, 욕설, 분노, 적대적이었던 경우가 가장 많았다. 11) 공격행동은 정오에서 오후 6시 사이, 휴식시간에 가장 많이 나타났다. 12) 입원 후 1주일 이내에 공격행동의 62.3%가 나타났다. 13) 총공격 점수에 의미 있게 영향을 주었던 변인들로는 종교(p<.05), 교육 정도(p<.05), 직업(p<.05), 입원형태(p<.005), 진단(p<.001), 입원시 정신 병리(p<.001), 공격행동의 기왕력(p<.001) 등으로 나타났다. To evaluate the characteristics of violent behavior of psychiatric inpatients the authors reviewed clinical records of psychiatric patients who had admitted at UiJong Bu St. Mary's Hospital from January 1994 to June 1995. We divided the 287 subjects into violent and nonviolent group according to the presence of violent behaviors in psychiatric ward. We assessed demographic variables, clinical characteristics and violent behaviors using Overt Aggression Scale and compared these variables of violent group with nonviolent group. The results were as follows : 1) The number of violent patients was 72(25.1% of the total). 2) In terms of demographic variables, the differences between two groups in education and occupation were significant(p<.05). 3) In psychiatric diagnoses, violent group were more likely to have mania, schizophrenia and organic mental disorder in sequence but there were no differences between violent and nonviolent group. 4) The history of violent behavior was greater in violent group(p<.001) and the mode of admission was significantly different between two groups(p<.005). 5) In cluster of psychopathology on admission, more frequently found clusters of psychopathology in violent group were agitation-excitement and hostile- suspiciousness and there were significant differences between two groups(p<.001). 6) The length of stay in violent group(59.3 days)was significantly longer than nonviolent group(38.4 days)(p<.001). 7) The types of violent behavior were verbal aggression, physical aggression against objects and physical aggression against other people in frequency sequence. 8) The most frequent type of behavioral clue before violent behavior was hyperactive, loud, verbally abusive, angry, hostile(68.1%). 9) Most of violent behaviors were presented between midday and 6 pm. in resting time. 10) 62.3% of total violent behaviors were occurred within first week following admission. 11) The variables which showed significant effects on total aggression score were religion, educational status, occupation, mode of admission, psychiatric diagnosis, psychopathology on admission and history of violent behavior before admission. In summary, these results showed similar trends compared to previous studies on characteristics of psychiatric inpatients. And we found that more important predictors of violent behavior in practice were likely to be history of violent behavior, psychopathology on admission and behavioral cue before violent behavior.

A rainfall distribution is very complicate owing to topographic influence in Korea. Hence, the variations in the distribution of monthly rainfall are required precise analysis in order to predict a flood control and to secure a sufficient capacity of water. In this study, time series of 32 rain gage stations over Gyeongnam area are examined for a 36-year secular period(1963-2000) and the extent and nature of changes, such as fluctuations, trend and persistence, are investigated. The trend analysis of regional rainfall practised a tendency towards annual rainfall and seasonal rainfall totals in all regions divided into two climatologically homogeneous regions by cluster analysis for annual rainfall series ; namely, Region Ⅰ(gyeongnam's inland area), Region Ⅱ(western mountain & southern coastal area), the periodicity is examined by the power spectrum analysis.

In the rainfall-runoff simulation, it is crucial problem to extract the hydrologic topographical factors that are used as the model input parameters. Those factors are drawn out from DEM(Digit a1 Elevation Model) along with GIS(Geographic Information System) techniques represent a wide range of topographical informations. GIS is employed to estimate the parameters and examine application. Also, the results from different GIS data and analysis methods are examined. In the study, spatial data are calculated using WMS(Watershed Modeling System) v.6.1, which is hydrologic analysis software coupled with GIS, and flood analysis is accomplished by HEC-1 included in WMS, and applied to Dukchon River basin. To calculate the effective rainfall CN values of NRCS are used. Clark, Snyder and NRCS methods are selected to derive unit hydrograph respectively. In addition, the characteristics of runoff responses according to the selection of GIS spatial data for NRCS CN, TIN or Grid used to extract hydrologic topographical informations. and the number of partitioning sub-basin are investigated.

The computation of the water wave forces on offshore structures is one of the primary tasks in the design of the structures. It is also one of the most difficult tasks since it involves the complexity of the interaction of waves with the structures. The Morison equation assumes the wave force to be composed of inertia and drag forces linearly added together. The purpose of this paper is to investigate the wave forces acting on the cylinderical piles. Author set up a cylinderical piles model into 2 dimensional regular wave tank with vaned wave height, water depth, and wave period, and observed wave forced. In practice the wave forces depending on wave height, water depth, and wave period were predicted through the experimental model test. It is presented a good tool to predict qualitatively the wave forces acting on the cyinderical piles.

This paper compares error values of interpolation methods that are used in resampling process before the vibration signal analysis by the change of the motor sped. The motor speed is measured by the tachometer. Tachometer produces one pulse per rotation. We determined resampling time by angle interpolation. To estimate the sample values, we used various interpolation technique. This paper estimated the discrete signal through the linear, quaratic, and cubic interpolation. We proposed the optimum interpolration method by comparing MSE(Mean Squre Error) and calculation amount.

The analysis of water level which is changed because of the construction of bridges, flood river reservation and structures etc is important factor, researching for flood plain in urbanland. In this study, the construction of flood river reservation as multiple-purpose space is planned and water level is predicted for designed discharge in the region. Also, for Nam-river Dam discharge at drier, the rating curves of water level-discharge in upstream-sections of rubber dam are prediced due to the discharge and the optimum height of rubber dam is determinated.

The calmness inside a harbor plays an important role in the appropriate disposition of harbor structures. However, it is not easy to get the accurate computational results because it is affected by many factors concerning with the wave transformation. Recently, numerical model tests which are more economic and rapid than hydraulic model experiments, are carried out for the purpose of analyzing wave height distribution in harbors. This paper presents the numerical model which is able to calculate wave height inside a harbor. It is based upon the time-dependent mild slope equation involving wave refraction, diffraction, shoaling effect and reflection. In particular, the arbitrary reflectivity is used at the boundary in order to simulate the real harbor reflection condition. The proposed numerical model is applied to Samcheon port in order to investigated harbor calmness.

Liquid wastes containing uranium ions in high concentration of chemical salts havebeen treated by electrosorption on a activated carbon fibers(ACFs) electrode. Effectiveuranium (VI) removal is accomplished when the potential is -0.5V(vs. Ag/AgCl) ormore negative. For a feed concentration of 100mg/1, the concentration of U(VI) in thecell effluent is reduced to less than 1mg/1, and electrosorption capacity over 500mg/uranium/gACF is reached. The adsorbed uranium can be desorbed up to 99%for 20h by passing a 1.9N NaCl solution at pH 3 through the cell and applying a potential of +1.2V. The amount of desorbed uranium increased as the solution pHwas lowered and the applied potential increased.
