일반적으로 사행하천의 만곡부에서는 홍수시 월류의 위험성이 높을 뿐만 아니라, 국부적으로 집중되는 흐름분포는 제방의 안정성을 위협한다. 따라서 본 연구는 두 개의 다른 실험수로에 대한 CCHE2D모형의 적용성 검토와 급변만곡의 형태를 갖는 자연하천의 흐름특성분석을 수행하는데 그 목적이 있다. 모의결과 실험에 대한 수위의 백분율 오차는 4.9%이내였으며, 실측치와 근사한 유속분포를 보였다. 실험수로를 통하여 보정된 모형을 이용하여 용담댐 하류 대유리에 위치한 만곡부를 대상으로 흐름특성 분석을 수행하였다. 모의결과는 만곡부의 지형에 의한 영향을 고려하지 못하는 HEC-RAS모형에 비하여 상류부에서 수위가 1.5 m 정도 높게 나타났다. 그러나 모의결과를 기존의 경험식과 비교한 결과 CCHE2D모형이 편수위 모의에 적합함을 알 수 있었으며, 자연하천의 홍수위와 유속산정에도 적합함을 확인할 수 있었다. In general, curved bends raises a risk of overtopping due to floods and also threatens a bank safety due to a local flow concentration. This study aims to test the applicability of CCHE2D model for experimental flumes with two different types of bends and then investigate flow characteristics in the sharply-curved bend of a natural channel. The results demonstrated that the percent error of water level was within 4.9% for experimental flume applications and the simulated spatial distribution of velocity matched the observed results very closely. The calibrated model based on the experimental flumes was also applied to analyze the flow characteristics in natural channel bends of the Daeyu reach, located in a downstream of the Youngdam Dam. The results showed that in upstream, the simulated water level by the CCHED was observed at 1.5 m higher than the 1-D numerical model (HEC-RAS) result since the HEC-RAS could not represent the bend geometry effect on streamflow. However, the calculated results by several empirical formula support that the CCHE2D is suitable for the super elevation simulation as well as flood stage and velocity in a natural channel bend.

연구목적 최근 검찰청 보고에 의하면 성폭력 피해자 중 강간 피해자는 17.1%이지만 성추행 피해자는 78.0%로 강간 피해자보다 그 수가 많았다. 이러한 성추행 피해자들에게도 심각한 정신적 증상이 다수 발생한다는 국외 보고가 있음에도 불구하고 이를 보고한 국내 연구는 없다. 따라서 본 연구는 성추행 성인 여성 피해자들의 정신적 증상을 조사하였고, 아울러 강간 피해자들의 이러한 증상들의 정도와 비교분석 하였다. 방 법 성폭력 발생 후 3개월 이내에 부산 스마일센터를 방문한 58명의 성인 여성 성폭력 피해자들이 대상자들이었다. 인구 통계학적 및 성폭력 관련 변인에 대하여 설문지를 이용하여 후향적으로 조사하였으며, 정신적 증상 중, 우울, 불안 증상의 심각도와 Posttraumatic stress disorder(PTSD) 유무는 Beck Depression Inventory (BDI), Beck Anxiety Inventory(BAI), Impact of Event Scale-Revised(IES-R) 자가보고형 척도를 이용하여 조사하였다. 결 과 총 58명 중 성추행 피해자는 36명(62.1%), 강간 피해자는 22명(37.9%)이었다. 성추행 피해자들 중 80.6%가 중등도 이상의 우울 증상, 83.3%가 중등도 이상의 불안 증상, 그리고 94.4%가 PTSD선별검사에서 유의미한 결과를 보였고, 이러한 정신적 증상에 대한 강간 피해자들에서의 비율(각각 95.5%, 95.5%, 95.5%)과 유의미한 차이가 없었다. 결 론 성추행 피해자들 또한 강간 피해자들만큼 대다수에서 우울, 불안 및 PTSD 증상이 동반되었다. 이러한 결과는 성추행 피해자들에서도 피해 초기부터 정신적 증상에 대한 적절한 평가와 조기 치료가 이루어져야 한다는 것을 시사한다. Objectives : According to the recent Korean National Police Agency report, rape victims were 17.1%, but sexual molestation victims were more than the rape victims by 78.0%. Despite many international reports about the occurrence of severe psychiatric symptoms in sexual molestation victims, there is no domestic research. Therefore in this study, we investigated psychiatric symptoms of sexual molestation victims, and we also compared it with psychiatric symptoms in rape victims. Methods : 58 women who visited Busan Smile Center within 3months after sexual violence were the study subjects. Questionnaire about sociodemographic and sexual violence related characteristics were retrospectively investigated. Of the psychiatric symptoms, Beck Depression Inventory(BDI), Beck Anxiety Inventory(BAI) for severity of depression and anxiety, and Impact of Event Scale-Revised(IES-R) to check the presence of posttraumatic stress disorder(PTSD) symptoms were used. Results : Of 58 sexual violence victims, sexual molestation victims were 36(62.1%) and rape victims were 22(37.9%). In sexual molestation victims, 80.6% had more than moderate severity of depression, 83.3% had more than moderate severity of anxiety, and 94.4% had significant scores at PTSD screening test. Compared with rape victims' psychiatric symptoms(each 95.5%, 95.5%, 95.5%) there were no significant difference. Conclusions : The majority of sexual molestation victims were also accompanied by depression, anxiety and PTSD symptoms as rape victims. There results suggest that appropriate assessment and early treatment for psychiatric symptom must be made in the early stage of injury in sexual molestation victims.

본 연구에서는 지점강우를 면적평균강우로 변환하는데 이용되는 DA(Depth-area)관계를 보다 효율적이고 정확하게 구축할 수 있는 자동 DAD분석기법을 국내의 유역에 적용하고 그 성능을 평가하는데 목적이 있다. 우선, 제안된 자동 DAD분석기법에는 격자기반의 공간강우분포를 호우중심으로부터 추적하는 방법으로 Box-tracking, Point-tracking, Advanced point-tracking으로 구분된다. 세 가지 방법을 용담댐 유역에서 발생한 호우 중 대표적인 10개의 호우사상에 대하여 적용한 결과, Advanced point-tracking을 적용하였을 경우가 다중호우중심을 가진 각 호우분포 형상을 정확히 고려하고, 보다 정확한 누적 시간별 누적 면적별 면적최대강우량(MAAR)을 산정할 수 있음을 확인하였다. 게다가, Advanced point-tracking이 선정된 여러 개의 호우중심으로부터 면적증가에 따른 각각의 MAAR을 동시에 산정하고 비교할 수 있어, 이에 따른 오차를 효과적으로 감소시킬 수 있음을 확인하였다. 마지막으로, 용담댐 유역의 10개의 호우사상에 대한 DAD 분석을 토대로 해당 유역의 DAD곡선을 누적시간별로 추출하였다. This study aims to apply and evaluate the automatic DAD analysis method, which is able to establish the depth-area relationship more efficiently and accurately for point-to-areal rainfall conversion. First, the proposed automatic DAD analysis method tracks the expansion route of area from the storm center, and it is divided into Box-tracking, Point-tracking, Advanced point-tracking according to tracking method. After applying the proposed methods to 10 events occurred in Yongdam-watershed area, we confirmed that the Advanced point-tracking method makes it possible to estimate the maximum average areal rainfal(MAAR) more accurately with consideration of the storm movement and the multi-centered storm. In addition, Advanced point-tracking could reduce the errors of the estimated MAAR induced by increasing the area because it can estimate MAAR for each storm center and compare them at the same time. Finally, the DAD curve for the study area could be derived based on the DAD analysis of the selected 10 events.

Objectives:Cognitive dysfunction is one of the major symptoms of schizophrenia, and has a diverse effect on the prognosis and course of schizophrenia. Several studies have been done about the correlation between cognitive dysfunction and clinical symptoms of schizophrenia, but the results of those studies were not clear. This study was performed to confirm the correlation between cognitive dysfunction and clinical symptoms of schizophrenia. Methods:We studied 117 patients with schizophrenia. We assessed clinical symptoms and the cognitive function of the patients, and analyzed the statistical correlation between clinical symptoms and the cognitive function. For clinical symptoms, Positive and Negative Syndrome Scale(PANSS), Clinical Global Impression-Severity(CGI-S) and Hamilton Depression Rating Scale(HDRS) were performed. For cognitive function, Digit Span Test, Visual Span Test, Stroop Color Word Test(SCWT), Continuous Performance Test(CPT), Wisconsin Card Sorting Test(WCST), and Digit Symbol Substitution Test(DSST) were performed. Results:There was significant correlation between CPT and clinical symptoms. The WCST revealed that Categories Achieved(CA) have significant correlation with disorganization symptoms among 5-factor model of PANSS (p<0.05). DSST revealed that the total score(p<0.01), negative syndrome(p<0.01), general psychopathology(p<0.01) among 3 kind major area classification of PANSS and disorganization symptoms of 5-factor model of PANSS(p<0.001) have significant correlation. Conclusion:This study revealed the correlation between the cognitive function and a part of clinical symptoms in patients with schizophrenia, as shown through the CPT, WCST and DSST.

Objectives : This study aimed to investigate quality of life, severity of depression, suicidality, subjective health and subjective stress of depression with subjective cognitive decline in Korean adults. Methods : We used the 7th KNHANES data to enroll 415 participants with a score of 10 or higher on Patient Health Questionnaire-9 (PHQ-9), aged 20-64. Depression was divided into two groups based on the presence/absence of subjective cognitive decline. Demographic and psychological characteristics were compared between two groups. Correlation analysis of subjective cognitive decline, quality of life, depression, suicidal idea was carried out. To detect which variables influenced quality of life, a multiple regression analysis was carried out. Results : Among the 415 participants, 98 had depression with subjective cognitive decline. We identified significant differences in age, marital status, education, employment between the two groups. After adjusting for these variables, depression with subjective cognitive decline had lower EuroQol-5D index scores, more severe depressive symptoms without cognition and worse subjective health than depression without cognitive decline. There was a significant correlation between subjective cognitive decline and quality of life (r=-0.236, p<0.001), suicidal idea (r=0.182, p<0.001), depression score without cognition (r=0.108, p=0.028). Through multiple regression analysis, subjective cognitive decline was predictor of reduced quality of life (β=-0.178, p<0.001). Conclusions : Depression with subjective cognitive decline has poor quality of life and severe depression. Cognitive decline should be considered to improve treatment result in depression. 연구목적 국내의 성인을 대상으로 주관적 인지 저하를 동반한 우울증에서 삶의 질, 우울의 심각도, 자살 관련 특성, 주관적 건강 상태 및 스트레스 인지에 대해 조사하고자 하였다. 방 법 국민건강영양조사 제 7기 자료를 이용하여 Patient Health Questionnaire (PHQ-9)에서 10점 이상인 인구 415명을 대상으로 하였다. 주관적 인지 저하 유무에 따라 두 군의 특성 차이를 비교했다. 주관적 인지 저하와 삶의 질, 우울, 자살사고의 상관성을 보기 위해 상관분석 및 회귀 분석을 실시했다. 결 과 주관적 인지 저하를 동반한 우울증 집단이 삶의 질과 주관적 건강이 더 좋지 않았고 우울의 심각도가 심했다. 주관적 인지 저하와 삶의 질은 음의 상관관계, 자살사고와 우울은 양의 상관관계를 보였다. 회귀 분석을 통해 주관적 인지 저하가 삶의 질에 부정적 영향을 미치는 것을 확인했다. 결 론 주관적 인지 저하를 동반한 우울증은 삶의 질을 저해하고 우울의 심각도가 심하며 삶의 질, 자살사고 및 우울을 악화시키는 것으로 확인되었다.

Objectives:We aimed to evaluate the relationship between disability self-awareness and insight in patients with schizophrenia. Methods:We enrolled 58 clinically stable patients with schizophrenia. The World Health Organization Disability Assessment Schedule (WHODAS) self-report was used to identify self-awareness of functional ability. The Positive and Negative Syndrome Scale (PANSS), Clinical Global Impression-Schizophrenia Scale (CGI-SCH), and Personal and Social Performance Scale (PSP) were utilized to evaluate clinical symptoms and global function. Whereas Insight Scale for Psychosis (ISP) was applied for insight. Statistical analyses were performed using correlation and linear regression. Results:The WHODAS had a significant correlation with the general psychopathology subscale and total score of PANSS, CGI-SCH, and PSP. Moreover, ISP had a strong correlation with the overall WHODAS score and all domains. In the linear regression analysis, ISP had significant effects on the overall WHODAS score after adjusting for additional variables. Conclusion:Disability self-awareness was significantly correlated with the level of insight in patients with schizophrenia. Clinicians need to consider patients’ insight during the discussion of functional ability.
