가뭄은 국민생활 및 경제 등에 막대한 손실을 초래하며, 지역사회 공동체나 사회기능에 심각한 영향을 끼칠 수 있는 재해이다. 가뭄피해 최소화를 위해서는 단기대응, 복구지원 등의 사후대책에서 사전대비 및 예방으로의 정책 전환이 필요하며, 이러한 정책 수립을 뒷받침하기 위해서는 가뭄에 따른 정량적인 피해영향 평가가 우선적으로 필요하다. 하지만 가뭄 피해의 범위 및 형태는 워낙 광범위하기 때문에, 피해추정을 위한 잣대라 할 수 있는 영향평가 기법조차 제대로 정립되지 못하고 있는 실정이다. 국내에서는 분야별(기상, 농업, 수문)로 지수화 된 지표를 이용한 가뭄 평가가 주로 수행되고 있으며, 경제적 영향평가는 방법론에 대한 시범 연구 수준이다. 가뭄기록조사 등 과거 가뭄피해 자료에서도 피해액의 금액환산이 되지 않은 사례가 대부분이며 급수차지원, 관정개발 등 사후복구비 위주의 일부 자료만이 피해금액으로 제시되어 있을 뿐이다. 댐, 저수지 등에 의한 용수공급 안정성으로 인해, 기상학적인 가뭄이 즉시 물부족으로 인한 피해로 이어지지는 않지만, 물부족이 발생하거나 부족량이 예측되는 상황에서 피해규모를 시스템적으로 추정 및 비교할 수 있는 기법 개발의 필요성에 의해 잠재피해액 개념의 공급지장비용 추정기법을 개발하였다. 공급지장비용 또는 편익 도출을 위한 이론적 배경으로, 경제적 가치 또는 파급효과를 분석하기 위한 방법은 경제학적 접근법과 비경제학적 접근법으로 구분된다. 경제학적 접근법에서 사용하는 진술선호 기법의 경우 전국을 대상으로 설문 등의 과정을 거쳐 지불의사액을 도출하는 과정이 필요하기 때문에 많은 조사비용이 소요된다. 비경제학적 또는 공학적 접근법으로 분류되는 대체비용법은 이론적 배경이 약하고 대체항목의 선택에 주의가 필요하다는 단점이 있으나, 물가자료, 산업통계, 수자원통계 등 기초자료의 주기적 업데이트가 유리하며, 정신적 피해를 제외할 경우 피해비용 추정결과의 편차가 진술선호기법 보다는 작은 장점이 있다. 본 연구에서는 피해비용의 과대추정에 유의하여 대체비용법에 기반한 일본 후생노동성의 감 단수피해추정기법을 우리나라 자료에 맞게 수정하여 공급지장비용을 추정하였으며, 경제학적 접근법에 의한 용수의 한계가치비용 등과 비교를 통해 적용성을 검토하였다.

본 논문에서는 바이오인식 정보 기술(얼굴, 정맥, 지문, 홍채)을 이용하여 신뢰성 있는 Ubiquitous-Healthcare(U-HC) 서비스를 지원하는 사용자 인종 메커니즘과 암호화 기법을 제안한다. U-HC 서비스에 태동 및 특징, 국내외 산업현황, 기대효과 등을 통해 U-HC서비스의 필요성을 강조하고 있다. 하지만 지능화 및 고도화된 기술을 통하여 개인 정보를 악의적인 의도로 유출하여 개인에게 육체적 정신적 경제적 피해를 주고 있다. 바이오인식은 이러한 피해를 막고 보안 및 프라이버시 측면의 취약점 및 공격들을 분석하여 효율적으로 방어함으로서 개인의 의료정보 및 바이오 정보를 보호하기 위한 대응책인 새로운 사용자 인증과 암호화 기법이다. 사용자 인증 기법은 다수의 바이오 정보들을 인증 시에 무작위로 선택하여 2개 이상 입력하는 방안이며 암호화 기법은 사용자 스토리(Story)식 암호화(Encryption) 기법을 제안한다. 이러한 방법론을 통하여 효율적이며 신뢰 성 있는 U-HC 서비스를 보장하고자 한다.

이메일 서비스 사용자들은 스패머가 무차별적으로 발송하는 스팸메일에 의한 정신적 경제적 피해를 입고 있다. 이러한 피해를 막기 위해 필터링, RBL (Real-time Blackhole List)과 같은 스팸차단 기법이 등장하였고 많은 메일서버에서 사용되고 있다. 그러나 이는 스팸메일의 근본적인 원인은 해결하지 못하며, 높은 차단율을 유지하기 위해서는 지속적인 관리 및 업데이트가 필요하다. 이러한 한계점을 극복하기 위한 기법으로 송신자 자가인증 기법이 있다. 본 논문에서는 송신자 자가인증 기법을 적용하여, 스팸메일을 근본적으로 차단하고 지속적인 업데이트가 필요 없는 스팸차단 서버 및 애플리케이션을 구현하였다.

Bullying has recently become a serious social problem in Korean society. Bullying, which is defined as a phenomenon that one particular student is intensively and continuously harassed or ostracized by a group of students, is apt to produce harmful effects on bullies as well as victims. Bullying has many causes including those originated from the personality of victims and bullies. This study is designed to investigate the difference in personality trait between victims, bullies, victims/bullies, and neither. The subjects of this study were 215(115 male and 100 female) 6th-grade students in the primary school in Seoul. Questionnares were distributed to the students and their carers. The student carers were also asked to answer the questions for a survey called the Korean Personality Invertory for Children(KPI-C). SPSS was used for the statistical analysis of the collected test information；ANOVA, post hoc scheffe test, and T-test were used to analyze the differences between the tested groups. The result of the study is as follows. 1) The victims, bullies, victims/bullies and neither totaled respectively 11(5.1%), 56(26.0%), 11(5.1%) and 137(63.7%). 115 were male and 100 were female. 2) The frequency of victimized is as follows：1 time is 15(7.0%), 2 times is 4(1.9%) and more than 3 times is 3(1.4%). The frequency of bullying is as follows；1 time is 40(18.6%), 2 times is 17 (7.9%) and more than 3 times is 10(4.7%). 3) The differences between froups in KPI-C test is as follows. (1) The ESR(p=.00) scale was significantly lower in the victims group than in the neither group and the HPR(p=.00) scale and PSY(p<.01) scale were significantly higher in the former than in the latter. (2) The ESR(p=.00) scale was significantly lower in the victims/bullies group than in the neither group and the SOM(p=.00) scale and HPR(p=.00) scale were significantly higher in the formaer than in the latter. (3) The SOC(p=.00) scale, PSY(p<.01) scale and AUT(p=.00) scale were significantly higher in the victims group than in the bullies group. (4) There is statistically no difference between the bullies group and the neither group. To conclusion, Victims need to learn how to cope with harsh situations, or they will have to face difficulties in relationships. Even after they experience bullying, they may not realize why they have been bullied, or speak out for themselves.

This study looked at how children's mental health is affected by Domestic violence and school violence at home and school after Covid-19, as well as how these victim experiences relate to children's mental health. This study surveyed 650 students from 14 middle schools in Wanju, Korea. The moderating effect of smartphone overdependence in the experience of violence and mental health was investigated. Major research findings: First, children's exposure to domestic violence and school violence has a significant impact on smartphone dependence. Second, children's exposure to domestic and school violence has a significant impact on their mental health. Third, it has been demonstrated that smartphone dependence is statistically significant in the relationship between domestic and school violence. Based on these findings, we present a convergent intervention and practice strategy for children in the Covid-19 era to cope with mental health problems and expand the support system.

This study was conducted to confirm the effect of noise generated by military training on the life satisfaction of residents living near military facilities. In 2017, an interview survey was conducted on 904 adult residents living near military facilities. The life satisfaction score of the survey subjects was analyzed to be 3.17 out of a total of 5 points, which was confirmed to be lower than that of previous studies on adults. Factors influencing the life satisfaction of residents around military facilities were analyzed. Life satisfaction as dependent variables, demographic factors and physical damage experience factors, and mental damage experience factors were selected as independent variables. As a result of regression analysis, it was analyzed that monthly average household income (coef.=0.09, p<0.001), emotional anxiety (coef.=-0.34, p<0.001), and stress (coef.=-0.05, p<0.001) affected life satisfaction. This study is expected to be used as basic data for establishing policies to improve the life satisfaction of residents living in areas around military facilities.

The authors surveyed extrafamilial sexual abuse in the children under 15years old by the physician's reports. We sent the semi-structured child sexual abuse questionnaires to 7055 board certified pediatrics, obstetrics and gynecology, family medicine and emergency medicine. Total respondents were 1205. The results from these respondents were as followings. 1) The number of respondents who have had the experience of treating victims of extraf/amilial child sexual abuse were 641(53.2% of total respondents). 2) 338(52.7%) of the perpetrators were known persons and 277(43.2%) were strangers, the most common age bracket were 20s, 30s and 10s, and almost all(99.8%) of the perpetrators were male. 3) The mean age of victims was $9.7{\pm}3.5$ years old, and almost all(98.6%) of the victims were female. 4) The ways by which extrafamilial child sexual abuses were found were victim’s own reports：273(62.6%), pain complaint, 156(24.3%) and abnormal behavior 96(15.0%), other person’s report 72(11.2%), detection during examination 19(3.0%), and pregnancy 4(0.6%). 5) Time lags between extrafamilial child sexual abuses and hospital visits were within 24 hours 332 (51.8%) and from 1 day to 1 week 232(36.2%), victims were rather quickly 6) Physical complications were perineal wound 571(89.1%), hymen rupture 349(54.4%), wound of other part of body 124(19.3%), pregnancy 37(5.8%), and sexually transmitted disease 18(2.8%), and other serious complications such as vaginal-rectal lacerations 8, intastinal bleeding 7, death 2, hypotensive shock 1. These results suggest considerable numbers of physicians have had the experience of treating victims of extrafamilial child sexual abuses, and extrafamilial child sexual abuses are the major medical as well as social issue in children in Korea.

Due to the deepening of COVID-19, high-intensity social distancing has been prolonged and many social problems have been cured. In particular, physical and psychological isolation occurred due to the non-face-to-face system and a lot of damage occurred. The various social problems caused by Corona acted as severe stress for all those affected by Corona 19, and eventually acted as a factor threatening mental health such as depression. While the number of people suffering from mental illness is increasing, the actual use of mental health services is low. Therefore, it is necessary to establish a system for people suffering from mental health problems. Therefore, in this study, depression detection and emergency detection models were constructed based on sensor information using smartphones from depressed subjects and general subjects. For the detection of depression and emergencies, VAE, DAGMM, ECOD, COPOD, and LGBM algorithms were used. As a result of the study, the depression detection model had an F1 score of 0.93 and the emergency situation detection model had an F1 score of 0.99. direction.

The purpose of this study was to explore anger and its expression, psychoticism, addiction, and coping styles of victims, especially aggressive victims of dating violence, and to provide valuable information for prevention of dating violence and rehabilitation of victims. The participants were 477 female college students who had the experience of heterosexual dating relationships, whose ages ranged from 17 to 29 (M=20.59, SD=1.44). The psychological tests used in this research included the following: Straus' Conflict Tactics Scale, Spielberger's State-Trait Anger Expression Inventory, Eysenck Personalty Inventory, and multidimensional Coping Scale. Results revealed that victims only were more likely to receive violence as well as sexual harassments from their dating partners than aggressive victims of dating violence. Aggressive victims of dating violence showed higher level of trait anger and anger-out, and difficulty in control their anger than victim only and women who had not experienced dating violence. In addition, they also revealed symptoms of paychoticism and addiction. And aggressive victims of dating violence showed less active coping and more active forgetting and renunciation than victims only and women who had not experienced dating violence. Victims only of dating violence more like to criticize themselves and pursue religious coping than aggressive victims. Researcher discussed these results with previous studies.
