This paper describes the results from a prevention program for low-income mothers of children under the age of 13 aiming at the positive change on parental attitudes toward their children, parenting satisfaction and attitudes toward the use of corporal punishment. The program duration was 8 weeks and consisted of two parts: parent education on understanding parent-child relationship, communication skill improvement, techniques of problem solving, non-punitive child rearing techniques; and the recognition and use of existing social support network including networking of the neighborhood resources. The pre-post test control group design was employed. The results are: the program is effective on bringing some positive changes on an three variables: parental attitudes toward their children, parenting satisfaction and attitudes toward the use of corporal punishment. Increased social support was found to have significant positive effect on the above variables except the attitudes toward corporal punishment. To decrease the risk factors as well as to increase the protective factors of child abuse, well designed parent education and social support program is recommended on every community level.

경찰의 성폭력 수사행동을 결정하는 요인을 조사하고자, 경찰의 인지 및 태도(수사임무에 대한 법지식, 보호연계임무에 대한 인지, 성폭력에 대한 편견)와 실제 수사행동(적극적 수사와 이차폭력)의 관계를 검증하기 위한 이론적 모델을 설정하였다. 경남지역 세 도시의 남성경찰 354명으로부터 수집된 설문조사 자료를 토대로 구조방정식 모형검증을 실시한 결과 최종모델이 발견되었다(CFI=0.947,IFI=0.948, RMSEA=0.048). 분석결과, 적극적 수사행동을 결정짓는 요인은 수사임무에 대한 법지식, 보호연계임무에 대한 인지, 성폭력에 대한 편견인 것으로 나타났다. 수사임무에 대한 법지식과 보호연계임무에 대한 인지가 높을수록 적극적 수사행동이 증가되며, 반면 성폭력에 대한 편견은 적극적 수사행동을 감소시키는 것으로 나타났다. 한편, 이차폭력 행동을 결정짓는 요인은 수사임무에 대한 법지식인 것으로 나타났다. 수사임무에 대한 법지식이 높을수록 이차폭력 행동이 감소되었다. 특히, 성폭력에 대한 편견은 직접적으로 적극적 수사행동을 감소시킬 뿐 아니라, 수사임무에 대한 법지식과 적극적 수사, 보호연계임무에 대한 인지와 적극적 수사 사이에서 매개역할을 하는 것으로 나타났다. 연구결과를 토대로 적극적 수사를 강화하고 이차폭력을 최소화하기 위한 방안으로 성폭력관련 법에 대한 교육, 수사지침의 재정비, 의식전환 프로그램, 경찰의 전문화, 수사환경의 개선, 사회복지사와의 연계체계 구축 등이 제안되었다.

Objectives: Smoking among university students represents a formidable and global public health challenge. We assessed the associations between socio-demographic, health and wellbeing variables as independent variables, with daily smoking, attempts to quit smoking, and agreement with smoking ban as dependent variables. Methods: A sample of 3258 undergraduate students from eleven faculties at Assiut University, Assiut, Egypt, completed a general health questionnaire. Results: Overall daily or occasional smoking in last three months prior to the survey was about 9% (8% occasional and 1% daily smokers), and smoking was generally more prevalent among males (male=17%, female=0.6%, P < 0.001). After adjustment for confounders, not having normal BMI and having a mother who completed at least bachelor's degree education was positively associated with daily smoking, and conversely, no history of illicit drug use was a protective factor. About 76% of smokers had attempted to quit smoking within the last 12 months prior to the survey. Although a large proportion of students agreed/strongly agreed with the banning of smoking at university altogether (87%), such agreement was less likely among smokers. Conclusion: There is need for implementation of non-smoking policies on university premises, as well as regular up-to-date information on, and the periodic/yearly monitoring of tobacco use by university students employing standardised data collection instruments and reference periods. In addition, it would be valuable to develop campus-based educational/ awareness campaigns designed to counteract tobacco advertisement directed towards young people in Middle East countries. Otherwise, the danger could be that the current relatively low smoking prevalence among university students may escalate in the future.

In recent years, meteorological disasters have frequently occurred in rural areas. As a result, there have been growing concerns over the protective measures needed. In order to avoid natural risks and damage, and to strengthen countermeasure to meteorological disasters, local governments needs to be prepared. Therefore, this paper seeks to prevent meteorological disasters through mapping of inundation vulnerability in agricultural land, Chungcheongnam-do. In doing so, this study were considered 5 variables (i.e. precipitation, region of altitude below 50m, region of slope gradient is below 10 degree, distance from river within less 50m) for creating vulnerability map. The precipitation was excluded in five variables. Since, the precipitation which include Daily maximum precipitation, 2-Daily maximum precipitation, summer precipitation was not any correlation among them. The results of analysing four variables, exclusive of precipitation, were showed that the agricultural lands where located in Dangjin, Buyeo, Hongseong and Asan were low correlation of inundation vulnerability by overlapping analysis. Moreover, The correlation analysis was showed low correlation between each factors and the annual average area of agricultural lands' inundation, whereas, the correlation analysis which was overlapping each factor showed high correlation. In conclusion, in order to create reliable vulnerability map in agricultural lands, Chungcheongnam-do, it must be considered to overlap analysis of the four main factors such region of altitude below 50m, region of slope gradient is below 10 degree, distance from river within less 50m. We suppose that this study's analysis can help to set the preparedness site of agricultural lands inundation.

In contemporary society, neglected families increase adolescents' maladjustment behaviors, causing academic problems, psychological and emotional problems, and showing flight behavior. By identifying the nature of the protective factor against the dangerous environment of a neglected family and increasing the protection factor for the children in a dangerous environment, it is necessary to create the environment so that the young can grow up positively rather than adversely. The purpose of this study is to identify the characteristics of adolescents who are psychologically adaptive at the level of general family children among the adolescents who are in a dangerous environment. The results showed that self - esteem, ego - resilience, ego - identity, and community variables had a significant effect on discriminating adolescents who showed high psychological adjustment from risk factors of neglect while controlling other factors. SPSS 20.0 was used to analyze the data.

Hemorheology plays an important role in atherosclerosis. Hemorheologic properties of blood include whole blood viscosity, plasma viscosity, hemaocrit, RBC deformability and aggregation, and fibrinogen concentration in plasma. Blood flow is determine by three parameters (pressure, lumen diameter, and whole blood viscosity), whole blood viscosity is one of the key physiological variables. However, the significance of whole blood viscosity has not yet not been fully appreciated. Whole blood viscosity has a unique property, non-Newtonian shear-thinning characteristics, which is primarily due to the presence of RBCs. Hence, RBC deformability and aggregation directly affect the magnitude of blood viscosity, and any factors or diseases affecting RBC characteristics influence blood viscosity. Therefore, on can see that whole blood viscosity is the causal mechanism by which traditional risk factors such as hypertension, hyperlipidemia, smoking, exercise, obesity, age, and gender are related to atherogenesis. In this regard, we included whole blood viscosity in the three key determinants of injurious pulsatile flow that results in mechanical injury and protective adaptation in the arterial system. Because whole blood viscosity is a potential predictor of cardiovascular diseases, it should be measured in routine cardiovascular profiles. Incorporating whole blood viscosity measurements into a standard clinical protocol could improve our ability to identify patients at risk for cardiovascular disease and its complications.

The analysis of distribution line faults is essential to the proper protections in the power system. A high impedance fault does not make enough current to cause conventional protective devices. In this paper, Fractal dimensions are estimated for distinction between normal status and fault status in the power system. Application of the concepts of the fractal geometry to analyze chaotic properties of high impedance fault current was described. In addition, to analyze variation of fault current and normal current on phase plane, embedding state variables are reconstructed from 1 dimensional time series.

The purpose of this study was to investigate adolescents' individual and microsystem variables including relationships with parents and friends affecting adolescents' experiences of mobile social networking site (SNS) cyberbullying based on the human ecological perspective. Data came from 344 middle school students who lived with both their parents in the Seoul and Gyunggi areas. A multiple regression analysis showed that adolescents' characteristics, relationships with parents, and friends were associated with their experiences of mobile SNS cyberbullying. These findings suggest that good relationships with parents could be protective factors for adolescents to reduce mobile SNS cyberbullying. However, adolescents' characteristics including aggression, depression, and delinquent peers were positively associated with adolescents' experiences of mobile SNS cyberbullying. This study highlights that various environments are closely related to adolescent development.
