Objectives After the initial investigations by the Korea Centers for Disease Control in 2011, over 1000 suspicious cases of humidifier disinfectant (HD) victims were subsequently reported by 2015, and numbers are still increasing dramatically in 2016 in the midst of the prosecutors' office investigation. This study attempts to summarize the current understandings of the related health effects of HD based upon a systemic review of published epidemiologic studies and toxicology investigations. Methods Published studies of HDs were searched through PubMed and TOXLINE under the search words 'humidifier disinfectant,' and related reports were identified from the references and published report list of regulatory agencies including the Korean National Institute of Environmental Research, US Environmental Protection Agency, and EU European Chemicals Agency. Results Case reports and epidemiologic studies have reported the clinical features of severe forms of HD lung damage, together with epidemiologic findings of seasonal occurrence and demographic variations, including the heightened susceptibility of young children. Toxicological studies have reported inhalation toxicities together with positive findings of in vitro genotoxicity studies. Conclusions This study examined unsolved issues based on cases of upper respiratory diseases and diseases of other organs, including cancers, among suspected victims of HDs. These issues should be clarified in future research for the management and prevention of health effects from HDs and chemicals of other related household products.

Cyber attacks are increasing continuously. On average about one million malicious codes appear every day, and attacks are expanding gradually to IT convergence services (e.g. vehicles and television) and social infrastructure (nuclear energy, power, water, etc.), as well as cyberspace. Analysis of large-scale cyber incidents has revealed that most attacks are started by PCs infected with malicious code. This paper proposes a method of detecting an attack IP automatically by analyzing the characteristics of the e-mail transfer path, which cannot be manipulated by the attacker. In particular, we developed a system based on the proposed model, and operated it for more than four months, and then detected 1,750,000 attack IPs by analyzing 22,570,000 spam e-mails in a commercial environment. A detected attack IP can be used to remove spam e-mails by linking it with the cyber removal system, or to block spam e-mails by linking it with the RBL(Real-time Blocking List) system. In addition, the developed system is expected to play a positive role in preventing cyber attacks, as it can detect a large number of attack IPs when linked with the portal site.

The first objective of this study is to examine the finanacial management practices of rural housewives. The second objective is to determine the effects of sociodemographic characteristics on financial management practices. The Deacon & Firebaugh's model of family resource management framework and previous studies were used to determine the effects, regarding a9e, income, number of family, education level, and farming/nonfarming as independent/input variables, and monthly saving and managerial behavior index as dependent/throughput variables. A sample of 179 rural housewives aged less than 60 was selected from Shihung-Si Gyonggi-Do Province. Results showed that rural housewives more frequently did keeping bills, making purchase-list and verifying purchase need than recording where money spent making financial plan, and evaluating spending. With regard to household debt use, 60% of the sample had debt the most borrower used debt for farming, 73% of borrowers paid for their debt behind the schedule, and the main source of borrowing was NACF (NongHyup). Using installment credit, the rural housewives mainly bought cosmetics. 25% of the sample had credit cards. Average debt was 6, 070, 000 won, and 81% of annual income. In terms of saving, 85% of the sample saved, and 23% of the sample lived with the money after save. The main reasons of saving were for education and marriage of children and emergency. The main saving institutions were NACF and NLCF (ChukHyup). The regression showed that income was negatively associated with monthly saving, and age was identified as the positive determinants of managerial behavior index.

Purpose: This study was to examine the degree of prenatal emotional status, preparation for delivery, postpartum social support, and postpartum blues and to investigate the relationship of the above variables in postpartum women. Method: The subjects were 131 postpartum women. Selection criteria were women who were 2 to 8 weeks post delivery. After Informed consent was obtained, they were asked to fill out a self-administered questionnaire. The instrument was a Postnatal Depression & Anxiety check list. Result: The mean age of the subjects was 29.3 years, and 63.4% of subjects delivered their children by vaginal birth. 18.3 percent had felt depressed during their pregnancy. The mean score of the postpartum blues was 19.2. 61.8 percent of the subjects had postpartum blues and 8.4 percent experienced postpartum depression. Monthly income was negatively correlated to postpartum blues (r=-.189, p<.05), but the emotional status during pregnancy had a significant and positive relationship. However, preparation for delivery had no significant correlation with postpartum blues. While husband support and social support had a tendency to have a negative correlation. Conclusion: Further research is needed to identify the factors that affect the emotional status during pregnancy with various scales. Also, intervention programs to increase emotional support for pregnancy and husband support are needed.

Purpose: This study was to identify the relationship between stress, social support and depression in the elderly. Method: The subjects were 283 elderly adults over 60 in Seoul. Data was collected by questionnaire surveys using convenience sampling. The instruments used in this study are the ELSI developed by Aldwin(1990), the Interpersonal Support Evaluation List developed by Cohen & Hoberman (1983), and the Geriatric Depression Scale by Yesavage & Brink(l982). Data was analyzed by the SAS program, using descriptive statistics, Pearson Correlation Coefficient, t-test, ANOVA and progressed Multiple Regression. Result: The relationship between stress and depression had a positive correlation (r=0.33), but the relationship between stress and social support had no significant correlations. The relationship between social support and depression had a negative correlation (r=-0.38). The most powerful predictor of depression was the economic status and then a combination of stress, and social support account for 39% of the variance in depression in the elderly. Conclusion: These results suggested that stress and social support deficits can be potential risk factors in old age depression. Therefore, these findings give useful information for constructing an intervention program focused on depression in the elderly.

ADHD is a neuro-developmental disorder that begins in childhood, yet may continue into adulthood. Although 3 to 4 percent of adults are affected by ADHD, but only a small proportion of adults ever receive a formal diagnosis and treatment. The core symptoms of ADHD frequently lead to significant academic difficulties that often result in the students' teacher being the first to suspect the disorder. In order for school teachers to effectively deal with ADHD students in school classrooms, they need to have positive attitude toward ADHD students. This study presents a list of ADHD-related web sites which provide educational contents and support for school teachers, and provides the discussions about the current status and the roles of those web sites.

Sustainable interior design is defined as interior design in which all systems and materials are designed with an emphasis on integration into a whole for the purpose of minimizing the negative impacts and maximizing the positive impacts on environmental, economic, and social systems over the life cycle of the interior components of a building. To achieve sustainability, it is important to pay attention to the design factors that significantly affect environmental eco-system. The purpose of this study was to describe how interior designers applied sustainable intoner design factors and how important they perceived sustainable interior design factors to be. Internet-based survey of interior design practitioners was conducted to collect data. A random sample was drawn from the American Society of Interior Designers membership list. Findings indicated that although interior designers acknowledge the importance of sustainable design practice, they have not frequently applied it to their projects. The results of this study suggest future educational strategies for students majoring in interior design and continuing education for intoner design professionals.

The purpose of this study was to examine the impact of parenting stress on children's problematic behavior in multicultural families. The subjects were 143 mothers who are caring for their 3-6 year old children in multicultural families. Data was collected using a parenting stress index and a child behavior check list. The data were statistically analyzed using a t-test, a one-way ANOVA(Scheff'e test), a correlation analysis and multiple regression analysis. The study showed that there were no significant differences in parenting stress according to the socio-demographic variables. However, there were some significant differences in children's problematic behavior according to the mother's education. Correlation analysis indicated that the mother's parenting stress and children's problematic behavior in multicultural families had significant positive correlations in all sub-variables. It was also found that the mother's education, the mother's stress caused by a difficult child, the mother's stress caused by dysfuntional interactions between parents and children and educational distress, were all significant predictors of the preschool children's problematic behavior in multicultural families.
