PVDF (polyvinylidene fluoride) nanofiber has the advantages such as excellent strength, chemical resistance, nontoxic, non-combustibility. Flat membranes with 0.3 and $0.4{\mu}m$ pore size respectively, were manufactured by PVDF nanofiber, and then each spiral wound module was prepared with them. A woven paper was not included in preparing the module with $0.3{\mu}m$ pore size; however, it was included the module with $0.4{\mu}m$ pore size. The permeate fluxes and rejection rates of the two modules were compared using pure water and simulation solution including kaolin and humic acid. The recovery rate and filtration resistance were calculated after water back-washing. In addition, the effect of flow rate and trans-membrane pressure on treatment efficiency and filtration resistance were investigated for the spiral wound module with $0.4{\mu}m$ pore size.

The purpose of this study was to examine the effect of cyber bullying prevention education on university students. The subjects were 64 college students and were assigned to experimental group or Comparison group. The experimental group(n = 33) was educated about cyberbullying coping strategies, and the Comparison group(n = 31) was educated about general cyberbullying We used the Basic Emotions Scale, Helplessness Scale, and Competence Scale to confirm the efficacy of the education. Results, Both the experimental group and the Comparison group showed less negative emotions and helplessness after the education than before the education. In the experimental group, competence was significantly higher than the Comparison group. These results suggest that the inclusion of coping strategy is more effective in increasing competence than cyber bullying prevention education. Finally, the limitations of this study were discussed along with suggestions for further research.

Objectives : Childhood is a critical period involving various developmental tasks that need to be accomplished. Childhood depression has overall negative implications for certain areas of development, including cognition, emotion, social skills, academic achievement, and ability to cope with stress. Yet, because depression can be "masked" by accompanying behavioral problems, early detection and diagnosis of childhood depression is somewhat challenging. In this study, using the Korean version of the Child Behavior Checklist (K-CBCL), we evaluated the association between children's self reports on depression and parents' assessment of children's behaviors. Methods : Subjects were recruited from the S city, a cohort comprising a non-random convenience sample of 226, 10-year-old ethnic Koreans in their fourth year of elementary school and their parents. All participants underwent several tests, including Children's Depression Inventory (CDI) and K-CBCL. Results : A total of 226 children, including 166 boys (73.5%) and 60 girls (26.5%), participated in the study. The average CDI for the participants was 14.57 (SD=7.54). Two items on the K-CBCL, total scale of adjustment scale and social withdrawal problems, showed a close association with the CDI. Conclusion : Although much remains to be elucidated, after controlling for covariates, the results of this study suggested that behavioral problems observed in children may be closely associated with depression.

This study presents a modeling of aerosol extinction vertical profiles in Korea by using the Moderate Resolution Imaging Spectro-radiometer(MODIS) derived aerosol optical thickness(AOT) and ground based visibility observation data. The method uses a series of physical equations for the derivation of aerosol scale height and vertical profiles from MODIS AOT and surface visibility data. The modelled results under the standard atmospheric condition showed small differences with the standard aerosol vertical profile used in the radiative transfer model. Model derived aerosol scale heights for two cases of clean(${\tau}_{MODIS}=0.12{\pm}0.07$, visibility=$21.13{\pm}3.31km$) and hazy atmosphere(${\tau}_{MODIS}=1.71{\pm}0.85$, visibility=$13.33{\pm}5.66km$) are $0.63{\pm}0.33km$ and $1.71{\pm}0.84km$. Based on these results, aerosol extinction profiles can be estimated and the results are transformed into the KML code for visualization of dataset. This has implications for atmospheric environmental monitoring and environmental policies for the future.

A Weibull statistical analysis of the mechanical properties of SiC ceramics was carried out by immersion in acidic and alkaline solutions. The heat treatment was carried out at 1373 K. The corrosion of SiC was carried out in acidic and alkaline solutions under KSL1607. The bending strength of corroded crack-healed specimens decreased 47% and 70% compared to those of uncorroded specimens in acidic and alkaline solutions, respectively. The corrosion of SiC ceramics is faster in alkaline solution than in acid solution. The scale and shape parameters were evaluated for the as-received and corroded materials, respectively. The shape parameter of the as-received material corroded in acidic and alkaline solutions was significantly more apparent in the acidic solution. Further, the heat-treated material was large in acidic solution but small in alkaline solution. The shape parameters of the as-received and heat-treated materials were smaller in both acidic and alkaline solutions.

The aim of this study was to develop and validate measures of a mother's reaction to children's negative emotions. After construct factors of a mother's reaction to children's negative emotions based on the theoretical basis and existing scales were explored, the first preliminary items were extracted. After the content validity was confirmed by expert opinions, the second preliminary items were composed, and the initial survey was carried out. Using exploratory factor analysis, three principal factors and 21 items were revealed to be most suitable. The factors of the scale consist of emotion-coaching-reactions, oversensitive reactions, and emotion-minimizing-reactions, respectively. In addition, the reliability analysis and validation analysis of the scale was conducted, by means of surveying 413 elementary students. The internal coherence reliability and test-retest reliability were verified as was the general internal coherence and timing stability of the scale. There were three additional verifications to validate the scale. (1)For the evidence based on internal structure, the confirmatory factor analysis and convergent-discriminant evidence; this resulted in confirming the factor structure of the scale as being reliable. (2)In order to understand the relationships to other variables, the correlation analysis came in effect to the overall scale and each of its sub-factors, showing that they are significantly correlated with the scale of the child's perception on rearing attitudes of the mother. (3)As for evidence based on the consequences of the test, the correlation analysis produced a result showed that sub-factors of the scale have as significant correlation with the child's emotional intelligence and resilience.
