  • This study evaluated the content of Korean vocabulary learning applications with a focus on tablet PC applications. We analyzed 51 Korean vocabulary learning applications. The instruments in this study were developed based on Yoo et al. (2012)' Vocabulary Learning Game Application Evaluation Criteria and Hyun et al. (2013)' Educational Application Evaluation Criteria. Data were analyzed using a t-test and one-way analysis of variance. The main results are as follows. First, each criteria's score was fairly good; the ease of use had the highest scores and the amusement had the lowest scores. Second, there was a significant difference in the interaction by vocabulary teaching approach. Applications based on a whole language-teaching method had higher scores than applications based on a phonics instructional teaching method inducing more operation and with immediate feedback. Third, there was significant difference in the sum of score and each criteria of developmental appropriateness, educational values, amusement, function and interaction by type of learning. Applications of combining type had higher scores in every criteria except for ease of use than applications of description type. These findings provide a preliminary evidence that the systematic Korean vocabulary learning application facilitates preschoolers' vocabulary learning.

  • Purpose: There has been a considerable increase in the number of women giving birth at advanced age. The genetic screening of such women is highly desirable. Clinical nurses, however, are not adequately trained to assist such clients. This study aims at identifying the educational needs of nurses in order for them to provide better care and treatment for such women. Methods: 206 South Korean clinical nurses participated in this study. Study variables were measured by nurses' attitudes toward terminating pregnancy (ATP), knowledge of prenatal genetic screening and diagnosis (K-PGSD), and information needs for prenatal genetic screening and diagnosis (I-PGSD). The statistical analysis included T-test, analysis of variance and Pearson's Correlation Coefficient. Results: Mean scores were 34.57±5.73 for ATP, 16.44±3.04 for K-PGSD, and 78.81±10.95 for I-PGSD. The findings demonstrate that nurses have high information needs (I-PGSD) to take better care of women who have positive results from their amniocentesis tests. Conclusion: Information needs among clinical nurses are not currently being met. Education for nurses must include training in counseling to encourage patients' autonomous decision-making regarding their pregnancies.

  • In the nuclear power plant, emergency core coolant system(ECCS) is furnished at reactor coolant system(RCS) in order to cool down high temperature water in case of emergency. However, in this coolant system, it occurs thermal stratification phenomena in case that there is the mixing of cooling water and high temperature water due to valve leakage in ECCS. This thermal stratification phenomena raises excessive thermal stresses at pipe wall. Therefore, this phenomena causes the accident that reactor coolant flows in reactor containment in the nuclear power plant due to the deformation of pipe and thermal fatigue crack(TFC) at the pipe wall around the place that it exists. Hence, in order to fundamental identification of this phenomena, it requires the experimental research of modeling test in the pipe flow that occurs thermal stratification phenomena. So, this paper models RCS and ECCS pipe arrangement and analyzes the mechanism of thermal stratification phenomena by measuring of temperature in variance with leakage flow rate in ECCS modeled pipe and Reynold number in RCS modeled pipe. Besides, results of this experiment is compared with computational analysis which is done in advance.

  • Psycho-educational interventions are not a substitute for analgesics, but they may serve as adjuvant therapy. Nurses can provide psychoeducational programmes to cancer patients to assist them in optimizing behavior that strengthen adjustment. The aim here was to determine the effects of psychoeducation on levels of adjustment to cancer in stage I-II breast cancer patients who met the study criteria (experimental group: 38 women, control group:38 women). The psychoeducational program consisted of eight 90 minute weekly sessions and data were collected using a questionnaire and the Mental Adjustment to Cancer Scale three times: before, six weeks and six months after the intervention. Data analysis was performed using descriptive statistical methods as well as the Chi square test, the Mann Whitney U test, repeated measures analysis of variance, the matched pairs t test and the Post Hoc Bonferroni test. The results at 6 weeks and 6 months after the program revealed that the experimental group had higher levels of "fighting spirit", lower levels of "helplessness/hopelessness, anxious preoccupation and fatalism" but there was no significant change in levels of "avoidance/denial" compared to the control group with regard to adjustment to cancer. In this study, psychoeducation was shown to cause positive changes in levels of adjustment to cancer in breast cancer patients

  • This study examined the attitude and education need for food safety of high school students. Data were collected from 297 high school students in Gyeongbuk province through a self-administered questionnaire on December, 2008. Frequency, t tests, one-way analysis of variance, Duncan's multiple range tests, and chi-square tests were conducted using SPSS V. 14.0. Many respondents answered that the foods produced and distributed in Korea were not safe enough. Over a third of the respondents replied that the produced and distributed foods were not safe because of unsanitary food processing. They pointed out food additives threatened food safety the most, which was followed by heavy metal contamination, and endocrine disruptors. Most respondents mentioned difficulties in acquiring information concerning food safety, and obtained information from the media, such as TV and radio. The respondents required a high level of education regarding food safety, and preferred movie clips and broadcasting media the most. Finally, they pointed out food-related government organizations to be the most efficient educational institution for food safety.

  • In this study, we turning mold steel (SKD61) using whisker reinforced ceramic tool (WA1) to get affected factor to surface roughness and regression equation. For this study, we adapt system of experiments. Results are follows; From the analysis of variance, it was found that affected factor to surface roughness was feed rate, cutting speed, depth of cut in order. From multi-regression analysis, we calculated regression equation and the coefficient of determination($R^2$). $R^2$ was 0.978 and It means regression equation is significant. Regression equation means if feed rate increase 0.039mm/rev, surface roughness will increase $0.8391{\mu}m$, if cutting speed increase 50m/min, surface roughness will decrease $0.034{\mu}m$, if depth of cut increase 0.1mm, surface roughness will increase $0.0203{\mu}m$. From the experimental verification, it was confirmed that surface roughness was predictable by system of experiments.

  • Purpose: This study was done to explore disease factors in children with epilepsy, parental factors and resource factors that are related to parenting stress and identify effects of each factor on parenting stress. Methods: Participants were 131 parents who had children who visited a hospital or were hospitalized due to epilepsy. Data collection was done between September 17 and November 17, 2012, and self-report surveys were used. Results: In Stepwise multiple regression analysis, factors influencing parenting stress in children with epilepsy were marital communication, educational background of parents, parenting efficacy, children's development delay, drug treatment and surgical treatment as a method of epilepsy treatment. These factors explained 34.6% (F=13.22, p<.001) of the variance in parenting stress. Conclusion: The findings indicate that parental factors (educational background of parents and parenting efficacy) and resource factors (marital communication) have higher explanatory power than disease factors of the children. Thus, it is importance to assess the capacity of parents through self-evaluation, and to assess barriers to marital communication when developing parenting stress intervention programs. Furthermore, both parents should be involved in interventions for parenting stress.
