Purpose: To examine the effects of a smartphone application-based exercise program on self-efficacy expectations (SEE) and outcome expectations regarding exercise (OEE), physical fitness, activity level, physiological indices, and health-related quality of life in a sample of hemodialysis patients. Methods: A quasi-experimental control group pre-test post-test design was used. Subjects were recruited from two university hospitals in G city. The subjects were assigned randomly by coin toss: 33 participants to the experimental group and 30 to the control group. A literature review and the self-efficacy theory were used to develop the smartphone program. Experts designed and verified the program to be userfriendly and in consideration of user interaction. Data were collected through a self-report pre-test post-test questionnaire and online medical records. Results: In the experimental group, the levels of physical fitness and physical activity were significantly improved post-test, but the scores on health-related quality of life and the physical indices did not improve. In the experimental group, the SEE and OEE post-test scores were also significantly higher than the pre-test scores, but the control group's scores did not change. Conclusion: The smartphone application-based exercise program based on self-efficacy theory significantly improved the level of physical fitness and activity, SEE, and OEE for hemodialysis patients. The use of this application-based exercise program for hemodialysis patients might be an effective nursing intervention tool for improving SEE, OEE, level of physical fitness, and physical activity.

This study investigated the effect of nutritional improvement of 1-5 year children participated in NutriPlus program. The program was carried out at Public health Center, Daedeok-gu, Daejeon from March 2009 to April 2011. The subjects were selected among applicants for low-income family financing of the government and included 90 children and their parents. they were divided into 2 groups (less than 6 months and more than 6 months of participation in the study). We analyzed the effects of NutriPlus program and nutrition education in both study groups. The results of this study were summarized as follows: The number of children with less than 10th percentile in height and weight and weight for height was decreased. The anemia prevalence rate was reduced from 64.4% to 8.9%. NAR value of subjects increased for energy, protein, calcium, iron, vitamin A, riboflavin, niacin and vitamin C. The education program improved knowledge and attitude of the parents. In nutrition knowledge according to the income level, there were greater changes in the group of less than 100% compared to the subsistence. In nutrition attitude according to the education level, there were greater changes in the group of middle school graduates than in high school graduates or college graduates. There were no difference between less than 6 months group and more than 6 months group in improvement of hemoglobin level, anthropometric data and nutrients intakes. Based on these results, we conclude that providing supplementary food to children and nutrition education brought positive effects on growth of the children.

Sudden enhancements of daytime NmF2 appeared in Anyang ionosonde data during summer seasons in 2006-2007. In order to investigate the causes of this unusual enhancement, we compared Anyang NmF2's with the total electron contents (GPS TECs) observed at Daejeon, and also with ionosonde data at at mid-latitude stations. First, we found no similar increase in Daejeon GPS TEC when the sudden enhancements of Anyang NmF2 occurred. Second, we investigated NmF2's observed at other ionosonde stations that use the same ionosonde model and auto-scaling program as the Anyang ionosonde. We found similar enhancements of NmF2 at these ionosonde stations. Moreover, the analysis of ionograms from Athens and Rome showed that there were sporadic-E layers with high electron density during the enhancements in NmF2. The auto-scaling program (ARTIST 4.5) used seems to recognize sporadic-E layer echoes as a F2 layer trace, resulting in the erroneous critical frequency of F2 layer (foF2). Other versions of the ARTIST scaling program also seem to produce similar erroneous results. Therefore we conclude that the sudden enhancements of NmF2 in Anyang data were due to the misrecognition of sporadic-E echoes as a F-layer by the auto-scaling program. We also noticed that although the scaling program flagged confidence level (C-level) of an ionogram as uncertain when a sporadic-E layer occurs, it still automatically computed erroneous foF2's. Therefore one should check the confidence level before using long term ionosonde data that were produced by an auto-scaling program.

Objective: The purpose of this study is to find out the reliability and validity of the newly updated Balancia 2.5 program using Wii balance board through equipment that can measure center of pressure data with the precision. Design: Cross-sectional study Methods: Twenty-seven healthy adults participated in the study. The subjects were assessed for static balance ability by Accusway, and were assessed for static balance ability on Wii balance board connected to theBalancia 2.5 program.To limit postural fluctuations due to stare, the subjects were asked to look at a 15 cm dot drawn 3 m in front of them for 30 seconds with their eyes open. Static balance ability data such as path length and sway velocity were extracted from all measurement tools.Intra-rater and inter-rater reliability and validity were extracted through intraclass correlation coefficient (ICC) and 95% confidence interval (CI). Results: The intra-rater reliability that the same rater shows consistent results through test-retest was a high level at ICC=0.968 (0.926~0.986), and inter-rater reliability that the requires consistent results even when measured by different raters was a high level at ICC=0.943 (0.870~0.975). The validity was a high level at ICC=0.948 (0.881~0.977), which shows whether the measurement tool is properly measuring what it is intended to measure. Conclusions: The Balancia 2.5 program, newly updated through this study, proved to be a program with high reliability and validity in evaluating static balance ability like the existingBalancia 2.0 program.

A method for generation of design verification tests from behavior-level VHDL program is presented. Behavioral VHDL programs contain multiple communicating processes, signal assignment statements. So for large, complex system, it is difficult problem to test or simulation. In this paper, we proposed a new hardware design verification method. For this method generates control flow graph(CFG.) and process modeling graph(PMG) in the given under the testing VHDL program. And this method proved very effective that all the assumed design errors could be detected.

This study empirically studies the effects of Agricultural Technology Service Center's educational program for farmers on their incomes. The educational program for farmers has widely been managed in discourse and policy in Korea. In 2008, Agricultural Technology Service Center managed 88 educational program for farmers, where 6,409 farmers received a certificate. While there are important studies, most of them have concentrated on qualitative analysis and noneconomic effects to an educational program for farmers. This study tried to analyze whether or not there is an economic effect of an educational program for farmers, focusing on the relationship between the educational program for farmers and their income status. Multilevel models (or hierarchical linear models) were applied to this study. Multilevel model is a quantitative model of parameters that vary at more than one level and show hierarchical structures between levels. This study particularly accentuates that an educational program for farmers is more meaningful when it can raise farmers' incomes by region and by educational program for farmers.

The purpose of this study was to develop health promotion programs for middle aged women and to identify the adaptability and the effectiveness of the program in order to provide a model for health promotion programs as a basis for nursing intervention. The research design was a quasi-experimental, nonequivalent control-group pretest -posttest design. The data were collected from October 30 to December 11, 1996. The study subjects were middle aged women residing in Chonju city, with ages from 40 to 59. The experimental group consisted of 42 subjects who were recruited through announcements of the local newspaper. The control group consisted of 49 subjects who were mothers of nursing college students. The health promotion program for middle aged women was based on the Bandura's self efficacy theory and Pender's heath promotion behavior theory consisting of exercise and heath diaries as performance accomplishments as well as education and group sessions as verbal persuasion and vicarious experiences. The study program was provided for 6 weeks, 3 hours a day per week. There was a pretest before the program and a posttest after the 6 week program. The instruments used for the study were a Self Efficacy Scale and a Health Promotion Behavior Scale developed by Park(1995). The data analysis was done by the use of a SPSS/PC. The study results were as follows: 1. In the analysis of the homogeneity between the experimental and control groups, there were significant differences in the socio-demographic characteristics, self efficacy and health promotion behavior. There were significant differences between the experimental and control groups in occupation, the number of children, and the status of involvement in social activities. 2. The first hypothesis, 'The level of self efficacy of the experimental group will be higher than that of the control group.' was supported(F=10.154, p=.002). The second hypothesis, 'The degree of health promotive behaviors in the experimental group will be higher than that of the control group.' was supported(F=17.349, p=.000). 3. There was a significant positive correlation between the self efficacy and the health promotion behaviors in pretest and posttests (pretest: r=.732, p=.000 ; posttest : r=.754, p=.000). 4. The significant variables for health promotion behaviors were religion(t= -1.97, p=.05), family income(F=4.85, p=.00), education level (F=6.38, p=.00) and involvement in social activities(t= -3.06, p=.00) in socio-demographic characteristics. In summary, a heath promotion program based on self efficacy theory has made an improvement on health promotion behaviors. Also, the results show that the higher the level of self efficacy, the better the health promotion is in middle aged women. The study has proved that nurses can provide nursing intervention for the improvement of health promotion in middle aged women through the adaptation of a program increasing the subject's self efficacy level.

This study examined the characteristics of children, parents, family, and the extra context related to the parenting stress of employed and unemployed mothers from a broader perspective. The subjects were 323 employed mothers 3nd 300 unemployed mothers of pre-school age children. Parenting stress due to the role of being a parent for both employed and unemployed mothers was correlated with the chid's activity level, husband support, quality of life, available social support, and satisfaction of early childhood program's location. Parenting stress due to child-rearing of both employed and unemployed mothers was correlated with child's birth order, activity level and rhythmicity of child, husband support, quality of life, available social support, and satisfaction of early childhood program. Number of children was the strongest predictor of parenting stress due to the role of being a parent for employed mothers and the child's activity level for unemployed mothers. Besides, the child's activity level was the strongest predictor of parenting stress due to child-rearing for both employed and unemployed mothers.
