This study examined the beneficial effects of the science experiment program for Low-Income Family Children (LIFC) on their science attitude, self-esteem, self-competence, and creativity. The study involved 432 elementary school children of Low-Income Family who were divided two groups as an experimental group with 228 and a control group with 204. The experimental group was given by the science experimental program, whereas the control group was given by ordinary education programs for LIFC, such as supplementary education or after school care. The data about science attitude, creativity, self-esteem, and self-competence of two group children's were collected and analyzed by four kinds of tests on each domain before and after implementing the science experiment program. During the period of the science experiment program, the children who were given the program were observed and reported by the program lecturers and the teachers, who worked at the after school care. The results are as follows; First, there was statistically significant increase on the average points of the experimental group on the three domains except self-esteem from the intra-group analysis. Second, there was also statistically significance between the scores of two groups on the creativity, self-esteem, self-competence from the inter-group analysis. Third, it was reported that the children who were experienced the program were changed positive on their personality and school learning.

Purpose - Economic status at an early stage of life after one's retirement is often determined by the long-term sacrifice of one's earlier consumption tendencies. In general, the first and foremost way to secure income after retirement is through annuity savings. People sign up for personal annuity savings in order to guarantee a stable economic life upon retirement, and such actions may be heavily influenced by self-efficacy. Confidence in current economic activity is a source of rational decision-making. Inability to achieve self-control can lead to reckless spending and the eventual hindering of proper investment for the future. This paper examines how self-efficacy and self-control affect the intention and action of enrolling in an annuity savings plan in relation to one's level of financial literacy. Research design, data, and methodology - To analyze the proposed model, this study investigates financial consumers over the age of 20. The data were collected from 511 respondents and analyzed with SPSS 21.0 and AMOS 21.0. First, for the one-dimensional test and to measure the convergent validity of each structure, we use the scale purification process. The results of the test and the confirmatory factor analysis ensure the focus of the validity of the single dimension for each structure. In addition, the validity of the measurement was guaranteed from the results of correlation analysis. Results - First, self-efficacy and self-control have positive effects on the purchasing intention of the personal annuity savings plan. Second, purchasing intention positively affects purchasing behavior. Lastly, self-control has a positive effect on purchasing intention among the low financial literacy group, whereas self-efficacy does not have this effect in the high financial literacy one. Conclusions - The time of product benefit is different with age. The younger group would be granted the savings after several decades once they enroll, whereas the older group would wait for a relatively shorter period of time. Therefore, further research should be conducted in order to verify such a difference. However, this study has value through its confirmation that the roles of self-efficacy and self-control play a part in leading to the enrollment in annuity savings plans and by verifying different effects based on levels of financial literacy. Such results suggest a number of implications in a real life setting. First, banks need to put greater emphasis on the stability of annuity savings in general. Second, customers with relatively low levels of financial literacy are able to control their finances through annuity savings, but find self-efficacy difficult due to a lack of financial understanding. Therefore, such customers should be approached from an invest-effectiveness comparison method. Third, customers with high financial literacy tend to put more value in rational economic decision-making and behavior than in self-efficacy. Therefore, such customers should be approached by promoting the reliability of annuity savings and the excellence of the specific bank's annuity savings plan in comparison to those of other financial institutions.

Purpose: The purpose of this study was to identify the effect of exercise therapy on low back pain, self-urination disorder, bleeding, and hematoma in Percutaneous Coronary Intervention (PCI) patients. Methods: A total of 64 PCI patients were recruited from C hospital located in C city, from June until August of 2010. The patients were divided into two groups as the exercise and control group. Thirty-two participants in the exercise group took bedrest for two hours after PCI, and then received excise therapy. The other 32 participants in the control group took the usual 8-hour bedrest with intermittent back care by the unit nurses. Results: In the relieving effect of low back pain, exercise group reported pain reduced faster than the control group. On the other hand, there were no significant differences between the two groups in alleviant of self-urination disorder, bleeding, and hematoma. Conclusion: Exercise therapy for reducing patients' low back pain showed to be an effective nursing intervention. Since there was no bleeding or hematoma after PCI in the exercise group, this study provided the ground suggesting that it might be possible to reduce the bedrest time after PCI without increased risk of bleeding or hematoma.

Using survey data collected from 275 adolescent children of widowed or divorced single mother families, this study investigated the characteristics of family coping resources, including individual, financial, social, and mother-child relational resources and their effects on the psychological wellbeing of these adolescents. After controlling background variables of the family, higher depression among adolescents was associated with low grade point average, mother's high exposure to negative experiences after loss of father, low attachment to mother, and low sense of self-control. Furthermore, higher grade point average, strong attachment to mother, and high self-control in problem solving were factors predicting higher self-esteem of adolescents. Social network resources were not related to the psychological well-being of the adolescents. Discussion included recommendations for future research. Implications for policy and parent-child relations were discussed with a view to enhancing family functioning of adolescents in single-mother families.
