  • Purpose: This study was done to develop and test the effectiveness in late school-aged children of a healthy lifestyle education program for cancer prevention. Methods: Participants were 26 students in the sixth grade of N elementary school in J City (experimental group) and 25 students in the sixth grade of D elementary school with same educational conditions (control group). The research design was a nonequivalent control group pretest-posttest design. Data collection and execution of the study were carried out from March 10 to May 19, 2011. For the experimental treatment, 7 weekly sessions of the healthy lifestyle education program for cancer prevention were given by the researcher. Posttest was done immediately following the conclusion of the program and 4 weeks later. Frequencies, percentages, ${\chi}^2$-test, t-test, repeated measures ANOVA and paired t-test with SPSS WIN 18.0 were used to analyze the data. Results: Perceived barriers, perceived self-efficacy, activity related effect and family support significantly influenced cancer prevention knowledge and increases in healthy life styles. Conclusion: Results indicate that, as this program for cancer prevention was effective in increasing healthy lifestyle practices in these children, there is a need to further develop, test and implement programs in all schools.

  • Novel copper(II) complexes have been synthesized from the macrocyclic Schiff bases derived from Knoevenagel condensed ${\beta}$-ketoanilides (obtained by the condensation of acetoacetanilide and substituted benzaldehydes), 4-aminoantipyrine and ophenylene diamine. The structural features have been determined from their analytical and spectral data. All the Cu(II) complexes exhibit square planar geometry. Their high molar conductance values support their 1 : 2 electrolytic nature. The magnetic moment data provide evidence for the monomeric nature of the complexes. The X-band ESR spectra of the |$CuL^1$|$(OAc)_2$ in DMSO solution at 300 and 77 K were recorded and their salient features are reported. The in vitro biological screening effects of the investigated compounds were tested against the bacterial species Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Proteus vulgaris and Pseudomonas aeruginosa and fungal species Aspergillus niger, Rhizopus stolonifer, Aspergillus flavus, Rhizoctonia bataicola and Candida albicans by well diffusion method. A comparative study of inhibition values of the Schiff bases and their complexes indicate that complexes exhibit higher antimicrobial activity than the Schiff bases. Copper ions proved to be essential for the growth-inhibitor effect. The extent of inhibition appeared to be strongly dependent on the initial cell density and on the growth medium.

  • The human polyomavirus JC virus is the etiologic agent of progressive multifocal leukoencephalopathy (PML). As the JC virus early promoter directs cell-specific expression of the viral replication factor large T antigen, transcriptional regulation constitutes a major mechanism of glial tropism in PML. It has been demonstrated that SV4O or JC virus large T antigen interacts with p53 protein and regulates many viral and cellular genes. In this study we founts that p53 represses the JC virus early promoter in both glial and nonglial cells To identify the cis-regulatory elements responsible for p53-mediated repression, deletional and site-directed mutational analyses were performed . Deletion of the enhancer region diminished p53-mediated transcriptional repression. However, point mutations of several transcription factor binding sites in the basal promoter region did not produce any significant changes. In support of this observation, when the enhancer was fused to a heterologous promoter, p53 red reduced the promoter activity about three fold. These results indicate that the enhancer region is important for tole repression of JC virus transcription by p53. Furthermore, coexpression of JC virus T antigen with a p53 protein abolished p53-mediated repression of the JC virus early promoter in non-glial cells, but not in glial cells. This finding suggests that T antigen interacts with p53 and regulates JC virus transcription in a cell-specific manner.

  • During the past 20 years, a small but potentially powerful initiative has established itself in the mathematics education landscape: Mathematics Across the Curriculum (MAC). This curricular reform movement was designed to address a serious problem: Not only are students unable to demonstrate understanding of mathematical ideas and their applications, but also they harbor misconceptions about the meaning and purpose of mathematics. This paper chronicles the brief history of the MaC movement. The sections of the paper correspond loosely tn the typical steps one might take to solve a mathematics problem. The Problem Takes Shape presents a discussion of the social and economic forces that led to the need for increased articulation between mathematics and other fields in the American educational system. Understanding the Problem presents the potential value of exploiting these connections throughout the curriculum and the obstacles such action might encounter. Devising a Plan provides an overview of the support systems provided to early MAC initiatives by government and professional organizations. Implementing the Plan contains a brief description of early collegiate programs, their approaches and their differences. Extending the Solution details the adoption of MAC principles to the K-12 sector and throughout the world. The paper concludes with Retrospective, a brief discussion of lessons learned and possible next steps.

  • Siah acts as an E3 ubiquitin ligase that binds proteins destined for degradation. Extensive homology between siah and Drosophila Siah homologue (sina) suggests their important physiological roles during embryonic development. However, detailed functional studies of Siah in vertebrate development have not been carried out. Here we report that Siah2 specifically augments nodal related gene expression in marginal blastomeres at late blastula through early gastrula stages of zebrafish embryos. Siah2 dependent Nodal signaling augmentation is confirmed by cell-based reporter gene assays using 293T cells and 3TP-luciferase reporter plasmid. We also established a molecular hierarchy of Siah as a upstream regulator of FoxH1/Fast1 transcriptional factor in Nodal signaling. Elevated expression of nodal related genes by overexpression of Siah2 was enough to override the inhibitory effects of atv and lft2 on the Nodal signaling. In particular, E3 ubiquitin ligase activity of Siah2 is critical to limit the duration and/or magnitude of Nodal signaling. Additionally, since the embryos injected with Siah morpholinos mimicked the atv overexpression phenotype at least in part, our data support a model in which Siah is involved in mesendoderm patterning via modulating Nodal signaling.

  • Objectives: The purpose of this study was to identify the health promotion activities of the elderly Korean aged 65 or older and to examine the related factors associated with the health promotion activities. Methods: Data were obtained from 2008 Social Statistics Survey of Korea National Statistical Office of 6,207 people aged 65 or older. We measured the socio-demographic characteristics, physical health status, social health status, and health promotion activities. Statistical analyses were employed through the $X^2$-test and Odds ratio using Logit Model. Results: In our study, health promotion activity practice rates were varied among the socio-demographic characteristics, physical and social health status. Our findings also support that better socio-demographic and physical health status explain the higher practice rates of health promotion activities. In addition, the higher social health status was associated with better practice rates of health promotion activities. Conclusion: We found that the health promotion activities of the elderly could be encouraged by better socio-demographic status and physical and social health status. To better accomplish the health promotion for the elderly in our community, policy-makers should need careful political deliberation for executing health promotion services considering the distinctions of programme and target groups.

  • Objectives: This study intended to examine the influence of social capital and health behaviors on self-rated health in Korea. Methods: The data of the social statistics survey that the Korea National Statistical Office conducted in 2006 were chosen and 36,266 people from them, who were 30~59 years old were sampled. This paper made logistic regression analysis to examine the effect of social capital and health behaviors on self-rated health. Results: Odds ratios of social capital are family structure(1.321), marriage(1.214), satisfaction with family relationship(2.207), reliability of institutions(1.307), economic support(1.199), citizen's participation(1.531), and religious activity(1.138). Odds ratios of health behaviors are meal(1.431), exercise(1.356), and no drinking(0.648). Conclusion: Based on the results, this paper can suggest that the plan of keeping and building up social capital should be considered in the whole aspects of the society and the project of moderation in drink is required to consider social culture more.

  • The Consumer Education is one of the rapidly raised problems in the process of recent Economic Growth. As the Society and its economy changes into Oligopoly, the nature and the scope of the Consumer Education also changes. However, We don't have an institutional, systematic education of consumers. Even the basic concepts of Consumer Education has not yet been established, because it is in an infant state. Thus, the aim of this paper is to establish the fundermental concepts of Consumer Education and to help settlement of the direction of Consumer Education. The conclusions are as following: First, Consumers as the objects of Consumer Education are limited to the Ultimate-Consumer; and they can divided into three groups-Individual Consumer, Consumer-Group, the Consuming Masses. Now were have to deal with not only the concept of Ultimate Consumer which limited to the Consumer, but deal with the realistic problems involving Citizens and Livers. Second, Consumer Education is systematic educational activity in order that Consumers can assume an subjective behavior for the purpose of improvement and support of their own rights in society. Third, Consumer Education which enforced Consumers' Cooperative Society and Goods Test is the movements of systematic resistance of consumers. The former aims at Economic Equilibrium, while the latter Informative Equilibrium. so, the two movements should channel the direction of Consumer Education in order to realize the Equilibrium.
