The purpose of this study is to examine the causal relationship between self-efficacy and safety consciousness of health belief factors and how they affect the disaster prevention behavior of construction workers using TBM. To this end, a research model is presented that applies the main variables of the Health Belief Theory, a social psychological health behavior change model developed to predict and explain health-related behaviors. To empirically verify the research model of this study, a survey was conducted among construction workers who have experience in using TBMs for chemical plant construction. The results showed that, first, the perceived severity of construction workers utilizing chemical plant construction has a significant effect on self-efficacy and safety consciousness; second, the perceived probability of construction workers utilizing chemical plant construction has a significant effect on self-efficacy and safety consciousness. Third, the perceived obstacles of construction workers utilizing chemical plant construction have a significant effect on self-efficacy and safety consciousness. Fourth, the perceived benefits of construction workers utilizing chemical plant construction were found to have a significant effect on self-efficacy and safety awareness. The purpose of this study is to reduce critical accidents through disaster prevention behavior of chemical plant construction workers through TBM.

The object of this study was to analyze factors influencing adult dementia knowledge, fear of dementia, and intention of dementia prevention behavior on the demand for dementia prevention education. The subjects of the study were 265 adults aged 19 to 64 living in Chungnam and Chungbuk, who understood the purpose of the study and agreed to participate in the study. The collected research data were analyzed using frequency, percentage, mean, standard deviation, t-test, ANOVA, and multiple regression analysis. As a result of the study, adult dementia knowledge (p=.055) and dementia fear (p=.302) were found that they did not significantly affect the demand for dementia prevention education, and the intention of dementia prevention behavior (β=.329, p<.001) was found to have a significant effect on the demand for dementia prevention education. Based on these research results, understanding of dementia and dementia management projects, early screening for dementia and health guidelines for dementia prevention, chronic disease management for dementia prevention, exercise for dementia prevention, healthy eating for dementia prevention, and cognitive enhancement for dementia prevention In addition to the national dementia prevention publicity and national response efforts such as programs, it is necessary to actively participate in the dementia prevention program centered on the community to practice the correct dementia prevention behavior and provide sufficient opportunities to prevent it.

Obesity is an established risk factor for colorectal cancer. Pioglitazone is a peroxisome proliferator activated receptor$receptor{\gamma}$ ($PPAR{\gamma}$) agonist that induces differentiation in adipocytes and induces growth arrest and/or apoptosis in vitro in several cancer cell lines. In the present study, we investigated the effect of pioglitazone on the development of azoxymethane-induced colon aberrant crypt foci (ACF) in KK-$A^{\mathcal{Y}}$ obesity and diabetes model mice, and tried to clarify mechanisms by which the $PPAR{\gamma}$ ligand inhibits ACF development. Administration of 800 ppm pioglitazone reduced the number of colon ACF/mouse to 30% of those in untreated mice and improved hypertrophic changes of adipocytes in KK-$A^{\mathcal{Y}}$ mice with significant reduction of serum triglyceride and insulin levels. Moreover, mRNA levels of adipocytokines, such as leptin, monocyte chemoattractant protein-1 and plasminogen activator inhibitor-1, in the visceral fat were decreased. PCNA immunohistochemistry revealed that pioglitazone treatment suppressed cell proliferation in the colorectal epithelium with elevation of p27 and p53 gene expression. These results suggest that pioglitazone prevented obesity-associated colon carcinogenesis through improvement of dysregulated adipocytokine levels and high serum levels of triglyceride and insulin, and increase of p27 and p53 mRNA levels in the colorectal mucosa. These data indicate that pioglitazone warrants attention as a potential chemopreventive agent against obesity-associated colorectal cancer.

Isoflavones are phytoestrogens and natural plant compounds which are similar to 17-${\beta}$-estradiol in chemical structure. It is known that they can act as estrogen agonists or antagonists, depending on endocrine estrogenic levels, but actions of isoflavones are rather complex due to large number of variables such as chemical structures and mechanisms. Some hypotheses on biological mechanisms have not satisfactorily been confirmed to date and human epidemiological and experimental studies have been relatively limited. Nevertheless, isoflavones and isoflavone rich foods have become a focus onf interest due to positive health benefits on many diseases, especially prevention of hormone-related cancers, cardiovascular disease, osteoporosis, and adverse postmenopausal symptoms, and improvement of physiological condition such as maintaining cognitive function. This review provides an overview of chemistry, analytical techniques (focused on human biospecimens), functions including biological mechanisms, and effects of isoflavones, on the basis of the available meta-analysis and review articles and some original articles, on health and cancer.

This paper introduces models for preventive maintenance policies and considers periodic preventive maintenance policy with minimal repair when the failure of system occurs. It is assumed that minimal repairs do not change the failure rate of the system. The failure rate under prevention maintenance received an effect by a previously prevention maintenance and the slope of failure rate increases the model where it considered. Also the start point of failure rate under prevention maintenance considers the degradation of system and that it increases quotient, it assumed. Per unit time it bought an expectation cost from under this prevention maintenance policy. We obtain the optimal periodic time and the number for the periodic preventive maintenance by using Nakagawa's Algorithm, which minimizes the expected cost per unit time.

Purpose: This study was done to conduct a meta-analysis of articles describing randomized controlled trials which showed substantiated effects for home-based child abuse prevention programs for all parents. Methods: The articles regarding child abuse prevention programs for parents were investigated using the systematic review method. A literature search was conducted in PubMed, CINAHL, PsycINFO, Cochrane central library, Eric, and RISS on material published. Article searches and quality appraisal through RoB (Risk of Bias) yielded 14 records. Results: The total random effect size was 0.344 (Parents outcome, 0.333; Child outcome, 0.310; Environment, 0.275). The home based intervention for parents was effective for prevention of potential child abuse. Conclusion: This study supports the effectiveness of health care professional directing child abuse prevention programs for all parents whose children are in the early years of life including during the period of pregnancy.

This study compared the effectiveness of various prevention methods(1-time video viewing; repeated video viewing; participation-enriched video viewing) used in delivering awareness of sexual abuse and coping skills to preschool children. All of the experimental groups performed better than the control group. The participation-enriched viewing group displayed higher levels of coping skills than the control and the 1-time viewing groups. Repeated viewing and participation-enriched viewing approaches were most effective in long-term understanding. The repeated viewing group showed superiority in long-term coping skills. Direct participation, interaction, and reinforcement by means of repetition are important for optimal results in sexual abuse prevention education.

The effectiveness of sodium carboxymethylcellulose(SCMC) and dextran 70 in the prevention of adhesion formation in abdominal cavity of rabbits following artificial injuries was elucidated and the effects -of these medicines on blood pictures were also examined. After abrasion treatment on jejunum in gonadotropins primed rabbits, 1, 2 and 3% of SCMC solutions, 6 and 10% dextran 70 solutions and a synthetic solution of 1% SCMC and loft dextran 70 in 0.9% saline solution were infused into the abdominal cavity. Four weeks later the abdominal cavities were reopened under general anesthesia. The synthetic solution showed the highest adhesion reduction rate(100%), while 1% SCMC, 6 and loft dextran solutions showed no significantly evident effect of adhesion prevention. The SCMC solutions showed better adhesion reduction effect than dextran 70 solutions. After infusion of these adhesion preventive medicines, the changes of total leucocytes, erythrocytes, lymphocytes, PCV, plasma fibrinogen and protein contents were examined. No remarkable difference in blood pictures was shown between the synthetic solution and the other medicines. Therefore, it can be suggested that the synthetic solution of 1% SCMC and 10% dextran 70 in 0.9% saline solution at dose of 5$m\ell$/kg of body weight is prominently effective in the prevention of postoperative adhesion formation and wolf be safe in animals and human.
