Purpose: This study aimed to identify the prevalence of alcohol and cigarette use and assess its relationship with socio-environmental, psychological, violent and behavioral factors among a sample of high school students from Lima and Callao, Peru. Methods: We utilized the data from a cross-sectional study conducted by the Yonsei Global Health Center in collaboration with the Korea International Cooperation Agency (KOICA) Peru office in November 2016. The total sample size of this study was 1,477 students. For analysis, we used bivariate and multivariate logistic regression to calculate the unadjusted and adjusted odds ratios and their respective 95% confidence intervals. Results: The current prevalence of alcohol and cigarette use among adolescents was found to be 24.2% and 12.1%, respectively. Alcohol use was affected by age, friends' alcohol use, experience of physical fighting, and involvement in other risk behaviors (smoking, drug use, and sexual intercourse). Cigarette use was affected by perceived academic performance, friends' cigarette use, and involvement in other risk behaviors (drinking, drug use, and sexual intercourse). Furthermore, students who received affection from their parents and whose parents monitored their activities were less likely to report using both alcohol and cigarettes. Conclusion: Alcohol and cigarette use among Lima and Callao adolescents is affected by socio-environmental, violent and behavioral factors. Alcohol and cigarette use prevention initiatives should promote positive parenting practices, family togetherness, and a supportive school climate. In addition, it is needed to establish peer-led programs that promote behavioral changes in students and strengthen social relations without the presence of alcohol, cigarettes, and other harmful substances.

Purpose: This study was conducted to evaluate the effect of a one-session spouse-support enhancement childbirth education on childbirth selfcefficacy and perception of childbirth experience. Methods: The design of this study was a nonequivalent control group pretest-posttest experiment. The participants in the study were 31 couples in the experimental group and 30 in the control group. The experimental couples were provided with one session on spouse-support enhancement childbirth education the night before delivery. Data were collected at two hours after delivery using the Childbirth Self-Efficacy Inventory (CBSEI) and perception of childbirth experience scale. Data were analyzed using PASW statistics 18 program. Frequencies, percentage, mean, $x^2test$, t-test were used for data analysis. Results: Childbirth self-efficacy significantly increased in the experimental group as compared to the control group, but there was no significant difference in perception of childbirth experience in the experimental group compared to the control group. Conclusion: The results suggest that a one-session childbirth education has beneficial effects on enhancing childbirth self-efficacy in pregnant couples. A one-session spouse-support enhancement childbirth education is recommended as an effective nursing intervention to promote couple's childbirth self-efficacy and it is also recommended that modifications of program to promote women's childbirth experience should be considered.

As the most common type of endocrine malignancy, papillary thyroid cancer (PTC) accounts for 85-90% of all thyroid cancers. In this study, we presented the hypothesis that SDC4 gene silencing could effectively attenuate epithelial mesenchymal transition (EMT), and promote cell apoptosis via the $Wnt/{\beta}-catenin$ signaling pathway in human PTC cells. Bioinformatics methods were employed to screen the determined differential expression levels of SDC4 in PTC and adjacent normal samples. PTC tissues and adjacent normal tissues were prepared and their respective levels of SDC4 protein positive expression, in addition to the mRNA and protein levels of SDC4, $Wnt/{\beta}-catenin$ signaling pathway, EMT and apoptosis related genes were all detected accordingly. Flow cytometry was applied in order to detect cell cycle entry and apoptosis. Finally, analyses of PTC migration and invasion abilities were assessed by using a Transwell assay and scratch test. In PTC tissues, activated $Wnt/{\beta}-catenin$ signaling pathway, increased EMT and repressed cell apoptosis were determined. Moreover, the PTC K1 and TPC-1 cell lines exhibiting the highest SDC4 expression were selected for further experiments. In vitro experiments revealed that SDC4 gene silencing could suppress cell migration, invasion and EMT, while acting to promote the apoptosis of PTC cells by inhibiting the activation of the $Wnt/{\beta}-catenin$ signaling pathway. Besides, $si-{\beta}-catenin$ was observed to inhibit the promotion of PTC cell migration and invasion caused by SDC4 overexpression. Our study revealed that SDC4 gene silencing represses EMT, and enhances cell apoptosis by suppressing the activation of the $Wnt/{\beta}-catenin$ signaling pathway in human PTC.

Background: According to the previous studies, the work-related accident rate decreased in Korea after the introduction of occupational health and safety management system (OHSMS), but there were several disasters in Korea such as subway worker's death at Guui station in 2016 and the Taean thermal power plant accident in 2018, which escalated the social demand for safety. In 2018, OHSMS became an international standard, as ISO45001 was announced. Methods: A survey was conducted to research the implementation status of OHSMS and changes in people's perception, and the results were compared with those of a past survey. Results: Enhanced social demand and various stakeholders' (not only buyer) needs, and social responsibility are perceived as the motivation for the introduction of OHSMS rather than legal compliance or customer demand. In the questionnaire about problems with the implementation of OHSMS, the factors with higher response rate in 2018 than 2004 were "excessive cost" and "complicated documentation management." In the questionnaire about how to promote OHSMS in organizations, most people answered "reduction of workers' compensation insurance rate" in 2004, but most people answered "exemption from health and safety supervision" in 2018. Conclusion: For the effective implementation of ISO45001, emphasis is placed on social demand, training to recognize health and safety as a part of management, and the reduction of certification and consulting costs to promote the introduction of OHSMS. Incentives such as insurance premium cuts and exemptions from health and safety supervision are needed.

Background: Tracheal replacement is a challenge for thoracic surgeons due to stenosis in the trachea-prosthesis anastomosis. We propose that stenosis occurs due to fibrosis as a result of an abnormal healing process, characterized by an increased expression of wound healing growth factors (vascular endothelial growth factor [VEGF], survivin, and CD31), which promote angiogenesis and decrease apoptosis. We analyzed the immunoreactivity of VEGF, survivin, CD31, and caspase-3 in the development of fibrotic stenosis in prosthetic tracheal replacement. Methods: Fourteen dogs were operated on: group I (n=7) received a 6-ring cervical tracheal segment autograft, while in group II (n=7), a 6-ring segment of the cervical trachea was resected and tracheal continuity was restored with a Dacron prosthesis. The follow-up was 3 months. Immunoreactivity studies for VEGF, survivin, CD31, and caspase-3 were performed. A statistical analysis was done using the Wilcoxon signed rank test. Results: Four animals in group I were euthanized on the 10th postoperative day due to autograft necrosis. Three animals completed the study without anastomotic stenosis. Moderate expression of VEGF (p=0.038), survivin (p=0.038), and CD31 (p=0.038) was found. All group II animals developed stenosis in the trachea-prosthesis anastomotic sites. Microscopy showed abundant collagen and neovascularization vessels. Statistically significant immunoreactive expression of VEGF (p=0.015), survivin (p=0.017), and CD31 (p=0.011) was observed. No expression of caspase-3 was found. Conclusion: We found a strong correlation between fibrosis in trachea-prosthesis anastomoses and excessive angiogenesis, moderate to intense VEGF, CD31, and survivin expression, and null apoptotic activity. These factors led to uncontrolled collagen production.

The purpose of this research is to promote the academic achievement motivation and improve problem solving ability in Mathematics. In addition I hope to explore a new teaching method and facilitate students interest in mathmatics. If the teachers utilize an Internet Web Page and exchang information, the interaction activities will allow them to collect and analyse a variety of data. As this teaching method assists students motivation to get the effects of self-regulated learning strategies of students using the internet and their academic achievements and learning attitudes can be explored. The information will be gathered after the students participate in classes which were taught through the Edunet Homepage and the Department of Mathematics Homepage of KongJu National University. The Internet pages focused on the "Function" chapter of the first grade text for students attending middle school. The students were divided into two groups, experimental and comparative. Each group is composed of three levels, high, middle, and low. In the post experimental phase, two tests were administered which measured achievement ability and the learning attitude of the students. The results of the tests were then compared and analyzed. The results were as follows: First, the study demonstrated that self-regulated Learning Starategies towards Academic Achievements and Learning Attitudes were more effective than traditional teaching methods. These methods were significantly effective in the middle level and low level groups. The study demonstrated little to no improvement in the high level groups
