  • The subjects of this study were 4th to 6th grade children and instruments were the Teenage Inventory of Social Skills, the Internal-External Control Scale, the Self-Esteem Scale, and the Peer Relations Questionnaire. In the concurrent study, children lower in social skills and in self-esteem and external in locus of control reported more bullying and victimization. Children higher in social skills and in self-esteem and internal in locus of control reported more prosocial behavior. In the prospective study, children lower in social skills were more involved in bullying and victimization. Children higher in social skills reported more prosocial behavior. The effects of locus of control and self-esteem on peer relations diminished over time. However, social skills had a significant influence on bullying, victimization and prosocial behavior up to two years later. Children lower in psychosocial development were more vulnerable to peer victimization.

  • Objective: To evaluate the relationship between allium vegetable intake and risk of prostate cancer. Methods: A systematic literature search up to May 2013 was carried out in PubMed, EMBASE, Scopus, Web of Science, Cochrane register, and Chinese National Knowledge Infrastructure (CNKI) databases, and the references of retrieved articles were also screened. The summary relative risks with 95% confidence interval for the highest versus the lowest intake of allium vegetables were calculated. Heterogeneity and publication bias were also evaluated. Results: A total of nine epidemiological studies consisting of six case-control and three prospective cohort studies were included. We found a significantly decreased risk of prostate cancer for intake of allium vegetables (OR=0.82, 95% CI 0.70, 0.97). Moreover, in the subgroup analysis stratified by allium vegetable types, significant associations were observed for garlic (OR=0.77, 95% CI 0.64-0.91) but not onions (OR=0.84, 95% CI 0.62-1.13). Conclusions: Allium vegetables, especially garlic intake, are related to decreased risk of prostate cancer. Because of the limited number of studies, further well-designed prospective studies are warranted to confirm the findings of our study.

  • Background: Epidemiological findings are controversial relating to the relationship between dietary folate intake and the risk of breast cancer. We therefore conducted a meta-analysis of prospective cohort studies to clarify this association. Materials and Methods: PUBMED, EMBASE, and MEDLINE databases were searched for all relevant literature published in English from January 1, 1966 to August 2013. Summary relative risk (RR) and 95% confidence intervals (CIs) were calculated using a fixed or random effects model. Results: Dietary folate intake was not significantly associated with the risk of breast cancer. The combined RR with 95%CI for the highest vs. lowest category dietary intake of folate [fifteen studies; 1,836,566 participants and 24,083 patients with breast cancer] was 0.98 (0.90-1.05). Among subgroup analysis by menstrual status, hormonal status and the consumption of alcohol, methionine and vitamin B12, no significant association was observed for the dietary intake of folate and the risk of breast cancer. Dose-response analysis showed that a 220 ${\mu}g/day$ increment in dietary folate intake was not associated with the risk of breast cancer. Conclusions: Our findings indicate that dietary folate intake has no significant effect on the risk of breast cancer.

  • The purpose of the study was to explore what factors influenced the elderly's prospective inheritance types such as traditional, equal, practical, and non-inheriting type. The role of older parents' socio-demographic and intergenerational characteristics affecting a decision on each pattern was paid special attention to. I used the nationally representative data from 10,469 older parents living independently in the '2008 Korean National Survey of Welfare Need in the Elderly'. Results showed that prospective inheritance types among the elderly were diverse. The type which pursues equal distribution of wealth to all the children emerges predominantly from them. Findings also suggested that inheritance types were associated with factors such as both individual and intergenerational variables. Furthermore, different factors had different impact on each type. Individual variables contributed more to equal types while intergenerational variables contributed to practical types. More interestingly, both individual and intergenerational factors affected non-inheriting types. Further research is necessary to investigate what mechanisms will be operating through the process of inheritance, which social policies will be substituted for the inheritance, and what other variables will account for the intergenerational transmission of wealth.

  • 본 연구의 목적은 활동 이론의 관점에서 초등학교 예비교사인 김교사가 실시한 수학 수업을 탐색하는 것이다. 본 연구에서는 $Engestr{\ddot{o}}m$이 제안한 활동 이론(Activity theory)과 활동체계(Activity system)의 주요 개념인 주체, 목표, 도구, 공동체, 분업, 규칙의 측면에서 수학 수업과 수학 수업에서 나타난 현상을 살펴보았다. 본 연구의 결과로서, 활동체계로서의 김교사의 수학 수업에서 목표와 도구의 동요, 목표-규칙-결과-학생 주체 사이에서 발생하는 '다층-목소리'와 갈등, 분업-공동체-규칙 사이에 내재하는 불협화음 등의 현상이 발생함을 논의하였다. 또한, 본 연구에서는 김교사의 수업에서 수학과 교육과정의 강조점인 조작 교구를 활용한 수학 원리의 이해가 활동체계의 규칙으로 작용함을 확인했으며, 이러한 규칙이 수학 수업에서 구현되기 위해서는 공동체의 노력과 정책적 지원이 필요함을 제안하였다.

  • Backgrounds/Aims: Pancreaticoduodenectomy (PD) is commonly performed pancreatic procedure for tumors of periampullary region. Delayed gastric emptying (DGE) and pancreatic fistula are the most common specific complications following PD. DGE can lead to significant morbidity, resulting in prolonged hospital stay and increased cost. Various factors might influence the occurrence of DGE. We hypothesized that kinking of jejunal limb could be a cause of DGE post PD. Methods: Antecolic (AC) and retrocolic (RC) side-to-side gastrojejunostomy (GJ) groups in classical PD were compared for the occurrence of DGE in a prospective study. All patients who underwent PD between April 2019 and September 2020 in a tertiary care center in south India were included in this study. Results: After classic PD, RC GJ was found to be superior to AC in terms of DGE rate (26.7% vs. 71.9%) and hospital stay (9 days vs. 11 days). Conclusions: Route of reconstruction of GJ can influence the occurrence of DGE as RC anastomosis in classical PD provides the most straight route for gastric emptying.

  • In K-12 education, reassessment is a common practice, providing students with opportunities to enhance their understanding through low-stakes assignments. However, reassessment is underutilized in higher education, including during the challenges posed by the COVID-19 pandemic. Our study advocates for expanding the use of reassessment in university settings to promote holistic learning and focus on what shifts of change were made by students in an initial mathematics content course as they sought to gain licensure for teaching in a birth (daycare/pre-K setting) to eighth-grade classrooms. Our study took place during COVID-19 semesters and aimed to examine how using a reassessment approach early on in a gateway course for Prospective Teachers (PTs) affected the pass rate of the course. Results showed significant differences between the PTs who engaged with the test recovery and those who did not. We propose recovery opportunities like ours provide the necessary guidance to support early degree necessary classes that are typically gatekeeping and, as another, likely cause too few students within the courses because they were able to advance into the teacher pipeline and out into the field. Future studies may consider how the reassessment could be done more before the official summative assessment of a unit or chapter to continue the shifts in teaching practices and pedagogy that are constant within the K-12 education systems at the university level.
