Objective: To investigate the association between the gene polymorphisms of angiotensin-converting enzyme (ACE) and digestive system cancer risk. Method: A search was performed in Pubmed, Medline, ISI Web of Science and Chinese Biomedical (CBM) databases, covering all studies until Sep 1st, 2013. Statistical analysis was performed by using Revman5.2 and STATA 12.0. Results: A total of 15 case-control studies comprising 2,390 digestive system cancer patients and 9,706 controls were identified. No significant association was found between the I/D polymorphism and digestive cancer risk (OR=0.93, 95%CI = (0.75, 1.16), P=0.53 for DD+DI vs. II). In the subgroup analysis by ethnicity and cancer type, no significant associations were found for the comparison of DD+DI vs. II. Results from other comparative genetic models also indicated a lack of associations between this polymorphism and digestive system cancer risks. Conclusions: This meta-analysis suggested that the ACE D/I polymorphism might not contribute to the risk of digestive system cancer.

Purpose: This study examined the impact factors of cesarean section based on the ecological approach in Korea. Methods: Population-based data (Korea Institute for Health and Social Affairs) were used from 2,849 delivery cases during 2003~2009. Data were analyzed using geographic statistics with STATA 10.0 and hierarchical logistic regression with SPSS/WIN 12.0. Results: The range of cesarean section rate was 28.8~44.7% with geographic distribution. The proportion of mother's problem was increasing in choice of cesarean section. According to the ecological model, age of mother (OR=1.08), time of birth (OR=0.79), delivery in hospital (OR=1.83), delivery in clinic (OR=1.46), and education of mother (OR=2.61) had significant impact on cesarean section. Conclusion: This study contributes to provide the impact factors of the high cesarean rate in Korea ecologically. Policy maker and health care provider can consider these results to reduce cesarean section rate.

In order to explore the association between cadherin 13 (CDH13) gene promoter methylation and lung carcinoma (LC) risk, we carried out a meta-analysis with searching of PubMed, Web of Science. Ultimately, 17 articles were identified and analysised by STATA 12.0 software. Overall, we found a significant relationship between CDH13 promoter methylation and LC risk (odds ratio=6.98, 95% confidence interval: 4.21-11.56, p<0.001). Subgroup analyses further revealed that LC risk was increased for individuals carrying the methylated CDH13 compared with those with unmethylated CDH13. Hence, our study identified a strong association between CDH13 gene promoter methylation and LC and highlighted a promising potential for CDH13 methylation in LC risk prediction.

선박의 운항분포는 교량충돌확률이나 선박충돌위험도 등을 계산할 때 매우 중요한 요인으로 작용하지만, AASHTO모델이나 해상교통안전진단에서의 근접도 평가모델 등 많은 충돌 또는 위험도 계산 모델에서는 선박의 운항분포가 단순한 정규분포임을 가정하고 있다. 따라서 특정 항로나 해역에서의 정확한 충돌, 위험 또는 안전 등에 관한 확률을 구하고자 할 경우에는 그 항로나 해역의 특성에 맞는 선박 운항분포를 사용해야 한다. 이 연구에서는 일주일간의 통항선박 위치정보(AIS정보)를 이용하여 다양한 특성을 가지는 항로별로 각각 고유한 특성의 선박 운항분포를 찾아내기 위해, sech 함수를 이용한 새로운 충돌위험도 평가법에서 피항구역의 문턱값을 결정하는 방법을 분석하고 실제 상황에 적용 가능한 식을 개발하였다.

Background: While many studies have concluded that local traffic density is positively associated with childhood leukemia, the results are inconsistent. We therefore performed a meta-analysis to assess the relationship between traffic density and the risk of childhood leukemia. Methods: A systematic literature review was carried out using PubMed, EMBASE, and the Cochrane Library from January 1979 to December 2013. We selected and assessed journal articles evaluating the relationship between local traffic density and the risk of leukemia in children. The analysis was carried out using STATA version 12.0. Results: A total of 11 articles, including 12 estimates of effect, were included in our meta-analysis. The summary effect size from the random-effects model, expressed as an odds ratio, was 1.03 (95% CI: 0.98-1.09, p=0.002). No significant association between traffic density and the risk of childhood leukemia was found. Similar conclusions were found on subgroup analysis. Conclusions: The results of our meta-analysis suggested no association between traffic density and the risk of childhood leukemia. This implies that living in close proximity to roads with heavy traffic may not increase the risk of childhood leukemia. However, further high-quality prospective trials are needed to support these results.

1. The effects of different conditions of the feedings in connection with the bottom stata on the growth rate of Penaeus orientalis have been investigated. 2. The relationships between the days (D) after hatching and the carapace lengths (L) of p. orientalis are represented by the following equations: Feeding, muddy bottom: L=0.3939D+6.8965 feeding, sandy bottom: L=0.2652D+12.2620 Nonfeeding, sandy bottom: L=0.0713D+16.0655 Nonfeeding, muddy bottom: L=0.2852D+7.8620 3. The growth rate of the carapace length of p. orientalis in the region of muddy bottom is higher than that of the carapace in the sandy bottom whether the prawns are fed or not.

An economic system is a means by which societies or governments organize and distribute available resources, services, and goods across a geographic region or country. The Islamic financial system faces a number of challenges as part of its role as a tool for developing economic activities. This study intends to advance research by Lassoued (2018) by expanding the research population to include Islamic banks in Asia and adding new dimensions - the size of the independent commissioner and corporate governance. The population of this study is the 100 largest Islamic banks in Asia. Statistical calculations with the STATA application is used for data analysis. Based on the test results, it was found that the size of the sharia board and the independent board of directors did not affect the financial stability of Islamic banking companies. Another finding is that the size of the independent commissioner affects financial stability. This finding shows that commissioners have played an active role in the company, indicating that if the sharia banking company has an ideal number of independent commissioners, it will be advantageous to the company's stability and business sustainability.

Purpose: The purpose of this study was to analysis the effects of nasal Continuous Postive Airway Pressure (nCPAP) for preterm infants using systematic review and meta-analysis. Methods: Thirteen peer-reviewed journals including preterm infants and apnea and nCPAP published between 1973 and 2013 were included. Effect size and statistics of homogeneity were done using STATA 10.0. Results: The design for 9 studies was Randomized Control Trial. In most of studies the pressure of nCPAP was set to 4-6 cm$H_2O$. The effect size of 5 studies for the effect on apnea rate using nCPAP compared to nasal Intermittent Positive Pressure Ventilator (nIPPV) showed that the Standardized Mean Difference (SMD) was -0.11 and was not significantly different (Z=0.41, p=.680). But the difference in nCPAP for nasal Synchronizes Intermittent Positive Pressure Ventilator (nSIPPV) (subgroup) was significant (SMD=-.44). The effect size of 7 studies on effect for ventilator weaning of using nCPAP compared to nIPPV showed the Risk Ratio (RR) as 1.60 and was not significantly different (Z=1.12, p=.268). But the difference between nCPAP and nSIPPV (subgroup) was significant (RR=3.94). Conclusion: The results indicate a need for an advanced care system and suggest continuous studies of apnea in preterm infants.

The purpose of this study was to grasp the benefits from pit and fissure sealants and to analyze the factors of influencing the benefit amount by using the raw data of the Korea National Health and Nutrition Examination Survey for 2007~2013 targeting the subjects aged from 6 years in full to 18 years. The analysis was used STATA 11.0. As a result of the analysis, the following conclusions were obtained. It rose up to 1.24 pieces after carrying out the national health insurance coverage from averagely 0.93 piece until the year in 2007~2009 (up to November) when is before enforcing the national health insurance coverage in the pit and fissure sealants. The benefits from pit and fissure sealants depending on general characteristics were surveyed to be higher in the higher income level, in the more subscription to health insurance and private insurance, and in the more toothbrushing frequency per day. The factors that have influence upon the benefits from pit and fissure sealants were shown to include whether or not to have the national health insurance coverage in the pit and fissure sealants, income level, health insurance type and private insurance subscription appearance, and one-day toothbrushing frequency. Synthesizing the results, a rise in the benefits from pit and fissure sealants is shown in 2010 based on December 2009 when the national health insurance coverage in the pit and fissure sealants was implemented, but is showing the tendency of declining again from 2011. To increase the benefits from pit and fissure sealants, it is thought that the schemes will need to be discussed such as reinforcing publicity on the national health insurance coverage in the pit and fissure sealants, expanding a support for low-income bracket, and differentiating the outpatient cost sharing according to socio-economic level.
