Purpose: The purpose of this study was to compare Preventive Health Behaviors (PHBs) in adults in Korea and the United States and identify factors influencing PHBs. Methods: This was a secondary data analysis study using data from the 2008 Korean National Health and Nutrition Examination Survey and the 2008 USA Behavioral Risk Factor Surveillance System. The PHBs were predicted using multiple linear regression analysis. Results: 1) The total score of PHBs was significantly higher in American males (5.11) than in Korean males (4.78). There was also a significant difference between Korean females' total score (6.57) and American females'(6.75). 2) Age, marriage, monthly income, subjective health status, and cardiovascular disease were significant factors of PHBs in Korean males (p<.001). However, age, marriage, education, monthly income, health insurance, subjective health status, and cardiovascular disease were significant factors in American males (p<.001). In Korean females, only age and education were significant predictors (p<.001). However, six variables(age, marriage, education, monthly income, health insurance, and subjective health status) were significant predictors in American females (p<.001). Conclusion: There were different variables in predicting PHBs between Koreans and Americans. Each country should focus on those significant predictors to promote the PHBs for adults.

The rapid growth of smartphone-to-Internet of Things (IoT) connections and the explosive demand for data usage centered on mobile video are increasing day by day, and this increase in data usage creates many problems in the IP system. In a full-based environment, in which information requesters focus on information providers to receive information from specific servers, problems arise with bottlenecks and large data processing. To address this problem, CCN networking technology, a future network technology, has emerged as an alternative to CCN networking technology, which reduces bottlenecks that occur when requesting popular content through caching of intermediate nodes and increases network efficiency, and can be applied to military information and communication networks to address the problem of traffic concentration and the use of various surveillance equipment in full-based networks, such as scientific monitoring systems, and to provide more efficient content.

The rapid rise in the incidence of obesity has emerged as one of the most pressing global public health issues in recent years. The underlying etiological causes of obesity, whether behavioral, environmental, genetic, or a combination of several of them, have not been completely elucidated. The obesity epidemic has been attributed to the ready availability, abundance, and overconsumption of high-energy content food. We determined here by Pearson's correlation the relationship between food type consumption and rising obesity using the loss-adjusted food availability data from the United States Department of Agriculture (USDA) Economic Research Services (ERS) as well as the obesity prevalence data from the Behavioral Risk Factor Surveillance System (BRFSS) and the National Health and Nutrition Examination Survey (NHANES) at the Centers for Disease Control and Prevention (CDC). Our analysis showed that total calorie intake and consumption of high fructose com syrup (HFCS) did not correlate with rising obesity trends. Intake of other major food types, including chicken, dairy fats, salad and cooking oils, and cheese also did not correlate with obesity trends. However, our results surprisingly revealed that consumption of com products correlated with rising obesity and was independent of gender and race/ethnicity among population dynamics in the U.S. Therefore, we were able to demonstrate a novel link between the consumption of com products and rising obesity trends that has not been previously attributed to the obesity epidemic. This correlation coincides with the introduction of bioengineered corns into the human food chain, thus raising a new hypothesis that should be tested in molecular and animal models of obesity.

This study suggests a method of detecting the still object, which becomes a cause of danger within the crossroad. The Inverse Perspective Transform was performed in order to make the object size consistent by being inputted the real-time image from CCTV that is installed within the crossroad. It established the detection area in the image with the perspective transform and generated the adaptative background image with the use of the moving information on object. The detection of the stop object was detected the candidate region of the stop object by using the background-image differential method. To grasp the appearance of truth on the detected candidate region, a method is proposed that uses the gradient information on image and EHD(Edge Histogram Descriptor). To examine performance of the suggested algorithm, it experimented by storing the images in the commuting time and the daytime through DVR, which is installed on the cross street. As a result of experiment, it could efficiently detect the stop vehicle within the detection region inside the crossroad. The processing speed is shown in 13~18 frame per second according to the area of the detection region, thereby being judged to likely have no problem about the real-time processing.

Background: Colorectal cancer is a main leading cause of cancer death in western countries. Although many studies have been conducted on incidence trends all over the world in recent years, information regarding changes in incidence of colorectal cancer in Iran is insufficient. The present study of colorectal cancer in the west of Iran during recent years was therefore performed. Materials and Methods: The registered data for colorectal cancer cases in National Cancer Registry System were extracted from the Ministry of Health and Medical Education, Center for Disease Control and Management. The codes from 18-21 among cancers were selected for colon and rectum cancers. Incidence rates were standardized directly using WHO population. The significance of incidence rate trends during 2000-2005 was tested through Poisson regression. Results: 762 cases of colorectal cancer were observed during 6 years in this region, with a gender ratio of men to women of 1.2. It increased from 65 cases in 2000 to 213 cases in 2005 or from 1.5 per100,000 per persons per year to 4.8. Significant increasing trends were evident in Kermanshah and Hamadan provinces; however, change did not reach significance in Ilam and Kurdistan provinces. Conclusions: Colorectal cancer has an increasing trend in the west of Iran. Although it seems that the increasing rate of colorectal cancer is due to increasing of cancer risk factors, some proportion may be related to the improvement of surveillance systems in Iran.

Foodborne diseases (FBD) pose significant public health problems and economic losses worldwide. In recent years, emerging foodborne diseases have resulted mainly from novel bacteria, viruses, protozoa, mycotoxins, prions in animal and plant sources. The consumption of unsafe food contaminated with harmful bacteria, viruses, parasites or chemical agents or naturally occurring toxins results in high morbidity and mortality. However, estimating the incidence and burden of FBD is a huge global challenge due to the difficulty in food source attribution to specific pathogenic or chemical hazards, underreported cases, diagnosing how infections are transmitted or when a person is infected are not well understood and thus makes the control of FBD very challenging. Therefore, implementing comprehensive food safety strategies and policies, enhancing surveillance, ensuring resilient health system, and intensifying education and training to ensure safe food and prevent foodborne diseases is everybody's responsibility.

This paper describes new moving target detection technique combining two algorithms to detect targets and reject clutters in video frame images for surveillance system: One obtains the region of moving target using phase correlation method using $N{\times}M$ sub-block images in frequency domain. The other uses adaptive threshold using learning weight for extracting target candidates in subtracted image. The block region with moving target can be obtained using the characteristics that the highest value of phase correlation depends on the movement of largest image in block. This technique can be used in camera motion environment calculating and compensating camera movement using FFT phase correlation between input video frame images. The experimental results show that the proposed algorithm accurately detects target(s) with a low false alarm rate in variety environment using the receiver operating characteristics (ROC) curve.

Purpose: The social environment of easy access to medicines and arbitrary personal decisions leading to overdose aggravate unintentional medicine poisoning. This study aimed to investigate the characteristics of patients who visited emergency departments with unintentional medicine poisoning and reasons for poisoning based on age group. Methods: We retrospectively collected patients who experienced unintentional medicine poisoning based on data from the national injury surveillance system between 2013 and 2016. Subjects were classified into three groups based on age (0-14 years, 15-64 years, and ${\geq}65\;years$). We identified sex, insurance, time of poisoning, place, alcohol co-ingestion, hospitalization, death, and reason for poisoning in each age group. Results: A total of 27,472 patients visited an emergency department with poisoning during the study period; 1,958 patients who experienced unintentional poisoning were enrolled in this study. Respiratory medicine was the most frequent medicine in those younger than 15 years of age, and sedatives and antipsychotic drugs were the most common in patients older than 15 years of age. In total, 35.1% of patients older than 65 years were hospitalized. The most common reasons for poisoning were careless storage of medicine in those younger than 15 years of age and overdose due to arbitrary decisions in those older than 15 years of age. Conclusion: Unintentional medicine poisoning has distinct characteristics based on age group, and strategies to prevent poisoning should be approached differently based on age.

Background: Food consumption is one of the most important routes for radionuclide intake for the public; therefore, there is the need to have a comprehensive understanding of the amount of radioactivity in food products. Consumption of radionuclide-contaminated food could increase potential health risks associated with exposure to radiation such as cancers. The present study aims to determine radioactivity levels in some food products (milk, rice, sugar, and wheat flour) consumed in Mali and to evaluate the radiological effect on the public health from these radionuclides. Materials and Methods: The health impact due to ingestion of radionuclides from these foods was evaluated by the determination of activity concentration of radionuclides ²³⁸U, ²³²Th, ⁴⁰K, and ¹³⁷Cs using gamma spectrometry system with high-purity germanium detector and radiological hazards index in 16 samples collected in some markets, mall, and shops of Bamako-Mali. Results and Discussion: The average activity concentrations were 9.8±0.6 Bq/kg for ²³⁸U, 8.7±0.5 Bq/kg for ²³²Th, 162.9±7.9 Bq/kg for ⁴⁰K, and 0.0035±0.0005 Bq/kg for ¹³⁷Cs. The mean values of radiological hazard parameters such as annual committed effective dose, internal hazard index, and risk assessment from this work were within the dose criteria limits given by international organizations (International Commission on Radiological Protection and United Nations Scientific Committee on the Effects of Atomic Radiation) and national standards. Conclusion: The results show low public exposure to radioactivity and associated radiological impact on public health. Nevertheless, this study stipulates vital data for future research and regulatory authorities in Mali.
