Objectives : The purpose of the study is to verify the correlation between teenagers' use of internet and temporomandibular joint disorders(TMJD) because TMJD patients gradually increase in high school students. Methods : Subjects were 221 male high school students attending liberal arts and commercial schools from 9 to 21 of April, 2012. Students completed self-reported questionnaire. Results : TMJD symptoms included crackling joint (32.1%), headache (18.6%), malocclusion (8.1%), and jaw fatigue and muscular aching (7.2%). Students having at least one symptom accounted for 49.8%. Students having at least one poor habit accounted for 83.7% and 34.0% of the students used internet for 3 hours.. Score of students experiencing shoulders and chest pain was $5.13{\pm}1.10$ (p<0.05). Score of TMD afflicting area revealed $4.67{\pm}2.73$ (p<0.05) in mastication pain ($4.13{\pm}2.73$ (p<0.05)) due to long hours of internet use. Score of jaw fatigue related to muscular pain was $4.31{\pm}1.96$ (p<0.01). Duration of computer use was related to perceived TMJD symptoms (r=.153). Long duration of computer use was related to poor oral cavity habits (r=.157). Conclusions : Male high school students can perceive slight TMD which needs self management and regular check-ups and try to prevent TMD by utilizing measurement tools on TMD. Also, this study helps to prevent from worsening TMD by shortening hours of computer utilization.

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.

Image distortions are typically characterized by degradations of structures. Dictionaries learned from natural images can capture the underlying structures in images, which are important for image quality assessment (IQA). This paper presents a general-purpose no-reference image quality metric using a GRadient-Induced Dictionary (GRID). A dictionary is first constructed based on gradients of natural images using K-means clustering. Then image features are extracted using the dictionary based on Euclidean-norm coding and max-pooling. A distortion classification model and several distortion-specific quality regression models are trained using the support vector machine (SVM) by combining image features with distortion types and subjective scores, respectively. To evaluate the quality of a test image, the distortion classification model is used to determine the probabilities that the image belongs to different kinds of distortions, while the regression models are used to predict the corresponding distortion-specific quality scores. Finally, an overall quality score is computed as the probability-weighted distortion-specific quality scores. The proposed metric can evaluate image quality accurately and efficiently using a small dictionary. The performance of the proposed method is verified on public image quality databases. Experimental results demonstrate that the proposed metric can generate quality scores highly consistent with human perception, and it outperforms the state-of-the-arts.
