The purpose of this study was to identify the concepts of body image, weight control and food behavior in 520 Korean high school seniors from Seoul and Gyeonggi Province. A questionnaire survey was conducted to investigate body image, concern of weight control, experience of weight control, the first time to try weight control, plan for weight control, reasons of weight control and food behaviors related with weight control. Anthropometric parameters such as weight and height were measured. Finally, data from 497 high school seniors were used for statistical analysis. The results were as follows. Many subjects had misperceptions. Among the subjects who perceived themselves as 'fat', 57.8% were normal weight and 0.5% underweight. Among the subjects who perceived themselves as 'thin', 59.5% were normal weight, 0.9% overweight and 0.9% obese. Girls were more concerned about weight control than boys (4.20 vs. 3.66). Weight loss had been experienced by 61.5% of the subjects and weight gain by 12.8%. First weight control was attempted by 71.3% of the subject at high school and by 28.7% at middle school. The majority of subjects planned for weight control before their freshman year. The boys choose 'health' as the primary reason for weight control, whereas the girls chose 'good appearance'. The total score of food behaviors varied significantly according to BMI. Overweight and obese subjects had more desirable food behaviors than normal weight and underweight subjects (24.00, 24.06 vs. 21.92, 21.52). However, total scores of food behaviors showed no variation according to sex, weight control attempt and body image. In conclusion, the high school seniors had misconceptions about body image and weight control. They were exposed to a high risk of inappropriate weight control and food behaviors. Therefore, proper nutritional education programs need to be developed for high school seniors to prevent nutrition problems related to weight control and to maintain desirable food behaviors.

The aim of this study was to analyze the factors related to whole saliva flow and the xerostomia for the ground use of the materials in developing oral health improvement program and life quality improvement program. So, this study performed a questionnaire survey, targeting at 160 adults, older than 40 years, living in Gyeonggi and Incheon provinces from January to February 2011 and measured unstimulated salivary flow rate and stimulated salivary flow rate. The results are as followings. The group of participants who took gums and candies to relieve oral dryness had low stimulated whole saliva flow. The group of participants who graduated from middle schools, who separated by death, who were not healthy with menopause, and who recognized periodontal disease symptoms and tongue burning sensation recognized more symptoms of dry mouth than others. In addition, the group of participants who were not satisfied with life so much, who couldn't feel the meaning of life, and who recognized negative feelings frequently recognized symptoms of dry mouth more. Women, the group of participants who graduated from middle schools, who suffered from depressive symptoms, and who recognized halitosis had low unstimulated whole saliva flow. The group of participants who graduated from middle schools, who were not satisfied with life so much, who couldn't feel the meaning of life, and who were not satisfied with themselves had low stimulated saliva flow.

In this paper, a new security algorithm to recognize the type of the vehicle with the vehicle image as a input image is suggested. The vehicle recognition security algorithm is composed of five core parts, such as the input image, background removal, edge areas extraction, pre-processing(binarization), and the vehicle recognition. Therefore, the final recognition rate of the security algorithm for vehicle type recognition can be affected by the function and efficiency of each step. After inputting image into a gray scale image and removing backgrounds, the binarization is performed by extracting only the edge region. After the pre-treatment process for making outlines clear, the type of vehicles is categorized into large vehicles, passenger cars and motorcycles through the ratio of height and width of the vehicle.

This research investigated differences of perception ratio and processes of memory reconstruction. To examine the differences in perception for positive or negative events related to individual subjective well-level, 199 participants were asked to report the perceived ratio of positive versus negative events for the provided event list. Also, recall differences of positive versus negative events were examined in relation to individual differences in happiness. Results partially supported the hypothesis that happy people perceive more positive stimulus in a given situation than less happy people. Happy people also showed more positive percentage in recalled events than actual ratio while unhappy people reported less positive recall percentage than actual ratio. These findings indicate existence of cognitive process that enhances positive or negative memory related to subjective well-being. Significant correlation between perceived ratio and recalled ratio further supports this proposition. Finally, theoretical implications of the present research and suggestions for future research were discussed.

Purpose: The objective of this study was to examine the effect of the body shape discordance, the difference between true body type based on body mass index (BMI) and self-recognized body image, on nutrient intake, weight control attempt, and mental health in Korean adults. Methods: Subjects were persons aged 19~64 years (4,382 men and 6,226 women) who participated in the 2010~2012 Korea National Health and Nutrition Examination Survey. Subjects were categorized as RL (Group recognized as lighter than BMI criteria), RA (Group with agreement between BMI criteria and self-recognized body image), and RH (Group recognized as heavier than BMI criteria) according to the difference between actual body type based on BMI and self-recognized body image. Results: Means of BMI in RH groups were lower than or equal to that of RA groups in all groups. No significant differences in total energy intake were observed among the three groups in men, but total energy intake was higher in the RL group than in the RH group in 30~49 year old women. Proportion of carbohydrate was the highest in the RL group among 30~49 year old women. RH groups paid more attention to weight control and had less weight gain than other groups. Higher proportions of depressive symptoms were reported in the RH group in 19~29 year old men, while a higher proportion of depressive symptoms were reported in the RL group in 50~64 year old men. Conclusion: The current findings suggest an association of perceiving body shape with energy intake, weight control attempt, or depressed mood in some age groups. Body image perception can influence eating, weight control attempt, and depressed mood, therefore proper body image perception should be established in Korean adults.

In this study, the effects of driver's neuroticism on situation awareness(SA), eye movement(EM), and driving performance were examined. In Experiment 1, in which static driving scenes were presented, it was found that the drivers of higher neuroticism showed shorter percentage of dwell time and less percentage of fixation counts for the peripheral area than those of lower neuroticism, although SA scores yielded no difference between the two neuroticism groups. In Experiment 2, differences in the drivers' driving performances as well as SA and EM as a function of neuroticism were compared using driving simulation. The results of Experiment 2 showed the followings. First, contrasting to Experiment 1, the high neuroticism group showed lower SA score than low neuroticism group. Second, the pattern of EM was similar to those of Experiment 1. Third, high neuroticism group deviated more from center of road, and drove slower than low neuroticism group.

The aim of the present study is twofold. One is to confirm a hypothesis that a student's rate concept influences her conceiving change of a function in the view of rate of change and the other is to build up foundations for understanding the transition process from her rate concept to the concept of rate of change when she investigates the change of concentration as an intensive quantity. We explored how three participating high school students recognized and expressed change of given functions by using their rate concept as a conceptual tool. The result indicates that a change in students' rate concept might have an effect on understanding how function values change in term of rate of change. We also expect that it could be a catalyst for further research for clarifying the relationship between students' rate concept and their development of a concept of rate of change as a foundation for learning calculus.
