This study was conducted to provide information about the behavioral intentions to diet in adolescent females. To explain the behavior intention to diet, a conceptual framework based on the ' Social Support, Control and the Stress Process Model ' and the ' Theory of Reasoned Actio ' was used. The survey was carried out by self-questionnaires with 463 female high school and college students in Daegu. Analysis of data was done by using mean, correlation and multiple regression analysis with the SAS computer program. Subjects were divided into 3 groups-underweight, normal weight, and overweight-according to their current body size. The most powerful influencing factor related to perceived stress -that is dissatisfaction with body image- was the current figure, regardless of current body size. The fatter the current body size, the higher the score for the behavioral intention to diet. In attitude toward the behavior of dieting, the fatter the current figure, the higher the attitude score, and the belief of behavioral outcome was the main decision variable. For the score of the subjective norm, the overweight group was significantly higher than other groups. The influencing factors for the behavioral intention to diet were perceived stress and attitude toward dieting behavior, especially beliefs of behavioral outcome.

Rapid urbanization causes a variety of transportation problems, including traffic delay. Then transportation engineers would get involved in trying to solve traffic delay through road constructed and uncongested policy. But lately, traffic policy changed from vehicle-dominated to humandominated and green transportation. Road diet is one of green transportation. Road diets reduce the number of lanes, lane width because supplement space for green transportation including a bicycle road, side-walk, etc. A study on road diets not enough then this study performed a basic study for road diets. This study on lane width reduce for road diets through analyzes sway of moving vehicle. This study results shows lane width of a compacts-size car needs 2.34~2.70m and lane width of a full-size car needs 2.62~2.89m. According to this study lane width can reduce therefore lane width design criterion have to be relieved. This study will be used in a road width reduce including a road diets, road in process of construction and so on.

Second, the correlation of body size perception factor and appearance management behavior was Middle school boys and girls tended to manage their appearance using a diet rather than doing exercise in obesity distortion perception group(the group perceive obeser than real body size). It needs to be properly guided. Third, the appearance management behavior of slimness distortion perception group(the group perceive slimmer than real body size) and normal group was examined. While middle school boys did only exercise management, middle school girls did all but exercise management. Their education should be distinguished. Finally, while slimness distortion perception group did diet management in both middle school boys and girls, they tended not to manage body correction or exercise. A tendency to depend only on a diet in the group who should perceive their need of exercise should be corrected. In order to correct the distorted body perception and appearance management behavior of middle school boys and girls, it is recommended to educate a standard body size through home management education which is a regular curriculum, and at the same time to guide them to perceive their actual body size correct.

The purpose of this study was to investigate the general characteristics, body shape, and perceptions of weight control in individuals consuming functional health foods and weight-control foods. The survey was conducted between April 15 and June 17, 2010 among 199 (57 males and 142 females; age range, 25-45 years) in Seoul and Gyeonggi-do, who experienced eating functional health foods or weight control foods during the past year (June 2009 to June 2010). The subjects were divided into a weight-control food group (89 adults) and a functional health food group (110 adults). The subjects were comprised of a high proportion of aged (average age, $34.2{\pm}5.9$ years), graduates (71.9%), and married (65.8%) individuals. In the weight control food group, gender, age, and educational background were similar and the ratios of service/technical employees, college students, and normal-weight individuals [body mass index (BMI), < 23] were high. BMI was significantly different by gender (p < 0.001), age (p < 0.01), marital status (p < 0.001), and job type (p < 0.001). Self-perceived health status showed a higher response for "in good health" in the 35-44 year old group than that in the 25-34 year old group (p < 0.05). Male group satisfaction for body shape was significantly higher than that in the female group. The main reason for going on a diet was significantly different by gender (p < 0.05) and BMI (p < 0.01). The main motives for dieting were "because I am not at an ideal weight" and "because of the social atmosphere and the attention of others " in men, but "can't wear the clothes I want" in women (p < 0.01). The most preferable product type related to the two groups was significantly different by job (p < 0.001) and BMI (p < 0.05). However, no significant differences were observed for questions about body shape perception and weight control. Consumers who had different general characteristics and used diet products perceived body shape and weight control differently. Additionally, no meaningful differences were observed when the results were categorized by product type, except job and BMI, but the distribution of consumer characteristics showed different tendencies. These results can be utilized as basic data for developing new diet products to help people control their weight more scientifically and appropriately in the future.
