This study was conducted to suggest a necessity in student health promotion device by comparing the health status and identifying the environmental health influence of the elementary students in Busan. Five schools were selected as sample group based on the number of air pollutant emitting facilities and whole 6th grade 825 students(391 from industrial area and 434 from residential area) were selected from these elementary school. The data were collected from convenient sample based on written questionnaires from 1st to 30th, Nov, 2001. The student group who lives in an industrial area experiences more the symptoms of the eyes(p=.033) and a cold(p=.000)(p=.015), more frequent indirect smoking condition(p=.023, p=.001), and think ill of the relation about air pollution and health(p=.002), cognition of the surroundings(p=.000), and perception of subjective health status(p=.000). There were not significant differences in the number of student in asthma score by their residents, but there were significant differences at the dwelling term of the students in asthma score(P=.002). According to the above results, there must be a device of preventive treatment and early diagnosis of disease needed for the student in industrial areas because they are in relatively poor health and social economic status than residential areas.

Planetary global localization is necessary for long-range rover missions in which communication with command center operator is throttled due to the long distance. There has been number of researches that address this problem by exploiting and matching rover surroundings with global digital elevation maps (DEM). Using conventional methods for matching, however, is challenging due to artifacts in both DEM rendered images, and/or rover 2D images caused by DEM low resolution, rover image illumination variations and small terrain features. In this work, we use train CNN discriminator to match rover 2D image with DEM rendered images using conditional Generative Adversarial Network architecture (cGAN). We then use this discriminator to search an uncertainty bound given by visual odometry (VO) error bound to estimate rover optimal location and orientation. We demonstrate our network capability to learn to translate rover image into DEM simulated image and match them using Devon Island dataset. The experimental results show that our proposed approach achieves ~74% mean average precision.

The purpose of this study was to identify factors that influenced elementary school teachers in choosing websites that support science teaching and learning. The participants of this study were four elementary school teachers. The data was collected through semi-constructed and in-depth interview. The results of the research are as follows: First, the individual factors that influenced participants to choose a website were teacher's thinking about appropriate science teaching and learning methods and teacher's lack of ability to prepare science lessons. Second, the surroundings factors were the image of the teachers using the website, the formation of consensus, belonging to the peer teachers, and students' preferences and interests. Third, participants chose a website where they could provide ideas for science lessons that are not available in textbooks and instructional materials for all subjects, and see stories and tips related to teaching career. In addition, the website was selected according to whether the developer of science instructional materials was a teacher, whether the materials uploaded on the website were up-to-date, and whether the teachers can learn by themselves to prepare for the science class. Fourth, participants considered the design and interactivity of the website and chose a website that is easy to search for information. Finally, we suggested the implications for building the websites that support science teaching and learning.

Objectives: This study assessed the influences of various factors that are related to youth smoking such as gender, age and type of school, and we wanted to provide supporting data for tailored and effective policy initiatives to reduce adolescent smoking. Methods: A self-report survey was conducted on 14,910 teen-age students who were selected based on the nationwide distribution of students in large and small cities and counties, the gender ratio of the students and the ratio of students attending various type of school at 38 middle and high schools in six representative areas of each province. The survey was handled and managed by a health education teacher at each school. Binary and multinomial logistic regression was used in the analyses. Results: Smoking by adolescents was associated with gender, age and even height. Male high school students tended to smoke more than female high school students, but this differences was not significant for middle school students. The older the adolescents were, the more likely that they smoked, except for the female high school students. Height was meaningful for all adolescents, except for the boys at the vocational high schools. Monthly allowance was significant for all adolescents. School factors such as type of school and the students' school performance were also crucial factors. Attending a vocational high school was strongly related to smoking, especially for girls. Students' school performance and the perceived level of stress were strongly associated with smoking, especially for boys. Home factors such as the relationship with parents and conversation time with family members were closely related to smoking behavior. Knowledge about the health hazard of smoking was also found to be strongly related to adolescent smoking. Conclusions: In conclusion, demographic factors, school factors, home surroundings and the perception on the harmfulness of smoking are strongly related to adolescent smoking behavior, but these differ from gender and type of school.

Recently, many implantable medical devices have been developed and manufactured in many countries. In these devices, generally, energy is supplied by a transcutaneous method to avoid the skin penetration due to the power wires. As the most transcutaneous power transmission methods, the electromagnetic coupling between two coils and resonance at a specific frequency has been used widely. However, in case of a transcutaneous power transmitter with a fixed switching frequency to drive an electromagnetic coil, inefficient power transmission and thermal damage by the undesirable current variation may occur, because the electromagnetic coupling state between a primary coil and a secondary coil is very sensitive to skin thickness of each applied position and by person. In order to overcome these defects, a transcutaneous power transmitter of which operating frequency can be automatically tracked into the resonance frequency at each environment has been designed and implemented. Through the results of experiments for different coil surroundings, we have been demonstrated that the implemented transcutaneous power transmitter can track automatically into a varied resonance frequency according to arbitrary skin thickness change.
