Objectives: The purpose of this study was to obtain basal information to establish a proper birth-encouraging policy in the future through the survey of the attitude towards childbirth and its related factors among female students in junior, senior high school, and university. Methods: A survey was performed for 2 weeks in June, 2006, for a total of 688 female students which included 185 ones in a girls' junior high school and 242 ones in a girls' senior high school in Sacheon, and 261 ones in two universities in Jinju. The selfadministered questionnaires developed by the authors included the socio-demographic characteristics, the attitude towards childbirth, the preference of a son for their future child, the belief on relative importance of family or work after marriage, the seriousness perception of low birth rate in Korea, frequencies of education in school about low birth rate. The attitude was measured by an answer to the question of 'To what degree do you think you are going to have a child(or children)?' Results: The proportion of positive attitude towards their future childbirth was 76.2% in junior high school, 63.9% in high school, and 82.8% in university students (p<0.01). In the logistic regression analysis, the significant factors related with positive attitude towards future childbirth were school grade, preference of a son for their future children, and belief on relative importance of family or work after marriage. Conclusions: It suggests that the related factors with positive attitude towards future childbirth need to be considered to make a proper birth policy.

We presented a quad-rotor controlling algorithm design by using sensor fusion in this paper. The controller design technique was performed by a PD controller with a Kalman filter and compensation algorithm for increasing the stability and reliability of the quad-rotor attitude. In this paper, we propose an attitude estimation algorithm for quad-rotor based sensor fusion by using the Kalman filter. For this reason, firstly, we studied the platform configuration and principle of the quad-rotor. Secondly, the bias errors of a gyro sensor, acceleration and geomagnetic sensor are compensated. The measured values of each sensor are then fused via a Kalman filter. Finally, the performance of the proposed algorithm is evaluated through experimental data of attitude estimation. As a result, the proposed sensor fusion algorithm showed superior attitude estimation performance, and also proved that robust attitude estimation is possible even in disturbance.

This study was carried out to investigate fast food consumption patterns, nutrition knowledge, dietary attitude of middle and high school students in Busan. A questionnaire survey was conducted among 562 students from April 8 to April 22 in 2006. The results are summarized as follows. Convenience to eat is the best motive for visiting fast food restaurants. Nutrition knowledge scores of middle school male students were lower than those of the other groups. The more nutrition knowledge female students have, the lower fast food consumption became. There was no significant difference in nutrition knowledge and fast food consumption in male students. There was a significantly positive correlation between education levels of their parents and dietary attitude of the subjects(p<0.01). Pocket money showed a significantly negative correlation with dietary attitude and with fast food use frequency(p<0.05). There was a significantly positive correlation between nutrition knowledge and dietary attitude of the subjects. The use frequency of fast food showed a negative correlation with dietary attitude(p<0.01) and nutrition knowledge(p<0.05) of the subjects. Therefore, proper nutrition education is required to improve their nutritional status and dietary attitude.

The rigorous requirements of modern spacecraft missions necessitate a precise attitude determination strategy. This paper mainly researches that, based on three space-borne attitude sensors: 3-axis rate gyros, 3-antenna GPS receiver and star-sensor. To obtain global attitude estimation after an information fusion process, a feedback-involved Federated Kalman Filter (FKF), consisting of two subsystem Kalman filters (Gyros/GPS and Gyros/Star-sensor), is established. In these filters, the state equation is implemented according to the spacecraft's kinematic attitude model, while the residual error models of GPS and star-sensor observed attitude are utilized, to establish two observation equations, respectively. Taking the sensors' different update rates into account, these two subsystem filters are conducted under a variable step size state prediction method. To improve the fault tolerant capacity of the attitude determination system, this paper designs malfunction warning factors, based on the principle of ${\chi}^2$ residual verification. Mathematical simulation indicates that the information fusion strategy overwhelms the disadvantages of each sensor, acquiring global attitude estimation with precision at a 2-arcsecs level. Although a subsystem encounters malfunction, FKF still reaches precise and stable accuracy. In this process, malfunction warning factors advice malfunctions correctly and effectively.

Purpose: This study was to examine the changes in knowledge, attitudes, and preventive behaviors among elementary school students after providing them with tuberculosis prevention education. Methods: A total of 235 students from D elementary school in G city were selected. After completing tuberculosis prevention education, the subjects were surveyed five times for 16 weeks. 1,087 samples were included in the final analysis. One-way ANOVA, $Scheff{\acute{e}$'s test, Pearson's correlation, and multiple regression analysis were performed to examine the changes in tuberculosis-related knowledge, attitudes and preventive behaviors over time. Results: After 16 weeks from the education, the scores of preventive behaviors did not show any significant difference compared to the time right after the education. However, the scores of knowledge and attitudes tended to improve. In particular, 1st~2nd graders had high scores in both knowledge and attitude, and the scores of knowledge and attitude gradually increased over time. The correlation between knowledge, attitude, and preventive behavior regarding tuberculosis had a positive significance during the entire time of the survey. Conclusion: Positive associations between knowledge and attitude and between attitude and preventive behavior sustained for 16 weeks after tuberculosis education among elementary school students. This study suggests that tuberculosis prevention education conducted early on from lower grades can produce more educational effects and that it could be a foundation not only for developing knowledge of tuberculosis but also for cultivating adequate attitudes and forming active tuberculosis preventive behaviors.
