The purpose of this study was to examine the effects of self-esteem and the body cathexis on consumers' attitude in acceptance of fashion trends. The subjects were 460 women from in their 20's to 60's living in Daegu area. The scale for self-esteem and the body cathexis were used and self-report questionnaires were applied to measure the acceptance of fashion trends. The data were analysed by frequency, mean, factor analysis, ANOVA and Duncan-test using SPSS-package. The results were as follows. First, the results of analysing the factor of the response of acceptance of fashion trends identified three attitudes; 'active to fashion trends', 'passive to fashion trends' and 'unconcern to fashion trends'. Secondly, there were significant differences in the acceptance of fashion trends in accordance with an age. Thirdly, there were significant differences in the acceptance of fashion trends and clothing shopping orientation according to one's self-esteem and the body cathexis. It appeared that higher the level of self-esteem and the body cathexis predicts an 'active to fashion trend' attitude in acceptance of fashion trends.

This study was intended to collect the baseline information on dietary behavior of adults to develop nutrition education program in the context of health promotion at community level. Nutrients intake of 135 housewives were assessed by 24 hour recall methods. Also food habits, nutrition knowledge and attitude were investigated by self-administered questionnaires. Our results indicated dietary intake of calcium and vitamin $B_2$ were insufficient when they were compared to Korean recommended dietary allowances(RDA). Among five food groups, intakes of milk and dairy product was inadequate as compared to the recommended amount. When we compared the fatness indices to self-evaluated meal problems, overeating and speedy eating were significantly related to fatness indices. Fatness indices such as relative body weight(RBW) and body mass index(BMI) were significantly higher in the subjects who self-evaluated their unsound food behavior as overeating. However, there were no significant differences of food habit score and nutrition knowledge among groups classified by fatness or meal problem. Body fat ratio, frequencies of night snack and skipping meal significantly increased with age. Food habit score was positively related to health-concerned attitude and active attitude toward change. We concluded that nutrition education program for housewives should include detailed strategies to modify unsound food behaviors for healthy weight.

The women selected by random sampling were classified into four groups by their body cathexis and Make-up attitude in order to investigate differences in Maslow Need and Make-up behavior. Cluster was classified into four groups: positive congruity(G1), positive incongruity(G2), negative congruity(G3), negative incongruity(G4). The result are as follows: Four groups showed meaningful difference each other between the peculiarity of need. That is, this thesis examined the strength of seven needs and found out that G1 group had the strongest needs in seven ones, comparing with four groups. Next, this thesis found out that G2 had the strongest ones in belonging need, self-respect need, and aesthetic need, and that G4 had the strongest ones in physiology need, self-realization need, and recognition need. So it showed somewhat a little difference among groups. G1>G2>G3>G4, in order, emphasized fashion, alignment, ostentation, and tool in Make-up behaviors, and customs, and G1>G2>G4>G3, in order, emphasized respective peculiarity.

In the three axis control of Low Earth Orbit (LEO) satellite by using reaction wheel and gyro, a reaction wheel produces the control torque by the wheel speed or momentum, and a gyro carries out measuring of the attitude angle and the attitude angular velocity. In this paper, the dynamic modelling of LEO is consisted of the one from the rotational motion of the satellite with basic rigid body model and a flexible model, in addition to the reaction wheel model. A robust controller $(H_\infty)$ is designed to stabilize the rigid body and the flexible body of satellite, which can be perturbed due to disturbance, etc. The result obtained by $H_\infty$ controller is compared with that of the PI (Proportional and Integration) controller, which has been traditionally using for the stabilizing LEO satellite.

This paper describes differences of performance when the orbit attitude model is applied to the respective images obtained from two different types of satellite. The one is Spot that rotates its pointing mirror and the other is Kompsat-2 that rotates its whole body when they obtain imagery for target. Our research scope is limited to the orbit-attitude model only as its good performance was proved in prior investigation. Model performances between two images were compared with sensor model accuracy and 3D coordinates calculation. The results show performances of the orbit-attitude model for each image type were different. For Spot imagery, the model required attitude angle to be included as adjustment parameters. For Kompsat-2 imagery, the model required high-order parameter for adjustment. This implies that satellite sensor model may be applied differently in accordance with platform's attitude control scheme and accuracy. Understanding of this information can be a base for improvement and development of model and application for new satellite images.

Magnetic actuation utilizes the mechanic torque that is the result of interaction of the current in a coil with an external magnetic field. A main obstacle is, however, that torques can only be produced perpendicular to the magnetic field. In addition, there is uncertainty in the Earth magnetic field models due to the complicated dynamic nature of the field. Also, the magnetic hardware and the spacecraft can interact, causing both to behave in undesirable ways. This actuation principle has been a topic of research since earliest satellites were launched. Earlier magnetic control has been applied for nutation damping for gravity gradient stabilized satellites, and for velocity decrease for satellites without appendages. The three axes of a micro-satellite can be stabilized by using an electromagnetic actuator which is rigidly mounted on the structure of the satellite. The actuator consists of three mutually-orthogonal air-cored coils on the skin of the satellite. The coils are excited so that the orbital frame magnetic field and body frame magnetic field coincides i.e. to make the Euler angles to zero. This can be done using a Neural Network controller trained by PD controller data and driven by the difference between the orbital and body frame magnetic fields.

Purpose: The purpose of this study was to examine factors related to attitudes to menstruation in elementary school girls according to menarche experience. Methods: Data were collected using a structured questionnaire from 208 girls in 5th or 6th grade (90 who were menarche and 118 who were not). The study was a cross-sectional study. Data were analyzed using SPSS/WIN 18.0 program for descriptive statistics, t-test, ANOVA, Pearson correlation, and multiple regression. Results: There were significant differences in body image, menstrual knowledge and attitude between the two groups of students. Results from the multiple regression analysis revealed difference in related factors and in the magnitude of the relationship evaluated by standardized beta coefficients. Significant factors, listed by the magnitude of beta coefficients, among students in menarche were positive affect of menarche, self-oriented perfectionism-critical, negative affect of menarche. Significant factors among non-menarche students were menstrual knowledge and self-oriented perfectionism-critical. Conclusion: There are differences between menarche and non-menarche girls in attitude to menstruation and related factors. Based on the results of the present study, systemic health education according to differences between the two groups should be developed to foster positive attitudes to menstruation.

The controller of a model reference adaptive control monitors the plant's inputs and outputs to acknowledge its characteristics. It then adapts itself to the characteristics it encounters instead of behaving in a fixed manner. An important part of every adaptive scheme is the adaptive law for estimating the unknown parameters on line. A more precise model is required to improve performance and to stabilize a given dynamic system, such as a satellite in which performance varies over time and the coefficients change due to disturbances, etc. After model identification, the robust controller ($H{\infty}$) is designed to stabilize the rigid body and flexible body of a satellite, which can be perturbed due to disturbance. The result obtained by the $H{\infty}$ controller is compared with that of the proportional and integration controller which is commonly used for stabilizing a satellite.
