This study presents results of surveys conducted Incheon area using structured questionaire developed by researcher to determine the degree of knowledge, attitude and practice of breast feeding of mothers of infant. The suvjects were mothers of 84 Childs, 1-6 months of age. Results were as follows : 1. More than half of the subjects started breast feeding and breast-bottle feeding(61.9%) 2. Duration of breast feeding was under one month (9.6%), 1-2months(13.7%), 3-4months(5.5%), 5-6months(23.3%) and had continued breast feeding until they were questioned. 3. The 40.5% of mothers'never got information of breast feeding and 21.4% of mother got information of breart feeding through T. V. or radio. 4. Degree of mothers' knowledge of breast feeding was significantly correlated with mothers' attitude of breast feeding (r=.47, p<0.01) and degree of mothers' attitude of breast feeding was significantly correlated with mothers' practice of breast feeding(r=.34, p<0.01).

This paper describes a new approach that can extract the relative shift vectors between two aerial image sequences for implementing the visual navigation system. This method minimizes the noise included in the aircraft attitude information that represents the changes of the aircraft attitude using the statistical method and Kalman Filtering method. This result can be used to find the relative shift vectors which are independent of the attitude changes indicating the true trajectories of aircraft. We applied this method to the image about which we had already known the information of aircraft attitude, and that result showed that the errors were minimized successfully.

Passive attitude stabilization method has been widely used for attitude determination and control of cube satellite due to its advantage of system simplicity. In this paper, permanent magnet stabilization method for application of cube satellite attitude control has been introduced and its performance with and without hysteresis damper system has been investigated through a numerical simulation. The simulation results indicate that the permanent magnet stabilization combined with hysteresis damper shows much higher stabilization performance than the system without damper system.

Tourism marketing begins with understanding tourists' needs. However, understanding tourists' needs should be expressed by specific utility values rather than simple preference order for the purpose of developing tourism marketing strategies. This study aims at identifying tourist's stated preference of vacation destination attributes by using the conjoint analysis. In addition, this study is purposed to define relationship between attitude and preference, and to suggest implications to tourism marketing strategies. It was found that stated preference to such attributes as 'quality of accommondation', 'recreation activities' and 'accessibility' among the attitude segments was significantly different but stated preferences to diverse profiles made of these three attributes showed significant differences only in such attributes as 'quality of accommodation' and 'recreation activities'. This results make it possible to identify the function of preference to destination attributes in the vacation destination choice decision. It also embodies the relationship between tourist's attitude and vacation destination attributes.

Geomagnetic data from 3-axis magnetometer and the IGRF model (tilite - eccentric dipole model) were used to determine the attitude of a satellite. We compared the values of the geomagnetic model with the magnetometer data and two attitude angles, called $\alpha$ -angle and $\beta$-angle respectively, were calculated. From these angles we calculated simple bounds, $\gamma1$ and $\gamma2$, on the true attitude angle $\gamma$, which is used to detemine attitude, between the z-axis and the local vertical. And then we investigated conditions of attitudes of UoSAT-11, 14, 22.

Attitude command response type required for enhanced handling qualities of helicopter can be implemented by mechanical automatic flight control system with SAS actuators which have limited authorities. However, the early saturation of SAS actuator hinders the helicopter from following the attitude command for large stick command. Auto-trim controller can delay SAS actuator's saturation by utilizing trim actuators and allows the attitude command response type for larger stick command. This paper describes the control law for limited authority system of helicopter with auto-trim. Limited authority system is applied to BO-105 linear dynamic model and simulation is performed along with handling quality analysis.

This study investigates how anticipated value(attainment value, intrinsic value, utility value, and reward value) and self-efficacy in providing information have an influence on continuance intention to provide information in the context of online community or social media. We propose a conceptual model for examining the framework for the effect of anticipated value on attitude toward providing information, and the effect of attitude toward providing information and self-efficacy in providing information on continuance intention to provide information. Proposed research model is empirically assessed using the survey data obtained from 221 respondents in Korea. Results show that attainment value and intrinsic value have a significant impact on attitude toward providing information, whereas utility value and reward value are found to be insignificant. In addition, attitude toward providing information and self-efficacy in providing information are positively and significantly related to continuance intention to provide information.

The purpose of this study was to investigate the relational between elderly women＇s sex-role attitude and their marital satisfaction. For this purpose, a questionnaire was surveyed 186 elderly women living in Kwangiu and Chonnam. The collected data were analyzed by using frequency, percentage, mean, standard deviation, ANOVA and stepwise regression analysis. The results of this research were as follows ; First The total points of the elderly women＇s sex-role attitude score was 16.4, which was represented mixed trends of traditional and modem. And the total points of the elderly women＇s marital satisfaction score was 31.6, which was higher than the median 30. Second, Elderly women＇s sex-role attitude score was meaningfully different according to education level, health state, economic state. And elderly women＇s marital satisfaction score was meaningfully different according to social activity, economic state, health state, education level, age. Third, As the results of regression analysis, it was shown that the highest influencing variable on their marital satisfaction was the social activity, economic state, education level. All of them explained 19% of their marital satisfaction. (Korean J Human Ecology 1(2):48-60, 1998)

The purpose of this study is to examine the realities of knowledge and attitude about smoking among high school students, to analyze the relation among knowledge of smoking attitude about smoking, and smoking behavior. For the data, 1,522 boys' high school students living in Pusan were selected. The data were analyzed with the SPSS PC+ statistical package using t-test, multiple regression and path analysis. The main results are as follows; First, smoking group has lower knowledge of smoking than non-smoking group. Second, smoking group has more positive attitude about smoking than non-smoking group. Third among the demographic variables pecket money, scholastic attainments, grade, SES, and religion influence on smoking behavior directly and indirectly. Fourth, among the smoking environmental variables parents' smoking, sibling's smoking. the number of smoking family. close friends' smoking, the number of smoking friends, family's thought about smoking, knowledge of smoking attitude about smoking influence on smoking behavior directly and indirectly.

Purpose: The aim of the study was to identify factors influencing confidence in performing cardiopulmonary resuscitation (CPR) of university students. Methods: Data were collected from 261 students recruited from 2 cities using a questionnaire covering confidence, knowledge and attitude in regard to CPR. Results: There was a significant positive correlation between confidence and knowledge (r=.37, p<.001), between attitude and confidence (r=.61, p<.001), and between knowledge and attitude (r=.61, p<.001). Confidence in performance increased as knowledge, attitude, grade, CPR training frequency and educational satisfaction increased. Conclusion: There is a need for CPR training programs that can improve practical training and educational satisfaction of university students.
