Accurate mathematical models of spacecraft components are an essential of spacecraft attitude control system design, analysis and simulation. Gyro is one of the most important spacecraft components used for attitude propagation and control. Gyro errors may seriously degrade the accuracy of the calculated spacecraft angular rate and of attitude estimates due to inherent drift and bias errors. In order to validate this model, nominal case simulation has been performed and compared for the low range mode and high range mode, respectively. In this paper, a mathematical model of gyro containing the relationships for predicting spacecraft angular rate and disturbances is proposed.

Purpose: This study was conducted to identify the factors affecting the attitudes toward brain death organ donation among nurses and doctors in an operating room. Methods: A descriptive research was used. The participants included 90 nurses and 30 doctors who had experience of operating organ transplantation for brain death organ donation. Data were collected from March 12 to May 23, 2020 in the one tertiary general hospital. The outcome measures were perception and attitude of death and attitude towards brain death organ donation. Results: Attitudes toward brain death organ donation was influenced by type of occupation, intention of organ donation and attitude toward death. In addition, the explanatory power of the total variance was 52.1%. Conclusions: Based on the results, it is necessary to prepare an intervention to improve awareness of the brain death and the brain death organ donation.

본 연구는 어린이가 일상에서 노인과의 접촉을 통해 노인에 대한 차별적 태도(Ageist attitude)를 완화할 수 있는지, 해당 태도의 개선방안을 탐색하였다. 명시적 태도(Explicit attitude)의 측정에 사용되는 자기보고식(Self-reported) 척도가 의식에서 여과된 수준의 편견만 반영하는 한계를 고려해, 내면의 차별적 인식을 나타내는 '암묵적 태도(Implicit attitude)'를 측정하였다. 명시적 태도 측정에는 웃는 얼굴 5점 척도를, 암묵적 태도 측정에는 어린이용 암묵적 연령 연합검사(Children Implicit Age-association Test)를 사용하였다. 서울 및 수도권 초등학교 4~6학년 초등학생 503명의 자료를 수집했으며 기술통계, 다항 및 서열 로지스틱 회귀분석 방법으로 분석하였다. 분석결과는 크게 세 가지로 요약된다. 첫째, 노인에 대한 어린이의 명시적 태도와 암묵적 태도의 예측요인이 달랐다. 이는 편견의 '표출'을 완화하는 요소를 이용해 '내적 편견'을 예측하고 개선하는 데는 한계가 있으며 따라서 암묵적 편견에 대한 별도의 접근이 필요함을 보여준다. 둘째, 어린이의 연령차별적 태도와 노인 접촉경험의 관계는 어린이와 노인의 관계특성, 그리고 접촉의 양적 측면과 질적 측면에 따라 다소 복잡한 관계를 보였다. 종합적으로 요약하면 노인을 많이 그리고 긴밀하게 만나는 아이들이 표면적으로 또는 내면적으로 연령차별적일 가능성이 낮았다. 마지막으로, 접촉질이 중요한 명시적 태도와 달리 암묵적 태도는 접촉량과 약한 관련을 보였으며, 접촉질과는 관계가 없었다. 이는 편견 완화에 접촉량보다는 질의 효과를 강조해온 집단 간 접촉이론(Intergroup contact theory)으로 설명되지 않는 결과로, 접촉의 암묵적 태도에 대한 영향을 전반적으로 검토하고 이론을 보완할 필요가 있다.

The purpose of this study was to investigate the relationship of family resilience, gratitude, and child-rearing attitude and to identify predicting factors of family resilience among mothers of young children. A correlative research design was be used for this study with self-administered questionnaires. The subjects were 248 mothers of young children from kindergarten located in Jeonnam and Gwangju provinces in Korea. Data were collected between May to June, 2013. Descriptive statistics, Pearson's correlation coefficient, and multiple regressions with PASW Statistics 18 (SPSS 18.0) program were used for data analysis. The major findings are summarized as follows: (1) Family resilience was closely related to gratitude and four types of child-rearing attitudes. Gratitude was closely related to four types of child-rearing attitudes. And rejective attitude had significantly negative relations family resilience and gratitude. (2) The significant factors affecting family resilience were mother's education level, gratitude, affective attitude, rejective attitude, autonomous attitude and controlling attitude which explained 63% of the variance. The results indicate that gratitude and child-rearing attitude were significant factors associated with family resilience among mothers of young children. In order to increase the family resilience among mothers of young children, family programs that deal with both gratitude and child-rearing attitude should be designed.

The present study purposed to examine how the knowledge, consciousness and attitude affect life resources use of the subjects, first-year middle school students and their mothers, and ultimately, to provide basic materials for maximizing the effect of the education consciousness and attitude on environment-friendly life resource management in everyday living. The followings are the results of the analysis of the collected data. First, in the aspects of analysis of valiance in the general home environment factors of this research, there were some significance according to fathers and mothers' educational level, fathers' job, the type of a house about students and mothers' life resources use. Second, knowledge about middle school students' life resources use had negative correlations with attitude. But consciousness had positive correlations with attitude. Knowledge about their mothers' life resources use had negative correlations with attitude, but consciousness had positive correlations with attitude. The results of mothers were similar to those of middle school students. Mothers' consciousness and attitude had positive correlations with middle school students' consciousness and attitude.

The study of young people's attitudes towards appearance management has special significance for understanding young people's living, thought and attitudes. It was handed out 600 questionnaires in the three cities and look 573 questionnaires back, out of which 552 were used as the basic material for the analysis. These 522 questionnaires included 178 in Beijing, 200 in Shanghai, 175 in Dalian. 154 questions in four aspects were raised in the questionnaires. The purpose of this study were to identify the Chinese generation' lifestyle and fashion attitudes. Questionnaires developed by researcher were distributed and collected from 552 chinese new generation of the three cities(178 in Beijing, 200 in Shanghai, 175 in Dalian). 1) Life attitudes of new generation men and women in China were classified into five factors, which were extravagant pleasure-seeking, sports-oriented, marriage-oriented, appearance-oriented and study-oriented attitudes. 2) Fashion attitudes of new generation men and women in China were classified into eight factors, which were fashion attitude of being conscious of others, others-dependent fashion attitude, rational fashion attitude, brand-pursuing fashion attitude, active appearance management fashion attitude, unique fashion attitude, fashion attitude of being conscious of sex role and individuality-oriented fashion attitude.

Reliable attitude estimation during the launch and early orbit phase is a critical issue for a satellite. Typically gyroscopes and other sensors are utilized to estimate the attitude during this phase. It is difficult to estimate the attitude quickly and reliably using gyroscopes because it requires a large computational load and accurate sensor measurements. Furthermore, the gyroscope failure may lead to the loss of the satellite. This paper suggests a simple attitude estimation method of a low earth orbit satellite without using gyroscopes, but only using sun sensors and magnetometers in the sun-acquisition mode. Using Kompsat-I telemetry data, we verified that the suggested algorithm provides attitude estimation within 3 degrees on each axis.

The purpose of this study was to examine the effect of consumption values on well-being attitude and the effect of well-being attitude on well-being oriented behavior. This study administered a questionnaire survey to adults between 10s and 60s who lived in Seoul, Daegu, and Kyungbuk region. Data collected from 285 respondents were analyzed by descriptive statistics, t-tests, ANOVA tests, factor analyses, and structural equation modeling (SEM). The model of the study was tested by structural equation modeling and the results of SEM revealed positive effects of social value and functional value on well-being attitude and positive effect of well-being attitude on well-being oriented behavior. The results of t-tests and ANOVA tests showed that there were significant differences in consumption values, well-being attitude, and well-being oriented behavior among marital status, age, educational level, and income level groups.

This research attempts to analyze type of typography influence on advertising attitude, brand attitude, and purchasing intention among print advertisements. Frequency analysis, reliability analysis using Cronbach's alpha, and MANOVA were utilized to analyze those gathered data. The result is the type of typography, affects on building advertising attitude in the mind of audience. However, brand attitude, and purchasing intention are not signigicant. It means that type of typography does not influence on building brand attitude and purchasing intention.
