In this work, the nutation control of rigid spacecraft with only two momentum wheels is addressed by applying the feedback linearization technique. In this strategy, the primary performance index is to regulate the nutational angle by the momentum control of wheels. The spacecraft attitude equations of motion are transformed to a general linearized form by feedback linearization technique, including a guaranteed control law promising the internal dynamics stability to accomplish the nutation angle small. It is proven that the configuration of inertia properties plays a key role in analyzing spacecraft energy level. The behavior of the momentum wheels is also studied analytically and numerically. Finally, the effectiveness of the proposed nonlinear control law for the momentum transfer is verified by conducting numerical simulations.

The purpose of this current study is to explore use of pod casting. First, the study investigated types of motivation for using pod casting. Secondly, based on theory of planned behavior, we analyzed how social norm, attitude, and self-efficacy regarding using of pod casting influence people's using behavior of pod casting. We found the four different types of motivation for using pod casting: Everyday life information, entertainment, flee from reality, and professional information. Regarding theory of planned behavior, the theory was significant model to explain use of pod casting, and self-efficacy was the most significant variable to predict use of pod casting.

The purpose of this study was to investigate the selected predictors of the health promotion behavior of the elderly in Kangseo-ku, Kangnam-ku, Seoul. The study used an ecological perspective approach in that a microsystem (i.e. self-esteem, locus of control, introversion-extraversion and socio-demographic characteristics), and the environment such as a mesosystem (i.e. marriage satisfaction) and a macrosystem (i.e. social support, participation of social activities, social image of the elderly, social attitude of the elderly) were explored. A structured questionnaire was used to interview a sample of 188 elderly. Hierarchicai regression analysis yielded the results that the magnitude of the importance of the microsystem was found to be larger than any other systems investigated. The most powerful predictor of the health promotion behavior of the elderly was 'age', followed by 'participation of social activities', 'education', 'social support', 'locus of control', 'marriage satisfaction', and 'sex'. The research model accounted for $55\%$ of the health promotion behavior of the elderly.

This paper describes the effects of slider behavior over patterned media. The flying characteristics of a slider over patterned media are different from slider flying behavior over conventional plane disk. In order to perform the most realistic simulation of slider flying characteristics over patterned disk surfaces, our simulation approach virtually distributes the grooves on the slider ABS instead of on the disk surface. Also, we define SSFA which is steady-state slider flying attitude. The results show that the more patterned size is small and height is large, the more increased SSFA is. Also if patterned distance is small, then SSFA is increased. In addition, we analyzed the effects of patterned shapes.

The effects of the COVID-19 pandemic across various sectors are far-reaching, and the education sector is not an exemption. Approved and recognized vaccines are clinically proven to provide protection and have been considered one of the primary mitigations against the virus. Knowledge, attitude, and related practices (henceforth KAP) toward the virus is widely considered to be an essential cognitive key in public health for health intervention, prevention, and promotion. Previous studies revealed a positive correlation between knowledge and attitude. This study investigated the KAP and their relationship among the 857 college students in one state college in the Philippines using an online survey. Using descriptive statistics, the findings showed that the majority of the respondents have been fully vaccinated against COVID-19. Respondents were shown to be knowledgeable about COVID-19, specifically about its transmission, clinical symptoms, treatment, risk groups, isolation, prevention, and control. Positive attitudes toward individual and governmental mitigation and control of the virus were shown. Their scores on practices revealed that they always exhibit protective and preventive behavioral practices. Pearson correlation revealed a weak significant relationship between knowledge and practice, and a fair significant relationship between attitude and practice. No significant relationship is found between knowledge and attitude. This study hopes to find its place in the literature worthy of consideration as empirical support toward understanding a specific group's perceptive risk and preventive behavior toward the virus, policy making, and health intervention and promotion.

The purpose of this study was to investigate the effects of alcohol intake on nutritional intake status among the college students. The subjects were divided three groups; no-alcohol group(n=78), alcohol group(n=113), and high-alcohol group(n=82) according to intake and frequency of alcohol. And they were observed characteristics of alcohol drinking, dietary behavior and attitude, and nutrient intakes using questionnaires. The frequency of skipping meals in breakfast in high-alcohol group were higher than in other two groups(p<0.01). There were no significant differences in frequency of skipping meals of lunch and supper, reason why skipped meals, and total score of dietary attitude among three groups. However, the score of dietary attitude about no heavy drinking and smoking in high-alcohol group was higher than in other two groups(p<0.01). There were significant difference in vitamin B2 intake, alcohol intake, and energy intakes from carbohydrate, lipid, and alcohol among three groups(p<0.05, p<0.05, p<0.01, p<0.05, p<0.05). Compared energy intake of high-alcohol group with other two groups, intake from carbohydrate was low and intakes from lipid and alcohol were high. In the nutrient density, plant protein and carbohydrate in no-alcohol group, lipid and vitamin B2 in alcohol group, and animal lipid in high-alcohol group were highest among three groups. NAR and MAR were not significant difference among three groups except that NAR of P in alcohol group is highest among three groups(p<0.05). In conclusion, students high consuming alcohol have unhealty dietary behaviors in the light of high frequency of skipping breakfast, undesirable dietary attitude of alcohol drinking and smoking, and low energy inake from diet. Therefore, this results should be considered in meal management and nutritional education for student of high alcohol consumption.

Background: Initiation, perpetuation and cessation of smoking are all multifactorial. It is essential to explore interactions among various parameters influencing smoking and its cessation for effective smoking cessation interventions. Objectives: To obtain insights into smoking and its cessation among current smokers in India. Materials and Methods: The present study was conducted among current smokers visiting the Department of Oral Medicine and Radiology, Manipal College of Dental Sciences (MCODS), Manipal University, Mangalore. Knowledge, attitudes, behavior, worksite practices towards smoking and its cessation, barriers to smoking cessation and socio-demographic variables were explored using a structured, pretested, self-administered questionnaire. Results: A total of 175 current smokers participated in the study. Mean knowledge, attitude, worksite practice and barrier scores were $15.2{\pm}5.67$ (66.1%), $57.5{\pm}7.67$ (82.1%), $4.18{\pm}2.02$ (41.8%) and $57.4{\pm}12.37$ (63.7%) respectively. Correlation analysis revealed: association of knowledge with education, occupation and religion; attitude with education and occupation; worksite practices with occupation; knowledge with attitude; and barriers negatively with worksite practices. The majority (85.7%) of respondents intended to quit smoking and this was associated with higher attitude scores, whereas actual quit attempts were associated with high knowledge, attitudes, worksite practices and low barrier scores. Conclusions: Various socio-demographic factors associated with smoking and its cessation were identified. The present study highlights the importance of identifying and targeting these interactions while framing guidelines and interventions for effective tobacco cessation in a developing country like India.
