Microstructure evolution and tensile behavior of balanced Al−Mg−Si alloy with various homogenization parameters

The effects of homogenization parameters on the microstructure evolution and tensile behavior of a balanced Al−Mg−Si alloy were investigated using the optical microscope,scanning electron microscope,X-ray diffraction,electron probe microanalyzer,differential scanning calorimetry,electrical conductivity test,and tensile test.The results show that Mg_(2)Si andβ-AlFeSi are the main intermetallic compounds in the as-cast structure,and Mg solute microsegregation is predominant inside the dendrite cell.The prediction of the full dissolution time of Mg_(2)Si by a kinetic model is consistent with the experiment.Theβ-AlFeSi in the alloy exhibits high thermal stability and mainly undergoes dissolution and coarsening during homogenization at 560℃,and only a small portion is converted toα-AlFeSi.The optimal homogenization parameters are determined as 560℃and 360 min,when considering the evolution of microstructure and resource savings.Both the strength and ductility of the alloy increased after homogenization.

AIDS-Related Knowledge, Attitudes and Behavior Survey among the “Migrant” Population in China

Objective To realize AIDS related knowledge, attitude and behavior among floating people in China and discuss its influencial factors, and to provide the evidence for how to prevent AIDS in floating population. Methods The data were collected from the ＂Sex and Reproductive Health Baseline Survey among Floating People in China＂ conducted in March 2004. The standard questionnaires were used to interview altogether 4 900 floating people from 6 provinces. Results Nearly 95.4 % of them had heard about AIDS, but only 0.5% can judge all the transmitted ways and no-transmitted ways correctly, 45.9 % believed that we need to isolate the HIV positive people. Only 65.7% knew that using condom can preventive HIV infection, 43. 7% showed their understanding about the man who has long time no sexual life has sex with a sexual worker. About 13.6% floating people chose condom as FP method and among them only 34. 6% used condom every time. Conclusion Chinese floating people are lack of AIDS knowledge. Most of them do not practise Safe Sex Activity. We need to give more intervention to the floating population.

The Effect of Contact-Based Interventions on the Attitudes and Behaviors of Nursing Students towards People with Mental Illness: A Literature Review

Background: Student nurses and other healthcare students are the future mental health professionals and have the potential for changing the future of mental healthcare. Therefore, their negative attitudes and behaviors should be screened and corrected by effective anti-stigma interventions. Otherwise, they would likely withhold some health services and practice coercive treatments once planning care to people with mental illness. However, little is known on effective approaches to correct these negative attitudes and behaviors, despite the previous reviews that have shown that contact-based interventions have demonstrated positive attitudinal and behavioral changes for nursing students towards people with mental illness. Aim: The aim of this literature review was to compile the available research evidence on contact-based interventions that have targeted the attitudes and behaviors of nursing students towards people with mental illness. Methods: The relevant literature was extracted by searching electronic databases (MEDLINE, PsycINFO, and CINAHL) and by hand checking reference lists of past similar reviews. Results: Eleven studies were retrieved and included in this review. The included studies in this review either have employed social contact interventions, video-based social contact interventions, or both types for the aim of combining or comparing. Furthermore, the included studies either have targeted the attitudes of nursing students towards people with mental illness (including prejudice), or a combination of attitudinal and behavioral outcomes (including behavioral intentions and social distance). No studies have targeted behavioral outcomes solely. Conclusions: From the available literature, the current authors cannot draw conclusions on the most effective type, form, or ingredients of contact-based interventions among nursing students, as previous literature has large variations. No consistency was found in the previous studies regarding the types or contents of effective contact-based interventions. The compiled evidence in this review, has suggested that contact-based interventions (both social contact and video-based social contact) have been effective in changing the attitudes and behaviors of nursing students favorably, similarly to what previous reviews have found.

A Comparison of the Sexual Knowledge, Attitudes, and Behaviors of Korean College Students Studying in Korea and in the United States

The number of Korean students enrolling in universities overseas is rapidly growing. However, these populations are underrepresented in sexuality related research, despite the possibility of sexually risky behavior in overseas university students. We examined the sexual knowledge, attitudes, and behaviors of university students in Korea and studying in the United States. Data were collected—131 Korean students in Korea and in the US using a web-based self-report questionnaire system. Students in the US showed greater total sexual knowledge than students studied in Korea. There were differences in the sexual knowledge, attitude and behaviors according to general characteristics between both groups. Although students in the USA had a higher level of sexual knowledge, both students in the USA and in Korea had a low level of sexual knowledge overall.

Food Sanitation Knowledge, Attitude, and Behavior for the University Restaurants Employees

The purpose of this study was to discuss the food sanitation knowledge, attitude, and behavior for the employees of university restaurants, and furthermore, to explain the interrelations of these various were occurring at school. A questionnaire survey procedure was used. Each two constructs of food sanitation attitude and behavior were analyzed by factor analysis. Data was analyzed by description, Pearson’s correlation and multiple regression analysis. The correctness rate toward the whole sanitation knowledge of trials was 70%. The overall attitude toward food sanitation was prone to positive and the attitude of employee self-responsibility was superior to the attitude of food sanitation practice. The sanitary guiding behavior was better than the sanitary habit behavior;and there was a significant relationship indicated through Pearson correlation analysis among three various. The sanitation knowledge and sanitation attitude showed a 42.6% predictive power to behavior, the attitude was mediated between knowledge and behavior. The university restaurant employees shared a more pessimistic view toward the benefits of training and the institutions could establish a committee for monitoring food nutrition and sanitation. It provides valuable information for development employees training while seeking to raise school restaurant food safety levels.

Assessment of Environmental Health Knowledge, Attitude and Behavior among High School Students in a USA Southeast Texas School District

This cross-sectional descriptive study assessed general environmental health literacy among students focusing on their knowledge, skills, attitudes and behaviors regarding the environmental health, stewardship, and sustainability, using a questionnaire consisting of 35 core questions from the Centers for Diseases Control (CDCs). Students (N = 185) from three high schools in the district were asked through their class teachers to voluntarily complete the questionnaire. Results indicated that about 41% (n = 77) of the students lacked knowledge regarding potential sources of radiation exposure and 70% (n = 133) lacked knowledge regarding radon gas being the number one risk factor for lung cancer among non-smokers. Additionally, the ANOVA test indicated significant knowledge differences among school location. Students in school #1, located in the most affluent area, had significantly higher knowledge scores (M = 4.39) than school #2 located in a moderately affluent area (M = 3.50). Furthermore, we found significant differences in ethnicity on the environmental health attitude of the high school students. Black students reported lower positive environmental health attitude (M = 29.86) than White students (M = 32.63), Hispanic students (M = 32.33) and Asian students (M = 33.84). These findings demonstrated knowledge deficiency in some key areas in environmental health particularly the environmental diseases and conditions caused by manmade hazards such as pesticides, chemicals, radiation, air, water, and soil pollution. Targeted educational interventions to increase awareness and understanding of health effects, exposure to environmental hazards and carcinogens as well as risks associated to direct exposure as in this study, radon and radiation, should be provided to high school students. Practical education through tours where students can observe directly and participating in laboratory experiments could empower the students to translate this knowledge into positive environmental health behaviors and practices now and in the future.

Sanitation in Urban Slums： Perception, Attitude and Behavior： The Case of Kibera, Nairobi-Kenya

Over 60 percent of Kenya＇s urban dwellers live in slum settlements. Here, people live under life-threatening conditions characterized with poverty, inadequate food and shelter, physical overcrowding, unsafe drinking water and poor sanitation. The flimsiness of these dwellers is not always due to low incomes. It is often the result of insecurity of tenure and other deprivations： the lack of entitlement inhibits their investment in better health. In Kibera Slum, Africa＇s second largest and Kenya＇s oldest and largest slum, poor sanitation and inadequate water supply is a daily challenge for the residents. Over 150 persons share one shallow pit latrine while 75 percent of the population uses sanitation practices that involve direct handling of human waste increasing in spread of infectious diseases. Insecurity of tenure; low levels of education; inadequate socio-economic, infrastructural and physical entitlements all affect the Kibera＇s residents＇ perception and attitude towards investing in better sanitation behavior.

Attitudes Toward Dysfunctional Audit Behavior： The Effect of Budget Emphasis, Leadership Behavior, and Effectiveness of Audit Review

Dysfunctional audit behavior （DAB） is an accepted problem, associated with decreased audit quality. This study develops and tests a theoretical model that identifies factors contributing to DAB. Budget emphasis, leadership behavior structure and consideration, and effectiveness of audit review were examined as antecedents of attitudes toward DAB. The findings produced consistent evidence in support of the theoretical model. It is not an emphasis on meeting budgets that leads to undesirable behavior, but contextual variables, such as leadership behavior structure and effectiveness of audit review.

The Influence of Tourists＇ Attitude and Self-efficacy Belief in Adopting Responsible Behavior in Bangladesh

This research examined tourists＇ intention to adopt responsible behavior （RB）. Toward this, two constructs of determinants （attitude and self-efficacy belief） of intention to adopt RB were identified through literature surveys. Also, three constructs of RB alternatives, namely, economically RB （ECNRB）, environmentally RB （ENVRB）, and socio-culturally RB （SCLRB）, were identified through a focus group discussion. A self-administrated questionnaire was surveyed among 351 professionals in Bangladesh. Confirmatory factor analysis of both the independent and dependent variables was done prior to employing them in the structured equation model to validate the model and test the hypotheses. The research found that in Bangladesh, the self-efficacy belief influences tourists＇ intention to choose RB more than the attitude does, but their influences on tourists＇ intention to adopt ECNRB, ENVRB, or SCLRB are varied. Moreover, tourists were found to have less intention to adopt ECNRB than ENVRB and SCLRB. For the policy makers or promoters of responsible tourism （RT）, those who want to promote any kind of RB in Bangladesh need to increase self-efficacy belief among tourists. The policy makers need to develop themes around tourists＇ positive experience, emotional and physiological states along with verbal persuasion in their communication messages （Bandura, 1997） and in any kind of interpretations at the destination whilst targeting a particular market segment.

How Environmental Attitudes Affect Consumers’Willingness to Engage in Green Consumption Behaviors:The Moderating Role of“Plastic Restriction”

Consumers’willingness to engage in green consumption behavior will be guided by internal psychological factors and also influenced by external environmental factors.One of the most common external interventions is the issuance of scientific policies and regulations.The government may introduce policies and regulations that help to increase the willingness of green consumption behavior,such as energy-saving and emission reduction policies and policies to restrict plastic products.In this paper,the authors study the mechanism of the effect of environmental attitudes on consumers’willingness to engage in green consumption behavior from the perspective of“plastic restriction”,and conclude that the magnitude of the effect of policies and regulations on the willingness to engage in green consumption behavior varies significantly at different levels of environmental attitudes.This study provides scientific implementation ideas and targeted management suggestions for the government to formulate effective external intervention policies for green consumption.

Coupling Relationship Analysis on Households′ Production Behaviors and Their Influencing Factors in Nature Reserves:A Structural Equation Model

A households′production behavior directly influences the quality of the environment and determines the successful development of nature reserves.Meanwhile,the households′production behaviors are complicated by interrelated factors,such as protection attitudes,resource endowment,and family wealth.This research evaluated households near the Crested Ibis National Nature Reserve in Shaanxi Province,acquiring data from 436 households around Yang County and Ningshan County in the south slope of Qinling Mountains,China.Based on the collected data,we developed a structural equation model to evaluate the coupling relationships among households′ protection attitudes,production behaviors,resource endowment,and family wealth.The results showed that:1) households with great resource endowment had more negative attitudes,probably due to their greater protection costs;2) the households with higher education levels had worse protection attitudes;3) the households with more family wealth were likely to use fewer fertilizers,pesticides,and firewood;4) the households with more resource endowment showed less production and management behaviors;5) the enhancement of households' attitudes improved production behaviors to protection the environment,but the effects were not statistically significant.Our results provide a basis for the government's protection policy making,exploring the effective management measures that are beneficial for both nature reserve management and community development.

Investigation of the Oral Health Status of Patients Based on Rehabilitation Nursing

Objective: To investigate the current situation of knowledge, attitude, and practice (KAP) of oral health among rehabilitation nursing patients, and provide some reference for implementing oral health intervention measures for rehabilitation nursing patients. Method: A total of 231 nursing patients in the rehabilitation department of a tertiary hospital in this city from January 2023 to October 2023 were selected as the research subjects. Their oral health knowledge, attitudes, and behaviors were investigated, and the oral health behavior habits of patients with different genders, education levels, and disease situations were compared. Result: The total awareness rate of oral health knowledge among patients was 73.16%, and the average score of oral health knowledge was 6.58 ± 1.25 points. The overall positive rate of oral health attitude among patients is 55.70%, and the average score of oral health attitude is 5.01 ± 1.04 points. The average score for oral health behavior is 16.87 ± 5.23 points. Only 8.48%, 3.3%, 1.3%, 2.6%, and 0.87% of patients seek timely medical treatment for bleeding tooth roots, gum swelling and pain, gum bleeding, tooth pain, and dental calculus, respectively;Only 5.19% of people change their toothbrush every 3 months, and only 10.39% use the vertical brush method to brush their teeth. The scores of oral health knowledge, attitudes, and behaviors of patients are related to age, educational level, disease type, and smoking situation. The oral health knowledge and attitude scores of elderly patients were lower than those of younger patients, and the difference was statistically significant (P P P P P < 0.05). Conclusion: The oral health status of rehabilitation nursing patients is not optimistic, with a moderate level of oral health knowledge, weak awareness of oral health, and a low qualification rate of oral health behaviors. Strengthening oral health education for rehabilitation nursing patients and incorporating oral health care procedures into rehabilitation nursing procedures is of great significance.

Household behavior in practicing mental budgeting based on the theory of planned behavior

Ajzen’s theory of planned behavior(TPB)suggests that planned behavior is determined by behavioral intention.Despite extensive literature based on TPB,household mental budgeting behavior explained by TPB is underexplored.The current study empirically tested TPB factors in light of mental budgeting behavior.The hypothesized model was tested using partial least squares structural equation modeling(PLS-SEM).PLS-SEM was employed using a Likert-scaled questionnaire administered to 275 households.The results indicate that mental budgeting attitude and mental budgeting past behavior strongly predict mental budgeting intention,and mental budgeting intention predicts mental budgeting behavior.Further,mental budgeting intention partially mediates the relationship between mental budgeting attitude and mental budgeting behavior,and mental budgeting past behavior and mental budgeting behavior.This study contributes to the academic interest in theoretical progress in household behavior.

Depressive Symptoms and Food Intake among Weight-Preoccupied Women: Do Eating Behaviors and Attitudes or BMI Mediate This Association?

Associations between depressive symptoms, dysfunctional eating behaviors and attitudes, higher food intake and body mass index (BMI) have been previously observed. However, few studies have assessed these variables in the same study. The first objective is to compare, in a natural setting environment, the profile of women reporting lower or higher levels of depressive symptoms in terms of food intake, eating behaviors and attitudes, and BMI. The second objective is to test mediational models for which the link between depressive symptoms and food intake would be mediated by eating behaviors and attitudes or BMI. Weight-preoccupied women were recruited (n = 323), and their level of depressive symptoms was assessed using the Beck Depression Inventory. The median score was used to create two groups (lower ≤ 13;higher > 13). A web-based food-frequency questionnaire, the Three-Factor Eating Questionnaire, and the Intuitive Eating Scale were completed. BMI was calculated from reported body weight and height. Compared to women with a lower level of depressive symptoms, those with a higher level of depressive symptoms reported a higher energy intake (p = 0.02), and a higher consumption of savoury foods (p = 0.02). These women also had higher scores of disinhibition (p p = 0.0002), ate less intuitively (p p = 0.005). Association between depressive symptoms and energy intake was mediated by disinhibition, susceptibility to hunger and eating for physical rather than emotional reasons, while the role of BMI was less clear. Regarding another component of food intake, association between depressive symptoms and consumption of savoury foods was mediated by disinhibition and eating for physical rather than emotional reasons. In summary, it seems essential to be aware of the presence of depressive symptoms and to pay attention to eating behaviors and attitudes in interventions among weight-preoccupied women.
