Removing a limited number of large debris can significantly reduce space debris risks. These bodies are generally exposed to extreme environmental disturbance torques or consecutive accidents due to their large wet area, which causes them to experience accelerated high-rate tumbling motion. The existing literature has adequately explored the approximation operations with non-cooperative targets exhibiting 3-axis tumbling motion. However, the research gap lies in the lack of attention given to addressing this approximation for targets undergoing accelerated motion. Agile, accurate, and large-angle maneuvers are three common necessities for safely capturing such targets. Changes in the moment of inertia brought on by fuel slushing cannot be disregarded during such a maneuver. To deal with nonlinearities, adverse coupling effects, actuator saturation constraints, time-varying moment of inertia, and external disturbances that worsen during accelerated agile large-angle maneuvers, a novel adaptive control approach is developed in this paper. The controller's main advantage is its adjustable desired acceleration, which maintains its performance even when dealing with accelerated motion. The control law is directly synthesized from the nonlinear relative equations of motion, without any linearization or simplification of the system dynamics, making it robust to a variety of orbital elements and target behaviors. Adaptation laws are extracted from the Lyapunov stability theorem in a way that guarantees asymptotic stability. Moreover, control actuator roles (delay, saturation, and allocation) are accounted for in modeling and simulation. Finally, a comprehensive numerical simulation based on three different realistic and strict scenarios is carried out to demonstrate the effectiveness and performance of the proposed control approach. The controller's robustness against time-varying dynamic parameters (sharp and sudden change, smooth and slow change, and periodic change) is extensively demonstrated through simulation.

A novel interval valued p,q Rung orthopair fuzzy (IVPQ-ROF) multiple attribute group decision making (MAGDM) method for sustainable supplier selection (SSS) is proposed in this paper. This study mainly contains two research points: (1) tackling the interrelation between attributes; and (2) describing the psychological state and risk attitude of decision makers (DMs). For the first research point, we introduce the Archimedean operation rules for interval valued p,q Rung orthopair fuzzy sets (IVPQ-ROFSs), then the generalized interval valued p, q Rung orthopair fuzzy Maclaurin symmetric mean (GIVPQ-ROFMSM) operator and the generalized interval valued p, q Rung orthopair fuzzy weighted Maclaurin symmetric mean (GIVPQ-ROFWMSM) operator are defined to reflect the correlation between attributes. For the second research point, we introduce the positive ideal degree (PID) and negative ideal degree (NID) based on projection of IVPQ-ROFSs, and modified regret theory. Both of them consider the best alternative and worst alternative, so as to reflect the psychological state and risk attitude of DMs. Finally, a SSS problem is presented to manifest the effectiveness of the designed method. We also provide sensitivity analysis and comparative analysis to further demonstrate the rationality and validity of the proposed method.

AIM
To assess oral health-related knowledge, attitude, and practices (KAP) of patients with diabetes mellitus (DM) attending public diabetic clinics in Dar es Salaam, Tanzania.
METHODOLOGY
This study involved adult patients diagnosed with DM. A questionnaire with questions related to oral health KAP was used. Data analysis was done using SPSS software v26. Multivariate regression analysis was utilized for response analysis. An alpha of less than 0.05 was considered to indicate statistical significance.
RESULTS
Participants with good levels of KAP related to oral health comprised 51.0%, 82.3%, and 20.6%, respectively. The odds of good oral health knowledge among participants were almost 2 folds higher in participants with high education levels and 7 folds higher in those who had been referred to a dentist by a physician. Participants with good oral health knowledge had 5.5 times higher odds of having a good attitude. The participants with high education levels were almost 3 times more likely to have good practice.
CONCLUSION
About half of the patients with DM have good oral health-related knowledge. A majority have good compliance towards oral health, but only a limited number have good oral health-related practices. The level of education and previous referrals to dental professionals were found to be predictors of good knowledge regarding dental health.

OBJECTIVES
Intravenous medication errors continue to significantly impact patient safety and outcomes. This study sought to clarify the complexity and risks of the intravenous administration process.
DESIGN
A qualitative focus group interview study.
SETTING
Focused interviews were conducted using process mapping with frontline nurses responsible for medication administration in September 2020.
PARTICIPANTS
Front line experiened nurses from a Japanese tertiary teaching hospital.
PRIMARY AND SECONDARY OUTCOME MEASURES
The primary outcome measure was to identify the mental models frontline nurses used during intravenous medication administration, which influence their interactions with patients, and secondarily, to examine the medication process gaps between the mental models nurses perceive and the actual defined medication administration process.
RESULTS
We found gaps between the perceived clinical administration process and the real process challenges with an emphasis on the importance of verifying to see if the drug was ordered for the patient immediately before its administration.
CONCLUSIONS
This novel and applied improvement approach can help nurses and managers better understand the process vulnerability of the infusion process and develop a deeper understanding of the administration steps useful for reliably improving the safety of intravenous medications.

Cancel culture is a prevalent boycotting practice used to exert pressure, express disapproval, and enforce consequences online. While multiple studies have been done on cancel culture's history, evolution, and effects, none of them were focused on Cancel Culture for Gen Z, the most socially aware and digitally inclined generation. The study aimed to uncover the factors that influence Gen Z's intention to participate and actual participation in cancel culture by utilizing a newly established integrated framework of Belief in a Just World (BJW) and the Theory of Planned Behavior (TPB). A total of 677 valid survey responses from Gen Z respondents were collected to thoroughly evaluate the belief and behavioral dimensions of cancel culture through the utilization of Structural Equation Modeling (SEM). The study's results showed that attitude towards cancel culture, the subjective norm of cancel culture, and perceived behavioral control, are strong facilitating conditions that drive Gen Z's intent and actual participation in canceling behavior. It was seen that BJW has no effect on actual canceling behavior and a reverse effect on the intention to participate in canceling behavior. For the canceling methods, 97 % will unsubscribe or unfollow accounts and 94.68 % will block or mute accounts. It was also discovered that Facebook, Instagram, and YouTube are the top social media platforms used by Gen Zs in the Philippines with at least a 94 % usage rate. The findings of this study may be utilized by businesses and policymakers on how to reduce the incidence and impact of cancel culture.

OBJECTIVE
Since negative emotions were identified as barriers to HIV self-testing (HIVST), offering emotional support may promote this behavior. This study examined whether the socio-affective and reappraisal components of emotional support messages differ in affecting one's attitude towards and intention to conduct HIVST via response efficacy and self-efficacy.
METHOD
A between-subject online experiment was conducted with 309 Chinese men who have sex with men. Participants were randomly assigned to one of three conditions: no support, only reappraisal information, socio-affective and reappraisal information both provided.
RESULTS
Emotional support only worked for those completing HIVST in recent three months. The reappraisal information enhanced their response efficacy and self-efficacy, but only self-efficacy was positively related to one's attitude towards and intention to conduct HIVST. The message including socio-affective and reappraisal components directly improved their HIVST-related attitudes.
CONCLUSION
Emotional support presents an approach to promoting HIVST. The socio-affective and reappraisal information function differently on their response efficacy, self-efficacy, attitude, and intention.
PRACTICE IMPLICATIONS
This study provides implications on how to design messages promoting HIVST for health campaigns and AI-based healthcare technologies. Reappraisal information should be offered to enhance one's response efficacy and self-efficacy. Messages should address both socio-affective and reappraisal needs of individuals.

BACKGROUND
Educational inclusion of students with disabilities has benefits for students with and without disabilities. However, general classroom education remains inaccessible for students with disabilities in Saudi Arabia despite policy reforms in the country.
AIM
To examine the perspectives of parents of children with and without disabilities on inclusion in general education classrooms.
METHODS AND PROCEDURES
A cross-sectional survey investigated parents' (N = 225) perspectives on inclusion in general and across four dimensions, namely impact on students with and without disabilities, and on parents and families of students with and without disabilities.
OUTCOMES AND RESULTS
Although all participants support inclusion, parents of students with disabilities agreed more strongly with statements supportive of inclusion than parents of students without disabilities. Parents of students with severe disabilities expressed the least agreement with statements supporting inclusion.
CONCLUSIONS AND IMPLICATIONS
All parents supported inclusion but were concerned about the preparation and provisioning of teachers as a key factor in the success of inclusion.

Randomized Controlled Trial
BACKGROUND
Hypertension is one of the most important cardiovascular disease risk factors and affects >100 million American adults. Hypertension-related health inequities are abundant in Black communities as Black individuals are more likely to use the emergency department (ED) for chronic disease-related ambulatory care, which is strongly linked to lower blood pressure (BP) control, diminished awareness of hypertension, and adverse cardiovascular events. To reduce hypertension-related health disparities, we developed MI-BP, a culturally tailored multibehavior mobile health intervention that targeted behaviors of BP self-monitoring, physical activity, sodium intake, and medication adherence in Black individuals with uncontrolled hypertension recruited from ED and community-based settings.
OBJECTIVE
We sought to determine the effect of MI-BP on BP as well as secondary outcomes of physical activity, sodium intake, medication adherence, and BP control compared to enhanced usual care control at 1-year follow-up.
METHODS
We conducted a 1-year, 2-group randomized controlled trial of the MI-BP intervention compared to an enhanced usual care control group where participants aged 25 to 70 years received a BP cuff and hypertension-related educational materials. Participants were recruited from EDs and other community-based settings in Detroit, Michigan, where they were screened for initial eligibility and enrolled. Baseline data collection and randomization occurred approximately 2 and 4 weeks after enrollment to ensure that participants had uncontrolled hypertension and were willing to take part. Data collection visits occurred at 13, 26, 39, and 52 weeks. Outcomes of interest included BP (primary outcome) and physical activity, sodium intake, medication adherence, and BP control (secondary outcomes).
RESULTS
We obtained consent from and enrolled 869 participants in this study yet ultimately randomized 162 (18.6%) participants. At 1 year, compared to the baseline, both groups showed significant decreases in systolic BP (MI-BP group: 22.5 mm Hg decrease in average systolic BP and P<.001; control group: 24.1 mm Hg decrease and P<.001) adjusted for age and sex, with no significant differences between the groups (time-by-arm interaction: P=.99). Similar patterns where improvements were noted in both groups yet no differences were found between the groups were observed for diastolic BP, physical activity, sodium intake, medication adherence, and BP control. Large dropout rates were observed in both groups (approximately 60%).
CONCLUSIONS
Overall, participants randomized to both the enhanced usual care control and MI-BP conditions experienced significant improvements in BP and other outcomes; however, differences between groups were not detected, speaking to the general benefit of proactive outreach and engagement focused on cardiometabolic risk reduction in urban-dwelling, low-socioeconomic-status Black populations. High dropout rates were found and are likely to be expected when working with similar populations. Future work is needed to better understand engagement with mobile health interventions, particularly in this population.
