Morning Exercise at School and Sedentary Activities are Important Determinants for Hypertension in Adolescents

Background: This study was performed to determine the association of Pre–hypertension/hypertension (pre-HTN/HTN) with leisure-time activities and morning exercise at school in a sample of Iranian adolescents. Methods: This secondary study has done using data of 1992 adolescents participated in of Isfahan Healthy Heart Program. The outcome variable was having/not having pre-hypertension/hypertension (pre-HTN/HTN). The students with Blood pressure (BP) between 90th to 95th percentiles were considered as positive pre-HTN and students with BP >95th percentile were considered as positive HTN. Students with pre-HTN or HTN were considered as positive pre-HTN/HTN. The asked leisure-time activities were categorized in three group including first (ping-pong, basketball, and volleyball), second (football, walking, and bicycling) and sedentary activities (watching TV, studying, and computer gaming), using factor analysis. Results: The prevalence of pre-HTN and HTN was 16.1% and 6.7%, respectively. Based on multiple logistic regression pre-HTN/HTN was associated just with sedentary activities and morning exercise at school. Odds Ratio (95% confidence interval) for sedentary activities and morning exercise at school was 1.51 (1.13–2.01) and 0.63 (0.44–0.89), respectively. Conclusion: We observed adolescents who engaged in morning exercise at school had lower prevalence of HTN while those who spent more times on sedentary activities were in higher risk for HTN. We suggest to permanent holding of morning exercise and educational programs on healthy lifestyle skills for adolescents by schools.
What have we learned about what works in sustaining mental health care and support services during a pandemic? Transferable insights from the COVID-19 response

Efforts have been made to adapt the delivery of mental health care and support services to the demands of COVID-19. Here we detail the perspectives and experiences of mental health workers (MHWs), in relation to what they found helpful when adapting mental health services during the COVID-19 pandemic and responding to its demands. We were interested in exploring what has helped to support MHWs’ own health and wellbeing given that staff wellbeing is central to sustaining the delivery of quality mental health services moving forward. Individual interviews were conducted with MHWs (n = 30) during the third COVID-19 lockdown. Interviews were audio-recorded, transcribed and managed using NVIVO. Qualitative data was analyzed using an inductive thematic approach. Three major themes were created, which emphasized the importance of: (1) 'self-care and peer support (checking in with each other)', (2) 'team cohesion and collaboration' and (3) 'visible and supportive management and leadership (new ways of working)'. Our findings emphasize the importance of individual, team and systems-based support in helping MHWs maintain their own wellbeing, whilst adapting and responding to the challenges in providing mental health care and support during this pandemic. Guidance and direction from management, with adaptive leadership in providing sustained, efficient, and equitable delivery of mental healthcare, is essential. Our findings support future policy, research and mental health practice developments through sharing important salutogenic lessons learned and transferable insights which may help with preparedness for future pandemics.
The Culture of Safety on Australian Farms

Abstract The concept of developing a culture of safety in industry is becoming more important in the prevention of occupational injury and death. Little information is available on the safety culture in farming even though injury and death rates in this industry are some of the highest in Australia. This paper explores the attitudes and beliefs of a small sample of farmers regarding the development of a safety culture and investigates their reluctance to adopt State regulations for occupational health and safety. Findings reveal that, while a culture of safety exists, farmers define this in a way that reflects their autonomy and socially constructed identity. Economic pressures drive the culture, on the one hand, and the experience of injury on the other.
Handling Imbalanced Datasets for Robust Deep Neural Network-Based Fault Detection in Manufacturing Systems

Over the recent years, Industry 4.0 (I4.0) technologies such as the Industrial Internet of Things (IIoT), Artificial Intelligence (AI), and the presence of Industrial Big Data (IBD) have helped achieve intelligent Fault Detection (FD) in manufacturing. Notably, data-driven approaches in FD apply Deep Learning (DL) techniques to help generate insights required for monitoring complex manufacturing processes. However, due to the ratio of instances where actual faults occur, FD datasets tend to be imbalanced, leading to training challenges that result in inefficient DL-based FD models. In this paper, we propose Dual Logits Weights Perturbation (DLWP) loss, a method featuring weight vectors for improved dataset generalization in FD systems. The weight vectors act as hyperparameters adjusted on a case-by-case basis to regulate focus accorded to individual minority classes during training. In particular, our proposed method is suitable for imbalanced datasets from safety-related FD tasks as it generates DL models that minimize false negatives. Subsequently, we integrate human experts into the workflow as a strategy to help safeguard the system. A subset of the results, model predictions with uncertainties exceeding a preset threshold, are considered a preliminary output subject to cross-checking by human experts. We demonstrate that DLWP achieves improved Recall, AUC, F1 scores.
Spray chamber evaluation of air-assisted spraying on potato plants.

This article reports on a study of air-assisted spraying where the effects of air speed, airflow rate, and air jet orientation were isolated. The study was carried out in a spray chamber. A carriage supporting a standard spray boom was moved at 6 km/h over micro-plots of greenhouse grown potato plants. Air was delivered slightly behind the nozzles from a variable width slot producing a uniform two-dimensional air jet that was adjustable in tilt in the direction of travel. Experiments were carried out using a central composite design (CCD). Compared to a full factorial design, this design required fewer experiments and allowed one to find the optimum operating conditions. The range of the independent variables was: air speed, 0 to 36 m/s; airflow, 0 to 1.3 m 3 /s/m, and air jet angle, –10.2 to 40.2°. Two sets of flat fan nozzles (VMD = 230 and 400 µm, both delivering 250 L/ha at 6 km/h) were used to carry out two full sets of experiments. Results showed that air speed had the larger impact on leaf coverage. Higher air speeds (> 25 m/s) increase the coverage on the underside of the leaves at all levels within the canopy and on the top side of the leaves in the lower third of the canopy. However, lower air speeds (< 20 m/s) are desirable for a better coverage on the top side of the leaves in the higher two-thirds of the canopy. Based on data presented here, the use of an air speed higher than 25 m/s coupled with an air jet angle of 20° forward and a fine spray increase both the coverage of hidden parts of the plants and the spray penetration towards the bottom of the canopy. Airflow rate affected coverage significantly only in conjunction with finer spray.
Low-frequency noise of InP/InGaAs heterojunction bipolar transistors

The equivalent base noise SI/sub b/ of InP/InGaAs heterojunction bipolar transistors (HBT's) with a circular pattern emitter is investigated experimentally at a low frequency ranging from 10-10/sup 5/ Hz. The measured SI/sub b/ exhibits the 1/f dependence in an overall frequency range without any accompanying burst noise. Furthermore, SI/sub b/ varies as I/sub b//sup /spl gamma// for the base current I/sub b/ and as d/sup -2/ for the emitter diameter d, where the value of /spl gamma/ ranges from 1.62-1.72 depending on d of HBT's used. The 1/f noise model, which rigorously deals with the recombination current at the base surface I/sub bs/ as a function of I/sub b/ as well as of d is proposed. Applying our noise model to the dependence of SI/sub b/ on I/sub b/, as well as on d, reveals that even though /spl gamma/ is less than two, the origin of SI/sub b/ is due to the recombination of electrons at the exposed base surface near the emitter edges. On the basis of theoretical considerations for the diffusion length of electrons and traps at the base surface, the Hooge parameter /spl alpha//sub H/ for the noise due to the base surface recombination is deduced to be in the order of 10/sup -2/ for the first time.

Appetite and Satiety Effects of the Acute and Regular Consumption of Green Coffee Phenols and Green Coffee Phenol/Oat β-Glucan Nutraceuticals in Subjects with Overweight and Obesity

Green coffee has weight management properties, yet its effects on appetite and satiety remain unclear as few, mainly acute, studies perform objective measurements. Therefore, the influence on appetite/satiety of acute and regular consumption of two nutraceuticals, a decaffeinated green coffee phenolic extract (GC) alone or combined with oat β-glucans (GC/BG), with known satiating properties, has been analysed subjectively using visual analog scales (VAS) and objectively measuring actual food intake and postprandial appetite and satiety hormones. A randomised, cross-over, blind trial was carried out in 29 overweight volunteers who consumed GC or GC/BG twice a day for 8 weeks. After acute (day = 0) and regular consumption (day = 56) of the nutraceuticals, satiety was measured at 30, 60, 90, 150, and 210 min, as well as food intake at breakfast (30 min) and lunch (300 min). Additionally, in a subgroup of participants (n = 9), cholecystokinin, peptide-YY, glucagon-like-peptide-1, ghrelin and leptin concentrations were analysed in blood samples taken at the same time-points. According to VAS results, GC/BG reduced hunger more efficiently than GC. However, there were no statistically significant differences in food intake. Comparing the effects of the acute consumption of GC/BG and GC, leptin concentration at 150 min was higher after GC/BG intake vs. GC. Moreover, when comparing the effects of regularly consuming the two nutraceuticals, maximum ghrelin level decreased with GC/BG vs. GC. In conclusion, acute and regular effects of the nutraceuticals on appetite/satiety differed, and subjective and objective results partially agreed; GC/BG may reduce hunger more efficiently than GC.
Implementation of digital storytelling in the classroom by teachers trained in a digital storytelling workshop

This paper presents results of a research study conducted at the University of Houston, in which a group of in-service elementary, middle, and high school teachers learned to use digital storytelling through a series of summer workshops conducted by university faculty and graduate students. The study investigated the teachers' use of digital storytelling in their classrooms, what effects this use had on students, and what problems arose that prevented implementation of digital storytelling in the classroom. The study results suggested that, even though almost all of the teachers' perceptions about using digital stories in the classroom were positive immediately after the workshops, in practice, more than half of the teachers did not continue to use digital storytelling during the implementation period. Teachers who did use digital storytelling reported positive effects on student performance, an increase in 21 st century skills, and increased motivation and engagement levels in their students.
TEMPERATURE CONTROL OF AVOCADOS FOR SEA EXPORT

SUMMARY The condition of sea freighted avocados varies considerably on arrival overseas. Fruit with cold damage as well as soft fruit can be found in the same consignment. This points to a ventilation problem and also an incorrect temperature regime. An experiment confirmed that fruit is temperature sensitive in the climacteric phase and can be stored at relatively low temperatures in the post climacteric phase. A new carton design shows promise in achieving better ventilation. OPSOMMING Avokado's wat per see uitgevoer word, arriveer in varierende kondisie op oorsese markte. Koueskade en sagte vrugte kom dikwels in dieselfde besending voor. Dit dui op 'n ventilasieprobleem sowel as 'n verkeerde temperatuurregime. In 'n proef is bevestig dat vrugte temperatuursensitief is in die klimakteriese fase en veilig teen relatiewe lae temperature in die na-klimakteriese fase opgeberg kan word, 'n Nuwe kartonontwerp toon potensiaal vir beter ventilasie.
Inheriting Multiple and Repeated Parts

The paper describes one aspect of multiple inheritance in the Timor programming language, viz. how "parts" such as a type Radio and a type Cassette Player can be inherited, where appropriate repeatedly, in subtypes such as a Radio Double Cassette Player. Because such types can also be defined via aggregation the paper begins by comparing inheritance with aggregation. It then shows how such cases can be handled first at the type level and then at the implementation level in Timor.
You've got this! The fundamental values of academic integrity

After so many changes in education over the past year, the need to stay grounded in fundamental values is more important than ever. The surge in cognitive offloading tools (i.e. apps and websites that will offer completed academic work), have educators feel they are running a losing race to keep a diverse student body focused on learning content and demonstrating knowledge with integrity. Integrating discussions on the fundamental values of honesty, trust, fairness, respect, responsibility, and courage in classroom supports has allowed the Academic Success Centre and Library Services at Red River College to build academic integrity into their suite of supports. Session presenters will share examples of collaborative sessions that have empowered students to analyze options and make decisions that lead to academic success. Session participants will be asked to reflect on opportunities to integrate the fundamental values into their work. This session will encourage you to use the resources you have to promote academic integrity with confidence.
Inverse Aerodynamic Design Procedure for Propellers Having a Prescribed Chord-Length Distribution

Inverse designmethods are elegant and efficient tools for the design of aerodynamic shapes like airfoils, wings, and propellers. In the case of propeller design, only a few general parameters have to be prescribed and the design procedure returns the propeller geometry in terms of chord-length and blade-angle distributions along the radius. The common design procedures require the prescription of the lift coefficient over the blade radius in order to obtain the unknown chord length. In this paper, a modified design method is presented that allows for designing optimum propellers having a prescribed chord-length distribution. Now the radial distribution of the lift coefficient becomes the unknown, which is determined by the design procedure.
Organizational Climate in Select Public Elementary Schools in Cebu City: A Reality Check

Organizational climate influences to a great extent the performance of teachers in school. It is important to know the shared perceptions and psychological conditions of teachers on workplace activities. This study utilized the descriptive method which is a quantitative research method that attempts to collect quantifiable information and presented facts concerning the degree of occurrence of identified institutional climate in select public elementary schools in Cebu City. Using the Organizational Climate Index (OCI) authored by Hoy, Smith and Sweetland (2002), it was found out that the 86 public elementary school teachers coming from Malubog Integrated School, Adlaon Integrated School, Sibugay Integrated School, Sirao Integrated School, and Alaska Elementary School, have high regard to their schools’ climate in terms of institutional vulnerability, collegial leadership, professional teacher behavior, and achievement press. The researchers concluded that organizational climate of trust which involves great relationships with teachers and staff contributes to the affective commitment of teachers and improves their perception on organizational performance, principals and school head. School heads should be openly communicating with their teachers, subordinates, and other big or small employees like secretaries, messengers, and helpers in schools to ensure that these people will continuously receive feedback and support when needed. It is important that they feel valued. With this positive climate, schools’ work environment will improve and warmth and cooperation will be felt by many.
MOTORCYCLE CRASH: INJURIES PATTERN AND ASSOCIATED FACTORS AMONG PATIENTS TREATED AT MUHIMBILI ORTHOPAEDIC INSTITUTE (MOI).

Road Traffic injuries are of major health problem. In recent years there has been an increase in motorcycling as means of transport in Dar es Salaam and Tanzania as whole. It is believed that motorcycle is also a source of employment and income to young people. This increase in motorcycling has been accompanied by an increase of motorcycle crash injuries. Despite the alarming increase of motorcycle crash injuries, little is known about the pattern of injuries and associated factors of motorcycle crash in the local setting. This study sought to identify the pattern and factors associated with motorcycle crash injuries among the victims treated at Muhimbili Orthopaedic Institute. This was a descriptive cross sectional study involving motorcycle crash injury victims treated at the emergency department of MOI from 15 th March, 2011 to 15 th September, 2011. A structured questionnaire was used to collect the information from the study participants in a face to face interview. Data on demographic factors, injury patterns, use of helmet and license possession were recorded. The injuries were grouped according to anatomical location. Data were entered into the statistical package for social studies (SPSS) program (version 15) for clearing, coding and statistical analysis. P-value of 0.05 was considered significant. In the period of six months a total of 2429 road traffic injury victims were treated at the emergency department of MOI out of who 886(36.5%) were motorcycle crash injury victims. The study included 722 motorcycle crash injury victims, 625 (86.6%) were males and 97 (13.4%) females with a mean age of 33.9 years (SD=13.1), ranging from 13 to 90 years. Majority (65.0%) motorcycle crash injury victims were between the age of 20 and 40 years. The extremity injuries 520 (72.0%) and head injuries 246 (34.1%) were the commonest injuries. The commonest musculoskeletal injury (66.8%) was fracture, with tibia-fibula fracture comprising the largest proportion (30.4%). There were 116 (16.1%) of motorcycle crash injury victims who sustained injury in more than one body regions. The collision between motorcycle and motor vehicle was the most frequently reported
Bidirectional DWDM transmission using a beat-frequency-locking method

In order to achieve the dense-wavelength-division multiplexing (DWDM) in bidirectional optical transmission systems, we present a beat-frequency-locking method to stabilize the relative channel frequency offset between two communicating nodes. Using the proposed method, we demonstrate a bidirectional DWDM transmission having 50-GHz channel spacing in both 2.5- and 10-Gb/s bit rates.
Design of A Microgravity Spray Cooling Experiment

Abstract : An analytical and experimental study was conducted for the application of spray cooling in a micro gravity and high-g environment. Experiments were carried out aboard the NASA KC-135 reduced gravity aircraft, which provided both the microgravity and high-g environments. In reduced gravity, surface tension flow was observed around the spray nozzle, due to unconstrained liquid in the test chamber and flow reversal at the heat source. A transient analytical model was developed to predict the temperature and the spray heat transfer coefficient within the heated region. Comparison of the experimental transient temperature variation with analytical results showed good agreement for low heat input values. The transient analysis also verified that thermal equilibrium within the heated region could be reached during the 20-25s reduced gravity portion of the flight profile.
Possibility of Simulating Natural Circulation in Fast Neutron Reactors Using a Light Water Test Facility

The paper evaluates the possibility of modeling the heat transfer phenomena in a liquid-metal coolant using a light water test facility. It considers the natural circulation of the coolant in the upper plenum of the fast-neutron reactor. The sodium-cooled BN-1200 reactor was selected as the reactor installation to be modeled. The development of novel reactor designs must be based on the results of experimental studies. Some problems of modeling thermohydraulic processes in BN type reactors are studied by using sodium test facilities. Experimental studies of natural convection processes using light water test facilities can be considered as a good alternative to those using sodium test facilities. To validate the model, the similarity theory and the “black box” method were used and their principles and applicability were analyzed. Using the “black box” method makes it possible to avoid detailed modeling of such components as the reactor core and heat exchangers, replacing them by a simplified representation of these components to simulate the integral characteristics of the existing real life equipment. The paper considers the basic criteria which determine the similarity of the thermohydraulic processes under study. The governing criteria of similarity were estimated based on the fundamental differential equations of natural convection heat transfer. Based on these criteria, a set of dimensionless values was obtained which show the correlation between the model parameters and the characteristics of the reactor facility. Besides, generalized relationships were derived which can be used to estimate the scaling factors for calculating the key values of the reactor facility based on the model parameters. These relationships depend on the thermal-physics parameters of the working fluids, the geometrical scale value and the ratio of the thermal power of the model to that of the reactor facility, i.e., model-to-reactor thermal power ratio. The conditions under which it is possible to model sodium coolant by light water with adequate accuracy were analyzed. An example is given of the numerical values of the scaling factors for one of the reference light water test facilities. The paper uses the experience of a number of foreign researchers in this field, in particular, the accepted assumptions which do not result in serious loss in modeling accuracy. According to the available estimates, the assumptions used do not result in considerable losses in accuracy. Thus, the natural circulation of the sodium coolant in the upper plenum of the fast-neutron reactor can be simulated with adequate accuracy by using light water test facilities.
