The past two decades have uncovered the beneficial relation of physical activity and other health behaviors on brain and cognition, with the majority of data emerging from older adult populations. More recently, a similar research thread has emerged in school-aged children, which offers insight into the relation of physical activity to scholastic performance, providing a real-world application of the benefits observed in the laboratory. Technological advances have similarly furthered our understanding of physical activity effects on cognitive and brain health. Given this emerging body of work, this manuscript reviews the basic findings within the field, but more importantly suggests triggers or signals from the emerging literature that will shape the field in the near future. The overall goal of this body of research is to increase cognitive and brain health to promote effective functioning of individuals across the lifespan.

Sootblowing technology used in recovery boilers originated from that used in coal-fired boilers. It started with manual cleaning with hand lancing and hand blowing, and evolved slowly into online sootblowing using retractable sootblowers. Since 1991, intensive research and development has focused on sootblowing jet fundamentals and deposit removal in recovery boilers. The results have provided much insight into sootblower jet hydrodynamics, how a sootblower jet interacts with tubes and deposits, and factors influencing its deposit removal efficiency, and have led to two important innovations: fully-expanded sootblower nozzles that are used in virtually all recovery boilers today, and the low pressure sootblowing technology that has been implemented in several new recovery boilers. The availability of powerful computing systems, superfast microprocessors and data acquisition systems, and versatile computational fluid dynamics (CFD) modeling capability in the past two decades has also contributed greatly to the advancement of sootblowing technology. High quality infrared inspection cameras have enabled mills to inspect the deposit buildup conditions in the boiler during operation, and helped identify problems with sootblower lance swinging and superheater platens and boiler bank tube vibrations. As the recovery boiler firing capacity and steam parameters have increased markedly in recent years, sootblowers have become larger and longer, and this can present a challenge in terms of both sootblower design and operation.

Reports on the news about nature or man-made catastrophes are not uncommon. We hear constantly that a human catastrophe has taken place somewhere in the world. In those cases where the infrastructure could possibly be destroyed, it becomes clear that a rescue mission is difficult to achieve. We need special rescue teams, who despite the difficult rescue mission, save lives and reduce suffering.The special organizations involved in catastrophes are called humanitarian organizations. In addition, the specific skills and abilities that these organizations have should be mainly in logistics.In this paper, the author goes into more details about humanitarian logistics and shows its importance in disaster areas. Unfortunately, these humanitarian organizations have many weaknesses and challenges. As a result, these organizations are not well developed, despite their importance. In contrast, the commercial logistics companies, which are well developed, have much strength in management, information technologies, etc.This research defines humanitarian logistics and describes its weaknesses and limitations. Furthermore, it deals with the specifics of humanitarian organizations. The special features of these organizations are their rescue missions, especially in destroyed infrastructure areas. This research demonstrates the various similarities between commercial and humanitarian logistics and points to the potential of knowledge and experience transfer from commercial logistics to humanitarian logistics.This research compares humanitarian logistics with commercial logistics. In doing so, the author tries to gain a deeper insight into the potential of transferring know-how and experience from retail logistics to humanitarian logistics in order to strengthen humanitarian logistics.The research of logistics is a very dynamic world in which humanitarian logistics is becoming increasingly important both in research and in practice. In particular, the demands on logistics in general and on humanitarian logistics, in particular, will increase significantly in the near future because it is estimated that the number and impact of both natural and human disasters is increasing (Kumar et al., 2012).Murphy (2015) analyzed the past data of catastrophes and derived a forecast for the future frequency of disasters and their impact: “Because of the increasing frequency (and severity) of disasters over the past 50 years, humanitarian logistics is likely to be an important topic into the foreseeable future”.

Physical inactivity has been shown to increase the risk for several chronic diseases across the lifespan. However, the impact of physical activity and aerobic fitness on childhood cognitive and brain health has only recently gained attention. The purposes of this article are to: 1) highlight the recent emphasis for increasing physical activity and aerobic fitness in children’s lives for cognitive and brain health; 2) present aspects of brain development and cognitive function that are susceptible to physical activity intervention; 3) review neuroimaging studies examining the cross-sectional and experimental relationships between aerobic fitness and executive control function; and 4) make recommendations for future research. Given that the human brain is not fully developed until the third decade of life, preadolescence is characterized by changes in brain structure and function underlying aspects of cognition including executive control and relational memory. Achieving adequate physical activity and maintaining aerobic fitness in childhood may be a critical guideline to follow for physical as well as cognitive and brain health.

Smart pen technology has evolved over the past decade with new features such as Bluetooth connectivity, bolus dose calculators, and integration with mobile apps and continuous glucose monitors. While similar in appearance to a traditional insulin pen, smart pens have the ability to record and store data of insulin injections. These devices have the potential to transform diabetes management for clinicians, and patients with type 1 and type 2 diabetes on insulin therapy by improving adherence, glycemic control, and addressing barriers to diabetes management. Smart pens can also highlight the relationship between insulin, food, and physical activity, and provide insight into optimizing insulin regimens. Education of clinicians and patients, and more clinical studies showing the benefits of smart pens and cost-effectiveness, are needed.

This manuscript, which arose from the inaugural Tom Rowland Lecture Series at the 2016 North American Society for Pediatric Exercise Medicine conference, provides a brief descriptive review of what is known (i.e., the state of the science) regarding the relation of childhood physical activity (PA) and cardiorespiratory fitness (CRF) to brain health, cognition, and academic outcomes. Gaps in the knowledgebase are identified, including characteristics of the PA stimulus that promotes changes in brain and cognition, whether critical periods in development exist in which PA/CRF may have a disproportionately large influence, the understanding of individual difference factors, and the influence upon learning. Lastly, several possible directions for future research are proposed. Although the field of childhood PA, CRF, brain, and cognition is rapidly expanding, there is considerable room for future growth. This manuscript may be helpful in shaping that future growth, with the goal of improving lifelong health and effective functioning.

AbstractThis paper reviews empirical research exploring primary/elementary school aged children movement competence assessment over the twenty year period, 1997-2017. The review occurs within the context of a recent global report into children’s physical activity, sedentary behaviour, and movement competence revealing many children reach adolescence with poor movement competence attainment. A qualitative, narrative review of this extant literature on children’s movement competence research was undertaken. Themes were interpretatively drawn from an examination of the summaries. The number of different test types and protocols used in this field of research complicates the comparison of findings and outcomes of the research. The most common reported upon factor in movement competence was gender. Evidence of an association between movement competence, physical activity intensity and habitual physical activity was found. The sameness of the findings over the past twenty years leads us to suggest that new and novel research methods would enhance understanding in this area, particularly with regards to programs that are successful in moving more children towards movement competence benchmarks.

Unlike other global natural-, industrial- and intentional disasters of the past, if any impact was felt in South Africa, it was due to uncertainty within the tourism sector and guests being hesitant to travel. COVID-19 has had an economic and catastrophic impact on hospitality businesses, and particularly in the South African hospitality industry, resulting in changes in how the industry operates. Therefore, the purpose of this study was to investigate whether reactions to lockdown and the subsequent collapse of domestic and international travel should have been approached differently, and what hospitality leaders anticipate for the near future of the industry. The significance of the study is to highlight that better planning should have occurred to have reduced the negative impact of the disaster. Returned emailed qualitative questionnaires from hospitality industry partners provided insight into the weeks before lockdown. The results indicate that there was a contingency plan in place within the larger hospitality operations but the timing was too short to allow adequate implementation. Smaller operations have been the most affected, with losses of contracts, employee incomes, and positions. The economic effects on the operations will require months to resolve, with many smaller operators not being able to survive.

ObjectiveMany young people do not practise enough physical activity (PA) to benefit their health. The three-cohort study aimed to investigate the prevalence of PA and understand the trends between 2002 and 2010, using a representative sample of Portuguese adolescents.Design, setting and participantsThe participants were 8483 adolescents (4067 boys, 4416 girls) who participated in the Health Behaviour in School-aged Children Portuguese survey in 2002, 2006 and 2010.Design, setting and participantsA questionnaire was used to collect data of PA. Analyses were run separately for boys and girls.ResultsBoys aged 15–17 reported practising 3.5±1.9 times a week in 2002, 3.9±1.9 times a week in 2006 and 3.8±1.9 times a week in 2010, with a significant increase from 2002 to 2006/2010 (p<0.05). PA practice during the past 7 days decreased from 4.2±2.1 to 3.9+1.9 between 2002 and 2006 (p<0.001) and also decreased from 4.4±2.1 to 3.8±1.9 between 2006 and 2010 (p<0.001). Among girls, PA practices during the past 7 days declined significantly from 3.5±1.9 to 2.7±1.7 between 2002 and 2006 (p<0.001), and from 3.3±1.9 to 2.9±1.7 between 2006 and 2010 (p<0.001).ConclusionsThe study points to age as a factor related to diminished PA participation. The study also revealed that the prevalence of PA has decreased over the years for the same age groups.

Summary Study aim: Over the past decade there have been numerous efforts to identify how many steps/day children should accumulate. Recommendations range from 10,000 to 16,500 steps/day. The purpose of this article was to examine the percentage of elementary school aged children meeting nine different sets of steps/day recommendations. Material and methods: 786 Southwestern US children (410 girls, BMI 19.3±4.2) wore the Yamax Digiwalker SW-200 pedometer and recorded their steps/day for 7 consecutive days. Mean steps/day was calculated and the percent-age of students meeting each of the various steps/day recommendations was determined. Results: Children averaged 11,113±3,666 steps/day. Sixty-one percent of all children met a minimum of 10,000 steps/day. Thirty-six percent met the most widely used recommendation of 11,000 and 13,000 steps/day for boys and girls, respectively. Using BMI referenced recommendations, between 10-52% of children met various guidelines. Conclusions: Southwestern US children in the current sample are not getting enough daily activity to meet the ma-jority of step recommendations. Findings suggest that less than 33% of children are active for 60 minutes of physical activity (inferred from one of the guidelines) a day and only 36% would qualify for the Presidential Active Life-styles Award. Additional school and home-based physical activity programming is clearly needed.

Notions of banking and finance have gradually changed over the past decade at the personal level, with the increasing spread of personal computers, personal finance software, and online services. Technological advances however have been hindered by administrative inertia in most traditional banks and the lack of accepted national and international policies for the management of digital cash. The radical efficiencies of virtual banking, in the absence of paper records, files, and documents, mean that financial services at both the institutional and personal level will change remarkably in the very near future.
