Delivering forestry courses online:experiences,lessons learned,and future of forestry online education in the Asia Pacifi c

Innovation in forestry education is needed to address changing contexts of the positionality of forests.This is particularly signifi cant in the Asia–Pacifi c region,where deforestation and degradation are high.However,the accessibility of high-quality forestry education to address changing regional and global contexts is lacking.A series of innovative sustainable forest management(SFM)open education resource(OER)courses were developed and implemented to improve the accessibility of SFM education to enhance teaching quality,curriculum,and research capacity of universities in the Asia-Pacifi c Region.To evaluate the SFM-OER program in terms of student experiences,this study investigated student achievement,perceived success of the pedagogical approach and instructional design,and perceived eff ectiveness of the learning activities in promoting active and transformative learning through the assessment of a 1,191-course feedback survey between 2018 and 2020,including the global pandemic.This study revealed that the program attracted diverse student demographics,including a higher proportion of female students majoring in forestry,ecology,and other environmental studies.Their primary motivation to participate in the courses was to gain international experience,followed by the fl exibility of online learning,mandatory course requirements,and earning course credits.Students were satisfi ed with the Canvas learning management system.Most students spent less than 5 to 10 h of their weekly time in the course and agreed or strongly agreed that the workloads were manageable.Students refl ected positively on various learning activities and assignments,such as watching lecture videos,taking quizzes,reading and summarizing,having discussions,and peer review writing.However,they did not clearly prefer specifi c learning activities,signifying the importance of using diverse learning activities to satisfy diverse individual learning styles in online settings.This analysis contributes to the further development of student-centered pedagogical development for online learning and provides insight into the ways forward for online higher forestry education,while repurposing existing OER courses in a post-Covid-19 era.

Lessons learned from hydrothermal to hot dry rock exploration and production

In this paper,we investigate geothermal exploration and production in 189 hydrothermal projects and 42 hot dry rock projects around the world.The hydrothermal fields for a working hydrothermal system to generate electricity should have the elements of heat source,water-saturated porous or fractured reservoir,caprock,heat transfer pathway,and good heat preservation condition and geothermal power energy intensity of 10-20 MW per km^(2)within at least 5 km^(2)area in tectonically active region.The hot water or steam flow rate in this hydrothermal system is normally larger than 40 L/s with temperature of 150℃or above.The power generated from enhanced geothermal system(EGS)in hot dry rock projects are generally less than 2 MW because the flow rate in most cases is much less than 40 L/s even with the hydraulic fractures using the modern stimulation technology learned from the oil and gas industry.The natural fracture in the subsurface is generally beneficial to the hydraulic fracturing and heat recovery in the hot dry rock.Moreover,the hydraulic fracture parameters,injection rate and well spacing,drilling strategy should be properly designed to avoid the short-circuit between injector and producer and low heat productivity.In the future,CO^(2)enhanced geothermal recovery associated with CO^(2)sequestration in the high temperature oil,gas,and geothermal fields maybe a good choice.On the other hand,both nearreal-time seismic monitoring to limit the pumping rate and the closed-loop of the Eavor-Loop style system without hydraulic fracture can contribute greatly to heat recovery of hot dry rocks and mitigate the risks of the hydraulic fracturing induced earthquake.Furthermore,the hybrid solar and geothermal system performs better than the stand-alone geothermal system.

Retinal ganglion cell neuroprotection by growth factors and exosomes:lessons from mesenchymal stem cells

Retinal ganglions cells （RGCs） are responsible for propagating electrochemical information from the eye to the brain along their axons which make up the optic nerve. The loss of RGCs is characteristic in several conditions such as glaucoma and trau- matic optic neuropathy and leads to visual loss and blindness. While no therapy exists to directly treat RGCs, the use of bone marrow-derived mesenchymal stem cells （BMSCs） has shown promise in eliciting significant RGC neuroprotection.

Effectiveness Study of Lead-in of New Lessons in Classroom Teaching

English teaching is an integral part of education,which shoulders the responsibility of rendering rudimentary knowledge of English to the students,providing the students with the listening,speaking,reading and writing ability,as well as the obligation of carrying out ideological education and cultivating their noble and healthy sentiment.In teaching,the teachers should pay special attention to the students' thirst for English learning and give full play to their initiative,which demands enough lead-in preparation before class.The lead-in of new lessons bears a direct impact on the quality of the classroom teaching.This thesis will make an analysis of this problem in two aspects.

Impact of host genetics on gut microbiome: Take-home lessons from human and mouse studies

The intestinal microbiome has emerged as an important component involved in various diseases.Therefore,the interest in understanding the factors shaping its composition is growing.The gut microbiome,often defined as a complex trait,contains diverse components and its properties are determined by a combination of external and internal effects.Although much effort has been invested so far,it is still difficult to evaluate the extent to which human genetics shape the composition of the gut microbiota.However,in mouse studies,where the environmental factors are better controlled,the effect of the genetic background was significant.The purpose of this paper is to provide a current assessment of the role of human host genetics in shaping the gut microbiome composition.Despite the inconsistency of the reported results,it can be estimated that the genetic factor affects a portion of the microbiome.However,this effect is currently lower than the initial estimates,and it is difficult to separate the genetic influence from the environmental effect.Additionally,despite the differences between the microbial composition of humans and mice,results from mouse models can strengthen our knowledge of host genetics underlying the human gut microbial variation.

Serotonin controls axon and neuronal regeneration in the nervous system:lessons from regenerating animal models

Traumatic brain injury （TBI） is a mechanical injury to brain tissue that leads to an impairment of function and a broad spectrum of symptoms and disabilities; often, it is followed by diffuse axonal injury, which causes denaturation of the white matter and axon retraction, leaving patients with severe brain damage or even in a persistent vegetative state.

Digital Water Developments and Lessons Learned from Automation in the Car and Aircraft Industries

The provision of water and sanitation services is a key challenge worldwide.The size,complexity,and critical nature of the water and wastewater infrastructure providing such services make the planning and management of these systems extremely difficult.Following the digital revolution in many areas of our lives,the water sector has begun to benefit from digital transformation.Effective utilization of remotely sensed weather and soil moisture data for more efficient irrigation(i.e.,for food production),better detection of anomalies and faults in pipe networks using artificial intelligence,the use of nature-inspired optimization to improve the management and planning of systems,and greater use of digital twins and robotics all exhibit great potential to change and improve the ways in which complex water systems are managed.However,there are additional risks associated with these developments,including—but not limited to—cybersecurity,incorrect use,and overconfidence in the capability and accuracy of digital solutions and automation.This paper identifies key advances in digital technology that have found application in the water sector,and applies forensic engineering principles to failures that have been experienced in industries further ahead with automation and digital transformation.By iden-tifying what went wrong with new digital technologies that might have contributed to high-profile acci-dents in the car and aircraft industries(e.g.,Tesla self-driving cars and the Boeing 737 MAX),it is possible to identify similar risks in the water sector,learn from them,and prevent future failures.The key findings show that:①Automation will require“humans in the loop”;②human operators must be fully aware of the technology and trained to use it;③fallback manual intervention should be available in case of tech-nology malfunctioning;④while redundant sensors may be costly,they reduce the risks due to erroneous sensor readings;⑤cybersecurity risks must be considered;and⑥ethics issues have to be considered,given the increasing automation and interconnectedness of water systems.These findings also point to major research areas related to digital transformation in the water sector.

Lessons learned from the TIMI trials in rescue interventions for elderly patients after failed fibrinolytic therapy:look beyond the TIMI flow

In ST-segment elevation myocardial infarction (STEMI), acute reperfusion of the infarct-related artery (IRA)is the main goal in the early minutes after the patient seeks medical attention. Fibrinolytic therapy (FT) and/or primary coronary intervention (PCI) were proven to be effective in opening the IRA.

Implementation of the Active TB Case Finding in Nigeria;Processes, Lessons Learnt and Recommendations

Introduction: Tuberculosis remains a major public health issue in Nigeria with the country ranking seventh among the 30 high TB burden countries. Nigeria is among the three countries that account for half of the 4.3 million “missing” TB cases globally. One untreated TB case is able to infect about 10 - 20 people annually. Hence, it is pertinent that TB is controlled effectively through the use of active case finding strategies to find the missing TB cases. Objective: This article highlights the best practices and key lessons learnt during the implementation of the active house to house TB case finding strategy in Nigeria. Lessons Learnt and Recommendations: Strategic community engagement, massive awareness creation using mass media and local means of communication, mapping of locations where registered TB cases live, to inform home visits for contact tracing and strengthening of laboratory systems, are viable mechanisms to improve TB case finding. Conclusion: Active TB case finding interventions should be implemented in the context of a strengthened diagnostics system, strategic community engagement and media involvement.

Responding to fire in an intensive care unit: Management and lessons learned

Healthcare institutions are vulnerable to disruptionfrom events such as earthquakes, fires, and floods, andthe damage incurred can endanger the lives of patientsin the hospital.[1] In this type of scenario hospital staffhave primary responsibility for the hospitalized patients＇safety, since patients are neither fit to respond to sucha disaster, nor do they know how to respond.[2,3] Thesituation becomes more difficult and challenging if thedisaster occurs in critical care areas such as intensivecare units （ICUs） and operating rooms.

Population-Based Tuberculosis Disease Prevalence Survey in Ghana: The Role and Lessons Learnt from the Laboratory

Background: Bacteriologically-confirmed tuberculosis (TB) cases used in calculating TB prevalence in a country are obtained through laboratory examination of sputum specimens. Objective: This article describes laboratory processing of specimens, results overview, conclusions and key lessons learnt from the perspective of laboratory personnel involved in the conduct of TB disease prevalence survey in Ghana in 2013. Methods: Symptoms screening and Chest X-ray suggestive of TB were used to select participants who produced sputum to confirm TB cases using microscopy, culture and Xpert®MTB/RIF assay (GeneXpert). Results: A total of 15,935 single and paired sputum specimens were received from eligible participants. About half of Ziehl-Nielsen (129/263) and Auramine O (122/246) stained smear positives were scanty positive. Culture positivity rate for Mycobacterium tuberculosis complex was 266/14,994 (1.7%) and 100/15,179 (0.7%) in Mycobacterial Growth Indicator Tube (MGIT) and Lowenstein-Jensen (LJ) media respectively;while non-tuberculous mycobacterium was 294/14,994 (1.96%) and 167/15,179 (1.1%). Total contamination rates in MGIT (5.4%) were higher than in LJ (1.7%). Prevalence of smear positive TB and bacteriologically confirmed TB among adult population (≥15 years) was estimated at 111 (95% CI: 76 - 145) and 356 (95% CI: 288 - 425) per 100,000 population respectively. Conclusions and Lessons Learnt: Direct supervision of specimen collection by well-trained laboratory personnel, timely transportation of specimens from field to laboratory, prompt specimen processing and use of electronic data management systems are essential for a reliable TB disease prevalence survey data. More importantly, strengthening human and logistical capacity of the laboratory must be of utmost priority.

Lessons from International Financial Crisis

Since the advent of the 1990s, international financial crises broke one after an-other with ever greater frequency. They appear in a variety of forms and canbe traced to highly complicated factors. Yet measures could be taken to nip them inthe bud. In the west, stress has been focused on regulating the behavior of finan-

The Effect of Language Proficiency on the Teaching Knowledge Acquisition of English Student Teachers——Comparison of Three Repetitive Lessons

Based on the framework of classroom teaching learning process analysis, this study explores the relationship between language proficiency and the acquisition of teaching knowledge in the sample of three English repetitive lessons in senior high school by two English student teachers. After quantitative and qualitative analysis, it was found that the higher the level of language, the greater the improvement of teaching knowledge;the student with high language level has made rapid progress in teaching design, slow progress in teaching management and student learning, while the progress of the student with low language level is slow in all aspects. This study has important reference value for pre-service foreign language teacher education.

The COVID-19 Pandemic and Higher Education: Common Interdisciplinary Issues and Lessons Learned

Background: Coronavirus-19 (COVID-19) dramatically impacted institutions of higher education. The effect was acute in the practice disciplines such as medicine, medical laboratory science, and nursing. The purpose is to describe how an interdisciplinary team, led by nursing faculty, adapted to the changes driven by COVID-19 and the lessons that were learned for nursing and other disciplines in higher education. Method: The interdisciplinary group created a comprehensive list which captured the impact of COVID-19 on their academic disciplines. Similarities and differences between the disciplines regarding faculty experiences, teaching, and responding to student concerns were discovered. Results: Collective review resulted in the identification of four inclusive thematic categories and several sub-categories. These were: academic considerations (didactic, lab, clinical), perceptions (faculty, student), ethical considerations, and social determinants affecting the learning environment. Lessons Learned: This project utilized an innovative interdisciplinary approach to identify common COVID-19 effects on higher education. Conclusions: Nursing and other health-related disciplines should pursue interdisciplinary collaboration to address common academic issues that arise during the COVID.

Mass Distribution Campaign of Long-Lasting Insecticidal Nets in the Democratic Republic of Congo from 2018 to 2021 in the Context of the Emergence of COVID-19: Results and Lessons Learned

Introduction: The DRC had planned 23 mass distribution campaigns distribution of long-lasting insecticidal nets (LLIN) for the years 2018-2020, the implementation of which spanned from 2018 to July 2021. This article reviews the campaign’s planning process, the results, challenges, and lessons learned. Methods: A descriptive method was used to postpone the planning and implementation process according to the National Malaria Control Program (NMCP) standards adapted to the COVID-19 context. The changes and adaptations implemented as well as the challenges encountered are described. Results: Between January 2018 to June 2021, 23 LLIN mass distribution campaigns were organized in the DRC with the financial support of The Global Fund to Fight against Tuberculosis, AIDS and Malaria (GFTAM) and Against Malaria Foundation (AMF) allowing the distribution of 55,273,473 LLINs to 19,048,372 households at risk of malaria transmission with an average of 2.9 LLINs per household. The enumerated population (111,081,191) exceeded 7% of the micro plans projected population (102,790,391) while the number of households enumerated (19,311,629) was 3% lower compared to the micro planning projection households (19,862,417). Compared to a reported household coverage of 96% of households achieved over the expected households, the independent monitoring carried out revealed 91% of households served in the intervention areas. The main reasons for not reaching households mentioned by the respondents were absence at the time of distribution (26%) followed by the loss of vouchers (16%). Several communication channels were used among which, community workers were the most frequently mentioned (63.1%), followed by radios (18.5%) and churches (12.4%). Conclusion: Good planning, effective coordination of stakeholders, and revision of the implementing campaigns methods following the COVID-19 were factors in the success of this campaign. An effort to respect the schedules for renewing LLINs in households, coupled with good continuous distribution, is necessary to maintain the gains and hope for an impact in terms of morbidity and mortality reduction of malaria.

Historical Examination and Practical Lessons of the Silk Road: A Production-of-Space Perspective

The rise of the ancient Silk Road is a model of cross-nation production of space in early human history. During the Western Han Dynasty, after a passage way to the Western regions was "hollowed out" and secured, commerce and trade along the route boomed, people started to form clusters, and towns and cities were established. Since the late Tang Dynasty, under the combined effects of natural disasters and manmade misfortunes, regions along the Silk Road in Northwest China were severely depopulated, the towns and cities declined, the ecological environment became fragile, and the social space in West China shrank dramatically. The West Development Strategy later launched by the People' s Republic of China had its focus on optimization and reconstruction of domestic social space, whereas the Belt and Road Initiative(referring respectively to "the Silk Road Economic Belt", hereinafter "the Belt", and "the 21 st-Century Maritime Silk Road", " the Road") is rooted in the planning of space for long-term development and production. In building the Belt and Road, we should take the initiative and necessary steps to manage sound top-level designs; further break down the space alienation emanating from the domestic administrative divisions, and stick to the policy of all around opening up; base the endeavor on the new types of urbanization and strengthen social construction to optimize spatial structures; pay attention to the leading role of space consumption by vigorously developing Silk Road tourism; enhance the transportation and communication infrastructure in the node cities to achieve seamless docking and deep-level integration of both social space and natural space along the Belt and Road.

Research on the Design of College English Lessons Based on Hybrid-styled Teaching

At present,our society has gradually developed into an Internet-based society.Driven by the development of the Internet,many areas including education have begun to reform and innovate.Many colleges and universities in China have always adopted the traditional teaching methods,for instance,using a unidirectional teaching method or teaching in a fixed place.In the era of Internet,these methods fail to meet the needs of both parents and students.Subsequently,with the emergence of Internet Plus technology,the limitations that were originally found in the development of English teaching in colleges and universities can be overcome.By combining virtuality and reality,a new mode of simultaneous online and offline teaching has been realized,making English teaching no longer affected by the limitation of space.
