Population genetic structure and conservation management of hill pigeons (Columba rupestris) recently endangered in South Korea

Background Hill pigeons (Columba rupestris) are close to local extinction (ca. less than 100 individuals) in South Korea where a variety of conservation management procedures are urgently required. Objective This study was aimed at determining the conservation direction of captive propagation and reintroduction of hill pigeons using genetic information based on mitochondrial DNA. We also evaluated the extent of hybridization between hill pigeons and cohabiting domestic pigeons. Methods We used 51 blood samples of hill pigeons from Goheung (GH), Gurye (GR), and Uiryeong (UR), and domestic pigeons cohabiting with hill pigeon populations. Genetic diversity, pairwise Fst, analysis of molecular variance, and haplotype network analysis were used to examine the genetic structure of hill pigeons. Results Hill pigeons that inhabited South Korea were not genetically distinct from Mongolian and Russian populations and showed relatively low genetic diversity compared with other endangered species in Columbidae. The GR population that exhibited the largest population size showed lower genetic diversity, compared to the other populations, although the pairwise Fst values of the three populations indicated low genetic differentiation. The GH and GR populations were confirmed to lack hybridization, relatively, whereas the UR population was found to exhibit some degrees of hybridization. Conclusion To conserve hill pigeons with low genetic diversity and differentiation in South Korea, the conservation process of captive propagation and reintroduction may require artificial gene flows among genetically verified populations in captivity and wildness. The introduction of foreign individuals from surrounding countries is also considered an alternative strategy for maintaining genetic diversity.

A qualitative study of barriers and facilitators to adequate environmental health conditions and infection control for healthcare workers in Malawi

The burden of healthcare-associated infections (HAIs) is greater in low- and middle-income countries than in high-income countries. Inadequate environmental health (EH) conditions and work systems contribute to HAIs in countries like Malawi. We collected qualitative data from 48 semi-structured interviews with healthcare workers (HCWs) from 45 healthcare facilities (HCFs) across Malawi and conducted a thematic analysis. The facilitators of infection prevention and control (IPC) practices in HCFs included disinfection practices, patient education, and waste management procedures. HCWs reported barriers such as lack of IPC training, bottlenecks in maintenance and repair, hand hygiene infrastructure, water provision, and personal protective equipment. This is one of the most comprehensive assessments to date of IPC practices and environmental conditions in Malawian HCFs in relation to HCWs. A comprehensive understanding of barriers and facilitators to IPC practices will help decision-makers craft better interventions and policies to support HCWs to protect themselves and their patients.

Satisfaction with Detrusor OnabotulinumtoxinA Injections and Conversion to Other Bladder Management in Patients with Chronic Spinal Cord Injury

This study investigated the satisfaction with continued detrusor Botox injections for urinary incontinence and conversion to other surgical procedures and bladder management procedures for neurogenic detrusor overactivity (NDO) in patients with chronic spinal cord injury (SCI). A total of 223 patients with chronic SCI underwent detrusor Botox 200U for urodynamically confirmed NDO and urinary incontinence. After initial detrusor Botox injections, patients opted to either continue detrusor Botox injections every six to nine months and on clean intermittent catheterization (CIC), switch to other bladder management procedures, or receive surgical procedures to improve their urinary incontinence, correct emergent complications, or have better voiding conditions without CIC. Urinary incontinence improvement rates and satisfaction with bladder management were assessed and compared between different subgroups, urodynamic parameters, and bladder management procedures. Finally, a total of 154 male and 69 female patients were included, among whom 56 (25.1%), 81 (36.3%), 51 (22.9%), and 35 (15.7%) showed a marked, moderate, mild, and no reduction in urinary incontinence, respectively. However, only 48.4% of the patients continued detrusor Botox injections over the mean follow-up period of seven years. Patients with cervical or thoracic SCI had fair incontinence improvement rates. The presence of high detrusor pressure and higher-grade bladder outlet resistance also predicted a decrease in incontinence. Although more than 50% of the patients switched to other bladder management procedures or received surgical treatment, 69.1% expressed satisfaction with their current status. This large cohort of patients with chronic SCI who received initial detrusor Botox injections revealed that only 48.4% continued with Botox injections. Those who received surgical procedures due to urological complications or demanded change in bladder management could achieve high satisfaction rates.

The ISO/IEC 29110 Software Lifecycle Standard for Very Small Companies

For many small and start-up software companies, implementing controls and structures to properly manage their software development activity is a major challenge. It is commonly agreed that very small software companies, implementing management procedures, and controls to appropriately administer their software development activity is a significant challenge. To help meet the need for VSE-specific systems and software lifecycle profiles and guidelines, the ISO/IEC jointly published ISO/IEC 29110 “Lifecycle profiles for Very Small Entities” series of standards and guides, with the overall objective being to assist and encourage very small software organization in assessing and improving their software. The purpose of this chapter is to provide a primer on the ISO/IEC 29110 standard focusing on two main process areas of Project Management and Software Implementation.

Human Resource Management in Agile Scrum Processes

The value agile scrum process can generate is not guaranteed simply by mere adoption. Rather the process creates an opportunity for improvement in the development process. Mismanagement of the approach by an organization can reduce the potential added value or in extreme situations have a negative impact. Therefore, appropriate management procedures are necessary to realize the full potential of the agile scrum approach. This chapter focuses on the human resource challenges the agile scrum approach creates for an organization. The dynamic pace, cross-functional composition, and self-directed team approach requires special consideration in the development of most human resource functions. In particular, the authors will review changes to the employee selection, performance management, and learning and career development processes. These changes will better align these functions with the values and principals of the agile scrum approach and help organizations manage this sometimes chaotic approach to innovation without constraining it.

Natural Disasters and Risk Management

In recent years, natural disasters have compelled public authorities, organizations, and citizens to increase their efforts in properly planning and implementing effective risk management procedures. Accordingly, in literature contemporary concepts such as natural disaster risk management and crisis management emerged. Therefore, the chapter aims to shed light on the significance of natural disaster risk management and crisis management in the development of an effective societal system by its transformation and to point out the positive and negative factors influencing these management activities. The authors will firstly give an overview of these two concepts, their elements, and development phases, and afterward, the investigation of possible positive and negative factors of natural disaster risk management will be introduced. The chapter will make a significant contribution to filling the gap in the literature on mitigating the influence of natural disasters and risk management.

Waste Management Practices of Beach Resorts in Biliran Province

A beach resort is a tourist spot, which is excellent for family outings and friends. It is a great place to relax and enjoy. Biliran has known for several different tourist spots, especially the beaches. Beach is one of the famous tourist spots, and those beaches are a haven for scuba divers because of the abundance of marine life. The study’s goal was to find out how beach resorts in Almeria, Biliran, dealt with waste. A descriptive research design was adopted in this study. It's descriptive in the sense that it describes beach resort trash management procedures. Leaves and seaweeds are the most general rubbish found at resorts, according to the findings of the study. According to the results, management should provide more training to employees to improve their knowledge of work and how to become more effective workers in their respective fields.

Non-Invasive Assessment of the Seasonal Stress Response to Veterinary Procedures and Transportation of Zoo-Housed Lesser Anteater (Tamandua tetradactyla)

Management procedures affect behavioural and physiological stress responses of wild mammals under human care. According to the Reactive Scope Model, normal values are presumed to exist within predictive and reactive ranges. First, stress parameters of zoo-housed adult Tamandua tetradactyla were evaluated in winter and summer (29 days each), determining the level of behaviour and/or physiological parameters needed to respond to predictable environmental changes. Secondly, the effects of veterinary procedures and transportation were studied in both seasons. Non-invasive methods were applied, assessing behaviour through videos and adrenocortical activity by faecal glucocorticoid metabolites (FGMs). Lesser anteaters exhibited seasonality (summer > winter) in some behavioural parameters, such as nocturnal activities, as well as in the activity cycle (e.g., acrophase) and FGMs. A veterinary check elicited an increase in total activity (TA), natural behaviours and repetitive locomotion and affected the activity cycle, particularly in summer. Transport produced changes in TA, nocturnal and natural activity and some variables of the activity cycle, mostly during summer. Although the effects of routine management procedures were different from each other and presumably stressful, they elicited changes only at the behavioural level, which was greater during summer. The differences observed according to non-invasive methodologies highlight the importance of a multidisciplinary approach in this context and suggest that it is unlikely that individual welfare was affected.

The Lack of Knowledge on the Microbiome of Golf Turfgrasses Impedes the Development of Successful Microbial Products

Golf courses have a significant environmental impact. High water demands and the intensive use of agricultural chemicals have been a concern for decades and are therefore in the focus of efforts to make golf courses more environmentally sustainable. Products based on modifying or using plant-associated microbiota are one of the fastest-growing sectors in agriculture, but their application on turfgrasses on golf courses is so far negligible. In this review, we summarize the limited knowledge on microbiomes of golf turf ecosystems and show that the lack of holistic studies addressing the structure and function of golf turf microbiomes, including their responses to intense turf management procedures, is currently the main bottleneck for development and improvement of reliable, well-functioning microbial products. We further highlight the endosphere of turfgrasses, which is easily accessible for microbial cultivation through constant mowing, as the most stable and protected micro-environment. Many grass species do possess endophytic bacteria and fungi that have been shown to improve the plants’ resistance towards microbial pathogens and insect pests, and several products using endophyte-enhanced grass varieties are commercially successful. We anticipated that this trend would tee-off on golf courses, too, once a more comprehensive understanding of golf turf microbiomes is available.

Deep Learning-Based Object Detection System for Identifying Weeds Using UAS Imagery

Current methods of broadcast herbicide application cause a negative environmental and economic impact. Computer vision methods, specifically those related to object detection, have been reported to aid in site-specific weed management procedures for targeted herbicide application within a field. However, a major challenge to developing a weed detection system is the requirement for a properly annotated database to differentiate between weeds and crops under field conditions. This research involved creating an annotated database of 374 red, green, and blue (RGB) color images organized into monocot and dicot weed classes. The images were acquired from corn and soybean research plots located in north-central Indiana using an unmanned aerial system (UAS) flown at 30 and 10 m heights above ground level (AGL). A total of 25,560 individual weed instances were manually annotated. The annotated database consisted of four different subsets (Training Image Sets 1–4) to train the You Only Look Once version 3 (YOLOv3) deep learning model for five separate experiments. The best results were observed with Training Image Set 4, consisting of images acquired at 10 m AGL. For monocot and dicot weeds, respectively, an average precision (AP) score of 91.48 % and 86.13% was observed at a 25% IoU threshold (AP @ T = 0.25), as well as 63.37% and 45.13% at a 50% IoU threshold (AP @ T = 0.5). This research has demonstrated a need to develop large, annotated weed databases to evaluate deep learning models for weed identification under field conditions. It also affirms the findings of other limited research studies utilizing object detection for weed identification under field conditions.
