The maintenance of aircraft presents considerable challenges to the personnel that maintain them. Challenges such as time pressure, system complexity, sparse feedback, cramped workspaces, etc., are being faced by these personnel on a daily basis. Some of these challenges cause aircraft-maintenance-related accidents and serious incidents. However, there is little formal empirical work that describes the influence of aircraft maintenance to aircraft accidents and incidents in Nigeria. This study, therefore, sets out to explore the contributory factors to aircraft-maintenance-related incidents from 2006 to 2019 and accidents from 2009 to 2019 in Nigeria, to achieve a deeper understanding of this safety critical aspect of the aviation industry, create awareness amongst the relevant stakeholders and seek possible mitigating factors. To attain this, a content analysis of accident reports and mandatory occurrence reports, which occurred in Nigeria, was carried out using the Maintenance Factors and Analysis Classification System (MxFACS) and Hieminga’s maintenance incidents taxonomy. An inter-rater concordance value was used to ascertain research accuracy after evaluation of the data output by subject matter experts. The highest occurring maintenance-related incidents and accidents were attributed to “removal/installation”, working practices such as “accumulation of dirt and contamination”, “inspection/testing”, “inadequate oversight from operator and regulator”, “failure to follow procedures” and “incorrect maintenance”. To identify the root cause of these results, maintenance engineers were consulted via a survey to understand the root causes of these contributory factors. The results of the study revealed that the most common maintenance-related accidents and serious incidents in the last decade are “collision with terrain” and “landing gear events’’. The most frequent failures at systems level resulting in accidents are the “engines” and “airframe structure”. The maintenance factors with the highest contribution to these accidents are “operator and regulatory oversight”, “inadequate inspection” and “failure to follow procedures”. The research also highlights that the highest causal and contributory factors to aviation incidents in Nigeria from 2006 to 2019 are “installation/removal issues”, “inspection/testing issues”, “working practices”, “job close up”, “lubrication and servicing”, all of which corresponds to studies by other researchers in other countries.

Conditional Optimization

The paper builds on the ideas of previous research concerning the theoretical explanation of the aircraft operational process with regard to the preferences for maintenance organization by experts and aircraft operators, and describes the designed mathematical models. The problem of conditional extremization is considered. The uncertainty of aircraft technical operation multi-alternativeness is evaluated using the subjective entropy of the aircraft operators’ and experts’ preferences. By applying the subjective entropy extremization principle in view of its maximum, we obtain the conditional optimal distributions of the preferences. The proposed approach allows finding the optimal distribution of the aircraft fleet for the available maintenance alternatives, taking into consideration the restricted possible influences or shadow components of maintenance organizations. The concepts discussed here are important for evaluating the effectiveness of the aviation industry by making allowance for shadow parameters, if needed. The designed model is illustrated with diagrams.

Outbreaks Where Food Workers Have Been Implicated in the Spread of Foodborne Disease. Part 11. Use of Antiseptics and Sanitizers in Community Settings and Issues of Hand Hygiene Compliance in Health Care and Food Industries

Hygiene Compliance

Hand washing with soap is a practice that has long been recognized as a major barrier to the spread of disease in food production, preparation, and service and in health care settings, including hospitals, child care centers, and elder care facilities. Many of these settings present multiple opportunities for spread of pathogens within at-risk populations, and extra vigilance must be applied. Unfortunately, hand hygiene is not always carried out effectively, and both enteric and respiratory diseases are easily spread in these environments. Where water is limited or frequent hand hygiene is required on a daily basis, such as for many patients in hospitals and astronauts in space travel, instant sanitizers or sanitary wipes are thought to be an effective way of preventing contamination and spread of organisms among coworkers and others. Most concerns regarding compliance are associated with the health care field, but the food industry also must be considered. Specific reasons for not washing hands at appropriate times are laziness, time pressure, inadequate facilities and supplies, lack of accountability, and lack of involvement by companies, managers, and workers in supporting proper hand washing. To facilitate improvements in hand hygiene, measurement of compliant and noncompliant actions is necessary before implementing any procedural changes. Training alone is not sufficient for long-lasting improvement. Multiactivity strategies also must include modification of the organization culture to encourage safe hygienic practices, motivation of employees willing to use peer pressure on noncompliant coworkers, a reward and/or penalty system, and an operational design that facilitates regular hand hygiene.

Nontechnical skills are the cognitive and social skills that underpin knowledge and expertise in high-demand workplaces. In the operating room (OR), surgeons with good nontechnical skills can effectively share information about their perceptions of ongoing situations with other team members, elicit critical information from others regarding the task and patient safety, and allow the formation of better shared mental representations about the operation in real time. In rare OR crises, surgeons use their nontechnical skills to delegate tasks and effectively manage challenging operations under time pressure. This review covers approaches in high-risk industry; the development, testing, and usage of the non-technical skills for surgeons (NOTSS) system; and the underpinning theory of nontechnical skills. Tables outline the NOTSS skills taxonomy, behavioral rating tools in surgery, and the skills taxonomy used in the aviation industry. This review contains 3 tables, and 95 references.

Abstract Background Pressure Garment Treatment (PGT) is currently recognized as an effective method to prevent scar formation or treat scar hyperplasia. Research on PGT remains controversial. These controversies indicate that PGT lacks reliable evidence of evidence-based medicine. Different studies on PGT need to be conducted under the same ‘gold standard’ so that different studies can be compared. We consider this ‘gold standard’ to be that the pressure remains stable within a confidence interval during treatment. Methods We calibrated and verified the reference value of the sensor using a cuff of sphygmanometer.A pressure adjustable pressure system was obtained by installing a soft tissue expander on the pressure garment.Local pressure was adjusted by charging and releasing air.Subsequently, the flexible pressure sensor was placed on the upper arm of the healthy volunteers. We validated the compression system on healthy volunteers' forearms and AO standard prostheses (forearms). Results Reference value of the sensor was calibrated on No.1 volunteer. Measuring repeated on No.2 and No. 3. The measurement was very reproducible. The test results in the experimental group showed that the local pressure gradually increased with the increase of the inflation of the airbag. However, the pressure at the opposite position of the forearm changed little. Conclusions Real-time pressure monitoring and pressure adjustment enable the pressure to be maintained at a certain value. Our study provides a new idea for the production of elastic clothing with the function of pressure measurement and pressure regulation, which may promote the accuracy and reliability of PGT.

Reliability Centered Maintenance

Abstract With Lutetium (Lu-177) demand forecasted to increase following the conclusion of clinical trials and product registration in key jurisdictions, manufacturers are seeking to improve their production outputs. Naturally, the question falls to operation and maintenance of these production centers to ensure reliable supply to market. Maintenance in the radiopharmaceutical industry is a complex environment with many competing interactions between radiation safety and Good Manufacturing Practice (GMP) requirements. Since its development by the aviation industry in 1960s, the Reliability Centered Maintenance (RCM) concept has seen adoption by many industries. The International Atomic Energy Agency (IAEA) developed a technical document on RCM applications in nuclear industry in May 2007 while the International Society of Pharmaceutical Engineers (ISPE) refers to the concept in their own baseline guides. Too often, blame for reliability issues falls at the feet of the designers. Careful review of existing strategies against these baseline guidelines often tells a different story. With the view of doubling Lutetium production by the end of 2020 and continued increases over the coming years, there was a push to review the existing maintenance strategies in practice at ANSTO's facilities. This document details the results of that investigation, providing information on the gaps found and the systems implemented to bring maintenance strategies back in alignment with current best practice. It also offers commentary on situations requiring compromises between those best practices defined by IAEA and ISPE.
