AbstractAirport security measures continue to be updated with the incorporation of the new body scanners and automatic target recognition software. The purpose of this study was analyze the incidence of: (1) triggering the security alarm; (2) extra security searches; (3) perceived inconvenience; and (4) presence of other surgical hardware in those who underwent total knee arthroplasty (TKA) and passed through airport security. A questionnaire was given to 125 consecutive patients with a TKA. Those who passed through airport security after January 2014 were considered for inclusion. A questionnaire was administered that addressed the number of encounters with airport security, metal detector activation, additional screening procedures, and perceived inconvenience. Out of the 125 patients, 53 met inclusion criteria. Out of the 53 patients, 20 (38%) reported that their prosthesis triggered a metal detector. Out of the 20 patients, 8 (40%) who reported triggering of metal detectors also reported the presence of surgical hardware elsewhere in the body. Eighteen of the 53 patients (34%) believed having a TKA was inconvenient for airplane travel. Compared with the historical cohort, alarms were triggered in 70 of 97 patients (p = 0.0001) and 50 of 97 reported inconvenience when traveling (n = 50 of 97 patients; p = 0.04). The incidences of those who underwent TKA triggering alarms and perceiving inconvenience when passing through airport security have decreased from previously published studies. This is most likely due to the recent updates and modifications to screening. As these security measures are modified and implant designs continue to evolve, this is an area of investigation that should continue.

Introduction: There have been historical reports on the experiences of patients with total hip arthroplasty (THA) passing through standard metal detectors at airports. The purpose of this study was to analyse those who had recently passed through airport security and the incidence of: (i) triggering of the alarm; (ii) extra security searches; and (iii) perceived inconvenience. Methods: A questionnaire was given to 125 patients with a THA during a follow-up appointment. Those who had passed through airport security after January 2014 met inclusion criteria. A survey was administered that addressed the number of encounters with airport security, frequency of metal detector activation, additional screening procedures utilised, whether security officials required prosthesis documentation, and perceived inconvenience. Results: 51 patients met inclusion criteria. 10 patients (20%) reported triggered security scanners. 4 of the 10 patients stated they had surgical hardware elsewhere in the body. 13 of the 51 patients (25%) believed that having their THA increased the inconvenience of traveling. This is different from the historical cohort with standard metal detectors which patients reported a greater incidence of alarm triggering (n = 120 of 143; p = 0.0001) and perceived inconvenience (n = 99 of 143; p = 0.0001). Discussions: The percentage of patients who have THA triggering security alarms has decreased. Furthermore, the number of patients who feel that their prosthesis caused traveling inconvenience has decreased. We feel that this decrease in alarms triggered and improved perceptions about inconvenience are related to the increased usage of new technology.

INTRODUCTION We performed a questionnaire study to establish the frequency and consequences of the detection of orthopaedic implants by airport security and to help us advise patients correctly. All published literature on this subject is based on experimental studies and no ‘real-life’ data are available. PATIENTS AND METHODS A total of 200 patients with a variety of implants were identified. All patients were sent a postal questionnaire enquiring about their experience with airport security since their surgery. RESULTS Of the cohort, 154 (77%) patients responded. About half of the implants (47%) were detected, but the majority of patients (72%) were not significantly inconvenienced. When detected, only 9% of patients were asked for documentary evidence of their implant. We also found that patients with a total knee replacement (TKR) had a greater chance of detection as compared to those with a total hip replacement (THR; 71% versus 31%; P = 0.03). CONCLUSIONS All patients, and in particular those with a TKR, can be re-assured that, although they have a fair chance of detection by airport security, a major disruption to their journey is unlikely. We advise that documentation to prove the presence of an orthopaedic implant should be offered to those who are concerned about the potential for inconvenience, but such documentation is not required routinely.

Introduction Metal detectors have been present in airports and points of departure for some time. With the introduction of heightened security measures in response to fears of an increased threat of terrorism, they may become more prevalent in other public locations. The aim of this study was to ascertain which prosthetic devices activated metal detector devices used for security purposes. Methods A range of prosthetic devices used commonly in orthopaedic and plastic surgery procedures were passed through an arch metal detector at Birmingham Airport in the UK. Additionally, each item was passed under a wand detector. Items tested included expandable breast prostheses, plates used in wrist and hand surgery, screws, K-wires, Autosuture™ ligation clips and staples. Results No prostheses were detected by the arch detector. The expandable implants and wrist plates were the only devices detected by passing the wand directly over them. No device was detected by the wand when it was under cover of the axillary soft tissue. Screws, K-wires, Autosuture™ clips and staples were not detected under any of the study conditions. Conclusions Although unlikely to trigger a detector, it is possible that an expandable breast prosthesis or larger plate may do so. It is therefore best to warn patients of this so they can anticipate detection and further examination.

Background: Due to its association with the risk of falling and consequent injury, the importance of agility is widely recognized, but no study so far has examined the different facets of agility in an untrained/clinical population. The aim of this study was to evaluate the reliability, validity, and correlates of newly developed tests of non-planned agility (NPA) and pre-planned agility (PPA) in an untrained/clinical sample. Methods: The sample comprised 38 participants older than 40 years (22 females, age: 56.1 ± 17.3 years, height: 170.4 ± 10.8 cm, mass: 82.54 ± 14.79 kg) who were involved in a rehabilitation program following total knee arthroplasty and knee arthroscopy. Variables included age, gender, type of surgery, history of fall, anthropometrics/body composition, and newly developed tests of NPA and PPA. Results: The results showed the high inter-testing- (ICC > 0.95, CV < 9%), and intra-testing-reliability (ICC > 0.96, CV < 9) of the newly developed tests. PPA and NPA were found to be valid in differentiation between age groups (>50 yrs. vs. <50 yrs.), and genders, with better performance in younger participants and males. Only NPA differentiated participants according to type of surgery, with better performance in those who had arthroscopic surgery, than those who had total knee arthroplasty. No differences in NPA and PPA were established between groups based on fall-history. In females, the body mass (Pearson’s r = 0.58 and 0.59, p < 0.001) and body fatness (Pearson’s r = 0.64 and 0.66, p < 0.001) were negatively correlated, while the lean body mass (Pearson’s r = 0.70 and 0.68, p < 0.001) was positively correlated with PPA and NPA. The NPA and PPA were highly correlated (Pearson’s r = 0.98, p < 0.001). Conclusions: We found that the proposed tests are reliable when evaluating agility characteristics in an untrained/clinical population after knee arthroplasty/arthroscopy. Further evaluation of the specific validity of the proposed tests in other specific subsamples is warranted.

Purpose Security, safety, environment and health have become an integral part of facility management (FM). Therefore, FM departments within organisations are required to put measures in place to safeguard facility users. This paper thus aims to investigate and compare the safety and security measures that are provided in the student housing of two universities in South Africa. Design/methodology/approach A mixed method approach was adopted; interview was used to collect qualitative data, whereas a questionnaire was used as an instrument to collect quantitative data. Content analysis was used to analyse the qualitative data, whereas both descriptive and inferential statistics were used to analyse the quantitative data. Findings It became evident that university B had a better provision of safety and security measures in the student housing than university A. The study also found that both universities had some lapses in the safety and security measures provided in the student housing. Measures that were lacking in both universities were weapon detector, closed-circuit television (CCTV), water sprinkler system, burglar bars on the doors, lift for disabled students, disabled toilet facility, traffic light, tags for vehicles, first aid box, accident book and medically trained personnel. Research limitations/implications Data were collected from only two universities, making it difficult to generalise the findings of the research. For a broader perspective, a study that expands the number of participating universities is recommended. Practical implications The facility management and safety department in the universities can use the recommendations to improve on the safety and security measures required in the student housing. Moreover, the recommendations can contribute to the development of policy frameworks for student housing safety. Originality/value There is a paucity of studies on student housing safety/security worldwide, and South Africa in particular. With this study, the authors contribute to the body of knowledge in this area of research.

Abstract Precise characterization of concealed person-worn objects will speed up the passenger screening process by reducing the rate of nuisance alarms, while also enhancing the airport security imaging systems. This paper presents an automatic, real-time method for wideband millimeter-wave radar identification of the nominal surface contours of the human body – even with affixed foreign objects or when a segment of the body cross-section is not captured by the radar – without relying on the body's bilateral symmetry. The developed method is verified experimentally when applied to the actual images generated by a laboratory airport scanning prototype developed recently by the US Department of Homeland Security (DHS). Our method uses the noisy collection of radar cross-section reflectivity data to extract the main contours and estimates the nominal body surface cross-sections through fitting a small-term Fourier series of circumferential variation. This is a necessary step for accurate characterizing of concealed terrorist threat objects affixed to the body.

Security Checkpoints

The Transportation Security Administration (TSA) is responsible for protecting the nation's air transportation system. Risk-based security is a paradigm for aligning security resources (i.e., personnel, technology, and time) with security risks. PreCheck is one approach that the TSA uses to implement this strategy. Given that passengers enrolled in PreCheck undergo background checks and fingerprinting, they experience expedited screening at airport security checkpoints, with standard screening lanes dedicated to passengers not enrolled in PreCheck. This difference can favorably impact the TSA’s ability to detect threat items like firearms. This paper uses publicly available data on firearm detection, number of passengers screened, and the fraction of passenger screenings in PreCheck lanes to estimate the number of firearms missed at airport security checkpoints in the United States. To achieve this, it defines risky firearms as firearms carried by passengers not enrolled in PreCheck and assumes that only standard screening lanes are where such firearms are brought to checkpoints. Under this assumption, the number of risky firearms missed in the recent past is estimated, given more current risky firearm detection rates. This analysis suggests that increasing the number of PreCheck passenger screenings may reduce the number of undetected risky firearms passing through security checkpoints.
