Bacteriological Assessment of Automated Teller and Point of Sales Machine User Interface in Uyo Metropolis, Nigeria

The Automated Teller Machine (ATM) and Point of Sales (POS) machine user interface of different banks, schools, hospitals, restaurants/eateries, shopping malls and petrol/gas stations in Uyo metropolis were bacteriologically assessed in the dry and wet seasons using cultural technique. The result of fomites key pads indicate total heterotrophic bacteria counts (THBC) was in the order: Banks > Hospitals > Schools > Petrol/Gas stations > shopping malls > Restaurants/Eateries in both seasons. There was an increase in the bacterial counts of the fomites from all locations in the wet season compared to the dry season and the difference significant (p = 0.05). The THBC from ATMs in banks, hospitals and schools ranged from 5.6 ± 0.1 to 7.8 ± 0.6 Log₁₀CFU/cm2 and from POS 3.4 ± 0.3 to 5.0 ± 0.2 Log₁₀CFU/cm2) for Petrol/Gas stations, shopping malls and Restaurants/Eateries in the wet season. The dry season revealed THBC range of 4.1± 0.6 to 6.4 ± 0.3 Log₁₀CFU/cm2 for ATMs and 2.6 ± 0.8 to 3.8 ± 0.1 Log₁₀CFU/cm2 for POS. Organisms associated with the fomites were Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis and species of Bacillus, Pseudomonas, Proteus, Streptococcus, Salmonella, Shigella, Micrococcus, Vibrio and Klebsiella. The highest and least frequency of occurrence in the dry season indicated Micrococcus (17.2%) and Vibrio (1.4%) in relation to Staphylococcus aureus (18.2%) and Proteus sp. (2.8%) in the wet season. The Gram-positive organisms exhibited high and low susceptibility to Gentamycin and Augmentin compared to Ofloxacin and Amoxicillin respectively in Gram-negative bacteria. The results indicate ATM and POS machine user interface as possible sources of pathogenic organisms. Therefore, regular cleaning of ATM and POS user interface and public awareness on the need for adequate personal hygienic practice after the use of these machines is recommended to reduce associated risks.

Note to chew on: insect damage to musical instruments.

Insects have a diverse range of ecologies that leaves many pre-adapted to exploiting manufactured products as food sources, including musical instruments. To review what is known and to make recommendations for preventing and managing insect damage to musical instruments, we conducted a systematic search and a narrative review of the area. Of 339 papers, only eight peer-reviewed publications met the inclusion criteria, and all were on xylophagous insects causing damage to wooden instruments. To supplement this material, we report a case of damage to the key pads (composed of felt enclosed in fish buoyancy bladder skin) of a clarinet by carpet beetles (Anthrenus verbasci (Dermestidae)), the first reported case of non-woody damage and the first instance of insect damage rendering an instrument unplayable. To avoid such damage, regular inspection of instruments is recommended, and rapid treatment of any insect infestations in the immediate environment that could extend to affecting stored instruments. Instruments themselves can be extremely expensive, and if insects are still present these should only be treated by an expert; instrument cases can be more easily dealt with by heat treatment (black plastic bag in the sun) or application of a residual insecticide. © 2020 Society of Chemical Industry.

Design, Manufacture, and Experimental Serviceability Validation of ITER Blanket Components

In 2014, the Russian Federation and the ITER International Organization signed two Procurement Arrangements (PAs) for ITER blanket components: 1.6.P1ARF.01 “Blanket First Wall” of February 14, 2014, and 1.6.P3.RF.01 “Blanket Module Connections” of December 19, 2014. The first PA stipulates development, manufacture, testing, and delivery to the ITER site of 179 Enhanced Heat Flux (EHF) First Wall (FW) Panels intended for withstanding the heat flux from the plasma up to 4.7MW/m2. Two Russian institutions, NIIEFA (Efremov Institute) and NIKIET, are responsible for the implementation of this PA. NIIEFA manufactures plasma-facing components (PFCs) of the EHF FW panels and performs the final assembly and testing of the panels, and NIKIET manufactures FW beam structures, load-bearing structures of PFCs, and all elements of the panel attachment system. As for the second PA, NIKIET is the sole official supplier of flexible blanket supports, electrical insulation key pads (EIKPs), and blanket module/vacuum vessel electrical connectors. Joint activities of NIKIET and NIIEFA for implementing PA 1.6.P1ARF.01 are briefly described, and information on implementation of PA 1.6.P3.RF.01 is given. Results of the engineering design and research efforts in the scope of the above PAs in 2015–2016 are reported, and results of developing the technology for manufacturing ITER blanket components are presented.

A Secure Pin Authentication Method against Shoulder Surfing Attacks

Users normally tend to reuse the same personalized identification number (PIN) for multiple applications. Direct PIN entries are highly susceptible to shoulder-surfing attacks as attackers can effectively capture user's PIN entry number with the help of concealed cameras. Indirect PIN entry methods proposed as counter measures are rarely deployed because they demand a heavier cognitive workload for users. To achieve fool-proof security and usability, a practical indirect PIN entry method called SteganoPIN is proposed. The human- machine interface of SteganoPIN comprises two numerical keypads: one shielded or hidden and the other exposed, designed specifically to physically thwart and protect against shoulder-surfing attacks. After locating a long-term PIN in the more usual layout, through the covered permuted keypad, a user generates a one-time password that can safely be entered in plain view of attackers. This enables the user to establish a secure transaction by means of a mobile app to the server by implementing the SteganoPIN method using multi-touch concept that is based on independent variable PIN entry system (Standard PIN, SteganoPIN). The main objective of the project is to create an android application for coping with shoulder-surfing attacks using multi-touch concept in SteganoPIN method. Only after the user PIN entered in the shuffled keypad matches with that of the static keypad, the authentication is then confirmed.Thus, this method allows the user to perform a safe banking transaction through multi-touch SteganoPIN concept. By this method, when the user details are sent to the bank server, a unique MAC id is generated, which should match the user's PIN and MAC id registered in the bank. There are two keypads: static and challenged (or) shuffled key pads; the challenged keypad becomes visible only if the proximity sensor senses the user's cup-shaped hand gesture.

Overview of JSC “NIKIET” activity on ITER Procurement Arrangements

ITER blanket module connectors. Design, analysis and testing for procurement arrangement

A standard ITER Blanket module (BM) is attached to the Vacuum Vessel (VV) with a special system of Blanket Module Connections (BMCs) comprising flexible supports, insulating key pads and electrical straps. BMCs fix the modules relative to the VV and manage the current flow. They accommodate transient, cyclic, thermal and electro-magnetic (EM) loads in a vacuum environment and under neutron radiation. Dynamic, thermal-structural and strength analyses have been performed in support of the BMC design and the results have been experimentally confirmed. The components with uncertain behavior including partially and non-preloaded threads, insulation coating, and electrical contacts were designed by experiments.The effort to develop a reliable and robust design of the BMCs in time for the signature of the Procurement Arrangement on BMCs between ITER Organization and Russian Federation in late 2014 spanned several years. It includes design and analysis as well as experimental activities by the ITER Organization and by JSC “NIKIET” (Russia), which, as an affirmed subcontractor will manufacture and supply BMCs to the ITER site. This paper summarizes the overall effort focusing in particular on the more recent PA supporting activities.

Organophosphorus insecticide, monocrotophos, possesses the propensity to induce insulin resistance in rats on chronic exposure 大鼠长期暴露于有机磷杀虫剂—久效磷后可能诱发胰岛素抵抗

Our earlier studies had shown that monocrotophos (MCP), an organophosphorus insecticide (OPI), has the propensity to augment the secondary complications associated with type-1 diabetes. The present study investigates whether rats exposed for prolonged periods to monocrotophos would develop insulin resistance mediated by alteration in glucose homeostasis. Male rats were administered sublethal doses of monocrotophos daily for 180 days. Interim blood samples were collected to measure alteration in blood glucose and lipid profile. Rats were also subjected to glucose and insulin tolerance test and fasting blood glucose and insulin levels were measured to calculate insulin resistance by HOMA-IR method. After 180 days, the rats were also evaluated for pancreatic histology and activities of hepatic gluconeogenetic enzymes. Monocrotophos elicited a gradual and sustained increase in blood glucose and insulin resistance in rats with concomitant glucose intolerance and reduced insulin sensitivity. MCP exposure was also associated with increase in weights of key white adipose pads, activities of gluconeogenesis enzymes and increase in pancreatic islet diameter, all of which led to hyperglycemia, hyperinsulinemia and dyslipidaemia. Long-term exposure of rats to MCP resulted in glucose intolerance with hyperinsulinemia, a hallmark of insulin resistance. Our data suggest that chronic exposure to low doses of monocrotophos, might lead to development of insulin resistance by altering lipid profile and glucose homeostasis.

Frequency of De Quervain�s tenosynovitis and its association with SMS texting

to assess the frequency of De Quervain's tenosynovitis and its association with SMS texting. a cross-sectional survey was conducted among undergraduate students studying in different physical therapy schools of Karachi belonging to both public and private sectors. Sample size was 300 students which were selected through convenience sampling. Data was collected through self-administered questionnaire and severity of the pain was assessed through Universal Pain Assessment Tool and De Quervain's tenosynovitis was diagnosed through Finkelstein test. Data entry and analysis were done using computer software SPSS version 20. Frequency and percentages were taken for categorical variable. Chi-square was applied to determine association between different variables and Finkelstein test. P value < 0.05 was considered significant. male/female ratio was 1:4. Regarding the use of cell phones, majority 165 (55%) were using regular cell phones, another 89 (30%) were using touch screen and 38 (13%) were using QWERTY key pads. Almost half of the students were frequently using cell phones for texting, out of them 132 (44%) texted less than 50 messages per day. Another 96 (32%) did texting between 50-100 texts. Out of 300 students who filled the questionnaire 125 (42%) students were experiencing pain in the thumb/wrist. Finkelstein test when done on students almost half (n=149) showed positive results. It was noted that as frequency of mobile phone usage increased progressively more and more people showed positive Finkelstein Test (p value 0.000). the result of the study concluded that almost half of the students use their mobile phones for texting more than 50 S.M.S per day and because of their mobile key pads and high speed of texting they experienced pain and weakness over the base of the thumb/wrist which shows the De Quervain's positive in that students and there is a positive association between the thumb pain and frequent text messaging.

Anti-smudge screening apparatus for electronic touch screens

Various applications require surfaces with anti-smudge (finger print resistant) characteristics. Examples include electronic touch screens (for example, mobile phones, tablets, computer screens, key pads, and music players), window glass, and textile clothing. An anti-smudge screening apparatus and methodology have been developed. The anti-smudge properties were examined by wiping two artificially contaminated coatings using oil-impregnated microfiber wiping cloth.

Status of ITER blanket attachment design and related R&D

Main function of the ITER blanket system [1–3] is to shield the vacuum vessel (VV) from nuclear radiation and thermal energy coming from the plasma. Blanket system consists of discrete blanket modules (BM). Each BM is composed of a first wall panel and a shield block (SB). The shield block is attached to the VV by means of four flexible supports and three or four shear keys, through key pads. All listed supports do have parts with ceramic electro-insulating coatings necessary to exclude the largest loops of eddy currents and restrict EM loads. Electrical connection of each SB to the VV is through two elastic electrical straps. Cooling water is supplied to each BM by one coaxial water connector. This paper summarizes the recent evolution of the blanket attachment system toward design solutions compatible with design loads and numbers of load cycles, and providing sufficient reliability and durability. This evolution was done in a frame of pre-defined external interfaces. The ongoing supporting R&D is also briefly described.

Arbitrated Quantum Signature protocol using EPR pairs

Arbitrated signature provides that the signatory signs a message with his private key by quantum cryptography, while the signature receiver verifies the signature with the arbitrator’s assistance. In this work, security analysis was given to the arbitrated quantum signature (AQS) and results showed that the receiver Bob and the attacker can forge the signature. Then this paper gives a new quantum one-time pads encryption method, which is suit for the quantum signature. At last, a new AQS protocol using Einstein-Podoisky-Rosen (EPR) pairs is proposed. By using of quantum key distribution (QKD) and new quantum one-time pads, the new scheme can resist Shor’s attack. The new scheme has following advantages: (1) The scheme reduces the complexity of implementation and provides a higher efficiency in transmission; (2) Compares with some AQS schemes, the scheme can avoid being disavowed by the receiver; (3) Compares with other AQS schemes, the scheme also guarantees the arbitrator cannot forge the signature and it also ensure the receiver and other attacker cannot forge the signature.

Presentation and demonstration of instant student feedback system in improving student participation and learning in pathology in fourth year medical students

Successful learning and teaching of complex pathology concepts and skills involve efficient two way communication between tutor and learner. This is a challenge for large class teaching with limited teacher time and resources. To overcome this challenge, I introduced an electronic student response system in my pathology teaching sessions to fourth year medical students. Following a successful trial in September 2006, the system has been introduced fully into my pathology teaching sessions to monitor and improve student participation, motivation and learning. The system handheld student remote control key pads (www.keepad.com) are integrated into the PowerPoint program by software (www.turningtechnologies.com). Students respond to questions presented in PowerPoint slides including clinical details with either gross or microscopic images asking pathology concepts. Students respond by clicking appropriate buttons on their remotes. The system collects and analyses student responses and presents a graphic display of comprehensive results. The system also provides detailed statistical reports on individual students, groups, whole class and questions. The system has been in use since September 2006 and preliminary data show an overwhelmingly positive student response with a significant improvement in student participation and learning. Major outcomes from the study are:<ul><li>1.Easy recording of student attendance and participation.</li><li>2.Improvements in student attendance, participation and learning.</li><li>3.Instant student assessment with detailed statistical analysis and reporting.</li><li>4.Instant and interactive assessment feedback and learning.</li><li>5.Instant feedback on whole class student learning. Effective assessment tool for the student and instructor.</li><li>6.Student progress monitoring and early intervention.</li></ul> This presentation is an overview of formative assessment, tips and tricks of the student response system and hands on experience using the system effectively to improve student learning.

Clickers are handheld electronic key pads that emit a radio frequency signal and allow students to respond individually to multiple-choice, truefalse, and mathematical questions--either numerical or formulaic. Student responses to questions are collected by a radio frequency receiver using the CPS software, then tallied and reported as a histogram reminiscent of the audience polling used on the TV show Who Wants to Be a Millionaire? The CPS-RF software and associated response clickers are easy to use for the student, and, with just a little patience, the instructor can be up and using clickers in his/her classroom in a matter of a couple hours. A great use of clickers is for data collection. In my general biology for majors class, I have developed a dry genetics lab where students gather data from five family members or friends regarding the presence of such phenotypic characteristics as widow's peak, hitchhiker's thumb, freckles, etc. Students then report their results in class using their clicker. In less than five minutes, I can easily collect this information, then, with the class, discuss the data. It's the best way I've found to show students that dominant alleles are not necessarily the ones which are most frequent in the population. Last year, eInstruction unveiled a much improved version of its CPS software. …

WW9: THE USE OF MULTI-ATTRIBUTE ANALYSIS AND PAIR-WISE COMPARISONS FOR GROUP DECISION-MAKING

OBJECTIVES: Decision-making is a process of assessing alternatives and their attributes versus an objective(s), trading-off various advantages and disadvantages, and ultimately synthesizing the information to culminate at a central point: a decision. The aim of the workshop is to outline a systematic process for group decision-making. A formulary decision incorporating clinical, economic and humanistic data from the perspective of a hospital committee will be used as an illustration. PARTICIPANTS WHO WOULD BENEFIT: Researchers who are involved in creating group decision-analytic models and systems, and stakeholders involved in formulary selection. A key issue in pharmaceutical research is the development and use of applied approaches to help decision-makers synthesize various pieces of information and arrive at a decision. Decision-making is often difficult because trade-offs must be made among competing objectives and priorities. In order to make tradeoffs, we must be able to evaluate and measure each aspect of the decision—some quantitative, some qualitative, some very important, and some not so important. Uncertainties and competing interest groups also add to the complexity of decision-making. The ability to make effective decisions in the face of complexity can be significantly increased by a systematic process incorporating multiple attributes (economics, clinical outcomes, etc.) and pairwise comparisons (A vs. B, B vs. C, A vs. C). The session will describe a systematic approach and provide an interactive illustration for construction of a decision-model based on a process developed by mathematicians at the Wharton School of the University of Pennsylvania. A model will be developed for the formulary selection of cholesterol lowering statins from a hospital P&T perspective, considering economic, clinical and humanistic outcomes, with participation from the audience including handheld key pads for input.

Electronic imaging workstations: ergonomic issues and the user interface.

The electronic imaging workstation serves as the interface between an electronic system and a user. Although the performance aspects of electronic displays are crucial considerations in workstation design, experience suggests that human factors in mechanical operation, software accessibility, and workstation environment are also important. Generally, workstations should have monitors arranged horizontally, and the work environment should be designed to minimize glare from lighting fixtures and to accommodate requirements for low luminance. Devices that control the workstation (eg, key pads, track balls) should be designed so that the user can operate primary and auxiliary controls with efficiency of hand and eye movements. Although many innovations in software (eg, graphical user interfaces) have allowed current workstations to be operated by users who have no knowledge of computer operations, further improvements in interactive software are necessary if such systems are to be accepted by radiologists.

User-Friendly Touch Controls for Home Appliances

Appliances that use more than one cooking mode or have multiple cooking zones or cavities require more controls than their single-mode single-cavity counterparts. The addition of multiple control sets complicates panel appearance and hinders user understanding. A control system is described which can access an unlimited number of functions through a keyboard that uses three dynamically alterable key pads. For ease of use, instructions and prompting are electronically generated and incorporated into the programming sequence.
