Dengan adanya aplikasi ini diharapkan metode promosi dapat berkembang dengan lebih menarik dan tentunya dengan mengandalkan teknologitanpa membutuhkan ruang yang banyak untuk mencapai hasil yang maksimal

Conducting and Mitigating Portable Thermal Imaging Attacks on User Authentication using AI-driven Methods

Thermal cameras have become portable enough to integrate into wearables, such as glasses, and can be used maliciously to infer passwords observing heat traces left on keyboards, keypads and screens. While prior work showed how AI-driven approaches can be used to further enhance the effectiveness of these attacks, we use similar approaches to detect vulnerable interfaces and obfuscate heat traces to defend against thermal attacks. At our Augmented Humans 2023 demo, attendees will have the chance to use a thermal camera to observe thermal traces on a keyboard, and observe how machine learning can both automatically identify keys pressed based and identify, then obfuscate, thermal images of a keyboard to prevent thermal attacks. This demo will provoke thought and discussion about the security risks presented by discrete, wearable thermal cameras and how these risks can be mitigated by both designers and users

Change Policy or Users? Mitigating the Security Risks of Thermal Attacks

Attacks on passwords by thermal cameras are a poignant example of how emerging technologies can pose unforeseen security risks. Despite being easy to perform and effective, thermal attacks are not commonly understood or counteracted, hence a strategy to mitigate this is required. In this paper, we propose an AI-driven strategy to obfuscate vulnerable interfaces in the view of thermal cameras automatically, then discuss the advantages and limitations of attempting to enforce such a system-centred solution as policy, versus instead attempting to shape user behaviour

The mediating role of attention deficit in relationship between insomnia and social cognition tasks among nurses in Saudi Arabia: a cross-sectional study

Purpose: Insomnia-related affective functional disorder may negatively affect social cognition such as empathy, altruism, and attitude toward providing care. No previous studies have ever investigated the mediating role of attention deficit in the relationship between insomnia and social cognition. Methods: A cross-sectional survey was carried out among 664 nurses (M age = 33.03 years; SD ± 6.93 years) from December 2020 to September 2021. They completed the Scale of Attitude towards the Patient (SAtP), the Athens Insomnia Scale (AIS), a single-item numeric rating scale assessing the increasing severity of attention complaints, and questions relating to socio-demographic information. The analysis was carried out by examining the mediating role of attention deficit in the relationship between insomnia and social cognition. Results: The prevalence of insomnia symptoms was high (52% insomnia using the AIS). Insomnia was significantly correlated with attention problems (b = 0.18, standard error (SE) = 0.02, p < 0.001). Attention problems were significantly negatively correlated with nurses' attitudes towards patients (b = −0.56, SE = 0.08, p < 0.001), respect for autonomy (b = −0.18, SE = 0.03, p < 0.001), holism (b = −0.14, SE = 0.03, p < 0.001), empathy (b = −0.15, SE = 0.03, p < 0.001), and altruism (b = −0.10, SE = 0.02, p < 0.001). Attention problems indirectly mediated the effect of insomnia on attitudes toward patients (99% CI = −0.10 [−0.16 to −0.05]), respect for autonomy (99% CI = −0.03 [−0.05 to −0.02]), holism (99% CI = −0.02 [−0.04 to −0.01]) empathy (99% CI = −0.03 [−0.04 to −0.01]), and altruism (99% CI = −0.02 [−0.03 to −0.01]). Conclusion: Nurses with insomnia-related attention problems are likely to have poor explicit social cognition such as attitude toward patients, altruism, empathy, respect for autonomy, and holism

A framework for designing cloud forensic‑enabled services (CFeS)

Cloud computing is used by consumers to access cloud services. Malicious actors exploit vulnerabilities of cloud services to attack consumers. The link between these two assumptions is the cloud service. Although cloud forensics assists in the direction of investigating and solving cloud-based cyber-crimes, in many cases the design and implementation of cloud services falls back. Software designers and engineers should focus their attention on the design and implementation of cloud services that can be investigated in a forensic sound manner. This paper presents a methodology that aims on assisting designers to design cloud forensic-enabled services. The methodology supports the design of cloud services by implementing a number of steps to make the services cloud forensic-enabled. It consists of a set of cloud forensic constraints, a modelling language expressed through a conceptual model and a process based on the concepts identified and presented in the model. The main advantage of the proposed methodology is the correlation of cloud services’ characteristics with the cloud investigation while providing software engineers the ability to design and implement cloud forensic-enabled services via the use of a set of predefined forensic related task

Post-cholecystectomy syndrome: A cohort study from a single private tertiary center

الملخص: أهداف البحث: على الرغم من أن متلازمة ما بعد استئصال المرارة من المضاعفات المعروفة جيدا، الإ ان هناك تقارير قليلة من المملكة العربية السعودية. إن تأثير تكميم المعدة او التصوير الوراثي للقنوات الصفراوية والبنكرياس بالمنظار على الإصابة بمتلازمة ما بعد استئصال المرارة غير معروف. لقد هدفنا الى قياس العوامل المحتملة التي تؤثر على تطور متلازمة ما بعد استئصال المرارة، مثل مدة الأعراض، الأمراض المصاحبة، جراحة السمنة السابقة، ادخال دعامة تصوير القنوات الصفراوية والبنكرياس بالمنظار، التدخل الجراحي، التحول الى الفتح ومعدل المضاعفات. طرق البحث: هذه دراسة جماعية محتملة، دراسة قائمة على الملاحظة أجريت في مركز جامعي خاص واحد. قمنا بتضمين۱٦٧ مريضا خضعوا لعملية جراحية لمرض المرارة في الفترة من أكتوبر ٢٠۱٩ الى يونيو ٢٠٢٠. تم تصنيف المرضى الى مجموعتين وفقآ لحالة متلازمة ما بعد استئصال المرارة الخاصة بهم إيجابية⁄ سلبية النتائج: كان تسعة وثلاثون مريضا إيجابيا لمتلازمة ما بعد استئصال المرارة (٢۳٫۳٪). لم يكن هناك فرق كبير بين المجموعتين فيما يتعلق بالعمر، الجنس، مؤشر كتلة الجسم، التقييم الشخصي لدرجة الصحة العامة للمريض، التدخين، الأمراض المصاحبة مدة الأعراض، جراحة السمنة السابقة، التصوير الوراثي للقنوات الصفراوية بالمنظار، ادخال الدعامة أو بضع العضلة العاصرة. كان التهاب المرارة المزمن هو التشريح المرضي السائد عند٨۳٪ (۱۳٩ ⁄۱٦٧) من المرضى. تشمل الأسباب الأكثر شيوعا لمتلازمة ما بعد استئصال المرارة ضعف الجهاز الصفراوي والإسهال الناتج عن ملح الصفراء والتهاب المعدة ومرض الجزر المعدي المريئي والحصى المحتجزة. كان المرضى المصابون متلازمة ما بعد استئصال المرارة ٧۱٫٨٪(٢٨ ⁄۳٩), بينما كان الباقون يعانون من متلازمة ما بعد استئصال المرارة الاستنتاجات: متلازمة ما بعد استئصال المرارة هي اختلاط مهمل يظهر عند ربع المرضى بشكل رئيسي في السنة الأولى. يمكن ان يساعد وعي الجراح في تشخيص المريض والاختيار قبل الجراحة والتعليم. علاوة على ذلك، يبدو ان تاريخ دعامات تصوير القنوات الصفراوية والبنكرياس بالمنظار أو بضع العضلة العاصرة او تكميم المعدة لا علاقة له بتطور متلازمة ما بعد استئصال المرارة Abstract: Objectives: Although post-cholecystectomy syndrome (PCS) is a well-recognized complication, there are few reports arising from KSA. The effect of sleeve gastrectomy or endoscopic retrograde cholangiopancreatography (ERCP) stenting on the development of PCS is unknown. We aimed to measure the possible factors affecting the development of PCS, such as symptom duration, comorbidities, previous bariatric surgery, ERCP stent insertion, surgical intervention, conversion to open surgery and complication rate. Methods: This was a prospective cohort and observational study conducted at a single, private tertiary center. We included 167 patients who underwent surgery for gallbladder disease between October 2019 and June 2020. The patients were classified into two groups according to their PCS status (PCS+ vs. PCS−). Results: Thirty-nine patients were PCS+ (23.3%). There was no significant difference between the two groups with regards to age, gender, BMI, ASA score, smoking, comorbidities, duration of symptoms, previous bariatric surgery, ERCP, stent insertion or sphincterotomy. Chronic cholecystitis was the predominant histopathology in 83% (139/167) of patients. The most frequent causes of PCS included biliary system dysfunction, bile salt-induced diarrhea, gastritis, gastroesophageal reflux disease, and retained stones. Overall, 71.8% (28/39) of patients had incident PCS; the remaining patients had persistent PCS. Conclusions: PCS is a neglected complication that was observed in 25% of patients mainly in the first year. Surgeon awareness can assist with patient diagnosis, preoperative selection and education. Furthermore, the history of ERCP stenting, sphincterotomy, or sleeve gastrectomy seems to be unrelated to PCS development

On modified Dunkl generalization of Szász operators via q-calculus

Abstract The purpose of this paper is to introduce a modification of q-Dunkl generalization of exponential functions. These types of operators enable better error estimation on the interval [ 1 2 , ∞ ) $[\frac{1}{2},\infty)$ than the classical ones. We obtain some approximation results via a well-known Korovkin-type theorem and a weighted Korovkin-type theorem. Further, we obtain the rate of convergence of the operators for functions belonging to the Lipschitz class
