  • Pig farming, a vital industry, necessitates proactive measures for early disease detection and crush symptom monitoring to ensure optimum pig health and safety. This review explores advanced thermal sensing technologies and computer vision-based thermal imaging techniques employed for pig disease and piglet crush symptom monitoring on pig farms. Infrared thermography (IRT) is a non-invasive and efficient technology for measuring pig body temperature, providing advantages such as non-destructive, long-distance, and high-sensitivity measurements. Unlike traditional methods, IRT offers a quick and labor-saving approach to acquiring physiological data impacted by environmental temperature, crucial for understanding pig body physiology and metabolism. IRT aids in early disease detection, respiratory health monitoring, and evaluating vaccination effectiveness. Challenges include body surface emissivity variations affecting measurement accuracy. Thermal imaging and deep learning algorithms are used for pig behavior recognition, with the dorsal plane effective for stress detection. Remote health monitoring through thermal imaging, deep learning, and wearable devices facilitates non-invasive assessment of pig health, minimizing medication use. Integration of advanced sensors, thermal imaging, and deep learning shows potential for disease detection and improvement in pig farming, but challenges and ethical considerations must be addressed for successful implementation. This review summarizes the state-of-the-art technologies used in the pig farming industry, including computer vision algorithms such as object detection, image segmentation, and deep learning techniques. It also discusses the benefits and limitations of IRT technology, providing an overview of the current research field. This study provides valuable insights for researchers and farmers regarding IRT application in pig production, highlighting notable approaches and the latest research findings in this field.

  • The previous studies focussed on the security problem and the fast re-authentication mechanism during handoffs in a single wireless LAN system. When the multiple wireless LAN systems share their network infrastructure one another, we propose an authentication mechanism allowing the subscriber to Perform the authentication procedure with the authentication server of its own wireless LAN system even in areas of other wireless LAN systems as well as in areas of its own wireless LAN system. In the proposed mechanism, the access point or the authentication server of other wireless LAN systems plays a role of the authentication agent between the subscriber and the authentication server of the subscriber's wireless LAN system. The proposed authentication mechanism is designed on the basis of the 802.1X and EAP-MD5 protocols.

  • The aim of this study is to determine the factors that affect customer satisfaction in the banking sector of Bangladesh because the economic growth and stability of a country depends on the soundness of its banking sector. The study tries to investigate and assess the quality of service on customer satisfaction in the banking sector. As a sample, data were collected from 382 respondents who were customers of 32 selected commercial banks of Bangladesh. A pre-structured questionnaire was used to collect the required data and information. OLS regression model and descriptive statistical tools were used to analyze data. The results of this study reveal that the quality of service (e.g., tangibility, reliability, and empathy) has a statistically significant impact on customer satisfaction. The results also show that there is a positive correlation between the customer satisfaction and service quality dimensions in the banking sector of Bangladesh. The present study finds that in the domestic banking industry the service quality dimensions (i.e., tangibility, reliability, and empathy) have significant positive impact on customer satisfaction. The findings of the present study suggest that Bank Supervisory Authority, Central Bank of Bangladesh, and Bank Management should give special emphasis to ensure maximum satisfaction of banks' customers.

  • Background: Prader-Willi Syndrome (PWS) is a rare genetic disorder. To improve the health deterioration of PWS, investigating optimal treatment options for PWS is required. Thus, we aimed to evaluate the efficacy of pharmacotherapies compared with supportive care or placebos in patients with PWS. Methods: PubMed and EMBASE databases were used to search for randomized controlled trials (RCTs) evaluating the efficacy of pharmacotherapy in PWS patients. Only RCTs that evaluating the efficacy of pharmacotherapy in PWS patients were retrieved. Results: A total of 26 studies were included to evaluate body composition, hormones, glucose levels and hyperphagia behavioral status. Pharmacological treatment group showed a significant decrease of body fat (mean difference (MD): -6.32, 95% confidence interval (CI): -10.58 to -2.06, p=0.004), a significant increase of lean body mass (LBM) (MD: 1.86, 95% CI: 1.43 to 2.30, p<0.00001) and insulin-like growth factor 1 (IGF-1) levels (MD: 241.62, 95% CI: 68.59 to 414.64, p=0.006) compared with the control group. Nevertheless, based on other outcomes evaluated by the current systematic review, pharmacological options showed different efficacy in treating PWS. Conclusion: Pharmacological therapies were effective to decrease significantly in body fat and increase significantly on LBM and IGF-1 levels in patients with PWS. However, still, individualized therapies should be considered in real-world practice in PWS treatment.

  • Phytase increases the availability of phosphate and trace elements by hydrolyzing the phosphomonoester bond in phytate present in animal feed. It is also an important enzyme from an environmental perspective because it not only promotes the growth of livestocks but also prevents phosphorus contamination released into the environment. Here we present a novel phytase derived from Turicimonas muris, TmPhy, which has distinctive structure and properties compared to other previously known phytases. TmPhy gene expressed in the Pichia system was confirmed to be 41 kDa in size and was used in purified form to evaluate optimal conditions for maximum activity. TmPhy has a dual optimum pH at pH3 and pH6.8 and exhibited the highest activity at 70℃. However, the heat tolerance of the wildtype was not satisfactory for feed application. Therefore, random mutation, disulfide bond introduction, and N-terminal mutation were performed to improve the thermostability of the TmPhy. Random mutation resulted in TmPhyM with about 45% improvement in stability at 60℃. Through further improvements, a total of three mutants were screened and their heat tolerance was evaluated. As a result, we obtained TmPhyMD1 with 46.5% residual activity, TmPhyMD2 with 74.1%, and TmPhyMD3 with 66.8% at 80℃ heat treatment without significant loss of or with increased activity.

  • In this paper, we introduce the MC-CDMA (Multi-Carrier CDMA) system with MD (multi-detector). Due to unknown functional form of noise in wireless channel environments, it is not easy to design the detector through estimating the functional form of noise. Instead, we design the MD, which is constructed based on DGT (Data Grouping Technique) and quantiles estimated through RMSA (Robbins-Monro Stochastic Approximation) algorithm.

  • The purpose of this study was to compare the sealing abilities of four endodontic temporary restorative materials using a methylene blue dye penetration test under dynamic loading. Standardized access cavities were prepared in forty-four intact human permanent molar teeth, and the cavities were restored with Caviton, MD-Temp, IRM, or ZOE. After thermocycling, an intermittent load of 98 N at 1 Hz was applied for 1,000 cycles to the long axis of the functional cusp of each of the teeth, which were immersed in a 1% methylene blue solution. The teeth were split in half, and the linear depth of dye penetration was evaluated according to the criteria. The results were analyzed using one-way ANOVA (p = 0.05) and Duncan's multiple range test. The results demonstrated that Caviton and MD-Temp showed significantly lower microleakage than IRM and ZOE. It was concluded that Caviton and MD-Temp exhibited better sealing ability than IRM and ZOE under dynamic loading.
