IntroductionThailand has not reported any cases of avian influenza since 2008. However, avian influenza viruses circulating in poultry in neighboring countries may have potential for transmission to humans. The aim of this study was to assess risk perceptions of poultry farmers and traders in three border provinces of Thailand adjacent to Laos.Materials and methodsPoultry farmers and traders were interviewed in-person during October–December 2021 by health and livestock officials using a standardized questionnaire to collect demographics, job histories, knowledge, and practices related to avian influenza. Knowledge and practices were scored using 22 questions with a 5-point scale. Exploratory data analysis scores above and below the 25th percentile was used as the cut-off point for perception scores. The cut-off point was used to describe perceptions of respondent characteristics in order to compare differences between groups with more or &lt; 10 years of experience. Age adjusted perceptions of disease risk were analyzed by multivariable logistic regression.ResultsOf the 346 respondents, the median risk perception score was 77.3% (22 questions with a 5-point scale, so the total score was 110). Having more than 10 years of experience in poultry farming was significantly associated with an increased perception of the risk of avian influenza (adjusted odds ratio 3.9, 95% confidence interval 1.1–15.1). Thirty-two percent of participants perceived avian influenza as a risk only during the winter season, and more than one-third of the participants (34.4%) had not received recent information about new viral strains of avian influenza.DiscussionParticipants did not perceive some key information on the risks associated with avian influenza. Regular training on the risks of avian influenza could be provided by national, provincial and/or local officials and they, in turn, could share what they learn with their communities. Participants who had greater experience in poultry farming were associated with greater risk perception. Experienced poultry farmers and traders working on poultry farms can be a part of the community mentorship program to share their experiences and knowledge on avian influenza with new poultry producers to improve their perception of disease risk.

The ethanol fermentation efficiency of sweet sorghum stem juice (SSJ) under a very high gravity (VHG) condition (250 g/L of sugar) was improved by immobilized Saccharomyces cerevisiae SSJKKU01, using a stirred tank bioreactor (STR) coupled with a column bioreactor (CR). Dried rattan pieces (as carriers for cell immobilization) at 50% of the working volume of the CR were suitable for use in a batch ethanol fermentation. The average ethanol concentration (PE) and ethanol productivity (QP) of repeated-batch fermentation in the CR for eight successive cycles were 109.85 g/L and 1.88 g/L⋅h, respectively. Then an STR coupled with a CR was applied for repeated-batch ethanol fermentation in two systems. System I was an STR (1.8 L working volume), and System II was an STR (1 L) coupled with a CR, referred to as a CR-F (0.8 L). Both systems were connected to a new CR, called CR-I, containing sterile dried rattan pieces at 50% of its working volume. Active yeast cells were inoculated only into the STR, and the medium circulation rate between bioreactors was 5.2 mL/min. The results showed that at least eight successive cycles could be operated with an average PE of 108.51 g/L for System I and 109.44 g/L for System II. The average QP and SC values of both systems were also similar, with values of 1.87 to 1.88 g/L⋅h and 93 to 94%, respectively. The morphology of the carriers with and without immobilized cells before and after the fermentation was investigated. The obtained results demonstrated that a repeated-batch fermentation by immobilized cells on rattan pieces, using an STR coupled with a CR, was successfully used to produce high levels of ethanol from SSJ under a VHG condition.
Topology optimization of large ultrasonic tools for uniform vibration using density model
Authors: Wada Yuji , Nakamura Kentaro 
Published: February 2023

Abstract
The uniform vibration of vibrating tools for ultrasonic welding is important for industrial applications but the design requires considerable know-how due to the nature of the wave phenomena. Topology optimization is a structural optimization technique that achieves the desired objective by controlling the material distribution in the design region including voids. In this study, we propose an objective function that maximizes the amplitude of a specific target point in phase with the input. A uniform vibration is obtained by maximizing the point with the smallest amplitude among multiple target points. Optimization is performed using a commonly used density model, resulting in a vibration distribution with an aligned phase on the output surface. In addition, we perform an eigenvalue analysis of the structure by isosurface extraction to study the frequency error and the deterioration in the uniformity of the assumed vibration mode.
Ultrasonic measurement of thickness of carotid arterial wall using its natural longitudinal displacement

Published: February 2023

Abstract
The thickness of the carotid arterial wall obtained from B-mode imaging using ultrasonic diagnostic devices is widely used for the diagnosis of atherosclerosis. However, the measurement interval in the lateral direction of the B-mode image depended on the beam interval (>100 μm). Therefore, the B-mode image is discrete in the lateral direction and cannot reflect changes in local and minute thicknesses. A method for measuring the roughness of the luminal surface of the wall was proposed using the displacement of the carotid arterial wall in the lateral direction during one heartbeat. In this method, the lateral measurement interval is much shorter than the beam interval, enabling a smooth measurement of the luminal surface. By simultaneously applying the method to the lumen-intima and medial-adventitia boundaries of the wall, we propose a novel method to measure the local and minute thicknesses of the carotid arterial wall.

<p>Cybersickness is a drawback of virtual reality (VR), which also affects the cognitive and motor skills of the users. The Simulator Sickness Questionnaire (SSQ), and its variant, the Virtual Reality Sickness Questionnaire (VRSQ) are two tools that measure cybersickness. However, both tools suffer from important limitations, which raises concerns about their suitability. Two versions of the Cybersickness in VR Questionnaire (CSQ-VR), a paper-and-pencil and a 3D –VR version, were developed. Validation and comparison of CSQ-VR against SSQ and VRSQ were performed. Thirty-nine participants were exposed to 3 rides with linear and angular accelerations in VR. Assessments of cognitive and psychomotor skills were performed at baseline and after each ride. The validity of both versions of CSQ_VR was confirmed. Notably, CSQ-VR demonstrated substantially better internal consistency than both SSQ and VRSQ. Also, CSQ-VR scores had significantly better psychometric properties in detecting a temporary decline in performance due to cybersickness. Pupil size was a significant predictor of cybersickness intensity. In conclusion, the CSQ-VR is a valid assessment of cybersickness, with superior psychometric properties to SSQ and VRSQ. The CSQ-VR enables the assessment of cybersickness during VR exposure, and it benefits from examining pupil size, a biomarker of cybersickness. </p>

The present work determined the nutritional quality of Piptocoma discolor and Cratylia argentea as non-timber forest products used in animal feed in the Amazonian foothills in Caquetá province - Colombia, where the grasses B. decumbens and B. humidicola predominate in the pastures.A random selection of 50 farms was made, identifying that in each of them the shrub species Piptocoma discolor, Cratylia argentea and areas of grasslands for grazing where Brachiarias decumbens and B. humidicola predominate. One sample per species was taken from each farm. The samples were subjected to chemical analysis (CP, ADF, NDF, ADL, cellulose, hemicellulose, EE, ash and IVDDM, OMD, TDN, DE, ME). An analysis of variance was performed for each of the variables evaluated using a linear mixed model, considering the species factor as a fixed effect and municipality was considered a random effect. The model assumptions were evaluated by graphical inspection of residual. A multivariate synthesis to see the interrelation between variables and species was performed using a biplot graphic obtained by principal component analysis. C. argentea and P. discolor presented higher CP levels than the grasses in the pastures (17.7; 13.1; and 6.15%, respectively) with good levels of energy intake, confirming that C. argentea and P. discolor are non-timber forest resources with forage potential.

Sampah adalah sisa atau barang buangan yang sudah tidak digunakan dan tidak dpakai lagi oleh pemiliknya. Sampah secara umum dibagi menjadi dua yaitu sampah organik dan an-organik. Kedua sampah ini memiliki manfaat untuk kita, namun juga ada dampaknya untuk lingkungan. Sampah organik adalah limbah yang berasal dari sisa makhluk hidup seperti hewan, manusia, tumbuhan yang mengalami pembusukan atau pelapukan. Sampah ini tergolong sampah yang ramah lingkungan karena dapat di urai oleh bakteri secara alami dan berlangsungnya cepat. Sampah Anorganik adalah sampah yang berasal dari sisa manusia yang sulit untuk di urai oleh bakteri, sehingga membutuhkan waktu yang cukup lama (hinga ratusan tahun) untuk dapat di uraikan. Kegiatan pengabdian masyarakat dilaksanakan di SMP Negeri 4 Bangutapan yang beralamat di Padukuhan Grojogan, Kelurahan Tamanan, Kecamatan Banguntapan, Kabupaten Bantul, Daerah Istimewa Yogyakarta. Adapun pelaksanaan kegiatan dilaksanakan pada bulan November tahun 2022 dengan melibatkan kurang lebih 35 siswa yang merupakan gabungan dari kelas 7 dan 8 SMP Negeri 4 Banguntapan. Anggota yang terdiri dari ketua kelas dan wakil ketua kelas dipilih sebagai peserta pembinaan untuk meminimalisasi jumlah peserta pembinaan yang terlalu banyak. Diharapkan nantinya para anggota pembinaan dapat menerapkan pengetahuan yang diperolehnya kepada warga sekolah yang lainnya. Metode yang digunakan dalam penyampaian materi kegiatan pengabdian masyarakat adalah pendidikan masyarakat. Metode ini dilakukan dengan mengadakan sosialisasi tentang sampah, baik pengertian, jenis, akibat serta cara penanggulangan sampah. Diharapkan dengan memberikan pemahaman dan sosialisasi ini akan membuka wawasan mereka akan pentingnnya menjaga lingkungan dan tidak membuang sampah sembarangan khususnya siswa-siswa dan warga sekolah SMP Negeri 4 Bangutapan.
