Published: June 2022

The antimicrobial resistance due to Salmonella and other foodborne pathogenic microorganisms, witnessed in recent years, has become a significant health concern. Bacteria use chemical signals to communicate each other and regulate their behavior including virulence. Depending increased antibiotic resistance, new drug development strategies being investigating and the usability of active ingredients of various medicinal and aromatic plants is especially tested as an alternative. The aim of this study was to determine the anti-quorum sensing (QS) activity of cinnamon oil (CO) on pigment production of Chromobacterium violaceum and to evaluate antibacterial activity against multidrug resistant (MDR) S. enterica serotypes. Anti QS activity was tested using biosensor strain and antibacterial activity was determined by microdilution method according to EUCAST standards. CO was found effective on QS mechanisms of Chromobacterium violaceum with pigment inhibition. Nineteen foodborne pathogens isolated from different poultry/cow sourced foods and serotyped as S. enterica serovar Infantis (15), Kentucky (1), Newport (1), Telaviv (1), and Typhimurium (1). S. enterica Infantis strains were found resistant to three or more antibiotics and categorized as MDR. The results concluded that CO has strong antibacterial activity against all S. enterica serotypes with MIC between 0.125 µg ml-1 and 1.0 µg ml-1. This research demonstrates CO is a potential candidate for developing new antimicrobial agents, antiseptic solutions or natural food preservatives against MDR Salmonella isolates also a potential as an anti-QS agent.

Authors: TÜMER Kenan Çağrı , POLAT Eren 
Published: June 2022

A six-day-old calf was presented to the XXX University Veterinary Teaching Hospital with a history of wheezing (noisy respiration), dyspnea that worsens with exercise and drinking. The calf shown upper respiratory tract symptoms including extended head and neck, dilated nostrils, severe inspiratory stridor with characteristic “honking” sound, and exophthalmos. Upon these findings, we suspected upper airway obstruction and decided to perform cervical-thoracal radiography and bronchoscopy to obtain detailed visualization of the upper respiratory tract. On the thorax radiograph, significant tracheal narrowing was visible at the thoracic inlet, and it was beginning at the caudal cervical region (C5) and extending to the cranial thorax (T1). Also, severe dorsoventrally narrowing was displayed approximately 15 cm after entering the trachea using bronchoscopy. The tracheal collapse was diagnosed in this case based on clinical, radiographical, and bronchoscopy findings. It is important to remember that tracheal collapse should be considered in the differential diagnosis in calves that show upper respiratory tract symptoms such as extended head and neck, dilated nostrils, severe inspiratory stridor with characteristic “honking” sound.

Published: June 2022

This study investigated factors determining students' performance in the Introductory Accounting classes. It was carried out using a mixed-method approach. Three research hypotheses based on the results of prior studies were tested using regression analysis. Additionally, a qualitative approach using thematic analysis was used to identify factors influencing students' performance. The study involved 90 students who were selected using the purposive sampling method. Secondary data related to those students were gathered through a documentation procedure, whereas primary data were obtained through interviews and observation involving those sample students. The results of the quantitative analysis showed that motivation had a positive impact on students' performance in Introductory Accounting classes. It was also observed that female students had better performance than male students. However, this study did not find accounting educational background as a significant variable in determining students' performance. For the thematic analysis, the study observed nine factors influencing the students' performance in Introductory Accounting classes. Those factors were related to lecturers, learning method, classroom, family background, references, assignments, tutor, and group study. This study contributes to the upward literature in accounting education. It also provides an insight for the Accounting Study Program in higher education institutions in designing accounting curricula, for lecturers in designing learning processes, and for accounting students in understanding the determinants of their performance.

Abstract
This study evaluated the possibility of using different fillers—cellulose nanocrystal, cellulose microcrystalline, wood flour, soy flour, talc, and calcium carbonate—as partial substitutes in polymeric methylene diphenyl diisocyanate (pMDI) resin. There has been concern recently regarding the use of pMDI resin due to the environmental effect of isocyanate, which is dominantly present in the resin, as well as the cost of the resin. Different fillers were used in this study as substitutes at their allowable substitution percentages. This study focused on the possibility of replacing more pMDI resin with biodegradable filler without compromising the integrity of the resin; the mechanical strength of plywood from both southern yellow pine and oak was evaluated. Fourier-transform infrared spectroscopy, scanning electron microscopy, and thermogravimetric analysis were conducted to study the effect of modification on the bond-line quality of the final product. The effects of different fillers on adhesion properties of the pMDI resin were tested on the plywood according to the American Society for Testing and Materials (ASTM D–906-64) standard. The results showed that shear strength of the modified pMDI resins ranged from 0.3 to 1.083 MPa and 0.35 to 1.178 MPa for oak and pine plywoods, respectively. The modified samples with soy flour showed significant improvement in the shear strength with 261 and 236 percent higher shear strength than the control (pMDI) for samples from hardwood and softwood, respectively. Partial substitution of pMDI resin with soy flour at 30 percent substitution substantially improves the adhesion properties of pMDI resin.

continuous zoom optical system serving for an acousto-optic tunable filter spectral camera has been designed covering a 25–300 mm zooming range. Instead of relying on past experience for roughly determining the initial optical structure, a simulation programming based on Gaussian principle has been composed via MATLAB to accurately calculate the initial designing parameters, which is confirmed to be extremely close to the optimized results using Zemax. The relative design results have been multidimensionally analyzed in detail, which offers fresh thinking for future zoom optical design covering broadband operation wave band.

Authors: Jung Eujene , Ro Young Sun , Ryu Hyun Ho , Shin Sang Do 
Published: June 2022

Introduction
Despite numerous studies on airway management in out-of-hospital cardiac arrest (OHCA) patients, the choice of prehospital airway management technique remains controversial. Our study aimed to investigate the association between prehospital advanced airway management and survival outcomes according to a transport time interval (TTI) using nationwide OHCA registry database in Korea.

Methods
The inclusion criteria were patients with OHCA aged over 18 years old with a presumed cardiac etiology between January 2015 and December 2018. The primary outcome was survival to hospital discharge. The main exposure was the prehospital airway management technique performed by the emergency medical technicians (EMTs), classified as bag-valve mask (BVM), supraglottic airway (SGA), or endotracheal intubation (ETI).We performed multivariable logistic regression analysis and interaction analysis between the type of airway management and TTI for adjusted odds ratios (aORs) and 95% confidence intervals (CIs).

Results
Of a total of 70,530 eligible OHCA patients, 26,547 (37.6%), 38,391 (54.4%), and 5,592 (7.9%) were managed with BVM, SGA, ETI, respectively. Patients in the SGA and ETI groups had a higher odds of survival to discharge than BVM groups (aOR, 1.11 (1.05–1.16) and 1.13 (1.05–1.23)). And the rates of survival to discharge with SGA and ETI were significantly higher in groups with TTI more than 8 minutes (1.17 (1.08–1.27) and 1.38 (1.20–1.59)).

Conclusion
The survival to discharge was significantly higher among patients who received ETI and SGA than in those who received BVM. The transport time interval influenced the effect of prehospital airway management on the clinical outcomes after OHCA.

Authors: Nelmi Wahyuni  , Widi Prasetia  
Published: June 2022

Periapical lesions develop from non-vital teeth. In teeth with non-hermetic root canal filling, the presence of microleakage bacteria will invade the root canal and reach the periradicular area and cause inflammation so that it develops into periapical lesions as a form of failure of root canal treatment. Periapical lesions should be treated with a non-surgical endodontic procedure with a fair success rate. The purpose of this case report was to evaluate conventional endodontics as non-surgical management of teeth with a periapical lesion in previously treated teeth.
Case: A 25-year-old female patient came to a private practice with a complaint of cavity in her lower left molar. One month ago, she had a throbbing tooth pain for which she took analgesic medication. The tooth was treated by root canal treatment about 6 years ago. The patient had no history of systemic disease.
Case Management: Occlusal Adjustment, non-vital root canal treatment, the core build-up (fibre reinforced composite) and full coverage direct composite restoration.
Conclusion: Adequate root canal treatment affects the success of endodontic treatment, in this case, there was very good progress in healing of the periapical lesion.
Periapical lesions develop from non-vital teeth. In teeth with non-hermetic root canal filling, the presence of microleakage bacteria will invade the root canal and reach the periradicular area and cause inflammation so that it develops into periapical lesions as a form of failure of root canal treatment. Periapical tissue develops in response to microbial assumption and their by-products that infiltrate the periradicular tissues and activate the host's immune reaction. A dynamic encounter between the host's immune response and microbial infective factors at the interface of the periodontal membrane and infected pulpal tissue results in various periapical lesions.[1,2,3]
Periapical lesions should be treated with a non-surgical endodontic procedure with a fair success rate. Microbial elimination or minimization from the pulp system using efficient chemo mechanical preparation can lead to a successful treatment.[1,4,5] The aim of this case report is to evaluate conventional endodontics as non-surgical management of teeth with a periapical lesion.

Published: June 2022

Abstract
For the past three decades, AA7075 based metal matrix composite materials showed more attraction due to their enhanced mechanical and fatigue properties. The mechanical and fatigue behaviour of nano composites needs more investigation for their applications. In the present study, stir casting route based AA7075 reinforced with nano – sized, Al2O3 particles (average size 35 nm). The evaluation of mechanical and fatigue properties in the nano cast composites and matrix were carried out at room temperature (RT). The composites and base metalwere subjected to high and low cycle fatigue. Scanning Electron Microscope was used to estimate fatigue behaviour of nano composites samples. The mechanical and fatigue properties was enhanced by the nano Al2O3, when compared to the matrix. The microsite evaluation showed uniform distribution of Al2O3 particles into the matrix and few porosity was recorded. The improvement of the properties above is attributed to the grain refinement and to the distribution of the Al2O3.
