Introduction: Bite marks are unique to each, differing between one person and another. Several methods to analyse bite mark have been developed during certain periods. However, a standard method to analyse and evaluate the bite mark anatomic variations has not been developed. The objective of this research was to identify the differences of the inter-canine distance on dental cast model, wax impression tracing, radiograph of dental impression tracing, and dental cast tracing methods of the human bite mark. Methods: The subject of the research was as much as 30 consecutive dental cast model, wax impression tracing, radiograph of dental impression tracing, and dental cast tracing for both maxilla and mandible. Measurements performed on each group were conducted in the inter-canine areas using a Vernier calliper. The gold standard that used as a comparator was a dental cast model group on both maxilla and mandible. Comparison of the measurement results was carried out and analysed using a one-way ANOVA test and Tukey LSD test. Results: The average sizes of maxilla and mandible were 37.93 mm and 31.70 mm for dental cast model; 37.93 mm and 32.83 for wax impression tracing; 38.20 mm and 31.70 mm for radiograph dental impression tracing; and 36.65 mm and 30.76 mm of dental cast tracing. The significance value of the maxilla was p = 0.008 (p < 0.05), and the significance value of mandible was p = 0.000 (p < 0.05). Conclusion: The inter-canine distance of radiograph tracing group is found to be most similar with dental cast group as gold standard both in the maxilla and the mandible. Keywords: Bite mark, dental cast, wax impression, radiograph, tracing

<p><strong><em>Abstract:</em></strong><em>. </em><em>Based on the syllabus of thermodynamics course in several Engineering Study Programs at Politeknik Negeri</em><em> </em><em>Bandung, it shows a very high need for Applied Physics on the subject of Thermodynamics as a prerequisite course. To be able to understand the concept of thermodynamics through laboratory activities, in this research the design and optimization of the Charles Gay-Lussac’s Law device was carried out, the measurement results were confirmed by calculation data using literature. Charles's law states that at fixed pressure, the volume of ideal gas with a certain mass is directly proportional to its temperature and Gay-Lussac's Law states that if the gas in a closed container is kept constant then the gas pressure is directly proportional to its absolute temperature.</em><em> The results of the design of the Charles’s law experiment device, on P = 925 mbar and T = 298 K, obtained the average pressure of the trial results is 1043 mbar. The test results from the setting of the device show the average coefficient of determination (R<sup>2</sup>) = 0.9969, meaning that the effect of temperature is strong on changes in volume at a fixed pressure. In the design of the Gay-Lussac’s law experiment, at 925 mbar, T = 297.6 K and the volume of air in the flask was 0.578 x 10<sup>-3</sup> m<sup>3</sup>, the number of moles of the average test shows a relatively consistent value of 1.51 mmol that is in the order of 10<sup>-2</sup> mol. The test results show the value of R<sup>2</sup> = 0.9822, meaning that the effect of temperature is strong on changes in pressure at a fixed volume.</em><em></em></p><p class="AbstrakIndonesia"><strong>Abstrak:</strong> Berdasarkan kajian silabus mata kuliah termodinamika pada beberapa Program Studi Teknik di Politeknik Negeri Bandung menunjukkan kebutuhan yang sangat tinggi terhadap mata kuliah Fisika Terapan pokok bahasan Termodinamika sebagai mata kuliah prasyarat.

Perimeter control is used to regulate transfer flows between urban regions. The greedy control (GC) method takes either the minimum or the maximum for the control inputs. Although it has the advantage of simplicity for real-time feasibility, a few existing studies have shown that it can sometimes have negative impacts because of unnecessary transfer flow restrictions. To reduce unnecessary restrictions, this study provides a method that gives flexibility to ease the strict conditions of the conventional GC. First, we propose a modification as a way of granting exceptions to the flow restriction under specific conditions. Second, we develop an algorithm to determine the threshold dynamically for accepting the exception, by comparing the possible outflow loss of the subject region and the possible outflow gain of its neighboring regions. The test results show that this flexible greedy control can handle the balance between the transfer demands and the greed of regions for securing the supply level, while increasing the performance in both vehicle hours traveled and trip completion.

Objective: To determine the accuracy of CT chest in diagnosis of COVID-19 taking RT-PCR-testing as gold standard. Materials and Methods: A total of 150 patients of suspicion of COVID-19 who were referred for CT Chest in Radiology Department of Nishtar Medical University Multan from June-2020 to May-2021 were included. In all patients, two RT-PCR test results were obtained with 7 days of admission in hospital. Presence of any of these positive was labelled as COVID-19 infection. CT chest was performed in all patients within 2 days of admission in hospital using 128 slices CT scan machine. The diagnosis of COVID-19 infection was made according to the recommendations by Radiological Society of North America (RSNA) protocol. Results: Mean age was 51.3±14.7 years. 78 (52%) patients were male and 72 (48%) patients were female. RTPCR test was positive in 89 (59.3%) patients. While the CT chest findings were suggestive of COVID-19 infection in 130 (86.7%) patients. The sensitivity of CT chest was 95.5%, specificity 26.2%, PPV wad 65.4% and NPV was 80.0%. Conclusion: CT chest has a very good sensitivity for detection of COVID-19, it can be used as a rapid diagnostic tool especially in areas of pandemic. However, the specificity of CT chest is low, that can limit its use in low COVID-19 affected areas.

The heart is one of the most important organs in the human body. One way to know heart health is to measure the number of heart beats per minute and body temperature also shows health, many heart rate and body temperature devices but can only be accessed offline. This research aims to design a heart rate detector and human body temperature that the measurement results can be accessed via web pages anywhere and anytime. This device can be used by many users by entering different ID numbers. The design consists of input blocks: pulse sensor, DS18B20 sensor and 3x4 keypad button. Process blocks: Arduino Mega 2560 Microcontroller, Ethernet Shield, router and USB modem. And output block: 16x2 LCD and mobile phone or PC to access web page. Based on the test results, this tool successfully measures the heart rate with an average error percentage of 2.702 % when compared with the oxymeter tool.

The standardised testing of school children has been the subject of significant news media attention in recent years in many developed countries around the world. This article examines the reporting of annual National Assessment Program Literacy and Numeracy (NAPLAN) tests in three major Australian newspapers, with a particular focus on the portrayal of school teachers in the coverage. Overall, teachers were presented as strongly opposed to NAPLAN and the publication of test results, yet the newspapers themselves supported the tests as an important accountability measure. Teachers were depicted as trying to influence the testing system through teaching to the test and cheating. They were presented as generally inadequate as teachers, and were blamed for perceived failings in the educational system. These findings point to implications for teacher recruitment and retention, and for journalism education and training.

Background/aim: In the field of contemporary head and neck reconstructive surgery, free vascularized tissue transfer is becoming a gold standard. The aim of this study was to review our clinical results and experience, with use of free microvascular flaps and compare them with the recently published patient series. Methods. During the period from 2001 to 2005, 37 patients underwent microsurgical reconstruction after the tumor ablation in the region of head and neck. Flap viability was monitored intraoperatively with the Ackland test and postoperatively by the clinical observation and mini-Doppler test. Results. The overall success rate was 83.8%. The complications that appeared were: one complete flap necrosis due to venous thrombosis, and five late flap ischemic necroses, in the period from the 10th to 14th postoperative day. Conclusion. Free flap reconstruction of the head and neck is a surgical technique that provides the reconstruction of complex and extensive defects, that could not be performed by using local or regional flaps.
