Published: May 2021

ABSTRACT

Objectives
To discern the effects of computer-aided design (CAD)/computer-aided manufactured (CAM) customized appliances and piezocision on orthodontic treatment (OT).

Materials and Methods
The study combined findings from two previously published randomized controlled trials: (1) standard OT vs piezocision-assisted standard OT, and (2) CAD/CAM OT vs piezocision-assisted CAD/CAM OT. Piezocision is a minimally invasive corticotomy surgical procedure used to accelerate orthodontic treatment and CAD/CAM refers to CAD/CAM customized brackets and archwires. The outcomes were the overall treatment time, and the durations of the alignment phase and fine-tuning phase. Clinical and radiological features also were evaluated.

Results
The combined study included 48 patients with similar baseline characteristics. Compared to the standard treatment, CAD/CAM technology alone significantly decreased the overall median OT time from 543 to 394 days (P &lt; .001) and from 543 to 254 days (P &lt; .0001) when combined with piezocision. Although piezocision significantly reduced the duration of the alignment phase in the mandible and maxilla, CAD/CAM technology considerably shortened the fine-tuning phase. All periodontal and radiographic parameters remained stable from the start to the end of treatment in all groups.

Conclusions
CAD/CAM technology combined with piezocision accelerates the entire OT process, during the alignment phase for piezocision and during the fine-tuning phase for CAD/CAM, with a global reduction of the overall treatment time of more than 50%.

Published: May 2021

Penelitian ini menunjukkan bagaimana penerapan metode guided inquiry untuk meningkatakan keterampilan proses sains (KPS) siswa Sma?”. Namun karena KPS dalam penelitian ini di batasi pada keterampilan berkomunikasi, keterampilan mengajukan pertanyaan, keterampilan merencanakan percobaan, dan keterampilan proses berhipotesis. Sehingga muncul permasalahan lain, yaitu bagaimana strategi guru dalam menerapkan guided inquiry pada tiap aspek KPS. Metode yang dilakukan dalam penelitian ini adalah Penelitian Tindakan Kelas (PTK) yang dilakukan sebanyak dua. Dari PTK tersebut di dapat hasil yang menunjukan bahwa terdapat peningkatan rata-rata hasil pembelajaran yaitu dari 5,15 (siklus I) menjadi 5,88 (siklus II), begitupun dengan setiap indikator KPS terjadi kenaikan, kenaikan terbesar ada pada keterampilan melakukan percobaan, hal ini menujukkan bahwa pembelajaran yang menggunakan proses untuk membentuk pengetahuan cenderung lebih bermakna. Sedangkan indikator keterampilan berkomunikasi mengalami peningkatan yang paling rendah, hal ini juga bisa menunjukkan bahwa siswa belum terbiasa untuk mengungkapkan ide, gagasan atau bahkan pengetahuan yang dimilikinya untuk di sampaikan pada orang lain yang sehingga orang lain pun memahaminya. Peningkatan ini di hitung berdasarkan rumus gain.
K-Graph: Knowledgeable Graph for Text Documents
Authors: Mittal Varsha , Gangodkar Durgaprasad , Pant Bhaskar 
Published: May 2021

Abstract
Graph databases are applied in many applications, including science and business, due to their low-complexity, low-overheads, and lower time-complexity. The graph-based storage offers the advantage of capturing the semantic and structural information rather than simply using the Bag-of-Words technique. An approach called Knowledgeable graphs (K-Graph) is proposed to capture semantic knowledge. Documents are stored using graph nodes. Thanks to weighted subgraphs, the frequent subgraphs are extracted and stored in the Fast Embedding Referral Table (FERT). The table is maintained at different levels according to the headings and subheadings of the documents. It reduces the memory overhead, retrieval, and access time of the subgraph needed. The authors propose an approach that will reduce the data redundancy to a larger extent. With real-world datasets, K-graph’s performance and power usage are threefold greater than the current methods. Ninety-nine per cent accuracy demonstrates the robustness of the proposed algorithm.

Simulation of a Motor Vehicle Momentarily Accelerating in Various Road Conditions
Authors: Zalewski Jarosław 
Published: May 2021

Abstract
In this paper some selected conclusions have been drawn from the simulated maneuver of a vehicle’s momentary acceleration in various road conditions. The aim of this paper was to answer the question whether the random irregularities of the road could decrease the final speed of the vehicle and cause it to deviate from the straight line motion and to what extent. These irregularities had three different maximum amplitudes which enabled analysis of vehicle’s acceleration on the less and the more uneven road. Also, almost the same and almost different profiles were assumed for the left and the right wheels of the vehicle’s model.
Some additional phenomena such as the ice on the road have been taken into account. The initial speed was 20 km/h and after 2 s the vehicle started to accelerate. Then, after 8 s the simulation stopped, which gave the whole simulation time equal to 10 s.

Is Mean Time to Failure (MTTF) Equal to Mean Time of Life for Unrepairable Systems?
Authors: Opyrchał Leszek 
Published: May 2021

Abstract
One of the most important reliability parameters is the mean time to failure (MTTF). It is widely accepted that the MTTF is equal to the mean time of life ET. This article shows that this is not necessarily true. Although for the most commonly used statistical distributions (such as exponential, Gaussian, chi-square, Fisher-Tippett distributions) the values of MTTF and ET are equal, this is not the case for the log-normal distribution. Similarity, some less commonly used distributions (such as Breit-Wigner distribution) may also require calculation adjustments resulting from MTTF ≠ ET. Ignoring this discrepancy, an erroneous MTTF value can be obtained.

Authors: Maksimovic Vesna , Jakovljevic Biljana 
Published: May 2021

Abstract
The SCORE model was calibrated according to mortality statistics for each European country. If it is used for the population aged 40–65, it will predict the possibility of fatal cardiovascular consequences that will appear after 10 years. The aim of this study was to investigate individual risk factors for cardiovascular complications in the adult population in the city of Belgrade. The study was designed as a cross-sectional study. Using Heart Score tool for determining of the total risk of CVD, could be projected to the age of 60, which may be of particular importance for guiding young adults, aged 20 to 30, with low absolute risk but already with an unhealthy risk profile, which will lead to a much higher risk as they age. In our study, predominately were present female participants without hypertension, then male and were dominate frequent non-smokers compared with smokers in male and female. Furthermore, in study population were more present smokers with longer duration of smoking (>10 years). After calculated Heart Score, we can see that 25.6% of respondents have a high risk of cardiovascular event, of which 19.6% high risk, 4.4% very high risk, and 1.6% extremely high risk of developing some an adverse fatal cardiovascular event. The present risk factors and high mortality and morbidity from cardiovascular disease indicate the need for taking preventive measures already in children, with the parallel implementation of population strategies and high risk.

Authors: Ibrahim Mohd Azizi , Nor Alias Mat , Hisham Raja Rizal Iskandar Raja 
Published: May 2021

Objective – Contractors’ All Risks (CAR) Takaful is completely different from CAR conventional insurance. CAR conventional insurance involves elements of usury (riba), gambling (maysir) and uncertainty (gharar) in their resources and operations which is prohibited by Shari’ah. This paper aims to investigate the relationship between attitude, awareness, understanding, religiosity, subjective norm, service quality and role of agents with contractor’s intention in choosing CAR Takaful products based on theory of planned behaviour (TPB). In addition, this paper aims to address the most influential factors that affect contractor’s intention in choosing CAR Takaful products. Design/methodology – Using primary data collection method, 421 questionnaires were distributed to target respondents comprising Bumiputera contractors in Malaysia except for Sabah and Sarawak, who are registered with CIDB from grade G1 to grade G7 and also a member of Persatuan Kontraktor Melayu Malaysia (PKMM). The data were analysed using Statistical Package for the Social Sciences (SPSS) software version 25. Results – This study's results reveal a significant relationship between attitude, awareness, understanding, religiosity, subjective norm, service quality, and role of agents with contractor’s intention in choosing CAR Takaful product. In addition, this research also verifies that attitude is the most important factor that affects contractor’s intention in choosing CAR Takaful products. Contribution – This paper will bring significant benefits to the Takaful operators and Takaful agents in Malaysia to formulate additional strategies, policies and service quality to attract Bumiputera contractors to choose CAR Takaful product.
An unusual presentation of mucocele on the tongue - a case report
Authors: Ramaswamy Dibin , Nandagopal Naveen 
Published: May 2021

Background:
Mucoceles are self-limiting mucus-containing cavities that is caused by mechanical trauma to the excretory duct of the gland, which leads to pooling of saliva into the surrounding tissues. They may vary according to its clinical presentations, depending on its depth of involvement. They are usually asymptomatic. Sometimes they may show change in size due to rupture and subsequent mucin accumulation. They more frequently occur in relation to the lower lip.

Case Presentation:
We present a case report of mucocele on the ventrolateral aspect of the tongue, which is a rare occurrence. Even though it clinically resembled a mucocele, diagnostic confirmation was done after histopathological examination.

Conclusion:
Although surgical excision is the treatment of choice, removal of all the adjacent minor salivary glands is required to prevent the recurrence. They pose a diagnostic and therapeutic challenge to the clinician as well as surgeon due to its clinical resemblance with other lesions of the tongue. So, a thorough clinical knowledge as well as the determination of varying aspects of the etiopathogenesis of these oral lesions is necessary for correct diagnosis and for the indication of appropriate treatment.

Increasing the Accuracy of Orbital Elements for a Satellite in a Low Earth Orbit under the Influence of Atmospheric Drag Using Adams-Bashforth Method
Authors: Ibrahim Rasha H. , Saleh Abdul-Rahman H. 
Published: May 2021

The perturbed equation of motion can be solved by using many numerical methods. Most of these solutions were inaccurate; the fourth order Adams-Bashforth method is a good numerical integration method, which was used in this research to study the variation of orbital elements under atmospheric drag influence. A satellite in a Low Earth Orbit (LEO), with altitude form perigee = 200 km, was selected during 1300 revolutions (84.23 days) and ASat / MSat value of 5.1 m2/ 900 kg. The equations of converting state vectors into orbital elements were applied. Also, various orbital elements were evaluated and analyzed. The results showed that, for the semi-major axis, eccentricity and inclination have a secular falling discrepancy, Longitude of Ascending Node is periodic, Argument of Perigee has a secular increasing variation, while true anomaly grows linearly from 0 to 360°. Furthermore, all orbital elements, excluding Longitude of Ascending Node, Argument of Perigee, and true anomaly, were more affected by drag than other orbital elements, through their falling as the time passes. The results illustrate a high correlation as compared with literature reviews in this field.

Shifting the Education Paradigm amid the COVID 19 Pandemic: Nursing Students’ Attitude to E Learning
Authors: Soriano Gil , Oducado Ryan Michael 
Published: May 2021

The unprecedented emergence of COVID-19 has disrupted education and has led to the rise of e-learning. The shift from the traditional delivery of instruction to online learning brings about varying perceptions that necessitates attention and exploration. This study examined nursing students’ attitudes towards e-learning in two selected nursing schools in the Philippines. This study used a descriptive cross-sectional design with 111 nursing students in a public and a private nursing school as study participants. The data were collected via an online survey tool and were analysed using the Mann-Whitney U test and the Kruskal-Wallis H test. The results indicated that most nursing students had intermediate computer competency (74.8%) and somewhat stable internet connection (66.7%). They generally had negative (40.5%) and ambivalent attitudes (30.6%) towards e-learning. The nursing students considered e-learning to be impersonal and to lack feeling (80.18%) and that it results in less student–teacher interaction (75.66%). There were no significant differences (p > .05) in the e-learning attitude according to the type of school, gender, ownership of a computer, level of computer competency, stability connection and internet usage. Although not statistically significant, those students with stable internet connections appear to have a better attitude towards e-learning. Ambivalence and negative attitudes seem to dominate nursing students’ attitudes towards e-learning in the times of the COVID-19 pandemic. Nursing schools must rectify the negative attitudes of students towards e-learning and must take measures to improve students’ experiences in the virtual learning environment to ensure that effective learning is never compromised amid the health crisis.
Ocular neuromyotonia caused by a recurrent sphenoidal ridge meningioma
Authors: Shingai Yuto , Endo Hidenori , Endo Toshiki , Osawa Shin-ichiro , Nizuma Kuniyasu , Tominaga Teiji 
Published: May 2021

Background:
Ocular neuromyotonia (ONM) is a rare ocular motility disorder characterized by involuntary paroxysmal extraocular muscle contraction and is caused by radiation therapy, vascular compression, and inflammatory disease. This study includes a rare case of ONM caused by a recurrent meningioma.

Case Description:
A 56-year-old man presented with diplopia due to the right oculomotor nerve palsy caused by a sphenoidal atypical meningioma, with improved symptoms after initial surgery. During the next 7 years, he underwent local radiation therapy, second surgery, and Gamma Knife radiosurgery to control the tumor’s repetitive recurrence around the right anterior clinoid process. After these treatments, residual tumor was controlled for the next 3 years. However, 3 months after his last visit, he started to suffer from the right ONM and visual disturbance. The magnetic resonance imaging results revealed a rapid growth of the posterior part of the residual tumor, involving the right oculomotor nerve. The third tumor resection was performed to prevent further aggravation of the symptoms. Decompression of the right oculomotor nerve was achieved, and ONM disappeared immediately after surgery.

Conclusion:
If nerve compression by the tumor is clearly indicated with the neuroradiological assessment, surgical intervention is the treatment of choice to improve ONM.
