Authors: AKSOY Zahide , EROL Saime 
Published: August 2021

Objective: Digital game addiction is a concern that threatens public health around the world, especially in adolescents. This study was conducted to determine the relationship between digital game addiction and lifestyle behaviors in adolescents.
Methods: The research was carried out in the 2017-2018 academic year with 2001 students from three high schools offering different types of education selected by cluster sampling method in Istanbul/Maltepe district. Data were collected by using the Introductory Information Form, Game Addiction Scale for Adolescents and Adolescent Lifestyle Profile Scale. Data were evaluated in computer environment. Descriptive data were shown with numbers, percentages and means. The relationship between game addiction and independent variables was evaluated by chi-square test, Mann-Whitney U test, Pearson Correlation Analysis and Logistic Regression Analysis.
Results: 22.4% of adolescents were determined to be addicted to digital games. The mean scores of health responsibility, nutrition, interpersonal relationships and stress management of adolescents who had game addiction were significantly lower than the adolescents without game addiction. Digital game addiction rates were significantly higher in boys, vocational high school students, ninth grade students, and in those who described that their family had low income, that they had very poor relations with their families/friends, that they had very poor living conditions and that they were generally unhappy.
Conclusions: It was determined that game addiction negatively affected adolescents' lifestyle behaviors, and there was a negative, low to moderately significant correlation between interpersonal relationships and stress management and game addiction.

Authors: EKİCİ Ömer 
Published: August 2021

Objective
Airway management in maxillofacial injuries is quite complex and involves many difficulties. The aim of this study is to evaluate the knowledge level of medical faculty students about airway management in maxillofacial injuries.
Methods
This cross-sectional study was conducted on fifth and sixth-grade students of the Faculty of Medicine, Afyonkarahisar Health Sciences University. After the literature review, a questionnaire was prepared to measure the knowledge level of the students about airway management in maxillofacial trauma. Two hundred eighty students participated in the study.
Results
Thirty percent of the students stated that they performed laryngeal mask airway (LMA), 61.11% orotracheal intubation, and 17.77% nasoendotracheal intubation. Thirty four point forty four percent of the students stated that they did not do any of these applications. Only 52.2% of the students stated that they used a traditional laryngoscope with Macintosh blades. While 81.1% of the students stated that they did not intubate at all in a patient with maxillofacial trauma, and 74.4% thought that a patient with maxillofacial trauma did not have the education and skills to perform intubation comfortably.
Conclusion
Results of the study reveal that students' knowledge and experience in airway management in emergencies such as maxillofacial trauma were insufficient. This deficiency was especially about the tools and methods used to provide airway patency.
Keywords

Published: August 2021

PLI (Peta Laut Indonesia) dan ENC (Electronic Nautical Chart) adalah produk utama Pushidrosal sebagai lembaga hidrogafi yang dipergunakan untuk keselamatan navigasi. Konvensi SOLAS (Safety of Life at Sea) mengatur bahwa peta navigasi laut yang legal adalah produk dari lembaga hidrografi yang menjadi perwakilan negara di IHO (International Hydrographic Organization). IMO (International Maritime Organization) telah mewajibkan program ECDIS (Electronic Chart Display Information System) mandatory terutama bagi kapal – kapal yang digunakan untuk pelayaran internasional. Hal tersebut mendorong semakin berkembangnya ENC (Electronic Nautical Chart) sebagai produk utama lembaga hidrografi. Pushidrosal mendistribusikan ENC dengan standar S-63. Standar ENC S-63 menjamin keamanan data melalui metode enkripsi. KAL (Kapal Angkatan Laut), Pangkalan Angkatan Laut dan Marinir memerlukan peta laut yang di-update secara periodik sebagai data referensi wilayahnya. Idealnya unit – unit tersebut mempunyai ECDIS agar dapat mengakses ENC S-63 sebagai produk yang update setiap Bulan , namun terkendala oleh biaya yang mahal. Hambatan tersebut kini dapat diatasi dengan adanya software ECS (Electronic Charting System) OpenCPN yang dilengkapi dengan S-63 plugin. Dengan kemampuan tersebut, OpenCPN memberikan solusi bagi KAL, Pangkalan dan Marinir untuk dapat mengakses dan memanfaatkan produk ENC S-63, sehingga peta laut yang menjadi referensi adalah peta digital yang selalu dapat di-update secara periodik dengan mudah.

The Internet of Things (IoT) gives a strong structure for connecting things to the internet to facilitate Machine to Machine (M2M) communication and data transmission through basic network protocols such as TCP/IP. IoT is growing at a fast pace, and billions of devices are now associated, with the amount expected to reach trillions in the coming years. Many fields, including the army, farming, manufacturing, healthcare, robotics, and biotechnology, are adopting IoT for advanced solutions as technology advances. This paper offers a detailed view of the current IoT paradigm, specifically proposed for robots, namely the Internet of Robotic Things (IoRT). IoRT is a collection of various developments such as Cloud Computing, Artificial Intelligence (AI), Machine Learning, and the (IoT). This paper also goes over architecture, which would be essential in the design of Multi-Role Robotic Systems for IoRT. Furthermore, includes systems underlying IoRT, as well as IoRT implementations. The paper provides the foundation for researchers to imagine the idea of IoRT and to look beyond the frame while designing and implementing IoRT-based robotic systems in real-world implementations.
Des frictions dans l’espace pétrolier
Authors: Buu-Sao Doris 
Published: August 2021

La rencontre des peuples autochtones avec des entreprises minières ou pétrolières est souvent appréhendée au prisme de la confrontation. Si la fréquence des contestations est indéniable, notamment en Amérique latine, les interactions nées de l’implantation d’industries extractives en milieu rural ne se réduisent pas à l’opposition frontale : parce qu’elles s’ancrent nécessairement dans des espaces où elles doivent composer avec leur entourage social, ces industries donnent souvent lieu à des interactions plus routinières et pacifiées, porteuses de profonds changements. C’est ce qu’étudie cet article, qui s’appuie sur une enquête ethnographique menée au Pérou, dans des villages autochtones de l’Amazonie confrontés au développement d’un site pétrolier emblématique de la région. Il analyse comment cette industrie extractive ancrée localement contribue à la normalisation d’une société frontalière. Tenant compte du caractère relationnel des interactions qui se jouent aux abords des sites extractifs, il appréhende cette topographie politique comme un « espace pétrolier » où se jouent des transformations profondes mais ambivalentes, qu’il s’agisse de l’importation de la discipline salariale dans les pratiques productives, de la restructuration hiérarchisée du collectif villageois, ou de l’inscription dans l’ordre territorial national propice à une certaine marchandisation du foncier amazonien.

Authors: Muangwong Pooriwat , Chitapanarux Imjai , Ya-in Charin , Klibngern Hanpon , Kongmebhol Pailin 
Published: August 2021

Background:
Kimura’s disease is a rare inflammatory disease that usually appears in head and neck region. We reported natural history of the disease and treatment outcome of radiotherapy (RT) in Chiang Mai University Hospital.

Methods:
A retrospective review was performed for all Kimura’s disease patients treated with radiotherapy at our center between 2002 and 2017.

Results:
A total of 20 patients with Kimura’s disease were reviewed. There were 14 men and 6 women. All patients presented with the mass in head and neck region. Eleven patients were treated with a definitive intent with RT, 9 patients were treated with RT after recurrence from other modalities. All patients were treated with local external beam RT with 2 Gy per fraction to a median total dose of 30 Gy (range 30–40). The median follow-up time was 4 years (range 1–16.5 years). One patient died from HIV opportunistic infection after 1.5 year of radiation with complete response of Kimura’s disease. Most of the patients responded to radiotherapy and controlled the disease at the time of analysis. Two patients had multiple recurrences at new areas outside radiotherapy field. Skin toxicity grade 1 was the most common late side effect which was found in 8 (44%) patients. We did not find severe late toxicity or second malignancy in this patient cohort.

Conclusion:
Good local control of Kimura’s disease can be achieved, with a radiation dose of 30–40 Gy, with insignificant late toxicities. We suggest that radiotherapy should be one of the treatments of choice for Kimura’s disease both in primary or recurrence setting.
Indigenous Groin Board Immobilization Reduces Planning Target Volume Margins in Groin Radiotherapy
Authors: Krishnatry Rahul , Mangaj Akshay , Bhajbhuje Rajesh , Murthy Vedang 
Published: August 2021

Purpose:
To quantify the relative motion of pelvic and groin lymph nodes (PLN and GLN) and define indicative margins for image-guided radiotherapy based on bony anatomy for the frog-leg position (FLP) and groin immobilization board (GIB).

Materials and Methods:
Twenty patients with planning computed tomography (CT) scan and on treatment cone beam CTs (median = 8) for groin and pelvic radiotherapy were included in the study. Of these nine were treated with FLP and eleven with GIB. The PLN and GLN regions on the left and right were outlined in each scan. Systematic and random uncertainties were determined along with correlations between the motions of these regions. The clinical target volume to planning target volume (PTV) margins required to take motion into account was calculated for each immobilization.

Results:
The mean shifts for PLN and GLN were lesser but not statistically lower using GIB over FLP. There was significant concordance in the vertical, longitudinal and lateral motion of the pelvis and right groin (P = 0.015, 0.09 and 0.049, respectively), pelvis and left groin (P = 0.001, 0.048, and 0.006, respectively) and between left and right groin (P = 0.013, 0.01 and 0.07, respectively) for FLP and not GIB. The PTV margins required by Van Herk and Stroom's formula were reduced from 11 mm and 9 mm to 6 mm and 5 mm for pelvis; 12 mm and 11 mm to 7 mm and 6 mm for groin, respectively, using FLP over GIB.

Conclusions:
GIB brings concordance in shifts between pelvis and groin and between bilateral groins, thereby reducing the required PTV margins.
The Effect of Algorithms on Dose Distribution in Inhomogeneous Phantom
Authors: Tuğrul Taylan 
Published: August 2021

Background:
The aim of this study is to evaluate the dose calculation algorithms commonly used in TPS by using MC simulation in the highly different inhomogeneous region and in the small fields and to provide the following uniquely new information in the study of correction algorithm.

Materials and Methods:
We compared the dose distribution obtained by Monaco TPS for small fields.

Results:
When we examine lung medium, for four different fields, we can see that the algorithms begin to differ. In both the lung and bone environment, the percentage differences decrease as the field size increases. In areas less than or equal to 3x3 cm2, there are serious differences between the algorithms. The CC algorithm calculates a low dose value as the photon passes from the lung environment to water environment. We can also see that this algorithm measures a low dose value in voxel as the photon passes from the water medium to the bone medium. In the transition from the water environment to the bone environment or from the bone environment to the water environment, the results of the CC algorithm are not close to MC simulation.

Conclusion:
The effect of the algorithms used in TPS on dose distribution is very strong, especially in environment with high electron density variation and in applications such as Stereotactic Body Radiotherapy and Intensity Modulated Radiotherapy where small fields are used.

Authors: Cheraghian Mojtaba , Pourfallah Tayyeb , Sabouri-Dodaran Amir Abbas , Gholami Mehrdad 
Published: August 2021

Purpose:
The aim of this research was to calculate the fluence, dose equivalent (DE), and kerma of thermal, epithermal and fast photoneutrons separately, within ICRU soft-tissue-equivalent phantom in the radiotherapy treatment room, using MCNPX Monte Carlo code.

Materials and Methods:
For this purpose, 18 MV Varian Linac 2100 C/D machine was simulated and desired quantities were calculated on the central axis and transverse directions at different depths.

Results:
Maximum fluence, DE and kerma of total photoneutrons on central axis of the phantom were 43.8 n.cm-2.Gy-1, 0.26, and 3.62 mGy.Gy-1, at depths 2, 0.1, 0.1 cm, respectively. At any depth, average of fluence, DE and kerma in the outer area of the field were less than the inner area and in general were about 72%, 52%, and 45%, respectively.

Conclusion:
According to this research, within the phantom; variation of fluence, DE and kerma in transverse direction were mild, and along the central axis at shallow area were sharp. DE of fast photoneutrons at shallow and deep areas were one order of magnitude greater than thermal photoneutrons.
Comparison of Phase-Gated and Amplitude-Gated Dose Delivery to a Moving Target using Gafchromic EBT3 Film
Authors: Savanović Milovan , Jaroš Dražan , Foulquier Jean Noel 
Published: August 2021

Introduction:
This study compared phase-gated and amplitude-gated dose deliveries to the moving gross tumor volume (GTV) in lung stereotactic body radiation therapy (SBRT) using Gafchromic External Beam Therapy (EBT3) dosimetry film.

Materials and Methods:
Eighty treatment plans using two techniques (40 phase gated and 40 amplitude gated) were delivered using dynamic conformal arc therapy (DCAT). The GTV motion, breathing amplitude, and period were taken from 40 lung SBRT patients who performed regular breathing. These parameters were re-simulated using a modified Varian breathing mini phantom. The dosimetric accuracy of the phase- and amplitude-gated treatment plans was analyzed using Gafchromic EBT3 dosimetry film. The treatment delivery efficacy was analyzed for gantry rotation, number of monitor unit (MU), and target position per triggering window. The time required to deliver the phase- and amplitude-gated treatment techniques was also evaluated.

Results:
The mean dose (range) per fraction was 16.11 ± 0.91 Gy (13.04–17.50 Gy) versus 16.26 ± 0.83 Gy (13.82–17.99 Gy) (P < 0.0001) for phase- and amplitude-gated delivery. The greater difference in the gamma passing rate was 1.2% ±0.4% in the amplitude-gated compared to the phase gated. The gantry rotation per triggering time (tt) was 2° ±1° (1.2°–3°) versus 5° ±1° (3°–6°) (P < 0.0001) and MU per tt was 10 ± 3 MU (6–13 MU) versus 24 ± 7 MU (12–32 MU) (P < 0.0001), for phase- versus amplitude-gated techniques. A 90 beam interruption in the phase-gated technique impacted the treatment delivery efficacy, increasing the treatment delivery time in the phase gated for 1664 ± 202 s 1353–1942 s) compared to 36 interruptions in the amplitude gated 823 ± 79 s (712–926 s) (P < 0.0001).

Conclusion:
Amplitude-gated DCAT allows for better dosimetric accuracy over phase-gated treatment patients with regular breathing patterns.
