Authors: F. Catapan ab Márcio , Lucia Okimoto Mateus Villas Boas Roberto Waldhauer Maria
Published: February 2022

Studies of the physical characteristics of man and their dimensional variations have interested researchers since antiquity. In relating to the human head, the measures that are analyzed to make your sizing artifacts that protect her from possible accidents, are tied just as its circumference. In the military area, studies report that approximately half of the deaths in the battle fields is due to projectiles triggered in the soldier's head. However, other studies show that this artifact after a few minutes in continuous use, it becomes heavy and unstable for many users. Ie, proves itself that some soldiers do not wear a helmet when necessary is because it bothers them. Therefore, the objective of this paper is to research the height of the human head, in area the ballistic helmet, to verify whether this is significant or not height variation. Thus, it can be highlighted the need for a new ballistic helmet design to serve this dimensional variation of the height of the human head. For it is made a pilot survey and analyzed the anthropometric measurements of the human head using conventional instruments. Next analyzed the values and found that the means are different, proving that if the artifact of study is not adequate for use on the battlefield for all users.

Published: February 2022

The aim of the research presented in this paper is to identify behavior and generic expectations of elderly people (mean=65 years) relevant to Human-Machine Interface (HMI) in the context of health. Our work is based on two industrial cases of health care services. In one case, we conducted user tests on HMI coupled with an eye-tracker to identify one behavior pattern (16 subjects). And in both industrial cases, we realized interviews that reveal generic expectations in terms of information from seniors (16+8 subjects). Then, this double-case approach has enabled us to emphasize the explorer behavior of seniors and expectations “in the periphery of health” with a need for both social and reassuring projection. Based on our results, we propose recommendations for HMI design in our context and which levers (action parameters) for design in other fields.
Reformulation of the Epistemology of Islamic Education: Examine Noeng Muhadjir's Thoughts
Authors: Hamka
Published: February 2022

This article shows that revelation is a barometer of the truth of science, as can be concluded from Noeng Muhadjir's thoughts. Any scientific product cannot be accepted if it is in apparent contradiction with the qat'i nash. This article is classified as qualitative research that uses a library research model. The primary data source is the works of Noeng Muhadjir, especially the article entitled, "Epistemology of Islamic Education The Theoretical-Philosophical Approach", contained in the book Reformulation of Islamic Education Philosophy, and "Education in Perspective The Koran: A Micro Review”, contained in the book Education in the Perspective of the Koran. Other works are used as support. The method used in this paper is discourse analysis. The conclusion that can be drawn from the discussion results is that Noeng Muhajir takes the basis as an epistemological basis for Islamic education on the philosophy of metaphysical realism (popper) and phenomenology (ponty) as postulates of anthology and axiology. Noeng Muhadjir's ideas were driven by the spirit of bringing together science and revelation while maintaining the scientific characteristics of science and the absolute truth of revelation.

Nyiragongo, remains one of the most active volcanoes in the Virunga chain. It is feared for its permanent activity. It has fissural and fracturing characteristics. The carbon dioxide released by Nyiragongo is regularly monitored on the southern flank of the volcano. Five sampling points were taken into consideration during our study. The data collected over a two-year period (since 2019) prior to the eruption of 22 May 2021 show a certain change in the monitoring curves. All the sampling points included in this work show an increase in carbon dioxide concentration in October 2020, seven (7) months before the event. This rise in carbon dioxide concentration in the southern fractures of Nyiragongo reflects in some way the degree of (intense) activity in the magma reservoir, which also induced a magmatic rise. Of the five points monitored, four were found to be hyperascending, even increasing by more than twice the concentration usually measured; all the Buragura sites showed this difference.

Эффективная защита нашей окружающей среды во многом зависит от качества доступной информации, используемой для принятия соответствующего решения. Проблемы возникают, когда объем доступной информации огромен и неоднороден (то есть поступает из множества раз- личных дисциплин или источников), а их качество невозможно определить заранее. Другой связанный с этим вопрос - это динамический характер проблемы. Компьютеры занимают центральное место в современной защите окружающей среды при выполнении таких задач как мониторинг, анализ данных, обмен данными, хранение и поиск информации, поэтому было естественно попытаться интегриро- вать и улучшить все эти задачи с помощью методов искусственного интеллекта, основанных на зна- ниях.

Published: February 2022

В статье рассмотрены результаты исследования процесса переработки отмытой ка- лийной руды месторождения Челкар с целью получения безбалластного калийного удобрения. Изучена эффективность двух- и трехкратной отмывки руды от солей натрия для определения оптимально- го режима обогащения руды по калию. Установлено, что целесообразно проводить двукратную от- мывку руды промывной водой, при которой обеспечивается максимальное содержание в руде калия и минимальное содержание солей натрия. Эффективность отмывки подтверждается результатами рентгенографического анализа руды после второй отмывки. Прокалка руды приводит к дегидрата- ции кристаллогидратов минералов и возрастанию содержания в ее составе основных компонентов. Растворение прокаленной руды при температурах 50 и 90°С приводит лишь к частичному переходу в раствор солей калия и магния при полном растворении остаточного количества солей натрия. Для достижения полного растворения сульфатов калия и магния, являющихся целевыми компонентами для получения минерального удобрения, требуется изучить химические методы превращения.

This paper presents an extensive comparison between public and private natural gas-fired units in managing the unit commitment problem in the context of the Greek electricity market. Using a unique hourly dataset from 2015–2019, our approach utilizes risk-weighted performance metrics—Cash Flows at Risk (CFaR) and Risk Weighted Return (RWR)—to analyze performance across the public and private units. Empirical findings indicate that publicly owned natural gas-fired units outperform privately owned natural gas-fired units in terms of operational efficiency, however the efficiency of privately owned natural gas-fired units is growing at a faster pace and is expected to surpass the efficiency of public units within 2 or 3 years.
E-prevention in a rural school on the example of the "Edu_akcja Enter" programme preventing risky behaviours among students
Authors: Chańko-Kraszewska Anna
Published: February 2022

Prevention of risky behaviours in children and adolescents consists in organizing activities, addressed to young people, the aim of which will be to eliminate or reduce the frequency of showing anti-health or problem-related behaviours by them. It is implemented not only by institutions and organizations that provide psychological and therapeutic help or preventive activities, but also by schools. During the COVID-19 pandemic, which caused enormous changes in the psychosocial functioning of adolescents, the preventive activity of schools changed its dimension and was transferred to a virtual space. Its example, created in one of rural primary schools, is the "Edu_akcja ENTER" project addressed to children and youth from grades IV-VIII, preventing risky behaviours among students and using distance learning methods. In its assumptions, it uses the philosophy of positive prevention, based on the use of resources and potential of students in the process of their education and upbringing.
The aim of this article is to outline the problem of undertaking risky behaviours by children and adolescents in the context of remote education and to describe a preventive project implemented in primary schools in the Dobrzyniewo Duże commune, which may be an inspiration for teachers, educators, pedagogues who carry out tasks in the field of counteracting risky behaviours of students.
Beliefs of young people about the long-term unemployed in the context of social assistance
Authors: Czechowska-Bieluga Marta
Published: February 2022

Introduction: The aim of the article is to present the beliefs of school youth and university students about the long-term unemployed in the field of social assistance, and to identify the selected factors determining such beliefs.
Method: The study group consisted of 1084 persons, including 588 secondary school students and 496 university students of social sciences. In order to examine the beliefs of youth about people at risk of social exclusion, the Likert scale was used (A. Kanios, M. Czechowska-Bieluga, A. Weissbrot-Koziarska, R. Krawczyk and P. Zielińska).
Results: The beliefs of the respondents are characterised by an average and low level of confidence, lower in the case of the school youth compared to university students, which suggests that there is some degree of ambivalence in the first group, and the risk of revealing stigmatising elements in the second group. Variables such as the level of education, age, sex, and place of residence significantly differentiate the beliefs of the respondents.
Conclusions: Considering enormous significance of the secondary school education stage for shaping value and normative foundations for the implementation of future professional tasks, the research results may be used in planning modification activities based, among others, on direct contact with the subject of the attitude. On the other hand, the surveyed university students of social sciences may, in the future, take up employment in various forms of assistance and support for people at risk of social exclusion. Therefore, it is worth minimizing the stigmatising elements in terms of their beliefs towards the unemployed, as those elements may be a factor that interferes with their effective actions.

Authors: Demirbilek Nevzat
Published: February 2022

OBJECTIVE: This study aimed to investigate the eustachian tube dysfunction (ETD) of patients with obstructive sleep apnea syndrome (OSAS) using the Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7). METHODS: The study included 96 patients (78 males, 18 females; mean age 39.4±12.2 years; range 18 to 64 years) diagnosed with OSAS by polysomnographic evaluation. All patients were administered the ETDQ-7. Age, sex, presence of septum deviation, Epworth Sleepiness Scale, apnea-hypopnea index (AHI), lowest oxygen saturation, and oxygen desaturation index parameters were recorded. The patients were divided into mild, moderate, and severe OSAS groups according to the AHI score. The parameters of the cases in each group were compared, and their correlation with the ETDQ-7 scores was evaluated. RESULTS: The fourth question score and the total score in the group with severe OSAS were significantly higher than the groups with mild and moderate OSAS (p<0.05 for all). The fourth question score and the total score were significantly higher in the group with moderate OSAS than the group with mild OSAS (p<0.05 for all). There was a significant positive correlation between the oxygen desaturation index and the scores of questions 1, 3, 4, 6, and 7 and the total score (p<0.05 for all). CONCLUSION: Questionnaire scores were higher in patients with severe OSAS compared to mild to moderate OSAS patients. Based on this data, we would like to emphasize that OSAS cases may develop ETD and other related pathologies.

OBJECTIVE: This study aimed to investigate the distribution and possible causes of objective tinnitus in geriatric patients. METHODS: A total of 242 patients (101 males, 141 females; mean age: 71.5±13.3 years) over 65 years who were admitted to our outpatient clinic with the complaint of tinnitus between March 2021 and October 2021 were included in the retrospective study. The clinical history and the etiology of tinnitus were investigated. The pure tone audiometry tests were evaluated to determine whether there was a loss in any frequency. The associations between the presence of objective tinnitus, age, sex, hearing loss, and comorbid diseases were analyzed. RESULTS: The prevalence of objective tinnitus was 13.6% in geriatric patients. The relation between objective tinnitus with the male sex and lower age was statistically significant (p<0.001 and p<0.001, respectively). No association was found between objective tinnitus and hearing loss or other comorbid diseases (p=0.727 and p=0.658, respectively). CONCLUSION: Objective tinnitus may be less common than subjective tinnitus; however, a detailed medical history and physical examination is recommended, particularly in males and younger patients. The most common cause of objective tinnitus was vascular diseases.

Access to finance plays a major role in the entrepreneurship development and economic growth of any country. It encourages new entrepreneurial initiatives. Timely access to finance sustains the survival and growth of micro, small, and medium enterprises (MSMEs). The purpose of this paper is to explore the challenges of access to finance faced by the MSMEs and to analyze their impact on their business performance. The survey was conducted in 400 MSMEs from various industrial clusters across India. The samples were selected using the quota sampling technique. The conceptual framework was developed and tested using the structural equation model (SEM). Results show that firm attributes, sources of finance, and the life cycle of an MSME have a significant positive impact on its access to finance, whereas financial obstacles have a negative impact that prevents the growth of MSME and affects the economic growth of the nation.

Published: February 2022

Diffuse optical tomography (DOT) is favorable to analyze physical records in organic tissue with a specific purpose by means of a method related to the forward problem and the inverse solution. This study develops morphological soft tissue realization using an image reconstruction algorithm constructed on multifrequency DOT in Near-Infra-Red (NIR) wavelength. Forward problem solves the Diffusion Equation to compute the optical flux distributed in the phantom geometrical model. Inverse solution, the image is reconstructed using the absorption and reduced scattered coefficients under different boundary conditions. The inverse image reconstruction algorithm is tested for several simulation, with variation in background contrast ratios for different frequencies are simulated. The image reconstruction in DOT eliminates spatial resolution by optimizing source-detector separation and modulation intensities of the source.

Authors: Seong Daehee , An Gyubaek , Park Jong-ung
Published: February 2022

The characteristics of welding residual stress distribution in high-strength steel for offshore structures were evaluated based on the effect of constraint. It is well known that high-strength steel exhibits a high welding residual stress, and the welding residual stress is a significant factor for evaluating unstable fractures. Test specimens were manufactured by applying different constraint conditions. The constrainted and unconstrainted specimens were welded with the same welding consumables and conditions to evaluate the welding residual stress distribution characteristics. The cutting method was applied to assess the welding residual stresses of both specimens. The results showed that the welding residual stress at the heat-affected zone of the unconstrainted specimen decreased compared with that of the constrainted specimen. However, angular distortion occurred in the unconstrainted specimen instead of reduced welding residual stress.

Sialendoskopske tehnike predstavljajo novo paradigmo, ki je bistveno spremenila zdravljenje zastojne bolezni žlez slinavk. Epidemija covida-19 predstavlja nov izziv za zdravstveni sistem sleherne države in postavlja na preizkušnjo številne, predvsem elektivne kirurške metode zdravljenja. Kirurški posegi v področju glave in vratu in še posebej v ustni votlini predstavljajo hudo tveganje za prenos covida-19. Pri izvajanju sialendoskopije oziroma sialendoskopsko asistirane operacije sta kirurška ter anesteziološka ekipa izpostavljeni slini in refleksom občutljivega anatomskega področja ust oziroma zgornjih dihal in prebavil. Ostaja vprašanje, kolikšno je tveganje glede na fazo operacije, vrsto anestezije, uporabljeno osebno varovalno opremo ter trenutno epidemiološko situacijo covida-19. V času pandemije covida-19 smo na Kliniki za otorinolaringologijo in cervikofacialno kirurgijo Ljubljana izvajali le nujne, kasneje pa tudi elektivne sialendoskopske in sialendoskopsko asistirane posege. Menimo, da je v času obvladljive epidemiološke situacije sialendoskopska kirurgija ob upoštevanju indikacij in zaščitnih ukrepov lahko varna za bolnika in izvajalca.

Authors: Kim Young Geun , Yoon Sung Ho , Oh Jae Wook , Kim Dae Hwan , Lee Keun Cheol
Published: February 2022

Background: Intermaxillary fixation (IMF) is a technique that allows for the reduction and stabilization of mandibular fractures. Several methods of IMF, such as self-tapping screws or arch bars, have been developed. This study aimed to validate the usefulness of IMF with a self-tapping screw compared to IMF with arch bars with focus on the patients’ perspective.Methods: We retrospectively reviewed the medical records of all patients who were treated for mandibular fractures at our hospital between August 2014 and February 2021. A total of 57 patients were enrolled in this study. Thirteen patients were excluded from the analysis: three patients were lost to follow-up, and 10 patients did not undergo IMF. Finally, 44 patients were analyzed, of which 31 belonged to the arch bar group, and 13 belonged to the screw group. Patient discomfort and pain during IMF application and removal were analyzed using a patient self-assessment questionnaire. The surgeon also assessed oral hygiene, IMF stability, and occlusion.Results: We applied IMF to 34 men (77%) and 10 women (23%). The mean age of the patients was 37.3 years. The most common fracture site was the angle (30%), followed by the parasymphysis (25%), the body (23%), the condyle (11%), and the ramus (11%). Patient discomfort and oral hygiene were statistically favorable in the screw group. The IMF application time was statistically shorter in the screw group (p< 0.001). IMF stability was not statistically different between the two groups. The pain score during IMF removal was lower in the screw group (p< 0.001).Conclusion: Compared to arch bars, IMF screws provide more comfort during the IMF period, help maintain favorable oral hygiene, and have a shorter application time. From the patient’s perspective, IMF screws are an excellent alternative to conventional arch bars when applicable.
