Authors: Alcantara Olivia G.
Published: July 2023

Abstract: Education at any level has normally been based on some image of the future; that was not impossible in a world that was changing slowly like what is happening now, that learning in the new normal is a challenge for the teachers, students and even parents. And since going back to the “normal” we’re all accustomed to isn’t going to happen anytime soon, let’s all do the best we could to adjust and make this current situation work. Today, educators are preparing learners for a world that we cannot predict, and self-directed learning has become essential foundation for 21st century learners. This study was designed to determine the effect of Self-Directed Activity as Remedial Approach to Selected Grade 9 Students in Antipolo National High School. Moreover, the study aimed to answer the following problems: 1.) the performance of students before the intervention; 2.) the performance of students in the posttest 3.) and the significant difference between the pretest and post-test of the students. Quantitative approach was used to measure its effectivity, and experimental design was employed to the study. The participants of the study were the 50 students from handled sections of the researcher in Antipolo National High School and they were selected through random sampling. Data were gathered through using Pretest and Post-test result with teacher-made test as the main instrument which consist of fifty-item test which were based under the most essential competencies (MELC) of DepEd. Mean and standard deviation were used to determine the performances of the participants and dependent t-test was applied in order to get the result of the performance of the students in both pretest and post-test. And based from the result, a significant difference occurred from the pretest and post-test of the respondents. Based from the result of the study, the following conclusions were drawn such as; there is no significant difference in the pretest scores of the students, self-directed activity was effective based on the increase in the posttest results after the intervention was made. The highest posttest score attained by the students were on the range of 46 to 50 and the lowest was in the range of 26 to 30. The mean scores of 38.20 and standard deviation of 5.19 respectively, the posttest results of the respondents was significantly different and that the use of self-directed activity approach produces significantly higher scores among the students. And the used of self-directed activity as an approach for remediation in teaching selected grade 9 students was effective since the mean in the posttest was higher than the mean in the pretest.

Authors: Castro Charles Alves de
Published: July 2023

Este estudo investigou a relação entre os seis fatores de personalidade HEXACO e a Escala Satisfação com a Vida (ESV) durante a pandemia da COVID-19. Os seis fatores de personalidade HEXACO, ou dimensões, incluem Honestidade-Humildade (H), Emocionalidade (E), Extroversão (X), Amabilidade (A), Conscienciosidade (C) e Abertura à Experiência (O). Nesta pesquisa, o grau de Satisfação com a Vida (ESV) foi a variável dependente. A população amostral deste estudo é representada por (N=343) participantes, nos quais a maioria dos sujeitos, 28,9%, possui entre 30 e 39 anos de idade, 32,7% são do sexo masculino, 67,1% do sexo feminino e 3% outros. Os resultados confirmaram correlações positivas entre a Satisfação com a Vida (ESV) e a Extroversão (X) (p<.001) e a Conscienciosidade (C) (p<.01); houve uma correlação negativa entre a Satisfação com a Vida (ESV) e a Emocionalidade (E) (p < .05). Além disso, houve uma relação negativa entre a Satisfação com a Vida (ESV) e o impacto da COVID (p < .001), o que apoiou nossa hipótese de que haveria uma relação positiva entre ESV, Extroversão (X) e Conscienciosidade (C), haveria uma relação negativa entre a Satisfação com a Vida (ESV) e a Emocionalidade (E), e haveria uma relação negativa entre o impacto da COVID e a Satisfação com a Vida (ESV). No entanto, não houve relações estatisticamente significativas entre a Satisfação com a Vida (ESV) e a Honestidade-Humildade (H), a Abertura à Experiência (O) ou a Amabilidade (A). Em geral, os resultados apoiam os fatores de personalidade HEXACO para prever a Satisfação com a Vida (ESV), embora houvesse algumas limitações no contexto irlandês. Recomenda-se mais pesquisas utilizando os 200 itens HEXACO e uma amostra maior.
ANÁLISE DO CONFLITO ENTRE A VERDADE BIOLÓGICA E O DIREITO AO PARTO ANÔNIMO DA MULHER GESTANTE
Authors: Júnior Júlio Alves Caixêta , Santos Diovana Késsia de Castro
Published: July 2023

O parto anônimo é uma prática que permite que mulheres não pratiquem abortos ilegais, dos filhos que não desejam ou não podem assumir a maternidade, e assim dar à luz sem revelar sua identidade. A pesquisa dedica-se a seguinte problemática: no sistema jurídico brasileiro, entre a verdade biológica e o direito ao parto anônimo da mulher gestante, qual direito se sobrepõe? Desta forma, o objetivo deste trabalho é analisar no sistema jurídico brasileiro o conflito entre a verdade biológica e o direito ao parto anônimo da mulher gestante. Para conquistar esse objetivo, quanto à metodologia utilizada, a pesquisa é uma pesquisa normativa-jurídica, desenvolvida pelo método científico histórico, em uma pesquisa bibliográfica; sendo realizado um estudo sistematizado, desenvolvido a partir do que já foi escrito sobre a temática em textos acadêmicos em uma abordagem qualitativa, em fontes primárias e secundárias, aplicando-se o método indutivo e dedutivo. A análise dos documentos pesquisados foi por meio da Teoria de Análise de Conteúdo, utilizada para o tratamento dos dados coletados. A pesquisa, inicialmente, analisa o direito a verdade biológica em confronto ao direito à liberdade da mulher gestante no parto anônimo. Em seguida, analisa os projetos de lei que tentaram a institucionalização do parto anônimo no ordenamento jurídico brasileiro em sequência a uma abordagem dos aspectos legais do parto anônimo no Brasil. A partir da pesquisa normativa jurídica desenvolvida, constata-se que o caminho mais protegido para permitir uma decisão livre de qualquer coerção, sem ferir a verdade biológica é fornecer assistência e informação para conscientizar mais profundamente as mulheres sobre a importância dos métodos anticoncepcionais, além de facilitar o acesso a esses métodos, com o objetivo de evitar gravidezes não planejadas, vez que, a legislação garante a verdade biológica em detrimento ao parto anônimo.
LOS INSTRUMENTOS LÍTICOS PROVENIENTES DE DEPÓSITOS ESTRATIGRÁFICOS DE LA COSTA DE LA PROVINCIA DE RÍO NEGRO (PATAGONIA ARGENTINA): LITHIC ARTIFACTS FROM STRATIGRAPHIC DEPOSITS OF THE RÍO NEGRO PROVINCE COAST (PATAGONIA ARGENTINA)
Authors: Alberti Jimena
Published: July 2023

La costa del golfo San Matías (Patagonia, Argentina) posee una gran cantidad de materiales arqueológicos en estratigrafía, localizados en concheros de variada potencia y en depósitos enterrados. En este trabajo se presenta por primera vez un análisis preliminar de los instrumentos líticos recuperados en estos sitios. Los resultados indican diferencias entre ambos sectores de la costa rionegrina: mientras que en el sector oeste se observa una predominancia de instrumentos que habrían sido destinados al procesamiento de recursos terrestres en los momentos tardíos de la ocupación, en la costa norte los denticulados, instrumentos que habrían sido utilizados para procesar recursos acuáticos, aparecen en segundo lugar de importancia. Esto se encuentra en concordancia con el registro faunístico del área y sustentaría el modelo de consumo de recursos previamente propuesto. El estudio de las materias primas indica una explotación local para la costa oeste, con una mayor diversidad de tipos utilizados y una búsqueda de rocas hacia el interior del continente, y el uso local y alóctono para la costa norte, con un transporte de materia prima en sentido sur-norte y oeste-este y una menor variabilidad en las rocas utilizadas.

Se concluye sobre las oportunidades y desafíos para mejorar las interacciones sociales y el apoyo pedagógico en la educación remota.
PROTECTION OF WEDLOCK CHILDREN FROM THE PERSPECTIVE OF MAQASID AL-SHARI’A
Authors: Mohd Shukri Nor Najihah
Published: July 2023

This study examines the protection of children out of wedlock who do not get enough attention and are neglected in the perspective of maqashid sharia. The status of children out of wedlock generally do not get proper services because their presence is not expected. From that, the Orphan Care Agency in Sungai Petani, Kedah, Malaysia established a baby hatch that was used as a temporary shelter for these children, to be later adopted by foster parents. This article raises the problem of how the existence of the baby hatch is in the review of maqashid sharia for fear of being misused to accommodate children out of wedlock? Which problem should be prioritized in the context of the paradox between preserving the soul (ḥifẓal-nafs) and maintaining offspring (al-nasl) by looking at the existence of a baby hatch that accommodates children out of wedlock. By using the tarjih maslahat method based on data obtained from the field, this article concludes, that in this case, hifẓal-nafs should take precedence over hifẓal-nasl.

MARRIAGE EQUALITY
Authors: Hafizah Syaimanur
Published: July 2023

Marriage equality is a supporting goal (maqaṣid al-tābi'ah) that strengthens the marriage goals. This article compares the opinions of Imam Syihabuddin al-Qarafi and Ibn Qayyim al-Jauziyyah regarding equality (kafā'ah) in marriage and the methods used by both of them. The primary legal material in this legal normative research is jurisprudence. This article found that by using the textual reasoning method (al-lughawiyyah), al-Qarafi determined five aspects of equality, namely religion (al-dīn), independence (ḥurriyah), descent (nasb), not physically disabled (kamāl al-khilqah), and property (māl). On the other hand, using the method of causation reasoning (ta'līlīyyah), Ibn Qayyim al-Jauziyyah determined only one aspect of marriage equality, the religious aspect. This study concludes that al-Qarafi and Ibn Qayyim tend to depart from the thoughts of the schools they follow..

Authors: TÜRE Nurullah , KURTOĞLU Yasemin , VAROL Mehmet
Published: July 2023

Introduction: Otolaryngologists are required to possess the knowledge, skills, and confidence necessary to manage consultations requested by palliative care services. However, the inclusion of palliative care needs in otolaryngology residency training is limited. The goal of this study was to enhance awareness of otolaryngologists' palliative care knowledge and skills by evaluating otolaryngology consultations requested by tertiary palliative care services between 2016 and 2021.

Methods: This retrospective cross-sectional study included patients who consulted the otolaryngology department from the palliative care service of Kutahya Health Sciences University between January 1, 2016 and September 31, 2021. A total of 80 otolaryngology consultations were requested between 2016 and 2021. Patients were evaluated for age, gender, diagnosis of palliative admission, reason for consultation, date of consultation, interventions, and additional investigations.

Results: There were 27 female patients (33.7%) and 53 male patients (66.2%). The mean age was 65.0 (range: 22-97) years. It was found that the volume of consultations did not increase significantly over a five-year period (p=0.502) and 78.8 % of consultations were requested during working hours (08:00-16:00). In addition, the response time (minutes) for consultations during working hours (08:00-16:00) was significantly lower than outside working hours (16:01-07:59) (p<0.001). The reasons for requesting a consultation and the procedures performed were significantly different between patients under and over 65 years of age (p=0.019 and p=0.008, respectively).

Conclusions: This is the first study to evaluate otolaryngology consultations requested by a tertiary palliative care service. Awareness of these consultations may provide guidance for the assessment and management of patients in palliative care services.

A Study on the Introduction of AI Robot Tax
Authors:   Wonkwang University Legal Research Institute has, YOON HYUN SEOK
Published: July 2023

The development of AI robots leads to a decrease in tax revenue due to a decrease in earned income due to the loss of human jobs, an increase in social security costs for unemployment benefits and retraining, and furthermore, as the income gap widens, social problems caused by income inequality are worried about As a result, continuous discussions are being made in countries around the world about the introduction of AI robot tax, and Korea is also studying with interest in what AI robot tax is. Discussion on AI robot tax should start with what AI robots are and whether they can legally be taxpayers or subject to taxation. Depending on the definition, the taxation system of AI robot tax is quite different. First of all, a robot with artificial intelligence, that is, an AI robot, refers to an intelligent robot in which AI technology is applied to the robot. AI robots have abilities similar to humans to some extent. If the AI ​​robot tax is introduced because it replaces humans, it should be reviewed whether it will become a taxpayer with the same legal status as humans. To this end, AI robots must be recognized for their legal status under civil law. However, the current civil law does not grant AI robots the same legal status as humans. Therefore, it is still premature to tax AI robots as taxpayers under the tax law, that is, to impose AI robot taxes like income tax or corporate tax. If so, if robots are treated like automated equipment in industrial settings, AI robots will be subject to taxation. In response, there is an objection that taxing AI robots introduced for technological innovation may undermine the country's future competitiveness in industrial development and result in a violation of tax equity between the AI ​​robot industry and other industries. Therefore, even in order to solve these problems, it is important to set clear standards when introducing AI robot taxes. For example, the problem of how to set the tax base for AI robot tax must also be resolved. In other words, it depends on whether it is based on the number of workers who are fired if it is not the loss of employment of workers due to AI robots, or whether they are simply taxed as assets. Therefore, since it is too much to apply in the current tax law, it is desirable to introduce the AI ​​robot tax based on social consensus through continuous discussion.
Streamlining operations and best practices in the restaurant industry: A catalyst for business expansion
Authors: Savellano Joy N.
Published: July 2023

This research delves into the business operations, profiles, challenges, and best practices of homegrown restaurants in Nueva Ecija, Philippines. The study used a qualitative research design, conducting interviews with restaurant owners or managers to gather data. The findings reveal that restaurants in Nueva Ecija display significant variability in aspects such as the number of branches, years of operation, and registration status. Most restaurants tend to lean towards a corporation business model, prioritize local sourcing of ingredients, and heavily utilize word-of-mouth promotion (Kaplan & Haenlein, 2010). Challenges encountered in the operational phase mainly revolve around staffing issues, budget management, and adapting to customer preferences (Perry, 2001). Successful practices involve treating personnel as family, maintaining good customer relationships, and effective financial management (Kusluvan et al., 2010; Liu & Jang, 2009). The study concludes that robust entrepreneurial qualities, technical skills, and an excellent understanding of market trends contribute significantly to the restaurants’ success. The research adds depth to the existing literature on small-scale restaurant operations and contributes insights that can aid future entrepreneurial endeavors in the food industry (Parsa et al., 2005).

THE INFLUENCE OF WORD STRESS ON EFL LEARNERS' ToT STATE
Authors: Mailawati  , Sutrisno Adi
Published: July 2023

Tip of the Tongue (ToT) is a condition that hinders the production of fluency in speech. This study aims to identify stress patterns and factors that influence the emergence of ToT states. This research used a quantitative approach with the basis of ToT analysis theory from Brown and McNeill. For collecting data, it used an experimental design with EFL students in Kampung Inggris Pare as the objects by involving total 15 participants aged from 18th to 21st years old or late teens. The results show that the language features appearing from the experiment including words (65%), first syllables (24%), last syllables (3%), and letters (6%). The first syllable shows 21% occurrences more than that of the last syllable. There is no identification of stress in the completion of ToT in terms of the appearance of the dominating first syllable. It means that stress does not affect the completion of the ToT, but the frequency of syllables. The other factors that affect ToT in EFL include the mental processes of EFL learners, the sound imitations towards direct communication, and the teacher's role in teaching pronunciation.
Nickel-Catalyzed Regioselective Hydrosilylation of Conjugated Dienes
Authors: Wu Xiaoyu , Liu Wei , Yang Liqun , Wang Yue , Liu Tianwen , Yuan Yao , Lu Yan , Zhang Zhaoguo
Published: July 2023

With the increasing demand for homoallylic silanes and allylic silanes,
the highly efficient and regioselective hydrosilylations of conjugated
dienes are urgently needed. Herein, we developed a Ni-catalyzed
regiodivergent hydrosilylation of aromatic conjugated dienes by
adjusting the temperature and ligands. Under low temperature (-30 oC),
an eternal-ligand-free system (Ni/t-BuOK) can efficiently facili-tate
the 3,4-anti-Markovnikov hydrosilylation to provide homoallylic silanes
via electrophilic activation process; under room temperature (25 oC), a
ligand-controlled system (Ni/t-BuOK/PPh3) can eventuate the
3,4-Markovnikov hydrosilylation to produce allylic silanes via
Chalk-Harrod process. Both systems are compatible with various
conjugated dienes and primary silanes in excellent yields and
regioselec-tivities.
Targeting accelerated pulmonary ageing to treat COPD induced neuropathological comorbidities.
Authors: Luca Simone De , Vlahos Ross
Published: July 2023

Chronic Obstructive Pulmonary Disease (COPD) is a major incurable health
burden, ranking as the 3rd leading cause of death worldwide, mainly
driven by cigarette smoking. COPD is characterised by persistent airway
inflammation, lung function decline, and premature aging with the
presence of pulmonary senescent cells. This review proposes that
cellular senescence, a state of stable cell cycle arrest linked to
ageing; induced by inflammation and oxidative stress in COPD, extends
beyond the lungs and impacts the systemic circulation. This “spill
over” of senescent cells contributes to brain inflammation and damage,
increasing the risk of neurological comorbidities, such as stroke,
cerebral small vessel disease, and Alzheimer’s disease. The review
explores the role of cellular senescence in COPD-associated brain
conditions and investigates the relationship between cellular senescence
and circadian rhythm in COPD. Additionally, it discusses potential
therapies, including senomorphic and senolytic treatments, as novel
strategies to halt or improve COPD progression.
Contactless and Short-Range Vital Signs Detection with Doppler Radar Millimeter-Wave (76 - 81 GHz) Sensing Firmware
Authors: Chen Pi-Yun , Lin Hsu-Yung , Zhong Zi-Heng , Pai Neng-Sheng , Li Chien-Ming , Lin Chia-Hung
Published: July 2023

Vital signs such as heart rate (HR) and respiration rate (RR) are
essential physiological parameters used to assess human health and
bodily functions. These can be measured via methods that either require
or do not require direct contact. A non-contact Doppler radar millimeter
(mm)-wave sensing firmware utilizes a 76–81 GHz (W-band)
electromagnetic wave over a short-range path to the human body. It then
processes the reflected electromagnetic wave to filter and extract human
heartbeat and breathing rhythm signals. The short-range sensor system
proposed herein eliminates the need for electrodes, electric patches,
photoelectric sensors, and conductive wires, as well as the requirement
for direct contact with the human body when measuring physiological
signals. The W-band Doppler mm-wave sensing firmware, paired with
frequency-modulated continuous wave radar, enables continuous monitoring
of HR and RR. Short-wavelength mm-waves are employed in short-range
detection to deliver highly precise measurements of physiological
signals with minimal noise interference. Consequently, experimental
tests were conducted in a laboratory setting to measure the heartbeats
and breathing rhythm signals of healthy young men. Their HR and RR were
estimated through frequency- and time-domain analyses. The experimental
results confirm the feasibility of the proposed mm-wave radar for
continuous human vital sign detection.
Three-dimensional reconstruction and visual simulation of landscape lighting based on Unity3D
Authors: Chen Zhiran , He Zijian , Han Peng
Published: July 2023

The work description of virtual reality technology is superior to static
reference pictures and videos, which can improve the predictability of
decision makers and become a powerful performance tool for urban
lighting design. The urban scene is constructed by Unity 3D, and the
intelligent lamp pole and Rhododendron landscape lawn lamp are taken as
the research objects. On the basis of maximizing the application effect
of lamps with the HTC VIVE virtual headset, the city and lamps are
digitally mapped 1:1, After applying the model material self-luminous,
setting the type of light source and the position of the light source
point, setting the transparency mixing, adding glow, and changing the
light effect, a highly restored lamp and lamp simulation model are
formed. The research results show that this method provides a convenient
research method for the three-dimensional reconstruction and visual
simulation of urban landscape lamps. It can make decision makers have a
clear understanding of the application effect, application quantity and
interval of lamps. Immersive observation experience can make the design
scheme more honest and reliable. The efficient simulation of lighting
lamps will play an important role in the dynamic development of smart
cities in the future.

Effect of Inverted Visual Velocity Profile on Vestibular Heading Perception.
Authors: Yakouma Miguel , Anson Eric , Crane Benjamin
Published: July 2023

Visual motion is ambiguous in that it can either represent object motion
or self-motion. Visual-vestibular integration is most advantageous
during self-motion. The current experiment tests the hypothesis that the
visual motion needs to have a motion profile consistent with the
inertial motion. To test this we compared the effect on heading
perception when the visual stimulus was consistent with the inertial
motion and compared this to the condition when the visual stimulus was
inverted and was thus inconsistent with inertial motion. Twenty healthy
human subjects (mean age 20 ± 3 years, 13 female) experienced 2 s of
translation which they reported as left or right. A synchronized 2 s
visual heading was offset by 0°, ±45°, ±60°, or ±75°. In randomly
interleaved trials the visual motion was consistent with the inertial
motion or inverted – it started at the peak velocity, decreased to zero
mid-stimulus, then accelerated back to the peak velocity. When the
velocity profile of the visual stimulus matched the velocity profile of
inertial motion the inertial stimulus was biased 10.0 ± 1.8° (mean ± SE)
with a 45° visual offset, 8.9 ± 1.7° with a 60° offset and 9.3° ± 2.5 ±
with a 75° offset. When the visual stimulus was inverted so it was
inconsistent with the inertial motion the respective biases were 6.5 ±
1.5°, 5.6 ± 1.7°, and 5.9 ± 2.0°. Thus, the biases with the inverted
stimulus were significantly smaller (p < 0.0001),
demonstrating that visual motion profile is consider in multisensory
integration.
Variable Stoichiometry Effects on Glacial/Interglacial Ocean Model Biogeochemical Cycles and Carbon Storage
Authors: Fillman Nathaniel , Schmittner Andreas , Kvale Karin F
Published: July 2023

Realistic model representation of ocean phytoplankton is important for
simulating nutrient cycles and the biological carbon pump, which affects
atmospheric carbon dioxide (pCO) concentrations
and, thus, climate. Until recently, most models assumed constant ratios
(or stoichiometry) of phosphorous (P), nitrogen (N), silicon (Si), and
carbon (C) in phytoplankton, despite observations indicating systematic
variations. Here, we investigate the effects of variable stoichiometry
on simulated nutrient distributions, plankton community compositions,
and the C cycle in the preindustrial (PI) and glacial oceans. Using a
biogeochemical model, a linearly increasing P:N relation to increasing
PO is implemented for ordinary phytoplankton
(P), and a nonlinearly decreasing Si:N relation to
increasing Fe is applied to diatoms (P). C:N remains
fixed. Variable P:N affects modeled community composition through
enhanced PO availability, which increases N-fixers in
the oligotrophic ocean, consistent with previous research. This
increases the NO fertilization of P,
the NO inventory, and the total plankton biomass.
Surface nutrients are not significantly altered. Conversely, variable
Si:N shifts south the Southern Ocean’s meridional surface silicate
gradient, which aligns better with observations, but depresses
P growth globally. In Last Glacial Maximum
simulations, P respond to more oligotrophic conditions
by increasing their C:P. This strengthens the biologically mediated C
storage such that dissolved organic (inorganic) C inventories increase
by 34-40 (38-50) Pg C and 0.7-1.2 Pg yr more
particulate C is exported into the interior ocean. Thus, an additional
13-14 ppm of pCO difference from PI levels
results, improving model agreement with glacial observations.
Calcifying fibrous tumor in the abdomen: A case report
Authors: Stanisic Ivana , Zivojinov Mirjana , Ilic Aleksandra , Vrekic Zeljka , Ivanov Dejan
Published: July 2023

Introduction. Calcifying fibrous tumor is a rare benign neoplasm of soft
tissue origin. The tumor is commonly found in young adults. In most cases it
is an incidental finding, because patients do not have obvious symptoms.
This tumor may appear in different anatomical locations mimicking other
stromal lesions. The diagnosis is made based on pathohistological
characteristics and an appropriate immunohistochemical profile. The
treatment is surgical, and the prognosis is good. Case Report. A 19-year-old
female patient was admitted for abdominal surgery presenting with abdominal
pain and pressure. Abdominal ultrasonography and multislice computed
tomography of the abdomen showed a tumor mass in the right hemiabdomen. The
patient underwent surgical treatment and the tumor was completely removed.
Macroscopic analysis showed that the tumor was encapsulated and had a smooth
surface. Microscopically, the tumor consisted of bundles of partially
hyalinized collagen fibers with calcifications in the form of psammoma
bodies that were permeated with mononuclear inflammatory infiltrates.
Conclusion. Given the higher incidence of other mesenchymal tumors in the
abdomen, due to its rare occurrence, calcifying fibrous tumor presents a
diagnostic challenge.
Medical terminology in modern Serbia - more than one and a half century long journey (1841-1872-2022)
Authors: Jelenkovic Ankica , Babic Rade
Published: July 2023

Introduction. Linguistic expressions in a certain country, used in new or
less developed sciences and professions, are commonly associated with
difficulties due to the mother-tongue poverty. This also applies to the
medical terminology. In modern Serbia, despite an eight-century-long
hospital tradition, an institutional approach to the medical terminology was
first established 180 years ago by the Society of Serbian Letters, founded
in 1841, lasting until 1885. It was continued 30 years later by the Serbian
Medical Society, founded in 1872. Society of Serbian Letters. The work of
the Society of Serbian Letters on the Serbian language and terminology was
very short, because Vuk Karadzic, among others, pointed out that the Society
had to provide accurate and reliable terminology, which was not possible at
the time. The work of Dr. Jovan Stejic and his translations of the books
Macrobiotics and Anthropology are significant for medical terminology.
Serbian Medical Society. Precisely set goals related to medical terminology
and the preservation of the Serbian language in medicine were an integral
part of the first Constitution of the Serbian Medical Society. However,
during the continuous, 150-year-long work of the Society and the beginning
of medical terminology standardization, for reasons still not explored,
medical terminology has disappeared from its highest legal act, including
the current Statute. Conclusion. Not even 180 years since the first
short-term and 150 years since the long-term process of institutional
approach to medical terminology was enough to develop and standardize
medical terminology in modern Serbia. In order not to leave it to the
arbitrariness of individuals, medical terminology must be a national
strategy, such as, for example, the terminology of 33 professions in the
Republic of Croatia called Croatian Professional Nomenclature.
Application of cross-spectral analysis and fast Fourier transform to detect soil vibrations in the natural and technical geosystem of the Dniester PSPP
Authors:   Yuriy Fedkovych Chernivtsi National University, Zyhar Andrii
Published: July 2023

The main purpose of the study is to identify the relationship between changes in water level and soil deformation, where the cyclic change in loads on the reservoir bed is the stress deviator, i.e., the PSPP reservoir acts as an oscillator of transverse vibrations, and the soil extensometer performs the function of reading and recording these vibrations. Methodology. Solution of the problem requires recording the time series of water level fluctuations and extensometer sensor fluctuations on all depth horizons. It is also necessary to perform a fast Fourier transform for water level fluctuations separately and similarly to each extensometer sensor fluctuation. We need to separately calculate the signal power spectrum of all sensors in the soil, and compare the amplitude-frequency, phase-frequency components of the power spectra of water level oscillations and vertical oscillations of the extensometer sensors. Results. During the studies, it was found that the PSPP reservoir is a source of low-frequency vibrations in a wide spectral range. These vibrations have a very long wavelength, measured in tens of thousands of kilometers, which can propagate over long distances, both along the front of geological layers and in depth. Scientific innovation. The research in this article allows us to more accurately assess the frequency spectrum of vibrations and identify possible resonance phenomena that may occur in soils during the operation of a power facility. In addition, this study was conducted in a specific region, which makes it possible to obtain more accurate data on the impact of low-frequency vibrations on the geosystem in this region. Thus, this paper may be of interest to specialists in the field of geotechnics, geology, and energy. It can also be used in the planning and operation of other power facilities in similar conditions. Practical significance. Low-frequency waves can be detected by seismic instruments such as seismometers. The results of this study will help to correct the analysis and interpretation of seismograms, which is important for understanding the processes occurring in the hydroelectric power plant operation area.

This work aims to develop a method for determining the increase in stresses above an advancing longwall face of Western Donbas mines. The paper presents a solution to the problem. It is based on the analysis of geodetic instrumental observations of the earth's surface lowering and rock mass deformation above the advancing longwall face. Length and propagation in the roof and floor of the extracted seam are the main geometrical parameters of the zone of high rock pressure. Currently, the quantitative parameters of this zone are not considered. And its length under the conditions of Western Donbas is determined with an accuracy of 50%. Thus, research in this direction is relevant. The experimental basis for the research includes the results of observations performed at two vertical borehole extensometers and the results of data processing obtained at more than 30 observation stations on the Earth's surface. Thus, the research specified the geometrical parameters of the zone of high rock pressure and the nature of the vertical stress distribution within this zone. The paper introduces a method to determine a coefficient of stress increase above the advancing longwall face of Western Donbas mines. We also established the empirical coefficients of the vertical stress distribution function within the abutment pressure zone. There is a relationship between the lowering of the earth's surface and the values of the stress increase in the borehole edge part. The reliability of the obtained results is confirmed by geophysical studies in Western Donbas, as well as by the results of field observations.

The most important and promising direction in the Russian oil and gas industry is the development of the Arctic shelf, the largest in the world. Today, in the case of the development of oil and gas deposits remote from the coast, the use of underwater pipelines is not only unprofitable, but also technically unfeasible due to the short summer navigation. A problem arises when mastering the delivery of energy carriers to the industrial regions of Russia, as well as for export. One of the ways to solve this problem is the use of underwater reservoirs as a means of temporary accumulation of the product. During the operation of underwater oil storage facilities, situations may arise that lead to dome deformation. To prevent such negative consequences, a reliable prediction of the stress-strain state is required. In this paper, the authors considered the modeling of the stress-strain state of the welded joint of the wall-to-bottom of the tank, as well as the zone of monolithic steel dome of the body in concrete. The depth of 100 m for the installation of an underwater storage was chosen due to the presence of hummocks in the seas of the Russian Arctic, which can affect the seabed to a depth of 15–40 m, as well as icebergs — up to 80 m. The authors developed a numerical axisymmetric finite element model of an underwater storage section, which allows to determine the stress distribution in the domed part of the tank, as well as in the foundation, in accordance with all the features of the underwater tank. The calculations showed that for the considered operating conditions of the deposits, the use of sheets of high-strength steel D690W with a thickness of 50 mm is not enough to ensure the stability of the structure, since stresses arise in the weld that exceed the yield strength of the selected steel. Therefore, it is required either to reduce the immersion depth of the storage, or to provide for a greater thickness of the domed part of the body with the use of ribs that increase the rigidity and stability of the structure.
