Sleep Disorders in Syria
Authors: Sahloul Mohammed Zaher , Sankari Abdul Ghani
Published: March 2023

Although there is no data on the prevalence of sleep disorders in the Syrian population, extrapolating from neighboring countries like Lebanon, Jordan, Iraq, and other Arab and Mediterranean countries, sleep disorders including sleep-disordered breathing are common. Non-Communicable diseases account for two-thirds of deaths. Hypertension, obesity, diabetes, and tobacco smoking are among the highest in the region. There is a strong association between NCDs and sleep-disordered breathing. Most sleep disorders in Syria are undiagnosed and untreated due to the absence of or very low access to sleep specialists and sleep testing, the absence of national policies, and low awareness within the medical community and among the public. The long conflict in Syria, which began in 2011, has resulted in a complex humanitarian emergency, with 6.7 million internally displaced people and 6.5 million refugees out of a total estimated population of 22.5 million. The conflict and the resultant destruction of the health infrastructure have led to a severe public health crisis, which has further impacted the health of the population. There is low access to sleep education, testing, and treatment, mostly in major urban centers, although the demands are increasing. There are ample opportunities to improve the practice of sleep medicine, in spite of the long conflict and war, if local champions, NGOs, national authorities, and medical societies adopted already-available resources, guidelines, and regulations, incorporated creative means and telehealth, and followed the recommendations of the World Health Organization on Sleep and Health.

Published: March 2023

In this chapter we describe the history, research, education, and practice of sleep medicine in Argentina, pointing out the importance of the role of public policies in the development of sleep medicine grounds. With the drawbacks of a developing or “emerging” country, sleep medicine in Argentina has been growing up in the past decades. This fact allows us to be optimistic despite the unfavorable scenarios that our country usually goes through. Sleep medicine in Argentina is still rather young in the field of medicine and needs much more effort to consolidate as a specialty.

Published: March 2023

The existence of Mentawai tattoos as a form of social cultural resistance in the islands of West Sumatra. The existence of the Mentawai tattoo culture in West Sumatra in today's increasingly modern times is a question of some circles. A strong tattoo culture of its origins was cultivated from generation to generation, is it still carried on by young people today? The tattooing process which still uses traditional techniques, tools, and materials may be one of the reasons for young people today. Young people are more interested in more modern tattoo motifs and techniques, on the other hand, since it was issued through SK No.167 / PROMOSI / 1954, which ordered the Mentawai tribe to leave their tattoo tradition and belief, Arat Sabulungan. The Mentawai people began to leave this culture and build life to follow its time. However, the tattoo culture itself has become a Mentawai identity which has been widely recognized by the Indonesian people through its origins, techniques, motifs, tools, and materials which are unique to the Mentawai people. The purpose of this study was to find information about Mentawai tattoos from their origins to the current existence of tattoos using qualitative methods. Data collection was carried out by means of a literature study. The data obtained were then analyzed and described in full. The possible results are selfacceptance, feeling equal to others, the self-concept that is built, and the vestiges of the existence of tattoos that are no longer cultured. Keywords: Existence; tattoos; mentawai culture

Published: March 2023

The Contradiction of Idea between Feminism and Anti-Feminism in Indonesia. The feminist movement has spread widely enough in various countries and continents to demand equality and women's rights. Also over time the flow of feminism began to vary with various kinds. However, there are groups who reject its existence because it is contrary to religious teachings, namely the anti-feminism movement which recently stood for its reaction to the presence of feminism. Their refusal is not without being based on their disapproval of the idea of feminism which is considered unconventional and violates the natural rules of men and women. On the other hand, feminism also stands up to violate religious rules and institutions, thereby increasing the tendency between the two. This study will look at how the perspectives and backgrounds of the movements differ by using Cross Cultural Comparison to compare the two movements through literature study. The aim is to examine how it happened between the two opposing camps in seeing the women's movement. Keywords: feminism; anti-feminism; religion; patriarchy

Published: March 2023

The Paradigm of Social Change in the Ritual of Rambu Solo' Funeral in Tana Toraja. The funeral ritual of Rambu Solo' is one of the most famous cultures of Tana Toraja. This ritual is carried out with a lively impression because they see the social strata of the deceased so that they need to show that they are indeed from an upper class or respectable society. The Rambu Solo ritual is full of meaning and cultural values (aluk) that bind the people of Tana Toraja. Thus, Aluk is divine and all creatures should be subject to Aluk. However, now the Rambu Solo' ceremony has undergone various changes in its ritual context which resulted in a change in meaning. This study examines as well as describes the socio-cultural changes that occur at the Rambu Solo' funeral ceremony in Tana Toraja. This study uses a qualitative descriptive research approach with netnographic methods and literature studies on books, scientific journals, and online news. The results showed that the 'Rambu Solo' ceremony which was used in Aluk Todolo had undergone changes because it was adapted to Christianity and modern developments.

Authors: Riyadi Andrian , Sudiyatno Sudiyatno
Published: March 2023

The current Covid-19 pandemic forces the learning process to be carried out online or long distance to impact every factor that supports smooth learning, one of which is student learning motivation. Thus, this study aims to determine the impact of online learning on vocational school students' learning motivation. The method used in this study is a qualitative descriptive research method. The research approach used is a literature study by collecting data from the results of research that has been done previously that discusses the variables related to this research. The study indicates that several factors cause a decrease in student learning motivation, including the need for more learning facilities to support student learning activities, including electronic devices and inadequate Internet networks. Boredom is also another factor that reduces students' learning motivation. In addition, changing the method of delivering learning materials to giving individual assignments is a burden for students. The role of the teacher as a motivator and mentor for students in learning could be more optimal, which also causes a decrease in student learning motivation. Parents who are busy and need more time to pay attention to their children's learning conditions also reduce students' learning motivation.

Authors: van Barneveld Esther , Lim Arianne , van Hanegem Nehalennia , van Osch Frits , Vork Lisa , Kruimel Joanna , Bongers Marlies , Leue Carsten
Published: March 2023

BACKGROUND

The experience sampling method (ESM) holds advantages over traditional retrospective questionnaires including a high ecological validity, no recall bias, the ability to assess fluctuation of symptoms, and the ability to analyze the temporal relationship between variables.

OBJECTIVE

This study aimed to evaluate the psychometric properties of an endometriosis-specific ESM tool.

METHODS

This is a short-term follow-up prospective study, including patients with premenopausal endometriosis aged ≥18 years who reported dysmenorrhea, chronic pelvic pain, or dyspareunia between December 2019 and November 2020. An ESM-based questionnaire was sent out by a smartphone application 10 times a day during 1 week on randomly chosen moments. Additionally, patients completed questionnaires concerning demographics, end-of-day pain scores, and end-of-week symptom scores. The psychometric evaluation included compliance, concurrent validity, and internal consistency.

RESULTS

Twenty-eight patients with endometriosis completed the study. Compliance for answering the ESM questions was as high as 52%. End-of-week pain scores were higher than ESM mean scores and showed peak reporting. ESM scores showed strong concurrent validity when compared with symptoms scored by the Gastrointestinal Symptom Rating Scale–Irritable Bowel Syndrome, 7-item Generalized Anxiety Disorders Scale, 9-question Patient Health Questionnaire, and the majority of questions of the 30-item Endometriosis Health Profile. Cronbach α coefficients demonstrated a good internal consistency for abdominal symptoms, general somatic symptoms, and positive affect, and an excellent internal consistency for negative affect.

CONCLUSIONS

This study supports the validity and reliability of a newly developed electronic instrument for the measurement of symptoms in women with endometriosis, based on momentary assessments. This ESM patient-reported outcome measure has the advantage of providing a more detailed view on individual symptom patterns and offers the possibility for patients to have insight in their symptomatology, leading to more individualized treatment strategies that can improve the quality of life of women with endometriosis.

Using Simulation in First Year Nursing Student Curriculum to Improve Dosage Calculations
Authors: Dubs Cynthia
Published: March 2023

Patient safety is of the upmost importance specifically when related to medication administration. Nurses are responsible for safe medication administration as a primary responsibility. Nursing education programs, especially associate degree nursing programs, use high-fidelity simulation to enhance medication administration and dosage calculation. First year nursing students are expected to pass a dosage calculation exam with accuracy to assess safe medication practices. The purpose of this quasi-experimental ex post facto design study was to examine the causal relationship between the medication administration simulation and the dosage calculation test scores in first year, associate degree nursing students. First year nursing students who participated in the high-fidelity medication administration had statistically significant differences in their dosage calculation test scores and the odds of passing the dosage calculation test on the first attempt than the students who did not participate. Age and gender demographic information of the students who participated in the high-fidelity simulation did not show any statistically significant information based on their participation. The study aims to examine which education intervention is effective in improving dosage calculation test scores in first year nursing students. Implementation of high-fidelity simulation experiences can improve dosage calculation exams scores and contribute to a safer nursing workforce.
The Effects of Nanofluids on Forced Convection Heat Transfer Inside Parallel Plate Heated with Flush Mounted Discrete Heater Sources
Authors: Atmaca Ş. Ulaş , Göktepeli İlker , Ateş Ali
Published: March 2023

A numerical solution on forced convection of Al2O3-water nanofluid for different volume fractions is investigated for laminar flow through a parallel plate with flush mounted discrete heat sources. The model used for nanofluid mixture is a single-phase approach and fluid properties are considered constant with temperature. The finite difference method is used for solutions and four different volume fractions are considered varying from 0% to 4%. A fully developed laminar velocity profile is considered and the parallel plate is assumed as heated with three discrete heat sources flush mounted to the top and bottom plate with the same lengths. Uniform wall temperature boundary condition is taken for discrete heaters. Peclet numbers are in the range of 20-100. For comparison and validity of the solution the results for a classical problem, laminar flow through a parallel plate which is heated at the downstream region with constant temperature, are obtained. Results are presented in terms of bulk temperature, heat flux, and local Nusselt number. Heat transfer is enhanced with the particle volume concentration. For comparison, pure water results are also shown in the figures. At the locations where heat is applied the heat flux values decrease as the volume fraction increase and the bulk temperature values are higher for the higher volume fractions at the heated locations. As the volume fraction increases the local Nusselt number can increase up to 30% than to pure water.

Earthquake risk in Managua: a critical view
Authors: Lomnitz Cinna
Published: March 2023

Se presenta una interpretación crítica del sismo de Managua de 1972. La falla de Tiscapa de 16 km de longitud y desplazamiento transcurrente, controla el riesgo sísmico local en Managua. EI desplazamiento del basamento ocurrió en un plano vertical único que atraviesa el Lago Tiscapa con rumbo N 32° E; no existe prueba de fallamiento múltiple. Las fracturas superficiales complejas pueden explicarse en base a esfuerzos acumulados en los sedimentos, debidos en parte a la presencia del cráter de Tiscapa que obstaculiza el movimiento de la falla. Faltan antecedentes históricos precisos en cuanto a terremotos destructivos en la Falla de Tiscapa, con la excepción del sismo de 1931 (M = 5 .8). Toda la región se encuentra intensamente fracturada con fallas activas en el Holoceno; parece dudoso que existan sitios alternativos que presenten menos riesgo geológico que el que ocupa Managua en la actualidad.A continuación, se presenta un cálculo para el riesgo sísmico máximo en Managua; se estima que el daño actualizado para un futuro indefinido alcanzaría a 3.33 x 109 córdobas. La inversión necesaria para la protección sísmica de las construcciones no excedería un 30% de dicha cantidad. De ahí que la adopción inmediata de medidas apropiadas para el control del riesgo sísmico, mediante la planificación urbana y los reglamentos de construcciones, parece representar una buena estrategia inicial, no solamente en Nicaragua. sino en toda la región sísmica comprendida entre la costa del Océano Pacifico y la Fosa Media de América Central.

Authors: Padavu Shruthi , Kumar Ballamoole Krishna , Kumar Anoop , Rai Praveen
Published: March 2023

Globally, cervical cancer is the fourth most common cancer among women. After being cloned from a recurring cervical lesion in 1987, Human papillomavirus (HPV) type-45 was identified as a high-risk HPV type. It is the third most common cancer-causing HPV subtype, after HPV-16 and HPV-18. Immunogenic epitopes and structural features provide the most useful information for vaccine development. Computational algorithms provide quick, simple, trustworthy, and cost-efficient methods for predicting immunogenic epitopes. In this study, both B and T cell epitopes have been identified as potential immunogens that can elicit a response from the host system. Three potential B-cell epitopes, i.e., SIAGQYRGQCNTCCDQ, LQEIVLHLEPQNELDP, and DSTVYLPPPSVARVVS, were identified in this study. A potential epitope for E6 (ATLERTEVY) was predicted to 8 MHC-I alleles (HLA-A*30:02, HLA-B*15:01, HLA-A*01:01, HLA-A*26:01, HLA-A*32:01, HLA-B*35:01, HLA-B*58:01, HLA-A*11:01) and for L1 epitope (NVFPIFLQM) was predicted for 4 MHC-I alleles (HLA-A*30:02, HLA-A*32:01, HLA-B*53:01, HLA-B*51:01). To conclude, the epitopes identified here might potentially be useful for developing a cervical cancer vaccine against HPV-45 strains, but in vitro and in vivo trials are needed to validate their safety and efficacy.

Study on Experimental Behavior of Plastic Based Fiber as Secondary Reinforcement in Concrete Pavement
Authors: Gupta Anjali , Chandrakar Vishal
Published: March 2023

Abstract: Nowadays, the use of fibers of various materials such as polyethylene, polyester and polymer in concrete has increased extensively as reinforcement supplement material for production of high strength concrete. The incorporation of these material in concrete not only helps in improvement of desired properties of concrete but also helps in the mitigation of disposal issue of such non-biodegradable substances. Various such materials like plastics, different grades of single use polyethylene and rubber tyres cause environmental pollution which leads to environmental and health problems. Many of these can be used as supplement to reinforce the concrete such as PET and polyethylene in fibre form. In this paper the author has studied the effect of addition of mix of different proportion of polyethylene fibre (milk packet), PET (plastic bottle) and Recron 3S as replacement of fine aggregate on concrete properties such as compressive strength, flexural strength, split tensile strength, workability. The proportions of the mixtures used were based on the dry volume of cement (0%, 0.2%, 0.4% and 0.6%).
Bioaccumulation of Different Organic Micropollutants in Fishes and its Toxicological and Stress Impacts: A Review
Authors: Basu Asmita , Moulik Shuvojit , Karmakar Sayantani
Published: March 2023

Abstract: In the past three decades biological and chemical pollutants have become a serious environmental issue posing major threat to the society, industries and public sectors. Toxic contaminants are produced in most household, agricultural and industrial activities. In the past few years different advanced electrochemical oxidation technologies and low-carbon technologies are being used widely for preventing environmental pollution and remediation of the micropollutants particularly in waterbodies. In these technologies powerful oxidizing agents like hydroxyl radicals are formed electrochemically which degrade organic micropollutants till their mineralization. Fish serves as an effective bioindicator of aquatic health due to their higher trophic position in aquatic food chain and high sensitivity to pollutants. As fishes are consumed by humans globally as a major source of protein, it is also used to indicate the impact of aquatic pollution on human health. In this review we discuss the impact of micropollutants on the fish physiology and the advanced wastewater management techniques used for rapid removal of these pollutants from aquatic ecosystem. Here we discuss both advantages and disadvantages of different commonly used wastewater management techniques which would be beneficial to determine which technology would best suit one’s specific requirements without causing much harm to the environment, a step towards green and sustainable future.

Preliminary results of petroleum source rock evaluation of Mongolian Mesozoic oil shales
Authors: Erdenetsogt Bat-Orshikh
Published: March 2023

Jurassic and Cretaceous oil shale samples, collected from northern and central Mongolian basins, have been analyzed to determine their petroleum source rock potential. The contents of total organic carbon (TOC) and total sulfur, and source rock screening data were obtained by Rock-Eval pyrolysis. Cretaceous oil shales contain up to 17.4 wt.% TOC and Hydrogen Index (HI) values range from 638-957 mg HC/g TOC. Jurassic oil shale samples have similar TOC contents, ranging from 10.7 to 17.3 wt.%. HI values of Jurassic Tsagaan-Ovoo oil shale vary between 270-313 mg HC/g TOC. Average Tmax values of Cretaceous and Jurassic samples are 4370C and 4230C, respectively. This observed data indicates that both Jurassic and Cretaceous oil shales are excellent source rock. Cretaceous oil shales contain type I kerogen (highly oil prone), while Jurassic Tsagaan-Ovoo oil shale has mixed type II/III kerogen (mixed oil and gas prone). Based on Tmax and Production Index values, both Jurassic and Cretaceous oil shales are immature. Overall, the result of this study contributes organic geochemistry database of Mongolian oil shale and encourages source rock potential of both Jurassic and Cretaceous oil shale.

Baruunnaran coal deposit is located in southern Mongolia; belongs to Tavantolgoi coal zone of South Gobi Basin (Bat-Erdene, 1992). Coal seams are hosted by Middle Permian Tavantolgoi Formation which is subdivided into lower and upper member, based on lithological characteristics. Ten core samples, consisting of sandstones were collected from exploration drill holes. 

Sandstones from Middle Permian Tavantolgoi Formation in Baruunnaran coal deposit are investigated for unravel their provenance and paleoclimate conditions andtectonic settings. Detrital modes of sandstones in lower member are characterized as slightly high amount of mineral grains (quartz and feldspar) and slightly low amount of lithic fragments (litharenite, feldspathic litharenite and lithic arkose) comparing to sandstones from upper member (litharenite and lithic arkose). Provenance study of sandstones are shown signature of recycled orogens and mixed orogenic sands. Whereas, paleoclimate condition of sandstones from lower and upper members are interpreted as they were deposited in semi humid and arid environments, respectively.
Preliminary results of the solid-state C-13 NMR study of Mongolian coals: Implications for oil and gas potential and liquefaction reactivity
Authors: Erdenetsogt Bat-Orshikh , Ko Yoon-Joo , Lee Insung
Published: March 2023

Chemical structures of five coals from Mongolia were studied using solid-state C-13 NMR and oil and gas potential as well as yields of liquefaction products of the coals have been predicted. Pennsylvanian ZG, Upper Permian TT and Lower-Middle Jurassic AT-5 coals might have more potential for gas due to abundant aliphatic and aromatic CH3 carbons. Lower-Middle Jurassic KH coal probably has more potential for oil because of its increased CH2 content. Lower Cretaceous SO-3 coal may have more potential for gas, but significant amount of non-hydrocarbon gases could also be generated simultaneously. The prediction of yields of liquefaction product shows that ZG, TT and AT-5 and KH coals could yield similar hydrocarbon gas, oil and residue. Cretaceous SO-3 coal is predicted to give the lowest yields of oil, hydrocarbon gas and residue compared with others. KH sample has the highest oil yield due to its high content of CH2.

The objective of the research was to summarize and analyze the existing and emerging methods of sustainability assessment for the territories of Ulaanbaatar City. The principle of target use of territories assumes determination of its possibilities for performance of social and economic functions on the basis of a preliminary assessment of its natural resources, value of natural objects, etc. It is important that the mandatory damage was minimal, and the planned benefits significantly exceeded them. A principle of safety assumes that any anthropogenic impact on the geological environment should not create environmentally harmful and dangerous to the habitat of the present generation and have long-term environmentally harmful consequences for future generations. Generalization and systematization of information about the state and stability of the geological environment should be consistent with the scale of the problems and the level of decision-making (global, regional, local). The results of assessments of the stability of territories can be presented in various forms, as well as the leading natural and man-made factors that affect their stability. They include quantitative, semi-quantitative and qualitative assessments. The cost criteria for evaluating the stability of territories are being widely developed at present in two main directions. The first is assessment of the risk of the impact of dangerous natural and natural-technogenic processes. The second is due to the assessment of the costs required for the construction and normal operation of natural-technical systems or objects, including their engineering protection.
