Objective.
To identify risk factors for fatal outcome and COVID-19-associated liver damage in hospitalized adult patients with coronavirus infection.

Materials and Methods.
In a retrospective cohort study, 389 cases of patients with coronavirus infection complicated by bilateral viral pneumonia were studied. Demographic characteristics, clinical features of the course of the disease, anamnestic data, results of laboratory and instrumental methods of examination were analyzed and correlated with mortality. At the time of admission, the following were taken into account: fever, severity of the patient’s condition according to COVID-19 classification of severity, body mass index (BMI), oxygen saturation (SpO2), percentage of lung tissue damage according to computed tomography (CT). Laboratory indices of biochemical blood analysis were assessed in dynamics: alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, total protein, albumin, C-reactive protein (CRP). Data analysis was performed using the R programming language (ver. 4.1.1.).

Results.
The following risk factors, assessed at the time of hospitalization, increased the likelihood of death: severe and extremely severe condition of the patient (RR = 4.77; 95% CI: 3.33–6.83); SpO2 less than 93% (RR = 3.76; 95% CI: 2.57–5.49); diabetes mellitus (RR = 2.94; 95% CI: 2.01–4.30); lung tissue damage CT-3 and CT-4 (RR = 2.66; 95% CI: 1.79–3.75); concomitant chronic pyelonephritis and chronic kidney disease (CKD) (RR = 2.59; 95% CI: 1.79–3.74); age 65 years and older (RR = 2.50; 95% CI: 1.70–3.67); ischemic heart disease (IHD) (RR = 2.39; 95% CI: 1.42–4.01); an increase in the level of CRP more than 15 mg/l (RR = 2.22; 95% CI: 1.16–4.24); BMI 35 kg/m2 or more (RR = 1.89; 95% CI: 1.28–2.77); AST level more than 2 upper limit of normal (ULN) (RR = 1.75; 95% CI: 1.20–2.55). Risk factors for an increase in AST more than 2 ULN were: SpO2 less than 93% (RR = 1.53; 95% CI: 1.15– 2.03), severe and extremely severe course of coronavirus infection (RR = 1.83; 95% CI: 1.38–2.43), concomitant chronic liver disease (RR = 1.45, 95% CI: 1.08–1.95).

Conclusions.
Risk factors for fatal COVID-19 in hospitalized patients are: severe and extremely severe initial condition of the patient, oxygen saturation less than 93%, lung tissue damage more than 50%, age older than 65 years, presence of concomitant diabetes mellitus, chronic pyelonephritis and CHD, CHD, obesity, increased CRP level more than 15 mg/l, and AST more than 70 units/l. Elevation of AST over 2 IU/L can be considered as one of the prognostic laboratory markers of adverse prognosis COVID-19.

An approach to the formation of single-sideband modulation signals based on quadrature synthesis is considered. The relevance of the use of single-sideband modulation signals for decameter radio communication systems is demonstrated. The analytical generality of the signals of amplitude and single-sideband modulation is shown in the transition to the analytical form of their representation. An analysis of the known methods for generating signals of single-sideband modulation with a suppressed carrier has been carried out. Their advantages and disadvantages are shown. The structural commonality of amplitude modulation signals and single-sideband modulation signals with a preserved carrier wave is demonstrated. The introduction of an additional parameter is justified, which makes it possible to adjust the level of the stored pilot signal in single-sideband modulation signals. The developed analytical model of the single-sideband modulation signal is presented, in which, unlike the known models, the pilot signal level can be adjusted at the stage of its formation. The results obtained open up new possibilities for redistributing the output power between the pilot signal and sideband information components depending on the level of interference in the channel. It is shown that the developed approach based on quadrature synthesis makes it possible to form single-sideband modulation signals with a stored pilot signal without additional filtering procedures. The gain in noise immunity of reception during the transition from amplitude modulation to single-sideband is demonstrated. A block diagram of the formation of single-sideband modulation signals with a given pilot signal level has been developed. The results of analytical modeling are demonstrated.

Population aging and immigration: Evidence from Japan
Authors: Oliver Mikiko
Published: May 2023

In Japan, the population of immigrants has been increasing sharply, while the population is aging rapidly. Therefore, Japan is chosen for a case study to examine the relationship between demographic change and immigration. Immigration is important to the growth of the labor force due to population aging and the decline in working age population. Existing studies generally support the hypothesis that a positive association exists between population aging and immigration, which is as aging population increases, the number of immigrants increases in industrialized countries. However, there remain uncertainties as to what age range of the population is considered to increase in the proportion of older people related to the positive association, and how population composition by age group is related to the immigration in Japan. This study examines how the population composition by age group is related to immigration in Japan by applying econometric methods for the period 1975 – 2019. The results indicate that a decrease in the ratio of the population aged 60 – 64 to the total population and an increase in the population aged 65 and over are associated with increases in the ratio of foreign resident population to the total population of Japanese nationals.

Published: May 2023

Social media basically has a big influence on the dimensions of human life, because humans in their various activities cannot be separated from the existence of social media. Social media will have a good impact, if people understand and use it wisely, but it will have a bad impact if they don't use it wisely. This research principally aims to understand how Hindu teachings are to be wise and critical in managing information on social media, bearing in mind that there are two types of knowledge in Hinduism namely Paravidya and Aparavidya. The method used in this study is a qualitative method with a critical discourse analysis approach. The results of this study indicate that Paravidya and Aparavidya knowledge is the main basis that must be understood by Hindus in relation to managing information on social media. By having these two knowledges, humans can have a balance between worldly and spiritual life. In addition, the teachings of Paravidya and Aparavidya are used as a basis for analyzing further information in the process of pratyaksa pramana (namely by direct observation using the five senses), anumana pramana understands the phenomena that occur by examining them through the causal process, then upamana pramana namely through doing the process of comparison or comparison, and pramana's words, namely through instructions from people who have authority about this information. By understanding this, Hindus will be wise in controlling the information they obtain on social media.
Colloquial writing and its problems
Authors:   Korean Association for Literacy, Yi Sugon
Published: May 2023

Student writings generally lack refinement. Lengthy and unstructured writing makes the information less coherent. It appears as speech in written form. Such writing is difficult to comprehend. The text should be “more designed, selected, and organized.”
This study defined the problem of student writing as “the written language of spoken language.'” It was delineated as an “expression of psychology unrelated to the subject,” “unnecessary repetition of the same word,” and “strengthening of friendly functions rather than delivery of information.” Finally, it explained writing as an “instructional expression.”
This study found that a meticulous rhetorical strategy could increase readability and persuasion. Along with that, writing education needs to be conducted in this direction. Follow-up research will discuss specific educational measures.

Authors:   Korean Association for Literacy, Yang Ji-Seon
Published: May 2023

The purpose of this study is to shed light on the status and artistic identity of gisaengs in the process of dismantling modern Gyobang. Gyobang was established before King Gwangjong of the Goryeo Dynasty and existed until 1910, passing through the Joseon Dynasty. Rather than analyzing the meaning of the dismantling of Gyobang, which has lasted for more than a thousand years, it is being studied by focusing only on the personal activities of modern gisaengs.
Gyobang is an organization planned by the state, and modern parasitic organizations were operated in the private or private sector. The dissolution of Gyobang means the loss of the national music institution and the disappearance of the official status. After the dissolution of Gyobang, popular art due to commercial capital became a trend. Nevertheless, modern gisaeng accumulated artistic capabilities through various activities. Therefore, we would like to study the status of gisaengs and the identity of artistic activities that have changed since the dissolution of Gyobang.

La Prosa Política de Gabriela Mistral como Literatura Contra-hegemónica
Authors: Farías Rojas Gabriel Arturo , Farias Reis Páscoa Márcio Leonel , Cid Uribe Miriam Elizabeth
Published: May 2023

En el contexto del reconocimiento de Gabriela Mistral como la primer Premio Nobel de Literatura en América Latina, aún existe falta de reconocimiento de su obra literaria. Esto puede parecer extraño, y hasta increíble, pero de todas formas ocurre debido a que sólo parte de su obra, esto es su obra poética, es considerada y respetada por la crítica literaria. La segunda, su prosa, sólo es aceptada en la medida en que ella es similar a una prosa poética.  En esta situación, su prosa política, que es mayoritaria dentro de la obra en prosa por ella escrita sólo es reconocida en el mundo del silencio. Sin embargo, esa censura es contradictoria según el hecho por el cual la autora recibió el Premio Nobel de Literatura. Así, aunque hayan personas en el mundo literario que puedan esconder la naturaleza canónica de la prosa política, ella siempre va a emerger en las discusiones contemporáneas sobre la importancia de la subjetividad mistraliana, la cual, a pesar de los esfuerzos de algunos por esconder ese canon literario, conferirá a su prosa, y especialmente a su prosa política, el carácter de literatura contra-hegemónica.

Published: May 2023

The oral flora contains about 50 billion bacteria spread throughout more than 500 different species and more than 20 unique genera that coexist inside the oral ecosystem. The objective of this research is to identify the microbiological profile of the oral cavity related to dental caries and to examine their antibiogram profile. To this aim, the samples were taken from entire teeth decay, gingival, subgingival, and buccal cavity, in individuals from Medea in Algeria with age intervals between 7 and 62 years. The isolates' antibiotic sensitivity pattern was also examined. Isolates were identified using morphological, cultural, and biochemical features. This enabled us to discover 25 oral microbial strains that can become pathogenic by producing dental caries. Streptococcus spp., Lactobacillus spp., Enterococcus spp., Candida albicans, and Staphylococcus aureus were found to be the most frequent strains in the oral cavity, with prevalence rates of 32, 24, 20, 16, and 8%, respectively. The results also revealed that the prevalence of cariogenic germs depends on the range of age, among the three group ages studied we found that dental caries was high in children where the age group is 7 to 14 years. The results of antibiotic susceptibility have shown that most of the strains are sensitive to antibiotics tested, except Streptococcus spp., and S. aureus was resistant to certain antibiotics. This study indicates that some bacteria are resistant to antibiotics, implying that there is no completely efficient treatment for oral diseases and that prevention is the best approach to combat oral infections.

We investigate the extreme X-ray variability of a z = 1.608 active galactic nucleus in the 7 Ms Chandra Deep Field-South (XID 403), which showed two significant X-ray brightening events. In the first event, XID 403 brightened by a factor of >2.5 in ≲6.1 rest-frame days in the observed-frame 0.5–5 keV band. The event lasted for ≈5.0–7.3 days, and then XID 403 dimmed by a factor of >6.0 in ≲6.1 days. After ≈1.1–2.5 yr in the rest frame (including long observational gaps), it brightened again, with the 0.5–5 keV flux increasing by a factor of >12.6. The second event lasted over 251 days, and the source remained bright until the end of the 7 Ms exposure. The spectrum is a steep power law (photon index Γ = 2.8 ± 0.3) without obscuration during the second outburst, and the rest-frame 2–10 keV luminosity reaches

; there is no significant spectral evolution within this epoch. The infrared-to-UV spectral energy distribution of XID 403 is dominated by the host galaxy. There is no significant optical/UV variability and R-band (rest-frame ≈2500 Å) brightening contemporaneous with the X-ray brightening. The extreme X-ray variability is likely due to two X-ray unveiling events, where the line of sight to the corona is no longer shielded by high-density gas clumps in a small-scale dust-free absorber. XID 403 is probably a high-redshift analog of local narrow-line Seyfert 1 galaxies, and the X-ray absorber is a powerful accretion disk wind. On the other hand, we cannot exclude the possibility that XID 403 is an unusual candidate for tidal disruption events.

Sample. This sample spectroscopically selects galaxies from the Sloan Digital Sky Survey that have stopped their primary epoch of star formation within the past ∼500 Myr. Visual classifications are performed on Hyper Suprime-Cam imaging. We compare to a control sample of mass- and redshift-matched star-forming and quiescent galaxies from the Large Early Galaxy Census and find that post-starburst galaxies are more likely to be classified as disturbed than either category. This corresponds to a factor of

times the disturbance rate of star-forming galaxies. Assuming tidal features persist for ≲500 Myr, this suggests merging is coincident with quenching in a significant fraction of these post-starbursts. Galaxies with tidal disturbances are younger on average than undisturbed post-starburst galaxies in our sample, suggesting tidal features from a major merger may have faded over time. This may be exacerbated by the fact that, on average, the undisturbed subset is fainter, rendering low-surface-brightness tidal features harder to identify. However, the presence of 10 young (≲150 Myr since quenching) undisturbed galaxies suggests that major mergers are not the only fast physical mechanism that shut down the primary epoch of star formation in massive galaxies at intermediate redshift.

The cross sections of state-selective charge exchange (CX) between highly charged ions and neutrals are important for modeling extreme ultraviolet and soft X-ray emissions in many astrophysical objects with hot plasma impacting cold media. By using cold-target recoil-ion momentum spectroscopy, we measure O6+ CX collisions with He and H2 in the collision energy range of 19.5 to 100 keV amu−1. The relative cross sections of state-selective single CX are reported for electron capture into O5+(1s

With the collision energy increasing to 100 keV amu−1, the main capture channel shifts to higher n for both target species as compared to available theoretical results. We also report state-selective cross sections for double CX with He, where doubly excited states of

The present results provide experimental benchmarks available for theoretical calculations.
The Use of 0.2% Chlorhexidine Gluconate Solution Compared with 10% Povidone Iodine Solution as Anti-septic in Curettage Measure in Case of Early Pregnancy Failure
Authors: Madjid Omo Abdul , Ocviyanti Dwiana , Mohammad Azmi , Adjie Seno , Harun Siti Rafiqah Fajri
Published: May 2023

Background: Before aseptic techniques were widely used, the incidence of infections from vaginal surgery was very high at around 30% to 40%. In addition to antimicrobial prophylaxis, preparation of surgical sites with povidone iodine has been widely recommended. Another surgical antiseptic is chlorhexidine gluconate, which has various clinical uses. Evidence-based research shows that chlorhexidine gluconate is safe and effective as a preoperative antiseptic. The vagina has a mucosal structure with squamous epithelium without keratinization which has protective and secretion functions. Meanwhile the skin has a squamous epithelium with keratinization. The vagina also has several physiological conditions that have a protective effect on the vagina itself including pH conditions. Furthermore, chlorhexidine gluconate is suspected to have a pH that is almost similar to the physiological pH of the vagina.
Method: This study was a randomized clinical trial (RCT). It compared the use of chlorhexidine gluconate as an antiseptic in the action of curettage in cases of early pregnancy failure with the use of povidone iodine.
Result: The mean comfort score at 24 hours and 3 days on chlorhexidine gluconate was lower than povidone iodine but did not show a significant difference (p> 0.05), whereas on the 7th day it had the same comfort score. There was a decrease in 24 hours (0.70 vs. 0.2), the accumulation of decreases in 3 days (1.35 vs. 0.75) and 7 days (1.60 vs. 1.30) was higher in chlorhexidine gluconate compared to povidone iodine, but the difference is not statistically significant.
Conclusion: Chlorhexidine gluconate provides the same effectiveness compared to povidone iodine in curettage cases in cases of early pregnancy failure. The use of chlorhexidine gluconate can provide better comfort compared to povidone iodine in the aforementioned case, but does not differ statistically.

Internal Bleeding Management in Patient with Blunt Abdominal Trauma at Rural Hospital: A Case Report of 40-Year-Old Male with Spleen Rupture
Authors: Harjanti Erlyn Tusara Putri , Nindra Bobby , Nindra Andre
Published: May 2023

Background
Abdominal injury caused by blunt trauma is a common presentation in the emergency room.[1] Especially in developing countries like Indonesia, the number of motor vehicle accident in public roads is still high. Eighty percent of traumatic injury is blunt injury with the majority of deaths are caused by hypovolemic shock.[2]
Case description
A 43-years-old man arrived at the emergency room after motorcycle accident 2 hours before. AMPLE and primary survey was conducted: clear airway, spontaneous breathing, BP 70/palpation mmHg, HR 123 times per minutes and altered consciousness in which showed the patient was undergoing hemorrhagic shock. The patient was hemodynamically stable after given 1 liter of normal saline through two intravenous line. FAST was conducted, intraperitoneal free fluid was seen in Morison’s pouch, left hemithorax, and the pouch of Douglass. Chest X-Ray showed fracture of ribs 7, 8, 9 left lateral aspect with minimal hemothorax. After supporting examination was performed, the patient’s BP dropped to 60/40 mmHg, showed patient was a “transient responder”, indicating the patient should undergo laparotomy. The patient was given 500mL colloid with systolic target 80 – 90 mmHg in accordance to permissive hypotension theory. ±1500ml blood was found inside the abdomen during operation, a splenic rupture grade V was the cause. In the fifth day after surgery, the patient discharged.
Conclusion
Since blunt abdominal trauma could cause intraperitoneal bleeding that leads to hemorrhagic shock, therefore immediate diagnosis is needed.[1] Multiple trauma management at rural hospital should be concordant to ATLS and Schwartz’s Principles of Surgery.
Additional record of Tuponia Reuter (Heteroptera, Miridae, Phylinae) from Korea, with a new synonym and discussion on distribution
Authors: Min Suk Oh , Kim WonGun , Park Jihwan , Lee Seunghwan
Published: May 2023

The genus Tuponia Reuter, 1875 belongs to the subfamily Phylinae and comprises 91 species worldwide. Before this study, only T. koreana Kim & Jung had been recorded from the Korean Peninsula.

Two species of Tuponia Reuter, 1910 are recognised from the Korean Peninsula including the first record of T. mongolica Drapolyuk, 1980. T. koreana Kim & Jung, 2021 is proposed as a junior synonym of T. chinensis Zheng & Li, 1992. The species is identified, based on the dorsal habitus and male and female genitalic structures. A brief discussion of the distribution of Korean Tuponia species also is presented.
Duplex real-time PCR assay for the simultaneous detection of Ophiostoma novo-ulmi and Geosmithia spp. in elm wood and insect vectors

Published: May 2023

Dutch elm disease (DED) is a destructive tracheomycosis caused byOphiostoma novo-ulmi, an ascomycete probably originating in East-Asia that is devastating natural elm populations throughout Europe, North America and Asia. The fungus is mainly spread by elm bark beetles that complete their life cycle between healthy and diseased elms. Recently, it has been highlighted that some fungi of the genusGeosmithia, which are similarly well associated with bark beetles, seem to also play a role in the DED pathosystem acting as mycoparasites ofO. novo-ulmi. Although some relationship between the fungi is clear, the biological cycle ofGeosmithiaspp. within the DED cycle is still partly unclear, as is the role ofGeosmithiaspp. in association with the bark beetles. In this work, we tried to clarify these aspects by developing a qPCR duplex TaqMan assay to detect and quantify DNA of both fungi. The assay is extremely sensitive showing a limit of detection as low as 2 fg μl–1for both fungi. We collected woody samples from healthy and infected elm trees throughout the beetle life cycle. All healthy elm samples were negative for bothGeosmithiaspp. andO. novo-ulmiDNA.Geosmithiaspp. are never present in infected, but living trees, while they are present in frass of elm bark beetles (EBB –Scolytusspp.) and at each stage of the EBB life cycle in much higher quantities thanO. novo-ulmi. This work provides a better understanding of the role and interactions occurring amongst the main players of the DED pathosystem.
