Published: January 2024

Objective Emergency department (ED) triage systems are used to classify the severity and urgency of emergency patients, and Korean medical institutions use the Korean Triage and Acuity Scale (KTAS). During the COVID-19 pandemic, appropriate treatment for emergency patients was delayed due to various circumstances, such as overcrowding of EDs, lack of medical workforce resources, and increased workload on medical staff. The purpose of this study was to evaluate the accuracy of the KTAS in predicting the urgency of emergency patients during the COVID-19 pandemic. Methods This study retrospectively reviewed patients who were treated in the ED during the pandemic period from January 2020 to June 2021. Patients were divided into COVID-19–screening negative (SN) and COVID-19–screening positive (SP) groups. We compared the predictability of the KTAS for urgent patients between the two groups. Results From a total of 107,480 patients, 62,776 patients (58.4%) were included in the SN group and 44,704 (41.6%) were included in the SP group. The odds ratios for severity variables at each KTAS level revealed a more evident discriminatory power of the KTAS for severity variables in the SN group (P<0.001). The predictability of the KTAS for severity variables was higher in the SN group than in the SP group (area under the curve, P<0.001). Conclusion During the pandemic, the KTAS had low accuracy in predicting patients in critical condition in the ED. Therefore, in future pandemic periods, supplementation of the current ED triage system should be considered in order to accurately classify the severity of patients.

Objective Musculoskeletal ultrasound is increasingly used as the modality of choice in diagnosing many medical situations. The present study aimed to compare the accuracy of point-of-care ultrasonography (POCUS) and magnetic resonance imaging (MRI) to detect acute medial meniscus tears in knee. Methods The prospective study was conducted on patients with suspected medial meniscus tears in knee. in the emergency department. In the absence of a knee fracture on x-ray, POCUS on the knee was performed. All patients underwent POCUS and MRI of the knee followed by arthroscopy. POCUS findings were then compared to MRI findings to diagnose medial meniscus tears. Results A final total of 157 patients with a mean age of 25.04±7.41 years was included. Out of 157 patients, 94 (59.9%) were male. Medial meniscus tears were detected in 89 patients (56.7%) using arthroscopy as the gold standard. The sensitivity, specificity, positive and negative predictive values, and accuracy of POCUS to detect medial meniscus tears were 88.8% (95% confidence interval [CI], 80.3%–94.5%), 89.7% (95% CI, 79.9%–95.8%), 91.9% (95% CI, 84.8%–95.8%), 85.9% (95% CI, 77.2%–91.7%), and 89.2% (95% CI, 83.3%–93.6%), respectively. The diagnostic accuracy of MRI to detect medial meniscus injury was 93.0% (95% CI, 87.8%– 96.4%). Conclusion The present study demonstrated that POCUS is an accurate and reliable diagnostic tool alternative to MRI in detecting medial meniscal tears. POCUS had acceptable sensitivity, specificity, and accuracy in detecting meniscal injuries and could be performed as an effective immediate investigation to guide further modalities in patients with acute knee trauma

Objective: Effective triage of febrile patients in the emergency department is crucial during times of overcrowding to prioritize care and allocate resources, especially during pandemics. However, available triage tools often require laboratory data and lack accuracy. We aimed to develop a simple and accurate triage tool for febrile patients by modifying the quick Sequential Organ Failure Assessment (qSOFA) score.Methods: We retrospectively analyzed data from 7,303 febrile patients and created modified versions of qSOFA using factors identified through multivariable analysis. The performance of these modified qSOFAs in predicting in-hospital mortality and intensive care unit (ICU) admission was compared using the area under the receiver operating characteristic curve (AUROC).Results: Through multivariable analysis, the identified factors were age (“A” factor), male sex (“M” factor), oxygen saturation measured by pulse oximetry (SpO2; “S” factor), and lactate level (“L” factor). The AUROCs of ASqSOFA (in-hospital mortality: 0.812 [95% confidence interval, 0.789–0.835]; ICU admission: 0.794 [95% confidence interval, 0.771–0.817]) were simple and not inferior to those of other more complex models (e.g., ASMqSOFA, ASLqSOFA, and ASMLqSOFA). ASqSOFA also displayed significantly higher AUROC than other triage scales, such as the Modified Early Warning Score and Korean Triage and Acuity Scale. The optimal cutoff score of ASqSOFA for the outcome was 2, and the score for redistribution to a lower level emergency department was 0.Conclusion: We demonstrated that ASqSOFA can be employed as a simple and efficient triage tool for emergency febrile patients to aid in resource distribution during overcrowding. It also may be applicable in prehospital settings for febrile patient triage.
Inappropriate use of intravenous epinephrine leading to atrial fibrillation during prehospital anaphylaxis treatment: a case report
Authors: Jung Haewon , Ryoo Hyun Wook , Park Jungbae , Choi Seung Hyuk , Lee Jae Hyuk , Kim Sujeong
Published: January 2024

In a prehospital setting, the narrow therapeutic window of epinephrine necessitates its cautious administration to avoid anaphylaxis. In this case, a 46-year-old man presented severe anaphylactic symptoms. Following the standard protocol, the emergency medical technician (EMT) administered intramuscular epinephrine; however, symptoms persisted. Under the oversight of the emergency medical services (EMS) medical director, an additional intravenous bolus of epinephrine was administered, unfortunately leading to atrial fibrillation. This case underscores the potential risks of intravenous epinephrine, which is not typically recommended for anaphylaxis without continuous monitoring. Since 2019, Korea has initiated a pilot program to expand the EMT scope of practice, which gives them the authority to administer epinephrine for anaphylaxis. The ultimate decision regarding epinephrine use for anaphylaxis, emphasizing patient safety, rests with the EMS medical director. Proper training for EMTs, coupled with the EMS medical director’s comprehensive knowledge and meticulous protocol adherence, can ensure patient safety and optimal outcomes.
Shadow banking versus secondary shadow banking – The case of Hungary
Authors: Bethlendi András , Mérő Katalin
Published: January 2024

In this article we analyze the Hungarian shadow banking system. We point out that the Hungarian shadow banking system is not only much less developed than that of the EU's developed countries, but also structurally different. A further specific feature of the Hungarian financial system is what we call the secondary shadow banking system, through which foreign shadow banking funds do not finance the domestic banking system directly, but through foreign interbank funds and related cross currency basis swaps. The aim of our analysis is to explore the reasons for these specificities, to analyze the risks of the Hungarian shadow banking, and secondary shadow banking systems, and to show that the interconnectedness between banking and shadow banking may not only occur through direct exposure, but also indirectly through the presence of secondary shadow banking.
Morpho-syntactic structure of code-switched sentences produced by Albanian bilingual speakers
Authors: Shabani Festa , Sadiku Milote , Munishi Shkumbin
Published: January 2024

This paper aims to analyze the structure of code-switched sentences uttered by Albanian bilingual students. It examines the predictions made by two theoretical viewpoints, namely Myers-Scotton's Matrix Language Frame (MLF) and MacSwan's approach within the Minimalist Program (MP). The students were observed in informal environments within Prishtina international school settings, such as during recess time, on the playground, etc. Tape recordings of the conversations were used to record this naturalistic data, which was then transcribed. In particular, examples from the Albanian/English pair were analyzed, and the MLF and MP predictions regarding combinatorial possibilities were tested. The findings show that our data can only partially be accounted for by the MLF and MP approaches. Switching is mainly unidirectional, with insertions from English into an Albanian syntactic frame. Determiners, such as demonstrative pronouns, indefinite pronouns, adverbs of quantity, as well as copular verbs, auxiliary verbs, and clitics, come from the Matrix Language (ML), complying with the MLF model. However, violations of the MLF model are encountered as well, such as the non-occurrence of stem/affix switching, the occurrence of bare forms, and Embedded Language (EL) islands not always constituting the maximal projection of the phrase, which are further described and predicted in MP model. The paper provides evidence that neither MLF nor MP are able to adequately account for the possible combinations in the mixed clause. According to what the literature to date indicates, integrating the approaches rather than using each one individually results in a better understanding of the grammar of code-switching.
Beyond accuracy
Authors: Grose-Hodge Magdalena , Dabrowska Ewa , Divjak Dagmar
Published: January 2024

The language of Heritage Speakers (HS), or of early bilinguals of a minority language, is often seen as incomplete or less developed than that of Monolingual Speakers (MS). This study investigates whether 7- to 9-year-old English/Polish HS can be distinguished from MS in terms of linguistic skills when complexity and fluency are focal rather than accuracy. Data from 78 participants shows no significant differences between HS and MS in fluency on an overall measure in either of the languages, although HS produce more fillers and repetitions. On complexity measures, the results for English were similar across groups for Mean Length of T-Unit, but there was a statistically significant difference in Polish, with HS achieving higher values. On a more specific measure of syntactic complexity (Subordination Index), HS achieved higher scores in both languages. There were no significant differences for Lexical Diversity. Corresponding measures were positively correlated across languages, suggesting that the L1 does not impede L2 achievement. Overall, we observed substantial overlap between the groups, with the vast majority of HS falling within the MS norms and the MS falling within the HS norms. This emphasises the need to move away from the deficit approach towards HS.
Early mixing in a Spanish-English simultaneous bilingual in a Japanese context at age 2;4
Authors: Eckhaus Rebekka
Published: January 2024

Early language mixing has often been interpreted as bilinguals’ inability to separate languages, although more recent research suggests that young bilingual children have the ability in production. This study analyzes the mixing patterns of Jun, a Spanish-English simultaneous bilingual being raised in a Japanese societal context. Spontaneous speech data have been analyzed from two hours of video recordings, of four family conversations at age 2;4 [years;months], a period at which syntax should be emerging. The investigation found that Jun, prior to acquiring verb inflection, consistently speaks in the context-appropriate language and rarely engages in mixing, suggesting clear language separation and pragmatic sensitivity. Mixing rates, MLU, UB, and monoglossic production in both home languages confirm Jun's balanced performance, and also language separation. Moreover, the scarcity of inter- and intra-sentential mixing, as well as 1-word mixing, reveals the child's accommodation to his interlocutors’ language choice, as well as this 2-year-old's strong control over his own language choice

Hemodialysis is a process in which the blood is resected using a dialysis apparatus and a specific strainer known as dialyzer. Poor nutritional status is common among hemodialysis patients, but only a few studies are found on how hemodialysis is affected by other factors in the local environment. The aim of this study was to find out hemo-dialysis patients’ nutritional status and the factors that influence it. A total of 100 hemodialysis individuals (50 patients and 50 volunteers) was enrolled in this study. Anthropometry and biochemical assays, as well as nutrition assessments, were used as additional evaluation methods. According to multiple linear regression analysis, malnutrition is linked to older age, poor and lean body mass, and higher body mass index. Factors, such as interdialytic weight gain, insufficient calorie and protein consumption, and existence of morbidities, are considered along with inflammation. This study was performed at various hospitals of Sargodha district in Pakistan. Various variables of hemodialysis patients’ poor nutritional status are changeable, and these must be considered when developing and implementing effective intervention programs for this vulnerable group. Nutritional health status of hemodialysis patients was evaluated using Food Frequency Questionnaire (FFQ), concerning multiple factors, such as demographics, anthropometrics, body composition, vital signs, clinical manifestations, dietary intake, edema on the feet, triceps skin fold thickness, mild arm circumference, hand grip strength, and micronutrients. FFQs showed the overall effect of hemodialysis. Further statistical calculations and studies were conducted using SPSS, Minitab 8.1 for descriptive analysis tests for demographic features, and analysis of variance ANOVA.

Background. Food allergies (FA) are a common problem in childhood. Food anaphylaxis (FAN) can be life threatening. In this regard, it is reasonable to study clinical and anamnestic data and factors that can influence FAN formation in order to develop mathematical models of prognosis aimed at reducing acute episodes of FA, including FAN. Aims — to establish clinical and pathogenetic factors contributing to the formation of systemic manifestations of FA in children and to develop a mathematical method for predicting severe systemic reactions to food. Methods. A prospective cohort open study included 76 children (5.12 ± 3.74 years) suffering from persistent FA with a history of FAN episodes. The comparison group included 134 children (7.18 ± 2.52 years old) who had atopic diseases, local manifestations of FA, but without systemic reactions to food. Illness and life history, presence and severity of concomitant diseases were studied, general clinical and immunological studies were performed (in blood serum and oral cavity). Results. Based on the data in 210 children, the odds ratio (OR) of systemic FA formation was calculated, where the risks were: caesarean section (OR 1.8; 95% CI [1.02; 3.01]; p 0.05), immediate allergic reactions to food (OR 3.3; 95% CI [1.47; 7.39]; p 0.05), maternal anemia during pregnancy (OR 3.5; 95% CI [1.83; 6.57]; p 0.05), allergic diseases in siblings (OR 4.8; 95% CI [2.04; 11.18]; p 0.05), presence of atopic dermatitis (AD) (OR 3.7; 95% CI [1.77; 7.68]; p 0.05), allergy to cow’s milk proteins (CMP) (OR 7.8; 95% CI [4.31; 14.24]; p 0.05), clinical need for introduction of amino acid formulae (OR 100.8; 95% CI [13.37; 760.67]; p 0.05). A mathematical method was found for predicting FAN with a decision rule Y ≥ 0.35, with a forecast efficiency of up to 90% when using a linear regression equation: Y = 0.0518 + 0.2983×A1 + 0.2390 × A2 + 0.4793×A3 – 0.0037 × A4 + 0.0002 × A5, where A1 is CMP as the first allergic product (0 or 1), A2 is rapid onset of reaction (0 or 1), A3 is amino acid formulae use (0 or 1), A4 is age of wheezing (in months), A5 is eosinophils (cells/µl). Conclusions. Symptoms of AD and severe FA to CMP, requiring amino acid formulae introduction, should be considered as alarming anamnestic data for predicting possible FAN episodes, if the child has immediate type of FA, the mother’s pregnancy proceeded against the background of anemia, delivery was carried out operatively way and there are already children with atopic diseases in the family. The proposed mathematical method for predicting FAN makes it possible to determine probability of severe allergic reactions to food in children with an efficiency of up to 90%.

Published: January 2024

Background. Premature ventricular contractions (PVCs) are a common heart rhythm disorder in children, often following a benign course. However, in rare cases, antiarrhythmic therapy is required for managing this arrhythmia. Limited data is available regarding the effectiveness of such therapy specifically in children. Objective. To evaluate the efficacy and safety of propafenone administration in children with idiopathic PVCs. Methods. The study enrolled 33 children aged 11.1 ± 4.8 years (29 days — 17 years) with idiopathic PVCs. Propafenone dose was titrated from initial (5–7 mg/kg/day) to effective (no more than 15 mg/kg/day) dose under clinical and electrocardiographic control to monitor for proarrhythmias and other side effects. An increase in PQ interval duration and a widening of the QRS complex no more than 25% compared to baseline was considered acceptable. Results. The incidence of PVCs before propafenone administration was 36.3 ± 10.1 (22.0–60.6) thousands/day or 33.2 ± 8.4% (20.5–50.0). Complex forms of PVCs were observed in 25 (75.8%) children: 25 (75.8%) had frequent paired PVCs, 6 (18.2%) had polymorphic PVCs, 20 (60.6%) had short runs of ventricular tachycardia (VT), and 19 (27.6%) had a combination of various forms of PVCs. The starting dose of propafenone was 5.6 ± 2.2 mg/kg/day with subsequent increases to 10 ± 0.8 mg/kg/day. Propafenone was employed as the initial therapy in 23 (69.7%) children and as a second line therapy in 10 (30.3%) children, following the ineffectiveness or adverse effects of beta-adrenoblockers. The duration of propafenone therapy was 95.8 ± 62.8 days. Propafenone was effective in 25 (75.8%) children. The average reduction in the number of PVCs during therapy was 71.7 ± 32.6% (13.0–100.0) during therapy. One (3%) child developed proarrhythmia — sustained VT and 1 (3%) child had gastrointestinal side effects. Conclusion. Propafenone is an effective antiarrhythmic drug in children with idiopathic PVCs, including patients with poor response to beta-adrenoblockers. Arrhythmogenic and extracardiac side effects are possible during propafenone therapy, which require clinical and electrocardiographic observation in the process of selecting an effective dose of the drug.

Atopic Dermatitis vs. Eczema. History of Terminology
Authors: Potekaev Nikolay N.
Published: January 2024

Currently, one of the unresolved terminological problems of dermatology is the question of the definition of two diseases atopic dermatitis and eczema. Moreover, discussions and disputes continue between supporters of the identity of both dermatoses and adherents of their nosological independence. In our work, we have made an attempt to understand not only the definitions of the studied pathological processes, but also to compare their clinical forms in order to objectify the terminology used. It can be concluded that representatives of foreign dermatological Schools of the XIX and the first half of the XX century, using the terms "eczema", "diathesis pruritus", "neurodermatitis" and "atopic dermatitis", implied the same pathological process. While our domestic predecessors clearly defined the definitions of these two independent nosologies, denoting, respectively, unambiguous terms "eczema" and "atopic dermatitis". From the point of view of etiopathogenesis in Russia, eczema is considered as a dermatosis due to acquired hypersensitivity to external factors, while in atopic dermatitis this hypersensitivity is congenital. Domestic dermatovenerologists, based on modern ideas about the etiology and pathogenesis, genetic and immunological factors, as well as the nature of the clinical picture, use unambiguous definitions for two separate dermatological nosologies "eczema" and "atopic dermatitis", preserving the traditions of the Russian dermatovenerological School for the benefit of the development of Russian science and the health of our patients.
A Study on the Status and Challenges of Korea’s Defense Industry and Arms Trade from the Perspective of Offset Trade
Authors:   Korea Association for International Commerce and Information, Shim Sangryul , Son Wonseok
Published: January 2024

South Korea has established the base for self-reliant defense and grown into an emerging defense exporter in 40 years since it first introduced a offset trade system in 1983, and aims to become the world's fourth-largest defense exporter by 2027.
The purpose of this study is to draw implications for the development of Korea's defense industry and the expansion of defense exports from the perspective of offset trade. To this end, (1) the development process and status of Korea's defense industry were examined based on recent statistical data, and (2) the status of Korea's overseas purchase of weapons systems and defense exports were examined. Also, (3) after examining the current status of Korea's offset trade system, implications for the development of defense industry and the expansion of defense exports were drawn.
In import offset trade, it is necessary to re-apply offset trade obligation to overseas purchase through FMS from the U.S.A., settle down the banking system, expand the offset value multiplier for SMEs, and strengthen the industrial cooperation quota system. In export offset trade, it needs to establish a cooperation system between government ministries by a strong control tower, form a consortium of government-defense companies for a proactive response system, introduce a mandatory reporting system for export offset trade, expand the policy support for defense export such as trade finance, and introduce a value offset system (SWAP).

Published: January 2024

The purpose of this study is to analyze the success factors for South Korean construction companies to respond to the rapidly changing market environment and successfully enter the overseas construction market. To derive the success factors for the international expansion of South Korean construction companies, a two-step analysis technique was employed, targeting experts in the relevant field. In the first step, the Delphi method was used, involving experts in the field of overseas construction who were queried three times with repetitive questions to compress and derive important success factors. In the second step, based on the extracted final agreed-upon factors, a Hierarchical Analytical Hierarchy Process (AHP) was conducted through pairwise comparisons to validate the final priorities and the importance of factors. By setting relative importance and composite weights among the final derived evaluation indicators, the study verified the empirical importance and priorities for the efficient application of evaluation factor indicators, ultimately deriving the factors for the successful execution of overseas construction projects by construction companies.

Published: January 2024

Aim. To analyze hospitalizations and outpatient visits to primary health care facilities of patients aged 18 years and older with chronic coronary artery disease (CAD) by federal districts and the constituent entities of the Russian Federation from the perspective of the World Health Organization concept for diseases treating mainly on an outpatient basis.

Material and methods. We used data from Federal Statistical Monitoring for 2022 on the number of diseases, hospitalizations and the number of outpatient visits of patients aged 18 years and older with an established diagnosis of CAD (ICD 10:I25).

Results. In the Central, Southern and Northwestern Federal Districts, the hospitalizations and outpatient visits of the adult population with chronic CAD were higher, and in the North Caucasus, Far Eastern and Ural Federal Districts — below the Russian average level. In the Volga Federal District, the outpatient visits with chronic CAD were higher than the Russian average, and the hospitalizations were below the Russian average. In the Siberian Federal District, the outpatient visits were lower, and the hospitalizations were higher than the Russian average level. When analyzing the ratio of hospitalization rate to the number of outpatient visits of the adult population with an established chronic CAD in the primary health care unit, characterizing the availability, quality and efficiency of outpatient care, the highest indicator was recorded in the Siberian Federal District, while its heterogeneity within the federal district was the highest in comparison with other federal districts. Its lowest was recorded in the Southern Federal District, while heterogeneity within the federal district was the lowest in comparison with other federal districts. The values of this parameter varied from 3,67 in the Kurgan Oblast to 38,33 in the Republic of Tuva.

Conclusion. Accounting for diseases treating primarily on an outpatient basis can become one of the tools for assessing the quality of adult primary health care. However, before including this indicator in the criteria for assessing the quality of medical services, a deeper understanding of the reasons influencing its change is required.

Aim. To study the prevalence of hyperuricemia (HU) and gout depending on hypertension (HTN), as well as to evaluate their associations with mortality in the Russian population.

Material and methods. The analysis included data obtained in two cross-sectional studies — ESSE-RF and ESSE-RF2. All study participants were surveyed using a modular designed questionnaire. Serum uric acid (UA) was determined using the uricase method. HU corresponded to a UA >420 µmol/l in men and >360 µmol/l in women. HU without gout was considered asymptomatic HU in the present study. Associations with endpoints were assessed using Cox proportional hazards models with associated hazard ratios.

Results. The average prevalence of HU was 18,2%. HU, as expected, predominates among the male cohort — 22,6% vs 15,7%, respectively. The prevalence of asymptomatic HU was 4,4% higher among men compared to women. The prevalence of gout increased with age and averaged 2,6% in the entire population. A high content of UA was revealed in men in the absence of hypertension. The prevalence of HU in women with HTN was 3 times higher than in participants without hypertension. In the male cohort, in the group of hypertension without HU, all-cause and cardiovascular mortality significantly increases, and in the group with hypertension and HU, only all-cause mortality increases. In women, the cardiovascular death risk increased in HTN — hazard ratio 3,98 (95% confidence interval 1,86-8,52). At the same time, in women with HTN and HU, all-cause and cardiovascular death risk increased by 66% and 6,7 times, respectively.

Conclusion. Every fifth study participant was diagnosed with HU. The prevalence of HU in hypertensive men was approximately 1,5 times higher than without hypertension. In women with HTN, HU was detected three times more often than without HTN, which may indicate a more pronounced relationship between HTN and HU in women. HU can worsen the HTN prognosis. Thus, monitoring and timely correction of UA levels in hypertensive patients become necessary to improve the prognosis.

Published: January 2024

Embora a COVID-19 tenha sido inicialmente reconhecida como uma doença respiratória, tem capacidade de danificar múltiplos órgãos associados devido ao complexo processo fisiopatológico da doença e a necessidade de hospitalização prolongada nos casos graves. Apesar dos maiores desfechos prejudiciais afetarem os indivíduos que progrediram para a condição grave da COVID-19, pacientes que desenvolveram a forma moderada da doença e que não precisaram de hospitalização, também podem apresentar determinado nível de comprometimento funcional. As complicações cardiovasculares no período pós-agudo da COVID-19 são frequentemente observadas em pacientes em processo de recuperação de COVID-19. Objetivo: Verificar os impactos das sequelas pós-COVID-19, as possíveis complicações cardiovasculares e as evidências científicas da reabilitação pós COVID-19. Métodos: Trata-se de uma revisão integrativa da literatura, nas bases de dados da MEDLINE, LILACS, PubMed, SciELO, publicados entre 2020 e 2023. A amostra do estudo é composta por 15 estudos. Resultados: Os estudos demonstraram que os pacientes pós COVID-19 apresentam diferentes sequelas, algumas de modo mais frequente, não possuindo um padrão clínico; observando a abrangência multissistêmica houve um avanço no processo de reabilitação, com efeitos significativos na evolução dos quadros clínicos iniciais. Conclusão: A reabilitação pós-COVID-19 é um componente-chave para a reinserção dos indivíduos na sociedade. Considerando as manifestações multissistêmicas da condição pós-infecção, os serviços de reabilitação devem ser constituídos por equipe multiprofissional, incluindo o profissional de educação física, para atender todas as demandas dos pacientes até que restabeleça sua capacidade funcional.

The article analyzes the impact of information on education. This computerization is seen as a social phenomenon. The author refers to the origins of the formation of Social Informatics of the last century, highlighting the social significance of informatization of society as a whole. Understanding the educational space as part of the social, the author shows the influence of information as a social phenomenon on all components of the educational space, while stressing the four leading social aspects. These aspects of the conviction of the author are the following: changes in the components of the educational process under the influence of informatization; change themselves subjects of educational space under the influence of informatization; alteration of the boundaries of space and proper educational change axiological field of educational space, requiring information security measures. The article convincingly proved the lack of educational research in the analysis of social values and social aspects of informatization of educational space. Because of this kind of research is carried out in the sociology and philosophy, pedagogy open to the prospects of new research areas.

Published: January 2024

“Chronic pain after spinal surgery” (CPSS) is a nonspecific term for cases in which the end result of surgery generally does not meet the preoperative expectations of the patient and surgeon. This term has replaced the previous term i.e., failed back surgery syndrome. CPSS is challenging for both patients and doctors. Despite advancements in surgical techniques and technologies, a subset of patients continue to experience persistent or recurrent pain postoperatively. This review provides an overview of the multimodal management for CPSS, ranging from conservative management to revision surgery. Drawing on recent research and clinical experience, we aimed to offer insights into the diverse strategies available to improve the quality of life of CPSS patients.

We measured the tree transpiration of 9-year-old, Eucalyptus grandis x Eucalyptus urophylla clonal hybrid (GU) trees in the commercial forestry area of northern KwaZulu-Natal, South Africa. Transpiration was measured using the heat ratio method over two consecutive hydrological years (2019/20 and 2020/21) and up-scaled to a stand level. Leaf area index (LAI), quadratic mean diameter, and soil water content (SWC) were measured over the same period using an LAI 2200 plant canopy analyser, manual dendrometers and CS616 sensors, respectively. The depth to groundwater was estimated to be approx. 28 m, using a borehole next to our study site. Results showed that transpiration followed a seasonal pattern, with daily mean of 2.3 mm‧tree−1‧day−1 (range: 0.18 to 4.55 mm‧tree−1‧day−1) and 3.3 mm‧tree−1‧day−1 (range: 0.06 to 6.6 mm‧tree−1‧day−1) for 2019/20 and 2020/21, respectively. Annual GU transpiration was higher than that found by international studies under similar conditions, but was within the same transpiration range as Eucalyptus genotypes in the KwaMbonambi area. Plantation water productivity, calculated as a ratio of stand volume to transpiration, was higher than for other published studies, which was attributed to a very high productive potential of the study site. Multiple regression using the random forests predictive model indicated that solar radiation, SWC and air temperature highly influence transpiration. There is a high possibility that our GU tree rooting system extracted water in the unsaturated zone during the dry season. Due to the use of short-term results in this study, the impact of GU on water resources could not be quantified; however, previous long-term paired catchment studies in South Africa concluded that Eucalyptus has a negative impact on water resources. Further research is suggested with long-term measurements of transpiration and total evaporation and an isotope study to confirm the use of water by GU trees in the unsaturated zone.

In this paper, in order to optimize the recipe components, we proposed using composite mixtures in production of bread sticks, which included buckwheat, corn flour, light rye flour, vegetable powders. We studied the rheological profile of semi-finished products from composite mixtures using a farinograph. The increased content of dietary fiber in the raw materials extended the swelling time of colloids, increased the time of dough formation, but at the same time accelerated its liquefaction. However, the technological operation such as rubbing the dough was eliminated, therefore facilitating the rolling process and not requiring proofing of dough pieces; altogether, the technological process was significantly reduced. The use of light-grain rye flour “Solnyshko”, buckwheat and corn flour, vegetable powders, and black cumin oil in the recipe of bread sticks was justified. Taking into account the multifunctional properties of additives, the developed products would expand the range of products for specialized purposes.

Published: January 2024

In this paper, in order to prepare an alginate-containing gel, we used fertile two-year-old plants of Saccharina latissima (samples collected in September), which is one of the most abundant kelp seaweed in Kamchatka. We discussed the anatomical organization of samples that we used and analyzed references on the chemical composition of this species from Kamchatka. We also described stages of the disintegration process of various tissues that occur under the influence of thermo-alkaline treatment used to obtain alginate-containing gel, and also results of monitoring this process, based on the use of microscope to determine the size of pieces of algal gel and their internal state. As shown, it takes 45 minutes to prepare an alginate-containing gel without inclusion of cell aggregations of 100–200 µm in size, which are visible under a microscope.

The continuing growth of population aged 65 years and above, the socioeconomic burden of long-term care insurance has consistently increased. This study aimed to review the current system and efficiently develop long-term care insurance services according to changes in socioeconomic situations. First, a 21 items questionnaire survey was conducted from August 16 to August 31, 2022, for all members of the Korean Neurological Association. The survey was divided into seven areas, and individualized results were analyzed. Second, cumulative data on long-term care insurance services were collected and analyzed from July 1, 2008 to December 31, 2021, for the National Health Insurance system, and the results were summarized. In the survey, approximately 21% of the neurologists answered a web-based questionnaire survey on current doctors’ referral slips for long-term insurance services. Most (94%) had doctor referral slips for long-term insurance services. However, the authors estimated that doctors’ referral slips did not sufficiently affect the grading of longterm insurance services. The long-term care insurance services data according to several categories were classified and then, we statistically analyzed the socioeconomic burden of long-term insurance. Those cumulative data showed a gradual increase in the recipient number, diversity of geriatric diseases, and socioeconomic burden. We suggested that it is necessary for the government and academic society to continue to cooperate to develop the long-term care insurance systems for elderly.
