Authors: Sinyavsky O. , Savchenko V. , Pyentak T. , Hrusch V.
Published: December 2023

Deviations and asymmetry of the surface have the greatest impact on the electric drives of production machines and mechanisms.

Voltage asymmetry leads to losses that have an electromagnetic and technological component.

The effect of voltage asymmetry on the technological characteristics of working machines and mechanisms is manifested in a decrease in their productivity. However, there are no studies on the influence of voltage asymmetry on the energy characteristics of working machines.

The purpose of the research is to establish the influence of voltage asymmetry on the energy characteristics of nori.

Voltage asymmetry leads to a change in constant and variable losses in an asynchronous electric motor.

It is proposed to carry out an energy assessment of the electric drive of the nori according to the specific consumption of electricity.

A study of the effect of voltage asymmetry on the energy characteristics of the electric drive of the noriy was carried out. The dependence of the specific power consumption on the change in stiffness of the mechanical characteristics of the electric motor, which is caused by voltage asymmetry, is obtained. It was established that slippage and power losses in an asynchronous electric motor increase with voltage asymmetry. As a result, the specific losses of electricity in the norias increase.

Published: December 2023

When comparing the efficiency of balancing single-pipe heating systems of a building and assessing its impact on the saving of thermal energy by the building of a higher education institution (HEI), a model of the thermal regime of the building was compiled and characterized as a single thermal energy system taking into account its three subsystems: a model of the thermal energy effect of the external climate on the building (η1), models of the thermal energy influence of the thermal inertia of the building envelope (η2) and models of the thermal energy influence of the engineering systems of the building (η3). In order to assess the availability of specified indicators, based on heat energy impact models, the availability coefficient Kz(PD) (project deviation) is introduced, which shows (in fractions of a unit) the deviation of the mentioned indicators from the calculated conditions and characterizes the degree of difference between the implemented solution and the optimal one and is an indicator of heat energy efficiency project solution as a whole. The savings of thermal energy obtained when using different options of automatic balancing are presented - for a single-pipe system with a constant hydraulic mode and separately for a single-pipe heating system with a variable hydraulic mode. It was established that with an increase in the value of the internal heat capacity of the building, the decrease in the specific energy consumption of the HEI building becomes less noticeable, compared to less massive buildings (light and very light structures). Thus, for buildings with an indicator of the internal heat capacity of the building С = 110 W ·  h/(m2 ·  K), the specific rate of reduction in energy consumption by the HEI building is 0.8 thousand kWh/m², while for buildings with an indicator of the internal heat capacity of the building C = 80 W ·  h/(m2 ·  K) and C = 25 W ·  h/(m2 ·  K) - the specific reduction in energy consumption by the building was 1.0 thousand kWh/m² and 1.1 thousand kWh h./m² per year, respectively. It is shown that the level of energy savings after balancing the heating system for a building of very light construction (index of internal heat capacity of the building С = 25 W ·  h/(m2 ·  K)) was 2 %, for buildings of heavy and very heavy constructions (index of internal heat capacity of the building C = 80 W ·  h/(m2 ·  K) and C = 110 W ·  h/(m2 ·  K) respectively) – 2.2 %.

Published: December 2023

The work is devoted to the development of a system for automatic control of the process of continuous dealcoholization of wine in a vacuum thermoelectric distiller. A parameterized technological diagram of the process as a control object has been developed, the main parameters subject to regulation have been identified, namely the pressure in the receiver, the temperature of the dealcoholized wine material at the outlet of the evaporator, the temperature in the condenser, and their technological regulations have been determined. The corresponding control actions are defined: the rotation frequency of the vacuum pump, the current of the thermoelectric converter of the evaporator, the current of the thermoelectric converter of the condenser. A structural diagram of the technological process of wine dealcoholization as an object of management has been developed. On the simulation model of a vacuum distiller in the Matlab Simulink environment, experiments were conducted to study the dynamic properties of the main channels of transformations. From the received transient characteristics, the transfer functions of the control channels are determined. The synthesis of a three-dimensional system of automatic control of the temperature of the dealcoholized wine material at the outlet of the evaporator, the temperature in the condenser and the pressure in the receiver was carried out. The initial settings of the regulators were calculated, the parametric optimization of their settings was carried out, and the transient characteristics of the regulated variables under stepped input influences were obtained. The obtained systems of automatic control of the temperature of the dealcoholized wine material at the outlet of the evaporator, the temperature in the condenser and the pressure in the receiver are tested for roughness under the influence of parametric disturbances.

Published: December 2023

The paper considers the problem of estimating the price of real estate. Automation of the solution to the specified problem is one of the methods of providing an objective assessment, which excludes such subjective factors as an arithmetic calculation error, assessment under the influence of emotions, assessment under the influence of the pursuit of one's own goals. Most often, regression analysis (hedonic regression) and machine learning methods are used to solve the problem of estimating the price of real estate. The purpose of this research is to build a model for estimating the price of real estate not only on the basis of the usual quantitative indicators (for example, area, number of rooms, floor, etc.), but also on the basis of the textual description of the real estate. In this paper we consider a real estate in new residential builings in the Kyiv. To achieve the goal, a mathematical model was developed for the classification of real estate class based on a textual description using a recurrent neural network. The model is developed as a multi-layer feed-forward neural network that accepts textual data describing a new residential building and passes it through a series of hidden layers, where each layer consists of neurons. The simulated categorical variable 'predictedClass' was used as the independent variable of the linear regression to calculate the price of an apartment in a new building. Compared to classical linear regression with quantitative regressors, the new model provided a high R2 with a minimal number of variables.

The “mixture”- like composite materials consist of a matrix and a filler. An interaction between these components, i.e., the matrix and filler particles, can result in formation of the transition layers (interphases). A chemical composition, spatial and energetic structures of these interphase layers differ from those peculiar for initial components. Accordingly, the properties of such transitional layers could be significantly different from those ones for a matrix or a filler. The role of interphase layers increases when particles became nanosized and with their concentration increasing. An influence of the interphase layers on the properties of composite increases at such conditions and even could be determining. The considerations described above are a basement of the proposed method of control (engineering) of the composite materials properties. This paper reports the results of the study of the interphase layers manifestations in luminescence properties of the “glass-ceramics” type of composites, those consist of mK2O-kP2O5-nB2O3:xPb-yEu oxide glass matrix and Eu3+- doped luminescent oxide polycrystalline KCa(BO3)3compound, as a filler. A possibility of tailoring the emission wavelength of the glass-ceramics has been discussed as well. A morphology, structure and optical properties of the prepared glass-ceramics have been studied by means of scanning electron microscopy (SEM), X-ray diffraction (XRD) and photoluminescence (PL) spectroscopy, respectively. The SEM images are typical for vitreous materials when some micro/nanocrystallites of KCa(BO3)3 oxide incorporated into matrix can be seen in case of glass-ceramics. XRD patterns reveal wide bands those are peculiar to vitreous materials, while the patterns of glass-ceramics additionally contain the narrow bands related with crystalline filler. Wide-band spectra of own luminescence have been observed under photo-excitation of glassy samples. In contrast, weakening of this PL emission and a domination of a linear emission related with f-f transitions in Eu3+ ions, takes place in the case of glass-ceramics. A detailed analysis of the linear PL has been shown the presence of three types of Eu3+ ions in glass-ceramics: there are ions located in the oxide particles, glass and interphase layer. Spectral characteristics of the PL related with each of these types of ions are significantly different, that provide a possibility to control PL emission spectra by changing contribution of interphase layer to overall spectra of the glass ceramics studied.

The contemporary educational process, like all other spheres that ensure the vitality of our country, is in an extremely complex situation. This complexity arises not only from military actions but also from the transitive reality in which we all find ourselves. The specific social reality resulting from ideological, political, economic, and educational changes indicates the need for a profound analysis of what is happening today and now. It is essential to analyze not only the present but, more importantly, past historical events to prevent future dreadful conflicts such as war, genocide, and cultural destruction. The purpose of this article is to investigate and analyze the problem of freedom and security in the conditions of war. To achieve this goal, the following tasks were set: identify various research paths of the freedom and security problem, analyze these concepts, demonstrate the scope of application, use, and speculation with the concepts of freedom and security, especially during times of war. Methods. During the research, the methods of systemic-structural analysis and hermeneutics were employed. The hermeneutic method involved accumulating a substantial amount of material through the analysis of global and domestic informational, journalistic, and internet sources. This allowed for a comprehensive examination of the problem of freedom and security from different perspectives. As a result of the study, it was established that the problem of freedom and security in wartime arises in an extremely acute format. A nation experiencing war has the right to form its own criteria for choice. However, a conscious civic position needs to be shaped through educational and humanitarian programs at all levels, which will help form an independent, critical mindset, providing the ability to self-determine freely and be aware of the responsibility for decisions and actions. Conclusions. The problem of choice between freedom and security requires a deep, detailed analysis not only in contemporary conditions but also considering the post-war period of Ukraine's formation and development. After all, these problematic issues are fundamental principles of a democratic state.

Published: December 2023

In recent years, significant advances in nanotechnology have increased the ability to produce nanoparticles of physiologically important metals on a large scale, which are now used to improve fertilizer formulations to increase uptake by plant cells and minimize nutrient losses. Fertilizers with nanostructure can increase the efficiency of nutrient use through mechanisms such as targeted delivery, slow or controlled release. The aim of the research is to substantiate a compensatory scheme for the use of biodynamic nanofertilizers (nanocomplex micronutrient fertilizers with organic acids) by partially replacing the main macrofertilizers in the spring wheat fertilization system. The research was conducted on the basis of the educational and scientific laboratory Department of Plant Industry of the National University of Life and Environmental Sciences of Ukraine. In research, there were used the methods of field experiments of A.O. Rozhkov, notching method and scanning method for determination of leaf surface area. The studies showed that it is possible to replace within 30-40% of the recommended amount of mineral fertilizers with biodynamic nanofertilizers in the spring wheat fertilization system. In general, the use of nanofertilizers increased wheat growth and improved yield and yield components. Substitution of mineral fertilizers, Innoparmis Agroscience Biodynamic fertilizers, provides a more favourable 86-88% survival rate of spring wheat plants during the growing season. By replacing 34% of the recommended rate of mineral fertilizers, the content of photosynthetic pigments in wheat leaves increases by 5% and the leaf surface area increases by 7%. The created compensatory schemes for the use of biodynamic nanofertilizers by partial (34% in the wheat fertilization system) replacement of the main macronutrients can increase the yield of spring wheat by 9.9%. The proven possibility of replacing mineral fertilizers with biodynamic nanofertilizers in the fertilization system of agricultural crops will reduce environmental pollution and the economic dependency of using mineral fertilizers against the background of their rapid increase in price in recent years

Published: December 2023

Hyperextension injuries of the ankylosed thoracolumbar spine, particularly those with preexisting kyphotic deformity, present significant therapeutic challenges. The authors viewed that such injuries without displacement or fractures of the posterior elements are reasonable candidates for standalone percutaneous vertebroplasty (PVP). In such cases, the posterior tension band is spared; thus, fractures are unstable not in the lateral direction, which would lead to the translation of the fracture, but in the vertical direction. Such vertical instability of the fracture can be stabilized if the open mouth-type vertebral cleft is adequately filled with a sufficiently large amount of polymethylmethacrylate (PMMA) cement. Our three patients receiving standalone PVP received injections of 12 mL, 16.5 mL, and 18 mL of PMMA cement. This minimally invasive surgical procedure achieved both short-term (immediate pain relief and mobilization) and long-term (fracture healing) goals.

Cele: 1. Porównanie percepcji zagrożeń COVID-19 i zanieczyszczeniem środowiska, gotowości do ponoszenia kosztów w celu ochrony przed tymi zagrożeniami oraz percepcji kompetencji do przeciwdziałania tym zagrożeniom. 2. Porównanie układu zależności między analizowanymi zmiennymi w kontekście obu zagrożeń między: (a) percepcją zagrożeń a gotowością ponoszenia kosztów ekonomicznych i gotowością podejmowania zachowań chroniących przed zagrożeniem; (b) percepcją zagrożeń i gotowością ponoszenia kosztów a zachowaniami; (c) zasobami psychologicznymi (aspiracje życiowe, percepowane kompetencje i strategie radzenia sobie ze stresem) a gotowością ponoszenia kosztów i zachowaniami.
Metoda: W badaniu online wzięło udział 300 osób, 50% kobiet i 50% mężczyzn, w wieku od 19 do 59 lat (M = 39,79, SD = 11). Wykorzystano w nim skale: percepcji zagrożenia COVID-19 (Cypryańska i Nezlek, 2020); gotowości ponoszenia kosztów COVID-19 (Cypryańska i Nezlek, 2020) – obie zastosowane także w kontekście zagrożenia zanieczyszczeniem środowiska; Inwentarz strategii radzenia sobie ze stresem (Addison i in., 2007); Indeks aspiracji życiowych-23 (Grouzet i in., 2005) oraz skale percepowanych kompetencji ochrony zdrowia przed COVID-19 i zmiany zachowań konsumpcyjnych (inspirowane Williams i in., 1998). Zmienne przewidywane to podejmowanie zachowań ochronnych przed COVID-19 i zachowań zmniejszających zanieczyszczenia środowiska.
Wyniki: Zagrożenie zanieczyszczeniem środowiska jest spostrzegane jako silniejsze, większa jest gotowość ponoszenia kosztów ekonomicznych i silniej są percepowane kompetencje niż w przypadku zagrożenia COVID-19. Istnieją podobieństwa i różnice w układzie zależności w modelach dla badanych zagrożeń. Istotne dla zmiany zachowań w obliczu zagrożenia są: percepcja zagrożenia dla jednostki i dla świata, wspólnotowość, percepowane kompetencje i strategie radzenia sobie ze stresem.
Konkluzja: Każde z zagrożeń ma swoją specyfikę, którą należy brać pod uwagę, poszukując predyktorów różnych aspektów funkcjonowania jednostek w jego obliczu i opracowując strategie komunikacyjne nakierowane na zmianę zachowań.

Published: December 2023

Exosomes are a subtype of natural extracellular vesicles that transfer a great number of biomolecules, released by almost all types of cells, and can be specifically taken up by recipient cells in order to maintain homeostasis and induce a proper response to stress or harsh environmental conditions. Since the heart is part of complex systems which involve various cell types, exosome-mediated communication plays a crucial role in the cardiovascular field. Given the extended studies on the molecular mechanisms mediated by exosome cargos, leading to cardiovascular diseases, we focus on the most important data that report the roles of proteins and microRNAs (miRNAs) transferred by exosomes and whether they possess cardiotoxicity or cardioprotection and also the potential of these biomolecules as therapeutic tools or diagnostic biomarkers.

Authors: Shetabi Hamidreza , Peyman Alireza
Published: December 2023

Background:Phacoemulsification is the main method of cataract surgery in developed countries. Due to the importance of appropriate analgesia and the immobility of the participants throughout the procedure, the study aimed to assess the impact of intranasal ketamine vs. intranasal fentanyl on the quality of sedation and analgesia in phacoemulsification surgery. Materials and Methods: This double-blinded study was carried out on participants who underwent cataract surgery in Faiz Hospital, Isfahan, Iran. Eighty subjects were randomly assigned to two groups of 40 receiving ketamine at a dosage of 1.5 mg/kg intranasally (Intranasal Ketamine (INK) group) or fentanyl at 1.5 μg/kg nasally (Intranasal Fentanyl (INF) group). The drugs were administered through the nasal passage 15 minutes before the operation. The primary outcomes were a difference in the quality of sedation and pain relief between groups during the procedure and recovery unit. Secondary outcomes were cardiovascular parameters, side effects, the need for sedative rescues, and changes in vital signs. Results:During the study, 25 patients (62.5%) in the INK cohort and 19 patients (47.5%) in the INF cohort had no pain. In the INK group, 22 (55%) and in the INF group 20 (50.0%) patients achieved optimal sedation (Ramsay sedation score 4). There was no discernible disparity observed between the two cohorts in terms of the quality of sedation (P=0.071), receipt of rescue dosage of propofol (P=0.601), hemodynamic parameters (P>0.05), and side effects during treatment Operation (P=0.542) and in recovery (P=0.104), patient (P=0.098) and surgeon (P=0.120) satisfaction, operative time (P=0.082), and duration of stay in recovery (P=0.110). Conclusion: Although INK was more effective than INF in reducing pain and achieving optimal sedation in cataract surgery, it was not significantly superior to INF.
Curcumin Aattenuates the Expression of Metalloprotease (AHA_0978) and Serine Protease (AHA_3857) Genes in Aeromonas Hydrophila: Curcumin on Protease Genes in A. Hydrophila
Authors: SobhZadehi Mahdieh , Zamani Hojjatollah , YektaKooshali Mohammad Hossein
Published: December 2023

Background: Aeromonas hydrophila is a pathogenic bacterium responsible for various infections in humans and animals. Bacterial exoproteases are considered an important determinant in the pathogenicity of A. hydrophila. Serine protease and metalloprotease, that are regulated by the bacterial Quorum sensing (QS) system are important virulent factors in the pathogenicity of A. hydrophila. Anti-QS potential of curcumin has been reported, previously. In this work, we characterized the effect of curcumin on the expression of the metalloprotease and serine protease genes in A. hydrophila. Materials and Methods: The minimum inhibitory concentration (MIC) of curcumin was measured by the agar macro-dilution method and a sub-inhibitory concentration (1/2 MIC) was used in subsequent experiments. The expression level of the metalloprotease and serine protease genes among the treated and control bacteria was evaluated using quantitative PCR (qPCR) assay. Bacterial proteolytic activity was also measured by skim milk agar plate assay. Results: MIC of curcumin for bacterial strain was 1024 μg/ml curcumin, and at 512 µg/mL (1/2 MIC) it remarkably attenuated the expression of the metalloprotease and serine protease genes up to 66 and 77%, respectively. Also, the proteolytic activity of A. hydrophila was considerably reduced by curcumin. Conclusion: Due to the promising inhibitory effect on bacterial proteolysis, curcumin could be considered an anti-virulence agent against A. hydrophila.

Calcifying epithelial odontogenic tumor (CEOT) and ameloblastoma are types of odontogenic tumors accounting for 1%, and 10% of all the odontogenic tumors. While sharing same odontogenic origin, these tumors are found to exhibit distinct clinicopathological features. In the present study, we present the third hybrid CEOT/Ameloblastoma tumor ever reported. The current CEOT/Amelobastoma is occurred after a previously operated CEOT in the same area. The patient was refered with distict clinical features of swelling and paresthesia. In the radiographic examination, a unilocular lesion with mixed internal structure and ambiguous periphery was seen which exhibited buccal and lingual cortical expansion, thining, and perforation as well as inferior alveolar canal perforation. The histopathology results suggested a CEOT/Ameloblastoma lesion. After the tumor removal, the patient was set up for further follow-ups and maxillofacial prosthesis.

Background: Multiple studies have investigated the serum concentrations of calcium (Ca) and magnesium (Mg) in preeclampsia, but the results have been contradictory. The objective of this systematic review and meta-analysis was to examine the association between serum calcium and magnesium levels in patients with preeclampsia and those in the healthy pregnancies. Materials and Methods: A comprehensive search was conducted in various online databases, including PubMed/Medline, Scopus, Embase, Web of Sciences, and Cochrane library to identify relevant studies on Ca and Mg levels in preeclampsia up to July 2023. Inter-study heterogeneity across the included studies was assessed using the chi-square test and I2 statistic. Pooled effect size (ES) was calculated as weighted mean differences (WMDs) with corresponding 95% confidence intervals (CI). Results: A total of 76 articles (comprising 92 studies) were included, with a combined sample size of 10,482 participants (preeclampsia: n=3,991; controls: n=6,491). The random-effects model revealed significantly lower levels of calcium (WMD=-0.807 mg/dL, 95% CI: -0.983, -0.632, P<0.01) and magnesium (WMD=-0.215, 95% CI: -0.338, -0.092, P<0.01) in women with pre-eclampsia compared to the control group. However, the overall pooled WMD for calcium and magnesium levels did not significantly change when individual studies were excluded one by one. Conclusion: This meta-analysis demonstrates that the circulating levels of calcium and magnesium in patients with preeclampsia are significantly lower than those in the control group.

To assess the frequency of hypercholesteremia in patients presenting with acute coronary syndrome. From February 1, 2020, to February 1, 2021, 100 patients who presented with acute coronary syndrome underwent a retrospective study at the cardiology department of the Hayatabad Medical Complex in Peshawar. The diagnosis, lab tests, patient outcomes, and demographic information were gathered and examined. All the data analysis was done by SPSS. According to the findings, 24.0% (or 100/100) of the patients had hypercholesterolemia. The patients with hypercholesterolemia were 58.75 + 9.39 years old on average. Patients with hypercholesterolemia had a 16.6% death rate. Patients with hypercholesterolemia had a substantially increased morbidity rate (OR = 2.937, p=0.01). In the examined population, hypercholesterolemia is a significant comorbidity linked to acute coronary syndrome, and it should be appropriately managed and treated to improve the management of acute coronary syndrome.

The aim of this study was to collect data on different haemoglobin disorders in children who presented to the pediatric clinic at HMC/IBP with pallor and microcytic hypochromic anaemia on peripheral smears. This cross-sectional retrospective study was conducted in the HMC Pediatric IBP Clinic over a period of 4 years from 2018 to 2022. The blood samples were collected from patients with anaemia. All the data was analyzed using SPSS. A total of 48 children (21.6%) were diagnosed with various hemoglobinopathies, while 29 cases (13%) were classified as "undetermined" due to being borderline or requiring repeat electrophoresis. Additionally, 35 children (15.8%) were found to have other causes of anaemia. Hemoglobinopathies are a public health issue and more so in a resource-limited country like Palristan. One of the contributing causes of anaemia in the pediatric age group is hemoglobinopathies.
Techniques for restoring optimal spinal biomechanics to alleviate symptoms in Bertolotti syndrome: illustrative case
Authors: Brown Nolan J , Pennington Zach , Shahin Hania , Nguyen Oanh T , Pham Martin H
Published: December 2023

BACKGROUND

Lumbosacral transitional vertebrae (LSTVs) are congenital anomalies that occur in the spinal segments of L5–S1. These vertebrae result from sacralization of the lowermost lumbar segment or lumbarization of the uppermost sacral segment. When the lowest lumbar vertebra fuses or forms a false joint with the sacrum (pseudoarticulation), it can cause pain and manifest clinically as Bertolotti syndrome.

OBSERVATIONS

A 36-year-old female presented with severe right-sided low-back pain. Computed tomography was unremarkable except for a right-sided Castellvi type IIA LSTV. The pain proved refractory to physical therapy and lumbar epidural spinal injections, but targeted steroid and bupivacaine injection of the pseudoarticulation led to 2 weeks of complete pain relief. She subsequently underwent minimally invasive resection of the pseudoarticulation, with immediate improvement in her low-back pain. The patient continued to be pain free at the 3-year follow-up.

LESSONS

LSTVs alter the biomechanics of the lumbosacral spine, which can lead to medically refractory mechanical pain requiring surgical intervention. Select patients with Bertolotti syndrome can benefit from operative management, including resection, fusion, or decompression of the pathologic joint.
A 64-year progression of an intradiploic epidermoid of the frontal skull: illustrative case
Authors: Ott Stefanie , Lübke Andreas , Mohme Malte , Westphal Manfred
Published: December 2023

BACKGROUND

Epidermoid cyst tumors can arise as intradiploic tumors in the frontal skull bones around the fontanel in childhood but are mostly found at the frontal or frontotemporal base of the brain or in the cerebellopontine angle. Therefore, finding a symptomatic intradiploic lesion in the convexity in late adulthood is uncommon. Intradiploic epidermoids can cause complications as they grow, by eroding and perforating their surroundings, and in cases of destruction of the wall of a pneumatized sinus, they can cause pneumocephalus.

OBSERVATIONS

In the present case, a female patient presented with a skull lesion that had grown progressively over 64 years, resulting in spontaneous pneumocephalus. Surgery with subsequent cranioplasty was performed. The histological examination confirmed the presence of an intradiploic epidermoid.

LESSONS

This case highlights that complete resection of the lesion with subsequent cranioplasty is recommended before symptoms and reconstructive challenges due to the enormous size of the defect. This case serves as a reminder that intradiploic epidermoids, although uncommon, will expand throughout life and can cause significant complications such as pneumocephalus after decades. Timely surgical interventions after diagnosis are recommended to prevent further complications and to achieve a successful outcome in terms of complete resection and reconstruction.
Terminological Databases as a Means to Access Knowledge
Authors: Heinisch Barbara
Published: December 2023

Terminological databases are a means to manage and access specialist knowledge. Since they are specialist tools, non-terminologists may face difficulties when using them. This is related to two aspects. On the one hand, the user interface of a terminological database is targeted towards terminologists who are familiar with terminology management and the terminology of terminology. On the other hand, the content of terminological databases, i.e. terminological entries containing terms of certain domains, as well as the concept orientation of terminological databases might seem daunting at first glance if the users are not familiar with the relevant domain and terminology work.Therefore, drawing from usability engineering principles, this article addresses how terminological databases can be designed in a way that allows users who are not familiar with terminology work to easily access terminological databases, and thus the knowledge contained in them. Terminological databases are often used by terminologists and non-experts in terminology alike. Therefore, the needs of these different user groups should guide the(further) development of terminological databases to make the knowledge contained in them accessible to a broad audience.
Imagining Democratic Futures: Asia and the Pacific Foresight Report 2024
Authors: Kenny Emma , Runey Michael
Published: December 2023

According to data from International IDEA’s Global State of Democracy (GSoD) Initiative, democracy in Asia and the Pacific is under significant pressure. Only a tiny minority of people in the region live in a high-performing democracy. In the face of weak parliaments and polarized electorates, judiciaries and government agencies like election management bodies have been the core institutions working against democratic decline. Democratic institutions across the region appear, in simple terms, stuck. With key elections forthcoming in 2024 in Bangladesh, India, Indonesia, Pakistan, South Korea, Taiwan and elsewhere, the question of what to do about democracy in the region is as acute as ever. To complement the GSoD data, International IDEA gathered experts and practitioners from academia, journalism, civil society and law for a two-day foresight workshop to discuss the possible coming trends and challenges, and the outcomes of that workshop form the basis for this Discussion Paper.

Kruvaziyer turizm turistlere yönelik farklı aktiviteleri bir araya getirebilen bir niteliğe sahiptir. Bu doğrultuda söz konusu turistlere yönelik sunulan hizmetler arasında ulaşımın yanında yeme-içme, konaklama ve diğer rekreasyon faaliyetlerinin de yer aldığını söylemek mümkündür. Öte yandan kruvaziyer turistler liman ziyaretleri ile birlikte limana yakın turistik yerleri ziyaret ve alışveriş imkanlarından da faydalanırlar. Bundan dolayı ülkeler söz konusu limanlara ve destinasyonlara önemli yatırımlar yapmaktadır. Bu kapsamda Türkiye’de yer alan kruvaziyer gemilerin ziyaret rotasında yer alan limanların 2017-2022 yılları arasındaki beklenen ve gerçekleşen büyüme oranlarının tespit edilip karşılaştırılması amacıyla gerçekleştirilen bu araştırma nitel desende tasarlanmıştır. Söz konusu verilere döküman analizi yöntemi ile ulaşılarak elde edilen veriler değişim pay analizlerine tabi tutulmuştur. Ulaşılan sonuçlara göre 2022 yılında he ne kadar kruvaziyer turist sayısı artış trendine girmiş olsa da 2017 ve 2018 yıllarının baz alındığı değişim pay analizlerine göre araştırma kapsamında yer alan limanları genel anlamda beklenen sayının gerisinde turistin ziyaret ettiği tespit edilmiştir.

Las relaciones de contigüidad de las comunidades con lagunas y manglares generan múltiples impactos que es necesario conocer y analizar para el diseño de estrategias de atención en el marco de los ODS 2030. El objetivo de este estudio fue analizar los principales problemas socioambientales en Pico del Monte-laguna de Chautengo, Guerrero. Se utilizó un enfoque mixto concurrente de tipo exploratorio. Incluyó una revisión documental, una inmersión en el área de estudio y percepción con la aplicación de encuestas (N = 65) y entrevistas a profundidad (N = 65); además, se analizó la cobertura del manglar utilizando los Sistemas de Información Geográfica (SIG). Los resultados mostraron que la comunidad de Pico del Monte presenta un crecimiento poblacional desordenado que la ha llevado a impactar la laguna de Chautengo. Los problemas socioambientales percibidos por la población son sobrepesca, contaminación por residuos sólidos urbanos y deforestación en la zona de manglar. Se concluye que la carencia de cultura ambiental, la falta de planeación territorial y servicios básicos, la poca aplicación de políticas públicas, y la ausencia de alternativas laborales provocan un deterioro en los ecosistemas y limitan el logro de los ODS 2030 en la comunidad.
