Published: September 2022

We demonstrate EDA4Sum, a framework dedicated to generating guided multi-step data summarization pipelines for very large datasets. Data summarization is the process of producing interpretable and representative subsets of an input dataset. It is usually performed following a one-shot process with the purpose of finding the best summary. EDA4Sum leverages Exploratory Data Analysis (EDA) to produce connected summaries in multiple steps, with the goal of maximizing their cumulative utility. A useful summary contains
k individually uniform
sets that are
collectively diverse
to be representative of the input data. EDA4Sum accommodates datasets with different characteristics by providing the ability to tune the weights of uniformity, diversity and novelty when generating multi-step summaries. We demonstrate the superiority of multi-step EDA summarization over single-step summarization for summarizing very large data, and the need to provide guidance to domain experts, by interacting with the VLDB'22 participants who will act as data analysts. The application is avilable at https://bit.ly/eda4sum_application.

Published: September 2022

A database service is required to meet the consistency, performance, and availability goals of modern applications serving a global user-base. Configuring a database deployed across multiple regions such that it fulfills these goals requires significant expertise. In this paper, we describe how CockroachDB makes this easy for developers by providing a high-level declarative syntax that allows expressing data access locality and availability goals through SQL statements. CockroachDB also enables many types of queries on the multiregion database to perform as well as they would in a single-region deployment, due to enhancements to the SQL optimizer, transaction, and replication layers. This paper showcases these features with a comprehensive demonstration scenario tracking a ride-sharing company's journey as they expand their application globally.
WebArrayDB

Published: September 2022

Geospatial array DBMSs operate on georeferenced
N
-d arrays. They provide storage engines, query parsers, and processing capabilities as their core functionality. Traditionally, those have been too heavy for a Web browser to support. Hence, Web Applications, mostly Geographic Information Systems (GISs), run array management on their server back-ends that return small portions of the results via the network. We showcase WebArrayDB, the first geospatial array DBMS that can run completely inside a Web browser. We demonstrate that modern Web browsers, JavaScript, and respective software libraries are sufficiently mature to build and run such a feature-rich and powerful DBMS. A Web-based array DBMS should reduce server load, enable offline work, decrease network I/O, and improve user experience. We also present ArrayGIS, our new Web GIS based on WebArrayDB, and invite everyone to explore both via a freely accessible, informative, and interactive Web GUI.
CERTEM

Published: September 2022

Entity resolution (ER) aims at identifying record pairs that refer to the same real-world entity. Recent works have focused on deep learning (DL) techniques, to solve this problem. While such works have brought tremendous enhancements in terms of effectiveness in solving the ER problem, understanding their matching predictions is still a challenge, because of the intrinsic opaqueness of DL based solutions. Interpreting and trusting the predictions made by ER systems is crucial for humans in order to employ such methods in decision making pipelines. We demonstrate CERTEM an explanation system for ER based on CERTA, a recently introduced explainability framework for ER, that is able to provide both saliency explanations, which associate each attribute with a saliency score, and counterfactual explanations, which provide examples of values that can flip a prediction. In this demonstration we will showcase how CERTEM can be effectively employed to better understand and debug the behavior of state-of-the-art DL based ER systems on data from publicly available ER benchmarks.
SENSOR

Published: September 2022

Sketching is a common approach to visually query time series data. However, a recent study reported that sketching a pattern for querying is "often ineffective on its own" in practice due to lack of "representative objects" to facilitate
bottom-up search.
In this demonstration, we present a novel
data-driven
sketch-based visual query interface (VQI) construction system called SENSOR to alleviate this challenge. Given a time series dataset, SENSOR automatically constructs its VQI by populating different components from the underlying data. Specifically, it discovers and exposes a set of representative objects in the form of
VST-aware shapelets
to facilitate query formulation. Such data-driven construction has several potential benefits such as empowering efficient
top-down
and
bottom-up
search and portability of the interface across different application domains and sources.

Published: September 2022

Sentiment analysis has received constant research attention due to its usefulness and importance in different applications. However, despite the research advances in this field, most current tools suffer in prediction quality due to the inconsistencies in their results, i.e., intra- and inter-tool inconsistencies. This demonstration proposes a system for the evaluation of sentiment analysis quality namely SA-Q. The system allows the evaluation of inconsistency in sentiment analysis tools, the resolution of the inconsistency using state-of-the-art methods and the recommendation of relevant sentiment analysis tool for any type of data set provided by the attendees. It allows the attendees to compare the tools. Moreover, we demonstrate that SA-Q evaluates the consistency of tools on two levels (intra-tool and inter-tool). Through various scenarios, we showcase the challenges of inconsistency resolution, demonstrate the usefulness of the proposed system and the recommendations that can be given to the attendees for their datasets. We demonstrate that SA-Q system has practical utility in many areas of industrial applications for better decision making. This demonstration shows promising research areas for data management, NLP, and machine learning communities by adopting and drawing inspiration from truth inference methods to create more robust tools and improve the tool's scalability.
DADER

Published: September 2022

Entity resolution (ER) is a core data integration problem that identifies pairs of data instances referring to the same real-world entities, and the state-of-the-art results of ER are achieved by deep learning (DL) based approaches. However, DL-based approaches typically require a large amount of labeled training data
(i.e.
, matching and non-matching pairs), which incurs substantial manual labeling efforts. In this paper, we introduce
DADER
, a hands-off deep ER system through domain adaptation.
DADER
utilizes multiple well-labeled source ER datasets to train a DL-based ER model for a new target ER dataset that does not have any labels or with only a few labels. To address the key challenge of domain shift,
DADER
judiciously selects labeled entity pairs from the source and then aligns distributions of the source and the target by using six popular domain adaptation strategies.
DADER
can also harness the users to gather a few labels for further improvement. We have built
DADER
as an open-sourced Python Library with intuitive APIs and demonstrated its utility on supporting hands-off ER in real-world scenarios.

Modern techniques for querying graph-structured relations
Authors: Mhedhbi Amine , Salihoğlu Semih
Published: September 2022

The last decade has seen an emergence of numerous specialized graph DBMSs (GDBMSs) as well as graph-optimized extensions of RDBMSs. In addition, several query processing techniques, such as worst-case optimal join algorithms and factorized query processing, have been introduced in the context of RDBMSs, which find their best applications on graph workloads. In this tutorial, we review the recent advances in query processing techniques for graph workloads. For each technique, we first overview the theoretical foundations. Then, we overview how DBMSs implement these techniques. Finally, we discuss the open challenges for existing implementation approaches.

Published: September 2022

In 2011, we proposed PathSim to systematically define and compute similarity between nodes in a heterogeneous information network (HIN), where nodes and links are from different types. In the PathSim paper, we for the first time introduced HIN with general network schema and proposed the concept of meta-paths to systematically define new relation types between nodes. In this paper, we summarize the impact of PathSim paper in both academia and industry. We start from the algorithms that are based on meta-path-based feature engineering, then move on to the recent development in heterogeneous network representation learning, including both shallow network embedding and heterogeneous graph neural networks. In the end, we make the connection between knowledge graphs and HINs and discuss the implication of meta-paths in the symbolic reasoning scenario. Finally, we point out several future directions.

The effects on deforestation of conditional cash transfers: a study among the Khĩsêtjê Amazonian indigenous people
Authors: Cunha P.R. , Neto C. Rodrigues , Morsello C.
Published: September 2022

Smallholders' contribution to Amazonian deforestation is currently increasing. In Indigenous Lands, changes in land uses might be partially due to the unintended effects of anti-poverty strategies, including the Conditional Cash Transfers (CCTs), which may promote the conversion of
forests to agricultural lands. Despite that, little is known about whether and how CCTs affect long-term deforestation rates. Thus, this study has assessed whether CCTs influenced long-term land-use changes from forests to agriculture, considering alternative time allocation assumptions (i.e.,
Time Optimisation and Time Budget). Transfers from the Brazilian Bolsa Família Program to the Khĩsêtjê indigenous people of the Amazon were evaluated with two agent-based models. Results suggest CCTs will likely decrease the area deforested in the long term
without changing Khĩsêtjê's population size. When market-purchased products replace local products, people's time allocated to agriculture is expected to fall. The intensity of CCT effects on deforestation varied according to time allocation assumptions, highlighting the
importance of considering them carefully to improve the predictions from model simulations.

Published: September 2022

Socio-economic and political contexts play a major role in a community's perception of the environment, determining natural resource use. We examined perceptions of forest and forest resource use among two Hutsul communities in Bukovina sharing a similar cultural background but living
in a region divided by the national border created between Romania and Ukraine in the 1940s. Twenty-nine open-ended and 61 semi-structured interviews were conducted with Hutsuls from Romania and Ukraine. Hutsuls across the border mostly share perceptions of forest benefits, while they differ
in perceptions of environmental changes and the drivers of these changes. Hutsuls of Ukraine showed a greater connectedness and a stronger tie to the forest as an essential element of their livelihoods. Moreover, Hutsuls in Ukraine rely more on forest medicinal plants than do Hutsuls in Romania.
Hutsuls' perspectives on the negative impact of current forest management policies should be a cornerstone for redesigning sustainable forest management plans.
Motivation and factors affecting Indigenous People's willingness to participate in future REDD+ project activities: the case of Tagal Hutan in Sabah, Malaysia
Authors: Musthafa I.Z.F. , Y-C Youn
Published: September 2022

The Kadazandusun people of Sabah have practiced traditional forest management of tagal hutan or prohibited forests. An official development assistance (ODA) project under REDD+ implementation scheme targets tagal hutan forests in Sabah, with the participation of the indigenous
people. Through the theory of planned behaviour, this study assesses the link between attitude, social norms, customary norms, and perceived behaviour control on Kadazandusun people's intentions to participate in future REDD+ project activities. We found out that attitude and perceived behaviour
control affect intentions to participate in future REDD+ project activities meanwhile social norm and customary norm were otherwise. Socio-demographic factors, such as household size, age, and prior experience as leaders or committee members in the village, also influence the intentions to
participate in future REDD+ project activities. This study may help predict the acceptance of REDD+ activities among indigenous people in Sabah and help design more effective REDD+ projects.
Recognizing Indigenous and Traditional Peoples and their identity, culture, rights, and governance of forestlands: Introduction to the Special Issue
Authors: Wyatt S. , Bulkan J. , Jong W. De , Gabay M.
Published: September 2022

This Special Issue aims to provide an overview of the diversity of international research on the multiple ways in which Indigenous and Traditional peoples (ITP) are engaged in occupying and governing forest landscapes, consistent with their rights, values, knowledge and customs. This Introduction begins by reviewing our evolving understanding of two key questions: what rights are held by ITP; and how "Indigenous" and "Traditional" are actually defined. Papers in this Special Issue examine different concepts in more than a dozen countries on five continents and, while each study and each people is distinct, we identify several common themes. Firstly, traditional knowledge, values, and practices are central to the relationship between ITP and forest landscapes and underlie the effectiveness of other interventions. Secondly, early efforts to use forests to promote economic development have given way to a deeper understanding of the ways in which diverse products, services, and cultural values of forest landscapes support livelihoods for both ITP and other populations. Thirdly, governance is a common theme in this Special Issue, especially in terms of relations between ITP and the State and in the effectiveness of policies and programs. A fourth theme is that of understanding how the knowledge, practices and values of individuals and groups can help predict perceptions of forests and preferences for management. Finally, this Special Issue showcases a wide variety of methodological approaches, both qualitative and quantitative, helping researchers recognize the advantages and limits of each. Taken together, the papers in this Special Issue illustrate multiple characteristics of relationships between ITP and forest landscapes, and their aspirations to maintain their culture, their knowledge, their rights, and their livelihoods.

The main goal is to develop a local theory in the energy space and to investigate some issues of the global theory.
Indeed, using a standard contraction argument coupled with Strichartz estimates, one obtains a local solution in the inhomogeneous Sobolev space

(

H

)

{(H^{1})^{m}}

for the energy sub-critical regime.
Then the local solution extends to a global one in the attractive regime; also in the energy critical case there is a global solution with small data.
For a repulsive source term, by using the potential well theory with a concavity argument, the local solution may concentrate in finite time or extend to a global one. Finally, in the inter-critical regime, one proves the existence of infinitely many non-global solutions with data near to the stationary solution. Here, one needs to deal with the coupled source term which gives some technical restrictions such as

p

{p\geq 2}

in order to avoid a singularity.
This assumption in the inter-critical regime gives a restriction on the space dimension.
On the effect of array size on the radar cross section reduction bandwidth of checkerboard metasurfaces
Authors: Murugesan Akila , Selvan Krishnasamy T.
Published: September 2022

This paper reports investigations on the effect of array size on the RCS reduction bandwidth of checkerboard metasurfaces (CMS). Three CMSs, one on a Rogers substrate and the remaining on FR4, are considered. While the usual phase deviation criteria are used for the designs on both the substrates, additionally a set of modified criteria recently proposed are used for the FR4 substrate-based designs. While three different sizes – 120 mm2, 240 mm2, and 480 mm2 – are considered for the simulation-based investigations for all the structures, an additional size of 600 mm2 is also considered for one of them. The 8 and 10 dB RCS reduction bandwidths drop as array size increases. The bandwidth reduction is attributable to mutual coupling, as has been reported in an earlier study. As therefore expected, all of the three structures, for all sizes, present the same RCS reduction bandwidth when a mutual coupling mitigation technique is incorporated. For 10 dB RCS reduction bandwidth, this value approaches that estimated by using a mutual coupling independent semi-empirical equation that holds for infinite arrays.
Split monotone variational inclusion problem involving Cayley operators
Authors: Rahaman Mijanur , Ishtyak Mohd. , Ahmad Iqbal , Ahmad Rais
Published: September 2022

In this article, we introduce a new kind of split monotone variational inclusion problem involving Cayley operator in the setting of infinite-dimensional Hilbert spaces. We develop a general iterative method to approximate the solution of the split monotone variational inclusion problem involving Cayley operator. Under some suitable conditions, a convergence theorem for the sequences generated by the proposed iterative scheme is established, which also solves certain variational inequality problems related to strongly positive linear operators. Finally, a numerical example is presented to study the efficiency of the proposed algorithm through MATLAB programming.

Concussion-related visual memory and reaction time impairment in college athletes improved after osteopathic manipulative medicine: a randomized clinical trial
Authors: Mancini Jayme D. , Angelo Nicole , Abu-Sbaih Reem , Kooyman Patricia , Yao Sheldon
Published: September 2022

Context

Concussion is an acute, transient disruption in brain function due to head injury. Previous studies suggest osteopathic manipulative medicine (OMM) improved recovery from concussion.

Objectives

The hypothesis was that new-onset impairments (NOI) of neurological functions identified by Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) will improve more so after OMM than after concussion-education.

Methods

College athletes presenting to the outpatient academic healthcare center (AHCC) with concussion due to head injury within the preceding 2 weeks were recruited for this IRB-approved, randomized, single-blinded trial. Consented men and women were randomized into groups receiving two OMM treatments or two concussion-education sessions to control for social effects. Preseason, Baseline, ImPACT was compared to Post-Injury scores to determine NOI. Baseline, Post-Injury, and Post-Interventions ImPACTs were compared by analysis of variance (ANOVA, α≤0.05). Post-Injury correlations and mean changes in King-Devick (KD) scores were analyzed.

Results

Post-Injury NOI were found in 77.8% (14/18) men and 85.7% (6/7) women, including ImPACT subscore indices for verbal and visual memory, processing speed (PS), and reaction time (RT). Of those with NOI, mean visual memory recovered by 50.0% following one and by 104.9% (p=0.032) following two OMM treatments in men and by 82.8% (p=0.046) following one treatment in women. Following two interventions, the mean RT in men receiving OMM improved by 0.10 more than education (p=0.0496). The effect sizes of OMM were large (Cohen’s d=1.33) on visual memory and small (Cohen’s d=0.31) on RT.

Conclusions

The NOI in visual memory and RT following concussion significantly improved in the OMM group compared to the education group. Integrating OMM utilizing physical exam and this treatment was a safe individualized approach in athletes with acute uncomplicated concussions. Further research is warranted to improve the utilization of OMM for individuals with concussion.

Authors: . DANAISH , Zongjin Ren , Jun Zhang , Guo Xu’tian , Akbar Muhammad Ayaz
Published: September 2022

High-accuracy measurement for force is essential in the Robotics design, Rocket thrust, manufacturing process, and biomedical equipment. To realize the multi-dimensional force/moment measurement, a multi-points force / moment measurement piezoelectric dynamometer capable of measuring spatial force information has been developed. The experimental prototype dynamometer is fabricated according to the designed numerical simulation model (Finite element method: FEM) in which eight three-axis piezoelectric sensors are uniformly distributed in a zigzag pattern. The constructed dynamometer is calibrated both statically and dynamically, static calibration is carried out using a manual hydraulic loader, and the dynamic calibration is performed by impact load technique. The maximum error difference between the theoretical simulations and experimental analyses is approximately 7%. The experimental calibrated results evaluate that the cross-talk error of the applied axile force, normal force and pitch moment is less than 4% and the natural frequency  of the dynamometer in each coordinate is greater than 0.35 kHz.
Tribological behavior of steel-steel pair: Influence of roughness and cutting parameters
Authors: Bouhabila Hamoudi , Bouchoucha Ali , A. Merabet  , R. Benzerga  , C. Le Paven
Published: September 2022

Roughness characterizes the quality of the machined surfaces, mainly determined by the geometric tolerances and induced by the different factors involved in the cutting process. The aim of this paper is to study the influence of cutting parameters (cutting speed (Vc), feed rate (f), tool nose radius (Rc) and cutting depth (ap)), on the cylinder surface roughness, in order to value the friction coefficient (μ) and the wear rate (W) of the contact surfaces of steel-steel pair: 42CrMo4-20MnCr5. Full factorial design (DOE) of 9 tests is used, to develop theoretical model of the roughness of machined metal parts on turning. Hence, the influence of the cylinder roughness on the friction and wear behavior of the steel-steel pair contact  is studied, using a pin-cylinder tribometer. The results revealed that the friction coefficient and wear rate, increases progressively by varying the surface roughness (cutting parameters). The processing and observations of the results were recorded using a profilometer, an optical microscope, a scanning electron microscopy (SEM) followed by an analysis in energy dispersive spectroscopy (EDS). However, the surface of the pin is plowed, cracked and plastically deformed, thus inducing more loss of material by adhesion and oxidation of the formed particles on the cylinder, which bring about a material transfer and formation of a metal oxide layer.

To achieve this objective, a wind tunnel was used to study the flow around this drone in order to better understand the aerodynamic phenomena and to obtain some initial estimates of the lift, drag and moment coefficients, at three different Reynolds numbers of 4.02×104, 6.03×104 and 8.04×104, and for different angles of attack, from [−45°, +45°] with step of 1°.The experimental results obtained in this work show an casi-symetrical variation bertwen the negatif and positif incidence angles of the lift coeffecient, wiche indicate that the heliplane can fly in an inverted position, whatever the angle of incidence. Moreover, the minimum mean value of drag coeffecient according 1° incidence angle is 0.0478  then the drag due to geometry and pitching moment can never be canceled.

Is thyroglobulin detection in fine-needle aspirates useful for the diagnosis of central neck metastatic papillary thyroid cancer?
Authors: Song Yuntao , Wang Jiaxin , Zhu Yanli , Xu Guohui , Wang Tianxiao , Zhang Bin
Published: September 2022

Objective

The central neck lymph node (LN) status is important for the treatment strategy of papillary thyroid cancer (PTC), while the diagnosis is difficult. This study aims to evaluate the diagnostic value of fine-needle aspiration (FNA) and its washout thyroglobulin (FNA-Tg) detection in central neck LN metastasis.

Methods

Central neck LNs with FNA cytology (FNA-C) and FNA-Tg measurements from a tertiary hospital were included. Tg levels were correlated with histopathological or follow-up results. The diagnostic performance of FNA-C, FNA-Tg, and combining FNA-C and FNA-Tg for detecting LN metastasis was assessed.

Results

A total of 132 LNs in the central neck from 129 patients were studied. The median FNA-Tg concentration of 74 metastatic LNs was 552.5 ng/mL, whereas, in 58 benign LNs, the median Tg concentration was 0.1 ng/mL (P < 0.001). Receiver operating characteristic analysis (area under the curve, 0.861) was used, and a cutoff value of 14.6 ng/mL was obtained. There was no significant increase in the diagnostic accuracy when FNA-Tg was used or combined with FNA-C, compared with FNA-C alone. The size, location of LNs, the presence of the ipsilateral thyroid gland, and Hashimoto's thyroiditis did not affect the incidence of misdiagnosis.

Conclusions

FNA-C is the gold standard for evaluating central neck metastasis in PTC patients. Measurement of Tg levels in FNA washout does not improve the diagnostic accuracy any further.

This work aimed to experimentally determine of the Kearns texture parameters, elastic moduli, mechanical properties (ultimate tensile strength and yield strength) of sheets of an alloy of Mg 5 wt. % Li after various types of processing: 1) extrusion at 350 ° C through a rectangular die; 2) rolling with a change in its direction by 90° and intermediate annealing at 350°C after each pass; 3) after the subsequent alternating bending (AB) by 0.5; one; 3 and 5 cycles and evaluation of the elastic and mechanical properties of the corresponding single crystal of the alloy under study using the indicated data. The moduli of elasticity and strength characteristics of the studied polycrystalline samples were determined in the rolling direction (RD) and transverse direction (TD). Using the found parameters of the Kearns texture and the elastic and mechanical properties of the sheets, the values of the elastic modules and the ultimate strength and yield strength of the single crystal of the above alloy were estimated. The found modules of elasticity of a single crystal of an alloy Mg-5 wt. % Li deviate from their values found in previous studies by no more than 7.5%. Elastic modules and strength characteristics of the studied samples of magnesium alloy Mg 5 wt. % Li calculated from the single crystal data deviate from the experimental data by no more than 10%.
Effects of crosslinking degree on the coating properties of arabinoxylan
Authors: Hu Zhenhua , Xiang Zhouyang , Song Tao , Lu Fachuang
Published: September 2022

Arabinoxylan (AX) was extracted from sugarcane bagasse and modified through crosslinking with glutaraldehyde (GA). The effects of crosslinking degree on the rheological and coating properties of glutaraldehyde crosslinked arabinoxylan (GAX) were investigated. To better evaluate the degree of crosslinking, the crosslink index was used to represent the degree of crosslinking for the GAX in this study. The viscosity of the GAX solution increased when the degree of crosslinking increased, and the solution demonstrated non-Newtonian flow behavior. A high degree of crosslinking was detrimental to the film and coating properties of the GAX. At an optimum degree of crosslinking, the tensile strength of the GAX films increased by approximately 170% and 60% compared with that of the AX and GAX with the highest degree of crosslinking, respectively; the tensile strength of the GAX-coated paper increased by approximately 15% compared with that of the GAX with the highest degree of crosslinking. When calcium carbonate was mixed with the paper coating adhesives, the GAX showed comparable coating properties to that of polyvinyl alcohol, demonstrating its potential to substitute petroleum-based paper coating adhesives.

The article examines marginalia in one of the East Slavic hand-written versions of “Annales Ecclesiastici” by Caesar Baronius (Russian State Library, f. 256, no. 16, 17th century) in comparison with the Latin original, the Polish translation of Piotr Skarga published in 1607, and other Slavic versions from the 17th–18th centuries. Marginal comments of the book apparatus were studied in a pragmatic aspect, which took into account the narrative impact on the reader; glosses were analyzed in terms of lexemes’ interaction, considering their various origins and stylistic status. The author comes to the conclusion that the historical narrative formed through comments has a profoundly original nature. In the analyzed manuscript, the comments do not always follow Skarga’s commentaries: in part, their contents are possibly influenced by the Latin original, and in part, they represent their own emphases and judgments. The linguistic analysis shows that the vocabulary of Polish or Ruthenian origin (both with Slavic and non-Slavic (Greek, Latin, and German) roots) is glossed widely but inconsistently. The words of Greek and Slavic origin, which may have explanatory functions, are stylistically associated with both the literary Old Church Slavonic tradition and business writing. Less often, Polonisms can themselves play the role of explanatory marginalia.
Spoon, Knife and Fork across Slovenian Dialects
Authors: Gostenčnik Januška , Kumin Horvat Mojca
Published: September 2022

The article presents Slovenian dialect names for cutlery used in eating or preparing food – spoon, knife and fork, from a geolinguistic, word-formational as well as etymological and semantic-motivational perspective. The ethnological framework serves in particular to present the reasons for the (non-)borrowing of lexemes. It turns out that the terms for spoon and knife are not diverse from the point of view of borrowing, since the denotata have been in use in the Slovenian language area for a relatively long time. The fork was introduced relatively late as part of cutlery, so the most common name for it is a word-formational diminutive, and a high level of lexeme borrowing is observed in contact with the non-Slavic language area. The name for knife demonstrates word-formational diversity due to different uses in the past. The lexemes nožič, vilice and razsoška or plural razsoške have undergone a word-formational change, as they have kept their structural suffixes, but these do not (or rather, no longer) carry word-formational meaning; they are thus tautological derivations. The lexemes nož and pošada display a semantic change, as the meaning of both has narrowed in the hypernym → hyponym direction.
Polish zielony and Lithuanian žalias: Prototypes and Connotations
Authors: Ušinskienė Viktorija
Published: September 2022

The paper presents the results of the contrastive semantic analysis of the Polish lexeme zielony ‘green’ and its Lithuanian equivalent žalias. The research based on the methodology of R. Tokarski and K. Waszakowa is aimed at comparing the collocability of Pol. zielony / Lith. žalias with names of various objects and phenomena (both in the literal and figurative senses) including the identification of the prototype references and connotative meanings. The analysis has illustrated that in both languages, ‘green’ is interpreted primarily as the color of grass or other plants, but for some shades of green, the color of certain minerals (such as emerald or malachite) can be considered a prototype pattern. Common prototypical references clearly motivate similar symbolic and cultural values of Polish and Lithuanian terms. Pol. zielony / Lith. žalias have similar ranges of use and develop quite convergent connotative meanings, of which there are slightly more in Lithuanian. In both languages, the prototype association with the green of young plants creates the following connotational meanings: ‘young’, ‘fresh’, ‘unripe’, ‘immature’, ‘inexperienced’, ‘healthy’, ‘ecological’. Both in Polish and in Lithuanian, some shades of green can connote not only positive but also negative characterizations, based on associations with the chthonic world or with disease and death. However, such connotations as ‘raw, uncooked’ and ‘nice, pleasant’ are more typical for the Lithuanian language, since in Polish they are rather sporadic. Only in Lithuanian there is the connotation ‘strong, powerful’. Therefore, it must be recognized that the semantic spectrum of the Lith. žalias is wider than the semantics of its Polish equivalent.

She studied the Old Believers for many years, was a specialist in Russian aspectology, as well as the Old Believers of Estonia and Latin America. She initiated interdisciplinary studies of the language and culture of the Old Believers' chapels of South America, immigrants from China. In 2006–2008 Rovnova organized reconnaissance dialectological expeditions to Old Believer settlements in Argentina, Uruguay, Bolivia, and Brazil; in 2009, she visited the Old Believers of Australia (Sydney, Brisbane). The results of the researcher's many years of field work are her numerous articles published in various scientific journals in Russia and abroad (a total of more than 140 scientific papers), scientific reports at Russian and international conferences, popular science educational speeches and lectures.
Outcomes of Cardiac Arrest in Brunei Darussalam

Published: September 2022

Cardiac arrest outcomes in Brunei Darussalam have not been previously reported. The mean (SD) time of arrest to cardiopulmonary resuscitation in hospital was 1.6 min (2.31 min; range 0–6 min) compared to the mean (SD) time of arrest to first cardiopulmonary resuscitation out of hospital of 19 min (23.91 min; range 0–87 min). The majority (71.2%) were out-of-hospital cardiac arrests (OHCA) (versus in-hospital cardiac arrests (IHCA)). One-year median survival for cardiac arrests was 1.4% which is below survival rates reported by other groups previously. Median 1-month survival rates were 25% for IHCA versus 5% for OHCA. Survival rates at 1 month for shockable rhythms were better (40%; p<0.001) for IHCA versus 16.7% for OHCA. Survival from cardiac arrests is low in Brunei Darussalam. This is associated with low rates of bystander cardiopulmonary resuscitation and may need to be addressed to improve outcomes.
Movilidad y turismo sexual en la ciudad de Taxco, México
Authors: Urióstegui Flores Adrián
Published: September 2022

Objetivo a) estudiar la movilidad y el turismo sexual que realizan trabajadores de taxis de la ciudad de Taxco, Guerrero, México y b) analizar los datos de casos confirmados del Virus de la Inmunodeficiencia Humana (VIH) y Síndrome de Inmunodeficiencia Adquirida (SIDA) en el municipio de Taxco, del año 2006 al 2016.
Materiales y Métodos El estudio fue de tipo cualitativo no probabilístico. Se diseñó un cuestionario de entrevista de preguntas abiertas, y se aplicó a 30 trabajadores de taxis en la ciudad de Taxco, Guerrero, México. También se entrevistó a cinco médicos especialistas (informantes clave anónimos).
Resultados El 60% (18 casos) del grupo entrevistado manifestó haber contratado sexo-servidoras. Las ciudades a donde se acudió en mayor medida para dicha actividad fueron Jojutla (Estado de Morelos), Iguala y Taxco (Estado de Guerrero) y Ciudad de México. Se registró un total de 72 casos confirmados de VIH y sida en los 10 años considerados.
Conclusiones La ciudad de Jojutla fue el lugar más visitado en cuestión de movilidad con motivo de contratar dicho sexoservicio. En lo anterior influyeron determinantemente tanto los bajos precios, como la corta edad de sexoservidoras que lo frecuentaban. Finalmente, las afirmaciones de especialistas en salud entrevistados confrontan los datos estadísticos oficiales sobre casos de VIH/sida.

Objetivo Caracterizar la población afectada por tuberculosis multidrogorresistente y resistente a rifampicina (TB-MDR/RR) en Colombia.
Métodos Estudio transversal a partir de la información nominal de los pacientes con TB-MDR/RR tratados y reportados en Colombia desde 2009 hasta 2020, usando la totalidad de las fuentes de información oficiales. Se compararon, además, las tasas de TB-MDR/RR de diferentes grupos de riesgo con la de la población general y se evaluaron variables asociadas a la TB-MDR/RR extrapulmonar y a resistencias medicamentosas.
Resultados La TB-MDR/RR ha aumentado progresivamente durante la última década y se ha concentrado en hombres (64% vs. 36%, p<0,001), edades medias (mediana: 39,5 años; RIC: 27) y zonas de mayor densidad poblacional (59% de los casos en Antioquia, Valle del Cauca y Santiago de Cali). Además, al compararlas con las poblaciones de referencia que aplicaran, se evidenciaron tasas 2, 10 y 200 veces mayores en población indígena (9,45/1 000 000 vs. 4,31/1 000 000; p=0,02), prisioneros (169/1 000 000 vs. 16,9/1 000 000; p<0,001) y habitantes de calle (21/100000 vs. 0,1/100 000; p<0,001), respectivamente.
Conclusiones El aumento en los casos de TB-MDR/RR y sus grupos de riesgo deben tenerse en cuenta para la planeación de políticas, distribución de recursos y atención clínica.
Composición y evolución del gasto en salud de Colombia y su financiamiento en el periodo 2013-2018
Authors: Barón-Leguizamón Gilberto
Published: September 2022

Objetivo Examinar la magnitud, la composición y evolución del gasto en salud de Colombia y su forma de financiamiento durante el periodo 2013‑2018, con el propósito de aportar evidencia reciente para el mejor conocimiento y seguimiento de los flujos de recursos del sistema de salud.

Métodos El análisis se sustenta en los conceptos y clasificaciones de la metodología SHA-2011 adoptada en la actualidad por la mayoría de los países miembros de la Organización Mundial de la Salud para sus estimaciones anuales del gasto en salud. La fuente principal de información es la base de datos de gasto global en salud de la misma entidad, algunos de cuyos resultados se complementan con cálculos adicionales utilizando fuentes oficiales nacionales.

Resultados Desde el lado del gasto, el componente más importante corresponde al gasto público en salud, el cual representa, en promedio, 76,4% del gasto corriente en salud para el periodo en referencia, cuyo financiamiento con recursos públicos fiscales y contribuciones a la seguridad social representa 70,6% del financiamiento total; en tanto que el restante 23,6% corresponde al financiamiento privado representado por los pagos de bolsillo de los hogares (15,8%) y los pagos de seguros voluntarios (7,8%) también como promedios del mismo periodo.

Conclusiones Colombia, como la mayoría de los países latinoamericanos, sigue un modelo de financiamiento predominantemente público, cuya composición de fondos registró un cambio en favor de los recursos de origen fiscal, como resultado de un cambio en las políticas de financiamiento durante el periodo analizado.
