Enregisterment eines /r/-Allophons?
Authors: Kehrein Roland
Published: October 2021

In the study presented in this paper the use of a specific linguistic non-standard feature of German by 100 speakers representing three generations was analysed. The speakers originate from 25 different locations within the Middle Franconian dialect formation covering the middle-western parts of Germany. The feature analysed is the realisation of the Standard German phoneme /r/ as a voiceless velar or uvular fricative [x, χ] when following a short vowel and preceding a coronal obstruent. The comparison of how frequently the speakers use [χ] in different communicative contexts results in the observation of three types of speakers (i. e., [χ] users): The first type are dialect speakers mostly of the older generation (60 years and above) who use the variant in a traditional manner, namely when aiming at producing their best way to pronounce Standard German. According to these speakers [χ] forms part of the Standard German pronunciation norm. The second type is mainly represented by middle aged speakers (45–55 years) who use the feature in nearly all communicative contexts except when they have a dialect competency and are asked to produce their “strongest dialect”. Finally, the third type of speakers are mainly young people (17–23 years) who do not have any dialect competence. These speakers only use [χ] when they are asked to produce their “strongest dialect” and/or when they are talking to friends. On the basis of these results it is argued that, between these types of speakers and the generations they represent, a re-evaluation of the feature has taken place that may be classified as enregisterment, because speakers of the third type seem to use [χ] indexically in order to signal familiarity with their interlocutors on a interpersonal-social level.
Zum variationslinguistischen Verhältnis von Stadt und Land.
Authors: Pickl Simon , Pröll Simon , Elspaß Stephan
Published: October 2021

In this paper, we explore the geolinguistic relationship between urban and rural areas through the conceptualisation and modeling of spatial topologies. Geolinguistic topologies concern the structure of the mutual linguistic relationship between localities. They can be defined either deductively or on the basis of empirical data and represent the linguistic similarities or distances between localities. We operationalise and apply several such topological models to Austrian data from the Atlas zur deutschen Alltagssprache (AdA), a linguistic atlas documenting colloquial German using crowd-sourcing methods. The results are evaluated on the basis of statistical examination and of visualisations of the topological relationships predicted by the models. It is confirmed that linguistic similarity is determined both by geographical distance and by the distribution of population, but the exact relationship is complex: Not only do smaller geographic distances on the one hand and higher population numbers on the other hand bring about increased linguistic similarity; the relevance of these two factors for linguistic similarity varies with population size, too, such that linguistic relationships between cities are determined more by their size and less by their distance, while for smaller locations the opposite is true. Hence, no single topological model can be identified as superior; instead, the individual models emphasise different aspects of the linguistic relationship between urban and regional language usage.
Key Concepts in Advertising: Deceptiveness
Authors: Richards Jef I.
Published: October 2021

Abstract: Keywords in Advertising articles provide short lectures on an important concept to help understand advertising’s place in society, culture, history, and the economy. This article focuses on deceptiveness: the legal concept that guides regulation of advertising that misleads consumers. It explains the distinction between various terms that seem synonymous, and which terms have legal salience. The basic purpose of the law is discussed, providing context for understanding the legal construct. Some examples are presented, illustrating the points made. Some limitations on regulation also are addressed.

Digital Collection: Gender Roles in Cream of Wheat’s Comic Strip Advertisements Featuring Li’l Abner and Daisy Mae
Authors: Parkin Katherine
Published: October 2021

Abstract: This digital collection offers insights into the Cream of Wheat campaign that built on the cultural cache of cartoonist Al Capp’s Li’l Abner comic. The strip, created in 1934 and running until 1977, featured a cast of over one hundred white characters in a poor, rural, mountainous United States. It was wildly popular, sparking merchandise, restaurants, and a Broadway show. Starting in the 1940s, ads showcased the strong, handsome Li’l Abner consistently relying on Cream of Wheat’s 5-minutes-to-prepare hot cereal to rescue women and escape marriage, including on Sadie Hawkins Day, a day of gender role reversals. In the United States and around the world, people embraced Sadie Hawkins Day by having girls ask boys to a dance, a unique challenge to gender norms. The voluptuous, beautiful Daisy Mae suggested that women were always desperate to be married. When Capp had Li’l Abner marry in the early 1950s, Daisy Mae proclaimed her success in knowing that Cream of Wheat was the way to win men’s hearts. Advertising in this campaign served not only to sell Cream of Wheat, but advanced entrenched ideas about race and gender roles.
Influence of acetate containing fluid versus lactate containing fluid on acid-base status, electrolyte level, and blood lactate level in dehydrated dogs
Authors: Heitland Annika , Klein-Richers Ute , Hartmann Katrin , Dörfelt René
Published: October 2021

Background and Aim: Acetate or lactate buffered, balanced isotonic rehydration fluids are commonly used for fluid therapy in dogs and may influence acid-base and electrolyte status. This study aimed to assess acid-base status, electrolyte levels, and lactate levels in dehydrated dogs after receiving acetate or lactate-containing intravenous rehydration fluids.

Materials and Methods: In this prospective, randomized study, 90 dehydrated dogs were included and randomized to receive acetate [Sterofundin® ISO B. Braun Vet Care (STERO), Germany) or lactate (Ringer-Lactat-Lösung nach Hartmann B. Braun Vet Care (RL), Germany] containing intravenous fluids for rehydration. The exclusion criteria were as follows: Age <6 months, liver failure, congestive heart failure, and extreme electrolyte deviation. Physical examination, venous blood gas, and lactate levels were analyzed before and after rehydration. The two groups were compared using t-test and Chi-square test. The significance level was set at p≤0.05.

Results: Post-rehydration heart rate decreased in the STERO group (p<0.001) but not in the RL group (p=0.090). Lactate levels decreased in both groups STERO (p<0.001) and in group RL (p=0.014). Sodium and chloride levels increased during rehydration in group STERO (p<0.001; p<0.001) and group RL (p=0.002; p<0.001). There was a larger decrease in lactate levels in group STERO compared to group RL (p=0.047).

Conclusion: Both solutions led to a mild increase in sodium and chloride levels and decreased lactate levels. The acetate-containing solution had an inferior effect on the decrease in lactate level.

Published: October 2021

This research aims to describe and to define the importance of spirituality as a mediator in the global pandemic situation of COVID-19 in Pakistan while having positive correlation with resilience and inverse with hopelessness. The correlational research design was used and data was gathered by simple random sampling and there was a use of standardized psychological instruments to measure the variables. The participants were (N=540) Pakistani general population (male and female) with the age range of 18–60. The outcomes revealed that resilience was positively correlated with spirituality (r=0.72; p <0.01) while spiritualty is negatively correlated with hopelessness (r=-0.76; p <0.01) and resilience was negatively correlated with hopelessness (r=-0.78, p <0.01). Mediation analysis shows that spirituality performed a strong intermediating role between resilience and hopelessness the direct effect of hopelessness  on resilience  was -5.9** whereas the indirect effect through spirituality was       -1.7** and the total effect size was – 7.6**. It is revealed that spirituality has a strong impact on the resilience behavior and reduces the hopelessness even in the worldwide disastrous situation. This study enhances the literature related to the psychological research and prompts the role of spiritual coping strategies especially in the state of uncertainty like coronavirus pandemic.

Published: October 2021

The article describes the laboratory germination and seed dormancy duration of five Trollius species andfour hybrids, which has been grew ex situ. The species and forms with high seed germination were detected from the dataobtained: T. ledebourii Rchb. (92 %), T. chinensis Bunge (93,5 %) end T. chinensis × T. ledebourii (82 %). Besides a high germination, the T. ledebourii seeds have the short dormancy period (22 days) and good sprouts. Therefore, the T. ledebourii seeds can be recommended for both autumn and spring sowing. The above mentioned Trollius species and forms arepotential for ornamental cultivar creation by further selection. The seeds of following species and forms T. apertus Perf.ex Igoschina, T. europaeus L., T. sajanensis (Malyschev) Sipliv., T. asiaticus × T. sajanensis, T. ledebourii × T. altaicus and T.× cultorum have low germination and long dormancy period. The examination of stratification treatment parameters andagrotechnical measures is needed for the germination of these seeds to get higher.
Ecological assessment of some Polygonatum odoratum (Mill.) Druce habitats
Authors: Dushina E. E.
Published: October 2021

Polygonatum odoratum (Mill.) Druce – summer-green short-rhizome polycarpic, geophyte. The aim of thestudy is to assess the ecological-cenotic preferences of P. odoratum in pine forests on the territory of the specially protectednatural area “Medvedsky Bor” in the Nolinsky district of the Kirov region. The ecological preferences of the P. odoratumwere determined by processing our own geobotanical descriptions according to the ecological scales of D. N. Tsyganov(1983), the assessment of the habitat conditions of the P. odoratum cenopopulations was carried out taking into accountthe realized ecological valence (REV) and the coefficient of ecological efficiency (K.ec.eff.). As a result of the studies, it wasfound that P. odoratum in pine forests is characterized by a wide potential range for most of the factors considered, in particular, the habitation of P. odoratum on sandy soils is due to the wide potential range of endurance of individuals of thisspecies in relation to soil moisture and preference for soils poor in mineral nutrients. The range of the studied habitatsdoes not go beyond the potentially possible boundaries, therefore, the conditions of these territories are relatively consistent with the ecological needs of the species, but most of the soil factors are not optimal for the growth of individuals of theP. odoratum in both cenopopulations. This is evidenced by both the low indicators of the realized ecological valence, andthe low coefficient of ecological efficiency

Published: October 2021

The paper presents the results of a study of the anatomical and morphological parameters of Pinus sylvestris L. growing in a serpentinite quarry in the Middle Urals. Morphological and anatomical changes have been identified,that are adaptive in nature and contribute to the survival of the species in extreme environmental conditions. P. sylvestrisunder open pit mining conditions shows a significant decrease in morphometric parameters, such as tree height and annual growth of the trunk. Under the influence of unfavorable factors (lack of mineral nutrients, lack of water, high rockiness of the substrate), the length and diameter of the needles decreased. Of the anatomical features, it is important to notea decrease in the number of resin passages with an increase in their diameter, a decrease in the diameter of the central cylinder and the area of the mesoderm.

Published: October 2021

New diatom strains of Nitzschia were isolated from phytoplankton and benthos of saltwater lakes inMongolia. The strains were identified based on morphological characteristics and phylogenetic analysis using the 18SrDNA gene. The new strains have been included into the Bacillariales clade with a high statistical support. Analysis ofthe fatty acid composition of the studied strains showed that 16:0 palmitic, 18:0 stearic, and 16:1 palmitoleic acids weredominant – they accounted for up to 97.5 % of the total fatty acids. New strains of Nitzschia from Mongolian lakes showedthe minimum content of polyunsaturated fatty acids, including omega-3 and omega-6. Taking into account the peculiaritiesof the profiles of fatty acids, and primarily the amount of saturated and monounsaturated acids, new strains of Nitzschiacan be considered for biotechnological use as a potential raw material for the production of biofuel.

The Baikal-Lensky State Natural Reserve was established in 1986. It covers a part of the north-western coastof Lake Baikal from Cape Onholoy to Cape Elokhin and the adjacent section of the Baikal ridge. The article describes thecharacteristics of the natural conditions of the reserve. Large-scale studies of the bryophyte flora in the reserve have not beencarried out. Currently, 195 species of bryophytes are known here (37 species of liverworts and 158 species of mosses). The listof bryophytes of the Baikal-Lensky Nature Reserve contains 33 species of liverworts and 135 leafy mosses. Platydictya acuminata (Lindb. et Arnel) Ignatov and Hamatocaulis vernicosus (Mitt.) Hedenäs are included in the Red Book of Irkutsk Oblast.Bryological material on the Baikal-Lensky nature reserve, collected by N. V. Stepantsova, has been analyzed. New species ofliverworts (4 species) and leafy mosses (19 species) were revealed. The territory of the Baikal-Lensky Nature Reserve requiresspecial bryological studies. Taking into account the peculiarities of the natural conditions of the reserve, we assume a significant replenishment of the list of bryoflora. We believe that the bryoflora of the Baikal-Lensky Reserve has been studied by lessthan 50 %. The detection of liverworts is approximately 25–30 %, leaf-stem mosses – 40–45 %.

FRAILTY AND NUTRITION: WHAT WE HAVE LEARNED FROM RESEARCH AND CLINICAL PRACTICE ON THE MINI NUTRITIONAL ASSESSMENT
Authors: GUIGOZ Y.
Published: October 2021

In this short communication, we review the relationship between frailty and malnutrition risk in the elderly. Frailty is a term used for elderly at increased risk of adverse outcomes, including disability, falls, hospitalization, need for long-term care, and mortality. The Mini Nutritional Assessment (MNA) was designed and validated in a series of studies to assess nutritional status of elderly, as integral part of the comprehensive geriatric assessment, with a 2-steps screening process; when the MNA-SF classify a person at risk, the full MNA should be completed. The MNA and MNA-SF are sensitive, specific, and accurate in identifying nutrition risk. Increased risk of malnutrition, a common condition in the elderly, is closely associated with many potential contributors of frailty. The maintenance of optimal physical and cognitive performances depends on the early screening of critical conditions to develop preventive targeted interventions; the MNA supports such preventive action.

Published: October 2021

Objective: Sarcopenia, the age-related loss of skeletal muscle mass, is highly prevalent in older adults. The aim of this study was to investigate the effects of the combination of resistance training and multinutrients supplementation (including vitamin D and protein) on muscle mass and physical performance in frail older adults. Methods: This trial was conducted in Japanese frail older adults (n=77), which underwent a standardized protocol of a 3-month physical exercise intervention. The sample population was divided into two groups, according to the adoption (S/Ex: n = 38) or not (Ex: n = 39) of the additional multinutrient supplementation. The outcome measures of interest for the present analyses were the skeletal muscle mass index (SMI) and several physical performance tests. Results: Participants in S/Ex group had significant improvements for the outcome measures, including SMI and maximum walking time (P<0.05), compared to those in Ex group. The prevalence of sarcopenia decreased from 65.7% to 42.9% in S/Ex group, while that in Ex group remained unchanged (68.6% to 68.6%) (relative risk = 1.60, 95% CI: 1.03-2.49). Conclusion: The results of this study suggest that the combination of resistance training and multinutritional supplementation may be more effective at improving muscle mass and walking speed than an intervention only based on resistance training.
Seismic Performance of Precast Columns Connected with Two Different Connection Modes
Authors: Wang Chuanlin
Published: October 2021

The precast reinforced concrete building is made of precast components, which are connected at the joints via reliable connection approaches. Therefore, the study on the stability and reliability of the connections should be conducted to improve the safety and integrity of the precast structure. In this paper, experiments on two connection modes, i.e. corrugated pipe confined with spiral stirrup connection and steel sleeve connection, were carried out. The experimental tests consisted of six specimens, including one cast-in-situ specimen, three precast specimens using steel sleeve connection and two precast specimens using corrugated pipe confined with the spiral stirrup. The influence of artificially unbonded length at the connection joint is also studied. All specimens were tested under low-frequency cyclic repeated loading to analyse their seismic performance under different connection modes. The experimental results showed that the precast columns using the two proposed connections have a similar or even better seismic performance compared with the cast-in-situ column. The installation of proper unbonded treatment on the longitudinal reinforcement in the connection is beneficial in improving the seismic performance of precast columns and the length of 5 times of the longitudinal reinforcement’s diameter is recommended.

Published: October 2021

Extreme conditions will cause the water level of high fill canal segment to change suddenly, which will affect the velocity and pore pressure of the slope. In this paper, numerical method is used to study the influence of water level sudden change on seepage characteristics of high fill canal segment. HyperMesh software is used to establish the finite element model of typical high fill canal segment under complex foundation conditions. Through the combination of secondary development program and fluid-structure coupling calculation method, the fluid structure cou-pling effect of canal under sudden change of water level is analyzed in ABAQUS. The results show that when the water level changes suddenly, the pore pressure below the free water surface and the velocity near the free surface will be greatly affected.

Beethoven jako aktor historyczny. Perspektywa mikrohistoryczna w muzykologii
Authors: Mika Bogumiła
Published: October 2021

The article focuses on issues of microhistory and the usefulness of  this historiographical practice in musicological research. The author begins by presenting the key issues relating to microhistory,  referring extensively to the book What Is Microhistory? by István  M. Szijártó and Sigurður Gylfi Magnússon. She then quotes and briefly  discusses the most significant musicological works which employed  microhistorical strategy. These are Mark Everist’s book Music Drama  at the Paris Odéon, 1824–1828, Tamara Levitz’s Modernist Mysteries:  Perséphone and Peter J. Schmelz’s article “Shostakovich” Fights the  Cold War: Reflections from Great to Small. The main part of the text  is devoted to Mark Ferraguto’s monograph Beethoven 1806. That publication is wholly based on the microhistorical approach, thus open- ing a new perspective in reflection on the instrumental works by the Master from Bonn. Ferraguto analyses Beethoven’s works from 1806  and early 1807 in the context of the people and the instruments for  which they were composed; he also explores the nature of and reasons  for the composer’s retreat from the „heroic phase”, analysing various  aspects of contemporary musical, social and political life in Vienna.  He does so while concentrating on selected, characteristic moments  which define the given opus. Unlike the earlier musicological works based on the microhistorical strategy, Ferraguto’s monograph is not overburdened with detail,  but makes an excellent job of linking contextual issues with analysis  of musical composition. In this way it enriches musicological research  by providing it with a new, interesting dimension.

Authors: Nikolovski S. S. , Bozic N. B. , Fiser Z. Z. , Lazic A. D. , Tijanic J. Z. , Raffay V. I.
Published: October 2021

The Aim: analysis of the influence of dispatcher assistance during cardiopulmonary resuscitation (CPR) of patients with out-of-hospital cardiac arrest (OHCA) in achieving return of spontaneous circulation (ROSC), better survival at the scene, survival to discharge, and 30-day survival.Materials and methods. This study includes epidemiological data on OHCA collected by the study protocol of the European Resuscitation Council's EuReCa_ONE study during the period October 1, 2014 — December 31, 2019. Statistical analysis was performed using SPSS Statistics v26 and GraphPad Prism v8 software packages.Results. This study included 288 patients with OHCA where CPR was provided by bystander. Dispatcher-assisted CPR (DA-CPR) occurred in 56.9% of those patients and ROSC was achieved in 31.3% of cases. Forty-four patients were hospitalized and 16 of those survived until discharge. There was no influence of dispatcher assistance on ROSC, although it resulted in slightly greater risk of the absence of ROSC (OR=1.063). Higher mortality rate to discharge occurred in DA-CPR group (P=0.013). No statistical significance was observed between DA-CPR and non-DA-CPR groups in terms of death at the scene, and 30-day survival. Dispatcher assistance during the initial CPR in hospitalized OHCA patients was a significant predictor of death outcome during hospitalization (P=0.017, OR=5.500).Conclusions. There is no significant association between the presence/absence of dispatcher assistance and ROSC or 30-day survival rate. In contrast, DA-CPR was non-significantly associated with slightly higher odds for the absence of ROSC. DA-CPR was also associated with lower survival-to-discharge rates in hospitalized OHCA patients. The study findings are the base/ground which highlights the need of implementation of existing and development of new guidelines regarding high-quality professional training of EMS dispatchers as well as basic life support education of general population.

Authors: Rautbart S. A. , Tyurin I. N. , Alexandrovskiy A. A. , Kozlov I. A.
Published: October 2021

Aim of the study: to determine the predictive value of central hemodynamic parameters in relation to mortality and evaluate their potential acceptability for goal-directed therapy during days 1-4 of treatment in patients with sepsis.Material and methods. The results of investigation and treatment of 62 patients aged 50.9±2.13 years with abdominal sepsis were analyzed. The patient severity on admission to the intensive care unit was 13 [10-15] on the APACHE II scale, 8 [6.75-9.25] on the SOFA scale. Lethal outcome 15.6±1.4 days after admission occurred in 19 (31%) patients. Central hemodynamic parameters were studied by transpulmonary thermodilution according to the standard technique. Infusions and administration of sympathomimetic drugs were performed according to Sepsis-3 guidelines. Statistical analysis was performed using logistic regression and ROC analysis.Results. The median values of the main circulatory parameters during days 1-4 of sepsis treatment were within normal ranges. Cardiac index, afterload-related cardiac performance, global cardiac ejection fraction and cardiac function index were predictors of mortality at all stages of treatment. However, the first three parameters did not provide either sufficient model quality at the study stages or a stable cutoff value with acceptable sensitivity and specificity. The cardiac function index maintained good model quality (area under the ROC curve 0.708-0.753) and a stable cutoff value (≤5.75 to ≤5.81 min-1) with acceptable and balanced sensitivity and specificity of about 70% at all study stages.Conclusion. The cardiac index, afterload cardiac performance, global cardiac ejection fraction and cardiac function index during days 1-4 of intensive care of sepsis are predictors of lethal outcome. At the same time, only the cardiac function index maintains good model quality and consistent cut-off point value with acceptable sensitivity and specificity at all stages of the study. The feasibility of using the cardiac function index as one of the parameters of goal-directed therapy aimed at cardiovascular function improvement in sepsis needs further investigation.

Published: October 2021

Unified Modeling Language (UML) is widely used standard for models visualization in software industry. Hence, a preparation of IT professionals involves the learning modeling process. Studies of student perception of UML modeling indicate that this process is perceived as quite complex. This paper presents software for validation activity, class and use-case diagrams by XMI representation. To achieve this goal, we researched existing methods and systems. Besides, we analyzed mistake catalogues and Perm State University’s student models to propose a mistake classification and checklist that presents a list of validation to be done. This paper focuses on validation each type of diagram separately, without maintaining consistency between different UML models. However, all these validation modules are combined in one system, which allows to check any of the described types of diagrams.

One of the most common ways documents leak is taking a picture of document displayed on the screen. For investigation of such cases data leakage prevention technologies including screen watermarking are used. The article gives short review on the problem of screen shooting watermarking and the existing research results. A novel approach for watermarking text images displayed on the screen is proposed. The watermark is embedded as slight changes in luminance into the interline spacing of marked text. The watermark is designed to be invisible for human eye but still able to be detected by digital camera. An algorithm for extraction of watermark from the screen photo is presented. The extraction algorithm doesn’t need the original image of document for successful extraction. The experimental results show that the approach is robust against screen-cam attacks, that means that the watermark stays persistent after the process of taking a photo of document displayed on the screen. A criterion for watermark message extraction accuracy without knowledge about the original message is proposed. The criterion represents the probability that the watermark was extracted correctly.
Complete decision procedure for the theory of bounded pointer arithmetic based on quantifier instantiation and SMT
Authors: Sadykov Rafael Faritovich , Mandrykin Mikhail Usamovich
Published: October 2021

The process of developing C programs is quite often prone to errors related to the uses of pointer arithmetic and operations on memory addresses. This promotes a need in developing various tools for automated program verification. One of the techniques frequently employed by those tools is invocation of appropriate decision procedures implemented within existing SMT-solvers. But at the same time both the SMT standard and most existing SMT-solvers lack the relevant logics (combinations of logical theories) for directly and precisely modelling the semantics of pointer operations in C. One of the possible ways to support these logics is to implement them in an SMT solver, but this approach can be time-consuming (as requires modifying the solver’s source code), inflexible (introducing any changes to the theory’s signature or semantics can be unreasonably hard) and limited (every solver has to be supported separately). Another way is to design and implement custom quantifier instantiation strategies. These strategies can be then used to translate formulas in the desired theory combinations to formulas in well-supported decidable logics such as QF_UFLIA. In this paper, we present an instantiation procedure for translating formulas in the theory of bounded pointer arithmetic into the QF_UFLIA logic. We formally proved soundness and completeness of our instantiation procedure in Isabelle/HOL. The paper presents an informal description of this proof of the proposed procedure. The theory of bounded pointer arithmetic itself was formulated based on known errors regarding the correct use of pointer arithmetic operations in industrial code as well as the semantics of these operations specified in the C standard. Similar procedure can also be defined for a practically relevant fragment of the theory of bit vectors (monotone propositional combinations of equalities between bitwise expressions). Our approach is sufficient to obtain efficient decision procedures implemented as Isabelle/HOL proof methods for several decidable logical theories used in C program verification by relying on the existing capabilities of well-known SMT solvers, such as Z3 and proof reconstruction capabilities of the Isabelle/HOL proof assistant.
Identification of transparent, compressed and encrypted data in network traffic
Authors: Getman Aleksandr Igorevich , Ikonnikova Maria Kirillovna
Published: October 2021

The article is dedicated to the problem of classifying network traffic into three categories: transparent, compressed and opaque, preferably in real-time. It begins with the description of the areas where this problem needs to be solved, then proceeds to the existing solutions with their methods, advantages and limitations. As most of the current research is done either in the area of separating traffic into transparent and opaque or into compressed and encrypted, the need arises to combine a subset of existing methods to unite these two problems into one. As later the main mathematical ideas and suggestions that lie behind the ideas used in the research done by other scientists are described, the list of the best performing of them is composed to be combined together and used as the features for the random forest classificator, which will divide the provided traffic into three classes. The best performing of these features are used, the optimal tree parameters are chosen and, what’s more, the initial three class classifier is divided into two sequential ones to save time needed for classifying in case of transparent packets. Then comes the proposition of the new method to classify the whole network flow as one into one of those three classes, the validity of which is confirmed on several examples of the protocols most specific in this area (SSH, SSL). The article concludes with the directions in which this research is to be continued, mostly optimizing it for real-time classification and obtaining more samples of traffic suitable for experiments and demonstrations.

Published: October 2021

This study aimed to describe the imaging aspects of a concha bullosa discovered incidentally by means of cone-beam computed tomography (CBCT) imaging. A female patient underwent a CBCT exam, and a bilateral extensive pneumatization of the middle concha was verified, presenting a larger dimension of the right side and a deviated septum. The patient reported nasal obstruction and loss of smell. The CBCT for covering the maxillofacial region allowed the discovery of this incidental finding, allowing the patient to be referred for appropriate treatment.

Authors: Pilongo Leah Wilfreda RE
Published: October 2021

Research capability in this study is the potential of individuals or staff in the institution to undertake the rigors of effective, efficient, and high-quality research. This study looked into the challenges that professors may face when conducting research. The study was quantitative in nature employing the survey method. The status of the research capacities of faculty from different departments was described using a standardized survey form. From a total of 296 full-time and part-time faculty of the University in 2017, a random sample of 210 respondents was selected with a +/-3.65% margin of error at a 95% confidence interval. This study protocol passed the review of the University’s Research Ethics Committee. The data were analyzed using frequencies, percentages, weighted means, Chi-square, and ANOVA. The findings revealed that the teacher-respondents were relatively young. The results further yielded that the respondents are Moderately Capable of their research capability regarding technical aspects and the major parts of the research paper. As to the other parts of the research paper, they rated themselves as "Capable," as to referencing; teacher respondents rated themselves as "Moderately Capable." Regarding the level of support for the provision of research facilities and resources, respondents rated "Moderately Supportive." When it comes to the levels of difficulty encountered in research writing, respondents perceived it as "Moderately Difficult." Furthermore, results revealed a significant relationship between respondents’ research capability and their age (, sex (, civil status (, highest educational attainment (, number of years in teaching (, and college assignment (.  Respondents' perception of the degree of research support was also significantly associated with their age (, sex (, civil status (, highest educational attainment (, number of years in teaching (, and college assignment (. Finally, there were no significant variances in the respondents’ research capability (F=0.644, p=.853), and level of research assistance (F=0.895, p=.581)when respondents were classified according to their departmental assignment.

Tests in schools can be informative. However, the Department of Education administered a set of examinations like the National Achievement Test which is designed to determine the learner's achievement level, strengths, and weaknesses in five curricular subject areas at the end of the school year. The study intended to look into the relationship between academic performance in Mathematics and NAT results. There has been a purposive universal sampling design. It is purposive because the research is only studying the academic performance in Mathematics, and universal because the subjects of the study are all the grade six pupils of Victoriano D. Tirol Advance Learning Center for four consecutive school years. Documentary analysis was used as to the data of existing records on the academic performance and National Achievement Test results in Mathematics. The association between academic achievement and NAT outcomes in Mathematics was investigated using correlation analysis and one-way analysis of variance (ANOVA). The analyses revealed that there is a significant correlation between the pupil's academic performance and NAT results. Also, there is a significant degree of variance in the student's performance as to National Achievement Test Results in four consecutive school years.
