THE METHOD OF BOUNDED CONSTRUCTIONS OF LOGICAL CLASSIFICATION TREES IN THE PROBLEM OF DISCRETE OBJECTS CLASSIFICATION
Authors:   Uzhhorod National University, Uzhhorod, Ukraine, Povkhan I. F.
Published: June 2021

The problem of constructing a model of logical classification trees based on a limited method of selecting elementary features for geological data arrays is considered. A method for approximating an array of real data with a set of elementary features with a fixed criterion for stopping the branching procedure at the stage of constructing a classification tree is proposed. This approach allows to ensure the necessary accuracy of the model, reduce its structural complexity, and achieve the necessary performance indicators. A limited method for constructing classification trees has been developed, which is aimed at completing only those paths (tiers) of the classification tree structure where there are the greatest number of errors (of all types) of classification. This approach to synthesizing the recognition model makes it possible to effectively regulate the complexity (accuracy) of the classification tree model that is being built, and it is advisable to use it in situations with restrictions on the hardware resources of the information system, restrictions on the accuracy and structural complexity of the model, restrictions on the structure, sequence and depth of recognition of the training sample data array. The limited scheme of synthesis of classification trees allows to build models almost 20 % faster. The constructed logical classification tree will accurately classify (recognize) the entire training sample that the model is based on, will have a minimal structure (structural complexity), and will consist of components – sets of elementary features as design vertices, tree attributes. Based on the proposed modification of the elementary feature selection method, software has been developed that allows working with a set of different types of applied problems. An approach to synthesizing new recognition models based on a limited logic tree scheme and selecting pre-pruning parameters is proposed. In other words, an effective scheme for recognizing discrete objects has been developed based on step-by-step evaluation and selection of sets of attributes (generalized features) based on selected paths in the classification tree structure at each stage of scheme synthesis.

Published: June 2021

O debate sobre a diversidade de gênero nas empresas é algo cada vez mais discutido na sociedade, as próprias companhias enxergam como uma estratégia de negócio. Baseado nessas informações, buscou-se dados da distribuição percentual entre homens e mulheres na direção executiva das empresas listadas na B3, pertencentes aos segmentos ligados a Governança Corporativa, no ano de 2019. O objetivo deste trabalho é apontar a representatividade das mulheres no cargo de diretora executiva das empresas que seguem padrões de governança altamente diferenciados. Realizou-se uma pesquisa bibliográfica, onde buscou-se o conhecimento de autores renomados no assunto. Também foi realizado uma pesquisa do tipo descritiva, conduzida por meio de análise documental e uma abordagem quantitativa em amostra de 175 empresas. Levantou-se através do sítio eletrônico, disponibilizado pelas empresas, a quantidade de diretores e diretoras executivos. Considerou-se todo o corpo da diretoria executiva, incluindo cargos com a denominação de Presidente e Vice-Presidente. Realizou-se uma análise por segmento de governança e por setor de atuação. O resultado obtido entre os segmentos foi homogêneo. Porém, mesmo as empresas que possuem um padrão de governança diferenciado, precisam investir e ganhar maturidade sobre o tema diversidade de gênero. Os executivos precisam estar empenhados em igualizar essa lacuna existente entre homens e mulheres.

ON THE RELATIONSHIP BETWEEN ADMINISTRATIVE JUDICIAL PROCEDURE AND ADMINISTRATIVE PROCEDURE
Authors: OPALEV R.O.
Published: June 2021

The article contains an analysis of topical issues of administrative judicial procedure and administrative procedure. The author substantiates the conclusion about self-sufficiency of law of administrative judicial procedure and proposes directions for its further development. This development is associated with the adoption of legislation on the administrative procedure in Russia. This step can resolve a number of conceptual issues: 1) elimination of excessive preliminary judicial control over activities of the executive branch, the use of preliminary judicial control only where it is needed; 2) optimal regulation of pre-trial and judicial proof, as well as the procedure for reimbursement of legal costs; 3) forming of subject of administrative dispute prior to initiation of judicial procedure, which subsequently makes it possible to clearly delineate procedural rights and obligations of the court and the parties of administrative dispute. As a result, it is concluded that the optimal coordination of legal regulation of administrative procedure and legal regulation of administrative judicial procedure should provide the most effective protection of the rights of individuals and legal entities arising from public legal relations. The new legal regulation should not be aimed at restriction of procedural rights (for example, by introducing a mandatory pretrial procedure for resolving of all types of administrative disputes).

Authors:   , Daigle Kelly
Published: June 2021

During my social work practice with vulnerable populations, I have found that many clients and families I work with have experienced trauma in various forms. This is no less true in our current reality of concurrent health crisis: the opioid epidemic and the COVID-19 pandemic. My practicum at CAST provided me with numerous opportunities to observe, evaluate and provide trauma-informed practice through direct and indirect learning and training opportunities. My learning goals were to learn clinical practice skills for individual practice, to learn how to provide quality trauma-informed practice, and to develop a professional practice framework consistent with the British Columbia College of Social Workers (BCASW) Code of Ethics. This report discusses my practicum experiences, implications for personal practice such as the need for ongoing, effective self-care, and concludes with several recommendations for social work practice.
Some Brief Notes on Kai Māori
Authors: Rangiwai Byron
Published: June 2021

Food is a signifier of identity and status (Hayden, 1998, 2009; Hayden & Villeneuve, 2011; Neill et al., 2015). In traditional times, Māori consumed a range of hunted, gathered, and cultivated foods (Royal & Kaka-Scott, 2013). As a result of this diet, non-infectious diseases were low among Māori due to foods with higher levels of protective chemicals and nutrients (Cambie & Fergusson, 2003).
Review of the early reports of the epidemiological characteristics of the B.1.1.7 variant of SARS-CoV-2 and its spread worldwide
Authors: Kim Yeonju , Kim Eun-Jin , Lee Sang-Won , Kwon Donghyok
Published: June 2021

The variant B.1.1.7 of SARS-CoV-2, the RNA virus causing the pandemic more than a year worldwide, was reported from UK in late Dec, 2020. It was reported that mortality increases by 65% and transmissibility increases by 70%, which may result in an increase of reproduction number to 1.13-1.55 from 0.75-0.85. To analyze the global increasing trend of the variant B.1.1.7, we extracted results of B.1.1.7 from GISAID on May 11 and May 12, 2021, and conducted a dose-response regression. It took 47 days to reach 20% and 121 days to reach 50% among the sequence submitted from UK. In Korea, cases of B.1.1.7 have increased since the first report of three cases on Dec 28 2020. Positive rate of B.1.1.7 in Korea was 21.6% in the week from May 9 to May 15, 2021. Detection rate of the variants is expected to increase further and new variants of SARS-CoV-2 are emerging, so a close monitoring and control would be maintained for months.

Mangrove Forest Restoration by Fisheries Communities in Lampung Bay: A study based on perceptions, willingness to pay, and management strategy
Authors: Firdaus Maulana , Hatanaka Katsumori , Saville Ramadhona
Published: June 2021

Mangroves provide benefits and various services to local communities living along coastal areas, particularly fishery communities. Fishery community perceptions are significant in determining attitudes towards improving mangrove conditions, which can also be addressed through restoration activities. This research was conducted to analyze fisheries communities perceptions, willingness to pay (WTP) for mangroves restoration, and mangrove forest management strategies. Field surveys were conducted from July-August 2019 and February-March 2020. Primary data were collected from respondents in four regions (Kalianda Regency, South Lampung Regency, Bandar Lampung City, and Pesawaran Regency) in Lampung Province, Indonesia, which consist of fishers, shrimp farmers, crab and wood seekers, and finfish farmers. The respondents were 193 people, and four experts were involved in the policy scenario analysis. Results revealed a gap in the value of WTP among fishery community groups, in which the average value for fishers is lower than shrimp farmers. The years of formal education significantly influenced the WTP for mangrove restoration. Based on the scenario analysis, scenario 01 become a priority strategy, where four policies (P1 = Mangrove ecotourism development in Lampung Bay; P2 = Mangrove knowledge education and training on processing mangrove based products; P3 = Restoration and conservation of mangrove forests; and P4 = Community-based management for mangrove forests utilization) show high likelihoods to be simultaneously implemented for mangroves management, with mangrove ecotourism policy as the most decisive policy. For future research, other explanatory variables can be added, such as information on family member characteristics, and to develop a bottom-up policy scenario by identifying and involving the role of the local community.

Authors: Jesulana Oluwasegun Samuel , Olowe Victor Idowu , Adeyemi Olusegun Raphael , Adejuyigbe Christopher Olu
Published: June 2021

Organic soybean is presently less than 0.1% of total world production partly because of inappropriate fertiliser regime on degraded tropical soils. Therefore, two field trials were carried out during the late cropping seasons (June – November) of 2017 and 2018 to evaluate the agronomic performance of three soybean varieties: TGx 1448-2E, TGx 1835-10E and TGx 1989-9F as affected by foliar organic fertilisers: Arati Baja, Arati Nawoz, DI Grow, and soil applied organic fertiliser (Aleshinloye Grade B), and the control. The experimental design was Randomised Complete Block Design in a 3 × 5 factorial arrangement with three replications. Data were collected on yield attributes and seed yield of soybeans. Significant varietal difference (P < 0.05) in both years was recorded for number and weight of pods and seeds per plant, 100 seed weight, harvest index, and grain yield, except number of seeds per plant in 2018. Fertiliser × Variety interaction effect significantly (P < 0.05) affected above-ground plant weight and pod weight per plant in both years. On average, application of organic fertilisers resulted in grain yield (1.30–2.28 t/ha) comparable with Nigeria’s (0.97 t/ha) and Africa’s (1.37 t/ha) but lower than the world’s (2.85 t/ha) average values. The three foliar fertilisers and soil applied organic fertiliser enhanced seed yield of soybeans and are therefore recommended for soybean cultivation in the tropics.

The Study of Students’ Talents and Skills as the Starting Point in Narrowing the Skills Gap of Human Resources in the Tourism Sector
Authors: Skalska Teresa , Rękawek Anna
Published: June 2021

Objective: The article refers to the measurement of natural talents and skills of students in an internationalised environment and possible use of empirical research to modify university curricula. The article aims to determine how to design and implement skills models to increase education efficiency and to adapt the curriculum to the labour market expectations.

Methodology: The evaluation was based on three empirical surveys conducted among students of a highly internationalised university: the Gallup test measuring natural talents, the Filipowicz test (measuring skills) and a poll among students, diagnosing their expectations as to student apprenticeships and traineeships.

Findings: Using the aforementioned tools allowed to identify strengths of university students in tourism programmes and to indicate areas for improvement during education.

Value Added: The conclusions drawn from the survey allowed to confront students’ skills with employers’ expectations and to develop student support methods, e.g. through appropriate modifications of curricula and traineeship programmes. University courses were extended to include modules reinforcing students’ enterprise, the management of individual potential, cross-cultural communication and negotiating skills.

Recommendations: Such survey enables the creation of a talent bank among students where their talents – reinforced with the knowledge and skills acquired at university – will help develop their strengths and can be particularly useful in selected posts.
Nesting habitat selection and challenges of conservation of the vulnerable Lesser Adjutant Leptoptilos javanicus (Horsfield, 1821) in the Chitwan National Park, Nepal
Authors: Bhattarai Bishnu Prasad , Adhikari Jagan Nath , Rijal Manukala
Published: June 2021

The nesting ecology and conservation threats of the Lesser Adjutant (Leptoptilos javanicus) were studied in the Chitwan National Park, Nepal. We located nine nesting colonies during the nesting season. The number of nests was highly positively correlated with tree height, diameter at breast height and canopy cover. The uppermost canopy of the trees was the most preferred nesting place. Storks preferred to nest in compact colonies on large, widely branched trees with thin foliage cover, such as Bombax ceiba, and also nearby the foraging grounds such as wetlands and grasslands. Storks mostly preferred to nest in Bombax ceiba, but if this tree was not available, they nested in other trees, such as Shorea robusta, Ficus racemosa and Terminalia alata. During the breeding season, 180 adults, 76 nests and 88 chicks were recorded, where the highest number of chicks was recorded near the Sauraha area of the Chitwan National Park. Most of the colonies were far from human settlements, which suggest that human disturbance could be the major determinant of nesting habitat selection in this area. The wetlands nearby human settlements are either overexploited in terms of mass collection of the storks` prey species by people or disturbed highly due to presence of a large number of people. These empirical findings suggest that conservation of Lesser Adjutant mainly rely on the protection of mature Bombax ceiba trees and the reduction of human disturbance and of the collection of stork prey animals from foraging areas.

Authors: Spiliotis Antonios E. , Gäbelein Gereon , Holländer Sebastian , Scherber Philipp-Robert , Glanemann Matthias , Patel Bijendra
Published: June 2021

Background

Guidelines have reported that although microwave ablation (MWA) has potential advantages over radiofrequency ablation (RFA), superiority in efficacy and safety remain unclear. Aim of the study is to compare MWA with RFA in the treatment of liver cancer.

Methods

Meta-analysis was conducted according to the PRISMA guidelines for studies published from 2010 onwards. A random-effects model was used for the meta-analyses. Complete ablation (CA), local tumor progression (LTP), intrahepatic distant recurrence (IDR), and complications were analyzed.

Results

Four randomized trials and 11 observational studies with a total of 2,169 patients met the inclusion criteria. Although overall analysis showed no significant difference in LTP between MWA and RFA, subgroup analysis including randomized trials for patients with hepatocellular cancer (HCC) demonstrated statistically decreased rates of LTP in favor of MWA (OR, 0.40; 95% CI, 0.18–0.92; p = 0.03). No significant differences were found between the two procedures in CA, IDR, complications, and tumor diameter less or larger than 3 cm.

Conclusions

MWA showed promising results and demonstrated better oncological outcomes in terms of LTP compared to RFA in patients with HCC. MWA can be utilized as the ablation method of choice in patients with HCC.

The number of patients with diabetes mellitus in the Russian Federation on January 1, 2019 is more than 4.5 million people, which is 3.12% of the population of the Russian Federation. Metabolic disorders in diabetes mellitus cause physicochemical changes, including a violation of acid-base balance (pH). Aim. To study the effect of diabetes mellitus and ocular prosthetics on the acid-base balance of the prosthetic cavity. Materials and methods. From 2018 to 2021 - 185 patients of both sexes from 21 to 80 years old (57.73±17.34 years old) were examined. 47 patients using an eye prosthesis and without diabetes mellitus (group I); 93 patients using an eye prosthesis with diabetes (group II), which were divided into two subgroups depending on the level of glycated hemoglobin (HbA1c): II-a subgroup - 47 patients with HbA1c up to 7.5%, II-b group – 46 patients with HbA1c more than 7.5%; 45 patients, without an eye prosthesis and without diabetes mellitus (group III). Results. In patients with an ocular prosthesis and without diabetes, a shift in pH to the side of acidosis was observed. In patients with an ocular prosthesis and with diabetes mellitus, the greatest shift in the pH of the conjunctival cavity to the side of acidosis, depending on the level of HbA1c (8-8.5 – in 25.8% of cases, 9-9.5 – in 43% of cases, and <10 – in 31.2% of cases). Conclusions. The presence of an ocular prosthesis in the conjunctival cavity leads to a shift in pH to the side of the alkaline side. The progression of the pH shift to the side of acidosis directly depends on the HbA1c level in patients, and the combination of two factors (the use of an ocular prosthesis in the conjunctival cavity and the presence of diabetes in the anamnesis) leads to an aggressive shift in the pH of the conjunctival cavity to the side of acidosis. Key words: acid-base balance, ocular prosthesis, diabetes mellitus.

Purpose. To evaluate the efficacy and safety of femtolaser-assisted phacoemulsification in glaucomatous eyes in the long-term follow-up. Materials and methods. A retrospective analysis of the results of the surgical treatment of patients with combined cataract and glaucoma pathology was analyzed. The patients were divided into groups depending on the method of surgical intervention: 1) phacoemulsification with femtolaser support (26 eyes, 23 patients); 2) phacoemulsification (36 eyes, 30 patients); Results. Before surgery, there were no statistically significant differences in IOP and corneal hysteresis (СН) between groups 1 and 2. The mean values of IOP cc, IOP g and СН of group 1 before surgery were 22.7±6.1 mm Hg, 20.9±6.9 mm Hg, 8.5±1.6 mm Hg; 2 group – 22.9±8.7 mm Hg, 21.6±8.9 mm Hg, 8.9±1.6 mm Hg respectively. Average values of IOP cc, IOP g and CН 5 years after the surgical treatment in group 1 were 15.3±1.2 mm Hg, 14.4±3.4 mm Hg, 9.6±4.2 mm Hg; in group 2 – 18.0±4.2 mm Hg, 16.1±4.2 mm Hg, 8.8±2.2 mm Hg respectively. In both groups, stabilization of IOP and CH indices was noted, which remained throughout the entire observation period, which shows the normalization of the biomechanical properties of the corneoscleral membrane of the eye in the long-term postoperative period. Conclusion. Femtolaser accompaniment of phacoemulsification is an effective and safe method of cataract surgery for combined pathology. Key words: femtolaser, cataract, glaucoma, phacoemulsification.

Purpose. Create a summary classification of exophoria. To propose an optimal algorithm for optometric and surgical methods of treatment. A modern view of the problem. It is optimal to subdivide exophoria according to the state of the vergent-duction balance into divergence excess, basic exophoria, convergence insufficiency, divergence pseudo-excess, lateral gaze incomitance. By the degree of compensation for compensated, subcompensated, uncompensated, decompensated. In combination with alphabetic pattern for exophoria without pattern, exophoria in combination with horizontal type A pattern, exophoria in combination with vertical type A pattern, exophoria in combination with horizontal type V pattern, exophoria in combination with vertical type V pattern. Features of optimal optical and prismatic correction depend on the state of the vergent-duction balance. In cases of exophoria without pattern surgical treatment is carried out during the transition from a state of subcompensation to non-compensation. In case of exophoria with horizontal-type alphabetical pattern, combined horizontal-transpositional surgery is optimal: elimination of exophoria, the protocol is based on the amount of deviation in the direct gaze position; elimination of the pattern, the protocol is based on vertical transposition of muscles of horizontal action. In cases of exophoria with vertical-type pattern, it is necessary to perform staged vertical-horizontal surgery: stage 1 – elimination of vertical heterotropy in adduction; stage 2 – elimination of exophoria (the protocol is based on the amount of deviation in the direct gaze position). Conclusions. The treatment protocol should be based on a reliably diagnosed diagnosis and consists at the pre-surgical stage in the optimal optical and prismatic correction, the appointment of orthopto-diplopto-prismatic treatment. The effectiveness of treatment is assessed by the dynamics of the disease: the magnitude of exodeviation and the stage of compensation. The protocol of surgical treatment must be reasonable and timely. Key words: exophoria, divergence excess, convergence insufficiency, basic exotropia, lateral gaze incomitance, alphabet pattern.

Purpose. To analyze the postoperative result of visual and refractive functions in patients with extremely high myopia, taking into account the initial changes in the macular zone and rather complex calculations of the optical power of negative aphakic IOLs. Materials and methods. On the basis of S. Fyodorov Eye Microsurgery Federal State Institution, Moscow, 57 negative aphakic IOLs were implanted over the past 3 years, which amounted to an average of 0.14% of the total number of implanted IOLs. All patients who were supposed to have a negative IOL implanted in the list of preoperative diagnostics included OCT of the posterior segment of the eye and ultrasound scanning to assess the existing degenerative changes in the posterior segment of the eye. Results. The average visual acuity before surgery in the group of emmetropes was ±0.32, and in patients with extremely high myopia, visual acuity did not exceed 0.1 in 2018, 0.23 in 2019, and 0.22 in 2020. In the operated extreme myopes, the mean BCVA increased to ±0.43, which is slightly lower than the average BCVA of the operated emmetropes during the same period (±0.58). None of the patients had intraoperative complications. Posterior capsule opacification was noted in 20 cases (35%) within 12-14 months after cataract surgery, which is several times higher in comparison with emmetropes, where posterior capsule opacification is observed in 8-15%, depending on the IOL model. Conclusion. This group of patients requires a particularly careful preoperative diagnosis, as well as surgery with increased caution due to the presence of concomitant pathology of the posterior segment of the eye. The experience of using negative IOLs for cataract in patients with extremely high myopia has shown good results in relation to postoperative visual and refractive functions, despite the fact that BCVA in extreme myopes after surgery is limited by the initial changes in the macular zone. Key words: negative aphakic IOLs, extremely high myopia, complicated cataract.
