Purpose: The risk of epiphora after medial maxillectomy with lacrimal duct transection is difficult to assess. The data available in the literature are inconclusive due to various operating techniques used by the authors of medical publications, different additional procedures aimed at improving tear drainage after maxillectomy, and a variety of lacrimal duct patency assessment techniques. The aim of our work was to assess the anatomical and functional patency of lacrimal ducts after medial maxillectomy without performing additional procedures to improve tear drainage as well as comparison of the results obtained with different assessment tests. Materials and methods: 21 patients who underwent medial maxillectomy in the years 2016–2019 were assessed for discomfort and epiphora based on patients’ own reports and basic clinical examination, lacrimal duct rinse test, the Munk score, and a modified endoscopic Jones I test. Results: Gradually increasing the sensitivity of the assessment method resulted in an increase in the number of patients with potential tear drainage disorders, starting from 0% in the rinsing test, 4.8% self-reported tearing complaints, 14.3% Munk score, and 19% modified endoscopic Jones I test. Conclusions: The study results revealed that a small fraction of patients tend to report epiphora as a consequence of medial maxillectomy themselves. Subtle functional disorders, which are not particularly bothersome to patients, are more common. More sensitive lacrimal duct patency tests reveal more cases of tear drainage disorders. The results of studies assessing the incidence of epiphora after medial maxillectomy appear to depend on the type of test used.

Abstract A method to scale and deform a trimmed NURBS surface while holding the shape and size of specific features (trimming curves) unchanged is presented. The new surface is formed by scaling the given surface according to the scaling requirement first; and then attaching the (original) features to the scaled NURBS surface at appropriate locations. The attaching process requires several geometric operations and constrained free-form surface deformation. The resulting surface has the same features as the original surface and same boundary curves as the scaled surface while reflecting the shape and curvature distribution of the scaled surface. This is achieved by minimizing a shape-preserving objective function which covers all the factors in the deformation process such as bending, stretching and spring effects. The resulting surface maintains a NURBS representation and, hence, is compatible with most of the current data-exchange standards. Test results on several car parts with trimming curves are included. The, quality of the resulting surfaces is examined using the highlight line model.

At the present stage, pedagogical tests are one of the most accessible and developed methods for assessing students' knowledge. Evaluation of the results of global research on testing problems showed that the developers of test items pay special attention to the form and their standardization, the processing of test results and the interpretation of the data obtained, methods of automatic test formation. The goal is to study the possibility of using testing to assess the formation of students' competencies. Materials and methods. Theoretical: a review of psychological and pedagogical literature on research issues, analysis, synthesis, generalization, systematization. Results. Testing characterizes a number of properties, the main of which is the objectivity of the assessment of results, the definition of "gaps" in knowledge. The result of testing is obtaining objective information about the quality of knowledge and skills, determining the sections that are the worst learned by the students. All of the above makes it possible to adjust the course of training. Test control can be external, when the subjects are offered a dichotometric range, which contains both completed and unfulfilled tasks on a wide range of issues. During the testing process, students have the opportunity to independently identify gaps in their own knowledge. The study confirms the possibility of using testing in assessing the formation of students' competencies and ultimately provides an increase in the level of knowledge. Conclusion. At the present stage, the introduction of tests into educational practice is an inevitable process, therefore, efforts should be directed to the development of a theoretical platform for the testing system, which will entail an increase in the efficiency of using tests as a form of control.

Test Serum

A new serologic test for antibodies to Toxoplasma is described, which is based upon inhibition of specific staining with fluorescent antibody. In performing the test, a mixture of the test serum and known fluorescein-labelled antiserum is added to a dried smear of toxoplasms for 1 hour at 37°C. The smear is then rinsed and examined with a fluorescence microscope. Reduction in the brightness of fluorescence, as compared to that of a negative control slide, indicates the presence of antibody in the test serum. A comparison of the results of this test with those of the methylene blue dye test showed a strong parallelism between the two sets of results. On the other hand, the complement-fixation test for toxoplasmosis did not yield nearly as many positives as the inhibition test. The specificity of the new test was studied by comparing it with dye test results and clinical histories in human patients, and by testing a group of animals immunized with a variety of non-Toxoplasma antigens. No evidence of cross-reactions was obtained in the latter series. Some advantages and disadvantages of the inhibition test are discussed.

Introduction. Currently, there is no uniform methodology for assessing student competencies and learning outcomes in Russia. Educational organizations develop these methodologies independently. There are no uniform grade allocation criteria, and there is confusion about the concepts of “indicators” and “evaluation criteria” that challenges the assessment of the quality of educational activities and triggers complaints about biased assessments. In this regard, there is a need to set reasonable rules for evaluating learning outcomes. Materials and methods. The author made a contribution in the development of a methodology for evaluating learning outcomes at NRU MGSU. A comparative analysis of the assessment methods described in the publications made by different authors was carried out to identify the strengths and weaknesses of this methodology. The proposed methodology is compared with Bloom’s taxonomy. Results. The analysis has shown that currently used assessment methods are far from being perfect, and a number of problems of their development have been identified. Principles of selecting indicators and evaluation criteria are proposed on the basis of the analysis performed by the author. It is advisable to use such learning outcomes, as knowledge and skills, as assessment indicators. A system of knowledge and skills assessment criteria characterizing their amount and quality is proposed. Conclusions. The proposed assessment method has advantages and disadvantages. Its advantages include clarity and flexibility of the criteria that ensure a comprehensive assessment of knowledge and skills. The disadvantages of the methodology are the complexity of the criterial system and disregard for any personal features of a student in the process of evaluation.

High demand for clean water in Banjarmasin requires PDAM Bandarmasih to do some developments, but its efforts are hindered by the water quality of raw water to be processed. It is therefore necessary to conduct a study on the water quality of raw water sources of PDAM Bandarmasih, especially during dry season. Water quality testing was carried out by performing direct experiments in the field and in the laboratory with 7 criteria including water temperature, electrical conductivity, total dissolved solids, pH, turbidity, salinity and dissolved oxygen that were compared with the criteria of water class B (water that can be used as the raw water for drinking water), on the basis of the Regulation of the Minister of Health of the Indonesia Republic No. 492/Menkes/PER/IV/2010. Based on the analyses of water quality in the field and in the laboratory from 4 intakes namely Sungai Tabuk, Pematang Panjang, Sungai Lulut and Sungai Bilu, and the comparison of the results with the test results of water quality of the samples from PDAM taken in dry season, indicated that the amount of salt content (salinity) in two intakes, Sungai Lulut and Sungai Bilu was so high that the production of clean water from both intakes was stopped temporarily during the dry season. The service for clean water was therefore provided only at the intakes of Sungai Tabuk and Pematang Panjang during dry season, resulting in some reduction in distribution to some areas in Banjarmasin.

The article is focused on studies of domestic and foreign scientists concerning the aesthetic properties of landscapes. Different methodological approaches of analysis and description of the visual quality of landscapes are presented. The world experience in the application of methods to assess the landscape attractiveness of territories when arranging of recreational zones was studied. The analysis of different types of landscapes, their aesthetic advantages and disadvantages, as well as characteristics from the point of view of the arrangements of recreational areas was carried out. The relation between natural features of the area, its aesthetic parameters and the demand degree among vacationers was revealed. The features of the natural framework of the Belgorod region were determined; characteristic of regional landscape features, affecting the emotional perception of landscapes (chalk outcrops, wetlands of riverine lands, etc.) were identified. The assessment of the aesthetic attractiveness of landscapes is carried out using the territories of the Valuysky municipal district as an example. The localization of the areas with the greatest aesthetic attractiveness was determined and the promising territories for the development of recreational zones were identified. The compositional structure of the gully-like landscape was analyzed as one of the characteristic features for this region as a whole. Recommendations on the application of the assessment method for aesthetic of landscape attractiveness, taking into account regional characteristics the Belgorod region as an example were proposed.

Background. The problem of forecasting nonlinear nonstationary processes presented in the form of time series is very relevant, since such series can describe dynamics of the processes in both technical and economic systems. To establish the best model, various metrics are used to assess the quality of forecasts, such as R^2, RMSE, MAE, MAPE. However, in many tasks, when optimizing the model according to the selected criterion, the model becomes worse in relation to another criterion. Therefore it is important to understand which metric must be used to optimize and assess the quality of the forecast in the given task. Objective. The aim of the paper is to develop a criteria base for assessing forecasts of nonlinear nonstationary processes, as well as an approach to choosing a metric in accordance to the specificity of the set forecasting problem. Methods. The paper presents a comparative analysis of the basic metrics for the regression problem, their theoretical and practical meaning, advantages and disadvantages in various cases. New approaches are proposed based on the results of the analysis. Results. Based on the analysis of the selected data, it is shown that by optimizing the model according to the selected criterion, the model becomes worse in relation to another criterion. A criterion basis for assessing forecasts of nonlinear nonstationary processes has been formed, as well as an approach to the selection of a quality criterion in accordance with the specifics of the set forecasting problem. To minimize an absolute error, the RMSE (MSE, R^2) and MAE metrics are analysed and recommended, depending on the need to work with outliers. The RMSLE metric is proposed for solving the problems of minimizing the relative metric, for solving the shown problems of the MAPE metric for this class of problems.  Conclusions. The paper shows the importance of choosing a metric that must be used to optimize and assess the quality of the forecasts in the given task. The obtained criterion base and approach can be used in further research to solve practical prob- lems in modelling and forecasting nonlinear nonstationary processes and to develop new methods or general method for solving such problems.
