Published: July 2024

Abstract: Pedestrian paths in Pontianak City are increasingly showing improvement, especially in the city center area where human movement is increasingly busy with various kinds of activities taking place there. Roads as the basic element that forms an area are one of the easiest urban public spaces to observe to understand the characteristics of an area. Actors who travel on the sidewalk face various obstacles and goals they want to achieve during their journey. Walking here is a means to fulfill the need for face-to-face interaction that exists in urban activities. With the uncontrolled growth of urban areas, the development of public spaces for pedestrians is somewhat burdened. Most cities allow citizens to access basic services and needs in walkable areas. Pontianak itself is still dominated by a high number of vehicle users and this is not accompanied by efforts to increase pedestrian comfort. This research aims to determine the obstacles faced by pedestrians, especially in the Pontianak State Polytechnic (Polnep) campus area by measuring the total area that can be passed by pedestrians and assessing pedestrian paths by assessing roads and highways in pedestrian catchment areas. feet at every intersection. . The research method used is a non-probability sampling method, namely an accidental sampling technique to calculate the pedestrian catchment area on the Polnep campus to determine the total pedestrian catchment area that is still comfortable to walk through. By measuring the distance between two nodes by navigating the street layout, urban morphology can impact the measurement of the ratio of route distance to urban distance. The analytical method used in this research is qualitative and quantitative descriptive analysis. Qualitative descriptive analysis is used to describe the results of observations and interpretation of quantitative data presented in tabular form. Meanwhile, the quantitative descriptive analysis method is used to measure or assess user perceptions of walkability quality based on the walkability aspects studied, namely accessibility, comfort, safety and aesthetics. The results and findings of the analysis at the Pontianak State Polytechnic Campus show that Accessibility (A), Security (SAF), Comfort (COM), and Aesthetics or Beauty (AES) have a partial and significant effect on Walkability. The conclusion can be proven through the results of the T test (partial) where the calculated T value for each variable is greater than the T table and the significance value for each variable is <0.05.

Authors: KRYSHOV S.I. , KOTELNIKOV D.E. , GRADOVA O.V.
Published: July 2024

One of the important characteristics of a comfortable environment for a person’s daily stay is the sound insulation of enclosing structures. Insufficient indicators of sound insulation properties of enclosing structures have a negative impact on human health and work activity. To a large extent, both the physical and psychological state of the body is influenced by the level of shock noise. In order to assess these indicators, multiple tests of various floor structures were carried out to ensure that the index of the reduced shock noise level meets the current regulatory requirements. Various variants of structural solutions of overlaps between rooms in buildings of various purposes, which showed the worst values of the indices of the reduced shock noise level, are considered. The analysis of solutions and research presented in various reference and scientific materials and publications of previous years has been carried out. The dependence of the indices of the reduced level of shock noise of the ceilings on the applied design solutions and test conditions is analyzed. The composition of the floor construction layers is described in detail according to the information provided in the design and working documentation for each object of research. Graphs of the relative position of frequency characteristics and estimated spectra of the reduced level of shock noise under overlap for each considered structure are presented.
Application of the Moisture Potential Theory in Assessing the Heat and Moisture Regime of Building Envelopes
Authors: ZUBAREV K.P.
Published: July 2024

The review of existing mathematical models for humidity conditions was carried out. Methods giving an opportunity to calculate moisture transfer in the sorption zone of humidification and in the supersorption zone are described. The features of calculating moisture distribution using the theory of moisture potential are shown. The new discrete-continuous method for calculating the moisture state of a fence is proposed, which makes it possible to determine the unsteady-state moisture regime using an analytical expression without using various numerical methods. Two formulas for a single-layer and a multi-layer building envelope are derived. The formula allows us to determine the distribution of moisture potential in various sections of building envelopes. The effectiveness of the method is proven by comparing the results obtained with calculations using non-stationary and engineering quasi-stationary calculation methods. The humidity regime of a single-layer enclosing structure in the city of Moscow made of aerated concrete blocks, as well as a two-layer enclosing structure with a clay brick base and silicate brick cladding was calculated. It is shown that the calculation results using the proposed method are both quantitatively and qualitatively close to the distribution obtained using the non-stationary calculation method for both single-layer and multi-layer enclosing structures. The method is recommended for use in engineering work, because it gives a possibility to take into account the inertia of moisture in the building envelope.
EU Medical Device Regulation – The Level of Convergence and Impact on Regulatory Complexity
Authors: Gavrilović Jankovič Nika , Nikolić Bruno
Published: July 2024

Medical Device Regulation (MDR) entered into force in 2017 and became applicable in 2021. In the context of Europeanization and the European Union (EU) multilevel governance system, regulations are used as a means of unification. EU has gradually increased the degree of convergence in medical devices, even though medical devices pertain to the health sector, which is within the Member States’ competence. Despite MDR being a regulation, its preamble states that its aim is to harmonize rules for the placing on the market and use of medical devices on the EU market. This article analyzes the level of convergence introduced by the MDR and its impact on regulatory complexity. Our findings demonstrate that many relevant elements, such as mandatory CE marking, reached the level of unification, whereas some that are still to become legally effective, such as the European database on medical devices (EUDAMED), went further and reached the highest level – supranational and integral joint administrative capacities. Unlike the expected inverse correlation between EU convergence and regulatory complexity, our findings revealed that due to delays in bringing into effect certain unifying elements, de facto, MDR introduced additional constraints compared to the previous Medical Device Directive (MDD) framework. This leads to the main finding of this research, which is that the MDR convergence increase has led to a conflicting outcome – an increase in regulatory complexity.

Authors: Kozlov R. S. , Kuzmenkov A. Y. , Vinogradova A. G.
Published: July 2024

The growth and spread of antimicrobial resistance (AMR) is one of the main threats to the healthcare system. Currently, along with the development of new antimicrobial drugs (AMPs) the basic approach to countering the spread of AMR is the rational use of existing medicines. Selection of the optimal drug taking into account its activity, doses, frequency and route of administration are the basis of rational antimicrobial therapy. However, due to widespread availability of AMR, availability of up-to-date information on activity of AMP is extremely important. Therefore, monitoring of antibiotic resistance is a key activity to ensure providing the evidence base on which antimicrobial formularies should be drawn up drugs and treatment protocols. In the solution of these problems in the Russian Federation active role plaies the Methodological Verification Center on Antimicrobial Resistance – Reference center for clinical pharmacology, created on the basis of the Research Institute of Antimicrobial Chemotherapy of the Smolensk State Medical University of the Ministry of Health of Russian Federation.

In this case, the price of the food has been determined, and the buyer only needs to mention the name of the food to be ordered and the seller determines the selling price. There is a case where the price of the food is not specified, and the buyer needs to mention how much money to order. Proving that the seller provides several payment methods, which can be scanned and cash. And some sellers replace the change with two candies because there is not enough money back.
Aritmatika sosial adalah materi matematika yang penting dalam peningkatan ilmu pengetahuan karena digunakan dalam kehidupan sehari-hari di bidang ekonomi. Aritmatika sosial bertujuan untuk memudahkan proses transaksi antar penjual dan pembeli, dan meminimalisir adanya penipuan dan korupsi dari suatu transaksi. Metode yang digunakan dalam penelitian ini adalah metode kualitatif deskriptif yang mengambil subjek penelitian dari hasil pengamatan di lima pedagang sekitar kampus. Dari hasil wawancara tersebut, terdapat beberapa kasus dengan implementasi aritmatika sosial yang berbeda. Berdasarkan hasil penelitian, maka dapat disimpulkan bahwa implementasi prinsip aritmatika sosial dalam transaksi jual beli pedagang terdapat interaksi antara penjual dan pembeli yakni transaksi jual beli. Pada kasus tersebut harga dari makanannya sudah ditentukan, dan pembeli hanya perlu menyebutkan nama makanan yang hendak dipesan dan penjual yang menentukan harga jualnya. Terdapat kasus tersebut harga dari makanannya tidak ditentukan, dan pembeli perlu menyebutkan berapa nominal uang untuk memesan. Membuktikan bahwa penjual menyediakan beberapa metode pembayaran, yaitu bisa dengan scan dan cash. Dan terdapat juga penjual yang menggantikan kembaliannya dengan dua buah permen karena tidak adanya uang kembali yang cukup.

Self-concept of different categories of students. This difference becomes an open secret that students have from a young age and can influence students' critical thinking in mathematics as they solve mathematical problems from within their self-concept. designed to assess their critical thinking ability in solving problems according to their high, average, and low math self-concepts. The research method used is exploratory with a qualitative descriptive approach. The study was conducted with a total of 16 students of SMP Islamic Al Mursidia Grade VIII A. Six students were enrolled as subjects in this study: two students with high self-esteem in mathematics, two students with medium self-esteem in mathematics, and two students with low self-esteem in mathematics. The research was conducted through questionnaires, tests, and interviews. Through data reduction, data presentation, and final stages through technical and temporal triad. The study revealed that two students with high self-concepts, one with a moderately critical self-concept, one with a very critical self-concept, and one with a low self-concept. At a serious enough level, the student is not important.
Konsep diri siswa dengan kategori yang berbeda-beda.
