Abstract. An analysis of modern capital construction state shows that the material and technical base of the construction industry does not allow the production of effective building materials and products in the required quantity without due consideration of the economic burden on the environment, and now significant financial costs are required to restore the ecological balance of the natural zone. Power plant fly ash is a man-made raw material for many industries, which is utilized up to 92% in dry form and is of practical interest in the production of effective thermal insulation building materials and products as a filler and an aggregate. In view of the instability of the chemical and mineralogical composition, the content of raw fuel, as well as the pozzolanic activity, the study of the profitability of the production of pozzolanic cements and concretes based on them was carried out, with an increase in sulfate resistance, corrosion resistance of the aggregate while preventing thermal cracking. The expediency of autoclaved gas-ash-slag concretes production with the use of cement with high content of highly basic minerals ‒ alite and tricalcium aluminate is proved. The technology of obtaining ash-alkaline cellular concrete using ash-removal and alkaline component is given. The economic efficiency of cellular ash-containing concretes is justified by the replacement of sand with ash, a 1.2-1.5-fold reduction in lime consumption compared to lime-sand concrete and a reduction of approximately 2 times the capital costs for extraction and processing of raw materials. Comparative physical and mechanical parameters of autoclave and non-autoclave aerated concrete products are given. The process of manufacturing products by vibro-vacuuming and vibratory compaction of ash concrete is presented. The strength data of vacuum concrete are given, which are 30-40% higher than that of vibro- compacted concrete from a rigid mixture. The investigated value of shrinkage as a result of the water-reducing effect of ash, provides a decrease in the water-cement ratio of concrete. Autoclaved and non-autoclaved aerated concrete can compete with such an effective thermal insulation material as mineral wool. They are more effective materials for low-rise and frame housing construction than traditional brick and concrete.

Abstract. The processes of creation of fire-retardant varnish for wood consisting of a mixture of inorganic and polymeric substances are investigated in the work. It is established that the optimization of the inorganic component leads to a directional ratio of mineral acids and urea capable of effective fire protection of the material. Studies have shown that at the initial temperature of gaseous combustion products T = 68 °C, when exposed to the radiation panel, the untreated sample ignited after 146 s, the flame spread over the entire surface, instead, the sample fire-protected varnish did not ignite, the maximum temperature was 105 °C. In this case, as evidenced by the results of heat resistance, there is a change in the structure of the protective film of the coating. The thickness of the protective layer increases due to the decomposition of the composition, which leads to inhibition of oxidation in the gas and condensed phase, change the direction of decomposition towards the formation of non-combustible gases and combustible coke residue, reduce material combustion and increase flammability index. The coating under the influence of high temperature promotes the formation of a heat-insulating layer of coke, which prevents burning and the passage of high temperature to the material, which is confirmed by the absence of the process of ignition of fire-retardant wood. Features of braking of process of ignition and distribution of a flame of the wood processed by a varnish which consist in several aspects are established. This is the formation of a heat-insulating layer of coke, which prevents burning and the passage of high temperatures to the material, which is confirmed by the absence of the process of ignition of fire-retardant reeds. This indicates the possibility of targeted control of high temperature transfer processes to organic material through the use of special coatings for wood products.

Published: April 2021

This publication is dedicated to the energy of Odessa sanatoriums, both disappeared and those on the verge of extinction. A typological classification of sanatoriums is given. It is proposed to divide the sanatoriums into four groups: by the time of their opening and from the point of view of the time of construction of buildings on their territories. According to the proposed classification, a change in the stylistics of the construction of sanatoriums is considered by examples. On the territory of one sanatorium there could be buildings of the period of historicism, monuments of constructivism,architecture of Soviet classicism of the 50s. last century and Soviet modernism. It was revealed that most of the buildings located on the territory of the sanatoriums are architectural monuments, listed in the register of Odessa architectural monuments. It was also revealed that the monuments are in emergency state or are being destroyed and already destroyed.Conclusions on the development of sanatoriums are presented in the form of a table. As a result of writing the article, it became obvious that the architecture of Odessa sanatoriums was insufficiently studied, which makes it possible to conduct detailed research in a number of directions.

The paper focuses on the development and description of an environmental scenography model. The presented material seeks to characterize the concepts included in the complex of “architectural and design scenography”, to identify and summarize thestructural-component composition of thearchitectural and design scenography. The paper is based on the synthesis of the conceptual framework of stage scenography and environmental approach in the design of the architectural environment. Based on the specific experience of architectural theorists and practitioners who experimented in stage scenography, organization of production processes outside the theaters, the parallels were drawn between the theory and practice of environmental and stage scenography.In view of the foregoing, the nomenclature of environmental scenography has been clarified and expanded. It was found that the architectural and design scenography is implemented in the formation of visual impressions as part of various scenarios of user and environment interaction. At the same time, the environment and its components are “mobile substance”, which is perceived in dynamics, in the course of its interaction with users, in spatial amplifications, metamorphoses, overlapping of “pictures”, etc. With a scenographic approach to the design of the architectural environment, the organization of various connections comes to the fore for a variety of visual contact conditions between the environment and the user.The paper describes the concept of “architectural and design scenography” (ADS), outlines the scope of its application in the architectural design, emphasizes the priority of visual perception, provides examples of the mutual enrichment of the scenographic and architectural practice. The definition of ADS as a type of artistic design of the architectural environment aimed at creation of its graphical-plastic image, and the definition of the visual and aesthetic significance of the environment image are clarified. The main functions of the environmental scenography are listed: character,acting functions and designation of the scene.The structural-component composition of the ADS includes 3 compositional systems, 3 architectonic levels, 4 content-related levels, means of expression, composite components, and stages.

The article considers the problems of the formation of the marine facade of the city of Odessa. Based on this, the world experience in the formation of marine facades of the most vibrant coastal cities was studied. It turned out that one of the features of the perception of the city is its panorama and silhouette, where the panorama is a view of the city, and the silhouette is a vertical outline designation of the city. In coastal cities, the formation of an artistic look takes place from the sea and the city, that is, the silhouette and panorama of the city are not only its individual visual feature, but also its hallmark in the field of tourism development. The most responsible and impressive should be the architectural appearance of the city from the sea. Panoramas with views of the building and water, bridges, natural landscape and coastal architectural ensembles open along the water areas. Thus, the coastal territories of the city of Odessa were analyzed in terms of the silhouette of the city from the sea. As a result, it is clear that the silhouette is monotonous and boring, its only feature is port facilities, and the visual perception of Odessa from the sea is not noticeable and cannot compete with other coastal cities of the world, which helps to pay special attention to its coastal territories. To determine the basic principles of the formation of the marine facade of the city of Odessa, the scientific work of Odessa scientists, as well as options for experimental design, were considered. The considered project proposals were based on the creation of a unique marine silhouette of the city of Odessa, as well as the development of tourist and recreational functions on the lands of the water fund. Despite interesting decisions, this entails enormous economic costs and foreign investment. Therefore, the creation of an architectural and compositional solution to the marine facade of the city is possible due to undeveloped coastal recreational zones and depressed economic territories, which is economically beneficial and relevant. Based on the principles that must be taken into account when designing on the coast, it can be concluded that coastal territories can become the dominant objects at the heart of the silhouette of the city. Economic territories that are located far from the coastal zone can be background highrise objects when forming the panorama of Odessa.

Published: April 2021

In the last decades of the twentieth century - the beginning of the twenty-first in the various countries of the world, the active construction of planetariums has continued. Modern planetariums are becoming multifunctional objects, where not only lectures and training sessions with a picture of the starry sky are held, but various social and scientific events, conferences, exhibitions, circle-studio classes, etc. can be held. Planetariums are often included in scientific, educational, museum -exhibition or entertainment complexes, while providing maximum comfort and a variety of additional services for visitors. The projection technique used in stellar halls has changed significantly - from optical-mechanical devices, the planetarium is moving to the use of optical-electronic devices, which opens up new possibilities for a more detailed and effective demonstration of the phenomena and processes occurring in the Universe. In this regard, the requirements for architectural and planning decisions have been changing; innovations in volumet-ric-compositional and constructive solutions of planetariums appear. Since recommendations on the design of this type of building were issued more than thirty years ago, it is necessary, based on an analysis of modern experience in the design, construction and operation of planetariums, to develop recommendations for improving the architectural and planning decisions of these objects for further use in modern design practice and educational design.

Split air conditioning (AC) is the most widely used in the community for both commercial and domestic utilities. At the present refrigerant which used in Split AC is mostly common group of HFCs, such as R410a. R410a is a zeotropic refrigerant and if there is a leak in the system, it cannot be added this refrigerant. This will increase the cost of maintenance. The aims of this research is to investigate the retrofit of R410a with R32 on the Split AC system. The R32 is chosen because it has higher latent evaporation heat at the same temperature and has less effect on global warming. The refrigeration effect, the power consumption and the system performance are the main three quantities that want to be examined in this research which are observed before and after retrofit. Experimental investigation conducted during this research, including design and manufacture of experimental equipment, calibration and tools installment, collecting the experimental data and analysis by quantitative description method before and after retrofit. The results informed that cooling effect increased during the research, but the COP system has a slight decrease about 4%. R32 refrigerant is quite feasible as a retrofit refrigerant to R410a refrigerant.

Bali kaya akan potensi dan berbagai sumber daya alam yang dapat menunjang kehidupan masyarakat, salah satunya adalah padi yang banyak dimanfaatkan oleh masyarakat dan diolah menjadi beras sebagai bahan pokok nasi. Desa Jatiluwih, Kabupaten Tabanan merupakan salah satu daerah di Bali yang mempunyai potensi sektor pariwisata. Proses perontokan padi masih dilakukan secara manual menggunakan meja kayu atau dengan mesin perontok padi dengan motor bakar diesel. Proses kerja manual banyak membutuhkan tenaga dan waktu yang cukup lama dalam proses merontokkan padi, sehingga produktivitas menjadi rendah. Dipihak lain penggunaan mesin perontok padi bertenaga motor bakar diesel kurang ramah lingkungan. Untuk mengatasi masalah tersebut perlu upaya alternatif untuk memudahkan proses merontokkan padi yaitu dengan menggunakan mesin perontok padi dengan penggerak motor listrik dengan matahari sebagai sumber energi. Setelah dilakukan perhitungan, hasil perencanaan yang diperoleh, motor 200 watt dengan diameter poros 1 inchi dan bantalan yang digunakan adalah bantalan gelinding dengan diameter dalam 25 mm, gir 50 mata untuk di mata perontok dan 25 mata untuk di motor listrik dan rantai yang digunakan adalah tipe 428H dengan panjang 1000 mm.

Education is an important thing in a person's life, because by having adequate education, one's life will be better. Education can be obtained formally through formal institutions that constructively provide a person's abilities academically. This study aims to determine student performance in terms of academic and non-academic domains at a certain time during their education using techniques in data mining (DM) which are directed towards academic data analysis. Academic performance is delivered through the Educational Data Mining (EDM) integrated data mining model, in which the techniques used include classification (ID3, SVM), clustering (k-Means, k-Medoids), association rules (Apriori) and anomaly detection (DBSCAN). The data set used is academic data in the form of study results over a certain period of time. The results of EDM can be used for analysis related to academic performance which can be used for strategic decision making in aca-demic management at higher education institutions. The results of this study indicate that the use of several techniques in data mining together can maximize the ability to analyze academic performance with the same data source and produce different analysis patterns.

Tuberculosis (TB) is a chronic disease that is still a public health problem globally, including Indonesia, due to its easy transmission. Treatment for TB sufferers consist of several drug combinations that are intended to eradicate germs. For TB sufferers, the key to successful treatment is the patient's compliance with taking medication every day. The lengthy treatment time is usually at least six months allowing non-adherence to taking the medication by the patient. If not treated properly, there will be a risk of disease complications, such as tuberculosis bacteria resistant to drugs, making TB treatment more difficult. In this study, an Android-based was built to remind TB sufferers to take their medication during the treatment process. In addition to the mobile-based application, there is also a web application used by drug drinking supervisors (PMO; Petugas Minum Obat in Indonesia) in monitoring TB patients, where the application can also view patient compliance statistics in taking medication and historical data on TB patients’ medical treatment. After completion and development, the application will be given to PMO officers and patients to be tested. It is hoped that the application can help the TB treatment process become more effective and prevent treatment failure from the implementation.

The spreading of COVID-19 has forced many schools in the world to implement e-learning learning. The application of e-learning learning policies reaps the pros and cons of an Indonesian citizen. Junior high school students have their own opinions regarding the implementation of e-learning. Framed within a descriptive quantitative analysis, this study aimed at exploring the perceptions and expectations of junior high school students regarding the implementation of e-learning. A survey was conducted by distributing a questionnaire to Stella Maris junior high school students in East Nusa Tenggara province. One hundred forty-two students from grade seven and eight participated in the study. The survey data were analyzed using Microsoft Excel 2016 and the Statistical Program for Social Sciences (SPSS) v.20. Before data analysis was carried out, the research instruments were examined using the Product Moment Pearson correlation to assess its validity and reliability. The test results indicated that the instrument used was sufficiently valid and reliable, with each indicator having a count-r > r-table (0.514). The results showed that a high percentage of students have willing to learn online. However, the availability of online learning instruments is a barrier to implementing online learning in their school. Students’ perception was analyzed by using descriptive statistics, namely percentage. Students’ responses were analyzed using the content analysis technique.

To identify the genetic diversity of futsal players in Al Hilla Sports Club for the season (2020-2021) after they were exposed to physical exertion by testing lactic mlss in the speed of recovery and elimination of lactic acid. The main experiment included two phases. The first is knowledge of the genetic diversity of the players. The first advanced level of this gene reached (5 players), the middle level (4 players), and the low level of the gene (3 players), and the second stage Of the experiment is to measure the searched variable (lactic acid) for all levels of the gene and to detect players who have a rapid elimination of lactic acid products. The experiment lasted for (2 months) and the most important conclusions were the high level of the MCT1 gene, the speed of elimination of lactic acid in the working muscles. There is a discrepancy between the hospitalization and the exercises. It appeared that the players who belong to this level have slow recovery Very compared to other levels, and this indicates that they are tired quickly. The players of this level have the advantage of quickly getting rid of lactic acid and recovering recovery compared to the low level, and they show less fatigue than the low level. The speed of elimination of lactic acid is less than the speed of its production, which facilitates the transfer of lactate from the working muscle to the blood and speed to get rid of it. Increasingly intense physical exertion affects the variation in the MCT1 gene level. The players at the high level of the MCT 1 gene showed an advantage in the speed of elimination of lactic acid production compared to the low and medium levels.

INFORMAL PEACE-BUILDING ENHANCERS: THE ROLE OF WOMEN IN COLONIAL UZAIRUE LAND, NIGERIA, 1897-1960
Authors:   University of Lagos, Idaewor Osiomheyalo
Published: April 2021

This paper examines the roles played by women in the maintenance and sustenance of a peaceful society through the development of informal socio-economic institutions in colonial Uzairue land. It notes that the roles played by women in this regard have not received adequate scholarly attention. It further explores a socio-political overview of colonial Uzairue land, women in Uzairue worldview, and gender (women) theories, stereotypes and roles in Uzairue land. It uses the qualitative historical method which is narrative, descriptive and analytical. The data used for this research were derived from both primary and secondary sources. The primary data were derived from oral interviews through oral discussions and interactions (by this researcher), with selected interviewees during fieldwork in Uzairue land. The secondary data were obtained from relevant published materials including books and journal articles. This research examines the role of women in Uzairue land in the provision of a peaceful society, and the encouragement of socio-economic progress, through the provision of health care services, occupational and economic ventures. It views the concept of peace-building as efforts, techniques and approaches aimed at preventing conflicts, achieving durable peace, and stabilizing society politically and socio-economically. This study concludes that the instinctive roles of women as caregivers, comforters, peacemakers, and home keepers, and their respective participation and specialization in the provision of health care services, among other socio-economic ventures, undoubtedly encouraged the mutual and peaceful development of colonial Uzairue land. It demonstrates therefore that women are intrinsically linked with the peace-building process and overall development of society, and that they should be accorded high regards even in the contemporary period.

Authors: SARIÇAM Gülhan
Published: April 2021

Aim: Long-term acute care hospitals (LTACH) provide specialized care for patients recovering from severe acute diseases and for patients with chronic and critical illnesses; who need long-term ventilatory support. This study aimed to investigate the factors affecting the length of stay in our long-term intensive care unit (LTICU) in patients with stroke. Material and Method: This retrospective study included 200 stroke patients; who were followed up in the LTICU. The demographic characteristics, comorbid diseases, and culture results of the study patients were examined as variables and the effects of these variables on the length of intensive care unit stay were investigated. Result: Of the patients; the mean age was 79(41-99) years, 99 (49.5%) were males and the mean length of stay was 46 (7-463) days. The length of stay in LTICU was significantly long in stroke patients with a tracheostomy and positive growth in urine cultures (p = 0.013, p = 0.018). The length of stay was significantly short in patients; who received TPN (p = 0.006). Conclusion: Our study has demonstrated that growth in tracheostomy and urine cultures increased but TPN significantly decreased the length of stay of stroke patients in LTICU. To optimize LTACH facilities for stroke patients; we suggest that the overall pattern of the use of such centers should be better known, further integration with acute care units should be established, and further studies should be conducted.

Published: April 2021

Aim: To establish the accuracy oftransvaginal ultrasonography, saline infusion sonohysterography and hysteroscopy in diagnosing uterine pathology in patients with abnormal uterine bleeding.

Material Metod : In our study, Transvaginalultrasonography (TVUSG), Saline infusion sonohystygraphy (SIS) and Hysteroscopy were applied to 60 patients in the reproductive period, who did not use any contraception method other than condom, who did not have chronic and systemic diseases, who applied to our clinic with abnormal uterine bleeding. Dilatation & Curettage (D&C) was applied to all patients after the procedure. Histopathology results obtained with D&C were compared with those obtained with TVUSG, SIS and Hysteroscopy.

Results: Histopathologically,28 patients (46.7%) endometrial polyp, 4 patients (6.7%) submucomyomia, 10 patients (16.7%) endometrial hyperplasia was in the form of endometrial changes due to cycle irregularities in 18 patients (30%). The sensitivity, specifieity, positive and negative predictive values for detection of intracavitary pathology by transvaginal sonography were 71,42%, 77,78%, 88,23%, 83,85%. The value s determined by saline infusion sonohysterography were respeetively 88.89%, 90,48%, 80.00%, 95.0% and the values determined by hysteroseopy were respeetively 100%,90.00%,95,24%, 100%.

Conclusion: TVUSG and SIS is a cheaper, easier and highly diagnostic value procedure for detecting endometrial pathologies such as endometrial polyps and submucous myomas. However, due to the high diagnostic values, low complication rates, direct biopsy and simultaneous treatment, we believe that hysteroscopy will maintain its 'gold standard' feature in the diagnosis and treatment of endometrial pathologies for many years.

COMPARISON OF HYDROXYETHYLSTARCH 130/0.4 AND RINGER’S LACTATE ON FIBRINOGEN LEVEL IN CAESAREAN OPERATIONS: A RANDOMIZED CLINICAL TRIAL

Background and Aim:

Colloids are effective in volume resuscitation but they have been shown to have negative impacts on fibrin formation. The aim of this study is to evaluate the effect of using low dose HES solutions on fibrinogen level in caserean operations.

Materials and methods:

100 women, scheduled for Caserean surgery with spinal anesthesia were enrolled in the study. Patients were assigned to receive hydroxyethyl starch (HES) 130/0.4 in addition to a basic infusion of Ringer’s lactate (RL) solution (GROUP HES) or exclusively RL solution throughout the intraoperative study period (GROUP RL). Patients in the Group HES received HES 130/0.4 8 ml.kg-1h-1 with RL solution 5 mL.kg-1.h-1 and Group RL received RL solution 20 mL kg-1.h-1. Fibrinogen, haemoglobin, platelet values were recorded preoperatively and at postoperative first hour.

Results:

HES 130/0.4 was used only in Group HES, amount consumed was 418 ± 90 mL. Ringer’s lactate consumption was 276 ± 58 mL for Group HES and 1197 ± 197 mL for Group RL. There was a significant change in haemoglobine and fibrinogen values before and after surgery between groups. The mean decrease in fibrinogen was 92.18 ±60.12 mg/dL in Group HES and 65.70 ± 83.61 mg/dL in Group RL.

Conclusion:

HES 130/0.4 solution can be used in elective Caeserean operations without predicted or active hemorrhage. When there is a hemorrhage of any reason in HES 130/0.4 used cases, the decrease in fibrinogen level must be anticipated and rapid replacement of fibrinogen must be kept in mind.

Aim: Thyrotoxicosis is a clinical state of inappropriately high levels of free T4 (thyroxine) and/or free T3 (tri-iodothyronine) in the body caused by distinct etiologies including Graves’ disease (GD), subacute thyroiditis (SAT), toxic adenoma and toxic multinodular goiter (TMNG). Simple hematologic indices such as neutrophil/lymphocyte ratio (NLR), and platelet/lymphocyte ratio (PLR) and mean platelet volume (MPV) have increasingly been mentioned as measures of presence and severity of thyrotoxicosis. In this study, we aimed to analyze whether there is a link between these peripheral blood parameters and the presence of thyrotoxicosis.

Material and Methods: A total of 46 GD, 46 TMNG, 39 TA and 45 SAT patients and 45 control subjects were studied. Laboratory parameters in all patients were recorded and NLR, PLR and MPV values were recorded from peripheral blood complete blood cell counts.

Results: This study showed that NLR and PLR levels are elevated in patients with SAT in comparison with other thyrotoxic patient groups and controls. The post hoc analysis of comparison of NLR and PLR in each study groups revealed that NLR and PLR were statistically different in the SAT group in comparison to the GD, TMNG, TA, and healthy controls. A significant decrease in the level of MPV was demonstrated in thyrotoxicosis patients (p

A gépesített háború elméletének nyugat-európai teoretikusai a két világháború között
Authors: Harka Ödön
Published: April 2021

Eimannsberger tüzérségi tábornok osztotta a szovjet katonai teoretikusok mély hadműveletre vonatkozó elképzeléseit, azonban a hangsúlyt a harckocsik tömeges alkalmazására helyezte. Végkövetkeztetése az volt, hogy a (támadó) harckocsik nem kerülhetnek többé  védtelen arcvonalakkal szembe, a védelem alapját a páncélelhárító fegyverek képezik. Guderian tábornok a harckocsifegyvernem feladataként határozta meg azt, hogy azok az alkalmazásuk szempontjából megfelelő sávban az ellenség előkészített védelmére csapást mérjenek, támaszkodva a meglepetés erejére. Elfogadva a jelen cikk első részében már részletesen körülírt, John Frederick Charles Fuller által kidolgozott megközelítést, de Gaulle alezredes Franciaországot csak abban az esetben látta megvédhetőnek egy meglepetésszerű német támadással szemben, amennyiben rendelkezik egy hivatásos katonákból álló, gépesített hadsereggel.

Akkor és most
Authors: Ambrus István
Published: April 2021

A tanulmány az életvitelszerű közterületi tartózkodás szabályainak megsértése szabálysértését vizsgálja retrospektív és dogmatikai (elemző) módszerrel. A bevezetésben bemutatja az Alaptörvény és a szabálysértési törvény releváns, 2018. október 15. napjától hatályos módosításait, majd áttekinti a kihágás történeti és a szabálysértés jelenlegi fogalmainak jelentését. A jogtörténeti pont célja feltárni az új szabályozás büntetőjogi előképeit, amely alapján kijelenthető, hogy a tényállás nem előzmény nélküli intézmény. Ezt a szabálysértési tényállás dogmatikai elemzése követi, majd a tanulmány értékeli a szabályozás alkotmányosságát vizsgáló alkotmánybírósági határozatot. A munka konklúziója, hogy az életvitelszerű közterületi tartózkodás szabályainak megsértése, jóllehet az Alaptörvénnyel összeegyeztethető, az elkövető által a közterületen megvalósított más tényállások mellett szerepe csak kiegészítő jellegű lehet.
A bírói felelősség kérdésének megítélése a gyakorlatban
Authors: Homoki-Nagy Mária
Published: April 2021

Az 1871:VIII. tc. rendelkezett a bírák fegyelmi felelősségéről. A fegyelmi vétség két nagy csoportját határozta meg, az egyiket az úgynevezett hivatali bűntettek képezték, amelyeknek a körét a törvény taxatíve felsorolta. Ebben az esetben rendes büntetőeljárást kellett indítani. A fegyelmi vétségek másik körét a hivatali kötelességszegések alkották. A tényleges szabályszegés mellett ide tartoztak mindazon cselekmények, amelyekkel a bíróság tekintélyét, a bíróságba vetett bizalmat csorbította valaki. A Szegedi Ítélőtábla fennmaradt iratai között a szerző arra kereste a választ, mely cselekményeket minősítettek olyannak, amelyek esetében fegyelmi vétséget a fegyelmi bíróság megállapított. A feltárt levéltári források alapján a bírák által betartandó ügyrendi szabályok megsértése, jegyzőkönyvek aláírásának elmaradása volt a leggyakoribb. A bíróság tekintélyének a csorbítását azok a cselekmények képezték, amelyek esetében a kor erkölcsi szabályainak a megsértését állapították meg. A források alapján megállapítható, hogy írásbeli figyelmeztetés vagy feddés a legtöbb esetben elegendő volt, néhány súlyosabb esetben pénzbüntetést szabtak ki, esetleg az áthelyezés kivételes eszközét alkalmazták.
Közigazgatási büntetőjog és alapjogi garanciák
Authors: Hollán Miklós
Published: April 2021

A tanulmány azt vizsgálja, hogy a nullum crimen et nulla poena sine lege alapelv miképpen érvényesül a közigazgatási szankciók tekintetében. A szerző áttekinti az Európai Emberi Jogi Bíróság, az Európai Unió Bírósága, illetve az Alkotmánybíróság válogatott döntéseit. Különös figyelmet fordít a 30/2014. (IX. 30.) AB határozatra, amely lényeges fordulatot hozott az ítélkezési gyakorlatban. A testület ugyanis ebben a döntésében kifejezetten kiterjesztette az Alaptörvény XXVIII. cikk (4) bekezdésében biztosított garancia hatályát a közigazgatási szankciókra, miközben azonban annak védelmi szintjét ezekre nézve lecsökkentette a klasszikus büntetőjoghoz képest.
