Case History: Analysis of Interlayer Shorts in a 0.5 µm CMOS IC Technology
Authors: Soden J.M. , Henderson C.L. , Cole E.I.
Published: June 2022

Sandia National Laboratories manufactures 0.5 µm CMOS ICs using local oxidation of silicon (LOCOS) and shallow trench isolation (STI) technologies. A program based on burn-in and life tests is being used to qualify the process for military and space applications. Representative ICs from baseline wafer lots are assembled in ceramic packages and electrically tested before, during, and after burn-in and subsequent life tests. Two types of ICs are being used for this qualification, a 256K-bit SRAM and a microcontroller core. More than 600 ICs have passed qualification tests with very few failures, although recently, a group of SRAMs from a development wafer lot incorporating nonqualified processes had an usually high number of failures during their initial electrical test after packaging. This article describes the investigation that was conducted to determine the cause of these failures.

Applications of SCM and SCS to Failure Analysis
Authors: Edwards Hal
Published: June 2022

Scanning capacitance spectroscopy (SCS) is a new way to use a scanning capacitance microscope (SCM) to delineate pn junctions in silicon devices. SCS produces two-dimensional pn junction maps with features as small as 10 nm. It can also estimate the pn junction depletion width and hence doping levels near the junction. This article explains how SCS and SCMs allow a whole new regime of doping-related phenomena to be explored in Si devices and ICs.

Nutritional problems can occur in various groups, especially at a very vulnerable age, namely the infancy and toddler period because of the high nutritional needs to support growth and development at this time. The current condition of the Covid-19 pandemic can affect these nutritional problems due to the increasingly difficult economic conditions of the community, such as a decrease in family income which has an impact on the ability to meet daily family needs, so that it has the potential to cause various problems, especially nutrition and health problems. In addition, the mother's knowledge of proper nutrition presentation patterns can also affect the condition of the family's nutritional status, especially during this pandemic. The consequences of nutritional problems in this pandemic era will cause short-term and long-term problems in the health, social and economic sectors. This study aims to determine the description of family income and mother's knowledge about food serving patterns during the Covid 19 pandemic. This type of research uses a description with a frequency distribution table, the population is 367 families with toddlers using accidental sampling technique. The results of this study indicate that most of the family's income is still below the minimum wage and knowledge of mothers about food serving patterns is still lacking. Suggestions to the relevant agencies need to increase community empowerment for small businesses to increase family income and increase counseling efforts on the presentation of family nutrition and provide training on processing nutritious food without requiring a lot of money.Keywords: Family income, Mother's knowledge about nutrition, Covid 19 Pandemic

Economic and Political Analysis of Initial Teacher Education from Consensus and Conflict Perspectives in Documents of International Institutions
Authors: Açar Abdullah , Yücel Toy Banu
Published: June 2022

This study aims to reveal the economic and political issues underlying the remarks related to initial teacher education (ITE) in the documents published by international institutions, European Union (EU), Organization for Economic Co-operation and Development (OECD), and United Nations (UN), and to examine these issues from the perspective of consensus and conflict approaches to education. The study is designed as a systematic review. ITE-related 67 documents published by UN, EU, and OECD were analyzed following several coding steps. According to the results, international institutions promote entrepreneurship, life-long learning, and information and communication technologies as economic issues in ITE. As political issues, they put forward social themes including preparing for diversity, quality in ITE including accountability and standards, and structure of ITE including flexibility and autonomy. Although the documents are mainly parallel with the consensus approach, economic and political issues revealed in the study were discussed from perspectives of both approaches. One perspective considers promoting the economic issues in ITE the economic efficiency and growth which is beneficial for all. The other reminds that division of this benefit may include class-based inequalities. Also, different perspectives emphasize different social themes and they bring different explanations for how the quality assurance functions.
Association of circumferential aneurysm wall enhancement with recurrence after coiling of unruptured intracranial aneurysms: a preliminary vessel wall imaging study
Authors: Hara Takeshi , Matsushige Toshinori , Yoshiyama Michitsura , Hashimoto Yukishige , Kobayashi Shohei , Sakamoto Shigeyuki
Published: June 2022

OBJECTIVE

Recent histopathological studies of unruptured intracranial aneurysms (UIAs) have confirmed that aneurysm wall enhancement (AWE) on MR vessel wall imaging (VWI) is related to wall degeneration with in vivo inflammatory cell infiltration. Therefore, pretreatment aneurysm wall status on VWI may be associated with recurrence after endovascular treatment.

METHODS

VWI with gadolinium was performed on 67 consecutive saccular UIAs before endovascular treatment between April 2017 and June 2021. The mean (range) follow-up period after treatment was 24.4 (6–54) months. AWE patterns were classified as circumferential AWE (CAWE), focal AWE (FAWE), and negative AWE (NAWE). The authors retrospectively investigated the relationship between aneurysm recurrence and AWE patterns, as well as conventional risk factors.

RESULTS

Sixty-seven patients with 67 saccular UIAs were eligible for the present study. AWE patterns were as follows: 10 CAWE (14.9%), 20 FAWE (29.9%), and 37 NAWE (55.2%). Follow-up MRA detected aneurysm recurrence in 18 of 69 cases (26.1%). Univariate analysis identified maximum diameter (mean ± SD 5.8 ± 2.2 mm in patients with stable aneurysms vs 7.7 ± 3.8 mm in those with unstable aneurysms, p = 0.02), aspect ratio (1.4 ± 0.5 vs 1.1 ± 0.4, p < 0.01), aneurysm location in posterior circulation (4.1% vs 27.8%, p < 0.01), volume embolization ratio (29.6% ± 7.8% vs 25.2% ± 6.1%, p = 0.02), and AWE pattern (p = 0.04) as significant predictive factors of recurrence. Among the 3 AWE patterns, CAWE was significantly more frequent in the unstable group, but no significant differences in stability of the treated aneurysms were observed with the FAWE and NAWE patterns. In multivariate logistic regression analysis, CAWE pattern (OR 14.2, 95% CI 1.8–110.8, p = 0.01) and volume embolization ratio ≥ 25% (OR 8.6, 95% CI 2.1–34.3, p < 0.01) remained as significant factors associated with aneurysm stability after coiling.

CONCLUSIONS

VWI before coiling provides novel insights into the stability of treated aneurysms. Aneurysms with the CAWE pattern on VWI before coiling may be less stable after treatment.

Russia and the International Institute of Agriculture in Rome: Diplomacy, Ideology, Pragmatics (1905–1945)
Authors: Narukova Nina
Published: June 2022

The first specialised international agricultural organisations emerged in the first half of the twentieth century. The article complements the poorly studied history of the experience of international cooperation within these structures, given that in 1905 Russia was one of the founders of the first international intergovernmental agrarian organisation – the International Institute of Agriculture (IIA). Drawing on official documents from the IIA and the Russian Empire, as well as archival materials from the Soviet period, the author identifies two periods in the history of cooperation between Russia and the IIA: 1905–1917 and 1931–1936/37. The Russian Empire contributed large sums to the IIA budget. The IIA was in contact with Russian imperial authorities and collaborated with the Empire's eminent scientists. The partial restoration of relations between the USSR and IIA in the 1930s was in keeping with the foreign economic interests of the Soviet authorities in the context of the first five-year plans and the implementation of the general political course towards cooperation with foreign scientific, technical, and commercial establishments. The rapprochement between the USSR and IIA began at the International Wheat Conference in Rome in the spring of 1931. The participation of Russia in IIA shows the pragmatic aspects of its foreign policy, as well as the political and diplomatic potential for international communication within the framework of an international specialised organisation.
Review of Current Developments on High Strength Pipeline Steels for HIC Inducing Service
Authors: Entezari Ehsan , González-Velázquez Jorge Luis , Rivas López Diego , Zúñiga Manuel Alejandro Beltrán , Szpunar Jerzy A.
Published: June 2022

Nowadays, an increasing number of oil and gas transmission pipes are constructed with high-strength low alloy steels (HSLA); however, many of these pipelines suffer from different types of hydrogen damages, such as hydrogen-induced cracking (HIC). So many research efforts are being carried out to reduce the detrimental effects of hydrogen damage in HSLA steel pipes. The thermomechanical control process (TMCP) is a microstructural control technique that is able to eliminate the conventional heat treatment after hot rolling. Recent research demonstrated that TMCP provides high HIC resistance without adding high amounts of alloying elements or expensive heat treatments. However, once these HSLA steel pipes are put into service, they experience HIC damage, and the prediction of its kinetics is a necessary condition to perform Fitness-For-Service assessments. To develop a reliable predictive model for the kinetics of HIC, the relations among the microstructural features, environmental parameters, and mechanical properties have to be fully understood. This paper presents a review of the key metallurgical and processing factors to develop HSLA steel pipes, as well as a review of the phenomenological and empirical models of HIC kinetics in order to identify specific research directions for further investigations aimed to establish a reliable and sound model of HIC kinetics.

Published: June 2022

According to the research conducted, the asymmetric multi-storey buildings are complex and suffer from severe damage caused by increased torsional response. This paper addresses the behavior assessment of setback building with irregularity in the plan under severe seismic event such as Kobe earthquake. Using three-dimensional model, the structure is subjected to seismic waves in the three directions through ground accelerations. Nonlinear dynamic procedures have been used by means time-history analysis method. The mechanical model describes physical nonlinear behavior with damage and plasticity showing the regions of cracking propagation, mainly the columns-beams connections and the whole column as well, corroborating the weak column and strong beam concept. The slabs did not present significant failures despite indicating damage regions on the borders of the first floors.

Published: June 2022

Al composites usage is growing and is gaining importance in aerospace, automotive and marine industries due to their excellent characteristics. Aluminum composites exhibit high resistance to wear and corrosion, possess high strength, offer durability and more such properties. In this study, Al 6061 alloy, reinforced with Al2O3 - MoS2 was produced by a stir casting technique and its microstructure and mechanical behavior were evaluated. Reinforcements were added in the range of 0 - 9 wt. %. The microstructure analysis, tensile and compressive strength of the hybrid MMCs (Metal Matrix Composites) have been analyzed and examined. From the investigational study, it was found that the reinforcing particulates are evenly dispersed in the base matrix. The porosity and density of the hybrid composites were found to be enhanced. The ultimate tensile and compressive strength of the hybrid MMCs could be improved by addition of ceramic (Al2O3) particulates compared to monolithic. Further, the strength of hybrid composites was decreased by adding of MoS2 (solid lubricant) along with hard ceramic particulates. Finally, fractured surface of the UTS test specimens were analysed using a SEM analysis.

Published: June 2022

An experimental study with many variables was carried out to investigate the effective width of simply supported composite beams (T&L sec. beams) with & without slab opening. Three full-scale composite slab models with six different carrier simply supported composite beams (three with T-sec. & three with L-sec.) with constant slab rectangularity was tested.  Each model loaded by uniform load (in the elastic zone) then loaded by means of two-concentrated load system acting at equal distances from supports till failure. One of them without slab opening and the others with two symmetric slab openings and constant opening horizontal position. All standard tests were performed and all instructions and precautions were followed as perfect as the laboratory instruments permitted.  All experimental steps were executed in a manner such that meeting practical conditions as exactly as could. In this research, the tested model features, materials properties and measurement instrumentations are described in brief. The maximum load carrying capacity; crack patterns, generated strains and deflections at different positions were experimentally investigated. For the sake of analysis generalization and error minimization, all results were analyzed by means of dimensionless relations. The results were recorded and analyzed guided by their mechanical behavior. Interesting gained results, conclusions and recommendations are introduced.
A Simple and Efficient eight node Finite Element for Multilayer Sandwich Composite Plates Bending Behavior Analysis
Authors: Belkaid Khmissi , Boutasseta Nadir , Aouaichia Hamza , Gaagaia Djamel Eddine , Deliou Adel , Boubir Badreddine
Published: June 2022

In this paper, a C0 simple and efficient isoparametric eight-node displacement-model based on higher order shear deformation theory is proposed for the bending behavior study of multilayer composites sandwich plates. Difficult C1-continuity requirement is overcome by extracting the seven degrees of freedom from strain relations for each element node: two displacements for in-plane behavior and five bending unknowns namely: a transverse displacement, two rotations and two shear angles, which results in a kinematic approximation formulation having only first order derivative requirement. The governing equations of the element (constitutive, virtual work and equilibrium equations) are implemented for the prediction of approximate solutions of deflections and stresses of sandwich plates linear elastic problems. Thereby, the formulation element is able to present a cubic in-plane displacement along both core and faces sandwich thickness, as well as, the shear stresses are found to vary as quadratic field without requiring shear correction factors and independent from any transverse shear locking problems. The accuracy and validity of the proposed formulation is verified through the numerical evaluation of displacements and stresses and their comparison with the available analytical 3D elasticity solutions and other published finite element results.

Public Corporate Governance Kodizes für nachhaltige Daseinsvorsorge und Vertrauen in den Staat: Qualitätsmodell und Diffusion von Governance-Standards
Authors: Papenfuß Ulf , Wagner-Krechlok Kristin
Published: June 2022

Selbstregulierung ist ein Policy-Instrument und Governance-Mechanismus von zentraler Bedeutung zur Erreichung von Politik- und Organisationszielen. Die Relevanz wird im Kontext öffentlicher Unternehmen für nachhaltige Daseinsvorsorge und Vertrauen in den Staat einschlägig betont. Obwohl über 50 deutsche Gebietskörperschaften Selbstregulierung mit Public Corporate Governance Kodizes (PCGKs) etabliert haben, ist die Diffusion von Governance-Standards in diesem Kontext kaum erforscht. Für die wissenschaftliche Debatte um Konvergenz und Divergenz entwickelt dieser Artikel ein Qualitätsmodell zur differenzierten Analyse von Diffusionsmustern in PCGKs und analysiert die PCGKs von Bund, Landeshauptstädten und Stadtstaaten. Die Studie erweitert das theoretische Verständnis zur Diffusion von Governance-Standards im öffentlichen Sektor und zeigt, dass die Diffusion im Vergleich von PCGKs sowie einzelnen Regelungsfeldern (z. B. Geschäftsführungsorgan, Aufsichtsorgan) sehr unterschiedlich ausgeprägt ist und einschlägige Anforderungen bislang nur teilweise erfüllt werden. Abschließend werden Perspektiven zur Erforschung von Determinanten der Qualität von PCGKs und potenziellen Effekten von Qualitätsunterschieden abgeleitet.
A systemic perspective on crisis management and resilience in Germany
Authors: Behnke Nathalie , Eckhard Steffen
Published: June 2022

In the past decades, Germany was hit – in equal measure to other countries in Europe and beyond – by multiple transboundary and societal crises. We take stock of the ability of the German state to cope with the ensuing complexity in managing these exceptional situations. Conceptually, we apply a systemic perspective that asks about the resilience of the German state in the subsystems of policymaking in crises, implementation of administrative crisis management, as well as societal responses to crises. The paper draws on findings from a range of empirical studies assembled in this special issue, that focus either on the so-called refugee crisis of 2015/16 or the Covid-19 pandemic since 2020. Strikingly, the overall impression emerging from this research is generally favorable of the ability of the German politico-administrative system to master challenging crises – its resilience. But there are also areas for improvement.

Authors: Jann Werner
Published: June 2022

The Oxford Handbook of the Quality of Government delivers an authoritative and comprehensive overview of the foundations and findings from the Quality of Government (QoG) research agenda, mainly developed at the QoG Institute founded in 2004 in Gothenburg, Sweden. Starting from a rather narrow concept of QoG, focusing on impartiality, the handbook argues forcefully that the quality of public institutions is crucial for all kinds of social, economic, and political outcomes, that higher levels of QoG are related to higher levels of human well-being and political legitimacy, and are therefore more important than, for example, levels of liberal democracy. This rather narrow perspective of the handbook turns out to be one of its strengths, since all contributions start from identical concepts, while discussing all kinds of theoretical, empirical, and critical objections. All contributions offer very helpful overviews and systematic summaries of existing literature and are therefore very well suited for reading lists in academic courses, both in political science, public administration, and public management, but also in other areas like development studies, and especially also for scholars who may be skeptical of this approach.
Die EZB und die Inflation – ein umstrittenes Verhältnis
Authors: Immerfall Stefan
Published: June 2022

Im Artikel wird zunächst das Mandat der Europäischen Zentralbank (EZB) angesprochen. Sodann wird das Dilemma erläutert, in dem sich die EZB angesichts steigender Inflationsraten einerseits und der Notwendigkeit andrerseits befindet, die Euro-Zone zusammenzuhalten. Im Vergleich zu anderen großen Zentralbanken ist eine beschleunigte Straffung der Geldpolitik von der EZB nicht zu erwarten. Dies gilt unabhängig vom Ukrainekrieg. Abschließend werden mögliche Neben- und Verteilungswirkungen des "billigen Geldes" angesprochen.
Die Wiedereinführung der Wehrpflicht. Alter Wein in neuen Schläuchen?
Authors: Damert Marina
Published: June 2022

Immer mal wieder ist die allgemeine Wehrpflicht Gegenstand in der Politik. Die aktuelle Situation in der Ukraine verstärkt nun die Diskussionen der Politiker zu dieser Thematik. Die Wehrpflicht besteht seit 1956 und ist im Wehrpflichtgesetz geregelt. Demnach sind alle deutschen Männer ab dem 18. Lebensjahr wehrpflichtig. 2011 wurde dieses Gesetz zwar ausgesetzt, allerdings nicht abgeschafft. Geändert wurde es dahingehend, dass die Pflicht zum Dienen erst im Falle eines drohenden Waffenangriffs auf Deutschland gilt. Während die Politiker der verschiedenen Fraktionen sonst so unterschiedliche Meinung haben, verbindet einige angesichts dieser Thematik doch ein Ziel: Die Wiedereinführung der Wehrpflicht. Die Dokumentation zeigt die unterschiedlichen Positionen.

Background. The Stolbovoe deposit is located in the northern part of the Eastern Sayan, in the Nizhneudinsky district of the Irkutsk region, within the N-47-IX map sheet. The surveying of the territory began in the sixties of the last century. The Stolbovoe deposit was discovered based on direct search signs (radioactivity). At the same time, the search was not aimed at revealing new deposits hidden under the Riphean cover; therefore, most of the territory remained unexplored.

Aim. To map and classify the near-ore hydrothermal-metasomatic alterations manifested on the flanks of the Stolbovoe uranium deposit.

Materials and methods. During the 2018–2020 period, within the framework of prospecting work, the employees of the All-Russian Scientific-Research Institute of Mineral Resources named after N.M. Fedorovsky (VIMS) carried out the mapping of ore alterations using an innovative method of Infrared (IR) spectroscopy. The diagnostics of mineralization was carried out using a portable TerraSpec 4 Hi-Res spectrometer. The instrument was used to measure diffuse reflectance spectra in the Ultraviolet-Visible-Short-Wave Infrared (UV-Vis-SWIR) ranges; the composition of various mineral phases was determined using the TSGVersion 7 database and software.

Results. This study confirmed the efficiency of the method applied for the diagnostics of all varieties of clayey (kaolinite, montmorillonite) and fine micaceous (phengite, sericite, paragonite and their illite varieties) minerals, as well as carbonates (dolomite, ankerite, siderite) and chlorites in the rock in situ or in samples without preliminary sample preparation.

Conclusions. The use of the described method for investigating cores and samples of the Stolbovoe uranium deposit (East Sayan region) made it possible to classify the epigenetic changes in rocks and to map hydrothermal-metasomatic halos, including those near-ore, formed by mineralization that could not be identified by conventional visual and optical methods.
Petroelastic modeling of carbonate reservoirs in the view of different void types
Authors: Grigoryan Ya. S. , Bayuk I. O.
Published: June 2022

Background. Fractures present in carbonate rocks facilitate fluid flow within void spaces. Each type of voids can have a different effect on rock elastic properties, which, in turn, allow the characteristics of voids to be estimated by assessing the velocity of elastic waves. In this paper, an effect of pores and fractures on the velocity of elastic waves is analyzed by petroelastic modeling. An example of solving an inverse problem is presented, involving the determination of fracture porosity and relative fracture opening using the data on elastic wave velocity and hydrocarbon reservoir density obtained during geophysical well logging.

Aim. To increase the accuracy of experimental data on the velocity of elastic waves that propagate across hydrocarbon carbonate reservoirs by assessing the pore and fracture characteristics of voids.

Materials and methods. The effective medium theory was used as an efficient way to evaluate physical, including elastic, properties based on rock composition and microstructure. Using Berryman’s self-consistent method, we created a model of rock elastic properties, or a petroelastic model, the void space in which was represented by isometric pores and fractures. This model was applied to a well in a petroleum province in West Siberia.

Results. The effect of characteristics determining the void space of porous-fractured rocks on the velocity of elastic waves was defined. Velocity surfaces were constructed in accordance with changing parameters of the model, i.e. fracture porosity and fracture aspect ratio. The obtained theoretical and experimental data were compared in order to determine fracture development zones and to evaluate volume concentration and relative fracture opening in these zones.

Conclusion. The effect of pores and fractures on elastic wave velocity in porous-fractured carbonate reservoirs was studied by petroelastic modeling. The zones of excessive fracturing were defined and the parameters of volume concentration and relative fracture opening were determined using the data obtained by geophysical well logging in a petroleum province in West Siberia.

ANALISA DEBIT BANGKITAN MENGGUNAKAN MODEL ARIMA (AUTOREGRESIF INTEGRATED MOVING AVERAGE)
Authors: Utari Ririn , Martini Sri
Published: June 2022

Flow discharge data must be available in a time series and accurate manner, so there should be no empty periods. Therefore, a model is needed that can reconstruct or estimate the flow discharge of the empty period stochastically. One way to solve this problem is by filling in data or data generation.The philosophy of data is to create new data sets based on generally incomplete or short historical data to obtain longer and more complete data. The new complete and long data is made with properties as well as short data as the source (Sri Harto and Sudjarwadi, 1989). Model ARIMA represents three modeling namely of autoregressive model (AR), moving average (MA), and autoregressive and moving average model (ARMA) which has characteristic of two models. First stage modeling ARIMA is testing stationary data, identification model, estimation parameter model and forecasting. Data used in this model Arima is discharge complete station Maribaya DAS Cikapundung Hulu if from years 1978 from the research. Results ARIMA model produces correlation values of 0.657 with a target value of 1. For the absolute relative error rate (KAR) and the average error rate (RMS) each produces a value of 0.0052 and 0.017 with a target value of 0. The ARIMA model can be used to fill in, generate discharge data and can be used to predict future flow rates. In discharge forecasting, the ARIMA model is only able to predict discharge accurately in a short time span. For long-term forecasting, the resulting forecast will tend to be flat (flat/constant).

Qualitatively, according to the waste in the construction sector in Indonesia, it is quite large, namely 57% when compared to the manufacturing industry which has 26% waste, the inefficiency in megaprojects is caused, among others, by too many design changes, low work expertise, delays in decision making, coordination that is not good between the parties involved, weak planning and control, delays in material delivery, and inappropriate work methods. Lean construction concept is used to eliminate waste and maximize value for users or customers. In addition, he said that the framework is a step-by-step guide in the form of a suitable guide to facilitate the implementation of the lean construction concept because the lean construction concept is a process-based concept. The purpose of this study is to identify critical factors that support and hinder the implementation of the lean construction concept in mega projects in Indonesia. In this study, a systematic literature review was used to examine the supporting factors and inhibiting factors for the implementation of lean construction. After conducting a literature review, four main supporting factors were obtained, namely managerial, labor, organizational and external. The managerial sub-factors are management commitment and Leadership Management. In addition, it was also found that the barrier factors from the implementation of lean construction were managerial, workforce, company/project organization and external. The supporting sub-factors of managerial are management commitment, management leadership, Management is unable to change existing construction concepts, Lack of training for contractors and subcontractors, misconceptions about lean construction method
Kórházak biztonsága és védelme 2. – személy- és vagyonvédelmi eszközök lehetőségei
Authors: Veresné Rauscher Judit , Berek Lajos
Published: June 2022

Az egészségügyi létesítmények, azon belül is a kórházak a kritikus infrastruktúra részét képezik mind műszaki, mind  társadalmi szempontból. A legfontosabb feladatuk a gyógyítás, amit különböző vészhelyzetekben is folytonosan  biztosítani szükséges. Emiatt fontos kérdés, hogy a kórházakban milyen külső és belső veszélyforrások merülnek fel kockázatként és azok milyen védelmi megoldásokkal csökkenthetők. A két részből álló cikksorozat 2. részében a korábban feltárt kockázati tényezők típusai, jellemzői alapján nemzetközi ajánlások és saját tapasztalatok alapján meghatározzuk, hogy azok elkerülhetők-e, és ha igen, akkor milyen megelőző biztonsági kialakítással vagy tevékenységgel csökkenthetők a kockázataik és a hatásuk. A kutatásunk alapján kijelenthető, hogy a kórházakat fenyegető veszélyek teljes mértékben nem kerülhetők el, azonban biztonsági  intézkedésekkel csökkenthetők a kockázatok. A cikksorozatban feltártuk a kórházakat érintő speciális kockázati tényezőket, és javaslatot adtunk azok  lehetséges csökkentésére vagy elkerülésére. Fontos tényező azonban,  hogy minden egyes intézmény  egyedi funkcióval és  kialakítással rendelkezik, így az  általános útmutatás mellett mindig szükséges az  egyedi elemzések elkészítése és a  szükséges  megelőző tevékenységek meghatározása.  Ezekkel  jelentősen növelhető az egészségügyi  intézmények,  különösen a kórházak működődési  biztonsága, ami  egyben kihatással van azok gazdasági és  társadalmi  megítélésére is.
Are Traditional IT System Interoperability Solutions Sufficient and Efficient? Thoughts on Novel Solutions
Authors: Munk Sándor
Published: June 2022

In our globalised world the interoperability of organisational IT systems has become an indispensable  condition for the cooperation of organisations, so IT  interoperability is now a priority demand of all application.  In practice, we can essentially only find solutions based on  standardised intermediary representations, but these have a number of limitations, the analysis of which is not covered in the literature. Novel interoperability solutions have also  emerged in connection with the development of  information technology, but little is said about the general  requirements for innovative solutions. This publication  seeks to contribute to these tasks.
