No Special Status: Ecologies Of Agency In Ecology
Authors: Woodard Ben
Published: February 2023

This paper is based on the lecture held on 11th May 2022 in the context of Maska seminar at Nova Pošta and it examines general conceptual distinctions at work in the history of the life sciences (namely agency, form, force, and form) and how these have been emphasized or neglected in the various ontological and ecological turns within the humanities (from the critical humanism of Marxism to post-humanism and the nonhuman). More specifically I look at the work of Sylvia Wynter and how her project of decolonising the notion of ‘Man’ makes the possibility of a counter humanist uptake of a politically critical philosophy of biology.
Waves as a hydro-choreographic material in the hydrocene
Authors: Bailey-Charteris Bronwyn
Published: February 2023

The Hydrocene is the watery epoch that I propose to name the tide of art going into the blue in response to the climate crisis. In this essay I analyse and argue for the potential significance of waves as hydrochoreographic materials in eco-critical performance practices. I look to the work of Swedish based artist-choreographer Pontus Pettersson in his expansive and watery body of work All Departures are Waves (2018-) and British based artist, dancer and choreographer Temitope Ajose-Cutting in her video work How to Move Like the Ocean (Liquefaction, Lubrication & Expansion in Twelve Easy Steps) (2019). I relate Pettersson’s queering of water practices to theorist Stefan Helmreich work in The Gender of Waves. Further I look to the wave as a hydro-choreographic offering in the Hydrocene and point to the potentiality of the wave as a queer and disruptive force in contemporary eco-critical performance practices.

Reviews given by application users have an essential role in the decisions of potential users before deciding to use a service. Users can provide reviews of application services on the Google Play Store. A large number of reviews makes the data collection and analysis difficult if done manually. Therefore, a particular method is needed to collect and analyze these reviews automatically to obtain the hidden essential information. Topic modeling is an extension of text analysis that can find main themes or trends hidden in large sets of unstructured documents. This study applies topic modeling with the Latent Dirichlet Allocation (LDA) method for Netflix application review data sourced from the Google Play Store web. The Latent Dirichlet Allocation (LDA) method is a probability model from textual data that can explain the hidden semantic themes in the review document. This research aims to analyze hidden topics that application users discuss. The results of topic modeling show that of the twelve topics generated, the most discussed topic by users is payment methods.

The brutal reality of barbarian aggressive war in the middle of Europe demands the full mobilization and unification of powers not only of Ukraine, but also of such important actors as European Union member states. However, unfortunately it turned out that European Union again faces internal arguments and lack of unity, despite such unambiguous situation. The articles analyses the number of EU member states according to their position in the Russian-Ukrainian war and discusses what might be the reasons and consequences.
Jean Grondin i aktualność jego perspektywy hermeneutycznej dla Europy i świata
Authors: Szymczyński Tomasz R.
Published: February 2023

Europa i świat szczególnie ostatnimi czasy napotykają ponownie na coraz to nowe wydarzenia i procesy, których ujmowanie w kategoriach innych niż cierpienie byłoby trudne do uzasadnienia. Taki stan rzeczy prowokuje do formułowania pytań o sens egzystencji wpisanej w tego rodzaju okoliczności. W tym kontekście Jean Grondin, wychodząc od założeń hermeneutyki filozoficznej Hansa-Georga Gadamera, przekonuje, by zamiast przyzwalać na założenie o relatywizmie, co niesie szereg daleko idących konsekwencji dla naszego rozumienia otaczającego nas świata, powracać do tkwiącego u podstaw kultury zachodniej stanowiska, że sensownie można rozważać egzystencję człowieka wyłącznie w wyraźnie zarysowanych dla niej granicach, gdyż tylko wówczas mamy szanse na odnalezienie stosownej miary w odniesieniu do tego, jak określić nasze miejsce i jego sens. Brak zgody na ów relatywizm Grondin uzasadnia poprzez zwrócenie uwagi na fundamentalne rozróżnienie między fragmentami i całością rzeczywistości, którego zlekceważenie uznaje za jedną z ważnych przyczyn popularności tego współczesnego nurtu.

Na tej podstawie ukazuje się, że właśnie w wyniku braku adekwatnego rozpoznania tego wyzwania w obszarze nauki i edukacji nasz świat społeczny zdaje się podlegać postępującej radykalizacji o dychotomicznym kształcie. Z jednej strony, staje się coraz bardziej zmatematyzowany, a z drugiej, trudna sztuka mądrości praktycznej ulega degradacji w wyniku daleko idącej polityzacji, w ramach której coraz większy rozdźwięk uwidacznia się między tym, co deklarowane oraz tym, co faktyczne. Natomiast zadanie problematyzowania tego stanu rzeczy, które powinno być traktowane jako jeden z zasadniczych celów nauk humanistycznych i społecznych zastąpione bywa jedynie skrupulatnym odnotowywaniem tego, co w efekcie braku tego rodzaju refleksji się wokół nas oraz z nami dzieje.
Geneza Trójkąta Weimarskiego i jego rola w integracji Europy po zakończeniu zimnej wojny
Authors: Fiszer Józef M.
Published: February 2023

Artykuł przedstawia genezę Trójkąta Weimarskiego i jego rolę w integracji Europy po zakończeniu zimnej wojny. Na temat Trójkąta Weimarskiego, choć minęło już trzydzieści lat od jego utworzenia w literaturze przedmiotu w Polsce, Niemczech i Francji nadal krążą sprzeczne oceny i opinie. Z jednej strony podkreśla się jego duże znaczenie w procesie akcesji Polski do struktur euroatlantyckich, tj. do NATO i Unii Europejskiej (UE), a z drugiej strony deprecjonuje się jego rolę w reorientacji polityki zagranicznej Polski po 1989 roku podkreślając, że racja stanu Polski została podporządkowana interesom Niemiec i Francji.

Zarówno w Polsce, jak i w Niemczech czy Francji Trójkąt Weimarski często był i jest nadal traktowany instrumentalnie, zwłaszcza przez polityków, którzy wykorzystują go do bieżącej polityki międzynarodowej i w relacjach dwustronnych. Tymczasem nie ulega wątpliwości, że odegrał on dużą rolę nie tylko w procesie utworzenia UE, ale również determinował jej poszerzanie i pogłębianie, choć jego potencjał i możliwości nie były w pełni wykorzystane. Można stwierdzić, że odegrał on dużą rolę w integrowaniu Europy po zakończeniu zimnej wojny.

Analiza działalności Trójkąta Weimarskiego oraz jego sukcesów i porażek pokazuje, że jest on wciąż niezbędnym podmiotem w stosunkach międzynarodowych i powinien odgrywać istotną rolę w procesach integracji Europy. Nadal też powinien odgrywać zasadniczą rolę w umacnianiu trójstronnej polsko-niemiecko-francuskiej współpracy i umacnianiu pozycji Unii Europejskiej w stosunkach międzynarodowych, której aktywność w ostatnich latach mocno zmalała. Renesans Trójkąta Weimarskiego jest nie tylko możliwy, ale wręcz niezbędny w obecnej sytuacji międzynarodowej w Europie i na świecie, którą determinuje agresja Rosji na Ukrainę oraz groźba wybuchu trzeciej wojny światowej.
„America First”. Relacje administracji Trumpa z Unią Europejską
Authors: Kiwerska Jadwiga
Published: February 2023

W artykule przedstawiono działania administracji Trumpa wobec Unii Europejskiej. Analizując problem, starano się dociec przyczyn napięć na linii Waszyngton–Bruksela oraz zarysować główną oś sporu. Były nią napięte relacje handlowe, które weszły nawet w fazę niewypowiedzianej wojny handlowej między USA a UE. Wykazano, że istotą problemu było to, że Trump używał wyższych ceł na towary sprowadzane z Europy jako instrumentu wywierania nacisku oraz realizowania polityki wymierzonej w UE. Wspólnota zaś reagowała cłami odwetowymi. W efekcie osłabiano spoistość sojuszu transatlantyckiego.

Published: February 2023

Space radiation particles will cause a variety of radiation effects on orbiting satellites, such as single event effects, total ionizing dose, displacement damage, etc. In response to these space radiation effects, BeiDou Navigation satellites M15/M16 operating in medium earth orbit (MEO) developed the first integrated monitor for high-energy proton and particle radiation effects, based on space particle radiation detection technology. This payload realizes the joint observation of the high-energy proton environment, particle radiation linear energy transfer spectrum, and total radiation dose in the MEO. According to the detection data, research on the characteristics and laws of the space particle radiation effects can be carried out, and the problem of spacecraft reliability verification in orbit can be solved from the causal chain. In this article, we have introduced the high-energy proton detector (energy range 3–300 MeV), including technical indicators, working principles, instrument design, and ground calibration.

Membrane damage and repair: a thin line between life and death
Authors: Barisch Caroline , Holthuis Joost C. M. , Cosentino Katia
Published: February 2023

Bilayered membranes separate cells from their surroundings and form boundaries between intracellular organelles and the cytosol. Gated transport of solutes across membranes enables cells to establish vital ion gradients and a sophisticated metabolic network. However, an advanced compartmentalization of biochemical reactions makes cells also particularly vulnerable to membrane damage inflicted by pathogens, chemicals, inflammatory responses or mechanical stress. To avoid potentially lethal consequences of membrane injuries, cells continuously monitor the structural integrity of their membranes and readily activate appropriate pathways to plug, patch, engulf or shed the damaged membrane area. Here, we review recent insights into the cellular mechanisms that underly an effective maintenance of membrane integrity. We discuss how cells respond to membrane lesions caused by bacterial toxins and endogenous pore-forming proteins, with a primary focus on the intimate crosstalk between membrane proteins and lipids during wound formation, detection and elimination. We also discuss how a delicate balance between membrane damage and repair determines cell fate upon bacterial infection or activation of pro-inflammatory cell death pathways.
The Dark Side of Insurance
Authors: Avraham Ronen , Porat Ariel
Published: February 2023

When insurance works properly it provides insureds with optimal incentives to prevent losses, alongside coverage for losses that could not be prevented efficiently. But insurance has an overlooked dark side to it as well. Insurers employ various tactics to shift losses to their insureds or to their victims in order to minimize their own costs instead of reducing their insureds’ losses. Worse, insurers might also act to increase or maintain long term risks, ensuring the future of the insurance business that can’t exist without risks. We focus on the incentives of insurers to engage in anti-competitive practices and trigger harmful behaviors of their insureds or third parties, in order to increase demand for insurance coverage. Policymakers should be aware and critical of insurers’ perverse incentives that counteract the interests of the insureds and society.
Retinal Dysfunction in a Mouse Model of HCN1 Genetic Epilepsy
Authors: Zhao Da , Pinares-Garcia Paulo , McKenzie Chaseley E. , Bleakley Lauren E. , Forster Ian C. , Wong Vickie H.Y. , Nguyen Christine T.O. , Scheffer Ingrid E. , Reid Christopher A. , Bui Bang V.
Published: February 2023

Pathogenic variants inHCN1are associated with a range of epilepsy syndromes including a developmental and epileptic encephalopathy. The recurrentde novo HCN1pathogenic variant (M305L) results in a cation leak, allowing the flux of excitatory ions at potentials where the wild-type channels are closed. The Hcn1M294Lmouse recapitulates patient seizure and behavioral phenotypes. As HCN1 channels are highly expressed in rod and cone photoreceptor inner segments, where they shape the light response, mutated channels are likely to impact visual function. Electroretinogram (ERG) recordings from male and female mice Hcn1M294Lmice revealed a significant decrease in the photoreceptor sensitivity to light, as well as attenuated bipolar cell (P2) and retinal ganglion cell responses. Hcn1M294Lmice also showed attenuated ERG responses to flickering lights. ERG abnormalities are consistent with the response recorded from a single female human subject. There was no impact of the variant on the structure or expression of the Hcn1 protein in the retina.In silicomodeling of photoreceptors revealed that the mutated HCN1 channel dramatically reduced light-induced hyperpolarization, resulting in more Ca2+flux during the response when compared with the wild-type situation. We propose that the light-induced change in glutamate release from photoreceptors during a stimulus will be diminished, significantly blunting the dynamic range of this response. Our data highlight the importance of HCN1 channels to retinal function and suggest that patients withHCN1pathogenic variants are likely to have a dramatically reduced sensitivity to light and a limited ability to process temporal information.

SIGNIFICANCE STATEMENTPathogenic variants in HCN1 are emerging as an important cause of catastrophic epilepsy. HCN1 channels are ubiquitously expressed throughout the body, including the retina. Electroretinogram recordings from a mouse model ofHCN1genetic epilepsy showed a marked decrease in the photoreceptor sensitivity to light and a reduced ability to respond to high rates of light flicker. No morphologic deficits were noted. Simulation data suggest that the mutated HCN1 channel blunts light-induced hyperpolarization and consequently limits the dynamic range of this response. Our results provide insights into the role HCN1 channels play in retinal function as well as highlighting the need to consider retinal dysfunction in disease caused byHCN1variants. The characteristic changes in the electroretinogram open the possibility of using this tool as a biomarker for this HCN1 epilepsy variant and to facilitate development of treatments.
A Comparative Study of Blasphemy Law in Indonesia and America: Religious and Legal Aspects
Authors: Puspaningrum Febrianti Dwi , Adhi Christoper Theovino
Published: February 2023

Article 29 of the 1945 Constitution states that the state is based on the One Godhead and the state guarantees the independence of each resident to embrace their own religion and to worship according to their religion and beliefs. The United States guarantees the freedom of worship and practice of religion for every citizen. This is stated in the first amendment to the United States Constitution which reads, "Congress does not make laws regarding the formation of a religion or prohibit freedom of religion; or restrict freedom of speech, or freedom of the press, or the right to peaceful assembly, and the right to petition for demanded compensation and lodged a complaint with the government." Based on the constitutions of the two countries, it is clear that freedom of religion and the right to embrace religion are protected by the state and everyone is obliged to respect the beliefs held. Although constitutionally freedom of religion has been regulated by each country, the potential for criminal acts of blasphemy still exists. The policies of two different countries are influenced by the government system adopted by Indonesia using the Criminal Code as a basis for punishment for perpetrators of blasphemy, while the United States does not federally regulate blasphemy, but states are given the authority to provide protection for their citizens by making legal products that impose penalties for blasphemy.
A Discourse of Capital Punishment in the Islamic Law and Human Rights Law
Authors: Saputro Muhammad Eko , Febriansyah Andhika , Putri Faradisya Diandra
Published: February 2023

The death penalty for convicts is an age-old subject to a lot of criticism from various quarters. The implementation of the death penalty is considered inconsistent with the principles of human rights which are principles of international law where countries cannot refuse because of common alignments, namely the right to life. The punishment of m ati raises pros and cons in Indonesian society, some agree with this punishment because the death penalty intends to protect the public interest and not a few oppose it, they argue that the death penalty is contrary to human  rights principles. This fact encourages the author to examine the implementation of the death penalty based on human rights and Islamic law, this is because the majority of Indonesians are adherents of the Islamic religion and also because the implementation of the death penalty is still carried out in Indonesia in certain crime cases. To examine this conflict, the author uses a normative juridical method with the conclusion that the death penalty is contrary to human rights because it eliminates the right to life for a person, but the implementation of the death penalty can be justified if the implementation of the death penalty is carried out in order to protect human rights and is also imposed on convicts who commit crimes beyond the limits stipulated in the legislation.
The labor market and employment during the war: state and prospects
Authors: Ivanenko Olena
Published: February 2023

The article deals with changes in the employment market taking place during the war, its state and future prospects. The changes that have taken place in the employment market in the 21st century, in particular, the transformation of its structure and modes of labor activity due to globalization processes, and recently the practices of remote work through Internet networks and digital platforms that have become familiar and traditional and have grown during quarantine restrictions, after February 24, turned out to be perhaps the most stable and tenacious form of employment for the population of Ukraine. Improving the legal framework for these forms of employment minimizes job losses and guarantees earnings, including the IT sector, where Ukraine is not the last actor not only during the war, but also in the post-war perspective. Large-scale destruction of industrial and other enterprises, transport and other infrastructure in the country, the curtailment of small and medium-sized businesses, the outflow of skilled labor abroad, an increase of the number of internally displaced persons, etc. dealt a tangible blow to the employment market, causing an imbalance between the supply and demand for jobs, the fall of wages, and increased impoverishment among the most vulnerable segments of the population. Based on the materials of sociological research and public opinion polls the article shows the dynamics of changes in the employment market during the war and identifies prospects if hostilities in the country drag on for a long time. At the same time, in order to counteract this, the state is trying to take all possible measures to minimize the negative consequences of the war and help maintain the human potential of Ukraine by introducing various support programs. Taking into account the experience of the post-war reconstruction of the Balkan region countries can serve as a good example of how to avoid miscalculations in this direction.

Remaja, Seksualitas dan Manajemen Nafsu (Tafsir Tematik Q.s. Yusuf [12]: 22-23)
Authors: A’raaf Muhammad , Suparman Taufik Ramadhan
Published: February 2023

This paper tries to reveal the method applied by Prophet Yusuf in controlling lust. In previous studies, interpreters and researchers did not associate verses 22-23 of surah Yusuf with adolescents and sexual desires, especially at that time and only focused on tarbawi (education) values. This discussion is necessary considering that the Prophet Yusuf did manage to resist the temptation of sexual desire and save him from destruction. The method used in this study is qualitative with an analysis interpretation approach. In these verses, it is concluded that in managing lust, there are at least three foundations and three ways that need to be owned and done by teenagers to subdue lust.
Biological functionality and characteristics of Jerusalem artichoke (Helianthus tuberosus L.) tuber extracts
Authors: Afoakwah N.A. , Zhao Y. , Dong Y.
Published: February 2023

Jerusalem artichoke tuber extracts (JAE) bioactivity including anticancer, antimicrobial, and digestion-inhibiting properties were investigated. The findings showed that the extracts were able to inhibit cancer growth in the HT-29 colon cancer cell line (HT-29 cc cell line) in a dose-dependent form. The suppression of cell proliferation rose to about 78.05 ± 3.9 percent at a dose of 250 μg mL−1. The Annexin V assay showed dose-dependent DNA fragmentation and detected late apoptotic induction in the HT-29 cc cell line. Depending on the concentration, the extract was able to stop the cell cycle in the HT-29 cc cell line at the G1 phase. Also, JAE prevented the HT-29 cc cell line growth, which resulted in programmed cell death. Additionally, the extracts are potential antibacterial agents and may inhibit lipase and α-amylase.
Identifying Roots: Alex Haley and the Anthropology of Scriptures
Authors: Newton, Jr. Richard W.
Published: February 2023

Identifying Roots presents a cultural history of Alex Haley’s Roots, examining the strategy and tactics Haley employed in developing a family origin story into an acclaimed national history. More than an investigation into Alex Haley’s legacy, Identifying Roots unearths the politics of beginnings and belongings. While we all come from somewhere, this book examines the terms on which our roots can work as a tradition to embrace rather than a past to leave behind. And it investigates why some of the texts we read also seem to read us back. Identifying Roots invites readers to reimagine the way we tell stories. A provocative study that draws upon Black studies, the history of religions, and anthropology, this book underscores the social drama and dynamics that define our scriptures. Nimbly moving between the stories of Alex Haley, his characters, and the world that received them, Newton reminds us that our roots are stories of consequence.
A NOVEL METHOD TO ANALYZE THE SELF-EXCITED AND PULSED T-BURNER EXPERIMENTAL DATA AT WIDE PRESSURE AND FREQUENCY RANGES
Authors: Ganesan S. , Chakravarthy S. R. , Chandran B. S. Subhash
Published: February 2023

This paper describes the extended work for the methods of analysis of the T-burner experimental data which was published earlier this year. The combustion instability in solid rocket motors is mostly addressed using a T-burner by the measurement of response function for a given solid propellant. The experimental data could be reduced to the required response function by many methods. Six different methods of analyzing the experimental self-excited T-burner data at 1 MPa were presented in the previous work which consisted of Perry's method, Culick's method, and an exponential method with different combinations. It was observed that Culick's method is better when compared to the other methods. However, the recent investigations revealed that Culick's method has issues when analyzing the response data at higher pressures and for pulsed tests. This paper revisits those methods, compares them with new methods, and finally arrives at a method which is acceptable for any pressure and any test result (self-excited/pulsed). It was observed that the modified Perry method is better for all the different kinds of T-burner data to deduce the combustion response at different pressures and frequencies. The advantages of this method are brought out. This method is working better than Culick's method and is useful in all the T-burner test data analyses from which the stability prediction of solid rocket motors could be developed.
Effect of wall sheathings on seismic behaviour of phosphogypsum-filled CFS shear walls
Authors: Hu Song , Huang Yong , Zhou Li
Published: February 2023

To improve the seismic behaviour of cold-formed steel (CFS) walls, a novel infilled CFS wall covered with different wall sheathings (gypsum wallboard, oriented strand board and fibre cement board) was assessed. Four full-scale specimens were tested under cyclic lateral loads to investigate the impacts of the wall sheathings on the seismic performance of the CFS wall. The failure process, failure mode, load–displacement curve, strength degradation, stiffness degradation, energy dissipation, deformation and strain variation of the walls were investigated. The failure modes of the walls were found to be failure of the connections between the CFS frame and the sheathing as well as crushing of the infill material. Compared with a specimen without sheathing, the peak load and lateral stiffness of the walls with sheathing were increased by 1.25–1.72 times, indicating that the sheathings played an important role in the lateral resistance of the wall. An analysis model and formulas for predicting wall lateral stiffness were developed. Comparisons between the calculations and experimental data showed that the proposed theoretical method was able to predict the lateral stiffness of the infilled CFS walls accurately.

Currently, the economy of the Republic of Kazakhstan is developing at a rapid pace. Of great importance in the economy of the Republic of Kazakhstan are industries that are associated with the extraction and processing of natural resources, especially oil and gas, which the Republic of Kazakhstan is rich in. Oil production is a multi-stage production process that includes exploration, drilling and construction of wells, their repair, purification of produced oil from water, sulfur and paraffin and impurities. Oil production facilities in the world, including in Kazakhstan, are classified as hazardous production facilities that require strict compliance with production safety requirements. At the same time, the extraction and processing of natural resources is associated with difficult and harmful working conditions, hazardous production factors, which, if safety requirements are not observed, can lead to industrial injuries, occupational diseases and other undesirable consequences. The international organization OPEC+ exists to develop a common production policy, maintain stable oil prices, ensure stable supply to consumers, and increase efficiency through investment in the oil industry. OPEC+ represents a community of participating countries, coordinating actions and strategies for exporting oil around the world. Today, OPEC countries have a total of about 80% of oil reserves. The value in the field of production reaches 40%, while global oil exports consist of OPEC + supplies for half. At a meeting of the government of the Republic of Kazakhstan, the results of oil production in 2021 were reported, which amounted to 85.7 million tons and 67.6 million tons for export. In 2021, the volume of reduction in oil production in oil exporting countries (OPEC +) was reviewed monthly. The Republic of Kazakhstan planed to maintain the volume of oil production in 2022 at the level of 87 million tons [1].

Proton exchange membrane fuel cell (PEMFC) is a well-known energy converter that has low greenhouse gases (GHG) emission, low operating temperatures, and high power density. PEMFC operates on hydrogen (H2) as fuel, and oxygen (O2) as oxidant. Inverse electrolysis occurs between the oxidant and the fuel. Then, water (H2O) forms as their by product. Practically, O2 is supplied from the free air which contains not only oxygen but also other gases such as sulphur dioxide (SO2), and nitrogen oxides (NOx). Meanwhile, the H2 fuel may contain traces of carbon monoxide (CO) as a result from its previous reforming process. This makes PEMFC susceptible to disruption from these particles. These contaminating gases from the free air occupy the reacting sites originally meant for O2 and react with hydrogen ions instead of oxygen ions. While minute CO traces from the fuel occupies the reacting sites for H2 and react with oxygen ions instead of hydrogen ions. Consecutively, the energy output from the PEMFC will be short from its expected numerical value hence a less efficient PEMFC. Hence, this paper reviews recent research on PEMFC under the impact of cathode and anode side contaminants via experimental and numerical works. It is found that CO has more effect to the cell compared to CO2. SO2 and CO contaminates the catalyst layer while NOx does not. In addition, PtRu/C shows more resistance to contamination compared to traditional Pt/C. This comparative review serves to find out potentials in improving PEMFC operation and solving its mitigation strategies.

A composite perovskite Ba0.5Sr0.5Co0.8Fe0.2O3−δ-Sm0.2Ce0.8O1.9 carbonate (BSCF-SDCC) coating was investigated to enhance the performance of SUS 430 stainless steel as interconnect material for solid oxide fuel cells (SOFCs). BSCF-SDCC powder was successfully obtained by low-speed wet milling method from commercial BSCF, SDC, and binary carbonates. The developed BSCF-SDCC powder were heat-treated 600 °C for 90 min, and then characterized by X-ray diffraction (XRD) and field-emission scanning electron microscopy (FESEM) equipped with energy-dispersive spectroscopy (EDS). FESEM revealed better morphology of BSCF-SDCC powder with heat treatment. However, XRD analysis showed the destruction of BSCF phase in the BSCF-SDCC powder after heat treatment at 600 °C. Moreover, electrophoretic deposition (EPD) of BSCF-SDCC powder in an ethanol-added dispersing agent suspension was investigated under 10 volt 10 minutes by 10 g/l. The coated samples were then heat-treated at 600 °C. The coated samples were characterized by comparing between the samples with and without heat treatment based on XRD, SEM-EDS, and area specific resistance (ASR) analyses. XRD analysis indicated BSCF phases disappeared for the samples with heat treatment. The heat-treated sample performed better coating morphology and fewer pores. The samples underwent 500 hours of air oxidation at 600°C, and ASR was measured by DC 2-point method during in situ oxidation process. The coated sample with heat treatment at 600 °C exhibited excellent low area-specific resistance reading of below 0.1 Ωcm2, which is an essential requirement for interconnect materials. After 500 h of oxidation, the XRD patterns revealed stable phase and maintained good coating morphology.

The profusely used tools of operational management research in lean manufacturing context include roadmap, conceptual model, implementation frameworks, descriptive planning and assessment checklist. Out of these, an implementation framework development in lean manufacturing sector is common, but faces quandary regarding its development, consolidation and validation – thereby confirming the requirement of availability of succinct platform that aids in research methodology development. The aim of this research is to attain a clear research context, achieved accordingly by detailed literature review study that would subsequently aid in developing a generic research methodology design framework. Concomitant to it, the four layers, the layers of research onion were discussed; followed by selection of appropriate methods for development of research methodology in order to arrive at implementation frameworks. It was observed that for the methodology development, the philosophy of pragmatism is highly suitable, followed by abductive logic, in case of technique, mixed mode research is best, whereas in strategy selection, case study strategy is the most suitable due to its multi-functional ability of in-depth operational study. In addition to that, the mixed-mode approach carries the ability of comparative qualitative and quantitative research through longitudinal and cross-sectional case study respectively. Furthermore, the data collection processes were discussed in relevance to the research objective, which culminated in the formation of a detailed research methodology which has been divided into three major stages of research context and approach, framework development and validation, resulting in attaining implementation framework through literature review, longitudinal case study and cross-sectional case study respectively. The major strength and contribution of this research study is the development of one concise research methodology that is considered as the paradigm shift and a clear innovation towards this field.

Hybrid Convolutional Neural Network Method for Robust Brain Stroke Diagnosis and Segmentation
Authors: YALÇIN Sercan
Published: February 2023

Artificial intelligence with deep learning methods have been employed by a majority of researchers in medical image classification and segmentation applications for many years. In this study, hybrid convolutional neural network (CNN) model has been proposed for diagnosing of brain stroke from the dataset consisting of the computed tomography (CT) brain images. The model inspired from C-Net consists of multiple concatenation layers of the networks, and prevents the concatenation of convolutional feature maps to evince the mapping process. The structures of the convolutional index and residual shortcuts of the INet model are also integrated into the proposed CNN model. In output layer of the model, it is split into two classes as whether there is a stroke or not in a brain image, and then the region of the stroke in the image is segmented. Tremendous analyzes have been conducted in terms of many benchmarks using Python programming. The proposed method shows better performances rather than some other current CNN-based methods by 99.54% accuracy and 99.1% Matthews correlation coefficient (MCC) in the diagnosis of brain stroke. The proposed method can alleviate the work of most medical staffs and facilitate the process of the patient’s remedy.
