Possible Psychosocial Factors Having an Impact on The Worldviews and Political Orientation in Turkey
Authors: Selçuk Fatma Ülkü
Published: June 2023

This research investigates psychosocial paths towards worldviews and political orientation in view of basic human values, Big Five, Dark Triad, and early maladaptive schemas with an adult sample from Turkey through individual mediation analyses. Venn diagrams are used to visualize possible convergence and divergence points for selected variables. Rightwing political orientation is correlated with vulnerability to harm and illness, entitlement, Machiavellianism, religiosity, tradition, security, conformity, rightwing authoritarianism (RWA) and social dominance orientation (SDO) positively; and universalism, self-direction, hedonism, belief in a dangerous world (BDW) negatively, but is not correlated with belief in a competitive jungle world (BCJW). Where early maladaptive schemas are the predictors, benevolence, universalism power, achievement, psychopathy, Machiavellianism concerning BCJW; emotional stability, extraversion, security, Machiavellianism concerning BDW; agreeableness, intellect/imagination, universalism, power, Machiavellianism, narcissism, psychopathy, BCJW concerning SDO are among the most repeated individual mediators. The paths from the earlier maladaptive schemas towards RWA and rightwing political orientation are more diverse than the ones towards BCJW, BDW, and SDO. A wider range of predictors and mediators has an effect on BCJW compared to other outcome variables; including the rightwing political orientation, comprising the narrowest range. Mostly two, at times three-four patterns occurred during the individual mediation analyses.
PRAKTIK KARTEL DALAM PERSPEKTIF HUKUM BISNIS SYARIAH
Authors: Ramadhani Marina , Habib Muhammad Alhada Fuadilah
Published: June 2023

Abstract: The practice of cartels is a type of practice that is prohibited in Law no. 5 of 1999 concerning Antimonopoly, because it is an agreement that aims to dominate the market, by regulating the production and/or marketing of goods and/or services, and may result in monopolistic practices and unfair business competition in that market. Formulated by the rule of reason, which is regulated in Article 11 of Law no. 5 of 1999 concerning Antimonopoly. If relevant, the practice of cartels is included in the form of syirkah (cooperation) in muamalah fiqh. However, based on sharia business law, the practice of cartels is different from syirkah (cooperation) according to Islamic law, because the ultimate goal of cartel practices is to set prices for certain products and limit the availability of products in the business competition market, resulting in unfair and unfair competition. for other companies, and to benefit members who are involved in the practice of the cartel, which is against the rules in the Qur'an and Al-hadith based on the word of Allah.

Abstrak: Praktik kartel merupakan jenis praktik yang dilarang dalam Undang-undang No. 5 Tahun 1999 Tentang Antimonopoli, karena merupakan perjanjian yang bertujuan untuk menguasi pasar, dengan mengatur produksi dan/atau pemasaran suatu barang dan/atau jasa, dan dapat mengakibatkan terjadinya praktik monopoli dan persaingan usaha tidak sehat pada pasar tersebut. Dirumuskan secara rule of reason, yang diatur pada Pasal 11 Undang-undang No. 5 Tahun 1999 Tentang Antimonopli. Jika direlevansikan praktik kartel termasuk dalam bentuk syirkah (kerja sama) dalam fiqh muamalah.  Namun berdasarkan hukum bisnis syariah bahwa praktik kartel berbeda dengan syirkah (kerja sama) menurut Syariat Islam, karena tujuan akhir dari praktik kartel adalah menetapkan harga dari produk tertentu, serta membatasi ketersediaan produk di pasar persaingan usaha, sehingga mengakibatkan timbulnya persaingan yang curang dan tidak adil bagi perusahaan yang lain, dan untuk menguntungkan anggota-anggota yang terlibat dalam praktik kartel tersebut, yang bertentangan dengan aturan dalam Al-quran dan Al-hadits berdasarkan firman Allah.

Authors: Revit Jayanti , Ferdian Wildan , Septiawan Debree
Published: June 2023

Background Sampling in bronchoscopy can lead to acute consequences, such as intrabronchial bleeding, bronchospasm, and pneumothorax. Bronchoscopies make patients uneasy because they fear discomfort and difficulty breathing. Hypnotherapy, music therapy, and aromatherapy can help during bronchoscopies. Musicure is considered to assist people to grow well by sending "passive" musical impulses.

Objective The goal of this study was to see how well musicure helped bronchoscopy patients deal with pain.

Methods A quasi-experimental design with a pre-test, post-test, and control group was used. Patients with lung illness will undergo bronchoscopy and consecutive sampling at the Dr. Moewardi Surakarta Hospital in February-March 2020. The study subjects were divided into a treatment group with Musicure and a control group without music. Both groups were assessed with pain visual acuity score (VAS)  at baseline and after bronchoscopy.

Results A total of 32 subjects with lung diseases whom bronchoscopy in this study. The treatment group showed a decreased pain VAS scale (-14.71±12.31). The treatment group pre-test pain score obtained 31.76±12.86, and the VAS post-scale average of 17.06±12.63. The changes in the VAS scale post-pretreatment group showed a decrease in average -14.71±12.31. The treatment group (p=0.002) obtained a p<0.05, which means that the treatment group experienced a significant change in the VAS scale. There was a significant difference compared to the control (p<0.05).

Conclusion Musicure is effective in inhibiting perception of pain that it will lower the VAS scale,  therefore decreasing pain score.  Pain in patients who undergo bronchoscopy will be more controlled, which makes it easier to act and decrease side effects after the action.

Angažirana filozofija – slučaj estetike i filozofije umjetnosti
Authors: Vidmar Jovanović Iris
Published: June 2023

U ovom radu bavim se pitanjem angažirane filozofije s naglaskom na estetiku i filozofiju umjetnosti. Pozivajući se na neke konkretne probleme o kojima se raspravlja unutar ovih domena – napose problem klimatskih promjena, ekološke krize i nemoralne umjetnosti – pokazujem da filozofija može biti angažirana na dva načina: (i) u svojoj težnji za propitkivanjem društvene zbilje, kulture, ljudskog iskustva i strategija koje čovjek koristi da bi u tom iskustvu uvidio smisao i vrijednosti; (ii) u težnji da kroz svoj doprinos razumijevanju takve zbilje i tog iskustva doprinese boljitku pojedinca i društva. Rad započinjem ukazujući na povezanost filozofskih pitanja i osnovnih intelektualnih težnji čovjeka kao društvenog i kulturnog bića, ali i autonomnog spoznavatelja i vrednovatelja. U drugom dijelu odgovaram na dva prigovora koja se mogu uputiti angažiranoj filozofiji: (i) prigovoru koji ukazuje na nedostatak konsenzusa među filozofskim odgovorima (problem neslaganja) i (ii) prigovoru koji ističe irelevantnost filozofskih debata za naše društvene prakse.
Zašto studirati filozofiju?
Authors: Škerbić Matija Mato
Published: June 2023

Pitanju zašto studirati filozofiju autor pristupa s afirmativnog gledišta te u radu argumentira pro philosophia, odnosno opravdava i promiče mogući upis studija filozofije u obzorju današnjice razmatrajući njegove izvanfilozofijske benefite. Autor tako progovara iz specifične perspektive te studij filozofije sagledava u oportunističkom i instrumentaliziranom rakursu. Naime, ne razmatra studij kao takav, njegovu filozofijsku opravdanost i kvalitetu, nego traži njegove potencijale u i za svijet današnjice. Dakle, ne za poslove poput nastavnik filozofije ili akademski filozof, već zapravo gotovo sve druge. U tom smislu, autor razrađuje deset mogućih benefita studija filozofije: (1.) razvoj kritičkog, logičkog i refleksivnog, (2.) skrbnog i (3.) kreativnog mišljenja; (4.) prepoznavanje i formuliranje (esencijalnih) pitanja; (5.) donošenje kvalitetnih odluka (engl. decision making) i zauzimanja stavova; (6.) razvijanja vještine rješavanja problema (engl. problem solving); (7.) vršenje etičke refleksije; (8.) pomaganje u prepoznavanju životnih vrjednota; (9.) promicanje ljudskog procvata i potrage za smislom; te zapravo (10.) vrši pripremu za niz mogućih zaposlenja izvan filozofskih struka.
Proroci židovske »protukulture« – Martin Buber, Erich Fromm i Abraham Joshua Heschel
Authors: Akrap Domagoj
Published: June 2023

Rad prikazuje nastanak posebne židovske protukulture na prijelazu iz 1960-ih u 1970-e godine prošlog stoljeća u Sjedinjenim Američkim Državama kao posljedice antiratnog pokreta i pokreta za građanska prava. Dijaloška filozofija Martina Bubera, humanizam Ericha Fromma i religiozni egzistencijalizam Abrahama Joshue Heschela bitno su oblikovali ideje mlade generacije Židova i utjecali na njihovu želju za obnovom židovskog života. Iako su se koncepcijski i stilski razlikovali, ovoj trojici mislioca zajednička je bila neumorna kritika nesnošljivosti sadašnjice i borba za pravednije društvene odnose. Bez obzira radi li se o Buberovu društvu izgrađenom na slobodnom udruživanju, Frommovu humanističkom socijalizmu ili Heschelovu slobodnom društvu prožetom religijom – frustriranoj i izgubljenoj mladoj generaciji ponudili su odgovore i pokazali im put k izrazito željenoj »duhovnoj revoluciji«, zadobivajući na taj način uloge proroka.
Koncept estetike ružnoga na primjeru umjetnosti radikalne enformelne apstrakcije
Authors: Gaj Ristić Barbara
Published: June 2023

Unutar umjetnosti radikalnog enformela nalazimo djela izražene nepikturalnosti, nesemantičnosti i nereferencijalnosti, kao i težnju prema entropiji, raslojavanju i razjedinjavanju forme kroz destruktivne procese deformiranja, perforiranja, urezivanja, grebanja, gomilanja struktura i masa, fragmentacije, skidanja slojeva i spaljivanja. U ovom je radu naglasak stavljen na teoretske modele tumačenja radikalnog enformela kroz koncepte estetike ružnoće, odnosno brutalne estetike, kao što su: (1) deformacija, (2) disfiguracija, (3) neformnost, i (4) entropija – na primjerima enformelnog stvaralaštva Ive Gattina, Eugena Fellera i Marijana Jevšovara, koji su proizašli iz njihovih svjetonazora prema umjetnosti i slici. Umjetnici su intencionalno stvarali slike koje nisu »lijepe« suprotstavljajući se klasičnim vrijednostima umjetnosti i ljepote kroz opozicijski i negacijski pristup, nihilizam, destrukciju, deformiranje i poništavanje slikarske površine kao vidovima anti-estetike.
Strengthening ZOPACAS: the Maritime Safety Roadmap for the South Atlantic
Authors: Borges Marcio
Published: June 2023

Population growth poses one of the greatest challenges for human survival in the 21st Century and, increasingly, man is turning to the sea for food and energy. As the ocean has no physical boundaries, it is inevitable that some of these activities will affect the seashore and jurisdictional waters of coastal States, negatively affecting those nations’ territorial waters, with all the economic and social ramifications that entails. Recent studies point to most threats to maritime jurisdictions coming from undetected acts perpetrated on the high seas. Therefore, this article looks at potential threats in this domain and measures to mitigate those threats, in full compliance with the provisions of the United Nations Convention on the Law of the Sea. That fact, and the limitations imposed by international law, make it impossible for any one country to address these issues alone. Increasingly States need the support of hemispheric alliances, such as the Organization of American States, and transboundary water agreements such as the South Atlantic Peace and Cooperation Zone. Leveraging those alliances and agreements to reinforce maritime safety is the surest way to foster cooperation among developing nations, including those with coasts along the South Atlantic, and to prevent maritime threats from undermining their future.
Arctic geoeconomy and new trade routes: Sino-Russian logistics projects and strategic investments in the region
Authors: Jaeger Bruna , Chrystello Lucas
Published: June 2023

The Arctic Sea melt tends to worsen throughout the 21st century. If, on the one hand, it is seen as an environmental catastrophe, on the other hand, it is also seen as an economic advantage by its neighbors. As the melting takes place, the more accessible the Arctic becomes, making it viable to explore natural resources and to build and consolidate a trade route capable of surpassing the current trade routes connecting Asia and Europe, in terms of time and savings. Thus, this work focuses on answering the following question: how does the Arctic melting impact the geoeconomy of international trade? Using the perspective of geoeconomic theory, introduced and developed by Edward Nicolae Luttwak, Robert Blackwill and Jennifer Harris, this paper aims to conceptualize global warming, compare current routes with the advantageous North Sea route from data collection and to critically analyze sino-russian cooperation in consolidating their ongoing commercial maritime projects in the Arctic region.
Information as a weapon of mass disruption: from information disorder to cognitive warfare
Authors: Pace Rodrigo , Coelho Emilio
Published: June 2023

The aim of this article is to understand how the information disorder influences and sets the stage for using the information as a weapon. It claims that bearing in mind the means, the message, and the audience, information can be utilized as a weapon of mass disruption. The paper examines the chaotic environment that surrounds the informational sphere, the information disorder. It analyses why it is possible to assert that information is a weapon of mass disruption, and it presents definitions to support the analysis, beginning with the meaning of disruption and conceptualizing the term “weapons of mass disruption”. The paper brings another concept that has evolved recently, the “Cognitive Warfare”. The essay states that information disorder background supports and provides the necessary conditions to the use of information as a weapon of mass disruption. At the same time, this weaponization itself feeds back and boosts disorder, in a vicious cycle that represents a direct threat to global security. It concludes that when introduced into a disordered world fueled by emerging technology and social media, information may cause harsh damage in a culture or government by exploring manipulation and the vulnerabilities and cognitive biases of the human brain.

A turizmusipar jövőbeni megítélése szempontjából elsődleges fontosságú lépésnek számít, hogy a több milliárd néző által figyelemmel kísért nagyrendezvényeknél (az olimpiáknál és a Forma–1-es futamoknál) minél jobban érvényesüljenek a fenntarthatósági törekvések. Az olimpiák és Forma–1-es futamok zöldülései hozzájárulnának a felelős turistatípus kialakításához is. A nemzetközi sportközösség 2018-ban indította el a „Sports for Climate Actiont”, vagyis a sportok a klímaakcióért kezdeményezést. Ehhez a kezdeményezéshez kapcsolódott 2018-ban a phjonghcsangi téli olimpia, ami már akkor a legzöldebb olimpiaként hirdette magát. A 2022-ben kezdődő pekingi téli olimpiára Kína már teljes karbonsemlegességet ígért, ezzel utat mutatva a többi olimpia szer­vezésének is. A Forma–1 (a számításaink szerint) a világon a legnagyobb karbonlábnyommal rendelkező nagyrendezvény, nem történnek látványos előre lépesek a zöld versenysport előre mozdításának az ügyében. Vizsgálataink során utat szeretnénk mutatni, hogy milyen lehetséges alternatívák vetődhetnének fel a rendezvénysorozat zöldítése során. A kutatásunk során a Forma–1-es ver­senyek gazdasági, társadalmi és környezeti hatásait elemeztük a fenntarthatóság szempontjából. A Forma–1 Magyar Nagydíjon készült elemzéseink alapján általános következtetéseket vontunk le a versenysorozat egészére vonatkoztatva.

A fenntartható energiagazdálkodás a Szakképzés 4.0 stratégia és az Európai Unió célkitűzése alapján egyaránt elvárásként fogalmazódik meg a szakképző intézmények számára. Az iskolákban a nevelő-oktató munkában is fontos figyelmet szentelni e területnek. A fogyasztói társadalom korában komoly kihívás a mindennapokban a környezet- és a természetvédelem. Az iskolák feladata sokszínű, hiszen tudatos, környezetbarát fogyasztókat, munkavállalókat kell képezniük, illetve működésük során is sok új szempontot kell figyelembe venniük fenntarthatóságuk fejlődéséhez. Két intézmény esetében vizsgálom az emberi, társadalmi, természeti, gazdasági erőforrásokon belül az oktatás vonatkozásában könnyen nyomon követhető mutatókat.

Calibration and prediction uncertainty analysis of a hydraulic-water quality coupling model using a modified moth-flame optimizer
Authors: Wang Qianyang , Yu Jingshan , Zhang Xueyu
Published: June 2023

There is a lag between the latest development of the heuristic algorithm and its application in environmental model calibration. Besides, heuristic algorithms are usually thought to be deterministic and can hardly account for the equifinality of different parameters. To fix these limitations, we proposed a novel elite opposition-modified moth-flame optimizer (EOMFO) and presented a scheme combining it with the frequency statistical method for auto-calibration and prediction uncertainty estimation. A case study of a hydraulic-water quality coupling model was provided, in which the urban non-point source ammonia nitrogen (NH3-N) and total phosphorus (TP) were simulated. Compared with the benchmark particle swarm optimizer (PSO) and MFO, EOMFO has better global optimization ability and can obtain behavioral samples with higher quality for sensitive parameters. Regarding the calibration performance, EOMFO performed well in both the NH3-N and TP simulations (Nash–Sutcliffe efficiency around or greater than 0.5 and R greater than 0.7) and outperformed benchmark algorithms for both the deterministic prediction and uncertainty band prediction. The generated uncertainty band bracketed the majority of TP observation points, although it is not in good agreement with NH3-N observations due to several potential reasons. With this scheme, a more efficient and robust calibration process is expected.
Semi-automatic Framework for Voxel Human Deformation Modeling
Authors: Gao Yangchun , Xu Xu , Li Congsheng , Liu Jie , Wu Tongning
Published: June 2023

Background:

With the advancement of computer and medical imaging technologies, a number of high-resolution, voxel-based, full-body human anatomical models have been developed for medical education, industrial design, and physics simulation studies. However, these models are limited in many applications because they are often only in an upstanding posture.

Objective:

To quickly develop multi-pose human models for different applications. A semi-automatic framework for voxel deformation is proposed in the study

Methods:

This paper describes a framework for human pose deformation based on three-dimensional (3D) medical images. The voxel model is first converted into a surface model using a surface reconstruction algorithm. Second, a deformation skeleton based on human bones is defined, and the surface model is bound to the skeleton. The bone Glow algorithm is used to assign weights to the surface vertices. Then, the model is deformed to the target posture by using the Smoothed Rotation Enhanced As-Rigid-As-Possible (SR-ARAP) algorithm. Finally, the volume-filling algorithm is applied to refill the tissues into the deformed surface model.

Results:

The proposed framework is used to deform two standing human models, and the sitting and running models are developed. The results show that the framework can successfully develop the target pose. When compared to the results of the As-Rigid-As-Possible algorithm, SR-ARAP preserves local tissues better.

Conclusion:

The study proposes a frame for voxel human model deformation and improves the local tissue integrity during deformation.
A Comprehensive Review on Herbal Nanoparticulate System through
Intranasal Route for Management of Congenital-Neuro Zika Therapy
Authors: Joshi Deepika , Sharma Priya
Published: June 2023

Backgroud:

An arbovirus called the Zika virus is spread by Aedes mosquitoes. The Zika virus (ZIKV) epidemic that has recently spread over the Western Hemisphere (the Americas and the ongoing outbreak in Brazil) is now recognised as one of the main causes of neurologic disease and other potential neurologic consequences.

Methods:

There are currently no antivirals available, and vaccines are only available for some. Currently, only symptomatic treatment is available. Various herbal plants, vegetables, fruits, flowers, and microbes have been documented to exhibit antiviral activities possessing good tolerability and minimal side effects. Polyphenols and other phyto-constituents have been extensively studied against arboviruses and have demonstrated promising results.

Results:

This review article focuses on a potential new herbal formulation with strong antiviral properties against the current zika virus and accompanying symptoms, with intranasal administration as the preferred method for treating neurological symptoms.

Conclusion:

Natural anti-viral therapy plays an important role in contributing to antiviral drug development and in reducing the global infection burden of arboviruses.

Osun State, Nigeria
Authors: Olowe O.A. , Adeagbo O. , Olaitan P.B. , Olowe R.A. , Opakunle T. , Eniade O.D. , Olarinmoye A.T. , Atolagbe J.
Published: June 2023

Introduction:

This study focused on estimating the probability of survival and the specific
time to survival from COVID-19 among patients who had COVID-19 in Osun state, Nigeria. Also, we
examined some factors associated with the time to survival among COVID-19 patients in Osun state,
Nigeria.

Methods:

The retrospective data of 2596 records of COVID-19 patients in Osun state were analysed in
this study. The outcome variable was the “COVID-19 treatment outcome (survived=1, dead=0)”. The
time date used in the survival analysis was treatment duration (in days). The explanatory variables
were demographic characteristics, type of health facility, vaccination status, symptoms, and mode of
admission. The descriptive statistics was computed and presented. Kaplan Meier was used to estimate
the median time to survival. Bivariate analysis and multivariate analysis were done using the Log-Rank
test and Cox regression, respectively. P values were set at P<0.05.

Results:

The mean age was observed to be 40 (SD=17.51) years, ranging from mostly, 2 months to 98
years old. More (56.1%) of the participants were males. Most (99.5%) of them were Nigerians. Only
1.4% were vaccinated. The survival rate from COVID-19 was 98.1% in Osun State. The median time
for survival was 14 (IQR= 14- 16) days. COVID-19 reduces as the number of days for being on treatment
increases. Unvaccinated (HR=0.93, 95%CI: 0.43-2.03) and those whose vaccination status was
unknown (HR=0.52, 95%CI: 0.37-0.74) were less likely to survive COVID-19 diseases.

Conclusion:

The Survival rate was high, the observed median time to survival was 14 days, and the
probability of survival reduces as the number of days of being on treatment for COVID-19 increases.
Also, gender, vaccination, type of care, and ethnicity were associated with survival time. Similarly,
unvaccinated and inpatients were less likely to rapidly survive COVID-19. This study recommends

Authors: Ou Christine , Corby Kathryn , Booth Kelsey , Ou Hui-Hui
Published: June 2023

BACKGROUND

The declaration of the COVID-19 pandemic led to public health restrictions that impacted the lives of people across the globe. Parents were particularly burdened with balancing multiple responsibilities, such as working from home while caring for and educating their children. Alcohol use among parents is an area that warrants further exploration.

OBJECTIVE

This study aimed to investigate patterns of parental alcohol consumption during the COVID-19 pandemic, focusing on relative changes in the frequency and quantity of alcohol use compared to prepandemic use, nonparent adult samples, or both.

METHODS

A scoping review informed by the methodology of Arksey and O’Malley explored patterns of parental alcohol consumption during the COVID-19 pandemic. Searches were conducted in CINAHL, Ovid MEDLINE, PsycINFO, and Web of Science. Search terms were created using the Joanna Briggs Institute framework of Population, Concept, and Context, with the population being parents and the concept being alcohol consumption during the COVID-19 pandemic.

RESULTS

The database search yielded 3568 articles, which were screened for eligibility. Of the 3568 articles, 40 (1.12%) met the inclusion criteria and were included in the scoping review. Findings indicated the following: (1) having children at home was a factor associated with parental patterns of alcohol use; (2) mixed findings regarding gender-related patterns of alcohol consumption; and (3) linkages between parental patterns of alcohol use and mental health symptoms of stress, depression, and anxiety.

CONCLUSIONS

This scoping review revealed heterogeneous patterns in parental alcohol use across sociocultural contexts during the COVID-19 pandemic. Given the known harms of alcohol use, it is worthwhile for clinicians to assess parental drinking patterns and initiate conversations regarding moderation in alcohol use.

Published: June 2023

The current study aims at assessing the effect of using cold-bonded fly ash based artificial lightweight aggregate (ALWA) as an internal curing (IC) agent on the compressive strength and drying shrinkage of a typical super-sulfated cement (SSC) produced with a mixture of 85% slag, 10% gypsum, and minor amount of 5% blended Portland cement (PCB). The ALWA was used as partial replacement of fine aggregate (FA) at values of 25, 50, 75, and 100 vol.%. Experimental results showed that the ALWA partially replacing FA in range of 25–100 vol.% significantly decreased both the unit weight and dried density of the fresh and hardened IC-SSC mortars at average values of 13.9% and 20.0%, when compared with the reference SSC mortar, respectively. The ALWA increment continuously reduced the compressive strengths of the hardened IC-SSC mortars. But, at 28 days of curing, the hardened IC-SSC mortar containing the ALWA amount partially replacing FA up to 50 vol.% showed compressive strength reaching 89.3%, and comparable or slightly lower drying shrinkage in comparison with the reference SSC mortar without the IC agent.

Bacterial biofilms are agglomeration of bacterial cells, stuck to the material surfaces of material in wet environments and formed by a self-produced matrix. The formation of bacterial biofilms is a great risk for the milk processing industry, as the survival of many bacterial species in cow milk may lead to many problems such as microbial spoilage, deterioration in quality, and consumer health risks. This study aimed to identify biofilm formation bacteria from cow milk. The experiment included isolation; biofilm forming assay in 96-well microtiter plates and the identification of microbial isolates using classical and molecular biological methods. A total of 14 bacterial isolates from 10 cow milk samples were evaluated for their biofilm formatting ability. Among them, four isolates were identified as moderate and strong biofilm producers. These four isolates belong to the genera Serratia and Aeromonas. Out of the 4 isolates, Serratia marcescens VL41 was classed as a strong biofilm producer while Aeromonas veronii ST15, Aeromonas sp. ST17, Serratia marcescens VL13 were classed as moderate biofilm producers respectively. The findings of this study suggest that it is necessary to discover the contamination causes and prevention of genera Serratia, and Aeromonas into cow milk.

Authors: Syoufian Akhmad , Kurniawan Rian
Published: June 2023

Composites of manganese and nitrogen-codoped zirconium titanate (Mn,N-codoped ZrTiO4) had been synthesized by the sol-gel method as a visible-light responsive photocatalyst for the photodegradation of methylene blue (MB). Synthesis was conducted at 25 °C using titanium(IV) isopropoxide, zirconium oxide, urea, and manganese(II) chloride. Mn,N-codoped ZrTiO4 containing fixed 10% nitrogen dopant (wN/wTi) with various Mn dopant contents (2, 4, 6, 8, and 10% wMn/wTi) and calcination temperatures (500, 700, and 900 °C) had been investigated. All of the Mn,N-codoped ZrTiO4 exhibit a band gap within the visible range (2.51 to 2.74 eV). Photodegradation of MB was performed under visible light illumination for 120 min. The highest activity was achieved up to 7.7 µg L−1 min−1, which was obtained from Mn,N-codoped ZrTiO4 calcined at 500 °C containing 6% Mn and 10% N dopants.

Published: June 2023

Kanker kulit benign (jinak) dan malignant (ganas) merupakan jenis kanker kulit yang sering dijumpai. Tanda-tanda kanker kulit penting untuk diketahui dengan diagnosis dini agar dapat diberikan penanganan yang tepat, sehingga dapat mengurangi tingkat kematian penderitanya. Citra dermoskopi menjadi salah satu media diagnosis yang telah banyak dikembangkan oleh peneliti. Analisis citra dermoskopi memberikan hasil lebih optimal dalam diagnosis berbasis komputasi dibandingkan deteksi visual. Model yang berhasil diterapkan dalam diagnosis berbasis komputasi tersebut di antaranya deep learning dan transfer learning, tetapi masih diperlukan optimalisasi. Pada penelitian ini, dilakukan klasifikasi citra dermoskopi kanker kulit ke dalam dua kelas (benign dan malignant) dengan memanfaatkan transfer learning. Untuk meningkatkan akurasi penelitian yang telah dilakukan sebelumnya pada dataset publik dari Kaggle dengan jumlah 3.297 citra, penelitian ini menggunakan 2.000 citra. Penelitian ini membandingkan dua pre-trained model, yaitu VGG-16 dan residual network (ResNet)-50 yang digunakan sebagai feature extractor. Selanjutnya dilakukan fine-tuning dengan menambahkan flatten layer, dua dense layer dengan fungsi aktivasi ReLU, dan satu dense layer dengan fungsi aktivasi Softmax untuk melakukan klasifikasi ke dalam dua kelas. Hyper parameter tuning pada optimizer, batch size, learning rate, dan epoch dilakukan untuk mendapatkan kombinasi parameter dengan kinerja terbaik pada masing-masing model. Sebelum dilakukan hyper parameter tuning, model diuji dengan resize citra masukan menggunakan ukuran yang berbeda-beda. Hasil pengujian model menggunakan citra uji pada model VGG-16 memberikan kinerja terbaiknya pada ukuran citra 128 × 128 piksel dengan kombinasi parameter Adam sebagai optimizer, batch size 64, learning rate 0,001, dan epoch 10 dengan nilai akurasi 91% dan loss 0,2712. Model ResNet-50 memberikan akurasi yang lebih baik, yaitu 94%, dan loss 0,2198 dengan parameter optimizer RMSprop, batch size 64, learning rate 0,0001, dan epoch 100. Hasil pengujian ini menunjukkan bahwa metode yang diusulkan memberikan akurasi yang baik dan dapat membantu dermatologi dalam deteksi dini kanker kulit.
