Твердi щiльно-упакованi плiвки напiвпровiдникових нанокристалiв (НК) проявляють специфiчнi оптоелектроннi властивостi, зумовленi сильною квантовою взаємодiєю I гiбридизацiєю орбiталей екситонiв мiж НК. Це вiдкриває шляхи до створення нових штучних свiтлозбираючих комплексiв та фотовольтаїчних структур з просторовим роздiленням електронiв та дiрок. Метою даної роботи було дослiдження колоїдних розчинiв та твердих плiвок НК ZnSe, стабiлiзованих тiоглiцеролом, за допомогою стацiонарних та часороздiльних вимiрiв оптичних спектрiв. Ми виявили, що в розчинах НК переважає релаксацiя та рекомбiнацiя екситонiв через поверхневi та дефектнi стани електронiв та дiрок, в той час як в плiвках домiнуючим каналом релаксацiї екситонiв переважно є квантовий (внутрiшнiй). Причина домiнування останнього зумовлена швидким (субнаносекундним) переносом енергiї екситонного збудження в плiвках вiд менших НК до бiльших, що було встановлено через вимiри спектрiв фотолюмiнесценцiї з роздiленням у часi.

Published: November 2022

Cultural difference is one of the elements that form individuals. It corresponds with attitudes and beliefs that influence human cognition and behavior. As a response, it is essential to study cultural differences to develop an appropriate measurement tool. This study aims to (1) evaluate the psychometric properties of the IPIP-BFM short version scale based on the Bugis-Makassar cultural setting and also (2) compare with Javanese cultural background results. A total of 430 students participated (78% women and 22% men). We observed that the Item-total correlation ranged from 0.51 to 0.74, with reliability coefficient: intellectual (0.85); consciousness (0.85); extraversion (0.85); agreeableness (0.79); and neuroticism (0.89). The Kaiser Meyer-Olkin was 0.87, and the Bartlett Test of Sphericity was 5191,3 (p < 0.01). All the items had a factor loading >0.60; variance explained 63,1 (63%) and clear factorial structures. The short version scale had good psychometric properties. Meanwhile, the items comparison of the two measurement tools from both cultural backgrounds reveals that two-item were the same in factors: intellectual, extraversion, and emotional, while four items were in consciousness. However, on the agreeableness factor, all items were the same. It shows that cultural variations indeed affect an individual's perception of an item.
Rasch Analysis of The Indonesian Version of Individual Work Performance Questionnaire (IWPQ)
Authors: Dwiliesanti Weepy Grace , Yudiarso Ananta
Published: November 2022

The Individual Work Performance Questionnaire was developed by Koopmans et al. (2013). This questionnaire was based on the construct of individual work performance which consists of task performance, contextual performance, and counterproductive work behavior. Widyastuti & Hidayat (2018) adapted the IWPQ into Bahasa Indonesia. The mentioned research used the classical test theory (CTT) approach to validate the instrument. Therefore, the findings were only applicable to the study’s sample, as validity and reliability could not be legitimately generalized to other study settings. In comparison, the development of the original IWPQ used Rasch analysis to examine its measurement properties. Rasch analysis is a modern psychometric approach based on item response theory (IRT), which has several advantages over the CTT. This study aimed to validate the psychometric properties of the Indonesian Version of IWPQ using the Rasch model. The psychometric properties discussed in this study include instrument reliability, person and item reliability, unidimensionality, rating scale functioning, and bias detection (Differential Item Functioning). The 213 participants in this research survey were Indonesian citizens aged 18-46 years old (mean = 30.64, SD = 8.55) and were actively working for at least three months at their current job. The result showed that the assumption of the unidimensionality of each sub-scale of IWPQ was fulfilled. The 5-Likert rating scales of this instrument had adequate functionality. The person reliability for all sub-scales ranged from .58 - .80. Meanwhile, the item reliability ranged from .90 - .97. The separations were considered high with a value ranging from 3.04 – 5.77. All items in this instrument functioned well to measure individual work performance except for one item in sub-scale Contextual Performance. This specific item should be revised to achieve a more accurate measurement of the construct. There was one item that was considered biased toward gender in sub-scale Contextual Performance. Also, there was one item that was considered biased toward tenure in sub-scale Counterproductive Work Behavior. These findings had implications for using the Indonesian Version of IWPQ to assess employees’ individual work performance and recommendations for future research.
Principal Component Analysis and Exploratory Factor Analysis of the Mechanical Waves Conceptual Survey
Authors: Santoso Purwoko Haryadi , Istiyono Edi , Haryanto Haryanto
Published: November 2022

Mechanical waves conceptual survey (MWCS) is a measurement tool established by the physics education research (PER) community to evaluate conceptual physics understanding of mechanical waves. A validation study is still needed to figure out the factor structure of MWCS using two data reduction techniques, namely exploratory factor analysis (EFA) and principal component analysis (PCA). The MWCS dataset in this paper was gathered from physics students (n = 419) from nineteen Ugandan secondary schools. The findings of this research suggested the single factor of the MWCS construct that has emerged from the dataset explored in this study. Several issues involved in the calculation of inter-item correlation within the dataset are suspected as the leading cause of the missing component solution or stable loading in the data. Moreover, there might be other issues that leave open space for future exploration. The findings reported in this paper could be the subject of further discussion in evaluating the validity of the MWCS as a research-based assessment (RBA) to measure students' conceptual understanding of wave mechanics within PER studies.

Authors: Pearson Jeffrey , Schlierf Thomas , Zhang Kathy , Hodrick Jeffrey
Published: November 2022

Keywords Total Knee Arthroplasty, robotic-assisted, opioid use
Background With the rise of robotic arm-assisted total knee arthroplasty (TKA) cases, there is a need to determine if there are clinical benefits associated with this technology. The purpose of this study was to further evaluate if robotic-assisted TKAs result in improved inpatient post-operative outcomes compared to conventional TKAs.
Materials and Methods After IRB approval, a retrospective chart review of 100 robotic-assisted primary TKAs and 100 matched controls undergoing conventional TKA was performed. Patients underwent primary TKA from 2016 to 2018 with minimum 6-month postoperative follow-up by a single fellowship-trained arthroplasty surgeon at a high-volume joint center. Exclusion criteria included <6 month postoperative follow-up, incomplete chart information, inflammatory arthritis, and BMI >40. Demographics and post-operative outcomes, including length of stay (LOS), opioid consumption, duration of opioid use, and discharge status, were recorded.
Results There were no significant differences in pre-operative demographics between the two groups. A decrease in LOS (1.58 vs. 2.18 days, p < 0.001) and morphine equivalents (73.52 vs. 102.50, p = 0.017) was reported for the robotic TKA group compared to the control group. The robotic group also reported fewer patients at six weeks postoperatively requiring opioids compared to the control group (37 vs. 61, p = 0.001). Average KOOS Jr at 6-months postoperatively was 81.73 for the control group and 78.22 in the robotic group (p = 0.039).
Conclusion Robotic-assisted TKA patients experienced significantly decreased LOS, morphine equivalents, and opioid usage at 6-week postoperatively, indicating that there are early clinical benefits of robotic-assisted TKA. No significant differences between the robotic and control groups were reported in pre-operative KOOS Jr. Although average 6-month postoperative KOOS Jr was slightly higher for the control group, the difference was clinically insignificant. Our average KOOS Jr for both cohorts was higher than the national 1-year postoperative average, 76.8.

Published: November 2022

Abstract Recommendation systems are an important feature in the proposed virtual life, where users are often stuck with choices most of the time and need help to be able to find what they are looking for. In this work, contentbased techniques have been employed in the proposed recommender system in two ways, a deep review for content and features contents such as (cast, crew, keywords, and genres) has been conducted. A preprocessing stage using TF-IDF and CountVectorizer methods have been employed efficiently to prepare the dataset for any similarity measurements. Cosine similarity algorithm has been employed as well with and without sigmoid and linear kernals. The achieved result proves that similarities between movies using TF-IDF with - Cosine similarity (sigmoid kernel) overcomes the TF-IDF with - Cosine similarity (linear_kernel) and Cosine similarity with CountVectorizer in collaborative filtering. The accuracy values of different machine learning models are validated with K-fold Cross Validator techniques. The performance evaluation has been measured using ROOT Mean Square Error and Mean Absolute Error. Five Machine learning algorithms (NormalPredictor, SVD, KNNBasic (with k=20 and K=10), KNNBasic (with sim_options), and NMF (in several rating scales)). Accuracies are finally been validated with 3 folds from each validator. The best achieved RMSE and MAE scores are using SVD (RMSE = 90%) and (MAE = 69%), followed by KNNBasic (with sim_options, K= 20), NMF, KNNBasic (K=20), KNNBasic (K=10), ending with KNNBasic(sim_options, K= 10).

Hybrid deep learning – picture fuzzy set model for monitoring human behaviour in forest protection
Authors: Van Pham Hai
Published: November 2022

In conventional monitoring forest protection, detection methods use optical sensors or RGB cameras combine features including smokes, fires and human-destroyed forests at national forests. This paper has presented a new approach using Deep learning integrated with Picture Fuzzy Set for the surveillance monitoring system to be activated to confirm human behaviour in real-time in forest protection. Picture Fuzzy Graph (PFG) are applied to solve many complex problems in the real-world problems. The paper has presented a novel approach using deep learning with knowledge graphs to find a human profile including the detection of humans in large data. In the proposed model, digital human profiles are collected from conventional databases combination with social networks in real-time, and a knowledge graph is created to represent complex-relational user attributes of human profile in large datasets. PFG is applied to quantify the degree centrality of nodes. To confirm the proposed model, the proposed model has been tested with data sets through case studies of a forest. Experimental results show that the proposed model has been validated on real world datasets to demonstrate this method’s effectiveness.
Afetividade negativa e intenção de abandono entre estudantes de Ciências Contábeis durante a pandemia da Covid-19
Authors: Souza Maria Gerlúcia Bezerra de , Aquino Cíntia Vanessa Monteiro Germano , Silva Clayton Robson Moreira da
Published: November 2022

A pandemia da Covid-19 trouxe efeitos negativos para a saúde mental da população. Sintomas de depressão, ansiedade e estresse, aqui denominados de afetividade negativa, foram potencializados no período pandêmico, o que pode ter gerado um impacto na intenção dos estudantes de abandonar seus cursos superiores, tendo em vista o cenário de adversidades. Nesse contexto, este estudo teve como objetivo verificar a influência da afetividade negativa na intenção de abandono entre estudantes de ciências contábeis durante a pandemia da Covid-19. Para tanto, realizou-se uma pesquisa do tipo survey com 194 estudantes do curso de ciências contábeis de uma universidade pública. Para a análise de dados, foram utilizadas técnicas de análise descritiva, análise fatorial confirmatória e modelagem de equações estruturais. O modelo estrutural foi desenvolvido à luz da Teoria do Comportamento Planejado, que permitiu verificar a influência das atitudes, norma subjetiva e controle comportamental percebido sobre a intenção de abandono. Ainda, o modelo amplia o escopo da teoria ao integrar a variável afetividade negativa, formada por elementos relacionados a sintomas de depressão, ansiedade e estresse. Os resultados evidenciaram que a intenção de abandono é influenciada pela atitude em relação ao abandono e pela afetividade negativa, de modo que uma atitude desfavorável ao comportamento reduz a intenção de abandono, enquanto uma maior incidência da afetividade negativa (i.e., sintomas de depressão, ansiedade e estresse) potencializa a intenção do estudante deixar o curso. Por outro lado, a norma subjetiva e o controle comportamental percebido não apresentaram influência sobre a intenção de abandono, divergindo do que é proposto pela Teoria do Comportamento Planejado. Do ponto de vista gerencial, os achados da pesquisa contribuem para que gestores universitários elaborem estratégias com foco na retenção de estudantes e na promoção e preservação da saúde mental no ambiente universitário, tendo em vista que, ao melhorar as condições psicológicas dos estudantes, os níveis de abandono tendem a reduzir. Além disso, do ponto de vista social, a pesquisa contribui ao promover o debate sobre a importância de um ambiente acadêmico saudável e favorável ao bem-estar psicológico dos estudantes.
Sentience, Sentences, and Sentiment: Sensing Deep-Ocean Sediment through Artistic Practice
Authors: Rawlings Angela
Published: November 2022

At this moment of climate crisis, deep-ocean carbon sequestration has been proposed as a strategy to curtail greenhouse gas emissions. The video article Sentience, Sentences, & Sentiment: Sensing Deep-Ocean Sediment through Artistic Practice explores ecological attunement and the role of language in perceiving the more-than-human—specifically the deep-ocean ecosystems facing potential carbon sequestration, ocean acidification, global heating, and eutrophication. The article unfolds an artist’s account of process for kór (core). An interdisciplinary artwork and slow installation, kór (core) features a deep-ocean sediment core extracted between Greenland and Iceland at a depth of 1,682m during a June 2021 science research cruise. In Icelandic, kór means choir or chorus; it is pronounced similarly to the English-language core. The article features video aboard the research vessel, the acquisition of the core, conceptual documentation of the resulting artwork kór (core), participant interviews, soundscape recordings, and an aria composed through the installation.kór (core) performs a slow installation as a point of activation, where community members contribute to, think with, and create in the context of considering the sentient being-ness of sediment. On a chalkboard, community members mark their reactions to and within the presence of deep-ocean water and sediment. This article shows multilingual sense-making (English, Icelandic, Polish, Danish, Spanish) and the sensorial materialities of bodies (human, cetacean, water, etc.) in the contexts of marine-terrestrial biospheres impacted by the climate crisis. The video aims to elucidate a creative investigation into an expanded notion of relations—crucial for collaborative survivorship in our multi-entity worldings.

Published: November 2022

An eutectic alloy in the LaB6‒VB2 system was obtained by the cold crucible method. The ratio of components in the initial powder mixture was 40:60 mol. %. In the structure of the alloy, two-phase eutectic regions are observed, which are a LaB6 matrix filled with cylindrical VB2 fibers up to 2 μm in diameter or extended VB2 crystals with a complex cross-section and an equivalent diameter of up to 10‒15 μm. The Vickers hardness and the fracturetoughness were determined, and the relationship between these characteristics and the load on the indenter, the direction of load application, and the type of eutectic structure was established. The maximum value of crack resistance (8,6 MPa·m1/2) and high hardness (20,0 GPa) were recorded for an alloy with a rod eutectic structure when a 2 N indenter load was applied parallel to the crystallographic axis c VB2. The greatest hardening effect both at a load of 2 N and 30 N, expressed in a combination of high hardness (20,5 GPa at 2 N and 20,0 GPa at 30 N) and crack resistance (6,5 MPa·m1/2 at 2 N and 4,9 MPa·m1/2 at 30 N) was demonstrated by an alloy with a coarse conglomerate eutectic structure.

Published: November 2022

The use of slag from the smelting of carbon-free ferrochrome with increased contents of refractory oxides (Al2O357,8 wt. %, CaO 14,9 wt. %, MgO 12,7 wt. %, and Cr2O35,6 wt. %) in the production of acid-resistant materials based on non-enriched kaolin clay, it allows to obtain acid-resistant products with high physical, mechanical and chemical parameters in the range of firing temperatures of 1250‒1300 oC. Тhe introduction of slag from the smelting of carbon-free ferrochrome into the compositions of ceramic masses contributes to the formation of highly refractory minerals (corundum, chromium oxide, bonite, mayenite, magnesia overcoat) and an increase in the content of mullite, and also reduces open porosity and thereby strengthens the product.

Solid solutions in the In2O3‒ZrO2 system are formed on the basis of a disordered phase of the C1 type of indium oxide. It was found that in the temperature range 1450‒1600 °C in air. limited solid solutions of the following type are formed in the system: subtraction-substitution, substitution, subtraction-substitution-introduction. The sizes of indium and zirconium cations, the number of defects determine the type of solid solution in a system based on In2O3 with additions of ZrO2. Experimentally, the formation of a mixture of two solid solutions of type C‒Ia3-based on oxides In2O3 and Zr2O3, after annealing the samples at 1600 °C, and were determined elementary cells of these solutions. The energies of formation of solid solutions of subtraction-substitution, substitution, subtractionsubstitution-introduction in the system based on In2O3 are calculated. It was found that the electrical resistance, concentration and mobility of charge carriers in samples based on In2O3 with additions of ZrO2 depends on the type of solid solution and does not depend on the valence of the soluble additive ZrO2. The types of conductivity of free charge carriers in solid solutions are determined and their energies are calculated. Ill. 4. Ref. 20.

Çalışmamızın temelinde yer alan Kırım Bahçesaray ve Romanya Köstence Ağızları farklı coğrafyada bulunsalar da Kırım Türkçesi Ağzını temsil etmektedirler. Hem Kıpçak, hem Oğuz Türkçesinin dil özelliklerini bulunduran Bahçesaray Ağzı, günümüz Kırım Türkçesi edebi dilinin temelini oluşturmaktadır. Köstence Ağzının dil özellikleri daha çok Kıpçak Türkçesine ait unsurlar içermektedir. 1783’te Kırım’ın işgali ile başlayan göç hareketleri Kırım Türklerinin Romanya bölgesine göç etmelerine neden olmuştur. Kırım Türkleri’nin Romanya’nın Dobruca vilayetine yerleşmesi ile Köstence Ağzı oluşturulmuştur. Bugün Kırım Türkçesi, UNESCO tarafından düzenlenen Tehlike Altındaki Diller Atlası’nda “ciddi tehlike altında” olan diller kategorisinde yer almaktadır. Bahçesaray ve Köstence Ağızlarında geniş olarak kullanılan +LIK ekinin fonksiyonları günümüzdeki dilcilikte tartışmalı görüşlere yol açmaktadır. Dilciler tarafından sıfatlama eklerinin yapım ekleriyle karıştırılarak yapım eklerinin kelimenin anlamını değiştirmek dışında türünü de değiştirdiği ifade edilmektedir. Sonuç olarak bu da dil bilgisi bakımından sıkıntı yaratmaktadır. Hazırladığımız çalışmada +LIK ekinin fonksiyonları Köstence ve Bahçesaray Ağızlarına ait derleme metinlerin tanıklığıyla tespit edilmeye çalışılmıştır. İnceleme yaptığımız ağızlarda +LIK ekinin kullanımının fazla olduğunu, ayrıca kelime yapımında ve tamlama oluşumunda önemli bir yer aldığını belirtmek isteriz. Söz konusu ekin üstlendiği işlevleri dikkate alınarak önce üst fonksiyonları, sonra bu üst fonksiyonların alt fonksiyonları incelenerek tanıtılacaktır. Ele aldığımız ekin konuşma sırasında meydana gelen ses hadiselerine dayalı bir sıra alt morfemleri tespit edilerek çalışmaya dahil edilmiştir.
KÜRESELLEŞME, ORTA EKONOMİK SINIFLAR VE MİLLİ-DEVLETLER

Küreselleşme son yıllarda üzerinden en çok konuşulan olgulardan bir tanesidir. Bazıları bu süreci “başımıza gelen tüm kötülüklerin nedeni” olarak görürken birileri de küreselleşmeyi “insanlığın ulaşmak istediği son ve en yüksek hedef” olarak değerlendirmektedir. Her iki görüşe de mesafeli yaklaşanlar bile küreselleşme sürecinin engellenemez olduğunu kabul etmektedirler. Biz biliyoruz ki küreselleşme, büyük sermaye sahiplerinin başlattığı ve yönettiği bir olgudur. Küresel sermayeyi ellerinde tutan zenginler; tarihte imparatorlukları ve onu yöneten soylular sınıfını ortadan kaldırmak için milli-devletleri adeta kendi elleri ile kurmuşlardır. Bu gelişmenin ardından dünyada beliren komünizm tehlikesine karşı milli-devletin yönetimini aşırı milliyetçilerin ellerine bırakmışlardır. İkinci düşmanlarından da kurtulan küresel sermaye dünyada var olan sosyalist devletlerin yıkılmasını beklemişlerdir. 21. Asırda sosyalist bloğun çökmesi ve Çin Halk Cumhuriyeti’nin liberal politikalar izlemeye başlaması ile dünyada hâkimiyetlerinin önünde tek güç olarak milli-devletler kalmıştır. Zaten son yıllarda küresel sermaye sahipleri ile milli-devlet ve onun üst düzey yöneticileri arsında bir güç mücadelesi olduğu gözlerden kaçmıyor. Küresel sermayeyi ellerinde bulunduranlar dünya hâkimiyetlerinin önündeki son engel olarak gördükleri milli-devlet ve onun kudretli yöneticilerini itibarsızlaştırma çabası içine girmişlerdir. Dünya hâkimiyetlerinin önündeki son engeli ortadan kaldırmak isteyen küresel sermaye milli-devleti ayakta tutan orta ekonomik sınıfları güçsüzleştirme yönünde ekonomik müdahaleleri yapmaktadır. Küresel sermayenin amacı orta ekonomik sınıfın desteğinden yoksun bırakarak milli-devleti etkisiz kılmaktadır.
21. YY. YAPI PRATİĞİNDE TUĞLANIN BİÇİMSEL VE İŞLEVSEL DÖNÜŞÜMLERİ

Tuğla yapı hafızasını taşıyan, neredeyse her dönemde faklı biçimlerde ve üretim teknikleriyle mimaride kullanılan en eski malzemelerden biridir. İnsanın kendisini dış çevreden ayıran bir boşluk yaratma istenciyle ortaya çıkan ve mekân yaratma arayışlarının paralelinde gelişen tuğla, başlangıçta taş, kırmızı çamur, kerpiç gibi yerel malzemeler kullanılarak üretilmiştir. Bu süreçte tuğla, dış ve iç mekân arasında ki sınırları belirlerken, yapının ana taşıyıcı unsuru olarak işlev kazanmıştır. Yapı endüstrisinde gerçekleşen gelişmeler; beton ve demir gibi yapı elamanlarının mimaride kullanılmaya başlanması, tuğlanın temel işlevi olan, “yapının taşıyıcı unsuru” niteliğindeki dönüşümlere kaynak oluştururken, tuğla, yapıya dekoratif bir takım özellikler katmak ve yüzeyi kaplamak için kullanılan bir yapı elamanına dönüşmüştür. Cephe ve yüzey mimarisi kavramlarının gelişimi, mimari mekânlar için yeni yüzey ve biçim önerileri geliştirilmesini tetiklerken, daha organik bir yapı pratiğinin yaratılmasına sebep olmuştur. Bu süreçte ekstrüzyon araçlarının mimaride kullanımı, tuğlanın boşluksuz olarak üretilmesine olanak sağlarken, tuğlanın yüzey ile kurduğu dekoratif ilişkilerin gelişmesini de zorunlu hale getirmiştir. Otomasyon sistemlerinin ve katmanlı üretim teknolojilerinin yapı endüstrisine entegrasyonu ve daha sürdürülebilir bir yapı pratiği arayışı, tuğlanın taşıyıcı bir yapı elamanı olmasının ötesinde, yapı pratiğinde bir tasarım unsuru, yapıya yeni birtakım özellikler kazandıran bir araç olarak kullanılmasına olanak sağlamıştır. Araştırmada, günümüzde mimari pratiği içinde tuğlanın kullanım biçimindeki dönüşümler örnekler üzerinden incelenerek değerlendirilecektir.
The Intergenerational Representation of Old Age in the Transition to Frailty: An Empirical Analysis in Italy
Authors: Bramanti Donatella
Published: November 2022

The results presented here are part of the outcome of a research project titled Redesign—Frail Elderly, Intergenerational Solidarity and Age-Friendly Communities (https://redesignanziani.com) funded by Fondazione Cariplo and coordinated by the Università Cattolica del Sacro Cuore in Milan, in collaboration with Università degli studi di Verona and Università degli studi del Molise (2019–2022). The research aims to co-acquire knowledge of the transition to old age in vulnerable situations, to develop and implement new community networks of care, and thus promote health and well-being, active ageing, and intergenerational solidarity in eight Italian municipalities. The analysis of the dyadic interviews, conducted with the NVivo software, will provide the image of ageing and old age emerging from an intergenerational dialogue. By analysing results, it will therefore be possible to identify some specific types of representation of old age in relation to the dyad, the stressful events that occurred to the interviewees and in relation to the ways of living the transition. The representation of old age seems closely connected with the quality and intensity of relationships, the environment of associative and local life that the interviewees relate to, and the stressful events that have recently occurred to them.

Dental caries occurs due to the demineralization of tooth structure caused by microorganisms in colonies called biofilms. One of the microorganisms involved in dental caries is Streptococcus mutans. Oral mouthwash, in addition to mechanical cleaning, is known to prevent the growth of oral microorganisms. Mangosteen is known as an anti-cancer ingredient with high anti-bacterial properties. This study aims to identify the effectiveness of mangosteen skin extract (Garcinia mangostana L.) in decreasing Streptococcus mutans biofilm. The study is experimental research with a post-test control group design. The research sample was divided into five groups; 3 treatment groups and 2 control groups. The biofilm thickness test was carried out with OD (Optical density) with a wavelength of about 620 nm using an ELISA reader. Kruskal Wallis analysis was employed as a non-parametric statistical test analysis. Statistical Kruskal Wallis indicated significant differences in the thickness of 5 test groups of Streptococcus mutans. The lowest average yield of biofilm thickness was in the α-mangosteen group at 12.5 g/ml. Conclusion: α-mangosteen in mangosteen skin extract effectively reduced the thickness of Streptococcus mutans biofilm.
The Difference of Microleakage Between One-Bulkfill Resin Composite and Conventional Resin Composite
Authors: Dwi Atmaja Widyapramana
Published: November 2022

Resin composites are the most commonly used restorative materials and are constantly evolving due to their shortcomings which can affect the restoration results in polymerization shrinkage, leading to the formation of microleakage. Although incremental techniques have been found, this technique has drawbacks regarding the time required and the possibility of contamination. The invention of bulk fill resin composite can solve this problem. Manufacturers of One-Bulkfill (3M ESPE) claim that this material has less polymerization shrinkage than conventional resin composites, which is expected to have less chance of microleakage. This study aims to determine the difference in microleakage between one-bulkfill resin composites and conventional resin composites. 20 extracted premolars without caries and anomalies were utilized as research samples. These teeth were then prepared to form a class 1 cavity, then divided into two groups, namely; (1) One-Bulkfill (3M ESPE) and (2) Z350 XT (3M ESPE). These two samples were immersed in 1% Methylene Blue solution and observed using a Camera with a Macro Lens. Data were analyzed using an independent sample t-test. The results demonstrated a significant difference in microleakage between the two groups (p = 0.014, p0.05). The mean value of microleakage in One-Bukfill composite resin restorations was 0.022, while Z350 XT composite resin restorations had 0.038. It can be concluded that the One-Bulkfill composite resin restoration had a smaller microleakage value than the conventional composite resin restoration (Z350 XT).

Background: Newborn respiratory complication is one of the most prevalent and life-threatening disorders. The clinical indications of early newborn respiratory distress with consistent radiologic features. The Doppler examination of the primary pulmonary artery in the foetus has been proven to be beneficial. The foetal pulmonary artery At/Et ratio is linked to foetal gestational age and amniotic fluid foetal lung maturity (FLM) tests. The aim of the study was to assess the accuracy of foetal main pulmonary artery (MPA) Doppler indices in prediction of the development of neonatal respiratory distress syndrome (RDS) in diabetic mothers.Methods: This was a prospective observational study carried out on 100 cases of diabetic mothers in obstetrics and gynecology department, Tanta University during one year from the approval of the university counsel. The physician evaluated the foetal heart in a methodical manner after a regular ultrasound assessment that included foetal biometry, anomaly scan, measured foetal weight, and amniotic fluid index. Classic chest radiological features include reticulogranular patterns, air bronchogram and ground glass look, as well as the need for surfactant.Results: PI and RI were significantly higher in newborns with RDS than those without RDS (p=0.025 and 0.036 respectively) PSV and At/Et ratio were significantly reduced in neonates with RDS compared with RDS free ones (p=0.004 and <0.001 respectively). RI was significantly higher in neonates with RDS than those without RDS (P = 0.048) PSV and At/Et ratio were significantly reduced in newborns with RDS compared to RDS free ones (p=0.008 and <0.001 respectively). The ROC curve displayed that the cut off value of ≤0.25 for At/Et ratio was associated with a sensitivity of 76.92%, a specificity of 100.0%, a PPV of 100.0% and a NPV of 96.7% for prediction of neonatal RDS with AUC of 0.925 and p≤0.001.Conclusions: development of neonatal RDS in foetus of diabetic mothers with a cut off value of ≤0.25, a sensitivity of 76.92%, a specificity of 100.0%, a PPV of 100.0%, a NPV of 96.7% and AUC of 0.925 The usage of corticosteroids improved the Doppler indices of main pulmonary artery and is accompanied by less morbimortality related to RDS.
