Literatürde Alzaatreh ve diğerleri [10] çalışmalarında genelleştirilmiş Weibull-X dağılım ailesini önermişlerdir. Önerilen dağılımdan yararlanarak, bu çalışmada yeni bir Weibull-Lindley (NWL) dağılımı geliştirilmiştir. Olasılık yoğunluk, dağılım, yaşam, hazard ve kantil fonksiyonları, mod, medyan, Shannon entropisi, çarpıklık ve basıklık katsayıları, sıralı istatistikleri gibi birçok matematiksel özellik de elde edilmiştir. Maksimum olabilirlik yöntemine göre parametre tahmini yapılmıştır. Uygulama kısmında gerçek veri setlerini kullanılmış ve elde edilen sonuçlara göre, önerilen NWL dağılımımız Akash, Lindley, New Weibull-F, iki parametreli Lindley (TPL) ve Weibull-Lindley (WL) dağılımları ile karşılaştırıldığında daha üstün olduğu sonucuna ulaşılmıştır.

In this study, a decision making mechanism for personnel selection was created by using the intuitionistic fuzzy based TOPSIS method, which is one of the multi-criteria decision making methods. According to the criteria determined by the decision makers, each candidate was evaluated individually by the decision makers and the most suitable personnel were selected. During the evaluation, the decision makers expressed their views through linguistic terms. Thanks to the intuitionistic fuzzy sets, situations where decision makers are undecided have become meaningful. This decision making mechanism prepared for personnel selection may be utilized by any company that will select personnel and the criteria may be changed in accordance with the purpose of the company. This study, which will attract the attention of many researchers in the field of decision making, will shed light on demanded application areas.
本文采用多准则决策方法之一的基于直觉模糊的TOPSIS方法,构建了一种人员选择决策机制。根据决策者确定的标准,由决策者对每个候选人进行单独评估,选择最合适的人员。在评价过程中,决策者通过语言术语表达了他们的观点。由于直觉模糊集,决策者犹豫不决的情况变得有意义。这一为人员选择准备的决策机制可以被任何公司使用,并且可以根据公司的目的改变标准。这一研究将会引起决策领域许多研究者的关注,并将会揭示出所需的应用领域。

Among skeletal deformities, Class III is the one that best time for the treatment is the pre-adolescent growth period. Diagnosis and treatment in this period continue to be a complex orthodontic problem. Class III malocclusion is especially difficult to treat with braces frequently requiring surgical intervention after pubertal growth spurt. In addition, delayed recognition of the problem will yield to significant functional, aesthetic and psychological concerns. In this study, we proposed a comparative analysis of three predictive models to predict Class III malocclusion: deep learning algorithm, machine learning algorithm and a rule-based algorithm. For this analysis, we collected a novel profile image data set along with their formal diagnosis from 435 orthodontics patients. The most successful method among the three was the machine learning method with an accuracy of %76.
在骨骼畸形中,第三类畸形的最佳治疗时间是青春期前的生长发育时期。这一时期的诊断和治疗仍然是一个复杂的正畸问题。第三类错牙合尤其难以治疗,往往需要手术干预后,青春期生长突增。此外,延迟认识到这个问题将产生重大的功能,美学和心理问题。在本研究中,我们提出了三种预测模型来预测III类错:深度学习算法、机器学习算法和基于规则的算法。为了进行这项分析,我们从435名正畸患者中收集了一组新的侧面图像数据集以及他们的正式诊断。三种方法中最成功的是机器学习方法,准确率为%76。

In recent years, studies have focused on the development of fire retardant products that are produced without the use of flame retardants with toxic effects and do not have harmful effects on humans and the environment. In this work, it has been compared the flame retardant properties of some biodegradable fibers obtained from different sources. It is important to investigate the performance of textile surfaces obtained from renewable fibers for flame retardant products and to improve their usage possibilities. The fire retardancy properties of knitted fabrics containing PLA, cotton, lyocell, and chitosan fibers were studied by analyzing the LOI values and burning behaviors. Single jersey knitted fabrics composed of 100% PLA, 100% Lyocell, 95% PLA 5% Chitosan, 95% Cotton 5% Chitosan, 95% Lyocell 5%Chitosan, 80%PLA 15%Cotton 5%Chitosan, 80%PLA 15%Lyocell 5%Chitosan were produced. The flame speed of each material was determined and differences in the flammability behaviors of the fabrics were identified. The lowest flammability occurred for the fabric 95% PLA and 5% Chitosan. The highest flammability was for 100% Lyocell knitted fabric. Knitted textile structures were evaluated for their flammability using the standard fire test ISO 6941. Also, the limiting oxygen index (LOI) of knitted fabrics under ASTM: D2863 was evaluated.
近年来,研究的重点是开发不使用具有毒性作用的阻燃剂,对人体和环境不产生有害影响的阻燃产品。本文比较了几种不同来源的可生物降解纤维的阻燃性能。研究由可再生纤维制成的纺织品表面的阻燃性能并提高其使用的可能性是很重要的。通过分析LOI值和燃烧行为,研究了聚乳酸(PLA)、棉纤维、莱塞纤维和壳聚糖纤维针织物的阻燃性能。生产了由100%聚乳酸、100%莱赛尔、95%聚乳酸5%壳聚糖、95%棉5%壳聚糖、95%莱赛尔5%壳聚糖、80%聚乳酸15%棉5%壳聚糖、80%聚乳酸15%莱赛尔5%壳聚糖组成的针织单品针织织物。测定了每种材料的燃烧速度,确定了织物的燃烧性能差异。95%聚乳酸和5%壳聚糖的织物可燃性最低。100% Lyocell针织物的可燃性最高。采用ISO 6941标准防火测试对针织织物结构的可燃性进行了评估。在ASTM: D2863标准下,对针织物的极限氧指数(LOI)进行了评价。

Mushrooms are a popular food because they are an important source of essential amino acids, proteins and dietary fibers, but they have a great capacity to accumulate metals from substrate. Due to this reason, the content of 5 trace metals (Fe, Cr, Zn, Pb, Se) of fruit bodies of 21 fungi species originally found in Azdavay, Kastamonu Region, Turkey were analyzed by atomic absorption spectroscopy. The contents of investigated trace metals in mushroom samples were found to be in the range of 4.6–3478.7 mg kg-1 for Fe, 5.1–19.9 mg kg-1 for Cr, 10.4–138.6 mg kg-1 for Zn, 5.8–28.0 mg kg-1 for Pb and 0.65–1.47 mg kg-1 for Se.The relative standard deviations (R.S.D.) were found below 10%. The accuracy of procedure was confirmed by CRMs (BCR 191 Brown bread, ERM-BD 151 Skimmed milk powder)

A new Multi-Party Private Set Intersection Protocol based on OPRFs 一种新的基于OPRFs的多方私有集交叉协议

In many crucial real-world applications, parties must jointly perform some secure multi-party computation (MPC) while keeping their inputs hidden from other parties. Private Set Intersection (PSI), the specific area of Multi-Party Computation, let the parties learn the intersection of their private data sets without sharing their secret data with others. For instance, a smartphone user downloads a messaging application, naturally, he wants to discover who are the other contacts that are using the same application. The naive and insecure solution is to send all contacts to the server to discover them. However, the user does not want to share his contacts with the application for privacy issues. To handle this, in recent years, companies and organizations start to use PSI to enhance privacy and security with a little cost of communication and computation. In this paper, we introduce a novel method to compute Private Set Intersection with multi parties where there are at least three or more parties participate in the protocol. By employing Zero Secret-Sharing and Oblivious Pseudo-Random Functions, parties securely calculate the intersection with computational and communication complexities which are both linear in the number of parties.
在许多关键的现实世界应用程序中,各方必须联合执行一些安全的多方计算(MPC),同时对其他各方隐藏其输入。私有集交集(Private Set Intersection, PSI)是多方计算的一个特定领域,它允许各方在不与他人共享其秘密数据的情况下了解其私有数据集的交集。例如,智能手机用户下载了一个消息传递应用程序,很自然地,他想知道谁是使用同一应用程序的其他联系人。幼稚且不安全的解决方案是将所有联系人发送到服务器以发现他们。但是,出于隐私问题,用户不希望与应用程序共享他的联系人。为了解决这个问题,近年来,公司和组织开始使用PSI来增强隐私和安全性,同时减少通信和计算成本。本文提出了一种计算至少有三个或更多参与方的多参与方私有集交集的新方法。通过使用零秘密共享和遗忘伪随机函数,各方安全地计算出具有计算和通信复杂性的交点,这些交点在各方数量上都是线性的。

The aquaculture of European sea bass and Gilthead sea bream has increased significantly in Turkey, especially as they are exported mostly to the EU countries. The purpose of this study is to calculate inorganic arsenic (iAs) levels through the determination of total arsenic amounts (AsT) in muscle tissues of European sea bass (Dicentrarchus labrax L., 1758) cultured in cages at sea and earthen ponds and wild sea bass caught from the coast of Mugla, Turkey. This study also presents a risk assessment of European sea bass consumption in terms of consumer health. For this aim, muscle tissues of fish were mineralized with microwave digestion and total arsenic concentrations were detected with the method of inductively coupled plasma mass spectroscopy (ICP-MS). It is found that the highest level of mean arsenic is detected in sea bass cultured in earthen ponds (0.38 mg kg-1) and the amount of mean arsenic is measured as 0.26 mg kg-1 in sea bass cultured off-shore and wild sea bass. It is revaled that there is not any negative outcome for human health as a result of risk assessments based on estimated daily intake (EDI), target hazard quotient (THQ), carcinogenic risk (CR) and lifetime cancer risk (TR).
在土耳其,欧洲鲈鱼和金头鲷鱼的水产养殖显著增加,特别是因为它们主要出口到欧盟国家。本研究的目的是通过测定海上和土池网箱养殖的欧洲海鲈鱼(Dicentrarchus labrax L., 1758)和土耳其穆拉海岸捕获的野生海鲈鱼肌肉组织中的总砷含量(AsT)来计算无机砷(iAs)水平。本研究还从消费者健康的角度对欧洲黑鲈消费进行了风险评估。采用微波消解法矿化鱼肌肉组织,电感耦合等离子体质谱(ICP-MS)法测定鱼肌肉组织中总砷浓度。结果显示,土塘养殖的黑鲈平均砷含量最高(0.38 mg kg-1),而近海养殖的黑鲈和野生黑鲈的平均砷含量为0.26 mg kg-1。结果表明,基于估计每日摄入量(EDI)、目标危害商(THQ)、致癌风险(CR)和终生癌症风险(TR)的风险评估对人类健康没有任何负面影响。

Metallic nanoparticles are interesting areas of research due to their unique properties which can be advantageous for producing smart products. Silver nanoparticles (AgNPs) are remarkably used in pharmaceutical industry because of their strong biological activities. The aim of the present study was to investigate the cytotoxicity and wound healing capacity of the biologically prepared silver nanoparticles via green synthesis route. Cytotoxicity of the biogenic AgNPs was determined by MTT (3- [4, 5- dimethyl-2-thiazolyl]-2, 5-diphenyl-2H-tetrazolium-bromide) assay against L929 fibroblast cell line. Wound healing properties of the AgNPs were evaluated using in vitro-scratch wound healing assay using 3T3 fibroblast cell line. Biosynthesized AgNPs inhibited the propagation of fibroblasts at a half maximal inhibitory concentration (IC50) of 23.507 μg/mL after 24 h incubation. In vitro wound healing assay also revealed that the biogenic AgNPs stimulated the 3T3 fibroblasts' cell proliferation. It can be suggested that biologically synthesized AgNPs can be used effectively for biomedical applications such as wound dressing materials.
金属纳米颗粒是一个有趣的研究领域,由于其独特的性质,可以有利于生产智能产品。银纳米颗粒由于具有较强的生物活性,在医药工业中得到了广泛的应用。本研究的目的是通过绿色合成途径研究生物制备的银纳米颗粒的细胞毒性和伤口愈合能力。采用MTT(3-[4,5 -二甲基-2-噻唑基]- 2,5 -二苯基- 2h -溴化四氮唑)法测定生物源性AgNPs对L929成纤维细胞的细胞毒性。采用3T3成纤维细胞系体外划伤创面愈合实验评价AgNPs的创面愈合性能。生物合成AgNPs对成纤维细胞增殖的抑制作用达到最大抑制浓度(IC50)的一半,为23.507 μg/mL。体外创面愈合实验也显示,生物源性AgNPs刺激了3T3成纤维细胞的增殖。这表明,生物合成AgNPs可以有效地用于生物医学应用,如伤口敷料材料。

Silver nanoparticles (AgNPs) are remarkably used in pharmaceutical industry because of their strong biological activities. The aim of the present study was to investigate the cytotoxicity and wound healing capacity of the biologically prepared silver nanoparticles via green synthesis route. Cytotoxicity of the biogenic AgNPs was determined by MTT (3- [4, 5- dimethyl-2-thiazolyl]-2, 5-diphenyl-2H-tetrazolium-bromide) assay against L929 fibroblast cell line. Wound healing properties of the AgNPs were evaluated using in vitro-scratch wound healing assay using 3T3 fibroblast cell line. Biosynthesized AgNPs inhibited the propagation of fibroblasts at a half maximal inhibitory concentration (IC50) of 23.507 μg/mL after 24 h incubation. In vitro wound healing assay also revealed that the biogenic AgNPs stimulated the 3T3 fibroblasts' cell proliferation. It can be suggested that biologically synthesized AgNPs can be used effectively for biomedical applications such as wound dressing materials.","PeriodicalId":149663,"journal":{"name":"Mugla Journal of Science and Technology","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134200327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
