Authors: GEZER Gonca
Published: December 2020

çalışma yaşamını ve istihdam biçimlerin derinden etkilemesi sınıf kavramının yeniden sorgulanmasına neden olmaktadır. Küreselleşme ve neoliberal politikaların bir sonucu olarak güvencesiz çalışmanın giderek yaygınlaşması hem vasıflı hem de vasıfsız işgücü açısından çalışma ve yaşam koşullarını derinden etkilemiştir. Bunun sonucunda sanayi toplumunun proletaryasından farklı olarak güvencesiz çalışanların oluşturduğu, prekarya olarak adlandırılan yeni bir toplumsal sınıfın varlığı tartışılmaya başlanmıştır. Böylece beyaz yakalılar da giderek prekerleşen meslekler içerisinde yerini almaya başlamıştır. Bu çalışmada alışveriş merkezlerinde yönetici pozisyonunda çalışanların sorunları, prekaryanın temel unsurlarından biri olan iş güvencesizliği bağlamında ele alınmıştır. Çalışmada nitel araştırma yöntemi kullanılarak toplam on kişi ile derinlemesine mülakat yapılmıştır. Sonuç olarak AVM çalışanlarının prekarya olarak değerlendirilebileceği tespitine varılmıştır.

Amaç: Çalışmada AVM’lerde çalışan beyaz yakalıların prekarya içerisinde yer alıp almadığının tespit edilmesi amaçlanmıştır.

Yöntem: Çalışmada nitel araştırma yöntemi kullanılmıştır. Bu kapsamda yarı yapılandırılmış soru formu kullanılarak derinlemesine mülakatlar gerçekleştirilmiştir.

Bulgular: Alan araştırmasından elde edilen bulgular AVM çalışanlarının prekaryanın özelliklerini önemli ölçüde taşıdığını göstermektedir. AVM çalışanlarının güvencesiz ve esnek çalışma şartlarıyla karşı karşıya kaldığını; yaşadıkları belirsizlik, risk, kaygı ve umutsuzluk dolayısıyla prekaryanın temel özellikleriyle benzerlik gösterdiğini söylemek mümkündür.

Özgünlük: Prekarya tartışmalarıyla ilgili son yıllarda literatürde teorik ve uygulamalı çalışmalar bulunmasına karşın, AVM çalışanlarıyla ilgili bir alan araştırmasına rastlanılmamıştır. Oysa AVM çalışanlarının çalışma koşulları prekarya tartışmalarıyla önemli ölçüde örtüşmektedir. Bu bağlamda önemli bir istihdam alanı olan AVM’lerde çalışanların prekarya bağlamında incelenmesi çalışmanın özgün yanını oluşturmaktadır.

Published: December 2020

This paper mainly aims at developing an authentication scheme for digital images. The LSB scheme is chosen base for our proposed work. Through literature survey it is found that conventional LSB scheme provides low embedding rat low distortion and is irreversible. Because of its irreversibility, the conventional LSB scheme cannot be used for critic applications where reversibility is mandatory. Through this literature survey, we learnt that this conventional LSB scheme us only one bit in every pixel for embedding. Our proposed scheme presents a modified LSB embedding strategy that satisfies th reversibility and improves the embedding rate by using two bits in every pixel for embedding.
Enhanced Security In Cloud With Multi-Level Intrusion Detection System
Authors: KUZHALISAI M. , GAYATHRI G.
Published: December 2020

Cloud computing is a new type of service which provides large scale computing resource to each customer. Cloud Computing Systems can be easily threatened by various cyber attacks, because most of Cloud computing system needs to contain some Intrusion Detection Systems (IDS) for protecting each Virtual Machine (VM) against threats. In this case, there exists a tradeoff between the security level of the IDS and the system performance. If the IDS provide stronger security service using more rules or patterns, then it needs much more computing resources in proportion to the strength of security. So the amount of resources allocating for customers decreases. Another problem in Cloud Computing is that, huge amount of logs makes system administrators hard to analyse them. In this paper, we propose a method that enables cloud computing system to achieve both effectiveness of using the system resource and strength of the security service without trade-off between them.

Though the benefits are clear, such a service is also relinquishing users ‘physical possession of their outsourced data, which inevitably poses new security risks towards the correctness of the data in cloud. In order to address this new problem and further achieve a secure and dependable cloud storage service, we propose in this paper a new secure framework. In addition to providing traditional computation services, mobile cloud also enhances the operation of traditional ad hoc network by treating mobile devices as service nodes, e.g., sensing services. The mobile services or sensed information, such as location coordinates, health related information, should be processed and stored in a secure fashion to protect user’s privacy in the cloud. In this paper, we present a new mobile cloud data processing framework through trust management and private data isolation. Finally, an implementation pilot for improving teenagers’ driving safety, which is called FocusDrive, is presented to demonstrate the solution.

The study of graph labeling has focused on finding classes of graphs which admits a particular type of labeling. In this paper we consider a particular class of graphs which demonstrates Edge Magic Total Labeling. The class we considered here is a complete bipartite graph Km,n. There are various graph labeling techniques that generalize the idea of a magic square has been proposed earlier. The definition of a magic labeling on a graph with v vertices and e edges is a one to one map taking the vertices and edges onto the integers 1,2,3,………, v+e with the property that the sum of the label on an edge and the labels of its endpoints is constant independent of the choice of edge. We use m x n matrix to construct edge magic total labeling of Km,n.

“Cloud computing” is a term, which involves virtualization, distributed computing, networking, software and Web services. Our Objective is to develop an effective load balancing algorithm using Divisible Load Scheduling Theorem to maximize or minimize different performance parameters (throughput, latency for example) for the clouds of different sizes. Central to these issues lays the establishment of an efficient load balancing algorithm. The load can be CPU load, memory capacity, delay or network load. Load balancing is the process of distributing the load among various nodes of a distributed system to improve both resource utilization and job response time while also avoiding a situation where some of the nodes are heavily loaded while other nodes are idle or doing very little work. Load balancing ensures that all processor in the system or every node in the network does approximately the equal amount of work at any instant of time.

Konya bölgesi ülkemizde şeker pancarı üretiminin 1/3’ ünden fazlasını elinde tutan oldukça önemli bir şeker pancarı üretim alanıdır. 2015-2017 yılları arasında bu bölgede 866 tarlada yapılan surveyler sonucu 691’inde özellikle hasata yakın geç dönemde ve tüm dönemlerde kök çürüklükleri tespit edilmiş, bunlar arasında da en çok Rhizoctonia etmenine rastlandığı bildirilmiştir. Yapılan morfolojik tanılama, izolasyon, mikroskopik gözlem, ITS rDNA bölgesinin sekans verileri ile yapılan moleküler yöntemlerle etmen Rhizoctonia spp. olarak tanımlanmıştır. Bazı fungisitlerin patojene etkisini tespit etmek amacıyla yapılan çalışmamızda, elde edilen izolatlardan en yaygın ve virülensliği en fazla olan Rhizoctonia solani AG-2-2-IIIB’ ye ait 2G izolatı ile Azoxystrobin, Fludioxonil, Flutolanil, Tolclofos-methly, Pyraclostrobin+Epoxiconazole, Difenoconazole+Propiconazole, Spiroxamine+Prothiocona ve Sedaxane+Fludioxonil+Metalaxyl-M etken maddeli 8 farklı fungisit petri ve saksı denemelerinde kullanılmıştır. Petri misel denemesinde tespit edilen engelleme dozları ile beraber firmaların önerdiği tam doz, çift kat doz, yarı dozlar saksı denemesinde kullanılmıştır. Çalışmalar sonucunda, en etkili fungisit ve dozu olarak Azoxystrobin’ un çift kat dozu ve Sedaxane+Fludioxonil+Metalaxyl-M’ ın tam dozu olduğu tespit edilirken; saksı çalışmalarında, önerilen dozun 2 katı dozlarının daha etkili bulunması patojenin bu ilaçlara karşı direnç geliştirmiş olmasını düşündürmektedir.﻿﻿

Ağız araştırmaları dil çalışmalarının en önemli unsurlarından biridir. Ağızlar; yazı dilinden farklı olarak gelişen, dilin zenginliğini ortaya koyan ve dili besleyen temel kaynaklardır. Bu bakımdan yazı dilinde bulunmayan pek çok unsuru ağızlarda bulmak mümkündür. Anadolu ağızları da Türkçenin zenginliğini ortaya koymakta ve günümüz yazı dilinde bulunmayan eski kullanımları barındırmaktadır. Fakat günümüzde ağızları olumsuz yönde etkileyen birçok unsur vardır. Özellikle teknolojinin gelişmesi, eğitim seviyesinin yükselmesi, yazı dilinin yaygınlaşması ağızları etkilemekte ve dili besleyen bu kaynakların yavaş yavaş yok olmasına ve yazı dilinde bulunmayan ama ağızlarda kullanılan bazı kelimelerin unutulmasına neden olmaktadır. Bu sebeple bu kaynakların araştırılması ve unutulmaya yüz tutan kelimelerin derlenerek kayda geçirilmesi önemlidir. Bu konuda yapılan en önemli çalışma olan Derleme Sözlüğü’dür ve son yıllarda Derleme Sözlüğü’ne katkı sağlamak amacıyla bu sözlükte yer almayan ama Anadolu ağızlarında kullanılan pek çok kelimenin derlemesi yapılmıştır. Bu amaç doğrultusunda bu çalışmada Konya’nın Derebucak ilçesine bağlı Gencek Mahallesi’nden derlenen ve Derleme Sözlüğü’ne katkı sağlayabilecek kelime ve deyimlerin üzerinde durulmuştur. Gencek’ten derlenen 80 sözcük (betçere, değesek, kengek gibi.) ve 11 deyim (betçeli konuşmak, çuluğu çıkmak, son baylığı vermek gibi.) Derleme Sözlüğü’ne katkı sağlayabilecek niteliktedir. Kelimeler ve deyimlerin anlamlarının daha kolay anlaşılabilmesi amacıyla sözcükler ve deyimler örnek cümlelerle birlikte verilmiştir. Örnek cümleler, standart alfabeye dayalı transkripsiyon yöntemine göre kaydedilmiştir. Çalışmanın hem Derleme Sözlüğü’ne hem de Türkiye Türkçesi ağız araştırmalarına katkı sağlayacağı düşünülmektedir.

Published: December 2020

The COVID-19 affected each and every industry sector around the world. Most of the
educational institutions of India as well as the world got affected very badly. It has forced worldwide lockdown and created an atrocious effect on student life. The COVID-19 affected all the sectors in (T) the whole world, especially the education system around the world. In India, approximately 32 crore students stopped going to schools and colleges, and other training activities did not happen properly due to COVID-19. The outbreak of COVID19 and associated impact on student movement has advised us that change is inevitable in the education system. It has given a challenge and an opportunity to all the educational institutions to find a solution by determining suitable platforms and techniques for effective implementation of quality educational services, which has not been used before. Accordingly, the education sector has been fighting to continue its existence with a different approach by digitizing the challenges to wash the threat of the sickness. This paper also highlights some measures taken by Govt. of India to provide unified education in the country. Both the positive and negative impacts of COVID-19 are discussed and some productive suggestions are specified to bring out the educational activities back to normal during this bad situation. In this situation, every institution has adopted an online education model using information communication and computation technology (ICCT) due to COVID-19. This analysis is about how these technologies can help institutions continue online education and to know the student’s capability to take-up online education. The major discussion is to know whether an institution can continue online education for students in future days or not.
PUBLIC ADMINISTRATION AND THE CHALLENGE OF NATIONAL DEVELOPMENT IN NIGERIA: CHALLENGES AND PROSPECTS
Authors:   Department of Public Administration, Faculty of Management Science, Veritas University, Abuja, Shimawua Dominic
Published: December 2020

Contemporary Nigeria is plagued with the problems of widespread poverty, large-scale unemployment, technological backwardness, low capacity utilization, inadequate and decayed social and physicalinfrastructure, high incidence of diseases, high crime rate, among others. These disturbing socio-economicindicators in Nigeria are among the worst in the world. Ironically, these unpleasant indicators exist side-byside the country’s great national wealth and potentials, with an enviable stock of human resources whopossess knowledge, expertise and skills especially in the public service. Unfortunately, it appears these knowledgeable public servants are unable to serve as catalysts in the development of the nation. This situation makes the Nigerian case paradoxical. The objective of this study therefore is to identify the challenges preventing Nigerian public administration from playing its catalyzing role in the development of the country as well as to proffer possible solutions. One of the findings is that bribery and corruption are a bane of Nigerian public administration. In fact, they constitute a serious impediment to national development. The paper recommends, inter alia, the empowering of the anti-corruption institutions and introduction of information and communication technology in public governance. The paper submits that the label of poor performance and absence of excellence in the public service has the tendency to undermine development and good governance in Nigeria.
