Authors: Coelho Natália Lídia L. , Figueiredo Tatiane Fernandes , Figueiredo Rosa
Published: June 2023

Compreender o comportamento dos políticos e seus votos tem sido foco de diversos estudos na literatura. Trabalhos recentes, utilizando técnicas heurísticas para clusterização, apresentaram algumas análises sobre grupos de políticos, brasileiros e europeus, em votações de propostas que ocorreram em um determinado período de tempo. Nesse contexto, este trabalho propõe o uso de técnicas de Programação Linear Inteira para agrupamentos de políticos da Câmara dos Deputados. Os resultados obtidos permitiram uma análise dos fatores que possivelmente influenciaram, ou não, os votos de cada grupo de políticos criado.

Authors: Ramos Diogo F. S. , Mena-Chalco Jesús P.
Published: June 2023

Grafos temporais são uma extensão dos grafos convencionais para representar eventos que ocorrem no tempo. Neste trabalho introduzimos um algoritmo que calcula o conjunto de membros de uma rede que são influenciados direta ou indiretamente com custo computacional O(V C), tal qual encontrado na literatura, mas com média menor. Formalmente definimos o conceito de Território Causal. Realizamos experimentos sobre os primeiros cinco anos de carreira dos pesquisadores presentes na DBLP. Os principais resultados indicam que: (i) o tamanho dos territórios causais vem aumentando; (ii) a concentração da quantidade de pesquisadores potencialmente influenciados vem se estabilizando; e (iii) os pesquisadores tem aumentado o seu alcance de influência.

On the conformable colorings of k-regular graphs
Authors: Faria Luerbio , Nigro Mauro , Sasaki Diana
Published: June 2023

In 1988, Chetwynd and Hilton defined conformable vertex colorings when trying to characterize the vertex colorings induced by a (∆ + 1)-total coloring. Anticonformable colorings were used to characterize the subcubic conformable graphs. A graph G is anticonformable if it has a (∆ + 1)-vertex coloring such that the number of color classes (including empty color classes) with the same parity as |V| is at most def(G) = ∑v∈V (∆− dG(v)). The only connected subcubic not anticonformable graph is the triangular prism graph L3. In this paper, we prove that if k is even, then every k-regular graph is not anticonformable; and if k ≥ 3 is odd, then there is a not anticonformable graph Hk, where H3 = L3.

Um algoritmo genético híbrido para o problema do caixeiro viajante com tempos de liberação
Authors: Soares Gabriel , Bulhões Teobaldo , Bruck Bruno
Published: June 2023

O foco deste artigo é uma variante do problema do caixeiro-viajante clássico, no qual cada cliente está associado a um tempo de liberação indicando quando o produto solicitado estará disponível no depósito. O problema envolve o uso de um único veículo sem capacidade para atender todos os clientes fazendo múltiplas viagens. No entanto, o veículo não pode iniciar uma rota até que todos os produtos associados às demandas da rota tenham sido liberados, levando a possíveis tempos de espera antes de iniciar a próxima rota. O objetivo é minimizar o tempo de término da última rota, que se refere ao tempo que o veículo leva para retornar ao depósito após atender todas as demandas. Para resolver este problema, este artigo propõe um algoritmo genético híbrido que inclui técnicas mais avançadas para avaliar indivíduos e promover diversidade na população. Além disso, é introduzido um novo algoritmo de split com programação dinâmica, que converte a sequência de visita do cliente em um conjunto ótimo de rotas que mantém a sequência. O algoritmo conseguiu encontrar a solução ótima para todas as 154 instâncias com ótimos conhecidos e encontrou melhores limites superiores para 364 instâncias, em significativamente menos tempo quando comparado ao algoritmo de estado-da-arte.

Authors: Britto Larissa F. S. , Pacífico Luciano D. S.
Published: June 2023

User opinion analysis is an important tool to guide the decision-making process of independent game developers and game studios, once such activity leads to better product development towards the user satisfaction. Sentiment Analysis (SA) techniques have been widely used by companies to discover what customers are saying about their products, and the game industry could also benefit from such research field, once user feelings about a video game may have a relevant impact in retention and revenues. In this work, a thorough analysis on user acceptance in video games is performed by means of Natural Language Processing and SA approaches, where game reviews are exploited to understand what are the most relevant topics users are taking into consideration when they evaluate a game. A Sentiment Classification approach is performed, and the proposed methodology is discussed step-by-step, seeking out to motivate further researches in the field. Also, a new data set is proposed, composed by game reviews written in Brazilian Portuguese, given the relevance of Brazilian market in game industry.

Authors: Torquette Gustavo P. , Nunes Victor S. , Paiva Pedro Y. A. , Neto Lourenço B. Cunha , Lorena Ana C.
Published: June 2023

Some recent pieces of work in the Machine Learning (ML) literature have demonstrated the usefulness of assessing which observations are hardest to have their label predicted accurately. By identifying such instances, one may inspect whether they have any quality issues that should be addressed. Learning strategies based on the difficulty level of the observations can also be devised. This paper presents a set of meta-features that aim at characterizing which instances of a dataset are hardest to have their label predicted accurately and why they are so, aka instance hardness measures. Both classification and regression problems are considered. Synthetic datasets with different levels of complexity are built and analyzed. A Python package containing all implementations is also provided.
New State-of-the-Art for Question Answering on Portuguese SQuAD v1.1
Authors: da Silva E. H. M. , Laterza J. , Faleiros T. P.
Published: June 2023

In the Natural Language Processing field (NLP), Machine Reading Comprehension (MRC), which involves teaching computers to read a text and understand its meaning, has been a major research goal over the last few decades. A natural way to evaluate whether a computer can fully understand a piece of text or, in other words, test a machine’s reading comprehension, is to require it to answer questions about the text. In this sense, Question Answering (QA) has received increasing attention among NLP tasks. For this study, we fine-tuned BERT Portuguese language models (BERTimbau Base and BERTimbau Large) on SQuAD-BR - the SQuAD v.1.1 dataset translated to Portuguese by the Deep Learning Brazil group - for Extractive QA task, in order to achieve better performance than other existing models trained on the dataset. As a result, we accomplished our objective, establishing the new state-of-the-art on SQuAD-BR dataset using BERTimbau Large fine-tuned model.
One-Class Recommendation through Unsupervised Graph Neural Networks for Link Prediction
Authors: Gôlo Marcos P. S. , Moraes Leonardo G. , Goularte Rudinei , Marcacini Ricardo M.
Published: June 2023

Recommender systems play a key role in every online platform to provide users a better experience. Many classic recommendation approaches might find issues, mainly modeling user relations. Graphs can naturally model these relations since we can connect users interacting with items. On the other hand, when we model user-item relations through graphs, we do not have interactions between all users and items. In addition, there are few non-recommendation interactions, which makes it challenging to cover this scope. Also, the scope of what will not be recommended for the user is greater than what will be recommended. An alternative is One-Class Learning (OCL) which is able to recommend or not an item for a user only to train with recommendations, mitigating the needing to cover the scope of non-recommendations. However, OCL and Recommender Systems need appropriate, adequate, and robust representations to perform the recommendations in the best possible way. Therefore, we propose the one-class recommendation via representations learned by unsupervised graph neural networks (GNNs) for link prediction to generate a more robust and meaningful representation of users and items. In the results, our GNNs for link prediction outperform other methods to represent the users and items in the one-class recommendation. Furthermore, our proposal also outperforms a GNN for link prediction. Thus, our proposal recommended better and learned more robust representations.

Published: June 2023

The prediction of market price movement is an essential tool for decision-making in trading scenarios. However, there are several candidate methods for this task. Metalearning can be an important ally for the automatic selection of methods, which can be machine learning algorithms for classification tasks, named here classification algorithms. In this work, we present an empirical evaluation of the metalearning application for the classification algorithms selection in the market movement prediction task. Different setups and metrics were evaluated for the meta-target selection. Cumulative return was the metric that achieved the best meta and base-level results. According to the experimental results, metalearning was a competitive selection strategy for predicting market price movement.
Tractable Classification with Non-Ignorable Missing Data Using Generative Random Forests
Authors: Villanueva Julissa , Mauá Denis
Published: June 2023

Missing data is abundant in predictive tasks. Typical approaches assume that the missingness process is ignorable or non-informative and handle missing data either by marginalization or heuristically. Yet, data is often missing in a non-ignorable way, which introduce bias in prediction. In this paper, we develop a new method to perform tractable predictive inference under non-ignorable missing data using probabilistic circuits derived from Decision Tree Classifiers and a partially specified response model of missingness. We show empirically that our method delivers less biased (probabilistic) classifications than approaches that assume missing at random and are more determinate than similar existing overcautious approaches.

Published: June 2023

An electrolytic copper foil uses titanium drums, which exhibit excellent corrosion resistance and can produce thin electrodeposited copper foils. The appropriate technology for producing thin copper foils is required as electronic products become lighter, thinner, shorter, and smaller. Thus, the importance of titanium drum manufacturing technology, which affects the specifications of electrolytic copper foils, is emphasized. In this study, thermo-elastic-plastic analysis is performed to select an appropriate range of welding process parameters for titanium drums. In addition, using a range of welding process variables derived from analysis, GBO and GPS algorithms, which are optimization algorithms, are developed to derive objective and restriction functions as well as to select the optimal algorithm.

Published: June 2023

Coronavirus disease 2019 (COVID-19) is a viral infection produced by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus epidemic, which was declared a global pandemic in March 2020. The World Health Organization has recorded around 43.3 billion cases and 59.4 million casualties to date, posing a severe threat to global health. Severe COVID-19 indicates viral pneumonia caused by the SARS-CoV-2 infections, which can induce fatal consequences, including acute respiratory distress syndrome (ARDS). The purpose of this research is to better understand the COVID-19 and ARDS pathways, as well as to find targeted single nucleotide polymorphism. To accomplish this, we retrieved over 100 patients’ samples from the Sequence Read Archive, National Center for Biotechnology Information. These sequences were processed through the Galaxy server next generation sequencing pipeline for variant analysis and then visualized in the Integrative Genomics Viewer, and performed statistical analysis using t-tests and Bonferroni correction, where six major genes were identified as DNAH7, CLUAP1, PPA2, PAPSS1, TLR4, and IFITM3. Furthermore, a complete understanding of the genomes of COVID-19-related ARDS will aid in the early identification and treatment of target proteins. Finally, the discovery of novel therapeutics based on discovered proteins can assist to slow the progression of ARDS and lower fatality rates.
Computational approaches for molecular characterization and structure-based functional elucidation of a hypothetical protein from Mycobacterium tuberculosis
Authors: Saikat Abu Saim Mohammad
Published: June 2023

Adaptation of infections and hosts has resulted in several metabolic mechanisms adopted by intracellular pathogens to combat the defense responses and the lack of fuel during infection. Human tuberculosis caused by Mycobacterium tuberculosis (MTB) is the world’s first cause of mortality tied to a single disease. This study aims to characterize and anticipate potential antigen characteristics for promising vaccine candidates for the hypothetical protein of MTB through computational strategies. The protein is associated with the catalyzation of dithiol oxidation and/or disulfide reduction because of the protein’s anticipated disulfide oxidoreductase properties. This investigation analyzed the protein's physicochemical characteristics, protein-protein interactions, subcellular locations, anticipated active sites, secondary and tertiary structures, allergenicity, antigenicity, and toxicity properties. The protein has significant active amino acid residues with no allergenicity, elevated antigenicity, and no toxicity.
Insight from sirtuins interactome: topological prominence and multifaceted roles of SIRT1 in modulating immunity, aging and cancer
Authors: Zulkifli Nur Diyana , Zulkifle Nurulisa
Published: June 2023

The mammalian sirtuin family, consisting of SIRT1–SIRT7, plays a vital role in various biological processes, including cancer, diabetes, neurodegeneration, cardiovascular disease, cellular metabolism, and cellular homeostasis maintenance. Due to their involvement in these biological processes, modulating sirtuin activity seems promising to impact immune- and aging-related diseases, as well as cancer pathways. However, more understanding is required regarding the safety and efficacy of sirtuin-targeted therapies due to the complex regulatory mechanisms that govern their activity, particularly in the context of multiple targets. In this study, the interaction landscape of the sirtuin family was analyzed using a systems biology approach. A sirtuin protein-protein interaction network was built using the Cytoscape platform and analyzed using the NetworkAnalyzer and stringApp plugins. The result revealed the sirtuin family's association with numerous proteins that play diverse roles, suggesting a complex interplay between sirtuins and other proteins. Based on network topological and functional analysis, SIRT1 was identified as the most prominent among sirtuin family members, demonstrating that 25 of its protein partners are involved in cancer, 22 in innate immune response, and 29 in aging, with some being linked to a combination of two or more pathways. This study lays the foundation for the development of novel therapies that can target sirtuins with precision and efficacy. By illustrating the various interactions among the proteins in the sirtuin family, we have revealed the multifaceted roles of SIRT1 and provided a framework for their possible roles to be precisely understood, manipulated, and translated into therapeutics in the future.

Immunologists have activated T cells in vitro using various stimulation methods, including phorbol myristate acetate (PMA)/ionomycin and αCD3/αCD28 agonistic antibodies. PMA stimulates protein kinase C, activating nuclear factor-κB, and ionomycin increases intracellular calcium levels, resulting in activation of nuclear factor of activated T cell. In contrast, αCD3/αCD28 agonistic antibodies activate T cells through ZAP-70, which phosphorylates linker for activation of T cell and SH2-domain-containing leukocyte protein of 76 kD. However, despite the use of these two different in vitro T cell activation methods for decades, the differential effects of chemical-based and antibody-based activation of primary human T cells have not yet been comprehensively described. Using single-cell RNA sequencing (scRNA-seq) technologies to analyze gene expression unbiasedly at the single-cell level, we compared the transcriptomic profiles of the non-physiological and physiological activation methods on human peripheral blood mononuclear cell–derived T cells from four independent donors. Remarkable transcriptomic differences in the expression of cytokines and their respective receptors were identified. We also identified activated CD4 T cell subsets (CD55+) enriched specifically by PMA/ionomycin activation. We believe this activated human T cell transcriptome atlas derived from two different activation methods will enhance our understanding, highlight the optimal use of these two in vitro T cell activation assays, and be applied as a reference standard when analyzing activated specific disease-originated T cells through scRNA-seq.
Cell line-specific features of 3D chromatin organization in hepatocellular carcinoma
Authors: Kim Yeonwoo , Yang Hyeokjun , Lee Daeyoup
Published: June 2023

Liver cancer, particularly hepatocellular carcinoma (HCC), poses a significant global threat to human lives. To advance the development of innovative diagnostic and treatment approaches, it is essential to examine the hidden features of HCC, particularly its 3D genome architecture, which is not well understood. In this study, we investigated the 3D genome organization of four HCC cell lines—Hep3B, Huh1, Huh7, and SNU449—using in situ Hi-C and assay for transposase-accessible chromatin sequencing. Our findings revealed that HCC cell lines had more long-range interactions, both intra-and interchromosomal, compared to human mammary epithelial cells (HMECs). Unexpectedly, HCC cell lines displayed cell line-specific compartmental modifications at the megabase (Mb) scale, which could potentially be leveraged in determining HCC subtypes. At the sub-Mb scale, we observed decreases in intra-TAD (topologically associated domain) interactions and chromatin loops in HCC cell lines compared to HMECs. Lastly, we discovered a correlation between gene expression and the 3D chromatin architecture of SLC8A1, which encodes a sodium-calcium antiporter whose modulation is known to induce apoptosis by comparison between HCC cell lines and HMECs. Our findings suggest that HCC cell lines have a distinct 3D genome organization that is different from those of normal and other cancer cells based on the analysis of compartments, TADs, and chromatin loops. Overall, we take this as evidence that genome organization plays a crucial role in cancer phenotype determination. Further exploration of epigenetics in HCC will help us to better understand specific gene regulation mechanisms and uncover novel targets for cancer treatment.
Saḫa (Yakut) Türklerinin Sözlü Kültür Ürünlerinde Evren Tasarımı
Authors: KESER Alper
Published: June 2023

Saḫalar, Baykal Gölü ve Angara Nehri çevresindeki bozkırlardan göç edip, Lena havzasını kendilerine yurt kılan Türk halkıdır. Onlar kendilerini tanımlamak için Saḫa ismini kullansalar da Rus ve Avrupa literatüründe Yakut olarak anılırlar. Günümüzde Rusya Federasyonu’na bağlı olarak Saḫa Yeri’nde (Yakutistan) yaşayan Saḫa (Yakut) Türkleri, sözlü kültürden yazılı kültüre oldukça geç bir zamanda, Rus Çarlığı’nın Ruslaştırma ve Hristiyanlaştırma politikası sonucu 19’uncu asırdan itibaren geçmiştir. Bu zamana kadar Saḫa (Yakut) Türklerinin kültürel birikimi sadece bellekte muhafaza edilmiş, söz ve ritüel aracılığıyla nesilden nesile aktarılmıştır. Günümüzde sözlü ve yazılı kültür birikimleri dikkate alındığında Saḫa (Yakut) Türklerinin başta oloñḫo adı verilen kahramanlık destanları olmak üzere zengin bir anlatı külliyatına sahip olduğu görülmektedir. Fakat Saḫa (Yakut) Türklerinin Türkiye’den çok uzak bir coğrafyada yaşamaları, uzun yıllar Sovyetler Birliği çatısı altında idare edilmeleri, kaynakların çoğunluğunu Rusça ve Saḫa (Yakut) Türkçesi ile yazılmış eserler oluşturması gibi etmenler sebebiyle, Türkiye’de Saḫa (Yakut) Türkleri ile ilgili çalışmalar sınırlı sayıda kalmıştır. Dolayısıyla Saḫa (Yakut) Türklerinin kültürel birikimiyle ilgili yeni çalışmaların yapılması bir gereklilik arz etmektedir. Ele alınan çalışmada da öncelikli olarak konuyla ilgili eksikliğin giderilmesine bir katkı sunmak amaçlanmıştır. Bu amaç doğrultusunda toplumların kültürel kodlarını içerisinde barındıran, ortak amaç ve değerler merkezinde toplum mensuplarını bir araya getiren sözlü kültür ürünleri üzerinden Saḫa (Yakut) Türklerinin evren tasarımı incelenmiş ve geleneksel dünya görüşü aydınlatılmaya çalışılmıştır. Metin merkezli yürütülen çalışmanın sonucunda Saḫa (Yakut) Türklerinin evren tasarımı ile bozkır kültürü Türk evren anlayışının örtüştüğüne kanaat getirilmiştir.
Syncope Through Gemination in Turkish: Exploring the Role of Sufficiently Identical Flanking Consonants
Authors: İSKENDER Halil
Published: June 2023

This paper investigates the interplay of syncope and gemination in modern Standard Turkish, underlining the crucial function of sufficiently identical flanking consonants (SIFCs) in this process. Syncope, typified by the elimination of a vowel within specific phonological contexts, holds the potential to give rise to gemination. A thorough analysis of varied spoken language data uncovers the conditions that govern syncope, countering prevalent literature which postulates syncope as a lexical process; instead, our findings suggest it to be phonological in nature. Attention is then directed towards syncope-induced gemination, emphasizing the catalytic role of SIFCs. This focus further underscores the indispensable role that SIFCs perform in facilitating this complex process. Moreover, the unique interplay between syncope and the potential for gemination is systematically explored, disclosing intricate patterns of consonant interaction within the Turkish language. The findings suggest that Turkish phonology exhibits a compelling alignment with gemination language characteristics, yielding thought-provoking insights into phonological processes such as vowel deletion and consonant gemination. The results of this novel research initiative contribute significantly to the expanding body of studies on syncope and gemination, shedding light on the intricate interplay between the two in Turkish, while also providing insights for the examination of analogous phenomena in other languages.
The Hypophysics of Philosophical Nationalism
Authors: Dwivedi Divya ,   Philosophy Documentation Center
Published: June 2023

Is there a philosophical nationalism? Reading Fichte’s Addresses to the German Nation and its use by the Nazis, Derrida concluded that all nationalisms are philosophical and onto-theological as they are posited beyond race, biology, and nature. However, Fichte’s text reveals a specific form of racism that insists on biology and nature. Fichte’s racism is a species of “hypophysics,” a consecration of nature as value. His theory of language is simultaneously biological and spiritual, these two aspects flowing from a single geistige Naturgesetz (spiritual-natural-law) and determining the hypophysical unity of language, community and “philosophy” (as he defined it). The logic of such a hypophysics is misrecognized and left unaddressed in the conventional categories of “naturalism” and “biologism.” Further, hypophysical-logic is not onto-theo-logic (in Heidegger’s definition). This imposes new questions for the history and future of philosophy: how does hypophysics enter philosophy; can there be philosophy without hypophysics and its attendant racisms?

Published: June 2023

Statement of the problem

Temporomandibular disorder (TMD) represents a common group of disorders related to the impairment of the temporomandibular joints and the associated neuro-muscular system, which commonly present with features such as pain in the orofacial region, headache, joint sounds, and disturbances in jaw movements. Recently, botulinum toxin type-A (BTX-A) has increasingly been used as an adjuvant treatment for TMD.

Purpose of the study

This retrospective study aims to evaluate the effectiveness of BTX-A for the management of myogenous TMD and its potential to be included as a first line of treatment.

Materials and methods

A retrospective search was carried out through the Oral and Maxillofacial Department’s logbook from January 1, 2016, to December 31, 2020. Patients who received BTX-A for the management of myogenous TMD were identified and their hospital electronic records were accessed.

Results

From January 1, 2016, to December 31, 2020, 60 patients were diagnosed with myogenous TMD and treated conservatively together with intramuscular injections of BTX-A. Forty-five patients (75%) reported improvement in pain levels, of whom 10 (17%) reported complete resolution of pain. Fifteen patients (25%) reported no improvement in pain levels, of whom four (7%) reported transient improvement in pain levels lasting four weeks. A mean improvement of 50% was reported in terms of self-perceived pain levels. No adverse effects from BTX-A treatment were reported.

Conclusion

Although BTX-A shows great potential to be included as a first line of treatment for myogenous TMD, more high-quality research with larger sample sizes, minimal bias, and longer follow-up periods is needed.

Authors: ERKAN Mehmet
Published: June 2023

Bu araştırmada Kuzey Kıbrıs Türk Cumhuriyeti ortaokullarında uygulanmakta olan Din Kültürü ve Ahlak Bilgisi (DKAB) ders kitaplarının öğrenme-öğretme sürecine katkısı ve yeterliğinin öğretmen görüşleri çerçevesinde değerlendirilmesi amaçlanmıştır. Araştırmanın evrenini 2020-2021 eğitim öğretim yılında KKTC’deki devlet ortaokullarında görevli olan tüm DKAB öğretmenleri oluşturmaktadır. Araştırma 2020-2021 eğitim öğretim yılında KKTC’de görevli olan DKAB öğretmenlerinden 14’ü aracılığıyla gerçekleştirilmiştir. Nitel bir araştırma deseni ile incelenen araştırmanın verileri yarı yapılandırılmış görüşme sorularıyla elde edilmiştir. Araştırmada ulaşılan bulgular içerik analizine göre analiz edilerek yorumları yapılmış ve tartışma kısmına yer verilmiştir. KKTC’de DKAB ders kitaplarının yeterliği, ders kitaplarının öğretim sürecine katkısı ve ders kitaplarının olumlu-olumsuz yönleri gibi konularda KKTC’de yapılmış başka bir çalışmaya rastlanmamıştır. Dolayısıyla bu araştırmanın eğitim öğretim açısından program geliştirme ve ders kitaplarının hazırlanması süreçlerinde literatüre önemli ölçüde katkı sağlayacağı düşünülmektedir. Bir eğitim materyali olarak DKAB ders kitaplarının amacına hizmet etmesi için hedef kitlesine yönelik olması gerekir. Bu araştırmada DKAB ders kitaplarının amacına nasıl hizmet ettiği ve ders kitaplarıyla ilgili yaşanan problemler yer almaktadır. Araştırma sonuçlarına göre KKTC’de uygulanmakta olan DKAB ders kitaplarında teknik hataların bulunduğu, anlatım ve kavramlar açısından kitapların öğrenci seviyelerinden uzak olduğu, kazanımları yerine getirme açısından ders süresi ve öğretim programıyla ders kitaplarının uyumlu olmadığı ortaya çıkmıştır. KKTC’de uygulanmakta olan DKAB ders kitapları genel olarak Türkiye’deki DKAB kitaplarından faydalanılarak hazırlanmıştır. Her ne kadar benzerlikler bulunsa da Türkiye ve KKTC toplumlarının ayrı bir sosyolojik geçmişleri olduğu bir gerçektir. Son yıllarda toplumsal yapıya uygun olması açısından DKAB ders kitaplarında bazı düzenlemeler yapılmış fakat yapılan düzenlemeler yeterli olmamıştır. Bu nedenle DKAB ders kitaplarındaki bu olumsuz intibaın eğitim öğretimi önemli ölçüde etkilediği dolayısıyla DKAB ders kitaplarının KKTC toplumuna yönelik olarak yeniden geliştirilmesi gerekmektedir.

Sözlü halk edebiyatı ürünleri içerisinde taşıdığı zengin malzeme itibariyle önemli bir yere sahip olan masallar, ait oldukları milletin maddi manevi değerlerini, gelenek göreneklerini ve inanç sistemini, her türlü kültürel öğeyi taşıyan anonim ürünlerdir. Masallar parçalanamayan en küçük yapı taşı ollarak kabul edilen motiflerin birleşimiyle meydana gelirler. Masallar yüzyıllardır farklı coğrafyalarda yayılım göstererek varlığını sürdürürler. İşte bu farklı coğrafyalarda yayılım gösteren masalların ortak noktalarının karşılaştırılması istenmiştir. Masallar üzerindeki çalışmalar önceleri sadece metinlerin ortaya konulması şeklinde gelişmişti. Fakat bu metinlerin inceleme konusu olduğu zaman yararlanmayı kolaylaştırmak için bazı tedbirlerin alınması gerekiyordu. Farklı ülkelerden derlenen masalların benzer masalların bir araya gelmesi durumunda hepsinin ortak bir ad veya numara ile anılması, o masallardan yararlanılmasını kolaylaştırmıştır. Stith Thompson tarafından geliştirilen “masal tip indeksi halkbilimi analizlerine kaynak olarak kullanılmaktadır. Bu çalışmamız çeşitli yerleşim yerlerinden derlenen, 49 adet Kıbrıs Türk Masalı, Sttıth Thompson’un Halk Edebiyatı Katoloğuna göre motiflerin sıralaması yapılmıştır. Amacımız bu alanda çalışma yapmak isteyen araştırmacılara makalemizin bir yol gösterici olmasıdır. Sahada derlenen 49 masal metninde bulunan masallara motif indeksine göre numara verilmiştir. İncelediğimiz 49 masal metninde, Katologda yer alan mitolojik motif ve mizahi motife rastlanmamıştır. Hayvan motifleri, sihir motifleri, harkulâdelik motifleri dikkat çekici şekilde çok olan motifleridir. Anormal zulüm motifi ise çok az yer almaktadır.
