Promoting Ethno-tourism in the Costa Rican Indigenous Territories to Achieve Economic Prosperity
Authors: Llobet Adriana
Published: August 2024

This research examines the impact of ethno-tourism on indigenous communities in Costa Rica and its potential for economic prosperity. Costa Rica, a prominent Central American tourist destination, derives a significant portion of its GDP from tourism. Ethno-tourism, which emphasizes the cultural and traditional practices of local people, has emerged as a growing sector within this industry. Despite Costa Rica's overall developmental success, its indigenous populations remain economically and socially marginalized, with poorer health and limited access to essential services compared to the general population. This study examines successful ethno-tourism initiatives among the Shuar in Ecuador and the Mapuche in Chile, drawing parallels with Costa Rican indigenous groups. Fieldwork in Costa Rican indigenous territories shows that communities involved in ethno-tourism have better living conditions. However, these communities are often exploited by large tourist agencies due to limited financial and technological knowledge. The study recommends enhancing legal protections for indigenous lands, and offering financial literacy and technology courses. Additionally, it suggests creating a non-profit organization to help indigenous communities promote their tourism initiatives digitally, ensuring sustainable growth.

Large-Scale Assessments for Learning: A Human-Centred AI Approach to Contextualizing Test Performance
Authors: Guo Hongwen , Johnson Matthew , Ercikan Kadriye , Saldivia Luis , Worthington Michelle
Published: August 2024

Large-scale assessments play a key role in education: educators and stakeholders need to know what students know and can do, so that they can be prepared for education policies and interventions in teaching and learning. However, a score from the assessment may not be enough—educators need to know why students got low scores, how students engaged with the tasks and the assessment, and how students with different levels of skills worked through the assessment. Process data, combined with response data, reflect students’ test-taking processes and can provide educators such rich information, but manually labelling the complex data is hard to scale for large-scale assessments. From scratch, we leveraged machine learning techniques (including supervised, unsupervised, and active learning) and experimented with a general human-centred AI approach to help subject matter experts efficiently and effectively make sense of big data (including students’ interaction sequences with the digital assessment platform, such as response, timing, and tool use sequences) to provide process profiles, that is, a holistic view of students’ entire test-taking processes on the assessment, so that performance can be viewed in context. Process profiles may help identify different sources for low performance and help generate rich feedback to educators and policy makers. The released National Assessment of Educational Progress (NAEP) Grade 8 mathematics data were used to illustrate our proposed approach.
Polymorphisms in the Growth Hormone Gene and Their Association with Pre-pullet Body Weight in Kuttanad Ducks of Kerala, India
Authors: Sahana V.N. , Abraham Bindya Liz
Published: August 2024

Background: Kuttanad ducks are dual purpose native ducks found in Kerala state of India. Identification of single nucleotide variations in candidate genes like growth hormone gene and exploring their association with body weight at grower and pre-pullet stages is essential for the marker assisted selection of breeder ducks for genetic improvement. Methods: Genomic DNA was extracted from blood samples collected from 101 Kuttanad ducks. PCR-amplification of two duck growth hormone gene (dGH) loci viz, exon 3 and partial intron 3 (227 bp), exon 5 and partial intron 4 (366 bp) were undertaken using custom-synthesised primers. The 366 bp region was genotyped using Single Strand Conformation Polymorphism. The 227 bp region was genotyped using DNA pooling assay to yield a 139 bp product for subsequent High-Resolution Melting analysis. The association of dGH genotypic variants for these loci with fortnightly body weight at pre-pullet stages up to 16 weeks of age was analysed. Result: In the 366 bp fragment, GG and GA genotypes were revealed with one novel SNP (g 74G greater than A). The GG homozygotes had significantly higher body weight at all stages from two to 14 weeks of age (p≤0.01). A novel SNP (g 71A greater than G) was revealed at the 139 bp locus within the 227 bp region with three genotypes viz., AA, AG and GG. The GG homozygotes had significantly higher body weight at six, 14 and 16 weeks of age (p≤0.05). The study revealed that dGH polymorphic loci have jointly contributed to the variation in growth and hence can be used as markers for the primary selection of growers at sixth week of age followed by their secondary selection at 14-16 weeks of age during the multi-stage selection programmes for breeder ducks.

Published: August 2024

Tez çalışmasında ortaokul öğrencilerinin matematik başarısını ve problemi yansıtıcı düşünce ile ifadesini etkileyen faktörlerden duyuşsal özelliklerinin, problem pratiği yapmanın ve devamsızlıklarının etkisi incelenecektir. Öğrencilerin derse olan azim, hazır bulunuşluluk, öz disiplin, genel olarak okula yönelik tutumları, ilgisi ve okula gitme isteği gibi duyuşsal özellikler, eğitimin temelini oluşturan önemli etmenlerdir , matematik eğitiminde de ve düşünce yapısının oluşmasında önemli bir yere sahiptir. Matematiğe yönelik ilgi, matematiğe yönelik motivasyon, matematiğe ilişkin kaygı, matematikte kendini yeterli görme, matematikte özgüven, okula ait olma duygusu ve matematik derslerindeki sınıf disiplini ve ortamı da öğrencinin matematikteki duyuşsal özelliklerindendir. Derste gördükleri konular ile ilgili problem pratiği yapmaları da problemi günlük hayata aksettirmelerine faydalı olacaktır. Problem çözme sadece karşılaşılan belirli bir zorluğun ya da güçlüğün üstesinden gelmek için değil oluşabilecek yeni problemler karşısında ileri çalışmaların yapılması ve buluşların gerçekleştirilmesi için de önemli bir gereksinimdir. Matematik öğrenirken farklı ve çeşitli problem türleri ile uğraşmak, onları çözmek için yaklaşım ve stratejiler geliştirmek gerekmektedir. Derslere karşı devamsızlık azaldıkça da, öğrencilerin öğrendikleri bilgileri ilişkilendirmeleri kolaylaşacak ve konulara daha adapte olmasını sağlayacaktır. Konuya, derse , okula adapte olmaları da öğrencilerin dersi daha iyi anlamalarını, problemi kendilerine has bir şekilde ifade etmelerini ve haliyle de matematik başarılarını etkileyecektir.
Bu üç önemli faktörün matematik başarısına ve probleme yönelik yansıtıcı düşünceye etki ettiği öngörülmektedir. Bu etkinin büyüklüğü bulanık mantık modelleme aracılığıyla belirlenecektir.
Çok Kriterli Karar Vermede Nötrosofik Critic ve Nötrosofik Waspas Entegre Yöntemi Temelli Mutluluk Düzeyi Belirleme Üzerine Bir Uygulama
Authors: Merkepçi Hamiyet
Published: August 2024

Bu çalışmada,Türkiye istatistik Kurumunun yürüttüğü ‘Yaşam Memnuniyeti Araştırması’ kapsamında yer alan, yaş gruplarına ve yıllara gore değişiklik gösteren mutluluk düzeyinin belirlenmesi problemine uygulanan, Nötrosofik Kritik ve Nötrosofik Waspas adlı yeni bir Çok Kriterli Karar Verme Yöntemi öneriyorum. Önerilen yöntem, iyi bilinen Waspas yönteminin temel adımlarını izler, ancak öznitelik değerlerinin tek değerli nötrosofik kümeler kullanılarak ifade edilmesi bakımından klasik durumdan farklıdır. Ayrıca, seçim kriterlerinin ağırlıklarının belirlenmesi karar vericinin insiyatifine bırakılmamakta, bunun yerine iyi bilinen critic yönteminin temel adımları kullanılmaktadır. Sunulan mutluluk düzeyi belirleme probleminde, alternatifler, 2003-2022 yılları ve kriterler, 18-65+ yaş arası bireylerdir.. Bu makalede amacım, 2003 yılından günümüze kadar her yıl, belirlenen yaş gruplarında mutluluk düzeyi ölçümünü, yaygın olarak kullanılan entegre bir Çok Kriterli Karar Verme modeli ile tek değerli nötrosofik kümeler alanına genişletmektir. Böylece, öznitelik değerleri daha büyük bir belirsizlik kümesiyle başa çıkabilir. Nötrosofik küme teorisinin ifade gücünden yararlanarak önerilen yaklaşımın, karar vericiye, yeterli ve kesin bilgi eksikliği, algı farklılıkları, dil değişkenleri ve kişisel görüşler gibi çeşitli nedenlerden kaynaklanan belirsizlikleri yönetebilecek modeller geliştirmesine yardımcı olacağına inanıyorum.

Published: August 2024

Today, the negative impact of charging on the grid is becoming a major concern as the number of electric vehicles increases. The charging topologies such as V2G, V2H and V2V are being studied to solve this problem. The most critical issue in this context is the design and use of appropriate infrastructure and equipment. In this study, firstly a low-cost and high-efficiency non-isolated bidirectional DC-DC converter suitable for DC charging stations is designed. The designed converter was analysed both by analytical methods and by operating at low powers. Secondly, a real-world implementation of V2V and V2H topologies has been performed using these designed converters. In the application study, a DC charging station model was created by using 4 of these converters as charging units. The 90-minute operation of the designed charging station was realised according to a rule-based algorithm. Accordingly, it has been shown that the efficiency of the non-isolated bidirectional DC-DC converter designed is 95%. It is also proved that 54.16% of the EVs load can be shifted to off-peak time period using V2V topology in real world application. According to the results, it is understood that the isolated and high-power version of the designed converter is suitable for charging stations.

Published: August 2024

İş birliği, eğitsel problemlere çözüm bulmada etkili bir yöntem olarak görülmekte olup, öğretmenler arası iş birliği öğrencilere fayda sağlamakla kalmayıp eğitimciler için de olumlu sonuçlar doğurur. Öğretmenler ve uzmanlar arasında gönüllü katılım ile yapılan iş birliği için paydaşların iş birliğine yönelik düşüncelerinin olumlu olması gerekmektedir. Bu bağlamda araştırmanın amacı özel eğitim öğretmenlerinin iş birliği kavramına yönelik bilişsel yapılarının tespit edilmesidir. Öğretmenlerin iş birliği ile ilgili düşüncelerini anlamak için araştırmada "Kelime İletişim Testi (KİT)" kullanılmıştır. Araştırmanın çalışma grubunu, MEB’e bağlı devlet okullarında ve RAM’larda görev yapan özel eğitim öğretmenleri oluşturmuştur. Araştırmanın çalışma grubu amaçlı örneklem yöntemlerinden; ölçüt örneklem kullanılarak belirlenmiştir. Verilerin analiz edilmesinde anahtar kavramlarla ilişkilendirilen diğer kelime/kavramlar, aralarındaki anlamsal ilişkiler dikkate alınarak bir araya getirilerek ve gruplandırılmıştır. Araştırmaya katılan özel eğitim öğretmenleri tarafından "iş birliği" anahtar kavramıyla ilişkili olarak ifade edilen kavramlar ve kelimeler 10 kategoride gruplandırılmıştır. Bu kategoriler “duygu ve deneyimler, zorluk ve çaba, iletişim ve ilişki, hedef ve planlama, değerler ve etik, eğitim ve gelişim, performans ve başarı, iş ortamı, grup çalışması ve ortaklık, kurumsal ortaklıklar” şeklindedir. Araştırmaya katılan öğretmenlerden birbirinden farklı 147 kelime/kavram tespit edilmiştir. Öğretmenlerin farklı kavramlar yoluyla iş birliğini açıklamaları, iş birliğinin çok boyutlu bir kavram olduğunu ve her öğretmenin iş birliğini farklı açılardan anlamlandırdığını göstermektedir. Bu çeşitlilik, iş birliği anlayışının zenginliğini ve karmaşıklığını yansıtmaktadır. Bu nedenle, öğretmenlerin farklı bakış açılarını ve deneyimleri değerlendiren bir yaklaşımla iş birliğini desteklemek önemlidir. İlgili alan yazını destekleyecek şekilde bu araştırmanın sonuçları da iş birliği için gerekli olan özelliklerin, katılımda sorumluluk paylaşımı, iletişim, paylaşım ve birliktelik gibi kavramlar olduğunu ortaya koymaktadır.

Authors: Barış Yunus , Kobak Demir Mevhibe
Published: August 2024

This qualitative case study aims to examine the Rock-Paper-Scissors game within the framework of the relation and to determine the experiences and opinions of gifted students in the game development process. The study was conducted with 45 students studying at Science-Art Center. In the study, activities related to relations and their properties were carried out by the students. Within the scope of the activities, the Rock-Paper-Scissors game was analyzed within the framework of the concept of relation and developing a game was carried out. The experiences and opinions of the participants were obtained with an opinion form. The data obtained in the research were analyzed via content analysis. As a result of the research, although gifted students thought that developing games in the process was confusing, they found the application parts of the activity fun. They preferred to carry out the activity as a group. In addition, the mathematical concepts that the students used the most while developing the rock-paper-scissors game were relation, probability, sets, cartesian product and relation properties. The results of this study show that gifted students want to participate in different game development processes in the context of mathematics because it offers them the opportunity to socialize with people similar to their own level.

Published: August 2024

Cervical cancer is one of the leading causes of death in the female population and is the most common genital cancer. The rate at which women suffer from cervical cancer in developing countries is increasing on daily basis and Nigeria is no exception. This inspired the study to investigate factors affecting the uptake of Human Papillomavirus vaccines among young females in Anambra state, Nigeria.  Six Focus Group Discussions involving young females of 9 – 26 years were conducted in Awka, Nnewi, and Onitsha. A total of 60 respondents were used for the study. The study revealed that there were limited knowledge of the HPV vaccine among the respondents, hence, uptake of the vaccine was poor in the study population. The cost of the HPV vaccine, culture/religious influences were among the factors militating against the uptake of the vaccine. The result also highlighted possible ways of promoting HPV vaccine uptake which include subsidization of the vaccine cost or making it free, and prioritization of the vaccine and making it available in all hospital. In conclusion, there is need for social workers to engage in awareness creation on the important of utilizing HPV vaccine and also encourage parents to vaccinate their girl children.

Published: August 2024

This study aimed to compare the clinical and immunological changes and the degree of immunoglobulin A (IgA) deficiency during the follow-up period in patients with IgA deficiency, the most common group of primary immunodeficiency. The study included 234 patients whose serum immunoglobulin levels were checked for any reason and whose IgA level was found to be below the normal level for their age when they applied to the Pediatric Allergy and Immunology outpatient clinic of Eskişehir Osmangazi University Faculty of Medicine Hospital between 2011 and 2020. The patients were divided into two groups: selective IgA deficiency and partial IgA deficiency. Patients' complaints of hospital admission, history of sibling death, diagnosis of primary immunodeficiency in the family, history of atopic dermatitis, reasons for hospitalization, history of autoimmune disease, and total immunoglobulin E (IgE) levels were examined. It was determined that the history of sibling death was higher in the group with selective IgA deficiency than in the group with partial IgA deficiency (p=0.011). In the group with partial IgA deficiency, the history of atopic dermatitis and the elevation of total IgE were found to be higher than in the group with selective IgA deficiency (respectively; p=0.012, p=0.041). Comparative examination of selective IgA and partial IgA deficiency, which we see due to disorders in the mechanisms that regulate the specialized role of IgA, is important for early diagnosis of comorbid diseases and regulation of treatment protocols.
The uniqueness of ABCB5 as a full transporter ABCB5FL and a half-transporter-like ABCB5β
Authors: Gerard Louise , Gillet Jean-Pierre
Published: August 2024

The ABCB5 gene encodes several isoforms, including two transporters (i.e., ABCB5FL, ABCB5β) and several soluble proteins, such as ABCB5α which has been hypothesized to have a regulatory function. ABCB5FL is a full ABC transporter and is expressed in the testis and prostate, whereas ABCB5β is an atypical half-transporter with a ubiquitous expression pattern. ABCB5β has been shown to mark cancer stem cells in several cancer types. In addition, ABCB5β and ABCB5FL have been shown to play a role in tumorigenesis and multidrug resistance. However, ABCB5β shares its entire protein sequence with ABCB5FL, making them difficult to distinguish. It cannot be excluded that some biological effects described for one transporter may be mediated by the other isoform. Therefore, it is difficult to interpret the available data and some controversies remain regarding their function in cancer cells. In this review, we discuss the data collected on ABCB5 isoforms over the last 20 years and propose a common ground on which we can build further to unravel the pathophysiological roles of ABCB5 transporters.

Biocomposite is a type of composite consisting of a polymer matrix material and natural fiber reinforcement. Biocomposite technology, especially natural fibers, is currently in demand. The reasons are environmentally friendly, availability of many raw materials, low production costs, biodegradable, and recyclable.  Natural fibers used in the form of agricultural waste such as sugarcane bagasse and corn stalks while the mycelium of the fungus Pleurotus ostreatus and Lentinus squarrosulus are used as natural adhesives. The objectives of this research were to determine the effect of the type of white-rot fungus and the composition of the lignocellulosic material of agricultural waste that affects the quality of the resulting biocomposite board and to obtain the optimal type of white-rot fungus and the optimal composition of lignocellulosic material from agricultural waste to manufacture mycelium-based biocomposite board. The research method used a completely randomized design with ten treatments with three replications. The treatments used 2 types of mushroom (P. ostreatus and L. squarrosulus) with 2 types of Lignocellulosic materials (Sugarcane bagasse and Cornstalk) and each lignocellulosic material has 4 types of compositions (100%, 75%, 50%, and 25%). The main parameter was analyzed using Analysis of Variance (ANOVA) with an error rate of 5%, then further tested with post hoc Duncan at 95% confidence level to compare the effect between treatments. The results showed that the treatment of the type of fungus and the lignocellulosic material used affects the quality of the resulting biocomposite board. L. squarrosulus in 100% sugarcane bagasse media is the optimal type of white-rot fungus and the optimal composition of lignocellulosic material to manufacture mycelium-based biocomposite board.

Understorey plant is a type of basic vegetation under forest stands except for saplings. Understorey vegetation includes grasses, herbs, shrubs, and ferns. The presence of understorey vegetation can be used as an indicator of forest conditions and is expected to reduce disturbances to the forest. The purpose of this research is to determine the diversity and the dominance of understorey species under the pinewood stands based on pine ages in RPH Sempor, BKPH North Gombong. This research was conducted using a survey method and systematic sampling techniques at two different age groups pinewood forest of RPH Sempor, BKPH North Gombong. The result showed that the total understorey species found were 34 species from 21 families. The understorey species number found at the 25 years of pine forest was 22 species found and at the 45 years, there were 17 species. Based on the research that has been done, it can be concluded that the younger the age of pine stand, the more understorey species number. Evenness of the understorey species at two different ages of pine stand in RPH Sempor is evenly distributed, so there are no dominant species. The physicochemical factors measurement result showed that the canopy cover affected the temperature and humidity level, thus affecting the number of understorey individuals and the species number in each stand.
