Authors: Li Liu , Xiangyun Sun
Published: March 2023

Based on the effective teaching of primary school English class, this paper starts from studying the application of emotion attitude goal in class, and relies on the human-oriented version of primary school English textbook to discuss how primary school English teachers adopt effective teaching strategies to organize and implement English teaching activities, so as to achieve the goal of “emotion attitude and values” in English teaching. This paper explains the significance of realizing “emotion, attitude and value” in primary school English classroom and how to excavate emotion elements in English textbooks so as to effectively realize the three-dimensional goal of primary school English teaching. By studying the current status of primary school English teaching and existing problems, this paper points out that teachers should update their teaching concepts in time, and discuss and explore the aspects of lesson preparation, class, teaching test evaluation and so on around the theory of “unit integrated design”, so as to improve the efficiency of class and promote students’ emotions, attitudes and values while grasping knowledge. At the same time, the author emphasizes classroom practice, timely reflection after class and timely adjustment of the taught content so as to achieve the ultimate goal of “emotion, attitude and values”.

Authors: Kumar Pawan , Singh Ajit , Gupta Rahul , Khan Mohd Zaheen
Published: March 2023

Abstract: Management of solid waste is the major concern globally due to increasing quantities of waste materials and byproducts from industries. Lack of space availability for land filling and because of its increasing cost, utilization and recycling of industrial by- products and waste materials has the only option as it is economical and eco friendly. There are several types of such materials, which can be recycled or reused in construction. The utilization of such materials in construction not only makes it economical, but also helps in reducing disposal problems. One such material is wood ash (WA). Wood ash (WA) is the residue generated due to combustion or incineration of wood and wood products (chips, saw dust, bark, etc.).The XRD (X-RAY DIFFRACTION) test results, SEM (scanning electron microscope) analysis and chemical analysis of WA showed that it contains amorphous silica and thus can be used as cement replacing material. Many researches had been carried out to incorporate wood waste ash as a cement replacement material in the production of greener construction material (concrete/mortar) and also as a sustainable means of disposal for wood waste ash. Results of these researches indicated that wood waste ash can be effectively used as a cement replacement material for the production of structural concrete/mortar of acceptable strength and durability parameters.
About the Author of the Book “Abkhazia and the New Athos Monastery of St. Simon the Canaanite in it”
Authors:   Moscow Theological Academy, Solodov Nikolai V.
Published: March 2023

The article is devoted to establishing the authorship of the book “Abkhazia and the New Athos Monastery of St. Simon the Canaanite in it,” published in 1898 and signed with the initials “I. N.” The book is a significantly expanded reprint of the work under the same name by Archimandrite Leonid (Kavelin), published in 1885. The special literature contains various assumptions regarding the author-compiler whose name is hidden behind the initials. The analysis of the text of the book, the official reporting of the Society for the Restoration of Orthodox Christianity in the Caucasus and archival documents permit to establish that the book was compiled by retired colonel Ivan Alekseevich Nikiforov. The surviving letters of I. A. Nikiforov to Archimandrite Leonid (Kavelin) allow us to get an idea of the moral character of the author.
“Dear Friend... Do not be Angry for Frankness!”: Correspondence of L. N. Tolstoy and B. N. Chicherin
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Andreeva Valeria G.
Published: March 2023

The author of the article analyzes the correspondence between Tolstoy and Chicherin, describes the relationship of the correspondents, explains the problem of the worldview clash between two prominent figures of Russian cultural and public life in the second half of the 19th century. A careful study of the letters in their chronological order makes it possible to follow the development of the dialogue and polemics between Tolstoy and Chicherin, to understand the inner motives that moved each of them. According to the author of the article, the correspondents were most divided by their polar views on the role and importance of the state, law, morality and religion in the life of society and man. In addition, one of the reasons for the gradual cooling off between Tolstoy and Chicherin was the ardent desire of both to realize their own mission of spiritual mentoring: both Tolstoy and Chicherin wanted to become “teachers of mankind.”
Old Believer’s Book Culture in P. I. Melnikov-Pechersky’s Novel “In the Woods” (To the 140th Anniversary of the Writer’s Death)
Authors:   Nizhnevartovsk State University, Bytko Sergey S.
Published: March 2023

The article examines the peculiarities of P. I. Melnikov-Pechersky’s perception of the Volga Old Believers’ book tradition. In particular, it establishes the sources of the formation of the writer’s ideas about the role of bookishness in the daily life of “dissenters.” The author of “In the Woods” acquired a deep acquaintance with church literature during the performance of his official duties and numerous business trips. The article clarifies curious details of Melnikov’s description of the reading culture of the Old Believers, as well as the main ways of spreading bookishness among the “zealots of ancient piety.” The writer demonstrated his own view on factors that determined the popularity of a particular work among “dissenters.” The article examines Melnikov-Pechersky’s perception of the significance of the monasteries in the preservation of the Old Russian Cyrillic heritage, as well as the role of the scribes in the organization of the religious and everyday life of the Old Believers communities. The author analyzes the influence of the spread of the civil press and secular education on the processes of gradual secularization of the Old Believers community. Summing up the results, it can be concluded that Melnikov had very ambiguous attitude to the book traditions of the “old time lovers.” Thus, the author points to the extreme fanaticism of some polemical Old Believers’ writings, which destructively affect the consciousness of their readers, calling for moving away from progress and hating everything around them.

On the role of antibody affinity in the IgE mediated allergic response
Authors: Vogel Monique , Bachmann Martin , Mohsen Mona O. , Kramer Matthias , Starchenka Sviatlana , Whitehead Piers , Heath Matthew
Published: March 2023

Type I hypersensitivity, also known as classical allergy, is mediated
via allergen-specific IgE antibodies bound to type I FcR (FcεRI) on the
surface of mast cells and basophils upon cross-linking by allergens.
This IgE-mediated cellular activation may be blocked by
allergen-specific IgG through multiple mechanisms, including direct
neutralization of the allergen or engagement of the inhibitory receptor
FcγRIIb which blocks IgE signal transduction. In addition, co-engagement
of FceRI and FcγRIIb by IgE-IgG-allergen immune-complexes causes
down-regulation of receptor bound IgE, resulting in desensitization of
the cells. Both, activation of FceRI by allergen-specific IgE and
engagement of FcγRIIb by allergen-specific IgG are driven by
allergen-binding. Here we delineate the distinct roles of antibody
affinity versus avidity in driving these processes and discuss the role
of IgG subclasses in inhibiting basophil and mast cell activation.

Published: March 2023

Haemorrhagic stroke (HS) is a devastating form of stroke with a high
fatality rate. The lack of rapid lesion detection limits early diagnosis
of HS. Several susceptibility genes of HS found in genome-wide
association studies (GWAS) warrant transcriptional-level biomarkers for
useful utility. 13 GWAS level loci with minor allele frequency ≥ 0.05
were selected out of 95 loci related to HS. After validation, the mRNA
expression in peripheral leukocytes of 11 genes (PMF1, SLC25A44,
CASZ1, NINJ2, WNK1, DYRK1A, LRCH1, LDLR, SMARCA4, AQP9, and
LIPC) were measured in the HS case-control study (64 HS cases vs.
128 controls), and then verified in an ischemic stroke (IS) case-control
study (67 IS cases vs. 61 controls). LIPC (P=0.002) and
CASZ1 (P=0.040) were downregulated in HS patients, while
SLC25A44 was upregulated (P=0.009). In the IS case-control
study, the differential expression of LIPC (P=0.034) and
SLC25A44 (P<0.001) was observed. Although
CASZ1 expression was not different between IS cases and controls
(P=0.419) with fold change (FC) of 1.205, the direction of
expression was opposite to that in HS case-control study (FC=0.747). The
ROCtrfgs of traditional risk factors and gene score which was estimated
by combining LIPC, CASZ1, and SLC25A44 expression weights,
improved the utility for HS identification by 14.1% compared with
ROC (P=0.001). Expression of LIPC,
CASZ1, and SLC25A44 could serve as potential biomarkers for
identifying HS. CASZ1 might be a cause-specific indicator for
differentiating HS from IS. Transcriptional score of these three genes
could improve performance of the traditional risk model for HS
identification.
Femtosecond Optical Kerr Gate in Tissues
Authors: Meyer Henry J. , Mamani Sandra , Alfano Robert
Published: March 2023

The Optical Kerr Effect was investigated for the first time in
biological tissues. This nonlinear optical effect was explored in both
human brain and avian breast tissues using a time-resolved femtosecond
pump-probe Optical Kerr Gate. The Optical Kerr Effect describes the
nonlinear change in a material’s refractive index in response to an
electric field. It is fundamental to spectral effects that are commonly
used in biological science. The tested tissues produced a unique
ultrafast (700-800 fs) doubled peaked Kerr signal, which is indicative
of temporal interplay between the different components (electronic
plasma, and molecular) that make up the Kerr index. Temporal properties
varied between samples suggesting that this method could be used as a
new diagnostic. Understanding this Kerr behavior can help improve
current spectral diagnostic techniques, such as SRS, and potentially
create a new Kerr based biopsy method for the detection of diseased
tissues, such as cancer and Alzheimer’s.
The Ogres Zilie kalni park urban forest management
Authors: Kraukle Ieva , Stokmane Ilze , Vugule Kristine
Published: March 2023

The impact of the Covid-19 pandemic demonstrated the importance of urban forests for human well-being at a time of tight constraints, when large forests close to urban areas were in high demand. Increased use affects the management of territories. Urban forests play an important role in providing ecosystem services. Urban forests show a close link between ecosystem services and forest functions. A literature review was carried out, exploring the ecosystem services and specific urban forest services provided by such territories. This article examines the experience of the Ogres Zilie kalni during the Covid-19 pandemic, taking into account the peculiar functions of urban forests. Different types of recreation that take place in the Ogres Zilie kalni, and their impact on park management are discussed. The aim of the article is to analyse and present the challenges of urban forest governance and management under the influence of Covid-19, looking through the functions of urban forests. Taking into account the classifications of ecosystem services available in Zilie kalni, zoning and assessment of the territory have been carried out. Cartographic material has been created based on practical experience and employee interviews.
The practical experience of territory management gained during Covid-19 is important and should be taken into account in the future development of green spaces, respecting the new habits of visitors potentially affected by the pandemic, where one of the most important proposals is to develop more small localised recreation areas on smaller paths.

A large class in Köthe-Toeplitz duals of generalized Cesàro difference sequence spaces with fixed point property for nonexpansive mappings
Authors: Nezir Veysel , Dutta Hemen , Yıldırım Selçuk
Published: March 2023

In 1970, Ces?ro sequence spaces was introduced by Shiue. In 1981, K?zmaz
defined difference sequence spaces for ??, c0 and c. Then, in 1983, Orhan
introduced Ces?ro difference sequence spaces. Both works used difference
operator and investigated K?the-Toeplitz duals for the new Banach spaces
they introduced. Later, various authors generalized these new spaces,
especially the one introduced by Orhan. In this study, first we discuss the
fixed point property for these spaces. Then, we recall that Goebel and
Kuczumow showed that there exists a very large class of closed, bounded,
convex subsets in Banach space of absolutely summable scalar sequences, ?1
with fixed point property for nonexpansive mappings. So we consider a Goebel
and Kuczumow analogue result for a K?the-Toeplitz dual of a generalized
Ces?ro difference sequence space. We show that there exists a large class
of closed, bounded and convex subsets of these spaces with fixed point
property for nonexpansive mappings.

Published: March 2023

In this paper, we consider the ruin probability of risk models with a
geometric distribution of claim sizes. Since their probabilities can?t be
calculated directly, we use exponential distribution to estimate its upper
and lower bounds and asymptotic estimates based on the relationship between
geometric distribution and exponential distribution. Finally, some numerical
simulations are given to prove the superiority of our estimates.

The prevalence of depression among language learners, specifically Arabic learners, should receive proper attention from academics. Unfortunately, it would be easily overlooked by scholars because they were tend more focusing on the development of effective teaching strategy. The objective of current study was to investigate the effect of demographic variables and language proficiency on symptoms of depression in individuals learning Arabic as a second language. This cross-sectional study involved 1126 participants who voluntarily provided their consent. Of the participants, 762 were female and 364 were male (age M = 20.03 and SD = 1.56). The study collected demographic information, assess language acquisition levels, and measure symptoms of depression. Data was analyzed using descriptive statistics, Pearson correlation, and multiple linear regression. Results showed that model proposed in this study with its predictors explained 7.5% of the variance in depression symptoms while factors such as sex, number of siblings, living arrangement, listening skills, and reading skills were found being significant predictors in the model. This study highlights the prevalence of depression among individuals learning Arabic as a second language and the importance of demographic variables and language proficiency in predicting depression symptoms. The findings suggest that interventions to address depression in this population should take into account factors such as sex, number of siblings, living arrangement, and language skills.

Authors: Khadafie Muammar
Published: March 2023

This article describes the construction of Islamic Religious Education (PAI) during the Covid-19 pandemic. Restrictions on community activities to break the Covid-19 chain have fundamentally changed the education system in Indonesia. The implementation of learning that was originally carried out face-to-face is now carried out online or virtually. With this change in learning, PAI must adapt to the change itself, so that the purpose of education is to create students who believe and fear God Almighty who have a noble character, are healthy, knowledgeable, capable, creative, independent, and become democratic citizens. and responsibility can be realized. Using the Study Literature Review research method or library research, this article describes the construction of education in the era of the Covid-19 pandemic. The theories and concepts used are learning methods in the Covid-19 era. During the pandemic, learning models and methods in Indonesia generally use Blended Learning and e-Learning. The use of these two learning models is inseparable from the dynamics of government policies related to handling Covid-19. The results of the research found that the learning model that has the potential to be reconstructed in PAI is the blended learning method or model. The blended learning method is used to describe the problems of e-Learning, namely the problem of teachers and the limitations of the internet network. The Blended Learning model is a combination of offline learning methods (face-to-face, etc.) with online learning methods (e-learning).

Published: March 2023

The administrative duties performed by the deputy principals tend to obscure their academic responsibilities. The purpose of this study was to explore the deputy principals’ disciplinary role in enhancing students’ academic performance in secondary schools, in Bungoma South Sub-County, Kenya. A student’s academic performance is the sum of all curriculum implementation achievements as depicted from formative, continuous and summative evaluations, both internal and external. This study was necessitated by the need for an elaborate framework that could recognize the disciplinary functions of the deputy principal’s office in secondary schools that occasion academic success. The study was grounded on Hargreaves’ Capital Theory of School Effectiveness and Improvement of 2001. From the findings, there was an equivalent 79.55% agreement with suggested academic performance enhancement indicators. The Pearson’s correlational coefficients between the independent variables and the dependent variable ranged between 0.005 at 0.01 confidence level and 0.023 to 0.029 at 0.05 confidence level. This implied that a significant correlation between students’ academic performance and the disciplinary role of deputy principals in secondary schools in the Bungoma South sub-county was found to exist. The findings of the study have implications for policy, research, and practice.
An Investigation into Difficulties in Listening Comprehension Encountered by English-Majored Freshmen at Dong Nai Technology University and Recommendations
Authors: Phan Lam , Nguyen Duyen
Published: March 2023

Listening is one of the crucial skills in learning English as well as communicating in daily life. As we know listening to a message is not as simple as hearing it, the listener must comprehend the message and respond properly. In Vietnam, from primary schools to high schools, many of them place more emphasis on grammar, reading and vocabulary rather than speaking and listening. Students do not have many chances to practice listening in class and outside class as well. As a result, many English majors have problems in listening comprehension, especially freshmen who lack experience and do not have suitable learning methods. Thus, this paper aims to investigate difficulties in listening comprehension faced by students as well reasons of these difficulties. Both qualitative and quantitative methods were employed in the study to collect data. The study results reveal the difficulties and causes which are related to listening materials, listeners, and facilities. It is recommended that students should be exposed to a wider range of listening techniques and applying listening strategies. In addition, teachers play a crucial role in determining the listening techniques to use and how to adapt them in order to help students overcome the listening challenge.

Indonesia merupakan zona “ring of fire” karena letak geografisnya berada di antara pertemuan tiga lempeng tektonik besar yaitu lempeng Pasifik, Indo-Australia, dan Eurasia. Ketiga lempeng tersebut menyebabkan indonesia memiliki banyak gunung berapi yang masih aktif diseluruh dunia, sehingga tumbukan antar lempeng tersebut dapat mengakibatkan gempa di wilayah tertentu. Salah satu wilayah Indonesia yang memiliki potensi rawan gempa bumi yaitu provinsi Nusa Tenggara Barat. Hal tersebut tedapat risiko gempa yang cukup tinggi akibat subduksi Lempeng Indo-Australia di selatan Pulau Lombok dan Busur Belakang Flores di utara. Penelitian ini menggunakan metode empiris dengan persamaan Ground Motion Prediction Equation (GMPE) Donovan yang telah dilakukan untuk memetakan daerah yang rawan terhadap gempa bumi di Wilayah NTB. Tujuan dari penelitian ini adalah untuk memetakan percepatan tanah maksimum atau Peak Ground Acceleration (PGA) dan intensitas seismik di dalam dan sekitar kawasan Nusa Tenggara Barat. Berdasarkan hasil dari perhitungan yang telah didapatkan nilai percepatan tanah maksimum (PGA) pada wilayah Nusa Tenggara Barat dengan menggunakan metode empiris persamaan donovan yaitu sebesar 7.23g  204.39g. Berdasarkan nilai PGA yang telah diperoleh, metode donovan menghasilkan nilai PGA yang hampir mirip pada peta acuan Pusat Studi Gempa 2017.  Dalam hal ini dapat dilihat bahwa metode donovan merupakan metode yang sesuai untuk mendapatkan nilai PGA pada wilayah NTB.Kata Kunci: PGA, Donovan, NTB, Magnitudo

While literature on graduate education in Western countries has long regarded the advising relationship as critical for student development and success, far less attention has been paid to graduate advising relationship in the context of South Korea. Using a latent profile analysis approach, the present study examines the ways in which Korean graduate students (N=307) are classified based on the types of support provided by their advisors and how such classification is related to student outcomes such as graduate satisfaction and perceived academic achievement. Results reveal three distinct latent profiles among students: “overall balanced high support,” “moderate academic support,” and “low academic support.” Findings also indicate that students in the “overall balanced high support” profile had significantly higher levels of graduate satisfaction and achievement compared to students in the other two profiles. Significant difference was not found in either outcome between students in the “moderate academic support” and “low academic support” profiles. These findings provide initial evidence of heterogeneity across graduate students in terms of advisor support and related outcomes in the Korean context. Implications for research and practice are then discussed.

Type two diabetes has become a civilization disease in the recent years, and the accompanying obesity, metabolic syndrome and non-alcoholic fatty liver are often the inseparable components of the clinical presentation in patients with diabetes of this type. The treatment of each of these elements is important for optimal metabolic control of the patients, as well as directly affecting their life expectancy. However, The ideal solution would be to take as few drugs as possible, preferably drugs that have a beneficial effect on several coexisting diseases at the same time. In the recent years, there have been more and more reports about the pleiotropic effect of drugs affecting the incretin axis - GLP-1 analogues. The presented paper provides an overview of the latest knowledge on the effect of GLP-1 receptor agonists on weight reduction and reduction of changes in the course of non-alcoholic fatty liver disease.

Purpose: Comparative analysis of the decision-making process of family farmers who participate and do not participate in associations and cooperatives in the region of Mossoró – RN.
 
Theoretical framework: Family farming is a productive organization that coexists with the capitalist structure of production and has unique features, since the owner is also a worker, manages the means of production and does not primarily aim at financial profit, since production is intended to support the family and the property. The decision-making process escapes economic logic, as it also considers social, environmental, ethical and cultural aspects. Cooperatives and associations represent an alternative to the problems imposed by the market.
 
Method/design/approach: This is a quantitative-descriptive research. A total of 137 family farmers from the region of Mossoró – RN participated in the study. The questionnaire was organized with 5 questions about the centralization of decision-making used by family farmers in the region.
 
Results and conclusion: The decision-making of farmers in the management of their properties does not differ in terms of participation or non-participation in associations and cooperatives.
 
Research implications: Although associations and cooperatives present multiple responses to the problems arising from globalization, a significant portion of farmers do not participate in them, and this factor should be deepened to understand the non-participation of farmers in associations and cooperatives and their non-influence in the decision-making of those.
 
Originality/value: Studies of this nature lead to rethinking and improving the practices of decision-making, marketing and integration of subjects within the scope of family farming.

Background: Accurate diagnosis benefits patients and their families by directing clinical management; predicting recurrence risks; providing prognosis; and preventing the invasive, time-consuming, and costly diagnostic odyssey. The present study aimed at evaluating the usefulness and clinical utility of supplementary testing (deletion/duplication, targeted genome methylation analysis, and whole mitochondrial genome testing) after inconclusive or negative exome results and the outcome of the supplementary testing.
Methods: A total of 3,505 clinical exome sequencing results were evaluated, and cases with supplementary testing were analyzed for the accuracy and validity of the supplementary testing.
Results: The present study cohort comprised 26 cases where supplementary testing was ordered (12 inconclusive results and 14 negative results). Out of the 12 inconclusive results, only one case was positive for supplementary testing (1/12) and none of the negative cases (0/14).
Conclusion: For most cases, supplementary testing to negative exome sequencing failed to identify any possible explanation of the disorder, concluding that supplementary testing has limited clinical utility.

Published: March 2023

Bu çalışma, silolama öncesi aktifleştirilen Lactobacillus buchneri (NCIMB 40788 ˗ CNCM I-4323; Lalsil AS, Lallemand Inc., Canada) inokulantının mısır silajına üre ile ilavesinin fermantasyon ve aerobik stabilite üzerine etkilerini belirlemek amacıyla düzenlenmiştir. Mısır süt olum döneminde hasat edilmiştir. Hasat sonrası materyaller, 6 muamele grubuna bölünmüştür. Muamele grupları 1- Kontrol; 2- Lactobacillus buchneri (LB), 3×108 kob/g taze materyal; 3- Üre (Üre), %1 kuru madde; 4- Lactobacillus buchneri + Üre (LB+Üre); 5-Aktive edilen Lactobacillus buchneri (aLB), 3×108 kob/g taze materyal; 6- Aktive edilen Lactobacillus buchneri + Üre (aLB+Üre)’den oluşmaktadır. Katkı maddesi ilavesinden sonra silaj örnekleri her muamele grubunda 3’er tekerrür olmak üzere plastik torbalara vakumlanarak doldurulmuştur. Fermantasyonun 1., 3., 7., 14. ve 75. günü açılan silaj örneklerinde kimyasal ve mikrobiyolojik analizler yapılmıştır. Yetmiş beşinci gün açılan silajlara 7 gün süre ile aerobik stabilite testi uygulanmıştır. Bu çalışmada silolama öncesi aktifleştirilen Lactobacillus buchneri inokulantı ve üre ilavesi mısır silajlarının fermantasyonun ve aerobik stabilitesini olumlu yönde etkilemiştir. aLB grubundaki silajların ham protein (HP), laktik asit (LA) değerleri artarken, asetik asit (AA), propiyonik asit (PA), pH, nötral çözücülerde çözünmeyen lif (NDF), asit çözücülerde çözünmeyen lif (ADF), hemiselüloz (HSEL) ve maya içerikleri ise düşmüştür. Silajlara aLB+ Üre ilave edilmesi silajların aerobik stabilitelerinin gelişmesini sağlamıştır. Sonuç olarak aktifleştirilen Lactobacillus buchneri ve ürenin birlikte kullanılması mısırın fermantasyon profili, kimyasal bileşimini ve aerobik stabilitesini iyileştirebilir.

Bu çalışma tütün üretim ve pazarlama kooperatiflerin sayıca fazla kurulduğu Adıyaman-Çelikhan’da yapılmıştır. Bu çalışmada, tütün üretim ve pazarlama kooperatiflerine üye olan ve üye olmayan üreticilerin sosyo-ekonomik özellikleri, işletme özellikleri ve tütün üretim ve pazarlama kooperatiflerinin geliştirilmesi ve yaygınlaştırılmasına katkıda bulunmak amacıyla, aynı köyde yaşayan kooperatife üye olan ve üye olmayan tütün üretimi yapan toplam 90 üretici oransal örnekleme yöntemi kullanılarak belirlenmiş ve yüz yüze anket çalışması yapılmıştır. Elde edilen sonuçlara göre; kooperatife üye olan üreticilerin; daha fazla sözleşme yaptıkları, daha fazla çiftçi kayıt sistemine dahil oldukları, sarmalık kıyılmış tütün mamullerinden alınan ÖTV oranını daha fazla bildikleri, ortak olma nedenlerinde “ürünleri yüksek fiyata satabilmenin ilk sırada yer aldığı”,  kooperatifin en önemli fonksiyonunun ürün alımı olduğunu, kooperatifçilik konusunda eğitime ihtiyaç duydukları, teknik veya hukuki konularda ziraat odasından daha fazla bilgi aldıkları kooperatife üye olmayan üreticilerin ise, başka ürün yetiştirmeyi bilmedikleri için tütün üretimi yaptıklarını, kooperatiflerin daha iyi ve başarılı olması için devletin finansal yardım yapması gerektiğini, kooperatife üye olmak istememelerinin başlıca sebepleri arasında; mevcut kooperatifleri güvenilir olarak bulmadıklarını, başarılı olamayacaklarını belirtip, ancak bu sorunların çözülmesi halinde %83,8’i üye olabileceklerini ifade etmişlerdir. Kooperatif yöneticileri ve üyelerine hak ve yükümlülükleri ile kooperatif ve işletmecilik konularında belli periyodlarla eğitim faaliyetlerinin yürütülmesi kooperatifçiliğin devamlılığını sağlamaya katkı sağlayacaktır.
