Authors: Kaya Selman , Pınar Salih
Published: August 2022

Background and Study Aim: This study aims to examine the effects of the Triphasic Training Model (TTM) applied with different set designs (15-30 sec intra-set) on reactive strength index (RSI) and vertical jump values. Material and Methods:. Sixteen male athletes over 18 with at least three years of strength training experience (2 days a week) actively engaged in sports participated in the study. The study group was divided into two groups by calculating the relative strengths. The 15-second cluster set (C15) group exercises were performed with 15 seconds of rest between repetitions, and the 30-second cluster-set (C30) group practiced the exercises with 30 seconds of rest between repetitions. The triphasic training model was applied to all study groups for six weeks. Countermovement jump (CMJ) and drop jump tests were performed on the athletes before and after the training. Optojump brand photocell system was used for CMJ and RSI tests. For the RSI test, the desk height was determined as 40cm. Kolmogorov-Smirnov values were examined to assess the homogeneity of the data. To compare the means between groups, ANOVA was used for Repeated Measures, and a t-test was used to compare the pretest-posttest mean of the groups. The statistical significance level was determined as p<0.05. Results: After triphasic training, CMJ and RSI values of both C15 and C30 groups increased (p<0.05). When the within-group pretest-posttest values were examined, it was seen that the C30 group showed more improvement than the C15 group. Conclusions: As a result, it was seen that the triphasic training model applied twice a week for six weeks improved the CMJ and RSI values of the athletes, and it was more effective to use C30 instead of C15 in the use of cluster sets.

Published: August 2022

Background and Study Purpose. Body stability is an important factor in the manifestation of human motor skills. The purpose of the research is to evaluate the efficiency of balance exercises, applied for 28 weeks, with a frequency of one activity / week, on a group of undergraduate students of the “Dunărea de Jos” University of Galați. Material and Methods. 195 subjects participated (99 males and 96 females), divided for analysis into 3 groups (underweight, N = 21, age = 20.16 ± .38, BMI = 17.46 ± .20); (normal weight, N = 111, age = 20.30 ± .21, BMI = 21.70 ± .17); (overweight / obese, N = 63, age = 19.90 ± .18, BMI = 30.69 ± .61). The tests were applied at 3 distinct times: initial T1 at the beginning of the academic year, intermediate T2 towards the end of semester 1 and final T3 at the end of semester 2. 3 static balance assessment tests were used (One leg standing test with closed eyes, Stork test and Flamingo test), respectively 4 tests to evaluate the dynamic balance (Bass test, Functional reach test, Walk and turn field sobriety test and Fukuda test). Results. ANOVA with repeated measurements and the differences between the test moments highlight in most cases values ​​of F associated with significant thresholds (p <0.05), so there is an improvement in results for all 3 groups. The differences between T1 and T2 tests are larger than those between T2 and T3, so for almost all tests the progress is higher in the first semester, and in semester 2 there is a slight reduction, as a result of adapting to the proposed exercises. Even if they progress significantly, the group of overweight people has obviously weaker average results than normal weight and underweight people, signaling numerous individual cases that have problems in maintaining static balance and commit errors in dynamic balance tests. The better performances of the underweight in 3 cases (One leg standing test, Flamingo test Fukuda test and Walk and turn field sobriety test) cannot be generalized due to their small number compared to the other 2 groups, and this aspect can be considered as a new direction of investigation. Conclusions. There are premises for a favorable evolution of the balance indices for the group tested in this age group, but it must be taken into account that the low initial fitness level (generated by the lack of concerns for a lifestyle based on physical activities) is a factor that facilitated these less spectacular advances, but still statistically significant.
Crack length estimations for small-scale fracture experiments via image processing techniques
Authors: Schmuck K. , Alfreider M. , Kiener D.
Published: August 2022

Accurate knowledge of the current crack length is crucial to evaluate fracture mechanical tests. At the sub-micron to micron scale, the crack length is directly accessible via observation during in-situ experiments in electron microscopes, or indirectly via calculation from sample stiffness. In the current work, image processing techniques were used to introduce a semi-automatic technique to measure crack lengths at the micron scale from image sequences. The technique utilizes manually defined filters and searches for contours near the previous crack tip locating the new one according to the previous position. To demonstrate validity and capability, three micron-sized notched cantilevers were prepared for bending experiments and tested in-situ by partial unloading. Comparison of crack lengths determined by the proposed method, manual measurement and sample stiffness revealed a reasonable agreement, while occasional deviations allow further insights into the crack behaviour. Thus, our new approach enables more in-depth investigation of small-scale fracture processes.

The study was a cross sectional survey of selected public procuring entities in Harare. These included the Ministry of Health, Ministry of Agriculture, Ministry of Transport, Ministry of Finance and Ministry of Economic Development. A total of 132 respondents took part in the study. The findings revealed that the government departments under study lacked supply chain management planning that is well synchronized with the respective ministries’ overall strategic planning. Inconsistencies were identified between the departments’ supply chain structure and information systems that had been implemented and it had become difficult to incorporate real-time information sharing into supply chain operations.
THE ARM’S LENGTH PRINCIPLE: A PANACEA OR PROBLEM TO REGULATING TRANSFER PRICING TRANSACTIONS BY MNES IN DEVELOPING COUNTRIES
Authors:   University of Johannesburg, South Africa, Mpofu Favourate Y. , Wealth Eukeria ,   University of Namibia, South Africa
Published: August 2022

Transfer pricing manipulation by multinational enterprises is a big problem in developing countries, considering the increased levels of tax avoidance and evasion in these countries. The revenue lost through evasion and avoidance schemes as well as through aggressive tax planning robs developing countries of the much-needed domestic revenues to fund public expenditure. The repercussions of revenue inadequacies are evident in developing countries’ governments to adequately invest in education, tax administration, health and security, infrastructural development, and economic development. Most developing countries having enacted transfer pricing regulation, with the arm’s length principle are at the core of these regulations. This principle has been criticized in literature for its inefficiency and ineffectiveness in regulating transfer pricing in evolving economic times, while some researchers continue to maintain its relevance. In view of the conflicting views on the cogency of the arm’s length principle in developing countries, this paper sought to unpack this debate through an evaluative review to show the areas of disagreement and agreement among scholars. The review was motivated by the continued concern and discussions of tax evasion and avoidance by multinational enterprises through aggressive transfer pricing in developing countries. Through a critical literature review, this article assesses the applicability and relevance of the principle in developing countries. Findings reveal controversies in the availability of comparable data, continued abuse of transfer pricing as well as the difficulty in applying the principle in digital transactions and intangibles.

The aim of this study was to produce high yield of a local bacterial alkaline protease in the yeast system because the scientific involvement of microorganisms in enzyme production is still not given enough attention in Saudi Arabia. Soil samples were collected from the rhizosphere of some desert plants in Saudi Arabia. Ninety-three alkaline protease producing bacterial isolates were recovered on skimmed-milk agar at pH 9.4 and 45°C for 48 hr. Isolate D9 obtained from the rhizosphere of Heliotropium digynum at Dhahran City was the most potent isolate in respect to enzyme productivity (184.6 U/ml). The full gene of alkaline protease was amplified and showed the expected size (1300 bp). Restriction enzymes analysis also verified the integrity of the PCR product. The sequence of the protease gene revealed an open reading frame of 1329 nt correspond to the full length of the protease gene of isolate D9 encoding a 443 aa protein. After ligation of the amplified gene by the TA cloning method, digestion with appropriate restriction enzymes confirmed the integrity of the cloned gene. The insert was prepared by two PCRs that were conducted with a pair of primers specifically designed for this purpose. The digested and purified cloning vector pRS426/GAL1p-207-Glu-MS was ligated with the insert then transformed into various strains of Saccharomyces cerevisiae via the electroporation method. Maximum protease expression was done by recombinant OS303 in galactose containing media (145.5 U/ml) with an approximately 2-fold increase when compared with the wild OS303 strain., this may be due to ability to activate gal operon.

Authors: Semary N. A. El
Published: August 2022

To investigate the best carbon source for mixotrophic growth of Cyanothece sp. This cyanobacterium is also used as a source of biogenic silver nanoparticles. The study also investigates the antimicrobial activity of nanoparticles (both gold and silver) biosynthesized by this cyanobacterium. Those particles are tested solely and in combination as antimicrobial agents against two farm bacteria commonly found in Al Ahsa. Soil extract was prepared from pesticide-free soil whereas dextrose was prepared in 6 mM concentration and the cyanobacterial culture cell density was determined after two weeks. Cultures of Cyanothece sp. were incubated with silver nitrate until turning brown. The external solution of culture was analyzed using chemical analyses including UV- visible and FTIR to confirm nano silver formation. Previously-biosynthesized nano gold particles by Cyanothece sp. were used solely and in combination with newly biosynthesized nano silver particles for antimicrobial bioassay against the two farm bacterial pathogens. The best mixotrophic cyanobacterial growth was obtained for soil extract followed by dextrose which were significantly different from control. The synthesis of nanoparticles using this cyanobacterium was confirmed using UV-visible light spectrophotometry which detected the characteristic surface plasmon resonance peak in the range of 410-450 nm and the FTIR spectroscopy which showed the characteristic silver nanoparticles peak at 3.297 cm-1 which overlaps with -OH- in addition to the other functional groups associated with nano silver particles detected at 2,927, 1,631 and 1,383 cm−1. Silver nanoparticles showed the strong antimicrobial effect against both pathogens Staphylococcus aureus (MRSA) and Staphylococcus warneri with inhibition zone diameter 1.3 cm for both followed by the combination of silver and gold nanoparticles. Soil extract is a natural medium rich in all types of organic and inorganic nutrients which enhance algal mixotrophic growth. Biosynthesized silver nanoparticles showed the strongest antibacterial action against both pathogens most likely due to its ease of penetration, interaction with cellular components, generation of reactive oxygen species and induction of oxidative stress leading to bacterial death.

Published: August 2022

A preparação para o enfrentamento de situações dilemáticas no relacionamento com alunos, colegas e instituições é fundamental para o pleno exercício da atividade docente. A presente pesquisa teve como objetivo analisar percepções e opiniões coletadas sobre a existência de um código de ética para a profissão docente entre formadores de professores, professores da educação básica e licenciandos. Os dados foram obtidos a partir de formulário digital, divulgado entre os grupos mencionados. A análise indicou a necessidade da existência de um instrumento que oriente as ações de professores frente a situações espinhosas, não discutidas nos cursos de formação e que fazem parte do cotidiano escolar. Por outro lado, há preocupação sobre quem elaboraria esse instrumento e como seria utilizado pelas instituições. Os resultados também apontam para a demanda de licenciandos, professores e formadores de professores por processos formativos que privilegiem aspectos da orientação, reflexão e tomada de decisões em situações do cotidiano escolar. A inclusão desses temas nos cursos de formação de professores faz-se essencial para que possam participar ativamente da contínua construção de um possível código de ética, ou de práticas de reflexão sobre os princípios e valores que norteiam sua profissão. Defendemos que é fundamental a presença do tema “código de ética” nos currículos de formação de professores, pois os formandos deveriam ser prevenidos de que as suas futuras atribuições no cotidiano laboral não se limitam ao ensino, mas envolvem também, responsabilidades decorrentes das questões que surgem nesse contexto e do impacto de suas decisões sobre estudantes, docentes e instituições.
EMOTION REGULATION IN THE WORKPLACE: A QUALITATIVE STUDY WITH TEACHERS
Authors: Morais Franciane Andrade de , Gondim Sônia Maria Guedes , Palma Emanuel Missias Silva
Published: August 2022

This study aimed to characterize the emotional labor of the professional andtechnological education teacher by examining the emotions and the emotion regulation strategies adopted by teachers. Eight focus groups were held, with the participation of forty-one teachers in total, to collect the data. For the data analysis, we adopted the inductive and deductive categorization methods. The results showed that different emotions are activated in the face of specific emotional demands and that teachers use a variety of strategies, either in isolation or in chains, to regulate them. However, cognitive change strategies and situation modification of the procedural model of emotional regulation were more frequently reported. The results suggest differences in the regulatory preferences of the teachers based on the career period and the training /performance area. Future research could use varied methods (e.g., observation diary) to investigate regulation's dynamic and contextual process and its outcomes and propose a contextual scale of teacher emotional regulation. The findings have implications for teacher training programs, educational management, and future research.
Efficient Learning of Interpretable Classification Rules
Authors: Ghosh Bishwamittra , Malioutov Dmitry , Meel Kuldeep S.
Published: August 2022

Machine learning has become omnipresent with applications in various safety-critical domains such as medical, law, and transportation. In these domains, high-stake decisions provided by machine learning necessitate researchers to design interpretable models, where the prediction is understandable to a human. In interpretable machine learning, rule-based classifiers are particularly effective in representing the decision boundary through a set of rules comprising input features. Examples of such classifiers include decision trees, decision lists, and decision sets. The interpretability of rule-based classifiers is in general related to the size of the rules, where smaller rules are considered more interpretable. To learn such a classifier, the brute-force direct approach is to consider an optimization problem that tries to learn the smallest classification rule that has close to maximum accuracy. This optimization problem is computationally intractable due to its combinatorial nature and thus, the problem is not scalable in large datasets. To this end, in this paper we study the triangular relationship among the accuracy, interpretability, and scalability of learning rule-based classifiers.
The contribution of this paper is an interpretable learning framework IMLI, that is based on maximum satisfiability (MaxSAT) for synthesizing classification rules expressible in proposition logic. IMLI considers a joint objective function to optimize the accuracy and the interpretability of classification rules and learns an optimal rule by solving an appropriately designed MaxSAT query. Despite the progress of MaxSAT solving in the last decade, the straightforward MaxSAT-based solution cannot scale to practical classification datasets containing thousands to millions of samples. Therefore, we incorporate an efficient incremental learning technique inside the MaxSAT formulation by integrating mini-batch learning and iterative rule-learning. The resulting framework learns a classifier by iteratively covering the training data, wherein in each iteration, it solves a sequence of smaller MaxSAT queries corresponding to each mini-batch. In our experiments, IMLI achieves the best balance among prediction accuracy, interpretability, and scalability. For instance, IMLI attains a competitive prediction accuracy and interpretability w.r.t. existing interpretable classifiers and demonstrates impressive scalability on large datasets where both interpretable and non-interpretable classifiers fail. As an application, we deploy IMLI in learning popular interpretable classifiers such as decision lists and decision sets. The source code is available at https://github.com/meelgroup/mlic.
HLA-DQ Mismatches Lead to More Unacceptable Antigens, Greater Sensitization, and Increased Disparities in Repeat Transplant Candidates
Authors: Isaacson Dylan , Schold Jesse D. , Gmeiner Michael W. , Copley Hannah C. , Kosmoliaptsis Vasilis , Tambur Anat R.
Published: August 2022

Significance Statement

HLA-DQ donor-specific antibodies are associated with antibody-mediated rejection and renal graft loss in single-center studies. However, HLA-DQ remains largely unaccounted for in kidney allocation. US transplant registries do not include donor-specific antibody data, precluding direct analysis of HLA-DQ mismatches and transplant outcomes. The authors examined data from patients in the Scientific Registry of Transplant Recipients who were relisted after graft failure with unacceptable antigens corresponding to the HLA typing of their previous donor as a proxy for donor-specific antibodies. Mismatched HLA-DQ antigens were the most likely to be designated as unacceptable, especially in African American and Hispanic patients. Unacceptable HLA-DQ antigens precipitated sensitization greater than or equal to any other HLA locus. These findings underscore the immunogenicity of HLA-DQ mismatches, which ultimately serves as a barrier to transplantation.

Background

In single-center studies, HLA-DQ mismatches stimulate the most pathogenic donor-specific antibodies. However, because of limitations of transplant registries, this cannot be directly confirmed with registry-based analyses.

Methods

We evaluated patients in the Scientific Registry of Transplant Recipients who were relisted after renal graft failure with new, unacceptable antigens corresponding to the HLA typing of their previous donor (UA-PD) as a proxy for donor-specific antibodies. Linear regression was applied to estimate the effects of HLA mismatches on UA-PD and the effects of UA-PD on calculated panel reactive antibody (cPRA) values for 4867 kidney recipients from 2010 to 2021.

Results

Each additional HLA-DQ mismatch increased the probability of UA-PD by 25.2% among deceased donor transplant recipients and by 28.9% among living donor transplant recipients, significantly more than all other HLA loci (P<0.05). HLA-DQ UA-PD increased cPRA by 29.0% in living donor transplant recipients and by 23.5% in deceased donor transplant recipients, significantly more than all loci except for HLA-A in deceased donor transplant recipients (23.1%). African American deceased donor transplant recipients were significantly more likely than Hispanic and White recipients to develop HLA-DQ UA-PD; among living donor transplant recipients, African American or Hispanic recipients were significantly more likely to do so compared with White recipients. Models evaluating interactions between HLA-DR/DQ mismatches revealed largely independent effects of HLA-DQ mismatches on HLA-DQ UA-PD.

Conclusions

HLA-DQ mismatches had the strongest associations with UA-PD, an effect that was greatest in African American and Hispanic recipients. cPRA increases with HLA-DQ UA-PD were equivalent or larger than any other HLA locus. This suggests a need to consider the effects of HLA-DQ in kidney allocation.

Por que é importante revisitar o conceito de cultura e estudos culturais? Hoje encontramos em todos os lugares muitos significados de culturas falando no plural. A cultura está embaçada e seu estudo caiu em desordem epistemológica. O interesse deste artigo é oferecer um olhar crítico sobre os usos da cultura. A cultura não pode ser dissociada do estado-nação e isso acaba por ser uma instituição com uma trajetória complexa porque teve que primeiro confrontar, e depois negociar com a vitalidade das etnias. Etnia e cultura têm características compartilhadas, mas em oposição e significam diferentes campos de atuação. Para realizar esse olhar crítico, o artigo é dividido em três partes. O primeiro refere-se às indústrias culturais e artefatos cunhados pelas escolas de Frankfurt e da Grã-Bretanha; o segundo, ao surgimento de um novo paradigma baseado nas políticas de reconhecimento que os estados-nação iniciaram desde as últimas décadas do século XX; finalmente, visitaremos o conceito de identidades indispensáveis à abordagem das culturas nos estados-nação da era global.

Purpose: The purpose of this study was to investigate the longitudinal effects of health status on changes in the use of long-term care insurance for the elderly.Methods: The total subjects included 4,110 people aged 65 or over who responded to the 12th and 15th surveys of the Korea Welfare Panel Study. Frequency analysis, x2 test, correlation, and multinomial logistic regression were applied.Results: First, the group using the long-term care insurance system for the elderly was classified into ‘continue not using’ (88.8%), ‘new use’ (6.9%), ‘continued use’ (3.1%), and ‘discontinue use’ (1.2%). Second, examining the determinants of changes in the use of the elderly long-term care insurance system, when older adults were older, and when their depression was higher, it was highly possible for them to use the elderly long-term care insurance system. Also, the elderly in single households were more likely to belong to the ‘continuous non-use’ group.Conclusion: Older adults in the group of continuously using the elderly long-term care insurance system showed negative physical health status, mental health, and family relationship health compared to other groups. The elderly households composed of elderly couples were more likely to not use the elderly long-term care insurance system.

Método: Una muestra no probabilística de 151 estudiantes universitarios de quinto año o superior de su respectiva carrera universitaria respondió a medidas de salud mental (DASS-21), de bienestar subjetivo (satisfacción con la vida y felicidad subjetiva), y del nivel de endeudamiento asumido para financiar sus estudios universitarios. Los análisis incluyeron regresiones lineales múltiples jerárquicas donde se incluyeron como variables independientes la variable género en un primer paso y el endeudamiento por créditos universitarios en el segundo paso. En cada regresión se incluyó un factor de salud mental y de bienestar subjetivo como variable dependiente.

Resultados: Resultados indican que el endeudamiento por motivos de estudio predice significativamente satisfacción con la vida (F(2, 148) = 5,95, p = 0,003, R2 Adjusted = 0,06; β = -0,16, p = 0,049), pero no predice felicidad subjetiva (p = n.s.) (factores de bienestar subjetivo), sintomatología depresiva (p = n.s.), ansiosa (p = n.s.), ni estrés (p = n.s.) (factores de salud mental).

Conclusión: Resultados del estudio sugieren que los estudiantes universitarios pudieran percibir el endeudamiento estudiantil como una inversión hacia el futuro lo que pudiera operar como un factor protector de su salud mental y bienestar subjetivo.
A mathematical model for determining engineering soil classifications from pedological data
Authors: Fanourakis G C
Published: August 2022

Various pedological soil classification systems exist worldwide, including an internationally accepted system and various national systems, many of which have been incorporated into databases that include maps. Various physical and chemical soil properties are used for classifying soils according to these pedological systems. This paper proposes an approach which may be used to determine the engineering properties of soils from the physical and chemical properties that are used to pedologically classify soils by systems, and, in particular, the South African Binomial System. These engineering properties include the USCS and AASHTO classification groups which may, in turn, be used as a means of rapidly determining the general suitability of areas for proposed development, particularly during the reconnaissance investigation stages of transportation route locations and township developments, with a resultant saving of time and money. The model was verified using data from the study area, as well as from an area located approximately 190 km from the study area. A total of 88% of the classification groups determined by the model, in the study area, were correct. Furthermore, only 6% of the classifications were incorrect by a maximum of two groups. The classifications determined for the soils outside the study area were all correct.

Authors: Caro-Romero Felipe César Camilo
Published: August 2022

El artículo estudia el origen y la consolidación de la imagen del grupo los Felipitos como parte de la historia del movimiento de disidencia sexual y de género de Bogotá. Se analizan las fuentes usadas en investigaciones académicas y de difusión. Además, se hace un análisis del grupo en un contexto global, encontrando similitudes entre los Felipitos y el movimiento homofílico de la región. La consolidación del grupo como antecedente del movimiento de disidencia sexual y de género colombiano está ligado a la entrada del sector en las políticas públicas de Bogotá a inicios del siglo XXI. De esta manera se devela el contexto político detrás de la consolidación de una imagen del pasado.

Higrotermal yaşlandırma ile ahşap ve ahşap esaslı malzemelerin uzun süreli kullanım performansının belirlenebilmesi mümkündür. Bu çalışmada higrotermal yaşlandırmanın, MDF ve sunta levhalarda renk, yüzey pürüzlülüğü ve vida çekme direnci üzerine etkisi araştırılmıştır. Bu amaçla 50×50 mm boyutlarında hazırlanan test örnekleri, 2 hafta boyunca 65±5% bağıl nem ve 20±2 °C sıcaklıkta klimatize edilmiştir. Higrotermal yaşlandırma için numuneler saf su ile doldurulmuş 20 °C sıcaklıktaki su banyosunda 30 gün boyunca bekletilmiştir. Numunelerin renk ölçümleri ASTM-D 2244-2 standardına göre Konica Minolta marka spektrofotometre kullanılarak gerçekleştirilmiştir. Yüzey pürüzlülüğü testleri ISO 4287 standardına göre Tokyo Seimitsu Accretech Handysurf E-35 B iğne taramalı portatif yüzey ölçüm cihazı ile yapılmıştır. Vida çekme direnci testleri TS EN 13446 standardına uygun olarak gerçekleştirilmiştir. Test sonuçlarına göre higrotermal yaşlandırmanın vida çekme direncini düşürücü bir etkisi olduğu belirlenmiştir. Higrotermal yaşlandırma ile birlikte test örneklerinin kontrol örneklerine göre toplam renk değişimlerinin arttığı, anlaşılmıştır. Higrotermal yaşlandırma testine tabi tutulmuş MDF ve sunta levhaların kontrol örneklerine göre daha düşük vida çekme direncine sahip oldukları tespit edilmiştir.

Bu kadro pozisyonları işçilerin yevmiye ücretlerinin belirlenmesinde kullanılmaktadır. Ancak her bir kadro pozisyonu için işçilerin gerçekleştireceği işler ayrı ayrı tanımlanmamıştır. Çalışmada iş tanımı kavramı ve iş tanımının ormancılık faaliyetleri için önemi açıklanmış, daha sonra ormancılık araştırma enstitüsü müdürlükleri bünyesinde çalıştırılan hizmet vasıtası şoförü için içerik analizi ve gözlem tekniklerinden yararlanılarak örnek teşkil edebilecek bir iş tanımı hazırlanmıştır. Bu kapsamda, öncelikle ormancılıkta hizmet vasıtası şoförlerinin gerçekleştirdiği işler belirlenmiş ve daha sonra mevzuat taraması yapılmak suretiyle bir iş tanımı oluşturulmuştur. Bu iş tanımı, hizmet vasıtası şoförlerinin işe alım kriterlerinin belirlenmesi, görevlerinin, çalışma koşullarının ve sorumluluklarının açıklanmasında kullanılabilir.
Ahşap malzemede aktif anti-bakteriyel özelliklerin defne ve kekik ekstraktları ile artırılması
Authors: ÖZKAN Osman Emre
Published: August 2022

Ahşap ürünler gün geçtikçe hayatımıza daha çok girmekle birlikte temas edilen ahşap yüzeylerin hijyenik olarak güvenli olup olmadığı ile ilgili bazı soru işaretlerini de beraberinde getirmektedir. Ahşap malzemenin pasif ve aktif olmak üzere iki farklı anti-bakteriyel özelliğinden bahsedilebilir. Burada, pasif anti-bakteriyel özellik ahşabın doğası gereği olan porozif yapısı ve higroskopisiteden kaynaklanmaktadır. Ancak, ahşabın aktif anti-bakteriyel özelliği ise odun içeriğinde bulunan ekstraktif maddeler ile ilişkilidir. Bu çalışmanın amacı, hijyenik açıdan hassas alanlarda kullanılmak üzere defne (Laurus nobilis) ve kekik (Origanum onites) ekstraktları ile muamele edilmiş odunların anti-bakteriyel özelliklerinin direk difüzyon yöntemi ile incelenmesidir. Deneyleri gerçekleştirmek için 10 farklı bakteri suşu kullanılmıştır. Deneylerde kullanılan ahşap diskler aktif anti-bakteriyel özellikleri düşük kavak (Populus tremula) ağacından hazırlandıktan sonra otoklav ile sterilize edilmiştir. Bakteri suşları 0,5 McFarland’da hazırlanarak sürüntü sürme yöntemiyle Mueller-Hinton agar petri kaplarına aşılanmıştır. Daha sonra odun diskleri doğrudan aşılanmış agar üzerine yerleştirilmiştir. 37 °C’de 24 saat inkübasyondan sonra, disklerin etrafındaki agar üzerindeki inhibisyon bölgesi mm olarak not edilmiştir. Elde edilen sonuçlara göre, kavak odununa uygulanan kekik ekstraktlarının bakteriyel büyümeyi azalttığı tespit edilmiştir. Böylece, anti-bakteriyel özelliği düşük olan ağaç türlerinin kekik ekstraktları ile muamele edilerek hijyenik açıdan hassas alanlarda kullanımının olumlu sonuçlar vereceği tespit edilmiştir.

Sürdürülebilir kırsal kalkınma anlayışında temel amaç, bölgenin kapasitesinin ve dolayısıyla kırsal iş gücü istihdamının artırılarak yoksulluk ile mücadele edilmesidir. Böylece yaşam kalitesi iyileştirilerek bölge insanının yeterli gelire sahip olması ile refah düzeyinin artırılarak kırsal tutunmanın sağlanması hedeflenir. Mut ilçesi fiziksel ve fiziksel olmayan problemler nedeniyle kırsal yaşamın az olduğu yerler arasında yer almaktadır. Bu nedenle son yıllarda, bu sorunlara yönelik pek çok tarımsal, altyapı, eğitim ve sağlık yatırımı almış, buna rağmen ilçe nüfusu 2007 yılından bu yana %4,65 azalmıştır. Bu azalışın en önemli nedenlerinden birisi ilçenin bir cazibe merkezi olma özelliği taşımamasıdır. Bu çalışmada ilçede gerek kırsalda tutunmayı artırarak göç etmeyi önlemek, gerekse yeni ziyaretçileri çekerek ilçeyi turizm açısından çekim merkezi haline getirebilmek amacıyla tematik turizm bölgesi modeli araştırması yapmak amaçlanmıştır. Bu araştırma sonucunda iki tematik rota önerisi ortaya çıkarılmıştır. Birincisi; II. Selim tarafından fethedilen Kıbrıs adasının Türkleştirilmesi amacıyla bölgeye gönderilen ahalinin geçiş güzergâhı olması nedeniyle Kıbrıs Yolu temalı yeni bir rota oluşturulmasıdır. İkincisi ise Antik Anadolu medeniyetleri dönemlerinden başlayarak Roma, Bizans ve Osmanlı İmparatorlukları da dâhil olmak üzere pek çok devletin hüküm sürdüğü ilçede birçok tarihi kalıntının bulunması sebebiyle Tarih Yolu temalı yeni bir model oluşturulmasıdır. Doğal ve kültürel mirasımızın korunması ve tanıtılmasında önemli işlevi olan kırsal turizm olanaklarının canlandırılması, başta bölgede istihdam olanaklarını genişleterek kırsal tutundurmayı sağlayabilir, ardından da Mut ilçesi özelinde Türkiye’nin de ülke olarak iç ve dış turizm gelirlerinin artmasına katkı sağlayabilir.

Published: August 2022

Çalışma kapsamında Ailanthus altisima tohumlarının çimlenmesi üzerine farklı yetiştirme ortamı ve ekim zamanının etkisinin belirlenmesi amaçlanmıştır. Ailanthus altisima tohumları, doğal tohum döküm zamanı olan Kasım ayı içerisinde KTÜ Kanuni kampüsünde bulunan ağaçlardan elde edilmiştir. Ekim işlemi önceden hazırlanmış özel ve yüksek ekim yastıklarında gerçekleştirilmiştir. Ekim işlemi, özel ekim yastıklarına kasım ve mart ayında, yüksek ekim yastığında ise ocak ayında gerçekleştirilmiştir. Tohumların ekimden önce 1000 tane ağırlıkları belirlenmiştir. Tohumlar, özel ekim yastıklarına kanatlı ve kanatsız olmak üzere iki farklı şekilde, yüksek ekim yastığında ise yalnız kanatlı tohumlar kullanılarak çizgi ekimi yöntemiyle ekilmiştir. Çalışma sonuçlarına göre Kasım ayında kanatlı veya kanatsız şekilde yapılan ekimin çimlenme yüzdesinin değişmesinde etkili olduğu ancak çimlenme için gerekli sıcaklık ve nemin rahatça alınabildiği ilkbahar mevsiminde tohumların kanatlı olup olmamalarının önemli olmadığı ve hemen hemen birbirine yakın çimlenme yüzdelerine (kanatlı tohum ÇY %94,17, kanatsız tohum ÇY %99,45) sahip oldukları saptanmıştır. Ailanthus altissima tohumları için uygun ekim zamanının ilkbahar olduğu tespit edilmiş olup, sonbaharda fidan ihtiyacının karşılanmasında başarılı bir sonucun elde edilebilmesi için ekim işleminin sera koşullarında yapılmasının uygun olacağı ortaya koyulmuştur.

Solaklı Vadisi (Trabzon) Doğu Karadeniz Bölümü’nde kuzeyden güneye doğru, sahilden 3376 m rakıma kadar yükselen ve toplam alanı 83000 hektar olan geniş bir havzadır. Havza bölge florası (Kolşik sektör) için kuzey-güney yönünde bir kesit özelliğine sahiptir. Yapılan flora ve vejetasyon çalışması sonucu, havzada yayılış gösteren toplam 141 adet vasküler yabancı bitki taksonu belirlenmiştir. Tespit edilen yabancı türlerden 34 adeti istilacı yabancı türdür. Geri kalan türler ise havzada doğallaşma süreçlerini tamamlayarak havza florasının bir parçası haline gelmiştir. Türkiye’de en dikkat çekici istilacı yabancı bitki olarak değerlendirilen 20 bitki taksonunun tümünün havzada yayılmakta olduğu saptanmıştır. Çalışmada ayrıca, havza özelinde istilacı yabancı bitkilerin bitkisel biyoçeşitlilik üzerine etkileri, ekolojik koşullar dikkate alınarak uygulanabilecek mücadele yöntemleri tartışılmıştır. Bu bağlamda ilgi gruplarının neler yapmasının ve nelerden kaçınmalarının uygun olacağı belirtilmiştir.
