İnsan siyasi ve sosyal yönü güçlü olan bir varlıktır. Sosyal bir varlık olması hasebiyle hayatını idame ve ikame ettirebilmek için kendinden farklı varlıklarla ilişki kurmak durumundadır. İnsan kendine karşı vazifeleri olan bir canlı olmasının yanında çevresindeki varlıklara -insan başta olmak üzere- karşı da sorumluluklar taşıyan akıllı ve iradeli bir varlıktır. Bu özellikleri taşıyan bireylerin bir araya gelerek gerek geniş gerekse dar kapsamlı olsun oluşturduğu toplulukların bir düzen ve intizam içerisinde, mutlu bir şekilde yaşayabilmeleri için bir öndere, bir yöneticiye ve bu yönetimin nasıl olacağını belirleyen kurallara ihtiyaç olduğu insani ve siyasi bir gerçekliktir. Bu çalışmamızda Mâverdî’nin “Edebü’d-Dünyâ ve’d-Dîn” adlı eserinde insanoğlunun en temel siyasi, sosyal ve ahlâki sorunu olan dünyanın düzeni için belirlemiş olduğu temel kaideleri değerlendirmeye çalışacağız. Mâverdî’nin söz konusu eserini inceleyince dinin, güçlü bir liderin ve herkesi kucaklayan adalet anlayışının ne kadar gerekli unsurlar olduğunu müşahede etmekteyiz. Yine Mâverdî’nin gerekli gördüğü kaideler arasında güvenlik, bolluk, bereket ve ufuk derinliği, engin bakış açısı gibi temel değerleri görmekteyiz.

Turizm, son zamanlarda ekonomik büyümenin önünü açan önemli bir sektör haline gelmiştir. Küreselleşmenin ortaya çıkması ve teknolojik gelişmenin ilerlemesiyle birlikte turizm sektörü daha da gelişerek büyük bir gelir potansiyeli olarak cazip hale gelmiştir. Turizm sektörünün cazip hale gelmesiyle sermaye sektöre doğru kayma eğilimi göstermiş, bu durumda kaynakların sınırsızca tüketilmesi ve çevresel tahribatın göz ardı edilmesini beraberinde getirmiştir. Çevresel tahribatın artması turizmde sürdürülebilirliğin gündeme gelmesine neden olmuştur. Çevreyi etkileyen bu olumsuzluklar çevreci bireylerin ve turizmin sürdürülebilirliğiyle birlikte yeni turizm anlayışlarının ortaya çıkmasına sebep olmuştur. Çalışmada Türkiye’de ekolojik turizm kavramı kalkınma planları içerisinde incelenmiştir. Bu kapsamda ilk olarak kalkınma ve sürdürülebilir kalkınma kavramları açıklanmış, küreselleşme kavramı çerçevesinde turizm değerlendirilmiştir. Daha sonra ekolojik turizmin sürdürülebilirliği ele alınarak Türkiye’deki kalkınma planları içerisinde ekolojik turizm kavramı incelenmiştir. Çalışma sonucunda Türkiye’deki Kalkınma Planları çerçevesinde ekolojik turizmin önemli ölçüde ele alınmadığı sonucuna varılmıştır.

Authors: DEMİREL Derya
Published: June 2021

Ermeniler Osmanlı Devleti’nde uzun yıllar millet-i sadıka olarak adlandırılmışlardır. 1877-1878 Osmanlı - Rus Savaşı’ndan sonra İngiltere ve Rusya’nın kışkırtmaları ile bağımsızlık talebinde bulunmaya başlamışlardır. Komiteler ve dernekler kurarak teşkilatlanma yoluna giden Ermeniler, Anadolu’da yoğun olarak yaşadıkları yerlerde isyan hareketleri başlatmışlardır. Bu dönemde Canik Sancağı’na bağlı Çarşamba Kazası’nda yaşayan Ermenilerin de 1894 - 1898 yılları arasında bir takım olaylar çıkararak asayişi bozdukları görülmektedir. Söz konusu olaylar; cinayet, gasp ve adam yaralama gibi hadiselerden ibarettir. Osmanlı arşiv belgelerinde belirtildiğine göre bölgede özellikle Minasoğlu çetesi etkili olmuştur. Dolayısıyla çıkarılan olaylar planlı ve siyasi maksadı haiz olaylardır. Osmanlı Devleti kimi zaman askeri tedbirler kimi zaman ise bölge halkına sunulan nasihatnâme tarzında yazılmış beyannâmeler ile Ermeni çetelerinin zararlı faaliyelerini engellemeye çalışmıştır. Ermeni nüfusunun bölgede Türk ve Müslüman nüfusa kıyasla az olmasının da etkisiyle çıkarılan olaylar, alınan tedbirler sayesinde büyümeden bastırılabilmiş; topluca isyan diye nitelendirilebilecek olaylar yaşanmamıştır.

One of the modern trends in the development of communication systems, information and telecommunication systems, air traffic control systems, etc. is the transition and development of higher-frequency wavelength ranges. In this regard more and more stringent requirements (in terms of spectrum, out-of-band and spurious radio emission, and in the shape of the output signal) are imposed on radio engineering devices that transmit and receive microwave radio signals. As a result, the requirements for the design and functional features of microwave electronic devices are increasing. One of these requirements is to assess the degree of compliance with the required values of dielectric properties of materials used in the design of microwave electronic devices. This requirement is justified by the fact that the electrical parameters of such microwave devices as: strip filters, power dividers, printed antennas and others, directly depend on the dielectric properties of the materials used in their substrate designs. In this regard, three main methods have now emerged for assessing the dielectric properties of materials: the resonant method, the non-resonant method, and the free space method. Aim. The aim of this article is to carry out a comparative analysis of the known methods for measuring the dielectric properties of materials in the microwave range of wavelengths and devices for their implementation. Materials and methods. The authors of the article reviewed the scientific literature of domestic and foreign publications. Results. For each of the methods for measuring the dielectric properties of materials, their main idea, practical implementation, a mathematical model for processing experimental data and areas of application are given. The advantages and disadvantages for each of the methods for measuring the dielectric properties of materials are given too. Conclusion. The applicability of each of the considered methods depends on such factors as: the shape of the investigated dielectric material, its state of aggregation, the possibility of measuring amplitude or complex transmission and reflection coefficients, the presence of an anechoic chamber, etc.

Nowadays, digital games have become a part of the daily lives of individuals, and accordingly, the virtual world phenomenon, especially in the young population, has emerged. This phenomenon causes digital game users to experience other worlds as well as their real lives. The experiences of individuals through games in the virtual environment, on the one hand, provide link and communication, on the other hand, they distance them from concrete concepts of the real world. This study aimed to examine the digital game-playing attitudes of students studying at the faculties of sports sciences. The research group consisted of 911 students (415 females, 45.6%; 496 males, 54.4%) studying at the faculties of sports sciences in Konya Selcuk University, Ankara Gazi University, and Istanbul University-Cerrahpaşa. This study conducted in the period of November-December, 2019, and all students voluntarily participated in the study. The “Digital Gaming Attitude Scale (DGAS)” developed by Tekkurşun Demir and Mutlu Bozkurt (2019) was used to collect data in the study. This scale consists of 18 items and three sub-dimensions (cognitive, affective, and behavioral). Descriptive statistics (frequency, arithmetic mean, standard deviation), independent sample t-test, one-way analysis of variance (ANOVA), and Tukey multiple comparison tests were used in the analysis of the data. The arithmetic mean of the sub-dimensions was 15.41 ± 3.38 for cognitive, 15.72 ± 3.74 for emotional, and 23.58 ± 7.34 for behavioral. Statistical analysis of the data was made through the SPSS 19.0 program and the significant difference level of the values was accepted as p <0.05.

Purpose: Not only in daily conversations, official correspondence, and educational settings but also on social media platforms, the correct usage of language by prospective teachers has become a necessity of the age. Twitter, which is used by many people to express their feelings, opinions, etc., is used actively by prospective teachers as well. The present study aimed to investigate the grammatical errors in prospective classroom teachers’ tweets. Method: The study employed the case study method, one of the qualitative research methods. The data were analyzed through the document analysis method. A total of three hundred tweets posted by 30 prospective teachers were analyzed. Descriptive analysis was used to analyze the data. The grammatical errors to look for in the tweets were determined based on the learning outcomes related to grammar rules specified in the Turkish Language Curriculum designed for primary schools (2019). Findings: Considering the overall results, the vast majority of tweets contained grammatical errors. It was also determined that the grammatical errors were similar in terms of their types. Punctuation errors, inverted sentences, spelling errors, and capitalization errors were some common grammatical errors. On the other hand, misspelled numbers, incorrect abbreviations, and the use of 'reinforced words' (words with a prefix to add emphasis) were rare grammatical errors. When the results were analyzed according to genders, it was found that males' tweets contained more grammatical errors than those of females. In both genders, punctuation errors, inverted sentences, misspellings, and incorrect capitalization were common grammatical errors. On the other hand, misspelled numbers, incorrect abbreviations, and the use of 'reinforced words' (words with a prefix to add emphasis) were rare grammatical errors. In conclusion, it can be said that a majority of tweets posted by prospective teachers contained grammatical errors and these grammatical errors were similar in terms of their types. Implications for Research and Practice: Also, similar studies can be carried out on the use of written language on other social media platforms such as YouTube, WhatsApp, Instagram, and Facebook, which also have millions of users.

Authors:   University of Indonesia, Indonesia, Triana Lidya
Published: June 2021

This study puts personal, social, and religious resources as a stress buffer for caregivers. The limitation of personal, social, religious resources have a detrimental effect on the mental health of caregivers of a family member with schizophrenia (hereinafter referred to as People with Schizophrenia, or PwS). Following the caregiving stress process theory, this study aims to clarify not only the role of personal and social resources but also the religious ones. For this purpose, in-depth interviews with a life history method were done to twenty (20) caregivers of PwS. The result shows that personal resources like coping mechanism management (for example, by doing a positive comparison with others and reducing the expectations on the PwS) would help to perceive the role of a caregiver more positively. Meanwhile, social resources like social support were received by the caregivers from their significant others (family members) and similar others (support group). Social support was received in the form of emotional support, caregiving help, and instrumental aid. Religious resources in the form of religious coping were also used as a buffer for the stress that came from caregiving. This was done by positive religious coping, such as asking for help from God during difficult times, involving God in everything they do, and surrendering themselves to God to get the strength to face life problems. These three resources (personal, social, religious) were needed by the caregivers so they can preserve their mental health.

The study aimed to find out the risk factors for enteric fever in hospitalized children in a tertiary care hospital. Methodology: We conducted a hospital-based case-control study to identify the risk factors in children residing in Dhaka city. We enrolled 50 enteric fever cases as a case group and 50 age-matched febrile patients as a control group. Result: Out of 50 cases, 2 patients were below one year and most of them were pre-school aged 26(52%). Univariate analysis showed that enteric fever is more who take food with the help of the mother and caregiver (OR=7.1); 95% CI= 26.7 -61.3) and never or rarely wash hands before preparing food and before feeding (OR= 5.7; 95% CI= 23.2 -52.8). Cases were eating outdoors at the mobile food vendors and consuming ice-cream regularly (OR=2.28; 95% CI=1- 39) whereas the control group also took street food but less frequently. Conclusion: Enteric fever is an exclusive food and water-borne systemic disease and one of the major public health problems in Bangladesh. Not only overcrowding, unsafe drinking water are the common risk factors but also hand washing both children and caregiver, poor food habit is the important risk factors. So, health education to children and food handlers may reduce the incidence of enteric fever in children.

Optimum fish production is greatly dependent on the physical, chemical and biological qualities of water. Hence, successful fish pond management requires an in-depth understanding of water quality. A study to assess heavy metal (Cr, Cd, Mn, Pb and Zn) contamination and physicochemical parameters of water samples from eight selected fish ponds in Sunyani, Ghana, was conducted. The parameters included temperature, pH, salinity, total hardness, electrical conductivity (EC), chemical oxygen demand (COD) and biological oxygen demand (BOD). The results revealed detectable Mn and Zn levels in all the selected fish ponds; with Mn levels in three ponds being significantly higher than the World Health Organization (WHO) recommended limit (< 0.500 mg/L). Of the three samples, which showed detectable Cr and Cd levels, concentrations of two exceeded the permissible limits. Pb was below the detection limit in all the samples whilst Cu levels detected in two of the ponds were below the permissible limit. The investigated physicochemical parameters had the following ranges: temperature 26-29 C, pH 5.8-8.2, BOD 0.3-20 mg/L, Total Dissolved Solids (TDS) 37-249 mg/L, EC 73.67-498 μS/cm, total hardness 0.8-5.7 mg/L, salinity 0.03-0.22 psu and COD 2.9-9.7 mg/L. Most of these values were within WHO recommended levels. The findings suggest that regular monitoring of the heavy metal load is necessary to guard against long-term effects of its presence in the water, influencing fish and human uptake.

The Role of Personal, Social and Religious Resources in Caregiving Stress
Authors: Triana Lidya
Published: June 2021

This study puts personal, social, and religious resources as a stress buffer for caregivers. The limitation of personal, social, religious resources have a detrimental effect on the mental health of caregivers of a family member with schizophrenia (hereinafter referred to as People with Schizophrenia, or PwS). Following the caregiving stress process theory, this study aims to clarify not only the role of personal and social resources but also the religious ones. For this purpose, in-depth interviews with a life history method were done to twenty (20) caregivers of PwS. The result shows that personal resources like coping mechanism management (for example, by doing a positive comparison with others and reducing the expectations on the PwS) would help to perceive the role of a caregiver more positively. Meanwhile, social resources like social support were received by the caregivers from their significant others (family members) and similar others (support group). Social support was received in the form of emotional support, caregiving help, and instrumental aid. Religious resources in the form of religious coping were also used as a buffer for the stress that came from caregiving. This was done by positive religious coping, such as asking for help from God during difficult times, involving God in everything they do, and surrendering themselves to God to get the strength to face life problems. These three resources (personal, social, religious) were needed by the caregivers so they can preserve their mental health.

The present investigation was carried out to explore the bio-activities of Enantia chlorantha Oliv (Annonaceae) commonly known as African yellow wood. The root, stem and leaf of E. chlorantha were extracted with ethanol in soxhlet extractor. Their phytochemical analysis revealed presence of alkaloids, flavonoids, saponins, phenols, steroids, cardiac glycosides, terpenoids, anthraquinones, proteins, aldehydes/ketones and carboxylic acids in all the extracts except leaves extract which contain tannins in addition. The extracts were screened in vitro for their antibacterial activities against Gram-positive bacteria (Bacillus thuringensis strain EB-151, Bacillus tequilensis strain ADIP3, Bacillus cereus strain SB2, Bacillus pumilus strain m414, Sphingobacterium mizutaii strain AUMC b-161, Bacillus subtilis strain AIMST 2ME1, Bacillus cereus strain CF7 and Lysinbacillus sphaericus III) and Gram-negative bacteria (Providencia rettgeri strain RCB 200, Proteus vulgaris strain MWG 20141026, Alcaligenes faecalis strain L48, Pseudomonas aeruginosa strain PG1, Pseudomonas aeruginosa strain 335K55 and Escherichia coli strain sanji.); out of which eight of strains were susceptible to the extracts and six were resistant to all the extracts. This study has opened a frontier for the possible application of the extracts in the control of potential pathogens.

Authors: Chemistry International CI
Published: June 2021

Total petroleum hydrocarbons (TPH) as well as the aliphatic profiles of surface water at the Okpu and Iyiowa-Odekpe sections of the River Niger in South-Eastern Nigeria were determined. Composites samples taken from surface water at three different locations (ST-1, ST-2, & ST-3) for the months of June, September, December and February, were extracted with dichloromethane (DCM) by liquid-liquid partition and analyzed for TPH and aliphatic components using gas chromatography-flame ionization detection (GC-FID). The results reveal a TPH range of 1658.475-5435.742 μg/L with a mean of 2596.523±492.466 μg/L. The mean value for the raining season (3283.783±1253.99 μg/L) was significantly higher than that of the dry season (1909.429±190.866 μg/L). Values for all the months at all sampled locations were also much higher than the European Union (EU) standard limit of 300 μg/L. Aliphatic hydrocarbon source diagnostics ratios gave range of: even to odd numbered n-alkanes ratio (0.162–2.371), carbon preference index -CPI (0.702–1.581), sum of low molecular weight to high molecular weight n-alkanes (0.0275–1.152), nC31/nC19 (0.00–49.72), sum of long chain hydrocarbons to short chain hydrocarbons (0.824–38.03), and pristane/phytane ratio (ND–0.26); indicating that the TPH in the water were from both biogenic and anthropogenic inputs with biogenic sources that are largely terrestrial. This calls for necessary actions to reduce the anthropogenic inputs of TPH in the water so as to protect the aquatic ecosystem and sustain public health.
Green synthesis of copper nanoparticles by Citrus limon fruits extract, characterization and antibacterial activity
Authors: Chemistry International CI
Published: June 2021

In view of advantages of green synthesis, a novel green route for the synthesis and stabilization of copper nanoparticles (CuNPs) using aqueous extract of Citrus limon fruits at room temperature was reported. The formation of CuNPs is monitored by recording the UV–vis absorption spectra for surface Plasmon resonance (SPR) peak (∼579 nm). X-ray diffraction (XRD) pattern of the CuNPs agrees with the reported data for Cu metal and the crystallite average size is ~30 nm. Scanning and transmission electron microscopic (SEM and TEM) show uniform spherical particles obtained by this green method. The antimicrobial activity is found to be effective of CuNPs. Results revealed that the green synthesis is an efficient for the preparation of CuNPs as an active antimicrobial agent for practical applications.
Кинетика газа в галактических дисках объясняет кривые вращения спиральных галактик без привлечения тёмной материи.
Authors: Lipovka Anton A.
Published: June 2021

В настоящей работе показано, что повсеместно используемые методы классической механики не могут применяться для вычисления кривых вращения во внешних частях дисков, где влияние столкновений в газе на его динамику становится доминирующим. Более того, гидродинамический подход так же не применим для этих целей всилу крайней разреженности газа в галактических дисках. В этом случае должен быть развит новый аппарат для описания динамики разреженного газа во внешних областях дисков, где динамика газа определяется преимущественно столкновениями.В работе выводятся уравнения описывающие динамику газа, но свободные от ограничений налагаемых на гидродинамику. Полученные уравнения связывают две величины: тангенциальную скорость газа, как функцию расстояния от центра галактики (кривую вращения) и радиальное распределение плотности газа. Показано, что при корректном учёте физических свойств разреженного газа, не требуется введение тёмной материи и «нефизичные» (не Кеплеровы) кривые вращения для внешних частей галактик являются ветровыми хвостами и описывамыми в рамках обычной кинетики газа.Для иллюстрации правильности полученной модели (уравнение 14), рассмотрены две галактики с плоскими кривыми вращения (NGC7331 и NGC3198). Получено прекрасное согласие между плотностями рассчитанными из кривой вращения (используя выражение 14) и наблюдаемыми величинами, что подтверждает корректность используемой модели. Таким образом «нефизичные» кривые вращения спиральных галактик, для объяснения которых привлекается тёмная материя – это всего лишь ветровые хвосты, образующиеся в разреженном газе и для их объяснения не требуется привлечение концепции тёмной материи.Вычислены полные массы галактик NGC7331 и NGC3198. Обсуждаются следствия для космологии.

Nowadays, digital games have become a part of the daily lives of individuals, and accordingly, the virtual world phenomenon, especially in the young population, has emerged. This phenomenon causes digital game users to experience other worlds as well as their real lives. The experiences of individuals through games in the virtual environment, on the one hand, provide link and communication, on the other hand, they distance them from concrete concepts of the real world. This study aimed to examine the digital game-playing attitudes of students studying at the faculties of sports sciences. The research group consisted of 911 students (415 females, 45.6%; 496 males, 54.4%) studying at the faculties of sports sciences in Konya Selcuk University, Ankara Gazi University, and Istanbul University-Cerrahpaşa. This study conducted in the period of November-December, 2019, and all students voluntarily participated in the study. The “Digital Gaming Attitude Scale (DGAS)” developed by Tekkurşun Demir and Mutlu Bozkurt (2019) was used to collect data in the study. This scale consists of 18 items and three sub-dimensions (cognitive, affective, and behavioral). Descriptive statistics (frequency, arithmetic mean, standard deviation), independent sample t-test, one-way analysis of variance (ANOVA), and Tukey multiple comparison tests were used in the analysis of the data. The arithmetic mean of the sub-dimensions was 15.41 ± 3.38 for cognitive, 15.72 ± 3.74 for emotional, and 23.58 ± 7.34 for behavioral. Statistical analysis of the data was made through the SPSS 19.0 program and the significant difference level of the values was accepted as p <0.05. The analysis results showed that when the digital gaming attitude scale was evaluated according to gender, the mean score scores of male students in all cognitive, affective, and behavioral sub-dimensions were significantly higher than female students.
