Authors: Wang Panxian , Ren Zimeng , Qiao Guanghua
Published: June 2023

The liberalization of world trade has led to a significant increase in agricultural trade, which has brought to light various environmental externalities, including climate change, deforestation, and water pollution. While economic studies tend to overlook the environmental effects of agricultural trade liberalization, recent research has shown a growing interest in related aspects. As such, it is crucial to conduct a comprehensive analysis of the environmental impacts of agricultural trade liberalization. This study aims to address this issue by conducting a systematic review of the relevant literature from the past two decades. Research has revealed that agricultural trade liberalization has both positive and negative impacts on the environment. The various mechanisms through which these effects are observed include scale, structural, transport, and technology effects. Most studies have concluded that agricultural trade liberalization has a significantly negative impact on the environment. To address this issue, four potential solutions have been proposed, including factor allocation, policy adjustment, technological innovation, and improvements to compensation mechanisms. Future research should aim to develop a comprehensive model that can effectively examine the environmental impacts of agricultural trade policy distortions and the criteria used to select environmental measures. By doing so, we can gain a deeper understanding of the complex relationship between agricultural trade policies and their environmental consequences.

Authors: Wang Dan , Liu Yan , Cheng Yu
Published: June 2023

Manufacturing agglomeration is an important manifestation for cities to enhance their competitiveness, and the resource and environmental effects caused by agglomeration have become a hot topic. Based on the relevant data of prefecture-level cities in the Yellow River Basin from 2006 to 2019, this study used a Markov transition matrix to study the characteristics of carbon emission transfer and constructed an SDM model to analyze the effect of manufacturing agglomeration on carbon emissions and spatial spillover; the study drew the following conclusions: carbon emissions and the concentrations of manufacturing industries in the Yellow River Basin are on the rise, with carbon emissions showing a distribution pattern of “downstream > midstream > upstream”. Manufacturing agglomeration has a significant positive influence on carbon emissions, reflecting the necessity for the green transformation of manufacturing agglomeration. Manufacturing agglomeration has a spatial spillover effect on carbon emissions. The direct effect is positive, and the indirect effect is negative. The polarization effect caused by agglomeration weakens the development degree of neighboring areas, which may reflect the technological spillover effect of manufacturing agglomeration on neighboring areas. Manufacturing agglomeration has regional heterogeneity in carbon emissions. Compared with the middle and lower reaches of the Yellow River Basin, the effect is more obvious in the upper reaches. The study proposes countermeasures in terms of optimizing the spatial pattern of the manufacturing industry and other aspects to provide references for promoting the transformation development of the manufacturing industry in the Yellow River Basin.

Authors: Zhang Qian , Tian Shaopeng
Published: June 2023

The development of hybrid technology can effectively solve the problems of the high pollution and energy consumption levels of automobiles. Therefore, an energy consumption prediction and control algorithm for hybrid vehicles based on a minimum equivalent fuel consumption model is proposed. The model’s battery power consumption is equivalent to the fuel consumption, and the sum of the engine fuel consumption and the battery equivalent fuel consumption is established as the objective function. By utilizing these factors, an innovative minimum equivalent fuel consumption model was constructed that could be used to measure the energy efficiency of hybrid vehicles. The longitudinal force result of braking force distribution control was obtained, as well as the energy consumption prediction structure of a hybrid electric vehicle. The rolling resistance, air resistance, and climbing resistance of the hybrid electric vehicles were calculated, and the energy consumption control algorithm for hybrid electric vehicles was constructed according to the calculation results. The experimental results indicated that under this research algorithm, the driving energy consumption of hybrid electric vehicles was relatively low and the energy consumption and energy efficiency measurements effectively met the actual demand, and the energy consumption prediction and control results were good.

Published: June 2023

Even though waste pickers play a crucial role in the urban solid waste management system in developing countries, their social, familial, and labor conditions remain uncertain. In this study, we analyzed the profiles of waste pickers in Colombia using multivariate statistical methods and cluster analysis. Our findings indicate that the majority of waste pickers have only completed elementary or high school education, and most of them are not associated with any organization and belong to the subsidized health regime. We identified five profiles of waste pickers in the population. The first consists of the most experienced individuals, while the second comprises individuals with the lowest salaries. The third includes older individuals who work more hours per day. The fourth is made up of individuals who work in the informal sector, and the fifth includes individuals who work in the formal sector. Our study highlights specific actions to be taken for each profile. Improving family and household conditions, social and educational status, and job conditions can have a significant impact on their lives.
Failure Mechanism of Anti-Dip Layered Soft Rock Slope under Rainfall and Excavation Conditions
Authors: Jia Jun , Pei Xiangjun , Liu Gang , Cai Guojun , Guo Xiaopeng , Hong Bo
Published: June 2023

The phenomenon of toppling deformation and failure is common in slopes with anti-dip structures, especially in soft metamorphic rock slopes. This paper aims to explore the instability mechanism of anti-dip layered soft metamorphic rock landslides. Taking the slope of a mining area in the southern Qinling Mountains of China as a geological prototype, a large-scale centrifuge model test and a numerical simulation based on the combined finite and discrete element method (FDEM) were performed. The deformation and failure process, failure mode, and failure path of the slope under rainfall and excavation conditions were simulated. The results show that both the physical centrifuge model test and the new numerical model test can simulate the instability process of anti-dip layered soft metamorphic rock slopes, and the phenomena simulated by the two methods are also very close. Rainfall mainly weakens the mechanical properties of rock, while the excavation at the slope toe mainly changes the stress field distribution and provides space for slope deformation, both of which accelerate the instability of the anti-dip soft metamorphic rock slope. The failure process of an anti-dip layered soft rock slope can be described as follows: bending of the rock layer–tensile fracture along the layer–flexural toppling and cracking perpendicular to the rock layer–extension and penetration of the tensile fracture surface–sliding and instability of the slope.

Published: June 2023

Seabed trenches reduce anchor capacity. However, the adverse influence is not considered in the current design, and no guideline is found in engineering practice. This paper presents a framework for mooring and anchor design in sand considering seabed trenches based on floater hydrodynamics. First, a hydrodynamic calculation of the studied floater coupled with the mooring system was conducted. Then, the potential trench profile was assessed using a mooring line–seabed dynamic model. Third, after assessing the suction anchor performance based on its installation and capacity, a refined anchor, caisson–plate gravity anchor (CPGA), was proposed, and the capacity mechanisms were analyzed. It was found that the tensions of mooring lines l1 and l2 resist maximum loads under a 45° load condition. Due to the sand’s high strength, a trench is difficult to form in this mooring type. The suction anchor is not suitable as an anchor for the carbonate sand, considering its installation and capacity. The analyses indicate that the increase in soil stress and soil mobilized range in front of the caisson promotes the capacity of CPGA. This paper provides a framework/example to design moorings and anchors considering potential trenches and provides a solution to the anchor design in carbonate sand.
Research on Intelligent Emergency Resource Allocation Mechanism for Public Health Emergencies: A Case Study on the Prevention and Control of COVID-19 in China
Authors: Ma Ruhao , Meng Fansheng , Du Haiwen
Published: June 2023

The outbreak of COVID-19 posed a significant challenge to the emergency management system for public health emergencies, especially in China, where the epidemic began. As intelligent technology has injected new vitality into emergency management, applying intelligent technology to optimize emergency resource allocation (ERA) has become a focus of research in the post-epidemic era. Based on China’s experience in preventing and controlling COVID-19, this paper first analyzes the characteristics and process of ERA in public health emergencies, and then synthesizes the relevant Chinese studies in recent years to identify the intelligent technologies affecting ERA in China using word frequency analysis technology. We also construct an intelligent emergency resource allocation mechanism in four areas: medical intelligence, management intelligence, decision-making intelligence, and supervision intelligence. Finally, we use the entropy-TOPSIS method to evaluate the impact of intelligent technologies on ERA, and we rank the criticality of intelligent technologies. The experimental results show that (i.) medical intelligence and management intelligence are the keys to developing intelligent ERA, and (ii.) among the identified essential intelligent technologies, artificial intelligence (AI), and big data technology have a more significant and critical role in emergency resource intelligence allocation.
An Improved User Requirements Notation (URN) Models’ Construction Approach
Authors: Dongmo Cyrille , Van der Poll John Andrew
Published: June 2023

Semi-formal software techniques have been very successful in industry, government institutions and other areas such as academia. Arguably, they owe a large part of their success to their graphical notation, which is more human-oriented than their counterpart text-based and formal notation techniques. However, ensuring the consistency between two or more models is one of the known challenges of these techniques. This work looks closely at the specific case of the User Requirements Notation (URN) technique. Although the abstract model of URN provides for link elements to ensure the consistency between its two main components, namely, Goal-Oriented Requirement Language (GRL) and Use Case Maps (UCM), the effective implementation of such links is yet to be fully addressed. This paper performs a detailed analysis of the existing URN models construction process and proposes an improved process with some guidelines to ensure, by construction, the correctness and consistency of the GRL and UCM models. A case study is used throughout the paper to illustrate the suggested solution.
Homogeneous Cosmological Models in Weyl’s Geometrical Scalar–Tensor Theory
Authors: Barros Adriano , Romero Carlos
Published: June 2023

In this paper, we consider homogeneous cosmological solutions in the context of the Weyl geometrical scalar–tensor theory. Firstly, we exhibit an anisotropic Kasner type solution taking advantage of some similarities between this theory and the Brans–Dicke theory. Next, we consider an isotropic model with a flat spatial section sourced by matter configurations described by a perfect fluid. In this model, we obtain an analytical solution for the stiff matter case. For other cases, we carry out a complete qualitative analysis theory to investigate the general behaviour of the solutions, presenting some possible scenarios. In this work, we do not consider the presence of the cosmological constant nor do we take any potential of the scalar field into account. Because of this, we do not find any solution describing the acceleration of the universe.
Compact Stars in the vBag Model and Its f-Mode Oscillations
Authors: Zhou Heng-Yi , Wei Wei , Zhou Xia
Published: June 2023

Electromagnetic (EM) observations and gravitational wave (GW) measurements enable us to determine the mass and radius of neutron stars (NSs) and their tidal deformability, respectively. These parameters offer valuable insights into the properties of dense matter in NSs. In this study, the vector-interaction-enhanced bag model (vBag model) is employed to investigate strange and hybrid stars’ properties. The parameters of the vBag model are constrained using multi-messenger observations, revealing that strange stars are incompatible with current observations. In contrast, hybrid stars can exhibit a substantial mixed phase region and a thin hadronic shell. Furthermore, we present the frequencies and damping time of fundamental mode (f-mode) oscillations of hybrid stars and test their universal relations with compactness and tidal deformability. The findings indicate that the presence of mixed phase components leads to larger frequencies and shorter damping time of the f-mode oscillation of hybrid stars, and the softer equation of state (EoS) affects this behavior more significantly. The universal relations of hybrid stars in the vBag model can be described by fourth-order/seventh-order polynomials, which do not break the previous results.

Authors: Serrano Montesinos Ramón , Morales-Lladosa Juan Antonio
Published: June 2023

We conduct a detailed study of the electromagnetic field produced by a massive point particle undergoing hyperbolic (uniformly accelerated) motion in Minkowski space-time. Starting from the Liénard–Wiechert solution and using a covariant notation, we obtain and analyse the main quantities that describe this field. We identify the space-time region to which this solution is restricted and write a solution valid in the whole of space-time. Finally, we verify that this solution satisfies Maxwell’s equations in the sense of distributions.

Anti-SARS-CoV-2 vaccination leads to the production of neutralizing as well as non-neutralizing antibodies. In the current study, we investigated the temporal dynamics of both sides of immunity after vaccination with two doses of Sputnik V against SARS-CoV-2 variants Wuhan-Hu-1 SARS-CoV-2 G614-variant (D614G), B.1.617.2 (Delta), and BA.1 (Omicron). First, we constructed a SARS-CoV-2 pseudovirus assay to assess the neutralization activity of vaccine sera. We show that serum neutralization activity against BA.1 compared to D614G is decreased by 8.16-, 11.05-, and 11.16- fold in 1, 4, and 6 months after vaccination, respectively. Moreover, previous vaccination did not increase serum neutralization activity against BA.1 in recovered patients. Next, we used the ADMP assay to evaluate the Fc-mediated function of vaccine-induced serum antibodies. Our results show that the antibody-dependent phagocytosis triggered by S-proteins of the D614G, B.1.617.2 and BA.1 variants did not differ significantly in vaccinated individuals. Moreover, the ADMP efficacy was retained over up to 6 months in vaccine sera. Our results demonstrate differences in the temporal dynamics of neutralizing and non-neutralizing antibody functions after vaccination with Sputnik V.

Published: June 2023

A large amount of real-world data suggests that the emergence of variants of concern (VOCs) has brought new challenges to the fight against SARS-CoV-2 because the immune protection elicited by the existing coronavirus disease 2019 (COVID-19) vaccines was weakened. In response to the VOCs, it is necessary to advocate for the administration of booster vaccine doses to extend the effectiveness of vaccines and enhance neutralization titers. In this study, the immune effects of mRNA vaccines based on the WT (prototypic strain) and omicron (B1.1.529) strains for use as booster vaccines were investigated in mice. It was determined that with two-dose inactivated vaccine priming, boosting with mRNA vaccines could elevate IgG titers, enhance cell-mediated immunity, and provide immune protection against the corresponding variants, but cross-protection against distinct strains was inferior. This study comprehensively describes the differences in the mice boosted with mRNA vaccines based on the WT strain and the omicron strain, a harmful VOC that has resulted in a sharp rise in the number of infections, and reveals the most efficacious vaccination strategy against omicron and future SARS-CoV-2 variants.

Published: June 2023

Influenza vaccination can benefit most populations, including adults ≥ 65 years of age, who are at greater risk of influenza-related complications. In many countries, enhanced vaccines, such as adjuvanted, high-dose, and recombinant trivalent/quadrivalent influenza vaccines (aTIV/aQIV, HD-TIV/HD-QIV, and QIVr, respectively), are recommended in older populations to provide higher immunogenicity and increased relative vaccine efficacy/effectiveness (rVE) than standard-dose vaccines. This review explores how efficacy and effectiveness data from randomized controlled trials and real-world evidence (RWE) are used in economic evaluations. Findings from published cost-effectiveness analyses (CEA) on enhanced influenza vaccines for older adults are summarized, and the assumptions and approaches used in these CEA are assessed alongside discussion of the importance of RWE in CEA. Results from many CEA showed that adjuvanted and high-dose enhanced vaccines were cost-effective compared with standard vaccines, and that differences in rVE estimates and acquisition price may drive differences in cost-effectiveness estimates between enhanced vaccines. Overall, RWE and CEA provide clinical and economic rationale for enhanced vaccine use in people ≥ 65 years of age, an at-risk population with substantial burden of disease. Countries that consider RWE when making vaccine recommendations have preferentially recommended aTIV/aQIV, as well as HD-TIV/HD-QIV and QIVr, to protect older individuals.

Published: June 2023

Currently available COVID vaccines are effective in reducing mortality and severity but do not prevent transmission of the virus or reinfection by the emerging SARS-CoV-2 variants. There is an obvious need for better and longer-lasting effective vaccines for various prevailing strains and the evolving SARS-CoV-2 virus, necessitating the development of a broad-spectrum vaccine that can be used to prevent infection by reducing both the transmission rate and re-infection. During the initial phases of SARS-CoV-2 infection, the nucleocapsid (N) protein is one of the most abundantly expressed proteins. Additionally, it has been identified as the most immunogenic protein of SARS-CoV-2. In this study, state-of-the-art bioinformatics techniques have been exploited to design novel multiple epitope vaccines using conserved regions of N proteins from prevalent strains of SARS-CoV-2 for the prediction of B- and T-cell epitopes. These epitopes were sorted based on their immunogenicity, antigenicity score, and toxicity. The most effective multi-epitope construct with possible immunogenic properties was created using epitope combinations. EAAAK, AAY, and GPGPG were used as linkers to connect epitopes. The developed vaccines have shown positive results in terms of overall population coverage and stimulation of the immune response. Potential expression of the chimeric protein construct was detected after it was cloned into the Pet28a/Cas9-cys vector for expression screening in Escherichia coli. The developed vaccine performed well in computer-based immune response simulation and covered a diverse allelic population worldwide. These computational findings are very encouraging for the further testing of our candidate vaccine, which could eventually aid in the control and prevention of SARS-CoV-2 infections globally.

Published: June 2023

Mastitis is one of the most considerable and costly diseases for dairy herds, and Staphylococcus spp. is known to be the main causative agent. Although antibiotics are widely used in the treatment of mastitis, this can cause both antibiotic residues in milk and the risk of antibiotic resistance occurrence in bacteria. Thus, in recent years, researchers have focused on alternative treatments for this disease and plants extracts are investigated for this purpose. Pomegranate is widely used as a dye, ornament, and medicinal plants in the industry, and the species has a particularly high economic value in Turkey. This study aims to investigate in vitro the antioxidant and antibacterial properties of the pomegranate flower’s extracts against different Staphylococcus species associated with bovine mastitis. To this aim, pomegranate flowers were collected from different regions in Turkey and extracts were prepared with three different solvents (methanol, ethanol, and water). The retention factor values of the ethanol extract were determined by thin-layer chromatography. The antibacterial activity tests were carried out via the disk diffusion method. In addition, the extracts were tested against the stable DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) free radicals for antioxidant activity. Four retention factors (0.79, 0.67, 0.58, and 0.33 points) were found for the ethanol extract. The methanol extract showed the highest inhibition zones against coagulase-negative Staphylococcus-37 (CNS-37) and S. aureus-18. The lowest MIC was 6500 μg/mL. The highest antioxidant activity was observed in methanol extracts. As a result, the extracts of pomegranate flowers showed a high antioxidant and antibacterial potential against the examined mastitis pathogens.

Published: June 2023

In 2013, a slope slide took place at the Santana-AP channel that links to the Lower Amazon River’s North Channel, resulting in the sudden collapse of a substantial section of the Port of Santana and its infrastructure. This area houses liquid bulk terminals and pipelines with high pollution potential. The objective of the research is to evaluate the potential environmental impacts of an eventual oil spill in the very short term using a numerical hydrodynamic simulation model coupled with that of pollutant dispersion. The SisBaHiA® software, experimentally calibrated using acoustic methods (ADCP), was used to generate hypothetical scenarios in these areas with a substantial risk of landslides. Two hydrological scenarios stand out in the simulations: (a) November S-1 (dry) and (b) May S-2 (rainy). In S-1, the plume dispersion was higher during flood tides S-1a and S-1b, reaching 4 h urban slope areas, river mouths, tributaries (Matapi and Vila Nova), and environmental protection areas. At S-2, the plume spread was greater during the ebb tides S-2c and S-2d, affecting Macapá’s water supply system 12 h after the accident. The scenarios suggest the existence of high risks associated with the study hypotheses. The dispersion of the plume is directly proportional to the flow, indicating that local hydrodynamics is probably the most relevant dispersive factor. We conclude that the mitigation time for more severe effects is critical in the first 4 h because the coastal geographic feature tends to keep the plume in the Santana channel.

IoT Based Technique for Network Packet Analyzer
Authors: Alhindawi Nouh
Published: June 2023

Network demands are expanding dramatically, especially in educational sectors where systems are acting in a non-tradition network environment. Most of the services are published on the cloud so students can access teaching or learning materials directly; such demand is a heavy burden to systems administrators who needs to monitor critical educational services around the clock. However, such solutions need efforts, money, time, and space to be built; in this paper, the Internet of Things (IoT) is proposed as a small and cheap device that can be installed and configured to analyze packets locally for each service while analyzed logs can be synced simultaneously to have a complete view about systems behavior from any location for the education’s system. Based on the results, the proposed approach showed a significant solution for the heavy demands on the educational system. Moreover, the results showed that the presented approach is more efficient when compared to the state of art packet analysis and monitoring approaches.

Published: June 2023

Unmanned Aerial Vehicle )UAV( finds its significant application in video surveillance due to its low cost, high portability and fast-mobility. In this paper, the proposed approach focuses on recognizing the human activity in aerial video sequences through various keypoints detected on the human body via OpenPose. The detected keypoints are passed onto machine learning and deep learning classifiers for classifying the human actions. Experimental results demonstrate that multilayer perceptron and SVM outperformed all the other classifiers by reporting an accuracy of 87.80% and 87.77% respectively whereas LSTM did not produce very good results as compared to other classifiers. Stacked Long Short-Term Memory networks (LSTM( produced an accuracy of 71.30% and Bidirectional LSTM yielded an accuracy of 76.04%. The results also indicate that machine learning models performed better than deep learning models. The major reason for this finding is the lesser availability of data and the deep learning models being data hungry models require a large amount of data to work upon. The paper also analyses the failure cases of OpenPose by testing the system on aerial videos captured by a drone flying at a higher altitude. This work provides a baseline for validating machine learning classifiers and deep learning classifiers against recognition of human action from aerial videos.
A Novel Codebook Generation by Smart Fruit Fly Algorithm based on Exponential Flight
Authors: Kilic Ilker
Published: June 2023

A codebook is a combination of vectors that represents a digital image best and very useful tool for compression. Besides the well-known techniques such as Linde-Buzo-Gray, C-Means, and Fuzzy C-Means the nature-inspired metaheuristic algorithms have also become alternate techniques for solving the codebook generation problem. Fruit Fly Optimization Algorithm (FFA) is a simple and efficient algorithm, but the capturing of an agent by a local minimum point is the main problem. Therefore, the fruit flies generally do not reach the global solution at the end of the iterations. In this study, the FFA is empowered with a smart exponential flight approach to finding out a global optimum codebook. In this approach, if a fruit fly agent is captured by a local minimum point accidentally, the smart exponential flight steps provide an opportunity to escape from it easily. In the experimental studies, successful compression results have been taken in terms of lower error rates. The numerical results prove that the proposed Smart Exponential flight-based Fruit Fly Algorithm (SE-FFA) is better than the variations of convolutional FFA by providing a global optimum codebook.
Exact Algorithm for Batch Scheduling on Unrelated Machine
Authors: Allaoua Hemmak
Published: June 2023

In this paper, we propose a new linear algorithm to tackle a specific class of unrelated machine scheduling problem, considered as an important real-life situation, which we called Batch Scheduling on Unrelated Machine (BSUM), where we have to schedule a batch of identical and non-preemptive jobs on unrelated parallel machines. The objective is to minimize the makespan (Cmax) of the whole schedule. For this, a mathematical formulation is made and a lower bound is computed based on the potential properties of the problem in order to reduce the search space size and thus accelerate the algorithm. Another property is also deducted to design our algorithm that solves this problem. The latter is considered as a particular case of RmCmax family problems known as strongly NP-hard, therefore, a polynomial reduction should realize a significant efficiency to treat them. As we will show, Batch BSUM is omnipresent in several kind of applications as manufacturing, transportation, logistic and routing. It is of major importance in several company activities. The problem complexity and the optimality of the algorithm are reported, proven and discussed.

Gebelerin %88,3’üne acil cerrahi yapıldı. Ortalama hastanede kalış süresi 3,3±3,2 gün, doğuma kadar geçen ortalama hafta 21,1±8,6 idi. Gebelerin ortalama doğum haftası 37,8±2,8 idi. Acil cerrahi yapılan hastalarda laparotomi tercihi laparoskopiye göre anlamlı olarak yüksek bulundu (P=0.007). Laparotomi(LT) ve laparoskopi(LSK) grubunda gebelik sonuçları ve neonatal sonuçlar açısından fark saptanmadı.

Sonuç: Gebelikte geçirilen non-obstetrik cerrahi olumsuz gebelik ve neonatal sonuçlarda artışa yol açtığına dair bir sonuca ulaşılamamıştır. Ayrıca cerrahi şeklini değerlendirdiğimizde; laparotomi ve laparoskopi yapılan gruplar arasında gebelik ve neonatal sonuçlar açısından anlamlı bir fark bulunmadı. Bu konuda daha geniş çaplı çalışmalara ihtiyaç vardır.

P.A.Sorokin (1889-1968) tarafından yazılan ve Mete Tunçay tarafından çevrilen eser, Bilgi Yayınevi tarafından 1972’de Ankara’da yayınlanmıştır. Eser, toplumsal ilerleme ve tarih üzerine en canlı modern felsefeleri bütünlük içinde sunar. Yazar; son yüzyılın ileri gelen sekiz tarih felsefecileri olan A. Toynbee, O. Spengler, N. Danilevski, A. Schweitzer, F.S.C. Northrop, N. Berdyaev, A. Kroeber ve W. Schubart’ı ayrı ayrı inceler, kuramlarını çözümler, kuramları birbirleriyle ve kendi tarih felsefesiyle karşılaştırır, böylece kuram sayısı dokuza çıkar. Oldukça güç bir işe girişen Sorokin’in çalışması üç ayırımdan oluşur:1-Modern toplum felsefelerinin ana çizgileri, 2-Modern toplum felsefelerinin karşılaştırmalı ve eleştirici olarak çözümlenmeleri, 3-Geçerli bir toplum felsefesine doğru.

Sorokin, yukarıda adı geçen tarih felsefecilerin kuramlarını eleştirili olarak inceler. Sekiz tarih felsefecisinden üçünü bir grup halinde ele alır. Bunlar; Danilevski, Spengler ve Toynbee’dir. Sorokin’in karşılaştırdığı açılar şunlardır: Uygarlıklar kültür kümeleri midir, birleşmiş sistemler midir? Kültür ya da uygarlıkların doğumu, büyümesi, gelişimi, çözülmesi, ölümü, ömür süresi, yaratıcı etkenler, uygarlığın yaşam ve yaratıcılık devrelerinin tek veya çok oluşu, yaratıcılık merkezlerinin değişmesi problemleri. İkinci grup tarih felsefecileri; Northrop, Kroeber, Schubart, Berdyaev, Schweitzer’dir. Burada; kuramsal ve estetik kategoriler, felsefenin bilime bağımlı olup-olmaması, adı geçen felsefecilerin kuramlarının eleştirisi yapılır. Sorokin, adı geçen felsefecilerin kuramlarının haklılığını kabul eder ve sonra kendi modelini ortaya koyar.
Hz. Osman Yönetiminin Muhaliflere Karşı Tavrı: Ebû Zer Örneği
Authors: ARSLAN İhsan
Published: June 2023

Bu araştırmada Hz. Osman’ın yönetim anlayışına muhalif olan Ebû Zer’in eylemleri temel İslâm Tarihi kaynakları çerçevesinde bilimsel araştırmalara özgü metodolojik bakış açısıyla işlendi. Yapılan incelemede ilk Müslümanlardan olan ve kabilesinin İslâm’a girmesinde önemli rol oynayan Ebû Zer’in Medine’ye hicret ettikten sonra Hz. Peygamber’in burada kendisine verdiği görevleri başarıyla yerine getirdiği, Resûlullah’ın vefatından sonra Hz. Ali’nin halife olmasını istemesine rağmen ilk üç halifeye biat ettiği, ilk iki halife döneminde ise yönetimi eleştirmediği ve sakin bir hayat yaşamayı tercih ettiği belirtildi. Ancak onun, Hz. Osman döneminde idarenin gereksiz harcamaları ve bazı insanların mal biriktirme eğiliminde olmalarından dolayı Tevbe sûresinin 34. ve 35. âyetlerini merkeze alarak sistemi eleştirmeye başladığı, bu eleştirileri iktidarı için tehdit olarak algılayan Şam valisi Muâviye b. Ebî Süfyân’ın onu Medine’ye sürgüne gönderdiği, fakat Halife’nin uyarılarına rağmen burada da yönetimi eleştirmeye devam ettiği için Rebeze’ye sürgüne gönderildiği neticesine ulaşıldı.
Turizm Rehberliği Mesleği İçin Bir Uzmanlaşma Önerisi: Engelli Turist Rehberliği
Authors: ŞENGEL Ümit , KARAMANLIOĞLU Nazife
Published: June 2023

Amaç ve Önem: Çalışmada engelli turist rehberliğinin turizm rehberliği mesleği için bir uzmanlaşma önerisi olarak sunulması amaçlanmaktadır. Özel gereksinimli grupların seyahat etme taleplerine uygun cevap verebilecek rehberlerin olması gerekmektedir. Bu nedenle bu insanların özel gereksinimlerine göre farklı alanlarda eğitim alan rehberlerin mesleklerinde rekabet avantajı elde edecekleri düşünülmektedir.

Yöntem: Çalışmada nitel araştırma yöntemlerinden yararlanılarak saha araştırması süreci gerçekleştirilmiştir. Veri toplama aracı olarak odak grup görüşmesi kullanılmıştır. Veri toplanacak grup işitme engelli bireylerle ilgili konferans ve işaret dili eğitimi esnasında belirlenmiştir. Toplam 9 kişiden odak grup görüşmesi yöntemiyle veriler elde edilmiştir. Veriler MAXQDA programı kullanılarak içerik analize tabi tutulmuştur.

Bulgular: Elde edilen sonuçlara göre rehber adayı katılımcılar engelli turist rehberliğinin turizm rehberliği mesleği için bir uzmanlaşma alanı olabileceği konusunda görüş birliğine sahiptir. Duyarlı bir görüntü sergilemekte olan katılımcılar bu konuda uzmanlaşmanın ekonomik getirilerinden ziyade sosyal sorumluluk ve farkındalık gibi amaçlarla gerçekleşmesi gerektiğini ifade etmektedir. Ayrıca turizm rehberlerinin bu konuda uzmanlaşmalarını belirleyen esas unsurun kişilik özellikleri olduğu sonucu ortaya çıkmıştır.

Özgünlük/Bilimsel Katkı: Bu çalışma, engelli bireylerin sahada (müze ve ören yerleri) yapacakları seyahatleri kolaylaştırmak amacıyla engelli turist rehberliğinin turizm rehberliği mesleğinin bir uzmanlaşma alanı olarak öneren literatürdeki önemli çalışmalardan biridir. Konu özel gereksinimli grupların hayatın her alanında olduğu gibi, müze ve ören yerlerindeki seyahatlerde de kendilerini rahat hissetmeleri ve kaynakları eşit paylaşmaları gerektiği düşüncesinden hareketle gerçekleştirilmiştir.

Sınırlılıklar: Çalışma işitme engeli konusunda bir tanıtıcı konferans ve temel düzeyde işaret dili eğitimi verildikten sonra gerçekleştirilmiştir. Bu nedenle engelli bireyler konusunda önemli bir farkındalığı ortaya koymakla birlikte, tek bir özel gereksinimli grupla sınırlıdır.

Uygulanabilirlik: Son yıllarda özel gereksinimli gruplarla ilgili olarak özellikle konaklama tesisleri bağlamında yapılan çalışmaların turizm endüstrisindeki diğer tüm alanlara yayılması önemli bir ihtiyaçtır. Seyahat acentalarının özel turlar tasarlayarak bu insanların turlara katılmalarına imkân sağlamaları ve turizm rehberlerinin ise konuyla ilgili özel eğitim alarak uzmanlaşmaları önerilmektedir.

The ministry work in the Church presupposes the involvement of all the faithful in the liturgy of the Church. Women have an important role in the Church’s liturgy, namely lectors and acolytes. This article discusses the role of women in the liturgy in the Church in Flores - NTT which is dominated by patriarchal culture. This study uses a qualitative phenomenology method to explore the meaningfulness of the theme from the women’s perspective. There were 21 respondents consisting of women who work as lecturers and IFTK Ledalero students. The result of the study show that gender bias due to the influence of patriarchal culture does not prevent women from participating in the Church’s liturgy. Even though they do not have a legal umbrella yet, the Church in Indonesia especially in Flores, has open up opportunity for women to be involved in the liturgy. Pope Francis' action to amend the canons of canon 230 § 1, is an act of respect for women, specifically the role of women in the liturgy of the Church. Even though the pope's actions can be considered too late for the context of the Church in Indonesia, the impact of this decision has made the women of NTT, especially in Flores, who are members of the Church, increasingly believe in the struggle to present a better world from the reality of male domination in cultural and social life. church today that feels established and comfortable
