Authors: Brehm Lars , Günzel Holger , Humpe Andreas
Published: July 2021

Teaching sustainability presents challenges due to the inherent complexity and required behavioral change. A special pedagogical approach is needed. In this paper, we focus on the research question how students' awareness of sustainability issues can be improved significantly in a brief workshop. The presented workshop let the students autonomously addressing problems and possible solutions in small groups – with no patented recipes given, nor any "finger-pointing" from the outside. The educational basis for this workshop is the concept of discovery learning in combination with sketchnoting. This is especially appropriate to present acquired knowledge in a compact and meaningful way, to show relationships and allow schemas to be developed by the participants. This paper also describes the workshop results from several executions and the lessons learned.

Authors: Ibrahim Walid , Amer Hoda
Published: July 2021

Learning Outcomes Assessment (LOA) provide educators with a practical instrument to review and enhance the alignment between the planned, delivered and experienced curriculum. Effective LOA processes help educators decide on the proper actions to take and the strategies to implement in order to ensure the continuous improvement of the student learning experience, and the attainment of the intended learning outcomes. Nonetheless, the adoption of LOA in higher education is still lagging and the assessment loop is rarely closed. This is mainly due to the indigent implementation of the assessment processes, and the vague definition of the responsibilities and quality assurance measures. This paper introduces a committee infrastructure to foster accountability and responsibility and assure the quality of the implemented assessment processes. The infrastructure has been established syccessfully over the last few years, and a noticeable improve in the execution of the assessment process has been detected.

Innovation is becoming a fundamental part of many sectors and environments, including universities, not only regarding their research but also how education is approached. In this line, one of the ways to achieve these objectives is based on a collaboration between society, which presents a need to be solved, and the University. This society-university integration is achievable via the Service-Learning methodology (SLM), which has always been based on establishing strong links between the educational world and society. This paper presents a SLM-based project linked to technological development for the health sector during the SARS-CoV-2 pandemic. Specifically, undergraduate chemistry students, and Ph.D. students led by professors have presented part of their technological developments to people in society who are at risk of exclusion to help them understand aspects of infection as well as diagnosis of diseases. In short, the objective is to transfer in an enjoyable fashion, a set of technological developments and knowledge that can help society understand aspects related to the COVID-19 pandemic.

Published: July 2021

This research examines the attitude of faculty lectors, Information Technology students (IT) and humanitarian students (HS) towards the aspects of forced distance learning (DL) due to Covid-19. About 70% of the surveyed IT students and 50% of HS believe that DL can fully replace face-to-face classes and completely switch to DL, about 70% of lecturers have the opposite opinion. At the same time, IT had a 4.5 times higher chance of a positive attitude towards the transition to DL than HS. The majority of all respondents consider that their own notes are important and that classroom learning is better than online. At the same time, among IT that are ready to switch to DL, 69.03% believe that the perception of educational material is better in the classroom. Fewer IT students (30.1%) than HS (68.2%) and lecturers (100%) consider that printed textbooks are important. About 70-90% of students consider that the following DL disadvantages are important: communication difficulties, cocial isolation, the need of self-discipline and self-motivation and fears that the employer will not appreciate the knowledge gained from DL. For the majority of IT, lack of student events is significant, and for the majority of HS,
Adapting your teaching during the pandemic? How social science research education adapted to the COVID-19 pandemic
Authors: Prandner Dimitri , Hasengruber Katrin , Forstner Matthias
Published: July 2021

University lecturers worldwide had to adopt to online teaching at very short notice due to restrictions related to COVID-19. This is a particular challenge for social sciences research methods education, which often requires face-to-face interactions. Data from an online survey of lecturers (n = 105; March 2020) who teach social science methods and methodology at Austrian public universities was used to discuss their adaption behavior and the corresponding determinates. Consequently, a measure for the rate of adaption of teaching materials and methods per lecturer was constructed and a linear regression model employed to discuss the determinants of this adaption. The results show the following: Understanding online teaching as a permanent solution for the future, the extent of an individual’s teaching load and a tenured employment were identified as significant influences fostering the adaption of teaching methods and materials to the online context. The predictors discovered differ from previous studies, and it has to be assumed that the adaption behavior in the wake of the pandemic had a profound impact on the ongoing digitalization of university education.

Authors: Leal Fonseca Diego Ernesto , Vargas Betancur Ana María , García Pineda Leydy Johana
Published: July 2021

Mentoring programs in higher education have gained importance in recent years for their contribution to the development of professional and personal skills, as well as improving student retention and completion. Considering this, the program Generation E, –created by the Colombian Ministry of Education to provide socioeconomic support to underprivileged youth for their access to higher education–, started to include mentoring strategies in 2019 as a key element to foster completion. In 2020, a development model was designed to assess the situation of these programs in higher education institutions across the country. This article describes an analytic tool –called DIADEMMA (Diagnosis of Mentoring Moments Development)– which articulates five development moments with six factors key to any mentoring program, drawing on a structure proposed by an existing model for the assessment of higher education programs for student retention in Colombia. The first implementation of DIADEMMA allowed to identify the status of peer-mentoring initiatives in an initial group of institutions, providing input to define actions to support their consolidation, considering the nature and possibilities of each one of them.
Global Competency Through Collaborative Online International Learning (COIL)
Authors: Harris Jessica M. , Seo Minjung , McKeown Joshua S.
Published: July 2021

AbstractThere is a need for college students to develop global perspectives and gain cultural awareness to become responsible global citizens. Innovative ways to create such experiences are known as Collaborative Online International Learning (COIL experiences). COIL is a voluntary partnership between professors in different countries collaborating on jointly-constructed learning experiences to enhance international and intercultural understanding. The purpose of this article is to highlight a successful COIL partnership between students from SUNY Oswego in New York and The Hague University of Applied Sciences in the Netherlands during the COVID-19 pandemic. 35 students participated in the experience that served as a platform to educate students through a health educator’s unique cultural lens. Benefits from the experiences regarding global outcomes showed that both US students (n=70.6%) and Holland students (n=61.1%) felt that they gained the appropriate skills and knowledge to use in their future careers. 70.6% of US and 61.2% of Holland students reported that the COIL experience introduced them to a new outlook and new ways of thinking about how they relate to the world. The current COVID-19 pandemic has created an opportunity to rethink education pathways and integrate global learning in our classrooms.Keywords: Global learning; COIL; Partnerships, Collaboration
Promoting Inclusive Practice: Video CVs as a Teaching & Learning Tool in the Language Classroom
Authors: Wood Jennifer
Published: July 2021

This paper considers the benefits and results of the introduction of a video CV assessment into an intermediate, mixed-ability undergraduate Spanish-language class. This task was designed both to modernize an existing written task and to provide students with dyslexia and other language-processing difficulties with the opportunity to best display their capabilities in the second language (L2). Dyslexia is a Specific Learning Difference (SpLD) whose characteristics can vary in form and severity, but which particularly affect language-processing. Dyslexic individuals often display a “paradoxical co-existence of special abilities and disabilities” (West, 1991, p.32): Abilities which include verbal acuity, visuospatial faculties, flexible problem-solving and creative skills which can all be used to advantage when designing activities to help students achieve success in learning a second language. A multisensory approach is now widely recognised as benefiting dyslexic individuals while other suggested adjustments include: oral recordings rather than written performance; multimedia presentations; and the incorporation of tasks that activate kinaesthetic-tactile components of learning, all elements mobilized within the video CV task. The video CVs produced by students were multisensory and creative while effectively mobilisiing the L2, showing the benefits of inclusive practice for all students, helping to create a diverse and engaging learning experience.
The Virtual Shoe Salon: A creative and active approach for teaching research and data analysis to fashion students
Authors: Braithwaite Naomi Joanna
Published: July 2021

The push towards creative and active learning in higher education has gained momentum in recent years, creating opportunities for innovative, student focused approaches. The Covid-19 pandemic shifted the educational landscape to the online world, propelling the need to create compelling learning activities for students. While also fostering a sense of community and facilitating both peer relationships and peer learning. This paper presents the development and initial implementation of an innovative teaching tool, The Virtual Shoe Salon, which is based on creative pedagogies and experiential learning. The Virtual Shoe Salon has been implemented to embed stronger skills in research and data analysis within the curriculum of our fashion business courses. As a teaching method it can embrace both online and face to face environments. Drawing from a theoretical foundation of material culture, combined with an adaptation of the photovoice research approach, this salon takes the ordinary, but expressive objects of shoes to engage students in research and analysis through collaboration, conversation and peer to peer learning.  The paper presents the rationale for the Virtual Shoe Salon, and findings from its implementation with 250 students. Subsequent evaluation and reflection with both students and staff have evidenced the positive role of the Virtual Shoe Salon in facilitating active and collaborative learning around research and data analysis. While it has actively encouraged a dynamic and collaborative learning environment, the Virtual Shoe Salon has initiated a shared space underpinned by the sense of community and belonging for students that Covid-19 had eroded .

Analogy-based Instruction for Effective Teaching of Abstract Concepts in Computer Science
Authors: Gupta Gopal , Saxena Pawan , Singh Sanjay K.
Published: July 2021

In the analogy-based learning method we map a concept that is being learned to a well-understood concept. An analogy is mainly useful when learners lack prior knowledge of the topic being learned. Computer Science (CS) is a subject whose concepts tend to be highly abstract and therefore difficult for undergraduate students to understand. Analogy-based instruction can greatly reduce a student’s burden of learning these abstract CS concepts. Role of analogy in teaching CS topics has not been adequately explored. In this paper we discuss analogy-based instruction in computer science and its advantages. Over the last decade we have developed analogies for a large number of difficult CS concepts and extensively used them in the classroom at our institution. We list these analogies and as an illustration discuss one of them (from the subfield of operating systems) in detail. We also present the evaluation of our analogy-based instruction method. Our results indicate that our techniques are quite effective in improving student learning outcomes.

Authors: Ramirez Mario , Ruiz Olga
Published: July 2021

The transition from traditional teaching to virtual teaching in public institutions of higher education (PIHE) is a process that began with the first computers in the 20th century, which has been accelerated by the Covid 19 pandemic, forcing the PIHE to adopt new virtual learning environments for which the traditional educational model was not designed at the University of San Carlos de Guatemala (USAC). The global characteristics of the Covid 19 pandemic have affected USAC, who had to adapt various methodologies with the support of ICT to continue the educational process. The implementation and use of these technologies evidenced a digital divide both in cognitive processes and in the use and access of digital tools. The study addressed the trends of use and access to technology in three case studies at the campus of USAC in Guatemala City: Architecture, Humanities and Economic Sciences, with a sample of 2,128 students, who responded through a Google form survey instrument, interviews and a forum, from February to may 2020. The results are that different socioeconomic levels affect the access and use of technology for the educational process, which is why it is necessary for PIHE to adopt policies and strategies that guarantee education.

Published: July 2021

Technology has created a vast array of educational tools readily available to educators, but it also has created a shift in the skills and competences demanded from new graduates. As data science and machine learning are becoming commonplace across all industries, computer programming is emerging as one of the fundamental skills engineers will require to navigate the future and current workplace. It is, thus, the responsibility of educational institutions to rise to this challenge and to provide students with an appropriate training that facilitates the development of these skills. The purpose of this paper is to explore the potential of open source tools to introduce students to the more practical side of Smart Maintenance. By developing a learning pilot based mainly on computational notebooks, students without a programming background are walked through the relevant techniques and algorithms in an experiential format. The pilot highlights the superiority of Colab notebooks for the remote teaching of subjects that deal with data science and programming. The resulting insights from the experience will be used for the development of subsequent iterations during the current year.

Authors: Hogue Lindsey B. , Bleak Kenneth , Abernathy Tammy
Published: July 2021

This project used psychosocial mentoring (Curtin et al., 2016) to create a collaborative mentoring experience prepare doctoral students to become the instructors of record. In the collaborative mentoring experience, we paired doctoral students with a faculty member teaching a class that the doctoral student aspired to teach. The doctoral student observed the faculty member teaching, engaged in discussions with the faculty member, and reflected on the process. The following semester, the doctoral student became the instructor of record for the course. Following this experience, two doctoral students and one faculty member completed a retrospective self-study through journaling and discussions. After analyzing the results through discussions, we identified three themes: (1) understanding the course and our learners, (2) underlying goals and processes involved in college teaching, and (3) stretching the scope of practice for instructors of record. This paper describes the theme of stretching the scope of practice for instructors of record. Implications for teaching and learning in higher education are discussed.
How it started/ how it’s going’: Aligning Teacher Educators’ designs, approaches and identities in our new online reality
Authors: Charbonneau-Gowdy Paula , Pizarro Jaime , Salinas Danisa
Published: July 2021

E-learning scholars have long predicted the conversion of conventional education to online learning spaces. That conversion has now happened. Regardless of what occurs in a post-pandemic era, teaching and learning will never be the same. Where does that leave teacher educators (TEs) who grapple with how to best prepare future teachers for the new era? The aim of our research was to determine the impact of supporting a small group of Chilean TEs in re-designing their online instructional approaches by aligning them with contemporary learning theories and goals. In the Chilean context, prior to the pandemic, e-learning was still on the periphery, and transitions from teacher-directed approaches had only just begun. In this 10-month qualitative inquiry, we focused on the TEs experiences online as they adopted sociocultural-based, 21st century instructional designs, and implemented strategies intended to promote agency and engagement in their students. The TEs long-held teacher-centric identities and approaches sometimes interfered in this trajectory. Yet, their heightened critical awareness of the ineffectiveness of traditional teaching paradigms in online settings combined with their grounded efforts and perseverance, resulted in positive evidence of ‘real’change to their designs, practices and identities – changes many have been seeking in educational systems for some time.

The SocialNEET project, promoted at the Polytechnic Institute of Bragança, between November 2020 and February 2021, whose main goal is the (re)integration in the labour market of young people, through the creation of innovative social business solutions and finding employment in companies or associations in the social sector. It provides learning for active life and education for entrepreneurship, through the participation of facilitators (students of higher education) who will simplify the connection between mentors (successful entrepreneurs and consultants) and young NEET (not in education, employment or training), in the sense of creating life projects, social projects or innovative social business and job search solutions in companies or associations in the social sector. The essential focus of this article corresponds on the training of facilitators (N=10) and its objective is to understand the capacities developed by them in this process, as well as the limitations felt and the strategies to minimize them. For this purpose, a qualitative case study was carried out based on the documentary analysis of the training, namely an observation grid, a questionnaire to the trainees and the reflective analysis of the trainers. We conclude that the strengthening of soft skills, intercultural communication and education for entrepreneurship may be the priority ways to promote social improvements and thus contribute to the 2030 Agenda.
Online teaching and learning: a year later what has changed?
Authors: Gonçalves Vitor , Gonçalves Bruno
Published: July 2021

The world is currently experiencing the covid-19 pandemic that has been going on for almost a year and which has transformed the way of carrying out the economic activities that support contemporary societies. The education sector is precisely an example of this abrupt change. The face-to-face teaching-learning process was converted to an online format, so students, teachers, schools and families had to adapt immediately to this transformation. There was no time to provide schools and persons with digital equipment and tools, nor with educational agents for training oriented to the practice of online teaching. Everyone had to do their best, adapting, learning autonomously and with their peers and solving their own problems. This research was developed with the support of the case study methodology in a Portuguese educational institution and aims to understand, through the Dynamic Digital Competence Reference Framework (DigComp), the evolution of students in terms of digital skills in the period of the covid-19 pandemic. The results show that students acquired a set of digital skills that allowed them to participate and interact with stakeholders in the online teaching-learning process. In addition, a set of suggestions is also presented for the acquisition or improvement of other students' skills.

Published: July 2021

In this article I will apply an intertextual perspective to a selection of epigrams from the Greek Anthology in order to assess the role of variation within these epigrams. Within the tradition of the literary epigram, the element of variation had always been important, yet some Hellenistic and Imperial epigrammatists, such as Archias and Zosimus, took this dimension of the genre to extremes, in creating strings of epigrams which intentionally vary on their Imperial models and on their Imperial models´ Hellenistic models. This article charts some of these epigrammatic ‘chain reactions’: the poems on the three hunting brothers Damis, Clitor and Pigres, the birthday epigrams of Leonides of Alexandria, the epigrams on the shipwrecked Antheus, and several epigrams on ships that were destroyed prematurely. All serve to assess the way in which intertextual processes develop within the epigrammatic tradition, and to show that such a perspective is essential to their appreciation.

Development of a geometric slip flat model when turning a vehicle with two steering axles
Authors: Malinovsky M. P.
Published: July 2021

Introduction (problem statement and relevance). One of the main stages in the design ofspecial purpose vehicles is the calculation of the steering control. At that, engineers are guided by anumber of regulatory documents that lack one of the most important requirements, which is to minimize tire lateral deviation. The author notes the lack of scientific research in the field of geometric slip, which is caused by the non-compliance between the actual angles of wheels rotation and the calculated values for pure rolling and is an inherent property of any traditional steering linkage.

The purpose of the study was to develop a mathematical model of the steering drive of a special-purpose vehicle with two steering axles to assess the geometric and power slip.

Methodology and research methods. There is a known method for calculating the steering drive using trigonometric expressions, in particular the cosine theorem. The author proposed to use the coordinateiterative method developed by him and based on the equation of the sphere, with the steering wheel rotation angle in the kinematic calculation of the steering drive as a differentiation step. The choice of the steering drive parameters according to the conditions of symmetry and minimization of slip was carried out by the method of multivariable optimization.

Results. In the course of the research, it was found that the choice of the characteristic of geometric noncompliance was a multi-parameter task, and changing one parameter led to the necessity of adjusting the others. If it was not possible to achieve zero geometric slip for all steered wheels, the task of optimizing the steering drive parameters wasreduced to minimizing geometric or total slip. The value of the slip essentially depended on the selected differentiation step. When choosing the characteristic of geometric slip, it was necessary to observe the condition of the steering linkage symmetry when turning left and right. When the wheels were turned from the neutral position to the periphery, the power and geometric slip compensated each other, which led to the decrease of the total slip and tire wear.

The scientific novelty of the work lies in the development of a geometric slip model for a vehicle with two steerable axles, including a spatial model of the steering drive which allows to evaluate the influence of the geometric slip on the turn kinematics, as well as the mutual influence of geometric and power slip in order to select the steering drive optimal parameters of the multi-axle vehicle from the viewpoint of minimizing tire wear during curvilinear motion.

Practical significance. The research results must be taken into account in the development of steering drive and turning control systems for multi-axle special-purpose vehicles, including them in the educational process as well.

Cloud computing is a technique for storing and processing data that makes use of a network of remote servers. Cloud computing is gaining popularity due to its vast storage capacity, ease of access, and diverse variety of services. When cloud computing advanced and technologies such as virtual machines appeared, virtualization entered the scene. When customers’ computing demands for storage and servers increased, however, virtual machines were unable to match those expectations due to scalability and resource allocation limits. As a consequence, containerization became a reality. Containerization is the process of packaging software code along with all of its essential components, including frameworks, libraries, and other dependencies, such that they may be separated or separated in their own container. The program operating in containers may execute reliably in any environment or infrastructure. Containers provide OS-level virtualization, which reduces the computational load on the host machine and enables programs to run much faster and more reliably. Performance analysis is very important in comparing the throughput of both VM-based and Container-based designs. To analyze it same web application is running in both the designs. CPU usage and RAM usage in both designs were compared. Results obtained are tabulated and a Proper conclusion has been given.

Summary. Modern medicine widely uses artificial materials to replace damaged tissues and organs. Biodegradable implants should be gradually replaced with living tissue and stay functioning within a specified period, don’t have any negative impact on surrounding tissues and a human body in general. Clinical studies of biochemical values specifying the intensity of inflammatory response to IM nailing with biodegradable implants are of clinical and scientific interest. Task of the study: to substantiate of the use of implants made of biodegradable magnesium alloy MS-10 in the dynamic IM nailing for diaphyseal fractures of the tibia. Materials and methods. The study involved 34 patients with diaphyseal tibial fractures, which resembled surgical treatment (IM nailing). Cannulated intramedullary titanium nails served as a blocking pin. The treatment included closed reposition followed with IM nailing of a tibia. To lock the nail, a screw made of magnesium alloy MS-10 was inserted in a static (round) hole in 16 patients. In 18 patients, a screw made of titanium was inserted into a static hole. The both groups passed blood sampling for studies, before and after the surgery, 2 and 4 weeks, 2 and 4 months after surgery. Biochemical blood tests were to determine the concentration of fibrinogen-monomer complexes in the blood plasma (β-naphthol test). Results. The study of the activity of AST and ALT found it lower (19 and 29%) in patients with biodegradable screws, compared to the group of patients with IM nailing locked with bioinert screws. The situation was similar with ESR, fibrinogen B and total bilirubin in the blood of patients in both groups. Conclusions. The study convincingly proves the expediency of the use of biodegradable material (magnesium alloy MS-10) to produce implants for the IM nailing for the patients with long bones’ fractures.

Resume. In the structure of complications, pain syndrome, which is not associated with instability of the components of the endoprosthesis or infection, remains a serious problem due to difficulties in diagnosis and treatment. The cause of residual pain may be the presence in the patient of discogenic radiculopathy or spon-dylolisthesis of the lumbar spine. The aim of the study. To determine the role of discogenic radiculopathies and spondylolisthesis of the lumbar spine in the structure of pain after hip arthroplasty. Materials and methods. A sample and retrospective analysis of case histories of 138 patients with hip and lumbar syndrome, who under-went hip arthroplasty in the clinic of orthopedics and traumatology of adults SI "ITO NAMS of Ukraine". All patients were examined clinically and radiologically. Additionally, all patients were examined by a neurolo-gist to determine the neurological status of patients, diagnosis. Evaluation of the effectiveness of treatment of patients with residual effects of discogenic radiculopathy and spondylolisthesis after hip arthroplasty was performed on the functional scale of Oswestry. Results. The analysis of the patient database revealed a statisti-cally significant (p≤0.05) predominance of patients with the presence of disc herniation at the level of L3-L4 and hypolordosis. The survey revealed 9 cases of discogenic radiculopathy and 6 cases of spondylolisthesis in patients with PD, which amounted to 6.5% and 4.5% of the total number of examined patients. The high effi-ciency of the developed treatment-and-prophylactic measures in patients with discogenic radiculopathy or spondylolisthesis and lumbar-lumbar syndrome has been determined. Timely appointment of complex conserva-tive and operative methods allowed to achieve satisfactory results in 100% of cases. Conclusions. Studies to determine the role of discogenic radiculopathy and spondylolisthesis of the lumbar spine in the structure of pain after hip arthroplasty will contribute to the further development of clinical, diagnostic and treatment algorithms for patients with hip and lumbar syndrome.

This study was designed to evaluate the effects of different Marshal breed broiler on hatching egg weights on hatching characteristics and post-hatch performances; and also to compare the cost of production of hatchlings to table size. A total of 900 hatching eggs (HE) from 40 weeks old parent stock were sorted, graded and purposively grouped on weight basis into small (<50g), medium (50-65g) and large (>65g) sizes (3 groups). Each group was allotted 300 eggs and replicated thrice, with each replicate having 100 eggs in a complete randomised design before incubation for 21 days. Candling of incubated eggs was done on day 18 on group basis and numbers of fertile eggs noted. The chicks were individually weighed and counted to determine hatchability, hatchling weight and cost of production. Thereafter, hatched chicks were allotted into the respective groups and replicated to determine the post-hatch performance. Each replicate has 45 chicks, intensively raised and were fed ad libitum with broiler starter mash for the first 4 weeks of life and broiler finisher mash from 4-8 weeks. Data generated include feed intake, final weight, mortality; weight gain, feed conversion ratio and unit cost of production of chicken were calculated. The data were analyzed by GLM of SAS and Duncan’s multiple-range test was used to separate significance of differences among treatment means at 5% significance level. The medium HE had the best fertility (93.00%), hatchability (95.67%) and cost of producing a chick (N 90.07) when compared with the small and large HEs. The large HE has the best results in terms of, final weight and weight gain, while medium HE has the best FCR, lowest mortality and least cost of production, which are significant at p< 0.05. It is therefore recommended poultry breeders and hatchery operators should consider the use of medium weight (50-65g) HEs in their operations, so as to cut down the production cost.

This experiment was designed to determine the meat quality and lipid profile of broiler chickens fed diets containing turmeric (Curcuma longa) powder (Tur) and cayenne pepper (Capsicum frutescens) powder (Cay) as antioxidants. Two hundred and forty three (two-week old) Abor Acre broiler chicks were randomly allotted to nine treatment groups of 27 birds each, consisting of three replicates of nine birds each in a completely randomised design. Three levels of Tur (0, 2 and 4 g/kg) and three levels of Cay (0, 1 and 2 g/kg) were used to provide nine dietary treatments.  Meat quality indices such as cook and refrigerated losses, water absorptive power, etc were measured and determined at the 8th week. Broiler Chickens fed the basal diet had highest meat dry matter, protein content and least (p<0.05) meat pH, cook and refrigeration loss values. Meat triglyceride and meat malondialdehyde value was best (p<0.05) in treatments fed dietary 2 g/kg Cay, while chickens fed 2 g/kg Cay, 2 g/kg Tur + 1 g/kg Cay and 2 g/kg Tur + 2 g/kg Cay had better meat lipoprotein values. For meat sensory characteristic, meat flavour of broiler chickens fed diets containing 2 and 4 g/kg dietary Tur, were  moderately liked while overall flavour was best (p<0.05) in groups fed the basal diet with no dietary additive. It was evident in the study that the dietary inclusions of the test ingredients limited lipid oxidation, thus improved storage duration and meat flavor.

As a nation that is scientifically and technologically strong, the United States, which is called the world police, is certainly not an exaggeration. Public policies made by the United States are always loaded with economic interests. Regional domination framed by equal state relations on the basis of human rights has always been the entry point for the American nation in carrying out domination politics. Public policy made by the United States is certainly oriented to its interests. Naturally, the concept of the American nation Number one by its leaders has certainly made its global policy always oriented to its interests. In the current global arena, the United States of America always makes policies that benefit itself in this case its economic interests.
