Performance Analysis of Concrete Slab Reinforced with Steel and Bamboo
Authors: Surenthiran Iynkaran , Bogoda Sakura
Published: May 2022

Concrete and steel are considered the main construction materials in the world today while the cost of steel is rising year by year. Though steel can be recycled, it consumes a significant amount of energy in the manufacturing and recycling stages. Thus, to cope with that risk and reduce the building budget, it will be necessary to start using alternative resources. Studies were conducted to discover the appropriateness of using timber resources (e.g., Bamboo and Palmyra) to substitute steel as reinforcements in concrete. Bamboo is a quick-growing plant and is easily obtainable in the Asia region. Bamboo has a higher tensile strength than other timber resources and strength to weight proportion. However, due to its brittle behavior, bamboo cannot fully replace steel. Characteristics of bamboo differ with its time of life and class. The main aim of this research is to suggest a suitable hybrid reinforcement with steel and bamboo for the construction industry by analyzing the concrete slab element.  This paper discusses the behavior of concrete slabs, reinforced with steel and bamboo and the applicability of Finite Element Modelling (FEM) using the ABAQUS software. The numerical model was validated by the experimental investigation in the literature.

Published: May 2022

In the ornamental fish industry, there is a growing concern about the higher freight cost of feed ingredients. The present study aimed to cluster the locally available ingredients based on their nutrient contents, price, and availability.  A total of 15 ingredients; fish meal (FM), by-catches (BC), soybean seeds (Soy), maize (Ma), duckweed (DW), Azolla pinnata (Az), rice bran (RB), shrimp shells (SS), palmyrah fruit pulp (PFP), red seaweed (RS), wheat flour (WF), cassava flour (CF), cornflour (CoF), coconut copra waste (CCC), and groundnut cake (GNC) were selected as locally available ingredients. Principal Component Analysis (PCA) was performed by grouping the ingredients based on their nutrient contents, price, and availability using Minitab 16. In PCA, the two first components accounted for 57.50% of the total variance in the initial data. Protein, calcium, phosphorus, and price contribute positively with component 1, whereas carbohydrate content is related negatively to this component. Calcium and ash content correlated positively with component 2 and fat, gross energy, and availability were linked negatively to it. The PCA allowed the clustering the ingredients into four groups. Ingredients in Group 1, including Az, SS, RB, DW, and RS showed a positive correlation with component 2 and they contain more fiber although, they are not accessible throughout the year. Ingredients of Group 2, PFP, WF, CoF, and CF are excellent sources of starch but contained less protein content (0.94%, 11.00%, 0.00%, and 2.80% respectively). CCC, Ma, GNC, and SB pertain to group 3 correlating poorly with component 2. They are an excellent source of protein with the advantage that they are relatively affordable and easy to available than the other groups. Ingredients in group 4 incorporated BC and FB. Although they are high in protein, they are expensive and very poor in carbohydrates. Therefore, it is recommended that the ingredients in group 3 are the best choice for feed formulation with balanced nutrition at a low cost for fish feed preparation.
Effects of Crumb Rubber on the Shear Strength of Sand: An Experimental Study
Authors: Sung Brandon Hon Kong , Wong Soon Yee , Cyril Perpetua Aaniya , Lee Min Lee , Mohamed Abdullahi Ali
Published: May 2022

The application of waste rubber tires for ground improvement helps to improve the environment by recycling and reusing it as admixtures. This research aims to investigate the shear strength parameters of rubber-sand mixtures. By using crumb rubber with a constant size (425μm), the sand is replaced by different percentages (0, 2.5, 5.0, 7.5, and 10%) of crumb rubber by weight. A direct shear box test is used to determine the shear strength parameters of rubber-sand mixtures with two different controlled densities. The samples were loaded with normal stresses of 20, 40 and 80kPa and were sheared at a rate of 1mm/min. Although, this experiment discovered that crumb rubbers improve the shear strength parameters in loose sand, however, a reduction in shear strength parameters was found in dense sand. Moreover, it was observed that the inclusion of crumb rubbers into sand greatly improve the strain energy of both loose and dense sand. Likewise, rubber has a low unit weight which makes it suitable for lightweight backfill materials. The surface properties of rubber should be further studied to understand the contribution of shear strength in the rubber-sand mixture.

COVID-19 is prevalent in almost every corner of the globe, meanwhile Sri Lanka is also experiencing it.  Higher education providers of the department of agriculture (extension and training division) had to rapidly transition their teaching programs to online learning and assessment. The purpose of this study was to investigate the effectiveness of online learning during the COVID-19 period. Accordingly, students from four different schools of agriculture (Paranthan, Palamuna, Vavuniya, and Palwehera) were purposively selected (n=210). Google form was used to collect data. The results revealed that 53.3% preferred a combination learning system of both traditional learning and online learning. Advantages of online learning were the ability of recording lectures as video (51.7%) and learn in a comfortable place (42.1%).  With regards to the obstacles to online learning during the COVID-19 technical problems significantly (91.9%) affected learning while reduced interaction with their teachers/instructors (43.8%) and poor learning environment at home (39%) also were considerable barriers. There was a statistical difference (p<0.05) between face-to-face and online learning in terms increase knowledge, practical skills, social competencies, and assessment methods. However, successful implementation of online learning into the curriculum requires a well-thought-out strategy and a more active approach.
Health Consciousness and Attitude towards Preventive Healthcare in India – An Empirical Study
Authors: Menon S.R. , Jaffer N.M.
Published: May 2022

Health consciousness is about making health a priority, being aware of one’s health and any changes thereabout and a willingness to take actions that help in maintaining health. Preventive healthcare includes a gamut of measures that are taken to prevent illnesses and diseases that ranges from diagnostic medical practices to managing one’s lifestyle. The scales that are used to measure health consciousness and related concepts are developed and tested in the West and there is no such scale that fits the demographic and cultural context of India. The objectives of this study were to conceptualize a health consciousness scale that is relevant to the Indian context and to examine the influence of health consciousness on attitude towards preventive healthcare. This was a quantitative study that was carried out in India in June 2020. Sample size was 213. Items to be included in the scale were derived based on review of existing literature. Confirmatory factor analysis was used for data reduction. A series of principal component factor analyses using Varimax yielded 12 scale items that loaded onto 3 factors – health involvement, health responsibility and health awareness. Scale items were tested for validity and reliability - measures tested include Cronbach’s alpha, composite reliability, discriminant validity and AVE. Structural equation modelling was used to test the effect of these 3 factors on attitude towards preventive healthcare. It was found that all the three factors have a direct and positive effect on attitude towards preventive healthcare. This study has great implications for hospital managers. Health consciousness can be an effective segmentation variable in identifying target group for marketing preventive healthcare in India.

Harnessing Organizational Leadership and Cultural Competence to Attract and Retain Quality Teachers: The Case of Inner-City Schools
Authors: Ratican Sean , Miller Kenneth L. , Cripe M. Kathleen , Ratican Crystal , Miller Susan M.
Published: May 2022

Strategic investments in organizational leadership within the education sector can reap significant dividends in attracting and retaining quality teachers. These investments include comprehensive cultural competency training for all school administrators, teachers, and staff as well as the inclusion of these groups in creating a collaborative organizational culture. Such investments are particularly important in inner-city schools, where research reveals that cultural incompetence and the absence of a collaboratively developed organizational plan contribute to high levels of teacher attrition and substantial difficulties in attracting new teachers. Because scholarship has already recognized and identified the problem of attracting talented teachers to low-income and urban districts, this article takes the next step to suggest novel evidence-based solutions to the problem. Central to this approach is the school administrator’s responsibility to build an organizational culture that ensures equity, educational rigor, and opportunities for meeting teachers’ and administrators’ work-related needs. Building this culture requires (a) delivery of empirically supported cultural competency training; (b) self-assessments of management style to create an approach designed to enhance employee satisfaction; (c) creation of a shared vision and organizational leadership plan designed to make the work environment more attractive and satisfying to current and prospective teachers; and (d) development of a flexible yet practical service delivery framework that enables employees’ workplace needs to be met. In creating this culture, we argue that inner-city teacher attraction and retention rates can be dramatically improved.
A brief history of Canadian freeze-dried blood products: Ingenuity, collaboration, and leadership
Authors: Moore Marcus A. , Beckett Andrew
Published: May 2022

LAY SUMMARY

During the Second World War, Canada became a leader in the development and production of products used to treat shock, particularly shock caused by massive bleeds. Canada started the first blood service in response to the need for blood products overseas. This was done in the form of freeze-dried serum, which is made up of fluid-based proteins extracted from blood. Freeze-dried serum could be stored indefinitely and was lightweight, hardy, and easy to deliver both to the battlefield and to the patient. Freeze-dried serum could be provided to patients in shock as a result of losing a large volume of blood. Unfortunately, after the war, freeze-dried blood products fell out of favour over concerns about viral hepatitis. Recently, freeze-dried blood products have enjoyed a renaissance, and Canada is currently developing a new product to meet the challenges of remote resuscitation.

Authors: Mokhunko O. , Gavrilova N. , Mykhaylenko V.
Published: May 2022

Football is the most accessible, popular and popular means of physical education for modern youth. It was found that the more successfully the issue of morphofunctional development and motor training of students is solved, the more the physical condition and success in further play activities depend. It is established that along with learning techniques and tactics, this game has ample opportunities to increase the morphofunctional capabilities of student youth. As a result of long-term adaptation to physical activity in the process of playing football in the body of athletes are specific functional changes, supported by morphological and functional changes in body systems.

Improving the morpho-functional capabilities of students in the process of sectional football lessons is provided by directly influencing the development of general endurance, as this motor quality characterizes the functional state of the body and is most related to health indicators. The predominant use of special physical exercises aimed at improving the functionality of the circulatory and respiratory systems, conducting outdoor activities, high emotionality and variability of content to some extent increased the effectiveness of pedagogical tasks. At the same time, it is especially important to ensure constant and timely control over the effects of physical activity on the body of those involved. The issue of improving the health orientation of school physical education requires the search for improvement of the content and direction of physical exercises. It is known that the main form of physical education at school is a lesson in physical education. However, their number does not provide the necessary for the developing organism, the amount of motor activity and does not form in students a stable need for regular exercise.

The presented article considers the historical prerequisites for the development of aikido in Kherson. Despite the lack of research in this area, we were able to find out the date of the first section on aikido in Kherson, it is the 1996th year.

Speaking about the development of sports and the work of sports sections in Kherson in the 1990s, one must note that was a difficult period in the life of all the Ukrainian cities. As the collapse of the USSR and the beginning of the formation of Ukrainian statehood were associated with a huge shortage of basic livelihoods of common people. However, in contrast to the lack of material goods, there was an increase of interest in sports life, especially among children and youth. The sections on boxing, wrestling, judo, sambo wrestling, hand-to-hand combat, kickboxing, as well as martial arts, in particular karate, wushu, ninjutsu, taekwondo, etc., were especially popular.

This interest was further reinforced by the influx of films, magazines and television programs that broadcast pro- Western trends in the information space. According to the participants of these processes, there was a great desire among young men and women to study martial arts on a professional level, but there were no masters in Kherson or even in Ukraine. Foreign educational publications came to the rescue, which were self-translated, repeatedly copied by hand and studied; techniques were tested in practice, which was often accompanied by high injuries. Gradually, the flow of knowledge became more accessible and the understanding of techniques deeper, and even excellent masters, representatives of various schools started to come to Ukraine, and it became possible for our compatriots to learn directly from masters.

That is how in the second half of the 90s a group of like-minded people appeared in Kherson, who began their first steps in a completely new form of Japanese martial arts for this region – aikido. Often their interest and devotion to aikido was a real test, because they all developed and promoted aikido in Kherson exclusively at their own expense and often at the cost of their own health, but today we can talk about Kherson aikido thanks to the first masters who laid the foundations of the first dojos in Kherson.

Today almost all types of traditional martial arts are practiced, among which the disciplines of Budo and, in particular, aikido, occupy an important place in Kherson. This article discusses how the process of development and formation of lasting interest in this type of Japanese martial arts in Kherson took place, and what figures and masters are behind this process.

Modeling of training and competitive activity of athletes and reasons for a conflict of interest
Authors: Muntian V. S.
Published: May 2022

The features of modeling the training-competitive process of athletes and the reasons for the conflict of interest between its participants at various stages of training and competitive activity are highlighted. Modeling should be carried out taking into account certain regularities in the formation of a sports form, the effectiveness of participation in competitions, the individual characteristics of athletes, objective and subjective conditions in which the training process and competitive activity take place. The effectiveness of the preparation process lies in the correspondence of the content of practical modeling to the conditions and features of competitive activity. The main objective and subjective reasons for the emergence of a conflict of interest at various stages of training and competitive activity are identified through the prism of the main didactic principles of education. Conclusions: The organization and effective management of the process of training athletes provides for the development and implementation of various models. The initial data for modeling competitive activity are the results of athletes' performances in previous competitions, taking into account performance stability indicators, and not just the best result achieved in one competition. The features of the methodology for modeling the process of training athletes are in the individualization of the training process and the compilation of a predictive model for the implementation of their level of preparedness. Failure to respect the formal and informal relationship between the coach and the athlete leads to a conflict of interest. The grounds for contradictions and the emergence of conflicts can be both objective and subjective reasons, as well as mixed, objective- subjective reasons.
