Background and Aim of Study: The article deals with ICT concepts in the educational theory and practice of Ukraine. It is noted that scientists are exploring different aspects such as a concept, a strategy for implementing the concept, real experience, etc. The analysis of ICT concepts in education which were created during the independence period, has highlighted a number of contradictions that accompany this process. The aim of the study: to consider ICT concepts which were created in the system of education in Ukraine during the independence period. Material and Methods: In the study, the following general scientific methods were used: analysis (historical and pedagogical), synthesis, comparison, generalization. Results: ICT concepts implemented in Ukraine’s education, not only attest to the emergence of innovative information and technological realities in the field of science and education, but also are considered to be new realities, and therefore need to be researched by scholars of different branches – philosophers, educators, sociologists, psychologists, etc. – both in terms of methodology and trends of changes in the reference field of educational informatization. Conclusions: ICT concepts in Ukraine’s education, created during the independence period, reflect the course of a controversial process of a state formation. Being innovative by design, concepts, laws, strategies, programs, etc. have been based on traditional, or even outdated, principles of state development. A legislative approval of the National Program of Informatization and periodic changes in innovative nature of its content in relation to ICT in education, showed progressive trends of conceptual importance.

The global expansion of competent Dengue vectors in tropical and sub-tropical areas, and the favorable conditions for disease transmission demonstrates a critical public health challenge ahead. This review provides an insight into some key underlying gaps while attempting to suggest alternatives towards the containment and hence eradication of Dengue. The non-existence of an efficient vaccine against all DENV serotypes and the rapid global emergence of COVID-19, are undermining the complexities of vaccine development and disrupting global health efforts for the management of Dengue respectively. The development of sustainable DENV control programs now requires a multifaceted approach involving the integration of the recently developed multi-platforms application in entomological surveillance, community awareness, modelling, vaccination, vector control, and also ensuring that Dengue control efforts are not hampered or neglected during COVID-19 pandemic. This approach requires active collaboration and communication of scientists from various disciplines, economic support from funding agencies and institutions as well as support from the communities, governments and public health organizations.

This study was conducted to produce high-quality compost using both cow manure and wood ash that can specifically be used to increase the fertility of soils in tropical regions. Increased proportions of wood ash were co-composted with cow manure. During composting, the composts produced presented the classical composting temperature curve and attain a thermophilic composting phase (about 60 oC). After 117 days of composting, the produced composts (CMA 0%; CMA 5%; CMA 10% and CMA15%) had a C/N ratio between 16 and 30, and their pH, was basic, indicating maturity. They were rich in minerals (Mg; Ca; K+; and Na+) and poor in heavy metals (Zn; Cu and Pb). Wood ash addition raise the fungal communities except for CMA 0% and did not impair significantly on bacteria communities; however, addition of high amounts of wood ash could reduce the metabolism of the microbial communities including cellulase activity that showed a proportional decrease according to the added amount except for CMA 15%. The composts showed a germination index greater than 80% at all concentrations, indicating the absence of phytotoxicity. Therefore, co-composting of cow manure with wood ash (<15%) allowed to obtain a good organic fertilizer with higher liming potential, nutrient content, and less hazardous material which could be used in farms to remediate acidity of tropical soils

Background and Aim of Study: Migration is a complicated and complex social phenomenon. Arriving in a new country, immigrants find themselves in a strange, unfamiliar environment; simultaneously they may have left behind almost everything that they had in their home country. Such a life event changes the relationship between a person and their things: immigrants lose their connection with the things left behind, while new connections with the things of the host country have yet to be forged. This is a natural process of an adult’s migration. But what is it like for a child? The aim of the study: to reflect the experiences of immigrant children and their changing relationship with things in phenomenological methodology approach. Material and Methods: The article is based on hermeneutic phenomenology, when children migrating is analysed as a phenomenon. In order to investigate such phenomena phenomenology as a research strategy is applied. Its data were collected using several methods. The main method was the unstructured phenomenological interview with children and adults who due to economic reasons left their home country and came to live in another while being children together with their parents (or one of them). Having changed the country, they had also to change schools. Results: Show the uniqueness of the children migration experience and reflects it in the phenomenological matter. Conclusions: Children migration experience is often underestimated from the position of grown-ups, while children view migration differently, as they see things, objects and space around them differently (they see, feel and imagine world in a totally unique manner). That is why children taken out of their usual and normal lifestyle, home space facing totally different world, with strange and unfamiliar things, facing the world of unpredictability, temporality and eternity, fantasy and dreams, where misunderstood, or unnoticed are left alone, even while being surrounded by people.

Background and Aim of Study: The research work considers whether workplace stress had a negative association with university teacher’s family functioning, and if a social identification might a moderator role for this relationship. The aim of the study: to define the social identification’s role for work and family life balance. Material and Methods: The data were collected from participants (university teachers) with the scales (Perceived Stress Scale; Brief Family Relationship scale and The Three-Dimensional Strength of Group Identification scale) of multiple – choice questionnaire. Moderation analysis was conducted by using multiple linear regression analysis. Results: Author concludes that the impact of workplace stress on family functioning is dependent on individual’s social identification level with their family group. It is because the bivariate analysis results showed that workplace stress was a negatively affected to the family functioning (p<0.05). Moderation analysis indicated that the impact of workplace stress on family functioning is dependent on individual’s social identity level with their family members. The interaction between social identification and workplace stress was significant (p<0.05), that means social identification moderated the relationship between workplace stress and family functioning. Workplace stress would not negatively effect on family functioning (p>0.05) that individual’s whose social identification with their family was high. In contrast, lower identification with family had more significant negative impact from workplace stress on their family functioning. Conclusions: Social identification plays a significant effect for individual’s work and family life balance. Individual’s high social identification with their family is an effective coping method with workplace stress and, moderates the relationship between workplace stress and family functioning.

The major livestock feed next to natural pasture in central highlands of Ethiopia is cereal crop residue; however, supplementation with additional nutritional entities is most often recommended. The present study aims to examine the nutritive value of lentil haulm and how this value varies among the varieties and locations. For this, 80gms of haulm samples of Alemaya, Derash and local lentil varieties were collected with four replications from Bishoftu, Akaki, and Chefe-Donsa from on farm trial sites of Ethiopian institute of agricultural research. To test for the variation in haulm nutritional values among the varieties, two-way ANOVA was employed. The results showed that the interaction of variety and location had significant effect on crude protein (CP), neutral detergent fiber (NDF), metabolizable energy (ME) and in vitro organic matter digestibility (IVOMD) (P<0.05). Here, CP content of lentil haulm was higher for a local variety when compared with the two commercial varieties. The haulm yield (4.38t/ha) and haulm dry matter yield (3.97 t DM/ha) were higher for Derash when compared with that of the local variety (P<0.05). Overall, the present finding denoted that although in some cases the lentil haulm nutritional values and yields vary among varieties and were dependent on growing locations, it can be observed to have optimum feeding values to supplement livestock feed with the cereal crop residues in central Ethiopia.
埃塞俄比亚中部高地天然牧场旁的主要牲畜饲料是谷类作物残茬;然而，补充额外的营养实体是最常被推荐的。本研究旨在研究扁豆的营养价值，以及这种价值在品种和地点之间的变化。为此，从埃塞俄比亚农业研究所的农场试验点收集了80克Alemaya、Derash和当地扁豆品种的样品，并在Bishoftu、Akaki和Chefe-Donsa进行了4次重复。采用双因素方差分析检验各品种间牧草营养价值的差异。结果表明，品种和产地的交互作用对粗蛋白质(CP)、中性洗涤纤维(NDF)、代谢能(ME)和体外有机物消化率(IVOMD)有显著影响(P<0.05)。在这里，一个地方品种扁豆茎的CP含量高于两个商品品种。干物质产量(3.97 t DM/ha)和干物质产量(4.38t DM/ha)均高于地方品种(P<0.05)。总体而言，目前的研究结果表明，尽管在某些情况下，扁豆的营养价值和产量因品种而异，并取决于种植地点，但可以观察到，在埃塞俄比亚中部，用谷类作物残茬补充牲畜饲料具有最佳的饲养价值。

The third world countries are not just suffering from food shortage, they are also plagued by malnutrition which stems from poverty coupled with inadequate informations about the nutritional contents of foods consume by most of her populace. Yam is a stable food consume by millions of Nigerians and the decision of which species to consume is often based on palatability and availability. Proximate analysis was carried out on D. rotundata., D. cayenensis and D. alata to compare their protein, carbohydrate, moisture, crude fibre, fat and ash content. The result reveals that Carbohydrate content of D. cayenensis (50.60%) was higher when compared to D. rotundata (48.8%) and D. alata (36.02%). Also, the crude fibre of D. alata (5.26%) was significantly higher compared to D. cayenensis (4.86%) and D. rotundata (4.75%), similar result was obtained for the protein content of D. alata; which was 3.46% compared to D. cayanensis (2.13%) and D. rotundata (1.61%) respectively. This research concludes that the proximate composition of the Dioscorea species studied varied significantly. Yam consumers and nutritionist are advised to select their yam species in view of the various proximate constituents to achieve a well balance diet in terms of food and composite flour. The cultivation of the D. alata species should be encouraged because of its low Carbohydrate and high protein contents, thus making it suitable for diabetic patients or people suffering from related illnesses.

Yam consumers and nutritionist are advised to select their yam species in view of the various proximate constituents to achieve a well balance diet in terms of food and composite flour. The cultivation of the D. alata species should be encouraged because of its low Carbohydrate and high protein contents, thus making it suitable for diabetic patients or people suffering from related illnesses.","PeriodicalId":52800,"journal":{"name":"International Journal of Science Annals","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90458299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A comparison of the effects of solar radiation on sandy-loam and clay-loam soils with convective boundary condition was made. The dimensional governing equations (the continuity, momentum and energy equations) were converted to non-dimensional form using some set of dimensionless quantities, which resulted to a pair of partial differential equations of second order. With the use of perturbation method, these equations were reduced to ordinary differential equation and then solved analytically. Using the numerical values of the thermal conductivities of sandy-loam and clay-loam soils, a good comparison was made between the effects of the solar radiation parameter and internal heat generation parameter on the two soil samples. These results were worked out with the use of Matlab R2009b and visibly displayed on graphs for clearer illustration. For a rise in the intensity of solar radiation and mounting internal heat, the temperature of the soils increased generally. However, the proportion of moisture content influenced the level and the rate at which the temperature is boosted in both soil samples.
