Year: 2018

description: Due to innovative data services, the number of mobile subscriptions and amount of mobile data traffic will increase significantly globally. According to Ericsson mobility report, in 2022 the number of mobile data subscribers and traffic is forecasted to reach 9 billion and 71 Exabyte per month, respectively, from the current 7.5 billion and 8.8 Exabyte per month. Likewise, the report presented that Sub-Saharan Africa will also show a faster growth rate than any other region in the globe. 2018's Ericsson interim mobility report shows, Ethiopia is among five countries in the world that score high in mobile subscription growth. In addition, when we see historical records, market potential, and various telecom expansion plans of the country, mobile subscriber and traffic growth is expected in Ethiopia, particularly in Addis Ababa city. To accommodate the increasing mobile traffic, beside Long Term Evolution (LTE), several operators are deploying and optimizing LTE-Advanced and LTEAdvanced Pro mobile technologies. Having partially deployed LTE network in Addis Ababa, ethio telecom has not yet moved to LTE-Advanced but now considers to accommodate significantly increasing mobile subscribers, traffic and future demand of the city. To that end, there is a need of understanding techno-economically viable LTE-Advanced deployment scenarios for the local context. In this thesis, feasible LTE-Advanced deployment options are developed using scenario planning method. Following, TERA Techno-economic Analysis framework and methodologies are investigated and modified to evaluate possible LTE-Advanced deployment scenarios techno-economically assuming 6 years study period and 10% discount rate. In the framework market analysis and LTE-Advanced radio network dimensioning performed using COST-231 Hata model; existing LTE traffic, standard and demography analysis is conducted for macro and small cells, respectively. In addition, the required bandwidth for the study period is forecasted and determined. Based on resulted Net Present Value and Payback Period of techno-economic evaluation, an LTE-Advanced scenario that applies progressive deployment with out-of-band small cells is feasible for Addis Ababa but not the case for a scenario that applies full deployment with out-of-band small cells. In both scenarios it is shown that LTE-Advanced is feasible if deployed in dense urban and urban areas.

description: The exponential growth of demand for mobile broadband access in emerging cities has been pushing deployment of long-term evolution (LTE) mobile technology. However, technological advancement towards LTE alone cannot show the performance, acceptance, and economic viability of an investment without detail technical and economic feasibility assessment of possible LTE deployment alternatives. In this thesis, first potential LTE deployment scenarios analyzed and formulated through scenario planning method for emerging city. Then, techno-economic analysis consists of marketing forecast, radio access network dimensioning, cost and revenue modeling, and economic feasibility analysis for seven years study period assuming a monopoly telecom market using modified TERA model performed. For techno-economic evaluation, modified TERA model is implemented in the MATLAB. Results show that market potential and operating frequency have a great impact on network capacity, coverage and number of sites in the area which in turn influences the rate of return on investment. Deployment of LTE in 1800Mhz band under high and low demand capacity, and deployment of LTE in 2100Mhz band under high demand capacity are feasible with the payback period of less than 3.5 years for emerging city. From specially formulated deployments scenarios techno-economic results, coverage favored LTE deployment scenario (in 1800Mhz under low demand capacity) is technically and economically feasible for Adama city of Ethiopia in a monopoly telecom operator market with payback period of 3.25 years.

description: For mobile operators, delivering quality service to their customers is very important as service quality significantly affects their business. To achieve a consistent quality service delivery, they need to continuously monitor and analyze their network performance and timely address any obtained performance drops. Performance drops in mobile networks can be observed in key performance indicators (KPIs) of spatially distributed cells with different magnitude and at different time periods. As it is practically difficult to address all performance drops simultaneously, it is preferable to make prioritized corrective actions starting from cells with critical drops, also called anomaly cells. To detect anomaly cells, different automated methodologies have been proposed and analyzed. Yet, ethio telecom still applies manual and subjective anomaly detection method where measured KPI values are manually compared with fixed thresholds to determine if the measured values are within defined required ranges or not. Cells with KPI values out of the required range are analyzed for identifying performance drop root causes and taking corrective actions. The manual and subjective anomaly detection method is prone to detection errors and is maintenance time, manpower and then cost inefficient. These challenges of manual and subjective detection can be improved by applying advanced automatic methods based on machine learning algorithms. In this thesis work, KNN based anomaly detection algorithms such as KNN classification, local outlier factor (LOF) and connectivity outlier factor (COF) anomaly detection models is implemented, and their comparative evaluation are made for Addis Ababa LTE cells. The comparison is made based on type of output, complexity and their true positive rate (TPR) for time series and cell level detections. Unlike KNN classification, LOF and COF do not need heavy data set training and are able to provide anomaly scores instead of two-class labels. Experimentation results show that COF provides slightly better performance than the other models with negligible performance difference. For instance, the performance of COF with respect to TPR for RRC setup success rate in the experimentation is 97.91% for cell level detection and 88% for time series detection.

description: Australian media artists have a strong reputation as being amongst the most active, creative and innovative in the world. these artists and the infrastructures that support them have created a strong community of practice that has influenced both art making and art institutions here and internationally. Locating the exact time and place when this began is almost impossible. However, it is clear that since the early 1990s, the digital turn heralded by the emergence of the personal computer and the internet has led to an explosion of diversity in art practices. Tehse practices have not only created a breadth and depth of media art but along the way have tranformed many more traditional artistic forms from dance to painting to scultpture.

description: Information is becoming increasingly important factor in the era of globalization. Access to information is uneven due to rapid development of technologies, poor awareness, social and economic conditions and a range of other factors. Increasing information divide among people, over a period of time, is likely to bring about economic and social divides and hence a potential source of tension in society. The M.S.Swaminathan Research Foundation (MSSRF) based in Chennai had undertaken pioneering work in this area by addressing the need for bridging the information divide among rural and urban areas and among various sections of rural society through a network of Village Knowledge Centres (VKCs). Each VKC is located in a village and mostly consist of a few computers, electronic display boards and other information and communication equipment strategically housed to enable easy access to large sections of rural society. The model developed by MSSRF has been quite successful and the idea has impressed policy makers in India and several developing countries. The Common Service Centres (CSCs) promoted by the Government of India is a well known example of adoption of the template developed by MSSRF. Several institutions and corporate houses have also made use of these models for pursuing some of their strategic and commercial objectives.
Factors affecting the credit spreads behaviour of USD Malaysian bonds

Year: 2024

description: This paper addresses empirical analysis of Malaysian credit spreads in a number of directions. Firstly, the investigation of explanatory power of macroeconomic or market variables to the changes in the spreads. Secondly, use of daily data rather than data sampled to match typical macroeconomic data release. Third, a focused study on the market behaviour of bonds issued from a rapidly emerging market. Fourth, the inclusion of semi-parametric measures to better capture the behaviour of the credit spreads. This study finds that changes in credit spread of Malaysian bonds are only receptive to certain macroeconomic factors. Also changes in credit spreads are negatively correlated with the interest factor but this study could not find convincing evidence to support the argument of a negative relationship with the asset factor.

description: Introduction. One of main features deciding on functional abilities and agility of a man is his conative efficiency. The aim of the study was to determine the influence of physical effort on changes of skin temperature of each body areas and the analysis of dependence between the body temperature and the level of maximum absorption of oxygen (VO2max). Material and methods: The study group consisted of 7 women at about average age of 23.86 (±0.69) years. All participants of the study were healthy, did not have overweight nor chronic illnesses. They also did not do sport professionally. During the research each participant performed the effort in the form of 6 – 8-minute-long step Astrand – Rhyming test and then 10-12-minute-long run on the athletic track. Before and after the effort the women were examined by means of thermo visual cameras (temperature in front and back of the body). In the moment of effort ending studied persons had heart rate measured with heart rate monitor. Results. Statistically non-exchangeable temperature reduction of body surface on thighs, forearms, arms, trunk (both in front as well as the back) and behind shins was observed during the study. The greatest drop of about -1.13 °C, appeared behind shoulders, least, about -0.04 °C, on the back surface of the trunk. Only on front side of shins the temperature increased in non-exchangeable manner, about +0.06 °C. The important dependence (p<0.05) between the change of temperature in front (r=-0.82) and the back of the trunk (r=-0.78) as well as VO2max was shown. Conclusions: The higher pulse was measured at the studied participant the lower VO2max values were. There is dependence between the thermal reaction and the efficiency – the greater drop of temperature on the trunk the higher VO2max was. Thermal observation can be therefore helpful as indirect estimation of the efficiency in medicine and rehabilitation.
Innovation purity: Revisiting the exploration-exploitation debate

description: Trade-offs between the ”exploitation of old certainties” and ”the exploration of new possibilities” (March, 1991: 71) have long occupied a prominent place within the literature on learning and innovation (Levinthal & March, 1993; Nelson & Winter, 1982). Theoretical simulations, grounded investigations, and empirical analyses yield largely pessimistic forecasts. They suggest that exploitation often traps firms into suboptimal yet stable equilibria (Ahuja & Lampert, 2001; Levinthal & March, 1993), where firms not only get to know significantly less than they could but they also learn at a slower rate than relevant environmental changes may require (March, 1991), with self-destructive long-run consequences (Brenner & Tushman, 2002; Holmqvist, 2004). Alternatively, exploratory actions that increase variance in a firm’s knowledge sets, routines, and capabilities stimulate innovation and learning (Hargadon, 2002), often have significant short-term costs (Fisher & Ittner, 1999). The trade-off argument posits that, because exploration and exploitation exert countervailing forces on resources and strategies, firms are more successful when they focus on one or the other. Depending on the benefits sought, they periodically cycle between the two extremes (Holmqvist, 2004). Recent research, however, suggests that firms deliberately seek a balance between exploration and exploitation (Branzei, 2005; Gitleman & Kogut, 2003). However, maintaining an optimal mix is challenging-given ”[their] certainty, speed, proximity, and clarity of feedback” (March, 1991: 73), exploitation cycles are more tempting to initiate and harder to break, and thus often lure firms away from exploration. Opposite arguments co-exist in the literature. On one hand, a long tradition in learning curve advantage (Darr, Argote & Epple, 1995) and competitive advantage (Barney, 1991; Porter, 1985) suggests that focusing on one at the expense of the other yields superior payoffs. The attention-based view of the firm corroborates this prediction, suggesting that pure exploration or exploitation better mobilize resources and talent and thus is more likely to attain the desired results. Alternatively, March and his adherents have consistently argued for the benefits of ’balancing’ the two, suggesting that an optimal mix helps firms attain both short-term cost advantages and long-term positioning advantages.

description: Purpose: This study aimed to evaluate the effectiveness of a school-based intervention designed to enhance social and adaptive skills among children with Attention Deficit Hyperactivity Disorder (ADHD).

Methods and Materials: A randomized controlled trial (RCT) was conducted with 30 children diagnosed with ADHD, aged between 8 and 12 years. Participants were randomly assigned to either the intervention group (n=15) or the control group (n=15). The intervention group participated in a ten-session program over ten weeks, focusing on social and adaptive skills training. The control group received standard care. Data were collected at three time points: pre-intervention, post-intervention, and five-month follow-up, using the Social Skills Rating System (SSRS) and the Adaptive Behavior Assessment System, Second Edition (ABAS-II). Data were analyzed using repeated measures ANOVA and Bonferroni post-hoc tests in SPSS-27.

Findings: The intervention group showed significant improvements in social skills from pre-intervention (M = 45.67, SD = 3.45) to post-intervention (M = 50.35, SD = 3.12) and follow-up (M = 48.76, SD = 3.30). Similarly, adaptive skills improved from pre-intervention (M = 42.53, SD = 3.21) to post-intervention (M = 47.28, SD = 2.98) and follow-up (M = 45.89, SD = 3.09). Repeated measures ANOVA indicated significant main effects of time on social skills, F(2, 56) = 35.78, p < .001, and adaptive skills, F(2, 56) = 32.45, p < .001, as well as significant interaction effects between time and group for both social skills, F(2, 56) = 20.12, p < .001, and adaptive skills, F(2, 56) = 16.93, p < .001. Bonferroni post-hoc tests confirmed significant differences between pre-intervention and post-intervention, and pre-intervention and follow-up for the intervention group (p < .001).

Conclusion: These findings underscore the importance of incorporating structured, skill-building programs into school curricula to support children with ADHD.

description: Aim: The aim of the study was to determine differences in the level of motor abilities of 7-9-year-old girls and boys in relation to the socioeconomic status of their families. Material and Methods: The research was conducted in 12 primary schools in two regions of Poland namely of Warmia & Mazury and Pomorskie voivodeship, on the total of 1205 pupils (584 boys and 621 girls) aged 7-9. Selected economic factors such as the type of school (public or private), monthly income per household member, and the number of children in a given family were accepted as the independent variables. The factors behind social status included the place of residence and parents’ educational background. In order to determine the level of motor abilities, 13 motor tests were applied. Results: The research revealed that motor tests such as 1 and 3 min. Burpee test and medicine ball throws (forward and backward) appeared to show the biggest differences in the level of motor abilities of the children whose social and economic status varied. The results of these tests as well as those of the shuttle run were significantly higher for the girls from the families of high social status than for the boys of low social status. Social status to a greater extent than economic one differentiated the tested motor abilities, especially in the case of the girls from families marked by high social status, who scored better than boys. The exception is the skipping with clapping of hands – 8 s trial, which differentiated only the tested categories of economic status, especially when referred to the girls. Conclusions: Owing to the small number of significant differences between high and low social and economic status in both sex groups in the motor tests applied, it can be assumed that in the less developed, agriculture and tourism-oriented areas there has occurred blurring of the differences in the level of children’s motor abilities depending on their social and economic status.

description: Purpose: to analyze the biomedical and social determinants of health and hygiene of pupils athletes. Material: the study involved 60 athletes 12-15 years and their peers (n = 60), which are not involved in sports, as well as parents of schoolchildren. Comprehensive study was conducted using questionnaires by the "copy - a couple." Results: it was found that young athletes have less influence adverse biological factors than their peers. Systematic sports distract students from passive pastime and regulate rational mode of the day. Food of young athletes has the following features: Custom mode, high multiplicity meal predominance in the diet of vegetables, meat and dairy products. Found that most of the families of pupils athletes have sufficient material level and adequate housing. At the same time, parents of the ordinary students are more prone to the spread of harmful habits. Psychological climate in families of pupils is low conflict. Medical support is stable, but not sufficient. More than half of the families of pupils - athletes perform medical advice given extra hygiene knowledge. Conclusions: the students who participate in sports is a specific social-demographic group. The main factor of social and pedagogical state of the family is the attitude of the parents to the child's health.

Year: 2019

description: In cellular mobile networks due to the emerge of different application services, the data traffic generated by these application services is increasing. Moreover, the traffic consumption pattern is changing in time and space. Understanding and characterizing the traffic demands and dynamics associated with different mobile services (e.g., knowing when and where users use dominant application services) is instrumental for operators. By doing so, operators can improve application services usability, optimizing network service quality and use it as an input for technical and business strategies. In the case of ethio telecom, the sole telecom service provider in Ethiopia, knowledge of the application services distribution is not a known practice. Therefore, the main purpose of this thesis work is modeling the spatial and temporal traffic distribution of observed application services for Addis Ababa Universal Mobile Telecommunication System (UMTS) network. In this regard, to study a temporal and spatial distribution analysis of the traffic density (the traffic load per unit area) for selected mobile application services, data traffic is collected from 739 bases Stations (BSs). To model the temporal distribution of the selected application services, which are Streaming, Social Networks and Web browsing, four candidate models: Normal, Lognormal, Weibull and Stable are used. Based on maximum log-likelihood and probability plot evaluation criteria, out of four models, a Stable distribution modeling best fit for this particular application services. Similarly, to model spatial distribution, out of the candidate four models, Weibull distribution model best fits for these particular services.
Managing Cross-Border Cellular Networks Interference via Game Theorybased Spectrum Sharing

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The need for wireless services and high data rate is growing rapidly as a result of development of communication technologies. The challenges for operators to meet this rising demand of high data rates is radio spectrum which is a scarce and expensive resources. This scarcity arises from the exclusive allocation of the available spectrum relatively from the physical scarcity and has inefficiency in bandwidth usage. To improve capacity and Quality of Service (QoS), it is essential to pay closer attention in increasing operational bandwidth. The viable option to increase this operational bandwidth is spectrum sharing between operators. It refers to the common uses of a specific range of spectrum simultaneously by operators operating in the same geographical area. However, the main problem in operating with same frequency bands without coordination causes inter-operator or Cross-Border Interference (CBI). The mitigation techniques currently working for managing this type of interference is the physical and logical parameter optimization which is not effective. In this thesis, an efficient approach of dynamic spectrum sharing among operators is proposed to alleviate this problem. The basic idea is to partition the available spectrum into private and shared frequency bands by exchanging spectrum usage favors from the common pool to minimize interference. We address this issue for two operators' spectrum sharing operating in the same geographical area. Most of the mathematical models considered all over this thesis are based on the Game theory to model and analyze their competitive interactions. A strategic non-cooperative game is modeled to maximize throughput, where the operators simultaneously share the available spectrum dynamically as per their relative requirement. Finally, based on the simulations, the expected results of the proposed schemes outperforms the existing Fixed Spectrum Access (FSA) schemes under varying load factors.

Agent-based QoS management for web service compositions
Creators: name: Nguyen, Xuan Thang
Publisher: name: Swinburne
Year: 2024

description: Service oriented computing (SOC) is fast becoming the core platform for software applications and integrations. In SOC, applications are modeled as collections of loosely-coupled, interacting services that communicate using standardised interfaces and protocols. These services can be combined together to form new value-added services, or compositions which potentially span across many administrative boundaries. Managing the quality of Web service compositions is important. However, it is difficult in practice. The difficulty lies in the complexity of composition dependencies such as sharing computing resources or component services. The distributed nature ofWeb services presents another challenge where a service composition may involve service providers from different organizations and administrative domains. A viable collaboration between these service providers is necessary for any successful management. This thesis studies the Quality of Service (QoS) management for multiple service compositions. Despite many approaches having been proposed for the management recently, those approaches are limited to an individual composition and management functionalities executed by a single organization. This thesis aims at providing solutions for those limitations. It has the following contributions: - A new framework supporting a distributed approach to solve the QoS management problem for multiple inter-related compositions is proposed. This problem has not been well investigated in the current Web service research. In the thesis, fresh ideas from Distributed Constraint Satisfaction (DisCSP) research are employed and applied practically to the Web service environments. - Extensions and improvements to existing DisCSP algorithms are suggested. This enables existing DisCSP algorithms to be used practically in the framework. In the adaptations and improvements, existing DisCSP algorithms are reviewed. Their possible limitations when being used in the Web service environments are analysed and addressed adequately. - New DisCSP algorithms to solve the QoS management problem are proposed. These newly proposed algorithms can model different preference levels of service providers and work in dynamic environments where compositions and constraints on QoS variables can be added or removed. Optimization of preferences of service providers can also be achieved by using some of the algorithms. - A novel verification mechanism, for checking the conformance of service providers to a DisCSP algorithm, is developed, and thus allowing the algorithm to be used practically in an untrusted environment such as that of the Web services.

description: Purpose: This study aimed to compare executive functions and working memory among children with high and low levels of physical activity, providing insights into how physical activity influences cognitive development in school-aged children.

Methodology: A cross-sectional design was employed, involving 269 children (128 girls) aged 9 to 12 years from regular schools in Tehran. Participants were selected using convenience sampling. Executive functions were assessed using the Behavior Rating Inventory of Executive Function (BRIEF), working memory using the Wechsler Intelligence Scale for Children - Fifth Edition (WISC-V), and physical activity levels using the Physical Activity Questionnaire for Children (PAQ-C). Data were analyzed using SPSS version 27, with descriptive statistics calculated and independent samples t-tests conducted to compare cognitive functions between high and low physical activity groups.

Findings: The results indicated significant differences between the two groups. Children with high levels of physical activity demonstrated better executive functions (M = 53.67, SD = 7.89) compared to those with low levels (M = 56.79, SD = 8.22), with a t-value of -3.12 (p = .002). Similarly, working memory scores were higher for children with high levels of physical activity (M = 110.24, SD = 14.78) than for those with low levels (M = 104.72, SD = 15.61), with a t-value of 3.58 (p = .0004). These findings suggest that physical activity is positively associated with better cognitive functions in children.

Conclusion: The study provides evidence that higher levels of physical activity are associated with improved executive functions and working memory in children. These findings emphasize the importance of promoting physical activity in schools and communities to enhance cognitive development. Further research using longitudinal designs and objective measures of physical activity is recommended to explore causal relationships and broader implications.

description: The need for timely delivery of real time and mission-critical applications has led to a high demand for end-to-end QoS guarantees. Service providers, including Ethio telecom, have deployed mobile backhaul in addition to IP core network with separate MPLS domains for each network. Internal network topology of one domain and its policy implementations are proprietary information and inter-domain routing must be done without detailed knowledge of the entire network topology, policies and performance of the other domains. Lacks of global coordination between policies used in different domains, limitations of BGP for implementing end-toend QoS in inter-domain routing and its slow convergence during network failure are major challenges of the current inter-domain routing architecture. As stated by different authors such as in RFC 8277 (Using BGP to Bind MPLS Labels to Address Prefixes), Seamless MPLS provides framework for taking MPLS end-to-end in a scalable fashion, extending benefits of traffic engineering (TE) and guaranteed service-level agreements (SLAs) with deterministic network resiliency. It offers an alternative for implementing end-toend MPLS networks by integrating different domains into a single MPLS domain. The motivation of this thesis is to investigate and analyze impacts of implementing Seamless MPLS on QoS parameters. The impact on QoS parameters is analyzed by using two scenarios; MPLS with multiple domains and Seamless MPLS integrating three domains in to single MPLS domain. Simulation tools such as eNSP, Ostinato, NQA and MATLAB are used to compare performances of the two scenarios. The analysis results show that in Seamless MPLS throughput is improved by 36.87%, latency is improved by 15.98%, packet loss is improved by 20% and jitter is improved by 12.5% compared to MPLS. From the results one can understand that any service provider can benefit from deploying Seamless MPLS.

description: All systems do not require security at the same level. Sensitive information such as financial transactions require higher level of security in terms of confidentiality, integrity and availability. Mobile Financial Service (MFS) is making financial transaction using mobile devices. Due to the inherent nature of MFS using wireless technology, it makes the service susceptible to different attacks. Currently, in Ethiopia mobile financial service is mostly being provided using Unstructured Supplementary Service Data (USSD) technology. This study first identified many vulnerabilities and possible attacks that can be made on the current scheme by reviewing existing literatures. On top of this, analysis of existing MFS technologies has been made. Accordingly, Subscriber Identification Module (SIM) based approach is suggested since it is more applicable for the case of Ethiopia. The newly designed framework is found to be better than the original model in terms of security (confidentiality and integrity). The study further investigated usability of the existing and newly proposed models' user interface with a sample of 37 experts from ethio telecom and Commercial Bank of Ethiopia. Results from the experiment indicate that the current scheme took statistically significant time to complete a given task than the proposed model. The current model is preferred by participants on some of usability parameters such as learnability, satisfaction and ease of use. Overall, 94.6% of the experts involved on the experiment preferred the proposed model due to its security (better authentication using One Time PIN (OTP) code).

description: Adaptive Random Testing (ART) is an approach to testing software based on Random Testing (RT), but incorporating additional mechanisms to ensure a more widespread and even distribution of test cases over the input domain. It has been found that ART, under certain conditions, can significantly outperform RT, in terms of number of test cases required to detect a failure (a measure referred to as the F-measure). One implementation of ART. based on the use of exclusion zones and restriction of test case selection to outside of these zones, is Restricted Random Testing (RRT). In this paper, we present an overview of the basic RRT method. using circular and spherical exclusion regions, and then introduce an alternative exclusion shape, motivated by the promise of lower computational costs. Investigation into this alternative shape (square) exclusion method lead to a hybrid implementation of RRT, called filtering. Filtering enables the combination of the computationally cheaper square exclusion shape and the faster (for failure finding) original, circular exclusion shape. Simulation and experimental evidence are also presented supporting the methods.

description: The food system has significant potential to influence the wellbeing of individuals and the planet. Addressing challenges within the food system requires integrated solutions that take into account the complex interconnections with other systems and multiple stakeholders. In our increasingly urbanized world, cities are key players in fostering just and sustainable transformations. Due to their close relationships with residents, businesses, and community organizations, they are in a position to develop integrated policies that address different concerns at different levels, both horizontally (i.e. sectoral and territorial) and vertically (i.e. multi-level).

This report aims to offer a deeper insight into the topic of integrated urban food policies (UFPs) with the objective of informing and inspiring pilot actions and experimentation.

Following an initial exploration of fundamental concepts tied to food policy integration from around the world, this report analyses thirty notable selected examples of urban food policies currently in practice.

Finally, the report provides recommendations that are tailored for both municipalities and Living Lab teams. These recommendations serve as practical guidelines, outlining strategies to ensure comprehensive approaches for the integration of urban food policies into existing frameworks, thus facilitating a tangible shift towards the establishment of sustainable and integrated urban food systems.

description: Purpose: Analyzed features of motivation to achievement and need to praise the students of secondary and high school. Material: In the survey took part 1634 students of secondary school in Kharkov, Vinnitsa and Lugansk regions. Carried out a comprehensive psychological testing, which allowed to find out the level of motivation of students to achievement and need for praise. Results: It is shown that during the period of study at school from fifth to eleventh classes a number of students have a low motivation to achievements, and low need for praise. Confirmed provision indicates that the modern school is still not fully realized the potential of educational pedagogy. Conclusions: It is shown that the formation personality physical education students in general education is possible only with the active and conscious of their participation in various forms of sports and recreation activities undertaken in the modern school.

description: Après l’accouchement, la jeune maman, âgée de 20 ans, a donné à son bébé son premier lait (le colostrum) dont elle décrit l’aspect, la couleur et déclare avoir pris connaissances de ses propriétés et qualités. Son lait étant insuffisant elle a recours au lait du commerce. Pour que celui-ci soit plus abondant et pour faire monter le lait, elle dit consommer beaucoup de soupe. Elle décrit sa préparation à l’allaitement (massage des seins) et imagine le circuit qu’elle pense que le colostrum parcourt, à partir du quatrième mois de grossesse, pour arriver aux seins. L'enquêtrice demande si elle pense que le colostrum a une influence sur les liquides corporels du nourrisson comme celle de permettre d’évacuer des matières. A la question sur les différences entre les filles et les garçons la mère déclare que la seule chose qui diffère c’est la quantité de lait avalée qui est plus importante pour les garçons.

Visuality and tacit knowledge: the application of multiple intelligences theory to the design of user expeience in interactive multimedia contexts

description: The major challenge for multimedia designers is to create user experiences that enrich the reception of content, designer's traditional reliance on intuition not ensuring audience's interest or understanding. The developing philosophy of user-centred design argues that designers should begin from an appreciation of their audience. In design there are various positions on how to achieve this, ranging from traditional market research through psychological, ethnographic, anthropological and sociological research to the direct involvement of users in the design process. This study draws on established knowledge about the cognitive processes, psychological motivations and preferences of user groups to advance a model for better-targeted and more effective design. In particular, it uses Howard Gardener's multiple intelligences theory to extend design thinking. Where a specific audience is apparent multiple intelligences theory implies that (1) the interface should match user's perceptual tools, cognitive styles and responses and (2) there is far greater scope than presently recognized to vary the design of the graphical user interface. The research explores how interactive multimedia can harness the 'language of vision' (Johannes Itten) for certain audiences, in this case Taiwanese drawing students aiming to enter tertiary art and design programs where high academic drawing skills are an important selection criterion. The high 'visual intelligence' of the target audience indicates their heightened capacity to process visual concepts and elements. The application of Gardner's ideas is a speculative one, based on hypothesis and the formulation of an experimental graphical user interface environment built around predominantly visual cues. The designed outcome incorporates knowledge and understanding that is widely applicable to GUI design, challenging designers to develop multimedia products with innovative, imaginative design approaches that cater for the different needs and interests of users where the audience is a specific and identifiable one.
