The significance of traditional costumes and designs as cultural symbols at Asorgli festival in Ho, Volta region

Costume and design within indigenous societies are transmitted from one generation to another and are established through periods of relatively long usage establishing what is known as clothing customs. Costume and designs at Asorgli State during festivals has become too adulterated and lost its finesse. The costume that patrons of the Asorgli festival wear for the occasion has dramatically deviated from what it is supposed to be and this trend has made Asorgli festival lose its credibility and cultural significance. Based on this the study aimed at the significance of traditional costume and designs as cultural symbols at Asorgli festival in Ho, Volta Region. The objectives of the study were to explore the traditional costumes and designs at festivals in the Asorgli traditional area, identify the factors that affect traditional significance of Asorgli traditional festival and strategies to enhance the significance of the traditional costume and designs. The researcher adopted survey as the research design for the study. Purposive sampling and simple random sampling technique were used to collect data. The study used questionnaire, interview and observation as the instruments for data collection. The study found that African prints, "Kente" and "Adawu" are the main costumes and designs used by the Asorgli people during festival. The study indicated that the arrival of western education, contacts with other cultures, and creativity and innovation affects the traditional significance of Asorgli traditional festival. Based on this, conclusion was made and it was recommended that the traditional leaders should enforce the young people to promote their cultural significance through costumes and designs during the festival. The community leaders especially the Asorgli (Asorgli traditional ruler) should ensure that the festival is celebrated in a peaceful displayed of their costume and designs in a conducive atmosphere.

A simple design method for nonlinear control of powerfactor correction boost converter

Typical switched-mode power supplies employ diode rectifiers for the AC to DC conversion. They draw input current in short pulses rather than in smooth sine waves and this puts stress on the wiring, circuit breakers and even distribution equipment provided by utilities. This type of utility interface generates harmonics and both of the input power factor (PF) and total harmonic distortion (THD) are poor. To minimize the stresses and maximize the power handling capabilities, active power factor correction (PFC) circuitry can be added to improve the shape of the input current. This work is aimed at providing a simple design method for power factor correction (PFC) boost converter for a non-linear power system to improve the disturbance rejection and speed of response of the conventional nonlinear cascade controller. Model based cascade controller design is presented for the control of PFC boost converters. Also, a dead band relay is introduced in the voltage loop to improve the disturbance rejection and speed of response of the PFC boost converter. Circuit implementation of the proposed control scheme is presented and simulation results are included to demonstrate the effectiveness of the proposed design scheme. The outcome indicated that resultant power factor is over 0.99, the total harmonic distortion of supply current is less than 2.9% and the efficiency of the converter is 93% at full load. It is recommended that a MOSFET based switching device could be used to improve the system.

Simulation of bioconvection in the suspension of second grade nanofluid containing nanoparticles and gyrotactic microorganisms

A time dependent symmetric flow with heat transmission of a second-grade fluid containing nanoparticles and gyrotactic microorganisms between two parallel plates in two dimensions is explored. Partial differential equations furnish the nonlinear ordinary differential equations due to the usage of relevant similarity transformations. Motion declines due to second grade fluid, energy elevates due to thermophoresis, concentration enhances due to Brownian motion and gyrotactic microorganisms profile elevates due to Peclet number. The unsteadiness parameter ? has profound effect on the nanobioconvection flow within the plates. Optimal homotopy asymptotic method (OHAM) is followed to evaluate the transformed systems. Consistency and smoothness between the first and second orders of the optimal homotopy asymptotic method are revealed through graphs. Also, graphs are provided to manifest the impacts of each parameter. � 2018 Author(s).

Single parenting and academic performances of students in Senior High Schools in the Mfantsiman Municipality

The future success of children depends on the household they grow up in, and parents are the first point of contact for children. Evidently, when one parent is absent, a gap is created as the child loses the support that would have emanated from both parents. Education is a great equalizer in Ghanaian society and is seen as a tool for national development. The role of parents is to support and enrich the educational processes, safety and health of their children. The interest of this study is to examine single parenting and the academic performances of senior high schools students from single parents family in the Mfantsiman Municipality of the Central Region of Ghana. Specifically, the study investigated levels of single parental involvement in students’ academic work, the influence the gender of students from single parents family have on their academic performances and ultimately, the effect of single parenting on students’ academic performances in the Municipality. A quantitative research approach and a social survey design were employed in the study, sampling 200 students from single parents’ family from four selected senior high schools in the Municipality using a purposive sampling technique. The researcher used a questionnaire and students’ academic record for the primary sources of data for the study. Results show that single parents of sampled students were mostly involved in the academic work of their wards, though mostly at the school rather than in the home environment. Secondly, single parents were generally more involved with the Girl than the Boy in relation to their academic work. Finally, results revealed that there is no statistically significant relationship between single parenting and students’ academic performances. These results signify that the absence of a parent does not necessarily have influence on students’ academic performances. Therefore, it is recommended that single parents should be more involved in their male wards academic work both at home and at school.

Single-frequency ultrasonic extraction of bioactive chlorogenic acid from heilong48 soybean variety: Parametric optimization and comprehensive evaluation of physicochemical and bioactive properties

Chlorogenic acid (CA), especially that found in soybean, is a rich bioactive compound but has received very little attention in research settings in past decades. Ultrasonic-assisted extraction (UAE) could be an efficient method to increase CA release from soybean. Hence, this study aimed to optimize UAE parameters for CA extraction from heilong48 soybean (HS) variety with comprehensive physicochemical and bioactive properties evaluation. Optimization of ultrasound parameters with Box-Behnken design (BBD) found frequency (20.0�kHz), power density (30.0�W/L), temperature (37.9?), and time (28.0�min) as the significant optimized parameters, which gave CA yield of 5.007���0.033�mg/g and DPPH of 93.197���0.213�?mol AA eq/g dry sample and were higher than that of nonultrasound-treated (raw) HS sample (CA yield, 1.627���0.528�mg/g, and DPPH, 10.760���0.207�?mol AA eq/g dry sample). A satisfactory model was obtained. SEM results confirmed the structural alterations of HS variety caused by the optimized UAE parameters. High TPC (4.726���0.002�mg GAE/g), TPA (1.883���0.005�mg GAE/g), and low TFC (0.040���0.008�mg RE/g) were obtained. A positive linear correlation between antioxidant activity and TPC was established. Protein�phenolic interaction in HS variety was observed. The results proposed that polyphenols should be considered as a significant component of HS variety. Likewise, HS variety could be utilized for CA extraction. � 2021 The Authors. Food Science & Nutrition published by Wiley Periodicals LLC.

Slip flow of Eyring-Powell nanoliquid film containing graphene nanoparticles

The purpose of the present study is to discuss the effects of graphene nanoparticles on two dimensional magnetohydrodynamic unsteady flow and heat transfer in a thin film Eyring Powell nanofluid past a stretching sheet using velocity slip condition. The contents of graphene nanoparticles increase simultaneously the thermal conductivity and stability when incorporated into the dispersion of water based liquid network. The basic governing equations for velocity and temperature of the Eyring Powell nanofluid film with the boundary conditions easily and simply provide the transformed nonlinear coupled differential equations by employing appropriate similarity transformations. The modeled equations have been evaluated by using an efficient approach through homotopy analysis method which lead to detailed expressions for the velocity profile and temperature distribution. The present work discusses the salient features of all the indispensable parameters of velocity and temperature profiles which have been displayed graphically and illustrated. Skin friction and Nusselt number show an excellent agreement with the published work. The results are useful in the analysis, design of coating and cooling/heating processes. � 2018 Author(s).

Smart energy saving system using a pir sensor in a classroom

Energy saving methods vary and includes human action (manual operation) and automation (programming). Depending upon the type, mode of operation can significantly provide a unique way of saving energy. This research presented a proposed smart energy saving system using a PIR sensor in a classroom; this uses infrared (IR) remote control system to switch „on‟ or „off‟ an energy system in the absence of human beings. Satisfactory results of signal transfer from the remote control to the fan and light was achieved. The circuit consists of PIR and Temperature sensors, and a microcontroller-based automation along with a temperature and motion display using LCD to switch „on‟ and „off‟ fan and light circuits. An embedded system was employed in constructing the energy saving system. Four different softwares were used for the testing to authenticate the performance of the work. They are Windows operating system (windows 7), Cadsoft EGLE software, Multism software and Hyper terminal (arduino 1.6.3). The testing was done with an intelligence signal at different stages. The test results indicated a successful implementation of the work compared. The device is made up of two sensors, and a time delay of 10mins. More than two sensors can be used to achieve more clearance and a time delay of 60 seconds. The findings of this research will be very meaningful to many stakeholders.

Social and academic experiences of students who are deaf at the University of Education, Winneba

This phenomenological study explored the social and academic experiences of students who are deaf at the University of Education, Winneba (UEW). Fourteen deaf students who are deaf were purposively sampled from a population of 36 students. Data were gathered through a semi-structured interview guide. Data were coded and analysed using thematic approach. Results of the study indicated that students who are deaf had varied social experiences. Whereas some preferred being at the same place with their hearing colleagues, others saw that as a waste of time. Academically, participants indicated that they were usually assessed on content areas they were taught. They added that assessment became difficult when Sign Language interpreters were absent. The study recommended that the university employ more Sign Language interpreters, and note-takers to help deaf students improve the social, and academic experiences.

Social inclusion experiences of deaf students at the University of Education, Winneba.

This interpretive study examines the social inclusion experiences of deaf students at the University of Education, Winneba, Ghana, utilising a phenomenological case study design. Employing maximal variation sampling, the research comprised thirtytwo deaf students from seven departments. Data were collected in two phases through focus group discussions and observations via video. Thematic analysis, guided by Braun and Clarke's (2019) reflexive approach, revealed the views of deaf students regarding their social inclusion beyond academic activities. Findings indicate that social inclusion is a multidimensional concept encompassing physical, emotional, and behavioural adaptations necessary for fostering an inclusive environment that promotes belonging, respect, and dignity. Deaf students exhibited a preference for interactions with hearing peers, although their participation in social activities was often minimal due to personal attributes such as shyness, as well as environmental barriers including communication challenges and discrimination. Moreover, while deaf students employed various multimodal strategies such as sign language interpreting, writing, gestures, and technology to facilitate interactions, they reported limited institutional support for social inclusion. The study highlights the urgent need for enhanced support mechanisms, including the establishment of a deaf-hearing buddy system and proactive policies promoting understanding of deaf culture. Recommendations aim to improve social inclusion through educational initiatives, active participation in university activities, and the provision of comprehensive support services. These measures are essential for enriching the social experiences of deaf students within the university community.

Social inclusion of pupils with intellectual disabilities at Adukrom Methodist Basic School in the Eastern Region of Ghana

The purpose of the study was to explore the level of social inclusion of pupils with intellectual disabilities at Adukrom Methodist Basic School in the Eastern Region of Ghana. Qualitative method and case study were used to guide the study. The sample size for the study was 21 students with intellectual disabilities, and data were collected using interview and observation. The purposeful sampling technique was used to select the sample size. Data were analyzed using themes and data from the respondents. The results of the study showed that pupils with intellectual disabilities were averagely involved in social activities. The major approaches teachers used to promote social interactions among pupils with and without intellectual disabilities were sports and games, and music and dance. The major factors that affected effective social inclusion were inadequate sports facilities, inadequate special needs teachers, perception and attitudes of some teachers in the school. It was recommended that teachers with special educational needs background should organize sensitization programmes for other teachers in the school. In addition, the school administration and opinion leaders connected with the school must appeal to the Ghana Education Service and other non-governmental organizations for appropriate sports facilities, and suitable teaching and learning resources.

Social inclusion of pupils with visual impairment at Bechem demonstration basic school, Brong Ahafo

The case study research design was used to guide the study. The sample size for the study was 21. Purposeful and random sampling techniques were used to select the sample for the study. Observations and interviews were used to collect data for the study. The data were analyzed using frequency counts involving simple percentages presented on Microsoft excel worksheet and content analysis technique using themes and data from respondents. The results revealed that pupils with visual impairment showed rare social interaction relationships with peers without visual impairment both inside and outside of the classroom. Pupils with visual impairment were less preferred in mixed activities interactions with group peers without blindness. Pupils without visual impairment avoided participation in activities that were likely to result in social interaction and facilitate friendship that take place frequently with the pupils with visual impairment and as a result made them experienced greater levels of loneliness, isolation and inter-personal conflict. Pupils without blindness also demonstrated similar rare social inter-personal conflict with their peers with blindness. It was recommended that pupils with visually impaired, teachers, parents and other providers of care, need information on how to interpret behavioural cues and recognize the children's attempts to interact. Finally, it was recommended that social skills intervention should be implemented by teachers.

The Social Intentionality of Battered Women�s Agency in Ghana

There is a growing body of research which suggests that victims of intimate partner violence (IPV; mostly women) continue to remain in abusive relationships. Many of the Western psychological theorisations focus on battered women�s personal dispositions and/or the self-creating (individualistic) view of agency to explain why victims remain in violent relationships. These studies seem to suggest that staying in a violent relationship is a personal decision that victims make in free will, and that victims who continue to stay fail to act on their own behalf. Drawing upon the Ghanaian communal conceptualisation of personhood and the social norms of marriage and divorce, this study questions the individualistic theorisations of battered women�s decisions to stay in or leave abusive relationships. The article argues that battered women�s agency in negotiating the stay/leave decisions in abusive relationships does not only originate in an independent autonomous self, nor constituted by a person�s internal motives, but also, and even primarily, it is culturally grounded and dependent on social relations for its realisation. The article concludes that the agency of abused women in Ghana has a social intentionality, in the sense that battered women�s intentional behaviour in marital relationships is both constituted by self and constrained by their relational embeddedness. � 2018, � 2018 Department of Psychology, University of Allahabad.

Social interaction between pupils with hearing impairment and their hearing peers in the University Practice Inclusive school, Winneba

The purpose of the study was to find out the social interaction pattern between pupils with hearing impairment and their hearing peers in the University Practice Inclusive School, Winneba. The study was qualitative which utilized a phenomenological design with interview and observation as the data collection procedures. A sample of 8 pupils comprising 5 pupils with hearing impairment and 3 with normal hearing were purposefully sampled. Data from the study was thematically analyzed based on the emerging themes. Findings from the study revealed among other things that the pupils with hearing impairment had interaction with their hearing peers both inside and outside the classroom. Additionally, there was a symbiotic relationship between the pupils with hearing impairment and their hearing peers. However, the hearing impaired pupils were battling with how to sustain interaction with their hearing peers as a result of their communication difficulties. The study recommended that regular counselling should be given to each group of Pupils in the UNIPRA Inclusive School to enhance the level of friendship between pupils with hearing impairment and their hearing peers. Also, regular interaction should be encouraged between pupils with hearing impairment and their peers at the UNIPRA Inclusive School in order for the pupils with hearing impairment to continue enjoying the benefits such as getting vital information from friends initiating and sustaining interaction and turn taking.
