Since the turn of the century there has been the advent of many wearable health monitoring devices. This new trend gained traction as health Service Provider (SP) want to know the health status of their clients in real time. Another reason for this is the fascination of peo-ple to monitor their health and daily physical activities. The Personal Health Information (PHI) measured by these devices send infor-mation by Bluetooth to Smartphones for onward delivery to the SP. However, it has been observed that there are some security issues (privacy of personal health information, location, etc.) associated with such procedure. Hence, discouraging some persons from using it. In lieu of this, this paper proposes privacy-preserving techniques in mobile health without the use of Smartphones. The absence of Smartphones in this protocol brings to the fore added security and hence privacy of PHI is assured. There is also the authentication of the clientsβ biometrics before the PHI is sent to the SP. This is to ensure that the PHI sent to the SP is from the right client.

Corporate governance has become an issue of global significance and has received new urgency due to various corporate scandals and failure. This study investigates the effect of corporate governance characteristics on Ethiopian sample private commercial banks financial performance as measured by return on asset and return on equity using eight years data from the year 2008 to 2015 with a sample of seven Ethiopian private commercial banks. To achieve the objective, the study employed mixed type research approach. Study used most of secondary data collection. In depth interview also conducted in structured form to get subjective responses regarding to corporate governance related factors influence on financial performance. The data was analyzed using multiple panel linear regression and the result is presented in descriptive, correlation, and regression analysis. Two financial performance indicators such as return on asset, and return on equity were used. Corporate governance characteristics considered in this study include board member size, board member gender diversity, board members educational qualification, industry specific experience, and board members sub audit committee size. The study controls the effect of size, leverage and growth of banks. The regression results show that large board size and audit committee negatively influences financial performance of sample private commercial banks in Ethiopia as measured by return on asset and return on equity; whereas board members educational qualification is significant and positively associated with financial performance. While industry specific experience of director positively related with return on equity but it has a negative effect on return on asset. Finally, the percentage of female directors does not have a significant effect. In general, the findings suggest that banks with effective corporate governance characteristics improve financial performance depending on the measure used although not all corporate governance characteristics are significant.
Natural world has a potentiality to manage all leaving beings across the globe. Near about 1.5 million species of plants, animal, fungi, algae, lichen are identified and documented on Earth and increasing day by day and there are currently about 75 billion tons of living things (bio mass) on earth (as per science line / ucsb data). As estimated about 8.7 million species (6.5 million are on land & 2.2 million in oceans) are present in earth, among which 1.3 million species are involve in give or take processes. Triglyceride encourages the function of providing energy, whereas cholesterol is needed by the human body for hormone synthesis and cellular structure which is a part of lipids is the major form of fatty acid combine with a molecule of alcohol and glycerol. It serves as the backbone of many types of lipids comes from the food we eat as well as form in the body digestion processes. In deficiency of this, several diseases are occurring in our body such as Hyperthyroidism refers to an overactive thyroid. The thyroid gland overproduces hormones, leading to sudden weight loss, increase in appetite, sweating, menstrual changes, fatigue, and sleeping problems. Apart from this low triglyceride in human body also caused due to malnutrition and results in cancer, memory loss, depression, inability to eat, and trauma. Deplete of fat, leading to low triglycerides which is caused due to use of certain kind of medicines and drugs and its side effects after use. Research finding of low triglycerides can be associated with its own range of adverse effects resulting in various health complications. Recent studies have found that, low triglyceride levels causes with old age and a high class of NYHA heart failure, decrease in resistance power & immunity to COVID - 19 in our body and also creates cardiac problem and even stroke. This emphasizes that importance of having an overall balance within the body, as high triglycerides have been known for leading the development of fatal cardiac and stroke issues as well. Low levels of triglycerides also impact other processes in the body such as the absorption of fat-soluble vitamins A, D, E, and K. These vitamins are involved in everything from the recycling of calcium to the production of beneficial blood clots. Omega-3 fatty acids are one type of essential lipid found in fatty fish, such as tuna, salmon and halibut. Omega β 3 fatty acids such as Eicosapentaenoic acid (EPA), Docosapentaenoic acid (DPA) and Docosahexaenoic acid (DHA) precursors of certain eicosanoids that are known to reduce inflammation in the body and improve hypertriglyverdemia. In plants it is found as Alpha Linolenic Acid (ALA), horticulture such as chia seeds, brussels sprouts, algal oil, hemp seed, walnuts, flax seeds, perilla oil, kidney beans, soyabean oil, seaweed, tender soya bean, fruits, olive leaf, Kale, broccoli, navy beans, winter squash, Egg yolk, wheat germs, pumpkin seeds, Red lettuce, spinach etc. These lipids are essential to maintaining proper brain function and may reduce inflammation in our body. Meeting our needs for essential fatty acids may also help reduce our risk of developing heart diseases, cancer and arthritis (Source University of Maryland Medical Centre). Again by using the essential lipids both derived from fishes & horticultural/agricultural plants will results in resistant to pandemic diseases like COVID β 19 cause by CORONA virus, aquatic air borne viruses & viruses transmitted through various vectors. It is better to use agriculturally found Triglycerides (ALA) with natural vegetable base insulinβs and fish base EPA, DPA & DHA derived Omega natural food supplements to protect our self from diseases like CORONA virus chain, Mental disorders, eye related night blindness, Overweight, skin diseases, MMR & life to child in pregnant women, children related deficiency cause low attention and hyperactivity, liver fat, depression, mental decline, asthma & allergy, bone growth related diseases, mal nutrition due to deficiency of added vitamins like A, D, E, K & B vitamin chain. Regular consumption of 0.2 β 0.5 gm omega extract rich fruits & vegetables, egg, processed meat, fish, milk derived from both animal & botanical sources and agronomical crop produce such as wheat, rice (black rice) & other cereals processed food can give us better health for bright future of our family as well as nation. The effectiveness of the natural triglycerides will depend on avoid of alcohols such as liquors and other related toxic rich commodity.
HIV patients who are taking Efavirenz experienced high-level of nightmare distress as a neuropsychiatric side effect of the drug. They underwent a 4-week Exercise Physiological Intervention Program, which comprised of basic yoga and physical fitness exercise. This kind of intervention program was proven to regulate the central nervous system, particularly the hypothalamic Βpituitary Βadrenal (HPA) axis activity. The HPA Axis is responsible for relaxing the brain activity for stressors and various kinds of anxiety, and it can further minimize the nightmare activity of the brain. The Respondents had the Nightmare Distress Questionnaire for pre-test and post-test analysis to the Exercise Physiological Intervention Program. The pre-test showed a high level (3.89) of nightmare distress, and the post-test showed a moderate level (3.14) of nightmare distress. The paired sample t-test result showed that there is a significant difference between the pre-test and post-test and asserts that the proposed intervention program is effective.

This study is an evaluation of the financial performance and corporate governance structures of Savings and credit cooperatives (SACCO), a case study for the Women Network Savings Credit Cooperative Society in the Zimbabwe Republic Police, Bulawayo Central District in Zimbabwe. The research set out to determine the relationship between corporate governance and financial performance of the SACCO. A sample of 48 was drawn from a population of 688 participants. comprising of 680 SACCO members, 4 Ministry of Youth and 4 National Association of Credit Savings Union of Zimbabwe (NACSCUZ) officials respectively. Questionnaires were distributed using drop and pick method to the 40 SACCO members and the interview was also used on Ministry and (NACSCUZ) officials. Data was collected and analysed using qualitative data analysis method. Findings revealed that the SACCO was found to comply less with corporate governance guidelines. corporate governance and financial performance were found to be strongly positively correlated. The study concluded that less compliance with corporate governance explain the relatively poor financial performance of this SACCO. The SACCO was therefore advised to create awareness amongst the members regarding their rights as well as encourage the SACCO to adhere to corporate governance principles, process and procedures among others.
The purpose of this research is to identify the optimum concentration of fermented rabbit urine as the alternative for the Pro Analysis fertilizer to increase the growth of S. fusiformis population. Four treatments of rabbit urine concentration used were 4ml/L (treatment A), 6 ml/L (treatment B), 8 ml/L (treatment C) and Zarrouk medium (treatment D, as the control). The design of this research used complete randomized design (CRD) with four treatments and three replications. The highest density average of S. fusiformis cell at its peak of growth is treatment D (190.723 x 10βΆ cell/ml), followed by treatment B (172.120 x 10βΆ cell/ml), treatment A (151.637 x 10βΆ cell/ml), and treatment C (140.800 x 10βΆ cell/ml). Treatment B (6 ml/L) was not significantly different with treatment D (control) based on the Duncan test (p > 0.05). The treatment B (6 ml/L) cell density average at the peak of population are 94,27 % from treatment D (control/Pro Analysis fertilizer). The growth phases (lag phase, exponential phase, stationary phase, and declination phase) of each treatments happened equally and at the same time interval. Rabbit urine serves as an alternative for the Pro Analysis fertilizer for cultivating S. fusiformis needed by herbivorous fish larvae.
A survey on time performance of diο¬erent types of construction projects was conducted to determine the causes of delay and their importance according to each of the project participants, i.e., the owner, consultant and the contractor. The field survey conducted included 23 contractors, 19 consultants, and 15 owners. Seventy-three causes of delay were identified during the research. 76% of the contractors and 56% of the consultants indicated that average of time overrun is between 10% and 30% of the original duration. The most common cause of delay identified by all the three parties is ββchange orderββ. Surveys concluded that 70% of projects experienced time overrun and found that 45 out of 76 projects considered were delayed. On the other hand, cost overruns for drainage projects decreased with increasing contract prices. A significant effort was spent in collecting data on cost overruns and delays in public construction projects. However, data confidentiality did allow the collection of enough data to ensure the robustness of the developed regression prediction models.
The study assessed the managerial communication skills possessed by principals for administrative effectiveness in public secondary schools in Enugu State. Three research questions guided the study and three null hypotheses were tested at 0.05 level of significance. The descriptive survey research design was adopted for the study. A sample size of 1485 consisting 285 principals and 1200 teachers were drawn using multi-stage sampling technique. Questionnaire instrument titled βManagerial Communication Skills Inventoryβ (MCSI) adapted from Ogbo (2010) was utilized for data collection. The instrument was validated by three experts and subjected to internal consistency test using Cronbachβs alpha method which yielded a reliability coefficient of 0.80. Mean and t-test were used to answer the research questions and hypotheses. The findings of the study indicated among others that principals of public secondary schools in Enugu state possess two of the five electronic communication skills for administrative effectiveness. They are: sending messages to teachers and parents through mobile phone and storing and retrieving school records and students results from computer. Principals possess only one of the four creativity communication skills for administrative effectiveness which is initiating new things as new ideas come into their minds. There was no significant difference in the mean ratings of principals and teachers on the electronic and creativity communication skills possessed by principals for administrative effectiveness. Based on the findings, it was recommended among others things that the State Education Commission should ensure that only teachers who possess relevant communication skills and are capable of communicating effectively are appointment as principals. This will help maintain a crop of principals with managerial communication skills in secondary schools in the state.
This comprehensive review intended to identify current technology advancement in dairy camel production. This review was uncovered that numbers of countries were hosted camel has been progressed on technology advancement in camel genetics, breeding techniques; production and reproduction technology; milk and milk processing; meat production, and other benefits of the camel. However, in Ethiopia, lack of adequate infor-mation that indicates those technologies have been tested. On the contrary, the camel was not even got at-tention from policymakers and other concerned stakeholders in comparison with other domestic animals (cat-tle, goat, sheep, and equines, etc.). Camel is now becoming the key animal among domestic species where different countries were understood the multipurpose of camel and it is products. The high demand for camel across the world population could be challenges for the producers to equal response for boomed demand for the camelsβ products in terms of quality and quantity. It has been noted that transferring existing camel pro-duction technologies could be one option to reach the increased demand particularly camels are natural very slow reproduction performance because of the seasonal breeding calendar and natural mating habits. So it could be a priority for Ethiopia to adopt those technologies to improve the production and productivity of camels that put the country in third place among African countries. This review was noted that Ethiopia should learn or upscale technology advancement of camels in the production system, milk processing, reproduction, breeding, and genetics. Now it is the right time to think at policy level on camel production and looks for the further fund to conduct research on camel technology advancements and disseminate the findings could be an assignment for researcher and academicians. Therefore, it is much more important to undertake further investigations on the findings to supplement this conclusion
Effective and efficient emergency management and response requires having the right information within the shortest possible time frame in order to save lives and property, this also involves the free flow of the right information in the right format, to the right person, in the right time to make the right decision. Information required to deal with an emergency event is of spatial origin and Geoinformatics have been known since its inception in the early 60s to handle time related spatial information. Emergency management is a national concern, at the most basic level it is the responsibility of the state emergency management agencies to respond effectively and efficient to any emergency situation. The aim of this research is to evaluate benefits of the use of Geoinformatics technology in emergency management to assist in planning and acting as a decision support system to Fire emergency managers. In this research, Rivers state fire stations were evaluated as units of emergency delivery system, the research examined the role of Geoinformatics in evaluating the performance of emergency fire service delivery based on response time and fire station distribution. Using ArcGIS Network analysis and an annual fire incident record from the year 2000-2012, the study revealed that the functional fire stations operating in Rivers state were unable to cover the entire populated regions within 5 minutes response time. In the case of this research the primary question that was addressed was; "Does everyone have access to rescue services within five minutes of travel time?" The GIS location-allocation and Network analysis tools were deployed to address these issues, and by doing so the technology was used to address issues of equity framed by the values of efficiency and effectiveness. Using the ArcGIS Network analysis tools the research was able to evaluate and assess the nature and performance of the Rivers State fire emergency services. One vital discovery was that fire service coverage analysis within 5-minutes response in the study area generated many gaps depriving the populated region of the state 5-minutes response coverage thus making such region highly vulnerable to loss of lives and properties in event of a fire inccident. The research concluded by proposing the location of three fire stations using location allocation tool to help reduce the burden of other fire station and ensured ninety five percent (95%) wider coverage and reduced response time. This research also recommended that more efforts should be channeled towards curbing the practice of illegal and crude ways of refining petroleum products in the state; hence the result of the partial correlation of the variables associated with causes of fire incidents in Rivers State indicates a huge influence of kerosene explosion on fire incidents in Rivers state.

Background: Coronaviruses are a tremendous family of viruses that can be an etiologic agent to cause a variety of diseases in humans, which can lead to complications ranging from mild to severe life-threatening conditions. In late December 2019, numerous patients with viral pneumonia were found to be related to the Huanan seafood market in Wuhan, in the Hubei province of China. Due to the rapid spread of COVID-19 infection globally, the World Health Organization (WHO) declared that COVID-19 infection as global pandemic disease on March 11, 2020. After two days, the first case was reported in Ethiopia. Objectives: To assess the knowledge, attitude, and practice towards COVID-19 infection in Arba Minch town, Southern Ethiopia. Methods: A cross-sectional survey was carried out at Arba Minch town from March 08 to April 08, 2020. Data were collected using a pre-tested interviewer-administered questionnaire technique and an online survey. The knowledge questionnaire consisted of 15 questions regarding the transmission, clinical characteristics, and prevention of COVID-19. Attitude and practice questionnaire consisted of 6 and 7 questions, respectively. Data were coded and entered into SPSS-for windows version 24 for analysis. Bivariate logistic regression analysis was done to determine the presence and degree of association between KAP and socio-demographic variables. Odds Ratios (OR) with 95% confidence intervals were calculated. In addition, multivariate logistic regression analysis was applied for knowledge and a statistical significance test was declared at P-value <0.05 and adjusted OR (AOR) with 95% CI. Results: A total of 528 participants completed the survey questionnaire, of these, 392 (74.2%) were male. The mean (SD) of the COVID-19 knowledge score was 11.48 (SD: 2.25, range: 1-15), suggesting an overall 76.53% [(11.48β15)Γ100] correct rate. About 408(77.3%) of participants had confidence in WHO could win the battle against COVID-19. One hundred twelve (21.2%) of respondents opposed the wearing of face masks. Among the study participants, 33.3% of respondents had at least one risk behavior related to COVID-19 infection. Multivariate logistic regression showed that age group of β₯40 years (AOR=13.2; 95%CI: 3.83, 45.64) (vs. β€21 years), marital status of married (vs. single) (AOR=0.35; 95%CI: 0.19-0.67), education levels of degree or higher (vs. primary school and below) (AOR=7.33; 95%CI: 2.2-24.23), and occupation status of government-employed (vs. students) (AOR=0.24; 95%CI: 0.1-0.60) were significantly associated with knowledge of COVID-19. Gender (being male) and age (<20 years) are more likely to engage in risk-taking behaviors. A higher knowledge score was possessed a positive attitude and proactive practice towards COVID-19. Conclusion: The findings showed the majority of respondents had good knowledge, a positive attitude, and less risky behavior toward COVID-19, but there are some negative attitudes, and risky behavior than expected. Especially, respondents had very reckless practices; going to a crowded place and not wearing a mask when leaving home. Health education programs aimed at improving COVID-19 knowledge are helpful to reduce risky behavior and maintain appropriate practices. Keywords: Coronavirus, COVID-19 infection, Knowledge, Attitude, Practice
The article discusses the role of sensory marketing in driving advertisement effectiveness. Current development of sensory marketing indicates the emergence of a new era in the field of marketing: and era in which the five senses of consumers will be the focus of marketing strategies and techniques. This paper focuses in the field of marketing giving attention to the five senses (sight, smell, hearing, taste, touch). The findings indicated that the five senses simultaneously affect the consumer behaviour. From a managerial perspective, sensory marketing can be used to create subconscious triggers that define consumer perception of abstract notions of the product (e.g., itβs sophistication, quality, elegance, innovativeness, modernity, interactivity) the brandβs personality. Thus, the result indicates that strategic stimulation of the senses of the consumer in marketing process can be one of the practical methods od companies and retailers to attract customers and increase their loyalty.
Two types of processing methods for Obiolor produced from sorghum and millet grains were investigated namely: wet-milled and flour-milled prepared Obiolor. Study of their physico-chemical, nutritional and antinutritional components were evaluated for improved production and nutritional enhancement. Proximate parameters determined were percentage moisture, ash, fat, crude fibre, crude protein and carbohydrate. Antinutritional contents such as phytic acid and trypsin inhibitor were evaluated as well as physico-chemical analysis such as pH, total titratable acidity (TTA), total soluble solids (TSS) and specific gravity. Obiolor produced from wet-milled process had 74.41Β±0.15% moisture, 2.86Β±0.00% ash, 5.20Β±0.02% fat, 1.75Β±0.25% crude fibre, 3.89Β±0.04% crude protein and 11.10Β±0.22% carbohydrate. Obiolor from flour-milled process had moisture content of 71.79Β±0.00%, ash content of 1.42Β±0.00%, fat content of 5.38Β±0.12%, crude fibre of 3.50Β±0.50%, crude protein of 4.40Β±0.01% and carbohydrate content of 13.52Β±0.60%. Antinutritional component in the traditional fermented beverages showed that phytic acid was 1.20 mgβ100g and 1.00 mgβ100g while trypsin inhibitor had values of 3.426 mgβ100g and 3.488 mgβ100g for both wet and flour milled prepared beverage. There was a fall in pH with a corresponding increase in total titratable acidity during the fermentation period. Total soluble solids and specific gravity were also determined. The various studied parameters indicated that flour-milled prepared Obiolor is of a better nutritional and physico-chemical attributes as compared to wet-milled prepared Obiolor.
Induction motors are the most widely used electrical motors due to their reliability, low cost and robustness. However, induction motors do not inherently have the capability of variable speed operation and high starting current. Starting large motors, especially across-the-line, can cause severe disturbances to other motors and any locally connected load and connected electrically. Ideally, a motor-starting study should be made before a large motor is purchase. The aim of this research is to perform analysis of a three-phase induction motor on different starting methods. Several staring method of induction motor such as variable resistance method, variable frequency method, variable voltage method and variable frequency voltage method was studied. The study was conducted on a 1HP, 3-phase, 415V, 50Hz, 4 poles induction motor; and simulated using an Engineering tool, MATLAB/Simulink, based on analytical technique. Amongst the induction motor starting methods considered, variable voltage frequency (V/F) produced a better result. In this method, by use of rectifier and Pulse Width Modulation (PWM) inverter, the supply voltage as well as the supply frequency is varied such that the ratio remains constant as well as the flux. in doing this, the maximum torque remains unchanged and different operating zone for various speeds and torques are achieved as well as different synchronous speed with almost same maximum torque. With this method, the starting torque of the motor was improved to 18N-m compared to the variable resistor method which has about 2.4N-m when the motor was started with highest resistance. The speed of the motor with V/F method was also obtained to be close to the motor reference speed, which is 1500RPM, while the speed for variable resistance method is 160RPM. The machine with V/F also has reduced starting current of about 20 Amps compared to the variable resistance method which has high starting current of about 400 Amps. Hence, it is recommended that during starting of the induction motor, the stator resistance and the motor inductance (both rotor and stator) must be kept low to reduce the steady state time and also to reduce the jerks during starting caused by inrush current.

Research data collection was carried out through an online questionnaire. This study utilizes 3 analysis tools, which are logistic regression analysis, independent sample t-test, and ANOVA analysis. There are 3 findings in this study. First, the result demonstrate a negative effect of religiosity perception towards switching behav-ior, while financial literacy, shariah literacy and financial technology demonstrate a positive and significant effect towards switching behav-ior. Second, the results also showed a significant difference of perception between Shariah banking customers and conventional banking customers towards financial literacy and shariah literacy, while the opposite occured to religiosity perception and financial technology. Third, the study revealed that the perception of 2 banking customer groups (shariah and conventional) towards banking religiosity is not different, but when compared to the group of Islamic banking employees, a lage gap was discovered.
One major problem faced in the aquatic environment is that posed by persistent organic pollutants (POPs). The evaluation of Persistent Organic Pollutant (POPs) in the gills and liver of fish (Tilapia sp.) was reported based on the analysis of samples which were collected on monthly basis for three months (October-December 2015). The samples were collected from three stations; station 1 (ST 1) and station 2 (ST 2) in Azuabie creek and station 3 (ST 3) in Okujagu creek which served as the control station. Samples that included gills and liver from fish were examined for POPs such as Aldrin, Pentachlorobenzene etc. In-situ analysis of water sample from the three stations was carried out for Physicochemical characteristics such as temperature, pH, dissolved oxygen, total dissolved solids and total suspended solids while POPS were analyzed using liquid-liquid extraction gas chromatographic method 1 (LL-EGC). Results of the physicochemical parameters showed that most of the parameters exceeded the United Nations Environmental Protection Agency (USEPA) and Federal ministry of Environment (FMEnv) permissible limits. The result obtained for turbidity which ranged from 0.89 to 20 NTU was within FMEnv limit for turbidity which is 10.0 NTU. Others such as pH, Oxidation reduction Potential, temperature, salinity did not exceed the USEPA permissible limit. Sulphate ranged between 290 to 417.7ppm exceeding the FMEnv permissible limit of 250ppm while total Nitrogen and nitrate were below FMEnv permissible limit of 4 and 10ppm respectively. For POPs, the results obtained ranged from 0.000 to 0.03 mg/kg across the stations while the POP result from the analysis of fish were not in agreement with National Oceanic Atmospheric Administration (NOAA) limit of 0.01mg/kg for fish. This was evinced on the fish liver collected at station 1 which had a concentration of 0.0123 mg/kg and it has the highest concentration of the pollutant tested. This was attributable to the high level of activities at the abattoir which includes animal dungs, blood spill from slaughtered animal, animal skin and bones. The station 3 is the control station (Okujagu creek) and it had the least concentration of most of the pollutants tested. The presence of these POPs constitute an ecological risk to the water ecosystem and consequently to human health. This has also led to differences in the quality of water and fish from the creeks. Therefore, there is need for preventive measures such as continuous check, government intervention and creating awareness both so as to reduce and control pollution of the aquatic environment.

Since this pandemic is our new normal and is here to remain for a little while longer , until the immunisation is created and given to everyone . so , it is absolutely devastating for us to switch of the news channel every now and then to see the statistics always rise of the covid patients, so letβs now consciously remind yourself , whenever you feel like questioning the circumstances around you that the world has endured so many pandemics in the past , and therefore this too shall pass.
