Food-based approaches such as dietary diversification, nutrient retention and biofortification combined with nutrition education can be effective in eliminating micronutrient deficiencies. The objective of this study was to assess the nutrition knowledge and consumption practices as well as barriers to consumption with specific focus on food-based approaches to vitamin A and iron deficiencies prevention and to identify individual, community and governmental level strategies that may facilitate the adoption of these approaches. Using qualitative methods, one focus group (FG) discussion each was conducted with members of the Cocoa Farmers' Cooperatives in each of the 25 rural communities in the Amansie West and Asunafo North Districts in Ghana. Findings showed participants in only 3 FGs had knowledge of vitamin A and its deficiency diseases while only 2 FGs had knowledge of foods that could prevent vitamin A deficiency. Participants in 23 FGs were aware of the occurrence of iron deficiency anaemia especially in pregnant women; however, only 8 FGs had knowledge of the causes of anaemia. Furthermore, all the 25 FGs mentioned the use of haematinics in the treatment and prevention of anaemia but only 4 FGs knew about the use of food-based approaches. Various types of animal products, vegetables, fruits, and legumes, which are useful in preventing vitamin A and iron deficiencies, were found to be available in the communities. However, participants in all the 25 FGs indicated that the consumption of these foods particularly dark-green leafy vegetables has been dwindling with time. The FG participants mentioned a number of barriers to consumption of these foods and they include inadequate knowledge of nutritional value of the foods, lack of cooking skill, low production levels, laziness, conflicting media reports, lack of storage facilities, and contamination with agrochemicals. Findings imply that nutrition interventions should focus on education and awareness creation and implementation of strategies that can remove consumption barriers and facilitate the adoption of food-based approaches for managing micronutrient deficiencies.

Background: Occupational risk management is known as a catalyst in generating superior returns for all stakeholders on a sustainable basis. A number of companies in Ghana implemented health and safety measures adopted from international companies to ensure the safety of their employees. However, there exist great threats to employees' safety in these companies. The purpose of this paper is to investigate the level of compliance of Occupational Health and Safety management systems and standards set by international and local legislation in power producing companies in Ghana. Methods: The methodology is conducted by administering questionnaires and in-depth interviews as measuring instruments. A random sampling technique was applied to 60 respondents; only 50 respondents returned their responses. The questionnaire was developed from a literature review and contained questions and items relevant to the initial research problem. A factor analysis was also carried out to investigate the influence of some variables on safety in general. Results: Results showed that the significant factors that influence the safety of employees at the hydroelectric power plant stations are: lack of training and supervision, non-observance of safe work procedures, lack of management commitment, and lack of periodical check on machine operations. The study pointed out the safety loopholes and therefore helped improve the health and safety measures of employees in the selected company by providing effective recommendations. Conclusion: The implementation of the proposed recommendations in this paper, would lead to the prevention of work-related injuries and illnesses of employees as well as property damage and incidents in hydroelectric power plants. The recommendations may equally be considered as benchmark for the Safety and Health Management System with international standards. © 2016 The Authors.

To realize the self-control of the intelligent underwater robot, first of all is to have an independent visual system and the positioning system. Through the visual system, the robot can obtain the underwater environment information, providing the guidance for its movement and underwater works. The vision system of the intelligent underwater robot relies mainly on the "acoustic vision". The acoustic vision system not only has the acquisition ability of acoustic image and acoustic information, but also processes functions include image and information processing, feature extraction, classification and identification. Meanwhile, the positioning and map building are research hotspot in robot technology field, which is also the key to achieve truly autonomous robot. This paper uses the Super Seaking DST forward-looking sonar to scan the underwater environment and get the sonar image which is needed by the simulation program, and applies the digital image processing method into the sonar image, having processes such as filtering, smoothing, segmentation and so on to the sonar image, extracting the target characteristics and linear characteristics, getting the characteristics map of the underwater environment, constructing the characteristics map simulation platform based on the environmental characteristics, realizing the autonomous positioning and navigation simulation of the AUV by using EKF SLAM algorithm, and having an analysis on AUV movement tracks under the different environmental characteristics and on causes for errors.

Monetization of personal identity information has become a major component of modern business models, driving innovation in many industries. This phenomena is common place given that parties to business transactions and social interactions usually rely on the issue of claims, and disclosure of unique attributes and credentials for proofs and verification of identity. However, the heightened societal information privacy concerns, and the diminishing level of trust between transacting parties' makes such attempts to monetize personal information a very risky endeavor given the dearth of literature in that regard. This study focuses on understanding the major technological and regulatory imperatives in the monetization of personal identity information. Focus group discussion and interviews in four major cities in Ghana were the sources of empirical evidence which supports the claims made in this paper. The resulting monetization model provides a critical reference point for technological and regulatory policies that ensure effective monetization of personal information. © 2015 IEEE.

For a sustainable economic development, premium fuel forecasting is becoming increasingly relevant to policy makers and consumers. The current paper develops a structural econometric model of premium fuel using the autoregressive integrated moving average (ARIMA) to analyse and forecast premium demand. The results show that the ARIMA models (1, 1, 0); (0, 1, 1) and (1, 1, 1) are the appropriate identified order. The estimated models included a constant term. All the coefficients of the variables in the model except the constant term were significant. The diagnostic checking of the estimated model shows ARIMA (1, 1, 1) as the best fitted model since all the series were randomly distributed. The data for the forecast covers the period 2000:01 to 2011:12. The results indicated that the forecasted values fitted the actual consumption of the energy variables since the forecasted values insignificantly underestimate the actual consumption and thus indicate consistency of the results. The evaluation statistics indicate that the estimated models are suitable for forecasting. The model developed in the work is helpful to the energy sector and policy makers in making energy related decisions and investigating the changes in premium demand. © 2015, Econjournals.

The practical success of association rule mining depends heavily on the criterion to choose among the many rules often mined. Many rule quality measures exist in the literature. We propose a protocol to evaluate the evaluation measures themselves. For each association rule, we measure the improvement in accuracy that a commonly used predictor can obtain from an additional feature, constructed according to the exceptions to the rule. We select a reference set of rules that are helpful in this sense. Then, our evaluation method takes into account both how many of these helpful rules are found near the top rules for a given quality measure, and how near the top they are. We focus on seven association rule quality measures. Our experiments indicate that multiplicative improvement and (to a lesser extent) support and leverage (a.k.a. weighted relative accuracy) tend to obtain better results than the other measures. © 2013 Springer-Verlag.

In Ghana, out-of-home ready-to-eat foods including fast food generally have been associated with food safety problems. Notwithstanding, fast food production and consumption are increasing in Ghana and therefore this study sought to determine the food safety issues of importance to consumers and the extent to which they worry about them. First, through three focus group discussions on consumers' personal opinions about food safety issues, some emergent themes were obtained, which were used to construct an open-ended questionnaire administered face-to-face to 425 respondents systematically sampled from 20 fast food restaurants in Accra. Findings showed that most fast food consumers were concerned about food hazards such as pesticide residue in vegetables, excessive use of artificial flavour enhancers and colouring substances, bacterial contamination, migrated harmful substances from plastic packages, and general unhygienic conditions under which food is prepared and sold. Consumers also raised concerns about foodborne diseases such as cholera, typhoid, food poisoning, diarrhoea, bird flu and swine flu. The logistic regression model showed that being male increased the likelihood of worrying about general food safety issues and excessive use of flavour enhancers than in females while being youthful increased the likelihood of being worried about typhoid fever than in older consumers. These findings imply that consumers in urban Ghana are aware and concerned about current trends of food safety and foodborne disease challenges in the country. Therefore, efforts targeted at improving food safety and reducing incidences of foodborne diseases should not only focus on public awareness creation but should also design more comprehensive programmes to ensure the making of food safety rules and guidelines and enforcing compliance to facilitate availability and consumers' choice of safe foods. © 2015 Elsevier Ltd.
