Abstract

Data encryption is well known as essential for today?s technology. ElGamal encryption and RSA algorithmis made before storing mails to mail server. ElGamal decryption and RSA decryption is made after retrieving mailsfrom mail server. This system is implemented to secure mail server system for local government?s important mailmessages. These algorithms consume a considerable amount of time and resources of memory, CPU time, andcomputation time to encrypt and decrypt data. This paper discuss the results comparison of these algorithms in termof encryption time, decryption time, and memory usage over variable file sizes. The results show that RSA does fasterencryption process in compare with ElGamal. However, ElGamal decryption process is quicker than RSA. This systemis also expressed comparison of storage Size between RSA and ElGamal. Both of these algorithms are cryptographicpublic-key algorithms but have roles in different techniques. This system is using C# programming language and SQLServer to store mail messages.

Abstract

Organic farming and organic food market have been growing around the world for many years. In Myanmar, organic food is in the early stage for production and marketing. The study aims to analyse the determinants of the consumers’ purchase intention and attitudes toward organic food and the role of sociodemographic characteristics. The data was collected from 80 consumers of Nay Pyi Taw Region using structured questionnaires. The findings indicated that 38 percent of the respondents perceived that they were fully aware of organic food, organic agriculture and their differences with conventional food and agriculture. Among the respondents, 61 percent were willing to pay premium price for organic food. The results indicated that age and household size of the respondents were not significantly associated with the respondents’ awareness level of organic food, purchase intention, the premium price the respondents were willing to pay, expected consumption frequency in the future and checking before buying while these variables were positively associated with the education level of the respondents. These variables were also significantly different according to the respondents’ occupation types and residential places. Regression analysis predicted that the respondents’ income, ratio of food expense and income, education level, awareness level of organic food and the premium price they are willing to pay have significant impacts on their purchase intention in the future. The findings from this study contributed the importance of the respondents’ sociodemographic characteristics on purchase intention and attitudes toward organic food for further research.

Abstract

This paper empirically investigates the existence of economies of scale in food consumption, the share of food expense in total household expenditure, and the determinants of per capita food expenditure in Myanmar. The study was conducted with a total of 400 respondents from Nay Pyi Taw region and the survey took place in October 2021. The results are presented into two sections. In the first section, the descriptive statistics of the variables such as the respondents’ age, household size, education and residence are reported. The household monthly income was 227.51 USD, household monthly food expenditure was 112.49 USD, household monthly per capita food expenditure was 36.69 USD, and the share of food expenditure to total household expenditure was 70.20 % on average. In the second section, the inferential statistics of the variables are reported using the Pearson’s correlation analysis and regression analysis. Significant negative relationships were found between adult-equivalent household size and per capita food expenditure, and between income and the share of food expense in total household expenditure. The negative effect of household size on per capita food expenditure indicated by the regression analysis suggested that economies of scale in food consumption existed among the study households. Policy makers therefore need to consider economies of scale when designing the poverty alleviation programs.
