BACKGROUND The medicinal plants and the associated Bhutanese traditional medicine (BTM) are protected by the country's constitution and receive both government support and acceptance by the wider public. More than 1000 medicinal plants are described in the BTM but currently collects only 300 species for daily formulations of BTM. These medicinal plants have been one of the drivers of the 'Gross...

OBJECTIVE Common mental disorders (CMDs) are a major cause of the global burden of disease. Bhutan was the first country in the world to focus on happiness as a state policy; however, little is known about the prevalence and risk factors of CMDs in this setting. We aim to identify socioeconomic, religious, spiritual and health factors associated with symptoms of CMDs. DESIGN AND SETTING We us...

In Data mining, Fuzzy clustering algorithms have demonstrated advantage over crisp clustering algorithms in dealing with the challenges posed by large collections of vague and uncertain natural data. This paper reviews concept of fuzzy logic and fuzzy clustering. The classical fuzzy c-means algorithm is presented and its limitations are highlighted. Based on the study of the fuzzy c-means algor...

We solve the problems of detecting and counting various forms of regularities in a string represented as a Straight Line Program (SLP). Given an SLP of size n that represents a string s of length N , our algorithm compute all runs and squares in s in O(nh) time and O(n) space, where h is the height of the derivation tree of the SLP. We also show an algorithm to compute all gapped-palindromes in...

Development is an inherent human desire, and the unique and dynamic concept of Gross National Happiness as a development philosophy and objective is generating substantial interest among many development partners of Bhutan. Nonetheless, some believe that development inevitably entails a negative effect on the mental well-being and happiness of the people. Others accept the premise that developm...
