To achieve the purpose of this study 1000 girls and boys (age 10-17 years) selected from various provinces in Sri Lanka by random sampling method. The data were collected using the AAHPER test batteries which consist with six test items 50-yard run, standing broad jump, shuttle run, pull-up for boys and flex arm hang for girls, sit up and 600 yards run respectively and was analyzed by using SPSS. From the results, following percentile norms were created 5th 10th 15th 20t 25th 30th 35th 40th 45th 50th 55th 60th 65th 70th 75th 80th 85th 90th 95th 100th. From the results it was concluded that, newly constructed norms are slightly lower than AAHPER youth fitness test battery. Hence it was recommended that, newly constructed fitness norms are appropriate to categorize fitness level of the Sri Lankan youth. Further studies are essential to enhance the reliability and validity of the newly constructed norms.

Introduction of new plants is critical to the survival and profitability of the floricultural industries. These provide a marketing edge and can offer real benefits to fulfill special floriculture needs. Present survey was conducted to observe the potential of endemic Exacum spp. (Binara) as an ornamental plant among younger generation. The sample was selected from undergraduate students (n=125), Faculty of Agriculture, University of Ruhuna, Sri Lanka. Semi-structured interviews were carried out among the undergraduates representing all districts of Sri Lanka using a pre-tested questionnaire and showing a specimen of Binara plant. Group discussions were conducted with randomly selected students; 5 students/ group. Data were analyzed descriptively and presented with appropriate descriptive tools. The survey revealed that lack of awareness about Binara plant among the university students (66%) in most of the Districts of Sri Lanka. The results showed those respondents around 78% like to natural colour (blue-purple), actual flower size (50%),natural texture of flower petal (60%) and the height of the plant (70%) of the Binara flower. The respondents of 36% have not clear idea about vase-life of Binara flower. The respondents were more like to use Binara plant as potted plant (60%) than cut flower (40%). When considering the propagation of Binara, 58% respondents accept with propagation by seeds (58%) rather than asexual propagation (42%). However seed propagation of Exacum is hard in home level as its seeds are very small (110-140μm). Among vegetative propagation techniques, 68% respondents suggested to develop cutting than layering (42%).

Depending on recent records, the price of gold has been rising day by day more than the past; similar characteristics has been shown in Sri Lankan gold price as well. What would be the causes behind this? Basically, this study has been carried out on two levels. For first level, we constructed models to forecast monthly gold price. The data was mined form World Gold Council and Central Bank of Sri Lanka. The sample data of gold price were gathered from 2007 January to 2016 March in the currency of US dollars per troy ounce. It was converted into Sri Lankan rupees per 22 carats. 75% of data were used to build the model and remaining data were used to forecast the gold price and to check the accuracy of the model. Box-Jenkins, Auto Regressive Integrated Moving Average (ARIMA) methodology has been used to build forecasting models.
