    Agriculture remains the major livelihood in most of the developing countries in Asian and Pacific region even at present. One of the major problems among the farmers of developing countries is the lack of knowledge of the market of their products. Farmer's participation in market is poor and they are being forced to sell their products to local middlemen at dumped prices. The Agricultural Market Information System with Integrated Forecasting and Short Message Service (SMS) Accessibility project presents an Information and Communication Technology (ICT) solution to the problem by giving the timely and unbiased Agricultural Marketing Information. It helps farmers to gain profitable decisions in the short term on when and which market to produce, what price to produce and what price to expect. A GSM modem and an SMS Gateway application are used to send and receive the SMS messages. The Time series algorithm model was constructed to forecast the agricultural products' market prices. Through the empirical data testing, the average relative error was 2.91% for Samba Rice, which shows that this model can achieve good predicted results. This time series forecasting model can be used in forecasting the prices of various types of agricultural products, with a premise that having enough data of agricultural products in the model training to determine the model structure and parameters.

Widu Suwa Sahana is a unique system compared to available systems. It can be used in all categories of hospitals in Sri Lanka. Because of the business logics the system is rich in flexibility, adaptability and user friendliness. There is no need of a skilled person to operate the system. Therefore anybody can use the system according to the permissions given. Fewer amounts of inputs have to be included for regular users while other inputs are handled by the system automatically. Finally, patients' history can be used for prediction purposes as well as for doctors to take better decisions on the patients. Patients do not need to travel for registration or examination of test reports. Short message service is used for necessary information and notification sending.
