Abstract:  The Southern Coast of Sri Lanka has been flooded with natural beauty with rich biodiversity attracted to the tourists for centuries. There is an uptrend of occupancy by foreign guest up to Galle and beyond after 2008. The increasing of night occupancy will increase the demand for tourism-related business. It creates competition of business and it causes the risk for their business. Therefore, this study was focused on forecasting foreign guest nights in Southern Coast of Sri Lanka to minimize the risk. Monthly data of foreign guest nights for the period of January 2008 to December 2016 were obtained from annual reports of 2008 -2016 published by SLTDA. At first descriptive statistics obtained and SARIMA model was tested for forecasting. The normality and randomness of residuals tested for model validation. Forecasting ability of the models was assessed by relative and absolute measurements of errors. On average night occupancy up to Galle and beyond are 131000 and 40298 respectively. ARIMA (1,0,0)(1,0,1)6 and ARIMA (1,0,0)(1,2,1)6 models satisfied the validation criterion. The study concluded that SARIMA performs well in forecasting night occupancy up to Galle and beyond in the Southern coast of Sri Lanka. Occupancy series follows wave-like pattern with trend. It may contain both seasonal and cyclical variation, but the SARIMA is unable to separate them. Therefore, it is recommended to test the Sama Circular Model, in order to see whether it improves the forecasting.

Abstract:In this paper, the harmonic part of the effective Hamiltonian operator  of the sixth degree, is taken with the group SU(2),and numerically studied. Two operators of creation and annihilation are used, and the energy levels from  to  are calculated and demonstrated, .Furthermore, the degree of decomposition is properly derived and, the semi-particle glonon is believed.

Abstract:As for many adolescents are not so educated, risky sexual behavior is one of the main unhealthy behaviors in which adolescents don’t know the risks of. Literature reveled risky sexual behaviour of adolescents is associated with source of knowledge and other factors associated with risky sexual behavior was age, parents and media.Chi square test, t-test, systematic kth case, logistic and poisson regression analytical techniques were techniques from literature.A sample of 101 randomly selected adolescents of public and private schools of Western Province of Sri Lanka. A self-administrated questionnaire was used for data collection. The questionnaire confirmed the reliability and validity.Both descriptive and inferential statistics used for data analysis. The Z-test and t-test test was used for hypothesis testing. The Z-test and t-test test was used for hypothesis testing. The descriptive statistics indicated that,7.9% of adolescents have taken part in risky sexual activities and around 50% of adolescents get their knowledge about sexuality from school. Inferential Statistics was obtained for proportion of adolescents who have taken part in risky sexual activities. The results show that the proportion male and female adolescents involved in risky sexual behaviour were equal. And risky sexual behaviour in public and private schools were equal. In conclusion, about half of adolescents get their source of knowledge about sexuality from school. And risky sexual behaviour between male and female adolescents, and public and private schools are not different. The results of this study can be taken for the prevention of adolescent’s risky sexual behavior.
