Software reuse can improve software quality with the reducing cost and development time. Systematic reuse plan enhances cohesion and reduces coupling for better testability and maintainability. Software reuse approach can be adopted at the highest extent if relevant software components can be easily searched, adapted and integrated into new system. Large software industries hold their own well managed component libraries containing well tested software component with the project category based classification .Access to these repositories are very limited. Software reuse is facing so many problems and still not so popular. This is due to issues of general access, efficient search and adoption of software component. This paper propose a framework which resolves all of the above issues with providing easy access to components, efficient incremental semantics based search, repository management, versioning of components.

Agriculture has one of the highest shares of foreign-born and unauthorized workers among US industries; over three-fourths of hired farm workers were born abroad, usually in Mexico, and over half of all farm workers are unauthorized. Farm employers are among the few to openly acknowledge their dependence on migrant and unauthorized workers, and they oppose efforts to reduce unauthorized migration unless the government legalizes currently illegal farm workers or provides easy access to legal guest workers. The effects of migrants on agricultural competitiveness are mixed. On the one hand, wages held down by migrants keep labour-intensive commodities competitive in the short run, but the fact that most labour-intensive commodities are shipped long distances means that long-run US competitiveness may be eroded as US farmers have fewer incentives to develop labour-saving and productivity-improving methods of farming and production in lower-wage countries expands.

The research objective describes an integrated marketing communication strategy in developing Sakura Syariah Hotel to see a comprehensive marketing communication strategy. Hotel Sakura Syariah is a 3-star syariah concept hotel which has 70 rooms. The analytical method uses the 7P (marketing mix) approach. The research results to increase the number of guests staying the strategy consisted of products, which offer a sharia concept with various types of representative rooms. Pricing, using the appropriate price preferences. Place, hotel location that is close to the center of the district capital and easy access. Promotion, with direct selling in accordance with local government and private selling by participating in various marketing events, sales proposals and advertising. People, conduct trainings to improve human resource capabilities. Physical evidence, a physical building that has Sharia characters and is supported by fairly good technology. Process, reservation service is quite fast and excellent. The development of this Sayriah hotel must be supported by related parties, especially the local government in order to increase the number of hotel guests
