This paper outlines the system and operation of plant variety protection right and plant patent of ornamental crops in USA to guide for application of new varieties developed in Korea and to use for national examination of applied variety from USA. The Plant Variety Protection Act(PVPA) in USA is given as PVPR to the developers of new variety for the seed propagating crops and tubers and provides as plant patent for asexually reproducing crops. A certificate of PVPR and plant patent is awarded to an owner of a variety has shown that it is new, distinct from other varieties, genetically uniform and stable through successive generations by official evaluation without the growing trial. The term of protection for plant patent and PVPR for most crops is 20 years but 25 years for trees, shrubs, and vines. The application of ornamental variety in USA is mostly for plant patent. The application of ornamental crops accounted for 87% of total applications for plant patent. The ratio of new variety applications for plant patent from national and foreign countries is not significant differences.

As the international construction market is rapidly expanding, Korean contractors have the need for having new leading businesses for their sustainable growth and high performance. Thus, this research tried to explore new leading businesses with two questions: 'What can be the new leading businesses?' and 'How can Korean contractors implement new leading businesses?' To this end, based on Porter's five forces framework and the resource-based view (RBV), we first derive three evaluation criteria (possibility of market entry, possibility of profit earning, and possibility of value-added earning). Next, we developed a framework for business evaluation which considers external market condition, internal competitiveness, and spin-off effects toward domestic market. Based on the framework, we defined green-energy plant, environmental plant, desalination plant, nuclear power plant, new urban development, and high-rise building as new leading business. Then, we selected green energy plant, environmental plant, and new urban development for the purpose of prior occupation of the market, consolidation of the competitiveness, and expansion of the ripple effect, respectively. Finally, we deduced market entry strategies for each business by investigating experts' opinions.

The gas stripper system of a nuclear power plant provides gas-free water to a reactor and a turbine system. The gas tripper unit has two control systems to regulate pressure and level independently. Because the level and the pressure interact as a control disturbance each other, continuous operation of the system is difficult. In this paper, We describe the controllability evaluation of the gas stripper system and the results of the optimally tuned control gains.

Finishing materials are very important to restrain fire spread from a compartment to another in a fire situation. Therefore, the evaluation of combustible properties for the combustible material is essential to apply finishing materials into a generic buillding or s special occupancy structure. In this study, the testing methods for evaluation of combustible performance of finishing materials of domestic were surveyed in order to prepare the guideline of application of finishing materials in nulear power plant.
