Purpose - Research on the ability of domestic public institutions to conduct business is being conducted. Research on government support policy for public technology projects, emphasizes technology creation. Public agencies are encouraging evolutionary barriers at the stage of realistic business. This paper presents the policy possibilities by presenting policies and strategies based on corporate public policy. Research design, data, and methodology – In this study, we surveyed the actual state of public technology commercialization based on the data on state of technology commercialization of public institutions. We collected and analyzed the literature data to enhance the competitiveness of technology commercialization by identifying success cases of public technology commercialization. In Korea, there are not many research papers that provide policy alternatives for technical commercialization of public research institutes. Therefore, in this paper, we review various government policies and check the status of technology commercialization to increase its value. Results – As a result of this study, it is suggested that various policy development is necessary for the commercialization of public technology, because it is important to increase the value of technology users, suppliers, investors and customers through various network activation. In particular, it is necessary to establish differentiated Korean public technology commercialization model for the proliferation of public technology commercialization by presenting methodical model of technical commercialization. Conclusions - Through this study, it is important to raise the competitiveness of domestic public technology commercialization, to create economic value, and to improve the performance of technology commercialization. Therefore, it is necessary to contribute to the creation of research achievement, research method of excellent technology, and method of commercializing technology, and to create achievement of technical commercialization in the future. In addition, from the viewpoint of commercialization of technology, strategies for creating value through utilization of public technology should be prepared, and a plan for mutual prosperity among domestic companies should be prepared. Policy alternatives of various public technology commercialization to build national competitiveness have been developed, and various examples of performance for the performance of public technology commercialization should be derived.

Daily shedding pattern and longevity of pollen are important consideration for the evaluation of gene flow of transgenic plants. During the day, the pollen shedding pattern of zoysiagrass was determined in the lawn by using a device to collect airborne pollen on a glass slide, resulting that the pollen grains were released predominantly between 7:00 and 9:00. The result was also supported by in vitro pollen germination test, which was performed with pollens collected from 1:00 through 24:00 at 1h interval. Influence of temperature and humidity on pollen longevity was determined by germinating pollen at 25°C after incubating them for 10, 30, 60, and 180 min under different temperatures and humidity with pollen of zoysiagrass that opened freshly at about 9:00. The result showed that pollen longevity of zoysiagrass was sensitive to change of temperature and humidity and longest under the temperture and humidity of 15-20°C and 80-99%, respectively. Under natural conditions with the same method as upper controlled conditions, was determined pollen longevity. Under sunny atmospheric conditions, pollen longevity decreased to 20% in 60 min, with a complete extinction in 120 min. Under cloudy atmospheric conditions, pollen remained viable up to 450 min, with about 20% longevity after 360 min. No significant difference was found between GM and non-GM plants in their pollen longevity.

Mosquitoes are carriers of malaria and encephalitis. This study performed for eco-friendly control of mosquitos by using genus Acorus. Several solvents were used for the extraction of genus Acorus; water, ethanol, and methanol. Grinded leaves and roots were also included. Acorus extracts killed mosquito larvae and the ethanol extract showed the best result. Autoclaved Acorus water needed long time to kill mosquito larvae. LT50 of 1 % Acorus calamus decoction was 13.6 hrs and 1 % autoclaved Acorus water was 53.6 hrs. LT50 of 0.05% Acorus calamus rhizome powder was 28.5 hrs. LT50 of 0.5% Acorus calamus leaf powder was 10.8 hrs. LT50 of 0.1 % Acorus calamus decoction was 63.4 hrs and 0.1 % Acorus calamus ethanol extracts was 48.6 hrs and 0.1% Acorus calamus methanol extracts was 53.9 hrs. LT50 of 0.4% Acorus gramineus decoction was 45.5 hrs, 0.4% ethanol extracts was 10.9 hrs, 0.4% methanol extracts was 10.2 hrs. LT50 of ethanol extracts was shorter than other extracts. Acorus calamus rhizome powder could be used for the eco-friendly control of the mosquito larvae.
