The objective of this study is to extend the Kim, Oh & Dwyer's technology transfer negotiation model and to examine the effects of country of origin of the seller on bargaining processes and outcomes in international technology transfer negotiations. More specifically, under the context of technology transfer negotiations between Korean buying firms and two advanced countries' technology suppliers, United States's and Japan's, we explore the effects of the acquiring firm's position in the business environment and capacity to absorb technology on the negotiated contractual terms for the transfer of technology. The research results indicate the Kim, Oh & Dwyer's (1991) negotiation model for technology transfer Is some applicable to the USA model , in which the USA technology supplier is the negot13tlon partner of the Korean buying firm, but not to the Japan model. More research on the Japan model has been needed.

To assess the potential as biofortified rice varieties, new endosperm and grain mutant lines were selected from M4 generation seeds of the rice cultivar Shindongjin, which were either γ-irradiated or treated with N-methyl-N-nitrosourea (MNU) and lipid, sugar, and tocopherol content were analyzed. Amylose content in non-waxy mutants ranged from 8.8% in SM-4, a dull-type mutant, to 29.5% in SM-51, compared to 18.9% in the parental variety, Shindongjin. SM-23, a floury-type mutant, contained 0.09 μg/g α-tocopherol (40.9% of total tocopherol), was three times higher than in the parental variety. SM-32, a giant embryo-type mutant, had a 2.2-fold higher total tocopherol content, 2.1-fold higher α-tocopherol, and 5.5-fold higher δ-tocopherol content (47.3% of total tocopherol) than the parental variety (0.13 μg/g). Total free sugar content was elevated in all selected mutants and 1.2-8.6 times higher than in the parental variety (11.38 μg/g). These increased sugar levels were due to increase in sucrose concentration. SM-23 (floury-type mutant) and SM-51 (high amylose-type mutant) had 4.6 and 7.0 times more sugar, respectively, than the parental variety (11.38 μg/g). With relatively high concentrations, most mutants showed elevated fatty acid content in the SM 32 (giant embryo-type) and SM-51 (high amylose-type) mutants, at 124.56 and 89.59 mg/g, respectively. All selected mutants displayed valuable characteristics for the development of new varieties in rice-breeding programs.

To facilitate an active breeding strategy for rice quality improvement, mutation were induced by treating rice variety Sindongjin seeds with gamma ray(300 Gray) and its fertilized eggs with MNU(1mM). Endosperm and grain shape of mutants were classified and selected in M2 population. From M2 generation, 48(7.6%) endosperm mutants and 179(11.9%) grain shape mutants were selected. White belly and White core were the most frequent. Selected grain mutants were classified into 16 types according to their morphological phenotypes. The overall segregation ratio was 3 : 1, controlled by one gene. Specially, SM-17 and SM-20 displayed segregation ratio of 9 : 7 and 1 : 15 respectively. Grain mutants showed generally earlier heading dates, shorter culm length and ear length than the parent. Grain length, grain width, and 1,000 grain weight were also mostly shorter and lower than the parent. In SEM analysis, each mutant type showed unique starch particle size and starch accumulation pattern. The density of polygonal cells and small inner corpuscles depending on amylose content decreased as following order - Waxy>Dull>Parent >White core. In SDS-PAGE analysis, SM-22 of Opaque group and SM-34 of Giant embryo group showed high glutelin polypeptide concentration. SM-23 of Floury group, SM-26 of Shrunken group, and SM-31 of Sugary group showed low concentration of total protein with variations in bands over 55kDa.

To assess the potential as biofortified rice varieties, new endosperm and grain mutant lines were selected from $M_4$ generation seeds of the rice cultivar Shindongjin, which were either $\gamma$-irradiated or treated with N-methyl-N-nitrosourea(MNU) and lipid, sugar, and tocopherol content were analyzed. Amylose content in non-waxy mutants ranged from 8.8% in SM-4, a dull-type mutant, to 29.5% in SM-51, compared to 18.9% in the parental variety, Shindongjin. SM-23, a floury-type mutant, contained 0.09 ${\mu}g/g$ $\alpha$-tocopherol(40.9% of total tocopherol), was three times higher than in the parental variety. SM-32, a giant embryo-type mutant, had a 2.2-fold higher total tocopherol content, 2.1-fold higher $\alpha$-tocopherol, and 5.5-fold higher $\delta$-tocopherol content(47.3% of total tocopherol) than the parental variety(0.13 ${\mu}g/g$). Total free sugar content was elevated in all selected mutants and 1.2-8.6 times higher than in the parental variety(11.38 ${\mu}g/g$). These increased sugar levels were due to increase in sucrose concentration. SM-23(floury-type mutant) and SM-51(high amylose-type mutant) had 4.6 and 7.0 times more sugar, respectively, than the parental variety(11.38 ${\mu}g/g$). With relatively high concentrations, most mutants showed elevated fatty acid content in the SM 32(giant embryo-type) and SM-51(high amylose-type) mutants, at 124.56 and 89.59 mg/g, respectively. All selected mutants displayed valuable characteristics for the development of new varieties in rice-breeding programs.
