The purpose of this study is to explore the effect of the family ideology and inter-generational exchange on the level of parent-child relationship satisfaction. The major findings of this study are as fallow. First, middle aged generation show more traditional attitude than older generation in gender equity, attitudes toward divorce and marriage consciousness. Second, for the middle aged generation, there are significant differences in gender equity, attitudes on divorce and family ideology by gender. Emotional exchange is affected by education level and health status while service exchange is affected by occupation, income and health status. Parent-child relationship satisfaction are related with the gender, health status and religion of the middle-aged generation. Attitudes of older generation on the issue of gender equity, divorce and family ideology are also differ by gender. Emotional exchange is affected by marriage status and religion of the older generation. Age, marital status, occupation, and religion have significant impact on economic exchange. Third, parent-child relationship satisfaction of the middle aged generation are largely explained by the level of emotional exchange, attitudes toward divorce. The relationship satisfaction of the older generation are strongly related with the level of service exchange and emotional exchange.

The present study was conducted to estimate the antioxidant activities, physicochemical properties and biological activities in Beauveria bassiana. Glucose was the most abundant in B. bassiana (15.2 g?L?1) of 3 day medium by the HPLC analysis of free sugar. Citric acid were observed the highest components in B. bassiana (276.4 mg?L?1) of 3 day medium by the HPLC analysis of organic acid. The composition of Glutamate was the highest among amino acids in B. bassiana (987.0 pmol?μl?1) of 3 day medium. Na was the highest among minerals. It was focused on antioxidant and anticancer activities of B. bassiana. The highest contents of total polyphenol (6.51 ± 0.04 ppm) and flavonoid (1.10 ± 0.06 ppm) were detected in the B. bassiana of 15 day medium. The IC50 value of DPPH radical scavenging activity was ranged from 263.4 ± 13.3 to 461.9 ± 23.9 μg?ml?1 SOD activity was ranged from 93.7 ± 16.6 to 99.8 ± 3.8 μg?ml?1. Also ABTS radical activity was ranged from 99.7 ± 1.2 to 156.9 ± 2.9 μg?ml?1 of which the strongest activity was determined of 15 day medium. Especially, 93.7 ± 16.6 μg?ml?1 of 15 day medium showed highest activity by SOD. In cytotoxicity test against three cancer cell lines, HepG2 (liver), MCF-7 (breast) and A549 (lung), showed the highest toxicity with IC50 values of HepG2 (127.8 ± 2.3 μg?ml?1) cell lines of 10 day medium. Also MCF-7 (129.1 ± 6.8 μg?ml?1), A549 (163.8 ± 4.1 μg?ml?1) showed the highest toxicity of 5 day medium. These data suggest Enthomopathogenic of B. bassiana culture medium could be potential candidate for natural antioxidants.
