Anthocyanins are very important constituent of human diet. In recent years, they have gained much attention due to their antioxidative properties. As the radish (Raphanus sativus L) has rich content of anthocyanins, the study is aimed to develop increased functional radish from selected radish varieties. ‘Bordeux’ is a hybrid variety of breeding between one accession derived from ‘Oharu’ as a maternal variety and ‘Chungpihongsim’ as a paternal variety. In this study, we investigated the new varieties of radish commonly consumed in Republic of Korea for their total phenolic content (TPC) and antioxidant activities using three (DDPH, FRAP and CUPRAC) different assays. The selected radish varieties like ‘Bordeux’, ‘Chungbok’, ‘3209’, ‘Chungwoon’, ‘Oharu’, and ‘Chungpihongsim’ were procured from the company Syngenta Korea. Among the selected radish varieties, ‘Bordeux’ (289 μg/g FW) and ‘Chungpihongsim’ (276 μg/g FW) revealed maximum amount of phenolics; whereas ‘3209’ (103 μg/g FW) and ‘Chungwoon’ (166 μg/g FW) showed the lower amount of phenolics content, respectively. Extracts from these studied radishes showed good to moderate antioxidant activities. The varieties ‘Chungpihongsim’ and ‘Bordeux’ revealed maximum antioxidant activity for all assays as demonstrated. However, some varieties like ‘3209’ and ‘Oharu’ exhibited the lowest antioxidant activity in all the tested assays, viz; DPH, FRAP and CUPRAC in μg TE/g FW, respectively. The antioxidant activities may be attributed to the higher phenolic acid contents as a linear relation was observed between the two components and the antioxidant parameters.

Recently, brand equity is paid much attention in various industries. However, container liner shipping companies are still unfamiliar with this concept, and also the brand equity model has not been tested yet in shipping context. This study, therefore, aims to measure the relative importance of brand equity factors of container liner shipping companies by employing AHP (Analytic Hierarchy Process). This study concludes that perceived quality, in particular cost-related service quality, is the most influential factor of brand equity, while weak support is found for brand association. In addition to this, group comparisons were conducted between shipping companies, freight forwarders and academics. The results will be useful as they firstly define brand equity and its role in shipping context, highlighting the significance of brand management to container liner shipping firms. This evaluation is not an end in itself, but will eventually be utilised as a tool to build competitive advantage which cannot be easily imitated by competitors.

The pollen grain is a unique tricellular structure suitable for the delivery of the sperm cells to the ovule. All nutrients required for microspore and pollen cell growth are derived by passage through the anther locule and secretion by the tapetum lining. During later stages the tapetum degenerates but contributes to produce pigments, waxes, lipids and proteins which form the pollen coat and function in signaling between male (pollen) and female (pistil) tissues. The development of both normal pollen and tapetum is necessary for the fertilization processes in rice and would be exploited for the induction of male-sterility which is very useful to improve economic value of crops. We aredeveloping new approaches using a conditional male-sterility for the F1 hybrid seed production in rice. The conventional three parental systems for F1 hybrid seed production requirethe following three lines: male-sterile line, maintainer line, and restorer line. In this system, a critical requirement is to maintain the male-sterile inbred lines. Here we suggest molecular approaches, in which the engineered male-sterile plants are generated by regulating endogenous hormonal balance through the loss-of-function of genes. We can expect the male-sterility can be restored by exogenous applications of hormones such as gibberellin or jasmonic acid. Based on two parental systems, we will address the answer onfollowing question: how can we maintain a male-sterile line producing 100% male-sterile progenies without a maintainer?
