This study aimed to investigate the effect of visual input enhancement (VIE) on the comprehension of reading texts and the learning of two grammatical forms: English relative clauses and articles. Individual learners’ working memory (WM) capacity was also tested to explore its impact on the effectiveness of VIE. A total of 48 Korean college learners of English were assigned into three groups: (a) relative group receiving VIE on relative clauses (b) article group receiving VIE on articles, and (c) a control group receiving no VIE. Results showed that VIE did not have any negative effect on the learners’ reading comprehension. Rather, it had positive effects on the learning of the two grammatical forms. According to the findings, VIE on relative clauses enhanced the learners’ receptive knowledge of the grammatical form, whereas VIE on articles enhanced the learners’ productive knowledge of the form. There was a potential link between the effectiveness of VIE and the learners’ working memory processing ability. Pedagogical implications are also discussed based on these findings.

“Jecy Gold” is a new kiwifruit variety developed at the National Institute of Subtropical Agriculture (NISA), RDA in 2003, which was for the utilization as fruit with yellow flesh and high soluble solids. This variety was selected from seeds obtained from the cross breeding between Actinidia chinensis cv. “Golden Yellow” and A. chinensis cv. “Songongu” with yellow flesh in 1997. Seedling and line selections were conducted from 1998 to 1999, and characteristic trials were carried out from 2000 to 2002. After developed, it was also conducted to the test of adaptability in kiwifruit orchards of Jeju island from 2003 to 2006. The branch of “Jecy Gold” sprouts strongly and the color of leaf is slightly dark green. The shape of fruit is obovoid, and the color of peel is yellowish-brown without hair. The average weight of fruit is 128.4 g. The core is middle and soft, the percicarp is golden yellow, and the texture is fragile and juicy. Soluble solids concentration is 14.8 oBrix. The total acid content is 0.69% and the fruit yield is higher about 30% than that of A. deliciosa cv. “Hayward”. The content of vitamin C is higher than that of A. deliciosa cv. “Hayward”. The harvesting time is from late October to early November and the fruit can be preserved about 90 days at 2°C. This variety can be planted bellow 100 m sea level and should be grown under shelter to prevent from disease and cold. This variety will be cultivated about 100 ha by 2011 in the southern part of Korea and has been supplied about 10 ha in 2007.
