This study investigates the aspects of vocabularies used in Korean textbooks in Japan(JP) from corpus-based perspectives and suggests ideas for future directions in developing textbooks. To attain this goal, this study compares JP with 4 reference corpora(spoken, soft opera and textbooks in Korea[KR]), regarding to token & type frequence, lexical richness, and coverage of Korean fundamental vocabulary list. The results show that a) JP’s token frequency is 1.3 times as large as KR, but the type vice versa; b) JP``s lexical richness is richer than that of KR; and c) the frequence distribution of the part of speech in JP is the order of noun-verb- adjective-adverb, which is the same with KR, but different from other corpora, especially in terms of adverb, pronoun and interjection; d) concerning the coverage of fundamental vocabulary, JP covered 59.4% of the list; e) the over-represented words are noun(63.5%), and these have tendency to be related to the specific semantic fields. From these results, I suggest that textbook developers are better to refer to frequency information in a natural language, instead of relying on their intuition only.

Dye to recent development such as increasing price of fossil fuels and energy offers such a solution. Wave energy supplies. Weve energy offers such a solution. Wave energy is the most consistent of all the intermittent renewable energy sources. In addition to this, very large energy fluxes occur in the ocean waves and by using appropriate wave energy converters the energy can be harnessed. The present study looks at utilizing a direct drive turbine of cross flow type to extract energy from ocean waves indirectly. This novel design incorporates a turbine in an enclosed in a closed tank. utilizing the energy generated from sloshing.
