In this paper I propose the semantics of two modality markers in Korean, keyss and (u)1 kes. I compare the two modality markers with respect to some properties. First, keyss is used to express logical necessity while (u)1 kes can be used to express a simple prediction as well. Second, keyss expresses some logical conclusion from the speaker's own information state without claiming it is true. On the other hand, (u)1 kes expresses the claim that the speaker's prediction will be true. Third, the prediction of keyss is non-monotonic: it can be reversed without being inconsistent. However, that of (u)1 kes cannot. Fourth, (u)1 kes can be used freely in epistemic conditionals, but keyss cannot. Finally, when keyss is used, the prediction cannot be repeated. The prediction from the use of (u)1 kes can be repeated. To account for these differences, I propose that keyss is used when the speaker makes a purely logical presumption based on his/her own information state, and that (u)1 kes is used to make a prediction which is asserted to be true. This proposal accounts for all the differences of the two modality markers.

Pyomindaehwa is a study book written in Korean and it takes a form of an investigation document made up of a conversation between Chosen's castaways and an interpreter taking place in Naesirogawa and Satsuma on the south end of Kyushu, Japan in the 19th century. This book is in three volumes. Many terminologies such as timber parts, sail, rigging and equipment have been shown in the last volume, which is mainly about a repairing process of drifting ship. Especially, timber parts' terminologies including hull's term were schematized in Kumamoto Text(1854b). This study have attempted to find out Naval architectural clues helping estimate actual drifting ship's type and bulk on the evidence of the contents. Based on the studies, it is possible to presume the type of Korean boats and ships, which are similar with the ones from database of 21 traditional fishing boats in the report on Investigation of Korean fishing boats studied previously. This paper has shown the logical process of presumption of types of boats.

창의성을 향상시키기 위해서는 기계적인 계산에 의해서 한 가지 답을 구하는 문제보다는 탐구하고, 추측하고, 논리적으로 추론하고, 다양한 문제해결 전략과 답을 찾아낼 수 있는 문제가 필요하다. 또, 이러한 문제가 학생들에게 활동을 통해 다양한 경험을 제공할 수 있다면 더욱 효과적일 것이다. 이를 위해서는 다양한 학습자료 및 도구, 즉 교수매체의 활용이 요구된다. 본 연구에서는 구체적 활동을 통해서 영재학생의 창의성을 향상시킬 수 있는 교수매체에 대해 알아보고자 한다.
