This study conducts an analysis to verify an existence of co-movement among the exchange rates of Yuan-Dollar, Yen-Dollar and Won-Dollar by using time series data. An analysis period is divided into two periods. Therefore the first analysis period is from Dec. 17, 1997 to Jul. 21th. 20, 2005 and the second analysis period is from Jul. 25th, 2005 to Nov. 20th. 2009. This paper uses VAR model and daily data of exchange rates during the period. According to the result of an empirical analysis, yuan-dollar exchange rate has affected by th other variables ; yen-dollar exchange rate. It can be proved by result of an impulse response test and variance decomposition test in the second period. Therefore the won-dollar, yen-dollar, and Yen-dollar exchange rate has been influenced each other and the relationship will be maintained.

게임프로그램 제작이 단순히 3D 또는 온라인게임 등으로 분류하여 엔진과 게임프로그래밍을 하던 시기를 지나 이제는 게임프로그래밍의 종류를 세분화하여 인공지능 게임프로그래머의 역할이 게임을 좀 더 재미있게 할 수 있는 시점이라 하겠다. 본 논문에서는 강화학습 알고리즘을 이용하여 보상 값을 받아 줄고누 보드게임 말이 학습하게 하여 지능적으로 움직이게 하였다. 구현된 게임 말이 지능적으로 잘 움직이는지 확인하기위해, 보드게임을 제작하여 상대방 말과 승부를 하게 하였다. 실험결과 일정횟수 학습한 이후, 임의로 움직이는 말보다 성능이 월등히 향상됨을 알 수 있었다.

보드게임은 많은 수의 말들과 상태공간을 갖고 있다. 그래서 학습이 많은 시간동안 학습을 하여야 한다. 또한 상대방과의 대결이 1 대 1 로 이루어지지 않고, 여러 말 대 여러 말로 이루어지므로 전략적인 사고가 필요하다. 그러므로 최적의 학습을 적용하여야 한다. 본 논문에서는 강화학습 알고리즘을 이용하였다. 보상 값을 받아 보드게임 말이 학습하게 하여 지능적으로 움직이게 하였다. 학습 도중에 동일한 최선 값이 있을 때, 줄고누 문제 영역 지식을 활용한 휴리스틱을 사용해 학습의 속도 향상을 시도하였다. 단순 구현된 말과 개선 구현된 말을 비교하기 위해 보드게임을 제작하였다. 그래서 일방공격형 말과 승부를 하게 하였다. 실험결과 개선 구현된 말의 성능이 학습속도 측면에서 월등히 향상됨을 알 수 있었다.

In order to study the disaster of typhoons which hit the Korean peninsula a period of 22 years from 1959 through 1980 was covered to collect necessary data with respect to attack of typhoons and their damage. Centering around the Korean peninsula, typhoons which attacked between 1959 and 1980 were grouped according to their treking routes and damage for detailed analyses. The results are summarized as follows: 1. The average annual damage of typhoons in the Korean peninsula was found to be 1.27 from June to September. The monthly distributions were found to be 53.6% in August, 28.6% in September and 14.2% in July. 2. About an half (56.4%) of the typhoons which hit the Korean peninsula passed through the western coast and 27.3% through the southern and 14.6% through the eastern. Typhoons of the we8tern coast were divided by their treking routes as 25.5% in CWE type (Jul., Aug., Sep.), 14.6% in WE type (Jul., Aug.), 16.3% in W type (Jul.). 3. The minimum SLP averaged 976.6mb and ordere:l by the treking routes as E$_1$$_1$ and CWE types are higher 20mb than S, E or WE types. 4. The Korean peninsula was damaged by all number of the typhoons in WE or S type, by a third at number of its in E or WE and WI type. 5. The annual probabilities of typhoon-disasters were 0.773 for once or more, 0. 409 for twice or more, and 0.091 for three times or more. Hearvy damage experienced in the Korean peninsula are found to have an annual. 6. Amount of the damage by the treking routes in ordered S>WE>CWE>E>W$_1$, and heavy storms experienced in the Xorean peninsula are found to have accompanied the WE and S types during the months of August and September. 7. The average annual damages were found to be 110 at the death-tall, 45, 000 at the sufferers and 10.5 billion at the property damage. 8. Seventy-sex percent of the all damage in the Korean peninsula distributed on the district from the 36th Parallel south and included Chie Ju island.
