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.

Game program manufacture had been classed by 3D or on-line game etc. simply. But, atomized game programmer's kind now. So, Artificial Intelligence game programmer's role is important. This paper used reinforcement learning algorithm for Jul_Gonu board characters to learn, and so they can move intelligently. To compare a learned character to an random one, a board game was created, and then they fought against each other. As a result, learned character‘s ability was far more improved.

Objective : This study was aimed to report a patient accompanied by alcoholic derogation acute abdominal pain treated with oriental medicine combined with conventional treatment. Methods : A 36 year old female patient complained of acute abdominal pain for one year from Apr. 2009. She had treated at local general hospital. But the symptom was not reduced. Instead, it was aggravated on Jul. 2010. The main symptoms were left flank pain, chest discomfort, nausea and anorexia. The patient was treated by oriental medicine (herbal medicine (Chunggan-plus), acupuncture, moxibustion, etc) combined with conventional medicine from Jul. 10th, 2010 to Jul. 17th, 2010. We observed the patient with evaluation of laboratory test and imaging scan. Results : Most of the symptoms of the patient were improved. Especially, the abdominal pain were disappeared from grade 3 to grade 0. No side effects were noted during treatment. Conclusion : This results suggest that the oriental medicine combined with western medicine may effective to treat alcoholic derogation acute abdominal pain.

It takes quite amount of time to study a board game because there are many game characters and different stages are exist for board games. Also, the opponent is not just a single character that means it is not one on one game, but group vs. group. That is why strategy is needed, and therefore applying optimum learning is a must. This paper used reinforcement learning algorithm for board characters to learn, and so they can move intelligently. If there were equal result that both are considered to be best ones during the course of learning stage, Heuristic which utilizes learning of problem area of Jul-Gonu was used to improve the speed of learning. To compare a normal character to an improved one, a board game was created, and then they fought against each other. As a result, improved character's ability was far more improved on learning speed.

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.
