In a game called red and black, you can stake any amount s in your possession. Suppose your goal is 1 and your current fortune is ｆ, with 0 < f < 1. You win back your stake and as much more with probability p and lose your stake with probability, q = 1- p. Ahn(2000) considered optimum strategy for this game with the value of p less than $\frac{1}{2}$ where the house has the advantage over the player. The optimum strategy at any f when p < $\frac{1}{2}$ is to play boldly, which is to bet as much as you can. In this paper we perform the simulation study to show that the Bold strategy is optimum.

Recently, every student would take lessons without knowing no lecture in campus life. And, If you are a university student, you tired a course to register in a crowded. For solving this problem, we choose the cellular phone. Nowadays peoples have one cellular phone to one person in korea. Using cellular phone, you can use cellular phone anywhere any time. In this paper, we studied mobile synthesis system using mobile cellular phone. According to use mobile campus system, the university and students can use easy an one to one service in ubiquitous.

It is a quite quality concerning to control temperature of single crystalline growth as it does when you get most of heat treating products. It is also important factor to control temperature when you make the $Al_2O_3$(single crystalline) used to artificial jewels, glass of watches, heat resistant transparent glasses. Thus, it is a major interest to get the proper temperature in accordance with the time process while you are making mixture of oxygen and hydrogen to have the right temperature. In this paper, we will study of electrical valve positioning system for the gas mixture to improve the quality of products.

In a game called red and black, you can stake any amount is in your possession. Suppose your goal is 1 and your current fortune is $f$, with 0$p$ and lose your stake with probability, $q$=1-$p$. In this paper, we consider optimum strategies for this game with the value of $p$ less than $^1/_2$ where the house has the advantage over the player, and with the value of $p$ greater than $^1/_2$ where the player has the advantage over the house. The optimum strategy at any $f$ when $p$<$^1/_2$ is to play boldly, which is to bet as much as you can. The optimum strategy when $p$>$^1/_2$ is to bet $f\cdot\alpha$with $\alpha$, a sufficiently small number between 0 and 1.

This paper aims to give beginners an introductory course on how to write a medical paper more effectively. Bear in mind the reviewer and the reader will be reading your paper for the first time, so you should write it easily. Everything in your paper must be coherent. Use of the active voice is usually shorter and clearer. Organize your story carefully and logically, and then you can avoid unnecessary repetition in different sections. Think hard, because research is made by the mind, not by the hands. Write technically and powerfully. Above all, you have to meet the submission regulation of the target journal exactly.

We Professional Engineers in Japan and Korea have decided to introduce the theme of 2003's convention after two bilateral talks. So we will discuss on the near future in the Northeast Asia. I will make a speech based on this concept. I am very glad to talk to everybody here. I have been participating in this congress, since 1985 and I have made friends with Korean PE s. I hope that I attend the congress until may age of 84 when the 50th congress would be held. The speech is based on my experience and I will speak frankly So, I was born In Seoul and brought up in Pusan on my childhood but I only understand "Hello everybody" "Thank you" "How much" "No problem" "I love you" in your own language. Fortunately Mr Chung Byung Sook helps me to make myself understood in Korean as a translator. Thank you.

In discrete red and black, you can stake any amount s in your possession, but the value of s takes positive integer value. Suppose your goal is N and your current fortune is ${\Large\;f},\;with\;O<{\Large\;f}. You win back your stake and as much more with probability p and lose your stake with probability, q=1-p. In this study, we consider optimum strategies for this game with the value of p less than ${\frac{1}{2}}$ where the house has the advantage over the player. It is shown that the optimum strategy at any ${\Large\;f}$ is the DBold strategy which is to play boldly in discrete red and black when $p<{\frac{1}{2}}$. And then, we perform the simulation study to show that this strategy, which is to bet as much as you can, is optimal in discrete case.

The purpose of this study is to analyze the structural relationship among expectation value(relational, hedonistic), brand image, brand attitude, continuance viewing intention. The survey subjects to achieve the purpose of this study were selected the 521 YouTube sports contents Viewer in the metropolitan area. Data processing was done with SPSS 23 for frequency analysis, Cronbach's α analysis. Also, AMOS 21 was used for confirmatory factor analysis and structural equation model analysis. The results of the analysis are as follows: First, both relational value and,, hedonistic value had a positive effect on the brand image. Second, both relational value and,, hedonistic value had a positive effect on the brand attitude. Third, both brand image and brand attitudee had a positive effect on the brand attitude.
