In this study, a total of 51 cases of hydraulic model tests has been conducted for various wave conditions and slope angles of breakwater to develop a stability formula for Rakuna-IV armoring a rubble-mound breakwater. The stability number of the formula is expressed as a function of relative damage, number of waves, structural slope, and surf similarity parameter. The stability formula is derived separately for plunging and surging waves, the greater of which is used. The transitional surf similarity parameter from plunging waves to surging waves is also presented. Lastly, to explain the stability of Rakuna-IV to the engineers who are familiar with the stability coefficient in the Hudson formula, the required weight of Rakuna-IV is calculated for varying significant wave height for typical plunging and surging wave conditions, which is then compared with those of the Hudson formula using several different stability coefficients.

This paper examines the studies and its tendency on Japanese Confucianism Research from 2007 to 2009 in Korea. In recent years, Japanese confucianism studies in Japan, China and Taiwan have been introduced to the academic society of Korea. And many scholars who major in Japanese thought have been invited to Korea and published the results of their research in Korea. Also, there have been researchers who obtained the degrees of Doctor or Master by researching Japanese thought. This paper, lastly, introduced the papers on the Japanese confucianism which were published in Korea during the recent 3 years. If we evaluate all the trend in researching Japanese confucianism in Korea, it can be said that it is still in the early stages. Recently, however a small but significant advance has been acquired. In conclusion, we can expect the future of the Japanese confucianism studies in Korea.

This report introduces the papers on Japanese Confucianism and Kokugaku thought written in Japanese, Korean, Chinese language and English during 2008. In this paper the data is based on the periodicals index databases of the digital libraries such as the National Diet Library of Japan, the China Academic Journal of China, the National Central Library of Taiwan and the National Assembly Library of Korea and so on. There were 42 articles published on the Japanese Confucian School. In the articles, 29 ones were written in Japanese, 7 in Korean, 4 in Chinese, and 2 in English. 54 articles were published on Yangming School, 41 written in Japanese, 2 in Korean, 10 in Chinese, 1 in English. 50 ones also published on Kohaku School or Mitogaku School. In the articles there were 32 ones written in Japanese, 7 in Korean, 9 in Chinese, 2 in English. And 58 ones on Kokugaku School were published, 51 were written in Japanese, 4 in Korean, 1 in Chinese, 2 in English. Totally 204 articles were written in Japanese, Korean, Chinese, or English language in 2008 throughout the world. This report is divided into 4 chapters, such as Chapter 1 - Syusigaku School, Chapter 2 - Youmeigaku school, Chapter 3 - Kohaku School and Mitogaku School and Chapter 4 - Kokugaku School. In each chapter, some articles are briefly introduced and some are in detail.
