This study has performed to investigate the Buddhist remains in Korea Particularly, the Nirvana and Sarira Pagoda at Tongdo temple, Sangwoun temple, Jungam temple, Bubheung temple and Bongjongam are handled by using on the observation, references and interviews with some experts in Buddhist culture. The results in Korea are compared with that of Thailand and China. But, The Nirvana and the Sarira Pagoda to keep Buddha's relic are quite different at each temple in Korea, Thailand and China. The air velocities were calculated in side of the Nirvana by using STAR-CD.

우리나라 연안 해역의 공동어장과 패류양식장에 서식하는 굴, 가리비, 반지락등 유용 조개류를 무차별 포식하는 불가사리는 패류양식 어민에게는 해적생물이라 불리우져, 이들을 퇴치하기 위한 대대적이고 적극적인 포획작업이 이루어지고 있다. 제주도의 경우도 마을 어장의 주요수산물인 전복, 소라, 오분자기등의 자원보존을 위한 불가사리 제거작업을 실시함과 동시에, 자원조성을 위한 종패 살포를 지속적으로 실시하고 있다. (중략)

The flower type ornament of the gilt bronze palace-type sarira reliquary among those sarira reliquaries of the East Pagoda at the Gameunssa Temple Site, which is the Treasure No. 1359 owned by the National Museum of Korea, was separated from the sarira reliquary in November 2010, thus conducting conservation treatments to be done on two items including the gilt bronze palace-type sarira reliquary during the period of March-October 2011. Those conservation treatments were carried out by following the process of removing the coated areas having excessive gross and bubbles, re-coating with Incralac, and then strengthening both the cracked areas and the separated flower-type ornaments with woven glass fiber after rejoining. For those areas where removal of gloss and bubbles at the coating and adhesive areas was not possible, the gloss and bubbles were made less perceivable through matting treatment and coloring.

A study on the enhancement of the dewaterability of sewage sludge was carried out by using the sea waste materials as a dewatering aid. It was made from a starfish and a shell by heating at $105∼700 ^{\circ}C$ and centrifuge and belt press were used as a mechanical dewatering process. The moisture content of sludge cake was reduced by 15∼22% (w/w) after addition of the dewatering aid at the dose of 1∼8 g/100mL of digested sludge. CST (capillary suction time) was measured to evaluate the effect of dewatering aid on sludge dewatering properties. CST was reduced after addition of a shell while increased after addition of a starfish. Enhancement of dewaterability after addition of a shell was better than that of a starfish. The heating temperature effect of the dewatering aid on dewaterability was not clear.

This study is going to suggest the technology to recognize a starfish by judging various starfish images. In case of recognition of single objects of the asterias amurensis, a starfish can be judged by using concave features and short line features but in case of multiple objects, it is impossible to extract the features of a starfish using concave features or short line so that it can't be recognized as a starfish. Accordingly, it is going to suggest the recognition technology using the features such as numbers of standard deviation, relative degree standard deviation and valid deviation of a long line by using the region central moment and a long line of multiple objects. As a result of experiments of the suggested technology, there were cases that recognition failed because the conditions of the standard deviation of a long line or the numbers of valid deviation of the relative degree couldn't satisfy the conditions but around 95% of a high recognition rate was shown.

The population of highly prolific, predatory Asterias amurensis is growing sharply from year to year along the coastline of Korea, a nation surrounded by water on three sides. To make matters worse, the fact that Asterias amurensis devours living fish and shellfish has caused a heavy loss for fishermen involved in the aquaculture industry. What it all boils down to is the significance of technologies allowing one to recognize Asterias amurensis individuals using underwater images for the purpose of exterminating Asterias amurensis or identifying a change in the population of Asterias amurensis or the migration route of Asterias amurensis. An improved Asterias amurensis recognition method based on the morphological characteristics of Asterias amurensis was proposed in this paper. The proposed recognition method aimed at cases marked by the lack of extraction information on concaveness and convexity, which are the morphological characteristics of Asterias amurensis. Extracting all the characteristics of Asterias amurensis from images taken underwater is very difficult. In this respect, the proposed recognition is effective in terms of recognizing individuals in a diversity of Asterias amurensis images. As a result of the experiment, Our proposed method has achieved superior performance with 92.5% than other method.
