This investigation was carried out to research on the actual states for bycatch and discards of catches caught by funnel net from December, 2007 to June, 2010. Fishing grounds were Manheung-dong and Ocheon-dong in the coastal waters of Yeosu. The number of the investigation was 21 in Manheung-dong and 7 in Ocheon-dong fishing ground. In Manheung-dong, the species of catches were 26 of fish, 6 of cephalopod and 5 of crustacean. In Ocheon-dong, the species of catches were 25 of fish, 6 of cephalopod and 4 of crustacean. In the two all fishing grounds, the largest amount of species was revealed as gray mullet. Among these catches, the number of non marketable species that were classified and discarded ones, were 9 in Manheung-dong and 7 in Ocheon-dong. Also, among the marketable species which were small entity or too tiny catches to commercialize and not fresh ones were discarded. The proportion that they dominate in the whole catches was 37.1% in the number of catches and 5.4% in the weight of catches in Manheung-dong, and 6.9% in the number of catches and 0.3% in the weight of catches in Ocheon-dong. In case of Manheung-dong, the monthly discarding proportion was the highest with 59.4% in the number of catches in may and 17.6% in the weight of catches in November, and in case of Ocheon-dong, the both of them were the highest in February, with 28.0% in the number of catches and 5.1% in the weight of catches.

Volatile organic compounds in the ambient air were gathered irregularly by normal temperature concentrating method at Odea-ri and Oceon-ri Ulsan-gun in the neighbourhood of Ulsan Petrochemical Industrial Complex and analyzed with gas chromatograph. Several hydrocarbons in common aklospheric air or emitted fugitively from the chemical plants were identified and quantified by comparison with the retention times of standard compounds. The results from several field surveys in 1992 show that the concentrations of styrene at residential area of Odea-ri and Ocheon-ri were less than 0.4 ppm, but once a while greater within the chemical plants area. When it smelled unpleasantly in these area, the concentration of hydrocarbons were also high. It was concluded that the close and long-term investigation about other odorous components but hydrocarbons will be necessary to ascertain the cause of unpleasant odor of these area.

I in this article analyzed poetry and prose written by Ming Navy forces who visited Chungcheong Navy Castle(忠淸水營) in Ocheon(鰲川) during Japanese Invasion of Korea in 1592(壬辰倭亂) and the remains concerning them. Chungcheong Navy Castle was used as a way station when Ming Navy forces came and went to the Southern Sea during Japanese Invasion of Korea in 1592. In April 1598, "Gyegong cheongdeok bi(季公淸德碑)" was erected to praise Gyegeum for his virtue. The villiagers have served "Gyegeum cheongdeok bi" as a god for the peaceful sea and good luck from the ancient times. Zhang Liangxiang(張良相) & Jia Xiang(賈祥) developed his great spirit to appreciate beautiful viewwhen he defeated Japanese force and ascended again to Yeongbo Pavilion(永保亭).

이 연구는 충남 보령 정전 및 오천 지역 석면 광상의 성인적 차이에 대해서 이다. 두 광산은 지난 수십년 동안 석면 광산으로 개발이 되었던 곳이다. 정전광산의 모암은 사문암이고 오천광산의 모암은 백운암이다. 석면 시료 및 모암시료가 야외 조사에서 채취 되었고, 석면의 종류 및 원소 함량을 알아보기 위해 광학 현미경 및 주사전자 현미경으로 관찰되었고, X-선 회절분석기, 에너지 분산 분광장치를 이용하여 분석 되었다. 석면들은 열수의 유입통로로 추정되는 층리, 균열, 열극을 따라 발견이 되나, 둘 사이에서는 두드러진 특성 차이를 보인다. 정전의 사문암은 백석면, 투각섬석 석면, 양기석 석면을 포함한다. 비석면형의 투각섬석과 양기석도 발견이 된다. 백석면은 맥에서 교차 섬유, 미끌림섬유로서 산출되고, 수 mm에서 cm의 두께의 균열에서 산출된다. 투각섬석과 양기석 석면은 수 cm에서 수 십 cm 두께의 균열 및 열극을 따라 발견이 된다. 이는 정전지역의 석면이 사문암과 열수의 반응에 의해 형성되었음을 암시한다. 오천 지역의 백운암은 투각섬석 및 양기석 석면을 포함한다. 이 석면들은 층리, 균열, 열극에서 산출된다. 이는 오천 지역의 석면이 백운암과 열수의 상호 작용에 의해 형성 되었음을 암시한다. 위의 결과 들은 같은 행정 구역인 보령 지역에서도 두 다른 모암을 갖는 석면 광산이 위치함을 보여 주고 있다. 이들은 성인의 차이를 반영하여 석면광물에서도 차이를 보인다.

한반도 동남부에서 가장 규모가 큰 마이오세 포항분지의 남서부를 대상으로 상세한 지질도 작성과 지질구조를 분석하여 분지 발달사를 해석하였다. 포항분지 남서부는 북북동 방향의 분지 내 지구내지루에 의해 기하와 변형사가 서로 다른 서쪽의 보문구역과 동쪽의 오천구역으로 나누어진다. 보문구역은 포항분지 초기 확장 이후 거의 변형되지 않은 반면, 오천구역은 충전물의 퇴적 이후에도 후기 변형이 지속·중첩된 지역이다. 따라서 보문구역은 포항분지 최초 확장 형식에 대한 중요한 정보를 제공한다. 보문구역은 북북동 방향의 정단층들과 북북서(북서) 방향의 우수향 주향이동단층 분절들이 지그재그로 이어진 서편 경계단층에 의해 침강이 주도되었으며, 이 경계단층은 남쪽으로 한반도 동남부 마이오세 지각변형의 서쪽 한계선이며 우수향 주향이동성 주변위대로 알려진 연일구조선과 연결된다. 따라서 포항분지는 17-16.5 Ma 경 활동을 시작한 연일구조선 북쪽 말단에 우향스텝 형태로 생성된 북북동 방향의 정단층 또는 사교이동단층에 의해 서북서-동남동 방향으로 확장된 횡인장단층말단분지로 최초 침강된 것으로 해석된다. 이로 인해 보문구역에는 서쪽으로 갈수록 분지의 깊이가 더 깊어지는 북북동 방향의 비대칭 지구 또는 반지구가 생성되었다. 이후 포항분지의 확장과 변형은 오천구역을 포함하는 보다 동편 지역으로 이동하였다.

The study on the government office building in Chungcheong Suyeong(忠淸水營) is very rare. How were the Gaeksa(客舍) and Dongheon(東軒) which are representative government office buildings in Suyeong, maintained and what was the aspect of it, while passing through the upheaval period of the end of Joseon(朝鮮)? And where was the original place and was there any change in use? It is so regrettable that these subjects were not figured out yet. So I thought it is very important task to figure out its actual aspect by investigating the maintain state of the Gaeksa and Dongheon and the change of their places. So this study examined the related historical records and, based on it, analyzed "Ocheon GoonJi(鰲川郡誌)" in various view points. Through this analysis, this study could figured out the maintain aspect of the gaeksa and dongheon and the change of their places, and be able to deduce the other change of the government office building. This study could assume the places of each government office buildings by comparing this investigated result and the analyzed result of the original cadastral map in various view points. As the result of the study done by this method, this study confirmed the maintain state of the Gaeksa and Dongheon in Chungcheong Suyeong while passing through the upheaval period of the end of Joseon. And this study figured out the places of the Gaeksa and Dongheon, and be able to confirm their places by the lot number on the original cadastral map. Along with this, this study could estimate Jo(趙) family's confliction with the residents at that time by verifying the lot numbers of the Sapaeji(賜牌地) which this family received from the government. And among the names of the government office buildings, for the Jangkyocheong(將校廳) which is in dispute because of the name, this study figured out that the author of "Ocheon GoonJi" made a mistake in writing Dongheon.

The purpose of this study is to examine the condition of the architectural location and the history of Yeongbojeong and investigate the motivation which formed the YuSik space and the poetical circles of it. And another purpose of the study is to discover how Yeongbojeong, located in a military camp in Western coast, displayed the poetic scenery so to be the poetic summer house among so many Nujeongs in Joseon. Yeongbojeong is currently located in Soseong-ri, Ocheon-myeon, Boryeong City, Chungnam. Yeongbojeong has the biggest size among all the summer houses in the country with 24 architectural rooms. And Yeongbojeong is not only the summer house in which people could simply see its scenery, but beyond the poetic space of Joseon, it was the unique poetic summer house which enables poets and calligraphers to enjoy imaginary freedom. The time range of the study was from the building of Yeongbojeong in 1504 to its demolish in 1901, and its space range was taken focused on the particular scenery which was seen from around Yeongbojeong. To investigate the architectural aspect of Yeongbojeong, the existing records about the summer houses, "OcheonGoonJi" and the landscape paintings etc. were referred. The travel records and poems in the work collection of the famous poets who explored Yeongbojeong were referred to examine the formation of the Yeongbojeong poetical circles. The result of the study shows the process that Yeongbojeong had become the famous national place with scenery and how it became the most visited YuSik space. And this study figured out the full account of Yeongbojeong poetical circles which had been formed by so many poets of the country for 4 hundred years.

Yeongbojeong was a famous pavilion of Joseon, which was located in Chungcheong-Suyeong, Ocheon-myeon, Boryeong-si. It was an open place for poets and calligraphers to freely visit during 400 years. Until today, it is widely said that Yeongbojeong was newly built by LeeRyang in 1504, who was Sugunjeoldosa(naval forces officer). The researcher investigated Gyujanggak to search Lee Maenghyu's "Asulrok-Book", and it was determined that Yeongbojeong was created by Gang Soon, 36 years earlier than LeeRyang. Accordingly, this research aimed at determining the appropriateness of the creation of Yeongbojeong. "Asulrok-Book", which said, "Yeongbojeong was Wonjeong(園亭) of Gang Soon during Yejong's reign", however this research could settle imperfection of Geungeo Gimun which was not clearly explained. Yeongbojeong was created due to Gang Soon's Wonjeong in 1468, however he was also a traitor and was executed, so that nobody wanted to mention about it. Therefore, it was determined that no phrase related to the record of creation of Yeongbojeong by Gang Soon out of lots of Yongbojeong Jeyoungsi and Gimun. Lee Maenghyu was a brave scholar who recorded 'Yeongbojeong was Gang Soon's Wonjeong' confidently, breaking such taboo. This research intended to clearly investigate the year of foundation of Yeongbojeong and establish the history of Chungcheong-Suyeong by thoroughly analyzing newly discovered "Asulrok-Book", existing "Ocheong GoonJi", and "Chungcheongsaryejib" and considering the fact relevance. As the result of this research, it was determined that Yeongbojeong was Gang Soon's Wonjeong through "Asulrok-Book". The point that Yeongbojeong was forfeited reverted to neighboring Chungcheong-Suyeong after Gang Soon was executed due to his participation in a conspiracy also was a newly discovered fact. LeeRyang, Sugunjeoldosa, can be said a brave commander, since he put up the original Yeongbojeong instead of abandoning the name Yeongbojeong of Gang soon. So far, Yeongbojeong is widely accepted as 'new construction of Yeongbojeong by LeeRyang in 1504'. However, since the record of Gang Soon's Wonjeong was discovered, and as the result of diversified analysis and examination, it is proper to correct the foundation year of Yeongbojeong as 1468.
