In this study, the faunae before and after creating the Solbangjuk Wetland Ecological Park located in Jecheon-city were compared. As a result, the change of the fauna according to the creation of the park showed the phenomenon that the species having the strong wilderness are reduced and the rate of general species become higher. In addition, the species which receive the restrictions for moving such as mammals, amphibians and reptiles are being gradually decreased by the increased visitors owing to the creation of the park. Moreover because there was the case where group of fishes have died caused by discharging and working the water in the reservoir during the creation process of the park, the supplementation work for this is required. However, it showed that the insects sucking the honey from flowers in the composed flower garden after creating the park, and the aquatic insects which live in this park that the stable water system for the growth of wetland plants is maintained, are increased, respectively. As a result of this survey, because the reservoir for agriculture adjacent to the residential area is generally small, the securing of the habitat space for the wild animals living in this park when creating the ecological parks seems to be necessary. The countermeasure should be considered so that some areas of the reservoir can be maintained in their natural state by adjusting the visitors' trails and the position of facilities for in order to secure the habitat of the wild animals. 본 연구는 제천시에 위치한 솔방죽 습지생태공원의 조성 전과 후의 동물상을 비교하였다. 그 결과, 생태공원 조성에 따른 동물상의 변화는 야생성이 강한 종들이 감소하고, 일반종의 비율이 높아지는 것으로 나타났다. 또한 포유류, 양서 파충류와 같이 이동에 제약이 있는 종들은 생태공원 조성으로 늘어난 탐방객들에 의해서 점차 감소하고 있다. 그리고 어류는 공원 조성과정에서 저수지 물을 방류하고 작업하여 집단 폐사하는 사례가 있어 이에 대한 보완 작업이 필요하다. 곤충은 공원 조성 후에 조성된 화단의 꽃에서 꿀을 먹는 곤충과 습지 식물의 생육을 위하여 안정된 수계를 유지하고 있어, 이곳에서 서식하는 수서 곤충은 늘어난 것으로 나타났다. 이번 조사 결과, 주거지역과 인접한 농업용 저수지는 크기가 작은 경우가 많아 생태공원 조성시 이곳에서 생활하는 야생동물들에 대한 서식 공간 확보가 필요한 것으로 보인다. 또한 야생동물 서식처를 위하여 방문객들의 탐방로와 시설물 위치를 조정하여 저수지 일부 지역이 자연 상태로 유지할 수 있도록 하는 것이 고려되어야 한다.

Mass mortalities of cultivated organisms have occurred frequently in Korean coastal waters causing enormous losses to cultivating industry. The preventive measures require continuous observation of farm environment and real-time provision of data. However, line hanging aquaculture farm are generally located far from monitoring buoys and has limitations on installation of heavy equipments, Substituting battery pack for solar panels and miniaturizing size of buoy, newly developed system can be attached to long line hanging aquaculture farm. This system could deliver measured data to users in real-time and contribute to damage mitigation and prevention from mass mortalities as well as finding their causes. The system was installed off Gijang and Yeongdeck in Korea, measuring and transmitting seawater temperature at the sea surface every 30 minutes. Short term variation of seawater temperature, less than one day, in Gijang from June to July 2009 corresponded tidal period of about 12 hours and long term variation seemed to be caused by cold water southeast coast of Korea, particularly northeast of Gijang. Seawater temperature differences between Gijang station and the other station that is about 500 m away from Gijang station were 1 ℃ on average. This fact indicates that it is need to be pay attention to use substitute data even if it is close to the station. Daily range of seawater temperature, one of crucial information to aquaculture, can be obtained from this system because temperature were measured every 30 minutes. Averages of daily range of temperature off Gijang and Yeongdeok during each observation periods were about 2.9 ℃ and 4.7 ℃ respectively. Dominant period of seawater temperature variation off Yeongdeok was one day with the lowest peak at 5 a.m. and the highest one at 5 p.m. generally, resulting from solar radiation.

The subject of this study is development of wave height algorithm and sensor. Principle of wave height algorithm was written and made with vertical acceleration measurement by means of an accelerometer placed on a Tilt Assembly System. The field-test of two times for data analysis of wave height sensor was lasted for 8 days with Development Sensor Buoy, Waverider Buoy(Waverider-SG) and Wave Radar(SM-050) in the east costal area. In data analysis of Development Sensor Buoy and Waverider Buoy, the implications of the results were a difference not exceeding 20㎝.
