여름이 찾아오면 많은 사람들이 피서를 즐기기 위해서 해수욕장, 워터파크, 계곡으로 향한다. 하지만 인파가 많은 해수욕장, 워터파크는 쉽게 정보를 찾아볼 수 있지만 소규모인 계곡은 정보를 상대적으로 쉽게 찾기 힘들다. 또한 사람이 많이 붐비는 해수욕장, 워터파크 보다는 좀 더 여유로운 피서를 위해 계곡을 더 선호하는 사람이 늘고 있다. 이를 해결하기 위해 부산, 울산, 경남지역의 계곡을 Google map API를 활용하여 한 번에 찾아볼 수 있고 정보를 제공받을 수 있는 애플리케이션을 개발하였다. 검색기능을 사용하여 Google map에서뿐만 아니라 별도로 원하는 계곡도 찾을 수 있는 기능을 제공한다. 또한 웹사이트와 연동하여 사람들 간에 실제로 계곡을 이용한 후기들을 공유할 수 있는 기능을 제공한다.

The goal of this study was to isolate and characterize the wild yeast strains in the soils of Hajodae and Gyungpodae Beaches, Gyungpo Lake in Kangwon-do, Korea and evaluate their anti-demential and tyrosinase inhibitory activities. Among the 27 yeast strains isolated from 30 soil samples from Hajodae Beach, Cyberlindnera culbertsonii HJ31-1, Dothichiza pithyophila HJ22-4, Metschnikowia bicuspidata HJ16-1, and Sakaguchia cladiensis HJ14-1 were recorded for the first time in Korea. Additionally, six of the 55 wild yeast strains isolated from 45 soil samples from Gyungpodae Beach and Gyungpo Lake had not previously been detected in Korea, such as Aureobasidium melanogenum JR3-1. The microbiological characteristics and anti-demential and tyrosinase inhibitory activities of these previously unrecorded yeasts were investigated. Almost all of them were oval-shaped and had ascospores except for Dothichiza pithyophila HJ22-4, Diutina siamensis JR37-5, and Canadida gelsemii DC 35-1. Furthermore, they were all sugar-tolerant and able to grow in 20% glucose-containing YPD broth, except for Cyberlindnera culbertsonii HJ31-1. Diutina siamensis JR37-5 had the highest tyrosinase inhibitory activity (30.9%).

After Typhoon Chaba (No.18, 2016) collided with Manseongri Beach, a coastal improvement project was carried out since strong external forces such as waves, storm surges and wave-induced currents were observed to cause beach deformation. The shoreline, beach area and beach volume were periodically surveyed. On the basis of this field data, the beach deformation that occurred at Manseongri Beach has been formally described. Over three months after beach nourishment work began, the beaches were gradually stabilized in terms of natural external forces. However, this stabilization was interrupted by Typhoon Chaba. After two months of typhoon weather, the beach returned to a stable state and no changes were observed until one year after the beach recovery work. Just after the typhoon hit, the shoreline receded from the northern side, where no reduction of external forces occurred, while the rear beach area submerged by breakwater advanced. Also, the beach volume decreased by $3,395m^3$ after the typhoon, due to erosion that occurred on the northern beach, with deposition taking place on the southern backshore area. Therefore, it has been concluded that the coastal improvement project undertaken at Manseongri Beach has significantly contributed to conservation in areas of wave-dominant sediment transport.

In this study, the spectrum due to radioactivity contained sand samples from famous beaches in the Yeongnam region was measured. The sand samples were from eight famous beaches in Yeongnam region and were placed into a high-purity germanium detector (HPGe) using with an electric field, which is a semiconductor detector and subjected to a precision analysis of the gamma-rays emitted from the radionuclides in the sand by using a multichannel analyzer (MCA). To measure the concentration of the radionuclides, we obtained a spectrum by analyzing the gamma-rays emitted from the radionuclides for a measurement time of 8,000 seconds. As a result of analyzing the spectrum table, Tl-208 had the highest radioactivity at all eight beaches: A, B, C, D, E, F, G, and H. In conclusion, radionuclides detected in sand samples from beaches in the Yeongnam region are natural radionuclides, but they can affect the inside of the human body. Therefore, there is a need for continuous investigation.

One of the important features of a beach face is the dynamic response to the ever-changing waves and tides imposed from the body of water. Furthermore, human activities at or near the beach can enforce the characteristic changes on tidal motions and wave

2010년 여름철 만리포의 수질은 COD가 지속적으로 2.0 mg/l 이하로 측정되어 양호한 상태였고 SS(부유물질)의 량이 7월 조사에서 30mg/l를 초과하였으나 해수욕에는 무리가 없었을 것으로 판단된다. 식물플랑크톤은 대발생이나 적조 등의 현상이 나타나지 않았다. 대천의 수질은 8월 조사에서 COD값이 평균 2.0mg/l를 초과하기도 하였으나 하절기 정반적으로는 2.0mg/l 이하로 나타나 역시 해수욕장 수질로서는 양호하다. 식물플랑크톤 역시 규조류가 우점하는 보편적인 해수의 특징을 보였다.

At Haeundae Beach in Busan, people were swept away by the fast-moving rip current and rescued, on August 13th and 15th, 2009 & July 29th and 30th, 2010. In predicting the wave-induced current and consequent tube movement for public safety, the coastal flows and waves are calculated at each time step and grid point by means of systematic interfacing of hydrodynamic and wave models (Lee, 2001). To provide a user-friendly simulation tool for end-users, the forecasting system has been built in a software package called HAECUM. Outputs from the system are viewed as graphs of tube positions with combined current vectors for easy decision of emergency management officials. The tube-wave interaction is taken into account and the traces of swim tube are simulated by using a Lagrangian random walk (Chorin, 1978; Lee, 1994). In this study, we use the Lee's approach (Lee, 1993) in estimating the surface onshore currents due to wave breaking.
