Stacey Brown, Florida South- Western State College professor and Human Services Program director, has been credentialed as an approved clinical supervisor from the Center for Credentialing and Education. Brown will hold this credential through 2019. Brown is dedicated to helping others, and actively participates in a variety of professional growth opportunities. Marie Collins, dean of the School of Health Professions, said, “We are so happy for her recent achievement and know that she will continue to advance personally and professionally while cultivating and supervising students in the Human Services program.”

Davidson County Community College (N.C.) welcomed home nationally acclaimed photographer and Lexington native George Grubb as he headlines the college’s annual Fall Art Show. Grubb’s exhibition, titled “Earth’s Vanishing Species,” will be on display in the Mendenhall Building at DCCC’s Davidson Campus through Nov. 6. Grubb has traveled to every continent in the world photographing endangered wildlife. The exhibition includes 36 prints of Grubb’s photography accompanied by commentary of each animal’s threat rating and obstacles to survival derived from the International Union for the Conservation of Nature’s Red List. Many of the animals depicted are rated as “threatened” or worse by the organization. Their greatest threat comes from human activity, either through encroachment of their habitat, poaching, pollution, culling to protect agriculture or other activities. Animals depicted in the exhibition include orangutans in Borneo, Kodiak bears in Alaska, gorillas in Rwanda, Koala bears in Australia, elephants in Kenya, polar bears in the Arctic, walruses in Svalbard and penguins in Antarctica. The Rothschild giraffe, depicted in the exhibit, is the rarest of the nine subspecies of giraffes — only about 500 are believed to live in the wild. All of the animals were photographed in their wild, natural habitat or on a preservation that breeds and introduces them back to the wild.

Off the shores of South Korea, South Dakota School of Mines & Technology Professor Sangchul Bang is making history. Designing suction pile foundations for a 2,500- megawatt (MW) wind farm, his nearly $200,000 contract with Korea Electric Power Corporation Research Institute will result in foundations for 500 windmills ranging from 3 MW to 7 MW each — the largest ever constructed. The world’s current record holder stands at 5.5 MW, a prototype with the potential to power 1,100 households each year. Wind energy currently supplies 3 percent of the world’s electricity and is projected to more than double by 2018, with the World Wind Energy Association predicting a fourfold increase in wind power capacity by 2020. Until 2001, Bang, Ph.D., professor in the Department of Civil & Environmental Engineering, consulted for the U.S. Office of Naval Research, which awarded him a $500,000 grant for the design of mooring systems for floating naval bases approximately one mile long, five times the length of the largest aircraft carrier. Suction pile foundations were the result of that research. He’s been offered numerous Navy research and consulting contracts since then, most recently to supervise the design and installation of the foundations of two meteorological towers installed in preparation for this 2,500-MW wind farm west of South Korea in the Yellow Sea. Prior to the design of offshore wind farms, towers such as these are installed to monitor the meteorological data at the planned site, accruing measurements of atmospheric air pressures, wind velocities and directions, tidal wave conditions and ocean current velocities and directions at various elevations. The data is then used to locate wind turbine orientations and elevations. Housed underneath the towers, embedded in the seafloor, suction pile foundations are large-diameter and hollow, a structure Bang likens to an upside-down cup. Installed with a pump, they suck water out from the top and support the windmill above against external loads such as self-weight, wind, ocean currents, earthquakes, collisions and the like.
