The main goal of this survey was to assess the current sanitation status and safety standards of meat processed products purchased at instant meat sales and processing operators. Analyses were carried out from April to September in 2016 in Gwangju area, Republic of Korea. A total number of 150 samples including seasoned meats, ground meat products, meat extract products, heated seasoned meats, sausages and hams from 35 butcher shops was collected. The number of inappropriate cases was revealed eleven cases (7.3%) in total viable count of bacteria (TVC), total coliform counts (TCC) and Listeria monocytogenes. The reported data indicate that more systemic and technical guidance is needed to monitor instant meat sales and processing operators in order to guarantee safety of meat processed products.

Soil contamination survey was conducted during March - July, 2017 to obtain soil contamination profile of 16 organic and inorganic contaminants in Hanam industrial complex located in Gwangju, Korea. The concentrations of all surveyed contaminants except Cd showed were within 0.3~1.5 times of their natural background levels. Cd showed concentrations as high as 6.9 times of the background level, signifying the influence of the metal processing facilities in the complex. The concentrations of Zn, Pb and Hg in areas nearby industrial facilities were 1.3~5.5 times higher than those within the facility and green area. The concentration of Cu in the green area was 1.4~2.9 times higher than in other areas. The Soil Pollution Index (SPI) analysis revealed 54% of the total area belong to first-grade soil, 43% to second-grade, and 3% to third-grade. The Enrichment Factor (EF) of Zn, Pb, and Cd were 9.2, 15.6, and 88.5, respectively, indicating high accumulation and contamination of the soil with Cd.

To investigate water quality and pollution states of rivers in Gwangju city, total of 30 water samples were taken from the main stream of Yeongsan river, Hwangryong river and Gwangju stream in dry and flood seasons. Physico-chemical characteristics of above streams according to pH-Eh and Piper's diagrams we, typically, assigned to natural river water. In the streams, BOD, COD, T-N and T-P indicating water quality mostly increase toward downstream. Notably, water qualities in area near connection between the Gwangju stream and the main stream of Yeongsan river are polluted over V level in rivers and lakes water quality standard. The pollutions are influenced by lift and agricultural foul waters from Gwangju City and farming areas around upstream branches of the Yeongsan river, reasonably. Besides, heavy metals are below the standard in those streams. So, it is considered that the streams are polluted by not industrial but life/agricultural foul waters.

The smallest green laser containing a built-in temperature controlling unit has been demonstrated. The device volume was just 0.5 cubic centimeters, which is nearly the same size as existing red and blue diode lasers, has an electrical-to-optical conversion efficiency of 10% and 150 mW power output. Furthermore as an alternative approach for compact green laser development, a quasi-phase matching method with wide spectral bandwidth for the reduction of speckle noise will be presented.
