The objective of this study is to investigate the effect of additives on the mechanical and electrical characteristics of electrodeposited copper foils. Additives A(leveler) and B(brightener) were used in this study and Cl ions were used as an accelerator. In case of using these additives A and B, it showed a disadvantage that decreased the elongation of electrodeposited layer due to decreased grain sizes and increased tensile strength. On the other hand, the Cl ions decreased the specific resistance of the copper layer and increased elongation owing to increasing grain sizes. The highest elongation and lowest resistivity were measured in the group added only Cl ions, whose values were 21.9% and $3.11{\mu}\Omega$-cm, respectively.

Various infectious diseases have threatened swine industries in Korea. One of the major risk factors of disease spread is livestock transport vehicle. For this reason, all abattoirs are required by law to have vehicle washing and disinfection facilities. However, detailed guidelines for cleaning and disinfection procedures were not provided. So in this study, assessment by visual observation was conducted to evaluate how well the cleaning and disinfection procedures of livestock transport vehicles have been performed in four different abattoirs in Jeonbuk, Korea. The observation included length of car washing time, the number of washing bay, type of washperson, type of disinfectant application, length of disinfection time, and compliance of driver's hygienic procedure. Every vehicle in all abattoirs conducted washing and disinfection procedure. However, there were procedural differences for each abattoirs and defects in the washing and disinfection procedures. In addition to that, the compliance of driver's hygienic procedure was not sufficient. Hence, detailed manuals on washing and disinfection procedures for involved people are required and it is necessary to establish an inspection and evaluation system.

In this work, we report basic performance test results of a lab-scale three phase alternative current (AC) arc plasma torch system for plasma gas reforming applications. The suggested system primarily consists of three graphite electrodes inclined at 12.5° to the central axis, a 𝞥 150 mm cylindrical gas path and a three phase-60 Hz AC power supply. At air flow rate of 50 Lpm and arc currents of 100-175 A, test results revealed that plasma resistances were decreasing from 1.08 Ω to 0.53 Ω with the increase of plasma power from 9.3 kW to 13.8 kW, causing the decrease of power factor and increase of the line voltages. However, the injected air can be heated quickly up to the temperatures of >1,200℃ when injecting AC arc plasma powers of >10 kW.
