本 論文에서는 各 basic block間의 global data analysis에 依해 microoperation(Mop's)을 효율적인 microins truction(MI's)으로 결합하는 廣域的 最適化(Global compaction) 알고리즘을 提案한다. 즉, microprogram의 廣域的 고찰을 통해 全體遂行時間 및 製御記憶容量을 減少시킨다. 또한, 알고리즘을 프로그램하고 가상 machine에 적용하여 本 알고리즘의 最適化를 立證한다. In this paper, a global compaction algorithm of microprograms, which combines microoperations (MOP's) into effective microinstructions (MI's) by global data analysis over basic blocks, is proposed. The algorithm reduces total execution time and control memory space, and improves the execution efficiency through a broad view of microprograms. Also, it is implemented and tested on virtual machine, and the result of it's compaction is verified.

The use of waste battery waste has become an issue due to the rapid increase in the use of trains and secondary batteries. It is urgent to develop the same lightweight metal material and develop anode material technology. The safety problem of the battery for the electric vehicle continues to continue, and recently, the toxic gas problem due to the explosion of the electric vehicle battery has also been raised. In this study, the battery was disassembled into a module from a battery for an electric vehicle, and separated from the module into a circuit board, a battery cell, and a frame. After the separation of the anode cathode material and the Al case from the battery cell through repair and dis assembly, the anode cathode material Was dried by discharging in distilled water, and separated into a separator, an anode, and a cathode. In order to recover the positive electrode active material, the positive electrode active material is concentrated in the positive electrode material through pulverization particle size separation on the positive electrode material, and Al, an impurity, is separated in this process. As a chemical treatment method, a leaching experiment was conducted using sulfuric acid and a reducing agent to prepare a precursor for a positive electrode active material of Samsung based on pulverized products obtained through particle size separation. Then, a positive electrode active material was prepared using a co-precipitation method as a target for the leaching solution from which impurities were removed. After the co-precipitation, the remaining lithium filtrate was precipitated with lithium carbonate solution, filtered, washed with water, and recovered with lithium carbonate. Cost reduction is expected by applying this technology to recover and materialize valuable metals.

Odors emitted from pig houses have been a constant root of legal issues in pig farming. These gases are among the main causes of health and mental stresses to nearby communities, so policymakers and researchers continuously study to reduce the concentration of odorous gases from pig facilities. A continuous field experiment proved that the concentration of odor emissions inside the pig houses is highly dependent on ventilation rate, breeding details, and animal activities. However, the standard odor emission rate worldwide widely varies due to differences in pig house designs and ventilation requirements. Thus, this study aimed to measure the odor emission rates, considering the actual condition of selected Korean pig houses, through field measurement. The odor measurements were performed at three different pig production facilities without odor abatement technologies. The target experimental pig houses were buildings for weaning, growing, and fattening pigs. Results showed that the actual ventilation rate in target pig houses falls below the standard ventilation requirement of pigs, resulting in high odor concentrations inside the pig houses.
