This study investigated the internship experiences of female college students who have participated in consumer counseling programs. The factors that determine interns' counseling time and interns' level of satisfaction with the programs were examined. Major results of this study are summarized in the following. First, interns' time spent on counseling consumers was the longest for the program at the Korean Consumer Protection Board, followed by the programs at consumer agencies and firms. The time spent on counseling by interns was shorter when there was l) a larger number of employees; 2) a smaller proportion of female employees: 3) a larger number of counseling rooms and a higher the frequency of counseling at the agency; and 4) a lower evaluation on the work performance of the counseling agency and the employees. Second, the level of utilization of interns was the highest in consumer agencies, followed by the Korean Consumer Protection Board. When all employees were female and the evaluated level of work performance of the counseling agency and employees was high, the level of intern utilization was also high. Third, the evaluated level of work performance was the highest at the Korean Consumer Protection Board, and interns' satisfaction with the internship program was the highest with the consumer agencies and the Korean Consumer Protection Board. Fourth, interns were highly satisfied with the program when the level of intern utilization was high and the agency's operation was evaluated as good.

The purpose of this experimental study was to investigate the effects of vulcanization condition on the properties of reinforced rubbers. Rubber reinforcing ability of carbon black was more efficient than other fillers, but tensile properties were not affected by vulcanization condition while vulcanization condition affected the physical properties of rubber compounds with silica and silane treated slica. It was found that silica and silane treated silica filled rubber compounds showed good dynamic properties, rebound, heat build-up, 0 and $60^{\circ}C$ tan $\delta$ compared with carbon black filled rubber compounds. Carbon black filled rubber compounds were higher than silica and silane treated silica filled rubber compounds in total crosslinking density by vulcanization condition. By analysis of crosslinking type, polysulfide crosslinking was the highest in the carbon black filled rubber compounds with decreasing the ratio of sulfur to accelerator, monosulfide crosslinking was the highest in the silane treated silica filled compounds with in-creasing the ratio of sulfur to accelerator.

The present study deals with a numerical simulation for the transport phenomena in three configurations of Membrane Distillation (Air Gap, Direct Contact and Sweeping Gas Membrane Distillation) usually used for desalination in order to make an objective comparison between them under the same operating conditions. The models are based on the conservation equations for the mass, momentum, energy and species within the feed saline and cooling solutions as well as on the mass and energy balances on the membrane sides. The theoretical model was validated with available data and was found in good agreement. DCMD configuration provided the highest pure water production while SGMD shows the highest thermal efficiency. Process parameters' impact on each configuration are also presented and discussed.

The Machine Learning has been identified as a promising approach to knowledge-based system development. This study aims to examine the ability of machine learning techniques for farmer's decision making and to develop the reference model for using pig farm data. We compared five machine learning techniques: logistic regression, decision tree, artificial neural network, k-nearest neighbor, and ensemble. All models are well performed to predict the sow's productivity in all parity, showing over 87.6% predictability. The model predictability of total litter size are highest at 91.3% in third parity and decreasing as parity increases. The ensemble is well performed to predict the sow's productivity. The neural network and logistic regression is excellent classifier for all parity. The decision tree and the k-nearest neighbor was not good classifier for all parity. Performance of models varies over models used, showing up to 104% difference in lift values. Artificial Neural network and ensemble models have resulted in highest lift values implying best performance among models.

Dyeing liquor was extracted from flowers, leaves and stems of balsamine. Dyeing properties, colorfastness and antibacterial activities of the fabrics dyed with the balsamine extracts were investigated at a variety of dyeing conditions of differing pH. time and temperature. Wool, silk and nylon fabrics showed better dyeability than cellulosic fabrics, i.e. cotton, linen and rayon. Especially, nylon fabrics showed the highest K/S values. The dye-uptake was achieved to the highest degree during the first ten minutes of dyeing procedure. All fabrics were dyed well at $40^\circ{C}$ with no pH adjustment. The pH of unadjusted balsamine extracts was 4.6. Their colorfastnesses to washing, drycleaning and perspiration were good as 4 or 4-5 grade. but the light fastnesses were poor as 1-2 grade. While, the antibacterial activities to Staphylococcus aureus and Klebsiella pneumoniae were excellent with 99.9% of colonies reduction ratio. Their excellent antibacterial activity was kept well after ten times washing.
