The purpose of this study is to examine feasibility of the 'Master Plan of 2013 Slow Food Expo(2013 AsiO Gusto), Korea' and to analyze the following economic effect. To this end, we used existing data and statistics, and estimated the demand by means of survey for people's traveling and questionnaires for ordinary Koreans. For examining financial feasibility for hosting the Expo, BC ratio (Benefit-Cost Ratio) and NPV (Net Present Value) was applied. For estimating the economic effect following the Expo, the effect on all over the country and the Gyeong-gi province was analyzed, using the MRIO (Model of Regional Input-Output). Specifically, with the net effect of Expo, the economic feasibility test shows 1.04~2.15 BC ratio with 10% free admission, and 1.02~2.27 BC ratio in Finance analysis. Furthermore, the Expo feeds through Gyeong-gi (including Nam-yang-ku) regional economies with production induction effect, value-added induction effect, and employment induction effect. The amounts of regional effects are 373.6~738.7 billion won, 166.2~327.4 billion won, and 1,971~2,009 persons, respectively. Also, the "2013 Slow Food Expo, Korea" was analyzed profitable in general. Residents in Nam-yang-ju expects the Expo to bring vitalities into their hometown. The Expo is highly related to the positive economic effectiveness of Nam-yang-ju.

In this research, the effect of normal load, sliding velocity, and texture density on thefriction coefficient of surfaces micro-textured on AISI 4140 under paraffin oil lubrication were investigated. The predicted tribological behavior by numerical calculation can be serves as guidance for the designer during the machine development stage. Therefore, in this research friction coefficient prediction model based on response surface methodology (RSM), support vector machine (SVM), and artificial neural network (ANN) were developed. The experimental result shows that the variation of load, speed and texture density were influence the friction coefficient. The RSM, ANN and SVM model was successfully developed based on the experimental data. The ANN model can effectively predict the tribological characteristics of micro-textured AISI 4140 in paraffin oil lubrication condition compare to RSM and SVM.

This study was designed to standardize the recipes and to analyze the nutrients of native local foods of Gyeongsangnamdo region, such as 'euneo-bab', 'aeji-jjim' and 'gijang-eomuk.' The test recipes for each food were prepared according to the information obtained from personal interviews and then supplied to sensory evaluation. All the characteristics of each food were evaluated as 'moderate'. The results of the nutrients analysis of the native local foods using CAN Program 2.0 were as follows: protein and iron were high in 'euneobab', iron and folic acid were high in 'aeji-jjim', and zinc, vitamin A, B$_{6}$, and folic acid were high in 'gijang-eomuk', while all three native local foods were low in calories. In case of amino acid composition, all three native local foods were high in glutamic acid, aspartic acid and arginine content. 'Gij ang-eomuk' was higher in fatty acid contents than the other foods, especially, high in linolenic acid and linoleic acid.
