This study aimed at finding the factors impacting customer satisfaction (CS) for conversion farm with 2<SUP>nd</SUP> and 3<SUP>rd</SUP> industry, because the most important thing in the conversion farm is enhancing customer satisfaction. The data on CS from 173 pumpkin farm"s customers by on-line survey were gathered. The analysis using structural equation model with Amos was carried out. Product, service and purchasing were determined as 3 factors impacting to CS. The result showed that purchasing is the biggiest contributor to CS. It means the customers using on-line market are very sensitive to farm"s brand and logistics. It is also found that conversion with processing and farm experience activity is definitely affecting to building customer"s trust. In conclusion, making efforts on enhancing CS in conversion farm is the key to success.

3D NAND Flash cell structures were optimized to improve program efficiency using fully-calibrated TCAD and machine learning (ML) techniques. Program efficiency is determined by the number of charges trapped in the charge trap nitride (CTN) layer at the given program voltage step. Usually, a higher and constant Incremental Step Pulse Programming (ISPP) slope is suitable for various program voltage levels. Using a neural network, we trained a forward model of the relationship between NAND electrical characteristics and structure parameters, then designed a backward model to optimize NAND Flash cell structure having excellent program efficiency. Finally, we validated the optimized NAND structure with TCAD simulation and compared it with hardware reference data.

The incidence of gallstone disease seems to be incerasing and the composition of stone has been changed in Korea. Therefore, a collective review of 4,491 gallstone patients during the last twenty years from January 1973 to December 1992 were carried out at Hanyang university hospital, Seoul, Korea. The total prevlence of localization, physicochemical characteristics, blood type, associated diseases, and the composition of stones were evaluated retrospectively. The statistical analysis was evaluated by Student's t-test. The results are as follows (1)The prevalence among total hospitalized patient was 1.1% and showed increasing tendency annually. (2)The prevalence increased with age, reaching peak in 50 and the male/female was 1:1.13. (3)The prominent clinical manifestations included biliary pain(50.64%), fatty fool intolene(17.14%), jaundice(14.69%), and vomiting(11.73%). (4)The associated diseases were diabetes mellitus(29%), hypertension, chronic liver disease, pacreatitis, and Clonorchiasis. (5)The pigment stones were more prevalent than cholesterol stones(2.5:1), however, choesterol stones seemed to be increasing gradually. These results indicate that in Korea, most gallstones are pigment stones, however, cholesterol stone seems to be increasing, and the overall incidence of gallstone disease is throught to be increasing annually.
