This study was undertaken to examine the quality characteristics of nonblanched carrots (CON) and carrots blanched in distilled water, 2% NaCl water and 2% citric acid at 100℃ for 3 minutes. This moisture contents of CON was the highest at 85.91%, whereas NT had the lowest moisture at 83.92% (p<0.01). Compared to CON values the L values of pretreatment groups were decreased whereas the b values were increased (p<0.001) A comparison of true retention (TR), revealed that NT had the highest TPC TR 101.04% and TFC TR 91.59% (p<0.001). β-Carotene contents were determined to be higher in NT (1.98 mg/100 g) and CT (1.94 mg/100 g) than in other groups, with highest levels obtained in NT (106.64%) (p<0.001). Examination of the DPPH and ABTS+ radical scavenging activities revealed that the NT group had maximum scavenging activity. The total bacterial count was determined to be 3.37 log CFU/g in the CON, whereas no microorganisms were observed in all the pretreatment groups. Our study indicates that blanching in 2% NaCl water is the most desirable in order to increase the biochemical content and nutrient preservation rate of carrots, and to inhibit the growth of microorganisms.

Online games belong to a technology-oriented service industry that has emerged from the assimilation of game contents and communication networks in the respective realms of culture technology (CT) and information technology (IT). This study examines the individual acceptance of online games as entertainment-oriented technology based on the belief-attitude-intention paradigm and the underlying hedonic and utilitarian motivations. To measure the latent variables influencing the acceptance process, a structured questionnaire was developed based on the existing Technology Acceptance Model. Research model analysis and hypothesis testing were carried out using a structural equation model. Results indicated that latent variables reflecting hedonic and utilitarian characteristics had a significant influence on user behavior in the acceptance of online games. By uncovering the core factors in! fluencing the acceptance of online games and thereby theoretically verifying the latent variables influencing the acceptance of entertainment-oriented technology, this study provides strategic implications for business models by game companies aimed at attracting a large user base and dominating the market.

The purpose of this study are as follows. First, to analyze relative LQ index of the No. of character company, the No. of employee and the amount of revenue. Second, to analyze the strength and weakness about technology competence, human resource competence, infra competence and network competence of regional character contents R&D. The results are as follows. The relative competitively LQ index results of company infra indicated all regional area are over 1 LQ index. But, in case of except of seoul & kyunggi, the competence LQ index of R&D which is jeju, dongnam(pusan & kyungnam) are in order. Final result suggested that the high competitiveness of regional character industry are seoul & kyunggi, jeju, dongnam area.
