Transglucosylation reaction condition of cyclodextrin glucanotransferase(CGTase) for 2- O -α -glucopyranosyl L-ascorbic acid(AA-2G) production by JK-43 was investigated by high performance liquid chromatography method. CGTase from isolated JK-43 produced AA-2G efficiently using corn starch as a substrate and L-ascorbic acid(AA) as an acceptor. Several AA-2-oligoglucosides produced in this reaction mixture could be converted to AA-2G by additional treatment of glucoamylase. The optimal conditions for the production of AA-2G from AA and corn starch with culture supernatant as an enzyme source were investigated. The optimum temperature for AA-2G production was 55℃, and its optimum pH was around 5.0. CGTase also utilized α-, β - and γ -cyclodextrins, starch, glucose, diastatic solution from malt(the mixture of dextrin, maltopentose, maltotetraose, maltose and glucose) and diastatic solution from rice(the mixture of dextrin, maltotriose, maltose and glucose) as substrates. The reaction mixture (1.5㎖) for the maximal production of AA-2G consisted of 5㎎ of AA, l0㎎ of corn starch, 244units of CGTase. By this reaction mixture, 1.26㎎ of AA-2G, which corresponded to a 25.2% yield based on AA, was produced after incubation of 48 hr at 55℃ (pH 5.0).

This paper examines factors influence on the share of services in international trade of China. In 2004, China overtook Japan as the leading Asian exporter, outdistanced the United States in 2007 and Germany in 2009 as the world’s leading exporter. Since the performance of services in China has shown the competitiveness in international trade for the last decade, it is determined to be the noteworthy field of the economy. In this study, the periodical changes of services in international trade of China were observed with special attention on its assession to the World Trade Organization (WTO). As a theoretical study, qualitative method is used to build a theoretical framework based on the literature review within the context of services and perspective of international trade. Through the analysis on the collected data in Chinese, English, and Korean, the share of services in international trade in China is determined to be influenced by the multiple factors: liberalization processes, development of technology, privatization, governmental policies and planning, and deregulation.

Mobile Consumers in the Travel Service Industry: Focus on Korean Backpackers

배경미 한국인터넷전자상거래학회 2019 인터넷전자상거래연구 Vol.19 No.5

This research paper explores a niche area of travel services industry of international trade in the experience economy – Korean backpackers’ overseas backpacking predisposition may contribute to the understanding and learning of their business activity. According to the most recent statistics, over 28.7 million Koreans which is more than half of the population traveled outside of Korea in 2018 (KTO 2019; MCST 2019). This study employs a grounded analysis approach and an interpretive alternative to deeply investigate the backpacking culture and trends of Korean backpackers based on their experiences abroad through data gathered by in-person interviews and diaries. The research has been conducted based on three distinct backpacker groups in different stages of travel with ethical considerations. First field study was conducted by interviewing the backpackers while they were visiting Europe between 2008 and 2010, the second study over the backpackers who finished their backpacking (post-trip) in 2009 post-trip, and the third study over the experienced backpackers between 2009 and 2017. Throughout the analysis of the examined data about how Korean backpackers sense, feel, think, act, and relate to the things they have experienced in places they have visited it becomes evident that experiential marketing would benefit backpackers and the hospitality industry that services these tourists. Viewing backpacker tourists in general and the niche sub-section of Korean backpackers specifically will aid the hospitality industry to work on building great customer experiences by enhancing the sustainable consumer mobile traveler market.

적색 과육 '홍양' 품종에서 차등발현하는 유전자를 찾기 위하여 mirror orientation selection (MOS)과 결합된 suppression subtractive hybridization (SSH) 실험을 수행하였다. 그 결과, 288개의 cDNA clone을 확보하였으며, colony PCR을 통해 192개의 positive clone을 선발하였고, 이들을 sequencing하였다. NCBI/Genbank 데이터베이스의 BLAST 검색를 We used suppression subtractive hybridization (SSH) combined with mirror orientation selection (MOS) method to screen differentially expressed genes from red-fleshed kiwifruit 'Hongyang'. As a result, the 288 clones were obtained by subcloning PCR product and 192 clones that showed positive clones on colony PCR analysis were selected. All the positive clones were sequenced. After comparisons with the NCBI/Genbank database using the BLAST search revealed that 30 clones showed sequence similarity to genes from other organisms; 10 clones showed significant sequence similarity to known genes. Among these clones, 3 clones (AcF21, AcF42 and AcF106) had sequence homology to 1-aminicyclopropane-carboxylic acid (ACC)-oxidase (ACO) that known to be related to fruit ripening. The expression patterns of differentially expressed genes were further investigated to validate the SSH data by reverse transcription PCR (RT-PCR) and quantitative real-time PCR (qReal-time PCR) analysis. All the data from qReal-time PCR analysis coincide with the results obtained from RT-PCR analysis. Three clones were expressed at higher levels in 'Hongyang' than 'Hayward'. AcF21 was highly expressed in the other genes at 120 days after full bloom (DAFB) and 160 DAFB of 'Hongyang'.
