The Analysis of Beijing Tourism Destination Image Based on the Network Texts
Wu Jialin,Zheng Miao,Han Xu 한국무역전시학회 2021 무역전시연구 Vol.16 No.4
정보통신기술의 발달로 인해 잠재 관광객은 인터넷으로 여행 정보를 수집한다. 관광 객들은 온라인 플랫폼에서 여행과 관련된 계획, 전략 등을 포스팅하고 여행 경험을 공 유한다. 이러한 온라인 텍스트는 관광객의 경험과 느낌을 주관적으로 설명한다. 본 연 구는 이러한 텍스트를 기반으로 목적지 이미지를 분석하고자 하였다. 본 연구는 Ctrip.com에 게시된 여행 관련 텍스트 중 베이징의 사례를 수집하여 정리하였다. ROST CM6 소프트웨어를 사용하여 빈도가 높은 특징 단어를 추출하고, 네트워크 텍스트 분석 을 사용하여 베이징의 인지적 이미지, 정서적 이미지 및 추천의도를 분석하였다. 연구 결과, 관광객은 목적지의 관광명소에 대한 인지적 이미지가 가장 강하게 나타나 는 것으로 나타났다. 정서적 이미지는 관광객의 긍정적인 감정에 영향을 주지만, 추천 의도를 명확하게 나타내지는 않았다. 분석된 결과를 바탕으로 베이징의 관광지 이미지 제고를 위한 시사점을 제시하였다. With the development of internet, potential tourists began to search travel information of destination through the internet. At the same time, tourists also share their travel experiences by publishing travel notes and tips on online social platforms. These online texts from tourists describe their experiences and feelings of the destination from a subjective perspective, are also providing original data of destination image for researchers. This paper takes Beijing as a case study site, collected travel notes on Ctrip.com, used ROST CM6 to extract high-frequency feature words, and used network text analysis to analyze Beijing’s cognitive image, emotional image, and recommendation intentions. It can be found that the tourists have the strongest perception of the tourist attractions in the cognitive image, and shown a positive emotional image. Otherwise, the recommendation intention is not very clear. According to the results, relevant destination strategies to enhance the image of Beijing’s are proposed.

Effect of serotonin on the cell viability of the bovine mammary alveolar cell-T (MAC-T) cell line
Xusheng Dong,Chen Liu,Jialin Miao,Xueyan Lin,Yun Wang,Zhong-Hua Wang,Qiuling Hou 한국축산학회 2022 한국축산학회지 Vol.64 No.5
5-Hydroxytryptamine (5-HT), a monoamine, as a local regulator in the mammary gland is achemical signal produced by the mammary epithelium cell. In cows, studies have shown that5-HT is associated with epithelial cell apoptosis during the degenerative phase of the mammarygland. However, studies in other tissues have shown that 5-HT can effectively promotecell viability. Whether 5-HT could have an effect on mammary cell viability in dairy cows isstill unknown. The purpose of this study was to determine: (1) effect of 5-HT on the viability ofbovine mammary epithelial cells and its related signaling pathways, (2) interaction betweenprolactin (PRL) and 5-HT on the cell viability. The bovine mammary alveolar cell-T (MAC-T)were cultured with different concentrations of 5-HT for 12, 24, 48 or 72 hours, and then wereassayed using cell counting kit-8, polymerase chain reaction (PCR) and immunobloting. Theresults suggested that 20 μM 5-HT treatment for 12 or 24 h promote cell viability, which wasmainly induced by the activation of 5-HT receptor (5-HTR) 1B and 4, because the increasecaused by 5-HT vanished when 5-HTR 1B and 4 was blocked by SB224289 and SB204070. And protein expression of mammalian target of rapamycin (mTOR), eukaryotic translationelongation factor 2 (eEF2), janus kinase 2 (JAK2) and signal transducer and activator of transcription5 (STAT5) were decreased after blocking 5-HT 1B and 4 receptors. When MAC-Tcells were treated with 5-HT and PRL simultaneously for 24 h, both the cell viability and thelevel of mTOR protein were significantly higher than that cultured with 5-HT or PRL alone. Inconclusion, our study suggested that 5-HT promotes the viability of MAC-T cells by 5-HTR1B and/or 4. Furthermore, there is a reciprocal relationship between PRL and 5-HT.
