Based on the customer reviews of TripAdviser.com, we intend to define the network of consumers’ words. For data collection, customer reviews were collected by SCTM(Smart Crawling & Text Mining program from April 1, 2013 to August 20, 2017. This study extracted 72 Word that are most frequently used words in restaurants review. The result of CONCOR analysis shows 4 groups and each group have high relationship and strong correlation with each other. Four groups were “Service Quality”, “Food Menu”, “Enjoyable”, and “Local Food”. The results of this study were able to elicit reliable results through reviews from diverse clients and experience, and analyzed the words used in restaurants to find out customer preferences. This study reveals that big data analytics can generate new insights into variables that have been extensively studied in existing hospitality literature. In addition, implications for theory and practice as well as directions for future research are discussed.

Inhibitory effect of moschamine isolated from <i>Carthamus tinctorius</i> on LPS-induced inflammatory mediators via AP-1 and STAT1/3 inactivation in RAW 264.7 macrophages

Jo, A-ra,Han, Hee-soo,Seo, Seunghwan,Shin, Ji-Sun,Lee, Jae Yeol,Kim, Hyoung Ja,Lee, Kyung-Tae Elsevier 2017 Bioorganic & medicinal chemistry letters Vol.27 No.23

<P><B>Abstract</B></P> <P>Seeds of <I>Carthamus tinctorius</I> L. (Compositae) have been used in Korean traditional medicines for the treatment of cardiovascular and bone diseases. In this study, we investigated the anti-inflammatory effects of known serotonin derivatives (<B>1</B>–<B>9</B>) isolated from the ethyl acetate (EtOAc) soluble fraction from the seeds of <I>C. tinctorius</I>. Compound <B>2</B>, identified as moschamine, most potently inhibited lipopolysaccharide (LPS)-induced production of prostaglandin E<SUB>2</SUB> (PGE<SUB>2</SUB>) and nitric oxide (NO) in RAW 264.7 macrophages. Moschamine concentration-dependently inhibited LPS-induced PGE<SUB>2</SUB> and NO production in RAW 264.7 macrophages. Consistent with these findings, moschamine suppressed the protein and mRNA levels of cyclooxygenase-2 (COX-2), microsomal prostaglandin E<SUB>2</SUB> synthase (mPGES)-1, and inducible NO synthase (iNOS), interleukin (IL)-6, and IL-1β. In addition, pretreatment of moschamine significantly inhibited LPS-stimulated the transcriptional activity of activator protein-1 (AP-1) and the phosphorylation of signal transducer and activator of transcription (STAT)1/3 in RAW 264.7 macrophages. Moreover, moschamine inhibited LPS-induced the phosphorylation of p38 mitogen-activated protein kinase (p38) and extracellular signal-regulated kinase (ERK), but it had no effect on c-Jun N-terminal kinase (JNK). These results suggest that the mechanism of anti-inflammatory activity of moschamine is associated with the downregulation of COX-2, mPGES-1, iNOS, IL-6, and IL-1β expression through the suppression of AP-1 and STAT1/3 activation in LPS-induced RAW 264.7 macrophages.</P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

본 연구는 성별에 따라 간호대학생의 자아탄력성과 전문직 자아개념 인식정도의 차이를 분석하고 전문직 자 아개념에 영향을 미치는 요인을 비교하기 위한 서술적 조사연구이다. 서울시 소재 2개 간호대학(과)에 재학하는 학생 445명을 대상으로 하였으며 자료분석방법은 SPSS WIN 18.0 프로그램을 사용하여 서술통계, t-test, χ2.test, Fisher’s exact test, one way ANOVA, Pearson 상관관계, 다중회귀분석을 구하였다. 연구결과 남학생이 여학생에 비해서 자아 탄력성과 전문직 자아개념 정도가 유의하게 높았다. 성별에 따른 일반적 특성별 자아탄력성과 전문직 자아개념과 유 의한 차이를 보인 변수는, 여학생은 학년과 휴학유무, 남학생은 동아리 활동유무이었다. 자아탄력성과 전문직 자아개 념과의 상관관계는 남여학생 모두에서 유의한 긍정적 상관관계를 보였고, 전문직 자아개념에 영향을 미치는 유의한 요인은 자아탄력성이었다. This study was done to analyze the difference in resilience and professional self-concept and compare the influencing factors on Professional Self-Concept among different sexes of nursing students. Subjects were 445 students from two nursing schools in the Seoul city. Data were analyzed by descriptive statistics, t-test, χ2 – test, Fisher’s exact test, one way ANOVA, Pearson correlation coefficients, and multiple regression using the SPSS WIN 18.0 program. Male students had much better resilience and professional self-concept than female students. Variables which were significant differences in resilience and professional self-concept according to sexes were in the females’ case, grade and leave of absence and in the males’ case, club activities. There was a positive correlation between resilience and professional self-concept both sexes. In both groups, the factor that affected professional self-concept was resilience.

정치효능감이 집회 · 시위 참여에 미치는 영향 : 집회 · 시위에 대한 일반적 인식을 포함하여

조아라 ( Jo A Ra ),서인석 ( Seo In Seok ) 안양대학교 복지행정연구소 2018 福祉行政硏究 Vol.34 No.0

개인이 집회 · 시위 참여에 미치는 요인들 중에서 정치 효능감과 집회 · 시위의 일반적 인식을 요인으로 설정하여 가설을 세웠고, 설문조사를 통해 자료를 분석한 결과 정치 효능감과 일반적 인식은 집회 · 참여에 긍정적이거나 부정적인 영향을 미친다는 유의미한 결과를 얻을 수 있었다. 정치 효능감 중 자신의 정치 의사가 정치 과정에 반영되지 않는다고 생각할수록 집회 · 시위에 참여할 가능성이 높다는 결과가 나왔다. 이는 정치효능감이 클수록 정치 참여에 긍정적인 영향을 준다는 기존의 연구와는 다른 결과를 보여준다. 이 차이는 낮은 정치신뢰감 또한 높은 정치참여의 모습을 보인다고 한 겜슨(Gamson, 1968; 1971)에 따라 설명할 수 있다. 자신의 정치의사가 정치 과정에 반영이 되지 않는다는 것은 정치에 대한 불신감을 가지고 있다고 할 수 있다. 따라서 이러한 낮은 정치 신뢰감으로 인해 집회 · 시위에 참여에 영향을 미친 것이라 생각된다. Among the factors affecting individuals’ participation in rallies and demonstrations, we hypothesized the political efficacy and general awareness of rallies and demonstrations, and the analysis of the data showed that political efficacy and general awareness had a significant positive or negative effect on assembly and participation. The more politically effective people think their political intentions are not reflected in the political process, the more likely they will participate in rallies and demonstrations. This shows a different result from previous research that shows that the greater the political effectiveness, the more positive the political participation. This difference can be explained by Gamson (Gamson, 1968; 1971) who said low political confidence also shows a high level of political participation. It can be said that one’s political views are not reflected in the political process. Therefore, such low political confidence may have affected participation in rallies and demonstrations.

Molecular characterization and expression of a disintegrin and metalloproteinase with thrombospondin motifs 8 in chicken

Lee, Ra Ham,Lee, Seokhyun,Kim, Yu Ra,Kim, Sung-Jo,Lee, Hak-Kyo,Song, Ki-Duk Asian Australasian Association of Animal Productio 2018 Animal Bioscience Vol.31 No.8

Objective: A disintegrin and metallopeptidase with thrombospondin motifs type 8 (ADAMTS8) is crucial for diverse physiological processes, such as inflammation, tissue morphogenesis, and tumorigenesis. The chicken ADAMTS8 (chADAMTS8) gene was differentially expressed in the kidney following exposure to different calcium concentrations, suggesting a pathological role of this protein in metabolic diseases. We aimed to examine the molecular characteristics of chADAMTS8 and analyze the gene-expression differences in response to toll-like receptor 3 (TLR3) stimulation. Methods: The ADAMTS8 mRNA and amino acid sequences of various species (chicken, duck, cow, mouse, rat, human, chimpanzee, pig, and horse) were retrieved from the Ensembl database and subjected to bioinformatics analyses. Reverse-transcription polymerase chain reaction (RT-PCR) and quantitative PCR (qPCR) experiments were performed with various chicken tissues and the chicken fibroblast DF-1 cell line, which was stimulated with polyinosinic-polycytidylic acid (poly[I:C]; a TLR3 ligand). Results: The chADAMTS8 gene was predicted to contain three thrombospondin type 1 (TSP1) domains, whose amino acid sequences shared homology among the different species, whereas sequences outside the TSP1 domains (especially the amino-terminal region) were very dif­ferent. Phylogenetic analysis revealed that chADAMTS8 is evolutionarily clustered in the same clade with that of the duck. chADAMTS8 mRNA was broadly expressed in chicken tissues, and the expression was significantly up-regulated in the DF-1 cells in response to poly(I:C) stimulation (p<0.05). These results showed that chADAMTS8 may be a target gene for TLR3 signaling. Conclusion: In this report, the genetic information of chADAMTS8 gene, its expression in chicken tissues, and chicken DF-1 cells under the stimulation of TLR3 were shown. The result suggests that chADAMTS8 expression may be induced by viral infection and correlated with TLR3-mediated signaling pathway. Further study of the function of chADAMTS8 during TLR3-dependent inflammation (which represents RNA viral infection) is needed and it will also be important to examine the molecular mechanisms during different regulation, depending on innate immune receptor activation.

Effects of Pregnancy Stress and Social Support on Maternal-Fetal Attachment in Pregnant Women

A Ra Jo,Yoon Goo Noh 한국간호과학회 2021 한국간호과학회 학술대회 Vol.2021 No.10

Aim(s): The purpose of this study was to identify the effects of pregnancy stress and social support on maternal-fetal attachment in pregnant women. Method(s): The subjects of this study were 156 pregnant women in their second or third trimester aged 19 years or older who visited the Department of Obstetrics and Gynecology of S General Hospital and K Women"s Hospital in C city for prenatal care. Data were collected from July 22 to August 31, 2019, and measurements included pregnancy stress, social support, and maternal-fetal attachment. Data were analyzed by frequency, percentage, mean, standard deviation, t-test, ANOVA, Scheffe test, Pearson Correlation, and stepwise multiple regression analysis using SPSS/WIN 26.0 program. Result(s): It was found that maternal-fetal attachment was negatively correlated with pregnancy stress (r=-.281, p<.001), whereas a positive correlation was observed with social support (r=.457, p<.001). Pregnancy stress had a negative correlation with social support (r=-.276, p<.001). Factors that affect maternal-fetal attachment include friend support (β=.227, p=.010), prenatal education (β=.205, p=.003), gestational age (third trimester) (β =.199, p=.004), support from special person (β=.194, p=.026), and current health status (β=.143, p=.038), and the explanation power was 31.5% (F=12.88, p<.001). Conclusion(s): Our study shows that pregnancy stress and social support plays a significant role in maternal-fetal attachment. For better maternal-fetal attachment, it is important to pay attention to the support from friends and special persons, the prenatal program, and the health status of the pregnant women. The results of this study will serve as basic data for the development of strategies for improving fetal attachment in pregnant women.
