국내 커피전문점의 서비스품질이 고객만족과 고객충성도에 미치는 영향에 관한 연구

한도경 한국외식경영학회 2015 외식경영연구 Vol.18 No.1

본 연구는 국내 커피전문점을 이용한 고객을 대상으로 서비스품질이 고객만족과 고객충성도에 미치는 영향을 파악하고자 하였다. 연구결과, 서비스품질과 고객만족도와의 영향관계에서 종속변수인 고객만족에 대한 전체 설명력(R2)은 47.1%로 나타났고, 서비스 품질과 고객충성도의 영향관계에서 종속변수인 고객충성도에 대한 전체 설명력(R2)은 36.6%로 나타났고, 이 회귀식의 통계적 유의성을 검정하기 위한 통계량인 통계량 값은 157.599로 나타났다. 따라서 서비스품질이 고객충성도에 미치는 영향에 대한 회귀식은 통계적으로 유의성이 있는 것으로 볼 수 있다. 서비스 품질의 각 요인들에 대한 유의성을 판단하기 위한 값의 유의도에 의해 고객충성도에 영향을 미치는 서비스품질 변수로는 확신공감성(t =4.056, p= .000), 커피품질(t =5.359, p= .000)이 유의한 영향을 미치는 것으로 나타났다. 또한 고객만족도가 고객충성도에 미치는 영향을 분석한 결과 고객만족도(t =12.554, p=.000)이 정(+)의 영향을 미치는 것으로 나타나 서비스품질은 고객만족과 고객충성도에 영향을 미친다는 가설은 채택되었다. This study, conducted on customers of the domestic coffee chains, aims to examine the influence service quality has on customer satisfaction and customer loyalty. As a result, the overall explanatory power (R2) on the dependent variable ‘customer satisfaction’ in relation to service quality was found to be 47.1%, and the overall explanatory power (R2) on the dependent ‘customer loyalty’ to service quality was 36.6%. The F-test, which was conducted to show the statistical significance of the regression equation above, showed a value of 157.599, thus proving statistical significance of the regression equation on how service quality affects customer loyalty. The t-test, which was conducted to determine the various variables of service quality that directs to customer loyalty, showed assurance (t =4.056, p= .000) and quality of coffee (t =5.359, p= .000) as statistically significant variables. Furthermore, an analysis on the influence of customer satisfaction on customer loyalty showed positive (+) influence for customer satisfaction (t =12.554, p=.000), therefore the hypothesis that the quality of service affects customer satisfaction and loyalty was adopted.

Objectives : The aim of this study is to review the effect of acupuncture/moxibustion on vitiligo. Methods : Using 5 databases(Pubmed, EMBASE, Cochrane Library, RISS, OASIS) clinical studies about effect of acupuncture/moxibustion on vitiligo were searched. Only randomized controlled trials(RCTs) were selected to analyze. Results : Total 235 studies were searched. After screening those studies 5 studies were selected from china and Iran. 3 studies used effective rate to measure the effect of acupuncture for vitiligo. 1 study used Vitiligo Area Scoring Index(VASI) and 1 study assessed 4 grade of repigmentation to prove acupuncture's effect on vitiligo. All studies showed repigmentation in acupuncture/moxibustion group. Adverse effects reported in the five studies were temporary erythema, itching, and dryness. Conclusions : These findings suggest that acupuncture and moxibustion can be considered a safe treatment for vitiligo. However, due to the small number of RCTs conducted on acupuncture and moxibustion for vitiligo, more RCTs should be conducted to confirm the effectiveness of acupuncture and moxibustion for vitiligo.

Discovering the Anti-cancer Effects of Ligusticum Chuanxiong through Network- based Pharmacology Analysis and Molecular Docking: An Inquiry into Natural Products

한도경,손지원,성의숙,김윤숙,안원근 한국생명과학회 2023 생명과학회지 Vol.33 No.11

In some cases of head and neck cancers (HNC), surgical interventions may result in the loss of organs and/or changes to their functions, thereby significantly affecting the patient’s quality of life. As a result, the surgical treatment of HNC patients is often limited to specific cases, and alternative treatment modalities, such as chemotherapy, are considered. However, serious adverse effects caused by chemotherapy, such as severe nausea and vomiting, necessitate the need for the development of adjunctive methods to minimize patient suffering. Chuanxiong, Ligusticum chuanxiong (L. chuanxiong), is a natural herb used in Eastern medicine to treat cerebrovascular disorders and headaches. This study aimed to predict the effect and potential of L. chuanxiong as an auxiliary anticancer drug through network-based pharmacology and molecular docking analysis. The study results showed that 40 out of 41 genes of L. chuanxiong shared common targets of HNC and their proteins could be used to target HNC cells to prevent cancer progression. The results of the functional enrichment analysis confirmed that L. chuanxiong is associated with the neuroactive-ligand metabolism and neurotransmitter pathways, indicating its potential medicinal value as an adjuvant in HNC treatment. Lastly, our findings demonstrated that the active ingredient of L. chuanxiong, (Z)-Ligustilide, has the ATP binding site of heat shock protein 90, a protein known to promote the activation of cancer cells. These results suggest that L. chuanxiong is a promising candidate for developing auxiliary anticancer drugs, and further research could potentially lead to the discovery of newer and safer anti-cancer agents.

A Case Report of an Elderly Patient with Psoriasis Treated with Jeongri-tang Gagam-bang: Focus on Digestive System Treatment

한도경,안원근 대한한의학회 2023 대한한의학회지 Vol.44 No.4

Objectives: This study aimed to report the efficacy of Korean medicine with Jeongri-tang Gagam-bang for treating psoriasis. Methods: A patient with psoriasis was treated with Jeongri-tang Gagam-bang (正理湯加減方). Moreover, acupuncture was performed on CV12 (中脘) and both sides of ST25 (天樞), GV20 (百會), LI4 (合谷), and LR3 (太衝) for 15 minutes. Psoriasis severity was assessed using the Psoriasis Area and Severity Index (PASI). Pruritis and dyspepsia intensities were ranked on a Visual Analog Scale (VAS) of 0–10. Results: After treatment, the PASI changed from 21.6 to 1.6. Patient’s pruritus had almost disappeared and dyspepsia had improved. Conclusions: This study shows that Jeongri-tang Gagam-bang (正理湯加減方) and acupuncture on CV12 (中脘), ST25 (天樞), GV20 (百會), LI4 (合谷), and LR3 (太衝) might be helpful to treat psoriasis symptoms by improving digestive function.

한도경 대한한의학회 2024 대한한의학회지 Vol.45 No.3

Objectives: The objective of this study is to report three successful cases of tinnitus treatment using thread-embedding therapy. Methods: Thread-embedding therapy was performed on GV20 (百會), CV12 (中脘), and both sides of GB2 (聽會), TE17 (翳風), ST25 (天樞), and ST36 (足三里) for a duration ranging from 2 to 13 sessions. The severity of tinnitus was assessed using the Korean Tinnitus Handicap Inventory (K-THI) and the Verbal Numerical Rating Scale (VNRS). Results: In Case 1, the patient's THI score decreased from 92 to 8, and the VNRS score decreased from 10 to 0. In Case 2, the patient's THI score decreased from 62 to 2, and the VNRS score decreased from 7 to 0. In Case 3, the patient's THI score decreased from 88 to 42, and the VNRS score decreased from 8 to 4. Conclusions: Thread-embedding therapy demonstrated a positive clinical effect in the treatment of tinnitus.

Prediction of the Mechanism of Action for Buguzhi in Vitiligo Treatment through Network Pharmacology Analysis: Focusing on the Regulation of Tumor Protein p53

한도경 대한한의학회 2024 대한한의학회지 Vol.45 No.4

Objectives: This study aimed to predict the mechanism underlying the effects of buguzhi (補骨脂) on vitiligo through network pharmacology analysis and molecular docking. Methods: The active compounds of buguzhi and its related genes were collected through traditional chinese bank (TCM Bank) and encyclopedia of traditional chinese medicine (ETCM) databases. Vitiligo-related genes were collected using Comparative Toxicogenomics Database (CTD), DisGenet, and Gene Cards. The overlapping genes between buguzhi-related genes and vitiligo-related genes were designated target genes. Protein-protein interaction analysis was performed using the STRING for target genes. The top 10 genes and top 3 compounds with high association in the target gene networks were selected as hub genes and compounds using CytoHubba. Functional enrichment analysis was conducted using an the science and research online plot, categorized by biological process (BP), cellular component (CC), and molecular function (MF). Molecular docking was performed using AutoDockTools. Results: Fifty-six target genes were collected. Three hub compounds (uvadex, psoralen, and stearic acid) and 10 hub genes (TP53, BCL2, IL1B, TNF, NFKB1, CASP3, ACTB, INS, FOS, and PTGS2) were revealed. The top-ranked hub gene was TP53. Functional enrichment revealed that the hub genes with the highest enrichment scores in the biological process were those that regulate reactive oxygen species metabolism, nuclear membrane in the cellular component, and tumor necrosis factor superfamily binding and cytokine receptor binding in the molecular function. Psoralen and uvadex stably interacted with tumor protein p53 (TP53) with affinity energies of −4.7 and −4.867 kcal/mol. Conclusions: Buguzhi is predicted to treat vitiligo by regulating p53 to scavenge reactive oxygen species and protect melanocytes from various immune responses induced by oxidative stress, promoting melanogenesis.
