Purpose: The role of salespersons' emotions in effective selling behavior garners attention among scholars and practitioners. Previous studies have investigated the effects of emotional intelligence and emotional labor on sales success separately. However, to understand the whole process, the relationships among salespersons’ cognition, emotions, and behaviors should be considered simultaneously. Accordingly, we uniquely examined how salespersons’ emotional intelligence (emotional antecedent) and customer orientation (cognitive antecedent) influence their emotional labor (deep acting vs. surface acting), adaptive selling behavior, and the selling results in the retail environment. Research design, data, and methodology: To improve methodological rigor, we used the dyadic approach. We measured 182 salespersons’ emotional intelligence, customer orientation, and emotional labor, and 364 customers assessed the salespersons' adaptive selling behavior and selling results in the insurance and duty-free department retailing sectors. Result: The findings suggest that salespersons' customer orientation and emotional intelligence relate to deep-acting of emotional labor, affecting their adaptive selling behavior and relationship quality with customers. Conclusions: As for managerial implications, sales managers may well consider emotional intelligence levels when selecting salespersons in the retail industry. Additionally, practical training programs are required to cultivate customer orientation, emotional intelligence, and deep acting while performing emotional labor.

목적: Rebamipide와 ecabet sodium은 위점막을 보호하여 위염, 위궤양 치료에 사용되며, H. pylori의 증식과 생장을 억제하여 제균 치료에도 이용될 수 있다는 보고가 있다. 본 연구에서는 rebamipide와 ecabet sodium을 PPI, amoxicillin, metronidazole, clarithromycin로 이루어지는 사제 동시 치료에 각각 추가하여 H. pylori의 제균에 어떠한 영향을 미치는지 확인하고자 하였다. 대상 및 방법: H. pylori 제균 치료가 필요한 환자들을 대상으로 PPI를 포함한 non-bismuth 사제 동시 치료, rebamipide추가 치료, ecabet 추가 치료를 각각 시행하였다. 제균율은 치료 종료 4주 후 ¹³C-요소호기 검사를 통해 확인하였다. 결과: 사제 동시 치료군 총 118명 중 97명(82.2%), rebamipide추가 요법군 총 85명 중 77명(90.6%), ecabet sodium 추가요법군 총 74명 중 66명(89.2%)이 제균되었으며, 통계적 유의성은 없었다. 약물 순응도는 세 군에서 차이가 없었으며, 사제동시 치료군(32.2%)보다 rebamipide 추가 요법군(50.6%)에서 통계적으로 유의하게 높은 부작용률을 보였다(p=0.01). 또한 다변량 분석에서 치료 순응도가 감소할수록 H. pylori 제균 실패의 위험도가 유의하게 증가하는 것으로 나타났다(odds ratio 3.52, 95% confidence interval 1.00-12.32; p=0.05). 결론: 본 연구에서는 rebamipide와 ecabet sodium을 기존의 PPI를 포함한 사제 동시 치료에 추가하여도 제균율이 유의하게 증가하지 않았다. 이러한 결과는 높은 항생제 내성과 관련이 있다고 생각되며 향후 전향적인 연구로 확인이 필요해 보인다. 또한 환자의 약물 순응도가 높을수록 H. pylori 제균치료 성공률이 높으므로 동시 치료 처방 시 약물 순응도의 중요성을 환자에게 교육 및 강조할 필요가 있다. Background/Aims: Although some previous studies reported that a treatment combined with mucoprotective agent could improve the eradication rate in dual or triple therapy, there are other reports that question the efficacy of combining these drugs in concomitant therapy (CoCTx). The aim of this study was to investigate the effects of rebamipide or ecabet on the Helicobacter pylori (H. pylori) eradication combined with CoCTx. Methods: We retrospectively reviewed the medical records of 277 patients with proven H. pylori infection. They were assigned to one of 3 regimens for 10 days, twice daily: (a) CoCTx (n=118): lansoprazole 30 mg, amoxicillin 1 g, metronidazole 500 mg, and clarithromycin 500 mg; (b) CoCTx+rebamipide (100 mg) (n=85); (c) CoCTx+ecabet (1 g) (n=74). Results: The baseline characteristics were not significantly different. H. pylori eradication rates were 82.2% (97/118) in CoCTx, 90.6% (77/85) in CoCTx+rebamipide, and 89.2% (66/74) in CoCTx+ecabet (p=0.17), which were statistically insignificant. Overall adverse events were more frequently reported in the CoCTx+rebamipide (50.6%. 43/85) and CoCTx+ecabet (44.6%, 33/74) groups than in the CoCTx (32.2%, 38/118) (p = 0.03) group. Drug compliances were not different between three groups (CoCTx: 95.8%, 113/118; CoCT+rebamipide: 92.9%, 79/85; CoCTx+ecabet 98.6%,73/74) (p=0.209). Multivariate analysis showed that the risk of eradication failure was significantly increased with decreased drug compliance (odds ratio 3.52, 95% confidence interval 1.00-12.32; p=0.05). Conclusions: Addition of these mucoprotective agent was not superior to CoCTx alone for eradicating H. pylori infection with frequent adverse events. Rather, drug compliance is the most related factor affecting the eradication rate. Our data suggest the importance of drug compliance over the drugs used. (Korean J Gastroenterol 2018;71:204-212)

Isolated mediastinal tuberculous lymphadenitis is clinically rare. Its clinical presentation may mimic an esophageal submucosal tumor by extrinsic compression. A 26-year-old woman was referred to our hospital for an esophageal subepithelial tumor. A 15×10 mm sized subepithelial lesion was found 30 cm from the upper incisors on esophagogastroduodenoscopy. We diagnosed the lesion as a submucosal tumor, and performed endoscopic ultrasonography-guided fine needle aspiration for a pathologic diagnosis. The histologic examination revealed granulomatous inflammation consistent with tuberculosis. We suggest that the use of endoscopic ultrasonography and fine needle aspiration may be helpful in making an early diagnosis and planning for an optimal treatment.

Objective: Efficacy or long-term result of metastasectomy for recurrent or metastatic biliary tract carcinoma (BTC) is not well established. We conducted a retrospective review of the outcomes of metastasectomy for recurrent or metastatic BTCs. Methods: The clinicopathological features and outcomes of consecutive patients with BTCs who underwent surgical resection for primary and metastatic disease at a tertiary referral hospital from 2003 to 2013 were reviewed retrospectively. Results: We found 19 eligible patients. Median age of patients was 57 years old (range, 27 to 68 years old), and 11 patients (58%) were female. Primary sites were gallbladder cancer (seven patients, 37%), intrahepatic cholangiocarcinoma (five patients, 26%), distal common bile duct cancer (three patients, 16%), proximal common bile duct cancer (two patients, 11%), and ampulla of Vater cancer (two patients, 11%). Eight patients (42%) had synchronous metastasis, while 11 (58%) had metachronous metastasis. The most common metastatic site was liver (nine patients, 47%), lymph node (nine patients, 47%), and peritoneum (three patients, 16%). Nine patients (47%) achieved R0 resection, while four (21%) and six (32%) patients had R1 and R2 resection, respectively. With a median follow-up period of 26.7 months, the estimated median overall survival (OS) was 18.2 months (95% confidence interval [CI], 13.6 to 22.9 months). Lower Eastern Cooperative Oncology Group performance status (P=0.023), metachronous metastasis (P=0.04), absence of lymph node metastasis (P=0.009), lower numbers of metastatic organs (P<0.001), normal postoperative carbohydrate antigen 19-9 level (P=0.034), and time from diagnosis to metastasectomy more than one year (P=0.019) were identified as prognostic factors for a longer OS after metastasectomy. Conclusion: For recurrent or metastatic BTCs, metastasectomy can be a viable option for selected patients.

( Joonhwan Kim ),( Inkeun Park ),( Young Saing Kim ),( Hee Kyung Ahn ) 대한내과학회 2015 대한내과학회 추계학술대회 Vol.2015 No.1

Purpose: The aim of this study was to verify a prognostic role of sarcopenia in patients with recurrent or metastatic pancreatic cancer receiving gemcitabine based chemotherapy. Materials and Methods: Medical record and computed tomography scan of consecutive patients treated with palliative gemcitabine based chemotherapy from 2008 to 2014 were reviewed. The lumbar skeletal muscle index at 3rd lumbar spine level was computed, and together with clinicolaboratory factors, univariate and multivariable analyses for overall survival (OS) were performed. Results: A total of 88 patients were found. Median age was 65 years, and male patients were predominant (67.0%). Most patients had initially metastatic disease (72.7%), and gemcitabine monotherapy was administered in 29 patients (33.0%) while gemcitabine plus erlotinib was administered in 59 patients (67.0%). Sarcopenia was present in 76 patients (86.3%). With a median follow-up period of 44.32 months (range 0.6-44.3 months), median OS was 5.35 months (95% CI 4.11-6.59 months). In univariate and multivariable analysis, high carcinoembryonic antigen level [hazard ratio (HR) 4.18, 95% CI 1.95-8.97, p<0.001], initially metastatic disease (HR 3.37, 95% CI 1.55-7.32, p=0.002), sarcopenia (HR 2.97, 95% CI 1.20-7.36, p 0.019), neutrophilia (HR 2.94, 95% CI 1.27-6.79, p=0.012), and high lactate dehydrogenase level (HR 1.96, 95% CI 1.07-3.58, p=0.029) were identified as independent prognostic factors for overall survival. Conclusions: Sarcopenia is prevalent and an independent poor prognostic indicator in patients with recurrent or metastatic pancreatic cancer who receive gemcitabine based chemotherapy. These findings may be helpful in prediction of prognosis in clinical practice and can be used as a stratification factor for clinical trials.
