CONSUMER ATTITUDE TOWARD OUTLET STORES AND RETAILER LOYALTY ACCORDING TO CONSUMER SHOPPING TYPEs
Minjae Seo 글로벌지식마케팅경영학회 2014 Global Marketing Conference Vol.2014 No.5
Modern consumers have significantly changed their shopping patterns, so that retailers must employ competitive and innovative strategies to counter the many new types of stores such as outlets offering premium services. In addition, customers have become smarter shoppers, refusing to pay more because of brand loyalty, especially when service and price differences have diminished. This study is an analysis of consumer shopping behavior in an effort to find effective marketing strategies to appeal to consumers who shop in outlet stores. Previous research has shown that shoppers may be clustered according to whether they are oriented toward convenience, brands, hedonism, economics, or trends. Different consumer types have different attitudes toward retailer types and also vary in their retailer loyalty. Some types have strong customer loyalty to outlet stores, but others do not. In this study, we examine the relationship between consumer attitude toward the outlet store and retailer loyalty according to consumer shopping types. Hedonism-oriented and economics-orientated consumers are expected to have more interest in outlet shopping than are brand-oriented consumers.

Two entomopathogenic bacteria, Xenorhabdus nematophila (Xn) and Photorhabdus temperata temperata (Ptt), maintain monoxenic condition within host insect cadaver by synthesizing and releasing various antibiotics. These two bacteria were cultured in tryptic soy broth during different times, which were screened in their antibacterial activities. Both bacterial culture broth had high antibacterial activities against Escherichia coli at their stationary growth phase. The potent culture broth was used to screen target plant bacterial pathogens using both inhibition zone assay and liquid culture assay. Ralstonia sp. was most susceptible, while Xanthomonas sp. was highly resistant. Pseudomonas sp. and Bacillus sp. showed hemi-susceptible. The culture broth was further fractionated into hexane and diethylether extracts. Significant antibacterial effect was found in the diethylether extract
Two-dimensional policy for a warranted system with periodic preventive maintenance
( Minjae Park ) 한국품질경영학회 2022 한국품질경영학회 학술대회 Vol.2022 No.1
This paper considers a two-dimensional warranty policy for a repairable product with increasing failure rate, during which a fixed number of periodic preventive maintenances are provided by the manufacturer or the seller. The preventive maintenance is the common planned action to delay the wearout of the product, while it is still in the operating state. The product is warranted by taking into account both age and usage and the warranty is expired when the product reaches a specified age or specified usage, whichever comes first. In this paper, we develop a cost model to evaluate the expected total warranty cost from the manufacturer’s perspective under a certain cost structure and determine the optimal warranty period under the two-dimensional warranty policy under study. As a practical application of the proposed optimal warranty policy, we present the optimal maintenance strategy under a certain type of lemon law, by which the manufacturer is required to either refund or replace the purchased product if the product failures can’t meet certain conditions of repair thresholds set by the law. In addition, we discuss the optimal premium prices for the warranty policy from the manufacturer’s perspective.

Purpose: Combined hepatocellular carcinoma and cholangiocarcinoma (cHCC-CC) has wide histologic diversity. This study investigated the effects of cHCC-CC histology, according to the 2010 World Health Organization (WHO) classification, on patient prognosis. Methods: The medical records of patients who underwent surgical resection for cHCC-CC at our institution between July 2012 and June 2019 were retrospectively evaluated. Results: During the study period, 168 patients, 122 males (72.6%) and 46 females (27.4%), underwent surgical resection for cHCC-CC, including 159 patients (94.6%) who underwent R0 resection. Mean tumor diameter was 4.4 ± 2.8 cm, and 161 patients (95.8%) had solitary tumors. Histologically, 86 patients (51.2%) had classical type, and 82 (48.8%) had tumors with stem cell (SC) features, including 33 (19.6%) with intermediate-cell and 23 (13.7%) each with typical SC and cholangiolocellular features; 3 tumors (1.8%) were unclassifiable. At 1, 3, and 5 years, tumor recurrence rates were 31.9%, 49.6%, and 58.1%, respectively, and patient survival rates were 91.0%, 70.2%, and 60.3%, respectively. Univariate analysis showed that tumor size of >5 cm, microscopic and macroscopic vascular invasion, lymph node metastasis, 8th edition of the American Joint Committee on Cancer (AJCC) tumor stage, and 2010 WHO classification were significantly prognostic. Multivariate analysis showed that the 8th AJCC tumor stage and 2010 WHO histologic classification were independently prognostic for tumor recurrence and patient survival. There were no significant prognostic differences among the 3 SC subtypes. Conclusion: Postresection outcomes are better in patients with SC-type than with classical-type cHCC-CC.

Most vision-based landing algorithms cannot be applied in a severe vision-detection environment. However, the application of a deep learning technique to vision-based landing algorithm can solve the problem of a severe vision-detection environment, especially in vision-impaired environments. Based on this fact, a novel-landing concept with deep learning technique is proposed in this study. Three main techniques applied for guided landing are 1) deep learning for accurate landing mark detection; 2) location-memorized system for coping temporal failure of the landing mark detection; 3) Unmanned Aerial Vehicle control algorithm for vibration minimization in vision sensor. The proposed system successfully and accurately guided the multicopter onto the landing area without failure in vision-impaired environments. The results show that the proposed landing algorithm can overcome environmental restrictions in operating multicopters.

Background: To retrospectively investigate the use of angiography as a diagnostic tool and evaluate technical and clinical efficacy of transcatheter arterial embolization (TAE) in Crohn’s disease-related gastrointestinal (GI) bleeding. Methods: Institutional Review Board approval with waiver of patients’ informed consent requirement was obtained. There were 39 angiographies performed in 24 patients (male:female = 18:6, median age = 25 years) presenting with Crohn’s disease-related GI bleeding between 2001 and 2014. The technical and clinical success rate of TAE as well as procedure-related complications and 2-year mortality rate were evaluated. Clinical factors such as vital signs and laboratory findings as well as other modalities of investigations were analyzed.Results: Among 39 angiographies, 25.6% of angiographies were performed as the initial choice of investigation and angiography was performed after endoscopy failed to identify a bleeding site in 33.3%. There were negative angiographic findings in 66.7% (26/39). TAE (n = 13) demonstrated 100% technical success rate and 69.2% (9/13) clinical success rate with one case of ischemic complication and one case of mortality due to combined pneumonia. Ileal branches were the most frequent site of embolization and the combination of gelatin sponge slurry and microcoil was most com-monly used.Conclusion: Angiography and TAE may be the initial or follow-up management option in patients with Crohn’s disease presenting with acute GI bleeding. Although the rate of negative angiographic findings was high (66.7%), TAE showed high technical success rate and acceptable clinical suc-cess rate in patients with positive angiographic findings.
