        Endoscopic ultrasonography-guided intervention has gradually become a standard treatment for peripancreatic fluid collections (PFCs). However, it is difficult to popularize the procedure in Korea because of restrictions on insurance claims regarding the use of endoscopic accessories, as well as the lack of standardized Korean clinical practice guidelines. The Korean Society of Gastrointestinal Endoscopy (appointed a Task Force to develope medical guidelines by referring to the manual for clinical practice guidelines development prepared by the National Evidence-Based Healthcare Collaborating Agency. Previous studies on PFCs were searched, and certain studies were selected with the help of experts. Then, a set of key questions was selected, and treatment guidelines were systematically reviewed. Answers to these questions and recommendations were selected via peer review. This guideline discusses endoscopic management of PFCs and makes recommendations on indication for the procedure, pre-procedural preparations, optimal approach for drainage, procedural considerations (e.g., types of stent, advantages and disadvantages of plastic and metal stents, and accessories), adverse events of endoscopic intervention, and procedural quality issues. This guideline was reviewed by external experts and suggests best practices recommended based on the evidence available at the time of preparation. This will be revised as necessary to address advances and changes in technology and evidence obtained in clinical practice and future studies.

        Acute pancreatitis can range from a mild, self-limiting disease that requires no more than supportive care to severe disease with life-threatening complications. Therefore, to provide a framework for clinicians to manage acute pancreatitis and to improve national health care, the Korean Pancreatobiliary Association (KPBA) established the first Korean guideline for the management of acute pancreatitis in 2013. However, many challenging issues exist, which sometimes lead to differences in practice between clinicians. Taking together the recent dramatic changes of latest knowledge and evidence newly obtained, the committee of the KPBA decided to perform an extensive revision of the guidelines. These revised guidelines were developed by using mainly Delphi methods, and the main topics of these guidelines fall under the following topics: 1) diagnosis, 2) severity assessment, 3) initial treatment, nutritional support, and convalescent treatment, 4) the treatment of local complication and necrotizing pancreatitis. The specific recommendations are presented with the quality of evidence and classification of recommendations.

        The purpose of this study is to investigate the mediating effect of trust when a media broadcaster (such as a disc jockey [DJ]) acting as an information source and the content they provide during live commerce streaming affect acceptance intention. Live commerce is increasing rapidly, offering a new fashion distribution channel by supplementing possible shortcomings of existing online shopping. Data was collected for the empirical study from female consumers in their 20s who actively accepted fashion technology. Statistical analysis of the data was conducted using IBM SPSS Macro Process 3.5. First, the reliability and validity of the variables for information source characteristics, content informativeness, trust, and acceptance intention were verified, and each variable was confirmed as a single factor. Bootstrap analysis was performed using Macro Process Model 4 to reveal the effects of information source characteristics and content informativeness on acceptance intention. As a result of analyzing the mediating effect for each path model with trust as a parameter, it was found that both the direct and indirect effects of the mediating path were significant. This result means that the characteristics of information sources and content informativeness are partially mediated by trust. Therefore, to promote consumer behavior in a live commerce shopping environment, it is necessary to enhance trust. This can be achieved by a media broadcaster with fashion expertise to increase the perception of the attractiveness of the information source and to improve the usefulness of the fashion information being delivered.

        This study examined motivation to use omni-channel services on mobile devices in fashion stores and the effects of such usage motivation on brand purchase intention through continuous and affective commitment. Data were collected on consumers in their 20s and 30s who experienced omni-channel services during shopping for or purchasing fashion products. An online survey asked 413 consumers to rate their brand purchase intention. Sub-levels of each variable were examined using SPSS 25.0, followed by confirmatory factor analysis using AMOS 19.0. In addition, path analysis using structural equation modeling was applied to analyze associations between variables. The statistical results were mixed. First, only two dimensions of usage motivation for omni-channel services, hedonic and relational motivation, had positive effects on continuous and affective commitment. Second, continuous commitment had a greater effect on purchase intention of brands that provided omni-channel services than it did on affective commitment. Third, of the dimensions of usage motivation, utilitarian motivation had a direct influence on purchase intention in the modified model, while social motivation did not affect service commitment and purchase intention. Finally, our findings suggest that brand loyalty can be built by encouraging service commitments through hedonic and relational motivation, based on the usability of omnichannel services.

        Over the past few years, companies have started moving into specific niches in plus-size fashion. The purpose of this study was to verify the marketability of young plus-size clothes in the USA. Data were collected from female consumers aged from 20 to 39 who have experience of purchasing plus-size items. A total of 282 responses were used for statistical analysis. The research result is as follows. First, the obesity stress is affected more by the subjective obesity level than by the objective obesity level and by how people recognize their body types. Second, from an analysis of the factors affecting the shopping orientation of plus-size consumers, style consciousness, pursuing reasonable, emphasizing comfort, and body consciousness are found to be important factors. Third, even if responders are aware of their exact body size, they actively look for the correct size. Fourth, fit evaluation of plus-size products is based on the factors of size fit and movement fit. The respondents were unsatisfied with chest and arm measurements, which deviate widely by body type for tops. Fifth, the overall dissatisfaction with the plus-size market is attributed to the fact that the product assortment range from which to select styles is narrow, and trend reflection is low. Sixth, the respondents tended to avoid fabrics that make their body type more obvious, textures that give the impression of a larger body size, or stiff textures. These results show that the psychological and physical characteristics of obese consumers should be considered to develop products for the young plus-size market.
