  • Purpose - Korean exports account for a vast proportion of Korean GDP, and large volumes of Korean products are sold in the United States. Identifying and characterizing actual and potential product hazards related to Korean products is critical to safeguard Korean export trade, as severe quality issues can impair Korea's reputation and reduce global consumer confidence in Korean products. In this study, we develop country-of-origin-based product risk analysis methods for social media with a specific focus on Korean-labeled products, for the purpose of safeguarding Korean export trade. Design/methodology - We employed two social media datasets containing consumer-generated product reviews. Sentiment analysis is a popular text mining technique used to quantify the type and amount of emotion that is expressed in the text. It is a useful tool for gathering customer opinions regarding products. Findings - We document and discuss the specific potential risks found in Korean-labeled products and explain their implications for safeguarding Korean export trade. Finally, we analyze the false positive matches that arise from the established dictionaries that were used for risk discovery and utilize these classification errors to suggest opportunities for the future refinement of the associated automated text analytic methods. Originality/value - Various studies have used online feedback from social media to analyze product defects. However, none of them links their findings to trade promotion and the protection of a specific country's exports. Therefore, it is important to fill this research gap, which could help to safeguard export trade in Korea.

  • Purpose: The aim of this study was to examine the nutritional intake status of the lung cancer patients who underwent pulmonary resection and to analyze the relationship between the status of the nutritional intake and the occurrence of postoperative pulmonary complications. Methods: This study was a secondary analysis to determine whether the changes in the nutritional intake after surgery were related to pulmonary complications. Data of a total of 89 patients were included in the analysis and the nutritional intake status was confirmed using a 24-hour dietary recall method. The data were analyzed by descriptive statistics, chi-square or Fisher's exact test, and ANOVA using the SPSS WIN 26.0 program and word clouds were generated using the R software program. Results: Overall, a decrease in the postoperative nutritional intake was observed in the patients who underwent pulmonary resection, except for the intake of fat. The pulmonary complications were identified to be associated with BMI and the presence of comorbidity. Twenty-three out of 74 patients with vitamin E levels below the Estimated Average Requirements developed pulmonary complications after surgery. Conclusion: Lung cancer patients who underwent pulmonary resection generally have difficulty in acquiring appropriate nutritional intake and need balanced nutritional management. Future investigations on the impact of increased vitamin E intake on postoperative pulmonary complications may provide better insight into the relationship between vitamin E intake and pulmonary complication among patients who underwent pulmonary resection.

  • The aim of this study is to analyze the research trend focusing on Yangseng(養生) studies in Korea. Through this study, the researchers attempt to explore the research trends of the Yangseng(養生) in Traditional Korean Medicine. Yangseng(養生) as a key word was searched on representative domestic databases of articles and the researchers and collected the articles of journals published from 1980 to 2012. Finally 350 articles of Yangseng(養生) were selected. After mid-2000s, Yangseng(養生) studies has been increased with the great interest in quality of life. Taoism and Traditional Korean Medicine were closely related with Yangseng(養生). Most of the Yangseng(養生) Studies in Medicine have been carried out by Traditional Korean Medicine and primarily focused in the literature. Yangseng(養生) has been defined as a sort of health-promoting behaviors. Therefore, Yangseng(養生) studies that mainly analyzed the variables associated with health-related quality of life and Yangseng(養生) and the main subjects were elderly and workers in this study. But every measuring instrument except Yangseng(養生) was adapted from western tools. In order to handle the new wave of society and medicine, new health concept and measuring instrument of Traditional Korean Medicine should be developed through Korean unique ideas of Yangseng(養生).

  • Recently, as growing number of consumers publish product and service reviews on the Internet, e-review has received attention from retailers and researchers. E-review, a form of electronic word-of-mouth (eWOM) which is typically shared between strangers whose identity and credibility are unknown, has become an important product information source as social media has facilitated information exchanges between more consumers. The objective of this study was to investigate the effects of e-review attributes on purchase intention for fashion products, which is mediated by trust of e-review, as well as to explore the differences between consumer communities and cooperative communities. A questionnaire was developed based on previous researches. Data were gathered from adults living in Busan. The results were analyzed by factor analysis, t-test, and regression using SPSS 18.0. The results showed that consumers tended to recognize e-reviews from consumer communities as exaggerated information, while they considered reviews from cooperative communities as reliable information, which gave the latter higher purchase intention. There were significant differences in e-review attributes for fashion products (e.g., Exaggeration, Entertainment, Innocence, and Agreement), purchase intention between consumer communities (e.g: Blog, Internet cafe) and cooperative communities (e.g: general malls and specialty malls). For both communities, purchase intention of fashion products was influenced by its entertainment attributes and perceived trust of e-reviews. These results suggest that e-retailers need to focus on understanding the causes of purchase intention with e-reviews for fashion products. Specifically, e-retailers should recognize that e-reviews of fashion products were associated primarily with entertaining and with consumers' trust. Based on these findings, managerial implications are presented.

  • Metformin is antihyperglycemic, not hypoglycemic. It causes neither insulin release from the pancreas nor hypo glycemia, even when taken in large doses. But, there are several reports of metformin-associated lactic acidosis (MALT). We present a case report of severe lactic acidosis most probably resulting from high doses of metformin in a patient with no known contraindications for metformin. A 43-year-old female was admitted to the emergency department due to a metformin overdose. She had diabetes for 6 years, well-controlled with metformin and novolet. One hour before admission, she impulsively took 50g metformin (100 mg or 100 tablets). Physical examination for symptoms revealed only irritability, and laboratory evaluation revealed only mild leukocytosis. After one hour the patient was drowsy, and arterial blood gas analysis showed severe lactic acidemia Seven hours after ED arrival, she commenced hemofiltration treatment and was admitted to the intensive care unit. Continuous venovenous hemodiafiltration was initiated. Forty-eight hours later, full clinical recovery was observed, with return to a normal serum lactate level. The patient was discharged from the intensive care unit on the third day. A progressive recovery was observed and she was discharged from the general word on the thirteenth day.
