Purpose - This paper investigates how consumers' feelings of guilt affect their preference for imported products. Choosing imported products over domestic products reveals that consumers' motivation is to improve themselves. This study also tries to examine whether choosing imported goods has a restorative effect on feelings of guilt. Design/methodology/approach - We ran two experiments to test our hypothesis. Participants were recruited in China and the data analysis software used in this study was SPSS 26.0 for analysis. Findings - The results show that consumers with guilt feelings are more likely to import products than to consume domestic products, the second result shows that choosing imported products has an effect on guilt. In addition, consumers with low self-efficacy in a guilty condition prefer imported products to domestic products. Research implications or Originality - Based on previous research that focused on how guilt activates consumers' self-improvement goals, this study shows that when consumers experience feelings of guilt, they prefer imported products to reduce their negative feelings. These findings are discussed in the light of their implications for research on consumer self-motivation and ways of coping with it.

Although upper respiratory tract infections (URTIs) are common diseases, there have been no studies of their relationship with the indices obtained from tongue image analyses. The purpose of this study was to identify a tongue index through an analysis of tongue images (TIs) showing significant changes before and after treatment in patients with URTIs. A computerized tongue image acquisition system was developed to acquire TIs from subjects in the same environment. An image was taken from each of 39 URTI patients and 39 healthy controls. For the patients, images were acquired before and after treatment to identify changes. The tongue area was classified into a tongue body and a tongue coating, and the coating ratio between the two areas, the average value of the colour of each area, and teeth marks were calculated. No significant difference was observed in age or sex between the URTI patients and control participants. Heart rates were slightly different. The analysis of TIs showed that the luminance of the tongue coating and the coating area ratio were decreased, while the reddish value of the tongue body at the centre area increased as the treatment progressed. Tongue coating and body in URTIs had different colour and shape from those in the normal. It is expected that this result will contribute not only to the objectification of traditional Chinese medicine but also to diagnostic methods that do not involve face-to-face physician visit during the pandemic.

This study was conducted to examine the current status of traditional korean medicine studies on gastroesophageal reflux disease in Korea, identify deficiencies, and suggest the direction of future medicine research methods to lay the foundation for traditional korean medicine treatment. All domestic papers on the korean traditional treatment of gastroesophageal reflux disease were selected among the literature published until August 2022 in six domestic databases. A total of 52 selected research data were classified into experimental research papers, clinical research papers, and review papers. In experimental papers, to evaluate the effectiveness of treatment, improvement of esophageal mucosal lesions, anti-inflammatory mechanisms, antioxidant mechanisms, esophageal mucosal protection mechanisms, gastric peristalsis control, and gastric acid secretion inhibition mechanisms were used as evaluation measures. In the clinical research paper, the basis for diagnosis of cases was clinical symptoms through medical history listening and diagnosis through visits to hospitals in the past. The average treatment period was 40.7 days, and the duration of treatment was not significantly affected by the duration of the disease. The most widely used Korean medicine treatment intervention was herbal medicine. There were 3 literature review studies, 3 systematic literature review and meta-analysis studies, 1 comparative review study for clinical trial guideline development, all using Chinese papers. This study included all domestic papers on gastroesophageal reflux disease to identify the research trend of the Korean oriental medicine community, and based on this, it is meaningful to confirm areas that need to be supplemented in future research plans.

Objectives Mibyeong is an ideological concept that means the state between the healthy and diseased conditions. The purpose of this study was to suggest a research direction to establish the diagnostic criteria for the Mibyeong by reviewing the research results for the Mibyeong. Methods Academic databases (OASIS for Korean database, Embase for English database, and CNKI for Chinese database) were used to search related literatures, and articles describing the concept or diagnostic criteria of the disease were selected. Results The concept of Mibyeong consisted of three different conditions: (1) subjective symptoms without a specific disease, (2) abnormal examination findings without a specific disease, and (3) a state in between health and disease. No matter which of the three conditions is applied, the spectrum of condition was very wide and diverse. Conclusions It is impossible to apply appropriate and monolithic diagnostic criteria to all types of Mibyeong. Therefore, we suggests that the Mibyeong be classified into several subtypes and the diagnostic criteria suitable for each type be established.

This study conducted sentiment analysis on Hong Kong cinema from two distinct eras, pre-2000 and post-2000, examining audience preferences by comparing keywords from movie reviews. Before 2000, positive keywords like 'actors,' 'performance,' and 'atmosphere' revealed the importance of actors' popularity and their performances, while negative keywords such as 'forced' and 'violence' pointed out narrative issues. In contrast, post-2000 cinema emphasized keywords like 'scale,' 'drama,' and 'Yang Yang,' highlighting production scale and engaging narratives as key factors. Negative keywords included 'story,' 'cheesy,' 'acting,' and 'budget,' indicating challenges in storytelling and content quality. Word2Vec analysis further highlighted differences in acting quality and emotional engagement. Pre-2000 cinema focused on 'elegance' and 'excellence' in acting, while post-2000 cinema leaned towards 'tediousness' and 'awkwardness.' In summary, this research underscores the importance of actors, storytelling, and audience empathy in Hong Kong cinema's success. The industry has evolved, with a shift from actors to production quality. These findings have implications for the broader Chinese film industry, emphasizing the need for engaging narratives and quality acting to thrive in evolving cinematic landscapes.

Since 1990s, the use of Complementary and Alternative Medicine(CAM) has been rising rapidly all of the world. In 1983, WHO recommended that the traditional medicine actively be utilized. At the end of 20th century, as chronic and intractable diseases increased in western countries, traditional medicine has attracted considerable attention. COWM shows possibilities of new approaches for these intractable diseases. Thus, we try to show our proper approach of COWM through the international comparative study. In order to fulfill the objectives, we applied the following methodology: 1) Literature review on previous study, 2) Local survey using self-administered questionnaire, and 3) FGI(Focus Group Interview) with local experts. The results were as follows : Three Asian countries, China, Korea and Taiwan, are very active in implementing COWM policy. Japan, however, has independent system of unified medicine. In regards to the combined care policy and system, China has the most advanced COWM system among four countries. In respect to combined care education, it is needed to increase the COWM education contents and the amount of cross educational curriculum. Based on the current COWM system, Chinese, Japanese and Taiwanese doctors can prescribe both oriental and western drugs. But, Korean medical law prohibits western doctors and oriental doctors from prescribing the counterpart´s medicine. So, the revision of current medical law is urgent for COWM in Korea. And when it comes to patient satisfaction, more than fifty percent responded positively in China, Korea and Taiwan. To achieve the goal of COWM ; 1) mutual understanding and recognition of COWM is essential. 2) institutional and legal support system for COWM is desperately urgent. 3) possible international collaboration and cooperation should be sought to untangle these complex cultural dilemmas.

Objectives : Korea and China are applying different conversion standards for weight in traditional medicine books. This study aims to research and suggest how to convert the units of weight in old traditional medicine classics into the contemporary unit of grams. Methods : Historical documents of Korea and China were used to review the process in which weights and measures changed in each country and the manners in which the Chinese units of weight were introduced to Korea. Results : Weights and measures changed with time. They became almost standardized by the period of Song in China, when coins played the most crucial role, and it was introduced to Korea. Donggaryang, the standard container for weights and measures in ancient China, Gaewontongbo, a coin in Tang, Sangpyeongtongbo, a coin in Joseon, and a scale in Joseon were used as strong foundations for conclusion from literature review. Weight of a 1-don(coin) in the time a traditional medicine books were written was used as a unit of weight in those books. Sangpyeongtongbo, a 1-don coin in Joseon, weighs 4 grams on average. Conclusions : Since the current conversion of 1-don coin into 3.75 grams is not supported by literature review, it is suggested that 1-don(coin) as a unit of weight in traditional medicine books of Joseon, may be better converted into 4 grams, while that of China is converted to 3.73 grams.

Polygonatum cyrtonema Lectin (PCL), which is classified as a monocot mannose-binding lectin, has received great regards for its uniquely biological activities and potentially medical applications in cancer cells. This paper was initially aimed to study apoptosis of PCL on Hela cells. Thus, 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) method was carried out. Through observation of cell morphologic changes and Lactate dehydrogenase (LDH) activity-based cytotoxicity assays, PCL induced HeLa cell apoptosis in a dose-dependent manner. To further gain structural basis, multiple alignments, homology modeling and docking experiments were performed to analyze the correlation between its biological activities and mannose-binding sites. Eventually, considering docking data, chemical modification properties on the three mannose-binding sites were analyzed by a series of biological experiments (e.g., hemagglutinating and mitogenic activity assays, fluorescence and Circular Dichrosim (CD) spectroscopy) to profoundly identify the role of some key amino acids in the structure-function relationship of PCL.
