This study was carried out to investigate the effects of supplementation with a Bifidobacteria enhanced yogurt (BE0623 yogurt), which includes Bifidobacterium lactis BB12, Lactobacillus acidophilus, Streptococcus thermophilus, and Bifidobacterium lactis, in the management of irritable bowel syndrome (IBS) using animal models and clinical trials. In a rat study, a loperamide-treated group (LOP) showed reduced water content in fecal pellets but showed an increased number of fecal pellets in the distal colon. In addition, the BE0623 yogurt (L-BE0623Y) group had the fewest fecal pellets in the distal colon. Regarding the serum lipid parameters, the LOP group had a high-density lipoprotein (HDL)/total cholesterol ratio that was 43% lower than that of a normal water group (NOR), but the outcome for the L-BE0623Y group was 27% lower than the NOR group. In a human study, 116 adults with IBS were sampled as subjects and fed 300 mL of yogurt per day for an eight week period. There was an IBS improvement in the L-BE0623Y and commercial yogurt (L-CY) groups, though flatulence, stool consistency and frequency of defecation outcomes were also noted. Specifically, the L-BE0623Y treatment group showed significant effects with regard to defecation duration and urgency after the consumption of the yogurt used in this study. These results suggest that the Bifidobacteria-enhanced yogurt has superior effects with regard to relieving loperamide-induced constipation in rats and that regular consumption of L-BE0623Y is effective to improve IBS in humans.

This study utilizes the IPA (Importance-Performance Analysis) method to assess the importance, possibility, and urgency of using blockchain technology for fisheries sectors and the related policies. Based on a field survey targeting experts and stakeholders in the fisheries and blockchain technology sectors, the following major results and corresponding implications are drawn. First of all, the respondents of our survey have an outlook that the introduction and utilization of blockchain will be required in four major parts. These parts include i) the seafood' information system managed by the government or public institutions, ii) traceability and certification process for domestic and foreign seafoods, iii) meeting the need of seafood safety from consumers, and iv) taking prompt actions to seafood safety related accidents. Next, the seafood information system managed by the government or public institutions has been limited in maintaining information consistency and continuity once the fisheries ministries and departments are integrated, closed or partially transferred. Thus, it is assessed that the technology will be able to improve consistency and continuity of the seafood information in case of applying blockchain to the seafood information management system. This result that blockchain is necessary for the seafood information system have a significant implication in Korea's seafood management which has been independently controlled until now. Lastly, the application of blockchain to seafood traceability and certification systems has the most well-known cases through international and domestic pilot projects, and the results of our survey reflect this reality. Our results contribute to showing an additonal characteristics of blockchain in the fisheries sector, resulting in the possiblity that blockchain can be used for taking swift steps in the event of seafood safety accidents and meeting the need of seafood consumers for safety.

Purpose: The Korean Triage and Acuity Scale (KTAS) is a tool used to classify the severity and urgency of emergency department (ED) patients, focusing on their symptoms. In consideration of the importance of the KTAS, a web-based learning program has emerged as a new mode of education; it enables ED triage nurses to access it anytime and anywhere, and according to their own learning abilities. This study aimed to develop a web-based KTAS learning program and evaluate its effects on self-efficacy and triage performance ability in ED nurses. Methods: A quasi-experimental design with a non-equivalent control group pretest-posttest was used. The conceptual framework was Bandura's self-efficacy theory. There were 30 participants in the experimental group and 29 in the control group. The experimental group attended an orientation and 4 sessions of a web-based KTAS learning program. The learning program lasted 280 minutes over five weeks, consisting of 40 minutes of orientation and four 60-minute sessions. Results: The scores of self-efficacy, triage performance ability in KTAS level, and chief complaints significantly increased in the experimental group compared to the control group. In addition, the numbers of under-triage in KTAS significantly decreased in the experimental group in comparison to the control group. Conclusion: The results suggest that the learning program was effective in improving ED nurses' level of self-efficacy and triage performance ability (KTAS level and KTAS chief complaint). Accordingly, the web-based KTAS learning program can be applied as an education intervention to improve ED nurses' triage skill.

In order to prevent interference and interference of the frequency, it is required to convert the regulatory standard into the center of the radiation power radiated to the actual public. Since the radiation power regulation is related to general radio management such as technical standards, permits, and inspections, it is gradually introduced in consideration of applicability and urgency, and the radiation power related laws of major countries And a method of controlling the output of the radio equipment such as measurement, inspection, and authentication. In Korea, the proportion of antenna power supply is high, and in Europe, radiation power is high. Since the number of radio stations will increase and diversify in the future, institutional improvement should be made so that it can be measured in parallel with the radiocommunication infrastructure of the space manager. In order to convert to the radiative power management system, the system for the related radio system needs(Technical standards, certification, inspection of radio stations, post-management, etc.) to be improved.

This study aims to propose educational information services for social science teachers by analyzing their information seeking behaviors. The author carried out in-depth interviews with thirteen social science teachers in Daejeon and analyzed them using an information seeking behavior model of Leckie, Pettigrew and Sylvain. The study results showed that information needs of social science teachers arise from extrinsic and intrinsic motivations according to their work roles and tasks. Also, the characteristics of information needs such as repeatability, predictability, urgency, and complexity appear to influence information seeking behaviors. The participants used various information sources including web, book, and interpersonal sources. Moreover, the study observed some factors that may influence perception toward information sources such as trustworthiness, information quality, packaging, prior success experience. Finally, the perception change and use frequency of information sources were also identified. Based on these findings, the author proposed information services for social science teachers including integrated information provision services, information literacy programs, networking services and readers advisory services.

Background: This study aimed to identify the role of dental hygienists in exchanges between North and South Korea to lower gaps in the level of dental healthcare between the two countries by conducting a Delphi survey with specialists and identifying alternative policies regarding the utilization of dental hygienists in such exchanges. Methods: Two Delphi surveys were conducted with the participation of nine specialists, and descriptive statistical analyses including mean and standard deviation were performed on the collected data. Results: Among methods of exchange and cooperation regarding oral healthcare under the current North Korean medical system, the issue considered most urgent was the "establishment of oral healthcare infrastructure." The most important short-term strategy was identified as the "selection and formation of partnerships in the field of inter-Korean oral health exchange and cooperation." The mid-term strategy was identified as the "establishment of cooperation in the dental industry, centered on educational cooperation projects." The long-term strategy included "joint R&D projects, oral health surveys, and business development." In order to determine how best to use dental hygienists during inter-Korean exchanges and cooperation, the respondents placed urgency on the "establishment of joint cooperation projects for oral health promotion and early examination and the treatment of dental diseases and planning of community research projects" and "the role of oral health education and media development for residents." Conclusion: Cooperation is necessary regarding the preparation of oral healthcare exchanges that aim to encourage unity between North and South Korea and reduce the gaps between the North and South regarding oral health conditions. Therefore, continuous and reasonable discussions and research are needed regarding the utilization of dental hygienists in such exchanges.

This research aims to identify and reveal the meaning of memes about COVID-19, and explain changes in meme content in regard to the information development of COVID-19 in Indonesia published by the mass media and online media. The data is sourced from memes that are shared on social media, especially WhatsApp groups in the period of January to June 2020. To reveal the meaning of memes, a semiotic analysis of Roland Barthes' model is used. Qualitative analysis is used to reveal the relationship between memes and the information development of COVID-19 in Indonesia. The results of the study show that meme content has shifted according to three stages of information development of COVID-19 in Indonesia published by the mass media and online media. When COVID-19 was not yet confirmed in Indonesia, meme content contained mostly humor that was not educative, moreover it seemed to underestimate the coronavirus. Meme content which is mostly humorous and pornographic occurred when COVID-19 was confirmed in Indonesia and during the lockdown policy. At last, as the government has begun to distribute social assistance, the meme content looks more critical. The results of this research emphasize the urgency of the mass media as a source of public information during the COVID-19 pandemic, become a reference for the community in making memes as a forum for expressing feelings and social criticism, and serve as a reference for the government to act and make the right decisions related to the pandemic that is endemic in their country.

Interstitial cystitis/bladder pain syndrome (IC/BPS) is a debilitating chronic disorder characterized by suprapubic pain and urinary symptoms such as urgency, nocturia, and frequency. The prevalence of IC/BPS is increasing as diagnostic criteria become more comprehensive. Conventional pharmacotherapy against IC/BPS has shown suboptimal effects, and consequently, patients with end-stage IC/BPS are subjected to surgery. The novel treatment strategies should have two main functions, anti-inflammatory action and the regeneration of glycosaminoglycan and urothelium layers. Stem cell therapy has been shown to have dual functions. Mesenchymal stem cells (MSCs) are a promising therapeutic option for IC/BPS, but they come with several shortcomings, such as immune activation and tumorigenicity. MSC-derived extracellular vesicles (MSC-EVs) hold numerous therapeutic cargos and are thus a viable cell-free therapeutic option. In this review, we provide a brief overview of IC/BPS pathophysiology and limitations of the MSC-based therapies. Then we provide a detailed explanation and discussion of therapeutic applications of EVs in IC/BPS as well as the possible mechanisms. We believe our review will give an insight into the strengths and drawbacks of EV-mediated IC/BPS therapy and will provide a basis for further development.
