Prebiotics are defined as substrates that are selectively utilized by host microorganisms conferring various health benefits. Current prebiotic researches not only focus on non-digestible oligosaccharides, but also extend to polyphenols and peptides. However, the extended scope of prebiotic research pertains its original purposes: promotion of beneficial bacteria in host guts and production of valuable metabolites. Maintenance of optimal gut microflora plays a key role in host health care benefits including anti-cancer activity, immune response modulation, blood lipid level reduction, increased mineral absorption, and weight loss. With increasing probiotics markets, prebiotics have also received much attention in functional food markets. Hence, many global food companies tempt to develop new prebiotics applicable for preventing human diseases as well as modulating immune system. In this review, we discuss current status of prebiotics research, market progress, and future perspectives of prebiotics.

Phytobiotics, also known as phytochemicals or phytogenics, have a wide variety of biological activities and have recently emerged as alternatives to synthetic antibiotic growth promoters. Numerous studies have reported the growth-promoting effects of phytobiotics in chickens, but their precise mechanism of action is yet to be elucidated. Phytobiotics are traditionally known for their antioxidant activity. However, extensive investigations have shown that these compounds also have anti-inflammatory, antimicrobial, and transcription-modulating effects. Phytobiotics are non-nutritive constituents, and their bioavailability is low. Nonetheless, their beneficial effects have been observed in several tissues or organs. The health benefits of the ingestion of phytobiotics are attributed to their antioxidant activity. However, several studies have revealed that not all these benefits could be explained by the antioxidant effects alone. In this review, I focused on the bioavailability of phytobiotics and the possible mechanisms underlying their overall effects on intestinal barrier functions, inflammatory status, gut microbiota, systemic inflammation, and metabolism, rather than the specific effects of each compound. I also discuss the possible mechanisms by which phytobiotics contribute to growth promotion in chickens.

Background: Cancer is a leading cause of death in Korea. To prevent cancer, it is essential to facilitate and promote appropriate cancer screening behavior in the adult population. The aim of this study was to examine health beliefs related to cancer screening intentions using the Health Belief Model (HBM). Materials and Methods: The research participants comprised 275 male health and safety managers at commercial companies in Korea. The self-administered survey explored demographic characteristics, cancer-related factors, beliefs about cancer/cancer screening (BCCS) (vulnerability to cancer, severity of cancer, benefits of screening, and barriers to screening), and cancer screening intention. Multivariate logistic regression analyses were used to identify factors associated with an intention to be screened for cancer. Results: Perceived health status and need for cancer prevention education were major factors associated with BCCS. Poorer health status was associated with greater perceived vulnerability, a perception of fewer benefits, and more barriers (p<0.05). A perceived greater need for cancer prevention education was associated with a higher perceived severity of cancer and more perceived barriers to screening (p<0.05). Marital status, cancer screening experience, and perceived vulnerability to cancer were significant influences on the cancer screening intention (p<0.05). Participants who had undergone cancer screening in the past 2 years were more likely to intend to be screened for cancer than were those who had not been screened; this was true across all degrees of intention and all types of cancer (p<0.01). Hesitant people considered themselves less vulnerable to gastric, lung, and liver cancer than did the poeple who intended to undergo cancer screening (p<0.05). Conclusions: Based on our findings, we recommend that workplace cancer prevention programs attempt to increase awareness about vulnerability to cancer among workers who hesitate to undergo cancer screening.

Background: Legal regulations and fees have been established in Korea to provide visiting oral health care services to individuals with long-term care insurance (LTCI). However, beneficiaries of this service are very limited. Therefore, to improve the Korean system we propose a comparative analysis with the Japanese system. Methods: This study is a descriptive analysis based on secondary data, such as statistics, laws, and service record forms from Korea and Japan. The most recent institutional documents were obtained through a Google search. The variables investigated were financial resources of LTCI, co-payment structure, monthly limit of LTCI benefits, care levels of LTCI, service providers, service costs, contents of service, and the number of cases of service. Results: In both Korea and Japan, LTCI is financed through a combination of taxes and insurance premiums. However, the monthly limit for receiving LTCI services in Japan is about 2.4 times higher than in Korea. Visiting medical and dental treatment is also possible in Japan. Furthermore, nursing staff can provide daily oral health care services according to dental hygienists' instruction unlike Korea. Oral health care services in Korea are focused on oral hygiene and prevention of oral diseases, while Japan additionally provides oral function screening, patient education for oral health management, and training for nursing staff to enhance oral function, eating, and swallowing of the patients. Conclusion: We concluded that the possibility of visiting dental treatment, differences in monthly limit of LTCI benefits, oral function assessment and guidance, as well as collaboration with other healthcare professionals contributed to the difference in the frequency of utilization of visiting oral health care services between Korea and Japan.

Objectives: The demand for dental care is expected to increase as the population ages. This study aimed to predict the utilization of dental implant care following the expansion of national health insurance benefits for dental implants. Methods: Multiple linear regression analysis was performed on HIRA big data open portal data and DNN-based artificial intelligence models to forecast the utilization of dental care in relation to the national health insurance coverage for dental implants. Results: National health insurance coverage of dental implants was found to be associated with the number of patients using dental implant services and demonstrated a statistical significance. The dental implant services utilization increased with the increased dental implant health insurance benefits for the elderly population, increased mean by region, increased number of dental institutions by region, and increased health insurance coverage rate for dental implants. However, the dental implant services utilization decreased with the increased number of older people living alone and increased size of dental institutions. Conclusions: With the expansion of the national health insurance coverage for dental implants, it is predicted that the utilization of dental implant medical services will increase in the future.

African Americans in the United States suffer from many health disparities such as obesity, diabetes or hypertension. Lifestyle factors including diet and physical activity play an important role in prevention of these health conditions. The purpose of this research project was to assess beliefs, barriers and self-efficacy of eating a healthy diet and self efficacy of shopping for foods such as whole grains or foods designated as low fat or low sodium. Additionally, the objective was to assess beliefs about healthfulness, appropriate consumption, and protective aspect of specific foods including fruits, vegetables, and whole grains. The assessment was done using a survey instrument developed for this study. Data collection took place at two church locations. Data were obtained from 57 African Americans, mean age 50 years old (SD 12.70) completed the survey. The majority of respondents (58.1%) were females and most (75%) had at least some college education. Generally, benefits of eating healthy foods received considerably higher scores compared to barriers of eating healthy. A belief that healthy foods would help to take care of one's body received the highest mean score while a belief that healthy foods are too expensive had the highest score from all barriers. The results showed high self-efficacy of eating and purchasing healthy foods, high awareness of knowledge regarding foods associated with disease prevention but low awareness of recommendations for fruits and vegetables. The high scores for benefits, self-efficacy and knowledge regarding eating healthy foods did not translate into the perception of intake of such foods. Most participants believed that they do not eat enough of healthy foods. Interventions design to help African Americans make dietary changes should be culturally relevant and should involved working on a community level utilizing messages that are familiar and relevant to African Americans.

The nail service field, which has emerged as a new trend in the beauty industry, is showing rapid growth compared to other beauty fields. As nail beauty services become more common and popular, studies on related fields are also actively progressing, but most of the research has been focused on changes on self-esteem. In addition, most of the preceding studies are centered on female customers, thus, there is little data on male customers that are increasing recently. This research aims to provide customized marketing data to the nail beauty service industry by analyzing the psychological characteristics of the customers and their motives by selecting self-esteem and confidence as factors. First, the customers' confidence and self-esteem were classified into a group with high and low confidence and self-esteem, and as a result of analyzing the difference in service pursuit benefits and revisit intentions, there were significant differences in mood change, professionalism, health hygiene, aesthetics, and revisit. Second, as a result of analyzing the effect of the service pursuit benefits of male and female customers on the revisit intention, it was found that only health and hygiene had a significant effect on the revisit intention. Female customers also had a significant influence on their revisit intention, which is judged to have a significant effect on male customers' revisit intention because most of the main management is cuticle cleaning, callus management, and problematic nails.
