The mobile agent is receiving the attention as new technique to retrieve and to share the distributed contents on web-based educational systems. The retrieval using mobile agent uses the method that delivers the agent to accomplish a search in direct server in substitute for it is transmitted a many contents to accomplish an efficient search. This study proposed the model of retrieval system that shares and searches the distributed educational contents of the bulletin board and newsgroup by using the mobile agent. In order to evaluate the efficiencies of the system that is proposed, we did the comparison test on the search model of existing and proposing system. By a test result, we confirmed network traffics of proposed system are diminished. Moreover we gave proof the fact that the optimum search time of the mobile agent-based system is shortened.

Today information is important for man and total fields. Science field is not exception. Currently information age things of information is only useful for man and total industry. So bioinformation is necessary of biodiversity in broadly wide and detailed information. Among information, bioinformation of biodiversity is important and utilization of living things. Among them, the mushroom(higher fungi) are an important part in ecosystem as a decomposer responsible for recycling materials. Many living things today, however, have endangered by environmental pollution and ecological destruction. The higher fungi also are not exception. Mushroom has been used for food sources, pharmacy and forests resources from ancient times. Among biodiversity, database of mushroom is very necessary for university, institute and industry. This DB contains four items of native mushroom(higher fungi) from Korea. first item contain species, genus, family, order class, ad division according to the classification. Second item contain pharmaceutical purpose, food source, culture, toxic, anti-cancer of the application. Third item contain symbiosis, rotten trees of the ecological resources. Fourth item contain geographical distribution and illustrated literature. Information system is also available using KRISTAL II for searches on the WEB in URL http://ruby. kisti. re. kr/∼mushroom.

Background: There is evidence of destructive effects of oxytocin use during labor on neurodevelopment. Purpose: This meta-analysis pooled all observational studies to determine the association between labor induction and the risk of attention-deficit/hyperactivity disorder (ADHD) among children. Methods: All observational studies (case-control and cohort) were reviewed until September 2020 after searches of the PubMed, Scopus, and Web of Science databases, the gray literature, and conference proceedings. The pooled odds ratios (ORs), relative ratios (RRs), and 95% confidence intervals (CI (swere calculated as random effect estimates of association among studies. Results: All observational studies were reviewed, including 4 cohort studies including 2,885,743 participants and 3 case-control studies including 51,135 participants (10,961 with ADHD and 40,174 in control groups) with a sample size of 2,936,878 participants. The pooled estimates of OR and RR did not indicate a significant association between labor induction and ADHD among children (OR, 1.13; 95% CI, 0.90-1.35) and (RR, 1.10; 95% CI, 0.96-1.24). Conclusions: The findings showed that labor induction is not associated with an increased risk of ADHD among children. However, more studies are needed to investigate the relationship between labor induction and ADHD.

Dental implants are popular for dental rehabilitation after tooth loss. The goal of this systematic review was to assess bone changes around bone-level and tissue-level implants and the possible causes. Electronic searches of PubMed, Google Scholar, Scopus, and Web of Science, and a hand search limited to English language clinical trials were performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines up to September 2020. Studies that stated the type of implants used, and that reported bone-level changes after insertion met the inclusion criteria. The risk of bias was also evaluated. A total of 38 studies were included. Eighteen studies only used bone-level implants, 10 utilized tissue-level designs and 10 observed bone-level changes in both types of implants. Based on bias assessments, evaluating the risk of bias was not applicable in most studies. There are vast differences in methodologies, follow-ups, and multifactorial characteristics of bone loss around implants, which makes direct comparison impossible. Therefore, further well-structured studies are needed.

This study aims to examine the relationship between customer satisfaction and revisit intention according to the selected attributes of dessert cafes in Korea. Additionally, we would like to provide useful data to maintain a continuous competitive advantage by comprehensively reviewing the effective operation of dessert cafes and strategic plans and methods to identify customer needs in the rapidly spreading competitive environment of the domestic dessert restaurant industry in Korea. A qualitative analysis method was applied through a literature review on satisfaction and revisit according to the selected attributes of dessert cafes, and data using theoretical backgrounds obtained through web searches and existing cases. As a result, dessert quality and convenience showed inconsistent results, and coffee quality was found to have a statistically significant positive (+) effect in various data. Moreover, various attributes such as service, image, price, diversity, and service had a significantly positive (+) effect, and satisfaction with dessert cafes also had a significantly positive (+) effect on revisit intention. In conclusion, dessert cafe managers should develop various desires that reflect consumers' tastes and are competitive so that customers can revisit dessert cafes, which requires more in-depth analysis by obtaining a more systematic sample group in the future.

Purpose - This study aims to predict the future market and draw policy implications by analyzing the trend of outsourcing housework through the food subscription service. Research design, data, and methodology - Content analysis was conducted on the consumption value emphasized in advertisements by item targeting food subscription service advertisements. Advertisements used as research data were extracted via keyword searches on Google web pages. A total of 30 advertisements selected were used for the final analysis. Result -The consumption values emphasized in the advertisements for staple foods, refreshments, and special foods were analyzed by considering the following factors: price, convenience, health, and pleasure. Convenience and health were emphasized in the staple foods, and price and pleasure were emphasized in the snacks. In the case of special foods, convenience and pleasure appeared together with a focus on health. Conclusion - Based on the trend of food subscription services, the implications for the market and policies for outsourcing housework through home meal replacement can be presented. Considering that the consumption value of a food subscription service is differentiated by item, it is necessary to formulate a plan to develop the market and policies related to outsourcing housework.

Purpose: This scoping review identified scientific evidence on basic human needs (BHNs) in the elderly receiving palliative care. Methods: Systematic searches were conducted using six electronic databases (PubMed, CINAHL, Scopus, Lilacs, IBECS, and Web of Science). The initial search resulted in 1,227 articles, of which 104 were identified as potentially relevant. Fifty-three articles that met the inclusion criteria were identified and included in the final analysis. Results: Using the three hierarchical dimensions of the BHN model, 17 needs were organised, with five in the psychobiological dimension, 10 in the psychosocial dimension, and two in the psychospiritual dimension. These needs reflect the importance of care with dignity and relief from suffering for the elderly in palliative care. Conclusion: Recognising impaired BHNs in elderly people receiving palliative care will contribute to better care plans for the elderly, considering the multiple bio-psycho-social-spiritual dimensions of BHNs. This review points to a predominance of psychosocial needs.

This systematic review aimed to investigate whether minimally invasive root canal preparation ensures higher fracture resistance compared to conventional root canal preparation in endodontically treated teeth (ETT). A comprehensive search strategy was conducted on the "PubMed, Web of Science, and Scopus" databases, alongside reference and hand searches, with language restrictions applied. Two independent reviews selected pertinent laboratory studies that explored the effect of minimally invasive root canal preparation on fracture resistance, in comparison to larger preparation counterparts. The quality of the studies was assessed, and the risk of bias was categorized as low, moderate, or high. The electronic search yielded a total of 1,767 articles. After applying eligibility criteria, 8 studies were included. Given the low methodological quality of these studies and the large variability of fracture resistance values, the impact of reduced apical size and/or taper on the fracture resistance of the ETT can be considered uncertain. This systematic review could not reveal sufficient evidence regarding the effect of minimally invasive preparation on increasing fracture resistance of ETT, primarily due to the inherent limitations of the studies and the moderate risk of bias.
