  • Background Several bone grafting materials have been used in sinus augmentation procedures. Macroporous Biphasic Calcium Phosphate($MBCP^{TM}$) consists of the mixture of 60% HA and 40% ${\beta}-TCP$. Therefore, it can provide good scaffold for the new bone to grow owing to HA, in the other hand, it can have bioactivity for bone remodeling owing to ${\beta}-TCP$. The purpose of this study was to evaluate bone formation following maxillary sinus augmentation using $MBCP^{TM}$ by means of histologic analysis. Material and Method $MBCP^{TM}$ was placed as a primary bone substitute for maxillary sinus augmentation. Three patients were selected after evalaution of their medical dental examination. $MBCP^{TM}$ only, $MBCP^{TM}$ combined with Irradicated cancellous bone and $MBCP^{TM}$ combined with autogenous bone were used for each patient. After about eight months, bone biopsies were harvested for histologic evaluation and fixtures installed. Results Eight months after surgery we observed new vital bone surrounding $MBCP^{TM}$ particle and the amount of new bone was about 30% even though there were discrepancies between specimens. This case report documents that $MBCP^{TM}$ when used as a grafting material for sinus floor augmentation whether combined other bone graft material or not, may lead to the predictable results for dental implants on posterior maxillary area with insufficient vertical height for fixture installation.

  • The International Committee for Taxonomy of Viruses (ICTV), which was formed over 30 years ago, aims to develop a single, universal taxonomic scheme for all viruses or, in other words, "the classification of viruses and the assignment of names to taxa". Plant Virus taxonomy is in charge of Plant Virus Subcommittee, a substructure of the ICTV. The ICTV has been most successfully pursuing that aim and its mammoth 'Seventh Report' records details of the names it has collated and approved, and of the classification, it has devised. The current 7th ICTV report published in 2000 contains plant viruses of 951 species in 79 genera in 17 families, though 24 of the 79 genera are floating genera, that is, they are not included in any established families. Proposed name of new or existing viruses are vote for the accepted taxonomic proposals by ICTV Executive Committee meeting. The approved results have been published as the ICTV reports providing standard names and taxa of viruses all over the world. A number of new plant viruses have been identified or reclassified in the genus or species level, and new genera and families have been proposed.(중략)

  • Objectives: Chronic fatigue syndrome (CFS) is a debilitating illness impairing seriously quality of life, while CFS would be an optimized target disorder of Korean medicine. This study aims to present the recent information especially in aspect of medical policy and new diagnosis criteria for CFS. Methods: The literature survey was conducted using the terms of "chronic fatigue syndrome", "myalgic encephalomyelitis" and "fibromyalgia" in PubMed database and Google database in its entirety from January 2011 to February 2019. The in-depth review was made focusing on the changes in policy and medical perspective for CFS. Results: Recently large medical attentions and researches for CFS have been existed worldwide. By supporting of USA government, IOM made a report which leaded to a turning point in clinical practices and research in 2015. This report recommended a new name of CFS to systemic exertion intolerance disease (SEID), and new diagnostic criteria focusing on post-exertional malaise, unrefreshing sleep, cognitive impairment and orthostatic intolerance. The medical perspective also was changed into "a serious, chronic, complex, systemic disease" from a psychological-like disorder, and then UAS and EU governments sharply increased the research grants. Conclusions: This study provided practitioners in Korean medicine (KM) a core information about the recent changes in CFS-related perspectives. This review would be helpful for KM-derived researches or therapeutics development for CFS.

  • Earlier taxonomic studies of Korean Scutellaria reported a new record of Scutellaria hastifolia L. in Korea based on three herbarium sheets. During a reexamination of these specimens, we found that the leaf characters of these specimens differ from those in the type specimen of S. hastifolia. Based on a literature survey and confirmation of the type specimen, the specimens identified as S. hastifolia thus far were a misidentification of S. barbata D. Don. S. hastifolia is clearly different from S. barbata by single conspicuous teeth on both sides of the leaf margins and larger leaves. In addition to the distribution sites of the three specimens used in the previous study, a distribution site of the S. barbata was newly found in the southern part of Korea. In this study, we report a new distribution of S. barbata in Korea, correct a previous report of S. hastifolia, describe the morphological characters of S. barbata, and suggest a taxonomic key to Korean Scutellaria including S. barbata.

  • Two species of hippolytid shrimps, Eualus kuratai Miyake and Hayashi, 1967 and Heptacarpus igarashii Hayashi and Chiba, 1989, were collected at a sea cucumber farm from the East Sea. These species are described and illustrated for the first time in Korea. Eualus kuratai is closely related to E. middendorffi; however, it lacks a dorsomedian spine on the fourth and fifth abdominal somites. Heptacarpus igarashii can be easily distinguished from other Korean Heptacarpus species due to its short rostrum that lacks ventral teeth on margin. This report extends the previously known ranges from Japan and Korea. In Korea, both genera, Eualus and Heptacarpus, have seven species according to the present report, respectively; moreover, hippolytid shrimps now consist of 31 species of nine genera.

  • This study integrates Rivet and Retrieved Augmented Generation (RAG) technologies to enhance automated report generation, addressing the challenges of large-scale data management. We introduce novel algorithms, such as Dynamic Data Synchronization and Contextual Compression, expected to improve report generation speed by 40% and accuracy by 25%. The application, demonstrated through a model corporate entity, "Company L," shows how such integrations can enhance business intelligence. Empirical validations planned will utilize metrics like precision, recall, and BLEU to substantiate the improvements, setting new benchmarks for the industry. This research highlights the potential of advanced technologies in transforming corporate data processes.
