  • Amblovenatum immersum (Blume) Mazumdar (Thelypteridaceae) is newly recorded in Vietnam. It is similar to A. terminans (Panigrahi) J. P. Roux in its woody rhizome and cristate spores but differs in terms of its plant size, lobed pinnae, lobed segments, veinlets, sori and indusia. It was previously found to exist in China, India, Indonesia, Malaysia, Myanmar, Philippines, Sri Lanka, and Thailand as well as in east Africa, tropical America, northern Australia and Micronesia. The present study provides a detailed description, photos, and line drawing of the species. Furthermore, a comparison of the diagnostic characters with the closely related species in Vietnam A. terminans is provided.

  • Ginseng is described as the "King of all herbs, "Man-root" or "Root of heaven" and regarded as the most powerful herbal remedy, particularly grown in Korea, China, Japan, Vietnam, and North America. It has been in existence for a long time. The most demanded herbal cure, Ginseng, principally the root, has long been employed in traditional Asian medicine. The extent of availability of bioactive combinations and their impact on the body differs between American and Asian ginseng. Asian ginseng, also known as Panax ginseng, has a more calming influence and is more advantageous than American ginseng, such as Panax quinquefolius. The pharmaceutical aspect of development and extraction with diverse morphological properties is examined. Saponins, glycosides, carbohydrates, polyacetylenes, amino acids, vitamins, volatile oil, enzymes are all present in the Phyto-content of Ginseng. Ginsenosides are saponins that are constituents of the triterpenoid dammarane and have anticancer, anti-cardiovascular, anti-microbial, anti-obesity, anti-inflammatory, and antioxidant properties. Ginseng, in particular, has the possibility to help with microbial invasion, inflammatory processes, oxidative stress, and diabetes. It developed nanoparticles and nanocomposite film technologies as novel drug delivery platforms for cancer, inflammation, and neurological illnesses. Furthermore, it offers a range of applications that will be vital for future growth.

  • Recently, the explosive increase of carbapenemase-producing Enterobacterales (CPE) in the worldwide poses a serious threat. The purpose of this study is to investigate epidemiology, detection, and treatment of CPE. Three main carbapenemase are reported worldwide, which were KPC, NDM, and OXA-48-like. KPC type are mostly found in USA, China, Europe, and Latin America. NDM type are mostly found in South Asia. OXA-48-like are often seen in the Mediterranean and Northern Africa. In Korea, CPE have increased explosively since 2015. In 2021, 18,099 CPE were isolated, which were Klebsiella pneumoniae, Escherichia coli, and Enterobacter cloacae in order. The CPE genotype was distributed with KPC, NDM, OXA type in order. Phenotypic detection methods include carbapenemase production tests (CPT) and differential tests of CPE. CPTs include modified Hodge test, modified carbapenem inactivation method (mCIM), Carba NP test, among which mCIM is the most widely used due to easy accessibility and accuracy. A lot of genotypic methods are being done for quick results, and commercialized kits using multiplex real-time PCR and microarray are widely used. Colistin and tigecycline are used as the first line of CPE treatment and are used in combination with second line drugs such as meropenem and fosfomycin.

  • Purpose: The purpose of this study is to extend the knowledge about two volumes of Kanho Kyokwaseo (Textbook of Nursing) published in 1908 and 1910. Methods: The books were investigated from the first to the last pages and compared with other textbooks published during the same period. Results: The origin of these books was from Hubinyaoshu (Manual of Nursing) published in China in 1904. They were translated by Edmunds, a missionary nurse from America, and Chang Chai-Sun, a teacher at the first nursing school in Korea, along with inspection by Korean teachers who were fluent in English. Kanho Kyokwaseo are user-friendly textbooks in that they are written mainly in Hangul; Chinese and English are added in cases of explicating western scientific terminology and medical terminology, with notes at the top, on the left, and on the right of the page. The contents emphasize reporting and submission to supervisors and doctors. Surgical nursing occupies the largest chapter. Disinfection and hygiene, the advantages of western modern medicine, are dealt with repeatedly and importantly. Conclusion: Kanho Kyokwaseo was widely used as the first and only nursing textbook published before Japanese occupation and as a publication having upgraded the level of textbooks.

  • Neosiphonia japonica is a rhodomelacean red alga that occurs in Korea, Japan, China, far-east Russia, northwest America, and New Zealand. Although it is distinguished by a bush-like habit having four pericental cells with cortication and numerous branches on axes, the taxonomy of N. japonica is still problematic. To investigate the taxonomy and phylogeny of the species, we analyzed rbcL and phycoerythrin (cpeA/B) genes from 19 samples of N. japonica and putative relatives. Phylogenetic trees from both genes show that N. japonica from Korea, Japan, New Zealand, and USA is clearly separated from N. decumbens, N. harlandii, and N. flavimarina from the Pacific Ocean. Instead, N. harveyi from the Atlantic Ocean was more related to N. flavimarina than to N. japonica. This result supports morphological and distributional differences between N. japonica and N. harveyi. However, the close relationship between these species suggests that they might have a recent most common ancestor. This is the second report to use the cpeA/B gene for evaluating species diversity in the Rhodophytes.

  • The purpose of this research is to study and understand the foreign tourist market's preferences and purchasing behaviors of Korean. Especially this study seeks to achieve this purpose by classifying the preferences and purchasing behaviors by nationality into general product. To confirm this research objective, data was collected with questionnaire method along with literature research. Targeting tourists from Japan, America, and China, the questionnaire survey examined their preferences for general color and design as well as the differences and commonality of their purchasing behaviors. As a result of examining foreign tourists' awareness of traditional tourist souvenir, the significant difference was shown by each country. Also, as for the purchasing behavior and preference for foreign tourists' traditional tourist souvenir, results indicated that Americans consider the element of geographical significance and value more than other groups of tourists. Resultantly, people have a different taste of souvenir in color, design, transform and so on by nationality.

  • Even though Korea has very low possibility that a big earthquake occurs like in Japan, China, Taiwan and United States of America, because it is located on the interior of Eurasian Plate, the earthquake which was struck northeast Japan in March 11th, 2011 gave a big shock to Korean. And small-medium earthquakes have been observed 922 times in Korea since 1978 when an earthquake hit Hong-seong and a seismographic station started observation. Moreover, the number of quakes has been on the increase. In case a big earthquake occurs like in northeast Japan, it would be a terrible disaster for Korean power utilities and brings mega effects on Korean society and economy. So it is necessary to apply anti-earthquake design for new power facilities and to reinforce existing facilities. Therefore, this paper would present anti-earthquake design for transmission line and substation and reinforcement measures for existing facilities.

  • Natural ecosystem is an essential part to connect with the plan for biodiversity conservation in response strategy against climate change. For connecting biodiversity conservation with climate change strategy, Europe, America, Japan, and China are making an effort to discuss protection necessity through national biodiversity valuation but precedent studies lack in Korea. In this study, we made biodiversity maps representing biodiversity distribution range using species richness in National Forest Inventory (NFI) and Forest Description data. Using regression tree algorithm, we divided various classes by decision rule and constructed biodiversity maps, which has accuracy level of over 70%. Therefore, the biodiversity maps produced in this study can be used as base information for decision makers and plan for conservation of biodiversity & continuous management. Furthermore, this study can suggest a strategy for increasing efficiency of forest information in national level.
