  • Members of the genus Asarum of Korea were reviewed taxonomically, and classified into seven species. Among them, four species - A. koreanum, A. maculatum, A. patens and A. versicolor - were recorded as Korean endemics. The most valuable taxonomic characters in identifying the Asarum taxa were shape, size and color of the calyx tube and lobe. In addition, the presence of white spots on the adaxial surface, size and color of leaf, presence of trichome, shape and size of the stylar protuberance and thickness of the calyx lobe were also important characters. Keys to the species including descriptions and figures of floral structures of each taxon were provided here for the accurate identification of each species.

  • We would like to find out how restaurant start-up education affects restaurant start-ups. Recently, as low barriers to entry and endemics are approaching, more and more people want to start a restaurant business. However, while the market size of restaurant start-ups increases due to the high youth unemployment rate and changes in the social population structure, the probability of failure of start-ups is increasing due to the high competition rate. Therefore, this study aims to examine whether restaurant start-up education affects restaurant start-ups through entrepreneurship. This study conducted a survey on prospective start-ups. After that, demographic analysis and multiple regression analysis were performed using the SPSS 23.0 program. As a result, it was found that entrepreneurship had an effect on restaurant start-ups. However, in future studies, more research is needed on the direction of improving and developing restaurant start-up education.

  • The five species of the genus Microphysogobio in Korea are reviewed with the keys to species and their illustrations: M. longidorsalis, M. jeoni sp. nov., M. koreeneis, M. yaluensis, and M. rapidus. Microphysogobio tungtingensis uchidai was treated as a junior synonym of M. yaluensis based on having the distinct papillae of upper lip and the color pattern on body sides by the examination of the type specimens. Microphysogobio jeoni is described as a new species from the specimens collected in the Naktong River, Han River and Keum River, Korea. it is well distinguished from the related species by the slender body, undeveloped papillae of upper lip and unspotted fins. Microphysogobio yaluensis was showed the clinal variations in the number of lateral line scales and vertebrae among the populations in the western drainages of Korea. It is remarked biogeographically that the five species of Microphysogobio are all endemics to Korea with the restricted ranges.

The field works was done for about twenty times in nine major areas from March, 1995 to Octover, 1996. The total number of vascular plants In this area were summarized as 103 families, 312 genera, 493 species and 564 kinds. The fourteen kinds of artificially planted, ten kinds of Korean endemics and twenty-nine kinds of Korean rare and endangered species in the area were revised and compiled in the list. The flora of the area were categorized into the South-coast put of the Korean Region, where the species such as Platycarya strobilacea, Quercug serrata, Eutya japonica, Camellia japonica, Trachelosperm urn asia talcum vu . in termedium, Quercus acu tissima were roles as major floristic components in the Korean Region and endemized in the south-cosat part of Korea. The natural communities such as Pinus thunbergii Community, Quercus mongolica community, Cupinus laxiflora Community, Wistria floribunda Community and swamp vegetation in Bukmun area as well as upland grassland at the summit of Kodangpong were represented for their floristic values in the area. The thirty kinds of medichinal plant, fifteen kinds of ornamental plants and thirteen kinds of edible plants are faced potentially in endangered from the outrageous collections by the local peoples. The action plan for the conservation management of the area which enables sustainable use by the local peoples must have established in the near feature.

  • Fish fauna of mountain streams in the Jirisan National Park area of S. Korea (total area: 440.45 $\textrm{km}^2$, height: 1,915 m) was investigated at 33 sites from May 1997 to September 1999. A total of 4,670 individuals of fishes were collected and classified into 30 species and 12 families. Zacco temmincki (relative abundance (RA), 63.9%) was found to be the most abundant inhabitant. Subdominant species were Pungtungia hem (RA 6.2%), Zacco platypus (RA 6.1 %) and Coreoleusiscus splendidus (RA 4.8%). Among the total species, 13 species were identified as the Korean endemic species (7 families, 17.2% of 802 individuals). Dominant Korean endemic species was C. splendidus (relative abundance endemics (RAE), 27.8%). Superiors were Coreoperca heizi (RAE 21.8%) and Liobagrus mediadiposalis (RAE 19.8%). One exotic species (Oncorhynchus mykiss, a site and 5 ind.) and translated species (Hypmesus niponensis, two sites and 174 ind.) were collected in this survey. The proportion of Korean endemic species in the park (43.3%) was higher than the average of Korean Peninsular (25.9%). From this study, we conclude that the Jirisan National Park area in Korea would be very important for fish diversity and conservation, especially for the Korean endemic and endangered species.

  • The taxonomic revision of the family Clupeidae was conducted based on the specimens collected from the coasts of Korean Peninsula from 1990 to 1995. Eleven species belonging to ten genera are reviewed and provisional keys to species and genera are provided with synonyms and their distributions. Ilisha elongata (Bennett, 1830) is proposed as a replacement name for Pristigaster chinensis, Etrumeus teres (De Kay, 1842) for E. micropus, Spratelloides gracilis (Temminck et Schlegel, 1846) for S. japonicus, Sardinella jussieu (Valenciennes, 1847) for S. immaculata, Sardinella zunasi (Bleeker, 1854) for Harengula zunasi, and Tenualosa reeuesii (Richardson, 1846) for Macrura reeuesii respectively. Most species of the family Clupeidae in Korea are shared with Chinese and Japanese faunas including tropical and temperature species without endemics.

  • The flora of vascular plants and the present vegetation status of Minjujisan and its adjacent regions were investigated from 2000 to 2004, total 27 times. The plant taxa of these areas consist of 764 taxa totally; 172 families, 397 genera, 631 species, 3 subspecies, 105 varieties and 25 forms. There were many useful plants such as 35 taxa of Korean endemics, 12 taxa of rare and endangered plants, and 101 taxa of specially designated plants which were determined by the Ministry of Environment. Furthermore, 46 taxa of naturalized alien plants were also investigated in the boundary of developing areas. The vegetation status of investigated area was comparatively well conserved, but the degree of damage was increasing rapidly by development, deforestation, and tramp which were induced by the disturbances of human beings. Therefore, more active conservation strategies such as expanded designation of conservation area. should be established, and carried out continuously based on the results of long-term monitoring studies.

  • The saga of Megascolides orthostichon (Schmarda, 1861)-the first native worm described from Australasia-continues as its type-locality is unequivocally returned from Hobart, Tasmania to Mt Wellington, Auckland where a brief survey failed to unearth it. Since it has not been seen for 150 yrs, it may qualify under NZTCS or IUCN classification as 'Nationally Critical' if not 'Extinct'. New reports are for exotic Megascolecidae Anisochaeta kiwi sp. nov. and A. kiwi mihi sub-sp. nov. plus addition to the NZ faunal list of Australian Anisochaeta macleayi (Fletcher, 1889) that, due to its wide distribution in Australia and now New Zealand, may be a candidate model-species suitably resilient for eco-toxicological culture and monitoring. For holarctic Lumbricidae, new records are of Dendrobaena attemsi (Michaelsen, 1903) and the Murchieona muldali (Omodeo, 1956) morph or subspecies of M. minuscula (Rosa, 1906), neither lumbricid previously uncovered in Asia/Australasia. Also found for the first time outside its East Asian homeland is Eisenia japonica (Michaelsen, 1892) (which is compared to Japanese E. japonica hiramoto sub-sp. nov. and to E. anzac Blakemore, 2011). Records of these exotics plus recent new native species described by the author-including two, Rhododrilus mangamingi and Deinodrilus orcus spp. novae, herein-raise the numbers of megadriles known from New Zealand to 228 (sub-)species in five families. Preliminary mtDNA COI sequence barcodes are presented. Genus Tokea Benham, 1904 is revived on its lack of dorsal pores, losing or gaining some species with Megascolides M'Coy, 1878. An updated checklist of all 228 New Zealand taxa is appended.
