  • Two species of marine algae, Fauchea spinulosa Okamura et Segawa (Rhodymeniaceae, Rhodophyceae) and Stictyosiphon soriferus (Reinke) Rosenvinge (Chodariaceae, Phaeophyceae) were newly collected from the southern coast and Cheju Island of Korea. Fauchea spinulosa was collected from subtidal zone in the insular region of the southern coast. Plants were erect from the discoidal holdfast with short stipe, pinkish to deep red, cartilageneous, dichotomously and flabellately branched, and 10-15 cm high, 5-15 mm broad. Tetrasporangia are cruciately divided and nemathecia occurred on a side of the branches. Cystocarps were mostly coronate in marginal area and spermatangia were scattered on both sides of branches. Stictyosiphon soriferus commonly occurs on muddy and sandy intertidal flat of Namhaedo located on the southern coast. Plants are epilithic, light brown, terete, 3-5 cm high, and branched heavily in irregular or alternate manner, arising from a small holdfast with rhizoidal clumps. Plurilocular sporangia were scattered in patches and slightly swollen above the cortex of the whole filament. Unilocular sporangia were not found.

  • The genus Petroderma never been reported from the coast of Korea. In this study, our collection from Chaeseokang is matched with P. maculiforme morphologically. Petroderma maculiforme is characterized by having small irregular light to dark brown crusts, a basal layer of irregularly shaped cells giving rise to erect parallel filaments which easily separate with pressure, single chromatophore per cell, small spherical to cylindrical unilocular sporangia in a terminal position, and plurilocular sporangia narrower than erect filaments or wider and shorter than erect filaments in a terminal position. In addition, Hineksia sordida was also collected from Korea. It is mostly epiphytic and characterized by uniseriate filamentous thalli forming loose tangled masses, sparse and spiral branching, some long lateral branches, rhizoids occurring throughout the plant, plurilocular and unilocular sporangia scattered on separate plants. Our molecular analyses based on the rbcL gene reveal that our samples of P. maculiforme and H. sordida are nested within the clades of Petroderma and Hincksia, respectively. Therefore P. maculiforme and H. sordida are reported as new records from Korea based on morphological and molecular analyses.

  • Three species of micromoths, Acria emarginella Donovan, 1806 (Peleopodidae), Yponomeuta cinefactus Meyrick, 1935 (Yponomeutidae) and Depressaria leucocephala Snellen, 1884 (Depressariidae) are reported for the first time from Korea. These species were collected at their larval stage on the host plants, and reared until their emergence. Images of larvae, pupae, and adults of all species are given, and the male or female genitalia are illustrated.

  • In this article, the author introduces the paradigm shift in archival studies that occurs in north America. Although the dominant paradigm in the archival studies-the positivism paradigm-greatly contributed to build modern archives in Europe and north America, during last decades, new ideas and technologies led the archival communities to re-identify their social roles and powers and to adopt new values of archives and archivist. This essay argues that this changes is essential to our future and we understand the nature of the changes from the broader interdisciplinary perspective of archives studies, information studies, and history.

  • Fieldwork in Lao PDR during 2007-2008 resulted in the discovery of 15 unrecorded fern species among the flora of Lao PDR. All have been identified in other countries in southeastern Asia, as well as from other tropical areas. The species are as follows: Asplenicaceae (Asplenium delavayi, A. rockier), Athyriaceae (Anisocampium cuspidatum), Dennstaedtiaceae (Microlepia hookeriana, Pteridium revolutum), Dryopteridaceae (Didymochlaena truncatula, Dryopteris cochleata, Polystichum biaristatum, P. lindsaefolium), Gleicheniaceae (Dicranopteris curranii), Hypodematiaceae (Hypodematium crenatum), Lindsaeaceae (Lindsaea heterophylla), Pteridaceae (Pteris decrescens), Polypodiaceae (Pyrrosia nummularifolia) and Thelypteridaceae (Cyclosorus dentatus).

  • The multiple entity data model which contains metadata that associate two or more entities is applied recordkeeping metadata standard in recent years. This paper described and analyzed the recordkeeping metadata standard applying multiple entities such as ISO 23081, Australia recordkeeping metadata Standard, New Zealand recordkeeping metadata Standard, New South Wales recordkeeping metadata Standard, Queensland recordkeeping metadata Standard recordkeeping metadata Standard, South Australia recordkeeping metadata Standard, focusing on scope, the number of entities, category in entity, metadata elements. And shows some examples of relationship entity which is the key of multiple entity. As a result of the analysis, this paper suggests some consideration when recordkeeping metadata standard applying multiple entities is revised.

  • A taxonomic study of the family Zoarcidae was conducted using fish collections deposited in the Department of Biology, Chonbuk National University, Jeonju, Korea and the East Sea Fisheries Research Institute, Korea. Among these collections, the following four species of the genus Lycodes are recognized as the first records for Korea; L. sadoensis, L. japonicus, L. pectoralis, and L. sigmatoides. These species are here redescribed and figured, with their distributions and a provisional key to five genera and eleven species of the family Zoarcidae from Korea.

  • This study suggests a general process of analyzing the mooring and cargo handling limit waves, which is an incident to the new energy port under long wave agitation. To reduce damages of ships and harbor structures due to strong wave responses, it is necessary to predict the change of wave field in the mooring berth to make the proper decision by dock master. The berthing area at a new LNG port in the east coast of Korea in this study is frequently affected by oscillations from waves of 8.5~13s periods in the wintertime. The long period waves give difficulties on port operation by lowering the annual berthing ratio. It needs to find the event waves from the real time offshore wave records, which cause over the mooring limits. For that purpose, the wave records from field measurement and offshore wave buoy were analyzed. From numerical simulation, the response characteristics of long period waves in the berthing area were deduced with or without breakwater expansion plan, analyzing the offshore field wave data collected for two years. Some event wave cases caused over the cargo handling and mooring limits as per the standard Korean port design guideline, and those were used for the decision of port operation by dock master, comparing with the real time offshore wave observations.

  • Three new records of Ascomycota species (Chaetomium acropullum, Phialemonium globosum, Phialemonium atrogriseum) from field soils in Korea are presented in this study. These newly discovered fungal isolates were isolated from field soils from various places across Gyeongnam, Korea in 2016. All the isolates were identified and described based on morphological characteristics, and rDNA internal transcribed spacer and ${\beta}$-tubulin gene sequence data. Morphological features of these fungal species were studied on different agar media: potato dextrose agar, oatmeal agar, malt extract agar, Czapek yeast extract agar, and yeast extract sucrose agar. Full description and illustrations of their morphological characters are provided. These fungal species have not officially been previously reported in Korea.
