  • Morphological and molecular information about two microfilamentous endophytic algae of the Grateloupia lanceolata or Bryopsis sp. from Korea is given. Of two endophytes, Phaeophila dendroides is endophytic in Grateloupia lanceolata. It is green in color and composed of uniseriate branched filaments with long setae. Each cell had several pyrenoids. Undulate or twisted Phaeophila-type hair developed from vegetative cells. Dilabifilum arthropyreniae is endophytic in Bryopsis sp. The frond of this species consists of frequently irregular, branching uniseriate filaments. Each cell had a single pyrenoid without hairs. Sporangia were not observed. The ends of the filaments were curved. In the phylogenetic tree, based on tufA and ITS sequences, these two species are nested in the same clade as Phaeophila dendroides and Dilabifilum arthropyreniae, respectively. In this study, these two species are newly recorded in the Korean marine algal flora, based on the morphological and molecular data.

  • This study aims to design and implement an integrated information retrieval system for the archives in Korea. Particularly, this study is focused on the improvement of the usability of the system. To achieve the goal, this study analyzed the current retrieval systems of national archives and presidential archives in Korea. A new integrated retrieval system, called KAIRS, is designed based on the EAD elements, which is implemented through emulation technic between two retrieval systems. KAIRS showed higher of user satisfaction compared to the existing two retrieval systems in their usability test.

  • Notodelphyid copepods taken from Ascidians, Ascidia samea (Oka) and Ascidia sp. which had been collected in the East sea and the Korea Strait are reported. These copepods are Lonchidiopsis hartmeyeri Vanh ffen, 1917 and Pachypygus curvatus Ooishi 1961, and are redescribed as new records to the Korea fauna.

  • Korean species of the genus Ophion Fabricius are reviewed. Eight species are recognized including two species new to Korea (O. ainoicus Uchida, 1928 and O. choaspese (Uchida, 1954). We provide a key to the Korean Ophion and redescriptions, photographs, distributional data and host records of the newly recorded species.

  • The purpose of this study is to examine the driving forces and main contents of the reform of the records and archives management system in Japan from the 2009 enactment of the Public Records and Archives Management Act. The key essentials of the reform can be explained in two ways. First is through the legal system, a multilayer structure of the law and guidelines to the institutional documents management regulations for an effective application to each administrative institution. The other is the Public Records and Archives Management Commission, a deliberative body that guarantees the rigorous application and enforcement of the rules and regulations. One of the remarkable outcomes from the reform is the compulsory creation of minutes of the countermeasure meetings in government agencies related to the Great East Japan Earthquake Disaster, as well as the various significant cabinet meetings through a revision of the Guidelines for Public Administrative Records Management. In addition, the new construction of the National Archives of Japan and its meaning have been examined. It is being pushed ahead, with the active support of the ruling party members, through activities such as research and review meetings for improving the functions and facilities of the National Archives of Japan.

  • We made a revised catalogue for reliable records of meteor outbursts that were recorded in Korean, Japanese, and Chinese chronicles. In order to avoid the effects of both Earth's precession and perihelion shift, we introduced a new time-coordinate of records, or the number of days elapsed within the sidereal year of the record for a given origin of time or the perihelion passage time of the you 2000. We added nineteen new records of meteor showers that are wrongly classified i, individual meteors in a Chinese archive. We found that the ${\eta}-Aquarids,$ the Perseids, the Orionids, and the Leonids have been active during the last two millennia. Due to the change of time-coordinate, the oldest record of each long-lasting meteor shower has been slightly corrected. We discuss that these long-lasting meteor showers belong to the Halley-type comets.

  • We described two brownish freshwater Cryptomonas species, C. marssonii Skuja and C. pyrenoidifera Geitler as first records in Korea. The identification was based on light microscopy, scanning electron microscopy, and nuclear SSU rDNA sequences analysis. Cryptomonas marssonii is characterized by its sigmoid shape with a sharply pointed and dorsally curved antapex, dorso-ventrally flattened cell, two lateral plastids without pyrenoid, and its dimension of 18-25 μm in length and 8-13 μm in width. Cryptomonas pyrenoidifera is characterized by ovoid to elliptical shape with a partially twisted or rounded antapex, dorso-ventrally biconvex cell, lateral plastids with two pyrenoids, and the dimensions of 15-22 μm in length and 10-14 μm in width. Nuclear SSU rDNA sequences between C. marssonii WCK01 from Korea and CCAC0086 from Gernmay, and between C. pyrenoidifera WCK02 from Korea and CCMP152 from Australia were identical, respectively.

  • Two linyphiid spiders, Saitonia kawaguchikonis Saito & Ono, 2001 and Asthenargus niphonius Saito & Ono, 2001 were confirmed from Korea for the first time. Males of S. kawaguchikonis and a female of A. niphonius were collected with pitfall traps in a leaf litter of mixed forests in three National Parks (Hallyeohaesang National Park, Mt. Naejangsan, and Mt. Sobaeksan) during the seasonal surveys for the spider fauna in mountainous terrain from 2018 to 2020. These two species were formerly known from China and Japan, or only from Japan, respectively. The present study describes these two species with measurements, morphological illustrations, and a distribution map. This report adds the genus Asthenargus Simon & Fage, 1922 from Korea to the Korean spider fauna for the first time.

  • The genus Chroomonas is a group of blue-green colored cryptomonads. This study describes two freshwater Chroomonas species for the first time in South Korea: Chroomonas nordstedtii Hansgirg and Chroomonas coerulea (Geitler) Skuja. We examined the morphology and ultrastructure of these species by light microscopy, scanning electron microscopy, and transmission electron microscopy. These two Chroomonas species were blue-green colored and ovate to oval-shaped. Chroomonas nordstedtii was characterized by two Maupas ovals with hexagonal periplast plates, whereas C. coerulea was characterized by one eyespot with rectangular periplast plates. A molecular phylogeny with data from nuclear SSU rRNA and chloroplast rbcL genes revealed that Korean C. nordstedtii formed a distinct clade with NIES-708, NIES-1004 from Japan, and UTEX 2779 from Colorado, USA, while C. coerulea formed a clade with ACOI 1366 from Portugal.
