Archaea are prokaryotic organisms distinct from bacteria in the structural and molecular biological sense, and these microorganisms are known to thrive mostly at extreme environments. In particular, most studies on halophilic archaea have been focused on environmental and ecological researches. However, new species of halophilic archaea are being isolated and identified from high salt-fermented foods consumed by humans, and it has been found that various types of halophilic archaea exist in food products by culture-independent molecular biological methods. In addition, even if the numbers are not quite high, DNAs of various halophilic archaea are being detected in human intestines and much interest is given to their possible roles. This review aims to summarize the types and characteristics of halophilic archaea reported to be present in foods and human intestines and to discuss their application as well.

Green roof systems has widely been used on rooftop of buildings by considering environmental benefits in aspects of bio-diversity, storm-water runoff as well as noise reduction. To predict noise reduction effect by green roof systems, it is necessary to measure in-situ acoustical properties of the components by devices enabling in-situ measurements. In this study, Micro-flown, which is the state of the arts device to measure in-situ normalized impedance and absorption coefficient has been used to measure acoustical properties of green roof materials according to different water saturation condition in the materials.

One of the most economically viable processes for the bioconversion of many lignocellulosic waste is represented by white rot fungi. Phanerochaete chrysosporium is one of the important commercially cultivated fungi which exhibit varying abilities to utilize different lignocellulosic as growth substrate. Examination of the lignocellulolytic enzyme profiles of the two organisms Phanerochaete chrysosporium and Rhizopus stolonifer show this diversity to be reflected in qualitative variation in the major enzymatic determinants (ie cellulase, xylanase, ligninase and etc) required for substrate bioconversion. For example P. chrysosporium which is cultivated on highly lignified substrates such as wood (or) sawdust, produces two extracellular enzymes which have associated with lignin deploymerization. (Mn peroxidase and lignin peroxidase). Conversely Rhizopus stolonifer which prefers high cellulose and low lignin containg substrates produce a family of cellulolytic enzymes including at least cellobiohydrolases and ${\beta}-glucosidases$, but very low level of recognized lignin degrading enzymes.

Copepods play an important role as a primary consumer in the various aquatic ecosystems. Most of marine benthic copepods belong to the Order Harpacticoida, and are known over 3,000 species in the world. Research on the biodiversity of the benthic copepods are important in the development of the new bio-resources, and the genetic resources. The importances and the prospects of biodiversity research on the mavins benthic copepods are discussed.

A cuckoo wasp species Nipponosega yamanei Kurzenko & Lelej is recorded in Korea for the first time. Of the two forms known from Japan, it is more similar to yamanei-form than kantoensis-form: eye margin almost evenly rounded in frontal view. The species of the two subfamilies, Chrysidinae and Cleptinae, have been listed for the Korean fauna. This species is the first representative of the third subfamily Amiseginae in Korea. It is known to be endemic to Japan. Thus, the distributional range of this species has been extended to the continental part herein. A description is made for further morphological comprehension on the basis of Korean materials.

The varunid crab, Varuna yui Hwang & Takeda, 1986, is known as widely distributed in the Southeast Asian region. Three specimens of varunid crabs were collected near the estuary of the river from Korea and identified as V. yui. Varuna yui could be distinguished from the other congeneric species, V. litterata (Fabricius, 1798), by having a more extended mesial lobe on the distal region of the male first gonopod. In this paper, morphological diagnosis and illustrations of the newly collected V. yui are provided. The specimens examined herein were deposited in the National Marine Biodiversity Institute of Korea and Nakdonggang National Institute of Biological Resources.

Background: The understanding of ecosystem services can be quantified and qualitative to assess the impacts of changes in the ecosystem to support human well-being. In the Democratic People's Republic of Korea, sustainable use of ecosystem services has attracted the interest of a range of decision-makers. However, although there is a concern for biodiversity, natural ecosystem, and their services, linking ecosystems with conservation planning remains challenging. Results: This study assessed the first qualitative ecosystem services provided by the Mundok wetland with decision makers of the West/Yellow Sea region. Furthermore, this study applied the Rapid Assessment Wetland Ecosystem method to support natural resources management, improving living conditions. We identified that cultural and supporting services index are highly provided, but preparing a plan to increase the provisioning and regulating services in Mundok wetland is necessary. Conclusions: The assessment results can provide helpful information for ecosystem services assessment, habitat conservation, conservation planning, and decision-making at local level.

The genus Teloganopsis Ulmer belonging to the family Ephemerellidae is only known from the species of T. punctisetae (Matsumura, 1931) in the Korean Peninsula. The members of the genus Teloganopsis are characterized by the following characteristics: head and abdominal tergites without any tubercles and complex setae; forefemur with a row of long and stout setae perpendicularly; maxilla covered with dense setae. A total of 17 species had been previously recorded in this family. Here, Teloganopsis chinoi (Gose, 1980), is newly recorded in Korea which was found under a large stone in Kyeongho river. Larval habitus, habitat, line-drawings of key characters of the species, a checklist with habitus photos of Korean Ephemerellidae, and a key to the larvae of Korean Teloganopsis are provided.

In this article, a phyllidiid nudibranch which is distributed widely in the Indo-Pacific region, Phyllidia varicose Lamarck, 1801, is reported based on a specimen collected from Seopseom Islet, Jeju Island, Korea. This species is characterized by bluish-gray dorsal tubercles with a yellow cap and three distinct ridges consisting of dorsal tubercles going from the anterior to posterior region, the presence of bluish-black pigment between the dorsal ridges, and a characteristic black longitudinal stripe along the midline of the sole. In this study, we provide a key to species belonging to the genus Phyllidia discovered in Korea, the morphological descriptions, photographs, and a sequence of partial mitochondrial cytochrome c oxidase subunit I of P. varicosa. Currently, four species of the genus Phyllidia have been reported to be present in Korea, including P. varicosa.

A taxonomic review of the Korean Chrysis smaragdula group (Hymenoptera: Chrysididae), characterized by the six apical teeth (including lateral angles or obtuse protuberances) of metasomal tergum 3, is presented. Three species, namely Chrysis daphne, C. equestris, C. principalis, are included herein. Of these, C. equestreis is recorded from Korea for the first time. Chrysis daphne is a corrected name for the previous Korean records under the name of C. fasciata. A determination key to species complemented with illustrations is made. Additional diagnoses including color variations and descriptions of male genitalia (unavailable in C. equestris) based on Korean materials are also provided.
