This research was conducted to find the indigenous diatom species unrecorded in Korea from February to December 2016. The samples were taken at 28 sites of the coastal regions on the west coast of Korea and Jeju Island. Diatoms were collected mostly from sand and mud of tidal flats, including gravel, seaweed on the bottom and macrophytes floating in the seawater. Diatom specimens were observed by means of light and scanning electron microscopy. Twenty one species were discovered and added as new specimens to the Korean diatom flora, which are divided into 9 orders, 12 families, and 16 genera. The list and photographs of the species are included with the description of the morphological characteristics and distribution in Korea.

Gangjeong Village where Jeju's naval base was built, it has been so beautiful and prosperous that it was called Jeju Island's 'Jeil Gangjeong'. The relationship among Dongseonyeok Jip and U-alnyonk-Jip(It means neighborhood in Jeju dialect), Gapjang (It means same age friends), Guendang(It means kin) and relatives, alumni and older alumni or junior become estranged. Now, Gangjeong Village is in its biggest crisis since it was founded. Gangjeong is a national treasure protection zone designated as natural monument No.442, designated as a UNESCO Biosphere Reserve area, The nearby area is designated as the Marine Conservation Zone designated by the Ministry of Maritime Affairs and Fisheries and Jeju Provincial Marine Park, and Gurumbi is ecologically excellent, designated as the absolute conservation zone and the absolute conservation coast of Jeju Island. So, it was designated as a fishing village experience town in 2004 and a superior natural ecology town in 2006. However, in 2007, the village president and several others ignored the procedures and decided to run the village as a candidate for the naval base. The navy and then the governor of Jeju Island accepted the decision and chose it as the site for the naval base. In February 2016, Jeju naval base was completed despite protests from residents of Gangjeong Village, numerous residents of the island, and the public. Gangjeong Village was chosen as the site of a naval base in April 2007 when 87 among 1,200 voters decided to attend an extraordinary general meeting. In response, a counterproposal committee was set up in the village, and on August 10, 2007, the former village president who led the bid for the naval base was dismissed at an extraordinary general assembly, and a new village president was elected. And on August 20 of that year, 94 percent of the absolute majority at the town assembly with 725 members opposed the construction of a naval base.

In this paper, a mathematical model of regionalization based on graph theory to investigate the patterns induced by movements of livestock vehicles in cities under outbreaks of highly pathogenic avian influenza (HPAI) is proposed. We then compare the results of simulation from the regionalization model to actual HPAI outbreaks in 2016/2017 to evaluate the validity of the model. Specifically, we (1) configured a complex network structure with analytic tools and properties in graph theory to abstract the paths among farms and livestock facilities; (2) employed statistical methods to estimate the possibility of propagation between two clusters; (3) applied the developed method to an actual HPAI outbreak in Korea in 2016 and conducted a simulation to determine if the proposed modeling for regionalization is an effective prediction measure. The clustered regions proposed by the simulation correctly reflected the regional clustering of actual cases, while simultaneously contain the cities exposed to potential damage when separated. Based on these findings, we conclude that our proposed regionalization model is suitable for making policy judgments to establish a preemptive biosecurity system.

Hallasan is an elliptical volcano on Jeju Island and is the highest mountain in South Korea. A survey was carriedout to investigate soil Gamasina mite composition in the Hallasan National Park during 2016-17. Soil samples were collectedvarious microhabitats from Baekrokdam and Muljangori. We found these eight species; Euparholaspulus primori, Gamasholaspisbrowningi, G. communis, Parholaspulus bregetovae, P. hiasmaticus, P. maturovae, P. orientalis and P. paradichaetes fromsoil. Among these species, Parholaspulus bregetovae, P. hiasmaticus, P. maturovae, P. orientalis and P. paradichaeteswere first records from Baekrokdam and Muljangori, Halla National Park, South Korea.

Bryopsis africana and Pyropia kinositae are reported for the first time on the list of Korean marine algal flora based on integrated morphological-molecular study. Bryopsis africana from Korea is recognized with distinct main axes, robust thalli, pinnately and radially branched above, and basally denuded. Phylogenetic analyses revealed that B. africana was placed within a clade of Bryopsis. Bryopsis africana differs from B. corymbosa by 2.7% gene sequence divergence. Pyropia kinositae is characterized by oblong to lanceolate thalli, entire margin, purplish red in color, twice as long as broad cells in transversal section view. Phylogenetic analyses revealed that P. kinositae was placed within a clade of Pyropia. Pyropia kinositae differs from P. tenera by 1.5-1.8%, P. ishigecola by 1.2-1.3%, and P. yezoensis by 1.5-1.8% gene sequence divergence respectively.

Detailed morphological studies and molecular analyses based on plastid-encoded rbcL gene sequences were undertaken on Peyssonnelia species, a poorly known genus from Korea. We report new records for the Korean coast, Peyssonnelia harveyana and P. rumoiana. Peyssonnelia harveyana is chiefly characterized by P. rubra-type anatomy, closely packed perithallial filaments in firm matrix, hypothallial filaments arranged in parallel rows, thalli with appressed margins, hypobasal calcification, and unicellular rhizoids. Peyssonnelia rumoiana is principally characterized by two vegetative features, hypothallial filaments arranged in a polyflabellate layer, and perithallial filaments arising from the whole upper surface of each hypothallial cell (Peyssonnelia rubra-type anatomy). Our rbcL analyses revealed that P. harveynana and P. rumoiana were placed within a clade of Peyssonnelia. We also propose the new combination, Sonderophycus cauliferus comb. nov., for previous Peyssonnelia caulifera. Phylogenetic analyses revealed that our S. cauliferus was placed within a clade of Sonderophycus.

Aphidiinae in Braconidae includes more than 400 species within approximately 60 genera worldwide. Species of Aphidiinae are mostly known as solitary koinobiont endoparasitoids specifically associated with aphid hosts, and some of them are used for biological control. In the present study, two aphiniine species are newly recognized from South Korea based on morphological and molecular study: Aphidius rhopalosiphi de Stefani-Perez 1902 and A. uzbekistanicus Luzhetzki 1960. Although It was very difficult to discriminate two species morphologically, we cleary identified them by using COI (cytochrome c oxidase subunit I) DNA Barcode sequences. Here we present their morphological descriptions, illustrations and barcoding results.
