Henricia specimens were collected using fishing nets from the East Sea of Korea. The specimens were identified as Henricia oculata Pennant, 1777, belonging to the family Echinasteridae of the order Spinulosida. This species can be distinguished from other Henricia species by broad arms (R/r=4-4.1), rough skin, a thick arm base, three to nine minute delicate abactinal spines, and inferomarginal plates reniform in shape. This species superficially resembles H. pachyderma in its body size and wide papular areas but differs mainly in the number of papulae and abactinal spines, and the shape and arrangement of the inferomarginal plates. To date, two genera of Echinasteridae, Aleutihenricia and Henricia, with a total of 13 species, have been reported in Korea. The morphological characteristics of H. oculata are described, and photographs are provided.

In this study, the community structure of marine benthic invertebrates was examined to evaluate the differences between the west, south, and east coasts of Korea and to identify the indicator species representing each region. Acrylic attachment plate sets were installed in Jeongok, Mokpo, Tongyeong, Yangpo, and Gangreung, and the invertebrate fauna thus captured were identified. Monitoring was performed in each area from March 2017 to May 2018. Water depth, temperature, and salinity at each location were measured to determine the potential influence of abiotic factors on the community structure. As a result, the mean depth of plates installed and the water temperature were significantly different in each area. A total of 32 invertebrate species were identified in all localities, and the most significant difference in the species compositions was found between Mokpo and Gangreung. The community structure differed significantly with a change in the plate depth, and a larger number of indicator species appeared on shallower plates. Finally, we determined the community structure of benthic invertebrates in different geographical regions of the Korean ocean by characterizing the dominant invertebrate taxa and the indicator species at each site.

An asteroid specimen was collected by using a fishing net from the waters near Daejin harbor, in the East Sea of Korea on 3 Mar 2017. Based on morphological characteristics, the specimen was identified as Aleutihenricia beringiana (Djakonov, 1950), belonging to the family Echinasteridae, of the order Spinulosida. The genus Aleutihenricia was first described by Clark and Jewett, 2010. This species can be distinguished from other Aleutihenricia species by having a roundish protruding shape of abactinal and actinal plates, the number of abactinal spines bearing three to eight spinelets, and the number of adambulacral spines comprising six to eight spinelets. This is the first report of the genus Aleutihenricia and A. beringiana in Korea.

The Journal of the Korean Solar Energy Society is the first journal in South Korea that adopts wind energy as one of its subjects. Since 2000, more than 140 papers on wind energy have been published in the journal, which accounts for 8.5% of the total publication. However, in recent years, the number of published papers on wind energy has been decreasing steadily, and a reason for this decline is the significant dependence on a few specific institutions and authors. In this study, wind energy subjects were classified using the frequency analysis of the subject words extracted from the title, keywords, and abstract of wind energy papers using the text mining technique. In addition, the Korea Citation Index was used to perform quantitative level evaluation by subject and institution and to analyze the trends and characteristics of the wind energy field. Therefore, it was identified that in terms of the number of publications and citations, the main subject areas were resource/micrositing and policy/potential.

Astilbe rubra (AR) is a perennial, belongs to the Saxifragaceae family, it contains tannin and triterpene. AR has been used in republic korea to improve toxication, fever, pain and convulsion. Recently, number of natural products have been analyzed for potential pharmacological activities including anti-cancer, anti-obesity and anti-diabetic medication. Consequently, we investigated the growth inhibition effect of Astilbe rubra water extract (WAC), ethanol extract (EAC) and bergenin on Hela cell (human adenocarcinoma cell). From whole plant of A. rubra, bergenin was isolated by column chromatography and its structures were identified by $^1H$, $^{13}C$ NMR and IT TOF-ESI MS. High extraction efficiency of bergenin was shown at 0.95% under 60 min reflux extraction with 50% MeOH. The MTS assay showed that EAC (ethanol extract) treatment increased cell death in a dose-dependent manner. Moreover, EAC treatment on Hela cell increased apoptotic cell death and caspase-3 activity. Results suggest that EAC has growth inhibition effect on Hela cells, but not WAC and bergenin. $500{\mu}g/mL$ EAC treatment inhibited Hela cell at $60.2{\pm}1.5%$.

Host's data during transmission. Data tempering results in loss of host's sensitive information, which includes number of VM, storage availability, and other information. In the distributed cloud environment, each server (computing server (CS)) configured with Local Resource Monitors (LRMs) which runs independently and performs Virtual Machine (VM) migrations to nearby servers. Approaches like predictive VM migration [21] [22] by each server considering nearby server's CPU usage, roatative decision making capacity [21] among the servers in distributed cloud environment has been proposed. This approaches usage underlying server's computing power for predicting own server's future resource utilization and nearby server's resource usage computation. It results in running VM and its running application to remain in waiting state for computing power. In order to reduce this, a decentralized decision making hybrid model for VM migration need to be proposed where servers in decentralized cloud receives, future resource usage by analytical computing system and takes decision for migrating VM to its neighbor servers. Host's in the decentralized cloud shares, their detail with peer servers after fixed interval, this results in chance to tempering messages that would be exchanged in between HC and CH. At the same time, it reduces chance of over utilization of peer servers, caused due to compromised host. This paper discusses, an roatative decisive (RD) approach for VM migration among peer computing servers (CS) in decentralized cloud environment, preserving confidentiality and integrity of the host's data. Experimental result shows that, the proposed predictive VM migration approach reduces extra VM migration caused due over utilization of identified servers and reduces number of active servers in greater extent, and ensures confidentiality and integrity of peer host's data.

Securing reference information (inventory) is essential for proper conservation and management of protected areas. Moreover, the investigation results should be available for comparison and evaluation. For this study, we established seven investigational lattices and carried out the field examinations to obtain comparable data in the Donggang river basin ecological and scenery conservation area, We conducted a total of 16 field surveys and identified a total of 830 taxa that is composed of 127 families, 408 genera, 716 species, 10 subspecies, 88 varieties, and 16 forms. We identified a total of 487 taxa in the 6th investigational lattice and 457 taxa in the 4th. We observed 6 species (grade II) designated by the Ministry of Environment as the endangered plants, one "species to monitor" designated by the Ministry of Environment, and 23 taxa designated as endemic species. Regarding the floristic characteristics plants, 15 taxa of grade V, 27 taxa of grade IV, 38 taxa of grade III, 31 taxa of grade II, and 19 taxa of grade I were identified. The 6th investigational lattice showed the largest number of taxa at 70. A total of 58 taxa were identified as the naturalized plant, and the 6th investigational lattice showed the most at 35 taxa. The Donggang river basin ecological and scenery conservation area was assessed to be an extremely important area to conserve and maintain plants species diversity not only in the regional scale but also national scale.
