  • The Mesostigmata is an order of Subclass Acari either parasiting to diverse invertebrates or free-living predatory in terrestrial ecosystem. Phoresy is one of the unique behaviors of wingless arthropod dispersal by attaching winged arthropods. We collected mites attached on the dorsal part of abdomen adult sciarid fly, from mushroom culture. The mites were identified as Arctoseius cetratus Sellnick, 1940 in the family of Ascidae. Arctoseius cetratus has short J2, Z1, Z2, and S1, S2 setae, not reaching the bases of following setae. Posterior half of dorsal shield with longitudinal garland of puncta between J and Z setae, peritremes extending anteriorly to midlevel of coxaII. The genus Arctoseius and species Arctoseius cetratus are the first record in Korea. We provided the detail description of the species including the identification key in the family with some ecological notes.

  • The purpose of this study was to examine the usefulness of Beavers Systems Model on adolescent adjustment. For this study adolescents' perceptions of family health/competence family style and adolescent adjustment were utilized. The 443 subjects were selected randomly from the second grade of middle schools and high schools in the city of Taegu. The instruments of measurement were SFI II State-Trait Anxiety Inventory Depression Scale Self-Esteem Scale and Delinquency Scale. Factor Analysis Cronbach's a, MANOVA and Scheffe test were conducted for the data analysis. The conclusion of this research findings was as follows: There is significant differences I nadolescents' anxiety depression global self-esteem social-peer self esteem property predatory behaviors and school-norm avoidant behaviors by the family functioning types of BSM. Therefore the group classification by BSM was generally useful in evaluating adolescent adjustment.

  • Korean fauna mites in the family Parasitidae of Mesostigmata were reported as 6 genera, 22 species. Among those 20 species were recorded from Northern part of Korea by Athias-Henriot (1977; 1980), Daele (1975) and Tichomirov (1977), but two from Southern part of Korea by Choi (1994) and Korean zoological record (KSSZ, 1997). During the faunal study of soil predatory mites of diverse habitats in South Korea, four species of P. beta, P. fimetorum, P. insignis and Poecilochirus carabi are the new records to Korean peninsula. Taxonomic details and other biological characteristics are reported.

  • The family Olividae includes predatory species with medium-sized, glossy, elongated oval-shaped shell. As sand-dwellers, they are broadly distributed in tropical and subtropical oceans. They feed mostly on other mollusks and carrions including sea snails and bivalves. To date, two species in the genus Amalda (subfamily Ancillinae) have been reported in Korean waters. In this study, Amalda rubiginosa (Swainson, 1823) was collected from Korean waters and morphologically described in details as a first record.

  • Monacroporium ullum sp. nov. the captures nematodes on adhesive spherical knobs was isolated from soil around Codonopsis lanceolata at Ulleung island, Korea. The spindle-shaped conidia sized $17-44{\mu}m\;(26.5{\mu}m)\;long,\;7-10{\mu}m\;(8.1{\mu}m)$ wide, containing from 1 to 4 cross-walls but most often divided by 2 septa (47%). Resting bodies sized $57{\times}30{\mu}m$. Arthrobotrys amerospora has almost spherical non-septate conidia with a small truncate protuberance at the base and sized $20-27{\mu}m\;(23.3){\mu}m$ long and $11-17{\mu}m\;(14.1){\mu}m$ wide. Conidiophores are somewhat longer $362.8{\mu}m\;(311-418{\mu}m)$ than its original description ($75-250{\mu}m$).

  • Dactylella pseudoclavata that captures nematodes in adhesive networks was isolated from nematode-infested strawberry plants from Andong, Korea. It produces obclavate, 0-1 septate conidia, $30-40{\mu}m$ long and $8-11{\mu}m$ wide, with round distal ends and bases shaped like bottle-necks. The conidiophores were simple, occasionally branched, $150-300{\mu}m$ long, producing 1-4 conidia at the apex. Chlamydospores were abundant, intercalary or catenulate, yellowish to brown, globate or subglobate, wart on the surface, $30-35{\times}25-30{\mu}m$ in size. This is the first report of Dactylella pseudoclavata in Korea.

  • The 9th Indo-Pacific Fish Conference (IPFC9) was held in Okinawa, Japan from 24th to 28th June 2013. Five hundred and thirty two delegates from 36 countries/regions around the world attended. The Conference took place with a welcome address by Dr. Keiichi Matsuura in the Laguna Garden Hotel next to the Okinawa Convention Center in the evening of 23rd June 2013, one day before the official start of the IPFC9. The winners of the two IPFC9 Bleeker Awards, Jeffrey M. Leis (Ecology) and Gerald R. Allen (Systematics) provided excellent talks on "Change in the early life-history of Indo-Pacific Fishes" and "The center of Indo-Pacific reef fish diversity". A total of 462 papers were presented, including 328 oral and 134 poster presentations. The main themes of IPFC9 included systematics, evolution, zoogeography and phylogeography, biodiversity, ecology, behavior, and conservation. There were 14 symposia, which included topics such as "Top predatory fish in the Indo-Pacific ecosystems", "Fish diversity across environmental extremes", "Ontogeny and systematics of Indo-Pacific fishes", and "Phylogenetics and diversification of the Percomorpha". IPFC10 will be held in Papeete, Tahiti.

  • This paper tries to find out the prevalence of the school violence among the elementary school children and explores variables to explain the violence based on the various victimization theories including the life style theory. One out of ten respondents reported that they had at least one experience of victimization. Bullying was found out to be the most frequent type of the school violence. The school violence experience are shown to have no statistical significant relationship with the life style of respondents, the family background, and the academic achievements, but to have relatively high correlation to delinquency propensity. This may indicate that both offender and victim of the school violence could be recruited from the same group.

  • Utilization of small robots in psychology and biology provides a new breakthrough in understanding the neurobiological mechanisms of various animal behavior. The expansion of robot use in animal research is partly due to increased availability of economically plausible mobile robots and also due to the current shift in animal research toward more ecologically valid experiments. Ground-breaking experimental findings are expected when the behavioral variables are manipulated in more natural situations. In addition, the results from laboratory could be generalized more easily with added ecological validity. The current paper attempts to review a wide range of applications of animal robots used to study animal behavior and to highlight major advantages and limitations. In particular, this review focuses more on the psychological impact of animal robots than engineering details about their structure and operation. Finally, this review will provide some practical considerations when employing robots in animal experiments.
