  • Twenty South Korean tiphiid species are taxonomically reviewed. Among them, Tiphia burrelli is new to Korea. Based on the observation of the holotype, Tiphia seoulensis Tsuneki 1986 is synomymized with T rufomandibulata Smith 1873. Male of T koreana hitherto unknown is newly described. Revised key to species, recognizable characters and digital images are provided. Genital structures of several species hitherto unknown are also given.

  • Cupressinocladus sp. found from the upper part of the Jinju Formation of the Shindong Group, Korea is described here based on the newly found leafy shoots. This species is characterized by the branched leafy shoot with decussate scale leaves. The presence of Cupressinocladus in the Jinju Formation indicates that the Early Cretaceous flora-sites in Eastern Eurasia are in a close association with territories of the mixed-type floras. The finding of this species records the first report for the Nakdong flora.

  • Paraplectana sakaguchii Uyemura, 1938 is a ultra rare species belonging to Araneidae worldwide. This species was collected by sweep net between the shrubs at the foot of mountainous region in August, 2012. This species is briefly described and illustrated in this report. The spider genus Paraplectana is also newly recorded to Korean spider fauna.

  • This paper presents a newly developed speed sensorless drive using RLS based on Neural Network Training Algorithm. The proposed algorithm has just the time-varying learning rate, while the wellknown back-propagation algorithm based on gradient descent has a constant learning rate. The number of iterations required by the new algorithm to converge is less than that of the back-propagation algorithm. The theoretical analysis and experimental results to verify the effectiveness of the proposed control strategy are described.

  • Eight caprellids are collected from the several islands off Yeonggwang, Jeollanam-do at June 2007. Among them Caprella chelimana Mayer, 1903 is newly added to the Korean caprellid fauna. We described this species with illustrations and mentioned some differences from Mayer's original descriptions. Caprella subtilis is also the first record since Mayer reported this species from East Sea (Sea of Japan) in 1903.

  • An Uraniidae moth, Lyssa zampa (Butler, 1869) is newly discovered from southern Korea. One male specimen was collected at a valley of south aspect of Mt. Hallasan, Jejudo in July, 2014. This species is briefly described and illustrated here. DNA barcoding sequence (Genbank KU160388) for the species was provided for species identification.
