A new euthyplociid burrowing mayfly (Polymitarcyidae, Ephemeroidea, Ephemeroptera), Polyplocia orientalis n. sp., from Vietnam is described with larval habitus and line drawings of mouthparts. The larva of the species is characterized by the mandibular tusks that bear numerous hairlike and stout setae on their dorsal and lateral surfaces and by the apical process of foretibiae that is nearly one-fourth the length of foretarsi. Its habitat and biological data and taxonomic remarks are provided. The burrowing mayfly subfamily Euthyplociinae is reviewed from a historical perspective.

As a result of continuous taxonomic investigations of Korean crabs, Pugettia intermedia Sakai, 1938 is newly reported from Korean waters. Pugettia intermedia had previously been reported in Korean fauna, but the previous reports of P. intermedia were resulted in misidentification of P. quadridens (De Haan, 1839). Pugettia intermedia differs from P. quadridens in having two subequal medial lobes of the first pleopod in male. In P. quadridens, one of the two medial lobes is about half-length of the other. Pugettia intermedia occurs on the southern coast of the Korean peninsula. The descriptions and illustrations of this species are provided herein.

In distributed autonomous robotic systems (DARS), each robot must behave by itself according to its states ad environments, and if necessary, must cooperate with other robots in order to carry out their given tasks. Its most significant merit is that they determine their behavior independently, and cooperate with other robots in order to perform the given tasks. Especially, in DARS, it is essential for each robot to have evolution ability in order to increase the performance of system. In this paper, a schema co-evolutionary algorithm is proposed for the evolution of collective autonomous mobile robots. Each robot exchanges the information, chromosome used in this algorithm, through communication with other robots. Each robot diffuses its chromosome to two or more robots, receives other robot's chromosome and creates new species. Therefore if one robot receives another robot's chromosome, the robot creates new chromosome. We verify the effectiveness of the proposed algorithm by applying it to cooperative search problem.

A new genus Goodingius is proposed to incorporate Hemicyclops adhaerens(Williams), H. arenicolae Gooding, H. elongatus Wilson and H. subadhaerens Gooding, all of which bear the six-segmented female urosome, three mandibular elements (or three elements plus one rudimentary setule), five setae on the first antennular segment, and no inner coxal seta of leg 4. The genus Giardella Canu, a sister taxon of Goodingius, is redefined as possessing eight elements on the third exopodal segment of leg 3, only a single inner seta on the second endopodal segment of leg 4, four spines on the third endopodal segment of leg 4. To the genus Giardella, Hemicyclops caissarum Kihara and Rocha and H. carinifer Humes are assigned, in addition to Giardella ricoensis n. sp., Giardella callianassae Canu, and G. thompsoni A. Scott. Keys to the species of both genera are provided.

We synthesized new ${\alpha}$-amidoketenes using dehydrochlorination from anilines, triethylamine and malonyl dichloride under $0^{\circ}C$. The utility of ketenes in both laboratory and industrial practice was quickly recognized, and these species have been extensively utilized, including as pharmaceutical intermediates and anti-cancer agents. All synthetic process from anilines to ${\alpha}$-amidoketenes could be carried out by one-pot reaction. Synthetic ketenes 2a~f were identified using NMR and IR spectrum. Formation of ketenes was undertaken with dropping of malonyl dichloride at $0^{\circ}C$ in methylene chloride for 0.5~4 h. Using malonyl dichloride was better than using diethyl malonate as a synthetic reagents for the ketenes.

1990년부터 1995년까지 우리나라 전 연안에서 채집된 보리멸속 Sillago 어류의 표본을 검토한 결과 지금까지 국내에 출현한다고 보고된 보리멸과 청보리멸의 2종 외에 우리나라에서는 기록된 적이 없는 종인 점보리멸(국명신칭) Sillago parvisquamis가 1995년 3월 25일 여수에서 1개체(체장 166.6mm)채집되었다. 이 미기록종을 포함한 보리멸속 어류 3종의 검색표와 국내 출현 개체들의 측정치를 제시하고 분류학적으로 논의하였다. 한편 우리나라에서 흔하게 출현한다고 알려진 보리멸은 알려진 것과 달리 본 연구에서 1개체도 채집되지 않았다.

It is well known that certain classes of dye are reducible to stable colorless leuco compounds, which can be oxidized in air back to the colored species. We now reported that bis(4-dialkylaminophenyl)squaraine dyes are readily reduced in solution by borohydride to give alkali soluble leuco compound, which exists in the 3-hydroxy 2,4-bis(4-dialkylaminophenyl)cyclobuten-one. New alkylamine leuco compounds were synthesized by the reaction of leuco chloro-squaraine with alkylamine derivatives. The leuco compounds are easily isolated and can be air oxidized back to the squaraine dyes. These dyes have many technical application. e.g. in xerography, solar cell, optical recording material, redox indicators, and enzyme assays.
