  • Korean species of the genus Euodynerus Dalla Torre were taxonomically reviewed. Four species were confirmed: E. trilobus, E. dantici violaceipennis, E. nipanicus nipanicus, and E. quadrifasciatus atripes. The specimens previously identified as E. dantici brachyotomus and E. notatus pubescence form North Korea were re-examined, and corrected to E. dantici violaceipennis and E. nipanicus nipanicus, respectively. Euodynerus quadrifasciatus atripes was re-described for future researchers. After careful reading previous descriptions, Euodynerus seuli Radoszkowski was tentatively supposed to be conspecific with E. nipanicus.

  • The genus Caconemobius comprises marine apterous crickets. In recent years, two species have been confirmed in Korea: Caconemobius sazanami (Furukawa, 1970) and Caconemobius takarai ($\hat{O}$shiro, 1990). A key to species, descriptions, distribution data, photographs, and figures are presented to compare the two crickets.

  • Vespa binghami Vecht, a poorly known vespine species, was discovered in Korea. This is the second treatment of this species on the Korean peninsula since the first report on Korean occurrence by Virula in 1925; however, the first one was based on practical Korean distributional information. Diagnostic description and digital images are provided.

  • Three ichneumonid wasp species of the tribe Poemeniini (Ichneumonidae: Poemeniinae) are redescribed from Korea: Cnastis assimilis (Uchida) (new Korean record), Deuteroxorides orientalis (Uchida) and Eugalta ablimarginalis (Uchida) (new Korean record). A key to the Korean species of Poemeniini, photographs of diagnostic characters, distributional data and host records are provided.

  • Desmotimmia mirabilis (Timm), a rarely known desmoscolecid nematode species, was discovered for the first time from the Yellow Sea off southwestern coast of Korea. This is the third record of the species, and the first report from the northwestern Pacific region. Redescription is prepared on the basis of a male specimen from South Korea.

  • In the present study, nine species of the family Braconidae are recorded for the first time from Korea: Bassus ussuriensis (Telenga), Amyosoma yanoi (Watanabe), Calcaribracon nipponensis (Watanabe), Doryctes gyljak Telenga, Rhaconotus signipennis (Walker), Allurus lituratus (Haliday), Hellenius dadianshanicus Belokobylskij, Homolobus rufiventralis Maeto, and Aulacocentrum confusum He & Achterberg. Diagnosis and photographs for the species are provided.

A Study on The Restoration of Substation using Genetic Algorithm (유전 알고리즘을 이용한 변전소 복구 방안에 관한 연구)

  • This paper proposes a method for seeking the scheme of substation restoration by using genetic algorithm. Genetic algorithm (GA), first introduced by John Holland, is becoming an important tool in machine learning and function optimization. GA is a searching or optimization algorithm based on Darwinian biological evolution principle. As a test system, we assume a simple substation system and for the transformer fault, the result is obtained.
