  • The objective of this study is to develop a knowledge-based scheduler applying simulation and knowledge base. This study utilizes a machine induction to build knowledge base which enables knowledge acquisition without domain expert. In this study, the best job dispatching rule for each order is selected according to the specifications of the order information. And these results are built to the fact base and knowledge base using the attribute-oriented induction method and simulation. When a new order enters in the developed system, the scheduler retrieves the knowledge base in order to find a matching record. If there is a matching record, the scheduling will be carried out by using the job dispatching rule saved in the knowledge base. Otherwise the best rule will be added to the knowledge base as a new record after scheduling to all the rules. When all these above steps finished the system will furnish a learning function.

  • The genus Chrysothrix is very common around the world and easy to be recognized by its bright yellowish granular thallus. In this study, investigations of lichen mycota in South Korea and Chile from 2010 to 2017 have been done, and some Chrysothrix specimens were collected, based on the morphological and chemical study on these specimens, five species were confirmed in this study, including one new species from Chile, Chrysothrix chilensis D. Liu & J.-S Hur, and one new record from South Korea, C. xanthina (Vain.) Kalb. Meanwhile, detail description and illustration for each species were present in this study.

  • Two specimens of Apogon cookii of the family Apogonidae were collected from the coastal waters of Dokdo, Korea, and described as the first record from Korea. Specimens were caught by SCUBA diving using scoop net (length 33 cm, depth 63 cm) on October, 1997. The species differs from A. endekataenia in having 5 longitudinal stripes and a small black spot on the base of caudal fin. The new Korean name, "Da-seot-jul-eol-ge-bi-neul" as new Korean name of Apogon cookii.

  • The euphausiid crustacean Stylocheiron abbreviatum G. O. Sars, 1883 has been found in the southern waters of Jeju Island, Korea. This species is the third member of the genus Stylocheiron and the twelfth of the family Euphausiidae identified in Korean waters. Using descriptions of this species, a key to Korean euphausiids is presented.

  • Herein, we report a new record of Notodontidae moth, Neodrymonia marginalis (Matsumura) in Korea. This species is characterized by grayish forewing that shows thick dark grayish band between basal and antemedial line, smooth postmedial line costally with blackish crescent line, dark grayish subtermen with dark brownish thick band costally, and whitish and black dot shaped discal dot. The female genitalia can be distinguished by the broad, plate-shaped postvaginalis, strongly sclerotized ductus dursae with three long spike shaped and several small spike shaped processes, and large, ovate corpus bursae with a large fan-shaped plate signum. Neodrymonia marginalis can be distinguished from N. deliana by the shape and color of the costal part of postmedial line and subtermen of forewing. The female genitalia of N. marginalis can be distinguished from those of N. deliana by the rectangular postvaginalis and more spike like processes of the anterior of ductus bursae. Up to now, four species of Neodrymonia are recorded in Korea: N. delia (Leech, 1889), N. coreana Matsumura, 1922, N. deliana Gaede, 1933, and Neodrymonia marginalis.
