The Turbinellidae shell Columbarium pagoda pagoda (Lesson, 1834), from the southern coast of Korea was recorded as new to the Korean molluscan fauna. The shell is typically solid and fusiform, with a well elongated spire and long anterior canal, and keel with a row developed spine. The protoconch is small, planorboid to depressed dome-shaped. The family Turbinellidae is reported from Korea for the first time.

Some bryozoans were collected from the subtidal zone of Manjaedo Island on 23 Aug. 1988. Two species of them, Crepidacantha poissoni (Audouin, 1826) and Hippothoa distans MacGillivray, 1869 turned out to be new to the Korean fauna. The family Crepidacanthidae is new to Korea.

One Iravadiid shell Iravadia (Fluviocingula) elegantula (A. Adams, 1861), from the brackish waters in Kangwon-do was recorded as new to the Korean molluscan fauna. The shell is typically solid and narrowely ovate-conic. The protoconch is small, planorboid to depressed dome-shaped, typically with a minute first whorl. Including the new records in this study, the family Iravadiidae contained 2 genera and 3 species in the Korean water.

Menziesia sebastodis (Capsalidae: Monogenea) is found and described from the gill filaments and the gill rakers of the black rockfish, Sebastes inermis, caught at Dolsan Island, off the south coast of Yeosu, Jeollanam-do, Korea. The genus Menziesia is distinguished from other related genera Benedenia, Megalobenedenia and Trochopus, by septate haptors and the morphology of copulatory organs. M. sebastodis can be differentiated from other Menziesia species by the longer and slenderer posterior anchor, and the location of accessory gland reservoir. This is the first record of the genus Menziesia in Korea.

Appraisal in electronic record environments is performed focusing on not content but function in which the records are created. Functional appraisal is practically supported in that electronic records composed of 0 and 1 of the bit-stream is unable to be evaluated individually. But the most important reason functional appraisal is performed in electronic record environments is that functional appraisal can select electronic records which assure business context and recordness, and need to run organization and perform business. In Korea, functional appraisal has adopted in course of renovation of national record and archive management system, but methods and logics of functional appraisal have numerous problems. To do so, this article discusses current appraisal system and methods of korea which has renovated confronting with electronic record environments, and then proposes the improvement directions on appraisal system and methods of Korea in electronic record environments from the perspective of long-term views. In this respect, this article proposes the improvement directions on current appraisal system and methods of Korea as follows. First, business functional analysis of each agency in functional appraisal should greatly strengthen. Second, it is necessary to devise proper methods for selecting primary values at current stage of electronic records, and to reinforce appraisal of records as knowledges and informations. Finally, functional appraisal, which inevitably carries out for appraising electronic records, has defects in aspect of selecting archives important in a national point of views. Therefore this article suggests the necessity of archival appraisal strategies that complement functional appraisal. This appraisal system is able to establish a base of the regime of archival appraisal which will harmonize primary value at current stage with secondary value at non-current stage in a national point of views.

A marine ulvalean species (Chlorophyta) was collected from Imgok, which is located on the eastern coast of Korea. This species is morphologically characterized by distromatic, filiform to strap compressed or tubular thallus. Many branches were found near the base, but lacked proliferations. Cells were longitudinally aligned in the younger part of the branch and were disordered in the older part of the branch. A cap-like parietal chloroplast with one or two pyrenoids was contained in each cell. In a phylogenetic tree based on ITS and rbcL sequences, this species was nested in the same clade as Ulva torta and U. clathratioides from Australia, but formed a sister clade to U. torta from Japan. However, the genetic divergence between them was included in an intraspecific variation range within Ulva. This finding suggests that U. clathratioides should be reduced to a synonym of U. torta. Accordingly, the Korean alga was identified as U. torta based on the morphological and molecular data. This investigation is the first record of U. torta in the Korean marine algal flora.

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.

First record of a stranded Melon-headed whale (Peponocephala electra) on the south-east coast of Korea was described. Full body and skull measurements were taken from the specimen. It was identified as P. electra by unique pointed flipper tips. Skull measurements of the specimen corresponded to condylobasal length proportions given in the previous descriptions of the holotype.

From birth to death, every man is under the control of the three biorhythm curves that initiate from inner body. body. Those are called 'Physical rhythm, emotion I rhythm and intellectual rhythm'. These biorhythms have influence each other in human behaviour like physical endurance, creativity, record of examination. The result of investigation indicates that the students' records in low level period are lower than those of in high. Therefore, it is verified statistically whether the biorhythm has effects on human ability in scholarly record or not. And also, this research calculates the average nixed-biorhythm which is representable for a group by using mode mixed-biorhythm.

Based on six specimens collected from eastern coast of Jeju Island, Korea, Istiblennius dussumieri is described as a new Korean record representing the northernmost occurrence of the species in the Indo-Pacific Ocean. The species is characterized by having a dark spot between first and third dorsal spines, branched orbital cirrus, and lacking nape cirri. A new Korean name, "Geom-eun-jeom-be-do-ra-chi" is proposed for the species.
