We report one newly recorded species Warreniplema fumicosta (Warren) for the first time in Korea. In July, a single female specimen of Warreniplema fumicosta was collected at a high altitude on Mount Jirisan. This species can be distinguished by the light blackish forewing with the largely undulating ante- and postmedial lines, and the bicolorous hindwing with yellowish upper half dark brown lower half, and dark brown ante- and postmedial lines. So far, there have been 13 species belonging to seven genera of the Epipleminae subfamily that have been documented, and this includes W. fumicosta.

본고는 표준기록관리시스템과는 차별화하여, 전자결재시스템과 기록관리시스템을 하나의 시스템으로 운영하고, 기록관리 보조도구로 인공지능, 챗봇 등의 지능형서비스를 접목한 한국중부발전의 기록관리시스템 구축을 위한 준비과정을 소개함을 목적으로 한다. 기록관리 전 생애주기를 관리하는 것은 물론이고, 현용기록의 활용성을 높이기 위한 실시간 이관 및 기능분류체계 활용에 대해 심도있게 검토하여 설계하였으며, 폭증하는 전자기록물의 효율적 관리를 위하여 인공지능 등 신기술을 도입하였다. 기록관리행위의 첫 단추이자 가장 중요한 시작인 분류의 정확성을 높이고자, 기계학습을 통한 기록물분류를 추천하여 처리과에서의 무분별한 오분류를 사전에 차단했으며, 업무관련 규정 및 기록의 활용을 위하여 챗봇을 도입하는 등 기록관리 분야에서 신기술을 적극 도입하였다. 또한 시스템 간 이관에 따라 생기는 열람권한 문제를 전자결재시스템 및 기록관리시스템의 열람권한을 모두 확인하여 권한을 부여하는 등 기록물의 적극적 활용을 위해 많은 노력을 하였다.

We describe the morphological characteristics of two morids, Gadella jordani and Physiculus japonicus, belonging to the order Gadiformes, based on Korean specimens collected from the Korean ocean. Two specimens of Gadella jordani was first collected from Jeju Island, Korea and the East Sea, Korea, in 2013-2014. This species is characterized by 8, 67-69 dorsal fin rays, 66-71 anal fin rays, 5+13 gill rakers, no barbel on the lower jaw, no vomerine teeth, and a ventral luminous organ closer to the anus than to the interventral line. We described it as the first record to the Korean fish fauna, and proposed the new Korean name "Min-su-yeom-dae-gu-sok" for the genus Gadella, and "Min-su-yeom-dae-gu" for the species G. jordani. Physiculus japonicus was first reported by Koh and Moon in the year 1999 based on a single specimen in Korea. However, no study has been attempted to describe the morphological characteristics in Korea since then. In 2013-2014, three specimens of P. japonicus was collected from Jeju Island, Korea and the East Sea, Korea, and we redescribe P. japonicus in detail. This species is characterized by 9-10, 63-64 dorsal fin rays, 70-73 anal fin rays, 3+7-8 gill rakers, a short barbel on the lower jaw, and a ventral luminous organ equidistant between the interventral line and the anus.

A new species of the Cletopsyllidae belonging to the genus Isocletopsyllus Huys and Lee, 1999 is described from the materials collected from subtidal sandy bottoms at Jeju Island and Ulleung Island, Korea. So far, only two species of the genus Isocletopsyllus, viz. I. tertius (Por, 1964) from Israel and I. quartus (Soyer, 1966) from Banyuls-sur-Mer (France) are recorded, both from the Mediterranean Ocean. The new species can be clearly distinguished from its congeners by the combination of the following characters: (1) female antennule with a large process on the outer margin of first segment, (2) caudal rami with a bulbous proximal inner expansion, and shorter than those of other species (about four times long as wide in the new species), (3) second segment of P1 exopod with a short rod-like inner seta, (4) sexual dimorphism presented in the second endopodal segment of male P2, not in exopod of P4, and (6) female P5 with a very long exopod with very short second outer seta. A table comparing the modifications of swimming legs in the family Cletopsyllidae Huys and Lee, 1999 is presented. This is the first record of this family from Korea.

Herein, we report a new record of Arna bipunctapex (Hampson) and a new species, Euproctis fulvatus sp. nov. in Korea; both are Lymantriine moths. Arna bipunctapex is distinguished by a relatively large wingspan with two black dots and a small dot between these black dots in the apical region of a yellowish forewing. The male genitalia of A. bipunctapex can be distinguished by the lack of a process on the sacculus of valva while the female genitalia can be distinguished by an antrum that is basally flat with two lateral digitate arms. Euproctis fulvatus is distinguished by yellowish wings with a medially curved central fascia of the forewing. The male genitalia can be distinguished by the bifid, digitate uncus and the simple, square-shaped valva with a distal strong invaginated margin. The female genitalia can be distinguished by the long, medially twisted, ductus dursae with simple antrum posteriorly strongly sclerotized and ovate corpus bursae without signum. Larvae of E. fulvatus are distinguished by a black head with a pair of long, black, lateral tufts, dorsum with 10-11 white intersegmental dots and bright red setal warts on T2-A8, and bright red glands on A6 and A7.

Neoporphyra kitoi Ma. Abe, N. Kikuchi, Tamaki, Tom. Sato, Murase, Fujiyoshi & Mas. Kobayashi has been known as an endemic species in Japan. Its high temperature tolerance suggests that it could be advantageous for cultivation. In this study, we collected it from the Ulleungdo island, Korea and transferred it into Pyropia for a new combination, identified as Pyropia kitoi(Ma. Abe, N. Kikuchi, Tamaki, Tom. Sato, Murase, Fujiyoshi & Mas. Kobayashi) D.J. Kim, T.O. Cho & B.Y. Won comb. nov. based on morphological and molecular analyses. Pyropia kitoi is also reported as a new record species in the list of Korean macroalgal flora. Although we didn't observe the emergence of new blades from the rhizoidal cells, which is a key character for this species, our molecular analysis of rbcL revealed that our samples from Korea were congruent with "Neoporphyra kitoi" from Japan and were nested within the clade of Pyropia. The gene sequence divergence between the Korean and Japanese samples was 0-0.2%.

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.

To investigate the effects of haunch repair on the system seismic performance of steel moment-resisting frames (steel MRFs), a case study was conducted for a 13-story frame damaged during the 1994 Northridge earthquake. It was assumed that only those locations with reported damage would be repaired with haunches. A new analytical modeling technique for the dual panel zone developed by the author was incorporated in the analysis. Both the inelastic static and dynamic analyses did not indicate detrimental side effects resulting from the repair. As a result of the increased strength in dual panel zones, yielding in these locations were eliminated and larger plastic rotation demand occurred in the beams next to the shallow end of the haunches. Nevertheless, the beam plastic rotation demand produced by the Sylmar record of 1994 Northridge earthquake was still limited to 1.7% radians. The repair resulted in a minor increase in earthquake energy input. In the original structure, the panel zones should dissipate about 80%(for the Oxnard record) and 70%(for the Sylmar record) of the absorbed energy, assuming no brittle failure of moment connections. After repair, the energy dissipated in the panel zones and beams were about equal.

기록관리 분야가 정보화 환경을 맞게 되면서 자체기준에 의하여 제반업무를 수행하던 방식은 좀 더 종합적인 사고가 필요하게 되었다. 기록을 정보로 활용하고 정보를 기록으로 보려는 상호연동적인 시각이 나타나며, 나아가서 기록을 생산할 때부터 정보환경에서 활용하게 될 것을 고려하고 정보시스템에서는 관리중인 정보자료의 기록가치를 고려하게 될 것이다. 현재까지는 기록을 잘 생산시켜 잘 이관시키고 잘 보존시키는 것에 초점이 맞추어져 있었기 때문에 관련 법령이나 업무지침, 연구교육이 이를 중심으로 이루어져 왔다. 앞으로는 보존 이후의 단계, 즉 공개, 공유, 사본제작, 정보보호, 시스템 연계, 기록컬렉션 사후보충 등 일반인에 대한 정보서비스가 강화되어야 할 것이다. 본 논문에서는 최근의 보도사건을 통하여 기록과 정보간의 혼란을 살펴보고 이들의 융합이 필요함을 설명하며, 기록관리 시스템과 정보시스템 상호간의 환류체계를 제안한다.

본 연구의 목적은 LP 산업의 구조를 분석하여 해당 산업의 매력도를 이해하고 시사점을 도출하는 것에 있다. 선행연구는 급증한 LP 수요에 주목하며 소비자 관점에서 해당 소비와 LP 산업을 이해하였으나, 본 연구는 LP의 생산 및 유통의 주체에 초점을 맞추어 진행하였다. 본 논문은 LP 산업 내 현업종사자들과 심층면접 및 다양한 이차자료를 통해 자료를 수집하고, 이를 포터(1980/2008)의 5요인 이론(Five Forces model)으로 분석하였다. 분석결과, LP 산업의 매력도는 산업 내 경쟁 강도가 적정하고 구매자의 교섭력이 약하다는 측면에서는 긍정적이지만, 신규 진입자와 대체재의 위협 및 공급자의 교섭력이 강하다는 측면에서 부정적이다. 이는 LP 산업에 신규 진입하려는 기업들의 전략적 판단을 위한 기초자료로서의 의의가 있다.
