  • Recently, the Fusarium genus has been narrowed based upon phylogenetic analyses and a Fusarium-like clade was adopted. The few species of the Fusarium-like clade were moved to new, re-installed or existing genera or provisionally retained as "Fusarium." Only a limited number of reference strains and DNA marker sequences are available for this clade and not much is known about its actual species diversity. Here, we report six strains, preserved by the Belgian fungal culture collection BCCM/IHEM as a Fusarium species, that belong to the Fusarium-like clade. They showed a slow growth and produced pionnotes, typical morphological characteristics of many Fusarium-like species. Multilocus sequencing with comparative sequence analyses in GenBank and phylogenetic analyses, using reference sequences of type material, confirmed that they were indeed member of the Fusarium-like clade. One strain was identified as "Fusarium" ciliatum whereas another strain was identified as Fusicolla merismoides. The four remaining strains were shown to represent a unique phylogenetic lineage in the Fusarium-like clade and were also found morphologically distinct from other members of the Fusarium-like clade. Based upon phylogenetic considerations, a new genus, Pseudofusicolla gen. nov., and a new species, Pseudofusicolla belgica sp. nov., were installed for this lineage. A formal description is provided in this study. Additional sampling will be required to gather isolates other than the historical strains presented in the present study as well as to further reveal the actual species diversity in the Fusarium-like clade.

  • Hemolymph is oxidized and darkens visibly during the collection from silkworm due to the activity of tyrosinase in it. Toxic quinones are produced by the oxidation and consequently inhibit the cell growth. Heat treatment can be used to prevent the oxidation ; however, the oxidation may occur during the collection of hemolymph before it is heat-treated. It makes the hemolymph collection difficult especially on a large-scale preparation. Hemolymphs collected from 257 different strains of silkworms were examined to select the slowly oxidized hemolymphs. Hemolymphs collected from mutant strains such as Lemone, TBO, Cre, Y4, and wEb showed relatively slow color changes. Oxidation rates of the hemolymphs were measured by the absorbance change using a spectrophotometer. The hemolymph of wEb showed the slowest oxidation. The absorbance of this mutant hemolymph reached the saturation value at 20$^{\circ}C$ in 450 min, whereas the total oxidation time of the wild-type (Baekokjam) hemolymph at the same temperature was 120 min. We tested if this mutant hemolymph is useful as a medium supplement for insect cell culture. Cell growth rate and final cell concentration in the medium supplemented with the wEb hemolymph were almost same as those in the medium supplemented with the wild-type hemolymph. Hemolymph is collected on a small scale by clipping the abdominal leg; however, this method is not appropriate fro large scale preparation. Centrifugation after chopping the silkworm hemolymph by a blending mixer is a more appropriate procedure for large scale collection. Slowly oxidized wEb hemolymph resulted in higher cell concentration than the wild-type hemolymph when hemolymph was collected by the large scale preparation method.

  • 전 세계적으로 기후 위기와 에너지 비용 증가 등의 문제로 인해 에너지 절감과 관리에 대한 관심이 증대되고 있다. 대한민국의 경우 전체 에너지 사용량의 약 53.5%가 산업 단지에서 사용하여 이와 관련한 에너지 절감 포인트를 찾고자 유사한 에너지 유틸리티를 사용하는 기업 간의 "공유 네트워크 유틸리티 플랜트"를 통해 문제점을 개선하고자 하였다. 이러한 에너지 절감을 위해서 활용하는 다양한 기법들과 공장의 안정적인 운영을 위해서는 데이터의 안정적 수급이 그 무엇보다 중요하다. 그를 위해 데이터를 안정적으로 수급할 수 있는지에 대해 알아볼 수 있는 이상 데이터 감지 시스템과 알림 시스템의 대다수는 에너지 관리 시스템에 종속되어 한계가 있었고 에너지 관리 시스템의 구축은 대단위 시스템의 구축으로 공간, 에너지적 한계가 있는 소형 공장에서 구축이 어려웠다. 본 논문에서는 문제점들을 극복하고자 적은 공간과 전력을 소비하는 임베디드 디바이스에 데이터 수집 시스템과 이상 데이터 감지 알림 시스템를 구축하고, 데이터 수집을 하는 보편적인 기관에서 이상 데이터 감지 알림 시스템의 활용 가능성과 구축 과정에 대한 연구를 수행하였다.

  • The purpose of this study is to analyze the fusion phenomenon that appears in contemporary women's denim fashion in order to find a way to come up with a creative denim design. The methodology of this study is to research documents related to fusion phenomena and consider precedent studies to establish a criteria for analyzing fusion phenomena. The results are as follows: First, fusion phenomena in modern women's denim can be categorized into fusion of time, fusion of space, fusion of gender, fusion of culture, and fusion of genre. Fusion of time appears as fusion with the past and fusion with the future. Fusion of space appears as fusion with Asia and fusion with other regions. Fusion of gender appears as unisex, androgynous, and genderless. Fusion of culture appears as fusion with subcultures such as grunge, kidult, lingerie, hippy look, hip hop fashion, etc. Finally, fusion of genre appears as fusion of materials, fusion of style, and fusion of circumstances. Second, when analyzing the frequency of appearance for fusion phenomena, fusion of culture appeared with a frequency of 29.7%, followed by fusion of genre with 19.1%, fusion of time with 10.5%, fusion of gender with 9.9%, and fusion of space with 8.5%. When analyzing the most frequently appearing fusion phenomena by year, fusion of culture appeared the most from the year 2000 to 2004, fusion of space and time in 2005, fusion of genre from 2006 to 2007, fusion of culture again in 2008 and 2009, and once more fusion of genre appeared the most in 2010.
