  • Because Ceramium fastigiatum Harvey (1834) is a later homonym of C. fastigiatum Roth (1806), a quite different plant from the former, it becomes illegitimate and must be rejected under the Article 64 of International Code of Botanical Nomenclature. For this reason, we suggest to give a new name, Ceramium fastigiramosum Boo et Lee, to the former species, keeping the original specific epithet‘fastigiatum’. The morphology of vegetative and reproductive structures is re-examined. The life history is confirmed as a Polysiphonia-type in laboratory culture.

Revealing "difference" for Space of Hope: A Comparative Study of Harvey and Gibson-Graham on Spatiality of Capitalism (희망의 공간을 만들기 위한 "차이" 드러내기: 자본주의 공간성에 대한 Harvey와 Gibson-Graham 비교 연구)

  • For a shift to a new paradigm that allows restoring solidarity among class, gender, and race, it is necessary to closely investigate the differences between Marxist view and poststructuralist view which provide theoretical basis for labor movement and for feminist movement, respectively. However, little effort has been devoted to this task. This paper critically compares two best wellknown geographers; Harvey's class-centered theory and Gibson-Graham's post-structuralist feminist approach by focusing on their understandings of "difference". David Harvey argues that racial/gender discrimination is another form of class-exploitation and puts priority on the solidarity based on the commonality of labor. On the contrary Gibson-Graham argues that the privileging of class above all else marginalizes other political dimension, and proposes the deconstruction of hegemonic discourse of capitalism and the construction of "community economies", Based on the critical survey of both theories, I propose that understanding the role that spatiality plays in capital accumulation process is the key to compromise two different approaches.

  • Polysiphonia senticulosa Harvey (Ceramiales: Rhodophyta) was recorded for the first time in Korea, and its vegetative and tetrasporangial morphologies are described. This species is characterized by the combined features of having a vegetative axial segment with 4 pericentral cells, a main axis without cortication, pseudodichotomous branching, branches with sharply pointed apical cells, flexuous branches hooked backward below, the presence of cicatrigenous branches, axillary endogenous stichidia, and the production of 1-3 tetrasporangia per stichidium. Based on this study, it is distinguished from Polysiphonia morrowii Harvey by its flexuous branches and the number of tetrasporangia produced per stichidium.

  • This study was performed to investigate the change of chemical components and antioxidant activities in Hizikia fusiformis(Harvey) OKAMURA with blanching times. For chemical composition, the contents of minerals (K, Ca, Na, Mg, Fe, Cu, Mn and Zn), vitamins (vitamin C, ${\beta}$-carotene and ${\alpha}$-tocopherol) and total polyphenol were analyzed. The antioxidant activity was determined through free radicals (DPPH radical, superoxide anion radical, hydroxyl radical and hydrogen peroxide) scavenging activity and linoleic acid peroxidation inhibitory activity. As the blanching time increased, the contents of all minerals, vitamin C and total polyphenol decreased. However ${\beta}$-carotene and ${\beta}$-tocopherol were not affected by the blanching time. In addition antioxidant activities decreased with increasing blanching time.

  • In this study, we evaluated the effects of harvey powder on the fernentation of Yulmoo Kimchi, by measuring sensory, physicochemical, and microbiological properties during fermentation up to 31 days. The Yulmoo Kimchi, with various levels [0, 0.1, 0.2, 0.3, 0.4% (w/w)] of harvey powder, was fermented at $10^{\circ}C$. The product containing the control evidenced the highest scores for appearance and smell. Taste, carbonated taste, texture and overall acceptability were highest in the 0.1% harvey powder and control. During fermentation, titratable acidity increased while pH gradually decreased. Reducing sugar showed no difference at initial fermentation and then steadily decreased. Total vitamin C was gradually decreased during fermentation and reduced sharply after 10 days, and then almost maintained. Total polyphenol content was the highest in the 0.3% harvey powder on day 0 and maintained in all samples thereafter. Antioxidant effect of the Yulmoo Kimchi with 0.1% harvey powder was shown to be the highest. Also, the time required to achieve maximum levels of lactic acid bacteria, as determined by log numbers of cells and total viable cells, were more delayed in the experimental groups with added harvey powder than in the controls. Our results indicated that the Yulmoo Kimchii with below 0.1% added harvey powder was acceptable.

  • Historically the UK has been a pioneer and early adopter of experimental investigation techniques on new and operation structures, a technology that would now be descried as 'structural health monitoring' (SHM), yet few of these investigations have been enduring or carried out on the long span or tall structures that feature in flagship SHM applications in the Far East.

Morphology and Reproduction of Symphyocladia latiuscula (Harvey) Yamada (Rhodophyta, Rhodomelaceae) in Korea (한국산 홍조 참보라색우무(Symphyocladia latiuscula (Harvey) Yamada)의 형태와 생식)

  • The morphotaxonomic characters and life history of Symphyocladia latiuscula (Harvey) Yamada were investigated with field and laboratory culture materials. The species is well defined by a 5-15 cm hight, entirely corticated thallus and congenital fusion of 5-7 segments between main axis and laterals. Although all the reproductive structures are basically similar to those of other species of the genus, it is characteristic that the pinnulae are transformed into the flabellated tetrasporangial stichidia. Vegetative trichoblasts are known to be absent in the Pterosiphonieae, but their presence in S latiuscula does not accept its taxonomic position in that tribe. As a result, the occurrence of vegetative trichoblast is not useful for a taxonomic character to distinguish the tribes. The species shows a Polysiphonia-type life history involving a dimorphic alternation of gametophytes and sporophytes in culture and field. It grows below the middle intertidal zone in all the coasts of Korea throughout the year, although fertile plants are normally found during the summer months.months.
