A survey of insect-associated fungi in Korea revealed a novel fungal strain isolated from the bean bug Riptortus clavatus (Heteroptera: Alydidae). Culturally and morphologically, the fungal strain designated KNUF-20-INY03, shares features with members of the genus Acaulium. Phylogenetic analyses based on the concatenated nucleotide sequences of the internal transcribed spacer regions (ITS) regions and partial sequences of the translation elongation factor 1-alpha (TEF1-α), and β-tubulin (β-TUB), and large subunit of the nuclear ribosomal RNA (LSU) genes showed that the isolate is part of a clade that includes other Acaulium species, but it occupies a distinct phylogenetic position. Based on the shape, size, and color of its conidia and conidiogenous cells, strain KNUF-20-INY03 is readily distinguishable from the closely related A. acremonium, A. albonigrescens, A. caviariformis, A. pannemaniae, and A. retardatum. The conidial length-to-width ratio (1.6) of the novel isolate is significantly lower than that of A. acremonium (1.9), A. albonigrescens (2.4), and A. pannemaniae (2.4), and KNUF-20-INY03 produces hyaline conidia and elliptical conidiogenous cells while A. caviariformis forms brown conidia and A. retardatum produces flask-shaped conidiogenous cells. Thus, both phylogenetic and morphological analyses indicate that this strain is a novel species in the genus Acaulium, and we propose the name Acaulium microspora sp. nov.

The present study investigated the effects of feed form and distiller's dried grain with solubles (DDGS) on meat quality and fatty acids profile of broiler chickens. A total of 720 broilers (Ross 308; average BW [body weight] $541{\pm}5.7g$) were randomly allotted to six treatments. Birds were fed three different feed forms (mash; SP, simple pellet; EP, expanded pellet) and DDGS (0 or $200g\;kg^{-1}$) in a $3{\times}2$ factorial arrangement. The addition of DDGS and EP to the diet resulted in increased shear force of breast meat. Moreover, DDGS inclusion in the diet reduced the concentration of stearic acid and behenic acid in thigh meat. Pelleting (SP and EP) of the diets increased palmitic acid content in the thigh, whereas the linolenic acid content decreased. The breast mass was higher with EP and SP diets than with the mash diet. Feed processing led to increased pectoralis muscle and drum mass compared to mash-fed chickens. In conclusion, our results demonstrated that EP decreased thigh linolenic acid and meat shear force. In addition, DDGS supplementation in broiler hampers meat quality by increasing the shear force.

Cyprinids are popular species for aquaculture worldwide, with Asia being a significant contributor to their production. In Korea, common carp (Cyprinus carpio), koi carp (Cyprinus rubrofuscus), and goldfish (Carassius auratus) are cultivated domestically and imported for ornamental or human consumption purposes. Among the viruses that infect cyprinids, cyprinid herpesvirus-2 (CyHV-2), koi herpesvirus (KHV, also known as cyprinid herpesvirus-3), and carp edema virus (CEV) are of particular concern as they cause substantial economic losses to the aquaculture industry. In this study, we investigated these viruses in both of domestic and imported cyprinids. Our results revealed that CyHV-2 was only detected in imported goldfish from Thailand. To further investigate the genetic characteristics of them, the marker A region was analyzed. Despite belonging to the same cluster with isolates from China, France, Poland, and Israel, CyHV-2 detected in this study showed distinct differences in their repetitive sequence sizes. Furthermore, two different forms of KHV/CEV coinfection were identified from domestic koi carp, both of which exhibited typical symptoms. Phylogenetic analysis showed that one KHV isolate (ScKc-2105-K) was of the Asian type and closely related to isolates from Japan, Indonesia, Belgium, Taiwan, and China. Two CEV isolates (ScKc-2105-CE and GhKc-2207-CE) be- longed to the IIa type and showed high similarity with isolates from the USA, France, and Korea. Notably, koi carp injected with cultured KHV (ScKc-2105-K) showed 78.0% cumulative mortality within 14 days post-injection (dpi). Our findings support the importance of regular surveillance of viral diseases in cyprinids.

This paper identifies trends in research methodology due to globalization. Context in both research and in practice and forms the key perspective for modern methodology and theory. Ecological perspectives are a necessary condition for quality global research. Human ecology researchers must advance the role of interdisciplinary and inter-functional perspectives and be open to collaborative relationships. These researchers must work in teams across disciplinary and functional boundaries. The paper discusses directions for research within the context of trends at U.S. federal agencies with applications to globalization and family life. Trends include： (a) use of diverse but rigorous methodologies； (b) recognition of the research-practice-research feedback loop；(c) primacy of context and diverse sampling; and (d) connections of research to problem solving. The terms promoted recently such as ″relationships″, ″diversity″ or ″problem-based″ are ingrained in human ecology. Key aspects for research in the next decade will be： (a) seeking diversity in sampling； (b) seeking colleagues with different perspectives； (c) incorporating meta-analysis into our work； (d) seeking meaningful results； (e) utilizing varieties of research methodologies to address our problems； and (0 understanding that practice must continually change as a function of research.

The obligate aerobic Deinococcus are highly resistant against lethal effect of UV-and ionizing-radiation. Only five mesophilic Deinococcus species, i. e. D. radiodurans, D. radiophilus, D. proteolyticus, D. radiopugnans, and D. grandis are known. Since an indispensable role of catalase has been suggested in protecting cells against oxidative stress and UV radiation, Deinococcal catalase activity of each species and electrophoretic profiles of catalases were investigated on gel. Total catalase activity was varied among the species in the aerobically grown culture at stationary phase. The occurrence of multiple forms of catalases with different molecular weights in four species of Deinococcus and of a single catalase in D. radiopugnans suggests that each species shows the unique catalase profiles on gel. Some Deinococcal catalases also exhibit peroxidase activity. Since Deinococcus spp. are less-distinct to each other in their morphology, biochemical and physiological properties, the catalase profiles on PAGE would be useful in identifying the species of Deinococcus.

It is well known that pipelines have the highest capacity and are the safest and least environmentally disruptive form of transporting oil and gas. However, pipeline damages caused by both internal and external corrosion is a major concern threatening the reliability of oil and gas transportation and the soundness of pipeline structure. In this study, we estimated the expected allowable damage defect by comparing the ASTM B31G code which has been developed as the evaluation method of reliability and incident prevention of damaged pipelines based on the amount of loss due to corrosion and the yield strength of materials to a modified theory considering diverse detailed corrosional forms. Furthermore, we suggested the method that estimates the expected life span of used pipelines by utilizing the reliability method based on major variables such as, the depth and length of damage and corrosional rate affecting the life expectancy of pipelines.

This study focuses on wardrobes to examine how the terms have been changed by comparing traditional Korean furniture in Chosun Dynasty and contemporary furniture since the traditional furniture terms and forms have been changed like our life culture. For chests and wardrobes, approximately 26 terms were used in Chosun Dynasty. However, only five of them are currently used for top panels, hinges, drawers, mirrors, and columns. For bedroom cabinets, 27 terms are used and 4 of them are changed with the same meaning. The change of the terminology results from the life culture mostly. While the Chosun Dynasty furniture terms were mostly presented as the Korean and Chinese language, in the contemporary furniture ones Korean and Chinese together with English are used. The English terms' usage results from hardwares imported from overseas. The terms derived from the three different languages are presented not only in the wardrobes but also other pieces generally.

This study deals with 'Sachlichkeit' , as essence of materiality that architectural building materials process, which forms the physical basis for actual building. There have beennu merous researches that deals with various elements that compose architecture, but the emphasis seemed to be concentrated on the meta-physical discussion concerning formal concept. An issue on sachlichkeit as materiality does not necessary mean to mention production process of architecture, rather it is aim of this study to seek possibility to find elements that generate architectural form, through interpreting meaning of materials as substructure generator to make architectural possible. Architectural act can be defined as a process where physical material in life is composed into architecture by the hands of architect. Material used in life is composed into architecture by the hands of architect. Material used in this process basically has neutral characteristic, so 'Sachlichkeit'solely depends on the intentions of architects. This study interprets the intention of architects through the frame of modern-basis proposed by Hilberseimer, and a result architecture is defined as an object projected by architect's subjectivity.

Redox-dependent conformational change of human 8-kDa Dynein light chain (LC8) plays important role in regulating NF-${\kappa}B$ signaling pathway. In this study we characterized the structural states of the oxidized and reduced forms of LC8 by using NMR spectroscopy. The $^1H-^{15}N$ 2D HSQC spectra of oxidized LC8 indicated that no significant change in tertiary structure of LC8 occurred upon oxidation. The chemical shift perturbations of LC8 upon oxidation suggest a redox-dependent quaternary structural change.
