The tribe Cyllodini is reviewed as 10 species of three genera from Korea, including two new species Pallodes sp. nov. and Cyllodes sp. nov. and one newly recorded species Neopallodes vicinus Grouvelle 1892. A key to species from Korea, comments on external and genital structures, biology, illustrations of structures, including the genitalia of both male and female of the Korean Cyllodini species are provided.

Bombyx mandarina (Lepidoptera: Bombycidae) is generally regarded as the ancestor of the domesticated B. mori. Recently, over 40 mitochondrial genomes (mitogenomes) mainly from B. mori strains preserved in China and wild individuals of B. mandarina were sequenced to verify the progenitor of B. mori. At this point, we also were curious about the origin and the relationships of Korean silkworms to foreign B. mandarina and B. mori. As a first step, we sequenced the complete mitogenome of the B. mandarina collected in Korea and compared it to pre-exsiting data (37 strains of B. mori and 14 individuals of B. mandarina). The complete mitogenome of B. mandarina was 15,694-bp long, consisted of 13 protein-coding genes, two rRNA genes, 22 tRNA genes and one non-coding region. The 494-bp long A+T-rich region possessed the highest A/T content (95.3%) than any other region of the genome. Overall, the general mitogenome characteristics of the genus Bombyx species have an identical gene arrangement, similar A/ T content (average 82.3%) and so on. Phylogenetic analysis, however, showed that B. mori and B. mandarina formed a distant group each with the highest nodal support. For more findings of mitogenome characteristics of Bombyx including the Korean B. mandarina and those preserved in Korea more mitogenomes, particularly from Korea, might be needed.

The genus Diadegma is a well-known parasitoid group and some are known to have symbiotic virus so called polydnavirus (PDV, more specifically Ichnovirus, IV). The presence of the IV in the Diadegma species a has already been identified more than a decade ago. Previously we reported a DfIV, 62 genomic segments, 247kb from D. fenestrale which parasitized wide range of lepidopteran species (Generalist). However, DsIV from D. semiclausum which parasitized in the P. xylostella (Specialist) has 48 genomic segments, 208kb. Finally, 123 ORFs were re-annotated (repeat element protein, 41; cysteine motif protein, 11; viral innexin, 6; viral ankyrin, 8; polar residue rich protein, 7; N gene, 3; Neuromodulin protein, 2 and not assigned gene, 45). DsIV also have most of lepidopteran immunosuppression gene families and 103 ORFs annotated (repeat element protein, 36; cysteine motif protein, 8; viral innexin, 7; viral ankyrin, 6; polar residue rich protein, 7; N gene, 3; and not assigned gene, 36). Certainly, although viral species specific segments exists, two IVs showed high similarity in most of segments. However DfIV have some more number of that genes such as cysteine motif protein and viral ankyrin. Two Diadegma species also showed difference in mitochondrial genome structure. Therefore we concluded that two species has their own evolutionary linage depending on the lepidopteran hosts with its own symbiotic virus.

Residual contact vial (RCV) method was used to monitor insecticide resistance in field populations of the melon thrips, Thrips palmi. Median lethal doses (LD50) at 8 h post-treatment of six insecticides (chlorfenapyr, cyantraniliprole, cypermethrin, dinotefuran, emamectin benzoate and spinosad), which are commonly used for T. palmi control, were determined at 8 h post-treatment using a susceptible RDA strain. The diagnostic doses for on-site resistance monitoring of the six insecticides, which were determined as two-fold higher doses of LD90 for the RDA strain, were in the range of 0.299 to 164,25 μg-1cm2. To test the applicability of RCV for T. palmi, insecticide resistance levels in three field populations (Gyeonggi; GG_AS, Chungbuk; CB_CJ, Jeonbuk; JB_KJ) were evaluated. Field populations showed reduced mortality (0-50% mortality) to spinosad, cypermethrin, cyantraniliprole and emamectin benzoate, that they have different degree of resistances to these insecticides. In particular, all test field populations exhibited 0% mortality to spinosad, suggesting wide spread of spinosad resistance in the field. Moreover, no detectable mortality to emamectin benzoate was observed in JB_KJ strain, suggesting uneven distribution of emamectin benzoate resistant population of T. palmi. To provide more precise information on resistance profiles and distribution in T. palmi populations, it would be necessary to conduct a large scale resistance mapping for broad geographical regions.

Avermectin produced by Streptomyces avermitilis is an anti-nematodal agent against the pine wood nematode Bursaphelenchus xylophilus. However, its potential usage is limited by its poor water solubility. For this reason, continuous efforts are underway to produce new derivatives that are more water soluble. Glycosylation is generally used to enhance the aqueous solubility and biological activity of natural compounds. Uridine diphosphate (UDP)-glycosyltransferase (BLC) from Bacillus licheniformis is involved in the biosynthesis of the bioactive compound by transferring UDP-activated sugar moieties to acceptor molecules. Here, the enzymatic glycosylation of avermectin was catalyzed by uridine diphosphate (UDP) glycosyltransferase from Bacillus licheniformis with various UDP-sugars. As a result, the following four avermectin B1a glycosides were produced: avermectin B1a 4’’-β-D-glucoside, avermectin B1a 4’’-β-D-galactoside, avermectin B1a 4’’-β-L-fucoside and avermectin B1a 4’’-β-2-deoxy-D-glucoside. The avermectin B1a glycosides were structurally analyzed based on HR-ESIMS, 1D and 2D nuclear magnetic resonance (NMR) spectra. The solubility of avermectin B1a4’’-β-D-glucoside and avermectin B1a4’’-β-D-galactoside in water are 49 and 21 times higher than that of avermectin B1a. Consistent with the improved water solubility of avermectin glycosides, the anti-nematodal effect of avermectin B1a4’’-β-D-glucoside was found to exhibit the highest activity,which was approximately 32 times greater than that of avermectin B1a, followed by avermectin B1a 4’’-β-2-deoxy-D-glucoside, avermectin B1a 4’’-β-L-fucoside, and avermectin B1a 4’’-β-D-galactoside. These results show that glycosylation of avermectinB1a effectively enhances itsin vitro anti-nematodal activity and that avermectin glycosides can be further applied for treating infestations of the pine wood nematode B. xylophilus.

It has been reported that gastrocnemius tightness and posterior talar glide are crucial factors influencing ankle dorsiflexion. However, the relationship of ankle dorsiflexion and these factors is not identified in previous studies. The purpose of this study was to identify the relationship of ankle dorsiflexion passive range of motion and gastrocnemius tightness and posterior talar glide. Twenty-five male subjects participated in this study. Bilateral weight-bearing ankle dorsiflexion passive range of motion and amount posterior talar glide of participants were measured using an inclinometer. Change in myotendinous junction of medial gastrocnemius was measured using ultrasonography to identify gastrocnemius tightness. Pearson product moment correlations were performed to examine correlations between ankle dorsiflexion passive range of motion and gastrocnemius tightness and posterior talar glide. Present findings revealed significant correlation between ankle dorsiflexion passive range of motion and gastrocnemius tightness (p=0.017, r=0.336). Also, ankle dorsiflexion passive range of motion was correlated with posterior talar glide (p=0.001, r=0.470). The present findings provide experimental evidence for factors influencing weight-bearing ankle dorsiflexion.

Samples were collected from planktonic habitats of the fresh and brackish waters in Korea from August 2016 to May 2018. As a result, three genera and nine species were newly recorded in Korea. The unrecorded indigenous genera were Anathece, Chondrocystis and Geminocystis, and nine species were Anabaenopsis arnoldii, Anathece smithii, Chondrocystis dermochroa, Coelosphaerium aerugineum, Eucapsis microscopica, Geminocystis herdmanii, Microcystis panniformis, Synechococcus nidulans and Woronichinia karelica. Anathece smithii, Coelosphaerium aerugineum, Eucapsis microscopica, Microcystis panniformis and Synechococcus nidulans had been reported to inhabit freshwater, but these were found in brackish water in this study. Microcystis panniformis, which is a potential genus for causing green-tide, is taxonomically valuable in Korea.

Samples were collected from benthic and subaerophytic habitats of fresh and brackish water in Korea from April 2017 to April 2018. Accordingly, three genera and seven species were newly recorded in Korea. Three unrecorded genera were Cephalothrix, Cyanophanon and Toxifilum, and seven species were Anagnostidinema pseudacutissimum, Calothrix elenkinii, Cephalothrix komarekiana, Cyanophanon mirabile, Cyanosarcina chroococcoides, Leptolyngbya ectocarpi and Toxifilum mysidocida. Anagnostidinema pseudacutissimum and Cephalothrix komarekiana had been previously reported to inhabit freshwater, but these were found to be present in brackish water during the period of the present study. Also, Cyanosarcina chroococcoides previously reported to inhabit moorland waters and swamps, were found to be present in subaerophytic habitat.

Six taxa of unrecorded Korean species of charophytes are described. Freshwater and aerial charophytes were collected from the bark of trees, reservoirs, small ponds and swamps from April 2017 to September 2017. The newly recorded species of Korea were Cosmarium quadrifarium f. octastichum, Euastrum turneri, Spondylosium nitens var. triangulare, Staurastrum kouwetsii, Staurodesmus dickiei var. latus, and Klebsormidium subtile. K. subtile was transferred from Stichococcus subtilis.

In 2017, the freshwater algae were collected from reservoirs, small ponds, soil, and rocks in Korea. Eight taxa of Chlorophyta (Chlorophyceae and Trebouxiophyceae) have been newly reported in Korea. The unrecorded indigenous species were Chlorolobion braunii, Coelastrum pseudomicroporum, Coelastrum reticulatum var. cubanum, Monoraphidium nanum, Tetrachlorella incerta, Ecdysichlamys obliqua, Gloeotila scopulina, and Stichococcus jenerensis.

Phytoplanktons were collected from various environments including small marshes, small ponds, reservoirs and brackish water from March 2017 to November 2017. In this study, five species of family Scenedesmaceae were newly recorded in Korea. The genus Desmodesmus was newly reported in Korea. The newly recorded species are Scenedesmus nanus, S. praetervisus, Desmodesmus costato-granulatus, D. lunatus and D. spinulatus. S. nanus and S. praetervisus are known to occur in freshwater, but they were found in the brackish water in this study.

There exists very little information on the ultrastructure of substance P immunopositive (+) fibers in the human dental pulp, which may help in understanding the mechanism for substance P associated pulpal inflammatory pain. To address this issue, we investigated the presence of substance P+ fibers in the human dental pulp by light- and electron-microscopic immunohistochemistry. Light microscopy revealed that substance P+ fibers ran within neurovascular bundles in the radicular pulp and in the core of coronal pulp. They were also frequently present in the peripheral pulp. Substance P+ fibers showed beads like swellings interconnected by thin axonal strand, in a manner similar to bouton en passants and interconnecting axonal strand in the spinal cord. Electron microscopy revealed that almost all the substance P+ axons were unmyelinated. The axonal swellings of the substance P+ contained numerous clear round vesicles (40-50 nm in diameter) and many large dense-cored vesicles (80-110 nm in diameter) as well as many mitochondria. The vesicles and mitochondria were rarely observed in the thin axonal strand interconnecting the swellings. Intimate interrelationship or synaptic structure between the swellings of substance P+ axon and nearby pulpal cells or axons was not found. These findings suggest co-release of substance P and glutamate from the substance P+ pulpal axons and its action on nearby structures in a paracrine manner.

Pleurotus eryngii is one of the most commercially important mushrooms cultivated in Korea. However, the shelf-life of the fruiting body is short, limiting its export. A new hybrid strain H17 of P. eryngii was developed to extend the shelf-life by mono-mono crossing between monokaryotic strains derived from DanBi and KNR2774. Although the cultivation period of H17 was slightly longer than that of the reference cultivar Kenneutari No.2, the quality did not change and remained normal after a period of 65.0 days at 4°C. This result was significantly different from that of the reference cultivar Kenneutari No.2. Analysis of the genetic characteristics of the new hybrid strain H17 revealed a different profile from that of the parental and reference cultivars when random amplification of polymorphic DNA (RAPD) primers was used. These results demonstrate that H17 is a new cultivar with improved storability after harvesting.

Landscape performance is an assessment tool to quantitatively evaluate designed landscapes, which allows us to overcome the limitations of qualitative evaluation of ecological restoration projects. The purpose of this study was to develop a landscape performance assessment framework for ecological restoration using systematic reviews. To do this, literature related to landscape performance was systematically reviewed, considering the design intent of an ecological restoration project. Results indicated that the ecological benefits of ‘Water’and ‘Habitats’, the social benefits of ‘Recreational and Social Value’, and the economic benefits of ‘Operation and Maintenance Savings’should be considered first. Based on the results, this study suggests the landscape performance framework for ecological restoration projects. The landscape performance assessment framework can not only develop improvement plans for one ecological restoration project, but also potentially provide a logical basis for assessing other designed landscapes.

Free-standing electrodes of CuO nanorods in carbon nanotubes (CNTs) are developed by synthesizing porous CuO nanorods throughout CNT webs. The electrochemical performance of the free-standing electrodes is evaluated for their use in flexible lithium ion batteries (LIBs). The electrodes comprising CuO@CNT nanocomposites (NCs) were characterized by charge-discharge testing, cyclic voltammetry, and impedance measurement. These structures are capable of accommodating a high number of lithium ions as well as increasing stability; thus, an increase of capacity in long-term cycling and a good rate capability is achieved. We demonstrate a simple process of fabricating free-standing electrodes of CuO@ CNT NCs that can be utilized in flexible LIBs with high performance in terms of capacity and cycling stability.

Immersive Virtual Environment Technology (IVET) has emerged as a relevant technology in the marketing environment, with increased use in the retail context (O’Brien, 2016). As its use increases, there is a need to better understand its impact on consumer behavior and the experience that it delivers. Therefore, this study proposes a research model that captures the key constructs in understanding consumer acceptance behavior of the innovative technology used in marketing and how it impacts the brand experience. The objective of this study is to examine 1) antecedents (i.e., message fit and personal innovativeness) that may impact user’s attitude toward the IVET advertisement and self-image congruence, and 2) the transfer of positive or negative IVET advertisement attitude to behavioral intention. Survey was distributed at a large Southern university in USA. Out of 213 survey completed, 143 was usable. Hypotheses were tested using the structural equation model (SEM) analysis with maximum likelihood method (AMOS 23). The results showed that message fit had no significant impact on ad attitude and self-image congruence. Personal innovativeness had positive impact on ad attitude, but not on self-image congruence. Ad attitude had no effect on self-image congruence while having significant positive impact on offline store and online store visit intentions. Lastly, self-image congruence influences both offline and online store visit intentions. The results demonstrate that evaluation of the virtual world brand experience (i.e., attitude toward the IVET advertisement) is a strong predictor of user behavior toward the brand. A consumer’s interactions with a brand in the virtual environment may provide important information about the consumer’s desire to develop a relationship with the brand in other marketing channels, and serves as an opportunity for the marketer to assist in the buying process. Further, personal characteristic such as personal innovativeness may have a significant impact on a their attitude toward the IVET marketing which further leads to consumer’s decision to visit the online and offline store. In addition, self-image congruence were found to positively affect user’s intention to visit the stores, such that consumers who perceive their brand experience as more consistent with their self-image are more likely to consider purchasing the brand in the real world. The results suggest that some consumers may tend to behave in ways that are congruent with their self-identity across marketing channels.

The present study applies asymmetric analysis and models complex antecedent conditions to identify shoppers with high purchase intentions to sustainable fashion products’ (SFPs) and high eWOM intention. The fuzzy-set qualitative comparative analysis (fsQCA) method was used to assess the cause-and effect process. The examination was based on information process, and decision making of consumers in two countries (China and Korea) was found to vary by nationality. Specifically, consumers in the two countries provided different responses on sustainable fashion change configuration, suggesting differences in the characteristics of sustainable and non-sustainable fashion consumers and sustainable fashion intentions. The results show that various casual recipes on sustainable fashion change the configuration and sustainable fashion intention on corners 1 and 4. Both Chinese and Korean consumers do not have several unique demographic and fashion expenditure configurations that characterize consumers with high intention to buy and eWOM intention favorable toward sustainable fashion. In the Chinese consumers’ data, computing with words (CWW) showed that young•married•low-income•low-education•low-fashionexpenditure cases (consumers) were lower on negation purchase and eWOM intentions (i.e., an accurate screening configuration identifying consumers high io non-sustainable fashion intentions). The results also help identify consumer characteristics of sustainable fashion consumers and non-sustainable fashion consumers. Specifically, the results of the fsQCA suggest dissimilar confirmation to achieve purchase intention and eWOM intention of sustainable fashion and provide meaningful academic and managerial implications. The results of the fuzzy-set qualitative comparative analysis also support and clarify the role of the theory of information process and the theory of reasoned action towards sustainable fashion.

Introduction The fashion business is known as one of the major industries that is suffering from rising concerns about the consumption of its product, which led to a reorganization of the fashion supply chain to become more sustainable three decades ago. The interest in the concept of sustainability and demand for sustainable marketing activities is gradually growing in the fashion industry due to the negative image and press it receives. Within the luxury fashion segment, the three main themes that are recognized to contribute to sustainability are exclusivity, craftmanship and limited production. However, luxury brands are increasingly shifting their attention and commitment towards environmental and social issues to be incorporated in the concept of sustainability. Yet, the majority of consumers has little understanding or misunderstands the concept of sustainable fashion and marketing, which leads to a gap between attitudes towards sustainability and actual behavior. As a result, fashion brands are trying to leverage their brand by making sustainability a key marketing strategy to raise awareness about social, environmental, economic and cultural issues. Extant research has not explored this recent trend to understand how consumers evaluate fashion brands with a sustainable marketing communication, especially in the context of luxury brands. This study investigates how luxury and mass fashion brands can utilize sustainable marketing contents in social media communication to reach their target group and enhance their equity with sustainability associations. Theoretical Development Associative network models of memory have served as a fundamental framework for a wide range of studies related to the formation and transfer of associations. According to associative network theory, brand knowledge is represented in form of an associative network of memory nodes connected to each other. Nodes are activated when cues, such as advertising, are presented. Mere exposure to cues was shown to be sufficient to active associations and facilitate association transfer. While brands are continuously attempting to make use of associative power to leverage brand equity, extant research has provided compelling reasons to accept that association transfer can also result in brand dilution when a retrieval of conflicting or negative associations occurs. Especially in the context of luxury brands consisting of very unique associations and being different from mass brands in many regards, managing the brand’s associative network is a crucial task in order to send the right signals to consumers and maintain exclusivity. This study investigates how social media communication of different sustainability dimensions affects brand attitude and how it ultimately impacts behavioral outcomes in an attempt to build brand equity for mass and luxury fashion brands. Method and Data The hypotheses are tested with 273 respondents who participated in an online experiment. They were first asked to state their involvement with the category fashion. Subsequently, subjects were presented with a brand post either for the mass or luxury brand including claims related to one of the four sustainability dimensions or no claims for the control group respectively. The experiment consisted of a 2 (brand: mass or luxury) x 5 (sustainability dimensions: none, cultural, economic, environmental, social) factorial design. The measures that followed included attitudinal as well as behavioral constructs related to the brand, sustainability as well as social media use. Analysis of covariance is applied to test for main effects and interaction effects. Summary of Findings This study provides evidence that social media communication of a sustainable brand affects the purchase intention of consumers. The findings indicate a significant difference between the mass and the luxury brand used for this study. The mass brand exhibits the potential to leverage associations with cultural, economic, and environmental sustainability. However, the results only reveal a marginally significant higher purchase intention when cultural sustainability is communicated compared to when the brand does not provide any sustainable associations. In contrast, the luxury brand suffers from significant brand dilution across all four sustainability dimensions resulting in a decline in purchase intention. Key Contributions The findings reveal that sustainability communication exerts a diverging influence depending on the type of brand that is involved. This study suggests that mass brands are able to benefit from sustainability communication in an attempt to leverage brand equity. However, for a luxury brand this type of associations rather presents a liability that might dilute the brand. The findings of this study provide important insights for brand managers. Since mass brands are currently increasing efforts into sustainable communication in the fashion industry, the results suggest that this might be a promising investment. However, luxury brands are advised to carefully manage the communication of salient content related to sustainability as it might harm the invaluable and unique associations inherent in a luxury brand.

This study aims to gain insights into consumers’ motivations when purchasing mimics of luxury cosmetics goods and their evaluation towards mimicry products. Consumers’ desire for mimicry luxury cosmetics hinges on their motivations underlying their consumption of luxury cosmetics. Attitude functions are applied to measure consumers’ underlying motivations towards luxury products. Consumers’ attitude and familiarity with luxury cosmetics and mimicry cosmetics also influence their choice between luxury brands and mimicry brands. In addition, consumers’ personality factors and perceived risk of purchasing mimicry cosmetics and their brand loyalty towards the original luxury brands restrain their purchase intention of mimicry brands. Finally, the study examines the effect of products conspicuousness (private/public visible goods) and the effect of mimicry types (feature/theme) on consumers’ preferences on concerning mimicry consumption. The findings will provide insights for policymakers, brand managers, and academics, and better understand mimicry in the luxury cosmetics industry.

Following the 2008 financial crisis, globalized markets in North America and Europe experience a shift in public opinion toward a renunciation of globalization and a reorientation toward traditional (domestic) values. Responding to this paradigm change, multi-national corporations (MNCs) face the decision of whether (a) to continue to pursue global branding strategies or (b) to align their global brands with local consumer cultures. This decision requires an understanding of how the degree of market globalization relates to consumer preferences. The present study draws on signaling theory to empirically investigate (a) the relative impact of a brand’s globalness (i.e., perceived brand globalness) and its cultural market alignment (i.e., perceived cultural symbolism) in eliciting perceptions of brand credibility and brand quality (b) across two countries that differ regarding their degree of market globalization (Germany and South Korea). Findings indicate that the signaling value of global brands, as a function of their market reach, is greater in globalizing markets than in globalized markets, whereas the signaling value associated with cultural market alignment is greater in globalized markets than in globalizing markets. Implications of the findings for theory and practice are considered.
