        Individual safety is a fundamental concern. People generally try to avoid danger or mishaps in the workplace, and to consider safety as a primary condition for satisfactory employment and agreeable shopping experiences. Organizations can assure that workers, clients, the public, and the environment perceive that they are in safe environments by providing highly secure services. Secure working environments and safety-focused human resource environments are essential antecedents to safe performance and outcomes. Dangerous workplace environments cause employees to feel stress and anxiety. Thus their performance decreases and accidents and injuries increase. Workplace safety is the most important factor influencing service and performance, especially for allowing frontline salespersons to focus on providing customer satisfaction. In this study of workplace safety, we apply the service quality dimension to examine its relationship with employee perceptions of job satisfaction and their related job performance. We discuss theoretical and practical implications based on the results.

        Due to their environmental and economical consequences, invasive species have become a major concern worldwide. Among them, the yellow-legged hornet, Vespa velutina, is a keen hunter of domestic honeybees. They use olfactory cues from the prey to assess food information. In this study, we investigated the attraction behavior of V. velutina to honeybee pheromone under outdoor conditions. Nine honeybee pheromones were tested and compared in order to find the best attractant. When testing specific compounds, the honeybee queen pheromone, homovanillyl alcohol, proved highly attractive.

        The diamondback moth (DBM), Plutella xylostella, is a globally distributed and important economic pest. Chemical control is the primary approach to regulate populations of this pest. Chlorantraniliprole is the first commercial insecticide that belongs to the new chemical class of diamide insecticides. In this study, the resistant strain was observed 1578-fold resistance to chlorantraniliprole. Point mutation (G4946E) in ryanodine receptor (RyR) showed a high frequency. Enzyme assays indicated that glutathione S-transferase (GST) activity in the resistant strain was 2.4 times higher compared with the susceptible strain, whereas no difference was seen for P450 and esterase. In addition, the expression of two GSTs genes was up-regulated. These findings pave the way for the complete understanding of the mechanisms of diamide insecticides resistance in insects.

        The diamondback moth, Plutella xylostella, is known worldwide as a pest that affects cruciferous plants. We surveyed insecticide susceptibility in chlorantraniliprole-resistant strain of P. xylostella to 13 insecticides (3 diamaids, 2 synthetic pyrethroids, 2 spinosyns, 1 organophosphorus, 1 carbamate, 1 marcrolide, and 3 others) to examine resistance ratios. The levels of insecticide resistance were extremely high, especially to chlorantraniliprole and flubendiamide. Enzyme assays indicated that glutathione S-transferase (GST) activity in the resistant strain was 2.4 times higher compared with the susceptible strain, whereas no difference was seen for P450 and esterase. Its F1 progeny resulting from reciprocal crosses with a susceptible strain revealed no maternal effects and a diamide susceptible phenotype, suggesting an autosomally almost recessive mode of inheritance.

        Using current-voltage (I-V) and capacitance-voltage (C-V) measurements, the electrical properties of Au and Cu Schottky contacts to n-Ge were comparatively investigated. Lower values of barrier height, ideality factor and series resistance were obtained for the Au contact as compared to the Cu contact. The values of capacitance showed strong dependence on the bias voltage and the frequency. The presence of an inversion layer at the interface might reduce the intercept voltage at the voltage axis, lowering the barrier height for C-V measurements, especially at lower frequencies. In addition, a higher interface state density was observed for the Au contact. The generation of sputter deposition-induced defects might occur more severely for the Au contact; these defects affected both the I-V and C-V characteristics.

        Beauveria bassiana JEF-007 with strong virulence against Riptortus pedestiris was selected for the Agrobacerium tumefaciens-mediated transformation(AtMT). AtMT generated two transformants, B1-06 and C1-49, showed significantly reduced virulence against R. pedestris. To identify the virulence-related genes, thermal asymmetric interlaced(TAIL) PCR and flanking region analysis were performed. From the analysis, two genes, Complex I intermediated-associated protein 30(CIA30) and Autophagy protein 22(Atg22), possibly related virulence in B. bassiana JEF-007. For the analysis of two putative virulence-related genes in JEF-007, hairpin RNA interference (hpRNAi) is under consideration. This work can provide the functional roles of the virulence-related genes in B. bassiana JEF-007.

        Monochamus saltuarius is one of the insect vector of pine wilt disease with Monochamus alternatus. The present study aimed to investigate the dose to induce sterile and the effect of sterility according to the gender of M. saltuarius. As the electron beam irradiation dose increased, the hatchability, adult eclosion rate and longevity of the former mid and late maturation feeding stage of adults was slightly reduced. However, there was no difference between these two adults. In addition, female adults were more sensitive to the electron beam than the male adults. Hatchability of the F1 generation of ♂T × ♀N o r♀T × ♂N (T: 200 Gy electron beam irradiation, N: 0 Gy) was completely suppressed. As electron beam irradiation dose increased, the fecundity of female adults were slightly decreased. Results by comet assay showed that electron beam irradiation induced as dose increased DNA damage in M. saltuarius adults. These results suggest that SIT using electron beam may be useful for control of M. saltuarius.

        Composite resins are developed as restorative materials to improve esthetics and mechanical properties. To improve the physical properties of resin material, resin filler have to be added. However, no imaging method is adopted for resin filler distribution. Optical coherence tomography (OCT) is a optical imaging technique to delineate microscopic structures within biological tissue. The OCT application to dental composites resin and its filler is not described yet. So, this new and advanced optical method is needed for clinical application for evaluation of dental composite resin. To analyze the spatial distribution of dental composite resin and to evaluate the resin restoration in cavity, frequency domain optical coherence tomography (FD-OCT) was used for their analysis. Resin restored tooth was prepared. For morphological observation, serially sectioned teeth, conventional X-ray taking and micro computed-tomography (CT) images were compared with OCT images. The experiment has done to evaluate the success of the resin restoration using 3 dimensional structure OCT image. In this research, OCT is evaluated as a new technique to image resin restoration. The evaluation of resin restored tooth was performed by OCT. Inappropriate restoration such as marginal adaptation, large porosities, internal integrity and poor contour could be detected. Resin filler also could be checked by OCT. The distribution, number, regularity and size of resin filler can be differentiated from several commercial products. Considering the characteristics of the OCT, it can be used to evaluate the defects of resin restoration, resin filler distribution, and internal integrity between resin material and tooth structure. The OCT can be considered to be a new and advanced method for the evaluation of resin restorations.

        Sustainability is about how biological systems remain diverse and productive indefinitely. Long-lived and healthy wetlands and forests are examples of sustainable biological systems. People do not only focus on economy but also focus on social and environment. The Dow Jones Sustainability Index (DJSI) was created in 1999 which was based on economy, social and environment to evaluate and rank companies according to their corporate sustainability performance. In this paper we try to find out how to build sustainability index based consumers’ perception instead of company’s internal data and find what influence customers’ satisfaction upon sustainable fashion products in traditional fashion markets. The data was collected in Dongdaemun Market which is the biggest Korean traditional fashion market.

        Supply and demand patterns have dynamically changed in recent years due to the increased global competition. Firms have selected quality and price as competition components and have accomplished corporate innovation in order to achieve competitive advantage. Innovation has been recognized as the way to enhance corporate competitiveness and to continuously grow in churning global competition (Homburg, Schwemmle, & Kuehnl, 2015; Moon, Miller, & Kim, 2013). Although innovation becomes a common means to improve a firm’s performance, it has the limitation of achieving a firm’s strategic goal as a long-term strategy. Thus, firms need to have more fine-grained strategies to survive in dynamically changing business environment, such as design innovation (Moon et al., 2015). For example, Apple has produced its products (e.g., iPhone, iPod and iPad) focusing on innovative product design to influence consumer purchase intention. Design can lead to a distinct competitive advantage (Bolch, 1995). Furthermore, product design can be used by firms to create amd enhance brand recognition, as well as to increase firms’ value (Mozota, 2002). Brand experience positively influences customer satisfaction and brand loyalty (Brakus, Schmitt, & Zarantonello, 2009). Thus, we assume that design experience and product innovation have a positive effect on consumers’ purchase behavior and customer value. However, while the importance of design innovation is recognized, it is not easy to apply the design innovation to marketing due to the lack of relevant research in the field. In fact, relevant research on the influence of innovative new product design and design experience on customer value is scarce. Therefore, the purpose of this study is to investigate how brand experiences and innovative product design affect customer value. Successful innovation is accomplished by identifying customer needs first and developing innovative products to satisfy their needs (Hauser et al., 2006). Design is seen as the core of innovation and the moment when a new object is conceived of, devised, and shaped in a prototype form (Landwehr, Wentzel, & Herrmann, 2013). Verganti (2008) studies the concept of "user-centered design," which describes how companies can use design to improve their relationships with users and develop a better understanding of user needs. In this research, design innovation has three dimensions: aesthetic attributes, feature attributes, and emotional attributes. First, aesthetic attributes focus on the product design itself. The aesthetic appearance of a product has a large bearing on its potential market share (Liu, 2003). Second, feature attributes focus on the product features and functional aspects that are required to satisfy customer needs. Feature attributes enable performance that can give results in the operating process (Crawford & Di Benedetto, 2007). Third, emotional attributes focus on consumers’ feeling when they purchase a new product to satisfy their needs. Emotional attributes are generated by consumers’ experience when they purchase a new product in the store. The more the product design satisfies customer's emotional needs, the more customers’ attention is attracted to the purchase of a product (Mokarian, 2007). A product satisfying the aesthetic, feature, and emotional attributes through design innovation provides a new experience to customers (Desmet & Hekkert, 2007). A consumer’s purchase decision making is affected by both direct and indirect experience of using the product and the function of product (Brakus, Schmitt, & Zarantonello, 2009). Therefore, a designer comes to design the product, taking an interest in the experience that the product gives besides its shape and function. Product experiences occur when a customer interacts with the product ̶ for example, when customers search for, examine, and evaluate products (Hoch, 2002). The product experience can be direct, i.e. when there is physical contact with the product (Hoch & Ha 1986) or indirect, i.e. when a product is presented virtually or in an advertisement (Hoch & Ha 1986; Kempf and Smith 1998). Brand experience can be split into four dimensions (sensory, affective, intellectual, and behavioral), which are differentially evoked by various brands (Brakus, Schmitt, & Zarantonello, 2009). According to previous studies, these four experience dimensions (sensory, affective, intellectual, and behavioral experience dimensions) have an effect on customer satisfaction and customer loyalty. Customer value can be defined as the trade-off between the benefits and sacrifices as a customer purchases a product or service from a supplier (Ulaga & Chacour, 2001). Ulaga and Chacour presented three dimensions of customer value: product-related components, service-related components, and promotion-related components. The researchers argued that customer value could be an important strategic marketing tool to clarify a firm's proposition to customers. Product-related components are intrinsic product characteristics. Product quality is a key factor of relationship value (Ulaga, 2003). Customer value consists of product value and service value. Customer value can be enhanced by quality, diversity, payment, and service quality and decreased by price, convenience, and risk (Jarvenpaa & Todd, 2003). Service-related components include all aspects of service associated with the product. Various service components play an important role in differentiating a supplier's offering (Narus & Anderson, 1996). Promotion-related components include all items used to promote the product to the customer. For all purchasing processes, it is necessary to assess the perceived customer value, such as service quality and promotional quality (Qualls & Rosa, 1995). In the present study, we conducted a research survey with 300 subjects and analyzed the data. In order to test the reliability of questionnaire, Cronbach's alpha was used. In order to test the validity, an exploratory factor analysis was conducted. Measurement was made for 3 variables, i.e. design innovation, design experience, and customer value. Three variables (aesthetical attributes, feature attributes, and emotional attributes) were used for design innovation. Three types of attributes were introduced for a mobile phone design innovation. Four dimensions (sensory, affective, intellectual, behavioral) were measured using a technical design experience and a humanistic design experience. Three variables (product-related customer value, service-related customer value, and promotion-related customer value) were employed for customer value. The results of the analyses demonstrate that design innovation has a positive effect on design experience, while design experience has a positive effect on customer value. Aesthetic attributes of design innovation have a positive effect on technical design experience and humanistic design experience. Feature attributes have a positive effect on the technical design experience and the humanistic design experience. Emotional attributes have an effect on the technical design experience and the humanistic design experience. The technical design experience has a positive effect on product-related customer value, service-related customer value, and promotion-related customer value. The humanistic design experience has a positive effect on product-related customer value, service-related customer value and promotion-related customer value. This study will make it possible to empirically examine how customer's experience in design innovation affects customer value. Our results will provide a theoretical foundation for examining a relationship between variables regarding how design innovation influences customer value through design experience. It is intended to give a direction as to the design innovation of firms by clarifying and presenting antecedent factors having an effect that design innovation produces on customer value. The results of the present study will inspire designers to design in consideration of design experience. Finally, our study will provide marketers with guidelines as to how design experience can influence customer satisfaction and loyalty.

        The Korean energy demand-supply policy has changed from supply-concentrated management to demand-concentrated management with low consumption and high efficiency. Given these policy changes, this study focuses on investigating the marketing strategies of public policies that are necessary to execute policy effectively and to achieve the intended effect. More specifically, this study reviews details pertaining to the four elements of energy demand management policy: the development and commercialization of core technologies for energy efficiency, energy saving business growth, innovations in energy demand management, and reasonable energy price policies. We furthermore analyze the effects of introducing an energy-efficiency certification system to both companies and consumers via an energy policy implementation. We find solutions to achieve the goals of the energy demand management policy via effective marketing of the energy-efficiency certification system. This investigation contributes to developing marketing strategies to achieve certain public policy effects. We additionally focus on how the characteristics of an energy-efficiency certification system—such as public benefits, brand trust and customer value—affect customer perception and the effect of policy implementation. According to our findings, trust in the energy-efficiency certification system and the four elements of energy policy influence firms and consumers’ realization and are effective at accomplishing the goals of the energy-efficiency policy. Energyefficiency certification help firms to invest in energy-efficient facilities; such certification also motivates reasonable energy consumption levels and the option to select highly energy-efficient products. By employing a certification system actively as a means of governmental policy and providing accurate energy-efficiency information to firms and consumers, it is possible for firms to produce highly energyefficient products and for consumers to choose efficient products. In this way, governments, firms, and consumers are able to accomplish the goals of the policy.

        Mealybugs (Hemiptera: Pseudococcidae) are major pests of a wide range of crops and ornamental plants worldwide, and represented by 56 species in Korea. Occurrence of, or damage by, the longtailed mealybug, Pseudococcus longispinus Targioni-Tozzetti has not been reported since 2002. However, for the first time in many years, P. longispinus was reported at Phalaenopsis orchids by Kim et al in 2015. Therefore, the present study aimed to investigate the distribution of P. longispinus which is usually found inside a greenhouse or a building where the host plants are. We have collected 129 mealybug samples at 254 sites from Korea. Among these, 27 of P. longispinus and 62 of an unidentified Pseudococcus species were found mainly in ornamental plants such as Heteropanax fragrans, commonly known as happy trees in Korea. Morphological characteristics of the unidentified mealybug were very similar to those of P. longispinus. However, the genetic variability in COI sequence comparison was significantly different between the two species. Further studies are needed to clarify the valid name for this unidentified species, and we are currently working on it.

        Although expression of foreign genes in a crop species has been target techniques for powerful protection against insect pests, classical breeding programs using varietal resistance of a crop are still being processed. It is, however, frequently difficult to find key products expressed from resistance-related genes in the variety, and those action mechanism. Here, an unterminated story about seed of a mungbean (Vigna radiata) variety with high resistance against the adzuki bean weevil and the bean bug is introduced. The two insects cannot survive on seeds of the variety, although they well develop on susceptible ones. Molecular markers linked to the resistance were selected through BAC library screening and near isogenic lines, and finally a bruchid resistance gene was suggested after map-based cloning approaches. Starvation and chemicals were suggested for a resistant mechanism and a related factor through feeding and behavior experiments, respectively. The seed flour was extracted with organic solvents, and isolated into several fractions on chromatography. Several peaks on HPLC in a fraction were related with the high mortality of the bean bug. A partial structure in an isolated chemical was observed before full identification.

        Hypocreales entomopathogenic Beauveria bassiana and Metarhizium anisopliae are well-known biological control agents worldwide and have high potential in industrialization. However their thermo-susceptibility limits long-term storage under high temperature conditions and high insecticidal activity after application to target pests. Herein we isolated highly virulent isolates, B. bassiana JEF006 and JEF007 and M. anisopliae JEF003 and 004, and produced in three grains, as substrates for solid cultures, followed by thermotolerance assays to compare the potential of the three substrates. The JEF isolates were exposed to dry and wet heat at 50°C and overall conidia were more stable under dry heat condition rather than wet heat. Of the three grains, Italian millet was superior to the other grains in the production of thermotolerant conidia. Additionally Italian millet did not severely aggregated, which enabled air to penetrate into the substrate well compared to the sorghum and millet. JEF isolates were more thermotolerant when they were kept in oil conditions. The conidia of JEF 007 and 003 wild type and AtMT-based generating random mutants were subjected to SDS-PAGE. A significant relationship between conidial thermotoelrance and detected proteins was observed. This work suggests that Italian millet can be used as an effective substrate to produce more thermotolerant conidia, thus maintaining viability for long times under unfavorable environment and biological activity against target pests.
