        The addition of a large amount of alloying elements reduces the compactibility and increases the compacting pressure, thereby shortening the life of the compacting die and increasing the process cost of commercial PM steel. In this study, the characteristic changes of Fe-Mo-P, Fe-Mn-P, and Fe-Mo-Mn-P alloys are investigated according to the Si contents to replace the expensive elements, such as Ni. All compacts with different Si contents are fabricated with the same green densities of 7.0 and 7.2 g/cm3. The transverse rupture strength (TRS) and sintered density are measured using the specimens obtained through the sintering process. The sintered density tends to decrease, whereas the TRS increases as the Si content increases. The TRS of the sintered specimen compacted with 7.2 g/cm3 is twice as high as that compacted with 7.0 g/cm3.

        Honey production from approximately 1.7 million colonies owned by around 21 thousand beekeepers was almost 36 thousand M/T in Korea. Pollen has used as a food and medicine from before the Joseon Dynasty period in Korea. Pollen grains such as acorn (Quercus acutissima), actinidia (Actinidia arguta) and green tea (Camellia sinensis) are popular in the markets in Korea. But stiff pollen wall hindered dissolution of polysaccharides and lowered extraction efficiency. In the present study, we measured the antioxidant activity and the total polyphenol content from the pulverized and lyophilized green tea pollen grains inoculated with 6 kinds of fungi to confirm the husk removal effect. The total polyphenol content of green tea pollens was highest in lyophilized pollen medium inoculated with Armillaria mellea, and was lowest in pollen inoculated with Lentinula edodes. Total polyphenol content of the lyophilized pollen was higher than that of the refined pollen and the pulverized pollen in green tea pollen germinated with A. mellea. The total polyphenol content of the lyophilized green tea pollens germinated with A. mellea was 1.4-fold higher than that extracted with water. Measurement of antioxidant activity using the DPPH free radical scavenging method showed that the lyophilized green tea pollen grains germinated with A. mellea had the highest and that germinated with L. edodes was lowest in antioxidant activities. The lyophilized green tea pollen grains germinated with A. mellea was 2 to 4 times higher than that extracted with water in the antioxidant activity of DPPH free radical scavenging. Many germinated cells were formed around pore of green tea pollen inoculated with L. edodes, while those were formed at the end of hyphae derived from green tea pollen grains inoculated with A. mellea.

        The continuous exploration in deep seawater from Korea makes us lead the discovery of ancient Chlorophyta, Palmophyllum, in the Korean coast. The phylogenetic analyses of 18S rRNA and rbcL genes demonstrate that our specimens are Palmophyllum crassum (Naccari) Rabenhorst, recorded in Japan and clearly distinguished from P. umbracola from New Zealand and California, USA. Palmophyllum crassum grows in the subtidal region, 8-30 m deep, and has a crustose thallus which is closely adherent to substrates such as non-geniculate crustose coralline algae, sponge, shells, or rocks. P. crassum is composed of numerous spherical cells embedded in the gelatinous matrix. The discovery of this ancient green seaweed implies that the Korean coast is one of the hotspots of algal species diversity and has the suitable marine environment for algal speciation. We suggest the grounds to conserve the Korean coast environmentally as the biodiversity center of marine species by studying the phylogeny of seaweeds.

        Performance evaluation has been done using financial indices which are generally regarded as inappropriate for the organizations which are innovative and progressive. Thus, the Balanced Scorecard(BSC) was developed considering long term performance and invisible performance. This BSC has four perspectives of finance, customer, internal operation, and learning. Based on the BSC, a new BSC has been derived with a fifth view of environmental and social perspective, which is now called as a Sustainability BSC. In this study, we evaluated Green IT initiatives using the Sustainability BSC. The initiatives are categorized as RFID, telepresence, paperless office, logistics management etc. The initiatives were evaluated from the view of five perspectives, resulting in high cor relationships among finance, internal operation, and environmental and social perspectives. Namely, good initiatives from the view of environmental/social perspective are also evaluated as good from the view of finance and internal operation perspectives. In this study, we recommend organizations to introduce Green IT initiatives by showing how Green IT initiatives have contributed to the organizations.

        The catch performance of the silver-white jig for automatic jigging machine, developed to improve the effectiveness of LED fishing lamp in catching squid, was compared to that of the conventional green jig. The vessels used in this investigation were Haesong-ho (A-vessel), a training vessel of Gangwon State University and Haengbok-ho (B-vessel), a commercial fishing boat. In the case of the A-vessel, five to eight automatic jigging machines were used in the fishing operation with a 31.3 kW LED fishing lamp in summer. As for the B-vessel, fourteen automatic jigging machines were used with a 43.2 kW LED fishing lamp in autumn and winter. The results showed that the catch performance of the silver-white jig was similar to that of the green jig in the case of the A-vessel (p>0.05). However, in the case of the B-vessel, the catch performance of the silver-white jig was superior to that of the green jig in both winter (p<0.05) and autumn (P<0.001). Based on the catch performance results regarding the B-vessel in autumn, it is expected that the annual income increase that can be earned by using the silver-white jig will be KRW 26,385,000.

        In recent years, companies, consumers, and society have increasingly committed to actions aimed at protecting the environment. Thus, environmental activity has become central to companies’ strategies. Apparel is becoming a disposable product, resulting in a sharp consumption increase (Hwang et al., 2016). The fast growing rates of apparel products consumption and waste lead to an environmental crisis. Smaller brands as well as many multinational companies, including large chains started selling clothes made of ecological fiber. According to the Ethical Fashion Forum, green fashion refers “represents an approach to the design, sourcing and manufacture of apparel which maximizes benefits to people and communities while minimizing impact on the environment.” (Cervellon & Wernerfelt, 2012). The purpose of this research is to analyze the relationship between perceived effectiveness of green products, attitude toward advertising, brand attitude, purchase intention and green behavior intention and to identify how claim specificity types, cognitive style and sustainable involvement influence on the relationship between variables.

        In consideration of the existing eco-friendly marketing research, it is only focusing on the type and characteristics of eco- friendly consumers. Therefore, in order to carry out more systematic and comprehensive eco-friendly marketing research, it is necessary to complement the comprehensive model that examines the mechanism by which the leading variables of the enterprises factors affecting consumer’s eco-friendly consumption behaviors. In this research, based on previous studies and literature considerations, it tries to present a research model that the core benefits and relational benefits of the retail store which is the advantage of VMD affect eco-friendly consumption behavior through consumer's implicit and explicit motivation. And, considering the environment, this study assumes the regulatory role of the perceived risk on the environmental problems under the relationship between green consumption motive and consumption behavior. The purpose of this research is as follows. First, it clarifies the influence of the benefits of eco-friendly VMD in fashion retail stores on the eco-friendly consumption motive, which is a psychological factor of consumers, as a leading variable of corporate factors affecting consumers’ green consumption behavior. The core benefits and relational benefits provided by eco-friendly VMD will identify differentiated impacts on consumer motivation, which is a psychological factor that drives green consumption behavior. Second, the types of motivations that cause eco-friendly behavior are classified into explicit motivation and implicit motivation, and this study tries to find out which type of motivation better predicts eco-friendly consumption behavior. Third, it tries to verify the moderating role of environmental perceived risk in the relationship between explicit motivation, implicit motivation and green consumption behavior. By further organizing the theme of eco-friendly marketing research, this study has its academic significance in that it derives a comprehensive model, moderating consumers’ green consumption behavior regarding eco-friendly marketing stimulates. It reveals the mechanisms that affect green consumption behavior backed by fashion retail stores where consumer buying behavior actually takes place. Based on this research, it is expected that subsequent studies of a more fragmented viewpoint for fashion retail stores’ eco-friendly marketing will be developed that will give consideration to consumers' green consumption behavior. Practically, the results of this research can be utilized very conveniently. In a practical dimension, if it becomes possible to thoroughly understand the mechanism by which eco-friendly VMD stimulation leads to green consumption behavior, retailers are possible to formulate an environmental marketing strategy peculiar to the target market segment. From a socio-policy perspective, retailers can encourage consumers' eco-friendly consumption by giving a stimulus of VMD to them. Moreover this study will promote companies to develop and manage healthier and more sustainable products.

        Companies frequently use luxury or green as a brand extension strategy. The present research suggests that the success of the luxury or green brand extension depends on the parent brand’s core attribute-whether the parent brand is primarily luxury or green. In two experiments involving real brands (BMW, Prius, Chanel, Patagonia) across multiple product categories (automobile and bag), we investigated consumers’ evaluation of luxury green extension products (i.e., multi-attribute products with luxury and green attributes) whose parent brand is luxury (e.g., BMW) or green (e.g., Prius). Study 1 showed that luxury green products with luxury roots (i.e., parent brand is luxury) are evaluated more favorably than those with green roots (i.e., parent brand is green). Study 2 investigated the mechanism of perceived fit. Whereas luxury green product with luxury roots was perceived to have a high level of fit, the luxury green product with green roots was perceived to have a lower level of fit. Our findings encourage the luxury parent brand to extend green whereas discourage the green parent brand to extend luxury.

        Spherical-type zirconia granules are successfully fabricated by a spray-drying process using a water solvent slurry, and the change in the green density of the granule powder compacts is examined according to the organic polymers used. Two organic binders, polyvinyl alcohol (PVA) and 2-hydroxyethyl methacrylate (HEMA), which are dissolved in a water solvent and have different degrees of polymerization, are applied to the slurry with a plasticizer (polyethylene glycol). The granules employing a binder with a higher degree of polymerization (PVA) are not broken under a uniaxial press; consequently, they exhibit a poor green density of 2.4 g/cm3. In contrast, the granule powder compacts employing a binder with a lower degree of polymerization (HEMA) show a higher density of 2.6 g/cm3 with an increase in plasticizer content. The packing behavior of the granule powders for each organic polymer system is studied by examining the microstructure of the fracture surface at different applied pressures.
