        This paper investigates a theoretical and experimental evidence for a niche strategy for small and medium online shopping malls to survive against large famous shopping malls dominating the E-commerce market. The present study explored both theoretically and empirically how consumers’ preferences for alternatives in online shopping context are affected by their construal level and concentrated its efforts on the verification of the phenomenon under various frames and regarding various categories(Liberman and Trope 1998; Liberman, Trope, and Stephan 2007, Liberman Trope, and Wakslak 2007). For this, this study demonstrates how chronic construal levels of consumers may affect their alternative choice for online shopping via various contexts (Experiment 1-3) and categories (Experiment 3-5). This series of experiments suggests that consumers with high construal level can be defined as a group that is relatively less susceptible to reputation of the shopping malls. Thus, strategically targeting this group of consumers will help small online malls lacking store reputation to mitigate their competitive disadvantage. Based on both existing literature and the experimental results as above, this research discusses possible methods for small online shopping malls to target high-construal segmentation.

        Generally, remarkable amount of Reclaimed Asphalt Pavement (RAP) is produced annually by pavement surface cutting: due to early distress on asphalt pavement layer and remodelling construction work on existing aged-asphalt pavement layer. In South Korea, various types of research on proper and optimized RAP material development and field application (including evaluation process) are performed because of increase of existing road maintenance budget and technology. The major material of RAP is recycled aggregate coated with aged asphalt binder. The advantages of application of RAP on asphalt pavement are recyclable material proportion can be increased due to re-using of existing aggregate and eco-friendly characteristics. However, more amount of specific additives (and/or agent) needs to be implemented during production with increase amount (and/or proportion) of RAP on virgin asphalt material inevitably. This action is highly needed because of recovery of penetration grade and absolute viscosity of final production. The required amount of additives tends to be vary based on different aging level of RAP, amount of RAP and types of virgin asphalt binder. But it is well known that required amount of additives tends to be increased with increase of RAP proportion compared to virgin asphalt mixture. Moreover, it also should be known that mere increase of additives on RAP asphalt can provide negative effect on its quality and mechanical performance. In this study, high penetration grade asphalt binder: contains between 200 and 300 level of penetration grade, was used for producing RAP asphalt mixture with small amount of required additive application. After the sample preparation, various characteristics of RAP asphalt were analysed with extensive experimental work.

        The purpose of this study is to present theoretical and experimental evidence for a niche strategy for small and medium online shopping malls to run business against large famous shopping malls prevailing the E-commerce market. For this, the present study demonstrates how chronic construal levels of consumers may affect their alternative choice for online shopping via various contexts (Experiment 1-3) and categories (Experiment 3-5). This series of experiments suggests that consumers with high construal level can be defined as a group that is relatively less susceptible to reputation of the shopping malls. Thus, strategically targeting this group of consumers will help small and medium-sized online malls lacking store reputation to mitigate their competitive disadvantage. Based on both existing literature and the experimental results as above, this research discusses possible methods for small and medium-sized online shopping malls to target high-construal segmentation.

        This study investigated the densification behavior of rhenium alloys including W-25 wt.%Re and Re-2W-1Ta (pure Re) during sintering. The dilatometry experiments were carried out to obtain the in-situ shrinkage in H2 atmo-sphere. The measured data was analyzed through shrinkage, strain rate and relative density, and then symmetricallytreated to construct the linearized form of master sintering curve (MSC) and MSC as a well-known and straightforwardapproach to describe the densification behavior during sintering. The densification behaviors for each material were ana-lyzed in many respects including apparent activation energy, densification parameter, and densification ratio. MSC witha minimal set of preliminary experiments can make the densification behavior to be characterized and predicted as wellas provide guideline to sinter cycle design. Considering the results of linearized form and MSC, it was confirmed thatthe W-25 wt.%Re compared to Pure Re is more easily densified at the relatively low temperature.

        Cicinela chinensis (Coleoptera : Cicindelidae) is usually distributed from Asian countries; Korea, Vietnam, China and Japan. In larval stage, they make hole on ground and eat small insects that pass over the hole, adult also predator on other small insects and they can move fast. They have regional morphological variation, usually variations were showed in elytral pattern and body colors. There are four subspecies, Cicindela chinensis chinensis, Cicindela chinensis flammifera, Cicindela chinensis japonica and Cicindela chinensis okinawana in Cicindela chinensis all of the world. Because of a lot of variation in elytra pattern and body color, identification of Cicindela chinensis is difficult. Therefore to know the distinct differences, comparison analysis by DNA sequence in COI gene was examined. In this paper COI comparison analysis of Cicindela chienesis from different location was examined. Also COI comparison analysis of species with different elytra pattern and body color collected in same location was done. Although they have different color pattern is same region, the result of COI sequence was same. Otherwise, although they have same color pattern in other regions, the result of COI sequence was different.

        Myanmar is located in the Southeastern region of Asia. It lies between latitudes 9° and 29°N, and longitudes 92° and 102°E. The bordering countries are China on the northern side, Thailand and Laos on the eastern region, Bangladesh on the western side and India on the northwestern region. Myanmar has a total area of 678,500 square kilometers (262,000 sq mi). The rainy season exists primarily during the months between June and September. Whiledry season stays during the months between December and April. Northern regions of the country are the coolest, with average temperatures of 21 ℃ (70 ℉). Coastal and delta regions have an average temperature of 32 ℃ (86.9 ℉). This expedition was conducted four times for three years. Among them we explored three area including Popa Mountain, Alaungdaw Kathapa National Park and Nat Ma Taung National Park[Popa Mountain(8.7~8.17, 2011; 7.24~8.3 2012; 2.18~2.28 2013), Alaungdaw Kathapa National Park(2.2~2.9, 2012) and Nat Ma Taung National Park(2.18~2.28 2013)]. Collecting methods was sweeping net, lignt trap, burket trap, pitfall trap with other method, and collected especially mainly Coleoptera and Lepidoptera. As the result, totally about 30 families in Coleoptera and 7 families in Lepidoptera were collected, among them Carabidae and Nymphalidae was revealed most diversity species.

        Myanmar, which has a total area of 678,500 square kilometers (262,000 sq mi), is the largest country in mainland Southeast Asia, and the 40th-largest in the world. It lies between latitudes 9° and 29°N, and longitudes 92° and 102°E. Much of the country lies between the Tropic Of Cancer and the Equator. It lies in the monsoon region of Asia, with its coastal regions receiving over 5,000 mm (196.9 in) of rain annually. Northern regions of the country are the coolest, with average temperatures of 21 ℃ (70 ℉). Coastal and delta regions have an average temperature of 32 ℃ (86.9 ℉). This expedition was conducted two times in two years. First, collecting expeditions of insect were conducted in Popa resort, Myanmar from Aug. 7, 2011 to Aug. 17, 2011. Second, collecting expeditions of Insect were conducted in Alaungdaw Kathapa National Park (AK National Park), Myanmar from Feb. 2, 2012 to Feb. 9, 2012. As a Protected area of the Forest department, these areas were almost natural conservation field and limited to collection actions. Usually on day time, butterflies collected by sweeping net, like various plants, they shows high diversity. Some Papilionidae species are difficult to meet because they fly very high and fast, usually they visit to top of trees. Up to now, 60 species of 7 families were confirmed. Materials are expected more than 100 species belonging to 10 families but it was difficult to identification because of lack of references of this areas. Among them, with rare species, manifold butterflies are provided with photos, ecological notes and activities of Myanmar.

        For advanced drinking water treatment of high turbidity water, we used the hybrid process that was composed of photocatalyst packing in space of between outside of multi-channel ceramic microfiltration membrane and membrane module inside. Photocatalyst was polypropylene (PP) beads coated TiO2 powder by CVD (chemical vapor deposition) process. Instead of natural organic matters (NOM) and fine inorganic particles in natural water source, standard NOM solution was prepared with humic acid and kaolin. Water-back-flushing of 10 sec was performed per every period of 10 min to minimize membrane fouling. Resistance of membrane fouling (Rf) increased and J decreased as concentration of humic acid changed from 2 mg/L to 10 mg/L, and finally the highest total permeate volume (VT) could be obtained at 2 mg/L. Then, treatment efficiency of turbidity and UV254 absorbance were above 96.4% and 78.9%, respectively. As results of treatment portions by membrane filtration, photocatalyst adsorption, and photo-oxidation in (MF), (MF + TiO2), (MF + TiO2 + UV) processes, turbidity was treated little by photocatalyst adsorption, and photo-oxidation. However, treatment portions of UV254 absorbance by adsorption (MF + TiO2) and photo-oxidation (MF + TiO2 + UV) at humic acid of 4 mg/L and 6 mg/L were above 9.0, 9.5 and 8.1, 10.9%, respectively.
