This study extends the previously classified typology of unplanned purchases to accommodate the increase in online purchases. We also measured the impact of unplanned purchases on shoppers from an emotional perspective. As a result, new types of unplanned purchases, such as "novelty," "recall," "salience," "reference price," "risk aversion," and "embodied cognition," were derived. Furthermore, among unplanned purchases, salience purchases were found to significantly increase shoppers' interest. This result indicate that the importance of marketing strategies that take salience into account for manufacturers and retailers.

H2O maser emission at 22 GHz in the circumstellar envelope is one of the good tracers of detailed physics and kinematics in the mass loss process of asymptotic giant branch stars. Long-term monitoring of an H2O maser spectrum with high time resolution enables us to clarify acceleration processes of the expanding shell in the stellar atmosphere. We monitored the H2O maser emission of the semi-regular variable R Crt with the Kagoshima 6-m telescope, and obtained a large data set of over 180 maser spectra over a period of 1.3 years with an observational span of a few days. Using an automatic peak detection method based on least-squares fitting, we exhaustively detected peaks as significant velocity components with the radial velocity on a 0.1 km s−1 scale. This analysis result shows that the radial velocity of redshifted and blue-shifted components exhibits a change between acceleration and deceleration on the time scale of a few hundred days. These velocity variations are likely to correlate with intensity variations, in particular during flaring state of H2O masers. It seems reasonable to consider that the velocity variation of the maser source is caused by shock propagation in the envelope due to stellar pulsation. However, it is difficult to explain the relationship between the velocity variation and the intensity variation only from shock propagation effects. We found that a time delay of the integrated maser intensity with respect to the optical light curve is about 150 days.

The uninhabited Senkaku islands, which have been administered by the Okinawan local government, have been claimed by Japan, China and Taiwan. The vicinity of the disputed islands has long been identified as possessing potential oil and gas resources. The territorial disputes have been intensified after the Japanese government nationalized the islands in 2012. The situation has been regarded as the most serious for Sino-Japanese relations in the post-war period in terms of the risk of militarized conflict. The Chinese government used “core interests” to describe national sovereignty over the islands which it will make no compromise at any price, while the Japanese government hardened its stance by insisting that there is no territorial dispute to negotiate with China over the islands. The peaceful settlements on the disputed islands are complicated because it involves history, economy, security and nationalism. This paper argues that the best way to ease territorial disputes will be to create a common economic zone based on mutual understanding and economic interests through the wisdom of the islands of Okinawa and Taiwan based on a growth triangle (GT) approach. China has been claiming that the disputed islands are under Taiwan’s jurisdiction. Both Japanese and Chinese central governments should leave all powers to both Okinawa and Taiwan governments for peaceful, joint development of the disputed waters.

To elucidate the mechanism associated with the development of heavy precipitation system, a field experiment was carried out in Jejudo (or Jeju Island) and Marado, Korea from 22 June to 12 July 2006. The synoptic atmospheric conditions were analyzed using the National Centers for Environmental Prediction-National Center for Atmospheric Research's (NCEP/NCAR) reanalyzed data, weather maps, and sounding data. The kinematic characteristics of each precipitation system were investigated by dual Doppler radar analysis. During the field experiment, data of four precipitation events with more than 20 mm rainfall were collected. In F case (frontal precipitation), a typical Changma front was dominant and the observation field was fully saturated. However there was no convective instability near the surface. LF case (low pressure accompanied with Changma front) showed strong convective instability near the surface, while a strong convergence corresponded to the low pressure from China accompanied with Changma front. In FT case (Changma front indirectly influenced by typhoon), the presence of a convective instability indicated the transport of near surface, strong additional moisture from the typhoon 'EWINIAR'. The convergence wind field was ground to be located at a low level. The convective instability was not significant in T case (precipitation of the typhoon 'EWINIAR'), since the typhoon passed through Jejudo and the Changma front was disappeared toward the northeastern region of the Korean peninsula. The kinematic (convergence and divergence) characteristics of wind fields, convective instability, and additional moisture inflow played important roles in the formation and development of heavy precipitation.

Surface fog coating methods to porous pavements with a polymer, that contains MMA as a main ingredient, are being widely used in Japan and called 'Top-Coat Processes'. They have lots of effects such as to prevention of the pavement void choking, improvement of the water permeability of the pavements and so on. The purpose of this research is to show the characterization of the polymer to optimize the functions of the polymer fog-coat methods. This study focused on the difference of 'wetting' by water among polymers used for the fog coatings, and calculation the surface free energy from the water contact angle on each material. At the end, the water permeability test were conducted using porous asphalt mixtures that were coated with several kinds of polymers. The permeability was also measured on the specimens that were forcibly choked by muddy water and the resistance to choking was compared. It is concluded that the reduction of the surface free energy between water and a polymer improves the life of the permeability functions of porous pavements. Improvement of water permeation capacity and void-blocking controlling effects can be quantitatively evaluated using the interfacial tension (γsl) with water for the coating material (high-viscosity asphalt and hardening resin binder). Consequently, the smaller the γsl of the coating material the higher the water permeation capacity and void-blocking controlling effects of the porous asphalt pavements.

Recently the Marangoni convention is supposed to be an important phenomenon that significantly affects the solidification. For understanding the Marangoni convection mechanism, visualizing the convention phenomenon of molten tin with ultrasonic has been conducted. This paper reports developing a tracer material of micro metal balloon that is used in the molten system. We have succeeded in coating the surface of Shirasu-ballons with nickel by plating process. The obtained metal balloon is spherical and some characterizations were conducted.

SUS316L stainless steel, commercial pure Titanium and Ti-6Al-4V alloy powders applied by Mechanical Milling (MM) process are sintered by Hot Roll Sintering (HRS) process. Microstructure and mechanical properties of those HRS materials is investigated. The microstructures of materials produced by HRS process consist of fine grains and work-hardened structure, that is, the hybrid microstructure. Tensile test of the HRS material demonstrated the good mechanical properties. These results show that the HRS process is very effective to the improvement of mechanical properties in the SUS316L stainless steel, commercial pure Titanium and Ti-6Al-4V alloy.

In late years, from a trend for ecology of auto motive engine, low emission and low fuel consumption of engine become a social assignment. At the same time, the high output (high efficiency) is required, too. In order to meet those requirements, in comparison with conventional engines, lean A/F (Air fuel ratio) setting is becoming popular for the high performance engines of late years. Exhaust valve seat (sintered material) used in these engines has a problem in wear resistance, because it is exposed to the surroundings that is clean and a high temperature in comparison with the conventional engines. Therefore, wear mechanism with lean A/F of engine was analyzed.The exhaust valve seat (sintered material), that was superior in wear resistance, was developed.

In this study, nano grain W is fabricated by Severe Plastic Deformation-Powder Metallurgy (SPD-PM) process. W powder and W-Re powder mixtures are processed by SPD-PM process, a Mechanical Milling (MM) process. As results, a nano grain structure, whose grain size is approximately 20nm, is obtained in W powder after MM for 360ks. A nano grain W compact, whose grain size 630nm, has excellent deformability above 1273K. A nano grain W-10Re compact is composed of equiaxed grain, a grain growth is restrained and has low dislocation density after the large deformation; therefore it is considered that W-Re compact shows superplasticity.

The relationship between the powder particle size change and a mechanical property of the Metal Injection Molding (MIM) product was examined in detail. The XRD results indicate that the diffraction peaks of BCC appeared in compacts of powder particle size of 4 to as well as the bulk SUS630. However, the diffraction peaks from both BCC and FCC were observed in the compact with powder size less than . TEM observation revealed that the powder with those BCC/FCC two phase structure have a finely dispersed precipitates. Because the Si is ferrite stabilizing element, decrease of Si composition in the matrix phase by the precipitation resulted in formation of the retained austenite. Therefore, controlling the elements such as Si as well as oxygen decrease is very important to obtain a normal microstructure in ultra-fine powder (<3μm) injection molding.

질소가스에 대한 헬륨가스의 선택도가 매우 높은 poly(carbobenzoxy-L-lysin)(PCLL)로 제조된 균일막의 투과도를 증가시키기 위해서 디옥산과 DMF의 20% 용액을 이용하여 캐스팅법으로 비대칭 다공성막을 제조하였다. 이 막에 대해서 표면에서의 공극의 수와 공극크기의 분포를 측정하였으며, 표면층의 두께는 주사전자현미경과 투과전자현미경을 이용하여 측정하였다. 평균공극크기와 평균공극밀도는 DMF용액보다 디옥산용액으로 제조한 경우 더 낮은 값을 나타내었으며, 어느 비대칭 다공성막에 있어서 공극의 형성메카니즘으로 설명할 수 있다. 투과계수는 표면층을 통한 점성흐름으로 어느 정도 설명될 수 있으나, 선택도는 점성흐름의 이론과 대치되었다.
