The study on the tire noise due to the On-Board Sound Intensity test method. The object of this project is to prepare the countermeasure of the noise reduction according to collect tire/road noise data under various influencing factors by using On-Board Sound Intensity test method. To accomplish the object ; A automotive is used as a test platform to test tire/road noise by changing different types of tires and using On-Board Sound Intensity test system. The influence of inflation pressure, road, load, speed and pattern type on tire/road noise is compared and analyzed. At the same time, the mechanism of tire/road noise is analyzed, which provides a experimental basis for tire noise reduction.

Intensive Monitoring Survey of Nearby Galaxies (IMSNG) is a high cadence observation program monitoring nearby galaxies with high probabilities of hosting supernovae (SNe). IMSNG aims to constrain the SN explosion mechanism by inferring sizes of SN progenitor systems through the detection of the shock-heated emission that lasts less than a few days after the SN explosion. To catch the signal, IMSNG utilizes a network of 0.5-m to 1-m class telescopes around the world and monitors the images of 60 nearby galaxies at distances D < 50 Mpc to a cadence as short as a few hours. The target galaxies are bright in near-ultraviolet (NUV) with MNUV < - 18.4 AB mag and have high probabilities of hosting SNe (0.06 SN yr-1 per galaxy). With this strategy, we expect to detect the early light curves of 3.4 SNe per year to a depth of R  19:5 mag, enabling us to detect the shock-heated emission from a progenitor star with a radius as small as 0.1 R. The accumulated data will be also useful for studying faint features around the target galaxies and other science projects. So far, 18 SNe have occurred in our target fields (16 in IMSNG galaxies) over 5 years, confirming our SN rate estimate of 0.06 SN yr-1 per galaxy.

We present the analysis of KMT-2016-BLG-0212, a low flux-variation (Iflux−var ∼ 20 mag) microlensing event, which is in a high-cadence (Γ = 4hr −1) field of the three-telescope Korea Microlensing Telescope Network (KMTNet) survey. The event shows a short anomaly that is incompletely covered due to the brief visibility intervals that characterize the early microlensing season when the anomaly occurred. We show that the data are consistent with two classes of solutions, characterized respectively by low-mass brown-dwarf (q = 0.037) and sub-Neptune (q < 10−4) companions. Future high-resolution imaging should easily distinguish between these solutions.

In late 1950’s, the beginning of container revolution has started a new paradigm shift in maritime industry worldwide. This new paradigm has become a major reason for seaport systems to prepare their physical capacity, space availability, multi-modalism, transport connectivity via regionalisation. However, in early 2010’s the introduction of industrial revolution 4.0 (IR4.0) which starts the era of immersive digitalization proved that seaport systems need to be prepared to face pattern of unstable magnitudes in dynamic maritime trade. Therefore, this paper analyses key components required for Malaysian seaport system to be aligned with the key requirements in IR4.0. By employing document analysis, this research analyses the challenges faced by Malaysian seaport system as well as suggests strategies to muddle through the key requirements of IR4.0. The findings from this research indicate that Malaysian seaport system need to be improved by enforcing skill-based education system, flexibility in labour structure, development in skill and competence level as well as improvement in infrastructure suitability. The findings from this research also reflect significant strategies to improve seaport system in the era of IR4.0 including enhancing requirements for intermodal terminals, improving preparation for seaport alliances, developing mechanism for interoperability, improving utilisation of intra and interregional economic development as well as scrutinising safety and security.

Anecdotal evidence suggests that incidents like the recall of the exploding Samsung Galaxy 7 phones drive owners of other (competing) brands to experience and express feelings of joy when a rival brand fails (e.g., “the hottest phone in the streets!”). Although consumers sometimes experience brand-related schadenfreude—that is, joy out of other brand’s failure—, psychological processes driving schadenfreude are not clearly understood (Hickman & Ward, 2007; Van Dijk, Van Koningsbruggen, Ouwerkerk, & Wesseling, 2011). We propose that schadenfreude may be elicited by consumers’ tendencies to stand by their choices (Ye & Gawronski, 2016). We demonstrate that consumers show higher levels of schadenfreude if their choice is disconfirmed; for example, by a comparative product review that evaluates their chosen brand to be inferior to a rival non-chosen brand. Furthermore, this effect is moderated by the popularity of the chosen brand and mediated by feelings of self-threat. Moreover, we show that this effect is stronger for narcissists. We also find evidence that schadenfreude is a means for consumers to reaffirm their sense of self after they experience a self-threat induced by the disconfirmation of their choice.

The study examines physiological and neuronal processes of 26 inexpert wine drinkers in order to understand how consumers judge and choose wines during product experience. We analyzed if an increase in the beta band activity can be related to reward process and individual preference for a wine. We predicted that tasting different wines influence participants' preferences and beta band activity. We also hypothesized that high beta band activity would be related to preferences for a wine. The results confirmed that 1) tasting different wines modulate individual preferences and beta band activity and 2) the higher preferences for a wine corresponded to a stronger decrease in beta band oscillations.

This paper develops a conceptual model of international social media marketing strategy that describes how culture shapes consumers’ use of social media around the world. Drawing from cultural psychology, marketing, and computer information systems, we use Kietzmann et al.’s (2011) functional building blocks of social media to organize social media functions, then explicate how various dimensions of culture affect the way such social media functions are used across cultures. By delineating these complex relationships, our model and the propositions that stem from it offer directions for future research and advance understanding of cross-cultural differences with implications for businesses that provide social media or capitalize on social media for global reach in the international marketplace.

The Korea Astronomy and Space Science Institute plans to develop a coronagraph in collaboration with National Aeronautics and Space Administration (NASA) and to install it on the International Space Station (ISS). The coronagraph is an externally occulted one-stage coronagraph with a field of view from 3 to 15 solar radii. The observation wavelength is approximately 400~nm, where strong Fraunhofer absorption lines from the photosphere experience thermal broadening and Doppler shift through scattering by coronal electrons. Photometric filter observations around this band enable the estimation of 2D electron temperature and electron velocity distribution in the corona. Together with a high time cadence ($<$12~min) of corona images used to determine the geometric and kinematic parameters of coronal mass ejections, the coronagraph will yield the spatial distribution of electron density by measuring the polarized brightness. For the purpose of technical demonstration, we intend to observe the total solar eclipse in August 2017 with the filter system and to perform a stratospheric balloon experiment in 2019 with the engineering model of the coronagraph. The coronagraph is planned to be installed on the ISS in 2021 for addressing a number of questions (e.g., coronal heating and solar wind acceleration) that are both fundamental and practically important in the physics of the solar corona and of the heliosphere.
