An effective method in destination promotion
This study examined the visiting intentions of those who identify the value of a national park as a “Zest for Living” and those who identify it as a “Sense of familiarity with nature.” Even in the case of the same picture, visiting intentions varied with taste and values. Based on this finding, a suggestion was obtained for the effective promotion of destinations

Recovery of Destinations: An Examination Using the Tourism Area Life Cycle
In mature market, many destinations are sluggish growth. However, some destinations experience significant increases in visitors. This study examines the factors affecting the recovery and decline of destinations in Japan as an example of mature market. First, we analyze in term of the relation between destination and market (H0a), then, focus on destination itself (H0b/H0c). Using the framework of the tourism area life cycle (TALC), we found that destinations effectively respond to market trends and they can recover from stagnant growth. We also found that a change in the size and market share (in terms of individual or group visitors) of a destination is not relevant to the change in visitor’s number of the destination
Non-Orthogonal Multiple Access for mmWave Drones with Multi-Antenna Transmission
Unmanned aerial vehicles (UAVs) can be deployed as aerial base stations (BSs)
for rapid establishment of communication networks during temporary events and
after disasters. Since UAV-BSs are low power nodes, achieving high spectral and
energy efficiency are of paramount importance. In this paper, we introduce
non-orthogonal multiple access (NOMA) transmission for millimeter-wave (mmWave)
drones serving as flying BSs at a large stadium potentially with several
hundreds or thousands of mobile users. In particular, we make use of
multi-antenna techniques specifically taking into consideration the physical
constraints of the antenna array, to generate directional beams. Multiple users
are then served within the same beam employing NOMA transmission. If the UAV
beam can not cover entire region where users are distributed, we introduce beam
scanning to maximize outage sum rates. The simulation results reveal that, with
NOMA transmission the spectral efficiency of the UAV based communication can be
greatly enhanced compared to orthogonal multiple access (OMA) transmission.
Further, the analysis shows that there is an optimum transmit power value for
NOMA beyond which outage sum rates do not improve further
