In the future, ultra-high energy cosmic ray (UHECR) observatory will be expanded due to the small flux. Then, cost reduction is useful strategy to realize a huge scale observatory. For this purpose, we are developing a simple structure cosmic ray detector named as Cosmic Ray Air Fluorescence Fresnel-lens Telescope (CRAFFT). We deployed CRAFFT detectors at the Telescope Array site and performed a test observation. We have successfully observed UHECR air showers. We will report the status and the result of the test observation.

This paper provides a stocktake of the status of hill country farming in New Zealand and addresses the challenges which will determine its future state and performance. It arises out of the Hill Country Symposium, held in Rotorua, New Zealand, 12-13 April 2016. This paper surveys people, policy, business and change, farming systems for hill country, soil nutrients and the environment, plants for hill country, animals, animal feeding and productivity, and strategies for achieving sustainable outcomes in the hill country. This paper concludes by identifying approaches to: support current and future hill country farmers and service providers, to effectively and efficiently deal with change; link hill farming businesses to effective value chains and new markets to achieve sufficient and stable profitability; reward farmers for the careful management of natural resources on their farm; ensure that new technologies which improve the efficient use of input resources are developed; and strategies to achieve vibrant rural communities which strengthen hill country farming businesses and their service providers. Keywords: farming systems, hill country, people, policy, productivity, profitability, sustainability

<em>Local culture is very diverse Indonesia became an honor and challenge to maintain and inherited to the next generation. Local Indonesian culture is very proud because it has a very varied diversity and unique. As time, lead to changes in lifestyle a more modern society. As a result, people will prefer the new culture that may be considered more practical than the local culture. Views on kinship, treasures, and wander in the novel Tenggelamnya Kapal Van Der Wijck Hamka works and novels Bulan Susut works Ismet Fanany changes and cultural shifts. Kinship, treasures, and wander in the novel Sinking Ship Van Der Wijck Hamka's work is described explicitly, whereas kinship, treasures, and wander in the novel Month Losses Ismet work Fanany described implicitly. Changes in people's lives has implications for social Minangkabau culture in Minangkabau society. A leadership that is both functional mamak transformed into symbolic leadership. Mamak originally as straps tribesmen, has changed the status and intrinsic meaning.</em>

On the basis of automatic test system of the status in domestic and foreign, by analysis of the various functions and performance of the integrated test system, a design of the integrated test system is proposed, FPGA as the core logic controller of the hardware circuit. The system of the hardware design include: digital signal source output modules, analog output module and PCM codec module. Design of hardware circuit are mainly described. In addition, a detailed analysis of some key technologies in the design process was given. Overall, its data exchange with host computer is through the PCI card, data link and bandwidth can be expanded in accordance with the actual needs. The entire system designed in the modular principle, which has a strong scalability.

Abstract While the Antarctic Treaty System intended to keep Antarctica an area of international cooperation and science free from militarisation and international conflict, the region has not been completely shielded from global power transitions, such as decolonisation and the end of the Cold War. Presently, emerging countries from Asia are increasingly willing to invest in polar infrastructure and science on the back of their growing influence in world politics. South Korea has also invested heavily in its Antarctic infrastructure and capabilities recently and has been identified as an actor with economic and political interests that are potentially challenging for the existing Antarctic order. This article first assesses the extent and performance of the growing bilateral cooperation between South Korea and one of its closest partners, New Zealand, a country with strong vested interests in the status quo order. How did the cooperation develop between these two actors with ostensibly diverging interests? This article finds that what may have been a friction–laden relationship, actually developed into a win-win partnership for both countries. The article then moves on to offer an explanation for how this productive relationship was made possible by utilising a mutual socialisation approach that explores socio-structural processes around status accommodation.

In the last decade, there has been a surge in the number of academic research groups and commercial companies exploiting naturally occurring cosmic-ray muons for imaging purposes in a range of industrial and geological applications. Since 2009, researchers at the University of Glasgow and the UK National Nuclear Laboratory (NNL) have pioneered this technique for the characterization of shielded nuclear waste containers with significant investment from the UK Nuclear Decommissioning Authority and Sellafield Ltd. Lynkeos Technology Ltd. was formed in 2016 to commercialize the Muon Imaging System (MIS) technology that resulted from this industry-funded academic research. The design, construction and performance of the Lynkeos MIS is presented along with first experimental and commercial results. The high-resolution images include the identification of small fragments of uranium within a surrogate 500-litre intermediate level waste container and metal inclusions within thermally treated GeoMelt® R&D Product Samples. The latter of these are from Lynkeos' first commercial contract with the UK National Nuclear Laboratory. The Lynkeos MIS will be deployed at the NNL Central Laboratory facility on the Sellafield site in Summer 2018 where it will embark upon a series of industry trials. This article is part of the Theo Murphy meeting issue ‘Cosmic-ray muography’.
