M2M can provide the bi-directional services between applications and objects which have the attached telecommunication module. It consists of the objects, platform, and (web based) applications. M2M can realize In-Transit Visibility and Asset Visibility combined with GIS. Although many applications of M2M, such as metering, monitoring, controlling, tracking et al., are being serviced, the interoperability among the M2Ms is not considered. In this paper, we described the interoperability. Specially, ROA, which is the state of art technology in mash-up, more than SOA, and URN, which is based on Open API in RESTful service, more than URL are studied. As the message protocol between platform and applications, MPM was defined.

KVMF(Korean Variable Message Format) 1.0 protocol is the Army's standard tactical datalink protocol that defines standard messages and communication methods to enable data communication between various weapon systems through bitwise variable message processing. The protocol has been applied to a variety of Army weapon systems over the past decade and has contributed to upgrade the Army's operational capabilities by enabling the implementation of Network Centric Warfare (NCW), the core of modern warfare. Since the KVMF 1.0 protocol was applied, new weapon systems with new technologies have been introduced over time, and new weapon systems have new messages based on the characteristics of the weapon system. As a result, compatibility problems arose due to different message versions with existing weapon systems, and it was expected that these problems would continue to emerge in the future, considering the need for continuous message revisions. Therefore, it became necessary to solve this problem, so this paper proposed a KVMF 2.0 protocol design that guarantees compatibility between forward and backward versions. In this paper, we implemented the design as SW, and confirmed that the design worked successfully by test between forward and backward versions on test environment. Therefore, when the KVMF 2.0 protocol design is applied to a weapon system, we can expect that the weapon system can be compatible with the forward and backward versions working with the existing weapon systems as well as with the future weapon systems.

In this study, it was investigated that the characteristics of startup and compatibility using several type hot and cold gases. The characteristics of starting LRE by pyro starter was compared with that by a Helium spinner. The compatibility of pyro gas, a gaseous Helium, Hydrogen+Nitrogen mixture gas, and air was investigated by a simple 1D turbine analysis considered the properties of each gas and turbine efficiency. Most of them were compatible to start up the LRE however air was properly used only for low power mode of turbine.

The rapid advancement of computing technology has triggered the need for fast data I/O processing and high-performance storage technology. Next generation memory technology, which we refer to as new memory, is anticipated to be used for high-performance storage as they have excellent characteristics as a storage device with non-volatility and latency close to DRAM. This research proposes NTL (New memory Translation layer) as a technology to make use of new memory as storage. With the addition of NTL, conventional I/O is served with existing mature disk-based file systems providing compatibility, while new memory I/O is serviced through the NTL to take advantage of the byte-addressability feature of new memory. In this paper, we describe the design of NTL and provide experiment measurement results that show that our design will bring performance benefits.

In this paper, I propose that what factors affect logistics companies' adoption of blockchain technology and to analyze the effects of blockchain technology on logistics performance. The variables influencing the adoption of blockchain technology were presented based on the TOE frame. Expected profit, organizational readiness, technology compatibility, and competitive pressure were suggested as factors to adopt blockchain technology. Also, as a blockchain technology, smart contracts and information transparency were presented. Logistics performance suggested agility and alignment. A survey was conducted with Korean logistics companies. Looking at the results of analyzing the collected data, it was found that expected profit and technology compatibility have a positive effect on this blockchain technology (smart contract, information transparency). Organizational readiness was found to have a positive effect on information transparency. Blockchain technology was found to have a positive effect on logistics performance.
