물류 표준화의 핵심은 수송, 보관, 포장, 상/하역, 정보/보안의 물류활동간의 호환성과 연계성의 확보이다. 국제표준 채택을 의무화하고 있는 WTO/TBT 협정을 차치하더라도 물류표준화의 정도는 국가의 물류경쟁력을 결정짓는 가장 중요한 척도라고 할 수 있다. 특히 한 중 일 3국의 경우 교역랑만 5조 3,236억불로 전 세계 교역량의 17.6%(2010년 기준), GDP 합계 12조3443억 달러로(2010년 기준) 세계전체 GDP 62조 9093억 달러 중 19.6%, 해운물동량은 전 세계 물동량의 60% 이상을 차지하고 있는 상황에서 물류경쟁력은 곧 국가경쟁력으로 보아도 무방하다. 아직도 국내에서는 물류분야 간 연계와 첨단정보기술이 결합된 현장중심의 융 복합 표준이 미비하고 대부분의 경우 해외국가들이 자신들의 입장대로 추진하거나 선점한 표준을 따라가기 바쁜 실정이었다. 스마트물류표준화는 이러한 현실에서 탈피하여 글로벌 물류표준을 선도하고 국내 현실에 적합한 현장물류표준을 반영하자는 취지에서 출발한다. 스마트물류는 i-ULS(Intelligent-Unified Logistics System) 체계, 즉 IT와 각 물류기술을 융합하여 표준화시키는 것은 물론 기존 표준을 산업현실에 맞게 반영해 나가는 것이 국가표준코디네이터로서의 주요한 목표가 되고 있다. 본 고는 전년도 스마트물류 표준화로드업에 작성된 표준화기술 중 산업체 설문을 통하여 10대 주요 표준화 트렌드를 선정하여 정리한 것이다. 10대 표준화 기술로는 순환물류포장시스템, 실시간 위치추적기술, 스마트컨테이너(Smart Freight Containers), 해상용 컨테이너 모니터링 시스템(CTMS), 글로벌 포장 표준모듈, 친환경물류 표준지표, 스마트물류 포장용기, 스마트그린물류센터(Passive Warehouse), 모바일 RFID 물류 적용 기술, Modal Shift(전환교통) 등이 선정되었다. 이번 4월호 특집에서는 10대 표준화 전략트렌드 가운데, 스마트물류에 대해 알아보도록 한다.

Avionics technologies have been developed with a development of an airplane since 1903. Historically, radio communication was started in 1910's, radio navigations in 1920's and autopilot was applied first in 1930's. Glass cockpit was initiate on MD-80 in 1979 first and now spreaded widely and similar with GPS navigation. Avionics in modern aircraft has a great deal of importance in view of flight safety and maintaining comfortableness. As avionics develops, so do the certification technologies. This paper introduces update avionics certification technologies developed recently.

Assembly process data can be gathered in real time in a manufacturing execution system (MES) server using proximity sensors, barcodes, RFID, ZigBee, Bluetooth, wireless sensor networks, etc. Although this is suitable for identifying process flow and checking production progress, it is difficult to trace the location of individual workers in real time for missing work or trajectories within the work area. To overcome this, the location and trajectory of the working tool can be analyzed in real time through a position tracking system of an operator's working tool. It can instruct the operator to perform a consistent working process. Productivity and quality improvement can be achieved by an alarming or blocking operator with possible assembly defects during the assembly process in real time. To this end, we developed a real-time tool position-tracking sensor system based on Ultra Wide Band (UWB) trilateration using a Kalman filter to eliminate mechanical vibration and radio communication noise.

As Internet of Things (IoT) technology advances, there is a growing demand for location-based services (LBSs) to identify users' mobility and identity. The initial LBS system was mainly used to measure position information by measuring the phase of a signal transmitted from a global positioning system (GPS) satellite or by measuring distance to a satellite by tracking the code of a carrier signal. However, the use of GPS satellites is ineffective, because it is difficult to receive satellite signals indoors. Therefore, research on wireless communications systems like ultra-wide band (UWB), radio frequency identification (RFID), and ZigBee are being actively pursued for location recognition technology that can be utilized in an indoor environment. In this paper, we propose an LBS system that includes the 2.45GHz band for chirp spread spectrum (CSS), and the 3.1-10.6GHz band and the 250-750MHz bands for UWB using the IEEE 802.15.4a standard for low power-based location recognition. As a result, we confirmed that the 2.45GHz Industrial, Scientific and Medical (ISM) band RF transceiver and the ranging function can be realized in the hardware and has 0dBm output power.

This Study seeks for a plan for promotion of smartification of digital services for improving convenience in use and user services of public libraries in smart digital environment. Thus, in this Study, a survey on awareness of a plan for revitalization of digital data and smart libraries has been conducted for the persons in charge of digital data and librarians from public libraries. The result of this Survey are as follows: first, the introduction of smart libraries was effective by first implementing them in small and medium-sized cities with high interest in in information technology, and spreading them to public libraries in metropolitan cities and special autonomous cities; second, it is analyzed that the essential factor of success in introduction of smart libraries is the contents free from the terminals and the upgrade of computer equipment of users available for the use of these services. Terminals are to be individually utilized by smartphone users but it is necessary for upgrade and introduction of 5G which can secure the mobility of users including open type Wi-Fi; third, it is discovered that the information technology the applicability of which is expected to be easy while introducing smart libraries is RFID, which has been already generalized, and bigtata technology. The introduction of IoT technology in which the stakeholders of public libraries in metropolitan cities and special self-governing cities must be considered first.

In this study, trends in research methods and topics of seabird and marine fish migration were examined. Based on the framework of existing animal migration studies, future research directions were proposed in relation to the migration of seabirds and fish. In terms of research methodology, with the development of science and technology, tracking techniques using radio telemetry, acoustic telemetry, RFID (radio-frequency identification), satellite tracking, and geolocators are widely used to study seabird and fish migration. Research is also conducted indirectly through a population survey and the analysis of substances in the body. Research contents are largely classified into extrinsic factors that affect migration(such as environmental variables and interspecific competition), intrinsic factors such as hormones, anthropogenic activities including fishery and offshore wind farm, and the effect of global climate change. In future studies, physiological factors that influence or cause migration and dispersal should be identified concerning intrinsic factors. For the analysis of migration ability, it is necessary to study effects of changes in the magnetic field on the migration ability of seabirds and fish, interspecific differences in spatiotemporal migration ability, and factors that influence the migration success rate. Regarding extrinsic factors, research studies on effects of anthropogenic disturbances such as fishery and offshore wind farm and global climate change on the migration and dispersal patterns of marine animals are needed. Finally, integrated studies on the migration of seabirds and fish directly or indirectly affecting each other in various ecological aspects are required.

To improve the pot life of one-part in-house anisotropic conductive paste (ACP) formulations, 2-methyl imidazole curing accelerator powders were encapsulated with five agents. Through measuring the melting point of the five agents using DSC, it was confirmed that a encapsulation process with liquid-state agents is possible. Viscosity of ACP formulations containing the encapsulated imidazole powders was measured as a function of storage time from viscosity measurements. As a result, pot life of the formulations containing imidazole powders encapsulated with stearic acid and carnauba wax was improved, and these formulations indicated similar curing behaviors to a basic formulation containing rare imidazole. However, the bondlines made of these formulations exhibited low average shear strength values of about 37% level in comparison with the basic formulation.

In this paper, we propose ubiquitous tree management system based on GIS and smart-phone using the object-oriented design modeling to maximize the efficiency of tree management. For this, proposed system is implemented in the form of client/server (C/S). The spot tree management system as the client is based on the mobile(PDA, Smart-Phone), whereas the tree management system based on PC as the server makes use of GIS. Also, Web service method instead of CDMA used in exist studies is used for tree data communication among C/S. And problems of existing studies, that is excessive maintenance costs, accessibility shortage of variety users, connectivity shortage of geographic information system will be settled through the convergence of the proposed system development methods, GIS system, smart devices. Therefore, we verify proposed system by using the systemic unit test and qualitative assessment respectively and prove to be more excellent than the existing system based on the mobile, in terms of systemic effectiveness and extendability.
