AUTOSAR is a partnership of automotive manufacturers and suppliers working together to develop and establish a de-facto open industry standard for automotive software architectures. In the AUTOSAR architecture, the runtime environment is at in the heart of the AUTOSAR architecture to provides the infrastructure services that enable communication between software components and between software components and basic software components. The RTE generator is an automated generation tool for AUTOSAR specification based RTE according to the ECU configuration. It generates communication API function for the software components and the basic software components like OS and COM of the application. The availability and the accuracy of the RTE generator are important for the automobile software which is based on AUTOSAR architecture, this paper proposes an architectural design of the RTE generator for auto-generation of the AUTOSAR based RTE.

With the increase in the risk of GPS jamming, the development and application of anti-jamming GPS techniques have been actively performed. As the objective performance verification of developed techniques is important, equipment development for verification and discussion on anti-jamming performance test method and procedure have also been conducted. However, most tests are related to the specification of equipment and therefore detailed procedure of the performance verification of an anti-jamming system needs to be developed. In this study, requirements for anti-jamming performance verification were described, and test configurations and performance evaluation items depending on three kinds of test methods (lab test, basic outdoor test, and chamber test) were suggested for anti-jamming performance verification.

The Korea Association of Medical Colleges (KAMC) has been developing learning outcomes for basic medical education (BME) since 2012. This initiative is designed to help medical schools implement competency-based medical education. KAMC divided the BME competencies into three domains (clinical practice, scientific concepts and principles, and human beings and society) with learning outcomes for each domain. KAMC plans to revise the learning outcomes to reflect feedback from medical schools, changes in social health needs, and changes in the healthcare environment and healthcare system in the near future. KAMC also plans to specify learning outcomes that integrate the three domains.

In this study, various railroad geotechnical informations were standardized. The standardization was progressed by classifying the informations as basic properties, railroad vibrations and design plans. Basic informations included soil properties(27), dynamic property(1), geophysical prospecting(1), and elastic wave prospecting(4). Specification for 'human exposure to whole-body vibration' was used to construct the information of railroad vibration. And in the case of the information of design plan, the way to save by graphic files was chosen. Thus standardized informations examined their application by setting up database. Entity-Relation(E-R) model was used in the design of database and by this, the database system was constructed. This database system will be able to serve the performance enhancement of railroad system.

As a train control system becomes a large scale and complex, it is necessary to control rigorously the system requirements specification of the train control system at the early phase. This paper describes Use Cases and activity diagrams of ATS functions requirements in the train control system. Basic functions of the train control system refers to IEC 62290-land are suggested. And the basic functions includes train operation without a driver. It is anticipated that this paper will be helpful for the analysis of ATS functions, ATO functions and EI function in the train control system.

This is the first report about the development of INMARSAT-C Satellite communication terminal. We analyze the existing Inmarsat-C terminal and examine each rules(IMO rule, domestic rules) about terminal. With that result, we design the basic hardware and software of terminal. This report consists of ; 1) the contents of the overall of operating situation and resources of INMARSAT-C system as like operation of communication system, communication channels and services 2) the contents of the specification of Inmarsat-C terminal hardware and software and the rules of IMO and Type approval 3) the design of basic hardware and reserch of signal modulation/demodulation using Viterbi algorithm 4) the design of software algorithms and functions focused in korean situations.

This study evaluated wind loads considering a local basic wind velocity and construction periods to define the level of applied wind loads for system supports. Structural responses of system supports were examined and compared to those of system supports with the level of wind loads following various standards and specifications for permanent and temporary structures. And, the maximum combined stress ratios were estimated to evaluate the structural safety of a considered system support. From results, it was found that the wind load level should be applied in accordance with construction periods when estimating the safety of system supports. Looking into the response by change of the basic wind velocity according to local regions, it is no need to consider wind loads in regions with the basic wind velocity of 30 m/s. However, it was analyzed that wind loads should be considered in the regions with the basic wind velocity of 40 m/s or above. In addition, wind loads should be considered in designing system supports located at the region with the basic wind velocity of 35 m/s starting from construction period of 1.5 years. The standard specification for temporary work was analyzed as an incorrect standard in evaluating wind loads, since it underestimated the response of system supports in accordance with the local basic wind velocity and construction periods.

The Basic Semantic Register(BSR) is and official ISO register designed for interoperability among eBusiness and EDI systems. The entities registered in the current BSR are not defined in a machine-understandable way, which renders automatic extraction of structural and relationship information from the register impossible. The purpose of this study is to offer a framework for designing an ontology that can provide semantic interoperability among BSR-based systems by defining data structures and relationships with RDF and OWL, similar meaning by the 'equivalentClass' construct in OWL, the hierachical relationships among classes by the 'subClassOf' construct in RDF schema, definition of any entities in BSR by the 'label' construct in RDF schema, specification of usage guidelines by the 'comment' construct in RDF schema, assignment of classes to BSU's by the 'domain' construct in RDF schema, specification of data types of BSU's by the 'range' construct in RDF schema. Hierarchical relationships among properties in BSR can be expressed using the 'subPropertyOf' in RDF schema. Progress in semantic interoperability can be expected among BSR-based systems through applications of semantic web technology suggested in this study.

The general requirements to achieve the structural integrity of the airframe are described in the military specification, MIL-STD-1530A. One of these requirements is the durability and damage tolerance of the airframe, which should be shown through the analysis and test based on the related specifications. This paper introduces the full scale durability test to evaluate the structural safety and durability of the basic trainer, KT-1. The test was performed according to the procedure in the military specification. The flight by flight load spectrum was developed by KT-1 fatigue load criteria and used for the durability test. The durability test had been performed for 4 service lives and was completed successfully. Therefore, it was shown that KT-1 airframe satisfied the durability requirements.

Simulation Framework is a basic software tool used to develop simulation applications. This paper describes the development of a discrete event simulation framework based on DEVS(Discrete EVent System Specification) formalism, using MATLAB language which is widely used in technical computing and engineering disciplines. The newly developed framework utilizing MATLAB object oriented programming combines the convenience of MATLAB language and the sophisticated architecture of the DEVS formalism. Hence, it supports the productivity, flexibility, extensibility that are required for the simulation application software development of the weapon systems engagement. Moreover, it promises a simulation application the increased the computation speed proportional to the number of CPU of a multi-core processor, providing the batch simulation functionality based on MATLAB parallel computing technology.
