Variable Message Format(VMF) is a communications protocol that allows computers to exchange tactical military information over low-data-rate bearers. VMF is designed to define message length and structure variably in order to allow the user to transmit only the relevant information by using indicators. However, flexibility of messages makes it difficult to analyze messages structure and figure out meanings. Furthermore, whenever messages are added or modified, message processing software should be updated and distributed to systems. In this paper, we propose a systematic approach to defining VMF messages that uses the international standard notation ASN.1. By describing VMF messages in ASN.1, protocol architects can deal with VMF messages accurately and conveniently, and use various ASN.1 tool. This paper develops ASN.1 description templates for VMF message segments, and presents an approach to describing VMF messages in ASN.1 by combining the templates.

Recently, as the importance of forced indoor living has increased in the untact era, the connection and relationship between space environments is increasing. That is, the smart interaction environment for providing services in various spaces collects and processes a number of surrounding environment information through various sensors to provide desired information according to the required place and time. In this environment, a new type of interaction paradigm is needed for the user to select and focus on environmental information. In this paper, we provide guidelines based on models and patterns for designing various interactions around space. Through interaction model-based technology, we provide guidelines for space-oriented interaction design. We propose an ideal interaction environment through guideline-based patterns and templates. Finally, by providing a space-oriented interaction environment suitable for smart interaction, users can freely obtain desired information.

This paper presents a method to generate three-dimensional AR/VR models using the information in Isogen data files (IDFs). An IDF is an output file produced by ISOGEN that contains piping isometric drawings. A piping isometric drawing is used for pipeline installation in the shipyard; therefore, the drawing describes assembly information with symbolic features, not with detailed geometric features. An IDF specifies relationships between piping routes and components with three-dimensional points and tag information as well as the bill of the materials of a pipeline. The key idea of this paper is that AR/VR models can be generated with the piping route points data and piping components tag information in real time, without any conversion of standard data exchange file formats, such as STP, IGES, and SAT. This paper describes IDF data structure and suggests the geometry generation process with IDF data and parametric functions.

In the 4th Industrial Revolution situation it is essential to need the high quality of software in diverse industrial areas. In particular current software centered schools attempt to educate the creative thinking based coding to non-major students and beginners of computer. But the problem is insufficient on the definition and idea of the creative thinking based software. In addition in a aspect of coding education for non-major and new students we recognize to have no relationship between creative thinking methods and coding. In other words we should give them how to practically code and design through learning the creative thinking. To solve this problem we propose the codification of design thinking mechanism without the knowledge of software engineering through mapping creative thinking with software development process. With this mechanism we may expect for students to have some coding ability with the creative design.

Today, companies exist amid unlimited competition and uncertain adminstration environment, so hands-on workers are being exposed to various job requirements and stress due to this. Especially, employees in the design firm are physically difficult because of heavy working intensity unlike other industrial field, and because the process is interrelated unlike working of a five-day workday of the other industry, it is difficult to guarantee periodic holidays and vacation. In addition, recently, while BIM is introduced in the construction industry, various changes in the individual role as well as organizational dimension such as business environment and scope & role, etc. are required, so it is the actual situation that the category and factors of job stress due to this are being also changed. Accordingly, this research has grasped important and weak sectors according to characteristics such as career, position, gender, education and existence/nonexistence of BIM template, etc. by confirming a job stress level and inducing factors of hands-on workers at the design firm. This research has a meaning in constructing a business environment of a design firm that is a main participant of BIM-based projects that are expected to have high utilization in the future.

The course of home economics education is the one that fosters the ability to solve life problems. The life problem is permanent involving the individual, family, and society in overall. Thus, this study was to compose a class which applied the backward design model suggested by Wiggins and McTighe focusing on the usability of it in the educational filed of the home science to overcome the limitation of the education in the filed based on that critical mind. Therefore, this study developed the teaching·learning plan applying the backward design model to the 'Food and Nutrition' unit of the home economics education. It is expected that the unit and the teaching plan are used as materials for the class on the dietary life unit which is meaningful for learners in the educational field of the home economics education.

The purpose of this study is to develop a model of the TOC (Table of Contents)-based research record system and to comparatively analyze its usability, in order to comprehensively and systematically manage and practically use the various research records generated from the entire process of research and development. For this purpose, the templates for technical recording and the components of each item were proposed to enable technical recording based on TOC, and structured contents were designed to organically connect between these TOC technical records and existing research records. Also, a database logical schema was developed to design a database, and a test collection was constructed on the basis of research records and TOC technical records. Finally, the model of research record system was constructed by designing TOC record search system and user interface including integrated search system. Based on this model, the usability assessment was performed by comparing the existing distributed general systems with the TOC-based research record system. As a result of the comparative analysis of these two systems, the TOC-based research record system showed generally higher utilization of research records than the general systems.

The flight test operational procedure artifact includes mission planning, execution methods, and safety measures for each step of test progress. As the development of guided missiles has become more advanced and strategic, flight test has become increasingly complex and broadened. Therefore, increased reliability of the flight test operation procedures was required to ensure test safety. Particularly, the design of the flight test operational procedures required verification through M&S to predict and prepare for the uncertainty in a new test. The relevant studies have published the optimal framework development for flight tests and the model-based improvements of flight test processes, but they lacked the specificity to be applied directly to the flight test operational procedures. In addition, the flight test operational procedures, which consist of document bases, have caused problems such as limitations of analysis capabilities, insensitive expressions, and lack of scalability for the behavior and performance analysis of test resources. To improve these problems, this paper proposes how to design operational procedure of guided missile flight test system by applying MBSE(Model-based Systems Engineering). This research has improved reliability by increasing the ability to analyze the behavior and performance of test resources, and increased efficiency with the scalability applicable to multiple flight tests. That can be also used continuously for the guided missile flight tests that will be developed in the future.

The purpose of this study was to identify the teaching methods used in inclusive music classes at elementary schools by of music in elementary school inclusive classes through the application of understanding by design and differentiated instruction, and to explore the feasibility of inclusive education. To this end, based on the 2.0 version of the backward design template, a unit for music lessons for 3rd and 4th grade inclusive classes was developed. The unit presented elements of differentiated instruction that considered students with intellectual disabilities at each stage. In the first stage, goals and essential questions were presented by analyzing the curriculum's achievement standards. In the second stage, a performance task was developed using the GRASPS technique, guidelines and examples were presented. Various evaluation methods based on students' readiness, interest, and learning type were suggested. In the third stage, the unit's seven lessons were planned using the WHERETO model. Examples of differentiated instruction for students with intellectual disabilities were presented by flexibly using classroom elements. This study indicated that understanding by design and differentiated instruction can be applied to inclusive education. Future studies on more diversified educational design and strategies are needed for promoting inclusive education.

A smart phone has functions of both telephone and computer. The wide spread use of smart phones has sharply increased the demand for mobile commerce. The smart phone based mobile services are available anytime, anywhere. In commercial transactions, a digital signature scheme is used to make legally binding signature to prove both integrity of commercial document and verification of the signer. Smart phones are more risky compared with personal computers on the problems of how to protect privacy information. It's also easy to let proxy user to authenticate instead of the smart phone owner. In existing password or token based schemes, the ID is not physically bound to the owner. Thus, those schemes can not solve the problem of proxy authentication. To utilize the smart phone as the platform of mobile commerce, a study on the new type of authentication scheme is needed where the scheme should provide protocol to get legally binding signature and not to authenticate proxy user. In this paper, we create the mobile ID by using both the USIM and voice template of the smart phone owner. We also design and implement the user authentication scheme based on the mobile ID.
