Technology transition from defense technology to weapon system is an important process for defense acquisition program. Many countries such as USA, UK, Australia and Republic of Korea use technology readiness level (TRL) as a tool for technology transition by identifying critical technology elements (CTEs) and assessing the technology maturity. In this paper we review a transition process for the defense acquisition. Then we suggest a method to evaluate system's TRL using each component TRL and integration readiness level (IRL) between each technologies. We apply the method to an ACTD project. A result show that technology maturity is influenced by integration between technologies.

The long-life housing certification system must have been applied more than 1,000 households apartments since 2015. The basic design guideline for the popularization of long-life housing has been developed in 2017, which include the concept of long-life housing and basic principle of design long-life housing. The demonstration project of long-life housing is be currently under construction in Sejong-si. The aim of this study is to find items on design checklist considering construction stage. The main goal is the development of design manual of long-life housing.

In executing the large scale national project, such as development of space launch vehicle, it is most important to guarantee the technological reliability. However the reliability analysis of launch vehicle is different from other mass product goods because of the limitation of budget and number of tests. In this study, the reliability analysis technique of the propulsion system, which is one of the major sub-systems of launch vehicle is illustrated and applied to the liquid rocket engine of KSR-III.

In this paper, in order to reduce the electrical disaster damage which is caused by with electrical equipment of traditional markets, we developed the cabinet panel and the electrical safety monitoring system which is able to monitor the electrical equipments condition(over current, leakage current, arc, WH, electrical fire factor etc.) at traditional markets. We constructed Test-bed for testing reliability of electrical safety monitoring system and cabinet panel. And we tested the cabinet for over current, leakage current and arc under the traditional markets actual condition. This paper will be used with the data for an demonstration project after compensating the defects which are occurred to operation of traditional markets actual loads.

Compared with existing construction materials, ACM(Advanced Composites Material) possesses many advantage such as light-weight, high-strength, corrosion resistant properties, etc. In this study, utilizing those advantages of ACM, composite skin and comer plate for protection of concrete port structure are developed. Detailed procedure fur analysis, design and fabrication along with site installation for demonstration project are described. It is also demonstrated that pultrusion process for comer plate and VARTM process for composite skin are promising fabrication methods fer future civil infrastructure application.

This paper aims at enhancing the electric production efficiency of photovoltaic(PV) system. The electrical power of PV system is proportional to light intensity on a PV module surface. In this paper, we apply two types of systems to enhance power generation efficiency. First, of all, concentring sunlight using specular surface and one-axis tracking system which traces the sun with vertical direction are applied in this project. From this, we analyze the fixed type method and power generation efficiency.

The direction of this project is creates a future and it experiences ubiquitous world. The subject of the space is 'Ubiquitous Creative World' which Imagining the past becomes actuality and imagining in future become actuality and future when it will approach at once. The storyline of this space is as belows; 1 Zone - Ubiquitous life Gallery : it will be able to experience the future world ; home, office, street, school and the others. 2 Zone - Interactive Play Gallery : it will be able to explore the interactive media with information technology ; digital cafe, imagining jump, digital art and the others. 3 Zone - New product and Business Gallery : it composed with business, new product, and demonstration gallery such as public information space. The space concept makes connection and concentration which uses unit and line for world which becomes accomplished by the network. Connection of digital and the human being to make the center of new digital life.

In modern society, the use of small rotary-wing unmanned aerial vehicles such as drones is increasing. As the military considers tactics using drones, demand for drones is increasing. However, there is still no airworthiness certification standard for drones for safety. In this paper, we proposed airworthiness certification standards for small rotorcraft unmanned aerial vehicles based on CS-LURS in Europe and STANG-4703, 4738 (draft) of the North Atlantic Treaty Organization. In addition, airworthiness certification standards have been strengthened through the case of unmanned aerial vehicle accidents in operation by the Korean military. The airworthiness certification standards for small rotary-wing unmanned aerial vehicles will be supplemented through a demonstration project.

Both access to healthcare services and income security in case of personal illness are being needed to achieve universal health coverage, which is enshrined in the human rights to health and social security and international standards on social protection. Income security acts on both the social determinants and the adverse consequences of ill health and thus would break the vicious disease-poverty cycle. The government is supposed to implement a demonstration project of sickness benefit in 2022 and to publicize its more specific blueprint for all workers. This study is to suggest basic principles and a framework to design a new sickness benefit for universal health coverage, which is based on reviews on previous studies, related issues, and institutional conditions. This is to provide a theoretical basis to promote further discussion and to support its decision-making.
