국방 시험평가 분야에서는 연구개발주관과 수요군에서 공공 및 민간의 시험시설을 사용하고 있으나, 다음과 같은 측면에서 효율적인 활용 방법을 제고할 필요가 있다. 첫째, 시험 시설･장비에 대한 정보, 활용절차 등 세부 현황이 시험시설을 보유한 기관별 독립된 정보체계에서 제공되기 때문에 사용자의 정보이용 수준에 따라 활용성의 차이가 있다. 둘째, 시험 서비스 제공 자와 수요자의 정보공유 필요성에 대한 인식의 불균형으로 시험시설을 효율적으로 활용하지 못하고 있다. 본 연구에서는 국방 시험평가의 효율성 향상을 위해 산재되어 있는 시험 시설･장비 정보를 통합하여 활용할 수 있는 방안을 제안하였다. 이를 위해 국방 시험평가와 관련 있는 공공 및 민간 시험시설･장비 현황을 파악하고, 설문 조사 및 인터뷰를 통해 획득한 사용자 요구사 항을 기초로 시험시설･장비 데이터베이스를 구축하였다. 본 연구는 그동안 개인의 노하우와 경험에 의존하여 공유가 곤란했던 암묵지 형태의 주관적이고 흩어진 시험시설･장비 관련 정보를 국방 시험평가 관계자가 쉽게 공유할 수 있도록 체계화한 형식 지 형태의 지식으로 변환했다는 데 의의가 있다. 본 연구결과가 국방 시험평가의 효율성 향상에 기여할 것으로 기대한다.

In the field of defense test&evaluation, research and development organizations and demand forces use both public and private test facilities. However, there is a need to improve methods for efficient use in several aspects. First, since each institution owning test facilities provides detailed information about facilities, infrastructure, and use procedures through its independent information system, usability varies depending on the user’s level of information proficiency. Second, test facilities are not used efficiently due to a lack of awareness regarding the importance of information sharing between test service providers and consumers. In this study, we propose a method to integrate and use dispersed test facilities and equipments information to enhance the efficiency of defense test&evaluation. To this end, we identified the status of public and private test facilities and equipments related to defense test&evaluation and established a database based on user requirements gathered through surveys and interviews. The significance of this study lies in its conversion of subjective and dispersed test facilities and equipments-related information, previously in the form of tacit knowledge that was difficult to share due to individual know-how and experience, into systematized explicit knowledge that can be easily accessed by defense test&evaluation officials. It is expected that the result of this study will contribute to improving the efficiency of defense test&evaluation.

In this paper, we have revisited the estimation of the rotational stiffness of sidewall of radial tire and have suggested a new method for evaluation of the rotational stiffness. Since thicknesses, and volume fractions of the constituents of sidewall are varied depending on radial position, the equivalent shear modulus of the sidewall also depends on radial position. For the estimation of rotational stiffness of sidewall's rubber, we have divided its cross-section into sufficient numbers of small parts and have calculated the equivalent shear modulus of each part of sidewall. Using the shear moduli of divided parts, we have obtained the rotational stiffness by employing in-plane shear deformation theory. This method is expected to be a useful tool in tire design since it relates such basic variables to the global stillness of tire. Applying the calculation method to a radial tire of P205/60R15, we have compared its rotational stiffness with experimental one.

Isatis tinctoria var. yezoensis (Ohwi) Ohwi (Cruciferae) is one of major natural dyeing crops in the world and also have used as a medicinal plant in Korea. We evaluated seed purity in F1-hybrid accessions using amplified fragment length polymorphism (AFLP) markers. One hundred sixty seeds from the male and female harvests were subsequently screened for seed purity with ten primers. The 13 accession-specific bands and many variable AFLP bands scored for accessions. Especially, E-AAC/M-CAA and E-AAG/M-CAT were presented clear hybrid bands for F1 hybrids. F1 hybrids maintained higher average level of genetic diversity compared with their correspondent parents. Self-inbred seeds from the female and male harvests were revealed 8.0% and 5.0%, respectively. The AFLP may lead to a better insight in to the hybrid seed purity test in I. tinctoria var. yezoensis.

This study aims to analyze engine performance and component characteristics of a micro gas turbine based on detailed measurement of various parameters. A test facility to measure performance of a micro gas turbine was set up and performance parameters such as turbine exit temperature, exhaust gas temperature, engine inlet temperature, compressor discharge pressure and temperature, and fuel and air flow rates were measured. The net gas turbine performance (power and efficiency based on the gas turbine shaft end) was isolated and analyzed. With the aid of measurement based simulation, component characteristic parameters such as turbine inlet temperature, compressor efficiency, turbine efficiency and recuperator effectiveness were estimated. Behaviors of the estimated characteristic parameters with operating condition change were examined and sensitivities of estimated parameters to the measured parameters were analyzed.

Purpose: Patients with diabetes frequently need to perform certain numeric tasks such as interpreting blood glucose levels. However, there is no psychometrically sound instrument for objectively measuring diabetes-specific health numeracy. This study aimed to develop a new objective diabetes health numeracy test (DHNT) and evaluate its psychometric properties in adult patients with type 2 diabetes. Methods: An instrument development study was conducted. Initial items were evaluated by six experts for content validity. After a pilot test, a convenience sample of 257 participants with type 2 diabetes was recruited at 2 university hospitals from May to September 2018. The structural, convergent, and criteria validity, and internal consistency of the DHNT with binary item responses were evaluated. Data were analyzed using exploratory factor analysis, Rasch analysis, tetrachoric correlation, Spearman's correlation, and the KudereRichardson-20 formula. Results: Exploratory factor analysis yielded a single-factor solution comprising seven items. Rasch analysis confirmed that no item did not fit with the single factor and identified that the item difficulty parameters had moderate values. The convergent and criterion validity of the instrument were demonstrated, with diabetes knowledge and subjective diabetes numeracy, respectively, as was its acceptable internal consistency, by a KudereRichardson-20 coefficient of .81. Conclusion: The DHNT demonstrated satisfactory psychometric properties. The instrument with moderate levels of item difficulty may have a lower cognitive burden. The developed instrument can be applied in practice to tailor the education of diabetes self-management as per the levels of health numeracy of specific patients.

Objective To identify factors affecting test results of the quiet standing balance evaluation conducted by posturography and to investigate the standardized method by comparing results according to feet width. Method Th e study cohort consisted of 100 healthy individuals. We assessed the quiet standing balance of subjects by using 3 diff erent methods: standing on a force plate with feet width the same as shoulder width (test 1); with feet width the same as half the shoulder width (test 2); with feet width determined by the subject’s comfort (test 3). Subjects underwent each test with their eyes open and closed for 30 seconds each time. Parameters for measuring standing balance included the mean mediolateral and anteroposterior extent, speed, and the velocity moment of center of pressure (COP) movement. Results All parameters showed better results when the subject’s eyes were open rather than closed, and the mean AP extent and speed increased as the age of the subjects increased (p<0.01). However, there was no signifi cant correlation between height and the study parameters, and no differences between men and women. Mean mediolateral extent and speed were signifi cantly longer and faster in test 1 compared with tests 2 and 3 (p<0.01). Th e results of test 2 were better than the results of test 3, but the diff erence was not statistically signifi cant. Conclusion COP movements increased with age and when subjects closed their eyes in an evaluation of quiet standing balance conducted by posturography. Gender and height did not aff ect results of the test. We suggest that an appropriate method for conducting posturography is to have the subject stand on a force plate with their feet width the same as half the shoulder width, because this posture provided relatively accurate balance capacity.

Chagas heart disease (CHD) leads to a progressive functional impairment. Field tests, as the 6-min walk test (6MWT) and the incremental shuttle walk test (ISWT), may be inexpensive approaches in the evaluation of functional capacity of these patients. The present study was addressed to compare the 6MWT and the ISWT measures, and to determine the accuracy of these tests in the identification of functional impairment in patients with CHD. Thirty-five patients with CHD (47.1± 8.2 years, NYHA I–III) were evaluated by echocardiography, cardiopulmonary exercise test (CPET), 6MWT, and ISWT. Correlations between the CPET (peak oxygen uptake [peak VO2] and the ratio between ventilation and the carbon dioxide production [VE/VCO2 slope]) and the field tests (walking distances) were also performed. The receiver operating characteristic (ROC) curve was selected to identify the best distances related to identify those patients with functional impairment. There was no difference between distances walked during the 6MWT and ISWT (P= 0.694). The Bland-Altman analysis showed good agreement between the field tests. Both 6MWT and ISWT correlated with peak VO2 (r= 0.577, P< 0.001 and r= 0.587, P< 0.001, respectively) and ISWT correlated with VE/VCO2 slope (r= -0.339, P= 0.003). The cutoff distances of 6MWT and ISWT to identify patients with peak VO2 less than 20 mL/kg/ min were 520 m and 400 m, respectively, with no difference between the areas under ROC curves (P= 0.276). Both the 6MWT and the ISWT demonstrated accuracy in identify functional impairment in patients with CHD, being useful tools for the risk stratification of these patients.

To review and systematically summarize the psychometric and clinical properties (reliability, validity, responsiveness) of the Timed Up and Go test applied to persons diagnosed with Parkinson disease. A systematic review was performed by screening four scientific databases (MED-LINE, CINAHL, and PubMed). Independent reviewers selected and ex-tracted data from articles that assessed the reliability, validity, sensitivity to change, and/or clinical properties of the Timed Up and Go test in per-sons with Parkinson disease. Twenty-four studies were selected. Nine analyzed reliability and yielded “good” to “moderate” scores. Seven-teen used a range of different contrast tests to assess validity of the Timed Up and Go test and found “good” quality scores in those that as-sessed balance. Only two studies analyzed sensitivity to change and they reported “poor” quality scores. The use of Timed Up and Go in Parkinson disease patients presents good reliability and validity (when compared to tests that assess balance).

The weapon systems development has some distinct characteristics in that a big size of government budget (derived from national tax) has been expended frequently and the completion of the development projects seems to take long. Thus, the impact of the potential changes in the required operational capability on the development activities can induce some type of project risks. As such, proper management of project risk has been one of crucial subjects in the weapon systems development. Although a variety of methods can be considered, an approach based on the test and evaluation (T&E) process has been selected in this paper in order to appropriately handle those potential risks. In the study of the underlying T&E process, the safety consideration (for instance, explosiveness) of weapon systems is also included. To achieve the objective of the paper, a step-by-step procedure is first presented in the analysis of the T&E process. Then, to pursue some enhancement on the process, a set of necessary and useful activities are added in terms of risk and safety management. The resultant process is further analyzed and tailored based on a design structure matrix method. The case study of a tank development is also discussed.

As weapon systems become complex in terms of the scale and functionality, the required time to complete the test and evaluation (T&E) process is inevitably getting longer. However, nowadays the reduction of T&E period becomes one of the core targets in the weapon systems acquisition programs. This is because the reduced time for T&E process can yield the reduction of defense budget and also faster deployment of the weapon systems, thereby having a competitive edge over rival countries. On the other hand, in weapon systems development the management of reliability, availability, maintainability and safety (RAMS), and risk is considered important to keep competitiveness and thus has been carried out separately. Thus, the objective of this paper is to study on improving the T&E process by integrating the RAMS and risk management process in it. To do so, the related processes are analyzed and modeled first. Then an integrated process model is developed. The resulting model is equipped with the traceability among the data and interfaces that are generated from the T&E and RAMS/risk processes. As a case study, the model developed is applied in tanks development. The effective use of the traceability is expected to reduce the time and cost required to complete T&E process.

Recent trends in rail industry can be characterized by the multifunctionality and very high-speed modes of operations. In particular, the adoption of the unmaned or operatorless operations has been getting increased attention in which case ensuring systems safety is crucial. On the other hand, according to the result of analyzing rail accidents, the human/operator errors have turned out to be one of the key causes of the accidents. Therefore, the effort of improving the work environment of locomotive cabs is quite necessary in order to decrease the accidents. The objective of this paper is studying on how to incorporate the factors related to the train operators in the design of the locomotive cabs and also on how to evaluate the design results obtained, which is subsequently reflected in the generation of the test and evaluation procedure. The approach taken is based on systems engineering, yielding the procedure document as a result. The results obtained in the paper can be useful in confirming the design of locomotive cabs utilizing the domestic human/operator measure. Also, the way of achieving the objectives can be utilized to cover the expanded rail systems development with appropriate design activities added.

최근 다양한 불특정 다수의 해킹 및 반복되는 DDoS 사이버테러 공격을 이해하고, 그 해결책을 비로소 공격 기법에서 찾을 수 있었다. 공격자와 방어자, 공격 기법과 방어 기법의 접목이라는 자유로운 연구 방식은 항상 엉뚱함에서 가능성을 발견해가는 도전이라 할 수 있다. 본 논문에서는“KWON-GA”라는 세계적인 화이트 해커들 개발진이 오랜 경험의 침투 및 진단을 통해, 공격이 최상의 방어라는 미명하에 방어의 목적으로 구현된 지식 정보 보안솔루션을 고객이 운용 중인 시스템 환경에 맞추어 필요한 기술을 적용하는 커스터마이징 정책으로 맞춤 솔루션을 제공할 수 있으며, 독창적인 원천기술로 처리되어 탐색이 불가능하고 내부적으로 유출되는 경우에도 분석이 되지 않아 해커에게 분석되어 취약점을 노출하거나 해킹의 수단으로 악용되지 않는 ITC융합 보안 솔루션을 시험평가 하였다.

국방 연구개발은 변화하는 미래 전장환경에 대응하기 위해 중․장기 소요로 결정된 무기체계를 확보하기 위한 핵심과정이다. 특히 시험평가는 무기체계 연구개발의 마지막 관문으로서 전력화 전환여부를 결정하는데 필요한 정보를 제공해주고 무기체계의 수명주기와 연계된 성능보장을 위해서도 중요한 역할을 수행한다. 한편 최근 한반도 작전환경 및 국방 획득환경의 변화를 살펴 보면, 크게 3가지 특징을 확인할 수 있다. 먼저 무기체계 전력화 운용시 지속적인 안전사고가 발생하여 전투원 안전에 대한 사회적 관심이 증대되었고, 획득비용의 증가에 따라 한정된 국방예산의 효율적 집행이 요구되고 있다. 또한 로봇․자율무기체계 (RAS), 사이버 보안 시험평가 등 미래 전장환경에 대응하기 위한 전략적 접근이 필요하다. 따라서 본 연구에서는 최근 변화된 안보환경의 특징을 고찰하여 무기체계 운용시험평가의 개선전략을 제시하고자 한다. 이를 위해 현행 무기체계 운용시험평가 시스템의 보완소요를 다차원 모형으로 분석하여 개선전략을 도출하였고 계층적 분석기법(AHP)을 통해 우선순위를 결정하였다.

Defense R&D is a key process for securing weapons systems determined by mid- and long-term needs to co pe with changing future battlefield environments. In particular, the test and evaluation provides information necessary to determine whether or not to switch to mass production as the last gateway to research and development of weapons systems and plays an important role in ensuring performance linked to the life cycle of weapons sys tems. Meanwhile, if you look at the recent changes in the operational environment of the Korean Peninsula an d the defense acquisition environment, you can see three main characteristics. First of all, continuous safety acc idents occurred during the operation of the weapon system, which increased social interest in the safety of comb atants, and the efficient execution of the limited defense budget is required as acquisition costs increase. In addition, strategic approaches are needed to respond to future battlefield environments such as robots, auton omous weapons systems (RAS), and cyber security test and evaluation. Therefore, in this study, we would like to present strategies for improving the testing and evaluation of weapons systems by considering the c haracteristics of the security environment that has changed recently. To this end, the improvement strategy w as derived by analyzing the complementary elements of the current weapon system operational test and evalu ation system in a multi-dimensional model and prioritized through the hierarchical analysis method (AHP).

최근 3000톤급 잠수함, 4.5세대 전투기 등의 첨단 무기체계가 국산화되고 있으며 다양한 무기체계의 수출이 크게 증가하 고 있다. 우리나라의 국방과학기술 수준은 세계 9위로 평가되고 무기체계 수출도 2020년 세계 9위로 평가되었다. 한편, 첨단 무기체계 기술을 노리는 사이버 공격도 증가하고 있어 방산업체의 기술보호 뿐만 아니라 수출용 무기체계의 기술 보호도 필 요성이 증가하고 있다. 2015년 제정된 방위산업기술보호법은 국방과학기술 중에서 보호가 필요한 기술을 방산기술로 정의하 고 방산업체의 방산기술보호 체계 구축을 강제화하고 있다. 그러나, 방산업체의 기술보호체계에만 초점이 맞추어져 있고, 수 출이 증가하고 있는 무기체계의 기술에 대한 보호를 위한 제도가 구체적이지 못하며 관련 연구도 무기체계 연구개발의 시험 평가 이전단계 까지로 시험평가분야는 전무하다. 본 논문에서는 무기체계의 방산기술 보호를 위한 방안으로 국방 무기체계 연구개발 절차에 적용할 수 있는 무기체계 안티탬퍼링 시험평가 프로세스를 연구하였다. 제안한 방법은 안티탬퍼링 시험평가 와 유사한 암호모듈의 시험평가 동향을 조사하여 보안요구사항 및 시험요구사항 등을 참고하여 안티탬퍼링 기술의 연구개발 후 시험평가를 하는데 필요한 조직 및 역할과, 단계별 행동절차 등을 포함하는 프로세스를 제안하였다.

Recently, advanced weapon systems such as 3,000-ton submarines and 4.5-generation fighter jets are being localized, and exports of various weapon systems are increasing significantly. Korea’s defense science and technology level was ranked 9th in the world, and arms system exports were also ranked 9th in the world in 2020. Meanwhile, cyberattacks seeking advanced weapon system technology are also increasing, increasing the need for technology protection of export weapon systems as well as technology protection of defense companies. The Defense Industry Technology Protection Act enacted in 2015 defines defense technology as defense technology that needs protection among defense science and technology and enforces the establishment of defense technology protection systems for defense companies. However, there is no system to protect the technology of the weapons system, which is increasing in exports, and there is no test evaluation field until the pre-test evaluation stage of weapons system research and development. In this paper, as a way to protect the defense technology of weapons systems, we studied the weapon system anti-tamping test evaluation process applicable to the defense weapons system research and development process. The proposed method investigated the test evaluation trend of cryptographic modules similar to the anti-tampering test evaluation, and proposed a process including the organization and role necessary for the test evaluation of anti-tampering technology after research and development by referring to security requirements and test requirements.

The C-ITS requires the lane level positioning of the vehicle in the land transportation environment, and it is most effective to utilize the GNSS. In the precision positioning system based on satellite navigation, the evaluation of dynamic environment of lane level positioning performance should be accompanied and the evaluation system configuration should be preceded. In this paper, we selected performance indicators, assessment equipment, and reliability of reference equipment for evaluation of precision positioning user systems based on the GNSS. The performance evaluation system described above is applied to a real system, and the performance evaluation tool developed for the evaluation system is described. The numerical performance evaluation was carried out based on the data collected by carrying out the actual testbed driving. The performance evaluation by the actual driving trajectory and driving image comparison was performed to derive and analyse the evaluation results of the vehicle lane level positioning user system.

A multi-purpose polariscope is developed by applying an electro-mechanical control system to a diffused transmission-type circular polariscope. A conventional polariscope is only good for manual control of optical elements. The new polariscope system is devised to be controlled through two stepping motors and two magnetic clutches. The developed system has both functions of a conventional linear- and circular-polariscope. The new polariscope can be used not only for the point-wise measurement using Tardy compensation technique but also for the full-field fringe analysis using conventional and/or phase measuring techniques, if applicable.

아스팔트 혼합물의 균열 저항성은 일반적으로 인장 강도, 스티프니스와 같은 단일 물성치를 측정함으로써 평가된다. 그러나, 아스팔트 혼합물의 균열 성능을 평가함에 있어서 단일 물성치의 이용은 의문시되어 왔다. 따라서 본 연구에서는 아스팔트 혼합물의 균열 저항성과 관련이 있는 주요 특성치를 좀 더 심도 있게 규명하고자 하였다. 이를 위해 다양한 하중 조건 하에서 파괴 시험 크리프 시험, 강도 시험이 일반 아스팔트 혼합물과 개질 아스팔트 혼합물에 대해서 수행되었다. 시험 결과, 혼합물의 균열 저항성은 주로 미세 손상 축적 속도에 영향을 받음을 알 수 있었으며, 이 값은 파괴 에너지 한계에 영향을 주지 않으면서 m값에 반영됨을 알 수 있었다. 또한, 짧은 하중 재하 시간 (탄성거동) 동안 얻어지는 스티프니스는 혼합물의 균열 저항성의 차이를 규명하는데 한계가 있음을 알 수 있었다. 따라서 아스팔트 혼합물의 균열 저항성을 보다 명확히 평가하기 위해서는 혼합물의 크리프 거동과 파괴 한계점을 동시에 고려하는 것이 필수적임을 알 수 있었다. 또한 수퍼페이브 간접 인장 강도 시험으로부터 구한 잔여 소멸 에너지는 비교적 손쉬운 실험을 통해 아스팔트 혼합물의 균열 저항성의 상대적인 차이를 보여줄 수 있는 유용한 물성치임을 알 수 있었으며, 장기 크리프 시험에서 얻어지는 파괴 변형률은 아스팔트 혼합물의 크리프 거동과 파괴 한계점을 동시에 고려함으로써 균열 저항성을 평가할 수 있는 유용한 물성치 임을 알 수 있었다.

The cracking resistance of asphalt mixtures is generally evaluated by measuring a single parameter (i.e., Tensile strength, Stiffness). However, the use of a single parameter has been questioned in the evaluation of asphalt mixture cracking performance. The focus of this study was to clearly identify the key properties and characteristics associated with the cracking resistance of asphalt mixtures. Results of fracture, creep, and strength tests at multiple loading rates performed on the modified and unmodified mixtures showed that the mixture cracking resistance was primarily affected by the rate of micro-damage accumulation. This was reflected in the m-value, without affecting the fracture energy limit. It was also observed that the short loading time (elastic) stiffness alone could not differentiate the mixture cracking resistance of the mixtures. It was concluded that the key to characterize the cracking resistance of asphalt mixture is in the evaluation of the combined effects of creep and failure limits. It was also found that a residual dissipated energy parameter measured from Superpave IDT strength test gave the quick and useful way to distinguish the difference of cracking resistance of asphalt mixtures. Failure strain in the longer-term creep test appeared to be a useful parameter for evaluating the combined effects of creep and failure limits of asphalt mixtures.

The RWR (Radar Warning Receiver), an Aircraft Survivability Equipment (ASE), is used to detect, analyze, find directions and identify electrical threat signals and threat warning to the operator. Test and Evaluation must to be conducted in order to verify the performance of the RWR system. It is necessary to test and evaluate RWR’s sensitivity, dynamic range, signal type, direction finding accuracy and interface with other systems. Results are evaluated to assess progress in design, performance, supportability, and so on. There are two kinds of Test and Evaluation: Developmental Test and Evaluation (DT&E) and Operational Test and Evaluation (OT&E). DT&E focuses on the technological and engineering aspects of an RWR system, while OT&E is the actual or simulated employment of RWR under realistic operational conditions. The purpose of Test and Evaluation Support Equipment is to determine how well an RWR system works. This article introduces a Test and Evaluation support equipment product design for an RWR system.
