This paper includes an example of applying Six Sigma to Non-function test process to improve the efficiency and reliability of the Ammunition Stockpile Reliability Program (ASRP). By applying the DMAIC which is one of the Six sigma methods. we found out the vital few and as an improved version : effective redesign of check-sheets, pre-examination of technology, on-the-scene support system. As a result, we could enhance the reliability and reduce manpower and additional expenses.

The blanking interface between an ES system and a radar system on the same platform cause the unwanted radar signal separation in the process of the signal measurement of the ES system. In this paper, we propose the novel radar signal blanking method for ES. The proposed method extracts a standard of judgement which we can decide whether a radar signal is separated by the blanking interface and presents how to merge the separated signals. Test result is presented to show the performance of the proposed method.

The Korean Society of Radiology and the National Evidence-based Healthcare Collaborating Agency developed a primary imaging test for suspected traumatic thoracolumbar spine injury. This guideline was developed using an adaptation process involving collaboration between the development committee and the working group. The development committee, consisting of research methodology experts, established the overall plan and provided support on research methodology. The working group, composed of radiologists with expertise in musculoskeletal imaging, wrote the recommendation. The guidelines recommend that thoracolumbar spine computed tomography without intravenous contrast enhancement be the first-line imaging modality for diagnosing traumatic thoracolumbar spine injury in adults.

교포사회에서 한국어 방송국은 현지 교포들과 모국에 대한 정보를 전달하는 중요한 매개체로써 재외 교포들 간의 문화공동체 발전과한민족 정체성확립에중요한 인프라역할을 한다.[1] 하지만 이러한 역할과는 별개로 현재 대부분의 해외 한국어 방송사들은 운영에서부터 제작환경에 이르기까지 많은 어려움을 겪고 있어 그 미래를 긍정적으로만 볼 수 없는 실정이다. 이에 본고에서는 현재의 해외 한국어 방송 지원 사업에 대해 조망하고 효율적인 정부지원방안에 대해 모색하려 한다.

As the number of data and devices explodes, centralized data processing and AI analysis have limitations due to the load on the network and cloud. On-device AI technology can provide intelligent services without overloading the network and cloud because the device itself performs AI models. Accordingly, the need for on-device AI technology is emerging. Many smartphones are equipped with On-Device AI technology to support the use of related functions. In this paper, we compare software tools that implement On-Device AI.

최근 IT(Information Technology)와 타(他)산업 간의 융 복합이 촉진되면서 새로운 융합서비스로 사물지능 통신(M2M, Machine to Machine)이 차세대 지능형 인프라 기반의 핵심 서비스로 부각되고 있다. 사물지능 통신은 기존의 통신 인프라를 활용하여 사물정보의 수집, 가공, 처리를 통해 최종 서비스를 제공하는 기술 분야로 PHY, MAC, 라우팅에 대한 기술 이슈보다는 서비스 관점에서의 네트워크 아키텍처 정의와 기능, 서비스 플랫폼 간의 연동, M2M 단말과 네트워크 간의 인터페이스에 대한 연구가 진행 중이다. 본 논문에서는 사물지능통신 융합서비스를 사용자에게 보다 편리하게 제공하기 위한 기존 플랫폼 간의 연동을 위한 요구사항과 방안을 제안한다.

Purpose: This study is aimed at developing of the flex resistance testing process at low temperature with the waterproof fabric to suit the military environment, and is designed to fit for the purpose of the waterproof materials in order to optimize the test method by finding out matters to improve from existing the test method and through previous studies. Methods: The test method, which has been applied to flex resistance of existing water-repellent materials, was improved and consequently, differentiated test results could be obtained according to the test temperature, sample size, and flexing method. Results: The testing of the total of 8 samples revealed that performance of the military requirement could hardly be met just by presenting the materials or 2~3 layers when the quality criteria for high functional water repellent fabrics were applied. PTFE(Polytetrafluoroethylene) is preferred to PU(Polyurethane) to be used in the extremely low-temperature environment, but durability under the low-temperature environment may be varied depending on film thickness or laminating technique even if the materials of waterproof films are identical. Therefore, in addition to the material or texture, the test method capable of reflecting durability under the low-temperature environment shall be suggested, and the newly designed test method proposed in this study was shown to suggest differentiated quality criteria by the material. Conclusion: The water resistance measurement and the test method following flex resistance with expanded range of flex will enable the differentiable test of the samples according to the number of repetition. This study is meaningful in that it suggests a differentiable test method capable of establishing a basis of deciding suitable material when selecting military goods made of water repellent material by properly improving the test method.

The aim of this study is to estimate the recognition of ex-prisoners and experts on rehabilitation programs and family support programs by Korea Rehabilitation Agency, which plays a responsible role in promoting social reintegration. Estimation and comparison method was used to assess between the efficiency and the importance of the rehabilitation business which was respectively recognized by ex-prisoners and experts. The subjects of this study who have received the support from the agency were composed, and the effectiveness was identified. In addition, to measure the importance of the rehabilitation business, a group of experts were made up of professors, the agency employees, and correctional officers with expertise and experience of this field of reintegration and recidivism. Collected data were shown in quadrants by setting preference and importance on each axis through IPA. As a result, there was a significant difference between the preference and importance, and based on this result, the discussion was suggested in relation to the rehabilitation business and family support business.

Fastener tapes are widely used as auxiliary materials in textile products, and military textiles products are also applied. However, in Korea, the HL3-WA class of KS K 1309 was applied to military uniforms without consideration of the operating environment. Instead of adopting the standard of initial strength for Korean military uniforms, the US military applied the value after 3 washings, and presented different properties according to the items. Also in Japan, the standard was applied differently according to products in general clothing. The purpose of this study in to examine the quality level of fastener tapes used for military materials. The changes of tensile shear strength and peel strength of military and commercial fastener tape were studied after washing. As a result, the initial strength of the current military fastener tapes was higher than commercial one, but the strength retention rate was rapidly decreased as the number of washing. So it was confirmed that the decrease in strength was relatively lower than commercial one. It is necessary to improve the durability by adjusting the adhesive strength to suit the purpose of the product, and it is necessary to consider the priority of maintaining the durability according to the initial performance and repeated use according to the use environment, respectively.

This study examines the supervision competence of supervisor from the comparative perspective of supervisor and supervisee, and investigates the effects of organizational factors on supervisor's supervision competence. For this purpose, data collected from 241 workers at social welfare agencies in Gyeonggi-do were analyzed through t-test and hierarchical regression analysis. The major results of data analysis are as follows. First, supervisors are more positive than supervisees in terms of supervision competence. Second, there is a statistically significant difference between two groups in supervision knowledge and qualities among the subfields of supervision competence. Third, in the case of supervisors, the younger the age and the higher the education level, the more positively they perceive their supervision competence, and agency's supervision support explains supervision competence at the level of △R² = .305 at p> .001. Finally, based on the results of this study, the directions for strengthening the supervision competence were suggested.
