선형적인 읽기와 쓰기 특성을 가지고 있는 승자전취메커니즘 방식의 아날로그 메모리를 구현하였다. 메모리의 읽기 동작은 연상메모리의 최적 함수 선택을 위하여 절대값 회로와 승자전취메커니즘 회로가 이용된다. 본 연구에서는 병렬의 고속 쓰기와 읽기 동작뿐만 아니라 고집적을 가능하게 하는 시스템 구성이 실현된다. 복수의 메모리 셀의 구현이 더 높은 집적도와 고속의 쓰기 읽기를 위하여 구현된다. 실시간 인식을 위하여 본 연구에서 사용된 함수는 이상적이며 메커니즘의 시뮬레이션을 위하여 MOSIS의 $1.2{\mu}$ 더블폴리 CMOS 공정 파라미터를 사용하였다.

Purpose: The present study offers merger and acquisition (M&A) strategy based on prior studies to assist the organizational practitioners in two companies' cultures. In the analysis, a M&A plan to guide the evolving principles was created by present authors using change management model. Research design, data, and methodology: The successful M&A integration is setting goals, reconfiguring the cultural systems to align them with business goals. The employees must be involved, particularly with organizational change. Both companies also ought to undertake employee training following the resolving of worries and needs of employees. Finally, restructuring can include the moving of employees from areas where they may be struggling. Result: Discussing and trying to come to an agreement over which mode of acculturation would be most suitable in that particular state is the main focus. Practitioners of both Company A and Company B might find it much simpler to continue their focus and dynamism in the process of cultural integration. Conclusions: We believe that our approach adds an insight in the M&A literature. Managers at all levels of both organizations must take part in the process of M&A for both organizational cultures to come in sync and for change to take place.

본 논문에서는 PI형태의 속도제어기를 장착한 고성능 유도전동기의 조건부 적분형 자동 튜닝 anti-windup 기법을 제안한다. 제안된 방법에서는 전동기 운전 조건에 대한 사전 정보 없이도 전동기 토오크 지령의 주파수 해석에 의해서 적분기 온/오프 시점이 결정된다. 따라서, 사용자는 anti-windup 동작을 위한 별도의 제어 상수를 설정하지 않아도 된다. 또한, 동작 조건이 변동하여도 과도 상태의 속도는 항상 최소한의 오버슈우트와 점착시간을 가지도록 동작한다. 본 기법은 속도 및 토오크 응답의 오버슈우트를 허용하지 않는 유도전동기 고성능 응용 분야에 유용하게 적용 될 수 있으며, 기본 개념은 화학 공정이나 산업용 로봇과 같은 일반 산업 응용 분야에도 확대 적용 가능하다.

Sample independent t-test is applied to compare the financial performance of outsourcing and vertically integrated firms. Results - Based on the investigation of 10 years' data of financial ratio, the results of the study show that there is significant difference between outsourcing and vertical integration strategy on return on assets, return on equity while insignificant difference has found with profit margin. Conclusions - The findings of the current study indicates that there is significant difference between the financial performance of outsourcing and vertically integrated firms in terms of return on asset, return on equity and insignificant difference in terms of profit margin.

The flow of the $4^{th}$ Industrial Revolution calls for the innovation of the traditional business models of the manufacturers. Servitization is a corporate strategy to respond to changes in the business environment. These days, the value that the market demands can be created on the basis of the product-service integration. Thus the manufacturers must pursue the fundamental innovation of the current strategy and business models. It is necessary to create common values with customers through providing product-service integrated offerings beyond the development, production, and delivery. The purpose of this study is to develop the evaluation indicators for selecting suppliers when the manufacturer who offers the value of product-service integration needs to obtain the resources from outside. The case company in this study is the manufacture firm conducting the retail IoT business as a new business. The Delphi method is used to develop the evaluation indicators for selecting suppliers. This study suggests the academic implications providing the perspective of Servitizaiton by using Delphi method, and the practical implications applying the creating value method of Servitization by collecting the opinions from both value providers and value consumers in the process of developing the evaluation indicators.

Korea currently provides long-term care benefits for the elderly with poor functionality, but most of the service providers are private businesses. This is the time when quality management of care services is required, which is just around the corner of the super-aged era. In this study, we would like to look at the case in which 'A company', which operates a long-term care institution, attempted to make voluntary changes ahead of social demands. The company tried to transform the social needs of quality management by judging them as opportunities, not threats, and establishing an integrated database of centers. First, the company processed data and built a cloud-based database system. Second, the company automatically linked data from existing systems for the efficiency of data utilization. Third, the company pursued visualization for the convenience of data utilization. This allowed the company to make data-driven strategic decisions internally. This is expected to increase sales as it will soon lead to securing new customers and pioneering new markets. It is also significant in that it can provide best practices for the long-term care industry.

This paper describes a progressive test and evaluation strategy for verification of Korean Fighter eXperimental (KF-X) AESA(Active Electronically Scanned Array) radar development. Three progressive stages of development test and evaluation were officially performed from simulated test conditions to actual operating conditions according to standards: radar function/performance and avionics integration. KF-X AESA radar development is repeatedly verified by progressive stages consisting of five tests: Roof-lab ground test, System Integration Laboratory(SIL) ground test, Flying Test Bed(FTB) test, KF-X ground test, and KF-X flight test. As a result, the risk factor decreases as stages and tests progress. Therefore, development test and evaluation of KF-X AESA radar are successfully performed at low development risk.

본 연구는 기업의 업무프로세스 상에서의 정보기술 경쟁우위가 공급사슬통합에 어떻게 영향을 미치는지를 분석하고, 업종별 비교분석을 통해 기업들의 효과적인 공급사슬통합을 위한 정보기술 경쟁우위달성방안을 제시하는데 목적이 있다. 연구가설은 이론적 배경을 기초로 하여 크게 두 가지로 구성하였다. 첫 번째 연구가설은 정보기술 경쟁우위가 공급사슬에 미치는 영향에 대한 가설이고, 두 번째 가설은 정보기술 경쟁우위가 공급사슬통합에 미치는 영향이 업종별로 차이가 있다는 가설이다. 기업의 경쟁력 확보를 위한 정보기술 경쟁우위 달성을 위해서는 IT인프라의 확보가 선행되어야 할 것이다. IT인프라에 대한 지속적인 관심과 투자를 바탕으로 정보기술의 도입, 통합, 활용 등 정보기술 경쟁우위 그 자체로 기업성과 향상에 직접적인 영향을 미칠 수 있지만, 정보통합, 조직통합, 전략통합과 같은 공급사슬통합 수준향상에 전략적으로 활용되어야 한다. 정보기술 경쟁우위 확보를 통해 공급사슬 통합이 효과적으로 이루어지면, 기업성과 향상을 도모할 수 있을 것이고 이를 바탕으로 기업의 경쟁우위를 창출하게 될 것이다. 기업의 정보기술 경쟁우위가 공급사슬통합에 미치는 영향을 분석하고, 각 업종 유형별 특징에 따라 어떠한 차이가 있는지를 비교분석하여, 효과적인 공급사슬통합을 위한 정보기술 경쟁우위와 공급사슬통합방안을 제시할 수 있을 것이다.

Human balance is maintained through a complex process involving sensory detection of body motions, integration of sensorimotor information within the central nervous system, and execution of appropriate musculoskeletal responses. The basic task of balance is to position the body center of gravity (COG) over some portion of the support base. When the COG extends beyond the base of support, the person has exceeded the limits of stability (LOS). At this point, a step or stumble is required to prevent a fall. Automatic postural responses operate to keep the COG over the base of support. They are a set of functionally organized, long-loop responses that act to keep the body in a state of equilibrium. There are four commonly identified automatic postural responses, or strategies. These are ankle strategy, hip strategy, suspensory (knee) strategy, and stepping strategy. Thus, the purpose of this study was to evaluate the LOS using various knee strategies. Forty subjects participated in this study. The subjects were comprised of 20 males and 20 females who were without neurologic, orthopaedic or balance performance impairments. The LOS was measured with a Balance Performance Monitor (BPM) Dataprint Software Version 5.3. The results of this study were as follows: 1) Knee joint angle which is to increase stability of standing balance with using knee strategy was at mid-range. 2) There were statistically significant differences in anteroposterior LOSs according to the knee strategy. 3) There were no statistically significant differences in mediolateral LOSs according to the knee strategy. 4) There were statistically significant differences of anteroposterior LOSs with using knee strategy according to gender. 5) There were no statistically significant differences in mediolateral LOSs with using knee strategy according to gender.
