Purpose: This study examined how interpersonal relationship abilities in the elderly affected anger control abilities, as well as the mediating effects of generativity in the relationships between interpersonal relationships, anger control abilities, and self-integration. Research design, data and methodology: The study consisted of randomly selected 300 elderly people currently residing in welfare centers for the elderly, senior citizens colleges, social welfare facilities and other centers in the Seoul or Gyeonggi area. SPSS 23.0 was utilized for this study. Results: Through this research, the effect of interpersonal relationships on anger control ability and self-integration was observed. Not only that, the effects of interpersonal relationship abilities on anger control and self-integration and the mediating role of generativity, was also closely examined. Conclusion: Anger control ability was found to have a direct positive effect on interpersonal relationship abilities. Anger control ability had a direct and positively correlated effect on self-integration. Additionally, ability to control anger was found to have a positive effect on generativity, and generativity was found to have a positive effect on interpersonal relationship ability, but it was not statistically significant. Anger control ability had a positive effect on generativity, and generativity had a positive effect on self-integration.

본 연구에서는 온도가 보상된 압력을 제연구역의 기준압력으로 설정하기 위한 공학적인 메커니즘과 보상방법을 정립하였고, 통합 제연시스템의 컨트롤러의 개발을 위한 프로세스, 알고리즘 확립과 엔지니어링 데이터의 구축으로 신뢰성이 확보된 통합 제연시스템의 컨트롤러를 개발하였다. 컨트롤러를 개발함으로서 비제연구역의 압력측정을 위해서 별도로 설치되는 압력측정관을 생략할 수 있어 제작단가와 설치비용 및 작업공수를 줄일 수 있고, 층별 제연구역의 차압측정을 위한 비제연구역의 압력측정포트를 시스템에 일체화함으로서 차압의 정밀도를 향상시킬 수 있다. 기존의 개별제어 방식에서 통합 제연시스템의 컨트롤러로부터 중앙집중식 통합관리를 함으로서 보다 정확하고 신뢰성 있는 차압을 얻을 수 있으며, 제연시스템에 유연성을 부과시킬 수 있을 것으로 본다. 또한 통합 제연시스템의 기틀을 마련하고 제연의 유연성을 주며 방재성능을 향상시킬 것으로 본다.

This study empirically investigated the relationships among inter-organizational cost management (IOCM), cooperation with suppliers, information exchange between partners, inter-organizational learning, control integration, and the supply-chain performance of a firm. The results showed that the adoption of IOCM positively affects the collaboration between buyers and suppliers, which also leads to the increased information flow between them. According to the results of this study, it was found that inter-organizational information flow causes inter-organizational learning, and this learning contributes to the improved supply-chain performance. In this study, the positive effects of the cooperation with suppliers through IOCM on the control integration in supply-chains were not empirically confirmed. However, the impact of IOCM on control integration was significant and positive. Finally, the fact that the enhanced control integration can improve the supply-chain performance of a firm was empirically demonstrated.

The INS/GPS integration system is designed by employing an adaptive filter that can estimate the measurement noise variance using the residual of the filter. To verify the efficiency of the proposed loosely-coupled INS/GPS integration system, simulation is performed by assuming that GPS information has large position errors. Simulation results show that the proposed integration system with the adaptive filter is more effective in estimating the position and attitude errors than those with the Extended Kalman Filter.

In land navigation applications, two kinds of GPS/DR integration schemes are commonly used; the loosely-coupled integration scheme and the tightly-coupled one. The loosely-coupled integration filter has a simple structure and is easy to implement. When the number of visible satellites is insufficient, however, it cannot calibrate the errors of the DR sensors. On the contrary the tigthly-coupled integration filter can sup-press the growth of the error in the DR output even when the visibility is poor. However, it has larger com-putation load due to the state dimension and is inconsistent because of the variation in the measurement dimension. This paper presents a GPS/DR integration scheme with dual integration mode. During when the number of visible satellites is sufficient, the proposed scheme operates in a loosely-coupled integration mode. When the visibility becomes poor, it is switched into a tightly-coupled integration mode. Consequently, the pro-posed scheme can calibrate the DR sensors even when the visibility is poor. In addition, its computation time remains constant even if the number of visible satellites increases. Field experiment results show that the performance of the proposed integration method is almost similar to that of the tightly-coupled one.

This paper describes limitations and solutions of the existing processor-monitoring concept for a military supersonics aircraft Flight Control Computer (FLCC) equipped with modern architecture processor to perform the system integration test. Safecritical FLCC integration test, which requires automatic test for thousands of test cases and real-time input/output test condition generation, depends on the processor-monitoring device called Processor Interface (PI). The PI, which relies upon on the FLCC processor's external address and data-bus data, has some limitations due to multi-fetching capability of the modern sophisticated military processors, like C6000's VLIW (Very-Long Instruction Word) architecture and PowerPC's Superscalar architecture. Several techniques for limitations were developed and proper monitoring approach was presented for modem processor-adopted FLCC system integration test.

Vertical velocity is critical in many areas, such as the control of unmanned aerial vehicles, fall detection, and virtual reality. Conventionally, the integration of GPS (Global Positioning System) with an IMU (Inertial Measurement Unit) was popular for the estimation of vertical components. However, GPS cannot work well indoors and, more importantly, has low accuracy in the vertical direction. In order to overcome these issues, IMU-barometer integration has been suggested instead of IMU-GPS integration. This paper proposes a new complementary filter for the estimation of vertical velocity based on IMU-barometer integration. The proposed complementary filter is designed to minimize drift error in the estimated velocity by adding PID control in addition to a zero velocity update technique.
