건물에 복수개의 엘리베이터가 설치되어질 때 각 엘리베이터의 불필요한 이동으로 인한 에너지 손실을 줄이고 승객의 요구에 따라 적절한 층에 카를 할당하는 제어를 엘리베이터 군관리제어라고 한다. 그러나 장애인용 엘리베이터는 3대 이상이 군관리제어가 될 경우 어느 호기가 호출될지를 예측할 수 없으므로 장애인들의 편의를 보장하기 위하여 국내의 관련 기준에 따라 군관리방식이 제한되며 적용될 수 없다. 본 논문에서는 개선방안으로서 일반 엘리베이터와 장애인용 엘리베이터를 통합한 군관리제어 방식을 제안하였으며 기존의 분리된 운영방식과 비교하여 호출 후 대기시간 16.9 % 감소의 효율성을 검증해 보았고, 장애인용 엘리베이터는 선택적으로 독립운행이 되도록 함으로써 승강기 검사기준과 보건복지부의 유권해석 모두에 위배되지 않고 효율을 극대화할 수 있는 개선된 통합 군관리제어 시스템임을 컴퓨터 시뮬레이션을 통해 입증하였다.

The integrated global position system (GPS) and inertial navigation system (INS) has been considered as a cost-effective way of providing an accurate and reliable navigation system for civil and military system. Even the integration of a navigation sensor as a supporting device requires the development of non-traditional approaches and algorithms. The objective of this paper is to assess the feasibility of integrated with GPS and INS information, to provide the navigation capability for long term accuracy of the integrated system. Advanced algorithms are used to integrate the GPS and INS sensor data. That is fuzzy inference system based Weighted Extended Kalman Filter(FWEKF) algorithm INS signal corrections to provided an accurate navigation system of the integrated GPS and INS. Repeatedly, these include INS error, calculated platform corrections using GPS outputs, velocity corrections, position correction and error model estimation for prediction. Therefore, the paper introduces the newly developed technology which is aimed at achieving high accuracy results with integrated system. Finally, in this paper are given the results of simulation tests of the integrated system and the results show very good performance

In this paper, we design and implement the monolithic power factor correction IC for system power modules using a high voltage(50V) CMOS process. The power factor correction IC is designed for power applications, such as refrigerator, air-conditioner, etc. It includes low voltage logic, 5V regulator, analog control circuit, high-voltage high current output drivers, and several protection circuits. And also, the designed IC has standby detection function which detects the output power of the converter stage and generates system down signal when load device is under the standby condition. The simulation and experimental results show that the designed IC acts properly as power factor correction IC with efficient protective functions.

As the public interest in environmental issues increased, the "Act On The Integrated Control Of Pollutant-Discharging Facility" was enacted. Through the integrated environmental pollution prevention act in which 19 industries with large environmental impacts are sequentially applied, pollutants can be managed in a medium-integrated manner and integrated permission of the business unit is possible and BAT can be applied to enable a scientific and proactive environmental management system. In order to facilitate the implementation of integrated environmental pollution prevention act with these advantages, the BAT BREF should be published, modified and revised every 5 years considering the level of scientific development. This study reviewed the issues to be considered in applying BAT and the types of BAT and focused on presenting improvements and development direction when revising and supplementing the standards in the future based on these contents. For this purpose, when revising the standards, it will be necessary to reflect on the domestic situation, to expand the TWG(Technical Working Group) of small-scale workplace experts, and to exchange opinions with business places that have similar processes for each waste type through a systematic total inspection. In addition to these methods, by establishing a resident participation system through information disclosure, it is expected to be used as a guideline for environmental management of business places not subject to integrated permission of less than 3 types as well as those subject to integrated permission.

The objective of this study is intended to propose plans for reforming environmental impact assessment(EIA) systems by reviewing the current legal systems of EIA related laws and their implementation status in Korea, and by comparing the Korean situation to EIA systems in several foreign countries. This study tried to integrate all EIA related systems scattered over several laws into one comprehensive EIA law, and also to develop legal procedures necessary to accomplish the legislative purpose of the integrated EIA law. Therefore, I propose four reforms (1) All EIA systems should be integrated into one comprehensive EIA act. (2) Administrative plans and policies, though environmentally harmful, which are not currently subject to any prior consultation system, should be covered by the prior consultation system. (3) A screening or scoping should be adopted. (4) Widen civil participation should be encouraged and the administrative control enforcement and introduction of group litigation or citizen suits would be considered.

The emergence of new technologies and their implementation by different manufacturers of electronic devices are experiencing an ascending trend. Most of the time, these protocols are expected to reach a certain degree of maturity, and electronic equipment manufacturers use simplified communication standards and interfaces that have already reached maturity in terms of their development such as ModBUS, KNX or CAN. This paper proposes an IoT solution of the Smart Home type based on an Analysis and Prediction System. A data acquisition component was implemented and there was defined an algorithm for the analysis and prediction of actions based on the values collected from the data update component and the data logger records.

본 연구는 간호대학생을 대상으로 개발한 문제중심학습 연계 시뮬레이션교육을 적용한 후 학생의 시스템 사고능력, 학습몰입, 문제해결 적극성 및 투약간호 수행능력에 미치는 효과를 검증한 비동등성 대조군 전후설계의 유사실험연구이다. 연구대상은 전북과 경인지역에 소재한 간호대학생으로 실험군 37명, 대조군 41명이었고, 실험군에게는 문제중심학습 연계 시뮬레이션 교육프로그램, 대조군에게는 시뮬레이션 교육프로그램을 적용하였다. 자료수집은 프로그램을 적용하기 전과 후에 측정하였고, SPSS WIN Version 22.0 프로그램을 이용하여 분석하였다. 연구 결과, 실험군이 대조군에 비해 시스템 사고능력(t=2.14, p=.036), 문제해결 적극성(t=2.07, p=.042) 및 투약간호수행능력(t=5.26, p=<.001)은 유의하게 향상되었으나 학습몰입은 통계적으로 유의하지 않았다. 따라서 간호대학생의 임상상황에서의 적응을 위하여 교수자들은 문제중심학습 연계 시뮬레이션 교육을 교과과정에 적용하는 것을 고려할 필요가 있다.

Objective : The immune system is a complex of systems, all of which work together to clear infection from the body. In Korea, red ginsenghas been one of the herbs most widely used to enhance the immune system for thousand of years. More recently, red ginseng has been reported to have many positive effects on the immune system. The purpose of this study was evaluate the effects of Korean red ginseng and Chinese red ginseng on IgG, IgM, and IgA, using immunoglobulin productivity assay. Methods : Male SD rats were separated into 3 groups. We administered Korean red ginseng (KRG) to one group and Chinese red ginseng (CRG) to another, with normal saline for the Control group consecutively and orally for 3 months. The dose of red ginseng was 500mg per day, as a powder with soluble water. Immunoglobulin levels from spleen cell were estimated by ELISA kit. Results : In immunoglobulin productivity assay (cell), the IgG level of the KRG group significantly increased but there was no significant difference in the IgG of the CRG group. The IgM level of the KRG group significantly increased stimulated with PWM. When it was unstimulated, the level of IgM in KRG and CRG increased together. The IgA level of the KRG group significantly increased when it was stimulated with PWM and unstimulated. Conclusion : According to the above results, oral administration of red ginseng for 3 months is considered useful for immunomodulatory effect, and Korean red ginseng may be superior to Chinese red ginseng in that effect.

Intelligent Control is an extended paradigm that subsumes both control and AI paradigms, each of which is limited by its own abstractions. Autonomy, as a design goal, offers an arena where both control and AI paradigms must be applied -and a challenge to the viability of both as independent entities. We discuss hierarchical event-based control architectures in which AI and Control paradigms can be integrated within a model-based approach. In a niodel-based system, knowledge is encapsulated in the form of models at the various layers to support the predefined system objectives. Concepts are illustrated with a robotmanaged space-borne chemical laboratory.
