오늘날 부동산 특히 주택과 관련한 많은 정부정책이 발표됨에 따라 주택시장에서의 가격에 대한 관심이 매우 높아졌다. 이에 본 연구에서는 소득의 불안정성과 부동산가격변동에 대한 심리상태와 부동산보유비중의 조정의향 간의 관련성을 분석하여 정부정책의 실효가능성을 살펴보고자 한다. 먼저 선행연구 검토를 통해 주요 변수를 추출하고 설문조사를 통해 자료를 수집하여 경로분석을 실시하였다. 분석결과 현재의 소득의 불안정성은 부동산가격변동에 대한 태도에 음(-)의 영향을, 부동산보유비율조정의향에는 양(+)의 영향을 미쳤으나, 부동산가격변동에 대한 태도가 부동산보유비율조정의향에는 통계적으로 유의한 영향을 미치지 않았다. 이에 연령대와 부양가족 수를 각각 2분하여 집단간 차이분석을 실시하였으며, 분석결과 부동산보유비중 의사결정은 연령대가 높은집단과 부양가족수가 많은집단에서 소득불안정성과 부동산가격변화에 대한 태도에 의해 영향을 받아 집단 간 차이를 보였다. 본 분석 결과는 정부의 부동산 정책 수립방향 설정과 각 가계의 부동산 관련 의사결정에 기초자료로 활용하는데 도움이 될 것이다. 한편 본 연구는 횡단면분석만을 실시한 한계점을 갖고 있으며 향후에는 시계열적 변화와 지역간 인식의 차이 등을 분석하고자 한다.

The hydraulic loading system real-time simulator using a PC and I/O interface board is developed to simulate the dynamic characteristics of hydraulic loading system in real time. The simulator receives the digital on-off control signals generated by the operator through the D/I channels, updates the state and output variables of the hydraulic loading system responding to the input signals and draw the moving pictuters of the lift cylinder, lift arm and loading box on the PC monitor in real time. Also, the operator can observe the displacement and pressure of cylinder, the rotatinal angle, reaction force, and safety factors of lift arm representing the operation of hydraulic loading system through the PC monitor in real time. The real-time simulator can be a very useful tool to design industrial dynamic systems and feel the goodness of the system operation since the operator can observe the moving pictures of the operating system in real time as he operates the real time simulator.

As the complexity of the power system becomes higher, tests of the new devices, such as exciter and PCS(Power Conversion System) of the distributed generation sources, in the real operating condition are more important. However tests of the unverified devices in the real power system may cause hazardous malfunction of the system. In order to avoid this problem, power devices may be tested with the real-time simulators instead of the real power system. This paper presents an real-time multi machine power system simulator using PCs(Personal Computer) and Fast Ethernet. Developed real-time simulator performs the electro-mechanical dynamic simulation of multi-machine power system by the network distributed computing technique. Because the simulator consists of usual PCs and Fast Ethernet, it is possible to make up a simulation system very cheaper than the conventional real-time simulator which consists of dedicated expensive hardware devices. The performance of the developed simulator is tested and verified with the scaled model excitation system. The test which adjust the control parameters of the exciter is performed with the well-known New England 10 generator 39 bus sample power system.

This research aims to investigate the determinants of real effective exchange rate in emerging ASEAN countries, including Indonesia, Malaysia, Philippines, Thailand, and Vietnam. The research was conducted by using quarterly time series data set from 1980Q1 to 2020Q3. Cointegration and the error correction model (ECM) methods were applied to test the long run and short run relationship of the real effective exchange rate and its determinants. The results indicate that the ratio of foreign direct investment to GDP and the government spending have significantly positive impact on real effective exchange rate in the Emerging ASEAN countries. The trade opening had influencing real effective exchange rate in most the Emerging ASEAN countries, except Vietnam. In addition, the international reserve (INR) had significant long-run impacts variables on real effective exchange rate in Malaysia, Thailand and Vietnam. In the short run equilibrium, the error collection term suggest that Indonesia and Malaysia are the fastest speed adjustment to equilibrium. In addition, the term of trade influence the real effective exchange rate in Indonesia, Malaysia, and the Philippines but it is not in Thailand and Vietnam. However, FDI is a major factor of the real effective exchange rate in Vietnam, but not for other countries.

The real time scheduling is a key research area in high performance computing and has been a source of challenging problems. A periodic task is an infinite sequence of task instance where each job of a task comes in a regular period. The RMS (Rate Monotonic Scheduling) algorithm has the advantage of a strong theoretical foundation and holds out the promise of reducing the need for exhaustive testing of the scheduling. Many real-time systems built in the past based their scheduling on the Cyclic Executive Model because it produces predictable schedules which facilitate exhaustive testing. In this work we propose hybrid scheduling method which combines features of both of these scheduling algorithms. The original rate monotonic scheduling algorithm didn't consider the uniform sampling tasks in the real time systems. We have enumerated some issues when the RMS is applied to our hybrid scheduling method. We found the scheduling bound for the hard real-time systems which include the uniform sampling tasks. The suggested hybrid scheduling algorithm turns out to have some advantages from the point of view of the real time system designer, and is particularly useful in the context of large critical systems. Our algorithm can be useful for real time system designer who must guarantee the hard real time tasks.

배경: PANA RealTyper HPV kit (PANAGENE, Korea; PANA RealTyper)는 multiplex real-time PCR과 melting curve analysis를 이용하여 human papillomavirus (HPV)의 유전자형을 검출한다. 본 연구에서는 PANA Real Typer와 AdvanSure HPV GenoBlot assay (LG Life Sciences, Korea; AdvanSure assay)를 비교하였다. 방법: 자궁경부암 검진을 받은 환자에서 채취한 검체를 60개 수집하였다. AdvanSure assay와 PANA RealTyper는 고위험군 HPV 20종을 검출할 수 있다. 저위험군 HPV의 경우 AdvanSure assay는 15종을, PANA RealTyper는 2종의 유전자형을 구별할 수 있고 18종의 유전자형을 검출할 수 있다. 결과: 총 60개 중 40개 검체에서 54개의 고위험군 유전자형이 검출되었으며 18개 검체에서 20개의 저위험군 유전자형이 검출되었다. 고위험군에서 두 방법 간 일치율은 94.4-100%였다. PANA Real Typer에서만 양성으로 검출된 9개 유전자형 중 7개(HPV 16 (n=1), 39 (n=1), 52 (n=1), 58 (n=2), 68 (n=2))은 진양성으로 판별되었다. AdvanSure assay에서만 양성으로 나온 4개 유전자형 중 3개는 HPV 59였다. 저위험군에서 AdvanSure assay에서 검출된 19개 유전자형 중 HPV 6 2개, HPV 11 1개였다. HPV 6 중 한 개는 PANA RealTyper에서만 양성이었다. 결론: PANA RealTyper는 AdvanSure assay와 동등한 검출력을 보였으며, 임상 검사실에서 HPV 유전자형 검사에 유용하게 쓰일 수 있을 것으로 생각한다.

Real-time prediction of Web service of quality (QoS) provides more convenience for web services in cloud environment, but real-time QoS prediction faces severe challenges, especially under the cold-start situation. Existing literatures of real-time QoS predicting ignore that the QoS of a user/service is related to the QoS of other users/services. For example, users/services belonging to the same group of category will have similar QoS values. All of the methods ignore the group relationship because of the complexity of the model. Based on this, we propose a real-time Matrix Factorization based Clustering model (MFC), which uses category information as a new regularization term of the loss function. Specifically, in order to meet the real-time characteristic of the real-time prediction model, and to minimize the complexity of the model, we first map the QoS values of a large number of users/services to a lower-dimensional space by the PCA method, and then use the K-means algorithm calculates user/service category information, and use the average result to obtain a stable final clustering result. Extensive experiments on real-word datasets demonstrate that MFC outperforms other state-of-the-art prediction algorithms.

This paper describes how to use Profibus networks to support real-time industrial communications, that is, how to ensure the transmission of real-time messages within a maximum bound time. Profibus is based on a simplified timed token protocol, which is a well-proved solution for the real-time communication systems. However, Profibus differs from the timed token protocol, thus the usual timed token protocol has to be modified in order to be applied in Profibus. In fact, the real-time solutions for networks based on the timed token protocol rely on the possibility of allocating specific bandwidth for the real-time traffic. This means that a minimum amount of time to transmit the real-time messages is always guaranteed whenever each token is arrived. In other words, with the Profibus protocol, at least, one real-time message should be transmitted per every token visit in the worst case. It is required to control medium access properly to satisfy the message deadlines. In this paper, we have presented how to obtain the optimal network parameter for the Profibus protocol. The selected network parameter is valid regardless of the behavior of asynchronous messages.
