China’s Asset Bubble: Truth or Imagination

김연준 한국국제금융학회 2011 국제금융연구 Vol.1 No.2

This paper investigates whether there is an asset bubble in China. This paper compares asset bubbles in the US and Japan with asset bubble in China using a historical data. We expect that Chinese government has an ability, in some measure, to control the spread of bubble in asset market. And, Chinese government has an ability to control inflation that may occur with asset bubble. On the other hand, Chinese government elastically and loosely cut liquidity, retrench, and pump-priming to secure domestic growth. After reviewing all the analysis regarding Chinese asset market and ‘domestic and foreign’ environment, we conclude that there is a low possibility in fluctuating asset prices in the short-run in China. However, there are some other risk factors that may affect to the other countries and these risk factors are different from the previous periods in China.

김연준,김은수,김아연,이재은 (사)위기관리이론과실천 2023 Crisisonomy Vol.19 No.8

This study aims to analyze the perceptions of climate crisis risk, roles of actors, green living practices, carbon neutrality policies, and policy outcomes to set policy directions for achieving carbon neutrality to overcome the climate crisis. The main findings of this analysis are as follows. First, there are gender differences in risk perceptions between men and women regarding the likelihood of survival threats from the climate crisis. Second, there are differences in the roles of different actors in carbon neutrality policy behavior. Third, respondents are currently uncomfortable with the idea of going carbon neutral, and policy effectiveness is low. Fourth, respondents are willing to accept the inconvenience of strengthening laws and regulations to realize carbon neutrality. Fifth, the most common way to learn about pro-neutrality policies is through mass media. Sixth, purchasing recycled products and recycling consumption were the most preferred actions. Seventh, the lack of information on the scope and timing of climate change impacts was the most serious problem with the carbon neutrality policy. The most preferred policies were: recognizing the seriousness of the climate crisis and environmental education, supporting social systems, and providing incentives and points.

김연준 한국외국어대학교(글로벌캠퍼스) 동유럽발칸연구소 2019 동유럽발칸연구 Vol.43 No.3

Romania joined the EU in 2007 and achieved its goal of sustainable economic development. Romania has been experiencing a steady economic recovery since 2008 when it suffered from economic difficulties from the U.S. originated global financial crisis. This study conducts an empirical analysis to test whether Romania's economic growth has led to an increase in employment. Specifically, the Granger-causality test is conducted to demonstrate and analyze the relationship between economic growth and employment in Romania. This study also divides research period into three periods to conduct structural analysis: the whole period, before Romania joined the EU, and after Romania joined the EU. Results of the empirical test show that increase in GDP affects increase in employment in case of Romania with and without structural analysis. Romania has shown that continuous economic growth has had a positive effect on job creation.

It has been fifteen years since military science was introduced into private and public universities since 2004. The department focuses on the improvements of the South Korean Army quality based on the Korean Army's traits including: an increase of power in the armed force and operations through research, development, and the expansion of a cooperation between the public (civilians) and military. Approximately, four hundred students from various universities in the military science department graduate in order to become an officer. The fourth industrial revolution causes structural transformation to our lives. Through the use of Artificial Intelligence (AI,) war and the military as a whole will be altered significantly particularly with regard to efficiency. Nevertheless, it is important for us to train officers in creative ways so that they can deal with situations where machines will be unable to handle situations. Considering this change in our lives, it is necessary for the military science departments to change the way to teach and train their students. In order to accomplish this goal, we need to introduce a method called "Flipped Learning" and during the process all the members need to participate and communicate in an interactive way. By doing this, the military science departments will play an important role by improving human resource in terms of military and national security.

Design of an ASK RF Transceiver for ETCs with Hybrid ASK Modulator and Ultra Low Power Wake-Up Receiver

김연준,정재형,오태섭,김재빈,조종완,이강윤 한국과학기술원 반도체설계교육센터 2023 IDEC Journal of Integrated Circuits and Systems Vol.9 No.1

This article proposes a transceiver structure of RF with modulation by Amplitude-Shift-Keying (ASK) for ETCs (Electrical Toll Collection system). To meet Korean and Chinese standards, the modulator of TX supply to propose a method of hybrid approach. The Korean model is 1024 kbps, the Chinese OBU is 512 kbps and the road-side-unit (RSU) has a data transfer speed of TX of 256 kbps. The hybrid structure has advantages over the analog type in terms of area, energy consumption, process, voltage, variation of PVT. The China ETC way is working with battery and should reduce the energy consumption. The transceiver of main RF is switched off until the Wake-up receiver (WuR) receives the Wake-up signal of the RSU, for what most of the time that the Wake-up receiver is working is busy, so it is essential to minimize power consumption of the WuRx. In WuRx, the detector involving the envelop detection of the Wakeup signal using the current feature of the MOSFET which operates in the region of the sub-threshold, which allows the operation with ultra-low power. The digital filters are used to improve the reliability of the alarm signal. In these ways, the Wakeup block's total power consumption is 3.6uA. ETC operates when On-Board-Unit (OBU)'s Road-Side Unit (RSU) at high speed. Therefore, the automatic control of gain of RX is not supported in this work. In the common RX, there is an automatic controller of gain to avoid saturation of Rx power. But even ETC cannot adjust the gain, for what it takes a performance of the receiver with an extended Rx dynamic range when used as with a steady gain. To comply with the highest P1dB specification and the wide dynamic range of Rx, the receiver proposes a structure for demodulating the ASK signal with LNA, mixer and Received Signal Strength Indicator (RSSI). The Rx dynamic range is 70dB. The transceiver is implemented in a 1P8M CMOS process of 130 nm, with an active area of 3.5mm × 3.5 mm, including the ESD protection pads.

This study analyzed the effect of designation and creation of innovative cities on per capita local taxes (local taxes by tax category, total local tax, and independent revenue) of local governments through the difference-in-difference method. The main results are as follows. First, the creation of an innovative city increased the total amount of city・county, and district’s local taxes per capita by 13.4% and 14.5%, respectively. Second, local tax items, which increased the most due to the creation of innovative cities, were acquisition tax per capita for city・county, and per capita income tax for the district. Third, the creation of an innovative city increased city・county, and district’s independent revenue per capita by 4.9% and 14.1%, respectively. These results suggest that the increase in the financial power of local governments due to the creation of innovative cities varies depending on the type of local governments(city・county, district). 본 연구는 이중차분법을 통해 혁신도시 지정 및 조성이 시・군 자치단체 및 자치구의 1인당 지방세입(세목별 지방세, 지방세 총액, 자체수입)에 미친 영향을 분석하였다. 주요 분석결과는 다음과 같다. 첫째, 혁신도시 조성은 시・군 자치단체와 자치구의 1인당 지방세 총액을 각각 13.4%, 14.5% 증가시켰다. 둘째, 혁신도시 조성으로 인해 가장 크게 증가한 지방세목은 시・군 자치단체의 경우 1인당 취득과세로 나타났으며 자치구의 경우 1인당 소득과세로 나타났다. 셋째, 혁신도시 조성은 시・군 자치단체와 자치구의 1인당 자체수입을 각각 4.9%, 14.1% 증가시켰다. 이러한 분석결과는 혁신도시 조성으로 인한 지방자치단체의 재정력 증가가 자치단체 유형(시・군, 자치구)에 따라 상이함을 시사한다.
