News and Business Cycles for Korea
허준영 한국계량경제학회 2015 계량경제학보 Vol.26 No.4
How important is ``news'' about not-yet-realized economic fundamentals in macroeconomic fluctuations for Korea? To address this question, this paper estimates a small open economy real business cycle model embedded with the anticipated components of exogenous shocks. Three main findings emerge based on an analysis of Korean data ranged from 1960:Q2 to 2014:Q4. First, a substantial fraction of the variability of output, consumption, and investment is accounted for by unanticipated shocks. Anticipated shocks play a critical role in causing fluctuations in government spending and trade balance, but their business cycle implications are weak. Second, the contribution of anticipated shocks to output and consumption fluctuations increases from the late 1980s to the onset of the Asian currency crisis of the late 1990s. Anticipated shocks account for a dominant fraction of investment variability during the recession period associated with the Asian currency crisis, and of trade balance movements in the post-crisis period. Finally, the financial friction mechanism, in which the country's interest rate spread is dependent upon the level of sovereign debt, has substantial implications for the output and investment dynamics in the model.

2종 LiBr - H<sub>2</sub>O 흡수식 열펌프의 시뮬레이션
허준영,최영돈,Huh, J.Y.,Choi, Y.D. 대한설비공학회 1989 설비공학 논문집 Vol.1 No.2
The second kind LiBr-$H_2O$ absorption heat pump system was simulated and the performances of it were predicted. The elements of heat pump system, evaporator, absorber and generator were analysed by solving the energy balance equations and concentration equations which describe the reactions between working fluids. The results show that the temperature gain of absorber is affected considerably by the operating conditions of heat pump system, on the other hand, COP is little affected by them.

허준영 한독사회과학회 2017 한독사회과학논총 Vol.27 No.2
본 연구의 목적은 독일 통일 후 베를린으로의 수도이전에 따른 연방행정기관의 분할 배경 및 현황을 살펴보고 관련된 행정적인 문제점과 독일 정부의 대응을 심층적으로 분석하여 현재 세종시 이전에 따른 행정비효율 문제에 대한 해법을 벤치마킹하고자 함이다. 연구결과 독일은 구 수도인 본(Bonn)에 대한 보상차원에서 연방행정기관의 분할이 결정되어 1청사, 2청사 개념으로 수평분할의 형태를 띠고 있으며 이로 인한 행정문제를 IT 연결망과 영상회의실을 이용한 도구적 근접성 제고 측면에서 접근하여 해결하였다. 한편 행정부 위주의 노력뿐만 아니라 입법부에서도 분할로 인해 발생하는 출장비 외에 사무실 임대 등 실질적인 비용들로 산정하면서 행정부에 분할비용보고서 제출의무를 부과하는 등 적극적인 감독권을 행사하면서도 한편으로는 사전 의회일정 고지 및 수행인원 제한 등 행정부와 협력적으로 연방의회사무 처리를 수행하는 등 조직적 근접성 측면에서의 노력도 확인할 수 있었다. 이러한 시사점을 바탕으로 한국 행정에 주는 교훈을 살펴본다. The purpose of this study is to investigate the background and status of the division of federal administrative organizations due to the relocation of capital to Berlin after German reunification and analyze the administrative problems and responses of the German government in depth in order to benchmark transferable solution. In result, the division of the federal administrative organizations was decided to compensate for the old capital Bonn, and it is in the form of horizontal division into the concept of main office and sub office buildings. Problems derived from this organiational division has been solved by approaching from the aspect of improving technical proximity using IT network and video conference room. On the other hand, in addition to the efforts made by the executive branch, the legislature also exercised active supervision rights, such as imposing a duty to submit division expenses reports to the administration, It was able to confirm the efforts in the aspect of organizational proximity such as carrying out the administrative affairs of the parliament in cooperation with the administration such as the limitation of the personnel. Based on these implications, possible lessons for Korean administration are discussed.

A comparison of higher education reform in South Korea and Germany
허준영,베시도나타 서울대학교 교육연구소 2013 Asia Pacific Education Review Vol.14 No.2
In this article, we compare two recent university reform projects: the Korean Brain Korea 21 project and the German Universities Excellence Initiative. We describe and compare both projects’ goals, selection processes, and preliminary outcomes. While the Korean project is characterized by a relatively high level of political intervention and can be seen as mainly a human resources development program with clearly defined strategic goals, the German tradition of university autonomy is also reflected in the reform project analyzed here. The project goal is more vaguely defined for the German project, but lies mainly in the field of research capacity building. Another key difference is the time horizons in both projects and the resulting incentives for publication and chosen research projects: while the Korean projects are evaluated on a yearly basis, the German projects have a longer time horizon for evaluation. A preliminary evaluation shows that both programs have succeeded in increasing publication output in the respective countries. However, an analysis of the quality of the new publications by, for example, their citation numbers, remains to be done in the future.

고속온오프밸브를 사용한 서보인텍싱시스템의 슬라이딩모드제어에 관한 연구
허준영 韓國技術敎育大學校 1994 論文集 Vol.1 No.1
This study deals with an electrohydraulic servo indexing system of a flexible forging center, which is operated by four 2-way high speed solenoid valves in the PWM digital mode. A flexible forging center consists of a forging machine and a indexing system. The role of the indexing system is to rotate a workpiece fast and accurately to a desired position. There are practical problems to be solved in this system, such as variations of system parameters during each forging step and serious nonlinearities in the valve characteristics. In order to overcome such problems, a sliding mode control is proposed. The salient feature of the sliding mode control is that the sliding mode occures on a switching surface. While in sliding mode, the system remains insensitive to parameter variations and disturbances. So robust performance can be achieved. In addition, this controller has a strategy to use an integrator to eliminate significant nonlinearities, such as the dead zone, which regularly appear with an PWM operated servo system. The dynamic characteristics of the system driven by the proposed method are investigated by digital simulation. Consequently, the availability of the proposed method is confirmed well.
