This study identified the tendency of CO₂ emission in energy consumption, cause of climate change, by analyzing the dynamic convergence regression model and decoupling analysis from 2013 to 2019 in regional level. In addition, CO₂ emission factors and contribution rates were derived by constructing an temporally and spatially expanded Log Mean Divisia Index(LMDI) model which was expanded in terms of time and space. According to results, firstly, CO₂ emissions in total energy use were found to gradually converge, and in particular, CO₂ emissions were reduced by the use of renewable energy. Secondly, as a result of decoupling analysis by industry/region to identify environmental changes compared to economic growth, the environmental factors of the primary industry were improved compared to economic growth in Honam region. In addition, the degree of environmental improvement of secondary industry according to economic growth by region was classified as revealing decoupling occurred in regions except for the Yeongnam region. Thirdly, it was identified that CO₂ emissions were reduced through renewable energy, R&D investment, and investment in the environment sector by deriving the determinants of CO₂ emissions. Finally, in the case of applying spatial gap, the metropolitan and Yeongnam regions, which have relatively higher economic power, reduced CO₂ emissions due to renewable energy, R&D investment, and investment in the environment sector. On the other hand, in Honam and Chunggang regions, which have relatively low economic power, CO₂ emissions decreased due to economic growth and population in addition to investment in renewable energy and the environment.

박승규(Seungkyu Park) 한국문화경제학회 2019 문화경제연구 Vol.22 No.1

삶의 질에 대한 관심은 지속적으로 증대하고 있으며, 최근 일과 삶의 균형으로 인해 문화 및 여가활동에 대한 중요도가 점차 증대되고 있다. 반면, 중앙 및 지방정부에서 공급하는 문화 및 여가 환경에 대한 주민들의 체감 정도는 파악하기가 쉽지 않다. 따 라서, 본 연구는 (현)대통령직속균형발전위원회의 229개 시군구 대상 6,920개의 지역 주민 행복도 조사를 활용하여 지역별 주민 삶의 질에 미치는 결정요인을 파악하며, 이 중 문화부문에 대한 추가적인 정부투자를 통한 문화부문 재정지원의 거시경제적인 영 향을 실증적으로 파악하는 것을 연구의 목적으로 한다. 분석결과 지역간 문화시설에 대한 객관적인 시설 총량 및 주관적인 만족도의 격차가 지역별로 여전히 존재하였다. 반면, 서비스의 특성에 따라 유사한 서비스의 경우 지자체 간 권역 설정을 통한 서비스의 공동 공급 및 사용으로 삶의 질은 향상되며 특히, 문화· 복지·의료 분야에서의 지역격차는 감소하는 결과가 나타났다. 더불어, 생활편의시설 공 급에 비해 상대적으로 중요도가 낮게 평가되었던 문화부문에 대한 재정지원을 정부투자 에 따른 소비세 감소, 지원금 증가, 자본확충 증가로 고려할 경우 문화부문에 대한 정부 투자는 문화부문 가격의 감소에 따른 소비 진작으로 가계의 효용이 증가되는 결과가 도 출되었다. 따라서, 본 연구는 주민 삶의 질에 영향을 미치는 문화부문에 대한 만족도는 문화부문에 대한 정부투자 증가로 인해 증가될 수 있는 실증적인 결과를 제공하였다. The interest in quality of life is steadily increasing and the importance of culture and leisure activities is increasing due to recent work-life balance. On the other hand, it is difficult to grasp the residents perceptions of cultural and leisure environment supplied by central and local governments. Therefore, the purpose of this study is to determine the determinants of local residents quality of life by using 6,920 local residents’ happiness survey of 229 cities and districts by Presidential Committee for Balanced Regional Development, and to empirically grasp the macroeconomic effects of financial support for culture sector. As a result, there is still regional disparity in objective facilities and subjective satisfaction for cultural facilities. However, in case of similar services according to characteristics of service, quality of life is improved by joint supply and use of services in regional level, and the regional disparities in culture, welfare, and medical care have decreased. In addition, government investment in the cultural sector, such as decrease in consumption tax, increase in financial support, and capital raising, was considered to reflect the increase of government investment through the financial support for the cultural sector have been relatively low importance rated compare to living facilities. As a result, the decrease in the price contrast to the increase of consumption led to increase of utility in the household. Therefore, this study showed that the resident’s satisfaction of the cultural sector was increased due to the increase of the government investment in the cultural sector.

In order to find the role of human capital accumulation of general and technical vocational education on regional economies from 1992 to 2017, this study used Ramsey-Cass-Koopmans model and panel system to empirically estimate the relationship of the school-age population, which affected to the human capital by technical vocational education, and total fertility rate. In the Seoul metropolitan area (SMA), the steady-state of regional economic factors increased due to the human capital accumulation through technical vocational education of general school. On the other hand, the steady-state of regional economic factors in non-capital area (ROW) also increased due to the human capital accumulation of general and technical vocational education. In addition, changes in human capital due to general vocational education have increased the steady-state of regional economic factors by population inflow, increase of the number of marriages, and gross domestic product per capita, but has been reduced by prices in both SMA and ROW. On the other hand, changes in human capital due to technical vocational education have led to an higher increase in the steady-state of regional economic factors due to an increase in population inflows, GRDP per capita, and marriages except price change in ROW.

고속 RISC 프로세서를 위한 가상 캐쉬 구조

본 논문에서는 캐쉬 액세스 시간이 direct-mapped 캐쉬와 같이 빠르면서, 캐쉬 성공율은 set-associative 캐쉬 처럼 높은, 고속 RISC 프로세서를 위한 새로운 가상 캐쉬 구조를 제안 한다. 이 구조에서는 전체 캐쉬 메모리를 n개의 뱅크로 나누고, 각 프로세스 생성시에 n개의 뱅크들 중에서 한개를 할당한다. 그러면, 각 프로세스는 자신에게 할당된 뱅크상에서 주로 수행되며, 그 뱅크상에서는 마치 direct-mapped 캐쉬처럼 동작 된다. 캐쉬 대치시에는 가장 늦게 스케쥴될 프로세스의 캐쉬라인을 희생 캐쉬로 선정하기 때문에 효과적인 대치가 이루어 진다. 트레이스 구동 모의실험 결과는 새로운 캐쉬 구조가 set-associative 캐쉬처럼 많은 충돌실패가 제거될뿐 아니라 캐쉬 액세스 시간이 direct-mapped 캐쉬 처럼 빠르다는 것을 보여 주고 있다. In this paper, we propose a new virtual cache architecture for fast RISC processors whose average access time is comparable to that of the direct-mapped cache while the hit ratio is the same as the set-associative cache. The entire cache memory is divided into n banks, and each process is assigned to a bank when it is created. Then, each process runs on the assigned bank, and the cache behaves like a direct-mapped cache. A victim for cache replacement is selected from those that belong to a process which is least likely to be scheduled in the near future. Results from trace-driven simulations confirm that the new scheme removes almost as many conflict misses as does the set-associative cache, while cache access time is similar to a direct-mapped cache.

‘지리를 가르친다’는 것의 인문학적 의미

박승규(Seungkyu, Park) 대한지리학회 2019 대한지리학회지 Vol.54 No.1

이 연구는 지리를 가르친다는 것에 대한 인문학적 의미를 탐색한다. 지리를 가르친다는 것이 학교의 일상적 행위이기 때문이 아니다. 지리를 가르친다는 것에 대한 존재론적 고민 때문이다. 지리를 가르친다는 것은 지리학의 본질에 다가가는 것이다. 지리학의 본질은 땅에 새겨져 있는 흔적을 토대로 인간과 공간의 관계에 대해 살펴보는 것이다. 인간을 대상으로 하는 지리교육이기에 인간의 삶에 대한 관심은 지속하여왔다. 인간의 삶에 대한 이해 역시도 지리를 가르치는 과정에서 중요한 요소였다. 그런 점에서 지리를 가르친다는 것은 인문학적 의미를 담고 있다. 쓸모있고 실용적인 지리적 지식에 대한 교육을 넘어, 진학이나 취직과는 무관한 쓸모없는 무형의 가치를 지닌 지리적 지혜를 가르치는 것, 그것이 지리를 가르친다는 것에 대한 인문학적 의미인 것이다. 나아가, 지리를 가르친다는 것에 대한 존재론적 논의는 지리교육의 존재론적 논의로 연장되고 확장될 수 있다는 점에서 의미가 있다. This study explores the humanities meaning of teaching geography. Teaching geography is not because it is a routine activity of the school. It is because of ontological worries about teaching geography. Teaching geography is about reaching the essence of geography. The essence of geography is to look at the relationship between man and space on the basis of the traces carved on the ground. As it is a geography education for human beings, interest in human life has been continued. Understanding human life was also an important factor in teaching geography. In that respect, teaching geography has the humanities meaning. Beyond education on useful and practical geographical knowledge, teaching geographical wisdom with useless intangible values that are not related to further study or employment, it is the humanities meaning of teaching geography. Furthermore, the ontological discussion of teaching geography is meaningful in that it can be extended and extended to ontological discussion of geography education.

좌심실보조장치의 모델과 안전한 장치 구동을 위한 흡입현상 검출을 위한 방법을 제안한다. 좌심실보조장치인 축류혈액펌프는 심장에 문제가 있는 환자를 보조하기 위하여 사용되어 왔다. 축류혈액펌프는 비맥동성 펌프이며, 맥동성 펌프에 비하여 작은 크기와 효율성과 같은 장점이 있으나, 안전한 펌프 운전 조건을 결정하는 데 어려움이 있다. 축류혈액펌프는 정상상태와 흡입상태와 같은 상이한 펌프 동작 상태를 가지며, 이는 좌심실에서 흡입현상 발생여부에 좌우된다. 퍼지 subtractive 클러스터링 기법을 이용하여, 이와 같은 동작 특성을 가지는 축류혈액펌프 모델을 개발하며, 개발한 펌프 모델을 이용하여 흡입현상 발생 전후의 펌프 혈류량을 추정한다. 또한 퍼지 subtractive 클러스터링 기법을 이용하여 좌심실에서 흡입현상 발생여부를 감지할 수 있는 흡입현상 검출 모델을 개발한다. A method to model left ventricular assist device (LVAD) and detect suction occurrence for safe LVAD operation is presented. An axial flow blood pump as a LVAD has been used to assist patient with heart problems. While an axial flow blood pump, a kind of a non-pulsatile pump, has relative advantages of small size and efficiency compared to pulsatile devices, it has a difficulty in determining a safe pump operating condition. It can show different pump operating statuses such as a normal status and a suction status whether suction occurs in left ventricle or not. A fuzzy subtractive clustering method is used to determine a model of the axial flow blood pump with this pump operating characteristic and the developed pump model can provide blood flow estimates before and after suction occurrence in left ventricle. Also, a fuzzy subtractive clustering method is utilized to develop a suction detection model which can identify whether suction occurs in left ventricle or not.

The purpose of this study is to identify the growth changes in the steady state due to changes of industrial product variety by a Schumpeterian growth model. In addition, the degree of convergence of productivity(TFP), including quantitative and qualitative sectors, was confirmed by a dynamic panel convergence regression model, and growth change in a steady state were simulated by population, R&D investment(R&D), and industrial product variety. As a result, industrial product variety increased due to the increase of new industries, total fertility rate(TFR), the degree of aging, and the working age population from 2005 to 2019. In addition, qualitative technological progress, quantitative industrial product variety, and TFP converged over time. Economics growth was parallel to R&D, and increased by industrial product variety, production factors, and TFP. And the LR/SR growth effects were identified through the increase in the TFR and working age population. Lastly, industrial product variety by the creation and distinction of businesses induces growth. Therefore, economic growth is induced in proportion to R&D, immediate change in growth were attained by in the order of change in the number of business, the working age population, and TFR.
