박현준,차의영,Park, Hyun-Jun,Cha, Eui-Young 한국정보통신학회 2007 한국정보통신학회논문지 Vol.11 No.6

본 논문에서는 신경회로망 알고리즘 중 하나인 backpropagation network을 이용한 악보인식 기법과 그에 필요한 악보 영상에 대한 전처리 기법을 제안한다. 전처리과정으로 이진화, 기울기 보정, 오선제거 등의 과정을 수행하여 인식에 필요한 음악 기호와 음표를 분리한다. 분리된 음악 기호와 음표들은 backpropagation 알고리즘을 사용하여 구성된 음표 인식 신경망과 비음표 인식 신경망을 통해 각각 음표와 비음표 인식과정을 거친다. 다양한 복잡도를 가진 악보를 대상으로 한 실험 및 분석 결과를 통해 제안한 악보 인식 기법의 정확도를 기술하였다. This paper presents techniques to recognize music using back propagation network one of the neural network algorithms, and to preprocess technique for music mage. Music symbols and music notes are segmented by preprocessing such as binarization, slope correction, staff line removing, etc. Segmented music symbols and music notes are recognized by music note recognizing network and non-music note recognizing network. We proved correctness of proposed music recognition algorithm though experiments and analysis with various kind of musics.

Urinary Tract Symptoms (LUTS) Secondary to Benign Prostatic Hyperplasia (BPH) and LUTS/BPH with Erectile Dysfunction in Asian Men: A Systematic Review Focusing on Tadalafil

박현준,Ji Eon Joanne Won,Sebastian Sorsaburu,Paul David Rivera,이승욱 대한남성과학회 2013 The World Journal of Men's Health Vol.31 No.3

This review assesses lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) with or without erectile dysfunction (ED) and related therapies focusing on tadalafil. A literature search was obtained and reviewed for the epidemiology, treatment therapies, pathophysiology, and efficacy and safety of phosphodiesterase type 5 inhibitor (PDE5i) tadalafil in patients with LUTS/BPH. Approximately 42% of men aged 51 to 60 years have BPH. Approximately 90% of men aged 45 to 80 years have LUTS. Occurrence of LUTS increases with age for almost all racial/ethnic groups (range, 32% to 56%) with prevalence of LUTS highest among Hispanic men, then Blacks, Caucasians, and Asians. There is an independent relationship with LUTS/BPH and ED, with approximately 70% of men with LUTS/BPH having ED with severity of one disease often correlating with the other. The European Urological Association guidelines include the use of the PDE5i tadalafil. Tadalafil is the only therapy recommended for treatment of co-existing BPH and ED, while other therapies have unwanted ED side effects. The mode of action of tadalafil may involve different areas of the lower urinary tract such as smooth muscle cell relaxation in the bladder neck, prostate, and urethra, but there may also be resulting modulation of the afferent nerve activity. Tadalafil (5 mg) in Asian men with LUTS/BPH, similar to global studies, is efficacious and safe. Tadalafil (5 mg) improves co-existing LUTS/BPH and ED, independently. Men with LUTS/BPH likely also have ED. Asian men with LUTS/BPH have similar incidence rates, co-existing ED, comorbid diseases, and risks as non-Asian men. Tadalafil can improve co-existing LUTS/BPH and ED.

Today, problems of drug abuse becomes a serious social problem not limited to a certain social group. Among the various social problems caused by the drug abuse rapidly increasing drug addicted juvenile is the most serious social problem since it threatens to the national security. That is, drug abuse is not only a personal problem which causes a self destruction but also a social problem which induces a crisis for the society. However, despite of the seriousness of drug abuse people seems to consider the troublesome of drug abuse not so sincerely as it really is. Though there might be a some real connection between the collapsing moral standard in our society and increasing number of drug problems it seems to be a clear that biased public perception over the drug abuse might have caused the rapid dispersion of drug addict and have loosed the government effort to restrict the dispersion of drug problems. Because of the powerful poison of drug to a human body the best way to solve and to limit drug problem is the blocking of public approach to drug. From this perspective this study shows that controlling social demand for the drug is more effective than blocking drug distribution in the society. In this regard this study presents some possible alternatives to control the social demand for the drug in terms of public administration and law enforcement. First, in order to diminish social demand for a drug we should strengthen public education and public advertisement regarding the serious problems of drug abuse. Second, we should give prior to addiction therapy than the law enforcement to control social demand for a drug for a long perspective. Third, government should develop new ways of investigation and keeping in order of drug related criminal cases such as introducing new reagent to investigate possible drug addict groups. Fourth, government should give a certain effort to manage new information about drug abuse and existing data for drug addict and construct systemized information management system. Finally, government should raise current indemnity given to drug related information provider to a certain degree to have useful information about the changes of social demand for the drug and etc.

DEA-SBM을 이용한 국내 로봇산업의 경영효율성 분석에 관한 연구 : 기술혁신요소를 중심으로

박현준,하정석,강연지,심우중 경성대학교 산업개발연구소 2017 산업혁신연구 Vol.33 No.2

최근 4차 산업혁명이 이슈가 되면서 로봇을 활용한 제조업의 스마트화 등이 본격적으로 추진되는 양상이다. 이에 본 연구는 국내 로봇산업의 기술혁신요소를 중심으로 기업의 경영효율성을 분석하고, 효율성 개선을 위한 우선 고려요소를 제시하였다. 투입요소로는 인건비, 무형자산, 유형자산, 경상연구개발비를 설정하였고, 산출요소는 매출액으로 하였다. 분석대상은 국내 로봇기업 32개사를 대상으로 하였고 효율성 분석방법인 DEA-SBM(Data Envelopment Analysis-Slack Based Measure)을 이용하였다. DEA-SBM 분석결과 로봇산업의 경영효율성은 평균적으로 57.6%인 것으로 나타났으며, 특히 무형자산 효율성이 가장 낮은 것으로 나타났다. 이는 국내 로봇산업의 비효율 개선을 위해서는 무형자산 측면의 효율 개선을 우선적으로 고려할 필요가 있음을 의미한다. 본 연구의 분석결과는 지능형로봇 개발이 강조되는 최근 로봇산업의 트렌드와 연결된다. 무형자산은 기업의 지식자산 및 지식기반역량과 밀접하게 연관되며, 이는 지능형로봇 구현을 위한 핵심적 요소이기 때문이다. 현재까지 비교적 많은 국내 로봇기업이 지식기반역량을 확보하지 못하고 있는 것으로 나타났으며, 이에 따라 향후 국내 로봇산업 경쟁력 제고를 위한 지식기반 및 무형자산 역량 강화 전략 수립이 필요하다. As the fourth industrial revolution has recently been a major issue, the smart manufacturing with robotics has been pursued. Against this backgrounds, this study strived to analyze the management efficiency of businesses focused on a technology innovation factor of the domestic robotics industry, and suggested efficiency improvement as a major factor to consider. Inputs are labor costs, intangible assets, tangible assets, and ordinary research and development expense, while output is sales proceeds. The analysis targets are 32 firms in the domestic robotics industry. And DEA-SBM(Data Envelopment Analysis-Slack Based Measure) was chosen as an efficient analysis measure. As a result, management efficiency of robotics turned out to be 57.6% on average, and multiple firms demonstrated low intangible asset efficiency. It means that it is necessary to consider the efficiency improvement of intangible assets in order to enhance efficiency of businesses with inefficient operation. The analysis result of this study has relations with a recent trend of the robotics industry that highlights the development of intelligent robots. Intangible assets are closely related to knowledge assets and knowledge-based capacity of businesses, because they are core elements to realize intelligent robots. Relatively many domestic firms in the robotics industry have not secured knowledge-based capacity, so far. Therefore, it is urgently needed to establish a strategy to step up a knowledge-based and intangible asset related capacity to enhance the competitiveness in the domestic robotics industry in the future.

DEA와 Malmquist를 이용한 스마트공장 공급기업의 효율성과 생산성분석: 시스템·응용 소프트웨어 개발 및 공급업을 중심으로

박현준,심우중,이자연 경성대학교 산업개발연구소 2018 산업혁신연구 Vol.34 No.4

As the fourth industrial revolution becomes a hot topic, the importance of smart factories which is the center of manufacturing innovation is increasing. This study analyzed the change of management efficiency and productivity of smart factory suppliers that plays a key role in building smart factories. The purpose of this study is to estimate operational efficiency and productivity of supplier companies and to provide implications for the government's smart factory policy in South Korea. This paper analysis on the productivity and efficiency using companies last five years financial data which ‘Operate system and application software publishing(KSIC 5822)’ industry in the “pool of suppliers” of the Korea Smart Manufacturing Industry Association and Korea Smart Factory Foundation. First, as a result of the efficiency analysis using DEA, the average efficiency was analyzed to be rather lower than in 2012. Recently, PTE has increased while SE has decreased. Therefore, the scale of input should be improved. Second, the change in productivity by point of view according to Malmquist decreased productivity in the first period (2012-2013), the second period (2013-2014) and the third period (2014-2015). In the fourth period (2015-2016), it was analyzed that productivity increased as the effect of technology change improved. Finally, in order to improve the performance of smart factory suppliers, we should focus on efficient utilization of input resources rather than expanding the scale. In addition, although the overall productivity has improved, there is still a gap between leading companies and non-leading companies. Therefore, policy support measures such as development and dissemination of infrastructure technologies and joint research and development support are needed. 제4차 산업혁명이 화두가 되는 가운데, 제조혁신의 핵심인 스마트공장의 중요성이 높아지고 있다. 본 연구는 스마트공장 솔루션을 제공하는 스마트공장 공급기업의 경영효율성과 생산성 변화를 분석하였다. 이를 통해 국내 스마트공장 구축 진행 과정에서 공급기업의 효율성과 생산성의 변화를 추정하고, 나아가 정부의 스마트공장 정책 개선을 위한 시사점을 도출하고자 한다. 분석을 위해 한국스마트제조산업협회와 스마트공장추진단의 ‘공급기업 풀’에서 한국표준산업분류의 시스템․응용 소프트웨어 공급 및 개발업(5822)을 영위하는 기업의 최근 5년(2012-2016년) 기간의 재무정보를 이용하였다. 주요 분석결과는 첫째, DEA를 이용한 효율성 분석결과 평균 효율성은 2012년보다 오히려 낮은 것으로 나타났다. 최근 순수기술효율성은 증가한 반면 규모의 효율성이 하락하였다. 따라서 투입규모를 개선이 필요한 것으로 요구된다. 둘째, Malmquist 분석에 따른 시점별 생산성 변화는 1기(2012-2013), 2기(2013-2014), 3기(2014-2015)의 경우 생산성이 하락하였다. 반면 4기(2015-2016)에는 기술변화효과가 개선되면서 생산성이 증가한 것으로 분석되었다. 분석결과를 바탕으로 다음과 같은 시사점이 도출되었다. 스마트공장 공급기업의 성과 개선을 위해서는 규모의 확대보다도 투입 자원의 효율적 활용에 초점을 맞춰야 한다. 또한 전반적인 생산성은 개선되었으나 여전히 선도기업과 그렇지 않은 기업 간 격차가 벌어지고 있으므로 이를 개선하기 위한 기반기술 개발 및 보급, 공동 연구개발 지원 등 정책지원 방안이 필요하다.
