재난 등에서 발생하는 대형 폐기물에 대한 효율적인 관리가 지속적으로 요구되고 있다. 대형 폐기물은 환경과 밀접하게 연결되어 대기질이나 수질, 생활 환경 등에 악영향을 미치고 있다. 대형 폐기물이 발생하면 임시적환장으로의 이동이나 처리 등을 위해서 발생량을 추정할 수 있어야 한다. 현재까지 위성영상이나 폐기물의 원단위를 이용하여 발생량을 추정하고 있지만 그 정확성에 대한 의문이 지속적으로 제기되는 실정이다. 따라서 본 연구에서는 UAS를 기반으로 3차원 공간정보를 구축하고 폐기물 측정 및 정확도 평가를 목적으로 연구를 진행하였다. UAS를 이용하여 폐기물 지역을 측정한 결과, 3차원 공간정보의 X, Y, Z RMSE 수치는 각각 0.022 m, 0.023 m, 0.14 m로 비교적 높은 정확도를 보였다. 이를 기반으로 측정한 폐기물량은 약 $4,273,400m^3$로 도출되었다. 또한 과거부터 지형, 문화재 등 정밀한 측량에 사용된 지상 LiDAR를 이용하여 동일지역의 폐기물량을 측정하였으며 그 결과값은 약 $4,274,188m^3$로 도출되었다. UAS 기반으로 도출한 폐기물량과 크게 차이를 보이지 않았다. 이를 통해 UAS를 이용한 폐기물 발생량 측정에 대한 가능성을 확인할 수 있었으며 이는, 재해 폐기물이나 대형 폐기물 등의 환경관리에 유용하게 활용될 수 있을 것으로 사료된다. Efficient management of large-size wastes generated from disasters etc. is always in demand. Large-size wastes are closely connected to the environment, producing adverse effects on the air quality, water quality, living environment and so on. When large-size wastes are generated, we must be able to estimate the generated amount in order to transfer them to a temporary trans-shipment site, or to properly treat them. Currently, we estimate the amount of generated large-size wastes by using satellite images or unit measure for wastes; however, the accuracy of such estimations have been constantly questioned. Therefore, the present study was performed to establish three-dimensional spatial information based on UAS, to measure the amount of waste, and to evaluate the accuracy of the measurement. A measurement was made at a waste site by using UAS, and the X, Y, Z RMSE values of the three-dimensional spatial information were found to be 0.022 m, 0.023 m, and 0.14 m, all of which show relatively high accuracy. The amount of waste measured using these values was computed to be approximately $4,273,400m^3$. In addition, the amount of waste at the same site was measured by using Terrestrial LiDAR, which is used for the precise measurement of geographical features, cultural properties and the like. The resulting value was $4,274,188m^3$, which is not significantly different from the amount of waste computed by using UAS. Thus, the possibility of measuring the amount of waste using UAS was confirmed, and UAS-based measurement is believed to be useful for environmental control with respect to disaster wastes, large-size wastes, and the like.

본 연구는 도시공원 공간적 분포의 문제점을 도시공원 서비스권역과 주소별 주민등록 데이터를 사용한 분석을 통해 밝히고자 하였다. 도시공원 중 "도시공원 및 녹지 등에 관한 법률"에 의해 지정된 "거주자의 보건 휴양 및 정서생활의 향상에 이바지 하기 위해 설치"된 근린공원을 대상으로 하였다. 연구 방법은 크게 1) 근린공원 서비스권역 분석, 2) 근린공원 서비스권역 내 외 인구분석, 3) 기존 연구와의 비교 검토로 구분하여 분석하였다. 기존 연구들에서 나타났던 거주민 분석의 한계를 개선하고자 차별성을 두어, 각 주소별로 등록된 거주민 주민등록 데이터를 활용하여 실제 거주하는 주민수를 적용하였다. 근린공원 서비스권역 또한 기존에 주로 사용되었던 직선거리를 적용한 버퍼분석이 아닌 보행로, 새주소길 등을 적용한 네트워크 분석을 이용하였다. 이상의 과정을 통하여 도출한 결과, 근린공원 서비스권역 면적은 전체면적의 7.99%의 비율을 보였으며, 전체 주거지역 중 근린공원 서비스권역 면적은 31.23%의 비율을 보였다. 근린공원 서비스권역 내에 거주하는 인구는 대구광역시 인구의 43.03%만이 거주하고 있는 것으로 나타나, 전체 인구 반 이상의 인구가 서비스권역 외에 거주하는 것으로 나타났다. 마지막으로 기존 연구방법과의 비교 검토 결과는 근린공원 서비스권역 및 서비스권역 내 외 인구 수치에서 큰 차이를 보였다. Urban parks are public spaces that provide various services for any urban resident to use and enjoy. Parks should be fairly distributed so that the urban parks can be equally used amongst different regions, generations and classes. Researches on spatial distribution of urban parks have been continuously conducted from the past based on the principles of fairness with variety, and it was evident that their techniques have become more elaborate and sophisticated. Yet, there have been limitations in the analysis of residents who are the main users of the urban parks. The research done so far was unable to apply the real number of the residents and it was carried out by only classifying and analyzing the population by the same scale(grid in the same sizes), postal(zip) code and administrative district. The actual population that resides within the usable range of urban parks was not used. This study analyzes and evaluates the spatial distribution that the residents can use on foot, by utilizing the service areas and the residents' registration data by addresses. In this study, to analyze the square measure of the service areas of neighborhood parks in Daegu Metropolitan City and the number of residents within and outside of the service area, network analysis techniques were employed and the residents' registration data were utilized. Major findings were that the Square measure of service areas of neighborhood parks turned out to be 31.23% of the square measure of the residential areas and also, that only 43.03% of the population of the Daegu Metropolitan area lives within the service areas of the neighborhood parks.

로드킬 발생 영향요인 분석 - 설악산 국립공원 44번 국도를 대상으로 -

손승우,길승호,윤영조,윤정호,전형진,손용훈,김민선,Son, Seung-Woo,Kil, Sung-Ho,Yun, Young-Jo,Yoon, Jeong-Ho,Jeon, Hyung-Jin,Son, Young-Hoon,Kim, Min-Sun 한국조경학회 2016 韓國造景學會誌 Vol.44 No.3

본 연구는 설악산 국립공원 내 44번 국도를 대상으로 로지스틱 회귀분석을 실시하여 로드킬이 발생한 지역의 공간적 특성을 분석하고, 분석 결과의 적합도 및 예측도를 평가하여 로드킬 발생 근본 원인을 파악하고자 하였다. 2008년부터 2013년까지 구축된 81개의 로드킬 데이터를 종속변수로 설정하고, 선행연구 및 현장조사를 통해 도출한 경사, 향, 식생, 백두대간 등의 자연환경 요인과 펜스 옹벽 등의 인공시설물, 경작지, 주거지역 등의 토지이용 변수를 독립 변수로 설정하고, 로지스틱 회귀분석을 실시하여 회귀식을 추정하였다. 식생 영급, 하천으로부터의 거리, 펜스 옹벽 등의 설치구간, 주거지역 건물 등의 시설로부터의 거리가 로드킬에 영향을 미치는 변수로 선택되었다. 회귀모형에 포함된 모든 변수들은 유의수준(p<0.01)을 충족하였다. 회귀모형에서 로드킬 발생에 가장 큰 영향력을 보인 변수는 펜스 옹벽 등의 설치구간(회귀계수: -1.0135)으로 나타났으며, 가장 낮은 영향력을 보인 변수는 식생 영급(회귀계수: 0.0001)으로 나타났다. 즉, 펜스 옹벽 등의 설치 구간에서는 로드킬이 일어날 확률이 낮으며, 주거지역 건물 등의 시설로부터의 거리가 가까울수록, 하천으로부터의 거리가 가까울수록, 식생 영급이 커질수록 로드킬 발생이 높아질 수 있다. 추정된 로지스틱 회귀모형 결과로부터 로드킬이 일어날 것이라고 옳게 예측한 확률은 74.1%, 로드킬이 일어나지 않을 것이라고 옳게 예측한 확률은 70.4%로 나타났다. 전체적으로는 옳게 분류한 확률은 72.2%로 비교적 높은 비율을 보였다. 본 연구를 통해 로드킬 저감을 위한 계획 및 정책 수립, 방지시설 설치 계획 등의 공간의사 결정에 객관적 근거로 도움을 줄 수 있을 것으로 사료된다. This study aimed to interpret the fundamental cause of road-kill occurrences and analyzed spatial characteristics of the road-kill locations from Route 44 in Seorak National Park, Korea. Logistic regression analysis was utilized for backward elimination on variables. Seorak National Park Service has constructed GIS-data of 81 road-kill occurrences from 2008 to 2013 and these data were assigned as dependent variables in this study. Considered as independent variables from previous studies and field surveys, vegetation age-class, distance to streams, coverage of fences and retaining walls, and distance to building sites were assigned as road-kill impact factors. The coverage of fences and retaining walls(-1.0135) was shown as the most influential factor whereas vegetation age-class(0.0001) was the least influential among all of the significant factor estimates. Accordingly, the rate of road-kill occurrence can increase as the distance to building sites and stream becomes closer and vegetation age-class becomes higher. The predictive accuracy of road-kill occurrence was shown to be 72.2% as a result of analysis, assuming as partial causes of road-kill occurrences reflecting spatial characteristics. This study can be regarded as beneficial to provide objective basis for spatial decision making including road-kill occurrence mitigation policies and plans in the future.

IBM의 지식재산 라이선스 거절에 대한 독점금지법의 적용 검토

손승우 ( Son Seung-woo ) 한국외국어대학교 법학연구소 2011 외법논집 Vol.35 No.4

The U.S. Department of Justice has been investigated allegations that IBM abused its dominance of the mainframe computer market to harm rivals by refusal to license for its operating systems to customers who use non-IBM hardware, retaliating against business partners deemed disloyal and bundling its mainframe operating systems with hardware. It involved a selective refusal to license its patented technology to the software developers (FSI and PSI), which was an essential factor in developing a platform supporting IBM’s mainframe operating system. As a result, the competition in the mainframe platform market was harmed, and thereby denies consumers the freedom to choose. Although the U.S. District Court dismissed T3’s claims against IBM, the DOJ and the Second Circuit has reviewed the case again as the decision was open to criticism. This is a significant opportunity to draw a clearer line whether an unilateral refusal to deal in a lawfully patented product violates an antitrust law since Microsoft case of a decade ago. In September of 2011, IBM offered a concession to European regulators, including a commitment to make spare parts and technical information easier for competitors to provide maintenance services for its mainframe computer. As the EU decided to close an antitrust probe against refusal to deal, the unlawfully tying its mainframe hardware with its operating system is now under question. This article examines the IBM decision more critically, and emphasizes that the selective or discriminatory refusal to license patented technology, which is an essential element to competitors in adjacent market, could bring a more anti-competitive effects than other types of refusals. On this point, the European approach and standard is more reasonable and clearer for decide the legality of an unilateral refusal to license intellectual property. It also addresses some of issues on compulsory license as a remedy for refusal behavior.

지적재산권과 경쟁법의 변증법칙 -미국 "IP-경쟁" 정책의 역사를 중심으로-

손승우 ( Seung Woo Son ) 중앙대학교 법학연구원 문화.미디어.엔터테인먼트법연구소 2009 문화.미디어.엔터테인먼트 법 Vol.3 No.2

A history of conflicts between competition law and intellectual property has been long and complex. The interface between these laws has always presented obvious tensions. The former restrains anti-competitive conduct, and fosters a competitive marketplace, while the latter promotes innovation by granting an intellectual property holder the right to limit competition. Nevertheless, both antitrust law and IP laws share a common economic goal such as maximizing consumer welfare and encouraging innovation and competition, but achieve it by employing different approaches. Even the United States that experienced a great number of cases regarding this issue historically repeated between over-and under-protection with antitrust and IP. To achieve the goal most effectively, these laws should strike a balance in contradicted relationship between IP protection and competition; private rights and public interest; and exclusive dealing and access. However, the recent competition policy on intellectual property in U.S. has attempted to maximize the national wealth with a stronger IP protection rather than imposing antitrust value that should be desirable for promoting innovation. Much economic literature suggests that innovation is best promoted by preserving competitive processes and market environment over the long run, and antitrust law does play a direct and important role. Accordingly, it is necessary to strengthen antitrust enforcement in order to curb IP misuse and to strike a delicate balance between these laws as well. This paper examines the dialectic history and the current problems of interaction between intellectual property and antitrust law, and suggests that necessity of a new balance between these two bodies of laws, which provides a desirable direction to the Korean competition policy on intellectual property.

드론을 이용한 토지이용별 미세먼지 농도 측정 가능성 모색 연구

손승우(Seung-Woo Son),유재진(Jae-Jin Yu),김동우(Dong-Woo Kim),김태현(Tae-Hyun Kim),성웅기(Woong-Gi Sung),윤정호(Jeong-Ho Yoon) 한국산학기술학회 2020 한국산학기술학회논문지 Vol.21 No.4

본 연구에서는 원하는 시간과 장소에서 데이터 수집이 용이한 드론에 미세먼지 측정 센서를 부착하여 3가지 측정환경인 건설현장, 자연환경(수목원), 주거지역에서 고도(30m, 60m, 90m, 120m, 150m)에 따른 미세먼지 농도를 측정하고 비교하였다. 건설현장 30m 지점의 PM2.5와 PM10 측정값은 각각 18.63㎍/㎥, 24.23㎍/㎥, 150m 지점의 PM2.5와 PM10 측정값은 각각 10.89㎍/㎥, 10.61㎍/㎥로 고도가 높아질수록 평균 농도가 낮아지는 것으로 나타났다. 자연환경(수목원) 30m 지점의 PM2.5와 PM10 측정값은 각각 9.03㎍/㎥, 11.21㎍/㎥, 150m 지점의 PM2.5와 PM10 측정값은 각각 3.42㎍/㎥, 3.57㎍/㎥로 고도가 높아질수록 평균 농도가 낮아지는 것으로 나타났으나, 모든 지점의 PM2.5와 PM10 측정값은 비슷한 것으로 나타났다. 주거지역 30m 지점의 PM2.5와 PM10 측정결과는 각각 10.65㎍/㎥, 12.06㎍/㎥, 150m 지점의 PM2.5와 PM10의 측정값은 각각 4.24㎍/㎥, 5.17㎍/㎥로 고도가 높아질수록 대체적으로 PM2.5와 PM10 농도가 낮아짐을 확인하였다. 주거지역의 경우 건설현장이나 수목원에 비해 교통량이 많은 도로에 인접해 있어 PM2.5의 농도가 PM10의 농도보다 높게 나온 것으로 사료된다. 세 대상지 모두 고도가 상승할수록 PM2.5와 PM10의 농도가 감소하는 추세를 보였다. 또한, 건설현장, 주거지역, 자연환경(수목원) 순으로 PM2.5와 PM10의 농도가 높은 것으로 확인하였다. 본 연구의 결과는 토지이용별로 미세먼지 농도값을 고도별로 측정하였다는데 의의가 있으며, 지역계획이나 도시계획 등에서 중요한 공간의사결정 기초자료로 활용될 수 있을 것으로 사료된다. This study measured the Particulate Matter (PM) concentration according to altitude (30 m, 60m, 90 m, 120 m, and 150 m) in three different environments: a construction site, natural environment (arboretum), and residential area. PM2.5 and PM10 values at 30 m above the construction site were 18.63 μg/m³ and 24.23 μg/m³ while values at 150 m were 10.89 μg/m³ and 10.61 μg/m³, respectively, indicating the average concentration decreased as altitude increased. PM_2.5 and PM₁₀ values at 30 m above the natural environment were 9.03 μg/m³ and 11.21 μg/m³ while those at 150 m were 3.42 μg/m³ and 3.57 μg/m³, respectively, showing lower average concentrations as altitude increased. PM2.5 and PM10 values at 30 m above the residential area were 10.65 μg/m³ and 12.06 μg/m³ while those at 150 m were 4.24 μg/m³ and 5.17 μg/m³, also demonstrating lower PM concentrations as altitude increased. The PM concentrations decreased as altitude increased at all tested sites and also decreased between environments in the following order: construction site, residential area, and natural environment. The results of this study are significant because PM concentrations were measured at various altitudes at different land-use sites. The results are expected to serve as basic data for decision-making in both regional and urban planning.

As one of the Five IP Offices(IP5), Korea has maintained world-class level in a creation and protection of Intellectual Property. However, when it comes to create value by taking advantage of the created IP, it falls short of expectations. For these reasons, the recent policy of the government`s research and development, and technology and intellectual property is concentrated on commercialization. Support commercialization of intellectual property policies of the government, which is run mostly on the legal foundation, such as Technology Transfer and Commercialization Promotion Act, The Framework Act on Intellectual Property, Invention Promotion Act, Industrial Technology Innovation Promotion Act, Framework Act on Science and Technology, Regulations on Management of national Research and Development Projects, etc. These laws include a variety of programs and institutions for the commercialization. For example, specialized technology commercialization company, technology evaluation, technology holding company, finance, technology trust, technology start-ups specializing in company, asset-backed securitization, gratuitous donation, etc. The commercialization policy has been implemented by various government agencies such as the commercialization of research and development by the Ministry of Education, Science and Technology, industrial property commercialization by the Patent and Trademark Office, and the commercialization of the technology industry by the Ministry of Knowledge Economy, and the commercialization of the technology-related venture company by the Small & Medium Business Administration. Therefore, IP(including technology) commercialization in relevant laws can be overlapped, and the organic connection may not be enough. For instance, the Framework Act on Science and Technology does barely address facilitating commercialization of intellectual property from the research and development stage. This paper provides the basic comprehensive review of the relationship of the laws and institutions related to intellectual property rights commercialization. It examines inefficiency caused by redundant regulations of commercialization, and non-legislative space as well. It also suggested the necessity for a further study on comprehensive analysis on the legal system for the commercialization of intellectual property.
