A tracer test technique using a radioisotope was proposed to investigate pollutant mixing characteristics in rivers. The main advantages of radioisotope as a tracer in field tests are that it can be detected easily, and that its detection range is quite large. Also, using the radioisotope, the amount sorbed by the bed material and the biota may be a minimum. Field tracer tests were conducted at seven different sites in natural rivers with various meandering pattern. Based on the acquired data, the behavior of the tracer cloud in the intermediate-field was examined two-dimensionally, and dispersion coefficients were calculated using several evaluation methods. Results revealed that the tracer cloud was transported skewed to the outer bank and dispersion coefficients in bends were larger than those in straight reaches.

최근 인공지능 시대 및 제 4차 산업 혁명 시대의 도래로 제품 간, 제품과 서비스 간, 서비스 간 산업이 다양한 형태로 진화 중이며, 이종기술 산업 간의 융 복합화로 새로운 제3의 신산업이 등장하고 있다. 또한 소위 말하는 O2O(Online to Offline)는 이미 운송, 금융(핀테크), 자동차(카테크), 숙박, 음식, 의료(헬스케어테크) 등 많은 산업 분야에 진출, 기존 전통 산업과 충돌, 인허가에 어려움을 겪고 있으며 이러한 O2O는 IOT(사물인터넷)로 급속도로 가속화 되고 있다. 이렇듯 4차 산업 혁명에 따른 신산업의 탄생은 산업의 경계를 붕괴하고 있음에도 산업별로 구분된 제도, 규제, 지원정책 등은 여전히 신산업 창업의 장애가 되고 있다. 이에, 본 연구에서는 국내 벤처특별법, 창업지원법, 1인 창조기업법 내 투자 지원 업종과 미국을 비롯한 해외 창업 관련법 내 창업 지원 제한 업종과의 비교 분석, 몇 가지 중요한 시사점을 도출했다. 먼저, 우리나라가 선진국에 비해 지나치게 투자 제한 업종이 많음을 확인했다. 또한 선진국은 미풍양속을 해치는 업종, 투기적 사업 등 사회통념상 문제가 되는 사행성 업종을 제외하고는 대다수의 업종이 정책 지원 대상이다. 업종과 더불어 투자 행위로 투자 심사를 해 신산업 투자에 매우 탄력적으로 운영할 수 있게 설계되어 있다. 심지어 미국의 경우, 적극적 창업 투자를 위해 업종 및 투자 행위에 대한 심의를 중소기업청이 직접 수행한다. 특히, 우리나라의 중소기업창업투자회사제도는 미국의 중소기업투자회사(SBIC) 제도와 유사한 반면 투자 제한 업종 뿐 아니라 제도 운영 특히, 창업투자회사에 대한 관리 측면에서 매우 큰 차이가 있음을 보여주고 있다. 우리나라 중기청은 간접관리를 하는 반면, 미국은 중기청 내에서 직접 관리를 하고 있다. 따라서 본 연구에서는 우리나라 창업 벤처 투자 제한을 미국을 비롯한 기타 외국의 사례에서와 같이 사회통념상 불가피한 업종과 더불어 투자 행위로 정의하길 제안한다.

The gift coupon system was introduced in the AWP(Amusement With Prize) Game Industry in February 2002 to revitalize the sluggish domestic game industry and establish the cultural industry base. Today, however, speculations regarding these coupons are fast becoming a serious social issue. Therefore, this study proposes the establishment of the MCTF Management System as a possible solution to the analysis and resolution of the problem of gift coupons aimed at promoting the AWP Game Industry and ensuring its soundness as well as bridging the gap between the domestic and international game markets in terms of the industrial structure; thus securing global competitiveness. Unlike any other measure taken to date to prevent speculations, the MCTF Management System can eradicate problems related to coupons offered for free in the AWP Game Industry. This strategic system consists of Merchandise Coupon Management, Central Management, Tripartite Guarantee Management, and Fund Management System. Finally, this system is expected to help root out the problems related to gift coupons.

Game industry is certain to change rapidly as its attribute. Therefore, It's not easy that the law response to reflect the technological change of game industry properly, and a new legal issue that is difficult to cover with the existing law. Recently, Court battle or cases about games are socially receiving attention. Nevertheless, Research accumulation about the legal action to response this is rare situation. The legal system that is related games mostly approach in the regulation and punishment of one-sided administration so far. Relatively, Approach from the game industry development and promotion act standpoint is low. Shrinking rapidly the current game industry is not an irrelevance to this. So It is necessary to reconstruct rationally in side that embrace with variety of views of members of the society and interests about current game-related laws, systems and regulation instruments. Access to how will develop competitiveness of the game industry in legal aspects and how will promote the balanced development between game industries are needed. The problems that needs to handle in legal aspect such as game development, game distribution, and game usage which in the part of the game industry are getting more and more in the future.

최근 기후변화로 강우량이 증가하면서 복잡한 수위, 소류력, 유속이 나타나는 하천의 만곡에서 여유고를 초과하여 호안의 유실 및 제방의 파괴가 발생하고 있다. 이러한 현상을 예방하기 위해 1차원 홍수유출 모형을 이용하여 직선하도의 수위와 유속 등을 계산하고 분석할 수 있으나, 주로 만곡부가 나타나는 사행하도의 편수위와 소류력, 유속을 고려하지 못한다. 따라서 만곡부의 수리 특성을 해석하기 위해서는 2차원의 수위, 유속의 급격한 흐름변화를 효과적으로 계산할 수 있는 홍수유출 모형이 필요한 실정이다. 본 연구에서는 강원도 삼척시에 위치한 오십천을 연구대상 지역으로 하여 2차원의 수리특성 분석이 가능한 Iber 모형을 적용하였다. 연구대상 하천을 5m 간격의 유한요소망으로 구성하고 DEM의 고도 값을 입력 하였으며, 하천정비기본계획에서 제시한 빈도별 홍수량을 적용하여 편수위, 소류력, 유속 등의 수리특성을 분석하였다. 그 결과 만곡부에서 최대 1.7m의 편수위가 발생해 여유고를 초과하는 결과가 나타났다. 유속과 소류력은 비례하는 경향을 나타내면서 만곡의 중앙보다는 외측에 집중되는 특징이 나타났다. 향후 하천의 만곡부에서 범람이 발생하면 하천 인근 지역의 피해를 예방하는 방안으로 2차원 모형이 도입되면 피해를 저감 할 수 있을 것으로 기대된다.
