Using germinal and somatic cell mutation assaying systems of Drosophila melanogaster, effects of Ginseng and Salvia miltiorrhiza extracts on the in vivo mutagenicity induced by N-methyl-N'-nitro-N-nitrosoguanidine(MNNG) were investigated. For these purpose, the attached-X method and the mwh/flr spot test system which are an X-linked lethal mutation and a somatic chromosome mutation assaying system, respectively, were used. In the induction of X-linked lethal mutations during the spermatogenesis, MNNG showed more actions in the sperm and spermatid stages, in which Ginseng and Salvia miltiorrhiza extracts had remarkable inhibitory effects than other stages. Ginseng and Salvia miltiorrhiza extracts reduced the mutagenicity by MNNG in the mwh/flr system, which reveal that they can inhibit gene mutation, deletion and mitotic chromosomal recombination. These results seem to suggest that Ginseng and Salvia miltiorrhiza extracts may exert their inhibitory effects to in vivo mutagenic and/or carcinogenic properties of DNA-damaging agents.

This study investigates consumers' purchasing behavior and perception of the low-carbon certificated agricultural product. To this end, we surveyed 1,000 consumers and the main findings are as follows. First, Even after six years of national certification, it is important to promote the low-carbon certification system due to insufficient awareness and purchase experience. Second, the certificated area is small at around 5% of the area of environment-friendly agricultural products and GAP certification, and certification is concentrated on fruit trees. Third, an appropriate level of high-priced strategy can be useful considering the cost of low-carbon certification, image management of low-carbon certificated agricultural products, and quality is the most important factor for consumers to consider when purchasing fresh agricultural products. Fourth, consumers recognized that the contribution of low carbon certification in reducing greenhouse gas emissions and preserving the environment was higher than that of environment-friendly agricultural products or GAP certification. Considering that, promotional activities linked to environment-friendly agricultural products and GAP certification may be effective when promoting low-carbon certification. Finally, the Ministry of Agriculture, Food and Rural Affairs is implementing a carbon point system linked to Green Card to revitalize low carbon certification, but 25.7% of consumers are aware of it, and 8.4% have little experience in issuing it.

Trauma care is evolving throughout the world to meet the demand resulting from rapidly increasing rates of mortality and morbidity related to external injuries. The State Major Trauma Service was designated to Royal Perth Hospital in 2004 to provide comprehensive care for trauma patients in Western Australia (WA), which is the largest state by area in the country. The State Major Trauma Unit, which was established in 2008, functions as a level I center and admits over 1,000 major trauma patients per year, making it the second busiest trauma center in Australia. The importance of recording data related to trauma was identified by the trauma service in WA to inspire higher standards of patient care and injury prevention. In 1994, the service established a trauma registry, which has undergone significant changes over the last two decades. The current State Trauma Registry is linked to a statewide database called the Data Linkage System. The linked data are available for policy development, quality assurance, and research. This article discusses the evolution of the trauma service and the registry database in the WA health system. The State Trauma Registry has enormous potential to contribute to research and quality improvement studies along with its ability to link with other databases.

This paper deals with conversion from the STL file to the Slice to the Slice cross-sectional information for Stereolithography. The STL file is widely used for Stereolithography, but it is very difficult to convert STL file into Slice file directly. Because it consists of an ordered list of triangular net without any topological information other than the orientation of each facet. So, The system is accomplished by data flow through several intermediate stages such as Reference. SL1. .SL2L. .SL3. and .SLC file. The data processing is performed in 5 steps: 1) Create a Reference file including common information. 2) Modify STL file within the effective range of SL machine. 3) Calculate a point of intersection between plane equation and line equation. 4) Sort z values in ascending order using quick sort algorithm. 5) Search the adjacent points and formulate a closed loop usingsingly linked linear list. The system is developed by using Borland C++ 3.1 compiler in the environment of Pentium PC, and verified to be satisfactory by making some prototypes of electric household appliances.

최근 인터넷이 가능한 컴퓨터뿐만 아니라 스마트TV, 스마트폰과 같은 장치를 통한 동영상 형태의 멀티미디어 소비가 증가함에 따라 단순히 시청만 하는 것이 아니라 동영상 콘텐츠 사용자들은 자신이 원하는 동영상 콘텐츠를 찾거나 동영상 콘텐츠에 등장하는 객체의 부가 정보를 브라우징 하고자 하는 요구가 증대되고 있다. 이러한 사용자의 요구를 충족시키기 위해서는 노동집약적인 어노테이션 작업이 불가피하다. 동영상 콘텐츠에 등장하는 객체에 직접 부가정보를 기술하는 키워드 기반 어노테이션 연구에서는 객체에 대한 관련 정보들을 어노테이션 데이터에 모두 포함시켜 대용량 데이터를 개별적으로 직접 관리해야 한다. 이러한 어노테이션 데이터를 이용하여 브라우징을 할 때, 어노테이션 데이터에 이미 포함 되어 있는 정보만 제한적으로 검색이 된다는 단점을 가지고 있다. 또한, 기존의 객체 기반 어노테이션에서는 어노테이션 작업량을 줄이기 위해 객체 검출 및 인식, 트래킹 등의 컴퓨터 비전 기술을 적용한 자동 어노테이션을 시도하고 있다. 그러나 다양한 종류의 객체를 모두 검출해내고 인식하여, 자동으로 어노테이션을 하기에는 현재까지의 기술로는 큰 어려움이 있다. 이러한 문제점들을 극복하고자 본 논문에서는 비디오 어노테이션 모듈과 브라우징 모듈로 구성되는 시스템을 제안한다. 시맨틱 데이터에 접근하기 위해 링크드 데이터를 이용하여 다수의 어노테이션을 수행하는 사용자들이 협업적으로 동영상 콘텐츠에 등장하는 객체에 대한 어노테이션을 수행 할 수 있도록 하는 어노테이션 모듈이다. 첫 번째는 어노테이션 서버에서 관리되는 어노테이션 데이터는 온톨로지 형태로 표현하여 다수의 사용자가 어노테이션 데이터를 쉽게 공유하고 확장 할 수 있도록 하였다. 특히 어노테이션 데이터는 링크드 데이터에 존재하는 객체의 URI와 동영상 콘텐츠에 등장하는 객체를 연결하기만 한다. 즉, 모든 관련 정보를 포함하고 있는 게 아니라 사용자의 요구가 있을 때, 해당 객체의 URI를 이용하여 링크드 데이터로부터 가져온다. 두 번째는 시청자들이 동영상 콘텐츠를 시청하는 중 관심 있는 객체에 대한 정보를 브라우징 하는 모듈이다. 이 모듈은 시청자의 간단한 상호작용을 통해 적절한 질의문을 자동으로 생성하고 관련 정보를 링크드 데이터로 부터 얻어 제공한다. 본 연구를 통해 시맨틱웹 환경에서 사용자의 상호작용을 통해 즉각적으로 관심 있는 객체의 부가적인 정보를 얻을 수 있도록 함으로써 향후 개선된 동영상 콘텐츠 서비스 환경이 구축 될 수 있기를 기대한다.

This study proposes schemes of GIS-based system development for integrated information management in water environment linked with Korean Reach File (KRF). For this purpose, precedent studies and systems of the U.S. were investigated and analyzed to induce optimal methodology for Korean circumstances. Thereafter, data linkage methods of KRF and Water Environment Information System (WEIS), system configuration plans, application development plans, and KRF improvement and maintenance plans were considered. For data linkage and system configuration, three methods were suggested: an overlay operation-based data linkage method, entering spatial addresses into the existing DB, and creating link information between KRF and the existing DB. The first method was predicted to be the most effective for system implementation, the second method is advantageous for search tasks, and the third method is advantageous for system security and maintenance. Various types of applications should be developed in the consideration of the types of the users and their usages. Moreover, there is a need for further research on regular renewal of KRF, standard development, expansion of construction areas, etc. Based on the present results, research on actual system design and development also should be conducted for supporting Total Maximum Daily Loads (TMDLs).
