While fishery has been continuously suffering from deteriorating economic feasibility, the amount of the deposited marine litter has been increasing due to an increased number of marine leisure tourists which are caused by an improved quality of life and five-day work week. In addition, the fishery area has been reduced by the reclamation projects and it is being destroyed by marine pollution with a variety of contaminants coming from land and sea. To protect and improve fisheries in these poor conditions, Korean governments have implemented the submerged marine litter collection projects. However, previous research results on the marine environment and resources indicate that it requires a lot of time investment to achieve tangible results of such improvement. The 300 billion won marine environment and resource investigation project has been executed since July 2004 by Korean governments, which demands strategic approaches to obtain more effective and satisfactory results before the project expires in 2013. Ocean environment research institutes and governments need to cooperate each other to gain efficient and reasonable achievement by identifying and linking related projects. This study suggests that the marine environment and resources investigation projects should run parallel with the submerged marine litter collection projects on mutually agreed research items in the identical area of the ocean to obtain cost-effective improvement of marine environment and fishery conditions.

The main purpose of this paper is to apply Zone 30 system which is being experimented in advanced country for the solution of controlling the residential street's speed to our country with the consideration of the real condition of our street and traffic and to run this system as an example to analyze the effect and at the same time, analyze the problem and get appropriate preparation for this system to be widespread. The area to run this model project is Goyang City Ilsan-Gu.($0.65km^2$) which is close with the commercial area reflecting the opinion of experts and an on-site verification by the National Police Agency T/F and is having a heavy pedestrian traffic and the risk of pedestrian accident. Firstly we defined residential street and residential street area to review the system and devided the residential street type to establish a plan of operation. Afterwards, we thoroughly examined the model project area and analyzed the problem and solution. We finally completed establishing a facilities by conference with a local autonomous entity with the improvement of facility's sketch at the analysis of the model project area. The result of effects analysis which we devided after and before of establishment is that vehicle speed be reduced 5~15km/h, and traffic accidents has decreased by 24 percent.

Purpose: The purpose of this study is to suggest a smart city strategy through smart growth considering the human, social and cultural meaning. It seeks opportunities to develop the cities that has not grown by integrating the ICT, a new growth tool for smart cities, into the spatial and physical renewal project. Method: Analyzing policy and strategy of smart living lab and digital cultural contents on the smart growth process under the experience in Amsterdam and Paris. Results: Smart city is expected to be reflected not only the technical aspects but the social characteristics of the city in order to enhance the living environment of the citizens by embracing diverse viewpoints throughout the city. It examines the smart growth plan in the improvement of the living conditions of the citizens. Conclusion: Planning smart city is to discover the smart city adaptability that can enhance the capability of cities to improve the life condition and quality of citizens by applying the core strategies and specialized programs with community service and urban marketing, which are emerging as smart cities based on ICT technologies.

Public libraries have been well adapted for the changes in lifestyle and socio-cultural environments brought by the rapid advancement of information technology, the development of mass communities, and the increase in leisure activities. Government and local communities demand public libraries to take in charge of providing lifelong education for the Public. Many Public libraries have worked as a center for life-long education, while carrying out various functions and services in close relation with the life of community members. Public libraries are in a very poor condition, lacking the facilities, professional workforce, budgets, and so on, which are sufficient to strengthen their role as a center for life-long education. In this study, the roles of public libraries in developing life-long education are examined as follows : First, the concepts and directions of life-long education are discussed : second, the roles of public libraries in facilitating life-long education are examined and third, the categories of life-long education programs of public libraries are suggested.

This study aims to derive the main factors for predicting student departure of university freshmen and provide the basis for establishing policies to prevent student departure at the institutional level. For this purpose, a random forest model is developed with the data observed for 2 years at a four-year private university in Seoul. In the prediction model, 6 variables of school adjustment factors and 12 variables of institution satisfaction factors are applied. The top 6 variables presenting the highest MDA turn out to be emotional stability, financial conditions, assurance in the choice of major, satisfaction with the choice of university, educational method(systematic teaching method), educational method(effectiveness of major education). Based on the results of this study, it is suggested the necessity of institutional design supporting freshmen to adapt to university life and stably continue their studies.

The purpose of this study is to analyze the spatial structure of laboring classes in Manchester in the 19th century. Manchester had districts where laboring classes lived in destitution. Elizabeth Gaskell's Mary Barton demonstrates the miserable state of laboring classes by depicting their small, dirty living residential spaces. Engels's The Condition of the Working Class in England analyzes the laboring classes in industrial areas in England, especially Manchester. The laboring classes' districts formed in a set pattern were separated from the area for bourgeois. It lied in the old district near commercial areas, while upper classes were outside areas. It was the dominant ideology that drove the transformation of Manchester as an industrial city characterized by separation.

인터넷의 발전은 우리 교육계에 많은 변화를 가져오고 있다. 초고속 인터넷 서비스의 등장과 함께 인터넷 대역폭이 커지면서 작은 용량의 파일전송 위주에서 음악, 영상, 애니메이션 등의 대용량 서비스가 많아지는 추세에 따라 인터넷 홈페이지도 동영상을 위주로 서비스하는 곳이 급증하고 있다. 초등학교에서도 학교소개, 학교행사, 학생활동을 동영상으로 제공하여 활용도가 낮은 학교 홈페이지의 활용도를 높이고 학생들이 기획, 제작, 편집에 직접 참여하여 적성과 흥미를 키우며 생활 여건 때문에 학교행사에 참여하지 못하는 학부모들의 참여를 이끌어 낼 수 있는 학교 인터넷방송국을 구축을 통해 교육적 효과를 얻기 위하여 초등학교 인터넷 방송국 구축방안을 제시하였다.

경제 여건의 향상 및 생활양식의 변화로 최근 우리나라에서도 당뇨병 환자가 늘어남에 따라 당뇨병의 예측 및 치료가 중요한 관심사가 되고 있다. 본 논문은 1993년과 1995년 두 차례에 걸쳐 경기도 연천 지역 주민들의 여러 가지 신체 지수 등을 조사한 데이터를 대상으로, 1차 년도의 데이터로부터 동일한 환자가 2차 년도에 정상상태를 유지하는지 흑은 당뇨병으로 진행이 되는지를 예측하는 문제를 다룬다. 혈당량, 허리둘레 등의 수치가 당뇨병의 발병에 영향을 끼치는 것은 알려진 사실이므로, 현재의 데이터로부터 앞으로의 발병 가능성을 예측하는 것이 가능하며, 이는 환자에게 보다 정확한 정보를 알려줄 수 있으므로 의미가 있는 일이다. 예측을 위해 본 논문에서는 분류기를 사용하며, 예측율을 높이기 위해 여러 분류기를 BKS로 결합하였다. BKS (behavior knowledge space) 결합 방법은 분류기간의 독립 가정이 필요 없으며, 데이터 크기가 크고 전형적인 경우에 좋은 결과를 낼 수 있는 방법이다. BKS 결합 방법을 통해 실험을 해본 결과 단일 분류기로 실험을 한 결과보다 향상된 성능을 얻을 수 있었으며, 투표 결합 방법과 비교하여 더 좋은 성능을 보였다.

인터넷이 보편화되어 이젠 일상의 한 부분으로 자리 잡아 가고 있다. 단순히 웹 서핑이 아닌 보다 효율적이고 건설적인 인터넷의 활용은 사회 전 분야에서 활발히 전개되고 있다. 뿐만 아니라 멀티미디어의 기술 발달은 인터넷의 보편화와 더불어 교육방면에서 새로운 국면을 맞고 있다. 본 연구는 정보화에 소외된 어업인의 정보화 격차의 해소와 생활터전에서 여건상 수산기술관리소에서 교육을 받지 못한 수산신기술을 웹 환경에서 해소함으로써 교육에 참석하기 위해 시간, 교통비등 부대비용을 줄이고, 또한 다양한 멀티미디어 교재를 통해 어업인들이 반복학습의 장점을 살려 수산신지식기술을 보급하고자 시스템을 구축하여 멀티미디어 교재를 개발함에 있다.

생활환경이 새로운 패러다임으로 변해가고 있다. 유비쿼터스 환경을 앞당기기 위하여 산업체 전반에 걸쳐 변화를 거듭하고 연구가 지속되고 있다. 유비궈터스 환경은 농업 분야에도 적용되어 농산물의 재배와 수확에 이르기까지 전반적인 형태를 변화 시키고 있다. 재배 시설을 원격지에서 제어함으로써 적절한 재배환경을 지원할 수 있도록 하여 환경변화 관리를 효율적으로 할 수 있으며, 사용자의 성향에 맞는 재배 환경 여건을 지능적으로 판단하고 제어 할 수 있는 시스템이 요구된다. 본 논문에서는 다양한 환경 즉, 온도, 습도, $CO_{2}$, 조도 등의 변화를 센서네트워크를 통하여 감지하고, 퍼지시스템을 통하여 환경변화를 추론하여 환기시설을 적절하게 제어할 수 있는 시스템과 알고리즘을 제안한다.
