Aquaculture has historically delivered marine products because the country is surrounded by ocean on three sides. Surveys on production have been conducted recently to systematically manage aquaculture facilities. Based on survey results, pricing controls on marine products has been implemented to stabilize local fishery resources and to ensure minimum income for fishermen. Such surveys on aquaculture facilities depend on manual digitization of aerial photographs each year. These surveys that incorporate manual digitization using high-resolution aerial photographs can accurately evaluate aquaculture with the knowledge of experts, who are aware of each aquaculture facility's characteristics and deployment of those facilities. However, using aerial photographs has monetary and time limitations for monitoring aquaculture resources with different life cycles, and also requires a number of experts. Therefore, in this study, we investigated an automatic prototype system for detecting boundary information and monitoring aquaculture facilities based on satellite images. KOMPSAT-3 (13 Scene), a local high-resolution satellite provided the satellite imagery collected between October and April, a time period in which many aquaculture facilities were operating. The ANN classification method was used for automatic detecting such as cage, longline and buoy type. Furthermore, shape files were generated using a digitizing image processing method that incorporates polygon generation techniques. In this study, our newly developed prototype method detected aquaculture facilities at a rate of 93%. The suggested method overcomes the limits of existing monitoring method using aerial photographs, but also assists experts in detecting aquaculture facilities. Aquaculture facility detection systems must be developed in the future through application of image processing techniques and classification of aquaculture facilities. Such systems will assist in related decision-making through aquaculture facility monitoring.

4차 산업혁명시대를 맞이해서 세계 각국이 경제 활성화를 위하여 창업을 장려하고 있는 추세이다. 글로벌 관점에서 재정위기가 있었던 지난 2008년 이후 여러 국가들의 산업전반에서 위기감이 고조되어 경제 활성화를 위하여 창업을 장려하는 사회적 공감대를 형성하는 등 세계 각국은 청년창업을 통한 경제성장에 주력하고 있다. 우리나라도 현재 세계적인 흐름에 맞추어 정부와 지방자치단체가 최우선의 정책과제로 청년층의 창업을 지원하는 등 창업 활성화 노력을 경주하고 있다. 한국경제의 활성화 및 청년실업의 문제를 해결하고 더 나아가 4차 산업혁명에 대비한 새로운 신성장 동력을 발굴하기 위하여 정부와 지방자치단체는 창업을 새로운 돌파구로 삼아 청년층의 창업을 지원하는 등 다양한 지원정책을 시행하고 있지만 상당수의 창업 지원정책들은 지역의 창업 실태를 면밀하게 파악하지 않은 상태에서 일반적인 창업 지원방안들이 수립, 집행되곤 하는 것이 현실로 가시적인 효과는 당장 나타나지 않고 있다. 특히 청년창업은 퇴직 이후의 생계형 창업과 달리 신성장 동력분야 및 기술·지식 집약적인 분야에 대한 창업으로 구성되는 경우가 많아 국가 산업적인 측면에서도 그 중요성은 매우 크다고 할 수 있다. 정부와 대학 및 학생 등은 ICT 중심의 창업 생태계를 구축하는 등 새로운 시도를 모색하여 창업 활성화를 통한 경제 활성화를 유도하기 위하여 일자리 창출과 신산업 육성에 다양한 정책을 추진하고 있다. 이에 본 연구는 청년창업가가 창업성과를 높이기 위한 청년창업가 특성들이 창업성과에 미치는 영향을 살펴보고 네트워크 활동이 청년창업가 특성과 창업성과에서 매개역할을 하는지에 대해 실증분석 하고자 한다. 본 연구를 통해 향후 청년창업가들이 창업성과를 내기 위해 고려해야 하는 여러 요인 중 우선적으로 확보하거나 수행해야 하는 요인을 파악하여 자원을 효율적이고 효과적으로 사용할 수 있도록 기여하는 것을 목적으로 한다.

In recent years, as remotly-sensed image processing technologies have been improved and spread widely in the application areas, many new requirements for the image processing technologies have arisen. However, it is difficult and costly to access remotely-sensed image processing systems. Moreover, these systems have thier own processing facilities which are not easily accessible for general users. In this paper, those problems are challenged by adopting Internet as a universal information network for accessing remotly-sensed image DBMS and by allowing users to work remotely on the image processing. A remotly-sensed image processing system which can be accessed via Internet was designed and implemented. This system can be used to manipulate images over remote DBMS. The Illustra object-oriented relational DBMS with CGI(Common Gateway Interface) web interface was used in this project. The client consists of a WWW(World Wide Web) Netscap$e^{TM}$ browser, and the server consists of HTTPD(Web daemon), Illustra DBMS and Java modules in order to process the image being displayed. The developed system was tested on LAN environment and the service response time met the requirements.

Energy saving is becoming more and more important issue due to lack of resources and limited nature. However, There is a lack of learning status on energy saving in the school field. In particular, in elementary education on energy saving was not linked to practice, and the educational effect was insufficient. Although various kinds of learning tools are utilized, many successful cases of energy saving game strategy are introduced in overseas industry field, and game design is proposed so that energy related education can be played through games. Because energy conservation can not be effective without practice, learning using games as a tool is expected to be more effective than learning based on knowledge transfer in the classroom. We propose a defense game for energy conservation education by using the mission elements, score acquisition element, time limit element, and character element which are the interesting elements of the game designed in the previous research.

The purpose of this study is to increase access to information on old maps and to discuss efficient ways to utilize old maps, such as providing services and information using old maps. To this end, the information search system of domestic institutions that provide old map information was investigated, and methods of searching for old map data and accessing information were searched on the website. In addition, the current status of the collection of old maps in domestic libraries and museums was analyzed by referring to the homepage, book, research book, and publication of each institution. As a result of the analysis, about 2,200 old maps were housed in 76 institutions, including national, public, and university libraries and museums nationwide. Each institution in the collection of old maps was carrying out publication business, such as publication of English manuscripts, exhibitions and books, publication of research document edits such as lists and summaries. However, reading and using of original documents are limited due to the rare nature of old maps and the data characteristics of the only one. In order to effectively utilize old maps, first, it is necessary to improve access to old map information services and expand academic information services. Second, it is proposed to use old maps as data for archival construction that reflects the identity of the region. Third, it is necessary to cultivate professional manpower who selects and provides information based on knowledge of old map data and humanities literacy.

As the effective use and strong protection of an organization's information resources are recognized as a condition for the growth of an organization, they are increasing technological and policy investments in IS(information security). However, information exposure can occur from external invasions such as hacking and incidents related to misuse and abuse by insiders. This study proposes a mechanism that considers the organizational environment and individual characteristics from the viewpoint of promoting employees' IS participation activities. In other words, the study presents the complex effects of organizational environmental factors (ethical leadership, IS collaborative communication) and personal factors (person-organization fit) on organization trust and IS voice behavior. We surveyed office workers who asked for IS-related business activities and tested hypotheses using 422 samples. As a result, ethical leadership influenced organization trust through collaborative communication, and organization trust strengthened IS voice behavior by having an interaction effect with person-organization fit. This study suggests direction for establishing an organizational environment for promoting IS-related activities by office workers, so it provides practical implications for organizations with goals related to internal information exposure control.

The speed of change on information technology is very fast, so it demands a continuous competency development in IT human resource management. If the competency development for IT personnel can not keep up with the change of Technology, IT personnel cannot accomplish their IT job under new IT environment. For this reason, many companies have tried to manage IT organization separately and IT job system on the technology basis. Although the training of IT is different from that of other field in feature, few studies about IT human resources system have been conduced. Therefore this study focuses on the training system of IT personnel and suggests the framework for institutionalizing the operation policy and the individual process through a case study methodology. This paper chose one company as a case study which implemented the training system of IT personnel recently, and the proposed framework based on the literature review from this study applied to a company. The study shows that IT job system needs to be reasonably established, job descriptions should be appropriate to IT job, and there exist two training paths according to two career path - Specialist and Generalist. For the purpose of high performance in IT division, the training manager should understand IT job system, the people who need training, and keep an eye on the IT trends and new IT skills.
