Of the countries where Korea has advanced for overseas afforestation investments, Indonesia might be the most important country. As the end of 2010, nine Korean companies have been implementing afforestation projects in Indonesia, covering a total area of one hundred and fifty thousand hectares roughly. Following the Memorandum Of Understanding (MOU) on afforestation investment covering five hundred thousand hectares (A/R CDM / industrial afforestation) signed between Korea and Indonesia, the two countries concluded in 2009 an additional MOU covering two hundred thousand hectares for biomass afforestation, thus securing a total afforestation area of seven hundred thousand hectares. Further it was guaranteed that afforestation license would have validity for maximum 95 years, which laid the foundation for long-term stable investments for afforestation projects. Forest law of Indonesia consists of Presidential decree and Governmental decree as superior regulations and Minister's decree as subordinate regulations, being made up of total 17 chapters. Forestry Minister's decree was amended at end of last year, as regards license for exploitation of timber and forestry products in afforestation area. In the past, such license to develop and use timber and forestry products had been granted under Forestry Minister's decree No. P 11 / Menhut-II / 2008. After the amendment in 2010, however, the ground was shifted to Forestry Minister's decree No. P 50 / Menhut-II / 2010, trimming the procedure to obtain afforestation license into a little simplified one.

In spite of advanced navigational devices and reinforced mandatory standards of officers' education, the number of ship's accidents are increasing. The accidents caused by minor license officers are more than the number of accidents caused by superior license officers. There are many cases of collisions in the past 5 years released on Marine Accidents Inquiry Agency. Especially, officer's negligence from the consequences of the neglect of any precaution which may be required by the ordinary practice of seamen is the main reason behind ship's collisions. For reducing ship's accidents caused by human error, this paper suggests to develop effective training program using analysis date of domestic and foreign education system as a reference.

Recently, deep learning networks with high performance for object recognition are emerging. In the case of object recognition using deep learning, it is important to build a training data set to improve performance. To build a data set, we need to collect and label the images. This process requires a lot of time and manpower. For this reason, open data sets are used. However, there are objects that do not have large open data sets. One of them is data required for license plate detection and recognition. Therefore, in this paper, we propose an artificial license plate generator system that can create large data sets by minimizing images. In addition, the detection rate according to the artificial license plate arrangement structure was analyzed. As a result of the analysis, the best layout structure was FVC_III and B, and the most suitable network was D2Det. Although the artificial data set performance was 2-3% lower than that of the actual data set, the time to build the artificial data was about 11 times faster than the time to build the actual data set, proving that it is a time-efficient data set building system.

This paper propose a method to enhance the performance of digital contents streaming services with the improve DRM system by maximizing the distribute computing performance and minimizing the overheads of security threatens caused by increasing users and sharing contents in P2P environments. By improving authentication protocols and license protocols to perform decryption and execution simultaneously by only download of the license, streaming services are more enhanced rather than existing DRM systems. For evaluate the performance, this paper compared execution time of existing DRM systems which decrypt the encrypted data file before execute with improved DRM system which execute and decrypt the encrypted data file simultaneously. In experiment, improved DRM system can maintain steady bandwidth and reduce the execution time in compare to existing DRM systems.

This study deals with the evolutional history of the holding and utilization of fisheries resources in Korea. Fisheries resources have the basic characteristics of the density dependent self-regulating renewable and common property resources, Irrational utilization of fisheries resources is mainly due to the unlimited access to the resources. The holding and utilization of fisheries resources in Koryo era was opened to everyone. But it was nationalized in the early Yi Dynasty. The purpose of its nationalization was to provent the paticular powered-man with their monoplized holding and to levy fisheries tax. Eoeop-peop, the first modern fisheries law in Korea, was enacted as a part of the invasion policy of Japan in 1908. With the japanese annexation of Korea in 1910, the Japanese Government established a new institutional system of fisheries as a part of an overall reformation of the institutional for an implementation of the colonial policy. It was very the new enacted Fisheries Law (Gyogyorei). Also the Government enacted compulsorily another new Fisheries Law (Chosen Gyogyorei) with its adjunct laws and regulations revise the institutional system of fisheries on May 1, 1930. After Eoeop-peop enactment, the fisheries resources in Korea could be used only under the license, permission, and statement. After Korea was from Japan in 1945, Korea Government at last enacted the new fisheries law (Susaneop-peop) in 1953. The goal of Susaneop-peop was to achive the general usage and protection of the fisheries resources, and to attain the development and democratization of the fishery in Korea. This law was amended 13 times until 1990. The license fishery have a legal right on the fishery, called a fishery rigt. This right means a right of exclusive occupation and utilization of a unit of the inshore fishing grounds. The main evolutional issues of license fishery are as the following : 1) the foundation of the exclusive usable fishery right(1911, Gyogyorei), 2) the deletion of the settled U9space lift net and settled space sein net fishery, and the expansion of the cooperative fishery-No.1, 2, and 3 type cooperative fishery-(3rd amendment, 1963), 3) the deletion of the No.2 and 3 type cooperative fishery, and the separation of the culturing fishery in No.1 and 2 type culturing fishery (13th amendment, 1990). The effective period of the license fishery was amended as the following : 1) 1908(Eoeop-peop) : within 10 years, renovation system, 2) 1929(Chosen Gyogyorei) : within 10 years, unlimited extension system, 3) 1971. 7th amendment : 10 years, renovation system, 4) 1972. 8th amendment : 10 years, only 1 extension system, 5) 1975. 9th amendment : 5-10 years, only 1 extension system, 6) 1990.13th amendment : 10 years, within 10 years of total extensional years. The priority order of the fishery license was established in 1953 (Susaneop-peop). The amendment of it is as follows : 1) 1953. enactment \circled1 the fishing grounds that the fishery right is extablished 1st order : the existing fishery right man, unlimited renovation 2nd order : the corporate that the regional fisherfolk organized 3rd order : the rest experienced fishermen \circled2 new fishing grounds 1st order : the corporate that the regional fisherfolk organized 2nd order : the rest experienced fishermen 2) 1971. 9th amendment \circled1 the fishing grounds that the fishery right is established 1st order : the existing fishery right man, unlimited renovation 2nd order : the Eochongye that the regional fisherfolk organized 3rd order : the regional fishery cooperative that the regional fisherfolk organized 4th order : the rest experienced fishermen \circled2 new fishing grounds 1st order : the Eochongye that the regional fisherfolk organized 2nd order : the regional fishery cooperative that the regional fisherfolk organized 3rd order : the rest experienced fishermen 3) 1981. 10th amendment \circled1 the inside of No.1 type cooperative fishing grounds 1st order : the Eochongye that the regional fisherfolk organized 2nd order : the regional fishery cooperative that the regional fisherfolk organized 3rd orer : the rest experienced fishermen 4) 1990. 13th amendment \circled1 No.1 type cultural fishery 1st order : the Eochongye that the regional fisherfolk organized 2nd order : the regional fishery cooperative that the regional fisherfolk organized 3rd order : the rest experienced fishermen \circled2 No.2 type cultural and settle fisher : general priority order The effective period of the permission fishery was amended 6 timed. First, it was within 5 years and renovation system (Eoeop-peop). Now it is 5 years and renovation system. The effective period of the statement fishery was amended 4 times. First, it was within 5 years, and then was amended within 3 years(Chonsen Gyogyorei). Now it is 5 years.

DRM(Digital Rights Management) and CAS(Conditional Access System) have been used for preventing the illegal use of contents. These schemes had caused inconvenience to even legal users about contents, however, as restricting movement and playing. As going increment of requirement about the flexible usage of the content in digital home recently, we propose a new method that can easily share and use the DRM applied contents using domain concept. As setting the domain license in the extent of license that the existing DRM has been provided, the proposed system can cut off the illegal use and distribution of the content.

The Proposal of this paper is to draw up solution about fishing disputes in Korea coastal waters. Small fishing vessels under 8 metric tons which is regulated by the provincial governors, must operate within provincial boundary on the sea as in fishery policy of Korea. on this, I think that the present situations of fishing disputes have related to the fishing license system. Problem of this kind, Before 1970's, fishing disputes rarely took place, and it, if any, did not bring any social conflicts or disputes. Since 1980's, some of fishing disputes have been reported within fisheries society Recently, The disputes have been increasing to become social conflicts between local people concerned and have evoked an argument on whether the provincial boundary on the sea exists. If such disputes continues to increases or remains unsolved, they will bring a tremendous social cost such as an accelerated decrease in fish resources, degradation of fishing grounds, disorder in fishing, destruction of fisheries culture and so on. The reasons for the growing disputes can be specified as fellows : the degradation of fish resources, the present fishing license system which inherently causes competitions in fish catching, irrational ceiling system of fishing vessels, legal problem on existing boundary between neighbouring two provinces, the functional problem of national or regional fishery coordination committee which has been established to coordinate general fishing disputes. This study has also dealt with Japan's experiences in fishing disputes which has the history of more than a hundred years and its coordinating mechanism. In the discussion section, some possible solutions have been briefly touched fer further study.

The web-based technology allows anybody who has access to the Internet to get all kinds of information from the World Wide Web. It brings about issues regarding intellectual property and copyright threats. After content is downloaded, no further protection is provided on the content that has been accessed. DRM (Digital Right Management) technologies came out to ensure the protection of copyrighted content and information. In this paper, we propose architecture of license-based digital rights management system for protection of contents and principles' rights such as contents creators, providers, distributors, and uses in contents distribution value-chain over Internet. This system makes on-line processing of all value-chain from creator to purchaser possible, compared with existing DRM products only supporting only limited distribution between distributor and purchaser.

Advanced nations such as US and Europe have recognized the importance of the aircraft airworthiness and have been operating airworthiness certification system by their government since long time ago. In Korea, airworthiness certification personnel education program has been proceeding, since certification system of military aircraft airworthiness has been legislated. On this study, education course, education content for each course, education operating method and license management related to airworthiness certification personnel education and drew out adequate plan for domestic circumstance through studying aviation advanced nations cases. The proposed education course is divided into basic course, professional course and retraining course, considering its level of education and operation of education course has been recommended to a professional education institute designated by korea government and proposed to acquire authorized certificate for those who completed the education course. We hope to improve the method proposed as a result of the study such as education content, operating program, license management systematically and efficiently as years go by to develop into leading nation for airworthiness certification education and increase the benefit and confidence of nation.

In this thesis, first, we propose I-frame encryption techniques of video data for video data itself encryption and propose license agent that processing user's certification and decryption in client system automatically when user execute encrypted video data in system server. License agent runs user's certification, encryption and decryption of video data based on PID(Public Key Infrastructure) using shared key-pool when execute of video data. Also, compose duplex buffer control and propose real time decryption method using efficient buffer scheduling to reduce much playing delay times that happen processing decryption when execute of videoa data of high-capacity.
