This paper proposes a new ABTC (Adaptive Block Truncation Coding) algorithm which improves the BTC algorithm for image data compression. A new adaptive block truncation coding which adopts a selective coding scheme depending on the local characteristics of an image has been described. The characteristics of the ABTC algorithm can be summarized as high compression ratio and the algorithm simplicity. Using this algorithm, color images can be coded at a variable bit rate from 1.0 (bit/pel) to 2.56 (bit/pel) and high compression rate (1.3-105 bit/pel) can be achieved without conspicuous image degradation compared with original images.

Although the native local data is being deemed important in the age where historical records are regarded as important, currently it is hard to find out detailed actual state of local data, because it is now being collected and managed by many institutions and individuals. This study is aimed at surveying the current state of management of native local data possessed by local cultural center, one of institutions that produce and manage local data, and suggesting a desired alternative idea of cultural center for management of native local data, through the problems found by the research. As the result, the current state of data management of the local cultural center are as follows: First, local data management in the local cultural center as the problem in poor surroundings and a financial question get local data-related education make systematic data collection and management unavailable. Second, local data depends on the extent of its awareness of it. each and every cultural center shows a significant deviation in the extent of execution of local data-related project. Third, even though the publication business of the cultural center is being lively executed, it attaches importance to the history of local authority rather than to the residents' life, and it should not be supplemented in applying it to education and production of cultural contents.

In December 2017, the Moon Jae-in administration announced a major policy shift away from nuclear and coal, committing itself to the vision of creating a society where renewable sources account for 20% of its electricity generation by 2030. This energy transition involves not just a technical transition from conventional energy sources to renewable energy but also active participation of multiple stakeholders in the energy governance. While energy policy making has long been dominated by the central government in Korea with the aim of managing the supply for rapid industrialization and economic growth, the Moon administration aims to diffuse the central government's authority across various actors in society. Among those actors, this study focuses on the roles that local governments play in energy transition. Despite deepening local autonomy since 1995, Korean local governments have remained policy targets or recipients in the energy policy domain. This article discusses how such a traditional role has evolved under the new administration's energy transition policy and examines what challenges and limitations local governments face in creating a more decentralized energy governance system.

Traffic Accident Merging Index(TAMI) is developed for TMACS(Traffic Safety Information Management Complex System). TAMI is calculated by combining 'Severity Index' and 'Frequency'. This paper suggest the accurate TAMI prediction model by time series forecasting. Preventing the traffic accident by accurately predicting it in advance can greatly improve road traffic safety. Searches the model which minimizes the error of 230 local self-governing groups. TAMI of 2007~2009 years data predicts TAMI of 2010. And TAMI of 2010 compares an actual index and a prediction index. And the error is minimized the constant where selects. Exponential Smoothing model was selected. And smoothing constant was decided with 0.59. TAMI Forecasting model provides traffic next year safety information of the local government.

A nationwide questionnaire survey was conducted to investigate the actual conditions of local authorities in operating and maintaining sewerage systems especially for urban flooding. The questionnaire includes the incidences of flooding since 1980, the existence of any guidance for preventing flood damage and the design frequency currently used for sewers in each local authority. Among 160 local authorities responded to the survey, 95(59.3%) has experienced flooding more than once since 1980 while only 36(37.9%) of the 95 has prepared operation/maintenance guidelines for flooding. Most of the respondents have applied the 10 year design frequency for sewer design and 57(35.6%) of them agreed to adjust the 10 year design frequency regulation.

This year the Ministry of Environment(MOE) made a fifth amendment to the Sewerage Act, which was enacted in August 1966. The first objective of this amendment is to introduce small public sewerage system that is designed to treat wastewater produced in rural areas. Before small public sewerage system was introduced to the Act through this amendment, only urban areas were covered by public sewerage system. Because small sewerage system was introduced, wastewater generated in urban areas as well as rural areas can now be treated by public sewage treatment plants. In addition to this, some authorities on sewerage affairs were moved from the MOE to local governments by this amendment in order to enhance the power and responsibility of local governments in relation to sewerage affairs. Also, this amendment enabled local governments to entrust the authority to establish and manage sewage treatment plants to private companies, and enabled the MOE to organize an advisory committee on sewerage to review economic and technical aspects ofsewage treatment plants. This amendment went into effect September 8, 1997.

A major effect of electronic commerce on the Internet is that it reduces transaction costs and creates an efficient market. Thus, an information strategy for developing of regional economy must be changed toward 21st century of electronic commerce era. In this paper, we present an information strategy for activating the electronic commerce of regional small and medium-sized business organizations. The paper stresses creation of a network organization comprising local government, regional business organizations, universities, research institutes, and citizens' coalitions as groups of organizational actors. Necessary conditions of a successful network organization in electronic commerce are to build the public key infrastructure for developing the trust of transactions among partners, and to create an information center to manage a web of partners. In the network organization, the information center must play critical roles as a creator of value and the certification authority in order to issue and manage participants' electronic certificates.

China power market is fast changing. The strong economic growth does make BOT power projects to be one of the focuses for investment in China due to the huge demand for energy by the Chinese government. Since late 80's,various power projects BOT studies have been carried out but appear too fragmented which fail to linked the BOT studies to the most recent government policies' changes or market movement. This study has carried out analysis on the recent changes in China power industry reform and local government authority empowerment. The impact of those changes to BOT investment has been identified and recommendations have been made on the new opportunities and new strategies especially from the Singapore's investors' point of view. A case study on BOT hydropower plant has been presented which could be a suitable model for Singapore investors.

This paper aims to link the development strategy of a local government(Guri-si, Kyunggi-do) to a spatial decision support system that is in the early stages of implementation and testing. Spatial Decision for a local governmental authority typically involves multiple stakeholders. To any specific regional problem, stakeholders often have various levels of knowledge and experiences about it, that yield conflicting views. In this point of view, the enhanced access to information can bring the decision process to solve the problem throughout more public participation. Recently, Urban development study was required to improve the decision making of public participation form. This study aim to investigate an analysis local government of Guri-si, can be supported as the suggestion of decision making system. Guri-si has been argued that it would improve citizen's life quality intent theme 'by historical tourism in general dimension' promote region identity, environment friendly and transportational strength, by reflecting various plan of urban development and it executed strategy. There are increasing interest in citizen participation and practical using of policy decision making to respond to uncertain environment and systematic exploration of local government. Focused on the contents of public participation decision making, it is important to investigate how to analysis urban development strategy and geographic information relationship for useful. The paper concludes with a discussion of current issues encountered during development and implementation of spatial decision making(or support) system for the local administrative authority.

According to the change in media environment, a support plan for local broadcast has been required. In terms of legal and institutional support for the development of local broadcast, the enactment of special Act for local broadcast has become a breakthrough. In this point of view, we analyzed the performance and the limitation of the special Act. As a literature research, analyzing the literature and related-ordinances, we have sought legal and institutional support plans for the local broadcast. As a result, with the Local Broadcast Development Council being in charge of legislative right and responsibility, a plan to empower them to have legal and institutional authority should be drawn; another plan to secure independence in operating a fund and to promote the capability to produce local broadcast programs and the distribution system should be drawn; the other elaborate plan for the locality index that assesses the locality is required. Local broadcast should be on a way to secure not only public interest and concern but locality and diversity; legal and institutional plans should be sought.
