  • The purpose of this paper is to provide a better understanding of the unprecedented reform movement of geographic education in the United States since 1980 and extract some implications from this movement for geographic education in Korea. For the purpose, the history to this movement was reviewed through following three stages. In the first stage(1980~1984: form :HSGP" to :"Guideline"), the voluntary improvement movement appeared at California and the orgni-zational movement began in 1982 such as the Committee on Geography and International Knowledge. The national educational refrom imperatives, presented at "A Nation at Risk", and "Back to Basics" movement provided good opportunities to resurrect geography as a basic subject. For next real resurrection movement, the very important document "Guidelines for Geographic Education" was published at 1984. In the second stage(1985~1989: from "Guide-lines" to "Public"), the "Guideline" gave power-full motives and foci for reconstructiong the contents of geography, especially by the five fundamental themes(Location, Place, Relation-ships within Places, Movement, and Region). Also GENIP as the symbol of unity of all four major geography organization(AAG, NCGE, NGS, AGS) contributed to expanding and stren-gthening geography education. Also Geography Educagtion Program of NGS was a smart and well organized program to improve geographic education through it's a five strategies: Grass-roots organization(Alliances), Teacher education, Pu-blic awareness, Educational materials develo-pment, Targeted outreach to education decision-makers. In the late 1980s, the last focus of movement was the Public awareness and Edua-ction decision-making. In the third stage(1990-present: from "Public" to "Core Subject"), the initiative pendulum swung from geography organization to nation curricu-lum. In this National Curriculum, Geography was approved as a "Core Subject" and The 1994 National Geography Assessment Framework was constructed to assess the outcome of student's education in geography in grades, 4,8, and 12. Some Implications extracted from the process and contents of renaissance movement of geogr-aphic education in the Uinted States since 1980 are as follows. First, It shows the importance of the unity and target assignment among the geography organization. Second, interactive relationship between the academic geography and school geography develops each other. Third, teacher education, including pre-service education, including pre-service education and in-service education, is a key element to improve the quality of geography. And teacher organization is a good clearing house to exchange information for good geography. Forth, the positive and active response to changes in socketies such as globalism and inter-nationalizing, national education policy, and the trend of pedagogy is needed to rejuvenate geo-graphic education. Above all, we need to establish a well organized and powerfull program, sophisticated activities strategies, and long-term implementa-tion plan if we want more and better school geography.

  • The development and distribution rate of smartphones have progressed so rapidly that it is safe for the entire nation to use them in the smart age, and the use of smartphones has become an essential medium for the use of domestic media content, and many people are using various contents regardless of gender, age, or region. Recently, various media outlets have been consuming video content for online learning, indicating that learners utilize video content online for learning. In the previous research, satisfaction studies were conducted according to the type of content, and the improvement plan was necessary because no research was conducted on how to evaluate the learning content itself and provide it to learners. In this paper, we would like to propose a system through evaluation and review of learning content itself as a way to improve the way of providing video content for learning and quality learning content.

  • Currently the telephone service using Internet grows and the recent introduction of a smart phone is expected to accelerate the trend. In particular, considering the domestic situation that the wireless broadband (WiBro) system deployed over the nation, the telephone service over WiBro can be a solution toward its fast expansion. Unlike telephone service over a conventional telephone network or mobile network, however, internet telephone cannot guarantee it service quality, which can be severer in a wireless environment such as a WiBro network. Therefore, a more strict and systematic management for controlling the quality of internet telephone service over WiBro in a more efficient way. As the first step to establish the management system, this paper proposes a scheme to manage the quality of internet telephone service over WiBro and introduces a software developed for the purpose. The developed software is installed on a user terminal and facilitates efficient service quality management by measuring the quality of internet telephone service over WiBro in terms of VoIP metric, network metric, and wireless metric.

  • Increased frequency of climate extremes is another face of climate change confronted by humans, resulting in catastrophic losses in agriculture. While climate extremes take place on many scales, impacts are experienced locally and mitigation tools are a function of local conditions. To address this, agrometeorological early warning systems must be place and location based, incorporating the climate, crop and land attributes at the appropriate scale. Existing services often lack site-specific information on adverse weather and countermeasures relevant to farming activities. Warnings on chronic long term effects of adverse weather or combined effects of two or more weather elements are seldom provided, either. This lecture discusses a field-specific early warning system implemented on a catchment scale agrometeorological service, by which volunteer farmers are provided with face-to-face disaster warnings along with relevant countermeasures. The products are based on core techniques such as scaling down of weather information to a field level and the crop specific risk assessment. Likelihood of a disaster is evaluated by the relative position of current risk on the standardized normal distribution from climatological normal year prepared for 840 catchments in South Korea. A validation study has begun with a 4-year plan for implementing an operational service in Seomjin River Basin, which accommodates over 60,000 farms and orchards. Diverse experiences obtained through this study will certainly be useful in planning and developing the nation-wide disaster early warning system for agricultural sector.

  • Korea is concerned with information security industry due to recent leak-out private information of 3 card companies. Executives are aware of damage from breach of security such as personal data spill, is more dangerous than any other financial risks. The information security industry, which was limited in physical security and network security formerly, is evolving into convergence security of public and facility security industry. The field of interest has also been changed into security of smart phone and intelligence image recently, from firewall or Anti-virus. The convergence security is originally about access control of facility, but recently its demand has been increased mostly by public institutions and major companies. The scope of the industry also varies from finance, education, distribution, national defense, medical care to automobile industry. The market of convergence security has been expanded and new various products and services of security of intelligent vehicle, 'U' healthcare, finance, smart grid and key industries are also developed. It is required to create and enhance of new curriculum and cultivate human resources for the development of knowledge information security industry. Raising standard of education and security consciousness of the nation is also necessary to strengthen the global competitiveness.
