This study aims at designing and calculating of the information index for efficient implementation of the regional information policy. The content and scope of this study are designing the struture of information index, measuring the informatization level in major cities of Korea and inducing rough idea for better performing of Korea information policy. Thereby we calculated tables ofinformation indexon seventy-eight cities in Korea from 1985 to 1994 and also basic strategy for better policy implementation. And we found that every citities share the benefit almost equal in the use of old media but not in that of new media. It can be expected that the bovernment will make a good use to get procedural validity in the course of designing some information policy based upon quantitative data.

초고속 정보통신망의 발전과 더불어 컴퓨터의 급속한 보급 및 웹 기술의 발전으로 교육 분야에서도 큰 변화가 일어나고 있다. 인터넷의 대중화로 정보화 마인드가 확산됨에 따라 다양한 학습이 이루어졌고, 이에 따라 자격증 역시 정보화 지수로 중요한 위치를 차지하고 있다. 7차 교육과정에서는 저학년에도 컴퓨터 교육이 이루어지고 정보소양인증제도가 실시됨에 따라 자격증 취득에 대한 요구가 높아지고 있다. 본 논문에서는 많은 컴퓨터 관련 자격증 중에서 정보처리 기능사 필기시험을 가상공간인 웹 상에서 설계 및 구현해 봄으로써 실업계 고등학교 학생들이 보다 손쉽게 자격증을 취득하는데 도움을 주도록 하는데 있다. 이러한 웹에 기반한 교육적 활용의 한 모델로서 자기 주도적 학습이론과 수준별 학습이론을 정보처리 기능사 필기시험에 적용하였다. '자격증 시험을 위한 웹 기반 문제은행 시스템'은 정보처리 기능사 필기시험뿐만 아니라, 문제은행 방식의 많은 컴퓨터 관련 자격증 필기시험에도 적용 및 응용이 가능하다.

In 2015, drought was at the worst stage of devastation in Soyanggang Dam watershed. The purpose of this study is to trace the drought area around Soyanggang dam watershed by using Terra MODIS image because it has the ability of spatio-temporal dynamics. The MODIS indices, which included the enhanced vegetation index (NDVI), were extracted from MODIS product MOD13 16-day composite datasets with a spatial resolution of 250m from 2010.01.01 to 2015.06.30. We found that application of Vegetation Condition Index (VCI) and Standardized Vegetation Index (SVI) was suitable for monitoring the drought area. The result can be used to acquire the drought data scattered and demonstrate the potential for the use of MODIS data for temporal and spatial detection of drought effects.

In the present knowledge and information society, every citizen can enjoy benefits of various advanced technologies such as information and communication technology(ICT) and smart technology. Nowadays everybody has to have some level of information literacy and application ability in order to enjoy benefits from various advanced technologies. In additions, knowledge and practice will about information and communication ethics are also required for all. Currently we need some kind of standards to evaluate and model everybody's information literacy and application capability. In this sense, information culture index has been developed to check information literacy and application capability of every citizen for various aspects of daily life. Information culture index consists of three standards, that is, application, awareness, and norm, respectively. Application standard indicates how information contents and skills are generalized for all. In other words, it is concerned with how every citizen can understand information literacy and use information skills in his or her daily life. Awareness standard is concerned with how well everyone can respect and trust others in the current information culture community. Norm standard is concerned with how everyone can use information communication services according to his or her desirable sense of information and communication ethics. The purpose of this paper is to analyze correlation between academic background and three standards of information culture index, that is, application, awareness, and norm. For this purpose, we use 2-year national survey works for information culture. After thorough statistical analysis, we can conclude that, awareness and norm standards do not show a meaningful correlation with academic background while application standard shows a meaningful correlation with academic background, It means that, the higher academic background one has, the higher application standard one can achieve. We expect that our correlation analysis results can be helpful to spread of information education and information culture in the future.

This study ultimately aims to suggest directions for development of U-City Competitiveness Index through thorough analyses of U-City competitiveness concepts and previous research in U-City-related index. In an attempt to reach the aforementioned goals, the concept of U-City competitiveness is presented based on existing publications on informatization age, future city, and U-City. Next, insights on the development of U-City Competitiveness Index are provided via analysis of research on indices regarding U-City and future city. Finally, the process of developing UCity Competitiveness Index and cautionary comments for each developmental step has been provided. Based on the research results, U-City competitiveness refers to the ability to respond to demands of residents in a timely manner as well as to manage U-City, ICT, U-City infrastructure, and U-City services that maximizes the efficiency of urban space management. In order for proper assessment of these criteria, development of assessment tools, selection of indices, standardization, allocation of weight per index, and construction of assessment framework are required.

Because of the development of digital technologies and information-oriented products, the importance of user interface design and usability are increasing in recent year. So we need a systematic and rational way to measure and manage how effective the improvement of user interface is. The purpose of this study is to develop measurable ‘Usability Improvement Index' which signify how much usability has improved in user interface design. First, I made the framework of measuring and evaluating usability through analysis of existing usability metrics and previous studies. Then, I suggested the process of calculating 'Usability Improvement Index' based on categorizing characteristics of measurable usability and definition of usability metrics. The process is as in the following : measuring the present level of usability, analysis of problems, making alternative user interface design, measuring the improved level of usability, calculating Usability Improvement Index. For verification, the case study on application of Usability Improvement Index to usability improvement of application software of digital camcorder presented. This study is expected to assist 'goal oriented user interface design' and to manage usability systematically.

The regional differences between urban and rural areas make many diverse differences. There are various differences between urban and rural areas such as economic gap and cultural gap. There is also a difference between urban and rural areas in accessing and utilizing information. The purpose of this study is to clarify the relationship between the information gap and the income gap among farmers and fishermen groups, where information gap is considered to be more serious than other groups. In other words, we tried to examine whether the information gap between farmers and peasants affects the income gap. The purpose of this study is to analyze the relationship between informatization level and income of farmers based on the information gap index and survey results conducted every year by the government. The results show that there is a statistically significant positive relationship between the informatization level of farmers and household income. In addition, the trend of the regression coefficient is positive, suggesting that the government needs various informatization policies to increase the informatization level of farmers.
