The current information system audit merely inspects a web based information system by focusing on checking items that are extracted from structured and information engineering model and object-oriented component model. As a result, the checking item of web contents and design is inadequate. This paper aims to extract audit framework in order to strengthen the audit of web contents and design during the development of the web based information system and to suggest checking items based on audit framework. For this, the web development process and web site evaluation model were studied, compared, and analyzed with the current information system development audit. From a result of the survey, it was found that the adequacy of the suggested audit framework and audit checking items is above the average value. It is believed that the suggested audit framework is helpful for the audit of web based information system.

Information system outsourcing induces firms to concentrate on the core competence and to improve business value by utilizing specialized information systems outsourcing vendors. However, for those strategic effects, the outsourced information systems should guarantee a certain service level. Now companies are considering to adopt SLA(Service Level Agreement) as a method to check the service level of the outsourced information systems in quantitative terms. On the contrary, customer satisfaction survey supports qualitative analysis, and helps companies to understand the qualitative effects on information system more systematically. Recently, the growing use of the internet makes customer satisfaction survey to be carried out on the web. For that reason, lots of researches related to web survey have been performed. But these researches are just focused on finding out only items to be measured and the effect of web survey. In this paper, based on the service quality research model for information system outsourcing, we formalize and propose a web survey process, a system architecture, and a functional structure for information system outsourcing customer satisfaction survey. Additionally, we provide the implementation results for the web survey systems.

With a swift development of information technology, web sites get more important roles as user's living places. This quantitative and qualitative expansion of web sites requires the need for an evaluation framework of web sites from comprehensive perspectives. This study proposes two dimensions for web site categorization and three dimensions for web site evaluation. These dimensions were developed based on the architectural perspectives that have been used to evaluate buildings in the real world for more than a thousand years. First, in order to categorize various web sites, we extracted two dimensions, user's goals and user's behaviors from behavioral architect which approaches user's behaviors in designing buildings. Second, in order to evaluate four web sites groups, we suggested three dimensions, which are firmness, commodity, delight used in evaluating buildings in the real world. Then for each of the four different web sites groups an empirical survey was conducted to verify these three dimensions of architectural metrics. This ends with study implications and limitations.

This study was undertaken to develop web-based nutrition information contents for the older adults. Twenty six domestic web-sites were analyzed and then 12 foreign web-sites and 4 education materials for the elderly of foreign university were benchmarked. Also a lot of literatures on elderly education program were reviewed. A card-sorting task was performed with 8 older adults to ascertain how the target audience organized information about nutrition. The results were as fellows. Among 26 domestic web-sites, 2 sites(7.7%) were only for the elderly. Main topics of information contents for the elderly included 'Importance of Healthy Eating', 'DRI', 'Dietary Guidelines'. Four of twelve foreign web-sites were for the elderly nutrition education. Topics of 'Dietary Guideline', 'Meal Program' were found in 4 sites and 'Importance of Healthy Eating', 'Diet & Disease', 'DRI, 'Food Guide Pyramid', 'Nutrition Fact Labels' were found in 3 sites. Education materials of foreign university dealt with basic information on 'nutrient needs changes related with aging', 'Heart & Bone Healthy Eating Plan', 'Food Guide Pyramid'. Also topics on 'Eating on a budget', 'Eating Out Guideline' were included for practical use for the elderly. Based on card-sorting process, contents framework for web-site was developed and 4 main menus for framework were respectively named as 'Nutrition', 'Meals', 'Foods'. 'Check up Nutritional Health' by panel discussion. Finally we developed nutrition information contents for 4 main menus. We focused on helping older adults recognize the importance of healthy eating and apply the nutrition information to practical use. We expect that the developed framework of contents can be a guideline for indentifying the information needs of older adults in developing effective nutrition intervention program. And we suggest that the survey for target people should be peformed for the web-site to be user-friendly designed and the developed contents be evaluated and revised in the near future.

Topographical features in South Korea is characterized that 70% of territory is composed of the mountains that can experience intense rainfall during storms in the summer and autumn. Efficient planning and management of landscape becomes utmost important since the cutting slopes in the mountain areas have been increased due to the limited construction areas for the roadway and residential development. This paper proposed an efficient way of slope management for the landslide risk by developing Web-GIS landslide risk management system. By deploying the Logistic Regression Analysis, the system could increase the prediction accuracy that the landslide disaster might be occurred. High resolution survey technology using GPS and Total-Station could extract the exact position and visual shape of the slopes that accurately describe the slope information. Through the proposed system, the prediction of damage areas from the landslide could also make it easy to efficiently identify the level of landslide risks via web-based user interface. It is expected that the proposed landslide risk management system can support the decision making framework during the identification, prediction, and management of the landslide risks.

시맨틱 웹(Semantic Web)의 비전에 대한 공표가 이루어진 이래로 이와 관련한 많은 연구가 진행되어 왔다. 그러나 지금까지의 연구가 성공적이었다는 판단을 하기에는 아직 이르다. 본 논문은 시맨틱 관련 연구분야의 두 가지 문제점을 진단한다. 첫째는 '시맨틱 검색'이라는 개념의 합의된 정의가 없다는 것이고, 둘째는 장래의 유관 연구를 바라볼 수 있는 종합적이고 체계적인 시각이 부족하다는 것이다. 이러한 진단 아래, 본 논문은 시맨틱 검색의 개념을 '사용자의 입력에 따라 온톨로지와 같은 시맨틱 기술을 이용하여 원하는 정보를 얻는 행위'로 정의한다. 또한 시맨틱 검색에 대한 이해를 돕기 위해 시맨틱 검색 엔진 분류 프레임워크를 제안하였다. 본 연구에서 제안하는 프레임워크는 (쿼리) 입력문의 처리, 타겟 소스, 검색 방법론, 검색결과의 서열화, 출력 결과물의 데이터 종류, 이렇게 다섯 가지 부분으로 나뉜다. 마지막으로 본 논문은 제시한 프레임워크를 응용하여 기존의 연구결과물을 분석하고 앞으로의 연구 방향을 논하는 것으로 끝을 맺는다.

It takes elementary school teachers long time to search for instructional materials. They have also difficulties with choosing proper contents among much of the overlapping materials. Thus this study set out to investigate the current utilization of web materials by teachers, analyze the materials in the existing homepage, and identify useful materials for teachers. For those purposes, the investigator developed an evaluation framework to analyze science education materials in the existing homepage and analyzed materials using the framework. The materials had developed in the past failed to reflect the demands of teachers, who were the users, actively. Therefore, we took a survey to analyze their demands and reflected the results to establish a set of criteria to analyze materials. After dividing materials according to utilization and format, the external and internal elements of materials were assessed according to the evaluation items. If they systematically select many teaching and learning materials developed for elementary science and make efforts to vitalize their educational usage by sorting out overlapping materials and developing new needed ones, they will be able to save a huge amount of expenses and maximize the efficiency as educational materials.
