  • Recently, there are great variations on concepts and rolls of information system as the radical growth in information technology. A systematic MIS evaluation is requested for effective management and operation of information system. Although many researches on MIS evaluation have been progressed, the evaluation of the user satisfaction is limited by evaluating from the each system's result because of the diversity of view points and inclusion of MIS introduction. Therefore, in this paper, a conceptual framework is suggested to evaluate MIS synthetically that is changed by the result of existing MIS evaluation. So to speak, a new evaluation framework is suggested by synthesizing various view points and evaluation method that suggested from the existing MIS evaluation such as user satisfaction of results as the introduction of MIS and the satisfaction of variation of entire organization.

  • The rapid progress of the intermodal freight transportation in recent years has induced fierce competition among the adjacent hub ports for container transport. This brings increased attention to the evaluation of the port competitive ability. But it is not easy to evaluate the port competitive ability because this belongs to ill-defined system which is composed of ambiguous interacting attributes. Paying attention to this point, this paper deals the competitive ability of container port in Far-East Asia by fuzzy integral evaluation which is adequate to interacting ambiguous attribute problem. For this, the proposed fuzzy evaluation algorithm is applied to the real problem, based on the factors such as cargo volumes, costs, services, infrastructure and geographical sites These are extracted from the precedent study of port competitive ability, etc. The results show that the port evaluation factors come in following order ; services, costs, infrastructure, geographical sites and cargo volumes. There are some interactions(interaction coefficient, ${\lambda}=-0.664$ between evaluation attributes. The port competitive ability comes in following order : Singapore, Hongkong, Kobe, Kaoshiung and Busan. According to the sensitivity analysis, the rank between Busan and Kaoshiung changes when ${\lambda}=0.7$. From the analysis of the results, we confirmed that the proposed fuzzy evaluation algorithm is very effective in the complex-fuzzy problem which is composed of hierarchical structure with interacting attributes.

  • Purpose: The purpose of this study is to identify key performance evaluation items and factors that are effective and practical for project management of defense standard standard improvement projects, and to develop a quantitative performance evaluation model. Methods: For the development of a performance evaluation model for defense standard improvement projects, we analyzed past major project performance and derived evaluation items and factors. To increase the objectivity and efficiency of project evaluation, we developed an evaluation index that enables relative evaluation of evaluation targets, and calculated the main importance of evaluation items using the Analytic Hierarchy Process (AHP) method based on the main opinions of expert groups. Results: The study resulted in the identification of main performance items for defense standard improvement projects, which were classified into defense standard conformity review performance and defense standard improvement performance items. We also simplified the evaluation model by integrating various evaluation items into similar evaluation factors. Additionally, we developed a quantitative evaluation index that enables relative evaluation of the targets and verified the objectivity and validity of the suggested performance evaluation model by reevaluating it using performance data from past commissioned professional institutions Conclusion: Developing a quantitative evaluation model for defense standard improvement projects is expected to provide a means of measuring the effectiveness of the project, and to be used as a tool to determine the appropriateness and effectiveness of medium and long-term project plans.

  • This study analyzed the trends of patents for unmanned technology used in agriculture. The target countries for this survey of patent data were Korea, the USA and Japan as well as the countries in Europe. The indices used in this study to analyze the patents were the CPP (Cites Per Patent), PII (Patent Impact Index), and PFS (Patent Family Size). The total effective patents for unmanned technology used in agriculture were 1,080 cases. The number of patents in the USA, Japan, Europe, and Korea were 541, 326, 128 and 85 cases, respectively. Among the total effective patents, the evaluation scores for selected important patents were calculated by applying commonly used weights to each index, and the top 10 patents were selected as important patents. The results showed that all the top ten patents are owned by the United States and that the United States is an advanced country in the field of unmanned technology used in agriculture. The evaluation score of the important patents using the existing method was biased toward the PII index among the three patent evaluation standards, and the effects of the number of claims and the PFS were relatively small. Therefore, a reliable patent analysis in the field of unmanned technology used in agriculture needs to reflect the overall evaluation factors taking into consideration the scope of the evaluation factors.

  • In the current Internet environment where there is high space complexity of information, search engines aim to provide accurate information that users want. But content-based method adopted by most of search engines cannot be used as an effective tool in the current Internet environment. As content-based method gives different weights to each web page using morphological characteristics of vocabulary, the method has its drawbacks of not being effective in distinguishing each web page. To resolve this problem and provide useful information to the users, this paper proposes an evaluation method based on categories. Category-based evaluation method is to extend query to semantic relations and measure the similarity to web pages. In applying weighting to web pages, category-based evaluation method utilizes user response to web page retrieval and categories of query and thus better distinguish web pages. The method proposed in this paper has the advantage of being able to effectively provide the information users want through search engines and the utility of category-based evaluation technique has been confirmed through various experiments.

  • The social welfare facilities are trusted by the government for the development of appropriate welfare services and their delivery systems. They aim to provide people with professional social welfare services and, for this purpose, they develop ways to effectively operate facilities and to deliver the services efficiently. So far, the five consecutive evaluations based on the Social Services Act have suggested the effective and systematic ways of operating social welfare facilities. Through these efforts, they established an important basis for the balanced development and further advancement of social welfare facilities. Nevertheless, people have continually pointed out problems concerning the evaluation system of social welfare facilities. Accordingly, these problems have the necessity of investigation for reformed directions by means of effective control and evaluation system for the operation of social welfare facilities. Therefore, this study aims to suggest convergence models for improving the social welfare facilities evaluation system.

  • Web-based information resources should be managed and used methodically in the same manner as the paper-based resources are managed and used. It is necessitated by the prevalence of web-based delivery of a variety of information. To develop a web-based digital collection, it is critical to establish a set of standardized evaluation criteria for web-resources. The evaluation criteria needs to include authority, trustworthy, reliability, functionality, relatedness, accessibility, structure, design, user support, and security related matters. However, it is also necessary to have certain flexibility to either emphasize or include particular evaluation criteria to reflect varying characteristics of the web resources especially for the purpose of developing an effective digital collection. In addition, it is essential to review the evaluation criteria with respect to value, demand, duplication prevention, and intellectual property, which are relevant to the web-based digital collection development. Finally, various strategies were suggested as means to develop more effective web-based digital resource collection. These strategies include organizing a selection committee to ensure the objectivity and consistency in web-resource evaluation; developing a model for web-based digital resource collection; sharing new standards, protocols, markups, and metadata with other digital libraries; and developing user-centered digital resource collection.

  • Cognitive model, that is cognitive architecture, is the model expressed with computer program to show the process how human solve a certain problem and it is continuously under investigation through various fields of study such as cognitive engineering, computer engineering, and cognitive psychology. In addition, the much extensive applicability of cognitive model usually helps it to be used for quantitative prediction of human Behavior or Natural programming of human performance in many HCI areas including User Interface Usability, artificial intelligence, natural programming language and also Robot engineering. Meanwhile, when a system designed, an usability test about conceptual design of interface is needed and in this case, analysis evaluation using cognitive model like GOMS or ACT-R is much more effective than empirical evaluation which naturally needs products and subjects. In particular, if we consider the recent trend of very short-end term between a previous technology development and the next new one, it would take time and much efforts to choose subjects and train them in order to conduct usability test which is repeatedly followed in the process of a system development and this finally would bring delays of development of a new system. In this study, we predicted quantitatively the human behavior processes which contains cognitive processes for menu selection in touch screen interface through ACT-R, one of the common method of usability test. Throughout the study, it was shown that the result using cognitive model was equal with the result using existing empirical evaluation. And it is expected that cognitive model has a possibility not only to be used as an effective methodology for evaluation of HCI products or system but also to contribute the activation of HCI cognitive modeling in Korea.

  • The purposes of the study were to identify knowledge and skill levels required for effective nutrition teachers and to compare perceived need and dietitians' self-evaluation of the knowledge and skills. A total of 60 knowledge statements and 70 skill statements associated with 11 job functional areas were specified through a literature review and expert panel reviews. A total of 457 dietitians working at school foodservices in Seoul and Gyeonggi province were surveyed using a self-administrated questionnaire and 148 responses were returned. Excluding responses with significant missing data, 142 responses were used for data analysis. In terms of knowledge, 'sanitation, food safety and employee safety(4.60)' category received the highest perceived need score, followed by 'nutrition education(4.56)' and 'nutrition counseling(4.45).' The knowledge category that received the highest self-evaluation was 'nutrition and menu management(3.66)' while the category that received the lowest self-evaluation was 'teaching practices(2.83).' In terms of skills, the highest perceived need was associated with 'nutrition education(4.49)', followed by 'sanitation, food safety and employee safety(4.46)' and 'nutrition counseling(4.39).' The dietitians rated their skills related to 'sanitation, food safety and employee safety(3.67)' the highest but their skills related to 'teaching practices(2.84)' the lowest. The dietitians' self-evaluated knowledge and skill scores were significantly lower than their perceived need of the knowledge and skills in all job functional areas(p<0.001). A quadratic analysis based on the requirement and self-evaluation of the knowledge and skills revealed that priorities of the education programs targeting school nutrition teachers or students preparing to be a nutrition teacher should be placed on improving knowledge and skills related to nutrition education, nutrition counseling, teaching practices, sanitation and employee safety, and nutrition and menu management. Educational programs for nutrition teachers should be designed to decrease the gaps between the need and self-evaluation of the knowledge and skills for effective nutrition teachers. The findings of the study can be used to develop education materials for nutrition teachers. The knowledge and skills identified in the study should be updated and revised regularly to reflect changes in regulations and current practices in school foodservice programs.
