  • Machine translation (MT) quality assessment is an outstanding problem. In the present situation in which the quality of machine-translated products are far from the user\\`s satisfaction objective evaluation of MT system is a prerequisite to building mutual trust between the users and the vendors stimulating constructive competition among the developers and finally leading to improve the quality of MT systems. Especially there emerges a need for an intensive study on how to evaluate the quality of MT systems from both linguistic and data processing aspects and to secure a steady improvement of the translation quality. With due regard to such points we in this paper present a linguistic evaluation of English-to-Korean machine translation based on a test suite composed of 3.373 sentences that were classified into their linguistic phenomena and complexity levels and report the experimental results made from several commercial MT systems.

  • The aim of this study was to discover the correlation between users cognitive style and their attitude towards evaluating the system. Postgraduate students cognitive styles were defined as Verbaliser/Imager and Wholist/Analytic, and the functionality and ease of learning features of a Web-based OPAC(Online Public Access Catalogue) system were evaluated using a combined evaluation methods: interviews for the preliminary survey, a questionnaire far the central data collection, and a psychometric approach for the judgement of students cognitive style using Ridings CSA(Cognitive Style Assessment) tool. Forty-four postgraduate student volunteers responded and data was analysed using SPSS(Statistical Package for Social Science) for Windows. The statistical analysis of each feature of the evaluation, the correlation between the variables, and the features were explored using Pearsons correlation coefficients(r). In exploring the effects of the cognitive styles of individuals, this study has failed to reveal a significant (P < 0.05) correlations in the interactive Web-based OPACs evaluation. It could be said that the contribution of cognitive styles to evaluating Web-based OPACs is likely to be weaker than that of non-cognitive (or demographic) variables.

  • Since the introduction and operation of BF certification, a total of 6,432 certificates has been issued until February 2020, of which educational research facilities make 1,091 cases (754 preliminary certification, 337 main certification) out of 6,237 buildings, acquiring BF certification of about 20%. Qualitative evaluation is conducted with focus on the three items of BF-certified building evaluation index, which are medium facilities, internal facilities, and sanitary facilities, and major keywords are the deducted through the Text Mining analysis of the derived results. As a result, problems with access paths occurred in the case of the facilities, and assessment indicators for users were found to be necessary among the assessment of the steps of the internal facilities. Finally, we could see that sanitation facilities needed to improve toilets installed in residential development facilities. Based on the results obtained, the study seeks to suggest directions for improving the evaluation index required for BF-certified school facilities.

  • The Soil and Water Assessment Tool (SWAT) model users tend to use the readily available input dataset, such as the Ministry of Environment (MOE) land cover data ignoring temporal and spatial changes in land cover. The SWAT model was calibrated and validated with this land cover data. The EI values were 0.79 and 0.85 for streamflow calibration and validation, respectively. The EI were 0.79 and 0.86 for sediment calibration and validation, respectively. With newly prepared landcover dataset for the Doam-dam watershed, the SWAT model better predicts hydrologic and sediment behaviors. The number of HRUs with new land cover data increased by 70.2% compared with that with the MOE land cover, indicating better representation of small-sized agricultural field boundaries. The SWAT estimated annual average sediment yield with the MOE land cover data was 61.8 ton/ha/year for the Doam-dam watershed, while 36.2 ton/ha/year (70.7% difference) of annual sediment yield with new land cover data. Especially the most significant difference in estimated sediment yield was 548.0% for the subwatershed #2. Therefore it is recommended that one needs to carefully validate land cover for the study watershed for accurate hydrologic and sediment simulation with the SWAT model.

  • This study was designed to develop a website for providing nutrition information and education for college women and young women. The website focuses on two topics ; general nutrition and desirable weight control. This program is located at http : // www.ezydiet.co.kr. This program is composed of 5 major sections. The first two sections were designed to provide information ; one for general nutrition, and the other for providing information regarding weight control. The first section includes information regarding young adult women's diet, nutrition standards, such as the RDA or Korean Food Pyramid, drinking and smoking. The second section coveres information regarding desirable control, foods with high or low calories, eating disorders and popularly used dieting methods. The third section is for simple nutrition assessment, consisting of assessment of ideal body weight and obesity, energy requirements, and eating habits. The fourth section was designed to introduce and help users to apply behavioral modification techniques, such as monitoring, goal setting, stimulus control and reinforcement. The final section was designed for meal planning, by introducing a food exchange list and menu examples for one week. The characteristics of this web-based program are as follows ; 1) provide nutrition information systematically, 2) involve sections for the participation of the user, 3) include food pictures to help understanding of nutrition information, 4) include management modules for some sections to revise or update the information. One-hundred and ten female university students participated in the evaluation of this website. The evaluation results were favorable. About 90% of subjects rated that this program covers major topics 'well ' or 'very well', and that it was 'easy'to 'very easy'to understand the contents on website. Two-thirds of subjects rated quite positively on questions regarding attractiveness, overall quality and technical quality of website. In addition, about three-fourths of subjects answered that this website was helpful in increasing nutrition knowledge and in applying nutrition information into daily life. These results suggested the possibility of using a website as a means of providing nutrition information and education for young adult women.

  • As time gees by, the function and role of website become more important. Therefore, it is very critical to evaluate and improve continuously the website to the purpose. Many previous studies show that some website evaluation factors will influence the user satisfaction and revisit to the website. The website evaluation criteria from the previous studies related to the university library website evaluation were classified into five assessment criteria which are design, contents, user interface, reliability, and site management. In the results, some significant suggestions were found out. User satisfaction is seriously affected by user interface, and user's intention to revisit is influenced by contents and reliability, but there may not be a close connection between them. Besides, the evaluation method in this study may be applicable to the new website-improving approach of website administrators and researchers.

  • The research reports the results from an investigation of various measurement elements and techniques appropriate for the economic assessment of academic libraries, with a view to apply them in future evaluation of academic libraries in Korea. Two libraries participated in the pilot study. In one library, CVM (contingency valuation method) was applied to services ranging from circulation, electronic collection, reference, user education and facility. In the second library, three different methodologies--time value, alternative service value and CVM--were all applied to measure the value of electronic collection. The research provides analyses of measurement elements used, study procedures and measurement results. Based on these analyses, the study also makes suggestions in the areas of measurement goals, service, users and the calculation of B/C ratios that need to be taken into consideration in order to execute reliable and valid assessment of academic library's value.

  • Since the middle of 1990s, in Korea a few researches on the optimal management technologies combining numerical model and GIS for the management of water environment in drinking watershed area and reservoir such as Paldang Lake have been carried out. In this study, the integrated water environment management system was been suggested to efficiently reflect the public awareness of the environment by integrating the web based distributed data collection system, GIS, public hearing system and water quality model. As all the components of the system have been developed using the World Wide Web and all data have been collected from the relevant agencies through the Internet, the water quality model could be implemented on the web directly. In consequence, the environmental geographic information in Paldang Lake could be acquired and analyzed through the Internet. The system can rapidly respond to the public right to know on environment, so the public will willingly participate in the governmental projects on environment. To verify the usability of the developed system, it has been applied to Paldang Lake. Especially when the web based model has been used, users can easily and confidentially get the prediction results by applying the minimum number of parameters for the water quality model. This model will provide clearness and scientific bases in the process of water quality prediction for the sensitive sites where there are critical conflicts between the residents and the developers. In this study, rapid water environment management technique without spatial and time limit has been suggested, which can contribute to the efforts on the government and the public participation.

  • As the number of web users is increasing, the leakage of personal information is increasing. If some personal information is leaked, the victim can suffer from material damage or mental damage at the same time. Most of the leakages are result from the people who works for the personal information by accident or design. Hence, the Ministry of Public Administration and Security proposeed the measuring index and enumerates the details. The index is used in a system to check protection of a personal information. However, because this system is used to evaluate after the leakage, it cannot be used to construct some security system or programming a security system. To solve this problem, it needs to express the diversity of items and be able to count what assessors want to count. Thus, a summary sheet which displays the result of the tool will be presented in a radial form graph. Details will be presented as a bar graph. Therefore, it will be proposed that the tool can grasp the weak point and propose the direction of security.

  • Lately the increase of unemployment and freeters, the use of mobile applications for part-time jobs has been increasing. This study identifies the problems of mobile job applications and focuses on domestic applications: 'Albamon' and 'Albachunkuk'. By conducting surveys and in-depth interviews based on Peter Morville's Honeycomb model. The usability assessment, the proposed improvement results are as follows: First, unhealthy establishments and overlapping job blocking filters should be further strengthened. Second, a design to tailor to the 20s age group, who are the main user of the application, is needed. Third, a fully customized part-time job listing is needed for users on the application landing page. Fourth, the application requires verification procedures for the document preparation regarding work contracts and reporting of employers. This study hopes to add to the improvement of job-seeking application services in Korea.
