This study investigated perceived discomfort and reasons related to use three information technology products (personal computer, mobile phone and digital television remote controller), and extracted the universal design factors. 240 people (30 females and 30 males for four age groups) participated in the one-to-one interview type of questionnaire, and replied to degree of discomfort at level of items and the reasons of discomfort at level of detailed elements for each product. As a result, almost all age groups answered that using input buttons of mobile phone and remote controller and watching display of mobile phone caused discomfort. Binary logistic regression of the detailed elements showed that response rate of discomfort mostly increased with age, except for specific elements such as shape of mouse and remote controller, and location of function button of mobile phone. Some of the detailed elements had high response rate of discomfort from all age groups. The age groups also showed similar tendency for the elements to select one alternative for the reason of discomfort, but not for sound volume and size of mobile phone and button sensitivity of remote controller. Finally, the universal design factors were extracted for each product based on the results, and divided into common factors and factors classified by the age group. Through this study, we identified using practices of various age groups and their demands for the products. It is expected that extracted detailed elements can be considered as important design factors to design the products universally.

This study is an investigation that explication of the reading method of transcription marking, and explains what it means and where to use transcription marking of architectural vocabulary. focusing on timber class vocabulary from on SeoGwolYeongGeonDoGamUiGwe(${\ulcorner}$西闕營建都監儀軌(1831)${\lrcorner}$). This study is reviewed sequentially classifying items according to timber class, stone class, iron class architectural vocabulary. This treatise, named 'Architectural Vocabulary Study (1)', is mainly focused on making out a transcription marking of timber class vocabulary on the documents. But, because of the properties of the UiGwe(儀軌), there are some different expressions used for the same vocabulary. Therefore, the different expressions are referenced according to vocabulary used from the 17th century to the 20c century. This study lists timber class architectural vocabulary of transcription marking on SeoGwolYeongGeonDoGamUiGwe(${\ulcorner}$西闕營建都監儀軌(1831)$\lrcorner$). This study also explicates and explains the meaning of them. In advance, this study compares them with the vocabulary of national language in the middle ages and modern times. If we could explicate the transcription marking of the documents as it is, we can't only recover plenty of vocabulary related with characteristic architecture in the age of later Chosun Dynasty, but also correct wrongly used vocabulary nowadays. With the results, we can standardize and adjust vocabulary use of Korean traditional architecture. In advance, we can correct errors of spelling and mistaken explanation in the Korean Encyclopedia.

Relevance judgment is important in terms of improving the effectiveness of information retrieval systems, and it has been dominant for users to search and use images utilizing internet and digital technologies. However, in the field of image retrieval, there have been only a few studies in terms of identifying relevance criteria. The purpose of this study aims to identify and characterize the non-relevance criteria from the failed image searches. In order to achieve the purpose of this study, a total of 135 participants were recruited and a total of 1,452 criteria items were collected for this study. Analyses and identification on the data set found thirteen criteria such as 'topicality', 'visual content', 'accuracy', 'visual feature', 'completeness', 'appeal to user', 'focal point', 'bibliographic information', 'impression', 'posture', 'face feature', 'novelty', and 'time frame'. Among these criteria, 'visual content' and 'focal point' were introduced in this current study, while 'action' criterion identified in previous studies was not shown in this current study. When image needs and image uses are analyzed with these criteria, there are distinctive differences depending on different image needs and uses.

The recent international comparative studies such as PISA(Program for International Student Assessment) and TIMSS-R(Third International Mathematics and Science Study-Repeat) provide results of relative mathematics achievement of participating countries. The purpose of this paper is to compare the mathematics results of PISA and TIMSS-R. To make PISA and TIMSS-R results comparable, they were standardized. The close investigation of these standardized results reveals that the two Asian countries(Korea and Japan) and several English speaking countries have the commonality in mathematics achievement. Thus this study looks for patterns and similarities within a group of Asian countries(Korea and Japan) and Western countries(the U.S and Australia) by in-depth analysis of PISA mathematics achievement based on item response theory. As a result, it was noted that Western countries tend to perform well on open constructed items and are likely to perform better when an item involves less formal mathematics. On the other hand, Asian countries perform well when an item involves numeric or algebraic computation related to curriculum-based content, but they are relative poor at an item calls for verbal explanations or interpretations of graphs.
