Menu is the most common interaction tool to select and execute a specific menu item from multiple menu options. With the very rapid increasing amount of information, various new menu designs have been developed. In this research, the pull-down menu, fisheye menu and grid menu were tested to compare the performance time, error rate, simplicity, usefulness, user friendliness, and overall user preference of each menu type. The grid menu was more efficient in selection speed than the pull-down and fisheye menus when the number of menu-items was 50 and 100. The time needed to choose a menu-item with a grid menu was less affected by the size of menu. The pull-down and the grid menus were considered to be more satisfactory, simple, user friendly, and useful than the fisheye menu. 42.3 percent of subjects indicated that the grid menu was their preferred selection tool among the menus. The grid menu is an efficient and robust alternative menu choice for small and middle size menu list. Further study is required to examine the possibility of grid menu on mobile devices.

Recently, due to technical developments of various storage devices and networks, the amount of data increases rapidly. The large volume of data streams poses unique space and time constraints on the data mining process. The continuous characteristic of streaming data necessitates the use of algorithms that require only one scan over the stream for knowledge discovery. Most of the researches based on the support are concerned with the frequent itemsets, but ignore the infrequent itemsets even if it is crucial. In this paper, we propose an efficient method WSFI-Mine(Weighted Support Frequent Itemsets Mine) to mine all frequent itemsets by one scan from the data stream. This method can discover the closed frequent itemsets using DCT(Data Stream Closed Pattern Tree). We compare the performance of our algorithm with DSM-FI and THUI-Mine, under different minimum supports. As results show that WSFI-Mine not only run significant faster, but also consume less memory.

Recently, many cognitive training programs based on digital contents have been presented, but few digital contents have been produced for children with intellectual disabilities among children with developmental disabilities. Digital contents based training programs are needed to apply remotely untact training programs rather than face-to-face apprenticeship classes for improving the cognition of children with intellectual disabilities. This study was attempted to present the new cognitive training program by analyzing concurrent validity, which was analyzed by the correlation between items by comparing with subtests of K-WISC-IV and items of game based Neuro-World cognitive training program. It was found that there are some validity by analyzing correlation between the subtests of K-WISC-IV and the items of Neuro-World program, which means that it has concurrent validity of some items of Neuro-World program. In terms of reliability, the Cronbach alpha value was 0.794, indicating that game performance of children with intellectual disabilities and the degree of level increase in each game were somewhat reliable. This is considered to be a significant result in future studies for clinical trials of cognitive training tools.

This study presents a method to find the extant central halls with the plan most similar to the remains and to find out and compare the architectural style of extant buildings for the restoration. In the Joseon dynasty, there existed both remains and the extant hall. In particular, the $3{\times}2Kan$ hall is the minimum size that functions as the hall, so the number of comparison articles is small. The subjects are three remains and 29 Extant Halls. The absolute size of the comparison articles are the Area, Ratio of front/side, and the relative sizes are the Ratio of front Eokan/Hyeopkan and Ratio of the front Eokan/the side row. The Daeungjeon remain in Bugjijangsa is similar in absolute size and relative sizes to Oeosa daeungjeon. The Bubdang remain in Seonchalsaji is similar to Sangwonsa daeungjeon in the Area and Ratio of front/side, and similar to Daejeogsa geungnakjeon in the Ratio of front/side and Ratio of front Eokan/Hyeopkan. The Bubdang remain in Seungseonsaji is similar to Seodongsa daeungjeon in the Area, Ratio of front Eokan/Hyeopkan and Ratio of the front Eokan /the side row. Consequently, this method has high value as a way to expand by other comparison articles.

When migrate electronic records, the validation of the required metadata in electronic records and verified with the metadata in the document are also important. This paper presents a method and implements a tool to extract data from files in various formats and use them to validate metadata associated with the files in electronic records. Compared to other metadata extraction tools, especially developed in foreign countries, the standard form of documents used in Korean government is taken into account and metadata is extracted from the content of files. The tool compares the extracted data to encapsulated metadata for validation.

In this paper, we investigate if the new merchant fee system has problems. The fee was fixed by government policies and there were no processes of listening to market participants. Therefore, we suggest improvements as follows. First, large-sized stores take burdens for the rest of stores so credit card companies and the government should try to minimize the increasing rate for large-sized stores. Second, credit card firms need to give VAN companies roles of stabilizing authorizing processes. Third, periodic update requires because of credibility. Fourth, contents of merchant fee should be disclosed to merchants. Fifth, there needs discussions for merchant fees of debit cards.

This article attempts to correct errors in five words related to Shiji (The Grand Scribe's Records) Liezhuan (A Series of Biographies), which are presented in the Great Chinese-Korean Dictionary. The author analyses the problems with meaning interpretations of three words and additional meaning interpretations of two words. The main points of the study are presented in the following. First, in relation to the error correction in meaning interpretation, this study finds out that the explanations of "jiayu," "jiaochi," and "guancai" in the Great Chinese-Korean Dictionary are incorrect. Most of the cases include plausible interpretations of the words that are likely to cause readers to be confused with the meanings. Each of the words should be interpreted as "lend${\rightarrow}$give," "arrangement${\rightarrow}$new decoration, ornamentation, or embellishment after removing old one," and "accept something carefully or accept something after inspection${\rightarrow}$look over carefully or search for something." Second, as for the supplementary correction, this study points out that the explanations of "xiaoshi" and "shennian" are not sufficient. The following meanings for each word should be added, including "display skills" and " be trapped inside one's own mind." Furthermore, when comparing with the different translation versions by scholars at home and abroad, we can come to a following conclusion. The interpretations made by Zheng, Fan-Zhen are the most accurate for the "jiayu" item. With respect to the "jiaochi" item, the interpretations given by Piao, Yi- Feng; Wang, Li-Qi; Yang, Zhong-Xian; and Hao, Zhi-Da are relatively appropriate. The "guancai" item is adequately interpreted by Piao, Yi-Feng and Wang, Li-Qi. In the meaning interpretation of the "xiaoshi," Jin, Yuan- Zhong gave correct explanations. In addition, it is considered that Wang, Zhong provided the most ideal translations for the item "shennian."

The purpose of this study was to compare the asymmetric degree between maxillofacial hard and soft tissues in individuals with facial asymmetry. Computerized tomographies (CT) of 34 adults (17 male, 17 female) who had facial asymmetry were taken. The CT images were transmitted to personal computers and then reconstructed into three-dimensional (3D) images through the use of computer software. In order to evaluate the degree of facial asymmetry, 6 measurements were constructed as the hard tissue measurements while 6 counterpart measurements were taken as the soft tissue measurements. The means and standard deviations were obtained for each measurement using 3D measure, then t-test was used to investigate the differences between each hard tissue measurement and the corresponding soft tissue measurement All measurements used in the present study showed statistically significant differences between the hard and soft tissues. The degree of soft tissue asymmetry was smaller than that of corresponding hard tissue asymmetry in case of chin deviation, frontal ramal inclination difference, and frontal corpus inclination difference. On the other hand, the degree of soft tissue asymmetry was greater than that of underlying hard tissue asymmetry in the measurement of lip canting and lip cheilion height difference The present study suggests that asymmetric differences of hard and soft tissue is observed nu facial asymmetric subjects and thus soft tissue analysis is needed in addition to hard tissue analysis when making an evaluation of facial asymmetry.

This study was designed to determine whether cognitive impairment was evident in patients with SLE. Also, it aimed to examine the association of cognitive impairment with other clinical variables. The subjects consisted of 20 patients with mildly active SLE and 20 healthy controls. Methods : A total of 20 SLE patients and 20 normal controls completed a computerized neuropsychological test battery using Vienna Test System. These included Cognitrone test, Continuous attention test, Corsi block tapping test, Standard progressive matrices. Also, neuro-behavioral cognitive status examination was done. The symptom severity of depression was measured with Beck Depression Inventory, Hamilton Depression Rating Scale, and current medications were documented. Disease activity was rated using the SLE diasease activity index (SLEDAI). Results : SLE patients had poorer performance than normal controls on the tests of Cognitrone, attention, nonverbal IQ and memory, independent of age, education, disease activity, steroid use and depression status. Conclusion : Cognitive dysfunction was not uncommon in ambulatory SLE patients as measured by standardized neuropsychological tests. It seemed to occur independently of various clinical variables. These findings would suggest that cognitive dysfunction in SLE may be explained by reflecting subclinical central nervous system(CNS) involvement, rather than coexisting psychological distress due to chronic illness or side effect of medication.
