As the economical and cultural levels become higher, the public have more various and new cultural desires, leading to an increase in the number and kinds of cultural facilities. Out of all the cultural facilities built in such a trend, art museums are the yardstick for a certain nation's cultural level, and the number of art museums is gradually increasing every year in Korea, as a cultural space where the public can make cultural exchanges with artists. On the contrary to the increasing number of art museums, however, the number of art museum visitors is decreasing every year, so various attempts are made to activate art museums in Korea. Thus, this study aims to seek a plan to activate the space of an art museum by improving the physical movement of art museum visitors, especially targeting small-sized ones out of all the art museums in Korea. For accurate analyses and verifications, this study used the visibility-ERAM program. As a result of analyses, this study found out and reconsidered several problems related to the space of art museums, and based on the results, the researcher could verify the related hypotheses, further comprehending possible errors of the proposed solution to those problems and supplement in a short period of time. Since such an analysis method and process has objective accuracy, it is expected that the results of this study will be used as basic data for future plans to activate the space of art museums.

The purpose of this study is twofold: it suggests appropriate sizes in menswear slim-fit jackets according to brand zones and number of buttons, as well as jacket patternmaking methods according to jacket styles by surveying and comparing the overall present status of patternmaking and production for both men's slim-fit and classic-fit jackets. The researcher conducted interviews with patternmakers of sixteen brands with prepared questionnaires. Data were analyzed by descriptive statistics using SPSS 12.0. The results of this study are as follows: first, for the production ratios of jacket style, the jacket styles' respective proportions differ distinctly according to brand zone. Second, for a jacket with the same number of buttons according to brand zone, the size in character-casual brand zone (character casual can be defined as high quality brands producing designer style clothes) is slightly bigger than the men's formal suit. As the number of buttons increases, there are increases in the chest, waist and hip circumference; on the other hand, the front neck width and the distance from the shoulder neck point to the bottom of the lapel both decrease. Furthermore, the amount of wearing ease in the chest, waist, upper arm circumference, and sleeve curve is less in slim-fit jacket styles than in classic-fit jacket styles. Fusible interfacing alone is used in slim-fit jackets, while sew-in interfacing is used in combination with fusible interfacing in classic-fit jackets. This research concludes that when slim-fit men's jackets are manufactured, appropriate patternmaking and manufacturing methods should be considered.

Objectives : Trend of R&D of herbal medicine for dementia treatment was examined based on the quantitative information analysis for establishing the national strategy of research on dementia treatment with oriental medicine. Methods : Definition was made to clarify the technology for development of herbal medicine for dementia treatment. Based on the initial keyword provided by experts in the field, queries were compounded to conduct search in the search engines of WoS and DWPI. The raw data (papers or patents) extracted from the initial search were examined by expert-review before objects of analysis were determined. Then, the accumulated data was analyzed in terms of year, country and organization, which led to examination of the trend of R&D. And the research performance evaluation for dementia treatment technologies was also made in terms of country, organization and researcher based on the forward citation analysis. The international cooperation intensity was examined on the basis of analysis of network by researcher before analysis results were put together to select lead researchers. Results : According to the quantitative information analysis of 1,330 articles that were selected as analysis objects, the number of papers on natural products research for dementia treatment has increased by around 4.6 times in recent five years. This indicates that the intensive studies have been underway recently. It was found to be the US that had the highest level in research filed of herbal medicine for dementia treatment and the highest capacity of international cooperation for that purpose. On the contrary, Korea had the share of papers at 5.1%, the number of countries in cooperation research at 8, and the article quality index at 0.40, showing that the qualitative level was insufficient, compared to the quantitative outcome. In particular, Korea was found to have no intensity of international cooperation among researchers. In case of patent, the results of information analysis of 305 patents selected as analysis objects demonstrated that China had the highest share while Korea had the very low frequency of patent application quantitatively. Conclusions : In this study, the research to develop herbal medicine for dementia treatment has recently drawn much attention that has spread around the globe. Therefore, these results suggest establishing the strategy to develop technology for dementia treatment with oriental medicine in the future based on quantitative information analysis.

Purpose: This study aimed to assess the computer monitors used for analysis and interpretation of digital radiographs within the clinics of the Oral Health Centre of Western Australia. Materials and Methods: In total, 135 computer monitors(3 brands, 6 models) were assessed by analysing the same radiographic image of a combined 13-step aluminium step wedge and the Artinis CDDent 1.0^® (Artinis Medical Systems B.V.^®, Elst, the Netherlands) test object. The number of steps and cylindrical objects observed on each monitor was recorded along with the monitor's make, model, position relative to the researcher's eye level, and proximity to the nearest window. The number of window panels blocked by blinds, the outside weather conditions, and the number of ceiling lights over the surgical suite/cubicle were also recorded. MedCalc^® version 19.2.1 (MedCalc Software Ltd^®, Ostend, Belgium, https://www.medcalc.org; 2020) was used for statistical analyses(Kruskal-Wallis test and stepwise regression analysis). The level of significance was set at P<0.05. Results: Stepwise regression analysis showed that only the monitor brand and proximity of the monitor to a window had a significant impact on the monitor's performance (P<0.05). The Kruskal-Wallis test showed significant differences (P<0.05) in monitor performance for all variables investigated, except for the weather and the clinic in which the monitors were placed. Conclusion: The vast performance variation present between computer monitors implies the need for a review of monitor selection, calibration, and viewing conditions.
