For plastics samples, a method using combustion ion chromatography was selected as a method for rapid low-cost analysis to test whether hazardous substances are contained or not. Using combustion ion chromatography, a verification test for F, Cl and Br compounds generated a linear calibration curve with a correlation coefficient of $r^2$ = 0.999~1.000 in the calibration range from 0.5 to 4.0 mg/kg. The detection limits were found to be 0.005~0.024 mg/kg and quantitative limits were found to be 0.014~0.073 mg/kg. The recoveries of combustion ion chromatography using certified reference material (CRM) were found to be 95.5~104.9%. Based on these results, a proficiency test was conducted together with several laboratories in and out of the country, to make comparative analysis of the results from each laboratory. As a result, the data supported the use of combustion ion chromatography as an effective analysis method to deal with regulations for halogen-free electronic products and for other hazardous substances in the electronic products.

Recently, the researches based on vision about user attention and action awareness are being pushed actively for human computer interaction. Among them, various applications of tabletop display system are developed more in accordance with touch sensing technique, co-located and collaborative work. Formerly, although supported only one user, support multi-user at present. Therefore, collaborative work and interaction of four elements (human, computer, displayed objects, physical objects) that is ultimate goal of tabletop display are realizable. Generally, tabletop display system designs according to four key aspects. 1)multi-touch interaction using bare hands. 2)implementation of collaborative work, simultaneous user interaction. 3)direct touch interaction. 4)use of physical objects as an interaction tool.

Purpose - The objective of the paper is to examine display techniques and tools at traditional clothing stores to improve the traditional market. Since most research has been done theoretical and model based approaches, changing business environments requires more holistic and detailed facts to apply or develop a retail business strategy. Research design / data / methodology - The study employs qualitative research such as direct observation as well as direct interview and telephone interview from May 7 to Jun 2, 2012. The paper examines lighting, various display techniques and tools. The analysis of 80 store pictures for them had been done three examiners with agreement. Results - Sample garments are displayed on the walls; the racks of hangers are attached on the upper part of the walls; there is indirect lighting only. Furthermore, the merchandises are displayed, without any consistency, on various sizes and shapes of hangers, only on the owners' arbitrariness. When considering that the Korean traditional fabrics (Juddan) have a little pattern and colors as their important elements for displaying. Conclusions - The findings of this study show that the retailers in the traditional market need to have lessons on colors and to learn how to use the specific lighting and to display merchandise.

The registered-properties guideline was adopted to preserve the facade of existing cultural assets with effect and alter the interior space freely. But many problems have been occurred over all the converted buildings with the passing of the years as a result of unfeasible design guidelines. Accordingly, the thesis is to propose the problem and assignment in a setting for a display through the conversion for exhibition of Korean traditional houses designated as modern cultural heritage focused on Riwhachang Choi Sunu House. The results are as follows; The exhibition circulation is continuously connected with each room, considering the previous life-style. The interior design elements are preserved according to the stand-up and sitting style. It is possible to put on one sided wall display in stand up style(Rhiwhachang), and island showcase display in sitting style(Choi Sunu House). And also these apparatus is suitable for the existing window pattern and frame. Therefore, this study is to suggest an assignment of design guideline for exhibition reuse in Korean Traditional Houses as well as the sustainable preservation of cultural assets as modern house.

There are various methods in the flat panel display manufacture. The cost reduction effect is very big in case of using the screen printing method. The screen printing method is much used in the process of forming PDP barrier and can apply to the process of arranging the pillars for maintaining the vacuum gap of the vacuum glazing panel. The pillar which is one of the core elements for comprising vacuum glazing maintains the vacuum gap overcoming the vacuum pressure difference with the atmospheric pressure generated in vacuum glazing. At the same time, the deformation phenomenon by vacuum pressure is relived. In this paper, by using FEM about three considered in the pillar design and arrangement kinds of limiting factors, the simulation was performed. The pillar optimum arrangement method at within the maximum allowable tensile stress and heat transfer coefficients according to the arrangement try to be presented based upon the analyzed result data review and this validity tries to be verified by FEM.

Installation art(I.A.), which has appeared since 1940s against the loss of human nature and hackneyed art caused by materialism, is in pursuit of contact with audience and various artistic experiments. Many features of I.A. - to try contact with audience, to do experiments connecting different genres of art, to regard time and nature as elements of art and to use high technology - could give good ideas for contemporary display(S.W.D.) design. This study is a basic work to suggest new S.W.D. design through artistic principles of I.A.. First, I.A. and S.W.D. design were studied theoretically. Next, spatial expressions were extracted from I.A. and the case study was proceeded to seek the co-relationship of spatial expressions and display design. For a case of Shiseido, it could be evaluated very high because it adapted spatial expressions of I.A. successively. The S.W.D design could be more effective presentation when it has close contact with audience and various experimetal and artistic ways of Installation art.

Wearable devices, attached to the human body, track and enhance users' activities, health, and communication. Therefore, considering ergonomic factors in product design is crucial. However, previous research has somewhat overlooked the importance of integrating ergonomic design elements into a broad spectrum of design factors. This study aims to examine the impact of physical attributes inherent in smart wristbands and smartwatches on the perceived functional value, specifically, perceived usefulness, ease of use, and fit. A survey was conducted among 289 US adults who had experience using smart wristbands or smartwatches. The collected data were analyzed using descriptive statistics, factor analysis, Cronbach's alpha, t-test, MANOVA, and regression analysis in SPSS version 29. The results showed that the shape of the front display significantly influenced perceived ease of use, and the product's weight had a substantial impact on both perceived ease of use and fit. Furthermore, distinct technical features on the front display had varied effects on perceived usefulness, ease of use, and fit. Notably, the presence of activity tracking, alarm, and calendar functionalities led to distinct differences in ease of use and fit. Features such as distance tracking, phone call, social media notifications, text messaging, and time display functions showed significant influences on the perception of fit. These findings provide insights into the physical values of smart wristbands and smartwatches as perceived by users.
