The metals present in atmospheric particulate come from various sources; natural or anthropogenic. Among various metals Fe, Zn, Pb, Cu, and Mn are of particular concern in as much as they are not only present in large quantity, but toxic to human body. A simple, fast, and non-destructive analytical method for these metals in atmospheric particulate was developed and the analytical details were described herein. The method involves the measurements of X-ray fluorescence of sample contained in filters and comparing it with those for standards. The standard filters were prepared by applicating premeasured standard solution to the filters and then drying. The accuracy of the method was tested by analyzing standard reference materials and by independently analyzing samples using a different, previously accuracy-proven method, inductively coupled plasma atomic emission spectrometry, and comparing the results obtained. Analytical sensitivities and detection limits of the present method were 62.9, 178.2, 82.9, 146.1, 37.2, 120.3 cps/$\mug/cm^2$ and 39.0 35.6, 137.5, 125.9, 182.6, 72.8 $ng/cm^2$ for Fe, Zn, Pb, Cu, Mn, and Ni respectively. The method was applied to Seoul atmospheric particulate and some results were reported.

The purpose of this research is to provide useable data for application in American and Korean apparel company. This data was developed by analyzing information of Korean and American body sizes obtained from "Size USA Project" and "Size Korea Project". The Subjects were 6,306 American females and 1,988 Korean females over 18 years old. 30 measurements and 14 computed values were chosen that were considered critical in making garments. And descriptive analysis, percentile analysis and t-test were used as statistical methods for analyzing measurements and computed value between the two countries. The results were as follows. It was determined that American women were larger and bigger than Korean women in all measurements and computed values, except for Shoulder Slope. Based on BMI values, we determined that American women had a distinct tendency towards being overweight. Through the comparison of drop values (i.e. the difference between Hip and Bust Girths or Hip and Waist Girths), ratio values (i.e. waist height divided by height) and Body Mass Index (BMI) between the two countries, we determined that American women's figures were shapelier than Korean women's. American women had higher hip heights and longer leg lengths for their height compared to Korean woman. Furthermore, the back shapes of Korean women were flatter than American women and BMI values indicated American women were relatively more overweight than Korean women.

Affective aspects of design attributes such as color, Pattern, and texture are important to the overall impression and the success of interior products. Among all the interior materials, wallpapers and flooring materials take up largest construction area and they are main components in creating affective impression for customers. This study aims to investigate the relationship between luxuriousness and related affective variables and design elements of wallpapers and flooring materials. The approach consists of 3 steps: (1) selecting related affective features and product design attributes through a literature survey, opinion of expert panel, and focus group interview, (2) conducting evaluation experiments, and (3) developing Kansei models using multivariate statistical analysis and analyzing critical attributes. Evaluation experiment was conducted using a questionnaire made up of 7-point scale and 100-point scale and 30 housewives and 20 interior designers participated in the evaluation experiment. The result of evaluation was analyzed through principal component regression and quantification I analysis. As a result of analyzing the survey data, the relationship between luxuriousness and related affective features and product design attributes was identified, moreover a optimal combination of the design component was identified. Consequently, it is expected that the results of the study would be a basis of the concept of emotion-based design by giving insights about how customers perceive the luxuriousness and suggesting the optimal combination, and providing specific quantitative design guidelines.

A three-dimensional; structural health monitoring; vertical; planar; cross-sample entropy; multiscaleA three-dimensional structural health monitoring (SHM) system based on multiscale entropy (MSE) and multiscale cross-sample entropy (MSCE) is proposed in this paper. The damage condition of a structure is rapidly screened through MSE analysis by measuring the ambient vibration signal on the roof of the structure. Subsequently, the vertical damage location is evaluated by analyzing individual signals on different floors through vertical MSCE analysis. The results are quantified using the vertical damage index (DI). Planar MSCE analysis is applied to detect the damage orientation of damaged floors by analyzing the biaxial signals in four directions on each damaged floor. The results are physically quantified using the planar DI. With progressive vertical and planar analysis methods, the damaged floors and damage locations can be accurately and efficiently diagnosed. To demonstrate the performance of the proposed system, performance evaluation was conducted on a three-dimensional seven-story steel structure. According to the results, the damage condition and elevation were reliably detected. Moreover, the damage location was efficiently quantified by the DI. Average accuracy rates of 93% (vertical) and 91% (planar) were achieved through the proposed DI method. A reference measurement of the current stage can initially launch the SHM system; therefore, structural damage can be reliably detected after major earthquakes.

Animal glue has been used as a binder in Dancheong since the Joseon dynasty. Binders play an important role in determining the physical characteristics of a painting layer. The analysis of binders can be used to identify the materials and techniques used in traditional Dancheong. Binders can be investigated using physicochemical component analyses methods such as gas chromatography/mass spectrometry, pyrolysis-gas chromatography/mass spectrometry, and fourier transform infrared spectroscopy, but the detection characteristics vary depending on the degradation properties of the pigment and binder. Therefore, cross-validation using a combination of physicochemical analysis and enzyme immunoassay is used to increase the reliability of the results. In this study, we present an enzyme-linked immunosorbent assay (ELISA) as an example of an enzyme immunoassay as a method for analyzing animal glue, a traditional binder used in Korea. The applicability of ELISA was tested using commercial animal glue, in addition to animal glue produced using a variety of extraction conditions. The animal glue was analyzed in a Noerok-additionally coated-replica sample to evaluate the possibility of analyzing the animal glue in a paint layer mixed with pigment. Based on the results, we performed an assay on the use of animal glue in the Dancheong sample of the temples of the Joseon dynasty, that are estimated to have been built in the 17^th century.

The volume of transfer passengers now faces a crisis because the number of Chinese and Japanese passengers, the majority of transfer through Korea, is decreasing. This paper is analyzing the their air travel behaviors as well as characteristics of their transfer behaviors at airport. According to the research, it is suggested that transfer passengers perceive the importance of duty-free stores but their satisfaction of using duty-free stores during their transfer at Icheon airport was proven to be low. Considering the characteristics of transfer service quality at Incheon airport, waiting time of transfer is important but not satisfactory for them. Moreover, information of free transfer tour to city downtown and paid-in transfer tour for medical tourism is not known very well among North East Asian passengers. Thus, it is necessary to do detailed research of North East Asian transfer passengers, who have transferred through Incheon airport more than twice a year, to find out their exact needs of transfer tour in Korea.
