Scientific analysis are carried on gilded ornamental shoes, which have been excavated from tomb No 1. and No 4. in Beopcheon-ri, Wonju dated from Baekje Period. This object is a very important because it provides valuable information on the development of metal-making techniques of that period. Thus, this article illustrates the investigation conducted to reveal how the object was created using what materials and techniques. Instead of the spikes-attached to the bottom plate of the object-that couldn't be sampled, a sample of a decorative rivet showing a similar structure to the spikes-attached to the other parts of the shoes-was prepared for a cross-section examination. Using radiography and microscopes, it was found that the head of a spike was placed and then punched to the gilded plate, so it can be held to the shoes. Under the SEM-EDS, the cross-section of the rivet shows that the gilding layer was applied before the attachment of the rivets. It also shows that the gilding layer is distributed unevenly and there are empty spaces indicating amalgam gilding was employed. This was confirmed as Mercury was detected on the SEM-EDS analysis of the object. The examination of the microstructure of the plate using the SEM-EDS revealed that the object is made of a single copper alloy plate with recrystallized twining and non-metallic white inclusions, which found to be lead in this case.

The Stone Lamp from Hyeon Hwa Temple is an important piece of buddhist art from the Koryo Dynasty (initiated by King Hyun-Joung). It provides an insight into stone-art techniques employed during the Koryo Dynasty, and serves as an authentic example of work from that period, which had both a refined style and artistic integrity. However, the stone lamp was dismantled and has been stored at the National Museum of Korea since 1986. This was because it was severely damaged, as a result of exposure to an outdoors environment. This article discusses the conservation of the stone lamp, which was carried out by conservators at the National Museum of Korea. It was prepared for a new display of the lamp to the public. The conservation process can be briefly described as follows: Cleaning (this includes the removal of previous repairs that were made), the re-attachment of the object's original fragments, and the gap-filling of missing parts. After its conservation, the object is in a much better condition and ready to be displayed once more. What is more important, in terms of the long term preservation of the stone lamp, is that the condition of the stone lamp needs to be continuously monitored, and appropriate conservation actions should be taken as necessary.

This research proposes measuring of BCG(ballistocardiogram) to monitor heart activities in a non-constrained environment, at home or work. Unlike with ECG, measuring BCG does not require the attachment of leads on the subject's body and allows signal measuring in a non-constrained state. It enables effective long-term monitoring of cardiac conditions. In this study a chair type BCG measurement system to continuous monitor the activity of the heart is implemented. The instrument consists of upper petal and ready for press of chair load cell sensor is attached to measure the change of the object's weight. In order to extract the output ballistic signal from the weight and force sensor signals. Beside the signal processing circuit for the digital conversion, the ballistic signal is detected using DAQ equipment. Signal processing algorithm including wavelet transforms for noise cancellation, template matching for normalization and peak detection in BCG is developed. ECG and BCG were concurrently measured to evaluate the performance of the system, and comparing the characteristics of the two signals verified the possibility of the system in non-constrained and nonconscious health monitoring.

Dynamic behaviour of beam carrying masses has attracted attention of many researchers and engineers. Many studies on the analytical solution of beam with concentric tip mass have been published. However, there are limited works on vibration analysis of beam with an eccentric three dimensional object. In this case, bending and torsional deformations of beam are coupled due to the boundary conditions. Analytical solution of equations of motion of the system is complicated and lengthy. Therefore, in this study, Differential Transform Method (DTM) is applied to solve the relevant equations. First, the Timoshenko beam with 3D tip attachment whose centre of gravity is not coincident with beam end point is considered. The beam is assumed to undergo bending in two orthogonal planes and torsional deformation about beam axis. Using Hamilton's principle the equations of motion of the system along with the possible boundary conditions are derived. Later DTM is applied to obtain natural frequencies and mode shapes of the system. According to the relevant literature DTM has not been applied to such a system so far. Moreover, the problem is modelled by Ansys, the well-known finite element method, and impact test is applied to extract experimental modal data. Comparing DTM results with finite element and experimental results it is concluded that the proposed approach produces accurate results.

The paper demonstrates the potential contribution of integrating discursive and affective analytic regimes in framing the study of Southeast Asia. I examine the "emotional possibilities" available to migrants with particular focus on the experience of Filipino domestic helpers in Hong Kong thrown into relief in 2016 by news of maids falling to their deaths while cleaning windows of their employers' above-ground apartments. First, I situate the study in recent calls for Critical Discourse Studies and Migration Studies to transcend foundational methodologies in their respective fields in order to apprehend formerly disregarded aspects of the human condition, including affect and emotion. I then briefly present the debate in the affective turn in social analysis, which has to do with rethinking the attachment of affect and discourse. My own inquiry is premised on the assertion that emotion is multidimensional. I specifically explore the usefulness of taking emotion as "affective-discursive practice" by focusing on an analysis of the appropriation of the victim role by foreign domestic helper employer groups that could be seen in pertinent news reports of selected online Hong Kong newspapers. In the end, I also emphasize the necessity of reflexivity in projects that take affect as central object of inquiry.

This study was aimed to compare and investigate the difference of academic self-concept and social self-concept between multicultural children and general children. The data were collected from a total of 285 multicultural children and 223 general children in elementary school, during three months from February 20, 2014 to May 20, 2014. Collected data were analyzed using t-test, Pearson correlation coefficients, and enter multiple regression with the SPSS 23.0 program. Multicultural children showed lower scores in academic and social self-concept, parents attachment, social support, and school life adaptation than general children. And their mental health level was lower than the general children. The study results were that academic self-concept of multicultural children was influenced by learning activity (${\beta}$=.298), social maladaptation (${\beta}$=-.218), communication (${\beta}$=-.196), and confidence (${\beta}$=.167), which explained for 42.4% of academic self-concept. Social self-concept of multicultural children was influenced by support from friend (${\beta}$=.285), peer relation(${\beta}$=.187), social maladaptation (${\beta}$=-.172), and depression (${\beta}$=-.139). which explained for 46.3% of social self-concept. Since the influence factors of academic and social self-concept of general children and multicultural children have a great power of explanation, they can be used for the intervention program enhancing self-concept for school aged children.

In this study, we examined the direction of the elderly education to improve the quality of life in the intelligence information society on the basis of the wisdom shown in the "Pan-jo wu-chih lun" of Seng-Zhao. The characteristics of the elderly in the intelligence information society are four-fold. First, the elderly show no deterioration in wisdom. Second, they have a lot of leisure time. Third, they are likely not to adapt in a rapidly changing society. Fourth, they are exposed to an economically vulnerable environment. But in the intelligence information society, the elderly cannot avoid death, and it is difficult for them to have insight into their existence due to the egotism, they take the attitude of attaching themselves only to exiting things. The direction of the Elderly Education to solve the problem is as follows: First, "Learning to know that Life-and-Death-and-suffering is temporary" is to make the elderly aware that the coming mind and the disappearing mind for a specific object are temporary and S?nya. Second, "Learning to be while eliminating the egotism" is set them free from the dogmatism that there is the attan. Third, "Learning to do to break the attachment" is to disabuse them of the idea that things will turn out according to their expectation through an awakening and to transforming their behavior.

The purpose of this study is to provide ideas for the development of bag design by analyzing the expression types and aesthetic formativeness of modern bag design using tassels and fringe given the newtro trend pursuing analog sensitivity in modern society. The methods and scope of this study are as follows. First, the related literature and internet data were reviewed in order to examine the expression types and characteristics of the bags of the West and East. Next, the definition and characteristics of tassel and fringe decoration in terms of the history of clothing were analyzed. Finally, the expression types and aesthetic formativeness of tassels and fringe were derived through the analysis of modern bag design shown in the fashion collections since 2010. The bags decorated with the tassels and fringe bring a variety of visual effects depending on the attachment position, direction and material composition, concentrating the gaze and radiating original style. In this study, the expression of tassels and fringe in modern bag design was classified into three types: surface decoration, shape variability, and object combination. Next, the aesthetic formativeness of modern bag design using tassels and fringe as decorative elements appeared through the mixture of heterogeneous materials and playfulness through imagination, exaggeration through extension of length and volume, and retro characteristics through reinterpretation of tradition. This study is expected to contribute to creative ideas of modern bag design which requires a global sense, which has been used in various cultures for a long time.
