This article has significance in that it examines origin and developments of Baekje costume based on the validity of the reference material that can be used to infer the look of Baekje costume. On the basis of literature documents in Korea and China the shapes of it are examined, and the reliability of contents recorded in the sources is lexically reviewed. Errors related with features of the Baekje costume is minimized by investigating controversial issues in terms of periods and some parts which cannot be identified as the shapes of it. The changing aspects of the Baekje costume by flow of time can be observed based on various records in the literatures. The origin of it can be found in records regarding the costumes of Mahan and Buyeo. Baekje inherited the separate-type of costume structure from before the period of it, and possessed superior weaving technology. In the 3th century, the Baekje costume seemed to be established, and gradually developed from 4th to 5th century. As it continued to be developed, its frame was accomplished at the late 6th century. The shapes of it appeared to be further elaborated, specified, and therefore systematized in the 7th century.

This study is a discussion of the expressive characteristics of contemporary fashion design with floral images. It aims to help understand the overall trends of contemporary fashion design and textile motif design and expand the potential expression fields of originative design to natural objects such as flowers. Methodologically the study analyzed 976 pieces of data gathered from Haute Couture and Pr$\hat{e}$t-$\grave{a}$-Porter collections of 2005S/S-2009F/W, according to their types of expression. The study results show a share of 42.7% for plane type expressions by printing or weaving and a share of 51.5% for relief type expressions, compared with 5.7% for solid type expressions. However, those expressions represented elegant femininity with emphasis on formative beauty and were applied to fashion accessories or hair adornments. The expressive characteristics found from the analysis were represented by natural images, feminine elegance, and decorative aesthetics of handicrafts. Flowers in the contemporary fashion purify the internal emotions of humankind stand for personality and beauty in many different ways of expression and serve as a means of expressing more artistic values breaking out of stereotype.

Currently smart textile market is rapidly expanding and the demand is increasing integration of an electronic fiber circuit. The garments are an attractive platform for wearable device. This is one of the integration techniques, which consists of is the selective introduction of conductive yarns into the fabric through knitting, weaving or embroidering. The aim of this work is to develop a golf bend driven prototype design for an attachable Arduino that can be used to assess elbow motion. The process begins with the development of a wearable device technique that uses conductive yarn and flex sensor for measurement of elbow bending movements. Also this paper describes and discusses resistance value of zigzag embroidery of the conductive yarns on the tensile properties of the fabrics. Furthermore, by forming a circuit using an Arduino and flex sensor the prototype was created with an assistance band for golf posture training. This study provides valuable information to those interested in the future directions of the smart fashion industry.

The fouling of Nanofiltration membrane (NF) was examined using wastewater containing reactive black dye RB5 of 1500 Pt/Co color concentrations with 16890 mg/l TDS collected from El-alamia Company for Dying and Weaving in Egypt. The NF-unit was operated at constant pressure of 10 bars, temperature of 25℃, and flowrate of 420 L/min. SEM, EDX, and FTIR were used for fouling characterization. Using the ROIFA-4 program, the total inorganic fouling load was 1.07 mM/kg present as 49.3% Carbonates, 10.1% Sulfates, 37.2% Silicates, 37.2% Phosphates, and 0.93% Iron oxides. The permeate flux, recovery, salt rejection and mass transfer coefficients of the dye molecules were reduced significantly after fouling. The results clearly demonstrate that the fouling had detrimental effect on membrane performance in dye removal, as indicated by a sharp decrease in permeate flux and dye recovery 68%. The dye mass transfer coefficient was dropped dramatically by 34%, and the salt permeability increased by 14%. In this study, all the properties of the membrane used and the fouling that caused its poor condition are identified. Another study was conducted to regeneration fouled membrane again by chemical methods in another article (Abdel-Fatah et al. 2017).

Loosely coupled properties of SOA(Service Oriented Architecture) services do not guarantee that service applications always work properly. Service errors may also influence other services of SOA. These characteristics adversely affect software reliability. Therefore, it is a challenge to effectively manage system change and errors for operating services normally. In this study, we propose a SOA based framework using AOP(Aspect Oriented Programming) for reliable service applications. AOP provides a way to manipulate cross-cutting concerns such as logging, security and reliability and these concerns can be added to applications through weaving process. We define a service specification and an aspect specification for this framework. This framework also includes service provider, requester, repository, platform, manager, and aspect weaver to handle changes and exceptions of applications. Independent Exception Handler is stored to exhibited external Aspect Service Repository. When exception happened, Exception Handler is linked dynamically according to aspect rule that is defined in aspect specification and offer function that handle exception alternate suitable service in systematic error situation. By separating cross-cutting concerns independently, we expect that developer can concentrate on core service implementation and reusability, understanding, maintainability increase. Finally, we have implemented a prototype system to demonstrate the feasibility of our framework in case study.

An automatic welding equipment for thick plates requires the capability of the seam tracking of the weld line which often includes misalignment of the workpiece and variation of groove width. In this study, an automatic welding equipment and control algorithms based on the arc sensor were proposed for the GMA welding of thick plates which had misalignment and gap variation. The developed system being constituted with 5 axis can be automatically controlled by computer and also automnatically set the welding conditions such as welding current, and voltage. The proposed algorithms for the seam tracking in multi-pass welding of the thick plates were constituted as follows : the detection of weaving-end point for findng the variation of groove width, the control of welding velocity for acquiring a constant thickness deposition of weld metal, and the calculation of groove width and height of an arbitrary pass in the multi-pass weld. As results of the application of the system, it was revealed that the system had a good capability in seam tracking and made an excellent weld quality in V groove butt joint.
