The number of cyclists is on the steady growing for leisure, sports and transportation with the increasing interest in health and environment. However, the number of cycling accidents is also increasing steadily due to the lack of safety awareness and regulations. Focusing on these issues, we propose and develop the smart LED cycling helmet in order to reduce a risk of cycling accident. To provide the motion information of the bicycle for others, we attach the LEDs on the helmet and control the LED lights using Arduino. The motion information is displayed on the LED helmet by using sensors of the smartphone. Communication between Arduino and the smartphone is performed through Bluetooth.

Spandex is a elastomeric fiber in which the-fiber-forming substance is a long chain polymer consisting of at least 85% segmented polyurethane. In the polyurethanes there are the additional oxygen atoms in the main chains of the molecule. The effect of these oxygen atoms is to make the molecule flexible. From a physical point of view, elasicity and recovery from stretch are the most important properties of polyurethane, so its use had now expanded into many knitting industry. In this paper, we wish to Test the effect of some finishing conditions on the quality of polyurethane.

현재 다운방한 용도에 사용되는 직물 트랜드는 경량화 및 박지화 추세에 있으며, 국내외 유명 브랜드에서 사용되는 스포츠웨어 직물소재의 대부분이 이러한 제품으로 판매가 이루어지고 있다. 현재, 국내외 다운방한용에 사용되는 원단은 겉감이외에 다운 세기방지용 안감직물을 사용하여 다운이 빠져나오지 않도록 하고 있음. 그러나, 최근 겉감으로 사용하여 다운이 세지 않고 매우 가벼우면서 Packable 원단개발이 요구되고 있을 뿐만 아니라, 다운방한직물에 요구되는 성능에 만족하거나 성능이 향상된 고기능 원단개발이 요구되고 있다. 이러한 다운방한용 직물은 다운의 내구성 및 지속성 측면에서 매우 많은 기능이 요구되고 있으며 현재 국내에서 사용하고 있는 다운방한용 직물은 다운커버직물을 사용하거나 코팅에 의해 다운세기 방지기능을 강제로 발현시키고 있다. 그러나 그 직물은 경량화 되어가고 있기 때문에 다운커버 직물을 사용하지 않으면서부터 다운이 세는 문제점, 그리고 공기투과 및 투습이 제대로 되지 못하는 기능성의 문제점, 경량화와 더불어 인열강력이 약하여 잘 찢어지는 문제점, 인열강력의 물리적 특성을 높이고자 코팅을 하게되면 기능성 및 감성이 더욱 나빠지는 문제점이 나타나게 되어 다운 방한용 직물은 큰 문제점이 되고 있다. 이에 겉감만으로도 다운방한용도에 적합한 고감성 및 기능성을 가진 경량직물 개발을 위해 고밀도 제직 및 설계 기술, 최종 염색가공 및 후가공 공정까지의 공정내(內) 간(間)연계기술을 연구하였다.

This study intended to develop a motorcycle safe vest that can be prepared against accidents by mounting a smart module (with built-in sensor) on the safe vest in order to emphasize safety among functional aspects of the motorcycle clothing. The research method investigated professional books, prior research, and Internet data to examine the characteristics of motorcycle wear and the theoretical examination of smart wear, and analyzed the functional characteristics of the design by reviewing smart jacket and vest design cases for motorcycles currently on the market. As a results of study an interface device sensor, which contains a sensor with IMU(Intertial Measurement Unit) and CPU(Central Processing Unit), was inserted into a motorcycle top in order to draw attention to the safety of motorcycle riders. The IMU sensor attached to the vest detected the tilting motion of the rider to either left or right side to obtain data on left or right direction, sudden stop, and so forth and displayed left or right turn signal and sudden stop sign on the backplate (back) through the LED module. As for charging the device to operate LEDs, a generator, which is designed to convert the heat energy in the exhaust into electric energy, was used to efficiently self-produce the power required to operate LEDs of the top while riding.

This paper examined the garment formability and appearance of perspiration absorption, fast dry, and breathable fabrics. The mechanical properties and seam pucker properties of these fabrics were measured and regression analysis was conducted between fabric structural parameters and their mechanical and seam pucker properties. The superior total appearance value (TAV) of fast dry knitted fabrics for sports-wear was achieved in fabrics with high extensibility and bending rigidity; consequently, it increased with increasing stitch density and tightness factor. The formability of the fast dry knitted fabric also improved with an increasing stitch density and tightness factor. The seam pucker was influenced by bending rigidity and a good seam pucker was exhibited in the fast dry knitted fabrics with low stitch density and tightness factor. However, the formability (F) of the breathable fabric improved by increasing extensibility and bending rigidity that decreased with an increasing cover factor and the thickness of the breathable fabric. In addition, seam pucker deteriorated with an increasing cover factor and the thickness of the breathable fabric, which was similar to the results of the formability predicted in fabric mechanical properties. A superior seam pucker was achieved in fabrics with high extensibility and low bending rigidity.

Using Bernd H. Schmitt's experiential modules, this study investigated the effect of shopping value on recognizing the importance of customer experience. A survey was conducted with 400 adults aged in their 20s to 50s. To analyze the data, factor analysis, a reliability test, cluster analysis, and ANOVA were conducted. The results were as follows. First, the shopping values exhibited by sportswear consumers were a utilitarian shopping value and a hedonic shopping value. Through these, consumers were classified into four groups: a shopping value-oriented group, a utilitarian shopping value group, a shopping value-unconcern group, and a hedonic shopping value group. Second, the customer experience consisted of five factors: sensory experience, emotional experience, cognitive experience, behavioral experience, and relational experience. Third, a significant difference was observed in customers' perceived experiences according to shopping value type. In the shopping value-oriented group, all customer experiences were generally considered important, followed by the hedonic shopping value group and the shopping value-unconcern group, with the utilitarian shopping value group least likely to perceive customer experiences as important. In addition, cognitive and emotional experiences were rated highest among the five experiences, indicating that these were the most important store experiences among the various customer experience components.
