In the 21st century, the development of technology overturned the paradigm of the entire society and culture, and the term 'high-tech' became generally accepted around the world by the momentous advances of technology. The purpose of this study is to define the concept of high-tech fashion by clarifying the characteristics of high-tech fashion, and to propose the proper approach toward the coming fashion. Hussein Chalayan shows the experimental and futuristic designs based on the cultural context of architecture and sculpture. Moreover, the scope of this study has been limited into Hussein Chalayan's recent works after the year 2000 up to 2007. High-tech architecture has been, in some ways, a response to pow technology a new aesthetic in contrast with standard modern architecture. High-tech architecture aimed to achieve a new industrial aesthetic, spurred on by the renewed faith in the progression of technology. However, no matter how prominent the industrial look appeared, the functional element of modern architecture has been very much retained. The characteristics of high-tech architecture that had been extracted by analyzing the antecedent studies were: technocism, transformability, and dynamism. Furthermore, the characteristics of high-tech fashion has been explained based on the characteristics of high-tech architecture. First, technocism is expressed either by the new technologized materials, and advanced digital technology. Second, transformability is expressed in the transformable clothing, which performs various functions. Third, dynamism is displayed in dynamic forms influenced by the technology of engineering. High-tech will be the dominant influence in fashion, and the designers will be enamored with the technologies of the new millenium. Architecture and fashion share the characteristics of high-tech, and their common cultural features is confirmed again.

This study examines the relationship between dynamic capabilities and operational capabilities as well as investigates the effect of these capabilities and performance. We also test these relationships on two industry groups categorized into high-tech industries and low-tech industries. We collected 221 firms' data from a questionnaire survey of small and medium-sized enterprises in Korea. Empirical results show that dynamic capabilities and operational capabilities influence performance positively. In high-tech industries dynamic capabilities directly affect performance while marketing capabilities appear to mediate the relationship between dynamic capabilities and performance. Dynamic capabilities show no significant effect on performance for low-tech industries; however, operational capabilities do mediate the relationship between dynamic capabilities and performance.

Hollow copper oxide/multi-walled carbon nanotubes (CuO/MWCNT) composites were fabricated via an optimized infiltration-reduction-oxidation method, which is more facile and easy to control. The crystalline structure and morphology were characterized by X-ray diffraction (XRD), and transmission electron microscopy (TEM). The as-prepared CuO/MWCNT composites deliver an initial capacity of 612.3 mAh·g^-1 and with 80% capacity retention (488.2 mAh·g^-1) after 100 cycles at a current rate of 0.2 A·g^-1. The enhanced electrochemical performance is ascribed to the better electrical conductivity of MWCNT, the hollow structure of CuO particles, and the flexible structure of the CuO/MWCNT composites.

An antenna-coupled bolometer-type terahertz sensor was designed, fabricated, evaluated, and utilized to obtain terahertz transmission images. The sensor consists of a thin film bowtie antenna that resonates accordingly in response to an incident terahertz beam, a heater that converts the applied current in the antenna into heat, and a microbolometer that converts the rise in temperature into a change in resistance. The device is fabricated by a bulk micromachining process on a 4-inch silicon wafer. The fabricated sensor chip has a size of $2{\times}2mm$ and an active area of $0.1{\times}0.1mm^2$. The temperature coefficient of resistance (TCR) of the bolometer film (VOx) is 2.0%, which is acceptable for bolometer applications. The output sensor signal is proportional to the power of the incident terahertz beam. Transmission images were obtained with a 2-axis scanning imaging system that contained the sensor. The small active area of the sensor will enable the development of highly sensitive focal plane array sensors in terahertz imaging cameras in the future.

The use of human resources determines the success of enterprises. This study applies the questionnaire design method to analyze the relationship between job stress, job satisfaction, and job performance, noting that few studies have comparatively examined these variables between industries, especially between high-tech and traditional industries. The proposed assessment model in this study can facilitate decision-makers' ability to make the optimal business decisions through their personnel systems, thereby improving employee satisfaction and increasing job performance. This study found that in the traditional and high-tech industries, some demographic variables have significant differences in the job stress, job satisfaction and job performance, but the demographic variables that can significantly affect the differences in these job's variables are differences between industries. This study acknowledges that job stress and performance have a significantly negative correlation, and traditional industries will have more stress factors than high-tech industries. In addition, support for traditional industries exist in job satisfaction and performance has a significantly positive correlation, but not in high-tech industries. Job stress for performance has a significantly negative correlation in two industries. This study reconfirmed the relationship between job stress, satisfaction and performance, found some differences in this relationship and the respective industrial characteristics.
