This paper provides an overview of the use of different Distributed Optical Fiber Sensor systems (DOFSs) to perform Structural Health Monitoring (SHM) in the specific case of civil engineering structures. Nowadays, there are several methods available for extracting distributed measurements from optical fiber, and their use have to be according with the aims of the SHM performance. The continuous-in-space data is the common advantage of the different DOFSs over other conventional health monitoring systems and, depending on the particular characteristics of each DOFS, a global and/or local health structural evaluation is possible with different accuracy. Firstly, the fundamentals of different DOFSs and their principal advantages and disadvantages are presented. Then, laboratory and field tests using different DOFSs systems to measure strain in structural elements and civil structures are presented and discussed. Finally, based on the current applications, conclusions and future trends of DOFSs in SHM in civil structures are proposed.

With semiconductor scaling approaching the physical limits, devices including CMOS (complementary metal-oxide-semiconductor) components have managed to overcome yet are currently struggling with several technical issues like short-channel effects. Evolving from the process node of 22 nm with FinFET (fin field effect transistor), state-of-the-art semiconductor technology has reached the 3 nm node with the GAA-FET (gate-all-around FET), which appropriately addresses the main issues of power, performance, and cost. Technical problems remain regarding the foundry of GAA-FET, and next-generation devices called post-GAA transistors have not yet been devised, except for the CFET (complementary FET). We introduce a CFET that spatially stacks p- and n-channel FETs on the same footprint and describe its structure and fabrication. Technical details like stacking of nanosheets, special spacers, hetero-epitaxy, and selective recess are more thoroughly reviewed than in similar articles on CFET fabrication.

This study was conducted to identify Korea's TRIZ research trends and to propose implications for setting a direction for future TRIZ research by analyzing TRIZ-related research over the past 15 years, or from 1998 to 2013. The subjects in this study were 256 published studies, including 149 studies in academic journals, 97 master theses, and 10 doctorate theses. This study reached the following conclusion. First, academic journals were the most frequent form of publication of TRIZ-related studies, followed by master's degree theses, and doctorate theses. Second, two or more TRIZ tools were used to solve problems and the most frequently used topic was technical contradiction as the result of frequency analysis for TRIZ research topics. This signified that it was easier to solve problems when various TRIZ tools were used, rather than applying a single TRIZ tool while technical contradiction was considered to be actively used as it allowed the relatively easy understanding of TRIZ. Third, the use of TRIZ research topics had increased and diversified each year. This could be interpreted to be based on the increased understanding of TRIZ. Fourth, case studies and experimental research were the most frequently used methods in TRIZ-related research. This was because various TRIZ tools were applied on problem solving situations, which were directly proposed as the research result. Fifth, the use of TRIZ was increasing in the educational field. Specifically, it was noted that TRIZ was used in creativity education with the use of 40 invention principles in elementary, middle, and high schools.

The purpose of this study was to investigate the fashion trends of last three years and how the trends were imaged by the structural characteristics of the fabrics. The characteristics for 897 fabrics were analyzed from four kinds. eleven volumes of fashion trend magazines. From these magazines, three panels categorized by their frequencies as nine images such as natural, innocent, ethnic, childish, casual, classic, modern and technical, Sub-images of each image such as rustic, irregular, decorative, etc were also categorized. For the each image, fiber contents and structural characteristics of weave type, weight, density, yarn size, twist and fabric finishes were investigated in terms of frequency, range and mean, Results showed that chiffon and organza seemed to have very specific images and used to represent specifically the romantic or ethnic images; whereas voile and jersey was used to represent various images. For S/S seasons, most popular fiber type was cotton. The weave type was not the important factor to give variations in images; plan weave exclusively used irrespective of image. For the romantic, ethnic and innocent images, rather light fabrics were used. For the childish and natural, medium weights, and for the technical, modern and classic images heavy weight fabrics were used. Vaious finishes were employed to represent specific images.

This paper examines the trends of recently developed human-care robots and social interaction technologies. As one of the solutions to the problems of an aging society, human-care robots have gained considerable attention from the public and the market. However, commercialized human-care robots do not meet user expectations for the role as companions. Current robot services based on short-term interaction and fragmentary pieces of intelligence have encountered difficulty in eliciting natural communication with humans. This results in the failure of human-robot social bonding. Social interaction is being actively investigated as a technique for improving robots' natural communication skills. Robots can form a natural bond with humans through social interaction, which consequently increases their effectiveness. In this paper, we introduce recent human-care robot-related issues and subsequently describe technical challenges and implications for the success of human-care robots. In addition, we review recent trends on social interaction technologies and the datasets required.
