The purpose of this study was to examine the development trend of smart fiber by textile companies in Daegu/North Gyeongsang Province. This examination includes the development fields of smart fiber, investment size, information sources and the use degree of those, research-related infrastructure, relationship between companies' characteristics and their interests in smart fiber. Research data were collected by a survey. The definition and classification(4 areas and 12 development products) of smart fiber followed ones of Smart Fiber Technology Roadmap by the Ministry of Commerce, Industry and Energy. Data were analyzed using SPSS 11.0 program for frequency, means, t-test, and $X^2$-test. Among respondents, the numbers of dying and finish companies and export traders were the highest. It revealed that 19.6% of companies were developing smart fibers. Within 12 development products, vapor permeable/waterproof fiber showed to be most being developed, while medical fiber for human has not been developed and wasn't made an investment plan for developing. It was discovered that the biggest problem of smart fiber development was the lack of experts and the best outcome of smart fiber development was preoccupation of future market. It showed that companies got information from textile fairs but didn't often use information sources. The companies appeared to have a weak intention about research of smart fiber. The more important a company considered functionality of textile products and the more innovative and stabler the company was, the higher interest in smart fiber companies had. It was concluded that textile companies in Daegu/North Gyeongsang Province were aware of the importance of smart fiber development but they were not strongly interested in it and not enthusiastic in taking action on it.

The purpose of this study is to guide the research direction for securing the competitiveness of the textile industry by analyzing the trends of patent technology development for flexible materials and platform technologies of domestic and overseas textiles used for wearable devices. The study is based on patents from Korea (KIPO), USA (USPTO), Japan (JPO), Europe (EPO), PCT (WO), and China (SIPO), which were registered as of December 31, 2017. The analysis utilized 3,643 patents acquired from the WINTELIPS search DB. The technology classification system for patent analysis was divided into evangelist-based textile technology developments: human body (AA), fiber attachment patch development (AB), and service platform development (AC). The analysis findings are as follows: 1. The development of flexible materials and platform technologies for textile-based wearable devices has increased since 2000. In particular, China (SIPO) had the most patents. 2. In China, Japan, and Korea, most patent applicants are applied for by natives, but the US has a high proportion of foreigners applying for patents. 3. As for the amount of development of the evangelist-based textile technology (AA) was the most common with 1,203 (33%) cases. As a result of the above IP historical analysis, it can be seen that as a result of the global competition, domestic companies need to acquire IRP and standard technology, and promote commercialization by applying their products to smart wearables devices and other products.

If a research trend present in and outside the country is often seen, the structure measurement method of having used PZT and the optical fiber (FBG) will be the actual condition which has accomplished the stock. In order to manage such cracks, time, efforts and expense are required. Such a method has many difficulties in application of a structure by the difficult problem of the measurement range, and the expensive sensor price. Progressive cracks were generated by fracture of glass pipe sensor. Moreover, the experiment which can detect damage propriety by external Light Emitting Diode by damaging a glass pipe by load change with the application of switch using strain gage of a glass pipe was conducted.
