Speech recognition performance depends on various factors. One of the factors is the characteristic and established distance of a microphone which is used when speech data is collected. Thus, in the present experiment speech databases for tests are created through the type and established distance of a microphone. Then, acoustic models are built based on these databases, and each of the acoustic models is assessed by the data to determine recognition performance depending on various microphones and established microphone distances.

Established and new companies face similar business challenges in achieving performance and competitiveness. Furthermore, several empirical studies using competitive advantage resource-based view theory show that established companies achieve performance and competitiveness with breakthrough innovations. Similarly, new business ventures with limited resources must incorporate breakthrough innovations to achieve performance and competitiveness. Therefore, this study aimed to examine the impact of ambidextrous innovation on new venture performance and competitiveness. It used an online survey to collect data from 178 newly established shipping agency companies in 22 provinces in Indonesia. Data was analyzed using multivariate analysis with WarpPLS 7.0, where the analysis unit was an organization represented by a director. The results showed that ambidextrous innovation positively and significantly affects firm performance and new venture competitiveness. This means that ambidextrous innovation that emphasizes adaptation and development improves the firm's internal business processes, even with limited resources. Moreover, it increases new ventures' competitiveness in responding to threats and taking advantage of market opportunities. These results contribute to the competitive advantage resource-based view theory, specifically for new venture empirical examination. Also, they contribute to practical implications in the transportation business, demonstrating that exploitative breakthrough innovation can improve new venture competitiveness and performance.

The use of Hollow Structural Sections (HSS) provides an alternative for steel buildings in seismic zones, with the advantage over WF columns that the HSS columns have similar resistance along both axes and enhanced performance under flexure, compression and torsion with respect to other columns sections. The HSS columns have shown satisfactory performance under seismic loads, such as observed in buildings with steel moment frames in the Honshu earthquake (2011). The purpose of this research is to propose a new moment connection, EP-HSS ("End-plate to Hollow Structural Section"), using a wide flange beam and HSS column where the end plate falls outside the range of prequalification established in the ANSI/AISC 358-10 Specification, as an alternative to the traditional configuration of steel moment frames established in current codes. The connection was researched through analytical, numerical (FEM), and experimental studies. The results showed that the EP-HSS allowed the development of inelastic action on the beam only, avoiding stress concentrations in the column and developing significant energy dissipation. The experiments followed the qualification protocols established in the ANSI/AISC 341-10 Specification satisfying the required performance for highly ductile connections in seismic zones, thereby ensuring satisfactory performance under seismic actions without brittle failure mechanisms.

The issue of North Korea's denuclearization is an global issue that transcends the North and South. It is necessary to prepare for the denuclearization process in preparation for the situation in which North Korea reveals its intention to denuclearize. In the process of North Korea's denuclearization, it is required to guarantee the normal operation of the denuclearization verification equipment. If a performance test criteria that takes into account the North Korean environment is established, it is highly likely that it will be used in the future denuclearization process. For this purpose, basic materials related to performance test standards were established through analysis of test standards such as international standards. After that, we established a performance test criteria. This includes high temperature, low temperature, humidity, vibration and shock tests. Through follow-up studies, validity of test criteria will be established through actual device testing.

This paper aims to provide pragmatic application guidelines of the interior finish materials for apartment houses with newly-established evaluation methodology of the sustainable degree of interior products. With reference to the standards and criteria of domestic eco-labeling accreditation schemes for sustainable products in the area of architecture which focus on the sustainable elements classified as the health, recyclability, durability, and energy efficiency, in this study, a systematic evaluation method has been established for interior finish products with quantifiable indicators for sustainable performance. Base on the evaluation system introduced here, most interior finish products can be classified into a database and applied effectively to the realities from the perspective of the sustainability. There are the necessities of enforcement issues with the idea of revising or taking remedial measures of the current performance criteria of domestic eco-labeling accreditation to bolster their reliability. As well as already-commercialized products, hereafter, continued efforts are needed to control the whole process of manufacturing new interior finish products from their designing, constructing, consuming, recycling and to dismantling in terms of sustainability, which promises more pragmatic follow-up measures for the detail embodiment of the environment-friendly spaces.

Realization of electronics with performance equal to established technologies that use rigid semiconductor wafers, but in lightweight, foldable and stretchable formats would enable many new application possibilities. Examples include wearable systems for personal health monitoring, 'smart' surgical gloves with integrated electronics and electronic eye type imagers that incorporate focal plane arrays on hemispherical substrates. Circuits that use organic or certain classes of inorganic electronic materials on plastic or steel foil substrates can provide some degree of mechanical flexibility, but they cannot be folded or stretched. Also, with few exceptions such systems offer only modest electrical performance. In this talk, I will present a new approach to high performance, flexible and stretchable integrated circuits. These systems combine single-crystal silicon nanoribbons with thin plastic or elastomeric substrates using both "top-down" and "transfer-printing" technologies. The strategies represent promising routes to high performance, flexible and stretchable optoelectronic devices that can incorporate established, high performance inorganic electronic materials.

Purpose - This study aims to examine the effect of entrepreneurship of start-ups on export performance when the business closure rate is higher than business start-up rate in Korea. Thus, this study analyzes various factors for start-ups established within the past seven years and uses export performance as an indicator. Prior to analysis of factors, the study defines the concepts of start-up factors based on various studies. Design/methodology - In order to analyze the export performance of startups, this study conducted an empirical analysis using statistical analysis. Theories were established based on previous studies, and hypotheses and research models were designed based on the established theories. Subsequently, in order to verify the research hypothesis and research model, factor analysis such as validity and reliability, and structural equation modeling were analyzed. Findings - As a result of analysis based on previous studies, we found that there is a difference between theoretical and practical aspects. Whereas previous studies showed that market orientation, technology orientation, and social capital have a direct impact on export performance, the present study analyzed that there is no such impact, and that technology capabilities were important as a result of the unique traits of start-ups. Originality/value - Existing studies have limitations in understanding the overall characteristics of a company by using market orientation, technology orientation, and social capital as individual independent variables. In addition, the existing researches have been analyzed in relation to corporate performance, whereas this study has been limited to export performance, so it can be regarded as different from other studies.

It is a fact that domestic performance art has been sharply progressed but it is focused on only performance quality technique, not on safety of performers and the audience. It is a pity that people's effort to keep safe stage environment have not traced to innovative change, eventually leading to be forced to perform under hazardous condition. This study is to find out and identify that domestic regulation and accident cases are investigated and compared with cases of advanced countries, to verify that performer and the audience are main elements to develop performance art. And it is to show more effective safety measure after pointing out hazardous elements. Research change is limited to review only performance ones of all cultural facilities and to review accident cases from these places to show reasonable safety measures for stage facilities. Operation manager covers almost all of areas such as devices, management, despite a fact that they take charge of stage facilities, illumination, sounds, already. Some conclusions are as follows; 1) performance theatre-related regulations should be established again. domestic safety standards for performance theatre safety should be established. 2) characteristic and purpose of performance place should be clarified at the stage planning and design of them 3) operation expert performance place is required to be trained to cover emergency situation at any time.
