Effects of water-misting sprays with forced ventilation after transport during summer on meat quality, stress parameters, glycolytic potential and microstructures of muscle in broilers were investigated. A total of 105 mixed-sex Arbor Acres broilers were divided into three treatment groups: i) 45-min transport without rest (T group), ii) 45-min transport with 1-h rest (TR group), iii) 45-min transport with 15-min water-misting sprays with forced ventilation and 45-min rest (TWFR group). The results showed the TWFR group significantly increased (p<0.05) initial muscle pH ($pH_i$) and ultimate pH ($pH_u$) and significantly reduced $L^*$ (p<0.05), drip loss, cook loss, creatine kinase, lactate dehydrogenase activity, plasma glucose content, lactate and glycolytic potential when compared with other groups. Microstructure of the muscle from TWFR group broilers under light microscopy showed smaller intercellular spaces among muscle fibers and bundles compared with T group. In conclusion this study indicated water-misting sprays with forced ventilation after transport could relieve the stress caused by transport under high temperature, which was favorable for the broilers' welfare. Furthermore, water-misting sprays with forced ventilation after transport slowed down the postmortem glycolysis rate and inhibited the occurrence of PSE-like meat in broilers. Although rest after transport could also improve the meat quality, the effect was not as significant as water-misting sprays with forced ventilation after transport.

Multiscattering occurs when a laser transmits into dense atmosphere targets (e.g. fogs, smoke or clouds), which can cause depolarization effects even though the scattering particles are spherical. In addition, multiscattering effects have additional information about microphysical properties of scatterers. Thus, multiscattering can be utilized to study the microphysical properties of the liquid water cloud. In this paper, a Monte Carlo method was used to simulate multi-scattering transmission properties of Lidar signals in the cloud. The results showed the slope of the degree of linear polarization (SLDLP) can be used to invert the extinction coefficient, and then the cloud effective size (CES) and the liquid water content (LWC) may be easily obtained by using the extinction coefficient and saturation of the degree of linear polarization (SADLP). Based on calculation results, a microphysical properties inversion method for a liquid cloud was presented. An innovative multiscattering polarization Lidar (MSPL) system was constructed to measure the LWC and CES of the liquid cloud, and a new method based on the polarization splitting ratio of the Polarization Beam Splitter (PBS) was developed to calibrate the polarization channels of MSPL. By analyzing the typical observation data of MSPL observation in the northern suburbs of Nanjing, China, the LWC and CES of the liquid water cloud were obtained. Comparisons between the results from the MSPL, MODIS and the Microwave radar data showed that, the microphysical properties of liquid cloud could be retrieved by combining our MSPL and the inversion method.

Intelligent robots are being introduced and utilized to create new values in diverse fields such as medical care, national defense, education, and manufacturing. However, while the technical aspects of intelligent robots are spreading, the business side is lacking in recognition. The purpose of this study is to identify the factors affecting product innovation through the introduction of intelligent robots in enterprises. Among the six variables secured from the technology, organization, and environment framework, only perceived direct usefulness and competitive pressure have significant effects on product innovation. The results imply that the effects of introducing robots are still in their early stage from a business perspective.

Purpose - This study investigates the relationship between firm-specific, general human capital and corporate innovation performance. Also, we examine when this relationship is more salient. Design/methodology/approach - We collected 1,195 survey data related to a sample of corporate innovation performance and human capital from 1) Korea Research for Vocational Education and Training and 2) NICE information service in Korea. In order to examine the corporate innovation performance, we use the ordered logit model. Findings - First, we find robust supports for our hypothesis that firm-specific and general human capital increase corporate innovation performance. Second, the effect of general human capital on corporate innovation performance is stronger when this relationship is combined with the firm international experience. Research implications or Originality - By integrating the human capital theory and corporate innovation literature, we propose that firm-specific and general human capital are the important determinant of innovation performance. The firm-specific human capital may increase innovation efficiencies. Also, retaining higher-quality general human capital is considered as an important innovation strategy since firms with higher-quality general human capital make greater innovation performance. Further, we show that the firm international experience is the crucial boundary condition. As a firm's experience in internationalization increases, firms can enhance the opportunities to develop new products by combining the skills and knowledge derived from general human capital with the experience gained through internationalization.

This research was conducted to assess the effects of an engineering education accreditation program devised by the University of Seoul on higher education outcomes by comparing and analyzing the evaluation results of engineering accredited students (31) and those who are not accredited (47) with the OECD AHELO (Assessment of Higher Education Learning Outcomes) in 2013. The AHELO assessment tool consisted of 25 multiple-choice questions which evaluated generic skill-learning outcomes, also using contextual surveys to establish the students' backgrounds. The results were evaluated statistically. In the results from the multiple-choice exam for generic skill learning outcomes, accredited students scored 1.35 points higher than non-accredited students. Secondly, according to the contextual survey related to students' university education experience, such as lectures, seminars, group projects, and online tutoring, it was found that accredited students were provided more activities in seminars and group projects. Moreover, for class activities, more of these were provided to accredited students, especially in the areas of assortment-structuralization and teamwork-based activities. Thirdly, according to the contextual survey results related to participation in class, specifically regarding asking questions and participating in discussions, interacting with the professor, and opportunities for study time, there were no recognizable differences between accredited and non-accredited students, However, while accredited students at least had opportunities to gain experience in most areas, there were some areas for which education resources were not provided to non-accredited students. Therefore, for the University of Seoul, our results imply that accredited students may show better performance in the areas of academic accomplishment and in their educational environment as compared to non-accredited students. These results demonstrate that the engineering education accreditation program positively contributes to employment competitiveness while also improving the necessary global standards of higher education outcomes.

The purpose of this descriptive correlational study was to explore the effect of knowledge of evidence-based practice (K-EBP) and organizational culture on the innovation behavior of university librarians in South Korea. The structured survey questionnaire consisted of four sections and 60 items. The four sections were concerned with K-EBP, organizational culture, innovation behavior, and EBP-related activities and demographic. The respondents were librarians working in 101 university libraries in South Korea. The results of this study were as follows. First, K-EBP indicated that the respondents had excellent practical skills, but their ability to appraise critically, apply knowledge and to conduct research was weak. Second, the questionnaire scores for K-EBP were significantly positively correlated with those for organizational culture and innovation behavior. Higher K-EBP scores corresponded to higher scores for relation-, innovation-, and task-oriented organizational culture. Third, K-EBP outcomes differed significantly by age group, education level, employment type, job title/seniority, reading of academic journal articles, and attendance at conferences. Organizational culture differed significantly with age. Innovation differed significantly with both age and conference attendance. Fourth, in the hierarchical multiple regression analysis, factors predicting K-EBP scores were education level and reading academic journals. Fifth, the multiple regression analysis identifying factors predicting innovation revealed statistically significant regression coefficients for overall K-EBP and for innovation- and hierarchy-oriented organizational culture. The regression coefficient for perception of a hierarchy-oriented organizational culture was negative. To promote innovation behavior of librarians, we need to foster an innovative organizational culture characterized by communication and cooperation, and improve the ability of librarians to engage in EBP. Educational programs that promote librarian engagement in research-related activities are needed.

This study aims to develop the scales to measure the innovation configurations of Science. Technology, Engineering, Art and Mathematics (STEAM) from the perspective of elementary school teachers and investigates the effect of the innovation configurations and related environmental factors on the usage levels of STEAM based on the newly developed scales for the innovation configurations of STEAM. The scales for the innovation configurations of STEAM are based on analyzing the various previous studies and in-depth interviews and consist of four sub-configurations: The 'Preparation,' 'Design,' 'Implementation,' and 'Evaluation.' The innovation configurations of STEAM was investigated with the developed scales through 266 teachers who are leading STEAM school teachers, are involved in STEAM research group, or are implementing STEAM in general schools. The final 19 questionnaires for the scale of the innovation configuration of STEAM are confirmed with exploratory factor analysis and reliability analysis. In order to examine the relationship between the innovation configurations and levels of use, the direct relationship between four sub-configurations and the usage levels of STEAM and the effect of environmental factors on the innovation configuration and the usage levels of STEAM have been conducted and their interactions are considered. The results show that 'Implementation' in the innovation configurations of STEAM and 'STEAM training experience' are most important factors to improve the usage levels of STEAM for elementary school teachers. It implies that the scales are very helpful in improving as well as figuring out the current innovation configurations of STEAM.

In Korea, engineering education based on industry demand is highly emphasized; the survey of industry demand or company satisfaction is frequently conducted. Although engineering schools have often attempted and implemented the reform of engineering education, it was found that company satisfaction with college education was always low. In this context, this study aimed to find the cause of the low satisfaction. To this end, the social background for the active survey of industry demand and company satisfaction, and its progress were investigated. The findings of this study showed that the survey of industry demand in Korea has limitations in improving the quality of college education or developing its future demand, contrary to its intention. This industry demand based approach has its historical and social root in the Korea-specific model of the catching-up style industry development and technology innovation. Therefore, it is difficult to establish appropriate academy-industry relations and discover future vision based on this model. This study presents a new way to understand and develop the future-oriented industrial and social demand, not just arguing for the uselessness of the survey of industry demand in engineering education.
