The video deflectometer based on digital image correlation is a non-contacting optical measurement method which has become a useful tool for characterization of the vertical deflections of large structures. In this study, a novel imaging model has been established which considers the variations of pitch angles in the full image. The new model allows deflection measurement at a wide working distance with high accuracy. A monocular video deflectometer has been accordingly developed with an inclination sensor, which facilitates dynamic determination of the orientations and rotation of the optical axis of the camera. This layout has advantages over the video deflectometers based on theodolites with respect to convenience. Experiments have been presented to show the accuracy of the new imaging model and the performance of the monocular video deflectometer in outdoor applications. Finally, this equipment has been applied to the measurement of the vertical deflection of Yingwuzhou Yangtze River Bridge in real time at a distance of hundreds of meters. The results show good agreement with the embedded GPS outputs.

Understanding teachers in the early childhood education is crucial as it can not only affect the quality of children's education but also cause many critical problems such as child abuse. A significant amount of research work has been made on the use of robots in childcare classrooms. The finding from the research has shown many advantages such as the improvement of learning performance, social/emotional skills, creativity, concentration period, physical and cognitive development. However, most of the study has been implemented at the K-12 classrooms but not much has been focused on the education at the early childhood classrooms. Importantly, it is very crucial to understand teachers' perception, demands and technical competence about the new teaching tool, in order to maximize its educational effect. This paper investigates some critical issues existing in both teaching and managing in the early childhood education. It will also explore teachers' perceptions and expectations on the use of robots to identify some dilemmas that exist in their working and teaching environment. A survey study was conducted with 119 early childhood educators in South Korea. It analyzed the educators' perception of using robots to improve their teaching performance and to make better outcomes for children, investigated job satisfaction and difficulties that they have in the current work environment. This paper concludes with several guidelines for integrating and setting robotics in the early childhood environment, in order to engender productive outcomes for the future early childhood education.

Motor pumps cannot be used in those areas where electricity is not accessible such as remote rural areas in many African countries. Hydraulic ram pump is one of the solutions for supplying water for irrigation or domestic uses. The hydraulic ram pumps are working based on the water hammer effect for pumping without external power or electricity. This study was conducted to investigate the effect of air chamber volume and operation parameters on the performance of the hydraulic ram pump which was assembled with common plumbing parts. The experimental results showed the volume of the air chamber did not affect the performance such as discharge rate and head. When drive heights were 1.7 and 2.35 m, the maximum discharge heads were up to 7 m and 10 m, respectively. When the air chamber volume was 1 L, discharge rates were 0.23 and 2.12 L/min under the drive heights of 1.7 and 2.35 m, respectively. The average energy efficiency of the hydraulic ram pump assembled in this study was about 60% for all the experimental conditions.

In this study, we investigated the necessity and limitations of music composition required in TV documentary by conducting in-depth interviews with 20 music directors currently working at Korean Broadcasting System (KBS). Our research has shown that composition of music is necessary. However, in reality, it is difficult to use the composed music due to problems such as time and cost of composing and trust in the music composer; so music libraries, film music, or other music are used instead of the composed music in many situations. However, at the time when companies like its rival Netflix are aware of the importance of sound, the impact of Netflix could lead to a decline in the quality of terrestrial TV, which could lead to a weakening of competitiveness. Recently, in the case of sound programs, the sales of secondary works are active due to "internet uploading using YouTube" or "exporting programs", but the sales have been hindered by restrictions on the use of copyrighted works. The music source of library is said to be the one whose copyright problem has been resolved. In this study, we show that the composed music is an ultimate alternative to TV documentaries, since the library music is sometimes suspended due to the situations of management companies.

This cross-sectional survey research carried out with the inquisitive agenda on satisfaction of the translation outcomes as performed by human translation and (machine translation) post-editing. The survey group consisted of 166 Korean translators primarily working with the English, Chinese, and Japanese languages. They were asked to rate the satisfactory level with accuracy, fluency, idiomatic expression, and terminology in the Richter's scale of four. The result reveals that human translation is more satisfactory than post-editing with respect to accuracy, but it is uneasy to assert that accuracy is unsatisfactory in post-editing. On the other hand, the Korean translators are less satisfied with fluency, idiomatic expression, and terminology than accuracy. It can be assumed that although human translation is more satisfactory than post-editing, the accuracy of post-editing seems to be more acknowledged than fluency, idiomatic expression, and terminology, which lead the translators to take the accuracy of raw machine-translation products and to go on to improve the fluency, idiomatic expression, and terminology. Nevertheless, Korean translators believe Korean idiomatic expressions cannot be satisfactorily produced in post-editing, while fluency and terminology can be improved in post-editing.

The purpose of this research is to investigate the mediating role of performance information use in the relationship between result-oriented culture and organizational performance. The data were collected from chief accountants and managers working in public-sector organizations in Vietnam. The analysis was based on the 197 completed questionnaires by using Partial Least Squares Structural Equation Modeling (PLS-SEM). For the test research model and hypotheses, the supporting tool is SmartPLS 3 software. Research findings show that result-oriented culture is positively associated with organizational performance, and that performance information use is a mediating mechanism that explains how a result-oriented culture leads to higher performance in public organizations. The findings of this study suggest that the results-oriented culture, not only directly improves organizational performance, but also indirectly does so by the use of performance information. This study provides evidence for theoretical understanding of the impact of result-oriented culture on the performance of public-sector organizations through performance information use, and suggests practical implications for public organizations in applying result-oriented culture to foster using performance measurement and improve organizational performance. In order to achieve good performance, public-sector organizations need to create and spread result-oriented culture and enhance the use of performance information for decision-making.

The paper aims to explain the influence of celebrity endorser on consumers' purchase intention, and explain the influence of brand perception on purchase decision in regard to the case of OPPO F-series and singer Son Tung MTP, in the Vietnamese context. Advertisement is regarded as the fastest and most effective communication method for brands to build an association and attract their target consumers. Among various types of communication tools, the use of celebrity endorsement is considerably growing owing to the explosion of social platforms. This study employs survey data from 258 people living and working in Ho Chi Minh City, Vietnam. Then, those data were used to analyze the general hypotheses by conducting research reviews based on foregoing investigations. The results from data analysis reveal that celebrity's physical attractiveness, credibility, popularity, expertise, match-up, and multiple endorsements all have positive impacts on purchase intention. The findings from this study would suggest that brands, in general, and smart-phone brands, in particular, should not only focus on these attributes to select a suitable brand endorser, but also need to predict some potential risks when utilizing celebrity endorsement. Finally, various implications and recommendations for further studies and marketers are also discussed.
