  • Compared with the research on consumer engagement in brand community, the research on consumer engagement in brand public has been relatively less. This research aimed at exploring how brand public characteristics such as information variety, various communications and no limitation in expressing self affect the brand public engagement. 274 questionnaires answered by Chinese consumers are used to conduct analysis. Principal component analysis is used to test the reliability and validity of each construct, and structural equation model is used to test hypotheses. The study finds the positive effects of information variety on information benefits, those of various communications on social benefits, and also positive roles of no limitation in expressing self to brand-related self-expression motivation. And each of the information benefits, social benefits and brand-related self-expression motivation is proved to positively affect brand public engagement. The study implies that marketers should give attention to characteristics of brand public, and provide the ways by which members of brand public engage the brand. Additionally, marketers should pay more attention to both direct and indirect engagement activities of consumers toward brand public in social media to better understand their target consumers.

  • Personalized product recommendation service is receiving attention as a new marketing strategy while supporting consumer information search and purchasing decisions. This study attempted to verify the effect of self-reference on service use behavior through the dual path of cognitive attitude and emotional attachment. Using convenience sampling, an online survey was conducted with 324 women who were in their 20s and 30s. After collecting and compiling the survey data, the reliability and validity of variables constituting the conceptual research model were verified through confirmatory factor analysis using AMOS 22.0. Next, the significance of sequentially mediated pathways was verified using Process 3.5 Model 80. The results showed that self-referencing not only significantly affects service use intention by simply mediating cognitive attitudes but also sequentially mediates cognitive attitudes and additional information search. Furthermore, self-referencing was significant as an indirect path to service use intention by mediating additional information search. However, in the path mediated by emotional attachment, self-referencing was considered as a simple mediated path leading to service usage intention. These results indicate a dual path in the psychological mechanism, through cognitive and emotional evaluation, that prompts consumer behavioral responses to the personalized product information provided in the shopping process.

  • This study aims to examine the role of training and absorptive capacity as a mediator to examine the impact of human capital dimensions on the performance of an organization. This study employs the quantitative approach for analysis. A sample of 208 respondents was collected from the textile factories based in Karachi and Faisalabad. Data was analyzed using the PLS-SEM technique. PLS-SEM algorithm was used to check the validity and reliability of the data. PLS-SEM bootstrapping was used for studying the impact. The results show that the skills have an insignificant impact on organizational performance. Education and skills have an insignificant indirect impact on the performance of an organization. The research findings show that the human capital dimensions are full and partially mediated via absorptive capacity and training. The findings revealed that if we implement one by one dimension of human capital then it will not cause any increase in the organization's performance but if we implement all dimensions then it results in optimal performance. Thus, this study suggests adopting effective training techniques and creating absorptive capacity in an organization to increase the performance of an organization. The findings of this study significantly contribute to the existing body of knowledge.

  • The radionuclide inventory in radioactive waste from nuclear power plants should be determined to secure the safety of final repositories. As an alternative to time-consuming, labor-intensive, and destructive radiochemical analysis, the indirect scaling factor (SF) method has been used to determine the concentrations of difficult-to-measure radionuclides. Despite its long history, the original SF methodology remains almost unchanged and now needs to be improved for advanced SF implementation. Intense public attention and interest have been strongly directed to the reliability of the procedures and data regarding repository safety since the first operation of the low- and intermediate-level radioactive waste disposal facility in Gyeongju, Korea. In this review, statistical methodologies for SF implementation are described and evaluated to achieve reasonable and advanced decision-making. The first part of this review begins with an overview of the current status of the scaling factor method and global experiences, including some specific statistical issues associated with SF implementation. In addition, this review aims to extend the applicability of SF to the characterization of large quantities of waste from the decommissioning of nuclear facilities.

  • 본 연구는 Brazilian 시험결과를 매개로 일축압축강도와 탄성계수를 추정할 수 있는 경험식을 화성암의 대부분을 구성하는 화강암, 안산암 및 유문암을 대상으로 도출하였다. 기존 간편식(점하중 강도지수, Schmidt hammer 타격법)으로 도출된 결과와 비교, 검정을 하여 좋은 상관성과 신뢰성을 확인하였기에 Brazilian 시험은 일축압축강도와 탄성계수를 추정할수 있는 또 하나의 간접방법으로 사료된다. 특히 지질 조사시 얻은 제한된 코어로 인하여 직접시험이 어려운 경우에도 본 연구에서 제시하는 방법이 효율성이 있을 것으로 사료된다.

  • For producing iron or steel products with good quality, the concentration of the material components should be analyzed quickly with high relability using XRF(Fluorescent X-Ray Spectrometer). Since the analysis results are much dependent upon the surface con- dition, the samples have to be prepared to have good test condition. This study presents an image processing system for inspecting the surface condition of the iron test sample. In order to use thd computer vision system, we need to develop a lighting device and image processing algorithm. For the adequate lighting device of inspection system, the indirect lighting device is contrived to cut the external light and provide uniform, stable and cold light. The image processing algorithm is aimed to reduce inspection time and to get similar analyzing results to those of the experienced operators. At first, the image processing algorithm checks whether the surface of the iron sample is ground well or not. Then, the defects; hole or dig are conted and surface condition is evaluated. In addition, the algorithm gives the reliability of the analyzing results in order to help operator's decision.

  • Objective: The purpose of this study is to investigate the direct effect of organizational health, as perceived by childcare teachers, on their turnover intention, and to examine the mediating effect of work-life balance on the relationship between these two variables. Methods: The subjects of this study were 345 childcare teachers working at 45 childcare centers located in Gyeonggi-do. Descriptive statistics, factor analysis, reliability analysis, and Pearson correlation analysis were performed using SPSS 21.0. Additionally, the mediating effect was verified using the PROCESS Macro, and bootstrapping was performed to confirm the significance of the indirect effect. Results: First, there was a significant negative correlation between the organizational health of childcare centers, the turnover intention of childcare teachers, and their work-life balance. Second, it was found that work-family balance completely mediated the relationship between the organizational health of childcare centers and the turnover intention of childcare teachers, while work-leisure balance and work-growth balance partially mediated the relationship between these two variables. Conclusion/Implications: This study provides essential data for examining ways to lower the turnover intention of childcare teachers by addressing both individual and organizational dimensions.

  • 신재생 에너지 개발에 대한 사회적 요구가 증가하면서 경제성 및 기술 성숙도가 높은 풍력발전이 많은 관심을 받고 있다. 대규모 에너지 생산을 위해 풍력 터빈의 대형화와 해상풍력 단지 개발에 대한 많은 연구가 진행되고 있으며, 운영 및 관리(O&M, Operation and Management) 측면에서의 구조적 안전성 평가 및 유지관리의 중요성 또한 지속적으로 증가하고 있다. 안전성 평가를 위한 여러 항목 중 터빈 상부 즉, 허브 높이에서의 변위는 구조물의 강성에 의해 지배되는 직접적인 지표로, 구조물의 건전상태를 쉽게 평가할 수 있는 지표라 할 수 있다. 그러나 풍력 터빈과 같은 대형 구조물의 변위 측정은 장비의 한계로 직접적으로 측정하기에는 많은 어려움이 따른다. 따라서 이 연구에서는 (1) 경사와 가속도의 동적 계측응답 자료를 융합하여 간접적으로 변위를 추정하는 방법을 제안하고, (2) 제안된 방법을 제원이 공개되어 있는 NREL 5 MW급 풍력 터빈에 적용하여 경사계의 수, 경사계의 잡음 수준 및 계측 주파수에 따른 변위 추정의 정확도를 평가하였으며, 실제 변위 측정을 위한 매개변수 연구를 수행하였다.
