  • Purpose: As the digital environment has expanded opportunity for consumers to acquire information from social media and social network services(SNS), With this environment, influencer has not only promoted products, but also participated in distribution and influencing on their followers. Despite the increasing interest in influencers, there has not been enough research on the structure of fashion influencer, relationship of immersion and purchase intention. This study examined the effects of fashion influencers' characteristics to the immersion of relationship with followers and purchase intention. Research design, data and methodology: For data collection, a pilot survey and the final survey were conducted. The pilot survey data was conducted to 50 female SNS users following fashion influencers. Based on the pilot tests, questionnaire was revised and the final survey was conducted online from august 22 to September 1, 2019 to female SNS users who have followed fashion influencer. A total of 408 data were collected, and exploratory factor analysis, correlation analysis, and structural equational modeling techniques were employed for the data analyses using AMOS 26.0 and SPSS 26.0. Results: First, five factors were extracted for the fashion influencers' characteristics: interactivity, similarity, reliability, expertise and attractiveness. Second, fashion influences' reliability, expertise, similarity, interactivity have a positive (+) effects on relationship immersion; however, attractiveness has no effect on relationship immersion with followers and fashion influencer. It was also determined that relationship immersion had positive (+) influences on purchase intention. The relationship immersion has been found to have a partially mediated effect and similarity has complete mediated effects between interactivity, reliability, and expertise of fashion influencers and purchasing intentions. In terms of fashion opinion leadership, it was found to have a significant influence on purchase intention only for low fashion leadership groups. Conclusions: The present study found the structural relationships among the influencer characteristics, relationship immersion and purchase intentions to provide framework for succeeding research. This research revealed academic association of intention of purchasing through use of fashion social media and fashion influencer marketing. The results also showed the practical implications that fashion influencers' expertise and reliability perceived by their followers are key determinants to success in influencer marketing.

  • 기존의 전문성 연구들은 참가자들에게 일상적인 과제를 수행하게 함으로써 전문가와 초보자들의 차이를 알아보고자 하였다. 하지만, 본 연구는 일상적 비행 상황에 익숙해진 조종사들이 이전에 경험해보지 못한 새로운 비행 상황에서도 유연하게 대처할 수 있는지 알아보고자 하였다. 즉, 조종사의 숙련정도에 따라 정상적 및 비정상적 상황에서의 상황인식 능력이 차이가 나는지 관찰하였고 추가적으로, 전문성이 자극 제시 시간에 따른 수행변화에 영향을 주는지 알아보았다. 이를 위해 42명의 조종사들을 전문성의 정도에 따라 초보자와 전문가 집단으로 나누고 이들의 수행이 상황의 특수성 및 자극 제시 시간에 따라 어떻게 달라지는지 알아보았다. 연구를 위하여 조종실 계기판을 모방한 동영상이 제작되었는데, 동영상에 보여지는 계기판들이 모두 정상으로 움직이는 정상적 상황과 이들 중 하나의 계기가 오작동을 일으키는 비정상 상황이 연출되었다. 또한 상황을 지각하기 위한 시간의 차이가 전문성에 따라 다른 효과를 가져오는지 살펴보기 위해서 계기판 상황이 오랫동안 제시되는 긴 제시 조건과 상대적으로 짧게 제시되는 조건으로 조작되었다. 실험 결과, 정상적인 상황에서는 초보자와 전문가 집단 사이의 상황 인식이 유의한 차이가 없었으나, 비정상적인 상황에서는 전문가 집단의 상황인식이 초보자 집단보다 유의하게 높은 것으로 나타났다. 또한, 비행 상황의 제시 시간이 짧아졌을 때 조종사들의 전반적인 상황인식 정확도가 떨어졌지만, 전문가와 초보자의 수행차이는 변함없이 초보자 집단에 비해 전문가 집단의 높은 수행이 유지되었다. 비행 상황의 특수성과 제시 시간의 상호작용에 따라 초보자와 전문가의 상황인식은 어떻게 달라지는지 보았을 때, 비행 상황의 제시 시간이 길고 짧음에 관계없이 정상적 상황에서는 초보자와 전문가 집단의 상황인식 차이가 나타나지 않았으나, 비정상적 상황에서는 전문가 집단의 상황인식 정확도가 초보자 집단 보다 유의하게 높은 것으로 나타났다. 전반적으로 볼 때, 비정상적 상황은 전문가 집단의 수행에 미치는 영향에는 큰 영향을 미치니 못하나 초보자 집단의 수행에는 현저한 영향을 미치는 것으로 나타났다.

  • This study aimed to provide empirical evidence about expert performance approach in aviation field and the results suggested that the amount of experience(e.g. total flight hour) is necessary but not sufficient index of a pilot's expertise or superior performance. 43 pilots participated and completed a spatial span task and SA (situation awareness) tasks. To explore the factors predicting the performance in routine and non-routine situations, discriminant analysis was conducted. The results of discriminant analysis indicated that different variables are related with the performance in routine and non-routine situation. The factors predicting performance in routine situation were the spatial span scores and total flight hours. On the other hand, the factors predicting performance in non-routine situation were age and the qualification for instrument flying. In real world, total flight time which represents the quantity of experience has been frequently used to predict flight abilities and as an important index of expertise. The results of this study suggest that these kinds of factors have to be used cautiously to predict the performance in abnormal situation.

  • Currently, flight training is not only a technical instruction that teaches maneuvering operations, but has expertise equal to that of general disciplines. Therefore, flight instructors must have academic knowledge and flight skills. As flight instructors are the first teacher in flight training for students who have never experienced actual flight control, the behavior of flight instructors will affect the students' flight education. Therefore, the influence of flight instructors for students are quite large compared to other educational institutions. In this study, the factors of instructional behavior were determined, and the actual state of instructional behavior of flight instructors were confirmed through students' survey. Improvements were derived to solve the problems identified in the survey results. For the follow-up analysis, improvements were applied to the flight instructors for 8 months, and then re-question was conducted to the same students who responded to the first questionnaire to find out the difference in results before and after through a paired t-test.

  • It has already been four years as of 2013 since the Departmentalized Classroom System was first introduced following the Korean government's policy. However, no investigation had been made yet on whether the system is properly being managed in practice according to the presented standards, guidelines, and policy direction. Hence, an in-depth investigation and analysis were called for. In line with this, documents were researched, deliberation meetings of experts were held, and the system pilot was tested to develop indices to investigate the state of block-scheduled classes and classes for each student's academic level for the educational classes field. For the school management field, we developed indices to investigate the teachers' organization and their division of labor, administrative officers and work reduction, improvement of teachers' expertise, and the guidance of the students' school life. Based on the indices, we investigated the state of 24 schools, which manage an advanced school system, nationwide. The results showed that the Departmentalized Classroom System has now reached the settling stage, which is beyond the introductory stage, and that it needs to be systematically supplemented for it to be settled in a stable manner.

  • This research aims to develop a model to objectively and quantitatively measure the skill level of aircraft body assembly workers. Because aircraft body assembly is predominantly a manual process, skills management is a key factor of manufacturing competitiveness. Currently, skills management relies on the subjective judgment of supervisors, which lacks objectivity and reliability. As a remedy, this study proposed a systematic skill management model based on objective and quantitative evaluation criteria. By considering prior research, we developed an evaluation model that takes into account both expertise and versatility of a worker. The model selected five major tasks required for aircraft body assembly and established evaluation criteria considering the difficulty and maturity of each task. We then conducted a pilot evaluation with over 200 workers in four SMEs to validate the practicality and effectiveness of the model. Consequently, we identified and addressed the limitations of the existing evaluation method, subdivided the skill levels based on the performance capabilities of each task, and proposed a career growth path. The developed evaluation model offers critical data for executives and managers to determine work assignments, education, training, performance incentives, and wages. It is expected to enhance the attraction of new talent and systematize skills management in aviation manufacturing in the future.
