현미경을 이용한 자동화된 검사 공정에 있어서 무엇보다 중요한 과정은 초점조절이며, 피 측정물의 선명한 현미경 영상을 얻기 위한 빠르고 신뢰도가 높은 자동초점조절 방법들은 일련의 검사공정에 있어서 필수 불가결한 요소로 자리매김 하고 있다. 일반적으로 널리 사용되고 있는 수동형 자동초점조절 방법들은 측정물체 표면의 영상대비 정보를 이용하는 방법으로 구성이 비교적 간단하지만, 최대대비 위치를 찾기 위한 주사과정이 필요하므로 시간 소요가 크고, 시편에 대한 의존도가 높다는 단점이 있다.(중략)

This paper implement an Camcorder NTSC camera autofocus control system on the DSP Board. The information of camera lens control obtain the only brightness simple image processing from the NTSC camcoder camera image. The exact focus makes the exact boundaries. The camera lens control that the increase sum of the useful ingredient values. Useful value obtained experiment value. Also noise is except because a big value of the ingredients so that obtained focus more accurate value.

Based on the affective event theory, the purpose of the study is to examine the effect of the individual difference regulatory focus on the process in which the work events affect job engagement under organizational circumstances. To this end, 232 financial workers were surveyed on positive events, positive affects, regulatory focus and job engagement. The results of the analysis are as follows. First, the positive events generated positive affects and showed positive influence on job engagement. Second, the effect of positive affects on job engagement has been shown to be discriminatory depending on the level of regulatory focus. The higher the level of promotion focus, the stronger the effect on job engagement of positive affects, and the higher the level of prevention focus, the weaker the effect on job engagement of positive affects. Third, the moderated mediated effect was found to be significant only in the prevention focus. The magnitude of indirect effects on job engagement by positive events was found to be weakened when the prevention focus was high. Finally, the implications and future research issues were discussed.

The passive focusing method finds the in-focus position by analyzing images captured by a camera. In this paper, we propose an efficient passive auto-focusing algorithm for video measuring systems. The sum of modified Laplacian of Gaussian is used to calculate focus values from images and Gaussian curve fitting is applied to estimate the optimal in-focus position. The Proposed method is tested for various objects and illuminations. The test result is compared with other methods to verify accuracy and efficiency of the proposed algorithm.

We analyzed the relationship among customer value, satisfaction and continuous use intention of tourism social commerce in this study. And also we observed the moderating effects of regulatory focus on the relationship between customer value and satisfaction. As the results, we found partially positive relationship between customer value and satisfaction and positive relationship between satisfaction and continuous use intention of tourism social commerce. The regulatory focus partially moderated the relationship between customer value and satisfaction. Finally we emphasize the importance of customer value, enhancing promotion focus and weakening prevention focus for continuous use intention of tourism social commerce.

Head fixed type multi-focus display system using Galvano-scanner and DMD(Digital Micro-mirror Device), which is able to perfectly accommodate, can solve eye fatigue due to conflict between convergence eye movement and accommodation action in stereoscopic display. This system is able to accommodate through making convergence point about each view point and offering it in front of observer's pupil by using laser scanning method. In this paper, we analyzed laser scanning method of this multi-focus display system. And multi-focus display system based on this analysis was made, which showed that focus adjustment was possible through video camera. As a result, formation principle of view point of multi-focus system by laser scanning method was verified.

In this study, we investigated path that influence task performance through mediation of leader identification, regulatory focus (promotion focus and prevention focus). The results of this study are summarized as follows. First, ethical leadership has a positive effect on leader identification. Second, leader identification has played a crucial role in the relationship between ethical leadership and regulatory focus, and regulatory focus also have an important mediating effect on the relationship between leader identification and task performance. These results show that leader identification, regulatory focus play as an important mediator in relationship between ethical leadership and task performance.

In this paper, we propose methods to improve image-based auto-focus that can compensate for drawbacks of traditional auto-focus control. When adjusting the focus, there is a problem that the focus window cannot be set to the same position if the camera's LOS is not directed at the same location and flow or shake. To address this issue, we applied image tracking techniques to improve optimal focus localization accuracy. And also, although the same focus value should be calculated at the same focus step, but different values can be calculated by camera's fine shaking or image disturbance due to atmospheric scattering. To tackle this problem a SAFS (Stable Adjacency Frame Selection) has been proposed. As a result of this study, our proposed methodology shows more accurate than traditional methods in terms of finding best focus position.

The purpose of this paper is to examine the effect of entrepreneurial self-efficacy on entrepreneurial intention. Further, the paper aims to study the moderating effect of regulatory focus in the relationship between entrepreneurial self-efficacy and entrepreneurial intention. As per regulatory focus theory, individuals have different goal attainment approaches and underlying motivations; this posits two distinct orientations: promotion focus and prevention focus. Consequently, we hypothesize that the effect of entrepreneurial self-efficacy on entrepreneurial intention would differ depending on the individual's regulatory focus, either promotion or prevention. In order to test the hypotheses, we select a random sample of 494 entrepreneurship students at six universities across the country. The analysis includes a survey of 309 students. The results indicate that students' entrepreneurial self-efficacy has a positive effect on their intention to become entrepreneurs. Further, regulatory focus moderates the relationship between entrepreneurial self-efficacy and entrepreneurial intention. Specifically, the impact of entrepreneurial self-efficacy on entrepreneurial intention is greater in promotion-focused students than in prevention-focused students. The results highlight the need for education methodology that enhances students' entrepreneurial self-efficacy and specialized entrepreneurship education for prevention-focused students.

The purpose of this study was to investigate the differences of influence between luxury brand value and preferences according to consumers' regulatory focus. For data collection, research questionnaires were responded by females consumers living in Pusan and Ulsan. The collected data were analyzed according to the frequency-factor analysis using SPSS 14.0 for windows Package, the factor analysis using Varimax, reliability analysis, T-test, multi-regression analysis, and chow-test. The results were as follows: First, Based on an independent samples t-test, It was found that prevention-oriented respondents were significantly more qualify value and economic value than promotion-oriented respondents, promotion-oriented respondents were significantly more aesthetic value than prevention-oriented respondents. Second, concerning the worth of luxury brands that aesthetic value, qualify value, economic value, conspicuous value, and emotional value significantly affected the consumers' preference about luxury brand. On the other hand, only social value of the luxury brand did not have a significant effect on the consumers' preference about luxury brand. Second, the study was to investigate whether the luxury brand value has an effect on the brand preference depending on the consumer's regulatory focus. The results showed that there were different perceived values of luxury brand preference between the promotion-focused and the prevention-focused consumers. The promotion focus group had the effect on conspicuous value and emotional value, while the prevention focus group had the effect on quality value and economic value for luxury brand preference.
