Film is a visual art. A process of film totally depends on our sense of sight. It indicates that a way of delivering narrative in the film is "showing", not "telling". There has already been established theories about "who sees" and "who tells" in narratology. It explains who the narrator is and how the narrator delivers in literary works which is represented in terms of "Point-of View". Therefore the study contents construct internal formal elements of the narrator and point of view into 2 individual researches, and the result can be summed up as below. From a narratological perspective, the narrator has roles and deeds as a narrative mediator who mediates the story and leads the story as presenting the origin with images and voices in the text extra and intra world through the process of producing the narrative inferred. To eliminate ambiguousness the term 'point-of view', this article applies 'focalization' theory to analyze narrative structure of film. The result of analysis shows that there are three focalizers in film; director, protagonist-character and camera. And aspects of film can be varied by distance of each focalizer. These distances between focalizers limit amount of visual information.

본 연구는 Schlater와 Sontag가 인간생태학적 관점에 기초하여 제시한 가치측정 모델에 의하여 국내 가정관리학 분야에서 이루어진 인간의 가치에 관한 연구를 분류하였다. 2차원의 매트릭스로 구성된 이 모델은 가치연구를 가치조사의 초점에따라 내용과 구조, 과정으로 분류할 수 있으며, 또한 피험자-가치대상 포함관계에 따라 3가지 측정접근법 즉, 피험자 단독, 피험자-가치대상 반응적, 피험자-가치대상 상호작용적 접근법으로 분류하고 있다. 이 모델을 분석도구로 사용하여 한국 가정관리학회지 창가호부터 1995년 13권 1호까지와 대한가정학회지 1983년 21권 1호부터 1995년 33권 1호까지에 수록된 논문중 인간의 가치를 연구한 논문과 몇편의 학위논문을 분석하였다. 그 결과 대부분의 연구들은 측정접근법상 피험자 단독 접근법이나 피험자-가치대상 반응적 접근법을 사용하면서, 내용에 초점을 두고 연구된 것을 알 수 있다. 미래의 가치연구방법으로 인간생태학적 접근법인 피험자-가치대상 상호작용 접근법과 과정에 초점을 맞추는 것이 요구되며, 우리나라 가치측정패턴에서만 특히 부족한 구조에 초점을 두는 것 또한 요구되어진다.

In this paper, the relation between the radiated sound and the vibration due to piezoelectric ESWL(Extracorporeal Shock Wave Lithotripter) is examined and the results of the experiments are represented. Next, the relation between the focal point and the vibration of the objects is examined. The same experiments with the objects that can be broken are done and the relation between the vibration and the break efficiency of the phantom is experimentally investigated. These results show that the relativity between the power of the peak frequency and the break efficiency can be confirmed.

인간은 초점정보를 이용하여 단안만으로도 공간의 깊이를 지각할 수 있다. 이것은 한 번에 하나의 대상물에만 초점을 맞출 수 있고 그 외의 부분은 흐림 현상을 유도함으로써 이루어진다. 이는 초점이 맞는 대상물체로부터 멀어지면 멀어질수록 흐림 현상이 강해지는 원리를 이용한 것으로 주파수 성분의 변화량에 대한 연산과 깊은 관련이 있다. 본 논문에서는 이와 같은 인간의 시각 시스템의 요소 중 하나인 초점정보를 모방하여 초점거리가 다른 각각의 이미지들에 각각의 가중치를 부여하였다. 그리고 각 이미지들을 일정 블록으로 각각 분할하여 초점이 가장 잘 맞는 블록을 찾아내어 하나의 이미지로 통합하였다. 이때 각 영역은 자신이 속했던 이미지의 가중치를 따르게 한다. 각 이미지에서 가장 포커스 수치가 높은 영역을 찾기 위한 방법으로 주파수 영역 기반 처리와 공간 영역 기반 처리를 결합 하였다. 주파수 기반으로는 FFT(Fast Fourier Transform)에서 고주파 부분의 영역을 뽑아내어 포커스수치를 계산하였으며, 공간 영역 처리 기반으로는 이웃픽셀과의 차이가 임계값이하인 것을 제외한 영역을 뽑아내어 저주파 영역의 연산을 제거하는 방법과 단순히 Laplacian measure만을 사용하여 저주파까지도 포함한 방법의 두 가지를 적용하였다. 최종적으로 3개의 포커스 측정값을 결합시켜 포커스 수치를 계산한 후 각 블록의 가중치에 맞게 하나의 이미지로 통합하여 상대적 깊이지도를 생성하였다.

In this paper, we propose a discriminative color quantization algorithm depending on the degree of focus of the regions. When we take pictures, we usually focus the object that we want to emphasize. This means that focused area on the photograph contains important information. If the focused area is displayed with more colors, we can express the important information in more detail. This paper proposes a color quantization method that determines the focused area and assigns more colors for the area.

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.

This paper investigates the information related to the radiated sounds during treatment using the extracorporeal shock wave lothotriptor(ESWL). First, we observe the vibration of the objects from the radiated sounds and extract the information about the change of the peak frequency from the relation between the vibration and the radiated sounds. Next, we observe the change of the peak frequency according to the position of the focus and demonstrate that it is more difficult to vibrate objects exactly at the focal point than above or below the focus of the ESWL device. Lastly, we analyze the relation between the cavitation and the radiated sounds and examine the benefiting condition for the object fragmentation.

In this paper, We compared middle-aged wearer's satisfaction of progressive multifocal lens and free-form progressive multifocal lens wearers, and investigate the direction of improvement of progressive multifocal lens. We tried to predict the development direction of progressive lenses in the future. The results of the survey, satisfaction of free-form progressive multifocal lens wearers was high, compared to normal progressive lenses. The price of free-form progressive multifocal lens is expensive compared to the nomal progressive multifocal lens, but provides a wide view than nomal progressive lenses. It was confirmed that there is sufficient merit. because it can be made in individual customized to the wearer. In the near future, It is expected that free-form progressive multifocal lenses is the most popular progressive multifocal lenses to middle-aged wearers.

The present study aims to investigate how Korean EFL learners' views of form-focused instruction, integrated and isolated FFI (form-focused instruction), are related to their beliefs about grammar and attention and how different these relationships are between high and low proficiency levels and between males and females in Korean college contexts. The findings indicated the participants' strong preference for integrated FFI, which was significantly correlated with two factors, attention in English class and English proficiency. On the other hand, the isolated FFI was strongly correlated with their beliefs about grammar learning, that is, independent learning of grammar and importance of learning grammar rules. In conclusion, the integrated FFI was associated with students' proficiency and attention, while the isolated FFI was related to their views of grammar learning. In conclusion, it is suggested that we need to use integrated FFI in Korean EFL contexts considering students' levels of proficiency and attention.

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.
