The purpose of this study is to examine the influence of LOHAS images of Japanese restaurants on customers' menu selection and satisfaction to provide useful information on proposing detailed marketing directions by deriving the importance and satisfaction factors of LOHAS images and to suggest practical and effective measures for using LOHAS images to improve menus at Japanese restaurants. The results of the study are as follows. First, as a result of examining hypothesis 1, "LOHAS images will influence essential factors," it was found that healthy ingredient, family-oriented, eco-friendly, sustainability, and energy-saving factors were influential. With greater family-oriented, sustainability, healthy ingredient, and eco-friendly factors in LOHAS image, interests in essential factors increased. Second, family-oriented, energy-saving, social-oriented, and sustainability factors in LOHAS image had a significantly positive impact on the environmental factors of menu. Third, eco-friendly, sustainability, family-oriented, energy-saving, healthy preparation, and healthy ingredient factors in LOHAS image had a significantly positive impact on customer satisfaction. Fourth, essential factors in the selection attributes of Japanese restaurant menu had a significantly positive impact on customer satisfaction. Fifth, environmental factors in Japanese restaurants had a significantly positive impact on customer satisfaction. The significance and limitation of this study are: first, Japanese restaurants would be able to build a better image with customers by providing menu items that are family-oriented, sustainable, and energy-saving. Second, it would be necessary to study how LOHAS factors influence customers' general purchase decisions and psychological factors.

Shadows are important elements in producing a realistic image. Generation of exact shapes and positions of shadows is essential in rendering since it provides users with visual cues on the scene. It is also very important to be able to create soft shadows resulted from area light sources since they increase the visual realism drastically. In spite of their importance. the existing shadow generation algorithms still have some problems in producing realistic shadows in real-time. While image-based rendering techniques can often be effective1y applied to real-time shadow generation, such techniques usually demand so large memory space for storing preprocessed shadow maps. An effective compression method can help in reducing memory requirement, only at the additional decoding costs. In this paper, we propose a new image-barred shadow generation method based on image warping. With this method, it is possible to generate realistic shadows using only small sizes of pre-generated shadow maps, and is easy to extend to soft shadow generation. Our method will be efficiently used for generating realistic scenes in many real-time applications such as 3D games and virtual reality systems.

This study analyzed the ignorance and prejudice with regard to African culture, which can be seen at the textbook and class course centering the geography class from 1990's to the present, and reviewed critically the related education and learning effects for mutual understanding. This study results are as follows: First, in the geographic environment contents, the image regarding huge continent, the local image regarding the various physical environments and the geographical importance as the ancient civilization birthplace were not included in the description. Second, the description regarding the African culture and history was focused to the singular African image, so the fixed concept and distorted image has been rooted into the formation of cultural meta-knowledge. Third, the negative sides rather than positive development and the past backward facts rather than changed status have been emphasized in the description regarding African resources and industry as well, so only the region surrounded with the various problems including poverty and the image as underdeveloped country have been rooted into the description. Now, real Africa view, an image for a variety of attractive and vibrant Africa rather than the same culture and characteristics of African must be learned in text books.

The purpose of this thesis is to examine ontology of digital photo image based on a Simulacre concept of Gilles Deleuze & Jean Baudrillard. Traditionally, analog image follows the logic of reproduction with a similarity with original target. Therefore, visual reality of analog image is illuminated, interpreted, and described in a subjective viewpoint, but does not deviate from the interpreted reality. However, digital image does not exist physically but exists as information that is made of mathematical data, a digital algorithm. This digital image is that newness of every reproduction, that is, essence of subject 'once existing there' does not exist anymore, and does not instruct or reproduce an outside target. Therefore, digital image does not have the similarity and does not keep the index instruction ability anymore. It means that this digital image is converted into a virtual area, and this is not reproduction of already existing but display of not existing yet. This not-being of digital image changes understanding of reality, existence, and imagination. Now, dividing it into reality and imagination itself is meaningless, and this does not make digital image with technical improvement but is a new image that is basically completely different from existing image. Eventually, digital image of the day passes step to visualize an existent target, nonexistent things have been visualized, and reality operates virtually. It means that digital image does not reproduce our reality but reproduces other reality realistically. In other words, it is a virtual reproduction producing an image that is not related to a target, that is to say Simulacre. In the virtually simulated world, reality has an infinite possibility, and it is not a picture of the past and present and has a possibility as the infinite virtual that is not fixed, is infinitely mutable, and is not actualized yet.

고해상도 이미지 센서를 장착한 고가의 모바일 제품들이 확산되면서 중간값 필터에 기반을 둔 잡음 제거 필터의 필요성이 증가하고 있다. 이는 초박형 카메라에 내장된 이미지 센서의 물리적인 수광부 면적이 줄어듦에 따라 이미지 센서의 SNR이 떨어지기 때문이다. 게다가 영상의 해상도가 매우 높기 때문에 잡음제거 필터는 초고속으로 동작해야 한다. 따라서 잡음 제거 필터의 핵심 기능인 중간값 필터는 높은 동작주파수에서도 효과적으로 동작해야 한다. 초고속으로 동작하는 필터를 하드웨어로 구현하려면 입출력 간의 물리적 지연시간을 클럭의 주기 단위로 나누어서, 시분할하여 순차적으로 처리하는 파이프라인 구조를 가져야 한다. 파이프라인 단계는 많은 비용이 소모되는 레지스터로 구현되므로 파이프라인 단계를 줄이는 것이 바람직하다. 본 논문에서는 입력부터 출력까지의 물리적 지연시간이 데이터의 수에 비례하는 기존의 중간값 필터와 달리, 데이터 수의 로그값에 비례하는 중간값 필터의 구조를 제안한다. 제안한 중간값 필터는 서로 다른 값을 가지는 데이터 집합에서의 중간값은 자신보다 큰 원소의 수와, 작은 원소의 수가 같다는 사실을 이용하며, 버블 정렬 구조에 기반을 둔 중간값 필터에 비해서 같은 동작주파수에서의 게이트 수가 25.3% 줄어든다. 중간값 필터는 잡음제거나 위색제거 등에서도 널리 사용되고 있으므로, 제안한 구조의 중간값 필터는 초고속으로 동작하는 이미지 신호 처리기의 효과적인 구현에 적합하다.

대체 불가능한 토큰을 의미하는 NFT 는 블록 체인 기반 기술 중 하나로 소유권과 거래 이력이 블록 체인에 기록이 된다는 장점을 지녀 미술 작품 거래에도 활발히 활용되고 있다. 하지만 현재 NFT 작품 거래 시장은 주식거래와 같이 회전율과 거래량을 중점으로 투기성이 짙으며, 작품의 섬네일 이미지만으로 거래 의사를 판단하는 경우가 많다는 문제점이 대두되고 있다. 따라서 작품의 다양한 특성에 대한 고려가 함께 이루어질 필요가 있다. 본 논문은 작품의 다양한 변수를 수집하여 최적의 변수 조합을 찾아내고, 이미지 전이 학습과 생성 알고리즘을 활용해 다양한 변수가 가격에 미치는 영향을 알아보고자 했다. 연구 결과 이미지 만을 활용한 가격 예측은 정확도가 높지 않다는 사실을 확인하였고 작품이 가진 여러 특성을 변수로 한 정형 데이터의 가격 예측 정확도가 더 높은 것을 알 수 있었다. 또한 생성 알고리즘을 통해 새로운 특성 조합의 작품들을 만들었고 가격을 수치 예측해보았다. 이를 실제 작가의 작품의 가격과 가격의 변동 추이를 대조해 작가의 작품 판매 가격 평균치 이상인 작품의 특성을 확인할 수 있었다.

The study aims at verifying the effect of the image, trust and responsiveness to social welfare organizations on continuing the sponsorship of private donors, the mediating effect of the organizational identification and the moderating effect of their financial status. As a result of causal analysis of the variables by structural equation models, regardless of donors' financial status, social welfare organizations' image, trust and responsiveness has no direct effect on continuing the sponsorship. Among the donors in relatively good financial status, social welfare organizations' image, trust and responsiveness positively have direct effects on organizational identification, which has a direct effect on continuing the sponsorship. That is, the image, trust and responsiveness influence the continuity of the sponsorship through the full mediating effect of organizational identification. On the other hand, among relatively poor donors, only the organizations' image and trust positively influence the organizational identification, The direct and indirect effects on the continuity of the sponsorship are different according to the private donors' financial status, which means that the moderating effect of the donors' financial status is proved. The result of latent mean analysis regarding 5 main latent variables according to the private donors' financial status, shows the significant difference in the continuity of sponsorship only(Mean= .197, Cohen's D=.779). By emphasizing that Organizational identification is a critical factor in terms of enhancing the continuity of sponsorship, some practical implications are discussed based on the study's findings.
