In the image object classification problem, low-resolution images may have a negative impact on the classification result, especially when the classification method, such as a convolutional neural network (CNN) model, is trained on a high-resolution (HR) image dataset. In this paper, we analyze the behavior of applying a classical super-resolution (SR) method such as bicubic interpolation, and a deep CNN model such as SRCNN to enhance low-resolution (LR) weeds images used for classification. Using an HR dataset, we first train a CNN model for weeds image classification with a default input size of 128 × 128. Then, given an LR weeds image, we rescale to default input size by applying the bicubic interpolation or the SRCNN model. We analyze these two approaches on the Chonnam National University (CNU) weeds dataset and find that SRCNN is suitable for the image size is smaller than 80 × 80, while bicubic interpolation is convenient for a larger image.

브랜드 이미지는 고객, 이해관계자, 시장 전체가 해당 브랜드를 어떻게 보고 인지하는지를 뜻한다. 긍정적 브랜드 이미지는 계속적인 구매를 유발하지만, 부정적인 브랜드 이미지는 구매를 중단하게 만드는 등 소비자의 구매행동에 직결되기 때문에, 기업 입장에서는 빠르고 정확히 파악할 필요가 있다. 현재 브랜드 이미지를 조사하는 방법으로는 설문조사, SNS조사 등이 있는데, 표본의 수가 한정되고 시간과 비용이 많이 소요된다는 이슈가 있다. 따라서 본 연구에서는 딥러닝 기반의 KoBERT 모델을 활용하여 소셜미디어 상의 텍스트 데이터에 대한 감성분석을 실시한 후, 이를 브랜드 이미지 분석에 활용하는 방법을 제시하고, 이에 대한 성능을 검증하였다. 결과적으로, 다섯 개의 브랜드 이미지 순위를 매긴 결과가 한국기업평판연구소의 순위와 일치함으로써 본 연구의 사용성을 입증하였다.

Social networking services (SNSs) have become important and popular tools for not only presenting self-image but also sharing travel information. This study adopted self-image expressions to understand tourists' intentions to share travel information and behavioral changes in SNSs. To enhance understanding tourists' intention and behavior, the current study suggests a research model based on motivations for self-image expression (i.e., creativity, altruism and social relationship). This current study empirically resulted in the importance of users' creativity, altruism and social relationship in SNS, which leads to the intention and behavioral changes to share travel information. In addition, altruism moderated the negative effect of creativity on self-image expression as well as the positive effect of the social relationship on self-image expression. Based on the result of this study, the current study bears some implications in a theoretical and practical context.

Purpose: This article aimed to identify nurses' experience of practice in nursing homes. Method: Using phenomenological approach for qualitative research, the participants were 8 nurses who were working at nursing homse in C city. The data was analyzed by using phenomenological methodology by Colaizzi. Results: Five theme clusters were derived from the data. They were: burden (independent decision making in clinical situations, tension of as a multifunctional member); lowered self-esteem (exhaustion, relative self-evaluation is low, comparing with others); conflict (negative image of elderly, communication break with elderly family, monitoring of nursing home staff); worth (slight improvement of elderly health state, trust and recognition, intimacy); and self-reflection (need for knowledge extension, effort towards enhancing virtue, perception of importance in their health management). Conclusion: The results showed that nursing home nurses experienced negative aspects of various nursing practice, suggesting the ways to solve their negative experience.

This paper addresses the central issue of whether it is effective for a firm to discourage the purchase of its own product in order to support a social cause. The objectives of this study were: a) to examine whether a cause-related self-prevention ad would stimulate more positive evaluations compared to promotional ad, particularly when the product category is more negatively socially accepted; and 2) to determine if a negative attitude toward the product could induce a boomerang effect of a selfprevention ad. Results from three experiments revealed that socially responsible prevention campaigns against firm's own product may be more effective for the product category negatively associated with social concerns or welfare. If products are more limited in the social context, communications of product prevention are beneficial to improve the public image of the brand. However, the self-hurting approach may be inappropriate for potential customers who currently possess a strong negative attitude toward the product.

그림자는 자연 경관에서 관찰되는 일반적인 현상이지만 물체 인식, 특징 검출 및 장면 분석등과 같은 영상 분석에 부정적인 영향을 미치는 요소이므로 디지털 영상에 포함된 그림자 처리는 디지털 영상 분석 과정에서 필수적으로 고려되어야 한다. 본 논문에서는 단일 자연 영상에 포함된 그림자를 검출하고 제거하기 위한 특징 요소 중의 하나인 1D 불변 영상의 획득을 위한 기존 방법들에 대해 기술하고, 선형 회귀 기반의 1D 불변 영상 획득 방법을 제안하였다. 제안하는 방법은 RGB 칼라 영상의 각 채널 간의 밴드 비의 로그를 계산한 후 선형 회귀를 통해 그레이스케일 영상 라인을 획득하고, 최종 1D 불변 영상은 밴드 비의 로그 영상들을 추정된 그레이스케일 영상 라인으로 투영시켜 획득하였다. 실험 결과, 제안하는 방법이 기존의 엔트로피 최소화 기반의 투영 각도를 계산하는 방법보다 계산 복잡도가 낮았으며, 1D 불변 영상을 이용한 그림자가 검출 및 제거가 효과적으로 수행됨을 보였다.

By analyzing a national survey of public understanding of science and technology, this paper attempts to examine public perceptions of scientists and engineers in Korea. A special attention is given to the gap in the view of scientists and engineers across generation, gender, and class fields (or major fields). This paper shows that generation has the strongest effect on public perceptions of scientists and engineers among all the socio-demographic factors examined in this study. Those over 50 are more likely to have the conventional idealized images of scientists and the stereotypical negative images of scientists simultaneously, while the 20s are less likely to accept the idealized image of scientists. The survey result thus may suggest that the younger generation began to depart from a patriotic and moral description of scientists and engineers-for the younger generation, science and engineering is losing moral respect but becomes perceived as an ordinary occupation. Contrary to the popular belief, however, gender has little effect on public perceptions of scientists and engineers. This finding questions the assertion that female students possess more negative attitudes toward scientists and engineers than male students, and thus are reluctant to develop careers related to science and engineering. By uncovering that class fields (or major areas) have no effect on the image of scientists, this study also call into question the assertion in the science wars that the inadequate appreciation of science particularly among those who do not major in science and engineering is responsible for inadequate support for science and technology.

Recently, the demand for high definition TV is being increased by beginning of the digital broadcasting. The higher resolution of PDP is, the longer addressing time become, then, the sustain period for display image decreases. Because of the reason, dual-scan method which synchronously write information of an image on top and bottom of the screen is used for the high definition PDP. However, as the price competition of PDP becomes severe, we can`t avoid turning to a single-scan method which uses only a half of an expensive address IC. Accordingly, the sustain period becomes much shorter than prior method. In case of XGA level, it is impossible to display, eventually. In this paper, we are going to prove usefulness by realizing negative reset waveform and the driving circuit for high speed addressing.
