This study examined discrepancies in the brand image of a Japanese frozen food company perceived by the company’s employees and its consumers. Using a hypothesized model leading to brand loyalty, structural differences between the company’s employees’ (internal) and consumers’ (external) brand images were revealed: the two images did not structurally match.

This study selected fashion brands claiming to advocate feminism to analyze their characteristics and female images. For the study’s data, online foreign feminist fashion brands were sifted from March 2017 to January 2018 and 28 clothing brands were selected. The study’s results show that feminist fashion brands aim at the demassification and individualization of fashion products to be more inclusive of individuals’ physical characteristics and diversity. Additionally, feminist brands entice consumption through communication and participation in online communities and through the value of social coexistence. The essential female image produced by feminist fashion brands deconstructs a socially idealized female image and expresses a sense of self-body positivity. In turn, the concept of self-body positivity is communicated through natural images of independent women with distinct identities based on differences in race, culture, and sexual orientation. Moreover, feminist fashion brands produce social images featuring independent women using active wear to engage in social activities. Casual wear is also used to reflect active women, while mannish looks and power suits express women’s social status and professional abilities. Ultimately, these offer functionally active and rational images, combined with female images featuring long hair and makeup. Yet another type of female image seeks to create a new vision of women as diverse due to their various cultures, countries of origin, races, and individual tastes. These new images express women’s physical differences, distinct identities, and diversity while simultaneously deconstructing pre-existing forms of clothing.

The near real-time speckle masking reconstruction technique has been developed to accelerate the processing of solar images to achieve high resolutions for ground-based solar telescopes. However, the reconstruction of solar subimages in such a speckle reconstruction is very time-consuming. We design and implement a new parallel speckle masking reconstruction algorithm based on the Compute Unified Device Architecture (CUDA) on General Purpose Graphics Processing Units (GPGPU). Tests are performed to validate the correctness of our program on NVIDIA GPGPU. Details of several parallel reconstruction steps are presented, and the parallel implementation between various modules shows a significant speed increase compared to the previous serial implementations. In addition, we present a comparison of runtimes across serial programs, the OpenMP-based method, and the new parallel method. The new parallel method shows a clear advantage for large scale data processing, and a speedup of around 9 to 10 is achieved in reconstructing one solar subimage of 256×256 pixels. The speedup performance of the new parallel method exceeds that of OpenMP-based method overall. We conclude that the new parallel method would be of value, and contribute to real-time reconstruction of an entire solar image.

Pavement Condition Index (PCI) is an important index to establish a proper maintenance and rehabilitation strategy of a road network. The index is calculated based on the present state of surface defects, deformation and cracking. The information is normally obtained by visual inspection and observation of road networks. Nowadays, various sensor-based visual inspection techniques are applied to obtain detailed information of a road network, and to automate the entire process of calculating PCI. Hyperspectral analysis is a technique to identify the spectral signature of a material in the electromagnetic spectrum. The technique is being applied to pavement condition evaluation. Some researchers have reported that Exposed Aggregate Index (EAI) has a relationship with the reflectance of a hyperspectral image of a road network. In this study, the possibility of using hyperspectral images for pavement condition evaluation is experimentally investigated and the relationship between EAI and PCI is addressed.

This research aims to explore whether guided visual artwork discussions called Visual Thinking Strategies (VTS) using picture book images can benefit and enhance Korean EFL secondary students’ L2 writing. Incorporating content analysis, this research examines how carefully guided artwork discussions can enhance visual understanding, critical thinking skills and interpretive L2 writing skills. The L2 writing samples of the focal students revealed that they were able to think based on visual clues. The discussions were led by the teacher who pointed out significant visual elements and allowed time for the students to explore diverse ideas. The focal students were able to piece together the jigsaw of the images and articulate their thoughts in English, during which time they learned to take risks and to make mistakes in using a foreign language. Their critical comments and improved L2 writing suggest how critical/aesthetic thinking skills can be developed through continued visual practices in a secondary EFL setting.

본 논문에서는 게임 배경 영상에 대해서 섬세한 일러스트레이션부터 거친 스케치까지 다양한 연필 드로잉 효과를 구현하는 방법을 제안한다. 이 방법은 컨볼루션 알고리즘에 기반한 방법으로 노이즈의 형태를 다양화 시켜서 발생시킴으로써 다양한 연필 효과를 추구한다. 기존의 방법에서 발생하는 노이즈는 영상의 톤을 반영 하는 픽셀 크기의 입자였다. 본 논문에서는 이러한 픽셀 크기의 노이즈의 형태와 분포를 확장해서 다양한 길 이와 두께 및 방향을 갖는 사각형 형태의 노이즈를 사용하는 방법을 고안한다. 그리고 영상 분할 알고리즘을 적용해서 영상의 정보를 추가적으로 활용함으로써 결과 영상의 시각적 완성도를 향상시킨다. 이러한 방법의 장점은 물체, 인물, 장면 등과 같은 다양한 게임 배경 영상에 적용되어 생성된 결과 영상의 우수성을 통해서 입증된다.

수심이 깊은 바다 속을 광학 카메라로 촬영하는 경우 영상 왜곡이 일어날 수 있다. 이런 문제는 해수와 각종 부유물로 인 해 태양광이 충분히 전달되지 않아 발생하게 된다. 특히, 수심에 따라 녹색과 청색 계열의 색상이 지나치게 강조되는 색상의 왜곡과 해수에 의한 빛의 굴절과 부유물로 인한 경계선 부분에서의 왜곡현상이 발생한다. 이와 같은 왜곡들로 인하여 수중영상의 전반적인 화질이 저하된다. 본 논문에서는 정박 중인 선박의 하부를 촬영한 수중영상을 대상으로 영상분석을 수행한다. 그 결과를 기반으로 색 상을 보정하고, 윤곽선을 강조하는 기법을 제안한다. 실험결과 제안한 기법을 적용할 경우 원본 수중영상의 유효 윤곽선 보다 3.39 % 정도 윤곽선의 수가 증가하는 결과를 얻을 수 있었다. 또한, 정량적인 평가와 함께 주관적인 화질평가를 병행한 결과 색상 보정과 함 께 객체의 경계부분이 명확해지는 것을 확인할 수 있었다. 본 논문에서 제안한 수중영상의 색상 보정과 윤곽선 강조 기법은 향후 수 중영상 촬영이 필요한 여러 분야에 응용될 수 있을 것으로 사료된다.

The well-known solar cycle controls almost the entire appearance of the solar photosphere. We therefore presume that the continuous emission of visible light from the solar surface follows the solar cyclic variation. In this study, we examine the solar cyclic variation of photospheric brightness in the visible range using solar images taken by the Solar and Heliospheric Observatory (SOHO)/Michelson Doppler Imager (MDI). The photospheric brightness in the visible range is quantified via the relative intensity acquired from in the raw solar images. In contrast to total solar irradiance, the relative intensity is out of phase with the solar cycle. During the solar minimum of solar cycles 23--24, the relative intensity shows enhanced heliolatitudinal asymmetry due to a positive asymmetry of the sunspot number. This result can be explained by the strength of the solar magnetic field that controls the strength of convection, implying that the emission in the visible range is controlled by the strength of convection. This agrees with the photospheric brightness increasing during a period of long spotless days.

In this study, we conducted an empirical analysis using structural equation modeling (SEM) by distributing questionnaires to 208 Chinese tourists who constitute the largest proportion of foreign tourists visiting South Korea. The survey was conducted in a face to face (FTF) manner with the aim to contribute to globalization of Korean cuisine through comprehensive analysis of the effects of preference characteristics of Korean wave dramas on the relationship among images, attitudes, and purchase intentions for Korean cuisine. The main actor characteristics among the preference characteristics of Korean wave dramas had a significant effect on the attitudes and purchase intentions for Korean cuisine. However, the thematic characteristics among the preference characteristics of Korean wave dramas did not have a significant effect on the purchase intentions for Korean cuisine; in addition, the production characteristics did not have a significant effect on the attitudes and purchase intentions for Korean cuisine. The eco-friendly and health images of Korean cuisine had a significant effect on the purchase intentions for Korean cuisine, and the attitudes toward Korean cuisine significantly affected the purchase intentions for Korean cuisine. Based on the results of this study, it is considered necessary to continuously publicize Korean cuisine through Korean wave dramas to build positive attitudes toward Korean cuisine through enhanced images of Korean cuisine.

This study analyzes the images of models in womenswear advertisements targeting women in their fifties. The goals of this study are: 1) to investigate beauty ideals for middle-aged women by analyzing models’ look age, chronological age, wrinkles, gray hair, hair length, body type, and race; and 2) to explore how ageing is dealt with in advertisements by analyzing the range of bodies shown in advertisements, the color mode of photographs, and the clarity of models’ figures in relation to models’ look ages. A total of 155 printed advertisements from January 2012 to January 2017 from the brands Daks Ladies, Lebeige, Luciano Choi, PAT, and Zishen were selected for analysis. Womenswear brands targeting middle-aged women reinforce cultural ideals of female beauty that emphasize youth and slenderness. They do this by using thin and slender models, who most often appear to be in their twenties and thirties, and have hair longer than their shoulders. Brands with higher price ranges show a preference for Caucasian models, which reveals that a Caucasian identity is associated with sophistication. In addition, the bodies of models who appear to be in their forties and fifties were concealed by framing photographs mostly above the knees. Older models’ features were also obscured via the use of black and white photography, strong lighting and contrast, and digital editing that blurred the boundaries between figures and their backgrounds. These decisions for how to represent models could result in negative self-esteem and a denial of the symptoms of ageing among middle-aged women.

오늘날 예술에 있어서 공포의 표현은 인간성의 상실, 환경의 파괴, 인간관계에서의 소통의 부 재 등을 소재로 여러 분야에서 나타나고 있다. 예술작품에 표현된 공포 이미지에 대한 인간의 감정은 사회적, 외부 환경적, 심리, 유전적 원인 등으로 다양하게 나타날 수 있다. 특히 여러 예술 장르 중 영화는 이러한 공포 유발의 원인들을 표현하기 위해 이야기(내용)와 영상이미지(형식)를 함께 사용하게 된다. 이러한 표현 방식은 관객의 공포를 극대화시키는 효과를 갖게 된다. 따라서 공포영화에 있어 공포를 유발하는 이미지는 매우 중요한 관객 수용의 요인이 될 수 있다. 하지만 그럼에도 불구하고 공포영화의 이미지와 표현방법에 대한 관객 인식유형의 연구는 현재까지 많 이 이루어지지 않고 있다. 이에 본 연구는 질적 방법론 중 하나인 Q방법론을 사용하여 공포 영화 속 혐오성 이미지에 대한 수용자의 주관적 감정의 상태와 유형을 분석해 보았다. 그 결과 다음과 같은 3가지 인식 유형을 도출할 수 있었다. 먼저 신체적 가해에 대한 공포 감정을 느끼는 유형이 다. 이 유형은 잔인함 혹은 신체적 가해로 인해 나타나는 불안함을 공포의 감정으로 표출하고 있다. 다음으로 낯섦에 대한 공포는 알려지지 않는 악령이나 초자연적 현상 혹은 여성에 대해 두려움을 느끼고 있는 유형이다. 마지막으로 기형적 혐오성에 대해 공포를 느끼고 있는 유형은 이질적인 것들 인간과 다른 괴물이나 외계 생명체에 대해 공포의 감정을 갖고 있는 유형이다. 이러한 분석으로 도출되는 가설을 바탕으로 추후 계량적 방법론을 통한 연구가 추가적으로 수행 된다면 더욱 더 유의미한 연구결과를 도출해 낼 수 있을 것이다.

Cryptography is a science to maintain the security of the message by changing data or information into a different form, so the message cannot be recognized. Today, many algorithms have been proposed for image encryption, but the chaotic encryption methods have a good combination of speed and high security. In recent years, the chaos based cryptographic algorithms have suggested some new and efficient ways to develop secure image encryption techniques. The chaos-based encryption schemes are composed of two steps: chaotic confusion and pixel diffusion. In the chaotic confusion stage, a combination of the chaotic maps is used to realize the confusion of all pixels. In this paper, we first give a brief introduction into chaotic image encryption and then we investigate some important properties and behaviour of the logistic map. The logistic map, aperiodic trajectory, or random-like fluctuation, could not be obtained with some choice of initial condition. Therefore, a noisy logistic map with an additive system noise is introduced. The proposed scheme is based on the extended map of the Clifford strange attractor, where each dimension has a specific role in the encryption process. Two dimensions are used for pixel permutation and the third dimension is used for pixel diffusion. In order to optimize the Clifford encryption system we increase the space key by using the noisy logistic map and a novel encryption scheme based on the Clifford attractor and the noisy logistic map for secure transfer images is proposed. This algorithm consists of two parts: the noisy logistic map shuffle of the pixel position and the pixel value. We use times for shuffling the pixel position and value then we generate the new pixel position and value by the Clifford system. To illustrate the efficiency of the proposed scheme, various types of security analysis are tested. It can be concluded that the proposed image encryption system is a suitable choice for practical applications.

This study aims to acquire basic data for creating a new landscape forest by examining and analyzing both current and desired images of a forest in a rural neighborhood park. Regarding the forest in Janggye Neighborhood Park, located in Janggye-myeon, Jangsu-gun, Jeollabuk-do Province, this study conducted a questionnaire, using one-on-one interviews, to survey residents in Janggye-myeon who visited the park, and a total of 58 questionnaire copies were used for analysis. The current image about the forest was analyzed as giving a common and non-mysterious impression, and the subjects did not notice seasonal changes very much. Overall, the residents had negative images about the current forest. The desired image of the forest is a forest that is amiable, beautiful, comfortable, safe, and pleasant. A t-test was conducted to identify differences between the current image and the desire image, and its results showed that there were significant differences in most variables. The factor group implying the forest image consists of fascination dimension and diversity dimension. When factor scores of the current image and the desired image were compared, there were bigger differences in the fascination dimension scores than in the diversity dimension scores. As a result, it is drew that it would be much more effective to prioritize images related to fascination dimension in creating a forest landscape in Janggye Neighborhood Park.

The study investigates the effect of different types of visual images, i.e., static images versus dynamic images, on English vocabulary learning. Eighty-four students in the fourth grade of an elementary school participated in this study, and they were divided into two experimental groups and a control group. One of the experimental groups utilized static images, and the other group, videos as dynamic images in vocabulary learning. The control group was provided with the definition or the explanation of each target word in L1. The results of the study manifested that the static image group showed higher scores for the post test than the dynamic image group. The comparison of the pre and post affective tests demonstrated that the static image group showed an improvement in confidence in language learning and the dynamic image group showed positive change in the attitude of all three areas: interest, confidence, and aroused motivation. The analysis of the open-ended questionnaires showed that many participants in the static image group tended to use pictures as retrieval cues to remember vocabulary.

OBJECTIVES : Visibility at night can be improved by using retroreflection for short distances and phosphorescent line markings for long distances. In this study, we analyzed the characteristics of the phosphorescent line marking through a laboratory luminance test. Field performance analysis was performed through tests conducted on the road. We also examined the luminance measurement methods using the digital image obtained during the phosphorescent visibility evaluation. METHODS : In this study, the laboratory luminance test of the phosphorescent line marking was conducted using seven specimens to characterize the luminance changes according to the type of the glass beads, the thickness of the phosphorescent line marking, and the brightness and irradiation time of the light source. Phosphorescent and general line markings were made at 150 m to investigate the field luminance performance. A preliminary review of the luminance measurement methods was made using a digital image from a digital singlelens reflex (DSLR) camera. The measured luminance ratio of the general and the phosphorescent line markings was compared with the calculated luminance ratio using luminance analysis. RESULTS: Through the laboratory luminance test, it was seen that the change in luminance, which corresponds to the brightness of the light source, appears large but the influence of the thickness and irradiation time is low. The field performance test of the phosphorescent line marking conducted on the road involved measuring the luminance on the day the marking was made and 7 days after the marking was made. The luminance was found to be 190 mcd/m2 at 30 min after sunset and approximately 10-12 mcd/m2 4h after sunset. The results of the luminance test were captured using a digital image for each time group. The luminance ratio of the phosphorescent line marking, when compared to that of the general line marking, showed a similar trend within a 13% maximum error. Additionally, when this luminance ratio is compared to the direct field measurement, it could be confirmed that the luminance ratio, as captured in the digital image, showed a similar tendency. CONCLUSIONS : 1) The change in luminance corresponding to the brightness of the light source is significant in comparison with that corresponding to the thickness and the irradiation time. In addition, the results of the field test for the phosphorescent line marking satisfied the phosphorescent fire protection standard. 2) We examined the validity of the luminance measurement method using a digital image and we concluded that the change in the luminance ratio shows a similar tendency in both the cases. The results can form the basis for luminance measurement methodology for the construction and maintenance of phosphorescent line markings.
