Since ChatGPT was released in 2022, the generative artificial intelligence (AI) industry has seen massive growth and is expected to bring significant innovations to cognitive tasks. AI-based image generation, in particular, is leading major changes in the digital world. This study investigates the technical foundations of Midjourney, Stable Diffusion, and Firefly-three notable AI image generation tools-and compares their effectiveness by examining the images they produce. The results show that these AI tools can generate realistic images of tomatoes, strawberries, paprikas, and cucumbers, typical crops grown in greenhouse. Especially, Firefly stood out for its ability to produce very realistic images of greenhouse-grown crops. However, all tools struggled to fully capture the environmental context of greenhouses where these crops grow. The process of refining prompts and using reference images has proven effective in accurately generating images of strawberry fruits and their cultivation systems. In the case of generating cucumber images, the AI tools produced images very close to real ones, with no significant differences found in their evaluation scores. This study demonstrates how AI-based image generation technology can be applied in agriculture, suggesting a bright future for its use in this field.

디지털 카메라의 사용이 일반화되면서, 사용자가 사진을 찍고 보관하고 감상하는 행태가 과거의 일반 카메라와 다른 모습을 보이고 있다. 특히 디지털 카메라는 유지비가 거의 들지 않기 때문에 한번에 촬영하는 사진의 양이 많은 반면에 인쇄하여 보관하는 사진의 양은 매우 적은 경향을 보인다. 디지털 사진의 양이 방대하게 늘어나고, 인쇄하기 보다는 저장 장치에 보관하게 됨에 따라서 과거의 앨범에 인쇄된 사진을 보관하고 감상하던 방식과 감상하는 행태도 변화되었다. 디지털 카메라로 찍어서 하드디스크에 저장한 사진들은 각 폴더에 어떤 사진들이 들어 있는지를 기억하기 어렵기 때문에 앨범을 보는 것처럼 자주 감상하지 않게 되는 경향이 관찰되었고, 또 인쇄된 사진을 보고, 그 사진과 연관된 다른 사진들을 보고자 디지털로 저장되어 있는 하드디스크에 접속하는 경향이 관찰되었다. 본 연구에서는 촬영된 디지털 카메라의 사진을 분류하여 보관하고 감상하는 사용자의 행태를 분석하고, 이에 적합한 새로운 디지털 사진 관리 시스템을 제안하고자 한다. 특히, 자연스럽게 앨범을 넘겨보다가 인쇄된 디지털 사진과 관련된 컨텍스트를 갖는 다른 디지털 사진들을 저장 매체에서 바로 찾아서 디스플레이를 통해 감상할 수 있는 새로운 방식의 UI를 제안하였다. 이를 위해 인쇄된 사진에 사진의 컨텍스트 코드를 함께 인쇄하고, 추후에 출력된 사진의 컨텍스트 코드를 해독하여 원본 디지털 사진 및, 동일한 컨텍스트를 가지는 디지털 사진들을 자동으로 찾아서 디스플레이 하는 검색 및 감상 방식을 사용하였다. 이를 통해 디지털 사진을 감상하기 위해 거쳐야 했던 기존의 번거로운 과정을 단축하고 디지털 사진을 분류하여 보관하고 원하는 사진을 방대한 데이터 속에서 찾아야 하는 문제를 줄일 수 있었다.

To measure the soil deformation, two common techniques of the digital image analysis-Particle Image Velocimetry (PIV) and Digital Image Correlation (DIC)-have been used. To generally apply these techniques to the soils, the accuracy of these techniques should be evaluated under various conditions. In this study, the influence factors including the image resolution, the degree of displacement and deformation, the size of pixel subsets, and analysis techniques were analyzed. The deformation of an idealized particle assembly using the discrete element method was measured by the digital image analyses, and then the results were compared with the actual deformations. To conduct the optimal digital image analysis, various factors are systematically analyzed in terms of the degree of the displacement and the deformation.

Diagnosis on setteability based on human operator's experimental knowledge, which could be established by long term operation, is a limit factor to construction of automation control system in wastewater treatment plant. On-line SVI(Sludge Volume Index) analyzer was developed which can measure SV30 automatically by image capture and image analysis method. In this paper, information got by settling process was studied using On-line SVI analyzer for better operation & management of WWTPs. First, SV30 detection algorithm was developed using image capture and image analysis for settling test and it showed that automatic detection is feasible even if deflocculation and bulking was occurred. Second, turbidity assessment model was developed using image analysis.

This study was attempted to investigate the effect of the first clinical practice on the image of nurse and nursing professionalism of nursing students in the COVID-19 situation. The data were collected from 36 nursing college students using a structured questionnaire from June to July 2020 and analyzed by PASW 22.0. After the first clinical practice in the COVID-19 pandemic, the nurse image (t=-2.219, p=.034) and nursing professionalism(t=-3.444, p=.002) increased significantly compared to before practice. Social image (t=-3.113, p=.004), self-concept of the profession(t=-2.442, p=.021), social awareness(t=-3.829, p=.001) and professionalism of nursing(t=-2.299, p=.028) significantly increased after the first clinical practice. After the first clinical practice, nursing professionalism showed a significant positive correlation with image of nurse(r=.831, p<.001). The attitude of nurses to cope with COVID-19 positively influenced nursing students' nurse image and nursing professionalism. Therefore, it is expected that will be used as basic data for preparing educational strategies after COVID-19.

In recent years, the digital media environment has begun to diversify, with a greater focus being placed on user-centric design. With the development of digital technology, the digital media environment has formed a vast network of information, which supports interactive communication between people, creating a need for user-centric research. Mobile displays, as a representation of the digital media environment, have the advantage of mobility through the use of thin screen displays and low-performance image sensors, which allow for miniaturization and power saving. However, this results in reduced colour accuracy compared to large displays. This study investigates users' colour perception when using dark and light mode mobile displays. Colour perception was measured using a psycho-physical experiment, which controls each colour attribute based on the 12 colours of KS. The results were analysed to determine whether there is a difference in colour perception between dark mode and light mode, and if the difference was statistically significant. Future research directions based on the results are then discussed.

In this study, in order to overcome the limitations of the particle size analysis method using a scanner, a microscope, or a laser, and to reduce the cost, a high-quality sampling of micro minerals is performed using an ultra-high-pixel DSLR camera and a MACRO lens. Using this, digital photos taken of standard mineral particles are analyzed to distinguish the size and shape of mineral particles at the level of grain of sand (a few mm ~ 0.063 mm). In addition, various photographing techniques for the production of three-dimensional images of mineral particles were sought, and an attempt was made to produce learning materials and images for mineral classification.

This study presented the analysis results and implications by identifying the structural relationship between the image of food tourism products, the long-term orientation of attachment, and the behavioral intention. The convenience sampling method of the non-probability sampling method was used, and the survey was conducted non-face-to-face due to COVID-19. This study was conducted for customers who live in Jeollabuk-do and Jeollanam-do and have experienced local traditional food. As for the survey method, the main researcher's acquaintances and related experts were consulted and utilized to select the survey subjects, and the survey was conducted by sending/returning them by mail or e-mail. Statistical processing was analyzed using SPSS 25.0 and AMOS 25.0 statistical packages. As a result of the verification, the relationship between the image and attachment of food tourism, the relationship between the long-term orientation in the attachment of traditional food, and the behavioral intention in the attachment of traditional food are significant. A significant positive (+) relationship was formed in the relationship of hypothesis setting according to the research purpose of the relationship.
