생성형 모델 기반 이미지 변환 성능 향상을 위한 프롬프트 자동화 연구
김민석,김민석 한국멀티미디어학회 2025 멀티미디어학회논문지 Vol.28 No.2
Recent generative models are widely applied across various industries, with particular attention to text-to-image (T2I) and text guided image-to-image (TI2I) models in the field of image generation. TI2I models aim to preserve the structural characteristics of source images while applying semantic transformation based on prompt. However, existing methods rely on user prompts, leading to inconsistent results depending on the user’s proficiency and writing style. To address this issue, this paper proposes an automated prompt expansion system using Large-Language Model (LLM) to generate structure descriptions of source images. This approach ensures prompt consistency and mitigates structural distortion and semantic bias when performing TI2I using Stable Diffusion-based DDPM inversion.

The leaching of zinc oxide by NH4Cl solution was studied using the factorial design method to determine the effects of major leaching parameters. Analysis of experimental results suggested that the effective parameters were concentration of NH4Cl solution, solid/liquid ratio, leaching temperature, and interactions between them. Based on the results, a model equation for the leaching was suggested by which 96% of leaching behavior could be explained. The residual analysis revealed that the precipitation of Zn(NH3)2Cl2 tends to induce the lack-of-fit of the model. The precipitation of Zn(NH3)2Cl2 was reduced by raising pH of leaching solution properly. This suggests that the problems which may occur by the precipitation of Zn(NH3)2Cl2 could be prevented effectively. 실험계획법을 이용하여 염화암모늄용액에 의한 산화아연의 침출에 대한 연구를 수행하였으며 주요 침출변수들의 영향을 조사하였다. 실험결과의 분석으로부터 염화암모늄의 농도, 고/액 비, 침출온도 및 기타 교호작용 등이 유효한 인자로 나타났으며, 이로부터 침출거동의 96%를 설명할 수 있는 침출모델식을 얻을 수 있었다. 또한 일정 경향성을 보이는 잔차 분석으로부터 침출반응 후 용액의 온도 저하에 의해 생성되는 Zn(NH3)2Cl2 침전이 침출모델의 적합결여(Lack-of-Fit)을 유발하는 것임을 알 수 있었다. Zn(NH3)2Cl2 침전의 생성은 침출액의 pH를 적절히 높임에 따라 감소하였으며, 이는 Zn(NH3)2Cl2 침전에 의한 아연전해회수 등 후속 공정에서의 문제발생을 효과적으로 예방할 수 있음을 의미한다.

결혼이주여성의 사회적경제 참여를 통한 인정자본의 축적과 교환 과정에 대한 연구: 글로벌레이디협동조합과 (주)오디에스의 사례를 중심으로

This study intends to address the issues of mutual recognition and coexistence of diversity between two ethnic groups. First, the function of ritual in Durkheim’s sociology of religion is discussed. The social economy is viewed as an important mechanism for community formation. Second, the process by which recognition is accumulated and exchanged is viewed as Bourdieu's theory of capital transformation and classification. Accumulated recognition is closely related to the three forms of capital. The case of Global Lady and ODS shows that recognition between two workers can be accumulated in the form of capital. In the former case, bilingual-related rituals induce accumulation of capital of recognition. It appeared in the form of cultural and social capital. In the latter case, cultural commodity-related rituals induce the accumulation of capital of recognition. It is mainly in the form of cultural and economic capital. The researcher made the following suggestions. First, the institutional support for the accumulation of capital of recognition. between the two targets in a social economy organization is strengthened. Second, the current status of migrant participation in the social economy field and the arrangement of basic data. Third, the social economy education and promotion of two people is strengthened.
