The prolonged of the Post Corona made many industry's paradigm. It's become very important In the industries products that customers directly touch and use. To cope with this situation, The Cosmetics industry has recently introduced various untact services. many customers would like to try these new services. Typically, online survey services recommend personalized products. but these services reached its limit later. This paper research how to recommend products and define skine type with AI Image diagnosis module combine with legacy survey system.

In this paper, we developed a system that intelligently identifies skin image data from big data collected from social media Instagram and extracts standardized skin sample data for skin condition diagnosis and management. The system proposed in this paper consists of big data collection and analysis stage, skin image analysis stage, training data preparation stage, artificial neural network training stage, and skin image identification stage. In the big data collection and analysis stage, big data is collected from Instagram and image information for skin condition diagnosis and management is stored as an analysis result. In the skin image analysis stage, the evaluation and analysis results of the skin image are obtained using a traditional image processing technique. In the training data preparation stage, the training data were prepared by extracting the skin sample data from the skin image analysis result. And in the artificial neural network training stage, an artificial neural network AnnSampleSkin that intelligently predicts the skin image type using this training data was built up, and the model was completed through training. In the skin image identification step, skin samples are extracted from images collected from social media, and the image type prediction results of the trained artificial neural network AnnSampleSkin are integrated to intelligently identify the final skin image type. The skin image identification method proposed in this paper shows explain high skin image identification accuracy of about 92% or more, and can provide standardized skin sample image big data. The extracted skin sample set is expected to be used as standardized skin image data that is very efficient and useful for diagnosing and managing skin conditions.

사용자의 피부 관리 및 피부질환을 검사하는 기존의 어플리케이션은 유도 질문에 따른 사용자의 응답을 기반으로 결과를 유추하기 때문에 부정확한 진단 결과를 야기한다. 본 논문에서는 사용자의 미용관련 피부질환 이미지를 바탕으로 딥러닝 이미지 인식 기술 적용하여 건선, 사마귀, 여드름, 한포진을 대상으로 피부 미용질환에 대한 식별 정보를 제공하는 어플리케이션을 제시한다. 또한 이미지 인식률이 높은 ResNet과 SE-ResNet 알고리즘을 적용하여 피부질환 식별 적용 시 효과성을 실험적으로 비교한다.

Diagnosis and management of skin condition is a very basic and important function in performing its role for workers in the beauty industry and cosmetics industry. For accurate skin condition diagnosis and management, it is necessary to understand the skin condition and needs of customers. In this paper, we developed SCIS, a big data-based skin care information system that supports skin condition diagnosis and management using social media big data for skin condition diagnosis and management. By using the developed system, it is possible to analyze and extract core information for skin condition diagnosis and management based on text information. The skin care information system SCIS developed in this paper consists of big data collection stage, text preprocessing stage, image preprocessing stage, and text word analysis stage. SCIS collected big data necessary for skin diagnosis and management, and extracted key words and topics from text information through simple frequency analysis, relative frequency analysis, co-occurrence analysis, and correlation analysis of key words. In addition, by analyzing the extracted key words and information and performing various visualization processes such as scatter plot, NetworkX, t-SNE, and clustering, it can be used efficiently in diagnosing and managing skin conditions.

As the aging population grows, the incidence of cancer is increasing. Skin cancer appears externally, but people often don't notice it or simply overlook it. As a result, if the early detection period is missed, the survival rate in the case of late stage cancer is only 7.5-11%. However, the disadvantage of diagnosing, serious skin cancer is that it requires a lot of time and money, such as a detailed examination and cell tests, rather than simple visual diagnosis. To overcome these challenges, we propose an Attention-based CNN model skin cancer classification system. If skin cancer can be detected early, it can be treated quickly, and the proposed system can greatly help the work of a specialist. To mitigate the problem of image data imbalance according to skin cancer type, this skin cancer classification model applies the Over Sampling, technique to data with a high distribution ratio, and adds a pre-learning model without an Attention layer. This model is then compared to the model without the Attention layer. We also plan to solve the data imbalance problem by strengthening data augmentation techniques for specific classes.

본 연구에서는 고압산소치료 후 포유동물의 피부에서 Melanin 세포의 생성이 줄어들었음을 이미 보고된 바 있고, 치료 후 전층 피부이식 생존율을 높였고, 또한 인체의 피부 진피층 확인은 더 많은 임상데이터가 필요하나 고압산소치료 후 표피면의 변화는 빠른 시간에 확인 할 수 있다고 판단됨으로 이에 피부진단기의 기준면과의 평행(parallel polarization) 이미지로 피부표피의 변화를 확인 하고자 했다. 본 연구의 고압산소챔버를 활용한 피부표피에 대한 분석 및 실험 결과, 주름살 및 상처(Wrinkle & Scar) 분석에서 피실험자 남자1 3%, 남자2 2%, 여자1 5.9%, 여자2 2.3%로 피실험자 모두 감소 현상을 보여 피부 탄력도가 좋아 지는 효과를 보였다. 피부미백(S-Gray) 분석에서는 피실험자의 피부 표피면의 멜라닌 및 에리즈마 색소의 피부 톤이 남자1 1.1%, 남자2 2.3%, 여자1 4% 로 피실험자 4명 중 3명은 상승 효과를 얻었으나, 피실험자 다른 1명인 여자2는 2.3% 하향의 결과가 나타났다. 홍도(Erythema) 분석, 피실험자 정상인 부위인 D.BLUE/BLUE 값이 남자1 5.6%, 남자2 4.9%, 여자1 17.3%, 여자2 15.3% 증가 현상을 보였으며 남자와 여자의 효과 차이가 10% 이상으로 나타낸 것으로 보아 남자 보다는 여자가 우세한 것으로 판단되었으며, 비정상인 에리즈마 색소(민감도)의 비정상인 부위인 YELLOW/RED 컬러 값에서 남자1 5.2%, 남자2 5%, 여자1 9.2%, 여자2 4.5% 감소 하였음을 보였다. 이에 피실험자 모두 에리즈마인 민감성 산소치료에 따른 피부에 미치는 영향이 효과가 있는 것으로 판명되었다.

The skin is the body's first line of defense against external infection. When a skin disease strikes, the skin's protective role is compromised, necessitating quick diagnosis and treatment. Recently, as artificial intelligence has advanced, research for technical applications has been done in a variety of sectors, including dermatology, to reduce the rate of misdiagnosis and obtain quick treatment using artificial intelligence. Although previous studies have diagnosed skin diseases with low incidence, this paper proposes a method to classify common illnesses such as warts and corns using a convolutional neural network. The data set used consists of 3 classes and 2,515 images, but there is a problem of lack of training data and class imbalance. We analyzed the performance using a deep metric loss function and a cross-entropy loss function to train the model. When comparing that in terms of accuracy, recall, F1 score, and accuracy, the former performed better.

Optical Coherence Tomography (OCT) is a non-invasive imaging method that utilizes the optical scattering and interference for visualizing the surface as well as cross-sectional structures of tissue. OCT has been used for diagnosing diseases in early stage in various medical fields, but an application in cosmetics is still at early stage. In this study, OCT was adopted to evaluate skin texture and wrinkle. Results showed similar patterns of evaluation with PRIMOS in the assessment using replica. In addition, OCT produced smaller errors at different angles compared to the PRIMOS in the assessment using 3-dimensional models of wrinkles. The resolution of the image was also high enough to differentiate the images of before and after the application of makeup products. Possible use of OCT in the evaluation of fine wrinkle assessment was studied in this research. Further development of methods is necessary to provide more evidences of the effectiveness.
