위성데이터를 활용한 시계열 데이터는 다양한 분야에서 변화 탐지와 모니터링에 필수적인 자료로 활용되고 있다. 시계열 데이터 생성에 관한 선행 연구에서는 데이터의 통일성을 유지하기 위해 주로 단일 영상을 기반으로 분석하는 방식이 사용되었다. 또한 공간 및 시간 해상도 향상을 위해 다종 영상을 활용하는 연구도 활발하게 진행되고 있다. 시계열 데이터의 중요성은 계속해서 강조되지만, 데이터를 자동으로 수집하고 가공하여 연구에 활용하기 위한 산출물은 아직 제공되지 않고 있다. 따라서 이러한 한계를 극복하기 위해 본 논문에서는 사용자가 설정한 지역의 위성정보를 자동으로 수집하고 시계열 데이터를 생성하는 기능을 제안한다. 본 연구는 한 종류의 위성영상뿐만 아니라 동일 지역의 여러 위성데이터를 수집하고 이를 시계열 데이터로 변환하여 산출물을 생성하는 것을 목표로 하며, 이를 위한 위성영상 자동 수집 시스템을 개발하였다. 이 시스템을 활용하면 사용자는 관심 있는 지역을 설정함으로써 해당 지역에 맞게 데이터가 수집되고 Crop되어 즉시 활용할 수 있는 데이터를 생성할 수 있다. 실험 결과로는 웹 상에서 무료로 제공되는 Landsat-8/9 OLI 및 Sentinel-2 A/B 영상의 자동 획득이 가능함을 확인하였으며, 수동 입력을 통해 별도의 고해상도 위성영상도 함께 처리할 수 있었다. 고해상도 위성영상을 기준으로 자동 수집 및 편집된 영상 간의 정확도를 비교하고 육안 분석을 수행한 결과, 큰 오차 없이 결과물을 생성할 수 있음을 확인했다. 이후 시계열 데이터 간 상대적 위치 오차 최소화 및 좌표가 획득되어 있지 않은 데이터 처리 등에 대한 연구 및 다양한 위성영상을 활용한 시계열 데이터 생성 기능 추가가 계획되어 있다. 위성영상을 활용한 시계열 데이터의 생성 방법이 정립되고, 국토위성, 농림위성과 같은 국내 위성정보를 이용한 시계열 데이터가 효과적으로 활용될 경우, 국토·농림·산업·해양 분야에서 다양한 응용 가능성이 기대된다.

In the 21st century, the dualistic worldview of the Cold War era collapsed and we entered an era of new creation and fusion. The fusion of different designs between East and West, the design activities of traditional clothing from the past, the use of new materials that are continuously being developed, and the mixing of unique items are being conducted in various fields. However, research is being conducted by combining fusion characteristics with hair. In addition, the period is short and the amount of research is small. Therefore, this study analyzed hairstyles of fusion images shown in hair collection using data of Juno Hair collection from 2013 to 2022 as analysis data and examined types of fusion images shown in the work of folk images, mixed images, and future images. Oriented images were divided into three categories and analyzed. In this study, we added Results of such research can be used not only as data for predicting future fashion trends, but also as basic data for exploring new design developments. In future research, it is expected that convergent research will be conducted, such as analyzing fusion images from an integrated perspective.

The purpose of this study is to find out the image according to formative properties of hat and garment in the fashion collection. For the study, the 96 stimuli found frequently in fashion collection from the S/S season of 1998 to the F/W season of 2004 were selected. Sets of stimulus and response scales (7 point semantic) were used as experimental materials. The stimuli were 96 pictures with the types of hat(4), the lengths of hair(3), the types of garment(3), the relations between the color of garment and hat(4), and the materials(4) and patterns of garment(2). The subjects were 415 women college students majoring fashion design related fields and living in Seoul and Gyeongsangnam-do. As statistical methods for data analysis, Factor Analysis, ANOVA test, and LSD test were used. The items of the adjectives were classified into 5 image dimensions; attractiveness, gracefulness, concentration, cuteness, and hardness and softness. Among these factors, each dimensional image was affected by formative properties of hat and garment. The image of a hat-wearer was perceived differently according to the hair style and the formative properties of hat and garment even if the type of hat was same.

As the 4th industrial era is in full swing, the public's interest in related technologies such as artificial intelligence, big data, and block chain is increasing. As artificial intelligence technology is used in various industrial fields, the need for research methods incorporating artificial intelligence technology in related fields is also increasing. Evidence collection among digital forensic investigation techniques is a very important procedure in the investigation process that needs to prove a specific person's suspicions. However, there may be cases in which evidence is damaged due to intentional damage to evidence or other physical reasons, and there is a limit to the collection of evidence in this situation. Therefore, this paper we intends to propose an artificial intelligence-based evidence collection system that analyzes numerous image files reported by citizens in real time to visually check the location, user information, and shooting time of the image files. When this system is applied, it is expected that the evidence expected data collected in real time can be actually used as evidence, and it is also expected that the risk area analysis will be possible through big data analysis.
