The purpose of this study is to develop and validate a scale to measure the ethical awareness of users who accept artificial intelligence technology or service. To this end, the constructs and properties of AI ethics were identified through literature analysis on AI ethics. Reliability and validity were assessed through a preliminary survey(N=273), after conducting an open-type survey to men and women(N=133) in 10s to 70s nationwide, extracting the first questions, and reviewing them by experts. The results of an online survey conducted on men and women(N=500) were refined by confirmatory factor analysis. Finally, an AI technology ethics scale was developed. The AI technology ethics awareness scale was developed with 16 questions in total of 4 factors (transparency, safety, fairness, accountability) so that general awareness of ethics related to AI technology can be measured by detailed factors. In addition, through follow-up research, it will be possible to reveal the relationship with measurement variables in various fields by using the ethical awareness scale of artificial intelligence technology.

The purpose of this study is to develop the multi-modal interaction system. This system provides realistic and an immersive experience through multi-modal interaction. The system recognizes user behavior, intention, and attention, which overcomes the limitations of uni-modal interaction. The multi-modal interaction system is based upon gesture interaction methods, intuitive gesture interaction and attention evaluation technology. The gesture interaction methods were based on the sensors that were selected to analyze the accuracy of the 3-D gesture recognition technology using meta-analysis. The elements of intuitive gesture interaction were reflected through the results of experiments. The attention evaluation technology was developed by the physiological signal analysis. This system is divided into 3 modules; a motion cognitive system, an eye gaze detecting system, and a bio-reaction sensing system. The first module is the motion cognitive system which uses the accelerator sensor and flexible sensors to recognize hand and finger movements of the user. The second module is an eye gaze detecting system that detects pupil movements and reactions. The final module consists of a bio-reaction sensing system or attention evaluating system which tracks cardiovascular and skin temperature reactions. This study will be used for the development of realistic digital entertainment technology.

오늘날 운영체계와 미들웨어는 수많은 API를 제공하고 있다. 최종 사용자들이 사용하는 응용 프로그램들은 이러한 API를 활용하여 개발되어지고 있다. 기존의 문서와 같은 형태의 API에 대한 기술은 기계가 자동적으로 처리하기 힘들며 개발자 입장에서도 API를 이해하기 위해서 책을 직접 읽고 이해해야 한다는 단점이 있다. 이를 극복하기 위하여 docgen과 같은 도구들이 있으나 결국은 개발자 관점에서는 API를 직접 숙지하여야 하며 응용 프로그램 상에서 직접 운영체계에서 제공하는 API 호출 부분을 작성하여 개발하여야 한다는 부분은 동일하다. 또한 서로 다른 다양한 운영체계에서는 형식은 다르지만 유사한 기능을 제공을 하는 API들이 있으나 개발자는 특정 운영체계의 API에 맞추어서 각각의 운용체계에 맞는 응용 프로그램을 개발하여야 하는 문제점이 있다. 본 연구에서는 API에 대한 정보에 대한 규격을 정의하고 각각의 API의 기능 및 특성에 대하여 메타 기술언어를 사용하여 기술하여 저장소에 저장해두고 실행시에 이러한 API정보를 사용하여 응용 프로그램과 동적으로 바인딩시켜서 실행시키는 체계에 대해서 논의한다. 응용 프로그램에서 사용하려고 하는 API와 운영체계에서 제공하는 API를 동적으로 결합시키는 엔진에서는 운영체계별 API의 차이에 의한 부분을 상쇄시키는 역할을 담당한다. 이러한 체계를 활용하면 동적으로 재구성 가능한 응용을 개발하는데 있어서 하부 시스템으로 활용될 수 있다. 향후 표준 API를 기술하는데 있어서도 본 연구에서 제시하는 메타 방식의 API 기술표현을 활용하면 보다 정확한 표준 규약 준수 여부를 확인할 수 있는 방법을 제공할 수 있다.

The most of public services that we use these days is distributed and supplied as 'App' service because of wide spread of smat phones. Especially, since the interest of general citizens about usabilitu of public data has been increased, in case of Seoul, people can reach the data through 'Seoul Open Data Plaza' of 25 regions of Seoul. It becomes possible to construct various throughout this system. Ultimately, in case of users, they are provided many services through their electronic media. Looking at the development and research of public data service, they are mostly focusing on service or building up the service, but the research on visualization of contents is insufficient. This study is suggesting the specific plan and directionality of building public service using the public data which studied in the advanced research, "The user interface platform". Finally. this research is for a right usage of public data in the smart urban environment in near future and providing the practical public service.

Recently, with a rapidly growing of the mobile content market, a variety of mobile-based applications are being launched. But mobile devices, compared to the average computer, take a lot of effort and time to get the final contents you want to use due to the restrictions such as screen size and input methods. To solve this inconvenience, a recommender system is required, which provides customized information that users prefer by filtering and forecasting the information.In this study, an tailored multi-information recommendation system utilizing a Personalized information recommendation system on smartphone is proposed. Filtering of information is to predict and recommend the information the individual would prefer to by using the user-based collaborative filtering. At this time, the degree of similarity used for the user-based collaborative filtering process is Euclidean distance method using the Pearson's correlation coefficient as weight value.As a real applying case to evaluate the performance of the recommender system, the scenarios showing the usefulness of recommendation service for the actual restaurant is shown. Through the comparison experiment the augmented reality based multi-recommendation services to the existing single recommendation service, the usefulness of the recommendation services in this study is verified.

In order to develop color image, color simulation based on data processing techniques has been developed and applied to data interpretation tools or product design supporting systems. It has been a commonmethod to use image key words to search for data and provide color coordination samples that determine computer combination in computerized support systems until recently. However, this method does not reflect system designers and users taste or preference on making final choices of color coordination samples because the database was designed based on an assumption of standardized group that was established database from large scaled image evaluation research. In this study, we suggest a color coordination simulator that supports designer's final decision-making procedure on sample groups through the simulation of various color combination. The simulator allows communications with the system to explore a designer's color combination taste and preference, and provides a user for an efficient environment to judge the optimum result. The color coordination simulator was designed based upon Dual mapping model derived from a designer's thought process, and four steps of operations longrightarrowdefining color concept longrightarrowmaking color sample groupslongrightarrow simulation-determining ranking among final combination samples - will be assisting color design process.

환경오염으로 인해 아토피 등의 피부질환이 증가하고 있으며 이에 국내에서는 인터넷을 통한 아토피 진단 서비스는 많다. 하지만 단순한 설문조사 형식으로 진단에 대한 객관성을 유지하기 어려워 신뢰도가 낮다. 이에 본 논문은 컴퓨터 비전 인식 기술을 활용하여, 컴퓨터에서 처리가능한 아토피 환자의 환부 영상을 수집 및 진단하는 시스템을 개발한다. 아토피 진단 시스템은 환부 영상을 사용자로부터 입력받아 색상값에 대한 히스토그램을 만들어 정규화한다. 다음으로 정규화된 히스토그램의 확률적 분포를 이용해 역투영한 결과 영상을 만들어 내게 되며 이 역투영 영상을 바탕으로 피부색을 제외한 부분을 아토피 침범 영역이라 판단하게 된다. 최종적으로는 입력 영상으로부터 얻어진 침범 영역, 문진을 이용한 점수를 이용하여 SCORAD 지수 스코어링 하게 된다.
