인터넷의 발전으로 인터넷을 통해 미디어 콘텐츠를 제공하는 OTT 서비스의 이용자가 점점 증가하고 있다. 본 논문에서는 OTT 서비스 이용자의 검색 편의성을 위한 Vision API를 활용한 영상 속 랜드마크 검색 시스템을 제안한다. 이는 영상을 시청하는 사용자가 영상을 보다가 궁금한 장소가 있으면 따로 검색하지 않고, 바로 해당 장소의 정보를 얻도록 하는 것이다. 본 논문에서 개발한 영상 속 랜드마크 검색 시스템은 사용자가 원하는 영상을 검색 및 재생할 수 있고 재생 중 바로 화면을 캡처할 수 있다. 해당 캡처 이미지를 랜드마크를 기계 학습한 Vision API를 통해 어떤 랜드마크인지 파악하고 결과를 표시한다, 또한 동일 영상에서 다른 사용자가 검색한 이력이 있는 경우 이력을 표시하여주며, 검색한 랜드마크가 나온 다른 영상을 검색하여 보여준다.

In this paper, we present a transformation method of source code from a POSIX (Portable Operating System Interface) based source code into an OSEK/VDX (Offene Systeme und deren Schnittstellen fur die Elektronik in Kraftfahrzeugen/Vehicle Distributed eXecutive) source code. As the electronic parts of automobile systems increase, the use of embedded software in automobile systems is also growing. Accordingly, many electronic systems are designed in automobile system with OSEK/VDX. Otherwise, one of the major problems of embedded software would be portability to other OS's. To enhance the portability and interoperability of embedded software, we propose a source code transformation method from POSIX to OSEK/VDX based on API (Application Programming Interface) translation method. Considering the characteristics of the OSEK/VDX which uses OIL (OSEK/VDX Implementation Language) standard, transformation process is performed with source code transformation and OIL code generation. For the validity of the proposed method, the transformation experiment is given using Micro-C OS II and OSEK/VDX with XC167CI micro-controller.

Intelligent Transportation Systems (ITS) is aimed to implement IT(Information Technology) to develop the next-generation transportation system in order to improve traffic conditions. In order to provide traffic information, the methods that provide available traffic informations to the public are needed. In this paper, analysis of the transportation applications in smart-phone and currently available methods of traffic information's sharing and providing were discussed. Finally, OPEN API was discussed and shows its effectiveness for transportation information area especially in smart phone.

As unmanned processing systems emerged socially due to the rapid development of modern society, a face recognition attendance management system using Raspberry Pi 4 was studied and conceived to automatically analyze and process images and produce meaningful results using OpenCV. Based on Raspberry Pi 4, the software is designed with Python 3 and consists of technologies such as OpenCV, Haarcascade, Kakao API, and Google Drive, which are open sources, and can communicate with users in real time through Kakao API for face registration and face recognition.

Residents near the fire site are more anxious as they rely only on media information and the government's evacuation order due to the lack of information to understand the progress of the wildfire. Therefore, in the event of a wildfire, we try to understand the inconvenience of not being able to know the progress of the fire and solve it. This makes it possible to check the progress of wildfires and the spread of debris using the system interface (API) and weather data of the thermal infrared satellite image data (NASA FIRMS, Fire Information for Resource Management System), and finally, the purpose of this study. The results are provided through the Web including GIS-based visualization to provide decision-making reference information for evacuation in the event of a forest fire from the perspective of residents.

Recently, it is reported that the Korean Unmanned Aerial Vehicle (UAV) interface protocol (K-4586) based on STANAG-4586 is being developed to secure interoperability between UAVs. The core elements of the K-4586-based Unmanned Aircraft System (UAS) are the Core UAV Control System (CUCS), Vehicle Specific Module (VSM), Data Link Interface (DLI), and C4I systems. In UAS based on K-4586, the DLI function for transmitting and receiving messages to link UAVs is included in VSM and CUCS respectively. The Generator/Analyzer (G/A) tool is an apparatus that is developed for protocol conformance verification for VSM and CUCS, and G/A tools with DLI message transmitting and receiving should be developed separately. Core applications (VSM, CUCS, DLI) and G/A tools based on K-4586 may be developed independently depending on the developers. If the DLI message modules are different for each developer, the scope and results of protocol conformance verification will be dissimilar, and some problems may happen during system integration. In this study, common DLI message module based on the API was designed to provide the DLI message transmitting and receiving function necessary to the development of core applications and the protocol conformance verification tool of based on K-4586. When applying the proposed common DLI message module, it can be expected to shorten the UAS system development period and reduce costs, and ensure conformance of protocol. In this paper, the design and implementation method for the common DLI message module based on API was proposed and the results of functional test was described.

The one of the biggest challenges in using e-mail is that it is difficult to filter out unconfirmed senders. Therefore, in this study, an email group authentication API was designed using blockchain technology, which has been widely used as an authentication method. As the proposed model, the node-node weighting index was obtained through the relationship association network, and after designing the email reliability model, the reliability calculation model of the Rotten Tomato method was obtained. Based on this, the system structure was designed, chain code methods were defined, and API was developed. Through this study, it is expected that it will be used in various fields requiring authentication as well as email user authentication, and it is expected that the relationship of group authentication can be proved by allowing a large number of users to use the API in the future.
