  • 본 논문에서는 UML 클래스 저작도구를 위한 메타데이터의 정보를 구축하고 처리하는 방법을 제시하고자 한다. 저작도구의 메타데이터 정보 구축은 UML의 클래스 다이어그램을 구성하는 요소들 바탕으로 클래스 (Class)와 관계 (Relationship)를 정의한다. 클래스의 정보 정의는 클래스의 가시성과 클래스의 이름과 클래스의 속성 그리고 클래스의 오퍼레이션이다. 관계의 정보 정의는 관계의 이름과 관계의 유형과 시작클래스 그리고 도착 클래스이다. 본 논문에서 제시하는 클래스 저작도구를 위해 구축된 정보를 바탕으로 정보 저장소에서 정보를 저장하는 방법과 불러오는 방법을 제시한다.

  • 현재 정밀도로지도 구축 공정은 수작업의 비율이 높아 구축 시간과 비용의 한계가 따른다. 인공지능을 이용하여 정밀도로지도 제작을 자동화하기 위한 연구가 활발하게 진행되고 있으나 정밀도로지도 제작을 위한 학습데이터의 구축 또한 수동으로 이루어지고 있어 학습데이터를 자동으로 구축할 필요성이 있다. 이에 본 연구에서는 모바일매핑시스템으로 취득한 포인트 클라우드를 이용하여 영상으로 변환한 후, 임계치를 이용한 영상 재분류와 중첩 분석 등을 통해 도로 노면표시 영역을 추출하고 추출한 영역의 다각형 유형 분류를 통해 정밀도로지도 제작을 위한 딥러닝 학습데이터를 자동으로 구축하는 방법론을 제안하였다. 제안한 방법론을 통해 구축한 2,764개의 차선 데이터를 딥러닝 기반의 PointNet 모델에 학습한 결과 학습 정확도는 99.977%로 나타났으며, 학습된 모델을 이용하여 3가지 색상 유형의 차선을 예측한 결과 정확도는 99.566%로 나타났다. 따라서, 본 연구에서 제안한 방법론으로 정밀도로지도 구축을 위한 학습데이터를 효율적으로 제작할 수 있는 것을 알 수 있었으며, 도로 노면표시의 정밀도로지도 제작과정 또한 자동화할 수 있을 것으로 사료된다.

  • We here investigate the Liouville type theorems of slow diffusion differential inequality and its coupled system with variable coefficients in cone. First, we give the definition of global weak solution, and then we establish the universal estimate (does not depend on the initial value) of solution by constructing test function. At last, we obtain the nonexistence of non-negative non-trivial global weak solution within the appropriate critical exponent. The main feature of this method is that we need not use comparison theorem or the maximum principle.

  • Purpose: This paper was written to introduce methods of using the research ethics committee (RES) from requesting the initial review to reporting the close-out for nursing researchers. Methods: General ethical principles were described by reviewing the 'Bioethics and Safety Act' and other related guidelines, and constructing some questions and answers. Results: The results were composed of three parts; definition of RES, steps in using RES, and archiving. The 7 steps for using RES were; identifying whether the study needed to be reviewed, by the RES identifying whether the study could be exempted, requesting the initial review after preparing documents, requesting the re-review, requesting an amendment review, requesting a continuing review and reporting the close-out. Conclusion: Nursing researchers need to receive RES approval before starting nursing research involving human subjects. Nursing researchers are urged to use the steps reported in this paper to receive RES approval easily and quickly.

  • In this paper, we present a robust global registration algorithm for multi-frame image mosaics. When we perform a pair-wise registration recovering a projective transformation between two consecutive frames, severe mis-registration among multiple frames, which are not consecutive, can be detected. It is because the concatenation of those pair-wise transformations leads to global alignment errors. To overcome those mis-registrations, we propose a new algorithm using multiple frames for constructing image mosaics. We use a graph to represent the temporal and spatial connectivity and show that global registration can be obtained through the search for an optimal path in the constructed graph. The definition of an adequate objective function characterizing the global registration provides a direct manipulation of the graph. In the presence of moving objects, especially large ones compared with low texture backgrounds, by using the likelihood ratio as the objective function, we can deal with some of the most challenging videos like basketball or soccer Moreover, the algorithm can be parallelized so it can be more efficiently implemented. Finally, we give some experimental results from real videos.

  • This paper presents a feature recognition system for recognizing and extracting feature information needed for machining from design data contained in the CAD database of AutoCAD system. The developed system carries out feature recognition from an orthographic view of a press mold containing not only atomic features such as holes, pockets, and slots, but also compound features. Based on the result of feature recognition, it generates a 3-D modeling of the press mold. Especially, The feature recognition part is designed for detecting feature styles according to feature definition and classification, extracting parameters for various atomic features, and constructing necessary data structures for the recognized features.

  • The book number, among various steps of book processing works, needs more careful attention and better-organized knowledge, and it is more sensitive than other parts of cataloging. This paper will give some suggestions on ways of constructing a book number, including the definition and the types of edition indication within a book number, and analyse some problems related to their application into real situation. Three possible ways of edition indication with in a book number were explained, and examples were given for each of them. Problems occurring when these codes were applied to books were analysed. In addition to the generally recognized meaning of the book number as a mean of differentiating similar works, the edition indication can make it possible for both the library staffs and the users to identify the characteristics of a work only with the book number. Searches for mere convenient and effective ways of edition indication might be related to the cost-effectiveness of book processing, and of library operation.

  • The paradigm of mobile communication technology has changed from an increase in transmission capacity to service-based technologies satisfying various types of service requirements. One of the new paradigms is a service that provides users with a QoE (Quality Of Experience (QoE), at anytime and anywhere. 5G defines various technologies such as dense network structures and beam selection for increasing the transmission capacity and ensuring the quality of experience so as to satisfy this requirement, and related research is underway. In this paper, we describe the definition of a 5G small cell and 5G network structure as well as research trends of standardization and related technologies for constructing optimal solutions for mobile users in dense networks based on small cells.

  • The purposes of this study were to conceptualize the Home Meal Replacement (HMR) in Korea and to gather professionals' opinions of prospect and task for HMR industry in Korea. A total of 67 experts participated in a three round survey by Delphi technique, which was used to integrate and share the each expert's professional idea. According to the result, HMR was translated into 'Gajeongsiksa daeyongsik' in Korean and given definition to 'a meal taken directly or through brief cooking process at home by purchasing ready to eat or ready to end-cook type of food'. As the result of categorizing HMR products of Korean food, 'I. Ready to eat' such as side dishes, kimchi, salad, sandwich, kimbab, and so on and 'II. Ready to heat' such as rice, porridge, retort food (soup, broth, curry, spaghetti, etc.), frozen pizza, grilled food, jabchae, instant soup, and so on were construed in a limited sense of the HMR. In addition, 'III. Ready to end-cook' such as frozen dumpling, frozen pork cutlet, seasoned meat, powder-type soup, and so on as well as these two kinds were interpreted in a broad sense of the HMR. In the prospect of HMR industry in Korea, the Korean HMR industry would develop continuously accompanied by increasing of consumers using HMR products. Introduction and generalization of HMRs would serve the convenience for meal preparation and then influence the change of home meal pattern. Nevertheless, it was concerned about that using HMRs might have limitation on solving the problems of dietary life including irregular meal, skipping a meal, and so on and influence the nutrition imbalance. For the development of HMRs, developing various menu and the packaging materials for HMR products, constructing the thorough sanitary management, and strengthening R & D for the HMR of Korean food were the future tasks in Korean HMR industry.
