  • 3D modeling is extensively used in the field of architecture, machinery and contents production such as movies. Modeling is a time-consuming task. In order to compensate for these drawbacks, attempts have recently been made to reduce the production period by applying 3D scanning technology. 3D scanning for small objects can be done directly with laser or optics, but large buildings and sculptures require expensive equipment, which makes it difficult to acquire data directly. In this study, 3D modeling data for a large object is acquired using photometry with using drones to acquire the image data. The maintenance method for uniform spacing between the sculpture and the drone, the measurement method for the flight line were presented. In addition, we presented a production environment that can utilize the obtained 3D point cloud data for animation and a rendered animation result to find ways to make it in various environments.

  • Hankyong National University decided to introduce a track-based curriculum for a curriculum innovation as it switched a Polytechnic University system into a general University system. A TF(task force) team was formed to study a operation strategy of a track curriculum and the opinions of campus members and educationist were gathered. Such systematic preparation was performed for the introduction of the track. Based on those works, a track-based curriculum has been operating from 2012 spring semester. A track system defines that the curriculum in a department is divided into specific majors(or tracks) and the department/agency guarantees their expertise if the students complete the course of a specific major to increase the depth and expertise in the field of study or specific areas. Track means a set of customized courses that are demanded by the corporations, and the courses include basically specific education activities, levels of education, and educational contents required for job or position of the corporation. In this paper, any issues, that arose through the operations of the track-based curriculum at Department of Electrical, Electronic and Control Engineering in Hankyong National University, and their possible solution were presented.

  • For browsing, searching, and manipulating video documents, an indexing technique to describe video contents is required. Until now, the indexing process is mostly carried out by specialists who manually assign a few keywords to the video contents and thereby this work becomes an expensive and time consuming task. Therefore, automatic classification of video content is necessary. We propose a fully automatic and computationally efficient method for analysis and summarization of spots news video for 5 spots news video such as soccer, golf, baseball, basketball and volleyball. First of all, spots news videos are classified as anchor-person Shots, and the other shots are classified as news reports shots. Shot classification is based on image preprocessing and color features of the anchor-person shots. We then use the dominant color of the field and motion features for analysis of sports shots, Finally, sports shots are classified into five genre type. We achieved an overall average classification accuracy of 75% on sports news videos with 241 scenes. Therefore, the proposed method can be further used to search news video for individual sports news and sports highlights.

  • The Army's engineers are carrying out a range of operations using various equipment, of which, artillery unit support is the representative engineering operation field. The main task of the artillery unit is to attack the enemy's center with firepower from the rear of a friendly force. The artillery must move its original position after firing several times to prevent exposure of the shooting position. This paper proposed a mathematical model and heuristic algorithm that can be used to determine the optimal allocation among engineer equipment, the team (work), and position while reflecting the constraints of the construction of an artillery position. The model proposed in this paper derived the optimal solution for the small size problems, but it takes a long time to derive the optimal solution for the problem of equipment placement of the engineer battalion and brigade scale. Although the heuristic suggested in this study does not guarantee the optimal solution, the solution could be obtained in a reasonable amount of time.

  • Simulation of the trans-oceanic or trans-basin propagation of a tsunami is a computer-intensive task. This study demonstrates an effective and detailed visualization technique to deal with the vast amount of surface-elevation and velocity-field output. This high-definition visualization technique is used to present simulations of the 1960 and 2010 Chilean earthquake tsunamis and the 1983 Central East (Japan) Sea earthquake tsunami. This tsunami-visualization method using high-definition graphic animation is an appropriate tool to show detailed tsunami-propagation behavior over an ocean or coastal sea, as exemplified by the Pacific Ocean and East (Japan) Sea tsunami events.

  • As the number of medical disputes regarding nurses has increased after medical disputes have increase, there is a need for a study on it. However, the legal relationship between nurses and patients has not yet been analyzed. Recently, the role and function of nurses are expanded according to the development of the science of nursing; moreover their activity and limitation of responsibility are also expanded. For this reason, the medical disputes regarding nurses have been increasing. However, the majority of these kind of dispute are just passed over because their practice is usually considered to be a mere action to assist doctor's role. In addition, nurse practice is not a secondary action of doctor's role, but forms part of a medical treatment. Of course, nurses handle many secondary tasks after doctors finish their medical treatment. But this is only part of the whole tasks of nurses. Furthermore, the general details of their medical treatment are not different from those of doctors because they also belong to the medical service personnel. Considering these features of nurse and the medical condition in South Korea, their task is becoming increasingly developed and specialized and they are also establishing their own field. With this stream of times, there is a growing interest in enacting a Nursing Practice Act, in other words, the independent law on nurse for the sake of patient safety and national health promotion. Then, their responsibility will distinctly be expanded as much more. That is, the time that nurses practice their medical care by following doctors' order and also pass over their responsibility to doctors is closed. Thus, this study examines the features and responsibilities of nursing practice, and discusses an institutional framework to efficiently cope with the legal disputes between nurses and patients. It aims to throw light on the decision making on nurse-patient disputes in future.

  • It is well-known that non-metric digital cameras have to be calibrated for the close-range photogrammetry. But, the self-calibration is still not an easy task because it requires rather a large calibration site of accurate control points, multiple image acquisitions in different positions, and accurate image point measurements that are quite labor-intensive and time-consuming. Based on the premise, this study carried out check point accuracy analysis from self-calibration of different control point designs and photo combinations. The test results showed that the calibration using three photos covering three-dimensional control points produced high accuracy, but control points on a plane could attain the comparable accuracy with four photos including a 90-degree rotated photo. We then compared the target accuracy of on-site self-calibration using flat control points to that of laboratory-self calibration and observed comparable results.

  • Flight of an autonomous unmanned aerial vehicle (UAV) generally consists of four steps; take-off, ascent, descent, and finally landing. Among them, autonomous landing is a challenging task due to high risks and reliability problem. In case the landing site where the UAV is supposed to land is moving or oscillating, the situation becomes more unpredictable and it is far more difficult than landing on a stationary site. For these reasons, the accurate and precise control is required for an autonomous landing system of a UAV on top of a moving vehicle which is rolling or oscillating while moving. In this paper, a vision-only based landing algorithm using dynamic gimbal control is proposed. The conventional camera systems which are applied to the previous studies are fixed as downward facing or forward facing. The main disadvantage of these system is a narrow field of view (FOV). By controlling the gimbal to track the target dynamically, this problem can be ameliorated. Furthermore, the system helps the UAV follow the target faster than using only a fixed camera. With the artificial tag on a landing pad, the relative position and orientation of the UAV are acquired, and those estimated poses are used for gimbal control and UAV control for safe and stable landing on a moving vehicle. The outdoor experimental results show that this vision-based algorithm performs fairly well and can be applied to real situations.

  • In the modem society, people try to represent and protect their traditional arts in aesthetic way along with the global society. The proposal of this thesis is about the fashion illustration that has adopted the folklike formative arts. 1 prefer the formative character rather then the universal character and I would like to use of folk paintings far the fashion illustration. Because the formative character of folk paintings is very expressional, we are able to draw a fashion illustration in easy, new, creative and less difficult way. The fashion illustration has to be a specialized field from the formative arts, and we need to study in a new way as well. We draw fashion illustration through the understanding of folk paintings and the study of analysis in formative. As a result of this study, we could draw a fashion illustration which is very abstract, exaggerative and simple. We also could expect the free hand drawing lines on this illustration. In these fashion illustrations, the human bodies let us fret the artists' tense, speed, and power. According to the important character of folk painting, which is the beauty of color, these fashion illustrations have expressed more color intensive. In the falk paintings there is a kind of rules to make color order, so the fashion illustrations that we drew have the bright and clear color combination. Because the folk paintings shouldn't be the artistic but should be the realistic, the fashion illustrations concentrate on the real subject. It is very natural looking that use the natural dyes in the fashion illustrations. According to this kind of art task, fashion illustration will be a certain part of the illustration in the modem society.
