Due to the development of science and technology, diversity of fusion technologies has become a major concern. Especially the application of the convergence education became necessary in the curriculum of engineering department. The purpose of this paper is to extract characteristics of convergence education among engineering majors and to present a model of applicable convergence education. The researchers collected studies of past 15 years in domestic and international journals in related themes. Academic research information systems, DBpia, e-article, Academic Search Complete were used for keyword searches. 43 Korean papers and 25 international papers were analyzed for the study. The results showed that the convergence education models for college of engineering can be classified into the three types: the cooperative convergence, multidisciplinary convergence, and transdisciplinary convergence. Based on the results, a convergence education model is suggested for the schools of engineering in Korea.

Carbon-coated Ni, Cu and Sn nanocapsules were investigated by means of X-ray diffraction (XRD), transmission electron microscopy (TEM) and a four-point probe device. All of these nanocapsules were prepared by an arc-discharge method, in which the bulk metals were evaporated under methane ($CH_4$) atmosphere. Three pure metals (Ni, Cu, Sn) were typically diverse in formation of the carbon encapsulated nanoparticles and their different mechanisms were investigated. It was indicated that a thick carbon layers formed on the surface of Ni(C) nanocapsules, whereas a thin shell of carbon with 1~2 layers covered on Cu(C) nanocapsules, and the Sn(C) nanocapsules was, in fact, a longger multi-walled carbon nanotubes partially-filled with metal Sn. As one typical magnetic/dielectric nanocomposite particles, Ni(C) nanocapsules and its counterpart of oxide-coated Ni(O) nanocapsules were compared in the electrically conductive behaviors for further applications as the electromagnetic materials.

We research a system of compressed-sensing computational ghost imaging (CSCGI) based on the intensity fluctuation brought by turbulence. In this system, we used the gamma-gamma intensity-fluctuation model, which is commonly used in transmission systems, to simulate the CSCGI system. By setting proper values of the parameters such as transmission distance, refractive-index structure parameter, and sampling rates, the peak signal-to-noise ratio (PSNR) performance and bit-error rate (BER) performance are obtained to evaluate the imaging quality, which provides a theoretical model to further research the ghost-imaging algorithm.

Novel soluble triazoleimide oligomers terminated with arylacetylene terminated were synthesized by the Cu(I)-catalysed 1,3-dipolar cycloaddition polymerization of diazides and imide-containing dialkyne. Several molecular weight triazoleimide oligomers were prepared from diazide and dialkyne monomers with different stoichiometric combinations. The curing behaviors of the oligomers were tested by differential scanning calorimetry (DSC). The thermal properties of the cured products were evaluated by DSC and thermogravimetric analysis (TGA). These cured oligomers showed the glass transition temperature of about $225-235^{\circ}C$ and the decomposition temperature (at 5% weight loss) of about $385-393^{\circ}C$ in nitrogen.

With the rapid development of domestic and international over-the-top markets, a large amount of video content is being created. As the volume of video content increases, consumers tend to increasingly check data concerning the videos before watching them. To address this demand, video summaries in the form of plot descriptions, thumbnails, posters, and other formats are provided to consumers. This study proposes an approach that automatically generates posters to effectively convey video content while reducing the cost of video summarization. In the automatic generation of posters, face recognition and clustering are used to gather and classify character data, and keyframes from the video are extracted to learn the overall atmosphere of the video. This study used the facial data of the characters and keyframes as training data and employed technologies such as DreamBooth, a text-to-image generation model, to automatically generate video posters. This process significantly reduces the time and cost of video-poster production.

Trajectory prediction is an essential element for driving autonomous vehicles, and various trajectory prediction models have emerged with the development of deep learning technology. Convolutional neural network (CNN) is the most commonly used neural network architecture for extracting the features of visual images, and the latest models exhibit high performances. This study was conducted to identify an efficient CNN backbone model among the components of deep learning models for trajectory prediction. We changed the existing CNN backbone network of multiple-trajectory prediction models used as feature extractors to various state-of-the-art CNN models. The experiment was conducted using nuScenes, which is a dataset used for the development of autonomous vehicles. The results of each model were compared using frequently used evaluation metrics for trajectory prediction. Analyzing the impact of the backbone can improve the performance of the trajectory prediction task. Investigating the influence of the backbone on multiple deep learning models can be a future challenge.

The education system is the communication field should be based on the characteristics of communication science and the function of manpower. However, the current education system at the level of college is insufficient and irrational to meet the requirements of the telecommunication field in our country. The main reasons are as follows: 1. Misunderstanding the characteristics of communication science. 2. Indiscretion of the categories of communication manpower due to lack of coordination between academic circles and communication industrial field. Telecommunication function could be performed only by combining the engineering and the suitable operational control. The communication engineering is similar to the electronic engineering, but the former should follow the miscellaneous international protocol and the domestic regulations, being only a means for the telecommunication function. In order to improve the education system of communiation, we aim to identify the principle of communication science, orthodoxy of the education, the categories of communication industrial field and manpower. The present system has been formed on the basis of ignoring the attributes of manpower and historical background of communication science. Therefore, this paper proposes to set up new departmental organizations for educating communication manpower as the following: In addition, this paper proposes a new curriculum model of the above twodept, and we believe that it well turn out more scientific, effective and reasonable education for the communication science. 1. Modification of the present formation, designated Electronic Communication Department. 2. New formation model: A. The best future model such as establishing ad independent telecommunication college which is composed of : Dept. of Radiocommunication Dept. of Telecommunication Enginnering Dept. of Communication Industrial management Dept. of Transmission Engineering Dept. of Telecommunication Law B. An immediately practicable proposal model instead of the existin Dept.. which is composed of the first two Dept. of the above five Dept. In addition, this paper proposes a new curriculum model of the above two dept. and we believe that it will turn out the education for the communication science to be more scientific, effective and reasonable.

This study presents how two types of integrated science and engineering lessons affect students' engineering problem solving skills and their perceptions of engineering. In total, 146 middle school students participated in this study. Eighty-six students participated in the Type I lesson (complete engineering design lesson with a science knowledge application) and 60 students participated in the Type II lesson (engineering design without a science knowledge application). Two main datasets, (1) students' Creative Engineering Problem Solving Propensity (CEPSP) measurement scores and (2) open-ended survey questions about students' perceptions of engineering, were collected before and after the lessons. The results of this study show that after participating in the Type I lesson, students' CEPSP scores significantly increased, whereas the CEPSP scores of the students who participated in the Type II lesson did not increase significantly. In addition, students who participated in the Type I lesson perceived engineering and the engineering integrated science lesson differently compared to the students who participated in the Type II lesson. The results of this study show that engineering integrated science, technology, engineering & mathematics (STEM) lessons should include a complete engineering design and a science knowledge application to improve students' engineering problem solving skills.
