After the US government declared 3D printing technology a next-generation manufacturing technology, there have been many practical studies conducted to expand 3D printing technology to manufacturing technologies, called AMERICA MAKES. In particular, the Keck Center, located at the University of Texas at El Paso, has studied techniques for easily combing the 3D stacking process with space mobility and expanded these techniques to simultaneous staking techniques for multiple materials. Additionally, it developed convergence manufacturing techniques, such as direct inking techniques, in order to produce a module structure that combines electronic circuits and components, such as CUBESET. However, in these studies, it is impossible to develop a unified system using traditional independent through simple sequencing connections. This is because there are many problems in the integration between the stacking modeling of 3D printers and post-machining, such as thermal deformations, the precision accuracy of 3D printers, and independently driven coordinate problems among process systems. Therefore, in this paper, the integration method is suggested, which combines these 3D printers and subsequent machining process systems through an Internet-based cloud. Additionally, the sequential integrated system of a 3D printer, an NC milling machine, machine vision, and direct inking are realized.

With advances in sensor technology, current researches on the pertinent techniques are actively directed toward the way which enables the USN computing service. For many applications using sensor networks, the incoming data are by nature characterized as high-speed, continuous, real-time and infinite. Due to such uniqueness of sensor data characteristics, for some instances a finite-sized buffer may not accommodate the entire incoming data, which leads to inevitable loss of data, and requirement for fast processing makes it impossible to conduct a thorough investigation of data. In addition to the potential problem of loss of data, incoming data in its raw form may exhibit high degree of complexity which evades simple query or alerting services for capturing and extracting useful information. Furthermore, as traditional mining techniques are developed to handle fixed, static historical data, they are not useful and directly applicable for analyzing the sensor data. In this paper, (1) describe how three mining techniques (sensor data outlier analysis, sensor pattern analysis, and sensor data prediction analysis) are appropriate for the USN middleware structure, with their application to the stream data in ocean environment. (2) Another proposal is a middleware structure based on USN environment adaptive to above mining techniques. This middleware structure includes sensor nodes, sensor network common interface, sensor data processor, sensor query processor, database, sensor data mining engine, user interface and so on.

애니메이션에서 캐릭터 움직임은 과장되고 코믹하게 표현되어 진다. 전통적인 키 프레임 애니메이션 기법은 과장성과 코믹성이 애니메이터의 의향대로 조절 가능하지만, 근래에 도입된 모션캡처 기법은 대상의 자연스러운 모습을 담아내어 편리하다는 장점이 있지만 과장성과 코믹성의 표현에는 제약점이 있다고 알려져 있다. 본 논문은 키 프레임과 모션캡처를 사용한 애니메이션 작품 중 두 작품을 선정하여 캐릭터의 움직임과 동작을 분석하여 과장성과 코믹성이 어떻게 표현되고 있는지 살펴보고자 한다. 기본적인 동작요소인 달리기, 점프, 제스처, 걷기와 그 외의 움직임으로 분류하여 두 가지 작품에서 캐릭터의 동작을 비교하여 보고 그 표현 방식을 분석한다. 각각의 작품에서 보이는 움직임의 유사성과 차이성을 살펴보면서 키 프레임과 모션캡처 애니메이션 제작 기법의 장단점을 내재된 과장성과 코믹성 측면에서 논의한다. 그리고 이 두 가지의 애니메이션 제작 기법을 이용한 캐릭터들의 움직임의 차이점을 분석한 결과, 각각 움직임에 공통적인 차이점이 존재한다는 것을 알 수 있다.

Precast concrete elements are widely used in the construction of buildings and civil infrastructures as they provide higher construction quality and requires less construction time. However, any abnormalities in precast concrete surfaces such as non-flatness or distortion, can influence the erection of the elements as well as the functional performance of the connections between elements. Thus, it is important to undertake surface flatness and distortion inspection (SFDI) on precast concrete elements before their delivery to the construction sites. The traditional methods of SFDI which are conducted manually or by contact-type devices are, however, time-consuming, labor-intensive and error-prone. To tackle these problems, this study proposes techniques for SFDI of precast concrete elements using laser scanning technology. The proposed techniques estimate the $F_F$ number to evaluate the surface flatness, and estimate three different measurements, warping, bowing, and differential elevation between adjacent elements, to evaluate the surface distortion. The proposed techniques were validated by experiments on four small scale test specimens manufactured by a 3D printer. The measured surface flatness and distortion from the laser scanned data were compared to the actual ones, which were obtained from the designed surface geometries of the specimens. The validation experiments show that the proposed techniques can evaluate the surface flatness and distortion effectively and accurately. Furthermore, scanning experiments on two actual precast concrete bridge deck panels were conducted and the proposed techniques were successfully applied to the scanned data of the panels.

This study was purpose to method that applies for improving the image quality in CT and X-ray scan, especially in the lung region. Also, we researched the parameters of the image before and after applying for Histogram Equalization (HE) such as mean, median values in the histogram. These techniques are mainly used for all type of medical images such as for Chest X-ray, Low-Dose Computed Tomography (CT). These are also used to intensify tiny anatomies like vessels, lung nodules, airways and pulmonary fissures. The proposed techniques consist of two main steps using the MATLAB software (R2021a). First, the technique should apply for the process of normalization for improving the basic image more correctly. In the next, the technique actively rearranges the intensity of the image contrast. Second, the Contrast Limited Adaptive Histogram Equalization (CLAHE) method was used for enhancing small details, textures and local contrast of the image. As a result, this paper shows the modern and improved techniques of HE and some advantages of the technique on the traditional HE. Therefore, this paper concludes that various techniques related to the HE can be helpful for many processes, especially image pre-processing for Machine Learning (ML), Deep Learning (DL).

This paper offers a brief introduction to Vietnamese folk paintings. The discussion compares Vietnamese folk paintings with the Korean folk painting tradition. Among the main purposes of this paper is the exploration of directions for future research on Vietnamese folk paintings. Vietnamese folk paintings, although extensively influenced by their Chinese tradition of minjian nianhua (folk New Year pictures), form an independent tradition, reflecting the local lifestyle and religious practices of Vietnam. However, compared to Korea or Japan, China remains the dominant source of influence for Vietnamese folk paintings. They were either created using a combination of painting and woodblock printing techniques, which was also the case with minjian nianhua, or using multicolor woodblock printing techniques. In cities like Hang Chong, the combination of painting and woodblock printing techniques was used mainly, following the customary practice in Yangliuqing in Tianjin, China, in which colors were added to the drawing printed from the woodblock. Meanwhile, folk paintings produced in rural areas such as Dong Ho are wholly color woodblock prints, similar to minjian nianhua from Yangjiabu in Weifang. In Lang Sinh, simple drawings, intended for casual purposes, were also created using the combination of woodblock printing and painting techniques. Folk paintings produced in cities and rural areas were distinct from each other, not just in techniques, but also in terms of style and theme. Vietnamese folk paintings show a certain degree of thematic similarity with Joseon folk paintings. This is mainly due to the fact that the two countries' folk paintings developed and evolved in parallel with their Chinese counterparts, minjian nianhua. Also noteworthy is the fact that Vietnamese folk paintings, while they share the simplicity and candidness of Joseon folk paintings, are at the same time somewhat more decorative than the latter. For best results, future research on Vietnamese folk paintings should be conducted together with research on minjian nianhua. Traditional pigments constitute an important area of research in this field. Attention should be also paid to the religious paintings of ethnic minorities in Vietnam, as they are discovered in the future.

Methods for calculating k shortest paths in a network system, are based on a analogy which exists between the solution of a network problem and traditional techniques for solving linear equations. This paper modifies an algebraic structure of the K shortest path method and develops k maximum flow methods. On the basis of both theoretical and algebraic structure, three iteration methods are developed and the effective procedure of each method are provided. Finally, computational complexity is discussed for those methods.
