This paper develops fashion products that express the beauty of Baekje through an investigation of the unique characteristics of Baekje artifacts. This work can promote the Baekje region and provide cultural goods for local festivals to improve the economic competitiveness of the area. Artifacts from the Muryongwangreung in Gongju (the capital city of Baekje during the Woongjin period)were reinterpreted into a more modern form. Among the Muryongwangreung artifacts, the king and queen's gold coffin as well as chignon ornaments were used as design motifs. These artifacts were stylized into motifs and developed into patterns using Adobe Illustrator CS3 and Adobe Photoshop CS3. The patterns were subsequently applied to the designs of scarves and ties. The color was selected using the CMYK colorway from the Gongju city logo subsequently, a total of 12 designs (including 6 ties and 6 scarves) were developed. The design developed from this research can be applied to diverse products to promote the area. Using the research as a foundation, fashion product development based on the local culture can have a significant impact on the establishment of the Baekje cultural identity and the competitiveness of the region.

This paper proposes an interconnect delay fault test (IDFT) solution on boards and SoCs based on IEEE 1149.1 and IEEE P1500. A new IDFT system clock rising edge generator which forces output boundary scan cells to update test data at the rising edge of system clock and input boundary scan cells to capture the test data at the next rising edge of the system clock is introduced. Using this proposed circuit, IDFT for interconnects synchronized to different system clocks in frequency can be achieved efficiently. Moreover, the proposed IDFT technique does not require any modification of the boundary scan cells or the standard TAP controller and simplifies the test procedure and reduces the area overhead.

This paper proposes a Distributed Autonomous Robotic System(DARS) based on an Artificial Immune System(AIS) and a Classifier System(CS). The behaviors of robots in the system are divided into global behaviors and local behaviors. The global behaviors are actions to search tasks in environment. These actions are composed of two types: aggregation and dispersion. AIS decides one among these two actions, which robot should select and act on in the global. The local behaviors are actions to execute searched tasks. The robots learn the cooperative actions in these behaviors by the CS in the local. The proposed system is more adaptive than the existing system at the viewpoint that the robots learn and adapt the changing of tasks.

Busan Metropolitan City runs Community Health Center which aims to health care service based on the community, besides the established health medical service towards people with low-income. 71 centers are run in 2021, therefore, this papear explores the way of digital transition of these centers. Digital Technologies possibly adopted inside the centers are: First, smart devices to advance the management system of chronical diseases based on health index; Second, IoT with mobile tech to manage health index; Third, AI Robot to care lone elderly people and to warn the emergency.

This study examined the effects of simulation-based practice on competence and satisfaction in nursing students. We collected the data from 189 4th grade nursing students. Simulation-based practice was conducted from August 28th to November 27th, 2015. The collected data were analyzed by SPSS 21.0 program. As the result of simulation-based practice, significant improvement was found in competence (t=-14.42, p<.001) and satisfaction($4.53{\pm}.58$). Simulation-based practice can help students to improve their overall abilities in clinical practices and increase their satisfaction in result. Therefore we suggest that more systematic and continual simulation-based practice should be applied in nursing education.

This study analyzes the academic achievement of students how much they are related to both NCS(national competency standards)-based education from university and the learning motives(internal motive, external motive) of the students based on current university students. For this study, a survey was conducted among 200 employees and are summarized as follow. First, that both internal and external motives to study were significant to have a good effect on academic achievement of students. Second, NCS-based education to have positive effect on academic achievement.

오늘날 멀티미디어 정보의 양이 매우 빠른 속도로 증가함에 따라 멀티미디어 데이타베이스에 대한 효율적인 관리는 더욱 중요한 의미를 가지게 되었다. 게다가 영상과 같은 비 문자형태의 데이타에 대한 사용자들의 내용기반 검색욕구 증가로 인해 비디오 인덱싱에 대한 관심은 더욱 고조되고 있다. 따라서 본 논문에서는 우선적으로 분할된 샷 경계면에서 추출된 대표 프레임과 정지 영상 데이타베이스로부터 유사 영상과 유사 대표 프레임을 검색할 수 있는 환경을 제공한다. 우선적으로 영상에 의한 질의는 기존에 주로 사용되어온 색상 히스토그램방식을 탈피하여 본 논문에서 제안하는 CS와 GS방식을 이용하여 색상 및 방향성 정보도 고려하도록 설계하였다. 또한 얼굴에 의한 질의는 대표 프레임으로부터 얼굴 영역을 추출해 내고 얼굴의 경계선 값 및 쌍 직교 웨이블릿 변환에 의해 얻어진 2개의 특징값을 이용하여 유사 인물이 포함된 대표 프레임을 검색해 내도록 설계하였다. Abstract There is a rapid increase in the use of digital video information in recent years, it becomes more important to manage multimedia databases efficiently. There is a big concern about video indexing because users require content-based image retrieval. In this paper, we first propose query-by-image system environment which allows to retrieve similar images from the chosen representative frames or images from the image databases. This algorithm considers not only the discretized color histogram but also the proposed directional information called CS & GS method. Finally, we designe another query environment using query-by-face. In this system , user selects a people in the representative frame browser and then system extracts a face region from that frame. After that system retrieves similar representative frames using 2 features, edge information and biorthogonal wavelet transform.

Civil aircraft noise certification standard is based on the ICAO Annex 16 Vol. 1. And, the standard uses A-Weighted SPL, EPNL and SEL method depending on the aircraft category. Korean noise standards, KAS 36 and other nation's CS 36 and FAR 36 noise standards were developed and revised according to the international noise standards, ICAO Annex 16. And, the national noise requirements are equivalent each other. The small airplane noise certification requires only take-off noise level with A-Weighted SPL in dB(A) unit. The first Korean aircraft noise certification was performed for the KC-100 certification in August 2012 with Korean authority and U.S. FAA. The noise certification requires much knowledge and experience in flight tests and noise data processing. In this study, the noise test requirements, test conditions and data correcting methods are shown with the test examples.

A new broadcasting signal transmission, which can save its channel bandwidth using compressive sensing(CS), is proposed in this paper. A new compression technique, which uses two dimensional discrete wavelet transform technique, is proposed to get high sparsity of multimedia image. A L1 minimization technique based on orthogonal matching pursuit is also introduced in order to reconstruct the compressed multimedia image. The CS enables us to save the channel bandwidth of wired and wireless broadcasting signal because various transmitted data are compressed using it. A $256{\times}256$ gray-scale image with compression rato of 20 %, which is sampled by 10 Gs/s, was transmitted to an optical receiver through 20-km optical transmission and then was reconstructed successfully using L1 minimization (bit error rate of $10^{-12}$ at the received optical power of -12.2 dB).

Compressive sensing (CS) has to face with two challenges of computational complexity reconstruction and low coding efficiency. As a solution, this paper presents a novel spatially scalable Kronecker two layer compressive sensing framework which facilitates reconstruction up to three spatial resolutions as well as much improved CS coding performance. We propose a dual-resolution sensing matrix based on the quincunx sampling grid which is applied to the base layer. This sensing matrix can provide a fast-preview of low resolution image at encoder side which is utilized for predictive coding. The enhancement layer is encoded as the residual measurement between the acquired measurement and predicted measurement data. The low resolution reconstruction is obtained from the base layer only while the high resolution image is jointly reconstructed using both two layers. Experimental results validate that the proposed scheme outperforms both conventional single layer and previous multi-resolution schemes especially at high bitrate like 2.0 bpp by 5.75dB and 5.05dB PSNR gain on average, respectively.
