This paper introduces a digital image processing(DIP) method as a method for measuring the displacement of pylon. The comparison of DIP results and ANSYS analysis results verified the validity of the image processing technique. Normalized cross-correlation(NCC) coefficient was used and experiments were performed three times. It shows that the displacement difference was 22% and 5% compared to ANSYS results. Therefore, the image processing method is expected to be able to measure the displacement of pylon sufficiently.

Deposits discharged through the cleaning mainly were cement mortar, bitumen paintings and rust pieces, and fragments of perforation, stones and gravels. Deposits were more removed through swabbing pig cleaning rather than air scouring cleaning on the whole. However, air scouring cleaning were not influenced by the constraint conditions such as a change in the diameter or the presence of the valve in water mains compare to swabbing pig cleaning. So, it was thought that air scouring cleaning might be more favorable to water distribution network cleaning in the future. After the cleaning, water quality including residual chlorine and turbidity also was improved because of the removal of a significant amount of the deposits. Therefore, if the cleaning is continuously and regularly implemented in water mains, it is expected that it will help to recover the reliability and to preserve the health of water quality.

The Commission for Conservation of Antarctic Marine Living Resources (CCAMLR) is utilized to manage krill resources using acoustic data collection and a scientific observer program operating on the fishing boats. However, the acoustic data were contained seriously noise, example of background, spike, and intermittent noise, due to purpose of fish boats. In this study, the noise removal techniques were confirmed the potential of the acoustic data analysis. Acoustic system and frequency used in the survey were commercial echosounder (ES70, SIMRAD) and 200 kHz split beam transducer. Acoustic data were analyzed using Echoview software (Myriax), and general data analysis and new noise removal method was used. Although a variety of noise, most of the noises have been removed using the noise removal processing. We confirmed the possibility of analyzing the acoustic data obtained from fish boats. The results will be useful for analysis of the acoustic data acquired from krill fishing boats.

The process of Apparel Product Development requires several major steps such as Pattern Digitizing, Grading, Marker Making, and Cutting Out. The current operation for Pattern Digitizing is conducted operators who amend apparel patterns on a computer after digitizing them based on a point-input method. The current process is laborious, time-consuming, and expensive due to error-prone work that leaves much to be desired in solution expansion. These studies develop an automated system for apparel pattern input based on vectorising technique. Supporting industrial standardization (the detailed targets for the system development) minimizes the involvement of operators and include: automatic recognition of pattern domain, automatic recognition of sample shape, and inner part recognition performing apparel characteristic function. The following picture shows an example using our system developed with a women bra pattern. Figure 2 represents women a bra pattern Figure 3 represents data implemented on the automated system we developed The results of our study : 1. Analytical speed: under 4 seconds in resolution 150 dpi, image size A3. 2. Length error: under 0. 2mm. 3. Outline: 100% extract of outlines cutting and marker pattern. 4. Pattern elements: classification automatically and editing available by user. 5. Pattern division: try one acting scanning various pattern. 6. Data entry/output: converting of DXF, AAMA, TIP, DIGIT. We developed an automated system based on vectorising software for implementation of apparel patterns. The cost of effective system repeatedly processes digitizing tasks with high quality in a few minutes. The system will contribute to the apparel industry field by implementing automatic steps for recognition and classification pattern.

In the age of hybrid, the fashion industry has created multiple patterns of hybrid fashion due to mixed styles and genres. Fashion mixed with tradition and future and various cultures is emerging as a trend so that Asian cultures are reinterpreted in a modern way(Samsung Design Net. 2014). Korean images also change every year into a new type of cultural hybrid. This study aims to present esthetic and trendy hybrid outer wear designs applicable to the fusion of tradition and present and the west and the east as well as diverse life styles for the major target of consumption, the senior generation with young sense. This study conducted both theoretical and empirical study. The theoretical study looked into the characteristics of digital fashion illustrations using Sumuk technique and of senior outer wear through the precedent study and literature. In the empirical study, fashion illustrations were made according to the characteristics of digital fashion illustrations with Sumuk technique, and then fabric was made through digital printing. By doing so, hybrid outer wear designs for the senior generation were developed based on the characteristics of senior outer wear, and the real artwork was made. The findings are as follows. First, the characteristics of digital fashion illustrations using Sumuk technique are the hybrid expression where the spirit of inner feeling of oriental thinking, implications of symbolism and metaphor through blanks and lines, and fortuity of ink blurs and lines are recreated in a modern way through digital fashion illustration characteristics such as hybridity of multi-cultures and heterogeneous factors, expandability of blurring boundary, human-oriented playfulness, and sensibility of inner expression. Second, outer wear for the senior generation puts the most emphasis on aesthetic factors including designs, styles, youth, and complement of figure, followed by symbolism such as convenience of dressing or undressing, comfort, functionality of flexible size, trend, express of individuality, and dignity. In addition, this generation prefers outdoor wear for social, cultural, and casual activities and demand hybrid city wear designs adding the characteristics of outdoor wear that is highly worn for various city life styles. Third, the design motifs of fabric made by digital printing of Sumuk technique-based digital fashion illustrations include traditional ornaments of Joseon Dynasty such as norigae(Korean traditional ornaments worn by women), binyeo(Korean traditional ornamental hairpin), and ddeoljam(ornamental hairpin), mix traditional and Korean spirit with modern sensibility, and connote esthetic beauty of ornamental effects for women’s beauty and symbolism of lucky signs and wishes. Fourth, senior outer wear was designed using the made fabric. Work 1 arranged prints with the motif of traditional norigae in a spaced pattern. Hybrid outer was designed with comfortable, light, and reversible functions by using A line silhouette considering the senior generation’s figure, single buttons for easy clothing change, and outdoor wear materials and highlighted the utilization of city wear. Work 2 used border pattern of fashion illustration prints that use binyeo as its motif, and it was designed for social and cultural life styles with the fusion of tradition, which uses tent silhouette durumagi(traditional Korean outer coat) and composition lines that are plane and straight lines, and modernism. It highlighted functionality by using zippers and single buttons for each clothing changing and outdoor materials. Work 3 arranged fashion illustrations made by the motif of ddeoljam in a spaced pattern. This is a balloon silhouette considering the senior generation’s figure and a urban, modern design with unbalanced hem line with asymmetry of light and left. A zipper was attached, and a light and flexible outdoor material was used to emphasize its functionality. Work 1, 2, and 3 made the fabric of cultural hybrid sense using Sumuk technique-based digital fashion illustrations and used the design considering the senior generation’s figure and an outdoor material, and expressed easy clothing change and design of city wear. This is a hybrid senior fashion design expressing the fusion and coexistence of traditional and modern beauty, Korea’s oriental beauty and modern western beauty, and outdoor wear’s functionality and city life styles. This study will contribute to the invigoration of the senior fashion market that is newly emerging and the development of high-value added products as it presents hybrid outer wear adding functionality applicable to various life styles for the senior generation with the young sense.

This paper aimed at modeling a fine triangular grid for network dome by using Harmony Search (HS) algorithm. For this purpose, an optimization process to find a fine regular triangular mesh on the curved surface was proposed and the analysis program was developed. An objective function was consist of areas and edge's length of each triangular and its standard deviations, and design variables were subject to the upper and lower boundary which was calculated on the nodal connectivity. Triangular network dome model, which was initially consist of randomly irregular triangular mesh, was selected for the target example and the numerical result was analyzed in accordance with the HS parameters. From the analysis results of adopted model, the fitness function has been converged and the optimized triangular grid could be obtained from the initially distorted network dome example.

This work introduces a modal testing and analysis results of the mock-up for a layered stone pagoda. The pagoda has been horizontally excited by an impact hammer. As to the measured acceleration time responses, the first five lower mode shapes and natural frequency are extracted by the TDD technique. It is observed that the time delay of a shear wave occurs through friction surfaces. Such phenomena cannot be described by using the traditional analytical models such as a continuum cantilever beam model or a discrete shear building model. However, the time delay typically affects only the phases of the pagoda system. The frequencies of the pagoda system are not affected by such time delay. It is found in the first time that the layered stone pagoda system has a set of closely placed modes in near of natural frequency. It is believed that such modes are due to the friction characteristics in friction surfaces. Based on the stick-slip friction model, it seems that the one of the closely placed mode can be a self-excited one.

BWIM 시스템의 개발을 위해 차량 주행시험은 필수적이지만 그 비용과 시간이 많이 소요되고, 다양한 차량 주행 조건의 적용이 어렵다. 따라서 차량 주행시험의 비용 및 시간적 문제점을 보완하고, 주행 조건에 따른 다양한 교량응답의 확보할 수 있는 수치 시뮬레이션이 현장실험과 병행되어야한다. 본 연구에서는 교량의 동적특성을 반영하는 수치 시뮬레이션을 수행하여 교량의 응답을 획득하고, 통행 차량의 중량을 산출하는 BWIM 시스템에 적용하여 총중량 및 축중량 추정을 수행하고 정밀해석모델기반 과적단속기술에 대하여 제안하였다.

목 적 : 경추 척수 손상 부위와 정도를 평가하는 데 DTI 기법은 현재 많은 임상적 연구가 진행되고 있으나 spinal cord를 영상화 하는데 제한점이 있다. DTI 기법 중 2D ss-DWEPI에 IMIV(Interleaved Multisection Inner Volume) 방법을 접목한 2D ss-IMIV-DWEPI 기법은 위상 부호화 방향으로 공간적 범위를 감소하여 자화율 왜곡과 motion artifact 등을 줄이고 진단 시 병변 감별능을 높일 수 있다. 본 논문은 DTI 기법 사용 시 2D ss-DWEPI에서 IMIV 기법을 적용 할 때와 기존 2D ss-DWEPI에서의 rFOV변화에 따른 FA 값과 ADC 값을 비교하고 영상의 질을 평가하여 IMIV 기법사용 시 DTI 기법의 유용성을 평가하고자 한다. 대상 및 방법 : 2013년 12월부터 2014년 1월까지 cervical spine 검사 시 DTI sequence를 적용한 환자 10명을 대상으로 3.0T MR(Trio, Siemens Healthcare, Erlangen, Germany) 장비를 사용하였다. 코일은 phased-array spine coil과 neck coil을 사용하였다. DWEPI DTI는 TR/TE: 4000/65ms, FOV: 192mm, slice thickness: 2mm without gap, matrix: 128×32, 64, 128(rFOV 25%, 50%, 100%), NEX: 8을 사용하였다. 또한 ss-IMIV-DWEPI는 위와 같은 조건으로 matrix 128×32(rFOV 25%)를 사용하였으며 두 기법 모두 slice 수 10개, b factor 0, 500s/mm² 적용하였다. 영상 측정은 두 기법 모두 sagittal 영상을 얻어 cervical C1에서 T1까지 각각의 척추디스크 사이에 ROI를 그려 ADC, FA signal intensity를 측정하여 정량적 분석을 하였고 2개 segment (C1∼C5, C5∼T1)로 나누어 영상의 motion artifact, distortion, 병변 검출 능력을 평가하여 정성적 분석을 하였다. 결 과 : ADC와 FA의 signal intensity를 측정한 평균값은 ADC에서 IMIV 560.7, rFOV100% 1261.3, rFOV50% 1387.3, rFOV25% 1321.9 로IMIV의 ADC 값이 가장 작게 나타났으며 IMIV를 적용하지 않을 경우 rFOV50%에서 1387.3로 가장 높게 나타났다. FA에서는 IMIV 623.1, rFOV100% 578.7, rFOV50% 544.5, rFOV25% 495.7로 IMIV의 FA값이 가장 크게 나타났다. ADC에서 IMIV와 rFOV25, rFOV50, rFOV100의 p-value는 statistical significant가 모두 0.05 이하였다. FA에서도 pvalue는 statistical significant가 모두 0.05 이하였다. IMIV를 적용하지 않은 경우 rFOV 변화에 따른 값들 모두 유의한 값을 얻었다. 정성적 평가는 방사선사 5명이 영상을 관찰하고 motion artifact, distortion, 병변 검출 능력 등의 전체적인 영상의 질을 점수화하여 5명의 점수를 평균화 하였다. ADC에서는 IMIV 기법을 적용한 경우 upper/lower spine segment 모두 3.8-4.8 사이의 높은 점수를 받았으며 rFOV25, rFOV50, rFOV100에서는 lower spine segment에서 1.2-2.0 사이의 낮은 점수를 받았음을 확인 할 수 있었다. FA에서는 IMIV 기법을 적용한 경우가 upper/lower spine segment에서 3.6-4.6 사이의 점수를 받았으며 rFOV25, rFOV50, rFOV100에서 1.4-1.8 사이의 점수를 받았다. 결 론 : 3.0T MRI Cervical spine 검사에서 small FOV DTI 사용 시 IMIV-DWEPI 기법을 사용한 DTI는 기존 DWEPI에 비해 긴 검사 시간을 가지고 있지만 motion artifact, distortion 등의 제약에서 비교적 자유로우며 영상에서의 병변 검출 능력이 우수하므로 임상적 이용에 있어 많은 도움이 될 것이라고 판단된다.

목 적 : 신호대 잡음비는 자기공명영상 장치의 성능과 영상의 질을 평가하기 위한 객관적인 정보를 제공하는 중요한 척도이며 이를 측정하기 위한 많은 방법들이 제안되고 있다. 그 중 두 영역 측정방법은 측정방법이 간단하고 시간이 짧기 때문에 가장 흔히 사용되고 있다. 본 연구에서는 다중채널코일과 병렬영상기법 적용 시 두 영역측정방법에 의해 산출된 신호대 잡음비의 정확성에 대해 알아보고자 하였다. 대상 및 방법 : 장비는 Philips 3.0T MRI(Achieva, Philips medical system, Netherlands)과 transmit receive head coil, SENSE 8 channel head coil을 사용하였으며 MR sequence는 spin echo T1, T2 강조영상을 사용하여 축상면으로 ACR phantom 영상을 획득하였다. Transmit receive head coil을 사용한 두 영역 측정방법, AAPM, NEMA, Philips에서 제안한 측정방법, 다중채널코일과 병렬영상기법 적용 시 두 영역 측정방법의 신호대 잡음비 측정 조건에 따라 T1, T2 강조영상을 각각 30번씩 획득하였으며 Image J를 사용하여 각 영상의 동일한 위치에서 ROI 크기를 10 mm2으로 하여 신호대 잡음비를 측정하였다. 결 과 : T1 강조영상의 경우 AAPM에서 제안한 방법이 가장 균일한 신호대 잡음비를 나타내었으며 transmit receive head coil을 사용한 두 영역 측정방법과 NEMA는 10% 내외의 상대 표준 편차를 가짐으로써 균질한 값을 보였다. 하지만 다중 채널 코일과 병렬 영상 기법을 적용한 두 영역 측정방법의 경우 20% 이상의 상대 표준 편차를 보여 각 실험마다 신호대 잡음비의 큰 차이를 나타내었고 NEMA와 transmit receive head coil을 사용한 두 영역 측정방법에 비해 신호대 잡음비를 측정한 각각의 영역에서 차이를 나타내었다. T2 강조영상의 경우 transmit receive head coil을 사용한 두 영역 측정방법, AAPM, NEMA, Philips 모두 10% 내외의 상대 표준 편차를 가져 균일한 SNR을 나타내었지만 다중채널코일과 병렬영상기법을 적용한 두 영역측정방법의 경우 20% 이상의 상대 표준 편차를 보여 신호대 잡음비의 차이를 나타내었다. 결 론 : 다중 채널 코일과 병렬 영상 기법 적용 시 잡음의 공간적, 통계적 분포에 영향을 미치기 때문에 두 영역 측정방법으로 산출한 신호대 잡음비는 정확성이 감소하게 된다. 따라서 다중 채널 코일과 병렬 영상 기법을 적용한 영상에서 좀 더 정확한 신호대 잡음비를 산출하기 위해 AAPM, NEMA, Philips에서 제안되는 방법을 이용해야 한다.
