Rapid full-scale expansion joint monitoring using wireless hybrid sensor

장신애,Sushil Dahal,Jingcheng Li 국제구조공학회 2013 Smart Structures and Systems, An International Jou Vol.12 No.4

Condition assessment and monitoring of bridges is critical for safe passenger travel, public transportation, and efficient freight. In monitoring, displacement measurement capability is important to keep track of performance of bridge, in part or as whole. One of the most important parts of a bridge is the expansion joint, which accommodates continuous cyclic thermal expansion of the whole bridge. Though expansion joint is critical for bridge performance, its inspection and monitoring has not been considered significantly because the monitoring requires long-term data using cost intensive equipment. Recently, a wireless smart sensor network (WSSN) has drawn significant attention for transportation infrastructure monitoring because of its merits in low cost, easy installation, and versatile on-board computation capability. In this paper, a rapid wireless displacement monitoring system, wireless hybrid sensor (WHS), has been developed to monitor displacement of expansion joints of bridges. The WHS has been calibrated for both static and dynamic displacement measurement in laboratory environment, and deployed on an in-service highway bridge to demonstrate rapid expansion joint monitoring. The test-bed is a continuous steel girder bridge, the Founders Bridge, in East Hartford, Connecticut. Using the WHS system, the static and dynamic displacement of the expansion joint has been measured. The short-term displacement trend in terms of temperature is calculated. With the WHS system, approximately 6% of the time has been spent for installation, and 94% of time for the measurement showing strong potential of the developed system for rapid displacement monitoring.

市販 綿內衣材料의 實用特性에 關한 硏究

장신애 全州大學校 1981 論文集 Vol.10 No.-

The some properties of commercial cotton-knitted underwears through thread count, thickness, porosity, specific volume, air permeability, thermal transmission, stiffness and elastic recovery were analysed. The materials used were plain, rib and interlock stitch as structure of knit-weave, and 38's, 45's, 60's and 100's as count of yarn number. Air permeability and thermal transmission is higher in plain than interlock stitch of same number of yarn count. The warmth retentively of the knitted fabrics is proportional to thickness, porosity, specific volume, thermal insulation (clo), while it is inversely proportional to air permeability and thermal transmission. Stiffness is lower in course direction than wale direction, in plain stitch of high number of yarn count. Elastic recovery is better in course direction than wale direction and in interlock stitch of lower number of yarn count.

Purpose The purpose of this study was to verify the structural relationship between empowering leadership, job crafting, and job enthusiasm of flight attendants. In addition, we believed that flight attendant personality would moderate the relationship between job crafting and job passion, and wanted to check whether it varied depending on personality factors. Methods Data were collected using an online questionnaire (Naver Questionnaire) targeting 258 domestic airline flight attendants, and the hypothesis was tested using structural equation modeling. Results This study verified the structural relationship between empowering leadership, job crafting, and job enthusiasm of flight attendants. As a result, empowering leadership was found to have a positive effect on job crafting and job enthusiasm, and job crafting was found to have a positive effect on job enthusiasm. Job crafting was found to play a mediating role in the relationship between empowering leadership and job enthusiasm. And in the relationship between job crafting and job enthusiasm, the neuroticism of the 5 personality factors was found to have a moderating effect. Conclusion Personality factors of flight attendants play an important role in the aviation field, and through customized education such as multicultural education and foreign language education, flight attendants' capabilities can be strengthened and talent that matches the organizational culture and goals can be discovered and fostered. Therefore, it is necessary to develop and operate a training program that takes into account the personal and work characteristics of flight attendants.

솜의 保溫特性分析

張信愛,姜蕙遠,金聖連 한국의류학회 1977 한국의류학회지 Vol.1 No.1

The warmth retentivity of natural and syntheic waddings as bedding stuff, and further, the machanism of heat transmission through conduction, radiation and convection were analysed. The materials used were cotton, silk, and wool as natural waddings, and polyamide, polyester, regular acrylic, conjugate acrylic, regular polypropylene and conjugate polypropylene as synthetic waddings. The results of this study are as follow: 1. The warmth retentivity is highest in silk. Following silk in descending order is cotton, conjugate acrylic, polyester, regular acrylic, wool, polyamide, conjugate polypropylene and regular polypropylene. There is not any significant relationship between warmth retentivity and the conductivity of the fibers. 2. Transmission by radiation through the fiber waddings is highest in conjugate polypropylene. Following conjugate polypropylene in descending order is regular polypropylene, polyester, polyamide, conjugate acrylic, regular acrylic, wool, cotton, and silk. This is seen to be in nearly reversed order to the abovementioned order of warmth retentivity. In this respect, warmth retentivity with loose fibreous material as in the case of bedding stuff is primarily affected by the interceptive function of the fibers in heat radiation. 3. Warmth retentivity becomes lower with increasing air content of the waddings. This is because heat transmission by radiation incrases as air content increases. The air content increase is due to the fact that the air is unable to intercept heat radiation. In addition, heat transmission accelates in proportion to the increase in convection as the air gap enlarges.

장신애,윤지은,박정규,Jang, Sin-Ae,Yun, Ji-Eun,Park, Chung-Gyoo 한국응용곤충학회 2009 한국응용곤충학회지 Vol.48 No.2

구더기 치료에 널리 이용되고 있는 무균 구리금파리 [Phaenicia (=Lucilia) sericata (Meigen)]를 보다 손쉽게 사육하기 위한 배지를 선발하고, 알과 유충의 저장조건을 실험하였다. 시판되고 있는 8가지의 미생물 배양용 선택배지에서 실험한 결과, 알의 부화율은 배지 간에 차이가 없었고, 유충의 생존율은 1, 2차 실험결과 blood agar(BA), sabouraud dextrose agar 및 brucella blood agar 배지에서 가장 높았다. BA 및 chocolate agar 배지에서 양의 혈액 함량을 20${\sim}$40%로 높일수록 유충의 생육이 좋았다. 알은 부화율의 저하 없이 $8^{\circ}C$에서는 12일까지 저장할 수 있었고, 3령 초기 유충은 생존율의 저하 없이 $6^{\circ}C$에서 15일까지 저장할 수 있었다. Rearing media were selected for the production of sterile larvae of greenbottle blowfly, Phaenicia (=Lucilia) sericata (Meigen) which is widely used in maggot therapy. Eight media available in the market were used in this study. Egg hatchability was not different among the media. Survivorship of the larvae was higher in blood agar (BA), sabouraud dextrose agar, and brucella blood agar than the others. A higher content (20${\sim}$40%) of sheep blood in BA and chocolate agar increased the survivorship of larvae. The eggs and the early 3rd larvae could be stored for 12 days at $8^{\circ}C$ and for 15 days at $6^{\circ}C$ without decrease in hatchability and larval survivorship, respectively.

이미지 압축을 위한 새로운 기법 중의 하나가 웨이블릿 변환이다. 웨이블릿 변환된 이미지는 이미지 전체의 중요 정보가 한쪽으로 치우치는 경향을 보인다. 그러므로 웨이블릿 이미지를 순차적으로 네트웍상에 전송한다면 중요 정보가 포함된 패킷에 손실이 발생할 경우 이미지의 품질에 치명적인 영향을 미친다. 본 논문에서는 전송된 웨이블릿 이미지의 품질을 보장하기 위한 새로운 패킷타이징 기법을 제안한다. 즉, 주파수 부대역(frequency subband)을 여러 개의 블록으로 나누고, 이 블록들을 서로 다른 패킷에 삽입하여 패킷의 중요도를 분산하는 것이다. 또한 주파수대역이 가장 낮은 부대역 정보를 중복하여 전송함으로써 이미지 전체의 품질을 보장한다. 제안된 기법의 성능을 평가하기 위해 객관적인 성능평가 단위인 PSNR과 주관적인 이미지 분석을 수행하였다. 실험결과 제안된 기법의 성능이 순차적인 블록 패킷 기법에 비하여 PSNR에서 1~4 dB 높았으며, 이미지의 선명도도 높음을 알 수 있었다.

장신애(Shin-Ae Jang),최태욱(Tae-Uk Choi),정기동(Ki-Dong Chung) 한국정보과학회 2002 한국정보과학회 학술발표논문집 Vol.29 No.1A

인터넷 수요의 증대에 따라 오디오나 비디오 같은 실시간 전송을 요구하는 멀티미디어 데이터 응용들도 증가하게 되었다. 이런, 멀티미디어 데이터들의 전송은 패킷 손실과 지연을 최소화 하고, 대역폭 상태에 대해 TCP보다 순화된 전송률 조절이 가능한 혼잡제어 기법이 필요하다. Receiver-based 혼잡 제어방식은 network traffic의 변화에 신속히 대응할 수 있으며, 이 방식은 Sender-based 방식에 비해 멀티캐스팅 환경에 적당하다는 장점도 가진다. 본 논문에서는 인터넷 상에서 audio/video 데이터들의 종 단간 Layered Quality Adaptation 을 제공하는 receiver-based 혼잡 제어 기법을 소개한다. 이를 통해 사용자들은 보다 좋은 QoS를 제공받을 수 있다.

장신애 ( Sin Ae Jang ),최성이 ( Sung Yi Choi ) 한국무용과학회 2012 한국무용과학회지 Vol.27 No.-

본 연구는 RAD (Royal Academy of Dance)발레 프로그램을 통한 자세교정에 관하여 연구하기 위하여, 경기도 오산시에 소재한 D중학교 여학생 30명을 대상으로 주 3회 50분씩 8주간 프로그램 참여 전 후 어깨 기울기, 골반 기울기, 다리굴곡, 경추 기울기, 상체 기울기, 골반전후 기울기를 PAPS 자세평가 도우미 3.0을 이용해 측정하였다. 측정결과는 다음과 같다. 첫째, 어깨 기울기에서 정상 또는 경미로 7명이 호전되었다. 둘째, 골반 기울기는 경미에서 정상으로 2명 호전되었다. 셋째, 다리굴곡은 심각에서 경미로 1명 호전되었다. 넷째, 경추 기울기에서는 경미에서 정상으로 3명 호전되었으나 정상에서 경미로 1명 악화되었다. 다섯째, 상체 기울기는 정상과 경미로 7명 호전되었다. 여섯째, 골반전후 기울기는 심각에서 경미로 1명 호전되었으나, 정상에서 경미로 1명 악화 되었다. 마지막으로 개인별 검사결과의 합계에서는 자세가 호전된 실험군이 21명, 변화가 없는 실험군이 8명, 자세가 악화된 실험군이 1명으로 나타났다. The posture before and after the RAD ballet program participation 3 times a week by 50 minutes for 8 weeks was measured based on 30 female students of D middle school in Osan city of Gyeonggi Province by using PAPS (Physical Activity Promotion System) 3.0 in order to examine the effects of the ballet movement program participation on the positional distortion of middle school girls. As results of analysis of the collected materials in this study, the following conclusions were drawn. First, 7 students were improved in shoulder slope with normal condition or slight condition. Second, 2 students were improved in pelvic tilting from slight condition into normal condition. Third, 1 student was improved in leg flexion from the serious condition into slight condition. Fourth, 3 students were improved in cervical slope from slight condition into normal condition but 1 student was deteriorated from normal condition into slight condition. Fifth, 7 students were improved in upper body slope with normal condition and slight condition. Sixth, 1 students was improved in front-back pelvic tilting from the serious condition into slight condition but 1 student was deteriorated from normal condition into slight condition. Lastly, in the sum of the individual test results, the member of experimental group which the posture was improved was 21 students, the unchanged experimental group was 8 students, and deteriorated experimental group was 1 student. Therefore, the ballet movement program was shown that helps creating the correct posture of the upper body in short time, and the program participation for longer time is necessary for creating the correct posture of the lower body, and it is considered that if the program participants are limited with 10~15 students in one class, then both students and teachers will improve the concentration and it will be the efficient progress. If this posture assessment is conducted nationally and politically in many elementary, middle and high school periodically every year but not only for the research or experiments, then it will be the good opportunity for the adolescents to be grown up as the healthy adults. It is considered that it will be able to be the basic foothold which can develop the ballet movement program as well as many good exercise programs for the posture correction of the adolescents in a growth phase.
