KoreaMed MeSH 반자동 색인 시스템이 논문 제목, 초록 그리고 저자키워드를 활용하여 부여한 KoreaMed MeSH 체크태그와 NLM의 MeSH 색인전문가가 부여한 MEDLINE MeSH 체크태그와의 일치여부를 비교 분석하였다. KoreaMed 학술지중에서 MEDLINE에 등재된 15종 학술지의 2012년 마지막 호에 실린 논문 236편을 표본으로 선정하여 일치도를 분석한 결과 MEDLINE MeSH 체크태그와 KoreaMed MeSH 체크태그와의 일치율은 30.24%였다. 그러나 KoreaMed MeSH 체크태그를 기준으로 했을 경우 MEDLINE MeSH 체크태그와의 일치율은 84.24%에 달했다. 일치율은 종별이 가장 높았고, 동물명, 성별, 연령그룹순이었다. 연령그룹에 대하여 초록내 패턴을 발견하여 반자동색인 필터로 적용한다면 일치율을 높일 수 있다. 궁극적으로는 연구의 핵심적인 연구대상이나 재료를 특정적이고 구체적인 단어 혹은 MeSH로 표현하는 초록 작성 기술이 요청된다.

The purpose of this study was to investigate the sensibility image of necktie according to width and color combination of checked pattern. The experimental materials developed for this study were a set of stimulus and response scales. The stimuli were 18 color pictures, in which the width(small: 0.2cm, medium: 1cm, large: 2cm), tone combination(similar, contrast), and hue combination(WR: white+red, WB: white+blue, WG: white+gray) were manipulated. The 7-point scale was used for evaluation of sensibility image. The subjects of this research were 216 female college students living in Gyeongnam. The investigation was carried out at September 2009. The data were analyzed by using SPSS program. Analysis methods were ANOVA and Duncan-test. The results of this study were as follows.; The analyses of sensibility for necktie according to width and color combination of checked pattern revealed that the concerned factors are five characteristic dimensions of attractiveness, youth, appeal, elegance, and warmness. Width showed an independent effect on appeal. Tone combination showed an independent effect on attractiveness, appeal, elegance, and warmness. Interaction effects of width and tone combination on attractiveness were found. Hue combination showed an independent effect on all dimensions. In addition, significant interaction effects of width and hue combination on attractiveness, youth, appeal, and elegance were found. Significant interaction effects of tone combination and hue combination on attractiveness, youth, and appeal were found.

This study investigates the image of casual shirts according to color combination, tone, and interval of checked pattern in tone-in-tone coloration. The experimental materials developed for this study were a set of stimulus and response scales. The stimuli were 24 color pictures, in which color combination (RY: Red+Yellow, BP: Blue+Purple), tone (light, dull, dark), and interval (0.5cm, 1.5cm, 3.5cm, and 5.5cm) were manipulated. The 7-point scale was used for evaluation of image. Data were obtained from 240 female college students living in Seoul, Gwangju, Jinju, and Changwon in April 2010. For data analysis, ANOVA and Duncan-test were used by using SPSS program. The results of this study are as follows. Image according to color combination, tone, and interval of checked pattern consisted of five dimensions of attractiveness, youth- activity, appeal, modesty, and freshness. The cover combination showed an independent effect on freshness. Tone showed an independent effect on attractiveness, youth-activity, appeal, and modesty. Interval showed an independent effect on appeal, modesty, and freshness. Interaction effects of color combination and tone on youth-activity and appeal were found. In addition, interaction effects of tone and interval on attractiveness, youth-activity, and freshness were also found.

About 58% of fires are electric fires. In this study, we analyzed the factors of fire caused by electricity and studied the system that can prevent fire in advance. In order to prevent disasters, basically, various electrical IoT sensors are needed to detect fire signs. Each of these sensors continuously receives a lot of situation information and sends it to the main system. The collected big data continuously checks whether the disaster is over the threshold that can cause disaster through pattern analysis, and can check whether there is any problem by comparing the data. In the event of a threshold, alarms are signaled and problems are reported. This prevents fire by preventing electrical problems such as overcurrent and leakage current.

본 연구에서는 백라이트 유닛의 검사를 위한 머신비전 시스템을 구축한다. 시스템은 크게 하드웨어와 소프트웨어로 나눌 수 있고 하드웨어는 조명부, 영상획득부, 로봇 암 제어부로 분류된다. 조명부는 36W FPL램프로 구성되었고 조명부의 상판에 아크릴판을 거치대로 이용하여 백라이트 유닛을 거치한다. 로봇 암 제어부는 2축 로봇 암을 제어하여 로봇 암의 센서부착 지지대에 부착된 CCD 센서를 이동시킨다. 이와 동시에 영상획득부에서는 이미지를 획득하여 PC로 전송한다. 소프트웨어의 화상처리 검사 알고리즘은 일정 패턴이 있는 도광판에 대한 검사 알고리즘과 일정패턴이 없근 백라이트 유닛에 대한 검사 알고리즘으로 분리된다. 일정 패턴이 인쇄되어 있는 패널에 대한 검사 알고리즘은 모폴로지 연산을 이용하는 템플릿 체크방법과 블록 매칭 방법이 사용되었고 일정패턴이 없는 유닛에 대한 검사는 개선된 Otsu 방법을 이용하여 얼룩이나 흐릿한 결함에 대한 결함을 검출하였다. 실험결과 불균일한 결함과 밝기가 일정하지 않은 결함일지라고 90% 이상의 검출율로 뛰어난 성능을 입증하였다.

국내 공작기계 시장은 일본 화낙사 컨트롤러를 사용하는 비중이 80[%] 전후이며 그 비중이 높다고 할 수 있다. 최근, 기계가공 분야에서도 IoT(Internet of Thins) 환경을 도입하여 공장의 스마트화가 이루어지고 있다. 대부분의 공작기계를 소유하고 있는 산업현장에선 공작기계에 관한 모니터링 시스템에 대한 필요성을 인식하고 있으며, 공작기계의 가동률 체크 뿐만 아니라 가공패턴 및 가공시간 등을 견적서 자료로 활용하려하고 하고 있다. 이러한 요구조건을 충족시키기 위하여 가공기계 분야에도 ERP(Enterprise Resource Planning)시스템을 도입하여 생산 공정관리의 기초 데이터로 활용하고 있다. 이러한 생산 현장을 감안하여 공작기계에 대한 공정 모니터링 기능 및 스마트화가 무엇보 다 중요하다고 할 수 있다. 본 논문에서는 화낙(fanuc)에서 제공하는 FOCAS 라이브러리를 활용하여 공작기계 가동률에 대한 체크가 가능하도록 Wi-Fi 기반의 데이터 전송 모듈을 개발하여 공작기계 모니터링에 필요한 소형의 통신모듈을 제시하고자 한다.

In this paper, a novel drowsiness detection algorithm using eye-blink pattern is proposed. The proposed drowsiness detection model using finite automata makes it easy to detect eye-blink, drowsiness and sleep by checking the number of input symbols standing for closed eye state only. Also it increases the accuracy by taking vertical projection histogram after locating the eye region using the feature of horizontal projection histogram, and minimizes the external effects such as eyebrows or black-framed glasses. Experimental results in eye-blinks detection using the JZU eye-blink database show that our approach achieves more than 93% precision and high performance.

The pattern locking technique applied to smart phones is a locking technique that many people use conveniently. However, the safety of pattern locking techniques is very low compared with other techniques. The pattern locking technique is vulnerable to a shoulder surfing attack, which is based on the user's input and can be interpreted by looking at the movement of the shoulder, and the smudge attack is also vulnerable due to fingerprint drag marks remaining on the mobile phone pad. Therefore, in this paper, we want to add a new security method to check the pressed time by using a thread in the pattern locking scheme to secure the vulnerability. It is divided into short, middle, and long click according to the pressing time at each point. When dragging using the technique, security performance enhances $3^n$ tiems. Therefore, even if dragging in the same 'ㄱ' manner, it becomes a completely different pattern depending on the pressing time at each point.

The purpose of this study is to analyze check pattern of nail art from 2011 to 2013. The results of this study are as follows; 1) Check pattern of nail art is total 257 patterns, and there are 84 argyle, 29 tartan, 24 harlequin, 24 over, 23 window-pane, 15 stitcheds, 13 hound tooth, 10 block, 10 madras, 8 gingham, 8 gradation, 7 shepherd, and 2 tattersall check patterns. Through this result, in nail art, the relatively simple patterns such as a vertical pattern, a horizontal pattern, and cross or overlap diagonal line are used more than elaborate and complex check patterns of a fibrous tissue from a weaving process. 2) In check pattern of nail art, N-affiliated color and R-affiliated color are remarkably well-used, because of the effects of argyle, tartan, window-pane, harlequin, stitched, over, and hound tooth check patterns used the most during the past three years. Especially, most tartan, harlequin, over, and hound tooth check patterns use their own special colors such as R-affiliated colors and N-affiliated colors as it is, and argyle, window-pane, stitched, and over check patterns use well by arranging N-affiliated colors and R-affiliated colors. 3) The most used expressive technique is hand painting to express check pattern in nail art, because new products related to UV gel are well launched. These materials can draw fine line that is hard to express by existing polish easily and simply, and not only have set quickly hard, so procedure time is very short, so it is compatible to draw check pattern personally, but also it is well covered, so check pattern is more clearly expressed.
