본 논문에서는 이동로봇에 적외선 카메라 및 LPG센서, CO센서, 온도센서를 장착한 로봇을 화재지역 및 극한 상황에 투입하여 적외선카메라를 이용한 현장상태 파악과 LPG가스 농도, 일산화탄소 농도 및 온도 등 현장상태를 파악하여 현장을 모니터링 할 수 있는 이동로봇을 구현한 것에 대해 설명하고자 한다. 또한 카메라로 볼 수 없는 사각지대의 장애물을 초음파센서가 감지하여 그 순간의 엔코더 값을 저장한 뒤 모니터상에 장애물의 위치를 나타내어 이동로봇의 현장상황을 모니터링 하는데 도움이 되도록 장애물을 인지할 수 있는 맵핑을 구현한 것에 대해 설명하고자 한다.

Objectives: The purpose of the study is to investigate self-efficacy, self-image, and image as a dental hygienist of the dental hygiene student. Methods: A self-reported questionnaire was completed by 479 dental hygiene students in Daegu and Gyeongnam from November 5 to 25, 2014. The questionnaire consisted of self-efficacy(18 items), self-image(23 items), and image as a dental hygienist(36 items) by Likert 5 points scale. Data were analyzed by t test, ANOVA, regression analysis, and post hoc Tukey test using SPSS 20.0 program. Results: The self-efficacy of the first, second, and third grade was 2.72, 2.71, and 2.60, respectively(p<0.002). Those living with family tended to have higher mark than those living without family(p<0.001). The influence of self-efficacy on self image and image as a dental hygienist was positively correlated(p<0.001). Conclusions: The right self-image and self-efficacy of the dental hygiene students can be a powerful influence on the image as a dental hygienist. It is necessary to develop and implement the ethics education for the dental hygiene students.

This paper introduces a moving robot distributed control system which has possible to minimize hardware system and increased efficiency. Also it gives ill when transmitting the data. So system can add sensor and reduce module flexibly. so applied system is expected to reduce host computer task through date error detection in hardware level.

TCMS(Train Control & Management System) control, monitor and test the main on-board equipments including propulsion/brake unit by the serial transmission line. TCMS reduces interface circuits and number of train lines by the software logic and utilizing serial communication method. This paper describes the method of powering and braking control by TCMS software logic, and the software logic is verified by running test at Seoul Subway Line# 6. By running test result, we can see TCMS successfully control Powering/Braking of train.

제초제 저항성 논잡초 발생면적은 농촌진흥청 국립농업과학원과 전국 8개 도 농업기술원과 공동으로 조사하였다. 8개 도 농업기술원에서 2011년 8월에 논토양을 채취하여 피라조설퓨론에틸 피리미노박메틸입제를 30kg ha-1 처리하여 설포닐우레아(SU)계 제초제 저항성 논잡초의 발생면적을 추산하였다. 전국 벼 재배면적(유기 및 친환경농업 벼 재배면적 제외)의 20.9%인 167,081ha에서 SU계 저항성 논잡초가 발생되고 있음을 확인하였다. 2008년과 대비하여 본 결과 60,130ha가 늘어났다. 발생비율을 보면, 충청남도가 논 면적의 47.6%로 제일 많이 발생되었고, 그 다음으로는 전라남도로 36.9%, 충청북도 25.7%, 강원도 20.3%, 경기도 13.0% 순이었다. 제초제 저항성 논잡초 중 발생면적이 가장 넓은 초종은 물달개비로서 65,313ha로 전체 39.1%를 차지하였으며, 그 다음으로 올챙이고랭이, 알방동사니 순이었다. 이들 3초종은 전국적으로 고르게 발생하여 제일 문제되는 잡초들이다. 그리고 미국외풀 13,964ha(8.4%), 강피 5.1%이었다. National Academy of Agricultural Science and eight province Agricultural Research & Extension Services investigated the occurring area of herbicide resistant weeds in paddy field of Korea. In order to estimate the occurring areas of herbicide resistant weeds, we collected paddy soils on August, 2011 and treated 30kg $ha^{-1}$ of pyrazosulfuron-ethyl+pyriminobac-methyl GR. 167,081ha, approximately 20.9% of cultivated area excluding organic and eco-friendly cultivated area, was estimated to be infested by SU-herbicide resistant paddy field weeds. It was increased by 60,130ha compared with investigation of 2008. It was occurred at Chungchungnam-do by 47.6%, followed by 36.9% at Jeonranam-do, 25.7% at Chungchungbuk-do, 20.5% at Gangwon do, and 13.0% at Gyeonggi-do, respectively. Monochoria vaginalis showed the highest with 65,313ha, 39.1% followed by Scirpus juncoides, and Cyperus difformis, respectively. These three species were evenly distributed and the most problematic weeds in the country. Lindernia dubia occurred at 13,964ha (8.4%) and Echinochloa oryzicola was 5.1%, respectively.

TCMS(Train Control & Management System) is the management system of train information which intensively control, monitor and test the main on-board equipments including propulsion/brake unit by the serial transmission line. TCMS reduces interface circuits and number of train lines by the software logic and utilizing serial communication method. This paper describes the method of powering and braking control by TCMS software logic, in comparison with the powering / braking control by conventional relay logic / hard wire circuits, and the software logic was verified by simulation test with TCMS simulator.
