It is necessary to induce for using mass transit instead of passenger car, which is high occupied roadway. It is necessary to develop the automated enforcement system to do manage such things. There are lots of problems to enforce the exclusive roadway. One of the biggest problem is the difficulty of vehicle classification. In this paper, morphological vehicle classification algorithm is proposed. Vehicle object is separated from background using frame difference, then the proposed unique weighted skeleton feature is extracted. The experiments show that the vehicle identification results produced by weighted skeleton feature seem to be good quality.

최근 홈 네트워크라는 용어가 대중매체에 등장하고, 해외 선진국은 물론 세계 여러 나라들은 수년 동안 이러한 분야에 중점을 두고 연구 개발에 집중하고 있다. 현재 우리나라에서도 홈 네트워크에 관한 다양한 연구 개발이 이루어지고 있다. 특히 홈은 개인이 사용할 수 도 있지만, 다수의 가족이란 구성원이 존재하는 공간이다. 따라서 가정환경에 맞추어 능동적인 홈 네트워크 시스템이 작동하려면 다양한 상황과 각각의 상황에 맞는 서비스를 제공 받을 수 있어야 한다. 이를 위해 상황 인식 기반 홈 네트워크 개발 연구가 활발히 진행 중이다. 본 논문에서는 효율적인 홈 네트워크 구성을 위한 상황 인식과 컴퓨팅에 관해 고찰하고 이를 통해 보다 개선된 상황 인식 시스템을 설계한다.

Korean seafarers have played a key role throughout the country's history and economic development. They have been a major source of foreign remittance into the nation as well as a pivotal sector in emergency logistics during war times. However, the current number of Korean seafarers in decreasing due to low job attractiveness and retention rate onboard. This is a major problem for the national and international shipping industry as youth seem not to be interested in working onboard for long periods of time. The purpose of this study is to 1) determine what the public opinion about seafarers in Korea is and 2) find out what factors mostly stand out in the public opinion about seafarers profession. The paper suggests that three main types of opinion groups emerged. The first type is labeled as 'high risk, high workload and high stress' as respondents recognized a high possibility of accident onboard and, at the same time, acknowledged that seafarers can be fatigued and stressed. The second type was named as 'Dangerous, Dirty, Difficult', as seafarers' image was mainly associated to fishing vessels and not to merchant and passenger ships. The third type recognized that the social position of the seafarers was low due to 'low social recognition'. The study suggests that all three types have a negative image of seafarers' job. Based on the results of this study, it is necessary to establish various policies and marketing tools to improve the negative job image linked to seafarers by the public opinion. If the public image of seafarers can be improved and attractiveness rose, it is expected a higher number of seafarers will pursue and keep a career at sea.

To achieve the goal of this study, prior studies of frame analysis were reviewed, and tweets of presidential archives and records before and after the impeachment were collected. This study conducted an analysis of Twitter and news extracted from Twitter using user frames and determined the differences between each frame over time. Afterward, five frames were set up to be used for the research through prior research and Twitter network analysis; changes in frames over time were examined by analyzing Twitter and news extracted from Twitter. Through such frame analysis, changes in the frame of presidential archives and records before and after the impeachment were examined, changes in public perception of presidential archives and records were identified, and areas of interest were determined. This study is significant as it identified changes in the public perception of presidential archives and records as well as in the areas of interest for the general public.

This study investigated perception of first-year college students who recently experienced technology education in their secondary education for describing contemporary technology classrooms. To accomplish this goal, survey and in-depth interview on their technology classrooms were employed. Participants in this study were 427 first-year college students who began their college life in 2013 and consisted of 224 students enrolled in 10 departments of educational major and 203 students who enrolled in 9 departments of other colleges. The instrument of this study consisted of preference toward technology classrooms and teachers, experience in the secondary technology classrooms, perception toward technology teachers, and suggestions for technology classrooms with five point Likert scales and open-ended questionnaires. And individual in-depth interviews with 22 volunteers who answered the instrument and consented the interview process were conducted. Based on the collected data, statistical and theme analyses were performed and the key findings were as follows. First-year students' experiences for technology classrooms were described with the theme of 'learning contents or activities'(54.4%). And the negative perception toward technology classrooms(29.1%) was larger than he positive perception(16.5%). The perception toward technology classrooms was also presented with two themes of teaching methods and subject interest. The perception toward technology teachers presented a medium level preference with several themes of teachers' teaching methods, teachers' personality, and subject interest. Lecture style method(60.48%) was largely used in the participants' technology classrooms and problem solving or collaborative methods was not frequent(19.31%). The participants indicated a need for improving teaching methods in technology education and suggested sufficient administration and curriculum supports and transitions of the learning contents. Further studies investigating the diverse public's perception toward technology and technology classrooms could be recommended.

최근, 블루투스 통신이 가능한 스마트폰이 널리 사용되면서, 블루투스 기반의 비콘이 마케팅이나 실내위치기반서비스 등에서 많이 이용되고 있다. 하지만, 비콘의 특성상 정확한 측위가 어려워 응용 분야가 다소 제한적이다. 이 논문에서는 승객의 비콘을 이용하여 대중교통 승하차를 비 접촉식으로 인식하고 과금으로 연결하는 시스템을 제안한다. 이 논문에서는 기존 RSSI를 이용하는 비콘 기반 측위 방법이 신호간섭에 따라 신뢰성이 떨어지는 문제를 해결하기 위한 새로운 방법을 제안한다.
