This study is to develop a web-based career guidance system to be a help making a decision on one's occupation, which is important for a person's life. As career development education for higher grades of elementary school aims at providing basic knowledge necessary for career choice and forming a basic attitude toward occupation and values, it is desirable to carry out the guidance of a variety of occupations on the basis of personal interest and aptitude of individual students. Previously, however, most studies have remained at the level where simply test results are notified. Therefore, the study administered a career development test fit for higher grades of elementary school who are at the stage of potential career choice and developed a web-based career guidance system in which suitable occupation types are advised of based on the results. Beyond notifying test results, the developed career guidance system presents 3 excellent intelligences, rather than converting test results into scores. Thus, it is expected that the system will help students understand their areas of excellent intelligence, efficiently study related occupation types and duties, and learn to have awareness and make a better decision in relation to their career.

Standard industry and occupation code are usually assigned manually in Korean census. The manual coding is very labor intensive and expensive task. Furthermore, inconsistent coding is resulted from the ability of human experts and their working environments. This paper proposes an automatic code classification system which converts natural language responses on survey questionnaires into corresponding numeric codes by using manually constructed rule base and example-based machine learning. The system was trained with 400,000 records of which standard codes was assigned. It was evaluated with 10-fold cross validation and was tested with three code sets: population occupation set, industry set, and industry survey set. The proposed system showed 76.63%, 82.24 and 99.68% accuracy for each code set.

지식, 기술, 정보가 경쟁력의 원천이 되는 산업 발전의 변화추세에 따라 세계 각국은 일-교육$\cdot$훈련-자격의 긴밀한 연계체제인 국가직업능력표준을 동해 국가 인적자원 개발 시스템을 개선해 나아가고 있다. 우리나라에서도 노$\cdot$사$\cdot$정 합의에 의해 2002년부터 전 산업분야에 적용될 국가직업능력표준이 개발되고 있다. 이렇게 개발된 국가직업능력표준을 이용하여 우리나라 기능대학/전문대학의 컴퓨터 응용기계설계과에서 활용할 수 있는 교육과정과 교재개발방안을 제시한다.

As the amount of web contents in the Internet increases, it becomes hard to find out statistics that users want. In this paper we propose an analysis system based on the statistics of words, which can be used to prospect trends in a specific area. We applied this system to job recruiting site and we can find out trend and statistics about what part of technology is needed in job market and the result of this paper can be used for an application such as restructuring curriculum of a department in universities. It can also be used to predict trend in other areas.

유비쿼터스 시대를 향하여 나아가는 현대 사회에서 사람들을 위한 추천시스템은 필수 불가결한 요소 중의 하나이다. 추천 시스템 중에서 사용자의 성별, 나이, 직업 등의 인구 통계적 요소를 고려한 시스템이 주를 이루고 있지만 이러한 시스템에는 어느 정도의 한계가 있다. 추천에 있어서 사용자의 기분, 날씨, 온도 등 주변 환경의 상황이 반영되지 않고 있고 학습을 위한 데이터에 대한 신뢰도 또한 문제가 된다. 이러한 문제점을 해결하기 위해 본 논문에서는 상황정보(Context Information)와 공간 데이터 마이닝(Spatial Data Mining) 기법을 이용한 향상된 추천 시스템을 제안한다. 제안하는 시스템에서는 보다 정확한 추천을 위해 첫째, 날씨, 온도, 사용자의 기분 등의 상황정보를 고려하였다. 그리고 사용자의 유사도 측정을 통해 학습 데이터의 신뢰도를 향상시켰으며, 셋째, 의사결정 트리(Decision Tree) 기법을 이용하여 추천의 정확도를 높였다. 실험을 통하여 측정한 결과 제안하는 추천시스템이 기존의 인구 통계적 요소만을 고려한 시스템이나 의사결정 트리만을 이용한 시스템보다 향상된 성능을 보였다.

본 시스템은 컴퓨터를 이용한 검사의 효율성과 편리성의 장점을 활용하여 웹기반의 시스템 환경에서 학생들에게 직무에 필요한 기초능력을 영역별 세부항목으로 분류, 단계별로 제시하고, 각 영역별 문제를 스스로 학습함으로써 자신의 기초능력을 백분 발휘할 수 있도록 도와주며, 또한 검사 후 결과에서 각 영역을 자세히 분석해줌으로써 학생 스스로 자신의 부족한 능력을 진단하고 재학습 할 수 있도록 피드백을 제공한다.

본 논문에서는 웹상에서 학습자의 학습능력을 진단하기 위하여 각 단계별로 질문을 제시하고 질문의 응답여부에 따라 자신의 학습 능력을 평가받고 향후 자신의 능력을 좀 더 향상시킬 수 있는 지침을 제공하는 학습능력 진단시스템을 개발하였다. 본 시스템에서는 소프트웨어 프로세스를 향상시키기 위해 사용되고 있는 능력성숙 모델(CMM)을 기반으로 질문 리스트를 구성하였으며 다양한 학습자의 학습능력을 전단할 수 있도록 학습자의 직업에 따라 별도의 질문 리스트를 준비하였고 질문 리스트와 메시지 및 가산점을 조정한다면 다양한 분야에서도 활용될 수 있을 것이다.

Multimedia isn ow applied to various real world areas. In particular, the focus on multimedia system and CSCW(Computer Supported Cooperative Work) has increased. In spite of this current trend, however, the study of fault tolerance for CSCW has not yet fully progressed. We propose EDR_MSCW. It is a system that is suitable for detecting ad recovering software error based on multimedia computer supported cooperative work as DOORAE by using software techniques. DOORAE is a framwork for supporting development on multimedia applications for computer-based collaborative works. When an error occurs, EDR_MCSCW detects an error by using hooking methods in MS-Windows API(Application Program Interface) function. If an error is found, we present a checkpointing and recovery algorithm which has the removal function of the domino-effect for recovering multimedia and CSCW by using stack.

As a method of providing lifelong educational opportunities to working professionals, some legal provisions allowing for the establishment and management of an entrusted education system linked with college and corporation was duly approved in 1994. According to the recent trend in the military organization, to provide higher educational opportunities to noncommissioned officers and warrant officers with the purpose of inspiring their spirit and improving military capabilities has been much increased. Professional soldiers such as noncommissioned officers and warrant officers have a lot of problems to continue their attendance at school because of regular military maneuvers, constant alert status and long-term outdoor military training. Even more serious problem is that the current curriculums and some departments in college are not concurrent with the present job specifications and the military specialties of the individual soldier as well. The purpose of this paper is, therefore, to introduce a newly revised educational model that provides more viable academic courses and curriculums to military professionals along with a proposal for the establishment and management of long distance educational system within barracks, utilizing the latest information and telecommunication technology.

Purpose: This study aims at developing and implementing Smart Safety Management System based on IoT/ICT Convergence for safety of high-risk groups working at disaster or industrial field. Its functions are as follows. Method: We will develop three devices for keeping the safety of high-risk jobs: Sensor of inactivity, Lora based Refitting technology for communication between high-risk workers, and Lora Gateway for monitoring entire situations. Then we will test three devices in respect of their functions, and propose their applicabilities in the field. Results: The system can send and receive safety tags and danger signals by which sensor technology can detect dangerous state of workers. And its command terminal was developed by low-power wireless communication technology and LoRa Gateway, which can fulfill the lifting functions between safety tags. And, furthermore, the command terminal can monitor dangerous situations of disaster sites in real time and can perform the preemptive rescues. Conclusion: This study proves the functional efficacy of Smart Safety Management System for worker safety in various high-risk occupational groups, and also suggests ways to secure worker safety in disaster area and various high risk industrial sites.
