An issue of globalized and competitive business environment is a transformation of manufacturing strategy for rapidly product development. To copy with these trends, building up a market from various product is becoming conspicuous the core strategy of manufacture. Therefore, it is increasing of necessity for the environment of collaborative product development. As a part of corresponding for these demands, we propose the method that allows easy and rapid integration of legacy resources within the company and between departments. The proposed framework can easily construct a distributed environment for collaborative design between departments in the companies. It was implemented using CO<SUP>TM</SUP> based on DOME (Distributed Object-based Modeling Environment) that is knowledge based engineering solution.

The purpose of this study is to design and implement web-based quality cost management system to measure the performance of quality improvement activities in the business firms. The designed web-based quality cost management system which is also known as

선박의 안전운항을 위해서 설치되어 있는 많은 수의 등대를 관리하기 위해서는 유지비가 과다하게 지출되고 있는 것이 현재의 상황이다. 이러한 이유로 등대를 원격 제어하는 시스템이 실제 운용되고 있지만, 위성 망이나 RF 망을 이용하기 때문에 과다한 통신비용이 발생하고, 단지 측정 데이터만을 전송하므로 실제 등대의 상태를 파악하기 어렵다. 따라서, 본 논문에서는 도서지역까지 확대된 이동 통신기술인 CDMA방식을 이용하여 등대를 양방향으로 원격 제어하고 감시하는 등대 원격 제어 시스템을 구축하여 그 효용성음 확인하였다.

This research was conducted by the request of the Ministry of Education as a part of $quot;The investigation of the priority (of Oceangraphy field) of the long term education loan project$quot;, which is promoted in order to find the ways) to reinforce the Oceanography education. The first Oceanography department in Korea was established in 1968 at Seoul National University. During the last 20 years, 10 Oceanography departments, 5 ocean engineering departments and 1 ocean development department were established at 8 universities and 4 colleges. However, the education facilities and the quality of education were not sufficiently improved. Furthermore, an Oceanography research vessel was not built for those ocean related departments up to now. The authority of the Ministry of Education, which foresaw the fast-changing marine policy of each nation and the rapid technological advances of ocean development, prepared a plan to search a way to reinforce the college level Oceanography education so as to secure the future survival of this nation. Therefore, through this investigation a reinforce plan of Oceanography education in Korea was formalized.

최근 ADCP (Acoustic Doppler Current Profiler) 등 첨단장비를 활용한 유량 및 하상측정, 각종 하천기본계획 수립 시 확보되는 횡단측정 자료, 식생 및 서식처 등 하천환경과 생태자료, 드론 등을 활용한 영상자료 등 방대한 하천 정보가 확보되고 있으며, 다기능보 등 다양한 하천구조물 및 친수구역이 증가하는 등 이전과 비교하여 괄목할만한 수준으로 정보의 양이 증가하고 있다. 이에 따라 다양한 하천정보를 체계적으로 저장, 관리, 공유하기 위하여 표준화 된 데이터 모델의 수립이 필요하다. 하천 정보의 경우 하천 시설물, 하천 단면측량 자료, 하천 시계열 측정 자료 등이 특정 하천을 중심으로 관리되는 반면, 기존 데이터 모델 연구에서는 특정 주제도에 기반하여 하천 정보가 레이어 형식으로 제공되어 상호 연계되지 않아 하천 정보의 효율적 관리측면에서 적합하지 않았다. 또한 신규 정보를 추가 시 기존 데이터 모델의 과다한 수정이 필요하고, 기존의 데이터 모델의 경우 표준화되지 않아 활용성이 매우 낮고, 유역중심으로 구성되어 특정 조건에 해당되는 하천 정보 검색이 어려운 단점이 존재하였다. 본 연구에서는 기존의 주제도 및 레이어 형식으로 구성되어 있던 데이터 모델 형식에서 벗어나 하천흐름선을 기준으로 데이터모델을 구축하는 방안을 제시하였으며, 하천흐름선과 하천 시설물, 단면 측량 자료, 계측 자료를 순차적으로 수용하고, 최근 신규로 생성되고 있는 다차원 하천 정보의 추가 시 기존 데이터 모델의 형식을 수정하지 않고 유연하게 대응할 수 있는 관계형 데이터 모델을 구상하였다. 또한, 하천과 유역의 논리적 저장방안 고려하여 한 개의 하천을 다수의 세그먼트로 구분하여 코드(Reach Code)를 부여하는 방안을 제시하였으며, 구상한 데이터모델을 통하여 국가하천과 지방하천 등 유역의 다양성을 포함하는 한강권역의 섬강유역을 시범하천으로 구축하였다.

BIM is an opportunity to implement construction IT. BIM has brought two changes. One is the change of geometric Information. It is the transition from 2D CAD to 3D model. The other is property changes. Requires conversion from data to information. This is a confergence of geometric information and attribute information, and BIM requires convergence in the construction work process. This study aims to present a method for activating BIM in Project management. The first task after the design is quantity take-off. The QTO is a process of converting the geometric information (Analog) into the attribute information (Digital). This QTO-database is important information that can be based on Project management. Therefore, it is necessary to construct information that is useful from QTO. It is WBS-CBS integrated information. BIM-based QTO refers to linkage between 3D model object and WBS-CBS. Through this study, we show the method of WBS-CBS integrated information based on BIM and show the applicability of BIM through actual case. This study is expected to be a basis for the successful implementation of BIM-based project management.

There has been a growing concern on ontology especially in recent knowledge-based industry and defining a field-customized semantic word network is essential for building it. In this paper, a word network for ontology is established with 785 publications of Korean Society of Rural Planning(KSRP), from 1995 to 2017. Semantic relationships between words in the publications were quantitatively measured with the ‘normalized pointwise mutual information’ based on the information theory. Appearance and co-appearance frequencies of nouns and adjectives in phrases are analyzed based on the assumption that a ‘noun phrase’ represents a single ‘concept’. The word network of KSRP was compared with that of WordNetTM, a world-wide thesaurus network, for the verification. It is proved that the KSRP’s word network, established in this paper, provides words’ semantic relationships based on the common concepts of Korean rural planning research field. With the results, it is expecting that the established word network can present more opportunity for preparation of the fourth industrial revolution to the field of the Korean rural planning.

감성 분석은 글을 통해 작성자의 주관적인 생각이나 느낌을 분석하는 방법으로 효과적인 감성 분석을 위해서는 감성 단어 극성 사전 구축이 필수적이다. 본 논문은 효율적인 한국어 극성 사전 구축을 위해 우리가 개발한 크라우드소싱 기반 게임을 소개한다. 먼저, 크롤러를 이용해 인터넷 커 뮤니티에서 말뭉치들을 수집했고, Twitter 형태소를 이용해 수집한 말뭉치를 형태소별로 분류하고 단어화했다. 이 단어들은 모바일 플랫폼 기반 태깅 게임 형태로 제공되어 게임플레이를 통해 플레 이어들이 자발적으로 단어들의 극성을 선택하고 결과가 데이터 베이스에 축적되도록 게임이 설계 되었다. 현재까지 약 1200여개의 단어들의 극성을 태깅하였으며, 향후 좀 더 많은 감성 단어 데이 터들을 축적함으로써 특히 게임 도메인에서 한국어 감성 분석 연구에 기여할 것으로 기대한다.

Quality control of concrete during its curing process is crucial when it comes to reaching the ideal strength. This paper presents the basic study of optimizing concrete curing process by using Arduino platform based on the maturity method. The research has suggested a quality control of curing process by visualizing the curing temperature and its strength from web. The maturity method was coded into the web which allows managers to monitor regardless their locations.
