This study analyzed relation with risk recognition degree by customs business of customs brokers and actuality insurance accident occurrence. These study finding that risk recognition by customs work area of customs brokers and actuality insurance accident occur did not agree. So customs brokers more elevate risk recognition of entry field, origin/trademark right, HS and customs tariff application, customs refund, price estimation that are high the insurance accident rate. and they may have to do emphasis administration through employee education and ability elevation. Specially, operation risk that is produced from charge employee's simplicity mistake who tax invoice omission, a tax use mistake, document nondelivery, notice dispatch delayed action, may have to manage through moral management and employee bylaws and education, employee guidance etc. Also, they publicize these contents to import and export enterprise, and practice risk management of high risk business in priority through education and public information. so we will have to make can do more effective risk management.

Advanced countries have mandated applying BIM in construction projects. Also, Public Procurement Service has planned to mandate applying BIM to all construction project that ordered in PPS from 2016 in KOREA. However, now Seumter that is building administration system is not supported BIM based construction license BIM information from Seumter. Thus, despite the applicant is preparing a BIM model, they do not take advantage of BIM information in Seumter. In previous studies. We developed a BIM based building approval submission system. In this study, we verified the system that developed in previous research. As a result, requirement information input time reduction in Seumter system showed high satisfaction. But there was as low usability because building approval submission system cannot support some information for building approval in seumter. If the system will do utilization and management with the building approval system, the applicant can be using BIM base design document information and saving the time that takes at building approval submission. Study about the system improvement is required for application to building approval system.

In this study, it was intended to explore a way to build a DB which links the resources and areas and regions already registered as cultural assets in connection with a project which is newly building local culture and arts resources. Towards this end, this study first identified the type and scale of existing local culture and arts resources that could be linked. Following which, to link the local cultural resources and collected cultural assets, this study investigated the websites such as the Cultural Heritage Administration's National Cultural Heritage Portal, municipal and provincial tangible cultural festivals, municipal and provincial intangible cultural assets, and Gyeonggi Memory. Furthermore, this study identified the amount of information sources to be built and the current status of each information source to identify detailed information sources. Finally, the metadata of local culture and arts resources were presented by classifying them into material and publication data metadata, document metadata, audiovisual metadata, oral recording metadata, village information metadata, and personal information village information metadata.

주식 시장은 거래자들의 기업과 시황에 대한 기대가 반영되어 움직이기에, 다양한 원천의 텍스트 데이터 분석을 통해 주가 움직임을 예측하려는 연구들이 진행되어 왔다. 주가의 움직임을 예측하는 것이기에 단순히 주가의 등락 뿐만이 아니라, 뉴스 기사나 소셜 미디어의 반응에 따라 거래를 하고 이에 따른 수익률을 분석하는 연구들이 진행되어 왔다. 주가의 움직임을 예측하는 연구들도 다른 분야의 텍스트 마이닝 접근 방안과 동일하게 단어-문서 매트릭스를 구성하여 분류 알고리즘에 적용하여 왔다. 문서에 많은 단어들이 포함되어 있기 때문에 모든 단어를 가지고 단어-문서 매트릭스를 만드는 것보다는 단어가 문서를 범주로 분류할 때 기여도가 높은 단어들을 선정하여야 한다. 단어의 빈도를 고려하여 너무 적은 등장 빈도나 중요도를 보이는 단어는 제거하게 된다. 단어가 문서를 정확하게 분류하는 데 기여하는 정도를 측정하여 기여도에 따라 사용할 단어를 선정하기도 한다. 단어-문서 매트릭스를 구성하는 기본적인 방안인 분석의 대상이 되는 모든 문서를 수집하여 분류에 영향력을 미치는 단어를 선정하여 사용하는 것이었다. 본 연구에서는 개별 종목에 대한 문서를 분석하여 종목별 등락에 모두 포함되는 단어를 중립 단어로 선정한다. 선정된 중립 단어 주변에 등장하는 단어들을 추출하여 단어-문서 매트릭스 생성에 활용한다. 중립 단어 자체는 주가 움직임과 연관관계가 적고, 중립 단어의 주변 단어가 주가 상승에 더 영향을 미칠 것이라는 생각에서 출발한다. 생성된 단어-문서 매트릭스를 가지고 주가의 등락 여부를 분류하는 알고리즘에 적용하게 된다. 본 연구에서는 종목 별로 중립 단어를 1차 선정하고, 선정된 단어 중에서 다른 종목에도 많이 포함되는 단어는 추가적으로 제외하는 방안을 활용하였다. 온라인 뉴스 포털을 통해 시가 총액 상위 10개 종목에 대한 4개월 간의 뉴스 기사를 수집하였다. 3개월간의 뉴스 기사를 학습 데이터로 분류 모형을 수립하였으며, 남은 1개월간의 뉴스 기사를 모형에 적용하여 다음 날의 주가 움직임을 예측하였다. 본 연구에서 제안하는 중립 단어 활용 알고리즘이 희소성에 기반한 단어 선정 방안에 비해 우수한 분류 성과를 보였다.

In Korea, local government officials are in charge of buildings, and as such are supposed to review submitted documents related to the architectural administration to ensure that they comply with the legal standards. However, these officials generally put a greater emphasis on the preparation of the set of documents required for the administrative work than the content the documents contain. For this reason, many experts point out that the shortage of officials specialized in buildings and construction, as well as the lack of expertise among the building officials in the local governments, may result in repeated safety accidents during building construction. The purpose of this study is to propose the operational direction of a Regional Building Safety (RBS) center to secure the performance and safety of buildings by utilizing private resources. In this study, we carried out a pilot project to verify the effects of an RBS center and to derive the specific number of experts required. As a result, the technical matters were resolved in approximately 15% of the total cases of the document processing procedure, and the level of technical specialization among the officers has also been improved through the provision of guidance. The research findings support the validity and effects of the introduction of the RBS center. Finally, this study proposes (1) the types of RBS Centers that should be established, (2) the roles and business scope of the RBS Center, (3) the specific number of experts required, (4) the qualifications of the experts, and (5) the business regulations of the RBS Center.

Though the debate of the establishment time, place and characteristic of the first fisheries cooperatives in Korea has been existed, it is clear that they had been established in the neighborhood of Tongyeong during the period of Japanese colonial rule. But the objective, motive and historical background of the first fisheries cooperatives are still slightly vague. To explain and explore that of fisheries cooperatives, over 1,000 articles of media, about 100 document of the Japanese government-general of Korea and the annals of the Joseon dynasty, many of research paper and others were included and refined. Through the result of that process, three core factors were founded that affect both the emergence of fisheries cooperatives and relationship of the them. The first one is about the royal family's fishing area where in the neighborhood of Tongyeong. The next one is Kentaro Kashii who was called king or devil of the Korean fisheries industry and the last one is fishermen and their organizations including fisheries cooperatives. Some of the above and the fishing rights conflict that make a guidance for understanding them has not been clearly mentioned. The result of this study shows that the birth of the first fisheries cooperatives were caused by not only the Japanese government-general of Korea but mainly Korean fishermen's voluntary activity and free will against fishing rights conflict between them. And both of the first fisheries cooperatives had somewhat difference in their constitution of organization and their characteristics but it was a tragic irony that the more exploitation and despoliation were conducted by Japanese government-general and Japanese capitalist the more movement and activity of Korean were frequently and severely occurred. Even though the findings and results of this study would be a proof and helpful material for understanding the establishment and their activity of fisheries cooperatives in Tongyeong, more research and contribution would be need by members of fisheries academic and business world.

학교에서는 주어진 목표를 달성하기 위해서 상부교육 기관, 일반행정 기관, 지역사회의 유관 기관 및 각종 단체들과 밀접한 관련을 맺고 상호작용을 하는 수단으로 공문서를 이용해 왔다. 기존 전자상거래의 효율을 도모하기 위하여 XML/EDI이 사용되고 있는데, 이를 교육망에 도입하면 교육행정 업무 간소화에 크게 기여할 수 있다. 본 논문에서는 현재 각급 학교에 구축되는 교육정보유통 시스템에서 지원되지 못하는 문서처리를 가능하게 하고, 교육정보유통시스템에 추가할 것을 전재로 XML/EDI를 사용한 문서관리시스템을 구현하였다. 이를 위해서 교육망에서 현재 통용되는 문서를 분석하고, 그에 맞는 새로운 태그들을 개발 구현했다. 인터넷을 기반으로 한 본 시스템은 별도의 응용 프로그램을 강요하지 않고, XML로만 새로운 문서들을 정의하였고, 그에 맞는 DTD를 정의하였다. 그럼으로써, 교사들의 잡무를 줄여, 교사의 본업인 교수-학습에 전념할 수 있도록 하는데 기여한다.
