이상적인 GIS 예방진단 장비라 한다면 최소의 비용과 규모로 설치되어 결함은 빠짐없이 수 있어야 하며, 검출된 신호가 결함신호인지 잡음인지를 명확히 식별하여 필요한 정보만을 운전자에게 전달하여야 한다. 즉, 검출된 신호가 결함에 의한 것이라면 결함의 종류와 결함의 상세위치, 위험한 정도, 후속 필요조치 등에 대한 정보를 운전자에게 제공할 수 있어야 한다. 그동안 국내에서는 이상적인 기술목표를 향하여 꾸준히 연구해 왔으며 이제는 센서기술이나 센서 배치, 신호해석기술, 시스템 설계 제작기술, 시스템 운영 등에서 세계적 수준에 도달했다고 볼 수 있으나 외국에서도 마찬가지이기는 하지만 위험도 평가분야는 아직은 미흡한 상태이다. 현재 산업계와 학계, 연구계에서 연구개발을 활발히 하고 있으므로 수년 내에 만족할 수준까지 도달할 수 있을 것으로 전망된다.

부산항 해운항만산업은 부산 전체 산업 매출의 8.7%를 차지하고 있음에도 불구하고 해운항만산업의 규모가 상대적으로 영세해 산업역량 강화를 위한 산업 고도화 방안 마련이 시급한 상황이다. 한국정보화진흥원에서 산업별 정보화 수준을 진단한 결과 해운항만산업이 속한 운수업의 IT 활용지수는 다른 산업에 비해 낮은 수준으로 진단된다.

The government of the Republic of Korea is conducting quality management of public open data by conducting a public data quality management level evaluation. Public open data is provided in various open formats such as XML, JSON, and CSV, with CSV format accounting for the majority. When diagnosing the quality of public open data in CSV format, the quality diagnosis manager determines and diagnoses the domain for each field based on the field name and data within the field of the public open data file. However, it takes a lot of time because quality diagnosis is performed on large amounts of open data files. Additionally, in the case of fields whose meaning is difficult to understand, the accuracy of quality diagnosis is affected by the quality diagnosis person's ability to understand the data. This paper proposes a domain discrimination model for public open data in CSV format using field names and data distribution statistics to ensure consistency and accuracy so that quality diagnosis results are not influenced by the capabilities of the quality diagnosis person in charge, and to support shortening of diagnosis time. As a result of applying the model in this paper, the correct answer rate was about 77%, which is 2.8% higher than the file format open data diagnostic tool provided by the Ministry of Public Administration and Security. Through this, we expect to be able to improve accuracy when applying the proposed model to diagnosing and evaluating the quality management level of public data.

As education is one of key factors to improve national competitiveness, quality education becomes a top priority in all countries around the world. In South Korea, The Basic Skills Competency Test is administered annually to select below-basic third graders and provide intervention programs. The Basic Skills Competency Test was designed to diagnose the minimal competency of third graders according to a national-level standards. The purpose of this study was to analyze standard-setting procedures and set cut-off scores. This study offered the empirical evidence that standard-setting is generally applicable in schools by the modified Ebel method. More future researches addressing appropriate and efficient standard-setting methods in real school situations are needed to be taken in.

The pursuit of strategic infomatization plays a critical role in increasing the competitiveness of domestic companies in this rapidly changing era. In particular, infomatization of small and medium construction companies is lower than that of large companies in terms of company size and the range of infomatization. Also, the environment for the infomatization is very unfavorable. Thus, to ensure effective infomatization of small and medium construction companies, it is critical to assess the current level of infomatization, and ensuing initiatives should start by gaining an accurate understanding of the level that should be reached in the future by each stage. This paper purports to develop indices which are needed for the diagnosis of current level of infomatization and for the understanding of current realities, problems and requirements that the small and medium construction companies face while pursuing infomatization today.

A lack of basic academic skills of junior college students has negatively impacted on the quality of vacational education and student dropout prevention, and yet it is true that there still are unclear alternatives or solutions to come up with that concern. As a way to find out the actual levels of basic academic skills of junior college students and educational efforts to improve these skills, the study investigated prior studies and benchmarked strengths and weaknesses of the related educational programs and supporting systems operated by ten junior colleges around the nation. Further, the study addressed emerging issues and challenges related to basic academic skills, based on the case study of D college. Major research methodologies included literature review, surveys for students and faculty members and focus-group interviews of faculty members in order to examine the states of students' basic academic skills in the area of language, in particular. Accordingly, the study proposed several suggestions with which educational practitioners could assist in supporting students to acquire improved basic academic skills(such as the development of a competence-based curriculum, implementation of reliable diagnosis tools and supporting educational systems for evaluating students' basic academic skills and upgrading of diverse teaching and learning resources and methods).

Due to the improvements in circuit design and manufacturing technique, the complexity of a circuit is growing. Since the complexity of a circuit causes high frequency of faults, it is very important to locate faults for improvement of yield and reduction of production cost. But unfortunately it takes a long time to find sites of defects by e-beam proving if the physical level. A fault diagnosis algorithm in the Sate level has meaning to reduce diagnosis time by limiting fault sites. In this paper, we propose an efficient fault diagnosis algorithm in the logical level. Our method is hybrid fault diagnosis algorithm using a new fault dictionary and additional fault simulation which minimizes memory consumption and simulation time.

정부는 공공데이터의 품질 관리를 위하여 공공데이터 품질관리 수준평가를 진행하여 공공데이터 품질을 관리하고 있다. 파일 형식의 공공데이터를 진단 시 품질진단 담당자가 대량의 파일데이터를 필드명과 필드 내 데이터에 의존하여 수작업으로 도메인을 판단하여 진단한다. 때문에 품질진단의 정확성을 신뢰하기 어렵고 진단에 많은 시간이 소요된다. 본 논문은 파일형식의 공공데이터 품질진단의 정확성을 확보하고 진단 소요시간을 단축하기 위해 데이터 분포 통계를 이용한 CSV 형식의 공공데이터 도메인 판별 모델을 제안하였다. 제안된 모델을 적용하면 공공데이터 품질의 정확성을 향상하고 진단 소비 시간을 단축시킬 것으로 기대된다.
