This fault diagnosis system consists of qualitative models, qualitative interpreter, and inference engine. Qualitative models are formed by analysis of the relationships between faults and behaviors of sensor trends, which are described by state transition trees. Qualitative interpreter outputs confidence factors with three qualitative quantities which represent the states of sensor trends. And then, the possible faults are detected by inference module which matches the states of trends within a window size with the qualitative models using the well-known min-max operation.

Korea's R&D investment has significantly increased in recent years and the quantitative outputs such as number of papers and patents have also increased with the investment. However, the quality of R&D outputs has not been fully addressed. In particular, quality of technical performance, such as the quality of patents, has attracted little attention. In this paper, a Data Envelopment Analysis (DEA) method was used to construct models for efficiency analysis of R&D investment, focused on quality of technical performance. Indices were proposed to analyze the quantitative and qualitative efficiencies of R&D investment. In order to effectively analyze R&D efficiencies, the measurement units of the input and output variables were standardized. Based on cases of livestock quarantine R&D projects of Korea, the quantitative and qualitative efficiencies of national R&D projects were analyzed and factors that would influence R&D efficiencies were identified. This paper suggests that both quantitative and qualitative efficiencies should be considered when measuring R&D efficiency. Also, it is recommended to carefully consider the characteristics of R&D projects during project selection stage.

In knowledge-based economy, a nation's knowledge resources are critical factors for its competitiveness with other nations. This study analyze the quantitative and qualitative share of ISI publication of Korea as the level of knowledge resource by using the SCI database. This paper uses RCI(Relative Citation Impact) index for the qualitative analysis. The result shows that Korea's qualitative share of ISI publication measured by citation is relatively small than the quantitative share meaured by number of papers. In research field, natural sciences and medical sciences are relatively weak than engineering and agriculture.

Purpose: This study examines the history of the evolution of MS analysis and intends to consider the future direction of technological development through the difference from the latest technology, SIFT-MS. Research design, data and methodology: A method of analysis will be described in detail at the below by SIFT-MS (Selected Ion Flow Mass Spectrometry), which is a technology developed by a company called SIFT Technologies. Results: The initial concept of mass spectrometry was begun in the late 1890s, and it continues to evolve even after the 21st century through the ripening stage of the 20th century. The development process of mass spectrometry by year has been described in detail in the Main text. Conclusions: Mass spectrometry, qualitative and quantitative analysis of substances plays a very important role in the research and medical fields. The development of these analytical methods is expected to continue in the future, and faster and more accurate qualitative analysis and mass spectrometry will be developed than the level currently reached. In addition, it is expected that hardware and software will be configured so that non-analysis experts can handle it easily, and it will be used as a technology that is more closely related to our lives.

Importance of technology evaluation cannot be overemphasized to support the effective investment policy. Most of the technology evaluation relies on either quantitative analysis for the value or qualitative comparison due to some attribute. When qualitative comparison is made, typically not only individual attribute. but also overall score is evaluated by the committee of experts. In this paper, we consider the qualitative evaluation procedure used in a venture incubating center and validate if the relationship between the average score of individual attribute and the overall score is significant. Additionally, we identify if the initially evaluated scores are good indicators for the realized future value of technology. Structural equation modeling approach is used and we expect that our approach can make important contributions on improving the currently used technology evaluation method.

Plants which are having conditions of high temperature and pressure always are exposed to danger. In order to prevent unexpected accidents, safety management that can effectively and appropriately examine facilities is required in plant operation. RBI(Risk-Based Inspection) technology in API 581 is one of standard management technique for evaluating risk on petroleum plants. There are qualitative and quantitative assessments in RBI methodology. Quantitative evaluation step is complex and required much information, so high-risk facilities in plant are selected firstly by qualitative method. Qualitative RBI is performed by choosing the answer in prepared questionnaire. However, it is difficult to believe thoroughly results from survey including ambiguous information. In this study, the procedure of qualitative RBI analysis with considering probability distribution concept were proposed by using Monte Carlo simulation method in order to increase reliability in spite of uncertain factors. In addition, qualitative risk of cooling system for LNG plant was evaluated using proposed procedure. Although 20 items of total 39 assessment items are applied to uncertain factors, risk section of high probability(89%) were verified. The detailed results were described in manuscript.

This article provides how to implement the use of Realistic Mathematics Education (RME) in a teaching a function at a school to improve the equity based on the gender in students' mathematization for their mathematical thinking using technology. This study was planed to get research results using the mixed methodology with qualitative and quantitative methodologies. 120 middle school students participated in the study to bring us data about their mathematical achievement. Through the data analysis used by ANCOVA for the qualitative method, the students with the experiment of the mathematization based on technology excelled the other groups of students who were not provided with technology or both of them. Through the data analysis used by the constant comparative method for the qualitative data, the technology environment had helped the female students manipulate learning trends easily, strong construction on horizontal mathematization, depending on discussion with peers, and more reflexive thinking using a calculator. This means that teachers can put careful assignment on each category of mathematization regarding the gender. The study results in a lot of resources for teachers to use into their teaching mathematics for improving students' equity in interactive technology environment.

본 연구에서는 정부출연연구기관 중 하나인 K 연구원 사례를 활용하여 연구개발 프로젝트에 대한 정성평가 결과와 정량평가 결과를 비교 분석함으로써 연구개발 프로젝트 성과평가 체계 개선을 위한 시사점을 도출하였다. 비교 분석을 위해 정성평가 결과는 국가과학기술연구회 규정에 따라 진행된 실제 평가결과를, 정량평가 결과는 연구개발 프로젝트의 산출물 데이터를 기반으로 자료포락분석(data envelopment analysis) 결과를 활용하였다. 비모수 상관관계 분석(Kendall's ${\tau}$)을 비롯한 다양한 분석 결과, 정성평가와 정량평가 결과 사이에는 분명한 차이점이 있는 것으로 확인되었다. 따라서 단순 정성 또는 정량평가로 연구개발 프로젝트를 평가하기보다 정성 및 정량평가가 상호보완적으로 진행된다면, 평가 시 각 연구개발 프로젝트의 특성을 반영함과 동시에 객관성도 보다 확보할 수 있을 것으로 기대된다.

오늘날 국가와 기업의 연구 개발 투자 및 경영 정책 전략 수립에서 미래 부상 기술 예측은 매우 중요한 역할을 한다. 기술 예측을 위한 다양한 방법들이 사용되고 있으며 특허를 이용한 기술 예측 또한 활발히 진행되고 있다. 특허를 이용한 기술 예측에는 전문가들의 평가와 견해를 통한 정성적인 방법이 주로 사용되어 왔다. 정성적인 방법은 분석 결과의 객관성을 보장하지 못하고 분석에 많은 비용 및 시간이 요구된다. 이런 문제점을 보완하기 위해 최근에는 텍스트 마이닝을 이용한 특허 데이터의 정량적인 분석이 이루어지고 있다. 텍스트 마이닝 기법을 적용함으로써 특허 문서의 통계적 분석이 가능하다. 본 논문에서는 텍스트 마이닝과 ARIMA 분석을 이용한 기술 예측 방법을 제안한다.
