There are many statistical information sites as the use of internet is increased quickly in recent years. In this paper, we explore and analyze internet sites for statistical information such as statistical survey system, education, database, and terminology. And then we classify these sites to apply statistical information to some particular spheres easily. In so doing, this study result aims at enhancing our understanding of internet sites for statistical information.

과학기술 문헌의 전문용어 인식 분야는 지금까지 다양한 통계적 방법론을 사용하여 용어 인식 정확률을 향상시키기 위하여 연구되어 왔다. 하지만 기존의 연구는 단일-코어 또는 단일 머신 상에서 수행되었기 때문에, 폭발적으로 증가하는 문헌들에 대한 실시간 분석 요구를 처리할 수 없는 상황에 직면하고 있다. 본 논문에서는 전문용어를 인식하는 과정에서 병목현상이 발생하는 작업을 '후보용어 추출 과정'의 언어처리부분과 '용어 가중치 할당 과정'에서 통계정보를 취합하는 부분으로 분류하고, 각 작업을 분산병렬 처리 기반의 맵리듀스 작업을 이용하여 해결하는 전문용어 인식 방법을 구현하고 실험하였다. 실험은 확장성과 분산 병렬 처리 환경 최적화 두 가지로 수행하였고, 첫 번째 실험에서 12개의 노드를 사용하여 분산 병렬 처리하였을 때 단일 머신을 사용한 경우보다 11.27배의 처리속도 향상을 보였다. 두 번째 실험에서 1)기본 환경, 2)복수 리듀서, 3)컴바이너, 4) 2)와 3)의 조합에 대하여 수행하였고, 3)컴바이너 사용이 가장 우수한 성능을 보여 주었다. 본 논문에서 구현된 전문용어 인식 시스템은 대용량 과학기술 문헌에 대한 지식 추출 작업속도 개선에 기여하였다.

이 논문에서는 현재 중등학교 수학의 통계교육에서 다루고 있는 통계용어의 의미상 혼선과 애매한 내용을 수학교사를 대상으로 알아보고, 표본평균의 확률분포에 대한 지도 영역에 있어서 표집(sampling, 표본추출)의 문맥에서 표집오차(sampling error)와 표본평균의 표집분포(sampling distribution)라는 용어를 도입하여 일관성 있게 사용할 것을 제안하였다. 현행 중고등학교의 수학과의 통계의 용어 정의와 개념설명에 있어서, 교육부가 검정한 12종의 검정 교과서와 국정교과서 간에서도 차이는 물론 의미의 혼선과 함께 정의의 일관성의 부족은 통계를 교육하는 수학교사와 학생들에게 심각한 오개념을 형성하게 만들고, 그 애매함으로 인하여 통계학의 학문 자체에 대한 흥미와 태도의 정의적인 면에서 부정적인 영향을 주고 있음이 발견되었다 본 연구에서는 표본평균의 확률분포의 효율적인 지도를 위한 표본오차 대신에 표집오차를 사용할 것과 표집분포의 용어를 도입함으로서 통계용어의 정확한 사용을 동하여 교사와 학생들에게 통계용어의 올바른 개념의 형성과 이해는 물론 통계교육의 일관성과 계열성 유지의 필요성을 제기하였다.

국가간 혹은 기관간의 통합되고, 상호 인정할 수 있는 분석법의 기본 지침이 확립되면, 서로 다른 실험 여건이라 할지라도 공통된 실험 지침에 따라 수행된 연구 및 조사 결과를 생산할 수 있고, 결과를 비교 분석할 때 오류를 줄임으로써 국가 정책 수립을 위한 과학적이고 정확한 자료제공을 할 수 있다. 현재, 우리나라는 분석과 관련한 통합된 우수실험실규범(Good Laboratory Practice) 운용체계나, 정부기관에서 발행된 각종 공정 시험법 내 기초적인 기준(criteria)이 미흡하며, 용어나 그 용어의 정의에 대한 통일성을 찾기가 쉽지 않다. 따라서 신뢰성 있는 분석결과의 상호인정을 위해서 전문가들로 구성된 통합 지침의 확립이 절실히 요구된다. 이런 이유로 본 총설에서는 정량분석의 기초인 검량선 작성법에 대해 ISO, ACS, ASTM, AOAC, CODEX 및 관련 서적과 연구 논문을 통해 지침과 실례 등을 살펴보고 일상적인 분석업무 중 발생하는 오류 등에 대하여 설명하였다.

The objective of this research is the development of the Automatic Subjective Assessment System (ASAS). The proposed subjective assessment system is designed to evaluate human emotion and sensibility (or "gamsung" in Korean terminology) with subjective responses of volunteers about the experiment of emotion and sensibility. Once volunteers enter their subjective responses about the experiment into the developed system, the proposed system can automatically generate statistical results of human emotion and sensibility using Statistical Package for the Social Sciences (SPSS). Then, the system stores the statistical results in the database which will be open to public through internet. The proposed system will be integrated into the universal" gamsung" assessment system for evaluation of human emotion and sensibility.

This paper reviews the most central analytical and methodological issues that arise in developing national STI strategies. First, an outline of the relationship between national innovation systems and the strategic dimension is presented. The paper shows that science, technology and innovation strategy are often used in different forms and that there is no common understanding yet of the actual meaning and coverage of these strategies. The paper develops the terminology from a discussion of different approaches towards company innovation processes analyzing their evolution in different socioeconomic environments and the role and impact of science, technology and innovation policy on company innovation processes. Based on this conceptual understanding the paper defines national science, technology, innovation, and STI strategy and explains the basic terminology. From these definitions, the strategic dimension including the impact on the stakeholders is discussed. It is shown that a major success factor for STI strategy development is the involvement of stakeholders to vary and extend their use of their portfolio of instruments. Moreover it becomes evident that stakeholders follow their own interests which aren't necessarily in the interest of the national STI strategies. The analysis shows advantages and disadvantages as well as potentials and limitations of different approaches to develop STI strategies in their ability to describe the reality of innovation processes and to allow conclusions about the relationship between innovation policy and the innovation processes implemented by companies. It is shown that knowledge of these limitations is an important factor to consider in designing consistent and coherent national STI policy which aims at supporting innovation eventually. Finally the paper concludes that the STI policy mix concept needs a more systemic development approach which is integrated in the national STI strategy development and implementation.

In this paper, we have proposed Auto-TUS, an automatic transcription module of three union symbols-hyphen, dash and tilde (‘­’, ‘―’, ‘∼’)-using their linguistic contexts. Few previous studies have discussed the problems of ambiguities in transcribing symbols into Korean alphabetic letters. We have classified six different reading formulae of the union symbols, analyzed the left and right contexts of the symbols, and investigated selection rules and distributions between the symbols and their contexts. Based on these linguistic features, 86 stereotyped patterns, 78 rules and 8 heuristics determining the types of reading formulae are suggested for Auto-TUS. This module works modularly in three steps. The pilot test was conducted with three test suites, which contains respectively 418, 987 and 1,014 clusters of words containing a union symbol. Encouraging results of 97.36%, 98.48%, 96.55% accuracy were obtained for three test suites. Our next phases are to develop a guessing routine for unknown contexts of the union symbols by using statistical information; to refine the proper nouns and terminology detecting module; and to apply Auto-TUS on a larger scale.

A statistical analysis of the diagnostic value for 244 aspiration biopsy cytology(ABC) among a total 1,043 cases from various sites was performed. ABC, using diagnostic terminology similar to that of a surgical pathology reports, was compared to the final tissue diagnosis. For the entire series, a sensitivity of 91.8%, a specificity of 99.3%, a positive predictive value of 98.9%, a negative predictive value of 94,8%, and an efficacy of the test of 96.3% were shown. There were 8 false negative and 1 false positive diagnosis. The diagnostic accuracy was 89.8%. Those results indicate that the ABC is a considerably highly accurate procedure that should be routinely employed.

A stochastic process {$A_n$, n = 1, 2, ...} is an arithmetic process (AP) if there exists some real number, d, so that {$A_n$ + (n-1)d, n =1, 2, ...} is a renewal process (RP). AP is a stochastically monotonic process and can be used for modeling a point process, i.e. point events occurring in a haphazard way in time (or space), especially with a trend. For example, the vents may be failures arising from a deteriorating machine; and such a series of failures id distributed haphazardly along a time continuum. In this paper, we discuss estimation procedures for an AP, similar to those for a geometric process (GP) proposed by Lam (1992). Two statistics are suggested for testing whether a given process is an AP. If this is so, we can estimate the parameters d, ${\mu}_{A1}$ and ${\sigma}^{2}_{A1}$ of the AP based on the techniques of simple linear regression, where ${\mu}_{A1}$ and ${\sigma}^2_{A1}$ are the mean and variance of the first random variable $A_1$ respectively. In this paper, the procedures are, for the most part, discussed in reliability terminology. Of course, the methods are valid in any area of application, in which case they should be interpreted accordingly.
