In this paper, we derived 7 reliability measurement factors for effective web site construction through literature research and empirically measured reliability of the web site using "Xenu" and "Yslow" which are reliability measurement tools. We selected and tested total 12 domestic and foreign web sites. As a result of measuring those 12 web sites, the reliability level was varied in a number of aspects according to 7 measurement factors, and we suggested alternatives based on those 7 factors in order to build the effective web site.

대기중의 휘발성 유기화합물(VOC)측정의 중요성이 날로 커지고 있어 많은 연구자들의 관심을 갖고 이에 대한 연구와 측정이 이루어지고 있다. 대기중의 VOC는 0.1 ∼ 10 ppb수준의 매우 미량으로 존재하고 있어 정확한 측정이 어려운 경우가 많다. 시료의 채취과정에서 부터 분석과정, 그리고 calibration과정등 많은 측정 불확도 요인이 있어 이를 잘 파악하지 않을 경우 측정결과의 신뢰성이 크게 떨어질 수 있다. 그러므로, 본 연구에서는 이러한 측정 불화도 요인을 체계적으로 파악하여 정확한 VOC측정을 위해서 어떠한 측정 불확도 요인이 중요하고, 이러한 주요 측정불확도 요인을 최소화하기 위해서는 어떠한 점을 주의하여야 하는지를 조사하고저 하였다.

Discourse analysis is useful for examining discourse characteristics of dementia patients and differentiating them from normal adults. However, inconsistent tasks, transcription methods and measures have been utilized, thus analyses were inevitably unsystematic. The purpose of this study was to investigate tasks, transcription methods and measures of discourse studies in dementia. Studies on dementia discourses written in English were collected via Scopus database containing abstracts and citations from 2005 to 2014, and were analyzed in detail. From the results, the most frequently used task was 'storytelling-topic'. It was observed that use of consistent transcription conventions rendered more reliable transcription data. Measures could be categorized into coherence, cohesion, productivity, propositional syntactic lexical analysis, and fluency, and each category belonged to discourse processing levels (i.e., processing of conceptual networks, propositions, and natural language units). In conclusion, future research warrants not only utilization of discourse tasks depending on dementia types and features, but also application of consistent transcription conventions. Additionally, measures based on the discourse processing theory would enable us to systematically interpret discourse studies.

We analyzed 53 representative Korea oriental medicine web sites to measure the credibility and satisfaction using objective valuation basis. First we analyzed qualitatively the general sites' characteristics composed of operational status, kernel service, organization and payment. Secondly we calculated the sites' credibility categorized as expertise factors, trustworthiness factors, sponsorship factors and other factors to deduce the key factor. we expect the result can be used as the indicator for developer to improve the Korea oriental medicine web sites. And we expect the result can be used as the objective credibility for the web user to confirm the contents of Korea oriental medicine web sites.

측정의 소급성과 신뢰성을 확보한다는 전제하에 오차의 개념을 버리고 측정시의 측정불확도를 분석하는 것이 측정과학에 있어서 세계적인 추세이다. 본 논문에서는 전달표준인 열전압변환기를 사용하여 고주파전압계의 정밀 교정에서 불확도를 산출하기 위하여 수학적 모델을 설정하고 측정에 관계되는 모든 불확도 요인을 분석하였다. 케이블의 영향과 열전대감지기와 직류전압계의 상관관계, 직류소스, RF소스, 감쇠기, 반사계수와 DUT 등 측정에 있어서 관계되는 모든 불확도요인을 분석하여 확장불확도를 산출하였다.

본 연구는 서비스업에서 서비스 품질을 측정하는 것에 있어서 표준과 기대치에 관한 비교다. 외식산업에서의 기대의 개념은 서비스 품질을 측정한다는 것으로 이를 표준화하기 위해 광범위하게 사용되었다. 그러나, 서비스 품질 측정에 있어서 기대치가 당위성과 신뢰성에 의해 많은 연구자들에 의해 비평되었다. 이 연구의 목적은 기대치에 통한 서비스업에서의 서비스 품질을 측정한다는 것이다. 본 연구는 다음과 같은 한계점을 가진다. 첫째로, 연구의 표본수가 적기 때문에 분석에 있어서 신뢰성이 떨어졌다. 둘째, 한정된 한국의 호텔을 이용했던 여행자에 한하여 설문을 했기 때문에 객관성이 결여될 수가 있다. 셋째, 총체적인 서비스 품질과 고객 만족의 측정은 하나의 항목 저울과 이와 같이 그것을 사용하면서 수행되었기 때문에 이들의 신뢰성을 추정하는 것이 불가능했다. 연구결과 소비자가 서비스의 평가를 위한 비교 기준으로서 기대치에 대한 4개의 다른 수준을 가진 요인을 사용하였다. 본 연구에 있어서 기대의 개념이 고객 만족에 서비스 품질보다 관계가 높다는 것을 밝힌다.

The purpose of this study was to develop and validate a scale of Korean elementary teachers' mathematics beliefs. We examined 299 elementary teachers' mathematical beliefs using 30 items, out of which 12 items covered beliefs about the nature of mathematics and 18 items covered beliefs about mathematics teaching and learning. In the first stage, we performed exploratory factor analysis using 149 survey data to examine the factor structure. In the second stage, we performed confirmatory factor analysis using 150 survey data. Building upon previous studies, we examined the construct validity of three different models to find the best factor structure. The study results indicate that the four-factor model with 14 items provides the best fit for the data: transmissive view of mathematics, constructivist view of mathematics, transmissive view of teaching and learning, and constructivist view of teaching and learning. The findings of the study reveal that each factor has adequate internal consistency and reliability. These results confirm that the beliefs scale is a reliable and valid measurement tool to measure Korean elementary teachers' mathematical beliefs. The implications of the study are discussed.

This research was conducted to develop a model appropriate for the measurement of information quality of UCC service site. The evaluation factors that reflect more improvement of the information utilization capability were verified. Enhancement of information utilization capability can control greater amount of information among the users and site companies, and among users. Therefore, Wikipedia, for example, provides a Web 2.0 based information quality that is more advanced than Web 1.0 by allowing effective control of information among the users. This type of information quality presents 'information reliability' and 'information stability' as evaluation factors added to the factors such as 'information sufficiency' and 'information usability.' Information reliability and information stability are essential factors that need to conduct an evaluation in the Web 2.0 environment that can distribute greater number of information in the environment where all the users serve as participants. Moreover, 'interesting information' and 'originality of information' suggests that information itself should include the attributes that can attract the attention of users, due to the nature of the Attention Economics, which points out one of the Web 2.0 phenomenon that the number of information consumers is smaller than that of information suppliers.

This study aims to define which factors will contribute to vitalization of Saemangeum New Port to secure international competitiveness in order to attract international shipping companies, shippers and forwarders in constructing Saemangeum New Port, and to propose subsequent implications. For research methods of the current study, a factor analysis and a decision making method of analytic hierarchy process(AHP) were used. Through precedent studies, total 11 measuring variables were selected including short entrance and exit channels, main infrastructure development project, tax cut and deregulation, and through a factor analysis, total 3 high rank evaluation factors including 'location and facilities', 'surrounding infrastructure and hydrophile property', and 'local policy and environment'. Analysis results summarizing a test of reliability of measuring variables in this study indicate that as Cronbach alpha coefficient of total 11 measuring variables were turned out to be over 0.8, it is surpassing general average 0.6, which means there is reliability.
