인터넷 사용자의 급속한 증가로 여러 종류의 인기 웹사이트들이 생겨나고 있으나, 웹사이트의 품질을 사용자 관점에서 종합적이고 체계적으로 비교 및 평가하는 선정기법에 대한 연구는 미약한 상황이다. 일반적으로 웹사이트 품질을 평가하는 관점은 블랙박스, 화이트박스, 그레이박스 관점으로 구분할 수 있다. 본 논문에서는 최적의 웹사이트를 선정하기 위해 사용자 입장에서 블랙박스 관점으로 AHP(Analysis Hierarchy Process)기법을 사용하였고, 웹사이트의 품질은 국제표준 IS0/1EC 9126에서 규정하고 있는 6가지 소프트웨어 품질 특성 중에서 효율성, 사용성, 호환성을 고려하였다. 현재 인터넷상에서 운영하고 있는 웹사이트들에 대한 실증적 분석을 통하여, 본 논문에서 제시한 웹사이트 선정기법 및 품질 평가에 관한 연구가 최적의 웹사이트를 선택하는데 적용 가능한 것임을 보여준다

Korean e-Government web site has been evaluating as a distinguished government, ranked 5th of the 119 countries in the "Global e-government readiness index report 2005" by UN in 2006. However we have to focus poor rate of utilization in proportion to its high evaluation of e-Government ranking. These reason probably did not reflect the requirements of user to build and operate e-Government web site. In this paper we will provide the important factors to consider to build and operate e-Government web site. For this, we analyze the relative importance for evaluation factors of e-Government web site using AHP(Analytic Hierarchy Process).

This study examined the characteristics of total consumers' anti-sites on on-line and their changes according to the establishment year of consumers' anti-sites, the activities and the evaluation of consumers' anti-sites and their differences according to the characteristics of consumers' anti-sites. Total 649 consumers' anti sites were analyzed for examining the characteristics of total consumers' anti-sites and 18 anti sites were selected for examining the activities and the evaluations of consumers' anti site. The anti sites were evaluated by the index of using in preceding research. The result showed that about 90% of total consumers' anti-site were not activated, only a few consumers participated even in the activated sites, most activity of the anti-site were operated only on on-line not off-line, over half of anti-sites targeted to the company in the type of the subject of anti-site, and the majority of the external shape of anti-site were cafe. On the change of characteristics according to the opening year, the proportion of cafe and the sites acting on both on-line and off-line were increased year by year. The number of anti-sites was decreased since 2005 and the proportion of highly activated sites was lowest in 2005. On the activity of anti-sites, the number of providing the information were more than the number of presenting the complaint among the bulletin writings. The number of the bulletin writing were more in highly activated sites than in low activated sites. most of highly activated sites were problem solving type compared to the low activated sites. The number of the bulletin writings in company anti-sites were the most among three type of subject of anti-site. The number of the bulletin writings in cafe type were more than in home-page type. On the evaluation of consumers' anti-sites, most of the sites didn't update the notices and provided incomplete information how consumers participated in the protesting movements. The highly activated sites functioned better in most parts in providing a information, connection with other consumer and site manager, management of the site.

본 논문은 멀티미디어 웹 사이트의 사용성 품질 평가를 위한 품질 기준과 웹 메트릭을 제안하고자 한다. 최근 들어 웹 사이트의 활용이 새로운 기술과 접목되어 산업 전반에 결쳐 다양하게 사용되고 있다. 또한 초고속 통신망이 일반화되면서, 그동안 네트워크의 속도 문제로 제한적으로 사용되었던 멀티미디어의 활용이 증가하면서 멀티미디어 웹 사이트가 증가하는 추세이다. 따라서 본 논문은 기존의 소프트웨어 공학, HCI, 하이퍼미디어 분야에서 연구되어온 HTML기반의 품질 평가의 연구를 멀티미디어 웹 사이트로 확장하고, 멀티미디어 웹 사이트에서 큰 비중을 차지하는 플래시 사용성을 접목하여 새로운 웹 메트릭을 제안하였다. 본 논문에서 제안된 웹 메트릭은 전문가 평가를 통하여 검증을 하였다. 또한 박물관을 도메인으로 하여 웹 어워드 코리아에서 수상한 웹 사이트와 비수상 웹 사이트를 정량적이고 정성적인 품질 평가를 통하여, 운용중인 멀티미디어 웹 사이트의 품질 평가가 가능한 것을 비교 검증하였다. 본 논문으로 향후 고품질의 멀티미디어 웹 사이트 개발의 기반이 될 것이다.

Background/Aims: In stereomicroscopic sample isolation processing, the cutoff value (≥4 mm) of stereomicroscopically visible white cores indicates high diagnostic sensitivity. We aimed to evaluate endoscopic ultrasound-guided tissue acquisition (EUS-TA) using a simplified stereomicroscopic on-site evaluation of upper gastrointestinal subepithelial lesions (SELs). Methods: In this multicenter prospective trial, we performed EUS-TA using a 22-gauge Franseen needle in 34 participants with SELs derived from the upper gastrointestinal muscularis propria, requiring pathological diagnosis. The presence of stereomicroscopically visible white core (SVWC) in each specimen was assessed using stereomicroscopic on-site evaluation. The primary outcome was EUS-TA's diagnostic sensitivity with stereomicroscopic on-site evaluation based on the SVWC cutoff value (≥4 mm) for malignant upper gastrointestinal SELs. Results: The total number of punctures was 68; 61 specimens (89.7%) contained stereomicroscopically visible white cores ≥4 mm in size. The final diagnoses were gastrointestinal stromal tumor, leiomyoma, and schwannoma in 76.5%, 14.7%, and 8.8% of the cases, respectively. The sensitivity of EUS-TA with stereomicroscopic on-site evaluation based on the SVWC cutoff value for malignant SELs was 100%. The per-lesion accuracy of histological diagnosis reached the highest level (100%) at the second puncture. Conclusions: Stereomicroscopic on-site evaluation showed high diagnostic sensitivity and could be a new method for diagnosing upper gastrointestinal SELs using EUS-TA.

본 논문에서는 원자력발전소 부지의 안전성 평가 방법으로서 부지의 인구를 평가하는 USNRC의 SPF를 보다 발전시켜 정상 가동시나 사고시 방출되는 방사성 물질이 대기에로의 확산으로 인하여 주거 인구가 받는 영향을 고려하여 SPMF를 정의하고 고리 부지에 대한 SPF와 SPMF를 비교함으로써 SPMF모델의 타당성을 검토했다. 아울러 미국 주요 발전소와 국내 발전소 부지의 SPF를 비교하여 국내발전소 부지의 상대적 안전성을 평가했다.

This research investigated consumer's usage of, evaluation on and satisfaction of the Auction Site, with a view to analyze the key factors influencing a commission paid Auction Site. The findings of results from the analysis are summarized as follows. First of all, the consumer group at the age equal to and less than 20 years old showed the highest purchasing frequency, and the consumer group with a household income less than 2,500,000 won showed the highest number of hours on the site. Secondly, the evaluation index showed that consumers think highly of the complaint resolution process, and, especially, the aged consumer group respected the Auction Site's level of confidentiality of transaction and privacy. Thirdly, among consumers' satisfaction, subdivided by types, price satisfaction was the highest followed by quality satisfaction, settlement satisfaction, delivery satisfaction, information satisfaction and AS satisfaction, in that order. Fourthly, in the event consumers used the commission paid Auction Site, the number of times it has been used, evaluations related to information provision and evaluations on confidentiality of transactions and privacy are influential parameters.

Community dynamics of benthic macroinvertebrates and biological evaluation of water quality were investigated at Gigyecheon of Pohang and Gyeongju, Korea. The survey was carried out at 8 sites from May to October, 2017. As a result, total of 104 species under 54 families, 15 orders, 8 classes in 4 phyla with 5,052 individuals were revealed. The number of species was the most abundantly identified in aquatic insects, 76 species under 34 families, 6 orders. Among them, the order Odonata was the most abundant taxon as 21 species(20.2%). The most abundant individuals were collected in the phylum Mollusca as 1,453 individuals(28.8%). Various species appeared dominantly at each site by season, and the most dominant species was Caridina denticulata denticulata belonging to the class Malacostraca with 0.08 of dominance index. According to the results of community structure analyses, the diversity and richness indices were the highest at site II, the evenness index was the highest at site I, and the dominance index was the highest at site IV. The number of species and individuals of gathering collectors were the highest among functional feeding groups. Those of sprawlers were the highest among habitat orientation groups. The ESB showed a tendency to change according to season and site, and it was the highest in May at most surveyed sites. The KSI was also somewhat fluctuated according to season and site. From these indices, average biological water quality was evaluated as class II.
