인터넷 포털은 목적 사이트에 가기 위해 온라인 이용자가 처음으로 접속하는 사이트를 의미한다. 성공적인 e비즈니스를 수행하기 위해서는 거대 회원을 확보하고 있는 인터넷 포털의 발전과정을 탐색하는 것이 매우 유익한 일임에도 불구하고, 아직까지 포털 기업의 발전과 진화과정에 대한 심층적인 연구는 거의 없는 실정이다. 본 연구의 목적은 인터넷 포털 기업의 발전과정을 심층적, 정성적으로 분석하는 것이다. 이를 위해 분석을 위한 변수로 $2{\times}2$ 매트릭스를 제시하고 이들이 포털 기업의 발전과정에서 어떤 영향을 미치고 있는지를 분석하였으며, 이를 입증하기 위해 국내 주요 포털 기업에 대한 사례분석을 실시하였다. 사례분석의 결과 인터넷 포털 기업은 모두 4C를 수익화와 연결시키는 전략을 추진하고 있음을 볼 수 있었다. 또한 이와 같은 수익화의 실현을 위해서는 커뮤니티의 역할이 매우 중요함을 도출할 수 있었다.

이 연구는 포털 편집판에 게시된 언론사로부터 전재 받은 뉴스기사에 딸린 댓글의 명예훼손행위를 포털의 작위의무에 따라 판단한 서울중앙지방법원의 법리를 비판적으로 분석하고 있다. 편집판에 게시하는 언론기사의 진위를 포털이 확인하도록 요구하고, 그 기사에 대한 명예훼손적 댓글을 삭제하도록 발행자 수준의 작위의무를 강제하는 것은 결국 사적 검열로 이어져 정보의 유통과 표현의 자유를 제한할 수 있다. 이는 사적 존재인 포털을 검열의 주체로 재판부가 인정하는 것과 다를 바 없으며, 위헌적 요소를 포함하고 있다. 포털이 직접 관리하는 영역과 커뮤니티 관리자에게 위임된 카페와 게시판 등을 구분해서 작위의무를 판단할 필요가 있다. 단순 전달자 수준을 넘어서는 작위의무를 부과하기 위해서는 포털이 언론사로부터 제공받은 기사를 임의로 변경하거나, 내용 변경을 통해 명예훼손을 유도한 경우로 한정해야 한다. 더불어 포털이 언론사로부터 전재 받은 기사의 위법성을 알 수 있었고, 이를 삭제하지 않았다는 사실만으로는 공동정범이 성립될 수 없다. 결론적으로 전재 받은 기사를 적극적으로 변경하여 명백하게 명예훼손에 이르는 경우에 한해서 포털에 책임을 묻는 것이 '사적 검열의 강제'로부터 자유로울 수 있을 것이며, 온라인상에서의 표현의 자유가 보호될 수 있을 것이다.

Tunnel portals are often located in areas where the risk of rock fall and/or detachement of rock fragments from rocky slopes is high. In this case it is necessary to design the portals so as to protect the road (i.e. using an artificial tunnel) or to instal structures that are able to intercept falling blocks on the slope. This paper deals with the design problems of these structures and includes a special analysis of net fences which have undergone a remarkable technological improvement over recent years.

관절경 수술에 있어서 적절한 삽입구를 만드는 것은 수술에 있어서 가장 중요한 시작이며, 이후 수술의 진행 과정을 쉽고 원활하게 할 수 있느냐를 결정짓는 중요한 단계이다. 수술을 하고자 하는 견관절 내를 정확히 검사를 하고, 다음 삽입구를 만드는 데에도 영향을 미치며, 관절 내에서 기구를 조작하는 데에도 영향을 미친다. 정상 구조물 및 병리 해부학적인 지식과 삽입구(portal)에 대한 이해가 관절경 수술을 용이하게 하는데 필수적이다.

Media manipulation of breaking news through article selection, ranking and tweaking of social media data and comment streams is a growing concern for society. We argue that the combination of human and machine curation on media portals marks a new period for news media and journalism. Although intermediary platforms routinely claim that they are merely the neutral technological platform which facilitates news and information flows, rejecting any criticisms that they are operating as de facto media organisations; instead, we argue for an alternative, more active interpretation of their roles. In this article we provide a contemporary account of the South Korean ('Korean') online news media ecology as an exemplar of how contemporary media technologies, and in particular portals and algorithmic recommender systems, perform a powerful role in shaping the kind of news and information that citizens access. By highlighting the key stakeholders and their positions within the production, publication and distribution of news media, we argue that the overall impact of the major portal platforms of Naver and Kakao is far more consequential than simply providing an entertaining media diet for consumers. These portals are central in designing how and which news is sourced, produced and then accessed by Korean citizens. From a regulatory perspective the provision of news on the portals can be a somewhat ambiguous and moving target, subject to soft and harder regulatory measures. While we investigate a specific case study of the South Korean experience, we also trace out connections with the larger global media ecology. We have relied on policy documents, stakeholder interviews and portal user 'walk throughs' to understand the changing role of news and its surfacing on a distinctive breed of media platforms.

It is widely confirmed that online retailers can obtain crucial resources and greater growth potential by depending on the external web portal sites as it is explained in resource dependence theory. Nevertheless, recent studies show that the effect of dependence may not always be beneficial for firms and stress the importance of finding relevant contingent factors. In this study, we identify and suggest that firms' age and niche width strategy, whether generalist or specialist, are contributing factors on moderating the positive relationship between resource dependence and firm growth. To test our hypotheses based on the theory, we have collected monthly web traffic data of online retailers and portals from March 2000 and July 2008. The empirical results lend support to our theory of the firm age having a negative interaction effect on web traffic dependence. Moreover, results verified that positive effect of depending on the portals may become greater if the online retailer is a specialist in terms of niche width.

Purpose: The purpose of this study was to evaluate outcome of ankle arthroscopy with high anteromedial and anterolateral portals for osteochondral talar lesion. Materials and Methods: A prospective study was conducted between March 1992 and January 2000 by one surgeon. Total 48 patients who had osteochondral talar lesion were included. Using high anteromedial and anterolateral portals, arthroscopic treatment was performed. A functional evaluation was performed with the Karlsson scoring scale. Results: Of the 48 patients, 28 cases had anterolateral talar lesion and 18 cases had medial talar lesion and 2 cases had central lesion. The 42 cases(87.5 %) had trauma history. On Karlsson scoring scale, anterolateral talar lesion was better than medial talar lesion(p=0.035). Conclusion: Using high portals, we could get better visualization of talar dome and posterior chamber of ankle, and do some limited procedures without additional portals. Osteochondral lesions were treated successfully only when they were traumatically induced and localized without diffuse chondromalacia of talus and tibia.

Purpose: The purpose of this study was to evaluate prognostic factors of ankle arthroscopy and the effectiveness of high anteromedial and anterolateral portals in diagnosis and treatment for various disease entities. Materials and Methods: The results of ankle arthroscopy were evaluated between March 1992 and January 2000 by one surgeon. Total 169 patients who were followed for a minimum of 12 months, were included in this study. Using high anteromedial and high anterolateral portals, all procedures were done with accessory portals if necessary. A functional evaluation was performed using the Karlsson score and questionnaire subjectively. Results: Fifty-six synovial impingement, 48 osteochondral lesion on talus, 10 impingement exostosis, 8 loose body, 27 osteoarthritis and chondromalacia, 10 postfracture fibrosis, 3 lateral plica, and 1 pigmented villonodular synivitis(PVNS) among 169 patients were diagnosed. Patients with the former four groups had satisfactory results and the latter four groups had not. Remaining 6 patients underwent arthroscopic arthrodesis, and 5 had satisfactory results. Conclusion: Using high anteromedial and anterolateral portals, we could get better visualization of talar dome and posterior chamber of ankle. For better clinical results, in ankle arthroscopy, not only operative skill but also proper indications are important. In case of synovial impingement after trauma, arthroscopy should be considered within one year after initial trauma. There were little correlation between the radiographic findings and arthroscopic findings of articular cartilage in osteochondral lesion of talus, and it is better to determine treatment modality based on the arthroscopic or MRI findings. Osteochondral lesions were treated successfully only when they were traumatically induced and localized without diffuse chondromalacia of talus and tibia.

The study aimed to analyze the current situation of the electronic portal of the Northern Border University, in terms of content and components, the extent of quality of use, service assurance and integrity, linguistic coverage of objective content, in addition to assessing the efficiency of the Blackboard e-learning platform and measuring the degree of safety of the portal, in addition to measuring the extent of satisfaction, through a sample that included 135 faculty members, as the researcher was keen to apply the case study methodology with the use of the questionnaire as the main tool for measurement, and the study found that there is an average trend among faculty members in the degree of content for the components of the portal and electronic security While it rose to good use, and very good at using the Blackboard platform.
