Objectives: This study was performed to investigate the relationship between the incidence of national notifiable infectious diseases (NNIDs) and meteorological factors, air pollution levels, and hospital resources in Korea. Methods: We collected and stored 660 000 pieces of publicly available data associated with infectious diseases from public data portals and the Diseases Web Statistics System of Korea. We analyzed correlations between the monthly incidence of these diseases and monthly average temperatures and monthly average relative humidity, as well as vaccination rates, number of hospitals, and number of hospital beds by district in Seoul. Results: Of the 34 NNIDs, malaria showed the most significant correlation with temperature (r=0.949, p<0.01) and concentration of nitrogen dioxide (r=-0.884, p<0.01). We also found a strong correlation between the incidence of NNIDs and the number of hospital beds in 25 districts in Seoul (r=0.606, p<0.01). In particular, Geumcheon-gu was found to have the lowest incidence rate of NNIDs and the highest number of hospital beds per patient. Conclusions: In this study, we conducted a correlational analysis of public data from Korean government portals that can be used as parameters to forecast the spread of outbreaks.

As open data(public data) began to be recognized as a source of national economic development, many countries began to build public data portals and provide open data to the private sector. In accordance with this trend, open source communities have begun to develop open data platform such as CKAN and enable to share dataset among open data platforms by applying metadata standard technology. However, many governments and local governments are still making it difficult to share data between data portals because they build their own platforms. In this paper, we propose a DCAT-based metadata transformation tool to solve these problems, and show how to transform a dataset into DCAT.

Background: Arthroscopic exploration of ventromedial part of canine coxofemoral joint is limited in conventional dorsal approach. Objectives: We evaluated the efficacy of a medial arthroscopic approach to the coxofemoral joint of dogs by analyzing the joint visible area and performing a safety analysis. Methods: Arthroscopic approaches to the coxofemoral joint were made in five cadavers using a traditional (dorsal) and novel (medial) approach. Three observers scored the visible area of images and videos of the acetabulum and femur. A safety analysis was performed via dissection of the medial hind limb. The distance between neurovascular structures and arthroscopic portals was measured. Results: The acetabulum was more visible in the dorsal than in the medial approach, with mean visualization scores of 16 ± 0.00 and 11.83 ± 1.26, respectively. The medioventral side of the femur was significantly more visible in the medial than in the dorsal approach, with mean visualization scores of 3.9 ± 0.99 and 6.93 ± 0.58, respectively. Safety analysis confirmed the medial portal site was safe, provided that the surgeon has comprehensive knowledge of the joint. The minimum distance from the arthroscopic medial portals to the nearest neurovascular structures was 2.5 mm. Conclusions: A medial arthroscopic approach to the canine coxofemoral joint has potential clinical application. Dorsal and medial approaches differ significantly and have distinct purposes. The medial approach is useful to access the ventromedial joint, making it an eligible diagnostic method for an arthroscopic evaluation of this area.

Computational grids are emerging as a new infrastructure for internet-based parallel and distributed computing. Grid systems are enables the sharing, exchanging, discovery and aggregation of resources which distributed multiple administrative domains, organizations and enterprises. Accounting information service is one of the main obstacles to widespread adoption of the grid. But, most of grid portals do not support accounting information service. In this paper, we design an accounting information service and build a web-based grid portal including account management service and accounting information service.

1931년 Burman은 주관절의 제한된 관절 공간, 관절낭 팽창의 어려움, 삽입구 주변에 근접한 신경-혈관 구조물에 의해 주관절 관절경은 불가능하다고 보고하였다. 비록 1935년 자신이 다시 여러 번 시도 끝에 주관절 전방 관절낭을 관절경으로 관찰한 후 주관절도 관절경적 접근이 가능하다는 점을 처음으로 언급하였지만 1980년대 중반까지도 몇몇의 보고를 제외하고 주관절 관절경에 대한 관심은 매우 적었다. 그 후 주관절 관절경은 관절경 기구들의 발달과 소관절을 위한 소구경 관절경의 발전과 함께 하였다. 1985 Andrew와 Carson이 supine position에서 전외측, 전내측 그리고 후외측 삽입구를 이용하여 주관절을 관찰하였으며 1989년 Poehling은 후방 주관절 접근이 용이하도록 prone position으로 관절경을 시행하였고 최근 새로운 접근 방법 및 확대된 적응증에 대한 보고가 점점 늘어나고 있다. 주관절 관절경의 합병증은 적지만 주관절 주변의 해부학적 구조물에 대한 정확한 이해를 가지고 있어야 심각한 합병증을 발생을 예방할 수 있다.

Recently, there has been growing interest in public participation GIS (Geographic Information System) technology that enables spontaneous public response to increasingly frequent flood and drought events. Accordingly, social and economic demands are increasing on portal services that are designed to help cope with natural hazards such as earthquakes. By focusing on a specific hazard, urban flood, this study designed a prototype of a disaster response portal and its service system. The community map developed in this study is focused on prevention and mitigation of the urban flood damage by analyzing the vulnerable areas, and providing effective means to inspect the roads and sewer systems. By considering the compatibility with VGI (Volunteered Geographic Information) portals, the study created a system environment by employing universally used open-source software programs such as Apache Tomcat, GeoServer, GeoNetwork, and PostgreSQL/PostGIS.

Information technology has been transforming the relationship between shippers and carriers, but an unresolved question remains: what is the relative importance to shippers of service versus cost benefits of e-logistics solutions? This research develops and empirically tests a model to determine how Internet-based logistical operations in international shipping impact on the relative importance of cost versus service benefits to shippers. Contrary to expectations, results show that shippers perceived cost benefits from well-designed web sites, undoubtedly a consequence of perceptions that multi-function portals with ease of access contributed to savings in time and money. Another result was the confirmation of the positive effects of cargo tracing and bill of lading issuance on service-related factors. Finally, this study draws attention to the need for improvements in on-line booking capabilities and development of a comprehensive common portal; issues that must be addressed for shipping lines to succeed in an increasingly competitive e-logistics market.

News contents, produced for paper readers, are more and more being used online instead of offline. Internet sites, expecially portals(naver, daum, nate etc.) are dominant marketplaces, where news are exchanged and values are added. So, establishing a new online news service system, which can satisfy news provider(copyright owner) and internet service provider together, is a necessary task under current online-dominant news service environment. UCI(Universal & Ubiquitous Content Identifier) and IPTC NewsML(News Mark-up Language) are considered as useful standards to compromise protection of news-copyright and enhancement of online use of news contents. This study is based on a real case of 'NewsBank' in korea, We expect that this study can show an inspiration to obtain two contradictory goals of copyright protection and free online use of copyright.

There is an increasing need to use mobile Internet as a research tool as wireless technology has been developing rapidly. However, little research has been conducted to confirm methodological validity of mobile Internet survey. This study examines the possibility of using mobile Internet as a survey tool by comparing survey results of mobile and stationary Internet surveys with the same questionnaire. The results were analyzed from both economic and theoretical perspectives. Both mobile and stationary Internet survey sites were implemented with supports from domestic mobile and stationary Internet portals and telecommunication companies. The results show that there exist several differences between two survey methods. First, many respondents who use mobile Internet gave up at the early stage. However, once people continued to respond, they answered the questions to the end. Second, means and standard deviations of mobile internet respondents were higher than that of stationary Internet. Third, the results of two survey methods were significantly different by comparing construct validity that includes both discriminant validity and convergent validity. Finally, this paper ends with implications and limitations of using mobile Internet as a survey tool.
