Ecological and ecosystem database is becoming very necessary to understand origins and relationship between human and nature and also to minimize disturbance caused by human activities. An ecological information portal can play important roles as a computing system to collect knowledge, distributed research findings and separated data from researchers. In this study, we designed and developed ecological information portal service (EcoBank 1.0) for collecting and providing ecological information for diverse classes of stakeholders. To reach the goal, we had reviewed related and comparable ecological database portals to design conceptual structure of EcoBank system including database management framework. Then, we developed some functions of ecosystem analysis for each stake-holders (researchers, general public and policy makers). As a result of this study, we successfully designed of EcoBank system covering the functions of Digital Object Identifier(DOI) publishing and data quality management process. Also, we (1) applied ecological indices for calculating biodiversity by administrative boundary for policy makers, (2) provided statistical information of econature map for general public and distribution characteristics of species for researchers. To make a successful establishment of EcoBank, we have to collect and build up related database and offer various and reliable ecological data consistently. We expect that the successful construction of EcoBank will help not only to accomplish sustainable development goals but also to raise the welfare of ecosystem in Korea.

When a competent employee leaves an organization, the technical skills and know-how possessed by that employee also disappear, which may lead to various problems, such as a decrease in organizational morale and technology leakage. To address such problems, it is important to increase employees' job satisfaction. Due to the advancement of both information and communication technology and social media, many former and current employees share information regarding companies in which they have worked or for which they currently work via job portal websites. In this study, a web crawl was used to collect reviews and job satisfaction ratings written by all and incumbent employees working in nine industries from Job Planet, a Korean job portal site. According to this analysis, regardless of the industry in question, organizational culture, welfare support, work system, growth capability and relationships had significant positive effects on job satisfaction, while time and attendance management, performance management, and organizational flexibility had significant negative effects on job satisfaction. With respect to the path difference between former and current employees, time and attendance management and organizational flexibility have greater negative effects on job satisfaction for current employees than for former employees. On the other hand, organizational culture, work system, and relationships had greater positive effects for current employees than for former employees.

The purpose of this study is to analyze science fields and content elements of the science reports in a web portal site of Republic of Korea in view of scientific literacy. The main results of the analysis on the 679 reports sampled in a year are as follows. First, 506 reports in 46 fields were identified. Reports about technology and earth science occupies 16% respectively, and life science occupies 13%, medical science 4%, chemistry, company, others 3% and physics 1%. Almost reports show technology as associate field. Second, the frequency rate of reports including scientific literacy content elements is 52%. Reports related to 'physics' and 'chemistry' as dominant fields show relatively high rate in scientific literacy elements. The element, 'social context' is included in about 96% of the reports. Both 'data and statistics' and 'application' show relatively low rate and large gaps according to dominant fields. A few concluding remarks and proposals follow from these results. First, as almost science reports show the nature of integrated science, scientific literacy acquisition through science reports in internet requires the integrated scientific view. Especially most science reports includes the contents related to technology or medical science, so the point of view in the science-technological literacy is required. Second, the scientific literacy content elements in reports show various rates according to dominant fields. Therefore, science reports need to complement the deficient content elements to carry out the role of science reports as scientific literacy sources.

인터넷 이용자들이 포털을 활용해 뉴스 콘텐츠를 소비하는 경우가 늘어나면서 포털이 뉴스의 연성화를 촉진해 여론형성에 문제가 있다는 비판을 받고 있다. 이러한 비판에 대응하기 위해 일부 포털은 기존의 뉴스배치모델과 달리 언론사로 직접 연결되는 뉴스캐스트 서비스를 실시하고 있다. 본 연구는 뉴스 배치모델과 뉴스캐스트 모델이 뉴스의 연성화와 의제설정에 차이를 보일 수 있는지 포털들 간의 비교를 통해 그 차이를 규명하고자 시도하고 있다. 구체적으로 '네이버', '다음', '네이트'의 3대 포털을 대상으로 특정 기간 동안 서비스되는 뉴스를 내용분석(Content Analysis)하였다. 이를 통해 포털의 뉴스 공급 모델이 가지는 특성과 연성화 정도를 평가하고 그 함의를 도출하고 있다. 연구결과 뉴스캐스트 모델의 실시 이후에도 포털의 연성화와 선정성은 크게 개선되지 못하고 있음이 밝혀졌다. 따라서 포털이 단순히 기사를 재매개하는 관점에서 벗어나 건전하고 질 좋은 뉴스 콘텐츠를 유통하는 방향으로 포털 저널리즘이 재정비되어야 할 것이다.

일반적으로 지진발생시 터널구조물은 지상구조물에 비해 입는 피해가 매우 작다고 해서 내진설계에 대한 인식이 부족하였다. 그러나, 현재까지 많은 유형의 지하터널이 건설되었고, 앞으로는 더 많은 건설계획이 있으므로 지진시 지하터널구조물에 대한 안정성 확보가 중요하고 많은 연구가 필요하다. 본 논문에서는 지진발생시 터널의 동적거동을 파악하고, 적절한 내진해석을 제안하기 위해서 응답변위법과 동적해석법을 이용하여 내진해석을 실시하였다. 해석 결과는 지진발생시 터널구조물이 지반의 변형에 순응한다는 것을 나타내었고, 응답변위법에 의한 내진해석이 동적해석법에 의한 것보다 대부분의 경우 더 보수적인 해석이라는 것을 보여주었으며, 마지막으로 동적해석시 간편화된 2차원유한요소해석이 복잡한 3차원해석보다 내진해석시 더 효율적이라는 것을 보여주었다. 갱구부의 내진해석결과에서는 지진파가 터널축과 평행하게 진행할 때 갱구부에 설치된 라이닝에 가장 큰 단면력이 발생하는 것으로 나타났다.
