The object of study is to compare the response times between WiBro and wired internet in terms of users. We conducted experiments using six portal sites such as Naver, Daum, Google, Paran, Nate, and Yahoo. Because we could not receive all signal levels of WiBro at the same palace, we compared WiBro levels 1~3 and wired internet. We verified wired internet is significantly the fastest among wired internet and than WiBro levels 1~3. We could not find which level is the fastest among WiBro levels 1~3. On average, wired internet is faster than WiBro level 1, 2 and 3 about 5.05, 4.20, and 4.14 times, respectively. In addition to comparing WiBro levels 4~5 and wired internet, more researches on accelerating the response times are needed.

As the recent advances in network and wireless communications and semiconductor design and process technologies, our computing platform is rapidly shifting from desktop PCs to mobile devices such as UMPC (Ultra Mobile PC), Tablet PC, and Smartphone. Especially, wide-spreading Smartphones allow a new field of application based on location based services available with an user interface called augmented reality (AR). Therefore, this paper introduces an implementation of AR using various OpenAPls on Android Smartphones. In order to utilize enrich user data in real time, the system integrates with location based social network services also with OpenAPI. These APIs enable third-party developers to make use of rich contents of many portal web sites. The prototype was implemented on the real Android phone, Sky Sirius, and the result shows that it can provide an efficient location based service using AR technology without any constraints on mobile devices; in addition, it connects SNS to AR for sharing user data including photos, videos, and messages based on a specific location.

From the late 17th to the early 18th century, Europeans were strongly intrigued by products from the East. Therefore, several countries like England, France, and Netherlands formed the 'East India Company' to pursue trade. First, European markets rapidly responded to this desire for exoticism by importing goods; then, they produced imitation Oriental goods. Finally, they made stylistically advanced exotic merchandise from the perspectives of European. In terms of the textile industry, this trend was expressed in the pattern design of silk, or the so called 'bizarre silk.' In this paper, bizarre silk patterns were scrutinized based on a digital archive of museums, catalogues of museums, portal sites, and the literature. The bizarre silk patterns were analyzed then classified into six categories: pseudo-Oriental plant pattern, pattern mingled with architectural motifs, pattern of juxtaposed with Oriental goods, abstract pattern, exuberant pattern with metal threads, and semi-naturalistic pattern. These patterns were characterized according to the following features: strangely large exotic floral patterns were undulating and asymmetrical; exotic foliage and flowers were sometimes mixed with architectural motifs or Oriental goods to easily show the Oriental influence; motifs of bizarre silk patterns were abstractly stylized; bizarre silk patterns became luxurious once more like the Baroque period; finally, floral patterns became more natural, and still exotic motifs remained in the background to maintain the bizarre silk features. These bizarre silk patterns evolved from the viewpoints of Europeans through acceptance stage, compound stage, and confluent stage.

In 1996, GS E&C became the first in the industry to adopt a Project Management System using EVM(Earned Value Management) to link schedule with profit/loss. In 2006, the TPMS(Total Project Management System) was completed by adding the concept of Lean Construction and JIT(Just In Time) to the Project Management System. This was done with the purpose of reducing waste and creating optimal work processes. This has been implemented on all sites and has enabled drastic increase of productivity. The portal provides customized information to the client, inspector and subcontractor personnel. Since various parties are receiving information that suits their requirements and is easy to use, usage has increased and since they are on the same platform, quick decisions and information sharing is possible. The purpose of the PMIS's success model in construction projects, this paper tests and proves the TPMS's efficiency and productivity to Dongnam Distribution Complex project.

On Dec 1, 2008, according to the special law for the information disclosure of education relevant institutes, the educational information of each university is opened at their homepages and at portal web sites. Every university, thus, is in the moment to set up strategies to consistently respond to following information disclosure as well as the one already disclosed. The strategy should contain the assurance of the basic accountability mechanism of the university. On the occasion of the public announcement of the university information, the present study has a purpose to examine the structure of the university accountability and to suggest a mechanism, which is necessary for effectively and efficiently executing the increasing accountability practices in disclosing and announcing the information. To meet the purpose, this study introduces how to redesign university jobs as practices focused on evidence information for the accountability and also suggests solutions how to improve the mechanism for the accountability responsibility, which include clarifying the roles and responsibilities for accountability jobs, revising the process of information disclosure and building the information systems for an accountability.

The purpose of this study is to investigate science consumers' perceptions of the National Science Museum and suggest effective management strategies for the museum. Research questions were established and the analyses were conducted to achieve the research goals. The collection and analysis of the data were conducted through a new approach to image analysis that combines qualitative and quantitative methods. First, the image of the concept of science was derived from science consumers (adults, undergraduate and graduate students) through a qualitative research method (group-interviewing), and then text analysis was conducted. Second, quantitative research was conducted through LDA (Latent Dirichlet Allocation)-based topical modeling of 63,987 words extracted from 12,920 titles of blog postings from one of the most heavily-trafficked portal sites in Korea. The results of this study indicate that the perception of science differs according to the characteristics of the respondents. Further, topic-modeling extracted 20 topics from the blog posting titles and the topics were condensed into seven factors. Detailed discussions and managerial implications are provided in the conclusion section.

Recently, the influence of SNS and online media is rapidly growing with a consequent increase in the interest of marketing using these tools. Blog marketing can increase the ripple effect and information delivery in marketing at low cost by prioritizing keyword search results of influential portal sites. However, because of the tough competition to gain top ranking of search results of specific keywords, long-term and proactive efforts are needed. Therefore, we propose a new method that recommends associated keyword groups with the possibility of higher exposure of the blog. The proposed method first collects the documents of blog including search results of target keyword, and extracts and filters keyword with higher association considering the frequency and location information of the word. Next, each associated keyword is compared to target keyword, and then associated keyword group with the possibility of higher exposure is recommended considering the information such as their association, search amount of associated keyword per month, the number of blogs including in search result, and average writhing date of blogs. The experiment result shows that the proposed method recommends keyword group with higher association.
