This paper has analyzed how the format of the text page and the contents of space surrounding the text in the news stories of the portal sites are made-up. The result of analysis showed that the formats of the text page in Naver news story were more intricate than those of Daum, Nate and Yahoo. Also, Naver was higher in the number of advertising, the type of advertising, the entertainment contents, and various types of contents than other three portals. Especially, the percentage of new story related to entertainers was the highest. It was the portal site Daum that advertised the news story most of all in its text page. In contrast, it was portal site Yahoo that inserted the advertisements least of all. But from the whole sides, it was found that the formats and contents of the text page of the news story in these three portal sites have similarly been made-up. Consequently speaking, for the serviceability of use in news story, it can be evaluated that the news service method in portal sites is higher than that in press dot coms.

As concerns about users' privacy infringement on Online Behavioral Advertising(OBA) increase, regulators are taking measures such as drawing up guidelines for OBAs, and websites provide OBA guidance in compliance with such guidelines. As a result of reviewing the status of providing OBA guidance on websites, access to OBA guidance pages was rather complicated. In order to analyze the issue from the UI/UX perspective, following the "Guidelines for Privacy in Online Behavioral Advertising" applied to all types of OBA transmitted on websites, this study aims to structuralize a navigation of page movement from two starting points, 1) Main Page, 2) The page where OBA is delivered, to OBA guidance pages. Also, with understanding the problems found in the access and navigation of OBA guidance pages by analyzing features found during the page navigation, such as hyperlinks containing keywords, and movement pages.

Recently, with the development of technology, social network service (SNS) has become a hot topic. Lots of companies are now making online marketing strategy to promote their products and brand identities using SNS. Through these strategies, companies can produce more profit as well as make better brand images by performing online public relations. Among the SNSs, Facebook has a lot of users, it has been regarded by companies as a suitable platform with respect to online marketing for latent customers. The companies of today typically have at least one account and a Facebook page, and constantly make relationships with customers. However, companies have been thoughtless in this process, and usually provide information to customers through one-way communication. Based on this phenomenon, a study was conducted herein on how to use Facebook pages for promoting products and brand identities, keeping good relationships between companies and customers. This study assumed that the types of interaction on Facebook pages and user involvement are the key factors affecting decision making of purchase. Four types of Facebook pages which were made virtually were used in analysis with 56 participants who were selected for the experiment. The results indicated partial verification of the hypothesis. Particularly, product involvement had an effect on decision making of purchase in all conditions. According to these results, it can be explained that there are close relationships between the psychological status of online behaviors and Facebook corporate pages. In addition, through linear tendency of this phenomenon, this can infer how to setup a positive relationship with latent customers and make improve brand images of products.

To effectively investigate the identification and distribution of the lactic acid bacteria in Kimchi, polyphasic methods, including a PCR, SDS-PAGE of the whole-cell proteins, and 16S rRNA gene sequence analysis, were used. In various types of Kimchi fermented at 20$\^{C}$, the isolate KHU-31 was found to be the predominant lactic acid bacteria. This isolate was identified as Lactobacillus sake KHU-31, based on SDS-PAGE of the whole-cell proteins and a 165 rRNA gene sequence analysis, which provided accurate and specific results. Accordingly, the approach used in the current study demonstrated that Lactobacillus sake KHU-31, together with Leuconostoc mesenteroides, were the most predominant lactic acid bacteria in all types of Kimchi in the middle stage of fermentation at 20$\^{C}$.

The purpose of this research is to consider whether current science textbook is designed to let children properly obtain scientific knowledge through research study and at the same time provide an implication to help development of science textbook for the 2015 revised curriculum through comparing and analyzing of illustration in science textbooks of grade 5 and 6 published based on the 2007 curriculum and on the 2009 revised curriculum. The conclusion of comparison and analysis on illustration of the grade 5 and 6 science textbooks in the 2007 curriculum and the 2009 revised curriculum as follows. First, according to the comparison and analysis result on in the textbook, science textbook of year 2009 revised for grade 5 and 6 had 1.65 illustration per page and for the 2007 curriculum, it had 1.98 illustrations per page having 0.83 times more illustrations than that of the previous one. Second, the types of illustrations both textbooks had a higher ratio of pictures that are very detailed and objective which can identify scientific facts. In terms of role of illustration, illustrations providing various and realistic data related to the learning for students to have enough scientific experiences accounted for the most ratios.

Various types of digital displays from PC monitor up to smart watch have been developed in response to the dramatic technological progress of electronics. Accordingly, web content creators have the need to provide web contents respectively depending on the different display environments, which increases production time and costs. As a technique for overcoming this, the responsive web design method has been proposed, which means a web page with the size of the screen being adjusted depending on the types of display. Although the responsive web system is increasingly implemented in the region of contents search pages of domestic portals, there are still many cases that contents are implemented separately for PC and for mobile. In this paper, we investigate the responsive types of the web implementation of contents search pages of domestic portal, and propose an efficient new UI for responsive web to individual types of contents search pages which responsive design is not applied to.

This experiment was carried out to investigate some physico-chemical properties of myofibrillar proteins isolated from alkaline and acid rigor muscles of rabbit. The degree of fragmentation was about 0.35 at 3 days of postmortem in acid rigor muscle fiber, whereas it was only 0.3 at 7 days of postmortem in alkaline rigormuscle fiber. $Mg^{2+}$-activated ATPase activities of actomyosin were increased to the highest level at 1st day in acid rigor and at 3rd day in alkaline rigor muscle fiber. $Ca^{2+}$-activated ATPase activities of actomyosin were slightly increased at postmortem. $Mg^{2+}$-, and $Ca^{2+}$-activated ATPase activities were higher in alkaline rigor muscle than those in acid rigor muscle at postmortem. Solubility of actomyosin increased with postmortem but no differences were observed in rigor types. SDS-PAGE(sodium dodecyl sulfate polyacrylamide gel electrophoresis) band patterns of myofibrils did not show significant differences between rigor types, but newly 30.000 dalton proteins were appeared at 3 day postmortem in both rigor types.
