Since a social networking service (SNS) isconsidered as an effective means to communicate and interact with customers, companies are trying to utilize SNS effectively. There is a lack of theory relating to the attributes of SNS. This study aims to investigate the attributes of SNS to classify SNS. Based on the social network theory, and previous studies on internet, blog, homepage, communication attributes, this study proposes the seven attributes to classify SNS: interaction, communication, entertainment, information, sharing, intimacy and connection. A pre-test, a pilot test and a main test are conducted. In the main test, 239 SNS users are participated. Through a factor analysis this study verifies the seven attributes of SNS. An analysis of variance with multiple comparisons of $Scheff{\acute{e}}$ method identifies that three attributes, interaction, communication and connection, are found to play significant roles to differentiate SNS. Looking at the overall mean values of the SNS by attribute, interaction, sharing, entertainment, intimacy and communication were relatively high in Facebook. Facebook showed higher values in attributes of interaction, sharing, entertainment, intimacy and communication. Twitter shows the relatively high scores for information and connection. Regarding interaction, Facebook shows higher scores than Twitter and Cyworld. For connection, Cyworld showed a significantly lower score than Twitter and Facebook. Cyworld was separated from the others in the light of communication. Cyworld is relatively weak in communication as it is limited to the message exchanges. The results will help in identifying major attributes for each SNS and classifying SNS.

The purpose of this study was to investigate the gender difference in adolescent's problem behavior and depression, and The main aim of this study was to develop a fundamental web design to provide information content that would be easy for average consumers to understand based on the classification of information related to food safety. Based on the information obtained through in-depth interviews, the researchers developed an information classification system that meets the needs of consumers, and which serve as a basic framework for a homepage for a food safety information center. A total of 62 food items in 6 areas were selected based on reports of food safety related events occurring between 1998-2009 (KFDA 2008). The classification system of risk factors such as chemical risk factors and biological risk factors were categorized. The specific features of the information content for individual food items provided for classification based on evaluation by professional food scientists and the importance of risk factors. By providing a consumer participation section and company participation section, it was anticipated that the food safety information center would be able to act as a moderator for food safety information communication among consumers, the food industry, and the government. Based on the development of a classification system and framework, a design plan and tree-map for the internet site was developed.

bone grafting is indicated in the case of bony defects and is classified into autograft, allograft, and xenograft. Synthetic bone graft is contrasted with these three categories in that it has a different donor source. Autograft is most prominent as it is known as a gold standard of all grafting procedures. Its principles and practices are well established via accumulated informations and clinical experiences, which imposes no regulations or restrictions in its clinical use. On the other hand, other bone graft procedures are under tight control for the safety and effectiveness of each product. Food and Drug Administration of the United States has a system in which the information on the approvals and clearances of bone graft materials on their internet homepage. All the bone graft materials that are under the regulations of the United States are classified into the category of medical devices, which includes allogenic bone, xenogenic bone, and synthetic bone graft materials. Each bone graft material has its own indication and the FDA approvals and clearances of medical devices contain the item of "intended use" to specify the indications of each bone graft materials. US dentists, as users of the specific bone graft materials, are provided with adequate information on the approved materials they are to utilize. As an user of these materials, Korean dentists are less provided with the information on the bone graft materials they want to use. Medical providers of the bone graft materials have to be able to provide their users with the essential information such as the intended use of the regulatory approval. Dentists must also be active in gathering informations on the material of their interest, and the system must be built in which both of the medical providers and users of bone graft materials can be satisfied in providing and getting the information, respectively.

This study proposed a method to classify internet websites based on occurrence frequency of medical terms in the webpages and website structure composed with webpages and hyperlinks. The classification was done by using the suitability measure defined by three factors: (1)occurrence frequency of medical terms in the whole terms involved in a webpage, (2)occurrence frequency of medical terms in de-duplicated terms involved in the webpage, and (3)the number of hyperlinks to reach to a specific webpage from homepage. We conducted an experiment to verify the proposed method with the 80 websites registered in directories related to medical field and 127 websites in nonmedical field directories, and the experiment result showed 82.5 % of accuracy of the classification.

Das Ziel dieser Arbeit liegt darin, den Bestand der wissenschaftlichen Web-Publikationen in der deutschen Linguistik darzustellen. Das Internet bietet heute $f\"{u}r$ die Forschung bereits zwei der wichtigsten produktiven $M\"{o}glichkeiten;n\"{a}mlich$ Information und Kommunikation. Akademische Kreise haben diverse Homepages entwickelt. Der schnelle Zugang zu aktuellen bibliographischen Daten und Forschungsergebnissen hat $f\"{u}r$ koreanische Germanisten einen besonders hohen Stellenwert. Wissenschaftliches Publizieren in Form von Fachzeitschriften ist ein gutes Modell $daf\"{u}r$. Fachzeitschriften erscheinen weltweit und relativ schnell, erreichen aber nur geringe Auflagen. Der Leserkreis ist fast identisch mit der Gruppe der potentiellen Autoren und Herausgeber. Ein Vorteil des elektronischen Publizierens ist die M\"{o}glichkeit$ multimeiale Dokumente und $weiterf\"{u}hrende$ Hyperlinks zu integrieren. Aber die $Qualit\"{a}t\;der\;Aufs\"{a}tze$ kann man kaum objektiv ermitteln und nur schwer beurteilen. Elektronische Zeitschriften $k\"{o}nnen$ sich in der Wissenschaft nur dann etablieren, wenn es gelingt, als wissenschaftliche Arbeiten von den wissenschaftlichen Kreisen oder von der Univerwaltung anerkannt zu werden. Folgende on-line wissenschaftliche Fachzeitschriften werden hier dargestellt; Linguistik online(ISSN 1615-3014), The Web Journal of Modern Language Linguistics(ISSN 1461-4499), PhiN(ISSN 1433-7177), Zeitschrift $f\"{u}r$ interkulturellen Fremdsprachenunterricht(ISSN: 1205-6545), und Language Learning & Technology(ISSN 1094-3501). 1)http://viadrina.euv-frankfurt-o.de/$\~wjoumal/deutsch/$ 2)http://wjmll.ncl.ac.uk/ 3)http://www.fu-berlin.de/phin/ 4)http://www.ualberta.ca/$\~german/ejoumal/$ 5)http://llt.msu.edu/ In der folgenden Homepage kann man auch eine Quellensammlung zu 'Dissertationen Online' finden. 6) http://www.educat.hu-berlin.de/$diss\_online/biblio.html$ Eine individuelle und institutionelle Offenheit und eine $n\"{u}chteme$ Anwendung der Materialien sind bei der Herstellung und Nutzung von Forschungsergebnissen erforderlich.

This paper presents an investigation into Cheollik based on 288 records about it at the homepage of The Annals of the Joseon Dynasty on the Internet. Cheollik was called in diverse names and worn by various social classes from kings to common people, but it was solidified as clothes for military officers toward the latter half of Joseon. Not only did it serve the purpose of clothes, but it also was used for a royal grant, diplomacy, shrouding a corpse, and royal coffin. It served the diplomatic purposes a lot especially during the reign of King Sejo and King Seongjong. Cheollik was usually made of cotton, hemp, silk, and mixed fabric with silk used most. Its major colors include white, green, red, blue, black, purple, grey, and yellow with white used most. The fabrics and colors of Cheollik became simplified toward the latter half of Joseon. Silk was most used in Cheollik for a royal grant, shrouding a corpse, and royal coffin. White was most used in Cheollik for kings' visit to royal tombs or their participation in ancestral rites. There were limitations with the selection of materials according to the social status and situations. It was stipulated that only Sa and Ju were used to make Cheollik for Dangsangguan and Danghaguan. Cheollik made of silk was banned for country residents and merchants. The color of Cheollik for Danghaguan was changed to blue and then red. Of military officers, only those who had a Gonsu title or higher were allowed to wear Cheollik made of silk in various colors. In the end, Cheollik was abolished for its low convenience and efficiency during the rule of King Gojong.

The purpose of this study is to investigate how to make a proper investment in ICO in the market. Previously, companies used to borrow money from banks or to obtain investments from venture capital (VC) and angel investors, but now ICOs are used as a new type of funding and financing model. The ICO sells the tokens or coins created on the blockchain openly online to raise the necessary funds, and provides the market value by paying the tokens or coins as much as the investment amount. According to this study, the limitations of the ICO market are (1) difficulties in evaluating the company, (2) uncertainties in investments, (3) lack of legal safeguards, and (4) measures to secure corporate stability after recruitment. At present, there is no way to cope with this systematically since the ICO is not protected in the legal framework. Nevertheless, we investigated the ways to make proper investment in the existing ICO market. In investing in ICO, investors should (1) consider investment methods and profitability, and (2) verify and judge investment fraud through various channels (ex. Homepage, composition team profile, etc.) and make investments based on this. This study will contribute to the formation of a healthy ICO market by understanding the newly emerged ICO market and studying the considerations when investing in it, thereby contributing to the right investor training and reducing the mass production of consumer damages caused by fraud. The limitation of this study is that the domestic ICO has not yet been examined in the legal framework, so further research is needed when policy changes occur in the future.
