Companies actively engage with the public through social media to enhance sales and promote brand awareness, which was further encouraged by the pandemic. However, previous studies tend to consider companies as a group of identical features. This study focuses on the differences between B2B and B2C companies' social media content strategy in relation to user engagement. This study categorized KOSPI 100 companies that manage Facebook corporate fan pages into B2B and B2C, and then analyzed the contents they posted from January 1 to December 31, 2020. The result showed that B2C companies tended to use videos over images, prefer hashtags, and comment its product name more often compared to B2B companies. B2B companies preferred images, used more hyperlinks, and mentioned its company name more often. In B2B companies, images and length of text had positive effects on user engagement, while hyperlink and URL had negative effects. B2C companies' text length had positive effect on user engagement. This study provides practical implications to PR practitioners for establishing a social media strategy which enhances user engagement.

We consider the fault hamiltonian properties of m ${\times}$ n meshes with two wraparound links on the first row and the last row, denoted by M$_2$(m,n), (m$\geq$2, n$\geq$3). M$_2$(m,n), which is bipartite, with a single faulty link has a fault-free path of length mn-l(mn-2) between arbitrary two nodes if they both belong to the different(same) partite set. Compared with the previous works of P$_{m}$ ${\times}$C$_{n}$ , it also has these hamiltonian properties. Our result show that two additional wraparound links are sufficient for an m${\times}$n mesh to have such properties rather than m wraparound links. Also, M$_2$(m,n) is a spanning subgraph of many interconnection networks such as multidimensional meshes, recursive circulants, hypercubes, double loop networks, and k-ary n-cubcs. Thus, our results can be applied to discover fault-hamiltonicity of such interconnection networks. By applying hamiltonian properties of M$_2$(m,n) to 3-dimensional meshes, recursive circulants, and hypercubes, we obtain fault hamiltonian properties of these networks.

It is difficult to figure out the specific contents of the buildings in the internet spatial area, since those data on the internet present only the location of buildings and the outlines of lands on which buildings are located, An experimental study for the view management of building information at internet urban spatial area was conducted on the Web-GIS based map using hyper map. With the building information on the 2-D map, modified from the previous numerical map and the regional building information and additional information, a new form of building through 3-D icons was shown on the internet spatial area. This study shows the Web-based building management system, which is designed to manage attribute data about hyper-linked buildings of 2.5-D icons and to reproduce visual building information by putting a variety of information into hyper-linked icons on the hyper map. This system not only complements the lack of consistency between real buildings and those on the map, but also provides users with more familiar urban space, so that everybody can utilize the building information as long as he has access to the internet.

Reading and writing in the past make noble significance in 'narration', in other words, in 'the creation of narration', through the process of 'recording'; but in the modern times, it engenders controversies over narration and linearity. In other words, reading/writing in digital era, is devalued as the simple arrangement of test or the connection of vast information without narration nor linearity. However, the reading/writing through text and hypertext reading is not the phenomenon which should be criticized because of the lack of narration or linearity-not only the lack of narration and linearity -, a process of social and cultural transition; it should be revalued as a result. The change of reading and writing methods will inevitably accompany the layers, status, significance and value of the contents; thus it makes more sense, when the reading and writing methods in digital contents are approached as new pop culture phenomenon. This is the "The prose of everyday life", based on pop culture and "The society of Conversation", based on communication; proposed 'Digitelling' ; this is the reason why we should pay attention to the digital contents, created infinitely by the citizens of the world, as new mass-culture phenomenon.

This paper implemented the web service that converts general web page to the web page using the speech recognition and the web service consumer that provides speech recognition service for the web page. This system has the web service consumer, the web service provider that converts the web page and the web service provider that provides speech recognition. The web service provider that converts the web page analyzes general web page by using the regular expression and converts it to the speech-recognition web page. The speech recognizer is the web service providers that implemented in the previous study. As a result of experiment, we show that this system changes web page by analyzing tags and extracts hyperlink.

Keyword matching technique which is used in most information retrieval systems is unfit for efficient processing of geometrically increasing information. The problem can be solved by using semantic information and an efficient method of semantic processing is introduced in this paper. The technique uses conceptual graph to represent the semantic information and apply it for information retrieval. The implemented system can perform exact matching and partial matching. Partial matching has two different types. One is syntactic partial matching and the other is semantic partial matching. The semantic semilaries are measured by the subclass relations in the ontology. The introduced technique can be used not only information retrieval but also in various applications such as an implementation of dynamic hyperlinks.

The SMIL(Synchronized Multimedia Integration Language) documents are represented as logical structure information, spatial layout structure information, temporal synchronization structure information and hyperlink structure information, according as the structural characteristics of SMIL documents based on XML. This paper proposes the effective modeling and query method for the multi -structure information of inherent SMIL documents. In particular, we present the object-oriented modeling by using UML class diagram in order to represent the objects classes for the structured information of SMIL documents, and the hierarchical structure and the relationships for the objects classes. In addition, the objects classes definition is specified in compliance with SQL3 for database standard language. We also propose the access method and the query representation for hierarchical structure in order to retrieve efficiently the structural objects of SMIL documents.

본 연구에서는 VRML(Virtual Reality Modeling Language)을 이용하여 월드 와이드 웹(World Wide Web; WWW) 상에서의 3차원 디렉토리 서비스인 "3D 한마당"을 구현하였다. 현재 WWW 상에서는 많은 2차원 디렉 토리 서비스가 존재하나 3차원검색 서비스에 비해 사용자를 위한 가상 현실감이 부족한 단점이 있다. 또한 3차원 검색 서비스는 그 잠재적 수요가 점차 증가함에도 불구하고 아직 적은 편이며, 또한 중오성이 차츰 커 지는 전자 상거래를 위해 특화된 디렉토리 서비스도 그 요구에 비해 많지 않다. 3차원으로 디렉토리 서비스의 기능을 수행할 수 있는 3D 한마당은 HTML(Hyper Text Markup Language)에 의해 기술되는 2차원 전자 거래용 디 렉토리 서비스인 "한마당"을 보조하기 위해 제작된 것으로, VRML 1.0 사양에 맞추어서 만들어졌다. 3D 한마당 을 위한 VRML 월드를 만들기 위해, Pentium PC에서 3-D MAX 소프트웨어로 각 구성 객체들을 저작한 후, 이를 조합하여 VRML 1.0 사양을 따라 월드로 변환하는 방법을 사용하였다. 이렇게 완성된 3D 한마당은 기존의 2차원 전자 거래용 디렉토리 서비스인 한마당에서 하이퍼링크로 바로 접근할 수 있으며, 또한 월드 안의 객체에서 그 객체에 대한 2차원 테이블로도 연결이 가능하게 하였다. 이러한 3차원 가상상점 디렉토리 서비스는 전자 거래에 특화된 특성 때문에 정해진 개수의 객체들만 요구되어 구현이 쉬운 이점이 있고, 보다 인간에게 자연스러운 인테 페이스로 정보 검색을 지원하게 해줄 수 있다.정보 검색을 지원하게 해줄 수 있다.

The present Web surroundings is composed of HTML(Hypertext Mark-up Language) and thereby users obtains web informations mainly in GUI(Graphical User Interface) environment by clicking mouse in order to keep up with hyperlinked informations. However it is very inconvenient to work in this environment comparing with easily accessed one in which human's voice is utilized for obtaining informations. Using VoiceXML, resulted from XML, for supplying the information through telephone on the basis of the contemporary matured technology of voice recognition/synthesis to work out the inconvenience problem, this paper presents the research results about VoiceXML Web Browser designed and implemented for realizing its technology.
