This study examined the structure of YouTube video network and the factors for the diffusion of Chinese creator's videos through the case of famous Chinese creator Fengtimo. There is few interest to the diffusion of Chinese contents among Korean researchers, while they have been studied the consumption of Hallyu(Korean wave) contents overseas. Using the data that YouTube Data API offers, this study analysed the video network that the comments of which are same users with NodeXL tools and the regression model with JASP tools. The study found that there are three groups of the YouTube channels of that network. They are domestic official accounts of Fengtimo, foreign officail accounts of Fengtimo and individual creators' accounts. The official accounts share the videos of Fengtimo's songs and entertainment contents for the fans, where the individual creators share their own meme videos(UGC). The significant factors for the diffusion in the YouTube video network are comments, likes, out-degree, dislikes, in-degree and betweenness centrality. There are significant difference between official channel and indivisual groups on the views. And degree and betweenness centrality have mediating effect. It is necessary to conduct more research on that subject with many other cases if we want to get to know the generalized explanation.

A library catalog is most important finding tool to a library collection. This tool should be so designed as to enable users to handle with ease and convenience. Library catalog use study is necessary in order to identify the demands made on the catalog by its actual users and to measure the adequacy with which the catalog is meeting these demands. Many major catalog use surveys were performed by means of questionnaire and interview, but these methods are so difficult and perverse that the results of catalog use studies might often be far from scientific precision. The aim of this paper is to seek the guidelines with which one might assist the catalogers in providing an effective library catalog for their patrons. In order to get the first-hand information an actual survey was undertaken on searching behavior at the catalog of Jeonbug National University Library from November 30 to December 5, 1981 and from May 17 to May 22, 1982. The results of the survey can be summarized as follows: 1. Most of the students (79.77%) use the library. 2. Most of the library patrons (74.52%) use the public catalog as the searching tool to the library collection. 3. 67.85% of the catalog users are interested in searching materials written in Korean, Japanese, and Chinese. 4. 72.86% of the catalog users are interested in searching known items at catalog. 5. In known item searching, 49.44% of the catalog users choose title entry. 6. 20.17% of the catalog users are interested subject searching at the catalog. 7. Reference card is not utilized in searching. 8. For the translated items users want double entries in both vernacular and Korean. 9. At current catalog description, author, title, call number, translator, publisher and joint author are useful entry. Edition, author's date of birth and death, illustrative, size of book and bibliographical notes are not much utilized. 10. 55.39% of the catalog user need systematic guidance on how to use the library catalog and collection.

The game industry is growing most rapidly for a last 10 years. However, these days korean online game is not developed in chinese market any more quickly because there must be many significant problems. One of the most important problems can be a misunderstanding a chinese online game user. For instance, the Game community system shows an important position to choose an online game of chinese users. In this paper, We choose a three kinds of online game community systems and make a comparative analysis. We can expect a certain way through this research because we can see that most succesful online games in chinese market have a more expandable community systems. In order to make a succesful game contents in foreign country's game market, we must understand foreign gamers what they like or dislike. We think a next research will be about a specific relation between a foreign gamer and culture.

Objectives : The Dongui Bogam in My Hand', which is an output of computerizing Donguibogam (Principles and Practice of Eastern Medicine), is an interim outcome of the research project led by the Korea Institute of Oriental Medicine. This study examined the process in which Donguibogam, a record in Chinese and a classic of Oriental medicine, expanded into a modern content. Methods : This study will classify the modernization of Donguibogam into three 'contents' that form Donguibogam, 'container' that will hold the contents, and 'community' that is the consumer of Donguibogam. Towards the end, this study will sketch out the status of computerizing Chinese records in Korea, and point out the reality faced by computerization of ancient documents on Oriental medicine as well as the direction for the future. Results : 'The Dongui Bogam in My Hand' has been downloaded more than 10,000 times for 4 months since it releases in August 2014, and is used for at least 6,000 times on average every month. This achievement can be due to the two following reasons. First, the application contains high-quality contents such as the original text of Donguibogam as well as Korean and English translations. Second, it satisfied the needs of Donguibogam users with (1) the Browse function that well displays the table of contents, (2) the Search function that separates the title from the main text, and (3) the Personalization function designed to link and share relevant knowledge. Conclusions : Computerization of Chinese records was triggered by the request of the academia, but it was accelerated after being selected as a public laboring project to overcome the IMF crisis. However, computerization of ancient documents is not a simple task but a field of study to modernize classical knowledge. The success or failure of computerization of Chinese records is determined by whether high-quality modern 'contents' are secured, whether the 'container' design adequately implements the search, browse and link functions, and how well it fulfills the needs of the consumer 'community'.

As the numbers of Internet users and the growth of education market along with the generalization of distance study increase, e-Learning industry in China is growing rapidly more than 20% each year. However, domestic e-Learning industry for entry to the Chinese market is showing inadequate result even though its potential growth in China and their scale of industry is near about 3 trillion won. A type of this industry is combined with Information Technology (IT) and education industry and their complex factors need to be considered because of the country's education policy and ICT infrastructure. In addition to these factors, sometimes main agents can be the government or a private organization and they form different circumstances each other. Therefore, it is required to have an in-depth study of the entering the Chinese market based on an accurate analysis for Chinese education and culture. In this research, it will focus on the current state of e-Learning market in Korea and China after studying the e-Learning system through the existing reference research. Moreover, this research will propose a method of the entry for the Chinese e-Leaning market through a case study from domestic and foreign companies.

This study aims to determine the effects of the experiences of ZEPETO platform users on their attitudes and purchase intentions. A survey on 10-20 Korean and Chinese virtual fashion consumers was conducted. Brand experiences were independent variables, and offline purchase was the dependent variable. The results showed that, first, among the four factors of the brand experience, Korea and China have the highest explanatory power. Second, the brand experience of Korean consumers significantly impacted their brand attitude. Additionally, cognitive and emotional experiences of the brand positively impacted their brand attitude. Third, the brand experience of Chinese consumers significantly affected their brand attitude, and among the sub-factors of brand experience, cognitive experience positively affected brand attitude. Fourth, the brand experience of Chinese consumers significantly influenced their offline purchase intention, and among the sub-factors of brand experience, cognitive experience positively influenced their offline purchase intention. Overall, an emotional branding strategy that provides brand and product information must be implemented for the Korean market encouraging consumers to develop a positive and emotional connection with the brand. The Chinese market would benefit from formulating a reliable branding strategy that easily provides a wide range of brand and product information focusing on cognitive experiences.

Group key agreement protocols allow a group of users, communicating over a public network, to establish a shared secret key to achieve a cryptographic goal. Protocols based on certificateless public key cryptography (CL-PKC) are preferred since CL-PKC does not need certificates to guarantee the authenticity of public keys and does not suffer from key escrow of identity-based cryptography. Most previous certificateless group key agreement protocols deploy signature schemes to achieve authentication and do not have constant rounds. No security model has been presented for group key agreement protocols based on CL-PKC. This paper presents a security model for a certificateless group key agreement protocol and proposes a constant-round group key agreement protocol based on CL-PKC. The proposed protocol does not involve any signature scheme, which increases the efficiency of the protocol. It is formally proven that the proposed protocol provides strong AKE-security and tolerates up to $n$-2 malicious insiders for weak MA-security. The protocol also resists key control attack under a weak corruption model.

In this paper we introduce a software package, the Very long baseline interferometry Network SIMulator (VNSIM), which provides an integrated platform assisting radio astronomers to design Very Long Baseline Interferometry (VLBI) experiments and evaluate the network performance, with a user-friendly interface. Though VNSIM is primarily motivated by the East Asia VLBI Network, it can also be used for other VLBI networks and generic interferometers. The software package not only integrates the functionality of plotting (u, v) coverage, scheduling the observation, and displaying the dirty and CLEAN images, but also adds new features including sensitivity calculations for a given VLBI network. VNSIM provides flexible interactions on both command line and graphical user interface and offers friendly support for log reports and database management. Multi-processing acceleration is also supported, enabling users to handle large survey data. To facilitate future developments and updates, all simulation functions are encapsulated in separate Python modules, allowing independent invoking and testing. In order to verify the performance of VNSIM, we performed simulations and compared the results with other simulation tools, showing good agreement.
