It was analysed and considered about entry methods of headings in Japanese book cataloging which using methods of major universities and public libraries in our nation at present. I was suggested and clarified one's position that authors heading must make an entry to our pronunciation after translating from sound of chines letters, title headings must make an entry translation from Japanese title or Chinese title, to Korean. On the cataloging of authors heading or title heading, if cataloging make an entry to Japanese pronunciation it have many faults as follow. (1) In the title and authors heading of Japanese books, if it make an entry as Kana letter, not only non skilled librarian at Japanese language will have many faults but also non skilled users to Japanese language or pronunciation will very difficult to reference in title and authors catalog card. (2) If it Romanize the catalog card of title and authors heading in the Japanese books, librarian of the catalog part will make efforts and take pains to the catalog work. In addition, catalog users which is skilled in Japanese language but can not understand or unknown to the Romanized entry, and which if not understand to the, methods of entry will very difficult to card investigation or can not refer to catalog card. (3) If it make an entry to Korean in the authors and title heading from Japanese sound or pronunciation, librairans and library users which is unskilful as Japanese language will be inconvenience to works and investigation of library materials.

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.

Methods : Our study have been based on the following premises. 1. Using data obtained from literature contributes to accurate diagnosis 2. Displaying the data before users request contributes to accurate conclusion. Displaying before users request enable users to recognize their overlooking a fact on purpose or not. 3. Checking symptoms that are commonly accompanied with a group of diseases that accompany symptoms appealed by a patient contributes to accurate conclusion. These symptoms are worthy of checking. 4. Comparing more than two candidates contributes to accurate conclusion. Users can compare their accompanied symptoms with patients symptoms and this helps users to make a decision. Results : Based on the above premises, we have developed an literature based algorithm to provide various functions, such as recommending symptoms to check, comparing groups of symptoms, differential diagnosis, recommending medicinal materials to prescribe, and more. Conclusions : By the results of simulation with virtual diagnostic scenario, we concluded this algorithm is useful helping clinician in diagnosis procedure.

The growing popularity of mobile application has led to researchers and practitioners needing to understand users' mobile application download behaviors. Using large-scale transaction data obtained from a leading Korean telecommunications company, we empirically explore how application download rank, which appears to users when they decide to download a new application, affects their extended mobile application download. This terminology refers to downloading an additional application in the same category as those that they have already downloaded. We also consider IT characteristics, user characteristics, and application type that might be associated with the extended application download. The analysis generates the following result. Overall, a higher rank of a new application encourages the extended application download, but the linear relationship between the rank and the extended application download disappears when critical rank points are incorporated into the model. Further, no quadratic effect of rank is found in the extended application download. Based on the results, we suggest theoretical and managerial implications.

In this paper, the purpose is to verify the impact of performance expectations, effort expectations, social impact, individual innovation and perceived value on the intent of use and the behavior of use. Used Unified Theory of Acceptance and Use of Technology (UTAUT) to verify the applicability of this model in China, and established the research model by adding two new variables to UTAUT according to the situation of the Chinese market. To achieve this goal, 345 questionnaires were collected for experienced music creators using artificial intelligence nuggets in China by means of Internet research. The collected data were analyzed through frequency analysis, factor analysis, reliability analysis, and structural equation analysis through SPSS V. 22.0 and AMOS V 22.0. The verification of the hypotheses presented in the research model identified the decisive influence factors on the use of artificial intelligence music acceptance by Chinese users. The study is innovative in that it attempts to verify the applicability of UTAUT in the Chinese context. In the construction of the user acceptance model of AI music, three influencing factors will have an effect on users' intentions, and according to the degree of effect, from largest to smallest, they are respectively Perceived Innovativeness, Performance Expectancy and Effort Expectancy. This paper will also provide some management advices, i.e. improving the utility and usability of AI music, encouraging users with individual innovativeness, developing competitive and attractive pricing policies, increasing publicity, and prioritizing word-of-mouth advertising.

With the development and popularization of Internet, the competition of SNS market is now getting fiercer and fiercer. SNS service providers need to keep updating their service to sustain their customers' continuance use. However, due to the homogenization of functions and services from different applications provided by different developers, there comes a new phenomenon that users shift from one SNS to another SNS. In line with this, the current study aims to explore factors affecting switching intention among SNS users by applying migration theory which explains people's migration behavior from one place to another. Findings from surveys of Korean and Chinese college students suggest that there was a difference of factors influencing switching intention among the two countries. For Korean college students, alternative attraction was the strongest factor leading to SNS switching intention. On the other hand, peer pressure was the strongest factor leading to SNS switching intention among Chinese college students.
