The rapid popularity of government social media has generated huge amounts of text data, and the analysis of these data has gradually become the focus of digital government research. This study uses Python language to analyze the big data of the Chinese provincial government Weibo. First, this study uses a web crawler approach to collect and statistically describe over 360,000 data from 31 provincial government microblogs in China, covering the period from January 2018 to April 2022. Second, a word separation engine is constructed and these text data are analyzed using word cloud word frequencies as well as semantic relationships. Finally, the text data were analyzed for sentiment using natural language processing methods, and the text topics were studied using LDA algorithm. The results of this study show that, first, the number and scale of posts on the Chinese government Weibo have grown rapidly. Second, government Weibo has certain social attributes, and the epidemics, people's livelihood, and services have become the focus of government Weibo. Third, the contents of government Weibo account for more than 30% of negative sentiments. The classified topics show that the epidemics and epidemic prevention and control overshadowed the other topics, which inhibits the diversification of government Weibo.

This study developed seven assumptions to demonstrate the effect of personal innovation, social influences, service quality, mobility and accessibility on perceived usability, perceived convenience use and use intention using a technology acceptance model developed by Davis(1989), and the results are presented as follows: First, the assumption that personal innovation and service quality of mobile banking service will influence the perceived usability was adopted while the assumption that social influences will affect the perceived usability was rejected. Second, the assumption that mobility and accessibility of mobile banking services will influence the perceived convenient use was selected. Third, the assumption that the perceived usability of mobile banking service will influence use intention was rejected while the assumption that the convenient use will influence use intention was adopted. This study suggests that as personal innovation, service quality, mobility and accessibility have a significant influence on use of mobile banking, service providers should pay more attention to development of security programs and diversification of contents.

The Han Dynasty was the great unification dynasty in history after the Qin Dynasty. Since the Han Dynasty inherited the Qin system, the seal script of the Han Dynasty developed continuously based on inheriting the Qin Small Seal Script. With the progress of social productivity, the Official Script gradually replaced the Seal Script in the Han Dynasty, but the Seal Script did not disappear completely; instead, a special line of development arose under the influence of the Official Script. Through the study of seal script of Han Dynasty inscriptions, this paper understands that the practical function of seal script of inscriptions has been weakening under the influence of clerical script, but the aesthetic value has been increasing day by day. Moreover, there were new artistic innovations in the context of the development of the diversification of inscriptional forms, and its emphasis on social role, cultural status, and the presentation of an aesthetic style that had a profound impact on later generations are worth studying.

This study explores the trends and implications of social welfare qualitative research in Korea. The results are follows. At present, social welfare qualitative research is entering in the quickening period. The characteristics of configuration of social welfare qualitative research in Korea are overwhelming inferiority in post-positivism and heuristics, wide differences between universities in metropolitan area and in local area at the aspect of amounts of qualitative research products, rapid increase in the interests of qualitative research in doctoral candidates, and distinguishment of doctoral candidates as a leader group in qualitative research. The results of critics of qualitative researches are follow: 1) initiative of naturalistic interpretism 2) inclination of methodicism 3) poorness of critical themes 4) propensity in grounded theory. These trends of social welfare qualitative research in Korea, in spite of the limits, have various implications: 1) Trying to critics of social welfare knowledge based on positivism and formation of opposing discourse to positivism 2) diversification in paradigm of inquiry 3) spread of narrative thinking of social welfare phenomenon.

With the rapid development of Social Network Service and with the diversification of user needs, new types of image-based SNS have emerged. Image-based SNS provides customized service to meet users' specified contents needs that have yet to be satisfied in conventional relation-based SNS like Facebook, leading the trend of service diversification. Unlike text-based SNS that has inconvenient view on a small mobile screen, image-based SNS provides the communication way focused on simple text message and image, and thus the main users of the image-based SNS are young people in their 20s who get accustomed to images, rather than text messages. Accordingly, the functions and roles of SNS UI have varied, and usability has been more important. With the users in their 20s who use image-based SNS, this study tried to look into the usability of the image-based SNS. To do that, heuristic evaluation method was applied to find UI problems. The main factors constituting usability were extracted, and user evaluation method was redesigned. Aside from the satisfaction measurement, this study conducted and analyzed a questionnaire survey with users in their 20s who used actual image-based SNS. This study analyzed usability factors that influenced of image-based SNS users. The analysis results are considered to be used as a fundamental material to improve usability in the process of developing social media service.

The advancements in scientific technology and information network in the 21st century allow us to easily acquire a desired knowledge. In the midst of today's informatization, globalization, and cultural diversification, adolescents experience emotional confusion while accommodating diverse cultures and information. This study aimed at examining three aspects of character suggested by the Ministry of Education, which are ethics, sociality, and emotion, and the actual sub-factors required for character education. To that end, a survey was conducted with adolescents who were at a character-building age, and social network analysis (SNA) was performed to determine the effect of character education on the sub-factors. The statistics program SPSS was used to investigate the general traits of the subjects and the validity of the research variables. The 2-mode data that were finally selected were converted to 2-mode data using NetMinder 4, which is a network analysis tool. Furthermore, a data network was established based on a quasi-network that represents the relationships between ethics, sociality, and emotion. The results of this study showed that the subjects considered honesty and justice to be the sub-domains of the ethics domain. In addition, they identified sympathy, communication, consideration for others, and cooperation as the sub-domains of the sociality domain. Finally, they believed that self-understanding and self-control were the sub-domains of the emotion domain.

The aim of this review is to show the evolution of the dairy goat sector in Europe from all perspectives. Starting from the current situation, the challenges and future potential of this livestock system are presented, as well as strategies to overcome the difficulties faced. Europe holds 1.9% of the world goat population and produces 15.1% of goat milk recorded worldwide. The goat species plays a fundamental economic, social and environmental role in many regions of Europe. The wide diversity of production systems and autochthonous breeds makes the sector very heterogeneous. In order to improve viability, a number of strategies need to be adopted to solve the current problems such as a low profitability, absence of generational change and a little or no recognition of the social and environmental role of the sector. Some strategies to improve the situation of the European goat sector include: i) generating market value that will recognise the diversity of the dairy goat sector (breeds, feeding models, derived products${\ldots}$); ii) promoting and raising awareness of the functional attributes of goat milk and derived products so as to increase consumption; iii) assigning an economic value to environmental and social functions; iv) improving working conditions through technological innovation to make goat farming more attractive to young people; and v) processing more milk into cheese or other dairy products in production areas.

Although social media is recognized as a Web service that allows people to share and utilize their own opinion, experience and information, it is also faced with some problems such as indiscreet information creation and sharing, which resulted in the decline of reliability of information. This research statistically analyzed the effect of social media on information sharing. As a result, social media is an efficient information tool that can support information sharing and allow people to get feedback from other people. It also brought a positive effect on the entire information behavior. In contrast, it still has weaknesses in the utilization of information, including the decline of information reliability and excessive creation of inaccurate information. Eventually, social media is an information tool that can support the diversification of information and also incurs the decline of reliability of information.
