Research on the establishment of new governance aimed at efficient policy planning and the implementation thereof by the government has been conducted in response to social changes. Nonetheless, governance is comprehensive and encompasses different meanings; it takes various forms in the process of its actual application. Therefore, systematic classification of research on governance and analysis on its research trend are required. Accordingly, three researchers who majored in policy sciences, business informatics, and library and information science, respectively, searched for theses related to governance published since 2016 from Research Information Sharing Service and conducted a social network analysis (SNA) on them. According to their research results, the main research topics were largely classified into collaborative governance and local governance. Keywords throughout the topics included network, participation, conflict, and trust in line with the characteristics of governance. Representative subjects of governance included education, urban regeneration, and the environment. Further, measurement of betweenness centrality showed local governance was a main topic for convergent research. This study will lead to a greater understanding of research on governance and help activate such research. One limitation of this study is that it analyzed only theses with the keywords but not all theses on governance. Follow-up research should analyze all theses on governance and statistically verify them with SNA indexes.

In this Study, Social Network Analysis of IoT related patents in South Korea, China, and Japan was conducted from the viewpoint of patent informatics. To this end, 2,526 patents filed by PCT until December 2019 were investigated up to the subclass level of the IPC code. As a result, in the case of South Korea, representative IPC codes are in the order of G06Q, H04L, G06F, H04W, and the highest frequency of interconnection is H04L→H04W, H04W→H04L, H04W→H04B. In China, the representative IPC codes are in the order of H04L, H04W, G05B, G06Q. South Korea has strong technological convergence centered on the G06Q, while China has strong convergence centered around H04L and H04W. Moreover, in China, H04L and H04W have more diverse combinations than in South Korea in Section A, B, G, and H. In the future, it is necessary to study the diversity of technology convergence of H04L and H04W in China.

The COVID-19 pandemic has affected many aspects of human life. The pandemic not only caused millions of fatalities and problems but also changed public sentiment and behavior. Owing to the magnitude of this pandemic, governments worldwide adopted full lockdown measures that attracted much discussion on social media platforms. To investigate the effects of these lockdown measures, this study performed sentiment analysis and latent Dirichlet allocation topic modeling on textual data from Twitter published during the three lockdown waves in Malaysia between 2020 and 2021. Three lockdown measures were identified, the related data for the first two weeks of each lockdown were collected and analysed to understand the public sentiment. The changes between these lockdowns were identified, and the latent topics were highlighted. Most of the public sentiment focused on the first lockdown as reflected in the large number of latent topics generated during this period. The overall sentiment for each lockdown was mostly positive, followed by neutral and then negative. Topic modelling results identified staying at home, quarantine and lockdown as the main aspects of discussion for the first lockdown, whilst importance of health measures and government efforts were the main aspects for the second and third lockdowns. Governments may utilise these findings to understand public sentiment and to formulate precautionary measures that can assure the safety of their citizens and tend to their most pressing problems. These results also highlight the importance of positive messaging during difficult times, establishing digital interventions and formulating new policies to improve the reaction of the public to emergency situations.

The objective of this research is to compare the teacher education system in countries that have reformed, or are in the process of reforming, their informatics education by reflecting ongoing social changes and developments in IT. The teacher education systems in Finland, Germany, Japan, the UK and US were compared. As a result of the study it was found that (1) the results did not differ according to the teacher education institution, (2) there was a focus on a minor subject, and (3) there were various routes for teacher training. The systems for special graduate schools were found to be developed, probation period after graduation was more than one year, and license renewal systems were being enforced. Based on these results, it was proposed that (1) more teachers be recruited to attend graduate schools and (2) that software training be given to all teachers as a minor. Finally, a license renewal system for revaluating teachers' qualifications was also proposed. This research is meaningful in that it compared the teacher training system in Korea with five major developed countries.

There are tries to unite through consilience in many fields. Interdisciplinary research is an instance of those. Linguistic studies called linguistic informatics or quantitative linguistics is a field of interdisciplinary research related with statistics linguists have studied chiefly statistics and linguistics. In the statistical aspect, there is need to supplement somewhat of the result of researches by linguists. This study shows statistical method can supplement insufficient objectivity in linguistic studies, and examines the way to raise a degree of completion of interdisciplinary research on statistics and linguistics. This study also shows an introduction and application of the statistical method can be useful for the deduction of objective linguistic information in linguistic studies.

This paper explains that socio-cultural contexts affect the transition in scholarly communication. Observing the process of introducing the open access model to the field of medicine in Korea, this paper found that the first, associations of medical societies considered a quality control system very important in the construction of an open access based fulltext DB, the second, there was an medical journal DB with a quality control procedure, and the third, many medical societies provided their journals fulltext to the public on their homepages. Consequently, this paper found that these factors had an effect on the process of transition in scholarly communication in the field of medicine in Korea.

Food and agricultural production sector, especially livestock production is vital for Mongolia's economic and social development. Domestic sheep play key roles for Mongolians, providing food (meat, milk) and raw materials (wool, sheepskin), but genetic diversity, origin of sheep populations in Mongolia have not been well studied. Studies of population genetic diversity is important research field in conservation and restoration of animal breeds and genetic resources. Therefore, this study aimed to investigate genetic characteristics and estimate origin through the analysis of mitochondrial DNA control region D-loop and Cytochrome b of Mongolian indigenous sheep (Mongolian native, Orkhon and Altanbulag) and one Europe sheep (Suffolk). As a result of there were found, 220 SNPs (Single nucleotide polymorphism) in the D-loop region, 28 SNPs in the Cytochrome B region, furthermore, 77 Haplotypes. The nucleotide diversity was only found in D-loop region (n = 0.0184). Phylogenetic analysis showed that 3 (A, B, and C) of 5 haplogroups of sheep have been identified in our research. Haplogroup C was only found in Mongolian indigenous sheep. Haplogroup D and E were not observed. As a result of haplogroups, haplogroup A was dominant (n = 46 of 94 sheeps), followed by haplogroup B (n = 36) and haplogroup C (n = 12). Sequence analysis showed that T deletion, insertion and heteroplasmy in D-loop region occurred at a high rate in Mongolian indigenous sheep population (T insertion = 47, T deletion = 83). The heteroplasmy, which has never been found in Mongolian sheep, has been newly discovered in this study. As a result, the Mongolian sheep varieties, which mainly derived from Asia, were in hybridization with European sheep varieties.

As a large amount of graph-structured data is widely used in various applications such as social networks, semantic web, and bio-informatics, keyword-based search over graph data has been getting a lot of attention. In this paper, we propose an efficient method for keyword search over graph data to find a set of top-k answers that are relevant as well as non-redundant in structure. We define a non-redundant answer structure for a keyword query and a relevance measure for the answer. We suggest a new indexing scheme on the relevant paths between nodes and keyword terms in the graph, and also propose a query processing algorithm to find top-k non-redundant answers efficiently by exploiting the pre-calculated indexes. We present effectiveness and efficiency of the proposed approach compared to the previous method by conducting an experiment using a real dataset.

Background: Level of midwife knowledge is particularly important because of their role in the cervical cancer prevention programme. The aim of this study was to examine differences in the level of knowledge among health care students, midwives and women in the general population of Serbia. Materials and Methods: A cross-sectional approach was used with health care students of the medical shool, midwives in their practice, and women visiting a chosen general practitioner as respondents. Results: In comparison with the students and midwives, women had lower level of knowledge of causative agents of the cervical cancer, genital warts, HPV types, screening for cervical cancer as well as about the target population for vaccine and its role. Differences in the numbers of right answers of respondents were statistically significant (p<0.001). Four or more correct answers were obtained from 22.7% women, 35.3% from midwives and 83.8% from students. Conclusions: Midwives should improve their own level of knowledge related to preventive practice for cervical cancer, as well as their personal compliance with recommended practices, in order to be qualified and credible promoters of cervical cancer control among women in Serbia.
