We have frequently encountered the rapid changes that prevalent opinion of the social community is toppled by a new and opposite opinion against the pre-exiting one. To understand this interesting process, mean-field model with infinite-interaction range has been mostly considered in previous studies S. A. Marvel et al., Phys. Rev. Lett. 110, 118702 (2012). However, the mean-field interaction range is lack of reality in the sense that any individual cannot interact with all of the others in the community. Based on it, in the present work, we consider a simple model of opinion consensus so-called basic model on the low-dimensional lattices (d = 1, 2) with finite interaction range. The model consists of four types of subpopulations with different opinions: A, B, AB, and the zealot of A denoted by $A_c$, following the basic model shown in the work by S. A. Marvel et al.. Comparing with their work, we consider the finite range of the interaction, and particularly reconstruct the lattice structure by adding new links when the two individuals have the distance < ${\sigma}$. We explore how the interaction range ${\sigma}$ affects the opinion consensus process on the reconstructed lattice structure. We find that the critical fraction of population for $A_c$ required for the opinion consensus on A shows different behaviors in the small and large interaction ranges. Especially, the critical fraction for $A_c$ increases with the size of ${\sigma}$ in the region of small interaction range, which is counter-intuitive: When the interaction range is increased, not only the number of nodes affected by $A_c$ but also that affected by B grows, which is believed to cause the increasing behavior of the critical fraction for $A_c$. We also present the difference of dynamic process to the opinion consensus between the regions of small and large interaction ranges.

This study is to know the effect of drama therapy on the sociality of isolated children. To achieve this goal, the following hypothesis was built. Hypothesis I. Dramatherapy program will improve the sociality of isolated children. I -1. Dramatherapy program will improve in cooperation. I -2. Dramatherapy program will improve in independency. I -3. Dramatherapy program will improve in sociability. I -4. Dramatherapy program will improve in law-abiding. To test this hypothesis, the social and emotional isolation test was conducted in 190 children consisting of fifth-grader from N elementary school located in Busan to select 28 children whose founded to be isolated; among these children, eight who wanted to participate in the program were positioned at the experimental group and other eight who didn't want to do and who demonstrated the range of marks similar to the experimental group were positioned at the control group. The dramatherapy program was based on the theory by Robert Landy (2002), Jennings (2003) and Phil Jones (2005) to improve the sociality of isolated children and was implemented in a total of 15 sessions, two sessions a week after school. To test the effect of the program, A modified test paper by Suh, Poongyeon (1991) with the content of testing sociality into a test paper of human nature for elementary school students to be made by Jeong, Bummo (1971) was used which consists of four sub-factors: cooperation, independency, sociability, law-abiding. As a quantitative analysis, Mann-Whitney Test were analyzed for experimental and control groups. As a qualitative analysis, the interaction patterns among student were analyzed on he basis of video tapes. The tool of observe the interaction patterns among student was Interaction Process Analysis System which was made by Bales (1970). This study obtained the following result First, the drama therapy had meaningful effect on the sociality of the sociality of isolated children. But the quantitative change of the sociality test conclusion was showed meaningfully and positive social behavior was increased in periodical process analysis. Second, in the Interaction Process Analysis(IPA) affirmative interactions increased and negative interactions decreased.

The study seeks to widen the discussion from healthcare oriented 'health publicness' to human security oriented 'health publicness'. The shortcomings of previous literatures on health publicness are as follows: (1) the studies have confined the range of discussions to healthcare system, (2) lacked arguments from political perspectives, and (3) failed to provide actionable pathways to achieve the goal. Thereby, we suggest 'health publicness' based on the concept of human security to solve multidimensional healthcare problems. The health publicness based on human security, which aims to secure everybody's freedom from want and fear, enables not only to expand the scope of health problems that can be discussed but also to propose the procedures to achieve health publicness. More specifically, it consists of substantive and procedural health publicness. The former is about 'health security'-protecting, maintaining, and promoting individual's health-whereas, the latter is about 'social dialogue' guaranteeing participation of citizens, government, employers, and worker representatives. In conclusion, this study proposes the 'Regional Healthcare Quadripartite' as the incarnation of health publicness involving a variety of actors within and across the healthcare system.

Delay in help-seeking behaviour which is potentially preventable has a major effect on the prognosis and survival of patients with breast cancer. The objective of this study was to explore reasons for delay in seeking help among patients with breast cancer from the East Coast of peninsular Malaysia. A qualitative study using face-to-face in-depth interview was carried out involving 12 breast cancer patients who had been histo-pathologically confirmed and were symptomatic on presentation. Respondents were selected purposely based on their history of delayed consultation, diagnosis or treatment. All were of Malay ethnicity and the age range was 26-67 years. Three were in stage ll, seven in stage lll and two in stage lV. At the time of interview, all except one respondent had accepted treatment. The range of consultation time was 0.2-72.2 months with a median of 1.7 months, diagnosis time was 1.4-95.8 months( median 5.4 months )and treatment time was 0-33.3 months (median 1.2 months). The themes derived from the study were poor knowledge or awareness of breast cancer, fear of cancer consequences, beliefs in complementary alternative medicine, sanction by others, other priorities, denial of disease, attitude of wait and see and health care system weakness. Help-seeking behaviour was influenced by a complex interaction of cognitive, environmental, beliefs, culture and psycho-social factors. Breast cancer awareness and psychological counselling are recommended for all patients with breast symptoms to prevent delay in seeking clinical help.

The information space, the main components of which are information resources, means of information interaction, and information infrastructure, is a sphere of modern social life in which information communications play a leading role. The objective process is the gradual but stable entry of the national information space into the European and world information sphere, in the context of which there is a legitimate question of its protection as one of the components of the national security of Ukraine. However, the implementation of this issue in practice immediately faces the need to respect the rights and fundamental freedoms guaranteed by international regulations and the Constitution of Ukraine, especially in the field of cybersecurity. The peculiarity of the modern economy is related to its informational nature, which affects the sharp increase in cyber incidents in the field of information security, which is widespread and threatening and affects a wide range of private, corporate, and public interests. The problem of forming an effective information security system is exacerbated by the spread of cybercrime as a leading threat to information security both in Ukraine and around the world. The purpose of this study is to analyze the state of cybersecurity and on this basis to identify new areas of the fight against cybercrime in Ukraine. Methods: the study is based on an extensive regulatory framework, which primarily consists of regulatory acts of Ukraine. The main methods were inductions and deductions, generalizations, statistical, comparative, and system-structural analysis, grouping, descriptive statistics, interstate comparisons, and graphical methods. Results. It is noted that a very important component of Ukraine's national security is the concept of "information terrorism", which includes cyberterrorism and media terrorism that will require its introduction into the law. An assessment of the state of cybersecurity in Ukraine is given. Based on the trend analysis, further growth of cybercrimes was predicted, and ABC analysis showed the existence of problems in the field of security of payment systems. Insufficient accounting of cybercrime and the absence in the current legislation of all relevant components of cybersecurity does not allow the definition of a holistic system of counteraction. Therefore, the proposed new legal norms in the field of information security take into account modern research in the field of promising areas of information technology development and the latest algorithms for creating media content.
