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.

The purpose of this study is to evaluate the effects of critical friends on self-esteem and the academic oral presentation ability of undergraduate students. A pretest was conducted in the first week of the semester. A pre-academic oral presentation preparation was held from the second week to the seventh week and followed by pedagogical speech activities from the eighth week to the eleventh week. The research instruments are Academic oral presentation behavior and self-esteem evaluation forms. The samples were 37 third year undergraduate students, who were purposively selected from the educational technology class at the Chulalongkorn University. The statistics used for analyzing quantitative data are frequencies, means, standard deviations, one sample t-tests, and Pearson's Product-Moment Correlations. It was found that the 37 third year undergraduate teacher students had higher self-esteem at the statistically significant level of .05 and academic oral presentation scores after the activity were statistically significant at the .05 level.

Since 2008, strategic partnerships have been established between China and Korea. From 2009 to 2019, the bilateral relationship kept a generally stable rate of development with conflicts and uncertainties. It is necessary to study national image construction in the respective mainstream media of the two countries. The present study analyzed Korea-related reports (N = 744) in the People's Daily from 2009 to 2019, aiming to examine the Korean national image framing under Fairclough's three-dimensional Critical Discourse Analysis (CDA) framework: "whatness," "how," and "whyness." The results shed light on what the Korean national image in the People's Daily was and how and why it was framed in that way. This study provided some implications for readers to further recognize the role that media play in constructing a particular image of one country and a frame for researchers to study foreign national image framing in one of China's mainstream newspapers.

An environmentally hot issue has arisen from the plan of Young-Wall Dam Construction at Tong river in Korea lately. The point at issue is which value is bigger between the water conservation for human use in future and the ecosystem protection for the intrinsic value of nature including animals and plants there. The purpose of this study is in the qualitative understanding of college students' critical thinking ability and opinion and the environmental values of them through the analysis of their writings. Various environmental values written in the 7th revised national curriculum of Korea are used as a criteria to investigate students' environmental values in their written opinions. Various environmental values are shown up to be handled such as the anthropocentrism, ecocentrism, pro-technology etc. Students of Dept. of Environment Teaching in the Kongju National University are the subject of this study. It shows that they have a deep understanding of the Young-Wall Dam issue and assert their opinions objectively and critically. Most of them(89.5%, n=17) are against the constructional plan of the Young-Wall Dam. Students who are for the plan are proved to have pro-technology value only and the others who are against to have various values including deer ecology.

Background : Critical pathway is an optional sequencing and timing of interventions by physicians, nurses, and other staff for a particular diagnosis or procedure, designed to minimize delays and resource utilization, and to maximize quality of care; abbreviated versions of case management plans that show critical outcome and key incidents that occur in a predictable and timely fashion to achieve an appropriate length of stay. This study is to develop a critical pathway for vaginal delivery and cesarean section to assess the degree of contentment of the patients and medical personnel and to implement clinical application to see how we could meet the need to guide patients to achieve continuum of care. Method : Critical pathways were developed for normal vaginal delivery and casarean section. LOS(length of stay) target for vaginal delivery was 1 day after delivery & 5 days after C-section. It was distributed to the mother at the OPD and explained thoroughly. It was applied when patients got into the Labor & Delivery Floor. We applied total of 42 patients (30 normal deliveries & 12 C-sections) from February to March, 2000. We performed patient satisfaction survey to all 42 patients, 24 nurses, and 7 residents for internal customer satisfaction. Results : Twenty six patients out of 42 responded to the survey. Twenty one patients out of 26 answered satisfactory. Eighty four percent of 21 respondents replied Critical pathway worked very well. Treatment column got the most compliance. Eleven out of 31 employees thought critical pathway is very helpful for the patient care. Eighteen people didn't see any difference. In their opinion, treatment got the least compliance, which is the contrary to patients opinion. Fifty eight percent of respondents thought that critical pathway can expedite early discharge. Conclusion : Patient satisfaction was higher than we expected but we still need to revise the form. It is recommended to analyze the cost and variance check in the future.

Web-based services have fundamentally confidential problems due to characteristics of internet environment such as anonymity. These problems are serious obstacles to grow the web-based services. The security and confidence of web-based services rely on both service provider and users' opinion. But the former has difficulty in trusting the service provider and the latter takes too long time to propagete all users after converging their opinion. Therefore it is necessary to establish the objective and confidential evaluation and certification program for web-based service. In this paper, the internal and external web-based services evaluation and certification programs are compared and analyzed. The critical factors and evaluation methodology for secure and confidential web-based service are identified. Finally, this paper provides the improvement and strategy for web-based services evaluation and certification program.

Nuclear energy sources are indispensable in cost effectively achieving carbon neutral economy, where public opinion is critical to adoption as the consequences of nuclear accident can be catastrophic. In this context, discussion on spent nuclear fuel is a prerequisite to expanding nuclear energy, as it leads to the issue of radioactive waste disposal. Given the dearth of study on spent nuclear fuel public acceptance, we use text mining and big data analysis on the news article and public comments data on Naver news portal to identify the Korean public opinion on spent nuclear fuel. We identify that the Korean public is more interested in the nuclear energy policy than spent nuclear fuel itself and that the alternative energy sources affect the position towards spent nuclear fuel. We recommend relating spent nuclear fuel issue with nuclear energy policy and environmental issues of alternative energy sources to further promote spent nuclear fuel.

Cryptogenic organizing pneumonia (COP) is a type of idiopathic interstitial pneumonia with an acute or subacute clinical course. Bilateral lung consolidations located in the subpleural area and bronchovascular bundle are the most common findings on chest high-resolution computed tomography. The pathologic manifestations include granulation tissue in the alveoli, alveolar ducts, and bronchioles. COP responds fairly well to glucocorticoid monotherapy with rapid clinical improvement, but recurrence is common. However, treatment with combined immunosuppressant agents is not recommended, even if the COP patient does not respond to glucocorticoid monotherapy with expert opinion.
