Purpose - This paper examines how the consumer animosity of partner country influences the purchase of foreign products. We analyzed news sentiment to determine whether Chinese consumer's animosity affect the purchase of the products made in Korea around the time when the U.S. Terminal High Altitude Area Defense missile system was deployed in South Korea. Design/methodology - To measure the tone of Chinese consumer animosity more carefully, we utilized a text mining technique of the Chinese language to read the public's opinion. Using Chinese news paper's editorials of 2015.1-2018.10, we analyzed the sentiment toward Korea and regressed it with Korean export to China. Findings - Empirical results report that Chinese consumers tended to reduce their purchase of consumer goods from Korea when the animosity increased, that is, the sentiments of Chinese news editorials were negative. In contrast, the animosity did not affect the purchase of Korean intermediates or raw materials. We further analyzed the effect by dividing the animosity into three categories; politics, economics, and culture. Among these groups, political news exhibits a unique effect on Chinese purchase on consumer goods from Korea. Originality/value - Existing literature on animosity models has measured the animosity by collecting the consumers' opinions through survey at a given time point, whereas it is measured by analyzing the tone of the press release by sentiment analysis during the time period around the event occurrence in this study.

Objective: To elucidate the use of radiological studies, including nuclear medicine, and biopsy for the diagnosis and staging of prostate cancer (PCA) in clinical practice and understand the current status of PCA in Asian countries via an international survey. Materials and Methods: The Asian Prostate Imaging Working Group designed a survey questionnaire with four domains focused on prostate magnetic resonance imaging (MRI), other prostate imaging, prostate biopsy, and PCA backgrounds. The questionnaire was sent to 111 members of professional affiliations in Korea, Japan, Singapore, and Taiwan who were representatives of their working hospitals, and their responses were analyzed. Results: This survey had a response rate of 97.3% (108/111). The rates of using 3T scanners, antispasmodic agents, laxative drugs, and prostate imaging-reporting and data system reporting for prostate MRI were 21.6%-78.9%, 22.2%-84.2%, 2.3%-26.3%, and 59.5%-100%, respectively. Respondents reported using the highest b-values of 800-2000 sec/mm² and fields of view of 9-30 cm. The prostate MRI examinations per month ranged from 1 to 600, and they were most commonly indicated for biopsy-naïve patients suspected of PCA in Japan and Singapore and staging of proven PCA in Korea and Taiwan. The most commonly used radiotracers for prostate positron emission tomography are prostate-specific membrane antigen in Singapore and fluorodeoxyglucose in three other countries. The most common timing for prostate MRI was before biopsy (29.9%). Prostate-targeted biopsies were performed in 63.8% of hospitals, usually by MRI-ultrasound fusion approach. The most common presentation was localized PCA in all four countries, and it was usually treated with radical prostatectomy. Conclusion: This survey showed the diverse technical details and the availability of imaging and biopsy in the evaluation of PCA. This suggests the need for an educational program for Asian radiologists to promote standardized evidence-based imaging approaches for the diagnosis and staging of PCA.

Purpose: By identifying the actual profile of emergency medical personnel's pre-admission infection control practices, this study intended to provide a basic reference material for the improvement and reorientation of pre-admission infection control measures, and thereby help establish an effective plan for pre-admission infection control activities. Methods: Total 119 EMT's working for Jeollabuk-do Provincial Fire Defense HQ were asked to join a structured questionnaire survey from June to August 2006. Results: 1. It was found that 56.1% respondents answered no guideline available on the prevention of infection. Out of our rescue brigade members who knew about relevant guideline available, 34.2% respondents answered that their department conducted quality control program for the guideline. 2. For protective outfit in emergency practice, it was found that most respondents put on gloves or nothing at all(38%), which was followed by sterile gloves(29.2%), disposable mask(26.9%), gown(4.3%) and protective goggle(1.6%). And it was noted that all respondents(100%) washed out any clothing contaminated with somatic secretion on their own. 3. For a question about any experience in emergency activities exposed to infectious diseases, it was found that most of all respondents(77.9%) answered 'No', which was followed by 'Don't Know'(18.6%) and Yes(3.9 %). 4. For a question about any experience in inquiring of patients about infectious diseases, it was found that most respondents(49.4%) answered 'Yes' and 'Sometimes'(9.1%). It was noted that 20.2% respondents had extra medical examination in medical institution in terms of whether they were exposed to infectious diseases, apart from regular medical examination. Conclusions: In order to protect 119 EMT's from infectious diseases, it will be necessary to acquire emergency medical staffs specializing in infection control and organize corresponding personnel training units to keep providing reorientation and evaluation. In addition, it will be also necessary to supply them with a full set personal protection apparatuses and other equipments required for disinfection and sterilization.

The predominant concern of the study consist of: (1) the direct effect of Chinese's sense of rivalry toward Korea and receptiveness to foreign cultural inflow on national defense respond; (2) the mediating effect of the reasonable dispute resolution between China and Korea; (3) the moderating effects of liking for Korean Wave. The research is based on a survey conducted with 695 Chinese people under 30, located in eleven cities of seven provinces. The notable findings are as follow: First, while the sense of rivalry does not negatively effect on the reasonable dispute resolution between China and Korea among group with high liking for Korean Wave, the sense of rivalry does have negative effect on the dispute resolution among Chinese with low liking for Korean Wave. Second, the reasonable dispute resolution shows a buffer effect between the receptiveness to foreign cultural inflow and the sense of rivalry toward Korea among group with high liking for Korean Wave, however, the mediation effect of the reasonable dispute resolution is not significant among low group. Thus, it is proved that the moderating effect of liking for Korean Wave is significant. Some practical and political implications are discussed based on the study's findings.

EST analysis was performed to identify stress-responsive and immune-related genes from rock bream (Oplegnathus fasciatus). cDNA libraries were constructed with liver and randomly chosen 624 clones were subjected to automated sequence analysis. Of 624 clones sequenced in total, approximately 15% of ESTs was novel sequences (no match to GenBank) or sequences with high homology to hypothetical/unknown genes. The bioinforamtic sequence analysis including functional clustering, homology grouping, contig assembly with electronic northern and organism matches were carried out. Several potential stress-responsive biomarker and/or immune-related genes were identified in all the tissues examined. It included lectins, ferritins, CP450, proteinase, proteinase inhibitors, anti-oxidant enzymes, various heat-shock proteins, warm temperature acclimation protein, complements, methyltransferase, zinc finger proteins, lysozymes, macrophage maturation associated protein, and others. This information will offer new possibilities as fundamental baseline data for understanding and addressing their molecular mechanism involved in host defense and immune systems of this species.

This study is written to bring the proposal forward for the direction of south korean naval force. The political situation and the circumstance of the world, especially in the area of Pacific Ocean, are changing very rapidly. North Korea has been always the conventional existing intimidator for South Korea since the 6·25-War. Additionally, the strengthening movements of the national defense, which is easily noticed from China and Russia, is also an other part of intimidating countries against South Korea. Those three mentioned countries are continually developing the asymmetrical warfare systems, for example a strategic nuclear weapon. Since the Obama Administration, the Asia-Pacific Rebalancing-Strategy has been changed as an East Asian foreign policy. Nowadays, Trump Administration renamed the 'United States Pacific-Command' to 'United States Indo-Pacific Command'. The purpose of this is not only letting India to participate in american alliance, but also reducing an economic burden, which is often mentioned in USA. West Germany was located in the very similar geopolitical position during the Cold War just like South Korea these days. And that's why the strategy of West German Navy is worthy of notice for south korean naval force to decide its suitable strategy. Most of all, the two most important things to refer to this study are the plan to expand naval air force and the realistic political stand for us to take it. In conclusion, I laid an emphasis on maintenance of 'green-water-navy'. instead of selecting the strategy as a 'blue-water-navy'. The reason I would like to say, is that south korean navy is not available to hold the unnecessary war potential, just like Aircraft-Carrier. However, this is not meaning to let the expansion of naval force carelessly. We must search the best solution in order to maintain the firm peace within the situation. To fulfill this concept, it is mostly very important to maintain the stream of laying down a keel of destroyers, submarines and air-defense-missile, as well as the hight-tech software system, taking a survey of 4th industrial revolution. Research and development for the best solution of future aircraft by south korean navy is likewise necessary. Besides, we must also set the international diplomatic flexibly. As well as maintaining the relationship with US Forces, it is also very important to improve the relationship with other potential allied nation.
