  • Background: Information about the epidemiology of venous thromboembolism (VTE) recurrence in Korea is lacking. The purpose of this study was to investigate VTE cumulative recurrence rates and identify risk factors for VTE recurrence among Korean adults. Methods: A retrospective cohort study was conducted on adult patients (${\geq}18years$) admitted to a university teaching hospital for pulmonary embolism (PE) from 2005 to 2013. The main outcome of interest was a recurrence of VTE. We used Cox proportional hazard regression analyses to calculate the relative risk of VTE recurrence. Results: Five-year cumulative incidence of recurrent VTE events was 21.5% (95% confidence interval [CI], 17.7-25.4) in all cases of PE; 17% after provoked and 27% after unprovoked PE. Multivariate analysis showed that body mass index (BMI) of ${\geq}25$ (hazard ratio [HR], 2.02; 95% CI, 1.17-3.46; p=0.01) and longer anticoagulation therapy duration (HR, 0.90; 95% CI, 0.84-0.96; p<0.01) were independently associated with risk of VTE recurrence. Risk factors not found to be statistically significant at the <0.05 level included history of VTE (HR, 1.81; 95% CI, 0.84-3.88; p=0.12), unprovoked PE (HR, 1.70; 95% CI, 0.89-3.25; p=0.10), symptomatic deep vein thrombosis (HR, 1.62; 95% CI, 0.89-2.94; p=0.10), and female sex (HR, 1.42; 95% CI, 0.78-2.55; p=0.24). We found that age, history of cancer, and other co-morbidities did not significantly affect the risk of VTE recurrence. Conclusion: Recurrence of VTE after PE is high. Patients with BMI ${\geq}25$ or reduced anticoagulation therapy duration have a higher risk of recurrent VTE.

  • With the worldwide spread of African swine fever, interest in livestock epidemics is growing. Livestock transport vehicles are the main cause of the spread of livestock epidemics, but no empirical quarantine procedures and standards related to the mobility of livestock transport vehicles in South Korea. This study extracted livestock-related vehicles' trajectory by utilizing the facility visit history data from the Korea Animal Health Integrated System and the DTG (Digital Tachograph) data from the Korea Transportation Safety Authority and presented them as exposure indexes aggregating the link-time occupancy of each vehicle. As a result, a total of 274,519 livestock-related vehicle trajectories were extracted, and exposure values by link and zone were quantitatively derived. Through this study, it is expected that prior monitoring of livestock transport vehicles and the establishment of post-disaster prevention policies would be provided.

  • Fermented milks have been recognized as healthy foods since ancient times, but those using intestinal bacteria such as Bifidobacterium and lactic acid bacteria (LAB) are even more valuable from the standpoint of view of maintaining health. They have also now come to be recognized as important in the field of preventive medicine. Although advances in the medical sciences in the last 50 years have significantly increased the human lift span, an unfortunate fact is that many of us are now living long enough to experience chronic disorders such as coronary heart disease, hypertension, osteoporosis, diabetes and cancer. In recent years there has been renewed interest in health promotion and disease prevention by incorporating probiotic bacteria into foods to counteract harmful bacteria in the intestinal tract. Therefore, there are now a wide variety of commercial products containing prospective probiotics that claim health-promoting effects, such reductions in large botvel carcinogens and mutagens, antitumor properties, cholesterol-lowering effects, increased lactose digestion, relief from con-stipation, stimulation of immunocomponent cells and enhancement of phagocytosis. Two well-known representative probiotic is LAB and Bifidobaclerium. Traditional probiotic dairy strains of LAB which have been designated as GRAS (Generally Recognized As Safe) bacteria have a long history of safe use and most strains are considered comestible microorganisms with no pathogenic potential. Accordingly, there is considerable interest in extending the range of foods containing probiotic organisms from dairy foods to infant formulas, baby foods, and pharmaceuticals. In addition, the ingestion of probiotics, prebiotics, and symbiotic as wll as combinations of pro- and prebiotics has recently aroused renewed interest as enhancing the beneficial relationship between the host and intestinal microflora in both healthy and diseased indivisuals. Non-communicable chronic diseases such as cancer, cerebral hemorrhage, is chemic heart disease, and diabetes mellitus has recently been recognized as adult diseases in Japan as well as other countries. and are considered to be inevitably associated with aging. These diseases occur as a result of individual life styles. The Japanes Government. Ministry of Health, Labor and Welfare has proposed substituting the term 'adult diseases' with 'lifestyle-related diseases'. It has emphasized the importance of prevention rather than treatment. since the well-known increase in the elderly population in Japan is predicted to result in a variety of socioeconomic problems. n this lecture on the Present status of fermented milk products in Japan, I will report a strategy for the development of fermented milk products in Japan from the standpoint of view of research in Japan on LAB and Bifidobacteria. They could play an important role in preserving human health by controlling intestinal microflora capable of producing toxic effects on the host.

  • In this paper, we propose a method to recognize the action direction of human by developing 4D space-time (4D-ST, [x,y,z,t]) features. For this, we propose 4D space-time interest points (4D-STIPs, [x,y,z,t]) which are extracted using 3D space (3D-S, [x,y,z]) volumes reconstructed from images of a finite number of different views. Since the proposed features are constructed using volumetric information, the features for arbitrary 2D space (2D-S, [x,y]) viewpoint can be generated by projecting the 3D-S volumes and 4D-STIPs on corresponding image planes in training step. We can recognize the directions of actors in the test video since our training sets, which are projections of 3D-S volumes and 4D-STIPs to various image planes, contain the direction information. The process for recognizing action direction is divided into two steps, firstly we recognize the class of actions and then recognize the action direction using direction information. For the action and direction of action recognition, with the projected 3D-S volumes and 4D-STIPs we construct motion history images (MHIs) and non-motion history images (NMHIs) which encode the moving and non-moving parts of an action respectively. For the action recognition, features are trained by support vector data description (SVDD) according to the action class and recognized by support vector domain density description (SVDDD). For the action direction recognition after recognizing actions, each actions are trained using SVDD according to the direction class and then recognized by SVDDD. In experiments, we train the models using 3D-S volumes from INRIA Xmas Motion Acquisition Sequences (IXMAS) dataset and recognize action direction by constructing a new SNU dataset made for evaluating the action direction recognition.

  • Theories of Li-Ki mutual dynamism and piety represent philosophical thoughts of Toege School. The theory of Li-Ki mutual dynamism reflects conflicts of Heavenly Law and Human Desire or Principled Mind and Selfish Mind on the private level, but conflicts of Virtuous Gentleman and Materialistic Person on the social level. The theory of piety is for establishments of Heavenly Law's Superintendence and Virtuous Gentleman's Leading Power in life. Toege's followers keep this theoretical stream Their perception of reality has two distinct features: one is that they focus on the fundamental distinguished from the incidental: the other is that they don't tolerate any compromise between righteousness and interest, They think they can make a beautiful world without any compromise between righteousness and material interest if trying hard on the fundamental. Their propensities are very different from those of Yulgok school who sought an appropriate compromise between principle and reality or between the Eastern and the Western party distinguishing an argument of the fundamental from an argument of the incidental.

  • The Engineering school of Tohoku University has been offering a Team-based Engineering Design Course to its first year students since 1996 in order to increase the level of both motivation and interest in engineering. Freshmen are required to select one of approximately 150 topics and do some research on this topic. This course also provides opportunities for students to participate in exchange programs with the University of Washington (UW) and the University of Science and Technology Beijing (USTB). In the Tohoku-UW exchange program, which began in 1999, between 10 and 25 students of Tohoku visit the UW annually to present the results of the subjects the school has appointed in advance in the Team-based Engineering Design Course. In the Tohoku-USTB exchange program, which began in 2007, about 15 students from each university participate in a one day meeting organized by the students themselves. They give a presentation on either the results of the subject they selected in the course, or on an engineering related topic both groups have agreed to in advance. In this paper, a detailed history, the objectives, a schedule and the budget in these unique exchange programs is introduced together with an outline of the course and its contribution to the engineering design education.

  • The entrepreneurial university concept is a new challenge and opportunity for science and technology universities in Korea. The traditional university functions of education, research, and community service are still highly relevant, but increasingly so are new types of collaboration for research outcomes and funding resources. Strategic university management is needed to handle socioeconomic contribution, involving the creation and maintenance of proactive relationships with firms, national and regional governments, and other regional entities. The emergence of the entrepreneurial university in Korea is similar to the socioeconomic changes observable in the history of university development in America and in many other developed countries. In this paper, we examine the emerging paradigm of entrepreneurial universities in Korea and discuss the interactions among universities, firms, and government strategy and policy by investigating and comparing two universities, POSTECH and KAIST, in their leadership, adaptation to changes in the environment, business strategies, organization, and cooperative network. We conclude with policy points that emphasize the fact that while entrepreneurial universities are an emerging concept, they can expand innovation and creativity in education and research in Korean universities in the mid-to-long term if university administration, policymakers and public administrators, and regional innovation actors take an interest in the need for a new organization and system where university research can contribute socioeconomically.

  • It is meaningful in that it can be used as valuable data in modern nursing by exploring the meaning and essence of the experiences experienced as women and nurses in the special situation of war to understand their experiences. To find the role of nurses in the war, the research was classified into primary data and secondary data. Among the many data, only those with high external and internal evaluations were selected and analyzed. However subjective opinions were not included. At a time when women's social advancement was difficult, the nurse faithfully fulfilled the role of a nurse on the battlefield, and as a result, it became a new channel for women's social advancement. Nurses performed various roles, such as nursing for soldiers wounded in the Korean War, as well as midwifery and health education for the general public. In this way, during the Korean War, both inside and outside the battlefield, nurses performed all the roles they could in their respective positions. Nursing activities on the battlefield have taken their true value in line with the characteristics of nursing education based on holistic nursing, integrated thinking, love for humanity, and dedication. Recently, disasters and war zones are increasing worldwide, and the number of nurses required in these fields is also increasing. Based on the research results of past nurses' activities, there is a need for interest and research on the new roles of nurses needed in the present and future society. In addition, while not forgetting the sacrifices of nurses in the past, this spirit must be continued and developed.

  • As the COVID-19 continues spreading, Korea's Ministry of Education (MOE) announced that all public schools, including elementary, middle, and high schools, must begin on April 9, 2020, via online teaching for the first time in the nation's history. There were opposite views among educators regarding the unprecedented attempt to start school online. This study intends to analyze the strategies and policies of distance learning in the public education sector using the experiences in Korea, which has been dealing with the COVID-19 pandemic over the past six months, and thus presents educational implications that may be of interest other countries in the post-COVID-19 era. This study first conceptualized the distance education policy in two domains: technological infrastructure and technological teaching and learning, and then examined what specific policies have supported distance education in school settings. For the analysis of policies supporting distance education in Korea, this study analyzed the relevant documents that include the annual plan and press release uploaded on the website of MOE from early March until early August. Accordingly, 13 documents that contain the distance education policy were analyzed in this study. To provide equal opportunities for all students and ensure fair resource allocations, technological inequality should be discussed in the context of educational inequality. Finally, this study looks at how strategies and policies could be related to educational equality and equity.

  • This study can be divied into three major sections: 1. Background on the 1980s : The 1980s can be characterized as a era of rising expectations over the quality of life. Interest in art, history, culture, and new technology increased to appeal to a greater audience. In fashion, these changes led to greater focus on quality and unique stylishness as fashion represented a medium through which luxury and refined tastes could be expressed. 2. Textile Trends of the 80s Divided into 4 Periods : The period of 1980-82 saw the mixture of natural lines with constructive lines. The textiles used in fashions in this period can be characterized by natural materials, mannish materials of the 1950s, feminine materials of the 1920s and 30s, and spoty materials of the 1960s. The period of 1983-85 was an avante garde period which used rustic avante-garde materials and art craft materials. The period of 1986-87 can be described as minimalistic and neo-classical which incorporated materials which represents a metropolitan feel, retro decorative materials and sporty, futuristic mat-erials. Lastly, the period of 1988-89 produced ethnic and natural fashions which relied on traditional British materials, country elegant and innocent look fabrics, ethinic and ecology-minded materials, in addition to comfortable and sports casual materials. 3. Characteristrics and methods of expression for textiles in the 1980s, : In the 1980s, the development of textiles have can be divided into 4 distinct patterns: decorative materials, sporty materials. In generals textiles have increased in their decorative nature-especially decoration by texure. Textile have also incorporated the mixture of contrasting themes in order to create new fabrics.
