  • The space radiation dose over air routes including polar routes should be carefully considered, especially when space weather shows sudden disturbances such as coronal mass ejections (CMEs), flares, and accompanying solar energetic particle events. We recently established a heliocentric potential (HCP) prediction model for real-time operation of the CARI-6 and CARI-6M programs. Specifically, the HCP value is used as a critical input value in the CARI-6/6M programs, which estimate the aviation route dose based on the effective dose rate. The CARI-6/6M approach is the most widely used technique, and the programs can be obtained from the U.S. Federal Aviation Administration (FAA). However, HCP values are given at a one month delay on the FAA official webpage, which makes it difficult to obtain real-time information on the aviation route dose. In order to overcome this critical limitation regarding the time delay for space weather customers, we developed a HCP prediction model based on sunspot number variations (Hwang et al. 2015). In this paper, we focus on improvements to our HCP prediction model and update it with neutron monitoring data. We found that the most accurate method to derive the HCP value involves (1) real-time daily sunspot assessments, (2) predictions of the daily HCP by our prediction algorithm, and (3) calculations of the resultant daily effective dose rate. Additionally, we also derived the HCP prediction algorithm in this paper by using ground neutron counts. With the compensation stemming from the use of ground neutron count data, the newly developed HCP prediction model was improved.

  • The purpose of this study is to clarify the historical circumstances under which the Korean Pavilion was established at the 1900 Paris Exposition Universelle, and the construction process and design features of the pavilion building. At that time, even though Korea faced difficulty due to lack of experience in the world exposition and funds, Korea attempted to positively participate in the international cultural event by establishing the Korean Pavilion under an official contract with assistance of the French Government. Moreover, the Pavilion shows significant architectural features which had not been shown until then in terms of the structure and design of the pavilion building. In this connection, in this thesis, among others, the historical circumstances under which the "Korean Pavilion" was established at the 1900 Paris Exposition Universelle, and the construction process as well as the process and features of the draft design prepared at an early stage by Baron Delort de Gleon on the part of France among the above parties to the project for construction of the Korean Pavilion, which have never been addressed in the field of architecture or interior due to lack of existing data, will be clearly studied based on relevant literatures. According to analysis of the study, it reveals that the representation method for the Korean tradition of Korean Pavilion designed by Baron Delort de Gleon was based on the Chinoiserie, the style widely seen in Europe. In addition, Delort de Glean's commerce-oriented concept is integrated into the design of the Korean Pavilion as well.

  • 클라이언트/서버 방식에서의 파일공유시스템은 높은 성능과 용량의 서버를 요구하게 되고 이러한 서버는 매우 값비싸고 관리가 복잡하며 플랫폼에 영향을 많이 받게 된다. 또한 서버에 맞는 메모리나 하드 드라이브 둥의 확장은 많은 비용을 초래한다. 반면에 P2P(peer to pee.)환경에서의 파일공유방식은 PC(클라이언트)에 있는 파일들을 한 서버에 올려놓고 그 파일들을 관리하는 클라이언트/서버방식에서의 값비싼 서버를 사용하지 않고 클라이언트 컴퓨터들만을 사용하여 자료의 공유 및 관리를 분산함으로 인해 대용량서버를 구입함으로써 발생하는 인적, 물적 자원의 낭비를 최소화 할 수 있을 것이다. 또한 사용자의 수가 늘어날수록 연산, 협업의 성과가 높아지는 둥의 혜택을 제공한다. 이와 같은 이유로 인해 많은 사람들이 P2P에 관심을 갖게 하고 또한 현재 각광받고 있는 모바일 관련 분야에도 P2P를 이용한 연구들이 활발하게 진행되고 있다.

  • Purpose: Trauma surgery is not an official medical specialty in the Republic of Korea (South Korea). Thus, a trauma victim transported to an emergency room (ER) is resuscitated and surveyed by an intern, a resident, or an emergency physician (EP) at first. Currently an operative management is decreasing because of multiple factors. Nevertheless, trauma surgery is the key for some patients. Does the EP's treatment in the ER delay the surgeon's emergency operation? Methods: A retrospective study was performed for trauma victims who underwent trauma surgery from March 2004 to February 2005 in a local emergency center of Daegu-city. We reviewed the medical records and analyzed the trauma victim's age, sex, cause of injury, method of transport, time from the trauma to the operation, EP's treatment, surgical department, mortality, and injury severity score (ISS). Results: Of the 223 trauma victims included in this study, males were predominant (83.4%). The mean age was 37.98 years of age. The main Causes of trauma were trauma NOS (not otherwise specified) and motor vehicle accidents (MVA). The main methods of transport was privately owned automobile. The mean time from trauma to operation was 617.46 min. The mean ISS was 7.67. Trauma surgery with the EP's treatment group included 40 trauma victims with higher ISS, and the time from trauma to operation was shorter than it was for the 183 trauma victims not in that group. Conclusion: The EP's treatment of high-ISS multiple-injury trauma victims can shorten the time from trauma to trauma surgery and will help the surgical department treatment. In the trauma care system of the Republic of Korea, and increased role should be encouraged for emergency physician.

  • Fintech, which stands for financial technology, is growing fast globally since the economic crisis hit the United States in 2008. Fintech companies are striving to secure a competitive advantage over existing financial services by providing efficient financial services utilizing the latest technologies. Fintech companies can be classified into several areas according to their business solutions. Among the Fintech sector, peer-to-peer (P2P) lending companies are leading the domestic Fintech industry. P2P lending is a method of lending funds directly to individuals or businesses without an official financial institution participating as an intermediary in the transaction. The rapid growth of P2P lending companies has now reached a level that threatens secondary financial markets. However, as the growth rate increases, so does the potential risk factor. In addition to government laws to protect and regulate P2P lending, further measures to reduce the risk of P2P lending accidents have yet to keep up with the pace of market growth. Since most P2P lenders do not implement their own credit rating system, they rely on personal credit scores provided by credit rating agencies such as the NICE credit information service in Korea. However, it is hard for P2P lending companies to figure out the intentional loan default of the borrower since most borrowers' credit scores are not excellent. This study analyzed the voices of telephone conversation between the loan consultant and the borrower in order to verify if it is applicable to determine the personal credit score. Experimental results show that the change in pitch frequency and change in voice pitch frequency can be reliably identified, and this difference can be used to predict the loan defaults or use it to determine the underlying default risk. It has also been shown that parameters extracted from sample voice data can be used as a determinant for classifying the level of personal credit ratings.

  • Background: This paper was to investigate Korean medical disputes through the cases of asking Korean Acupuncture and Moxibustion Medicine Society(KAMMS) for medical consultation Methods: In this study, it was investigated 66 medical disputes requested to KAMMS for medical consultation from April, 2013 to December, 2017. The cases of disputes were classified according to the year, month, sex, age, area, original disease, treatment method and type of occurrence. Results : There were 66 cases from April, 2013 to December, 2017 that able to investigate. There were no annual increases and decreases or monthly trends in medical disputes. In characteristics of patients, female (53.03%) were more likely than male, and the age distribution was in in 50s (24.24%). It occurred in area, followed by Gyeongsang (33.33%), Gyeonggi-Incheon (30.30%), and Seoul (13.64%). The majority of original disease was musculoskeletal disease (81.82%), and treatment methods that have been assumed to cause medical disputes were 38 cases (57.58%) of acupuncture, followed by 12 cases (18.18%) of combined treatment. Analysis of occurred disease showed that 23 cases (34.85%) of musculoskeletal diseases were the most common, followed by 17 cases (25.76%) of infection. When original disease was musculoskeletal disease, the greatest type of occurrence was musculoskeletal disease (30.30%), but there was no statistical significance. Musculoskeletal disease was common after acupuncture (28.80%), and infection was common after combined treatment (12.10%). It was statistically significant. Although no statistically significant, pharmacopuncture tended to cause the immune response, while moxibustion tended to cause burns.
