This study was aimed at confirming the trends of Taekwondo history research published in academic journals and providing basic data on the direction of history research through this. In order to achieve the purpose of the study, Taekwondo history research trends were analyzed by searching for papers published in domestic academic journals until 2020 with keywords such as Taekwondo history, Taekwondo+History, Taekwondo+Change, Taekwondo+Change, and Taekwondo+Development. A total of 663 studies were collected as a result of the search, of which 221 were used for analysis, excluding data published in 2021, studies unrelated to different events or history, and duplicate data among the collected data when searched for each keyword. In the annual trend of Taekwondo history research, papers were first published in academic journals with the keyword “Taekwondo” in 1970, and the Journal of History Research and Publishing was the most published in the Taekwondo Journal of Kukkiwon and The Korean Journal of History for Physical Education, Sport, and Dance. Research trends related to Taekwondo history were analyzed by dividing them into historical perspectives, technical systems, globalization and sportsization, policies and cultures.

민간투자사업은 민간의 참여를 통해 사회기반시설을 효율적으로 확충하기 위하여 시행되고 있다. 2005년도부터는 기존의 도로, 항만 등을 비롯한 산업기반시설 뿐만 아니라 학교시설, 환경시설 등을 포함한 생활기반시설까지 그 범위가 확대되게 되었다. 따라서 사업의 추진방식도 기존에는 BTO 방식이 주로 이용되었지만 새로이 추가된 민간투자사업에서는 BTL 방식이 도입되게 되었다. BTL 방식은 민간투자 적합 여부를 판단하기 위하여 민간투자 적격성 조사를 실시하며 이는 정량적 VFM과 정성적 VFM으로 구분된다. 본 연구에서는 명확한 결과 도출이 어려운 정성적 VFM의 평가항목을 설정하고 전문가를 대상으로 설문조사를 실시한 후 AHP 기법을 활용하여 상대적 중요도와 가중치를 산정하였다. 이상의 내용은 정량적 VFM과 더불어 정성적 측면의 효율성 및 발생편익을 효과적으로 평가 가능하게 함으로써 BTL 시행여부에 대한 합리적 의사결정을 지원할 것으로 판단된다. PFI(Private Finance Initiative) Project is carried to expand infrastructure effectively through participation of private investment. From the year 2005, the range is expanded not only industrial infrastructure such as made road, harbors and so on but living infrastructure such as school facilities, environmental facilities. For this reason BTL(Build-Transfer-Lease) system is mainly used in new private finance initiative project but in existing private finance initiative project BTO(Build-Transfer-Operate) system was used. BTL system is operated to judge fitness of private investment and classified into quantitative VFM(Value for Money) and qualitative VFM. In this research the estimation item of qualitative VFM which is hard to deduce the effect is created and after surveying of questionnaire in target of experts, relative importance and weight is established with AHP(Analytic Hierarchy Process). By estimating efficiency and benefit of quantitative VFM and qualitative VFM aspect effectively it is expected to support a rational making decision for operating BTL.

심장 외 인공도관 폰탄 술식을 시행한 선천성 심장병 환자에서 도관 천자를 통하여 정맥을 통한 인공 심박동기 삽입을 한 증례는 아직 보고된 바가 없다. 결론적으로 본 증례와 같이 심장 외 인공도관 폰탄 수술을 시행 받은 환자에서도 안전하고 효과적으로 정맥을 통해 인공 심박동기를 삽입하는 것이 가능하리라 생각된다. As the survival rate of patients with complex congenital heart disease has improved and the number of adult patients with congenital heart disease has risen, arrhythmias and heart failure have become important issues in these patients. Cardiac implantable electronic devices, including pacemakers, are also on the rise. Transvenous implantation or epicardial pacemaker implantation is challenging in patients with complex congenital heart disease. Here we report a case in which a dual-chamber pacing, dual-chamber sensing, dual response and rate-adaptive (DDDR) pacemaker was implanted transvenously into a patient with congenital heart disease. A 34-year-old male with extracardiac conduit Fontan circulation complained of dizziness; an electrocardiogram revealed junctional bradycardia. We performed transvenous implantation of a DDDR pacemaker via trans-conduit puncture. In conclusion, transvenous implantation of a pacemaker is feasible in patients with extracardiac conduit Fontan circulation. (Korean J Med 2015;88:299-302)

The development and utilization performance of the construction new technology was introduced in 2014 according to the detailed evaluation criteria of the construction project of Ministry of Land, Infrastructure and Transport. In the case of the construction new technology, the current standard is give 3 points in the "technology development and investment performance" evaluation item. However, construction engineering companies is difficult for to invest the capital required for new technology development. Therefore, in this study, we try to extract the difficult factor that occur in the process of construction new technology development in terms of construction engineering companies. The research results are expected to provide with the support policy guideline for new technology development costs to policy makers.

In this study, the object of studies that form the basic sophistication Taekwondo people, multifaceted manner to analyze the Taekwondo books to aid in the understanding of Taekwondo, providing basic data for future Taekwondo education were placed. The following results were obtained on the basis of a progress puts the needs and objectives of the research results to provide a basis for future analysis of Taekwondo training and multifaceted book(paperback). First, six books the 1960s including the 1959, 10 books the 1970s, 31 books the 1980s, 39books the 1990s, 141books the 2000, and 46books the 2010s by analyzing the results of books it can be seen that stepping aside was total 273 Taekwondo books published are currently. There are 101 synthesis textbooks, 144 books were classified as single object textbooks are compared with 28 literature books. Next to the name is in current textbooks ‘textbook’ was the most common, were often used as the title of the book the ‘Taekwondo’. Analyzed book of theory 107, 37 were classified as group teaching and group teaching and single object textbook. Next, we analyzed a total of 28 separated essay, novel, a fairy tale, and other lilerature. To be published than those with a variety of books related to Taekwondo paperback analyze this would be to establish a systematic method than the Taekwondo school.

Fine dust is known to cause various Respiratory disease and affects human health. Modern people spend 80% of the day living indoors, which means that indoor air quality has a great influence on humans. In particular, infants and children are very vulnerable to the environment. In this study, under the assumption that the fine dust of the outside air is higher than that of the indoor, the inflow of external fine dust is to be prevented through architectural improvement of the school building. As a method of reducing fine dust, an experiment was conducted by adopting a strategy to improve airtightness. The building is a five-story school building, and experiments are conducted in a special classroom. Airtightness performance is measured according to the standard of ISO 9972. In addition, thermal imaging cameras are taken for each construction part and wind speed is measured. To improve the airtight performance, the frame is changed from a single window to a double window. In addition to changing the frame, subsidiary materials for construction were installed to improve airtightness. As a result of architectural improvement, ACH was reduced by 19 to 37%. Wind speed is also reduced by up to 1.2m/s after window improvement. The concentration of fine dust was decreased the most from 0.3 to 0.5 μm. This means that the influence of fine dust introduced from the outside is reduced by improving the airtightness in the fine dust particle size of 0.3 to 1.0. Based on the result of the reduced fine dust concentration, the appropriateness of the indoor fine dust concentration in school facilities was evaluated. Through this research, it is effective to block the inflow of external fine dust through trench replacement and airtight performance improvement technology.
