Cubic Spline을 사용한 최적 캠곡선의 합성

손태영,양민양 대한기계학회 1995 대한기계학회논문집 Vol.19 No.5

The application of cubic spline is presented for basic curve (DRD motion) of cam motion. The purpose of this paper is to achieve better dynamic characteristics than general cam curves. A cubic spline is a piecewise function that is continuous in displacement, velocity and acceleration. The best cam curve is obtained by changing the weights of the object function. So the method can be used to any machine system case by case. For the proposed object function, the result has improved all characteristics such as velocity, acceleration and jerk compared with that of the modified sine curve.

Gas 버너 소화 안전장치에 관한 연구

손태영,김창동 동의공업대학 1998 論文集 Vol.24 No.1

Presently many companies used the cast burner for high capacity heat. The cast burner can readily produce the high capacity heat hand. The cast burner is a simple inexpensive structure. But it does not have safety construction that can cut the gas supply during leakage. So this defect can produce explosion danger. Resently, a cast burner(DA-701) with a function that can cut leakaging gas automatically came to the stage. But this burner has defective point, such as the two channel structure with ball type, expensive cost and a few applications. Therefore this paper's aim is to develop the cast burner for cheap cost and safe construction that can attach and solve.

OTT 기반 영상콘텐츠 제작 스타트업의 스케일업 (Scale-up) 전략 분석 연구 . 와이낫미디어 사례를 중심으로

손태영 한국방송학회 2023 한국방송학보 Vol.37 No.5

Recently, the media industry is changing rapidly with the growth of OTT, and the industry is reorganizing around the content. However, domestic production companies, which should play an important role in this era, are still questioning the possibility of growth due to unfair practices with broadcasters. Therefore, this study tried to find out the implications for the problems facing production companies through the growth case of video content production startup "Whynot Media," which stands out based on OTT even in this situation. To this end, dynamic capabilities theory, which is easy to analyze corporate capabilities and strategies in a rapidly changing environment, was applied, and Whynot Media's strategy and growth process were analyzed in terms of 'Sensing', 'Seizing', and 'Reconfiguration', which are components of dynamic capabilities. As a result of the study, it was confirmed that OTT First, content IP possession, upbringing and utilizing rookies, participation in advertising business, high data utilization, business diversification, and internal process advancement showed different strategies and capabilities from common TV production companies. In addition, it was inferred that these strategic choices and accumulated capabilities affected not only the success of content and various business, but also the financial performance such as sales and total assets with steady and high growth. Through these analysis results, this study drew implications that in order for small and medium-sized production companies to grow, it is necessary to secure content IP, discover cash cow business, establish signature processes, and establish management strategies through careful analysis of markets and products.

글로벌 가치 사슬 관점에서의 한국 포맷 산업 글로벌 경쟁력 분석 : 언스크립티드 포맷(Unscripted Format) 분야를 중심으로

손태영 한국방송학회 2023 방송통신연구 Vol.- No.122

This study analyzed the changes in the Korean format industry for about 10 years sincethe 2010s, the structural changes of the Korean format industry in terms of industrialstructure, and the response of Korean broadcasting content companies in terms ofcompanies. And through this, I tried to examine whether the Korean format industry iscompetitive in the global format market. As a result of the study, the Korean format industry seems to have some global competitiveness. First of all, the global competitiveness in format creation capabilities was confirmed through rising format transactionperformance and diversification of format transaction that continued after <King ofMask Singer>. In addition, domestic broadcasting content companies are increasingtheir format business capabilities, and new companies participating in format businesshave emerged in the area of independent producers. The government's policy to support Korean format industry, which has been steadily supported since 2009, is also considered to have played a role in this as well. But there are not only positives. This is because K-format is currently well-received in the global market, but its profitability andthe scale of exports are not good. Therefore, in order to continue and strengthen theglobal competitiveness of the Korean format industry, the focus should be on improvingthe profitability of the format business and expanding the size of the transaction. And ifthe industry and the government consider ways to improve this together, the Koreanformat industry will be able to develop further. On the other hand, it should be notedthat this study may cause bias because there are cases where the scripted and unscripted fields are not clearly distinguished from the statistical data related to domesticand foreign formats.

로타바이러스 백신 도입 전후 입원한 로타바이러스 위장관염 1,165례의 역학 및 임상적 연구, 2006-2013년

Purpose: This study was performed to assess the clinical and epidemiological changes after the introduction of the rotavirus vaccine in Korea, as well as to determine the efficacy of the rotavirus vaccine among hospitalized rotaviral gastroenteritis patients over the past two years. Methods: We analyzed yearly and seasonal patterns of 1,165 inpatients who were hospitalized for rotaviral gastroenteritis under the age of 5 years between 2006 and 2013. We also conducted a survey among 460 gastroenteritis patients who were hospitalized between 2012 and 2013 regarding the rotavirus vaccination and the symptoms of gastroenteritis. Amongthose individuals surveyed, clinical indices were analyzed for 124 patients who were tested positive for the rotavirus antigen. Results: The incidence of Rotaviral gastroenteritis have decreased significantly by year 2010. After the introduction and widespread dissemination of the rotavirus vaccine, the onset of the disease and the seasonal peak have been delayed. Overall, the vaccinated group showed a lower rate of positivity than the unvaccinated group. Among the hospitalized rotaviral gastroenteritis patients, the vaccinated group had a shorter hospitalization period, less severe clinical symptoms of gastroenteritis, and better laboratory test results. Conclusions: After introduction of the rotavirus vaccine in Korea, there were two main trends observed: 1) the overall level of disease incidence was reduced; 2) the severity of rotaviral gastroenteritis cases also decreased. Based on this data, more children should receive vaccination in order to prevent the rotavirus infection and decrease the severity of rotaviral gastroenteritis. 목적: 국내 로타바이러스 백신 도입 전후로 8년간 입원한 로타바이러스 위장관염의 역학 및 임상 양상의 변화를 파악하고자 하였고, 최근 2년간 입원 환자를 대상으로 로타바이러스 예방접종의 효과에 대하여 분석하였다. 방법: 2006년 1월부터 2013년 12월까지 급성 위장관염으로 입원한 5세 미만의 5,697명의 환아 중 로타바이러스 항원 검사에 양성을 보인 1,165명의 연도 및 계절별 추이를 분석하였다. 그리고 2011년 12월부터 2013년 12월까지 급성 위장관염으로 입원한 환아들 중 460명을 대상으로 설문조사를 실시하여 로타바이러스 백신 접종 여부, 접종 횟수, 증상 등에 대하여 파악하였고, 이들 중 로타바이러스 항원검사에서 양성이 확인된 124명을 대상으로 예방접종 시행 여부에 따른 증상 및 검사실 결과를 비교 분석하였다. 결과: 1) 로타바이러스 위장관염의 연령별 분포는 2세 미만의 환아가 전체의 64.5%를 차지하였다. 연도별 로타바이러스 위장관염 발생 수는 2010년부터 급격히 감소하였다. 연도별 월별 분포는 2008년까지는 12월에 발생이 증가하기 시작하여 1-2월에 정점을 이루었으나, 2010년 이후로는 1-2월에 발생이 증가하기 시작하여 3-4월에 정점을 이루는 양상으로, 백신 도입 이후 로타바이러스의 활동의 시작, 계절적 정점이 늦춰지는 양상을 보였다. 2) 로타바이러스 예방접종을 시행하지 않은 환자군에서 로타바이러스 위장관염 발병률이 높았다(P<0.05). Rotarix® 접종군과 RotaTeq®의 로타바이러스 위장관염 발병률은 유의한 차이를 보이지 않았다(P=0.507). 3) 로타바이러스 위장관염 환아 중 예방접종 시행군이 미시행군에 비해 입원기간이 짧았고(P<0.05), 설사, 발열, 구토 등의 증상의 중증도가 더 낮았다(P<0.05). 검사실 소견상 시행군이 미시행군에 비해 혈액 및 소변 검사상 탈수의 정도가 경미하였다(P<0.05). 결론: 국내에 로타바이러스 백신이 도입된 이후 로타바이러스 위장관염의 발병률이 감소하는 경향을 보이고 있으며, 질병의 중증도 또한 낮아졌다. 더 많은 로타바이러스 예방접종의 시행이 이루어지는 것이 로타바이러스 위장관염의 예방 및 질병의 중증도 완화에 도움을 줄 것이다.
