This paper examined the cognition for inflatable kayak and life jacket. The assembly, safety, convenience, and carry-on were as proxy for the characteristics of the inflatable kayak. The extrinsic motivation and intrinsic motivation were as proxy for the participation motivation of water-leisure sports. The psychology satisfaction and physical and mental satisfaction were as proxy for the satisfaction of water-leisure sports. Based on the analysis of one thousand five hundred cases, the following results were found. First, the characteristics of the inflatable kayak has a positively significant influence on the participation motivation of water-leisure sports. Second, the characteristics of the life jacket has a positively significant influence on the satisfaction of water leisure sports. Third, the participation motivation of water-leisure sports have a positively significant influence on the participation of water-leisure sports. The main purpose of this study is verification of causal model between the participating motive and participating satisfaction depending on the awareness of kayak type small boats and jackets.

저자들은 심장침범을 동반한 원발성 아밀로이드증이 생긴 52세 남자 환자에서 thalidomide 치료 후 임상적 증상, 심초음파 소견, 검사실 소견이 큰 부작용 없이 현저히 좋아진 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Patients with primary amyloidosis (AL) have poor prognosis with a median survival of one to two years. In patients with symptomatic cardiac involvement, prognosis is even worse with the reported median survival of 6 months. One patient, diagnosed as AL amyloidosis with cardiac involvement, was treated with thalidomide and showed remarkable improvement in functional capacity, cardiac function, and various laboratory parameters without any significant adverse effect and, therefore, we report the case with the review of literatures.(Korean J Med 69:S910-S914, 2005)
H(2,4) 기법을 기반으로 한 저분산 FDTD 기법의 손실 매질의 광대역 해석을 위한 최적화 방법
오일영(Ilyoung Oh) 한국전자파학회 2018 한국전자파학회논문지 Vol.29 No.3
본 논문은 H(2,4) 기법을 기반으로 한 저분산 유한차분 시간영역법(Finite-Difference Time-Domain: FDTD)을 이용하여 상수 도전율과 비유전율을 갖는 유전체의 광대역 전자기 특성을 정확하게 해석하는 방법을 제안했다. 수치분산오차를 최소화하기 위해서 제안한 FDTD 기법에서 이용하는 세 개의 변수의 최적값을 계산하였다. 잘 알려진 정확한 FDTD 기법들과 제안한 FDTD 방법으로 2차원 원형 유전체 실린더의 광대역 산란 문제를 계산하였고, 그 결과를 이론값과 비교하여 제안한 방법의 우수성을 검증하였다. This paper proposed the optimization method of the extremely low numerical-dispersion finite-difference time-domain (ELND-FDTD) method based on the H(2,4) scheme for wideband and extremely accurate electromagnetic properties of lossy material, which has a constant conductivity and relative permittivity. The optimized values of three variables are calculated for the minimum numerical dispersion errors of the proposed FDTD method. The excellent accuracy of the proposed method is verified by comparing the calculated results of three different FDTD methods and the analytical results of the two-dimensional dielectric cylinder scattering problem.

본 논문은 극저분산 유한차분 시간영역(Extremely Low Numerical-Dispersion Finite-Difference Time-Domain, ELNDFDTD) 기법을 이용하여 콘크리트의 전자기 특성을 해석하였다. 콘크리트의 정확한 전자기 특성을 해석하기 위해서 주파수와 콘크리트의 비유전율과 도전율 특성에 맞는 ELND-FDTD의 변수 값(가중값, 비례값)을 계산하였다. 균열이 있는 콘크리트와 균열이 있는 PEC가 겹친 구조에서 콘크리트의 균열(폭, PEC 균열과의 상대적 위치)이 차폐효과에 미치는 영향을 분석했다. 차폐효과는 균열의 폭과 입사각에 따라서 최대 20 ㏈ 차이가 났다. 그리고 균열의 위치와 입사각에 따라서 차폐효과가 최대 22 ㏈의 차이가 남을 확인하였다. The electromagnetic characteristics of concrete using the extremely low numerical dispersion finite-difference time-domain (ELNDFDTD) method have been analyzed. To analyze the electromagnetic properties of concrete accurately, we calculated the weighting factor and scaling factor in the ELND-FDTD according to the frequency, relative permittivity, and conductivity of the concrete. The effects of cracking (width and relative position with perfect electric conductor (PEC) cracking) on shielding effectiveness were analyzed in the overlapping structure of the cracked concrete and cracked PEC. The shielding effectiveness had a variation of 20 ㏈ depending on the width of the crack and the angle of incidence. Furthermore, the shielding effectiveness was found to differ by up to 22 ㏈ depending on the location of the crack and the angle of incidence.
