This study was designed to investigate the effect of essential amino acids (EAA) and/or non-essential amino acids (NEAA) on the development of parthenogenetic and somatic cell nuclear transfer (SCNT) porcine embryos in vitro. To evaluate the timing of amino acids supplementation, activated oocytes were cultured in NCSU23-PVA with EAA, NEAA or NEAA+EAA (AAs) during specific periods as below: EAA, NEAA or AAs were supplemented during Day 0 to 6 (whole culture period: ALL), Day 2 to Day 6 (post-maternal embryonic transition period: POST-MET), Day 5 to Day 6 (post-compaction period: POST-CMP), Day 0 to Day 2 (pre-maternal embryonic transition period: PRE-MET), or Day 0 to Day 4 (post-compaction period: PRE-CMP). Supplementation of NEAA decreased cleavage rates in PRE-MET and PRE-CMP and also decreased blastocyst rates in POST-CMP. On the other hand, EAA significantly enhanced blastocyst formation rate in POST-MET and no detrimental effect on embryonic development in other groups. Interestingly, NEAA and EAA had synergistic effect when they were supplemented to the medium during whole culture period. Supplementation of AAs also enhanced SCNT porcine embryo development whereas BSA-free medium without AAs could not supported blastocyst formation of SCNT embryos. In conclusion, existence of EAA and NEAA in defined culture medium variously influences the development of parthenogenetic and SCNT porcine embryos, and their positive effect are only occurred when both EAA and NEAA are supplemented to the medium during whole culture period. Additionally, AAs supplementation enhances the blastocyst formation of SCNT porcine embryos when they are cultured in the defined condition.

The purposes of the present work it to study the effect of shear deformation on the static post-buckling response of simply supported functionally graded (FGM) axisymmetric beams based on classical, first-order, and higher-order shear deformation theories. The behavior of postbuckling is introduced based on geometric nonlinearity. The material properties of functionally graded materials (FGM) are assumed to be graded in the thickness direction according to a simple power law distribution in terms of the volume fractions of the constituents. The equations of motion and the boundary conditions derived using Hamilton's principle. This article compares and addresses the efficiency, the applicability, and the limits of classical models, higher order models (CLT, FSDT, and HSDT) for the static post-buckling response of an asymmetrically simply supported FGM beam. The amplitude of the static post-buckling obtained a solving the nonlinear governing equations. The results showing the variation of the maximum post-buckling amplitude with the applied axial load presented, for different theory and different parameters of material and geometry. In conclusion: The shear effect found to have a significant contribution to the post-buckling behaviors of axisymmetric beams. As well as the classical beam theory CBT, underestimate the shear effect compared to higher order shear deformation theories HSDT.

This study examined the effect of sociodrama on children's loneliness and peer relations. Eight children each were assigned to an experimental or a control group. The experimental group enacted sociodrama for six weeks, and the control group did not have any treatment. The first post-test was conducted six weeks after the pre-test; the second post-test was eight weeks after the first post-test. Significant differences between the experimental and control groups were found for loneliness; that is, levels of loneliness and of negative peer relations decreased only in the experimental group. This effect for the experimental group was maintained at the second post-test. It was concluded that sociodrama was effective in reducing loneliness and in improving relationships of a child by improving self-adjustment.

A great number of moment-resisting steel structures collapsed due to ductile crack initiation at welded beam-column connections, followed by explosive brittle fracture in the Kobe (Hyogoken-Nanbu) earthquake in 1995. A series of experimental and numerical studies on cracking behaviors of beam-column connections in steel bridge piers were carried out by the authors' team. This paper aims to study the effect of post weld treatment on cracking behaviors of the connections during a strong earthquake event. Experiments of three specimens with different weld finishes, i.e., as-welded, R-finish, and burr grinding, were conducted. The experimental results indicate that the instants of ductile crack initiation are greatly delayed for the specimens with R-finish and burr grinding finishes compared with the as-welded one. The strain concentration effect in the connection is also greatly reduced in the specimens with post weld treatment compared with the as-welded one, which was also verified in the tests.

본 논문에서는 포스트 텐션으로 보강된 아웃리거 벽체의 부등기둥축소량 저감 효과를 확인하였다. 아웃리거 벽체 시스템을 사용할 경우 콘크리트 부재를 아웃리거로 사용하기 때문에 아웃리거 벽체의 장기거동도 고려해야 한다. 아웃리거 벽체은 깊은 보의 형태로 전단 응력이 지배적이기 때문에 전단 응력을 받는 콘크리트의 장기거동에 대한 이론 연구를 수행하였고 그 결과를 유한요소해석에 적용하였다. 아웃리거의 장기거동 고려 시 부등기둥축소량과 아웃리거에 작용하는 전단력을 확인하였으며, 설계 변수인 아웃리거의 두께를 변경해가며 해석하였다. 해석 결과 부등기둥축소량은 증가하고 아웃리거에 작용하는 전단력은 감소함을 밝혔으며 아웃리거의 강성이 작을수록 그 효과가 크다는 것을 밝혔다. 이후 아웃리거의 장기거동으로 인해 증가한 부등기둥축소량을 감소시키기 위해 포스트 텐션 공법으로 보강하는 방법을 제안하고 그 효과를 확인하였다. 프리스트레스 도입 직후의 프리스트레스 손실과 장기거동에 의한 프리스트레스 손실을 모두 고려하였다. 해석 결과 포스트 텐션 공법의 뛰어난 부등기둥축소량 저감 효과를 확인하였으며, 프리스트레스의 크기가 증가할수록 그 효과가 증가함을 밝혔다.
