宋元时期, 游戱的风气较为盛行。本人想通過考察'關撲'而要了解這時期的民間遊戲文化. 尤其賭博遊戲文化. 所以, 本論文主要針對《燕靑博魚》第二節中的有關'博魚'部分探討. 考察當中除了元雜劇《燕靑博魚》這一作品分析之外, 以宋孟元老的《東京夢華錄》爲主要參考資料. 通過燕靑'博魚'有現實感豐富的具體內容, 能够瞭解到當時節日游戱民俗的一種'關撲'盛行的風氣與城市社會經濟的種種面貌.

The steel-concrete double composite girder in the negative flexural region combines an additional concrete slab to the steel bottom flange to prevent the local steel buckling, however, the additional concrete slab may lower down the neutral axis of the composite section, which is a sensitive factor to the tensile stress restraint on the concrete deck. This is actually of great importance to the structural rationality and durability, but has not been investigated in detail yet. In this case, a series of 5.5 m-long composite girder specimens were tested by negative bending, among which the bottom slab configuration and the longitudinal reinforcement ratio in the concrete deck were the parameters. Furthermore, an analytical study concerning about the influence of bottom concrete slab thickness on the cracking and sectional bending-carrying capacity were carried out. The test results showed that the additional concrete at the bottom improved the composite sectional bending stiffness and bending-carrying capacity, whereas its effect on the concrete crack distribution was not obvious. According to the analytical study, the additional concrete slab at the bottom with an equivalent thickness to the concrete deck slab may provide the best contributions to the improvements of crack initiation bending moment and the sectional bending-carrying capacity. This can be applied for the design practice.

In this study, a series of flexible neutron/gamma shielding composites are fabricated through the doping of Gd₂O₃ into the matrix of SEBS with (M_Gd2O3: M_SEBS) % from 5% to 100%. Neutron transmittance test shows an exponential attenuation with the increase of areal density of Gd, in which the transmittance T ranges from 59.1440% to 35.3026%, with standard deviation less than 2.2743%, mass attenuation coefficient 𝜇_m from 0.3194 cm²/g to 0.4999 cm²/g, and half value layer-HVL value from 2.4530 mm to 1.1313 mm. Shielding efficiency of the Gd₂O₃/SEBS composites is basically improved in comparison with that of B₄C/SEBS. The transmittance T, mass/linear attenuation coefficient 𝜇_m and 𝜇, HVL and effective atomic number Z_eff for the shielding of γ rays (39 keV, 59 keV and 122 keV) are measured and calculated with XCOM as well as MCX programs. Finally, plots of the three dimensional relationships between transmittance, doping amount and thickness are provided to the guidance for engineering shielding design. In summary, the Gd₂O₃/SEBS composite is proved to be an effective flexible neutron/low energy γ rays shielding material, which could be of potential applications in the field of nuclear technology and nuclear engineering.

본 연구의 목적은 조선 학자에 의해 편성된 『주자대전(朱子大全)』 선집서를 대상으로 간행과 구성, 편성 방식, 수용 양상에 대하여 분석한 것이다. 16세기에 거질의 『주자대전(朱子大全)』이 간행되자 이를 수용하기 위한 방편으로 선집서의 편성과 간행, 학습이 이어졌다. 『주자대전(朱子大全)』 선집서는 조선 전기에 6종, 조선 후기에 7종 등 모두 13종이 간행되었다. 선집서의 편성은 이황의 『주자서절요』를 기점으로 정경세의 『주문작해』로 보완되고, 송시열의 『절작통편(보유)』로 종합되는 흐름을 보였다. 『주자대전(朱子大全)』에는 시(詩)를 제외하면, 3,645편의 작품이 있으며, 그 가운데 13종의 선집서에서 모두 1,734편이 선정되었다. 누적 선정 횟수가 높은 작품의 주제는 국왕의 덕목과 자세, 정책 제안, 인재 등용, 신하의 의무, 역사 인물 평가 기준, 금과의 화친 반대와 영토 회복, 학문 토론 등이다. 이 연구는 조선시대 외국 서적의 수용과 주자 문집의 작품 수용 연구분야에 의미가 있을 것으로 기대한다.
