Opis:
Embodying an optimistic diplomatic mind in early Joseon Dynasty, haidongzhuguoji written by Shin Suk-ju became a main evidence of Chinese official Ding Yingtai impeaching Joseon in the Jeongyu War occurring in 1597 because of Toyotomi Hideyoshi’s second invasion. Ding Yingtai’s impeachment involved Joseon’s king, Chinese generals in Joseon and officials in Beijing in a political maelstrom, which aroused strong reactions of Joseon king and ministers. In this situation, Joseon’s diplomatic corps were dispatched to Beijing in order to justify and defend. They made preparations and took action zealously, winning the final victory and achieving the goal consequently. However, this book-diplomacy surpassed the problem of justifying a book, thus there were some complicated and subtle meanings in the process. Firstly, This book-diplomacy provided a touchstone of Sino-Korean relationship in Ming Dynasty, explaining the political essence of the relationship. Secondly, This diplomacy resulted from Ming Dynasty’s political fights and calmed down also because of Ming Dynasty’s political fights, intensively showing both Sino-Korean interdependent political fights and each liege fights. Thirdly, The book-diplomacy became an important turning point of the transformation of Joseon’s foreign concept, and Joseon’s “Smaller China” mind began to emphasize excluding barbarians, which made an idealistic preparation for the rising “Smaller China” mind in Qing Dynasty.
Artykuł dotyczy sytuacji politycznej w Korei Jeongyu podczas wojny, która wybuchła w 1597. Korpus dyplomatyczny Korei został wysłany do Pekinu w celu negocjacji i ochrony kraju. Dyplomaci przygotowywali się do rozmów gorliwie, osiągając ostateczne zwycięstwo i zamierzony cel. Książka o dyplomacji haidongzhuguoji zawiera pewne skomplikowane i subtelne znaczenie. Po pierwsze, ta książka dyplomatyczna stanowiła fundament stosunków chińsko-koreańskich za czasów dynastii Ming, wyjaśniając polityczną istotę związków pomiędzy krajami. Po drugie, stosunki dyplomatyczne wynikały z walk politycznych za czasów dynastii Ming, wyraźnie pokazując chińsko-koreańskie współzawodnictwo polityczne. Po trzecie, książka stała się ważnym punktem zwrotnym transformacji koncepcji polityki zagranicznej Korei.
신숙주의 『해동제국기』는 조선 전기의 낙관적 대외관념을 잘 드러낸다. 그러나 도요토미 히데요시가 재차 조선을 침략한 정유재란 시기에 이 책은 명나라 관원 정응태가 조선을 책망하게 되는 주요한 근거가 되며, 이로 인해 조선의 왕과 신하, 정벌군 장군, 북경 관원 모두가 정치적 소용돌이 속으로 휘말려 들어가게 된다. 정응태의 책망은 조선 왕과 신하들의 격렬한 반응을 야기시켰고, 이런 상황 가운데 조선은 변론과 해명을 위해 북경에 사신을 파견하였다. 조선 사신은 북경에서 적극적으로 계획하고 행동하여 결국 외교적 승리를 얻어냈다. 그러나 금번의 서적 외교는 이미 서적에 대해 해명하는 문제를 넘어서고 있었으며, 복잡하면서도 미묘한 의미를 내포하는 것이었다. 첫째, 금번 서적 외교는 중국과 한국이 종주국과 속국의 관계라는 것을 검증하는 데에 있어서 시금석이 되는 것으로, 양국관계에서 정치관계의 본성을 보여주었다. 둘째, 금번 서적 외교는 명조와 조선의 당쟁에서 비롯되었고 마지막에도 명조와 조선의 당쟁으로 말미암아 해결되었는데, 이때 양국 상호간에 얽혀있는 당쟁 및 군신 간의 투쟁이 드러났다. 셋째, 금번 서적 외교는 조선의 대외 관념에 있어서 중요한 전환점이 되었는데, 조선의 ‘소중화’ 의식에서 ‘양이’관념이 강조되기 시작하였고, 이는 청대에 고조하게 되는 조선의 ‘소중화’ 의식의 사상적 준비기가 되었다고 볼 수 있다.

Opis:
Coordinate Measurement Machines (CMMs) have been extensively used in inspecting mechanical parts with higher accuracy. In order to enhance the efficiency and precision of the measurement of aviation engine blades, a sampling method of profile measurement of aviation engine blade based on the firefly algorithm is researched. Then, by comparing with the equal arc-length sampling algorithm (EAS) and the equi-parametric sampling algorithm (EPS) in one simulation, the proposed sampling algorithm shows its better sampling quality than the other two algorithms. Finally, the effectiveness of the algorithm is verified by an experimental example of blade profile. Both simulated and experimental results show that the method proposed in this paper can ensure the measurement accuracy by measuring a smaller number of points.

Opis:
To overcome the disadvantage of decreasing the braking performance of a magnetorheological fluid at high temperatures, a method of combined braking of a shape memory alloy and a magnetorheological fluid is proposed in this paper. The braking torque does not decrease with increasing temperature. Based on the magnetorheological characteristics, the braking torque equation of the magnetorheological fluid is established. Based on the characteristics of the thermal effect, the brake torque equations generated by the shape memory alloy springs are established. This paper provides a basis for the design and manufacture of the shape memory alloy and magnetorheological fluid combined brake system through experiments and theoretical analysis.

Opis:
Topology Optimization and Finite Element Analysis were carried out for reinforced concrete short beams to reveal the force mechanism. The results show that load-transfer paths for the beams can evolve from Bi-directional Evolutionary Structural Optimization and be mechanically supported by the Michell criterion. In the beams, the distribution of a high- -stress compression area appears as a truss under a concentrated load and a tie-arch under a uniform load. The beams do not have much higher bearing capacity but can consume many more materials. Consequently, new design ideas were recommended based on the load transfer paths obtained by Topology Optimization.

Opis:
Purpose: A novel portable system has been used to evaluate spatial knee movement, but its accuracy and repeatability is not known. The aim of this study was to investigate the accuracy and repeatability of the measurement. Methods: Ten healthy participants were included, and the knee motion trajectory during walking were assessed. Six evaluations were conducted (three days by two raters) for each participant. The motion parameters at the key points and the range of motion were statistically analyzed. Intraclass correlation coefficients (ICC), standard error of the measurement (SEM), and the Bland–Altman method were used. Results: For intra-rater repeatability, 1) the ICC values range from 0.75 to 0.9 for rotations; and 0.64 to 0.96 for translations. Among the ICC values, 100% of rotations and 90% of translations were not less than 0.70; 2) among the SEM values, 100% of rotations were not more than 5°, while 73.3% of translations were less than 3 mm. For inter-rater repeatability, 1) the ICC values range from 0.68 to 0.99 for rotations; and 0.57 to 0.93 for translations. Among the ICC values, 95.6% of rotations and 82.2% of translations were not less than 0.70; 2) among the SEM values, 100% of rotations were not more than 5°, and 48.9% of translations were less than 3 mm. The Bland–Altman plots showed good agreement for intra- and inter-repeatability. Conclusions: The results indicated that the accuracy and repeatability of the measurement were acceptable, except for the inter-rater repeatability for translation. This may help researchers and physicians better interpret the measurement data.

Opis:
In this study beneficiation of Ga from alunite ore was investigated. The effects of the calcination temperature, H2SO4 concentration, leaching temperature and liquid-solid ratio on the dissolution characteristic of Ga, K and Al were studied. The results showed that increasing the calcination temperature, H2SO4 concentration and leaching temperature can improve the solubility of K and Al. However, higher H2SO4 concentration and lower leaching temperature can improve the dissolution of Ga, which was beneficial to recovery of Ga. On the basis of the solubility difference in H2SO4, a two-stage process of selective acid leaching and alkali precipitation of Ga was proposed. The concentration of Ga was increased significantly from 54 g/t in alunite ore to 4100 g/t in alkali precipitation product. The major elements of Al and K in alunite were recovered as the alum crystal with a purity of 99.62%.

Opis:
In this work, thermo-mechanically treated 42CrMo steel was subjected to cryogenic treatment conducted by means of orthogonal design method, followed by low-temperature tempering to investigate the effect of different parameters of cryogenic treatment on wear resistance of 42CrMo steel and to optimize parameters of cryogenic treatment for improving wear resistance. The results of hardness test and wear test show that cryogenic treatment significantly improves wear resistance with marginal changes in coefficient of friction and hardness. Specifically, cryogenic temperature has the largest impact on wear resistance of 42CrMo steel, holding time has medium impact, and the parameter of treatment cycles has the least impact. The optimum parameters of cryogenic treatment are -196°C for 12 hours with one cycle for improving wear resistance. The results of scanning electron microscopy (SEM) and X-ray diffractometry (XRD) analysis indicate that marginal changes in hardness and coefficient of friction may be owing to little amount of transformation of retained austenite, and the significant influence of cryogenic treatment on improving wear resistance of 42CrMo steel can be mainly attributed to segregation of carbon atoms promoted by cryogenic treatment resulting in more precipitation of carbides in subsequent tempering.
