NAMDANG’S THEORY ON THE NATURES OF HUMANS AND NON-HUMAN LIVING BEINGS AND HIS DEVELOPMENT OF ZHU XI’S THEORIES

XING LIJU,LIN XI 계명대학교 한국학연구원 2016 Acta Koreana Vol.19 No.2

This article examines a thesis by Namdang, a Confucian scholar in Chosŏn Korea, on the natures of humans and non-human living beings, using Zhu Xi’s li (理) - qi (氣) theory. Regarding the sameness or difference between li and qi, Zhu Xi formulated different opinions in his early and later life and was also at times inconsistent in his works of a certain period. To a certain extent, Zhu Xi’s thoughts lacked coherence, which led to subsequent debates. In seeking to develop Zhu Xi’s li-qi theory, Namdang put forward his original thesis of Trichotomous Nature, which significantly enriched Zhu Xi’s ideas. The “nature transcending the appearance of things” (K. ch’ohyŏnggi 超形氣) refers to a pure xing (K. sŏng 性; nature), concerned with only li without considering the influence of qi from the perspective of a unitary source (K. irwŏn 一原; one source). At this stage, everything shares the same li and xing. The “nature originated from temperament” (K. in’gijil 因氣質) demonstrates the shared nature for the same species as well as the difference in nature across species, thus being an endowmentdependent li. At this stage, for the same species, they share the same li, qi, and xing, while for varying species, there is a difference in li, qi, and xing. The “nature mixed with temperament” (K. chapkijil 雜氣質) considers the xing of pure qizhi (K. kijil 氣質; physical temperament) in which all creatures differ. It is thus a concept that demonstrates the particularity in all things, with varying differences in li, qi, and xing.

We used computational modeling to investigate the cavitation performance of an aviation fuel pump, and optimize structural parameters using the surrogate-based method. In the numerical simulation, a rotation-curvature correction was adapted to the k-ε turbulence model, and a four-component surrogate fuel was selected to reproduce the physical properties of the China RP-3 kerosene. Then the performance of the aviation fuel pump was predicted. In the optimization, based on the series of the numerical results, Surrogate-based analysis and optimization (SBAO) was used to optimize the structural parameters of the fuel pump (the variation of the outlet blade angle for the inducer △β b1 and the variation of the inlet blade angle for the impeller △β b2 ). The results show that the prediction of cavitation performance agrees well with the experimental data. The results show that cavitation areas are mainly distributed in the inlet of the inducer. The volume of cavities grows with the decreasing NPSHa. The head of the fuel pump has a sudden head-drop when NPSHa ≤ 5.64 m. Furthermore, the surrogate-based approach is available in structural optimization of the fuel pump. The cavitation performance of the optimized pump improved about 22 % with a little drop of head coefficient when △β b1 = 4.33° and △β b2 = 3.24°. The numerical approach employed in this paper can accurately predict the cavitating flow of the high rotating speed fuel pump and the surrogate-based method is available in the structural optimization for a better cavitation performance.

Qigong is on the developmental stage and is expanding to the entire world, while it acknowsedges to the West as a universial method of human healthy-longevity. The conception of health known to thr west is based on the providence of modem civilization and science focusing on the physical practices, however, which usually limit the projected effective execution itself. Recently the eastern method of more effective physical-mental training was explored and by which is replaced for the human-healthy longevity in human life. The western standard form and its criterion was established through researches done by the scheme of biological-medical science, effectively it is revolutionizing forward the the eastern medical science as a formal integration of psychology, physiology and the social environmental elements. According to the eastern thought human life is a unified form of mental and physical integration. In China, the government actually supports in official for the development of qigong so that it is activated, practically suggested and progressed lively throughout the nation. Qigong in Korea is activated today. It will be expanded further from now on. Qigong is considered as a method of natural healing, physical theraphy and healthy longevity while giving attention to a lot of people in our country. As they demand qigong in daily lives, there increased the amount of service institute In our community. However, they are not qualified enough both of the knowledge and practical technique. In a future it may cause social problems and there need countermeasure. Therefore, the government must consider about certain problems such as Qigong clinics and its practicioners, which need to be examined before approval, and should enact the national policy and system so that Qigong in korea can be identifie as physical activity for all, as well as systematically established for a way of national health.

A quantitative weld sizing criterion for fatigue design of load-carrying fillet-welded connections

Xing, S.,Dong, P.,Wang, P. IPC Science and Technology Press ; Elsevier Scienc 2017 International journal of fatigue Vol.101 No.2

Fillet welded connections are most commonly used for construction of engineering structures that are often subjected to various forms of cyclic loading in service. There exist two potential fatigue failure modes, i.e., weld root cracking through weld throat and weld toe cracking into plate thickness. The former should be prevented at design stage through a proper weld sizing. However, due to difficulties in determining stress concentration at weld throat, existing fatigue design rules, particularly on weld sizing, are largely empirical and often result in excessive conservatisms, leading to oversized welds. As structural light weighting becomes increasingly important, there is an increasing demand for more quantitative fatigue-based fillet weld sizing criterion. By taking advantage of a comprehensive set of fatigue test results on load-carrying fillet-welded cruciform joints and associated analytical developments reported by Xing et al. (2016), an analytical weld throat stress model taking into account of weld penetration and joint misalignments is presented in this paper for determining critical weld size beyond which weld throat failure become unlikely. Then, it is shown that a weld sizing criterion can be analytically developed and expressed as a function of weld penetration and joint misalignments, which are shown to agree well with the large amount of test data reported by Xing et al. (2016), including a systematic validation by means of a logistic regression method on the same test data. As a result, the present developments provide both analytical and experimental basis for achieving quantitative weld sizing so that weld throat fatigue failure mode can be effectively prevented with a clearly defined confidence level without the need of over-sizing.

Zhen-xing Xing,Zhuang Huang,Gong-jin Cheng,He Yang,Xiangxin Xue,Guo-dong Zhang 한국화학공학회 2022 Korean Journal of Chemical Engineering Vol.39 No.12

Sea sand vanadia-titania magnetite is difficult to pelletize, and it is difficult for iron and steel enterprises touse it as a raw material for ironmaking. In this paper, the high-temperature physicochemical characteristics and sinteringbehavior of sea sand vanadia-titania magnetite were comprehensively studied and systematically evaluated. Thehigh-temperature metallurgical physicochemical characteristics of different iron ore powders and under different experimentalconditions were studied by the micro-sintering experimental system. The high-temperature sintering indexeswere comprehensively evaluated by the grey correlation analysis, and the influence of sea sand ore on sintering performancewas investigated by sintering pot experiment. The research results show that the high-temperature sinteringcharacteristics of sea sand vanadia-titania magnetite were the worst, and the grey correlation degree was the lowest. The high-temperature sintering characteristics of sintered blocks with sea sand ore were affected by changing the basicityand the addition amount of sea sand ore. When the basicity was 0.8 and the addition amount of sea sand ore was15 wt%, the evaluation index of grey relational analysis was the best. The vertical sintering speed and tumble indexwere slightly reduced by adding sea sand ore, but the sinter yield was improved and the particle size distribution of sinterwas optimized. The experimental results provide a certain data reference for the actual production of sinter with seasand vanadia-titania magnetite.
