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.

The aim of this study was to investigate the effects of tectorigenin on chemically induced liver fibrosis in rats. Liver fibrosis was induced in rats with carbon tetrachloride, a diet high in fat, cholesterol and alcohol in the drinking water. Our results indicate that tectorigenin treatment significantly inhibited the increases in the activities of alanine aminotransferase (ALT),aspartate aminotransferase (AST) and the increases in the serum levels of hyaluronate (HA), laminin (LN) and procollagen III N-terminal peptide (PIIIP); tectorigenin treatment also significantly inhibited the increases in the amount of collagen in the livers of the fibrogenic rats. Chemically induced liver fibrosis caused a drop in the serum albumin concentration and a decrease in the ratio of albumin to globulin (A/G). Tectorigenin caused a remarkable increase at a dose of 30 mg/kg, but only a slight increase at the lower doses. Tectorigenin was also able to inhibit the increase in the liver lipid peroxidation (LPO), as well as the decrease in the activities of liver superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), caused by liver fibrosis. In addition, we present a related metabolic profile determined, using a 1H NMR spectroscopy and multivariate pattern recognition techniques. The results were consistent with the pathological examination, liver function analysis and liver fibrosis marker analysis. Furthermore, tectorigenin does not cause acute toxicity.

Control-Oriented Modeling of a Three-Dimensional Hypersonic Vehicle with Rigid/Flexible Coupling

Xi-bin Zhang,Yu-mei Ding,Zhen-xing Zhang 한국항공우주학회 2022 International Journal of Aeronautical and Space Sc Vol.23 No.2

Modeling for a hypersonic vehicle is a great challenging task due to its tightly integrated airframe/propulsion system and flexible structure. A three-dimensional, six-degree-of-freedom, physics-based hypersonic vehicle model is being established that can capture the real physical characteristics for control studies. Flexible effects, aerodynamic loads and viscous effects are calculated using or combining variation method, shock/expansion theory and Eckert’s reference temperature method. Based on curve fit approximation of the forces and moments of the vehicle, a control-oriented six-degree-of-freedom model is then developed. The simulations illustrate that the surrogate model contain aerodynamic/structure/propulsion interactions of the vehicle, and can support designing of the model-based control.

Review : Present Situation and Prospects of Sericulture in China

( Xing Jia Shen ),( Xia Yu Ye ),( Xi Jie Guo ) 한국잠사학회 2006 International Journal of Industrial Entomology Vol.13 No.2

Since 1970, China has become the biggest cocoon producer in the world, and made the highest historical record of cocoon output for 759,800 tons in 1995. However, in 1996 cocoon production reduced sharply to 470,900 tons. After a ten-year adjustment and reform, sericultural areas have shifted from developed regions to developing regions and from the east to the west. From 2000, the cocoon output has started to increase restoringly. By 2004 it recovered to 547,091 tons. With the development of market economy, sericulture management has been changed, including mulberry fields concentrated to the specializated households and cooperatives, cocoons produced in larger scale instead of individuals, Silkworm egg producing enterprises gradually changed into non-governmental joint-stock ones. The mechanism of market cocoon price has been gradually established. The management model of combination of trade, industry and agriculture is pushing and improving. It is the fruit of modern science and technology, especially sericultural basic research, that provides China`s sericulture with the opportunity and vital force. China`s sericulture, therefore, will continue to develop steadily in future.

Determining the Optimal Dose Prescription for the Planning Target Volume with Stereotactic Body Radiotherapy for Non-Small Cell Lung Cancer Patients

Liu, Xi-Jun,Lin, Xiu-Tong,Yin, Yong,Chen, Jin-Hu,Xing, Li-Gang,Yu, Jin-Ming Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.5

Objective: The aim of this study was to determine a method of dose prescription that minimizes normal tissue irradiation outside the planning target volume (PTV) during stereotactic body radiotherapy (SBRT) for patients with non-small cell lung cancer. Methods: Previous research and patients with typical T1 lung tumors with peripheral lesions in the lung were selected for analysis. A PTV and several organs at risk (OARs) were constructed for the dose calculated; six treatment plans employing intensity modulated radiotherapy (IMRT) were produced, in which the dose was prescribed to encompass the PTV, with the prescription isodose level (PIL) set at 50, 60, 70, 80, 90 or 95% of the isocenter dose. Additionally, four OARs around the PTV were constructed to evaluate the dose received in adjacent tissues. Results: The use of higher PILs for SBRT resulted in improved sparing of OARs, with the exception of the volume of lung treated with a lower dose. Conclusions: The use of lower PILs is likely to create significant inhomogeneity of the dose delivered to the target, which may be beneficial for the control of tumors with poor conformity indices.

Wei-Xi Shen,Guang-Hua Li,Yu-Jia Li,Peng-Fei Zhang,Jia-Xing Yu,Di Shang,Qiu-Shi Wang 대한암예방학회 2023 Journal of cancer prevention Vol.28 No.4

This study aimed to investigate the prognostic significance of tumor mutation burden (TMB) among patients with non-small cell lung cancer (NSCLC) who received platinum-based adjuvant chemotherapy. Tumor tissue specimens after surgical resection were collected for DNA extraction. Somatic mutation detection and TMB analysis were conducted using next-generation sequencing (NGS). Recurrence status of the patients was assessed in the hospital during the adjuvant chemotherapy period, and long-term survival data of patients were obtained by telephone follow-up. Univariate analysis between TMB status and prognosis was carried out by survival analysis. A retrospective review of 78 patients with non-squamous NSCLC who received platinum-based adjuvant chemotherapy showed a median disease-free survival of 3.6 years and median overall survival (OS) of 5.3 years. NGS analysis exhibited that the most common mutated somatic genes among the 78 patients were tumor suppressor protein p53 (TP53), epidermal growth factor receptor, low-density lipoprotein receptor related protein 1B, DNA methyltransferase 3 alpha and FAT atypical cadherin 3, and their prevalence was 56.4%, 48.7%, 37.2%, 30.7%, and 25.6%, respectively. TMB status was divided into TMB-L (≤ 4.5/Mb) and TMB-H (> 4.5/Mb) based on the median TMB threshold. Relevance of TMB to prognosis suggested that the median OS of patients with TMB-L was significantly longer than that of patients with TMB-H (NR vs. 4.6, P = 0.014). Higher TMB status conferred a worse implication on OS among patients with non-squamous NSCLC who received platinum-based adjuvant chemotherapy.

Relationship between the methylenetetrahydrofolate reductase (MTHFR) rs1801133 SNP and serum homocysteine levels of Zhuang hypertensive patients in the central region of Guangxi

Background The relationship between the methylenetetrahydrofolate reductase (MTHFR) single nucleotide polymorphism (SNP) and serum homocysteine (Hcy) levels or H-type hypertension in different populations is inconsistent. This study aimed to explore the association between the MTHFR rs1801133 SNP and serum Hcy levels of Zhuang hypertensive patients in the central region of Guangxi. Methods A total of 606 Zhuang inpatients with essential hypertension were recruited in our hospital from August 2016 to December 2018. The patients were divided into H-type hypertension (Hcy > 10 μmol/L, n = 528) and non–Htype hypertension (Hcy ≤ 10 μmol/L, n = 78) groups. At the same time, an age- and sex-matched group of 379 subjects with normal physical examination in our hospital were selected as the control group. Blood biochemical measurements and genotyping of the MTHFR rs1801133 SNP were performed. Results The prevalence of H-type hypertension was 87.13%. The levels of serum Hcy in patients with hypertension were higher than those in control group (14.20 ± 5.78 μmol/L vs. 11.97 ± 5.39 μmol/L, P < 0.001), especially in patients with H-type hypertension (15.08 ± 5.65 μmol/L, P < 0.001). The frequencies of TT genotype (22.73%) and T allele (46.21%) in patients with H-type hypertension were significantly higher than those in control group (11.35% and 30.47%, respectively) and non–H-type hypertension group (10.26% and 28.85%, respectively; P < 0.001 for all). Multivariate linear regression analysis showed that serum Hcy levels were significantly correlated with creatinine, lowdensity lipoprotein cholesterol, endogenous creatinine clearance rate, and the MTHFR rs1801133 genotypes in control group, while serum Hcy levels were significantly correlated with creatinine, triglyceride, low-density lipoprotein cholesterol, endogenous creatinine clearance rate, glycosylated hemoglobin, and the MTHFR rs1801133 genotypes in H-type hypertension group (P < 0.05–0.001). Serum Hcy levels in the T allele carriers were higher than those in the T allele noncarriers in both H-type hypertension and control groups. Conclusions There was closely related between the MTHFR rs1801133 SNP and serum Hcy levels in Zhuang patients with H-type hypertension in the central region of Guangxi. The MTHFR SNP may be an important reason for the increase of serum Hcy levels in Zhuang patients with H-type hypertension in this region.

A Parallel Method of Deep Packet Inspection based on Message-Passing Interface

Jia-xing Qu,Guo-yin Zhang,Xi-zhong Wang,Jia-hui Liu,Da-hua Song 보안공학연구지원센터 2015 International Journal of Security and Its Applicat Vol.9 No.12

With the increasing number of cores in multicore processors, it is challenging task how to take advantage of powerful parallel computing for the deep packet inspection. This paper introduces the deep packet inspection with a parallel method which exploits the message-passing interface (MPI). The parallel procedure includes the master thread and the slave thread. The master assigns the data packet to the slave. The slave executes the string matching with rules for inspecting. Both the master and the slave communicate by using MPI functions. The experimental results show that the parallel method is suitable for the trend of the increasing number of cores in multicore processors. Moreover, when the number of threads is equal to the number of cores in multicore processors, the performance arrives at the maximum throughput.
