This article investigates the concept of the xing(性) used by Hu Hong. Hu Hong's philosophical system considered to top priority for xing is called xingbunlun(性本論), and he suggested the characteristics of xing as follows. First, Hu Hong regarded xing as the fundamental of whole world and related to the specific individual things, so he constructed the concept of xing in the perspective of ontology. Namely while xing is ti(體) the root of all the world, it is the realization of the uniqueness of the individual things. Also he considered xing which of the ontological aspect developed various psychological aspect contained xin (心), qing(情), yu(欲), etc. Seond, As Hu Hong regulated that wei fa(未發) is xing and yi fa(已發) is xin, he defined the ideal relation between xing and xin as xingtixinyong(性體心用). And he considered that the sage and the ordinary peoples are equal in the xing's aspect of wei fa, but they are not equal in ability of the xin in the aspect of wei fa. Hu Hong thought that the only sage realized the ideal relation between xing and xin in this world, because he keep his mind silent. So Hu Hong suggested the possibility of moral cultivation to the ordinary peoples, expressing that human nature realized the function of the mind(成性), in order that they realized ideal relation by following ren(仁). Third, unlike the traditional notion, Hu Hong understood the meaning of xing in the aspect of ontology. He interpreted the shan(善) of xingshan(性善) as the meaning of exclamation, which implied that "the innate goodness of human nature(性善)" meant "Human nature is good." Because Hu Hong thought that the meaning of xing transcended the relative concept of good and evil, and accepted the whole world affirmatively. In the opinion of Hu Hong, as the concept of xing had two ways of intentionality; likes and dislikes(好惡), things formed relationship with other in this world. Then the concept of good and evil of the ethical value judgement occurred.

In this paper, the writer examined the procedural changes of Zhuzi(朱子)'s theory of ZhongHe(中和), and also investigated the evaluations thereof made by the later generations. In the stage of ZhongHeJiuShuo(中和舊說), Zhuzi(朱子) ignored the theory of Lidong(李?), which was traditional theory argued by DaoNam School(道南學派). He met Zhangshi(張?) of HuXiang School(湖湘學派) and followed the school's philosophy, 'XianChaShiHouHanYang(先察識後涵養)', meaning what you should do first prior to making great efforts in self-cultivation is to examine the past, when desiring to know yourself. Even though Zhuzi(朱子) had learned the method of moral cultivation from Lidong(李?), he was fascinated by such method of moral cultivation as 'XianChaShiHouHanYang(先察識後涵養)' advocated by HuXiang School(湖湘學派) through discussion with Zhangshi(張?). This tells that he only recognized the fact that there were no achievements WeiFa(未發), but only the achievements YiFa(已發). In the stage of ZhongHeXinShuo(中和新說), he realized the mistakes committed in the time of ZhongHeJiuShuo(中和舊說), and put emphasis upon the achievements in the time WeiFa(未發). Zhuzi(朱子) had explained the relationships among mind, nature, and emotional bond as by his theory, 'XinTongXingQing(心統性情)', meaning that mind controls humans' original nature. Also he followed self-cultivation of Respect, no longer believing the Huhong(胡宏)'s XianChaShiHouHanYang(先察識後涵養). Such a method of self-cultivation means that his method of moral cultivation centered on the achievements YiFa(已發), which was originated from HuXiang School(湖湘學派), had been changed into the method of moral cultivation with a focus on the achievements WeiFa(未發), which was theory argued by DaoNam School(道南學派). However, Zhuzi(朱子)'s theory of ZhongHe(中和) that had seemed perfect began to be discussed and polished again during Joseon Period through the debates between Ligu(栗谷) and Niuxi(牛溪) in the 16th century, and through the debates between Youan(尤庵) and Yuxuan(寓軒) in the 17th century, also through the HuLuoLunZheng(湖洛論爭) represented by Nantang(南塘) and Weiyan(巍巖). Since Zhuzi(朱子)'s theory of ZhongHe(中和) had some flaws, it had to put through such debates as mentioned above. Those debates were generated because imperfections were found in the theory of ZhongHe(中和) by Zhuzi(朱子).

To improve the fermentation quality of silage and reduce the nutrients loss of raw materials during the ensiling process, silage additives are widely used. The effect of additives on silage is also affected by the species of crop. Therefore, this study was designed to explore the effects of formic acid (FA) and lactic acid bacterial inoculant on the quality of main summer crop silage. The experiment was consisted on split-plot design with three replications. The experiment used the main summer forage crops of proso millet ("Geumsilchal"), silage corn ("Gwangpyeongok"), and a sorghum-sudangrass hybrid ("Turbo-gold"). Treatments included silage with Lactic acid bacterial Inoculant (Lactobacillus plantarum [LP], 1.0 × 106 CFU/g fresh matter), with FA (98%, 5 mL/kg), and a control (C, without additive). All silages were stored for 60 days after preparation. All additives significantly increased the crude protein content and in vitro dry matter digestibility (IVDMD) of the silages and also reduced the content of ammonia nitrogen (NH3-N) and pH. Corn had the highest content of IVDMD, total digestible nutrients and relative feed value among silages. Compared with the control, irrespective of whether FA or LP was added, the water soluble carbohydrate (WSC) of three crops was largely preserved and the WSC content in the proso millet treated with FA was the highest. The treatment of LP significantly increased the lactic acid content of the all silage, while the use of FA significantly increased the content of acetic acid (p < 0.05). The highest count of lactic acid bacteria (LAB) was detected in the LP treatment of corn. In all FA treatment groups, the total microorganism and mold numbers were significantly lower than those of the control and LP groups (p < 0.05). In conclusion, both additives improved the fermentation quality and nutritional composition of the main summer forage crops. The application of FA effectively inhibited the fermentation of the three crops, whereas LAB promoted fermentation. So, both FA and LP can improve the quality of various species of silage.

Background: Our objective was to evaluate the MTHFR C677T-A1298C polymorphisms in patients with breast cancer and in individuals with no history of cancer, to compare the levels of genetic damage and apoptosis under folic acid (FA) deficiency between patients and controls, and to assess associations with breast cancer. Methods: Genetic damage was marked by micronucleated binucleated cells (MNBN) and apoptosis was estimated by cytokinesis-block micronucleus assay (CBMN). PCR-RFLP molecular analysis was carried out. Results: The results showed significant associations between the MTHFR 677TT or the combined MTHFR C677T-A1298C and breast cancer risk (OR = 2.51, CI = 0.85 to 7.37, p = 0.08; OR = 4.11, CI = 0.78 to 21.8, p < 0.001). The MNBN from the combined MTHFR C677T-A1298C was higher and the apoptosis was lower than that of the single variants (p < 0.05). At 15 to 60 nmol/L FA, the MNBN in cases with the TTAC genotype was higher than controls (p < 0.05), whereas no significant difference in apoptosis was found between the cases and controls after excluding the genetic background. Conclusions: Associations between the combined MTHFR C677T-A1298C polymorphism and breast cancer are possible from this study. A dose of 120 nmol/L FA could enhance apoptosis in cases with MTHFR C677T-A1298C. Breast cancer individuals with the TTAC genotype may be more sensitive to the genotoxic effects of FA deficiency than controls.

Conventional concrete needs some improvement in the mechanical properties, which can be obtained by different admixtures. However, making concrete samples costume always time and money. In this paper, different types of hybrid algorithms are applied to develop predictive models for forecasting compressive strength (CS) of concretes containing metakaolin (MK) and fly ash (FA). In this regard, three different algorithms have been used, namely multilayer perceptron (MLP), radial basis function (RBF), and support vector machine (SVR), to predict CS of concretes by considering most influencers input variables. These algorithms integrated with the grey wolf optimization (GWO) algorithm to increase the model's accuracy in predicting (GWMLP, GWRBF, and GWSVR). The proposed MLP models were implemented and evaluated in three different layers, wherein each layer, GWO, fitted the best neuron number of the hidden layer. Correspondingly, the key parameters of the SVR model are identified using the GWO method. Also, the optimization algorithm determines the hidden neurons' number and the spread value to set the RBF structure. The results show that the developed models all provide accurate predictions of the CS of concrete incorporating MK and FA with R² larger than 0.9972 and 0.9976 in the learning and testing stage, respectively. Regarding GWMLP models, the GWMLP1 model outperforms other GWMLP networks. All in all, GWSVR has the worst performance with the lowest indices, while the highest score belongs to GWRBF.

Cables are critical components of cable-stayed bridges. A structural health monitoring system provides real-time cable tension recording for cable health monitoring. However, the measurement data involve multiple sources of variability, i.e., varying environmental and operational factors, which increase the complexity of cable condition monitoring. In this study, a one-class classification method is developed for cable condition assessment using Bayesian factor analysis (FA). The single-peaked vehicle-induced cable tension is assumed to be relevant to vehicle positions and weights. The Bayesian FA is adopted to establish the correlation model between cable tensions and vehicles. Vehicle weights are assumed to be latent variables and the influences of different transverse positions are quantified by coefficient parameters. The Bayesian theorem is employed to estimate the parameters and variables automatically, and the damage index is defined on the basis of the well-trained model. The proposed method is applied to one cable-stayed bridge for cable damage detection. Significant deviations of the damage indices of Cable SJS11 were observed, indicating a damaged condition in 2011. This study develops a novel method to evaluate the health condition of individual cable using the FA in the Bayesian framework. Only vehicle-induced cable tensions are used and there is no need to monitor the vehicles. The entire process, including the data pre-processing, model training and damage index calculation of one cable, takes only 35 s, which is highly efficient.

Objective: To evaluate the application of laplacian-regularized mean apparent propagator (MAPL)-MRI to brain glioma-induced corticospinal tract (CST) injury. Materials and Methods: This study included 20 patients with glioma adjacent to the CST pathway who had undergone structural and diffusion MRI. The entire CSTs of the affected and healthy sides were reconstructed, and the peritumoral CSTs were manually segmented. The morphological characteristics of the CST (track number, average length, volume, displacement of the affected CST) were examined and the diffusion parameter values, including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), radial diffusivity (RD), mean squared displacement (MSD), q-space inverse variance (QIV), return-to-origin probability (RTOP), return-to-axis probabilities (RTAP), and return-to-plane probabilities (RTPP) along the entire and peritumoral CSTs, were calculated. The entire and peritumoral CST characteristics of the affected and healthy sides as well as those relative CST characteristics of the patients with motor weakness and normal motor function were compared. Results: The track number, volume, MD, RD, MSD, QIV, RTAP, RTOP, and RTPP of the entire and peritumoral CSTs changed significantly for the affected side, whereas the AD and FA changed significantly only in the peritumoral CST (p < 0.05). In patients with motor weakness, the relative MSD of the entire CST, QIV of the entire and peritumoral CSTs, and the AD, MD, RD of the peritumoral CST were significantly higher, whereas the RTPP of the entire and peritumoral CSTs and the RTOP of the peritumoral CST were significantly lower than those in patients with normal motor function (p < 0.05 for all). In contrast, no significant changes were found in the CST morphological characteristics, FA, or RTAP (p > 0.05 for all). Conclusion: MAPL-MRI is an effective approach for evaluating microstructural changes after CST injury. Its sensitivity may improve when using the peritumoral CST features.
