18 types of Rehmanniae Radix Preparatas, 9 types(from 1st to 9th steamed) of sun-dried and 9 types of oven-dried, were prepared, and the carbohydrates of Rehmanniae Radix Preparata was analized by HPLC. The results were : 1. The Rehmanniae Radix had several carbohydrates such as rhamnose, fucose, glucose, galactose, raffinose and stachyose, and the content of stachyose was the 71.5% of total carbohydrates. 2. In the course of the processing, the oligosaccharides, such as stachyose and rafiinose, were paridly degraded to melibiose and sucrose at first and second processing step. 3. Sucrose and melibiose gradually degraded with each additional processing. 4. The monosaccharides, such as rhamnose, fructose, glucose and galactose, was continuously degraded during the processing. These results suggested that Rehmannia radix preparata sufficiently developed only during second processing.

<P>Phase transitions in correlated materials can be manipulated at the nanoscale to yield emergent functional properties, promising new paradigms for nanoelectronics and nanophotonics. Vanadium dioxide (VO2), an archetypal correlated material, exhibits a metal insulator transition (MIT) above room temperature. At the thicknesses required for heterostructure applications, such as an optical modulator discussed here, the strain state of VO2 largely determines the MIT dynamics critical to the device performance. We develop an approach to control the MIT dynamics in epitaxial VO2 films by employing an intermediate template layer with large lattice mismatch to relieve the interfacial lattice constraints, contrary to conventional thin film epitaxy that favors lattice match between the substrate and the growing film. A combination of phase-field simulation, in situ real-time nanoscale imaging, and electrical measurements reveals robust undisturbed MIT dynamics even at preexisting structural domain boundaries and significantly sharpened MIT in the templated VO2 films. Utilizing the sharp MIT, we demonstrate a fast, electrically switchable optical waveguide. This study offers unconventional design principles for heteroepitaxial correlated materials, as well as novel insight into their nanoscale phase transitions.</P>

Shih-Chen Lee,Hwai-En Tseng,Chien-Cheng Chang,Yu-Ming Huang 한국정밀공학회 2020 International Journal of Precision Engineering and Vol.21 No.4
In addition to garbage sorting and resource recycling, green design should be a fundamental method for solving environmentalproblems, and design for disassembly is an important foundation of green design. This study focuses on providingquantitative assessment methods for designers’ reference. This study proposes interactive genetic algorithms to solve theproblem of disassembly sequence planning. First, the disassembly factor is measured by the fuzzy scoring procedure method,and then the genetic algorithm is used to select the optimal sequence. With the penalty value provided from the process, areference is provided for the revised design. Finally, examples are discussed to demonstrate that the proposed approach isa feasible method.

Objective: Predicting disease relapse and early intervention could reduce symptom severity. We attempted to identify potential indicators that predict the duration to next admission for an acute affective episode in patients with bipolar I disorder. Methods: We mathematically defined the duration to next psychiatric admission and performed single-variate regressions using historical data of 101 patients with bipolar I disorder to screen for potential variables for further multivariate regressions. Results: Age of onset, total psychiatric admissions, length of lithium use, and carbamazepine use during the psychiatric hospitalization contributed to the next psychiatric admission duration positively. The all-in-one found that hyperlipidemia during the psychiatric hospitalization demonstrated a negative contribution to the duration to next psychiatric admission; the last duration to psychiatric admission, lithium and carbamazepine uses during the psychiatric hospitalization, and heart rate on the discharge day positively contributed to the duration to next admission. Conclusion: We identified essential variables that may predict the duration of bipolar I patients’ next psychiatric admission. The correlation of a faster heartbeat and a normal lipid profile in delaying the next onset highlights the importance of managing these parameters when treating bipolar I disorder.

Objective: Weight gain is an important risk factor for morbidity and mortality among patients with schizophrenia. We speculated that positive symptoms, related to dopaminergic hyperactivity and altered mesolimbic function, are associated with weight gain. Methods: Twenty-two antipsychotic-naïve, first-episode patients with schizophrenia were enrolled. The Positive and Negative Syndrome Scale was completed at enrollment and follow-up. Body mass index (BMI) was also measured. Results: The increase in BMI, after 6.04 ± 2.16 years of follow-up, was associated with positive symptoms, but not negative symptoms, before treatment with antipsychotics in antipsychotic-naïve patients with schizophrenia. Conclusion: This finding implied that dopaminergic hyperactivity could be an important factor to predict the treatment outcome. Body weight control is important for the health management of patients with schizophrenia with more severe positive symptoms.

Two experiments were conducted to investigate the effect of dietary glutamine (Gln) supplement on the performance and villus morphology of weaned pigs. In Exp. 1, 48 pigs were fed diets supplemented with 0, 0.5, 1.0, or 1.5% Gln for 28 days. Dietary Gln supplemented levels did not influence performance and plasma Gln concentration of weaned pigs. In Exp. 2, 48 weaned pigs were fed the same treatment diets of Exp. 1 for 7 or 14 days. Dietary Gln supplement reduced the ratio of small intestine weight to empty carcass weight at d 14 postweaning. However, the villus height and villus height/crypt depth ratio at the duodenum were increased. IgA and protein in the bile from d 7 and d 14 postweaning were higher in the pigs fed the diet supplemented with 0.5% Gln. Plasma IgA concentration was not influenced by dietary Gln levels. In conclusion, dietary Gln supplement might benefit the development of the small intestine and bile IgA production in weaned pigs.

<P>We investigated the relationship between carotid artery blood pressure (BP) and distal pulse volume waveforms (PVRs) via subject-specific mathematical modeling. We conceived three physical models to define the relationship: a tube-load model augmented with a gain (TLG), Voigt (TLV), and standard linear solid (TLS) models. We compared these models using PVRs measured via BP cuffs at an upper arm and an ankle as well as carotid artery tonometry waveform collected from 133 subjects. At both upper arm and ankle, PVR was related to carotid artery tonometry by TLV and TLS models better than by TLG model; when root-mean-squared over all the subjects, the systolic and diastolic BP errors between measured carotid artery tonometry waveform and the one estimated from distal PVR reduced from 4.3 mmHg and 4.6 mmHg (TLG) to 1.1 mmHg and 1.0 mmHg (TLS) for the upper arm (<I>p</I> < 0.0167), and from 2.1 mmHg and 1.7 mmHg (TLG) to 2.1 mmHg and 1.5 mmHg (TLV) for the ankle. Further, TLV and TLS models exhibited superior Akaike's Information Criterion (AIC) in both locations than TLG model. However, the difference between TLG versus TLV and TLS models associated with the ankle was not large. Therefore, the relationship of central arterial BP to arm PVR arises from both wave reflection and viscoelasticity while the relationship to ankle PVR mainly arises from wave reflection. These findings may imply that an effective subject-specific transfer function for estimating accurate central arterial BP from an arm PVR should account for the impact of viscoelasticity.</P>
Impact Assessments of High Oil Prices on the Agro-Food System and the Role of Bioenergy Crops
Lee, Duu-Hwa,Lin, Hsin-Chun,Chang, Ching-Cheng,Hsu, Shih-Hsun,Chen, Chi-Chun,Sun, Jenny Chin-Hwa Korean Resource Economics Association 2007 자원·환경경제연구 Vol.16 No.3
In this study, multi-sectoral partial equilibrium and computable general equilibrium models of Taiwan are used to investigate the direct and indirect effects of energy price increases on overall economies and agro-food sector in Taiwan. The results suggest that agricultural prices, production cost would increase between 0.27% to 1.88%, and a reduction in GDP around 0.39% to 0.54 %. The negative impact on livestock sector is slightly higher than that on the crop sector. Negative impacts are also observed in the employment and wages. The rising oil price has the potential to discourage production of energy-intensive activity because of the possibility of substitution and adaptations. The growth rate of real GDP will shrink by 0.64% to 1.06% and CPI will increase by 1.17% to 1,95%. Both the agriculture and non-agricultural sector also respond by raising output prices by 0.80% to 1.33%. The rising international oil price has urged the government to take policy actions like using alternative fuels such as biodiesel, bioethanol, and adopting measures to cut down on energy consumptions mainly in transportation sectors in response to public concern over economic shocks.
