This research aims to analyze the fracture coalescence characteristics of brittle sandstone specimen ($80{\times}160{\times}30mm$ in size) containing various flaws (a single fissure, double squares and combined flaws). Using a rock mechanics servo-controlled testing system, the strength and deformation behaviours of sandstone specimen containing various flaws are experimentally investigated. The results show that the crack initiation stress, uniaxial compressive strength and peak axial strain of specimen containing a single fissure are all higher than those containing double squares, while which are higher than those containing combined flaws. For sandstone specimen containing combined flaws, the uniaxial compressive strength of sandstone increase as fissure angle (${\alpha}$) increases from $30^{\circ}$ to $90^{\circ}$, which indicates that the specimens with steeper fissure angles can support higher axial capacity for ${\alpha}$ greater than $30^{\circ}$. In the entire deformation process of flawed sandstone specimen, crack evolution process is discussed detailed using photographic monitoring technique. For the specimen containing a single fissure, tensile wing cracks are first initiated at the upper and under tips of fissure, and anti-tensile cracks and far-field cracks are also observed in the deformation process; moreover anti-tensile cracks usually accompanies with tensile wing cracks. For the specimen containing double squares, tensile cracks are usually initiated from the top and bottom edge of two squares along the direction of axial stress, and in the process of final unstable failure, more vertical splitting failures are observed in the ligament region. When a single fissure and double squares are formed together into combined flaws, the crack coalescence between the fissure tips and double squares plays a significant role for ultimate failure of the specimen containing combined flaws.

This study focused on similarities between modern philosophical Nomadism and the thoughts of Korean people as well as analyzed the correlation between modern Nomad fashion and Korean traditional costumes. This study aims are as follows. First, to establish aesthetic characteristics by examining modern Nomadism and Korean thoughts. Second, draw the principles of design expressions of modern Nomad fashion and Korean traditional costumes. Third, analyze correlations between them. The method of this study was a literature review and an analysis of related photos. The study results are as follows. First, Nomadic aesthetics are characterized by the formation of complex diversity with the variability of fusion and separation through liquidity in an ambiguous boundary; in addition, various possibilities and harmony are the characteristics of Korean aesthetics, held by a holistic thought based on the vision of the universe of Qi (氣). Second, Nomad fashion appeared as variable designs through repetition and the overlapping of forms, and irregular designs were noticed through repetition and the overlapping of circles, quadrangles, and angles in Korean traditional costumes. Third, similarities in the creation of liquidity, variability, and de-territoriality based on modules can be found; in addition, common principles can also be drawn from the appearing design expressions.

This study was performed to investigate the effect of dietary processed sulfur supplementation on water-holding capacity, color, and lipid profiles of pork according to the level of dietary processed sulfur (0%, CON; 0.3%, S). The pigs were slaughtered at an average final weight of 120 kg, and the longissimus dorsi muscles were collected from the carcasses. As results, pork processed with sulfur had significantly higher moisture and ash contents compared to those of CON but lower crude fat, pH, expressible drip, lower redness and yellowness, and greater lightness. Pork processed with sulfur showed significantly lower total lipid content, triglycerides, and atherosclerosis index but significantly higher high-density lipoprotein cholesterol. Feeding processed sulfur significantly lowered myristic acid, heptadecanoic acid, and stearic acid contents, whereas monounsaturated fatty acids and oleic acids were significantly higher compared to those in the CON. Higher amounts of polyunsaturated fatty acids and n-6 fatty acids were observed in the pork processed with sulfur than that of the CON. Therefore, supplementing pigs with dietary sulfur improved nutrient and meat quality.

Apoplexy is a disease of a morbid condition manifested as sudden syncope, unconciousness, distortion of face, hemiplegia and dysphasia, usually seen in the middle-aged. The symptoms and signs before sudden onset are headache, dizziness, numbness of extremities, palpitation, etc. This study was performed to investige causes of disease, therapies and prescriptions by insect medicine through the successive medical literatures, recent chinese medical literatures and chinese medical journals. The results are as follows; 1. The treatment of apoplexy is divided into stage of attack and sequela. In stage of attack, the principal therapies of apoplexy are calming the liver, suppressed Yang, dissipate phlegm and elimination weatness. In sequela, the principal therapies of apoplexy are invigorating Qi, promote blood circulation and dredge collateral. 2. Insects medicine have more strong effect than herbal medicine, because apoplexy is a kind of critically desease. 3. Insects medicine is effective in a convalscent stage and sequela of apoplexy. The proper dosage for stage of attack is a small dose of insects medicine(about 2-4g), increse gradually. In convalscent stage, about 4g, in sequela, patients need a large dose of insects medicine(about 8g). 4. Hirudo used to remove stagnated blood and to disperse swelling for the treatment of severe cases of blood stasis, such as cerebral infarction, sequela of cerebrovascular accident, contused wounds. Lumbricus used to for the treatment of convulsions due to high fever, and for hemiplegia and hypertension.

Objectives : In Pharmaceutical Affairs Act, herbal medicinal preparations are defined as medicines made by Korean medicine principles. But in Act, Korean medicine principles are vague. Thus, there is a request to explain what the Korean medicine principles are. The aim of this study is to suggest implications of Korean medicine principles in definition of herbal medicinal preparations. Methods : With regard for definition of Korean medicine principles, we referred to the domestic and foreign regulations and literature about the history of herbal medicinal preparations. As a result, the meaning of Korean medicine principles was historically examined from various angles. Results : Through this study, we studied the Korean medicine principles from the past medical history. Due to the broad definition of Korean medicinal principles, we tried to extract general ideas of medicine principles first. We also found that we had scientific formulations based on korean medicine principles which could be used in modern society. In the end, we found that numerous medicine principles which include ‘Four qi and five flavors theory’, ‘Processing of medicinals’, ‘Yin and yang theory’, ‘Five phases theory’, ‘Meridian entry of viscera and bowels theory’, ‘Herb Couplet Interaction theory’, ‘Sovereign, minister, assistant and courier theory’, etc. Conclusions : Innumerable principles used from the past existed. These principles were broad and could be used as modern scientific principles. Based on these facts, we illustrated details of Korean medicine principles, hope this principles be widely shared and Korean herbal medicinal preparations be further developed.

A strain of Bacillus thuringiensis that showed signifi­cantly high toxicity to Plutella xylostella was isolated from a dust sample collected from Chinese tobacco warehouse and characterized. The isolate named B. thuringiensis LY-99 was determined to belong to subsp. alesti (H3a3c) by an H antisera agglutination test and produced bipyramidal inclusions. Plasmid and crystal protein patterns of the LY-99 were different from those of the reference strain, subsp. alesti. PCR analysis with specific primers revealed that this isolate contained abundant cry genes including crylAa, crylAc, crylB, crylD, crylE, crylF and cry2 genes, which was absolutely different from cry gene profile of the subsp. alesti. In addition, insecticidal activity of the LY-99 against P. xylostella larvae was about 44 times higher than that of the subsp. alesti.

The stability of deep coal roadways with large sections and thick top coal is a typical challenge in many coal mines in China. The innovative Universal Discrete Element Code (UDEC) trigon block is adopted to create a numerical model based on a case study at the Dongtan coal mine in China to better understand the failure mechanism and stability control mechanism of this kind of roadway. The failure process of an unsupported roadway is simulated, and the results suggest that the deformation of the roof is more serious than that of the sides and floor, especially in the center of the roof. The radial stress that is released is more intense than the tangential stress, while a large zone of relaxation appears around the roadway. The failure process begins from partial failure at roadway corners, and then propagates deeper into the roof and sides, finally resulting in large deformation in the roadway. A combined support system is proposed to support roadways based on an analysis of the simulation results. The numerical simulation and field monitoring suggest that the availability of this support method is feasible both in theory and practice, which can provide helpful references for research on the failure mechanisms and scientific support designing of engineering in deep coal mines.

Objective: To evaluate the efficacy and safety of bevacizumab in the treatment of patients with metastatic colorectal cancer (mCRC). Methods: In a single-center, observational study of 91 Chinese patients with mCRC who received bevacizumab in combination with chemotherapy was conducted. Objective response rates (ORRs), progression-free survival (PFS), overall survival (OS) and adverse events were recorded, and the relationships between various clinical factors and PFS or OS were evaluated by Cox proportional hazards models. Results: Treatment with bevacizumab and chemotherapy was effective and tolerable. Univariate analysis showed that PFS and OS were significantly associated with the Eastern Cooperative Oncology Group performance status (ECOG-PS) score, duration of bevacizumab exposure, and whether chemotherapy was continued after discontinuation of bevacizumab treatment. A multivariate analysis showed that the duration of bevacizumab exposure and whether chemotherapy was continued after discontinuation of bevacizumab were independent prognostic factors for PFS and OS. Conclusion: In Chinese mCRC population, the shorter the duration of exposure to bevacizumab and chemotherapy, the worse the prognosis is.

Background: Soybean oil may protect against cancer of the breast and prostate. It may also exert beneficial influence in combination with other oils. Here, blends (20%, v/v) of sea buckthorn oil (SEBO), camellia oil (CAO), rice bran oil (RBO), sesame oil (SEO) and peanut oil (PEO) with soybean oil (SBO) were formulated. Materials and Methods: Oxidative stability (OS) and radical scavenging activity (RSA) of SBO and blends stored under oxidative conditions ($60^{\circ}C$) for 24 days were studied. By blending with different kinds oils, levels of polyunsaturated fatty acids (PUFA) decreased, while monounsaturated fatty acid (MUFA) content increased. Progression of oxidation was followed by measuring peroxide value (PV), p-anisidine (PAV), conjugated dienes (CD) and conjugated trienes (CT). Results: Inverse relationships were noted between PV and OS at termination of storage. Levels of CD and CT in SBO, and blends, increased with increase in time. The impact of SEO as additives on SBO oxidation was the strongest followed by RBO, CAO, SEBO and PNO. Conclusions: Oxidative stability of oil blends was better than SBO, most likely as a consequence of changes in fatty acids and tocopherols' profile, and minor bioactive lipids found in selected oils. The results suggest that these oil blends could contribute as sources of important antioxidant related to the prevention of chronic diseases associated to oxidative stress, such as in cancer and coronary artery disease.
