( Che-ming Yang ),( Keng-hao Kang ),( Kuo-wei Li ),( Hui-jung Wang ),( Ching-ping Hsiao ),( Jyh-jong Liao ),( Yii-wen Pan ) 대한지질공학회 2019 대한지질공학회 학술발표회논문집 Vol.2019 No.2
A deep-seated landslide took place in Luhu, Miao-Li, Taiwan during intermittent rainfall in April 2018; initially, there were successive rock falls and gully erosion then leaded to a deep-seated landslide failure eventually. This study aims to understand the failure mechanism and the process of deep-seated failure. The study site is a steep anaclinal slope consisting of the Miocence Shihti Formation with thick sandstone, interbedded of sandstone and shale. We collected multi-temporal ortho-images and digital elevation (surface) models from 1980 to 2019 for geological investigation, geomorphological interpretation and numerical simulation. The images reveal several slope failures at 1998, 2003, 2005, 2009, 2015, 2017 and 2018 with various volume and failure types. The study area contains three sub-regions: the north, the northwest and the southwest slopes. The slope failure occurred repeatedly inside the north and the northwest slopes in the early stage. Gully erosion in the southwest slope progressed to a landslide on April 5, 2018 first and expanded to cover the deep-seated landslide failure in the northwest slope eventually; the slope failure resulted in a natural dam. After the landslide, several open cracks appeared near to the crown. The estimated maximum thickness, area and volume of the deep-seated landslide are ~60 m, 65,000 m2 and ~2 Mm3, respectively. Based on these results, we also performed a series of numerical simulation using the software RAMMS to interpret the run out and the deposition of this landslide case.

In recent years, human pathogenic microorganisms have developed multiple drug resistance and caused serious nosocomial infections. In this study, we identified four new antimicrobial compounds from the Chinese herbal medicine Illicium verum and assessed their antibacterial efficacies. The supercritical CO2 and ethanol extracts of Illicium verum showed substantial antibacterial activity against 67 clinical drug-resistant isolates, including 27 Acinetobacter baumannii, 20 Pseudomonas aeruginosa, and 20 methicillin-resistant Staphylococcus aureus. The diethyl ether (EE) fraction obtained from partition extraction and supercritical CO2 extracts revealed an antibacterial activity with a minimum inhibitory concentration value of 0.15–0.70mg/mL and 0.11mg/mL, respectively. The EE fraction of I. verum showed synergetic effects with some commercial antibiotics. The antimicrobial mechanism was investigated with killing curves and scanning electron microscopy observation. The chemical components of the extracts were analyzed by spectrophotometry; (E)-anethole, anisyl acetone, anisyl alcohol, and anisyl aldehyde exhibited antibacterial activity against different clinical isolates. These extracts from I. verum can be further developed into antibiotic medicines due to their proven antibacterial activity.

Concurrent involvement of bilateral renal and cerebral arteries, usually incurred as stenosis is rare in childhood-onset Takayasu arteritis (c-TA). We report the case of a 14-year-old girl, with c-TA, presenting with transient ischemic attack after endovascular revascularization for renal artery stenosis and cerebrovascular stroke after surgical revascularization for cerebral artery stenosis associated with childhood-onset moyamoya syndrome. We deem th decrease of blood pressure by endovascular revascularization and improvement of cerebral perfusion by surgical revascularization may have jeopardized the cerebral deep watershed zone to cerebral ischemia followed by cerebral hyperperfusion syndrome and caused transient ischemic attack and cerebrovascular stroke in our patient. Revascularization could be a double-edge sword for c-TA patients presenting with concomitant renal artery stenosis and cerebral artery stenosis, and should be performed with caution. Quantitative analysis of cerebral blood flow by brain magnetic resonance imaging and angiography should be performed within 48 hours after surgical revascularization in c-TA.

In Western countries, breast cancer tends to occur in older postmenopausal women. However, in Asian countries, the proportion of younger premenopausal breast cancer patients is increasing. Increasing evidence suggests that the gut microbiota plays a critical role in breast cancer. However, studies on the gut microbiota in the context of breast cancer have mainly focused on postmenopausal breast cancer. Little is known about the gut microbiota in the context of premenopausal breast cancer. This study aimed to comprehensively explore the gut microbial profiles, diagnostic value, and functional pathways in premenopausal breast cancer patients. Here, we analyzed 267 breast cancer patients with different menopausal statuses and age-matched female controls. The α-diversity was significantly reduced in premenopausal breast cancer patients, and the β-diversity differed significantly between breast cancer patients and controls. By performing multiple analyses and classification, 14 microbial markers were identified in the different menopausal statuses of breast cancer. Bacteroides fragilis was specifically found in young women of premenopausal statuses and Klebsiella pneumoniae in older women of postmenopausal statuses. In addition, menopausal-specific microbial markers could exhibit excellent discriminatory ability in distinguishing breast cancer patients from controls. Finally, the functional pathways differed between breast cancer patients and controls. Our findings provide the first evidence that the gut microbiota in premenopausal breast cancer patients differs from that in postmenopausal breast cancer patients and shed light on menopausal-specific microbial markers for diagnosis and investigation, ultimately providing a noninvasive approach for breast cancer detection and a novel strategy for preventing premenopausal breast cancer.

This paper presents a study to investigate the feasibility of using robotic welding technologies to weld the continuity plate and the column flange plate during manufacturing steel built-up box columns in buildings. Specimens designed to emulate the key components in the steel beam-to-column moment connections for Special moment frame were fabricated and welded using a proposed automated procedure that performs multi-layer, multi-pass welding for thick steel plates. Effects of controlling parameters on robotic welding results that includes the manner of bead stacking, wire feed speed, travel speed, working angle, arc voltage, the path of the welding pass, and the methods to start and finish welding passes were investigated. The quality of the welded products was assessed by visual inspection and ultrasonic testing (UT). Further mechanical tests including tensile tests, bending tests, and cyclic loading tests were carried out on selected welded products that passed the UT examination. The test results indicated that the robotic welds showed no visible damage or cracks, met requirements specified in the AWS specification, and exhibited satisfactory strength and ductility.

Mechanical cutting is very important in many industrial applications. Since mechanical cutting often involves contour following, generally, prior trajectory planning is inevitable. However, in some applications the geometric model of the object for cutting is not available. One possible approach to circumventing this difficulty is to employ a visual servoing approach. As a result, in this paper, an eye-to-hand camera mounted on the ceiling is used to obtain the shape information of the object. Moreover, PH splines are designed to represent the obtained object shape. Based on the obtained PH splines, an interpolator is developed to generate the desired feature command for the Image-Based Visual Servoing (IBVS) structure. Another eye-to-hand camera is placed in a position that can have a full view of the object for cutting so as to provide vision feedback for the IBVS structure. Finally, contouring following experiments of several objects with arbitrary shapes have been conducted to validate the effectiveness of the proposed approach.

Objectives: An Asian Gynecologic Oncology Group phase III randomized trial was conducted to determine whether maintenance chemotherapy could improve progression-free survival (PFS) in stages III/IV ovarian cancer. Methods: Between 2007 and 2014, 45 newly-diagnosed ovarian cancer patients were enrolled after complete remission and randomized (1:1) to arm A (4-weekly carboplatin area under the curve 4 and pegylated liposomal doxorubicin [PLD] 30 mg/m2, n=24) for 6 cycles or arm B (observation, n=21). The primary end-point was PFS. A post hoc translational study was conducted to deep sequence BRCA/homologous recombination deficiency (HRD) genes, because BRCA/HRD mutations (BRCA/HRDm) are known to be associated with better prognosis. Results: Enrollment was slow, accrual was closed when 7+ years had passed. With a median follow-up of 88.9 months, the median PFS was significantly better in arm A (55.5 months) than arm B (9.2 months) (hazard ratio [HR]=0.40; 95% confidence interval [CI]=0.19–0.87; p=0.020), yet the median overall survival was not significantly different in arm A (not reached) than arm B (95.1 months) (p=0.148). Overall grade 3/4 adverse events were more frequent in arm A than arm B (60.9% vs 0.0%) (p<0.001). Quality of life was generally not significantly different. Distribution of BRCA1/2m or BRCA/HRDm was not significantly biased between the two arms. Wild-type BRCA/non-HRD subgroup seemed to fare better with maintenance therapy (HR=0.35; 95% CI=0.11–1.18; p=0.091). Conclusions: Despite limitations in small sample size, it suggests that maintenance carboplatin-PLD chemotherapy could improve PFS in advanced ovarian cancer.

The purpose of this study was to investigate the prevalence of fumonisin contamination in corn and corn-based feeds in Taiwan. A total of 233 samples was collected from 8 feed mill factories located in four different regions in Taiwan. The presence of fumonisin $B_1$ ($FB_1$) and $B_2$ ($FB_2$) was determined by thin layer chromatograph, while the total fumonisin content was determined using immuno-affinity column cleanup and fluorometer quantitation. Our results showed that 55 samples of swine feeds had the highest percentage of incidence of $FB_1$ and $FB_2$ (41.8% and 41.8%, respectively), followed by 66 samples of duck feeds (40.9% and 37.8%). However, the percentage of incidence of $FB_1$ and $FB_2$ was much lower in 43 samples of broiler feeds (23.2% and 13.9%) and 69 samples of corn (17.3% and 10.1%). Corn and duck feeds were found to have a significant higher level of means of total fumonisins ($5.4{\pm}1.5$ and $5.8{\pm}0.6$ ppm, respectively) than swine feeds ($2.9{\pm}0.4$ ppm) and broiler feeds ($3.0{\pm}0.5$ ppm). Comparing fumonisins distribution in different regions, the highest percentage of $FB_1$ incidence (39.2%) was found in the eastern region of Taiwan, and total fumonisins level ($4.5{\pm}0.7$ ppm) was significantly higher than other regions. However, the highest percentage of $FB_2$ incidence (32.0%) was found in the central region of Taiwan. Trimonthly analysis of data showed that both high percentage of $FB_1$ and $FB_2$ incidence (39.3% and 37.7%) and total concentration of fumonisin ($5.7{\pm}0.4$ ppm) were found in the period of Jan. to Mar., The incidence and concentration were significantly higher than other trimothly periods. These results indicate that fumonisin B mycotoxins are both widespread and persistent in feed-grade corn and corn-based feeds in Taiwan.

( Kuo-wei Li ),( Chien-yu Lin ),( Jyh-jong Liao ),( Yi-wen Pan ),( Keng-hao Kang ),( Che-ming Yang ) 대한지질공학회 2019 대한지질공학회 학술발표회논문집 Vol.2019 No.2
This study produced an inventory of the 2,523 potential large-scale landslide areas (PLSLAs) in southern Taiwan. These PLSLAs were delineated using LiDAR DEM of 1m resolution after the 2009 Typhoon Morakot by other institutes. Using the inventory, we conducted a statistical analysis of the important geologic and geomorphologic factors possibly related to a PLSLA. The statistical analyses reveal that, among the 2,523 PLSLAs, (1) 82% of elevation are between 750 and 2,750 m, (2) 79% of the area are between 10 and 40 hectares, (3) 76% of the slope height are between 200 and 600 m, (4) 86% of the slope are between 25 and 40 degrees and (5) 83 percent of stream order are less than 3. Rock formations of these PLSLAs range from Oligocene to Miocene; 67% of the strata are slate, and 12% are interbedded of sandstone and shale. This study selected 24 medium to high risk cases of the 2,523 PLSLAs, and interpreted the micro-geomorphological features from 1m LiDAR DEM. The following three patterns were present: (1) PLSLA with clear features of gravitational slope deformation in slope height more than 500 m condition, (2) PLSLA with the relic of paleo landslides induced by gravitational buckling, toppling, or plane sliding, (3) PLSLA with river bank erosion on slope toe and head-cut erosion induced by gully development. Based on statistics, the stream order of the PLSLAs with gravitational slope deformation usually would exceed 3; 83% of PLSLAs are the areas also with paleo large-scale landslide.
