Ling-Ling Xie,Li-Qin You,Xiao-Yu Cao,Chao-Feng Zhang,Da-Wei Song,Ling-Bo Qu 대한금속·재료학회 2012 ELECTRONIC MATERIALS LETTERS Vol.8 No.4

Co3(PO4)2-coated LiV3O8 has been successfully synthesized and used as positive material for rechargeable lithium batteries by a facile liquid phase method. The as-prepared powders were characterized by x-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), and the galvanostatic discharge/charge experiments. As-prepared Co3(PO4)2-coated LiV3O8 forms a good layered structure with a poor cyrstallinity. SEM reveals that Co3(PO4)2-coated LiV3O8 has uniform particle distribution and reduced particle size when compared with bare one. The Co3(PO4)2 coating layer is about 33 - 59 nm forming a continuous lumps attached to LiV3O8 particle surface. Co3(PO4)2-coated LiV3O8 electrode shows increased capacity and more stable cycling. The first and 35th discharge capacities of the Co3(PO4)2-coated LiV3O8electrode are 322.8 mAh g−1 and 235.7 mAh g−1 in the range of 4.0 - 1.8 V at a current rate of 30 mA g−1, respectively. The improved electrochemical performance is assigned to the greatly reduced LiV3O8 particle with uniform morphology. Co3(PO4)2-coating further benefits the phase transitions of LiV3O8 during discharge/charge while preventing parasite reactions between electrode surface and electrolyte.

Purpose The prognosis of nasopharyngeal carcinoma (NPC) patients with parotid lymph node (PLN) metastasis remains unclear. This study was performed to investigate the prognostic significance and optimal staging category of PLN metastasis and develop a nomogram for estimating individual risk. Materials and Methods Clinical data of 7,084 non-metastatic NPC patients were retrospectively reviewed. Overall survival (OS) was the primary endpoint. A nomogram was established based on the Cox proportional hazards regression model. The accuracy and calibration ability of this nomogram was evaluated by C-index and calibration curves with bootstrap validation. Results Totally, 164/7,084 NPC patients (2.3%) presented with PLNs. Multivariate analyses showed that PLN metastasis was a negative prognostic factor for OS, progression-free survival (PFS), distant metastasis-free survival (DMFS), and locoregional relapse-free survival (LRFS). Patients with PLN metastasis had a worse prognosis than N3 disease. Five independent prognostic factors were included in the nomogram, which showed a C-index of 0.743. The calibration curves for probability of 3- and 5-year OS indicated satisfactory agreement between nomogram-based prediction and actual observation. All results were confirmed in the validation cohort. Conclusion NPC patient with PLN metastasis had poorer survival outcome (OS, PFS, DMFS, and LRFS) than N3 disease. We developed a nomogram to provide individual prediction of OS for patients with PLN metastasis.

A Difference Expansion Based Reversible Data Hiding Algorithm Using Edge-Oriented Prediction

Wen-Chao Yang,Ling-Hwei Chen,Chang-Hsing Lee 보안공학연구지원센터 2014 International Journal of Security and Its Applicat Vol.8 No.6

In this paper, a difference expansion based reversible data hiding approach which achieves the low distortion requirement under the same embedding capacity is proposed. An edge-oriented prediction method and a modified overflow/underflow prevention method are proposed to achieve the requirement. For each pixel, the prediction method uses edge information to get a better predicted value in an attempt to reduce the image distortion. Experimental results have demonstrated that the proposed reversible data hiding method yields lower distortion than several well-known expansion-based reversible data hiding methods.

Undisclosed Desire and Hidden Anxiety: A Rereading of the Gender Relations in E. M. Forster`s Howards End

( Mei Ling Chao ) 한국영미문학페미니즘학회 2012 영미문학페미니즘 Vol.20 No.3

In Howards End (1910), E. M. Forster carries out a highly nuanced exploration of gender relations to highlight the conflicting ideas of liberalism and materialism of the upper-middle classes in England in the years before World War I. Such readings are predicated on classical gender opposition. However, clear-cut gender division seems unsettling and hence somewhat crude because the reader is repeatedly baffled by the novel`s out-of-character gender performances, which not only defy but transcend established gender expectations. In Howards End, all major characters seem to be overshadowed by some kind of performative failure in their inability to fully realize gender roles as well as to adequately fulfill gender expectations. This paper aims to verify through textual evidence whether or not performative failure actually manifests hidden anxieties concealed behind a novel written immediately preceding Forster`s final confirmation of his own sexual identity. It also attempts to show how the anxieties have been disguised, transformed, or overlaid in more public statements about conventional issues of courtship and marriage in the novel. In other words, Howards End may prove to be only deceptively conventional and a key to unfolding Foster`s secret desire.

長沙吴簡 중의 簽署·省校 및 勾畫符號의 釋例

凌文超(Ling, Wen-chao),송진영(번역자) 한국목간학회 2016 목간과 문자 Vol.0 No.17

본문에서는 簿書를 해석하는 범주에서 吳簡 중 보이는 簽署·省校 및 勾畫符號(약호略號)에 대해 살펴보고자 한다. ‘調布入受莂’에 서명된 ‘祁’는 아마도 臨湘 侯國 丞 祁의 친필 서명일 것이다. ‘庫入受莂’ 중 ‘丞弁關’은 佐吏가 대신 서명한 것으로 보이며, 이 두 가지는 모두 권위성과 효력을 지니고 있다. ‘户品出錢簡’에서 (臨湘)侯相의 아래 부분에 적힌 校記 ‘ ’는 臨湘 侯相 ‘管君’ 혹은 屬吏가 ‘户品出錢簿’를 감사한 후 서명한 것이고, ‘已核’(이미 감사됨을 의미함)이라고 한다. ‘襍錢領出用餘見簿’에서 흔히 보이는 ‘朱筆涂痕’(빨간색 긴 선)은 장부의 유통내역 대조가 끝났다는 약호이고, 校記 ‘中’의 역할과 기본적으로 비슷하며 ‘符合·正確(부합함과 정확함)’을 의미한다. Some examples of the signatures, checking marks and sketched symbols in the Wu Slips unearthed at Zoumalou are studied from the structure of the registers. The signature “Qi(祁)” in some registers of cloth entered and received at the treasury should be the autograph of Qi(祁), who was the assistant of the chancellor of the Linxiang marquisate, and the signature “Cheng Bian Guan(丞弁關)” in some entered and received registers at the treasury should be the allograph of staff member. Whether autograph “Qi(祁)”, or allograph “Cheng Bian Guan(丞弁關)” were authoritative and effective. The checking mark “ ” in some registers of cash payment of households of the three grades should be the official comment written by the chancellor of the Linxiang marquisate “GuanJun(管君)” or a staff member after checking the registers. The checking mark “ ” meant that has been checked and correct. The “red paint mark” (red long lines) in the registers of various types cash received, spent and remaining should be the sketched symbol which was used to check the account transfer. The role of this sketched symbol was the same as the checking mark “zhong(中)”, which were meant consistent and corrent.

Objectives: Falls is a risk factor for fracture. The FRAX® predicts fractures. Whether the FRAX® is associated with fall in both gender is inconclusive. The aim of our study is to evaluate the association between FRAX scores and falls. Methods: The cross-sectional study set from 2009 to 2010 included 1200 community-dwelling people who were systematically sampled in central Taiwan. The 1200 participants (men: 524; women: 676; ?40 years old) completed questionnaires about socioeconomic status; lifestyle; medical and fall history were completed. FRAX scores with and without bone mineral density (BMD) were calculated by using the Taiwan calculator. Results: A total of 19.8% participants fell down. Binary regression models showed that diabetes mellitus history (OR: 1.61; 95% CI: 1.03e2.52), the FRAX without BMD in a continuous major score (OR: 1.06; 95% CI: 1.03e1.09), continuous hip score (OR: 1.11; 95% CI: 1.05e1.16), categorical major score ? 10% (OR: 1.81; 95% CI: 1.25e2.61), and categorical hip score ? 3% (OR: 1.80; 95% CI: 1.30e2.50) were independent risk factors for falls. FRAX with BMD in a continuous major score (OR: 1.04; 95% CI: 1.02e1.06), continuous hip score (OR: 1.06; 95% CI: 1.02e1.09), categorical major score ? 10% (OR: 1.52; 95% CI: 1.09e2.12), and categorical hip score ? 3% (OR: 1.53; 95% CI: 1.13e2.09) were also independent risk factors. Conclusions: We concluded that FRAX® scores with and without BMD were unanimously correlated with falls in community-dwelling middleaged and elderly males and females.

Weather Recognition Based on 3C-CNN

( Ling Tan ),( Dawei Xuan ),( Jingming Xia ),( Chao Wang ) 한국인터넷정보학회 2020 KSII Transactions on Internet and Information Syst Vol.14 No.8

Human activities are often affected by weather conditions. Automatic weather recognition is meaningful to traffic alerting, driving assistance, and intelligent traffic. With the boost of deep learning and AI, deep convolutional neural networks (CNN) are utilized to identify weather situations. In this paper, a three-channel convolutional neural network (3C-CNN) model is proposed on the basis of ResNet50.The model extracts global weather features from the whole image through the ResNet50 branch, and extracts the sky and ground features from the top and bottom regions by two CNN5 branches. Then the global features and the local features are merged by the Concat function. Finally, the weather image is classified by Softmax classifier and the identification result is output. In addition, a medium-scale dataset containing 6,185 outdoor weather images named WeatherDataset-6 is established. 3C-CNN is used to train and test both on the Two-class Weather Images and WeatherDataset-6. The experimental results show that 3C-CNN achieves best on both datasets, with the average recognition accuracy up to 94.35% and 95.81% respectively, which is superior to other classic convolutional neural networks such as AlexNet, VGG16, and ResNet50. It is prospected that our method can also work well for images taken at night with further improvement.
