Objective: This study was performed to validate the autonomous maximal smile (AMS) as a new reference for evaluating dental and gingival exposure. Methods: Digital video clips of 100 volunteers showing posed smiles and AMS at different verbal directives were recorded for evaluation a total of three times at 1-week intervals. Lip-teeth relationship width (LTRW) and buccal corridor width (BCW) were measured. LTRW represented the vertical distance between the inferior border of the upper vermilion and the edge of the maxillary central incisors. Intraclass correlation coefficients (ICCs) for reproducibility, and the m-value (minimum number of repeated measurements required for an ICC level over 0.75), were calculated. Results: LTRW and BCW of the AMS were 1.41 and 2.04 mm, respectively, greater than those of the posed smile (p < 0.05), indicating significantly larger dental and gingival exposure in the AMS. The reproducibility of the AMS (0.74 to 0.77) was excellent, and higher than that of the posed smile (0.62 to 0.65), which had fair-to-good reproducibility. Moreover, the m-value of the AMS (0.88 to 1.05) was lower than that of the posed smile (1.59 to 1.85). Conclusions: Compared to the posed smile, the AMS shows significantly larger LTRW and BCW, with significantly higher reproducibility. The AMS might serve as an adjunctive reference, in addition to the posed smile, in orthodontic and other dentomaxillofacial treatments.

Objective: Early environmental enrichment in life can improve cognition in animals. The effect of prenatal auditory stimulation on learning ability and fear level in chick embryos remained unexplored. Therefore, this study investigated the effect of prenatal auditory stimulation on the learning ability and fear level of chicks. Methods: A total of 450 fertilized eggs were randomly divided into 5 groups, including control group (C), low-sound intensity music group (LM), low-sound intensity noise group (LN), high-sound intensity noise group (HN) and high-sound intensity music group (HM). From the 10th day of embryonic development until hatching, group LM and group LN received 65 to 75 dB of music and noise stimulation. Group HN and group HM received 85 to 95 dB of noise and music stimulation, and group C received no additional sound. At the end of incubation, the one-trial passive avoidance learning (PAL) task and tonic immobility (TI) tests were carried out, and the serum corticosterone (CORT) and serotonin (5-HT) concentrations were determined. Results: The results showed that compared with the group C, 65 to 75 dB of music and noise stimulation did not affect the PAL avoidance rate (p>0.05), duration of TI (p>0.05) and the concentration of CORT (p>0.05) and 5-HT (p>0.05) in chicks. However, 85 to 95 dB of music and noise stimulation could reduce duration of TI (p<0.05) and the concentration of CORT (p<0.05), but no significant effect was observed on the concentration of 5-HT (p>0.05) and PAL avoidance rate (p>0.05). Conclusion: Therefore, the prenatal auditory stimulation of 85 to 95 dB can effectively reduce the fear level of chicks while it does not affect the learning ability.

Oxidation of coal under mild conditions is effective not only to understand the macromolecular network structure of coal but also to produce useful chemicals, allowing more efficient application of coal resources. In this work, the mild oxidation of Zhundong subbituminous coal (ZS) by Fe2+/H2O2 system was carried out under various conditions, including [Fe2+]/[H2O2] molar ratio, temperature, H2O2 concentration and oxidation time. The liquid oxidation products were analyzed using gas chromatography/mass spectrometry (GC/MS), and the chemical structure changes were studied using Fourier transform infrared spectroscopy (FTIR). The results suggest that the oxidation efficiency of ZS with H2O2 is enhanced with the aid of Fe2+. The optimum conditions were determined to be [Fe2+]/[H2O2] molar ratio of 0.00453, H2O2 concentration of 3mol/L, 60 oC and 4 h according to the oxidation conversion rate. In total, 25 compounds were identified, which could be categorized as six group components. Most of them are valuedadded chemicals, and the content of benzene carboxylic acids is the highest among them, making up 29.99% of all group components in total relative content (TRC). -CH2- should be primary bridge connecting the aromatic rings, and alkylene chains linking three aromatic rings are abundant in ZS.

제11회 한,중 형법 국제 학술심포지엄 : 당대 중국 회사범죄 논쟁문제의 연구

쟈오빙즈 ( Bing Zhi Zhao ),허우쓰와이 ( Shuai Hou ) 한국비교형사법학회 2013 비교형사법연구 Vol.15 No.2

회사범죄는 중국 단위(單位)범죄의 중대한 유형으로 실무에서 가장 흔하게 볼 수 있는 단위범죄의 형식이다. 회사범죄에 대한 정의는 회사주체, 회사의지와 범죄행위 3가지 기본요소를 포함하여야 한다. 또한 고의와 과실 두 가지 죄과(罪過)형식도 포함하여야 한다. 회사가 범죄를 성립하는데 있어서는 자연인 범죄와는 다른 성립조건이 있어야 한다. 회사범죄의 귀책근거를 확립하여 회사의 독립적인 범죄주체의 지위를 중시하며 회사제도 등에서 회사범죄의 특징적인 요인 및 형벌목적을 구현하는 데서 출발하여 회사범죄 귀책근거의 정당성과 합리성을 고찰해야 한다. 일부 고의범죄의 법정범죄 종류 외에 회사도 과실 범죄와 일부 자연범죄의 종류를 실시할 수 있는데 회사과실범죄는 업무과실과 감독관리과실 두 가지 형식을 지닌다. 회사범죄의 책임자에 대한 판단은 신분 특징과 행위특징 두 가진 측면을 근거로 하여야 하며 또한 다른 죄과형식과 회사제도를 고려하여야 한다. 단지 한 사람의 자연인을 주주로 하는 1인 회사가 실시한 범죄행위는 회사범죄가 아닌 자연인 범죄를 성립하여야 한다. 민법의 법인인격 부인제도를 이용하여 1인의 회사범죄 주체자격을 부인하는 것은 부적절하며 응당 형법 중의 회사범죄 성립조건으로 그 자격을 부인하여야 한다. 한 명의 자연인 주주인 1인회사는 “회사 의지 지배 하에서 실시한 범죄행위”라는 이 조건에 부합하지 않기 때문이다. The corporation crime is an important and common type of the unit crime in China. The concept of corporation crime should include the corporation subject,the corporation will and the corporation action. And the concept should include intentional crime and negligent crime. How can a corporation`s action can be judged as a crime that depends on the 30 article in criminal law of China and the details about different charges. The theory basis of the corporation`s criminal responsibility should regard corporation as a relatively independent subject. In additions, different company systems and the expected aim of penalty for company crime are also the essential elements should be considered. The corporation can commit both intentional crimes and negligent crimes. And the latter include the vocational negligence and the supervision management negligence. What kind of natural person should take criminal responsibility of their corporation`s crime actions? That depends on the natural person`s status trait and action trait. The intentional crime and negligence crime, corporations of different forms also have different natural persons to take criminal responsibility. According to Chinese Company Law, one-man corporation is a kind of new corporation form according to Chinese Company law. If the one-man corporation which has only a natural stockholder commit a crime, the stockholder should take the criminal responsibility instead of The one-man corporation`s crime act is the natural stockholder`s crime act actually.

Whole Exome Sequencing in the Male Breast Cancer with Prolactinoma: A Case Report and Literature Review

Shuai Hao,Miao Huang,Wuguo Tian,Yi Chen,Jianjie Zhao,Donglin Luo 한국유방암학회 2020 Journal of breast cancer Vol.23 No.6

Male breast cancer (MBC) is rare and accounts for approximately 1% of all breast cancer cases worldwide. Previous studies have suggested that several factors significantly increase the risk of MBC. Prolactinoma has the highest incidence rate among patients with functional pituitary tumors. However, whether prolactinoma is involved in the onset and progression of breast cancer remains unclear. To date, there are only five case reports globally on MBC with concurrent prolactinoma. We hereby describe the first case of MBC with prolactinoma in China. We also explored the patient's genetic profile using whole exome sequencing. Our findings may help advance our understanding of the molecular pathogenesis of MBC. Further molecular analyses of such cases are warranted to improve auxiliary molecular diagnostic methods and targeted therapy for MBC.

Shuai Hao,Wuguo Tian,Jianjie Zhao,Yi Chen,Xiaohua Zhang,Bo Gao,Yujun He,Donglin Luo 한국유방암학회 2020 Journal of breast cancer Vol.23 No.4

Purpose: Real-time detection and intervention can be used as potential measures to markedly decrease breast cancer mortality. Assessment of circulating tumor DNA (ctDNA) may offer great benefits for the management of breast cancer over time. However, the use of ctDNA to predict the effectiveness of neoadjuvant treatment and recurrence of breast cancer has rarely been studied. Methods: We prospectively recruited 31 breast cancer patients with 4 subtypes. Three time points were set in this study, including before any therapy (C1), during surgery (T), and six months after surgery (C2). We collected peripheral blood samples from all 31 patients at C1, tumor tissue from all 31 patients at T, and peripheral blood samples from 25 patients at C2. Targeted 727-gene panel sequencing was performed on ctDNA from all blood samples and tissue DNA from all tissue samples. Somatic mutations were detected and analyzed using a reference standard pipeline. Statistical analysis was performed to identify possible associations between ctDNA profiles and clinical outcomes. Results: In total, we detected 159, 271, and 70 somatic mutations in 30 C1 samples, 31 T samples, and 12 C2 samples, respectively. We identified specific genes, such as PIK3CA, TP53, and KMT2C, which were highly mutated in the tissue samples. Furthermore, mutated KMT2C observed in ctDNA of the C2 samples may be an indicator of breast cancer recurrence. Conclusion: Our study highlights the potential of ctDNA analysis at different timepoints for assessing tumor progression and treatment effectiveness, as well as prediction of breast cancer recurrence.

Fabrication Tolerance of InGaAsP/InP-Air-Aperture Micropillar Cavities as 1.55-μm Quantum Dot Single-Photon Sources

Shuai Huang,Xiumin Xie,Qiang Xu,Xinhua Zhao,Guangwei Deng,Qiang Zhou,You Wang,Hai-Zhi Song 한국광학회 2020 Current Optics and Photonics Vol.4 No.6

A practical single photon source for fiber-based quantum information processing is still lacking. As a possible 1.55-µm quantum-dot single photon source, an InGaAsP/InP-air-aperture micropillar cavity is investigated in terms of fabrication tolerance. By properly modeling the processing uncertainty in layer thickness, layer diameter, surface roughness and the cavity shape distortion, the fabrication imperfection effects on the cavity quality are simulated using a finite-difference time-domain method. It turns out that, the cavity quality is not significantly changing with the processing precision, indicating the robustness against the imperfection of the fabrication processing. Under thickness error of ±2 nm, diameter uncertainty of ±2%, surface roughness of ±2.5 nm, and sidewall inclination of 0.5°, which are all readily available in current material and device fabrication techniques, the cavity quality remains good enough to form highly efficient and coherent 1.55-µm single photon sources. It is thus implied that a quantum dot contained InGaAsP/InP-air-aperture micropillar cavity is prospectively a practical candidate for single photon sources applied in a fiber-based quantum information network.

Zhao Jinbiao,Liu Xuzhou,Zhang Yi,Liu Ling,Wang Junjun,Zhang Shuai 아세아·태평양축산학회 2020 Animal Bioscience Vol.33 No.12

Objective: The study was conducted to determine the effects of body weight (BW) and fiber sources on nutrient digestibility, fiber fermentation and short chain fatty acids (SCFA) concentration in different intestinal segments of growing pigs fed high-fiber diets. Methods: Nine barrows with initial BW of 25.17±0.73 kg and 9 barrows with initial BW of 63.47±2.18 kg were allotted to a duplicate 9×2 Youden Square design with 3 dietary treatments and 2 periods. The dietary treatments were formulated with 3 different high-fiber ingredients: corn bran, sugar beet pulp, and soybean hulls, respectively. Each diet was fed to 3 barrows with different stage of BW in each period. Results: There were no differences in the apparent ileal digestibility (AID) of most nutrients between pigs at different BW stages. Pigs at 60 kg had greater (p<0.05) apparent total tract digestibility (ATTD) of total dietary fiber (TDF), soluble dietary fiber (SDF) and insoluble dietary fiber (IDF), and had greater (p<0.05) hindgut disappearance of IDF and cellulose than pigs at 25 kg. The acetate, propionate and total SCFA concentrations in ileal digesta and feces of pigs at 60 kg were greater (p<0.05) than those of pigs at 25 kg. In addition, fiber sources affected (p<0.05) the AID of gross energy (GE), organic matter (OM), ether extract (EE), crude protein, SDF and hemicellulose, the hindgut disappearance and ATTD of dietary fiber components, the lactate and propionate concentrations in ileal digesta and the butyrate, valerate and total SCFA concentrations in feces. There were interactions (p<0.05) between BW and fiber sources on the AID of GE, OM, EE, SDF, hemicellulose, the ATTD of EE, TDF, and IDF, and the hindgut disappearance of SDF and hemicellulose. Conclusion: Increasing BW mainly improved the digestibility of dietary fiber fractions, and the dietary fiber sources influenced the digestibility of almost all the dietary nutrients in growing pigs.
