1927년부터 1936년까지 연속간행물에 실린 딩링 관련 언급은 주로 딩링 실종사건에 관한 것이며 이 사건을 계기로 국공양당의 여론 대결이 벌어졌다. 이번 여론 대결은 국민당의 공신력 훼손과 좌익 문인에 대한 비밀처형, 언론 봉쇄 등 ‘전과'로 인해 초반부터 대결에서 불리한 위치에 처하였다. 또한 국민당은 딩링의 스캔들을 조작하는데 주력했지만 공산당은 딩링의 작품이나 생애에 대한 전문적인 평가 글을 발표한 것을 통하여 딩링의 혁명적 여걸 이미지를 구축하였다. 딩링은 작품 활동 초기부터 자신의 작품과 상관없이 과대평가되거나 과소평가되었으며, 본고는 국공양당의 경합 속에서 형성된 딩링 언론에 나타난 딩링 이미지 구축을 통하여 이것의 이유를 고찰하고자 한다. The commentaries about Ding Ling published in newspapers and magazines from 1927 to 1936 mainly revolved around the disappearance of Ding Ling, and the Kuomintang and the Communist Party launched a confrontation in the field of public opinion by virtue of Ding Ling’s disappearance. In this confrontation, due to the damage to the Kuomintang’s credibility, as well as its record of arresting left-wing literati, carrying out secret executions, and blocking of speech, etc., they were at a disadvantage from the very beginning of the duel. Moreover, the Kuomintang used the main public opinion offensive to create Ding Ling's affairs. When Ding Ling's disappearance was first reported, there were scandals such as Ding Ling living together with Ma Shaowu and being in love with many literati.

The seal structure is an efficient way to reduce leakage and improve rotor stability in gas turbine machines. Various seals have been proposed to achieve this goal in the last century. Labyrinth seals (LS), one of those seals, are widely used in industry due to their relatively simple structure. This paper studied whirl radius dependence of hole diaphragm labyrinth seal (HDLS), which designed by adding hole-diaphragms in LS. A series of working conditions of whirl frequencies, rotation speeds and whirl radius rates were considered in simulations. The characteristic parameters in the rotordynamic model of the seal rotor system were calculated. The results show that a better stiffness performance of HDLS was obtained than those of LS and diaphragm labyrinth seal (DLS) on the small whirl radius. The effective damping of HDLS is slightly better than that of LS but moderately worse than that of DLS at higher rotation speeds. The adaptability under multiple working conditions of HDLS represents its feasibility, which can be used in seal-rotor systems. The analysis of the new type of labyrinth seal proposed in this paper confirmed some advantages in gas turbine and steam turbine applications and is worthy of further study.

"The deactivation mechanism of Pd@CN catalyst in the liquid-phase phenol hydrogenation was investigated by designing many experiments. The phenol conversion decreased by 40% through five reaction cycles. The catalyst deactivation could be mainly ascribed to the surface coverage and the pore blockage with organic matters including cyclohexanone and other derivatives. Three after-treatment methods, i.e., water washing, drying and storing in water, strongly affected the catalytic activity of Pd@CN. After the reaction, by storing the recovered Pd@CN catalyst in water, its catalytic performance could be maintained. These findings provide in-depth insights on the deactivation and recycling of Pd@CN catalyst."

Background and Aims: Hepatitis B virus (HBV) reactivation was reported to be induced by transcatheter arterial chemoembolization (TACE) in HBV-related hepatocellular carcinonma (HCC) patients with a high incidence. The effective strategy to reduce hepatitis flares due to HBV reactivation in this specific group of patients was limited to lamivudine. This retrospective study was aimed to investigate the efficacy of prophylactic entecavir in HCC patients receiving TACE. Methods: A consecutive series of 191 HBV-related HCC patients receiving TACE were analyzed including 44 patients received prophylactic entecavir. Virologic events, defined as an increase in serum HBV DNA level to more than 1 log10 copies/ml higher than nadir the level, and hepatitis flares due to HBV reactivation were the main endpoints. Results: Patients with or without prophylactic were similar in host factors and the majorities of characteristics regarding to tumor factors, HBV status, liver function and LMR. Notably, cycles of TACE were parallel between the groups. Ten (22.7%) patients receiving prophylactic entecavir reached virologic response. The patients receiving prophylactic entecavir presented significantly reduced virologic events (6.8% vs 54.4%, p=0.000) and hepatitis flares due to HBV reactivation (0.0% vs 11.6%, p=0.039) compared with patients without prophylaxis. Kaplan-Meier analysis illustrated that the patients in the entecavir group presented significantly improved virologic events free survival (p=0.000) and hepatitis flare free survival (p=0.017). Female and Eastern Cooperative Oncology Group (ECOG) performance status 2 was the only significant predictors for virological events in patients without prophylactic antiviral. Rescue antiviral therapy did not reduce the incidence of hepatitis flares due to HBV reactivation. Conclusion: Prophylactic entecavir presented promising efficacy in HBV-related cancer patients receiving TACE. Lower performance status and female gender might be the predictors for HBV reactivation in these patients.

Background: This retrospective study was aimed to investigate the efficacy of prophylactic agents in hepatocellular carcinoma (HCC) patients receiving TACE and compare the difference between lamivudine and entecavir. Materials and Methods: A consecutive series of 203 HBV-related HCC patients receiving TACE were analyzed including 91 patients given prophylactic agents. Virologic events, defined as an increase in serum HBV DNA level to more than 1 log10 IU/ml higher than the nadir level, hepatitis flares due to HBV reactivation and progression free survival (PFS) were the main endpoints. Results: Some 48 (69.6%) reached virologic response. Prophylaxis significantly reduced virologic events (8.8% vs 58.0%, p=0.000) and hepatitis flares (1.1% vs 13.4%, p=0.001). Patients presenting undetectable HBV DNA levels displayed a significantly improved PFS as compared to those who never achieved undetectable HBV DNA. Prophylaxis and e-antigen positivity were the only significant variables associated with virologic events. In addition, prophylaxis was the only independent protective factor for hepatitis flares. Liver cirrhosis, more cycles of TACE, HBV DNA negativity, a lower Cancer of the Liver Italian Program score, non-metastasis and no hepatitis flares were protective factors for PFS. Prophylactic lamivudine demonstrated similar efficacy as entecavir. Conclusions: Prophylactic agents are efficacious for prevention of HBV reactivation in HCC patients receiving TACE. Achievement of undetectable HBV DNA levels displayed a significant capability in improving PFS. Moreover, persistent tumor residual lesions, positive HBV DNA and hepatitis B flares might be causes of tumor progression in these patients.

The primary error sources of engineering design for bolted beam reaction system with large size are mainly from the deformation of structure, mechanical behavior of connection joints. In addition, the simplifi ed calculation method of bolted connection has not formed a unifi ed understanding. A vertical static load test was carried out in the laboratory, and the deformation laws of the reaction beam were analyzed to obtain the mechanical characteristics of the connection joints by controlling the defl ection of the reaction beam. The composite eff ect coeffi cient k l of the variable section panel structure was introduced to the theoretical solution of the defl ection of the variable cross-section beam. Simultaneously, the fi nite element method was employed to establish the detailed model of the beam reaction system. The mechanical behavior of the reaction beam and the bolted joint are extensively studied, and the simplifi ed method of bolted joint is improved. The bolted connection is simplifi ed as a semi-rigid joint, and then the theoretical formula is proposed to calculate the defl ection and deformation of the beam structure under bolted connection. The defl ection and deformation of the reaction beam by the test and theoretical formula are consistent. The results show that the theoretical formula can well calculate the defl ection and deformation of structure members under bolted connection.
