Seroprevalence of Toxoplasma gondii Among Primary School Children in Shandong Province, China
Ke-Sheng Xin,Hui Liu,Hong-Bing Wang,Zong-Liang Yao 대한기생충학열대의학회 2015 The Korean Journal of Parasitology Vol.53 No.4
Although Toxoplasma gondii infection in primary school children has been investigated in many countries, limited surveys have been available in primary school children in China. In the present study, we report the seroprevalence of T. gondii infection in primary school children in Shandong province, China. Sera from 6,000 primary school children were evaluated for T. gondii antibodies with ELISA. The overall seroprevalence of T. gondii infection was 16.0% (961/6,000), of which 14.5% (870/6,000) were positive for anti-T. gondii IgG antibodies, 3.4% (206/6,000) positive for IgM, and 1.9% (115/6,000) were positive for both IgG and IgM. The results of the present investigation indicated a high seroprevalence of T. gondii infection in primary school children in Shandong province, China. Therefore, effective measures should be taken to prevent and control T. gondii infection in primary school children in this province. To the best of our knowledge, this is the first report of T. gondii seroprevalence in primary school children in Shandong province, China.

Xin, Ke-Peng,Du, Mao-Lin,Li, Zhi-Jun,Li, Yun,Li, Wuyuntana,Su, Xiong,Sun, Juan Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.6
The aim of this study was to determine the mortality rate and burden of urinary tract cancers among residents of Inner Mongolia. We analyzed mortality data reported by the Death Registry System from 2008 to 2012. The rate of mortality due to urinary tract cancer was 2.04 per 100,000 person-years for the total population, 2.91 for men, and 1.11 for women. Therefore, the mortality rate for men was 2.62-fold the mortality rate for women, constituting a statistically significant difference (p<0.001). Over the period 2008 through 2012, the total potential years of life lost was 1388.1 person-years for men and 777.1 person-years for women, and the average years of life lost were 7.71 years per male decedent and 12.0 years per female decedent. Mortality due to urinary tract cancers is substantially greater among the elderly population. Further, the mortality rate associated with urinary tract cancers is greater for elderly men than it is for elderly women. Therefore, in Inner Mongolia, urinary tract cancers appear to pose a greater mortality risk for men than they do for women.
Narrowband Signal Localization Based on Enhanced LAD Method
Ke Xin Jia,Zi Shu He 한국통신학회 2011 Journal of communications and networks Vol.13 No.1
In this paper, an enhanced localization algorithm based on double thresholds (LAD) is proposed for localizing narrowband signals in the frequency domain. A simplified LAD method is first studied to reduce the computational complexity of the original LAD method without performance loss. The upper and lower thresholds of the simplified LAD method are directly calculated by running the forward consecutive mean excision algorithm only once. By combining the simplified LAD method and binary morphological operators, the enhanced LAD method is then proposed and its performance is simply discussed. The simulation results verify the correctness of discussion and show that the enhanced LAD method is superior to the LAD with adjacent cluster combining method, especially at low signal-to-noise ratio.
Study on wall pressure and hysteresis behaviors of a novel dual-bell nozzle
Ke Xin Wu,Gerald Canaan Sohn,Ruoyu Deng,Hao Jia,Heuy Dong Kim,Xianghui Su 대한기계학회 2023 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.37 No.9
The dual-bell nozzle is a kind of altitude adaptive nozzle for improving the performance of space launchers as well as future reusable launch vehicles. Numerical investigations have been conducted on a planar dual-bell nozzle to illustrate the flow characteristics at sea level, “sneak” transition, and altitude modes, respectively. Findings from computational fluid dynamics have been contrasted with experimental data from the open literature. The normalized pressure distributions along the dual-bell nozzle wall for different turbulence models are compared to the pressure measurements taken during the experiment by fixing the nozzle pressure ratio (NPR) at 29.8. The NPR value gradually rises across a large range from 6 to 55 to explore the evolution of the flow characteristics. The pressure distributions along the nozzle wall and shock position have been investigated. The hysteretic behaviors occur in dual-bell nozzles close to the contour inflection. The wall pressure and hysteresis behaviors have been expounded in detail.
영화 오프닝 타이틀 심상적 정체성의 유지 및 가변성 연구 - 〈미션 임파서블〉 시리즈 오프닝 타이틀을 중심으로
우게인(Ke-Xin Hu),유우종(Woo-Jong Yoo) 한국콘텐츠학회 2023 한국콘텐츠학회논문지 Vol.23 No.12
With the rapid development of cultural content and market demand, many films struggle to maintain a clear identity over an extended timeline or face frustration in their expansion into series due to monotonous and dull visual imagery. Consequently, the central issue that arises is how to maintain the identity of a film series while introducing variability tailored to the characteristics of each installment. This paper divides the analysis into two parts: an internal perspective that encompasses the themes of the films through semiotic theory and an external perspective that conveys the visual imagery of the films. Through a case study analysis of the opening titles in the <Mission: Impossible> film series (Series 1-6), this paper reveals how the expressive features within the opening titles contribute to maintaining the imagery identity of the films. The results of the analysis suggest that opening titles in a film series play a crucial role in maintaining imagery identity as a product of visual design. Firstly, the symbols represented in the opening titles greatly assist in preserving internal thematic consistency within the film series. Secondly, the representation of visual elements in each opening title within the series should follow consistency principles while also pursuing engaging variations to maintain imagery identity. Lastly, the key to successfully preserving a films imagery identity lies in effectively adapting to the influence of societal changes on the films.
Proteomic Profiling of Serum from Stage I Lung Squamous Cell Carcinoma Patients
Li, Xin-Ju,Wu, Qi-Fei,He, Da-Lin,Fu, Jun-Ke,Jin, Xin Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.4
Objectives: This study employed proteomic profiling to identify specific tumor markers that might improve early diagnosis of lung squamous cell carcinoma. Methods: Serum samples were isolated from 30 patients with stage I lung squamous cell carcinoma and 30 age-and gender-matched healthy controls, and proteomic profiles were obtained by matrix-assisted laser desorption ionization time of flight mass spectrometry. Results: Three highly expressed potential tumor markers were identified in the sera of stage I lung squamous cell carcinoma patients, with molecular weights of 3261.69, 3192.07, and 2556.92 Da. One protein peak with molecular weight 3261.69 Da was chosen as the candidate biomarker and identified as a fibrinogen alpha chain through a search of the IPI, NCBI or SWISS-PROT protein databases. Conclusion: As a potential tumor biomarker, fibrinogen alpha chain may be applicable for the early diagnosis and prognosis of lung squamous cell carcinoma patients.

Since China pays more attention to cultural heritage, it becoming increasingly important for us to preserve traditional costumes and pass them down. The purpose of this study is to remake the costumes in museums as 3D virtual ones and to display them, thus contributing to the preservation. We studied the traditional costumes of the Qing Dynasty and reviewed the current situation of museums online. Selected 5 kinds of Paofu of the Empress in the Qing Dynasty as the object of study and developed an effective plan to make the virtual Paofu. Finally, based on the 3D virtual costumes and costume information, we built a website of the digital museum for the costumes. We have found that the results of the study have basically lived up to our expectations after tests and evaluations.
