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.

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.

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.
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.
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.

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
문화 콘텐츠의 발전과 시장 수요의 급속한 발전에 따라 긴 타임라인에서 수많은 영화가 명확한 성격을 유지하지 못하거나, 단조롭고 지루한 영화 이미지로 인해 시리즈로 확장되는 과정에서 좌절을 겪고 있다. 따라서 어떠한 방식으로 시리즈 영화의 정체성을 유지하며 각 작품의 특징에 맞게 가변성을 추가하는지가 가장 핵심적인 문제로 떠오르게 되었다. 본 논문은 기호학 이론을 통한 영화의 주제를 포괄하는 내부 관점과 영화의 청각적 이미지를 전달하는 외부 관점의 두 부분으로 나누고, 시리즈 영화 〈미션 임파서블〉 1 ~ 6편의 작품에 대한 사례 분석을 통해 오프닝 타이틀 속의 표현 특징을 파악하여 심상적으로 영화 정체성을 유지하는 방법을 밝혀냈다. 분석한 결과는 시리즈 영화 오프닝 타이틀은 시청각적 디자인의 결과물로써 심상적 정체성의 유지하기에 매우 중요한 역할을 하고 있는 것으로 판단했다. 첫째, 오프닝 타이틀에 표현된 기호는 시리즈 영화의 내부적 주제의 일관성 유지에 가장 큰 도움을 주었다. 둘째, 시리즈 내의 각 오프닝 타이틀 속 시청각 요소의 표현 방식은 심상적 정체성 유지를 위해 일관성 원칙을 따르면서도 재미있는 변화를 추구해야한다. 셋째, 영화의 심상적 정체성을 성공적으로 유지하는 열쇠는 시대 변화가 영화에 미치는 영향을 잘 따르는 것이다. 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.
