Distributed Fusion Filter for Multi-rate Sampling Stochastic Singular Systems with Multiplicative Noises

Hao Jin,Jing Ma,Yun Li,Ming Zhao 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.2

The distributed fusion filtering problem is studied for multi-rate sampling stochastic singular linear systems with multiple sensors and stochastic multiplicative noises. The system is described at the highest sampling rate and different sensors may have different lower sampling rates. The white noise in measurement matrix is introduced to describe the stochastic disturbance. Firstly, based on decomposition in canonical form, the original singular system is transformed into fast and slow two subsystems. For the two reduced-order subsystems, the local filters (LFs) are given based on the “dummy” random variables. The cross-covariance matrices between any two local filtering errors are derived. Further, the distributed fusion filter weighted by matrices (FFWM) is obtained for the original singular system based on the well-known fusion algorithm in the linear minimum variance sense. Simulation example verifies the correctness and feasibility of the proposed algorithm.

Study on the Seismic Optimization Scheme of Steel Bundled-Tube Structure with Vertical Setback

Yong Hao,Feng Chen,Yun-hui Han,Xue-qian Hao,Chun-hui Du,Qiu-yu Ding 대한토목학회 2024 KSCE Journal of Civil Engineering Vol.28 No.2

In order to improve the seismic performance of vertical setback steel bundled-tube structure and meet the dynamic multi-objective requirements of seismic performance-based design, the optimization effects under rare earthquakes on the zone of fortification intensity 7 and 8 in China are researched by improving members stiffness and adding dampers in the weak parts of structure, based on dynamic elastic-plastic analysis. The results show that: 1) Under rare earthquakes on the zone of fortification intensity 7, increasing the stiffness of weak skirt beam can improve the seismic performance of spiral and symmetrical setback structure; 2) For the spiral setback structure, under rare earthquakes on the zone of fortification intensity 7, the damper can only be arranged at the junction of the first layer of the setback frame unit and the frame unit without setback. However, under rare earthquakes on the zone of fortification intensity 8, it is not advisable to install dampers at the weak areas; 3) After incorporating dampers at the weak areas of symmetrical setback structure, the optimized members experienced a reduction in stress levels, significantly decreased the inter-layer displacement angles with a maximum reduction of 43%, and the optimization effect is significant.

Zhao, Hao,Yin, Jie-Yun,Yang, Wan-Shui,Qin, Qin,Li, Ting-Ting,Shi, Yun,Deng, Qin,Wei, Sheng,Liu, Li,Wang, Xin,Nie, Shao-Fa Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.12

To assess the risk of cancers associated with sleep duration using meta-analysis of published cohort studies, we performed a comprehensive search using PubMed, Embase and Web of Science through October 2013. We combined hazard ratios (HRs) from individual studies using meta-analysis approaches. A random effect dose-response analysis was used to evaluate the relationship between sleep duration and cancer risk. Subgroup analyses and sensitivity analyses were also performed. Publication bias was evaluated using Funnel plots and Begg's test. A total of 13 cohorts from 12 studies were included in this meta-analysis, which included 723, 337 participants with 15, 156 reported cancer outcomes during a follow-up period ranging from 7.5 to 22 years. The pooled adjusted HRs were 1.06 (95% CI: 0.92, 1.23; P for heterogeneity =0.003) for short sleep duration, 0.91 (95% CI: 0.78, 1.07; P for heterogeneity <0.0001) for long sleep duration. In subgroup analyses stratified by cancer type, long duration of sleep showed an inverse relation with hormone-related cancer (HR=0.79; 95% CI: 0.65, 0.97; P for heterogeneity =0.009) and a greater risk of colorectal cancer (HR=1.29; 95% CI: 1.09, 1.52; P for heterogeneity =0.346). Further meta-analysis on dose-response relationships showed that the relative risks of cancer were 1.00 (95% CI: 0.99, 1.01; P for linear trend=0.9151) for one hour of sleep increment per day, and 1.00 (95% CI: 0.98, 1.01; P for linear trend=0.7749) for one hour of sleep increment per night. No significant dose-response relationship between sleep duration and cancer was found on non-linearity testing (P=0.5053). Our meta-analysis suggests a positive association between long sleep duration and colorectal cancer, and an inverse association with incidence of hormone related cancers like those in the breast. Studies with larger sample size, longer follow-up times, more cancer types and detailed measure of sleep duration are warranted to confirm these results.

Influence of Clinically Significant Portal Hypertension on Hepatectomy for Hepatocellular Carcinoma: a Meta-analysis

Tang, Yun-Hao,Zhu, Wen-Jiang,Wen, Tian-Fu Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.4

Background: Clinically significant portal hypertension (PHT) is considered as a contraindication for hepatectomy according to the guidelines of the European Association for Study of Liver and the American Association for Study of Liver Diseases. However, this issue remains controversial. Here we performed a metaanalysis to evaluate the impact of PHT on the results of hepatectomy for hepatocellular carcinoma (HCC). Methods: Cohort studies evaluating the impact of clinically significant PHT, defined as oesophageal varices and/or splenomegaly associated with thrombocytopenia, on the results of hepatectomy for HCC were identified using a predefined search strategy. Summary risk ratios (RRs) and 95% confidence intervals (95% CIs) for PHT and outcomes after hepatectomy for HCC were calculated. Results: Seven cohort studies which including 574 cases with PHT and 1,354 cases without PHT were considered eligible for inclusion. The meta-analysis showed that, in all patients, pooled RRs of post-operative liver failure, post-operative ascites, peri-operative blood transfusion, operative mortality, 3- and 5-year overall survival associated with PHT were 2.23 (95% CI: 1.48-3.34, P=0.0001), 1.77 (95% CI: 1.19-2.64, P=0.005), 1.23 (95% CI: 1.03-1.49, P=0.03), 2.58 (95% CI: 1.12-5.96, P=0.03), 0.82 (95% CI: 0.75-0.88, P<0.00001) and 0.76 (95% CI: 0.69-0.85, P<0.00001), respectively. In subgroup analysis, similar results were found in Child-Pugh class A patients. Conclusion: This meta-analysis suggests that presence of oesophageal varices and/or splenomegaly associated with thrombocytopenia is associated with higher rates of post-operative complications and poor long-term survival after hepatectomy for HCC.

현실적 직무소개(Realistic Job Previews)와 이직의도의 관계에 대한 연구

두운호(Du Yun Hao),신수영(Shin Soo Young) 한국인적자원관리학회 2016 인적자원관리연구 Vol.23 No.4

최근의 지식기반 경영환경에서는 인적자원의 효율적 활용과 더불어 인재를 유지할 수 있는 방안이 인적자원관리의 중요한 이슈로 떠오르고 있다. 즉, 구성원의 이탈로 인해 생기는 막대한 손실은 기업에게 치명적인 악영향을 미칠 수 있고, 이에 따라 조직에서는 입직단계의 사람들에게 과장되고 이상적인 기대를 갖게 하기 보다는 진실한 정보를 균형있게 제공하는 현실적 직무소개의 필요성이 제기되었다. 현실적 직무소개란 입사자들이 조직에 진입하여 적응하는 과정에서 조직과 직무에 관련된 정보를 정확하게 제공받음으로써 조직과 직무에 대한 비현실적 기대감을 현실적으로 변화시킬 수 있다는 개념이다. 본 논문에서는 개인-직무적합성(P-J fit) 관점과 조기업무적응(early work adjustment) 가설을 기반으로 현실적 직무소개가 어떻게 이직의도에 영향을 미치는가를 탐색하고자 한다. 그동안 선행연구에서는 현실적 직무소개와 조직유효성 사이의 관계에 집중할 뿐 현실적 직무소개가 이직의도에 영향을 미치는 과정을 탐색한 실증연구는 부족하였다. 따라서 본 논문에서는 현실적 직무소개의 긍정적 효과를 설명할 수 있는 효과적 대응전략(coping strategy)에 초점을 맞춰 이직의도에 영향을 미치는 과정을 밝히고자 한다. 이를 위해 재직기간 3년 미만의 종업원을 대상으로 총 177부의 설문지를 사용하여 가설을 검증하였다. 분석결과, 현실적 직무소개는 역할명료성에 정(+)의 관계가 있는 것으로 나타났고, 역할명료성은 이직의도와 부(-)의 관계가 있는 것으로 나타났다. 또한, 현실적 직무소개가 이직의도에 미치는 영향에 있어 역할명료성의 매개효과를 분석한 결과, 역할명료성의 부분매개효과가 지지되었다. 즉, 현실적 직무소개는 그 자체로도 이직의도를 줄일 수 있지만 역할명료화 등의 적극적인 대응전략을 통해 더 큰 효과를 발휘할 수 있는 것으로 밝혀졌다. The purpose of this study is to examine the effect of Realistic Job Previews(RJPs) to reduce employees’ turnover intention. By exploring the relationship among RJPs, role clarification and turnover intention, we attempted to explain the coping strategy during the organizational socialization process. With the data from 177 employees who worked less than 3 years in local Korean companies, we tested three hypotheses. According to the test results, RJPs has a positive relationship with role clarification. This suggests that organizations providing accurate, sufficient and symmetrical information will positively affect employees’ behavior during the introductory period. In addition, role clarification negatively affects turnover intention. This shows that if individuals have clearer responsibilities and duties, they will be less inclined to leave the job. Lastly, role clarification has a partial mediating effect on the relationship between Realistic Job Previews and turnover intention. This shows that even though Realistic Job Previews has a negative effect on turnover intention, employees are also influenced by other organizational mechanisms such as the role clarification.

Background: In mainland China, awareness of disease of elderly cancer patients largely relies on the patients' families. We developed a staged procedure to improve their awareness of disease. Materials and Methods: Participants were 224 elderly cancer patients from 9 leading hospitals across Southern China. A questionnaire was given to the oncologists in charge of each patient to evaluate the interaction between family and patients, patient awareness of their disease and participation in medical decision-making. After first cycles of treatment, increased information of disease was given to patients with cooperation of the family. Then patient awareness of their disease and participation in medical decision-making was documented. Results: Among the 224 cancer elderly patients, 26 (11.6%) made decisions by themselves and 125 (55.8%) delegated their rights of decision-making to their family. Subordinate family members tended to play a passive role in decision-making significantly. Patients participating more in medical decision-making tended to know more about their disease. However, in contrast to the awareness of disease, patient awareness of violation of medical recommendations was reversely associated with their participation in medical decision-making. Improvement in awareness of diagnosis, stages and prognosis was achieved in about 20% elderly cancer patients. About 5% participated more actively in medical decision-making. Conclusions: Chinese elderly cancer patient awareness of disease and participation in medical decision-making is limited and relies on their family status. The staged procedure we developed to improve patient awareness of disease proved effective.
