BACKGROUND Panic disorders frequently occur with affective disorders,particularly bipolar *** with panic disorder and bipolar disorder are more likely to present with severe symptoms,such as high rates of suicidal behavior,poor symptomatic and functional recovery,and poor drug *** To investigate the psychological characteristics of panic disorder patients related to *** A total of 254 patients(136 men and 118 women,mean age=33.48±3.2 years)who were diagnosed with panic disorder were included in the *** disorder with bipolarity(BP+)was defined as a score of≥7 on the Korean version of the Mood Disorder Questionnaire(K-MDQ),and a score lower than 7 was considered as a panic disorder without bipolarity(BP-).Self-report questionnaires were analyzed to examine their association with *** tests used in the study were the Mood Disorder Questionnaire(MDQ),Panic Disorder Severity Scale,Beck Depression Inventory,State-Trait Anxiety Inventory(STAI),Temperament and Character Inventory(TCI),and Minnesota Multiphasic Personality Inventory(MMPI).Statistical analyses were performed to evaluate the correlation between bipolarity of panic disorder patients and various psychological test results indicative of psychological *** Patients with a K-MDQ score of 7 or more were considered to have a history of manic or hypomanic episodes(BP+group,n=128),while patients with K-MDQ scores below 7 were defined as those without bipolarity(BP-group,n=126).The BP+group were more likely to be unmarried(single 56.2%vs 44.4%,P=0.008)and younger(30.78±0.59 vs 37.11±3.21,P<0.001).Additionally,the BP+group had significantly higher scores on psychological assessment scales,such as the hypochondriasis,psychopathic deviate,masculinity-femininity,psychasthenia,schizophrenia,and hypomania(Ma)in MMPI,and novelty seeking,harm avoidance and self-transcendence in TCI,and STAI(state and trait)compared to the *** logistic

Structural optimization for ball valve made of CF8M stainless steel

引用

中国有色金属学会会刊：英文版 2009年第B9期19卷 258-261页

作者： Seung-Gyu KIM Seok-heum BAEK Young-Chul park Department of Mechanical Engineering Dong-A University

The mechanical and chemical properties of CF8M were studied through experiments. An application of CF8M in valve body was analyzed by using finite element method(FEM) to evaluate the structural safety. An optimization containing several variables based on the response surface method(RSM) was conducted to find the optimum dimension of the valve. The results show that using this process can save valve mass as well as the computational expense effectively.

Solvent rinse treatments using polar methanol(Me OH)and nonpolar n-hexane have been developed for controlling material concentration gradients along the longitudinal direction of non-fullerene acceptor-based bulk heterojunction(BHJ)films comprised of electron donor polymer,PBDB-T and acceptor,*** the used solvents(chlorobenzene with 1 vol%DIO)were completely evaporated,ITIC-m rich domains were formed at the top surface of the BHJ films after they were rinsed with Me OH,as evidenced by water contact angle,atomic force microscopy,time-of-flight secondary ion mass spectroscopy,which led to enhanced electron transport in the conventional structure of organic solar cells(OSCs).In contrast,after rinsing with n-hexane,ITIC-m rich domains were formed at the bottom surface of the films,which improved electron transport in the inverted structure *** enhanced carrier transports increased the PCEs(11.80%and 11.15%)in both conventional and inverted OSCs by 10.29%and 10.35%compared with control *** versatile control of material concentration gradients is determined to be feasible owing to the chemical interaction of the used substrates(glass,PEDOT:PSS,and Zn O)and rinsing solvents.

Metabolic syndrome, lifestyle risk factors, and distal colon adenoma: A retrospective cohort study

引用

World Journal of Gastroenterology 2011年第35期17卷 4031-4037页

作者： Moon-Chan Kim Chang-Sup Kim Tae-heum Chung Hyoung-Ouk park Cheol-In Yoo Department of Family Medicine Ulsan University Hospital University of Ulsan College of Medicine Ulsan 682-714 South Korea Department of Occupational and Environmental Medicine Ulsan University Hospital

AIM: To investigate relationships between colorectal adenoma incidence, metabolic syndrome (MS) components and lifestyle factors. METHODS: We conducted a retrospective cohort study using data from individuals who had multiple sigmoidoscopies for colon cancer at the Health Promotion Center of Ulsan University Hospital in Korea from 1998 to 2007. RESULTS: By multivariate analysis, the incidence of distal colon adenoma was increased by more than 1.76 times in individuals with at least one component of MS compared to those without a component of MS. After adjustment for age, gender, smoking, drinking, and physical exercise, only high body mass index (BMI) was significantly associated with the incidence of distal colon adenoma (Hazard ratio 1.66, 95% confidence interval 1.05-2.62). CONCLUSION: Our results suggest that high BMI may increase the risk of colorectal adenoma in Korean adults.
