  • Background: Cervical cancer is common among women worldwide. A multitude of risk factors aggravate the disease. This study was conducted to: (1) determine the prevalence and (2) make a comparative analysis of the socio-demographic and behavioural risk factors of cervical cancer and knowledge, attitude and practice between rural and urban women of North Bengal, India. Study Design: Community-based cross-sectional study. Methods: A survey (first in North Bengal) was conducted among 133 women in a rural area (Kawakhali) and 88 women in an urban slum (Shaktigarh) using predesigned semi-structured questionnaires. The respondents were informed of the causes (including HPV), signs and symptoms, prevention of cervical cancer and treatment, and the procedure of the PAP test and HPV vaccination. Results: The prevalence of risk factors like multiparity, early age of marriage, use of cloth during menstruation, use of condom and OCP, early age of first intercourse was 37.2%, 82%, 83.3%, 5.4%, 15.8% and 65.6% respectively. Awareness about the cause, signs and symptoms, prevention of cervical cancer, PAP test and HPV vaccination was 3.6%, 6.3%, 3.6%, 9.5% and 14.5% respectively. Chi-square testing revealed that in the study population, significant differential at 5% exists between rural and urban residents with respect to number of children, use of cloth/sanitary napkins, family history of cancer and awareness regarding causes of cervical cancer. Regarding KAP, again using chi-square tests, surprisingly, level of education is found to be significant for each element of KAP in urban areas in contrast to complete absence of association between education and elements of KAP in rural areas. Conclusions: A large number of risk factors were present in both areas, the prevalence being higher in the rural areas. The level of awareness and role of education appears to be insignificant determinants in rural compared to urban areas. This pilot study needs to be followed up by large scale programmes to re-orient awareness campaigns, especially in rural areas.

  • 대, 소조기에 마산만에서 연속관측한 자료를 사용하여 만구 단면의 유속 변동특성을 구명하기 위하여 net velocity와 RMS속도의 등양선 및 순 유출입량을 계산하여 검토하였다. 최강유속은 수도 중앙과 서부의 4m 이하의 표층에서 나타나고, 최대 유입속도 24cm/sec 최대 유출속도는 15 cm/sec이다. 최강유속 시간임에도 불구하고 4m 이심에서는 유속이 약하여 $0{\sim}2cm/sec$에 불과하다. 만구 단면의 가장자리의 상층에 역류가 존재한다. net velocity는 비가 오지 않은 대조기의 경우 유출유속은 만구단면 서부에서 나타나며, 유입유속은 단면 동부에서 나타난다. 비온 직후의 소조기에는 이와 정반대로 흐른다. RMS속도의 최대 세기는 대조기에 $11.3{\sim}15.0cm/sec$, 소조기에 $7{\sim}10.3cm/sec$로서 단면 서부의 표층에 있으며, 매 조석주기마다 거의 동일위치에서 계속 존재한다. 순 통과유량은 건기에 $-39.7m^3/sec$, 우기 $-170m^3/sec$로서 유출이 탁월하다. 항유성분은 건기에는 조석잔차류가 우세하지만, 소조기의 강우시에는 밀도류가 우세한 것으로 추리된다.

  • High-speed railway system is exposed to severe aerodynamic problems and has various requirements both on design and operation; 80% of running resistance is composed of aerodynamic drag, the cross-sectional area and portal shape of tunnel should be designed under aerodynamic consideration, and natural wind velocity should always be monitored to prevent the overturning of train by crosswinds. In addition, most of the aerodynamic problems are proportional to the running speed or square of the running speed. Thus, when the running speed of a high-speed railway system either on operation or under construction is to be increased, the aerodynamic problems should be assessed in advance and the countermeasures should be prepared to alleviate the aerodynamic problems to meet certain requirements. In this study, aerodynamic problems that could occur at speed up of high-speed line have been investigated and aerodynamic requirements to meet the increased operational speed have been studied referring the international and domestic rules, guidance, and recommendations.

  • Purpose: The purpose of this study was to investigate differences in vaccination status and awareness between influenza and pneumococcal vaccinations in the elderly. Methods: This cross-sectional study was used with a questionnaire. Data were collected from 107 older people over 65 years registered at one community center in December, 2012. The data were analysed with Chi-square, Fisher's exact-test, Wilcoxon Signed rank sum test, Mann-Whitney U test, and Kruskall-Wallis test. Results: There were significant differences in the experiences of vaccination and reason for unvaccination by vaccine types. The mean scores for awareness of vaccination were 1.81 (range 0~3) in influenza and 1.50 in pneumococcus (range 0~3). There was a significant difference in awareness by vaccine types (Z=6.12, p<.001). There was a positive association between influenza and pneumococcal vaccination awareness (rho=.236, p=.014). Conclusion: This study showed different vaccination status and awareness in vaccine types. It is necessary to consider vaccination status and awareness by vaccine types of the target population in the education program related to vaccination.

  • The research objective was to find out how Total Quality Management (TQM) mediates antecedents of employee performance variables? The research was conducted with a quantitative approach while the research design was cross sectional. The research model was tested using the structural equation modeling approach with partial least square analysis tools to test the influence among research variables. The research sample consisted of 315 respondents who answered a questionnaire in August-September 2019 at manufacturing companies in East Java. The results showed that situational leadership did not affect employee performance, but did affect the successful implementation of TQM. The performance measurement system has no direct effect on employee performance. The performance measurement system has a direct effect on employee performance. Organizational culture has a direct effect on both employee performance and the application of TQM, so that the application of TQM can improve employee performance. TQM implementation variable acts as a mediation between situational leadership and organizational culture on employee performance. The relationship that was originally a direct influence turned into an indirect effect through TQM. The TQM variable is not proven to be an intervening variable between the performance measurement system and employee performance. There is a direct relationship between these two variables.

  • Purpose: The aim of this study was to estimate the prevalence of urinary incontinence among nursing home residents and to identify the factors associated with this condition. Method: The data were collected from 618 subjects (146 males and 472 females; mean age $79.9{\pm}8.4$ yr; range 65-102 yr) of 30 nursing homes in Seoul, Gyeonggi-do and Gangwon-do in this cross-sectional study. The data were analyzed by chi-square test, t-test, and multiple logistic regression by using the SPSS/PC ver 12.0 program. Results: The prevalence of UI was 64.7% (64.6% in women; 65.1% in men). After adjustment for each of the variables considered in this study, six potential factors were strongly associated with UI: activities of daily living, comorbidity, age, cognition, specialty of the facility, and a bladder training program. Conclusion: Our finding suggests that it is necessary to develop a program for promotion of activities of daily living and to provide a bladder training program to prevent urinary incontinence among nursing home residents.

  • The objective of this paper is to explore how board gender diversity affects corporate sustainability performance. Therefore, this paper examines the direct association between board gender diversity with corporate sustainability performance and the mediation effect of enterprise risk management (ERM) on this association. The study employed a cross-sectional survey method. Data were collected from annual reports, websites, and through the questionnaires that were distributed to Chief Financial Officers (CFOs) of all the listed companies of Dhaka Stock Exchange, Bangladesh. The partial least square technique of Structural Equation Modelling (SEM) approach was employed for data analysis. The result did not find support for the direct association between board gender diversity and sustainability performance in Bangladesh context. This implies that contextual factors, such as, male-dominant board, appointment of female directors based on family ties, lack of education and expertise etc. may discount gender diversity direct influence on sustainability performance. However, the study finds strong support for the mediating role of ERM use within the corporate structure. Further analysis of indirect effect suggests that ERM use mediates the relationship of board gender diversity and sustainability performance in full. This implies that in the Bangladesh context effective use of ERM is highly recommended.

  • Background: Breast and cervical cancers are the most common types of cancer in women worldwide. Previous studies in Asia have shown that related knowledge and awareness is low among female university students. The goal of this study was to assess breast and cervical cancer knowledge, practices, and awareness among female university students in Samsun,Turkey. Materials and Methods: This research was a cross-sectional survey of female university students using a self-administered. questionnaire to investigate participant awareness and knowledge of breast and cervical cancer. A total of 301 female university students participated. Descriptive statistics and chi square tests were used for data analysis. Results: The mean age of the participants in this study was $22.0{\pm}5.91$ years. Regarding family history, 89.7 % of the students had no known familial history of breast cancer. Students (65.4%) had knowledge about breast self examination and 52.2 % of them had performed breast self examinationm while 55.1% of them had knowledge about prevention of cervical cancer. Conclusions: Although the results are preliminary, the study points to an insufficient knowledge of university students in Samsun about breast and cervical cancer.

  • The output power of turbine is greatly affected by the losses generated within the passage. In order to develop a better turbine or loss models, an experimental study was conducted using a linear cascade experimental apparatus. The total pressure loss and flow structures were measured at two cross-sectional planes located downstream of blade row. Measurement was conducted in a steady state for the several different locations of the blade row along the rotational direction. The blade row moved by 20 % of the pitch, and tip clearance was varied from 2% to 8%. Axial-type blades were used and its blade chord was 200mm. A square nozzle was applied and its size was $200mm{\times}200mm$. The experiment was conducted at a Reynolds number of $3{\times}10^5$ based on the chord. Nozzle flow angle sets to $65^{\circ}$ based on the axial direction and the solidity of blade row was 1.38. From the experimental results, the total pressure loss was greatly varied in the receding region than in the entering region. The flow properties within the blade passage were strongly changed according to the location of blade row.
