End Milling of Stainless Steel Using Vegetable Oil Cutting Fluid
Denni Kurniawan(대니쿠니아완),Safian Sharif,Muhammad Azrul Hisyam,Lim Joong Yeon(임중연) 대한기계학회 2009 대한기계학회 춘추학술대회 Vol.2009 No.11
Vegetable oil can be alternative cutting fluid with its positive impact to both machine shop workers’ health and environmental friendliness. Its use as cutting fluid is investigated by performing end milling of hardened stainless steel using coated carbide tool with minimum quantity lubrication technique. Comparisons were made by other cooling techniques, i.e. dry, flood cooling using emulsion, and minimum quantity lubrication using fatty alcohol in terms of tool life and surface roughness. Results showed that minimum quantity lubrication using vegetable oil outperformed other cooling techniques, thus provided positive evaluation on its particular experimental use.

Background: Breast cancer is one of the most common cancers among females worldwide. The aim of this study was to assess the knowledge and practice about breast cancer and its related factors among women in Baghdad city, Iraq. Materials and Methods: A cross-sectional study was conducted among 508 women aged 18 to 55 years from four non-governmental organizations (NGO) in Baghdad city, Iraq. A self-administered questionnaire on breast cancer knowledge and practice was distributed to participants during weekly activity of the NGO. Results: A total of 61.2% of the respondents had poor knowledge, only 30.3% performed breast self-examination (BSE) and 41.8% said that they did not know the technique to perform BSE. Associations between knowledge and marital status and age were significant. For practice, working status, education, age and family income were significant. After controlling for cofounders, the most important contributing factors for poor knowledge among respondents were marital status and not performing BSE, with adjusted odds ratio of 1.6 and 1.8 respectively. Conclusions: Breast cancer knowledge and practice of BSE are poor among women in Baghdad city, Iraq. More promotion regarding breast cancer signs and symptoms and also how to perform BSE should be conducted using media such as television and internet as these constituted the main sources of information for most women in our study.

Spatial Analysis of Colorectal Cancer Cases in Kuala Lumpur
Shah, Shamsul Azhar,Neoh, Hui-Min,Syed Abdul Rahim, Syed Sharizman,Azhar, Zahir Izuan,Hassan, Mohd Rohaizat,Safian, Nazarudin,Jamal, Rahman Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.3
Background: In Malaysia, data from the Malaysian Health Ministry showed colorectal cancer (CRC) to be the second most common type of cancer in 2007-2009, after breast cancer. The same was apparent after looking at males and females cases separately. In the present study, the Geographic Information System (GIS) was employed to describe the distribution of CRC cases in Kuala Lumpur (KL), Malaysia, according to socio-demographic factors (age, gender, ethnicity and district). Materials and Methods: This retrospective review concerned data for patients diagnosed with colorectal cancer in the years 1995 to 2011 collected from the Wilayah Persekutuan Health Office, taken from the cancer notification form (NCR-2), and patient medical records from the Surgical Department, Universiti Kebangsaan Malaysia Medical Centre (UKMMC). A total of 146 cases were analyzed. All the data collected were analysed using ArcGIS version 10.0 and SPSS version 19.0. Results: Patients aged 60 to 69 years accounted for the highest proportion of cases (34.2%) and males slightly predominated 76 (52.1%), Chinese had the highest number of registered cases at 108 (74.0%) and staging revealed most cases in the 3rd and 4th stages. Kernel density analysis showed more cases are concentrated up in the northern area of Petaling and Kuala Lumpur subdistricts. Spatial global pattern analysis by average nearest neighbour resulted in nearest neighbour ratio of 0.75, with Z-score of -5.59, p value of <0.01 and the z-score of -5.59. Spatial autocorrelation (Moran's I) showed clustering significant with p<0.01, Z score 3.14 and Moran's Index of 0.007. When mapping clusters with hotspot analysis (Getis-Ord Gi), hot and cold spots were identified. Hot spot areas fell on the northeast side of KL. Conclusions: This study demonstrated significant spatial patterns of cancer incidence in KL. Knowledge about these spatial patterns can provide useful information to policymakers in the planning of screening of CRC in the targeted population and improvement of healthcare facilities to provide better treatment for CRC patients.
