Background: Conspicuous differences in participation rates for breast self-examination (BSE), clinical breast examination (CBE), and referral for further investigations have been observed indicating involvement of a number of different factors. This study analysed determinants for participation in different levels of the breast cancer screening process in Indian females. Materials and Methods: An intervention group of 52,011 women was interviewed in a breast cancer screening trial in Trivandrum district, India. In order to assess demographic, socio-economic, reproductive, and cancer-related determinants of participation in BSE, CBE, and referral, uni- and multi-variate logistic regression was employed. Results: Of the interviewed women, 23.2% reported practicing BSE, 96.8% had attended CBE, and 49.1% of 2,880 screen-positives attended referral. Results showed an influence of various determinants on participation; women who were currently not married or who had no family history of cancer were significantly less likely to attend the screening process at any level. Conclusions: Increasing awareness about breast cancer, early detection methods, and the advantages of early diagnoses among women, and their families, as well as health care workers offering social support, could help to increase participation over the entire screening process in India.

Breast cancer is the most common cancer among women globally. This study was conducted to compare the awareness of breast cancer and the practice of breast self-examination (BSE), clinical breast examination (CBE) and mammography screening among rural females in Pahang and Perak. A cross-sectional study was carried out in five selected rural districts of Pahang and Perak. Two hundred and fifty households were randomly selected and interviewed face to face using a semi-structured questionnaire. The majority of residents from both states were Malay, aged between 50 and 60 years and had a secondary level of education. Malay women aged 40-49 years and women with a higher level of education were significantly more aware of breast cancer (p<0.05). About half of these women practiced BSE (60.7%) and CBE (56.1%), and 7% had underwent mammography screening. The results of this study suggest that women in Pahang and Perak have good awareness of breast cancer and that more than half practice BSE and CBE. The women's level of education appears to contribute to their level of knowledge and health behaviour. However, more effort is needed to encourage all women in rural areas to acquire further knowledge on breast cancer.

The distribution and activities of hydrolytic enzymes (cellulolyti, hemicellulolytic,pectinolytic and others) in the rumen compartments of Hereford bulls fed 100% alfalfa hay based diets were evaluated. The alfalfa proportion in the diet was gradually increased for two weeks. Whole rumen contents were processed into four fractions: Rumen contents including both the liquid and solid fractions were homogenized and centrifuged, and the supernatant was assayed for enzymes located in whole rumen contents (WRE); rumen contents were centrifuged and the supernatant was assayed for enzymes located in rumen fluids (RFE); feed particles in rumen contents were separated manually, washed with buffer, resuspended in an equal volume of buffer, homogenized and centrifuged and supernatant was assayed for enzymes associated with feed particles (FAE); and rumen microbial cell fraction was separated by centrifugation, suspended in an equal volume of buffer, sonicated and centrifuged, and the supernatant was assayed for enzymes bound with microbial cells (CBE). It was found that polysaccharide-degrading proteins such as $\beta$-1,4-D-endoglucanase, $\beta$-1,4-D-exoglucanase, xylanase and pectinase enzymes were located mainly with the cell bound (CBE) fraction. However, $\beta$-D-glucosidase, $\beta$-D-fucosidase, acetylesterase, and $\alpha$-L-arabinofuranosidase were located in the rumen fluids (RFE) fraction. Protease activity distributions were 37.7, 22.1 and 40.2%, and amylase activity distributions were 51.6, 18.2 and 30.2% for the RFE, FAE and CBE fractions, respectively. These results indicated that protease is located mainly in rumen fluid and with microbial cells, whereas amylase was located mainly in the rumen fluid.

팜 스테아린을 아세톤을 이용한 분별을 하여 POO와 POP가 많이 함유된 분별유지(PSL)를 얻었다. 분별을 위한 조건으로는 분별온도 $29.3^{\circ}C$, 아세톤과의 비율 1:5.7(w/v), 분별시간은 24시간이었다. 이후 천연 식물고체지들(sal fat, illipe fat, kokum fat, shea stearin fat, shea butter)과 PSL을 다양한 비율(50:50, 60:40, 65:35, 70:30)로 혼합하여 상용화되고 있는 CBE와 SFI를 비교하였으며, 총 지방산 조성 및 위치별 지방산 조성 분석과 TAG 분자들의 조성과 함량을 알아보았다. GC에 의한 지방산 조성 분석 결과, PSL의 경우 palmitic, oleic 그리고 linoleic acid 순으로 함량이 높았으며, 천연 식물고체지의 경우 대부분 stearic, oleic 그리고 palmitic acid의 순으로 높은 함량을 나타내었다. 또한, sal fat, illipe fat 및 kokum fat의 경우 sn-2 위치에 불포화지방산인 oleic acid가 90% 이상 존재하는 것을 알 수 있었다. TAG 분자들의 PN값은 46~54 사이에 존재하였다. PSL의 경우 PN 48에서 86.53 area%로 가장 높게 나타났으나, 천연 식물고체지들의 경우 대부분 PN 50과 52에서 주로 TAG 분자들이 존재하였다. 천연 식물고체지와 PSL을 다양한 비율로 혼합하였을 때, 대부분의 경우 PSL의 함량이 감소할수록 SFI는 증가하는 경향을 보였다. 특히, sal fat과 혼합하였을 때, CBE와 유사한 SFI를 나타내었다. Sal fat과 PSL의 blending 혼합물의 경우 oleic acid의 함량이 가장 많았고, PSL의 함량이 낮아질수록 palmitic acid의 함량은 감소하였고, stearic acid는 점차 높아지는 경향을 보였다.

Background: The burden of breast and cervical cancer is changing over time in developing countries. Regular screening is very important for early detection and treatment. In this study, we assessed inequalities in breast and cervical cancer screening rates in women according to household wealth status, and analyzed the potential predictors associated with a low cancer screening rate in Jordan. Materials and Methods: A nationwide populationbased cross-sectional survey collected information on different variables at the national level. All ever-married women (the phrase is used throughout the text to refer to women who had ever married) aged 15-49 years were included in the survey. Analysis of breast self-examination (BSE) and clinical breast examination (CBE) at least once in the previous year was carried out in 11,068 women, while lifetime Pap-smear testing was carried out in 8,333 women, aged 20-49 years. Results: Over 39% and 19% of ever-married Jordanian women reported having undergone a breast examination during the previous year and Pap smear examination at least once in their lifetime, respectively. The rate of BSE in the previous year was 31.5%, that of CBE in the previous year was 19.3%, and that of Pap smear examination at least once in life was 25.5%. The adjusted OR was higher for performing BSE (aOR 1.22, 95% CI 1.04-1.43), undergoing CBE (aOR 1.31, 95% CI 1.08-1.60) and undergoing Pap smear examination (aOR 2.38, 95% CI 1.92-2.93) among women in the highest wealth-index quintile as compared to those in the lowest quintile. The concentration index was 0.11 for BSE, 0.01 for CBE, and 0.27 for Pap smear examination. Women in their twenties, living in rural or the southern region of Jordan, with an elementary school education or less, who listened to the radio or read the newspaper not more than a few times a year, and nulliparous women were less likely to undergo breast and cervical cancer screening. Conclusions: The rates of breast and cervical cancer screening are low in Jordan. Reducing the sociodemographic and economic inequalities in breast and cervical cancer screenings requires concerted outreach activities for women living under socially deprived conditions.

InGaAs 박막의 facet 성장을 연구하기 위하여 triethygallium(TEGa), trimethylindium (TMIn)과 사전 열분해하지 않은 monoethylarsine (MEAs)을 사용하여 chemical beam epitaxy (CBE) 법으로 InGaAs 박막을 선택적으로 성장시켰다. 성장 온도와 패턴의 방향에 따라 facet 형성이 매우 다르게 나타났다. 마스크를 [11] 방향으로 제작한 기판에서는 facet의 면이 (311), (377)과 (11)의 여러 면이 형성되었으나 성장 온도가 올라감에 따라 (311)한 면으로 발전하였다. 또한 마스크를 [011]방향으로 하였을 때는, 성장 온도가 증가함에 따라 facet은 (11)h가 (111)면에서 (111)면으로 변하였다. 이러한 결과들은 측면에서 원료가스의 표면 이동 거리가 성장 온도에 따라서 변화하는 차이에 기인하는 것으로 믿어진다. U자 형태를 가지는 (100)의 윗면은 간단한 dangling bond 모형으로 설명할수 있었다.

Undoped GaAs has been successfully grown by chemical beam epitaxy (CBE) via surface decomposition process using arsine $(AsH_3)$ and trimethylgallium (TMG). Three distinct regions of temperature-dependent growth rates were identified in the range of temperatures from 570 to $690^{\circ}C$. The growth rates were found strongly dependent on the V/III ratio between 5 and 30. The growth rate at low V/III ratio seems to be determined by arsenic produced on the surface, whereas at high V/III ratio it shows dependence on the adsorption of TMG. Hall measurement and photoluminescence (PL) analysis show that the films are all p-type and that carbon impurities are primarily responsible for the background doping. Carbon concentrations have been found to be reduced by two orders of magnitude as compared to those of epilayers grown by CBE which employs TMG and arsenic obtained from precracked $AsH_3$ in a high temperature cell. It was also found that hydrogen atoms dissociated from unprecracked $AsH_3$ play an important role in removing hydrocarbon-containing species resulting in a significant reduction of car-bon impurities.
