This study was carried out to investigate the effects of dietary lipid sources and meal frequency on growing performance and lipid metabolism in Sprague-Dawley strain male rats. The experiment was conducted in 4$\times$2 factorial arrangement with 4 sources of dietary lipid(palm oil, beef tallow, soybean oil and hydrogenated soyben oil) and 2 meal frequencies(ad-libitum or meal feeding). During the 4-week feeding period the rats were fed either ad-libitum (AL) or a single daily 3-hour meal (09 : 02-12 : 00) during the dark period. In vitro cultures were carried out to study the cholesterol synthetic activity in hte liver prepared from rats used in feeding trials. And in vitro cultures were also carried out to study the lipogenic and lipolytic activity in the liver and adipose tissues prepared from rats used in feeding trials. Present data indicated that body weight gain, feed intake and FER of AS(ad-libitum+soybean oil)and AHS(ad-libitum+hydrogenated soybean oil) group were significantly(p<0.05) higher than those of the other groups. It was found that the feed intake of MF group was much less than that of AL group. Total body weight gained by MF group was only 60% of AL group. Growing performance was not affected by dietary lipid sources. The cholesterol synthetic activity in liver tissues culture was markedly(p<0.05) increased in MF diets, especially in soybean oil group. The lipogenic activity in liver tissues culture of MP(meal feeding+palm oil) and MHS(meal feeding+hydrogenated soybean oil)group was significantly (p<0.05) higher than that of AP(ad-libitum+palm oil) group and AHS(ad-libitum+hydrogenated soybean oil) group(p<0.05). Rats fed ad-libitum+beef tallow and fed meal feeding+beef tallow showed significantly(p<0.05) higher lipogenesis than the other groups. It was apparent that the lipogenic activity in liver tissues culture was not affected by dietary lipid sources and meal frequency. Lipolytic activity in liver tissue culture was significantly(p<0.001)different with meal frequency; MF group was higher than AL group, but was not greatly affected by dietary lipid sources. In the in vitro studies with adipose tissue, MF diets increased the lipogenic activity and inhibited the lipolytic activity in adipocytes. The lipogenic activity in adipocytes was significantly (p<0.001) different with dietary lipid sources and found to be beef tallow group was the higherst, but the sources of lipid in the diet did not exert any effect on the lipolytic acitivity.

This study aimed to investigate the interactive effects of individual's cultural disposition (individualism, collectivism, horizontal disposition and vertical disposition) and cognitive style (analytic vs. holistic thinking) combination on differences in global precedence. For this purpose, the participants were divided into 4 different cultural disposition groups based on Singelis et al.'s(1995) INDCOL scale, and 2 cognitive style groups based on Choi et al.'s(2007) AHS, and required to respond selectively to global or local property of two types of compound stimuli (compound figure and compound letter). Reaction time and error rates for both global or local property were analyzed and compared as the dependent measurement. The results can be summarized as followings. First, faster responses were observed in compound figure condition than in compound letter condition, and to global property than to local property. Second, contrasting to individualism-cognitive style or horizontal disposition-cognitive style combinations, significant interaction effects both between collectivism and cognitive style, and between vertical disposition and cognitive style on global/local processing were found. This result indicated that combinations of collectivism-holistic thinking and vertical disposition-holistic thinking can induced larger global precedence effect than other combinations of cultural disposition and cognitive style.

Anticonvulsant hypersensitivity syndrome (AHS) is an uncommon, but potentially fatal and mutilsystemic disorder that occurs after exposure to the arene oxide-producing anticonvulsants-carbamzepine, phenobarbital and phenytoin. The multisystemic reactions include fever, skin eruptions, lymphadenopathy, hematologic abnormality and hepatitis. The diagnosis of AHS is made by history of drug exposure and clinical course. No specific treatments are proved as benefit except discontinuing the offending drug and trying the steroids in some severe cases. We report a case of carbamazepine induced anticonvulsant hypersensitivity syndrome characterized by skin rash, eosinophilia, subcarinal lymphadenopathy and eosinophilic pneumonia. The patient was resolved completely after only discontinuing carbamazepine.

Changes in the characteristics of dissolved organic matter was studied at selected stations in the Nakdong river basin using physical and chemical methods. Characteristics of dissolved organic matters were analysed and assessed. Production of disinfection byproducts were also investigated. Distribution of the organic compounds according to the Molecular weight(MW) indicate that MWs higher than 100K were highest with cattle excrement wastewater and MW between 100-10K were highest with waters from forest streams. Low MW compounds (Jess than 1K) were highest with the effluents from environmental facilities. Results of resin fractionation study show that acidic hydrophobic substances(AHS) were dominant in many stations. The values were higher in the samples from mainstreams and sidestreams where the influence of organic matter is higher than the water from environmental facilities. Hydrophilic neutral substances(HoN) such as hydrocarbon, pesticides and detergents were higher in the wastewater treatment facilities. HoN values of water from the forest streams were 4.7% indicating there is no synthetic pollutant.

Background: Cervical cancer is the second most common cancer among women worldwide. Failure to prevent cervical cancer is partly due to non-participation in regular screening. It is important to plan and develop screening programs directed towards underscreened women. In order to identify the factors associated with underscreening for cervical cancer among women, this study examined Pap test participation and factors associated with not having a time-appropriate (within 3 years) Pap test among a representative sample of women in Ontario, Canada using Canadian Community Health Survey (CCHS) data. Materials and Methods: Univariate analyses, cross-tabulations, and logistic regression modeling were conducted using cross-sectional data from the 2007-2008 CCHS. Analyses were restricted to 13,549 sexually active women aged 18-69 years old living in Ontario, with no history of hysterectomy. Results: Almost 17% of women reported they had not had a time-appropriate Pap test. Not having a time-appropriate Pap test was associated with being 40-69 years old, single, having low education and income, not having a regular doctor, being of Asian (Chinese, South Asian, other Asian) cultural background, less than excellent health, and being a recent immigrant. Conclusions: Results indicate that disparities still exist in terms of who is participating in cervical cancer screening. It is crucial to develop and implement cervical cancer screening programs that not only target the general population, but also those who are less likely to obtain a Pap tests.
