The present study was designed to assess the influence of caeca on the availability of calcium, phosphorus, magnesium, manganese and copper from soybean, sunflower, rapeseed, sesame, fish and meat cum bone meal in adult roosters. The excretion of endogenous origin minerals viz., copper, magnesium, manganese and calcium was significantly (p<0.001) higher in caecectomized than in normal roosters. The difference in the endogenous excretion was 50; 60.45; 40.35 and 29.63 per cent for copper, magnesium, manganese and calcium, respectively, in caecectomized roosters. The caeca played a pivotal role in the reabsorption of endogenous origin calcium, magnesium, manganese and copper. The mechanism of phosphorus absorption by the caecal epithelium was negligible. The caecectomized roosters underestimated the bioavailability of copper in sunflower meal and manganese in almost all the test feedstuffs. The present investigation revealed that the caeca played a critical role in the absorption of minerals from vegetable protein feedstuffs which escape digestion and absorption in the small and large intestinal segments.

Increasing conjugated linoleic acid (CLA) content in dairy products has been a research Interest due to the potential health benefits resulted from consuming CLA. Attempts were made to obtain high level natural CLA containing fatty acid fractions from milk fat through bovine feeding of sunflower oil (SO) and urea fractionation. SO feeding changed the fatty acid profile of milk fat. increasing the CLA content five-fold at eight weeks of trial. Milk fat obtained from S0-fed cows was hydrolyzed to free fatty acids, which were then fractionated with urea at various ratios. The profiles of fatty acids were also greatly influenced by urea fractionation. Long-chain unsaturated fatty acids, Including CLA, were concentrated in milk fat after the fractionation, whereas saturated long-chain counterparts were eliminated. The highest level of CLA was achieved by the fractionation at 2:1 urea/fatty acid ratio (UFR2). CLA level was elevated 2.5-fold, and the Cl8:1/C18:0 fatty acid ratio was increased 120 times after the fractionation. The level of CLA in high CLA-milk fat (24mg/g fat) obtained from the feeding study was further increased through urea fractionation up to 52mg/g fat, 10 folds as high as CLA in the control milk fat (5mg/g fat).

Objectives : Child sexual abuse is a highly prevalent societal problem that cuts across all ethnic, racial, educational, and socioeconomic groups. There has been mounting empirical evidence for the efficacy of manual-based, cognitive behavioral treatment(CBT) for sexually abused children. Therefore, the aim of this review was to address the rationale and efficacy of CBT for sexually abused children, and to introduce a broad outline of a typical CBT program for young people suffering the emotional and behavioral consequences of sexual abuse. Methods : A selective literature review was undertaken. Results : To date, trauma-focused CBT is the most effective treatment for the sexually abused child. The rationale and efficacy of CBT was reviewed and a typical CBT program was outlined session by session. Conclusion : Based on trauma-focused CBT for sexually abused children, the results demonstrate the need for future development of a standard CBT program for the Korean population.

Carrots were deep fat fried with sunflower oil (SO), palm oil (PO), and a blend of palm and sunflower oils (PSO with PO:SO as 2:8 or 4:6) at different temperatures (180 and 190℃) and lengths of time (0.5 to 2.5 min). The quality of deep fat fried carrots was determined by the moisture and fat content, color, conjugated dienoic acid (CDA), hydroperoxide, p-anisidine value, and fatty acid composition. The moisture content of fried carrots decreased with increasing frying time, while the fat content increased. The CDA and p-anisidine values of carrots fried with SO were higher than those fried with PO because of greater unsaturated fatty acids content in SO. PSO was a better choice than SO or PO for deep fat frying carrots in the aspects of oxidative stability and ratio of unsaturated to saturated fatty acids. These results indicate that the quality of deep fat fried carrots depends on the type of oil and frying temperature used, as well as the length of time.

Fatty acid composition of commercial oil were analyzed with gas liquid chromatography. Sesame, perilla, rice bran, sunflower, and soy-bean oil were obtained from the whole sale store of edible oil in market. The fatty acids were methylated with Na-methylate. The fatty acid methylester was charged to the gas liquid chromatography. Sesame were composed of myristic, palmitic, stearic. linoleic acid, and trace of linolenic acid. Rice bran, and soy-bean oil were composed of myristic, stearic, oleic, linoleic, and linolenic acid. Peilla oil was composed of palmitic, stearic, oleic, linoleic, and linolenic acid. Sunflower oil was composed of palmitic, stearic, oleic, and linoleic acid.

The efficiency of three complex surfactants based on sunflower oil and nitrogen containing compounds as corrosion inhibitors for mild steel in $CO_2$-saturated 1% NaCl solution, has been determined by weight loss and LPR corrosion rate measurements. These compounds inhibit corrosion even at very low concentrations. The inhibition process was attributed to the formation of an adsorbed film on the metal surface that protects the metal against corrosive media. The inhibition efficiency increases with increasing the concentration of the studied inhibitors. Maximum inhibition efficiency of the surfactants is observed at concentrations around its critical micellar concentration (CMC). Adsorption of complex surfactants on the mild steel surface is in agreement with the Langmuir adsorption isotherm model, and the calculated Gibbs free energy values confirm the chemical nature of the adsorption. Energy dispersive X-ray fluorescence microscopy (EDRF) observations of the electrode surface confirmed the existence of such an adsorbed film.

In this study, we report genetic characterization of Orobanche cumana, the causal agent of sunflower wilting in Serbia. The genetic diversity of this parasitic plant in Serbia was not studied before. Random amplified polymorphic DNA (RAPD) markers and partial rbcL gene sequences analysis were used to characterize the O. cumana populations at the molecular level. While phylogenetic analyses of RAPD-PCR amplicons were performed using unweighted pair-group Method analyses, rbcL gene sequences were analyzed using neigbor joining method and minimum spanning tree. Molecular analyses of RAPD-PCR analysis revealed high genetic diversity of O. cumana populations which indicated high adaptive potential of this parasitic weed in Serbia. Further analyses of rbcL gene using minimum spanning tree revealed clear differences among diverse sections of Orobanche genus. Although this molecular marker lacked the resolution to display intrapopulation diversity it could be a useful tool for understanding the evolution of this parasitic plant. Our results suggested that O. cumana has great genetic potential which can lead to differentiation of more virulent races which is important for determining crop breeding strategies for their control.

Sunflower oil (SO), canola oil (CO) and frying oil (FO) were used as edible oils in this study. According to the frying number, the extracted oils from French fried potatoes were used as experimental samples. To investigate the relationship between the change of fatty acid composition and the stability of the lipid oxidation during frying, the changes of fatty acid composition and the degree of the lipid oxidation of samples were examined. Acid values and peroxide values were evaluated as the degree of lipid oxidation. The acid values of CO and FO were increased with the frying times. The increased acid values of CO and FO were 0.20 and 0.17 on the basis of initial value at 30 times, respectively, but the acid value of SO was lower than those of CO and FO. The peroxide values of the samples were not increased uniformly with the frying number. As the number of frying times was increased, the fatty acid composition of SO and FO were changed. Namely, the oleic acid composition was decreased, whereas the linoleic acid composition was increased with the number of frying times. The benzo(a)pyrene contents of the extracted oils from French fried potatoes did not change regularly as the frying times was increased.
