This study investigated the effect of olive oil substitution ratio on physicochemical quality of pork patty. Five treatments were performed as follows: control (T0, 20% pork fat), T1 (pork fat 15% and olive oil gel 5%), T2 (pork fat 10% and olive oil gel 10%), T3 (pork fat 5% and olive oil gel 15%), and T4 (olive oil gel 20%). The moisture increased and fat amount was decreased in proportion to olive oil substitution ratio. The L* and a* values were highest levels in raw and cooked pork patty of T0, and the b* value was highly enhanced in of cooked pork patty of T4. The water holding capacity, moisture and fat retention were significantly increased, and the cooking loss, diameter reduction and shrinkage ratio were decreased by olive oil substitution ratio. The hardness, springiness and chewiness showed the highest level in T4, and the cohesiveness and gumminess were highest in T0. The reduction ratio of cholesterol in T1, T2, T3 and T4 were 13.8%, 21.6%, 34.5% and 49.0%, respectively, indicating that the content was lowest level in T4. The palmitic acid was the most abundant saturated fatty acid, and the oleic acid was the most abundant unsaturated fatty acid. The unsaturated fatty acid of pork patty was increased in proportion to olive oil substitution ratio. Therefore, the olive oil gel substitution of low-fat pork patty results in a positive effect on the physicochemical qualities due to reduced cholesterol and saturated fatty acids.

Seungmagalgeuntang (SG) is broadly used in traditional Oriental medicine especially in Korea, China, and Japan, for its many pharmacological effects. This study was carried out to investigate the antioxidative, antimicrobial, and anticytotoxic activities of SG and fermented seungmagalgeuntang (FSG). DPPH radical scavenging activities of SG and FSG were 70% and 74%, respectively, which increased slightly by fermentation. Nitrite scavenging activities were strongly altered at pH 1.2, (36.4% in SG and 38.3% in FSG) by addition of $200{\mu}g/g$. Superoxide dismutase-like activities were from 21.5% to 23.3% at a concentration of 0.4 mg/mL, and the highest value were observed in FSG. Total flavonoid contents of SG and FSG were 47.1 and $52.1{\mu}g/L$, respectively which shows an increase upon fermentation. In the antimicrobial activity test, $MIC_{50}$ values of SG and FSG were $800{\mu}g/mL$ for Candida albicans and 3,200 and $1,600{\mu}g/mL$ for Staphylococcus epidermidis and Staphylococcus aureus, respectively. Antibacterial effects were higher in FSG compared to SG. Anticytotoxic cadmium toxicities ranged from 63.5% to 76.1% at $10{\mu}g/mL$ of SG and FSG, and the highest value was observed in FSG. In the sensory evaluation, color, flavor, and overall preference values were higher in FSG.

The study aims to determine the status of oral health of mental illness patients and establish the preliminary data. The examinations and questionnaire survey were done 92 psychiatric patients to measure sociodemographic characteristics, decayed, missing and filled teeth (DMFT) index, patient hygiene performance (PHP) index, community periodontal index of treatment need (CPITN). Result of the missing teeth index in the state of oral health was higher in the hospital group (6.42) while the filled teeth index was higher in the center group (4.78). In the DMFT index, mental illness patients were higher than the national sample. The oral health status of medical aid recipients was poorer as the subjects were older and less educated (p<0.05). The PHP index was 3.41, close to the bad oral hygiene state. The hospital group (81.7%) required higher need for periodontal treatment. The periodontal health state was much poorer especially when the subject was in the age of 40's and 60's, received less education, and had no family (p<0.05). $CPITN_3$ was higher in the hospital group (13.3%) than the national sample (5.7%). The mental illness patients were socially vulnerable, therefore oral health care program should be needed and age, education level, health insurance type, presence of family and other factors needs to be considered in this approach.
The excellence of pigmented rice with respect to its nutritional composition was proven and the physicochemical properties of five kinds of rice (Jindo black rice, Jindo jeongmi, Boseong black rice, red rice, and green rice) were compared. The crude protein content of black rice harvested in Boseong (10.15%) were higher than that of the other varieties. The crude fat contents of pigmented rice (black, red, and green) were higher than those of polished rice (Jindo-jeongmi and black rice). Boseong black rice had the highest crude fat content. The major free sugar types in the rice varieties were maltose and glucose. The major mineral contents of the unpolished rice (pigmented rice) varieties were as follows: of P, 361.32~570.11 mg%; K, 196.63~210.04 mg%; Mg, 104.11~128.02 mg%; Na, 2.49~8.14 mg%; and Ca, 12.10~16.82 mg%. The major fatty acids in the five kinds of rice were linoleic acid, oleic acid and palmitic acid. The fatty acid contents of the rice varieties did not differ significantly. The black rice (Boseong) had a higher amino acid content than the other varieties. The hunter color values of rice varieties were affected by the colors of tha samples. The L (lightness) value of black rice (Jindo, Boseong) was lower than that of the other samples. The thiamine and riboflavin contents of the red rice (0.48 mg/100 g and 0.14 mg/100 g, respectively) were higher than those of the other varieties (thiamine: 0.36~0.24 mg/100 g and riboflavin: 0.09~0.06 mg/100 g). The hardness of the rice varieties differed significantly (10.75~14.64 kg).
The purpose of this study was to develop a nutrition education curriculum with teacher's guide which includes discretionary activities for obese children. A survey was carried out to investigate the recognition of body image and food behaviors according to the obesity index (mild, moderate, severe) in school children (4~6th grade, 158 boys and 60 girls) who were selected based on a physical examination in May, 2006 in the Gyeongnam province. Next, a nutrition education curriculum with teacher's guide was developed on the basis of the findings from the survey and from preceding researches. The results are summarized as follow. The results of this study showed the existence of some nutritional problems such as overeating, prejudice, skipping meals, snacking patterns, etc, which indicate the need for nutritional management for obese children. Most overweight children (80.3%) showed the most interest in the nutrition education program, particularly with regards to dieting for weight control (64.7%). The developed nutrition education curriculum consisted of 8 main subjects and 13 subtitles. The curriculum was prepared for 13 lessons and included songs and singing, making-up lyrics, games about nutrition, discussions of the experience of eating (satiety, thirst, hunger), debates on dietary habits, writing and others to promote the interest for learning. We aimed to develop this program in an attempt to improve the dietary habits of obese school children. This is very important because once a dietary habit is formed in adults, it is difficult to change and the best adjustable stage is during childhood. Therefore, early nutrition education during elementary school can change and build-up the awareness of health in young elementary school children.
Purpose: To determine the role of radiotherapy for the treatment of portal vein thrombosis (PVT) from hepatocellular carcinoma (HCC). Material and Methods: A retrospective analysis was performed on 70 patients that had been diagnosed with HCC and were treated with three-dimensional conformal radiotherapy (3D-CRT) for the PVT. The radiation dose ranged from 40 Gy to 60 Gy (median dose: 48 Gy) and the biological effective dose (BED) ranged from 31.3 Gy to 78.0 $Gy_{10}$ (median dose: 61.6 $Gy_{10}$). Response was determined by measuring the extent of the PVT on a CT image at 0, 1 and 3 months after completion of the radiotherapy. The median follow-up period was 9 months. Results: The response rate was 47.1% (33 patients), with two patients (2.9%) showing a complete response, 31 patients (44.3%) showing a partial response, and 35 patients (50%) showing stable disease or no response. The 1-year progression-free survival rate was 60%, and the median progression-free survival time was 17 months. The median overall survival time was 11 months, the median survival time in the responders was 15 months and in the nonresponders was 8 months (p=0.032). Four patients (5.7%) had transient liver function impairment during treatment. Radiation induced liver disease (RILD) was observed in only one patient (1.4%). Conclusion: Three-dimensional conformal radiotherapy for the treatment of PVT from advanced HCC was a relatively effective and safe method.
To identify nutritional and therapeutic properties of the new Korean red waxy sorghum cultivar ‘Hwanggeumchalsusu (HGC)’, we assayed the antioxidative effects and neuraminidase inhibitory activity. A methanol and 70% ethanol extract of HGC exhibited strong antioxidative effects (IC50 values of 83.2±2.7 for DPPH) and 85.6±2.4 μg/ml for ABTS) and neuraminidase (ND) inhibitory activity (IC50 values of 1.8±0.1 from extracted with methanol and 3.4±0.1 μg/ml from extracted with 70% ethanol) compared with that of the control, noncolored sorghum cultivar ‘Huinchalsusu (HC)’ (IC50> 200 μg/ml). We isolated nine polyphenols, Gallic acid (1), Protocatecuic acid (2), p-Hydroxy benzoic acid (3), Vanillic acid (4), Caffeic acid (5), Ferulic acid (6), Luteolinidin (7), Apigeninidin (8), Luteolin (9), from the HGC - methanol extract, to determine whether they were the active components Luteolinidin of one kind of polyphenols from the HGC, exhibited significant antioxidative effects (IC50 values of 10.9±0.5 μM for DPPH and 8.6 0.6 μM for ABTS) and neuraminidase (ND) inhibitory activity (IC50 values of 26.3±0.6) showed noncompetitive inhibition model. The binding affinity of the ND inhibitors in molecular docking experiments correlated with their ND inhibitory activities. These results suggest that HGC may be utilized to serve as a potential effective antioxidant and inhibitor of ND.
The purpose of this study was to investigate the effects of the regular Upright Body Type Excercise on posture, muscle strength of leg, lung capacity and depression of people with mental illness. The subjects of this study were recruited from B mental health center (5 years and more mental illness patients, n=19) located in P city. For the exercise group, They were carried out the Upright Body Type Excercise Program during 8 weeks (60 min/time, 3 times/week). They were randomly divided into two groups. Exercise group (n=10) and Control group (n=9). And also, they were agreed with consent forms before the experiments. Research results were as follows. Through the upper body type exercise, there was significantly difference in PEF and FEV1/FVC in the trained group. And also, there was much improved in depression level in the trained group. The change of melancholy feeling before and after the program was not statistically significant. However, because of limitations of sampling size due to the peculiarities of the program participants, in consideration of the limit of statistical validation exists clearly, intended to better understand the subjective experience of attendees, qualitative analyzing(qualitative research) was carried out in parallel. It was conducted a deep interview only person accepted among program participants, thematic analysis, subject analysis tasks to be subdivided by classifying by considering the semantic units of what participants expressed, was thus carried out. It found that the degree of melancholy feeling of mental disorders who participated in the Upright Body Typed Exercise Program was reduced. The course of the experience of change in depression appered the three subjects and six sub-themes such as "the start of the change", "interest of the program", "recognition of the need of the body’s health", "physical health promotion", "recovery of physical function", "negative change of habits (attitude)", "reduction of sense of depression", "confidence that it is possible to", "hope for the future". Therefore, upper body type exercise is much helpful in lung capacity and mental health of people with mental illness. So, this type of exercise mostly needed in the people with mental illness group than the other group for the quality of life.

This study was carried out to examine foodborne pathogenic contamination from 1,080 samples of cooked hams and sausages at 10 Korean processing facilities in 2010. The samples were collected from the six primary and additional sterilization products in same lot. To detect Salmonella spp., Staphylococcus aureus, Listeria monocytogenes and Clostridium perfringens in those products (n=1,080), the domestic standard method for Processing and Ingredients Specification of Livestock Products was used. As a result, Salmonella spp. was not detected in all 636 ham and 444 sausage samples. However, L. monocytogenes was detected in four (0.6%) ham and eight (1.8%) sausage samples from five manufactures. S. aureus was also only detected in 4 (0.6%) ham samples from two manufacturers, and C. perfringens was detected in 3 (0.5%) ham samples from three manufacturers, the contamination levels of these pathogens were less than 100 CFU/g. In conclusion, the results of this study indicate that the additional sterilization step of processing manufacturers could not assist to control the foodborne pathogenic bacteria.

Purpose : The aim of this study was to determine the efficacy of $Synagis^{(R)}$ (palivizumab) in reducing the respiratory syncytial virus (RSV) readmission rate in very low birth weight infants (VLBWI ) and the subgroup that showed the most effective vaccination. Methods : We enrolled 350 VLBWI who had been discharged alive from the neonatal intensive care unit of Samsung Medical Center from January 2005 to December 2007 and were followed up for at least one year. A retrospective study based on medical records was performed for a period of one year after discharge. RSV readmission rate was investigated according to BPD (bronchopulmonary dysplasia, requiring oxygen at postnatal day 28) and $Synagis^{(R)}$ prophylaxis. We categorized the subgroups by the severity of BPD gestational age, and birth weight and compared the RSV readmission rates between subgroups. Results : Eleven VLBWI were readmitted. $Synagis^{(R)}$ prophylaxis resulted in a 86% reduction in the rate of readmission due to RSV infection (prophylaxis group, 0.7% and no prophylaxis group, 5.0%; P =0.02). Readmission rate in BPD patients was also reduced in the prophylaxis group (0.7% in the prophylaxis group vs. 5.2% in the no prophylaxis group, P =0.03). The readmission rate in patients without BPD was reduced in the prophylaxis group (0% in the prophylaxis group vs. 4.9% in the no prophylaxis group, P =1.00), but this was not statistically significant.Conclusion : $Synagis^{(R)}$ prophylaxis was effective at reducing RSV readmission in VLBWI. Its efficacy was verified irrespective of BPD, gestational age, or birth weight.
