Green tea has been known to show beneficial effects on alleviating stress. The present study was conducted to determine the effects of dietary green tea on quality of eggs, during storage, laid by laying hens treated with corticosterone in order to mimic the current practice of the egg market. Hens were fed for 2 weeks one of three diets containing green tea at 0.0, 0.4 or 1.0%. Each dietary group was divided into two subgroups receiving corticosterone at 0 or 30 mg/kg for 1 week. Eggs, laid at 5-7 days following the initiation of corticosterone treatment, were stored at $10^{\circ}C$ for 1 or 5 weeks and then analyzed for egg quality. After 1 week of storage, egg weight was significantly increased by green tea (p<0.025) but decreased by corticosterone (p<0.0001), but no interaction was observed between both. Corticosterone decreased shell color (p<0.0001) but green tea significantly decreased shell strength (p<0.006). Yolk color, albumen height and Haugh unit were not affected by both treatments. After 5 weeks of storage, corticosterone resulted in reduced egg weight (p<0.01) and eggshell color (p<0.001) and increased shell strength, which were not attenuated by green tea. Taken together, the results of the current study show that dietary corticosterone reduces egg quality during storage, which are attenuated in part by dietary green tea.

This study was conducted to identify the Convergence influence of job satisfaction of care service providers on their psycho-social well-being status. A study subjects were 308 care service providers employed in local self-support centers for Social Service in Gwangju, Jeonam Jeonbuk province, from whom data was collected using self-administrated structured questionnaire after regular holiday education. In consequence hierarchical multiple regression analysis, research findings; adjusting general and occupational characteristics, the higher they perceived sub-dimensions of job satisfaction such as relationship with job demands(${\beta}=0.393$, p=.063), clients(${\beta}=0.669$, p=.000), relationship with peers and supervisors(${\beta}=0.229$, p=.068) the better their psychosocial well-being status was. And psychosocial well-being status of those who held certificate of care provider(${\beta}=4.815$, p=.003), helpers for neonate and mother(${\beta}=4.348$, p=.011) were higher than that of those who did not, which reflexed difference in their clients. As a results, promote mental health of care providers, it would be necessary to provide them training programs for facilitating human relationships with clients, peers and supervisors.

The purpose of this study is to determine the possibility of using Plantago asiatica as natural health food source. To accomplish this purpose. the contents of proximate and anti oxidative nutrients of P. asiatica were measured. The contents of carbohydrate. crude protein. crude fat and crude ash are 63.71%, 18.75%, 1.67% and 6.48%, respectively And the calories and total dietary fiber of P. asiatica was 466.71 Kcal. Total dietary fiber was 22.68%, respectively. The contents of essential and non-essential amino acids were 4.815.22 mg and 6.591.04 mg, respectively. The K was the largest mineral followed by P, Ca, Mg, and Na, which means P. asiatica is alkali material. The EDA of P. asiatica was 59.32~70.30%, and the activity was dependent on the sample concentration. Total phenolic content of P. asiatica was $79.65{\mu}g/g$, and total flavonoids content was $4.43{\mu}g/g$. The P. asiatica extract showed the highest reducing power (3.5) at a concentration of 25 mg/mL. Based on the above results, we deemed that the P. asiatica might have potential antioxidant activities. The general nutrients and other antioxidant bioactive materials in P. asiatica were also potential materials for good health food.

Purpose: In this study, we aimed to evaluate the effects of sex-based non-small cell lung cancer (NSCLC) varieties on survival rates. Materials and Methods: A retrospective study was performed in patients with NSCLC who were diagnosed by histological methods between the years 2000 and 2010. A chi-square test was used to compare variables. Overall survival (OS) was estimated by the Kaplan-Meier method. Results: Of the 844 patients, 117 (13.9%) were women and 727 (86.1%) were men. Adenocarcinoma was more common in women than in men (p<0.0001). There were more women non-smokers than men (p<0.0001). There was no statistically significant difference in ECOG PS, weight loss>10%, stage, LDH, albumin and treatment between women and men. Women younger than 65 years (17.0 vs 12.0 months; p=0.03), who had adenocarcinoma histology (15.0 vs 10.0 months; p=0.006) and who had a hemoglobin level ${\geq}12g/dL$ (18.0 vs 12.0 months; p=0.01) were found to have a better median OS rate than men. Median OS rates were found to be 13.0 months in females and 12.0 months in males (p=0.14). Among metastatic patients, the median OS was 11.0 months in females and 8.0 months in males (p=0.005). Among stage IIIB and stage IV patients who had first line platinum-based chemotherapy, the median OS was 17.0 months in women and 11.0 months in men (p=0.002). The response rate of chemotherapy was higher in women than in men (p=0.03). Conclusions: In our study, we found that survival duration is longer and chemotherapy response is better in women with NSCLC who do not have anemia or comorbidities and who are mostly non-smokers with adenocarcinomas. Further studies regarding the causes of these differences may provide clarity on this subject.

This study was undertaken to hemodynamically determine the differences of myocardial protective effect between crystalloid and blood cardioplegic solution. Twenty nine children undergoing cardiac operations due to cyanotic congenital heart diseases were randomized into two groups receiving crystalloid or blood cardioplegia. Cardiac indices and other hemodynamic datum were examined postoperatively. Although there was no statistical differences between groups, postoperative stroke volume indices and left ventricular stroke work indices were slightly better with blood cardioplegia. We also found that postoperative left atrial pressures[p=0.0003], central venous pressures[p=0.004], and heart rates[p=0.014] were significantly lower with blood cardioplegia. The fact that relatively lower ventricular preloads [left atrial pressure and central venous pressure] were required to provide adequate cardiac output in blood cardioplegia group suggested superior myocardial protective effect of blood cardioplegic solution.

It is well known that the denominator of the Dedekind sum s(c, d) divides 2 gcd(d, 3)d and that no smaller denominator independent of c can be expected. In contrast, here we prove that we usually get a smaller denominator in S(H, d), the sum of the s(c, d)'s over all the c's in a subgroup H of order n > 1 in the multiplicative group $(\mathbb{Z}/d\mathbb{Z})^*$. First, we prove that for p > 3 a prime, the sum 2S(H, p) is a rational integer of the same parity as (p-1)/2. We give an application of this result to upper bounds on relative class numbers of imaginary abelian number fields of prime conductor. Finally, we give a general result on the denominator of S(H, d) for non necessarily prime d's. We show that its denominator is a divisor of some explicit divisor of 2d gcd(d, 3).

A bacterum containing antitumor activity was isolated from traditional korean food, Jeotgal. Through the 16s rRNA sequence analysis, the bacterium was identitied as a strain of Bacillus subtilis SW-l. The best culture condition for antitumor activity of the bacterium is 3% of soluble starch and 1 % of yeast extract as corbon and nitrogen sources, respectively. Cytotoxicitic concentrations of the culture supernatant of B. subtilis SW-1 against cancer cell lines, A549 and SK-OV3 were 30 ul/ml and 40 ul/ml, respectively, as $IC_{50}$/ values. In DNA fragmentation assay, the culture supernatant showed the programmed cell death (apoptosis) to cause degrading the chromosomal DNA like ladder. Taken together, the culture supernatant of the B. subtilis SW-1 has some possibility to be used as an antitumor agent.
