Purpose: The purpose of this study was to identify difficulties that working mothers face and solutions to the identified problems. Methods: The study design was a cross-sectional, descriptive survey. A survey with 8 items rated on a 5-point scale (1~5) and 5 open-ended questions was administered to 48 married nurses and nurse aides working in 5 nursing units of a teaching hospital in South Korea in April 2013. Results: The score of satisfaction with childrearing patterns (mean=$3.31{\pm}0.79$) was higher than that of satisfaction with spousal support (mean=$3.08{\pm}0.85$). The score of working mother's turnover intention (mean=$2.40{\pm}1.03$) was lowest among the 8 items, but partners did not want their wives to quit work (mean=$3.60{\pm}1.22$). Satisfaction with company employment benefits for childrearing (mean=$2.90{\pm}0.72$) had the lowest score among the 4 satisfaction types analyzed. The turnover intention and satisfactions with childrearing (r=-.51, p<.001), spousal support (r=-.43, p=.002), supervisor's support (r=-.36, p=.013), and company benefits (r=-.37, p=.009) showed significant negative correlations. Conclusion: According to these results, familial support for childrearing is highly correlated with employed mothers' turnover intention. So improvement of familial support for childrearing will reduce married nurses' turnover intention. In addition, well-organized nursery facilities are recommended for enabling working mothers to continue their careers. Furthermore, more family-friendly welfare policies such as a flextime systems or compulsory paternity leave should be reinforced in the workplace.

Background: To investigate political participation by dental hygiene students and analyze the differences therein based on the learning efficacy of dental hygiene policy. Methods: A total of 239 dental hygiene students who were expected to graduate responded to the survey. The data were collected online using a structured questionnaire consisting of 6 items on general characteristics, 10 on political participation, and 15 on the learning efficacy of dental hygiene policy. Statistical analysis was performed using SPSS 23.0. Political participation based on the learning efficacy of dental hygiene policy was analyzed using independent t-tests, ANOVA, and multiple regression analysis (p<0.05). Results: Among the dental hygiene students, 60.7% voted in all three recent presidential, general, and local elections, and 14.2% did not. For political parties supported, 65.7% responded that they had "no supporting party," and 34.3% indicated that they had a "supporting party." In terms of the level of political participation of dental hygiene students (0~50 points), the average score was 25.8 points, with the average passive political participation (0~25 points) score at 15.6 points and the average active political participation (0~25 points) score at 10.2 points. With an increase in dental hygiene policy learning efficacy, both passive and active political participation showed higher scores (p<0.05). Conclusion: Dental hygiene students showed low political participation. The presence of a supporting party, higher voting participation, and higher learning efficacy of dental hygiene policy were associated with higher passive and active political participation. Therefore, to increase this population's interest in political participation, various opportunities for related learning need to be promoted and provided in academia, leading to the enhancement of their political capabilities. In this manner, dental hygienists should expand their capabilities in various roles such as advocates, policy makers, and leaders.

This study was designed to examine nutrition label use, self-efficacy, snacking and eating behaviors of middle school students, and to investigate if these characteristics were different by nutrition label use. A cross-sectional survey was conducted to 348 middle school students in Kyunggi, Korea. About a third of subjects read nutrition labels when they purchased snacks/packaged foods. Most nutrition label users were interested in reading information on calories, fat and trans-fat. Self-efficacy of eating/selecting snacks or general nutrition behavior was moderate (mean score: 44.4 out of 60), with significantly higher score in nutrition label users compared to nonusers (p < 0.001). Nutrition label users felt more confident in 9 items out of 15 items of self-efficacy, such as "taking fruits instead of cookies/candy for snack" (p < 0.001), "choosing milk instead of soft drink" (p < 0.01), "not having snacks after dinner" and "avoiding processed foods for snacks" (p < 0.05). Subjects had snacks 1.3 times a day, and nutrition label nonusers consumed snacks more frequently than the counterparts (p < 0.01). About 55% of nutrition label users and 64.7% of nonusers mainly purchased snacks for themselves (p < 0.05). Commonly purchased snacks by adolescents were ice cream, cookies/chips, breads and ramen. Major considerations in purchasing snacks were taste (46.9%) and price (34.6%). In selecting snacks, the influence of friends and parents was greater than the other sources. Based on eating frequency of snacks, nutrition label users were more likely to consume healthy snacks, such as fruit juices, vegetables, milk, yogurt, and potato/sweet potato than nonusers (p < 0.05). Eating behaviors measured by 15 items scored 33.6 out of 45. Nutrition label users showed better eating behaviors, such as "eating meals slowly", "eating foods cooked with plant oil", and "eating out less frequently" (p < 0.05). Study results showed that majority of adolescents did not read nutrition labels, selected snacks for themselves and had somewhat unhealthy foods for snacks. This study also showed the differences in self-efficacy, snacking and eating behaviors between nutrition label users and nonusers. In nutrition education, it is necessary to stress the importance and skills for reading nutrition labels. It is also needed to help adolescents to select healthy snacks and have desirable eating behaviors, as well as increasing self-efficacy.

The purpose of current study is to investigate the beneficial effect of enzyme (Alcalase) hydrolysates of silk protein in rat. Alcalase-treated silk protein hydrolysate (ATSH) itself did not show any cytotoxicity on the hepatic tissues and blood biochemistry, similar to the normal condition. ATSH played a protective role in tert-butyl hydroperoxide (t-BHP)-induced hepatotoxicity and liver damage. The values of AST (aspartate aminotransferase) and ALT (alanine aminotransferase), which are the indicators of the liver function, were effectively alleviated with the ATSH treatment in a dose dependent manner. The level of Lactate dehydrogenase (LDH) and Malondialdehyde (MDA), which were increased with t-BHP treatment, were significantly reduced by ATSH. High dose of ATSH (2 g/kg) reduced the t-BHP-induced LDH release by 48%. Antioxidant and antioxidant enzymes in liver cells were significantly increased by ATSH treatment in their level and activities. ATSH (2 g/kg) increased glutathione (GSH), an intracelluar antioxidant, by 2.5-fold compared with the t-BHP treated group. The activities of glutathione-s-transferase (GST), superoxide dismutase (SOD), and catalase were also elevated by 38%, 60%, and 45%, respectively, with ATSH (2 g/kg) treatment. The antioxidative effect of ATSH was recapitulated to the protection from t-BHP induced liver damages in hematoxylin and eosin (H&E) staining. Thus, ATSH might be used as a hepatoprotective agent.

국내산 무화과(Ficus carica L.) 중의 조효소를 추출하고 단백분해 조효소의 활성도를 측정하였다. 무화과를 균질화하여 원심분리한 조효소액은 41.15 mM/g fig의 활성을 나타내었으며 단백질 침전 후 조효소액은 17.65 mM/g fig의 활성을 나타내었다. 무화과 조효소액의 기질 특이성은 casein > egg white > BSA > myofibrilar protein > collagen > elastin 등의 순이었다. 무화과 단백질 분해 조효소의 안정성을 보면 pH 6.5~9.0에서 안정하며 pH 2~3의 강산에서는 실활하였다. 또한 $60^{\circ}C$까지는 역가의 변화가 거의 없으며 그 이상의 온도에서는 급격히 활성의 감소를 보이고 있다. 염에 대해서는 0.7 M 정도의 소금 농도에서까지는 비교적 안정하나 그 이후로는 안정성이 떨어지는 것으로 나타났다. 조효소활성에 대한 pH의 영향을 보면 pH 7~8에서 높은 활성을 나타냈으며 근원섬유에 대한 단백 분해능이 pH에 매우 민감한 것으로 나타났다. 무화과 단백질 분해 조효소의 활성은 $40^{\circ}C$ 이후부터 조효소의 활성이 증가하기 시작하여 $60^{\circ}C$에서 최적 활성을 나타내었고 그 이상의 온도에서 점차적으로 다시 감소하였다. $80^{\circ}C$에서도 근원섬유에 대한 단백 분해활성은 최고치에 비해 50% 정도에 해당하는 것으로써 무화과 조효소가 비교적 온도에 민감하지 않았다. 또한 염 농도는 최적 활성에 큰 영향을 미치지 않았다. 무화과를 사용한 sauce 등을 제조할 때에 이러한 특성들을 이해한다면 우리나라 육류 요리용의 우수한 연육제품을 제조할 수 있을 것이다.

Decursin is a major component of the root of Angelica gigas(Umbelliferae), which has been traditionally used in Korea as a tonic and to treat anemia, hemiplegia, and women's diseases. The objective of this study is to identify the anti-cancer mechanism induced by decursin on apoptosis of human leukemia and lymphoma cells. Cytotoxicity of decursin on U937, HL-60, MOLT-4, THP-1 cells showed the significant effects. First of all, $IC_{50}$ of decursin on four cell lines was 27.1, 32.4, 17.4, $15.1{\mu}M$, respectively. So $IC_{50}$ in THP-1 cells was the smallest among 4 cell lines treated with decursin($15.1{\mu}M$). In order to understand the apoptosis-mechanism by decursin, we examined the gene expression of bcl-2(anti-apoptotic), bax(pro-apoptotic) and p53(tumor suppressor)after treating the THP-1 cells with decursin(10, 50 and $100{\mu}M$). It was found bcl-2 gene was decreased dose dependently, the expression level of bax gene of THP-1 cells treated with $100{\mu}M$ of decursin was about 3 times higher than those of control, and p53 gene was increased In the same concentration($100{\mu}M$), p53 gene was increased dose dependent manner. In protein express, bcl-2 and p53 protein showed a tendency to decrease. bax was increased about 4 fold. Therefore decursin is a useful chemotherapeutic agent against leukemia.
