  • Beverages using mountain edible herbs(MEH) were formulated by determining optimum ratio of juices of MEH to several other ingredients. Fermented beverages were made by mixing juices(1 volume) fermented with Lactobacillus helverticus with syrup(3 volumes), followed by homogenization and flavoring . The general analysis and quality change of the beverages during storage were Peformed. The analysis of the beverages showed that the pH of Synurus deltoides and Cirsium sctidens were 3.8 and 3.7, titratable acidities were 0.50 and 0.49, optical densities were 1.201 and 1.119, respectively, The pH and color were not significantly changed when Synurus deltoides and Cirsium sctidens were stored at room temperature and 37$^{\circ}C$ for 6 months. The pH of Synurs deltoides beverage ranged 3.95~3.96 and pH of Cirsium sctidens was 3.83~3.95 at room temperature and 3.87~3.98 at 37$^{\circ}C$, respectively. The analysis of fermented beverages showed that pHs of Synurus deltoides and Cirsium sctidens were 3.65 and 3.70, titratable acidities were 0.57 and 0.60. Solids-non-fat were 3.2 and 3.1, and total counts of lactic acid bacteria were 2.5$\times$10$^{8}$ and 4.0$\times$10$^{8}$ , respectively. The changes of pH and titratable acidities stored at 4$^{\circ}C$ for 15 days were 3.39~3.56 and 0.61~0.81 for Synurus deltoides and 3.48~3.67 and 0.60~0.78 for Cirsium sctidens, respectively.

  • For a microbial control of a plant pathogenic Pseudomonas syringae, Bacillus sp. strain BT182-3 was isolated. The strain BT182-3 had a growth inhibition against P. syringae not only on agar plate but also on cultured broth. After heat treatment at $40^{\cird}C$ and $80^{\cird}C$ for 30min, the lytic substance from the strain BT182-3 had about 52% remaining activity and 17% remaining activity, respectively. The optimal pH and temperature of the lytic substance was 6.0 and $28^{\cird}C$, respectively. Germination ratio of healthy radish seeds was 87% at $25^{\cird}C$ for 5 days in 0.8% saline, and that of the radish seeds infected with P. syringae was 67%, while that of the radish seeds treated with cultured broth of the strain BT182-3 was 90%. The 5-days healthy radish seedlings were 3.90cm at high and the seedlings infected with P. syringae were 3.06cm at high, while the seedlings treated with cultured broth of the strain BT182-3 were 4.30cm at high. The growth of the radish seedlings infected with P. syringae was inhibited after cultivation for 40days on pots, while the growth of the infected radish seedlings with P. syringae was recovered at stem length, root length and total weight at the same as the healthy seedlings after treatment of a lytic substance from the strain BT182-3.

  • In this study the levels and influencing characteristics of maternal identity and self confidence for caring the baby were identified during the immediate postpartum period. 114 primiparous women who delivered vaginally normal baby participated in the survey from August 1 to October 31, 1996. SD scale was to measure maternal identity which consisted of 11 items for mother and 6 items for baby. Likert scale was to measure self confidence for caring the baby (38 items). Cronbach's alphas for evaluating internal consistency as follows : .86 for maternal identity and .96 for self confidence scale for caring the baby. The study showed these results : 1. Mean score of maternal identity(82.03 : 52.65 for mother, 29.38 for baby) was considered relatively low. 2. Mean score of self confidence for caring the baby(113.91) was considered relatively low. 3. There were significant influencing characteristics of primiparous to maternal identity : age(total ; F=3.53, p=.0329, for mother ; F=2.60, p=.0719, for baby ; F=3.12, p=.0481), prenatal infant care preparation(total ; t=2.31, p=.0306, for mother ; F=2.62, p=.0160), knowledge about infant care during the hospitalization(for baby ; F=3.94, p=.02222), colostrum feeding(total ; t=1.95, p=.0541, for baby ; t=2.71, p=.0080), frequency of breast feeding during the hospitalization(for baby ; F=3.91, p=.0228)and feeding type after discharge(for baby ; F=3.18, p=.0456). 4. There were significant influencing characteristics of primiparous to self confidence for caring the baby : routine husband support(F=6.09, p=.0031), prenatal infant care preparation(t=2.04, p=.0574), knowledge about infant care during the hospitalization(F=3.15, p=.0467), education of breast feeding during the hospitalization(t=-1.79, p=.0850). 5. Correlation between maternal identity and self confidence for caring the baby was r=.37608(p=.0001). This study implies that special education programs for primipara are needed. For the future, this study suggest that maternal role variables need to be monitored through the home visiting follow up. Also intervention programs related to prenatal care, discharge education, home visiting follow up need to be developed and then evaluated their effectiveness.

  • The purpose of this study was to determine the factors for professional consciousness of caregivers and provide basic data that could help develop a intervention to promote their professional consciousness. For this descriptive research, a survey was conducted to collect data from 110 caregivers in G City for six weeks in September 2019. Descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression were used. They scored 3.41 for calling and 3.23 for Communication Competence and 4.12 for job satisfaction. Professional consciousness was positively correlated with job satisfaction (r=.636, p<.001) and calling (r=.356, p<.001) and Communication Competence (r=.378 p<.001). job satisfaction (B=.329, p<.001), followed by Communication Competence (B=.216, p<.001) and calling(B=.165, p=.002), had the strongest impact on professional consciousness, accounting for 57.5% in general. It is necessary to give job satisfaction reinforcement training constantly in long-term care givers. It is also necessary to conduct education and research that can promote professional consciousness.

  • We have previously reported the role of miR-217 in anti-cancer drug-resistance. miRNA array and miRNA hybridization analysis predicted miR-30a-3p as a target of miR-217. miR-30a-3p and miR-217 formed a negative feedback loop and regulated the expression of each other. Ago1 immunoprecipitation and co-localization analysis revealed a possible interaction between miR-30a-3p and miR-217. miR-30a-3p conferred resistance to anti-cancer drugs and enhanced the invasion, migration, angiogenic, tumorigenic, and metastatic potential of cancer cells in CAGE-dependent manner. CAGE increased the expression of miR-30a-3p by binding to the promoter sequences of miR-30a-3p, suggesting a positive feedback loop between CAGE and miR-30a-3p. miR-30a-3p decreased the expression of p53, which showed the binding to the promoter sequences of miR-30a-3p and CAGE in anti-cancer drug-sensitive cancer cells. Luciferase activity assays showed that p53 serves as a target of miR-30a. Thus, the miR-30a-3p-CAGE-p53 feedback loop serves as a target for overcoming resistance to anti-cancer drugs.

  • This descriptive study was under taken to explore relationships among the quality of life, health locus of control and perceived state of health persons with cancer to contribute theoretical understanding about these phenomenon of interest to the quality of nursing care. The subjects of this were 200 persons with cancer (100- in patients and 100- out patients), both male and female, between 30 and 59 years of age. Data were obtained using a convenience sample technique from two university hospitals in seoul from August, 1989, to June, 1990. The instruments used for this study were the Quality of life scale developed by Ro, You - Ja and the Health Locus of Control scale developed by Wallston & Wallston. Data were analyzed using a SAS program for ANOVA, t-test, Schefffe test, Pearson Correlation Coefficients and Stepwise multiple regression. The results were as follows : 1. The scores on the quality of life scale ranged from 95 to 191 with as mean of 147.85(range 47 to 235). The Mean scores(range 1-5) on the different dimensions were family relationships 3.50, relationships with neighbours 3.48, self - esteem 3.17, physical state and function 2.99, economic life 2.93 and emotional life 2.91. 2. Significantly higher scores on the quality of life and demographic characteristics were as follows : the quality of life for women(t=2.80, p= .006), for those without complications(t=2.54, p= .013), and for those who perceived their illness as mild(F=4.85, p= .009). Higher scores on quality of life were correlated with the following : 1) emotional state and the age group 50-59(F=3.43, p= .34). 2) economic life and higher income(F=6.72, p= .002), those without complications(t=2.68, p= .00), and those who perceived their illness as mild(F=3.11, p= .05). 3) self-esteem and marriage(F=3.64, p=.028), those without complications(t=2.18, p=.03), and those who perceived their illness as mild(F=7.72, p=.000). 4) physical state and funciton and the age group 30-39(F=4.65, p=.010), those without complications (t=2.00, p=.05), and those who perceived their illness as mild(F=3.38, p=.04). 5) family relationship and those who live with their spouse(t=2.82, p=.005). 3. There was a significant positive correlation between the subjects perceptions of their current state of health and the quality of life score(r=.4364, p=.0001). 4. There was no relationship between Locus of control and quality of life in this sample. 5. Stepwise multiple regression analysis showed that: 1) the perception of current health status was the main predictor and accounted for 20.11% of the total variance. 2) sex and educational level accounted for an additional 21.71% of the total variance. 6. The quality of life and the perception of their current health status of these patients with cancer were generally lower than those of healthy adults as noted in previous studies. In conclusion, the quality of life for these cancer patients was generally low especially in regard to their emotional state. The current perceived state of health, sex, complications and perceived degree of illness were important variables relatiog to quality of life.

  • Scutellaria baicalensis Georgi has been widely used in China for treatment of various diseases. This study investigated the effect of Scutellaria baicalensis Georgi extracts (SBE) against Coxsackievirus B3 (CVB3)-induced myocarditis in vitro and in vivo. In vitro, Hela cells and primary myocardial cells were infected with CVB3 and treated with SBE ($50-800{\mu}g/ml$) and ribavirin ($200{\mu}M$) for 48 h and then determined by CCK8 assay. Real-time PCR and western blotting assays were performed. In vivo, a myocarditis model was induced in male BALB/c mice by injecting CVB3 suspension intraperitoneally for three times, followed by treatment with SBE (400 and 200 mg/kg) and ribavirin (100 mg/kg) for 28 days. SBE ameliorated the cytotoxicity of CVB3 in Hela cells, especially at $400{\mu}g/ml$ (39.93% vs 65.67%, p < 0.05) without influencing cell growth and also significantly reduced CVB3 replication in primary myocardial cells. The levels of AKT, ERK, and p38 were increased after CVB3 infection. SBE could downregulate the expressions of AKT and p38. In vivo, the mortality rate from CVB3 reached to 66.67%, while 10.00% and 23.33% of this came after 400 and 200 mg/kg SBE treatment, respectively (p < 0.05). The CVB3 replication was obviously reduced after SBE administration from day 5. Similarly, the levels of AKT, ERK, and p38 mRNAs and proteins were increased, and SBE suppressed the expression of AKT and p38. Our study indicates that SBE is a promising potent antiviral agent against CVB3-induced myocarditis by inhibition of virus replication via depressing AKT and p38 expressions.
