Washed rice was coated by spraying aqueous dandelion (Taraxacum officinale) extracts at 20, 30, 40 'Brix and dried at room temperature. The coating procedure was conducted 5 mL/min for 10min. Property changes in the dandelion coated rice and un-coated cooked rice were observed during 2 days of storage. Increasing the coating concentration was associated with lower color values (L, a value) and moisture contents. Sensory and texture properties generally decreased in the cooked rice coated with dandelion more than the control (non-coated rice). But, D-20(20 °Brix of the dandelion concentration) resulted in better textural properties and s ensnry scores for hardness and overall acceptability in cooked rice. Compared to the control, the washed rice roated with 20 °Brix for 0 and 2 days showed better quality in sensory activities, a lower gel consistency and better textural activities. It was concluded that the optimum coating ration of rice and added dandelion extract for cooking were 20 °Brix and 5% respectively, in proportion to the total weight of raw rice.

Background and Objectives: Evidence based practice is a hallmark of professional nursing. However, low levels of research utilization are problematic in nursing. The purposes of this study were to identify the facilitators and barriers to research utilization and to identify factors associated with research utilization among nurses. Methods: A descriptive study was conducted with a sample of 227 nurses in a university hospital located in a metropolitan city. The questionnaire included the Barriers Scale and questions about research activities, research related educational needs, and resources used to obtain information for clinical decision making. Results: The main barriers to research utilization identified by the respondents were: the fact that most research is published in a foreign language; implications for practice are not made clear; the research has not been replicated. The greatest mean score of each of the sub-scales was the communication factor followed by the organization, research, and nurse factors. Nurses who had received education for research methods, statistics, and reference search and who had participated research activities reported lower barrier score than those who did not. Conclusions: Although the nurses perceived the importance of research utilization in their practice, there was a poor application in their work. Decreasing known barriers would facilitate research-based practice. The implications for nursing to decrease the barriers to research utilization are discussed.

Purpose: This study aims to test if the age of pregnant women affects the perception, experience, and attitude towards complementary alternative therapy (CAT), by investigating the perception, experience, and attitude of pregnant women under the age of 35, and above 35 (Advanced Maternal Age). The study will 1) find the general characteristics of pregnant women under and over the age of 35 2) compare the perception, behavior, and experience of pregnant women under and over the age of 35, and 3) find the comparison of the perception, behavior, and experience according to the general characteristics of pregnant women under and over the age of 35. Method: The subjects of this study are composed of 44 women under the age of 35 and 44 women above the age of 35, totaling 88 pregnant women visiting midwiferies, obstetrics and gynecology, and baby fairs in Seoul and Gyeong-Gi area. Data for this study was collected from November 28, 2015 to January 6, 2016 for 40 days. The collected data analyzed mean, standard deviation, t test, ANOVA, and chi-square by using SPSS 23.0. Result Results show that there is a significant difference in the perception, attitude, and experience of the two-sample groups in the use of CAT. The question of “what is most necessary when applying CAT in a hospital clinical environment” for the perception criteria came out with the results of t=9.980, p<.05. For the attitude, results showed that the answers of pregnant women under the age of 35 displayed a more positive attitude towards CAT. (t=2.421, p<.05) Lastly, in the experience section, pregnant women under the age of 35 showed more CAT use than the other sample group. Conclusion Results have shown that there is a difference in the perception, behavior, and experience between the two sample groups. Therefore further research on the efficacy and the adverse effects of CAT needs to be done.

Transmandibular implants are used limitedly such as on remaining symphyseal basal bone of atrophic mandible, on the bony defect of symphyseal area due to trauma or tumor as surgical implants. Among the more recent advances in oral implantology are the Fixed Mandibular Implant (FMI)based on the pioneering studies and clinical applications by Irwin Small of the USA and the development very high success rates for providing attachments and abutments in areas of the oral cavity severely compromised by either atrophy or surgical loss of osseous tissues. We will present a case report of regabilitation of totally edentulous mandible with advanced alveolar atrophy using Fixed Mandibular implant (F.M.I).

폴리(스타이렌-b-아이소부틸렌-b-스타이렌) 삼블록 공중합체 아이오노머의 기계적인 성질

The dynamic mechanical properties of poly(styrene-b-isobutylene-b-styrene) and its sulfonated ionomers were investigated. The triblock copolymer showed a tan δ peak at ca. -25℃, which is ascribed to the T_(g) of polyisobutylene blocks. The copolymer also showed a shoulder on a tan δ curve at ca. 50℃, which is probably associated with crystallization and/or melting of the crystalline polyisobutylene blocks. Above 100℃, the copolymer started to flow. In the cases of ionomers, well developed rubbery plateaus, extended to ca. 150-160℃, were seen in modulus-temperature plots. A tan δ peak for the T_(g) of the polyisobutylene blocks and a shoulder peak were also observed for the tetramethylammonia neutralized sulfonated ionomer. However, the shoulder peak became smaller and shifted to low temperatures, which implies that the ionic interactions in this system reduces the ability of crystallization or/and melting of the polyisobutylene blocks. For the K neutralized ionomer sample, only a tanδ peak for the T_(g) of the isobutylene blocks was seen. This different result in these two ionomers is believed to be due to the difference in the strength of ionic interactions.

The styrene-co-methacrylate ionomers neutralized with Na +, Ba2 +, and mixed cation of both were prepared. The dynamic mechanical properties of two cation-containing ionomers were measured and compared to those of the ionomers neutralized with only one type of cations. We found that in the ionomers with one type of cations the difference in the type of cation does not change the glass transition temperatures. It was found, however, that the cluster Tg of the mixed cation ionomer is lower than that of the single cation ionomers. Thus it was postulated that in the two-cation system the two cations in a solution have sufficient dynamics to form new type of multiplet containing both cations, which may be slightly bigger than that found in the single cation multiplet. The mechanical properties also imply that the strength of ion interactions in the multiplets of the two cation ionomer is thought to be weaker than that of the one cation ionomers. These two effects are believed to contribute the lower in the cluster glass transition of mixed cation system.

유암예후에 영향을 미치는 전통적 3인자로 종양의 크기, 전이액와임파절의 수 및 menopausal status를 들 수 있고, 이 외에 최근에는 면역학과 분자생물학의 비약적 발달로 호르몬 수용체, DNA ploidy, cathepsin D, pS2 protein 및 다양한 oncogene들의 증폭이나 과발현 등이 새로운 독립적 예 후인자로 보고되고 있다. 저자들은 유암 110례의 10년 추적조사 성적을 기반으로 이들 새로운 예후인자중 c-erbB-2 oncoprotein, cathepsin D 및 pS2 protein의 과발현이 전통적 예후인자들과 상관성이 있는지와 독립적 예후인자로서 의의가 있는지를 확인하고자 본 연구에 착수하였다. This study was undertaken to define the prognostic value of the overexpression of c-erbB-2 oncoprotein, cathepsin D and pS2 protein in 40 breast cancer patients. The results were as follows : 1.Overall, 32% of patients were positive for c-erbB-2 oncoprotein. Positive staining correlated with menopause status, tumor size and TNM staging, but not wish axllary nodal status. Although there was apparent difference in cumulative survival rates between positive-and negative-staining groups, it was not statistically significant(p=0.0625). 2.52.5% of patients were positive for cathepsin D. Positive staining did not correlate with menopause status, axillary nodal status or tumor size. There was no statistical difference in cumulative survival rates between positive-and negative-staining groups of cathepsin D. 3.57.5% of patients were positive for pS2 protein. Positive staining did not correlate with menopause status, axillary nodal status, tumor size or tumor stage. There was no statistical difference in cumulative survival rates between positive-and negative-staining groups of pS2 protein.
