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.

본 연구는 제1유구치의 조기 상실 시 공간 변화에 대한 분석을 위하여 3-Dimensional Laser Scanner를 이용하여 그 유용성을 평가하고자 하는 예비논문이다. 6세-8세 사이의 제1대구치가 맹출하여 확실한 교합 관계를 이루는 혼합치 열기 어린이 중 편측 제1유구치의 조기 발치가 필요한 6명의 발치 전 후의 모형을 이용하여 다음과 같은 결과를 얻었다. l. 유구치 공간변화는 상악은 실험군과 대조군 모두 현저한 감소를 보이지 않았고, 하악은 실험군에서 3명 중 2명에서 공간감소가 관찰되었다. 2. 치열궁 너비,치열궁 둘레는 초기모형과 최종모형에서 비슷한 값을 보였다. 3. 협설측 경사도 변화는 유견치에서는 상하악 모두 특별한 경향을 보이지 않았으며,제2유구치는 상악은 실험군과 대조군이 유사하였고,하악에서는 3명중 2명에서 실험군이 더 큰 설측경사도 변화를 보였다. 제1대구치는 하악에서 실험군이 더 큰 설측경사도 변화가 관찰되었다. 4. 근원심 경사도 변화 측정에서 유견치는 상하악 모두 특별한 경향이 관찰되지 않았고 제2유구치의 경우 하악에서 실험군이 더 큰 근심경사도 증가가 보였다. 제1대구치는 상악에서 실험군,대조군 모두 원심 경사도가 증가되었다. The purpose of this study was to evaluate a 3-Dimensional laser scanner for the space analysis after loss of a primary first molar. Six children with premature loss of a primary first molar were examined using study models taken before and after the extraction. The results were as follows: 1. There was no change in primary molar space after the extraction of a maxillary primary first molar However, 2 out of 3 children experienced primary molar space loss in extraction side of a mandibular primary first molar. 2. Arch width and arch perimeter showed no difference between initial and final model. 3. All primary canines did not show any changes in inclination. Maxillary primary second molars had similar changes in both extraction and control side. However, 2 out of 3 mandibular primary second molars in extraction side showed more lingual tipping compared to control side. Mandibular permanent first molars tipped more lingually in extraction side. 4. In angulation, primary canines showed nothing of significance. Mandibular primary second molars tipped more mesially in extraction side than in control side. Maxillary permanent first molars have increased distal angulation after extraction of primary first molars in both side.

양념에 Leu. mesenteroides, Lac plantarum의 젖산균과 멸치액젓 첨가가 김치 양념의 대장균군 제어, 속성촉진여부 및 관능적 특성에 미치는 영향을 조사하였다. Leu. mesenteroides과 젓갈을 첨가한 경우 초기 숙성이 촉진되나 후기 산패는 완만하였으며 Lac. plantarum의 첨가시에는 초기 숙성에는 큰 차이가 없고 후기 산패가 현저하게 진행되었다. 대장균군은 산도 0.80% 이상에서 사멸되었는데 leu. mesenteroides의 경우가 숙성이 촉진되어 보다 신속히 사멸시켰다. 총균수와 젖산균수는 초기에 starter 첨가구는 10^6CFU/mL 정도인데 반해서 starter를 첨가하지 않은 않은 처리구에서 총균수는 10^6CFU/mL , 젖산균수가 10^4CFU/mL 이었고 숙성 후에는 첨가균이 높은 수준을 유지하였다. 하지만 대체적으로 스타터의 첨가가 숙성 및 대장균에 크게 영향을 주지 못하는 경향으로 동일하게 나왔다. 관능적 특성에서는 Leu. mesenteroides 첨가구가 Lac. plantarum의 경우보다 우수하였다. 한편, 시판 겉절이 김치는 산도가 0.09~0.18%, ph 5.46~5.89, 총균수 2.2×10^6~3.1×10^7CFU/mL, 젖산균수는 2.1×10^4~6.6×10^5CFU/mL, 대장균수는 1.8×10^4~7.1×10^5CFU/mL, 염분 1.89%~2.51%으로 스타터 첨가 겉절이에 비해 ph와 염도를 제외한 품질 특성에서 전반적으로 낮은 값을 나타냈다. This study was performed in order to investigate the effect of Leuconostoc mesenteroides, Lactobacillus plantarum and salt fermented anchovy extracts on Kimchi sauce. The sauce was fermented more rapidly by addition of Leu. mesenteroids or salt fermented anchovy extracts on the early fermentation stage than the control, but it was fermented slowly on the late fermentation stage. When L. plantarum was added to the Kimchi on the early fermentation stage, the acidity of Kimchi didn't show a significant difference from the control, but acidity was remarkably increased on the late stage. Coliform group was disappeared when acidity of sauce was higher than 0.8% during fermentation. It was controlled by Leu. mesenteroides but not by L. plantarum. Total count and lactic acid bacterial count of the sauces with starter were 6.30×10^6~1.0×10^7 CFU/mL and 1.04~2.04×10^6 CFU/mL, respectively, but those of the control sauce were 10^6 CFU/mL and 10^4 CFU/mL, respectively. Those count of the sauce with starter were higher than those of the control sauce on the later stage of fermentation. Organoleptic quality of the sauce with Leu. mesenteroides was superior to that with L. plantarum.

Bacillus cereus KCTC 3674 produced at least two kinds of extracellular proteases. Two major bands of the protease activity with molecular weights of approximately 100 and 38 kDa were obtained after gelatin-SDS-PAGE. The production of extracellular proteases occurred during the logarithmic growth phase and was greatest when cultures reached the stationary growth phase. On the other hand, the growth of B. cereus KCTC 3674 and the production of its extracellular proteases were severely inhibited by the addition of protonophore carbonylcyanide m-chlorophenylhydrazone (CCCP). Thus, it was concluded that the growth of B. cereus KCTC 3674 and the production of its extracellular pretenses were strongly affected by a H+ electrochemical potential.

호중구 감소성 발열을 보인 고형암 환자의 임상양상 및 그람양성균 균혈증의 위험인자

구남수,김준형,최유경,정세진,오형중,윤기태,김연아,신소연,김명수,김영근,박윤선,최준용,송영구,이경원,김준명 대한감염학회 2006 감염과 화학요법 Vol.38 No.5

목적 : 항암요법을 시행받고 호중구 감소성 발열이 발생한 고형암환자에서 임상양상을 분석하고 그람양성균균혈증의 위험인자를 알아보고자 하였다. 재료 및 방법 : 2002년 1월부터 2004년 12월까지 연세대학교 의과대학 세브란스 병원 종양내과에서 고형암으로 진단받고 항암요법을 시행받은 18세 이상의 암환자에서 호중구 감소성 발열이 있었던 288예를 대상으로 하였다. 결과 : 항암요법을 시행받은 고형암 환자 중 288예에서 호중구 감소성 발열이 발생하였다. 이중 원인을 찾을 수 있었던 경우는 130예로 전체 45.1% 이었으며 미생물학적 확인감염(microbiologically documented infection, MDI)은 53예(18.4%) 이었다. 균혈증이 동반된 호중구 감소성 발열의 원인균 분포를 보면 총 53예에서 그람양성균이 27예 분리되어 50.9%를 차지하였고 그람음성균이 25예(47.2%), 진균 1예(1.9%) 순이었다. 그람양성균 중에서 methicillin 내성 포도상구균의 비율은 35% 이었다. 호중구 감소성 발열 환자에서 그람양성균 균혈증의 독립적인 위험인자를 분석한 결과 중심정맥 카테터와 연관된 감염이 있는 경우, 구내 점막염이 발생한 경우, 그리고 피부 및 연조직 감염이 발생한 경우에서 그람양성균 균혈증의 위험이 높았다. 결론 : 호중구 감소성 발열이 발생한 고형암 환자에서그람양성균 균혈증이 가장 높은 빈도를 보였으며 특히 중심정맥 카테터와 연관된 감염이 있는 경우, 구내 점막염이 발생한 경우, 그리고 피부 및 연조직 감염이 발생한 경우에서 그람양성균 균혈증의 위험이 높음을 알 수 있었다. 따라서 호중구 감소성 발열이 발생한 고형암 환자에서 발열 당시에 위와 같은 위험인자가 있을 경우 glycopeptide의 조기 사용을 고려해야 할 것으로 사료되며 앞으로 더 많은 환자를 대상으로 하는 전향적 연구가 진행되어야 할 것으로 생각된다. Backgrounds : Recently, there has been a rise of prevalence of gram positive infection among cancer patients with febrile neutropenia. The proportion of antibiotic-resistant gram positive infection has been growing lately, especially in Korea, where the rate of MRSA infection was over 70%. It brings to careful consideration of early glycopeptide treatment in febrile neutropenic patients if gram positive infection is suspected. Also until now, most studies concerning febrile neutropenic patients were mainly related to hematologic malignancy rather than solid tumor. Materials and Methods : We evaluated clinical manifestations and risk factors for gram positive bacteremia in a cohort of 288 solid tumor patients who were more than 18 years old and had neutropenic fever after chemotherapy from January 2002 to December 2004 at the Department of Oncology, Yonsei Cancer Center, Seoul. Results : We identified the cause of fever in 130 (45.1%) cases, of which 53 (18.4%) cases were blood stream infection. Gram positive organism was isolated in 27 cases which comprises 50.9% of blood stream infections, followed by gram negative organism (47.2%) and fungus (1.9%). A logistic regression analysis revealed that gram positive bacteremia was associated independently with central venous catheter (CVC) infection, oropharyngeal mucositis, skin and soft tissue infection in febrile neutropenic patients with solid tumor. Conclusions : Gram positive bacteremia was common among febrile neutropenic patients in solid tumor and was associated with CVC infection, oropharyngeal mucositis, skin and soft tissue infection. The early use of glycopeptide must be taken into account in such conditions.

CONSTANS activates SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1 through FLOWERING LOCUS T to promote flowering in Arabidopsis.

Yoo, Seung Kwan,Chung, Kyung Sook,Kim, Joonki,Lee, Jeong Hwan,Hong, Sung Myun,Yoo, Seong Jeon,Yoo, So Yeon,Lee, Jong Seob,Ahn, Ji Hoon American Society of Plant Physiologists 2005 PLANT PHYSIOLOGY - Vol.139 No.2

<P>CONSTANS (CO) regulates flowering time by positively regulating expression of two floral integrators, FLOWERING LOCUS T (FT) and SUPPRESSOR OF OVEREXPRESSION OF CO 1 (SOC1), in Arabidopsis (Arabidopsis thaliana). FT and SOC1 have been proposed to act in parallel pathways downstream of CO based on genetic analysis using weak ft alleles, since ft soc1 double mutants showed an additive effect in suppressing the early flowering of CO overexpressor plants. However, this genetic analysis was inconsistent with the sequential induction pattern of FT and SOC1 found in inducible CO overexpressor plants. Hence, to identify genetic interactions of CO, FT, and SOC1, we carried out genetic and expression analyses with a newly isolated T-DNA allele of FT, ft-10. We found that ft-10 almost completely suppressed the early flowering phenotype of CO overexpressor plants, whereas soc1-2 partially suppressed the phenotype, suggesting that FT is the major output of CO. Expression of SOC1 was altered in gain- or loss-of-function mutants of FT, whereas expression of FT remained unchanged in gain- or loss-of-function mutants of SOC1, suggesting that FT positively regulates SOC1 to promote flowering. In addition, inactivation of FT caused down-regulation of SOC1 even in plants overexpressing CO, indicating that FT is required for SOC1 induction by CO. Taken together, these data suggest that CO activates SOC1 through FT to promote flowering in Arabidopsis.</P>

Yoo, So Yeon,Cho, Haeryun,Kim, Yae Young,Park, Ji Hyeon Korean Academy of Child Health Nursing 2020 Child Health Nursing Research Vol.26 No.1

Purpose: This study investigated the relationship of the partnership between nurses and parents of hospitalized children with the quality of pediatric nursing care as perceived by pediatric nurses. Methods: A cross-sectional descriptive study was conducted among 90 nurses. The data collected were analyzed using the independent t-test and the Pearson correlation coefficient. Results: The level of partnership between nurses and parents showed significant differences by nurses' age (t=2.22, p=.029) and marital status (t=2.54, p=.013). The quality of pediatric nursing care was found to significantly differ by the nurses' age (t=2.62, p=.013), marital status (t=4.17, p<.001), whether nurses had children (t=2.53, p=.020), pediatric ward work experience (t=2.43, p=.020), and total work experience (t=2.51, p=.016). The level of partnership between nurses and parents was positively correlated with the quality of pediatric nursing care (r=.48, p<.001). Conclusion: To improve the quality of nursing care for hospitalized children and their parents, it is important to consider the specific characteristics of pediatric nurses, whose clinical skills should be improved.
