  • 본 연구는 유방 전단파 탄성 초음파에서 탄성도 점수와 변형비를 이용한 방법이 양성과 악성병변의 감별진단에 유용한지를 평가하였다. 탄성 초음파를 시행한 224명을 대상으로 하였으며, 유방조직검사 결과를 바탕으로 후향적인 분석을 하였다. 유방 종괴의 양성과 악성에 따른 5단계의 탄성도 점수와의 동질성 비교는 Fisher's Exact test, 변형비와의 차이검증은 Mann-Whitney U test를 실시하였다. ROC 곡선분석을 통해 악성병변의 예측을 위한 탄성도 점수와 변형비의 최적 cut off 값을 결정하였다. 양성과 악성 결절 군의 분류에 따른 탄성도 점수의 동질성 비교와 변형비의 차이검증 결과에서 각각 통계적으로 유의한 차이를 보였으며(p=.000), ROC 곡선분석에서 양성과 악성 결절의 예측을 위한 탄성도 점수와 변형비의 AUC 0.824, 0.806, cut off 값 3, 4.4로 결정되었다(p=.001). 따라서 탄성도 점수와 변형비는 유방 종괴의 감별진단에 도움을 줄 수 있을 것이다.

  • 마이크로어레이 분석은 특이 발현하는 개별적인 유전자보다 유전자 온톨로지(Gene Ontology)와 같이 기능적 분류나 생물학적 경로(pathway)와 관련된 유전자군을 찾아내는 것이 그 해석의 용이성 때문에 최근 더욱 많은 연구가 진행되고 있다. 약물 처리에 의한 생물학적 반응을 연구할 때, 한 유전자군에 속하는 유전자들 각각의 특이 발현 여부의 유의성을 나타내는 $p$-value들을 취합하여 그 유전자군의 유의성을 결정하는 통계 검증 방법을 본 논문에서 소개하였다. 본 논문에 제시된 유전자군 분석(Gene group analysis) 방법은 Fisher's exact test나 permutation test와 같은 기존의 대표적인 방법들보다 더 정확하고 적용범위가 넓음을 실재 생물학 실험 자료의 분석을 통해 보였다. 제시된 유전자군 분석 방법은 SAS 프로그램으로 구현되었고 저자의 홈페이지(http://cafe.daum.net/go.analysis)에서 내려 받아 사용할 수 있다.

  • 본 연구는 D유형 성격에 따른 간호대학생의 자아존중감, 대인관계, 행복 및 대학생활적응을 분석하고 비교하기 위해 시도되었다. 대상은 간호대학생 181명(D유형 성격 대상자 53명, D유형 성격이 아닌 대상자 128명)이었다. 자료수집은 구조화된 질문지를 이용하여 자가보고하도록 하였다. 자료분석은 ${\chi}^2$-test, Fisher exact test 및 independent t-test를 사용하였다. 분석결과, D유형 성격에 따라 자아존중감, 대인관계, 행복, 대학생활적응에서 통계적으로 유의한 차이가 나타났다. D유형 성격 대상자에서 자아존중감은 간호학과 적응 정도, 대인관계는 종교, 행복은 경제상태, 대학생활적응은 종교와 간호학과 적응 정도에서 유의한 차이를 나타냈다. D유형 성격이 간호대학생의 자아존중감, 대인관계, 행복 및 대학생활적응을 낮추는 요인임을 보여주었다. D유형 성격 간호대학생에서 자아존중감, 대인관계, 행복 및 대학생활적응을 높이기 위한 전략이 필요하다.

  • Purpose: To find objective validity of minimal acupuncture using a modified guide tube as a method to verify the effect of acupuncture. Methods: Subjects of this study were participants of a randomized clinical trial which was practiced to verify the effect of acupuncture on postmenopausal hot flash. There were 2 arms of treatment, one's for active acupuncture group(AG) with manipulation and De qi, the other's for minimal acupuncture group(MG) using a modified guide tube which was designed to give minimal stimulation to the patient. After 8 weeks' treatment followed by 4 weeks' observation, participants were asked to fill in self-report forms on their education, previous experiences of acupuncture, original idea on the efficacy of acupuncture and recognition of blinding. Results: 19 participants of 26 in AG and 19 of 26 in MG completed the self-report form. There was no difference between AG and MG in their education(p=0.5976, Fisher exact test) and previous experiences of acupuncture(p=0.9999, Fisher exact test). In their original ideas on the efficacy of acupuncture, most of AG and MG respondents have been thought that acupuncture is very effective or quite effective, and there was no difference between 2 groups(p=0.5065). 16 of 19 in AG and 14 of 19 in MG believed that they underwent more effective way, there was no statistical difference between 2 groups(p=0.6928, Fisher exact test). Participants believed in undergoing more effective way not because they recognized treatment method, but they were satisfied with the effectiveness of treatment retrospectively. Conclusion: As the result of this study, these authors suggest that minimal acupuncture using a modified guide tube is acceptable as a method to verify the effect of acupuncture in acupuncture-familiar Korean culture. Also further studies on the stimulation-specific effect of minimal acupuncture are demanded.

  • This study analyzed home environment, self-efficacy and parents' child rearing attitudes of disruptive children and of cooperative children in the classroom. Participants were 322 children(11-12 years of age) and 49 teachers. Instruments were four kinds of questionnaires. Data were analyzed by T-test and Fisher's exact test. Results of between group differences in parents' academic backgrounds showed more parents of cooperative children had completed high school. Disruptive children's mothers were more occupied outside the home; cooperative children's mothers engaged in more housework at home. Disruptive children's perceptions of their economic status were lower than cooperative children's perceptions. Results of comparison of general self-efficacy, scholastic self-efficacy, and home environment showed that disruptive children were statistically lower than cooperative children on all sub-variables.

  • Objectives : This study identified the effects of the acupuncture associated with successful cessation at a smoking-cessation clinic of public health center in an urban area. Methods : The subjects of this study were 1121 patients to the smoking cessation clinic of the Anjung Public Healthcare Center in Pyeongtaek, from June 1, 2007 to December 31, 2008. The 123 patients of them were treated by the auricular acupuncture. The experimental group were treated by the acupuncture, and the control only participated in the smoking-cessation clinic program. The data were analysed by SPSS(version 17.0). Chi-square analysis were conducted to see the different of effects between experimental and control group. Also, to find out the factors that affect the success of smoking cessation, logistic regression and Fisher's exact test were done. Results & Conculusions : 1. As the result of the analysis, it showed that 73.2% of the experimental were able to quit smoking for 4 weeks and 6months. 2. Logistic regression and Fisher's exact test showed that number of Cigarette per day, Nicotine Dependence, CO figure(p=.004<.01), and Number of Acupuncture(p=.000<.001) were the factors that affect the successful smoking cessation. 3. The smoking cessation were more likely to success as patients have lower CO figure(B=-.074), more number of the acupuncture(B=1.718). The more number of acupuncture increased 1 time, the more smoking cessation success did 5.576 times(e$^{(1.718{\times}x)$=e$^{(1.718{\times}1)$ = 5.576). 4. As the result of the analysis between experimental and control group, the success rate have the significance difference(p=.000<.001). 73.2% of the experimental were able to quit smoking, but 45.1% of the control did.

  • Objective : We performed this study to investigate whether the use of closed-suction drainage following microvascular decompression (MVD) causes cerebrospinal fluid (CSF) leakage. Methods : Between 2004 and 2011, a total of 157 patients with neurovascular compression were treated with MVD. MVD was performed for hemifacial spasm in 150 (95.5%) cases and for trigeminal neuralgia in 7 (4.5%) cases. The mean age of the patients was $49.8{\pm}9.6$ years (range, 20-69). Dural substitutes were used in 44 (28.0%) patients. Ninety-two patients (58.6%) were underwent a 4-5 cm craniotomy using drainage (drainage group), and 65 (41.4%) did a small 2-2.5 cm retromastoid craniectomy without closed-suction drainage (no-drainage group). Results : Eleven (7.0%) patients experienced CSF leakage following MVD based on the criteria of this study; all of these patients were in the drainage group. In the unadjusted analyses, the incidence of CSF leakage was significantly related with the use of closed-suction drainage following MVD (12.0% in the drainage group vs. 0% in the no-drainage group, respectively; p=0.003; Fisher's exact test). Those who received dural substitutes and the elderly (cut-off value=60 years) exhibited a tendency to develop CSF leakage (p=0.075 and p=0.090, respectively; Fisher's exact test). In the multivariate analysis, only the use of closed-suction drainage was significantly and independently associated with the development of CSF leakage following MVD (odds ratio=9.900; 95% confidence interval, 1.418 to infinity; p=0.017). Conclusion : The use of closed-suction drainage following MVD appears to be related to the development of CSF leakage.

  • Purpose: To evaluate the effectiveness of an experience-focused prenatal program on stress, anxiety, childbirth confidence, and maternal-fetal attachment for women in their first pregnancy. Methods: The participants were 57 pregnant women at 32 weeks or more of a first pregnancy who agreed to participate in this study. The data were analyzed with descriptive statistics, t-test, $x^2$ test, and Fisher's exact test using the SPSS 21.0 program. Results: The experimental group showed significant differences in stress, anxiety, childbirth confidence, and maternal-fetal attachment from the control group. Conclusion: The four-week experience-focused prenatal program can be used for women in their first pregnancy to reduce their stress and anxiety and to increase their childbirth confidence and maternal-fetal attachment.
