Nursing students experienced anxiety and fear of building relationships with psychiatric patients due to lack of professional knowledge about metal illness and skill to take care of the patients. The simulation education is known as an effective teaching-learning method since being performed in a non-threatening environment similar to clinical setting. The purpose of this nonequivalent quasi-experimental study was to identify the effect of simulation on anxiety and self-confidence about the psychiatric-mental health nursing practice. The third year nursing students at a three year nursing program were participated in this study. For the experimental group (N=28) the simulation education using the standardized patient based on the scenario for patients with schizophrenia was performed, and for the control group (N=18), the debated education applying the case study same as for the experimental group was made in the class. Using SPSS, t-test and ANCOVA were analyzed to compare the anxiety and self-confidence between the experimental and control groups. As a result of the study, the anxiety score on psychiatric-mental health nursing clinical practice of the experimental group significantly decreased, compared to that of the control group, but the self-confidence score for the performance of psychiatric nursing care showed no significant differences between the groups. Accordingly the simulation education can be an effective educational method to reduce anxiety about psychiatric-mental health nursing clinical practice for nursing students.

The air texturing공정은 노즐에서 전달되는 초음속 에어기류에 의해 overfeed를 수반하여 yarn속 fiber가 뒤얽혀 loop와 crimp를 발달시키는데, 고강력 고탄성율 고내열성 내절단성 등의 특성을 가지는 아라미드섬유를 에어 가공사로 가공 할 경우 가공 전 필라멘트 상태일 때 보다 표면에 생기는 loop로 인하여 촉감이 좋아지고 또한 타 소재와 접착 시 접착제 담지 성능이 향상 되어 접착력이 상승되고, 이를 통해 보강재로서의 기능이 강화되는 반면 역학물성이 기존의 아라미드 보다 저하되는 약점을 가지고 있어 최근 ATY 공정조건이 ATY 사의 구조와 물성변화에 미치는 영향에 대한 많은 연구결과가 발표되고 있다. 본 연구에서는 Aiki air jet texturing machine에서 $Heracron^{(R)}$ para-aramid(840, 1000d, 1500d)를 사용하여 ATY nozzle의 직경을 0.6, 0.75, 1, 1.2mm로 변화를 주어 12개의 para-aramid ATY 시료를 제조하여 이들의 섬도, 강신도, 초기탄성률, 열수축률 그리고 형태불안정성(instability)등의 물성변화를 분석하여 다음과 같은 결과를 얻었다. 노즐의 직경이 증가함에 따라 사 내의 filament간의 움직임이 자유로워 교락이 증가하고 루프가 형성되어 단위길이 당 mass가 커지므로 섬도가 미세하게 증가하는 것을 볼 수 있다. 또한 직경이 증가할수록 절단강도와 초기탄성률은 감소하고 절단신도가 증가하는 경향을 볼 수 있는데 이는 축 방향으로의 배열이 적어져 하중을 분담하는 portion이 감소하고 사의 loop형성이 많아짐으로서 상대적으로 인장력에 대응하는 fiber의 수가 적어지기 때문으로 사료된다. 이는 현미경 관찰로 확인할 수 있는데 직경이 증가함에 따라 사의 loop의 엉킴이 증가하고 filament가 조밀한 것을 확인할 수 있다. 직경 변화에 따른 건 습열 수축률은 1% 미만의 매우 낮은 값으로 영향을 받지 않는 것을 확인 할 수 있는데 para-aramid의 열적특성의 안정성에 기인하는 것으로 사료되며 ATY의 불안정성은 노즐 직경 증가에 따른 어떤 경향성을 찾아볼 수 없었지만 840d, 1000d, 1500d로 섬도가 증가함에 따라 사의 불안정성이 증가하였다.

A numerical study on combustion instabilities in a model combustor was conducted with various momentum flux ratios. Five ratios are calculated based on an actual operating condition of rocket engine. As momentum flux ratio increases, the spreading angle on the injector outlet decreases. And, as increase of axial momentum flux, pressure fluctuation decreases inside the combustor. By using dynamic mode decomposition method, the acoustic modes inside the combustor are identified. Combustion stabilities are analyzed by comparing the damping coefficient of the 2^nd longitudinal mode.

Purposes: Venipuncture is one of the most painful and frequently performed invasive procedure for children by nurses. The purpose of this study was to investigate the effect of EMLA cream(eutectic mixture of local anesthetics: 2.5% lidocaine and 2.5% prilocaine) to decrease venipuncture related pain and anxiety in children. Methods: A randomized, double blinded, placebo-controlled study was conducted. Sixty children scheduled venipuncture were recruited, and randomly allocated to receive either EMLA or a placebo cream 1 hour before venipuncture. Venipuncture was carried out by one nurse investigator. Pain and anxiety was measured by parent, nurse investigator, and nurse observer. Results: Pain in the EMLA group was significantly lower than that of placebo group. However, there was no significant difference in anxiety score between the EMLA and placebo groups. Local side effect of EMLA cream were negligible. Conclusions: EMLA cream was found to be an effective local anesthetic for pediatric venipuncture pain. Further studies should continue to evaluate the facilitators and barriers of EMLA cream application in pediatric nursing practice.

This Study is aimed at showing the effect of relaxation technique on reduction of anxiety of nursing students in the first clinical practice. The samples of this research were eighty fresh-man students of Dong San Junior College of Nursing. Of them thirty-eight were experimental group and remaining forty-two were control group. This study has been conducted from October 14 to 22, 1985. Subjects in all two groups had measured their trait anxiety, after then, the researcher carried out Byun's relaxation technique with experimental group every other day After the experimental period, subjects in all two groups had measured their state anxiety. The tools of this study were two kinds: Spielberg, Gorsuch & Lushene's STAI, and Byun's relaxation technique. To test the statistical difference in the subjects' trait anxiety, score of lecture in pre-clinical practice and score of practice pre-clinical practice, t-test was performed. To verify the hypotheses, ANCOVA was performed. Results of this study were as follows: The main hypothesis that the nursing students who use relaxation technique will have less degree of anxiety in the first clinical practice than the nursing students who don't use relaxation technique was accepted (P<.005). Conclusively, the researcher thinks that it is necessary that nursing students were prepared with relaxation technique to reduce anxiety in their first clinical practice.
