Invasive hemodynamic monitoring has become a valuable assessment parameters in critical care nursing in patients undergoing open heart surgery patients. During cardiac surgery, the Swan Ganz catheter is placed in the pulmonary artery. Critical care nurses routinely obtain cardiac output, cardiac index, and pulmonary arterial pressure in these patients. Traditionally, patients are positioned flat and supine for cardiac output measurement. Numerous studies have dealt with the effects of changing position on the hemodynamic variables. However, there are a few studies dealing with patients who undergo cardiac surgery in Korea. Thus, the purpose of this study was to determine the effects of changing position on cardiac output, PAP, CVP, BP, HR and discomfort in patients after cardiac surgery. A sample of 21 adults who had CABG and/or valve replacement with Swan Ganz catheters in place was studied. The data were collected in the cardiac ICU of a university hospital in Seoul during the period from July 28, 1999 to August 30. 1999. In this study, the independent variable is patient position in the supine, 30 degree, and 45 degree angles. Dependent variables are C.O., C.I., CVP, PAP, MAP, HR and patients' perceived discomforts. Subject discomfort was measured subjectively by visual analogue scale. Other hemodynamic data where collected by the thermodilution method and by direct measurement. The data were analyzed by percentile, t-test, ANOVA, Linear regression analysis using SPSS-/WIN program. The results are as follows : 1) Changes in cardiac output were absent in different angle positions, 0, 30. 45 degrees(F=.070, P=.932). Changes in cardiac index were absent in different angle positions, 0. 30, 45 degrees(P>.05). 2) Changes in central venous pressure were absent in different angle positions, 0, 30, 45 degree(P>.05). 3) PAP had no change in different angle 0, 30, 45 degree positions; systolic PAP(P>.05), diastolic PAP(P>.05). 4) Changes in systolic blood pressure were absent in different angle positions, 0, 30, 45 degree(P>.05). 5) Changes in heart rates were absent in different angle positions, 0, 30, 45 degree(P>.05). 6) Patients' perceived discomfort was absent in different angle positions, 0, 30, 45 degree(p<.05). In conclusion, critical care nurses can measure C.O., C.I., PAP, BP, & CVP in cardiac surgery patients at 30 degree or 45 degree positions. This can improve the patients' comfort.

Objectives: Grip strength is a measure for assessing overall muscle strength, muscle mass, and nutritional status, and is a useful tool for early examination of a person's general health. Thus, this study analyzed the association between oral health-related factors and grip strength, using the 6th Korea National Health and Nutrition Examination Survey (KNHANES) data. Methods: Data were analyzed using the IBM SPSS version 25.0 (IBM Co., Armonk, NY, USA) software with a complex sampling analysis of stratified and clustered variables, all with weighted values, applied for every analysis conducted. From the 6th KNHANES data, a total of 26,101 people were selected as the study population. A complex sample generalized linear model analysis was performed for participants' sociodemographic characteristics, health status, use of oral care products, and factors such as adult mastication and speaking habits. Results: Grip strength was found to be higher among men compared to women. Grip strength was the highest in the 20-39 year old group. Furthermore, grip strength was statistically significantly higher among married and employed individuals, and in the right hand (p<0.001). Grip strength was statistically significantly higher among people who perceived themselves to have good health and among those who did not have health-related problems in the past two weeks (p<0.001). It was also higher among those who used interdental brushes and electronic toothbrushes (p<0.001), but decreased with greater discomfort in mastication and speaking among adults (p<0.05). Conclusions: Grip strength was found to be associated with oral health-related factors and therefore, these could be helpful tools in evaluating both general and subjective health statuses. In general, oral care products are small in size with oral care involving the use of hands and certain precise motions and actions to remove foreign substances in the oral cavity. As shown in the findings, grip strength declines with increased age and as a result, the use of oral care products should be strongly recommended in order to promote better general health.

임신 중 임부가 경험하는 스트레스는 출생하는 신생아에게 부정적인 영향을 미치는 것으로 알려져 있다. 임신부의 심리사회적 안녕이 중요함에도 불구하고, 국내에서 임부의 스트레스를 측정하는 도구는 매우 부족한 상태이다. 본 연구는 1984년에 개발되어 사용되고 있는 26문항의 안황란의 임부스트레스 측정 도구의 신뢰도와 타당도를 확인하기 위해 수행하였다. 산전교육에 참석하는 200명의 임신부를 대상으로 임부스트레스, 우울과 일반적 특성에 대한 질문으로 구성된 설문지를 사용하여 2013년 3월과 5월에 자료수집을 하였다. 주요인 성분분석과 확인적 요인분석으로 구성타당도를 검증하였고, 우울점수와의 상관관계분석으로 동시타당도를 검증하였다. 원도구의 탐색적 요인분석 결과, 6개 문항이 제외되고, 5개 요인(신체적 불편감, 태아, 양육, 배우자 관계, 가사일)이 추출되었고, 57.25%의 설명력을 보였다. 도구의 모형 적합도 지수는 수용할만하였으며, Cronbach's alpha는 .89였다. 우울점수와 상관관계는 유의하게 나타났다(r=.48, p <.001). 본 연구에서 시대적 변화를 반영하여 제시한 20문항의 임부스트레스 도구는 산전 진찰과 간호사정에서 임부의 스트레스 정도를 측정하는데 유용하게 사용될 것으로 기대된다.

冲动购买是指一个没有预先购物意向的立即购买. 以往对冲动购买的研究主要集中于和营销组合变量, 环境因素, 消费人口和特征相关的因素. 在以前的研究中, 营销组合变量如产品种类, 产品类型和氛围, 包括广告, 优惠券, 销售活动, 促销刺激销售点, 和媒体格式都已被用于评估产品信息. 有些作者还着重围绕消费者的情境因素. 如信用卡的使用, 时间, 产品运输性, 发现购物同伴的存在和数量对冲动购买/冲动趋势有积极的影响. 研究也已评估了个体特征的影响, 如年龄, 性别, 以及消费者的教育程度, 以及拥挤的感知, 刺激和接触的需要等因素对冲动购买的影响. 概括来说, 以前的研究发现所有的产品都可以被冲动地购买(Vohs and Faber, 2007), 即环境因素可以影响或至少促使冲动购买行为. 最近新的分销渠道的推出, 例如家庭购物渠道, 折扣店和网上商店, 这些24小时都营业的形式增加了冲动购买的可能性. 然而, 以前的文献重点关注情境和营销变量, 因此这些研究所考虑的消费者的主要特征仍然是缺乏的. 为了弥补这个缺陷, 本研究根据研究的第三个惯例并关注个体特质变量, 这些是很少被研究的. 更具体地来说, 本研究探索了冲动购买趋势对冲动购买行为是否有积极的影响, 并评估了消费者特点例如认知闭合需要(NFCC), 心理健康和人际敏感性是如何影响消费者冲动购买的趋势. 这项调查结果显示, 消费者的情感冲动, 对冲动购买行为产生积极的影响, 而认知冲动并没有对冲动购买行为的影响. 此外, 情感冲动购买倾向是被认知闭合需要的构成因素所推动的, 如果断和模糊不适; 心理健康, 如环境控制和生活的目标, 以及规范和信息的影响. 此外, 认知冲动倾向是被认知闭合需要的构成因素所驱动的决断, 模棱两可的不适和密切的态度, 心理健康和环境控制, 以及规范性和信息的影响. 本研究具有重要理论意义. 第一, 情感冲动对冲动购买行为有巨大影响. 以前的研究根据情感和流动理论提出, 低到中等程度的冲动是自我控制减少或自我监管机制失败所造成的. 本研究证实了上述观点. 二, 本研究通过确认冲动购买趋势可以看做是情感和认知两个维度的二维概念, 并说明冲动购买行为主要是由情感冲动解释, 而不是认知冲动. 第三, 目前的研究有新的概念, 如在本研究的模型中作为潜在影响因子的心理健康和认知闭合需要, 从而对现有的文献做出了贡献. 通过多维概念例如心理健康和认知闭合需要, 有关消费者信息过程的多个方面可以被评估. 第五, 本研究通过确定规范和信息这两个竞争路线扩展了现有的文献. 规范影响发生在个人符合别人的期望或提高他们的自我形象时. 而信息的影响发生在个人搜索来自他人知识信息和观察他人行为之后的推论. 本研究显示了这两个相互竞争的社会影响力的路线, 可以归因于不同影响力的来源. 目前的研究也有许多实际的启示. 首先, 它表明, 公司应该更多关注其首要的目标, 有情感冲动的消费者. 这一方面公司可以创造更振奋精神的购物环境. 二, 目前的结果表明, 认知闭合需要与认知方面的冲动有密切相关的. 这些人是被不经意的想法所驱动的, 而不是感觉或兴奋. 在购买点理性的广告会吸引这些客户. 第三, 容易受规范性影响的消费群是另一个潜在的目标市场. 零售商和制造商, 通过宣传其产品和/或可用于识别或符合愿望组在对他人的期望的产品服务. 但是, 作为一个细分市场, 零售商应避免目标消费群易受信息的影响. 这些人对有关购买的产品服务进行了广泛的信息搜索, 因此更详细, 长期理性的广告信息可以内化这些消费者的思想过程. 本文的结果有几个原因应慎重解释. 这项研究采用了数量较少的便利样本, 而且只调查了两个维度的行为. 为此, 今后的研究应包括更多样化特点和衡量行为的不同方面的样本. 未来的研究还应该调查与情感作用理论密切相关的个性特征. 在以后的研究中, 特征变量会是很另人感兴趣的领域, 如感觉的好奇, 人际敏感性的好奇心, 和气氛反应.
