Purpose: This study was aimed to identify the effects of Self-Foot Reflexotherapy on the Fatigue, Mood and Vital Signs of the Nursing students. Methods: The research design was a quasi experimental, one-group pretest-posttest design. The data were collected from June 15 to August 31, 2008. The one group was consisted of 21 subjects. The instruments used for the study were the Fatigue and Paleasant mood. The data were analyzed by SPSS WIN 12.0 program. In order to compare the effect of the pre-post Foot Reflexotherapy, paired-test and Repeated Measures ANOVA was employed. Results: A significant decrease in fatigue, increase in Mood and Vital signs after providing self foot reflexotherapy was observed. Conclusion: The result suggests that a self foot reflexotherapy could be utilized as an effective nursing intervention to the patients to reduce fatigue, Mood and vital signs.

휴대용 디바이스와 웨어러블 기기의 보편화에 따라 사람들은 자신의 활력 징후에 대한 접근이 간편해졌다. 활력징후는 건강관리만을 목적으로 활용되고 있으며, 건강관리 이외의 목적으로 활용하는 경우는 발견 할 수 없다. 본 논문에서는 영상매체를 관람한 사람의 감정 상태를 스마트밴드에서 제공하는 활력징후를 이용해 판단하는 웹 사이트를 제안한다. 베스트씬 웹 사이트에서는 영상매체를 본 사람의 활력징후의 전체적인 추이와, 여러 사람들의 베스트씬 장면과 특정 장면에 대한 사람들의 활력징후를 확인 할 수 있다. 본 논문에서는 활력징후를 기존의 건강관리가 아닌 다른 방면으로 이용하기 위한 필요성을 인식하였다. 이에 사람들의 활력징후를 받아 감정 상태를 분석하는 연구를 진행하고, 웹 사이트로 구현하였다. 이를 위해, 본 논문에서는 활력징후를 데이터베이스에 저장하고, 저장된 데이터를 바탕으로 알고리즘을 적용 해 그래프를 그려 웹 사이트에 사용자 별 그래프와 전체 사용자의 그래프를 제공한다.

In the advance of computer technology, it is possible to keep all the related informations for monitoring equipments in control and huge amount of real time manufacturing data in a data base. Thus, the statistical analysis of large data sets with hundreds of thousands observations and hundred of independent variables whose some of values are missing at many observations is needed even though it is a formidable computational task. A tree structured approach to classification is capable of screening important independent variables and their interactions. In a Six Sigma project handling large amount of manufacturing data, one of the goals is to screen vital few variables among trivial many variables. In this paper we have reviewed and summarized CART, C4.5 and CHAID algorithms and proposed a simple method of screening vital few variables by selecting common variables screened by all the three algorithms. Also how to develop a logistics regression model on a large data set is discussed and illustrated through a large finance data set collected by a credit bureau for th purpose of predicting the bankruptcy of the company.

본 논문에서는 TMO 실시간 객체 모델을 이용하여 실시간 통신 메시지 서비스를 효과적으로 지원하기 위해 중환자의 실시간 생체정보 전송 시스템을 나타내었다. 또한 분산된 네트워크 시스템에서 TMO 구조를 이용하여 ICU(intensive care unit) 응용 환경에 적용함으로서 실시간 메시지 서비스를 보장하였다. TMO를 이용한 생체정보 파싱 수신 모듈은 ICU의 Central Monitor로부터 수신할 수 있는 Raw Data 형태의 환자의 생체 정보를 생체 정보 웹 뷰어 시스템에서 사용가능한 데이터로 분석할 수 있도록 설계하였다. 실시간 뷰어 시스템은 환자 생체정보에 대한 실시간성과 생체 정보에 대한 데이터의 연속성을 부여하여 베드 사이트의 환자에게서 발생된 모든 생체정보에 의해 환자 관리를 데이터베이스를 이용하여 전산화함으로써 환자의 광범위한 자료 검색이 이루어지므로 원격진료로 활용이 가능하다. TMO 객체 모델을 기반으로 한 실시간 시뮬레이션에서 몇 가지의 TMO 구조의 장점을 가지고 있으며, TMO 객체 모델은 요구 명세서와 설계 사이의 강력한 연관성을 가지고 있다.

본 연구는 실생활에서 가장 많이 접할 수 있는 모바일 전면 카메라를 이용하여 심장박동, 심장박동 변이율, 산소포화도, 호흡도, 스트레스수치, 혈압을 측정할 수 있는 효과적인 방법론을 제시하는 것이 목적이다. Blaze Face를 이용하여 실시간으로 얼굴인식을 진행하여 안면 이미지 데이터를 취득하고 눈, 코 입, 귀의 특징 점을 이용하여 이마를 관심영역으로 지정하며 평균값을 시간 축으로 정렬한 후 생체징후 측정에 이용하였다. 생체징후 측정 기법은 fourier transform을 기본으로 이용하였으며, 측정하고자 하는 생체징후에 맞게 노이즈 제거 및 필터 처리함으로써 측정값의 정확도를 향상 시켰다. 결과를 검증하기 위해 접촉식 센서와 비접촉식 센서 비교를 진행하였다. 분석 결과 안면 이미지를 이용하여 심장박동, 심장 박동 변이율, 산소포화도, 호흡도, 스트레스, 혈압 총 여섯 가지 생체 징후를 추출 할 수 있는 가능성을 확인하였다.

Purpose: This study compared infant mortality and its associated factors between Korean and immigrant women using vital statistics gathered by Statistics Korea. Methods: Birth and death statistics from the period between 2009 and 2019 were extracted from the census of population dynamics data of the Microdata Integrated Service, Korea. Statistical data were derived from a complete survey and infant mortality was analyzed from mortality statistics data. Descriptive statistics were used for comparison. Results: The average infant mortality rate (IMR) of Korean women was 2.7 in Korea, which did not change significantly between 2009 and 2019; however, the IMR of immigrant women increased significantly in 2018 to 4.2 and subsequently decreased to 2.6 in 2019. Moreover, the age of Korean and immigrant women at the time of infant death gradually increased from 31.1 years and 25.9 years in 2009 to 32.8 years and 30.9 years in 2019, respectively. The gestational age was lower for deceased infants born to immigrant women (mean, 31.04 weeks; standard deviation [SD], 6.42; median, 30.00) compared to infants born to Korean women (mean, 31.71 weeks; SD, 6.48; median, 32.00). Immigrant women (91.7%) received slightly fewer antenatal care visits compared to Korean women (93.1%). Conclusion: It is vital to devise a plan to lower the IMR of immigrant women in Korea. Moreover, it is necessary to explore the factors related to infant mortality among immigrant women within the context of Korean societal situation, culture, and home environment.

Purpose: The aim of this study is to evaluate the effect of music therapy according to preferred music and to identify the effect of duration time and starting point of music therapy on anxiety and vital signs in spinal anesthesia operations. Method: These subjects were categorized into three groups based on the order of the date of operation. Data on anxiety and vital signs for this study were collected from them. The collected data were analyzed by $X^2$-test, t-test, paired t-test and ANCOVA. Result: The results of this study showed that preferred music, differences of duration times and starting points of music therapy didn't make significant differences in anxiety and vital signs among the three groups. However for anxiety, there was a meaningful difference within three groups. This result indicates even randomly chosen music by nurses considering the patients' age makes a meaningful difference in anxiety. Conclusion: Based on the results of this study, the conclusion can be made that music therapy is a useful nursing implementation to reduce anxiety in patients undergoing operations with spinal anesthesia.

Purpose: The purpose of this study was to investigate the effects of aromatherapy on stress, fatigue, mood, and vital signs of the nurses in the operating rooms. Methods: The data were collected from September 2007 to February 2008 in the operating room at K hospital located in Seoul, Korea. A total of 48 nurses were recruited. Among them, 25 nurses were randomly assigned to an experimental group and 23 were assigned to a control group. Experimental group was provided with aroma inhalation by necklace which had essential oil mixture of 0.2 cc. For aroma inhalation, Lavender, Zeranium and Mazoram were mixed in ratio of 5:3:2. In order to test the effectiveness of aroma inhalation, the pretest and posttest results for stress, fatigue, mood, and vital signs were compared between the experimental group and the control group. The data were analyzed by unpaired t-test and ANCOVA using the SPSS/WIN 15.0 program. Results: There were statistically significant decreases in the stress and fatigue scores, and increase in the mood scores and showed significant relaxation in the vital signs after the aroma inhalation. Conclusion: The aromatherapy had the positive effects on stress, fatigue, mood, and vital signs.

PURPOSE: The purpose of this study was to investigate the vital capacity and maximal voluntary ventilationin subjects with forward head posture (FHP). METHODS: Twenty-eight subjects participated in this study (normal 14, FHP 14) and were resident in B city. The mean age, height and weight of subjects was 22.80yrs, 169.36cm and 62.79kg. Subjects were asked to breath maximally for FVC and repeatedly for MVV during 12 seconds. The variables of data were collected as follows: Forced Vital Capacity(FVC), Forced Expiratory Volume in One Second($FEV_1$), $FEV_1$/FVC, Maximal Voluntary Ventilation(MVV). Each trial was performed by 3 times and we used the means to analyze the data. The mann-whitney U test and independent t-test were used to compare the vital capacity between normal and FHP subjects. All statistical analyses were performed using SPSS 21.0 for window versionand p-values less than 0.05 were used to identify significant differences. RESULTS: The FVC, $FEV_1$, $FEV_1$/FVC and MVV of FHP subjects were decreased more than that of normal subjects and the difference was statistically significant between two groups. CONCLUSION: The vital capacity of subjects with FHP was generally lower than normal subjects. This study shows that the vital capacityof subjectswith FHP could be decreased due to the bad neck posture that weakens the respiratory accessory muscles of neck.
