People can access to their vital signs easy through portable devices and wearable devices. The vital signs are used only for the purpose of health care, and can not be found when they are used for purposes other than health care. In this paper, we propose a web site to judge the emotional state of a viewer by using vital signs provided by smart bands. On the proposed web sites, user can see the overall trend of a person's vital signs and the vital signs of a person's best scenes and specific scenes. In this paper, we recognized the necessity to utilize the vital signs as an aspect other than existing health care. In this study, we analyzed the emotional state of people with vital signs and implemented them as a web site. In this paper, we store vital signs in a database, apply algorithms based on stored data, and draw graphs to provide user - specific graphs and graphs of all users on the Web site.

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.

The purpose of this study is to present an effective methodology that can measure heart rate, heart rate variability, oxygen saturation, respiration rate, mental stress level, and blood pressure using mobile front camera that can be accessed most in real life. Face recognition was performed in real-time using Blaze Face to acquire facial image data, and the forehead was designated as ROI (Region Of Interest) using feature points of the eyes, nose, and mouth, and ears. Representative values for each channel of the ROI were generated and aligned on the time axis to measure vital signs. The vital signs measurement method was based on Fourier transform, and noise was removed and filtered according to the desired vital signs to increase the accuracy of the measurement. To verify the results, vital signs measured using facial image data were compared with pulse oximeter contact sensor, and TI non-contact sensor. As a result of this work, the possibility of extracting a total of six vital signs (heart rate, heart rate variability, oxygen saturation, respiratory rate, stress, and blood pressure) was confirmed through facial images.

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 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.
