Currently, the ages of the patients visiting dental hospital for dental care are becoming younger and the interest in the treatment for the handicapped and incapable of cooperation children increases. As a method for treatment of these patients, the sedation treatment is considered. A dental sedation using chloral hydrate and hydroxyzine of them were used widely and for a long time. In this study, the samples were consisted of incapable of cooperation or very young children required treatment of restoration under local anesthesia. Then, the vital signs were accessed in pediatric dental sedation using the combination of chloral hydrate and hydroxyzine. As a result of this study, the vital signs were little different in pediatric dental sedation using the combination of chloral hydrate and hydroxyzine. Simply, the respiration rate and pulse rate decreased according to sleeping of patients. Therefore, the sedation using the combination of chloral hydrate and hydroxyzine induced to appropriate sedation in incapable of cooperation or very young children with little effects of vital signs.
The purpose of this study was to investigate the changes in the vital signs and anxiety reactions during scaling to patients who had received the dental hygiene treatment at department of Dental Hygiene in a university. A total of 189 patients were participated in the study. The level of anxiety was assessed through a dental anxiety questionnaire consisting of dental fear survey scale and dental anxiety survey scale. The vital signs were measured before and after scaling. The obtained results were as follows. The level of anxiety before scaling was 2.16 and after scaling was 1.96. This was significantly higher in women. The pulse and systolic blood pressure after scaling significantly decreased from 77.48 times to 74.36 times per minute and from 124.96 mmHg to 122.50 mmHg respectively. These changes are within the normal physiological variations. Individual changes in respiration, pulse, blood pressure, body temperature are affected by age, gender and previous dental experience, but previous scaling experience. The level of anxiety was significantly explained by respiration before scaling and pulse after scaling. As a result, scaling was associated with dental anxiety reactions and changes in vital signs.
Purpose: This study was to examine the effects of noise block on anxiety and vital sign of gynecologic laparoscopic surgery. Methods: The data were collected from March to May 2011. Participants were sixty patients with gynecologic laparoscopic surgery, divided into 30 of experimental group and 30 of control group at C University hospital located in I city. The day before surgery, demographic data, trait-state anxiety and vital signs were measured at ward. After noise block, the data were measured using VAS anxiety and vital signs before anesthesia and in recovery room. And then state anxiety and vital signs were measured in ward after surgery. The data were analyzed by $x^2$-test, t-test, repeated measured ANOVA and Bonferroni comparison method using SPSS/WIN 19.0. Results: After conducting noise block program, the experimental group showed significant decrease in state anxiety and heart rate compared to those of the control group. But there were not significant differences in VAS anxiety, systolic pressure and diastolic pressure between two groups. Conclusion: This program can be regarded as an effective nursing intervention for the management of anxiety with gynecologic laparoscopic surgery.
As small sized bio-sensors and digital yarns are developed, digital wear measuring vital signs can be used for individuals' health, the elderly care and sports activities. This paper discusses a database structure for analyzing stress state, pulses, positions, exercise amount of user based on vital signs measured for 24 hours measured by the wear and GPS information, and a storage for storing XML documents following a standard HL7 meta-model. By analyzing the stored information, the system identifies the stress state and exercise amount of users. Pulses, exercise intensity and emergency situations can be also detected by the system in real time. This paper discusses the implementation of a system enabling to acquire and analyze vital signals to understand user behavior patterns.

This paper describes a compact and novel wireless vital sign sensor at 2.4 GHz that can detect heartbeat and respiration signals. The oscillator circuit incorporates a planar resonator, which functions as a series feedback element as well as a near-field radiator. The periodic movement of a human body during aerobic exercise could cause an input impedance variation of the radiator within near-field range. This variation results in a corresponding change in the oscillation frequency and this change has been utilized for the sensing of human vital signs. In addition, a surface acoustic wave (SAW) filter and power detector have been used to increase the system sensitivity and to transform the frequency variation into a voltage waveform. The experimental results show that the proposed sensor placed 20 mm away from a human body can detect the vital signs very accurately.
In this paper, we present an intensive patient monitoring service through the Internet, which enables medical doctors to watch their patients in a remote site, to monitor their vital signs and to give them some advices for first-aid treatment. The service consists of three service objects: Monitoring Information Service(MIS), Vital Sign Monitoring Service(VSMS) and Multimedia Consulting (MCS). Through the MIS, medical doctors can get information about the patients currently under monitoring, including their names, ages, genders, symptoms, current main complaints and current locations. The VSMS enables medical doctors to monitor in real-time patients' vital signs such as electrocardiogram (ECG), respiration, temperature, blood oxygen saturation (SpO$_{2}$), invasive blood pressure (IBP), and non-invasive blood pressure (NIBP). It also generates alarms when the patients are likely to be in a critical situation. The MCS provides a real-time multimedia desktop conferencing facility for watching patients and instructing attendants to administer some first-aid treatment. We carried out some experiments according to two different scenarios. The intensive patient monitoring service was functioning well in a 100Base-T Ethernet LAN environment.
The purpose of this study was to determine the effects of music therapy on changes in the vital signs of patients about to undergo an operation. The patients listened to the music at a time when they were feeling preoperative anxiety up until the preanesthesia was given in the operating room. The subjects for this study were selected from sixty patients to undergo operations, who were hospitalized at Dong Eui hospital in Pusan city. They were assigned to two groups, thirty to the experimental group and thirty to the control group. The subjects were from 20 years old to 69 years old, and had no other problem except the one requiring the operation, and no premedication. The data were collected during the period from July 1 to September 30, 1993. The method used in this study was to measure state-anxiety on the ward in the morning of the operation, and vital signs immediately before leaving for the operating room. Vital signs were measured immediately before the anesthesia was given and after the experimental group had listened to the music during the ten minutes needed to prepare the operation setting. The control group just waited during ten mimutes. Vital signs were check again before the anesthesia was given. The data were analyzed by descriptive statistics, mean±SD, p-value, and t-test using the SPSS progrom. The results of this study are : 1. Systolic blood pressure taken in the operating room was elevated, over the level measured on the ward, by 5.00 ± 15.26㎜Hg in experimental group and 18.67±14.56㎜Hg in control group. (t=-3.5496, p=.0008) 2. Diastolic blood pressure was elevated by 6.67±12.95㎜Hg in experimental group and 18.67±12. 79㎜Hg in control group. (t=-3.6100, p=.0006) 3. Pulse was elevated by 2.931±9.44 / min in experimental group and 8.03±8.37 /min in control group. (t=-2.2144, p=.0307) 4. Respiration was elevated by 0.60±1.35 /min in experimental group and 1.57±1.48 /min in control group. (t=-2.6409, p=.0106) 5. Body temperature was down by 0.13±1.91'c in experimental group and elevated by 1.13±1.11'c in control group. (t=-3.1471, p=.0026) Thus, in this study there was a statistically significant difference in the change in the vital signs between the experimental group treated with music therapy and the control group which received no treatment. Because music therapy is valuable to decrease the anxiety of patients facing operations, the result of this study support its effect in relieving anxiety as a valuable nursing intervention. From this study, the following recommendations can be made : First, it is necessary to further study music therapy to develope a better system and determine optimal time. Second, it is necessary that more detailed re-search on measurement of changes in vital signs be done to determine changes over time intervals.

The purpose of this study was to demonstrate the effect of music therapy as a nursing intervention on changes in recovery of consciousness and vital signs for postoperative patients in the recovery room. The subject for this study were fifty three of postoperative patients who were transferred from the OR to the RR at Kwangju Christian Hospital in Kwangju City. Thirty of them were assigned to the experimental group, and twenty three, to the control group. The age of the subject was between twenty and sixty years of age. The subject had a general anesthesia without any special complications, and they were not completely awake. The data were collected for six months from July 1999 to February 2000. The method used was to compare the condition of the subjects in each group at the beginning and at certain times repeatedly. The features observed were the level of consciousness, the frequency of complaints of pain, and vital signs of the subject before and 15 minutes, 30 minutes, and 60 minutes after hearing their favorite music for 30 minutes. The results are as follows 1. The recovery of consciousness was revealed through significant changes in facial expression, facial color, and grip strength in the experimental group more strongly than in the control group. No significant changes were shown in verbal order. The differences in recovery of consciousness in the pre-post music therapy between the two groups was not significant in verbal order, facial expression, or grip strength. However, significant changes were seen in facial color. 2. There were no significant differences between the two groups in changes in the frequency of pain complaints after music therapy. However, a significant difference was shown in the pre-post music therapy scres. 3. Vital signs did not show a significant difference between the two groups. However, the $SPO_2$ of the experimental group was significantly elevated after 60 minutes. The difference pre-post to the music therapy in the vital signs between two groups was significant only in body temperature. This study showed that the effect of music therapy given to postoperative patients is that it promotes changes in facial expression, facial color, and grip strength helping recovery of consciousness, stabilizing vital signs, elevating levels of $SPO_2$. and reducing complaints of pain. It is recommended that if the patient wants it music therapy be given right after surgery in the recovery room as a nursing intervention.

Recently, owing to global warming, average summer temperatures are increasing and the number of hot days is increasing is increasing, which leads to an increase in heat stroke. In particular, outdoor workers directly exposed to the heat are at higher risk of heat stroke; therefore, preventing heat-related illnesses and managing safety have become important. Although various wearable devices have been developed to prevent heat stroke for outdoor workers, applying various sensors to the safety helmets that workers must wear is an excellent alternative. In this study, we developed a smart helmet that measures various vital signs of the wearer such as body temperature, heart rate, and sweat rate; external environmental signals such as temperature and humidity; and movement signals of the wearer such as roll and pitch angles. The smart helmet can acquire the various data by connecting with a smartphone application. Environmental data can check the status of heat wave advisory, and the individual vital signs can monitor the health of workers. In addition, we developed an algorithm that classifies the risk of heat-related illness as normal and abnormal by inputting a set of vital signs of the wearer using a support vector machine technique, which is a machine learning technique that allows for rapid binary classification with high reliability. Furthermore, the classified results suggest that the safety manager can supervise the prevention of heat stroke by receiving feedback from the control system.
