Background: This study evaluated pulp vitality of anterior permanent teeth using pulse oximetry (PO), which is already used for monitoring of patient's $SpO_2$ and pulse rates (PR). Also we compared with ice tests and electric pulp test (EPT). Methods: 9 teeth, endodontic treated, were selected as non-vital teeth group. 17 vital teeth were selected as control group. Our aim is to compare sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of ice test, electric pulp test and pulse oximetry, respectively. Pulse oximetry has two test results, $SpO_2$ and pulse rates. Also we calculated correlation and statistical significances by Pearson's test between EPT and pulse oximetry. Results: Sensitivity, specificity, PPV, NPV were calculated on each tests. Ice test has results of 1.00, 0.89, 0.94 and 1.00, respectively. EPT has results of 0.94, 0.78, 0.89 and 0.88 respectively. $SpO_2$ has results of 0.94, 1.00, 1.00 and 0.90, respectively. PR has results of all 1.00. Conclusions: PO showed relatively accurate, stable and objective results on both $SpO_2$ and PR. Percentage of ability of accurate diagnosis for vital teeth is 94% for ice test, 89% for EPT, 100% for $SpO_2$ and PR. Percentage of ability of accurate diagnosis for non-vital teeth is 100% for ice test, 88% for EPT, 90% for $SpO_2$ and 100% for PR. In additions, PR could be more accurate and significant tests than $SpO_2$.

Purpose: Music intervention has long been used in research of patients undergoing surgical operation in reducing anxiety level and improve surgical outcome. However, there are few studies that have considered a patient's music preference. We investigated the effect of the tailored music intervention which chose music according to the patient's preference on anxiety level and vital signs. Method: The subjects were 50 patients who received regional anesthesia for surgical operation at D hospital in Pohang city from April, 2006 to November, 2006. All of the subjects were randomly assigned either music group (30 subjects) or non-music group (20 subjects). As the patients arrived in the operating room, vital signs were monitored until the subjects were transferred to the recovery room, while Spielberger's STAI-KYZ questionnaires were applied twice to measure preoperative and intra-operative anxiety. The data were analyzed by 2-test, t-test, one-way ANCOVA and repeated measures ANOVA using SPSS 12.0/PC+. Results: There were no significant differences between the two groups on vital signs. All of the vital signs increased when the subjects arrived in the operating room, but decreased quickly once the operation began, regardless of the groups. However, the music group reported significantly less intra-operative anxiety, compared to the non-music group (F=15.208, p<.000), when preoperative anxiety was treated as a covariance. Conclusion: The findings support that the use of music which was chosen by patients during the surgery significantly reduced patient's intra-operative anxiety during regional anesthesia.

This study examined the effects of favorite music therapy on the anxiety and vital signs at each point in gynecologic surgery using the general anesthesia. The research design was a non-equivalent control group non-synchronized design. The data were collected from May 1 to July 30, 2013 and the participants were 44 patients (experimental group, 21, control group, 23) received music therapy while waiting for anesthetic induction and PACU (Post Anesthesia Care Unit). Repeated measures ANOVA was performed to analyze the data by SPSS 18.0. Music therapy reduced the anxiety level at inducing the anesthetic time, and awakening time (p=.003; p=.011). The systolic blood pressure maintained stability at discharge from the PACU (p=.023), and pulse rate was stable at the awakening time (p=.016). This findings support the use of music as a nursing intervention to reduce anxiety and maintain the vital signs for gynecologic surgery patients under general anesthesia.

The purpose of this study was to evaluate the accuracy of an electronic apex locator, the Neosono - M, in determining the location of the cementodentinal junction. A total of 26 teeth with 46 canals were evaluated. The apex locator was used to locate the file and the teeth extracted. The specimen were prepared with highspeed burs and sandpaper discs to a thickness of $250{\sim}300{\mu}m$. Distances were measured from the cementodentinal junction with the use of polarizing microscope. Measurements made by the apex locator were also compared with those by the X - ray. The results were as follows. 1. The apex locator and X - ray were to measure a mean value of 0.17, 0.45mm coronal to the CDJ respectively. There was no significant difference between the accuracy of the apex locator and that of X - ray. 2. There was no significant difference between the accuracy of apex locator in vital and in nonvital teeth, and between in narrow and in wide canals. 3. The files in nonvital and narrow group were apical to the CDJ significantly than those of vital and narrow, vital and wide, and non vital and wide groups.

Objectives: This study aimed to systematically review the pain and flare-up effects of calcium hydroxide (CH) as intracanal medication (ICM) in non-vital mature teeth. Materials and Methods: Electronic-databases searching for published and grey literature and manual searching were conducted. Only randomized clinical trials (RCTs) were included comparing CH to other ICMs in non-vital mature teeth. The risk of bias was assessed using the RoB 2.0 Cochrane tool. The main outcomes were pain and flare-up. Qualitative and quantitative analysis, wherever applicable, was performed. The certainty of evidence (CoE) was assessed using Grading of Recommendations Assessment, Development and Evaluation (GRADE). Results: Sixteen articles were included in 6 comparisons at different time points for different outcomes. CH reduced pain risk than no ICM within the 1-14-days interval (p < 0.05) and than triple-antibiotic paste within the first day (p < 0.05) and was similar to corticosteroid/antibiotics combination (p > 0.05). Chlorhexidine (CHX) or CH/CHX, however, reduced pain levels than CH alone (p < 0.05). CH showed higher flare-up risk than CHX (p < 0.05). CoE, however, ranged from very low to moderate. Conclusion: Most comparisons for different outcomes are based on very few studies, mostly low-powered, with an overall low CoE. Thus, the available evidence is considered insufficient to either support or refute CH effectiveness or to recommend one ICM over another. Therefore, further well-designed, larger RCTs are required.

PURPOSE: To prevent secondary complications from decreased pulmonary functions and promote neurological recovery, identification of respiratory capacity change patterns depending on different postures of stroke patients and investigation of their properties are needed for active rehabilitation. Therefore, this study was conducted to investigate the changes in vital capacity in response to different positions and to implement the results as clinical data. METHODS: A respiratory function test was administered to 52 patients with stroke in the sitting, supine, paretic side lying, and non-paretic side lying positions. Pulmonary function indexes used for comparison were forced vital capacity (FVC), forced expiratory volume at 1 second (FEV1), forced expiratory flow 25-75% (FEF 25-75%), and maximum voluntary ventilation (MVV). One-way repeated ANOVA was used for analysis, and post hoc analysis was conducted using least significant difference (LSD). RESULTS: All pulmonary function indexes were measured in the order of sitting, paretic side lying, supine, and non-paretic side lying positions. Excluding the FEF25-75% and MVV of the supine compared with the paretic side lying position, all other pulmonary function indexes differed significantly (p<.05). CONCLUSION: There are differences in pulmonary function indexes depending on different postures of stroke patients, and the study showed that the non-paretic side lying position yielded the greatest effect on lung ventilation mechanisms. Based on these results, appropriate postures need to be considered during physical therapy interventions for stroke patients.

Recently, as the uncontact service is activated in earnest due to the Corona 19 virus, the necessity of system development to provide non-face-to-face contact remote medical service has increased. In this study, we propose a smart healthcare system, Rm_She(Remote Medical Smart Healthcare System). Rm_She can collect and manage various vital signs information by connecting various healthcare products that detect bio-signals based on IoT to one application. The health check app (HC_app) is used to connect vital sign measurement devices to a wireless LAN and receive vital sign values from the HC_app. Then, the vital signs are output to the user on the smartphone, and the corresponding information is transmitted to the healthcare management server. The healthcare server receives the measured values and stores them in a database, and the stored measured values are provided as a web service so that medical staff can remotely monitor them in real time.

It is well known that vital statistics is of great importance as basic data for establishing various range of national policies. Especially, vital statistics is important among demographic information for monitoring and evaluating the population policy, for constructing life table, for making population projection, and for studying various aspects of the society. In principle, the production of vital statistics is based on the registration system. It is, however, still observed that there are some limitations in utilizing fully the registration system due to the inherent problems such as problems in its coverage, accuracies and timeliness. Thus, as an alternative, many countries conduct survey on vital statistics in order to supplement the registration system and obtain in-depth data. Korea is no exception in this aspect. The National Bureau of Statistics carries out the so-called Continuous Demographic Survey. This is a kind of multi-round retrospective survey, covering 32, 000 households and having reference period of one month. The survey has also characteristics of multi-subject sample. Thus, surveys on economic activity status of population, house-hold income & expenditure, and social indicators are together conducted with the same sample. It is, however, found that the survey itself tends to have some quality problems. Especially, the quality problems connected with field data collection are summarized as coverage error, non-response error and response error. Although it is inevitable not to be free from these errors, we should make all our efforts to reduce the errors. The probable schemes pointed out in this paper are as follows : 1) the strengthening formal quality control activities, 2) the review of the survey method, i. e., the combining interview method with mail-sending and mail-back method or pick-up method, 3) well documentation for various cases found in every stage of data collection, and 4) the strengthening the analytical activities. It is, also, emphasized that sincerity of planners and interviewers is the most important factor among other things.

The main purpose of this study was to examine the validity of the vital sign as an instrument of stress reaction measurement. From July to August 1986, stress reaction was evaluated by the difference of endoscopic vital sign on 93 G-I troubled out-patients who underwent endoscopy for the first time and did not have any evidence of cardiovascular disease. The data were analysed by x$^2$-test, Paired . t-test, ANCOVA and Multiple Comparison Test. The result of study were as follows: 1. The frequency of gastric disease was differed by the family type, and the mobility of gastritis and gastric cancer were more increased in nuclear family than in large family (p=0.019). 2. In a comparison of before with after 5 minutes endoscopic vital sign, and a Pulse rate (P=0.0001), respiration rate (p=0.0001), systolic blood pressure (p=0.0002) and diastolic blood Pressure (P=0.006) were significantly increased after 5minutes by endoscopy in contrast with before 5minutes. 3. The control of before 5 minutes of endoscopic vital sign, after 5 minutes of endoscopic systolic (p=0.024) and diastolic blood pressure (p=0.0146) were more elevated in biopsyed group than in non-biopsyed, group. And after 5minutes of endoscopic respiration rate was more increased in gastric cancer than in gastritis (p=0.0406) or gastric ulcer (p=0.0073). And after 5 minutes of endoscopic systolic blood pressure was elevated over 50years old men (P=0.0238). In short, the increase of a pulse rate af ter 5 minutes of endoscopy was not influenced by general characteristics of samples in this experiment. And systolic blood pressure over 50years old men must be considered of physiological hypertension.
