Objectives : The purpose of this study is to assess the effect of Taegeuk acupuncture on reducing mental stress by analyzing heart rate variability in Soeumin. Methods : Six Soeumin-diagnosed men participated in this study. They were randomly divided into group A and group B. Each participant went through 4 sessions every week with 1 week of washout period in between each session. HRV was measured three times at every session; at baseline, after administering mentally stressful circumstances and after applying Soeumin Taegeuk acupuncture or Soyangin Taegeuk acupuncture. This study was designed as a crossover clinical trial. Group A participants were treated with two sets of Soeumin Taegeuk and Soyangin Taegeuk acupuncture treatment in respective order (i.e. Soeumin Taegeuk - Soyangin Taegeuk - Soeumin Taegeuk - Soyangin Taegeuk acupuncture treatment). Group B participants were treated with reverse-ordered acupuncture treatment (i.e. Soyangin Taegeuk - Soeumin Taegeuk - Soyangin Taegeuk - Soeumin Taegeuk acupuncture treatment ). Bayesian analysis was performed by using WinBUGS(Ver. 1.4.3) for comparison between Soeumin Taegeuk acupuncture and Soyangin Taegeuk acupuncture. Results : Overall, Soeumin Taegeuk acupuncture tends to reduce LF/HF ratio, LF, HF, LF(Norm) and increase HF(Norm) more than Soyangin Taegeuk acupuncture, but the difference was not statistically significant. In one participant, however, Soeumin Taegeuk acupuncture reduced LF/HF ratio, LF(Norm) and increased HF(Norm) more than Soyangin Taegeuk acupuncture, and the difference was stastatistically significant. Conclusions : This study suggests that Soeumin Taegeuk acupuncture might be an effective means of stabilizing mental stress-induced imbalance of autonomic nervous system for Soeumin.

Objectives: The aim of the study was to investigate the characteristics of the autonomic innervation of the heart in Precocious Puberty (PP) Girls.Methods: We studied 87 girls visiting Dongshin University Suncheon Oriental Medicine hospital from first Januarty 2013 to 31th December 2015. Among the 87 girls who were selected 14 people under the age of 8. The subjects were categorized in two groups, 2 PP girls and 12 healthy controls. We studied the difference of Heart rate variability (HRV) between two groups by Independent samples T-test using SPSS for windows (version 22.0).Results: The Standard deviation of all normal R-R intervals (SDNN), The spuare root of the sum of the spuare of difference between adjacent normal R-R intervals (RMS-SD) of PP group was non-significantly lower than non-PP group. Total power (TP), Very low frequency power (VLF), High frequency power (HF), Low frequency power (LF) of PP group was non-significantly lower than non-PP group, LF/HF ratio of PP group was significantly higher than non-PP group. Normalized high frequency power (HF norm) of PP group was non-significantly lower than non-PP group. Normalized low frequency power (LF norm) of PP was non-signficantly higher than non-PP group.Conclusion: The results suggest that imbalance of sympathetic and parasympathetic nervous system from girls of precocious puberty can be seen.

Purpose: The purpose of this study was to examine the effects of aroma-necklace application on perceived stress, symptoms of stress and changes in autonomic nervous system among nursing students in clinical training. Methods: A research design for this study was a non-equivalent control group, non-synchronized pre-post test. The experimental group (n=39) underwent aroma inhalation by necklace which contains an essential oil mixture of lavender and sweet orange mixture in ratio of 2:1 for 2 weeks while the control group (n=36) received placebo therapy. The data were collected using self-administered questionnaires and measurement of heart rate variability (HRV) and analyzed using the PASW 18.0 program. Results: The perceived stress scores and scores of peripheral manifestations in the experimental group were significantly lower than those of the control group. All indices of HRV were significantly different between the two groups. LF norm and LF/HF ratio in the experimental group were significantly lower than those of the control group, and HF norm in the experimental group was significantly higher than that in the control group. Conclusion: It can be suggested that aroma-necklace application was effective in decreasing perceived stress and peripheral manifestations of stress and in changing HRV indices among nursing students in clinical training.

Purpose: The aim of the study was to compare the characteristics of the autonomic innervation of the heart in polycystic ovary syndrome(PCOS) patients with regulary cycling controls. Methods: We studied 21 patients visiting $\bigcirc\bigcirc$hospital from 25th June 2009 to 25th June 2010. The subjects were categorized in two groups, 11 PCOS patients and 10 healthy regularly cycling controls. We studied the difference of Heart rate variability (HRV) between two groups by Independent samples T-test using SPSS for windows(version 17.0). Results: The Standard deviation of all normal R-R intervals (SDNN), The spuare root of the sum of the spuare of difference between adjacent normal R-R intervals (RMS-SD) of PCOS group was non-significantly lower than non-PCOS group. High frequency power (HF) and Normalized high frequency power (HF norm) of PCOS group was significantly higher than non-PCOS group. Normalized low frequency power (LF norm) of PCOS was signficantly lower than non-PCOS group. The results means increased sympathetic and decreased vagal modulation. Total power (TP), Very low frequency power (VLF) of PCOS group was non-significantly lower than non-PCOS group. Low frequency power (LF), LF/HF ratio of PCOS group was non-significantly higher than non-PCOS group. Conclusion: The results suggest that PCOS can be related to decreased activity of parasympathetic nervous system.

Objective : The purpose of this experimental-controlled study was to investigate the characteristics of the autonomic nervous system in students with Keongke by using HRV(Heart rate variability) and PSV(Pupil size variability). Method : The study group was consisted of 11 students with self recognition as the experimental group, and 25 normal students as the control group. Informations on gender and age were obtained by medical charts and personal interviews. By using heart rate variability and pupil size variability, we measured the value of HRT(Heart rate), SDNN(Standard deviation of NN intervals), LFnorm(Low frequency normalization), HFnorm(High frequency normalization), LF/HF ratio, Pupil area, B.S.(Basic size), C.R.(Max Constriction Rate) and 1s.d.(1sec Dilation Rate). I compared the degrees of the sympathetic and parasympathetic activity. Result : 1. In the result of heart rate variability between experimental and control group, none of the parameters of experimental group were significantly different from control group. And even though there were no statistical significance, there were some numerical differences in SDNN, LF norm, HF norm. 2. In pupil size variability, C.R. and 1s.d. of the experimental group were increased compared to control group. Conclusion : The study results suggest that the group with Keongke has differences of autonomic nervous system as compared to those in normal state. Measurement value of PSV is a new technical approach to estimate the autonomic nervous system.

Objective : To determine the relationships between customer's attitude, the subjective norm and the intention to use hospital-based health promotion services. Methods : This study was based on the theory of reasoned action, suggested by Fishbein and Ajzen. The subjects of this study were 501 residents of Seoul, Bun-dang, Il-san and Pyung-chon city, under 65 years, who were stratified by sex and age. A covariance structural analysis was used to identify the structural relationships between attitude towards health promotion programs or services, their subjective norm and their intention to use the aforementioned services. Results : The subjective norm for using the health promotion programs or services provided by hospitals was a significant predictor of the intention to use, but the attitude towards the services was not significant Conclusions : Our results suggest that a customer's reference group affects their use of the hospital-based health promotion services. Because the subjects of this study were restricted to specific urban areas, there are limitations to generalizing the study results. Despite the limitations of these results, they can serve as baseline information for the understanding of consumers behavior toward hospital-based health promotion services.

Mobile Entertainment is the new era in mobile communication. Mobile Entertainment service is a combination of games, music, videos, chatting and telecommunication which has created a wide market in India. There is a variation between male and female customers towards Mobile Entertainment services. This study is aimed at analyzing gender impact of attitude, subjective norm, perceived behaviour control intention and behaviour towards mobile entertainment services. The Theory of planned Behaviour (TPB) provided a framework. Total 566 male and 376 female mobile users of different age groups participated in the research. The data analysis was conducted in three-stages. First, reliability tests were performed. Upon satisfactory results, confirmatory factor analysis (CFA) is used to analysis convergent, concurrent and discriminant validity of the model. Once the model was validated Structural Equation Model (SEM) Multi-group analysis is used to find the impact of gender behaviour towards Mobile entertainment services. The results of the study confirmed that the model is viable in predicting variation in gender impact on mobile entertainment services. The findings have revealed that attitude, perceived behaviour control and intention has a significant impact on behaviour to use mobile entertainment but subjective norm has no significant impact on behaviour to use mobile entertainment.

Purpose: The purpose of this study was to identify effects of attitude, subjective norm, and perceived behavior control toward Human Papillomavirus (HPV) on HPV vaccination intention in female high school students. Methods: Subjects of this study were female students aged 16 to 17 years, the optimal age group of HPV vaccination, arbitrarily selected from three high schools in B city. A total of 140 students agreed to participate in this study. Data were analyzed using descriptive statistics, t-test, ANOVA, correlation, and stepwise multiple regression. Results: Attitude, subjective norm, and perceived behavior control toward HPV were factors influencing HPV vaccination intention of subjects. Perceived behavior control toward HPV vaccination was the most influential factor. These factors accounted for 49% of HPV vaccination intention. Conclusion: These results suggest a need to increase perceived behavior control to increase HPV vaccination intention. The government needs to establish a national policy system such as financial support for HPV vaccines and free vaccinations so that students are aware that HPV vaccines can be easily inoculated.

Purpose: Oligomenorrhea is clinically important because it can be progressed to amenorrhea. The purpose of this study is to analyse Autonomic Nerve Function of some oligomenorrheic patients by using HRV(Heart Rate Variability). Methods: We studied 35 patients visiting OO Oriental Hospital from 1st November 2006 to 31th May 2007. One woman who takes antidepressant is excluded. 17 oligomenorrheic group and 17 normal menstrual cycle group were compared with HRV. The SPSS 12.0 for windows was used to analyze the data and Mann Whitney U-test were used to verify the results. Results: Mean PR, LF norm, LF/HF ratio of oligimenorrheic group are higher than normal menstrual cycle group. But there is no statistically significance. SDNN, RMS-SD, ln TP, ln VLF, ln LF, ln HF, HF norm of oligimenorrheic group are lower than normal menstrual cycle group. But there is no statistically significance. Conclusion: It can be suggested that oligomenorrhea can be related to increased activities of sympathetic nerve and decreased activities of general autonomic nerve function. But, we need study with more subjects for settling this.
