The aim of this study was to determine whether or not cardiovascular reactivity parameters serve as good indicators in identifying differential emotion in children. The study particularly focused on five emotions(i.e., happiness, sadness, anger, stress, and boredom), thus, study participants were introduced to a combination of music, color, stories, and dolls to induce complex emotions. During the experiment, corresponding cardiovascular reactivity in response to the conditioned stimuli were recorded on physiological parameters including HR, RSA, HRV, HF HRV, LF HRV, and FPV. After the cardiovascular reactivity responses were measured, participants rated on the types and intensity of emotions they had experienced during the emotional stimuli exposure. Results on psychological response show that four emotions except for stress were appropriately and effectively induced participants by emotional stimuli. Findings of physiological responses suggest that, except for RSA, all of the physiological indicators show significant differences among five emotions. This indicates that children' emotions can be measured and differentiated by cardiovascular reactivity, or in other words, emotion specific responses have the ability to distinguish different emotions in children.

Objectives : The purpose of this study was to report the clinical characteristics of glossodynia patients and effects of traditional Korean treatment on glossodynia and to gather data in order to carry out future study. Methods : We surveyed 40 glossodynia patients visiting the Department of Korean Internal Medicine of Stroke and Neurological Disorders Center, Kyung Hee University Hospital at Gangdong and analyzed their glossodynia questionnaires, examination results, and progression of symptoms. Results : In Glossodynia patients the average age was 62.4 years old. Glossodynia was more prevalent in females than males (5.67:1). Red tongue color, white fur, and fissured tongue were observed most often. The average glossodynia duration was 36.1 months and the average glossodynia degree was VAS 5.6. The most commonly appearing symptom was burning sense, and dryness of tongue. In Korean medicine diagnosis, Yin, deficiency, Tae-eum was most commonly diagnosed. In herbal medicine, Gamichungsim-tang was the most frequently prescribed. In laboratory tests, zinc deficiency was the most common result. In heart rate variability (HRV), average SDNN was 34.03 and average LF/HF ratio was 2.11. Of 40 patients, 23 completed treatment and their pain was relieved from average VAS 5.52 to VAS 3.63. Pre-and post-treatment results showed a significant difference. The average duration of treatment was 34.91 days. Conclusions : The results of this study suggest that Korean medical approach and treatment for glossodynia could be effective. Further study should be conducted for more valuable information.

Objective: The objective of this study was to investigate the effect of 20-day litter weight on behavior and heart rate variability (HRV) of piglets under stress. Methods: Forty four original litters were categorized as high litter weight (HW) litters (n = 22) and low litter weight (LW) litters (n = 22) by 20-day litter weight. From each original HW litter, three males and three females were randomly selected after weaning and the 12 piglets from two original litters with similar age of days were regrouped into one new high litter weight (NHW) litter (11 NHW litters in total). The original LW litters were treated with a same program, so that there were 11 new low litter weight (NLW) litters as well. The latencies to first fighting, fighting frequencies and duration within three hours were recorded after regrouping and the lesions on body surface within 48 hours were scored. Besides, HR (heart rate, bpm, beats per minute) and activity count (ACT), time domain indexes and frequency domain indexes of the piglets were measured in an isolation trial to analyze the discrepancy in coping with stress between the original HW and LW litters. Results: The results exhibited that piglets from the HW litters launched fighting sooner and got statistically higher skin lesion score than those from the LW litters (p = 0.03 and 0.02, respectively). Regarding the HRV detection, compared with the HW litters, the LW litters exhibited a lower mean HR (p<0.05). In the isolation test, a highly significant higher ACT value was observed between the HW litters, compared to the LW litters (p<0.01). Significant differences were observed in standard deviation of R-R intervals, standard deviation of all normal to normal intervals, and most frequency-domain indicators: very low-frequency, low-frequency, and high frequency between the HW and LW litters as well. The difference in LF:HF was not significant (p = 0.779). Conclusion: This study suggests that compared with litters of low 20-day litter weights, litters with higher 20-day litter weight take more positive strategies to cope with stress and have stronger HRV regulation capacity; HW litters demonstrate better anti-stress and adaptation capacity in the case of regrouping and isolation.

Objectives : The objective of this study is to compare the circadian patterns of heart rate variability assessed by 24-hour ambulatory electrocardiographic (ECG) recordings during day shift and night shift among the workers in the 5 days-concecutive-12-hour shift in an automobile factory in Korea. Methods : The study population consisted 300 workers, who were randomly selected among the 8700 total workers in one car factory. To analyse circadian variation, the 24-hour ECG recordings (Marquette) were measured during day shift (08:00-20:00 h) and night shift (20:00-08:00 h). Analysis was performed for all time and frequency domain measures of HRV. 233 workers completed taking 24-hour ECG recordings. Results : This study shows that the 24 hourcircadian variation mainly follows work/sleep cycle rather than day/night cycle among shift workers. This study also shows that among the night shift, the circadian variation between work and sleep cycle decreased compared to the work/sleep cycle among day shift workers. All time and frequency domain parameters (except LF/HF ratio) show significantly different between work and sleep in the day shift and night shift. Conclusion : These changes in heart rate variability circadian rhythms reflect significant reductions in cardiac parasympathetic activity with the most marked reduction in normal vagal activity among the shift workers. Especially, it suggests the circadian rhytm has blunted among the night workers. The quantification of the circadian variation in HRV can be a surrogates of workers' potential health risk, as well as suggests possible mechanisms through which the shift works compromise workers' health.

Objectives : This study was conducted to assess the effect of Uhwangchungsimwon on the autonomic nervous system. Methods : Eligible subjects were enrolled from healthy people in their 20s-30s. They were divided into two groups, the UC group (n=22) and the control group (n=20). We monitored ECG from 14:00 to 18:00 in both groups. In the UC group, subjects were administered UC at 15:00. HRV analysis was conducted at 14:00, 16:00, and 17:00 for 512 seconds. Results : The degree of LF/HF ratio change was significantly higher in the UC group at 1 hour after administration. Conclusion : We suggest Uhwangchungsimwon may be useful for stabilization of the autonomic nervous system by activating parasympathetic nerve in healthy people.

Background : Recently a discussion about Qi including a study about the effect or the theory of acupuncture is getting prevailing in various angles. In most of studies about acupuncture stimulus, 'Filiform acupuncture'(毫鍼) is used. A study about Nine kinds of acupuncture(九鍼), except 'Filiform acupuncture'(毫鍼) has not been reported yet, and there is no study about using a special acupuncture made for controling Qi either. Objectives : 'DONG CHU CHIM' can be used for patients who are scared of a pain because it is a medical Qikong tool and non-invasive stimulus one. To assess a effect of Qikong operation using 'DONG CHU CHIM' objectively, we stimulated non-invasive to Sobu point of 30 normal adults using 'DONG CHU CHIM' and examined the result in the basis of high confirmed and repetitive HRV which is a functional assessment method of the autonomic nervous system. Method : This study has been proceeded in three periods. Total was 35min : 10min for the former and latter period of acupuncture stimulus, l5min for the acupuncture stimulus period. For each period, we measured 5min of 3 times(Stage I, II, III). Result : Comparing the changes of HRV during pre-stimulation and post-stimulation, HRT was significantly reduced, LOGTP, LOGVLF, LOGLF, LF/HF were significantly increased and SDNN, LOGHF were generally increased but did not show any significant changes. So we think that the stimulus of 'DONG CHU CHIM' affects on the sympathetic system and parasympathetic system, it activates the autonomic nervous system, and it makes the inequality of the sympathetic and parasympathetic nerve to be equal status. Conclusions : We can conclude that the non-invasive stimulus of 'DONG CHU CHIM' can affect significantly to the autonomic nervous system. So it can be used in clinic as a tool of Qikong operation, and it can be also used to weak patients or children because it doesn't give a lot of pain like 'Filiform acupuncture'(毫鍼) compared to invasive stimulus. By the basis of this study, more studies about the effect of 'DONG CHE CHIM' should be done in the future.

Objective : Using patterns of change in heart rate variability (HRV), we investigated the effects of stress exposure and type of anger expression on cardiovascular diseases. Methods : Eighty-nine medical students were evaluated by STAXI-K, BDI, BAI, and measured HRV. According to the scores of anger expression questions in STAXI-K, objects are comparted to three groups. Each group is compared with others on the levels of depression, anxiety and HRV. Additionally objects are divided into two groups of functional anger expression group and dysfunctional anger expression group, and each group also divided into two groups, depending on the exposure of stressful situation or not. Members who took part in the stress exposure groups, they've got a serial arithmetic process for five minutes. We surveyed patterns of HRV in 4 each groups and estimated interactions between existence of stressful situation or type of anger expression and HRV. Results : Irrespective of stress manipulation, the dysfunctional anger expression group showed a marked increase in the LF/HF ratio in comparison to the functional anger expression group. Also, under conditions of stress manipulation, the stress exposure group exhibited a relatively increased level of TP. It can't be discriminated any correlations between stress manipulation and type of anger expression. Conclusion : Both of them, exposure to the stressful situation and type of anger expression, have influence on cardiovascular diseases. By controlling anger and way of express that, it is possible to diminish the incidence of cardiovascular diseases.

Objectives: The aim of this study was to investigate the usefulness of a comprehensive diagnosis of yin-deficiency and heart rate variability in halitosis patients. Methods: We surveyed 62 halitosis patients visiting the Halitosis Clinic in the Kyung Hee University Oriental Medicine Hospital from August 2010 to April 2011. The subjects were evaluated on self-assessed severity of halitosis and xerostomia using visual analogue scale (VAS) score and yin-deficiency condition (based on the 10-item Yin-deficiency Questionnaire). Salivary function was measured by the unstimulated salivary flow rate (USFR) and heart rate variability (HRV) parameters were recorded by SA-2000E (Medicore Co. Ltd., Korea). Results: There were substantial significant positive correlations between halitosis, xerostomia VAS scores and yin-deficiency scores. There was significant negative correlation between xerostomia VAS score and USFR. Compared to the normal USFR group (USFR>0.1$m{\ell}$/min), the decreased USFR group (USFR${\leq}0.1m{\ell}$/min) showed significant lower values of Total Power (TP), Lower Frequency (LF), and High frequency (HF). Conclusions: The results of this study suggest that the comprehensive diagnosis of yin-deficiency and HRV are useful in diagnosing of halitosis patients with xerostomia. Therefore, we assume that improvement of yin-deficiency condition can be a potentially effective way to treat halitosis with xerostomia.

향에 의해 유발되는 감성에 대한 중추신경계 및 자율신경계의 반응의 변화를 측정하기 위해 안정시키는 향과 각성시키는 향을 사용하여 주관적 평가와 동시에 시행하였다. 안정시키는 향으로 1% Lavendar 향을 사용하였고, 각성시키는 향으로 0.8% Jasmin 향을 사용하였으며, 안정상태를 향자극 전후에 측정하여 대조군으로 사용하였다. 중추신경계의 지표로 뇌파측정을 하였고 뇌파의 전극은 international 10-20 system에서 4 채널을 사용하였으며, 자율신경계의 지표로는 심전도, heart rate, 피부저항, 피부온도를 기록하였다. 뇌파의 분석은 Fast Fourier Transform analysis의 power spectra로 하였고, 그 frequency bands는 theta(4-8Hz), alpha(8-l3Hz), beta(14-30Hz)로 하였다 또한 심전도를 이용하여 심전도 상의 연속적인 R-R peak간 시간간격을 시계열 데이터로 재구성한 Heart rate variability 분석도 하였다. HRV 분석을 보다 정확히 할 수 있도록 호흡이 심전도에 미치는 영향을 제거하기 위하여 호흡을 분당 20회로 일정하게 하였다 생체신호 측정과 동시에 실시한 주관적 검사에서 lavendar 향은 친숙하게, jasmin 향은 활기차고 상쾌하고 유쾌하게 평가되었다. 뇌파 분석에서 lavendar 향을 주었을 때 theta의 증가 양상을 보였으며, Jasmin 향을 주었을 때는 모든 채널에서 beta 파의 증가 양상을 보였다. 또한 HRV 분석 결과 부교삼신경의 활동성이 부각되는 HF/LF의 값이 lavendar에서는 대조 자극보다 높게 나타났으며, jasmin에서는 대조자극보다 낮은 값이 나타나는 경향을 보였다. 결론적으로 안정과 각성의 후각 자극으로 인한 감성의 변화를 뇌파와 자율신경계 등의 생체지표로 관찰할 수 있었다.정하는 감성요인의 차이를 알 수 있었으며 또한 essential oil에서는 성별 차이가 없는데 반해 페르몬 향의 경우 성별의 차이를 나타내었다.. 방법을 타액과 혈청내 testosterone 농도 측정에 응용하여 RIA의 결과와 비교하여 본 바 상관관계가 타액에서 r=0.969, 혈청에서 r=0.990으로 두 결과가 잘 일치하였다. 본 실험에서 측정된 한국인 여성의 타액내 testosterone농도는 107.7$\pm$12.0 pmol／l이었고, 남성의 타액내 농도는 274.2$\pm$22.1 pmol／l이었다. 이상의 결과로 보아 본 연구에서 정립된 EIA 방법은 RIA를 대신하여 소규모의 실험실에서도 활용할 수 있을 것으로 사려된다.또한 상실기 이후 배아에서 합성되며, 발생시기에 따라 그 영향이 다르고 팽창과 부화에 관여하는 것으로 사료된다. 더욱이, 조선의 ${\ulcorner}$구성교육${\lrcorner}$이 조선총독부의 관리하에서 실행되었다는 것을, 당시의 사범학교를 중심으로 한 교육조직을 기술한 문헌에 의해 규명시켰다.nd of letter design which represents -natural objects and was popular at the time of Yukjo Dynasty, and there are some documents of that period left both in Japan and Korea.

Objectives : We investigated the effects of distilled Rehmannia glutinosa Herbal Acupuncture on autonomic nervous system with the Heart Rate Variability(HRV) in adult man. as well as we tried to observe how distilled Rehmannia glutinosa Herbal Acupuncture on the balance of the autonomic nervous system. Methods : We investigated on 58 healthy volunteers consisted of 28 subjects in experiment(distilled Rehmannia glutinosa Herbal Acupuncture) group and 30 subjects in control(Normal Saline) group. Study form was a randomized, placebo-controlled, double-blind clinical trial. 28 subjects in experiment group were injected distilled Rehmannia glutinosa Herbal Acupuncture at $GB_{21}$(Kyonjong) and 30 subjects in control group were injected Normal Saline at $G_{21}$(Kyonjong). except of 2 subjects(in control group) who can't be measured and 6 subjects(2 in experiment group and 4 in control group) who move or make unforceable error during measuring. Finally 26 subject in experiment group and 24 subject in control group are studied. We measured HRV by PolyG-I on 7 times : before and after injection per 5 minutes during 30 minutes. The SPSS 10.0 for windows was used to analyze the data and the paired t-test(in group) and Student t-test(between two groups) were used to verify the result. Results : 1. After distilled Rehmannia glutinosa Herbal Acupuncture injection, Mean HRV is significantly low only for first 5 minute, SDNN is significantly high after 5 minute, Complexity is significantly low only from 20 minute to 25 minute. HRV index is significantly high for first 5minute and from 10 minute to after 10 minute. 2. HRV index of distilled Rehmannia glutinosa Herbal Acupuncture Group significantly increased from 25 minute to 30 minute, and pNN50 of Rehmannia glutinosa Herbal Acupuncture Group significantly decreased from 20 minute to 30 minute compared with those of Normal Saline group. 3. After distilled Rehmannia glutinosa Herbal Acupuncture injection, Ln(TP) and Ln(VLF) are significantly high after injection. Normalized LF is significantly high from 5 minute to 20 minute and from 25 minute and 30 minute. Normalized HF is significantly low from 5minute to 20 minute and from 25 minute and 30 minute. 4. Ln(TP) and Ln(VLF) of distilled Rehmannia glutinosa Herbal Acupuncture Group significantly increased from 20 minute to 25 minute compared with those of Normal Saline group. Conclusions : The results suggest that Rehmannia glutinosa Herbal Acupuncture in healthy adult man tend to activate the autonomic nervous system and parasympathetic nervous system compared to Normal Saline within normal range.
