Objectives: The aim of the study was to investigate the potential of Yangdorak diagnosis application against gallstone scanned by Ultrasound diagnosis. Method: For this aim, among 97 patients who had visited Julip Korean Medicine Clinic from July 2016 to June 2023, 30 patients with no gallstone as a control group and 67 patients with gallstone and diagnosed by ultrasonography, were subjected to Yangdorak diagnosis. Then, the changes in Gallbladder Meridian (GB) value as F5 AVE(average of left and right GB value) by Yangdorak were comparatively analyzed between gallstone and non-gallstone groups and statistical significance was evaluated by Tukey's multiple comparison test using Prism software. Results: After all subjects were evaluated by the Yangdorak and ultrasonography to assess the potential of the Yangdorak diagnosis for gallstone, it was noteworthy that the Yangdorak values relevant to F5 AVE of female gallstone group(N=36) were significantly (p<0.001) decreased compared to the control group (N=30), while there was no significance in male gallstone group(N=31). Also, it was recognized significant difference between male and female groups. Conclusion: Based on these results, if the Yangdorak value can be estimated from a decrease with clinical symptom in female patient, it is recommended to follow up the ultrasonography test for diagnosing the gallstone.

Objectives : The aim of this study was to investigate the different of yangdorak diagnosis between low back pain patients and medical checkup group. Methods : We analyzed the measurement value of yangdorak on 103 patients with low back pain and 103 medical checkup persons in Korean males from March 1st, 2007 to September 30th, 2008 by using yangdorak(MEDIRA, Neomyth Co., Korea). Results : 1. In comparing results on the yangdorak general mean, low back pain group is statistically significant in comparison with medical checkup group(p<0.001). 2. In comparing results on each meridian yangdorak value, they were statistically significant between two groups(p<0.001). 3. In comparing result on the distance of yangdorak value from the mean, they were statistically significant between two groups at the Bladder-meridian(p<0.05), but not at the Kidney-meridian. Conclusions : This results suggest that yangdorak may be used for a method to objective clinical examination. But further studies are required for a use of practical indicator.

Objectives : Functional dyspepsia (FD) is one of the most common gastrointestinal diseases. Nevertheless, there are many unknown mechanisms of autonomic functioning in FD patients. This study was designed to investigate the relationship between FD and biosignals from heart rate variability (HRV) and Yangdorak diagnosis. Methods : 32 patients (22 female, 10 male; mean age 40) and 32 healthy volunteers (21 female, 11 malemean; age 38) participated in this study. First gastrointestinal symptoms rating scale (GSRS) was assessed by questionnaires in both groups to evaluate the types of gastrointestinal symptoms. Second, HRV and Yangdorak diagnosis were measured in both groups. Results : 1. The FD group in this study mainly had the complaint of 'bloating' symptoms. 2. There was statistically no significant difference between Yangdorak (total average and 24 acupoints) and HRV values except logarithmic low-frequency band (lnLF) and total power (TP) in frequency domain. 3. There was statistically no significant relationship between HRV and Yangdorak in either group. However, most Yangdorak values were positively related with some HRV values (low-frequency, low-frequency/high-frequency ratio and high-frequency, etc) in the control group. Conclusions : FD patients had relatively lesser sympathetic domain than healthy subjects, indicated by decreased lnLF and TP. Particularly, there were positive relationships and significant differences between Yangdorak and HRV in young healthy subjects. This suggests that biosignals from HRV may be a useful method that can differentiate FD from healthy state in those of young age.

In this paper, the Maekjin and the Yangdorak Diagnosis algorithm by using a neuro-fuzzy method is proposed and it is implemented on the DSP-based system. Maekjin is measured by 3-channels of the Maekjin board through Maekjin probe which is attached on Chon, Kwan and Chuk of patient's wrist. First, we experiment Chon, Kwan and Chuk, 3-parts simultaneously and second perform one part of Chon, Kwan and Chuk respectively, The experimental results show that the Maekjin signal is measured precisely with any Maekjin probe. In Yangdorak diagnosis, the pulse generated by electric stimulator stimulates a portion of body and the response signal is measured through electrodes which is attached on representative points of 12 kyungmaks. The experimental methods are (1) 1 channel-measure, (2) 2 channels-measure, (3) 6 channels-measure and (4) 24 channels-measure. A fuzzy diagnosis is performed and neural networks is learned using fuzzy values as inputs, and we show that neuro-fuzzy diagnosis method is performed well.

Objectives : Secondary amenorrhoea is the absence of menses for three months in a woman with previously normal menstruation or nine months for women with a history of oligomenorrhoea. It can be caused by stress, extreme weight loss, and excessive exercise. The purpose of this study was to report the clinical effects of herbal medicine on secondary amenorrhoea.Methods : We employed oriental medical treatments; herbal - medication (Hyunburikyungtang gamibang), acupuncture and moxibustion. We treated the patients one or two times a month with oriental therapy method. They took medicine three times a day after a meal. During taking medicine, we let the patients avoid fatty food, flour based food and alcohol. We evaluated the status of the patient, on the basis of the state of menstration and F2 level of Yangdorak. Because we diagnosed the condition of patients with the pattern of liver depression and qi stagnation, so F2 level of Yangdorak was an important point of the diagnosis. Yangdorak machine was Tormeter Iw - zen at Towatech Co.,Ltd.Results : After taking treatment - several times acupuncture and moxibustion during some period and taking herbal-medicine, they had menstrain naturally without taking any hormone drug. Also the amount of menstration has gradually increased. The F2 level of Yangdorak returned to normal range. The feeling of cold on hands, feet and lower abdomen was much improved.Conclusions : Herbal medicine (Hyunburikyungtang gamibang) with oriental medical treatments, acupuncture and moxibustion was effective in the treatment of secondary amenorrhoea.

Objectives: This study was aimed to develop a guideline for the application of diagnostic devices for menopausal syndrome. Methods: We conducted a literature review and a questionnaire survey on diagnostic devices including Digital Infrared Thermal Imaging (DITI), pulse diagnosis device, Heart Rate Variability (HRV), body composition analyzer, Yangdorak. Results: We retrieved some clinical values for usage of devices from the articles. Especially, DITI was useful to identify the pattern of body temperature distribution. The respondents answered that they diagnosed menopausal syndrome by using body composition analyzer (62.3%), DITI (60%), HRV (60%), pulse diagnosis device (45.7%), Yangdorak (34.3%). The respondents answered that they don't use diagnostic devices when they diagnosed menopausal syndrome because of absence of device, cost, difficulty of interpretation, substitution of another diagnostic method. After experts survey, it was recommended to use DITI, HRV, body composition analyzer. There was no consensus on the use of pulse diagnosis device, Yangdorak in diagnosing menopausal syndrome. Conclusions: We developed a guideline for the application of diagnostic devices for menopausal syndrome.

In this paper, with the reference of the pulse wave acquired by the pulse-checking device, it is measured the impedance on the key measuring points of the 12 kyungmaks of the human body's left and right by using 24-channels Yangdorak machine. Then, based on the Fuzzy theory, this study diagnosed the each meridian's strength and weakness. After that, both the strengthening and weakening stimulus of magnetic fields are applied to the dominant direction to find out how the degree of strength and weakness of the meridian changed. Ultimately, the magnetic therapy that can stimulate the magnetic field at the time of diagnosis and thereby balancing the interactive of five-system(O-hang) have been materialized. For the stimulation of magnetic fields, a stimulating device which can change the direction and time on a specific part of the key measuring points of the limbs of 24 kyungmaks have been developed and used. The therapeutic methods are as follows. First, the strength and weakness of the meridian have been determined. Second, both the extremely weak meridian of Yin(Shade) and Yang(Shine), and the extremely strong meridian of Yin and Yang were adjusted by applying appropriate ascending and descending stimuli respectively. All these adjusting processes can now be carried out automatically on a personal computer(PC).
