Users may experience a sub-type of motion sickness, called cybersickness, when interacting with virtual reality (VR) applications in the state of wearing head mounted display (HMD) devices. Although the root cause of cybersickness is still unclear, it is believed to result from a sensory mismatch between visual and vestibular systems. However, there is a lack of studies developing data collection and analysis systems to measure cybersickness. In this paper, therefore, a system is designed that collects electroencephalography (EEG) and physiological data from a user wearing a VR HMD device through an internet of things (IoT) platform and decides whether a user experiences a symptom of cybersickness, namely dizziness, or not by using a decision threshold. Experimental results showed that the proposed system achieved about 92% accuracy of a dizziness detection when considering 14 participants.

In order to find out the relationship between the Eight Principle Pattern Identification of Yin-Yang, Exterior-Interior and the Sasang constitution, we analyzed the clinical data from 500 women with menstrual pain and women without menstrual pain. In the previous study, the subject's information of Typology Complexion Pulse and Symptom was collected, and Eight Principle Pattern Identification was executed based on this. Later, The relationship between the Sasang constitution and the Eight Principle Pattern Identification was statistically analyzed. The obvious difference between the experimental group and the control group in the patterns of Yin-Yang and Exterior-Interior is that patients who complain of menstrual pain do not maintain harmony with the yin-yang ratio, it can be said that the patterns of Yin-Yang and Exterior-Interior can be a identification standard that significantly obscures the condition of the disease. There was a significant difference between the Sasang constitution and the Eight Principle Pattern Identification of Yin-Yang. There was no significant difference between the Sasang constitution and the Eight Principle Pattern Identification of Exterior-Interior. It is assumed that the relationship between the Eight Principle Pattern Identification and the Sasang constitution has changed depending on the difference a view of emotional Qi and pathogenic Qi.

This study was conducted to find objective diagnostic indicators for the Eight Principle Pattern Identification using a pulse wave analyzer. Typology Complexion Pulse and Symptom data from 500 women over the age of 18 were used. Five experts made a diagnosis of Eight Principle Pattern Identification and divided the subjects into 'Yin-Yang', 'Exterior-Interior', 'Cold-Heat', 'Deficiency-Excess' groups. Their pulse waves were measured in the left and right radial arteries, and it was investigated whether there was a significant difference between groups in the pulse wave parameter values. 'Yin' group showed a significantly lower value in the left radial artery for Ener, Emin, EIX, T4T, T4TT parameters and in the Right for T2, T2T, T5. The Vmag, As and Ad parameters were significantly different between the 'Exterior' and 'Interior' groups. 'Heat' group showed a significantly higher value in the right radial artery for RAI/t parameter. 'Deficiency' group showed a significantly higher value in the right radial artery for W, Angl parameters. Through this study, significant pulse wave parameters were found, and they can be used as objective diagnostic indicators for Eight Principle Pattern Identification.

Crohn's disease (CD) is an idiopathic inflammatory bowel disease (IBD) with unknown etiopathogenesis. Currently there are no definitive treatment modalities for CD. This case report presents clinical remission and its maintenance of CD induced by Korean herbal medicine treatment. A 56-year-old male patient diagnosed as CD by capsule endoscopy presented to a Korean Medicine clinic with severe abdominal pain as a chief complaint. Despite taking 5-aminosalicylic acid and immunosuppressant for 2 years, his abdominal pain was worsening at the time of visit. Treatment was initiated with Jinmoo-tang based on pattern identification and continued for approximately a year with some modifications according to patient's symptom changes. He was mainly given Jinmoo-Tang for a year and clinical remission was achieved; he could stop taking western medications. For 6 years since then, he took Korean medicine from time to time when he felt his condition went down and he is still maintaining remission. There were no adverse events reported. This case report suggests that individualized Korean herbal medicine treatment may have the potential for induction and maintenance of clinical remission of CD. Further research is warranted to establish an evidence-base for such approach.

Purpose: The purpose of this study was to investigate factors related to the levels of health-related quality of life (HRQoL) in elderly women based on Wilson and Cleary's HRQoL model. Methods: This study analyzed data from the eighth Korea National Health and Nutrition Examination Survey 2019 on 868 women over the age of 65 years. Based on the HRQoL model, parameters were categorized as personal, environmental, and physiological characteristics; symptom status; functional status; and perception of health status. The data were analyzed by quantile regression. Results: The overall level of HRQoL was 0.87. Factors related to HRQoL in the 10% quantile were higher education level, higher economic status, economic activity, more walking days, fewer diseases, lower stress, less activity limitation, and higher perceived health status. Factors related to the 25% quantile of HRQoL were more walking days, fewer diseases, less activity limitation, and higher perceived health status. Factors related to the 50% quantile were age, economic activity, more walking days, fewer disease, lower stress, less activity limitation, and higher perceived health status. Factors related to the 75% quantile of HRQoL were smoking, more walking days, fewer diseases, lower stress, less activity limitation, and higher perceived health status. Conclusion: While differing parameters were identified according to the level of HRQoL of elderly women in Korea, there were five common factors. Interventions that focus on increasing walking, mitigating diseases, stress, and activity limitations, and improving perceived health status can improve HRQoL.

This study aims to report a case of facial dermatitis herpetiformis with allergy diseases improved by administration of Mahaengeuigam-tang (Maxingyigan-tang). Multiple blisters appeared on the patient's face, Erythema, papules, and scales were also observed on the neck, back, and knee areas of the patient. The patient has had cough, sputum, and dyspnea symptoms since she was 5-6 months old. After diagnosing the patient's condition as dermatitis herpetiformis, atopic dermatitis, and bronchial asthma through history taking and symptom observation, Mahaengeuigam-tang (Maxingyigan-tang) was prescribed for about 30 days. As a result of evaluation through our own criteria, dermatitis herpetiformis symptoms improved from 18 to 2 points. Atopic dermatitis and asthma symptoms also decreased from 12 to 0 and 20 to 3 points, respectively. Since this study has proven the efficacy of Mahaengeuigam-tang (Maxingyigan-tang) for dermatitis herpetiformis patient, this prescription may be fully utilized as the treatment for other inflammatory skin diseases.

Purpose: Odontomas represent a common clinical entity among odontogenic tumors, but are not well-addressed in the Vietnamese population. The present study aimed to determine the clinical and preclinical characteristics of odontomas and associated factors in the Vietnamese population. Materials and Methods: This retrospective study retrieved data from histopathological diagnoses from 2 central hospitals of Odonto-Stomatology in Ho Chi Minh City, Vietnam during 2004-2017. The odontomas were classified as complex (CxOD) or compound (CpOD) subtypes. The epidemiological, clinical, and radiological characteristics of the odontomas, stratified by subtype and sex, were obtained and analyzed. Results: Ninety cases, consisting of 46 CxODs and 44 CpODs, were included. The average age of patients was 32.4 (±20.2) years. The patients with CxOD were older than those with CpOD (P<0.05). Clinically, 67% of patients showed an intraoral bone expansion. Approximately 60% of patients with CxOD exhibited a painful symptom, about 3-fold more than those with CpOD (P<0.05), whereas almost all patients with CpOD exhibited perturbations of dentition, unlike those with CxOD (P<0.05). Radiologically, CxOD was characterized by a larger dimension than CpOD in both sexes (P<0.05), and CpOD induced complications in adjacent teeth more often than CxOD (P<0.05). The development of odontoma with advancing age differed significantly in odontoma subtypes related to their pathological origins, and between the sexes, resulting from different physiological states. Conclusion: The findings of this study highlight the value of clinical and radiological features of odontomas and their associated factors for the early diagnosis and adequate treatment of younger patients.

The purpose of this study is to report a clinical case of a patient with CIPN (Chemotherapy Induced Peripheral Neuropathy) successfully treated with Korean medicine interventions including acupuncture, herbal medicine and moxibustion. The patient is a female with CIPN who was diagnosed with ascending colon cancer and suffering from paresthesia of extremities after chemotherapy of platinum compounds. The patient was treated mainly with electroacupuncture (Ex-LE 10), indirect moxibustion and herbal medicine (Ucha-Shinki-hwan granule). The clinical outcomes were measured by NCI CTCAE grade, EORTC QLQ-C30 (CIPN20) scale and patient's assessment of symptoms. In this case, the NCI CTCAE grade was improved from II to I. The scores of global health status and functional scale in QLQ-C30 were increased and symptom scale was decreased. Especially, this case shows a noticeable decrease in sensory scale in QLQ-CIPN20. In patient's general assessment, the scale was changed from 10 to 5. Korean medical interventions including acupuncture, herbal medicine and moxibustion could potentially be an effective treatment for CIPN if further researches are conducted.

Uterus myoma is a benign tumor of smooth muscle in the wall of the uterus, In oriental medicine, we used to made an effort to management this patients without surgical operation. Doctors have treated patients of uterus myoma mainly by checking over each symptom they have. Then we think that patients have some symptoms in relation to an etiological cause. So I have carried out this study to investigate association of DSOM scores and an attack of uterus myoma in oriental medicine. We chose 3 groups, the first one is 257 uterus myoma patients who visited Dongeui University Oriental Medical Center from May 2001 to June 2006, the second one is 558 outpatients who didn't have uterus myoma from May 2005 to June 2005, the third one is 129 clinical trials who volunteered for Sasang constitutional medicine. Then we made up 3 groups to checkup DSOM, and investigated the All DSOM Fluents which effect uterus myoma patients using regression model. Logistic regression analysis indicate as follows ; In comparison with 558 outpatients data, blood stasis(血瘀), dryness(燥) is associated positively and insufficiency of Yang(陽虛), spleen(脾), phlegm(痰) negatively, and mean of the index for pathogenic factor(病機指標 平均) of deficiency of qi(氣虛), heart(心) negatively. In comparison with 129 clinical trials data, blood stasis(血瘀) is associated positively and phlegm(痰) negatively, and mean of the index for pathogenic factor(炳機指標 平均) of deficiency of Yin(陰虛), liver(肝), diarrhea positively, heart(心) negatively. 3. In investigation of DSOM items, items of blood stasis(血瘀), deficiency of Yin(陰虛), coldness(寒) is associated positively and items of heart(心), spleen(脾), Phlegm(痰) negatively.

${\ll}$Gup Yu Bang${\gg}$ is the first korean book that specialized in pediatrics. It was written by Jo Jeong-jun in 1869 and contains 87 medical records. Medical records is one of the best way to develop one’s abilities of curing a disease without clinical practice and understanding medical condition of the time. These days we are fully aware of the importance of medical records, but there is no sufficient paper or study on medical records. On this study, we investigate 87 medical record of ${\ll}$Gup Yu Bang${\gg}$ by statistical methods. It was analyzed on the base of items such as age, sex, disease, method of medical treatment, treating prescription, modified medicinal substance, progress of disease. ${\ll}$Gup Yu Bang${\gg}$ contain 87 medical records and among of them, 84 records were Jo Jeong-jun own writings of clinical case. Systemic division of disease showed the highest in digestive disease and most frequent case was symptom of vomiting and diarrhea. The distribution of age was showed the highest in the age group under 5 years and the number of male case was more than female case. It showed that he considered observation of the patient's expression in diagnosis methods and have used 87 kinds of treating prescription and the external treatment, acupuncture, moxa. It showed that he quoted a lot of treating prescription from ${\ll}$Dong eui bo gam${\gg}$, ${\ll}$Yi-Hak-Yip-Mun${\gg}$ and ${\ll}$Xiao Er Yao Zheang Zhi Jue${\gg}$. The further study on medical records in traditional medical literatures, would reveal the developmental progress of Korean pediatrics and inform more actual proof on medical condition of the time.
