Recently commercial mixed-reality devices have be launched and a variety of mixed-reality content has produced, but narrow field of view, which appear to be hardware technical limitations, are mentioned as an important issue for hindering immersion and limiting the scope of use. We propose a new innovative system that cooperate multiple beam projectors and a number of mixed reality devices. Using this technology, users can maximize immersion and minimize frustration of narrow viewing angles through 3D object rendering on background of large 2D screens. This system, named BtS (Beyond the Sight), is implemented on a client-server basis and includes the ability to calibrate between devices, share spatial coordinate systems, and synchronize real-time renderings as core modules. In this paper, each configuration module is described in detail and the possibility of its performance and application is shown through the introduction of mixed reality content case created using BtS system.

Objectives: The purpose of this study is to understand the experience of traffic accident patients with serious injury treated with Traditional Korean Medicine (TKM). Methods: This study was conducted on the basis of grounded theory. We recruited 10 participants who had been hospitalized in Dongguk University Bundang Oriental Hospital after traffic accident. Raw data was collected by in-depth interview, and analyzed by using constant comparison. The coding(open-axial-selective) was performed in order to create paradigm and theoretical model, which can explain main theme of this study. Results: Core phenomenon of this study was 'Experiencing TKM treatment as an alternative' and core category was 'Searching for the answer to the management of traffic accident sequela through TKM treatment' Conclusions: For patients with serious injury, 'Experiencing TKM treatment as an alternative' has meaning as the following: First, The absence of accurate radiography and surgical management makes it hard for patients to choose Korean medicine hospital immediately after traffic accident. Second, Effectiveness of TKM treatment should be evaluated in the long term. Third, TKM treatment is superior to Western medicine treatment in managing long-term patients who suffered from serious injury involved in traffic accident. Finally, Cooperative service of the Western medicine and TKM will provide more satisfactory medical care for traffic accident patients.

The survival time of breast cancer patients with lung metastasis has been prolonged as treatment methods have improved. However, there is yet no definitive therapy for the additional symptoms of lung metastasis to improve the quality of life of these patients. We report a patient who was suffering from pleural effusion due to metastasized breast cancer. She was treated with Korean medicine, including herbal medicine (Bojungikgi-tang-gami), combined with hormone therapy, for two months. We assessed her other symptoms, such as shortness of breath, generalized weakness, and lower extremity swelling, using a numeric rating scale (NRS). We also evaluated pleural effusion with chest X-rays. Shortness of breath was maintained at NRS 5, generalized weakness was slightly improved from NRS 6~7 to NRS 7~8 (10=healthy condition), and lower extremity edema was improved from NRS 3 to NRS 2 (10=highest score of discomfort). Malignant pleural effusion was maintained during the admission period. This report suggests that Korean medicine can help to maintain malignant pleural effusion and improve additional symptoms of lung metastasis.

Intractable hiccups are those which persist for more than one month and can often occur in patients with disorders of the central nervous system, such as stroke, epilepsy, or brain tumor. An 80-year-old male patient undergoing conservative hemodialysis for diabetic nephropathy, recently developed paralysis and dysphagia due to central nervous system complications including stroke and epilepsy. He was admitted to the ◯◯ Oriental Medicine Hospital, and treated with herbal medicine (Gyulpijugyeo-tang, Jeonssiigong-san, and Ijin-tang) and electrical acupuncture for 30 days. No side effects were observed during hospitalization. The frequency and duration of hiccups were measured daily and found to reduce, and the effect persisted during his admission. The patient took no other nervous system drugs. In conclusion, Korean medicine like gyulpijugyeo-tang and acupuncture can be effective for patients with intractable hiccups who cannot use alternative drugs or treatment, because of other complications.

Objectives: We investigated the effects of Clean-DM4 (C-DM4), a polyherbal extract consisting of Coptidis Rhizoma, Salviae Miltiorrhiza Radix, and Cinnamomi Cortex on high fat diet (HFD)-induced obesity and diabetes in mice. Methods: The C57BL/6 mice (6 weeks) were fed a HFD for 8 weeks and then administrated with C-DM4 extract at 500 mg/kg (p.o.) once daily for 4 weeks. The changes of body weights, calorie intakes, and fasting blood glucose (FBG) levels were measured in mice. The serum levels of glucose, insulin, total cholesterol, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were measured in mice by enzyme-based assay. It was also observed the histological changes of pancreas, liver, and fat tissues with hematoxylin and eosin (H&E) staining. Results: The increase of calorie intakes and FBG levels in HFD-induced obesity mice was significantly decreased by oral administration of C-DM4 extract. C-DM4 extract administration was significantly reduced the increased levels of glucose, insulin, total cholesterol, AST, and ALT in obesity mice. In addition, C-DM4 extract inhibited lipid droplet accumulation in liver tissues of obesity mice, hyperplasia of pancreatic islets, and enlargement of adipocytes in adipose tissues. Conclusions: Our study indicates that C-DM4 extract could help improve obesity and to prevent diabetes progression.

Objectives This study was conducted to characterize scoliosis patients visiting Korean medicine hospital and to analyze the demands and factors affecting discomfort. Methods This retrospective study analyzed 33 scoliosis patients who visited Korean medicine hospital from March, 2021 to October, 2021. The data analysis consisted of three factors: (1) demographic characteristics, (2) characteristics of demands on Korean medicine (reasons for choosing Korean medical treatment, preferred treatment methods, most uncomfortable part, treatment priorities) and (3) discomfort factors (treatment experiences, diagnosed age and Cobb's angle). Statistical analyses were performed and a p-value≤0.05 was considered to be statistically significant. Results 43.75% of the patients chose 'effectiveness' for the reason why they preferred Korean medicine treatment. 'Chuna treatment' was the most preferred treatment method. The patients chose 'lower back' for the most uncomfortable part and 'pain' for the highest priority of improvement. The Cobb's angle of included patients was 16.02±7.65° and it is not much differ to average of Cobb's angle in Korean. Discomfort was more severe in the patients with treatment-experienced than treatment-naive. The score of discomfort in appearance and psychological were higher in the patients diagnosed in childhood or adolescent period than who were diagnosed after adult. Classification based on Cobb's angle showed no statistical difference. Conclusions Not only Cobb's angle but also other clinical factors should be considered for effective treatment in scoliosis. Also, It is necessary to pay attention to adult scoliosis patients.
