This study is a convergence study that empirically verifies the principles of the Hunminjeongeum Joongsung-Ja (中聲字, vowel) system, especially the principles of the pictorial patterns of the initial and re-involved characters, using magnetic resonance imaging (MRI). According to the principle stated in the Jejahae (制字解) of the Hunminjeongeum Haeryebon—that “the 28 characters of Jeongeum were each modeled after their shapes”—this study aimed to prove that all characters were devised to reflect the shape of the vocal tract when pronounced. Four participants, including both younger and older adults including both sexes were enrolled in this study, and real-time MRI scans and acoustic analysis were conducted. In the analysis of the Cho-Chul-Ja (初出字, /ㅗ, ㅏ, ㅜ, ㅓ/), clear differences were observed in the structure of the vocal tract and the shape of the resonance cavity according to the vowels, and the degree of lip opening and the length of the vocal tract showed a close relationship with the acoustic characteristics of each vowel. In the Jae-Chul-Ja (再出字, /ㅛ, ㅑ, ㅠ, ㅕ/), changes in the shape of the resonance cavity were observed along with changes in tongue movement and lip opening during diphthong utterances, and it was confirmed that this is directly related to acoustic characteristics. The results of this study confirmed that the principle of the Hunminjeongeum Joongsung-Ja (中聲字, vowel) is closely related to the form of resonance cavity in the actual articulation process. It was confirmed that it was created by the synthesis (Hapsung, 合成) of the three letters “Cheon-ji-in (天地人, /•, ㅡ, ㅣ/)”, and it was also confirmed that the pictorial principles of the first and second versions are based on the shape and movement of the resonance tube. It is significant in that it re-examines the scientific sophistication of the vowel system devised during the creation of Hunminjeongeum in the 15th century with modern technology. This shows that Hunminjeongeum is not just a philosophical symbol, but a writing system that reflects the anatomical structure and physiological movements of actual speech organs.

This paper briefly introduces the characteristics of the SAA method and its clinical research. The SHA-AM Acupuncture (SAA) method was developed by Sheyan Daoren, who published a book titled by Tips of acupuncture by Sheyan Daoren. Based on the traditional theory of yin and yang, five elements, visceral, qi and blood, and meridians, the SAA method further developed the principles of acupuncture reinforcing and reducing methods from Huang Di Nei Jing and Nan Jing. And it has further developed it's own unique theoretical system, which has been widely applied in Korea.

Cynomolgus monkeys as nonhuman primates are valuable animal models because they have a high level of human gene homology. There are many reference values for hematology and biochemistry of Cynomolgus monkeys that are needed for proper clinical diagnosis and biomedical research conduct. The body weight information and blood type are also key success factors in allogeneic or xenogeneic models. Moreover, the biological parameters could be different according to the origin of the Cynomolgus monkey. However, there are limited references provided, especially of Cambodia origin. In this study, we measured average body weight of 2,518 Cynomolgus monkeys and analyzed hematology and serum biochemistry using 119 males, and determined blood types in 642 monkeys with Cambodia origin. The average body weight of male Cynomolgus monkeys were 2.56±0.345 kg and female group was 2.43±0.330 kg at the age from 2 to 3 years. The male group showed relatively sharp increased average body weight from the 3 to 4 age period compared to the female group. In hematology and biochemistry, it was found that most of the data was similar when compared to other references even though some results showed differences. The ABO blood type result showed that type A, B, AB, and O was approximately 15.6, 33.3, 44.2, and 6.9%, respectively. The main blood type in this facility was B and AB. These biological background references of Cambodia origin could be used to provide important information to researchers who are using them in their biomedical research.

BACKGROUND: We developed a patient-centered, smartphone-based, diabetes care system (PSDCS). This study aims to test the feasibility of glycosylated hemoglobin (HbA1c) reduction with the PSDCS. METHODS: This study was a single-arm pilot study. The participants with type 2 diabetes mellitus were instructed to use the PSDCS, which integrates a Bluetooth-connected glucometer, digital food diary, and wearable physical activity monitoring device. The primary end point was the change in HbA1c from baseline after a 12-week intervention. RESULTS: Twenty-nine patients aged 53.9±9.1 years completed the study. HbA1c and fasting plasma glucose levels decreased significantly from baseline (7.7%±0.7% to 7.1%±0.6%, P<0.0001; 140.9±39.1 to 120.1±31.0 mg/dL, P=0.0088, respectively). The frequency of glucose monitoring correlated with the magnitude of HbA1c reduction (r=-0.57, P=0.0013). The components of the diabetes self-care activities, including diet, exercise, and glucose monitoring, were significantly improved, particularly in the upper tertile of HbA1c reduction. There were no severe adverse events during the intervention. CONCLUSION: A 12-week application of the PSDCS to patients with inadequately controlled type 2 diabetes resulted in a significant HbA1c reduction with tolerable safety profiles; these findings require confirmation in a future randomized controlled trial.
