A 42-year-old male patient with prolonged throat pain and discomfort, dry mouth, and general weakness and recently diagnosed with tonsillitis, pulmonary embolism, and venous thrombosis was admitted to the internal Korean medicine department. A sudden onset of diabetic ketoacidosis with hyperammonemia was diagnosed on the second day of treatment. During admission, the patient received insulin therapy, hydration, and traditional Korean medicine treatment, including herbal medicine. Subjective symptom change was evaluated daily and blood glucose level checked five times per day. At discharge, the patient's fasting and postprandial blood sugar levels were adequate. After an additional two weeks of herbal treatment, the symptoms were significantly ameliorated. Thus, having been admitted with dysregulated glucose metabolism leading to a hyperglycemic crisis after a series of inflammatory events, the patient showed symptomatic improvements and decreased blood glucose after 18 days of hospitalization and treatment.

Coronavirus disease 2019 (COVID-19) cases surged across South Korea during the omicron-variant wave. We aimed to report the effectiveness of herbal medicine administered through telemedicine consultations as an adjunctive therapy for COVID-19. Patients with confirmed COVID-19 who were self-isolating at home were provided telephone consultations through a Korean Medicine clinic between January and March 2022. On the basis of their dominant symptoms, the patients were prescribed Eunkyo-san for seven days. Patients were asked to evaluate the severity of their COVID-19 symptoms before and after treatment by numeric rating scale. Of ten patients, more than half of them reported cough, fever, headache, and sore throat on the first telephone consultation. Patients reported that all symptoms related to COVID-19 disappeared completely on the second consultation. No severe adverse events were identified. The results of this case series suggest that Eunkyo-san administration can be a beneficial adjunctive therapy for patients with COVID-19.

There are three sorts of voices of female vocalists: soprano, mezzo-soprano, and contralto according to the transliteration. Among them, the soprano has the highest vocal range. Since the voice is generated through the human vocal tract based on the voice generation model, it is greatly influenced by the vocal tract. The structure of vocal organs differs from person to person, and the formants characteristic of vocalization differ accordingly. The formant characteristic refers to a characteristic in which a specific frequency band appears distinctly due to resonance occurring in each vocal tract in the vocal process. Formant characteristics include personality that occurs in the throat, jaw, lips, and teeth, as well as phonological properties of phonemes. The first formant is the throat, the second formant is the jaw, the third formant and the fourth formant are caused by the resonance phenomenon in the lips and the teeth. Among them, pronunciation is influenced not only by phonological information but also by jaws, lips and teeth. When the mouth is small or the jaw is stiff when pronouncing, pronunciation becomes unclear. Therefore, the higher the accuracy of the pronunciation characteristics, the more clearly the formant characteristics appear in the grammar spectrum. However, many soprano singers can not open their mouths because their jaws, lips, teeth, and facial muscles are rigid to maintain high tones when singing, which makes the pronunciation unclear and thus the formant characteristics become unclear. In this paper, in order to confirm the accuracy of the pronunciation characteristics of soprano singers, the experimental group was selected as the soprano singers A, B, C, D, E of Korea and analyzed the grammar spectrum and conducted the MOS test for pronunciation recognition. As a result, soprano singer B showed a clear recognition from F1 to F5 and MOS test result showed the highest recognition rate with 4.6 points. Soprano singers A, C, and D appear from F1 to F3, but it was difficult to find formants above 2kHz. Finally, the soprano singer E had difficulty in finding the formant as a whole, and MOS test showed the lowest recognition rate at 2.1 points. Therefore, we confirmed that the soprano singer B, which exhibits the most distinct formant characteristics in the grammar spectrum, has the best pronunciation accuracy.

Questionnaires were given to the 240 teachers and the number of collected questionnaire is 112. The result of the questionnaire analysis is like the following. First, the answered teachers aged 35~39, 36.6%; experience 6~10 years 37.5%; the number of class 31~40, 28.6%. Among the answered of the school doctors is practicioners. The doctors major subjects are 26.8% of internal medicine and 35.7% of surgery. Second, in elementary & secondary school nurse teachers received in-service training for the primary health assessment. And then 37.5% of schools practiced the health assessment. The term of the health assessment is largely a-year-length, occurately its rate of schools have practiced the assessment reaches 81.0%. The number of health assessment are consist of eyes, nose, ear, throat, skin, spine, heart and other abnormal regions and diseases all over the body. And 83.3% of the rate of the health assessment includes all these contents. The period of the health assessment is 7 to 28 days. Third, the physical examination conducted by school doctors is 91.0%. The method is various; one is 56.6% of the students who checked first by he nurse teacher. The number of 15.1% of the schools is directly checked by the school doctor. The invited medical doctors are divided into two categories. The number of general physician is 61.9%. Contrary to that school doctors are 38.1%. The contents of the medical examination is all the items printed on the medical examination sheet. To follow the medical examination sheet the number of school is 59.6%. Eyes, throat, skin and heart etc. partly medical examination is 40.4%. The rate of schools that used only stethoscope, tongue pressor as the medical instruments reaches 53.4% and 87.1% of elementary & secondary school give the invited doctors the allowance a nurse teachers conference decided. The number of 8.9% schools pay the doctors independent allowance. The medical examomatopm allowance is 200 to 250 won per capita. The rate is 56.1%. Forth, after the medical examination 72.1% of school sends letter to the parents to notice the result of the examination. The number of response from parent is 12.5%. The observation record in secondary school is 70.6% for junior, and 80.0% for senior respectively, and 65.5% is for the elementary school children.

Formaldehyde가 주성분인 접착제를 사용하는 목재 가공업소에서 특히 접착부서에 48개월 이상 근무했던 3명의 여자근로자들이 눈, 비강, 구강, 인후 및 피부의 자극증상과 호흡곤란등의 증상을 호소하였다. 이에 목재 가공업소 전 근로자 26명을 대상으로 설문지를 통하여 자각증상 여부를 확인하고 흉부 X-선 촬영, 폐기능 검사, 심전도, 동맥혈 포화도 검사 및 혈색소 검사등을 실시한 결과는 다음과 같다. 1. 접착부서 근무자중 장기 노출자인 환자군과 단기 노출자인 비환자군과 비교시에 냄새를 잘 못 맡으며 입안에 물집이 생기고 혀가 갈라지고 맛을 잘 모르며 목이 쉬는 증상에서 통계적으로 유의한 차이를 보였다 (p<0.05). 2. 접착부서 근무자중 환자군과 전체 비폭로군과 비교시에는 냄새를 잘 못 맡고 입안에 물집이 생기며 혀가 갈라지고 맛을 잘 모르며 목이 잘 쉬고 인후통이 오며 가슴이 답답하고, 피부 자극증상과 정신이 멍해진다는 증상에서 통계적으로 유의하게 나타났다 (p<0.05). 3. 환자군과 비폭로군의 여자군과만 비교한 경우에는 냄새를 잘 못 맡고, 혀가 갈라지며, 맛을 잘 모르고 목이 쉬며 인후통이 있고 피부자극 증상과 정신이 멍해진다는 증상에서 유의하게 나타났다(p<0.05). 4. 폐기능 검사의 결과는 환자군에서 노력성 폐활량(FVC)과 일초량 ($FEV_1$)의 감소를 보였다(P>0.05). 5. 전 근로자들에게서 흉부X-선 촬영, 심전도, 동맥혈 포화도 검사등에 큰 변화를 보이지 않았으며, 전체적으로 빈혈 양상을 보였으나 폭로 여부에 따른 차이는 없었다. 접착 부서 근로자들이 증상을 호소해서부터 임시검진과 작업장 환경 측정을 실시하고 정밀검사를 완료하기까지의 과정이 신속히 이루어지지 못했던 것은 폭로 작업장 근로자들의 문제점을 더욱 정확히 파악하고 건강을 보호 관리한다는 측면에서 개선되어야 할 것이다. 이와 같이 연구 수행에 많은 제한점이 있었으나 접착제를 사용하는 목재 가공업소에서는 복합적인 유해물질에 영향을 받을 수 있는데, 특히 formaldehyde 폭로에 인한 눈, 비강, 구강, 인후와 피부의 자극증상과 호흡곤란 및 폐기능의 저하가 문제시 되므로 폭로 여부를 결정할 수 있는 특별한 생물학적 감시 방법이 없어 증상에 의존하여 중독 여부를 파악하는데에는 어려움이 있으나 폭로 근로자들의 건강을 지키기 위해서는 작업장 환경측정등을 통한 폭로 감시를 더욱 철저히 하여야겠다. 또한 최근에 들어와서는 formaldehyde가 발암물질이라는 논쟁이 끊임없이 되고있으므로 폭로 근로자들에 대한 예방대책과 이에 따른 폭넓은 연구가 이루어져야 할 것이다.

Background: Antibiotic resistance has been becoming serious challenge to human beings. Overuse of antibiotics, especially, for infants is concerned, but studies are very few for the prescribing pattern of antibiotic use for infants. This study analyzes prescribing patterns of antibiotics in outpatients of preschool children with acute respiratory tract infections in South Korea. Methods: Data are used from 2011 Health Insurance Review & Assessment Services-pediatric patients sample. Inclusion criteria is outpatient children (0 to 5 years) with top five frequent diseases. Prescription rates are analyzed by types of disease, provider, specialty, region, and ages. Binary or multinomial logit models are used to analyze determinants of providers' prescription pattern. Results: The main findings are as follows. First, distributions of prescription rates are shown as L-shape or M-shape depending on the types of disease. Second, the prescription variation is so large among providers, where providers are polarized as a group with low prescription rates and the other group with high prescription rates, though the shapes are shown diversified across types of disease. Third, prescription rates appear to be lower in pediatrics and higher in ENT (ear-nose-throat). Fourth, broad spectrum antibiotics are widely used among children. Finally, the logit analysis shows similar results with descriptive statistics, but partly different results across types of disease. Conclusion: Antibiotics for respiratory tract infections of infants are used excessively with a large variation among providers, and especially broad spectrum antibiotics are used. The prescription guideline for antibiotics should be provided for each specific disease to reduce antibiotic resistance in the future.

Allergic rhinitis is a common disease of childhood characterized by nasal, throat, and ocular itching, rhinorrhea, sneezing, nasal congestion. Those affected with allergic rhinitis often suffer from associated inflammatory conditions of the mucosa, such as allergic conjunctivitis, rhinosinusitis, asthma, otitis media with effusion, and other atopic conditions, such as eczema and food allergies. Allergic rhinitis must be diagnosed and treated properly to prevent complications and impaired quality of life. Despite a high prevalence, allergic rhinitis isoften undiagnosed and inadequately treated, especially in the pediatric population. The first step in treatment is environmental control when appropriate. It may be difficult to eliminate all offending allergens effectively to reduce symptoms, so medications are often required. Many different classes of medications are now available, and they have been shown to be effective and safe in a large number of well-designed, clinical trials. Antihistamines are effective in treating immediate symptoms of sneezing, pruritus, watery eyes, and rhinorrhea. Second generation antihistamines are the preferred antihistamines because of their superior side effect profile. Thus, decongestants are commonly used with oral antihistamines. Intranasal corticosteroids are the most effective therapy for allergic rhinitis. Leukotriene modifier may be as effective as antihistamines in treating allergic rhinitis symptoms. Cromolyn sodium is an option for mild disease when used prophylactically, and ipratropium bromide is effective when rhinorrhea is the predominant symptom. When avoidance measures and medications are not effective, specific immunotherapy is an effective alternative. Only immunotherapy results in sustained changes in the immune system. Because of improved understanding of the pathogenesis, new and better therapies may be forthcoming. The effective treatment of allergic rhinitis in children will reduce symptoms and will improve overall health and quality of life, making a happier, healthier child.

초음속 이젝터 유동특성은 압축성, 비정상성, 충격파 둥으로 인하여 충분히 알려져 있지 않다. 종래의 이론적/실험적 연구결과들은 대부분 1차원 가정 하에서 얻어진 것들이며, 현재까지 수치계산법을 이용하여 이젝터 내부 유동장을 해석한 실례가 많지 않다. 뿐만 아니라 기존의 수치계산 결과들은 2차유동의 질량유량이 매우 작거나 없는 단순한 유동장에 대한 것들이었다. 본 연구에서는 초음속 이젝터-펌프 유동장을 수치적으로 해석하기 위하여 축대칭 수치계산 모델을 이용하였다. 수치계산은 축대칭 압축성 Navier-Stokes 방정식에 유한체적법을 적용하였으며, 표준형 $\kappa$ -$\varepsilon$ 난류모델을 이용하였고, 2차유동의 질량유량을 변화시켜 1차유동과 2차유동의 질량비의 변화에 따른 이젝터 내부 유동장의 변화를 조사하였다. 그 결과, 2차목을 가지지 않는 일정 단면적의 혼합부를 가지는 이젝터의 경우, 이젝터 내부의 유동장 특성은 2차유동의 질량유량의 변화와 거의 무관하게 나타났다. 그러나 2차목을 가지는 경우는 2차유동의 질량유량의 증가에 따른 노즐출구 주위에서 배압으로 인하여 이젝터 내부 유동장이 크게 변화하였다.

Objective: The main purpose of this work was to investigate the effect of berberine hydrochloride (BH) on the proliferation, apoptosis, migration, and invasion of CNE-1 nasopharyngeal carcinoma cells. Our results shed light on the functional components of traditional Chinese herbs for potential use in modern medicine. Methods: The CNE-1 cell line was treated with different concentrations of BH and effects on cell viability and proliferation were evaluated using the Cell Counting Kit-8 (CCK-8) assay. Anti-migratory and anti-invasive actions of BH were investigated using wound healing assays and the Millicell Hanging cell culture insert system, respectively. Expression of the epithelial-mesenchymal transition (EMT)-related gene twist (Twist) was analyzed by real-time PCR and Western blotting. Apoptosis was estimated with an annexin-V fluorescein (FITC) apoptosis detection kit, as well as with reference to levels of activated caspase-3 of CNE-1 cells before and after treatment with BH utilizing fluorescence spectroscopy. Results: BH was capable of reducing proliferation and viability of CNE-1 cells in a dose- and time-dependent manner, also demonstrating anti-migratory and anti-invasive capacities which correlated with reduction in expression of Twist. Finally, BH was able to induce significant amounts of apoptosis in CNE-1 cells, as demonstrated by an increase in the activity of caspase-3 and in annexin-V staining following treatment. Conclusion: BH extracted from rhizoma coptidis demonstrated an ability to block proliferation, induce apoptosis, and impair the migration and invasion of the CNE-1 cell line Considering these properties, our results suggest that BH could be an important compound for consideration in the treatment of nasopharyngeal carcinoma.
