Objectives: This study aimed to explore the impact of semi-occluded vocal tract exercises (SOVTE) with varied vibration sources and durations on the vocal performance of healthy adults. In addition, we sought to confirm the safety of voiced high-frequency oscillation (VHFO) intervention and provide basic data for performances in relation to straw phonation (SP). Methods: The study included 34 healthy adults with no vocal impairments, comprising 8 males and 26 females. The mean age of the participants was 23.00± 2.06 years. To assess vocal characteristics during VHFO and SP, voice samples were recorded at three specific time points: prior to performing SOVTE (M0), after 1 minute of exercise (M1), and after 3 minutes of exercise (M3). Cepstral, perturbation, electroglottographic analyses were conducted on the recorded samples of vowel and sentences. Psychometric evaluation was conducted using questionnaires to gauge the self-reported severity of voice and vocal fatigue. Results: No statistically significant differences were observed in the average number of performances or duration per phonation between the two methods. When compared to baseline, CPPV significantly increased after 1 minute and 3 minutes of performance and Acoustic Psychometric Severity Index of Dysphonia decreased after 3 minutes of performance in VHFO. Both methods exhibited no significant differences in terms of psychometric and electroglottographic measurements. Conclusion: Results objectively confirmed the safety of VHFO intervention. This study is clinically significant as it lays the groundwork for future development of optimal treatment regimens and therapeutic programs for voice disorder patients, using foundational data on VHFO.

조현아,Young Lee Jung,이용훈,이유창,Jung Eun Lee,이솔재,정수진,김종화 대한비만학회 2017 The Korean journal of obesity Vol.26 No.2

Background: Dapagliflozin, a sodium-glucose cotransporter-2 inhibitor, reduces hyperglycemia and body weight by inhibiting renal glucose reabsorption. However, only a few studies have demonstrated efficacy of dapagliflozin for type 2 diabetic patients in Korea. We evaluated the efficacy and safety of dapagliflozin for Korean type 2 diabetes patients. Methods: This is a retrospective study that included data from 61 patients who received 12 months of dapagliflozin therapy and who visited a single medical center between January 2015 and July 2016. Patients were separated into three groups: dual combination of dapagliflozin and metformin, triple combination of dapagliflozin and metformin with sulfonylurea, or dipeptidyl peptidase IV inhibitors, and quadriple combination of dapagliflozin, metformin, and sulfonylurea with dipeptidyl peptidase IV inhibitors. Patients who achieved ≥5% body weight reduction were classified as responders, and those who achieved <5% body weight reduction were classified as non-responders. Results: After 12 months, the mean change from baseline body weight was -3.4±2.6 kg (P<0.001) for all patients, -3.4±3.1 kg (P<0.001) for group 1, -2.7±2.0 kg (P=0.008) for group 2, and -4.0±2.3 kg (P<0.001) for group 3. Fasting C-peptide level was higher in the responder group than in the non-responder group (3.25±1.07 ng/mL vs. 2.62±1.02 ng/mL, P=0.023). In total, reductions in HbA1c, PP2, and FPG levels were -0.61±0.82% (P=0.000), -35.4±62 mg/dL (P=0.000), and -21.3±56.2 mg/dL (P=0.012), respectively. They had mild adverse events included orthostatic dizziness and urinary tract infection. Conclusion: SGLT2 inhibitor improved glycemic control and reduced body weight in a safe manner for patients with type 2 diabetes mellitus.

조현아 한국음악치료교육학회 2013 인간행동과 음악연구 Vol.10 No.2

The purpose of this study was to identify current trends in music therapy literature in Korea in order to provide the groundwork for future research. Therefore, 122 articles from the Korean Journal of Music Therapy (KJMT) from 1999 to 2012 and 76 articles from the Journal of Music and Human Behavior (JMHB, formerly known as Korean Journal of Music Therapy Education) from 2004 to 2012 were analyzed. Analysis was performed by identifying the frequency and percentage of the following items: type, population, topic, and methodology of published articles. In addition, the results obtained were compared and contrasted between these two publications. Overall, it was found that there was a high prevalence of descriptive studies (KJMT, 46%,; JMHB, 45%), applied research (KJMT, 51%; JMHB 66%), and quantitative studies (KJMT, 82%; JMHB 37%). In addition, ordinary people with no particular diagnosis were the most often studied population (34%). Differences were found in that a historical study was only found in KJMT whereas a philosophical study was published only in JMHB. Further analysis revealed that JMHB included a higher proportion of applied research than KJMT. In KJMT, quantitative research was appeared twice as often as qualitative and mixed-method research combined. On the other hand, a similar number of each of the three methodological types of studies appeared in JMHB. In conclusion, this study indicates that more effort should be made to increase the quantity and improve the quality of professional publications in the field of music therapy in Korea. 본 연구는 국내 음악치료 학술지 연구의 현황과 미래 방향성에 대한 기초 자료 제시를 목적으로 수행되었다. 이를 위해 1999년에서 2012년까지의 한국음악치료학회지(The Korean Journal of Music Therapy: KJMT) 122편과 2004년에서 2012년까지의 인간행동과 음악연구(Journal of Music and Human Behavior: JMHB. 전, 음악치료교육연구, Korean Journal of Music Therapy Education) 76편의 총 198편의 논문을 유형, 대상, 주제 및 방법에 따라 연도별 게재 현황과 비율을 고찰하고 각 영역별 비율에 대한 두 학술지의 공통점 및 차이점을 분석하였다. 분석 결과, 연구유형 중 기술연구가 46%(KJMT), 45%(JMHB)로 가장 큰 비중을 차지하였으며 연구대상에서는 두 학술지 모두 일반대상에 대한 연구가 큰 비중을 차지하였다(34%). 연구주제에서는 학문연구가 51%(KJMT), 66%(JMHB)로 가장 많이 나타났으며 연구방법에서는 양적 연구가 82%(KJMt), 37%(JMHB)를 보이며 각 영역에서 가장 높은 비율을 나타냈다. 차이점으로 KJMT에 게재된 연구유형에는 역사연구가 있었으나 철학연구는 없었던 반면, JMHB에는 철학연구는 있었으나 역사연구는 없었다. 연구주제에서는 KJMT보다 JMHB에서 학문연구의 비율이 높았으며 연구방법에서는 KJMT에서 양적 연구가 질적, 통합적 연구보다 2배 이상 높은 비율을 보였다. 반면, JMHB에서는 각 연구가 유사한 비율을 보였다. 본 연구를 통해 국내 음악치료 전문 학술지 연구동향을 파악 할 수 있으며 향후 음악치료 학문발전을 위한 연구의 양적 확대와 질적 제고가 필요함을 시사한다.
