Objectives: A restrospective chart review were conducted to investigate the overall weight loss effect of the integrated Korean medicine treatment on obese patients (body mass index [BMI] ≥25 kg/m²) in Korean medicine clinic and analyze the difference in the effect according to lifestyle behaviors. Methods: The medical records of 43 obese patients were retrospectively analyzed including body weight, BMI, waist circumference, hip circumference, and body composition who received integrated Korean medicine treatment for 4 weeks at 24 Korean medicine clinics in Daejeon metropolitan city. All outcome measures were evaluated again 8 weeks after the end of treatment at week 12 for follow-up. EuroQol-5D (EQ-5D), the Korean version of the obesity-related quality of life scale (KOQOL) and patient's satisfaction were also evaluated. The analysis was divided according to the treatment period and observation period, and subgroup analysis was performed according to drinking and exercise habits. Results: Body weight, body fat, waist circumference, hip circumference, body fat were significantly reduced at week 4 and week 12. Theses weight reduction effects were significantly greater within treatment period (0 to 4 week) than observation period (4 to 12 week). Especially in the non-exercise group, the changes in body fat mass and body fat percent showed a significant difference between the treatment period and the observation period. KOQOL were also significantly improved at 12 week, but not in EQ-5D. No severe adverse events were observed. Conclusions: The integrated Korean medicine treatment could be effective to treat obesity including weight loss. It is necessary to prevent additional weight regain through regular exercise even after Korean medicine treatment.

The term megajournal is used to describe publication platforms, like PLOS ONE, that claim to incorporate peer review processes and web technologies that allow fast review and publishing. These platforms also publish without the constraints of periodic issues and instead publish daily. We conducted a yearlong bibliometric profile of a sample of articles published in the first several months after the launch of PeerJ, a peer reviewed, open access publishing platform in the medical and biological sciences. The profile included a study of author characteristics, peer review characteristics, usage and social metrics, and a citation analysis. We found that about 43% of the articles are collaborated on by authors from different nations. Publication delay averaged 68 days, based on the median. Almost 74% of the articles were coauthored by males and females, but less than a third were first authored by females. Usage and social metrics tended to be high after publication but declined sharply over the course of a year. Citations increased as social metrics declined. Google Scholar and Scopus citation counts were highly correlated after the first year of data collection (Spearman rho = 0.86). An analysis of reference lists indicated that articles tended to include unique journal titles. The purpose of the study is not to generalize to other journals but to chart the origin of PeerJ in order to compare to future analyses of other megajournals, which may play increasingly substantial roles in science communication.

통계적 공정관리절차의 특성은 해석적 해를 얻기가 어려운 경우가 많이 있으나 Markov연쇄를 적용하면 가능한 경우가 많이 있다. 이 논문에서는 공정 통계량이 Markov특성을 따르는 경우, Markov연쇄를 생성하는 방법과 이를 이용한 공정관리 절차의 특성을 도출하는 방법에 대해 설명하고 있다. 관리도의 통계적 설계, 경제적 설계 및 변량 표본 추출비 설계 등의 특성 규명을 위한 Markov연쇄의 적용에 대한 기존의 알려진 방법을 복습하고 또한 새로운 공정관리 분야인 재조정 관리도에의 적용방법에 대한 연구결과도 보여주고 있다. 공정관리의 특성연구에서 해석적 해가 가능한 경우에도 이 과정이 복잡하여 Markov연쇄를 병행 사용하면 특성 규명이 명확해지며, 모의실험보다는 짧은 시간에 더 정밀한 결과를 얻을 수 있어 널리 이용되고 있다.

Background An abnormally obtuse cranial base angle, also known as platybasia, is a common finding in patients with 22q11.2 deletion syndrome (22q11DS). Platybasia increases the depth of the velopharynx and is therefore postulated to contribute to velopharyngeal dysfunction. Our objective was to determine the clinical significance of platybasia in 22q11DS by exploring the relationship between cranial base angles and speech resonance. Methods In this retrospective chart review at a tertiary hospital, 24 children (age, 4.0-13.1 years) with 22q11.2DS underwent speech assessments and lateral cephalograms, which allowed for the measurement of the cranial base angles. Results One patient (4%) had hyponasal resonance, 8 (33%) had normal resonance, 10 (42%) had hypernasal resonance on vowels only, and 5 (21%) had hypernasal resonance on both vowels and consonants. The mean cranial base angle was $136.5^{\circ}$ (standard deviation, $5.3^{\circ}$; range, $122.3-144.8^{\circ}$). The Kruskal-Wallis test showed no significant relationship between the resonance ratings and cranial base angles (P=0.242). Cranial base angles and speech ratings were not correlated (Spearman correlation=0.321, P=0.126). The group with hypernasal resonance had a significantly more obtuse mean cranial base angle ($138^{\circ}$ vs. $134^{\circ}$, P=0.049) but did not have a greater prevalence of platybasia (73% vs. 56%, P=0.412). Conclusions In this retrospective chart review of patients with 22q11DS, cranial base angles were not correlated with speech resonance. The clinical significance of platybasia remains unknown.

Objectives: The purpose of this study is to report weight changes and analyze adverse events in diabetic patients with Gamitaeeumjowee-Tang for weight loss. Methods: A retrospective chart review of weight change and adverse events was performed during the 10-week weight loss program using Gamitaeeumjowee-tang with low-calorie diets for diabetics(n=61). Weight and BMI changes were compared before and after the program and calculated the percentage of people who lost more than 5% of their weight, also identified whether subjects felt satiated or not. Adverse events were evaluated in terms of causality, severity and system-organ classes. Results: After 10-week weight loss program, significant weight loss (5.9±2.32kg, 7.73% reduction from baseline) and BMI reduction (2.9±0.86) were reported (n=61). Those who lost more than 5 percent of their body weight accounted for 88.5%, and also 88.5% of the participants felt full to help control their appetite. In assessing the causality of adverse events, 'Unlikely' was the most common (66%) and in severity evaluations, almost all symptoms were mild. Insomnia was the most frequently reported during the first 8 weeks, and constipation was reported the most afterwards. Conclusions: A combination of Gamitaeeumjowee-tang and low-calorie diets for 10 weeks appears to help weight reduction without serious adverse events in diabetic patients. Future well-designed prospective clinical studies testing the effectiveness and safety of this weight loss program are warranted.

Objectives: The purpose of this study was to observe the effect of improving obesity after 4 week complex Korean medicine treatment in obese patients by retrospectively analyzing. Methods: A retrospective chart review was conducted on 44 patients who received obesity treatment at 23 Korean medicine clinics in Daejeon city. We analyzed weight, body mass index (BMI), body fat percentage, body fat mass, muscle mass, hip and waist circumference, EuroQol-5D (EQ-5D), Korean version of obesity-related quality of life scale (KOQOL), and satisfaction surveys at 4 and 8 weeks after treatment. Results: The weight, BMI change after 4 weeks and 8 weeks was decreased significantly. In addition, there were significant differences in fat mass, muscle mass, waist circumference, and hip circumference. Life quality scale EQ-5D and KOQOL showed decreased significantly. In the evaluation of overall satisfaction, safety, help level, recommendation intention, and revisit intention, more than 89% answered positively that they were satisfied. There were no serious side effects. Conclusions: It was significant effect on weight loss and obesity improvement after complex Korean medicine. And quality of life evaluation and satisfaction survey also show positive results.
