The spray characteristics of Gas centered swirl coaxial in various injection condition was studied. The backlight image was used to capture the shape of spray and the electrical conductance method was used to measure the film thickness of spray at the end of injectors. The spray angle and film thickness was changed according to injection conditions.

Cryogenic swirl spray was investigated. Open type simplex swirl injector element was installed inside the high pressure chamber to find the effect of ambient pressure of the spray. Cryogenic swirl spray was unstable than conventional spray. Amplitude of surface wave on the spray was increased along ambient pressure, and instability frequency was decreased

This study was performed to analyze the recent trend of the studies about obesity in medicine and to provide background for futher studies. Methods: All of the article were selected in "The Korean Journal of Obesity". Search were conducted through "http://kosso.or.kr" with the search word "obesity". Collected articles were classified into clinical study, experimental study, literary study, case report. Results: One hundred eighty four studies were included and analyzed in terms of study design, subject, intervention, period, obesity index and so on. The numbers of clinical studies, literary studies, experimental studies, case reports were respectively 143 (77.7%), 26 (14.1%), 2 (1.1%) and 7 (3.8%). In clinical studies, observational studies were 112 (78.3%) and intervention studies were 31 (21.7%). And most of sample sizes were more than 100 and less than 499. Body mass index, waist circumstance, body fat percent were major criteria of clinical study. Most of the subjects on obesity were about relation with another disease or experimental results and diagnosis. According to classification by the kinds of intervention, diet, exercise, drug, behavior were respectively 22, 18, 8, and 8. More than fourty percent of intervention studies were studied for 12 weeks. Conclusions: To improve the quality of Korean Medicine study for obesity, we need to recruiting big sample size and activate randomized clinical trial.

Objectives The purpose of this study was to compare the effects of MSAT (Mostion style acuputure treatment) on piriformis muscle regarding leg radiating pain with HIVD of L-SPINE. Methods Forty patients who received inpatient treatment from Febuarary 1 to March 31, 2014 in the Daejon-Jaseng oriental medicine hospital were divided into 2 groups by blocked randomization : Group A (n=20)=routine treatment on HIVD of L-SPINE with MSAT on piriformis muscle and Group B (n=20)=routine treatment on HIVD of L-SPINE (acupuncture, Shinbaro pharmacopuncture, herb medication, chuna treatment and physiotherapy). The MSAT (Mostion style acuputure treatment) on piriformis muscle was administered each day and both groups were received routine treatment each day. Evaluations were made before treatment, after 3 days and 7 days, and before discharge using the NRS (numeric rating scale) and ODI (oswestry disability index). The statistically significance was evaluated by SPSS 18.0 for windows. Results Compared to before treatment, the NRS (numeric rating scale) and ODI (oswestry disability index) of both A and B groups after 3, 7 days and before discharge of treatment significantly decreased (p<0.05). Regarding group comparison, the NRS (numeric rating scale) and ODI (oswestry disability index) of A group was significantly lower than the B group at 3, 7 days, before dischanre (p<0.05). Regarding improvement of the NRS (numeric rating scale) and ODI (oswestry disability index), A group was significantly lower than the B group at 3 day (NRS), 7day (ODI) (p=0.000) but there was no significant difference between the two groups at 7 days (NRS) and before discharge (p>0.05). Conclusions Compared to just routine treatment, the MSAT (Mostion style acuputure treatment) on piriformis muscle significantly improved the NRS (numeric rating scale) and ODI (oswestry disability index) after 3, 7 days, and before discharge. Because early intervention determines the grade of Leg radiating pain with HIVD of L-SPINE, the MSAT (Mostion style acuputure treatment) on piriformisat the early stage will be clinically helpful to patients.

Objectives The purpose of this study is to report the improvement of complex Korean Medicine treatment for patients with rotator cuff injuries and determine the clinical improvement by number of damaged lesion. Methods Forty-one patients who diagnosed with rotator cuff injury were included in the retrospective study. Patients were treated with acupuncture, electroacupuncture and pharmacopuncture. Clinical outcomes were assessed using Numeric Rating Scale (NRS), Shoulder Pain and Disablity Index (SPADI) and EuroQol-5 Dimension Index (EQ-5D Index). Results Both NRS and SPADI scores were significantly reduced after treatment (p<0.01), but EQ-5D for assessing quality of life and clinical improvement by number of damaged lesion were no significant improvement (p>0.05). Conclusions These results show that patients with rotator cuff injuries could gain improvement from complex Korean Medicine. Further research is required to confirm the effectiveness of Korean Medicine treatment. (J Korean Med Rehabil 2018;28(4):81-87)
