The purpose of this study was to examine the influences of chronic shoulder pain on the muscle tone in trunk muscles. The study's subjects were 40 men and women in their 30 to 50s, which were divided into two groups. A chronic shoulder pain group consisted of 20 subjects who had been diagnosed with chronic shoulder pain by doctors, and a painless group consisted of 20 subjects who had experienced no such pain. An analysis was performed using electromyography on the muscle tone in the rectus abdominalis, external oblique, internal oblique, and erector spinae muscles under the same conditions between the two groups. The analysis results were as follows. The chronic shoulder pain group exhibited an overall high level of trunk muscle tone than the painless group, along with a statistically significant difference in the rectus abdominalis(p<.05). Moreover, the chronic shoulder pain group showed differences in the trunk muscle tone depending on the affected side. The chronic left shoulder pain group yielded higher levels of muscle tone in the right-side trunk muscles. In particular, the group revealed statistically significant differences in the rectus abdominalis and internal oblique(p<.05). The chronic right shoulder pain group exhibited higher levels of muscle tone in the left-side trunk muscles with a statistically significant difference in the internal oblique(p<.05). The above results suggested that chronic shoulder pain influences increases in the muscle tone in the trunk muscles on the opposite side to the affected shoulder.

Objectives This study is aimed to develop a Clinical Practice Guideline (CPG) on acupuncture treatment for the stroke patients with Post-stroke Urinary Incontinence(PSUI). Methods Experts committee, consisting of stroke or methodology specialists, searched Medline, EMBASE, Cochrane Library, China National Knowledge Infrastructure, and 19 Korean medicine journals. The search terms were selected to screen the randomized controlled trials (RCTs) or systematic reviews for the effectiveness of acupuncture on PSUI, compared with placebo or conventional group. Levels of evidence and grades of recommendations were appraised based on Recommendations for Development of Clinical Practice Guideline in Korean Medicine. Results & Conclusions 8 RCT were included to build the CPG. There was a strong evidence to support the effectiveness of acupuncture treatment for PSUI. The moderate evidence was presented that over 3 times a week of the acupuncture should be performed over 4 weeks on the acupoints, such as BL23, CV3, SP6, CV4, CV6, ST28, BL28, BL32, GV20, BL22, GV4 or ST36, for 15-30 minutes. 1-150 Hz frequency is suggested if electro-acupuncture treatments is performed with. It was also suggested that the procedure should begin at the acute stage just after the vital signs of the patients are stabilized. There was a moderate evidence to support safety of acupuncture treatment for PSUI. We recommend acu-points of constitutional acupuncture for Sasangin on the healthy side.

Objectives : The aim of this study was to investigate the characteristics of Hwa-Byung(HB) patients, draw the clinical key issue of HB, and provide the data as the basis for development of Clinical Guideline of HB. Methods : The study participants included 151 subjects who thought they have HB in 9 site. For all patients, we used HB epidemiologic study protocol, which include the Korean version of the Structured Clinical Interview for the DSM-IV Diagnosis (SCID-1), diagnostic criteria of HB, symptoms check list, pattern identification tool, psychiastric psychological questionaires, and Framingham coronary risk score(FRS). Results : 1. For all participants, 62 % of subjects were diagnosed with HB. These patients had comorbid DSM-IV diagnoses with depression (65%) and anxiety (27%). But 22% of these patients had only HB. 2. HB patients had various physical symptoms when visiting, were diagnosed as various disease, and undergone medical treatments in the past. Among the diagonsed illness, Gastronitestinal diseases (51.6%), psychiatric disorders(40.9%), endocrine diseases(39.8%) were being the most frequent. The frequent physical symptoms of HB patients reported were chest discomfort, head ache, pallpitation, frequent sigh, amnesia, shoulder pain, dry mouth, eye fatigue etc. 3. HB patients had high scores in psychologic questionares, CES-D, STAI, and STAXI. It means that HB patients might be low-level emotional stability. 4. Participant had negative opinion about the treatment of HB that it would be difficult or impossible (65.7%), but they neglect the need of medical treatment. Conclusions : This result shows that HB is comorbid with various psychiatric disease, but it has different physio-psychological symptoms from others and there were only HB patients. so we identify HB is independent disease. Moreover, there were the wrong perception of HB which blocking treatments. These problems support that the neccesity of development of Clinical Guideline of HB.

This study evaluated whether fluoride treatment can affect recovery of the irregularity of enamel surface after tooth whitening with a high concentration of hydrogen peroxide (HP) activated by plasma arc light. A total of 36 bovine teeth stained with coke were used in this experiment. The specimens were classified into following three groups (two different commercial plasma arc groups and a control group without light curing source): (1) 35% HP gel only, (2): 35% HP gel and Plasma arc A, and (3) 35% HP gel and Plasma arc B. To measure color changes and surface morphologies before and after the bleaching, colorimeter and scanning electron microscopy were used, respectively. When the specimens were bleached with hydrogen peroxide and plasma arc lights, the bleaching effect was greater than when only hydrogen peroxide gels were used (Kruskal-Wallis test, p<0.05). In addition, plasma arc B showed the more color changes than plasma arc A (Bonferroni post-hoc test, p<0.05). The surfaces of the teeth treated with fluoride gel after the whitening treatment came to be smooth. Therefore, the results of this study suggested that the fluoride application for patients who got tooth whitening therapy with a high concentration of hydrogen peroxide gels activated by plasma arc light will be effective to recover rough enamel surfaces.

The micro barrier rip array structures have been applied in a variety of areas including as privacy films, micro heat sinks, touch panel and optical waveguide. The increased aspect ratio (AR) of barrier rip array structures is required in order to increase the efficiency and performance of these products. There are several problems such as burr, defect of surface roughness and deformation and breakage of barrier rip structure with machining high-aspect ratio micro barrier rip array structure using orthogonal cutting method. It is essential to develop technological methods to solve these problems. The optimum machining conditions for machining micro barrier rip array structures having high-aspect ratio were determined according to lengths ($200{\mu}m$ and $600{\mu}m$) and shape angles ($2.89^{\circ}$ and $0^{\circ}$) of diamond tool, overlapped cutting depths ($5{\mu}m$ and $10{\mu}m$), feed rates (100 mm/s) and three machining processes. Based on the optimum machining conditions, micro barrier rib array structures having aspect ratio 30 was machined in this study.

Background: Although nicotine dependence plays a role as a main barrier for smoking cessation, there is still a lack of solid evidence on the validity of biomarkers to determine nicotine dependence in clinical settings. This study aimed to investigate whether urinary cotinine levels could reflect the severity of nicotine dependence in active smokers. Materials and Methods: Data regarding general characteristics and smoking status was collected using a self-administered smoking questionnaire. The Fagerstr$\ddot{o}$m test for nicotine dependence (FTND) was used to determine nicotine dependence of the participants, and a total of 381 participants were classified into 3 groups of nicotine dependence: low (n=205, 53.8%), moderate (n=127, 33.3%), and high dependence groups (n=49, 12.9%). Stepwise multiple linear regression model and receiver operating characteristic (ROC) curves analyses were used to determine the validity of urinary cotinine for high nicotine dependence. Results: In correlation analysis, urinary cotinine levels increased with FTND score (r=0.567, P<0.001). ROC curves analysis showed that urinary cotinine levels predicted the high-dependence group with reasonable accuracy (optimal cut-off value=1,000 ng/mL; AUC=0.82; P<0.001; sensitivity=71.4%; specificity=74.4%). In stepwise multiple regression analysis, the total smoking period (${\beta}$=0.042, P=0.001) and urinary cotinine levels (${\beta}$=0.234, P<0.001) were positively associated with nicotine dependence, whereas an inverse association was observed between highest education levels (>16 years) and nicotine dependence (${\beta}$=-0.573, P=0.034). Conclusions: The results of this study support the validity of using urinary cotinine levels for assessment of nicotine dependence in active smokers.

SONAR detection performance is one of the key survivability factors in underwater weapon systems. In order to catch the acoustic ability of SONAR, multilayer SONAR structures are analyzed using the elastic theory. The applied results for the simple models are compared with those from commercial program, ANSYS, and the reliable results are obtained. The analysis of sound pressure level (SPL) and echo reduction (ER) by the thickness change of multilayer SONAR structures are performed using the verified elastic theory. As the thickness of anechoic layer is increased, SPL is distributed evenly and ER is increased slightly with the frequency. In decoupling layers and steel layers, SPL are hardly changed and ER is slightly decreased with the thickness increase of those layers. SPL and ER are not affected by the thickness change of the carbon reinforced plastic (CRP) layer. Therefore, to improve the acoustic ability of multilayer SONAR structures, the thickness increase of the anechoic layer and minimization of the decoupling layer, steel layer and CRP layer are desirable.
