Pelvic actinomyces, usually a complication of an intrauterine device, is uncommon and may present a diagnostic dilemma because of an atypical clinical presentation. This organism is very difficult to culture, and most actinomyces is actually identified by histologic feature in pathologic specimens. Authors have experienced a case of pelvic actinomycosis associated with an intrauterine device and reported with a review of literatures.

In plastic surgery, patient photography is a vital component of clinical, educational, legal, and research documentation. Optimal acquisition of photographic data requires a dedicated photography studio or a three-dimensional anatomic scanner, both of which are financially impractical for most clinicians. Simplified photo standardization is proposed for use in random clinical settings by using a portable device called the Mirror Stand (MirS). This model device aims to mimic a studio environment by incorporating the basic elements of producing consistent photographs. The pilot MirS is designed for facial photography. Images of 40 random subjects were obtained using the MirS with three different cameras. Real anthropometric measurements of each subject were collected, compared with the photographic measurements, and analyzed. In this study, all three cameras produced equally reliable measurements. Actual facial measurements were comparable to the photogrammetric measurements obtained from photographs taken using the MirS. A constant formula was derived; it allowed the conversion of photographic values into real anthropometric values. The MirS produced consistent photographs with respect to the measurements. The photographs obtained could be translated reliably into their real anthropometric measurements. Therefore, the MirS can be applied in daily practice, providing an efficient alternative for obtaining a standard justifiable photograph.

This study evaluated the cosmetic effects of a far-infrared hot and cool mask (BBSkinplus) on face skin moisturization, whitening, and wrinkles using a randomized clinical trial. Forty female participants (mean age 47.7 ± 4.6 years) were allocated into the treatment group (BBSkinplus treatment and lotion application twice a day) or the control group (only lotion application twice a day), and moisture, brightness, and wrinkles were measured at 0, 1 and 2 weeks. The average values of each measurement were changed significantly by BBSkinplus treatment compared to the control group. At the 2-week treatment time point, the statistical differences in improvement rates between the two groups were significant at 8.7% vs. 3.9% for moisture (p < 0.01), 0.7% vs. 0.4% for brightness (p < 0.01), and -3.1% vs. 0.0% as Ra and -6.3% vs. 1.5% as R3z for wrinkles (p < 0.05), respectively. No notable complaint was reported regarding any kind of adverse effects such as erythema, itching, or burning. This clinical data support the potential of BBSkinplus as a home beauty device providing moisturizing, whitening, and anti-wrinkle effects on the face.

Purpose: The purpose of this research was to analyze the effects of an eye protective device and ear protective device application on sleep disorder with coronary disease patients in CCU. Methods: The research design was set up as a nonequivalent control group non-synchronized design. The subjects were coronary disease patients in the CCU of a tertiary hospital. The subjects were composed of 20 in the group with an eye protective device, 18 in the group with an ear protective device, 17 in the group with an eye protective device and ear protective device and 20 in the control group. The data was analyzed by $X^2-test$, ANOVA, Repeated measures ANOVA, Sheffe-test, Simple main effect and Time contrast using SPSS Win 12.0. Results: The hypothesis, 'There are significant differences in sleep quantity among the four groups' was supported (F=1,342.71, p=.000). The hypothesis, 'There are significant differences in the subjective evaluation of the general sleep patterns among the four groups' was supported (F=3,638.73, p=.000). In addition the hypothesis, 'There are significant differences in degree of sleep among the four groups' was supported (F=1,616.61, p=.000). Conclusion: It is cost effective and a simple eye protective device and ear protective device should be applied to patients according to their preference and characteristics in the clinical setting.

The purpose of this study was to develop a stuttering therapy device to aid in stutter therapy. The research method used for this study was as follows: First, the stuttering therapy device based on analysis of the prolonged speech method used at home and abroad was designed to achieve the goal of research. Second, the stuttering therapy device was to be developed to maintain a vocalization state, to use bio-feedback visualization, to have enough inspiration, to use Korean language in this device, and to use transfer and maintenance training in daily life. Third, the stuttering therapy device effectiveness was to be verified through use in clinical cases. The results of subjects receiving speech therapy and using the breathing control prolonged speech device and SI(stuttering Interview) evaluation programs for 3 months were as follows: For subject A, the stuttered word rate was reduced from 3.20 SW/M to 0.5 SW/M. For subject B, the stuttered word rate was reduced from 1.90 SW/M to 0.75 SW/M. For subject C, the stuttered word rate was reduced from 3.37 SW/M to 0.34 SW/M. For Subject D, the stuttered word rate was reduced from 0.51 SW/M to 0 SW/M. Follow-up evaluations verified the effectiveness of how the stuttering therapy device can reduce subjects' SW/M.

Although antiarrhythmic medication has been the main treatment modality for arrhythmia in children, in recent decades technological development and computerization have made great advances in nonpharmacological therapy. This article reviews the transcatheter radiofrequency ablation for tachycardia in children, recent advances of device therapy for bradycardia, antitachycardia pacing, implantable cardioverter defibrillator. As a new field of device therapy, cardiac resynchronization therapy for congestive heart failure is also mentioned.

We compared the clinical efficacy of LED therapy using 880 nm and 630 nm LED to test collagen accumulations in subcutaneous tissue of mouse after LED irradiation by measuring the quantity of collagen. 880 nm and 630 nm LED was irradiated on the back of ICR mouse given at $10.8J/cm^2$ followed for 30 minutes everyday for 5 weeks. Histological observation was performed by Hematoxylin & Eosin staining and Masson's Trichrome collagen staining. We also used Sircol soluble collagen assay kit for measuring the amounts of collagen in the mouse skin tissue after 1, 3, and 5 weeks post LED irradiation, respectively. Collagen generation was found at subcutaneous tissue, and the quantity of collagen in 880 nm LED group had grown more than that of 630 nm LED group at 5 weeks follow-up later. About 75% more efficacies for collagen generation were found in the group of 5th week of 880nm LED irradiation. The efficacy of 880nm LED could be more useful than 630 nm LED for synthesizing collagens in mouse subcutaneous tissue as time followed.

Using stretch sensors, a stuttering treatment training device that improve the abnormal breathing of stutterer was designed and developed. To improve stutterer's inadequate breathing method that is one of principal reason of stammering, the device estimates breathing method by checking the changes of the stretch sensor's resistances those are put on the chest and abdomen of user. And a vocal exercise program that carry out exercises only when the user maintains the abdominal breathing was designed. Using a PIC16C711 device that includes an A/D convertor, a main controller was designed and the vocal exercises software was developed using Director and C program with graphic user interface for user convenience. The controller sends the resistance data of sensors to PC through the serial port and the software verifies the breathing method. And the device was designed that the RTS (request to send) pin of serial port in PC is used as a power source so that it can work without any battery or other power source. Three stutterers have carried out the clinical experiments using the implemented device for two months and the results showed it was excellent to alleviate the stuttering.
