Cold atmospheric plasma (CAP) is a material that generates free radicals through the ionization of air. Despite the application in various medical fields, the efficacy and safety of CAP on post-inflammatory hyperpigmentation due to atopic dermatitis have not been reported. Herein, we report the improvement in post-inflammatory hyperpigmentation of atopic dermatitis, after CAP treatment of three sessions weekly, 10 minutes per session. We examined the clinical severity indexes before and after treatment, including the Investigator's Global Assessment, modified Atopic Dermatitis Antecubital Severity, Eczema Area and Severity Index, and pruritus visual analogue scores. Our results indicate that CAP alleviates the post-inflammatory hyperpigmentation and clinical severity of atopic dermatitis, and effectively improves the atopic skin lesion without severe safety issues. We believe that the previously reported anti-bacterial effects and production of interleukin-6 after CAP treatment are probably responsible for the underlying mechanisms leading to clinical improvement.

Ever-evolving diverse communication tools bring numerous changes and improvements into the lives of humans. It is extremely important to provide visual information when communicating with consumers in the commercial arena because humans acquire over eighty percent of the information around them through sense of sight. One cannot compete with just sheer quality in today's world. Therefore, the applications of digital technology in the visual merchandising became crucial, for it can dramatically improve the market value. Among these applications is digital signage, a new media for esthetic experience. I strongly believe that this would be a new marketing tool for the brand's distinctive and unique publicity. This research has been conducted in order to find out how the fast-growing digital signage, defined by the contents, has become not just a mere digital video clip but an esthetic merchandising tool that can produce various effective marketing strategies; and to discover the characteristics that this application has brought out in the visual merchandising field of fashion stores' global SPA brands. Based on the market case study, analyses have been made for the digital signage types and strategies regarding the visual merchandising expressive elements and for the effects the digital signage application will have on publicity. According to the results, the digital signage has proven to be informative, diversely applicable and contributes greatly to the increase in sales and to the improvement of company and brand image. Thus, it is much more than just a media tool for advertisement.

The performance of a tracking system is greatly increased if multiple types of sensors are combined to achieve the objective of the tracking instead of relying on single type of sensor. To conduct the multi-modal tracking, we have previously developed a multi-modal sensor-based tracking model where acoustic sensors mainly track the objects and visual sensors compensate the tracking errors [1]. In this paper, we find a network synchronization problem appearing in the developed tracking system. The problem is caused by the different location and traffic characteristics of multi-modal sensors and non-synchronized arrival of the captured sensor data at a processing server. To effectively deliver the sensor data, we propose a time-based packet aggregation algorithm where the acoustic sensor data are aggregated based on the sampling time and sent to the server. The delivered acoustic sensor data is then compensated by visual images to correct the tracking errors and such a compensation process improves the tracking accuracy in ideal case. However, in real situations, the tracking improvement from visual compensation can be severely degraded due to the aforementioned network synchronization problem, the impact of which is analyzed by simulations in this paper. To resolve the network synchronization problem, we differentiate the service level of sensor traffic based on Weight Round Robin (WRR) scheduling at the routers. The weighting factor allocated to each queue is calculated by a proposed Delay-based Weight Allocation (DWA) algorithm. From the simulations, we show the traffic differentiation model can mitigate the non-synchronization of sensor data. Finally, we analyze expected traffic behaviors of the tracking system in terms of acoustic sampling interval and visual image size.

Visual evaluation of rib shadow and lung marking during high voltage chest radiography. The Purpose of this study is to improvement of visual discrimination of pulmonary structures on the conventional chest radiogram. The author prepared an artificial lung using an acryl plate, 8 cm in thickness, which is nearly equivalent to human lung, and 0.6 cm thickness of an aluminum plate for an artificial rib, and 0.5 cm of an acryl plate as a pulmonary vessel as well. And they were used as objects for experimental radiograms. This study performed with gradual increasing densities of film bases in the sequences of densities of 0.6, 0.9, 1.1 and 1.3. We made two combinations of images after multiple and regular cuts, with width of 1 cm, of 4 radiograms at the above mentioned densities of film bases. One image consisted of alternative combination of radiograms taken at densities of 0.6 and 1.3, and the other did at 0.9 and 1.1. The latter image provided better visual perception of pulmonary structures than the former. Experimental radiograms were also taken with 60 kV and 120 kV respectively. After careful evaluation and comparison to images taken on varieties of different densities with combinations and kV, the author had a conclusion that it is advisable to use a high kV X-ray which makes rib shadow subtle, for better visual delineation of pulmonary structures behind ribcage, eventhough contrast of pulmonary structures are decreased at high kV radiogram.
