In this paper, we propose a new code acquisition architecture having the features of low complexity and high speed for the MC-CDMA system. The newly designed searching finger has function of the searcher as well as the finger. The searching finger tests the PN code Phase as the searcher during the initial acquisition, and as the finger after the initial acquisition. The proposed system has reduced the average acquisition time of the PN codes to $T_{acq}$/19 in the 20MHz MC-CDMA system with 75% reduction of H/W complexity.y.

Objectives The purpose of this review is to analyze the trends of Korean medicine treatment for trigger finger. Methods Clinical papers using Korean medicine to treat trigger finger were searched in five online databases-Koreanstudies Information Service System, Oriental Medicine Advanced Searching Integrated System, ScienceON, Research Information Sharing Service, and PubMed. Nine studies were selected, and we analyzed their characteristics according to the author, year, number/gender/age of patients, duration of disease, duration of treatment, intervention method, measurement methods, and results. Results Seven case report studies, one prospective observational study, and one randomized controlled trials (RCTs) were selected in online databases, and there were no review studies. The most frequently used therapies were pharmacopuncture and acupuncture treatment. visual analogue scale, Quinnell's classification of triggering, was frequently used for measurement methods. All nine studies had therapeutic effects. Conclusions We reviewed studies of Korean medicine treatments for trigger finger, in this study. However, there are limitations that seven of the nine selected papers were case papers, and the number of papers was small. This paper suggests that a higher level of research and more studies on Korean medicine treatments of trigger finger need to be conducted.

The disadvantage of the general robot cleaner is that it works only on the designated route, so it is impossible to clean the place outside the designated route. Therefore, in this study, the direction control methodology for searching the place other than the designated route based on the finger recognition technology was studied to compensate for the shortcomings of the existing cleaner. Raspberry Pi was used as the main controller and Open CV program was used to recognize the number of fingers. To verify the validity of the proposed methodology, a finger recognition algorithm was implemented using Python language, and as a result of adopting the Logitech C922, the success rate was 100% at 90cm and 70% at 110cm, respectively.

Captured human motion data has been widely utilized for understanding the mechanism of human motion and synthesizing the animation of virtual characters. Searching for desired motions from given motion data is an important prerequisite of analyzing and editing those selected motions. This paper presents a new method of content-based motion retrieval without the need of additional metadata such as keywords. While existing search methods have focused on skeletal configurations of body pose or planar trajectories of locomotion, our method receives a three-dimensional trajectory as its input query and retrieves a set of motion intervals in which the trajectories of body parts such as hands, foods, and pelvis are similar to the input trajectory. In order to allow the user to intuitively sketch spatial trajectories, we used the Leap Motion controller that can precisely trace finger movements as the input device for our experiments. We have evaluated the effectiveness of our approach by conducting a user study in which the users search for dozens of pre-selected motions from baseketball motion data including a variety of moves such as dribbling and shooting.

Objectives : The purpose of this study was to review the acupuncture and moxibustion therapy for gastroesophageal reflux disease(GERD) in China. Methods : The literatures were searched using the database-China Academic Journals(CAJ)(~2015.1.). Clinical studies of acupuncture and moxibustion therapy for GERD such as randomized controlled trial(RCT), non-randomized controlled trial(NRCT), case series, or case report were included. Results : Thirty studies met our inclusion criteria: 24 RCTs, 4 NRCTs, 1 case series, 1 case report. Various kinds of treatment such as body acupuncture, abdominal acupuncture, acupuncture therapy with finger on back-shu point, electroacupuncture, acupoint injection, auricular acupuncture, and moxibustion were used in the clinical studies. The treatment groups take herbal medicines at the same time in 16 studies, and proton pump inhibitor(PPI) and histamine 2 receptor antagonist were used as a comparative treatment in the most of studies. Acupuncture or moxibustion treatments were done daily or 2~3 times a week for 5 days~18 weeks. All of studies reported higher effective rate in the acupuncture or moxibustion treatment group compared to the western medication control group. Conclusions : The results of this study could be used for the future practice and the clinical research about the acupuncture and moxibustion therapy for GERD.

Objective: The aim of this paper is to inquire into the influences form factors and control types affect a search time and comfort at list menu of full touch phone. Background: Various studies have been proceeded that are related to the optimum touch area for enhancing usability of control and legibility in mobile touch device. In the environment of list menu which is widely used to provide various information effectively, however, not only comprehensive consideration for legibility and control is to be seek but also research for control type which is to scroll a list. Method: This study executed form factor experiment to inquire into the influence that font size, height of row and fixed area affect searching time and comfort in the while information processing even if the information on the list is unsorted in alphabetical order. Among the result of form factor experiment, control type experiment was executed by selecting shortest performance time, highest legibility comfort and control comfort. Control type experiment was implemented to figure out the influence which existing flicking type, scrolling bar type, newly established button page type and button raw types affect performance time and subjective comfort depending on location of the information. Results: Font size 12pt, height of row 7mm and fixed area 15mm was shortest performance time and got highest comfort and legibility score in form factor experiment. A Button page which was newly proposed type was shortest performance time and got highest comprehensive comfort in control type experiment. Conclusion: Form factor experiment showed similar results with the study through reading a long passage of character or controlling a grid icon type. However, height of row turned out to affect not only touch area for control but also legibility by ruling space between the lines. Button page type which was newly proposed showed shortest performance time and got highest comprehensive comfort. Because Button page type needs few finger movements than other control types and implements search in the fixed form, unlikely other type which list keeps moving. Application: This study should be applied in deciding form factors and control type for scroll when designing a list menu of full touch phone.
