Objectives: This study measured the thickness of the abdominal wall at abdominal acupoints using ultrasonography and then investigated the correlations between the thickness of the abdominal wall and other characteristics of patients with functional dyspepsia (FD). Methods: Thirty patients with FD were enrolled in the study from September 2015 to March 2016. The thickness of the abdominal wall was measured at Shangwan (CV12), Zhongwan (CV13), and the left Liangmen (ST21). In addition, height, weight, body mass index (BMI), duration of FD, and the sternocostal angle were investigated. The severities of spleen qi deficiency and the dyspepsia symptoms were assessed by the Spleen Qi Deficiency Questionnaire (SQDQ) and the Nepean Dyspepsia Index-Korean version (NDI-K). Results: The average thickness of the abdominal wall was $24.66{\pm}6.69mm$ at Shangwan, $21.17{\pm}5.83mm$ at Zhongwan, and $21.72{\pm}5.72mm$ at Linagmen, and there were significant differences between the thickness at Shangwan and Zhongwan (p=0.046). Furthermore, there were significant differences between the thickness of the abdominal wall at Zhongwan and the sternocostal angle (r=0.396, p=0.037). Conclusions: These findings indicate the possibility of estimating the thickness of the abdominal wall by looking at the characteristics of patients with FD, including the sternocostal angle.

3차원 모델은 현재 많은 분야에서 사용되고 있다. 특히 기존 평면의 지도에 비해 3차원으로 제작된 지도는 현실감이 뛰어날 뿐만 아니라 제한된 평면 지도 안에서 얻을 수 없는 다양한 정보를 제공 할 수 있기 때문이다. 본 논문에서는 지금까지 모델링을 위해 사용되었던 고가의 레이저 스캐너를 대체하여 디지털 카메라 스테레오 매칭 알고리즘의 성능 개선을 통하여 쉽고 빠르게 양산 할 수 있는 프로세스를 제안하였다. 본 연구에 사용된 알고리즘은 OpenCV 라이브러리 내에 포함되어있는 SURF 알고리즘이며 알고리즘이 가지고 있는 부정합 점들을 호모그라피 변환과 에피폴라 라인을 이용하여 제거하였다. 또한 개선된 알고리즘을 상용프로그램과 비교하였으며 상용프로그램에 비하여 성능이 우수한 것으로 확인하였다. 제안된 방법은 스테레오 매칭의 조건을 만족한다면 쉽고 빠르게 3차원 모델링을 할 수 있기 때문에 각종 디지털 지도나 3차원 가상 현실 분야에 크게 기여할 것으로 예상된다.

Purpose: The study aims were to develop a wearable inertial sensor-based gait analysis device that uses machine learning algorithms, and to validate this novel device using temporal gait parameters. Methods: Thirty-four healthy young participants (22 male, 12 female, aged 25.76 years) with no musculoskeletal disorders were asked to walk at three different speeds. As they walked, data were simultaneously collected by a motion capture system and inertial measurement units (Reseed®). The data were sent to a machine learning algorithm adapted to the wearable inertial sensor-based gait analysis device. The validity of the newly developed instrument was assessed by comparing it to data from the motion capture system. Results: At normal speeds, intra-class correlation coefficients (ICC) for the temporal gait parameters were excellent (ICC [2, 1], 0.99~0.99), and coefficient of variation (CV) error values were insignificant for all gait parameters (0.31~1.08%). At slow speeds, ICCs for the temporal gait parameters were excellent (ICC [2, 1], 0.98~0.99), and CV error values were very small for all gait parameters (0.33~1.24%). At the fastest speeds, ICCs for temporal gait parameters were excellent (ICC [2, 1], 0.86~0.99) but less impressive than for the other speeds. CV error values were small for all gait parameters (0.17~5.58%). Conclusion: These results confirm that both the wearable inertial sensor-based gait analysis device and the machine learning algorithms have strong concurrent validity for temporal variables. On that basis, this novel wearable device is likely to prove useful for establishing temporal gait parameters while assessing gait.

Objectives: The present study evaluated the effects of sa-am acupuncture (SAA) simpo-jeongkyeok (SPJK) treatment on the blood pressure (BP), pulse rate (PR), and body temperature (BT) of patients with hwa byung (HB). Methods: This patient assessor blind, randomized, placebo controlled trial included 50 volunteers, divided randomly into two groups. The treatment group underwent SPJK (PC9, LR1, PC3, KI10) while the control (sham) group received minimal needle insertion at non acupoints. The BP in both arms, PR, and BT at several acupoints were measured before and after treatment at the $1^{st}$, $2^{nd}$, $3^{rd}$, and $4^{th}$ visits and before treatment at the follow-up visit. We analyzed data by using the repeated measured analysis of variance (RM ANOVA), Mann-Whitney U, and wilcoxon signed rank tests; differences at P < 0.05 were considered significant. Results: No significant differences in the systolic blood pressure (SBP), diastolic blood pressure (DBP) and PR between the treatment and control group were observed at each visit. However, the decrease in the SBP for the treatment group before and after each visit was significantly higher than it was in the control group. The SBP in both arms in the treatment group was decreased between visits 1 and 2, 1 and 3, 1 and 4, and 1 and follow-up. The DBP in both arms and in the right arm between visits 1 and 3 in the treatment group showed decreases. A minimal BT increase for treatment at CV06 and CV12 and a minimal BT decrease for treatment at CV17 and (Ex) Yintang were found. Patients in the treatment group who visited more frequently experienced a greater decrease in the PR, but that effect was not maintained. Conclusion: The results suggest that SAA SPJK treatment has instant positive effects on the BP, PR, and BT in patients with HB, but the effects on the BP and PR are not maintained.

Background: The basic concept of thermographic interpretation is the thermologic equality of both side in normal person. But both sides diseases were limited diagnostic values by thermographic interpretation, and this interpretation does not apply to the case in thermal temperature of each part of body. Nevertheless, the measurement conditions are not standardized. So, for its clinical applications are extended, we think that the measurement conditions are considered the individual variations. Objectives: The purpose of this study is to examine the optimum conditions thermal temperature of the time period and region are not effected by internal and external variables. Methods: After the subjects took off their clothes, the filming were repeatedly five times made on duration of 5minutes during 20minutes. We selected nine regions around acupoints including Yin dang[印堂, HN1], Sugu[水溝, GV26], Ch’ondol[天突, CV22], Chonjung[CV17], Chung-wan[中脘, CV12], Ch’onch'u[天樞 S25], No-gung[勞宮, P8], and calculated based on the utility of R.O.I.(Region of Integer) in our system these points temperature. We measured the optimal time period and region that has little variation of thermal temperature. Results: The results shows that the optimal time period is 20minutes after undressed, and the optimal region is the region around acupoints including Sugu[水溝, GV26]. Conclusions: we obtained the measurement conditions were considered the individual variations. And also, this study offers basic sources for that the measurement conditions would be standardized. Furthermore, based on this results, we expect that clinical applications using thermography would be extended.

청각장애인들은 수어통역 없이 상담서비스를 이용하기에는 어려움이 있다. 수어 통역사 인력이 많이 부족하여 수어 통역사까지 상담이 연결되는데 많은 시간이 걸리거나 연결이 되지 않는 경우가 많이 발생하고 있다. 이에 본 논문에서는 OpenCV와 CNN(Convolutional Neural Network)을 이용하여 수어를 영상으로 촬영하고 수어 동작을 인식하여 수어가 뜻하는 의미를 텍스트 형태의 데이터로 변환하여 사용자에게 제공하는 시스템을 제안한다. 상담사는 저장된 수어번역 상담내용을 열람하여 상담을 진행할 수 있다. 전문 수어 통역사가 없어도 상담이 가능하여 수어 통역사를 기다려야 하는 부담을 줄일 수 있다. 제안 시스템을 청각장애인 상담서비스에 적용할 경우 상담 효과의 향상과 향후 청각장애인 상담에 관한 학문적 연구를 촉진하는 계기가 될 것으로 기대된다.
