Seoul International Computer Music Festival(SICMF) was held in the Jayu Theater, Seoul Arts Center at 13th-16th of October, 2016. It was hosted by Korean Electro-Acoustic Music Society(KEAMS). In this year, thirty-five works were selected and presented by various composers from Asia, Europe, and America, and French national music center - Grame was invited as guest composers and players. There have twenty-five live-electronic works, six tape works, and four audio-visual works been played for the five concerts during the festival. As for the live-electronic and instrumental compositions, the technology expands the capavility of acoustic instruments beyond their inherent limitation, and produce greater potentials in the category. The computer, furthermore, proves itself as a new-era alternate to a traditional musical instrument in this festival. As the number of computer-based music has increased in variously different ways, we should pay more attention to how computers would change the fundamental concept of music and what would get better in their environment and appreciation.

This paper proposes an improved Maximum Power Point Tracking method and design methods of unmanned solar vehicle system by parts of hardware, unmanned driving control and power conversion. The hardware design is offered on the weight reduction and structural reliability by using structural analysis software. The technique of curve fitting is applied to unmanned control system due to minimizing the vehicle’s behavior. Furthermore, lateral controller applying actuator dynamics is robust enough to prevent performance degradation by measurement noise regarding position and heading angle. The power conversion system contains battery charger system and tapped-inductor boost converter. In the battery charger system, variable step-size MPPT is conducted for quick response of maximum power point tracking. The validity of the proposed algorithm are verified by simulations and experiments.

Objectives : The purpose of this study was to investigate the characteristics and visiting patterns of traffic accident outpatients Methods : In this study, we reviewed the medical charts of 2,048 traffic accident patients who visited Jaseng Hospital of Korean Medicine from January 1st, 2012 to December 31st, 2012. Results : In the distribution of gender and of age patients, the male percentage was 52.3% and the majority of patients were in their thirties(47.2%). In the distribution of the patient's initial visit, most patients visited our clinic from Monday to Wednesday. By monthly distribution, the more patients visited the clinic at the latter half of the year. In the duration of treatment, 1,389 patients(67.8%) finished treatment within four weeks. The most frequently cited sites of pain were neck(82.0%), followed closely by low back(74.0%). In the access route, 746 patients(36.4%) visited our traffic accident clinic as a first choice for primary treatment. We referred patients for radiologic examination in 159 patients(7.9%), of which the exams were mainly lumbar spine MRIs(3.6%) and cervical spine MRIs(2.8%). The most frequent diagnosis were herniated nucleus pulposus. Conclusions : This study shows that most of the patients who visited the traffic accident clinic of a Korean Medical Hospital presented neck and low back pain, and the majority showed improvement without surgical treatment. Following the increasing minor injury rate caused by traffic accidents, we expect the role of Korean Medicine Hospital to become more prominent.

Objectives : The aim of this study is to assess the usage of diagnosis codes for somatic dysfunctions and the general characteristics of patients diagnosed with the code, by analyzing health insurance data provided by the Health Insurance Review & Assessment Service(HIRA) of Korea. This investigation is intended to outline future and willing to contribute to further use of diagnosis code and the approach of Oriental Medicine to somatic dysfunction. Materials and Methods : By analyzing HIRA data, those diagnosed with M99 codes, a code attributed to somatic dysfunction, were selected for analysis. Patients included were assessed for the relevant general characteristics, and the specific diagnostic criteria. The current usage rates and noteworthy characteristics of diagnostic codes of somatic dysfunctions were assessed. A comparative analysis between clinical departments and subcategories, and a comparative analysis to data of 2014 was conducted. Results : Patients given M99 codes constituted a small minority of all patients diagnosed in 2011 as shown by HIRA data. The codes were more frequently to older patients, females, outpatients, and those who filed for Health Insurance compensation. Medical institutions participating in the diagnosis were mostly primary care facilities, usually specializing in orthopedic(Western medicine sector) and internal medicine (Oriental Medicine sector). The most registered code in 2011 and 2014 was M995. The same trend can be observed in Oriental/Western medicine institutions and Public health center, on the other hand, between them, have some different patterns both 2nd and 3rd. Conclusions : This investigation is that of current usage of diagnostic codes of somatic dysfunction. HIRA insurance claim data was analyzed. Based on the current results, more precise diagnostic standards of somatic dysfunction are warranted. This study will provide a foundation for future Oriental Medicine approach to somatic dysfunctions.

본 논문에서는 Kinect 센서를 이용한 팔 제스처 인식 시스템의 설계에 대해 소개한다. 제스처 인식을 위한 기존의 연구들에서는 동적 시간 왜곡(DTW)에서 은닉 마코프 모델(HMM)에 이르기까지 다양한 방법들이 적용되어 왔다. 본 논문에서 제안하는 제스처 인식 시스템은 Kinect 센서를 통해 얻을 수 있는 순차적인 팔 관절 위치 데이터로부터 각 제스처 별 고유한 은닉 마코프 모델을 학습한다. 동일한 제스처를 수행하더 라도 Kinect 센서에 포착되는 각 관절의 위치 좌표 값들은 팔의 길이와 방향에 따라 크게 달라질 수 있다는 문제점이 있다. 본 논문에서 제안 하는 시스템에서는 다양한 환경 조건에서도 높은 제스처 인식 성능을 얻기 위해, 팔 관절들의 좌표 값으로 구성된 특징 벡터를 팔 관절들 간의 각도 값으로 변환하는 특징 변환 과정을 수행한다. 또한, 본 시스템에서는 은닉 마코프 모델의 학습과 적용의 효율성을 높이기 위해, 고차원 실 수 관측 벡터들에 k-평균 군집화를 적용하여 이산 은닉 마코프 모델들을 위한 1차원 정수 시퀀스들을 구한다. 이와 같은 차원 축소와 이산화를 통해, 실시간 환경에서도 은닉 마코프 모델들을 효율적으로 제스처 인식에 이용할 수 있다. 끝으로, 서로 다른 두 가지 데이터 집합을 이용한 실험을 통해, 본 논문에서 제안한 시스템의 높은 인식 성능을 입증해 보인다. This paper presents the design of an arm gesture recognition system using Kinect sensor. A variety of methods have been proposed for gesture recognition, ranging from the use of Dynamic Time Warping(DTW) to Hidden Markov Models(HMM). Our system learns a unique HMM corresponding to each arm gesture from a set of sequential skeleton data. Whenever the same gesture is performed, the trajectory of each joint captured by Kinect sensor may much differ from the previous, depending on the length and/or the orientation of the subject`s arm. In order to obtain the robust performance independent of these conditions, the proposed system executes the feature transformation, in which the feature vectors of joint positions are transformed into those of angles between joints. To improve the computational efficiency for learning and using HMMs, our system also performs the k-means clustering to get one-dimensional integer sequences as inputs for discrete HMMs from high-dimensional real-number observation vectors. The dimension reduction and discretization can help our system use HMMs efficiently to recognize gestures in real-time environments. Finally, we demonstrate the recognition performance of our system through some experiments using two different datasets.

Objectives Danggwisu-san (Dangguixu-san) is a herbal prescription frequently used to treat pain or swelling caused by contusion. To determine the expiration period through scientific methodology, stability of Danggwisu-san (Dangguixu-san) water extract, a herbal medicine, was examined under various storage conditions and periods. Methods Danggwisu-san (Dangguixu-san) was stored either at room temperature (23±2℃), under a refrigerating condition (4℃) or under a freezing condition (-18±2℃) for 0, 1, 2, 3 or 4 weeks and then freeze-dried. Total phenol and total flavonoid amounts were investigated; contents of amygdalin (Prunus persica), paeoniflorin (Paeonia lactiflora), and glycyrrhizin (Glycyrrhiza uralensis) - the marker compounds of Danggwisu-san (Dangguixu-san) - were also analyzed through high performance liquid chromatography (HPLC). Results No significant change in total phenol and total flavonoid amounts was observed under the indicated storage conditions. Moreover, the contents of marker compounds, i.e. amygdalin, paeoniflorin, and glycyrrhizin, did not alter significantly under the indicated conditions, as well. Conclusions Danggwisu-san (Dangguixu-san) was found to be stable up until 4 weeks under the indicated conditions. Further studies on efficacy and long-term stability are warranted to establish the expiration period of Danggwisu-san (Dangguixu-san). (J Korean Med Rehabil 2016;26(4):1-8)
