With increasing interest in the emotional responses to music, research on the regulatory mechanisms of music has been ongoing. This study examines the fidelity of music emotion regulation (MER) studies by analyzing the quality of rationales provided for using music to induce emotional regulation. A total of 45 internationally published studies were collected for review, and analysis was conducted on criteria related to the use of music, including duration, number of pieces, selection rationale, and the selecting agent. Despite the research objectives aiming to investigate the emotional regulation effects of music, it was found that the majority of studies lacked specific information about the music used, and there was weak consistency among the studies. Additionally, reliable evidence for music activities, music selection, and music implementation time was not provided, and there was a lack of logical basis for the regulatory mechanisms of music. The results of this study imply the necessity for fidelity to the rationale of music emotion regulation to establish itself as a research area. Such rigorous fidelity will contribute to increasing the replicability and integrity of research on the therapeutic uniqueness of music.

Pacemaker lead-related infective endocarditis is an uncommon, but serious complication. We report a case of a 45-year-old man who had symptom of intermittent high fever and rupture of sinus Valsalva that developed after a redo aortic valve replacement and transvenous permanent pacemaker implantation. Positive blood cultures of streptococcus viridans and transesophageal echocardiography showing a large mobile vegetation on pacemaker lead and tricuspid valve lead to the diagnosis of pacemaker lead-related infective endocarditis. Initial antibiotic therapy followed by surgical extraction of the pacemaker lead and wide debridement of infective tissues including multiple vegetations was required. Postoperative antibiotic therapy was continued for 4 weeks. The postoperative course has been uneventful. The patient is totally asymptomatic and is doing well up to now.

In this paper, we developed a pacemaker that can increase the efficacy of a left ventricular assist device (LVAD) and increase the survival rate for patients suffering end-stage heart failure. Because LVAD patients can experience arrhythmia, the pacemaker incorporated into the LVAD has the important role of sustaining sufficient blood circulation during arrhythmia. The electrode of the pacemaker is located at the apex of the left ventricle, where the VAD's inlet cannula is connected. This is efficient placement, in that the electrode can transmit electrical stimulation directly to the Purkinje fibers of the myocardium. The pacemaker can change the stimulation rate from 0 bpm to 191.4 bpm when a button is pressed on the external control module, and the pacemaker normally stimulates the heart at 60 bpm with 0.25 J of energy. We performed animal experiments to evaluate the performance and reliability of the combination of the LVAD and pacemaker. At pacemaker stimulation rates of 86.4 bpm, 100.2 bpm, 126.6 bpm, we recorded the ECGs, aortic pressures, and flow rates to analyze the heart loads.

This paper aims to propose a cost-based mechanical, electrical, and plumbing(MEP) coordination process using building information modeling(BIM). The proposed process can help project participants eliminate identified clashes between the MEP elements, analyze trends relating to MEP costs during the coordination process, and share their findings. MEP quantity-related information extracted through BIM was integrated with the cost database and schedule information. To check the applicability of the proposed process, it was applied to a construction project in South Korea. Through the application of the proposed process, MEP-related cost was reduced.

The most important indication for the removal of the lead-electrode system is the presence of an infection. When an infection occurs, the entire pacemaker system including the impluse generator and lead-electrode system should be removed. The entrapped electrode can be removed by a continous traction, by the use of forceps, snares or baskets, by the use of a locking stylet or a dilator sheath, and by an operation. We report a case that underwent a removal of an entrapped transvenous pacemaker electrode by the use of snaring technique.

본 논문에서는 Smith에 의해 제안된 이중 지연 라인을 갖는 양방향 디지털 도파관 모델을 SDL(sing1e delay line)모델로 변환하여 가야금의 단위 음이 만들어지는 과정을 나타내었다. 각 단계의 시스템은 선형적이며 단일 지연 라인과 LPF로 구성된다. 가야금의 임펄스 응답을 기본 입력신호로 하였으며. 실제 가야금의 조율 시스템인 안족은 선분 적합성을 이용한 근사화 과정을 거쳐 구현하였으며 이를 이용한 모의실험을 하였다. 실제 가야금을 조율하듯 안족에 의한 조율과 실제 음과 유사한 단위 음 생성을 할 수 있었다.

본 논문에서는 피부영상을 이용한 호흡 반영 음원 조율 방법을 제안한다. 얼굴 영상으로부터 호흡 신호를 추정하기 위해 ROI(Region of Interest)를 지정하고 지정된 영역의 색상 체계를 RGB에서 YCgCo로 변환한다. 피부 관심 영역으로부터 계산된 Cg색상 데이터 평균값에 필터링을 적용하여 호흡 신호를 검출한다. 검출된 호흡 신호를 통하여 사용자의 호흡 상태를 반영한 음원 조율방법을 제안하고, 이를 구현한 응용 프로그램을 소개한다. 구현한 응용프로그램의 성능평가를 위해 피험자 15명을 대상으로 블라인드 테스트와 MOS 평가방법을 사용하였으며, 실험 결과 9명의 피실험자가 호흡을 반영한 음원과 반영하지 않은 음원에 대한 차이를 느꼈다. 또한, MOS 평가방법으로 두 음원의 선호도를 조사한 결과 총 5점 만점 중 호흡을 반영한 음원이 4점, 원음이 3.6점을 얻었으며 이를 통해 피실험자들이 호흡이 반영된 음원을 선호한다는 결과를 확인하였다.
