PURPOSE: The objective of this study was to determine the effectiveness of collagenated biphasic calcium phosphate (CBCP) as a carrier for bone morphogenetic protein-2 (BMP-2) at the early stage of healing in rabbit sinus. MATERIAL AND METHODS: In 16 rabbits, BMP-2-loaded CBCP was grafted into one sinus (the BMP group) and saline-soaked CBCP was grafted into another sinus (the CTL group). The groups were assigned randomly. After 2 weeks (n = 8) or 4 weeks (n = 8), radiographic and histological a

An individual's cardiovascular health is important. The measurement of blood pressure (BP) can be performed nonintrusively during normal daily activities. A study was designed to estimate systolic BP by measuring pulse arrival time (PAT) nonintrusively. PAT was obtained nonintrusively to estimate each individual's BP while he or she worked at a computer. Electrocardiogram (ECG) was measured with a capacitive-coupled electrocardiogram (CC-ECG) system and photoplethysmogram (PPG) was measured usin

US-TPVB could be a useful technique for sympathetic blockade in patients with upper extremity pain.

The genetic diagnosis methods by RT-PCR and Virion capture (VC)/RT-PCR against Rice stripe virus (RSV) were developed. Three diagnosis methods of seedling test, ELISA and RT-PCR were compared in virus detection sensitivity (VDS) for RSV. The VDS of ELISA for RSV viruliferous small brown plant hopper (SBPH) was higher with 40.5% than that of seedling test. The VDS of RT-PCR was higher with 21% than that of ELISA. The VDS of ELISA and VC/RT-PCR was same with 9.2% in average on the SBPH collected f

The abdominal draw-in maneuver (ADIM) is a method commonly used to reestablish neuromuscular control of the deep spine muscles among individuals with musculoskeletal problems. The purpose of this study was to evaluate the effect of ADIM combined with simulated weight-bearing (SWB) activities in the facilitation of the deep spine muscles. The subjects were 30 young healthy individuals. Ultrasound images were used to measure the relative changes in transverse abdominal (TrA), internal oblique (IO)

스크린 클라이밍은 스크린 스포츠의 하나로 컴퓨터 시스템에 의해 내용이 인공암벽에 투사되며 사용자와의 상호작용에 의해 진행된다. 본 논문에서는 어린이의 발달과정과 스포츠 클라이밍에 대한 동기부여에 초점을 맞추어 고대동굴탐험을 소재로 한 스크린 클라이밍 게임을 구현하였다. 게임의 내용은 프로젝터로 인공암벽에 투사하며, 사용자와의 상호작용은 키넥트의 뎁스 정보를 이용해 사용자의 입력을 받음으로써 이루어진다. 이 게임은 어린이 대상 전시 행사에서 높은 관심을 보였으며, 앞으로 추가적인 스크린 클라이밍 게임 구현이 이루어져야 한다.

OBJECTIVES: In Jang-jeom, a small village in Hamra-myeon, Iksan-si, Jeollabuk-do, South Korea, residents raised concerns about a suspected cancer cluster that they attributed to a fertilizer plant near the village. We aimed to investigate whether the cancer incidence in the village was higher than that in the general Korean population when the factory was in operation (2001-2017) and whether living in the village was associated with a higher risk of cancer. METHODS: Using national population dat

BACKGROUND: Stellate ganglion block (SGB) is a type of sympathetic block used to relieve pain in the face and upper extremities. However, its effectiveness can be limited by the presence of Kuntz fibers that bypass the stellate ganglion. Thoracic paravertebral block (TPVB) offers an alternative in such cases. We hypothesized that ultrasound (US)-guided TPVB would provide a higher success rate of upper extremity sympathetic blockade than US-guided SGB. Therefore, this prospective randomized study

Our results suggest that physicians must be aware of the serious complications related to opioids and health policies to prevent such complications and malpractice should be adopted.

Post-herpetic neuralgia (PHN) is one of the most painful diseases, which has made it a major concern for pain physicians. We aimed to quantitatively analyze the research outputs of studies on PHN published over the past 30 years using bibliometric analysis. We also aimed to analyze the research outputs of studies on interventional treatments for PHN and evaluate the academic achievements of Korean pain physicians. Bibliometric analysis was performed by searching the Web of Science database for P

BACKGROUND: Thoracic sympathetic ganglion block (TSGB) is a procedure to manage sympathetically maintained upper extremity pain (sympathetically maintained pain). To date, only a few studies have evaluated the clinical effectiveness of TSGB in pain medicine. This study investigated (1) the relationship between technical success of TSGB and pain reduction in patients with chronic upper extremity pain and (2) relevant clinical factors for a positive TSGB outcome. METHODS: We retrospectively review

Our study revealed academic achievements and growing interest in VR-related research in pain medicine. Researchers worldwide have shown balanced interest in applying VR technology to acute and chronic pain, with specific contributions from China, Japan, and South Korea. Harnessing VR technology is promising for improving pain management and enhancing patients' quality of life in the field of pain medicine.
