Objectives: The purpose of this study is to investigate the characteristics, validity, and reliability of non-radiological assessment tools of scoliosis that have been studied so far. Methods: Electronic databases including Pubmed, Cochrane Library, CNKI, Science On, RISS, OASIS were searched by keywords including 'scoliosis assessment', 'scoliosis screening', 'physical examination', 'functional measurement', 'photography', and 'smartphone'. Results: 32 articles using radiation-free assessments were identified from 1,011 records. The mostly used non-radiological methods were Surface topography, Scoliometer, Ultrasound, Digital Infrared Thermal Imaging, and Photography. The other methods were Gait analysis, 3D depth sensor imaging, and Low intensity electromagnetic scan. Conclusions: It was found that non-radiological assessment tools might reduce the number of radiographs taken in scoliosis patients. To increase the reliability and validity, further research on the measurement tools of scoliosis will be needed.

Magnetic Resonance Image (MRI) has been used as a safe, conventional and harmless diagnostic tool. However, thermal injuries have frequently been reported during MRI scanning due to the heat generated by the reaction with the magnetic field. It is recommended that metal-containing monitoring devices such as pulse oximetry and ECG monitoring leads should be removed prior to the start of the MRI scan, but these monitoring devices are inevitably placed in children or patients in the intensive care unit who have low compliance with the scan. Since the interaction between the metal probe or wire loop of pulse oximetry and the magnetic field can result in high thermal conduction, full-thickness burn can occur over the entire body surface during the MRI examination. Several cases of thermal burns from pulse oximetry on the fingers have been reported. However, we present a case of a full-thickness burn arising left earlobe in a 2-month-old child caused by the high conduction heat from pulse oximetry metal probe.

Objectives: This research aimed to develop a guideline for evaluating safety and performance of electronic warm-acupuncture apparatus. With the development of medical devices like electronic warm-acupuncture apparatus with improved performance, convenience and safety measures compared to traditional warm-acupuncture needling, safety and performance guideline is a necessity. Methods: By referring to existing standards and guidelines of other electronic devices for Korean medicine with heating function, guideline for safety and performance assessment of electronic warm-acupuncture apparatus was drafted Results: The guideline, presents explanation for adequate temperature and settings of the apparatus, and safety measurements providing against thermal runaway situations along with guidelines for the manual. Guideline for detailed test method for the performance of the apparatus such as accuracy of temperature increase and the timer, and safety unit was also provided. The test items and suggested test methods for the requirements of biological, electrical and electromagnetic safety were referred to Korean approval documents of ministry of Food and Drug Safety. Conclusion: We proposed the relevant items to verify performance and safety of warm-acupuncture apparatus to assure patient safety and improve the quality of currently developing devices for application in clinical field.

본 논문에서는 동적 추천 기능이 있는 자바 기반 음악 추천 서버를 소개한다. 본 논문에서 소개하는 추천 서버는 각 음악 사이의 유사도를 그래프로 저장하는 그래프 기반 협동적 여과 방식을 사용하며, 독립된 서버로 구성되어 클라이언트와 정해진 프로토콜에 따라 통신하도록 구현되었다. 또한 이 추천 서버는 특정 사용자나 특정 음악의 정적인(static) 성향뿐 아니라 시간에 따라 달라지는 동적인(dynamic) 성향에 맞는 추천도 가능하도록 설계되었다. 정적 성향이란 어떤 사용자가 가지고 있는 음악에 대한 기본적인 취향을 나타내고, 동적 성향이란 특정한 상황이나 분위기에 따라 유동적으로 변하는 성향을 의미한다. 본 논문에서 소개하는 추천 서버는 정적 성향과 동적 성향에 대하여 각각 추천할 수 있는 기능을 가지고 있으며, 이러한 기능을 바탕으로 실제 사용자들의 음악 다운로드 데이터를 이용하여 추천 데모 사이트를 구축하였다.

본 논문에서는 로봇이 정해진 폐구간을 이동하기 위해서 위에서 아래로 촬영한 카메라 정보를 활용한다. 로봇을 특정위치로 이동시키기 위해서는 카메라를 제어하는 서버 시스템과 로봇의 위치를 인식하기 위한 마크가 필요하다. 서버는 로봇의 위치를 로봇으로 인식하는 마크의 색 값으로 카메라로부터 인지하고 로봇에 위치 이동 명령을 수행할 서버와 로봇이 네트워크를 통해 Planning을 수행한다. 본 연구에서 휴머노이드 로봇인 나오와 로봇에 위치를 촬영할 카메라 그리고 이미지 처리를 하기 위해 OpenCV와 이동 알고리즘으로 $A^*$를 활용하여 Planning을 구현한다.

Objective: The aim of this case report was to describe the effects of traditional Korean medicine on a patient suffering from central dizziness caused by a lateral medullary infarction Methods: The patient was given a series of Korean medicine therapy treatments, including Jeseubsungi-tang, acupuncture, and cupping, for 37 days. We measured the progress of this case using a numerical rating scale (NRS). Results: After the treatment, the NRS score for dizziness decreased, and the headache almost completely subsided. Conclusions: This clinical case study indicated that Jeseubsungi-tang could be effective in relieving central dizziness and headache caused by lateral medullary infarction.

Ataxia and vertigo are frequent clinical findings in cerebellar infarction patients. In severe cases, they cannot achieve normal activity in daily life. A 65-year-old man was admitted with ataxia and vertigo diagnosed as acute cerebellar infarction. We prescribed for Chukdam-tang to treat the phlegm disease. After this treatment, ataxia and vertigo improved. We suggest Chukdam-tang is significantly effective on the treatment of cerebellar infarction.
