Cherubism is an uncommon, benign fibrosseous lesion of the jaws that causes a progressive, painless, symmetrical expansion of the maxilla and mandible. It's autosomal dominance pattern of inheritance has been confirmed. A characteristic deformity is specific to this disease: hypertrophy of the mandible, swelling of cheeks and sometimes hypertrophy of maxilla with eyes tending to look up ; that looks like the Renaissance cherubs. It usually makes figures during childhood between 2-4 years of age and progresses until puberty, after which it spontaneously regresses 10 most cases. As a result of this case review, the management strategies for cherubismic children in standpoint of pediatic dentistry can be summarized as follows: 1. It can be detected early in childen through its characteristic clinical and radiographic features, which is confirmed by histopathological examination and familial history. 2. The supervision of arch space is required against its frequent sequelae, the early missing of primary teeth and eruption disorders of permanent teeth. 3. It is highly recommended to continue the periodic check-up with clinical and radiographic examination, leading to surgical intervention in cases of aggravation.

Ultra high performance concrete (UHPC) has aroused interest around the world owing to superior mechanical and durability properties over conventional concrete. However, the application of UHPC in practice poses difficulties due to its inherent brittleness. UHPC filled in steel tube columns (UHPC-FSTCs) are capable of restricting the brittle failure of non-reinforced UHPC columns and forming a high performance member with enhancement of strength and ductility. Currently, research on UHPC-FSTCs remains very limited and there is relatively little information about the mechanical behavior of these columns. Therefore, this study presents a review of past experimental studies to have a deeper insight into the compressive behavior of UHPC-FSTCs under axial loading on entire section and on concrete core. Based on the test results obtained from Schneider (2006) and Xiong (2012), an analysis was conducted to investigate the influence of the confinement index (${\xi}$) and diameter to steel tube thickness ratio (D/t) on the strength and the ductility in short circular UHPC-FSTCs. Furthermore, the appropriateness of current design codes including EC4, AISC, AIJ and previous analytical models for estimating the ultimate loads of composite columns was also examined by the comparison between the predictions and the test results. Finally, simplified formulae for predicting the ultimate loads in two types of loading pattern were proposed and verified.

In the field of Radiology, the Computer Aided Diagnosis is the technology which gives valuable information for surgical purpose. For its importance, several computer vison methods are processed to obtain useful information of images acquired from the imaging devices such as X-ray, Magnetic Resonance Imaging (MRI) and Computed Tomography (CT). These methods, called pattern recognition, extract features from images and feed them to some machine learning algorithm to find out meaningful patterns. Then the learned machine is then used for exploring patterns from unseen images. The radiologist can therefore easily find the information used for surgical planning or diagnosis of a patient through the Computer Aided Diagnosis. In this paper, we present a review on three widely-used methods applied to Computer Aided Diagnosis. The first one is the image processing methods which enhance meaningful information such as edge and remove the noise. Based on the improved image quality, we explain the second method called segmentation which separates the image into a set of regions. The separated regions such as bone, tissue, organs are then delivered to machine learning algorithms to extract representative information. We expect that this paper gives readers basic knowledges of the Computer Aided Diagnosis and intuition about computer vision methods applied in this area.

Objectives: This study was performed to review the research trends in the treatment of eating disorder in traditional Chinese medicine (TCM). Methods: The CNKI database (China National Knowledge Infrastructure) was searched under the key words ‘Eating Disorder’, ‘Anorexia Nervosa’, and ‘Bulimia Nervosa’. Results: Thirteen articles were selected. These included 2 studies on bulimia nervosa, and 11 studies on anorexia nervosa. According to study design, studies were classified into 1 randomized controlled trial, 2 single group before-and-after studies, and 8 case reports. According to therapy method, they included 11 herbal medicine studies, and 2 complex treatment studies. The most common pattern identification was ‘liver qi depression’ (肝氣鬱結), and the most used herb was ‘Root of Bupleurum falcatum’ (柴胡). Most of the studies showed effective results. Conclusions: The results of our study indicated that TCM clinical studies on eating disorder were being conducted more actively than in Korean medicine. Korean medical treatment might be effective to relieve eating disorder symptoms. In the future, more scientifically designed clinical studies should be performed to prove the effectiveness of traditional Korean medicine treatment on eating disorder.

Background: The industrial revolution that took place in the United Kingdom (UK) between 1760 and 1830 led to profound social change. Occupational medicine was concerned with the diagnosis, treatment, and prevention of occupational diseases, that is, diseases directly caused by exposure to workplace hazards. A similar pattern of development has occurred globally. Methods: A review of relevant literature. Results: The international conceptualization and development of occupational health occurred during the 20th century. A new paradigm for occupational health has emerged that extends the classical focus on what might be termed "health risk management" that is, the focus on workplace hazards and risk to health to include the medical aspects of sickness absence and rehabilitation, the support and management of chronic noncommunicable diseases, and workplace health promotion. Conclusion: The future strategic direction for occupational health will be informed by a needs analysis and a consideration of where it should be positioned within future healthcare provision. What are the occupational health workforce implications of the vision for occupational health provision? New challenges and new ways of working will necessitate a review of the competence and capacity of the occupational health workforce, with implications for future workforce planning.

Human vocal cords vibrate as quickly as 100-250 times per second, so it is impossible to observe them with normal endoscopic diagnostic equipment. High-speed videolaryngoscopy (HSV) allows the visualization of non-periodic vibratory motion of vocal fold beyond the limitation of videostroboscopy. New developed post-processing methods that converts HSV to two-dimensional videokymography (2D VKG) using U-medical image-processing software can provide quantitative information on vocal fold mucosa vibration. Multifunctional laryngeal examination system is composed of 3 kinds of examinations such as HSV, 2D scanning digital kymography (2D DKG) and line scanning digital kymography (DKG). Evaluation of entire vocal cord vibratory pattern in each cord is possible using 2D DKG and a faster and more reliable quantitative information can be obtained. As this system is used in clinical and research, it is expected to bring much advances to the diagnosis of voice disorders. In this review, I will introduce the principles and advantages on examination of the vocal fold vibration, which is in the spotlight recently, and proceed with the literature review.

Amyotrophic lateral sclerosis (ALS) is a rapidly progressive neurodegenerative condition characterized by loss of motor neurons, resulting in motor weakness of the limbs and/or bulbar muscles. Pain is a prevalent but neglected symptom of ALS, and it has a significant negative impact on the quality of life of patients and their caregivers. This review outlines the epidemiology, clinical characteristics, underlying mechanisms, and management strategies of pain in ALS to improve clinical practice and patient outcomes related to pain. Pain is a prevalent symptom among patients with ALS, with a variable reported prevalence. It may occur at any stage of the disease and can involve any part of the body without a specific pattern. Primary pain includes neuropathic pain and pain from spasticity or cramps, while secondary pain is mainly nociceptive, occurring with the progression of muscle weakness and atrophy, prolonged immobility causing degenerative changes in joints and connective tissue, and long-term home mechanical ventilation. Prior to treatment, the exact patterns and causes of pain must first be identified, and the treatment should be tailored to each patient. Treatment options can be classified into pharmacological treatments, including nonsteroidal anti-inflammatory drugs, antiepileptic drugs, drugs for cramps or spasticity, and opioid; and nonpharmacological treatments, including positioning, splints, joint injections, and physical therapy. The development of standardized and specific assessment tools for pain-specific to ALS is required, as are further studies on treatments to reduce pain, diminish suffering, and improve the quality of life of patients with ALS.

Objectives : In this study, we aimed to analyze the latest knowledge of pityriasis rosea(PR) through oriental-western medical review on PR. Methods : We searched Pubmed, CNKI, and OASIS to select papers related to the cause, mechanism, diagnosis, classification, treatment, and herbal treatment of PR. Results : The results are as follows. 1. Although the exact cause of PR is not known, it has recently been found that reactivation of latent human herpesvirus-6 and human herpesvirus-7 infection is a possible etiology. Most patients require emollients, antihistamines, topical steroids, and macrolides. Acyclovir, and narrow-band UVB therapy are also used. 2. The cause and mechanism of PR in Chinese and Korean medicine can be mainly summarized as wind-heat, blood heat, and blood deficiency and wind-dryness. Most of the herbal medicine used have the effects of clearing heat, cooling the blood, detoxifying, dispelling wind, relieving itching, nourishing blood, and moistening dryness. Conclusions : In Chinese and Korean medicine, it is necessary to organize the representative prescriptions according to pattern identification, and it is also necessary to study the atypical types of PR and its treatment methods. It is thought that research on oriental and western combination therapy should be continuously conducted, and efforts to develop Korean medicine formulations are needed to revitalize clinical research in Korea.

This review aimed to examine and analyze trends of clinical research using case studies on facial spasms in Korean medicine. Seven web databases were searched for case studies on facial spasms using Korean and English search terms. Case studies were selected using the exclusion and inclusion criteria. Overall, 13 case studies were selected, analyzed, and classified according to the publication year and journal, study participants, cause, treatment methods, pattern identification, evaluation methods, improvement, and side effects. Case studies reporting on various treatment methods in Korean medicine, including acupuncture and pharmacopuncture for facial spasms, have been published since 2000. In addition, studies on new treatment methods in Korean medicine for facial spasm have been published. Combination therapy is the most common method used in Korean medicine-based case studies; therefore, future studies on single treatment are necessary. Most of the case studies on Korean medicine reported improved symptoms and patient satisfaction with the Korean medicine treatment method. No side effects were reported, except for facial swelling and bruising, indicating that Korean medicine treatment methods for facial spasm were safe and effective. Therefore, the Korean medicine treatment methods for facial spasm can be actively used in clinical practice and future research.
