Understanding the biopsychosocial model of illness is crucial for any meaningful advance of health. The maintenance and promotion of health is achieved by different combinations of physical, mental, social and spiritual well-being. Health is not an objective of living. It is not only a state, but also a resource for everyday life. Health is a positive concept that emphasizes personal and social resources, as well as physical capacities. Understanding the biopsychosocial model of health and disease is very important in the medical system. George Engel challenged the medical profession to reconsider a strict biomedical approach to medical education and care, and to embrace a "new medical model," the biopsychosocial model. He argued that humans are at once biological, psychological, and social beings who behave in certain ways that can promote or harm their health. Although understanding the biopsychosocial model of illness is important, Korea's medical system have mainly been focusing on the biomedical model of illness. I would like to highlight the importance of biopsychosocial model of illness for Korea's medical system and real clinical field according to the 20th anniversary of Korean Society of Psychosomatic Medicine.

Psychosomatic medicine is also known as consultation-liaison psychiatry. Pediatric consultation-liaison psychiatry is composed of all consultation, liaison, diagnostic, therapeutic support and research activities carried out by psychiatrists and other mental professionals in pediatric ward to provide mental health services to physically ill pediatric patients. As the differences in the basic concepts of disease models between psychiatry (psychosocial model) and pediatrics(biomedical model) exist, active communication between the child psychiatrist and pediatric medical staffs is required. Although the general guidelines are similar, there are specific considerations for consultation in children and adolescents. Much work is still needed to identify empirically supported treatments which are effective for managing a board range of psychosocial difficulties in children and adolescents.

This paper investigated the biomedical medicalization of "depression"which is growing fast in Korea in terms of the treatment mechanism. Depression has been regarded as a mental disease that occurs with mixing various causations because what was the cause of this disease was not clarified until a recent date. Thus, as depression treatment, the medicine and the psycho-socio therapy have been used. However, from 1990s, as the brain science was introduced in the western society, and the high-tech diagnostic equipment of the brain disease and new drugs for the mental disease were developed, depression was rapidly redefined as 'the brain nerve system illness'that is easy to be taken and is able to obtain the permanent relief with the regular care. Under the influence of the redefinition of depression and the new treatment of it, recently, 8% of depression patients per year emerge as the aggressive cure subjects in the Korean psychiatric circle. However, according to the Korean psychiatric circle's unofficial calculation, it is estimated that only 10% of depression patients are receiving the accurate treatment but over 80% of the patients are not. If so, what does this estimation mean? Based on this question, this paper critically investigated the biomedical medicalization of depression.

PVDF(poly vinylidene fluoride) and P(VDF-TrFE)(poly vinylidene fluoride-tetrafluoroethylene) are the typical piezoelectric polymers with unique properties. Even they are inferior to conventional piezoelectric ceramics PZT in electromechanical conversion efficiency and interior loss, though they are superior in receiving sensitivity and frequency bandwidth. Their acoustic impedances are relatively close to water or biological tissue and it is easier to make thin film than other piezoelectric materials. Futhermore, the film is so flexible that it is easy to attach on a complex surface. Those properties are suitable for the ultrasound transducers which are useful for medical and biological application, so that various types of polymer transducers have been developed. In this paper, several important considerations for design and fabrication of piezoelectric polymer transducers were described and their effect on the transducer performance were demonstrated through the KLM model analysis. Then, it was briefly reviewed about the structures of the polymer transducers developed for obtaining images as well as the characteristics of the images in several important medical and biological application fields.

Due to the recent development of Information and Communication Technologies (ICT), the amount of research publications has increased exponentially. In response to this rapid growth, the demand of automated text processing methods has risen to deal with massive amount of text data. Biomedical text mining discovering hidden biological meanings and treatments from biomedical literatures becomes a pivotal methodology and it helps medical disciplines reduce the time and cost. Many researchers have conducted literature-based discovery studies to generate new hypotheses. However, existing approaches either require intensive manual process of during the procedures or a semi-automatic procedure to find and select biomedical entities. In addition, they had limitations of showing one dimension that is, the cause-and-effect relationship between two concepts. Thus;this study proposed a novel approach to discover various relationships among source and target concepts and their intermediate concepts by expanding intermediate concepts to multi-levels. This study provided distinct perspectives for literature-based discovery by not only discovering the meaningful relationship among concepts in biomedical literature through graph-based path interference but also being able to generate feasible new hypotheses.

최근 경조직 재생 (hard tissue regeneration) 에 대한 연구가 활발히 진행되고 있다. 그러나 이와같은 연구는 결손도입의 어려움 및 이차적인 골절의 위험성 때문에 대형동물을 중심으로 진행되고 있으며, 그 결과 동물실험에 있어서 시간적 경제적으로 큰 리스크를 수반한다. 그러나 유전자 변형동물의 대부분은 마우스이며, 분자생물학적 관점에서 골재생의 과정을 이해하기 위해서는 마우스를 이용한 골재생 모델의 확립이 필요하다. 따라서 본 연구에서는 마우스를 통해 경조직 재생모델의 제작방법을 검토함과 동시에, 골재생부위에 대한 골질 (bone quality) 및 골양 (bone quantity) 평가의 방법을 수립하는 것을 목적으로 하였다. 골결손은 생후 8주의 마우스에 시술하였다. 치과용 드릴을 이용하여 경골 (tibia) 길이의 30 % 부근의 내측(medial) 면에서 골수강 (marrow cavity) 방향으로 $500\;{\mu}m\varphi$의 원주형 결손을 도입하였다. 시술 후의 골재생과정을 관찰하기 위해 ${\mu}CT$ (SMX-100CT: Simazu) 를 이용하여 주기적으로 촬영하였으며, 골양 (BV/TV) 의 회복과정은3D-bon (RATOC) 을 이용하여 정량적인 해석을 수행하였다. 그리고 재생부의 골질 (아파타이트 배행성; BAp orientation) 평가는 투과형micro-beam XRD (R-AXIS BQ: Rigaku)를 이용하여 수행하였다.

The present study aimed to examine the effects of topical application of alendronate with a collagen membrane on the healing of the calvarial defect in rats, which has a good experimental design for the healing of tissue destruction, To study the effect of alendronate on bone healing, the collagen membrane containing $200{\mu}g$ alendronate was inserted in the defects of the right side and collagen membrane treated with physiologic saline was inserted in the defects of the left side. After 1, 2 and 4 weeks, observation of histologic feature after H&E staining, cell counting after TRAP staining, and hardness measurement(Knoop) were performed. In histologic finding, similar features were shown for both test and control groups each week. In cell counting only the 1 week test groups showed significant reduction of TRAP(+)cells than control groups(p<0.01) and the control groups showed statistically significant difference for 1, 2, 4weeks(p<0.05). In hardness measurement, The 2 week test groups showed significant higher hardness than control groups.(p<0,05) and not 4 weeks. There was significant increase of hardness for both groups as time goes by.(p<0.0l) Therefore local application of alendronate with collagen membrane was somewhat effective in reducing osteoclastic activity and increasing hardness in the early stage of healing. Further investigation concerning the actual effect of alendronate for bony healing will be necessary to apply the clinical cases

The purpose of this study was to present a educational content developed for training of dental extraction skill in a virtual environment. The development of the content consists of five steps: learning content analysis, draw a design model, development, test of validity, rectification and complete of the content. We developed the virtual reality (VR) simulator with producing an animation of surgical stages on the 3D models of human face for simulating dental extraction procedure. The results of validity tests for the content were mean 4.81 (SD, 0.72) for interface validity and mean 4.66 (SD, 0.71) for content validity, which represents strong evidence for the validity of the content. The data of the study indicates that the educational content developed for training of dental extraction skill using VR technology can be suitable to improve surgical skill of dental extraction in clinical field. We expect that further development of the education contents based on the VR technology to improve various surgical skills in clinical field will be addressed in the future.
