Huangdi Neijing was completed during the several decades after Shijiand before Qilue, whose main content draws from the medical achievements of Qin and Han Dynasty, and is deeply influenced by Confucianism, Buddhism and Daoism of Qin and Han Dynasty. What creates the profound impact on its construction of medical theories are the thoughts of this period, such as "Valuing life", "people", "Valuing Yang", "Valuing earth", "the Heaven theory", "the Unity of Man and Nature", and the important works of this period, such as Huai Nan Zi, Chun Qiu Fan Lu, Shiji. Even the astronomy, calendar and medical achievements of this period are the basic material absorbed into the theories of Huangdi Neijing.

Orbital meningioma is a rare neoplasm that, even when suspected by CT or echographic examination, requires careful histologic study for precise identification. Fine needle aspiration(FNA) biopsy has become the diagnostic technique of choice in recent years for investigating orbital masses. There have been a few previous reports on FNA biopsy of orbital menigioma. We experienced a case of orbital meningioma in a 11-yr-old boy, diagnosed by FNA biopsy. The cytohistologic features of aspirated material (intranuclear inclusions, psammoma bodies, and cells arranged in whorls) made it easy to diagnose a meningloma.

The purpose of this thesis is to lay groundwork for the development of emergency care system in metropolitan area. It compares the performance and outcome of the current system with foreign counterparts and investigates the changing aspects of future medical environment. Emergency medical system can be divided into two parts of both pre-hospital care, which refers to the emergency measures taken before arriving at a hospital, and hospital care that is given within a hospital. Pre-hospital care includes on-the-spot expedients, information system and delivery system, whereas hospital care is related to the classification and specialization of medical care facilities. This research focuses on the evaluation of the performance of a rescue party, which is part of pre-historical care system. As a result, it provides valuable material for the development of the emergency medical system in Seoul.

Cold atmospheric plasma (CAP) is a material that generates free radicals through the ionization of air. Despite the application in various medical fields, the efficacy and safety of CAP on post-inflammatory hyperpigmentation due to atopic dermatitis have not been reported. Herein, we report the improvement in post-inflammatory hyperpigmentation of atopic dermatitis, after CAP treatment of three sessions weekly, 10 minutes per session. We examined the clinical severity indexes before and after treatment, including the Investigator's Global Assessment, modified Atopic Dermatitis Antecubital Severity, Eczema Area and Severity Index, and pruritus visual analogue scores. Our results indicate that CAP alleviates the post-inflammatory hyperpigmentation and clinical severity of atopic dermatitis, and effectively improves the atopic skin lesion without severe safety issues. We believe that the previously reported anti-bacterial effects and production of interleukin-6 after CAP treatment are probably responsible for the underlying mechanisms leading to clinical improvement.

A child being supported with an extracorporeal ventricular assist device, such as the Berlin Heart EXCOR (Berlin Heart GmbH, Berlin, Germany), must have at least 2 large cannulae for a long period. Management of cannula wounds is crucial since a cannula forms a track of prosthetic material passing the mediastinum to the heart. Deep wound complications, if they occur, can be troublesome and difficult to control with conventional methods. We applied vacuum-assisted closure to a patient who had Berlin-Heart EXCOR and a gap at the cannulation site. Herein, we describe the technical aspects of management in detail.

In this study, the sterilization property of E. coli was established using a plasma generator with a flexible electrode structure. The bacterial suspension was prepared based on the McFarland standard 0.50 (1.5×10⁸ CFU/mL) concentration and a specific amount was inoculated on the plate medium. After the plasma was discharged 3 cm away from the plasma generator in the range of 30s to 5 min and the results compared to the control group, the observed colonies that were formed decreased significantly as the plasma discharge time increased.

This paper place the focus the development of treadmill for rat in order to verify the effectiveness of exercise therapy. Up to now, in many medical laboratories treadmill have had to be remodeled for experiments with animal. Thus, it is necessary to develop the treadmills for animals only including rats. The treadmill has a DC motor which can make 600 revolutions per minute(600 RPM) and tension of the belt of the treadmill can be adjusted to prevent shift of the belt to any side. Velocity can be selected from 10m to 30m per minute increasing by 1m. The motor is controled by pulse width modulation(PWM) control mode using a 8bit microprocessor. In the future, the roller and motor need to be combined for improvement of stability and decrease of noise.

Infantile convulsion has always been the subject of concern as it is a common yet fatal disease among infants. During the Koryo dynasty and the early years of Chosun dynasty animal and mineral medicinal materials were used to relieve heat. These are replaced with more subtle medicinal materials later on in the Chosun dynasty when differentiation of chronic and acute infantile convulsion first emerged. As such, perception on appropriate medicinal materials is constantly renovated in the course of time.

The compressed fracture of spine caused by osteoporosis is one of the most frequent diseases in bone fracture. Recently the vertebroplasty has drawn much attention as a medical treatment for the compressed fracture of spine, which strengthens the vertebral body and corrects deformity, and relieves pain in patients by injecting bone cement. The finite element analysis is used to investigate the vertebroplasty quantitatively. Previous works with finite element analysis have drawbacks in their simplified models geometry of vertebral body and with material properties of bone. In this paper the exact geometry of vertebral body has been constructed from medical image data and the biomechanical property changes of vertebral body in vertebroplasty have been investigate by using three dimensional finite element analysis.
