  • Food intake and swallowing are complicated and intriguing series of movements involving voluntary and involuntary activities of cranial and spinal nerves and muscles. They have two most important functions, that is, food passage from the oral cavity to stomach and airway protection. Tongue, buccinators, and hyoid bone and its muscular attachments are anatomic structures for swallowing of special interests. The swallowing process of liquid is commonly divided into oral preparatory, oral propulsive, pharyngeal, and esophageal stages according to the location of the bolus. The movement of the food in the oral cavity and to the oropharynx differs between eating solid food and drinking liquid.

  • Objectives: Tremor is a common disorder causing abnormal movements, it is defined as, "rhythmic, involuntary movements of a part of the body against ones own volition.". The purpose of this study is to report the effects of Korean Medicine (Acupuncture and herbal-medication) for oromandibular tremor resulting from Deficiency Syndrome. Methods: We treated 6 patients suffering from oromandibular tremor who received hospital treatment in DongEui Medical Center from March to June in 2015. Results: After the treatments, oromandibular tremor decreased or disappeared. And some other accompanying symptoms were improved. Conclusions: These results suggests that Korean medical treatments (Acupuncture and herb-medication) might be effective for treating oromandibular tremor resulting from Deficiency Syndrome.

  • Some wheelchair users with neuromuscular disorders experience involuntary extensor thrusts, which may cause injuries via impact with the wheelchair, cause the user to slide out of the wheelchair seat, and damage the wheelchair. Knowledge of the human-generated forces during an extensor thrust is of great importance in devising safer, more comfortable wheelchairs. This paper presents an efficient method for identifying human-generated forces during an extensor thrust. We used an inverse dynamic approach with a three-link human body model and a system for measuring human body motion. We developed an experimental system that determines the angular motion of each human body segment and the force at the footrest, which was used to overcome the mathematical indeterminacy of the problem. The proposed method was validated experimentally, illustrating the force-identification process during an extensor thrust.

  • 의료영상에서 인공물(Artifacts) 이라 함은 영상이 얻어지는 신체부위와 아무런 관련이 없으나 얻어진 영상에는 마치 영상의 일부분으로 나타나는 모든 것을 가리킨다. 따라서 영상에서 이들 인공물들은 실제 조직의 해부학적인 구조를 나타내지 않으므로 영상 판독에 영향을 주어 잘못된 진단을 초래할 수도 있다. 그러나 MR 영상이 가능한 이래로 새로운 여러 종류의 MR 인공물들이 많이 발견 되었으나 다행스럽게도 거의 모든 MR 인공물들은 쉽게 설명이 가능하며, 따라서 이들 인공물들에 의한 진단 오류의 가능성은 매우 희박한 실정이다. 그러나 새로운 영상방법이나 혹은 새로운 펄스대열이 계속 고안됨에 따라 새로운 종류의 인 공물들이 생겨날 가능성은 항상 존재하고 있다. 지금까지 알려진 여러 MR 인공물들은 그 생겨난 원인에 따라 다음과 같이 크게 세 가지로 분류가 가능하다.

  • Cranio sacral therapy is a refinend and subtle type of osteopathic treatment that encourages the realease of stresses and tentions throughout the body, including the head. Cranio sacral therapy is trained to feel a very subtle, rhythmical shape change that is present in all tissue. This is called Involuntary Motion or Cranial Rhythm. The movement is of very small amplitude therefore it takes practitioners with a very finely developed sense of touch to feel it. This Rhythm was first described in the early 1900's by Dr. William G. Sutherland and its existence was confirmed in laboratory tests in the 1960's and 1970's. Tension in the body disrupts the cranial rhythm. This shows them what stresses and strains your body is under a present and what tentions it may be carrying as a result of its past history.

  • The architectural space is the involuntary place where man lives and experiences, and as a 3 dimensional space through the continuous experience with the concept of 4th dimension of time, it provides the observers with the dramatic space imagery. These kinds of space experiences are experienced mentally and perceptively through the physical elements of inner and outer space of Museum, and this space imagery is created here by all the space composing elemensts of Museum. These space experiences are caused by the changing processes of the space characteristics, and the observers perceive the changes in space characteristics. These changing processes of inner and outer space, space versus space, and unit space, which are perceived by the observer, could be called as 'the transition' and the changes of the space characteristics as 'the transition characteristics'.

The present building is going with Eco-Architecture. When 2008 sees the building,,Eco-Architecture design which hits appears. There is a possibility of seeing 16 kind types from that place. And From here examined the spatiality which is expressed. These changing processes of inner and outer space, space versus space, and unit space, which are perceived by the observer.

  • The stereotactic surgical target for dystonic tremor is the subject of ongoing debate. Targeting the subthalamic area using deep brain stimulation has been regaining interest as a therapy for various types of involuntary movements. We describe the efficacy of stimulation of the subthalamic area in a patient with intractable dystonic tremor. Excellent control without neurological complications was achieved. This case report demonstrates that the subthalamic area is a valuable target for the control of dystonic tremor.

  • The subject collects information and constructs the outside world mainly through the sense of sight, though he cannot help but always see things from the viewpoint of the self-aware ego. While we are able to access the unconscious of which the latent desire is reflected in involuntary images and dream images, the substance of desire cannot be easily accessed due to the censorship of the ego and the super-ego, which makes images of the unconscious nonlinear, and allows us to pursue fantasies for pleasure. The original human desire to record and express visual objects has come true with technological fulfillments, and furthermore, digital technology has realized visual pleasure and desire, through simulation. The images that the unconscious produces and the images that digital technology produces are a visualization of objects by the subject's desire, and the subject realizes his pleasure through a visual fantasy. This study, based on the mechanism of the unconscious and the formal stamps of digital images, explores the interrelationship between the unconscious and digital images, both of which seek pleasure and desire.

  • The seakeeping performance can be defined as the ability of a ship to go to sea, and successfully and safely execute its missions even in adverse environmental conditions. From the viewpoint of safe operation, it is primarily important to estimate the seakeeping performance of a ship in a seaway. A method of evaluating navigational safety is presented by means of the integrated seakeeping performance index(ISPI) by measuring only vertical acceleration. Judgement of dangerousness is carried out for two types of naval vessels in applying the involuntary speed losses. The used models for computer simulation are Lpp 175m light aircraft carrier and Lpp 93m frigate. In developing the practical evaluation system of navigational safety, it is expected to be useful to solve the difficulties in measuring factors by sensors. The results are also useful for developing the optimum type of naval vessels by applying at the initial design phase.
