1. Objects of Research This research is purposed to find role and treatment mind of Sasang constitutional medicine in human genome age, through summarizing recognition of human and etiology. treatment on diseases proposed in Sasang constitutional medicine 2. Methods of Research It was researched as bibliologically with Dong-mu's chief medical writings such as ${\ulcorner}Dongyi$ Soose Bowon(東醫壽世保元)${\lrcorner}$, ${\ulcorner}$Dongyi Soose Bowon Sasang Chongyun(東醫壽世保元四象草本卷${\lrcorner}$. 3. Results and Conclusions 1. The outlook on human of Sasang Constitutional Medicine was completed in the base on Confusianism and it recognized that human is consisted with congenital element based on 'Human nature-shape' and acquired element based on Knowledge-Acting. Dong-mu emphasised acquired element than inborn element. 2. Sasang Constitutional Medicine is thought that we ran overcome inborn limitation of each constitution through moral culture of aposteriori Knowledge-Acting. and that self-correction is methods which is applied to treatment of disease recovering Essential Qi of each constitution with moral culture of personality 3. Sasang Constitutional Medicine is recognizing Essential Qi by main standard that foretell prognosis of disease and emphasize recovery of Essential Qi through self-correction than way of 'Assisting-Good Qi' and 'Removig-Bad Qi' in treatment of disease. 4. Self-correction can be divided into non-herbal self-correction and herbal self-correction. Non-herbal self-correction is to control greed by aposteriori Knowledge-Acting and herbal self-correction is to recover Essential Qi by herb. 5. It is thought that the present constitutional disease is consisted by accumulating life habit nature of a disease of ordinary times, and Sasang Constitutional Medicine that present constitutional disease is treated through administration of life habit nature of a disease of ordinary times in Sasang Constitutional Medicine. 6. Treatment mind to correct oneself into Golden Mean through controlling Knowledge-Acting in Sasang Constitutional Medicine may get into important treatment guide of gene medicine age.

A 3D human ventricular model is proposed to simulate an integrative analysis of heart physiology and blood hemodynamics. This consists of the models of electrophysiology of human cells, electric wave propagation of tissue, heart solid mechanics, and 3D blood hemodynamics. The 3D geometry of human heart is discretized to a finite element mesh for the simulation of electric wave propagation and mechanics of heart. In cellular level, excitations by action potential are simulated using the existing human model. Then the contraction mechanics of a whole cell is incorporated to the excitation model. The excitation propagation to ventricular cells are transiently computed in the 3D cardiac tissue using a mono-domain method of electric wave propagation in cardiac tissue. Blood hemodynamics in heart is also considered and incorporated with muscle contraction. We use a PISO type finite element method to simulate the blood hemodynmaics in the human ventricular model.

Fracture analysis of human bone is necessary to predict the failure of musculoskeletal structures and to heal them by several possible mechanisms under different loading conditions. But human bone is a complex material, with a multiphase, heterogeneous and anisotropic microstructure. Due to the difficulty of obtaining experimental and clinical results, the importance of numerical analysis and computational simulations in biomechanics are increasing gradually. In this study, stress analysis for human femur model is performed by using the 2-dimensional finite element method(FEM) and its stress distribution is determined. From these results, the fracture mechanic parameters are calculated and the fracture criteria on human femur are investigated and discussed.

The management of safety at sea is based on a set of internationally accepted regulations and codes, governing or guiding the design and operation of ships. The regulations most directly concerned with human safety and protection of the environment are, in general, agreed internationally through the International Maritime Organization(IMO). IMO has continuously dealt with safety problems and, recognized that the human element is a key factor in both safety and pollution prevention issues(IMO, 2010). This paper proposes a human error analysis methodology which is based on the human error taxonomy and theories (SHELL model, GEMS model and etc.) that were discussed in the IMO guidelines for the investigation of human factors in marine casualties and incidents. In this paper, a cognitive process model, a human error analysis technique and a marine accident causal chains focused on human factors are discussed, and towing vessel collision accidents are analyzed as a case study in order to examine the applicability of the human error analysis technique to marine accidents. Also human errors related to those towing vessel collision accidents and their underlying factors are discussed in detail.

필기체 문자는 인쇄체 문자와는 달리, 복잡한 변형이 따르므로, 인식 하는데 많은 문제점이 따른다. 그렇기 때문에 일반적인 필기체 인식에 있어서는 필기 자체에 대한 제한을 두어 변형을 적게한 문자를 인식 대상으로 삼고 있다. 이러한 문자는, 설정된 조건만 확실하게 만족한다면, 비교적 간단하게 인식 할 수 있다. 반면에, 자유 필기체 문자는, 제한 필기체 문자와는 달리 변형이 크기 때문에, 그 인식에는 많은 연구가 필요하다. 본 연구에서는, 자유 필기체 한글의 자모를 추출하는데 있어 두개의 parameter space method를 이용했다. 화상내에서의 혼합은, 기본적으로 5 개의 element ($\mid,\;\setminus,\;/,\;-,\;o$)로 구성되어 있고, 이 element를 정의하는데는 최소한 4 개의 parameter, 즉 element의 위치 [x, y], 크기 [1] 및 type [T] 등이 필요하다. 입력 화상에서 추출된 직선 및 원의 성분은 [x, y, l] 과 [x, y, T]의 2 개의 3-D parameter space 에 누적되고, parameter space 상에서의 병합 분할 과정을 거쳐, element 가 형성된다. 추출된 element 들은, parameter space 상에서의 방향성 및 상호 위치 관계에 의한 조합 형태로서, 미리 기술되어진 자모 모델과 비교되어 인식된다. 본 방법의 특정은, 문자의 크기에 무관하고, 해석방법에 의해서는, 끊어진 element나 불필요한 element 등의 왜곡된 element 들의 처리가 가능한 점, 4 차원 parameter space를 두개의 3 차원 parameter space로 분리, 처리시간과 기억용량의 절약을 기한점 등을 들 수 있다.

최근 보다 안전하고 효율적인 해상운송시스템을 위한 해결책으로 자율운항선박의 개발 및 운용에 대한 논의가 활발히 진행되고 있다. 자율운항기술은 해양사고 방지, 선박의 연비 증진, 비용 절감 등 긍정적인 측면과 함께 선원의 일자리 감소, 업무의 변화, 보안문제 등 부정적인 측면도 상존하고 있다. 향후 자율운항선박의 시대가 도래 하더라도 육상 센터에서의 제어가 이루어지게 되므로, 육상 운항사의 상황인식과 같이 새로운 인적요인 이슈가 존재할 것으로 예측된다. 본 논문에서는 자율운항선박의 개발 및 운용과정에 고려해야 할 주요 인적요인 이슈를 고찰하고, 육상 센터의 제어에 따라 예상되는 육상 운항사의 의사결정 및 업무수행에 영향을 미치는 요소에 대한 식별과 영향 요소의 평가를 위한 인적 신뢰성 분석 방안을 제시하였다.

This paper presents a Finite Element Method (FEM) application to thermal study of natural three layers of human dermal parts of varying properties. This paper carries out investigation of temperature distributions in these layers namely epidermis, dermis and under lying tissue layer. It is assumed that the outer skin is exposed to atmosphere and the loss of heat due to convection, radiation and evaporation of water have also been taken into account. The computations are carried out for one dimensional unsteady state case and the shape functions in dermal parts have been considered to be quadratic. A Finite Element scheme that uses the Crank-Nicolson method is used to solve the problem and the results computed have been exhibited graphically.
