The Korean supreme court said that Mrs Kim who was in a persistent vegetative state had a right to die if she had a presumed will or assumption of dying against Severance hospital in 2009. Presumed would be vague and can not be subjective to conjecture though, the court had a developed trial on the case. I recommend the higher valued notion such as the 'right to decide on the life extension' is more logical than assumptive will. To achieve this recommendation, I will search right to life, right to decision, human dignity and find the good relationship between them. In conclusion, I will announce that if PVS patients without advanced directives aren't able to express their will and no one could not assume their right to die in spite of meaningless life extension. So only the due and strict procedure about the extinction of meaningless PVS patients will allow them to sacrifice themselves or remove life extension ventilators. Also active euthanasia would be possible under the strict procedure of making advanced directives and the act of helping active euthanasia additionally, the crime of abetting suicide would not be executed in the legal scope.

The under-drive brake piston is an essential part in the automatic transmissions of automobiles. This component is manufactured by forging after blanking from S55C plate with a thickness of 6mm. It is difficult to design the plate forging process using a thick plate approach since there will be limited material flow as well as large press loads. Furthermore, the under-drive brake piston has a complex shape with a right angle step, which often results in die unfill and abrupt increase in press load. To overcome these obstacles, a separate die for filling material sufficiently to the corner of the right angle step is proposed. However, this approach induces an uncontrolled workpiece surface between the dies, resulting in flash. This excess flash degrades the tool life in the final machining after cold forging as well as increases the cycle time to obtain the net-shape of the part. In the current study, we propose an optimum process design using a conventional die shaped with the benefit of finite element analysis. This approach enhanced the process efficiency without sacrificing the dimensional accuracy in the forged part. As the result, the optimum plate forging process was done with a two stage die, which reduces weight of by 6% compared with previous process for the under-drive brake piston.

The Law has intervened to define rare circumstances in which a person should choose continuing life in United States. On the one hand, the law has traditionally acted to preservelife and to respect the sanctity of life. On the other hand, one's control over one's own body, and the right to determine what kind of medical care one will receive, is equally well respected and historically grounded. The competent patients have the right to forgo life-sustaining treatment, courts in United States have left many unanswered questions about the nature of that right. The right to choose to forgo life-sustaining treatment is a manifestation of a patient's autonomy interest. In United States, The Karen Quilan case gave rise to legislative activity in the host of state capitals, and several states had adopted statutes that formally recognized some forms of written directives describing some circumstances in which certain kinds of medical care could be terminated. These statues were sometimes dominated 'living will' acts, sometimes 'right to die' acts and ocasionally 'natural death' acts. Today virtually every state has produced a living will statue. In Korea, courts do not permit a terminally ill person to withhold or withdraw life-sustaining treatment. Living wills apply in case of terminal illness owing to a defect in legislation. Now In Korea, these lively dispute of legal policy on the preconditions and concrete procedure of living will act and natural death act. Through the legislation of living will act and natural death act, we should prepare some circumstances to respect patient's autonomy on the right to die. We should frame the cultural standard to make a decision of forgoing life-sustainin1g treatment under the discreet procedure.

In this paper, the method of improving the flatness and perpendicularity for a corner fixing bracket of the large display frame is studied through experiments. Three specimens were tested, one specimen not subjected to bending line before bending, and two specimens with a straight groove with 0.2 mm and 0.5 mm depth. Experimental results show that the flatness of bracket becomes worse with deeper depth. When there is no straight groove, the perpendicularity becomes worse. For the flatness correction, a restriking process was added. The twist of bracket was corrected by performing the restriking with a curvature larger than the twist amount in the direction opposite to the deformed direction. We also found that the perpendicularity is maintained regardless of the amount of curvature with the restriking process.

To meet the need for trained work force from the industries, industry-oriented education for students majoring in die & mold in university level is required. If the new university graduates with creativity and high technology could be put right into the work places without training at the work sites, that will lead to remove the wasting factor in education and reinforce the competitiveness of Korea's technology power. Industries would be satisfied with the trained workforce from universities and the rate of employment will be increased. To meet the needs from industries and universities, die & mold design engineering curriculum tailored for industries is developed.

Uneven clearances in the left and right sides of a press die cause deformation of the punch in precision shearing process. This deformation results from the compression stress and bending moment from shearing force in vertical direction and from the side force in horizontal direction acting to the punch, In this study the behavior of punch deformation is investigated in order to clarify the deformation state of the punch by using strain gauge deformation to shearing force side force bending moment radius of curvature and shear plane of the punch. Also we presented the calculation method of deformation size for the punch.

The quality of the sheared surface affects the stretch flangeability of steel sheet. The quality of sheared surface is influenced by several process factors such as die clearance, shape of cutting edge, use of counter punch, and shear. In this paper, the influence of these shearing process factors on the stretch flangeability of the HSS (DP980) was analyzed through a shearing and a stretch flangeability test. When the die clearance was 10%, the effect of these shearing process factors on the stretch flangeability was the greatest, and the use of an acute angle blade was found to be more advantageous in the stretch flangeability than a right angle blade. It was found that the stretch flangeability was improved when active bending was applied during shearing.

"Aid in Dying" means that when a decision-making patient suffers from an incurable disease, a drug that can speed up death is prescribed by a doctor and used to lead to death. Since the suspension of life-sustaining treatment was institutionalized based on human dignity and patient autonomy, the question of whether assisted death can be legally justified in relation to the right to receive medical help to shorten one's life to die with dignity has recently been actively discussed. In Korea, since the suspension of life-sustaining treatment was institutionalized by the enactment of the Life-sustaining Treatment Decision Act in 2016, an amendment to the Life-sustaining Treatment Act was recently proposed to legalize Aid in Dying. The global trend is that human "Right to Die" is discussed in the division of life and death, from the suspension of life-sustaining treatment to assisted death, and again in the order of euthanasia. In this paper, we started discussing dignified death and institutionalized patients' right to self-determination, looked at the controversy in the United States, which legislated assisted death in many states since the 2000s, and analyzed the main contents of California's End of Life Option Act and the data after enforcement. The strict requirements for Aid in Dying, such as voluntary confirmation of patients' intentions and doctors' obligation to provide information, and the results of California's Aid in dying system, composed of relatively diverse races, were reviewed.
