Recently, the government tends to address the health policy as an economic logic. However, health policy must be priority to national health right than economic logic. Thus, in this paper analyzes the problems of telemedicine for telemedicine that are at issue in South Korea, based on this, and presents reasonable health policy directions for telemedicine. To amend the law and legislation the health policy and law, analyze the rationality, feasibility of law and sufficient review should be implemented. Comparing to the foreign which introduced telemedicine earlier, discussion on telemedicine in South Korea remains a long way to go and it is now beginning step. Therefore, it should not forget that the health policy of the government with crass insensitivity can bring great disaster. Above all, to the health care, the sufficient review and social consensus which can reduce the side-effects are priority.

This paper considers a robust adaptive stabilization problem for a class of uncertain nonlinear systems which include an unknown virtual control coefficient, an unknown constant parameter, and a time-varying disturbance whose bound is unknown, We propose a new estimator for an un-known virtual control coefficient and present a robust adaptive backstepping design procedure which results in a smooth state feedback control law, a new two-dimensional parameter update law, and a $C^1$ Lyapunov function which is positive definite and proper.

The development of the biomedical science and technology has extended an argument about a status in constitutional law of unborn human life and a protection of the potential human life to that of an embryo and a gamete beyond a fetus. This argument has been focused on whether we should provide unborn or potential human life with human dignity and the right to life that are guaranteed by the constitutional law altogether or separately. If the right to life is given to unborn or potential human life, on what grounds can we restrict this right. Those who argue for the unity of the right to life with human dignity and the inseparability of those two claims that the right to life in itself should be guaranteed absolutely. According to the constitutional law, however, any constitutional right of the human person within the protection of essential part of the right can be compared with each other and restricted with some valid reasons from the legal perspective. This measure is unavoidable in reality because one right can come into conflict with another right frequently. Since fetus and embryo are in a process of developing into the human person, it is difficult to think that they are the same with the human person. For that reason, it is hard to consider that the right to life of fetus or embryo is the same with that of the human person. However, since a fetus has a special status as a potential human person, and an embryo also has a special value as a potential fetus upon an implantation, the right to life of fetus or embryo should be judged differently according to the stage of their development. A study on a constitutional status and protection of a fetus and an embryo is essential because unborn or potential human life is the origin of human person. Therefore, we have to make much account of their right to life and seek the legal respect for their inherent value.

Attitude control law design for spacecraft large angle maneuvers is investigated in this paper. The feedback linearization technique is applied to the design of a nonlinear tracking control law. The output function to be tracked is the quaternion attitude parameter. The designed control law turns out to be a combination of attitude and attitude rate tracking commands. The attitude-only output function, therefore, leads to a stable closed-loop system following the given reference trajectory. The principal advantage of the proposed method is that it is relatively easy to produce reference trajectories and associated controller.

This study deals with arbitration award via modern technical means; because e-Arbitration is deemed to be one of the most important substitute means for the settlement of disputes arising from electronic transactions. This type of arbitration is characterized by fast settlement of disputes, as well as fast enforcement of awards rendered thereon. The researcher seeks to indicate the content of the award, the conditions for rendering it, and to analyze the legal provisions related to its legal basis in the Saudi Law of Arbitration. This study shows that an arbitration award, rendered via modern technical means has a number of advantages, such as fast settlement, less cost, and keeping pace with modern technology, which is an aim of Saudi Arabia Vision 2030. The study also points out certain problems facing arbitration via technical means; however, the most important of which is the insufficiency of some legal rules associated with traditional arbitration, as contained in the Saudi Law of Arbitrator, which are incompatible with or applicable to an arbitration award which is rendered via modern means.

Face gear transmission is widely used in aerospace shunt-confluence transmission system. Tooth wear is one of the main factors affecting its bearing transmission performance. Furthermore, the installation errors of face gear are inevitable. In order to study the wear mechanism of face gear tooth surface with installation errors, based on tooth contact analysis numerical method and Archard wear theory, the UMESHMOTION subroutine in ABAQUS is developed.Combining with Arbitrary Lagrangian-Eulerian adaptive mesh technology, the finite element mesh wear model of abraded face gear pair is established.The preprocessing conditions are set to generate the inp files.Then,the inp files for each corner are imported and batch processed in ABAQUS.The loading tooth contact problem at each rotation angle is solved and the load distribution coefficient among gear tooth, tooth root bending stress, tooth surface contact stress and loaded transmission error are obtained. Results show that the tooth root wear is the most serious and the wear at the pitch cone is close to 0.The wear law of tooth surface along tooth width direction is convex parabola and the wear law along tooth height direction is concave parabola.

The problem of optimal stochastic GA control of the system with uncertain parameters and unsure noise covariates is studied. First, without knowing the explicit form of the dynamic system, the open-loop determinism problem with path optimization is solved. Next, Gaussian linear quadratic controllers (LQG) are designed for linear systems that depend on the nominal path. A robust genetic neural network (NN) fuzzy controller is synthesized, which consists of a Kalman filter and an optimal controller to assure the asymptotic stability of the discrete control system. A simulation is performed to prove the suitability and performance of the recommended algorithm. The results indicated that the recommended method is a feasible method to improve the performance of active tuned mass damper (ATMD) shear buildings under random earthquake disturbances.

The Korean government has recently invigorated the activities of public diplomacy. It is based on the Public Diplomacy Act enacted in 2016. However, there is a widespread concern that it was belatedly enacted and showed necessity to a revision. We believe that this paper contains three contributions which were not sufficiently addressed before. First, we identify the current state of public diplomacy-related legislation in Korea. Second, we argue the necessity to critically review the legal adequacy of Public Diplomacy Act with a consideration of rapidly changing external environment. Lastly, we propose several ways of revision for the future development of public diplomacy in Korea. When revising the Act, it is necessary to make clear a legal connection between the general law and the special law as in the case of the Korea Foundation Act and the Public Diplomacy Act. In this regard, it is worth examining the relationship between the Framework Act on International Development Cooperation and related norms. In addition, the role of the private sector and subnational governments should be expanded. For this purpose, a method and level of cooperation with the private sector should be clearly defined.
