우리에게 자유는 너무나 당연한 것으로 여겨진다. 그럼에도 불구하고 자유롭지 못한 현실을 경험하고선 당황한다. 우리는 자유로워야 하며, 자유로울 수밖에 없는 존재인데, 왜 그렇지 않은 현실을 느끼게 되는 것일까? 본고는 이와 같은 생각이 인식론적 사유에서 기인한다고 보면서, 사르트르의 자유 또한 이와 같은 사유 위에서 잘못 평가되고 있음에 주목한다. 특히 사르트르에 대한 이와 같은 평가는 메를로-퐁티 연구자들에 의한 것으로서, 그들에 따르면 '메를로-퐁티가 사르트르를 전통적인 인식론적 사유를 기반으로 한 자유론자라고 비판'하고 있다는 것이다. 본고의 목적은 이와 같은 평가의 문제점을 밝히고 사르트르의 자유가 '메를로-퐁티가 비판하는 절대적 자유'가 아님을 보여주는데 있다. 이를 위해 먼저 메를로-퐁티가 비판하는 절대적 자유가 어떤 것인지 살펴볼 필요가 있는데, 여기서 우리는 이 '절대적 자유'를 인식론적 이원론에 따른 이성의 절대적 자유로 파악한다. 이성의 절대적 자유는 추상적이고 이념적 자유인 까닭에, 메를로-퐁티에 따르면 존재하지 않는 자유로 간주된다. 이와 같은 논점을 전제로 하여 우리가 확인하는 것은 사르트르의 절대적 자유가 인식론적이 아닌 존재론적으로 파악되어야한다는 점이다. 사르트르는 이 문제를 즉자존재와 대자존재와의 관계를 통해 밝혀 보이고 있다. 마지막 장에서 우리는 메를로-퐁티의 조건지어진 자유에 대해 논하면서, 그것이 상황의 자유이자 선택의 자유임을 보여줄 것이다. 이때 우리가 확인하게 될 것은 사르트르가 말하고자 하는 자유 또한 절대적 이성의 자유가 아니고, 상황 속에서 우리가 선택하게 되는 자유라는 점이다. 사르트르는 대자존재의 사실성이 우리를 상황 속에 처하게 하고, 이 상황이 나의 자유의 토대가 된다고 말하고 있다. 따라서 대자존재의 무는 절대적 이성의 다른 모습이 아니라, 부정의 상태로만 존재하는 대자존재의 존재방식을 드러내고 있다는 사실을 주지해야 한다.

Korean religionist have actively participated in the movements of national security and peace, human rights and dignity, freedom and equal rights, and other social issues. Recently, either progressive or conservative religionists have strongly shown their different approaches in solving social issues, i.e., national security and peace in connection of 'national security law.' A few religious leaders' public views have been misused by some politicians. It is important for both the religionists and journalists in religious newspapers how to bring a harmonious resolution among the people who are either in conservatism or in progressivism. Social participation of religionists is both to respond to the timely situation of civil society and to realize freedom, equality, and peace to the society. Although the principle of the separation of religion and state was established to secure both the right of politics and the freedom of beliefs, political groups have either utilized or suppressed religions. Some politicians have also wrongly applied separation of religion and state by excluding religious aspects in public schools. Religionists and journalists of the religious newspapers should not provide one-sided prejudice but to provide objective information and its righteous analysis to guide people in the right direction to solve social problems. Also, religious newspapers should open a field of discussion how to resolve some issues between the 'national security law' and freedom.

Navigating a large 3D virtual environment using a generic haptic device can be challenging since the haptic device is usually bounded by its own physical workspace. On the other hand, mouse interaction easily handles the situation with a clutching mechanism-simply lifting the mouse and repositioning its location in the physical space. Since the haptic device is used for both input and output at the same time, in many cases, its freedom needs to be limited in order to accommodate such a situation. In this paper, we propose a new mechanism called Z-Clutching for 3D navigation of a virtual environment by using only the haptic device without any interruption or sacrifice in the given degrees of freedom of the device's handle. We define the clutching state which is set by pulling the haptic handle back into space. It acts similarly to lifting the mouse off the desk. In this way, the user naturally feels the haptic feedback based on the depth (z-direction), while manipulating the haptic device and moving the view as desired. We conducted a user study to evaluate the proposed interaction technique, and the results are promising in terms of the usefulness of the proposed mechanism.

STATEMENT OF PROBLEM. Implant drivers are getting popular in clinical dentistry. Unlike to implant systems with external hex connection, implant drivers directly engage the implant/abutment interface. The deformation of the implant/abutment interface can be introduced while placing an implant with its implant driver in clinical situations. PURPOSE. This study evaluated the change of rotational freedom between an implant and its abutment after application of different insertion torques. MATERIAL AND METHODS. Three kinds of internal connection implants were utilized for the current study($4.5{\times}12\;mm$ Xive, $4.3{\times}11.5\;mm$ Inplant Magicgrip, $4.3{\times}12\;mm$ Implantium MF). An EstheticBase, a 2-piece top, a Dual abutment was used for its corresponding implant system. The rotational freedom between an implant and its abutment were measured before and after applying 45, 100 Ncm insertion torque. Repeated measures ANOVA was used for statistical analysis. RESULTS. Under 45 Ncm insertion torque, the rotational freedom between an implant and its abutment was significantly increased in Xive(P = .003). However, no significant change was noted in Inplant Magicgrip and Implantium MF. Under 100 Ncm torque, both in Xive(P = .0005) and Implatium MF(P = .03) resulted in significantly increased rotational freedom between the implant and its abutment. DISCUSSION. The design of the implant/implant driver interface effectively prevented the deformation of implant/abutment interface. Little change was noted in the rotational freedom between an implant and its abutment, even though the insertion torque was far beyond clinical application. CONCLUSIONS. The implant/abutment joint of internally connecting implants were quite stable under insertion torque in clinical situation.

In human-mechanical cooperative systems, a significant issue is to improve the control performance and the maneuvering feeling of human operation. However, since it is not easy to evaluate the feeling of operators numerically, control engineers design controllers only through experience. Thus, in this paper, a new evaluation method for control performance of human-mechanical cooperative system is proposed based on the reserge waveform. Various distortions of waveform represent deteriorations of control performance and maneuvering feeling. In some cases, since there is a tradeoff between the control performance and the maneuvering feeling, it is difficult to compensate for both of them by usual feedback controllers. To overcome this situation, the two degrees of freedom control system is applied to human-mechanical cooperative system. Some numerical simulation results for an electric power steering system are shown to confirm the effectiveness of proposed control design method.

The Theo Jansen mechanism using 1 degree of freedom is special system of walking robot. The trajectory made by the point of ground position is similar to other walking robot using many degrees of freedom. Because of diversity of design parameter of the Jansen mechanism, it makes a lot of trajectory and takes possibilities of optimization. However this research doesn't focus on the optimization of trajectory, but it focused on comprehensive design of the robot using well-known trajectory and line tracer logic to go fast and accurate along the line. The logic to follow a line has many kinds of possibility of algorithm. To eliminate uncertainty about recognizing a line, I divide the case of line following situation and make optimized logic.

Background : There have been a variety of healthcare systems related to CAM practitioners developed in each country. However, the European cases have not been widely introduced in Korea so far. In the case of Germany, CAM practices have been developed in the frame of "Heilpraktiker" system. Objectives : The objectives of this study were to review the historical development and current situation of German Heilpraktiker system and its conflicting relationship with Western medical doctors, in order to utilize it as basic data for the conflict resolution between Western- and KM doctors in Korea. Methods : The historical development, current regulations and education system of Heilpraktiker were assessed. Research articles, reports, government publications and websites dealing with this issue were searched for and analyzed. Results : Heilpraktiker system was developed within German historical and cultural situation where naturopathic traditions were reilluminated in connection with modernization process of the state under the influence of romanticism formulating German nationalism. Between the concept of "Kurierverbot"(prohibition on medical treatment by non-physicians) and "Kurierfreiheit"(freedom of medical treatment), Heilpraktiker achieved a limited but legitimated right to conduct non-biomedical treatments from the state in the process of the formulation of modern German medical system. In this process, the conflicts between medical doctors and heilpraktikers have been also growing up to now. Conclusions : Heilpraktiker system, officially recognized with the legislation of Heilpraktiker law in 1939, stands at a crossroads between the continual development through strengthening its professionality, and abolition of the system due to its lack of quality control and medical evidence mostly argued by Western medical doctors, which has considerable implications for Korean situations in terms of the conflicting relationship between KM- and Western medical doctors. In this regard, it is necessary to discuss the debates on the concept "Kurierfreiheit"(freedom of medical treatment) developed within German tradition of medical pluralism.
