In Korea, there is no clear regulation about right of way (ROW) for personal mobility device (PMD). So it is now illegal to use PMD in a space other than roadway. PMD has an advantage of being able to travel a long distance to move on foot with a relatively high speed, so it seems to spread widely in the near future. In this study, we'd like to establish the permission criteria for PMD in sidewalk, with the performance factors of the PMD. We review the cases of ROW of PMD in some foreign countries, and the performance standards for similar products that are currently allowed to use in the sidewalk or used in the sidewalk. Based on the maintenance standards for the sidewalk, we establish criteria to select the PMD moving means that can be used in sidewalk.

Recently, many nations said "yes" to human embryonic stem cell research, signing an executive order to permit funding for the research in the mame of achieving health and life of humankind. Human Embryo Research is permitted by our Bioethics & Biosafety Act. But, illegal research cannot be divorced from civil liability since it requires the destruction of eggs of fertilized eggs and personal rights of embryo-creator. After all, though we allow to do research embryo, we should control the capacity of abuse of embryo research for embryo-creator. If research violate the law(Bioethics & Biosafety Act or Civil Law, etc), it comes to a delict by pecuniary loss and non-pecuniary loss. When it comes to pecuniary loss, Human Embryo is not body but special property. Supreme Court maintained a stance that mental suffering is generally deemed as compensable for damages for the loss of property where a person's property right is invaded by a tort or non-performance of obligation. Thus, where mental suffering occurs, which cannot be compensated by recovery of property losses, the situation must be a special circumstance and the injured could claim consolation money for such losses only if the offender knew or would have known of such special circumstances(Supreme Court Decision 96Da31574 delivered on Nov, 26, 1996, etc.). That is to say, Supreme Court regards mental suffering through person's property right invaded by a tort as damages that have arisen through special circumstances. According to Civil law article 393 (2), the injured could claim consolation money for such losses only if only if the offender had foreseen or could have foreseen such circumstances. Also our court will solve through damages for non-pecuniary loss by complementary function of consolation money in that pecuniary loss could be difficult to valuate.

This study investigates channel stabilities with groynes by developing the assessment of it and applying a 2-dimensional numerical model, which simulates flow and sediment transport with various flows in the channel. Evaluation inventories are composed of five items, which are width to depth ratio, sinuosity, bed slopes, velocities in the flow flied, Shields number with discharges and geomorphic characteristics in the study reach. The channel stability is evaluated by applying the evaluation indicators to the channel with and without groynes in the study reach between Dalseong-weir and Gangjeonggoryeong-weir in the Nakdong river. Width to depth ratio, sinuosity, and bed slopes, which are index of river characteristics, little affect the channel stability. However, velocities in the flow flied, and Shields number, which is dimensionless tractive, near the banks of the channel strongly affect the stability. The evaluation values of the stability in the channel on the left and right banks decrease as the number of groynes increase in both the left and right banks, which means that the bank stability increases with the groynes.

In Korea, the importance of walking has not been stood out in relief because of the rapid increase of a car on a drastic economic growth in the past half a century. Walking has failed to be recognized as a traffic measure or one of basic human rights. Therefore this study brings up problems of weakened walking right from increase of cars and examines reinforcing policies for walking right of advanced countries. And this study presents institutional devices for introducing walking safety measures of advanced countries reflecting pedestrian satisfaction and opinions about walking right. The results of this study are, First, pedestrians' walking liberty is guaranteed, Second, how to repair walking environment is searched and practical measures are analyzed to find out what is applicable to Korea, can reduce pedestrian accidents and is wanted by pedestrians using GAP analysis and Structural Equation. Third, basic data for upcoming selection of policies are presented by analyzing pedestrian satisfaction assuming that selected measures are operated.

Barrier-free films enhance accessibility to audiovisual image contents by providing specific information on screen and through sound so that people with vision or hearing loss can receive the same amount of information as those without disabilities and immerse themselves in the audiovisual images. This study pays attention to barrier-free audiovisual contents in relation to the cultural civil rights of people with vision or hearing loss in South Korea. While institutional efforts have been made in the 2010s to improve the access to audiovisual media of people with vision or hearing loss, the goal of enabling people with vision or hearing loss to fully enjoy all audiovisual contents at a level equal to the non-disabled has not yet been realized. Amid the lingering conflict between disabled groups and multiplexes that has lasted years, the global video streaming service Netflix has aggressively threatened the dominance of local multiplexes with the launch of its Korean service. As Netflix, which is subject to U.S. regulations guaranteeing the rights of people with vision or hearing loss, has produced original dramas and movies involving Korean production teams, the cultural civil rights discourse of the disabled has transitioned to the issue of the rights of cultural consumers crossing national borders in the era of globalization. Changes in the media environment raise the issue of civil rights guarantees in which disabled people enjoy the right to simultaneously watch movies and comment on movies by participating in a common discourse, equally with non-disabled people. The "right to be part of the audience for Korean cinema" for Korean deaf people, which has long been neglected, should also be considered as a cultural civil right that crosses the boundaries of language, nation and disabilities. This essay examines the current issues surrounding the right to cultural entertainment of people with vision or hearing loss in South Korea in conjunction with the contemporary trend of rapid changes in the media environment and the global spread of the movement for cultural civil rights of people with disabilities, and suggests the need for visual culture studies to take a serious step toward disability studies.

By means of finite element numerical simulation and pseudo-static method, the shallow-buried bilateral bias twin-tube tunnel subject to horizontal and vertical seismic forces are researched. The research includes rupture angles, the failure mode of the tunnel and the distribution of surrounding rock relaxation pressure. And the analytical solution for surrounding rock relaxation pressure is derived. For such tunnels, their surrounding rock has sliding rupture planes that generally follow a "W" shape. The failure area is determined by the rupture angles. Research shows that for shallow-buried bilateral bias twin-tube tunnel under the action of seismic force, the load effect on the tunnel structure shall be studied based on the relaxation pressure induced by surrounding rock failure. The rupture angles between the left tube and the right tube are independent of the surface slope. For tunnels with surrounding rock of Grade IV, V and VI, which is of poor quality, the recommended reinforcement range for the rupture angles is provided when the seismic fortification intensity is VI, VII, VIII and IX respectively. This study is expected to provide theoretical support regarding the ground reinforcement range for the shallow-buried bilateral bias twin-tube tunnel under seismic force.

To evaluate the engineering properties of soil, the laboratory test always is carried out using samples obtained from the field. There are many studies to estimate the effect of sampling disturbance. The objective of this study appraises the disturbance using the shear wave velocity. The new shelby tube which three transducers are installed every 20cm interval is used. To laboratory tests, the large-scale consolidometer (calibration chamber) is used. During 1cm penetration, the shear wave velocity is measured by every transducer. The initial sampling disturbance is assessed through the velocity difference from bottom to right upside transducer. After finishing the sampling, the velocity is still measured every time to assess the soil disturbance in shelby tube itself. Through the measured velocity, the effect of disturbance is appraised. This study suggests that the sampling disturbance of shelby tube is effectively evaluated using shear wave velocity.

The intake towers of Buyeo W.T.P. in Keum river have being suffered from the sedimentation problems since the beginning of the operation. Impellers of the intake pumps have to the frequently changed due to the serious surface erosion. Thousands tons of sands are entrapped in the intake towers and equalization chambers of W.T.P. every year. Site surveying and numerical analysis were carried out to suggest an appropriate solution by understanding the general sedimentation regime of Keum river and causes of the sedimentation in the intake towers. Origin of the sediment could be found by the desk and site inspections. The validity of the used numerical models was examined by comparisons between the calculated bydraulic values and the measured ones during the specific periods. The design flow rate for the prediction of the future sedimentation regime of the rever was studied. The efficiency of the sediment control measures was also examined with the verified numerical models. Finally, it was found that the best solution could be a combination of three sediment control measures; increase the clearance between river bed and inlet, construct jetties at 2 kilometers upstream from the intake towers, and put vanes at the right side of the intake towers.

In current law, the premium medical treatment system gives patients the right of choice between normal medical treatment service and premium medical treatment service. Only the doctors having a career more than a certain period of time fixed in the law are eligible for providing the premium medical treatment service. So, the premium medical treatment system is highly related to the patients' right to know and the right of self-determination. The system is also relevant to the so-called 'economic explanation' notion because patients should pay additional fee when they want to use this system. Meanwhile, the situation as follows is problematic as to this system. Although a patient applied for using the premium medical treatment system and the patient also chose his or her own doctor specifically, another doctor who was not selected as premium doctor could make a medical accident. Then, is the another doctor liable for damages because the accident was a medical malpractice or a breach of medical contract? In this study, we are going to examine the problems related with the premium medical treatment system. First, we examine the current law related to the system. Second, we look into the economic explanation duty and its application to the premium medical treatment system. Finally, we examine a real judgment case about a medical practice against the premium medical treatment system and we propose our solution to this case.

This thesis describes collision avoidance using fuzzy logic based on "Right of way" rules of ICAO and FAA and pilot's experiences for Unmanned Aerial Vehicle(UAV). To apply the rules, we designed fuzzy logic based collision avoidance system. And we also designed decision logic for enable condition of collision avoidance system. Decision logic have three kinds of core key, i.e. Relative Range, Time of CPA(Closest Point of Approach) and Distance at CPA. Application of decision logic made a possible to avoid NMAC(Near Mid-Air Collision) and it has been verified through several simulations. To conclude, we proposed the method to carry out "See and Avoid" ability on UAVs, which is capability to mingle with manned aircraft in civil airspace.
