  • 오픈소스 드론 펌웨어는 많은 민간 회사의 드론 OS의 기반이 되는 등 그 활용처가 매우 넓으며, 오픈소스 드론 커뮤니티가 활성화됨에 따라 드론 펌웨어에 대한 일반인들의 접근성 또한 높아졌다. 반면, 오픈소스 드론의 뛰어난 접근성에 반비례하여 취약점에 대한 분석이 미비하다. 이에 본 논문에서는 오픈소스 드론의 동적 분석을 위해 SITL과 HITL 시뮬레이션 환경을 구축하였으며, 구축된 환경을 활용하여 운용상 발생 가능한 제어권 획득 취약점을 연구하였다. 그 결과 드론의 펌웨어를 수정하여 다중 접속 및 제어권 획득을 성공하였으며, 모뎀으로 통신하는 드론의 경우 펌웨어 수정 없이도 다중 접속 및 제어권 탈취가 가능함을 확인하였다.

  • This paper presents the results of a case study of a dispute for the damage of the right to sunshine between B and W Apartment Complex in the N city. Recently a number of disputes for the right to sunshine increase in urban areas because the residents' demand for pleasant residential environment is getting stronger. In particular, problems related to sunshine, which were not recognized during the construction, have come up to the surface over time as people's concern over residential environment is growing. According to a recent interpretation of the right to sunshine in urban areas, moreover, there have been a series of legal decisions starting that damage of the right to sunshine to neighboring apartments must be indemnified for even if the violating apartment was designed and constructed legitimately according to relevant construction laws applied when the building was constructed. Thus this study examined the effects and the scope of damage on the right to sunshine through a case study in order to provide basic materials necessary to rope with related civil affairs.

  • The Solar Space Environment Division of the Korean Society of Space Science (KSSS) has recently conducted a survey among the domestic researchers affiliated with academia, national research institutes, and for-profit institutes of how the data and models in their professional research field are produced, maintained, and utilized. The primary purpose of this survey is to increase the awareness and utilization of the space environment data and models as well as to promote constructive collaborations among the domestic and international researchers. The models and data surveyed are categorized into three sub-fields: the solar and interplanetary space, the (terrestrial) magnetosphere, and the ionosphere and upper atmosphere. The present paper reports the survey results in the "Magnetosphere" category. The survey shows that the domestically produced data in this category are far less than the data produced in other categories. This can be understood in part as follows: Magnetospheric research relies heavily on the in-situ observations but the development and operation of space-hardened satellites require a significant investment. Nevertheless, the recent publications show an increasing trend of research using the data from the ground stations and the recently launched domestic space missions. In the modeling front, there are first-principles physics models covering from the magnetospheric scale to the sub-ion scale and the models geared towards the space weather prediction. The detailed survey results can be accessed from the KSSS website (http://ksss.or.kr/).

  • The stabilization time of take-over refers to the time it takes for driving to stabilize after the take-over. Following a take-over request from an automated driving system, the driver must become aware of the road driving environment and perform manual driving, making it crucial to clearly understand the relationship between the driving environment and stabilization time of take-over. However, previous studies specifically focusing on stabilization time after take-over are rare, and research considering the driving environment is also lacking. To address this, our study conducted experiments using a driving simulator to observe take-over transitions. The results were analyzed using a liner mixed model to quantitatively identify the driving environment factors affecting the stabilization time of take-over. Additionally, coefficients for stabilization time based on each influencing factor were derived.

  • The right of hot pursuit is an exception to the general rule that a ship on the high seas is subject to the jurisdiction of the state whose flag she flies. The right of hot pursuit is provided in the United Nations Convention on the Law of the Sea. This paper discusses the requirements of the right of hot pursuit. The use of force should be avoided during hot pursuit. When force is unavoidable, that is not go beyond what is reasonable and necessary in the circumstances.
