우리 민법에 상속인이 민법 제1019조 제1항의 기간 내에 한정승인 또는 포기를 하지 아니한 때에는 단순승인을 한 것으로 본다고 하여 그동안 상속인들에게 지나치게 불리하다는 비판을 받아왔던 규정이 1998년 8월 27일 선고된 헌법재판소 결정(96헌가 22 등)에 의하여 헌법불합치결정을 받았다. 이에 따라 2002년 1월 14일 법률 제6591호로 공포 시행된 개정민법 제1019조 제3항으로 "민법 제1019조 제1항의 규정에 불구하고 상속인은 상속채무가 상속재산을 초과하는 사실을 중대한 과실 없이 제1항의 기간 내에 알지 못하고 단순승인을 한 경우에는 그 사실을 안 날부터 3월내에 한정승인을 할 수 있다."는 규정이 신설되었다. 그러나 민법 제1019조 제3항은 상속인들에게 구제의 길이 열리기는 하였으나 상속인의 보호가 제한적이고 상속인에게 한정승인만을 허용하고 상속포기의 선택을 제한하여 상속인의 승인 포기의 선택권행사에 문제가 있다고 본다. 따라서 이 논문에서는 상속의 승인과 포기에 관한 문제점을 검토해보고 상속인과 이해당사자들 간 모두에게 불리함이 없이 가장 공평하고 합리적인 개선방안을 제시하고자 한다.

우리나라는 Eureka-147 방식의 디지털 라디오를 이동 멀티미디어로 확장하기로 하고 지상파 DMB로 불리는 비디오규격을 개발하였다. 지상파 DMB의 국제표준화를 위해 우리나라가 2004년 3월에 시스템 개요와 필드 테스트 결과를 ITU-R에 기고함에 따라 ITU-R 내에서 본격적인 이동 멀티미디어 표준화 논의가 시작되었고 우리나라 지상파 DMB 외에 일본의 ISDB-T, 노키아의 DVB-H와 퀄컴의 FLO 등을 대상으로 이동 멀티미디어 시스템 표준으로 개발하게 되었다. 3년여에 걸쳐 각 국간의 첨예한 이해관계에 의한 의견충돌과 합의를 거쳐 표준안이 작성되었으며, 표준화 방식은 휴대수신용으로 한정하고 각 시스템들을 알파벳에 따른 멀티미디어 시스템으로 명명하였다. 우리나라 지상파 DMB는 유럽 진출을 염두에 두고 디지털 음성방식 A인 Eureka-147 과의 호환성을 강조하기 위해 멀티미디어 시스템 A로 이름을 붙이기로 하였다. 지난 4월에 열린 ITU-R SG 6 회의에서 이동 멀티미디어의 표준화를 최종적으로 결정되었고 이후 회원국의 동의회신 절차를 거쳐 2007년 12월에 지상파 DMB가 ITU에서 휴대이동방송 시스템 중 하나로서 승인되었다.

인터넷상에서 원격강의와 같은 스트림 서비스를 제공하고자 하는 경우 사용자의 접속 품질을 일정 수준 이상으로 보장하기 위한 기능이 필요하다. 이를 위해 서버의 자원을 효율적으로 사용하는 것뿐만 아니라 일정 수 이상의 접속 요청이 있는 경우에는 사용자 등급에 따라 접속 허용을 제어함으로써 한정된 서버자원을 효과적으로 사용자에게 할당할 수 잇도록 하는 것이 필요하다. 본 연구에서를 이를 위해 사용자 정보에 기반한 어플리케이션 레벨에서의 서버 접속 승인 알고리즘을 제안한다.

The International Maritime Organization (IMO) explicitly stipulates the required performance of satellite based radio-navigation systems available for navigational purposes. Until 2019, the IMO had only recognized systems that could be serviced globally for satellite based radio-navigation. However, India's regional navigation satellite system has been approved recently, and other regional navigation satellite systems have also been made available for maritime navigation. Thus far, the IMO has approved the use of a total of five satellite navigation systems, such as the GPS, GLONASS, Galileo, BeiDou, and NavIC. In Korea, in addition to the four satellite based radio-navigation systems that are used excluding NavIC, Japan's regional navigation satellite system that has not yet been approved can be received. Japan has requested the IMO to recognize the QZSS as a WWRNS to formalize its use for ocean navigations. Given that the service coverage of the QZSS is not limited to Japanese territorial waters and also includes Korean waters, the suitability analysis of the QZSS for domestic navigation is important for maritime safety. This study aims to analyze the suitability of using the QZSS for domestic navigation. Accordingly, this work explores the status and plans of the QZSS as well as the performance required by the IMO for recognition as a WWRNS. The methods and environmental conditions examined in this work are described, and the analyzed results are presented in terms of positioning accuracy and availability.

In this paper we proposed system parameter values of M-ary PPM/TH(Pulse Position Modulation/Time Hopping) ultra-wideband systems having data rate of 100 Mbps for the frequency band, which is allocated by Federal Communications Commission(FCC). We also analyzed performance of the proposed system in the AWGN channels. According to the results of performance analysis, It is observed that available pulse duration is very limitative for this system. In case of constant data rate, if M and the pulse repetition numbers are increased, then the system performance is improved and the user number is decreased.

Cosmic Infrared Background Experiment (CIBER)는 적외선 카메라 및 분광기를 NASA Sounding Rocket에 탑재, 발사하여 적외선우주배경복사를 관측하는 과제이다. CIBER1은 2006년 NASA의 공식 과제로 승인되어, 미국의 Caltech, 한국의 KASI, 일본의 ISAS/JAXA가 국제협력으로 진행되었으며, 2009년 2월 25일, 2010년 7월 10일, 그리고 2012년 2월 25일에 미국 화이트샌드 미사일 기지에서 NASA 사운딩 로켓에 의해 성공적으로 발사되어 우주관측에 성공하였다. CIBER2는 CIBER1 보다 약 10 배 이상의 성능을 가지는 적외선카메라로써 한국의 KASI는 CIBER2 개발에서 광학계 및 광기계부 개발, 전자부 개발에 참여하고 있다. CIBER2는 2012년에 개발을 시작하여 2013년과 2014년에 각각 발사될 예정이다.

This paper proposes an improvement to differentiate assessment procedure for projects in consideration of their environmental impact as a means to improve efficiency in environmental impact assessment ("EIA") procedure. The targets of analysis were limited to lower impact projects. The current EA system in Korea has already attempted to introduce separate proceedings for certain projects.Tangible results from these efforts, however, have been limited. Other countries have adopted a "screening" system to determine whether EIA is applicable to a particular project, and if so, what procedure will be used therein. Therefore, this study suggests the screening as the process wherein need for EIA is determined with respect to projects which have undergone Prior Environmental Review System(PERS) and which appear to have comparatively negligible environmental impact. In this case, EIA can be omitted and the developer can then draft a mitigation plan instead. This study found that exempting certain projects deemed as having low environmental impact can considerably shorten the duration required for both environmental assessment and consultation, thereby improving efficiency. Other expected effects from the adoption of this screening include reduction in delays in project execution due to environmental assessments and reduced red tape through the provision of increased autonomy to developers and the approving authorities.

The purpose of this study is to raise the drinking rate of Arisu, the tap water in Seoul, and to propose new solution for continuous water quality management and raising awareness. The research scope was limited to point-of-use water treatment system, and based on the this contents I proceed this study how this will help to increase direct drinking rate of Arisu. Through research, Korea has provided users with the ability to filter contaminated tap water simply as water to be rinsed through water purification. Therefore, it was predicted that it would be difficult to improve tap water as drinking water. With this study, I expect that the strength of point-of-use system and the reliability of tap water quality will be raised and hope various product will be developed to improve the perception as drinking water and I also expect that this can be applied to whole country even further in the scope of Seoul city.

Load transfer experiments have been carried out to evaluate the performance of the anchorage and it has been stated that the specimens were manufactured and tested according to ETAG 013. On the other hand, the amount of spiral reinforcement and auxiliary reinforcement exceeded the amount specified in ETAG 013. In this study, the load transfer test method and the criteria specified in ETAG 013 were considered and the PT anchorage system was applied to manufacture specimens with high strength concrete and a high tensile prestressing strand. A load transfer test according to ETAG 013 was performed to evaluate the performance of the circular anchorage. As a result, it was confirmed that ETAG 013 is a very strict specification that does not satisfy the performance of an anchorage unless the specimens of an appropriate size and spiral reinforcement are used. To assess the stability of the specimens, increasing the size of the specimen by 15%, rather than increasing the amount of auxiliary reinforcement, is considered to be the correct method in accordance with ETAG 013.

Rapid growth of internet utilization consequences in an expansion of individual's social networks via SNS. Recently, Facebook has added six different emotion buttons reflecting suggestions claiming that "Like" button is limited, and thus must be improved. Regarding to how well newly updated six different emotion buttons were utilized, a survey that inquires the usefulness and usability of buttons for further improvement in service was conducted to 35 Facebook users of 20's and 30's, the most active ages with frequent usages. As a result, users responded with negative attitudes considering expression of six different emotions in Facebook, and exhibited less frequent usages of the service. According to respondents, the emotion expression service would lead better approachability if Facebook suggests simpler emotion expression, for example, two emotion buttons rather than current six buttons.
