The best value proposition for the customers of satellite-DMB (hereinafter referred to as the "S-DMB") business in an environment of fierce competition shall be securing the best killer contents and distribute them in reasonable price as a mobile contents platform provider. In an era of merging the broadcasting with the communication, although many new players tapping into the market with state-of-the-art media such as digital convergence, the key to success in the market is dependent on whether the respective digital contents providers retain competitive digital contents which suit the taste of customers. Considering such market conditions, the purpose of this study is to look over the management examples of Korean S-DMB providers which is carrying out business in digital multi-media market and opening up the market, and to analyze the management strategies of domestic S-DMB companies to be the champion in the market.

Reproductive biotechnology has developed rapidly and is now able to overcome many birth difficulties due to infertility or the transmission of genetic diseases. Here we introduce the next generation of assisted reproductive technologies (ART), such as mitochondrial replacement technique (MRT) or genetic correction in eggs with micromanipulation. Further, we suggest that the transmission of genetic information from somatic cells to subsequent generations without gametes should be useful for people who suffer from infertility or genetic diseases. Pluripotent stem cells (PSCs) can be converted into germ cells such as sperm or oocytes in the laboratory. Notably, germ cells derived from nuclear transfer embryonic stem cells (NT-ESCs) or induced pluripotent stem cells (iPSCs) inherit the full parental genome. The most important issue in this technique is the generation of a haploid chromosome from diploid somatic cells. We hereby examine current science and limitations underpinning these important developments and provide recommendations for moving forward.

For over 50 years, boron neutron capture therapy (BNCT) has been steadily developed for treating various cancers. This is a non-invasive, selective, and targeted radiotherapy wherein boron-rich molecules accumulate at the tumor site. Liposomal vesicles have become a popular and effective drug delivery system for BNCT, with strategies including surface decoration, bilayer integration, and hydrophilic core encapsulation. This review highlights the state-of-the-art uses of liposomes in BNCT and elucidates a new perspective where BNCT can be used with radiotracer guidance in all-in-one delivery systems.

Because hyperspectral imaging provides detailed spectral information across a broad range of wavelengths, it can be utilized in numerous applications, including environmental monitoring, food quality inspection, medical diagnosis, material identification, art authentication, and crime scene analysis. However, hyperspectral images often contain various types of distortions due to the environmental conditions during image acquisition, which necessitates the proper removal of these distortions through a data preprocessing process. In this study, a preprocessing method was investigated to effectively correct the distortion caused by artificial light sources used in indoor hyperspectral imaging. For this purpose, a halogen-tungsten artificial light source was installed indoors, and hyperspectral images were acquired. The acquired images were then corrected for distortion using a preprocessing that does not require complex auxiliary equipment. After the corrections were made, the results were analyzed. According to the analysis, a statistical transformation technique using mean and standard deviation with reference to a reference signal was found to be the most effective in correcting distortions caused by artificial light sources.

This study presents a novel safe landing algorithm for urban drone deliveries. The rapid advancement of drone technology has given rise to various delivery services for everyday necessities and emergency relief efforts. However, the reliability of drone delivery technology is still insufficient for application in urban environments. The proposed approach uses the "landing angle control" method to allow the drone to land vertically and a rapidly exploring random tree-based collision avoidance algorithm to generate safe and efficient vertical landing paths for drones while avoiding common urban obstacles like trees, street lights, utility poles, and wires; these methods allow for precise and reliable urban drone delivery. We verified the approach within a Gazebo simulation operated through ROS using a six-degree-of-freedom drone model and sensors with similar specifications to actual models. The performance of the algorithms was tested in various scenarios by comparing it with that of stateof-the-art 3D path planning algorithms.

지금까지 '훈민정음'이 세종의 명을 받든 집현전 학사들에 의해 창제되었다는 견해가 일반적이었지만 본 논문에서는 신미(1403-1480)가 세종의 밀명을 받고 '훈민정음' 창제에 주도적인 역할을 하였음을 밝히고, 나아가 이와 관련 설화의 문화융합 콘텐츠의 가능성을 모색하고자 한다. 연구방법으로 특히 "세종실록", "문종실록", "한국불교전서" 등 문헌 중심으로 그 근거를 살펴보았다. 그 결과 첫째, 세종의 신미에 대한 절대적인 신임, 둘째, 신미가 범어에 능통하여 불경 해역에 탁월한 능력을 발휘한 점, 셋째, 세종이 금동아미타삼존불을 복천암에 시주하고, 신미에게 '국이세(國利世) 혜각존자(慧覺尊者)'라는 존호를 내린 점, 넷째, 신미의 불교를 통한 훈민정음의 교육과 보급의 서원, 다섯째, 세조의 신미가 주석하고 있는 복천암 방문 등을 확인하였다. 나아가 훈민정음 창제 관련 설화를 단순한 스토리 수준에 머물게 하지 않고 이를 스토리텔링 하여 국가적 혹은 지역적 축제로 승화시킨다면 융복합 문화콘텐츠 활성화의 좋은 방안이 될 수 있음에 그 의의를 두었다.
