“…JBC, characterized by their pitch-black coat color, are traditionally regarded as a source of top-quality food that has several health benefits. JBC beef was regularly consumed by the Korean royal family since the Goryeo Kingdom era because it is a chewy meat fillet with excellent elasticity and fine marbling, and it contains tightly lodged unsaturated fatty acids such as oleic and linoleic acids [ 18 ]. JBC are an endangered breed, which prompted initiation of the JBC Conservation Program in the early 1990s.…”

To preserve Jeju black cattle (JBC; endangered native Korean cattle), a pair of cattle, namely a post-death cloned JBC bull and cow, were produced by somatic cell nuclear transfer (SCNT) in a previous study. In the present study, we examined the in vitro fertilization and reproductive potentials of these post-death cloned animals. Sperm motility, in vitro fertilization and developmental capacity were examined in a post-death cloned bull (Heuk Oll Dolee) and an extinct nuclear donor bull (BK94-13). We assessed reproductive ability in another post-death cloned cow (Heuk Woo Sunee) using cloned sperm for artificial insemination (AI). There were no differences in sperm motility or developmental potential of in vitro fertilized embryos between the post-death cloned bull and its extinct nuclear donor bull; however, the embryo development ratio was slightly higher in the cloned sperm group than in the nuclear donor sperm group. After one attempt at AI, the post-death cloned JBC cow became pregnant, and gestation proceeded normally until day 287. From this post-death cloned sire and dam, a JBC male calf (Heuk Woo Dolee) was delivered naturally (weight, 25 kg). The genetic paternity/maternity of the cloned JBC bull and cow with regard to their offspring was confirmed using International Society for Animal Genetics standard microsatellite markers. Presently, Heuk Woo Dolee is 5 months of age and growing normally. In addition, there were no significant differences in blood chemistry among the post-death cloned JBC bull, the cow, their offspring and cattle bred by AI. This is the first report showing that a pair of cattle, namely, a post-death cloned JBC bull and cow, had normal fertility. Therefore, SCNT can be used effectively to increase the population of endangered JBC.

Various wind turbines have been developed and operated in distribution systems and transmission systems. The usage of wind power is now rapidly growing worldwide and some leading countries in wind power technologies have been developing new strategies and enhanced requirements for power system security and electrical power quality. But most of power systems have not prepared for them yet. Given the fact that the renewable energy sources, such as wind power, photovoltaic, fuel cells will be getting more importance for the future energy systems with the benefit of emission trading, most of developing countries and power systems that are not preparing for such movement should make their future plan not only for the power system security, but also for their economic development. In this paper, wind power technologies, which is one of the most promising alternative energy sources, is summarized from the viewpoint of power system operation and control.

“…According to the 7th Electric Power Supply and Demand plan of Korea, Jeju's power demand and peak power in 2029 are forecasted to be 7234 GWh, and 1132 MW, respectively, yielding growth of factors of 1.5 and 1.3, respectively, from 2016 values, as shown in Figure 1 [40]. …”

Electric vehicles (EVs), one of the biggest innovations in the automobile industry, are considered as a demand source as well as a supply source for power grids. Studies have been conducted on the effect of EV charging and utilization of EVs to control grid peak or to solve the intermittency problem of renewable generators. However, most of these studies focus on only one aspect of EVs. In this work, we demonstrate that the increased demand resulting from EV charging can be alleviated by utilizing idle EV charging stations as a vehicle-to-grid (V2G) service. The work is performed based on data from Jeju Island, Korea. The EV demand pattern in 2030 is modeled and forecasted using EV charging patterns from historical data and the EV and charging station deployment plan of Jeju Island's local government. Then, using a Monte Carlo simulation, charging and V2G scenarios are generated, and the effect of V2G on peak time is analyzed. In addition, a sensitivity analysis is performed for EV and charging station deployment. The results show that the EV charging demand increase can be resolved within the EV ecosystem.
