Background : Medicinal crop seeds have low homogeneity and quality of seeds and seedlings because they are self-seeded or produced in farmhouses. Therefore, it is necessary to develop systematic technology for establishment and distribution of seed production technology for stable production of domestic medicinal crops. Methods and Results : The test Agastache rugosa O. K. Kuntze. variety was Jeonnam local variety (Naju species) and was carried out in 2017. The research was divided into two types; seed yield test according to seeding time and seed yield test according to fertilization method. Sowing of the seed yield test according to the seeding time was sown on the seedling tray 4 times from 20 th March to 20 th May at intervals of 20 days, and after the nursery, they were transplanting. The fertilization gave the standard fertilization (N-P-K-compost applied at 12-16-10-600 ㎏/10a) amount before implantation. Sowing of the seed yield test according to fertilization method was sowing in the middle of April. The seedlings were grown for 60 days and then transplanted in the middle of June. Four different fertilization methods were applied and cultivated. Planting density of both tests were spaced 30 ㎝ apart in rows 20 ㎝ apart with non-woven fabric mulching cultivation. The plot design was a randomized block 3 repetitions. Seed yields at the seeding time were the highest at 67 ㎏/10a in sowing on March 20, and the yields decreased as the seeding time passed. Seed yield according to fertilization method was the highest at 75 ㎏/10a in 25% increase control and lowest at 46 ㎏/10a in 50% diminish control. Conclusion : From the above results, we may suggest that the seedlings should be cultivated in the middle of March and cultivated by increasing the fertilization rate by 50%.

Both the propagation velocity and the direction of atmospheric waves are important factors for analyzing and forecasting meteo-tsunami. In this study, a total of 14 events of meteo-tsunami over 11 years (2006-2016) are selected through analyzing sea-level data observed from tidal stations along the west coast of the Korean peninsula. The propagation velocity and direction are calculated by tracing the atmospheric disturbance of each meteo-tsunami event predicted by the WRF model. Then, the Froude number is calculated using the propagation velocity of atmospheric waves and oceanic long waves from bathymetry data. To derive the critical condition for the occurrence of meteo-tsunami, supervised learning using a logistic regression algorithm is conducted. It is concluded that the threshold distance of meteo-tsunami occurrence, from a propagation direction, can be calculated by the amplitude of air-pressure tendency and the resonance factor, which are found using the Froude number. According to the critical condition, the distance increases logarithmically with the ratio of the amplitude of air-pressure tendency and the square of the resonance factor, and meteo-tsunami do not occur when the ratio is less than 5.11 hPa/10 min.

Meteo-tsunamis are tsunamis that are typically caused by strong atmospheric instability (e.g., pressure jumps) in low pressure systems, but some meteo-tsunamis in winter can be caused by local atmospheric instability in high pressure systems (e.g., the Siberian High). In this study, we investigated a meteo-tsunami event related to a high pressure system that occurred during winter on the Yellow Sea in 2005. Sea level data from tidal stations were analyed with a high-pass filter, and we also performed synoptic weather analyses by using various synoptic weather data (e.g., surface weather charts) collected during the winter season(DJF) of 2005. A numerical weather model (WRF) was used to analyze the atmospheric instability on the day of the selected event (21 Dec. 2005). On the basis of the results, we suggest that the meteo-tsunami triggered by the high pressure system occurred because of dynamic atmospheric instability induced by the expansion and contraction of the Siberian High.
