DO-278A는 소프트웨어 인증 절차를 제공할 목적으로 만들어진 것은 아니지만, 소프트웨어 개발 절차를 설명하는 것으로 지상용 항공장비의 소프트웨어를 만드는데 적절한 역할을 수행할 수 있다. 대체적으로, 수명주기증거품(life cycle evidence)을 통해 프로세스가 정확하고 적합하게 이행되었다는 것을 증명할 수 있다면 소프트웨어는 적합성을 확인을 받을 수 있다. 본 논문에서는 국토부 R&D로 개발되고 있는 항공기 지상이동유도 및 통제시스템(Advanced-Surface Movement Guidance & Control System, A-SMGCS)의 소프트웨어 개발 및 검증에 DO-278A 절차를 적용한 방안을 제시하고자 한다.

In this paper, The statistical properties of ocean waves in the sea area of Hong-do, Korea are examined based on 1998-2002's wave data from a directional wave buoy. Wave data aquisition rate, mean wave heights, frequency of wave direction are summarized. Wave height and period scatter diagrams and n-year return period wave heights are estimated. Wave periods of maximum wave heights are also estimated. Large amplitude wave characteristics during the typhoon Prapiroon in 2000, Rusa in 2002 are also examined.

This study was performed on 302 cases of leptospirosis, tsutsugamushi disease and hemorrhagic fever with renal syndrome(HFRS) which occurred in Chonnam(Do) in 1991 through 1993. The results were as follows : 1. 81.8% of the patients with Leptospirosis and 54.5% of the HFRS patients were men while 61.4% of the patients with tsutsugamushi disease were women. 2. Most patients lived in rural areas(Gun), their educational level was elementary School or lower and their occupations were either farmer or jobless. 3. Peak ages were 40s for leptospirosis(36.4%) and 50s for tsutsugamushi disease and HFRS(32.9% and 36.4% respectively). 4. The high incidence areas of tsutsugamushi disease were northern, eastern and a diagonal line, from northeast to southwest, of the Chonnam area, and these are consistent with a mountainous district. 5. In monthly distribution leptospirosis was higher in Sep. and Oct., and tsutsugamushi disease and HFRS were higher in Oct. and Nov. 6. The first case is occurring and the last case shows up later than in past years.

The Gyeonggi-do Agricultural Research and Extension Services has developed a web-site (www.epilove.com) in collaboration with EPINET to provide information on agricultural weather and rice disease and insect pest management in Gyeonggi-do. Weather information includes near real-time weather data monitored by automated weather stations (AWS) installed at rice paddy fields of 11 Agricultural Technology Centers (ATC) in Gyeonggi-do, and weekly weather forecast by Korea Meteorological Administration (KMA). Map images of hourly air temperature and rainfall are also generated at 309m x 309m resolution using hourly data obtained from AWS installed at 191 locations by KMA. Based on near real-time weather data from 11 ATC, hourly infection risks of rice blast, sheath blight, and bacterial grain rot for individual districts are estimated by disease forecasting models, BLAST, SHBLIGHT, and GRAINROT. Users can diagnose various diseases and insects of rice and find their information in detail by browsing thumbnail images of them. A database on agrochemicals is linked to the system for disease and insect diagnosis to help users search for appropriate agrochemicals to control diseases and insect pests.

This study was done to provide an analytical overview on the latest malaria infection clusters by evaluating temporal trends during 2010-2019 in Korea. Incheon was the most likely cluster (MLC) for all cases of malaria during the total period. MLCs for P. falciparum, vivax, malariae, ovale, and clinically diagnosed malaria without parasitological confirmation were Jeollanam-do, Incheon, Gangwon-do, Gyeongsangnam-do, and Jeollabuk-do, respectively. Malaria was decreasing in most significant clusters, but Gwangju showed an increase for all cases of malaria, P. vivax and clinically diagnosed cases. Malaria overall, P. falciparum and P. vivax seem to be under control thanks to aggressive health measures. This study might provide a sound scientific basis for future control measures against malaria in Korea.

This study was survey a flora and life form spectrum of 11 uninhabited islets, in jeju-do. The vascular plants of each uninhabited islets were summarized as Beomseom 159 taxa, Chagwi-do 136 taxa, Daryeo-do 81 taxa, Hyeongje-do 61 taxa, Jigwi-do 39 taxa, Munseom 147 taxa, Ran-do 58 taxa, Saeseom 65 taxa, Seogeondo 60 taxa, Seopseom 183 taxa and Wa-do 46 taxa. Floristic richness was in order analyzed to be Seogeon-do 28.62, Ran-do 19.24, Daryeo-do 18.53, Wa-do 16.42, Munseom 16.14, Hyeongje-do 14.76, Seopseom 13.32, Beomseom 13.24, Chagwi-do 6.15, Saeseom 5.86 and Jigwi-do 2.51. Life form spectrum was surveyed to H-$D_5$-$R_4$-e; hemieryptophyte(H) 26.8%, not production seeds($D_5$) 54.4%, clonal growth by stolons and struck roots($R_4$) 46.9% and erect form(e) 30.3%. According to the life form spectrum hemieryptophyte dominated high portions, which suggests islet in jeju-do has hemieryptophytic climate and similar to middle parts in Korean Peninsular. However, were noticed by that it has more therophytes. As a result, Partially shows the characteristics change from the temperate climate to the warm temperate climate or a semitropical climate by a climatic change.

Plum pox virus (PPV) is a significant viral disease in Prunus spp. worldwide. A nationwide survey was started in Prunus spp. orchards, since PPV was first detected from peach in Korea, 2015. During 2016-2017, samples were collected from 30,333 trees in 1,985 orchards of stone fruits in 8 provinces and 4 cities, Korea and tested by RT-PCR using specific PPV primer set. As a result, 21 trees including peach (9 trees), Japanese apricot (4 trees), plum (1 tree), apricot (7 trees) in 10 orchards were infected and controlled by eradication program. Amplicons of the expected size (547 bp) were obtained from total RNA of seven peach trees in 2016, and directly sequenced. BLAST analysis revealed the highest nucleotide (NT) identity (99%) with a PPV D isolates (LC331298, LT600782) in Genbank. The seven isolates from shared nt sequence identities of 98 to 100% with one another. Phylogenetic analysis showed the isolates in peach clustered closely with the PPV-D isolates from Korea, Japan, USA, and Canada. This is, to our knowledge, the first report of the presence of PPV in Prunus spp. orchards in Korea, 2016-2017, we hope that our results and efforts will contribute to effective measures for eradication of PPV.
