    Abstract Recent statistics of Coronavirus diseases in Korea are studied with respect to many other countries. It is found that as of 8 February 2021, Korea has recorded 15.8 patients per 10,000 people, and this is used to calculate ratio to compare with other countries. On average, the number of Coronavirus patients in the world is 136.2 that is 8.6 times more than in Korea. The number of Covid-19 patients recorded in Korea is relatively smaller than other countries. There was no clear evidence on the atmospheric transport of Coronaviruses over 1 km to cause infection to other people. The infection of Coronaviruses appeared to occur mainly by close contact with an infected person or by airborne droplets in confined indoor environments, as noted earlier (Lancet, Respir Med 8(12):1159, 2020). To reduce the transmission of Coronavirus and related infections, the wearing of a pollution filter (mask) covering the nose and mouth is mandatory for Coronavirus patients. For the general public, however, we have invented a filter which covers only the nose. When there is no need for conversation and deep breathing, the nose band would be sufficient to filter out Coronavirus and air pollutants. Meanwhile, air and sea port activities including ground transport continued and strict policy on people mingle was not tightly enforced, and control measures to reduce infection were not so effective. However, it is believed that consuming fermented Korean spicy Kimchee and hot peppery soup plus warm rice tea helps in washing Coronaviruses around the throat deep down to the stomach. We find that cleansing the mouth and throat deeply including pathway is better than doing shallow gargling. A possible mechanism for cleansing the mouth and throat of Coronaviruses is here explored. This could have contributed to the relatively small number of Coronavirus patients observed in Korea.

    Abstract The pandemic of Coronavirus diseases occurred in the Republic of Korea from 19 January 2020. By March 2020, Korea had reported the second largest number of Coronavirus patients in the world. On the anniversary date (2021), however, with a 51.3 M population, Korea has had 73.115 K patients with 1.283 K deaths, and this stands at 86th in the world. On average, Korea has 14.3 patients per 10,000 people. Air-parcel trajectory analysis and airflows show that in the general westerly region, air parcels and pollutants could flow out and in all directions. This suggests initially that Coronaviruses from source areas in China could transmit to many sink regions and sectors including 228 subdivided counties in Korea. However, there were only relatively small numbers of Coronavirus patients in western sea sides of the Korean Peninsula in comparison with large numbers of Coronavirus disease patients in cities and in eastern sides. In particular, three counties in Korea, including Ong-jin, Mooju and Chang-heung, have zero patients of Coronavirus diseases. This suggests that a long-distance transmission of Coronavirus from Wuhan and other infected cities in China to western Korea likely did not occur. Moreover, there was no evidence on the potential transmission of Coronavirus from neighboring large cities to the above-mentioned isolated counties in Korea which are only 10 ~ 50 km away. In the biosphere, during the transmission stage, the inactivation of Coronavirus by UV rays appeared to occur effectively in 30 ~ 120 min, in agreement with the result of satellite and modeling studies. In turn, the air transmission of Coronaviruses and pollution from China and neighboring cities in Korea apparently had no impact to cause Coronavirus diseases at the 228 counties in Korea. The infection and spreading of Coronavirus diseases to other people in Korea mainly appeared to occur in confined indoor air environments. With the absence and lack of UV rays in indoor environments, Coronaviruses would be active there for hours or days longer than in the outdoor environments.

    Abstract The Rare-isotope Accelerator complex for ON-line experiments is a heavy-ion accelerator facility that accelerates a stable or rare isotope beam up to 400 kW with an energy of 200 MeV/u. Various heavy-ion beams are generated from the Electron Cyclotron Resonance Ion Source, with an energy of 10 keV/u and separated according to A/Q at the first dipole magnet (DM). To measure beam transverse emittance at the Low Energy Beam Transport section, two Allison scanners are installed behind the DM for the X and Y directions. It consist of a servo motor for driving, a Faraday cup for current measurement, deflection plates, and electronic device. The measurable range of beam angle in of the Allison scanner is determined by the structure of the deflection plate and designed based on mathematical calculations. Experimental Physics and Industrial Control System (EPICS) is adopted to integrate and control a variety of devices. To control the complex measurement sequence of the Allison scanner, an EPICS sequencer module was used. Normalized emittance is calculated by python code with Pyepics module using phase space distribution data. In this paper, we present the detailed design of the Allison scanner, the configuration of the control system, and the experimental results using an Ar9+ 30 μA beam.

    Abstract Treatment for ranula is classified into three categories depending on how the leaking saliva is managed: removal of the leaking site by intraoral or transcervical resection of the sublingual gland; formation of a drainage tract through the wall of the pseudocyst by micromarsupialisation or marsupialisation; or sealing of the site of the leak by inducing fibrosis with a sclerosing agent. Resection of the sublingual gland is probably the option most likely to be curative for both oral and plunging ranula considering their pathophysiology. Although alternative treatments have been introduced to avoid the invasiveness of resection of the gland, their outcomes have been inconsistent. The objective of this study therefore was to help decision-making by providing more integrated rates of cure, consistency of treatment, and morbidity, depending on types of treatment used in previous series of cases. We used proportion meta-analysis of 39 such published series, and the most curative treatment for oral ranula was intraoral resection of the sublingual gland. Micromarsupialisation and its modification showed cure rates comparable with those of resection of the gland, but these were moderately inconsistent. In the treatment of plunging ranula, there was no significant difference in cure rate between the intraoral and transcervical approaches, although they both showed higher cure rates than injection of OK-432. Comparisons of morbidity were available for patients who had developed nerve dysfunction and haematoma after the intraoral and transcervical approaches and there was no significant difference between the two, though the morbidity was higher after the transcervical than that after the intraoral approach. In conclusion, intraoral resection of the sublingual gland is sufficient treatment with a tendency to have fewer complications than that in the transcervical approach.

    Abstract To compare the diagnosis andtreatment rates of osteoporosis and diabetes in Korea, a nationwide database was used. The results showed that although osteoporosis management is improving, it is still lower compared with that of diabetes; thus, further efforts are needed in this regard.
    Introduction: This study aimed to re-evaluate the diagnosis and treatment of osteoporosis from the KNHANES 2016-2017 and compare the temporal change of the rate with those of diabetes as another prevalent chronic disease in South Korea.
    Methods: The prevalence of osteoporosis in 2016 was estimated using the previous data classified by age groups (50-59,60-69, and ≥70years) and the 2016 Korean census data. The physician diagnosis and treatment rates of osteoporosis in adults aged ≥50years were estimated using the 2016-2017 KNHANES data. The physician diagnosis and treatment rates of diabetes were evaluated using the KNHANES 2008-2009 and 2016-2017 data.
    Results: The estimated physician diagnosisrate of osteoporosis increased from 29.9% in females and 5.8% in males in 2008-2009 to 62.8% in females and 22.8% in males in 2016-2017. The treatment rate for the estimated total number of patients with osteoporosis increased from 14.4% in females and 3.8% in males in 2008-2009 to 32.2% in females and 9.0% in males in 2016-2017. An increasing trend in the estimated treatment rateof physician-diagnosed osteoporosis patients was not observed (48.3% [2008-2009] vs 51.5% [2016-2017] in females; 42.6% [2008-2009] vs 42.2% [2016-2017] in males). The physician diagnosis and treatment rates of diabetes were considerably better and more stable than those of osteoporosis.
    Conclusion: Osteoporosis management in South Korea is improving but is insufficient compared with diabetes management. More extensive efforts are needed to improve the diagnosis and treatment rates of osteoporosis.

    Abstract M6 (Reg. No. GP-1, BS 228) is a diploid self-compatible inbred line of the potato wild relative Solanum chacoense. It is a vigorous, homozygous breeding line derived by self-pollinating the diploid wild potato relative S. chacoense for seven generations. While most wild Solanum species are self-incompatible, this clone is homozygous for the dominant self-incompatibility inhibitor gene Sli. In addition, it is homozygous for 90% of single-nucleotide polymorphism markers in the Infinium Array developed by the SolCAP consortium. M6 is vigorous and both male and female fertile, producing seeds in crosses to diploid cultivated and wild potato germplasm. These traits enable us to systematically develop diploid inbred lines, which was not possible in potato breeding until the discovery of Sli. M6 produces tubers under both short and long photoperiods, unlike other wild potato relatives. In addition, M6 has several desirable traits, including high dry matter content, good chip processing quality, and resistance to soft rot and Verticillium wilt. M6 is being used to develop recombinant inbred line populations.

    Abstract A cDNA library was constructed using mRNA prepared from leaves of watermelon [Citrullus lanatus (Thunb.) Matsum&Nakai] at the vegetative stage. Randomly selected cDNA clones were sequenced in order to identify potentially informative genes. Database comparisons indicated that out of the 704 watermelon cDNA clones, 399 clones (56.7 %) revealed a high degree of sequence similarity to genes from other organisms. These expressed sequence tag clones were divided into ten categories depending upon gene function. Since this kind of experiment has not previously been carried out in this genome, random nucleotide sequencing of these cDNAs could contribute considerable information concerning the novel genes in this organism.

    Abstract DNA (antisense and other oligonucleotides) drug design represents a direct genetic approach for cancer treatment. Such an approach takes advantage of mechanisms that activate genes known to confer a growth advantage to neoplastic cells. The ability to block the expression of these genes allows exploration of normal growth regulation. Progress in DNA drug technology has been rapid, and the traditional antisense inhibition of gene expression is now viewed on a genomic scale. This global view has led to a new vision in antisense technology, the elimination of nonspecific and undesirable side effects, and ultimately the generation of more effective and less toxic nucleic acid medicines. Several antisense oligonucleotides are in clinical trials, are well tolerated, and are potentially active therapeutically. DNA drugs are promising molecular medicines for treating human cancer in the near future.
