  • The second venture "boom" diffusion strategy can be confirmed to be focused only on financing investment and finance, including achieving 5 trillion won annually in new venture investments, creating 20 unicorns, activating M&As and creating dynamic recovery markets. Of course, existing studies show that the fund is a very important policy for corporate growth, but various policy support will be needed to effectively scale up. To overcome these limitations, the scale-up support policies already in operation are analyzed by introducing scale-up policies in advanced countries such as the U.S. and Britain. It also aims to analyze domestic scale-up policies to draw up implications for establishing more effective scale-up policies. Academically, we are very lacking in research on scale-up at home and abroad, and we propose suggestions through this comparative study of policy cases to contribute to the promotion of various studies related to the scalability aspects of future research topics related to scale-up.

  • Chemical and Pb isotope analysis were performed in order to determine the origin of bronze artefacts excavated from the Inyongsaji site in South Korea. The result of ICP-MS shows that they are tin bronzes in which lead was not intentionally added during production. Pb isotope data analyzed by TIMS are plotted in the southern region of Korea and China of the distribution map drawn by Mabuchi(1985). On the other hand, the identical isotope data are plotted in the Taebaek basin and the Olcheon metamorphic belt correspondent to zone2 and zone3 respectively. It is believed that the isotope data on the tin bronzes which have very low lead content can be used to trace the origin of copper ore rather than those of either lead or tin ore. Pb istope analysis allows diverse interpretation as it can be applied to any object containing trace amounts of lead. In addition, accumulation of isotope data as well as further studies will improve reliability of the provenance studies.

  • Coronavirus disease 19 (COVID-19) is caused by SARS-CoV-2 (Severe Acute Respiratory SyndromeCoronavirus 2). To date, seven coronaviruses that can infect humans were reported. Among them, infections with four coronavirus strains (HCoV-229E, HCoV-OC43, HCoV-NL63, and HCoV-HKU1) resulted in mild symptoms such as common cold, whereas SARS-CoV and MERS-CoV caused severe symptoms and epidemics in 2002 and 2012, respectively. In the most recent, SARS-CoV-2 was first reported in Wuhan, China in December 2019 and became a notorious cause of the ongoing global pandemics. To diagnose, treat, and prevent COVID-19, the development of rapid and accurate diagnostic tools, specific therapeutic drugs, and safe vaccines essentially are required. In order to develop these powerful tools, it is prerequisite to understand a phenotype, a genotype, and life cycle of SARS-CoV-2. Diagnostic techniques have been developing rapidly around world and many countries take the fast track system to accelerate approval. Approved diagnostic devices are rapidly growing facing to urgent demand to identify carriers. Currently developed commercial diagnostic devices are divided into mainly two categories: molecular assay and serological & immunological assay. Molecular assays begins the reverse transcription step following polymerase chain reaction or isothermal amplification. Immunological assay targets SARS-CoV-2 antigen or anti-SARS-CoV-2 antibody of samples. In this review, we summarize the phenotype, genome structure and gene expression of SARS-CoV-2 and provide the knowledge on various diagnostic techniques for SARS-CoV-2.

  • The purpose of this study was to investigate the recognition and satisfaction with the menu quality of food services in an immigration detention center. The survey was conducted from January 22, 2010 to April 22, 2010 by questionnaires. A survey with 265 respondents was conducted and data analyzed by the SAS Program. In analyzing leftovers, the most common was kimchi (37.61%), followed by breads (21.52%), and beans/bean curd (17.99%). The common cause for leftover were undesirable taste (31.84%), sickness or a lack of desire for eating (19.85%). In terms of cooking methods, stir-frying, broiling, and frying were highly preferred to steaming, boiling, and salting. In the analysis of preferences in the taste and satisfaction of food service, there were significant differences in hot, sour, bitter, and light tastes (p<0.05, p<0.01, p<0.001). Satisfaction was low with hot and light tastes, whereas sour and the bitter tastes showed a high degree of satisfaction. In the opinions for quality improvement, most immigrants wanted a tastier food supply (58.69%), a diverse food supply (40.54%), and clean utensils (36.68%). In the analysis of the gap between importance and performance, food taste, variety, and sanitation were recognized as poorly performed, causing major dissatisfaction with the food. The overall satisfaction score was 'average' (3 points out of 5 points) with 3.26 points. The satisfaction score showed insignificant difference depending on religions and duration of stay in Korea, but showed significant differences depending on nationality (p<0.001).

  • The paper describes the objectives of Yellow Sea Large Marine Ecosystem (YSLME) project, focusing on procedural and practical aspects. YSLME is a highly productive sea yet possibly one of the most impacted large marine ecosystems, in terms of anthropogenic stressors, due the enormous coastal population. The aim of the YSLME project is the reduction of ecosystem stress through identification of the environmental problems in the Transboundary Diagnostic Analysis (TDA) that are then addressed in the Strategic Action Programme (SAP). One of the major problems found to be affecting biological diversity is habitat modification through wetland reclamation, conversion and degradation. Since the early 1900's more than 40% of intertidal wetlands have been reclaimed in Korea, and 60% of Chinese coastal wetlands have been converted or reclaimed. Damaging fishing practices, pollution and coastal eutrophication have further degraded the coastal environment reducing the biological diversity. To combat this loss, the YSLME project has mounted a public awareness campaign to raise environmental consciousness targeted at all different levels of society, from politicians at parliamentary workshops, local government officer training events, scientific conferences and involvement of scientists in the project research and reporting, to university and high school students in our visiting internship programmes and environmental camps. We have also built networks through the Yellow Sea Partnership and by liaising and working with other environmental organizations and NGOs. NGO's are recognised as important partners in the environmental conservation as they already have extensive local networks that can be lacking in international organisations. Effective links have been built with many of these NGOs through the small grants programme. Working with WWF's YSESP project and other academic and research institutions we have conducted our own biodiversity assessments that have contributed to the science-based development of the SAP for the YSLME. Our regional targets for biodiversity outlined in the SAP include: Improvements in the densities, distributions and genetic diversity of current populations of all living organisms including endangered and endemic species; Maintenance of habitats according to standards and regulations of 2007; and a reduction in the risk of introduced species. Endorsement of the SAP and its successful implementation, during the proposed second phase of the YSLEM project, will ensure that biological diversity is here to benefit future generations.

  • Forest landscape models (FLMs) can be used to investigate the complex interactions of various ecological processes and patterns, which makes them useful tools to evaluate how environmental and anthropogenic variables can influence forest ecosystems. However, due to the large spatio-temporal scales in FLMs studies, parameterization and validation can be extremely challenging when applying to new study areas. To address this issue, we focused on the parameterization and application of a spatially explicit forest landscape model, LANDIS-II, to Mt. Gyebang, South Korea, with the use of the National Forest Inventory (NFI) and long-term ecological research (LTER) site data. In this study, we present the followings for the biomass succession extension of LANDIS-II: 1) species-specific and spatial parameters estimation for the biomass succession extension of LANDIS-II, 2) calibration, and 3) application and validation for Mt. Gyebang. For the biomass succession extension, we selected 14 tree species, and parameterized ecoregion map, initial community map, species growth characteristics. We produced ecoregion map using elevation, aspect, and topographic wetness index based on digital elevation model. Initial community map was produced based on NFI and sub-alpine survey data. Tree species growth parameters, such as aboveground net primary production and maximum aboveground biomass, were estimated from PnET-II model based on species physiological factors and environmental variables. Literature data were used to estimate species physiological factors, such as FolN, SLWmax, HalfSat, growing temperature, and shade tolerance. For calibration and validation purposes, we compared species-specific aboveground biomass of model outputs and NFI and sub-alpine survey data and calculated coefficient of determination (R2) and root mean square error (RMSE). The final model performed very well, with 0. 98 R2 and 8. 9 RMSE. This study can serve as a foundation for the use of FLMs to other applications such as comparing alternative forest management scenarios and natural disturbance effects.

  • Taking the painting, 「Landscape of the Jiuqu River in the Wuyi Mountain」 as the study object, which was produced in the middle of Qing Dinasty and collected by the British Library, this paper analyzes the scenery names recorded in the painting, and describes the landscape of the mountain, port and ships, architectural elements, civil elements, character, stone inscription and other scenery in the painting. The investigation results of the cultural landscape properties of each Gok are as follows: According to statistics, there are 28 architectural elements in the painting, including 7 pavilions (25%), 4 temples (14.3%), 3 Colleges and Taoist temple (10.7%), 2 Dowon(道院) and villages (7.1%); 29 civil elements, including 9 holes (31%), 6 Historical Sites (20.7%), 3 Stations(臺) (10.3%), 2 Ferries, 2 Bridges, and 2 Ponds (6.9%), 1 Garden, 1 Gate, 1 Mine(坑), 1 Well and 1 Remains(3.4%). These physical factors and civil factors are the important relics reflected the cultural landscape attributes of Wuyi-Gugok in the middle of the 18th century. Among the shape element in each Gok, the 1st Gok have 12 shape elements(21.1%), the 5th Gok 11(19.3%), the 4th Gok 9(15.8%), the 9th Gok 8(14%), the 3rd Gok 7(12.3%), the 6th Gok 4(7%), the 2nd Gok 3(5.3%), the 7th Gok 2(3.5%), and the 8th Gok 1(2%). Through collation, it is found that the 1st Gok, 5th Gok and 4th Gok have more prominent cultural landscape characteristics. In addition, according to the description of scenic spot types in 『Muisanji(武夷山志)』, there are 38 types of scenery description in the painting, of which, the three scenery of big rock, peak, small rock occupy the vast majority. This reflects the Danxia(丹霞) landform characteristics of Wuyi-Gugok. The cultural connotation of Wuyi Mountain expressed and contained in the painting is analyzed and interpreted, and it is found that the Jiuqu(九曲) River in the Wuyi Mountain has Neo-confucianism culture, Taoism culture, Buddhism culture, Tea culture and so on. In addition, among the 171 scenery names shown in the painting, there are altogether 7 stone inscriptions that are consistent with or have the same meaning as the rock inscriptions site, including 3 for inscriptions praising the landscape, 3 for philosophical inscription and 1 for auspicious language inscription, which is considered as the important basis for the mutual textuality between the pictures and the stone inscriptions.

  • The radiation observation data will be used importantly in research field such as climatology, weather, architecture, agro-livestock and marine science. The Ieodo Ocean Research Station (IORS) is regarded as an ideal observatory because its location can minimize the solar radiation reflection from the surrounding background and also the data produced here can serve as a reference data for radiation observation. This station has the potential to emerge as a significant observatory and join a global radiation observation group such as the Baseline Surface Radiation Network (BSRN), if the surrounding of observatory is improved and be equipped with the essential radiation measuring instruments (pyaranometer and pyrheliometer). IORS has observed the solar radiation using a pyranometer since November 2004 and the data from January 1, 2005 to December 31, 2015 were analyzed in this study. During the period of this study, the daily mean solar radiation observed from IORS decreased to $-3.80W/m^2/year$ due to the variation of the sensor response in addition to the natural environment. Since the yellow sand and fine dust from China are of great interest to scientists around the world, it is necessary to establish a basis of global joint response through the radiation data obtained at the Ieodo as well as at Sinan Gageocho and Ongjin Socheongcho Ocean Research Station. So it is an urgent need to improve the observatory surrounding and the accuracy of the observed data.

  • Gestational diabetes mellitus (GDM) is defined as glucose intolerance discovered or onset during pregnancy and attention is needed because of increased risk of perinatal morbidties and higher incidence of diabetes afterward. This study was performed to identify dietary factors associated with the development of gestational diabetes mellitus (GDM). Developed food frequency questionnaire containing 192 food items were used to assess nutritional status of 246 control subjects and 104 GDM subjects. Food habits of subjects were examined in the questionnaire. The more irregularity and less variety of meal were found in GDM group compared to control group and GDM group tended to eat rapidly and do not like vegetables and greasy foods. Total score of food habits in GDM was lower than control group, which suggests that GDM group have undesirable food habits. Mean daily energy and carbohydrate intakes of GDM group were higher than those of control group, and percent energy from protein was significantly higher in control. Nutrient density of protein, calcium, phosphorus and vitamin BI of GDM group was significantly lower than those of control group. Therefore dietary quality of GDM group was lower than that of control group. Odds ratio for GDM was high when energy and carbohydrate intakes were high. And when the intakes of rice, noodle, shiruduk, hamburger, boiled egg, steamed pork shank were high, the odds ratio for GDM was high. These results indicate that the amount and frequencies of several foods and dish items were related with the occurrence of GDM subjects. On the whole, GDM subjects consumed more cereals and less vegetables and less legumes. From these results, pregnant women with GDM tended to have unhealthy food habits, and carbohydrate intake was important dietary factors on the onset of GDM.
