This study is to estimate the possible damage area of greenhouse by heavy snowfall event using terra MODIS snow cover area (SCA) and the ground measured snowfall data (GMSD). For the 4 heavy snowfall events of January 2001, March 2004, December 2005 and January 2010, the areas exceeding the design criteria of snowfall depth for greenhouse breaking were extracted by coupling the MODIS SCA and GMSD. The main damaged regions were estimated as Gangwon province in 2001, Chungbuk and part of Gyeongbuk province in 2004, Jeonbuk and Jeonnam province in 2005, and Gangwon and part of Gyeonggi province in 2010 respectively. Comparing with the investigated number of greenhouse damaged data, the estimated areas reflected the statistical data except 2001. The 2001 greenhouse damages were caused by the high wind speed (35.7m/sec) together with snowfall. The results of this study can be improved if the design criteria of wind speed is added.

With the Chinese government's attention to the artificial intelligence industry, the Chinese government has invested a lot in it recently. Of course, the importance of artificial intelligence industry for China's economic development is increasingly significant. The advent of artificial intelligence boom has also triggered a large number of scientists to analyze the impact of artificial intelligence on economic growth. Therefore, this paper use 31 China's cross-province panel data to study the effect of artificial intelligence on economic growth. Via empirical analyses under a series of econometric methods such as the province and year fixed effect model, the empirical result shows that artificial intelligence has a positive and significant effect on economic growth. Namely, the artificial intelligence is a new engine for economic growth. Meanwhile, the empirical results also indicate that the investment and consumption has a significant and positive effect on economic growth. Oppositely, the inflation and government purchase have a significant negative effect on economic growth. These findings in this paper also provide some important evidences for policy-makers to perform precise behaviors so as to promote the economic growth. Moreover, these finding enriches existing literature on artificial intelligence and economic growth.

This paper aims to interrogate the layered and dependent structure of the modern and official document management in Korea and Japan from 1894 to 1910. The focus of its study is on documents related with the strategic infrastructure construction in Jeonbuk Province through an analysis from the perspective of historic archival studies. For this study, the chosen period was when Japanese imperialists were on their way to seize the Korean official archival system. As such, our objects are the documents connected with the institution of the Japanese resident-general system in Korea and its infrastructural constructions as part of Japan's war plans of invading the continent. Among others, we examined the documents of the strategic infrastructure construction around Jeonju in Jeonbuk Province by Imperial Japan, in order to wage the Sino-Japanese War and subdue the Donghak Peasant Revolution. More specifically, we illuminate the sources and organization of the approval of the original documents in a higher level that is relevant to the determination of political, financial, and personnel matters, which were designed for the Japanese governmental rule over Korea from the era of the Gabo Reform to the period of the Japanese resident-generals, as well as analyze the actual states of the official documents ina lower level, which were drawn up by Korean government and the resident-general. Consequently, this paper suggests that official Korean archival system at this time must be understood under the context of a layered and dependent structure within the vertical connections between Korea and Japan, and not from the point of view of a national history.

Recently, the major viral diseases, Newcastle disease (ND), infectious bronchitis (IB), low pathogenic avian influenza (LPAI), avian pneumovirus infection (APV), Marek's disease (MD) and infectious bursal disease (IBD), have led to huge economic losses in chicken industry of Korea. To evaluate prevalence of the major viral disease infections in broiler breeder and broiler farms, epidemiological survey has been conducted in Jeonbuk province from 2005 to 2007 by serological ELISA test for APV, PCR for MD, and RT-PCR for ND, IB, LPAI and IBD, respectively. A total of 424 cases was submitted to our laboratory for diagnosis of the major viral disease from broiler breeder and broiler farms in the above period. The diagnosed results were analysed for the detection rate of infections on basis of years, seasons and ages, respectively. This study was showed that the detection rates of ND and APV were considerably high for every years regardless of seasons and ages in both broiler breeder and commercial broiler. In comparison with detection rates of ND and APV, IB and LPAI were lower but detected around 10% for every years. Especially, detection rate of IB was significantly high in commercial broiler than in broiler breeder. Therefore, to minimize economic losses for broiler breeder and broiler farms, it will need for effective countermeasures to decrease detection rate of the viral respiratory diseases. Although the detection rates of MD and IBD were gradually decreased from 2005 to 2007 in both broiler breeder and commercial broiler, it will continually make an effort about disease control for increasing productivity in chicken industry.

The aim of this study was to examine the selected soil chemical properties of paddy fields in different topographic areas to efficiently manage nutrient valances of the paddy fields in Jeonbuk Province. Three-hundred soil sampling sites in paddy fields were selected from the different topographic areas in Jeonbuk Province. The soil samples were collected every four years from 1999 to 2015. Soil pH and exchangeable K and Mg concentrations declined during the experimental periods. However, almost all the chemical properties were within the proper levels for paddy soil, except exchangeable Mg concentration. Distributed areas of the paddy fields with soil pH below 5.5 continuously increased, but the paddy fields with lower concentrations of soil organic matter and available $P_2O_5$ than the proper levels declined after 2007. In addition, the paddy fields with available $SiO_2$ below the proper concentration decreased from 83.3% of the total paddy fields studied in 1999 to 61.0% of the total fields investigated in 2015. The paddy fields with lower exchangeable K and Mg than the proper levels increased after 2003 whereas the fields with lower exchangeable Ca concentration decreased. Dominant landform of coastal and plain areas was fluvio-marine plains that was distributed in 53.7% and 40.9%, respectively. Local valley and fans was a dominant landform of mountainous and middle-mountainous areas, which was 51.8% and 67.6%, respectively. Dominant soil textures distributed in coastal and plain areas were silty loam and loam. Those in mountainous and middle-mountainous areas were sandy loam and loam, respectively. Soil pH was relatively higher in coastal area and the comparatively higher content of soil organic matter was found in costal area than other areas. The concentrations of available $P_2O_5$, exchangeable Ca, and exchangeable Mg were generally higher in mountainous, coastal, plain areas, respectively, but available $SiO_2$ and exchangeable K concentrations were not significantly different among the different topographic areas.

This experiment was conducted to determine the change in weed flora with season and cultivated crop and land. There are 44 species in 38 genera and 18 families, consisting of 22 annual, 11 biennial and 9 perennial weeds in uplands in Jeonbug Province. Digitaria sanguinalis Scopol. occurred with the highest frequency of 67.2% and in decreasing order Portulaca oleracea L., Chenopodium album L. and Erigeron canadensis L. followed. About 60% of total sites studied indicated Simpson`s index ranging from 0.20 to 0.50. The Simpson`s index decreased from 0.65 on June 8 to 0.15 on November 10. Dominant weed species were Alopecurus aequalis Sosbol, and Polygonum hydropiper Spach in double cropping paddy field, but D. sanguinalis and P. oleracea were the dominant species in uplands. In reclaimed uplands various weed species including, 4rtemisia asiatica Nakai occurred almost equally. Average Simpson`s index for six crops studied was 0.40 and irrespective of the crops being cultivated P. oleracea and D. sanguinalis were dominant weed species and Y. hydropiper, C. album, Exolus blitum Grenier and E. canadensis were sub-dominant.
