  • This study was performed in order to obtain basic data of macrobenthic community in continental shelf exclusive economic zone (EEZ), before sand excavation. The species number of macrozoobenthos was 157, mean density was 2,529 ind./$m^2$ and mean biomass was 231.8 $g/m^2$ in November, 2000. The species number of macrozoobenthos was 179, mean density was 3,773 ind./$m^2$ and mean biomass was 391.2$g/m^2$ in February, 2001. Dominant species were Ampelisca sp. and Photis sp. in amphipods, Ophiactis branchygenys in ophiuroids and Nothria sp. and Eunice sp. in polychaetes. In the proportion of feeding types of macrobenthos, surface deposit feeders were most dominant feeding group, and followed by carnivores, subsurface deposit feeders, and filter feeders. Species diversity index (H') was high ranging from 2.5 to 3.5 at most sites.

  • This study analyzed the changes in productivity growth of 291 regional fisheries cooperatives area from 2001 to 2010 selected as target. The productivity growth analysis of operating offices calculates Global-Malmquist productivity index. Input variables are number of the persons and the nettable area, output variables are deposit, loans and earnings. To improve the homogeneity of industry, the operating conditions were considered. Global Malmquist index of Operating offices was reduced between 2001~2010. The cause of increase and decrease of productivity are divided by efficiency change(EC) and best-practice change(BPC). Operating offices with increased productivity existed between 2001~2002 and between 2002~2003 and between 2006~2007. There were operating offices with increased productivity by EC. Global Malmquist index of Operating offices with locations was highest relatively in metropolitan. Operating offices with increased productivity existed between 2003~2004 and between 2007~2008 and between 2008~2009 in all locations. There were operating offices with decreased productivity by BPC.

  • The purpose of this study is to analyze the research trends of lifelong education workers, based on research articles related to lifelong education workers published in domestic journals from 2001 to 2021, and to provide basic data for future lifelong education workers research. In order to achieve these research objectives, research trends of 40 research articles related to lifelong education workers published in domestic journals were analyzed by research subject and research method, and the detailed research conclusions are as follows. First, as a result of the analysis by characteristics of researches related to lifelong education workers, it has been continuously increasing since 2001 out of a total of 40 articles by year. From 2001 to 2005, there were 2, 8 from 2006 to 2010, 10 from 2011 to 2015, and 20 from 2016 to 2021. By major publication, there were a total of 20 publications, including 8 Lifelong Education Studies, 5 Lifelong Learning Society, 4 Andragogy Today, and 3 HRD Studies, and 20 articles were published in non-mainstream journals. Second, as a result of the analysis of each study subject, there were 20 lifelong education history, 16 lifelong education managers, and 4 others. Third, as a result of analysis by research method, quantitative research was most used, followed by qualitative research, literature research, and mixed research. In future research, many research topics such as analysis of various policies related to lifelong education workers and exploration of development plans should be carried out.

  • Fish species composition and abundance in the waters of nearby Nakdong River estuary were investigated non-continuously and seasonally by shrimp beam trawl in summer 2007, winter 2009, and from spring 2010 to autumn 2010. During the study period, total fish species were collected 92 species, 36 families in study area. Shannon index was 1.893~2.962, and evenness was 0.050~0.231. Fish species composition was shown interannually and seasonally variations in the waters of nearby Nakdong River estuary. We carryed out cluster analysis to contain the data in previous and current study. Fish species composition was divided 3 groups which were 1987~1988 and 1998, 2001~2002, and 2007~2008 and 2009~2010. Average and minimum length in this study was longer than its in previous studies, and length range in this study was wider than its in previous studies, too. Dominant fish increased individuals and weight per unit area in this study. Especially Lophius litulon, Raja kenojei, Eopsetta grigorjewi, and Zeus faber were much better than past 2002. Liparis tanakai, Repomucenus valenciennei and Leiognathus nuchalis were dominant fish in previous study, but those decreased individuals and weight per unit area in this study.

  • This study aimed to understand temporal and spatial trends of rainfall characteristics in South and North Korea. Daily rainfall observed at the 65 stations in South Korea between 1963 and 2010 and the 27 stations in North Korea between 1973 and 2010 were analyzed. Rainfall Indicators for amount, extremes, frequency of rainfall were defined. Province-based indicators in the recent 10 years (i.e., between 2001 and 2010) were compared to those in the past (i.e., between 1963/1973 and 2000 for South/North Korea). In the recent 10 years, all the indicators except for the number of wet days (NWD) and 200-yr frequency rainfall (Freq200) increased in South Korea and all the indicators except for the annual mean daily rainfall over wet days (SDII) and annual total rainfall amount (TotalDR) decreased in North Korea. Furthermore, we performed the Mann-Kendall trend test based on the annual indicators. In some stations, decreasing trends in the past and increasing trends in the recent 10 years were found, and such opposite trends between two periods suggest he limitation in predicting and analyzing the rainfall characteristics based on the average. Results from this study can be used in analyzing the impact of climate change and preparing adaptation strategies for the water resources management.

  • The purpose of this study is to address a current mushroom export situation in Gyeongbuk area for establishing exports strategy, and policy of mushrooms export. Mushroom industry has made a rapid growth over the past 20 years in Korea. Gyeongbuk province exports volume of enoki and king oyster mushrooms account for about half of the country, enoki and total exports in 2009, and 81%, increased to 14% in 2010 and 2010, the maximum exports (9,415 tons) and the maximum exports (14,840 grand)was recorded. But, enoki and total exports in 2011, and -15%, decreased to -19% in 2012, and increased to 32% in 2013, 1% in 2014. King oyster mushroom to represent the Netherlands in Europe, exports were higher exports to China is negligible. In the case of China in 2001, 5 spots automated mushroom factory, production, but only 8,000 tons in 2011, 652 mushroom factory, production of 1,100,000 tons and in 2012, 788 mushroom factory, production of 1,520,000 tons quickly grew.

  • The purpose of this study is to analyze the effects of spatial characteristics, such as land cover and topography, on heat wave days from the city of Milyang, which has recently drawn attention for its heat wave problems. The number of heat wave days was calculated utilizing RCP-based South Korea climate data from 2000 to 2010. Land cover types were reclassified into urban area, agricultural area, forest area, water, and grassland using 2000, 2005, and 2010 land cover data constructed by the Ministry of Environment. Topographical features were analyzed by topographic position index (TPI) using a digital elevation model (DEM) with 30 m spatial resolution. The results show that the number of heat wave days was 31.4 days in 2000, which was the highest, followed by 26.9 days in 2008, 24.2 days in 2001, and 24.0 days in 2010. The heat wave distribution was relatively higher in agricultural areas, valleys, and rural areas. The topography of Milyang contains more mountainous slope (51.6%) than flat (19.7%), while large-scale valleys (12.2%) are distributed across some of the western region. Correlation analysis between heat wave and spatial characteristics showed that the correlation between forest area land cover and number of heat wave days was negative (-0.109), indicating that heat wave can be mitigated. Topographically, flat areas and heat wave showed a positive correlation (0.305). These results provide important insights for urban planning and environmental management for understanding the impact of land development and topographic change on heat wave.
