Ginseng (Panax ginseng CA. Meyer) hairy root cultures, which are established via the infection of ginseng root discs with Rhizobium rhizogenes, have been used to construct profiles of both biomass growth and nutrient consumption in flask cultures. In a 250 mL shake flask culture, the maximum biomass was observed on the 59th day of the culture period, at 216.8 g (fresh wt) per liter or 11.4 g (dry wt) per liter. The hairy roots were determined to have a growth rate of 0.355 g-DW/g cells/day during the exponential growth phase and a maximum specific growth rate on day 7. Total ginseng saponin and phenolic compound contents were noted to have increased within the latter portion of the culture period. Linear correlations between increases in biomass weight and nutrient uptake were used to imply the conductivity yield $2.60g-DW/(L{\cdot}mS)$ and carbon yield 0.45 g-DW/(g sugar) in the 250 mL flask cultures. The biomass yield when two different nitrogen sources were used (ammonia and nitrate) was shown to remain approximately constant. at $0.47g-DW/(L{\cdot}mM\;NH_4$) and $0.33g-DW/(L{\cdot}mM\;NO_3$); it remained at these levels for 16 days with the ammonia. and for 24 days with the nitrate. The biomass yield when a phosphate source was used was also shown to remain approximately constant for 9 days, at $3.17g-DW/(L{\cdot}mM\;PO_4$), with an $R^2$ of 0.99.

The detection process of defective tags in most of Korean domestic RFID manufacturing companies is handled or treated by on-hand processing after the job of chip bonding, so it has been requesting to reduce the time and cost for manufacturing of RFID tags. Therefore, in this paper, we design and implement the system to perform the functionality of detection of defective tags after the process of chip bonding, and so provide the basis of a related software to establish the foundation of a automation system for the detection of defected RFID tags which is requested in the related Korean domestic industrial field. The developed system in this paper shows the enhancement of 700% in processing speed and 100% in detection rate of defective tags, comparing to the method of on-hand processing.

Unlike previous studies, this study looked at the effect of the ideological tendencies of local government heads on the social welfare budget as a longitudinal study. This study was made possible by the election of the head of a progressive group in Gumi-si, a stronghold of conservatives, after the implementation of the local self-government system. Therefore, in this study, the change process of the political ideological orientation of Gumi-si's heads and the social welfare budget by year were listed and time-series analysis was conducted using actual cases of Gumi-si, Gyeongbuk for more than 12 years. As a result of the analysis, first, as in the cross-sectional analysis, in the longitudinal study, the change in the rate of increase in the social welfare budget according to the political ideological tendencies of the head of the local government showed a meaningful difference. Second, as in the previous cross-sectional analysis, the social welfare budget increased in the year before the election. Third, the same change in the growth rate as in the second did not appear at the end of the third elected term. All studies on the relationship between the political ideological tendencies of local government heads (including local councils) and the social welfare budget have been cross-sectional. However, this study has great implications in terms of the results of the first longitudinal cross-sectional analysis.

This study investigated the table settings used in Bul-chun-wi sacrificial rituals in Sangju, Gyeongpook Province. This study took place from May 2014 to April 2015 and incorporated field research and literature review. The subjects of the study were Sojae jongga (family head), Wolgan jongga, Ubook jongga and Ipjae jongga. There were four rows in the table setting of the Wolgan, whereas there were five rows in the other jonggas. In row 5, there were fruits, seeds and confections. In row 4, there were vegetables. In row 3, there was tang (stew); in row 2, juk (steamed meats or fishes) and pyun (rice cake); and in row 1, meh (boiled rice), geng (soup) and myun (noodles). The common food setting was arranged in the order of meh, geng, myun, ganjang (Korean soy sauce), poh (dried meat/fish), chimchae (water kimchi), dates, chestnuts, pears, persimmons, walnuts, bracken, bellflowers, croaker, pyun, and ssam (rice wrapped in lettuce leaves). Ubook jongga had the most number of stews at seven. Sojae and Ipjae jongga each had five stews, and Wolgan jongga had three. The smaller Wolgan jongga had gehjuk (boiled chicken), uhjuk (steamed fish) and yookjuk (boiled meat) arranged in a neat pile on one dish used for rituals, whereas Ubook jongga had gehjuk, uhjuk and yookjuk arranged separately. Sojae and Ipjae jongga had gehjuk arranged separately while yookjuk and uhjuk were arranged as dojuk (gehjuk, uhjuk, yookjuk). The uhjuk was arranged separately. In Wolgan jongga, po was arranged on the right while in the other jonggas, it was arranged to the left. For raw meat Ubook jongga, raw mackerel; Ipjae jongga, raw croaker, and Sojae jongga Yukhoe (beef tartare) were set. However, pork, chicken and croaker were cooked. Other ritual food were used in seasoning and boiling. In the geng Wolgan and Ipjae jongga used miyeokguk (seawood soup), whereas Sojae and Ubook jongga used tangguk (meat soup with vegetables). For the ritual food, most jongga ordered yoogwa, yakgwa and bonpyun as one part, rice cakes (steamed rice cake, glutinous rice cake, jeungpyun, gyungdan), and jehju (alcohol). The other ritual food was prepared on the day by jongga.
