Dong‑Geun Seo,Jeong‑Soo Park,Gun ‑Ki Lee,Wang‑Sang Lee 대한전기학회 2020 Journal of Electrical Engineering & Technology Vol.15 No.4

In this paper, a lightweight printed dipole antenna array with 3×2 beamforming network for wide unmanned aerial vehicle (UAV) communication coverage is presented. The proposed antenna consists of an upper substrate, a lower substrate, and two supports with a microstrip feeding. The upper substrate has a two-element printed dipole antenna array, and the lower substrate includes a beamforming feeding circuit and a ground plane as a refector of the proposed antenna array for gain improvement. For wide beam coverage, the proposed feeding network consists of three RF switches, one Wilkinson power divider, and one 90° hybrid coupler, and generates the wide beam using one broadside beam and two end-fre beams. Measured impedance bandwidth, peak gain, and half-power beamwidth (HPBW) of the proposed array operated from 5.03 to 5.15 GHz are approximately 2 GHz, 4.3 dBi, and 155°, respectively.

북한 과학환상소설에 나타난 사회주의 낙원과 역사적 조건들 -김동섭의 「바다에서 솟아난 땅」을 중심으로-

북한의 과학환상문학은 1950년대 말부터 등장하기 시작했다. 전후복구사업과 사회주의 국가 건설을 위해서 과학기술의 도움은 필수적이었다. 실재 북한은 과학기술에 많은 지원을 했으며, 이는 천리마운동을 통해 더욱 확산되었다. 김동섭의 ?바다에서 솟아난 땅? 역시 이러한 배경 속에서 탄생하였다. 어린이 잡지인 ??아동문학??에 1964년 6월부터 11회 연재된 이 작품은 사회주의 낙원을 건설하기 위해 바다 속의 땅을 육지로 만드는 과정을 보여주고 있다. 그 과정을 통해 천리마운동의 기술혁명, 사상혁명을 구현하고 있다. 유토피아 지향성은 자립경제의 열망과 연결되어 있으며, 이를 실현할 천리마 기수는 당시 ‘붉은 과학자’의 모습으로 그려지고 있다. 특히 어린이로 표상되는 새로운 세대와 구세대의 대조는 세대론의 시각을 넘어서고 있다. 이는 새 것과 낡은 것, 진보와 보수 등을 함의하고 있으며, 결국 새로운 사회주의 국가는 새로운 세대에 의해 이루어져야 함을 강조하고 있다. In North Korea, North Korean Science Fiction began to appear from the end of the 1950s. The help of scientific technology was essential for the restoration project before and after the war, and for constructing a socialist nation. In reality, North Korea has supported scientific technology in many aspects. This was reinforced further through Chollima Movement. Kim Dong-seop’s “Land Surging from the Sea” was produced under this background. This work, which had been published serially 11 times from June in 1964, in children’s magazine Children’s Literature, is showing the process of making the ground in the sea as the land in order to construct paradise of socialism. Through the process, it is implementing the technical revolution and the ideological revolution. The orientation toward utopia is deeply connected with a burning desire for independent economy. A flag bearer of Chollima, who will realize this, is being depicted as the image of ‘red scientist’ at that time. Especially, the contrast between new generation, which is represented by children, and old generation, is surpassing the sight of generational theory. This is suggesting the new & the old and the progress & conservatism. Ultimately, the new socialist nation is being emphasized to be necessarily accomplished by new generation.

Prevalence of infectious agents, including Brucella abortus (BA), Mycobacterium bovis (MB), bovine leukemia virus (BLV), M. avium subsp. paratuberculosis (MP), Neospora caninum (NC) and Toxoplasma gondii (TG), was investigated in all the cattle raised in Ulleung island during 2007∼ 2010. For BA, the prevalences in head and farm were 8.1% (44/545) and 5.5% (4/73) in 2007, all negative in 2008∼2009, and 0.5% (4/774) and 1.7% (1/58) in 2010, respectively. For MB, no sample was positive by PPD or ELISA in 2007∼2010. For BLV and MP, no sample was positive by ELISA in 2007∼2009. For NC, seroprevalences in head and farm were 0.2% (1/545) and 1.4% (1/73), respectively, in 2007 and all negative in 2008∼2009. For TG, seroprevalences in head and farm were 17.6% (97/552) and 54.8% (34/62) by ELISA in 2009. By regions, the seroprevalences of TG in Ulleung-eup, Seo-myeon and Buk-myeon were 26.0%, 9.8% and 16.7%, respectively, which had significant differences (P<0.0001). Tiger cattle were more resistant to TG infection than Hanwoo. The seroprevalence of TG in summer was higher than in autumn. The seroprevalence of TG in cows was higher than in oxen. The seroprevalence of TG in cattle was increased with age. In conclusion, this study indicates that the prevalences of six infectious diseases, except for TG which are widely spread, are relatively low in cattle reared in Ulleung island.

Various medicinal fungi have been traditionally used in many countries for health maintenance, as well as for the prevention and treatment of various diseases. Dong-Chong-Xia-Cha in Chinese, which translates as “winter worm and summer grass”, is an entomogenous fungus that colonized the larvae or pupae of insect. Although various biological activities of crude extracts have been reported, the precise active compounds responsible for the anticancer activities of cultured Cordyceps are not well defined. Therefore, as part of our study program to identify potential anticancer agents from traditional medicines, we used cordycepin isolated from Cordyceps militaris obtained by submerged cultivation. The aim was to isolate the pure cordycepin from the extracts of Cordyceps militaris and evaluate its anticancer properties. Silica gel column chromatographic purification of Cordyceps militaris extracts resulted in the isolation of cordycepin. The isolated cordycepin and crude cordyceps were examined for their anti-proliferative effects on human cancer cell lines, HCT, MC5-7, U-87MG, AGS, A549, and MCF-7 cells were analyzed. The isolated cordycepin displayed potent growth inhibition on HCT, MC5-7, U-87MG, AGS, A549, and MCF-7 cells with IC50 values of 86.16, 28.13, 282.40, 78.41, 137.40, and 216.40 μg/ml, respectively. A similar inhibitory trend in these cancer cells was observed for crude cordyceps, with IC50 values ranging from 60.8 317.2. The present study provides scientific supporting information for the ethnopharmacological use of Cordyceps militaris as an anticancer agent.
