이재묵 ( Lee Jae-mook ) 한국외국어대학교 글로벌정치연구소 2020 글로벌정치연구 Vol.13 No.2

본 논문은 21대 총선 유권자 의식조사 자료를 활용하여 사전투표에 참여한 유권자 집단의 사회경제적 배경 및 정치적 특징을 분석한다. 한국에서 사전투표제는 2013년 이래 유권자들의 투표편의 제고를 위해 전국단위 선거에 도입되었으며, 그간 학계를 중심으로 과연 사전투표제가 제도 도입의 취지대로 투표율 제고 효과가 있는가에 대한 논쟁이 있어왔다. 이번 21대 국회의원 선거에서는 제도 도입 이래 역대 최고의 사전투표율을 기록하였고, 전체 투표 참여자 대비 사전투표자의 비중이 그 어느 때 보다도 높았다. 본 논문의 분석 결과에 따르면, 21대 총선에서의 사전투표 유권자들은 다양한 측면에서 기권자들뿐만 아니라 당일 투표자들과도 뚜렷하게 구분되는 정치적 특징들을 보여주었다. 특히, 4.15 총선에서 사전투표에 참가한 유권자들은 당일 투표자들에 비해 이념적으로 진보적이며, 현 집권 세력에 대해 보다 긍정적 평가 경향을 갖고 있는 것으로 나타났다. 한편, 한국에서 사전투표제도가 안착되어감에 따라, 비단 투표율 제고 효과를 넘어서 앞으로 우리 사회가 심도 있게 다루어야 할 다양한 제도적, 정치적 과제들이 제기되게 되었는데, 결론에서는 이에 대한 간략한 논의들을 제공한다. This paper analyzes the socioeconomic background and political characteristics of the early voters who turned out before the exact election day by utilizing the original survey data for the 21st general election. In Korea, the early voting system has been introduced in national elections since 2014 to enhance voter convenience, and previous studies have been debating whether the new system will improve voter turnout as intended. In the 21st National Assembly elections, the early voting rate recorded the highest ever since the system was introduced, and the proportion of early voters among all the voters who turned out was higher than ever. And according to the analysis results of this paper, the early voters in the 21st general elections showed political features distinctly distinct from those of the day as well as abstentions in various aspects. In particular, early voters were more ideologically progressive than voters on the election day and tended to have a more positive assessment of the incumbent president Moon Jae-in. Meanwhile, as the early voting system was settled in Korea, various institutional and political tasks that our society should deal with in depth beyond the effect of raising voter turnout were raised, and the conclusion provides brief discussions on them.

Analyzing Public Opinion and Emotions Using Tweets and Online-Comments toward Candidates in 2017 South Korean Presidential Election

Na Kyeong Lee,Jae Mook Lee,Gidong Kim 한국학술연구원 2019 Korea Observer Vol.50 No.4

The 2017 Korean presidential election was different from previous presidential elections for two reasons: First, it was a by-election due to the unprecedented impeachment of the president Park Geun-hye, and second, more than three candidates from multiple parties competed in the election. Since Moon Jae-in was predicted to easily win, the fight for the second place - between Hong Joon-pyo and Ahn Cheol-soo - was very competitive. In order to understand the electoral dynamics, we collect and analyze tweets and online-comments toward major candidates with logic of granger causality. We find that public sentiment toward Ahn does Granger-cause changes in online sentiment toward other candidates both from major and minor parties. This result shows that Ahn played a pivotal role in the 2017 presidential election, and implies that Koreans are eager to have alternative forces.

Osteoporosis is a condition in which an imbalance appears between bone resorption and formation, with bone resorption exceeding formation. Recent studies have shown that bone formation abnormalities in various forms of osteopenia result mainly from defective recruitment of osteoblastic cells. These abnormalities in osteoblast function and bone formation are associated with alterations in the expression or production of several growth factors, such as TGF-β which modulate the proliferation and activity of bone-forming cells. Bone transplantation is an absoulte requirement in several patholigical conditions. The growth factors, such as TGF-β, PDGF, were the effective in promoting growth of the bone in vitro and in animal models. We have investigated the effects of PDGF and TGF-β on the proliferation and differentiation of the normal human osteoblast in vitro culture. The normal human osteoblast from iliac bone were primarily cultured. The serums obtained from the osteoporotic patients and the normal was used to quantify PDGF and TGF-β from the osteoporotic patients serum and the normal serum. To clarify the effects of the various different the culture conditions such as 1×10 exp(4) cells/㎖, 2.5×10 exp(4) cells/㎖, 5×10 exp(4) cells/㎖, 10×10 exp(4) cells/㎖ (0.2∼2×10 exp(4) cells/well) of the osteoblast at 24 hours, 48 hours, 72 hours under 10% FBS, 10% normal human serum, 10% osteoporotic human serum, 3% normal human PRP, 3% osteoporotic human PRP. The cell proliferation and differentiation was determined by [^3H]-thymidine and SRB assay, and the magnitude of differentiation to osteoblast was confirmed by von Kossa staining and alkaline phosphatase stain and measuring the alkaline phosphatase activity during 48 hours and 72 hours. Statistical differences were evaluated using the scheffe's test. The ANOVA procedure of the SAS system. The obtained results were as follows ; 1. The age distribution of normal human was 36.9±4.4 old, osteoporotic human was 72.5±0.2 old with statistical significant difference(p<0.05). 2. The quantification of TGF-β of the normal human serum was 39658.38±11630.43 pg/㎖, the osteoporotic human serum was 30459.40±1704.92 pg/㎖ with statistical significant difference. The quantification of PDGF of the normal human serum was 3064.13±709.51 pg/㎖, the osteoporotic human serum was 2514.13±140.21 pg/㎖ with no statistical significant difference(p<0.05). 3. The DNA synthesis and protein assay of human osteoblast at 24 hours, 48 hours, 72 hours was similar increased to 10% normal human seurm, 10% osteoporotic human serum. There was no statistical significant difference between the normal human and the osteoporotic patients in 3% normal human PRP and 3% osteoporotic human PRP. 4. The optimal cell concentration was 5×10 exp(4) cells/㎖ among 1×10 exp(4) cells/㎖, 2.5×10 exp(4) cells/㎖, 5×10 exp(4) cells/㎖, and 10×10 exp(4) cells/㎖. The DNA synthesis was decreased after 72 hours in the normal human serum and PRP, the osteoportic serum and PRP. 5. The alkaline phosphatase activity was as the same result 10% FBS, 10% osteoportic serum and 10% normal human serum at 48 hours with no statistical significant, but the alkaline phosphatase activity was increased in 10% osteoportic human serum and 10% normal human serum except 10% FBS at 72 hours. From above result, the amount of TGF-β of the normal human growth factor was higher than the osteoporotic patients, but the growth factors of the osteoportic patients were enough the proliferation and differentiation of normal human osteoblasts such like the same effects of normal human growth factors.

류완호,이원묵,홍필선,양천희,안재영,백일현,이병노 한국화학공학회 2003 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.41 No.5

석탄회를 이용, 중금속 제거용 흡착제 제조를 목적으로 NaOH를 반응물로 한 수열합성 반응으로 제올라이트를 합성하였으며, 이에 대한 성능특성 및 중금속 흡착실험을 수행하였다. SiO₂와 Al₂O₃를 주성분으로 한 석탄회를 NaOH에 의한 수열합성 반응으로 폐수 중에 포함되어 있는 중금속에 대한 제거능력이 높은 제올라이트를 합성하고자 하였다. 따라서 NaOH 농도, 시간을 변화시키면서 제올라이트를 합성하여 실험한 결과 4 M-NaOH, 4시간에서 최적의 조업조건을 얻을 수 있었다. 산에 의한 전처리 과정을 거친 합성 제올라이트는 pH 7-9.5로 중성을 나타내었다. 또한 산처리 합성 제올라이트를 이용하여 중금속인 P, Pb, Cd, Cr, Mn등의 흡착능을 비교한 결과 P, Pb, Cd 등은 비교적 흡착능이 우수하게 나타났지만 Cr과 Mn 등은 pH가 너무 높기 때문에 거의 흡착이 이루어지지 않았다. Zeolite was synthesized from coal fly ash produced by a domestic power plant and has applications in the removal of heavy metal from waste water. Zeolite was synthesized using a hydrothermal method involving an alkaline reaction with NaOH. The NaOH concentration and reaction times were varied in order to synthesize zeolite showing the maximum removal efficiency of heavy metal from waste water. The synthesis conditions were optimized at the concentration of 4M-NaOH and the reaction time of 4hn. The synthesized zeolite needed washing with HCI solution to improve the removal efficiency of P, Pb. Cd. Cr. Mn and it was maximized at pH 7-9.5 in leaching solution of synthesized zeolite.
