The purpose of this article is to review the changes of perspectives on the Third World development in development studies. Employing the Kuhnian concept of $quot;paradigm change', it explains the rise and fall of the mainstream Western development theory (Modernization theory) and Dependency theory respectively, and discusses the prospect of newly emerging paradigm-possibly Statist theory. Accordingly more attention is paid to the industrialization processes of East Asian NICs, which have been often referred to as the prominent counter instances of Dependency theory, with a view to discuss whether market intervention of the state would contribute to successful economic development in developing countries.

Foliar fertilization is a effective application method used in these uplands as it provides good nutrition and increases crop yields. To determine the effect of foliar fertilization with monopotassium phosphate (MKP) on growth and yield of sweet potato, we analyzed plant growth, microbial communities by fatty acid methyl ester and chemical properties in soils from MKP 0 (control), 1, 2, 3, 4, and 5% treatments. Soil pH significantly increased by increasing concentration of foliar fertilization with MKP. Compared with control, the soils of MKP 3% and 4% treatments had a significantly higher community of actinomycetes while the applications of KMP 4% and 5% was significantly decreased soil fungi communities. In addition, the MKP 4% had a significantly lower ratio of cy17:0 to 16:1w7c compared with other treatments, indicating that microbial stress decreased. The highest increase in productivity of sweet potato is reached with foliar fertilization of MKP 3% treatment and optimum concentration of MKP based on regression yield curve was 2.6%. These results indicate that foliar fertilization with MKP was more effect on the productivity of sweet potato.

The biodegradable film application can escape from plastic environmental pollution. This experiments studied the effect of biodegradable mulch film on the soil microbial community using fatty acid methyl ester method in soybean production field. The soil NO3-N content in polyethylene mulch film (PE) soil was significantly higher than biodegradable mulch film soil (p < 0.05). The soil microbial community of Gram negative bacteria showed significantly higher in biodegradable mulch film soil than PE mulch film soil (p < 0.05). In addition, biodegradable mulch film soil had significantly low ratio of cy17:0 to 16:1ω7c and cy19:0 to 18:1ω7c compared with those of PE mulch film soil (p < 0.05), indicating that microbial stress decreased. The ratio of cy17:0 to 16:1ω7c and cy19:0 to 18:1ω7c should be considered as a potential responsible factor for the obvious differentiation that was observed between the biodegradable mulch film soil and PE mulch film soil in a upland field. The results of this experimentation show the potential of using biodegradable mulch film in place of PE.

Fusarium wilt (Fusarium oxysporum) is responsible for damage or negative effect on sweet potato (Ipomoea batatas L.) cultivation. This study evaluated the effect of curing treatment on the growth of sweet potato and soil microbial communities using fatty acid methyl ester method. We utilized three treatment groups, control, curing treatment of cutting for a day (C1), and curing treatment of cutting for 5 days (C5). Soil chemical properties showed no significant effect for the treatments. The marketable root number per plant and yield of sweet potato in C5 treatment were significantly higher than those in control and C1 (p < 0.05), whereas the Fusarium wilt in C5 treatment showed significantly lower than that of the control and C1 (p < 0.05). In addition, Fusarium wilt showed significantly increase as increasing soil fungi biomass, while the yield of sweet potato was significantly decrease as increasing Fusarium wilt (p < 0.05). The soil of C1 and C5 had a significantly lower biomass and community of fungi when compared with that of control (p < 0.05). These results indicate that curing treatment of cutting was more effect on the prevention of Fusarium wilt as well as the productivity of sweet potato.

문진영,민병규,신정호,최용조,이용한,민성란,조현지 한국토양비료학회 2019 한국토양비료학회지 Vol.52 No.3

Growth and yield components of sweet potato (Ipomoea batatas L.) were investigated under 0, 25, 50, 75, and 100% application rates of soil test based fertilizer recommendation with 5.5 kg 10a-1 N, 10.1 kg 10a-1 P2O5, and 19.8 kg 10a-1 K2O under polyethylene mulch. Soil chemical properties showed no significantly increased by increasing application rates of fertilizer recommendation. The 75% and 100% treatments increased total fatty acid methyl ester (FAME), bacterial FAME, Gram-negative and –positive bacterial FAME, and fungal FAME. The soil of 75% treatment had a significantly lower community of Gram-positive bacteria compared with 0%, 25%, and 50% treatments. The marketable root number was significantly higher in fertilizer 25% and 75% treatments, whereas marketable root weight was significantly higher in fertilizer 50% treatment. The highest increase in productivity of sweet potato is reached with 75% fertilization (3,305 kg 10a-1) of fertilizer recommendation and optimum fertilizer rates based on regression yield curve was 80% fertilization of fertilizer recommendation. These results indicate that new soil test based fertilizer recommendation was more effect on the productivity of sweet potato as well as soil nutrient conservation under polyethylene mulch system

시분해 테라파 분광학을 이용한 고전도성 탄소나노튜브 박막의 광학계수 측정

문진영,박두재,임종혁,이상민,이순일,안영환,Moon, J.Y.,Park, D.J.,Lim, J.H.,Rotermund, F.,Lee, S.,Ahn, Y.H. 한국광학회 2010 한국광학회지 Vol.21 No.1

본 연구에서는 전도성이 매우 높은 탄소나노튜브 박막을 제작하고 테라파 영역에서의 광학상수를 측정하였다. 탄소나노튜브박막은 스핀코팅법 또는 진공여과법을 이용하여 연성플라스틱 기판 위에 증착되었다. 테라파 영역의 전자파 투과율은 박막의 두께조절을 통해 가능하며, 산처리 등의 후속공정을 통해서도 조절이 가능하다. 시분해 테라파 투과파의 진폭과 위상 측정을 통해유전상수를 포함한 광학상수의 스펙트럼을 측정하였다. 이를 통해 탄소나노튜브 박막이 Drude 자유전자 모델에 잘 부합하며, 높은 플라즈마 진동수를 가지는 등, 우수한 금속의 특성을 가지고 있음이 밝혀졌다. 또한 산처리 전후 유전상수가 변화하는 것을 직접확인할 수 있었다. 마지막으로 셀룰로즈 멤브레인에 증착된 CNT 필름의 경우엔 기판의 효과가 제거된 광학계수 측정이 가능함을 보여준다. We performed time-domain terahertz (THz) spectroscopy to determine optical constants of highly conductive carbon nanotube (CNT) films. The CNT films have been fabricated on a flexible plastic substrate by using spin-coating or vacuum filtration. We found that the transmission of THz waves can be controlled by manipulating the thickness of the films and by post-treatments. From amplitude and phase information of the transmitted THz waves, we obtain optical constants such as refractive indices and dielectric constants of the CNT films. The frequency dependent dielectric constants show good metallic behaviors, relevant to the Drude free electron models with high plasma frequencies. It is also found that the dielectric constants are higher for the acid-treated films. Finally, the frequency dependent dielectric constants which are free from substrate effects have been demonstrated by using CNT films deposited on cellulose membranes.

Effect of Indium Doping on the Electrical Properties of Solution-Processed Mg0.2Zn0.8O Thin Film Transis

문진영,이호성 대한금속·재료학회 2017 ELECTRONIC MATERIALS LETTERS Vol.13 No.3

We fabricated solution-processed thin film transistors (TFTs) with In-dopedMg0.2Zn0.8O channel layers and investigated the effect of In doping on thedevice performance. With increasing In content in the Mg0.2Zn0.8O films, theoff-current decreased and the threshold voltage shifted in the positivedirection. This was due to the reduction in carrier concentration caused by Inaddition. Disordered atomic arrangements such as stacking faults wereobserved with increasing In content in the Mg0.2Zn0.8O thin films. Suchstructural defects could generate localized acceptor states, leading to areduction in carrier concentration. These results suggest that In doping can bea useful technique to produce more reliable solution-processed Mg0.2Zn0.8Omaterials for TFTs and other applications.

최근 국제 석유 및 가스 수급 동향과 시사점: 주요 생산, 소비국을 중심으로

▶ 지난 2012년 11월 발표된 국제에너지기구(IEA)의 「세계 에너지 전망(World Energy Outlook 2012)」에 따르면 2020년 이후 미국이 주요 산유국을 제치고 세계 최대의 산유국으로 부상할 것으로 전망됨. ▶ 사우디아라비아와 러시아가 전체 석유 생산의 약 25%를 점유하고 있는 가운데, 석유 소비량은 개발도상국을 중심으로 증가 추세를 보이고 있고, 주요 아시아 국가(중국, 인도, 일본)의 대(對)중동 석유 수입 의존도는 40%를 상회함. ▶ IEA의 전망에 따르면 전 세계적으로 전통적인 석유 생산 비중이 줄고, 북미 지역을 중심으로 한 비전통적 석유 생산이 늘어나게 되며, 이에 따른 미국의 석유 수입량 감소가 개발도상국의 수요로 대체될 전망임. ▶ 미국은 2008년 이후 세계 최대 가스 생산국으로 부상하였는데, 셰일가스 개발 확대로 미국의 가스 생산은 2035년경에 2011년 대비 23% 증가할 것으로 전망됨. ▶ 우리나라는 에너지 수입 경로의 지정학적 위험 증가와 에너지 시장 역학관계의 변화에 대비하고, 산업부문에서 에너지 소비를 절감할 수 있는 동기부여 및 기술개발 지원이 필요함. ▶ 셰일가스 생산국뿐만 아니라 전통적인 생산국가와의 협력을 증진하고, 가스 사용 비중을 높여 온실가스 감축에도 대처하는 방안으로 활용해야 함.
