  • The main objective of this study was to investigate the impact of access to finance on the different dimensions of poverty. To achieve the objectives of the study, the participants/beneficiaries of the Mudra scheme were included and sample of target respondents was extracted through multistage random sampling technique. The sample for the study was taken from the Union Territory of Jammu and Kashmir of India. The study further utilized secondary data from the government official websites and lead banks. A paired t-test was applied to test the impact of access to finance across the various dimensions of poverty by constructing the Multidimensional Poverty Index(MPI), after checking the normality of the data. MPI incorporates dimensions such as education, health, and standard of living.The finding of the study revealed that dimensions of poverty responded positively to access to finance. The study shows that larger access to finance has helped in reducing the multidimensional poverty by having moderate, but positive impact on the standard of living, health, and education, thereby improving the lives of the poor. The present study identified that the level of impact of access to finance is moderate and further explains its importance for policy implications.

  • 본 연구는 기대 교통사고건수 추정을 위해 사용되는 SPF의 이질적 분산계수의 유의성이 이질적 사전분포에 직접적인 영향을 받는다는 가설을 검증하고, 이질적 사전분포에 대한 모형 오설정이 교통 안전개선 사업의 평가결과에 주는 영향의 특성을 분석하기 위해 수행되었다. 구체적으로 본 연구에서는 이질적 분산계수의 유의성과 이질적 사전분포의 연관성을 검증하기 위해 모의실험을 통해 이질적 사전분포를 발생시킨 후 이를 NB모형과 HNB모형을 이용하여 SPF를 추정하여 이질적 과분산계수가 SPF의 평균함수 및 분산함수에 주는 영향을 분석하였다. 또한 추정된 계수추정치를 이용한 사전분포의 초모수 추정치의 오차특성과 이질적 과분산계수를 고려하지 않았을 경우 발생하는 교통사고감소계수(CRF)의 오차 부호와 크기를 상세 분석하여 제시하였다. 모의실험 자료 분석결과 이질적 분산계수의 오추정은 포아송 사전분포의 평균에는 큰 영향을 주지 않으나 분산의 크기를 변화시켜 궁극적으로는 기대교통사고건수의 추정량인 사후평균의 값에 오차를 발생시킬 수 있으며, 구체적으로 이질적 분산함수를 NB모형으로 오설정할 경우 CRF의 값은 참값에 비해 최대 120%의 오차를 발생시키는 것으로 나타났다.

  • New ITO thin film of good performance has been developed by brand-new, plasma-damage-free sputtering process at the room temperature. The room temperature-processed ITO films with optimized conditions as neutral beam acceleration bias of -30V and In & Sn composition ratio of 99:01 gives lower resistivity as $4.22{\times}10^{-4}{\Omega}-cm$ and higher transmittance over 90% a wavelength of 550 nm. The transmission electron microscope (TEM) images of the films show a nano-crystalline structure.

  • This study was carried out in degraded and non-degraded community forests (CF) in the Terai region of Kanchanpur district, Nepal. A total of 63 concentric sample plots each of 500 ㎡ was laid in the inventory for estimating above and below-ground biomass of forests by using systematic random sampling with a sampling intensity of 0.5%. Mallotus philippinensis and Shorea robusta were the most dominant species in degraded and non-degraded CF accounting Importance Value Index (I.V.I) of 97.16 and 178.49, respectively. Above-ground tree biomass carbon in degraded and non-degraded community forests was 74.64±16.34 t ha-1 and 163.12±20.23 t ha-1, respectively. Soil carbon sequestration in degraded and non-degraded community forests was 42.55±3.10 t ha-1 and 54.21±3.59 t ha-1, respectively. Hence, the estimated total carbon stock was 152.68±22.95 t ha-1 and 301.08±27.07 t ha-1 in degraded and non-degraded community forests, respectively. It was found that the carbon sequestration in the non-degraded community forest was 1.97 times higher than in the degraded community forest. CO2 equivalent in degraded and non-degraded community forests was 553 t ha-1 and 1105 t ha-1, respectively. Statistical analysis showed a significant difference between degraded and non-degraded community forests in terms of its total biomass and carbon sequestration potential (p<0.05). Studies indicate that the community forest has huge potential and can reward economic benefits from carbon trading to benefit from the REDD+/CDM mechanism by promoting the sustainable conservation of community forests.

  • Artemisinin resistance (ART) has been confirmed in Greater Mekong Sub-region countries. Currently, C580Y mutation on Pfkelch13 gene is known as the molecular marker for the detection of ART. Rapid and accurate detection of ART in field study is essential to guide malaria containment and elimination interventions. A simple method for collection of malaria-infected blood is to spot the blood on filter paper and is fast and easy for transportation and storage in the field study. This study aims to evaluate LAMP-SNP assay for C580Y mutation detection by introducing an extra mismatched nucleotide at the 3' end of the FIP primer. The LAMP-SNP assay was performed in a water bath held at a temperature of 56℃ for 45 min. LAMP-SNP products were interpreted by both gel-electrophoresis and HNB-visualized changes in color. The method was then tested with 120 P. falciparum DNA from dried blood spot samples. In comparing the LAMP-SNP assay results with those from DNA sequencing of the clinical samples, the 2 results fully agreed to detect C580Y. The sensitivity and specificity of the LAMP-SNP assay showed 100%. There were no cross-reactions with other Plasmodium species and other Pfkelch13 mutations. The LAMP-SNP assay performed in this study was rapid, reliable, and useful in detecting artemisinin resistance in the field study.

  • The present study was carried out to evaluate the chemical properties of soil in relation to forest structure and composition at different altitudes (900-2,600 m asl) in a part of Western Himalaya. The composite soil samples were taken from three (viz. upper, middle and lower) depths. The soils of the whole study area were acidic in nature (pH=4.90-5.51). Contents of Nitrogen (N), Phosphorus (P), Potassium (K), Carbon (C) and soil organic matter (SOM) showed much fluctuation during different seasons of year. Nitrogen content showed significant positive correlations with altitude (r=0.924, p<0.05) and different community parameters like species diversity (r=0.892, p<0.01) and species richness (r=0.941, p<0.05). Phosphorus exhibited direct correlations with carbon (r=0.637) while weak negative correlations with different community parameters like species richness & diversity, total basal cover (TBC), density and canopy cover. Carbon content and hence SOM showed direct correlations with Nitrogen (r=0.821, p<0.01); Phosphorus (r=0.637, ns) and Potassium (r=0.540, ns). But no significant relationship was observed between K content and species richness (p=0.30, r=-0.504); between K content and species diversity (p=0.14, r=-0.672); between P content and species diversity (p=0.29, r=-0.513) and species richness (p=0.23, r=-0.575). Among the different soil nutrients, only N showed a significant positive correlation with altitude while all others exhibited negative (but non-significant) correlation with it. The study revealed that the chemical properties affect and are reciprocally affected by forest structure and composition and that N rich soils of higher altitudes are best for the growth and development of forests.

  • In this study, we developed a loop-mediated isothermal amplification (LAMP) with hydroxynaphtol blue dye (HNB) for rapid and direct visual detection of porcine circovirus 2 DNA with high sensitivity and specificity. The LAMP was completed in 40 min at $63^{\circ}C$, and the results of the LAMP can be confirmed by naked eye without any detection process. The sensitivity of the LAMP was 10-fold higher than that of the commercial PCR (cPCR) and real time PCR (rPCR) previously reported. In clinical application, the PCV2 detection rate of the LAMP was the same on porcine tissue samples (75.0%, 36/48) between porcine blood samples (75.0%, 39/52). The PCV2 detection rate (75.0%) of LAMP was higher than those of the cPCR and rPCR (67.3%, 35/52) in blood samples. In conclusion, the LAMP developed in the study could be an useful alternative method for the detection of PCV2 in the swine disease diagnostic laboratories.

  • 바이로이드는 매우 작은 RNA 분자로 구성되어 있으며, 외피 단백질이 없고 오로지 식물에만 감염되어 질병을 유발한다. 바이로이드 감염 질병을 예방하거나 진단하는 것은 상당히 어려운 일이며, 이는 병징이 초기에는 발견되지 않고 수확기에 접어들어서 발견되기 때문이다. 한편, 혈청학적인 방법은 식물 병원체를 검출하기 위해 주로 사용되었으나 바이로이드는 핵산인 RNA로만 구성되어 있기 때문에 이 방법으로 검출할 수가 없다. 때문에 바이로이드를 검출하기 위해 주로 사용되는 방법은 분자 생물학적인 방법으로, 초기에는 바이로이드의 분자적인 크기와 구조적 특징을 이용한 겔 전기 영동 방법이 주로 사용되었다. 그 후에는 역전사 반응과 중합효소 연쇄반응을 접목시킨 역전사 중합효소 연쇄반응(RT-PCR) 방법이 활용되었고, 그에 대한 효율적인 결과 확인을 위해 형광 물질을 도입한 실시간 역전사 중합효소 연쇄반응(Real-time RT-PCR)이 도입되었다. 그러나 그들은 온도를 변화시키기 위한 값비싼 기기와 전문적인 인력이 필요함으로 현장에서는 활용되기가 어렵다. 최근 개발된 고리 기반의 등온 증폭법(Loop-mediated isothermal amplification)의 경우, 온도의 변화가 필요 없어 비싼 온도 조절 기기가 필요하지 않다. 또한 매우 높은 증폭 효율을 지니며 반응 시간이 짧은 등의 여러 장점을 지니고 있기에 최근 현장 진단용 기술에 도입되고 있다. 이러한 배경으로, 이 총설에서는 바이로이드 유발 질병에 대하여 요약하고 그에 대한 검출 및 진단 방법에 대한 연구 동향에 대하여 기술하였다.
