현재 유전자 변형 작물의 검정에는 CaMV 35S프로모터 혹은 NOS 터미네이터 등과 같이 형질전환에 널리 이용하는 유전인자를 검출하기 위한 PCR 기술이 널리 이용되고 있다. 본 연구에서는 유전자변형 감자를 검정하기 위한 새로운 기술로서 감자특이 internal control과 CaMV 35S 프로모터 혹은 NOS 터미네이터에 특이적인 프라이머를 이용한 경쟁적 이중PCR 방법을 개발하였다. 감자 유전자의 RAPD 결과 이용한 모든 품종에서 약 530 bp인 homozygous DNA 밴드를 증폭하는 특이 primer (rAGU4A)를 찾아 감자특이 internal control 증폭용으로 이용하였다. 이 프라이머에 의해 증폭되는 DNA는 TC 염기의 반복 빈도가 높은 repetitive 혹은 microsatellite DNA (AF541972)로 판단되었다. 이와 같은 단일 프라이머 internal control 증폭용으로 이용한 경쟁적 이중 PCR은 비특이적 PCR 산물을 줄일 수 있고, 기존 방법들에 비해 경제적이다. 현재 상품화되어 있는 유전자 변형 감자품종인 'New Leaf'의 경우도 형질전환에 이용한 유전인자로 CaMV 35S 프로모터와 NOS 터미네이터가 모두 이용되었으므로 이 기술을 이용할 경우 현재까지 상품화된 유전자 변형감자들의 효율적인 검정 기술로 이용될 수 있을 것으로 기대된다.

A leaf spring, especially the longitudinal type is liable and persistent element in automotive suspension system. In the present scenario the composite materials are widely used in the automobile industries has shown a great interest in the replacement of steel spring due to high strength by weight ratio. Previous investigations focused on stresses and displacement analysis of single leaf spring for different materials. The present work aims to design and analysis of leaf spring for two different cases by considering the Young's modulus to yield strength ratio. In the first case the analysis deals with the design and analysis of a single cantilever solid triangle beam which is an equivalent beam of a spring with three leaves having uniform strength. In the second case a 3-beams of rectangular cross section has been considered which is equivalent to a spring with three leaves. The analysis was carried out based on contact mechanics approach. The results were compared, that the fiberglass composite leaf spring is suitable for high loading capacity, reliability and efficiency.

The purpose of the paper is to explore the country-of-origin (COO) influence on the buying decisions of the United Arab Emirates (UAE) consumers. The collected data from 370 consumers were summarized and coded by using Software R Studio and Microsoft Excel. The independent variables were analyzed and tested for their significant impact on the dependent variable, final buying decision of the product/service based on its country of origin. The selected hypotheses tested by administering the Kruskal-Wallis (K-W) hypothesis testing technique. The researchers identified that UAE consumers buying decisions influenced mainly by the country of origin of the products and services. The demographic variables like age, education, country of origin influential factors, country of choice was not displaying any significant impact on the buying decisions of consumers. The survey is limited to cover the general consumers of the country who are randomly selected from Dubai and Sharjah emirates. The study is beneficial to all the types of marketers, including domestic and international companies, who have plans to know the exact influence on consumers' buying decisions. The present research paper is original and provides empirical evidence on the country of origin's impact on the buying decisions of different products/services in the UAE.

Intestinal helminths and schistosomiasis among school children were investigated in an urban and some rural communities of Ogun State, southwest Nigeria. Fecal samples of 1,059 subjects (524 males, 535 females) aged 3-18 years were examined using direct smear and brine concentration methods between June 2005 and November 2006. The pooled prevalence of infection was 66.2%. Ascaris lumbricoides showed the highest prevalence (53.4%) (P < 0.001) followed by hookworms (17.8%), Trichuris trichiura (10.4%), Taenia sp. (9.6%), Schistosoma mansoni (2.3%), Strongyloides stercoralis (0.7%), Schistosoma haematobium (0.6%), and Enterobius vermicularis (0.3%). The prevalences of A. lumbricoides, hookworms, Taenia sp., S. mansoni, and S. stercoralis in the urban centre were similar (P > 0.05) to those in the rural communities. The fertile and infertile egg ratios of A. lumbricoides in the urban centre and the rural communities were 13: 1 and 3.7: 1, respectively. Each helminth had similar prevalences among both genders (P > 0.05). The prevalence of A. lumbricoides increased significantly with age (P < 0.001). The commonest double infections were Ascaris and hookworms, while the commonest triple infections were Ascaris, hookworms, and Trichuris. The study demonstrates the need for urgent intervention programmes against intestinal helminthiases and schistosomiasis in the study area.

TEMPO와 NaBr의 수준에 따른 쌀가루의 반응 특성을 조사한 결과, 반응시간은 TEMPO와 NaBr의 수준이 낮을수록 증가하였고, 수율은 TEMPO의 수준이 증가할수록 증가하였다가 다시 약간 감소하였으며 NaBr의 수준이 증가할수록 감소하는 경향을 나타내었다. 선택성은 NaBr의 수준이 증가할수록 감소하는 경향을 보였다. 이에 따라 반응시간, 수율 및 선택성을 고려하여 산화 쌀가루 제조를 위한 TEMPO와 NaBr의 적정 수준을 각각 0.9 mM과 44 mM/100 mM AGU로 결정하였다. 산화 반응을 통해 쌀가루의 물과 결합능력 및 점도가 증가하는 것으로 나타났으며, 산화 쌀가루 수용액은 의가소성 유체의 성질을 나타내었다. 산화 쌀가루로 일부 대체된 쌀가루 현탁액은 초기 점성 증가 온도가 낮아지고 최고 점도는 증가하였으며 setback은 감소하는 것으로 나타나, 산화 쌀가루의 첨가에 따른 쌀가루의 노화 지연 가능성을 보여주었다. 산화 쌀가루를 2% 첨가하고 가수량을 증가시켜 제조한 절편의 텍스처 특성을 평가한 결과, 저장에 따른 경도 증가 현상이 억제되는 것으로 나타났다. 따라서 산화 쌀가루를 절편에 첨가할 경우 노화가 억제되어 저장기간의 증진 효과를 기대할 수 있으리라 본다.
