Exploratory investigation of semantic reasoning in oneM2M
Nargis Khatoon,Naqqash Dilshad,JaeSeung Song 한국통신학회 2021 한국통신학회 학술대회논문집 Vol.2021 No.6
Today important challenges in the Internet of Things (IoT) include; providing interoperability among IoT data, interpreting data generated by IoT devices, and assisting developers in accomplishing these tasks by defining rules. Current standard development organizations such as oneM2M have a vital role to design the semantic-based IoT architecture to address such challenges. Semantic reasoning is introduced by oneM2M, which is a potential capability that oneM2M-compliant IoT instances have. This paper did an exploratory investigation of semantic reasoning in the oneM2M, which is a global initiative that develops specifications to ensure the most efficient deployment of Machine-to-Machine (M2M) communications systems and the Internet of Things (IoT)

<P>Species of genus Garcinia are rich sources of bioactive constituents with antimicrobial, anticancer, anti-inflammatory, hepatoprotective and anti-HIV activities. Commercial products of Garcinia cambogia are used as anti-obesity drugs with increasing market demand. Because of the high price of its products, it can be adulterated with similar lower-priced species. This study was designed to develop and validate an accurate and efficient method for the detection of any adulteration (G. indica) in G. cambogia products. For this purpose, high performance liquid chromatography (HPLC) was used to analyse the ethanolic fruit rind extracts of G. cambogia and G. indica, their formulations of 0.5, 1, 2, 5, 10, 20, 30, 40, 50, 60, 70, 80, 90 and 95% G. indica with G. cambogia, and 11 G. cambogia commercial products. The analytical methods were validated by quality assurance parameters of linearity, sensitivity, precision and accuracy. Two marker peaks were detected in G. indica fruit extract, whereas G. cambogia did not show these peaks. The detected peaks were identified as anthocyanins; cyanidin-3-O-sambubioside and cyanidin-3-O-glucoside. In the study to determine the effect of pH and temperature on the stability of its anthocyanin content, HPLC analysis of G. indica extract showed the highest content at pH 1 and 50 degrees C. Using two different mobile phases, the limits of detection (LOD) for cyanidin-3-O-sambubioside and cyanidin-3-O-glucoside were 0.036 and 0.059, and 0.022 and 0.033mgkg(-1), respectively. Furthermore, the inter-day precision (< 3.2%) confirmed that the applied analytical method fulfils the required criteria of Association of Official Analytical Chemists (AOAC). From this study, it was found that the HPLC method used for the detection of adulteration in G. cambogia products is rapid and accurate.</P>

Background: Breast illumination was suggested as a simple method for breast cancer screening. BreastLight is a simple apparatus for this purpose. Objective: To evaluate the diagnostic performance of BreastLight as a screening tool of breast cancer in comparison to mammography and histopathology. Materials and Methods: This hospital-based cross sectional study was conducted in the mammography unit of the radiodiagnosis department at National Cancer Institute, Cairo University. All participants were subjected to breast examination with the BreastLight tool, mammography and ultrasonography. Suspicious cases were biopsied for histopathological examination which is considered as a gold standard. Results: The mean age of the participants was $46.3{\pm}12.4$ years. Breast illumination method had sensitivity, specificity, positive predictive value, negative predictive value and total accuracy of 93.0%, 73.7%, 91.4%, 77.8% and 88.2%, respectively in detection of breast cancer. Conclusions: Breast illumination method with BreastLight apparatus is a promising easy-to-use tool to screen for breast cancer suitable for primary health care physician or at-home use. It needs further evaluation especially in asymptomatic women.

마이크로파이넨스 지원정책은 경제성장 및 빈곤완화를 위한 정책적 도구로 활용되고 있다. 이러한 중요성에 따라 그간 학계에서도 마이크로 파이넨스에 대한 이론적, 사례적 연구를 수행하여 왔다. 그러나, 그간의 연구들은 마이크로파이넨스에 대한 개념적 접근과 개별적 특성에 초점을 맞추어 온 관계로 이론과 프랙티스의 종합적 논의가 부족했고, 특히 마이크로파이넨스 시스템의 한계에 대해서는 관심이 미흡하였다. 이러한 문제의식에 따라 본 연구에서는 마이크로파이넨스의 대표적 사례인 방글라데시 그라민 은행의 성공 및 내재적 한계를 그간의 학술문헌과 최신 데이터를 이용하여 종합적으로 분석하였다. 주요 내용을 요약하면 다음과 같다. 그라민 은행의 대출제도는 일반 상업은행과는 반대의 형태로 운영되어 대출자의 자산이 많을수록 대출받는 금액이 큰 일반 상업은행과 달리, 그라민 은행은 대출자의 자산이나 소득이 적을수록 더 많은 대출이 가능하도록 설계되어 있다. 둘째, 그라민 은행의 성공은 혁신, 엄격한 감시통제 구조, 적응 및 학습, 인센티브 시스템 등의 복합적 요소의 결합에 의해서 가능하였다. 반면 그라민 은행 역시 금융시스템의 한 형태인 관계로 신용리크스는 내재적 리스크로 작용하고 있으며 빈곤 문제 해결에 대해 과대포장되었다는 비판도 제기된다. 그러나 분명한 것은 마이크로파이넨스 제도가 제도권 금융기관에서 자금을 융통하기 어려운 빈곤층의 금융수단으로서 작동해 왔으며, 지역사회의 빈곤문제는 물론 경제적 가치창출의 도구로서 기여한 것도 분명해 보인다. 향후 마이크로파이넨스의 건전성을 높이고, 대출자의 자립을 지원하기 위해서는 단순 대출에 머물지 않고 대출자에 대한 자문과 사업중계 등의 부가적 서비스를 제공하는 것도 고려할 사항이다. Microfinance has been an important tool for the economic growth and poverty alleviation. But the success factors and risk factors have not been synthesized in academic literature. This article has paid attention to success factors and potential risk of the Grameen Bank. Grameen Bank methodology is almost the reverse of the conventional banking methodology. Conventional banking is based on the principle that the more you have, the more you can get. Founder of Grameen Bank, Professor Yunus pointed out that, "The least you have the highest you have the priority to receive a loan". On the basis of theoretical literature, there have been different kinds of success factors of microfinance observed in this paper. Key success factors of Grameen Bank are like these: innovation, strict administrative structure, adaptation and learning practice, incentive system. Complementary services such as business consulting and brokerage will contribute to borrowers' economic performance development.

1-Hydroxy-2-methyl-2-(E)-butenyl-4-diphosphate reductase (HDR) or isopentenyl diphosphate synthase (IDS) is an enzyme at the final step of the MEP pathway. The multi-copy nature of IDS gene in a gymnosperm Ginkgo biloba is known. To evaluate the function of each isogene, the roles of the promoters were examined in Arabidopsis model. Among the promoters of GbIDS series, about 1.3 kb of GbIDS1pro and 1.5 kb of GbIDS2pro were cloned and fused with GUS. The GbIDS1pro::GUS was introduced into Arabidopsis to show GUS expression in most organs except for roots, petals, and stamina, whereas the GbIDS2pro::GUS was expressed only in the young leaves, internodes where the flower and shoot branched, and notably in primary root junction. This pattern of GUS expression correlated with high transcript level of GbIDS2 compared to that of GbIDS1 in Ginkgo roots. Methyl jasmonate (MeJA) treatment resulted in down-regulated GbIDS1pro activity in Arabidopsis leaves and upregulated GbIDS2pro activity in roots. The same pattern of gene regulation in roots was also seen upon treatments of gibberellins, abscisic acid, and indole butyric acid.
