  • This study aims to investigate the impact of the Corona pandemic on the earning quality (EQ) of Saudi national banks. It was conducted to evaluate the measurement of the earning quality based on the Penman approach. The researchers used the analytical method to conduct the study to find the effect of this Pandemic. Data was collected from the annual reports for the period 2010 to 2020 from Saudi national banks, which are twelve according to the annual report for the Saudi central bank, and eight of them were selected as a sample of the study. The banks are Alinma Bank, Al Rajhi Bank, Bank Al Bilad, The National Commercial Bank, Bank Aljazeera, Riyad Bank, Samba Financial Group (Samba), and Arab National Bank. The study findings showed that the Corona pandemic had a negative impact on the Saudi economy, and led to deflation in 2020 by 4.1% due to the oil sector. They also showed reducing oil production by the (OPEC +) agreement to achieve stability in the oil market and the non-oil sector. It was also revealed that the profits of Saudi commercial banks in 2020 decreased by 23.1% and that the Corona pandemic had Caused the earning quality to decline in all the studied banks.

  • The purpose of this study is to analyze the operation situation & academic research trends in Seoul and Gyeonggi area, based on theoretical consideration on academic credit bank system, focusing on academic credit bank system where a lifelong education institute affiliated with a university produces graduates with associate's degree. To find out about how academic credit bank institutes are operated in cosmetology field, the analysis of literature review was used, in reference to the literatures as well as administrative data from the Ministry of Education and institutes for lifelong education with respect to academic credit bank system. Further, dissertations and articles in journals were also reviewed for analysis, in order to see academic research trends with respect to academic credit bank system in cosmetology, and finally to provide the directions for a follow-up study in the future. It was found that about 120 junior colleges have cosmetology departments, while only about 20 4-year universities have them, where lifelong education systems such as lifelong education are essential for learners to have bachelor's degree to go to a graduate school in reality. Every year more people want to learn and acquire the degree through a lifelong education institute affiliated with a university. In this regard, it is thought that there should be first positive social awareness towards a degree recipient from such educations and more administrative promotion and active engagement of government, businesses and schools, in order to vitalize academic credit bank system. Meanwhile, there are only about 10 academic literatures including the dissertations on the operation of academic credit bank system with respect to cosmetology, which is not sufficient number in academic research, compared to the increasing number of people who want to acquire the degree. Most of the preceding studies have been limited to education services and learners' satisfaction level. Therefore, continuous follow-up study is required on how to improve social awareness as well as teachers and instructors' satisfaction level, as well as how to develop industry-customized curriculum, in order to ensure active academic credit bank system.

  • A peroxiredoxin cDNA (PgPrx) was isolated and characterized from the leaves of Panax ginseng. The cDNA is 716 nucleotides long and has an open reading frame of 489 base pairs with a deduced amino acid sequence of 162 residues. The calculated molecular mass of the mature protein is approximately 17.4 kDa with a predicted isoelectric point of 5.37. A GenBank BlastX search revealed that the deduced amino acid sequence of PgPrx shares a high degree homology with type II peroxiredoxin (Prx) proteins in other plants. The PgPrx gene was highly expressed in leaves, and expressed at a low level in the stem. To analyze the gene expression of PgPrx in response to various abiotic stresses, we utilized real-time quantitative RT-PCR. Our results reveal that PgPrx expression is induced by ultraviolet irradiation, low temperature, and salt. The induction of PgPrx in response to abiotic stimuli suggests that ginseng Prx may function to protect the host against environmental stresses.

  • Sesquiterpenes are found naturally in plants and insects as defensive agents or pheromones. They are produced in the cytosolic acetate/mevalonate pathway for isoprenoid biosynthesis. The inducible sesquiterpene synthases (STS), which are responsible for the transformation of the precursor farnesyl diphosphate, appear to generate very few olefinic products that are converted to biologically active metabolites. In this study, we isolated the STS gene from Panax ginseng C.A. Meyer, designated PgSTS, and investigated the correlation between its expression and various abiotic stresses using real-time PCR. PgSTS cDNA was observed to be 1,883 nucleotides long with an open reading frame of 1,707 bp, encoding a protein of 568 amino acids. The molecular mass of the mature protein was determined to be 65.5 kDa, with a predicted isoelectric point of 5.98. A GenBank BlastX search revealed the deduced amino acid sequence of PgSTS to be homologous to STS from other plants, with the highest similarity to an STS from Lycopersicon hirsutum (55% identity, 51% similarity). Real-time PCR analysis showed that different abiotic stresses triggered significant induction of PgSTS expression at different time points.

  • This study was undertaken to determine the complete mitochondrial DNA sequence and structure of the mitochondrial genome of Spirometra ranarum, and to compare it with those of S. erinaceieuropaei and S. decipiens. The aim of this study was to provide information of the species level taxonomy of Spirometra spp. using the mitochondrial genomes of 3 Spirometra tapeworms. The S. ranarum isolate originated from Myanmar. The mitochondrial genome sequence of S. ranarum was compared with that of S. erinaceieuropaei (GenBank no. KJ599680) and S. decipiens (GenBank no. KJ599679). The complete mtDNA sequence of S. ranarum comprised 13,644 bp. The S. ranarum mt genome contained 36 genes comprising 12 protein-coding genes, 22 tRNAs and 2 rRNAs. The mt genome lacked the atp8 gene, as found for other cestodes. All genes in the S. ranarum mitochondrial genome are transcribed in the same direction and arranged in the same relative position with respect to gene loci as found for S. erinaceieuropaei and S. decipiens mt genomes. The overall nucleotide sequence divergence of 12 protein-coding genes between S. ranarum and S. decipiens differed by 1.5%, and 100% sequence similarity was found in the cox2 and nad6 genes, while the DNA sequence divergence of the cox1, nad1, and nad4 genes of S. ranarum and S. decipiens was 2.2%, 2.1%, and 2.6%, respectively.

  • Since heat exchangers are composed of bank of tubes, the knowledge on the flow and heat transfer characteristics of the tube bank are required for the optimum design and selection of heat exchangers. In this paper, the turbulent flow fields and heat transfers normal to a staggered tube bank are solved numerically employing K-.epsilon. 2 equation turbulence model and non-orthogonal coordinate transformation for the treatment of curved surface of tubes. Predicted mean Nusselt numbers of tube bank agree reasonably well with Grimision's correlation

  • Historically, the en-users' acceptance of the expert systems(ES) have generally been used as a proxy for the ES' implementation success by both practitioners and academicians. However, with regard to bank loan decisions, most loan officers approach the acquisition of an ES with apprehension. In order to overcome this skepticism, more research should focus on the behavioral aspects relate to systems acquisition and usage. This research applied Vroom's(1964) expectancy theory in an effort to predict end-users' motivation to use an ES in a bank loan decision context. Because human behaviors and judgements are nonlinear rather than linear functions, accurately predicting human behavior is very difficult. To increase the prediction power for end-users' motivation to use an ES in a bank loan decision context, this research used an artificial neural network (ANN) model. In this research, an attempt was made to evaluate adequacy of the surrogates by analyzing differences between real bank loan officers and student surrogates in applying expectancy theory to estimate bank loan officers' motivation to use ES in a bank loan decision context.

  • 한국어 의미역 결정(Semantic Role Labeling)은 주로 기계 학습에 의해 이루어지며 많은 말뭉치 자원을 필요로 한다. 그러나 한국어 의미역 결정 시스템에서 사용되는 Korean PropBank는 의미역 부착 말뭉치와 동사 격틀이 영어 PropBank의 1/8 수준에 불과하다. 따라서 본 논문에서는 한국어 의미역 결정 시스템을 위해 의미역 부착 말뭉치와 동사 격틀을 확장하여 Korean PropBank를 확장 시키고자 한다. 의미역 부착 말뭉치를 만드는 일은 많은 자원과 시간이 소비되는 작업이다. 본 논문에서는 도메인 적응 기술을 적용해보고 기존의 학습 데이터를 활용하여, 적은 양의 새로운 학습 말뭉치만을 가지고 성능 하락을 최소화 할 수 있는지 실험을 통해 알아보고자 한다.
