  • The genes of Halohacteria. gvpD and gvpE. take part in formation of gas vesicle. These mRNA cause a lot of experimental prohlems due to its eharacteristic instahility in the analysis of transcripts. This study allowed easy cloning and sequencing of RNA hy substituting a stable complementary DNA for the mRNA of the genes for an analysis. The weak 111 RNA was reverse transcribed to DNA using reverse transcriptase. and was amplified using PCR method. The transcripts confirmed in this ~,tudy have not heen round in the northern hybridization covering almost all ranges of ORF of the gene. gvpD.

  • Fibrinolytic and fibrinogenolytic activities of the venoms from the Korean snakes, Agkistrodon caliginosus, nosus, Agkistrodon saxatilis and Agkistrodon blomhoffi brevicaudus were compared by fibrin-plate method and polyacrylamide gel electrophoresis, respectively. The venom from A. blomhoffi brevicaudus showed the highest degree of fibrin(ogen)olytic activity, and a protease with the fibrin(open)olytic activity was purified by p-amino-benzamidine affinity chromatography and DEAE ion-exchange chromatography. The purified enzyme had a molecular weight of 50,800 and a capability to degrade the B$\beta$-chain of fibrinogen preferentially to the $A\alpha$-chain, but not the ${\gamma}$-chain. Fibrinolytic activity of the purified enzyme was approximately 3.8 plasmin unit/mg protein.

  • The outbreak of a recent strain of Coronavirus, known as 'COVID-19', has spread sharply from China across the globe, resulting in a dramatic recession in the global economy. This uncertainty has therefore negatively influenced the business perspective and the various formulated strategies that may not considered such [extreme] circumstances. Using baseline analysis and archival data, this paper reports some of the major implications of COVID-19 on global business and strategy and puts forward suggested research agenda as potential future directions for organizations. In order to survive and remain sustainable, this paper argues that businesses need to revisit their strategies during current COVID-19 crises from three perspectives, including supporting human resources financial commitment, forming cross-functional teams and connecting with their supply chains, as well as investing in corporate social responsibility and doubling down efforts with regard to partnerships. The study also represents a preliminary analysis to the implications of COVID-19 on the business and strategies across the globe and is considered the first such in the field of business, as to date all research papers on COVID-19 have been published in medical-related journals. Directions for future research are also proposed at the end of this study.

  • We introduce about XBRL, eXtensible Business Reporting Language, which is widely accepted as the international standard language for business financial reporting. XBRL is a language for the electronic communication of business and financial data which is revolutionizing business reporting around the world. It provides major benefits in the preparation, analysis and communication of business information. It offers cost savings, greater efficiency and improved accuracy and reliability to all those involved in supplying or using financial data. XBRL is a kind of XML application based on the open Internet technologies. We propose a framework for enterprise information supply chain using XBRL Web services. A Web service is defined as a software system based on XML and designed to support interoperable machine-to-machine interaction over a network by the W3C. Web services are frequently just application programming interfaces (API) that can be accessed over a network, such as the internet and executed on a remote system hosting the requested services. An XBRL Web service-based enterprise information supply chain enables for companies to implement seamless information supply chains from businesses to financial institutions, to supervisory authorities, and to other stake holders for real time information access. And thereby it is expected to contribute to the increase in the value of companies due to the enhanced visibility and transparency of accounting and management.

  • Pavement Management System has a special purpose that the rehabilitation strategy applied on pavement should be executable in view of technical and economical point after new pavement open to the traffic. To achieve that purpose, a reliable pavement performance prediction model should be embeded in the system. The object of this study is to develop a probabilistic pavement performance prediction model for evaluating asphalt pavements based on the Markov chain concept. In this paper, methodology of the Markov chain modeling principle is explained, and the application of this model to asphalt pavement is described. As the results, transition matrics for predicting asphalt pavement performance are obtained, and also performance life is estimated quantitatively by this system.

  • With the rapid development of IT technology, integration with existing industries has led to an increase in smart manufacturing that simplifies processes and increases productivity based on 4th industrial revolution technology. Security threats are also increasing and there are. In the case of supply chain attacks, it is difficult to detect them in advance and the scale of the damage is extremely large, so they have emerged as next-generation security threats, and research into detection technology is necessary. Therefore, in this paper, we collect, store, analyze, and visualize logs in multiple environments in real time using ELK Stack and Sysmon, which are open source-based analysis solutions, to derive information such as abnormal behavior related to supply chain attacks, and efficiently We try to provide an effective detection method.

  • The mobile-phone which Camera was put on was released at the end of 2000 and dramatically puts up the deployment ratio because not only simple Camera but also a function that the photograph which I took is dispatched was added. It is the force that demand in this year presses 600,000,000 sale of a mobile-phone is estimated to be 960,000,000 of them in 2006, and to be able to include two errands with a support model after 3G. A person of entry to a camera-module appear much. In addition, the various kinds of products open markedly which a product comes to be known widely in the world, and the application range has opened widely, and considered QCDT come to be key issues for answer to market demand. By manufacturing industry, there is peculiar culture to each industry, camera-module is the composition the various industries. The construction of true Supply-chain becomes unavoidable to make a good product. I describe the point that the situation of each supply-chain and the direction for the future by the view point of module assembly maker.

  • This paper considers a web-based order processing system under SCM environment. Following the framework of B2B electronic commerce, we focus on activities closely related to order handling within the supply chain. We also try to integrate the order processing system with the overall information system of the company. The methodology is applied to the case of H company and a prototype system is designed. This study analyzes the current product estimate and order handling process in the point of view of both the purchasing and the selling companies. It intends improvement by changing the existing closed way of request and offering estimate through fax or VAN into an open way using internet. For this, a company should be registered on the order site of internet. Then it can request estimate, take estimate, and handle order through internet adopting the concept of electrical commercial transaction.

  • East Asian region, specifically China, Japan, and Korea, is considered as an area of advanced mobile handsets and mobile services. The well-established infrastructure of this region is well known due to rapid introduction of diverse feature-equipped handsets and advanced capabilities of mobile network operators. However, the status of mobile business has rarely been dealt with in previous studies. In this paper, we compare mobile value chains among these three countries. China has adopted open platform for mobile data services while Korea and Japan's mobile network operators control mobile portals for accessing diverse contents and services. We also discuss some possible reasons for the differences among the three countries in terms of value chain structures.
