  • In this paper we study consumption-labor supply decision of an agent who prepares for retirement at a known time in the future. The agent is assumed to have a preference which is represented by the von Neumann-Morgenstern utility function in which the felicity function has constant relative risk aversion over the composite of consumption and leisure. The composite is obtained by the Cobb-Douglas function. A general problem has been studied by Bodie et al. (2004). We contribute to the literature by deriving the Slutsky equations and conducting comparative statics. In particular, we show that wealth effect can exhibit an interesting property depending upon the time until retirement, as the interest rate increases.

  • With the widespread use of social media, online social platforms like Twitter have become a place of rapid dissemination of information-both accurate and inaccurate. After the COVID-19 outbreak, the overabundance of fake information and rumours on online social platforms about the COVID-19 pandemic has spread over society as quickly as the virus itself. As a result, fake news poses a significant threat to effective virus response by negatively affecting people's willingness to follow the proper public health guidelines and protocols, which makes it important to identify fake information from online platforms for the public interest. In this research, we introduce an approach to detect fake news using deep learning techniques, which outperform traditional machine learning techniques with a 93.1% accuracy. We then investigate the content differences between real and fake news by applying topic modeling and linguistic analysis. Our results show that topics on Politics and Government services are most common in fake news. In addition, we found that fake news has lower analytic and authenticity scores than real news. With the findings, we discuss important academic and practical implications of the study.

  • Purpose: To explore the application prospect of support vector machine (SVM) in supply chain management and its practical application in supply chain performance evaluation practice. Research design, data and methodology: This paper establishes the performance evaluation index system of supply chain management according to the balanced scorecard (BSC) theory, and establishes the SVM model of supply chain management performance evaluation based on the SVM principle. Results: The performance evaluation results of the supply chain of an electric power equipment Co., Ltd. in Harbin established by using the model are consistent with the actual situation, which indicates the nature and accuracy of the possible reflection of the established supply chain performance evaluation model. Conclusions: The results show that SVM model can be used to evaluate enterprise supply chain management performance indicators, and can improve enterprise supply chain management performance, thus demonstrating the effectiveness of the model.

  • The objective of this research is to analyze the effects of quality management system constructed by ISO 9001 certificates through BSC perspectives. Evaluation of quality management system based on BSC framework can consider short-term financial performance as well as nonfinancial performance characteristics, which will derive future financial results. This results show that QMS has an indirect effect on business performance through quality performance and customer satisfaction, which are internal business process and customer perspective, rather than have direct effects on financial performance. Finally we suggest implications of this study and future research direction.

  • Mobile business, noticed as a constructive alternative for e-commerce and e-business, has been diversely defined and conceptualized. This study develops a comprehensive framework for the sake of clearing such a havoc of conceptual deluge. The framework for the comprehensive understanding of e-business (including m-business) consists of two dimensions: connectivity and mobility. These two dimensions represent to overcome the constraints of time and place in business transactions, respectively. Various cases for each combination of these two components are explained for clear understanding of this framework. By this framework, we can understand the value that Location-Based Service (LBS) brings anew to e-business services.

The sample of this study consists on two countries listed bank sector Pakistan and China. The annul data is used from 2009-2018 to find the objective of this study. The Panel regression model is used to check the relationship between dependent and independent variables. Return on Asset and Return on Equity is used as performance checker dependent variables. The results of this study confirm board size coefficient value positive for ROA and negative for ROE but shows insignificant behavior for Pakistani banking sector while in Chinese banking sector the coefficient value of board size positively for ROA and ROE at 10% level. The board composition coefficient shows the negatively significant with ROA but insignificantly related to ROE for Pakistani banking sector. However, in Chinese banking sector the coefficient value of board composition is insignificant for both ROA and ROE. This study is helpful for banks, management of banks, policy makers, researcher as well as Government.

  • Nowadays many countries in the world have been implementing TQM which is originated from Japanese management style. There are many research results that TQM has a positive influences on business results. But the levels of implementing TQM are different by countries. The domestic competitors and the customers, who have the great influences on business results are also quite different. Therefore the levels of TQM in some company and the influences of TQM factors on business results are supposed to be different by countries. The situations of the countries lying on the more developed stage will be a good benchmarks for the countries on following stages. There are few researches on this cross countries analysis. This paper do the empirical study on the effects of TQM factors on business results between Korean and Japanese small or medium sized manufacturing companies. First, the levels of TQM are compared between countries. Second, what key success factors among TQM ones are for business success is analyzed for each country and compared between two countries. This study will help to plan the road maps in TQM journey for the Korean companies.

  • 시맨틱 웹(Semantic Web)의 비전에 대한 공표가 이루어진 이래로 이와 관련한 많은 연구가 진행되어 왔다. 그러나 지금까지의 연구가 성공적이었다는 판단을 하기에는 아직 이르다. 본 논문은 시맨틱 관련 연구분야의 두 가지 문제점을 진단한다. 첫째는 '시맨틱 검색'이라는 개념의 합의된 정의가 없다는 것이고, 둘째는 장래의 유관 연구를 바라볼 수 있는 종합적이고 체계적인 시각이 부족하다는 것이다. 이러한 진단 아래, 본 논문은 시맨틱 검색의 개념을 '사용자의 입력에 따라 온톨로지와 같은 시맨틱 기술을 이용하여 원하는 정보를 얻는 행위'로 정의한다. 또한 시맨틱 검색에 대한 이해를 돕기 위해 시맨틱 검색 엔진 분류 프레임워크를 제안하였다. 본 연구에서 제안하는 프레임워크는 (쿼리) 입력문의 처리, 타겟 소스, 검색 방법론, 검색결과의 서열화, 출력 결과물의 데이터 종류, 이렇게 다섯 가지 부분으로 나뉜다. 마지막으로 본 논문은 제시한 프레임워크를 응용하여 기존의 연구결과물을 분석하고 앞으로의 연구 방향을 논하는 것으로 끝을 맺는다.
