급변하는 외부 환경에서 생존하기 위해 대부분의 기업은 비즈니스 프로세스를 혁신하거나 개선하고자 노력하고 있으며, 이를 위해 많은 기업들이 프로세스 운영에 BPM (Business Process Management) 개념을 도입하고 있다. 기업에서 BPM 단계는 진단-설계-구현-실행 순으로 진행되는데, BPM 생애 주기에서 통상적으로 비즈니스 프로세스의 진단은 지금까지 주로 인터뷰나 설문지 또는 프로세스를 직접 관찰하는 방식과 같이 수작업으로 이루어졌다. 비즈니스 프로세스의 (재)설계 방법도 주로 백지 상태에서 시작하여 전문가의 지식에 의존하는 수작업 방식으로 이루어져 왔다. 이 연구의 목적은 프로세스 진단 단계에서 프로세스 마이닝을 이용하여 자동으로 생성된 프로세스 모델과 통계량을 (재)설계 단계에서도 공유함으로써 별개로 행해지던 진단과 설계 업무를 통합하려는 것이다. 이러한 시도의 궁극적인 목표는 비즈니스 프로세스 진단과 설계 업무를 자동화하려는 것이다. 제안 프레임워크를 구현하고 유용성을 제시하기 위해 두 개의 사례 연구를 행하였다.

This paper examines the interactions between financial conditions and business cycles in Mongolia, a small open economy, heavily depending on commodity exports. We construct two financial conditions indexes based on the reduced form IS model and the vector autoregression (VAR) model as surveillance tools to quantify the degree of the financial conditions. We find that real short-term interest rate and real effective exchange rate gap get a higher weight in the FCIs. Both business and financial cycles are often more pronounced in Mongolia, and financial condition is dependent of the financial and monetary policies in place. The analysis of the predictive power of the FCIs for business cycles shows that they have predictive information for the near-term economic activities. FCIs are also helpful in signaling inflation turning points.

Purpose - Many studies report that returns on hedge portfolios that eliminate particular risk types are abnormal from traditional asset pricing models' perspectives. This study examines the pervasiveness of anomalous returns conditioned on business cycle and group size. Research design, data, and methodology - Using KOSPI and KOSDAQ market data from July 1991 to December 2013, we categorize stocks into appropriately sized groups, and dichotomize our sample periods into expansion and recession periods then, we construct hedge portfolios by sorting stocks by anomaly variables and calculate their returns. Results - Four anomalies, including earnings yield, net stock issue, total asset growth, and liquidity appear pervasive across all groups for the entire sample period. However, only the hedge returns of net stock issues are significant across all group sizes during both expansion and recession. Conclusions - A net stock issue can be an appropriate proxy for expected growth of book equity for all group sizes in recessions. This finding could provide insights to investment industry participants and to researchers interested in the relationship between expected growth of book equity and business cycle risk.

There has been a recent increase in the interest towards founding companies and in line with the South Korean Government's policy on start-up support, discussions are rife about the effect of entrepreneurship on the management and performances of these companies. To enhance the competitiveness of SMEs, it is expedient to acquire and deploy consistent entrepreneurship, differentiate corporate resources, ensure the appropriate utilization of resources and the integration of such factors in response to the changing environment. This research examines relationships among entrepreneurship, three components of corporate capabilities, dynamic capability and technical performance based on resource-based view and the dynamic capability theory. The authors also investigate the moderating role of corporate life cycle. To test the hypothesis, we conducted a survey on 352 technologies -innovative SMEs located in South Korea via professional research institutes. The findings confirm the hypothesis that SMEs' entrepreneurship has a positive effect on three kinds of corporate capabilities (e.g., marketing, R&D, operations capability), and it had a positive effect on dynamic capability, whiles dynamic capability also had an influence on technical performances. The findings also confirmed the hypothesis that corporate life cycle moderates the relationship between dynamic capability and technical performances respectively. The research implications for both practitioners and academicians are discussed.

Using the frequency-based decomposition, I decompose the consumption growth to explain well-known patterns of stock returns in the Korean market. To be more specific, the consumption growth is decomposed by its half-life of shocks. The component over four years of half-life is called the business-cycle consumption component, and the components with half-lives under four years are short-run components. I compute the long-run and short-run components of stock excess returns as well and use component-by-component sensitivities to price stock portfolios. As a result, the business-cycle consumption risk with half-life of over four years is useful in explaining the cross-section of size-book-to-market portfolios and size-momentum portfolios in the Korean stock market. The short-run components have their own pricing abilities with mixed direction, so that the restricted one short-term factor model is rejected. The explanatory power with short- and long-run components is comparable to that of the Fama-French three-factor model. The components with one- to four-year half-lives are also helpful in explaining the returns. The results about the long-run components emphasize the importance of long-run component in consumption growth to explain the asset returns.

According to recent empirical studies, there is a systematic pattern in temporal behaviors of asset returns, and that systematic pattern is related to the business cycle. I propose a model which captures this evidence. This is done by considering a state dependent preference structure where state dependency is related to the business cycle. In this setting, the three main puzzles(i.e., the volatility puzzle, the equity premium puzzle, mean reversion) are understood as interrelated behaviors.

This paper presents an idea and framework to automate a full cycle business process management and re-engineering by integrating traditional business process management systems, process mining, data mining, machine learning, and simulation. We build our framework on the cloud-based platform such that various data sources can be incorporated. We design our systems to be extensible so that not only beneficial for practitioners of BPM, but also for researchers. Our framework can be used as a test bed for researchers without the complication of system integration. The automation of redesigning phase and selecting a baseline process model for deployment are the two main contributions of this study. In the redesigning phase, we deal with both the analysis of the existing process model and what-if analysis on how to improve the process at the same time, Additionally, improving a business process can be applied in a case by case basis that needs a lot of trial and error and huge data. In selecting the baseline process model, we need to compare many probable routes of business execution and calculate the most efficient one in respect to production cost and execution time. We also discuss the challenges and limitation of the framework, including the systems adoptability, technical difficulties and human factors.

This study aims to analyze the relationship between the business cycles of the ASEAN +3 countries. In addition, the effects of the spillover value on the coincident indicators are determined. This study employs secondary data and uses multivariate time series of five ASEAN countries, namely, Indonesia, Malaysia, Singapore, Thailand, and the Philippines. The proxy was the real gross domestic product (GDP) collected annually from the CEIC, the IMF, and the World Bank for the period from 1964 to 2016. The data was plotted against two time periods, 1964-1998 as the pre-crisis period, and 1999-2016 as the post-crisis period. The index data was changed to the base year 2010. The data was subsequently separated from the trends and the cyclic components. The cyclic components were obtained by using Hondrick-Prescott filter, and them were further analyzed. The analytical method used was Contemporaneous and Cross-Correlation tools. The results showed that, before and after the crisis, the value of the business cycle correlation between ASEAN +3 countries was stronger and moved together at the same level of lag value. The implication of this research was an initial finding of the ASEAN +3 countries' prerequisites for the formation of a common currency.

본 논문은 개인정보의 법적 및 기술적 특성을 고려한 라이프 사이클 모델들을 각각 검토했다. 그리고, 이를 토대로 국내 IT 기업에 적합한 '개인정보의 동의 관리 기반 모델'을 제안했다. 본 논문에서 제시한 모델은 기존의 모델이 간과하고 있던 '동의'와 '관리' 요소를 모델에 적극 반영했다는 특징이 있다. 본 모델의 타당성은 2가지 방식으로 검증했다. 첫째, IT 기업의 개인정보 라이프 사이클 구성 요소를 파악 후 모델별로 적용하여 '동의 관리' 모델의 우수성을 검증했다. 둘째, 개인정보의 라이프 사이클 전체 프로세스에 '동의'와 '관리' 내용이 포함됨을 입증했다. 본 연구 결과를 활용하면 IT 기업이 개인정보 활용 현황을 분석하고 보호 체계를 마련하는데 기여할 수 있을 것으로 기대된다.
