Limiting probability in the steady state of regenerative process is one of the most useful characteristics. The formula for this limiting probability in the steady state of the regenerative process is presented in this paper. Because this formula is for the general model, it can be applied to many special systems including 2-unit redundant system. An example for this formula is also presented.

본 연구는 미국 켄터키 주에 소재한 머레이 주립대(Murray State University)가 제공하고 있는 주제별 맞춤형 정보제공(Library on Blackboard) 시스템의 기능들을 중심으로 현존하는 대학도서관 서비스가 온라인상에서 어떠한 정보기술을 통해 변형되어 제공될 수 있는지를 살펴보았다. 정보기술의 발달로 인하여 미국 대학교육에서 온라인 강의와 원거리 교육의 비중이 점점 늘어나는 추세이다. LMS(Learning Management System)는 새로운 대학 환경변화의 중요한 도구이다. 대학도서관의 정보제공 기능도 대학교육 환경의 변화에 발맞추어 발전해 왔고, 이에 따라 이용자에게 효과적인 서비스를 제공하기 위한 LMS와 연계한 맞춤형 정보검색 시스템을 개발하기에 이르렀다. LMS와 연계한 도서관 서비스는 학생들의 연구형 과제해결을 위한 정보수집에 적합한 검색시스템과 유용한 정보들을 한곳에 모은 가상 분관의 기능을 제공하기에 더욱 사용되고 발전해야 한다. 이 시스템을 더욱 발전시키기 위해서는 Contents Management Systems의 사용과 과목별 접근방식으로 변환이 중요하다.

Indicators of environmental conditions describe the state of the environment and the quantity and quality of natural resources. This study deduced the evaluation items to assess each sub-indicator for agricultural water quality and conducted the surveying using the Delphi method based on agricultural water quality experts. Considering its importance, environmental, state, and management indicators showed that state indicator such as COD concentration for surface water and $NO_3-N$ concentration for groundwater was ranked as first and followed by amount of fertilizer. Its indicators were correlated with state and environmental indicators in surface water and groundwater. The best management indicators were calculated to assess the agricultural surface water and ground water quality. The indicator could be used in established policies for management and conservation of water resources.

This study examines the role of Leadership style and Organizational culture in predicting employee Performance. The aim of the research is: 1) to know the direct effect of Democratic Leadership on employee Performance, 2) to know the direct effect of Democratic Leadership on organizational culture, 3) to know the direct effect of Organizational culture on employee Performance, 4) to test the role of Organizational culture as mediation the effect of Democratic Leadership on employee Performance. The respondents were all employees at the Education Office East Java. The sampling method was used to collect data from 106 employees at the Education Office East Java, Indonesia, using surveys and questionnaires. The data obtained were analyzed using the Path Analysis with SPSS statistical software. The study had four findings. Firstly, Democratic Leadership has a significant effect on employee Performance. Secondly, Democratic Leadership also has a significant effect on Organizational culture. Thirdly, Organizational culture has a significant effect on employee performance. Fourthly, organizational culture mediates the effect of Democratic Leadership on employee Performance. Furthermore, the direct effect of Leadership style and the mediation role contribute to knowledge. The results showed that implementing Democratic Leadership supported by a conducive organizational culture guides employee to perform better.

This research aims to analyze the impact of Financial Risk (FR), Information Asymmetric (IA), and Earning Power (EP) on Real Earning Management (REM) of listed trading companies in IDX Indonesia. This study aims to analyze the influence of FR, IA, EP, on REM through Operating Cash Flow, Production expense, and Discretionary Expense. The study employs an unbalanced panel of data set from 2014 to 2018 on the activity of all trading companies (15 in total) as selected samples of 48 feasible samples from 144 existing data. The sample used a non probability sampling method with a purposive sampling technique. This research was classified as causative and tested by multiple linear regression model with cross-sectional analysis. The result indicated a significant impact of FR on REM through PROD and DISX but not through COF. How ever, IA, and EP showed significant impact on REM by means of COF but not go by PROD and DISX..The findings in this study contribute to the users of financial reports particularly the stakeholders in defining the determinants of real earning management practices among firms when it comes to decision making.

Principal challenges to $\underline{direct\;fabrication}$ of high performance a-Si:H transistor arrays on flexible substrates include automated handling through bonding-debonding processes, substrate-compatible low temperature fabrication processes, management of dimensional instability of plastic substrates, and planarization and management of CTE mismatch for stainless steel foils. Viable solutions to address these challenges are described.

In order to explain the U-shaped pattern of autocorrelations of stock returns i.e., autocorrelations starting around 0 for short-term horizons and becoming negative and then moving toward 0 for long-term horizons, researchers suggested the use of a state-space model consisting of an I(1) permanent component and an AR(1) stationary component, where the two components are assumed to be independent. They concluded that auto-regression coefficients derived from the state-space model follow a U-shape pattern and thus there is mean-reversion in stock prices. In this paper, we show that only negative autocorrelations are feasible under the assumption that the permanent component and the stationary component are independent in the state-space model. When the two components are allowed to be correlated in the state-space model, we show that the sign of the auto-regression coefficients is not restricted as negative. Monthly return data for all NYSE stocks for the period from 1926 to 2007 support the state-space model with correlated noise processes. However, the auto-regression coefficients of the ARIMA process, equivalent to the state-space model with correlated noise processes, do not follow a U-shaped pattern, but are always positive.
