본 연구는 경기지역의 상호대차데이터를 분석하여 상호대차 장서의 지역 간 네트워크를 분석하여 보고자 하였다. 경기지역 공공도서관의 지역 간 상호대차 장서의 네트워크를 분석하여 장서의 이동이 어떻게 이루어지는가 파악함으로써 실무기반 데이터의 활용 방안을 모색해보았다. 이를 통하여 효율적 상호대차를 위하여 지역을 권역별로 나누어 상호대차를 실시한다면 더욱 원할한 상호대차가 이루어질 수 있음을 확인하였다.

Through the development of efficient data collecting technologies like RFID, and inter-enterprise collaboration platforms such as web services, companies which participate in supply chains can acquire visibility over the whole supply chain, and can make decisions to optimize the overall supply chain networks and processes, based on the extracted knowledge from historical data collected by the visibility system. Although not currently active, the MeatWatch system has been developed, and is used in part for this purpose, in the imported beef distribution network in Korea. However, the imported beef distribution network is too complicated to analyze its various aspects using ordinary process analysis approaches. In this paper, we suggest a novel approach, called RFID-based supply chain process mining, to automatically discover and analyze the overall supply chain processes from the distributed RFID event data, without any prior knowledge. The proposed approach was implemented and validated, by using a case study of the imported beef distribution network in Korea. Specifically we demonstrated that the proposed approach can be successfully applied to discover supply chain networks from the distributed event data, to simplify the supply chain networks, and to analyze anomaly of the distribution networks. Such novel process mining functionalities can reinforce the capability of traceability services like MeatWatch in the future.

The research objective was to analyze the effect of work behavior on organizational citizenship behavior (OCB) and organizational commitment. For this, we analyze the effect of organizational commitment on OCB and analyze organizational commitment as a mediating variable in the relationship between workplace behavior and OCB. This study employed survey data for 80 employees of 12 village credit institutions in the Badung Regency. Observation is one way to obtain primary data. It is done by observing the object, which is the primary source of data, and conducting direct observations of the research location to determine the circumstances and problems. This research uses data collection techniques: 1) interviews conducted with employees working in Badung Regency both in managers and staff positions. 2) Questionnaire, namely, by using several closed questions given to the Badung Regency employees regarding workplace spirituality, organizational commitment, and OCB. The analysis technique used the partial least squares (PLS) approach and the Sobel test. The results show that workplace spirituality does not affect OCB but positively affects organizational commitment. Also, organizational commitment has a positive effect on OCB. The major findings are organizational commitment acts as a mediating variable in the relationship between workplace spirituality and OCB.

조선왕조실록은 UNESCO에 등재된 중요한 기록물이다. 본 논문은 한글로 번역된 조선왕조 실록에서 단어의 빈도수를 조사하여 빅데이터를 분석하는 방법을 제안한다. 조선왕조 실록을 인터넷 사이트에서 액세스하여 단어의 빈도수를 조사하려 할 때, 그 페이지에 포함된 소스를 직접 액세스하면 HTML 문법에 필요한 키워드가 포함되어 있어 필요한 본문에서 단어 빈도수에 의한 빅데이터 분석을 하는 것이 어렵다. 본 논문에서는 Java의 Jsoup를 활용한 크롤링 기능을 사용하여 조선왕조 실록의 본문을 분석하는 방법을 제안한다. 실험에서는 조선왕조실록의 태조부분만을 추출하여 본 방법의 유효성을 검증하였다.

In this paper, we analyze the traffic characteristics in microcell and macrocell overlaid PCS system which process voice and dta calls separately each others. in this system, data calls are delayed in queue when all of channels are occupied, while voice calls are bolcked in that case. For this, we calculated inter-microcell handoff area dwelling time distribution and handoff area dwelling time distribution between microcell and macrocell. We analyze traffic performance using this results. We used M/M/C/K model, and analyzed traffic performance of macrocell with handoff area variation of microcell.

Transmission control protocol(TCP) is protocol used in internet. TCP is seldom transmission error and is protocol based on wire environment. TCP uses 3 way handshake ways, data transmission control through windows size, data transmission control through reception confirmation, sliding window for packet delivery. In this study, designed TCP packet ion module for analyze the TCP segments & correct information about TCP. TCP capture in internet using designed TCP module and analysed TCP segments composition. Through this, could analyze the correct information of protocol in network.

Several statistical methods are introduced 1=o analyze the accelerated failure time data. Most frequently used method is the log-linear approach with parametric assumption. Since the accelerated failure time experiments are exposed to many environmental restrictions, parametric log-linear relationship might not be working properly to analyze the resulting data. The models proposed by Buckley and James(1979) and Stute(1993) could be useful in the situation where parametric log-linear method could not be applicable. Those methods are introduced in accelerated experimental situation under the thermal acceleration and discussed through an illustrated example.

In this paper, we attempt to analyze consumer preference for the alternative-fuel vehicles based on data from a stated preference using the conjoint analysis. Five possible fuel types (gasoline, diesel, CNG, LPG, Hybrid (electricity+gasoline)) are covered in conjoint cards. To estimate and analyze consumer preference, discrete choice model is used. Specifically, Bayesian mixed logit model is used. Based on estimating results, we discuss the business strategy and policy for the alternative fuel vehicle.
