Enterprise Resource Planning(ERP) systems offer pervasive business functionality the applications encompass virtually all aspects of the business. Understanding and managing this pervasiveness will result in a successful and productive business application platform. Because of this pervasiveness, implementations have ranged from great successes to complete failures. This article has two distinctive parts. The first proposes and discusses a systematic process based on consulting experiences of LG CNS (leading information system company in Korea) for ERP selection. Also, the second provides the key factors that are critical to the successful implementation of ERP. The second part reports the results of a study carried out to assess a number of different ERP implementations in different organizations. A case study method of investigation was used, and the experiences of five Korean manufacturing companies were documented. The critical factors in the adoption of ERP are identified as: learning from the experiences of others, appointment of a process innovator, establishment of committees and project teams, training and technical support for the users, and appropriate changes to the organizational structure and managerial responsibilities.

We investigate a chain of properties of real function algebras along the analogous proofs of the complex cases such as the fact that any real function algebra which is both maximal and essential is pervasive. And some properties of real function algebras with a vertex property will be discussed.

Multiple objective programming has been a popular research area since 1970. The pervasiveness of multiple objective in decision problems have led to explosive growth during the 1980's. Several approaches (interactive methods, feasible direction methods, criterion weight space methods, Lagrange multiplies methods, etc) have been developed for solving decision problems having multiple objectives. However there are still many mathematically challengings including multiple objective integer, nonlinear optimization problems which require further mathematically oriented research. (omitted)

Despite various types of online social networks having different topological and functional characteristics, the kinds of online social networks considered in social recommendations are highly restricted. The pervasiveness of social networks has brought scholarly attention to expanding the scope of social recommendations into more diverse and less explored types of online social networks. As a preliminary attempt, this study examined the information-sharing patterns of a new type of online social network - unilateral (directed) network - and assessed the feasibility of the network as a useful information source. Specifically, this study mainly focused on the presence of shared interests in unilateral networks, because the shared information is the inevitable condition for utilizing the networks as a feasible source of personalized recommendations. As the results, we discovered that user pairs with direct and distant links shared significantly more similar information than the other non-connected pairs. Individual users' social properties were also significantly correlated with the degree of their information similarity with social connections. We also found the substitutability of online social networks for the top cohorts anonymously chosen by the collaborative filtering algorithm.

In this study the information requirements of the personnel of Korean general hospitals are investigated. The results of the survey reveal that the information requirements of the general hospital personnel are quite different from each other according to their occupation type. The results show that the integrity of information about patients and the pervasiveness of information regarding to overall hospital operations are two major factors that differentiates the information requirements variation among occupation types of general hospital personnel. The results show that doctors, nurses, and medical technologists can be grouped into a occupation group, and that the admission department personnel and the patient affairs personnel can be grouped into another group. The results also show pharmacists and nutrition technicians constitute separate occupation groups of their own, respectively.

Despite the increasing pervasiveness of electronic commerce, very little empirical research has been done to examine its use in organizational contexts. Based on theories from the technological innovation literature, we developed an integrated model of electronic commerce initiation, adoption and implementation in Korea. We selected a random sample of 500 Korean leading companies. A questionnaire survey examined factors in initiation, adoption, and implementation of electronic commerce. Independent variables of this research were environment uncertainty, organizational characteristics(namely, organizational size, centralization, and formalization), and information system maturity. The resultant study sample included 62 firms across the industries. The empirical tests of the hypotheses were performed. According to our findings, environmental uncertainty, centralization, formalization, and information system maturity have a significant effect on the electronic commerce initiation, adoption and implementation.

Perceived game realism (PGR) has recently emerged as a key concept in explaining the mental processing of digital game playing and the societal impact of digital games. However, few studies have examined its conceptualization and educational effects from an empirical viewpoint, especially in educational games. This study's participants included 292 university students in South Korea. A total of 212 questionnaires were valid and used for the analyses. They learned English expressions using a computer-based educational game and then completed questionnaires on the research variables. We investigated six factors of PGR: simulational realism (SIR), freedom of choice (FRC), perceptual pervasiveness (PEP), social realism (SOR), authenticity (AUT), and character involvement (CAI). We expected the factors to have valid effects on the university students' flow and learning satisfaction after a game-based learning (GBL) experience. Our research results demonstrated a causal relationship between SIR, FRC, CAI, and learning satisfaction. Furthermore, the indirect effects of SIR and CAI on learning satisfaction through flow were statistically significant.

경찰 조직 내에서 갈등 관리는 조직 관리 관점에서 중요한 영역 중 하나이다. 본 연구는 경찰 조직 내에서 절차적인 어려움에 직면할 때 경찰 관리자들이 절차적 혁신성을 갖는지 탐색하고자 한다. 이 연구는 사례 연구 전략을 채택하여 일본, 미국 및 한국의 3개 경찰기관에서 있었던 실제 사례를 조사하였다. 각 경찰기관의 경찰관들을 인터뷰하여, (1) 위계적 권위의 만연, (2) 절차상의 갈등, (3) 조직 문화, (4) 가치와 가정의 기원, (5) 전략의 특성, 그리고 (6) 조직 학습이라는 6가지 주제를 이끌어냈다. 연구 결과에 따르면, 각 경찰기관의 절차적 갈등에 대한 대처 전략에서 유사점이 차이점보다 많았으며, 계층적 권한의 만연, 비공식 네트워크의 중요성 및 비공식 네트워크의 특성이 그 예이다. 핵심적인 결론은 경찰 관리자들이 절차상의 갈등을 극복하기 위해 비공식 네트워크에 상당히 의존했다는 것이다. 연구 참가자들은 비공식적 의사소통에 의존하여 조직의 적응력과 생존 가능성을 높이고자 하였다. 또한, 사회 문화적인 요인이 경찰 조직에 영향을 주었고, 이는 비공식 네트워크의 역할을 지지하는 결과를 가져왔다. 이러한 연구 결과는 공식적인 조직 내에 비공식적인 요소가 크게 자리잡고 있다는 역설을 보여주는 것으로 경찰 조직의 현실을 반영한 것으로 보인다.

본 논문은 학습된 낙관주의 관점에서 '메이플스토리' NPC들의 대화 내용을 분석하였다. NPC의 대화는 게임 이용자들의 재미와 성취욕구 부여에 큰 역할을 하며, NPC와의 반복적이고 장기적인 대화는 유저의 사고에도 영향을 미칠 수 있다. 본 연구에서는 학습된 낙관주의 설명 양식의 핵심적인 2가지 차원인 영속성과 파급성의 요소를 활용하여 분석한 결과, NPC들의 낙관주의적 언어 사용 비율은 대략 6~7%로 확인되었다. 낙관적인 대화성향을 지닌 NPC와 지속적인 소통은 게임 해비유저에게 유사한 사고를 학습할 기회를 부여할 수 있어 향후 NPC인공지능 개발시 중요한 고려사항임을 확인하였다.

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.
