Objectives of this study are to analyze the previous research perfomed in the Bus Information System (BIS) area and to suggest future research directions. This is a very meaningful and important work. To accomplish this, this study (1) summarizes the concepts of BIS, (2) establishes a research framework to be used to analyze the previous studies in the area, and (3) identifies and suggest trends and future directions of the BIS research. This study has identified total of 68 article (22 foreign and 46 domestic) using 'Google Scholoar' search engine. Major research results include (1) since non-empirical research is dominant, more explanatory empirical research is needed in the future, (2) research that provides consistent and comprehensive measures for BIS related constructs (e.g., BIS quality) is needed, and (3) impacts on the stakeholders of BIS not reflected in the current research (e.g., bus drivers, administrative agencies) should be analyzed in the future research.

Nowadays, technologies are changing through industrial fusion and government & corporates need to predict the flow & direction of technologies. These flow & direction can be grasped through the analysis of patent information. The patent information uses the common classification codes in the world, and it is possible for the quantitative analysis based on objective data with the time information of technical area. The methods of patent analysis analyzed the technology fusion by using citation analysis & simultaneous classification analysis. This research analyzed patent information which used as an index to measure the technical innovation in the society based on knowledge, and would like to analyze technical trends and to describe the way of improvement in the future based on the aviation industry which is the representative fusion/complex industry.

본 실험은 청각 사상관련전위(ERP)를 이용하여 다양한 성격 특질 모형들의 생물학적 근거와, 구조의 공통점과 차이점을 명확히 하기 위해서 설계되었다. 48명의 대학생 피험자들에게 4가지 성격 측정 검사(NEO-PI-R, EPQ-R, BIS/BAS 척도, IVE)를 시행하고, 이어 두 종류의 청각 자극 세트(50ms와 300ms)를 이용한 오드볼 과제를 통해 ERP를 측정하였다. 설문지 간의 상관과, 설문지와 ERP 내외생적 구성 요소 간의 상관, 그리고 그 상관의 두피 분포 양상을 통합적으로 고려하여 해석하였다. 각 성격 검사의 외향성 척도에 해당한다 할 수 있는 E, E, BAS-FUN은 양성 모두에서 높은 수준의 설문지 척도 간 정적 상관을 보였으나, 50ms 자극으로 유발된 P3 진폭은 E와 BAS-FUN에 대해서만 유의하게 높은 상관을 나타내었다. 이 결과는 Eysenck의 모델과 일견 일치하는 결과이지만, 그가 개발한 EPQ-R의 외향성 척도(E) 보다는 오히려 다른 척도들이 뇌파에 반영된 성격의 생물학적 기제를 측정하기 위한 적절한 도구일 수도 있음을 시사한다. 신경증적 경향성을 반영하는 N과 N 척도는 50ms 자극에 대한 여성 피험자의 N1, P2 진폭과 유의한 상관을 보였다. 그러나 이론적으로 두 척도에 등가적인 것으로 예상되었던 BIS 척도는 설문지 간 상관이나 ERP 요소와의 상관에서 모두 유의한 결과를 보이지 않았다. Eysenck가 성격의 세 번째 축(차원)으로 제시했던 P(정신병적 경향성) 역시 여성 피험자들에게서 두드러지는 설문지 간 상관을 보였으나, 300ms 자극에 대한 P2 진폭과의 정적인 상관은 양성을 합한 자료에서만 발견되었다. 여성의 상관 분포는 비록 통계적으로 유의한 수준에는 이르지 못하였으나, 양성 자료의 분포와 유사함이 확인되었다. 이 실험의 결과는 P3 진폭과 외향성 간의 부적인 상관 관계를 보고하였던 기존 연구들을 지지한다. 또한 본 실험에서 확인된 Eysenck 모델의 신경증적 경향성이나 정신병적 경향성이 ERP의 비교적 초기에 나타나는 외생적 구성 요소들(N1, P2)과의 상관 양상은, P3 요소에 집중하였던 기존 연구들이 외향성 이외의 차원으로 일관된 결과를 얻어내지 못했던 이유를 설명해줄 수 있을 것이다. 또한 성격 차원과 그것을 지표 하는 ERP 구성 요소 간의 관계를 해석할 때에 성별이나 유발 자극의 속성을 고려해야 함을 보여준다.

This paper focuses on the systematic conceptualization of the 'contents' through the differentiation between the meanings of the work of art and the contents. The 'contents' are referred to as various media products, but they are all the audience-oriented work of art. From the beginning of its birth the film medium turned out to be a kind of contents, which is involved in the specific role of audience. It also implies that the film medium could not exist without the interaction of the media text and audience. In order to understand this context, this paper analyzes the film of Alfred Hitchcock.

To characterize virtual reflection images of deep subsurface by the method of seismic interferometry, we analyzed effects of offset range, ambient noise, missing data, and statics on interferograms. For the analyses, seismic energy was simulated to be generated by a 5 Hz point source at the surface. Vertical components of particle velocity were computed at 201 sensor locations at 100 m depths of 1 km intervals by the finite difference method. Each pair of synthetic seismic traces was cross-correlated to generate stacked reflection section by the conventional processing method. Wide-angle reflection problems in reflection interferometry can be minimized by setting a maximum offset range. Ambient noise, missing data, and statics turn to yield processing noise that spreads out from virtual sources due to stretch mutes during normal moveout corrections. The level of processing noise is most sensitive to amplitude and duration time of ambient noise in stacked sections but also affected by number of missing data and the amount of statics.

It is time to review the direction of R&D investment which is the source of change in knowledge information ages. The DEA(Data Envelopment Analysis) is a efficient method by using the ratio of input and output elements. In this paper, we analyzed industry relationship and efficiency by DEA in order to analyze ripple effect of the regional industry technology development project. According to these results, we found the primary affected factor in performance of this project was human resource, and the turnover of participated company was not on the rise yet. On types of the project, we could find the efficiency quotient of critical technique development project was higher than of common technique development project because project period or budget scale infected to project performance. We expect the enhancement of technique developer, tenn and budget, and it is necessary the project results should lead performance such as sales force and employee growth.

This paper describes the design and implementation of a grid system META (Metacomputing Environment using Test-run of Application) which facilitates the execution of a CFD (Computational Fluid Dynamics) analysis program on distributed environment. The grid system META allows the CFD program developers can access the computing resources distributed over the network just like one computer system. The research issues involved in the grid computing include fault-tolerance, computing resource selection, and user-interface design. In this paper, we exploits an automatic resource selection scheme for executing the parallel SPMD (Single Program Multiple Data) application written in MPI (Message Passing Interface). The proposed resource selection scheme is informed from the network latency time and the elapsed time of the kernel loop attained from test-run. The network latency time highly influences the executional performance when a parallel program is distributed and executed over several systems. The elapsed time of the kernel loop can be used as an estimator of the whole execution time of the CFD Program due to a common characteristic of CFD programs. The kernel loop consumes over 90% of the whole execution time of a CFD program.

In the digital information environment records have an even closer relationship with business processes and become a core element of organizations' managerial activities. In practice, management is represented as congregation of business outcomes. The importance of records management is increasingly emphasized in terms of organizations' compliance, knowledge-management and risk management. However, there is currently no academic discussion on a between records management and managerial activities. In this context, the study has the notion that this should be defined and acknowledged for public institutions' effective records management. Based on the Malcolm Baldrige Model and ISO 15489, the study discusses a close between records management and management quality. The records management elements of the Malcolm Baldrige model and the managerial quality elements of ISO 15489 were analyzed. Based on the analysis, both common and neglected elements were explored in terms of records management.

In this paper, we proposes a comprehensive analysis of the characteristics, selection procedures, and management perspectives of each university's financial support project, and derivation of a plan to integrate the information system of the university's financial support project. To this end, we analyze the current status of business operations before and after restructuring university financial support projects, and identified the characteristics, commonalities, and differences of each project. Individual projects are promoted segmentally, evaluation indicators and evaluation methods are different for each business, standardization is difficult, and in the absence of integrated governance, sympathy and will of the system integration of the government and the managing agency cannot be found. In order to integrate the system, the business management process must be integrated and standardized, and the system equipment such as budget category adjustment must be complemented, and a stable budget for system integration must be secured.
