Based on a sample of corporations which have used E-mail at least three years, we found (1) no difference in the usage of E-mail depending on task analyzability, and (2) the usage of E-mail in the high analyzability group correlated more strongerly than in the low analyzability group with performance. A future study would be researched on the usage between computer-based communication media with other variables such as social influence.

맡고 있는 일에 문제가 발생했을 때 문제의 원인을 아는 정도로 분석성을 측정하고, 회사의 전체 업무를 이해하는 정도로 포괄성을 측정하고, 본인의 일에 예외적인 상황이 발생하는 정도로 유연성을 측정한다. 기업의 고정효과 또는 임의효과와 연령, 근속, 직위 직급 등 전통적인 인적자본 변수들을 통제한 후 이 특성들은 통계적으로 유의하게 임금을 높인다. 맡고 있는 일에 문제가 발생할 때 문제의 원인을 거의 모르는 자보다 대부분 정확히 아는 자가 임금이 5.2% 높다. 맡고 있는 팀(부서)의 업무만을 어느 정도 이해하고 있는 자보다 회사의 전반적인 업무를 이해하고 있는 자가 임금이 2.52% 높다. 일상적이고 반복적인 일을 하는 자보다 하나하나가 새로운 일을 하는 자가 임금이 2.98% 높다.

This paper analyzes 96 Korean companies to illustrate the relationship between the knowledge management strategies and task characteristics. Knowledge management strategies can be categorized as being codification- and personalization-oriented. Task characteristics are analyzed from the perspective of content-oriented, process-oriented, number of exceptions, and analyzability. These results illustrate how companies should align the knowledge management strategies with task characteristics. It is found that codification strategy is more likely to be associated with high content-oriented and high analyzability task, and personalization strategy is with high process-oriented task. The survey result confirms that managers should adjust knowledge management strategies in view of the characteristics of the task.

The purpose of this study is to confirm whether the fit between the task and the information characteristics makes any effects on the user satisfaction. The task is defined as two sub-constructs representing the degree of exception and analyzability. The information characteristics is divided into the degree of aggregation, scope and timeliness of information. User satisfaction was used as a surrogate measure of the performance of information systems. The computer self-efficacy was used to control any confounding effects. Field research method using questionnaires was employed to empirically investigate the relationship among the variables. Findings of the study are summarized as follows: the fit between the task and the aggregation of information and between the task and the scope of information turned out to have significant effects on information system performance. The implication of such results is that under highly exceptional or less analyzable task environment, less-aggregated or broad information is more appropriate.

It is well known that the web design is composed of several factors which are interacting with each other. However, the current approach to web design had been focused on modifying specific factors without considering its impact on other factors. In this sense, we propose more holistic approach to the web design by using fuzzy cognitive map. For this purpose, we form an illustrative fuzzy cognitive map for the web design which is based on the literature, and analyzed and impact of change in a specific factor on other factors. Especially, to improve the output analyzability, we suggested an advanced version of fuzzy cognitive map called stratified fuzzy cognitive map. After simulating the fuzzy cognitive map for web design, we could conclude that our approach is robust and effective compared to the traditional web design approach.

This study aims at the observation of some analytical levels-especially those of syntactico-semantical- of the visual expressions in general. As far as the syntactical parts are concerned, there were two steps to be approached. One is to select the paradigms according to the Saussure-Hambidgean suggestions, the other to derive syntagmas from what is called the 'chaos-system', one of nonlinear dynamics. In result, paradigms could be acquired 5 sorts with its so many varieties, as visual templates(VT), supplemented by their reciprocals(R) and complements(CLE), and syntagmas five orbits from each constant c=0 to c=10. In additional, in connection with semantic parts, the study introduced a Gremasian model of discourses and narratives for the interpretation of signifiers. By this, we could cover the conjunctive relationships(+) and the disjunctive(-) of the whole structure of visual expression. Finally, we certified that the above could be fully approved in terms of recent worldly cognitive scientic psychological discoveries.

Using end-user attitude as intervening variable, this paper proposes a causal model of how environmental factors of EUC influence end-user computing (EUC) success, measured by the degree of IS use. This study identifies unique aspects of the EUC environment and generates key dimensions of end-user attitude appropriate for this context : perceived information quality, perceived design quality, and perceived usefulness. The research model includes six environmental factors - top management support, end-user education, task variability, task analyzability, end-user's computing ability, and end-user involvement. A field study was undertaken to test the hypothesized relationships among the research variables. The results generally support the assumption that end-user attitude intervene the impact of environmental factors on IS use. The implications of the findings are discussed.

This paper has two primary objectives: (1) to propose a comprehensive theoretical model that incorporates valuable insights from two complementary streams of research, and (2) to empirically test the model that explain the task-media fit and satisfaction of customer contact center users. The comprehensive model was tested using LISREL analysis on the sample of 232 users who have experience with the customer contact center. The model was supported in customer contact center context, accounting for 29% of the variance in the task-media fit, 53% of the variance in the perceived ease of use, 61% of the variance in the perceived usefulness, and 52% of the variance in the user satisfaction. The results showed that the task-media fit, the perceived ease of use, and the perceived usefulness play a significant role in influencing the user satisfaction of the customer contact center. In addition, task analyzability, media richness, media interactivity, and self-efficacy were found to influence the task-media fit. The paper concludes with discussions and implications for researchers and practitioners.

임베디드 시스템 소프트웨어의 보안성 분석을 위한 동적 프로그램 분석을 시도하기 위해서는 디버거 체계가 필요하다. 타겟 장비가 범용 운영체제와 비슷한 환경을 지원하는 경우에는 소프트웨어 기반의 디버거 혹은 DBI 프레임웍 등을 장비 내에 설치하여 분석할 수 있으나, 설치 가능성 제한이나 분석 환경의 투명성 문제 등의 어려움이 있을 수 있다. JTAG (IEEE 1149.1)디버거 장비를 이용하여 분석하는 경우에는 분석을 위해 타겟 장비 내의 소프트웨어적 환경을 변경하지 않아도 된다. 타겟 장비의 보안성 분석을 위한 프로그램 동적 분석 기법들을 용이하게 적용하기 위해서는 JTAG 디버거 장비를 제어하기 위한 API가 필요하다. 본 논문에서는 ARM 코어 기반 임베디드 시스템 분석을 위한 JTAG API를 소개한다. 구현된 API는 JTAG 디버거 하드웨어를 직접 제어하며 디버깅 환경 및 동작제어를 위한 함수 세트를 제공한다. API의 활용 용이성을 확인하기 위하여 커널 함수 퍼징과 라이브 메모리 포렌식 기법을 적용한 보안 분석 도구의 예제 구현을 제시한다.
