  • 본 연구에서는 인간의 촉감 메커니즘을 반영하여 햅틱 인지 요인을 적용할 수 있는 진동 촉감 인터페이스 설계 프로세스를 제안하였다. 본 프로세스는 총 4단계로 햅틱 감각의 요구사항 분석 단계, 햅틱 요소 분석 단계, 햅틱 인지 요인분석 단계, 햅틱 요구사항 상세 설계 및 시제품 구현 단계로 구성된다. 본 설계 프로세스의 장점은 햅틱 인지 요인 분석을 적용함으로써 사용자 요구사항 도출 및 구현 시 불필요한 작업들을 배제할 수 있으며, 가장 큰 특징은 인체공학적 특징을 설계에 반영할 수 있고, 사용자 평가와 사용성 테스트, 햅틱 기능 최적화 작업을 동시에 수행함으로써 시제품 개발이 완료됨과 동시에 햅틱 요구사항 명세서가 완료된다는 것이다. 본 설계 프로세스는 사용자의 요구사항에서부터 햅틱 기능 상세설계 및 시제품 구현에 대한 전체 단계를 포함하고 있어 햅틱에 대한 전문 지식이 부족한 일반 개발자들도 사용자 중심의 설계가 가능하여 일정 수준 이상의 햅틱 기능 설계 및 구현을 가능케 할 것으로 기대된다.

  • Purpose - Goal setting is effective in any domain in which an individual or group has some control over the outcomes. It applies not only to work tasks but also to sports and health, and in various other settings. Its success depends on considering the mediators and moderators determining its efficacy and applicability. This study investigates the individual factors influencing academic goal attainability. Unlike previous studies, we focused on the effect of the relationships between individual traits (passion, tenacity, self-control) and specific motivation (vision, self-efficacy, implementation intentions) with academic goal attainability, rather than the effects of the relationship between commitment and the goal shielding mechanism with goal attainability. Research design, data, and methodology - Data collected through questionnaires were analyzed by the SPSS program. A total of 293 school students, who participated in the TOEIC program, participated in the survey. Slightly more than half were female (male: n=145 vs. female: n=148). We verified nine hypotheses through various statistical methods (reliability analysis, exploratory factor analysis, confirmatory factor analysis, structural equation model for the hypothesis test, bootstrapping test for the mediation test). Results - Data was analyzed in three phases. The first phase involved measurement analysis (i.e., item purification and factor structure confirmation), involving the scales of the three variables of individual traits, three mechanism variables, and goal attainability. The second phase involved estimating the proposed structural relationships among the key constructs (see Figure 1), using the results to test H1 to H9. The final phase involved examining the mediating effects of the three variables (vision, implementation intention, and self-efficacy). The research model shows that the independent variable passion has a significant result with both the mediators-vision and self-efficacy. Further, vision and self-efficacy significantly affect goal attainability. The second variable, self-control, shows a significant effect when mediated by implementation intentions, but the direct relationship between implementation intension and goal attainability shows an insignificant result. However, when further mediated by self-efficacy, it showed a significant effect between self-efficacy and goal attainability. Similarly, the third variable, tenacity, shows an insignificant result when mediated by vision. In contrast, the mediator self-efficacy shows a positive effect between tenacity and goal attainability. Conclusions - This study shows how these individual traits, when mediated with the appropriate motivational factors, resulted significantly in the attainability of academic goals. We may identify several theoretical and practical contributions. Theoretically, we developed a step further in the research into consumer goals and related studies. Future research could examine the effects of different learning goal types and their combinations with performance goals (e.g., learning goals first, then performance goals), different types of goal framing (approach success vs. avoid failure), the relation between goals and cognition (which, by implication, entails all of cognitive psychology), goal hierarchies, and macro goal studies with organizations of different sizes. More studies on the relationship between conscious and subconscious goals would also be valuable.

  • 수학교과에서 문제중심학습(PBL)은 학습자가 수학적 지식을 활용하여 문제를 해결해 나가는 과정 중에 수학적 개념과 원리를 알게 되고 수학적 사고 능력을 시켜줄 수 있는 교수 학습 방법으로 최근 관심이 높아지고 있다. 그러나 이러한 관심에 비해 실제 적용은 미미한 실정이다. 따라서 본 연구에서는 PBL의 학교 현장 적용을 위하여 수학교사들이 실제적으로 느끼는 어려움과 요구를 구체적으로 파악하고자 2명의 수학 교사를 대상으로 하여 카드활용 심층면담을 이용한 분류체계 분석과 성분 분석을 실시하였다. 그 결과 성공적인 PBL 적용을 위해서는 수학과 PBL 문제 개발에 대한 구체적인 방법의 안내와 수학교과에 적합한 PBL 학습 과정 안내 등의 구체적인 실행 방법에 대한 요구가 있음을 알 수 있었다.

  • This paper presents the results of the systems analysis for the FCIM (Flexible Computer Integrated Manufacturing) system at the U.S. Tobyhanna Army Repair Depot, which is one of the RAMP (Rapid Acquisition of Manufactured Part) program sites for CALS implementation in the U.S. military. The FCIM system's acquisition and supply processes are represented by IDEFO function models and FCIM information systems are briefly decribed in this paper. The models presented here can be used at a reference for the development of CALS acquisition and supply systems. In addition. the distinction between input and control information on the IDEFO model it suggested from the practical modeling viewpoint.
