웹이 대중화 되면서 웹 사이트 개발의 초점이 개발자가 아닌 이를 사용하고 평가하게 될 사용자에게 맞춰지게 되고, 그에 따라 사용자가 쉽게 배우고 빨리 인식 할 수 있도록 개발하는 유저빌리티의 원리가 웹의 사용성을 향상시키는 데 있어서 중요한 역할을 하게 되었다. 본 연구는 웹 유저빌리티 요인인 컨텐츠, 디자인, 네비게이션, 상호작용성이 TAM의 지각된 유용성과 지각된 이용용이성을 매개로 고객 재방문 의도에 미치는 영향력을 검증함으로써 TAM을 확장하였다. 이 모형은 인터넷 서점을 방문한 경험이 있는 180명의 설문으로 LISREL분석이 사용되었다. 결과는 디자인을 제외한 컨텐츠, 네비게이션, 상호작용은 웹유저빌리티의 중요한 변수로써 지각된 이용용이성과 기각된 유용성을 매개로 재방문 의도에 영향을 맞는 것으로 밝혀졌다.

To construct the third generation model, nonlinear interaction was included in source terms. To calculate the nonlinear interaction, discrete interaction approximation to Boltzmann integral was used, as in WAM model. The general behavior and characteristics of nonlinear interaction were analyzed through the experiments for the durational growth and turning winds.

In this study, the fully coupled SWAT-MODFLOW model is developed by using the type of embedment MODFLOW in SWAT. Since SWAT model has semi distributed features, its groundwater component can't consider distributed parameters such as hydraulic conductivity, storage coefficient and spatially variable natures such as distribution of groundwater heads and pumping rate and so forth. The main purpose of this study is to overcome these limitations. This linkage is completed considering the interaction between stream network and aquifer to reflect boundary flow. To correspond HRU in SWAT to grid in MODFLOW, HRU-GRID conversion tool using DEM is newly suggested. As groundwater recharge of MODFLOW can be estimated accurately by SWAT model, the reliability of groundwater discharge and total runoff of watershed could be greatly enhanced.

In this study, a new dynamic interaction analysis method for tilting trains and curved track is presented. Three dimensional lumped parameter vehicle elements are used to model tilting train, and the proposed analysis technique can simulate driving direction change of vehicle, the effect of track cant, wheel-rail contact angle, and tilting angle of tilting trains, etc. The proposed method passed several basic verification tests, and it is expected that the suggested method is applicable for practical problems.

This study investigates how elementary students used cognitive-emotional rebuttals in the context of modeling activities, especially on how their emotional and cognitive processes lead them to use rebuttals in terms of epistemic affect. Twenty-five fifth grade elementary students participated in the study as part of their science class. During the course of their sixth periods, students constructed a human respiratory system model through continuous discussion. The research results showed that elementary students used an elaboration-oriented rebuttal, a defence-oriented rebuttal, and a blame-oriented rebuttal in their modeling activity. The elaboration-oriented rebuttal interspersed with negative epistemic affect was used to elaborate on a student's explanation, and a negative epistemic affect was elicited from their cognitive discrepancy. On the other hand, defence-oriented rebuttal and blame-oriented rebuttal entangled with negative epistemic affect were used to defeat the students rather than help rigor evaluation of students' explanation, and the negative epistemic affect was elicited from the other students' undesirable behavior. These results suggest that students' rebuttals can be elicited by epistemic dynamics related to the epistemic affect. The study shows that if negative epistemic affect were elicited from the other students' naive or false explanations, such an emotion is natural in terms of model construction, and the model can be further developed through the acceptance of the elaboration-oriented rebuttals by students' emotion regulation. In addition, we suggest that negative emotions aroused from the worsening of relationships during small group modeling activities are difficult to regulate and can have negative effects on students' cooperative model construction.

The purpose of this study is to develop MICHS(Models of Interactive Cyber Home Study) for effective cyber home study(CHS) and a prototype system to support realtime and non-realtime interaction tools such as chatting with users, to study a method to connect MICHS with selective curriculum, and to verify the educational effect of the model. MICHS consists of two models. One model is an educational system model, and another model is a teaching-learning model. The major results of this study are summarized as follows. In the viewpoint of learning achievement, there is no significant difference in achievement between the experimental group(33 leaners) and the comparative group(33 leaners), but this fact can be construed as the possibility that CHS is an alternative system of school education. The interests on CHS of learners in the experimental group were increased twice. This result means that the system of CHS for active interaction needs various and important interaction tools, and the educational vision of CHS. In the viewpoint of system operation, CHS needs higher system requirements such as 100 Mbps Fast Ethernet. If an old system can not process streaming services in request, it should be upgraded to a new system.

Purpose : This study aimed to examine the causal relationships among knowledge, stigma prejudice, attitude, social interaction which are factors affecting the Nursing Intention for AIDS patients. Method : Data were collected from June 20 to August 10, 2012, 268 nurses in general hospital located in and outside of Seoul, who were selected using convenience sampling. For hypothesis testing, the collected data were analyzed using AMOS 19. Results : Analysis of the path coefficients in this study showed that 41% of the variation in Nursing Intention could be explained by variation in the model. Social Interaction and Attitude directly affected the Nursing Intention. Social Interaction was found to be the most important predictive factor to explain Nursing Intention. Conclusion : This study found that there are need to increase possibility of social interaction and make positive changes in attitude toward AIDS patient care in order to improve Nursing Intention.

Family tourism has become the mainstream demand of the tourism market, and it is also an effective way to obtain happiness. This paper takes family tourists as the research object, takes the family tourism family affection interaction behavior and the experience value relationship as the link, Empirically tests the family tourism "interaction behavior-social support-experience value" conceptual model and the relationship hypothesis. The results showed that interaction of family affection had a positive and significant effect on the functional, cognitive and emotional experience value of family tourists. Family interaction in family tourism has a significant positive impact on social support. Social support has significant positive effects on functional, cognitive, emotional and overall experiential values. This conclusion expands the theoretical and empirical research on the relationship between interaction behavior and experience value, and provides a basis for understanding the interaction behavior and experience value of family love from the perspective of tourism experience essence.
