Objective : Aphasia interferes with communication between the patient and conversation partner. Adequate communication is essential not only for the patient but also for caregiver education and training Method : This study examined the benefits of parental education and group training in terms of improving the communication of six aphasic patients and their caregivers(family members). Caregiver education provided caregivers with information on stroke and aphasia, and group training was conducted according to the experimental learning cycle. Result : As a result, communication increased in terms of sending and receiving messages or interactive communication. Furthermore, the questionnaire analysis showed that caregivers learned more about aphasia and had confidence in using facilitation strategies. Conclusion : Giving educational opportunities to patients and caregivers promotes caregiver's knowledge and positively interacts.

The purpose of this study is to help a recovery of fatigue through the effect of cold immersion treatment after rowing ergometer on blood fatigue substance, MDA and SOD in rowing athletes. For this, 10 subjects participated in this study and we divided them into cold water immersion group (CWI, n=10), non-cold immersion group (NCI, n=10). The exercise program was performed to 2000 m rowing ergometer for maintaining high intensity. The data was collected with regard to the interaction effect of the group and time among the CWI and NCI, ANOVA was used. As the post-hoc test, Bonferroni test was used. The significance was set at .05 and the following conclusions were deduced. For lactic acid, there were the main effect of time (p<.001) and significant difference in the both group (p<.001). Also, LDH were significant difference in the each group (p<.05). For MDA, there were the interaction between group and time (p<.05) and the main effect of group (p<.05) and time (p<.001). SOD were indicated main effect of group and time (p<.05), there was significant difference between each group in the after 30 min recovery (p<.05). Collectively, The results of this study suggest that positive effect on blood fatigue substances, reactive oxygen species and anti-oxidation enzyme through cold water immersion intervention.

Electronic BBS (bulletin board system) Ins been widely recognized as an appropriate medium for exchanging ideas and sharing information asynchronously. The communication ability if BBS is the main reason for utilizing it as a tool for collaborative learning. Researchers in the community reported a number if findings regarding the educational utilization if BBS recently. In this paper, we propose a qualitative method to measure communication activities using BBS so that the complex discussion behaviors of participants can be understood analytically. We propose characteristic vectors to describe discussion behaviors of groups and individuals, which can be conveniently used for characterizing and comparing discussion groups as well as individuals. The interactivity model representing interactive activities shows graphically the degree of inter activity if discussion groups as well as individuals. Also, time dependent measurements are investigated to analyze discussion activities with time. Experiments on the proposed measurements conducted on the Web-based discussion project using BBS demonstrate how measurements can be carried out, how characteristic vectors and inter activity model can be constructed and used.

For the wide spread of cyber education, it is important to understand the instructional characteristics of cyber education and its applications in the educational sites which help to cope with the practical needs and problems. This study was conducted to analyze the experience of cyber classes(working hours, tasks and evaluation, satisfaction level and instructional effectiveness, suggestions for cyber education) and use of instructional methodology (instructional activities, interaction frequencies, cooperative learning activities, instructional activities toward knowledge building). The data was collected from pre-service teachers(403) and in-service teachers(318) in June 2004. The results were that pre-service and in-service teachers all consider the satisfaction level and academic achievement level of cyber classes lower than that of FTF classes. Particularly the boring presentation of instructional materials and the inadequate instructional strategies for cyber classes were the biggest complains, and lack of interaction among peer groups and with instructors, lack of learning opportunity for cyber instructional strategies, limited group activities, lack of interaction with experts were followed. Limited types of evaluation also showed that cyber classes focus on results more than the process of students' academic achievement.

The purpose of this study was to determine the effect of gait training based on the way in a speed pattern on the respiratory function of general adults. A total of 37 people were divided into three groups to conduct fast, standard, and interval gait training. For gait training, a treadmill was used. Three groups were trained for 60 minutes, three times per week, for a period of 6 weeks. Inspiration pressure, maximum inspiration volume, and the size of diaphragm movement were measured. Repeated Measures ANOVA was used to compare times, groups, and interactions. For inspiratory pressure, maximum inspiration volume, and size changes in diaphragm movement, there were significant differences depending on the time and interaction between times and groups. For size changes in diaphragm's movement, there was a significant difference between interval gait training group and standard gait training group. Therefore, interval gait training had effects on size changes in diaphragm movement.

분산 가상 환경(DVE)의 사용자 수가 증대됨에 따라, 고려해야 할 사항 중 가장 중요한 것들 중 하나는 상호작용의 성능을 위한 확장성에 있다. DVE의 확장성을 지원하기 위한 방법들 중 하나는 사용자 인지도 관리 기법이다. 기존의 인지도 관리 기법은 사용자의 인지도를 일정한 공간으로 제한을 함으로써 사용자가 받는 메시지의 수를 줄이는 방법이다. 하지만 많은 사용자들이 근접한 곳에 운집한 경우, 사용자는 그 근접한 공간에서 발생하는 모든 메시지를 받아야 한다. 이것은 사용자들에게 통신에 따른 많은 부하가 걸리게 되며 따라서 시스템은 확장성이 떨어지게 된다. 본 연구에서는 각 사용자의 인지도 영역에 사용자가 관심 있는 사물의 타입을 표현하고 같은 관심을 가지고 있는 사용자들끼리 그룹을 생성하여 사용자의 관심도에 따른 선택적인 메시지를 받게 한다. 이를 통하여 각 사용자는 자신과 근접한 공간에 있는 모든 사용자로부터 생성되는 모든 메시지를 받지 않아도 된다. 본 연구를 통하여 확장성 있는 방법으로 사용자간의 상호 작용을 지원할 수 있다.

Purpose: This study aimed to examine social networking service (SNS) use and recommended information utilization (SURU) according to the food-related lifestyles (FRLs) of consumers and analyze how the interaction between the FRL and SURU affects the practice of eating alone and visiting restaurants. Methods: Data on 4,624 adults in their 20s to 50s were collected from the 2021 Consumer Behavior Survey for Food. Statistical methods included factor analysis, K-means cluster analysis, the complex samples general linear model, the complex samples Rao-Scott χ² test, and the general linear model. Results: The following three factors were extracted from the FRL data: Convenience pursuit, rational consumption pursuit, and gastronomy pursuit, and the subjects were classified into three groups, namely the rational consumption, convenient gastronomy, and smart gourmet groups. An examination of the difference in SURU according to the FRL showed that the smart gourmet group had the highest score. The result of analyzing the effects of the FRL and SURU on eating alone revealed that both the main effect and the interaction effect were significant (p < 0.01, p < 0.001). The higher the SURU, the higher the frequency of eating alone in the convenience pursuit, and gastronomy pursuit groups. The main and interaction effects of the FRL and SURU on the frequency of eating out were also significant (p < 0.01, p < 0.001). In all the FRL groups, the higher the SURU level, the higher the frequency of visiting restaurants. Specifically, the two groups with convenience and gastronomic tendencies showed a steeper increase. Conclusion: This study provides important basic data for research on consumer behavior related to food SNS, market segmentation of restaurant consumers, and development of marketing strategies using SNS in the future.

It is very important to identify useful web user group and induce their behavior pattern in eCRM domain. Inducing user group with a similar inclination, a reliability of user group decreases because there is an uncertainty in online user data. In this paper, we have applied the 2-tier clustering, which uses the outcome of interaction with data from other tiers. Also we propose a method which induces user behavior pattern from a cluster and compare C4.5 with our method.
