With rapid development of various information and communication technologies, to forecast future became important for coping with new environment. Experts in each field of study are forecasting future society, and considerable life scenarios are derived in the process. Life scenarios help people to approach and understand future circumstances easily. Therefore, to study future housing with life scenarios as materials will be helpful to establish the direction to the development of current housing. The purpose of this research is to examine what characterizes the housing functions and life behaviors of future house and what is changing from the housing functions and life behaviors of past and present. Content analysis was used as research method. The subject was 10 future forecasting books which reflects daily life in the house, and 1 episode relating residential space as 1 analysis unit, the total of 213 episodes were analyzed as materials. As a result, most of the life behaviors in the house are expected to be performed by robots instead of humans in the future. On the other hand, partial life behaviors are already being performed mostly by computer system, and another partial life behaviors show that the role-performance of them are not being totally by robots but partially with human.

In this paper, we propsoe a new method of th ecommunication system for cooperative behaviors and works in collective autonomous mobile robots. A communication function among the collective robots is essential to intelligent cooperative works. In genral, global communication is effective for small number of robots. However when the number of robot goes on increasing, this becomes difficult to be realized because of limited communication capacity and increasing amount of information to handle. And also the problems such as communciation interfeence and improper message transmission occur. So we propose local communication system based on infrared sensor to realize the cooperative behavior among robots as the solution of above problem. It is possible to prevent overflow of information and exchange of complex information by fusion sign board model which transmits the information to unspecified robots and message passing model which communicate a specific robot. And we formularize optimal communication range by analysis of information propagation mechanism from the proposed comunication system. At last we verify the effectiveness of the proposed communication system from example of cooperative works.

The purpose of this study was to develop a self-report scale measuring dysfunctional communication behaviors that Korean husbands and wives may use during marital fights. Based on the four concepts of criticism, contempt, defensiveness, and stonewalling proposed by Gottman(1994a), an initial pool of 38 items was developed. Through expert reviews of the 38 items to assess content validity, preliminary 30 items were selected. Using a sample of 89 married couples who were living in Susan, Korea, we conducted item analyses and exploratory factor analyses with the 30 items. These analyses yielded a final 19-item, four-factor scale : criticism(5 items), contempt(5 items), defensiveness(5 items), and stonewalling(4 items). The internal consistency estimates for these subscales were satisfactory. Finally, using another sample of 228 wives, we conducted confirmatory factor analysis to confirm cross validity of the 19-item, four-factor model. The result indicated that this model fitted the data reasonably well. All standardized factor loadings were significant in this model. The results of this study supported reliability and validity of this scale.

In this study, we consider the integration of cognitive components and emotion to account for communication behaviors and activism on a consumer advocacy website. The challenge of integrating situational theory and anger activism model was empirically explored utilizing an online survey with the members of the virtual community, which was designed to raise issues and to protest against the product defects of a product. Our findings indicated that along with the cognitive perception in the situational theory, anger as a negative emotion was the most significant predictor strongly associated with communication behaviors and activism on the organization. More interestingly, the model that integrates anger with cognitive components significantly improves its explanatory power compared with one including only cognitive components as explanatory variables.

Learning behaviors of a radial basis function network (RBFN) using a singular value decomposition (SVD) and stochastic gradient (SG) algorithm, together named RBF-SVD-SG, for odor sensing systems are analyzed, and a fast training method is proposed. RBF input data is from a conducting polymer sensor array. It is revealed in this paper that the SG algorithm for the fine-tuning of centers and widths still shows ill-behaving learning results when a sufficiently small convergence coefficient is not used. Since the tuning of centers in RBFN plays a dominant role in the performance of RBFN odor sensing systems, our analysis is focused on the center-gradient variance of the RBFN-SVD-SG algorithm. We found analytically that the steadystate weight fluctuation and large values of a convergence coefficient can lead to an increase in variance of the center-gradient estimate. Based on this analysis, we propose to use the least mean square algorithm instead of SVD in adjusting the weight for stable steady-state weight behavior. Experimental results of the proposed algorithm have shown faster learning speed and better classification performance.

The purpose of this study was to examine the relationship among infants' nonverbal communication, maternal verbal behaviors and the infants' acquisition of vocabulary. The subjects were 93 pairs of 10 to 18 months old infants and their mothers residing in the Seoul and GyeongGi-Do area. The results were as follows : (1) In terms of the infants' nonverbal communicative means, it appeared that the group of 16~18 month olds utilized more gesture and vocalization. As regards the infants' nonverbal communicative functions in terms of social behavior and joint attention, the group of 16~18 month olds was found to perform more of the behaviors from this category than the other groups. There was a significant difference in the maternal verbal behavior among the different age groups. (2) Among the infants' nonverbal communicative means, gesture and vocalization, there appeared to be a significant relationship between vocalization and the infants' acquisition of vocabulary. In addition, there was an important relationship between the high usage of infants' nonverbal communicative functions with behavior regulation and the high usage of joint attention and the successful acquisition of vocabulary among infants. (3) Social play, which is a maternal verbal behavior categorized as one of the strategies for getting infants' attention, was significantly related to the acquisition of infants' vocabulary. (4) When mothers used more imitating sounds and mimetic words, requests for information, descriptions, conventional social expressions, and imitation to enhance responsiveness, infants were found to have acquired a larger vocabulary.

This study practically analyzed the relationships of Internet addiction, self-esteem, interpersonal relations and maladjusted behaviors according to family types and in particular, made a practical analysis about whether self-esteem, interpersonal relations and maladjusted behaviors have mediation effects in the relationship between family types and Internet addiction. As a result of regression analysis, the Internet addiction according to family types was a negative relationship and significant. Family types were positively related to self-esteem. As for interpersonal relations, family types were significant as a positive relationship. On the other hand, maladjusted behaviors were proved that they have a negative relationship with family types like the Internet addiction. That is to say, even the mediation effects that family types through self-esteem, interpersonal relations and maladjusted behaviors related to Internet addition were verified. As a result, it was concluded that self-esteem, interpersonal relations and maladjusted behavior factors play mediator roles between family types and Internet addiction.

Objectives: The purpose of this study was to determine if self-rated oral health differed according to self-reported oral health behaviors in Korean adolescents. Methods: The raw data of 'The 6th Youth Health Behavior Online Survey' carried out by the Korea Center for Disease Control and Prevention were analysed. Independent t-test, one-way ANOVA, and Logistic regression analysis were used to assess the relationships between oral health behaviors and self-rated oral health (n=73,238). Results:Oral health behaviors had stronger influence on daily toothbrushing habits. In particular, participants who brushed their teeth in the morning and participants who brushed their teeth more than 3 times a day were more likely to have good self-rated oral (P<0.001). Conclusions: Korean adolescents with high self-rated oral health reported practicing good oral health behaviors. These results highlight the need for the further practicable oral health education programs.

Demand for appropriate health care has gradually increased in Korea. In addition, developments of community- and school-based oral health programs have also focused oral health care for the oral health promotion. Especially, school-based oral health programs are the underpinnings of promoting oral health and preventing oral diseases among schoolchildren. School-based oral health programs have had three major components: oral health education, oral health services, and a healthful environments. These included oral health education(one-to-one communication, group communication, and use of mass communication), oral examination, fluoride mouthrinsing, pit-and-fissure sealants, fluoride gel application, mechanical plaque control, and chewing xylitol candy. In this study, we evaluate the effects of oral health programs among primary schoolchildren by comparing the oral health knowledge, oral health behaviors, and perception of caries prevention procedures. Data for this study were obtained from 699 primary schoolchildren at the two primary school in Daegu, Korea. One is experimental group, N primary school, that was established school-based oral health center under supervision of Nam-gu Public Health Center, the other is control group, N' primary school, that was yet to establish school-based oral health center. We surveyed children's oral health knowledge and behaviors, and perception of caries prevention procedures using self-administrated questionnaire and then analyzed differences of each item among two groups. The brief findings of this study were summarized as follows. There are several advantage to a comprehensive school-based oral health program. (1) School-based oral health programs facilitate and increase the effectiveness of teaching oral health subjects. (2) Schoolchildren are available for prevention or treatment procedure. (3) School-based oral health center may be less threating than private dental clinic. (4) With comprehensive school-based oral health programs the decayed, missing, and filled teeth(DMFT) of schoolchildren should demonstrate a substantial and steady decrease over time(Choi et al, 2004). In conclusion, treatment is not the answer to solving children's oral health programs; rather primary prevention is the key. Many countries and communities are focusing on hoe millions of underprivileged children can be provided with health care. Schoolchildren gain the knowledge and behaviors to attain and maintain good oral health in schools. For these reasons, the role of school-based oral health center is not only important but also a necessity.

Purpose: The purpose of this study was to describe and to analyze real communication about a patient's discomfort between a patient with cancer and a nurse. Method: A dialogue analysis method was utilized. Fifteen patients and 4 nurses who participated in this research gave permission to be videotaped. The data was collected from January, 3 to February 28, 2006. Results: The communication process consisted of 4 functional stages: 'introduction stage', 'assessment stage', 'intervention stage' and 'final stage'. After trying to analyze pattern reconstruction in the 'assessment stage' and 'intervention stage', sequential patterns were identified. In the assessment stage, if the nurse lead the communication, the sequential pattern was 'assessment question-answer' and if the patient lead the communication, it was 'complaint-response'. In the intervention stage, the sequential pattern was 'nursing intervention-acceptance'. Conclusion: This research suggests conversation patterns between patients with cancer and nurses. Therefore, this study will provide insight for nurses in cancer units by better understanding communication behaviors.
