  • This study investigated the relationships between verbal behaviors and chemistry problem solving ability in cooperative learning. Based on the previous chemistry achievement. 11th-graders were assigned heterogeneously into three-membered groups. Small cooperative group problem solving processes in using 4 stage-problem solving strategy were audio/video taped. Students' chemistry problem solving ability was then measured by a problem solving strategy performance test. Their verbal behaviors were classified into giving information, receiving information, asking questions, and disagreeing. These were further coded into 16 subcategories. Providing, a subcategory of giving information, was the most frequent behavior. In studying partial correlation between verbal behaviors and problem solving ability, 7 categories were found to have significantly positive relationships. Providing showed the highest correlation with the problem solving ability as reported previously. Moreover, this study also revealed significant correlations in the categories of clarifying provided, correcting, justifying, and clarifying. In the case of low-ability students, the verbal behaviors of giving or receiving information were strongly correlated with problem solving ability. However, these verbal behaviors did not enhance the problem solving ability of high- and medium-ability students.

  • The competition between countries became internationalized in the market. However, a situation in which globalization is concerned is important to domestic corporates. Corporate strategy to survive in the domestic market are also juggling the limit of survival. Technology transfer and commercialization at this point has important implications now. The same applies to the national level. Public-to-private technology transfer has been more important, in order to overcome the international competitions. Although various studies have been made to promote technology transfer, in the livestock sector rarely attempted. Taking into account that few previous research and theory development has been achieved, the paper explored the technology transfer phenomenon in the sector employing the grounded theory approach by Strauss & Corbin(1998). Corporates that licensed in technologies through the Foundation of Agri. Tech. Commercialization & Transfer, were targeted as informants or interviewees. Finally, eight informants were selected sequentially utilizing theoretical sampling technique to the saturation point. As the result of open coding and axial coding of the interview data using NVivo10 by QSR International, 77 concepts, 20 sub-categories, and 7 categories were derived while paradigm model was established. Through selective coding, 'the factors affecting technology transfer in livestock sector' was identified as core category. The story line about the core category was developed based on four main categories. Finally, it is expected that the concepts, categories, and the relationship between them can be an important basis for further research.

  • The literature has reported that hierarchical classification methods generally outperform the flat classification methods for a multi-class document classification problem. Unlike the literature that has constructed a class hierarchy, this paper evaluates the performance of hierarchical and flat classification methods under a situation where the class hierarchy is predefined. We conducted numerical evaluations for two data sets; research papers on climate change adaptation technologies in water sector and 20NewsGroup open data set. The evaluation results show that the hierarchical classification method outperforms the flat classification methods under a certain condition, which differs from the literature. The performance of hierarchical classification method over flat classification method depends on class similarities at levels in the class structure. More importantly, the hierarchical classification method works better when the upper level similarity is less that the lower level similarity.

  • The purposes of the study were to analyze pre-service mathematics teachers' MKT and to examine the perceptions of MKT to find implications for the improvement of pre-service mathematics teacher education program in the aspect of teachers' content knowledge. Twenty-six pre-service mathematics teachers participated in the survey to examine the perceptions of MKT and they also finished two MKT tasks which focused on a specific area of middle school geometry. According to the survey results, the participants thought that they have enough knowledge in all categories of MKT except KCT-2 and they appreciated the importance of MKT education in pre-service mathematics teacher education program. However, the participants showed difficulties in MKT task items which required SCK, KCS, KCT, especially, the proportions of those who showed appropriate knowledge on the items required SCK and KCT was less than 50%. These results show disagreement between the perceptions of pre-service mathematics teachers' MKT and practice of MKT.

  • Many disaster management actors participate in the disaster sites and they do their best for the best result in their given position. They recover the disaster-stricken area, endeavor to prevent the disaster's relapse, and to rescue and protect the disaster victims. Ultimately, the purpose of their role and effort is to support a physical aid as well as material aid for that disaster victims can return their living condition to the original one before the disaster. However, the disaster management services have been provided in the supplier's view till now. Subsequently, despite significant efforts, providers have failed to comprehend what would be the victim's demand and how to reflect that in the disaster management service. In this paper, we approached and analyzed the recent disaster management service in the way of grounded theory, and endeavored to find the solution which disaster victims preferred. As a result of analysis, we found 184 concepts, 28 sub-categories, and 9 categories which could explain the victims' desired solution. We found that "an imperfect restoration which causes disaster" and "pain of the disaster field" would be main categories among them.

  • The purpose of this study is to examine how the long-term care effects the elderly that adapt themselves to the caring facility, what their experiences are and what kinds of behavioral characteristics they present. We have analyzed the research conducted on 15 elderly individuals who are living in an elderly long-term care facility, by using the grounded theory approach of Strauss and Corbin (1998). As a result, 170 concepts, 42 sub-categories, and 15 categories were set by the open coding process. During the adaptation process in a long-term care facility, the primary experience or feeling by the elderly is that they had been 'deserted'. However, when consolidating the casual conditions, contextual conditions, intervening conditions, the action/interaction strategy, and consequence, the primary experience was that the elderly came to an 'acceptance'. Such acceptance was then sub-categorized into a destiny-resignation type, reality-acceptance type, and voluntary-selection type. Based on the results of this study, we recommend practical alternatives which will improve surrounding circumstances including caring facilities, its employees, relationships with other elderly individuals, and family support.

  • This study applied hermeneutic grounded theory suggested by Rennie to understand general meaning of adoption decision process of 7 non-married mothers. At the end of the analysis, 191 meaning units, 46 subcategories, and 11 hermeneutic categories were constructed. The core category that threads throughout the adoption decision process was represented as "living with a scar left by the duality of motherhood; repudiating and embracing." The adoption decision process emerged as recognition of pregnancy, avoidance of reality, searching for adoption, escalation of confusion, determination and rationalization or forfeiture. Based upon our research, we suggested that the adoption decision process of non-married mother was another way of practicing motherhood, and we proposed that we need to develop a psycho-social support program to improve the lives of non-married mothers.
