  • Fuzzy controller is one of the succeed controller used in the process control in case of model uncertainties. But it my be difficult to fuzzy controller to articulate the accumulated knowledge to encompass all circumstance. Hence, it is essential to provide a tuning capability. There are many parameters in fuzzy controller can be adapted, scale factor tuning of normalized fuzzy controller is one of the adaptation parameter. Two adaptation methods are implemented in this work on an experimental thermal process, which simulate heating process in liquefied petroleum gases (LPG) recovery process in one of petrochemical industries: Gradient decent (GD) adaptation method; supervisory fuzzy controller. A comparison between the two methods is discussed.

  • Speaker verification systems can be implemented using speaker adaptation methods if the amount of speech available for each target speaker is too small to train the speaker model. This paper shows experimental results using well-known adaptation methods, namely Maximum A Posteriori (MAP) and Maximum Likelihood Linear Regression (MLLR). Experimental results using Korean speech show that MLLR is more effective than MAP for short enrollment utterances.

  • Purpose: The purpose of this study was to explore and identify patterns from the phenomenon of the role adaptation process in elementary school health teachers and finally, suggest a model to describe the process. Methods: Grounded theory methodology and focus group interviews were used. Data were collected from 24 participants of four focus groups. The questions used were about their experience of role adaptation including situational contexts and interactional coping strategies. Transcribed data and field notes were analyzed with continuous comparative analysis. Results: The core category was 'establishing their own positions', an interactional coping strategy. The phenomenon identified by participants was confusion and wandering in their role performance. Influencing contexts were unclear beliefs for their role as health teachers and non-supportive job environments. The result of the adaptation process was consolidation of their positions. Pride as health teachers and social recognition and supports intervened to produce that result. The process had three stages; entry, growth, and maturity. Conclusion: The role adaptation process of elementary school health teachers can be explained as establishing, strengthening and consolidating their own positions. Results of this study can be used as fundamental information for developing programs to support the role adaptation of health teachers.

  • Purpose: The purpose of the study was to analyze the families values of the family with hospitalized children in order to offer descriptive data, which will facilitate family adjustment in those families. Method: It's intended in this study, as of descriptive approach, to verify the theoretical framework based on McCubbin's Resiliency Model and to examine the influence of family values on family adaptation. The survey was conducted from June 20, 2003 to November 30, 2003 and the analysis included 202 parents of the hospitalized children. The data analysis utilized SPSS 11.0 program. Result: The correlation coefficients among major variables showed that family stressor was positively related with family strains(r=.249, P<.01), and negatively related with family hardiness(r=-.183, P<.05). Family strains was negative related with general family value(r=-.243, p<.01), and family adaptation(r=-.505, P<.05). Correlations of general family value was positive with family hardness (r=.153, p<.05), and family adaptation (r=.200, p<.01). Conclusions: There was correlating relationship between family strains and family adaptation, and general family value showed correlation with family strains, family hardiness, and family adaptation. Theresfore the continuing future research on the relationship between family value and family adaption is necessary.

  • Purpose: As the proportion of foreigners participating in the domestic labor market is gradually increasing, problems caused by social and cultural differences have also been expressed. As such, the purpose of this study was to analyze the effects of organizational justice and social support on psychological and cultural adaptation and its effect on turnover intention. Research design, data and methodology: The data was collected for foreign workers who visited the Foreign Workers Support Center operated by the Korea Human Resources Development Service. A total of 224 data were analyzed from March 1 to March 30, 2019 and was analyzed through frequency analysis for basic work environment of foreign workers, factor analysis for reliability and validity of variables, and overall structural model analysis. Results: Organizational fairness did not appear to affect psychological adaptation and significant cultural adaptation but social support had a significant effect. Psychological adjustment did not affect turnover intention, and cultural adaptation had a significant effect on turnover intention. Conclusions: Thus, in order to reduce the intention of turnover and adapt well to the working environment, it would be more efficient to find ways to raise the level of psychological adaptation by strengthening social support rather than organizational fairness.

  • Purpose: This study was conducted to identify resiliency factor, to test causal relationship and effect of resiliency factors on adaptation in families of children with cancer. A conceptual framework was constructed based on McCubbin's resiliency model. Hypotheses were tested with empirical data. Method: Data were collected using self-report questionnaire from 232 families of children with cancer. The collected data were analyzed using the SAS program and LISREL program for covariance structural analysis. Result: Family hardiness and problem-solving coping had significant direct effects on adaptation in families of children with cancer. Social support had significant indirect and total effect on adaptation. Family Schema had significant direct effect on family hardiness and problem-solving coping. Problem-solving communication had a significant direct effect on family hardiness and an indirect effect on family functioning and problem-solving coping. Among the resiliency factors, family hardiness had the greatest effect on adaptation in family of children with cancer. Conclusion: The findings suggest that nursing interventions to enhance family hardiness, problem-solving coping and social support would result in an increase in adaptation in families of children with cancer. An integrated intervention that emphasizes and promotes resiliency factors should be developed and established for families of children with cancer.

  • Unsupervised domain adaptation often gives impressive solutions to handle domain shift of data. Most of current approaches assume that unlabeled target data to train is abundant. This assumption is not always true in practices. To tackle this issue, we propose a general solution to solve the domain gap minimization problem without any target data. Our method consists of two regularization steps. The first step is a pixel regularization by arbitrary style transfer. Recently, some methods bring style transfer algorithms to domain adaptation and domain generalization process. They use style transfer algorithms to remove texture bias in source domain data. We also use style transfer algorithms for removing texture bias, but our method depends on neither domain adaptation nor domain generalization paradigm. The second regularization step is a feature regularization by feature alignment. Adding a feature alignment loss term to the model loss, the model learns domain invariant representation more efficiently. We evaluate our regularization methods from several experiments both on small dataset and large dataset. From the experiments, we show that our model can learn domain invariant representation as much as unsupervised domain adaptation methods.

  • As abnormal climate phenomena occur more frequently due to climate change, damage which results from meteorological disaster increases accordingly and its scale and variety are becoming wider. This paper draws out planning and design elements and application techniques to build cities more adaptive to climate change from urban development cases in US and Europe. An urban model is suggested, that enables built environment to be more resilient to risks caused by climate change is applicable to urban development projects in practice.
