  • This paper proposes a self-organizing fuzzy modeling which can create a new hyperplane-shaped cluster by applying multiple regression to input/output data with relatively large fuzzy entropy, add the new cluster to fuzzy rule base and adjust parameters of the fuzzy model in repetition. Tn the coarse tuning, weighted recursive least squared algorithm and fuzzy C-regression model clustering are used and in the fine tuning, gradient descent algorithm is used to adjust parameters of the fuzzy model precisely And learning rates are optimized by utilizing meiosis-genetic algorithm. To check the effectiveness and feasibility of the suggested algorithm, four representative examples for system identification are examined and the performance of the identified fuzzy model is demonstrated in comparison with that of the conventional fuzzy models.

  • This study aims to uncover what kinds of difficulties preschool teachers are now confronted with when they begin to implement project based learning with young children, in order to develop contents for teacher education programs. From July 2012 to February, 2013, 9 teachers participated in implementing projects in preschool classrooms. For data generation and interpretation, observations of class projects, tape-recordings of teacher conferences, and interviews with the teachers were made. The findings were as follows: teachers' uncertainty regarding project itself, teachers themselves, child competence, and its sustainableness were the most critical obstacle to hinder the teachers in implementing self directed projects with young children. The results imply that the teachers' belief in child competence in doing projects is of great significance; their view that it is very difficult for them to do projects without viewing young children a co-constructor of knowledge. Therefore, the key element in developing contents for teacher education programs should include a richer understanding of young children' competence.

  • Purpose: The purpose of this study was to explore and describe healing effects of the forest on alcoholics through a forest experience program. Methods: The qualitative data was gathered from one focus group discussion with 6 alcoholics and individual interviews with 8 alcoholics. They had all participated in a "healing forest" program. All interviews were recorded and transcribed according to thematic content analysis processes. Results: The four main themes on the attributes of forest were "a lively living being", "placidity and tranquility", "acceptive atmosphere", and "beautifulness as it is" which revealed the participants' perceived nature of the forest which was attributed to the healing effects. Eight other themes on participants' positive changes included "revived senses", "aspired to live", "relieved and relaxed from being tense", "gaining insight on self", "having an acceptive attitude", "becoming compliant with his/her life", "learning that life is being together" and "recognizing the value of one's existence". Conclusion: The findings of the study illustrated the participants' self-healing processes through interactions with the nature of the forest. Nursing interventions utilizing healing atmospheres such as "healing forest" programs can be considered helpful in providing a venue to alcoholics to reflect on their lives affirmatively.

  • The purpose of this study is to investigate mothers' beliefs regarding children's literacy development and self-reported home literacy practices with their children. The instrument used for this study measured mothers' beliefs toward the whole language approach against the traditional approaches in children's literacy development. The total number of 340 mothers participated in this study who are sending their children to daycare centers of kindergartens in Seoul and its suburban area. Mean, Standard Deviation, frequency, Spearman's rho, and Kendall's tau were employed to analyze the data. The results showed that mothers' beliefs on the whole language approach have relationships with their home literacy practices, and their demographic characteristics - such as mothers' education, their spouses' education, and income - were also related with mothers' beliefs. The results of this study explore the inter-relationship of mothers' beliefs with home literacy practices, and also the importance of mothers' belief system on children's literacy learning at home.

  • This plan was submitted as part of an invited competition for the provincial park planning of Yeonin Mountain, which was held by the Gyeonggi Innovation Corporation in November, 2006. The proposed site is located at Seungan-ri, Gapyung-eup, Gapyung-gun, Gyunggi-do and covers about $150,010m^2$. The main goal of this project is to "Suggest a New Park Paradigm" by shedding old ways of thinking about parks through an integrated development concept. Planning was approached as follows: First, providing an unique theme to the support facilities area of Yeonin Mountain Piovincial Park. To achieve this theme, the Seungan support facilities area was designated to be home to a Seven Colored Theme Garden, currently named the Native Wild-flower Garden, while the Baekdun facilities area is to be centered on a Self-loaming Forest Camp, which will give the chance of a hands-on wildlife experience. With these themes, which create recreational goals that will encourage not only tourism but education as well, the foundation was laid for a multi-purpose park paradigm. Second, Developing a Core Facility Zone. To accomplish the development of a core facility zone, park buildings will be arranged in accordance with an integrated building lay-out for easy access and use, and the facilities specified by design for the Seven Colored Theme Garden are provided for the newly prepared site. This will allow focus on the user's viewpoint instead of the view of the planner or of ease of maintenance.

  • Training a statistical model for semantic role labeling requires a large amount of manually tagged corpus. However. such corpus does not exist for Korean and constructing one from scratch is a very long and tedious job. This paper suggests a modified algorithm of self-training, an unsupervised algorithm, which trains a semantic role labeling model from any raw corpora. For initial training, a small tagged corpus is automatically constructed iron case frames in Sejong Electronic Dictionary. Using the corpus, a probabilistic model is trained incrementally, which achieves 83.00% of accuracy in 4 selected adverbial cases.

  • We propose a two-stage document layout segmentation method. At the first stage, as top-down segmentation, morphological distance map algorithm extracts a collection of rectangular regions from a given input image. This preliminary result from the first stage is employed as input parameters for the process of next stage. At the second stage, a machine-learning algorithm is adopted RBF network, one of neural networks based on statistical model, is selected. In order for constructing the hidden layer of RBF network, a data clustering technique bared on the self-organizing property of Kohonen network is utilized. We present a result showing that the supervised neural network, trained by 300 number of sample data, improves the preliminary results of the first stage.

  • Genetic algorithm is used as a means of search, optimization md machine learning, its structure is simple but it is applied to various areas. And it is about an active and effective controller which can flexibly prepare for changeable circumstances. For this study, research about an action base system evolving by itself is also being considered. There is to have a problem that depended entirely on heuristic knowledge of expert forming membership function and control rule for fuzzy controller design. In this paper, for forming the fuzzy control to perform self-organization, we tuned the membership function to the most optimal using a genetic algorithm(GA) and improved the control efficiency by the self-correction and generation of control rules.

  • Background: The objective of this study was to assess the readability, suitability, and health content of cancer screening information in municipal newspapers in Japan. Materials and Methods: Suitability Assessment of Materials (SAM) and the framework of Health Belief Model (HBM) were used for assessment of municipal newspapers that were published in central Tokyo (23 wards) from January to December 2013. Results: The mean domain SAM scores of content, literacy demand, and layout/typography were considered superior. The SAM scores of interaction with readers, an indication of the models of desirable actions, and elaboration to enhance readers' self-efficacy were low. According to the HBM coding, messages of medical/clinical severity, of social severity, of social benefits, and of barriers of fear were scarce. Conclusions: The articles were generally well written and suitable. However, learning stimulation/motivation was scarce and the HBM constructs were not fully addressed. Practice implications: Articles can be improved to motivate readers to obtain cancer screening by increasing interaction with readers, introducing models of desirable actions and devices to raise readers' self-efficacy, and providing statements of perceived barriers of fear for pain and time constraints, perceived severity, and social benefits and losses.
