Objectives: The purpose of the study is to investigate the academic achievement in comprehensive dental hygiene courses using MBTI personality type. This study will provide the various pedagogical approaches in the dental hygiene education. Methods: A self-reported questionnaire was completed by 58 dental hygiene students in Chungnam from December, 2012 to March, 2014. The questionnaire consisted of academic achievement of comprehensive dental hygiene course and communication skills, After filling out the questionnaire, the students completed MBTI personality type sheet. Results: The students were categorized as extroversion type (58.6%), sensing type (70.7%), feeling type (56.9%), and perceiving type (67.2%). In the academic achievement, extroversion and judging personality type students had higher self-efficacy than the students of introversion and perceiving types. The extroversion personality type students also had the higher assignment level and confidence than the introversion type. Conclusions: In order to enhance the understanding and learning capacity of the students, dental hygiene professors should understand the differences in achievement levels due to different personality types so that they can utilize better pedagogical approaches.

Purpose:The present qualitative study explored adolescents' perceptions regarding effective strategies to prevent adolescents from using tobacco products (TP). Apart from the commercial TPs, there has been emerging use of alternatives such as vapes, e-cigarettes and shisha. This unfortunate phenomenon continues despite the currently available preventive strategies. Thus, understanding of the perceptions of the current generation would be valuable to provide new insights. Methods: Purposive sampling was utilized to recruit 40 adolescents between the age of 15 and 16 years old attending public daily secondary schools. Eight focus group discussions were conducted among the TP users, ex-users and non-users. Data were analyzed using a thematic content analysis procedure with NVivo. Results: Among barriers with the currently available strategies were having teachers who smoke tobacco, addiction to nicotine and self-perceptions of being healthy. The content of any program should include knowledge on negative outcomes of using tobacco products and awareness of the legislation together with ways to overcome peer and family influence including improving self-efficacy and refusal skills. Strategies were suggested to be delivered using information technology which provides interactive learning and visual effects. Conclusions: Adolescents agreed that the content and delivery of tobacco use prevention strategies need to be revised to suit the current generation to ensure sustainability.

The main aim of this study is to predict the compressive and flexural strengths of self-compacting mortar (SCM) containing $nano-SiO_2$, $nano-Fe_2O_3$ and nano-CuO using wavelet-based weighted least squares-support vector machines (WLS-SVM) approach which is called WWLS-SVM. The WWLS-SVM regression model is a relatively new metamodel has been successfully introduced as an excellent machine learning algorithm to engineering problems and has yielded encouraging results. In order to achieve the aim of this study, first, the WLS-SVM and WWLS-SVM models are developed based on a database. In the database, nine variables which consist of cement, sand, NS, NF, NC, superplasticizer dosage, slump flow diameter and V-funnel flow time are considered as the input parameters of the models. The compressive and flexural strengths of SCM are also chosen as the output parameters of the models. Finally, a statistical analysis is performed to demonstrate the generality performance of the models for predicting the compressive and flexural strengths. The numerical results show that both of these metamodels have good performance in the desirable accuracy and applicability. Furthermore, by adopting these predicting metamodels, the considerable cost and time-consuming laboratory tests can be eliminated.

This paper proposes a type of self organizing neural network which recognizes arbitrary symbols as well as numerical or alphabetic characters. The proposed algorithm autonomically organizes and classifies similar patterns on the basis of the distribution types of characteristics in the input images. Thus it can be appliced for the recognition of arbitrary images when it is difficult to establish a learning rule. It performs a stale recognition process with in the limit of the memory capacity. The cheme was applied and tested to 50 different image patterns with increased noise level up to 44%(SNR 2dB). The implementation results demonstrate that the proposed algorithm successfully recognizes the image patterns changed due to the various noise levels and thus proves excellent antinoise characteristics.

Based on Perceptions about Mathematics Teachers (PMT) perceived by high school students, measured by 2189 students from Seoul Educational Longitudinal Study 2014 (SELS 2014), latent profile analysis (LPA) identified five distinct types of student groups (positive, partial positive, middle, negative, extreme negative). These student of positive, middle, and negative groups are positive, moderate and negative perceptions about math teachers. Partial positive group generally had a positive perception about mathematics teachers, extremely negative group was very negative about mathematics teachers. Both of these groups had peculiarly inconsistent trends and several anomalies. The Multinomial logistic regression analyses also indicated that individual factors (gender, major, self-concept, resilience, self-assessment, career maturity), school factors (friendship, relationship with school teachers) and parental factors (academic-relationship, emotional-relationship) were significant predictors of PMT profile groups. The Analysis of variance also indicated that mathematics class (attitude, satisfaction and atmosphere), Mathematics achievement were significant predictors of PMT profile groups. The profiling of perceptions about mathematics teachers resulted in enhanced understanding of the complex range of processes students employed. During mathematics class, implementation of smooth interactions and communications between students and teachers added in the teaching and learning of mathematics.

The purpose of this study was to examine the influence of father's characteristics on the creativity of gifted preschoolers and nongifted preschoolers. Father's personality, creative personality and parenting self-efficacy were included in father's characteristics. The study subjects were 96 gifted and 180 non-gifted preschoolers and their fathers. Instruments were the Torrance Test of Creative Thinking(Torrance, 1984: Kim et al., 2002), Revised NEO-Personality Inventory(Costa & MaCrae, 1992), What Kind of Person Are You Scale of the Khatena-Torrance Creative Perception Inventory(Khatena & Torrance, 1976: Kim et al., 2004), and Parenting Efficacy Scale(Choe et al., 2001). The results showed that extroversion, healthy ability and disciplined ability of the gifted preschoolers' fathers influenced the children's fluency of creativity, while the disciplined imagination of gifted preschoolers' fathers influenced children's elaborateness of creativity. Regarding non-gifted children, the intimacy of the non-gifted preschoolers' fathers influenced the children's fluency of creativity, the general parenting ability of non-gifted preschoolers' fathers influenced children's abstractness of titles of creativity, the general parenting ability of non-gifted preschoolers' fathers the influenced children's elaborateness of creativity, and general parenting ability and learning guidance ability of non-gifted preschoolers' fathers influenced the children's resistance to premature closure of creativity.

This study was designed to compare general characteristics and dietary habits between volunteers for a nutrition survey and non-volunteers using a questionnaire. Volunteers were recruited by advertising on the homepage of a university to assess nutritional status by examining dietary intake for three days and blood analysis. Non-volunteers were selected from some classes not related to nutrition. There were no significant differences in sex, monthly allowances, eating-out cost, drinking and exercise between the two groups, while the proportion of self-boarding was higher in the volunteer group than in the non-volunteer group, and smoking rate of volunteers was approximately 2.4 times lower than that of non-volunteers. Volunteers were less concerned about their diet than non-volunteers. No significant differences in concern about health, considering factors in their diet, self-evaluation of their diet, learning experience about nutrition, and vitamin/mineral supplement use were observed. The frequency and the place of eating-out for dinner were significantly different between the two groups. More proportions of volunteers tended to eat regularly and eat breakfast. Volunteers consumed seaweeds more frequently, and milk, fruits and fast foods less frequently than non-volunteers. Our results indicate that some characteristics and dietary habits of volunteers are different from those of non-volunteers. However, we could not show that volunteers were more interested in their diet and had desirable dietary habits than non-volunteers. Further research on the characteristics of volunteers who participate in nutrition survey may be helpful to interpret and generalize the survey results.

Purpose: This study was done to develop a web-based education program for nurses working in nursing homes. The focus was on the rights of older adults. Methods: The program was designed based on the Network-Based Instructional System Design (NBISD) model and was operated and evaluated between July 2007 and June 2008. Results: Out of nursing records of 40 residents from a nursing home, the final 7 cases were deducted through classification using the Resource Utilization Group (RUG)-III. The data on needs for education was collected from 28 nurses working in 15 nursing homes located in Seoul and Gyeonggi Province, who agreed to complete a self-report questionnaire. A comprehensive review of the literature and two focus groups interviews were used to search for risk factors and guidelines for protection of human rights. The education program was developed based on Kolb's experiential learning model and composed of 5 units, which included content on types of human rights and rights to death with dignity, elder abuse, physical liberty, and self-determination. The program was positively evaluated showing a score of 3.35 (SD=0.37) out of 4. Conclusion: The educational program developed in this study should promote nurses' sensitivity to the rights of elders and improve nurses' behaviors in protecting the rights of elders residing in nursing homes.
