In this paper, we propose Genetic Algorithms(GAs)-based Optimized Polynomial Neural Networks(PNN). The proposed algorithm is based on Group Method of Data Handling(GMDH) method and its structure is similar to feedforward Neural Networks. But the structure of PNN is not fixed like in conventional neural networks and can be generated in a dynamic manner. As each node of PNN structure, we use several types of high-order polynomial such as linear, quadratic and modified quadratic, and it is connected as various kinds of multi-variable inputs. The conventional PNN depends on the experience of a designer that select the number of input variables, input variable and polynomial type. Therefore it is very difficult to organize optimized network. The proposed algorithm leads to identify and select the number of input variables, input variable and polynomial type by using Genetic Algorithms(GAs). The aggregate performance index with weighting factor is proposed as well. The study is illustrated with tile NOx omission process data of gas turbine power plant for application to nonlinear process. In the sequel the proposed model shows not only superb predictability but also high accuracy in comparison to the existing intelligent models.

Informal engineering education program for high school students was developed to cultivate engineering literacy using the human resources and facilities of university. Plant factory, a smart farming technology, was selected as a main theme, and the novel engineering camp program involving engineering design activities and intra-linter-team works was planned. The camp program was applied to 38 high school students in an active learning classroom. Five teams were constructed according to elemental technologies such as biotechnology, information-communication technology, energy engineering, mechanical engineering and architectural engineering, and the students were participated in intra- and inter-team activities to achieve the final goal of 'the construction of a plant factory in school'. The team works were conducted according to the eight steps of engineering design process (identifying the problem and need, identifying criteria and constraints, brainstorming possible solutions, selecting the best possible solution, constructing a prototype, testing and evaluating the solution, communicating the solution, and refining design). Participants' satisfaction survey showed that the satisfaction on the contents of engineering design was 4.48 on 5-point Likert scale. The participants' satisfaction on creative activity and systematic methodology was 4.43 on 5-point Likert scale. 97% of participants responded positively to team works, and 92% of participants were satisfied with career mentoring activity supplied by undergraduate/graduate students. These results indicates that the engineering camp program involving engineering design activity and intra-/inter-team works can contribute to cultivate engineering literacy such as creativity, problem solving ability, collaboration, communication skills for high school students, and to increase their interests in engineering fields.

This study aims to explore the effects of the parenting education program for high-school maladjusted students. To this purpose, a parenting education program for adolescents developed by the Ministry of Gender Equality and Family(MOGEF) was applied to ten high-school maladjusted students in an alternative(Dae-an) class in Jeju. Findings from class observations and interviews with participants are as follows. First, students with school maladjustment recognized importance and necessity of positive self-concepts and had an opportunity for self-growth through parenting education program. Second, students with school maladjustment obtained understanding about their family of origin and confidence for forming their future families. Third, advance learning about meanings and roles of being a parent provided students with opportunities to know importance of responsible sexual behavior. Fourth, practices of basic care with a replica of a new-born baby enhanced participation and concentration level of students with school maladjustment which became extremely effective in obtaining necessary knowledge for the basic care. Fifth, information provision for parent roles according to children's different developmental levels let students recognize that parent's roles change as their children grow and opened a way to grasp the need of parent education. Sixth, education and repetitive practices on reflective listening helped students enhance communication skills which entailed expanding their human relations. Seventh, passing-down of emotion and understanding on child abuse allowed students recognize risks of child abuse as well as the importance and need of skills for controlling emotion. This study sheds lights on the feasibility and effectiveness of a parenting education program for maladjusted or vulnerable students as an effective program for school drop-out prevention.

This paper aims to identify the relationship between the number of teeth of the elderly and their life happiness index. A face-to-face interview survey was conducted with elderly residents of Dong-gu, Daejeon from June 27 to July 25, 2012. A Tukey post hoc test and correlation analysis were implemented after a t-test and variance analysis. The results of analysis showed that satisfaction with life related to oral health was significant, but happiness in daily life had no significant difference. For the elderly, the quality of life related to oral health and happiness in daily life had no significant difference. Masticatory performance difference depending on usage of dentures also showed significant difference (p<0.001). The difference of masticatory performance depending on the number of teeth was analyzed by a correlation analysis. The present number of teeth, present anterior teeth and molars demonstrated a correlation. Quality in life related to oral health depending on the number of teeth correlated with the present number of teeth, present anterior teeth and present molars.

Cryopreservation induces sublethal damage to the spermatozoa, which leads to their reduced fertile life. The objective of this study was to investigate the effect of taurine, hypotaurine and trehalose as antioxidants on the function of the freezing-thawed sperm in Korean Jeju Black Bull. The semen was cryopreserved with tris egg yolk extendercontaining 7% glycerol and treated with 20mM taurine, hypotaurine and trehalose. Frozen-thawed sperms were evaluated for sperm motility, viability, membrane integrity, acrosome integrity and sperm penetration ability. The results were compared to semen cryopreserved in tris egg yolk extender containing 7% glycerol only as control. Frozen-thawed semen evaluation clearlyindicated that the addition of taurine or hypotaurine significantly improved (p<0.05) the motility and viability compared to control spermatozoa. Moreover, in membrane integrity, swollen sperm ratio was significantly increased (p<0.05) in taurine, hypotaurine or trehalose compared to control. In sperm acrosome integrity, F pattern ratio was increased (p<0.05) in hypotaurine among treatments, and AR pattern was significantly lowered (p<0.05) in taurine, hypotaurine and trehalose. In assessed sperm fertilizing ability, taurine, hypotaurine or trehalose significantly improved (p<0.05) the ratio of pronucleus formation and SFI. Finally, compared with the control, addition of taurine, hypotaurine or trehalose as an antioxidant to the freezing extender showed more positive effects on the frozen-thawed spermatozoa. It is concluded that the addition of taurine, hypotaurine, or trehalose to the freezing extender could reduce cryodamage of the Korean Jeju Black Bull spermatozoa.

This study was carried to improve the facilities in Daegu Kyungpook public Arboreta. On the basis of visitor's performance, satisfaction and implicitly derived importance, this study conducted Revised Importance- Performance Analysis, Exploratory Factor Analysis and Regression Analysis between extracted performance factors and overall satisfaction. As a result, 'Plant and Arboretum's Landscape' factor was seemed to affect overall satisfaction quite a bit and need to keep up the good work because the attributes belonged to this factor had high importance-performance in Daegu Arboretum. The attributes located in 2 quadrant and had a relatively large effect on overall satisfaction were 'Management of information board', 'Capacity of restroom' and 'Accessibility to restroom' in Daegu Arboretum. These attributes are needed to be improved as soon as possible. Kyungpook Arboretum also had similar results in 'Plant and Arboretum's Landscape' factor but 'Parking Lot' factor was more influential to overall satisfaction compare to Daegu Arboretum. Especially, 'Capacity of parking lot' attribute, one of 'Parking Lot' factor, was the first one to be improved because it had high importance and low performance.

We have to consider two parts of the evaluation and treatment for the patients with head and neck burns. The primary consideration is swallowing function for nutrition supply for them and the next is speech function for efficient communication and aesthetic impression of them. The purpose of this study is to summarize the preliminary questions of Communication Screening Protocols which can help understand comprehensively on swallowing disorder, motor speech disorder and voice disorder of patients with head and neck burns. We divided the evaluation into 4 evaluation areas including 'oral mechanism', 'respiration/voice', 'articulation', and 'swallowing' by referring to overseas studies dealing with various communication disorders caused by burns, and prepared the final questionnaires by conducting the content validity verification by five expert (speech & language pathologist). The range of Content Validity Index was shown relatively appropriate with .50~.84. There was a conflict of opinions in experts whether the items in the areas of respiration/voice and swallowing may be appropriate, whereas there was no different view of the oral mechanism and articulation area. Through the different characteristics of communication difficulties of patients with head and neck burns, we expect it will be modified appropriately according to the patients through evaluation of burn patients by type and severity.
