Purpose: The purpose of this study was to contribute to enhancing elementary school health teachers professional job performance by analyzing their job identity and job stress. Methods: The participants were 138 elementary school health teachers registered at the Busan Metropolitan City Office of Education, and the survey was conducted from the 22nd to 23rd of July, 2010. The collected data were analyzed by percentile, t-test, ANOVA, Pearson's correlation coefficient, and stepwise multiple regression using the SPSS/WIN 17.0 program. Results: The average percentiles of job identity and job stress were 70.6 and 64.0 respectively. Among the sub-factors of job identity, autonomy was highest as 73.5, and among the sub-factors of job stress, job demand was highest as 73.9. There were significant differences in the degree of job identity and job stress according to education status, the number of classes, job satisfaction, enthusiasm for work, and the image of nursing teachers expressed in a word. The regression model explained 21.2% of the variance of job identity. job stress explained 32.0% of the variance. Conclusion: It is important to develop various comprehensive programs for improving job identity and managing job stress. In addition, it is necessary to provide support systems including persons, promotion and rewards to school health teachers.

The aim of this study was to find out the effect of instruction with storytelling on the achievement, attitude and interest in science. For this study, two classes were divided into experimental class and comparative class. All the results were analyzed quantitatively. Results of this study can be described as follows. First, the experimental class didn't have a significant difference in scholastic achievement compared with the comparative class. However, the results of the t-test for the academic achievement due to achievement level showed a positive effect in the average level of students. And experimental group was statistically significantly higher in the section of 'Combustion and Extinguishment' than that of the other group. Second, There was a significant difference in the aspect of the effect of instruction with storytelling on the student's science-related attitudes. As a result of analysis by sub categories of science-related attitudes, storytelling was effective in attitude toward science, but no significant differences were found in scientific attitude. Third, instruction with storytelling didn't show a meaningful difference in scientific interest. However, in the sub-part, they showed a meaningful improvement in attention and satisfaction.

Purpose: This study was done to assess the personal experiences of the coping process during pregnancy for single mothers. Methods: The participants were 17 single mothers who had stayed in a social welfare facility. Data was collected with an in-depth unstructured interview. Data analysis was done by the grounded theory method. Results: One-hundred twelve concepts and 49 sub-categories were confirmed in the analysis. The sub-categories were grouped into 19 categories; escape from a miserable family, wrong meeting, openness of sex, defenseless state of pregnancy, inevitable result of pregnancy, heartbreak by herself, closure, isolation, difficult situation of being alone, stigma, supporting & protecting, helplessness, seeking, empowering, feeling of loss, conflict, facing issues, assuring a fresh start and becoming-mature. "Being driven over the edge of a cliff" was the key phenomenon which the single mothers experienced during the process of pregnancy. Conclusion: The above results will help nurses assessing single pregnancy mothers' needs and developing a nursing intervention program for supporting them. Therefore, nurses will be able to stop them from "being driven over the edge of cliff". A more vigorous nursing intervention is suggested for the research of the vulnerable classes of medical health care including single pregnant mothers.

A good amount of work has been done on degree of approximation of functions belonging to Lip${\alpha}$, Lip($\xi$(t),r) and W($L_r,\xi(t)$) and classes using Ces$\`{a}$ro, N$\"{o}$rlund and generalised N$\"{o}$rlund single summability methods by a number of researchers ([1], [10], [8], [6], [7], [2], [3], [4], [9]). But till now, nothing seems to have been done so far to obtain the degree of approximation of functions using (N,$p_n$)(C, 1) product summability method. Therefore the purpose of present paper is to establish two quite new theorems on degree of approximation of function $f\;\in\;Lip({\alpha},r)$ class and $f\;\in\;W(L_r,\;\xi(t))$ class by (N, $p_n$)(C, 1) product summability means of its Fourier series.

The purpose of this study was to develop a science gifted education program as a strategy for modulating gifted children's overexcitabilities and to examine the effect of such program on task commitment and creative personality. The results of this study were as follows. First, science gifted education program which modulated gifted children's overexcitabilities showed significant effect on the improvement of task commitment. Looking at sub domains, significant results were obtained at self-regulation. Second, science gifted education program which modulated gifted children's overexcitabilities showed significant effect on the improvement of creative personality. Looking at sub domains, significant results were obtained at the self-conviction and humors. Third, students who experienced the classes showed affirmative responses that the new teaching method was interesting and helpful. Looking at the above results, science gifted education program which modulated gifted children's overexcitabilities can be considered as effective for improving task commitment and creative personality of elementary scientific gifted students.

In our paper, We propose an efficient adaptive coding method using kohonen neural network. An efficient adaptive encoding method using Kohonen net work is discribed through the analysis of those compression methods with the application of the neural network. In order to increase the compression ratio, a image is first divided into 8*8 subimages, then all subimages are transformed by DCT. These DCT sub-blocks are divided into N(4) classes by Kohonen network. Hits are distributed according to the variance of the DCT sub-block. Thus we get N(4)bit allocation matrices. Excellent performance is shown by the computer simulation. so we found that our proposed method is better then classifing subimages by AC energy.

This study aimed to analyze the relationship between the learning perception of aviation service subjects using role play on the interpersonal competence, learning satisfaction, and learning outcomes of college students majoring in aviation service. A survey was conducted targeting 217 university students majoring in aviation service who are enrolled in universities in the metropolitan area and Chungcheong area and have experience in class using role play. In addition, the hypothesis is verified using the structural equation model. Among the perceptions of role play classes experienced by university students majoring in aviation service, 'inter-dependency' was found to have a positive (+) effect on all sub-factors of interpersonal competence. And 'usefulness' confirmed the positive (+) influence relationship with 'temperament for others' and 'communication' except for 'relationship promotion' of interpersonal ability. Among sub-factor of interpersonal competence, it is confirmed that only the factors of 'temperament for others' and 'communication' had an effect on learning satisfaction. And it is proved that learning satisfaction is an important determinant of learning outcomes. Therefore, this study is expected to serve as a basis for deriving an efficient and optimal learning method for practical subjects in aviation service majors.

Seismic risk assessment studies are one of the most crucial instruments for mitigating casualties and economic losses. This work utilizes fragility curves to evaluate the seismic risk of single-story precast buildings, which are generally favored in Marmara's organized industrial zones. First, the precast building stock in the region has been categorized into nine sub-classes. Then, seven locations in the Marmara region with a high concentration of industrial activities are considered. Probabilistic seismic hazard assessments were conducted for both the soil-dependent and soil-independent scenarios. Subsequently, damage analysis was performed based on the structural capacity and mean fragility curves. Considering four different consequence models, 630 sub-class-specific loss curves for buildings were obtained. In the current study, it has been determined that the consequence model has a significant impact on the loss curves, hence, average loss curves were computed for each case investigated. In light of the acquired results, it was found that the loss ratio values obtained at different locations within the same region show significant variation. In addition, it was observed that the structural damage states change from serviceable to repairable or repairable to unrepairable. Within the scope of the study, 126 average loss functions were presented that could be easily used by non-experts in earthquake engineering, regardless of structural analysis. These functions, which offer loss ratios for varying hazard levels, are valuable outputs that allow preliminary risk assessment in the region and yield sensible outcomes for insurance activities.

This study aimed to analyze the appropriateness of chemistry teaching-learning programs for the gifted in science in middle school gifted classes and to propose improvements. For this study, 5 chemistry teaching-learning 4-6 hour programs developed for science gifted classes by Korea Education Development Institute (KEDI) and 3 chemistry teaching-learning programs developed for science gifted classes by three middle schools in K province were selected. A standard model for gifted education programs was used as tool for analyzing the program targets, program contents, teaching-learning methods, and assessment items. The results showed that all chemistry teaching-learning programs for the gifted in science presented well attainable objectives in the program targets. However, most program targets did not offer differentiated objectives from the general education. Program contents of KEDI stresses intensified education, and also presented a high ratio of sub-elements of creativity, which can enhance gifted creativity. On the other hand, program contents developed by three middle schools focused on acceleration in advancement, and presented low ratio of creativity sub-elements, which could be insufficient in enhancing gifted creativity. Differentiated and personalized, integrated science and interscience, updated research contents were hardly found in programs developed by KEDI and three middle schools. However, teaching-learning methods were composed to fit the learning objectives in the teaching process and the procedures, and were made to self-directed learning. There were no assessment for the feedback after class. Therefore, teaching-learning programs for the gifted in science should be developed further in order to fulfill the objectives of gifted education and gifted characteristics. Also, it is necessary to construct infrastructure to carry out the developed teaching-learning programs.
