For fitness-for-service analyses of underground natural gas pipelines, engineering assessment methods against possible defects need to be developed. The assessment methods for high pressure pipeline of KOGAS, was developed using the full size pipe burst tests and the finite element analysis. It included the defect assessment methods for a single and multi-corrosion, corrosion in girth welding part, corrosion in seam welding part, the mechanical damage defects as dent and gouge, crack and large plastic deformation of API 5L X65 pipe. In addition, we developed method to assess pipeline integrity by internal and external load to buried pipeline. Evaluation results were compared with other methods currently being applied to the gas pipeline. The program of Windows environment is made for easily using assessment methods. It provides a consistent user interface, so non-professional technician can easily and friendly use the FFS program from company intranet. Several evaluation programs is easily installed using one installer. Each program constitutes a common input interface and the output configuration program, and evaluation result store and can be recalled at any time. The FFS program based on independent evaluation method is used to evaluate the integrity and safety of KOGAS pipeline, and greatly contribute to safe and efficient operation of pipeline. This paper presents experimental, analytical and numerical investigations to develop the FFS methods for KOGAS pipeline, used as high pressure natural gas transmission pipeline within KOREA. Also, it includes the description of the integrated program for FFS methods.

The purpose of this study was to investigate the process and the effect of pre-service teacher's scaffolding in environmental camp program about global climate change. For this study, developed the environmental camp program based pre-service teacher's scaffolding and applied to 78 $5^{th}$ students. We analyzed the role of pre-service teacher in the process of scaffolding. In the result, the pre-service teachers conducted cognitive scaffolding like as "Focus", "Hint", "Tell or Summarize" and "Technical Help". They carried out the emotional scaffolding like as "Create Cheerful Atmosphere", "Encourage", and "Help in Living". Teaching and learning about global climate change, the theme of the camp, was regarded uncertain and complex. So, pre-service teacher's scaffolding was effective to promote environmental literacy about climate change of primary students (<0.05). The student teachers understanded the characteristics of the children through emotionally close relationships. The primary students were learned easier about global climate change through cognitive and emotional scaffolding. They experienced environmental practice with communal living in camp.

The purpose of this study was to get an implication on teacher education program, by exploring the difficulties pre-service elementary teachers have with their science lessons. 37 pre-service teachers were requested to write an anecdote about their science lessons during their 4 week practicum. By analyzing these anecdotes, the difficulties were grouped into several categories by the researcher, and then reconfirmed by the pre-service teachers themselves. The result showed that there were far more difficulties with practical work (cases: 48), than with content knowledge teaching (cases: 17). Among practical work related difficulties, the most frequent cases were: 1) when they have unexpected result different from scientific theory (cases: 10), 2) when they teach process skill and usage of lab equipments (cases: 8), and 3) when they do not have enough preparation for practical work (cases: 7). Unlike the result of preceding research on secondary pre-service teachers, there was no affective aspect problems. These difficulties also can be divided into 'problems' and 'dilemmas'. Whereas 'problems' can be settled by removing obstacles, 'dilemmas', a conflict-filled situation, require choices between competing values or aims. The use of scientific language, the decision on the level and amount of knowledge they teach, and disposal of unexpected experiment results caused such dilemmas in science lessons. The research results imply practical work should be more strengthened in the elementary teacher education program. And both teacher educators and pre-service teachers need to understand that practical teaching is a complex enterprise accompanying some 'dilemmas'. The role of science teachers as managers of dilemmas could be considered.

Purpose: This study examined how many determinant factors (service dimensions, food quality, and price perception) affect revisit intention. This practical concept is service quality (SERVQUAL), customer satisfaction, and repeated/revisit behavioral intention based on the theory of reasoned action (TRA). Research design, data and methodology: This research applied a hybrid mixed-method comprising exploratory and explanatory sequential design by Creswell (2014). The 400 responses were collected in four townships in Myanmar. This study drilled down to exploratory factor analysis (EFA) followed by confirmatory factor analysis (CFA) prior to test the hypothesized factor structure of all the variables resulted in the form of the goodness of fit. For further data analysis, structural equation modeling (SEM) was applied to test the relationships among the variables of the proposed model. Results: The results showed that perceived service quality, food quality, and price perception have direct effects on customer satisfaction and indirect effect on revisit intention. The perceived service quality has the most significant influence while the food quality has the least influence on customer satisfaction. Conclusions: The results are useful for the restaurant managers to better understand the significant strategic choice factors to improve higher quality service amongst restaurants both domestic and international under the stiff competition.

An inclusive childcare capacity building program was designed to enhance teacher efficacy and attitudes toward the inclusion of childcare teachers. A total of 36 teachers working in childcare facilities in Gyeonggido participated in this study. Nineteen teachers were assigned to the treatment condition and 17 teachers were assigned to the control condition. The program explicitly addressed 15 topics, including screening and diagnosis, early development, characteristics of disability, family support and related services, IEP, and online site observation. The program was primarily delivered by field professionals using adult learning techniques such as small group activities, reflective journal writings, and online consultation. Teachers in the treatment group outperformed teachers in the control group on three measures of teacher efficacy, teacher play efficacy, and attitudes toward inclusion. The results were statistically significant. The increase in teacher efficacy, play efficacy, and attitudes toward inclusion of teachers was attributed to the well-designed program, encompassing early development, disability characteristics, small group discussions, and online support. The results highlight the importance of providing and disseminating a capacity building program for in-service teachers.
