Cured-in-place-pipe(CIPP) is the most adopted trenchless application for sewer rehabilitation to extend the life of the existing sewer without compromising both direct construction and indirect social costs especially applied in the congested urban area. This technology is globally and domestically known to be the most suitable for partial and full deteriorated pipe structure rehabilitation in a sewer system. The typical design of CIPP requires a significant thickness of lining to support loading causing sewage flow interruption and increasing material cost. This paper presents development of a high strength glass fiber composite lining material for the CIPP application and structural test results. The test results exhibit that the new glass fiber composite lining material has 12 times of flexural strength, 6.2 times of flexural modulus, and 0.5 Creep Retention Factor. These test results can reduce lining design thickness 35% at minimum. Even though taking into consideration extra materials such as outer and inner films for actual field applications, the structural capacity of the composite material significantly increases and it reduces 20 percent or more line thickness as compared to the conventional CIPP. We expect that the newly developed CIPP lining material lowers material costs and minimizes flow capacity reduction, and fully replaceable to the conventional CIPP lining materials.

This study examines the awareness of the curriculum of the cabin service major students at 2 year colleges through the CIPP (Context, Input, Process, Product) evaluation model and an empirical analysis on how their awareness affects Service Orientation and Service Hospitality. It was proven that the CIPP evaluation model has a positive effect on the satisfaction of their department, and also has a meaningful effect on Service Hospitality and Service Orientation statistically. However, the satisfaction of their department itself is not associated with the increase of Service Orientation and Service Hospitality so it negatively affected them. Moreover, both the Service Management program(Process) and Service Attitude(Product) have a meaningful effect on Service Hospitality, and Service Hospitality also has a meaningful effect on Service Orientation. So it resulted in a casual relationship among them. As a result, it is desperately necessary to promote an educational environment that will increase the satisfaction of the department and help students to become flight attendants. It is also necessary to increase awareness of the Service Management program(Process) and Service Attitude(Product).

The purpose of this study is to evaluate an airline service training program based on the CIPP model. Evaluation areas were divided into context, input, process, and product. We analyzed the factors which influenced program satisfaction and recommendation of the training program. Two hundred and one learners who participated in an airline service training program were selected for a survey. The results of this study are as follows. The factors which positively influenced training satisfaction were educational goals in context evaluation, interaction between learners and instructors, managing programs in process evaluation, and training performance in product evaluation. The factor which negatively influenced training satisfaction was human resources in input evaluation. On the other hand, the factors which positively influenced training recommendation were educational goal, assessing needs in context evaluation, interaction between learners and instructors, supporting programs in process evaluation, and training performance in product evaluation. The factor which negatively influenced training recommendation was assessing needs in context evaluation. The results of this study are expected to make an important contribution to the development of service training programs in airlines.
